The material transport means 74, which may be of a form known per se, are
When the press body 2 is in the machining stage (the lower forming tool 6 of the stationary lower part 4)
8 and the upper forming tool of the movable upper part 6 are in the machining region (period in which they act on the existing workpiece material), the feed of the workpiece material is stopped, and the press body 2 is in the non-machining period (the period in which the press body 2 is in the non-machining period (the period in which it acts on the existing workpiece material) When the upper forming tool is in a period in which it is separated upward from the workpiece material present in the workpiece area P, the workpiece material is advanced toward the workpiece area P by a predetermined amount.

Therefore, in the above-described press apparatus, for example, a sheet-shaped workpiece material is transported toward the processing area P in the direction indicated by the arrow 76 by the action of the material transport means 74.

With this structure, the receiving container 78 supplied by the action of the container supply mechanism 84 is transported in the direction shown by the arrow 82 by the action of the container transport mechanism 80, and is transferred to the processing area P.
The workpiece is held as required in the workpiece receiving area Q located below. While the receiving container 78 is held in the receiving area Q, the workpiece, which has been punched out in the processing area P of the press body 2 as described above, is dropped into the receiving container 78 and received. It will be done. A predetermined number of workpieces are received in the receiving container 78 (in other words, the movable upper part 6 of the press body 2 moves up and down a predetermined number of times).

Therefore, the drive coupling means 15
When the worm wheels 168 of the rotation adjustment means 152 and 154 are rotated in the direction indicated by arrow 198 (or 200) via 6, the lower crossheads 42 and 44 are simultaneously moved downward (or upward), and the connecting rod 50.52.
56 and 58, the upper crosshead 62 is also moved downward (or upward), thus reducing the distance between the stationary lower part 4 and the movable upper part 6, in other words, the distance between the stationary lower part 4 and the lower forming tool 68 when it is at the top dead center position. The spacing of the upper forming tool (not shown) of the movable upper part 6 is adjusted as required.

Since the illustrated press device has the configuration described above,
It has the following advantages:

First, the crankshaft 20 is composed of a round bar 92 and bushing members 94 and 96 attached to the round bar 92, and includes first crank parts 32 and 34 and a second crank part 3.
6 is the portions 94a and 96a of the bushing members 94 and 96;
In addition, since it is composed of the portion 98a of the bushing member 98, it is easier to process the crankshaft 20 and its accuracy can be increased, compared to conventional crankshafts in which the crank portion is integrally provided. It is possible to cope with increased processing speed.

Second, since the balancer 48 is installed at the center of the crankshaft 20, more specifically, at the substantially center in the axial direction between the parts of the crankshaft 20 supported by the press body 2, the entire press apparatus can be made smaller. It can also handle higher speeds.

In other words, in conventional press equipment, balancers are installed at both ends of the crankshaft, which requires a large space for the balancers, making the entire equipment larger, and also requires increased rigidity of the crankshaft. Furthermore, since there are two balancers, it is necessary to balance them, and it is not possible to respond satisfactorily to increased processing speed. On the other hand, in the illustrated press device, the balancer 48 is mounted substantially in the center of the crankshaft 20, so the space existing within the press device can be effectively used to effectively downsize the entire device. In addition, the balancer 48 is now located at the center of the press body 2 in the width direction, which effectively suppresses vibrations of the device and increases the processing speed. It is also possible to eliminate shortcomings.

Container moving means for moving the container 78 is included. The container moving means includes a pair of rotating members 216 and 218 and a transmission member 220 that is wound between the rotating members 216 and 218. Rotating member 2, which can for example consist of a sprocket

The receiving receptacle 78 is thus moved together with the support base 230.

As described above, referring to FIG.
18 is rotated in the direction shown by arrow 222, the spool 220 moves the tension side 220a of transmission member 220 upwardly in the direction shown by arrow 82, ie, in FIG. In this way, the winding is performed by the action piece 224 provided on the transmission member 220 coming into contact with the receiving container 78 (in the specific example, as understood from FIG. 6, the protrusion 234° of the support base 230).
With the movement of the actuating piece 224 in the direction of the arrow 82, the receiving container 78 located on the container supply area R2 and thus on the support plate 212 is conveyed towards the workpiece receiving area Q and passes through the receiving area Q. The containers are then conveyed to the container discharge area T and thus onto the support plate 1-214. During such transportation, the support stand 230 is supported by the support rollers 208 and is moved while being guided by the guide plates 204 and 206.

The illustrated container transport mechanism 80 further includes, in conjunction with the workpiece receiving area Q, a container restraining means 238 for restraining the receiving container 78 in said receiving area Q, and a container restraining means 238 located above said receiving container 78 in said receiving area Q. The container positioning includes means 240 for selectively positioning the container in an operative position and a lower non-operative position. Mainly referring to FIGS. 5 and 6, the illustrated container restraining means 238 includes a pair of upstream restraining pieces 242 disposed on the upstream side of the receiving area Q when viewed in the receiving container conveying direction indicated by the arrow 82. and a pair of downstream restraining pieces 244 disposed on the downstream side of the receiving area Q as seen in the conveying direction, and the upstream restraining piece 242 moves the receiving container 78 to the receiving area Q by the action of the upstream actuation mechanism 246. A restraining position for restraining (the position shown in FIGS. 5, 6, and 7-B) and a release position for releasing the above-mentioned restraint of the receiving container 78 (the position shown in FIG. 7-A)
The downstream restraining piece 244 is selectively positioned in the restraining position where the receiving container 78 is restrained in the receiving area Q by the action of the downstream actuating mechanism 248 (position shown in FIG. It is adapted to be selectively positioned at the release position to be released. In the specific example, the pair of upstream restraint pieces 242 and upstream actuation mechanism 246 and the pair of downstream restraint pieces 244 and downstream actuation mechanism 248 have substantially the same configuration, and then the upstream restraint piece 242 and the upstream actuation mechanism 248 have substantially the same configuration. The configuration of the side actuation mechanism 246 will be explained.

