When the fixing bolt 271 is inserted through the insertion hole 269, a radial gap is formed between the inner peripheral surface and the fixing bolt 271, so that the second lower unit 205 has a slight position adjustment margin. The second lower unit 205 is fixed to the processing unit body 201 by screwing the fixing bolt 271 to the screw hole 285.

In this reinforced film welding machine part 200, the second The unwinding mechanism section 207 between the upper unit 203 and the second lower unit 205 feeds the continuous fastener chain 21. The reinforcing film 31 shown in FIG. 2 (B) is supplied from a suitable reinforcing film supply mechanism (not shown) to the take-up mechanism section 207. The reinforcing film supply mechanism arranges a reinforcing film 31 on the space portion 29 of the continuous zipper chain 21 being conveyed.

In this state, if the unit block 231 is lowered by the up-and-down driving unit 219 of the processing unit body 201 shown in FIG. 16, as shown in FIG. 22, the ultrasonic welding head 235 is supplied from a reinforcing film supply mechanism (not shown). And abuts on the reinforcing film 31 disposed on the space portion 29. Thereby, the space portion 29 of the continuous fastener chain 21 is sandwiched between the ultrasonic horn 235 of the second upper unit 203 and the anvil 263 of the second lower unit 205 via the reinforcing film 31. When the ultrasonic welding head 235 is subjected to ultrasonic vibration by the ultrasonic generator in this state, the reinforcing film 31 is welded to the space portion 29 of the continuous fastener chain 21 by frictional heat caused by the ultrasonic vibration.

In the reinforcement film welding processing unit 200, when the installation and replacement of different types of zippers 45 are changed, the second upper unit 203 and the second lower unit 205 attached to the processing unit body 201 shown in FIG. 16 are changed to the next one. The manufactured zipper 45 corresponds to a combination of an ultrasonic horn 235 or an anvil 263.

When the second upper unit 203 is detached from the processing unit main body 201, the fixing bolt 243 that fastens the second upper unit 203 to the upper unit mounting portion 215 of the processing unit main body 201 is loosened to release the fastening. This allows the second upper unit 203 to be easily removed from the processing unit body 201. When the second lower unit 205 is removed from the processing unit main body 201, the fixing bolt 271 that fastens the second lower unit 205 to the lower unit mounting portion 217 of the processing unit main body 201 is loosened and released. Accordingly, the second lower unit 205 can be easily removed from the processing unit body 101.

In addition, when the second upper unit 203 and the second lower unit 205 corresponding to the next manufacturing are assembled to the processing unit body 201, as described above, it can be accurately positioned in the conveying direction (X by simple operations). Direction), up and down direction (Z direction), unit mounting direction (Y direction). As a result, the time for setting replacement can be significantly reduced. In addition, since the skilled worker's experience is not required during installation and replacement, it can respond to the production of a wide variety of products quickly, and a production line with improved production efficiency can be constructed at low cost.

The second upper unit 203 and the second lower unit 205 are fixed to the processing unit body 201 from the front direction of the processing unit body 201 by fixing bolts 243 and 271. In this way, the unit can be fixed from the front direction or the upside direction of the main body of the processing unit, thereby realizing work efficiency and shortening the time when the unit is replaced.

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

FIG. 23 is a perspective view showing the configuration of the unwinding mechanism section 207 of the processing section body 201.

The unwinding mechanism section 207 is provided with a space detection section 287 above the conveyance path of the continuous fastener chain 21, and a distance detection section 288 is provided below the conveyance path to detect the distance from the end of the space section. The space detection unit 287 and the distance detection unit 288 function as a sensor unit that detects the transport position of the continuous fastener chain 21.

The conveying path of the continuous zipper chain 21 is formed between the lower rail 289 and the upper rail 290. The lower rail 289 supports the lower side of the continuous zipper chain 21. The upper rail 290 is disposed on the lower guide through the continuous zipper chain 21. Above the rail 289.

