As a heating unit that bonds the reinforcing tape to the fastener chain, there is an ultrasonic bonding device or a heater. The ultrasonic bonding device heats the reinforcing belt in a short time. However, the fused reinforcing tape is difficult to penetrate into the structure of the zipper tape. As a result, the adhesive strength between the fastener chain and the reinforcing tape tends to be low. In particular, in a fastener chain in which a water repellent treatment layer or a water stop layer is formed on the surface of the fastener tape, the tendency is strong. Therefore, the reinforcing tape needs to be heated for a relatively long period of time. Further, if the reinforcing tape is heated for a long period of time, there is a problem that air bubbles are generated between the reinforcing tape and the fastener chain, thereby causing white turbidity.

In the reinforced tape sticking method described in Patent Document 1, the zipper chain is pinched by a heated stencil, heated in a predetermined time, and the reinforced tape is adhered to the zipper chain. Therefore, the reinforcing tape and the fastener chain have high adhesive strength, but are white turbid, and the appearance is poor in appearance, and the commercial value is lowered.

Figure 5 is a plan view of a fastener chain to which a reinforcing film is adhered.

Hereinafter, an embodiment of the reinforced film adhesive device of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the reinforcing film adhering device 10 is an adhesive device for adhering the reinforcing film 16 to the space portion 12 to which the fastener chain 11 of the opening and closing device (not shown) is attached. The reinforced film bonding apparatus 10 includes a zipper chain conveying unit 20, a reinforced film tape supply unit 30, a cutting mechanism 40, a reinforced film conveying unit 50, a heat bonding device 70 as a reinforcing film bonding unit, and a film cooling device. 80.

As shown in FIG. 5, the fastener chain 11 has a chain row 15 along the opposing belt side edge portions 13a of the pair of long fastener tapes 13. The element row 15 has a plurality of elements 14 adjacent in the longitudinal direction of the fastener chain 11. The sprocket 14 is made of resin and is injection molded on the belt side edge portion 13a. Further, the fastener chain 11 is formed by removing a predetermined amount from the element row 15 at a predetermined interval in the longitudinal direction of the fastener chain 11. The space portion 12 formed by the sprocket 14 is formed.

As shown in FIG. 2, the fastener chain conveying unit 20 is disposed on the downstream side in the conveying direction of the fastener chain 11 than the position where the thermal adhesive device 70 and the diaphragm cooling device 80 are disposed. The fastener chain conveying unit 20 conveys the fastener chain 11 along the conveyance path. Further, the fastener chain transport unit 20 includes a drive roller 21 and a driven roller 22 that are disposed to face each other across a transport path of the fastener chain 11 . The drive roller 21 is connected to a motor (not shown). The driven roller 22 presses the fastener chain 11 toward the driving roller 21. That is, the fastener chain 11 is sandwiched by the driving roller 21 and the driven roller 22. When the drive roller 21 is rotationally driven, the driven roller 22 is rotated in synchronization, and the fastener chain 11 is conveyed toward the downstream side in the conveyance direction.

The sensing unit 24 is disposed on the upstream side in the conveying direction of the fastener chain 11 than the installation position of the thermal bonding device 70. The sensing unit 24 includes a sensing roller 25 disposed above the element row 15 and a swing lever 26 that swings the sensing roller 25 in the vertical direction. The sensing roller 25 rotates while being in contact with the element row 15 of the transported fastener chain 11. The sensing roller 25 intrudes into the space portion 12 when the space portion 12 of the transported fastener chain 11 reaches the position below the sensing roller 25. At this time, the sensing roller 25 enters into the gap S formed between the belt side edge portions 13a of the pair of fastener tapes. Thereby, the sensing roller 25 moves downward, and the swing lever 26 swings downward, and the sensing unit 24 detects the space portion 12.

