Description

  The present invention relates to a product member layer layer (hereinafter referred to as “member layer”) formed by two plate-like members, particularly by using a fitting member manufactured by a specific method, a precursor thereof, and a part of the precursor. In the process of caulking, the formation of the fastening member and the caulking of the member layer are performed simultaneously.

  Conventionally, two plastic plate members are caulked with a synthetic resin fitting (in this specification, this noun notation is expressed in Chinese characters as “end stop” for easy reading). A technique (in the same manner as described above, written in kanji as “clamping” in order to make this verb expression easy to read at a glance) is known from Japanese Patent Laid-Open No. 2000-179518.

According to this known technique, the synthetic resin end stop member is composed of a head and a leg, and the leg is formed thick from the bottom of the head to the middle, and thin from the middle to the tip. As a result, the leg portion is less likely to buckle during caulking, and the tip is easily curled.
JP 2000-179518 A

  However, such resin end-stop members usually have to be manufactured one by one by injection molding, and there is a limit to improving the productivity. Further, when performing the caulking operation of the member layer, the end stopper members must be positioned one by one at a predetermined position of the member layer, and then the tip of the end stopper member must be crushed with a caulking jig. This has the problem that the positioning of the end stop member becomes unstable.

  Therefore, the present inventor diligently researched an end stopper member that can solve this problem and a caulking method using the end stopper member. As a result, depending on the application in which the end stopper member is used, the inventor is completely different from the known technique. Adopting a manufacturing method of an end stop member, using a precursor in a stage before the end stop member is completed, the component of the precursor that becomes the end stop member at the forefront of the precursor is passed through the member layer. The present invention has been completed by finding the fact that, after positioning the hole, the component may be crimped to the member layer and simultaneously separated from the precursor.

  Accordingly, an object of the present invention is to manufacture an end stop member used in a specific field by a novel method, and to use the precursor in a stage before the end stop member is completed, to stop the end stop member from the precursor. The object is to propose a method of caulking a member layer simultaneously with forming a member.

  In order to solve the above-described problems, the present invention provides a substrate portion made of a plastic synthetic resin having a predetermined thickness and an outer shape and a substantially central portion of the substrate portion. An end stop member comprising a short cylindrical portion formed so as to be reduced in diameter is provided.

  The end stop member having such a structure forms a plurality of constricted portions at a predetermined interval on a tape or sheet-like substrate made of a plastic synthetic resin having a predetermined thickness, and other than the constricted portions. By preparing a precursor formed by vertically forming a short cylindrical portion whose diameter is reduced as the outer peripheral surface goes to the tip, by drawing it at a substantially central portion of each of the plurality of substrate portions which are non-constricted portions can get.

  Such a precursor includes a first step of preparing a plastic synthetic resin tape or sheet-like base material having a predetermined thickness, and a plurality of parts that are separated from each other at a predetermined interval by partially cutting the base material. A second step of forming a constricted portion, a third step of supplying the base material between a pair of upper and lower upper and lower molds, and drawing a substrate portion that is a portion of the substrate where the constricted portion does not exist. It is manufactured through a fourth step of vertically forming a plurality of short cylindrical portions whose diameter is reduced as the outer peripheral surface reaches the tip.

  And, as the tape or sheet-like base material, preferably used is one having a guide hole that guides the end face formation of the short cylindrical portion at a central portion in the width direction, separated by a predetermined distance in the longitudinal direction of the base material In addition, the second step employs a method for manufacturing a precursor for an end stop member that is performed simultaneously with the fourth step between the upper and lower molds after the third step.

