Description

Button mounting device

Technical field

The present invention relates to a button attachment device, and in particular to a button attachment device that holds one side of a fixing member when attaching a button body to a material such as clothing using the fixing member.

Background technique

When attaching the button body to the blank, generally, after holding the button body on the upper mold and placing the fixing member on the lower mold, the upper mold is lowered toward the lower mold. Thereby, the post of the fixing member penetrates the blank upward, and then, after the post passes through the opening for attachment of the button body, riveting is performed using the punch of the upper mold. Thereby, the button main body is fixed to the blank. The blank is compressed between the button body and the fixing member, and friction generated by the reaction force of the compression prevents the fixing member and the button body from rotating. However, for example, if the material is thin, the reaction force and friction mentioned above are insufficient, and the attached button body may rotate and fall off easily. Under such circumstances, conventionally, an intermediate member called a spacer was sandwiched between the fixing member and the blank to compensate for the lack of thickness of the blank. In addition, for the purpose of improving the design of clothes or the like, a pad whose outer diameter is larger than the outer diameter of the button body may be inserted.

Japanese Patent No. 6239952 (Patent Document 1) discloses a technology in which an upper mold and a lower mold are used to attach a button body to a blank using a fixing member. A lining band with a cutout is formed on the outer periphery of the lining so that the lining is sandwiched between the fixing member and the blank. However, in the technology of Patent Document 1, when the lining tape is made of a soft material such as felt, the fibers are not broken when the lining tape is punched out with a punch, and defects tend to occur. In addition, it is not easy to accurately align the center of the cutout of the liner tape with the center of the fixing member held by the lower mold, and the center of the liner and the center of the fixing member tend to deviate.

Therefore, an object of the present invention is to provide a button attachment device in which punching defects are unlikely to occur even if the pad tape is made of soft material such as felt, and the center of the pad and the center of the fixing member will not deviate.

solutions to problems

In order to solve the above problem, according to the present invention, there is provided a button attachment device that holds one side of the fixing member together with the button body, the fixing member, and the pad when the button body is attached to the blank, and is characterized in that , the button mounting device is provided with: a moving member for moving the fixing member from an initial position to an installation position; and a passage for moving the fixing member between the initial position and the installation position. The path intersects for the liner tape to pass; and a cutting part is used to cut the liner tape at the intersection of the moving path and the belt passage to form the liner, and the cutting part includes a cutter from the The first surface and the second surface of the lining tape penetrate the first cutting part of the lining tape.

When attaching the button body to a material such as clothing, the moving member moves the fixing member from the initial position to the installation position, so that part of the fixing member (posts, etc.) penetrates the material, and the posts, etc. of the fixing member are held relative to the installation position. The button body of the upper mold is riveted, thereby fixing the button body to the blank. In the present invention, a belt passage for the lining tape to pass is provided so as to intersect with the movement path between the initial position and the installation position of the fixing member, and the lining tape is cut by the cutting portion at the intersection of the movement path and the belt passage. Cut it out as a liner. The cut liner is transported to the installation position together with the fixed member by the moving member, where it is sandwiched between the blank and the fixed member. In the present invention, the cutting portion includes a first cutting portion that penetrates the lining tape from the first surface to the second surface. Therefore, the lining tape can be cut at once without forming a cut or the like in the lining tape in advance. , even if the lining tape is made of soft material such as felt, it is possible to obtain a beautiful lining with a cut outer circumference. In addition, the cutting position of the liner cut out from the liner tape is set to the intersection of the moving path of the fixing member and the belt passage. Therefore, the liner cut out from the liner tape and the fixing member are automatically arranged concentrically, and the liner is The center will not deviate from the center of the fixed component.

In the present invention, the padding tape is a vertically elongated strip for cutting out a plurality of pads. Examples of raw materials for the padding tape include non-woven fabrics such as felt, synthetic fibers such as nylon and polyester, and leather. But it is not limited to these. In addition, the fixing member may be made of metal such as aluminum alloy or copper alloy, or may be formed of thermoplastic resin, thermosetting resin, or the like.

