Description

Description: TECHNICAL FIELD The present invention relates to a residual wire treatment method for treating a residual wire on a spool delivered from a twisting machine or the like so as to remove it from the spool.

In the prior art, in order to take out the residual line on the spool from the spool, as shown in FIGS. 9 and 10, one or a plurality of spools 102 on which the residual line 101 remains is attached to an underroll type feeding device 104. Put on these multiple spools 1
The remaining wire 101 on 02 is bundled together with a remaining wire winding machine (bundling machine) 108 via a guide means 106 and wound into a coil to form a remaining wire bundle 1
The remaining wire bundle 110 was taken out as 10, and was put in a waste box 112 for processing as shown in FIG.

However, with such a processing method, the worker
2 Since the remaining wire 100 on the upper side is sent to the remaining wire winder 108 to be set, the work cannot be automated, so that the worker needs to wait at the work site, and therefore the last terminal of the remaining wire is the spool 102. If it jumps out when it comes off, it is likely to hit the worker and there is a danger in the work.Because a plurality of spools 102 are simultaneously processed by the underroll type feeding machine 104, the spool 102 underrolls the feeding machine 104. Since it rotates while dancing, there is a drawback that it makes a lot of noise.

Further, since the residual wire bundle 110 is processed by being put in the waste box 112 in the form of a coil, the space factor of the residual wire is low, and a large waste box is required, so that the transportability is low.

An object of the present invention is to provide a residual line processing method capable of automatically processing residual lines and safely, generating no noise, and processing waste lines at a high space factor. To do.

In order to solve the above problems, the present invention provides a spool positioning step of rotatably positioning a spool having a residual wire, and a residual portion which is searched for an end portion of the residual wire on the spool and is gripped by a clamp means. The wire gripping step, the residual wire transfer step of transferring the end of the residual wire gripped by the clamp means to the residual wire feeding means by the movement of the clamp of the clamp means, and the residual wire feeding means The residual wire feeding step of feeding the residual wire to the cutter means and the residual wire fed to the cutter means by the residual wire feeding means in this manner are sequentially performed by operating the cutter of the cutter means for each residual wire feeding amount. It is an object of the present invention to provide a residual wire treatment method, which comprises a residual wire shredding step of continuously shredding into a predetermined short length.

In this way, when the spool is positioned by the spool positioning means, the spool does not dance during rotation,
No noise is generated unlike the under-roll type feeding machine, the spool is positioned, the end of the residual line on the spool is searched and gripped, and the end of the residual line is transferred to the residual line feeding means. Since the remaining lines are sent to the cutter means and the remaining lines are shredded by the cutter means automatically and continuously, the remaining line processing can be automated, and therefore the worker stands by at the work site. Work is safe without the need for it. Further, since the remaining wire is shredded and stored in the waste box as a waste wire, the space factor of the waste box is improved.

An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows a residual line treatment apparatus 10 used for carrying out the residual line treatment method used in the present invention. The processing device 10 includes a spool positioning means 18 including a pair of spindles 16 and 16 'for rotatably supporting a spool 14 which is attached to a machine frame 12 and has a residual line 1 remaining thereon from a conveyor 13, and a spool positioning means 18 on the spool 14. Clamping means 20 for searching for and gripping the end portion of the residual line 1 of the residual line 1, and residual line feeding means 22 for feeding the end portion of the residual line picked up in this way to the cutter means described below, Remaining line 1 sent in this way

In the spool positioning means 18, the spool 14 has a conveyor 13
When it is conveyed on and aligned with the spindles 16 and 16 ', a position detection sensor such as a photoelectric switch (not shown) detects this and stops the conveyor 13, and the spindles 16,
16 'is driven to protrude so as to hold the spool 14, and the spool 14 is automatically rotatably positioned and supported.

