It is possible for a person skilled in the art to combine embodiments and/or features without undue explanation. Also, the person skilled in the art will be able to understand the additive effect of the combination. In principle, the overlapping description between the embodiments is omitted. The drawings are primarily intended to illustrate the invention and are sometimes simplified for ease of illustration.
In the following description, a plurality of features described for a certain method, assembling machine, unit and system for manufacturing a slide fastener can be understood as a combination of these features, and can be understood as individual features independent of other features. Individual features can be understood as individual features, not necessarily in combination with other features, but also in combination with more than one other individual feature. For those skilled in the art, the description of the combination of the individual features is only redundant and will be omitted. Individual features are indicated by the expression "some cases". Individual characteristics can be understood as common characteristics not only effective for the manufacturing method, assembling machine, unit and system of the slide fastener disclosed in the drawings, for example, but also commonly used for other various manufacturing methods, assembling machines, units and systems of the slide fastener.
The slider 5 shown in fig. 1 and 2 is used to open and close a pair of right and left fastener element tapes included in the fastener stringer 2 as can be seen from fig. 3. The left and right fastener element tapes are closed by the forward movement 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 fastener elements 4 provided on the fastener tape 3. The fastener tape 3 is made of a woven or knitted fabric, has a certain width, and extends long in one direction. The fastener tape 3 has a 1 st tape surface 3a and a 2 nd tape surface 3b on the opposite side of the 1 st tape surface 3a, and has a thickness determined by these two surfaces. The fastener element 4 may be a helical element, a resin element, a metal element, or another type of element. The left and right fastener elements 4 are engaged by the forward movement of the slider 5, and the engagement of the left and right fastener elements 4 is released by the backward movement of the slider 5.
The slider 5 has a slider body 6 and a pull tab 7. The slider body 6 may be made of metal. The tab 7 may be made of resin. The tab 7 is provided to the slider body 6 so that the posture thereof can be maintained at an arbitrary angle between a reversed posture in which the tab 7 is reversed with respect to the slider body 6 and a reversed posture in which the tab 7 is reversed with respect to the slider body 6. In fig. 2, the tab 7 at the 1 st position P1 is in an inverted posture, the tab 7 at the 2 nd position P2 is in a laid-down posture in which it is laid down forward, the tab 7 at the 3 rd position P3 is in a laid-down posture in which it is laid down backward, the tab 7 at the 4 th position P4 is in a laid-down posture in which it is laid down obliquely upward forward, and the tab 7 at the 5 th position P5 is in a laid-down posture in which it is laid down obliquely upward backward. Thus, the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the laid-down posture or at any angle between the two inverted postures. Of course, the angle of the tab 7 can be changed by human or mechanical operations. The angle of the pull tab 7 is an angle θ (see fig. 2) 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 described later.
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 least one portion between the base end portion 74 and the free end portion 75, and rotation of the pull tab 7 about the shaft portion 71 when the free end portion 75 of the pull tab 7 is pressed is promoted.
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 folded-back portion 33 is disposed between the belt main portion 31 and the element attaching portion 32. The fastener tape 3 has the folded back portion 33, and therefore a region of the tape main portion 31 adjacent to the folded back portion 33 vertically overlaps the element attaching portion 32. The fastener element 4 is attached to the 1 st tape surface 3a of the element attaching portion 32. When the fastener element 4 is a spiral element, the fastener element 4 is sewn to the element attaching portion 32 by at least one thread.
In some cases, the slider body 6 has: a lower wing plate 61; a column part 62 for separating the right and left fastener elements 4 in an engaged state; an upper plate portion 63 coupled to an upper end of the column portion 62; a pair of claw portions 64 for holding the shaft portion of the tab 7; a pair of side wall portions 65 provided at left and right side edge portions of the lower blade 61; and a pair of flange portions 66 extending from the upper ends of the respective side wall portions 65 toward the upper plate portion 63. The 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 each other on the left and right sides of the column portion 62, and a single rear port is provided on the opposite side. A slit for passing the folded portion 33 of the fastener tape 3 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 and the element attaching portion 32 of the fastener tape 3.