  And while using this precursor, a part of the precursor is caulked, for example, the caulking member in the process of caulking a member layer formed from the first plate-like member and the second plate-like member Is produced. That is, a first step of providing a plurality of constricted portions at a predetermined interval on a plastic synthetic resin tape or sheet-like substrate having a predetermined thickness, and a plurality of non-constricted portions other than the constricted portions A second step of forming a short cylindrical portion by drawing it at a substantially central portion of the substrate portion, and a third step of providing a through hole in at least the first plate member and / or the member layer of the second plate member A step, a fourth step of inserting the short cylindrical portion into the through hole from one surface side of the member layer, and projecting the tip portion to the other surface side, and the presence of the constricted portion on the tape or sheet-like base material The end stopper member is formed by adopting a method including a fifth step of breaking at a part and a sixth step of expanding the tip portion protruding from the member layer outward and crushing downward.

  In this method, the fifth step becomes an end stop member that is a part of the precursor by performing the fourth step or the sixth step at the same time or after the steps are performed. Since positioning of the component becomes possible, it is possible to hold a portion other than the component in the hand or to be gripped by an operating machine, and the positioning is stabilized.

  Thus, the end stop member separated from the precursor and crimped in the through hole of the member layer protrudes from the member layer and expands outward and is crushed downward. Is inevitable that it is inferior to that of a metal end stopper. Therefore, in the present invention, rather than aiming at the end effect of the member layer with respect to the end member, the development of applications is mainly aimed at protecting the peripheral end surface of the through hole of the member layer. Completed the invention of application.

  That is, the first plate-like member is a resin blister member having a bulge portion that covers a packaged article placed on a mount that is a two-plate-like member, and there is no bulge portion of the first plate-like member. If the method is applied to the member layer formed by the part and the second plate-like member to protect the through hole, the end stopper member according to the present invention has a periphery of the through hole than the metal end stopper member. End face protection performance is demonstrated effectively.

  INDUSTRIAL APPLICABILITY The present invention can provide a novel manufacturing method of a precursor for an end stop member that can efficiently form an end stop member used in a specific field, and a member layer to be crimped when the precursor is used. The end stop member can be easily positioned with respect to the through hole.

(End stop member)
Next, the best embodiment of the present invention will be described with reference to the drawings. First, the end stop member according to the present invention will be described. As shown in FIG. 1, the end stop member 9 according to the present invention has a predetermined thickness T and a rectangular shape or a circular shape or a non-circular shape by trimming a rectangular peripheral portion. For example, a substrate portion 11 made of a plastic synthetic resin having various outer shapes S1 such as a polygonal shape or a petal shape, and a polygon or a petal whose cross section rising substantially vertically from a substantially central portion C of the substrate portion 11 is circular or noncircular. It is formed from a short cylinder portion 12 having various outer shapes S3 such as shapes. In FIG. 1, an embodiment composed of a rectangular substrate portion 11 and a circular short tube portion 12 is depicted, and a constricted portion 10 described later is broken at one edge portion of the substrate portion 11, and a part thereof. The state accompanying the substrate part 11 is depicted.

  The short cylinder portion 12 is formed through a process of forming a precursor for an end stop member, which will be described later. In principle, the short cylinder portion 12 is obtained through the following steps. First, as shown in FIG. 2, in order to form the end surface 12a of the short cylindrical portion 12 in the central portion C of the substrate portion 11, a guide through hole 2 is formed, and a portion around the guide through hole 2 is moved up and down. Place between molds 3 and 4. Of the upper and lower molds 3, 4, the central projection 5 a of the male part 5 is made to face the guide through-hole 2 and the drawing is performed. Then, the vicinity of the induction through hole 2 of the substrate portion 11 starts to undergo plastic deformation. When the drawing is further continued, as shown in FIG. 3, the plastic deformation of the plastic deformation portion continuously occurs, and finally the short cylinder portion 12 between the male portion 5 and the female portion 6 of the upper and lower molds 3, 4. Is completed.

  Since the end stopper member 9 according to the present invention is obtained in this way, the material used for forming the short tube portion 12 is the wide shape of the inner shape S2 of the short tube portion 12 at the base end portion 11 before drawing. Since the end stop member 9 is a material corresponding to the thickness, the end stop member 11 having the narrower inner shape S2 has to have a smaller thickness or a lower height H as the end stop member 11 is narrower. have.

