Description

  The present invention relates to a punching die for a sheet-like member and a partition body used inside a box produced using the die. More specifically, the present invention relates to a partition punching die with improved versatility and durability, and a partition body that is easy to assemble and disassemble and has a high drop-off preventing effect.

In the case of punching a sheet-like member such as paper, corrugated paper, a plastic sheet, or a liquid crystal substrate, Thomson processing that does not complicate the apparatus and can keep equipment costs low is often performed.

  In this Thomson processing, the Thomson blade is bent and incorporated into the template so that the punching shape is framed, and the blade tip of the Thomson blade is arranged in a straight line parallel to the surface of the material to be cut. The cutting material placed on the cradle is cut by pressing the entire length of the blade against the cutting material, and elastic support members are provided facing both sides of the Thomson blade (Patent Document) 1).

  On the other hand, the internal partition plate of the storage container for transportation and storage is assembled in a cross beam shape by engaging a plurality of engagement grooves formed in a rectangular partition plate. It is difficult to engage if the engagement groove is linear, and in the case of a member having a plate thickness such as a corrugated sheet such as corrugated cardboard, it is necessary to form an engagement groove having a predetermined width. Various devices have been made to prevent the dropout of the film (Patent Documents 2-5).

  Further, as a ruled line forming tool, a ruled line blade is formed in a corrugated shape (Patent Document 6), or a wrap round type packaging container that is periodically curved and symmetrically formed into two wavy cut lines for opening. A tear band may be provided, or a continuous wavy cut line having a sine curve shape may be formed in a box as a zipper for opening (Patent Document 7).

Since the engagement groove in the Thomson type for manufacturing the partition body differs depending on the plate thickness of the partition body, Thomson blades are mounted on the base in two rows in parallel with a predetermined width, and an elastic member for extrusion is disposed in the groove. It is necessary to perform a scraping operation for removing the engagement groove at the same time as punching (punching).

  However, for partitions made of corrugated cardboard or paperboard with a thickness of 3 mm or less, such as E flute and B flute, the engagement groove width needs to be a narrow groove width of about 1.6 mm to 3 mm. Mold processing is difficult, and it takes time to fine-tune the height of the left and right Thomson blades.

  Moreover, the die-cutting work could not be performed well unless a hard material such as rubber or cork was used instead of a soft sponge as an elastic member for scrap removal. At this time, the extruding elastic member is deformed, and the left and right blades are swelled outward and deformed. Then, the finished dimension of the product groove width becomes larger than the design dimension, and it becomes easy to come off when the partition plate is assembled. It will be. In addition, it is difficult and time-consuming to perform the operation of dropping the fine groove after punching.

  Further, when the blade length of the engagement groove portion in the Thomson type is increased, the cutting pressure is increased and the cutting performance is deteriorated. In order to maintain a constant cutting performance, the engagement groove formed in a predetermined area There was a limit on the number.

  On the other hand, various measures have been taken for the shape of the engagement groove to prevent the partition plate from falling off after assembly.

  The engagement groove is bent into a U-shape to facilitate engagement (Patent Document 2), or a notch groove is formed with a narrowing portion that is narrower than the thickness of the partition plate, thereby holding the partition plate (Patent Document 2). Reference 3), an engagement hole is formed in one partition plate, and a protrusion is formed in another partition plate, and these are fitted to each other (Patent Documents 4 and 5).

  However, when the shape of the engagement groove is complicated, not only is the assembly time consuming, but if the engagement strength is too strong, it is difficult to disassemble the partition after use.

  In addition, when the locking hole is provided, the punching scraps are more difficult to cut than the engaging groove, which not only increases the troublesome work process, but also leaves the punching scraps mixed in the package. Sometimes.

  Further, if the device is not devised when the partitioning body is assembled and folded in advance, the bulk becomes high, and it becomes easy to separate.

  Thomson-type cutting blades are not only linear but also corrugated, but they are used to form ruled line forming tools or cut lines (References 6 and 7). It was not used mainly for forming the engaging groove in the partition.

