Description of the Related Art A technique for manufacturing a product having a predetermined shape (for example, a rectangle) by punching with a mold while intermittently conveying a long workpiece is widely used. As one of such techniques, a technique of sequentially loading products manufactured by punching on a lower mold is known. (For example, refer to Patent Document 1).
JP 2001-105430 A

  By the way, some manufactured products have holes. When punching such a product with a hole, generally, the part corresponding to the hole is punched at the same time. In this case, the part punched to make the hole (“fog”) will fall. For this reason, in the technology of loading the product on the lower mold, there is a problem that “debris” is also accumulated in the lower mold and “debris” is mixed into the product.

  In view of the above circumstances, the present invention can be used to manufacture a plate-like member (product) having a hole without mixing “debris” and the product, and in a state where a plurality of plate-like members are stacked. It is an object of the present invention to provide a plate-shaped member manufacturing apparatus and a plate-shaped member manufacturing method capable of easily packing products.

In the plate member manufacturing method for continuously manufacturing a sheet of plate members,
(11) The plurality of plate-shaped members are still stacked in the stacking space formed on the die plate, and the hole punch is penetrated through the plurality of plate-shaped members. The plurality of plate-shaped members are manufactured by punching a workpiece.

here,
(12) When the workpiece is punched by the die plate and the outer shape punch, the workpiece may be pressed against the die plate and the outer shape punch.

further,
(13) A plurality of plate-like members loaded in the loading space may be dropped with compressed air.

  Examples of the resin used in the present invention include polyethylene, nylon, and polypropylene.

  According to the present invention, the resin workpiece is punched out by the die plate and the outer shape punch, and the outer shape (overall shape) of the plate member (product) is formed (formed). When the outer shape of the product is formed, a hole is made in the product (or workpiece) by the hole punch at the same time. When punching a workpiece with a die plate and an outer shape punch, the peripheral portion (outer peripheral portion) of the resin workpiece is temporarily bent, and then the bent portion is the original. Restore to the state. For this reason, the shape (planar shape) of the product is slightly (slightly) larger than the opening of the die plate. Similarly, when a hole is made in a product (or workpiece) with a hole punch, the peripheral portion of the resin product (or workpiece) where the hole is opened by the hole punch is temporarily bent. After drilling, the inner diameter of the hole in the product is slightly (slightly) smaller than the outer diameter of the hole punch. Thus, the outer size (dimension) of the punched product is slightly larger than the opening of the die plate, and the inner diameter of the hole opened in the product is slightly smaller than the outer diameter of the hole punch. For this reason, since the product fits into the opening of the die plate and the hole punch fits into the hole of the product, the product does not drop (drop) from the opening due to the frictional resistance between them. After punching one workpiece in this way, the workpiece is then transported and stopped by a distance slightly longer than the length of the product, and again the workpiece by the die plate and the outer shape punch. At the same time, the product is punched with a punch for punching. As a result, the preceding product is loaded in the upper mold loading space so as to overlap the succeeding product. By repeatedly punching the workpiece in this manner, a plurality of products (plate-like members) are stacked in a stacking space communicating with the opening. In addition, the portion (debris) cut out by the hole punch falls into a residue insertion hole opened in the lower die outer shape punch. For this reason, debris is not mixed into a plurality of plate-like members stacked on the upper mold. Since the plurality of formed plate-shaped members are stacked in the stack space of the die plate, they can be pushed out from the stack space of the die plate when the number of stacked plate-shaped members reaches an appropriate number. At the time of taking out, since a plurality of plate-like members can be taken out in a stacked state, the plurality of plate-like members can be directly stored in a storage box or the like in an aligned state, facilitating product packing work. it can.

  The present invention has been realized in a plate member manufacturing apparatus for manufacturing a rectangular plate member having a plurality of holes.

  With reference to FIG. 1, the manufacturing unit in which the plate-shaped member manufacturing apparatus of the present invention is incorporated will be described.

  FIG. 1 is a side view showing a schematic configuration of a manufacturing unit in which a plate-shaped member manufacturing apparatus of the present invention is incorporated.

