Description

Lock release system and lock release method of slider

The present invention relates to a lock release system and a lock release method of a slider, and more particularly, to a lock function for a slider to be attached to a fastener chain in the process of continuously manufacturing a fastener based on a continuous fastener chain Release system and method.

In the case of serially mass-producing a slide fastener having a row of synthetic resin engaging elements (elements) based on a continuous fastener chain, the following processing steps are generally performed in order. That is, a step of forming a fastener chain by injection molding a synthetic resin element row on each opposing edge of a pair of left and right long fastener tapes; A step of removing to form a spacer; a step of attaching a reinforcing film to a region sandwiching a part of the spacer in the fastener chain; a step of perforating a part of the reinforcing film to form a perforated part; the step of injection molding an opening member; combination A step of opening a member; a step of cutting the fastener chain in the width direction at a position corresponding to the perforated portion; and a step of injection molding a top stopper.

As one type of sliders, sliders with a locking function are known. The locking function generally acts so as to prevent relative movement with respect to the slider element row by bringing the claws of the distal end of the locking member into contact with the element row arranged in the slider. The claws of the locking member are in the locked state or the unlocked state according to the posture and position of the pull tab with respect to the slider. Therefore, when the slider is of a type having a locking function, in the step of inserting the slider onto the above-described cut fastener unit, the slider needs to be inserted into the fastener unit in a state where the locking function is released.

Further, the present inventors have found a fastener stringer in which one side of the slider is inserted into one of a pair of left and right fastener stringers obtained by injection-molding element rows at each opposing edge before the step of assembling the opening tool. , and the production efficiency of the slide fastener can be improved by combining the opening tool while passing the element row of the left and right fastener stringers through the slider. At this time, it is necessary to release the locking function of the slider before combining the opening members.

As a technique for releasing the lock function of the slider, there is known a technique of releasing the lock by fixing the slider, hooking a hook in a loop hole of a handle attached to the slider, and moving the hook. In addition, International Publication No. 2019/003318 discloses a technique of releasing the lock by displacing the pull tab with respect to the fixed slider by the lock releasing portion.

However, since all of the above-mentioned locking function releasing techniques displace the handle, it may not be applied depending on the shape of the handle such as the size of the ring hole. In addition, neither technique is intended for a slider attached to a fastener chain, and if it is used in the manufacturing process of a fastener, dense and complicated adjustment is required, and it is considered that it is difficult to realize stable operation.

In the present invention, first, the slider attached to the continuous fastener chain in the process of moving to the upstream side in the conveying direction or the downstream side in the conveying direction is stopped at a predetermined position by the slider stop mechanism. The slider stop mechanism includes a control portion. For example, when the sensor detects the slider, the controller can stop the slider at a predetermined position by stopping the drive roller of the fastener chain. After the slider is stopped at the prescribed position, the slider is held by the pressing member. At this time, the posture of the slider is adjusted by the pressing member. Next, the pull tab stopper is brought into contact with or approached by the slider stopped at a predetermined position. The slider is displaced toward the upstream side in the conveying direction or toward the downstream side in the conveying direction by the pressing member. At this time, the pull-tab stopper restricts the displacement of the pull-tab with respect to the slider displaced by the pressing member. Thereby, the handle can be relatively displaced toward the lock release position with respect to the displaced slider, and the lock function can be released. In addition, normally, before the slider is displaced by the pressing member, the pull tab is located at the locked position, and the pull tab is relatively displaced from the locked position toward the unlocked position with respect to the slider displaced by the pressing member. The pull tab is in the unlocked position before the pressing member displaces the slider. Even in the latter case, the handle can be reliably arranged at the unlocked position by relative displacement with respect to the slider.

In general, the locking function of the slider acts so as to prevent the relative movement of the slider with respect to the element row by bringing the claw (see FIG. 27 ) at the tip of the locking member into contact with the element row in the slider.