  In the short cylinder part 12, since a part of the material of the substrate part 11 is formed by a drawing method, the outer shape of the short cylinder part 12 is used in order to make the obtained short cylinder part 12 into a structurally stable shape. S3 has the 2nd characteristic that it has the taper surface diameter-reduced as it goes to the front-end | tip. However, the inner shape S2 has a tapered surface that is reduced in diameter as it goes to the tip in order to facilitate the die-cutting of the male part 5 during drawing, or both the inner and outer shapes S2 and S3 have a tapered surface, and The taper angle of the inner shape S2 is made steeper than that of the outer shape S3.

  Next, the end stop member 9 according to the present invention inevitably requires a predetermined space for holding the substrate portion 11 around the proximal end of the short cylindrical portion 12 with a mold in the molding method. The third feature is that the outer shape S1 of the portion 11 is significantly larger than the outer shape S3 of the short cylindrical portion 12. In the present invention, since the outer shapes of the substrate portion 11 and the short cylinder portion 12 are not constant, the outer shape S1, the outer shape S2, and the outer shape S3 are assumed to have various outer shapes corresponding to circles, and the outer area Is the size calculated by substituting for the area of the virtual circle.

  Furthermore, since the lower male part 4 forcibly penetrates the board part 11 from the back surface side in the manufacturing process, the end stopper member 9 according to the present invention has the board part 11 and the short cylinder part 12. It has a fourth feature that it communicates.

(Precursor for end stopper)
The end stop member according to the present invention is manufactured by the method as described above, and the obtained end stop member has the above-described characteristics. When such an end stop member is used, the through hole of the member layer is used. In order to achieve the ultimate purpose of facilitating positioning with respect to the member, in the present invention, the precursor for the end-stop member just before forming the end-stop member having the above-mentioned shape / structure is subjected to the caulking process of the member layer. Used in.

  That is, as shown in FIGS. 5 to 7, a plurality of constricted portions 10 are formed at predetermined intervals on a tape or sheet-like substrate 1 made of a plastic synthetic resin having a predetermined thickness T, and A plurality of end-stop members 9a, 9b, 9c, which are formed by drawing the substantially central portion C of the plurality of substrate portions 11 other than the constricted portion 10 to form the short cylindrical portion 12 vertically. A precursor 13 for 9d (in the present specification, a typical reference numeral 9 may be used for the plurality of end-stop members) is used.

  Here, the constricted portion 10 refers to a narrow connecting portion of the base material 1 having a function of connecting the plurality of end stopper members 9a, 9b, 9c, 9d,. Meaning, since it is a part of the base material 1 that is broken in the stage of forming the end stop member 9 to be described later, the size and shape of the base stop member 9 are connected to a plurality of end stop members 9a, 9b, 9c, 9d,. What is necessary is just to satisfy | fill the cutting | disconnection of the base material 1 simultaneously. Moreover, although the shape of the board | substrate part 11 is as above-mentioned, as shown in FIG. 8, the outer edge part can be trimmed and it can also decorate like a petal.

(Precursor production method)
Next, the precursor 13 for the end stopper 9 having the shape and structure as described above is manufactured through the following steps. That is, as shown in FIGS. 9 to 12, a first step of preparing a tape or sheet-like base material 1 made of plastic synthetic resin having a predetermined thickness T, and the base material 1 as a pair of upper and lower molds 3, 4 and a second cutting blade 8 projecting downward from the upper mold 3 to partially cut the substrate 1 to form a constricted portion 10 as shown in FIG. The second step and drawing the non-constricted portion where the constricted portion 10 does not exist, and vertically form the short cylindrical portion 12 whose diameter is reduced as the outer peripheral surface reaches the tip as shown in FIG. The precursor 13 is formed by a method including the fourth step.