  Therefore, the present application provides a versatile and highly durable Thomson mold for a partition body, and can be easily assembled and disassembled, and is difficult to come off even in an assembled and opened state, and can be folded low in bulk. Was made for the purpose of providing.

  Therefore, the punching die for forming the partition body according to the present invention has a rectangular outer frame formed with a plurality of built-in portions, and the upper groove width in the built-in portion is a wide constant width regardless of the paperboard thickness. Set the two blades side by side, plant the Thomson blade so that the bottom shape of the built-in groove formed narrower than the opening becomes a tapered shape, and punch out the elastic elastic body for punching into the built-in groove Arrange.

  Furthermore, a corrugated Thomson blade is planted continuously below the built-in groove. In addition, the tip of the Thomson blade exhibiting the corrugated shape is bent and extended to the left or right, and an elastic body made of sponge or the like is disposed on both sides of the corrugated Thomson blade, and is fixed to the base. The vicinity of the engaging portion of the partition body is compressed.

  The partition body of the present application is a partition in which a plurality of mounting portions are formed at equal intervals on a rectangular outer frame, and the upper portion of the mounting groove is expanded upward and has a tapered bottom surface shape. The engaging portion having a mold shape is formed continuously in the incorporating groove.

  Even in the case of a partition having a thickness in a range that is commonly used, it is necessary to insert the sheet into the upper groove that is considerably wider than the plate thickness.

  Since the bottom of the mounting groove is formed in a tapered shape, even if the sheet insertion position is slightly deviated from the engagement groove, it is automatically guided to the engagement groove and is properly assembled.

  When the sheet is inserted by cutting with a corrugated Thomson blade, the corrugated irregularities of the corrugated corrugation are easily bent and bent to the left and right, and once assembled, the irregularities mesh with each other and do not fall off even if the top and bottom are reversed. Accordingly, there is no scattering during the moving operation after the partition plate is assembled. On the other hand, when removing the partition plate, it can be pulled out with a light force and can be easily disassembled.

  Conventionally, since the engaging groove of the partition body formed by two parallel straight blades becomes a notch engaging portion formed by one corrugated blade, the groove portion of the assembled partition is reduced, and the punching die The total length of the blades used in is shortened. As a result, the cutting pressure at the time of the punching operation can be reduced, and it is possible not only to increase the engaging groove portion in the same area as compared with the conventional case, but also to improve the durability of the Thomson type.

  Since a narrow engagement groove and a locking hole are not formed, there is no need for a dropping operation, the partition manufacturing process is facilitated, and no leftover waste is mixed into the box.

  By extending the notch engaging part to the left and right, such as L-shaped or T-shaped, it assists the bending of the cut groove when installing the partition body, further increasing the ease of installation, and also has the effect of preventing the partition groove from breaking. Yes. In addition, the Thomson blade can be prevented from falling out of the punching die and the deformation can be prevented.

  In addition, when the extended cut-out part folds the assembled partition, it forms a relief of the sheet thickness, reducing the repulsion when folding, reducing the volume of the partition, and transporting and storing the pre-assembled partition Convenient to.

  Since several types of sheets with different types of engagement grooves are included, partition plates with various thicknesses can be manufactured using the same Thomson mold, and versatility is enhanced.

  The size inside the partition after assembly can be changed depending on the thickness of the sheet, and the optimal partition can be formed using a single Thomson mold even for items with slightly different dimensions, such as preserved food bottles. It is.

  Since the grooving Thomson blade is a single blade, there is no need for a fine adjustment operation for making the height difference between the two blades arranged in parallel for forming a conventional narrow groove the same.

  Since a hard support material such as rubber or cork used in the operation for removing sludge from the narrow groove is not used, the punching operation is facilitated, and the cutting pressure applied to the Thomson mold is reduced, thereby improving the durability of the mold.

  Hereinafter, the best embodiment of the present application will be described in detail with reference to the drawings.

