Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching method and a punching apparatus, and more particularly to a punching method and a punching apparatus for punching a product having a predetermined shape from a material sheet by using a flat die having a blade die formed on one surface of a flat substrate.

[0002]

2. Description of the Related Art Conventionally, when a large number of products such as cards are punched from a raw paper, a punching machine of a press type has been conventionally used. In this case, since a simple flat mold in which a strip-shaped blade is planted in a rectangular ring shape can be used, the mold cost is low. Therefore, it is particularly effective for punching a wide variety of products.

However, in this press-type punching machine, the entire area of the blade die forming surface (KC) is pressed against the material sheet at the same time, and therefore the pressing force required for punching is large. Further, in order to allow the product and the scrap to be taken out from the punching section after the completion of the punching, a joint (J) is required between the product (A) and the scrap (S) as shown in FIG. Further, after the punching is completed, it is necessary to cut the joint (J) to separate the product (A) and the scrap (S).

To reduce the punching pressure force out of these problems, the type shown in FIG. 2 can be adopted.
This one consists of a flat type (K) that is driven in the horizontal direction and a half cylinder press (PS) with an arcuate cross section that is in contact with the blade type forming surface (KC) of this upper surface. Clamp the material paper (W) at the end of the
(PS) and flat mold (K) are driven synchronously, the material paper (W) is pinched between the half cylinder press (PS) and flat mold (K), and the half cylinder press (PS) Since the product (A) and (A) are punched in such a manner that the product is pressed against the material paper (W) in a rolling contact state, the pressing force required for the punching process is significantly reduced.

However, even in the case of this type, the product (A) (A)
The product (A) (A) cannot be taken out from the upper surface of the flat mold (K) unless the joint (J) (J) is provided between the scrap (S) and the scrap (S). ) (A) and scrap (S) must be separated. Also, when punching, the outer peripheral surface of the half cylinder press (PS) is
Since it is pressed by (W), the flat mold (K) having a length larger than the circumferential length of the arc-shaped cross section of the half cylinder press (PS) cannot be used. In other words, there are restrictions on the size of the material paper (W) and flat mold (K) that can be supported by the size of the half cylinder press (PS).

The present invention has been made in view of such a point, and "presses the material paper (W) against the blade forming surface (KC) of one side of the flat plate-shaped flat (K), In this method or device for punching a product (A) (A) of a predetermined shape from the material paper (W), without providing a joint (J) (J) between the product (A) and the scrap (S). The task is to be able to punch through and to be compatible with various sizes of flat type (K).

[Invention of Claim 1]

[0008]

[Technical Means] The technical means of the method of the present invention taken to solve the above-mentioned problem is that "each blade die (11) of the blade die forming surface (KC) formed on the lower surface of the flat die (K) is While being composed of continuous blades in an endless loop shape, the lower roll (2b) having a circular cross section is brought into contact with the blade mold forming surface (KC) from below, and the lower roll and the flat mold (K) The material paper (W) is pinched between them, and the flat roll (K) is horizontally moved while rotating the lower roll (2b), so that the nipping position of the material paper (W) is sequentially moved to the product.
I tried to punch out (A) and (A). " Here, the material paper (W) may be a rectangular paper of a certain size or a long strip paper.

[0009]

The above technical means operates as follows. Lower roll
By horizontally moving the flat mold (K) while rotating (2b), the position where the raw paper (W) is pinched moves sequentially and the product (A)
It is similar to the conventional half cylinder press type in that (A) is punched, but the lower roll (2
Since b) has a circular cross section, it is in principle long and infinitely long.
It will be applicable to (K).

Further, since each blade die (11) of the blade die forming surface (KC) is composed of blades which are continuous in an endless loop shape, the material formed by the lower roll (2b) and the flat die (K) is used. When the product (A) (A) is punched by sequentially moving the clamping position of the paper (W), the raw paper (W) is completely separated into scrap (S) and product (A) (A). To be done. At this time, place the lower roll (2b)
Since it is to be brought into contact with the blade forming surface (KC) formed on the lower surface of (K), the products (A) and (A) drop downward at a position beyond the lower roll (2b). On the other hand, scrap (S) is the lower roll (2b)
It is sandwiched between the flat type (K) and the flat type (K), and the punching operation proceeds in this state.

The rear end of the flat type (K) has a lower roll (2
The punching is completed by moving from b) to the front. After that, when the scrap (S) is removed and the flat mold (K) is returned to the initial position, each part returns to the initial state. When returning the flat mold (K) to the initial position, if the lower roll (2b) is moved down from the blade mold forming surface (KC), the flat mold (K) can be smoothly returned.

After that, when the series of operations described above is executed,
Products (A) and (A) are punched out from new material paper (W).

[0013]

[Effect] Since the punched products (A) and (A) are separated from the scrap (S) and fall below the flat mold (K), the products (A) and (A)
And scrap (S) can be taken out separately. Further, it is not necessary to separate the product (A) (A) from the scrap (S) after punching. The lower roll (2b) may be a roll having a circular cross section, and it is not necessary to form a special cross section such as the half cylinder press (PS) shown in FIG.