  The plate-shaped member manufacturing apparatus 10 is an apparatus for punching a resin workpiece W to manufacture a plurality of plate-shaped members T (see FIG. 9 and the like). The workpiece W is a long material wound around the material unwinding hanger 100 in a roll shape. The workpiece W is pulled out while being sandwiched between the roll feeders 140. Between the material unwinding hanger 100 and the roll feeder 140, a guide device 110 that holds the workpiece W lightly, a mold 120 (an upper die 20 and a lower die 60) for punching the workpiece W, and the like are arranged. Yes. An appropriate tension is applied to a portion of the workpiece W between the guide device 110 and the roll feeder 140. The lower die 60 includes a lower base (lower die set) 62, and most of other members are detachably fixed to the lower die set 62 as described later. The lower mold 60 does not move while punching the workpiece W. The upper mold 20 includes an upper base (upper die set) 22, and most of other members are fixed to the upper die set 22 as described later. The upper die set 22 is fixed to four guide posts 122 (only two are shown in the figure), and moves up and down in the direction of arrow A together with the guide posts 122. A drive source and a drive system (not shown) for moving the guide post 122 up and down are disposed inside the base 124 below the lower die set 62. For this reason, machine oil or the like used in the drive source or drive system does not adhere to the molds (upper mold 20 and lower mold 60).

  The workpiece W fed from the material unwinding hanger 100 passes through the guide device 110 and passes between the upper mold 20 and the lower mold 60 and reaches the roll feeder 140. After the workpiece W passes between the upper mold 20 and the lower mold 60, it becomes scrap, and this scrap is wound on the scrap winding hanger 150. Since the features of the present invention reside in the upper mold 20 and the lower mold 60, this point will be described with reference to the drawings.

  A mold composed of an upper mold and a lower mold will be described with reference to FIGS.

  FIG. 2A is a perspective view illustrating a portion of the upper mold that contacts the workpiece W, and FIG. 2B is a perspective view illustrating a portion of the lower mold that contacts the workpiece W. FIG. 3 is a cross-sectional view showing a side surface of the upper die of FIG. 2A cut along AA and the lower die of FIG. 2B cut along BB. 2 is a diagram schematically showing the upper mold and the lower mold, and some of the components shown in FIG. 3 are omitted in FIG.

  As described above, the upper die 20 includes the plate-like upper die set 22 to which various members constituting the upper die 20 are fixed. When punching the workpiece W, a drive system (not shown) Thus, the upper die set 22 and various members are moved up and down. The upper die set 22 has a plurality of holes 22a (only two are shown in FIG. 3) penetrating from the upper surface (not shown) to the lower surface 22c. As will be described later, an extraction rod (shaft) for taking out the plate-like member T loaded in the loading space 30a is inserted into the plurality of holes 22a.

  A height adjustment plate 24 for adjusting the height of the upper mold 20 and the like is fixed to the lower surface 22 c of the upper die set 22. A space 24a is formed at the center of the height adjusting plate 24, and the height adjusting plate 24 has a "mouth" shape surrounding the space 24a. A plate-like backing plate 26 having a plurality of through holes extending in the vertical direction (arrow A direction) is fixed to the lower surface of the height adjustment plate 24. Further, a plate-like punch holder 28 to which the upper end portion of the hole punch 42 is fixed is fixed to the lower surface of the backing plate 26. The punch holder 28 is formed with through holes connected to the plurality of through holes of the backing plate 26. A die plate 30 is fixed to the lower surface of the punch holder 28. That is, the upper die 20 has a die plate 30, a punch holder 28, a backing plate 26, a height adjusting plate 24, and an upper die set 22 stacked in this order and fixed with bolts or the like.

  By appropriately changing the thickness t of the height adjustment plate 24, the height of the upper mold 20 is adjusted. The space 24a of the height adjustment plate 24 is surrounded by the upper die set 22, the height adjustment plate 24, and the backing plate 26. Inside the space 24a, there is an extrusion plate 34 and a knockout spring 36 (referred to in the present invention). Which is an example of a urging means for knockout). The extrusion plate 34 is a plate-like member having a plane having the same width as the transverse section of the space 24a (a section when cut in a direction orthogonal to the arrow A direction). A groove (not shown) is formed in the inner wall of the height adjustment plate 24 so that the extrusion plate 34 can freely move in the direction of arrow A in the space 24a, and a part of the extrusion plate 34 is in this groove. It is inserted.