  FIG. 1 shows a Thomson type according to the present application. The Thomson mold 1 is used when a partition body is formed by cutting a sheet material made of corrugated paper, cardboard, or a synthetic resin material into a required shape, and a flat substrate 2 made of resin or wood plywood and the like. A body part is press-fitted into a groove provided on the substrate 2, a Thomson blade 3 having a blade tip projecting is implanted, and a support member 4 having elasticity is provided at appropriate intervals on both sides of the Thomson blade. In addition, an extrusion member 5 for scrap removal is disposed between the built-in grooves.

The support member 4 and the extrusion member 5 are formed of a high-density elastic body such as rubber or urethane elastomer.
The Thomson blade 3 includes a horizontally long rectangular outer frame 7 and a plurality of built-in portions 6 provided at equal intervals.

  FIG. 2 is an enlarged view of the built-in portion 6.

  The built-in portion 6 is planted in parallel with two Thomson blades 9-9 so as to form a groove that continues from the opening 8 that is widened toward the upper side of the outer frame 7, and the lower end 9a-9a is the center. A groove having a taper-shaped bottom portion is formed by inclining toward the bottom.

  Further, an extruded sponge 5 is disposed between the Thomson blades 9-9, and an adhesive layer provided on the bottom surface of the sponge is attached to the base 2 and fixed.

  Since the engagement portion forming Thomson blade 10 is cut out from the center of the bottom of the groove toward the lower side, and the end portion 11 of the Thomson blade is bent and extended to the right at a substantially right angle. is there.

  In this embodiment, the engaging portion forming Thomson blade 10 has a sine curve wave shape, but is not limited thereto, and may be a triangular wave or a trapezoidal wave. Any shape can be used as long as it is continuous. The height of the unevenness decreases as the plate thickness of the partition becomes thinner.

  Further, the bending direction and shape of the end portion are not limited to those of the present embodiment, and may be formed in an inverted T shape or an inverted Y shape by extending left and right.

  In order to fix the Thomson blade or to prevent the partition groove from being broken, it is generally practiced to bend and plant the end, but in this case, no cut is formed in the material to be cut. Thus, the device which does not press-contact a sheet | seat by making the blade height of a bending part low is made | formed. On the other hand, the purpose of this application is to form a cut following the corrugated engagement portion, so the height of the bent Thomson blade is the same as the height of the straight portion.

  Support members 4-4 are disposed on both sides of the Thomson blade 10 forming the engaging portion. In addition to supporting the Thomson blade 10 to properly cut out the engaging portion, there is also an effect of pressing and compressing the vicinity of the engaging portion of the material to be cut. As a result, the sheet having a thickness of corrugated cardboard or the like is crushed in the vicinity of the assembling portion and is easily assembled.

Next, the partition body manufactured using the Thomson mold of the present application will be described.
The partition body is formed to have a desired width and height, and a plurality of vertical partition bodies and horizontal partition bodies are crossed at right angles with the top and bottom inverted, assembled into a cross-girder shape, and stored in a packaging box. The

  FIG. 3 is a front view of the partition 12 according to the present invention.

  The partition body 12 is a rectangular plate manufactured by punching a sheet-shaped workpiece, and includes a plurality of built-in portions 13 for fitting other partition bodies so as to extend downward from the upper long side, It is formed at equal intervals.

  According to FIG. 4 in which the built-in portion 13 is enlarged, the built-in portion 13 is formed as an opening 15 having the upper end of the built-in groove 14 widened upward, and the groove width is formed as wide as about 8 mm regardless of the thickness of the partition. A built-in groove 14 is formed downward from the opening. Further, the bottom surface of the built-in groove 14 is formed in a V shape.

Since the opening 15 is formed with a certain wide width, the sheet can be inserted smoothly during assembly, and even if the partition inserted in the assembly groove 14 is slightly displaced from the engagement position, It is guided to the engaging portion at the proper position by the bottom surface shape.
The shape of the bottom surface portion of the built-in groove 14 is a tapered shape or the like, and may be any shape as long as it has a function of guiding the built-in partition body to the engaging portion. For example, it can be formed in a semicircular shape.

