Description

  The present invention is provided with a cutting blade and a ruled line blade to form a crease line and the like at the same time as cutting and separating the container material assembled as various packaging containers made of, for example, paperboard, corrugated paper, and transparent synthetic resin sheet from the sheet material. Folding ruled line forming plate in a packaging container punching machine that can be used to attach a folded ruled line forming plate used together with a die mold to a cutting plate surface by accurately aligning the cutting line part and the ruled line part. The present invention relates to a mounting method and a mounting jig.

  Conventionally, when forming a container material to be a predetermined packaging container from various sheet materials such as paperboard, corrugated cardboard, plastic, etc., in order to perform punching processing of the container material, In order to form ruled line grooves, cutting line grooves and the like corresponding to the cutting lines and the like, a so-called face plate corresponding to these is prepared. Then, this surface plate is pasted on an iron plate cutting plate which can be pasted in a machine such as Orton, and a wooden die having a ruled line blade and a cutting blade opposite to the ruled line, cutting line, etc. in the surface plate. By punching from the sheet material with a mold, the sheet material part is formed with a crease line in the shape of a streak, and the periphery is punched and formed as a container material that is cut and separated along the outline of the container material. Yes.

  As the surface plate for forming the folding ruled lines at this time, for example, a so-called CAD surface plate formed by NC processing a heavy stainless steel plate or the like in addition to a resin surface plate such as bakelite or PP is used. A CAD surface plate is affixed on a cutting plate, and a die-type ruled line blade is inserted into the groove portion to form a crease portion, and the outer shape of the container is punched out by cutting with a cutting blade.

  By the way, when this folded ruled line forming surface plate is pasted on the cutting plate, it is necessary to accurately position and paste the groove so that the groove portion corresponds to the position of the die type ruled line blade and cutting blade. . For this reason, conventionally, the upper and lower surfaces of the die mold are inverted with respect to the upper die mold that moves up and down on the lower cutting plate to which the face plate is fixed, for example, and at least two locations of the die mold are used. The guide rod is inserted into the fitting hole opened in the upper side and placed upright. Then, when positioning the folded ruled line forming surface plate on the basis of the position of the guide bar, the folded ruled line forming surface plate is aligned with the groove of the folded ruled line forming surface plate at the position of the die-shaped ruled line blade. In this case, a fitting hole corresponding to the position of the guide bar is formed, and the face plate is temporarily fixed to the die mold by forcibly fitting the fitting hole to the guide bar.

  With the position of the groove portion and the position of the ruled line blade aligned with each other, the die mold is turned upside down again to attach the die mold to the lifting part of the elevator, and then the die mold is used as the cutting plate by the ruled line blade. The folding ruled line forming surface plate attached to the guide rod is pasted on the cutting plate by being lowered to the abutting position. Thereafter, the sheet material is put on the surface plate on the cutting plate, and for example, an assembly container material having a predetermined outer shape with a crease formed by a ruled line blade is obtained from the sheet material by the vertical movement of the die.

  However, the folding ruled line forming surface plate attached to the die mold by the guide rod standing upright in the die mold in this way, when the die mold is turned upside down and attached to the lift part of the elevator, The folded ruled line forming surface plate is hung downward by the guide bar. Then, for example, if it is a large size surface plate, it may be bent slightly downward due to its own weight, and when positioning and pasting the surface plate on the cutting plate by the die lowering operation, If the bent portion is pasted first, distortion may occur as a whole, or the position of the die-type ruled blade and the position of the groove portion of the folded ruled line forming face plate may be misaligned with each other. .

  In addition, when the weight of the surface plate itself is relatively large, such as the above-described heavy stainless steel surface plate, the guide is used when turning the die mold upside down and attaching it to the lifting part such as an elevator. If there are few places supported by the bar, the surface plate itself cannot withstand the weight and may fall from the guide bar or die die together with the guide bar. In addition, the support position of the guide rod for positioning the surface plate with respect to the die mold needs to avoid the position of the cutting blade and the ruled line blade in the die mold, or the position of the ruled line groove portion serving as the crease position in the surface mold, Since there are considerable restrictions on the arrangement and number of guide bars, it is difficult to increase the number of guide bars installed more than necessary.

