Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a centering device that aligns a supplied article with the gripping center when gripping an article, and in particular, centers stacked articles such as cathode ray tube panels with masks fitted on the inner surface. It is an object of the present invention to provide a device for centering articles in order to transfer them to a separating device for separation. I will now talk about the necessity of separating the cathode ray tube panel and the mask fitted into its inner surface.

As is well known, in the case of cathode ray tubes for color televisions, in order to coat the inner surface of the cathode ray tube with phosphor, it is necessary to fit a mask prior to the coating operation, and this must be removed after the coating.

To briefly explain this point below, the 21st to 22nd
As shown in the figure, pins A for mask fitting are fixed to the inner side wall of the cathode ray tube panel P at four locations, and pins A for mask fitting are fixed to the outer periphery of the steel plate mask M as well. A leaf spring B having a small hole is attached. Then, the pin A is fitted into the small hole B' of the leaf spring, and the panel P and the mask M are fitted and integrated, and a phosphor coating operation is performed. After coating, the panel and mask that are in the above-mentioned fitted state are separated. To remove the mask M from the panel P, bend the leaf spring B on the mask side and push the leaf spring against the pin on the panel side. After removing it from A, it is necessary to move the two relatively in parallel. However, since the gap between the inner surface of the panel and the leaf spring is approximately 5 mm, it is difficult to remove the panel and mask without damaging both.
This is quite difficult and requires highly accurate separation equipment.

By the way, there have been attempts in the past to separate panels and masks using automatic machines, but conventional mask separation devices are designed for a single type of pipe with a fixed size. It was not possible to process several types of pipes of different sizes at the same time.
That is, in the conventional apparatus, a structural problem was that the panel and mask had to be positioned twice: immediately before and immediately after the separator main body. In other words, since two centering devices were required for positioning, the device became complicated, and moreover, high-speed separation was impossible. Further, when separating the mask, not only is an additional power required to stop the rotation of the mask, but there is also a drawback that the mask is deformed when the mask is fixed. In particular, with the conventional type, in order to separate the mask attached to a multi-tube cathode ray tube, a centering device, a separation device, and a conveyance line corresponding to the tube type are required, and improvements are desired. was.

Here, the present invention uses a link mechanism to move several sets of gripping rollers centripetally so as to bring them into contact with the periphery of the supplied article, so that the article can be centered with a simple mechanism. This is what I did.

<Structure> The present invention will now be described in detail with reference to the embodiments shown in the drawings. In the following example, a cathode ray tube panel P fitted with a mask M is used as a transferred article (supplied article), and after being centered, it is sent to a separation device by a transfer device, where the panel P and mask M are This example shows a case in which it is separated from the FIG. 1 is a plan view of the entire device, and the essential parts of the device are a centering device 2 provided on the top surface of the frame (1), and a transfer device 3 installed at the rear upper part of the frame. and a mask remover 4 built into the lower surface of the centering device. In addition, as an accompanying device,
A top chain conveyor 5 for feeding the fitted panel/mask P/M is attached to the centering device 2, and a conveyor 6 for discharging the separated masks M is also attached.

Of the above-mentioned devices, the centering device 2 will first be explained with reference to FIGS.
2, and two upper and lower center links 13 and 14 are rotatably attached to the post (see FIG. 6). At both ends of these center links, there are locking pins 13',
One end of the link plates 15a, 15b and 16a, 16b is rotatably attached via 14', and the other end is fitted into a guide mechanism 17, which will be described below. The guide mechanism 17 includes a pair of left and right guide rails 18 and 19 mounted on the board 11, sliding frames 20a and 20b loosely fitted to the guide rails, and sliding frames loosely supported by a pair of upper and lower guide rails 18' and 19'. It consists of moving frames 21a and 21b, and the link plate 15a,
15b and 16a, the other ends of 16b are pivotally connected.
By the way, as shown in FIG. 4, one sliding frame 20a is constructed of an L-shaped member, and a cylinder 22 for operating the link is provided between its bent end and the base plate 11. Arrange. Similarly, a cylinder 23 similar to the above is attached to one of the other pair of sliding frames 21b, 21b, and when this cylinder operates, the sliding frame moves inward. Configure it so that it moves forward centripetally.

