BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a punching waste separation type drop-out support used mainly in a process of manufacturing a blank such as a paper container by punching a material sheet such as cardboard or paperboard.
[0002]
[Prior art]
When punching a material sheet such as cardboard or paperboard to produce a paper container, the material sheet is punched into a required shape by a punching die, and the part that becomes a product from the material sheet punched in the next process A portion that becomes a so-called scrap is removed by a punching scrap separator.
[0003]
Conventionally, in such a punching apparatus, for example, as shown in FIG. 4, a portion that becomes punching waste other than the product portion 102 is formed from a material sheet 100 in which a punching process is performed to form a punching line 101. For separation, the normal product portion 102 and the portion 103 that becomes the scrap are provided with a plurality of narrow connecting portions 104 at appropriate intervals in order to shift from the punching step to the next punching waste separation step. It can be moved to the punching waste separation process. Therefore, as a punching waste separation mold used in the punching scrap separation device, for example, as shown in a perspective view showing an example of a conventional punching separation type in FIG. 5, a product from the material sheet 100 on which the punching line 101 is formed is shown. In order to separate the portion 102 and the portion 103 that becomes the scrap from the product forming portion, the lower mold 110 that is slightly smaller than the outer shape of the product forming portion and the portion that becomes the scrap other than the product are separated from the product forming portion. In this case, a pair of upper mold 111 and scraper dropping member 113 having an inner peripheral edge with a slightly larger shape than the product forming portion that receives lower mold 110 is used.
[0004]
The upper part 111 of the scrap-separated mold has a required height from the substrate 112 in order to separate the product portion 102 from the material sheet 100 on which the punching line 101 is formed by the cooperative action with the lower mold 110. A scrap dropping member 113 is projected in a required position at a required size. In the figure, reference numeral 114 denotes an elastic body for separating dust, which is made of a sponge material provided at an appropriate position within the range surrounded by the scraping 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 a watermark hole for releasing the air resistance generated between the upper and lower molds that are closed during the scrap separation operation.
[0005]
[Problems to be solved by the invention]
In such a punching waste separation type, generally, a metal strip member is bent as the punching scraping member 113 according to the shape of the punching product part and is implanted into the substrate, and processing work by a skilled worker is performed. This requires not only a lot of work, but also requires the preparation and processing of the scrapping member 113, which increases the construction cost.
[0006]
Because of this, recently, when manufacturing the lower mold, it is cut out using a laser beam according to the shape of the punched product part. A punching waste separation type focused on making it a drop-off member has been proposed and can be rationalized. In such a punching waste separating mold, particularly the upper die, as shown in the front view showing the upper die of the punching waste separating type in FIG. By using the remaining part after the lower mold is created, the upper mold 10 and the lower mold 11 (see FIG. 3B) are used to remove the product part along the punching line from the punched material sheet. (The plan view is shown) can be directly fitted. In order to do this, a scraping member 13 having a required size is removed from the surface of the substrate 12 of the upper mold 10 (it is formed of a plurality of pieces depending on the shape. Must be mounted in a floating state. For this purpose, the scrap drop member 13 is attached to the surface of the substrate 2 with countersunk bolts (not shown) with a spacer 14 interposed. Of course, the chipping-off member (not shown) other than the part that removes the outer periphery of the product part is also formed on the board surface (plywood) with an outer shape corresponding to the shape, and attached to the substrate surface with a spacer interposed It has been. In the figure, reference numeral 17 is an elastic body, and 18 is a watermark hole.
[0007]
In such a punching waste separating mold, for example, when the outer peripheral portion is separated as it is when separating and removing the removed portion along the outer peripheral portion of the product portion from the material sheet on which the punching line is formed, Since it is a large piece of waste having a bent portion in a state surrounding the product portion, it is inconvenient in subsequent handling, so that the piece of waste is further divided and separated when it is removed. Therefore, in the punching waste separating mold, scraping cutting blades 16, 16 ′ are attached to the lower die 11 at a required location, and the cutting blade 16, At positions corresponding to 16 ', slits 15 and 15' for receiving the cutting blades 16 and 16 'are provided, and the cutting blade 16 (16') and the slit 15 (15 ') are removed by the cutting blade separating operation. It is designed to cut trash.
