Description

  The present invention has, for example, a cutting blade and a ruled line blade installed above a cutting plate in a punching machine when forming a container material for assembling and constituting a packaging container for packaging and storing various articles. It is related to the die plate that cuts and separates the outer shape of the packaging container from the specified sheet material together with the die, and at the same time forms the crease line, without using any adhesive when fixed on the cutting plate. The present invention relates to a surface plate for die cutting that can be accurately positioned and fixed on a cutting plate in correspondence with die-type cutting blades and ruled line blades, and that can be reused repeatedly.

  Conventionally, for example, a punching machine such as Orton for performing punching processing when a container material of a packaging container is cut out from various sheet materials such as paperboard, corrugated cardboard, plastic, etc. and at the same time forming a bent part and a cut-and-separated part. In this case, a surface plate provided with a ruled line groove for so-called face carving for forming a bent portion in the container material and a cutting outer edge portion for cutting and cutting the sheet material is used, for example, an iron plate or a stainless steel plate. The sheet material is affixed on a cutting plate made of wood, etc., and the container material is cut out from the sheet material by striking the sheet material with a die plate made of wood board having a cutting blade and a ruled line blade opposite to each other. And a cutting separation part.

  As the above-mentioned surface plate for forming the bent portion and the cut and separated portion, for example, a so-called CAD surface plate formed by NC processing a plate made of heavy stainless steel plate in addition to a resin plate such as bakelite and PP Is attached to a cutting plate of a punching machine such as an auton, and a die-shaped ruled blade is inserted into the groove, and the periphery is cut out by a cutting blade.

  Further, the groove for forming ruled lines on the surface of the stencil surface, for example, when drawing the container material of a packaging container to be assembled as a developed form corresponding to the outer shape provided with the folding line, etc. by computer graphics technology, Originally formed by router mining by end mill and grooving by laser beam. Further, for example, an adhesive or the like for bonding and fixing to the cutting plate surface is applied to the back surface of the face plate, and the adhesive surface is protected by a release paper that can be peeled off.

  When fixing such a surface plate to the cutting plate surface, the release paper is peeled off, and then the adhesive surface applied to the back surface of the surface plate is brought into contact with the cutting plate and fixed. However, every time this face plate is used, it is fixed on the cutting plate and discarded after use. For example, it is reused by reapplying adhesive. Alternatively, a CAD surface plate that can be used repeatedly as disclosed in Patent Document 1 has been proposed.

  That is, the CAD surface plate shown in Patent Document 1 applies a reuse paste that can be pasted, peeled off, and re-applied on the back side, and the reuse glue surface can be peeled away so that dust or paper dust does not adhere to it. Protected with paper pattern. Then, when the CAD surface plate is fixed on the cutting plate, it is appropriately performed by attaching it to a set pin attached to a die, and the release surface of the CAD surface plate is removed, and the punching machine has a thick and hard cutting plate. It is supposed to be bonded to the top with a reuse glue surface. In addition, it is assumed that after use, it is peeled off from a thick and hard cutting plate in a punching machine, and the reuse paste surface is protected with a release paper for temporary storage.

Utility Model Registration No. 3137395

  However, the CAD surface plate shown in Patent Document 1 is fixed on the cutting plate, and when it is reused after peeling off the CAD surface plate after use, dust or moisture adheres to the surface of the adhesive material or is stored. The adhesive material itself deteriorates or the like, and the fixing force is reduced, and the adhesive material is easily damaged. Therefore, even if it can be reused, if it is used several times, the CAD surface plate must be discarded, and another new CAD surface plate needs to be manufactured and used after that. In addition, there is a risk of emitting toxic pollutants at the time of disposal, which has a problem in that it has an adverse effect on the environment.

  Therefore, the present invention was created in view of various circumstances that existed in the past, and once peeled off, the sticking force can be restored by cleaning even if it gets dirty with dust or moisture on the sticking surface side, An object of the present invention is to provide a die-cutting surface plate that can be stored for a long period of time, can be reused any number of times without weakening the sticking force, and has strength enough to withstand repeated use.

In order to solve the above-described problems, the present invention is a die-cutting surface plate that is fixedly arranged on a cutting plate 20 of a punching machine so that cutting lines and crease ruled lines are formed on the sheet material P. The non-adhesive adsorption layer 5 that can be attached to, peeled from, and reattached to the surface of the cutting plate 20 is formed on the attachment surface side of the surface plate 1.
Moreover, the non-adhesive adsorption layer 5 can be formed by an acrylic resin layer having a thickness of 50 to 150 microns having a micro sucker structure having innumerable fine depressions 6.
In the surface plate 1 itself, an opening 7 for positioning the surface plate 1 is formed in the surface plate 1 so as to match the position of the mounting jig 8 for positioning the surface plate 1 fixedly attached to the surface of the cutting plate 20. be able to.

