Description

  The present invention relates to a pin separation template used in a pinboard type scrap removing device and a method of manufacturing the same.

  A box-shaped part used for packaging an article is manufactured from a sheet of paper or plastic. In this processing sheet, a score line is provided in advance at the boundary between the product part forming the box-shaped part and the other residue part. Conventionally, in order to improve the efficiency of manufacturing box-shaped parts, there is a pinboard type scraper that can be separated into a product part and a waste part at once after collecting a large number of processing sheets. It's being used. In such a pinboard type scrap removing device, a pin separation template for defining a pin arrangement pattern is used.

  For example, in Japanese Patent Application Laid-Open No. 2001-121484 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2002-103288 (Patent Document 2), a waste portion is formed from a large number of upper mold pins provided on an upper mold by a template for an upper mold pin. A configuration is disclosed in which a pin for pressing is selected, and a product part supporting pin is selected from a number of lower mold pins provided in the lower mold by a template for the lower mold pin. Each of these templates is formed by sandwiching a template body (pattern paper) cut in accordance with the shape of the product portion between a pair of pin boards provided with a large number of holes in a matrix.

  Further, in Japanese Patent Application Laid-Open No. 11-5262 (Patent Document 3), after removing interference pins straddling the product portion and the residue portion, a large number of pins held on the upper substrate by one template are There is disclosed a configuration in which an object to be left on a substrate and an object to be dropped on a lower substrate are distributed. This template is formed by affixing a paperboard that leaves only a dregs part to a thin plastic plate provided with a large number of holes in a matrix.

JP 2001-121484 A (Patent No. 3256690) JP 2002-103288 A (Patent No. 3497123) JP 11-5262 A (Patent No. 333797)

  As described above, in the pin separation template used in the conventional pinboard type scraping device, a pattern without a hole having a shape corresponding to a product is physically pasted on a plate (board) having holes in a matrix shape. Thus, the insertion hole of the pin to be moved together with the pin separation template (that is, the pin not moved relative to the pin separation template) is blocked. Therefore, when punching out box products of various sizes and shapes with a single scraping device, that is, when performing multi-product and small-quantity production, it is necessary to manually attach a pattern to each product. In such a case, since it takes time to manufacture and replace the pin separation template, there is a problem that productivity is lowered. Therefore, there has been a demand for a pin separation template having a simple structure that can reduce or reduce the effort for template creation.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a pin separation template having a simple structure and a manufacturing method thereof.

This pin separation template is a single sheet-shaped plate having a product part region corresponding to the product part and a residue part area corresponding to the residue part, and a hole for allowing a pin to pass only through the residue part area. A portion is formed.

  Preferably, the hole is composed of a plurality of individual holes through which the pins are individually passed.

  The hole portion may have an integrated hole through which a plurality of pins are passed.

  A method for manufacturing a pin separation template according to another aspect of the present invention is used in a pin board type scrap removing device, and pins for determining a pin arrangement pattern when separating a processing sheet into a product portion and a residue portion It is a manufacturing method of a separation template. In this manufacturing method, a single sheet-shaped plate having no holes is prepared, and a product portion region corresponding to the product portion and a waste portion region corresponding to the waste portion are specified from the entire region of the plate. And a step of forming a hole through which the pin passes only in the debris region of the entire region of the plate.

  A method of manufacturing a pin separation template according to still another aspect of the present invention is a method of manufacturing a pin separation template for separating a part of pins from a plurality of pins arranged in the same row. This manufacturing method specifies a step of preparing a single sheet-shaped plate without holes, and a first region surrounding the positions of some pins and a second region other than that from the entire region of the plate And a step of forming a hole for passing the pin only in the second region of the entire region of the plate.

The upper mold pin 3 is held so as to be movable up and down with respect to the upper mold 1 and to be fixed. The lower mold pin 4 is held so as to be movable up and down with respect to the lower mold 2 and to be fixed.

  As shown in FIG. 1, in the apparatus 100, a template 7 is disposed below the upper mold 1. A template 8 is disposed below the lower mold 2. The template 7 and the template 8 extend in a substantially horizontal direction in the apparatus 100. The templates 7 and 8 can move up and down along the guide rods 9 and 10 extending in the vertical direction based on driving of a driving device (not shown). At this time, the template 7 moves up and down with respect to the upper mold 1, and the template 8 moves up and down with respect to the lower mold 2.