In one embodiment of the present invention, the cutting part includes a second cutting part, the second cutting part supports the second surface of the lining tape, and has a structure capable of receiving the lining tape that has penetrated the lining tape. the opening of the first cutting part. In this form, when the first cutting part penetrates the lining tape from the first surface to the second surface, the second cutting part supports the lining tape from the second surface and receives the first cutting part that has penetrated the lining tape in the opening. department. At this time, the cutting edge (second cutting edge) between the surface of the second cutting part facing the second surface of the liner tape and the peripheral surface defining the opening is used in cutting of the lining tape by the first cutting part. At the same time, it acts on the liner tape to promote cutting.

In one embodiment of the present invention, the second cutting part has a second cutting edge between a surface facing the lining tape and a peripheral surface defining the opening, and the second cutting edge is formed along The position of the cutting edge in the direction of the axis of the opening changes. In this form, the position of the second cutting edge in the direction along the axis of the opening, that is, in the axial direction, is not constant but changes. In this case, the timing at which the second cutting edge of the second cutting part acts on the liner tape is shifted, so that the liner tape can be cut gradually. Therefore, compared with the case where the entire second cutting edge acts on the liner tape at the same time, the load required for cutting the liner tape can be reduced. For example, in the circular second cutting edge, the two cutting edge positions of the first group that are spaced 180 degrees apart from each other are located in the axial direction closest to the lining tape side of the belt passage, and are different from the cutting edge positions of the first group. The two cutting edge positions of the second group separated by 90 degrees are located at the farthest position from the liner tape, and can be set in such a way that the cutting edge position gradually changes from the cutting edge position of the first group to the cutting edge position of the second group. Certainly. Alternatively, the position of the cutting edge may be changed so that the circular second cutting edge becomes wavy in one direction and then in the other direction in the axial direction, along the outer periphery of the circle.

In one embodiment of the present invention, the first cutting part moves together with the moving member until it penetrates the lining tape.

Effect of invention

In the present invention, the cutting portion includes a first cutting portion that penetrates the lining tape from the first surface to the second surface. Therefore, the lining tape can be cut at once without forming a cut or the like in the lining tape in advance. , even if the lining tape is made of soft material such as felt, it is possible to obtain a beautiful lining with a cut outer circumference. In addition, the cutting position of the liner cut out from the liner tape is set to the intersection of the moving path of the fixing member and the belt passage. Therefore, the liner cut out from the liner tape and the fixing member are automatically arranged concentrically, and the liner is The center will not deviate from the center of the fixed component.

The button base 10a includes a disc-shaped base 11a and a substantially annular engaged portion 12a protruding upward from the base 11a. The spring 14 is accommodated in the engaged portion 12a. An opening 13a is provided in the center of the base 11a. The button base 10a is also fixed to the blank f together with the fixing member 20 and the pad 30 like the button post 10 mentioned above. In addition, as can be seen from FIGS. 2 and 4 , in this example, the pad 30 is larger than the base 21 of the fixed member 20 , but it may be substantially the same size as the base 21 or may be larger than the base 21 . 21 small.

FIG. 5 is a perspective view of the button attachment device (lower mold) 100 according to the first embodiment of the present invention, in which the upper mold 200 and the conveyance mechanism 300 of the fixing member 20 are shown with dotted lines. Hereinafter, the button main body (10, 10a) attached to the blank f (see FIG. 1 etc.) using the button attaching device 100 or the like will be described as the button main body 10. However, the button main body 10a or other button main bodies are essentially the same. In FIG. 5 , the button attachment device 100 is shown in a state of being housed in a rectangular parallelepiped-shaped housing 101 . The housing 101 has a rear wall 102, a left side wall 103, a right side wall 104, and an upper wall 105, and most of the front portion opposite to the rear wall 102 is open. The upper wall 105 of the housing 101 has an opening 105a, and the upper portion of the button mounting device 100 is exposed to the outside of the housing 101 from the opening 105a. The upper mold 200 is arranged above the button mounting device 100 . The conveying mechanism 300 is arranged on the rear wall 102 side of the housing 101 . When attaching the button body 10 to the blank f, the fixing members 20 are automatically conveyed and supplied to the button attaching device 100 one by one by the conveying mechanism 300 . Thereby, the fixing member 20 is held in the holding part S (refer to FIG. 7) of the button attachment device 100 which will be discussed later. In addition, the button body 10 is automatically supplied and held by the upper mold 200 by a button body conveying mechanism (not shown). The fixing member 20 and the button main body 10 can also be held by the button mounting device 100 and the upper mold 200 manually, respectively.