When the space unit 12 is detected by the sensing unit 24, the fastener chain transport unit 20 further transports the fastener chain 11 at a predetermined distance. Further, the zipper chain transport unit 20 is moved to the position of the thermal adhesive device 70 when the space portion 12 is moved in a plan view. When the position is stopped, the conveyance of the zipper chain 11 is stopped. Further, the fastener chain transport unit 20 restarts the transport of the fastener chain 11 after the thermal adhesive device 70, which will be described later, finishes the adhesion of the reinforcing film 16. Further, when the zipper chain conveying unit 20 moves in the space portion 12, in other words, the adhered reinforcing film sheet 16 is moved to a position overlapping the position of the film cooling device 80 in a plan view, the conveyance of the fastener chain 11 is stopped. Further, the zipper chain transport unit 20 restarts the transport of the fastener chain 11 after the diaphragm cooling device 80 cools the reinforced diaphragm 16. The zipper chain transport unit 20 repeats the above operation to transport the zipper chain 11.

As shown in FIGS. 2 and 3, the reinforcing film tape supply unit 30 is disposed on the side of the transport path of the fastener chain 11. The reinforcing film tape supply unit 30 has a reinforcing film tape roll (not shown) around which the reinforcing film tape 17 is wound. Further, the reinforcing film tape supply unit 30 accommodates the reinforcing film tape 17 so that the reinforcing film tape 17 extends in a direction orthogonal to the conveying direction of the fastener chain 11.

The reinforcing film tape supply unit 30 includes a guide head 32 that is movable in a direction orthogonal to the conveying direction of the fastener chain 11 at a distal end portion facing the fastener chain 11 . That is, the guide head 32 can be moved to a position close to the fastener chain 11 and a position spaced apart from the fastener chain 11. The guide head 32 is biased in a direction approaching the fastener chain 11 by a spring (not shown). The guide head 32 has a pair of slits 31 through which the reinforcing film tape 17 is inserted. Each of the slits 31 is arranged in parallel with each other at intervals in the vertical direction. The reinforcing film tape 17 is taken out from each slit 31 by a holder 51 which will be described later. At this time, each slit 31 guides the movement of the reinforcing film tape 17 so that the reinforcing film tape 17 is drawn toward the upper surface and the lower surface of the fastener chain 11.

Further, the reinforcing film tape 17 is a film tape formed of a synthetic resin having a relatively low melting point such as a nylon-based or polyester-based material.

As shown in FIG. 3, the cutting mechanism 40 includes a cutter 41 disposed below the guide head 32 and a driving device 42 for moving the cutter 41 in the vertical direction. That is, the cutter 41 is movable to an upper position close to the guide head 32 and a lower position spaced apart from the guide head 32. At this time, the cutter 41 moves along the front end face 32a of the guide head 32. The cutting mechanism 40 cuts the pair of reinforcing film tapes 17 taken out from the pair of slits 31 by moving the cutter 41 up and down, thereby forming a pair of reinforcing film sheets 16. The length of the reinforcing film 16 (the length in the direction orthogonal to the conveying direction of the fastener chain 11) is set to be slightly shorter than the width of the fastener chain 11.

The reinforcing film conveying unit 50 includes a holder 51 that grips a pair of reinforcing film tapes 17 or a pair of reinforcing films 16, and a conveying direction of the holder 51 along the reinforcing film tape 17 and conveyance of the fastener chain 11 A directionally moving gripper drive unit 52.

The holder 51 includes a fixing claw piece 53 having a groove 53a that can accommodate the fastener chain 11 at the distal end portion, and a pair of movable claw pieces 54a and a movable claw piece 54b that are disposed to face up and down with the fixing claw piece 53. The movable claw piece 54a and the movable claw piece 54b are elongated in the drawing direction of the reinforcing film tape 17, and have a front end facing the guiding head 32, a base end opposite to the front end, and a middle between the front end and the base end. unit. The movable claw piece 54a and the movable claw piece 54b are rotatably supported by a holder 56 to be described later around the shaft 55 provided at the intermediate portion. Further, the movable claw piece 54a and the movable claw piece 54b are biased by a spring (not shown) such that the distal end thereof is spaced apart from the distal end of the fixed claw piece 53. That is, the movable claw piece 54a and the movable claw piece 54b are movable to the fixed claw piece 53. The position where the front end is close and the position spaced apart from the front end of the fixed claw piece 53.

A pair of opening portions 57a and openings 57b that are openable and closable are formed between the distal end of the fixed claw piece 53 and the distal end of the movable claw piece 54a and the movable claw piece 54b. Each of the opening 57a and the opening 57b is located at a position facing the pair of slits 31 of the guide head 32. When the front end of the pair of reinforcing film tapes 17 protrudes from the slit 31, they are inserted into the corresponding opening portions 57a and 57b, respectively, and are gripped.