  A plurality of guide rods 9 are provided on the left side of the device 100 and at a position closer to the center of the device 100 than the guide rod 5. A plurality of guide rods 10 are provided on the right side of the apparatus 100 at a position closer to the center of the apparatus 100 than the guide rod 6. Note that support frames 35 and 36 for supporting end portions of the templates 7 and 8 are attached to the guide rods 9 and 10, respectively.

  The apparatus 100 uses the templates 7 and 8 to select the upper mold pin 3 and the lower mold pin 4 that are used for separating the processing sheet 11. The sheet 11 is made of paper or plastic such as cardboard. Here, a configuration example of the processing sheet 11 will be described with reference to FIG.

  With reference to FIG. 4, the processing sheet 11 includes a product portion 12 and a residue portion 13. The product part 12 corresponds to a box-shaped part (not shown) used for packaging an article. The residue portion 13 corresponds to an unnecessary portion other than the product portion 12. In the processing sheet 11, a cut line 14 is provided in advance at the boundary between the product portion 12 and the residue portion 13 by cutting or the like. That is, in the sheet 11, the product portion 12 and the residue portion 13 are adjacent to each other with the cut line 14 interposed therebetween. A fold line 15 indicated by a broken line in FIG. 4 is also processed in advance.

  For ease of understanding, FIG. 4 shows an example in which only one product portion 12 is included in the processing sheet 11, but a plurality of product portions 12 are included in one processing sheet 11. It may be included.

  As shown in FIG. 3, the apparatus 100 accumulates a large number of processing sheets 11, and then punches out the product portion 12 to remove the residue portion 13. In order to punch out the product part 12 from the processing sheet 11, a pin for pressing the dregs part 13 from a large number of upper mold pins 3 is selected, and a pin for supporting the product part 12 from a large number of lower mold pins 4. It is necessary to sort out. Next, a configuration example of the upper mold 1 and the lower mold 2 that respectively hold the upper mold pin 3 and the lower mold pin 4 will be described.

(Configuration example of upper and lower molds)
A configuration example of the upper mold 1 will be described with reference to FIGS. 5 and 6. FIG. 5 is a cross-sectional view of the upper mold 1. FIG. 6 is a diagram schematically illustrating a state in which a part of the plurality of upper mold pins 3 is moved upward with respect to the upper mold 1.

The upper mold 1 has two pin boards B _{1 in} which a large number of pin holes H ₁ are formed. These pinboard B ₁ represents, vertically superimposed to relatively slide (see Fig. 6). In each pin board B ₁ , pin holes H ₁ having different inner diameters are alternately arranged. The average diameter of the pin hole H ₁ is set relatively small, and the spacing of the pin holes H ₁ adjacent to each other are relatively finely set. Incidentally, pinboard B ₁ of the upper mold 1 shown in FIG. 5 is a board that is disposed on the upper side of the two sheets.

As shown in FIG. 6, the upper die pin 3 is fitted in each pin hole H ₁ of the upper die ₁ . Upper die pins 3, while others a relatively size to fit the inner diameter of the pin hole H ₁ of the upper mold 1 large and small (not shown), and their average diameter is relatively small. Upper die pins 3 distance between the adjacent, in accordance with the spacing of the pin holes H _1, are relatively finely set. Each upper mold pin 3 is formed with notched grooves 3a and 3b. The groove 3 a is located at the upper part of the upper mold pin 3. The groove 3b is located below the upper mold pin 3.

By relatively sliding the two pinboard B ₁ of step is formed in two pin holes H ₁ edge overlapping vertically. Further, as shown in FIG. 5, escape holes S are formed in the pin holes H ₁ of the pin board B ₁ arranged on the upper side. Relief hole S is, in each pin hole H _1, a recessed portion in a direction pinboard B ₁ of the upper slides with respect to the pin board B ₁ lower. By relatively sliding the two pinboard B ₁ of the grooves 3a of the upper mold pins 3, 3b and can be locked in the gap without escape hole portion S at a time. Diameter of the escape hole S is smaller than the diameter of the pin hole H _1. The upper mold pin 3 is locked to the upper mold 1 by fitting the grooves 3 a and 3 b to the edge of the escape hole S. For example, in the state machine 100 (see FIG. 1) is not running (as this state for example, the initial state), the grooves 3a of the upper part of the upper die pins 3 are fitted to each pin hole H _1.

