Disclosure of Invention

However, in the slider conveying device described in patent document 2, since the slider is held by the slider conveying member in a state where the pull tab hangs down and the slider is conveyed in the width direction thereof, the pull tab is easily swung when the slider is conveyed. Further, since the slider is pneumatically operated by using an air cylinder, it is difficult to control the acceleration and deceleration of the slider conveying member, and the swing angle of the pull tab is large.

Therefore, conventionally, in order to insert the insertion portion of the slider holding device into the tab attaching hole of the tab, it is necessary to temporarily stop the driving of the slider holding device and the slider conveying device until the swing of the tab is smoothed, and thus the time required for one cycle for attaching the slider to the fastener stringer becomes long. Further, although it is possible to suppress the swing angle of the tab by reducing the moving speed of the slider conveying member, the problem is not solved because the time required for one cycle is also increased in this case. Further, if the time required for one cycle for attaching the slider to the fastener stringer becomes long, the operation time of one cycle of the slide fastener manufacturing apparatus becomes long, and therefore, the productivity of the entire apparatus is lowered.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a slide fastener manufacturing apparatus and a slide fastener manufacturing method capable of quickly conveying a slider while suppressing a swing angle of a pull tab, thereby shortening a time required for one cycle for attaching the slider to a fastener stringer.

The above object of the present invention is achieved by the following structure.

(1) A slide fastener manufacturing apparatus includes: a slider positioning member that holds a slider of a slide fastener and positions the slider at a position where the slider is attached to a fastener stringer; and a slider conveying member which moves between a 1 st position for holding the slider and a 2 nd position for transferring the slider to the slider positioning member, the slider positioning member including an insertion portion, the insertion part is inserted into a pull-tab mounting hole of a pull tab of the slider, the slider is held by the slider conveying member in a state where the pull tab hangs down, the zipper manufacturing device is characterized in that the slider conveying component is arranged in a mode of being capable of moving through a servo motor, a control unit for controlling the drive of the servo motor, wherein the control unit controls the moving speed of the slider conveying member so that the swing angle of the pull tab in a vertical plane along the slider conveying direction is equal to or smaller than an insertion allowable angle, wherein the insertion allowance angle is an angle that allows the insertion of the insertion portion into the tab attaching hole.

(2) The slide fastener manufacturing apparatus according to (1), wherein the control of the moving speed of the slider conveying member by the control unit is performed by controlling at least one of an acceleration at which the slider conveying member starts moving from the 1 st position and a deceleration at which the slider conveying member stops at the 2 nd position.

(3) A method for manufacturing a slide fastener, comprising the steps of: a conveying step of conveying the slider of the slide fastener to the slider positioning member; and a positioning step of positioning the slider at a position to be attached to a fastener stringer, wherein the slider is conveyed in the conveying step in a state where a pull tab of the slider is suspended, wherein an insertion portion of the slider positioning member is inserted into a pull tab attachment hole of the pull tab, and wherein the conveying speed of the slider is controlled in the conveying step so that a swing angle of the pull tab in a vertical plane along a slider conveying direction becomes equal to or smaller than an insertion allowance angle, wherein the insertion allowance angle is an angle allowing the insertion portion to be inserted into the pull tab attachment hole.

(4) The slide fastener manufacturing method according to the item (3), wherein the insertion portion is inserted into the tab attaching hole of the swing tab and then moved in the tab attaching hole, and the inner peripheral edge of the tab attaching hole is pressed to pull down the tab.

Effects of the invention

According to the slide fastener manufacturing apparatus of the present invention, the control section that controls the driving of the servo motor controls the moving speed of the tab conveying member so that the swing angle of the tab in the vertical plane along the slider conveying direction becomes equal to or smaller than the insertion allowable angle allowing the insertion portion to be inserted into the tab attaching hole. Accordingly, after the slider is conveyed to the 2 nd position, the insertion portion can be inserted into the tab attaching hole without waiting for the swing of the tab to be leveled, and therefore, the time required for one cycle for attaching the slider to the fastener stringer can be shortened, and further, the productivity of the fastener manufacturing apparatus can be improved.

