For those skilled in the art, various embodiments and/or features can be combined without much explanation. Moreover, those skilled in the art can also understand the superposition effect of the combination. In principle, repeated explanations between the embodiments are omitted. The main purpose of the drawings is to describe the invention and is sometimes simplified for ease of drawing.

In the following description, the multiple features described for a zipper manufacturing method, assembly machine, unit and system can be understood as a combination of these features, and in addition can be understood as an individual feature independent of other features . An individual feature can be understood as an independent individual feature, not necessarily in combination with other features, but can also be understood as a combination with more than one other individual feature. For those skilled in the art, describing all the combinations of individual features will only make the description verbose and therefore omitted. Individual characteristics are expressed by expressions such as "certain circumstances". The individual features can be understood as not only effective for the manufacturing method, assembling machine, unit and system of the zipper disclosed in the drawings, but also a general feature common to other manufacturing methods, assembling machines, unit and system of other zipper.

The slider 5 shown in FIGS. 1 and 2 is used to open and close a pair of left and right zipper chain belts included in the zipper chain 2 as is known with reference to FIG. 3. The left and right zipper chain belts will be closed before the slider 5, and the left and right zipper chain belts will be opened when the slider 5 moves backward. Each fastener chain belt has a fastener chain cloth 3 and a fastener element 4 provided on the fastener chain cloth 3. The fastener chain fabric 3 is composed of a woven fabric or a knitted fabric, has a certain width, and extends long in one direction. The fastener stringer 3 has the 1st belt surface 3a and the 2nd belt surface 3b on the opposite side to the 1st belt surface 3a, and has thickness determined by these two surfaces. The fastener element 4 can be a spiral element, a resin element, a metal element, or other types of elements. The left and right fastener elements 4 are further engaged by the slider 5, and the engagement of the left and right fastener elements 4 is released by the slider 5 retreating.

The slider 5 has a slider body 6 and a pull tab 7. The slider body 6 can be made of metal. The handle 7 can be made of resin. The pull tab 7 is provided in the slider body 6 such that its posture can be maintained at an arbitrary angle between the inverted posture of the pull tab 7 relative to the slider body 6 and the inverted posture of the pull tab 7 relative to the slider body 6. In FIG. 2, the pull-tab 7 at the first position P1 is in an inverted posture, the pull-tab 7 at the second position P2 is in a lying posture lying forward, and the pull-tab 7 at the third position P3 is in lying downside down In the posture, the pull-tab 7 at the fourth position P4 is in the lying posture of falling forward obliquely upward, and the pull-tab 7 at the fifth position P5 is in the lying posture of lying backward obliquely upward. In this way, the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the inverted posture or any angle between the two inverted postures. Of course, the angle of the pull tab 7 can be changed according to the operation of humans and machines. The angle of the pull tab 7 is the angle θ formed by the pull tab 7 and a plane orthogonal to the extending direction of the column portion 62 of the slider body 6 as will be described later (see FIG. 2 ).

The pull tab 7 has a base end 74 held by the slider body 6 and a free end 75 on the opposite side of the base end 74. In some cases, the pull tab 7 is bent at at least one location between the base end 74 and the free end 75, which facilitates the pull tab 7 to use the shaft portion 71 as the free end 75 of the pull tab 7 is pushed The center rotates.

In some cases, the fastener chain fabric 3 has a belt main portion 31, a sprocket attachment portion 32, and a folded-back portion 33. The folded-back portion 33 is arranged between the belt main portion 31 and the sprocket attachment portion 32. Since the fastener chain 3 has the folded-back part 33, the area|region of the tape main part 31 which adjoins the folded-back part 33 overlaps with the element attachment part 32 up and down. The fastener element 4 is attached to the first belt surface 3 a of the element attachment portion 32. When the fastener element 4 is a spiral element, the fastener element 4 is sewn to the element attachment portion 32 with at least one thread.

In some cases, the slider body 6 has: a lower wing plate 61; a post portion 62, which is used to separate the left and right fastener elements 4 in the engaged state; an upper plate portion 63, which is combined with the upper end of the post portion 62; A pair of claw portions 64 for holding the shaft portion of the pull tab 7; a pair of side wall portions 65 provided on the left and right side edges of the lower wing plate 61; and a pair of flange portions 66 formed from the side wall portions 65 The upper end extends toward the upper plate portion 63. A pair of claw portions 64 are provided on the upper plate portion 63 and are provided along the front-rear direction. A pair of front openings are provided adjacent to the left and right sides of the column portion 62, and a rear opening is provided on the opposite side. Between the upper plate portion 63 and the flange portion 66, a slit through which the folded portion 33 of the fastener chain 3 passes is formed. The flange portion 66 is inserted between the belt main portion 31 and the fastener element mounting portion 32 of the fastener chain 3.