In addition, the relative movement of the slider 3 can be moved to a position in front of the top stopper 22 shown in FIG. 17 instead of being brought into contact with the top stopper 22 . When the slider 3 is positioned at the upper stopper restricting position as shown in FIG. 16 , most of the upper stopper 22 is concealed in the slider 3 . A slider pull-down mechanism that pulls down the slider 3 located at the top stopper restriction position may be additionally provided. The slider pull-down mechanism pulls down the slider 3 located at the upper stopper restricting position to expose the upper stopper 22 . Whether or not the exposed top stopper 22 is normally formed can be automatically checked by an inspection mechanism using an image obtained by an imaging unit such as a camera, or an inspection mechanism using a contact or non-contact sensor. Alternatively, it can also be checked by the operator's eyes whether or not it is formed normally. The inspection by visual inspection may be performed after the fastener chain 10 is cut into the slide fastener 30 by the cutting mechanism 133 . In addition, the inspection object of the above-mentioned inspection function may include not only the upper stopper 22 but also the opening tool ( 20 , 21 ) or the lower stopper. When the above-mentioned slider 3 after combining the opening tools ( 20 , 21 ) is relatively moved to the position (see FIG. 17 ) in front of the top stopper 22 , the above-mentioned inspection of the top stopper 22 can be performed without additional pulling. The head pull-down mechanism is performed in a later step. Next, the fastener chain 10 is cut|disconnected at the site|part corresponding to the perforated part 13 by the cutting mechanism 133, and several slide fasteners 30 are obtained. For the sake of convenience, the slider 3 in a state of being pulled down from the upper stopper restricting position by the slider pull-down mechanism is shown in FIG. 17 showing the slide fastener 30 after cutting, but after the slider 3 is pulled down, the slider 3 is pulled down. The mechanism 133 is cut off. By cutting from the perforated part 13, the reinforcement film part 12a which is a part of the reinforcement film 12 remains in the upper end part of the left and right fastener stringers 1a, 1a of the slide fastener 30, and remains in the lower end part of the fastener stringer 1a, 1a There is a reinforcing film portion 12 b as a part of the reinforcing film 12 .

Next, some embodiments of the lock release system and the lock release method of the slider according to the present invention will be described based on the drawings, but the present invention is not limited to such embodiments. While stopping the slider 3 at a predetermined position S (see FIG. 20 ) and passing the element row 2 of the left and right fastener stringers 1 a and 1 a through the stopped slider 3 , the chain of the above-mentioned third device 130 is The combination mechanism 131 performs combination of the socket body 20 with the seat bar and the plunger 21 . Therefore, when the slider 3 has a locking function with respect to the element row 2, it is necessary to release the locking function of the slider 3 stopped at the predetermined position S. The locking function generally acts to prevent relative movement of the slider 3 with respect to the element row 2 by bringing the claw 5 (see FIG. 27 ) at the tip of the locking member into contact with the element row 2 in the slider 3 . Such a lock function becomes a lock state or a lock release state according to the positional situation including the attitude of the handle 4 attached to the slider 3 with respect to the slider 3 . That is, the handle 4 can acquire the lock position which makes the slider 3 exhibit the lock function, and the lock release position which releases the lock function. The lock release system and lock release method of the slider according to the present invention release the lock function of the slider 3 before the socket body 20 with the seat bar and the plunger 21 are combined by the chain combination mechanism 131 .

Hereinafter, the fastener stringer 1a passing through the left side of the slider 3 on one side of the fastener chain 10 is also referred to as "1st fastener stringer 1A", and the fastener stringer 1a on the right side is referred to as "2nd fastener stringer 1B" ". The socket body 20 with the seat bar is injection-molded on the first fastener stringer 1A, and the plunger 21 is injection-molded on the second fastener stringer 1B. 23, 26, etc., the slider 3 includes the above-mentioned locking function. Moreover, the slider 3 is provided with the upper blade 3b, the lower blade 3c, the semi-annular handle connection part 3d provided in the upper blade 3b, and the handle 4 attached to the handle connection part 3d. In addition, illustration of the handle 4 is abbreviate|omitted in FIGS. 7-17. The handle 4 has a ring hole 4 a (see FIG. 26 ) on the proximal end side (the side opposite to the free end), and the handle connection portion 3 d penetrates through the ring hole 4 a to connect the handle 4 and the slider 3 . The handle 4 is rotatable around a proximal end shaft portion 4b (refer to FIG. 26 ) that defines the proximal end side of the ring hole 4a. The upper and lower wings 3b and 3c have left and right inclined side portions 3e (see FIGS. 24 , 28 , etc.) whose left and right widths gradually increase toward the upstream side in the conveying direction, that is, the shoulder ( 3 a ) side. A pair of left and right pressing members 190 to be described later are set to act on the left and right inclined side portions 3 e of the upper blade 3 b of the slider 3 . The slider 3 pierced through the first fastener tape 1A on one side moves to the upstream or downstream of the conveying direction in the following posture: the upper flap 3b faces downward, the lower flap 3c faces upward, and the left and right shoulders (3a) face the conveyance The direction upstream side and the rear port face the downstream side in the conveying direction. Therefore, the pull tab 4 comes under the fastener chain 10 .