Further, according to the method of manufacturing a slide fastener of the present invention, in the slider conveying step, the slider conveying speed is controlled so that the swing angle of the tab in the vertical plane along the slider conveying direction becomes equal to or smaller than the insertion allowable angle allowing the insertion portion to be inserted into the tab attaching hole. Accordingly, after the slider is conveyed to the slider positioning member, the insertion portion can be inserted into the tab attaching hole without waiting for the swing of the tab to be leveled, and therefore, the time required for one cycle for attaching the slider to the fastener stringer can be shortened, and further, the productivity of the slide fastener can be improved. Further, the insertion portion inserted into the tab attaching hole pushes the inner peripheral edge of the tab attaching hole of the tab in a swinging state to pull down the tab, so that swinging of the tab can be reliably stopped.

The rear side of the slide fastener manufacturing apparatus is also referred to as the upstream side, and the front side is also referred to as the downstream side. The left-right direction of the slide fastener manufacturing apparatus is also referred to as the width direction. The upstream side and the downstream side are based on the transfer direction of the continuous fastener stringer, the fastener stringer, and the slide fastener.

As shown in fig. 1, a slide fastener manufacturing apparatus 10 of the present embodiment includes: a transfer device 20 for transferring the continuous fastener stringer C1; a cutting device 30 for cutting the continuous fastener stringer C1 transferred by the transfer device 20 into a predetermined length of fastener stringer C2; a slider attaching device 40 for attaching a slider SL to the fastener stringer C2 transferred by the transfer device 20; a stopper mounting device 70 for mounting a first stopper P1 on the fastener stringer C2 transferred by the transfer device 20; and a discharge device 80 that receives the completed slide fastener SF to which the first stop portion P1 is attached from the transfer device 20 and discharges the slide fastener SF to a discharge portion, not shown. Note that reference symbol L in fig. 1 is a transfer line for transferring the continuous fastener stringer C1, the fastener stringer C2, and the slide fastener SF.

Here, a slide fastener SF assembled by the slide fastener manufacturing apparatus 10 of the present embodiment will be described. As shown in fig. 9, the slide fastener SF includes: a pair of right and left fastener tapes T; a pair of right and left fastener element rows EL provided on opposite tape side edge portions of the right and left fastener tapes T; a slider SL for engaging and disengaging the left and right fastener element rows EL; first stop portions P1 attached to one end of each of the left and right fastener element rows EL; and a 2 nd stopper portion P2 attached to the other end portions of the left and right fastener element rows EL.

In the present embodiment, the fastener element row EL is a spiral fastener element row, but is not limited to this, and may be a zigzag fastener element row, a fastener element row formed by injection molding of a synthetic resin, or a metal fastener element row.

The slider SL includes a slider body D and a tab P attached to a tab attachment portion D1 provided on the upper surface of the slider body D. The tab P has a tab attaching hole Pa at one end portion thereof.

The continuous fastener stringer C1 is formed by connecting a plurality of fastener stringers C2 to which the 2 nd stop portion P2 is attached in advance. In the present embodiment, the continuous fastener stringer C1 is supplied to the fastener manufacturing apparatus 10 such that the 2 nd stop portion P2 is located on the upstream side. When the continuous fastener stringer C1 is supplied to the fastener manufacturing apparatus 10, the left and right fastener element rows EL are engaged with each other.

The transfer device 20 transfers the continuous fastener stringer C1 to the downstream side while gripping the downstream end of the continuous fastener stringer C1, and the transfer device 20 includes: a pair of grippers 21 for gripping the left and right fastener tapes T of the continuous fastener stringer C1, respectively; and a moving device, not shown, which moves the pair of grippers 21 in the upstream and downstream directions.

The discharge device 80 grips the downstream end of the slide fastener SF to which the slider SL and the 1 st stop portion P1 are attached, and transfers the slide fastener SF to the discharge portion, and the discharge device 80 includes: a gripper 81 that grips the right and left fastener tapes T of the fastener SF; and a moving device, not shown, which moves the gripper 81 in the upstream and downstream directions. The gripper 81 is configured to grip the right and left fastener tapes T from the downstream side.

The slider mounting device 40 includes: a slider positioning member 50 which is disposed below the transfer line L, holds the slider SL, and positions the slider SL at a position to be attached to the fastener stringer C2 as shown in fig. 1; and a slider conveying member 60 for placing the slider SL on the upper end of the slider positioning member 50. The fastener stringer C2 passes through the element guide groove in the slider body D when attached to the slider SL.