A presser roller 24 similar to that described above is attached to the front surfaces of the presser rollers 20a and 20b, but as for the sliding frame 20b located on the right side, the mounting piece 25 of the presser roller 24 rises and falls as it slides. Make it wet.
That is, as clearly shown in FIGS. 8 and 9, a bracket 26 is formed on the sliding frame main body 20b, and the mounting piece 25 is rotatably pivoted to this bracket via a support pin 27, and the base of the mounting piece is 25' itself is used as a counterweight so that the mounting piece 25 normally maintains the raised state as shown in FIG. The upper side of this mounting piece is defined as a cam side 25'', and when the cam follower 28 is brought into contact with this cam side and the sliding frame 20b retreats, the cam side and the cam follower interact with each other. When the entire structure is laid down (as shown by the imaginary line in Fig. 8) and the sliding frame moves forward, the mounting piece 25 automatically rises due to the posture control action of the counterweight. This is a machine frame for mounting, and the symbols KS, KS ₁ to KS ₃ attached to the cylinders 22 and 23 respectively indicate proximity switches attached to the circumferential surface of the cylinders.In addition, the symbol 29 in FIG. Conveyor sprocket wheel, 30 is a take-up device,
31 is a motor for driving the conveyor, and reference numeral PS in FIG. 4 is a phototube switch for detecting the arrival of a panel mask.

10 to 14, regarding the transfer device 3 used to guide the panel mask P/M centripetally gripped by the centering device 2 to the next stage mask removing machine 4, Its configuration will be explained. As shown in FIGS. 1 to 3, the transfer device 3 is provided at the rear (back side) of the frame 1, and consists of a column 35, an upper rail 36, a traveling unit 37, an elevating post 38, an elevating unit 39, and the like.

The traveling unit 37 is mounted on a guide roller 37a with respect to a rail portion 36a attached to an upper beam member 36.
The lifting unit 39 is mounted so as to be freely movable in the horizontal direction via a rail part 41, and the lifting unit 39 is attached to the lifting post 38, which is also vertically installed on the lower surface of the traveling unit 37, so as to be able to rise and fall freely. ing. Arms 42, 42 projecting forward are fixed to the elevating post, and a mounting rod 43 of the suction unit is fixed to the tips of the arms 42, 42. A fixed suction unit 44 is attached to one end, and a rotatable suction unit 45 is attached to the other end. Numerals 44a and 45a are respective suction pads. The details of the unit 45 are as follows.
As shown in FIGS. 3 to 14, a bearing 4 with the rotating shaft 45b of the unit attached to the end of the mounting rod 43
6, one end of a rotating lever 47 is fixed to the upper end of the rotating shaft, and a roller 48 is vertically disposed at the other end. Note that the lever 47
A crimping ring 50 is attached to the lower surface of the bearing 4, which tends to press against the lever 47 in the longitudinal direction under the action of a spring 49.
Bracket 5 having an arcuate surface welded to the back surface of 6
Press against the side edge of 1. However, the roller 48
As shown in FIGS. 10 and 12, a U-shaped rotating guide 52 is provided oppositely, and the contact pieces 52a and 52b at both ends of this guide are
When the rollers collide, the rotation lever 47 is configured to change its direction accordingly.

By the way, the traveling unit 37 is driven by an air cylinder 53 attached to the support column 35, while the lifting unit 3 equipped on the unit 37
9 is moved up and down by an air cylinder 40 installed between the lower surface of the unit and an arm 42. Further, a shock absorber 55 is attached to the end of the traveling area of the traveling unit 37.

The above is the configuration of the transfer device 3, and this transfer device is provided on the back side of the centering device 2 and the mask removing machine 4 attached thereto. The configuration of the mask removing machine 4 will be explained below.