The fastener element 4 in the engaged state enters the slider body 6 through the rear opening of the slider body 6 and moves in the space between the left and right side wall portions 65. When the fastener element 4 in the engaged state reaches the post 62, the engagement is released by the post 62. Each fastener element 4 in the non-engaged state moves out of the slider body 6 through each front opening. In addition, the fastener element 4 moves in the space restricted by the lower flap 61 and the flange portion 66 in the up-down direction. When the slider 5 moves, the flange portion 66 of the slider body 6 is always covered by the belt main portion 31 of the fastener chain 3. When observing the first tape surface 3 a of the tape main portion 31, the tape main portion 31 of the fastener chain fabric 3 obstructs the visual recognition of the slider 5. Zipper 99 is therefore called "invisible zipper".

In some cases, the pull-tab 7 has a shaft portion 71, a pair of rod portions 72 extending from the shaft portion 71 in the longitudinal direction of the pull-tab 7, and a grip portion 73 held by a human hand. By holding the shaft portion 71 of the pull tab 7 to the claw portion 64 by one of the sliders 5, the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the inverted posture. For example, when assembling the slider 5, the shaft portion 71 of the pull tab 7 is arranged between the claw portions 64 before pressing, and then each claw portion 64 is pressed. The shaft portion 71 of the pull tab 7 is pressed between the pair of claw portions 64 and/or between the claw portion 64 and the mounting portion 63 a of the upper plate portion 63. By pressing the shaft portion 71 of the pull tab 7 in this way, the posture of the pull tab 7 can be maintained throughout the entire rotation range of the pull tab 7, and the pull tab 7 will not rotate due to gravity. The placing portion 63a of the upper plate portion 63 is a portion on which the shaft portion 71 of the pull tab 7 is placed. Additionally or alternatively, the claw portion 64 is sandwiched between the pair of bar portions 72, whereby the posture of the pull-tab 7 can be maintained at any angle between the inverted posture and the inverted posture. The grip 83 is provided with a symbol such as ABC. The logo can be recessed or protruding.

In some cases, the slider 7 is integrally formed on the slider body 6 based on insert molding. In this case, the posture of the pull-down blade 7 can also be maintained at any angle between the inverted posture and the inverted posture. In some cases, the shaft portion 71 of the pull tab 7 is divided into two parts, and the end of the shaft portion 71 of the pull tab 7 is pressed into the hole of the pull tab mounting portion of the slider body 6. In this case, the posture of the pull-down blade 7 can also be maintained at any angle between the inverted posture and the inverted posture. There are various specific forms for realizing that the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the inverted posture, and it should not be limited to the illustrated example.

Hereinafter, the method of manufacturing the slide fastener of the present invention will be described with reference to FIGS. 4 to 9. 4 is a schematic diagram showing a system 400 for manufacturing a zipper 99. FIG. 5 is a schematic step diagram showing a step of attaching the pull tab 7 to the slider body 6 supplied to the mounting box 115 of the assembling machine 100 and turning the pull tab 7 to an inverted posture. 6 is a schematic step diagram showing a step of turning the pull-tab 7 toward the inverted posture while the slider 5 supplied from the parts feeder 200 passes through the slide groove 602. FIG. 7 is a schematic diagram showing the alternative method of FIG. 6. FIG. 8 is a schematic step diagram showing steps performed in the device 300 for engaging the fastener element 4 with the slider body 6. FIG. 9 is a schematic step diagram showing steps performed in the device 300 for engaging the fastener element 4 and the slider body 6.

In the system 400, a first pull-tab operation step and a fastener element engagement step are performed. In the first pull-tab operation step, the pull-tab 7 of the slider 5 is rotated toward the inverted posture, and the slider 5 is pulled The tab 7 is provided on the slider body 6 in such a manner that its posture can be maintained at any angle between the inverted posture of the pull tab 7 relative to the slider body 6 and the inverted posture of the pull tab 7 relative to the slider body 6. In this fastener element engagement step, the fastener element 4 included in the fastener chain 2 and the slider 7 are rotated to the slider body 6 of the slider 5 on the inverted posture side. In some cases, the first pull tab operation step is performed earlier than the zipper element engagement step along the time axis, or the first pull tab operation step is performed at a position more upstream than the zipper element engagement step, or The first pull-tab operation step is performed in a device further upstream than the fastener element engagement step. The upstream described here is understood based on the manufacturing method of the slider 5 or the zipper 99. Engaging the fastener element 4 with the slider body 6 means inserting the fastener element 4 into the fastener element passage between the rear port and the front port of the slider body 6.

