Description

  The present invention relates to a positioning member positioning jig used to accurately attach a surface plate to a receiving mold when punching a sheet and assembling a folding line to assemble a paper container, and a surface plate using this jig. The present invention relates to an alignment method.

  Conventionally, when manufacturing a box (paper container) such as a packaging container bent by a sheet S, a Thomson blade (punching blade) 26 of a punching die 22 is formed by punching the sheet S as shown in FIG. Are cut into a predetermined shape, and a large number of folding lines 30 are formed on the blank (punched product) S by the ruled member 25 of the punching die 22, and then bent along the folding lines 30 of the blank S. Assemble the box (paper container).

  The punching die 22 used for punching the sheet S of this kind is formed by laser machining the plywood according to the shape of the box (paper container) and the ruled lines for folding, and the Thomson blade groove and pusher of the outer shape of the box. Grooves for ruled members are formed, and a general punching die 22 is manufactured by embedding a Thomson blade 26 and a ruled member 25 having a height lower than the height of the Thomson blade 26 in each groove. In the punching process, the sheet S is inserted between the punching die 22 mounted on the upper side of the punching machine and the receiving die 21 on the lower side of the punching machine, the receiving die 21 is raised and then lowered, and punching is performed. Thus, a blank (punched product) S in which a large number of folding lines 30 are engraved in a required portion is formed by the pressing rule 25 while being cut into a predetermined shape by the Thomson blade 26 of the punching die 22. Next, it folds along the crease 30 of the blank S, and folds and assembles a box.

  However, in order to prevent more accurate engraving of the folding line 30 and cracking of the surface layer of the folding line 30 of the blank S, it is necessary to form a recess called chamfering on the receiving die 21 of the punching machine. For this reason, in recent years, an adhesive adhesive is applied to the back surface, and it can be reused by sticking or peeling off. These are also called “film-shaped surface plates” or simply “surface plates”.) Since a general punching die 22 can be used and is inexpensive, it is adhesively bonded onto the receiving die 21 of the punching machine 19. Adhesive with an agent. The CAD surface plate 15 is formed by cutting a groove into a position corresponding to the stamping member 25 of the punching die 22 from the CAD data for manufacturing the punching die 22 on the phenol resin sheet (bake sheet) 16, The portion where the blade (punching blade) 26 abuts is manufactured by cutting off the bake sheet 16 (FIG. 7).

  As a method for attaching the surface plate, as shown in Patent Documents 1 and 2, when the punching die is wood (veneer), a transfer positioning jig composed of a female member 2, a male member 6, and a transfer member 12 is used. 1 and a positioning pin is removably inserted into a punching type (male) positioning hole to transfer the transfer member 12 onto the receiving die 21, or the head of the positioning pin is mounted. The positioning disk is transferred, and a hole provided in the film surface plate or the CAD surface plate is inserted in accordance with the transfer member 12 or the positioning disk (as a mark), and the film surface plate or the CAD surface plate is received on the mold 21. Stick with adhesive adhesive.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(First embodiment)
As shown in FIGS. 1 and 2, the positioning member positioning jig 1 according to the present embodiment is provided with a punching die (male die) 22 and a receiving die (female die) 21 attached to a punching machine. When the sheet is punched and the crease is applied, the transfer member 12 is transferred to the receiving mold 21, and the jig 15 is attached to the receiving mold 21 with the transferred transfer member 12 as a mark. .

  The punching die (male die) 22 will be described using wood (veneer), which is frequently used in recent years, but it can be applied regardless of the type, whether it is made of steel, metal or resin. A through-shaped groove having a predetermined shape is formed on the surface of the wooden punching die (male die) 22, and becomes a strip-like punching blade 26 for punching the sheet S so as to be the outer shape of the paper container, and a fold of the valley fold of the paper container. The sheet-like ruled member 25 for attaching the folding line 30 to the sheet S is attached to the through groove with the cutting edges thereof aligned on the lower surface side or the upper surface side (FIG. 11). The punching blade 26 and the ruled member 25 are made of metal. The elastic member 6 is disposed so as to cover the periphery of the punching blade 26, and the elastic member 6 prevents the sheet S from being displaced (due to wrinkles) when the sheet S is punched. In order to punch the sheet S into a predetermined container shape, it is necessary to punch the sheet S including the glue margin (overlapping portion) 7.

