DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for continuously winding a filament which can automatically replace a bobbin, and more particularly to a method for temporarily switching the filament from a full bobbin to an empty bobbin. The present invention relates to a device that is stored in a storage drum.

[0002]

2. Description of the Related Art When a filament is wound on a winding bobbin, even when the winding bobbin is fully wound, supply of the filament may not be stopped halfway. For example, when enamel coating is performed on the supply side, enamel coating is a continuous process,
The striatum supply cannot be stopped halfway.

When the winding bobbin is full, it is necessary to replace the bobbin with an empty bobbin. For this purpose, the rotation of the bobbin is stopped, the full bobbin is replaced with an empty bobbin, and after the replacement, the filament is replaced with an empty bobbin. And restart the rotation. Since the filaments continue to be supplied during the bobbin exchange, an extra filament that cannot be wound on the winding bobbin is generated and is discarded as waste.

In order to eliminate the waste, as shown in FIG. 4, a storage device 43 having a storage drum 42 is interposed between a take-up machine on the supply side and a winding bobbin 41, and temporarily provided. It has been done to store lines. While the full bobbin is being replaced with an empty bobbin, the handle 44 of the wire storage drum 42 is turned by hand, and the continuously supplied filament 45 is wound around the wire storage drum 42 and temporarily stored. After the bobbin is replaced, the cut end of the temporarily stored filament is wound around an empty winding bobbin 41 and wound around the winding bobbin 41 via the storage bobbin 42.

[0005]

However, the prior art using the above wire storage drum has the following problems.

Even when a wire storage drum is used, it is difficult to match the winding and unwinding timings of the wire storage drum because it is manually operated, and therefore the workability is poor. In particular,
In the case of a multi-line line where multiple windings are performed in parallel, it is almost impossible to find out which winding bobbin is full and when to find it and manually store it and replace the bobbin. The generation of striatal debris was inevitable.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a method of continuously winding a striated body in which a plurality of bobbins can be automatically exchanged without generating striated chips. Is to provide.

It is another object of the present invention to provide a wire body that enables automatic switching of bobbins with relatively simple equipment and that can easily set the timing of the winding speed and the unwinding speed of the storage drum. To provide a continuous winding device.

[0009]

SUMMARY OF THE INVENTION A continuous winding method for a filament according to the present invention comprises a plurality of winding bobbins for winding a plurality of filaments continuously supplied from a filament supply unit. In the method in which the wound bobbin is replaced with an empty bobbin to continuously wind the striatum, when a full bobbin occurs, the movable carriage is moved near the full bobbin to continuously supply the full bobbin. The striated body is cut and transferred from the full bobbin to the storage drum on the bogie, and the storage drum is rotated in synchronization with the supply speed of the striated body, and the striated body is wound and stored. the full package bobbins in貯線replaced with the empty bobbin, to bind the cut end of貯線striatal the貯線drum after the exchange the empty bobbin, 2 feed rate of the striatum while continuing the貯線taken up by the empty bobbin unwinding the striatum was貯線to貯線drum rotates in the reverse direction the貯線drum to 3 times faster Once the remaining striatum is 貯線 in 貯線 drum reaches a predetermined amount, it is obtained as wound directly winding bobbin transferred to the bobbin striatum from 貯線 drum.

[0010] A continuous winding device for a filament according to the present invention comprises a filament supplying section having a plurality of take-up machines for continuously supplying a plurality of filaments, and each filament supplied from the filament supplying section. And a winding machine having a plurality of winding bobbins for winding the striatum from each dancer pulley, and running along the plurality of winding bobbins to generate a full bobbin. Then at least one stop near the full bobbin
When a full bobbin is generated, the linear body continuously supplied to the full bobbin is cut and transferred from the full bobbin to a storage drum on the bogie, and the linear filament is provided on the mobile bogie. At the time of unwinding of the body, the cut end of the striated body stored in the storage drum is connected to an empty bobbin, and when the remaining striated body stored in the storage drum reaches a predetermined amount, the striated body is removed. And a striated body processing device for transferring from the wire storage drum to the winding bobbin.

Further, provided on a movable carriage, the rotation of which is controlled by a driving device, and the linear body transferred from the full bobbin during normal rotation is wound up to temporarily store the linear body. A storage drum that unwinds the filament to the empty bobbin after replacement while continuing to wind the filament for storage during rotation, and a position detector that detects a dancer displacement of the dancer pulley, A speed detector that detects the rotation speed of the take-up machine, an optical transmission device that sends a dancer displacement signal and a take-up machine speed signal to the movable cart, and a dancer displacement signal and a take-up machine speed signal sent from the optical transmission device. The driving device is controlled on the basis of the above, the rotation speed of the storage drum is synchronized with the rotation speed of the take-up machine when winding to the storage drum, and the rotation speed of the storage drum when unwinding from the storage drum. Is set to 2-3 times the rotation speed of the take-up machine. It is obtained by a roller.