  On the other hand, there have been proposed a die-cutting to a punching machine, a female die-attaching method and die-cutting, and a female-type positioning attachment member shown in Patent Document 1. This is because when a die and a female die are aligned and attached to the upper and lower press plates, a positioning pin that can be inserted and removed is inserted into a positioning hole provided in the die, while a female die corresponding to the die positioning hole is also positioned. A hole is provided, a positioning disk that can be fitted to the head of the positioning pin is mounted, and then the die is attached to the upper press plate. The upper press plate is pressed against the lower press plate, and the positioning disk is attached to the lower press plate. Assume that the female die is attached to the lower press plate by attaching the positioning hole to the positioning disc plate and attaching the female die to the lower press plate.

Japanese Unexamined Patent Publication No. 7-171895

  However, according to the mounting method and mounting member according to the conventional patent document 1, in order to attach the positioning disk to the positioning pin, the recess provided in the positioning disk is fitted to the head of the positioning pin. Even if it is mounted by applying a viscous material, there is a possibility that only the positioning disk falls when the upper press plate is placed in the upper position and pressed against the lower press plate in the lower position. Further, when the female die is fitted to the positioning disk and fixed on the female die and the material is punched out, the material may be soiled by the grease. In order to prevent the contamination, it is very troublesome even if the positioning disk is cleaned in advance or only the positioning disk is removed after positioning and fixing.

  Moreover, if the positioning disk itself is used together with the female die on the lower press plate, it needs to be approximately the same as the wall thickness of the female die. When the thickness is about 0.3 to 0.5 mm, it is not possible to secure a sufficient depth to ensure the fitting of the positioning focus to form the recess. Further, even if the positioning pin for fitting and holding the positioning disk is inserted in the mold so as to be detachable, the insertion hole needs to be uniquely formed, and the forming process is troublesome.

  Therefore, the present invention was created in view of the conventional circumstances as described above, and a guide member is erected on a die mold opposite to the cutting plate, and is aligned to the guide member position. This is a surface that corresponds to the ruled line blade and cutting blade position in the die mold, so that the surface plate can be fixed to the cutting plate surface by aligning and affixing it to the cutting plate surface. Ensure that the plate can be installed correctly. In addition, the die mold has a die-shaped ruled line blade that does not directly attach a surface plate for forming a folded ruled line such as a heavy or large size that may fall or bend. A mounting method and a mounting jig for a folded ruled line forming plate in a packaging container punching machine, in which the surface plate can be fixedly arranged on the cutting plate so as to be surely positioned corresponding to the position of a cutting blade, etc. The purpose is to provide.

