Description

Slider pass-through mechanism

Technical field

The present invention relates to a slider passing mechanism, and more specifically, to a mechanism for passing a zipper chain through a slider.

Background technique

In the process of manufacturing a plurality of zippers using long zipper chains, slider penetration is performed so that the zipper chain is passed through the slider. In the manufacture of slide fasteners, element rows are usually attached to the opposing edges of a pair of left and right elongated zipper tapes constituting the zipper chain, and the element rows are partially removed at predetermined intervals in the length direction to form spacing portions. , cut the zipper chain at the interval portion to obtain a pair of left and right zipper chain tapes with a predetermined length per unit length in the longitudinal direction. Slider threading is generally a process of attaching the slider to the zipper chain.

Referring to FIGS. 6 and 7 , the slider 1 includes an upper wing 2 , a lower wing 3 , and a guide post 4 connecting the upper wing 2 and the lower wing 3 . A substantially Y-shaped element guide path 5 is defined between the upper wing plate 2 and the lower wing plate 3 of the slider 1 . The element guide path 5 opens to two shoulder openings 5a on the left and right sides of the guide column 4, and opens to one rear opening 5b on the opposite side to the guide column 4. In the slider insertion, the slider 1 is attached to the slider chain by passing the element rows 12 of each of the left and right pair of fastener stringers 11 (see FIG. 1 etc.) into the element guide path 5 of the slider 1 Take 11.

Japanese Patent Application Publication No. 2004-215771 (Patent Document 1) discloses a slide fastener processing device including an example of a slider insertion mechanism. Patent Document 1 describes a one-way opening specification in which one slider is attached to a zipper stringer and a reverse opening specification in which two sliders are attached to a zipper stringer. In the one-way opening specification, there are cases where the element row of each fastener stringer is passed from the rear opening of the slider to the shoulder opening (refer to Figure 3 of this document), and there are cases where the element row is passed from the shoulder opening to the rear opening (refer to this document) Figure 4). In the reverse opening specification, the element row of each zipper stringer may be passed from the shoulder opening of one slider to the rear opening, and then passed from the rear opening of the other slider to the shoulder opening (see Figure 5 of this document) ), and the case of passing from the rear opening of one slider to the shoulder opening and then passing through the shoulder opening of the other slider to the rear opening (see Figure 6 of this document).

Referring to Figure 3 of this document, etc., the slider insertion mechanism described in Patent Document 1 includes: a pair of left and right clamps 114 that hold the zipper chain 2; slider holding portions 120 and 130 that hold the slider 1; and a moving mechanism ( Clamp moving mechanism) for moving the clamp 114 in the X-axis direction along the length direction of the zipper chain 2 and in the Y-axis direction along the left and right, that is, the width direction of the zipper chain 2; and a numerical control unit 140. The clamp moving mechanism includes an X-axis conveyor base 101, an X-axis drive electric motor 103, a clamp device 110, a moving base 111, a Y-axis conveyor base 113, a Y-axis drive electric motor 117, and the like. The clamp moving mechanism moves the clamp 114 in the X-axis direction and the Y-axis direction based on instructions from the numerical control unit 140 . The numerical control unit 140 stores in advance various data related to specifications such as sizes and materials of various sliders, zipper chains, element rows, etc., data such as movement trajectories corresponding to the combination of the slider and zipper chain, and clamps. Movement mechanism sequence control program, etc. (refer to paragraphs 0019, 0020, 0045, 0051, etc. of Patent Document 1). The numerical control unit 140 moves the clamp 114 in the X-axis direction and the Y-axis direction along a movement trajectory corresponding to a specific combination of the slider and the zipper chain having the element row via the clamp moving mechanism, thereby being gripped by the clamp 114 The element row of the zipper chain being held passes through the slider held by the slider holding part.