Referring to FIGS. 7-A and 7-B together with FIGS. 5 and 6, the illustrated upstream actuation mechanism 246 includes a pair of rotating shafts 250 and 252, and a pair of rotating shafts 250 and 252. A pneumatic cylinder mechanism 254 that constitutes an operating source for
It is equipped with To explain further, one rotating shaft 250 is arranged inside the guide plate 204 and is rotatably supported by a support member 256 fixed to a plate member 255 mounted on the bottom surface defining the accommodation space S. .

Further, the other rotating shaft 252 is disposed inside the guide plate 206 and is rotatably supported by a support member 258 fixed to a plate member 255 mounted on the bottom surface defining the accommodation space S. Such rotating shafts 250 and 252
One end side protrudes somewhat forward from the front surface of the accommodation space S, and these protruding ends are rotatably supported by the plate member 260.

The plate member 260 is secured to a mounting member 262, which is mounted to a portion 264 of the container transport mechanism 80. One end of a connecting piece 266 is fixed to the protruding end of the rotating shaft 250 that protrudes from the plate member 260, and the other end of the connecting piece 266 is connected to the connecting member 27 via a connecting bolt 268.
It is rotatably connected to one end of 0. The other end of this connecting member 270 is further rotatably connected to a U-shaped connecting member 274 via a pin member 272. Similar to the rotating shaft 250 described above, one end of a connecting piece 276 is fixed to the protruding end of the rotating shaft 252 that projects from the plate member 260, and the other end of the connecting piece 276 is connected to one end of the connecting member 280 via a connecting bolt 278. The other end of the connecting member 280 is pivotally connected to the connecting member 272 via the pin member 272. on the other hand,
The pneumatic cylinder mechanism 254 is attached to the mounting member 262,
The output rod 254a is screwed onto the connecting member 274 through a through hole (not shown) formed in the mounting member 262. Further, a guide roller 282 is rotatably attached to the pin member 272 attached to the connecting member 274, and the guide roller 282 is movable in the vertical direction within a long hole 284 formed in the plate member 260 and extending in the vertical direction.

As such, when the pneumatic cylinder mechanism 254 is retracted, the guide roller 282 is moved through the connecting member 274, as can be easily understood by comparing FIG. 7-A and FIG. 7-B. is moved downward within the elongated hole 284. In this way, as the connecting member 274 moves, the other ends of the connecting members 270 and 280 are also moved downward, thereby turning the connecting piece 266 in the counterclockwise direction shown by the arrow 286 (Fig. 7-A). At the same time, the connecting piece 276 is connected to the arrow 288.
(Fig. 7-A). Connecting piece 2
When 66 is rotated in this way, the rotating shaft 250 also rotates as shown by the arrow 28.
6, and when the connecting piece 276 is turned in this way, the rotating shaft 252 is also turned in the direction shown by the arrow 288, and as a result of the contraction of the pneumatic cylinder mechanism 252, one of the upstream restraining pieces 242 in the direction shown by arrow 286, and the other upstream restraining piece 242 in the direction shown by arrow 288.
It will be rotated in the direction shown. And pneumatic cylinder mechanism 2

The upper end side of 2 protrudes upward beyond the bottom surface of the receiving container 78 (in the specific example, the support base 230 on which the receiving container 78 is placed), thus causing the receiving container 78 to move in the direction opposite to the direction indicated by the arrow 82. is reliably prevented by the action of the upstream restraining piece 242. On the other hand, the pneumatic cylinder mechanism 25

82 is moved upwardly within the elongated hole 284. In this way, contrary to what has been described above, as the connecting member 272 moves, the other ends of the connecting members 270 and 280 are moved upward, thereby causing the connecting piece 266 to move in the direction of the arrow 290 (7th-B).
), and the connecting piece 276 is rotated counterclockwise as shown by arrow 292 (FIG. 7-B).

When the connecting piece 266 is turned in this way, the rotating shaft 2 is integrally connected to the connecting piece 266.
50 is also rotated in the direction shown by arrow 290, and the connecting piece 2
When 76 is turned in this manner, the rotating shaft 252 is also turned in the direction shown by arrow 292, and as a result of the contraction of pneumatic cylinder mechanism 252, one of the upstream restraining pieces 242 is moved as shown by arrow 290. direction, and the other upstream restraining piece 2
42 is pivoted in the direction shown by arrow 292. When the pneumatic cylinder mechanism 254 is expanded by a predetermined amount, the guide roller 282 is located at the upper end of the elongated hole 284, and the seventh--
The state shown in Figure A will be reached. That is, the rotating shaft 250 is rotated approximately 90 degrees clockwise in FIG. In Figure B, the upstream restraint piece 24 is rotated approximately 90 degrees counterclockwise.
2 is positioned in a substantially horizontal release position. In this release position, as shown in FIG. 7-A, the upstream restraint piece 242 is located below the upper end of the support roller 208 and does not act on the receiving container 78 (in the specific example, the support stand 230). In this way, the above-mentioned restraint of the receiving container 78 is released, and the receiving container 78 becomes movable on the support rollers 208.