In order to solve the above-described problems, the method of attaching the folding ruled line forming surface plate in the packaging container punching machine according to the present invention is based on the cutting blade 11 of the die 10 and the ruled line corresponding to the assembly such as the packaging container. When the surface plate 1 for forming a cutting line and a crease ruled line on the sheet material P together with the blade 12 is fixed to the cutting plate 20, the guide member is disposed so as to protrude in at least two locations of the die mold 10 facing the cutting plate 20. The step of opening the positioning opening 33 for positioning having a predetermined shape centered on the position of the guide member 40 with respect to the position of the guide member 40 in the face plate 1, and the outer shape along the shape of the positioning opening 33 in, the guide member 40 disposed mounting jig 30 fitted to form a thickness of approximately the same as the surface plate 1 thickness to the positioning opening 33 in the die mold 10, open to the mounting jig 30 Forcibly mounted by fitting with the formed fitting holes 31, the step of attaching the fixture 30 to the cutting plate 20 surface by moving the die mold 10 to the position of the cutting plate 20, cutting plate 20 side of the And the step of fixing the surface plate 1 to the cutting plate 20 by fitting the positioning opening 33 of the surface plate 1 into the mounting jig 30 so as to be matched with each other.
Furthermore, the guide member 40 is slidably inserted into the die mold 10, and can include a step of removing the guide member 40 from the die mold 10 after the attachment jig 30 is attached to the surface of the cutting plate 20.
Further, the mounting jig for the folded ruled line forming plate in the packaging container punching machine according to the present invention forms cutting lines and crease ruled lines on the sheet material P together with the die mold 10 corresponding to the assembly. intended to fix the surface plate 1 to the cutting plate 20, the die surface plate 1 of the border grooves 2 and cutting an outer edge 3 to the position of the ruled line blades 12 and the cutting blade 11 of the die mold 10 into the cutting plates 20 fit respectively so that let align the mold 10, which has a fitting hole 31 to fit freely forcibly fitted desorbed guide member 40 is protruded arranged in at least two places of the die mold 10, which is formed on the surface plate 1 positioned An outer shape along the opening shape of the positioning opening 33 is exhibited so that the opening 33 can be fitted.
The mounting jig 30 can be formed in a circular flat plate shape with a thickness approximately the same as the thickness of the face plate, and the mounting jig 30 includes a guide member 40 of the die mold 10. The rebound member 50 can be configured to be interposed between the die mold 10 and the die mold 10 when they are fitted together.
An adhesive means 35 to be bonded to the surface of the cutting plate 20 is formed on the surface of the mounting jig 30, and the release paper 34 can be formed on the surface of the adhesive means 35 so as to be peeled off.
Further, the mounting jig 30 can be formed by punching out the surface plate 1 in a predetermined shape, and forming the punched-out portion after the punched-out formation as the positioning opening 33.

In the mounting method and the mounting jig of the folding ruled line forming surface plate in the packaging container punching machine according to the present invention configured as described above, it is fitted and attached to the guide member 40 protruding from the die 10. When the mounting jig 30 is affixed to the surface of the cutting plate 20, the affixing position serves as a mark for fixing the face plate 1 on the cutting plate 20, and positioning of the cutting plate 20 is performed. By fitting the opening 33 to the mounting jig 30, the face plate 1 is accurately positioned and fixed in correspondence with the cutting blade 11 and the ruled line blade 12 of the die 10.
Further, when the mounting jig 30 is attached to the surface of the cutting plate 20, the guide member 40 is slidably inserted into the die mold 10, so that the die mold 10 abuts on the surface of the cutting plate 20 facing the cutting plate 20 surface. However, it enters so as to be absorbed into the die mold 10 and does not hinder the movement of the die mold 10.
In addition, the attachment jig 30 is fitted and attached to the guide member 40, and the attachment jig 30 itself is formed in a circular flat plate shape with a thickness approximately the same as the thickness of one face plate. Accordingly, when the die 10 is turned upside down and mounted, for example, on the lifting part of the elevator, and the mounting jig 30 is positioned and fixed on the upper surface of the cutting plate 20, the mounting jig 30 has its own weight or the like. Will not drop or become misaligned. Further, when fitted and integrated with the face plate 1, it is flush with the face plate 1 itself, and the sheet material P can be smoothly cut and ruled without damaging it.
The repelling member 50 interposed between the mounting jig 30 and the die mold 10 surface is aligned with the cutting plate 20 so that the mounting jig 30 is guided by the guide member 40. When affixing on the cutting plate 20, the attachment jig 30 is securely affixed on the surface of the cutting plate 20 by the adhesive means 35.
Further, the mounting jig 30 fixed to the upper surface of the cutting plate 20 matches the positioning opening 33 of the surface plate 1 with the position of the mounting jig 30, so that the surface plate 1 is placed at a predetermined position on the cutting plate 20. Since the alignment is fixed, the ruled groove 2 of the face plate 1 faces the position of the ruled line blade 12 of the die mold 10, and the outer edge portion 3 for cutting has an accurate position corresponding to the position of the cutting blade 11 of the die mold 10. Plate 1 is placed.
Since the attachment jig 30 is formed in a circular shape with a predetermined shape, for example, a plane centering on the position of the guide member 40 of the surface plate 1 attached to the guide member 40, the attachment jig 30 itself is the surface plate 1. Even when there is a relative position with respect to the guide member 40, that is, rotation with respect to the guide member 40 or the like when fitting with the positioning opening 33, the positioning with the positioning opening 33 in the face plate 1 is hindered. Does not cause.
The mounting jig 30 formed by cutting out from the surface plate 1 has good affinity with the surface plate 1 fixed to the surface of the cutting plate 20. The container material is punched smoothly by fitting and integrating the same material.

