The first pinch roller 23b moves in a direction away from the first drive roller 23a and a direction in contact with the first drive roller 23a. For example, the first cylinder 45 is erected upward on the base 41, and the first bracket 46 is attached to the first piston rod 45 a of the first cylinder 45. The first pinch roller 23b is attached to the first bracket 46 so as to be rotatable by a horizontal shaft 47.

Thereby, the 1st pinch roller 23b moves toward the 1st drive roller 23a with the 1st bracket 46 by extending | stretching the 1st piston rod 45a of the 1st cylinder 45. FIG.
By contracting the first piston rod 45a of the first cylinder 45, the first pinch roller 23b moves away from the first drive roller 23a together with the first bracket 46.

The second holding body 51 is positioned below the conveyance path 21, and the second holding body 51 moves in the vertical direction in a direction approaching and separating from the first holding body 50. For example, the second cylinder 52 is erected on the base 41, and the second piston rod 52 a of the second cylinder 52 is connected to the second holding body 51.
When the second piston rod 52 a of the second cylinder 52 is extended, the second holding body 51 moves in a direction approaching the first holding body 50.
By contracting the second piston rod 52 a of the second cylinder 52, the second holding body 51 moves in a direction away from the first holding body 50.

By moving the second holding body 51 toward the first holding body 50, the second slider 12 is sandwiched between the lower surface 50 a of the first holding body 50 and the upper surface 51 a of the second holding body 51. Accordingly, the first holding body 50 and the second holding body 51 hold the second slider 12 so as not to move in the transport direction, the width direction, and the vertical direction.
For example, the lower surface 50 a of the first holding body 50 has a recess in which the upper portion of the second slider 12 is fitted. The lower surface of the second slider 12 is pushed by the upper surface 51 a of the second holding body 51, and the second slider 12 is pushed and held in the recess of the first holding body 50. Accordingly, the second slider 12 is sandwiched and held between the first holding body 50 and the second holding body 51.

The cutting unit 28 includes a first cutter 55 and a second cutter 56.
The first cutter 55 is attached above the transport path 21 so as to move in the vertical direction.
The second cutter 56 is attached below the transport path 21 so as to move in the vertical direction. The second cutter 56 is located directly below the first cutter 55.
The third cylinder 57 is attached to the first vertical frame 42 in the vertical direction. The first cutter 55 is attached to the third piston rod 57 a of the third cylinder 57.
The fourth cylinder 58 is attached to the base 41 in the vertical direction. The second cutter 56 is attached to the fourth piston rod 58a of the fourth cylinder 58.

The widths of the first cutter 55 and the second cutter 56 are larger than the width of the pair of fastener tapes 4 of the fastener chain 1.
By extending the third piston rod 57a of the third cylinder 57 and lowering the first cutter 55, and extending the fourth piston rod 58a of the fourth cylinder 58 and raising the second cutter 56, the first cutter 55 And the second cutter 56 cut the pair of fastener tapes 4 of the fastener chain 1.

The chain moving unit 31 has a gripper 60 that holds and releases the fastener tape 4 of the fastener chain 1. The gripper 60 reciprocates in the transport direction across a first position upstream of the cutting portion 28 in the transport direction and a second position downstream of the feed roller 23 in the transport direction.
The gripper 60 moves in a direction approaching the fastener chain 1 and a direction away from the fastener chain 1 in the first position and the second position.
Thereby, the fastener chain 1 on the upstream side in the transport direction with respect to the cut portion of the fastener chain 1 cut by the cutting portion 28 can be transported to the downstream side in the transport direction of the feed roller 23 by the gripper 60.

The chain transfer unit 31 includes a first guide 61 attached toward the conveyance direction near the other end in the width direction of the base 41.
A first moving body 62 is movably provided along the first guide 61.

A second moving body 64 is provided so as to be movable in the width direction along the second guide 63, and the plate 65 is horizontally attached to the upper surface of the second moving body 64.
The second bracket 66 is attached to the plate 65, and the gripper 60 is attached to the second bracket 66.
The gripper 60 has a pair of upper and lower gripping claws (not shown). By swinging the pair of upper and lower gripping claws in the approaching direction, the gripper 60 performs a gripping operation, and by swinging in the direction of separating the pair of upper and lower gripping claws, the gripper 60 performs a gripping and releasing operation.

The transfer operation of the fastener chain 1 by the chain transfer unit 31 will be described.
The first moving body 62 is moved to the upstream side in the transport direction, and the gripper 60 is brought into the grip release state at the first position.
The second moving body 64 is moved in the direction approaching the fastener chain 1 along the second guide 63, and one gripping claw is on the fastener tape 4 and the other gripping claw is below the fastener tape 4.
The pair of gripping claws are swung in the approaching direction, and the gripper 60 grips the fastener tape 4.