Since the lower roll (2b) is a cylindrical body, it has a flat shape.
There is no restriction on the length of the moving direction of (K). [Invention of Claim 4]

[0015]

The invention of claim 4 relates to an apparatus for carrying out the invention of claim 1 and solves the same problem. The technical means adopted for this purpose is that "a flat mold (K) whose lower surface is a blade mold forming surface (KC) is attached to the lower surface of a mold holding plate (13) provided for reciprocal horizontal movement, A rotatable upper roll (2a) that contacts the holding plate (13) from above and a blade upper surface (KC) of the flat mold (K) that contacts from below and is driven to rotate by a drive unit. The lower roll (2b) is provided, and the blade mold forming surface (KC) of the flat mold (K) and the lower roll
The material paper (W) is pinched between it and (2b). "

[0016]

[Operation / Effect] With this technical means, the mold holding plate (13) equipped with the flat mold (K) is provided for reciprocal horizontal movement, and the rotatable upper roll (2a) is Since it is in contact with the mold holding plate (13) from above, a flat mold (K)
Of the lower roll (2
When b) is rotationally driven, the blade mold forming surface (KC) of the flat mold (K) and the lower roll (2b) are in rolling contact with each other. Then, the material paper (W) attached to the blade mold forming surface (KC) of the flat mold (K) is the upper roll (2a).
The blade mold forming surface (K) is pressed by the sandwiching force between the lower roll (2b) and the lower roll (2b), and the method of the invention described in claim 1 is performed with the rotation of the lower roll (2b).

At the time of this punching, the die holding plate (13) and the flat die (K) attached to the lower surface of the die holding plate (13) are opposed to each other in the upper roll (2
Since it is pinched by a) and the lower roll (2b), the mold holding plate
Even if the rigidity of (13) or flat type (K) is insufficient, the pressing force for punching can be increased. That is, the punching device as a whole can be reduced in weight. [Other Inventions] The following improvements and the like can be adopted in the above-described invention.

In the case where a hard elastic material coating layer is formed on the surface of the lower roll (2b) and the blade of the blade die forming surface (KC) bites into the hard elastic material coating layer, the blade die forming surface ( Even if the plane of the blade edge of (KC) is not an accurate plane, punching failure does not occur. Even if the lower roll (2b) has a configuration in which the belt (V) made of hard elastic material is wound between the pressure roll (20) and the side roll parallel to this in a tensioned state, the same effect can be obtained. There is.

When the flat die (K) is of a type in which a punching blade die (11) is implanted in a substrate and an elastic release material such as a sponge is provided on the inner and outer circumferences of the blade die (11), After punching, the products (A) and (A) easily separate from the blade mold forming surface (KC). Also,
"The material paper (W) is a long strip of paper, and the mold holding plate (13)
Makes it possible to reciprocate between the initial position where its front end substantially coincides with the lower roll (2b) and the most advanced final position, and when the mold holding plate (13) coincides with the final position, the lower roll (2b ) Is separated from the flat mold (K), and the lower roll (2b) is brought into contact with the blade mold forming surface (KC) of the flat mold (K) with the mold holding plate (13) returned to the initial position. A roll driving device (101) and a return drive device that drives the die holding plate (13) to return to the initial position in a state where the die holding plate (13) coincides with the final position and the lower roll (2b) is lowered ( 102) and a paper feeding device (103) for feeding the material paper (W) into a predetermined position below the blade forming surface (KC) of the flat mold (K) when the lower roll (2b) is in the lowered state. Let me
In this case, the flat die (K) attached to the die holding plate (13) automatically returns to the initial position after the punching is completed, and then the blank paper (W) is sequentially loaded into the punching section to perform the punching. A series of required operations can be automated. (See FIG. 3) Further, in the present invention, "the paper feeding device (103) is a suction device (which adsorbs and holds the front end of the material paper (W) by projecting rearward from the rear end of the die holding plate (13) ( 42), so that the material paper (W) is adsorbed when the mold holding plate (13) is in the initial position and the material paper (W) is released when the mold holding plate (13) is in the final position. Adsorption device (4
2) Control device (104) for controlling the adsorption device
In the invention, the release position of the raw material paper (W) by (42) is set forward of the initial position of the flat mold (K) ''. In the invention, the material paper (W) of a certain size is sequentially inserted into the punching position each time the punching is completed. In this case, the accuracy of the paper feeding position is improved and the structure of the paper feeding device can be simplified. (Refer to FIG. 4) The paper feeding device (103) is arranged so as to interpose the strip-shaped raw material paper (W) between the blade forming surface (KC) of the flat mold (K) and the lower roll (2b). 2b) and the flat type (K), the material paper (W) is kept in a stopped state when the sandwiching pressure disappears '', in the invention of the form, the long strip-shaped material paper (W) is transferred to the product (A) (A This punching operation proceeds smoothly when punching) continuously. In this case, it is necessary to return the flat mold (K) to the initial position in a state where the lower roll (2b) is separated and lowered from the flat mold (K) after completion of the punching operation in one step.

When the lower roll drive system is a system in which the surface of the auxiliary roll (2c) which is driven to rotate is brought into contact with the surface of the lower roll (2b) to drive the lower roll (2b), Even if the diameter of the lower roll (2b) changes due to abrasion of the like, as long as the circumferential side of the surface of the auxiliary roll (2c) is maintained constant, the circumferential degree of the surface of the lower roll (2b) does not change, Punching accuracy is stable over a long period of time.

It is a punching device. In addition, the tooth forming surface of the flat die (K) has a rectangular annular blade die whose number corresponds to the number of cards.
(11) (11) is planted. Also, this blade type (1
The cutting edge of 1) is continuous in a loop shape and does not have a discontinuous portion as in the past.

Hereinafter, each part of this apparatus will be described in detail. [Punching main part] As shown in Fig. 5, the flat type (K) has a rectangular ring-shaped blade die (11) (11) arranged in a matrix on a wooden board substrate (10) to form a strip-shaped blade. Bend into a rectangular ring and butt the ends together to make each blade die (11).