  According to the present invention, the mounting jig 30 for alignment that matches the position of the guide member 40 erected on the die 10 opposite to the cutting plate 20 is employed, and this is aligned with the surface of the cutting plate 20. The surface plate 1 can be fixed at an accurate position using the mark as a mark, and the surface plate 1 corresponding to the position of the ruled line blade 12 and the cutting blade 11 in the die mold 10 can be accurately applied to the cutting plate 20 surface. Can be attached. Moreover, for example, the ruled groove 2 and the cutting outer edge 3 in the face plate 1 may be directly attached to the die 10 without attaching the face plate 1 for forming a folded ruled line having a large weight or a large size that may be dropped or bent. Can be reliably positioned corresponding to the positions of the ruled line blade 12, the cutting blade 11 and the like of the die mold 10.

  That is, in the present invention, in aligning the die mold 10 having the cutting blade 11 and the ruled line blade 12 with the face plate 1 fixed to the cutting plate 20, the guide member protruding from the die mold 10 is provided. 40, a fitting jig 30 that matches the positioning opening 33 of the face plate 1 is fitted and fitted in the fitting hole 31, and the fitting jig 30 is aligned with the cutting plate 20 of the die mold 10 and the cutting jig 30 is attached. The ruled line blade 12 and the ruled line between the cutting edge 11 and the cutting outer edge part 3 between the die mold 10 and the face plate 1 are obtained by being attached to the 20th surface and fitting the positioning opening 33 into the mounting jig 30 so as to match. Each of the grooves 2 is matched and matched.

  Further, when the die 10 is turned upside down and placed in the lift part of the elevator and the mounting jig 30 is fixed to the upper surface of the cutting plate 20, the mounting jig 30 is inserted into the guide member 40 in the fitting hole 31. Since the mounting jig 30 itself is flat and small and lightweight, the mounting jig 30 is detached from the guide member 40 or dropped. There is no. In addition, the fitting between the guide member 40 and the mounting jig 30 may be performed by forcibly fitting the mounting jig 30 itself into the guide member 40 through the fitting hole 31, and a special adhesive may be prepared. It does not require the intervention of other members. In addition, when the mounting jig 30 is attached to the surface of the cutting plate 20, it enters so as to be absorbed into the die mold 10, and the cutting plate 20 surface of the die mold 10 does not interfere with the opposite movement to the trap. After completion, the guide member 40 can be pulled out.

  The fitting hole 31 of the mounting jig 30 can be easily formed by opening even when the mounting jig 30 is as thick as the face plate 1, for example, about 0.3 to 0.5 mm. This can be done easily and reliably by forcibly fitting the guide member 40.