The gripper 60 is moved to the second position by moving the first moving body 62 along the first guide 61 to the downstream side in the transport direction.
As a result, the gripped fastener chain 1 is transferred to the downstream side in the transport direction from the feed roller 23.
The gripper 60 swings away from the pair of gripping claws, and the gripper 60 grips and releases the fastener tape 4.
The gripper 60 moves away from the fastener chain 1 by moving the second moving body 64 along the second guide 63 in a direction away from the fastener chain 1.
The gripper 60 is moved to the first position by moving the first moving body 62 along the first guide 61 to the upstream side in the transport direction.

That is, the gripper 60 moves along a plane rectangular trajectory. Thus, after the fastener chain 1 is cut by the cutting portion 28, the fastener chain 1 on the upstream side in the transport direction from the cut portion is transferred by the gripper 60 to the downstream side in the transport direction from the feed roller 23.

The space detection unit 32 detects the space of the fastener chain 1 conveyed toward the cutting unit 28 along the conveyance path 21 on the upstream side of the cutting unit 28 in the conveyance direction, and outputs a detection signal.
The space detection unit 32 has a pair of width direction guides 70 through which the fastener chain 1 passes.
The pair of guides 70 is swingable along a horizontal plane by a vertical shaft 71, and the pair of guides 70 is swingingly biased by a spring or the like not shown in the direction in which the opposed inner side surfaces 72 approach each other. 70 is an approaching state.

When the pair of guides 70 are in the approaching state, the detector 73 outputs a detection signal.
The detector 73 is attached to a third bracket 74 erected on the base 41. A detection rod 75 is attached to one guide 70, and the detection piece 75 a of the detection rod 75 faces the detector 73.
When the pair of guides 70 are in the approaching state, the detection piece 75a approaches the detector 73, and the detector 73 outputs a detection signal. That is, the detector 73 is a non-contact type.
When the pair of guides 70 overcomes the spring force and swings in the direction in which the inner surface 72 is separated, the detection piece 75 a is separated from the detector 73. Thereby, the detector 73 does not output a detection signal.

As shown in FIG. 12, the inner surface 72 of the guide 70 includes a first surface 72a at the upstream end in the transport direction, a second surface 72b upstream in the transport direction, a third surface 72c downstream in the transport direction, and a transport direction. It has a fourth surface 72d at the downstream end.
The first surface 72 a has a bowl shape and forms a wide first gap 76 a between the first surfaces 72 a of the pair of guides 70.
The second surface 72b is linear along the transport direction, and a narrow second gap 76b is formed between the second surfaces 72b of the pair of guides 70.
The third surface 72c is inclined with respect to the transport direction, and the third gap 76c between the third surfaces 72c of the pair of guides 70 is gradually narrowed toward the downstream side in the transport direction.
The fourth surface 62d has a bowl shape and forms a wide fourth gap 76d between the fourth surfaces 72d of the pair of guides 70.
When the pair of guides 70 are in the approaching state, the width of the second gap 76 b is the same as the width of the element 5 of the fastener chain 1.
The pair of guides 70 has a groove 77 opened in the inner side surface 72. When the pair of guides 70 are in the approaching state, the width between the pair of grooves 77 is the same as the width of the fastener chain 1.

In the fastener chain 1, as shown in FIG. 13, the fastener tape 4 is inserted through the groove 77 of the guide 70, and the element 5 is inserted between the inner side surfaces 72 of the pair of guides 70.
When the third surface 72c of the inner surface 72 of the guide 70 is in contact with both end surfaces in the width direction of the element 5, the pair of guides 70 swings in the direction in which the inner surface 72 is separated from the shaft 71, and the pair of guides 70 are It becomes a separated state.
Thereby, since the detection piece 75a of the detection rod 75 is separated from the detector 73, the detector 73 does not output a detection signal.

As shown in FIG. 11, the fastener chain 1 is conveyed along a pair of guides 70. At this time, the pair of guides 70 are in a separated state.
When the second space 7 from which the element 4 of the fastener chain 1 is removed reaches the pair of guides 70 and the second space 7 moves to the third gap 76c, the third surface 72c of the inner side surface 72 of the guide 70 becomes the element. No contact with 5.
As a result, the pair of guides 70 swings in the direction in which the inner side surface 72 approaches, and the pair of guides 70 enters the approaching state shown in FIG.
When the pair of guides 70 are in the approaching state, the detection piece 75a of the detection rod 75 approaches the detector 73 as shown in FIG. 12, and the detector 73 outputs a detection signal.
A detection signal output from the detector 73 detects that the second space 7 of the fastener chain 1 has reached the pair of guides 70.

