It is gripped by the gripping portion 153 of the unit 105. When the drive 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. Then, the pin 127 at the tip of the piston 123 protrudes 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 pins 127. Thereby, as shown to FIG. 2 (A), the space part 29 is formed in the continuous fastener chain 21. As shown in FIG.

The continuous fastener chain 21 is drawn out by a transport driving unit (not shown) and transported on a transport path. The moving amount of the continuous fastener chain 21 is measured by the measuring roll of the sensor unit 119. The transport of the continuous fastener chain 21 is controlled based on the measurement result of the movement amount, and the space portion 29 is formed by the above-described operation at the cutting position of the desired fastener element in the continuous fastener chain 21.

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

In addition to the measuring roll, other sensors may be provided in the processing unit main body 101. By fixing the sensor unit 119 and the other sensors on the processing unit main body 101 side, the continuous fastener chain 21 is always measured by the same sensor unit in the conveyance paths of the lower units 105 of multiple types even at the time of setup change. Therefore, the repeatability of measurement is enhanced, and stable high-precision manufacturing can be realized.

In this way, positioning with respect to each part of the continuous fastener chain which is a workpiece is performed on the processing unit main body side, and on the unit side, positioning is performed to match the reference coordinate system of the unit itself with the reference coordinate system of the processing unit main body By providing the structure, the unit replacement, that is, the setup replacement operation can be made much more efficient while maintaining high positional accuracy. As a result, it is possible to shorten the work time of setup change, and to construct a production line that can quickly cope with various types of slide fasteners.
The above-described effects can be obtained in the same way in the subsequent steps.

Then, when the space portion 29 of the continuous fastener chain 21 reaches immediately below the rotary disk 77, the rotary disk 77 is fitted into the opening of the space portion 29. Then, the swing lever 75 swings as shown by the arrow Pa in the figure, and the detection piece 79 is out of the light detection area of the light sensor 81. The light sensor 81 outputs a detection signal to a control unit (not shown). The control unit detects the timing at which the detection piece 79 deviates from the light detection area, as the timing at which the space portion 29 of the continuous fastener chain 21 has arrived, based on the input detection signal.

Furthermore, when the continuous fastener chain 21 is transported, the downstream end in the transport direction of the space portion 29 is locked to the locking portion 93a of the chain locking member 93, as shown in FIG. 25 (B). When the locking portion 93 a is locked in the space portion 29, the chain locking member 93 is moved along the transport direction as shown by the arrow Pb in the figure as the continuous fastener chain 21 is transported.

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 is an arrow in the figure. Move as shown by Pc. When the detection piece 90 reaches the light detection region of the light sensor 91, a detection signal of the detection piece 90 from the light 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 the welding position of the reinforcing film 31 by the anvil 263 and the ultrasonic horn 235 of the lower unit 205 described above. That is, the arrangement position of the light sensor 91 is set in accordance with the relationship between the downstream end of the space portion 29 in the conveyance direction and the arrangement position of the reinforcing film 31.

The space detection unit 287 and the distance detection unit 288 described above are both fixed to the processing unit 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 setup change, the space detection unit 287 and the distance detection unit 288 always always carry the conveying path of the continuous fastener chain 21. The precisely positioned state is maintained.

In addition, the upper unit 203 and the lower unit 205 are not provided with a sensor unit, and accordingly, cables are not attached to each unit. Therefore, there is no cable attachment and detachment work at the time of unit exchange, and cables do not get in the way. And since cables etc. which are connected to a sensor part are installed in processing part main part 201 side, at the time of unit exchange, cables are not made to produce tension, bending, twist, rubbing, etc. As a result, aging deterioration of cables can be suppressed, and maintenance can be reduced. In addition, since cables are not attached to each unit, the units can be easily stored.