  An upper end of a knockout spring 36 is fixed to the lower surface 22 c of the upper die set 22, and this lower end is fixed to the upper surface of the extrusion plate 34. Therefore, the pushing plate 34 is always urged downward (toward the lower die 60) by the knockout spring 36. In other words, the knockout spring 36 urges the knockout 32 from the back of a loading space 30a described later toward the opening 30b. The urging force of the knockout spring 36 is weaker than the frictional force of the die plate 30 and the hole punch 42 against a single plate-like member T (see FIG. 5 and the like) described later.

  A plurality of through holes penetrating from the upper surface to the lower surface are connected to the backing plate 26 and the punch holder 28, and a plurality of parallel pins 38 for knockout (described later) are formed in the plurality of through holes. , Only two are shown) and a plurality of push pins 40 (only three are shown in the figure) are movably inserted.

  The punch holder 28 located under the backing plate 26 is a plate-like one that is thinner than the backing plate 26. On the contrary, the backing plate 26 may be thinner than the punch holder 28, or both may have the same thickness. The hole punch 42 whose upper end is fixed to the punch holder 28 extends downward, and its tip is located on the same plane as the lower surface of the die plate 30 (positioned in the opening 30b).

  The knockout parallel pin 38 is for guiding the knockout 32 parallel to the direction of the arrow A so that the knockout 32 moves in parallel without being inclined. The knockout parallel pin 38 is inserted into the through holes of both the backing plate 26 and the punch holder 28 and moves in these through holes. The upper end of the knockout parallel pin 38 is a free end, and the lower end is fixed to the knockout 32. The knockout parallel pin 38 moves up and down through the through holes of both the backing plate 26 and the punch holder 28 as the knockout 32 moves up and down. Since the backing plate 26 is relatively thick, the hole into which the knockout parallel pin 38 is inserted extends long in the vertical direction (arrow A direction), and the knockout 32 is accurately guided in the vertical direction. When the knockout 32 is at the lowest position, the upper end of the knockout parallel pin 38 hardly protrudes from the backing plate 26 as shown in FIG. On the other hand, when the knockout 32 is located at the uppermost position, as shown in FIG. 8, the upper end portion of the knockout parallel pin 38 protrudes from the backing plate 26 and is located in the space 24a.

  The push pin 40 transmits the urging force of the knockout spring 36 to the knockout 32 via the push plate 34. The upper end of the push pin 40 is fixed to the lower surface of the push plate 34, and the lower end is fixed to the upper surface of the knockout 32. Although it is not necessary to fix the upper end and the lower end of the extrusion pin 40 to the extrusion plate 34 and the knockout 32, in this case, in order to prevent the knockout 32 from dropping, Is formed in the die plate 30.

  The die plate 30 cuts the workpiece W in cooperation with the outer shape punch 66 of the lower mold 60. For this reason, the die plate 30 has an opening 30b having the same shape as the planar shape of the plate member T (product). A loading space 30a in which a plurality of plate-like members T are loaded is formed in communication with (connected to) the opening 30b. The loading space 30a is located above the opening 30b, and in the vicinity of the opening 30b has substantially the same cross-sectional area as the opening 30b, but in the upper part (the back part) away from the opening 30b than the opening 30b ( The cross-sectional area is wider than the plane of the plate-like member T (product). The reason for this is to prevent the hole punch 42 from receiving an uneven force from the plurality of stacked plate-like members T when the plurality of plate-like members T are stacked in the stacking space 30a. Details will be described later.

  The knockout 32 presses the workpiece W against the outer shape punch 66 when the workpiece W is punched out. In a state where no workpiece W has been punched, the lower surface 32a of the knockout 32 is flush with the opening 30b and is flush with the lower surface 30c of the die plate 30. However, when the workpiece W is punched and the number of plate-like members T increases, as shown in FIGS. 7 and 8 to be described later, the plate-like member T and the die plate 30 and the hole punch 42 are connected. Since the frictional force is larger than the urging force of the knockout spring 36 (because the urging force is overcome), the knockout 32 moves from the position closing the opening 30b to the back of the loading space 30a.

  The hole punch 42 is inserted into a through hole formed in the knockout 32 and moves together with the die plate 30 to open a hole in the workpiece W. During punching, the entire upper die 20 moves up and down, but the hole punch 42 is fixed to the punch holder 28 and is fixed to the die plate 30 and does not move.