Further, a gap 58 is formed between the pair of movable claw pieces 54a and the base end of the movable claw piece 54b. The cam portion 59a formed at the front end of the piston 59 is disposed in the gap 58 and disposed. The piston 59 is biased so as to be spaced apart from the gap 58 by a spring (not shown). When the cam portion 59a of the piston 59 is separated from the gap 58 by the spring force of the spring, the distal ends of the movable claw piece 54a and the movable claw piece 54b are spaced apart from the distal end of the fixed claw piece 53. Thereby, between the distal end of the movable claw piece 54a and the movable claw piece 54b and the distal end of the fixed claw piece 53, the opening 57a and the opening 57b are opened.

Further, the holder 51 inserts the pair of reinforcing film tapes 17 into the opening 57a and the opening 57b, and then the cam portion 59a of the piston 59 enters the gap 58. Thereby, the pair of movable claw pieces 54a and the movable claw pieces 54b swing around the shaft 55, and the opening 57a and the opening 57b are closed. At this time, the front end of the fixed claw piece 53 and the movable claw piece 54a and the front end of the movable claw piece 54b hold the pair of reinforcing film tapes 17.

The gripper driving unit 52 moves the gripper 51 along the drawing direction of the reinforcing film tape 17 and the conveying direction of the fastener chain 11. The holder driving unit 52 is disposed on the opposite side of the reinforcing film tape supply unit 30 with respect to the fastener chain 11. The gripper drive unit 52 includes: a servo motor 68 coupled to the holder 56, mounted with a servo The moving table 62 of the motor 68 and the cylinder device 61 connected to the moving table 62. The servo motor 68 moves the gripper 51 in the drawing direction of the reinforcing film tape 17. The cylinder device 61 moves the moving table 62 in the conveying direction of the fastener chain 11, thereby moving the gripper 51 in the conveying direction of the fastener chain 11.

The moving table 62 includes a first wall 63 and a second wall 64 that are spaced apart from each other in a direction orthogonal to the conveying direction of the fastener chain 11. Between the first wall 63 and the second wall 64, the pair of guide bars 65 are spaced apart from each other in the conveying direction of the fastener chain 11, and are arranged in parallel with each other. Further, each of the guide bars 65 extends in a direction orthogonal to the conveying direction of the fastener chain 11 (the direction in which the reinforcing film tape 17 is taken out). A holder 56 for holding the holder 51 is slidably attached to the pair of guide rods 65.

Further, a ball screw mechanism is disposed between the first wall 63 and the second wall 64 of the moving table 62. The ball screw mechanism includes a screw shaft 66 that extends in a direction orthogonal to the conveying direction of the fastener chain 11, and a ball nut 67 that is screwed to the screw shaft 66. The holder 56 is coupled to the servo motor 68 via a ball nut 67. The screw shaft 66 is rotationally driven by a servo motor 68 fixed to the second wall 64. At this time, the ball nut 67 moves along the screw shaft 66 in a direction orthogonal to the conveying direction of the fastener chain 11. Thereby, the holder 56 is guided by the pair of guide bars 65 together with the gripper 51, and moves in a direction orthogonal to the conveyance direction of the fastener chain 11.

Thus, since the gripper 51 is driven by the servo motor 68, it can be stopped at any position along the direction orthogonal to the conveyance direction of the fastener chain 11. Specifically, the holder 51 can be stopped at four places, that is, the holder 51 holds the holding position P1 of the front end of the pair of reinforcing film tapes 17 guided by the slit 31, and a pair The cutting position P2 at which the film tape 17 is cut is reinforced, the standby position P3 in which the pair of reinforcing films 16 are held and held, and the retracted position P4 retracted from the thermal bonding device 70.

The cylinder device 61 includes a piston rod 69 that is coupled to the moving table 62 at one end. The cylinder device 61 allows the piston rod 69 to expand and contract in the conveying direction of the fastener chain 11. Thereby, the gripper 51 moves in the conveying direction of the fastener chain 11 by the expansion and contraction of the piston rod 69 of the cylinder device 61. That is, the gripper 51 reciprocates between the standby position P3 and the adhesive position P5 which is located on the upstream side in the transport direction of the fastener chain 11 from the standby position P3. The adhesive position P5 is a position at which the reinforcing film 16 is adhered to the space portion 12 of the fastener chain 11.

