Description

[Detailed description of the invention]

[Field of Industrial Application] The present invention is useful for punching blanks, which are board materials for folding carton assemblies, from original sheets in paper carton punching work, or at the same time, for stamping paper products made of paperboard, corrugated cardboard, etc. The present invention relates to a groove forming material for pressing a line, which can reliably and easily create grooves that match the ruled lines on the surface of the lower mold board when printing. [0002]

[Conventional technology]

Among processed paper products, blanks, which are board materials for assembling paper containers, are cut to predetermined shapes and dimensions or cuts with a cutting blade of a punching die, and the creases are cut with a creasing blade as folding or folding parts. A ruled line is created, and smooth folding or folding is performed along the ruled line. In order to stamp accurate and useful ruled lines on the blank, grooves with a width determined by the thickness of the scoring blade and the material thickness of the blank are provided at important points on the lower mold plate corresponding to the blank. The required lines are stamped on the blank using the grooves and a creasing blade driven into the groove at an appropriate depth.Nowadays, a groove corresponding to the creasing blade is placed on the lower die board surface. Instead of making any engravings, glue a thin piece of cardboard or the like in two parallel ridges on the surface of the lower mold board, and use the gap between these two ridges as a substantial groove. Means for doing so have been widely adopted, and various methods have been disclosed for their use. [0003] The present inventor first created creasing grooves on the surface of a base sheet, fixed a ribbon-like adhesive substrate on the grooves, bonded to the creasing blade, and then hitting the lower mold board surface to form the creasing blade. Application No. 57-13122 for a marking groove tape device that makes it possible to form marking grooves on the lower mold board surface that accurately align with the marking grooves.
It was proposed as No. 5 (Utility Model Application No. 59-35025). With this invention, it is possible to extremely easily provide a creasing groove directly under the creasing blade, and productivity is also improved.The force plate groove tape and the creasing blade are connected via a ribbon-shaped adhesive substrate. Therefore, it is sometimes difficult to maintain an accurate right angle between the two sides, and local monitoring is required to ensure that the adhesive layer of the groove tape contacts the lower mold board surface simultaneously on the left and right sides, and at the same time, pressure with the scorching blade is required. It was difficult to reach the edge area of the groove tape. [0004]

[Purpose of the invention]

In view of the current situation, the present invention has been developed to provide grooves of a width adapted to the thickness of the blank sheet material when forming grooves on the lower die plate surface necessary for creating ruled lines on blanks etc. using a creasing blade attached to the upper die. This was done to propose a means for accurately forming grooves on the lower mold board surface while aligning them with the pressing line of a predetermined scribing blade. As long as the tip surface area of the creasing blade and its adjacent area are fixed in the set groove on the upper surface of the installation auxiliary strip, which also serves as a ruler, and the creasing blade is struck against the lower die board surface, the groove forming member can be set as desired. A groove-forming material for score pressing that is adhered to the board surface and configured such that as the score-pressing blade rises after hitting, the groove-forming member separates from the score-pressing blade and is fixed at a predetermined position on the lower mold board surface. The purpose is to provide [0005]

[Configuration and embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings. As shown in FIG. 1 or FIG. The base sheet 6 is adhered to create the creasing grooves 5, and then the base sheet 6
A pressure-sensitive adhesive layer 11 covered with a release paper 9 for protection when not in use is provided on the back side of the holder. Further, a gutter-shaped installation auxiliary strip 7 having a flange edge that hangs over the groove forming members 4, 4 is inserted into the line pressing groove 5, and this installation auxiliary strip 7 is inserted.
A joining tape 8 is pasted from both edges of the groove forming member 4 to each of the groove forming members 4, and the attachment auxiliary strip 7 is fixed in a regulated state in the marking groove 5. 6 to 8 are diagrams showing the external appearance in appropriate lengths; FIG. 6 shows a plan view, FIG. 7 shows a side view, and FIG. 8 shows a bottom view. [0006] The attachment auxiliary strip 7 is such that the flange edges protruding on both sides come into contact with the upper surfaces of the groove forming members 4 4 on both sides, and along the center line of the gutter-like portion, the applied scoring blade 3 The set groove 12 has a width equal to the thickness of the set groove 12, and the bottom surface of the mounting auxiliary strip 7 has a gouge (commonly known as a hollow) with a width approximately equal to the set groove 12, as shown in FIGS. 1 to 5. ,
This contributes to flexibility when inserting the attachment auxiliary strip 7 into the creasing groove 5 and elasticity that provides fixation during insertion, and the material thereof is preferably made of fiber or the like. [0007] In this way, the groove forming members 4, 4 parallel to each other are fixed to the surface of the base sheet 6 having the pressure sensitive adhesive layer 11 on the back side, and the line pressing grooves 5 created by these groove forming members 4 are formed. The marking groove forming material 10 of the present invention is added with an attachment auxiliary strip 7 that is inserted into the groove and fixed with the aid of the joining tapes 8, 8.
is formed. [0008] The material of each groove forming member 4, 4 is preferably a hard fiber press-finished laminated paper or a resin-treated paper, and the base sheet 6 can be made of a strong synthetic resin sheet. When the base sheet 6 is made of such a material, it can be used without tearing or turning over even if the creasing blade 3 stamps the blank sheet material several thousand times or more. Endure. A metal sheet can be used instead of the synthetic resin sheet for the base sheet 6, and an appropriate thickness can be selected within a range that does not require compensation for the counterpoint relationship between the tip of the creasing blade 3 and the lower mold board surface. is the same as for synthetic resin. Furthermore, installation auxiliary strip 7
When a highly elastic material such as a rubber material is used, the joining tape 8 can be omitted. [0009]

