Description

The present invention relates to a surface plate for a sheet punching die, and more particularly to a surface plate for a sheet punching die used for punching a sheet so as to have an outer shape of a paper container and providing a crease and a perforation, and a sewing machine using the surface plate. The present invention relates to a method for forming a weighted sheet.

Paper containers (packaging containers, paper boxes) that are formed by punching, folding, and bonding sheets made of paper or a composite material of paper and resin, metal, etc. are lightweight and convenient to carry. It is widely used in many industrial fields such as the parts industry and the automotive industry.

A number of paper containers are being formed with perforations (cut-out dotted lines, cut-out broken lines). For example, in a display case for displaying a plurality of confectionery, in the middle of the paper container, two perforations 111 are formed in parallel along the outer periphery to form a zipper (opening belt) 150, and the zipper 150 is opened to remove the paper container. There is known a paper container that is opened to separate the lower side and the upper side of the paper container so that confectionery and the like stored in the paper container can be seen (see FIG. 21). For example, in a tissue box or tea parcel box, a perforation 111 that circulates on the side of the paper container is formed to form a surrounding part 160, and this surrounding part 160 is cut off to create a takeout opening in the paper container, which is then placed in the paper container. A paper container is known which serves as a take-out port for taking out a tissue or a package (see FIG. 22). Inside the enclosure 160, a valley-fold ruled line (folding line) 102b is formed to facilitate the separation of the enclosure 160 by pushing the inside of the perforation 111 from above. As the external shape of these paper containers, there are a quadrangular column, a hexagonal column, an octagonal column, a cylinder, and the like, and various three-dimensional paper containers are designed.

FIG. 16 shows the relationship between the conventional surface plate 200, the sheet 100, the punching die 22 and the receiving die 21. A conventional punching die 22 is used for punching a sheet 100, and performs laser processing on a plywood board according to an outer shape to be a paper container, a ruled line for folding, or a perforation, and a punching blade 26 corresponding to the outer shape to be a paper container. Forming a groove for cutting, a groove for the cutting blade 24 and a groove for the ruled member 25, a punching blade 26 in each groove, and a cutting blade 24 having the same height as the punching blade 26. The stamping member 25 having a smaller height than the punching blade 26 and the cutting blade 24 is embedded, and the protruding amount of the stamping member 25 downward is smaller than that of the punching blade 26 and the cutting blade 24. Produced as a protruding amount.

In the punching process, the sheet 100 is inserted between the punching die 22 mounted on the upper side of the punching machine 19 and the receiving die 21 on the lower side of the punching machine 19, and the receiving die 21 is raised and then lowered. Then, punching is performed (see FIG. 16). In other words, the punching blade 26 cuts into a predetermined shape, the cutting blade 24 cuts a perforation, the ruled member 25 engraves a plurality of crease lines 101 at a required portion, and a blank (punched sheet) 100 is formed. Form. Next, a paper container is assembled by folding the valley along the crease 101 of the blank 100 and bonding the paste margin together.

In the conventional punching die 22 shown in FIG. 16, when punching the sheet 100 and applying the folding line 101, the groove 201 is formed at a position corresponding to the ruled member 25 in order to engrave the folding line 101 more accurately. The formed face plate 200 is attached to the upper surface 21 a of the receiving die 21 of the punching machine 19. That is, by forming the predetermined groove 102 in the face plate 200, the sheet 100 pushed downward by the ruler member 25 forms a predetermined line 102b (convex shape in FIG. 16). By forming the convex line 102a on the opposite side of the folding line 102b, damage to the blank 100 is reduced by the ruled member 25, and the blank 100 is easily bent. When the perforation 111 is inserted into the sheet 100, a gap or a through-hole having a predetermined width that is large enough to pass the entire cutting blade 24 is formed at the position where the perforation 111 is to be inserted. This is because forming a large number of small gaps and through-holes corresponding to the cutting blades 24 for making the respective cuts of the perforation 111 in the surface plate 200 takes a lot of labor, and the cutting blades for making the respective cuts. Since it is extremely difficult to align the gap 24 and the through hole 24 with each other, the gap can be aligned by forming a gap or a through hole having a predetermined width large enough to pass the entire cutting blade 24. For this reason, when the gap or the through hole having the predetermined width is formed in the surface plate 200, the surface plate 200 is divided (see FIG. 16).

