BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended to ensure that punching debris is reliably discharged from a local portion such as an independent hole portion or a thin cut portion which is mainly generated in a punching step of forming a blank such as a box from a flexible sheet in a manufacturing process of a paper container. The present invention relates to a device for removing local punching scraps that can be removed.

2. Description of the Related Art Conventionally, in the process of manufacturing a paper container, a blank is once cut into a desired shape from a raw material sheet in a die-cutting process in which a blank such as a box having a desired shape is punched from a flexible sheet material (raw material sheet). The process for removing the punching chips is performed by moving to the next processing step (the step for removing the punching chips) without separation.

In this process for removing punching chips, as a means for efficiently removing the punching chips generated at the peripheral portion of the blank, the intermediate independent hole portion, or a narrow cut portion, it is mounted on the upper die and pushed. When sandwiching and dropping the punching scraps that are pulled out by the push-up piece due to the rise of the lower mold, by the piece and the scrap receiving piece that is vertically movable facing the punching hole provided in the lower mold, The inventor's tip is to use a local punching scrap removing device that is displaced so as to be displaced with respect to the thrusting piece as the punching scrap receiving piece on the lower side moves downward, and operates so as to knock off the punching scrap. It is known as an invention from Japanese Patent Publication No. 6-94117 or Japanese Patent Publication No. 8-11394.

[Patent Document 1] Japanese Patent Publication No. 6-941
The prior art known from Japanese Patent Publication No. 17 or Japanese Patent Publication No. 8-11394 is used as a means for removing small punching scraps to some extent, but is used in the manufacturing process of paper containers. As the working speed of the punching device is gradually increased, there is a problem that the local punching scrap removing device cannot smoothly remove the punching scrap.

As a phenomenon in which the removal processing of the scrap by the local punch scrap removing device is not smooth, a portion where the punch scrap is sandwiched between the pushing piece from the upper die side and the scrap receiving piece on the lower die side and punched However, when the lower die is lowered, the punch scraps that are attached to the lower mold and restored when the scrap scrap pieces are restored are often not punched out, and are often sandwiched and lifted again. . This is partly due to the so-called timing shift, in which the scraps that are once punched adhere to the punch scrap receiving piece immediately before they drop due to the high operating speed in the punch scrap processing process. Is considered to be. If such a punching scrap removal operation is not performed reliably, it may cause an obstacle such as biting of scraps left unmoved in the moving part while moving the blank to the next step, and it may damage the product. Therefore, there is a problem that defective products are generated.

For this reason, the present inventor has conducted various researches on the means for removing punching scraps and has already made many proposals for various types of removal means. An elastic body such as a spring is used in order to increase the restoring speed of the punching scrap receiving piece and to return the punching scrap receiving piece after returning to the next operation quickly. By adding such functions to improve workability,
Corresponding to the processing speed of punched chips is also considered to be a cause of the above-mentioned problems. In any case, removing local punching dust such as small independent holes or narrow cuts formed in blanks such as boxes seems to be a simple and quite troublesome problem, and it is often a solution to that problem. There are drawbacks.

The present invention has been made in order to solve such a problem, and ensures the operation of extracting the local punching dust by the cooperation with the thrusting piece in the process of removing the punching dust. Moreover, it is an object of the present invention to provide a local punching scrap removing device having a return function capable of coping with high speed operation with a simple structure.

[0008]

In order to achieve the above-mentioned object, a device for removing local punching scraps according to the present invention is a device for removing local punching scraps used in a blanking process of a blank such as a paper container from a sheet material. In the removing device, the punching dust receiving support mechanism, which is attached to the punching dust removing upper die to face the punching dust removing upper die, is such that the tip receiving portion faces the pushing pushing piece end. A scrap receiving piece that is arranged and supported rotatably downward in a required range, and a support frame that has a space for pivotally supporting and storing the base of the scrap receiving piece and that can be mounted on the lower mold. from it, the punching waste receiving member being adapted tip receiving portion begins to come collision from the support frame, front lower portion of the support frame by increasing the lower half of the base and its vent waste receiving piece lower half front Due to the magnetic force between Is the vent waste receiving member so as to keep in position after punching chip removing operation, receiving the punching waste
The tip receiving portion of the piece is formed of the lower half portion and the support frame.
The elastic structure is slightly weaker than the adsorption and holding force due to the magnetic force between
It is removed by the cooperation of the pushing piece attached to the upper die.
It is configured to bend downward at the beginning of the chip holding operation.
And it is characterized in that they are.

