Description

Technical Field

[0001] The present invention relates to a method for processing a caulking button member, a caulking button member to which the processing method is applied, and a caulking button member processing jig used for processing the caulking button member, which enables easy and quick alignment when caulking is performed.

Background Art

[0002] Conventionally, resin hooks (also called plastic snaps, and hooks are also called snap fasteners) are known. For example, as disclosed in Patent Document 1, a resin hook has a rivet member and a fitting member, and each of them has a structure in which the fabric is sandwiched from the front and back surfaces and integrated. The rivet member has a protrusion, and the fitting member has a through hole corresponding to the protrusion. Then, after the protrusion penetrates the fabric, the through hole of the fitting member is inserted, and the tip portion is expanded and deformed to perform caulking. By doing so, the rivet member and the fitting member are integrated to obtain a resin hook.

[0003] On the other hand, conventionally, decorations such as characters, figures, and patterns may be formed on members (hereinafter referred to as "caulking button members" in the present invention) that are caulked (crimped) and attached to the fabric, such as resin hooks, snap buttons, push buttons, jeans buttons, and eyelets. For example, Patent Documents 2 and 3 disclose that characters and patterns are applied to the surface of buttons using an inkjet printer.

[0005] As mentioned above, the resin fastener has a rivet member and a mating member, which are positioned on the front and back surfaces of the fabric, and are attached to the fabric by being crimped together.

[0006] Furthermore, these rivet components may have decorations including letters, figures, symbols, or patterns formed on them. In such cases, they are also crimped together to form a single unit and then attached to the fabric. At that time, it is important that the resin fasteners are attached to a designated position on the fabric (for example, the edge of the seam between the left and right sides of the front of the garment) and facing in a designated direction (so that the formed letters, figures, symbols, or patterns are facing the correct direction and are clearly visible).

[0007] However, when riveting is performed, a specific tool is required, and the rivet member must be set on that tool so that the projection faces upwards. As a result, when the rivet member is set, any decorations including letters, figures, symbols, or patterns are on the underside of the rivet member's head, making them impossible to directly see during riveting. Therefore, when the rivet member is set on the tool, the decorations including letters, figures, symbols, or patterns are likely to be oriented incorrectly. To prevent this, it is necessary to hold the projection and directly see the letters, figures, symbols, or patterns to confirm that the head is facing the correct direction, and this extra step hinders efficient attachment to the fabric. Similar problems exist with snap buttons and push buttons, and the same problem also exists with jeans buttons and eyelets that have a button body with a head and a cylindrical receiver, and a rivet body that can be fitted into the cylindrical receiver.

[0008] The present invention has been made to solve the above problems, and aims to provide a method for processing a crimp button member so that the direction alignment during crimping can be easily and quickly performed, a crimp button member to which this processing method is applied, and a processing jig for a crimp button member used for processing the crimp button member. [Means for solving the problem]

[0009] To solve the above problems, the present invention provides a method for processing a rivet member having a head formed in the shape of a generally circular or polygonal plate, comprising a direction indicator forming step in which, when a decoration including characters, figures, symbols or patterns is formed on the surface of the head using ink droplets ejected from the print head of an inkjet printing device, the ink droplets wrap around to the back side of the head, thereby forming a direction indicator that is effective in specifying the direction of the decoration formed on the surface of the head.

[0010] In the above-described method for processing the crimped button member, the step of forming the direction indicator portion uses a processing jig having a locking recess corresponding to the head of the rivet member. The processing jig has a depth that exposes a part of the peripheral end on the back side of the head that is locked in the locking recess, and an extended recess is formed that extends outward from the peripheral edge of the locking recess, so that ink droplets can be applied to the extended recess so that the ink droplets wrap around to the back side of the head.

[0011] Furthermore, the present invention provides a crimp button member having a head that is generally circular or polygonal in shape, wherein a decoration including characters, figures, symbols, or patterns is formed on the surface of the head using ink droplets ejected from the print head of an inkjet printing device, and a direction indicator is formed on the head that is effective in identifying the direction of the decoration formed on the surface of the head as the ink droplets wrap around to the back side of the head.