  Further explanation will be given. Preferably, in the base material 1, as shown in FIG. 9, the induction through holes 12 for inducing the end face formation of the short cylindrical portion 12 at the time of drawing are formed at a predetermined interval in the longitudinal direction. It is transparent in the center in the direction. The upper die 3 is formed with a concave female portion 6, and the lower die 4 is formed with a male portion 5 that fits into the female portion 6. Instead of providing the induction through hole 12 in the base material 1, the first cutting blade 7 for forming the end surface of the short cylinder part 12 on the ceiling of the female part 6 may be provided.

  By repeating each of the above steps, the base material 1 has a plurality of substrate portions 11 as non-constricted portions between the plurality of constricted portions 10 as shown in FIG. It is possible to obtain a precursor 13 having a shape and structure in which a plurality of end stopper members 9 each consisting of a short cylindrical portion 12 rising vertically from the constricted portion 10 are connected. It is not necessary to perform the four steps in that order, and the second step can be performed simultaneously with the fourth step between the upper and lower molds 3 and 4 after the third step. In short, those steps may be performed in the order in which the above-described precursor 13 according to the present invention can be obtained.

(Method for simultaneously forming end stopper members and caulking member layers)
Next, how to separate and shape the end stopper 9 from the precursor 13 having such a shape and structure will be described. As shown in FIGS. 5 and 6, first, a precursor 13 in which a plurality of end stoppers 9 are connected via a constricted portion 10 is prepared. That is, a first step of providing a plurality of constricted portions 10 with a predetermined interval on a plastic synthetic resin tape or sheet-like substrate 1 having a predetermined thickness T, and a non-constricted portion other than the constricted portions 10 The precursor 13 for the end stop member 9 is prepared through a second step of forming the short cylinder portion 12 by drawing the substantially central portion of the plurality of substrate portions 11.

  Next, as shown in FIG. 13, at least the first plate-like member 21 and / or the second plate-like member 22 are prepared, and the through-hole 24 is provided in the member layer 29 made of the laminate (third step). . When the precursor 13 and the member layer 29 are thus prepared, the member layer 29 and the precursor 13 are interposed between the upper mold 3 and the lower mold 4 as shown in FIG. The upper mold 3 is configured such that when the truncated conical core portion 30 that can be inserted into the distal end opening 12a of the short cylindrical portion 12 of the precursor 13 and the distal end opening 12a abut, the distal end portion 12b faces outward. And a contact surface 33 that performs a function of expanding and crushing downward. Further, a third cutting blade 35 is attached downward to the upper mold 3 at a position away from the core portion 30 by a predetermined distance, and the constricted portion 10 of the precursor 13 can be cut off in the next step. ing. Thus, the short cylindrical portion 12 is inserted from the one surface side of the member layer 29 so as to face the through hole 24, and the tip portion protrudes to the other surface side (fourth step).

  Next, as shown in FIG. 15, when the upper and lower molds 3 and 4 are moved relatively close to each other, the abutting surface 33 abuts the tip opening 12a, and then the tip 12b is expanded outward and downward. When crushed, the third cutting blade 35 breaks the constricted portion 10 of the precursor 13 (fifth and sixth steps). Then, as shown in FIG. 16, the precursor 13 is separated and independently formed to form the end stop member 9 and simultaneously the caulking of the member layer 29 occurs. In the present invention, the extent to which the distal end flange 34 formed by the distal end portion 12b expanding outward and being crushed downward is within a range where the outer peripheral edge of the distal end is not ruptured.

  As shown in FIGS. 16 and 17, the end stop member 9 incorporated in the member layer 29 in this way is different from a conventionally known end stop member in that the thickness D of the base end portion 11 is the thickness of the short cylindrical portion 12. In addition to being larger than D1, the outer shape S1 of the base end portion 11 is very large compared to the outer shape S4 of the distal end flange 34. Therefore, it is denied that the end fastening member 9 according to the present invention has a lower caulking force for fastening the member layer 29 than that of the known metal end stop member or the above-described known resin end stop member. However, the effect of reliably protecting the end face in the through hole 24 of the member layer 29 is significantly superior to that of the conventional end stopper member.

