Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a residual wire processing device that processes residual wire on a spool carried out from a wire twisting machine so as to remove it from the spool.

Conventionally, in order to take out the remaining wire on the spool from the spool, the remaining wire was taken out from a plurality of spools together in a coil shape using a bundling machine, and this bundle of remaining wire was placed in a box for disposal. However, with this processing method, the end of the residual line will pop out and be exposed, making the work dangerous. In addition, since multiple spools are processed at the same time and the spools rotate on rollers, there is considerable noise, and furthermore, it is difficult to collect the bundle. The later waste wire had a low space factor and a large box was required, making it difficult to transport.

The purpose of the present invention is to be able to safely dispose of residual wire without generating noise, to dispose of scrap wire with a high space factor, and to avoid any hindrance to loading and unloading the spool. To provide a residual line processing device that can be installed in a small space without any problems.

Embodiments of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 schematically show a residual line processing device 10 according to the present invention.
1 is a spool positioning means 18 which is attached to the machine frame 12 and consists of a pair of spindles 16 and 16' which receives and rotatably supports the spool 14 on which the residual line 1 remains from the conveyor 13, and the end of the residual line on the spool. Clamping means 20 for grasping and pinching out
The apparatus is provided with a residual wire feeding means 22 for feeding the residual wire picked out in this way, and a cutter means 24 for cutting the residual wire fed in this way into a predetermined short length.

The clamping means 20 is a vertical guide mechanism 2 attached to the machine frame 12, as shown in FIGS. 3 to 5.
5 and a clamp 28 attached via a horizontal guide mechanism 26. The vertical guide mechanism 25 includes a pair of vertical guides 30 attached to the machine frame 12,
30' and vertically movable by a piston rod 32 (see FIG. 5) of a cylinder (not shown) also mounted on the machine frame 12, and a horizontal guide mechanism 26. consists of a horizontal guide frame 40 which is slidably attached to a pair of horizontal guides 36, 36' attached to the vertical guide frame 34 and horizontally moved by a cylinder 38 also attached to the vertical guide frame 34. The clamp 28 consists of a fixed jaw 42 and a movable jaw 42', as shown in FIG.
4 to the fixed jaw 42 via a link 46. As can be seen from FIG. 4, the clamp 28 of the clamping means 26 is provided with a touch sensor 92 that comes into contact with the end of the residual line 1 thereon as the spool 14 rotates. A command to stop the rotation of 14 is generated.

As shown in FIGS. 6 and 7, the residual wire feeding means 22 is composed of a fixed pinch roll 48 and a movable pinch roll 50 that moves toward and away from the fixed pinch roll 48. The fixed pinch roll 48 is integrally attached to a central shaft 49, which is rotatably supported by the machine frame 12 through bearings 51, 51' and connected to a motor 52 through a coupling 54. The movable pinch roll 50 is attached to a linear guide mechanism 55, and this linear guide mechanism 55 is slidably attached to a pair of linear guide rails 56, 56' rotatably supported by a central shaft 49, and is moved by a cylinder 58. It consists of a block 60 that moves linearly, and a movable pinch roll 5.

1 consists of a cylinder 64 that is swingably supported on a machine frame 12 at a fulcrum 62, and its piston rod 64
a is connected to linear guide rails 56, 56'. Therefore, by expanding and contracting the piston rod 64a of this cylinder 64, the movable pinch roll 50 that engages with the fixed pinch roll 48 is reciprocated around the central axis 49 along the outer peripheral surface of the fixed pinch roll 48 towards the cutter means 24 side. Can be rotated. Note that a seventh

is fixedly arranged, but the remaining line guide rod 68' is moved by the cylinder 70 to the remaining line guide rollers 66, 6.
6', 68 so as to be openable and closable.

As shown in FIGS. 8 to 10, the cutter means 24 includes a fixed blade 74 attached to the machine frame 12 via a bracket 72, and a fixed blade 74 attached to a rotating body 75 rotatably supported by the bracket 72. The rotating body 75 is connected to a motor 86 on the machine frame 12 via a pulley 80 attached to its rotating shaft 78, a belt 82, and a pulley 84. As can be seen from FIG. 11, the cutter means 24 is disposed within the chute 88 to drop the cut waste wire 1a into the waste box 90.

