Disclosure of Invention

Each of the processing portions such as the spacer portion processing portion and the end portion welding portion of the above-described slide fastener manufacturing apparatus has a dedicated structure according to the type of a slide fastener to be manufactured (product length, product thickness, product width, fastener element shape, tape thickness, tape width, top end shape, bottom end shape, opener shape, positioning part shape, and the like). Therefore, the slide fastener manufacturing apparatus is generally used as a dedicated manufacturing apparatus for manufacturing a single type of slide fastener.

However, the variety of products of slide fasteners has been greatly increased in recent years to cope with various designs and materials, and the demand for producing various products in a short period of time has been increasing. Therefore, in the production line, it is necessary to frequently replace the dedicated manufacturing apparatus for the existing product with another dedicated manufacturing apparatus for a new product type, and the complicated replacement work becomes a factor of reducing the production efficiency. In addition, in order to cope with the product type by adjusting the tooling change of each processing unit provided in the manufacturing apparatus, it is necessary to perform the adjustment one by one for each of a plurality of products, and the operator is required to be skilled, and the labor and time are also required. In addition, when other types are produced in small quantities, the individual dedicated production apparatuses have a low operating rate, and as a result, many dedicated production apparatuses having a low operating rate are installed in the production line, resulting in a reduction in space efficiency at the production site.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a slide fastener manufacturing apparatus capable of easily performing a setup change adjustment in a short time without requiring the operator to be skilled to manufacture different types of slide fasteners, and capable of performing the production with high productivity and space saving.

In the present invention, the main components and the mold in the processing section used for carrying out each step of the slide fastener manufacturing apparatus, which have different specifications depending on the type of slide fastener, are separated from the processing section main body to form a single block-shaped unit. The block-shaped unit is designed in consideration of a positioning method, a shape, a component configuration, a size, a weight, and an assembling method, which are different depending on the type of the slide fastener. Further, by providing the driving portion and the sensor portion only in the processing portion main body, the adjustment of each zipper type can be completed only by replacing the unit, and the machine change adjustment time can be shortened. According to this aspect, even an operator who does not have high expertise can easily and reliably perform the setup change in a short time at the slide fastener production site. The cell switching technique is also developed in the subsequent step, and a so-called production system capable of coping with various product specifications in one production line can be constructed.

This makes it possible to increase the operation rate and reduce the equipment cost, as compared with a dedicated manufacturing apparatus having a dedicated mechanism according to the type of slide fastener to be manufactured.

Further, since the replacement unit can easily cope with the manufacture of various slide fasteners, the labor and time required for the setup adjustment when manufacturing slide fasteners of different types can be significantly reduced.

In the present specification, with respect to the continuous fastener chain and the slide fastener, the starting end side (left side in fig. 1) of the conveying path is referred to as "upstream side" and the terminal end side (right side in fig. 1) of the conveying path is referred to as "downstream side" in the conveying direction of the continuous fastener chain by the slide fastener manufacturing apparatus. In the fastener manufacturing apparatus, the front side (the front side in the direction perpendicular to the paper surface of fig. 1) perpendicular to the conveying direction of the continuous fastener chain is referred to as "front side" or "front side", and the opposite side to the front side is referred to as "back side". In fig. 1, the vertical (vertical) direction is defined as the Z direction, the left-right direction orthogonal to the Z direction is defined as the X direction, and the vertical direction on the paper surface orthogonal to the X direction and the Z direction is defined as the Y direction.

The slide fastener manufacturing apparatus 1 of the present embodiment includes a preprocessing device 3 and a processing device 4 disposed downstream of the preprocessing device 3, and processes a continuous slide fastener chain while conveying the chain to manufacture a slide fastener.

The pretreatment device 3 is composed of a plurality of processing units, and includes a spacer processing unit 100, a reinforcing film welding processing unit 200, and an attachment processing unit 300 in this order from the upstream side. The spacer processed part 100, the reinforcing film welded processed part 200, and the mounting part processed part 300 in the illustrated example are supported by the support 7 erected on 1 frame 5, but are not limited thereto, and may be separately disposed on the installation surface.

Housing detection portions

9 and 11 are provided between the spacer processed portion 100 and the reinforcing film welded processed portion 200 and between the reinforcing film welded processed portion 200 and the mounting portion processed portion 300, respectively, and the

housing detection portions

9 and 11 house the continuous fastener chain 21 while slackening it, and detect whether the length of the continuous fastener chain 21 required for the next process is required.

The processing device 4 includes an element attaching device 13, a slider attaching and engaging device 15, and a chain accommodating portion 17, and is cut from a longitudinally long continuous fastener chain into a fastener chain as a product by a cutting portion not shown.

Fig. 2 (a) to (C) are views for explaining a manufacturing process of the slide fastener, and fig. 3 is a plan view of the cut slide fastener.

As shown in fig. 2 (a), the continuous fastener chain 21 processed by the aforementioned preprocessing device 3 includes a pair of longitudinal continuous fastener tapes 23 and a pair of continuous fastener element rows 25 provided along the opposing tape side edge portions of the pair of continuous fastener tapes 23. The fastener element row 25 is constituted by a plurality of fastener elements 27 formed by molding polyamide or polyester, for example. These fastener elements 27 are fixed to the tape side edge portion of the continuous fastener tape 23. In the illustrated example, a slide fastener including a fastener element formed by injection molding of a resin is exemplified, but the slide fastener is not limited to this, and may be another type of slide fastener such as a coil slide fastener.

The continuous fastener chain 21 is formed with a spacer portion 29 penetrating the front and back by removing the fastener elements 27 of a part of the continuous fastener element row 25 at predetermined intervals by the spacer portion processing portion 100. As shown in fig. 2 (B), the continuous fastener chain 21 having the spacers 29 is formed by welding the reinforcing film 31 to a part of the spacers 29 by the reinforcing film welding process portion 200. As shown in fig. 2 (C), the continuous fastener chain 21 is formed by processing an attachment portion 37 having a hole 33 as a through hole and a window 35 at the portion of the reinforcing film 31 to be welded by an attachment portion processing portion 300.

After the above-described processing, the upper stop portion 43 and the opener 44 are respectively injection-molded with resin at the end of the fastener element row 25 by the element attachment device 13 on the downstream side in the conveying direction, as shown in fig. 3. The socket 44a and the socket bar 44b of the opening piece 44 are integrally formed, and the tip (lower end in fig. 3) of the plug bar 44c is inserted into the socket 44 a. The resin forming the opener 44 is formed by passing through the hole 33 shown in fig. 2 (C) and connecting the front and back of the belt surface.

Then, the slider 41 is attached to the fastener element row 25 by the slider attaching and engaging device 15. Thereafter, the continuous fastener chain 21 is cut at the position of the window portion 35 (see fig. 2C) of the spacer portion 29, and is accommodated in the chain accommodating portion 17 as a fastener 45 having a predetermined length.

In this manner, the slide fastener manufacturing apparatus 1 configured as described above manufactures the slide fastener 45 by conveying the continuous fastener chain 21 and processing it by the preprocessing apparatus 3 and the processing apparatus 4.

Next, the spacer processing section 100, the reinforcing film welded processing section 200, and the mounting section processing section 300, which are a plurality of processing sections constituting the pretreatment device 3, will be described in detail in this order.

< spacer processing section >

First, the spacer processing section 100 will be explained.

Fig. 4 is a perspective view of the spacer processed part 100, and fig. 5 is an exploded perspective view of the spacer processed part 100. In addition, fig. 4 and 5 omit a detection roller to be discussed later.

The spacer processing section 100 includes a processing section main body 101, an upper unit (1 st upper unit) 103, and a lower unit (1 st lower unit) 105. The upper unit 103 and the lower unit 105 are prepared for each type of slide fastener to be manufactured, and can be attached to and detached from the processing portion main body 101.