The configuration of the mask removing machine 4 is as shown in FIGS. 15 to 18, in which a lifting board 61 is cantilevered against a guide frame 60 vertically installed on the back side of the frame 1.
It is attached via an elevating frame 62 shown at the left end of FIG. 15, and this elevating frame is moved up and down by an air cylinder 63. As shown in FIG. 16, the elevating board 61 has a cross shape when viewed from above, and a pawl and a seat setting mechanism, which will be described later, are mounted on this board. That is, a center post 64 is provided in the center of the board, and on this post there are installed upper and lower sets of a catch setting cam 65 and a catch drive pinion 66, as well as a claw setting cam 67 and a claw drive pinion 6.
8 (see Figure 15). As shown in FIG. 16, each of the setting cams 65 and 67 has four arcuate cam grooves 69 that converge toward the center, into which a guide roller 69' is loosely fitted. has been done. Then, seat moving links 70a, 70b and 7 which are pivotally connected at one end to this roller are provided.
1a and 71b are attached so that they are symmetrical in the top, bottom, left and right in the figure. These seat moving links are all attached with substantially the same configuration, and an example will be explained with reference to FIG. 17. As is clear from the figure, the other end of the link 70b is attached to the seat mounting bracket. 73, and this bracket is attached to the board 6.
Since it is slidably attached so as to straddle the slide rail 72 provided on the top surface of 1,
For example, when the link 70b is moved from side to side in FIG. 17 via the guide roller 69', the seat 74 of the panel mask attached to the bracket 73 will also move as shown by the chain line and solid line in the same figure. Move left and right. The other catch moving links 71a and 71b (links located on the left and right in FIG. 16) have almost the same configuration as shown in FIG. Therefore, when the seat is moved in the longitudinal direction, the seat mounting bracket 73 moves back and forth accordingly, and the seat 74 fixed to the bracket is moved.

Another pair of pawl moving links 75a, 75b and 76a, 76b are incorporated into the lower surface of each of the links 70a to 71b, and these also move to the disc-shaped pawl setting cam 67 in the same manner as above. Therefore, it is configured to reciprocate on the diameter line of the cam. A pawl mounting bracket 77 is attached to each of the links 75a to 76b, and a pawl 78 is individually fixed to each of the brackets. Therefore, when the cam 67 rotates, the pawl moving link also moves the cam 67.
7 along the diameter line, and the pawl 78 also moves accordingly.

By the way, a catch drive pinion 66 and a claw drive pinion 68 are mounted coaxially to the catch setting cam 65 and pawl setting cam 67, respectively, while maintaining a fixed relationship. As shown in FIG. 16, a catch drive rack 80 and a pawl drive rack 79 are engaged with each other, and each rack is provided with a catch drive cylinder 81.
a, 81b and a pawl drive cylinder 82 are attached. Incidentally, in the illustrated embodiment, two air cylinders 81a and 81b are connected in series and used as one seat drive cylinder, but this may be configured as a single cylinder.

The above is the configuration of the mask removing machine 4 for removing masks from panels, and a chain conveyor 6 is disposed on the top surface of this mask removing machine 4 to convey the removed masks (see Fig. 2). reference).
In the figure, reference numeral 7 denotes a drive pulley for the conveyor, and this pulley is driven by an electric motor 8.

<Operation and Effect> The operation and effect of the above embodiment will be explained below.

In FIG. 1, when a panel P fitted with a mask M is supplied onto a conveyor device C such as a belt conveyor or roller conveyor placed in front of a centering device 2, this panel mask P/
M is guided by a guide rod G provided on the conveyor and fed onto a top chain conveyor 5 attached to a centering device 2. As the top chain conveyor 5 is driven, the panel mask P/M moves at a constant speed to the center of the centering device 2, and when the front end of this panel mask blocks the light from the phototube switch PS shown in FIG. As a result, a signal is generated, and this signal causes the above-mentioned top encircle conveyor to stop, and at the same time, the air cylinder 23 is operated, and as shown in FIG. The moving frames 21a and 21b move toward the center via a link mechanism and grip the panel mask evenly from the short diameter direction. Next, the long-diameter air cylinder 22 located on the left side in FIG. 4 is operated, and the pair of left and right pushers, that is, the sliding frames 20a and 20b having the presser rollers 24 are moved inwardly through the link mechanism in the same manner as described above. Move along. In other words, the sliding frames 20a, 20b and 21a, 21b are freely supported on the guide rails 18, 19, 18', 19' in a vertically and horizontally symmetrical manner with the center post 12 as the center along with the short diameter side and the long diameter side. , and these sliding frames are connected to link plates 15a, 15b and 16 so that the same movement occurs with respect to each other.
Since they are connected by a and 16b, they move centripetally with the operation of the air cylinders 22 and 23 to center the panel mask P/M. In addition, in FIG. 4, the mounting piece 25 of the presser roller 24 provided on the right sliding frame 20b located on the long axis line is attached to the panel mask P/M as shown in FIG. 5 and FIGS. During the approach, that is, until the air cylinder 22 is activated, the panel mask is regulated by the cam follower 28 and lies down, so its advance is not hindered.On the other hand, when the air cylinder 22 is activated, the panel mask Since the restriction by the cam follower is released, the mounting piece 2
5 stands up like a rolypot. Thus, the presser roller 24 attached to the mounting piece 25 is
The panel mask P/M is gripped centripetally in cooperation with the presser roller 24 on the other sliding frame 20a.