FIG. 6 is a cross-sectional view of the button mounting device 100 along line A-A of FIG. 5 . The button attachment device 100 is provided with: a cylindrical moving member 110 for moving the fixing member 20 from an initial position to an attachment position; an annular member 120 arranged to surround the moving member 110; and a receiver 130 that essentially The upper part accommodates most of the moving member 110 and the annular member 120; a belt passage 140 through which the liner tape PT passes; and a cutting part 150 for cutting the liner tape PT to obtain the liner 30. In FIG. 6 , the fixed member 20 , the moving member 110 , the annular member 120 and the plunger 160 are located at the initial position which is the lowest point. Hereinafter, the state in which the fixing member 20 and the like are at the initial position will also be referred to as the "initial state".

The moving member 110 includes a solid cylindrical upper part 111 and a hollow cylindrical lower part 112 . The lower end of the lower part 112 of the moving member 110 is connected to the plunger 160 (only the upper end of the plunger 160 is shown in the figure), and the moving member 110 can be installed at the initial position (see FIG. 6 ) as the uppermost point by the plunger 160 . It moves back and forth along the movement path in the up and down direction between positions (see Figure 10).

The annular member 120 includes a thick-walled portion 121 having the largest outer diameter, a cylindrical first cutting portion 151 protruding upward from the thick-walled portion 121 , and a lower inner cylindrical portion 122 and a lower outer cylindrical portion 123 . Extends downward from the thick portion 121 . The thick portion 121 , the first cutting portion 151 and the lower inner cylindrical portion 122 have the same inner diameter, and the inner diameter is substantially the same as the outer diameter of the moving member 110 . In addition, the outer diameter of the thick-walled portion 121 is the same as that of the lower outer cylinder portion 123 , and the outer diameter is substantially the same as the inner diameter of the receiver 130 . The first cutting part 151 of the annular member 120 is also a component of the cutting part 150 and constitutes the cutting part 150 together with the second cutting part 152 to be discussed later. The first cutting portion 151 substantially has a constant inner diameter and an outer diameter, but is a thin-walled portion with a small thickness in the radial direction. The first cutting part 151 has a first cutting edge 151a at the upper end.

Long holes 113 that are long in the vertical direction are respectively provided on the opposite walls of the vertically intermediate portion of the lower portion 112 of the moving member 110 . The connecting shaft 114 passes through the two elongated holes 113 , and both ends of the connecting shaft 114 are connected to the lower inner cylinder 122 of the annular member 120 . Thereby, the moving member 110 is connected to the annular member 120 , and the annular member 120 can be linked together with the moving member 110 to a position where upward movement is limited by an upper wall 132 of the receiver 130 to be discussed later. In addition, one or more compression springs 115 as elastic members are arranged between the lower surface of the thick portion 121 of the annular member 120 and the upper end surface of the plunger 160 . The upper portion of the compression spring 115 is received between the lower inner cylinder portion 122 and the lower outer cylinder portion 123 of the annular member 120 . The compression spring 115 pushes the annular member 120 upward with respect to the moving member 110 until the connecting shaft 114 contacts the upper end of the elongated hole 113 .