No sponge layer is provided on the outer periphery of 1). In addition, this blade type
(11) The sponge layer (12a) is left in the area surrounded by (11).

Since the flat type (K) is used, as shown in FIGS.
As shown in 7, the upper and lower parts of the frame (F) are placed facing each other.
The flat roll between the placed upper roll (2a) and lower roll (2b)
The mold holding plate (13) that holds (K) is supported horizontally
Has been. The left and right sides of the mold holding plate (13) are flared.
Installed on the rails (R) (R) on the opposite side walls of the
It is fixed to the moving body (14) (14). Also, after punching is completed
At this time, the mold holding plate (13) was driven to return to the initial position.
Driven by the rotary actuator (RD)
Drive side sprocket (P₁) And the free on the other side of this
Sprocket (P ₂) And these sprockets and mold holding plates
(13) A horizontal drive (H
D) is deployed. Claim this horizontal drive (HD)
It functions as the return drive device (102) described in the above range.

A _one- way clutch (C) is interposed between the output shaft of the rotary reactor (RD) and the drive sprocket (P ₁ ), and the horizontal drive device (HD) includes a die holding plate (1).
It is free in the forward direction of 3). After the mold holding plate (13) has moved to the final position, the mold holding plate (13) is driven to return from the final position (advance position) to the initial position by the operation of the rotary reactor (RD).

The upper roll (2a) makes rolling contact with the upper surface of the mold holding plate (13). The lower roll (2b) provided below the upper roll (2a) is larger than the upper roll (2a), and the outer peripheral surface is covered with the urethane rubber layer (21). And
The lower roll (2b) is rotatably supported by bearings (22) and (22) at the upper end of the lifting device, the shafts of both ends of which are built into the side wall of the frame (F).

The bearings (22), (22) are held in the side walls of the frame (F) so as to be vertically paired with each other. An elevating frame (23) which is provided below each bearing (22) and which similarly goes up and down with respect to the frame (F) is an adjusting screw.
Connected by (24). The lifting frame (23) is connected to both ends of the input shaft (25) by a crank mechanism (26), and the input shaft (25) is interlocked with a reversible motor (27) having a reduction gear. The crank mechanism (26) is eccentric shaft (26a) that rotates integrally with the input shaft (25), and is rotatably externally fitted to the eccentric shaft (26a) and swingably connected to the elevating frame (23). It consists of an arm (26b).

Therefore, when the input shaft (25) is rotationally driven by the reversible motor (27), the elevating frame (23) is vertically moved within the range from the top dead center to the bottom dead center of the eccentric shaft (26a), The bearing (22) connected to this is integrally moved up and down. Moreover, since the common input shaft (25) drives the crank mechanisms (26) (26) on both sides, the bearing portions on both sides of the lower roll (2b) are synchronously moved up and down by the same stroke.

In this lifting device, the position of the top dead center of the lower roll (2b) can be adjusted. For this reason, a worm wheel (31) integrated with the adjusting screw (24) and a worm (32) that meshes with the worm wheel (31) are provided in the lifting frame (23), and the lifting frame (31) built into the opposite side wall of the frame (F) ( The worms (32) and (32) of 23 and (23) are integrally connected by a connecting shaft (33). And
A handle (34) is provided at one end of the connecting shaft (33),
This rotation operation causes the adjusting screw (24) to rotate, whereby the screwing degree of the adjusting screw (24) into the bearing (22) changes, and the top dead center of the lower roll (2b) can be adjusted.

Lower roll (2b) on the side wall of the frame (F)
The penetrating portion of both end shaft portions and the penetrating portion of the connecting shaft (33) are long holes that are long in the vertical direction so that they can move up and down by a constant stroke. Further, a servo motor (28) is attached to one bearing (22) in order to drive the lower roll (2b) to rotate. In the punching main part detailed above, the flat type (K) of FIG.
As shown in FIG. 7, with the clamp fittings (15) and (15) additionally attached to the lower surface of the mold holding plate (13), the mold holding plate (13) is set to the initial position, as shown in FIG. In addition, on the positioning stopper (16) provided at the front end of the mold holding plate (13), the material paper (W)
The flat type (K) and the material paper (W) are positioned by abutting the tip of the, and the blade types (11) and (11) of the flat type (K) match the design applied to the material paper (W). . In this state, the reversible motor (27) is rotated in the forward direction to drive the input shaft (25) in the forward direction, and the lower roll (2b) is lifted so that the blade tips of the blade dies (11) and (11) are placed on the urethane rubber layer (21). Let it bite. By adjusting the top dead center position of the lower roll (2b) by operating the handle (34), it is possible to optimize the degree of cutting of the blade tip of the blade molds (11) (11) into the urethane rubber layer (21). Next, when the servo motor (28) is driven to drive the lower roll (2b) in the normal direction, as shown in FIGS. 8 and 9, the material paper (W), the flat mold (K), and the mold holding plate (13). Has an upper roll (2a) and a lower roll (2b)
The blade die (11) moves horizontally while being clamped between and, and when the products (A) and (A) are sequentially punched and passed through the lower roll (2b).
The products (A) and (A) in (11) are pushed downward by the sponge layer (12a). At this time, the sponge layer (1) in the blade mold (11) (11)
Since the surface of 2a) protrudes below the sponge layer (12b) around the edges of the blade molds (11) and (11), products (A) and (A) are scrap.
It will be pushed below (S). On the other hand, flat type
Since the sponge layer is not provided on the outer periphery of the blade dies (11) (11) at the front end of (K), the scrap (S) is the outer periphery of the blade dies (11) (11) in the first row in the front. It is held in a temporarily fixed state while biting into.