In the design of a typical manufacturing device, the specifications differ for each fastener type, and a dedicated unit is attached to the unit itself in a block unit including main parts and molds for carrying out each process It is preferable to perform alignment with the fastener chain, because the positional accuracy can be easily secured. However, when the continuous fastener chain is transported along the transport path and different processes are performed at different positions on the transport path, the manufacturing device main body side is more than securing the positional accuracy of the continuous fastener chain with the unit alone. It is desirable from the viewpoint of improving the accuracy and operability of the whole process to secure the positional accuracy. That is, even if the unit alone achieves high positional accuracy, when the unit is mounted on the manufacturing apparatus main body, the reference coordinate system of the manufacturing apparatus main body and the reference coordinate system of the unit itself do not match with high accuracy. Can not realize substantial improvement in accuracy. 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 main body, and the operation is complicated and requires experience.

In the slide fastener manufacturing apparatus, the positioning method, shape, component configuration, size, weight, and assembling method differ depending on the fastener type. Therefore, in the present configuration, positioning of the continuous fastener chain 21 is performed using the sensor unit on the processing unit main body side, and processing devices (main parts of processing, molds, etc.) for various processing to the continuous fastener chain 21 are processed It is separated from the main part of the unit and unitized. Therefore, the unit of this configuration only needs to have a positioning mechanism for the processing unit main body, and the positioning adjustment for the individual portions of the continuous fastener chain 21 is not necessary.

<Mounting part processing part>
Next, the mounting portion processing unit 300 will be described.
FIG. 26 is a perspective view of the attachment processing portion 300, and FIG. 27 is an exploded perspective view of the attachment processing portion 300. As shown in FIG.
The mounting portion processing portion 300 has 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 main body 301.

The processing unit main body 301 includes a base plate 311, a support column 313 and a unit attachment unit 315 provided on the base plate 311, a delivery mechanism 305 of the continuous fastener chain 21, and a drive unit 317. The punching unit 303 is attached to the unit attachment portion 315 from the front side. The delivery mechanism 305 is fixed on the base plate 311 and delivers the continuous fastener chain 21 to the punching unit 303. Further, the drive unit 317 disposed on the upper part of the support column 313 of the processing unit main body 301 drives the punching unit 303.

A unit attachment portion 315 fixed on the processing portion main body 301 side and provided separately from the punching unit 303 is provided with a sensor portion described later which detects the presence / absence and position of the continuous fastener chain 21 to be fed out.

FIG. 28 is a side view of the punching unit 303 shown in FIG. 27 as viewed from the V3 direction.
The punching unit 303 has 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 formed of a rectangular plate in a plan view, and are spaced apart in the vertical direction by four columns 325. The bottom plate 321 has a width Wc and a thickness tc. Inside each column 325, a biasing member such as a spring is provided. Then, the top plate 323 is biased upward by being separated from the bottom plate 321 by the biasing member in the support column 325.

The processing mechanism portion 327 includes a support portion 331 provided on the top plate 323, a lower mold portion 333 provided on the bottom plate 321, and a tool portion 337. A guide member 345 is disposed between the support portion 331 and the lower mold portion 333. A guide pin 335 connecting the support portion 331 and the lower mold portion 333 is inserted into the guide member 345 and 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 of the tool portion 337 described later is inserted, and each tool is slidably guided in the vertical direction.

FIG. 29 is a schematic side view showing the main part of the attachment processing 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. 2C, and the windowing punch 343 is a tool for forming the window 35 of FIG. 2C.

The punching punch 341 and the windowing punch 343 are slidably supported by a guide member 345 disposed above the lower mold portion 333. Further, the lower die portion 333 is formed with a drilling die 347 into which the drilling punch 341 is inserted and a windowing die 349 into which the window opening punch 343 is inserted. Between the guide member 345 and the lower mold portion 333 is a transport path of the continuous fastener chain 21 which is fed out by the delivery mechanism portion 305 shown in FIG. Then, when the space portion reaches the lower side of the tool portion 337, the continuous fastener chain 21 to be conveyed is stopped from being transported, and the tool portion 337 performs a hole forming process and a window forming process. Thus, the hole 33 and the window 35 shown in FIG. 2C are formed.

As shown in FIG. 27, the unit attachment portion 315 has a removable platform 353 on the top of the pair of blocks 351. A pair of support grooves 355 opposed to each other is formed on the side of the mounting and demounting table 353. The pair of support grooves 355 are formed along the mounting direction (Y direction) of the drilling unit 303 with respect to the processing portion main body 301.