The space detection unit 287 includes a rail support portion 73, a jog lever 75, a rotating disk 77, a detection piece 79, and a light sensor 81 as a position detection sensor. The guide rail support portion 73 is erected from the lower guide rail 289 and supports the upper guide rail 290 so as to be movable up and down by the elastic force of the spring 71. The swing lever 75 is rotatably supported on the upper rail 290 with the fulcrum 75a as a center, and is biased in one direction (clockwise direction in FIG. 23) by the compression spring 74. The rotary disk 77 is supported at one end portion of the swing lever 75 and has a plate thickness that is smaller than the width of the space 29 (see FIG. 2 (A)) of the continuous zipper chain 21 orthogonal to the conveying direction. A detection piece 79 including an L-shaped plate is provided at the other end of the swing lever 75. The light sensor 81 as a position detection sensor is fixed to a fixed side (not shown) with a part of the detection sheet 79 therebetween, and detects whether or not the detection sheet 79 has moved.

The distance detection unit 288 includes a fixed plate 85, a slide rail 87, a slide member 89, a detection piece 90, a light sensor 91 as a position detection sensor, and a chain locking member 93. The fixed plate 85 is provided in a state of being fixed to the processing unit body 201 (see FIG. 17), and the slide rail 87 is fixed to the fixed plate 85. The sliding member 89 is movably supported by the sliding guide 87, and is stretched and biased in the left direction in the drawing by a spring 88 along the sliding guide 87. A detection piece 90 including 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 93 a protruding upward at the front end. The light sensor 91 as a position detection sensor is fixed to a member on the processing unit body 201 side such as a fixed plate 85 via a front end portion extending from the sliding member 89 of the detection piece 90.

25 (A) and 25 (B) show the space part detection unit in stages. An operation explanatory diagram of the operations of 287 and the distance detection unit 288.

As shown in FIG. 25 (A), when the continuous zipper chain 21 is conveyed on the conveyance path between the lower rail 289 and the upper rail 290, the rotary disk 77 rotates while abutting on the continuous zipper chain 21. When the space portion 29 of the continuous fastener chain 21 reaches directly below the rotating disk 77, the rotating disk 77 fits into the opening of the space portion 29. Then, the jog lever 75 moves as shown by the arrow Pa in the figure, and the detection piece 79 deviates from the light detection area of the light sensor 81 as the position detection sensor. The light sensor 81 as a position detection sensor outputs a detection signal to a control unit (not shown). Based on the input detection signal, the control unit detects the timing at which the detection piece 79 deviates from the light detection area as the timing when the space portion 29 of the continuous fastener chain 21 has arrived.

Furthermore, when the continuous fastener chain 21 is conveyed, as shown in FIG. 25 (B), the downstream end of the space portion 29 in the conveying direction is locked to the locking portion 93 a of the chain locking member 93. When the locking portion 93a is locked in the space portion 29, the chain locking member 93 moves along the conveying direction as shown by an arrow Pb in the figure as the continuous zipper 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 shown by arrow Pc in the figure. When the detection piece 90 reaches the light detection area of the light sensor 91 as the position detection sensor, the detection signal from the detection piece 90 of the light sensor 91 as the position detection sensor is output to an unillustrated Control department. The control unit stops the conveyance of the continuous fastener chain 21 based on the detection signal.

The conveyance stop position of the continuous zipper chain 21 at this time is the welding position of the anvil 263 and the ultrasonic welding head 235 of the second lower unit 205 to the reinforcing film 31. Home. That is, the arrangement position of the light sensor 91 as the position detection sensor is set in accordance with the relationship between the downstream end in the conveyance direction of the space portion 29 and the arrangement position of the reinforcing film 31.