Next, a case where the element row of the fastener chain 2 is inserted from the rear opening to the shoulder opening of the slider 1 using the slider insertion mechanism disclosed in Patent Document 1 and the like will be described with reference to the drawings. FIG. 1 is a top view just before the zipper chain 2 is passed through the slider 1 . At this time, the slider 1 is held by the slider holding part, and the left and right fastener stringers 3 are in a state where the element rows are meshed with each other, and are held by the left and right clamps 114 . By the clamp moving mechanism, the clamp 114 first moves to the downstream side in the X-axis direction (upward on the paper surface of FIGS. 1 to 4 ) from the time point in FIG. 1 . Thereby, the element row of the fastener chain 2 enters the element guide path 5 from the rear opening of the slider 1 .

FIG. 2 is a plan view of the first few fastener elements from the downstream side of the fastener chain 2 when they enter the slider 1 . From the time point in FIG. 2 , the clamp 114 moves downstream in the X-axis direction and also moves outward in the Y-axis direction (the side where the left and right clamps 114 are away from each other). Thereby, the element rows of the left and right fastener stringers 3 go to the left and right shoulder openings of the element guide path while being separated, and then the element rows come from the shoulder openings to the outside of the slider 1 . FIG. 3 is a plan view showing a state in which a part of the downstream side of the element row of the fastener stringer 3 comes to the outside of the slider 1 . After several fastener elements on the downstream side exit from the shoulder of the slider 1, the movement of the clamp 114 in the Y-axis direction stops and only moves toward the downstream side in the X-axis direction. In this way, the slider 1 is attached to the fastener chain 2 .

The clamp moving mechanism moves the clamp 114 in the X-axis direction and the Y-axis direction so that the element rows of each fastener stringer 3 are preset in accordance with the substantially Y-shaped element guide path along the slider 1 moving trajectory forward.

The present inventors discovered that if the movement of the clip by the clip moving mechanism as described above is made faster, the following disadvantages may occur. FIG. 4 is an enlarged view of circle C in FIG. 2 . When the fastener element row 12 of the fastener chain 10 enters the element guide path 5 from the rear opening 5 b of the slider 1 by the high-speed moving jig 20 (see FIGS. 2 and 4 ), the element row 12 exceeds the preset limit. According to the motion trajectory, the timing of separation between the left and right chain element rows 12 will be slightly delayed. Thereby, the leading fastener element 12a on the downstream side collides with the guide pillar 4. Therefore, several fastener elements 12a from the frontmost on the downstream side may be damaged or damaged. FIG. 5 is a plan view conveniently showing the left fastener stringer 11 of the damaged fastener element row.

Contents of the invention

One object of the present invention is to provide a slider threading mechanism that does not cause damage to the fastener elements when the zipper chain is threaded through the slider at high speed.

In order to solve the above-mentioned problems, according to the present invention, a slider pass-through mechanism is provided, which includes: a slider holding mechanism including a slider holding part that holds the slider; left and right holding members that hold the zipper chain; and a moving mechanism. , which is used to move the holding member holding the zipper chain so that the element row of the zipper chain is moved downstream from the rear opening of the slider held by the slider holding part toward the shoulder opening. The slider holding mechanism includes a movable portion that allows the slider to be displaced toward the downstream side when the element row is in contact with the slider.

In this specification, the length direction of the zipper chain is the X-axis direction, and the zipper chain moves from the upstream side to the downstream side in the X-axis direction. In addition, the left-right (width) direction of the zipper chain is the Y-axis direction. In addition, in this specification, a pair of left and right fastener stringers in which a fastener chain is cut into a predetermined longitudinal unit length is also called a fastener chain.

In the slider insertion mechanism according to the present invention, the fastener chain is inserted from the rear opening of the slider held by the slider holding part toward the shoulder opening toward the downstream side in the X-axis direction. The zipper chain is held by the left and right holding members, and the control unit moves the holding members in the X-axis direction and the Y-axis direction via the moving mechanism so as to advance according to a preset movement trajectory. Thereby, pass the zipper chain through the slider. If the holding member is moved at a higher speed, the element array of the zipper chain may exceed the movement trajectory and come into contact with the guide pillar of the slider. In this case, in the present invention, the movable portion displaces the slider to the downstream side in the X-axis direction to escape, thereby preventing the element row from being damaged or damaged.