As shown in FIGS. 2 to 4, the clamping means 20 includes a vertical guide mechanism 25 and a horizontal guide mechanism 26 attached to the machine frame 12.
It consists of a clamp 28 mounted via. The vertical guide mechanism 25 is a pair of vertical guides attached to the machine frame 12.
It consists of a vertical guide frame 34 that moves vertically by a piston rod 32 (see FIG. 4) of a cylinder (not shown) that is slidably attached to 30, 30 'and is also attached to the machine frame 12, and a horizontal guide mechanism. The reference numeral 26 comprises a horizontal guide frame 40 slidably mounted on a pair of horizontal guides 36, 36 'mounted on the vertical guide frame 34 and horizontally moved by a cylinder 38 also mounted on the vertical guide frame 34.

Therefore, the clamp 28 can be moved up and down or moved horizontally by the vertical guide mechanism 25 and the horizontal guide mechanism 26. This clamp 28, as shown in FIG.
It is composed of a fixed jaw 42 and a movable jaw 42 ', and the movable jaw 42' is opened and closed with respect to the fixed jaw 42 from a cylinder 44 via a link 46. This clamp 28, as shown in FIG.
It includes a touch sensor 92 mounted in the vicinity thereof, and this touch sensor 92 is used for the residual line 1 while the clamp 28 descends and moves horizontally.
Has a function of searching for the end of the remaining line 1 and when the end of the remaining line 1 contacts the touch sensor 92, the touch sensor 92 generates a search signal for the remaining line.

As shown in FIGS. 5 and 6, the remaining line 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 the central shaft 49,
The central shaft 49 is rotatably supported by the machine frame 12 via bearings 51, 51 'and connected to a motor 52 via a coupling rig 54.

The movable pinch roll 50 is slidably mounted on a pair of linear guide rails 56, 56 'rotatably supported by a central shaft 49, and is mounted on a block 60 which moves linearly by a cylinder 58. In addition, the machine frame is installed on the straight guide rails 56 and 56 '.
A piston rod 64a of a cylinder 64 swingably supported at a fulcrum 62 is connected to the piston 12. Therefore, the movable pinch roll 50 can be linearly moved by the cylinder 58 to be engaged with the fixed pinch roll 48 or separated from the fixed pinch roll 48.

Then, the movable pinch roll 50 that engages with the fixed pinch roll 48 by expanding and contracting the piston rod 64a of the cylinder 64 is provided with a central shaft 49 along the outer peripheral surface of the fixed pinch roll 48.
Can be reciprocated around the cutter means 24 side.

As shown in FIG. 6, remaining line guide rollers 66, 66 ', 68 and remaining line guide rods 68' arranged in a cross beam are provided below the remaining line feeding means 22. 66, 66 ', 68
Is fixedly arranged, but the residual wire guide rod 68 'is arranged to be openable and closable with respect to the residual wire guide rollers 66, 66', 68 by a cylinder 70.

The cutter means 24, as shown in FIGS. 7 and 8, has a fixed blade 74 attached to the machine frame 12 via a bracket 72,
The rotary body 75 is rotatably supported by the bracket 72, and includes two rotary blades 76 and 76 'attached to the rotary body 75.
It is connected to a motor 86 on the machine frame 12 via a pulley 80, a belt 82 and a pulley 84 attached to the rotary shaft 78.

Therefore, the residual line portion which has passed between the fixed blade 74 of the cutter means 24 and the rotary blade 76 or 76 'on the rotary body 75 by the residual line feeding means 22 is a rotary blade 76 which rotates by the rotation of the rotary body 75.
Alternatively, it is cut by 76 'and cut off from the following remaining line portion. The rotary blades 76, 76 'are 180 in the illustrated embodiment.
It is attached to the rotating body 75 at intervals, and this rotating body 75 is
Since the motor 86 continuously rotates, the residual wire 1 is sent to the cutter means 24 every half rotation of the rotating body 75.
It can be seen that it is shredded according to the feeding length of. As can be seen from FIG. 1, the cutter means 24 is arranged in the chute 88 to drop the cut scrap wire 1a into the scrap box 90.

Next, the method of the present invention will be described in detail with reference to FIGS. 1 and 2 to 8. The spool 14 is carried on the conveyor 13 and is rotated by a position detection sensor such as a photoelectric switch (not shown). When it is detected that has reached a predetermined position in the residual line processing device 10, the conveyor 13 stops and holds the spool 14 at this predetermined position. At this time, the spindles 16 and 16 'project to rotatably support and position the spool 14 (spool positioning step). As shown in FIG. 1, the end portion 1b of the remaining line 1 has a collar 14 of the spool 14.
It is locked in the hole 14b of a.

