Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to such embodiments. Fig. 1 is an explanatory view schematically showing a synthetic resin slide fastener manufacturing apparatus (hereinafter, also simply referred to as "slide fastener manufacturing apparatus") 100 according to an embodiment of the present invention. Fig. 2 is a flowchart showing a processing step performed by the slide fastener manufacturing apparatus 100. Fig. 3 is a plan view showing the continuous fastener chain 10 in a broken state. Fig. 4 is a plan view of the fastener chain 10 in a state where the spacer 11 is formed. Fig. 5 is a plan view of the fastener chain 10 in a state where the reinforcing film 12 is adhered. Fig. 6 is a plan view of the fastener chain 10 in a state where the through hole portion 13 is formed.
The slide fastener manufacturing apparatus 100 is an apparatus for continuously mass-producing a finished slide fastener 30 shown in fig. 17 by performing various processes described below on a continuous slide fastener chain 10 obtained by injection-molding synthetic resin element rows 2, 2 on respective opposing edges of a pair of left and right long fastener tapes 1, 1 (see fig. 3). The fastener chain 10 may be said to include a pair of right and left fastener stringers 1a, 1a having element rows 2, 2 at opposite edges of the right and left fastener tapes 1, 1. Referring to fig. 1, a slide fastener manufacturing apparatus 100 includes: 1 st device 110; the 2 nd device 120; the 3 rd device 130; and a conveying mechanism 140 for conveying the fastener chain 10 to the 1 st apparatus 110, next to the 2 nd apparatus 120, and next to the 3 rd apparatus 130. Hereinafter, the side to which the fastener chain 10 is sent is referred to as "downstream", and the side opposite to the downstream in the conveying direction is referred to as "upstream". In the slide fastener manufacturing apparatus 100, a 1 st buffer 150a and a 2 nd buffer 150b, in which the slide fastener chain 10 is stopped during processing, are provided between the 1 st facility 110 and the 2 nd facility 120 and between the 2 nd facility 120 and the 3 rd facility 130, respectively. The conveying mechanism 140 includes a driving roller, a tension roller, a guide roller 141, various members constituting a conveying path, and the like, which guide the fastener chain 10 in the conveying path passing through the inside and outside of the 1 st apparatus 110, the 2 nd apparatus 120, and the 3 rd apparatus 130. The conveying mechanism 140 can temporarily stop the conveyance of the fastener chain 10, reverse the conveying direction and convey the fastener chain to the upstream side, or change the conveying speed. By providing the 1 st buffer 150a and the 2 nd buffer 150b, the transport mechanism 140 can be driven independently of the 1 st apparatus 110, the 2 nd apparatus 120, and the 3 rd apparatus 130, respectively.
1 st apparatus
The fastener chain 10 in which the element rows 2, 2 of the left and right fastener stringers 1a, 1a are in the engaged state (closed state) is supplied to the 1 st device 110 by the conveying mechanism 140, but the left and right fastener stringers 1a, 1a in which the element rows 2, 2 are in the non-engaged state (open state) may be in the engaged state (closed state) in the 1 st device 110. The 1 st device 110 includes: a gap generating means 111 for partially removing the element rows 2 at predetermined intervals in the longitudinal direction of the fastener chain 10 to form a gap portion 11 between the opposing edges of the fastener tape 1; a film bonding mechanism 112 for bonding a reinforcing film 12 to a rectangular region corresponding to approximately a half portion on the upstream side of the spacer 11 in the left and right fastener tapes 1, 1 of the fastener chain 10; and a punching mechanism 113 for forming a rectangular-shaped punching portion 13 on the downstream side in the reinforcing film 12. In the first apparatus 110, the fastener chain 10 is processed into the space portion 11, the reinforcing film 12, and the perforated portion 13 in an engaged state, so that the left and right fastener tapes 1, 1 are not displaced during conveyance.