In the first pull-tab operation step, the pull-tab 7 is turned toward the inverted posture, and in this state, the fastener element 4 is engaged with the slider body 6. In this case, the restriction of the form of holding the slider 5 by the holder is relaxed, and/or the fastener element 4 and the slider body 6 of the slider 5 are smoothly engaged. Additionally or alternatively, when the slider 5 is a slider for an invisible zipper, interference between the fastener chain 3 and the pull tab 7 can be avoided or suppressed.

In some cases, the system 400 can include an assembling machine 100 for assembling the slider 5, a parts feeder 200 for storing and feeding the slider 5, and a mechanism for engaging the fastener element 4 with the slider body 6装置300。 The device 300. The first pull-tab operation step is performed at the station assigned to the assembling machine 100 for attaching the pull-tab 7 to the slider body 6. Additionally or alternatively, the first pull-tab operation step is performed when the slider 5 moves along the chute 602 connected to the parts feeder 200 for storing and feeding the slider 5. Turning the pull tab 7 toward the inverted posture can be performed by a human hand. In some cases, it is performed based on the operation of the first pushing member 501 provided in the assembly machine 100 or the second pushing member 502 provided along the chute 602.

Assuming that the first pull-tab operation step is performed N times, here, N is a natural number of 2 or more. For example, the first pull-tab operation step is performed at the station assigned to the assembling machine 100, and, in addition to this, is also performed when the slider 5 moves along the chute 602 connected to the component feeder 200. In this case, the probability of occurrence of poor adjustment related to the angle of the pull tab 7 can be reduced. It should be noted that the first pull-tab operation step can be additionally or alternatively performed on other devices.

With the first pull-tab operation step, the pull-tab 7 is set to a target angle within an angle range of 30° to 150°. The angle of the pull tab 7 is the angle θ formed by the pull tab 7 and a plane orthogonal to the extending direction of the column portion 62 of the slider body 6 (see FIG. 2 ). When the pull tab 7 is bent between the base end 74 and the free end 75, refer to the portion of the pull tab 7 extending between the bent portion closest to the base end 74 and the base end 74 for determination Angle of pull tab 7. In the illustrated example, the pull tab 7 has a bar portion 72 extending between the bent portion of the pull tab 7 and the base end 74 of the pull tab 7. The angle of the pull-tab 7 is represented by the angle θ formed by the rod portion 72 and a plane orthogonal to the extending direction of the column portion 62 of the slider body 6.

In the case where the plate portion 63 on the slider body 6 is disposed on a plane orthogonal to the extending direction of the column portion 62 of the slider body 6, the angle of the pull tab 7 is also formed by the pull tab 7 and the slider body 6 The angle θ formed by the plate portion 63 (or its upper surface) is represented. In the case where the flange portion 66 of the slider body 6 is arranged in a plane orthogonal to the extending direction of the column portion 62 of the slider body 6, the angle of the pull tab 7 is also caused by the protrusion of the pull tab 7 and the slider body 6 The angle θ formed by the edge portion 66 (or its upper surface) is represented. A plane orthogonal to the extending direction of the column portion 62 of the slider body 6 is parallel to the moving direction (that is, the front-rear direction) of the slider 5 for opening and closing the slide fastener. Therefore, the angle of the pull-tab 7 can also be understood as the angle formed by the front-rear direction and the extending direction of the pull-tab 7.

When the pull tab 7 with an angle of 90° is turned backward (toward the third position P3), the angle of the pull tab 7 is reduced, and when the pull tab 7 with an angle of 90° is turned (toward the second position P2) During rotation, the angle of the pull-tab 7 increases. In this case, the pull-tab 7 is set at a target angle within an angle range of 30° to 120°. In the second pull-tab operation step, the pull-tab 7 is promoted to fall backward. When the bent pull-tab 7 falls backward, the posture of the grip portion 73 extending between the bent portion of the pull-tab 7 and the free end 75 can be inclined backward and downward. Thereby, the volume when bundling a plurality of slide fasteners can be reduced.