The space detection unit 32 includes a third guide 80. The third guide 80 is attached near the one end of the base 41 in the width direction as directly below the conveyance path 21.
A third moving body 81 is movably provided along the third guide 80, and a column 82 is attached to the third moving body 81. A horizontal plate 83 is horizontally attached to the upper portion of the column 82, and a pair of guides 70 are swingably attached to the upper surface of the horizontal plate 83 by a shaft 71.

As such, by moving the third moving body 81 along the third guide 80, the space detection unit 32 moves to the space detection position upstream in the conveyance direction shown in FIG. It moves across the slider movement position on the downstream side.
Thereby, the space detection part 32 comprises the slider moving part 29 which moves the 1st slider 11 of the fastener chain 1 so that it may mention later.

The reverse feed roller 33 includes a second drive roller 33a and a second pinch roller 33b.
The second drive roller 33a is rotatably attached to the second vertical frame 43 with a horizontal axis. The second drive roller 33 a is rotated by a second motor 84 attached to the second vertical frame 43.
The second pinch roller 33b is rotatably attached to the arm 85. The arm 85 is attached to the second vertical frame 43 so as to be swingable in the vertical direction on a horizontal axis, and the arm 85 is swinged upward by a spring 86.
As a result, the second pinch roller 33b comes into pressure contact with the second drive roller 33a.

The guide roller 34 is attached to the second vertical frame 43 so as to be rotatable about a horizontal axis.
Thereby, the fastener chain 1 is guided by the guide roller 34 so as not to be displaced in the width direction. The fastener chain 1 further continues to the feed roller 23 through the reverse feed roller 33 and the pair of guides 70, and the fastener chain 1 is conveyed by being pulled by the feed roller 23. That is, the feed roller 23, the chain moving unit 31, and the reverse feed roller 33 are conveying means for conveying the fastener chain 1 along the conveying path 21.

The cutting operation of the fastener chain 1 will be described.
The fastener chain 1 is conveyed by the feed roller 23. At this time, the pair of guides 70 are in the separated state shown in FIG.
When the first space 6 of the fastener chain 1 reaches the third gap 76c of the pair of guides 70, the pair of guides 70 enters the approaching state shown in FIG.
Thereby, the detector 73 outputs a detection signal. The detection signal output from the detector 73 is sent to the controller 90.
The controller 90 outputs a deceleration command to the first motor 44, and the first motor 44 decelerates. Thereby, the conveyance speed of the fastener chain 1 is decelerated.

Furthermore, by conveying the fastener chain 1, the first space 6 passes through the third gap 76c of the pair of guides 70, and the fastener element 5 reaches the third gap 76c. The pair of guides 70 are separated from each other as shown in FIG. 13 by the fastener element 5, and the detector 73 does not output a detection signal. Thereby, it can be detected that the first space 6 of the fastener chain 1 has passed through the pair of guides 70.
And the butterfly stick 14 and the box stick 15 which are the release tools 16 attached to the fastener tape 4 in the first space 6 of the fastener chain 1 are the first notch 55a on the lower surface of the first cutter 55 of the cutting part 28, the first When moving to the second notch 56a on the upper surface of the two cutter 56, the first motor 44 is stopped, the rotation of the feed roller 23 is stopped, and the fastener chain 1 is stopped.
For example, the controller 90 sets a time for the fastener chain 1 to move to the aforementioned position after the detection signal is sent, and after the set time has elapsed, the controller 90 outputs a stop signal for the first motor 44 and rotates the feed roller 23. By stopping the operation, the fastener chain 1 is stopped.

In the state in which the fastener chain 1 is stopped, as shown in FIG. 14, the butterfly stick 14 and the box stick 15 which are the release tools 16 of the fastener chain 1 are connected to the first notch 55 a and the first blade 55 b of the first cutter 55. The first step 55c and the second step 56c between the second notch 56a and the second blade 56b of the second cutter 56 are located on the downstream side in the transport direction.
The first slider 11 of the fastener chain 1 passes through the guide 70, and the first slider 11 is positioned downstream of the guide 70 in the transport direction.

Next, the operation | movement which moves the 1st slider 11 of the fastener chain 1 to the top stop 13 is demonstrated.
Since the width of the first slider 11 of the fastener chain 1 is larger than the width of the element 5, when the first slider 11 passes through the third gap 76 c of the pair of guides 70, the pair of guides 70 is shown in FIG. 13. The inner surface 72 swings away from the approaching state shown.
When the first slider 11 passes through the third gap 76c of the pair of guides 70, the pair of guides 70 swing in the direction in which the inner side surface 72 approaches, so that the third surface of the guide 70 as shown in FIG. 72c is in contact with the element 5, and the pair of guides 70 are in an approaching state.
Thus, the first slider 11 that has passed through the pair of guides 70 cannot move to the upstream side in the transport direction through the gap between the inner side surfaces 72 of the pair of guides 70.