As shown in FIG. 6, among all the upper mold pins 3, the upper mold pin 32 that moves upward with the movement of the template 7 has the lower groove 3 b fitted in the pin hole H <b> ₁ . Thus, the upper mold pin 32 whose relative position changes with the upper mold 1 is disposed at the retracted position 18 so as not to be used for separating the processing sheet 11. On the other hand, among all the upper mold pins 3, the upper mold pin 31 that remains in the original position regardless of the movement of the template 7 has the upper groove 3 a fitted in the pin hole H ₁ . Thus, the upper die pin 31 whose relative position with respect to the upper die 1 does not change by passing through the hole 73 (described later) of the template 7 is placed at the work position 28 so as to be used for separation of the processing sheet 11. Left behind. The fitting between the groove 3a and the upper mold 1 and the fitting between the groove 3b and the upper mold 1 may be achieved at the same time.

  Next, a configuration example of the lower mold 2 will be described with reference to FIG. FIG. 7 is a diagram schematically illustrating a state in which a part of the plurality of lower mold pins 4 is moved upward with respect to the lower mold 2.

The basic configuration of the lower mold 2 is the same as that of the upper mold 1. That is, the lower mold 2 has a two-pin board B ₂ superimposed to slide relative to each other. Each pin board B ₂ has a large number of pin holes H ₂ . In each pin board B ₂ , pin holes H ₂ having different inner diameters are alternately arranged. The average diameter of the pin hole H ₂ is set relatively large, and the interval of the pin holes H ₂ adjacent to each other are set comparatively rough. Further, two the pin holes of H ₂ pinboard B ₂ disposed above of the pin board B _2, like the pin board B ₁ of the upper mold 1, relief hole portion.

For each pin hole H ₂ formed in the lower mold 2, a part or the whole of the pin hole H ₂ is partly or entirely of the pin hole H ₁ formed in the upper mold 1 and the device 100 (see FIG. 3). ) In a non-corresponding position in plan view.

The lower mold pin 4 is fitted in each pin hole H ₂ of the lower mold ₂ . Lower die pins 4, there is a small and relatively diameter large to fit the inside diameter of the pin hole of H ₂ lower mold 2 (not shown), and their average diameter is relatively large. Lower die pins 4 interval between the adjacent, in accordance with the spacing of the pin holes H _2, are set comparatively rough. In the drawing, the diameter of the upper mold pin 3 and the diameter of the lower mold pin 4 are shown as substantially the same size. Each lower mold pin 4 is formed with notched grooves 4a and 4b. The groove 4 a is located at the upper part of the lower mold pin 4. The groove 4 b is located below the lower mold pin 4.

The locking method of the lower mold pin 4 with respect to the lower mold 2 is the same as that of the upper mold 1. Of all the lower mold pins 4, the lower mold pins 41 that move upward with the movement of the template 8 have the lower grooves 4 b fitted into the pin holes H ₂ . Thus, the lower die pin 41 that does not move relative to the template 8 is disposed at the work position 29 so as to be used for separating the processing sheet 11. On the other hand, among all the lower mold pins 4, the lower mold pins 42 that remain in their original positions regardless of the movement of the template 8 have the upper grooves 4 a fitted in the pin holes H ₂ . Thus, the lower die pin 42 whose relative position with respect to the lower die 2 does not change by passing through the hole 83 (described later) of the template 8 remains in the retracted position 19 so as not to be used for separation of the processing sheet 11. It is. The fitting between the groove 4a and the lower mold 2 and the fitting between the groove 4b and the lower mold 2 may be achieved at the same time.

  The upper mold pin 31 disposed at the upper working position 28 by the selection of the upper mold pin 3 using the template 7 is a pin that presses the waste portion 13 when the processing sheet 11 is separated. The lower mold pin 41 disposed at the lower work position 29 by sorting the lower mold pins 4 using the template 8 is a pin that supports the product portion 12 from below when the processing sheet 11 is separated.

(About templates)
As described above, the arrangement patterns of the upper mold pins 3 and the lower mold pins 4 are determined by the templates 7 and 8, respectively. First, in order to deepen the understanding of the templates 7 and 8 in the present embodiment, a known template structure and manufacturing method will be briefly described. In addition, although the well-known template used for the upper mold | type 1 is demonstrated typically, the well-known template used for the lower mold | type 2 is also the same.

  FIG. 15 is a perspective view showing a known template 107. FIG. 16 is a longitudinal sectional view of a known template 107. Referring to FIGS. 15 and 16, the known template 107 used for the upper mold 1 is configured by sandwiching a template main body 170 c between two pin boards 170 a and 170 b.