The space generating means 111 partially removes the left and right element rows 2 in the closed state at predetermined intervals in the longitudinal direction of the fastener chain 10. Thereby, a space portion 11 is formed between the opposing edges of the left and right fastener tapes 1, 1. Referring to fig. 4, a relatively thick core portion 11a as a reinforcing portion remains at the facing edge portions of the fastener tapes 1 in the spacer portions 11. The presence or absence of the element row 2, the spacer portion 11, the perforated portion 13, and the like become the reference for positioning in the subsequent step, and are detected by a sensor and the like, not shown. The film bonding mechanism 112 bonds the reinforcing films 12 from both front and back sides of the fastener chain 10. The reinforcing film 12 functions as follows: the adhesion of the molten resin can be improved at the time of injection molding of the later-described openers (20, 21), and the operability can be improved by reinforcing both longitudinal end portions of the single slide fastener 30 as a final product. Referring to fig. 6, when forming the perforation portion 13, the perforation means 113 simultaneously perforates 2 through-holes 14, in total 4 through-holes, in each of the opposing edge portions of the left and right fastener tapes 1, 1 on the upstream side of the perforation portion 13 in the reinforcing film 12.
2 nd apparatus
The fastener chain 10, in which the partition portion 11, the reinforcing film 12, the perforated portion 13, and the like are processed by the 1 st apparatus 110, stays at the 1 st buffer portion 150a, and is supplied to the 2 nd apparatus 120 by the conveying mechanism 140. The 2 nd device 120 includes: a slider one-side threading mechanism 121 for threading the slider 3 from the perforated portion 13 one side through the element row of the fastener stringer 1a of one (left side in fig. 7) of the left and right fastener stringers 1a, 1a in an at least partially opened state; an upper stopper and opener injection molding mechanism 122 for simultaneously injection molding the socket body 20 with a socket bar and the insert bar 21, which are openers of the upstream-side fastener unit portion 10B through which the slider 3 is inserted on one side, and the 2 upper stoppers 22, which are 2 upper stoppers 22 of the downstream-side fastener unit portion 10A adjacent to the upstream-side fastener unit portion 10B on the downstream side via the through hole portion 13; and a chain closing mechanism 123 for closing the element rows 2, 2 of the left and right fastener stringers 1a, 1a in the at least partially opened state.
Fig. 7 is a plan view of the fastener chain 10 in an open state after the slider 3 is inserted in one side. Fig. 8 is a plan view of the fastener chain 10 in a state where the opener and the upper stopper 22 are injection-molded. Fig. 9 is a plan view showing the fastener chain 10 in a broken state from the opened state to the closed state. The left and right fastener stringers 1a, 1a in the closed state in the 1 st device 110 are partially opened at least on the upstream side and the downstream side near the perforated portion 13 to which the slider 3 is attached, in the upstream of the slider one-side inserting mechanism 121 of the 2 nd device 120. Further, the slider 3 may be inserted one-side by completely opening the left and right fastener stringers 1a, 1a upstream of the slider one-side insertion mechanism 121 of the device 2. In order to open the left and right fastener stringers 1a, 1a in the closed state, the fastener chain 10 is conveyed downstream in a state where a non-illustrated engagement releasing member such as a pin is inserted into the hole 13, and the element rows 2, 2 of the left and right fastener stringers 1a, 1a are separated one by one from the engagement releasing member as a starting point, and are opened. For example, the conveying paths of the left and right fastener stringers 1a, 1a may be branched in the vertical direction, and the element rows 2, 2 of the left and right fastener stringers 1a, 1a may be separated one by one from the branch point. Referring to fig. 7, in the present embodiment, the slider one-side threading mechanism 121 is configured to thread the left shoulder opening 3a of the slider 3 through the opposing edge portion where the reinforcing film 12 is adhered and the through hole 14 is formed from the through hole portion 13 of the left fastener stringer 1a, and thereafter, to feed the left and right fastener stringers 1a, 1a downstream with respect to the slider 3, thereby disposing the slider 3 on the left element row 2 (of the upstream fastener unit portion 10B).