The processing unit main body 101 includes: a column part 111 extending vertically; an upper unit mounting portion 113 extending to the Y-direction front side at the upper end of the pillar portion 111; and a lower unit mounting portion 115 extending to the Y-direction front side at the lower end of the pillar portion 111. In the processing unit main body 101, the upper unit 103 is attached from the front side to an upper unit attachment portion 113, and the lower unit 105 is attached from the front side to a lower unit attachment portion 115. A driving unit 117 (see fig. 4) for driving the upper unit 103 is provided above the processing unit main body 101. The driving unit 117 includes a driving member that moves up and down by a crank mechanism, for example, although not shown.

Fig. 6 is a view of the processing unit main body 101 shown in fig. 4, viewed in the direction of V1. The processing unit main body 101 is provided with a sensor portion 119, and the sensor portion 119 incorporates a detection roller as a length measuring roller for detecting the presence or absence of the continuous fastener chain 21 being conveyed, the conveying position thereof, and the like. The detection roller is rotated by the conveying operation of the conveyed continuous fastener chain, and the rotation of the detection roller is detected by an encoder. Here, the length measuring roller is not limited to the detection roller, and may be configured using another sensor element as long as the detection roller can detect the conveyance of the continuous fastener chain. In addition, various sensors (not shown) may be provided in the processing unit main body 101.

The sensor portion 119 may be provided in the lower unit 105 depending on the type of a fastener to be manufactured. At this time, the connector at the cable tip of the cable extending from the sensor portion 119 is connected to the connector provided on the processing portion main body 101 side. In this case, the shape of the connector may be changed according to the type of the size, the specification, or the like of the fastener to be manufactured, and the connector may be used as the recognition object for recognizing the lower unit 105. For example, in the various lower units 105, separate connectors are provided at the cable top ends, respectively. The processing unit main body 101 is provided with a connector to which only the lower unit 105 that can be handled by the spacer processing unit 100 of this configuration can be connected. With this configuration, the unit that can be used in the spacer processing unit 100 of the present configuration can be easily identified from the plurality of types of lower units 105 by the availability of the connection between the connectors, and erroneous mounting of the unit can be prevented.

Fig. 7 is a perspective view of the upper unit 103 of the spacer processing section 100, and fig. 8 is a cross-sectional view of the upper unit 103 shown in fig. 7 taken along line P1-P1.

The upper unit 103 includes a unit module 121 and a piston 123 provided substantially at the center of the unit module 121. The unit module 121 includes: a pair of bases 51 whose central portions are separated and the pair of bases 51 are arranged in parallel with each other; a pair of pins 53 connecting end portions of the pair of bases 51 to each other; a pair of claw members 55 having inclined guide surfaces 55a formed thereon, which are in rolling contact with the pins 53; a support member 57 for supporting the pair of claw members 55 so as to be slidable vertically; and a spring 59 that biases the claw member 55 upward.

The piston 123 incorporates a compression spring 125 (see fig. 8) that biases the piston 123 downward. A pin 127 as an element cutting member for cutting the fastener element is provided at the distal end of the piston 123, and the pin 127 can protrude from and retract to the lower surface side of the unit module 121.

When the push rod 61 is pressed down by the driving unit 117 shown in fig. 4, the claw member 55 of the unit module 121 abutting against the push rod 61 moves downward. Then, the inclined guide surface 55a of the claw member 55 shown in fig. 8 is pushed in toward the pin 53. Thereby, the pair of bases 51 move in a direction away from each other from the center portions facing each other. When the push rod 61 abuts on the piston 123 and presses down the upper end of the piston 123, the pin 127 protrudes downward from the lower surface of the base 51.

The upper unit 103 shown in fig. 7 is provided with a top plate 129 at an upper portion thereof. Here, the Y-direction width of the outer peripheral surface of the top plate 129 is Wa, and the thickness of the top plate 129 is ta.

Fig. 9 is a perspective view of the upper unit mounting portion 113 provided in the processing unit main body 101, as viewed obliquely from below.

The upper unit mounting portion 113 includes a detachable portion 131 that detachably supports the upper unit 103, and fixes the upper unit 103 to the processing portion main body 101. The detachable portion 131 has a support groove 133 formed in the pair of side walls 63. The top plate 129 of the upper unit 103 shown in fig. 5 is inserted into the support groove 133. That is, the support groove 133 is formed along the mounting direction (Y direction) in which the upper unit 103 is mounted on the processing unit main body 101.

The distance Wb between the groove bottoms (side walls in the groove) 135 of the support groove 133 shown in fig. 9 is slightly larger than the width Wa of the top plate 129 of the upper unit 103. The groove width tb of each support groove 133 is slightly larger than the thickness ta of the top plate 129 of the upper unit 103. The detachable portion 131 has a contact surface 139 on the back side of the processing portion main body 101, against which one end surface 129a (see fig. 7) of the top plate 129 of the upper unit 103 comes into contact.

As described above, the upper unit 103 is attached to the detachable portion 131 of the upper unit attachment portion 113 by inserting the side edges of the top plate 129 of the upper unit 103 from the front side of the processing portion main body 101 into the support grooves 133 and pressing the top plate 129 into contact with the contact surface 139. By engaging the top plate 129 with the support groove 133, the upper unit 103 is positioned in the conveying direction (X direction) of the continuous fastener chain 21 and the vertical direction (Z direction) orthogonal to the conveying direction. Further, the upper unit 103 is positioned in the unit attachment direction (Y direction) by the one end surface 129a of the top plate 129 being brought into contact with the contact surface 139.

In this way, the upper unit mounting portion 113 (machining portion side positioning portion) of the machining portion main body 101 supports the top plate 129 (unit side positioning portion) of the upper unit 103 by the groove bottom 135 of the support groove 133, the inner surface 137 of the support groove 133, and the abutment surface 139. Thus, the upper unit mounting portion 113 and the top plate 129 function as positioning portions that regulate the movement of the upper unit 103 and position each other.

Fig. 10 is an explanatory view showing a state in which the upper unit 103 is attached to the upper unit attachment portion 113, and is a bottom view of the upper unit attachment portion 113 as viewed from below. At least a pair of fixing holes 141 are formed in the top plate 129 shown as a hatched portion in the drawing of the upper unit 103. In the top plate 129 of the illustrated example, the fixing holes 141 are formed in a total of 4 positions at diagonal positions of the top plate 129. In the detachable portion 131 of the upper unit mounting portion 113, screw holes, not shown, are formed at positions corresponding to the fixing holes 141. The fixing bolt 143 is inserted into the screw hole through the fixing hole 141, and the top plate 129 of the upper unit 103 is fixed to the upper unit mounting portion 113. Further, the following configuration may be adopted: instead of the fixing bolt 143, a positioning pin (not shown) is provided so as to be freely movable downward from the detachable portion 131 of the upper unit mounting portion 113, and the positioning pin is inserted into the fixing hole 141 of the top plate 129 to position both of them.

Fig. 11 is a perspective view of the lower unit 105.

The lower unit 105 includes a unit module 151 and a pair of gripping portions 153 arranged at an upper portion of the unit module 151 with an interval therebetween in the conveying direction. The pair of gripping portions 153 has a pair of gripping pieces 155 on a lower surface facing the conveying path of the continuous fastener chain 21. The pair of grip pieces 155 is supported by the grip 153 so as to be movable in a direction orthogonal to the conveying direction. Each gripping piece 155 is pressed against the upper surface of the continuous fastener chain 21, and fixes the continuous fastener chain 21 to the lower unit 105.

A bottom plate 157 is mounted to a lower portion of the lower unit 105. The bottom plate 157 has engaging portions 161 protruding outward in the conveying direction at both ends in the conveying direction of the continuous fastener chain 21. Each engaging portion 161 has an engaging recess 163 opened on the side opposite to the lower unit mounting portion 115 shown in fig. 5. Further, a positioning step portion 165 recessed toward the front side in the mounting direction is formed on the bottom plate 157 at the mounting direction tip end side (the front side in fig. 11) of the lower unit mounting portion 115.