  The engaging portion formed continuously at the lower center of the built-in groove 14 is an engaging portion 16 made of a corrugated Thomson blade, and has a curved shape that meanders continuously in a substantially sine curve shape in plan view. It is a cutting line. The distal end portion 17 of the engaging portion 16 is further extended in the right direction, and is an engaging portion having a substantially L-shaped corrugated shape as a whole.

  By bending and extending the tip of the engagement cut at a substantially right angle, not only the breakage of the cut is prevented, but the bending of the partition during assembly is supplementarily increased, so that the partition can be assembled smoothly. In addition, when folded after the partition body is assembled, the lateral cut portion 17 is deformed and opened, so that the folding operation is not hindered and the bulk is reduced even in the folded state, and the partition body is assembled and transported and stored in advance. Convenient for.

  The cut shape at the tip of the engaging portion is not limited to the present embodiment, and any shape having an effect of escaping at the time of incorporation or folding may be used. For example, it is possible to extend not only on one side but also on both the left and right sides to form an inverted T-shaped cut or an inverted Y-shaped cut as a whole (see FIG. 5).

  Further, the corrugated cut may be formed without necessarily bending and extending the tip. This is because the corrugated continuous shape along the sine curve can be expected to have an effect of preventing breakage without forming a stopper.

  FIG. 6 shows the assembled state of the partitioning bodies. From the upper side of a plurality of the partitioning bodies arranged in parallel, another partitioning body with the top and bottom inverted is inserted so that the wide opening portions of the assembling portion are engaged with each other. And then assemble it.

  At this time, the partition body of the present application has a constant wide (about 8 mm) opening regardless of the thickness of the partition body to be incorporated, so that the partition body can be easily inserted. Accordingly, the partition body can be smoothly pushed into the interior, and the assembled partition body is guided to the engaging portion along the bottom surface of the built-in groove formed to be tapered.

  The engaging portion at the time of assembling the partition body of the present application is not formed in a groove shape, but is a corrugated cut formed by a single blade formed continuously in the incorporating groove.

  That is, even if the partition is 3 mm or less, it is not necessary to form the built-in groove narrowly in accordance with the thin plate thickness. Therefore, the demerit caused by the thin built-in groove in the partition body manufacturing process of 3 mm or less does not occur in the Thomson type and partition body of the present application.

  Thereafter, the engaging portions having the corrugated shape proceed over the convex portions, and after the engagement is completed, the corrugated irregularities are entangled and locked, so that the partition body does not come off after assembly. On the other hand, when disassembling the partition after transporting the stored items, disassembly is easy without requiring a large force.

  FIG. 7 shows an application of the engaging portion provided in the partition body of the present application to the engaging means of the packaging box. In the packaging box, a general method is to insert a convex portion provided on the lid portion into the cut portion of the main body as a means for locking the lid after opening. However, this method has a low locking function, and the engagement is released by a light impact, resulting in inconvenience.

  Further, if the cardboard is sealed with an adhesive tape or the like like the opening of the cardboard, the cardboard is damaged when the cardboard is peeled off together with the adhesive tape.

  Therefore, a pair of V-shaped cuts 20 are formed in the substantially central portion of the upper edge 19a of the main body 19 of the packaging box 18, and the cuts 21 by the corrugated Thomson blade are continuously formed so that the cut ends 21a face each other. Bending and extending. On the other hand, a pair of V-shaped cuts 23 are also formed at corresponding portions of the flap 22 of the lid to continuously form the corrugated cuts 24, and the cut ends 24a-24a are bent and extended in the opposite direction.

  When the flap 22 of the packaging box 18 is engaged with the main body 19, the corrugated notches 21 and 24 are firmly locked.

  The present invention is used as a die for sheet-like members and can be manufactured not only for flat plate die cutters but also for rotary die cutters. Further, the partition body can be used as a partition for a container for transportation and storage.