[0008]
However, if the scrap separation / removal operation is repeated, the scrap scraping member 13 is provided at a place where the scrap cutting operation is performed by the cutting blade 16 (16 ') and the slit 15 (15'). The edge part of the slit forming part is damaged and the chip is broken simultaneously with the cutting of the chip during the cutting operation to generate a lot of paper dust, thereby deteriorating the working environment. For this reason, there is a problem that not only the working environment is deteriorated but also paper dust adheres to the product portion and moves. In addition, there arises a problem that the scrap member dropping member 13 is severely damaged at a portion that is easily affected by an impact force such as a corner portion.
[0009]
The present invention has been made to solve the above-mentioned problems, and in particular, effectively improves the scrap disposal at the location where the problem is likely to occur, and supports the scrap dumping member against the substrate. It is an object of the present invention to provide a punching-separation-type drop-off member support that has a function of making it possible to improve durability as a punching-separation-type.
[0010]
[Means for solving the problems and actions / effects]
In order to achieve the above-described object, the punching waste separating type protruding member support according to the present invention includes:
This is a punching waste separation type punching member support tool that supports the punching scraping member of the required shape while maintaining the required height position from the surface of the substrate. As a support tool disposed at the receiving location, an engagement protrusion that engages and positions a scraping protrusion member on a receiving surface opposite to the mounting side of the support body with respect to the substrate, and a scraping member that receives and supports And an end holding piece that stands upright along the side edge of the side, and is configured so that the upper end of the end holding piece protrudes appropriately from the top surface of the cutting piece protruding member in a state in which the cutting piece protruding member is supported. It is characterized by being.
[0011]
According to the present invention, the punching scrap separation type plywood punching scraping member functions to support the substrate surface on the substrate surface at a predetermined height, and receives a large local load at the time of scraping cutting operation, For example, because it is used by placing it at the slit forming part or corner part facing the cutting blade, etc., against the load that is locally received by the cutting of the material sheet by the cutting blade on the lower mold side or the periphery of the template, At this position, the upper end portion of the end holding piece is made to come into contact with the top surface of the scraped member before the material sheet comes into contact therewith, so that the lower die side is cut off by the upper end portion of the end holding piece. By receiving the pressing force from the blade or the peripheral edge of the template, it is possible to reliably cut off the connecting portion and the cutting portion along the punching line. At the same time, the edge holding piece protects the edge of the scrap falling member. Therefore, there is an effect that it is possible to improve the durability by preventing the scrapping member from being dropped and enhancing the durability and eliminating the generation of paper dust due to the damage.
[0012]
The end holding piece is formed of a metal plate, is supported by a scraping member receiving surface of the support body, and is parallel to the axis of the engaging projection standing upright on the receiving surface, and has a required dimension from the engaging projection. It should be formed upright with a dimension longer than the thickness of the scraping-off member that is received and supported at a distance. In this case, if the positioning protrusions of the support body are positioned so that the engagement protrusions of the support body are engaged with the engagement holes of the predetermined support positions of the extraction protrusion members, the extraction protrusion members are arranged. At the same time, the upright portion of the end holding piece is arranged along the end surface of the scraping member, and the scraping member of the scraping member is removed from the external force by the sheet to be processed at the time of the scrap separation operation. The edge can be protected. And, the upright end portion of the end holding piece made of a metal plate is dropped from the scrap and protrudes from the surface of the member, so that the sheet is displaced by being concentrated and receiving a load when the scrap is divided. It is possible to prevent the scraps from being cut off smoothly.

DETAILED DESCRIPTION OF THE INVENTION
Next, a specific embodiment of the punching waste separating type dropping member support according to the present invention will be described with reference to the drawings.
[0014]
FIG. 1 shows an overall perspective view of the dropping member support of the present embodiment, and FIG. 2 shows a partial perspective view of a punching waste separating type provided with a protruding member supported by the support of the embodiment. It is shown.
[0015]
The projecting member support 1 of the present embodiment has a required length that is projected from the center of the upper surface and the lower surface of the support body 2 in a cubic shape with a required external dimension and the same axis. The columnar engagement protrusions 3 and 4 and an end holding piece 6 that is bent and formed on one side supported by the upper surface 5 of the support body 2.