The fastener elements 4 in the engaged state enter the slider body 6 through the rear opening of the slider body 6, and move in the space between the left and right side wall portions 65. When the fastener element 4 in the engaged state reaches the post portion 62, the engagement is released by the post portion 62. Each fastener element 4 in the non-engaged state moves out of the slider body 6 through each front opening. The fastener element 4 moves in a space vertically limited by the lower wing plate 61 and the flange 66. When the slider 5 moves, the flange portion 66 of the slider body 6 is always covered with the tape main portion 31 of the fastener tape 3. When the 1 st tape face 3a 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. Zipper 99 is therefore referred to as a "concealed zipper".
In some cases, the pull tab 7 has a shaft portion 71, a pair of bar 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 person's hand. By holding the shaft portion 71 of the tab 7 by the pair of claw portions 64 of the slider 5, the posture of the tab 7 can be maintained at any angle between the inverted posture and the inverted posture. For example, when the slider 5 is assembled, the shaft portion 71 of the tab 7 is disposed between the claw portions 64 before caulking, and then each claw portion 64 is caulked. The shaft portion 71 of the tab 7 is pressed between the pair of claw portions 64 and/or between the claw portions 64 and the placement portion 63a of the upper plate portion 63. By pressing the shaft portion 71 of the tab 7 in this manner, the posture of the tab 7 can be maintained over the entire pivoting range of the tab 7, and the tab 7 is not pivoted by gravity. The mounting portion 63a of the upper plate portion 63 is a portion on which the shaft portion 71 of the tab 7 is mounted. Additionally or alternatively, the claw portion 64 is sandwiched between the pair of rod portions 72, whereby the posture of the pull tab 7 can be maintained at any angle between the laid-down posture and the inverted posture. A mark such as ABC is provided on the grip portion 83. The indicia can be recessed or raised.
In some cases, the pull tab 7 is integrally formed to the slider body 6 based on insert molding. In this case, the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the laid-down 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 tab attaching portion of the slider body 6. In this case, the posture of the pull tab 7 can be maintained at any angle between the inverted posture and the laid-down posture. Specific forms of realizing that the posture of the pull-tab 7 can be maintained at any angle between the inverted posture and the laid-down posture are various and should not be limited to the illustrated examples.
Hereinafter, a method of manufacturing the slide fastener of the present disclosure is described with reference to fig. 4 to 9. Fig. 4 is a schematic view showing a system 400 for manufacturing the slide fastener 99. Fig. 5 is a schematic process diagram showing a step of attaching the pull tab 7 to the slider body 6 of the attachment box (japanese: セットボックス)115 supplied to the assembly machine 100 and turning the pull tab 7 to an inverted posture. Fig. 6 is a schematic process diagram showing a process of turning the pull tab 7 in an inverted posture while the slider 5 supplied from the parts feeder 200 passes through the chute (japanese: シュート) 602. Fig. 7 is a schematic diagram showing an alternative method of fig. 6. Fig. 8 is a schematic process diagram showing a process performed in the apparatus 300 for engaging the fastener element 4 with the slider body 6. Fig. 9 is a schematic process diagram showing a process performed in the apparatus 300 for engaging the fastener element 4 with the slider body 6.
In the system 400, a 1 st tab operation step of turning the tab 7 of the slider 5 toward an inverted posture is performed, and in the 1 st tab operation step, the tab 7 is provided on the slider body 6 so that the posture of the slider 5 can be maintained at an arbitrary angle between a fallen posture in which the tab 7 is fallen down with respect to the slider body 6 and an inverted posture in which the tab 7 is inverted with respect to the slider body 6, and a fastener element engagement step of engaging the fastener elements 4 included in the fastener stringer 2 with the slider body 6 of the slider 5 whose tab 7 is turned to the inverted posture side are performed. In some cases, the 1 st pull tab operation step is performed before the fastener element engaging step along the time axis, or the 1 st pull tab operation step is performed at a position further upstream than the fastener element engaging step, or the 1 st pull tab operation step is performed in an apparatus further upstream than the fastener element engaging step. The upstream is understood based on the manufacturing method of the slider 5 or the slide fastener 99. Engaging the fastener element 4 with the slider body 6 means inserting the fastener element 4 into an element passage between the rear opening and the front opening of the slider body 6.