According to the local punching dust removing apparatus of the present invention thus constructed, when the dust removing operation is started after the punching dust removing process is started, the punching dust removing lower die is lifted to move downward. The tip receiving part of the scrap receiving piece of the punch scrap supporting mechanism attached to the die is attached to the upper die in a state where it is in contact with the lower side of the corresponding part that becomes the punch, and the part that becomes the scrap at the end of the pushing piece Press. Then, a part of the portion to be the scrap is sandwiched by the end of the pushing piece and the tip receiving portion of the scrap receiving piece. Further, as the lower die rises, the tip receiving portion of the scrap receiving piece that receives a part of the scrap to be held on the lower side against the stationary pushing piece is pushed up to become scrap. The part is pushed down by one end and pushed down to separate the connecting part. At this time, the scrap receiving piece is separated by the downward turning force of the tip receiving part from the state where it is attracted and held by the magnetic force between the front surface of the lower half part and the front lower part of the support frame, and is rapidly attracted by the magnetic force. Since the force is lost, the action force for supporting the scrap from the lower end receiving portion from the lower side disappears after passing a certain rotation angle range. As a result, the separated scraps fall, and since the bottom half of the scrap receiving piece is lengthened and the center of gravity is at the bottom, it is quickly reversed and returned.
When it returns to the action range of the magnetic force, it is adsorbed by the magnetic force and returns to the fixed position, so that the next operation can be performed.

According to the present invention that operates in this manner, the switching away Suma the joining portion sandwiching the portion to be a vent debris between the pushing piece of the upper mold side to the operation made reliable, venting after disconnecting When the scrap receiving piece returns, the restoring force of its own weight is used to prevent the positive addition of restoring force from being given in the initial stage of returning, so the separated scraps will not be lifted again and will be separated and dropped. And surely removed,
This has the effect of preventing the occurrence of defective products. Moreover, since it functions with an extremely simple structure, it has an effect that it can be provided at a low cost without any failure.

In addition, the bending of the tip receiving portion of the scrap receiving piece
Therefore, the scrap receiving piece held by the magnetic force
Time to overcome the holding force of the
Make sure to perform the operation to reliably separate the connecting part of the scraps by the difference.
Along with this, the contact pressure with the pushing piece against the scrap piece is reduced.
To move the next operation displacement of the scrap receiving piece.
By the movement of the tip receiving portion and the pushing piece
It makes it easy to separate and drop pieces, and has a pinching function for scrap pieces.
The effect is that it can be resolved more reliably.
To have such a function, make the tip receiving part elastic.
For structures (in some cases, structures that incorporate leaf springs, etc.)
It is preferable to configure.

The scrap receiving piece is rotatably supported with its base pivot point set in the vicinity of the upper corner of the space forming portion of the support frame, and the tip receiving part is supported in a steady state before operation. out-out required length butt forwardly from the end, in a posture facing the jogger one end of the upper mold side receiving surface, are formed long or less base, the lower front or front lower portion of the support frame of the lower half portion It is preferable that the magnet is attached and held by one of the magnets. By doing so, the radius of rotation of the tip receiving portion can be reduced, and conversely, by increasing the magnetic force applied to the lower half portion having a large radius of rotation between the front lower portion of the support frame and the rotation radius ratio, the tip receiving portion Collaborates with the pushing piece to secure the pinching force of the part that becomes the scrap until the operation of separating the connecting part of the scrap is reliably performed, and after separating the connecting part, it quickly becomes When the lower die is retracted (lowered), the lower half of the lower mold part rotates the scrap receiving piece in the restoring direction,
The reason why it is possible to perform a natural operation that the suction force by the magnetic force is exerted between the support frame side and the lower half part of the scrap receiving piece to quickly restore and hold the scrap receiving piece,
The effect is that the scraps can be reliably removed without any trouble.

The scrap receiving piece has a structure in which its lower end is separated from the pivotal support portion of the base to give an elastic force so that its tip receiving portion can be bent downward, and the whole is molded of synthetic resin. It is good that it is characterized by being. By doing so, the scrap receiving piece can be integrally molded with a synthetic resin having high mechanical strength, and elastic force can be imparted to the tip receiving portion so that the tip receiving portion can bend, and the manufacturing cost can be reduced and an effective product can be obtained. You can

The receiving surface of the tip receiving portion of the scrap receiving piece has an appropriate section from the tip to a position near the base,
It is preferable that the tip end is inclined downward to the pivot axis side, leaving a small portion. With this configuration, when the connecting portion of the portion that becomes the scrap due to the cooperation with the pushing piece is torn off, even if the protruding amount of the tip receiving portion is short, the sandwiching surface can be widened and effectively separated. There is an effect.