In this state, the products (A) and (A) are sequentially punched out and the flat mold (K) is advanced together with the mold holding plate (13) to the final position, and the reversible motor (27) moves the input shaft (25). The lower roll (2b) is driven downward by a predetermined angle and the blade dies (11) and (11) are separated from the lower roll (2b). In this state, the rotary actuator (R
Sprocket (P ₁ ) is driven by D) and chain (Y)
The mold holding plate (13) is driven to return to the initial position by interlocking with.

As described above, the playing cards as the products (A) and (A) are punched, but in the first embodiment, the following devices are added. [Paper feeding device] As shown in FIG. 6, this device includes a stock table (41) for material sheets (W) (W) arranged below a die holding plate (13) at an initial position and the die. Adsorption device (42) behind the holding plate (13) that adsorbs only one uppermost material sheet (W) stacked on the stock table (41), and drives this adsorption device before and after a certain stroke. The air cylinder (46) and the pair of feeding devices (5) (5) that feed the material paper (W) fed by them between the lower roll (2b) and the flat mold (K). The feeding devices are arranged in mutually symmetrical positions on the inner surfaces of the opposite side walls of the frame (F).

As shown in FIG. 6, the adsorption device (42) is
A swing lever equipped with a suction cup is swung at a predetermined timing by a drive device (43), and a movable bracket (44) to which these are attached is installed between a pair of guide shafts (45) (45). The movable bracket is driven back and forth by the air cylinder (46). In addition, the suction operation by the suction cup is the driving device.
(43) and the operation of the air cylinder (46). With these configurations, the uppermost material sheet (W) is attracted to the suction cup, and the rear end of the material sheet (W) is lifted by the operation of the drive unit (43) .In this state, the air cylinder (46)
Is activated and the uppermost material sheet (W) is transported forward by a constant stroke. The stock table (41) on which the stacked material sheets (W) (W) are placed is configured to be lifted by a certain stroke when the transfer of a certain number of material sheets (W) (W) is completed, The uppermost material paper (W) is always set to a height within a predetermined range.

Next, each feeding device (5) has a pulley (51).
It consists of a belt (52) hung between (51) and a pressure roll (53) that is in contact with this belt, and the running locus of the belt (52) is inclined toward the top of the lower roll (2b). On pulleys (51)
(51) is arranged, and the extension line of the running locus of the belt (52) coincides with the stopper (16) of the mold holding plate (13) in the initial position. On the other hand, the pressure roll (53) has a structure in which a free roll is pivotally supported by the tip of the swing lever, and the pressure roll (53) is lightly pressed against the upper surface of the belt (52) by its own weight. The lower pulley (51) is driven, and the belt (52) is driven to run in the direction of the arrow in the figure. Further, the position of the boundary between the lower pulley (51) and the upper pressure roll (53) is determined by the material paper (W) placed on the stock table (41).
It is set on the extension line of the uppermost material paper (W) of (W).

Therefore, when the uppermost material sheet (W) is pushed forward by the suction device (42) described above, the leading edge of the material sheet (W) is placed between the pressure roll (53) and the belt (52). Part is inserted, and at this point, the suction by the suction cup of the suction device (42) is released and both sides of the material paper (W) are moved by the running of the belt (52) and the pressure of the pressure roll (53) to the lower roll ( 2b) and the flat type (K), and the leading edge of the raw paper (W) is stopped by the stopper (16).
Hit Since the pressure roller (53) is only lightly pressed against the upper surface of the belt (52) by its own weight, the belt (52) slips and the movement of the material paper (W) is prevented in this state. After this, as described above, the lower roll (2b) is lifted and the punching operation proceeds. The pulley (51) may be always driven, but the pulley (51) is started when the material paper (W) is sent out by the suction device (42) at the timing of the operation of the suction device (42). Let the material paper (W)
The drive of the pulley (51) may be stopped at the time when the tip of the pulley hits the stopper (16).

[Product Laminating Device] In this embodiment, a playing card as a product (A) (A) is punched from a material paper (W) on which patterns corresponding to each card are printed in a predetermined order over four lines. . The design of the material paper (W) shown in FIG. 10 is set such that the rear end of the leftmost row is located in the topmost layer in the product stacking state, and the design in front of this is superposed below it. . The symbols in each row are arranged in the same order as described above, and the group of playing cards on the right is superposed on the lower layer of the group of playing cards on the left.

In front of the lower roll (2b), as shown in FIG.
It comes into contact with the surface of this and tilts forward and downward and the lower roll (2b)
A chute (61) having a width substantially matching the width direction of the product is provided, and a product stock box (6) is continuously connected to the front end of the chute (6) so as to open upward. The upper end of the rear side wall of this product stock box (6) is continuous with the front end (lower end) of the chute (61), and the distance from the front side wall is smaller than the front-rear length of the product (A) (A). Is set to a large value. The bottom surface is an inclined surface that inclines downward toward the front as a whole. Further, as shown in FIG. 11, the product discharge side of the product stock box (6) is open, and the side wall (62) is inclined so as to face the right side in the figure, and the product stock box (6) rises from left to right. Four saw blade-shaped recesses (6a) to (6d) composed of an inclined bottom surface (63) are continuously formed. The bottom of this product stock box (6) is shown in Figure 10.
A pair of grooves extending to the left and right as shown in (64) (64)
Run parallel to each other, and the fork (65) equipped with a pair of shafts inserted into the groove is connected to the output part of the reciprocating linear drive device (66).
It is linked to (67). The fork (65) is moved to the product stock box by the operation of the output section (67) at a predetermined timing.
Reciprocate from the left end of (6) to the right open part. In addition, a conveyor device (68) for sending out the laminated product is continuously provided at the open part at the right end of the product stock box (6).