In the thermal adhesive device 70, the pair of reinforcing film tapes 17 and the fastener chain 11 which are taken out from the reinforcing film tape supply unit 30 are disposed at positions which are intersected with each other in a plan view (standby position P3), and the fastener chain 11 The position where the conveyance direction is deviated (in the present embodiment, the adhesion position P5 on the upstream side with respect to the standby position P3). The thermal bonding apparatus 70 includes a template that is in contact with the reinforcing membrane 16 to heat the reinforcing membrane 16. The template includes a first template 71 and a second template 72 that are disposed to face each other across a transport path of the fastener chain 11. The first template 71 is disposed above the fastener chain 11 . The second template 72 is disposed below the fastener chain 11 . The heat bonding device 70 includes a heater 73 in order to heat the reinforcing film 16. Specifically, the first template 71 and the second template 72 incorporate a heater 73. The first template 71 and the second template 72 are vertically movable by a driving device (not shown). That is, the first template 71 and the second template 72 can be moved to a position spaced apart from the reinforcing film 16 adhered to the fastener chain 11 and a position close to the reinforcing film 16. The thermal bonding device 70 utilizes the first template 71 and the second The template 72 holds the fastener chain 11 and a pair of reinforcing film sheets 16 which are disposed to face the upper and lower surfaces of the fastener chain 11 (space portion 12) and are heated. Thereby, the reinforcing film 16 is melted and adhered to the upper and lower surfaces of the fastener chain 11.

The diaphragm cooling device 80 is disposed closer to the downstream side in the transport direction of the fastener chain 11 than the thermal adhesive device 70. The diaphragm cooling device 80 includes a cooling member that contacts the reinforcing diaphragm 16 adhered to the fastener chain 11 to cool the reinforcing membrane 16. The cooling member includes a first cooling member 81 and a second cooling member 82 that are disposed to face each other across a conveying path of the fastener chain 11 . The first cooling member 81 is disposed above the fastener chain 11 . The second cooling member 82 is disposed below the fastener chain 11 . The first cooling member 81 and the second cooling member 82 are vertically movable by a driving device (not shown). That is, the first cooling member 81 and the second cooling member 82 are movable to a position spaced apart from the reinforcing film 16 adhered to the fastener chain 11 and a position close to the reinforcing film 16.

The first cooling member 81 and the second cooling member 82 are formed of a metal material having a heat capacity much larger than that of the reinforcing diaphragm 16. Further, the reinforcing film sheet 16 is sandwiched together with the fastener chain 11 by the first cooling member 81 and the second cooling member 82, whereby the heat of the reinforcing film sheet 16 is absorbed and cooled. That is, the heat of the reinforcing film 16 is transmitted from the contact portion of the reinforcing film 16 to the first cooling member 81 and the second cooling member 82 to the first cooling member 81 and the second cooling member 82. Thereby, the reinforcing diaphragm 16 is rapidly cooled. Further, the material of the first cooling member 81 and the second cooling member 82 is not limited to a metal material, and may be any material having a large heat capacity and a large heat transfer rate. Moreover, the first cooling member 81 and the second cooling member 82 It can also be actively cooled by the circulating supply of coolant.

Next, a method of adhering the reinforcing film 16 to the fastener chain 11 by the reinforcing film adhering device 10 will be described. Further, the gripper 51 holds the pair of reinforcing diaphragms 16 and stands by at the standby position P3, and the description begins. That is, the gripper 51 at the standby position P3 causes the cam portion 59a of the piston 59 to enter the gap 58 between the pair of movable claw pieces 54a and the base end of the movable claw piece 54b, and closes the opening portion 57a and the opening portion 57b. . Thereby, the front end of the movable claw piece 54a and the movable claw piece 54b and the front end of the fixed claw piece 53 hold the pair of reinforcing film sheets 16.