Further, according to the present invention, the latter half portion is formed lower than the thickness of the punching scrap removal lower die by an equal amount with respect to the front half portion which includes a space portion for rotatably receiving the cutting scrap receiving piece of the support frame. It is preferable that the mounting bolt positions are arranged in the vertical direction at a position separated from the rear end surface of the front half portion of the support frame by a predetermined dimension. By doing this, the front half of the support frame fits a part of the punching scrap removal lower die so that only the tip receiving portion of the scrap receiving piece projects from the end of the support frame in correspondence with the scrap removal position. In addition to the notch, the dimension from the inner end of the notch to the insertion hole position of the mounting bolt is determined. Therefore, if the bolt hole is opened at that position, the positioning can be performed easily and reliably. Moreover, since a part of the support frame is fitted into the lower substrate and fastened and fixed by the mounting bolts, even if an external force due to repeated scrap removal operations is applied, the fastening portion does not loosen and is in a stable state. It has the advantage that it can be used with.

And a punching dust receiving mechanism 10 attached to a position adjacent to the punching dust dropping hole 4 (cut-off edge) in the lower die 3. The pushing piece 5 and the scrap receiving portion (corresponding to a tip receiving portion 17 described later) of the punch scrap supporting mechanism 10 are positioned so as to correspond to each other, and the scrap receiving portion is the scrap dropping hole 4 Arranged to face inside.

The punching dust receiving and supporting mechanism 10 is provided with a support frame 11 attached to the lower die 3 for removing punching dust and a tip receiving portion 17 which is incorporated in the support frame 11 and protrudes from the front end portion thereof. And a scrap receiving piece 16 that is movably pivotally supported.

As shown in FIG. 2, the support frame 11 is provided with a space portion 12 in the front half portion 11a by opening a part of the upper surface and the front surface, and the rear half portion 11b is attached to the upper portion for removing scraps. Lowered by the thickness of the lower mold 3 of the mold, a bolt hole 13 is formed in the vertical direction at a position separated from the rear end surface 11a 'of the front half 11a by a predetermined distance. Then, a pivot shaft supporting portion (a pivot shaft hole 14 ') of the scrap receiving piece 16 is provided in the front upper corner portion 11c, and the steel plate piece 15 is vertically embedded in the front lower portion 11d from the lower end to an appropriate height position. The whole is molded from plastic. If necessary, metal plates may be arranged on both side surfaces (front and back with respect to the paper surface of the drawing), and the middle part may be laminated with non-ferrous metal or resin.

The scrap receiving piece 16 has a base portion 16a supported by a pivot shaft 14 which is inserted into a pivot shaft hole 14 'provided in a front upper corner portion 11c of the support frame 11, and the support frame 11 thereof. Is disposed in the space 12 of
The front end receiving portion 17 projects forward from the support frame 11 and is formed downward from the base portion 16a by a required length to provide a magnet 18 at a position in front of the lower half portion 16b.
Is embedded so that the center of gravity is located below, and is formed of a plastic having high mechanical strength and elasticity (for example, nylon). The magnet 1
It is preferable that the surface of the steel plate piece 15 embedded in the side of the support frame 11 that is in contact with the end surface of 8 is located on the vertical plane passing through the axis of the pivot shaft 14.

Further, the tip receiving portion 17 of the scrap receiving piece 16
As shown in FIG. 2, an appropriate space portion 17b is provided from the support portion of the pivot shaft 14 toward the tip thereof, and the upper portion thereof is made as a flexible elastic piece 17a. The upper receiving surface 17c of the emitting portion piece 17a is formed so as to have an appropriate dimensional interval downward from a position slightly closer to the base portion 16a side from the tip. It should be noted that the space portion 17b formed below the resilient portion piece 17a is equivalent to maintaining the attraction force by the magnet 18 provided in the lower half portion until the resilient portion piece 17a is completely bent. It is desirable to set the dimensions so that the amount of bending to be obtained is obtained. Further, the inclination of the receiving surface 17c formed on the upper side of the resilient part piece 17a is such that when the scrap receiving piece 16 is rotated to a position where the connection of the scraps is cut and separated. It is preferable that the five ends and the receiving surface 17c are set so that the sandwiched positions of the scraps are substantially parallel to each other.