The space detection unit 287 and the distance detection unit 288 are both fixed to the processing unit body 201 side, and are separated from the second upper unit 203 and the second lower unit 205. Therefore, even if the second upper unit 203 or the second lower unit 205 of each type is supported by the processing unit body 201 during the installation and replacement, the space detection unit 287 and the distance detection unit 288 can maintain the continuous transportation to the continuous fastener chain 21 The state of the accurate positioning of the path.

In addition, since the sensor unit is not provided in the second upper unit 203 and the second lower unit 205, it is not necessary to attach a cable to each unit. Therefore, no cable loading and unloading work is performed when the unit is replaced, so that cables are not an obstacle. In addition, since the cables connected to the sensor section are provided on the processing section body 201 side, the cables will not be stretched, bent, twisted, or rubbed during unit replacement. As a result, deterioration of the cables and the like can be suppressed and maintenance can be reduced. In addition, since each unit is not provided with a cable, it is easy to store the unit.

In the design of a general manufacturing device, the specifications are different for each zipper type. In a block-shaped unit including the main parts or molds for performing each step, a sensor unit dedicated to the unit is assembled and continuously The alignment of the zipper chain can easily ensure the position accuracy and is better. However, in the case where the continuous zipper chain is carried along the conveying path and different steps are performed at different positions on the conveying path, the position accuracy of the continuous zipper chain can be ensured on the main body side of the manufacturing device rather than the position accuracy of the continuous zipper chain in a single unit Improve the accuracy and workability of the entire process Ideal from a viewpoint. That is, even if high position accuracy is achieved in a single unit, when the unit is mounted on the manufacturing device body, if the reference coordinate system of the manufacturing device body and the reference coordinate system of the single unit are not accurately matched, substantial accuracy improvement cannot be achieved. . In order to make the reference coordinate systems coincide with each other with high accuracy, it is necessary to accurately adjust the mechanism of the unit and the mechanism of the manufacturing apparatus body, and this operation is complicated and requires experience.

In the slide fastener manufacturing apparatus, there are positioning methods, shapes, component configurations, sizes, weights, and assembly methods that differ depending on the type of the slide fastener. Therefore, in this configuration, the continuous zipper chain 21 is positioned using the sensor section on the processing section body side, and the machine (the main part or mold processed) for various processing of the continuous zipper chain 21 is processed from the processing section body Cut and unitize. Therefore, the unit of this configuration only needs to have a positioning mechanism for the processing unit body, and it is not necessary to perform positioning adjustment for each part of the continuous fastener chain 21.

FIG. 30 is a cross-sectional view schematically showing a mounting state of the bottom plate 321 of the perforated unit 303 to the unit mounting portion 315.

The interval Wd between the bottom portions 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. Further, the gap width td in the vertical direction of the support groove 355 is slightly larger than the thickness tc of the bottom plate 321 of the punching unit 303. Further, as shown in FIG. 27, a stopper 361 is fixed to an end surface on the back side in the Y direction of the block 351.

When the punching unit 303 is mounted on the processing unit body 301, the mounting and unloading table 353 of the unit mounting portion 315 faces each support groove from the front side of the processing unit body 301 355 is inserted into both side edges of the bottom plate 321 of the punching unit 303. Then, the punching unit 303 is pushed in until the bottom plate 321 abuts the side surface of the stopper 361. At this time, the punching unit 303 is engaged with the support groove 355 by the bottom plate 321, and is positioned in the carrying direction (X direction) and the up-down direction (Z direction) of the continuous zipper chain 21. The punching unit 303 is positioned in the unit mounting direction (Y direction) by the bottom plate 321 abutting against the outer peripheral portion of the stopper 361 (see FIG. 26).

In this way, in the unit mounting portion 315 (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 mounting table 353, the stopper 361, and the bottom plate 321 The abutting surface supports the bottom plate 321. Thereby, the unit mounting portion 315 and the bottom plate 321 function as a positioning portion that restricts the positioning of the perforation unit 303 and moves.