[0012] Furthermore, the present invention provides a processing jig for processing crimp button members having a head formed in a generally circular or polygonal plate shape, wherein the jig has a locking recess corresponding to the head of the crimp button member, and has an extended recess that extends outward from the peripheral edge of the back side of the head when the head is locked in the locking recess, and has a depth such that a part of the circumferential end on the back side of the head is exposed, and extends outward from the peripheral edge of the locking recess. [Effects of the Invention]

[0013] As described in detail above, the present invention provides a method for processing a crimp button member so that the direction alignment during crimping can be easily and quickly performed, a crimp button member to which this processing method is applied, and a processing jig for a crimp button member used for processing the crimp button member.

Embodiment for Carrying out the Invention

[0015] Regarding the caulking button member according to the embodiment of the present invention, taking the rivet member 1 as an example, it will be described with reference to FIGS. 1 to 6. FIGS. 1 to 5 are diagrams showing the rivet member 1 according to the embodiment of the present invention. FIG. 1 is a perspective view, FIG. 2 is a plan view, and FIG. 3 is a front view. FIG. 4 is a rear view, and FIG. 5 is a sectional view taken along line 5-5 of FIG. 4. FIG. 6 is an exploded perspective view showing the attachment procedure to the fabric 6 using two rivet members 1 and the fitting member 10.

[0016] The rivet member 1 is a resin member formed using a synthetic resin such as nylon resin or acrylic resin. The rivet member 1 has a head 2 and a caulking projection 3, and both are integrally formed. In the case of the illustrated rivet member 1, the head 2 and the caulking projection 3 are resin members, but the head 2 may be a resin member and the caulking projection 3 may be a metal member, or both the head 2 and the caulking projection 3 may be metal members.

[0017] As shown in FIG. 2, the head 2 is formed in a generally circular plate shape in plan view. As shown in detail in FIGS. 3 and 4, the head 2 has a front surface 2b and a rear surface 2d, and has an annular edge portion 2c formed along the peripheral edge of the front surface 2b.

[0018] As shown in Figure 3, the surface 2b is formed in a slightly dome shape with its center 2a as the apex (other shapes are also possible, but will be explained in detail later). As shown in Figures 1 and 2, a spider-shaped decoration 4 is formed on the surface 2b. The decoration 4 is formed on the surface 2b by an inkjet printing process, which will be explained later. As shown in Figure 5, the annular edge 2c extends from the surface 2b to the back surface 2d. A crimping projection 3 is erected in the center of the back surface 2d. The illustrated decoration 4 includes a spider-shaped figure, but it can also include letters such as the alphabet, or figures, symbols, or patterns other than spiders.

[0019] A directional indicator section 5 is formed on the head 2. As shown in Figures 4 and 5, the directional indicator section 5 is formed on the circumferential end of the back side of the head 2, that is, on the end 2cc on the back side 2d of the annular edge 2c (as shown in Figure 4, the end 2cc is formed in a narrow annular shape), and further extends from there to the inner surface 2ca and even to the back side 2d. The illustrated directional indicator section 5 is formed at a location on the lower side when viewed from above (as shown in Figure 2, in the direction in which the spider figure can be correctly seen). Since the directional indicator section 5 extends from the end 2cc to the back side 2d and can be directly seen from the back side 2d, it can be used as a directional mark. A directional mark is an effective mark for identifying the direction of the decoration 4 on the back side (the direction in which the formed figure, letters, and symbols are facing the correct direction and can be correctly seen) when the rivet member 1 is set in a crimping tool (not shown) and the back side 2d is visible.

[0020] As shown in Figures 1, 3, and 4, the crimping projection 3 has a sharp tip 3a, a pointed tip 3b that gradually increases in thickness from the tip 3a toward the back surface 2d, and a base 3c that is of roughly uniform thickness and connected to the back surface 2d.

[0021] Furthermore, the processing method according to the present invention is applied to the rivet member 1, thereby enabling easy and quick alignment of the direction when crimping is performed, as described later. In this processing method, the decoration 4 is formed on the surface 2b of the head 2, and when the decoration 4 is formed, the direction indicator part formation step described later is performed, thereby forming the aforementioned direction indicator part 5.

