One or more embodiments in the disclosure and each feature included in the embodiments are not independent of each other. For those skilled in the art, various embodiments and/or various features can be combined without excessive description. Moreover, those skilled in the art can also understand the superposition effect of the combination. In principle, overlapping descriptions 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, a plurality of features described for a certain slide fastener manufacturing method, assembling machine, unit and system can be understood as a combination of these features, and can also be understood as individual features independent of other features. . An individual feature can be understood as an independent individual feature, not necessarily in combination with other features, but also as a combination with more than one other individual feature. For those skilled in the art, describing all combinations of individual features would only make the description redundant and is therefore omitted. Individual features are indicated by the expression "in some cases". Individual features can be understood as general features that are not only valid for the manufacturing method, assembling machine, unit, and system of slide fasteners such as those disclosed in the drawings, but are also common to other various slide fastener manufacturing methods, assembling machines, units, and systems.

The slider 5 shown in FIGS. 1 and 2 is used to open and close a pair of left and right fastener element tapes included in the fastener stringer 2 as can be seen with reference to FIG. 3 . The left and right fastener element tapes are closed by the advance of the slider 5 , and the left and right fastener element tapes are opened by the backward movement of the slider 5 . Each fastener element tape has a fastener tape 3 and a fastener element 4 provided in the fastener tape 3 . The fastener tape 3 is made of woven fabric or knitted fabric, has a certain width, and extends long in one direction. The fastener tape 3 has a first tape surface 3a and a second tape surface 3b on the opposite side to the first tape surface 3a, and has a thickness determined by these two surfaces. The fastener element 4 can be a helical element, a resin element, a metal element, or other types of elements. The fastener elements 4 on the left and right are engaged by the advance of the slider 5 , and the engagement of the fastener elements 4 on the left and right is released by the retreat of the slider 5 .

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 handle 7 is provided in the slider main body 6 so that the attitude|position can maintain the arbitrary angle between the fall attitude|position which the handle 7 falls down with respect to the slider main body 6, and the inversion attitude|position which the handle 7 reverses with respect to the slider main body 6. In FIG. 2, the handle 7 at the 1st position P1 is in the inverted posture, the handle 7 at the second position P2 is in the collapsed posture of falling forward, and the handle 7 at the third position P3 is the collapsed posture of falling backward. As for the posture, the handle 7 at the fourth position P4 is in a lodging posture in which the handle 7 at the 4th position P4 is slumped forward obliquely upward, and the handle 7 at the fifth position P5 is in a lodging posture in which the handle 7 at the 5th position P5 loaves backward obliquely upward. In this way, the posture of the handle 7 can be maintained at an arbitrary angle between the lying posture and the inverted posture, or an arbitrary angle between the two lying postures. Of course, the angle of the handle 7 can be changed according to the operation of a person or a machine. The angle of the handle 7 is the angle (theta) which the handle 7 makes with the plane orthogonal to the extending direction of the column part 62 of the slider main body 6 so that it may mention later (refer FIG. 2).

The handle 7 has a base end portion 74 held by the slider body 6 and a free end portion 75 on the opposite side to the base end portion 74 . In some cases, the pull-tab 7 is bent at at least one part between the base end portion 74 and the free end portion 75, which facilitates the pull-tab 7 to take the shaft portion 71 as the axis portion 71 when the free end portion 75 of the pull-tab 7 is pressed. Center turns.

In some cases, the fastener tape 3 has a tape main portion 31 , an element attaching portion 32 , and a folded-back portion 33 . The turn-back portion 33 is arranged between the belt main portion 31 and the element attaching portion 32 . Since the fastener tape 3 has the folded-back part 33, the area|region adjacent to the folded-back part 33 of the tape main part 31 and the element attachment part 32 are overlapped up and down. The fastener element 4 is attached to the 1st tape surface 3a of the element attachment part 32. As shown in FIG. 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 main body 6 includes a lower wing plate 61 , a column portion 62 for separating the left and right fastener elements 4 in an engaged state, and an upper plate portion 63 coupled to the upper end of the column portion 62 . A pair of claw portions 64 for holding the shaft portion of the handle 7; a pair of side wall portions 65 provided on the left and right side edge portions of the lower wing plate 61; and a pair of flange portions 66 from each The upper end of the side wall portion 65 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 ports are provided adjacent to the left and right sides of the column portion 62, and a rear port is provided on the opposite side. A slit through which the folded-back portion 33 of the fastener tape 3 passes is formed between the upper plate portion 63 and the flange portion 66 . The flange portion 66 is inserted between the tape main portion 31 of the fastener tape 3 and the element attaching portion 32 .