Next, the operation of the residual line processing device of the present invention will be described in detail with reference to FIG. 11 and FIGS. 3 to 10. When the sensor detects that the spool 14 has reached a predetermined position in the residual line processing device 10, the conveyor 1
3 stops to hold the spool 14 in this predetermined position. At this time, the spindles 16, 16' protrude to rotatably support and position the spool 14. Note that the end of the remaining line 1 is the flange 1 of this spool 14.
It is locked in hole 4a. Then, the vertical guide mechanism 25 of the clamping means 20 operates to move the clamp 2

Move horizontally to Thereafter, when the spool 14 rotates and the end of the residual line 1 comes into contact with the touch sensor 92 provided on the clamp 28, the rotation of the spool 14 is stopped. At this time, the movable jaw 4 of the clamp 28
2' is closed by the operation of the cylinder 44 so as to grip the end of the residual line 1. When the clamp 28 is moved from position C to position B by the horizontal guide mechanism 26 while the end of the remaining line 1 is gripped by the clamp 28, the end of the remaining line 1 is held on the spool 1.

8 is from position B to position A by the operation of the vertical guide mechanism 25.
rise to At this time, since the residual line guide rod 68' located below the residual line feeding means 22 is open, the residual line 1 raised by the clamp 28 is placed between the residual line guide rollers 66, 66', and 68. Thereafter, the residual line guide rod 68' is closed toward the residual line guide roller 66 so as to surround the residual line 1 by the operation of the cylinder 70. Next, the movable pinch roll 50 of the remaining line feeding means 22 is moved to the remaining line by the operation of the cylinder 58.
is moved from position D to position E in FIG. 11 so as to engage the fixed pinch roll 48 with the clamp 28 between them, and at the same time, the movable jaw 42' of the clamp 28 opens from the fixed jaw 42 to release the grip on the residual line 1. . On the other hand, the cylinder 64 of the residual wire feeding means 22 is operated and the block 6
0 about the fulcrum 62, the movable pinch roll 50 rotates around the fixed pinch roll 48 and feeds the residual wire 1 toward the cutter means 24. Therefore, the cutter means 24 has rotary blades 76, 7
6', the residual wire 1 is shredded by the fixed blade 74 for each feeding length of the residual wire feeding means 22, and a large number of scrap wires 1a thus formed are sent to the chute 8.
8 and fall into the waste box 90. Spool 1
When the remaining line 1 on 4 disappears, the spool 14 stops, detecting this, the movable pinch roll 50 is returned to position D, and at the same time, the spindles 16, 1
6' retreats to place the spool 14 on the conveyor 13, and as the conveyor 13 moves, the spool 14 that has been left marked is carried out, and at the same time, the next spool 14 to be left marked is placed in the marking processing device 10. It is carried in and the above operation is repeated.

According to the present invention, as described above, the residual line processing is performed automatically, so it is safe and improves work efficiency, and the operating environment is improved because the noise is extremely low. Since it is shredded into pieces, it has the practical benefit of improving its space factor and making it easier to transport. In particular, the device of the present invention pulls out the residual wire in the spool upwards using the clamping means and shreds it, making it possible to effectively utilize the space three-dimensionally. Since the cutting process is carried out by pulling the residual line above the spool, the spool can be loaded and unloaded by horizontally moving the spool without being hindered by the residual line processing device. The residual wire pulled upward by the clamping means is bent in an arc around the fixed pinch roll from just above the spool and guided laterally to shred it, so that the scrap wire does not fall onto the spool. , post-processing such as storage and transportation of scrap wire can be easily performed. Furthermore, since the movable pinch roll of the residual line feeding means slides around the fixed pinch roll to bend and feed the residual line at the same time, there is no need to use separate means for bending and feeding. The overall structure is simple and inexpensive, and work can be performed efficiently and reliably.