FIG. 30 is a cross-sectional view schematically showing the mounting state of the bottom plate 321 of the perforation unit 303 to the unit attachment portion 315. As shown in FIG.
The distance Wd between the bottoms 357 of 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 td which is the groove width 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 the end surface of the block 351 on the back side in the Y direction.

When the drilling unit 303 is attached to the processing unit main body 301, both side edges of the bottom plate 321 of the drilling unit 303 are inserted into the support table 355 of the unit mounting portion 315 from the front side of the processing unit main body 301. Then, the punching unit 303 is pushed until the bottom plate 321 abuts on the side surface of the stopper 361. At this time, when the bottom plate 321 engages with the support groove 355, the punching unit 303 is positioned with respect to the conveying direction (X direction) of the continuous fastener chain 21 and the vertical direction (Z direction). Further, the punching unit 303 is positioned in the unit mounting direction (Y direction) by the bottom plate 321 contacting the outer peripheral portion of the stopper 361 (see FIG. 26).

Thus, the unit mounting portion 315 (processing portion side positioning portion) of the processing portion main body 301 is in contact with the bottom portion 357 of the support groove 355, the inner surface of the support groove 355 including the top surface of the mounting / demounting table 353, The contact surface supports the bottom plate 321. Thus, the unit attachment portion 315 and the bottom plate 321 function as positioning portions that restrict and position the movement of the punching unit 303.

When the drilling unit 303 is attached to the unit attachment portion 315, as shown in FIG. 26, the fixing member 365 is fixed to the one block 351 serving as the mounting / dismounting base 353 by the fixing bolt 367. As a result, the bottom plate 321 of the punching unit 303 is locked to the fixing member 365, and the drilling unit 303 is maintained in the state of being attached to the unit attachment portion 315.

In this attachment portion processing portion 300, as shown in FIG. 29, the continuous fastener chain 21 which is fed out by the delivery mechanism portion 305 shown in FIG. 26 is disposed between the guide member 345 and the lower mold portion 333 of the processing mechanism portion 327. Be done. And the site | part to which the reinforcement film 31 in the space part 29 of the continuous fastener chain 21 shown to FIG. 2 (B) was welded is arrange | positioned directly under the processing mechanism part 327.

In this state, when the drive unit 317 shown in FIG. 26 of the processing unit main body 301 is driven, in the perforation unit 303, the support column 325 contracts as the drive unit 317 presses the top plate 323, and the top plate 323 descends. With the lowering of the top plate 323, the punching punch 341 and the window opening punch 343 shown in FIG. 29 are lowered. Then, the punching punch 341 and the windowing punch 343 are inserted into the punching die 347 and the windowing die 349 of the lower mold portion 333 through the continuous fastener chain 21.

Thus, the mounting portion 37 having the hole 33 and the window 35 shown in FIG. 2C is processed in the space 29 where the reinforcing film 31 of the continuous fastener chain 21 is welded.

When manufacturing different types of slide fasteners 45 in the attachment portion processing unit 300, the punching unit 303 attached to the processing unit main body 301 is replaced with the punching unit 303 corresponding to the slide fastener 45 to be manufactured next.

When the drilling unit 303 is removed from the processing unit main body 301, the fixing bolt 367 is loosened to remove the fixing member 365, and the drilling unit 303 is pulled forward so as to pull out the bottom plate 321 from the support groove 355. Thereby, the punching unit 303 is easily removed from the processing unit main body 101.

Then, when assembling the punching unit 303 corresponding to the next production to the processing unit main body 301, as described above, the conveying direction (X direction) of the continuous fastener chain 21 and the unit mounting direction (Y direction) Positioning can be accurately performed in the vertical direction (Z direction), and the time for setup change can be significantly reduced. In addition, since the operator need not be trained for setup change, it is possible to quickly respond to the production of a wide variety of product types, and to construct a production line with low cost and improved production efficiency.

Next, the sensor unit provided in the processing unit main body 301 will be described.
FIG. 31 is an enlarged perspective view of the delivery mechanism 305 of the processing unit main body 301. As shown in FIG.
The transport path of the continuous fastener chain 21 is formed between the lower rail 371 supporting the lower side of the continuous fastener chain and the upper rail 373 disposed above the lower rail 371 with the continuous fastener chain interposed therebetween.