  Since the mounting jig 30 is formed in a circular flat plate shape with a thickness approximately the same as the thickness of the face plate 1, the fitting of the positioning opening 33 of the face plate 1 to the mounting jig 30 is ensured. In particular, even if the mounting jig 30 itself rotates carelessly with respect to the guide member 40, the face plate 1 can always be fitted by the positioning opening 33, and at least at two locations. As a result, the face plate 1 can be surely aligned on the cutting plate 20 by fitting with the mounting jig 30, and when integrated, it becomes a continuous and smooth surface, and cuts the sheet material P. Ruled line processing and the like can be performed smoothly.

  Further, since the repelling member 50 is interposed between the mounting jig 30 and the surface of the die mold 10 when fitted to the guide member 40 of the die mold 10, the die 30 is guided by the guide member 40. When the mold 10 is aligned with the cutting plate 20 and the mounting jig 30 is affixed on the cutting plate 20, the mounting jig 30 is surely pressed onto the surface of the cutting plate 20. It can be reliably affixed by the bonding means 5 provided on the surface.

  Further, the mounting jig 30 is formed by punching in a predetermined shape from the face plate 1, and the punched portion after the punching is formed as the positioning positioning opening 33, so that the surface of the cutting plate 20 Not only has good compatibility with the surface plate 1 when fixed to the surface plate, but also the surface plate 1 and the mounting jig 30 are fitted and integrated with the same material, thereby providing smooth uniformity between them. The sheet material P obtained and punched by being interposed between the die 10 and the face plate 1 is cut and creased without damaging the sheet material P. Make it smooth. That is, after the positioning of the surface plate 1 and the mounting jig 30, the height of the upper surface is flush, and no wrinkles, irregularities or the like are generated when the sheet material P set on the surface plate 1 is punched. It also makes it possible to produce beautiful products.

  Note that the reference numerals given in the means for solving the above-described problems and the effects of the invention are given for easy reference to the parts showing the constituent parts shown in the drawings. However, the present invention is not limited to the structure / shape indicated by the reference numeral.

Similarly, it is a cross-sectional view when the mounting jig is mounted on the cutting plate by lowering the die, where (a) is before mounting and (b) is after mounting. FIG. Similarly, it is a cross-sectional view when mounting so that the opening portion of the face plate matches the mounting jig position on the cutting plate, (a) is before mounting, (b) is after mounting. Similarly, it shows the state of forming and punching a sheet material with a die mold and a face plate, (a) is a cross-sectional view before the die mold is lowered, (b) is an outer edge portion for cutting by lowering the die mold It is sectional drawing which shows the state in which the ruled line which is a crease | fold is formed.

  The best mode for carrying out the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the figure indicates, for example, the developed material material in various assemblies used as a packaging container together with the die mold 10 so as to be formed by a sheet material P such as a paper material or a plastic sheet material having a predetermined thickness. It is a surface plate used for forming folding ruled lines, cutting lines and the like to be configured. As shown in FIG. 1, the surface plate 1 has a groove-like ruled line groove 2 corresponding to the position of the crease line in the assembly on its surface. The outer edge portion 3 for cutting is a cutting line corresponding to a cutting blade 11 of the die mold 10 described later so as to follow the outer shape and the like.

  For example, when drawing the development form corresponding to the outer shape of the packaging container or the like to be assembled, the crease line, etc. by computer graphics technology, the ruled line groove 2 is a router mining process using an end mill based on the CAD data, and a groove cutting process using a laser beam. Formed by. Further, for example, an adhesive or the like for bonding and fixing to the surface of the cutting plate 20 is applied to the back surface of the face plate 1, and the adhesive surface is protected by a release paper 4 that can be peeled off.

  The face plate 1 itself is a chemical product material such as PP, PVC, or PET that has a smaller hardness difference than the sheet material P made of synthetic resin, for example, a material of a packaging container that is folded and assembled. In addition to being formed by NC processing using a plastic sheet material such as acrylic or Bakelite (registered trademark), a heavy metal plate made of stainless steel, for example, may also be used after NC processing. In addition, when it is formed by NC processing with a plastic sheet material, its thickness is, for example, about 0.3 to 0.5 mm.

