DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punched-out separation type drop-off portion support which is mainly used in a process of manufacturing a blank such as a paper box by punching a material sheet such as cardboard or paperboard.

[0002]

2. Description of the Related Art When manufacturing a paper container or the like by punching a material sheet such as a cardboard or a paperboard, the material sheet is die-cut into a required shape by a punching die, and the material sheet die-cut in the next process. A portion that becomes so-called scrap other than a portion that becomes a product from the waste is removed by a punching waste separating device.

Conventionally, in such a punching apparatus, for example, as shown in FIG. 4, a material sheet 10 in which a punching line 101 is formed by performing die punching in a punching step.
In order to separate the parts which are to be punched chips other than the product part 102 from 0, the normal product part 102 and the part which is to be chipped 1
Numeral 03 indicates that a plurality of narrow connecting portions 104 are provided at appropriate intervals at a plurality of locations in order to shift from the punching step to the next punching waste separation step, and can be moved to the punching waste separation step. Therefore, as a punching waste separation type used in a punching waste separation device, for example, as shown in a perspective view of FIG.
A lower die 110 having a shape slightly smaller than the outer shape of the product forming portion, and a punch other than the product, so that a product portion 102 and a portion 103 serving as a scrap can be separated from the material sheet 100 on which the punching line 101 is formed. In order to separate the waste portion from the product forming section, the upper mold 111 is provided with a pair of the upper mold 111 having a scrap pushing-down member 113 having an inner peripheral edge slightly larger in size and size than the product forming section for receiving the lower mold 110. Things are used.

[0004] A punching line (1) is formed on the upper die 111 of the scrap separation type by cooperation with the lower die 110.
01) is formed from the material sheet 100 to the product portion 10
In order to separate 2 from each other, a scrap removal member 113 having a required height from the substrate 112 is provided at a required location. Reference numeral 114 in the drawing denotes a sponge separating elastic member provided at an appropriate position within a range surrounded by the scrap push-down member 113. Reference numeral 115 denotes a lower mold substrate, and 116 denotes a crossbar for attaching the lower mold to the apparatus. Reference numeral 117 denotes an open hole for releasing air resistance generated between the upper and lower molds which are closed during the scrap separation operation.

[0005]

In such a punched-die separation type, a metal strip-shaped member is generally bent as a punched-out member 113 so as to be bent in accordance with the shape of a punched product portion and implanted in a substrate. In this case, the processing work by the skilled person is required, which not only requires a lot of trouble, but also requires the provision of the swarf dropping member 113 and the processing.

In view of the above, recently, when a lower mold is manufactured, the lower mold is cut out using a laser beam in accordance with the shape of a punched product portion. In this regard, there has been proposed a punched chip separation type which has been focused on using the chip as a dropping member and has been able to be rationalized. As shown in the front view showing the upper die of the punched-die separation type in FIG. By using the remaining part after the lower die is formed, the upper die 10 and the lower die 11 (FIG. 3 (b) show the lower die) for extracting the product part from the punched material sheet along the punching line. (A plan view is shown). In order to do this, the required size punch-out member 13 is formed from the surface of the substrate 12 of the upper die 10 (a plurality of pieces are formed in accordance with the shape. It is necessary to mount it while floating. For this purpose, the scrap removal member 13 is attached to the surface of the substrate 2 with a countersunk bolt (not shown) via a spacer 14. Of course, for the scraping member (not shown) at locations other than those where the outer periphery of the product part is removed, a plate material (plywood) is formed with an outer shape that matches the shape, and attached to the board surface with spacers interposed. Have been. In the figure, reference numeral 17 is an elastic body,
18 is a watermark hole.

In such a punching waste separation type, for example, when separating and removing a cut-out portion along the outer peripheral portion of a product portion from a material sheet on which a punching line is formed, the outer peripheral portion is separated as it is. It is large in size, and it becomes a large scrap with a bent portion in the state surrounding the product part, so it is inconvenient for subsequent handling, and when it is dropped, the scrap is further divided and separated. I have. Therefore, in the punching waste separation type, the lower die 11
The cutting blades 16 and 16 'are attached to required places, and the cutting blades 13 of the upper die 10 are attached to the cutting member 13 at positions corresponding to the cutting blades 16 and 16'. Slits 15 and 15 'are provided for receiving the chips 16 and 16', and the chips are cut by the cutting blade 16 (16 ') and the slit 15 (15') during the chip separation operation.