In some cases, the assembling machine 100 has a plurality of stations S1 to S12, and can move the mounting box supplied to the slider body 6 between the stations S1 to S12. The multiple stations S1-S12 can be arranged in a straight line or a ring.

As shown in FIG. 5, the assembling machine 100 includes: a turntable 110 having a plurality of mounting boxes 115 to which the slider body 6 is supplied; and a first pushing member 501 positioned on the outer periphery of the turntable 110 for Turn the pull tab 7 toward the inverted position. The slider body 6 is supplied to the mounting box 115, and is positioned by side claws (not shown). As the turntable 110 rotates, the slider body 6 equipped with the mounting box 115 of the turntable 110 is supplied to the stations S1 to S8, and the processing assigned to the stations S1 to S8 is performed.

For example, at the station S1, the slider body 6 is supplied to the mounting box 115 (see (a) of FIG. 5 ). At the station S3, the slider 7 is supplied to the slider body 6 positioned at the mounting box 115. At station S4, check the presence or absence of pull tab 7 and its positive and negative. At the station S5, the claw portion 64 of the slider body 6 is pressed by the pressing member, and the pull tab 7 is attached to the slider body 6 (see (b) of FIG. 5). At station S6, the compression state is checked mechanically or based on images. At the station S7, the pull tab 7 rotates toward the inverted posture based on the movement of the first pushing member 501 (refer to (c) of FIG. 5).

In some cases, the first pushing member 501 travels straight toward the rotation center of the turntable 110, in other words, it travels straight radially inward based on the understanding of the stations S1 to S12 arranged in the circumferential direction. The angle of the pull-tab 7 can be set to the target angle based on the straight travel distance of the first push member 501. The first pushing member 501 can be fixed to the rod tip of the cylinder. In some cases, the pull-tab 7 collides with the stop member 601 to avoid or suppress the deviation of the angle of the pull-tab 7 (refer to (c) of FIG. 5). At the station S8, the slider 5 with the slider 7 attached to the slider body 6 is discharged. At station S9, it is checked whether the side claw used to fix the slider body 6 at a fixed position relative to the mounting box is missing. At station S11, it is confirmed that there is no slider body 6 in the mounting box.

The parts supplier 200 is a device for storing and supplying a group of sliders 5 assembled by the assembling machine 100. The component feeder 200 has a guide plate into which a slit of the slider body 6 can be inserted, and the slider body 6 can be conveyed along the guide plate by giving vibration to the guide plate. The slider 5 discharged from the parts feeder 200 is conveyed to the chute 602 and moves along the chute 602. In some cases, the sliding member 5 will move in the sliding groove 602 due to gravity. The slide groove 602 is an arbitrary cylinder that allows the slider 5 to slide, and can have a slit through which the pull tab 7 passes.

When the slider 5 moves along the chute 602 connected to the parts feeder 200 for storing and feeding the slider 5, the first pull-tab operation step can be performed in various forms. In some cases, a stop member 603 for stopping the slider 5 moving along the chute 602 due to gravity is provided, and the slider 7 of the slider 5 colliding with the stop member 603 is based on the action of the second pushing member 502 Turn towards the inverted position. The second pushing member 502 rotates by a predetermined angle based on the rotational force supplied from the driving source of the free motor, and sets the angle of the pull tab 7 to the target angle. After setting the angle of the pull-tab 7 to the target angle, the stop member 603 is operated to release the movement stop of the slider 5. In some cases, the second push member 502 rotates the pull tab 7 downward in the vertical direction, thereby ensuring that the slider 5 moves along the slide groove 602 (falls) before the second push member 502 returns to the original position . The slider 5 discharged from the chute 602 is held by the transfer holder 609. By rotating the delivery holder 609 by 90°, the lower wing 61 of the slider 5 is oriented in a horizontal direction orthogonal to the vertical direction. The combination of the chute 602 and the second pushing member 502 can be understood as a unit.

The angle of the pull-tab 7 set by the first push member 501 can be the same as or different from the angle of the pull-tab set by the second push member 502. In the case of FIG. 6, as in FIG. 5, the target angle of the pull tab 7 is 90°. In the case of FIG. 7, the target angle of the pull tab 7 is different from that of FIG. 5 and is smaller than 90°. Considering that the angle of the pull tab 7 in the parts feeder 200 may change after being discharged from the assembling machine 100, in some cases, the first push member 501 is used to relatively rotate the pull tab 7 relatively, and then, the second The pushing member 502 rotates the pull tab 7 relatively small.