After the perforated unit 303 is attached to the unit mounting portion 315, as shown in FIG. 26, a fixing member 365 is fixed to a block 351 that becomes the loading / unloading stand 353 by a fixing bolt 367. Thereby, the bottom plate 321 of the punching unit 303 is locked to the fixing member 365, and the state in which the punching unit 303 is mounted on the unit mounting portion 315 is maintained.

As shown in FIG. 29, in the mounting portion processing portion 300, a continuous zipper unrolled by the unwinding mechanism portion 305 shown in FIG. 26 is arranged between the guide member 345 of the processing mechanism portion 327 and the lower die portion 333.

When the punching unit 303 is removed from the processing unit body 301, the fixing bolt 367 is loosened to remove the fixing member 365, and the punching unit 303 is pulled out to the front side by pulling the bottom plate 321 from the support groove 355. Thereby, the punching unit 303 can be easily removed from the processing unit body 101.

In addition, when the punching unit 303 corresponding to the next manufacturing is assembled in the processing unit body 301, as described above, the transport direction (X direction) and the unit mounting direction of the continuous zipper chain 21 can be performed by a simple operation. (Y direction) and up and down direction (Z direction) accurate positioning can greatly reduce the time for setting replacement. In addition, since the skilled worker's experience is not required during installation and replacement, it can respond to the production of a wide variety of products quickly, and a production line with improved production efficiency can be constructed at low cost.

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

FIG. 31 is an enlarged perspective view of the unwinding mechanism section 305 of the processing section body 301.

The conveying path of the continuous zipper chain 21 is formed between a lower rail 371 and an upper rail 373. The lower rail 371 supports the lower side of the continuous zipper chain. The upper rail 373 is disposed above the lower rail 371 via the continuous zipper chain. .

That is, the distance detection unit 377 includes a fixed plate 379, a slide guide 381, a slide member 383, a detection piece 385, a light sensor 387 as a position detection sensor, and a chain locking member 389. The fixing plate 379 is provided in a state of being fixed to the processing unit body 301 (see FIG. 27), and the slide rail 381 is fixed to the fixing plate 379. The sliding member 383 is movably supported by the sliding guide 381, and is stretched and urged along the sliding guide 381 by a spring (not shown) toward the far side in the figure in the X direction. A detection piece 385 is fixed above the sliding member 383, and a chain locking member 389 is fixed below the sliding member 383. The detection piece 385 includes a plate material provided on a part of the sliding member 383. The chain locking member 389 has a locking portion 389 a (see FIG. 32) protruding downward from the front end. A light sensor 387 as a position detection sensor is disposed with a part of the detection piece 385 interposed therebetween, and is fixed to a member on the processing unit body 301 side.

FIG. 32 is an operation explanatory diagram showing operations of the space detection unit 375 and the distance detection unit 377.

The space part detection unit 375 below the conveyance path includes a fulcrum 391a A jog lever 391, a rotating disk 393, a detection piece 395, and a light sensor 397 serving as a position detection sensor are supported so as to be supported by the center.

The operations of the space detection unit 375 and the distance detection unit 377 are the same as those in the configuration shown in FIGS. 25 (A) and 25 (B). That is, the movement of the jog lever 391 caused by the displacement of the rotating disk 393 is detected by the light sensor 397 as a position detection sensor. The downstream end of the space portion 29 of the continuous fastener chain 21 in the conveying direction is locked to the locking portion 389a of the chain locking member 389 and moves in the conveying direction as shown by an arrow Pb in the figure. The movement of the chain locking member 389 is detected by a light sensor 387 as a position detection sensor.

With the detection signals from the light sensor 387 as the position detection sensor and the light sensor 397 as the position detection sensor, the conveyance stop position of the continuous zipper chain 21 is controlled. In the tool section shown in FIG. 29 A reinforcing film 31 shown in FIG. 2 (B) is arranged directly below 337. Further, by pushing the tool portion 337 downward, a hole portion 33 and a window portion 35 for the hole are formed in the formation position of the hole in the continuous fastener chain 21.