In the present invention, as the moving mechanism, in addition to the clamp moving mechanism described in Patent Document 1 (X-axis conveyor table 101, X-axis driving electric motor 103, clamp device 110, moving table 111, Y-axis conveyor table 113, Y-axis In addition to the driving electric motor 117, etc.), a cam mechanism, etc. can also be used.

In one embodiment of the present invention, the movable portion includes a downstream step portion defining at least a portion of the slider holding portion and supporting the slider when the slider is displaced toward the downstream side. The slider holding mechanism includes: a support portion that displaceably supports the movable portion; and an elastic member that urges the movable portion toward the upstream side. In this form, the movable portion located at the initial position, that is, the non-displaced position holds at least a part of the slider and is biased toward the upstream side in the X-axis direction by the elastic member. When the element row of the fastener chain comes into contact with the guide post of the slider in this state, the slider comes into contact with the downstream step portion of the movable portion and presses the movable portion toward the downstream side. Thereby, the movable part is displaced downstream together with the slider against the biasing force of the elastic member. At this time, the elastic member is compressed in the X-axis direction. When the element row is no longer in contact with the guide post, the elastic member recovers, and the movable part returns to the initial position on the upstream side together with the slider. As the elastic member, spring, rubber, elastomer, etc. can be used.

In one embodiment of the present invention, the movable portion includes: a first movable portion that defines a downstream portion of the slider holding portion and includes the downstream step portion; and a second movable portion , which defines the upstream side portion of the slider holding portion. In this form, the first movable portion defines the downstream portion of the slider holding portion, the second movable portion defines the upstream portion of the slider holding portion, and the slider is held throughout the upstream portion and the downstream portion. The downstream side step portion is provided in the first movable portion. When the element row of the zipper chain comes into contact with the guide pillar of the slider, the first movable portion supports the slider that is pressed toward the downstream side using the downstream side step portion, and is displaced toward the downstream side together with the slider. At this time, the second movable portion is displaced downstream due to friction with the slider that is displaced downstream. In this way, since the second movable part is also displaced together with the slider, the slider will not be damaged. The support part supports the first movable part and the second movable part. In addition, the support part may be divided into a first support part that supports the first movable part and a second support part that supports the second movable part.

In one embodiment of the present invention, the slider includes: a locking mechanism; and a pull tab capable of switching between locking and unlocking of the locking mechanism according to posture or position, and the slider retaining mechanism includes a locking release The lock releasing mechanism can maintain the attitude or position of the pull tab that unlocks the locking mechanism when the slider is displaced and when it is not displaced. The locking mechanism is a mechanism that locks or unlocks the slide of the slider relative to the element row by protruding or retracting the locking pawl relative to the element guide path of the slider and contacting or separating relative to the element located on the element guide path. Known institutions. The lock release mechanism in the slider holding mechanism is used to maintain the pull tab in a position or posture that releases the lock of the lock mechanism when the slider is displaced from the initial position and when it is in the initial position (when not displaced). Thereby, even if the slider is displaced, the element row can be inserted into the element guide path.

In one embodiment of the present invention, the second elastic member is provided to urge the second movable portion downstream. In this form, the first movable portion is biased toward the upstream side by the elastic member (first elastic member), and the second movable portion is biased toward the downstream side by the second elastic member. When the slider is displaced downstream in this state, the first movable portion is displaced downstream against the urging force of the first elastic member, and the second movable portion is displaced downstream due to the urging force of the second elastic member. Therefore, the second movable part can be displaced downstream together with the slider without relying on friction between the second movable part and the slider. The spring constant of the second elastic member is set smaller than the spring constant of the first elastic member.

The slider insertion mechanism of the present invention includes a control unit for operating the moving mechanism, and the movement locus of the gripping member is stored in advance in the control unit. The control unit moves the holding member in the X-axis direction and the Y-axis direction through the moving mechanism so as to advance according to a preset movement trajectory, so that the element row of the zipper chain held by the holding member is passed through The slider is held by the slider holding part.