Fig. 12 is a perspective view of the lower unit mounting portion 115.

The lower unit mounting portion 115 includes a base portion 171 and a contact portion 172 disposed on the rear side of the base portion 171. The upper surface of the base portion 171 serves as a support surface 173 for supporting the bottom plate 157 of the lower unit 105. The contact portion 172 has a pair of contact surfaces 175 and 176 protruding from the back side to the front side at both ends in the X direction.

A positioning portion 177 formed of an L-shaped protrusion is formed on one of the abutment surfaces 175. In the positioning portion 177, a lower surface facing the base portion 171 is a vertical positioning surface 181, and a surface facing the center side of the lower unit mounting portion 115 is a horizontal positioning surface 183. A projection 185 having a flat surface at its tip is formed on the other contact surface 176. The lower surface of the protruding portion 185 facing the base portion 171 is a vertical positioning surface 187, and the surface facing the center side of the lower unit mounting portion 115 is a horizontal positioning surface 183.

A pair of pins 189 is provided upright on the base 171 on both sides in the conveyance direction (X direction) and on the front side of the processing unit main body 101. As shown in fig. 5, a fixing member 191 that is pressed against the rear side of the lower unit 105 in the insertion direction is fixed to the front side of the base 171 by a fixing bolt 193. A long hole extending in the vertical direction is formed in the fixing member 191, and a fixing bolt 193 is inserted into the long hole. The fixing bolt 193 is fastened through the long hole, so that the fixing member 191 can adjust the fixing position up and down.

Fig. 13 (a) and (B) are views showing a state in which the lower unit 105 is attached to the lower unit attachment portion 115, wherein (a) is a plan view of the lower unit attachment portion 115, and (B) is a side view of the lower unit attachment portion 115.

The lower unit 105 shown as a shaded portion in fig. 13 (a) is inserted from the front side of the processing unit main body 101 along the support surface 173 of the base 171. The lower unit 105 is press-fitted to the lower unit mounting portion 115 until the distal end surface of the bottom plate 157 abuts against the abutment surfaces 175 and 176 while abutting against the support surface 173.

Fig. 14 is a view in the direction of V2 of the lower unit shown in fig. 11.

When the lower unit 105 is mounted to the lower unit mounting portion 115 (see fig. 12), the upper and lower positioning surfaces 181 of the positioning portion 177 abut against the upper surface of the positioning step portion 165 of the bottom plate 157 of the lower unit 105. The horizontal positioning surface 183 of the positioning portion 177 abuts against the side surface of the unit module 151 of the lower unit 105. As shown in fig. 13 (B), the upper and lower positioning surfaces 187 of the projecting portion 185 of the abutting portion 172 abut against the upper surface of the bottom plate 157 of the lower unit 105. Thereby, the lower unit 105 performs positioning in the conveying direction (X direction) of the continuous fastener chain 21, the vertical direction (Z direction) orthogonal to the conveying direction, and the unit attachment direction (Y direction) orthogonal to the conveying direction and the vertical direction.

In this way, in the lower unit mounting portion 115 (the processing portion side positioning portion) of the processing portion main body 101, the bottom plate 157 (the unit side positioning portion) of the lower unit 105 is supported by the supporting surface 173, the abutting

surfaces

175 and 176 of the base 171, the upper and lower positioning surfaces 181 of the positioning portion 177, the horizontal positioning surface 183 of the positioning portion 177, the upper and lower positioning surfaces 187 and the horizontal positioning surface 183 of the protruding portion 185, respectively. Thus, the lower unit mounting portion 115 and the bottom plate 157 function as positioning portions that regulate the movement of the lower unit 105 and position them with respect to each other.

When the lower unit 105 is press-fitted into the lower unit mounting portion 115 from the front of the processing unit main body 101, the pin 189 erected on the base portion 171 engages with the engagement recess 163 in the engagement portion 161 of the bottom plate 157. Thus, the lower unit 105 is supported by the lower unit mounting portion 115 without rattling on the front side of the processing unit main body 101.

As shown in fig. 4, the engagement portion 161 of the lower unit 105 is fixed to the base portion 171 by fastening with a pin 189. Thus, the bottom plate 157 of the lower unit 105 is reliably locked to the fixing member 191, and the mounted state is stably maintained even when an external force is applied. The fixing member 191 is fixed to the base 171 by a fixing bolt 193 in a state of abutting against the lower unit 105, and the fixing of the lower unit 105 is reinforced.

According to the spacer processing section 100 described above, when the continuous fastener chain 21 is fed to the conveying path between the upper unit 103 and the lower unit 105 shown in fig. 4, the continuous fastener chain 21 is gripped by the gripping section 153 of the lower unit 105 shown in fig. 11. When the driving unit 117 of the processing unit main body 101 is driven in this state, the piston 123 of the upper unit 103 shown in fig. 8 is pushed down by the push rod 61. The pin 127 at the tip of the piston 123 projects downward. Then, a part of the fastener elements 27 of the fastener element row 25 of the continuous fastener chain 21 is cut and removed by the pin 127. Thereby, as shown in fig. 2 (a), the continuous fastener chain 21 is formed with the spacer portion 29.

The continuous fastener chain 21 is fed by a conveying drive unit, not shown, and conveyed on a conveying path. The amount of movement of the continuous fastener chain 21 is measured by the detection roller of the sensor portion 119. The conveyance of the continuous fastener chain 21 is controlled based on the measurement result of the movement amount, and the spacer 29 is formed at the desired fastener element cutting position in the continuous fastener chain 21 by the above-described operation.

In the spacer processing section 100 of this configuration, when performing a setup change for switching the type of slide fastener to be manufactured, the upper unit 103 and the lower unit 105 attached to the processing section main body 101 are replaced with the upper unit 103 and the lower unit 105 corresponding to the slide fastener to be manufactured next.

When the upper unit 103 is detached from the processing unit main body 101, the fixing bolt 143 in the detachable portion 131 of the upper unit attachment portion 113 shown in fig. 10 is loosened. Then, the upper unit 103 is pulled out to the front side so that the top plate 129 is pulled out from the support groove 133. Thereby, the upper unit 103 is easily detached from the processing unit main body 101.

When the lower unit 105 is detached from the processing unit main body 101, first, the fixing member 191 is moved downward by loosening the fixing bolt 193 shown in fig. 4. Then, the pair of pins 189 is loosened and the lower unit 105 is pulled out to the front side. Thereby, the lower unit 105 is easily detached from the processing portion main body 101.

When the upper unit 103 and the lower unit 105 corresponding to the subsequent manufacturing are assembled to the processing unit main body 101, the positioning in the conveying direction (X direction), the vertical direction (Z direction), and the unit attachment direction (Y direction) orthogonal to the conveying direction and the vertical direction of the continuous fastener chain 21 can be accurately performed with a simple operation as described above. Therefore, the setup time can be significantly reduced. The machining unit main body 101 has an insertion shape for receiving the upper unit 103 and the lower unit 105, and thus each unit is accurately set at a predetermined position when the units are assembled. In this way, since the setup change is performed without the need for operator's skill, it is possible to quickly cope with the production of various products and to construct a production line having improved production efficiency at low cost.

Next, a sensor unit provided in the processing unit main body 101 will be described.

Fig. 15 is an explanatory diagram for explaining a movement amount detection operation by the sensor unit 119 provided in the processing unit main body 101.

A conveying path of the continuous fastener chain 21 is provided in the lower unit mounting portion 115. The sensor 119 is provided so that the built-in detection roller is disposed facing the conveyance path.

The detection roller is a roller that rotates together with the encoder, and the roller surface is brought into contact with the conveyed continuous fastener chain 21 and rotates as the continuous fastener chain 21 moves. The rotation of the roller is detected by an encoder, and the amount of movement of the continuous fastener chain 21 is measured.