The space part detection part 375 and the distance detection part 377 as the sensor part are both fixed to the processing part body 301 side, and are configured separately from the punching unit 303. Therefore, even when the various perforating units 303 are supported by the processing unit body 301 when the setting is changed, the space detection unit 375 and the distance detection unit 377 can maintain a state of being accurately positioned with respect to the transport path of the continuous zipper chain 21 at all times.

According to the above-described zipper manufacturing apparatus, in each of the space portion processing portion 100, the reinforcement film welding processing portion 200, and the mounting portion processing portion 300, the first upper unit 103, The first lower unit 105, the second upper unit 203, the second lower unit 205, and the punching unit 303 are freely replaceable with respect to the processing unit body 101, the processing unit body 201, and the processing unit body 301. Therefore, only the first upper unit 103, the first lower unit 105, the second upper unit 203, the second lower unit 205, and the punching unit 303 may be replaced during the installation and replacement operation when manufacturing different slide fasteners. This makes it possible to cope with the manufacture of different types of slide fasteners simply and in a short time. That is, the first upper unit 103, the first lower unit 105, the second upper unit 203, the second lower unit 205, and the punching unit 303 are attached to the processing unit body 101, the processing unit body 201, and the processing unit body 301. The 1 upper unit 103, the first lower unit 105, the second upper unit 203, the second lower unit 205, and the perforation unit 303 can be accurately positioned in the processing unit body 101, the processing unit body 201, and the processing unit body 301. This eliminates the need for fine position adjustment work and the like, and does not require skilled experience to perform setting replacement. As a result, the number of manufacturing devices can be reduced, the operating rate of one manufacturing device can be increased, and the equipment costs and operating costs can be reduced compared to the case of using a dedicated manufacturing device having a dedicated mechanism for each zipper to be manufactured.

In addition, by preparing a plurality of units for manufacturing the same type of zipper, even if the unit in use fails, it is only necessary to change the unit that has failed, and the production line can be quickly operated again.

Furthermore, according to the zipper manufacturing device of this configuration, each of the space part processing sections 100 such as the space processing section 100, the reinforcement film welding processing section 200, and the mounting section processing section 300, the reinforcement film welding processing section 200, and the mounting section processing section 300 will A sensor section that detects the presence or absence of the continuous zipper chain 21 is provided in the processing section body 101 and the processing section The body 201 and the processing unit body 301 side.

In addition, a sensor portion or a driving portion does not exist on the unitized side such as the first upper unit 103, the first lower unit 105, the second upper unit 203, the second lower unit 205, and the punching unit 303.

In this way, by providing a sensor portion or a driving portion on the processing portion body side of each of the space portion processing portion 100, the reinforcement film welding processing portion 200, and the mounting portion processing portion 300, it is possible to use even a plurality of units. Low-cost implementation of production equipment. That is, each unit can be operated by using the same sensor unit and the same driving unit, and the design and management of the unit becomes easy, and the maintainability is improved. Furthermore, since the signal line, various piping, etc. are not connected to the freely replaceable unit side, the handling property of the unit itself is improved, and workability or storageability can be improved. In addition, since the sensor portion or the driving portion can be unaware of the use of the lubricant or cleaning agent required for rust prevention, dirt prevention, or removal of foreign matter on the unit side, maintenance and management of the unit becomes easy.

In addition, the space part processing section 100, the reinforcement film welding processing section 200, and the mounting section processing section 300 constituting the pre-processing device 3 of the above-mentioned respective configurations include the first upper unit 103, the first lower unit 105, the second upper unit 203, Each of the first upper unit 103, the first lower unit 105, the second upper unit 203, the second lower unit 205, and the piercing unit 303, such as the second lower unit 205 and the perforation unit 303, is fixed by a fixing bolt 143, a fixing bolt 193, and a fixing bolt. 243.