  In other words, since the outer shape S1 of the substrate portion 11 is large, the end stopper member 9 according to the present invention exhibits an effect that it is perfectly aligned so as to stick to the member layer 29 on one side, unlike that of the prior art. And the short cylinder part 12 which stands | starts up vertically from that is controlled by the board | substrate part 11, and becomes independent, and protects the through-hole 24 inner surface.

(Application example of the present invention)
Finally, an article wrapping medium will be described as an application example that effectively exhibits the function of the end stopper member having such a shape and structure. As shown in FIG. 18, an article to be packaged in the bulging portion 23 of the first plate-like member 21, that is, an article 20 to be packaged is put, and as shown in FIG. Slide members 25a, 25b, 25c (sliding members) formed by bending the three side edges of the second plate member 22 to the three side edges of the first plate member 21 while sliding the member 22. The locking portion 25c is not disclosed in FIG. 19, but is locked in (described later in FIG. 22 and FIG. 23), and as shown in FIG. By fastening the U-shaped nail 26 (the part located in the lower part in FIG. 20), the packaged article 20 is packaged by the first plate-like member 21 and the second plate-like member 22, and the packaged article 20 is tampered with. Is preventing.

  On the other hand, the heads of both the members 21 and 22 are rectangular in shape, and a through hole 24 having a curved portion is provided in the middle of one side, and the through hole 24 is provided from a display wall 27 such as a store. By passing the extending cantilever support rod 25, the article to be packaged 20 is displayed. The end stop member 9 according to the present invention shown in FIG. 21 was used for the member layers 29 of the first and second plate-like members 21 and 22 for packaging the packaging medium 20, as shown in FIGS. In some cases, it exhibits unique actions and effects. This operation and effect will be described next.

  First, as shown in FIG. 21, the precursor 13 used in this embodiment includes a plurality of end-stop members 9 each having a substantially rectangular substrate portion 11 and a short cylindrical portion 12 having a substantially rectangular cross section. Are connected by the constricted portion 10. Further, an arc portion 14 is formed at the center of one of the two long sides of the precursor 13 where the short cylinder portion 12 is formed. As shown by 20, the cantilever support bar protrudes from the display wall 27 into the through-hole 24 formed in the heads of the first plate-like member 21 and the second plate-like member 22 that package the article to be packaged 20. 28 is positioned and locked.

  As shown in FIGS. 22 and 23, when the end-stop member 9 separated from the precursor 13 is caulked to the first plate member 21 and the second plate member 22, as shown in FIGS. In addition, the member layer 29 of the first plate member 21 and the second plate member 22 is guided to a predetermined position between the pair of upper and lower molds 3, 4. The short cylinder part 12 which is a component is positioned so that the inside of the through-hole 24 of the 1st plate-shaped member 21 and the 2nd plate-shaped member 22 may be faced.

  Next, when the upper and lower molds 3 and 4 are relatively moved up and down, as shown in FIG. 16, the precursor 13 and the member layer 29 approach each other, and the short cylinder portion 12 is placed in the through hole 24 of the laminated body 29. The third cutting blade 35 attached to the upper mold 3 breaks the constricted portion 10 of the precursor 13. At this time, the tip portion 12b of the short cylindrical portion 12 rising from the core portion 30 facing the through hole 24 of the member layer 29 is expanded outward and is relatively crushed downward. .

  As a result, as shown in FIG. 16, the substrate portion 11 in the precursor 13 functions as a proximal end flange of the short cylindrical portion 12 rising from its substantially center, and the distal end portion of the short cylindrical portion 12 functions as a distal end flange 34. In addition to constituting the end stop member 9, the inner surface of the short cylindrical portion 12 and the upper surface of the tip flange 34 have shapes similar to the through holes 24 of the member layer 29 as shown in FIG. 24. It reaches.