[0022] (Processing method) The processing method according to the present invention uses a processing jig 30 and an inkjet printing device 50. The processing jig 30 is a plate-shaped member made of resin, metal, etc., and is formed in a rectangular plate shape in plan view as shown in Figure 7. Multiple mounting parts 35 are arranged regularly in the vertical and horizontal directions on its surface 30a.

[0023] Each mounting portion 35 has a locking recess 31, a through hole 32, and an extended recess 33 formed in connection with a part of the locking recess 31. A rivet member 1 is mounted on each mounting portion 35 as shown in Figures 8 and 9.

[0024] The locking recess 31 is a recess formed on the surface 30a of the processing jig 30. The locking recess 31 is a circular recess in plan view, sized to correspond to the head 2 of the rivet member 1, and its depth is smaller (shallower) than the height of the annular edge 2c. As shown in Figure 9, the locking recess 31 has a circular band-shaped bottom 31d in plan view, and when the rivet member 1 is placed on the mounting portion 35, the annular edge 2c is locked by its bottom 31d.

[0025] The through-hole 32 is a through-hole (extending from the surface 30a to the back surface 30b of the processing jig 30) formed approximately in the center of the inside of the locking recess 31, and is formed to be larger in size than the diameter of the crimping projection 3.

[0026] As shown in Figures 8 and 9, the extended recess 33 is a recess formed to wrap around from the outside to the inside of the locking recess 31. The extended recess 33 has a depth greater than that of the locking recess 31, that is, a depth to which the back side peripheral end (the end 2cc on the back side 2d of the annular edge 2c) of the head 2 that is locked to the locking recess 31 is exposed. Because the extended recess 33 has a greater depth than the locking recess 31, when the head 2 is locked to the locking recess 31 as shown in Figures 8 and 9, the portion of the end 2cc that is positioned on the extended recess 33 is exposed without coming into contact with the locking recess 31.

[0027] The extended recess 33 has an overhanging recess 33a and an inner recess 33b. The overhanging recess 33a is a recess formed on the surface 30a so as to protrude outward from the peripheral edge 31a of the locking recess 31. The inner recess 33b is a recess formed so as to wrap around from the overhanging recess 33a to the inside of the peripheral edge 31a.

[0028] A rivet member 1 is placed on each mounting section 35. At this time, the crimping projection 3 is inserted through the through hole 32, and the annular edge 2c is locked to the bottom 31d. Since multiple mounting sections 35 are arranged on the processing jig 30, the printing process using the inkjet printing device 50 is performed with multiple rivet members 1 arranged on the processing jig 30. At that time, the direction indicator section formation step is performed.

[0029] As shown in Figure 10, the inkjet printer 50 has a print head 51. The print head 51 has four nozzles 52. In this embodiment, each nozzle 52 is connected to an ink container (not shown) of cyan, magenta, yellow, and black (other colors are also possible, and the number of nozzles 52 is not limited to four). Each nozzle 52 ejects an ink droplet of the respective color.

[0030] Then, in the printing process using the inkjet printing device 50, ink droplets id are applied to each mounting section 35 by moving the print head 51 of the inkjet printing device 50 in the direction of arrow X over the processing jig 30 on which multiple rivet members 1 are arranged. At that time, ink droplets id of a color corresponding to the image data output from a control device (not shown) are applied to the surface 2b of each rivet member 1. This forms the decoration 4 described above.

[0031] In the printing process, a direction indicator formation step is performed. In the direction indicator formation step, at each mounting section 35, a certain amount of ink droplet id ejected from the print head 51 is applied to the extended recess 33 so that the ink droplet id wraps around to the back surface 2d side of the head 2. As the extended recess 33 has a depth greater than that of the locking recess 31, which is the depth to which the end portion 2cc is exposed, the ink droplet id to be applied is applied to the end portion 2cc exposed in the extended recess 33. Furthermore, since the extended recess 33 has an inner recess 33b and is formed to wrap around to the inside of the peripheral edge 31a, the ink droplet id can also wrap around to the inside of the peripheral edge 31a of the locking recess 31, and wrap further around from the end portion 2cc to the inner surface 2ca and even the back surface 2d, so that the ink droplet id can be applied to them.