The lower half portion 16b of the scrap debris receiving piece 16 configured as described above is momentarily rotated by its reaction when the punch scraps are removed by cooperating operation with the pushing piece 5. A stopper 11 provided on the upper surface of the support frame 11 side so as not to rotate upward from the upper end surface of the support frame 11.
A notch 16d is provided at the rear end of the lower half portion so as to be engaged with and locked with e.

As shown in FIG. 3, the local punching dust removing device 1 of the present embodiment having the above-described structure has the punching dust receiving mechanism 10 in the punching dust removing lower die 3 in the punching dust processing step. The front half 11a of the support frame 11 is fitted into the notch 3a provided adjacent to the scrap removal hole 4 (or the edge removal portion), and the position is aligned. It is attached by penetrating it through the countersunk bolt 20 and tightening the tip receiving portion 17 so as to face the push-pushing piece 5 attached to the punching dust removing upper die 2. At this time, as described above, the support frame 1
Since the front half portion 11a of No. 1 is fitted into the notch and tightened by bolts, the mounting posture is stable, and there is no displacement due to vibration during use.

During the operation for removing punching chips, the sheet A to be processed punched in the previous step is sent to a predetermined position on the upper surface of the punching chip removing lower die 3, and the punching chip removing lower die 3 rises. The target punching portion a of the sheet A to be processed comes into contact with and is pushed down against the thrusting piece 5 attached to the upper mold 2. At this time, when the lower die 3 for removing punching chips is lifted, first, the sheet pressing piece 6 made of sponge attached to the upper die 2 comes into contact with the sheet A to be processed and the punching portion a.
Stabilize by pressing in the vicinity of.

As shown in FIGS. 5 (a), 5 (b) and FIG. 6 showing the operating mode of the punching dust removing device, the punching portion a to be pushed down has the lower side thereof at the punching dust receiving mechanism 10. It is received by the front end receiving portion 17 of the receiving piece 16, and the front end receiving portion 17 of the pushing piece 5 and the scrap receiving piece 16 is received.
The punching portion a is sandwiched by and displaced to be removed.

First, as shown in FIG. 5 (a), the punching portion a sandwiched between the pushing piece 5 and the tip receiving portion 17 of the scrap receiving piece 16 has the punch receiving piece 16 at this point.
However, the magnet 18 embedded in the lower half portion 11b thereof and the steel plate piece 15 attached to the lower front portion of the support frame 11 do not easily move due to magnetic attraction, and the end of the pushing piece 5 and the tip receiving portion 17 are not moved. The punched-out portion a is strongly sandwiched by the receiving surface 17c of. Then, as the lower mold 3 rises, the tip receiving portion 17
The elastic piece 17a on the side bends downward due to the pressing force.

Due to the pressing force of the thrusting piece 5, the elastic piece 17a of the tip receiving portion 17 of the scrap receiving piece 16 bends to the maximum extent in the space portion 17b formed below the pivot shaft 14 portion. Then, as shown by the symbol i in FIG. 5B, the punching portion a is torn off at the connecting portion with the blank side. In this state, the punched portion a is still sandwiched by the receiving surface 17c of the tip receiving portion 17 and the end of the pushing piece 5.

Further, when the lower die 3 continues to move upward, the push-pushing piece 5 interposes the punched portion a and the lower scrap receiving piece 1
6, the tip receiving portion 17 (including the elastic piece 17a) is pushed down by overcoming the attraction force by the magnetic force between the magnet 18 and the steel plate piece 15. Then, as shown by the chain double-dashed line e in FIG. 6, as the descent progresses, the scrap receiving piece 16 rotates clockwise around the pivot shaft 14 as a fulcrum, and the lower half portion 1
The magnet 18 attached to 6b is separated from the steel plate piece 15 attached to the support frame 11. In this case, the attraction force due to the magnetic force is rapidly lost, so that the scrap receiving piece 16 is in a free state, and is largely rotated by the addition of the pushing down force by the thrusting piece 5 (shown by the solid line).

Then, the punching portion a which has been sandwiched between the end of the pushing piece 5 and the receiving surface 17c of the tip receiving portion 17 until then.
When the scrap receiving piece 16 becomes free, the elastic restoring force of the resilient part 17a and the rotational displacement of the receiving surface 17c of the tip receiving part 17 are caused during the movement as described above. The tip receiving portion 17 of the scrap receiving piece 16 is retracted with respect to the thrusting piece 5 which is released in a state where the gripping force is released and recedes. Will be eliminated.