Note that the downstream actuation mechanism 248 has substantially the same configuration as the upstream actuation mechanism 246 as described above, and has a pair of rotating shafts 2.
50 and 252, and a pneumatic cylinder mechanism (not shown) constituting an operating source for rotating the rotating shafts 250 and 252, and a downstream restraining piece 244 is fixed to the rotating shafts 250 and 252, respectively. ing. Therefore, the upstream actuation mechanism 2
Similar to the operation of 48, when the pneumatic cylinder mechanism (not shown) of the downstream actuation mechanism 246 is retracted, the contraction of the pneumatic cylinder mechanism causes the rotating shafts 250 and 2 to move in the same manner as described above.
52 is rotated as required to position the downstream restraining piece 244 in a substantially upright restraining position while the pneumatic cylinder mechanism (not shown) is extended. Similarly, the rotating shafts 250 and 2
52 is rotated as required, and the downstream restraint piece 242 is positioned in a substantially horizontal release position.

In addition, the illustrated container positioning means 240 is the positioning member 2.
Contains 94. 5, FIG. 6, FIG. 7-A, and FIG. 7-B, in the specific example, the positioning is the member 2.
Four rollers 94 are provided, and a roller 298 is rotatably attached to the tip of each positioned member 294 via a short shaft 296.

These positioning members 294 are connected to the upstream actuation mechanism 2.
46, two positioning members 294 are fixed to the other end of one rotating shaft 250 (the part existing in the receiving area Q) at intervals in the axial direction, and the remaining two The member 294 is fixed to the other end of the other rotating shaft 252 (the part existing in the receiving area Q) at intervals in the axial direction. Accordingly, as will be readily understood, the four positioning members 294 can be moved between the operative position (the position shown in FIGS. 5, 6, and 7-B) and the inactive position by the action of the upstream actuation mechanism 246. (the position shown in FIG. 7-A). That is, when the pneumatic cylinder mechanism 254 of the upstream actuation mechanism 246 is contracted as required, the rotating shafts 250 and 252 are rotated approximately 90 degrees as required as described above, and the member 294 is in each position. It is positioned in a substantially upright working position (at this time, the upstream restraining piece 242 is positioned in the restraining position).

In this operating position, as shown in FIG. 7-B, each position is on the bottom surface of the receiving container 78 (in the specific example, the bottom surface of the support base 230) where the roller 298 attached to the member 294 is present in the receiving area Q. The receiving container 78 is held at a receiving position located above the support rollers 208. On the other hand, when the pneumatic cylinder mechanism 254 is extended as required, the rotating shaft 254 is expanded as described above.
50 and 252 are rotated approximately 90 degrees as required, and each position is such that the member 294 is positioned in a substantially horizontal non-operative position (at this time, the upstream restraint piece 242 is positioned in the release position). In such a non-operating position, as shown in FIG. 7-A, each position is such that the roller 298 attached to the member 294 is located on the bottom surface of the receiving container 78 in the receiving area Q (in the specific example, the bottom surface of the support base 230). ), and the receiving container 78 is supported on the support roller 208. In the specific example, the container positioning means 240 is moved by the upstream actuation mechanism 246 that moves the member 294 to move the upstream restraining piece 242, but instead of this, a separate actuation mechanism is provided, Such an actuation mechanism may selectively position the member 294 between the operative position and the non-operative position.

In the illustrated press apparatus, furthermore, in the lower part of the communication hole 202 that communicates the processing area P and the accommodation space S, the workpiece processed in the processing area P is placed in the receiving container 78 present in the receiving area Q. A guide member 300 is provided for guiding the passage (FIG. 1). The guide member 300 is composed of a cylindrical member, and its lower end side projects somewhat downward into the accommodation space S from the lower surface of the communication hole 202.

In a specific example, the above-mentioned guide member 300 is preferably further configured as follows. That is, the positioning is done by member 29.
4 is positioned in the working position, and the receiving container 78
When the guide member 3 is held at the receiving position, the guide member 3
00 is located within the receiving container 78, thereby
(The workpiece processed in the processing area P is reliably received in the receiving container 78.) Also, the positioning is such that the member 294 is positioned in the non-operating position and the receiving container 78 is placed in the support roller 2.
08, the lower end of the guide member 300 is located above the receiving container 78 (this ensures that the upper part of the guide member 300 does not come into contact with the guide member 300 when the receiving container 78 is moved). It is preferable to do so.

Next, the illustrated container supply mechanism 84 will be explained with reference to FIGS. 8 and 9 as well as FIG. 2.

The illustrated container supply mechanism 84 includes a moving table 302 and a container supply holding means 304 mounted on the moving table 302.
It is equipped with In a specific example, the container supply holding means 3

Further, rollers 316 and 318 are disposed at both ends of the guide plates 306 and 308 described above.
An endless conveyor belt 320 is wound around the conveyor belt 18 .

In the specific example, roller 316 is connected to guide plates 306 and 3.
The roller 318 is rotatably attached to one end of the guide plate 306 and the plate piece 322 is attached to the other end of the guide plate 306 so that the position can be adjusted freely. (not shown) is rotatably mounted. Further, the conveyor belt 320 is located between the guide plates 306 and 308, and the roller 31
The roller 324 extends substantially horizontally from one end wrapped around the roller 316 toward the roller 316, and is further wrapped around the roller 316 and rotatably mounted between the support members 312 (only one of which is shown in FIG. 8). wrapped around it, and then attached to the mounting member 32
6 (only one of which is shown in FIG. 8) is wound around a roller 328 which is rotatably mounted between 6 (one side is shown in FIG. 8), and reaches the one end wound around the roller 318. The roller 328 is drivingly connected to an electric motor 330 constituting a drive source, and is rotated in the direction indicated by a dashed arrow 332 by the action of the electric motor 330. Therefore, the above-mentioned conveyor belt 320 is moved in the direction indicated by the arrow 334 by the action of the electric motor 330, in other words, the upper running portion 320a thereof is moved toward the guide plate 300.
and 308 from the other end side toward one end side thereof.

Then, by changing the position of the plate pieces 322 attached to the guide plates 306 and 308, the tension of the conveyor belt 320 is adjusted. In the specific example, the receiving container 78 is placed on the upper running portion 320 of the conveyor belt 1-320, and is conveyed as required (FIG. 9) by movement of the conveyor belt 320 in the direction indicated by the arrow 334. reference).