[0008] However, if the operation of separating and removing the chips is repeatedly performed, the chips fall off at the place where the cutting operation is performed by the cutting blade 16 (16 ') and the slit 15 (15'). The edge portion of the slit forming portion of the cutting member 13 is damaged, and at the time of the cutting operation, the chip is broken at the same time as the cutting of the chip, so that a large amount of paper dust is generated, and the working environment is deteriorated. Therefore, there is a problem that not only the working environment is deteriorated, but also paper dust and the like adhere to the product portion and move. In addition, there is a problem that the member 13 for dropping scraps is severely damaged in a portion easily affected by the impact force, such as a corner portion.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, the present invention effectively enhances the processing of chips at locations where problems are likely to occur, and attaches a chip-dropping member to a substrate. It is an object of the present invention to provide a punched-dust separation type push-down member support that has a function of supporting the punched-dust separation type and can enhance durability as a punched-dust separation type.

[0010]

Means for Solving the Problems and Action / Effect In order to achieve the above-mentioned object, a punching member separation type punching member support according to the present invention comprises a punching member having a required shape and a cutting surface. A punching-die separation type push-down member supporting tool which is supported and held at a required height from a support member, wherein the supporting tool is provided at a location where a local load is applied during a cutting-off operation. An engaging projection that engages with and positions the dust dropping member on the receiving surface of the main body opposite to the mounting side with respect to the substrate, and an end portion that stands upright along the side end of the received chip dropping member. And an upper end portion of the end holding piece protruding from the upper surface of the chip drop-off member in an appropriate size while supporting the chip drop-off member.

[0011] According to the present invention, the punching chip separation type plywood chip cutting member is supported on the substrate surface at a predetermined height, and a local load is increased during the chip separation operation. It is used by placing it at the receiving point, for example, at the slit forming part or corner part facing the cutting blade, so that it can be applied to the locally received load due to the cutting of the material sheet by the lower cutting edge and the periphery of the template. On the other hand, in this position, the upper end portion of the end holding piece is configured to contact before the material sheet comes into contact with the upper surface of the scrap pushing-down member. By receiving the pressing force of the cutting edge or the peripheral edge of the template, the connecting portion along the punching line and the cutting portion of the scrap can be reliably separated. At the same time, the edge of the scrap pushing-down member is protected by the end holding piece. Therefore, it is possible to improve the durability by preventing damage to the scrap falling-off member and to improve the productivity by eliminating the generation of paper dust and the like due to the damage.

The end holding piece is formed of a metal plate and is supported by a receiving surface of a scrap pushing-down member of the support body, and is parallel to an axis of an engaging projection standing upright on the receiving surface. It is preferable to be formed upright with a dimension longer than the thickness of the swarf pushing-down member which is received at a required distance from the swarf. With this arrangement, if the positioning member is positioned on the substrate so that the engaging protrusion of the support body is engaged with the engaging hole at a predetermined required support position of the chip dropping member, the chip dropping member is provided. At the same time, the upright portion of the end holding piece is arranged along the end face of the chip-dropping member, and the chip-dropping member is removed from the external force by the sheet to be processed during the chip separation operation. Edges can be protected. Then, the upright end of the end holding piece made of a metal plate is protruded from the surface of the swarf scraping member, so that when the swarf is divided, the load is concentrated on the tip and the sheet is displaced. Can be prevented, and the scraps can be cut off smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a specific embodiment of a punching member separation type push-down member support according to the present invention will be described with reference to the drawings.

FIG. 1 is an overall perspective view of the push-down member support of the present embodiment, and FIG. 2 is a partial perspective view of a punched-out debris separation type having a push-down member supported by the support of the present embodiment. Are respectively shown.

The drop-down member support 1 of the present embodiment is provided with a cubic support body 2 having a required external dimension and a central portion of the upper surface and the lower surface of the support body 2 projecting coaxially. The support projections 2 are composed of columnar engaging projections 3 and 4 having a required length, and end holding pieces 6 which are bent and formed on one side of the upper surface 5 of the support body 2.

The support body 2 is integrally formed with, for example, plastic together with the engagement projections 3 and 4 and has a top surface 5 and a bottom surface 5 'that are parallel to each other and are supported by a drop-off member (a scrap drop-off device of the present invention). The height dimension h is set so that the member (equivalent to a member) can be supported at a predetermined height on the upper mold surface. Also,
The heights h 'and h "of the engaging projections 3 and 4 are slightly shorter than the thickness of the board and the plywood forming the scrap removal member. One side edge of the lower surface 5' is provided. The portion is provided with a rotation preventing projection 8 facing downward.