The fastener element 4 in the meshed state enters the slider main body 6 through the rear opening of the slider main body 6 and moves in the space between the left and right side wall parts 65 . When the fastener element 4 in the meshed state reaches the column portion 62 , the meshing is released by the column portion 62 . Each fastener element 4 in a disengaged state moves to the outside of the slider main body 6 via each front opening. Moreover, the fastener element 4 moves in the space restricted by the lower blade 61 and the flange part 66 in the up-down direction. When the slider 5 moves, the flange part 66 of the slider main body 6 is always covered with the tape main part 31 of the fastener tape 3 . When the first tape surface 3 a of the tape main portion 31 is observed, the tape main portion 31 of the fastener tape 3 obstructs the visual recognition of the slider 5 . The zipper 99 is therefore referred to as an "invisible zipper".

In some cases, the handle 7 includes a shaft portion 71 , a pair of rod portions 72 extending from the shaft portion 71 in the longitudinal direction of the handle 7 , and a grip portion 73 held by a human hand. By holding the shaft portion 71 of the handle 7 by the pair of claw portions 64 of the slider 5 , the posture of the handle 7 can be maintained at an arbitrary angle between the lying posture and the inverted posture. For example, when the slider 5 is assembled, the shaft portion 71 of the handle 7 is arranged between the claw portions 64 before caulking, and then each claw portion 64 is caulked. The shaft portion 71 of the handle 7 is pressed between the pair of claw portions 64 and/or between the claw portion 64 and the placement portion 63 a of the upper plate portion 63 . By pressing the axial part 71 of the handle 7 in this way, the attitude|position of the handle 7 can be maintained in the whole rotation range of the handle 7, and the handle 7 does not rotate by gravity. The placement portion 63a of the upper plate portion 63 is a portion on which the shaft portion 71 of the handle 7 is placed. Additionally or alternatively, the claw portion 64 is sandwiched between the pair of rod portions 72 , whereby the posture of the handle 7 can be maintained at any angle between the reclined posture and the inverted posture. A mark such as ABC is provided on the grip portion 83 . The logo can be recessed or raised.

In some cases, the pull tab 7 is integrally formed with the slider body 6 based on insert molding. Even in this case, the posture of the pull tab 7 can be maintained at any angle between the lying posture and the inverted posture. In some cases, the axial part 71 of the handle 7 is divided into two parts, and the edge part of the axial part 71 of the handle 7 is press-fitted into the hole of the handle attachment part of the slider main body 6. Even in this case, the posture of the pull tab 7 can be maintained at any angle between the lying posture and the inverted posture. The specific form which realizes that the posture of the handle 7 can be maintained at an arbitrary angle between the lying posture and the inverted posture is various, and should not be limited to the illustrated example.

Hereinafter, the manufacturing method of the slide fastener of the present disclosure will be described with reference to FIGS. 4 to 9 . FIG. 4 is a schematic diagram showing a system 400 for manufacturing the slide fastener 99 . 5 : is a schematic process figure which shows the process of attaching the handle 7 to the slider main body 6 supplied to the attachment box (Japanese: セットボックス) 115 supplied to the assembly machine 100, and turning the handle 7 to an inverted posture. 6 : is a schematic process figure which shows the process of turning the handle 7 to an inversion attitude|position in the process in which the slider 5 supplied from the parts feeder 200 passes the chute (Japanese: シュート) 602. FIG. 7 is a schematic diagram showing an alternative method of FIG. 6 . 8 : is a schematic process figure which shows the process performed by the apparatus 300 which engages the fastener element 4 and the slider main body 6. FIG. 9 : is a schematic process figure which shows the process performed by the apparatus 300 which engages the fastener element 4 and the slider main body 6. FIG.