The surface plate 200 is composed of a plate-like or film-like substrate, and recently, a surface plate that can be reused by being applied or peeled off by applying an adhesive to the back surface of the substrate has been on the market. (See Patent Document 1). These face plates 200 are made of synthetic resin such as ABS, PBT, PPS, phenol resin, etc., and positions corresponding to the ruled members 25 of the punching die 22 by the NC processing machine from CAD data for manufacturing the punching die 22. The groove 102 is cut and processed so that the portion where the punching blade 26 abuts is cut off to the outer periphery, and the face plate 200 is divided so that the cutting blade 24 does not abut (FIG. 20). Etc.). As a method for attaching the face plate 200 to the receiving die 21, for example, there is a method shown in Patent Document 2, in which a transfer positioning jig 29 is removably inserted into a positioning hole of a punching die (male die). Then, the transfer member 12 is transferred onto the receiving mold 21 and aligned so that the outer periphery of the transfer member 12 becomes a through hole 212 provided in the surface plate 200, and an adhesive is applied to the upper surface 21 a of the receiving mold 21. A method of bonding is known (see FIGS. 19 and 20).

For example, when punching the sheet 100 on which the perforation 111 to be the zipper 150 shown in FIG. 4 is punched and providing the crease 102b and the perforation 111, as shown in FIG. A gap with a predetermined width large enough to pass the entire cutting blade 24 for forming the perforation 111 to be formed is formed, and the face plate 200 is divided into the face plate 201 and the face plate 202. To be bonded to the upper surface 21a of the receiving die 21. When the surface plate 200 is divided, the groove 102 that receives the convex line 102b having a predetermined shape is formed in the middle when the sheet 100 pressed downward by the ruled member 25 for forming the concave folding line 102b on the sheet 100 is in the middle. Therefore, it is necessary to make up for the groove 102 that has been cut off and missing, and after adding the small pieces 203, 204, 205, and 206 having the crease forming groove 102 to make up the groove 102 that has been cut off and missing, The dividing portion of the groove 102 is set to a minimum size. These small pieces 203, 204, 205, and 206 are processed using the base material of the face plate 200 and bonded to the upper surface 21 a of the receiving mold 21, or a pair of left and right base material small pieces such as a tape is provided at a predetermined interval. The substitute material that is bonded to the bonding means is bonded to the upper surface 21a of the receiving mold 21 (FIG. 17).

Further, for example, when punching the sheet 100 on which the perforation 111 to be the enclosing portion 160 shown in FIG. 12 is punched and applying the crease 102b and the perforation 111, as shown in FIG. A through-hole having a size sufficient to pass the entire cutting blade 24 for forming the perforation 111 that circulates around the surface is formed, and the face plate 200 has an upper surface of the receiving die 21 with the through-hole 190 opened. Bonded to 21a. When the through hole 190 is opened in the face plate 200, the groove 102 that receives the convex line 102b having a predetermined shape when the sheet 100 pressed downward by the ruler member 25 for forming the concave crease 102b in the sheet 100 is formed. Therefore, the missing groove 102 needs to be compensated, and small pieces 207 and 208 having the crease-providing groove 102 are retrofitted to supplement the missing groove 102 and the crease-giving groove 102 is regenerated. These small pieces 207 and 208 are processed using the base material of the face plate 200 and bonded to the upper surface 21a of the receiving die 21, or a pair of left and right base material pieces are bonded to an adhesive means such as a tape so as to have a predetermined interval. Then, the substitute is substituted on the upper surface 21a of the receiving mold 21 (FIG. 18).

As described above, conventionally, under the condition where the perforation 111 of the sheet 100 intersects with the folding line 102b, the groove 102 that receives the convex line 102b having a predetermined shape when the sheet 100 pressed downward by the ruler member 25 is used. Therefore, the small pieces 203, 204, 205, 206 and the like having the crease-growing groove 102 are retrofitted and supplemented so that the dividing portion of the groove 102 is minimized. Further, conventionally, since the sheet 100 pressed downward by the ruled member 25 under the condition that the perforation 111 of the sheet 100 straddles the folding line 102b, the groove 102 that receives the convex line 102b of the predetermined shape is lost. The small pieces 207, 208 and the like having the folding line applying groove 102 are retrofitted and supplemented to regenerate the folding line applying groove 102.