The end holding piece 6 is formed by bending a thin plate of, for example, a stainless steel plate into an L-shape, and is a member for dropping out scraps placed on and supported by the upper surface 5 of the support body 2. The upright portion 6 is slightly higher than the thickness t of the thirteen.
a is formed, and a hole 6 through which the engaging protrusion 4 is inserted is provided in a portion 6b supported by the upper surface 5 of the support body 2, and the engaging protrusion 4 is inserted into the hole 7 when the hole 7 is inserted. The distance s from the center of the hole 7 to the inner surface of the upright portion 6a is in contact with the end face of the supporting push-down member 13.

The push-down member support 1 of the present embodiment formed in this manner is a punch-out push-down member 1 provided on an upper die 10 of a punching-die separation type as shown in FIG.
3 serves as a spacer to be attached to the surface of the substrate 12 at a required height, and is particularly used as a part of the push-down member 13 where the cut-off blade receiving slits 15 and 15 'are formed and a support part at a corner or the like. Can be

To mount the push-down member support 1 on the substrate 12, first, a mounting hole is formed in the substrate 12 at a position designed in advance, and the push-down member support 1 is inserted into the mounting hole. The support projection 2 is fitted with the engagement projection 3 protruding therefrom. At this time, it is preferable that the fitting between the mounting hole and the engagement protrusion 3 is such that the fitting can be firmly fitted. Further, when the support body 2 is mounted on the substrate 12, the orientation can be determined by providing a small hole for engaging the rotation preventing projection 8 on the lower surface and fitting the small hole. Thus, the substrate 1
After the supporting body 2 is mounted on the surface of the supporting body 2 in a required distribution, the end holding pieces 6 are placed on the upper surface 5 of the supporting body 2, and the receiving projections 4 are inserted into the holes 7 with the supported portions 6 b in the holes 7. A position where the upright portion 6a is fitted and severely subjected to the cutting operation of the punching waste;
For example, it is placed on the slit 15 (15 ') forming portion (see FIG. 2).

After that, the push-down member 13 is received by the support so that the upward engaging projection 4 of each support 1 fits into the hole for positioning engagement formed in advance. Then, it is fixed to the substrate 12 at a separate position by bolts 18 with flat heads. In addition, even if it is other than a corner part and a slit formation part mentioned above, it can be attached so that the upright part 6a of the end holding piece 6 may be along the cutting operation edge at the part along the punching line.

The push-down member 13 mounted on the substrate 12 in this manner is a place where the conditions acting on the push-down member 13 are not good in the operation of separating the punched waste by the upper die 10 and the lower die 11. In each case, the end face portion is an end holding piece 6
When the tip of the upright portion 6a of the end holding piece 6 that is surrounded by the upright portion 6a and projects from the surface of the push-down member 13 contacts the material sheet provided with the punching line, (The cutting blade 16 is the slit 1
When the material sheet is cut in the positional relationship with the material sheet 5), first, the tip of the upright portion 6a of the end holding piece 6 comes into contact and acts so as to bite into the material sheet. Therefore, the drop-off member 1
When the three surfaces or the cutting blade 16 is cut, the material sheet is surely cut without causing a shift. In addition, the end holding piece 6 is damaged by the side surface of the upright portion 6a without the function of separating the contact resistance due to the scraps acting on the heavily loaded end portion of the push-down member 13 without directly applying the load to the end of the push-down member 13. Can be prevented.

As described above, according to the punching member drop-off member support 1 of the present embodiment, the problem of the conventional punching chip separation type is solved, and the plywood drop-out member is interposed on the substrate by the spacer. In the case of the type adapted to be mounted, an excellent effect can be exhibited to solve the problem, and a better effect can be obtained.

In the above-described embodiment, a description has been given of a case where the end holding pieces 6 separately formed on the support main body 2 are combined. It can be molded and used integrally. In this way, when assembling the push-down member,
There is an advantage that handling becomes convenient. It goes without saying that such an integrated type of the support body and the end holding piece also belongs to the category of the present invention. Further, the outer shape of the support body is not limited to the above-described embodiment, and may be a cylindrical shape as needed.