In connection with this, a support plate 336 is provided below the upper traveling portion 320a of the conveyor belt 320. The support plate 336 is the guide plate 306
and the upper running portion 32 from one end of 308 to the other end.

The moving mechanism 340 includes a pair of rails 344 and 346 disposed at both ends of a base 342. Rails 344 and 3
46 are fixed to the upper surfaces of mounting plates 348 and 350 respectively attached to both ends of the base 342, and extend in the fore-aft direction. On the other hand, mounting plates 352 and 354 are attached to both ends of the moving table 302, and U-shaped support brackets 356 and 358 are fixed to the lower surfaces of the mounting plates 352 and 354, respectively. Furthermore,

60 is supported by one rail 344 (specifically, a portion between both flanges of the roller 360 is supported by the rail 344), and a cylindrical roller 362 is rotatably attached to the other support bracket 358. The roller 36
2 is supported by the other rail 346. Therefore, since both flanges of the rollers 360 are located on both sides of the rail 44 at one end of the moving table 302, the moving table 302 is reliably moved in the front-back direction along the rail 344. The moving mechanism 340 further includes a pneumatic cylinder mechanism 364 that moves the moving table 302. The main body side of the pneumatic cylinder mechanism 364 is the base 3

It is located above 392. Therefore, when the moving table 302 moves upward, the rollers 390 and 392 come into contact with the projections of the restraining members 386 and 388, and thus the moving table 302
2 upward movement, in other words, rollers 360 and 362
is reliably prevented from coming off the rails 344 and 346.

With this configuration, when the pneumatic cylinder mechanism 364 is extended, the moving rod 368 is moved toward the back side in the direction perpendicular to the plane of the paper in FIG. 8 (upward in FIG. 2), and the container supply holding means 304 is positioned at the position indicated by the solid line in FIG. 2 (as understood from FIG. (supplied to region Q). At the time of such movement,
Pinions 270 and 272 move backward in the front and back direction while rotating on racks 274 and 278 fixed to base 342, and the rotation of pinions 270 and 272 moves table 302 via racks 276 and 280.

Each blocking member 414 extends upwardly, with one of them positioned between guide plate 306 and conveyor belt 320 and the other of them positioned between guide plate 308 and conveyor belt 320.
It is located between 0. First, the pneumatic cylinder mechanism 412
is extended, the blocking member 414 is moved upward, and the blocking member 414 is placed in the operating position shown by the solid line in FIG. On the other hand, when the pneumatic cylinder mechanism 412 is retracted, the blocking member 414 is moved downwardly, and the blocking member 414 is shown in phantom in FIG. The blocking member 414 is located at a non-working position (in such a non-working position, the blocking member 414 is located below the upper running portion 320a of the conveyor belt 320). Further, the forced moving means 398 is disposed so as to be movable in the receiving container supply direction in relation to the receiving container 78 located at the downstream end in the receiving container supply direction on the transport heald 320, and moves the receiving container 78 to the container transport mechanism. It acts to forcibly move toward the supply area Q of 80.

The illustrated forced displacement means 398 includes a pneumatic cylinder mechanism 416 attached to the inner wall plate 338. The output rod 416a of the pneumatic cylinder mechanism 416 protrudes through a through hole (not shown) formed in the inner wall plate 338, and the support member 418 is attached to the protruding end of the output rod 416a.
is installed. The support member 418 is located between the pair of blocking members 414 of the second movement blocking means 396, and a pair of pneumatic cylinder mechanisms 420 (only one is shown in FIG. 9) is attached to the upper surface of the support member 418, and a pneumatic cylinder Mechanism 42
A moving member 422 is attached to the output rod 420a of 0. Each moving member 422 extends upwardly, one of which is located between guide plate 306 and transport belt 320 and the other of which is located between guide plate 308 and transport heald 420. In the specific example, the pair of moving members 422 of the forced moving means 398 are arranged inside the pair of movement blocking parts 404 of the first movement blocking means 394 and the pair of blocking members 414 of the second movement blocking means 396. It is set up. Therefore, when the pneumatic cylinder mechanism 416 is extended, the support member 418 is moved in the receiving container supply direction, that is, to the left in FIG.

On the other hand, when the pneumatic cylinder 41f#416 is contracted, the support member 418 is moved in the opposite direction to the receiving container supply direction, that is, to the right in FIG. It is located at the second position shown by the solid line. Further, when the pneumatic cylinder mechanism 420 is extended, the moving member 422 is moved upward, and the moving member 422 is shown by a solid line in FIG.

The first movement prevention means 394 and the second movement prevention means 3
96 and the forced displacement means 398, the receiving receptacle 78
The support stand 230 on which is placed is constructed as follows.

Referring to FIG. 9, four notches 424 (
(one shown in FIG. 9) is formed, and a support stand 23 is formed.
Four notches 426 (one shown in FIG. 9) are formed at intervals in the width direction at the lower rear end of the receiving container 0 in the transport direction. A pair of outer notches 424 (one of which is shown in FIG. 9) formed at the front end of the support base 230 prevents the movement prevention portion 404 of the first movement prevention means 394 and the second movement prevention means 396. Member 414
A pair of inner notches 426 (one of which is shown in FIG. 9) formed at the rear end of the support base 230 corresponds to the moving member 422 of the forced moving means 398. It is set in.