[0016]
The support body 2 is integrally formed with, for example, plastic together with the engagement protrusions 3 and 4, and a protruding member (corresponding to a scraped protruding member of the present invention) that supports the upper surface 5 and the lower surface 5 'in parallel. ) Is set to a predetermined height on the upper mold surface. Further, the height dimensions h ′ and h ″ of the engaging projections 3 and 4 are set to be slightly shorter than the thickness dimension of the plywood forming the substrate and the chipped-off member. Stopping projections 8 are provided on the side edges downward.
[0017]
Further, the end holding piece 6 is formed by bending a thin plate of, for example, a stainless steel plate into an L shape, and the thickness of the scraping member 13 that is placed on and supported by the upper surface 5 of the support body 2. The upright portion 6a is formed to be slightly higher than the length t, and a hole 7 through which the engaging projection 4 is inserted is provided in the portion 6b received on the upper surface 5 of the support body 2. A distance s from the center of the hole 7 to the inner surface of the upright portion 6a in a state where the engaging protrusion 4 is inserted is in contact with the end surface of the protruding member 13 supported.
[0018]
The protruding member support 1 of the present embodiment formed in this way has the scraping member 13 provided on the punching separated type upper mold 10 as shown in FIG. It serves as a spacer to be mounted at a required height, and is used particularly as a support portion at a portion of the dropping member 13 where the cutting blade receiving slits 15 and 15 'are formed, a corner portion, or the like.
[0019]
In order to mount the protruding member support 1 on the substrate 12, first, a mounting hole is formed in the substrate 12 at a predesigned position, and the support of the protruding member support 1 is inserted into the mounting hole. The main body 2 projecting engagement protrusion 3 is fitted and attached. At this time, it is preferable that the fitting between the mounting hole and the engaging protrusion 3 is such that the fitting can be tightly fitted. Further, when the support body 2 is mounted on the substrate 12, the orientation can be determined by providing and fitting small holes for engaging the rotation protrusions 8 on the lower surface. After the support body 2 is mounted on the surface of the substrate 12 in the required distribution in this way, the end holding piece 6 is placed on the upper surface 5 of the support body 2 and the supported portion 6b is formed in the hole 7. The engaging projections 4 are fitted together and placed at a position where the upright portion 6a is vigorously subjected to punching waste cutting operation, for example, a slit 15 (15 ') forming portion (see FIG. 2).
[0020]
After that, the dropping member 13 is supported by the support tool 1 so that the upward engagement protrusion 4 of each support tool 1 is fitted in a pre-drilled positioning engagement hole. Then, it is fixed to the substrate 12 with a countersunk head bolt 18. In addition, even if it is except the above-mentioned corner part and slit formation part, it can attach so that the upright part 6a of the edge part holding piece 6 may be along a cutting operation edge in the part along a punching line.
[0021]
The protruding member 13 mounted on the substrate 12 in this manner is an end surface where the conditions for acting on the protruding member 13 are not good in the separation operation of the punching waste by the upper mold 10 and the lower mold 11. The end is surrounded by the upright portion 6a of the end holding piece 6 and the tip of the upright portion 6a of the end holding piece 6 protruding from the surface of the protruding member 13 protrudes into the material sheet provided with the punching line When the contact member 13 comes into contact (when the cutting blade 16 cuts the material sheet in a positional relationship with the slit 15), first, the tip of the upright portion 6a of the end holding piece 6 comes into contact and bites into the material sheet. To do. Therefore, when the surface of the dropping member 13 or the cutting blade 16 is cut, the material sheet is surely divided without causing a shift. Further, the end holding piece 6 is dropped by the side surface of the upright portion 6a, and the contact resistance due to the scraps acting on the heavily loaded end portion of the member 13 is directly dropped and does not act on the end of the member 13 without being separated and damaged. This can be prevented.
[0022]
As described above, according to the punching member dropping tool support 1 of the present embodiment, the problem in the conventional punching waste separating mold is solved, and the protruding member made of plywood is attached to the substrate with the spacer interposed therebetween. In this type, the effect excellent in solving the problem can be exhibited, and a better effect can be obtained.
[0023]
In the above embodiment, the combination of the end holding pieces 6 formed separately on the support body 2 has been described. However, although the metal end holding pieces are not shown, they are integrated with the support body. It can be formed and used. If it does in this way, when assembling a dropping member, there exists 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. Moreover, about the external shape of a support tool main body, it is not limited to the said Example, It can also be set as a column shape as needed.