The sensor 119 is formed separately from the upper unit 103 and the lower unit 105, and is fixed to the machining unit main body 101. Therefore, even if the upper unit 103 and the lower unit 105 of various types are supported by the processing unit main body 101 at the time of machine setup, the sensor portion 119 is always accurately positioned with respect to the conveying path of the continuous fastener chain 21.

On the other hand, the lower unit 105 is positioned with high accuracy on the processing portion main body 101 by the positioning portion described above. Further, since the conveyance path of the continuous fastener chain 21 provided in the lower unit 105 is provided at a predetermined position with reference to the positioning portion of the lower unit 105, when the lower unit 105 is positioned in the processing portion main body 101, the positions of the detection roller of the sensor portion 119 and the conveyance path of the lower unit 105 are uniquely determined. Since the upper unit 103 is similarly positioned in the processing unit main body 101, the positions of the detection roller of the sensor 119 and the upper unit 103 are also uniquely determined.

In addition, other sensors may be provided in the processing unit main body 101 in addition to the detection roller. Since the sensor portion 119 and other sensors are fixed to the processing portion main body 101, the continuous fastener chain 21 is measured by the same sensor portion at all times in the conveyance paths of the plurality of types of lower units 105 even during setup change, and therefore, the reproducibility of measurement is improved, and stable and high-precision manufacturing can be realized.

In this way, by positioning each part of the continuous fastener chain as the object to be processed on the processing unit main body side and providing the unit side with a positioning structure that matches the reference coordinate system of the unit itself with the reference coordinate system of the processing unit main body, the replacement of the unit, i.e., the tooling change operation, can be made extremely efficient while maintaining high positional accuracy. As a result, the time required for the setup change can be shortened, and a production line capable of quickly coping with various types of slide fasteners can be constructed.

The above-described operational effects are similarly obtained in the following steps.

< reinforced film welding processing section >

Next, the reinforcing film fusion-processed part 200 will be described.

Fig. 16 is a perspective view of the reinforcing-film-welded part 200, and fig. 17 is an exploded perspective view of the reinforcing-film-welded part.

The reinforcing film fusion processing part 200 includes a processing part main body 201, an upper unit (2 nd upper unit) 203, and a lower unit (2 nd lower unit) 205. The upper unit 203 and the lower unit 205 are prepared for each type of slide fastener 45 to be manufactured, and can be easily attached to and detached from the processing portion main body 201. The reinforcing film fusing and processing unit 200 includes a feeding mechanism 207, and the feeding mechanism 207 feeds the continuous fastener chain 21 from the aforementioned spacer processing unit 100.

The processing unit main body 201 includes a substrate 211 and a column portion 213 erected on the substrate 211. An upper unit mounting portion 215 supported to be movable up and down is provided on the upper front side of the column portion 213, and a lower unit mounting portion 217 is provided on the lower front side. The upper unit 203 is attached to the upper unit attachment portion 215 from the front side of the processing portion main body 201. The lower unit 205 is attached to the lower unit attachment portion 217 from the front side of the processing portion main body 201. A vertical movement driving unit 219 for driving the upper unit mounting unit 215 to move up and down is provided on the upper portion of the processing unit main body 201. As the vertical movement driving unit 219, for example, a vertical movement cylinder is used.

The release mechanism 207 is fixed between the upper unit mounting portion 215 and the lower unit mounting portion 217 of the column portion 213, and conveys the continuous fastener chain 21 between the upper unit 203 and the lower unit 205.

The feeding mechanism 207 detects the presence and position of the continuous fastener chain 21 being conveyed, and includes various sensor units, which will be described in detail later.

Fig. 18 is a perspective view of the upper unit 203.

The upper unit 203 includes a unit module 231 and an ultrasonic horn 235, and the unit module 231 houses: an oscillator 233 that converts an input drive signal into an electric signal of a high frequency (for example, 20kHz to 35 kHz); a transducer (not shown) connected to the oscillator for converting an electric signal into mechanical vibration energy; and a booster (boost) 234 for amplifying the vibration of the transducer, the ultrasonic horn 235 being connected to the booster 234.

A pair of positioning plates 237 is fixed to both end surfaces of the upper unit 203 in the X direction of the unit module 231. The unit block 231 integrated with the positioning plate 237 is driven by the vertical movement driving unit 219 together with the upper unit mounting portion 215, and the ultrasonic horn 235 is moved up and down.

A pair of positioning abutting portions 239 projecting toward the distal end side in the unit attachment direction (Y direction) with respect to the processing unit main body 201 are formed on the pair of positioning plates 237, respectively. Insertion holes 241 penetrating in the unit mounting direction (Y direction) are opened in the distal end surfaces of the positioning contact portions 239. The insertion holes 241 are long holes having a large diameter in the vertical direction (Z direction). The fixing bolt 243 is inserted into the insertion hole 241 from the front side. The fixing bolt 243 is screwed into the screw hole 253 of the processing unit main body 201 to fix the upper unit 203 to the processing unit main body 201.

An L-shaped positioning piece 245 is fixed to one end of the unit module 231 in the X direction. As shown in fig. 16 and 17, a bolt 246 penetrating in the vertical direction (Z direction) is attached to the positioning piece 245, and the height position of the lower end of the bolt 246 can be adjusted.

Fig. 19 is a perspective view of the processing unit main body 201 of the reinforcing film fusion processing unit 200. In fig. 19, the discharge mechanism 207 is omitted.

The processing portion main body 201 includes a pair of

side support portions

225A and 225B arranged along the vertical direction (Z direction). The upper unit 203 shown in fig. 17 is supported so that the side surfaces thereof can be raised and lowered by abutting against the pair of

side support portions

225A and 225B.

The upper unit mounting portion 215 has a pair of

abutment surfaces

251A, 251B against which the positioning abutment portion 239 of the positioning plate 237 shown in fig. 18 abuts. The pair of

contact surfaces

251A and 251B extend in the Z direction, and have a plurality of screw holes 253 that are screwed to fixing bolts 243 inserted into insertion holes 241 of the positioning plate 237. On one contact surface 251A,

positioning walls

255A, 255B are formed along the Z direction on both sides in the X direction. On the other abutment surface 251B, a positioning wall 255C is formed along the Z direction only on one side in the X direction. Positioning pins 257 are provided to protrude from the lower end portions of the pair of

contact surfaces

251A and 251B, respectively.

On the upper unit mounting portion 215, a positioning piece 259 is integrally provided so as to protrude forward in the Y direction (toward the front side in fig. 19) on the X direction outer side of the positioning wall 255A on the mounting side of the upper unit 203. The upper surface 259a of the positioning piece 259 serves as a contact surface that contacts the bolt 246 of the positioning piece 245 provided in the upper unit 203.

Fig. 20 (a) is a horizontal partial sectional view schematically showing a state in which the upper unit 203 is attached to the upper unit attachment portion 215, and (B) is a horizontal partial sectional view schematically showing a state in which the lower unit 205 is attached to the lower unit attachment portion 217.

In order to mount the upper unit 203 to the upper unit mounting portion 215, as shown in fig. 20 (a), the positioning contact portion 239 of the positioning plate 237 of the upper unit 203 is brought into contact with the pair of

contact surfaces

251A and 251B of the upper unit mounting portion 215 from the front side of the processing portion main body 201. Then, the upper unit 203 is positioned in a unit attachment direction (Y direction) orthogonal to the conveying direction (X direction) of the continuous fastener chain 21.

As shown in fig. 17, the upper unit 203 is fixed to the upper unit mounting portion 215 by inserting the fixing bolt 243 into the insertion hole 241 and screwing it into the screw hole 253. At this time, the lower end of the bolt 246 provided in the positioning piece 245 of the upper unit 203 is brought into contact with the positioning piece 259 of the upper unit mounting portion 215, and the height position of the upper unit 203 mounted on the upper unit mounting portion 215 is adjusted. That is, the mounting height of the upper unit 203 is finely adjusted by increasing or decreasing the amount of projection of the adjusting bolt 246.