In the 1 st pull-tab operation step, the pull-tab 7 is turned to an 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 the slider 5 held by the holder is alleviated, and/or smooth engagement of the fastener element 4 with the slider body 6 of the slider 5 is promoted. Additionally or alternatively, when the slider 5 is a slider for a concealed slide fastener, interference between the fastener tape 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 device 300 for engaging the fastener elements 4 with the slider body 6. The 1 st pull-tab operation is performed at a station assigned to the assembling machine 100 for attaching the pull-tab 7 to the slider body 6. Additionally or alternatively, the 1 st pull-tab operation process is performed while the slider 5 is moving along a 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, the operation is performed based on the action of the 1 st pushing member 501 provided in the assembling machine 100 or the 2 nd pushing member 502 provided along the chute 602.
Suppose that the 1 st tab operation is performed N times, where N is a natural number of 2 or more. For example, the 1 st pull-tab operation process is performed at a station assigned to the assembling machine 100, and in addition, is performed while the slider 5 is moved along the chute 602 connected to the parts feeder 200. In such a case, the probability of occurrence of a defective adjustment relating to the angle of the tab 7 can be reduced. It should be noted that the 1 st pull tab manipulation process can additionally or alternatively be performed in other devices.
The tab 7 is set at a target angle within an angle range of 30 to 150 degrees by the 1 st tab operation step. The angle of the pull tab 7 is an angle θ (see fig. 2) formed by the pull tab 7 and a plane orthogonal to the extending direction of the column portion 62 of the slider body 6. In the case where the tab 7 is bent between the base end portion 74 and the free end portion 75, the angle of the tab 7 is determined with reference to a portion of the tab 7 extending between the bent portion closest to the base end portion 74 and the base end portion 74. In the illustrated example, the pull tab 7 has a rod portion 72 extending between a bent portion of the pull tab 7 and a base end portion 74 of the pull tab 7. The angle of the pull tab 7 is represented by an 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 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 represented by an angle θ formed by the pull tab 7 and the upper plate portion 63 (or the upper surface thereof) of the slider body 6. When the flange portion 66 of 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 represented by an angle θ formed by the pull tab 7 and the flange portion 66 (or the upper surface thereof) of the slider body 6. A plane orthogonal to the extending direction of the post 62 of the slider body 6 is parallel to the moving direction (i.e., the front-rear direction) of the slider 5 for opening and closing the slide fastener. Thus, the angle of the tab 7 can also be understood as the angle between the front-rear direction and the extending direction of the tab 7.
In the case where the angle of the tab 7 is decreased when the tab 7 having an angle of 90 ° is rotated rearward (toward the 3 rd position P3), and the angle of the tab 7 is increased when the tab 7 having an angle of 90 ° is rotated forward (toward the 2 nd position P2), the tab 7 is set at a target angle within an angle range of 30 ° to 120 °. The pull tab 7 is promoted to fall backward in the 2 nd tab operation step. When the tab 7 bent at one point is folded backward, the grip portion 73 extending between the bent portion of the tab 7 and the free end portion 75 can be tilted backward and downward. This can reduce the volume when bundling a plurality of slide fasteners.
In some cases, the assembling 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 may 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, the slider body 6 being supplied to the mounting boxes 115; and a 1 st pushing member 501 positioned on the outer periphery of the turntable 110 for rotating the pull tab 7 toward the inverted posture. The slider body 6 is supplied to the mounting box 115 and positioned by a side pawl (japanese: サイドジョー) not shown. With the rotation of the turn table 110, the slider body 6 of the mounting box 115 provided to the turn table 110 is supplied to the respective stations S1 to S8, and the processing assigned to the respective stations S1 to S8 is performed.