Referring to fig. 8, the upper stop and opener injection molding mechanism 122 injection molds the socket body 20 with the socket bar on the left fastener stringer 1a of the upstream side fastener unit portion 10B of the slider 3 on one side, injection molds the insert bar 21 on the right fastener stringer 1a, and injection molds the upper stop 22 on the left and right fastener stringers 1a, 1a of the downstream side fastener unit portion 10A. The fastener unit sections (10A, 10B) are portions of the continuous fastener chain 10 that eventually become the single slide fastener 30, and the upper stop and opener injection molding mechanism 122 simultaneously molds the openers (20, 21) of one of the 2 fastener unit sections (10A, 10B) and the upper stop 22 of the other.
Fig. 10 is a plan view showing the lower mold 124 of the upper stopper and opener injection molding mechanism 122 on the back side (back side in fig. 10) of the fastener chain 10. Fig. 11 is a schematic sectional view taken along line a-a of fig. 10. The upper-stopper/opener injection molding mechanism 122 includes a lower mold 124, an upper mold not shown, and a runner 125 for supplying molten resin into cavities of the lower mold 124 and the upper mold. The cavity of the lower mold 124 and the upper mold is divided into 4 cavity parts corresponding to the plunger 21, the socket body 20 with the socket bar, and the 2 upper stoppers 22, 22. The runner 125 branches from a sprue 126 serving as a gate for the molten resin into 4 cavity portions. The socket body 20 with socket bar is formed at the opposite edge of the fastener stringer 1a on the left side of the upstream-side fastener stringer unit portion 10B, to which the reinforcing film 12 is bonded, on the upstream side (upper side in fig. 10) of the through-hole portion 13. The insert pin 21 is formed at an opposite edge portion corresponding to the socket body 20 with the socket bar in the fastener stringer 1a on the right side of the upstream-side fastener stringer unit portion 10B. The 2 upper stoppers 22 and 22 are formed adjacent to the upstream ends of the element rows 2 and 2 of the left and right fastener stringers 1a and 1a of the downstream-side fastener unit portion 10A. When the receptacle body 20 with the receptacle bar and the insert bar 21 are injection molded, the molten resin is also impregnated into the 4 through holes 14, and the resin solidified in the through holes 14 connects the receptacle body 20 with the insert bar 21 on the front and back sides of the fastener tape 1. This can improve the fixing force of the receptacle body 20 with the receptacle bar and the insert bar 21 to the fastener tape 1. After the injection-molded openers (20, 21) and the upper stopper 22 are solidified, the ejector pin 127 shown in fig. 11 retracted into the lower mold 124 is projected from the lower mold 124, whereby the openers (20, 21) and the upper stopper 22 can be separated from the runner 125 as shown in fig. 12. Next, as shown in fig. 13, the lower mold 124 (and the upper mold) moves in one of the left and right directions of the fastener chain 10 (the right side in fig. 13). This can suppress contact between the fastener chain 10 or the slider 3 and the runner 125 and the sprue 126 when the fastener chain 10 is conveyed downstream.
Fig. 14 is a plan view showing the fastener chain 10 in a state in which the chain closing mechanism 123 starts to form a closed state. Fig. 15 is a plan view of the fastener chain 10 in a state of being conveyed downstream from the state of fig. 14. The chain closing mechanism 123 includes: a pair of right and left rod-shaped engaging members 123a, and a driving unit (not shown) for moving each engaging member 123a in the right and left direction. The driving section allows the respective engaging elements 123a to move between an initial position at which they are separated from each other and a close position at which they are close to each other and the fastener chain 10 is sandwiched so that the left and right element rows 2, 2 are engaged with each other. Although not shown, each engaging member 123a is provided with a tape groove for receiving the fastener tape 1 when it is at the close position. After the slider 3 is once inserted into the fastener stringer 10, the left and right engaging elements 123a, 123a disposed on the upstream side of the position where the slider 3 is once inserted in the fastener stringer 10 in the conveying direction are moved from the initial position to the close position, and the left and right element rows 2, 2 are partially engaged with each other. By conveying the fastener chain 10 downstream while the left and right engaging elements 123a, 123a are once maintained at the close position, the left and right element rows 2, 2 of the corresponding upstream-side fastener unit portion 10B can be closed to the upper end or the vicinity of the upper end. Then, the left and right engaging members 123a, 123a return to the initial positions.