  As described above, the lower mold 60 includes the plate-shaped lower die set 62 to which various members constituting the lower mold 60 are fixed. When the workpiece W is punched, the lower mold 60 moves as a whole. Absent. The lower die set 62 is formed with a hole 62a in which a portion (“debris”) punched by the hole punch 42 of the workpiece W falls. A low cylindrical punch holder 64 is fixed to the upper surface of the lower die set 62. An outer shape punch 66 higher than the punch holder 64 is fixed with a bolt or the like in the central space of the punch holder 64 and on the upper surface of the lower die set 62. The outer shape punch 66 is formed with a grazing hole 66b connected (connected) to the hole 62a of the lower die set 62. The upper part of the hole 66b is a thin punching hole 66a, and when the workpiece W is punched, the tip (lower end) of the hole punch 42 slightly enters. For this reason, the “poison” falls into the punching hole 66a and is discharged through the pouring hole 66b and the hole 62a.

  A lower end of a stripper spring (coil spring) 68 is fixed to the upper surface of the punch holder 64. The upper end of the stripper spring 68 is fixed to the lower surface of the annular stripper plate 70. For this reason, the stripper plate 70 is always biased upward (toward the die plate 30) by the stripper spring 68. When punching out the workpiece W, the punch holder 64 and the outer shape punch 66 are fixed to the upper surface of the lower die set 62 with bolts or the like, so that the stripper plate 70 is moved downward by the pressing force from the upper die 20. When the pressing force disappears, the stripper plate 70 returns to the original position (position shown in FIG. 3) by the urging force of the stripper spring 68. The stripper spring 68 is fitted into a straight portion (a portion where no screw is formed) of the strip bolt 72 whose tip is screwed into the stripper plate 70 so as not to fall off.

  The operation of punching a workpiece with the upper mold and the lower mold will be described with reference to FIGS.

  FIG. 4 is a cross-sectional view showing a state in which one workpiece is manufactured by punching the workpiece W from the side. FIG. 5 is a cross-sectional view from the side showing a state in which the upper die is raised after the plate member is manufactured and the workpiece W can move in the direction of arrow D. FIG. 6 is a cross-sectional view from the side showing a state in which the workpiece W is punched out to produce and laminate two plate-like members. FIG. 7 is a cross-sectional view showing a state in which a plurality of plate-like members are laminated in a lamination space from the side. FIG. 8 is a cross-sectional view showing a state where the lower mold is removed and the storage box is disposed under the upper mold from the side. FIG. 9 is a cross-sectional view showing a state in which a plurality of plate-like members are stored in a storage box from the side. In each figure, the thickness of the plate-like member is increased to make it easy to see, but in actuality it is very thin (for example, 0.05 mm or less) and about 100 sheets can be stacked in the stacked space 30a.

  When a plurality of plate members T (products) are manufactured by continuously punching the workpiece W, the workpiece W is intermittently conveyed between the upper mold 20 and the lower mold 60. After the workpiece W is temporarily stopped, as shown in FIG. 4, the upper mold 20 is lowered, and the workpiece W is moved by the inner corner portion 30 d of the knockout plate 30 and the outer corner portion 66 c of the outer shape punch 66. At the same time as punching into the plate member T, a hole is made in the workpiece W by the hole punch 42. In this case, the knockout 32 of the upper die 20 is slightly pushed up (about a little longer than the thickness of the workpiece W) by the outer shape punch 66 of the lower die 60 against the urging force of the knockout spring 36. On the other hand, the stripper plate 70 of the lower mold 60 is slightly pushed down (about a little longer than the thickness of the workpiece W) by the die plate 30 of the upper mold 20 against the urging force of the stripper spring 68. The state at this time is shown in FIG.

  When the workpiece W is punched out by the die plate 30 and the outer shape punch 66 as described above, the peripheral portion (outer peripheral portion) of the portion of the resin workpiece W that becomes the product shape is temporarily bent, Thereafter, the bent portion is restored to the original state. For this reason, the shape (planar shape) of the plate-like member T is slightly (slightly) larger than the opening 30 b of the die plate 30. Similarly, when a hole is made by the hole punch 42 or in the workpiece W (plate member T), the peripheral portion of the portion of the resin workpiece W where the hole is to be opened by the hole punch 42 is temporarily set. Therefore, the inner diameter of the hole of the product is slightly (slightly) smaller than the outer diameter of the hole punch 42 after bending. Thus, the outer size (dimension) of the product manufactured by punching is slightly larger than the opening 30b of the die plate 30, and the inner diameter of the hole opened in the plate member T (product) is the hole punch 42. Slightly smaller than the outer diameter. For this reason, since the plate-like member T (product) is fitted into the opening 30b of the die plate 30 and the hole punch 42 is fitted into the hole of the plate-like member T, as shown in FIG. When there is not, the plate-like member T does not drop (drop) from the opening 30b due to the frictional resistance between them.