According to another aspect of the present invention, there is provided a slider holding mechanism that includes a slider holding portion that holds a slider that passes an element row of a zipper chain toward a downstream side, the slider holding mechanism being included in the chain. A movable part that allows the slider to be displaced toward the downstream side when the tooth row is in contact with the slider.

Invention effect

In the present invention, when the holding member is moved downstream at high speed by the moving mechanism, even if the element row of the zipper chain exceeds the movement trajectory and comes into contact with the guide post of the slider, the movable portion can displace the slider downstream. And the excess amount is absorbed, so the chain teeth will not be damaged or damaged. Therefore, the zipper chain can be moved at a higher speed during the slider passing process.

The slider pass-through mechanism includes: a slider holding mechanism 40, 140 that holds the slider 1 (refer to Figures 6, 10, etc.); and left and right clamps 20 as holding members that hold the zipper chain 10 (refer to Figure 1, etc.) ; The moving mechanism 30 is used to move the clamp 20 in the X-axis direction and the Y-axis direction; and the control unit 80 is used to operate the moving mechanism 30 (see Figure 8). The slider insertion mechanism of the present invention includes the following improved slider holding mechanisms 40 and 140, a clamp 20, a moving mechanism 30, and a control unit 80. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-215771) can be used. Known structures such as the clamp, clamp moving mechanism, and action control unit (numerical control unit) described in .

6 is a partial cross-sectional side view showing the slider holding mechanism 40 in the first embodiment of the slider insertion mechanism according to the present invention, showing the slider 1 to be held by the slider holding mechanism 40 from above. In the paper of FIG. 6 , the left-right direction is the X-axis direction, the right side is the downstream side in the X-axis direction, and the left side is the upstream side in the X-axis direction. Hereinafter, the downstream side or the upstream side in the X-axis direction will also be simply referred to as the downstream side or the upstream side. The slider holding mechanism 40 includes a first movable part 50 on the downstream side and a second movable part 60 on the upstream side as movable parts; and a support part 41 that supports the first movable part 50 and the second movable part. 60; a spiral spring 42 as an elastic member (first elastic member) that urges the first movable part 50 toward the upstream side; and a lock release mechanism 70. FIG. 7 is a perspective view of the first movable part 50 , the second movable part 60 , the spring 42 and the lock release mechanism 70 , together with the slider 1 . FIG. 8 is a block diagram schematically showing the control structure of the slider insertion mechanism.

In this example, the support portion 41 includes a first support portion 41A on the downstream side that supports the first movable portion 50 from below, and a second support portion 41B on the upstream side that supports the second movable portion 60 from below. , however, the first support part 41A and the second support part 41B may be integrated. In addition, the first support part 41A and the second support part 41B may be formed so as to be able to approach or separate from each other in the X-axis direction. Thereby, the distance between the 1st support part 41A and the 2nd support part 41B can be enlarged, and the operability when the slider holding mechanism 40 holds the slider 1 can be improved. The first movable part 50 is displaceable relative to the first support part 41A, and the second movable part 60 is displaceable relative to the second support part 41B. The slider holding mechanism 40 has a slider holding part 40a in the upper part of the 1st movable part 50 and the 2nd movable part 60. This slider holding part 40a is recessed downward and is used for placing and holding the slider 1. The slider holding mechanism 40 is raised and lowered between the upper operating position and the lower standby position by a lifting mechanism (not shown). The slider 1 is conveyed toward the slider holding part 40a of the slider holding mechanism 40 in an operating position by the conveyance device etc. which are not shown, and the slider 1 is placed in the slider holding part 40a.