First, the fastener chain transport unit 20 rotates the drive roller 21 to transport the fastener chain 11. At this time, in the sensing unit 24, the sensing roller 25 rotates while being in contact with the element row 15 of the fastener chain 11. Soon, when the sensing roller 25 reaches the position of the sensing roller 25 at the space portion 12 of the fastener chain 11, the sensing roller 25 is released from contact with the element row 15 and enters the space portion 12. At this time, the sensing roller 25 enters into the gap S formed between the belt side edge portions 13a of the pair of fastener tapes. Thereby, in the sensing unit 24, the sensing roller 25 moves downward, and the swing lever 26 swings, thereby detecting the space portion 12.

When the space portion 12 is detected by the sensing unit 24, the fastener chain transport unit 20 further transports the fastener chain 11 to stop the space portion 12 between the first template 71 and the second template 72 of the thermal adhesive device 70.

The length measuring unit measures the transport distance of the fastener chain 11 to stop the transport of the fastener chain 11. As the length measuring unit, an encoder attached to the driving roller 21 can be employed. After the encoder detects the space portion 12 by the sensing unit 24, The rotation angle of the driving roller 21 measures the conveying distance of the fastener chain 11. Thus, when the transport distance of the fastener chain 11 reaches a predetermined distance (the distance between the sensing unit 24 and the thermal adhesive device 70), the fastener chain transport unit 20 stops the rotation of the drive roller 21 and transports the fastener chain 11 stop.

Then, the gripper drive unit 52 operates the cylinder device 61 to contract the piston rod 69. Thereby, the gripper 51 that stands by at the standby position P3 moves together with the moving table 62 toward the upstream side in the conveying direction of the fastener chain 11. That is, the gripper 51 is moved to the adhesive position P5. Further, the pair of reinforcing films 16 are moved between the first die plate 71 and the second die plate 72 while being held by the gripper 51 while being opposed to the upper and lower surfaces of the fastener chain 11, respectively.

Further, the gripper 51 can be moved from the standby position P3 to the adhesive position P5 simultaneously with the conveyance of the fastener chain 11.

Then, the temporary pressing mechanism (not shown) provided in the first template 71 and the second template 72 temporarily presses the pair of reinforcing films 16 so that the overlapping positions of the pair of reinforcing films 16 and the fastener chain 11 are not offset. . Then, the holder 51 opens the opening 57a and the opening 57b, and releases the holding of the pair of reinforcing films 16.

Then, the gripper drive unit 52 drives the servo motor 68 to rotate the screw shaft 66, thereby moving the gripper 51 from the adhesive position P5 to the retracted position P4. Thereby, the holder 51 avoids contact with the first template 71 and the second template 72 when the first template 71 and the second template 72 move toward the fastener chain 16 in order to adhere to the fastener strip 16 (moving up and down).

Then, the first template 71 is lowered, and the second template 72 is raised. thus, The first template 71 and the second template 72 sandwich a pair of reinforcing films 16 disposed to face each other on the upper and lower surfaces of the fastener chain 11 together with the fastener chain 11. Then, the first template 71 and the second template 72 heat the pair of reinforcing films 16 to adhere the pair of reinforcing films 16 to the upper and lower surfaces of the fastener chain 11.

The pair of reinforcing diaphragms 16 are heated by the thermal bonding device 70 for a sufficient time for adhering to the fastener chain 11. For example, in the short-time heating using ultrasonic waves, when the reinforcing film sheet 16 is adhered to the fastener tape 13 having the water-stopping layer or the water-repellent treatment layer formed on the surface, sufficient adhesion strength may not be obtained. Since the heat-adhesive device 70 of the present embodiment sufficiently heats the reinforcing film sheet 16, the adhesion strength between the reinforcing film sheet 16 and the fastener chain 11 is improved.

The holder driving unit 52 operates the cylinder device 61 to extend the piston rod 69 while the heat-adhesive device 70 adheres the reinforcing film 16 to the fastener chain 11. Thereby, the gripper 51 located at the retracted position P4 moves toward the downstream side in the conveyance direction of the fastener chain 11 together with the mobile station 62. That is, the gripper 51 is moved to the standby position P3.

Further, the gripper drive unit 52 rotates the screw shaft 66 by the servo motor 68, thereby moving the holder 56 fixed to the ball nut 67. Thereby, the gripper 51 is moved to the holding position P1 at which the reinforcing film tape 17 can be gripped.