[0032] In this way, the direction indicator section 5 is formed. At this time, it is advisable to adjust the amount of ink droplet id applied to the extended recess 33. For example, if the amount of ink droplet id applied is reduced, the direction indicator section 5 will be formed only on the end portion 2cc, or it is possible to form the direction indicator section 5 only on the end portion 2cc and the inner surface 2ca. In either case, because the extended recess 33 is formed on each mounting portion 35, the ink droplet id is applied to the end portion 2cc, the inner surface 2ca, and the back surface 2d, thereby forming a direction indicator section 5 that can be used as a direction mark.

[0033] On the other hand, as shown in Figure 6, the rivet member 1, together with the mating member 10 (female mating member 10A, male mating member 10B), is positioned to sandwich the front and back sides of the fabric 6, respectively, and is attached to the fabric 6. The mating member 10 is made of synthetic resin (it may also be made of metal), and together with the female mating member 10A and the male mating member 10B, it has a through hole 10d through which the crimping projection 3 passes.

[0034] Then, the rivet member 1 is placed on a crimping tool (not shown) with the crimping projection 3 facing upward (at this time, the surface 2b of the head 2 is located on the back side of the back surface 2d, so it cannot be seen with the naked eye), and the material 6 is placed on top of it (so that the mounting location is positioned on the crimping tool). Furthermore, the female mating member 10A or the male mating member 10B is placed on top, and then the crimping tool is operated to perform crimping. As a result, the tip 3a of the crimping projection 3 is crushed and deformed in diameter, preventing it from coming out of the through hole 10d, and thereby the rivet member 1, 1 and the female mating member 10A or the male mating member 10B are integrated and the attachment to the material 6 is completed.

[0035] As described above, when attaching the hook, the surface 2b of the head 2 is positioned on the back side of the back surface 2d, so the surface 2b cannot be directly seen. Consequently, the rivet member 1 is likely to be facing in an inappropriate direction when set in the crimping tool.

[0036] However, the rivet member 1 has a direction indicator 5 formed on it, which is formed by ink droplets id that have passed through the extended recess 33 of the processing jig 30 and wrapped around from the surface 2b to the back surface 2d. Therefore, the direction indicator 5 can be directly seen from the back surface 2d. For this reason, the direction indicator 5 is used as a direction mark. Thus, even when the rivet member 1 is set in the crimping tool, it is not necessary to directly see the surface 2b of the head 2 to check whether the head 2 is facing the correct direction. Instead, the direction of the head 2 can be identified and its correct orientation determined simply by looking at the direction indicator 5. Therefore, since the direction indicator 5 can be used as a guide to quickly determine that the rivet member 1 is placed in the correct direction, aligning the direction during crimping becomes simpler and faster, and thus efficient attachment to the material becomes possible.

[0037] Furthermore, one can determine how to position the rivet member 1 when setting it on the crimping tool, for example, by ensuring that the direction indicator section 5 is facing towards the front (bottom). Alternatively, one can determine how to set the rivet member 1 on the crimping tool by forming a mark on the crimping tool and aligning the direction indicator section 5 with that mark. In this way, efficient attachment of the rivet member 1 and the mating member 10 to the base material 6 becomes possible.

[0038] The aforementioned head 2 was formed in a dome shape. Instead of head 2, as shown in Figure 11(a), a head 2A can be made, which has a shallow, mortar-shaped surface with a slight indentation in the center so that the center becomes the bottom. Alternatively, as shown in Figure 11(b), a head 2B can be made, which has a flat surface, or the surface may have irregularities. Furthermore, although head 2 was formed in a generally circular plate shape in plan view, it may also be formed in a polygonal plate shape such as a hexagon or octagon in plan view (not shown). The crimping projection 3 had a sharp tip 3a, but it may also be formed in a cylindrical shape with a generally uniform diameter, or a cylindrical shape that gradually decreases in diameter towards the tip.

[0039] Although not shown in the illustrations, the present invention can be applied to components that are attached to fabric by crimping, such as resin hooks, snap buttons, push buttons, jeans buttons, and eyelets. [Industrial applicability]

[0040] By applying the present invention, directional alignment during crimping can be performed easily and quickly. The present invention can be used in the fields of a method for processing crimp button members, crimp button members to which the processing method is applied, and processing jigs for crimp button members used in processing crimp button members.