In the system 400, the 1st handle operation process and the fastener element engagement process are performed, in this 1st handle operation process, the handle 7 of the slider 5 is turned toward the inverted posture, and the slider 5 is pulled The sheet|seat 7 is provided in the slider main body 6 so that the attitude|position can maintain the arbitrary angle between the fall-down attitude|position in which the handle|steering-wheel 7 falls with respect to the slider main body 6, and the inversion attitude|position of the handle-tab 7 with respect to the slider main-body 6 falls upside down. In this fastener element engagement process, the fastener element 4 contained in the fastener stringer 2 and the slider main body 6 of the slider 5 which turned the handle 7 to the inverted posture side are engaged. In some cases, the first handle operation step is performed earlier than the fastener element engaging step along the time axis, or the first handle operation step is performed at a position further upstream than the fastener element engaging step, or The 1st handle operation process is performed in the apparatus more upstream than the fastener element engagement process. The upstream mentioned here is understood based on the manufacturing method of the slider 5 or the slide fastener 99 . To engage the fastener element 4 with the slider main body 6 means to insert the fastener element 4 into the element passage between the rear opening and the front opening of the slider main body 6 .

In the 1st handle operation process, the handle 7 is rotated toward the inverted posture, and the fastener element 4 and the slider main body 6 are engaged in this state. In this case, the restriction of the form holding the slider 5 by the holder is eased, and/or smooth engagement of the fastener element 4 and the slider main body 6 of the slider 5 is promoted. Additionally or alternatively, when the slider 5 is a slider for a hidden slide fastener, interference between the fastener tape 3 and the handle 7 can be avoided or suppressed.

In some cases, the system 400 can include an assembly machine 100 for assembling the slider 5 , a parts feeder 200 for storing and supplying the slider 5 , and a device for engaging the zipper elements 4 with the slider body 6 . Device 300 . The 1st handle operation process is performed in the station allocated to the assembly machine 100 for attaching the handle 7 to the slider main body 6. Additionally or alternatively, the first pull-tab operation process is performed when the slider 5 is moved along the chute 602 connected to the parts feeder 200 for storing and supplying the slider 5 . Rotation of the handle 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 .

It is assumed that the first pull-tab operation process is performed N times, and here, N is a natural number of 2 or more. For example, the 1st handle operation process is performed at the station allocated to the assembly machine 100, and, in addition to this, is performed when the slider 5 is moved along the chute 602 connected to the parts feeder 200. In such a case, it is possible to reduce the probability of occurrence of adjustment failure related to the angle of the handle 7 . It should be noted that the first pull tab operation process can be additionally or alternatively performed in another device.

Through the 1st handle operation process, the handle 7 is set to the target angle in the angle range of 30 degrees - 150 degrees. The angle of the handle 7 is an angle θ (refer to FIG. 2 ) formed by the handle 7 and a plane orthogonal to the extending direction of the column portion 62 of the slider body 6 . When the handle 7 is bent between the base end portion 74 and the free end portion 75 , a portion of the handle 7 extending between the bent portion closest to the base end portion 74 and the base end portion 74 is referred to for determination The angle of the pull tab 7. In the illustrated example, the handle 7 has a rod portion 72 extending between the curved portion of the handle 7 and the base end 74 of the handle 7 . The angle of the handle 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 .

When the upper plate portion 63 of the slider main body 6 is arranged on a plane perpendicular to the extending direction of the column portion 62 of the slider main body 6 , the angle of the handle 7 is also determined by the handle 7 and the upper plate of the slider main body 6 . The angle θ formed by the portion 63 (or its upper surface) is indicated. When the flange portion 66 of the slider main body 6 is arranged on a plane orthogonal to the extending direction of the column portion 62 of the slider main body 6 , the angle of the handle 7 is also determined by the flange portion of the slider main body 6 and the handle 7 . The angle θ formed by the portion 66 (or its upper surface) is indicated. The plane orthogonal to the extending direction of the column part 62 of the slider main body 6 is parallel to the moving direction (that is, the front-back direction) of the slider 5 for opening and closing the slide fastener. Therefore, the angle of the handle 7 can also be understood as an angle formed by the front-rear direction and the extending direction of the handle 7 .