  The receiving mold (female mold) 21 is also called a cutting plate, and will be described using wood (veneer) that is frequently used in recent years, but it can be applied regardless of the type, whether it is made of steel, metal or resin. In the case of steel or metal, the surface plate 15 is directly attached to the surface via the transfer member 12, and in the case of wood (veneer), a thin plate (flat plate) made of steel is attached to the surface. Therefore, the face plate 15 is stuck to the surface via the transfer member 12. As shown in FIG. 12, a groove in which the punching blade 26 and the ruled member 25 are in contact is formed on the surface of the face plate 15. Usually, a plurality of face plates 15 are attached to a receiving mold (female mold). At least two positioning holes 20 for alignment are formed in one surface plate 15 to maintain alignment accuracy. The surface plate 15 uses a paper phenolic material (made of a bake sheet) in order to make the adhesiveness to the metal receiving die 21 and the metal flat plate good, but is not limited thereto.

A transfer member 12 that serves as a mark of the positioning hole 20 of the face plate 15 is attached to the receiving mold (female mold) 21. As shown in FIGS. 2 and 5, the transfer member 12 is a circular flat plate having a size to be fitted in the storage groove serving as the holding means 1 b of the transfer member positioning jig 1 and has a thickness slightly protruding from the storage groove 1 b. In addition, an adhesive is applied to the lower surface, and a release paper 14 is attached to the adhesive surface 13. Here, the transfer member 12 is made of sponge or rubber. This is because adhesion to and peeling from the metal receiving mold 21 and the metal flat plate attached to the receiving mold 21 is facilitated.
The transition member 12 may be composed of a rubber magnet material (magnet). The receiving mold (female mold) 21 is a steel material (ferromagnetic metal such as iron, nickel, and alloys thereof), and it is not necessary to apply an adhesive to the lower surface of the transfer member 12, and the receiving mold (female mold). This is because the transfer on 21 is possible.

The transfer member positioning jig 1 according to the present embodiment includes a mounting means 1a that is mounted along the punching blade 26 of the punching die (male) 22 and the ruled member 25, and a holder that holds the transfer member 12 in a detachable manner. Means 1b (FIG. 2). The transfer member positioning jig 1 of the present embodiment is a rectangular thin plate, and a storage groove for storing the transfer member 12 is provided as a holding means 1b on one surface thereof, and a magnet is formed on the side surface of the rectangular thin plate. Are attached as attachment means 1a.
The magnet as the attachment means 1a is for attachment by adsorption utilizing the properties of the metal punching blade 26 and the metal ruler member 25, and is attached to two sides of a rectangular thin plate. That is, they are attached so as to be flush with one side and the other side of a rectangular right-angled corner (FIG. 1). The shape of the positioning member 1 for such a transfer member may be a triangular shape having a right angle portion or a fan shape. Therefore, the metal punching blade 26 and the ruled member 25 can be securely attached at the right angle corner θ1 and can be easily removed. The attachment means 1a may be attached between the ruler member 25 and the stamping member 25, between the ruler member 25 and the punching blade 26, and between the punching blade 26 and the punching blade 26. It may be done. For example, as shown in FIG. 9, a positioning jig 21 for a rectangular transition member as shown in FIG. 9, which is arranged between the horizontal ruled line wires 26 and 26, as shown in FIG. 10. Alternatively, it may be arranged between the longitudinal ruled line wires 26 and 26.

  The storage groove as the holding means 1b is a circular groove, and one transfer member 12 is stored in this groove (FIG. 2). Although the holding means 1b of the present embodiment has one arc-shaped groove, two or more arc-shaped grooves may be provided (FIG. 3). Since the positioning jig 1 of one transfer member 12 is provided with two or more holding means 1b, only one positioning jig 1 for one face plate 15 is attached to the punching die (male die) 21. The positioning accuracy of the face plate 15 can be maintained. When the transfer member 12 is made of a rubber magnet material, even if the receiving mold (female mold) 21 is made of steel or metal, or made of wood or synthetic resin, it is made of steel or metal. If the flat plate is attached, the transition 12 as a magnet can be adsorbed.