  And this surface plate 1 is relative to a die mold 10 in which a cutting edge 11 having a sharp edge with a sharp tip and a ruled line blade 12 with a leading edge having, for example, a rounded folding edge, are embedded at a predetermined height. In order to do so, it is fixed to the upper surface of the cutting plate 20 using a positioning fixture 30 described later. At this time, the face plate 1 itself has a so-called loop shape arranged in the die mold 10 so that the sheet material P is punched out by the outer edge of the unfolded form by the cutting outer edge portion 3. It is arranged on the surface of the cutting plate 20 in a range that matches the vertical and horizontal total blade span interval width.

  That is, corresponding to a packaging container made of a sheet material P to be assembled, for example, a paper or plastic package, the cutting blade 11 along the outer shape of the developed form shape is embedded in a die mold 10 made of, for example, a thick plywood. Set up. Similarly, a ruled line blade 12 that forms a folded ruled line that becomes a crease line of the packaging container is also embedded in the die 10 so that the height of the ruled line blade 12 is slightly lower than the height of the cutting blade 11. The ruled line blade 12 is set and arranged corresponding to the ruled line groove 2 of the face plate 1.

  In the die 10, the cutting outer edge 3 and the ruled groove 2 in the face plate 1 are aligned with the cutting blade 11 and the ruled line blade 12, respectively. Is forcibly fitted into the mounting hole 42 opened in the die 10, and the die 10 is brought close to the cutting plate 20 and the face plate 1 without any positional displacement by the guide member 40. It is designed to go up and down.

  The guide member 40 is, for example, arranged in at least two places surrounded by the cutting blade 11 or the ruled line blade 12 of the die mold 10 and in a state where they are separated as much as possible. When the one end side of the guide member 40 is pushed in, the guide member 40 is protruded to a predetermined height. In addition, a metal pressing plate piece is arranged in combination inside the mounting hole 42 so as to have, for example, a substantially triangular shape in a plane, and the guide member 40 is forcibly fitted inside the pressing plate piece. In this way, it is positioned in a standing shape, and is arranged so as to protrude from the surface of the die mold 10.

  Then, with reference to the position of each guide member 40 pushed up into the mounting hole 42 and positioned upright, the ruled line groove 2 and the cutting outer edge of the face plate 1 are positioned at the positions of the ruled line blade 12 and the cutting blade 11 of the die 10. 3, the face plate 1 itself is formed with a positioning opening 33 that is fitted to a mounting jig 30 that is affixed to the surface of the cutting plate 20, corresponding to the number of guide members 40 and corresponding positions. Has been.

  The attachment jig 30 is formed so as to be fitted around the guide member 40, preferably around the fitting hole 31 that is preferably forcedly fitted, and to follow the opening shape of the positioning opening 33. It has a unique outer shape. Further, as shown in FIG. 2, the inner periphery of the fitting hole 31 is formed with a plurality of kerfs 32 that are formed in a cross shape, for example, in the radial direction, with respect to the guide member 40. When the fitting jig 30 is inserted through the fitting hole 31 and fitted together, the inner periphery of the fitting hole 31 is firmly held on the outer periphery of the guide member 40 so as to block the grooves 32 and attached to the guide member 40. The jig 30 is forcibly fitted and supported.

  Further, the mounting jig 30 itself has a predetermined thickness that is approximately the same as the thickness of the face plate so that the mounting jig 30 itself has a flat plate shape with a circular shape in a plane around the fitting hole 31 that fits into the guide member 40. The surface of the adhesive plate 35 is formed as a separate member from the surface plate 1, and a surface of the cutting plate 20 that contacts the surface of the cutting plate 20 is coated with a predetermined adhesive or the like or has a fine suction cup structure. A releasable release paper 34 to be protected is attached. The outer shape of the mounting jig 30 and the opening shape of the positioning opening 33 may be, for example, any one of a triangular shape, a rectangular shape, and a polygonal shape in addition to a circular shape. In order to fit the guide member 40 as will be described later, it is necessary to accurately position the direction and the like so as not to be misaligned.