Therefore, as shown in FIG. 9, the first movement preventing means 394
is in the operating position, the pair of movement prevention parts 404 of the prevention member 406 can come into contact with the bottoms of the pair of outer notches 424 formed at the lower part of the front end of the support base 230, and the movement prevention parts 404 abuts against the notch 424, the movement of the support base 230, and therefore the receiving container 78, is reliably stopped. On the other hand, the first movement preventing means 3
94 is in the non-operating position, the pair of movement prevention parts 404 retreat below the support plate 232 of the support stand 230 and do not act on the support stand 230 on the conveyor belt 320 and therefore on the receiving container 78. . Further, when the second movement blocking means 396 is in the operating position, the pair of blocking members 414 can come into contact with the bottoms of the pair of outer notches 424 formed at the lower part of the front end of the support base 230. When the blocking member 414 comes into contact with the notch 424, the movement of the support base 230, and thus the receiving container 78, is reliably stopped. On the other hand, the second movement preventing means 3
When 94 is in the non-operating position, the pair of blocking members 414 are retracted below the support plate 232 of the support base 230 and do not act on the support base 230 on the conveyor belt 320 and therefore on the receiving container 78. Furthermore, the receiving container 7
8 is stopped by the first movement preventing means 394, when the forced moving means 398 is brought to the operating position, the pair of moving members 422 move from the inner side formed at the lower part of the rear end of the support base 230. The support stand 230, and therefore the receiving container 78, is moved from the second position to the first position of the forced moving means 39B, which is located within the pair of notches 426 and will be described later, to the supply area R of the container transport mechanism 80. be forcibly moved towards. On the other hand, when the forced movement means 398 is in the non-operating position, the pair of moving members 422 retreat below the support plate 232 of the support stand 230 on the conveyor belt 320 and act on the support stand 230 and therefore the receiving container 78. Never. In the above-mentioned specific example, the pair of outer notches 426 formed at the rear end of the support base 230 are similar to the pair of outer notches 424 formed at the front end thereof, and the first movement Movement blocking section 404 of blocking means 394 and second movement blocking means 39
The pair of inner notches 424 provided at the portions corresponding to the blocking members 414 of No. 6 and formed at the front end of the support base 230 are similar to the pair of inner notches 424 formed at the rear end.
26, it is provided at a location corresponding to the moving member 422 of the forced moving means 398. Therefore, as is easily understood, no problem occurs even if the support stand 230 is placed on the conveyor belt 320 with the front and rear directions reversed.

In the specific example, a forced moving means 398 is provided to forcibly move the receiving container 78 toward the supply area R of the container transport mechanism 80, but the action of the transport belt 320 moves the receiving container 78 as required. If the forced movement means 398 can be reliably moved as described above, this forced movement means 398 can be omitted.

Next, referring to FIG. 10 together with FIG. 2, the illustrated container discharge holding mechanism 86 will be explained. The illustrated container discharge holding mechanism 86 includes a moving table 0 and a container holding means 2 attached to the moving table 0. The container holding means 2 is supplied from the container supply mechanism 84 and is connected to the receiving area Q.
It is desirable to hold all the receiving containers 78 discharged from the discharge area T through the container, and in a specific example, two containers are provided corresponding to the container supply and holding means 304. The illustrated container holding means 2 has spaced apart guide plates 4 and 6. A bottom wall plate 8 is fixed between the guide plates 4 and 6, and both ends of the bottom wall plate 8 are attached to the movable table 0 via support legs 440. Guide plates 4 and 6
As shown in FIG. 10, the guide plates 4 and 6 are inclined downwardly from one end adjacent to the discharge area T of the container transport mechanism 80 to the other end, and there is a longitudinal section between the guide plates 4 and 6. A plurality of support rollers 442 are rotatably mounted at intervals. Further, a stop member 4 is provided between the other ends of the guide plates 4 and 6.
44 is arranged, and the stop member 444 is an L-shaped mounting member 4.
46 is fixed to the bottom wall plate 8.

Therefore, as is easily understood, when the receiving container 78 is discharged from the discharge area T to the container holding means 2, the receiving container 78
8 moves downwardly on the support roller 442 toward the stop member 444 due to its own weight, and is held on the support roller 442 as required by abutting against the stop member 444.

The movable table 0 to which the container holding means 2 is mounted is moved to the base 450 in the front-back direction (in the vertical direction in FIG. 2, in the direction perpendicular to the plane of the paper in FIG. 10) via the moving mechanism 448.
It is attached so that it can be moved freely. The moving mechanism 448 that moves the moving table 0 is the moving mechanism 3 that moves the moving table 302 (FIG. 8) of the container supply mechanism 84.
It has substantially the same configuration as 40. That is, the moving mechanism 448
is a pair of rails 452 arranged at both ends of the base 342
and 454, and rollers 460 and 462 rotatably attached to both ends of the moving table 0 via support brackets 456 and 458 (in the specific example, one roller 460
The rollers 460 and 462 are supported by the rails 452 and 454. The moving mechanism 448 further includes the pneumatic cylinder mechanism 4
64 , and an output rod (not shown) of the pneumatic cylinder mechanism 464 is connected to the moving rod 466 .

Pinions 468 and 47 are provided at both ends of the moving rod 466.
0 is rotatably mounted, and the binions 468 and 470 are mounted on racks 472 and 474 fixed to the base 450 side, and racks 476 and 47 fixed to the movable table 0 side.
8 and are engaged with the respective side racks. In embodiments, support brackets 456 and 45 are further provided to ensure that upward movement of the moving table 0 is prevented.
8 is rotatably mounted with rollers 480 and 482, and correspondingly, the base plate 450 is equipped with the rollers 480 and 482.
Restraint members 484 and 486 having protrusions projecting upwardly from 82 are attached via L-shaped members 488 and 490. Therefore, the moving table 0 is on the rail 452
and 454 in the front-back direction. When the pneumatic cylinder mechanism 464 is extended, the moving rod 466 is moved toward the back side in the direction perpendicular to the plane of the paper in FIG. 10 (upward in FIG. 2), and the container discharge holding mechanism 86 is Once positioned at the position indicated by the two-dot chain line, as can be understood from FIG. On the other hand, when the pneumatic cylinder mechanism 464 is retracted, the moving rod 466
is moved toward the front side in the direction perpendicular to the plane of the paper in FIG. 10 (downward in FIG. 2), and the container discharge holding mechanism 86 is positioned at the position shown in solid line in FIG. As can be understood from FIG. 2, the receiving container 78 in the discharge area T is discharged toward the container holding means 2 located at the rear in the longitudinal direction).