After the fastener chain 1 stops, the controller 90 outputs a rotation command for the second motor 84 and drives the second motor 84 to rotate the second drive roller 33a in the direction of the arrow.
As a result, the first slider 11 of the fastener chain 1 enters the fourth gap 76d of the pair of guides 70 as shown in FIG. 15, and the first slider 11 is held by the pair of guides 70.
In the state shown in FIG. 15, the pair of guides 70 (space detection unit 32) are space detection positions.
By moving the third moving body 81 downstream in the transport direction along the third guide 80, the pair of guides 70 moves downstream in the transport direction.
By moving the pair of guides 70, the first slider 11 moves along the fastener element 5 to the downstream side in the transport direction.
By moving the pair of guides 70 to the slider movement position, the first slider 11 moves until it comes into contact with the top stopper 13 (see FIG. 9B).

If the fastener chain 1 may move together with the first slider 11 when moving the first slider 11, as shown in FIG. 10, upstream of the pair of guides 70 in the conveyance path 21 in the conveyance direction. A clamper 91 is provided on the side. The fastener chain 1 is gripped by the clamper 91, and the fastener chain 1 is prevented from moving to the downstream side in the transport direction by the clamper 91.

After the pair of guides 70 have moved to the slider movement position, the third moving body 81 is moved along the third guide 80 to the upstream side in the transport direction, so that the pair of guides 70 is set as a space detection position. At this time, the first slider 11 does not move, and the first slider 11 remains in contact with the top stop 13.
That is, the space detection unit 32 also serves as the slider moving unit 29.

Next, the operation | movement which cut | disconnects the fastener tape 4 of the 1st space 6 of the fastener chain 1 is demonstrated.
The controller 90 outputs a rotation command for the second motor 84 and drives the second motor 84 to rotate the second drive roller 33a in the arrow direction. The fastener chain 1 moves to the upstream side in the conveying direction, and the butterfly stick 14 and the box stick 15 which are the release tools 16 attached to the fastener tape 4 in the first space 6 of the fastener chain 1 are shown in FIG. The first step 55c of the cutter 55 and the second step 56c of the second cutter 56 abut.
Thereby, the cutting position of the fastener chain 1 can be positioned with high accuracy by the first cutter 55 and the second cutter 56.
At this time, the first cutter 55 elongates the third piston rod 57a of the third cylinder 57 and moves in a direction approaching the conveyance path 21, and the first blade portion 55b of the first cutter 55 approaches the fastener tape 4. ing. The second cutter 56 extends the fourth piston rod 58 a of the fourth cylinder 58 and moves in a direction approaching the transport path 21, and the second blade portion 56 b of the second cutter 56 approaches the fastener tape 4.

The first cutter 55 and the second cutter 56 are moved in a direction approaching the conveyance path 21, and the first space 6 is formed by the first blade portion 55 b of the first cutter 55 and the second blade portion 56 b of the second cutter 56. The fastener tape 4 is cut (see FIG. 9C).
After cutting the fastener tape 4, the first cutter 55 and the second cutter 56 are moved in the direction away from the conveyance path 21.

After the fastener tape 4 is cut, the fastener chain 1 on the downstream side in the transport direction from the cut portion is transported by the feed roller 23 and discharged.
After the fastener tape 4 is cut, the fastener chain 1-1 on the upstream side in the transport direction from the cut portion is transferred to the feed roller 23 by the chain transfer portion 31 as described above (see FIG. 9C).
That is, the gripper 60 of the chain transfer section 31 is moved along the plane rectangular locus, and the fastener tape 4 of the fastener chain 1-1 is gripped by the gripper 60 and conveyed to the feed roller 23.

At this time, the first piston rod 45a of the first cylinder 45 is contracted to move the first pinch roller 23b away from the first drive roller 23a, and a gap is formed between the first drive roller 23a and the first pinch roller 23b. Form.
The fastener chain 1-1 that is gripped and transferred by the gripper 60 moves through the gap between the first drive roller 23a and the first pinch roller 23b to the downstream side in the transport direction from the feed roller 23.
Thereafter, the first piston rod 45a of the first cylinder 45 is extended to move the first pinch roller 23b in a direction approaching the first drive roller 23a, and the fastener chain is formed between the first drive roller 23a and the first pinch roller 23b. 1-1 is sandwiched.

Note that the fastener tape 4 of the fastener chain 1 may be held by the gripper 60 of the chain moving portion 31 before the fastener tape 4 in the first space 6 of the fastener chain 1 is cut.

An operation of moving the second slider 12 of the fastener chain 1 will be described.
The fastener chain 1-2 (see FIG. 9E) obtained by cutting the fastener tape 4 in the second space 7 of the fastener chain 1 is conveyed by the feed roller 23 and discharged.
At this time, the first slider 50 and the second holder 51 of the slider holder 30 hold the second slider 12.