Each of the pin boards 170a and 170b is a sheet-shaped plate, and a large number of holes h are formed in the entire region. Number of holes h is the same sequence as the pin hole H ₁ of the upper die 1, a through hole provided in correspondence with all of the upper die pins 3.

  The template main body 170 c is a single paper board having no holes, which is modeled so as to have a shape of a product part region 171 corresponding to the product part 12 of the processing sheet 11. That is, the template main body 170c closes the insertion hole of the upper mold pin 3 (32) to be moved to the retracted position 18 out of all the holes h of the pin board 170a. In the case of the template 8 for the lower mold pin 4, the insertion hole of the pin 4 (41) remaining at the work position 29 among the entire hole h of the pin board is closed by the template body.

  As a result, in the region (cass portion region) 172 other than the region (product portion region) 171 where the template main body 170c is arranged, the plurality of holes h of the bin boards 170a and 170c remain open. Therefore, when such a template 107 is used in the above-described apparatus 100, the upper mold pin 3 (32) that hits the template main body 170c moves to the retreat position 18 together with the template 107, and the other upper mold pins 3 (31) , Passes through the hole h of the template 107 and remains at the work position 28.

  The template main body 170c itself can be cut into various shapes without using any manual work, for example, by using a CAD system and a sample cutting machine. However, the work of fixing the template body 170c between the pin boards 170a and 170b is performed manually. Therefore, the operator has to carefully position the template main body 170c with respect to the pin boards 170a and 170b, which takes time and effort. Moreover, when the positioning error of the template main body 170c occurs, the processing sheet 11 cannot be properly separated, and there may be a case where the product becomes a defective product.

  On the other hand, the templates 7 and 8 of the present embodiment have a simple structure and do not require the above-described manual work. Therefore, even in the case where the apparatus 100 performs multi-product and small-quantity production, the templates 7 and 8 can be easily manufactured and replaced, so that productivity can be improved. Hereinafter, such templates 7 and 8 will be described in detail.

  The template 7 for the upper mold pin 3 will be described with reference to FIGS. 6, 8 and 9. FIG. 8 is a plan view schematically showing the template 7 for the upper mold pin 3. FIG. 9 is a cross-sectional view of the template 7 along the line IX-IX in FIG.

  As shown in FIGS. 8 and 9, the template 7 for the upper mold pin 3 is a single sheet-shaped plate 70, and has a product part region 71 and a residue part region 72. The product part region 71 corresponds to the product part 12 of the processing sheet 11 shown in FIG. 4, and the residue part region 72 corresponds to the residue part 13 of the processing sheet 11 shown in FIG. 4.

  More specifically, the product part region 71 of the plate 70 is the position of the upper mold pin 3 (that is, the whole part or part of the product part region 71 of the plate 70 can contact the product part 12 of the processing sheet 11 (that is, , A region surrounding the positions of pins to be separated from all the upper mold pins 3. Note that the upper mold pin 3 that can only partially contact the product portion 12 of the processing sheet 11, that is, the upper mold pin 3 whose position on the horizontal plane partially overlaps the product portion 12 is the boundary of the processing sheet 11. Interference pins (intermediate pins) straddling the line 14. On the other hand, the residue portion 72 is a region that surrounds the position of the upper pin that contacts only the residue 13 of the processing sheet 11 in the entire region of the plate 70.

In the template 7, a hole 73 through which the upper die pin 3 is inserted is formed only in the residue region 72 of the plate 70. The hole 73 is constituted by a large number of holes (hereinafter referred to as “individual holes”) h ₁ through which the plurality of upper mold pins 3 are individually passed. The size of individual holes h ₁ may be uniform.

In this manner, the scrap area 72, a plurality of discrete holes h ₁ to match the diameter of the upper die pins 3 for inserting are formed in a matrix. Therefore, even if a hole is made in one plate 70, when the end portion of the plate 70 (template 7) is supported by the support frame 35 of the apparatus 100, the product portion region 71 may drop off from the plate 70, The end of the partial area 71 does not hang down partially.

  Therefore, the template 7 composed of one plate 70 can be used for selecting the upper mold pins 3 in the same manner as the known template 107 shown in FIGS. 15 and 16. That is, when the template 7 is installed in the apparatus 100 and moved upward, as shown in FIGS. 2 and 6, the single sheet-shaped template 7 makes contact with the product part region 71 without holes. The mold pin 32 can be moved to the retreat position 18 and the other upper mold pin 31 can be left at the work position 28. In other words, the template 7 separates the pins 32 to be moved to the retreat position 18 from the upper mold pins 3 arranged in the same row.