The slider 1 includes an upper wing plate 2 , a lower wing plate 3 , and a guide post 4 connecting the upper wing plate 2 and the lower wing plate 3 . A substantially Y-shaped element guide path 5 is defined between the upper wing plate 2 and the lower wing plate 3 . The element guide path 5 opens to two shoulder openings 5a on the left and right sides of the guide column 4, and opens to one rear opening 5b on the opposite side to the guide column 4. The slider 1 includes a pull tab 6 . The handle 6 has the connection ring part 6a (refer FIG. 7) which is connected with the handle connection part 2a protruding from the upper surface of the upper wing plate 2 (the upper surface faces downward in FIG. 6). The slider 1 also includes a locking mechanism. The locking mechanism is a known mechanism in which a lock claw (not shown) protrudes or retracts from the upper wing plate 2 side toward the element guide path 5 to contact the element 12a (see FIG. 1 etc.) located on the element guide path 5 or separated, thereby locking or unlocking the slide of the slider 1 with respect to the element row 12 . The lock release mechanism 70 in the slider holding mechanism 40 is for maintaining the lock mechanism of the slider 1 held by the slider holding part 40a in the unlocked state.

The first support portion 41A supports the first movable portion 50 so as to allow the first movable portion 50 to slide and displace only in the X-axis direction. In addition, the first support portion 41A includes a spring support member 43 that expands upward and downstream to support the downstream end of the spring 42 . The spring 42 is arranged between the downstream end surface 50 a of the first movable part 50 and the spring support member 43 of the first support part 41A, and urges the first movable part 50 toward the upstream side. The second support portion 41B supports the second movable portion 60 so as to allow the second movable portion 60 to slide and displace only in the X-axis direction. In addition, the second support portion 41B includes a support surface 44 that supports the upstream end surface 60 a of the second movable portion 60 . The support surface 44 restricts the upstream displacement of the second movable part 60 .

The first movable part 50 has first raised parts 51 on both left and right sides respectively. The first raised portion 51 protrudes toward the upstream side of the upstream end surface 50 b of the first movable portion 50 . The second movable part 60 also has second raised parts 61 on both left and right sides. The downstream end surface of the second raised portion 61 and the downstream end surface 60b (see FIG. 7 ) of the second movable portion 60 are located on the same plane. In the slider holding mechanism 40 , except for the case where the element row 12 comes into contact with the slider 1 during the slider insertion operation described below, the first movable part 50 and the second movable part 60 are located as shown in FIG. 6 Initial position of the most upstream side. In this initial position, the first movable part 50 is pressed upstream by the spring 42, so that the upstream end surface of the first raised part 51 comes into contact with the downstream end surface of the second raised part 61, and the second movable part 60 is pressed The spring 42 indirectly presses the upstream side via the first movable part 50 , but the second movable part 60 is supported by the support surface 44 of the second support part 41B and does not move further upstream. At this time, the first raised portion 51 of the first movable portion 50 also conflicts with the second raised portion 61 of the second movable portion 60 and does not move further to the upstream side.

A gap G exists between the upstream end surface 50 b (see FIG. 7 ) of the first movable part 50 and the downstream end surface 60 b of the second movable part 60 . This gap G is always ensured because the first raised portion 51 of the first movable portion 50 protrudes upstream from the upstream end surface 50 b. The slider 1 is placed on the slider holding part 40a of the slider holding mechanism 40 with the upper wing 2 facing downward and the lower wing 3 facing upward. At this time, the handle 6 is accommodated in the gap G between the first movable part 50 and the second movable part 60 . The interval in the X-axis direction of the gap G is a size larger than the thickness of the handle 6 but capable of suppressing the displacement of the handle 6 in the X-axis direction to a minimum.

The first movable part 50 includes an upstream half part 52 and a downstream half part 53 . The upper surface 52a of the upstream half 52 substantially constitutes the downstream half of the slider holding portion 40a. The second movable part 60 includes an upstream frame part 62 and a downstream part 63 protruding from the frame part 62 to the downstream side. The upper surface 63a of the downstream part 63 substantially constitutes the upstream side half of the slider holding part 40a. The upstream half portion 52 of the first movable portion 50 is provided with a first cavity portion 54 that penetrates vertically and opens to the upstream side. A second cavity portion 64 is provided in the downstream portion of the second movable portion, penetrating vertically and opening to the downstream side. When the slider 1 is placed on the slider holding part 40a, the handle connection part 2a of the slider 1 is accommodated in the 1st cavity part 54 and the 2nd cavity part 64.