The delivery mechanism unit 305 is provided with a space detection unit 375 (details shown in FIG. 32) below the conveyance path of the continuous fastener chain 21 and detects the distance from the end of the space above the conveyance path. Part 377 is provided.

The distance detection unit 377 has the same configuration as the distance detection unit 288 (see FIG. 23) of the delivery mechanism unit 207 described above. That is, the distance detection unit 377 includes the fixed plate 379, the slide rail 381, the slide member 383, the detection piece 385, the light sensor 387, and the chain locking member 389. The fixing plate 379 is provided in a state of being fixed to the processing portion main body 301 (see FIG. 27), and the slide rail 381 is fixed to the fixing plate 379. The slide member 383 is movably supported by the slide rail 381 and is tensioned along the slide rail 381 in the X direction in the drawing in the X direction by a spring (not shown). The detection piece 385 is fixed above the slide member 383, and the chain locking member 389 is fixed below the slide member 383. The detection piece 385 is made of a plate provided on a part of the slide member 383. The chain locking member 389 has a locking portion 389a (see FIG. 32) protruding downward at the tip. The optical sensor 387 is disposed 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 operation explanatory view showing operations of the space detection unit 375 and the distance detection unit 377.
The space portion detection unit 375 below the transport path includes a swing lever 391 supported rotatably around a fulcrum 391 a, a rotation disk 393, a detection piece 395, and an optical sensor 397.

The operations of the space detection unit 375 and the distance detection unit 377 are the same as in the case of the configuration shown in FIGS. 25 (A) and 25 (B) described above. That is, the swing of the swing lever 391 due to the displacement of the rotating disk 393 is detected by the light sensor 397. Further, the downstream end in the transport direction of the space portion 29 of the continuous fastener chain 21 is locked to the locking portion 389a of the chain locking member 389, and moves along the transport direction as shown by the arrow Pb in the drawing. The movement of the chain locking member 389 is detected by the light sensor 387.

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

light sensors

387 and 397 which are the above-mentioned position detection sensors, and the reinforcing film shown in FIG. 31 is placed. When the tool portion 337 is pressed downward, the hole 33 and the window 35 are formed at the formation position of the drilled hole of the continuous fastener chain 21.

The space detection unit 375 and the distance detection unit 377, which are sensor units, are both fixed to the processing unit main body 301 side, and are configured separately from the punching unit 303. Therefore, even if various drilling units 303 are supported by the processing unit main body 301 at the time of setup change, the space detection unit 375 and the distance detection unit 377 are always positioned accurately with respect to the conveyance path of the continuous fastener chain 21. Is maintained.

According to the slide fastener manufacturing apparatus described above, the

units

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

processing unit bodies

101, 201, and 301 in the

processing units

100, 200, and 300, respectively. Therefore, the work of setup change at the time of manufacturing different slide fasteners only needs to replace the

units

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

units

103, 105, 203, 205, and 303 on the

processing unit bodies

101, 201, and 301, the

units

103, 105, 203, 205, and 303 can be accurately positioned on the

processing unit bodies

101, 201, and 301. Be done. As a result, it is possible to eliminate the need for fine positioning work and the like, and it is possible to change the setup without requiring skill. Therefore, compared with the case of using a dedicated manufacturing apparatus provided with a dedicated mechanism for each slide fastener to be manufactured, the number of manufacturing apparatuses can be reduced, and the operation rate of one manufacturing apparatus can be improved. Running cost can be reduced.

In addition, by preparing a plurality of units used to manufacture the same type slide fastener, even if a failure occurs in a unit in use, it is only necessary to replace the failed unit, and the production line can be restarted quickly. Can.

Moreover, according to the slide fastener manufacturing apparatus of this configuration, each

processing part

100, 200, 300 such as the space part processing part 100, the reinforcement film welding processing part 200, and the mounting part processing part 300 has the presence or absence of the continuous fastener chain 21. A sensor unit for detecting the position or position is provided on the processing unit

main body

101, 201, 301 side. At the same time, drive

units

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

main body

101, 201, and 301 side. The sensor unit and the drive unit do not exist on the side unitized as the upper unit 103, the lower unit 105, the upper unit 203, the lower unit 205, the punching unit 303, and the like.