Referring to FIG. 2, in relation to the container holding means 2 described above, a pneumatic cylinder mechanism 492 is disposed on the side of the discharge area T opposite to the side on which the container holding means 2 is disposed. It is set up. When the pneumatic cylinder mechanism 492 is extended, its output rod 492a projects into the discharge area T, as shown by the two-dot chain line in FIG. Discharge toward means 2.

On the other hand, when the pneumatic cylinder mechanism 492 is contracted, its output rod 492a retreats from the discharge area T and does not act on the receiving container 78 in the discharge area T, as shown by the solid line in FIG. In the specific example, openings 494 are formed at required locations on the guide plate 204, and when the pneumatic cylinder mechanism 492 is extended, its output rod 492a is made to protrude into the discharge area T through the openings 494.

Control System Next, referring mainly to FIG. 2, the control system of the illustrated press apparatus will be described. In the illustrated example, eight detection means are provided for detecting the support base 230 on which the receiving container 78 is placed. Detection means S1 and S2
is arranged at the downstream end of each container supply holding means 304 of the container supply mechanism 84 when viewed in the container supply direction. Detection means S3
is arranged in the supply area R of the container transport mechanism 80. The detection means S4 is disposed in the receiving area Q of the container transport mechanism 80. The detection means S5 is arranged between the supply area R and the receiving area Q. Further, the detection means S6 is arranged in the discharge area T of the container transport mechanism 80. Furthermore, the detection means S7 and S8 are arranged at the upstream end of each container holding means 2 of the container ejection holding mechanism 86 in the container ejection direction. These detection means S1 to S8 can be constituted by mechanical microsinches or proximity switches which are known per se.

In the container feeding mechanism 84, the conveyor belt 320 is constantly moved in the direction shown by the arrow 334 (FIG. 8), and the blocking member 406 of the first movement blocking means 394 is normally in the operating position shown by the solid line in FIG. held by the second movement preventing means 39
The blocking member 414 of No. 6 is held in the operating position shown by the solid line in FIG.
20 is held in a second position shown in solid lines in FIG. 9, and its moving member 422 is held in an active position shown in solid lines in FIG. Therefore, the pair of movement prevention parts 404 of the first movement prevention means 394 are inserted into the pair of outer notches 424 formed at the front end of the support base 230 located at the downstream end of the container supply and conveyance means 304 in the container supply direction. Support stand 230
The support stand 230 (therefore, the receiving container 78), which is located at the downstream end in the container supply direction, is held in the state shown in FIG. Further, the pair of blocking members 414 of the second movement blocking means 396 are formed in a pair of outer notches formed at the front end of the support base 230 located second from the downstream end in the container supplying direction of the container supplying and holding means 304. 424 (K) to prevent the movement of the support stand 230, and the support stand 230 located second from the downstream end in the container supply direction (therefore, the receiving container 7
8) is also maintained in the state shown in FIG. Furthermore, the pair of moving members 422 of the forced moving means 398 move toward the support stand 2 located at the downstream end of the container supplying and holding means 304 in the container supplying direction.
30 (see FIG. 9).

In such a state, the receiving container 78 is transported from the supply region R to the receiving region Q of the container transport mechanism 80 as described later, and the detection means S5 detects the support base 230 (therefore, the receiving container 7
8), the pneumatic cylinder mechanism 400 (Fig. 9)
is emasculated. Thus, ζ first movement blocking means 394
The blocking member 406 is positioned in the non-operating position shown by the two-dot chain line in FIG.

Once pneumatic cylinder mechanism 400 is retracted, pneumatic cylinder mechanism 416 (FIG. 9) is then energized.

As a result, the pneumatic cylinder mechanism 416 is extended, and the pneumatic cylinder mechanism 420 (FIG. 9) is attached via the mounting member 418.
is moved from the second position to the first position shown by the two-dot chain line in FIG. During such movement, the movable member 422 is held at the operating position, and therefore the movable member 422 acts on the rear end of the support base 230 and forcibly moves in the supply direction toward the supply area R. urge (
Note that at this time, since the conveyor belt 320 is also moving in the direction shown by the arrow 334, the conveyor belt 320 is also moving in the direction indicated by the arrow 334.
8).

As described above, the receiving container 78 is moved and supplied to the supply area R as required (in a specific example, in order to allow the receiving container 78 to be supplied to the supply area R,
(The upper part of one end of the guide plate 206 is cut out as required) and the detection means S3 are attached to the support base 23 supplied above.
0 (and thus receiving container 78), which deenergizes pneumatic cylinder mechanisms 412 and 420 (FIG. 9) and energizes pneumatic cylinder mechanism 400 (FIG. 9). When the pneumatic cylinder mechanism 412 is deenergized and contracted, the blocking member 414 of the second movement blocking means 396 moves to the ninth position.
The receiver H78, which was positioned in the non-operating position shown by the two-dot chain line in the figure and stopped by the second movement preventing means 396, is moved toward the first movement preventing means 394 by the action of the conveyor belt 320. Ru. Further, when the pneumatic cylinder mechanism 420 is deenergized and contracted, the moving member 422 of the forced moving means 396 moves to the non-operating position shown by the two-dot chain line in FIG. (shown in the second position), and the moving member 422 does not act on the receiving receptacle 78 of the conveyor belt 320.