The above operation of the product laminating apparatus is linked with the punching operation. This point will be described below. When the lower roll (2b) rotates in contact with the blade mold forming surface (KC) on the lower surface of the flat mold (K) as shown in Fig. 8 and Fig. 9, the material paper (W) becomes product (A) (A). The card of No. 1 is punched out, and the cards dropped from the flat mold (K) fall into the product stock box (6) along the chute (61) in four rows. As shown in Fig. 10, the width of this product stock box (6) is almost the same as that of the lower roll (2b),
At the bottom of this product stock box (6), four saw blade-shaped recesses (6a) to (6d) are continuous, and these are 4 of the material paper (W).
Since it matches the arrangement interval of the pattern of the row, the playing cards of each row printed on the material paper (W) are separately accommodated in the recesses, and in each recess, the card in the front row of each row is the lowest layer. When the card is positioned and the succeeding card is stacked on top of it, and when the blanking of the entire area of the material paper (W) is completed, the card in the last row is stacked on the uppermost layer.

After this, the fork (65) is the product stock box.
It is moved from the left end of (6) to the right end. As a result, the card groups punched from the respective rows of the material paper (W) and stacked in the respective recesses are sequentially stacked. At this time, since the inclined bottom surface (63) of each recess is an inclined surface that rises in the moving direction of the fork (65), the card group on the left side is located above the card group on the right side in FIG. It is surely superposed.

Then, when the fork (65) is moved to the final position at the right end, the four card groups are integrally stacked, and the stacking order is a predetermined proper order. In this embodiment, the material paper (W) is set so that the printing surface of the material paper (W) and the planting portion of the flat mold (K) blade molds (11) (11) face each other. Therefore, the conveyor device (6
The laminated product taken out in 8) is laminated with the design on the top.

A) Insert the pair of arms (73) (73) that are inserted into the opening (SK) of the scrap (S) after punched out so that they are diagonally upward from both sides of the cross rail (74) and symmetrical to each other. It consists of a scrap hanger that protrudes to the inside.

In the scrap hanger, as shown in FIG. 12, the horizontal bar (74) is connected to the upper end of the main shaft (75) rotatable with respect to the base (B), and one pair of arms (73) is provided. (73) is always set so that it faces the scrap guide (71). In this product, as the punching progresses, the scrap (S) is forcibly fitted to the outer periphery of the blade mold (11) (11) in the front row of the flat mold (K) and the rear region is sponge-shaped. Scrap guide extruded from blade form (11) (11) by layer (12)
Move while being supported by (71). Then, the mold holding plate (1
When all of the flat type (K) fixed and attached to 3) protrudes completely forward from the lower roll (2b) and all the products (A) and (A) are punched out from the raw paper (W), The front edge of the scrap (S) fitted in the molds (11) (11) is clamped in conformity with the clamp devices (72) (72). On the other hand, the rear end of the scrap (S) is supported by the front end of the scrap guide (71).

After this, the clamp devices (72) (72) swing forward and downward from the horizontal posture to scrap (S) and the blade molds (11) (11).
As soon as the scrap (S) is disengaged, the scrap (S) is moved forward by a constant stroke and the scrap (S) disengages from the front end of the scrap guide (71), causing the entire scrap (S) to hang downward. Rotate in the direction. During this time, the opening (SK) of the scrap (S) protrudes in place at the arm (73) (7
It fits into 3) and the scrap (S) is suspended by these pairs of arms. Moreover, since this arm rises toward the tip, each time a scrap (S) is thrown in, these arms
(73) It will be hung from the base end part of (73) in the state which overlaps one by one. When the scrap (S) (S) suspended on the pair of arms (73) (73) is full, the main shaft (75) is rotated to scrap the other pair of arms (73) (73). (S) Project into the locus of descending swing. Then, when the scraps (S) (S) suspended in this state are pulled out from the arms (73) (73), the scraps (S) (S) can be taken out in a stacked state. At this time, the operation of binding the grid-shaped scrap (S) is also easy.

The scrap guide (71) described in this section also has the function of separating the product (A) (A) and the scrap (S) at the time of punching. To ensure this effect, attach the rear end of the scrap guide (71) to the product of the lower roll (2b).

[Surface Regenerating Device for Lower Roll (2b)] In this embodiment, the surface of the lower roll (2b) is covered with a urethane rubber layer (21), and a flat die (K) blade die (11) Since the (11) is punched so as to bite, the surface of the urethane rubber layer (21) is scratched by the blade mold (11) during punching. In order to remove the scratches and traces and regenerate the surface of the urethane rubber layer (21), a feed screw parallel to the lower roll (2b) should be provided near the lower roll (2b) as shown in FIGS. 6 and 14. A (81) and a guide shaft (82) are provided, and these are installed between opposing side walls of the frame (F). A finishing cutting tool (80) equipped with a rotary blade (84) is supported on a moving table (83) which is paired with the feed screw and fitted with the guide shaft. This Finishing Cutting Tool (80)
The supporting position of the is changed up and down, the rotating blade (84) contacts the surface of the lower roll (2b) when the finishing cutting tool (80) is lifted, and the lower roll (2b ) Away from the surface.