However, when the surface plate 200 is divided, it becomes a plurality of surface plates 201, 202 and the like, and it is difficult to attach and align the receiving plate 21 (see FIG. 20). In addition, the surface plates 203 to 208, etc., which have become small pieces, have a small adhesive area, so that the adhesive force is weakened and easily peeled off during operation, so that a large number of sheets can be punched out in a short time. It is hard to say that the reliability is sufficient. In addition, since the surface plate 200 is a combination of a large number, the replacement is also complicated. In particular, when the perforation 111 goes around the paper container 100 (FIG. 4) or when the folding line 102b is formed inside the turning perforation 111 (FIG. 12), the surface plate 200 is divided into a plurality of parts. Since the small pieces are formed in a small amount, the face plate 200 becomes a mosaic shape, and bonding to the receiving mold 21 becomes a complicated operation.

Accordingly, an object of the present invention is to provide a surface stencil for a sheet punching die and the surface stencil without the need to divide the surface plate or dispose a small piece having a crease forming groove when the perforation is applied to the sheet. It is an object of the present invention to provide a method for forming a perforated sheet.

The surface plate for a perforated sheet punching die according to the present invention includes a punching blade for punching a sheet, a ruler member for imparting a crease to the sheet, and a punching die provided with a cutting blade for cutting a perforation in the sheet, A punching plate to which the punching die and the receiving die for receiving the sheet are attached is used for punching the sheet so as to have the outer shape of the paper container and attaching the folding line and the perforation to the receiving die for use. And on the surface plate substrate, a perforation groove for receiving the cutting blade and a crease groove for receiving the ruler member are formed,
A perforation groove is formed on the substrate so as to intersect with the crease groove, or a perforation groove is formed across the crease groove on the substrate, at least The substrate is connected at a position where the perforation groove is formed.

According to the present invention, the perforation groove is formed on the substrate so as to intersect the crease groove, or the perforation groove is formed across the crease groove on the substrate. Since the substrate is connected at least where the perforation groove is formed, it is not necessary to divide the substrate, and it is not necessary to arrange a small piece having a crease groove Become. Therefore, the perforation forming operation is easy and the surface plate can be easily aligned, pasted, and replaced.

The said surface plate consists of a board | substrate of a plate shape or a film form, and is good also as a surface plate which can be reused by sticking or peeling off by apply | coating an adhesive agent to the back surface of a board | substrate. The surface plate is made of a synthetic resin such as ABS, PBT, PPS, or phenol resin. And according to the present invention, since the face plate is not divided for the formation of perforations, it is possible to manufacture a sheet that becomes one paper container having a perforation using a single face plate. I can do it.
That is, the perforated sheet forming method of the present invention includes a punching blade for punching a sheet, a ruler member for applying a crease to the sheet, and a punching die provided with a cutting blade for cutting a perforation in the sheet, A sewing machine that is used by punching a sheet so as to have the outer shape of a paper container and attaching a face plate to the receiving mold when a punching machine having a punching mold and a receiving mold that receives the sheet is attached. In the method for forming a weighted sheet,
When punching a sheet as a paper container and applying a crease and a perforation, the surface plate is a single surface plate, and a perforation is received on the substrate of the surface plate by the cutting blade. A crease forming groove to be received by the groove and the ruler member is formed;
A perforation groove is formed on the surface plate substrate so as to intersect with the crease groove, or a perforation groove is formed across the crease groove on the substrate, A perforation is formed on the sheet in a state in which the surface plates are connected at least at a place where the perforation giving groove is formed.

In the present invention, it is preferable that the depth of the crease providing groove and the depth of the perforated groove are set to be the same. By setting the depth of the crease-providing groove and the depth of the perforation-providing groove to be the same, groove processing is facilitated, and the height dimension of the cutting blade and the height dimension of the ruled member Since the amount of protrusion downward of the cutting blade is the same as the amount of protrusion downward of the ruled member, the height of the material of the punching blade, the cutting blade and the ruled member is high. There are fewer types of size. In the present invention, the height dimension of the cutting blade is set to be smaller than the height dimension of the punching blade, and the downward protrusion amount of the cutting blade is set to be a protrusion amount smaller than that of the punching blade. preferable.

In the present invention, when forming a zipper-type perforation in which a perforation is arranged in parallel in a sheet, is there at least two perforation grooves formed on the substrate so as to intersect with the crease formation grooves? Alternatively, at least two perforation grooves are formed on the substrate across the crease groove, and a crease groove is provided between the one perforation groove and the other perforation groove. It is formed.