As described above, by providing the sensor unit and the drive unit on the processing unit main body side of each

processing unit

100, 200, and 300, the production facility can be realized at low cost even when using a large number of units. That is, each unit can be operated using the same sensor unit and the same drive unit, and the design and management of the unit become easy, and the maintainability is also improved. Furthermore, since the signal line and various piping etc. are not connected to the unit side made exchangeable, the handling property of the unit itself improves, and it can improve workability and storage property. In addition, since the lubricating oil, the cleaning agent and the like necessary for rust prevention, antifouling and foreign matter removal can be used on the unit side without being aware of the sensor unit and the drive unit, maintenance and management of the unit becomes easy.

The space processing unit 100, the reinforcement film welding processing unit 200, and the mounting unit processing unit 300, which constitute the pretreatment device 3 of each configuration, are an upper unit 103, a lower unit 105, an upper unit 203, a lower unit 205, And each

unit

103, 105, 203, 205, 303 of the perforation | punching unit 303 grade | etc., Is fastened by the fixing bolt 143,193,243,271,367. These fixing

bolts

143, 193, 243, 271, 367 are all fastening members standardized to the same standard size, that is, for example, the nominal dimensions of a screw such as "M8", and fastening and unfastening can be performed by a common tool. It is made possible. As a fastening member, a hexagon socket head cap bolt and a bolt nut are mentioned, for example. The common tool means, for example, in the case of a hexagonal wrench or a spanner, one having the same two-sided width dimension.

The fixing

bolts

143, 193, 243, 271, and 367 for fastening these units are of the same color (for example, red, yellow, etc. of primary colors such as good visibility) in order to distinguish them from bolts and screws that fix other parts. It is preferable to use color, gold, fluorescent color, etc.).

Since the fixing

bolts

143, 193, 243, 271, and 367 can be fastened with a common tool, the operator does not have to change tools for each part of the unit at the time of setup replacement, and work efficiency can be improved. . In addition, by unifying the same color, it is possible to easily visually recognize the position of the bolt to be attached and removed by the operator at the time of setup change. As a result, there is no occurrence of erroneous work such as unintended removal of bolts or screws, forgetting to remove, forgetting to attach, etc., and necessary work can be completed quickly and reliably.

In addition, each

unit

103, 105, 203, 205, 303 gives an identifier of the same numeral, the same symbol, or the same color for each type such as the size or the specification of the slide fastener 45 to be manufactured, and stores, manages, It is preferable to identify. For example, it is preferable to attach a sticker with a corresponding symbol and a sticker of a corresponding color to the manufacturing apparatus body and each unit. This makes it difficult for an operator to make an error, and the confirmation operation can be easily performed. In addition, it may replace with a seal and may apply painting etc. of a specific color.

Thus, the present invention is not limited to the above-described embodiment, and those skilled in the art can change or apply the components of the embodiment in combination with one another, based on the description of the specification, and based on known techniques. It is also the intention of the present invention to be included in the scope for which protection is sought.
For example, each positioning unit described above is not limited to the configuration of the illustrated example, but in the direction perpendicular to the conveying direction of the continuous fastener chain and the direction along the conveying direction with respect to the processing unit main body, As long as positioning is possible, any configuration may be used.

Moreover, although this continuous fastener chain illustrated the resin fastener provided with the resin-made element, the metal fastener provided with the metal-made element may be sufficient. In that case, unlike the resin fastener, the space portion 29 (see FIG. 2) is provided in advance and the metal element is attached to the tape, so the space portion processing portion 100 becomes unnecessary.

Furthermore, the sensor element used for the sensor unit is not limited to the measuring roller and the light sensor described above, but may be sensors of other types. For example, various sensors such as a magnetic sensor, a pressure sensor, and a photoelectric sensor, or a microswitch can be used.

In addition, a common plug may be provided for each type of each unit, and the processing unit main body may be provided with a connector that engages only the plug of the unit to be mounted. In such a case, when the operator erroneously mounts the unit, the plug of the unit does not engage with the connector of the processing unit main body, so that the operator can be made aware that the unit is erroneously mounted.