The centripetal action (centering action) described above is exerted in the same way no matter how the dimensions of the supplied panel/mask change, so it can be widely applied to many types of panels with different dimensions. .

Then, as described above, a panel of a certain size
When the mask P/M is supplied to the center of the centering device 2 and then centripetally gripped by the presser roller 24 provided on the sliding frame, the stroke of the pistons in the air cylinders 22 and 23 (Extension distance) will also be determined according to the dimensions of the panel mask. That is, if the dimensions of the panel mask are small, the stroke of the air cylinder becomes long, and if the dimensions are large, the stroke becomes short. In response to such changes, the extension distance of the piston in the air cylinder can be determined using magnets (not shown) built into each cylinder and proximity switches KS, KS ₁ to _{KS 3} , etc. attached to the cylinder. The size of the supplied panel mask, ie, the size of the target pipe type, is determined by the detection. The signal detected as described above is sent to a catch drive cylinder 79 and a claw drive cylinder 82 in the mask removing machine 4 (to be described later), and the strokes thereof are adjusted to adjust the catch 74 and claw 78 properly. Set it in position.

By the way, when the panel mask P/M is gripped centripetally by the centering device 2 as described above, the detection signal causes the transfer device 3 shown in FIGS. The air cylinder 40 is actuated, and the suction units 44 and 45, which are provided so as to extend in front of the device, are lowered along the lifting post 38 from the position shown by the solid line in FIG. 44
The panel mask P/M is suctioned and gripped via a. Incidentally, when the air cylinder 40 reaches its lowest point, the centering device 2 releases the panel mask, while when the cylinder reaches its highest point,
Top box conveyor 5 on centering device 2
will start and a new panel will be displayed, which is the next target work.
Acts to accept a mask. The air cylinder 40 mentioned above is a so-called switch cylinder and performs the above-mentioned switch function.

Panel mask P/ by suction pad 44a
When the piston rod M is gripped, the piston rod of the air cylinder 40 rises as described above, and when it reaches the highest point, the air cylinder 53 for traveling is actuated by the detection signal, and the traveling unit 37 is activated. That is, the lifting unit 39 is moved in the lateral direction while being suspended. The traveling unit 39
moves from the position C to the position D in FIG. 10, the suction pad 44a
moves directly above the mask removing machine 4 while holding the panel mask P/M, and then, at this position, the lifting air cylinder 40 is operated again to lower the panel mask onto the mask removing machine 4. .
At this time, the receiving surface of the panel mask in the mask removing machine 4 has receiving seats 74 on all sides, as described later.
and the claws 78 are kept in their proper positions and are on standby, so that the panel mask supplied by the transfer device 3 is accurately fitted onto these seats and claws. That is, the air cylinders 22 and 23 attached to the centering device 2
The catch drive cylinders 81a, 81b and the claw drive air cylinder 82 in the mask removing machine 4 are operated with their strokes controlled by the dimension detection signal (tube type discrimination signal) issued by the proximity switch. do. To explain this point in detail below, in FIG. 16, the drive cylinder 81a is
and 81b are both on the retracting side, the travel distance of the seat drive rack 80 attached to this is the maximum, so the pinion 6 that meshes with the rack
The rotation angle of 6 is also the maximum. Therefore, the catch setting cam 65 provided coaxially with the pinion rotates significantly counterclockwise in FIG. 69' will be located. Each of the guide rollers 69' has a seat moving link 70a.
Since one end of the bracket 71b is attached, as the link moves, each seat on the bracket 73 fixed to the other end of the link is set in its position in a state where it is expanded to the outermost side. The dimensions thus set are the dimensions of the panel indicated by the symbol L in FIG. Symbol S in Figure 4
indicates the minimum dimension, and when the centering device shown in the figure detects this dimension, the detection signal is sent to the cylinder 81 for driving the catch in the mask removing machine 4.
a, 81b, whereby in this case both piston rods of said cylinder extend together, causing said seat setting cam 65 to rotate clockwise in FIG. As a result, the cam groove 69
The tip portions of the seat moving links 70a to 71b that are fitted in the center post 6 are guided by the cam grooves.
It will be located closest to 4. Therefore, the seat 74 attached to the link protrudes forward and stops, so that it waits at a position suitable for the minimum size panel.