[0012]

When a full bobbin is generated, the mobile trolley travels and stops near the full bobbin. After stopping, the striated body processing device on the movable trolley operates to hold and cut the striated body continuously supplied to the full bobbin, and to couple the cut end to the wire storage drum on the trolley. Moves the striatum from the full bobbin to the wire storage drum.

After the striated body is transferred to the storage drum, the storage device starts to rotate forward by the drive of the driving device, and the striated body continuously supplied from the striated body supply unit is stored in place of the winding bobbin. It is wound up on a wire drum and stored. During this storage, the winding machine operates to replace the full bobbin with an empty bobbin.

After exchanging the bobbin, the striated body processing device is operated again to connect the cut end of the striated body stored in the storage drum to the empty bobbin. Then, as the empty bobbin rotates, the wire storage drum reversely rotates at a speed of two to three times the feed speed of the wire, and the wire stored in the wire storage drum is unwound to the empty bobbin. Begins to be wound up. Here, the wire storage drum has a function of performing the winding operation and the unwinding operation in parallel, so that the wire storage of the wire storage drum is continuously performed at the time of unwinding. Therefore, before the transition of the filament, the filament is wound on the winding bobbin via the wire storage drum.

When the remaining wire stored in the wire storage drum reaches a predetermined amount by the winding on the winding bobbin, the wire processing device is operated and the wire is wound around the wire storage drum. The remaining striated body is removed and transferred to the winding bobbin, and is wound directly on the winding bobbin without passing through the wire storage drum.

Even if the full bobbin is stopped when the bobbin is replaced in this way, the striated body is temporarily stored in the storage drum on the moving bogie, and the stored wire is stored in the bobbin after replacement. Since it is automatically transferred, continuous winding of the striated body on a plurality of winding bobbins becomes possible.

[0017]

Embodiments of the present invention will be described below. FIG. 1 is a schematic configuration diagram in which a continuous winding device for a filament according to the present invention is applied to an automatic bobbin changing device having a plurality of single-axis winding bobbins for respectively winding a plurality of enamel-coated filaments.

This device is composed of a fixed system and a movable system.
The fixed system is arranged in a line in which a filament supply unit 3 having a take-off machine 2 for continuously supplying the enamel-coated filament 1 and a filament 1 supplied from the filament supply unit 3 are wound up. And a winding machine 5 having a plurality of single-axis winding bobbins 4. Although not shown in the figure, each winding bobbin 4
A take-up machine 2 is provided for each. The movable system includes a movable carriage 6 traveling along a plurality of winding bobbins 4, a storage drum 7 provided on the movable carriage 6 for temporarily storing the striatum 1, and a bobbin for automatic exchange. It is mainly composed of a striatum processing device 8 for performing necessary striatum processing.

In the state shown in the figure, after the filament 1 supplied from the take-up machine 2 is transferred from the full bobbin to the wire storage drum 7 on the moving carriage 6, the filament 1 temporarily stored is This shows a state in which the wire is unwound onto the empty bobbin 4 after the replacement while continuing the storage.

In addition to the traverse pulley 9, a dancer pulley 10 for adjusting the tension of the filament 1 supplied from the puller 2 is provided on the path from the puller 2 to the wire storage drum 7. The dancer pulley 10 is used for the linear body 1 from the take-up machine 2.
The position changes in accordance with the difference between the supply speed and the winding speed (rotation speed) of the wire storage drum 7 on the movable carriage 6. During normal winding, the filament 1 from the dancer pulley 10
It is wound directly on the winding bobbin 4 without passing through the wire storage drum 7.

A movable bogie 6 traveling along a plurality of winding bobbins 4 generates a full winding bobbin 4 among a plurality of winding bobbins 4 winding a plurality of filaments 1 in parallel. Then, it is controlled to stop near the full bobbin. In the present embodiment, one moving carriage 6 is provided for 16 winding bobbins, but two or more moving bogies may be provided.

When a full bobbin occurs, the striated body processing device 8 provided on the movable carriage 6 holds and cuts the striated body 1 continuously supplied thereto, and cuts the cut end of the striated body 1. The bobbin is transferred from the full bobbin to the storage drum 7 on the bogie 6 and joined. After the bobbin replacement, the striated body 1 stored in the storage drum 7
Is connected to an empty winding bobbin 4 so that the filament 1 can be wound around the winding bobbin 4 via the wire storage drum 7. Then, when the remaining wire 1 stored in the wire storage drum 7 has been wound for one turn, the wire 1 is removed from the wire storage drum 7 and transferred to the winding bobbin 4 and wound directly from the dancer pulley 10. Wind it up on bobbin 4.