As shown in fig. 3 to 5, the slider positioning member 50 includes: a pair of front and rear

slider holding members

51 and 52 for holding the slider SL; and an insertion portion 55 provided in the slider holding member 51 on the rear side and pulling down the tab P of the slider SL. The slider positioning member 50 is moved in the vertical direction by a driving device, not shown. The downward movement position is a position to receive the slider SL from the slider conveying member 60, and the upward movement position is a position to position the held slider SL at a position to attach to the fastener stringer C2.

The insertion portion 55 has an insertion claw 55a, and the insertion claw 55a extends downstream from the base portion and is inserted into the tab attachment hole Pa of the tab P. The insertion portion 55 is moved in the front-rear direction and in the up-down direction by a driving device, not shown. That is, as shown in fig. 4, the insertion portion 55 is moved forward to insert the insertion claw 55a into the tab attaching hole Pa, and then, as shown in fig. 5, the insertion portion 55 is moved downward. At this time, the insertion claw 55a of the insertion portion 55 moves in the tab attaching hole Pa, and comes into contact with the inner peripheral edge of the tab attaching hole Pa to press the inner peripheral edge of the tab attaching hole Pa. Thereby, the insertion portion 55 pulls down the tab P. Then, by pulling down the tab P, the swing of the tab P due to the transportation of the slider SL is stopped, and the slider SL is fixed to the slider positioning member 50. When the slider SL is a slider with an automatic stop function, a stop pawl of a locking member, not shown, built in the slider SL is retracted from an element guide path in the slider body D by pulling down the pull tab P.

The slider conveying member 60 is configured to move between a 1 st position G1 where the slider SL is held and a 2 nd position G2 where the slider SL is transferred to the slider positioning member 50. Specifically, as shown in fig. 2, the slide member 61 is movably provided on the ball screw 62 extending between the 1 st position G1 and the 2 nd position G2, and the slider conveying member 60 is attached to the slide member 61. The slider conveying member 60 holds the slider SL in a state where the tab P hangs down due to gravity. When the slider SL is conveyed by the slider conveying member 60, the tab P swings in the slider conveying direction.

Further, the slider SL is supplied to the slider conveying member 60 at the 1 st position G1 by the slider supply device 65. As shown in fig. 2, the slider feeding device 65 includes a slider feeding chute 66 that accommodates a plurality of sliders SL. The slider supply chute 66 supplies the slider SL on the lowermost end side in the chute to the slider conveying member 60 by an unillustrated feeding mechanism. The slider SL is accommodated in the slider supply chute 66 with the pull tab P hanging down.

The ball screw 62 is disposed so as to intersect (in the present embodiment, to be orthogonal to) the transfer line L in a plan view, and a drive shaft 64a of a servomotor 64 is connected to one end portion of the ball screw 62 via a coupling 63. Then, the ball screw 62 is rotated by the servo motor 64, and the slider conveying member 60 moves along the ball screw 62. That is, the slider conveying member 60 is provided so as to be movable by the servo motor 64.

The driving of the servomotor 64 is controlled by a control unit 68 (see fig. 1), and the control unit 68 controls the servomotor 64 so that the slider conveying member 60 can be accurately moved between the 1 st position G1 and the 2 nd position G2. Therefore, by controlling the rotation speed of the servo motor 64, the moving speed of the slider conveying member 60 can be controlled.

In the present embodiment, the control unit 68 controls the moving speed of the slider conveying member 60 so that the swing angle of the tab P becomes equal to or smaller than the insertion allowance angle α (see fig. 6) allowing the insertion claw 55a to be inserted into the tab attaching hole Pa with respect to the swing of the tab P caused by the conveyance of the slider SL. That is, the control unit 68 controls the moving speed of the tab conveying member 60 so as to promptly convey the slider SL while suppressing the swing angle of the tab P caused by inertia during slider conveyance. The swing angle of the tab P is a swing angle of the tab P in a vertical plane along the slider conveying direction (the longitudinal direction of the ball screw 62). The insertion allowance angle α is preferably controlled to 10 degrees or less. The insertion allowance angle α is a swing angle of the tab P to one side (right direction) in the slider conveying direction and to the opposite side to the one side, that is, the other side (left direction) in the slider conveying direction with respect to the axis AL of the tab P in a state of hanging down in the vertical direction.