At this time, the gripper 51 moves in a direction orthogonal to the transport direction of the fastener chain 11 across the transport path of the fastener chain 11 . The zipper chain 11 is housed in the groove 53a of the fixed claw piece 53, and thus does not become an obstacle to the movement of the holder 51.

When the gripper 51 moves from the standby position P3 to the grip position P1, it abuts The guide head 32 of the film supply unit 30 is reinforced. At this time, the gripper 51 moves the guide head 32 in a direction opposite to the direction in which the reinforcing film tape 17 is pulled, against the elastic force of the spring. Thereby, the front end of the pair of reinforcing film tapes 17 protrudes from the pair of slits 31 by the moving distance of the guiding head 32. Further, the front end of the pair of reinforcing film tapes 17 is inserted into the opening 57a and the opening 57b of the holder 51.

Here, the cam portion 59a of the piston 59 enters the gap 58 between the pair of movable claw pieces 54a and the base end of the movable claw piece 54b. Thereby, the movable claw piece 54a and the movable claw piece 54b swing around the shaft 55, and the opening part 57a and the opening part 57b are closed. Thereby, the fixed claw piece 53 and the pair of movable claw pieces 54a and the movable claw pieces 54b hold the front ends of the pair of reinforcing film tapes 17.

Then, the gripper drive unit 52 drives the servo motor 68 to move the gripper 51 to the cut position P2 and stop. Thereby, the pair of reinforcing film tapes 17 held by the gripper 51 are taken out from the slit 31 with a length slightly smaller than the width of the fastener chain 11. Further, the guide head 32 is returned to the original position by the elastic force of the spring simultaneously with the movement of the gripper 51.

Here, the cutting mechanism 40 raises the cutter 41 by the driving device 42. Thereby, the cutting mechanism 40 cuts the pair of reinforcing film tapes 17 along the front end surface 32a of the guide head 32, thereby forming a pair of reinforcing film sheets 16.

Further, the gripper drive unit 52 further drives the servo motor 68 to move the gripper 51 holding the pair of reinforcing diaphragms 16 to the standby position P3. The gripper drive unit 52 causes the gripper 51 to stand by at the standby position P3 until the adhesion of the heat-adhesive device 70 to the reinforcing diaphragm 16 is completed.

In this manner, the reinforcing film adhering device 10 performs the following steps in parallel and simultaneously, so that the cycle time can be greatly shortened, and the respective steps are the step of adhering the reinforcing film 16 by the thermal bonding device 70, and the holder 51 The movement from the retracted position P4 to the holding position P1 causes the holding of the pair of reinforcing film tapes 17, the cutting at the cutting position P2, and the standby at the standby position P3.

Further, when the adhesion of the reinforcing film 16 to the fastener chain 11 is completed, the first die plate 71 and the second die plate 72 are vertically spaced apart from the fastener chain 11. Further, as shown in FIG. 4, the fastener chain transport unit 20 operates again to transport the fastener chain 11. Further, when the reinforcing film 16 adhered to the fastener chain 11 reaches a position overlapping the position of the film cooling device 80 in a plan view, the fastener chain conveying unit 20 stops the conveyance of the fastener chain 11.

When the fastener chain transport unit 20 transports the fastener chain 11 from the lower position of the thermal adhesive device 70 to the lower position of the diaphragm cooling device 80, the encoder (not shown) attached to the drive roller 21 carries the transport distance of the fastener chain 11 Measuring length. When the transport distance of the fastener chain 11 reaches a predetermined transport distance (the distance between the thermal adhesive device 70 and the diaphragm cooling device 80), the fastener chain transport unit 20 stops the rotation of the drive roller 21 and stops the transport of the fastener chain 11.

In the diaphragm cooling device 80, the first cooling member 81 is lowered, and the second cooling member 82 is raised. Thereby, the first cooling member 81 and the second cooling member 82 sandwich the pair of reinforcing diaphragms 16 adhered to the upper and lower surfaces of the fastener chain 11 together with the fastener chain 11. Moreover, the first cooling member 81 and the second cooling member 82 absorb the heat of the reinforcing film sheet 16, and cool the reinforcing film sheet 16.

Thus, after the pair of reinforcing films 16 are adhered to the fastener chain 11, they are not cooled naturally, but are immediately cooled by the film cooling device 80. Thereby, the bubbles generated by the heating are prevented from being clouded in the reinforcing film sheet 16.