In the initial state, the first cutting portion 151 of the annular member 120 protrudes upward from the upper surface 110 a so as to surround the upper surface 110 a of the moving member 110 . Thereby, in the initial state, a space S surrounded by the first cutting part 151 and open upward is generated on the upper surface 110 a of the moving member 110 . This space S is a holding portion S for receiving and holding the fixing member 20 supplied from the conveyance mechanism 300 . In the example of the fixing member 20 , the upper end of the column 22 of the fixing member 20 held by the holding part S is located slightly above the first cutting edge 151 a of the first cutting part 151 in the initial state.

The receiver 130 is a member that remains stationary relative to the moving member 110 and the annular member 120 that move up and down. The receiver 130 is provided with a peripheral side wall 131 and an upper wall 132, and is open downward. The outer shape of the peripheral side wall 131 is a shape obtained by chamfering four corners of a rectangular parallelepiped with a square horizontal cross section, as shown in FIG. 5 . Therefore, the peripheral side wall 131 has a front wall 131a, a rear wall 131b, a left side wall 131c, a right side wall 131d, and four corner portions 131e. The rear wall 131b of the receiver 130 is arranged on the transport mechanism 300 side. The upper wall 132 is provided with a circular first opening 133 in the center. The diameter of the first opening 133 is slightly larger than the outer diameter of the first cutting part 151 . The internal space of the peripheral side wall 131 is cylindrical, and the peripheral side wall 131 has a certain inner diameter. This inner diameter is substantially the same as the outer diameter of the annular member 120 . The upper wall 132 of the receiver 130 functions as a stopper that receives the thick portion 121 of the annular member 120 that moves upward and restricts the upward movement of the annular member 120 .

The cutting part 150 includes the above-mentioned first cutting part 151 and a plate-shaped second cutting part 152 provided upward with a slight gap from the upper wall 132 of the receiver 130 . A belt passage 140 is provided between the upper wall 132 of the receiver 130 and the second cutting part 152 . In other words, the upper surface of the upper wall 132 defines the lower surface of the belt passage 140 , and the lower surface of the second cutting portion 152 defines the upper surface of the belt passage 140 . An introduction portion 142 for introducing the pad tape PT into the tape passage 140 is provided at the upper end portion of the right side wall 131d of the receiver 130. In addition, a discharge portion 141 for discharging the pad tape PT after the pad 30 has been cut out from the tape passage 140 is provided at the upper end portion of the left side wall 131 c of the receiver 130 . The introduction portion 142 has an introduction surface 142 a that is inclined upward toward the downstream side of the belt passage 140 , and the discharge portion 141 has a discharge surface 141 a that is inclined upward toward the upstream side of the belt passage 140 . The second cutting part 152 is connected to the front wall 131 a and the rear wall 131 b of the receiver 130 . The lining tape PT is unrolled from a unshown unwinding portion, introduced into the tape passage 140 from the right introduction portion 142 , passes through the tape passage 140 , and discharged from the left discharge portion 141 . The pad tape PT discharged from the belt passage 140 is wound up by a winding part (not shown). Therefore, the belt passage 140 can be said to be along the left-right direction. Reference numeral 148 in FIG. 6 is a conveyor roller for discharging the liner tape PT from the belt passage 140 , and reference numeral 149 is a driven roller that passes the liner tape PT between the conveyor roller 148 and the liner tape PT. In addition, the conveying roller 148 and the driven roller 149 may be interlocked with each other using gears, etc., so that the conveying roller 148 and the driven roller 149 may be rotated simultaneously. The conveying roller 148 is driven to rotate intermittently by a drive source (for example, a motor) not shown. Thereby, the pad tape PT is intermittently conveyed to the tape passage 140.

As will be discussed later, the position of the tape passage 140 between the first opening 133 and the second opening 153 is used to cut the pad tape PT using the first cutting part 151 and the second cutting part 152 to form the circular pad 30. Location. As described above, the belt passage 140 along the left-right direction can be said to intersect or be orthogonal to the movement path along the up-down direction between the initial position and the mounting position of the fixing member 20 . Furthermore, the cutting position is set at the intersection of the movement path and the belt passage 140 . An upper portion of the rear wall 131 b of the receiver 130 is provided with a receiving portion 134 for receiving the fixing member 20 supplied from the conveying mechanism 300 to the button mounting device 100 . The fixing member 20 received from the receiving portion 134 is placed in the holding portion S in the initial state.