Therefore, as shown in FIG. 14, while lifting the finishing cutting tool (80) and rotating the lower roll (2b) with the rotary blade (84) in contact with the surface of the lower roll (2b), When the feed screw (81) is driven to rotate at a predetermined speed, the moving base (83) will move along the surface of the lower roll (2b).
The scratches and traces on the surface of (2b) are removed and a smooth surface is regenerated. Here, it is needless to say that the traveling number and traveling speed of the movable table (83) and the relationship between these and the rotation speed of the lower roll (2b) are set in advance. Return the (83) to the initial position and finish the cutting tool (8

In order to reciprocally drive the die holding plate (13) by the rotation of the motor (9), an oscillating gear (93) that is transmitted to the output shaft (91) of the motor (9) through a crank mechanism is provided. To be Oscillating gear
When the crank (91a) attached to the output shaft (91) rotates, the slider (93) reciprocates with respect to the pair of shafts provided on the oscillating gear (93) as shown in FIG. By sliding, the oscillating gear (93) reciprocally rotates about the fulcrum shaft (93b). The mold holding plate (13) is reciprocally driven by a horizontal drive device (HD) that is transmitted to an intermediate gear (94) that meshes with the oscillating gear. The horizontal drive unit (HD) has the same configuration as that of the first embodiment,
A chain (Y) interposed between the sprockets (P ₁ ) and (P ₂ ) is connected to both sides of the mold holding plate (13). Therefore, FIG.
When the oscillating gear (93) is driven in the direction of the solid line arrow in the figure, the mold holding plate (13) is driven to the left side in the figure, that is, to the front by the interlocking relationship with the horizontal drive device (HD). To be done. Conversely, when the oscillating gear (93) is driven in the direction of the arrow indicated by the broken line, the die holding plate (13) is moved back to the right side in the figure.

Both ends of the upper roll (2a) and the lower roll (2b) are supported by swinging arms (95) (95), and the swinging arm (95) that pivotally supports the lower roll (2b). The swing fulcrum (95a) of () is located on the opposite side of the cam (92), that is, in front of the lower roll (2b). On the other hand, the swing fulcrum (96a) of the swing arm (96) of the upper roll (2a) is located rearward of the upper roll (2a), that is, on the opposite side of the swing fulcrum (95a). To do. The free end of the swing arm (95) that protrudes forward from the swing fulcrum (95a) and the free end side of the swing arm (96) are connected by a link (97). Both ends of this link are rotatably connected to each swing arm, and when the input end (98) facing the cam (92) is lifted, the free end of the swing arm (96) is pulled down. To be In other words, the rotation of the cam (92) causes the upper roll
The (2a) and the lower roll (2b) face each other or move away from each other.

In this embodiment, as shown in FIG.
When the lower roll (2b) is lifted by the rotation of the cam (92), its flat surface is attached to the mold holding plate (13).
The blade mold forming surface (KC) of (K) is set such that the blade molds (11) and (11) slightly bite into the lower roll (2b). At this time, the upper roll (2a) is connected to the link (97) by the die holding plate.
It is set to face (13).

The swing arms (95) (96), the swing gear (93),
As shown in FIG. 18, the cam (92), the link (97), the horizontal drive device (HD), etc. are separately provided in the mechanism chambers (90) (90) provided on both side walls of the frame (F). Built in. Upper roll (2a)
The lower roll (2b) is supported at both ends, and the swing fulcrum axes of the left and right swing arms that support these are common. The left and right horizontal drive (HD) (HD) sprockets (P ₁ ) (P ₁ ) shafts and the sprocket (P ₂ ) (P ₂ ) shafts are connected together.

In this embodiment, as the lower roll driving mechanism, the driving roll (2c) which is in contact with the surface of the lower roll (2b).
And a pair of rocking levers (R) (R) that support both ends of the drive roll (2c) and an air cylinder (E) that rocks the rocking lever (R). With this combination, when the output shaft of the air cylinder (E) is advanced and the tip side of the rocking levers (R) (R) is rotated to the lower roll (2b) side, the surface of the drive roll (2c) is lowered. The lower roll (2b) is pressed against the surface of the roll (2b) and is rotated by friction transmission with the surface of the drive roll (2c). Therefore, the circumferential degree of the lower roll (2b) matches that of the drive roll (2c), and the traces and scratches caused by the blade mold (11) on the surface of the lower roll (2b) are removed to regenerate the surface. By doing so, even if the diameter of the lower roll (2b) changes, its circumferential degree is maintained constant.

Further, in this embodiment, FIG. 15 and FIG.
As shown in FIG. 9, a suction device (42) for loading the material paper (W) is provided at the rear end of the die holding plate (13). This adsorption device
(42) is a structure in which a swing lever (48) equipped with a suction cup (47) is swung at a predetermined timing by a drive device (43), and the above-mentioned operation is performed when the mold holding plate (13) is in the initial position. As in Example 1, the front edge of the uppermost material paper among the material paper (W) (W) stacked on the stock table (41) is adsorbed, and the die holding plate (13) advances as the punching operation progresses. When moving to the final position, the material sheet (W) is moved above the lower roll (2b) in the suctioned state. Then, when the die holding plate (13) reaches the final position, the suction by the suction cup (47) is released, and as shown in FIG. 20, the material paper (W) is moved to the moving area of the die holding plate (13) and the lower roll. (2
It is supported at a predetermined position by a support base (5a) arranged between the rear area of b). And the material paper (W) at this time
The position of the front end of the mold holding plate (13) is set to a position advanced to the front of the position of the stopper (16) mounted on the mold holding plate (13) when it returns to the initial position.

