Further, the continuous chain C1 is supplied to the slide fastener assembling device 10 with the lower stop portion P2 of the continuous chain C1 as the downstream side. The upstream side or the downstream side is based on the conveying direction of the continuous chain C1. Further, the continuous chain C1 is cut by the feed cutter 21 at a predetermined position in the space S.

The gripper 20 grips the chain C2 at the position of the feed cutter 21 and releases the grip of the chain C2 at the position of the non-defective product ejector 25 or the non-defective product ejector 26. As shown in fig. 3 and 4, the gripper device 20 includes a pair of left and right grippers 20a, and the pair of left and right grippers 20a grips the upper end portions of the left and right fastener tapes T of the chain C2. Further, 6 clamp devices 20 are arranged on the upper surface of the rotating disk 13 at equal intervals in the circumferential direction. The chain C2 gripped by the left and right grippers 20a is suspended in the vertical direction by gravity.

As shown in fig. 3 and 4, the slider mounting device 30 includes: a slider holding device 31 for holding the slider SL; and a drive device, not shown, attached to the fixed tray 15 and driving the slider holding device 31 in the vertical direction.

The slider holding device 31 includes: a housing 40 having a cross section コ with an open lower side; a front arm (1 st arm) 41 and a rear arm (2 nd arm) 42 whose upper portions are housed in the housing 40 and which are provided so as to be openable and closable in the front-rear direction; a pile member 43 vertically penetrating the housing 40 and driven to open the front arm 41 and the rear arm 42; a driving cylinder device, not shown, attached to the housing 40 and driving the pile member 43 in the vertical direction; and an extension spring 45 that is stretched between the front arm 41 and the rear arm 42 and biases the front arm 41 and the rear arm 42 to close. In fig. 4 and 6, the structure on the front arm 41 side is not shown for easy understanding of the drawings. In fig. 3, 5, 7, 9, 11, and 13, a partial structure is shown in cross section.

The upper end of the front arm 41 is swingably supported by the housing 40 via a support pin 41 a. Further, the front arm 41 is provided with a roller 41b which contacts the cam surface 43a of the pile member 43. Further, an adjustment bolt 46 is provided on the front arm 41, and the adjustment bolt 46 adjusts the distance between the front arm 41 and the rear arm 42 in the closed state.

Further, at the lower end of the front side arm 41, there are provided: the first retainer 1 is configured to hold the upper panel D3 side of the slider SL to which the tab PT is attached, and the lock release device 60 configured to release the lock of the slider SL.

The upper end of the rear arm 42 is swingably supported by the housing 40 via a support pin 42 a. Further, the rear arm 42 is provided with a roller 42b which contacts the cam surface 43a of the pile member 43.

Further, at the lower end of the rear arm 42, there are provided: a 2 nd holder 70 for holding the lower blade D1 side of the slider SL, and a release device 80 for releasing the holding of the slider SL by the 2 nd holder 70.

As shown in fig. 3, the 1 st holder 50 has: an accommodating space 51 for accommodating therein the pull piece PT of the slider SL held by the slider holding device 31; and an inclined surface 52 for controlling the pull tab PT to a predetermined posture. The 1 st retainer 50 is mounted on a housing 61 of a lock releasing device 60 described later. Further, the 1 st retainer 50 is disposed below the locking member L of the slider SL on the upper wing plate D3 side of the slider SL held by the slider holding device 31.

The inclined surface 52 is a rear surface forming a part of the housing space 51, and is formed to be inclined downward at a predetermined angle forward and downward from a lower position of the locking member L of the slider SL held by the slider holding device 31. Therefore, the tab PT that is caught on the inclined surface 52 is arranged obliquely downward in a direction away from the upper panel D3 with the lock member L as a base point. That is, the inclined surface 52 can control the tab PT to a predetermined posture.

As shown in fig. 3, the lock release device 60 includes: a housing 61 attached to the front arm 41; a slide member 62 attached to the housing 61 so as to be movable in the front-rear direction; a pressing member 63 attached to one surface (a lower surface of the slide member 62 in fig. 3) of the slide member 62 in the vertical direction, and configured to press the attachment portion D6 of the slider SL toward the 2 nd holder 70 to fix the slider SL; a lock releasing member 64 which is swingably attached to the slide member 62 and which is engaged with the pull tab PT of the slider SL to release the lock; a 1 st cylinder device (1 st driving device) 65 attached to the housing 61 and moving the slide member 62 in the front-rear direction; a 2 nd cylinder device (2 nd driving device) 66 attached to the other surface (the upper surface of the slide member 62 in fig. 3) of the slide member 62 in the vertical direction and driving the lock releasing member 64. The pressing member 63 and the lock releasing member 64 are attached to the slide member 62, and therefore move in the left-right direction together with the slide member 62.