  The mounting jig 30 is preferably formed of the same effect material as the face plate 1, and when the face plate 1 is fitted to the mounting jig 30 attached to the surface of the cutting plate 20 and integrated, Since the mounting jig 30 and the face plate 1 are flush with each other without a gap, cutting processing, ruled line processing, and the like by the die mold 10 are smoothly performed on the sheet member P inserted on the face plate 1.

  Further, the mounting jig 30 is partially punched out from the surface plate 1 itself in a predetermined shape so that the positioning fitting hole with the guide member 40 in the surface plate 1 is the center, so that the cut-out portion is removed. At the same time as forming the positioning opening 33 for positioning, it is also possible to use the punched-out portion that has been punched out and separated by forming the positioning opening 33 as the mounting jig 30 for positioning the face plate 1 itself.

  Further, the mounting jig 30 is made of a rubber material, a urethane resin material, a cork material, a coil spring material, or other elastic material between the die die 10 and the surface of the die die 10 when fitted to the guide member 40 of the die die 10. A repelling member 50 is interposed. The repulsion member 50 has its elastic pressing force when the die mold 10 fitted with the mounting jig 30 is close to the cutting plate 20 surface and affixes the mounting jig 30 to the cutting plate 20 surface. The mounting jig 30 is securely bonded to the surface of the cutting plate 20.

  When the face plate 1 is disposed and fixed to the upper surface of the cutting plate 20, as shown in FIG. 3, the mounting jig 30 is applied to the die mold 10 in which the cutting blade 11 and the ruled blade 12 side are directed to the upper surface. The fitting member 31 is attached in advance by fitting the tip of the attached guide member 40 with the fitting hole 31, and the release paper 34 is peeled from the attachment jig 30 to expose the surface of the bonding means 35. Then, with the die 10 turned upside down and the mounting jig 30 facing downward, the die 10 is positioned and mounted on the lifting part of a predetermined punching machine that is lifted and lowered, for example, moved downward to the cutting plate 20 surface side, and the cutting blade 11. The ruled line blade 12 is lowered to a position close to the cutting plate 20 and the attachment jig 30 attached to the tip of the guide member 40 is attached to the surface of the cutting plate 20 together with the elastic pressing force of the repulsive member 50. .

  At this time, the length of the guide member 40 is longer than the thickness of the die mold 10 by, for example, an amount corresponding to at least the thickness of the face plate 1, and as shown in FIG. When the mounting jig 30 is attached to the surface of the cutting plate 20 at a position where the guide member 40 moves down together with the ruled line blade 12 and abuts against the cutting plate 20, the guide member 40 is absorbed into the die mold 10. , And protrudes from the mounting hole 42 of the die 10 by about several millimeters. Thus, the guide member 40 may be removed from the die 10 using a drawing tool such as a pliers (not shown).

  Since the guide member 40 itself can be extracted from the die mold 10, when the mounting jig 30 is fitted to the protruding portion from the surface of the die mold 10, the guide member 40 may reach the middle position even if it is not the tip portion. It may be inserted into and fitted.

  Then, as shown in FIG. 5, after the die mold 10 is moved upward to the cutting plate 20, the release paper 4 is peeled off from the face plate 1 to expose the adhesive surface, and the mounting jig on the cutting plate 20 is fixed. The face plate 1 is fixed on the surface of the cutting plate 20 so that the positioning opening 33 of the face plate 1 is fitted and matched with the position of the tool 30. In this way, the surface plate 1 is positioned and fixed on the surface of the cutting plate 20 with the ruled groove 2 of the surface plate 1 being surely aligned with the position of the ruled line blade 12 of the die mold 10.

