As shown in fig. 3, 5, and 6, the film conveying device 40 includes grippers 41 that grip the left and right reinforcing film tapes Ft, and a gripper driving device 47 that moves the grippers 41 in the fastener chain conveying direction (front-rear direction).
The gripper 41 includes a film guide member 42 that guides the movement of the left and right reinforcing film tapes Ft, and a film gripping member 45 that can grip the reinforcing film tapes Ft on the film guide member 42.
The film guide member 42 includes a pair of left and right guide forks 43 for supporting the left and right reinforcing film tapes Ft from below, and is attached to a back plate 47c of a gripper driving device 47 described later. At the distal end portions of the left and right guide forks 43, elongated pin insertion holes 43a are formed for inserting clamp pins 62 described later. Further, film insertion holes 43b into which the left and right reinforcing film tapes Ft are inserted are formed in the base end portions of the left and right guide forks 43, respectively. The pin insertion hole 43a and the film insertion hole 43b are formed to penetrate the guide fork 43 in the vertical direction.
The film gripping member 45 includes a pair of left and right gripping forks 46 for gripping the left and right reinforcing film tapes Ft between the left and right guide forks 43, and is attached to an upper end portion of a slide rod 47e of a gripper driving device 47 to be described later. Protrusions 46a for pressing the left and right reinforcing film tapes Ft are formed at the distal ends of the left and right grip forks 46.
The reinforcing film tapes Ft are inserted into the left and right film insertion holes 43b of the film guide member 42 from below, and then inserted between the left and right guide forks 43 of the film guide member 42 and the left and right gripping forks 46 of the film gripping member 45. The tip of the reinforcing film tape Ft is inserted to the tip edge 51a of the insertion hole 51 of the cutting section 50 described later.
As shown in fig. 3 to 7, the gripper driving device 47 includes: a guide base (slide device) 47a fixed to the front plate 12a of the lower bracket 12; a slide rail (slide device) 47b attached to the guide base 47a so as to be movable in the chain conveying direction (front-rear direction); a back plate 47c fixed to the slide rail 47 b; a guide box 47d fixed to the back plate 47 c; a slide rod 47e attached to the guide box 47d so as to be movable in the vertical direction; a first cylinder device (first driving device) 48 that drives the slide rod 47e in the up-down direction; and a second cylinder device (second driving device) 49 that drives the back plate 47c in the front-rear direction (chain conveying direction). The back plate 47c is provided movably in the chain conveying direction by a guide base 47a and a slide rail 47b constituting a slide device.
The slide rod 47e extends through the guide box 47d in the vertical direction, and a rod 48a of the first cylinder device 48 is connected to a lower end portion of the slide rod 47 e. Therefore, by contracting the rod 48a of the first cylinder device 48, the slide rod 47e is driven in the up-down direction. The film holding member 45 is attached to the upper end of the slide rod 47 e.
The back plate 47c is connected to a rod 49a of the second cylinder device 49 via a connecting bolt 47 f. Therefore, by contracting the rod 49a of the second cylinder device 49, the back plate 47c is driven in the front-rear direction (chain conveying direction). In addition, a second cylinder device 49 is mounted on the rear surface of the front plate 12a of the lower bracket 12.
As shown in fig. 5, 6, and 8, the cutting section 50 is a block-shaped member, and has a pair of left and right fork insertion holes 51 through which the left and right guide forks 43 of the film guide member 42 are inserted. The fork insertion hole 51 is a rectangular through hole, and a transport path of the reinforcing film tape Ft is formed between the top surface of the fork insertion hole 51 and the upper surface of the guide fork 43. The distal edge 51a of the top surface of the insertion hole 51 constitutes a cutting blade for cutting the reinforcing film tape Ft between the cutting blade 72b of the anvil 72, which will be described later. Further, a pair of left and right fork accommodating grooves 52 are formed in the cutting portion 50, and the pair of left and right fork accommodating grooves 52 accommodate the left and right gripping forks 46 when the gripper 41 moves to the upstream side in the chain conveying direction, respectively. In addition, the fork insertion hole 51 and the fork accommodation groove 52 are connected in the vertical direction inside the cut portion 50, and are formed along the chain conveying direction inside the cut portion 50.
As shown in fig. 3, 6, and 8, the clamping device 60 includes: a housing 61 as a block-shaped member; a pair of left and right clamp pins 62 accommodated in the housing 61 and fixing the left and right reinforcing film tapes Ft; a pair of left and right coil springs 63 accommodated in the housing 61 and urging the left and right clamp pins 62 downward; a cam shaft 64 rotatably inserted into the housing 61 and driving the left and right clamp pins 62 upward; a connecting arm 65 having one end mounted to the cam shaft 64; and a cylinder device (cam shaft driving device) 66 that drives the other end of the connecting arm 65 in the vertical direction to rotate the cam shaft 64.