When the handle 7 with an angle of 90° is rotated backward (toward the third position P3 ), the angle of the handle 7 is reduced, and when the handle 7 with an angle of 90° is turned forward (toward the second position P2 ) At the time of rotation, the angle of the handle 7 increases, and in this case, the handle 7 is set to the target angle in the angle range of 30 degrees - 120 degrees. In the second handle operation step, the pull tab 7 is urged to fall backward. When the handle 7 bent at one place falls backward, the grasping portion 73 extending between the curved portion of the handle 7 and the free end portion 75 can take a posture in which the grip portion 73 is inclined rearward and downward. Thereby, the volume at the time of bundling a plurality of slide fasteners can be reduced.

In some cases, the assembly machine 100 has a plurality of stations S1 to S12, and can move the mounting box supplied with the slider body 6 between the stations S1 to S12. The plurality of stations S1 to S12 can be arranged linearly or annularly.

As shown in FIG. 5 , the assembling machine 100 includes: a turntable 110 having a plurality of mounting boxes 115 to which the slider main body 6 is supplied; and a first pushing member 501 positioned on the outer periphery of the turntable 110 for Rotate the pull tab 7 toward the inverted posture. The slider main body 6 is supplied to the attachment box 115, and is positioned by the side claw (Japanese: サイドジョー) which is not shown. Along with the rotation of the turntable 110, the slider body 6 of the mounting box 115 provided in the turntable 110 is supplied to each of the stations S1 to S8, and the processing assigned to each of the stations S1 to S8 is performed.

For example, in the station S1, the slider main body 6 is supplied to the attachment box 115 (refer FIG.5(a)). At the station S3, the pull tab 7 is supplied to the slider main body 6 positioned in the attachment box 115. At the station S4, the presence or absence of the pull tab 7 and the positive and negative are checked. In the station S5, the claw part 64 of the slider main body 6 is caulked by the presser, and the handle 7 is attached to the slider main body 6 (refer FIG.5(b)). At station S6, the caulking state is checked mechanically or based on images. At the station S7, the handle 7 is rotated toward the inverted posture based on the operation of the first push member 501 (refer to FIG. 5( c )).

In some cases, the first pushing member 501 goes straight toward the rotation center of the turntable 110 , in other words, goes straight toward the radially inner side as understood from the stations S1 to S12 arranged in the circumferential direction. The angle of the handle 7 can be set to the target angle according to the straight travel distance of the 1st push member 501 . The first push 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, and a deviation of the angle of the pull-tab 7 is avoided or suppressed (refer FIG.5(c)). At the station S8, the slider 5 with the handle 7 attached to the slider main body 6 is discharged. At station S9, it is checked whether the side claws for fixing the slider body 6 in a fixed position with respect to the mounting box are missing. In the station S11, it is confirmed that the slider main body 6 does not exist in the mounting box.

The parts feeder 200 is a device for storing and feeding a set of sliders 5 assembled by the assembly machine 100 . The parts feeder 200 has a guide plate which can be inserted into the slit of the slider main body 6, and can convey the slider main body 6 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 slider 5 may move within the chute 602 due to gravity. The chute 602 is an arbitrary cylindrical body that allows the slider 5 to slide, and can have a slit through which the handle 7 is inserted.

When the slider 5 moves along the chute 602 connected to the parts feeder 200 for storing and supplying the slider 5, the 1st handle operation process 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 pull tab 7 of the slider 5 colliding with the stop member 603 is based on the operation of the second push member 502 Rotate toward a handstand. The second pushing member 502 is rotated by a predetermined angle according to a rotational force supplied from a driving source such as a motor, and the angle of the handle 7 is set to a target angle. After setting the angle of the handle 7 to the target angle, the stop member 603 is actuated, and the movement stop of the slider 5 is released. 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 (drops) along the chute 602 even before the second push member 502 returns to the original position. . The slider 5 discharged from the chute 602 is held by the handover holder 609 . The lower wing plate 61 of the slider 5 is oriented in the horizontal direction orthogonal to the vertical direction by rotating the transfer holder 609 by 90°. The combination of the chute 602 and the second push member 502 can be understood as a unit.