In this way, the punching portion a (scraps) is removed, and when the lower die 3 is moved up to the descending stroke, the scrap receiving piece 16 is not restrained at all and acts on the lower half portion 16b thereof. It automatically rotates back by its own weight. Immediately before the return, the magnet 18 and the steel plate piece 1
It is quickly returned to the fixed position by the suction force of 5 and kept stationary.

In the scrap receiving piece 16 of the present embodiment, the punching portion a of the sheet A to be processed is sandwiched between the pushing and pushing piece 5, and the connecting portion is formed by the initial bending effect of the elastic portion piece 17a provided on the upper portion. It is proposed in the related art that the tip receiving portion 17 that is operated to drop downwardly is configured to be pivotally operated by the pivot 14 at the upper corner of the support frame 11 The displacement distance (turning radius) on the receiving side can be made smaller than that of this type of punching scrap removing device, and as a result, it is possible to quickly remove the cutting scraps without adopting a complicated mechanism. Became. When the lower die 3 (cutting piece receiving piece 16) shifts to the backward stroke, the cutting pieces have already been removed, and thus the punched pieces (punching part a) once pushed down.
The effect is that the scrap can be completely removed without being lifted again and remaining.

Further, the punching dust removing device of this embodiment is
Since the front half 11a of the support frame 11 can be positioned by fitting it into the notch 3a formed in the lower mold 3, the position of the bolt hole for mounting provided in the latter half 11b is determined, so that the lower mold 3 Can be installed as set. Further, even after mounting, there is no displacement, and correct operation can always be performed.

In the above description of the embodiment, the elastic piece 17a provided on the upper end of the tip receiving portion 17 of the scrap receiving piece 16 is made of a plastic material integrally molded with other portions. The thing is described. The elastic piece may be formed by incorporating a leaf spring into the scrap receiving piece, if necessary. With this, durability can be further enhanced.

Next, FIG. 7 shows a front view of another embodiment. Device 1 for removing local punching waste of this embodiment
A has almost the same basic configuration as that of the above-described embodiment, and therefore, the same or similar portions are denoted by the same reference numerals as those of the above-described embodiment and detailed description thereof is omitted.

This local punching dust removing device 1A is provided with the same punching dust receiving mechanism 10A as described above, and the structure of the tip receiving portion 17A of the punching dust receiving piece 16A is partially different from that of the above embodiment. . The other structure is almost the same as that of the above embodiment. Therefore, only the different configuration will be described.

Tip receiving portion 1 in the scrap receiving piece 16A
7A is formed integrally with the receiving surface 17c, which is formed on the upper surface, and is formed with a slope down from a position slightly closer to the base 16a side from the tip of the receiving surface 17c, with an appropriately sized section. It should be noted that, when the scrap receiving piece 16A is rotated to a position where the connection of the cut scraps is cut off, the slope of the scrap is substantially parallel by the end of the pushing piece 5 and the receiving surface 17c. It is better to set the status. In this way, the state where the attraction force by the magnet 18 is approaching the limit at which the magnet 18 weakens is reached at that point.

Also in this embodiment, when removing punching dust, the same operation as in the above-mentioned embodiment is carried out, but since there is no resilient part piece, the push-pushing piece 5 (see FIG. 3) and the dust receiving piece are received. Receiving surface 1 at tip receiving portion 17A of piece 16A
When the punching portion a (described with the same reference numeral as in the above-mentioned embodiment) is sandwiched by 7c and the cutting operation is performed, the relative position displacement of the upper and lower dies in the sandwiched state of the punching portion a by the both. As a result, when the pushing force of the thrusting piece 5 is increased and the balance with the suction holding force by the magnetic force acting on the scrap receiving piece 16A is lost, the scrap receiving piece 16A rapidly rotates around the pivot shaft 14. The punching piece a moves, and the pushing-down force exerted on the punching portion a is large, the connecting portion of the punching portion a is cut off, and at that moment, the clamping force is lost and the punching portion a is repelled and dropped. It will be. As a result, the punching portion a is not attached and returned during the restoring operation of the scrap receiving piece 16A.

According to this embodiment, the punching portion is clamped from the upper and lower sides and after a certain timing, the pushing-down piece is caused to perform the pressing action at once.
The use of the punching dust receiving mechanism 10A of this embodiment is effective when the punching portion a which is the punching dust is relatively large.