  After the workpiece W is punched and a single plate-like member W is manufactured, as shown in FIG. 5, the upper die 20 is raised and separated from the lower die 60. Subsequently, the workpiece W is The workpiece W is transported and stopped by a distance slightly longer than the length of the shaped member T, and the workpiece W is punched again by the die plate 30 and the outer shape punch 66, and at the same time, a hole is made in the product by the hole punch 42. As a result, as shown in FIG. 6, the preceding product (T1) is loaded on the loading space 30a of the upper mold 20 so as to overlap the succeeding product (T2). By repeatedly punching the workpiece W in this manner, as shown in FIG. 7, a plurality of products (plate-like members) T are stacked in the stacking space 30a communicating with the opening 30b.

  Further, as shown in FIG. 7 and the like, the portion (debris) WK cut by the hole punch 42 falls into the punch hole 66a opened in the outer shape punch 66 of the lower mold 60, passes through the hole 66b, It falls into the hole 62a of the lower die set 62 and is discharged. For this reason, the waste WK is not mixed into the plurality of plate-like members T stacked on the upper mold 20.

  Since the plurality of formed plate-like members T are loaded in the loading space 30a of the die plate 30, the loading space 30a of the die plate 30 is reached when the number of loaded plate-like members T reaches an appropriate number. Can be pushed out When this is taken out, as shown in FIG. 8, the lower mold 60 is moved from below the upper mold 20 (or the upper mold 20 is raised until the storage box 80 can be placed under the upper mold 20). A storage box 80 is placed underneath, and an extraction rod (not shown) is inserted in the plurality of holes 22a of the upper die set 22 from above in the direction of arrow H, and the extrusion plate 34 is pushed downward. As shown in FIG. 9, the urging force of the knockout spring 36 is applied to the pushing force, so that the knockout 32 moves downward together with the push pin 40, and the plate member T in the loading space 30a is pushed out of the loading space 30a. And is stored in the storage box 80. Since the plurality of plate-like members T can be taken out in a stacked state in this way, the plurality of plate-like members T can be directly stored in the storage box 80 or the like in an aligned state, and the product can be easily packed. it can.

  With reference to FIG. 10, another example of the mold will be described.

  FIG. 10 is a cross-sectional view showing another example of a mold. In these drawings, the same components as those shown in FIGS. 3 to 9 are denoted by the same reference numerals.

  The feature of this mold is in the upper mold 220, and the lower mold 60 is the same as that described with reference to FIGS. Two types of compressed air flow paths 222 and 224 are formed in the upper mold 220. The compressed air flow path 222 is formed continuously with the backing plate 26 and the punch holder 28, and is for introducing compressed air into the stacking space 30a from the outside. Note that the compressed air flow path 222 may be formed only in the punch holder 28. The compressed air flow path 224 is formed in the knockout 32, and is for ejecting the compressed air introduced into the loading space 30a from the surface of the knockout 32.

  As shown in FIG. 8, when a plurality of plate-like members T are stacked in the loading space 30 a, the uppermost plate-like member of the plurality of plate-like members T is in close contact with the surface of the knockout 32. There may be. In this case, as shown in FIG. 9, the uppermost plate-like member among the plurality of plate-like members T may not be smoothly separated from the surface of the knockout 32. Therefore, in order to smoothly separate all of the plurality of plate-like members T from the upper mold 220 (that is, from the surface of the knockout 32), the compressed air is introduced into the loading space 30a through the compressed air flow path 222. From the surface of the knockout 32 through the compressed air flow path 224. A part of the compressed air introduced into the loading space 30a escapes to the outside through a gap (for example, a gap between the punch holder 28 and the die plate 30), but since these gaps are very narrow, most of the compressed air flows It ejects from the surface of the knockout 32 through the path 224. As a result, even if the uppermost plate-like member of the plurality of plate-like members T is in close contact with the surface of the knockout 32, the uppermost plate-like member can be smoothly separated from the surface of the knockout 32. it can.