According to the present invention, for example, it is easy to form a zipper perforation. That is, the perforation groove is formed at the position intersecting with the crease groove, so that a perforation can be formed around the paper container. Two perforations can be formed to form a zipper (opening belt). And the zipper can be opened to separate the lower side and the upper side of the paper container. In addition, for example, it is easy to form a surrounding portion that becomes a take-out port. That is, by forming the perforation groove on the substrate across the crease provision groove, it is possible to form a perforation that surrounds and surrounds the side surface of the paper container. By forming a crease formation groove between the perforation formation groove and the other perforation formation groove and providing a valley fold ruled line (fold line), the inside of the perforation is pushed from above to cut off the surrounding portion. The structure can be made easier. These paper containers include quadrangular columns, hexagonal columns, octagonal columns, cylinders, and the like, and various three-dimensional shapes are designed.

In the present invention, a plurality of fold lines are arranged on the sheet, and when forming a sheet with a perforation between one fold line and the other fold line, A through hole that connects the intersecting perforation groove and the perforation groove intersecting with the other fold line is formed so as to surround the perforation to be spread.

Although it is not easy to accurately align the cutting blade and the perforation groove in the wide range between the crease provision groove and the crease provision groove, According to the invention, a through hole that connects the perforation groove and the perforation groove is formed on the substrate at a position where the perforation crosses between the crease lines of the sheet. Thus, it is possible to easily make a perforation by projecting the cutting blade that will be located inside the through hole. The perforation is a zipper, and the zipper is opened to open the bottom of the paper container. In order to separate the upper side, a suitable structure is obtained.

In the present invention, it is preferable that a taper process for controlling a pressing direction of the cutting blade is performed on an upper surface side of the through hole. When perforating the sheet in contact with the face plate, there is a concern that the sheet is pressed and scratched on the edge portion on the upper surface side of the through hole on the substrate, but according to the present invention, Since the edge portion is obliquely removed by applying a taper process to the upper surface side of the through hole, the pressing direction of the cutting blade is used when perforating the sheet in contact with the face plate Therefore, there is no concern that the sheet is pressed against the edge portion on the upper surface side of the through hole on the substrate and scratched.

According to the present invention, on one substrate, a crease forming groove for receiving the ruled member with the sheet interposed therebetween is formed, and a perforation providing groove for receiving the cutting blade with the sheet interposed therebetween is formed. As a result, the surface plate is not divided, so it is easy to bond to the receiving mold and is bonded at an accurate position. There is no need to divide the plate or dispose a small piece having a crease-grooving groove, and there is no possibility of peeling off due to impact or the like during operation, and the surface plate can be easily replaced. According to the present invention, a through hole that connects the perforation groove and the perforation groove is formed on the substrate at a position where the perforation crosses between the crease lines of the sheet. Thus, the cutting blade that will be located inside the through hole can be easily protruded to be surely perforated, and the perforation can be used as a zipper. In order to separate the upper portion from the upper portion, a suitable structure is obtained. Therefore, it is used when punching a sheet to form the outer shape of a paper container and giving creases and perforations, and a structure that can be easily replaced while ensuring the reliability required to punch a large number of sheets in a short time This is the face version.

When this sheet is assembled, the surrounding portion 160 is cut along the perforation 111 formed on the side surface of the paper container, and a takeout opening is created in the paper container, thereby providing a takeout opening for taking out the contents stored in the paper container. (FIG. 12). According to the present embodiment, the perforation giving groove 11 is formed around the fold line giving groove 102 on the substrate 2 so that the one perforation giving groove 11 and the other perforation are formed. A structure that makes it easy to separate the surrounding portion 160 by pushing the inside of the perforation 111 from above by forming the crease forming groove 102 between the crease forming groove 102 and the valley fold ruled line (folding line) 102b. It can be.

The base material of the face plate 1 in the first embodiment and the second embodiment described above is preferably made of a plate-like or film-like resin, and more specific materials include ABS, PBT, PPS, phenol resin, Examples include synthetic resins such as polyethylene, polypropylene, and polycarbonate. This is not only easy to process, but also easy to deform to bring the face plate 1 and the roller 29 into close contact with each other in the case of a cylindrical (roller-shaped) receiving die 29 as well as the flat receiving die 21. It is set from the viewpoint of safety and can be easily attached to a rotary punching machine (see FIG. 15).

In the present embodiment described above, the outer periphery of the substrate 3 in the face plate 1 is smaller than the punching blade 26 so that the punching blade 26 does not directly hit from above. It is good also as a structure which forms the groove | channel deeper than the crease | folder provision groove | channel 102 and the perforation provision groove | channel 11 in the position received by, and escapes the blade edge | tip of the punching blade 26. FIG. Instead of the through hole 13, a dent deeper and wider than the crease providing groove 102 and the perforation providing groove 11 may be formed. Thus, it goes without saying that the present invention can be modified as appropriate without departing from the spirit of the present invention.