  The template 8 for the lower mold pin 4 will be described with reference to FIG. 7, FIG. 10, and FIG. FIG. 10 is a plan view schematically showing the template 8 for the lower mold pin 4. FIG. 11 is a cross-sectional view of the template 7 along the line XI-XI in FIG.

  As shown in FIGS. 10 and 11, the template 8 for the lower mold pin 4 is also a sheet-shaped plate 80, and a product part region 81 corresponding to the product part 12 of the processing sheet 11, And a residue portion region 82 corresponding to the residue portion 13 of the processing sheet 11.

  More specifically, the product part region 81 of the plate 80 is the position of the lower mold pin 4 that contacts only the product part 12 of the processing sheet 11 in the entire region of the plate 80 (that is, all the lower mold pins 4). It is an area surrounding the pin position to be separated from the inside. On the other hand, the debris portion region 82 is a region surrounding the position of the lower die pin 4 that can be entirely or partially brought into contact with the debris portion 13 of the processing sheet 11 in the entire region of the plate 80.

  As described above, in the template 8, the position of the interference pin straddling the boundary line 14 of the processing sheet 11 in the lower mold pin 4 is included in the residue portion region 82. Therefore, typically, the area of the product part region 81 of the template 8 is smaller than the area of the product part region 71 of the template 7, and the area of the residue part region 82 is larger than the area of the residue part region 72 of the template 7. large.

Also in the template 8, a hole 83 for inserting the lower mold pin 4 is formed only in the dregs region 82 of the plate 80. Hole 83 is constituted by a number of individual holes h ₂ for passing a plurality of the lower die pins 4 individually. The size of individual holes h ₂ may be uniform. Since the average diameter of the lower mold pin 4 is larger than the average diameter of the upper mold pin 3, the inner diameter of the individual hole h ₂ of the template 8 is larger than the inner diameter of the individual hole h ₁ of the template 7.

Thus, also in the template 8, since the matrix-shaped individual holes h ₂ are formed in the residue portion region 82, the end portion of the plate 80 is supported by the support frame 36 of the apparatus 100 as described above. Further, the product part region 81 does not fall off from the plate 80, and the end part of the product part region 81 does not partially hang down.

  Therefore, the template 8 composed of one plate 80 can be used for selecting the lower mold pins 4 in the same manner as a known template for lower mold pins. That is, when the template 8 is installed in the apparatus 100 and moved upward, as shown in FIG. 2 and FIG. 7, the sheet 8 is in contact with the product part region 81 without holes. The mold pin 41 can be moved to the working position 29 and the other lower mold pins 42 can be left at the retracted position 19. In other words, the pins 8 to be moved to the work position 29 are separated from the lower mold pins 4 arranged in the same row by the template 8.

  Such manufacture of the templates 7 and 8 can be realized by the following method, for example. FIG. 12 is a flowchart showing the manufacturing process of the templates 7 and 8. Here, the method for manufacturing the template 7 will be described as a representative, but the method for manufacturing the template 8 is basically the same.

  Referring to FIG. 12, first, a sheet-shaped plate 70 having no holes is prepared (step P1). The plate 70 only needs to have a certain degree of strength, and the material is not particularly limited. For example, the plate 70 may be a resin thin plate or cardboard or other thick paper. The material of the plate 80 of the template 8 is the same.

  Next, the product part region 71 and the other waste part region 72 are specified from the entire region of the prepared plate 70 (process P2). This specific work is performed based on, for example, CAD data. Specifically, the product part region 71 and the residue part region 72 are specified based on the shape of the product part 12 of the processing sheet 11 using dedicated CAD software.

  At this time, as described above, it is desirable to specify the regions 71 and 72 so that the position of the interference pin is included in the product part region 71. In the case of the template 8, it is desirable to specify the regions 81 and 82 so that the position of the interference pin is included in the residue portion region 82.

When a particular region 71, 72 is performed, only the scrap area 72 of the entire area of the plate 70, as the hole portion 73, a plurality of discrete holes _{h 1} is formed (step P3). The hole 73 is automatically formed by a cutting machine such as a sample cutter machine or a laser processing machine. The diameter of the individual hole h ₁ is determined according to the diameter of the upper mold pin 3.