For example, at the station S1, the slider body 6 is supplied to the mounting box 115 (see fig. 5 (a)). At the station S3, the pull tab 7 is supplied to the slider body 6 positioned at the mounting box 115. At station S4, the presence or absence and the front and back of the tab 7 are checked. At the station S5, the claw portion 64 of the slider body 6 is caulked by a pressing member, and the pull tab 7 is attached to the slider body 6 (see fig. 5 (b)). At station S6, the staking status is checked either mechanically or based on an image. At the station S7, the tab 7 is turned toward the inverted posture based on the movement of the 1 st pushing member 501 (see fig. 5 c).
In some cases, the 1 st pushing member 501 is straight toward the rotation center of the turntable 110, in other words, radially inward as understood based on the stations S1 to S12 arranged in the circumferential direction. The angle of the pull tab 7 can be set at a target angle according to the straight traveling distance of the 1 st pushing member 501. The 1 st pushing member 501 can be fixed to the rod tip of the cylinder. In some cases, the tab 7 collides with the stop member 601, and the deviation of the angle of the tab 7 is avoided or suppressed (see fig. 5 (c)). At the station S8, the slider 5 with the pull tab 7 attached to the slider body 6 is discharged. At the station S9, it is checked whether or not the side claws for fixing the slider body 6 at the fixed position with respect to the mounting box are broken. At the station S11, it is confirmed that the slider body 6 is not present in the mounting box.
The parts feeder 200 is a device for storing and feeding a set of sliders 5 assembled by the assembling machine 100. The parts feeder 200 has a guide plate that can be inserted into a slit of the slider body 6, and can convey the slider body 6 along the guide plate by imparting vibration to the guide plate. The slider 5 discharged from the parts feeder 200 is conveyed to the chute 602 and moved along the chute 602. In some cases, the slider 5 may move within the slide groove 602 due to gravity. The slide groove 602 is any cylinder that allows the slider 5 to slide, and may have a slit through which the pull tab 7 passes.
The 1 st pull-tab operation step can be performed in various forms while the slider 5 moves along the chute 602 connected to the parts feeder 200 for storing and feeding the slider 5. In some cases, a stopping member 603 for stopping the slider 5 moving along the chute 602 by gravity is provided, and the pull tab 7 of the slider 5 colliding with the stopping member 603 is turned toward the inverted posture based on the action of the 2 nd pushing member 502. The 2 nd pushing member 502 rotates by a predetermined angle in accordance with a rotational force supplied from a drive source such as a motor, and sets the angle of the pull tab 7 at a target angle. After the angle of the pull tab 7 is set to the target angle, the stop member 603 is operated to release the stop of the movement of the slider 5. In some cases, the 2 nd pushing member 502 rotates the tab 7 downward in the vertical direction, and thereby the slider 5 can be surely moved (dropped) along the chute 602 even before the 2 nd pushing member 502 returns to the home position. The slider 5 discharged from the slide groove 602 is held by the delivery holder 609. The lower blade 61 of the slider 5 is oriented in the horizontal direction orthogonal to the vertical direction by rotating the delivery holder 609 by 90 °. The combination of the chute 602 and the 2 nd urging member 502 can be understood as a unit.
The angle of the tab 7 set with the 1 st push member 501 can be the same as or different from the angle of the tab set with the 2 nd push member 502. In the case of fig. 6, the target angle of the tab 7 is 90 ° as in fig. 5. In the case of fig. 7, the target angle of the pull tab 7 differs from that of fig. 5 by less than 90 °. In consideration of the fact that there is a possibility that the angle of the tab 7 may be changed at the parts feeder 200 after being discharged from the assembling machine 100, in some cases, the tab 7 is relatively largely rotated by the 1 st pushing member 501, and then the tab 7 is relatively small rotated by the 2 nd pushing member 502.