A wire storage drum 7 provided on a movable carriage 6
Is controlled by the drive device 11 to take up the striated body 1 transferred from the full bobbin at the time of forward rotation to the storage drum 7 for storing the wire, and to continue the winding at the time of reverse rotation,
Unwinding of the storage wire is performed on the empty bobbin 4 after the replacement. For this purpose, the wire storage drum 7 includes a winding unit 12 for winding the filament 1 supplied from the winding machine 2, an unwinding unit 13 for feeding the filament 1 to the winding bobbin 4, and a winding unit. And a guide member 15 having a return pulley 14 for guiding the striated body 1 from 12 to the unwinding portion 13, and these rotate with the following correlation with each other. That is, the guide member 15 is directly driven and rotated by the drive device 11, and the winding unit 12 and the unwinding unit 13 rotate forward together with the guide member 15 at the time of winding, and the winding unit 12 at the time of unwinding.
Is rotated forward in accordance with the supply speed of the striated body 1, but the unwinding section 13 is rotated reversely together with the guide member 15.

When the winding operation is performed by the wire storage drum 7, the rotation speeds of the take-up machine 2 and the wire storage drum 7 must be synchronized. Therefore, a position detector 17 composed of, for example, a potentiometer for detecting the displacement of the dancer in conjunction therewith is attached to the dancer pulley 10. This position detector 17
Functions only during the winding operation of the wire storage drum 7. The take-up machine 2 is provided with a speed detector 16 for detecting the rotation speed, for example, a rotary encoder.

The take-off machine speed signal A from the speed detector 16
Is the frequency at which the pulse signal is converted to an analog voltage,
After being converted into a voltage through the voltage converter 18, the voltage is applied to the analog / digital converter 19 together with the dancer displacement signal B from the position detector 17, and the digital serial signal C
Is converted to The digital serial signal C is transmitted to the optical transmission device 2
0 is input to the transmitting device 20a attached to the fixed system constituting the fixed system, and is transmitted to the receiving device 20b attached to the mobile trolley 6 therefrom. Since optical transmission is performed without using a cable, it is possible to eliminate the influence of noise due to cable transmission, deterioration of the cable, and complicated equipment.

The digital serial signal C sent from the fixed system to the movable carriage 6 is returned to the take-up machine speed signal A and the dancer displacement signal B by the digital / analog converter 21 again. Both signals are applied to a speed controller 22, and based on both signals, the speed controller
1 is controlled to accelerate or decelerate the rotation speed of the wire storage drum 7 as follows.

When the wire 1 is wound around the wire storage drum 7 for storing the wire, the winding speed of the wire storage drum 7 is synchronized with the rotation speed of the take-up machine 2. The relationship between the storage drum 7 and the rotation speed of the take-up machine 2 at the dancer roller position is as follows: When the position of the dancer roller is 0, the storage drum rotation speed = the take-up machine rotation speed When the dancer roller moves upward, the storage drum rotation speed <The take-up machine rotation speed When the dancer roller moves downward, the storage drum rotation speed> the take-up machine rotation speed. Therefore, if the rotation speed of the storage drum 7 is corrected by the speed controller 22 according to the position of the dancer pulley 10,
The constant tension winding is performed under the tuning control.

Further, the stored filament 1 is stored in a storage drum 7.
When unwinding from the wire, the take-up machine speed signal A sent from the fixed system is multiplied by 2 to 3 by the speed controller 22 to obtain the rotation speed of the wire storage drum 7, and the unwinding operation of the filament 1 is performed. Do. Here, the unwinding speed is represented by a take-up machine speed signal A.
It is too long to transfer the striated body 1 from the wire storage drum 7 to the winding bobbin 4 if it is less than 2 times if it is less than 2 times. This is to prevent the winding bobbin 4 from becoming loose due to insufficient torque of the winding bobbin 4 when the filament 1 is transferred to the winding bobbin 4.

Now, the operation of the automatic bobbin changing device having the above-described configuration will be described with reference to FIG.

After the enamel coating, it is assumed that a full bobbin 4a is generated in one of the plurality of winding bobbins 4 winding the filament 1 continuously supplied from the take-up machine (FIG. 2).
(A)). Then, the mobile trolley 6 travels to the place where the full bobbin 4a is located and stops (FIG. 2B). The striated body processing device 8 installed on the trolley 6 is operated to automatically hold and cut the striated body 1, and the cut end is transferred to the wire storage drum 4 on the trolley 6 for connection (FIG. 2 (c)). The full bobbin 4 is stopped, and at the same time, the wire storage drum 4 is rotated forward to start the wire storage of the striatum 1. At this time, the rotation speed of the wire storage drum 7 is controlled by the
(FIG. 2D).