The housing 61 accommodates the left and right clamp pins 62 and the coil springs 63, and includes a pin accommodating hole 61a that accommodates the clamp pin 62 and a camshaft accommodating hole 61b that accommodates the camshaft 64 and rotatably supports the camshaft 64. In addition, the pin accommodating hole 61a is formed along the vertical direction of the housing 61. In addition, the camshaft receiving hole 61b is formed along the left-right direction of the housing 61. Further, when the clamp pin 62 moves upward, the upper end of the clamp pin 62 protrudes toward the fork insertion hole 51 of the cut-off portion 50.
The cam shaft 64 has a cam surface 64a formed in a middle portion in the longitudinal direction thereof substantially parallel to the chain conveying direction, and the lower ends of the left and right clamp pins 62 contact the cam surface 64 a. Therefore, when the cam shaft 64 rotates clockwise in fig. 6 (see fig. 10), the cam surface 64a pushes up the left and right clamp pins 62, and the reinforcing film tape Ft is sandwiched between the tip of the clamp pin 62 and the top surface of the fork insertion hole 51, whereby the position of the reinforcing film tape Ft is fixed.
The connecting arm 65 has a left end to which the cam shaft 64 is attached at one end thereof, and has a rod 66a of a cylinder device 66 attached at the other end thereof. Therefore, when the rod 66a of the cylinder device 66 advances and retreats, the connecting arm 65 rotates in the vertical direction, and the cam shaft 64 rotates.
As shown in fig. 1 and 2, the film adhesive portion 70 includes: an ultrasonic horn 71 disposed above the line L; an anvil 72 disposed below the conveying line L; a horn unit 80 for driving the ultrasonic horn 71 in the up-down direction; and an anvil unit 90 that drives the anvil 72 in the up-down direction. The ultrasonic horn 71 and the anvil 72 are disposed so as to face each other in the vertical direction via the line L.
The horn unit 80 includes: a pair of guide rods 81 which constitute a part of the upper holder 13 and are arranged in the vertical direction; a slide member 82 movably attached along the pair of guide rods 81; and a cylinder device 83 which is attached to the upper surface of the upper bracket 13 and drives the slide member 82 in the up-down direction. Further, the ultrasonic horn 71 is attached to the front surface of the slide member 82.
The slide member 82 is attached to the lower end of the rod 83a of the cylinder device 83. Therefore, by contracting the rod 83a of the cylinder device 83, the ultrasonic horn 71 is driven in the vertical direction together with the slide member 82.
The lower end surface of the ultrasonic horn 71 has a pressing surface 71a that presses the upper surfaces of the left and right tapes T of the fastener chain C against the anvil 72.
As shown in fig. 3, 5, and 6, the anvil unit 90 is a block-shaped member, and includes: a case 91 having an anvil guide hole 91a for accommodating the anvil 72 so as to be movable in the vertical direction; and a cylinder device 92 that drives the anvil 72 in the up-down direction. The anvil 72 is accommodated in an anvil guide hole 91a of the case 91 so as to be movable in the vertical direction.
Further, the anvil 72 is mounted on the upper end of the rod 92a of the cylinder device 92. Therefore, by contracting the rod 92a of the cylinder device 92, the anvil 72 is driven in the up-down direction.
The upper end face of the anvil 72 has: pressing surfaces 72a for pressing the left and right reinforcing films F against the lower surfaces of the left and right tapes T of the fastener chain C; and a cutting blade 72b formed at an edge of the pressing surface 72a on the side of the cutting portion 50 and cutting the reinforcing film tape Ft.
Further, an element receiving groove 73 is formed in a pressing surface 72a which is an upper end surface of the anvil 72, and the element receiving groove 73 receives the left and right element rows EL of the fastener chain C when the anvil 72 moves upward. The element accommodating groove 73 is formed along the chain conveying direction. Therefore, the pressing surface 72a of the anvil 72 is divided into two left and right parts by the element receiving groove 73. That is, the left and right reinforcing film tapes Ft are cut at the left and right pressing surfaces 72a, and the cut left and right reinforcing films F are bonded to the lower surfaces of the left and right tapes T, respectively.
As shown in fig. 3, a mounting block 14 is fixed to the front plate 12a of the lower bracket 12, and a box 91 of the anvil unit 90 is fixed to a front surface (left side surface in fig. 3) of the mounting block 14. Further, the cutting portion 50 and the housing 61 of the clamp 60 are fixed to the rear surface (right side surface in fig. 3) of the case 91.