3 rd equipment
Fig. 16 is a plan view of the slide fastener chain 10 in a state where the socket body with socket bar 20 and the insert bar 21 are combined. Fig. 17 is a plan view showing the completed slide fastener 30, and shows a state in which the slider 3 is pulled down from the upper stopper 22. The 3 rd device 130 includes: a chain combining mechanism 131 for combining the socket body 20 with the socket bar and the plug bar 21; and a cutting mechanism 133 for cutting the fastener chain 10 in the width direction at a portion corresponding to the perforated portion 13. The chain combining mechanism 131 combines the socket body 20 with the socket bar and the plug bar 21 separated in the state of fig. 15. In fig. 16, the socket body 20 with the socket bar (not shown) and the insert bar 21 of the downstream-side fastener unit portion 10A are already combined, and after the combination, the downstream-side fastener unit portion 10A is conveyed to the downstream side, whereby the slider 3 of the downstream-side fastener unit portion 10A abuts against the upper stopper portion 22 and moves to the upper-stopper-portion regulation position where the further upward (upstream) movement thereof is regulated. The slider 3 can be moved relatively to a position before the upper stopper 22 shown in fig. 17, instead of abutting against the upper stopper 22. When the slider 3 is positioned at the upper stop portion restricting position as shown in fig. 16, most of the upper stop portion 22 is hidden in the slider 3. A slider pull-down mechanism for pulling down the slider 3 positioned at the upper stop regulation position may be additionally provided. The slider pull-down mechanism pulls down the slider 3 positioned at the upper stop portion restricting position to expose the upper stop portion 22. The exposed top dead center 22 can be automatically checked for proper formation by a checking mechanism using an image acquired by an imaging means such as a camera or a checking mechanism using a contact or non-contact sensor. Alternatively, whether or not the formation is normal can be checked by visual inspection of an operator. The visual inspection may be performed after the fastener chain 10 is cut into the slide fastener 30 by the cutting mechanism 133. The examination object of the examination function described above may include not only the upper portion 22 but also the openers (20, 21) or the lower portion. When the slider 3 having the combined openers (20, 21) is relatively moved to a position (see fig. 17) before the upper stopper 22, the inspection of the upper stopper 22 as described above can be performed in a subsequent step without adding a slider pull-down mechanism. Next, the fastener chain 10 is cut at a portion corresponding to the perforated portion 13 by the cutting mechanism 133, and a plurality of slide fasteners 30 are obtained. For convenience, the slider 3 in a state pulled down from the upper-stop regulation position by the slider pull-down mechanism is shown in fig. 17 showing the slide fastener 30 after cutting, but is cut by the cutting mechanism 133 after the slider 3 is pulled down. By being cut through the through-hole portion 13, a reinforcing film portion 12a as a part of the reinforcing film 12 remains at the upper end portion of the left and right fastener stringers 1a, 1a of the slide fastener 30, and a reinforcing film portion 12b as a part of the reinforcing film 12 remains at the lower end portion of the fastener stringers 1a, 1 a.
In the above embodiment 1, the example in which the chain combining mechanism 131 is provided in the 3 rd equipment 130 has been described, but the present invention is not limited to this. Fig. 18 is an explanatory view schematically showing a synthetic resin slide fastener manufacturing apparatus 100a according to embodiment 2 of the present invention. The slide fastener manufacturing apparatus 100a differs from the slide fastener manufacturing apparatus 100 of embodiment 1 in that the chain combining mechanism 131 is incorporated in the 2 nd device 120a instead of the 3 rd device 130 a. Therefore, in fig. 18, the same reference numerals are used for the chain combining mechanism 131, the mechanism common to the slide fastener manufacturing apparatus 100, and the like.