Next, a usage example of the positioning member positioning jig 1 according to the present embodiment will be described.
Here, a plurality of surface plates 15 are attached to a receiving mold (female mold), but since two positions are positioned with respect to one surface plate 15, two positioning holes are formed in one surface plate 15. 20 is formed, and two positioning jigs 1 corresponding to this one surface plate 15 are attached to a punching die (male die). That is, the positioning jig 1 is arranged in two places, or one positioning jig 1 having a plurality of holding means for detachably holding two transfer members 12 is arranged in two places (FIG. 1). As shown in FIG. 12, a plurality of face plates 15 may be transferred simultaneously to a metal flat plate 21 a laid on the receiving mold 21.
First, the transfer member positioning jig 1 is attached to the punching die (male die) 22. The height (width in the height direction) of the positioning member positioning jig 1 is preferably set to be the same as or slightly higher than the height of the punching blade 26 and the ruled member 25.

  Next, the transfer member 12 is fitted into the groove (holding means) 1b of the positioning jig 1, and the release paper 14 is peeled off. The positioning jig 1 with the transfer member 12 fitted in the groove (holding means) 1b of the positioning jig 1 may be attached to the punching die (male) 22 and the release paper 14 may be peeled off after attachment. . The peeled surface when peeled off or the magnet surface as a magnet should protrude from the groove (holding means) 1b and be easily transferred to the receiving mold (female mold) 21.

  Next, when the punching die 22 is attached to the punching machine 19 and the receiving die (female die) 21 is raised and then lowered, the transfer member 12 is transfer bonded to the receiving die (female die) 21 (FIG. 6 ( a)). Here, two transfer members 12 are attached to one surface plate 15, and are arranged at a plurality of locations. Then, after the receiving die (female die) 21 is pulled out from the punching machine 19, the positioning jig 1 is removed from the punching die (male die) 22. When removing the positioning jig 1, the punching blade 26 arranged at a right angle and the two corners of the ruled member 25 are in contact with magnets, and the other two sides are not attracted. Can be removed.

For the receiving mold (female mold) 21 to which the transfer member 12 has been transferred, the positioning plate 20 is inserted into the transfer member 12 on the receiving mold (female mold) 21 so that the face plate 15 is inserted. It adheres on the receiving mold (female mold) 21 with an adhesive (FIGS. 6B and 6C). Two or more positioning holes 20 are formed in the face plate 15, and the positioning holes 20 are aligned with the circular transfer member 12 on the receiving mold (female mold) 21 to prevent misalignment. Thus, it is possible to attach the surface plate 15 to the receiving mold 21 accurately.
It should be noted that two or more positioning holes 20 of the surface plate 15 are made different in size, the colors of the two or more transfer members 12 are changed, the sizes thereof are changed, or a predetermined mark is provided on the surface plate 15. By adding, it is possible depending on the implementation to make the alignment convenient.

  Next, when the transfer member 12 is removed from the receiving die (female die) 21, the face plate 15 is formed on the receiving die (female die) 21 at a position corresponding to the ruled member 25 of the punching die 22. .

  Then, the sheet S is inserted between the punching die 22 mounted on the upper side of the punching machine 19 and the receiving die (female die) 21 on which the face plate 15 is formed, and punching is performed (FIG. 11).

Here, it is preferable to use an adhesive (a microcapsule type spray or a micro sucker can be used) that can be repeatedly stuck and peeled on the back surface of the face plate 15. This is because even when the surface plate 15 is inclined, it is preferable that the surface plate 15 is not adhered to the receiving mold 21 and is adhered to the receiving mold 21 in an equilibrium state. Here, the micro sucker is a fine recessed hole (a recessed recessed hole having a diameter of 5 to 300 microns or less), and when pressed against the surface of the article, the air inside the recessed hole escapes and becomes negative pressure. The so-called sucker action is shown. In the present embodiment, when the sheet-like member having the micro sucker is attached to the back surface of the face plate 15 and pressed against the receiving mold (female mold) 21 (pressed in a parallel state), the micro sucker As a result, the air in the concave depression hole is partially removed and negative pressure is applied to absorb the adhesive. The sheet-like member having such a micro suction cup may be attached to the head of the transfer member 12. Thereby, it can be made to attach to or remove from the receiving mold 21 without using an adhesive.
In addition, since an adhesive having a predetermined thickness and whose position relative to the receiving mold 21 can be changed by changing the thickness is applied, the so-called gel-like adhesive has elasticity. Thus, the surface plate 15 can be adjusted by moving the position with respect to the receiving die 21. This adhesive may be applied to the entire back surface of the face plates 15 and 17 or may be applied to a part thereof. It should be noted that it is sufficient that this adjustment range can be moved and adjusted by about 0.1 to 0.2 mm.