As shown in FIG. 5 , the second cutting portion 152 is a plate having substantially the same shape as the outer shape of the peripheral side wall 131 of the receiver 130 . The second cutting part 152 has a circular second opening 153 in the center. The diameter of the second opening 153 is substantially the same as the outer diameter of the first cutting part 151 , and is a size that can just accommodate the first cutting part 151 . The boundary between the peripheral surface defining the second opening 153 and the lower surface of the second cutting part 152 becomes the second cutting edge 154 . The second cutting part 152 supports the lining tape PT from above when the first cutting part 151 penetrates the lining tape PT from the bottom to above as discussed later. Furthermore, in this embodiment, the second cutting portion 152 functions to support the blank f to which the button body 10 is attached using the upper surface.

Next, the process of attaching the button main body 10 to the blank f using the button attaching device 100 will be described. FIG. 7 is an enlarged view showing a state immediately before the cutting unit 150 cuts the lining tape PT. FIG. 8 is a cross-sectional view of the button attaching device 100 immediately after the lining tape PT is cut. FIG. 9 is a cross-sectional view of the button attaching device 100 showing a time point when the rise of the annular member 120 is restricted by the receiver 130 . FIG. 10 is a cross-sectional view of the button attachment device 100 showing the time when the fixing member 20 reaches the attachment position. In the initial state shown in FIG. 6 , the fixing member 20 is supplied from the conveyance mechanism 300 to the button attaching device 100 and is held in the holding portion S. On the other hand, the button body 10 is held by the upper mold 200 . The blank f is arranged on the second cutting part 152 of the button attachment device 100. Furthermore, the pad tape PT passes through the tape passage 140 . The backing tape PT is stopped during the process of attaching one button body 10 to the blank f. When the plunger 160 located at the lowest point starts to rise from the initial state, the moving member 110 and the annular member 120 rise, and the fixed member 20 also rises from the initial position by the moving member 110 . Next, as shown in FIG. 7 , the upper end of the column 22 of the fixing member 20 and the first cutting portion 151 come into contact with the pad tape PT. In this example, the upper end of the column 22 is located slightly above the first cutting edge 151a of the first cutting part 151. Therefore, when the first cutting edge 151a comes into contact with the lining tape PT, the fixing member 20 Post 22 slightly lifts pad strip PT.

If the moving member 110 and the annular member 120 further rise from the time point in FIG. 7 , as shown in FIG. 8 , the first cutting part 151 moves from the lower surface as the first surface of the lining tape PT to the upper surface as the second surface. The lining tape PT at the cutting position is cut into a circular shape by the first cutting edge 151a of the first cutting part 151 and the second cutting edge 154 of the second opening 153 while penetrating the surface. Thus, the circular spacer 30 is formed. By sandwiching and cutting the lining tape PT with the lower first cutting edge 151a and the upper second cutting edge 154, the lining tape PT can be cut at once without forming a cut or the like in the lining tape PT in advance. In addition, since the lining tape PT is cut at the cutting position that is the intersection of the movement path of the belt passage 140 and the fixing member 20, the lining 30 and the fixing member 20 can be automatically aligned, and the center of the lining 30 and the fixing member can be automatically aligned. The center of 20 will not deviate.