The pressing member 63 is a rod-shaped member extending in the front-rear direction, and a cutout 63a having a shape similar to the shape of the attachment portion D6 of the slider SL is formed at one end (the right end in fig. 3).

The lock releasing member 64 is a rod-shaped member extending in the front-rear direction, and has a hook portion 64a formed at one end (right end in fig. 3), and the hook portion 64a can enter into the coupling ring PT1 of the tab PT and engage with the grip portion PT 2. The intermediate portion of the lock releasing member 64 is supported by a support pin 64b so as to be swingable in the vertical direction. Therefore, the lock releasing member 64 rocks in the up-down direction, thereby causing the hook portion 64a to move in the up-down direction.

Further, a compression spring 64c that presses the other end of the lock release member 64 downward is provided between the upper surface of the other end (left end in fig. 3) of the lock release member 64 and the lower surface of the slide member 62. Therefore, when the lock release member 64 is not moved downward by the 2 nd cylinder device 66, the state of being moved upward is maintained by the biasing force of the compression spring 64c (see fig. 3, 5, and 7). At this time, the lock releasing member 64 is in an initial state, and the upper surface of the lock releasing member 64 is substantially parallel to the lower surface of the pressing member 63 in the front-rear direction.

The 1 st cylinder device 65 is configured to drive the cylinder piston rod 65a in the front-rear direction. A slide member 62 is attached to a distal end portion of the drive cylinder rod 65 a. Therefore, the 1 st cylinder device 65 can move the slide member 62 (i.e., the pressing member 63 and the lock release member 64) in the front-rear direction by extending and contracting the cylinder rod 65a (see fig. 7).

The 2 nd cylinder device 66 is configured to drive the cylinder rod 66a in the up-down direction. A cushion member 66b for pressing the lock releasing member 64 is attached to a distal end portion of the cylinder rod 66 a. Therefore, the 2 nd cylinder device 66 can move the lock release member 64 upward by contracting the cylinder piston rod 66a (see fig. 3, 5, and 7), and can move the lock release member 64 downward by extending the cylinder piston rod 66a (see fig. 9).

As shown in fig. 3 and 4, the 2 nd retainer 70 includes: a base plate 71 attached to the rear arm 42; and a pair of left and right slider holding members 72 for holding the slider SL, the pair of left and right slider holding members 72 being provided on one surface (left side surface in fig. 3) of the base plate 71 in the front-rear direction.

The intermediate portions of the left and right slider holding members 72 are supported by the base plate (base) 71 so as to be rotatable in the left-right direction by support pins 72 a. Further, in the lower portion of the left and right slider holding members 72 below the support pin 72a, a pocket 73 capable of accommodating the lower blade D1 of the slider SL is provided. The pocket 73 is divided into two parts, i.e., left and right parts, and is formed in the left and right slider holding members 72.

Further, compression springs 74 are provided at upper side portions of the left and right slider holding members 72 above the support pins 72a, and the compression springs 74 urge lower side portions of the left and right slider holding members 72 below the support pins 72a in a direction to approach each other. Thus, when the left and right pockets 73 of the slider holding members 72 are not separated from each other by the release device 80, the closed state is maintained by the biasing force of the compression spring 74 (see fig. 4 and 6). Further, a pair of regulating pins 71a are attached to the base plate 71, and the pair of regulating pins 71a regulate the rotational position of the left and right slider holding members 72 in the closed state of the pocket 73. Further, at the lower ends of the left and right slider holding members 72, cam followers 75 are formed which come into contact with cam members 81 of a release device 80 described later, respectively.

As shown in fig. 3 and 4, the release device 80 includes: a cam member 81 provided on the other surface (the right surface in fig. 3) in the front-rear direction of the base plate 71 so as to be movable in the vertical direction; and a cam driving member 85 that moves the cam member 81 in the vertical direction.

The cam member 81 is a rod-like member extending in the vertical direction, and has a cam 82 formed at its lower end toward the front, and the cam 82 contacts the cam followers 75 of the left and right slider holding members 72. The cam 82 has a triangular cross section, and left and right surfaces thereof form a pair of cam surfaces 82a that contact the cam followers 75 of the left and right slider holding members 72. Further, a cam drive lever 83 contactable with the cam drive member 85 is attached to an upper end of the cam member 81 toward the rear.