The full bobbin 4a is replaced with an empty bobbin 4b during the storing of the wire storing drum 7 (FIG. 2 (e)). This exchange is automatically performed by the winding machine 5. Unlike manual replacement, workability is improved by automating bobbin replacement, and replacement of a full bobbin, which is a heavy object, does not take much time and transportation can be performed safely.

After the bobbin is replaced, the striated body processing device 8 on the trolley 6 is moved, and the cut end of the striated body 1 wound from the winding section 12 to the unwinding section 13 via the return pulley 14 is cut into an empty bobbin. 4b, and rotates the empty bobbin 4a. Simultaneously with this rotation, the wire storage drum 7 is rotated in reverse (FIG. 2 (f)).
At this time, by setting the reverse rotation speed to be equal to or higher than the rotation speed of the take-up unit, the unwinding unit 1 can continue to store the wire in the winding unit 12.
The wire body 1 stored in the wire 3 can be quickly wound around the winding bobbin 4 (FIG. 2 (g)). When the striated body 1 of the winding unit 12 and the unwinding unit 13 has the remaining number of turns, the striated body 1 is removed from the wire storage drum 7 by the striated body processing device 8 installed on the carriage 6. The linear body 1 is transferred from the take-up machine 2 directly to the winding bobbin 4 without passing through the winding drum 7 to the winding bobbin 4.
Is wound up (FIG. 2 (h)).

From the start of the winding operation for starting the storage of FIG. 2D, the number of forward rotations of the storage drum 7 is counted by the rotation counter 23, and the unwinding to start the unwinding of FIG. When the counting result is subtracted from the operation start point and the remaining number becomes 1, a command is sent to the striatum processing device 8 to move the striatum 1 from the wire storage drum 7 to the winding bobbin 4. . When rotating the wire storage drum 7 from the forward rotation to the reverse rotation, as shown in FIG.
A method is adopted in which the speed is gradually decelerated from the forward rotation, temporarily stopped, and gradually accelerated even when the reverse rotation is started. The reason why the slow start and the slow down are performed at the time of the forward rotation / reverse rotation switching as described above is that when the rapid forward / reverse rotation switching is performed,
This is to prevent a situation in which the rotation of the winding bobbin 4 cannot keep up with the rotation of the winding bobbin 4 so as to cause a so-called line thickening, biting, line skipping, or the like, so that the winding cannot be rewound.

As described above, according to the present embodiment, when the striated body is wound in parallel on a plurality of winding bobbins, and when any of the winding bobbins reaches a full winding state, the movable carriage moves. hand,
The wire is automatically stored in the striated body, and after the bobbin is replaced, the striated body stored in the replaced empty bobbin is automatically unwound. This is extremely effective for automatically changing the winding bobbin of the hanging line, and continuous automatic winding can be realized.

[0035]

According to the method of the present invention, when the bobbin is exchanged, the movable carriage is moved to store the filament in the storage drum in synchronization with the supply speed of the filament, and the filament is supplied after replacement. 2-3 of speed
Since twice as fast and as wound on the empty bobbin, without Rukoto generate striatal debris can be done automatically the bobbin exchange, the striatum in succession to a plurality of winding bobbins Can be wound up.

[0036]

The number of revolutions of the wire storage drum is counted, and is counted positively during winding, and negatively counted during unwinding,
If the filament is moved from the storage drum to the take-up bobbin when the grand total becomes plus 1, the transfer of the filament from the storage drum to the take-up bobbin can be performed smoothly. it can.

According to the apparatus of the present invention, since the moving carriage is moved to automatically switch the striated body from the full bobbin to the empty bobbin, a plurality of bobbins can be exchanged automatically. . In addition, since the devices necessary for switching the striated bodies are integrated on the movable trolley, the equipment can be simplified. Furthermore, since the rotation speed of the wire storage drum is controlled based on the speed of the wire take-up machine that continuously supplies the striated body and the dancer displacement of the dancer pulley, the rotation speed of the wire take-up machine and the storage drum that are difficult to timing are controlled. The timing of the winding speed can be synchronized.

A rotary counter for counting the number of forward and reverse rotations of the wire storage drum is provided, and when the total becomes plus 1, the wire is wound from the rotary counter to the wire body processing device from the wire storage drum. When a command to move to the take-up bobbin is given, the transfer of the umbilical member from the wire storage drum to the take-up bobbin can be performed smoothly.