In the first movable part 50 , the downstream half 53 is slightly higher than the upstream half 52 , and the downstream step 55 serving as a slider support is located between the upper surface of the upstream half 52 and the downstream half 53 . The boundary between upper surfaces. In the second movable part 60 , the frame part 62 protrudes upward from the downstream part 63 , and the upstream step part 65 is located at the boundary between the upper surface of the downstream part 63 and the upper surface of the frame part 62 . The downstream step portion 55 is the downstream side surface of the slider holding portion 40a, and the upstream side step portion 65 is the upstream side surface of the slider holding portion 40b. The frame portion 62 is provided with an opening 62 a having an elliptical cross-section that penetrates in the X-axis direction and is long in the up-down direction. The frame portion 62 includes left and right side portions 62b and an upper and lower portion surrounding the opening 62a.

The lock release mechanism 70 includes an elongated plate-shaped lock release member 71 and a tension spring 72 as an elastic member that functions to maintain the lock release member 71 in an initial position described below. The lock release member 71 includes a lock release claw 71 a formed at a downstream end portion of the lock release member 71 , and a pivot portion 71 b protruding left and right at substantially the middle portion in the longitudinal direction. The lock release member 71 penetrates the opening 62a of the frame portion 62 of the second movable portion 60, and the left and right pivot portions 71b are rotatably supported on the left and right side portions 62b of the frame portion 62 below the upper and lower intermediate portions. The shaft support hole 62c is provided. The lock release claw 71a is located on the downstream side of the opening 62a, and the upstream end portion 71d of the lock release member 71 is located on the upstream side of the opening 62a. The upper end of the tension spring 72 is connected to a fixed shaft 73 extending between the upper ends of the left and right side portions 62b in the opening 62a of the frame portion 62. The lower end of the tension spring 72 is connected to a spring connection hole 71 c provided in a portion of the lock release member 71 on the upstream side of the opening 62 a.

In FIGS. 6 and 7 , the lock release member 71 is in the initial position. At this initial position, the lock release claw 71a is inclined downstream and upward with respect to the pivot portion 71b, and enters the gap G between the first movable portion and the second movable portion. In addition, the upstream end portion 71d of the lock release member 71 is inclined upstream and downward with respect to the pivot portion 71b at the initial installation position. When the lock release pawl 71a is pressed upward from the initial position (in the counterclockwise direction centered on the pivot portion 71b in the paper of FIG. 6), the tension spring 72 moves the lock release pawl 71a back to the initial position. The lock release claw 71a is biased. When the slider 1 is placed on the slider holding part 40a of the slider holding mechanism 40, the pull tab 6 is accommodated in the gap G between the first movable part 50 and the second movable part 60, and the lock release claw 71a enters Connect the ring part 6a. At this time, since the lock release claw 71 a is slightly displaced upward from the initial position, the lock release claw 71 a is biased toward the initial position side by the tension spring 72 . Thereby, the pull tab 6 is disposed in the gap G in a state of being stretched substantially vertically downward, so that the locking mechanism of the slider 1 placed on the slider holding part 40a is maintained in the unlocked state, and the zipper chain 10 can be The fastener element row 12 penetrates the fastener element guide path 5 of the slider 1 .