In the surface plate for die cutting according to the present invention configured as described above, the non-adhesive adsorption layer 5 formed on the surface of the surface plate 1 on which the adhesive plate 5 is formed has innumerable fine recessed holes 6 formed on the surface thereof. When the sticking surface is pressure-bonded to the cutting plate 20, the non-adhesive adsorbing layer 5 is slightly crushed and the numerous fine recessed holes 6 are in a vacuum state in a negative pressure state. Causing pressure-sensitive adsorption force.
The pressure-sensitive adsorption force in the negative pressure state of the countless fine recessed holes 6 causes the face plate 1 itself to be securely fixed and held on the cutting plate 20, and does not cause a positional shift even by repeated press pressure by the die die 10.

  According to the present invention, even if the sticking surface side of the punching machine is once peeled off after being used for fixing, even if the sticking surface side becomes dirty with dust or moisture, the sticking force can be restored by cleaning. The adhesive can be reused any number of times without weakening, and can be stored for a long time, and the non-adhesive adsorption layer 5 increases the strength of the surface plate 1 itself, so that it can withstand repeated use. Obtainable.

  That is, this is because the present invention has formed the non-adhesive adsorption layer 5 that can be attached to, peeled off from, and reattached to the cutting plate 20 on the attachment surface side of the face plate 1. Thus, even if an adhesive such as glue is not applied to the sticking surface, it can be fixed and peeled off any number of times simply by pressure bonding.

  Further, since the non-adhesive adsorption layer 5 is formed by an acrylic resin layer having a thickness of 50 to 150 microns having a micro sucker structure having innumerable fine recessed holes 6, the non-adhesive adsorption layer 5 is also resistant to lateral displacement and is stamped. The pressing plate 1 does not cause the face plate 1 to shift in any direction.

  Further, the non-adhesive adsorbing layer 5 itself can be reused because the adsorbing force is recovered by wiping it lightly even if it is soiled with dust. When the non-adhesive adsorbing layer 5 itself is not damaged during reuse, the non-adhesive layer 5 is non-adhesive, so that the sticking force is not weakened, and this enables repeated use over a long period.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 shown in the drawing is formed by, for example, CAD used for forming a folding ruled line simultaneously with cut-and-cut in a punching machine. It is the surface version that was made. As shown in FIG. 1, the surface plate 1 itself is provided with a groove-like ruled line groove 2 corresponding to the position of the crease line in the packaging container, for example. The outer edge is a cutting outer edge part 3 corresponding to the arrangement form of the cutting blade 11 in the die mold 10 to be described later for cutting out a necessary outer shape portion of the packaging material developed from the sheet material P.

  The face plate 1 itself is a material in which the hardness difference from the sheet material P is made smaller than that of a sheet material P such as paperboard, corrugated paper, and plastic sheet, which is a container material of a packaging container to be folded and assembled. In addition to plastic sheet materials such as PVC, PET, acrylic, Bakelite (registered trademark), and glass fiber materials, a plate made of heavy stainless steel plate or the like may be NC processed.

  Further, as shown in FIGS. 2 and 3, a non-adhesive adsorption layer 5 for adhering and fixing to the surface of the cutting plate 20 is formed on the back surface, which is the attachment surface of the face plate 1, and the surface thereof Is protected by a protective sheet 4 made of, for example, a transparent synthetic resin film having a predetermined thickness. This non-adhesive adsorbing layer 5 is formed by applying an acrylate copolymer emulsion liquid containing countless fine bubbles having a diameter of 5 to 40 microns to the sticking surface side of the face plate 1 and drying it. The surface is formed by an acrylic resin layer having a thickness of about 50 to 150 microns, and the surface thereof has a micro sucker structure having countless fine recessed holes 6.