Further, the gripper drive unit 52 operates the cylinder device 61 simultaneously with the cooling of the reinforcing diaphragm 16, and moves the gripper 51 that stands by at the standby position P3 to the adhesive position P5. The gripper 51 moves while holding the pair of reinforcing diaphragms 16. The pair of reinforcing films 16 are located between the first template 71 and the second template 72 in a state in which the upper and lower surfaces of the fastener chain 11 face each other.

Further, after the cooling of the reinforcing film 16 is completed, the fastener chain transport unit 20 operates again to transport the fastener chain 11. When the space portion 12 of the fastener chain 11 is transported between the first template 71 and the second template 72 of the thermal adhesive device 70, the fastener chain transport unit 20 stops the transport of the fastener chain 11. Further, the thermal bonding device 70 adheres the pair of reinforcing films 16 to the space portion 12 of the fastener chain 11. After the film bonding apparatus 10 is reinforced, the same operation is repeated, and the reinforcing film 16 is sequentially adhered to the space portion 12 of the fastener chain 11.

By the series of operations, the fastener chain 11 in which the reinforcing film 16 is adhered to the space portion 12 of the pair of fastener tapes 13 as shown in FIG. 5 is obtained. The reinforcing film 16 is heated and adhered for a relatively long period of time by the heat bonding device 70, and thus is firmly adhered to the fastener chain 11, and has high adhesive strength. Further, the heat-adhesive reinforcing film 16 is immediately cooled by the film cooling device 80, so that generation of white turbidity can be prevented.

As described above, the reinforced film adhesive device 10 of the present embodiment includes the zipper chain transport unit 20, the reinforced film tape supply unit 30, and the reinforced film tape 17 The cutting mechanism 40 includes a reinforcing film conveying unit 50 of the gripper 51 and the gripper driving unit 52, and a thermal adhesive device 70. The reinforced film adhering device 10 is disposed at a downstream side of the heat-adhesive device 70 in the transport direction, and is provided with a film cooling device 80 for cooling the pair of reinforcing film sheets 16 to be adhered, thereby securing the fastener chain 11 and the reinforcing film 16 The adhesion strength and the generation of white turbidity in the reinforcing film 16 can be prevented. Thereby, the reduction in the value of the commodity can be prevented.

Therefore, the reinforced film adhering device 10 of the present embodiment is formed with a water stop layer or a water repellent treatment layer on the surface, and is effective for the zipper tape 13 in which the reinforcing film sheet 16 is adhered to ultrasonic adhesion without obtaining sufficient adhesive strength.

Further, in the reinforced film adhesive device 10 of the present embodiment, the film cooling device 80 includes the first cooling member 81 and the second cooling member 82 which are disposed to face each other. Thereby, the first cooling member 81 and the second cooling member 82 sandwich the reinforcing film sheet 16 adhered to the fastener chain 11 together with the fastener chain 11 and effectively cool it, thereby preventing white turbidity from occurring in the reinforcing film sheet 16.

In addition, the present invention is not limited to the above-described embodiments, and modifications may be appropriately made without departing from the spirit and scope of the invention.

For example, the reinforcing film adhesive device 10 can also adhere the reinforcing film 16 to either one of the upper surface or the lower surface of the fastener chain 11. In this case, the reinforcing film tape supply unit 30 supplies the reinforcing film tape 17 so as to face either one of the upper surface or the lower surface of the fastener chain 11. Further, the template that is in contact with the reinforcing film 16 and the cooling member that is in contact with the reinforcing film 16 may be disposed only in one of the upper and lower sides of the transport path of the fastener chain 11.

Further, the thermal adhesive device 70 of the reinforced film adhesive device 10 can be disposed on the downstream side in the transport direction with respect to the position where the reinforcing film tape 17 taken out from the reinforced film tape supply unit 30 and the fastener chain 11 intersect at a position in plan view. Further, the thermal adhesive device 70 may be disposed at a position where the reinforcing film tape 17 taken out from the reinforcing film tape supply unit 30 and the fastener chain 11 intersect in a plan view. In this case, the cylinder device 61 that reciprocates the moving table 62 is not required.

Further, the sprocket 14 of the element row 15 may be a coil element or a metal element in which a monofilament is wound in a coil shape.