Next, the slider passing through by the slider passing through mechanism of 1st Embodiment is demonstrated. 1 to 4 used in the description of the conventional art are generally common in the description of the slider insertion mechanism of the present invention, and therefore these figures are used. FIG. 1 is a plan view showing the initial state of the slider 1 and the fastener stringer 11 . The element row 12 in FIG. 1 etc. is made of resin and is injection-molded to the fastener tape 11a of the fastener stringer 11, but it is not limited to this and may be metal or a spiral monofilament. In addition, the up-down direction on the paper surface of FIGS. 1-4 is along the X-axis direction, and the left-right direction is along the Y-axis direction. In addition, the downstream side in the X-axis direction is the upper side on the paper surface of FIG. 1 , and the upstream side in the X-axis direction is the lower side on the paper surface of FIG. 1 . The upstream side and the downstream side in the X-axis direction are also simply called the upstream side and the downstream side. Hereinafter, the side where the left and right clamps 20 are close to each other in the Y-axis direction is called the Y-axis direction inner side, and the side which is far away from each other is called the Y-axis direction outer side. In the initial state, the slider 1 is held by the slider holding part 40a of the slider holding mechanism 40. In addition, the left and right pair of fastener stringers 11 are held by the left and right clamps 20 in a state in which the element rows 12 on the upstream side of the slider holding mechanism 40 are meshed with each other. Each clamp 20 holds the Y-axis direction outer edge part near the downstream end of the fastener tape 11a of each fastener stringer 11. Reference numeral 13 in FIG. 1 is a spacer formed by removing a part of the element row 12 . The opening and closing of the clamp 20 and the movement in the X-axis direction and the Y-axis direction are performed by the moving mechanism 30 based on the operation signal from the control unit 80 . The control unit 80 stores in advance various data, motion trajectories, control programs, and the like corresponding to the specifications of the zipper chain 10 including the slider 1, the element rows 12, and the like.

From the time point in FIG. 1 , the clamp 20 is first moved to the downstream side by the moving mechanism 30 . Thereby, the element row 12 of the fastener chain 10 enters the element guide path 5 from the rear opening 5b of the slider 1. FIG. 2 is a plan view of the first few fastener elements 12 a from the downstream side of the fastener chain 10 when they enter the slider 1 . The slider 1 has a gap through which the fastener tape 11a passes between the upper wing plate 2 and the lower wing plate 3 . From the time point in FIG. 2 , the clamp 20 starts to move outward in the Y-axis direction while moving toward the downstream side. Thereby, the element rows 12 of the left and right fastener stringers 11 go to the left and right shoulder openings 5a of the element guide path 5 while being separated, and then the element rows 12 come to the outside of the slider 1 from the shoulder openings 5a. FIG. 3 is a plan view showing a state in which a part of the downstream side of the element row 12 of the fastener stringer 11 comes to the outside of the slider 1 . After several fastener elements 12a on the downstream side exit the shoulder opening 5a of the slider 1, the clamp 20 stops moving in the Y-axis direction and moves only to the downstream side. Thereby, the upstream side part of the element row 12 which has not yet entered the slider 1 penetrates the slider 1 along the element guide path 5, and the slider penetration operation is completed.

During the above slider passing process, the moving mechanism 30 moves the clamp 20 in the X-axis direction and the Y-axis direction so that the element rows 12 of each zipper stringer 11 follow a substantially Y-shape along the slider 1 The preset movement trajectory of the element guide path 5 advances. FIG. 4 is an enlarged view of circle C in FIG. 2 . The fast-moving jig 20 causes the element row 12 of the zipper stringer 11 to enter the element guide path 5 from the rear opening 5 b of the slider 1 at the initial position (see FIGS. 2 and 4 ). The case where the leading fastener element 12a on the downstream side collides with the guide column 4 according to the preset movement trajectory. In this way, when the fastener element 12a comes into contact with the guide post 4, the slider 1 is pressed toward the downstream side, and the slider 1 presses the first movable portion 50 in the slider holding mechanism 40 toward the downstream side from the downstream side step portion 55 thereof. . Thereby, the first movable portion 50 is displaced downstream on the first support portion 41A against the biasing force of the spring 42 . FIG. 9 is a plan view showing a state in which the slider 1 and the first movable part 50 are displaced to the downstream side. At the time of FIG. 9 , the spring 42 is compressed in the X-axis direction. As described above, when the element 12a comes into contact with the guide pillar 4, the slider 1 is displaced from the initial position to the downstream side to escape, thereby preventing the element row 12 from being damaged or damaged. In addition, after the slider 1 is temporarily displaced downstream, the element row 12 returns to the predetermined movement trajectory, whereby the first movable part 50 and the slider 1 return to the upstream initial position due to the recovery of the spring 42 .