Further, when the pneumatic cylinder mechanism 400 is energized and expanded, the movement blocking portion 404 of the first movement blocking means 394 is positioned at the operating position. In this way, the receiving container 78 that is being moved by the action of the conveyor belt 320 (the receiving container 78 located at the downstream end of the conveyor belt 320 in the container supply direction) can come into contact with the movement blocking portion 404 . Thereafter, the pneumatic cylinder mechanism 416 (FIG. 9) is deenergized.

As a result, the pneumatic cylinder mechanism 416 is contracted, and the pneumatic cylinder mechanism 420 is connected to the first cylinder via the mounting member 418.
from the position to the second position. During such movement, since the moving member 422 is held at the non-operating position, the moving member 422 does not touch the conveyor belt 32.
It does not act on the receiving container 78 that is being moved by the zero.

As described above, the receiving container 78 located at the downstream end of the upper portion of the conveyor belt 320 in the container supply direction is moved to the first movement blocking means 3.
94, the pair of outer notches formed at the front end of the support base 230 comes into contact with the pair of movement blocking parts 404 of the blocking member 40.6 in the operating position, and the receiving container 78 is moved. The movement is reliably stopped (the receiving container 78 is maintained in the state shown in FIG. 9). When the receiving container 78 is moved to the position shown in FIG. pedestal 230), which energizes pneumatic cylinder mechanisms 412 and 420 (FIG. 9). When the pneumatic cylinder mechanism 412 is energized and expanded, the blocking member 414 is positioned at the operating position, and the support stand 230 (
Therefore, the receiving container 78) is also reliably stopped by the blocking member 414 (thereby, the movement of the support stand 230 located subsequent to the support stand 230 is also stopped). Furthermore, when the pneumatic cylinder mechanism 420 is energized and expanded,
The moving member 422 is positioned at the operating position, and the upper end of the moving member 422 is positioned within a notch 426 formed in the rear end of the support base 230 that is stopped by the first movement preventing means 394.

Thus, the receiving container 78 containing no workpiece is transferred from the container supply mechanism 84 to the container transport mechanism 80.

It is supplied to the supply area R, and in the container supply mechanism 84, the next receiving container 78 becomes ready for supply.

In the specific example, the following control is further performed in relation to the detection means S1 and S2. First, the first movement preventing means 39
4 is positioned at the operating position, the detection means Sl (or 32) continues for a predetermined period of time to detect the support base 2.
30 is not detected, in other words, when the support stand 230 and therefore the receiving container 78 are not present on the container supply holding means 304 located at the front (or rear) in the longitudinal direction, the pneumatic cylinder mechanism 364 (FIG. 8) Disenergized (or energized). As a result, the pneumatic cylinder mechanism 364 is contracted (or expanded), and the container supply/holding means 304 is positioned at the position shown by the dashed double-dashed line (or solid line) in FIG. In this way, when the supply of the receiving container 78 from the container supplying and holding means 304 located at the front (or rear) in the longitudinal direction is completed, the receiving container 78 is then supplied from the container supplying and holding means 304 located at the rear (or front) in the longitudinal direction. It is supplied to the supply area R of the container transport mechanism 80.

In addition, if the detection means S1 and 82 do not detect the support base 230 (therefore, the receiving container 78) for a predetermined period of time even though both first movement prevention means 394 are positioned at the above-mentioned operating position, in other words, If the support stand 230 is not present on both container supply and holding means 304, a warning lamp (not shown) lights up, indicating that the receiving container 78 to be supplied to the operator is not present on the container supply and holding means 304. Let me know.

The container transport mechanism 80 and the container discharge holding mechanism 86 are controlled as follows.

When a predetermined number of machining operations are completed in the press body 2 as described above by the vertical movement of the movable upper part 6 (the number of machining operations can be known by detecting the number of revolutions of the crankshaft 20, for example), the press body 2 2 stops. In addition, as mentioned above, the workpiece is placed in the receiving area Q in the accommodation space S.
A predetermined number of workpieces are accommodated in the receiving container 78 at the time when the press main body 2 is stopped. When the press body 2 is stopped, the pneumatic cylinder mechanism (not shown) of the downstream actuation mechanism 248 and the pneumatic cylinder mechanism 254 (not shown) of the upstream actuation mechanism 246 (FIGS. 5 and 6) are activated.
) is energized. When the pneumatic cylinder mechanism of the downstream actuation mechanism 248 is energized and extended, the rotation axes 250 and 2
52, the pair of downstream restraining pieces 244 are positioned at the release position. Furthermore, when the pneumatic cylinder mechanism 254 of the upstream actuation mechanism 246 is energized and expanded, the rotating shaft 25
A pair of upstream restraint pieces 242 are connected to the seventh
7-A, and each position positions member 294 in the inactive position shown in FIG. 7-A. In this way, as shown in FIG. 7-A, the receiving container 78 in the receiving area Q is supported by the support rollers 20B, and the restraining pieces 242 and 244 of the receiving container 78 are
The restraint by the support roller 208 is released, and the receiving container 78
be able to move freely on top.

After that, the electric motor M is rotated. Thus,
Rotating member 218 is rotated in the direction shown by arrow 222, and the tension side 220a of transmission member 220 is moved in the direction shown by arrow 82. In this way, the winding is carried out on the transmission member 22.
One working piece 224 provided in the receiving area Q acts on the support stand 230 in the receiving area Q, and the other acting piece 224 acts on the support stand 230 in the supply area R (such support stand 230 is set in advance in the supply area as described above). The movement of the transmission member 220 causes the winding to move from the support base 230 located in the receiving area Q to the receiving container 78 (into which a predetermined number of workpieces are placed). ) and the support stand 230 located in the supply area R, and therefore the receiving container 78 (no workpiece is accommodated in such receiving container 78), are supported by the supporting rollers 208 and guided. 204 and 206 in the direction shown by the arrow 82.