Then, the vertical guide mechanism 25 of the clamp means 20 operates to lower the clamp 28 from position A to position B in FIG. 1, and then the horizontal guide mechanism 26 operates to horizontally move from position B to position C.

After that, when the spool 14 rotates and the end of the residual line 1 comes into contact with the touch sensor 92 attached to the clamp 28 and the residual line 1 is searched, the touch sensor 92 generates a residual line search signal. The rotation of the spool 14 is stopped. At this time, the movable jaw 42 'of the clamp 28 is closed by the operation of the cylinder 44 so as to grip the end portion 1b of the remaining line 1 (remaining line holding step).

As described above, when the clamp 28 is moved from the position C to the position B by the horizontal guide mechanism 26 in a state where the end 1b of the residual line 1 is gripped by the clamp 28, the end 1b of the residual line 1 is moved to the collar of the spool 14. Exit through hole 14b in 14a. In addition, the clamp 28
Moves up from the position B to the position A by the operation of the vertical guide mechanism 25. At this time, since the residual wire guide rod 68 ′ located below the residual wire feeding means 22 is open, the residual wire 1 that is lifted together with the clamp 28 while being gripped by the clamp 28 is the residual wire guide rollers 66, 66. After passing through the space between ′ and 68, 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 residual wire feeding means 22 is bitten by the operation of the cylinder 58 so as to sandwich the residual wire 1 and engages with the fixed pinch roll 48 from position D to position E in FIG. To the movable jaw 42 ′ of the clamp 28 at the same time.
Opens the fixed jaw 42 to release the residual wire 1 (an residual wire transfer step). As a result, the residual line 1 is transferred from the clamp 28 to the residual line feeding means 22.

On the other hand, the cylinder 64 of the residual line feeding means 22 operates to block
Since the 60 swings around the fulcrum 62, the movable pinch roll 50
Rotates around the fixed pinch roll 48 and feeds the remaining wire 1 toward the cutter means 24 (remaining wire feeding step).

In the cutter means 24, since the rotating body 75 is rotated by the motor 86, the rotary blade 76 or 76 ', which is closer to the fixed blade 74 in the rotating direction, leaves the residual line 1 on the rotary blades 76 and 76'. Cut off each feeding length until and reach the cutting position (remaining wire shredding step). In this way, the remaining line 1 is cut off by the rotary blades 76 or 76 '.
Since 6'corresponds to the residual wire feed amount until the cutting position is reached, the cut-off length of the residual wire 1 is extremely short,
The remaining line 1 is shredded as shown in FIG.

The large number of scrap wires 1a formed in this way are
Through it and fall into the waste box 90.

When the remaining line 1 on the spool 14 disappears, the spool 14 stops, and upon detection of this, the movable pinch roll 50 returns to the position D, and at the same time, the spindles 16 and 16 'retract to move the spool 14 to the conveyor 13 The spool 14 that has been subjected to the remaining line processing is carried out by the movement on the conveyor 13 by the movement of the conveyor 13, and at the same time, the next spool 14 to be subjected to the remaining line processing is carried into the remaining line processing device 10 and the above operation is repeated.

According to the present invention, as described above, the spool positioning,
The search and grip of the end of the residual line, the transfer of the end of the residual line to the residual line feeding means, the feeding of the residual line to the cutter means, and the shredding of the residual line by the cutter means are automatically continued. It is possible to automate the remaining line processing, so that the worker does not have to wait at the work site, and work safely and efficiently while avoiding the risk of work due to the runaway of the last terminal of the remaining line. be able to.

Further, since the spool is rotatably positioned by the spool positioning means, the spool does not dance while the remaining line is being paid out, and therefore noise is not generated unlike the underroll type paying machine, and the work environment is improved. Is improved,
Further, since the remaining wire is shredded and stored in the waste box as a waste wire, the space factor of the waste box is improved.