When the positioning abutting portion 239 of the positioning plate 237 abuts against the abutting

surfaces

251A and 251B of the upper unit mounting portion 215, the

positioning walls

255A, 255B, and 255C shown in fig. 20 (a) abut against the side surfaces of the positioning plate 237. Thereby, the upper unit 203 is positioned in the conveying direction (X direction) of the continuous fastener chain 21.

The lower end of the positioning plate 237 of the upper unit 203 abuts on the positioning pin 257 on the upper unit mounting portion 215 side shown in fig. 19. Thus, the upper unit 203 is positioned in the up-down direction (Z direction) with respect to the upper unit mounting portion 215.

In this way, the upper unit mounting portion 215 (processing portion side positioning portion) of the processing portion main body 201 positions and supports the positioning plate 237 (unit side positioning portion) by the side surfaces of the pair of

abutment surfaces

251A, 251B, the

positioning walls

255A, 255B, and 255C, and the positioning pins 257.

The upper unit mounting portion 215 is driven to move up and down by an up-and-down driving portion 219. The lowering operation of the upper unit mounting portion 215 is restricted by the lower end portion 229 of the upper unit mounting portion 215 shown in fig. 16 coming into contact with the contact piece 227 (see fig. 19) fixed to the column portion 213. The height position of the upper unit 203 relative to the column portion 213 is finely adjusted by the aforementioned bolt 246 and positioning piece 259 of the positioning piece 245.

According to the above configuration, the upper unit attachment portion 215, the positioning plate 237, the positioning piece 259, and the bolt 246 function as the positioning portion of the upper unit 203.

Fig. 21 is a perspective view of the lower unit 205 of the reinforcing film fusion-processing part 200.

The lower unit 205 has a unit block 261 and an anvil 263 provided at an upper portion of the unit block 261. The surface of the unit module 261 on the side of attachment to the processing portion main body 201 serves as a positioning abutment surface 265. A positioning projection 267 projecting toward the distal end side in the mounting direction with respect to the processing unit main body 201 is formed along the vertical direction (Z direction) on the positioning abutment surface 265. In the unit module 261, a plurality of insertion holes 269 that penetrate through the positioning projection 267 in the front-rear direction (Y direction) are formed on both sides in the X direction. Fixing bolts 271 are inserted into these insertion holes 269 from the front side.

As shown in fig. 19, the lower unit mounting portion 217 of the processing portion main body 201 has an abutment surface 281 that abuts against the unit block 261 of the lower unit 205. The contact surface 281 is formed with a positioning groove 283 into which the positioning projection 267 of the lower unit 205 can be fitted. The abutment surface 281 is formed with screw holes 285 on both sides of the positioning groove 283 in the X direction, to which fixing bolts 271 inserted into the insertion holes 269 are screwed.

In order to attach the lower unit 205 to the lower unit attachment portion 217, as shown in fig. 20 (B), the positioning projection 267 of the lower unit 205 is fitted into the positioning groove 283 of the lower unit attachment portion 217. Then, the positioning contact surface 265 of the lower unit 205 is brought into contact with the contact surface 281 of the lower unit mounting portion 217 from the front side of the processing portion main body 201. Thereby, the abutment surface 281 of the lower unit mounting portion 217 abuts against the positioning abutment surface 265 of the lower unit 205, and the lower unit 205 is positioned in the unit mounting direction (Y direction).

The positioning projection 267 of the lower unit 205 is fitted into the positioning groove 283 of the lower unit mounting portion 217, and the side surface of the positioning projection 267 abuts against the inner wall surface of the positioning groove 283. Thereby, the lower unit 205 is positioned in the conveying direction (X direction). Then, the lower unit 205 is placed on the opening 221 of the substrate 211 shown in fig. 17, whereby the lower unit 205 is positioned in the vertical direction (Z direction).

Therefore, the contact surface 281 of the lower unit mounting portion 217 (processing portion side positioning portion) of the processing portion main body 201, the inner surface of the positioning groove 283, and the upper surface of the substrate 211 are supported by the surfaces (unit side positioning portion) of the positioning convex portion 267 of the lower unit 205 and the like. In this way, the surfaces of the lower unit mounting portion 217, the positioning projecting portion 267, and the like function as positioning portions that regulate and position the movement of the lower unit 205.

When the lower unit 205 is disposed on the lower unit mounting portion 217, the screw hole 285 of the contact surface 281 is disposed in the insertion hole 269 of the unit module 261. When the fixing bolt 271 is inserted into the insertion hole 269, a radial gap is formed between the inner circumferential surface and the bolt 271, and the lower unit 205 has a slight position adjustment margin. The lower unit 205 is fixed to the processing unit main body 201 in a state of being positioned in the processing unit main body 201 by screwing the fixing bolt 271 into the screw hole 285.

In the reinforcing film welding process part 200, the continuous fastener chain 21 is fed to the feeding mechanism part 207 disposed between the upper unit 203 and the lower unit 205 shown in fig. 16. The reinforcing film 31 shown in fig. 2 (B) is supplied to the feeding mechanism 207 from an appropriate reinforcing film supply mechanism (not shown). The reinforcing film supply mechanism arranges a reinforcing film 31 on the spacer 29 of the continuous fastener chain 21 being conveyed.

In this state, when the unit block 231 is lowered by the vertical movement driving unit 219 of the processing unit main body 201 shown in fig. 16, the ultrasonic horn 235 abuts against the reinforcing film 31 which is supplied from a reinforcing film supply mechanism not shown and is disposed on the partition 29, as shown in fig. 22. Thus, the spacer 29 of the continuous fastener chain 21 is sandwiched between the ultrasonic horn 235 of the upper unit 203 and the anvil 263 of the lower unit 205 via the reinforcing film 31. When the ultrasonic horn 235 is ultrasonically vibrated by the ultrasonic generator in this state, the reinforcing film 31 is welded to the spacer 29 of the continuous fastener chain 21 by frictional heat generated by the ultrasonic vibration.

In the reinforcing film fusion processing part 200, at the time of machine adjustment in manufacturing a different type of slide fastener 45, the upper unit 203 and the lower unit 205 attached to the processing part main body 201 shown in fig. 16 are changed to a combination of the ultrasonic horn 235 and the anvil 263 corresponding to the slide fastener 45 to be manufactured next.

When the upper unit 203 is detached from the processing unit main body 201, the fixing bolt 243 for fastening the upper unit 203 to the upper unit mounting portion 215 of the processing unit main body 201 is loosened to release the fastening. Thereby, the upper unit 203 is easily detached from the processing portion main body 201. When the lower unit 205 is detached from the processing unit main body 201, the fixing bolt 271 for fastening the lower unit 205 to the lower unit mounting portion 217 of the processing unit main body 201 is loosened and the fastening is released. Thereby, the lower unit 205 is easily detached from the processing unit main body 101.

In addition, when the upper unit 203 and the lower unit 205 corresponding to the subsequent manufacturing are assembled to the processing unit main body 201, the positioning in the conveying direction (X direction), the vertical direction (Z direction), and the unit mounting direction (Y direction) can be accurately performed by the simple work as described above. Therefore, the setup time can be significantly reduced. Further, since the setup change is performed without requiring the operator's skill, the setup change can be quickly applied to the production of various product types, and a production line with improved production efficiency can be constructed at low cost.

The upper unit 203 and the lower unit 205 are fixed to the machining unit main body 201 by fixing

bolts

243 and 271 from the front direction of the machining unit main body 201. In this way, the unit can be fixed from the front direction or the direction directly above the processing unit main body, and the work efficiency and time for unit replacement can be reduced.

Next, a sensor unit provided in the processing unit main body 201 will be described.

Fig. 23 is a perspective view showing the structure of the ejection mechanism 207 of the processing unit main body 201.