As an option, the method of manufacturing a slide fastener further includes an inspection step of imaging the pull tab 7 rotated to the inverted posture side and inspecting a mark provided on the pull tab 7 based on the imaging data and the pre-registered information. In some cases, the mark 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, an imaging means 604 for imaging the pull tab 7 of the slider 5 moving along the chute 602 can be provided. The image pickup section 604 can be a camera such as a CMOS. The mark provided on the tab 7 is checked based on the imaging data acquired by the imaging means 604 and the pre-registration information. For the examination, a digital or analog operator, or a computer is used. The pre-registration information can be stored in a memory of the computer. The memory can be an internal memory of the CPU or an external memory. For example, the computer detects an edge line of a part of the flag from the image data, and determines whether or not the edge line is located within a position range in the image registered as the pre-registration information. Alternatively, the computer detects the contour of the marker from the captured image data, calculates the degree of coincidence with the contour registered as the pre-registered information, and compares the calculated degree of coincidence 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 inspecting the mark of the tab 7 at this position, the slider 5 with the tab having the error mark attached thereto can be effectively prevented from engaging with the fastener stringer 2.
As shown in fig. 8, the above-described fastener element engaging step may include a step of holding the slider 5 by the holder 605 and a step of engaging the fastener elements 4 included in the fastener stringer 2 with the slider body 6 of the slider 5 held by the holder 605. Various devices have been developed 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 conveying direction by a pair of left and right clamps (not shown) that clamp the pair of left and right fastener tapes 3 of the fastener stringer 2. The fastener elements 4 in the engaged state enter the slider body 6 through the rear opening of the slider body 6, and then the distance between the pair of left and right jigs is increased. Thereby, each fastener element 4 can smoothly move to the outside of the slider body 6 through the front opening of the slider body 6. After the target length of the fastener stringer 2 is pulled out by the jig, the fastener stringer 2 is cut.
As an option, the method of manufacturing the slide fastener further includes a 2 nd pull tab operation step of turning the pull tab 7 of the slider 5 engaged with the fastener element 4 toward the inverted posture in the 2 nd pull tab operation step. The 2 nd pull-tab operation step can be performed after the fastener element 4 is engaged with the slider 5 in the apparatus 300. As shown in fig. 9, the 2 nd pull-tab operation step can be performed based on the operation of the 3 rd pushing member 503 that moves straight toward the tape faces 3a, 3b of the fastener tape 3 included in the fastener stringer 2. The 3 rd pushing member 503 can be fixed to the rod tip of the cylinder.
The 3 rd pushing member 503 can have at least one guide surface 504, and the guide surface 504 rotates the pull-tab 7 whose posture is close to the inverted posture gradually close to the laid-down posture in accordance with the travel of the 3 rd pushing member 503. The guide surface 504 can be a surface inclined in the direction in which the fastener stringer 2 is conveyed. In some cases, the 3 rd pushing member 503 can include a set of guide surfaces 504a, 504b inclined in opposite directions to each other, i.e., in a V-shape. This makes it possible to more reliably collapse the tab 7 in either direction. It is also assumed that the 2 nd pull-tab handling step is performed by a human hand. The pull-tab 7 is put in a state of being fallen down by the second pull-tab operation step 2, and the volume when a plurality of slide fasteners are bundled can be reduced.
As shown in fig. 10, a mode in which the 2 nd pushing member 502 rotates the pull tab 7 toward the inverted posture is also conceivable. The 2 nd pushing member 502 moves linearly in accordance with power supplied from a drive source such as a motor, and rotates the pull tab 7 toward the inverted posture. When the pull tab 7 is rotated to the target angle, the 2 nd pushing member 502 is retreated. The 2 nd pushing member 502 is movable, for example, in a horizontal direction orthogonal to the vertical direction. Any guide member for guiding the movement of the 2 nd pushing member 502 can be used at the same time. After the angle of the pull tab 7 is set to the target angle, the stop member 603 is operated to release the stop of the movement of the slider 5. The 2 nd pushing member 502 rotates the tab 7 downward in the vertical direction, whereby the slider 5 can be surely moved (dropped) along the slide groove 602 even before the 2 nd pushing member 502 returns to the home position (i.e., retreats). The slider 5 discharged from the slide groove 602 is held by the delivery holder 609. The lower blade 61 of the slider 5 is oriented in the horizontal direction orthogonal to the vertical direction by rotating the delivery holder 609 by 90 °.
From the description, those skilled in the art can apply various modifications to the embodiments. Reference numerals have been included in the claims for ease of reference and are not intended to be used in a limiting sense.