[Actions and effects of the invention]

When actually using the scoring groove forming material 10 of the present invention,
As shown in FIG.
Then, the tip of the creasing blade 3 attached to the upper mold 1 is inserted. At this time, due to the material of the attachment auxiliary strip 7, the elastic cross-sectional shape, and the setting of the set groove 12, the creasing blade 3 is tightly fitted over the entire length of the set groove 12, and is further fitted into the cella I/groove 12. The frictional force is increased with the aid of the partially wrapped joining tape 8, and the groove forming material 10 for score pressing is held firmly in a state where its center line and the cutting edge line of the score pushing blade 3 are aligned. ing. [0010] Once the line pressing groove forming material 10 is set on the line pressing blade 3, the release paper 9 on the back side of the base sheet 6 is removed, leaving the adhesive layer 11 exposed as shown in FIG. Creasing blade 3
When the upper die 1 equipped with the upper die 1 is struck toward the lower die plate surface 2, the scoring groove forming material 10 is fixed at a required position on the lower die plate surface 2. In this state, the base sheet 6 is firmly fixed to the lower mold board surface due to the pressure-sensitive adhesive function of the adhesive layer 11.
Then, when the upper die is operated to raise the score pushing blade 3, the attachment auxiliary strip 7 is separated from the score pushing blade 3 and remains inserted into the score pushing groove 5. Next, as shown in FIG. 4, the groove forming member 4 is removed from either end by peeling off the bonding tape 8 that stabilizes the attachment auxiliary strip 7, or at the same time lifting and removing it together with the attachment auxiliary strip 7. ．．
4 are installed parallel to each other in a line-symmetrical manner, and scoring grooves 5 are formed on the lower mold board surface 2. [0011] Note that the creasing groove forming material 10 of the present invention may also be provided with narrow grooves 13 parallel to and close to the creasing grooves 5, as shown in FIG. In this example, the part near the side edge is cut off using the narrow groove 13 or the attachment auxiliary strip 7 as a ruler, and the groove forming material 10 for marking press and the wall of the narrow groove 13, which are also cut off by the narrow groove 13, are connected to each other. If they are placed in parallel on the lower mold board surface 2 so that they face each other, it is very convenient to form two ruled lines (frames). Furthermore, when the groove forming material for scoring of the present invention is set on the scoring blade, it can be fixed to the belly plate surface of the scoring blade while maintaining the correct right angle.
At the moment of hitting the lower mold board surface, the entire surface of the base sheet uniformly contacts the surface, and the scoring grooves 5 are precisely formed at the desired positions without any twisting or line misalignment caused by slanted contact. can do. [0012]Furthermore, the scoring groove forming material of the present invention has a characteristic that it can easily handle all conditions of paper carton processing, compared to conventional devices of this type. In other words, the conventional groove forming material for marking is made of synthetic resin, and a large number of resin molding molds must be prepared in accordance with the specifications of the groove forming tape or the attached set tool. However, in the groove forming material for marking of the present invention, an increase in cost and time cannot be avoided.
Since the groove forming member for forming the scoring grooves and the attachment auxiliary strip are made of fiber, they can be produced by cutting. The paper cartons currently in use come in a wide variety of sizes, including those that are bulky, heavy, and fold up at the same time. Alternatively, the present invention, which has a structure that can be manufactured only by cutting without the need for an injection machine, can be economically and rapidly produced even in small quantities of many items, and has great industrial applicability.