The angle of the handle 7 set by the 1st pushing member 501 can be the same as or different from the angle of the handle set by the 2nd pushing member 502. In the case of FIG. 6, similarly to FIG. 5, the target angle of the handle 7 is 90 degrees. In the case of FIG. 7, the target angle of the handle 7 is different from FIG. 5, and is smaller than 90 degrees. Considering that the angle of the pull tab 7 in the parts feeder 200 may change after being ejected from the assembly machine 100, in some cases, the pull tab 7 is relatively largely rotated by the first pusher 501, and then The second push member 502 rotates the handle 7 relatively small.

As an option, the manufacturing method of a slide fastener further includes an inspection process in which the handle 7 turned to the inverted posture side is photographed, and the mark provided on the handle 7 is inspected based on imaging data and pre-registered information. In some cases, the logo of the pull tab 7 of the slider 5 in the process of passing through the chute 602 is photographed. As shown in FIG. 6, the imaging part 604 for imaging|photographing the handle 7 of the slider 5 which moves along the chute 602 can be equipped. The imaging unit 604 can be a camera such as a CMOS. The flag provided in the handle 7 is checked based on the imaging data acquired by the imaging part 604, and pre-registration information. To check, use a digital or analog calculator, or a computer. The pre-registration information can be stored in the memory of the computer. The memory can be the CPU's internal memory or external memory. For example, the computer detects an edge line of a part of the mark from the imaging data, and determines whether or not the edge line is located within a position range in an image registered as pre-registered information. Alternatively, the computer detects the outline of the marker from the imaging data, calculates the degree of agreement with the outline registered as pre-registered information, and compares the calculated degree of agreement with a threshold value. The chute 602 is located at or near the end of the feed path of the slider 5 between the parts feeder 200 and the device 300 . By performing inspection of the flag of the handle 7 at this position, the slider 5 of the handle to which the false flag is attached can be effectively suppressed from engaging with the fastener stringer 2 .

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

As an option, the manufacturing method of a slide fastener further includes the 2nd handle operation process in which the handle 7 of the slider 5 which engages with the fastener element 4 is turned toward the fallen posture. The 2nd handle operation process can be performed after engaging the fastener element 4 and the slider 5 in the apparatus 300. As shown in FIG. 9, the 2nd handle operation process can be performed based on the operation|movement of the 3rd push member 503 which goes straight toward the tape surfaces 3a and 3b of the fastener tape 3 contained in the fastener stringer 2. The third push member 503 can be fixed to the rod tip of the cylinder.

The 3rd pushing member 503 can have at least one guide surface 504 which rotates the handle 7 whose attitude|position approaches an inverted position gradually in accordance with the advance of the 3rd pushing member 503 approaching a reclining position. The guide surface 504 can be a surface inclined along the direction in which the fastener stringer 2 is conveyed. In some cases, the third push member 503 may include a set of guide surfaces 504a and 504b that are inclined in opposite directions, that is, inclined in a V-shape. Thereby, the handle 7 can be made to fall down in any direction more reliably. In addition, it is also assumed that the second handle operation process is performed manually. By setting the handle 7 in a state where it is laid down by the second handle operation step, the volume at the time of bundling a plurality of slide fasteners can be reduced.

As shown in FIG. 10, the form in which the 2nd pushing member 502 turns the handle 7 toward an inverted posture is also assumed. The 2nd pushing member 502 moves linearly by the power supplied from the drive source such as a motor, and rotates the handle 7 toward an inverted posture. When the handle 7 is rotated to the target angle, the second push member 502 retreats. The second pushing member 502 is movable in the horizontal direction orthogonal to the vertical direction, for example. Arbitrary guide members for guiding the movement of the second push member 502 can also be used together. After setting the angle of the handle 7 to the target angle, the stop member 603 is actuated, and the movement stop of the slider 5 is released. The second push member 502 can ensure that the slider 5 moves (drops) along the chute 602 even before the second push member 502 returns to the original position (ie, moves backward) by turning the handle 7 downward in the vertical direction. The slider 5 discharged from the chute 602 is held by the handover holder 609 . The lower wing plate 61 of the slider 5 is oriented in the horizontal direction orthogonal to the vertical direction by rotating the transfer holder 609 by 90°.