As an option, the manufacturing method of the zipper further includes an inspection step in which the pull tab 7 rotated to the inverted posture side is photographed, and the mark provided on the pull tab 7 is checked based on the camera data and the pre-registered information. In some cases, the logo of the slider 7 of the slider 5 in the process of passing through the chute 602 is photographed. As shown in FIG. 6, an imaging unit 604 for photographing the slider 7 of the slider 5 moving along the slide 602 can be provided. The imaging unit 604 can be a CMOS camera. The mark provided on the pull tab 7 is checked based on the camera data acquired by the camera component 604 and the pre-registered information. For inspection, use a digital or analog calculator, or a computer. The information registered in advance can be stored in the memory of the computer. The memory can be the internal memory or external memory of the CPU. For example, the computer detects the edge line of a part of the mark based on the camera data, and determines whether the edge line is within the position range within the image registered as the pre-registered information. Or the computer detects the outline of the logo based on the camera data, calculates the degree of agreement with the outline registered as the pre-registered information, and compares the calculated degree of agreement with the threshold. The sliding groove 602 is located at or near the end of the supply path of the slide 5 between the parts feeder 200 and the device 300. Checking the mark of the pull tab 7 at this position can effectively prevent the slider 5 with the pull tab with the wrong mark attached to the fastener chain 2 from engaging.

As shown in FIG. 8, the step of engaging the zipper element can include the step of holding the slider 5 with the holder 605 and the slider 4 contained in the zipper chain 2 and the slider 5 held with the holder 605 The step of engaging the slider body 6. Various devices have been developed for the device for engaging the fastener element 4 and the slider body 6 of the slider 5. The zipper chain 2 can be pulled downstream in the chain conveying direction by a pair of left and right clamps (not shown) that sandwich the left and right pair of zipper chain cloths 3 of the zipper chain 2. The fastener element 4 in the meshed state enters the slider body 6 through the rear surface of the slider body 6, and then the interval between the pair of left and right clamps expands. Thereby, each fastener element 4 can move smoothly outside the slider body 6 via the front opening of the slider body 6. After pulling out the target length of the zipper chain 2 with a jig, the zipper chain 2 is cut.

As an option, the manufacturing method of the slide fastener further includes a second pull-tab operation step in which the pull-tab 7 of the slider 5 engaged with the fastener element 4 is turned toward the inverted posture. The second pull-tab operation step can be performed in the device 300 after the fastener element 4 and the slider 5 are engaged. As shown in FIG. 9, the second pull-tab operation step can be performed based on the operation of the third pushing member 503 that runs straight toward the belt surfaces 3 a, 3 b of the fastener chain 3 included in the fastener chain 2. The third pushing member 503 can be fixed to the rod tip of the cylinder.

The third pushing member 503 can have at least one guide surface 504 that rotates the tab 7 whose posture is close to the inverted posture gradually toward the inverted posture in accordance with the travel of the third push member 503. The guide surface 504 can be a surface inclined along the direction in which the zipper chain 2 is conveyed. In some cases, the third pushing member 503 can include a set of guide surfaces 504a, 504b inclined in opposite directions to each other, that is, inclined in a V shape. Thereby, the pull-tab 7 can fall down in any direction more reliably. In addition, it is also assumed that the second pull-tab operation step is performed manually. With the second pull-tab operation step, the pull-tab 7 is brought into a collapsed state, which can reduce the volume when a plurality of slide fasteners are bundled.

As shown in FIG. 10, a form in which the second push member 502 rotates the pull-tab 7 toward the inverted posture is also assumed. The second pushing member 502 linearly moves according to the power supplied from the driving source of the free motor, and rotates the pull-tab 7 toward the inverted posture. When the pull-tab 7 rotates to the target angle, the second pushing member 502 retreats. The second pushing member 502 can move in a horizontal direction orthogonal to the vertical direction, for example. Any guide member for guiding the operation of the second pushing member 502 can also be used at the same time. After setting the angle of the pull-tab 7 to the target angle, the stop member 603 is operated to release the movement stop of the slider 5. The second push member 502 rotates the pull-tab 7 downward in the vertical direction, thereby ensuring that the slider 5 moves (falls) along the slide groove 602 before the second push member 502 returns to the original position (that is, moves backward). The slider 5 discharged from the chute 602 is held by the transfer holder 609. By rotating the delivery holder 609 by 90°, the lower wing 61 of the slider 5 is oriented in a horizontal direction orthogonal to the vertical direction.