When the first movable part 50 is displaced downstream, the second movable part 60 is displaced downstream on the second support part 41B due to friction with the slider 1 which is displaced downstream. That is, friction acts between the upper surface (facing downward) of the upper blade 2 of the slider 1 and the surface defining the upstream half of the slider holding portion 40a in the second movable portion 60, so that The second movable part 60 is also displaced downstream together with the slider 1 . In this way, the second movable part 60 is also displaced together with the slider 1, so that the slider 1 is not damaged.

When the second movable part 60 is displaced downstream, the lock release member 71 and the tension spring 72 of the lock release mechanism 70 connected to the second movable part 60 also maintain the same posture with the second movable part 60 . 60 is displaced to the downstream side together. Therefore, the unlocking claw 71a maintains the posture of pulling the pull tab 6 of the slider 1 downward, and maintains the locking mechanism of the slider 1 in the unlocked state. Thereby, even if the slider 1 is displaced from the initial position, the insertion of the element row 12 into the element guide path 5 of the slider 1 can be continued. In addition, since the lock release mechanism 70 is also displaced together with the handle 6 in this way, the handle 6 will not be damaged. When the first movable part 50 and the slider 1 return to the initial position on the upstream side due to the recovery of the spring 42, the first raised part 51 presses the second raised part 61 upstream, and the second movable part 60 also returns Initial position in contact with support surface 44.

FIG. 10 is a partial cross-sectional side view showing the slider holding mechanism 140 in the second embodiment of the slider insertion mechanism according to the present invention. This slider insertion mechanism includes the same clamp 20, moving mechanism 30, and control unit 80 as the slider insertion mechanism of the first embodiment. In FIG. 10 , the slider 1 is held by the slider holding portion 140 a of the slider holding mechanism 140 . The slider holding mechanism 140 is mainly different from the already described slider holding mechanism 40 in the following aspects. That is, the second movable portion 160 is biased toward the downstream side by the second spring 142 as the second elastic member, and the lock release mechanism 70 is not provided. Since the structures other than the above are substantially the same as the slider holding mechanism 40, only a part of the structure is given the same reference numerals as in FIG. 6 and others, and a detailed description is omitted.

In the slider holding mechanism 140, the second movable part 160 is displaceably supported by the second support part 141B, and is biased toward the downstream side by the second spring 142. The second support portion 141B includes a spring support member 143 that supports the upstream end of the second spring 142 . The second movable part 160 has second raised parts 161 on both left and right sides. The spring constant of the second spring 142 is set smaller than the spring constant of the spring 42 .

In the initial state of FIG. 10 , the first movable part 50 is biased toward the upstream side by the spring 42 , and the first protruding part 51 presses the second protruding part 161 , that is, the second movable part 160 toward the upstream side. The second movable portion 160 is in a state in which the biasing force of the spring 42 to the upstream side via the first movable portion 50 and the biasing force of the second spring 142 to the downstream side are balanced. At this time, the second spring 142 is in a slightly compressed state. In this state, when the downstream-front element 12 a of the element row 12 of the zipper chain 10 comes into contact with the guide post 4 of the slider 1 during the slider insertion step, the slider 1 and the first movable portion 50 By being displaced downstream against the biasing force of the spring 42, the element row 12 can be prevented from being damaged or damaged. In addition, as the slider 1 and the first movable part 50 are displaced downstream, the second spring 142 expands and displaces the second movable part 160 downstream. Therefore, the 2nd movable part 160 also moves together with the slider 1, and does not cause damage to the slider 1. After the slider 1 is temporarily displaced to the downstream side, the element row 12 returns to the predetermined movement trajectory, so that the first movable part 50 and the slider 1 return to the initial position on the upstream side due to the recovery of the spring 42. The second movable part 160 also compresses the second spring 142 and returns to the initial position.