  Specific methods for forming the non-adhesive adsorption layer 5 include, for example, an acrylic copolymer resin DICNAL MEP-20WO 100KG, a foam stabilizer DICNAL, M-40 10KG, a thickener DICNAL MX 10KG, and a melamine resin as a crosslinking agent. An acrylic emulsion made by mixing 5KG (both from Dainippon Ink and Chemicals Co., Ltd.) is mixed with air through a mechanical foaming machine, Oaks mixer, and dispensed. A foamed fine foamed acrylic emulsion liquid containing bubbles is generated, and this is uniformly applied to an arbitrary thickness on the back surface of the surface plate 1 polished to a smooth surface. Formed by forming an acrylic resin layer with a thickness of 50 to 150 microns by drying for 7 minutes in a drying oven at 110 to 140 ° C. That.

  On the other hand, as shown in FIG. 4C, a cutting blade along the outer shape of the developed form corresponding to a packaging container made of a sheet material P such as paperboard, corrugated paper, or plastic sheet to be assembled as shown in FIG. 11 is embedded in a die 10 made of thick plywood, for example. Similarly, a ruled line blade 12 that forms a folded ruled line that becomes a crease line of a container material that becomes a packaging container is also embedded in the die mold 10, and the height of the ruled line blade 12 is set to the height of the cutting blade 11. Set slightly lower. At this time, the ruled line blades 12 are arranged corresponding to the ruled line grooves 2 of the face plate 1.

  Reference numeral 7 in the figure denotes a surface plate positioning opening formed by punching the positioning mounting jig 8 so that the surface plate 1 has a flat disk shape. That is, when the face plate 1 is positioned and fixed to the surface of the cutting plate 20, the die plate 10 surface is aligned with the cutting edge 11 and the ruled line groove 2 corresponding to each of the ruled line blades 12 and the outer edge 3 for cutting. The surface plate 1 itself is aligned and temporarily fixed, and in this state, the die mold 10 is moved downward, for example, to transfer the surface plate 1 onto the cutting plate 20. At the time of this transfer, only the mounting jig 8 is fixedly attached on the cutting plate 20, the surface plate 1 is removed by the upward movement of the die mold 10, and then the surface plate 1 itself with the surface of the non-adhesive adsorption layer 5 exposed. The face plate 1 is fixed onto the cutting plate 20 so that the opening 7 of the face plate 1 is aligned with the position of the mounting jig 8 attached on the cutting plate 20. By doing so, the outer edge portion 3 for cutting is surely aligned with the position of the cutting blade 11 of the die mold 10 and the ruled line groove 2 is aligned with the position of the ruled line blade 12, respectively. Are assumed to be accurately positioned and fixed. Of course, the opening 7 and the mounting jig 8 themselves are formed as necessary, and the formation and use thereof are optional.

  Next, an example of use of the configuration configured as described above will be described. When the face plate 1 is fixedly installed on the upper surface of the cutting plate 20, as shown in FIGS. 4 (a) and 4 (b), While the die mold 10 is moved upwardly above the cutting plate 20, the protective sheet 4 is peeled off from the back surface of the face plate 1 to expose the surface of the non-adhesive adsorption layer 5 and is mounted on the cutting plate 20. For example, using the mounting jig 8, the surface plate 1 is fixed on the cutting plate 20 so that the opening 7 of the surface plate 1 matches the position. The mounting jig 8 is formed as a flat disk so as to form a flat surface that is flush with the surface of the surface plate, and is left as it is. When punching the sheet material P, the sheet material P is moved together with the surface plate 1 from below. It supports (see FIG. 4 (c)).

  At this time, as shown in FIG. 3A, the non-adhesive adsorption layer 5 formed on the attachment surface side of the face plate 1 has a micro sucker structure in which countless fine recessed holes 6 are formed on the surface. Therefore, when the sticking surface is pressure-bonded to the cutting plate 20, the non-adhesive adsorbing layer 5 is slightly crushed as shown in FIG. The pressure is brought to a vacuum state, and the suction force of the negative pressure air causes a pressure-sensitive adsorption force.

  The punching process for the sheet material P is performed in the same manner as before, and as shown in FIG. 4C, for example, the cutting plate 20 is moved by an upper die die 10 that moves up and down with respect to the cutting plate 20 disposed at the lower position. The sheet material P set on the surface plate 1 on 20 is punched out. At this time, the die mold 10 causes the sheet material P to be pushed into the ruled groove 2 by the ruled line blade 12 lower than the cutting blade 11, and simultaneously cuts and cuts the periphery of the sheet material P by the cutting blade 11.

  In this way, a container material in an unfolded form corresponding to the packaging container is obtained from the sheet material P, and at the same time, a folded ruled line projecting to the back part is formed as a fold in the unfolded form. Since the container material has a groove-like folded ruled line at the fold position, a predetermined packaging container is configured by folding along the ruled line.