Next, the moving member 110 and the annular member 120 continue to rise. At this time, the pad 30 is supported by the first cutting edge 151a of the first cutting part 151 (and the column 22 of the fixed member 20 in this example) and rises. Furthermore, at the timing shown in FIG. 9 , the thick-walled portion 121 of the annular member 120 comes into contact with the upper wall 132 of the receiver 130 to restrict upward movement. After that, the plunger 160 continues to rise, so the compression spring 115 between the thick wall portion 121 of the annular member 120 and the plunger 160 starts to shrink in the vertical direction. The moving member 110 also continues to rise together with the plunger 160, whereby the upper end of the elongated hole 113 is separated from the connecting shaft 114. In addition, the posts 22 of the fixed member 20 lifted up by the moving member 110 penetrate upward through the gasket 30 and then through the blank f to reach the installation position shown in FIG. 10 . At this time, the post 22 of the fixing member 20 passes upward through the opening 13 of the button body 10 . At the time of FIG. 10 , the plunger 160 and the moving member 110 are at the uppermost point and stop rising. Furthermore, the column 22 of the fixing member 20 is riveted to the button body 10 held by the upper mold 200, so that the pad 30 is sandwiched between the base 21 of the fixing member 20 and the blank f, and the button body 10 is attached to the button body 10. Blank f. Thereafter, when the plunger 160 and the moving member 110 return to the lowest point, the pad tape PT is conveyed downstream by one pad 30 in the tape passage 140 .

FIG. 11 is a cross-sectional view of the button attachment device 100a according to the second embodiment of the present invention. The main point in the structure of the button mounting device 100a that is different from the button mounting device 100 of the first embodiment is that the second cutting portion 152a is disposed at the upper end portion of the receiver 130a that is in contact with the upper wall 132a of the receiver 130a. This point; the point that the belt guide 143 is provided to support the pad tape PT passing through the belt passage 140 from below; the point that the edge position of the second cutting edge 154a of the second cutting portion 152a changes in the axial direction (up and down direction) . Since the structure other than these is substantially the same as that of the button attachment device 100 already described, the same reference numerals as those of the button attachment device 100 will be used, and description thereof will be omitted. In the button mounting device 100a, the upper wall 132a of the receiver 130a supports the blank f using its upper surface. The belt guide 143 is arranged below the second cutting part 152a with a slight gap therebetween, and the belt passage 140 is set between the second cutting part 152a and the belt guide 143. The belt guide 143 is supported on the front and rear walls of the receiver 130a.

The belt guide 143 has an opening 143a in the center. The second cutting part 152a also has a second opening 153a in the center. Furthermore, the upper wall 132a of the receiver 130a also has a first opening 133a in the center. The diameter of the second opening 153a is substantially the same as the outer diameter of the first cutting part 151, and is a size that can just accommodate the first cutting part 151. The first opening 133a is slightly larger than the second opening 153a, and the opening 143a is slightly larger than the second opening 153a. In the button attachment device 100a, when the moving member 110 rises together with the annular member 120 to move the fixing member 20 from the initial position to the attachment position, the first cutting edge 151a of the first cutting part 151 passes through the tape guide. After opening 143a of 143, the pad tape PT located at the cutting position of the tape passage 140 is cut between it and the second cutting edge 154a of the second cutting part 152a to form a circular pad 30. Next, the thick portion 121 of the annular member 120 comes into contact with the belt guide 143 to restrict upward movement. After that, the moving member 110 also continues to rise, causing the fixed member 20 to move to the installation position. Then, the button body 10 is attached to the blank f while the pad 30 is sandwiched between the base 21 of the fixing member 20 and the blank f.

FIG. 12 is an enlarged view showing a state immediately before cutting the lining tape PT by the first cutting part 151 and the second cutting part 152a in the button attaching device 100a. The position of the second cutting edge 154a of the second cutting part 152a changes in the axial direction. To be more specific, the first set of two cutting edge positions 154aa that are spaced 180 degrees apart from each other in the second cutting edge 154a is located in the axial direction closest to the lining tape PT side (second surface) of the belt passage 140 The two cutting edge positions 154ab of the second group (only one cutting edge position 154ab is shown in the figure) that are 90 degrees apart from the cutting edge position 154aa of the first group are located at the farthest position from the lining tape PT. Furthermore, the second cutting edge 154a gradually changes the cutting edge position from the cutting edge position 154aa of the first group to the cutting edge position 154ab of the second group. By thus changing the cutting edge position of the second cutting edge 154a in the axial direction, the lining tape PT can be cut gradually, and the load required for cutting the lining tape PT can be reduced.