The receiving container 78 is thus transported, and the receiving container 78 being transported from the supply area R to the receiving area Q is detected by the detection means S.
5, the detection means S5 detects the support match 230. Then, as described above, the pneumatic cylinder mechanism 400 (FIG. 9) of the container supply mechanism 84 is deenergized, and a new receiving container 78 is supplied to the supply area R of the container transport mechanism 80 as described above. Ru. Also, in this case, the pneumatic cylinder mechanism (not shown) of the downstream actuation mechanism 248 is deenergized, and the downstream restraining piece 24 is
4 is positioned at the restraining position shown in FIG.

Then, when the support stand 230 from the supply area R, and therefore the receiving container 78, is transported to the receiving area Q, the detection means S4 detects the support stand 230. In this way, the rotation of the electric motor M is stopped, and the upstream operating mechanism 246
The pneumatic cylinder mechanism (FIGS. 5 and 6) is deenergized, and the upstream restraining piece 242 is moved to the restraining position shown in FIGS. 5, 6, and 7-B via the rotating shafts 250 and 252. and each position positions member 294 in the operative position shown in FIGS. 5, 6, and 7-B. In this way, the upstream restraint piece 242 and the downstream restraint piece 244 are positioned at the restraining position, and the support stand 230 conveyed to the receiving area Q, and therefore the receiving container 78, are securely held in the receiving area Q.

Furthermore, when the positioning member 294 is positioned at the operating position, each roller 298 acts on the lower surface of the support base 230 to move it upward, and the receiving container 78 held in the receiving area Q is moved as shown in FIG. and is held in the receiving position shown in FIG. 7-B. Further, when the detection means S4 detects the support stand 230, the press main body 2 is operated again, and the workpiece material 5 is processed as required in the processing area P. At this time, the receiving container 78 in the receiving area Q is reliably held in the receiving area Q by the action of the restraining pieces 242 and 244, and is securely held in the receiving position by the action of the member 294. Therefore, the workpiece processed in the processing area P passes through the communication hole 202 and enters the receiving container 7.
It will definitely fall within 8.

Furthermore, when the support stand 230 and therefore the receiving container 78 from the supply area R are transported to the receiving area Q, the supporting stand 230 and therefore the receiving container 78 located in the receiving area Q are transferred from the receiving area Q to the discharge area. Transported to T. Thus,
The detection means S6 detects the support base 230, and the pneumatic cylinder mechanism 492 is energized. When the pneumatic cylinder mechanism 492 is extended, its output rod 492a acts on the support 230 located in the discharge area T, and the support 230 and therefore the receiving container 7 are discharged onto the container holding means 2. (In the specific example, the upper portion of the other end of the guide plate 206 is notched as required to allow the above-described evacuation of the receiving container 78). The receiving container 78 discharged onto the container holding means 2 is moved by its own weight on the support roller 442 toward the stop member 444, and is moved to the receiving container 78 held on the stop member 444 or the container holding means 2. Due to the abutment, the container holding means is held on the 2 as required. Then, the pneumatic cylinder mechanism 492 is retracted, and its output rod 492a is retracted from the discharge class MiT.

In this way, the receiving container 78 containing the workpiece is transported from the receiving area Q to the discharge area T, and the pneumatic cylinder mechanism 49
2, the container holding means of the container discharging and holding mechanism 86 is discharged and held onto the container 2.

On the other hand, a new receiving container 78 is conveyed from the supply area R to the receiving area Q to which the receiving container 78 was moved.

The receiving container 78 is held in the receiving area Q, and the workpiece processed in the processing area P is held in the receiving area Q.
are accommodated as required in a receiving container 78 held at

As is easily understood, when there is no new receiving container 78, in other words, when the receiving container 78 is not supplied from the supply area R to the receiving area Q, the detection means S4 detects the support stand 230. There's nothing to do (, therefore,
Operation of the press body 2 is not resumed until a new receiving container 78 is filled.

In the specific example, the following control is further performed in relation to the detection means S7 and S8. First, the detection means 37 (or S8
) continuously detects the support stand 230 for a predetermined period of time, in other words, the required number of support stands 230, and therefore the receiving containers 78, are held on the container holding means 2 located at the front (or rear) in the front-rear direction. If the next receiving container 78 cannot be discharged, the pneumatic cylinder mechanism 464 (10th
) is deenergized (or energized). As a result, the pneumatic cylinder mechanism 464 is contracted (or expanded), and the container holding means 2 is positioned at the position shown by the solid line (or the two-dot chain line) in FIG. Thus, the discharge area T of the container transport mechanism 80
When the discharge of the receiving container 78 to the container holding means 2 located at the front (or rear) in the front and rear direction from the discharge area T is completed, the receiving container 78 is then moved to the container holding means located at the rear (or front) in the front and back direction from the discharge area T. It is discharged onto said 2.

In addition, when the detection means S7 and 88 continuously detect the support stand 230 for a predetermined period of time, in other words, the required number of support stands 230 are on both container holding means 2, and therefore the receiving container 78
is held and the next receiving container 78 is transferred to the container discharge holding mechanism 86.
If the receiving container 78 cannot be discharged onto the container holding means 2, a warning lamp (not shown) lights up to inform the operator that the receiving container 78 cannot be discharged onto the container holding means 2.

Although a specific example of a press apparatus configured according to the present invention has been described above, the present invention is not limited to this specific example, and various modifications and changes can be made without departing from the scope of the present invention. be.

For example, in the specific example, the receiving container 78 is
0 and is transported integrally with the support stand 230; however, instead of this, the receiving container 78 may be directly transported.