  As shown in FIG. 6, when the sheet material P is punched by moving the die 10 against the cutting plate 20 by a punching machine or the like (not shown), the ruled line blade 12 presses the sheet material P, and this pressing portion Is pushed into the ruled groove 2 to form a line-like folded ruled line. At this time, the die mold 10 is formed such that the height of the ruled line blade 12 is slightly lower than the height of the cutting blade 11, so that when the sheet material P is punched, the sheet material by the ruled line blade 12 into the ruled line groove 2 is formed. After the pressing of P and the cutting of the sheet material P by the cutting blade 11, the cutting blade 11 can be stopped at a position where it touches the surface of the surface plate 1.

  And, at the same time as the sheet material P is punched along the outer shape which is the outer frame of the unfolded form with the cutting blade 11 so as to be in the unfolded form as a packaging container or the like to be assembled, Folded ruled lines located within the shape are formed correspondingly by the ruled line blades 12.

  Next, an example of assembly and use of the best mode configured as described above will be described. As shown in FIG. 3 (a), first, an outer edge portion 3 for cutting along the developed outline and the like, and a ruled groove 2 along the crease line are formed corresponding to an assembly such as a predetermined packaging container. A die mold 10 in which a cutting blade 11 and a ruled line blade 12 are incorporated is prepared so as to be used together with the surface plate 1. In the die mold 10, the guide member 40 is arranged on the die mold 10, and the mounting jig 30 fitted to the guide member 40 matches the opening shape of the positioning opening 33 formed in the face plate 1. Prepare as an external shape.

  Next, as shown in FIG. 3 (b), the guide member 40 is forcibly pushed into the mounting hole 42 of the die mold 10 turned upside down so that the cutting blade 11 and the ruled line blade 12 face upward, and is arranged upright. The mounting jig 30 is fitted and attached to the guide member 40 through the fitting hole 31 to peel off the release paper 34. Then, as shown in FIG. 4A, for example, the die mold 10 is set in a punching machine with the mounting jig 30 facing downward, and then the die mold is moved to a position where the ruled line blade 12 abuts against the cutting plate 20. The attachment jig 30 attached to the guide member 40 is attached to the cutting plate 20 by the adhesive means 35 by lowering 10.

  As shown in FIG. 4B, the guide member 42 that goes out from above the die mold 10 is pulled out, and the die mold 10 is moved upward above the cutting plate 20. Then, as shown in FIGS. 5A and 5B, the positioning opening 33 of the face plate 1 is fitted and matched with the position of the mounting jig 30 on the cutting plate 20 so as to face the upper surface of the cutting plate 20. The plate 1 is fixed. At this time, since the outer shape of the mounting jig 30 matches the opening shape of the positioning opening 33, the mounting jig 30 is always positioned and fitted by the positioning opening 33 of the face plate 1, and united and integrated. There is no level difference between 30 and the surface plate 1 main body portion.

  The punching process for the sheet material P is performed in the same manner as before. As shown in FIG. 6A, for example, the die plate 10 is moved up and down in the vertical direction with respect to the cutting plate 20 disposed at the lower position. The sheet material P set on the face plate 1 is punched out. At this time, as shown in FIG. 6B, the die mold 10 pushes the sheet material P into the ruled groove 2 by the ruled line blade 12 and simultaneously cuts the sheet material P by the cutting blade 11. The die mold 10 stops at a position where 11 touches the surface of the face plate 1. In this manner, a container material in an unfolded form corresponding to an assembly such as a packaging container is obtained by punching out from the sheet member P, and at the same time, a folded ruled line that protrudes to the back part is formed as a fold in the unfolded form. The Since the container material has a groove-like folded ruled line at the fold position, a predetermined packaging container can be formed by folding along the ruled line.

  The arrangement of the die mold 10 and the cutting plate 20 is not limited to that along the vertical direction, and the same can be implemented by arranging the die mold 10 in the horizontal direction by moving along the horizontal direction.