  Moreover, in the end stopper member 9 according to the present invention, due to the manufacturing method, first, the outer shape S1 of the substrate portion 11 is significantly larger than the outer shape S4 of the tip flange portion 34 (see FIG. 16, hereinafter). the same). Next, due to the plastic press molding method of the plastic synthetic resin, which is the main process of the manufacturing method, the thickness of the short cylindrical portion 12 and the tip flange 34 becomes very thin compared to the thickness D of the substrate portion 11. Furthermore, due to the same molding method, the height H of the short tube portion 12 is very small compared to that of the prior art. In the present invention, the height H of the short cylinder portion 12 is in the range of ~ times the thickness D of the substrate portion 11. The thickness of the distal end flange 34 is a taper shape that becomes thinner as the short cylindrical portion 12 itself approaches the distal end, and therefore, at least the thickness D1 of the proximal end portion (the portion indicated by reference numeral P1) of the short cylindrical portion 12. It means a thinner thickness.

  As described above, the present invention has a resin end stopper member and its shape and structure that are remarkably different from those of known ones. Therefore, the end stopper member according to the present invention has a plurality of plate-like members. It can be said that it is excellent in the function which protects or decorates the inner peripheral end surface of the through-hole formed in the member layer rather than the function to join to. Conventionally, the first plate-like member 21 and the second plate-like member 22 are fastened with U-shaped metal nails at their bottoms to prevent tampering of the packaged article 20 (see FIG. 20). In this embodiment, since the through-hole 24 in the head is crimped by the end stop member 9, it is not necessary to use such a metal nail. Therefore, when discarding the 1st, 2nd plate-shaped members 21 and 22, this invention exhibits the additional effect that there is no environmental problem.

  The present invention follows the fundamental technical idea, and it is naturally allowed to change and implement a part of the above-described embodiment as long as the effects of the invention are not significantly impaired. For example, as shown in FIGS. 25 and 25, the first plate-like member 21 and the second plate-like member 22 have first through holes 24 that are two-dimensionally connected to the outer edges 31 of the members 21 and 22. A member having a shape in which the outer portion of the through hole 24 in the plate member 21 and the second plate member 22 is broken can be used. If such embodiment is employ | adopted, the effect of this invention will be retroactive to the process of manufacturing the 1st, 2nd plate-shaped members 21 and 22. FIG.

  This is because when the first plate-like member 21 and the second plate-like member 22 having the through holes 24 are manufactured, the outer shape of the first plate-like member 21 and the second plate-like member 22 is larger as shown in FIG. The first plate member 21 and the second plate member 22 are cut out from the original plate 32 using the original plate 32. At this time, if the through hole 24 is connected to the outer edge 31 two-dimensionally. When the first plate member 21 and the second plate member 22 are formed, chips generated when the through holes 24 are cut out are attached to the remaining portion of the original plate 32. This is because the operation of separately pulling out the through holes 24 from the member 21 and the second plate-like member 22 is not necessary.

  In the present invention, as shown in FIG. 20, the end stopper member 9 according to the present invention also has an inner peripheral end face of the through hole 24, even in a mode in which the through hole 24 is two-dimensionally connected to the outer edge 31. Therefore, the article to be packaged 20 and the like can be supported by the cantilever support rod 28 extending from the display wall 27.

  As a method of forming the inner peripheral end face structure of the through hole according to the present invention, by devising a pair of upper and lower molds, the plastic synthetic resin tape and the first plate member and the second plate member are overlapped, By pressing simultaneously, a through-hole can be formed in the member layer with the first plate-like member and the second plate-like member, and the short tube portion can be inserted into the through-hole.

  Moreover, in order to strengthen or decorate the inner peripheral end surface of the through-hole, using only a 1st plate-like member depending on a use, without using a 1st plate-like member and a 2nd plate-like member for a member layer. The technique according to the present invention can be employed. In this aspect, that is, in the end stopper member formed by inserting the short tube portion of the synthetic resin end stop member into the through hole of the member layer and caulking, the tip flange portion at the tip portion of the short tube portion is based on the base member. An inner peripheral end face forming structure that is smaller and thinner than the proximal flange portion at the end is realized in the member layer.