The discharge mechanism 207 is provided with a spacer portion detecting portion 287 above the conveying path of the continuous fastener chain 21, and a distance detecting portion 288 for detecting the distance to the end of the spacer portion below the conveying path. The spacer section detecting section 287 and the distance detecting section 288 function as sensor sections that detect the conveying position of the continuous fastener chain 21.

The conveyance path of the continuous fastener chain 21 is formed between a lower rail 289 that supports the lower side of the continuous fastener chain 21 and an upper rail 290 that is disposed above the lower rail 289 with the continuous fastener chain 21 interposed therebetween.

The spacer portion detecting portion 287 includes the rail support portion 73, the rocking lever 75, the rotating disk 77, the detecting piece 79, and the optical sensor 81 as a position detecting sensor. The rail support portion 73 is provided upright from the lower rail 289, and supports the upper rail 290 to be movable up and down by the elastic force of the spring 71. The swing lever 75 is supported on the upper rail 290 so as to be swingable about a fulcrum 75a, and is biased in one direction (clockwise direction in fig. 23) by the compression spring 74. The rotating disc 77 is supported by one end of the swing lever 75, and has a plate thickness smaller than a width perpendicular to the conveying direction of the spacer 29 (see fig. 2 a) of the continuous fastener chain 21. A detection piece 79 made of an L-shaped plate material is provided at the other end of the swing lever 75. The optical sensor 81 is fixed to a fixed side, not shown, with a part of the detection piece 79 interposed therebetween, and detects the presence or absence of movement of the detection piece 79.

The distance detecting unit 288 includes the fixed plate 85, the slide rail 87, the slide member 89, the detecting piece 90, the optical sensor 91 as a position detecting sensor, and the chain locking member 93. The fixing plate 85 is fixed to the processing unit main body 201 (see fig. 17), and the slide rail 87 is fixed to the fixing plate 85. The slide member 89 is movably supported by the slide rail 87, and is biased by a spring 88 in a leftward direction in the drawing along the slide rail 87. A detection piece 90 made of a plate material is fixed below the sliding member 89, and a chain locking member 93 is fixed above the sliding member 89. As shown in fig. 24, the chain locking member 93 has a locking portion 93a protruding upward at the distal end. The optical sensor 91 is fixed to a member such as the fixed plate 85 on the processing unit main body 201 side with the distal end portion of the detection piece 90 extending from the slide member 89 interposed therebetween.

Fig. 25 (a) and (B) are explanatory diagrams showing operations of the spacer section 287 and the distance detection section 288 in stages.

As shown in fig. 25 (a), when the continuous fastener chain 21 is conveyed to the conveyance path between the lower rail 289 and the upper rail 290, the rotary disk 77 rotates while contacting the continuous fastener chain 21. When the spacer 29 of the continuous fastener chain 21 reaches a position directly below the rotary disk 77, the rotary disk 77 is fitted into the opening of the spacer 29. Then, the swing lever 75 swings as indicated by an arrow Pa in the drawing, and the detection piece 79 is separated from the light detection region of the photosensor 81. The optical sensor 81 outputs a detection signal to a control unit, not shown. The control unit detects the timing at which the detection piece 79 is separated from the light detection region as the timing at which the spacer 29 of the continuous fastener chain 21 arrives, based on the input detection signal.

When the continuous fastener chain 21 is further conveyed, the downstream end in the conveying direction of the spacer 29 is locked by the locking portion 93a of the chain locking member 93 as shown in fig. 25 (B). When the engagement portion 93a is engaged with the spacer 29, the chain engagement member 93 moves in the conveying direction as indicated by an arrow Pb in the figure as the continuous fastener chain 21 is conveyed.

Then, the slide member 89 integrated with the chain locking member 93 moves along the slide rail 87 against the elastic force of the spring 88, and the detection piece 90 fixed to the slide member 89 moves as indicated by an arrow Pc in the figure. When the detection piece 90 reaches the light detection region of the optical sensor 91, a detection signal from the detection piece 90 of the optical sensor 91 is output to a control unit, not shown. The control unit stops the conveyance of the continuous fastener chain 21 based on the detection signal.

The conveyance stop position of the continuous fastener chain 21 at this time is a welding position of the reinforcing film 31 by the anvil 263 and the ultrasonic horn 235 of the lower unit 205. That is, the arrangement position of the optical sensor 91 is set according to the relationship between the downstream end of the spacer 29 in the conveying direction and the arrangement position of the reinforcing film 31.

The above-described spacer portion 287 and distance detection portion 288 are fixed to the processing portion main body 201 side and are configured separately from the upper unit 203 and the lower unit 205. Therefore, even if the upper unit 203 and the lower unit 205 of various types are supported by the processing unit main body 201 at the time of machine setup, the partition portion 287 and the distance detection portion 288 are always accurately positioned with respect to the conveying path of the continuous fastener chain 21.

Since the sensor portions are not provided in the upper unit 203 and the lower unit 205, cables are not attached to the units. Therefore, there is no cable attachment/detachment work at the time of unit replacement, and cables do not become an obstacle. Further, since the cables connected to the sensor unit are provided on the processing unit main body 201 side, the cables are not stretched, bent, twisted, or rubbed during unit replacement. As a result, the deterioration of the cables over time is suppressed, and maintenance can be reduced. Further, since cables are not attached to each unit, the unit can be easily stored.

In the design of a typical manufacturing apparatus, it is preferable that a dedicated sensor unit be incorporated into a block-shaped unit having different specifications depending on the type of fastener chain and including main components, molds, and the like for performing the respective steps, and that positioning with respect to the continuous fastener chain be performed by assembling the unit itself, so that positional accuracy can be easily ensured. However, in the case where the continuous fastener chain is conveyed along the conveying path and different processes are performed at different positions on the conveying path, from the viewpoint of improving the accuracy and operability of the entire processes, it is desirable to ensure the positional accuracy on the manufacturing apparatus main body side as compared with the positional accuracy of the continuous fastener chain in the unit cells. That is, even if high positional accuracy is achieved in the unit itself, if the reference coordinate system of the manufacturing apparatus main body does not match the reference coordinate system of the unit itself with high accuracy when the unit is attached to the manufacturing apparatus main body, substantial accuracy improvement cannot be achieved. In order to match the reference coordinate systems with each other with high accuracy, a mechanism for accurately adjusting the units and a mechanism for manufacturing the apparatus main body are required, and the operation is complicated and requires experience.

The slide fastener manufacturing apparatus is different in positioning method, shape, component structure, size, weight, and assembly method depending on the type of slide fastener. Therefore, in the present configuration, the continuous fastener chain 21 is positioned by the sensor portion on the processing portion main body side, and the devices (main parts of processing, molds, and the like) for performing various kinds of processing on the continuous fastener chain 21 are separated from the processing portion main body and unitized. Therefore, the unit of this configuration only needs to have a positioning mechanism with respect to the processing portion main body, and there is no need to adjust the positioning with respect to each portion of the continuous fastener chain 21.

< mounting part processing part >

Next, the mounting portion processing portion 300 will be explained.

Fig. 26 is a perspective view of the mounting portion processed portion 300, and fig. 27 is an exploded perspective view of the mounting portion processed portion 300.

The mounting portion processing portion 300 includes a processing portion main body 301 and a punching unit 303. The punching unit 303 is prepared for each type of slide fastener 45 to be manufactured, and is detachable from the processing unit body 301.

The processing unit main body 301 includes a base plate 311, a pillar portion 313 and a unit mounting portion 315 provided on the base plate 311, a release mechanism portion 305 of the continuous fastener chain 21, and a driving portion 317. The punching unit 303 is attached to the unit attachment portion 315 from the front side. The release mechanism 305 is fixed to the base plate 311, and releases the continuous fastener chain 21 to the piercing unit 303. Further, the drive section 317 disposed above the support section 313 of the processing section main body 301 drives the punching unit 303.