On the other hand, when the seat 74 is placed on standby at an intermediate position between the maximum dimension and the minimum dimension, the operation is performed as follows. That is, when the proximity switches KS, KS ₁ to KS ₃ , etc. detect the dimension indicated by the symbol I in Fig. 4,
In this case, only the catch drive cylinder 81a of the mask removing machine 4 is activated by the detection signal, and the catch setting cam 65 is rotated clockwise in FIG. 16 to the middle position of the cam groove 69. The seat 74 is moved forward to a position that matches the dimensions.

By the way, as described above, when the catch seat 74 operates, the pawl 78 also operates in conjunction with it. Its mechanism is almost the same as the operating mechanism of the catch, except that the length of the cam groove formed in the claw setting cam 67 is slightly longer than that of the catch setting cam 65. The only two points are that there is only one air cylinder 82 connected to the pawl drive rack 79 for rotating the cam 67 via the pinion 68. As shown in FIG. 20, a spacing adjustment bolt 83 is installed between the bracket 73 to which the catch seat 74 is attached and the bracket 77 of the pawl 78, so adjust this bolt as described above. If both brackets are set at a predetermined distance, the distance between the panel catch 74 and the pawl 78 will always be constant, so when the catch 74 stops at the predetermined position, the pawl 78 will also move accordingly. It will stop and wait at a predetermined position.

Now, while the claw and the catch are waiting in the predetermined position as described above, the panel mask P/M that is still fitted together is supplied from above by the transfer device 3. Then, the peripheral edge of the panel P is fitted into the seat 74, and the claws 78 are press-fitted between the inner surface of the panel P and the leaf spring B, as shown in FIG. When the pawl driving air cylinder 82 is activated in this state, the four pawls 78 move toward the center and push the leaf springs inward, causing the springs to come off the pins A, causing the panel P and the mask M The engagement relationship with is released.

That is, as shown in FIG. 16 as an example, the claws 78 are provided at four locations on the four circumferences of the mask receiving surface, so that all the pin engagement locations of the panel and mask shown in FIG. 21 are separated at the same time. It is.

Incidentally, while the claws 78 and the catch seats 74 are waiting at their respective predetermined positions as described above, the entire mask removing machine 4 to which these claws and the catch seats are attached cannot be raised or lowered as shown in FIG. It is raised via a frame 62 and a lifting air cylinder 63.
Therefore, the claws and the seat protrude upwards from the conveying surface of the chain conveyor 6 disposed on the upper surface of the mask removing machine 4. Therefore, no problem occurs for the mask removing machine 4 to accept the panel mask P/M supplied from above by the transfer device 3. Note that when the mask M fitted into the inner surface of the panel is removed as described later, the transfer device waiting above is activated by the signal, that is, the plate spring compression completion signal of the claw drive cylinder 82. The suction unit 45 of No. 3 adsorbs the panel P and rises, the pawl 78 opens in response to this ascent completion signal, and then the elevating frame 62 to which the pawl 78 is attached is lowered by the air cylinder 63. . Since only the mask M removed from the panel P is placed on the chain conveyor 6, this mask is successively discharged from the machine by the conveyor.