Therefore, the punching operation is completed and the die holding plate is
When (13) is returned to the initial position by the horizontal drive (HD), the stopper (16) contacts the front edge of the material paper (W) immediately before the mold holding plate (13) returns to the initial position. This material paper
(W) is returned to the specified degree. Then, when the die holding plate (13) returns to the initial position, the material sheet (W) is positioned so that the front edge of the material sheet (W) and the stopper (16) are surely in contact with each other.

As described above, since the raw material sheet (W) is once moved excessively forward, it is returned to a predetermined position in a state of being in contact with the stopper (16), so that the positioning accuracy of the raw material sheet (W) is high. Is improved. In this example, the scrap (S) is the top roll
(2a) and the lower roll (2b) are equipped with a rotary cutter (77) for cutting provided in front of them, and the scrap (S) sent forward by the lower roll (2b) is punched out. At this point, it is transferred to a belt type moving device (78) provided in front of the lower roll (2b), and is thereby sent out forward, thrown into the rotary cutter (77), and cut into small pieces.

Next, the overall operation of the second embodiment having the above configuration will be described below. When the motor (9) is operated, the oscillating gear (93) is driven in the direction of the solid line arrow in FIG. 15, and at the same time the cam (92) rotates and the large diameter portion (92a) of the oscillating arm (95a) moves. ), The lower roll (2b) is lifted in contact with the input end (98), and the upper roll (2a) is linked with the link (97) so that the upper roll (2a)
Pressed against the upper surface of (13). At this time, the drive roll (2c), which is transmitted to the motor (9) by the operation of the air cylinder (E), is pressed against the surface of the lower roll (2b), and the lower roll (2b) is pressed.
(2b) is rotationally driven by friction transmission with the drive roll (2c).

Since the blade die forming surface (KC) of the flat die (K) attached to the die holding plate (13) is set to bite into the surface of the lower roll (2b), the lower roll (2b) The mold holding plate (1
3) and the flat type (K) attached to this are moved forward.
However, in this embodiment, the mold holding plate (13) is also driven forward in synchronization with the rotation of the drive roll (2c) by the horizontal drive (HD) that is transmitted to the motor (9) through the oscillating gear mechanism. To be done.

By the above, the punching operation is started,
When the lower roll (2b) is lifted, at the same time, the uppermost material paper (W) of the certain size material paper (W) (W) stacked on the stock table (41) is adsorbed by the adsorption device (42). It
Therefore, as the punching operation progresses, the die holding plate (13)
The material sheet is moved to the punching section side by the lower roll (2b) and the flat die (K) while being held by the suction device (42) attached to the rear end.

When the punching of the entire area of the punched portion of the material paper (W) is completed, the change point (92b) of the cam (92) from the large diameter portion (92a) to the small diameter portion is changed as shown in FIG. Depending on the setting, the lower roll (2a) is slightly lifted and the lower roll (2b)
Is moved down from the flat type (K). Due to the transmission relationship between the oscillating gear (93) and the horizontal drive (HD), the die holding plate (13) is located at a position slightly moved forward from the completion of the punching operation.
Since it is set to the final position of
When (13) reaches the final position, the material paper (W) held by the suction device (42) connected to this rear end is positioned slightly ahead of the material paper position at the start of punching. At this point, the suction device (42) releases the material paper (W) and maintains the material paper (W) in a predetermined posture.

Thereafter, the oscillating gear (93) is rotated in reverse, the air cylinder (E) is returned to operate, the drive roll (2c) is separated from the surface of the lower roll (2b), and the horizontal drive unit (HD) is moved. The returning operation returns the die holding plate (13) to the initial position. During this returning operation, the upper roll (2a) and the lower roll (2b) are in a state where they are open to each other, so the mold holding plate (13) and the flat mold (K) attached to it are returned with a light force. Driven.

When the die holding plate (13) is returned to the initial position, the front edge of the material paper (W) which has been set slightly forward is moved to the front of the die holding plate (13) as shown in FIG. When it is pushed back by the stopper (16) provided at the end and the mold holding plate (13) returns to the initial position, the blade mold forming surface (KC) of the flat mold (K)
And the material paper (W) match exactly. After that, the series of operations described above is executed in accordance with the rotation of the motor (9), and the material sheets (W) stacked on the stock table (41) are sequentially put into the punching section to finish the products (A) (A). Will be punched by.

Embodiment 3 In all of the above embodiments, the products (A) and (A) are punched out from the material paper (W) of a fixed size, but as shown in FIG. The product (A) and (A) may be punched out from the (W). As a punching mechanism part,
Although the above-mentioned Embodiments 1 and 2 can also be adopted, in this embodiment, the urethane rubber belt (V) is wound between the side roll (2d) and the pressure roll (20) to form the lower roll. (2b)
I am trying. This belt (V) is pressed against the blade mold forming surface (Kc) of the lower surface of the flat mold (K) by the pressure roll (20), and the products (A) and (A) are punched from the material paper (W). . Further, the belt (V) also functions as a product takeout device.

A coil for scrap is wound on the punching mechanism.