As the control of the movement speed of the slider conveying member 60, as shown in the speed curve shown in fig. 7, both the acceleration at the time when the slider conveying member 60 starts moving from the 1 st position G1 and the deceleration at the time when the slider conveying member 60 stops at the 2 nd position G2 are controlled. Specifically, the control is performed so as to gradually accelerate from the start of the movement and gradually decelerate before the movement stops. Thus, since the swing angle of the tab P is suppressed, the insertion claw 55a of the insertion portion 55 can be inserted into the tab attaching hole Pa of the tab P in the swing state without waiting for the swing of the tab P to be leveled after the slider SL is conveyed to the 2 nd position G2 (see fig. 4). Further, between the slow acceleration and the slow deceleration, the movement speed of the slider conveying member 60 is controlled to be increased. This can shorten the moving time from the 1 st position G1 to the 2 nd position G2.

Further, the slide fastener manufacturing method in the slide fastener manufacturing apparatus 10 of the present embodiment includes: a transfer step in which the slider transfer member 60 transfers the slider SL to the slider positioning member 50; a transfer step in which the slider transport member 60 transfers the slider SL to the slider positioning member 50; and a positioning step of positioning the slider SL by the slider positioning member 50 at a position to be attached to the fastener stringer C2.

In the above-described conveying step, the slider SL is conveyed in a state where the tab P is suspended, and in the above-described positioning step, the insertion claw 55a of the insertion portion 55 is inserted into the tab attachment hole Pa of the tab P. Further, the insertion claw 55a of the insertion portion 55 moves in the tab attaching hole Pa after being inserted into the tab attaching hole Pa, presses the inner peripheral edge of the tab attaching hole Pa, and pulls down the tab P. In the above-described carrying step, the carrying speed of the slider SL is controlled so that the swing angle of the tab P in the vertical plane along the slider carrying direction becomes equal to or smaller than the insertion allowance angle α allowing the insertion pawl 55a to be inserted into the tab attaching hole Pa.

As described above, according to the slide fastener manufacturing apparatus 10 of the present embodiment, the control portion 68 that controls the driving of the servo motor 64 controls the moving speed of the pull transport member 60 so that the swing angle of the pull tab P in the vertical plane along the slider transporting direction becomes equal to or smaller than the insertion allowable angle α that allows the insertion portion 55 to be inserted into the tab attaching hole Pa, and therefore, the slider SL can be transported quickly while suppressing the swing angle of the pull tab P. Thus, after the slider SL is conveyed to the 2 nd position G2, the insertion portion 55 can be inserted into the tab attaching hole Pa without waiting for the swing of the tab P to be leveled, so that the time required for one cycle for attaching the slider SL to the fastener stringer C2 can be shortened, and the productivity of the fastener manufacturing apparatus 10 can be further improved.

Further, according to the method of manufacturing a slide fastener of the present embodiment, in the slider SL conveying step, the conveying speed of the slider SL is controlled so that the swing angle of the tab P in the vertical plane along the slider conveying direction becomes equal to or smaller than the insertion allowance angle α allowing the insertion portion 55 to be inserted into the tab attaching hole Pa, and therefore, the slider SL can be quickly conveyed while suppressing the swing angle of the tab P. Thus, after the slider SL is conveyed to the slider positioning member 50, the insertion portion 55 can be inserted into the tab attaching hole Pa without waiting for the swing of the tab P to be repeated, so that the time required for one cycle for attaching the slider SL to the fastener stringer C2 can be shortened, and the productivity of the slide fastener SF can be improved. Further, the insertion portion 55 inserted into the tab attaching hole Pa pushes the inner peripheral edge of the tab attaching hole Pa of the tab P in the swing state to pull down the tab P, so that the swing of the tab P can be reliably stopped.

The tab P may be the tab Ps shown in fig. 8A and 8B. The tab Ps includes a connection part Pc attached to the tab attachment part D1, and a grip part Pg attached to the connection part Pc. The connection portion Pc has a tab attachment hole Pa and a connection hole Pb for attaching the grip portion Pg. In the present invention, even if the tab Ps whose swing angle tends to increase, the swing angle of the tab Ps can be set to the insertion allowable angle α or less by controlling the moving speed of the slider SL according to the speed curve shown in fig. 7.

The present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the scope of the present invention.

For example, in the above embodiment, in the control of the moving speed of the slider conveying member, both the acceleration at the time of starting the movement from the 1 st position and the deceleration at the time of stopping at the 2 nd position are controlled, but either one may be controlled.

Further, the slide fastener manufacturing apparatus of the above embodiment is provided with one transfer device, but may be provided with two or more transfer devices.

Further, the discharge device may be eliminated and the slide fastener may be discharged by the transfer device.