The above is the operating state of the mask removing machine 4, and while the mask is being removed from the panel, the transfer device 3 operates as follows. In Figures 10 to 12, the suction pad 4 attached to the right side of the device
4a is for sucking the panel mask P/M centripetally gripped by the centering device 2, lifting it upward, and supplying it to the center of the upper surface of the adjacent mask removing machine 4. , as already stated. When the suction pad 44a in the transfer device finishes supplying the panel mask P/M to the mask removal machine, the suction pad 44a immediately releases the suction state and rises, and then the traveling unit 3
The suction pad 44a is sent back by the air cylinder 53 connected to the centering device 7, and the suction pad 44a is moved directly above the centering device 2 again. In other words, traveling unit 3
7 returns from the position D to the position C in FIG. At the same time, the suction pad 45a also suctions and grips only the panel P placed on the mask removing machine 4 from which the mask M has been removed.

The suction units 44 and 45 that suction-hold the panel mask P/M and the panel P in this way are
After ascending, it again moves towards the left in Figure 10,
When the traveling unit reaches position D, it descends again and the suction state is released. In such a case, the panel mask P/M and the panel P will be released from each of the units 44 and 45, but at that time, the 10th
The suction unit 45 located on the left side in the drawings and FIG. 12 rotates 1/4 turn in the following manner to change the orientation of the panel P to which it is suctioned by 90 degrees. That is, as shown in both figures, a rotating lever 47 is fixed to the top of the suction unit 45, and this lever is connected to a U-shaped rotating guide 52 via a roller 48.
The lever 47 is configured to collide with the contact pieces 52a and 52b of the lever 47, and since the contact pieces are provided at positions separated from each other by 1/2 of the distance between C and D on the left and right with the position D as the center, the lever 47 As it moves to the left, the roller 48 provided at the upper end of the lever collides with one of the contact pieces 52a, and the travel unit 37 moves further while remaining in collision. Therefore, the rotating lever 47
is rotated clockwise as shown by the chain line in FIG. 12 to rotate the shaft 45b of the suction unit 45 by 1/4, thereby changing the direction of the panel P that is suctioned thereon.

Note that when the suction unit 45 moves in the opposite direction after releasing the panel P, the lever 47 collides with the other contact piece 52b and rotates 1/4 in the opposite direction in the same manner as above, returning to its original state. It returns to its position.

The above is the operation of the device for separating fitted articles according to the present invention. In the above embodiment, a case was described in which the panel and the mask were engaged with pins at four points on the four circumferences, but it is also possible to implement the case with three pins or two pins. Also, air cylinders are used to drive centering devices, etc.
It is also possible to use an appropriate power source such as a hydraulic cylinder or an electric cylinder instead of the air cylinder. Furthermore, although two cylinders are used to set the position of the catch seat 74, this can also be done with one cylinder, or various configurations such as an intermediate stop type cylinder or an electric cylinder can be used. You can take it.

In order to detect the dimensions of the supplied article (panel mask in the illustrated example), the above embodiment uses a cylinder equipped with a proximity switch, but it is also possible to attach a separate detector to detect the dimensions or position. Of course, it is possible. Although a conveyor is used to carry in or carry out the panel mask, a traverser may be used instead of this conveyor.

<Features> Since the present invention has the above-described configuration and operation, even if the dimensions of the target article vary, it can be processed accordingly, and it is not necessary to use a separating device for each target article as in the past. There is no need to prepare.

In addition, at the same time as the centering device grips the object, the detection signal activates the separating device to position the catch and claw for separating the object, so the positioning operation can be performed twice. Significant labor savings can be achieved compared to the conventional type. In addition, according to the conventional type, when removing the mask from the panel, a separate mechanism was required to stop the rotation of the mask when compressing the engagement spring.
According to the present invention, since the plate spring is compressed while holding the panel through the catch, there is no risk that the mask will rotate, and therefore there is no need to provide a rotation stopping mechanism.

Also, at the same time as centering the panel mask,
Since the tube type signal can be output, it is possible to automatically process several types of panel masks with different shapes with one device.

Furthermore, according to the present invention, the panel/mask centripetally gripped by the centering device can be immediately transferred onto the mask removal machine via the transfer device, thereby making it possible to shorten the time cycle. .