18 is an explanatory side view showing the timing at which the slider 3 of the fastener chain 10 is detected by the second sensor 152 in the process of moving downstream in the conveying direction in the substantially horizontal conveying path. The 2nd sensor 152 transmits the detection signal of the slider 3 to the control part 150 (refer FIG. 21), and the control part 150 reversely rotates the driving roller 142 which rotated forwardly through the roller drive part 142a (refer FIG. 21). Thereby, the fastener chain 10 starts to move upstream in the conveyance direction. At this time, the slider stopper 160 , the slider support member 170 , and the handle stopper 180 , which will be described later, are located at the lower initial positions. FIG. 19 is a plan view showing the fastener chain 10 at the time of FIG. 18 , and shows a pair of left and right pressing members 190 located at the initial position. In addition, in FIG.19, FIG.22, FIG.24, FIG.28 and FIG.34, illustration of the element row 2 is abbreviate|omitted. At the timing of FIG. 19 , the pair of left and right pressing members 190 are in the initial positions away from each other. The right and left pressing members 190 are located at a position corresponding to a predetermined position S (refer to FIG. 20 ) at which the slider 3 is stopped in the conveying direction, strictly speaking, at a position corresponding to the left and right inclined side portions 3 e of the slider 3 stopped at the predetermined position S. position (corresponding to the inclined side). Each pressing member 190 includes a support rod 191 and a disc-shaped pressing portion 192 connected to a shaft portion on one end side of the support rod 191 . The other end of the support rod 191 is connected to the pressing member driving part 190a (see FIG. 21 ). At the positions corresponding to the above-mentioned inclined side portions in the conveying direction, the left and right pressing members 190 can be moved to the following positions: an initial position where the pressing portions 192 are separated from each other; The holding position (see FIG. 24 ) where the inclined side portions 3e of the slider 3 are in contact; and the pressing position where the left and right pressing portions 192 are slightly closer to each other from the holding position and press the inclined side portions 3e of the slider 3 (see FIG. 28 ). The left and right pressing members 190 can be brought into contact with the left and right inclined side portions 3 e of the slider 3 stopped at the predetermined position S at the holding position to adjust the posture of the slider 3 . Moreover, the right-and-left pressing member 190 can displace the slider 3 to the upstream side of a conveyance direction by pressing the left-right inclined side part 3e of the slider 3 by being displaced from a holding position to a pressing position.

20 : is an explanatory side view which shows the timing at which the slider 3 of the fastener chain 10 in the process of moving upstream in the conveyance direction in the conveyance path is stopped at the predetermined position S by the slider stop mechanism. FIG. 21 is a block diagram showing a control structure in the lock release system of the present invention. In FIGS. 18 and 20 , since the fastener chain 10 moves in a state where the plunger 21 of the second fastener stringer 1B is placed on the socket body 20 with the seat bar of the first fastener stringer 1A, Therefore, the second fastener stringer 1B is partially displaced upward with respect to the first fastener stringer 1A. Reference numeral 153 in FIGS. 18 and 20 is a plunger guide member constituting a part of the combination mechanism 131 . The plunger guide member 153 is for guiding the plunger 21 of the second fastener stringer 1B to the shoulder of the non-unilateral penetrating side (the side where the slider 3 is not attached) of the slider 3 stopped at the predetermined position S. Member of the front guide. Reference numeral 154 in FIGS. 18 and 20 is a movement guide for guiding the movement of the fastener chain 10 . The first sensor 151 is built in the plunger guide member 153 . When the first sensor 151 detects the slider 3 approaching the predetermined position S, it transmits a detection signal to the control part 150, and the control part 150 produces|generates the following operation|movement.