The cam driving member 85 includes: a stay 86 attached to the fixed stand 14; and a fixing lever 87 attached to a front end portion (left end portion in fig. 3) of the stay 86 and capable of contacting the cam driving lever 83. The fixing lever 87 is disposed in the left-right direction so as to be orthogonal to the cam driving lever 83.

The operation of the slider attaching device 30 configured as described above will be described below. First, the pile member 43 moves upward, and thereby the front arm 41 and the rear arm 42 of the slider holding device 31 are closed as shown in fig. 3 and 4.

Next, the slider SL is placed in the pocket 73 of the 2 nd holder 70 of the slider holding device 31 from above by a slider feeding device, not shown, as shown in fig. 5 and 6. At this time, the slider SL is sandwiched by the left and right slider holding members 72 and is sandwiched by the 1 st holder 50 and the 2 nd holder 70. At this time, the tab PT of the slider SL enters the housing space 51 of the 1 st holder 50, and is brought into a predetermined oblique posture by the inclined surface 52 of the 1 st holder 50 (see fig. 8).

Next, as shown in fig. 7 and 8, the 1 st cylinder device 65 of the lock release device 60 moves the slide member 62 toward the 2 nd holder 70, and the pressing member 63 presses the slider SL to fix the slider SL to the 2 nd holder 70.

Next, as shown in fig. 9 and 10, the 2 nd cylinder device 66 of the lock release device 60 moves the lock release member 64 downward, whereby the hook portion 64a of the lock release member 64 enters the connection ring PT1 of the tab PT, engages with the C-shaped gripping portion of the gripping portion PT2, and pulls down the tab PT. Thereby, the lock member L is lifted up, and the lock is released.

Next, as shown in fig. 11, the slider holding device 31 is moved downward by a driving device, not shown, and thereby the left and right element rows EL of the fastener chain C2 are inserted into the slider SL held by the slider holding device 31. Thereby, the slider SL is attached to the fastener C2.

In addition, at this time, as shown in fig. 11, the cam driving lever 83 of the cam member 81 of the releasing device 80 is in contact with the fixing lever 87 of the cam driving member 85, and thus the cam member 81 is moved upward with respect to the 2 nd holder 70. As a result, as shown in fig. 12, the left and right cam surfaces 82a of the cam 82 of the cam member 81 come into contact with the cam followers 75 of the left and right slider holding members 72, and the lower end portions of the left and right slider holding members 72 are pushed apart at intervals against the biasing force of the compression spring 74. Therefore, the pockets 73 of the left and right slider holding members 72 are opened, and the grip of the slider SL is released. Further, thereafter, the 2 nd cylinder device 66 moves the lock release member 64 upward, and the 1 st cylinder device 65 moves the slide member 62 to the initial position.

Next, as shown in fig. 13, the stub 43 is moved downward, whereby the front side arm 41 and the rear side arm 42 of the slider holding device 31 are opened in the front-rear direction. Thereafter, the slider holder 31 is moved upward by a drive device, not shown. Thereby, the slider holding device 31 is retracted above the rotation range of the clamping device 20, and the rotating disk 13 can be rotated. By repeating the above-described operation, the slider SL can be attached to all the stringers C2 conveyed to the slider attaching device 30.

As described above, according to the slider mounting device 30 of the present embodiment, the slider holding device 31 includes: a front arm 41 and a rear arm 42 that open and close in the front-back direction of the fastener chain C2; a 1 st retainer 50 attached to the front arm 41 and holding the slider SL on the side of the upper blade D3; a 2 nd holder 70 attached to the rear side arm 42 and holding the slider SL on the side of the lower panel D1; and a lock release device 60 attached to the front arm 41 and releasing the lock of the slider SL, wherein the 1 st holder 50 has an inclined surface 52 that controls the tab PT of the slider SL to a predetermined posture, and the lock release device 60 includes: a housing 61 attached to the front arm 41; a slide member 62 attached to the housing 61 so as to be movable in the front-rear direction; a pressing member 63 attached to the lower surface of the slide member 62, for pressing the slider SL toward the 2 nd holder 70 to fix the slider SL; a lock releasing member 64 which is swingably attached to the slide member 62 and which is engaged with the pull tab PT of the slider SL to release the lock; a 1 st cylinder device 65 attached to the housing 61 and moving the slide member 62; and a 2 nd cylinder device 66 which is attached to an upper surface of the slide member 62 and drives the lock releasing member 64. Therefore, the slider SL with the automatic locking function can be attached to the fastener chain C2.

In the slider attaching device 30 according to the present embodiment, since the cutout 63a having a shape similar to the shape of the attaching portion D6 of the slider SL is formed in the pressing member 63, the slider SL can be reliably fixed to the 2 nd holder 70.