A sensor portion, which will be described later, for detecting the presence and position of the continuous fastener chain 21 to be fed out is provided in a unit attachment portion 315 which is fixed to the processing portion main body 301 side and provided separately from the piercing unit 303.

Fig. 28 is a side view of the punching unit 303 shown in fig. 27, viewed from the direction of V3.

The punching unit 303 includes a bottom plate 321, a top plate 323, a support 325, and a processing mechanism 327. The bottom plate 321 and the top plate 323 are each a rectangular plate in plan view, and are arranged with a space in the vertical direction by 4 support columns 325. The base plate 321 has a width Wc and a thickness tc. Biasing members such as springs are provided inside the respective support columns 325. The top plate 323 is biased upward away from the bottom plate 321 by a biasing member in the support column 325.

The machining mechanism 327 includes a support 331 provided on the top plate 323, a lower mold 333 provided on the bottom plate 321, and a tool 337. A guide member 345 is disposed between the support portion 331 and the lower mold portion 333. A guide pin 335 for coupling the support portion 331 and the lower mold portion 333 is inserted into the guide member 345, and the guide pin 335 is fixed to the top plate 323 by a pin not shown. The guide member 345 has a guide hole into which a tool tip portion, which will be discussed later, of the tool portion 337 is inserted, and each tool is slidably guided in the vertical direction.

Fig. 29 is a schematic side view showing a main part of the mounting portion processed portion 300 in a partial cross section.

The tool portion 337 has a punching punch 341 and a windowing punch 343. The punching punch 341 is a tool for forming the hole 33 shown in fig. 2 (C), and the windowing punch 343 is a tool for forming the window 35 shown in fig. 2 (C).

The punching punch 341 and the windowing punch 343 are slidably supported by a guide member 345 disposed above the lower die part 333. Further, a punching die 347 into which the punching punch 341 is inserted and a window die 349 into which the window punch 343 is inserted are formed in the lower die part 333. Between the guide member 345 and the lower mold part 333, a conveying path of the continuous fastener chain 21 released by the release mechanism 305 shown in fig. 26 is formed. When the distance portion reaches below the tool portion 337, the continuous fastener chain 21 is stopped from being conveyed, and the tool portion 337 performs punching and windowing. This forms hole 33 and window 35 shown in fig. 2 (C).

As shown in fig. 27, the unit mounting portion 315 includes a mounting table 353 above the pair of blocks 351. A pair of support grooves 355 facing each other are formed on the side of the mounting/dismounting table 353. The pair of support grooves 355 are formed along the mounting direction (Y direction) of the punching unit 303 to the processing portion main body 301.

Fig. 30 is a sectional view schematically showing a state in which the bottom plate 321 of the punching unit 303 is attached to the unit attachment portion 315.

The distance Wd between the bottoms 357 in the pair of support grooves 355 is slightly larger than the width Wc of the bottom plate 321 of the punching unit 303. The gap td, which is the vertical groove width of the support groove 355, is slightly larger than the thickness tc of the bottom plate 321 of the punching unit 303. As shown in fig. 27, a stopper 361 is fixed to an end surface of the block 351 on the Y-direction rear side.

When the punching unit 303 is attached to the processing unit main body 301, both side edges of the bottom plate 321 of the punching unit 303 are inserted into the support grooves 355 from the front side of the processing unit main body 301 on the attaching and detaching table 353 of the unit attaching portion 315. Then, the punching unit 303 is pushed in until the bottom plate 321 abuts against the side surface of the stopper 361. At this time, the bottom plate 321 is engaged with the support groove 355, whereby the punching unit 303 is positioned in the conveying direction (X direction) and the vertical direction (Z direction) of the continuous fastener chain 21. Further, the bottom plate 321 abuts against the outer peripheral portion of the stopper 361, whereby the punching unit 303 is positioned in the unit attachment direction (Y direction) (see fig. 26).

In this way, in the unit mounting portion 315 (the processing portion side positioning portion) of the processing portion main body 301, the bottom portion 357 of the support groove 355, the inner surface of the support groove 355 including the upper surface of the attaching and detaching table 353, and the contact surface of the stopper 361 with the bottom plate 321 support the bottom plate 321. Thus, the unit mounting portion 315 and the bottom plate 321 function as a positioning portion that restricts movement of the punching unit 303 and positions the punching unit.

After the punching unit 303 is attached to the unit attachment portion 315, as shown in fig. 26, the fixing member 365 is fixed to one block 351 serving as the attaching and detaching table 353 by a fixing bolt 367. Thus, the bottom plate 321 of the punching unit 303 is locked to the fixing member 365, and the punching unit 303 is maintained in the state of being attached to the unit attaching portion 315.

In the mounting portion processing portion 300, as shown in fig. 29, the continuous fastener chain 21 released by the releasing mechanism portion 305 shown in fig. 26 is disposed between the guide member 345 of the processing mechanism portion 327 and the lower mold portion 333. In the spacer portion 29 of the continuous fastener chain 21 shown in fig. 2 (B), a portion where the reinforcing film 31 is deposited is disposed directly below the processing mechanism portion 327.

When the driving portion 317 shown in fig. 26 of the processing unit main body 301 is driven in this state, the support column 325 contracts in accordance with the pressing of the driving portion 317 against the top plate 323, and the top plate 323 descends. As the top plate 323 descends, the punching punch 341 and the windowing punch 343 shown in fig. 29 descend. Then, the punching punch 341 and the windowing punch 343 penetrate the continuous fastener chain 21 and are inserted into the punching die 347 and the windowing die 349 of the lower die part 333.

In this way, the attaching portion 37 having the hole portion 33 and the window portion 35 shown in fig. 2 (C) is processed in the space portion 29 of the continuous fastener chain 21 to which the reinforcing film 31 is applied.

In the attachment portion processing portion 300, when manufacturing a different type of slide fastener 45, the punching unit 303 attached to the processing portion main body 301 is replaced with a punching unit 303 corresponding to the slide fastener 45 to be manufactured next.

When the punching unit 303 is detached from the processing unit main body 301, the fixing member 365 is detached by loosening the fixing bolt 367, and the punching unit 303 is pulled out to the front side so as to pull out the bottom plate 321 from the support groove 355. Thereby, the punching unit 303 is easily detached from the processing unit main body 101.

In addition, when the punching unit 303 corresponding to the subsequent manufacturing is assembled to the processing unit main body 301, the positioning can be accurately performed in the conveying direction (X direction), the unit attaching direction (Y direction), and the vertical direction (Z direction) of the continuous fastener chain 21 by the simple operation as described above, and the time for the setup change can be significantly reduced. Further, since the setup change is performed without requiring the operator's skill, the setup change can be quickly applied to the production of various product types, and a production line with improved production efficiency can be constructed at low cost.

Next, a sensor unit provided in the processing unit main body 301 will be described.

Fig. 31 is an enlarged perspective view of the release mechanism 305 of the processing unit main body 301.

The conveying path of the continuous fastener chain 21 is formed between a lower rail 371 that supports the lower side of the continuous fastener chain and an upper rail 373 that is disposed above the lower rail 371 with the continuous fastener chain interposed therebetween.

The feeding mechanism 305 is provided with a spacer detecting section 375 (shown in detail in fig. 32) below the conveying path of the continuous fastener chain 21, and a distance detecting section 377 for detecting the distance from the end of the spacer is provided above the conveying path.

The distance detecting unit 377 has the same configuration as the distance detecting unit 288 (see fig. 23) of the ejection mechanism 207 described above. That is, the distance detecting unit 377 includes a fixing plate 379, a slide rail 381, a slide member 383, a detecting piece 385, an optical sensor 387, and a chain locking member 389. The fixing plate 379 is fixed to the processing unit body 301 (see fig. 27), and the slide rail 381 is fixed to the fixing plate 379. The slide member 383 is supported movably by the slide rail 381, and is biased by a spring, not shown, to be extended along the slide rail 381 toward the back side in the X direction. A detection piece 385 is fixed above the slide member 383, and a chain locking member 389 is fixed below the slide member 383. The detection piece 385 is formed of a plate material provided to a part of the slide member 383. The chain locking member 389 has a locking portion 389a (see fig. 32) protruding downward at a distal end thereof. The photosensor 387 is disposed so as to sandwich a part of the detection piece 385, and is fixed to a member on the processing unit main body 301 side.