But the substrate paper (W) shrinks slightly in the longitudinal direction
If the feed roller (55) (55) is
It may be slightly slower than the punching speed. This practice
In the example, the paper feed roll (L₂) Material paper (W)
Also bend it in a wave shape and guide it to the feed rollers (55) (55).
Free roller (L_Four) Is provided.

Further, the upper roll (2a) and the mold holding plate (13) are transmitted to a chain drive device driven by a servomotor (56), and the peripheral degree of the upper roll (2a) and the mold holding plate (13). It is set to match the horizontal reciprocating speed of. The drive speed of this servo motor (56) is the same as that of the feed rollers (55) (55).
The material paper feed speed according to is matched. In this example, the flat mold attached to the mold holding plate (13) in the initial position
The pressure roll (20) is lifted with respect to (K), and the belt is wound around the pressure roll (20) as it rotates.
(A) and (A) are punched out from the material paper (W) sandwiched between (V) and flat mold (K), and pressure is applied when the mold holding plate (13) moves to the final position. The roll (20) descends from the flat type (K). During this period, the winding roll (L ₁ ) executes the winding operation to wind the scrap (S) and
(K) and the belt (V) wrapped around the pressure roll (20)
It is moved almost in rolling contact. At this time, the material paper (W) is pulled out from the paper feed roll (L ₂ ) by the feed rollers (55) and (55) in synchronism with or almost in synchronism with the moving speed of the flat mold (K). When (20) moves down from the flat type (K), the operation of the feed rollers (55) (55) is stopped. At this time, the winding operation of the winding roll (L ₁ ) is continued, but since the free roller (L ₃ ) is provided, it is lifted and the movement of the material sheet at the punching section is stopped.

Thereafter, the mold holding plate (13) fitted with the flat mold (K)
When is returned to the initial position by the chain transmission device, the pressure roll (20) rises again to contact the blade forming surface (Kc) of the flat mold (K) and the material paper (W) to the belt ( The pressure is clamped between V and V, and the punching operation is restarted as the pressure roll (20) rotates, and at the same time, the winding operation by the winding roll (L ₁ ) is also started. In this way, the punching operation is performed intermittently, the continuous strip-shaped material paper (W) is pulled out by the required amount, and the continuous strip-shaped scrap (S) is wound up at each punching operation.

In the illustrated embodiment, the punching portion is pulled.
The scrap (S) discharged is continuously wound up.
Paper feed roll (L₂) Is equipped with a brake device and punched
Paper feed roll (L₂) From
And take-up roll (L ₁) Is synchronized with the punching operation.
Alternatively, the structure may be such that intermittent rotation drive is performed. Example

Is also good. In the case of this Example 3, the belt (V) is
Since it functions as a chute for the product, the product discharge operation is reliable.
It ’s true.

Next, another method for forcibly separating the product (A) (A) and the scrap (S) will be described below. In the first embodiment, the rear end of the scrap guide (71) is set to the lower roll (2b).
The product (A) and (A) outlets are provided near the product (A) and (A) exits to provide a separating action between the product (A) and (A) and the scrap (S) during punching. There are the following methods to do this.

Separation plate (S
This is a method of arranging E) in parallel. This separation plate (SE) is flat type (K)
A vertical plate having an upper end inserted between the row of blade dies (11) (11) and the row of blade dies (11) (11) in the moving direction is a wedge-shaped rear part. In this method, the product from the lower roll (2b)
When (A) (A) and scrap (S) come out, scrap (S)
The tip of is pushed up by the separation plate (SE),
Further, the scrap (S) slides on the separation plate (SE), moves forward, and is discharged. In addition, the product (A) (A) is a blade type (1
1) Since it is pushed down by the sponge layer (12a) in (11), it is completely separated from the scrap (S), and is separated from the adjacent separation plates (SE) (SE) onto the shunt (61). You will have to escape.

The separation plate (SE) is scrap (S).
And not only to separate the products (A) (A) from each other, but also to separate the columns of the products (A) (A) from each other. Therefore, the products (A) (A) discharged from the punched portion are easily accumulated. Further, in the first and second embodiments, the scrap (S) is discharged forward from above the product (A) (A) take-out portion, but the products (A) (A) are discharged one after another. If you take this scrap
The (S) stacking part interferes with the work. In order to prevent this inconvenience, the configuration shown in FIGS. 25 to 27 can be adopted. In this case, as shown in FIG. 27, in the flat mold (K), no sponge layer is provided between the blade molds (11) (11) rows of the flat mold (K). Further, as shown in FIG. 25, in the product discharging portion, a group of separation plates (SE) (SE) provided in conformity with the above-mentioned blade molds (11) (11) were set upright from the shoot (61). It is configured. The tip of each separation plate (SE) is wedge-shaped, and the lower end edge thereof is shaped so as to follow the lower roll (2b), and between them, it is appropriate to allow the scrap (S) to pass. Spaced.

According to this construction, the blade dies (11) (11) are placed at positions where the products (A) and (A) are sequentially punched out and passed through the lower roll (2b).
The product (A) (A) therein is extruded downward by the sponge layer (12a) and escapes onto the shoot (61). In addition, the product (A)
(A) will be moved to the front position and accumulated by the shoot (61). On the other hand, as shown in FIG. 26, the scrap (S) is positioned between the blade dies (11) and (11), and further separated from the blade dies (11) and (11) by the separation plate (SE),
From the gap between the lower roll (2b) and the lower edge of the separation plate (SE) (SE), it is guided to the scrap (S) accumulation section below the shunt (61). As a result, the accumulation of products (A) and (A)
(S) is carried out in front of and solves the above workability problem.