Next, the operation of the reinforcing-film bonding apparatus 10 according to the present embodiment will be described with reference to fig. 9 to 13.
First, as shown in fig. 9, in a state where the film holding member 45 has moved downward (in a state where the reinforcing-film tape Ft is held), the gripper 41 moves forward (to the left side in fig. 9), and thereby the left and right reinforcing-film tapes Ft are fed out into the anvil guide hole 91a of the case 91. At this time, the space SP of the fastener chain C is stopped at a predetermined position of the film adhering portion 70 by the chain conveying device 20. The timing of stopping the conveyance of the fastener chain C is arbitrary, and may be a period other than the timing of adhering the cut reinforcing film F to the tape T by the anvil 72.
Next, as shown in fig. 10, the cam shaft 64 rotates to move the left and right clamp pins 62 upward, and the left and right reinforcing film tapes Ft are fixed between the tip ends of the clamp pins 62 and the top surfaces of the fork insertion holes 51. At this time, the film holding member 45 moves upward to release the holding of the left and right reinforcing film tapes Ft.
Next, as shown in fig. 11, in a state where the film gripping member 45 has moved upward (a state where the reinforcing film tape Ft has not been gripped), the gripper 41 is retracted (moved to the right side in fig. 11). Thereby, the film guide member 42 of the clamper 41 is retracted from the anvil guide hole 91a of the case 91.
Next, as shown in fig. 12, the anvil 72 moves upward, the left and right reinforcing film tapes Ft are cut, and the cut left and right reinforcing films F are conveyed to the lower surfaces of the left and right tapes T of the fastener chain C, respectively. At this time, since the ultrasonic horn 71 moves downward, the left and right tapes T and the left and right reinforcing films F are sandwiched between the ultrasonic horn 71 and the anvil 72, and the left and right reinforcing films F are bonded to the left and right tapes T, respectively, by the oscillation of the ultrasonic horn 71. In addition, at this time, the left and right clamp pins 62 and the film holding member 45 move downward.
Next, the ultrasonic horn 71 moves upward and the anvil 72 moves downward to release the sandwiching of the fastener chain C, and then the fastener chain C is conveyed to the downstream side by the chain conveying device 20. Then, by repeating the above operation, the reinforcing film F is continuously adhered to the fastener chain C at the intervals SP provided at every predetermined interval.
As described above, the reinforcing film bonding apparatus 10 according to the present embodiment includes: a chain conveying device 20 which intermittently conveys the fastener chain C; a film supply unit 30 that supplies left and right reinforcing film tapes Ft to the lower surface of the fastener chain C along the conveying direction of the fastener chain C; and a film bonding part 70 for cutting the left and right reinforcing film tapes Ft supplied from the film supply part 30 and bonding the cut left and right reinforcing films F to the lower surface of the fastener chain C, thereby bonding the reinforcing films F to the lower surface of the tape T of the concealed slide fastener.
Further, according to the reinforced film bonding apparatus 10 of the present embodiment, since the clamp apparatus 60 is provided, and the left and right reinforced film tapes Ft fed out in the conveying direction of the fastener chain C by the film conveying apparatus 40 are fixed by the clamp apparatus 60, the left and right reinforced film tapes Ft can be cut into the left and right reinforced films F of a fixed length.
In addition, according to the reinforcing film bonding apparatus 10 of the present embodiment, the clamper 41 includes: the film guide member 42 that guides the movement of the left and right reinforcing film tapes Ft and the film gripping member 45 that can grip the left and right reinforcing film tapes Ft on the film guide member 42 are provided, the film guide member 42 includes left and right guide forks 43 that support the left and right reinforcing film tapes Ft from below, and the film gripping member 45 includes left and right gripping forks 46 that grip the left and right reinforcing film tapes Ft between the left and right guide forks 43.
In addition, according to the reinforced film bonding apparatus 10 of the present embodiment, since the film insertion holes 43b into which the left and right reinforced film tapes Ft are inserted are formed in the left and right guide forks 43, the left and right reinforced film tapes Ft can be inserted between the left and right guide forks 43 of the film guide member 42 and the left and right gripping forks 46 of the film gripping member 45, respectively.
The present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the scope of the present invention.
For example, in the present embodiment, an example has been described in which the anvil is disposed below the transfer line of the fastener chain and the reinforcing film tape is cut by the anvil, but the present invention is not limited to this, and an ultrasonic horn may be disposed below the transfer line and the reinforcing film tape may be cut by the ultrasonic horn.