Fig. 32 is an explanatory diagram showing the operation of the spacer detection unit 375 and the distance detection unit 377.

The spacer detector 375 on the lower side of the conveyance path includes a swing lever 391 supported to be swingable about a fulcrum 391a, a rotary disk 393, a detection piece 395, and an optical sensor 397.

The operation of the spacer detection unit 375 and the distance detection unit 377 is the same as that of the configuration shown in fig. 25 (a) and (B). That is, the swing of the swing lever 391 caused by the displacement of the rotating disk 393 is detected by the optical sensor 397. Further, the downstream end in the conveying direction in the spacer section 29 of the continuous fastener chain 21 is locked by the locking section 389a of the chain locking member 389, and moves in the conveying direction as indicated by an arrow Pb in the figure. The movement of the chain locking member 389 is detected by the optical sensor 387.

The conveyance stop position of the continuous fastener chain 21 is controlled by the detection signals from the

optical sensors

387, 397 serving as the position detection sensors, and the reinforcing film 31 shown in fig. 2 (B) is disposed just below the tool portion 337 shown in fig. 29. Then, by pressing down the tool portion 337, the hole portion 33 and the window portion 35 are formed at the formation position of the through hole of the continuous fastener chain 21.

The spacer detection unit 375 and the distance detection unit 377 as sensor units are fixed to the processing unit main body 301 and are configured separately from the punching unit 303. Therefore, even if the various punching units 303 are supported by the processing unit main body 301 during the machine setup, the spacer detection section 375 and the distance detection section 377 are always accurately positioned with respect to the conveyance path of the continuous fastener chain 21.

According to the zipper manufacturing apparatus described above, in each of the

processing sections

100, 200, and 300, the

units

103, 105, 203, 205, and 303 are replaceable with respect to the processing section

main bodies

101, 201, and 301. Therefore, the work of changing the production and adjustment when manufacturing different slide fasteners is enough to replace only the

units

103, 105, 203, 205, 303. Therefore, it is possible to easily cope with the manufacture of different types of slide fasteners in a short time. That is, by attaching the

unit

103, 105, 203, 205, 303 to the processing portion

main body

101, 201, 301, the

unit

103, 105, 203, 205, 303 is accurately positioned to the processing portion

main body

101, 201, 301. Thus, the setup change can be performed without requiring a detailed position adjustment work or the like and without requiring thorough training. Therefore, compared to the case where a dedicated manufacturing apparatus having a dedicated mechanism is used for each type of slide fastener to be manufactured, the number of manufacturing apparatuses can be reduced, the operating rate of one manufacturing apparatus can be increased, and the facility cost and the running cost can be reduced.

Further, by preparing a plurality of units for manufacturing the same type of slide fastener, even if a failure occurs in a unit in use, it is sufficient to replace only the failed unit, and the production line can be quickly re-operated.

In the slide fastener manufacturing apparatus of the present configuration, the

processing units

100, 200, and 300 such as the spacer processing unit 100, the reinforcing film welded processing unit 200, and the attachment processing unit 300 are provided with sensor units for detecting the presence or absence and position of the continuous fastener chain 21 on the side of the

processing unit bodies

101, 201, and 301. Meanwhile, the driving

units

117, 219, 317 for performing processing on the continuous fastener chain 21 are provided on the processing unit

main bodies

101, 201, 301. The sensor portion and the driving portion are not present on the side unitized like the upper unit 103, the lower unit 105, the upper unit 203, the lower unit 205, the punching unit 303, and the like.

In this way, by providing the sensor unit and the drive unit on the processing unit main body side of each of the

processing units

100, 200, and 300, even when a large number of units are used, the production facility can be realized at low cost. That is, each unit can be operated using the same sensor unit and the same driving unit, so that the unit can be easily designed and managed, and the maintainability is improved. Further, since the signal line, various pipes, and the like are not connected to the unit side that is replaceable, the handling property of the unit itself is improved, and the operability and the storage property can be improved. Further, since the lubricant, the cleaning agent, and the like necessary for rust prevention, stain prevention, and foreign matter removal can be used on the unit side without taking the sensor unit and the driving unit into consideration, maintenance and management of the unit are facilitated.

The pretreatment device 3 having the above-described configurations includes a spacer processing section 100, a reinforcing film welding processing section 200, and an attachment processing section 300, which fasten the

units

103, 105, 203, 205, and 303, such as the upper unit 103, the lower unit 105, the upper unit 203, the lower unit 205, and the piercing unit 303, with fixing

bolts

143, 193, 243, 271, and 367. All of the fixing

bolts

143, 193, 243, 271, 367 are fastening members having the same standard size, that is, the nominal size of the screw thread such as "M8", for example, and can be fastened and unfastened by a common tool. Examples of the fastening member include a hexagon socket bolt and a bolt nut. For a common tool, for example in the case of a hexagon wrench, a spanner, it means that the side-to-side distances are of the same size.

In order to distinguish from bolts and screws for fixing other portions, the fixing

bolts

143, 193, 243, 271, 367 for fastening the units are preferably made of the same color (for example, primary colors such as red and yellow, gold, fluorescent colors, and the like, which are excellent in visibility).

Since the fixing

bolts

143, 193, 243, 271, 367 can be fastened by a common tool, the worker does not need to replace the tool for each unit when performing the setup change, thereby improving the work efficiency. Further, by unifying the same color, the worker can easily visually recognize the position of the bolt to be attached or detached when performing the setup change. This eliminates the occurrence of erroneous work such as erroneous removal of a bolt or a screw, forgetting to remove the bolt or the screw, or forgetting to attach the bolt or the screw, and thus can complete necessary work quickly and reliably.

It is preferable that the

units

103, 105, 203, 205, and 303 are stored, managed, and identified by assigning the same number, the same symbol, and the same color identifier to each type of the size, the specification, and the like of the slide fastener 45 to be manufactured. For example, a seal on which a corresponding symbol is recorded or a seal of a corresponding color is preferably attached to the manufacturing apparatus main body and each unit. This makes it difficult for an operator to make a mistake and makes it possible to easily perform a confirmation operation. Further, instead of the sticker, painting with a specific color or the like may be performed.

As described above, the present invention is not limited to the above-described embodiments, and a configuration in which the respective configurations of the embodiments are combined with each other, and a configuration in which a person skilled in the art performs modification and application based on the description of the specification and a well-known technique are also a predetermined configuration of the present invention, and are included in the scope of the claims.

For example, the positioning portions are not limited to the configurations shown in the drawings, and any configuration may be adopted as long as the unit attached to the processing unit main body can be positioned with respect to the processing unit main body in the direction orthogonal to the conveying direction of the continuous fastener chain and the direction along the conveying direction.

In addition, although the present continuous fastener chain exemplifies a resin fastener chain having resin-made fastener elements, a metal fastener chain having metal-made fastener elements may be used. In this case, unlike the resin slide fastener, the spacer 29 (see fig. 2) is provided in advance and the metal element is attached to the tape, so that the spacer processing part 100 is not necessary.

The sensor element used in the sensor unit is not limited to the detection roller and the optical sensor described above, and may be a sensor of another type. Various sensors such as a magnetic sensor, a pressure sensor, and a photoelectric sensor, a microswitch, and the like can also be used.

In addition, a common plug may be provided for each type of unit, and a connector that engages with only the plug of the unit to be attached may be provided in the processing portion body. In this case, when the worker erroneously mounts the unit, the plug of the unit does not engage with the connector of the processing unit main body, and therefore, the worker can recognize that the unit is erroneously mounted.