  As described above, the template 7 of the present embodiment can be manufactured roughly by performing the above three steps. Therefore, unlike the conventional template 107, manual work for attaching the template main body 170c to close the hole h is not necessary. Therefore, the labor of the operator can be reduced. Moreover, since the positioning error by the operator can be prevented, the separation accuracy of the processing sheet 11 can be improved.

  In addition, since the operator does not need to paste the template main body 170c, a unique technique for manufacturing the template becomes unnecessary. As a result, the time required for template manufacture is greatly shortened, so that the productivity of the box-shaped part (the product part 12 of the processing sheet 11) can be improved.

In this embodiment, the hole portion 73 formed in the scrap portion region 72, it is assumed that is composed by a small discrete holes h ₁ formed so as to insert the upper die pins 3 individually, Limited Not right. For example, as shown in FIG. 13, the hole 73 may partially include a relatively large hole (hereinafter referred to as “integrated hole”) h ₃ through which the plurality of upper mold pins 3 are collectively passed. If integrated hole h ₃ are provided a plurality, size and shape of the integrated holes h ₃ it may not be unified.

Template 7A shown in FIG. 13, as an example, among the debris area 72, four integrated holes h ₃ provided at a position adjacent to the product area 71, a number of discrete holes provided in other positions It is composed of a h _1. In order to maintain the strength of the plate 70 and the like, it is desirable that an individual hole h ₁ is provided at a position along the outer peripheral portion of the plate 70 instead of the integrated hole h ₃ .

Alternatively, as a template 7B of FIG. 14, the hole 73 does not include a separate hole h _1, may be constituted by only integrate hole h ₄ through together a plurality of pins 3. In this case, it is desirable that some of the integrated holes h ₄ are relatively small holes through which a small number (for example, 5 or less) of the pins 3 pass.

When the hole portion 73 includes the integrated hole h ₃ or h ₄ , the size and position of these integrated holes h ₃ and h ₄ may be such that the product part region 71 falls off from the plate 70 or the end of the product part region 71. The part may be selected so that the part does not hang down partially.

  Further, in the present embodiment, the processing sheet 11 includes only one product part 12 for easy understanding, but the processing sheet 11 may include a plurality of product parts 12. In that case, each template 7 (8) includes a plurality of product part regions 71 (81). Further, the cusp region 72 (82) is divided into a plurality of regions, not a continuous region. The plurality of product part regions 71 (81) may be separated from each other or may be partially connected. Also in this case, the holes 73 (83) are arranged so that the plurality of product part regions 71 (81) arranged in an island shape in the plate 70 (80) are connected via the residue part region 72 (82). Is preferably formed.

  In the present embodiment, the regions 71 and 72 are specified so that the position of the interference pin to be retracted is not included in the dregs region 72 of the template 7 for the upper pin 3. It is not limited to such an example. That is, the product part region 71 and the residue part region 72 of the template 7 may be the shapes of the product part 12 and the residue part 13 of the processing sheet 11, respectively. Similarly, in the template 8 for the lower mold pin 4, the product part region 81 and the residue part region 82 of the template 8 may have the shapes of the product part 12 and the residue part 13 of the processing sheet 11, respectively. In that case, when the position of the interference pin is separately specified in each of the upper mold pin and the lower mold pin and the processing sheet 11 is separated, the interference pin may be retracted in advance by some method.

  Further, the templates 7 and 8 described above are used in the scrap removing device 100 including the upper die pin 3 and the lower die pin 4 as shown in FIG. However, the structure and manufacturing method of the templates 7 and 8 described above is a type of casket that distributes a single pin to an upper substrate and a lower substrate as disclosed in, for example, Japanese Patent Application Laid-Open No. 11-5262 (Patent Document 3). It can also be applied to a take-off device. In other words, if the template defines a pin arrangement pattern for separating the processing sheet 11 into the product portion 12 and the residue portion 13 in a pinboard type residue removing device, the configuration of the device itself is particularly limited. Not.

  Further, in the present embodiment, the pin separation template is used for selecting the depressing portion pressing pin, the product portion supporting pin, or the interference pin, but is not limited thereto. The pin separation template is applicable when a part of pins is separated from a plurality of pins arranged in the same row for processing a certain workpiece. In this case, the pin separation template specifies the region (first region) surrounding the position of the pin to be separated from among the plurality of pins and the other region (second region), and the hole is formed only in the second region. Can be created.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