The control part 150 stops the rotation of the drive roller 142 via the roller drive part 142a. Thereby, the movement to the upstream side of the conveyance direction of the fastener chain 10 stops, and the slider 3 stops at the predetermined position S (step A). Therefore, it can be said that the 1st sensor 151, the control part 150, the roller drive part 142a, and the drive roller 142 comprise a slider stop mechanism. Moreover, the control part 150 moves the slider stopper 160 which was previously located in the downward initial position to the upper operating position via the slider stopper driving part 160a. The slider stopper 160 at the operating position restricts the slider 3 stopped at the predetermined position S from moving to the upstream side in the conveying direction. In addition, the slider 3 may be stopped at the predetermined position S by the slider stopper 160 . The slider stopper 160 can also be said to be a constituent part of the slider stop mechanism. Furthermore, the control part 150 moves the slider support member 170 which was previously located in the downward initial position to the upper operation position via the slider support member drive part 170a. As shown in FIG. 18, the slider support member 170 has a substantially horizontal slider support surface 171 on the upstream side of the conveyance direction, and a handle support surface 172 inclined downward from the slider support surface 171 to the downstream side in the conveyance direction. The slider support surface 171 of the slider support member 170 at the operating position functions to support the slider 3 at the predetermined position S together with the aforementioned pair of left and right pressing members 190 to adjust the posture of the slider 3 . Therefore, the slider support member 170 and the pressing member 190 constitute a posture adjustment mechanism. The handle support surface 172 of the slider support member 170 at the operating position shifts the handle 4 attached to the slider 3 to the downstream side in the conveying direction with respect to the slider 3, and the handle 4 moves downstream in the conveying direction. Side and downward inclined state support. Since the handle 4 is shifted to the downstream side in the conveying direction with respect to the slider 3 located at the predetermined position S, the handle stopper 180 described later does not sandwich the handle 4 between the handle stopper 180 and the slider 3 . between. Moreover, the handle 4 supported by the handle support surface 172 of the slider support member 170 is located in the lock position which makes the slider 3 exhibit a lock function. Further, the control unit 150 moves the left and right pressing members 190 from the initial position (see FIGS. 19 and 22 ) to the holding position (see FIG. 24 ) via the pressing member driving unit 190 a. At the moment of FIG. 20 , the pull tab stopper 180 is still in the initial position below. In this embodiment, the handle stopper 180 is arrange|positioned between the slider stopper 160 and the slider support member 170 in the conveyance direction.

FIG. 22 is a plan view of the fastener chain 10 corresponding to FIG. 20 when the slider 3 is stopped at the predetermined position S, and is shown by cutting. FIG. 23 is a front explanatory view showing the slider 3 and the left and right pressing members 190 at the time of FIG. 22 , and the illustration of the fastener chain 10 is omitted. At the timing of FIGS. 22 and 23 , the control unit 150 starts the movement of the left and right pressing members 190 from the initial position to the holding position. FIG. 24 is a plan view of the fastener chain 10 when the left and right pressing members 190 are moved to the holding position, which is a cutaway plan view. At the holding position, the pressing portion 192 of each pressing member 190 contacts the inclined side portion 3e of the upper flap 3b below the slider 3 with a weak force to adjust the posture of the slider 3 (step D). After moving the left and right pressing members 190 from the initial position to the holding position, the control part 150 raises the handle stopper 180 previously located at the lower initial position to the upper operating position via the handle stopper drive part 180a. Thereby, the handle stopper 180 contacts or approaches the slider 3 in the predetermined position S (step B) (refer FIG. 26). After that, the control part 150 returns the slider stopper 160 and the slider support member 170 which are located in the operating position to the initial position below, respectively.

FIG. 25 is a perspective view of the pull tab stopper 180 . FIG. 26 is a perspective view showing a state in which the handle stopper 180 at the operating position is in contact with the slider 3 . Fig. 27 is a side explanatory view of Fig. 26, in which only the proximal end shaft portion 4b of the handle 4 is shown. The pull-tab stopper 180 includes two left and right leg portions 181 protruding upward, and a concave portion 182 that is recessed downward relative to the two leg portions 181 . The concave portion 182 is a space open upward and toward the downstream side in the conveying direction and the upstream side in the conveying direction. 26 and 27 , the upper surfaces of the two leg portions 181 of the pull tab stopper 180 at the operating position are in contact with the upper wing plate 3 b of the slider 3 . The upper surfaces of the two legs 181 may be close to the upper wing plate 3b. As described above, since the handle support surface 172 of the slider support member 170 deviates the handle 4 to the downstream side (right side in FIG. 27 ) in the conveying direction, the leg portion 181 of the handle stopper 180 does not hold the handle 4 . It is sandwiched between the leg portion 181 and the upper wing plate 3 b of the slider 3 . Thereby, the handle 4 is arrange|positioned at the conveyance direction downstream side rather than the handle stopper 180 in an operating position. In FIG. 26 which shows the time of applying the pull-tab stopper 180 to the slider 3, the pull-tab 4 shown so that it may be raised substantially horizontally is located in a locked position. However, the handle 4 may be located in the unlocking position at the timing of FIG. 26 . Moreover, the handle stopper 180 in the operating position partially accommodates the handle connection part 3d of the slider 3 in the recessed part 182. In other words, the handle stopper 180 avoids the handle connection part 3d by the recessed part 182, and takes an operating position. The recessed portion 182 allows passage of the handle connection portion 3d of the slider 3 displaced to the upstream side in the conveyance direction (left side in Fig. 27 ) from the state of FIGS. 26 and 27 , but does not allow the handle 4 to move to the upstream side in the conveyance direction. bit. That is, the handle stopper 180 in an operating position allows the displacement of the slider 3 to the upstream side of the conveyance direction, but restricts the displacement of the handle 4 to the upstream side of the conveyance direction.

FIG. 28 is a plan view of the fastener chain 10 when the left and right pressing members 190 are moved from the holding position to the pressing position, which is cut out and shown. When the left and right pressing members 190 are moved to the pressing positions, the pressing portions 192 of the respective pressing members 190 press the left and right inclined side portions 3 e of the slider 3 . Thereby, the inclined side part 3e of the slider 3 moves with respect to the peripheral side surface 192a (refer to FIG. 23 ) of each pressing part 192 , whereby the slider 3 is displaced to the upstream side (the left side in FIG. 28 ) in the conveying direction (step C) . FIG. 29 is a side view showing a state in which the slider 3 is displaced to the upstream side in the conveying direction by the pressing member 190 . FIG. 30 is an explanatory side view similar to FIG. 27 in which a part of FIG. 29 is enlarged. The left and right pressing members 190 press the inclined side portion 3e of the slider 3 at the pressing position, so that the slider 3 is moved from the position shown in FIG. 27 to the position shown in FIGS. ) is displaced, and the pull tab stopper 180 remains in a stationary state at this time. The handle stopper 180 in a stationary state restricts the displacement to the upstream side of the conveyance direction of the handle 4 following the slider 3 displaced to the upstream side in the conveyance direction, and makes the handle in the handle connection portion 3d of the slider 3 . As shown in FIG. 29 , the position of the proximal end shaft portion 4b of the handle 4 is relatively displaced toward the downstream end in the conveyance direction or a position in the vicinity thereof, that is, toward the unlocked position. Thereby, the claw 5 shown in FIG. 27 is retracted, and the locking function of the slider 3 is released.

31-33 is a side explanatory drawing which shows embodiment which includes the modification of a handle stopper and a slider support member. In addition, in FIGS. 31-33, the same code|symbol is attached to the structure common to embodiment described based on FIGS. 18-30, and description is abbreviate|omitted. FIG. 31 shows the timing at which the slider stopper 160 and the slider support member 173 are raised to the operating position while the slider 3 is stopped at the predetermined position S by the slider stop mechanism (step A). At this time, the pull tab stopper 183 is in the initial position below. In this embodiment, the slider support member 173 is arranged between the slider stopper 160 and the handle stopper 183, and the handle stopper 183 is adjacent to the slider support member 173 on the downstream side in the conveyance direction. configuration. The pull-tab stopper 183 has a tip end portion 183 a that is inserted into the annular hole 4 a (refer to FIG. 26 ) of the pull-tab 4 at the operating position. The slider support member 173 is provided with the recessed part (not shown) which can partially accommodate the handle connection part 3d of the slider 3 in an operating position. The pull tab 4 is sandwiched between the slider support member 173 at the operating position and the upper wing plate 3 b of the slider 3 . Thereby, the handle 4 is lifted up substantially horizontally. The slider support member 173 at the operating position is an attitude adjustment mechanism that can adjust the attitude of the slider 3 via the handle 4 . Next, as shown in FIG. 32, the pull-tab stopper 183 is raised to an operating position. Thereby, the front-end|tip part 183a of the handle stopper 183 is inserted in the ring hole 4a of the handle 4. As shown in FIG. In addition, it can be said that the pull tab stopper 183 moved to the operation position is close to the slider 3 at the predetermined position S (step B). In addition, just before the timing of FIG. 32 , the left and right pressing members 190 come to the holding position, and the posture of the slider 3 is adjusted (step D). Next, when the left and right pressing members 190 are moved from the holding position to the pressing position, as shown in FIG. 33 , the slider 3 is displaced to the upstream side in the conveying direction (step C). At this time, the handle 4 is regulated by the handle stopper 183 from its displacement to the upstream side in the conveyance direction, and is displaced to the downstream side in the conveyance direction relative to the slider 3 . Thereby, the handle 4 is located in a lock release position, and the lock function of the slider 3 is released. Furthermore, as shown in FIG. 33 , just before the left and right pressing members 190 move to the pressing position, the slider stopper 160 and the slider support member 173 return to the initial positions.

FIG. 34 is a plan view similar to FIG. 24 showing a modification of the pressing member. The pressing member 193 of FIG. 34 has a pressing portion 194 having a hemispherical shape on the side which is in contact with the left and right inclined side portions 3 e of the slider 3 . Such a pressing part 194 also acts on the left-right inclined side part 3e of the slider 3 similarly to the above-mentioned disc-shaped pressing part 192, and can displace the slider 3 to the upstream side in the conveyance direction.
