Description

Description: TECHNICAL FIELD The present invention relates to a method of winding a filament on a winding bobbin.

(Prior Art) A filament winding device, which has a traverser and an automatic bobbin transfer device, automatically supplies the winding filament to the winding bobbin, and continuously winds the filament. When winding up to a standard length, the standard-size winding bobbin is discharged to an elevator without cutting the filaments, and instead an empty winding bobbin is wound in the winding section. The wire rod body is moved in and the outer surface of one of the collars of the empty winding bobbin is crossed by the linear body connected to the regular length winding bobbin, and the linear body is pressed against the one collar of the winding bobbin by the line pressing means. And the traverse guide in such a state so as to face one end of the winding drum of the empty winding bobbin (the end of the flange-side winding drum fixing the filament), and the empty winding bobbin. The filament is wound around the winding cylinder of the empty take-up bobbin by rotating. When the winding of the filament on the winding bobbin reaches the standard length, the traverse guide is stopped when the traverse guide returns to the one end side of the winding drum described above, and the winding drive source (wire drawing) It often cooperates with a drive source such as a machine, an annealing machine, an insulation extruder, a twisting machine, etc.) to stop the winding. In addition, the traverser is driven by an independent drive source in a relation that the traverse guide is stopped on one side of the take-up bobbin, so that the inertia is reduced, and the traverse is performed regardless of the rotation due to the inertia of the take-up drive source. The guide stops on one side of the take-up bobbin.

(Problems to be Solved by the Invention) However, in such a method of winding a filament, even if the traverse guide is stopped on one side of the take-up bobbin, the take-up drive source side is inertial for a while. Since the filamentous body is rotated to supply the filamentous body, there is a problem that a hump is formed on the winding drum on one side of the flange of the winding bobbin. If a winding wire is formed on the winding bobbin due to the winding wire body, it may cause a wire breakage during the supply in the subsequent process, so that there is a problem that the unwinding operation is required.

An object of the present invention is to provide a winding method for a filament body that can prevent a hump from occurring even if the traverse guide is stopped on one side of the collar of the winding bobbin to finish the winding of the filament body. Especially.

(Means for Solving the Problems) Means of the present invention for achieving the above object will be described with reference to FIGS. 1 to 3 corresponding to the embodiments. After the winding of the filament 9 reaches a fixed length and the fixed length signal is output from the fixed length signal generating means 13, the time t reaches the time when the traverse guide 8 reaches one of the flanges of the winding bobbin 1 ( (t is the time required from the output of the stop signal for stopping the rotation of the winding bobbin 1 to the stop of the winding bobbin 1) before outputting the stop signal before traversing on one flange side of the winding bobbin 1. The feature is that the guide 8 is stopped and the winding of the filament 9 is also stopped.

(Operation) When the stop signal is issued at such a timing, the traverse guide 8 stops at one brim side of the take-up bobbin 1 and the winding of the linear member 9 also stops, so that a hump cannot be formed.

(Embodiment) The first embodiment of the method for winding a filament according to the present invention will be described below.
A description will be given with reference to FIGS.

In the present embodiment, the inertia of the winding bobbin 1 is small, and the winding bobbin 1 receives a stop signal from the time T required for the traverse guide 8 to move between the collars 2A and 2B of the winding bobbin 1 after the winding signal is output. This is an example when the time t required for the take-up bobbin 1 to stop is short.

In the winding device according to the present embodiment, at the winding position A, the winding bobbin 1 has the drive side cone type bobbin support 3 and the driving side cone type bobbin support 4 inserted into the holes of the collars 2A and 2B. Rotational force from a winding drive source (not shown) is applied to the rotating shaft 6 via the pulley 5 to rotate for winding. On the other hand, the traverser 7 driven by an independent drive source (not shown) moves from one end side to the other end side to the other end side of the winding cylinder 2C of the winding bobbin 1 by the traverse action of the traverse guide 8. The strips 9 are sequentially supplied. To detect the reverse position of the traverse guide 8, the first and second position sensors 11a and 11b, which are limit switches arranged along the traverse shaft 10 that drives the traverse guide 8, are operated by the operator 12 of the traverse shaft 10. Performed by receiving an operation.

When the take-up bobbin 1 at the take-up position A has a fixed length, the fixed-length signal generating means 13 including a proximity switch outputs a fixed-length signal to a sequencer (not shown). After that, the second position sensor 11b is moved to the second position by operating the operator 12 of the traverse shaft 10.
When the position signal is output, that is, when the condition that the standard position signal is first output and then the second position signal is output, a timer (not shown) of the sequencer is turned on.
After the elapse of a predetermined time t ₀ , when the timer times out, the timer which also serves as a stop signal generating means outputs a stop signal and supplies it to the winding drive source. The take-up drive source and the take-up bobbin 1 rotate due to inertia from this point for a time t and stop. Therefore, when the winding bobbin 1 is stopped and after the time is up, the operator 12 of the traverse shaft 10 has passed the position of the first position sensor 11a and operated the traverse guide retreat position sensor 14 adjacent thereto ( That is, the timer time t ₀ of the timer is set so as to be the same as the time when the traverse guide 8 reaches the retracted position on the one brim 2A side of the winding bobbin 1 shown in FIG. That is, the timer time t ₀ is set to t ₀ = (T−t). Here, T is the time required for the traverse guide 8 to move between the collars 2A and 2B of the take-up bobbin 1, and t is the time from when the timer expires and a stop signal is issued until the take-up bobbin 1 stops. It's time. The traverse guide retreat position sensor 14 outputs a stop signal to the drive source of the traverser 7, whereby the traverser 7 having a small inertia is immediately stopped. At this time, the traverse guide 8 stops at the retracted position on the one brim 2A side of the winding bobbin 1. Therefore,
At the same time when the take-up bobbin 1 stops rotating, the traverse guide 8 also stops at the position retracted to the one collar 2A of the take-up bobbin 1. Therefore, the take-up bobbin 1 cannot have a hump at the end of winding.

After that, the bobbin support 4 is retracted by operating the cylinder 15 to lower the standard length winding bobbin 1 at the winding position A onto the support 16, and the inclination is used to move the bobbin support 4 downward from the position shown in FIG. It is placed on the elevator 17 waiting at the same time, and then the elevator 17 is raised to the state shown in FIG. Next, the bobbin supply position B is supplied to the empty winding bobbin 1 at the winding position A using the inclination of the rail 18. The empty take-up bobbin 1 that has reached the take-up position A is clamped by both bobbin supports 3 and 4 when the bobbin support 4 is pushed out by the operation of the cylinder 15, and is ready for winding. Also,
At this time, the linear body 9 connected to the traverse guide 8 from the regular-length winding bobbin 1 crosses the outer surface of one collar 2A of the empty winding bobbin 1 at the winding position A as shown in FIG. In this state, when the bobbin is clamped, the linear member 9 is pressed and fixed to the collar 2A by the wire retainer 19 attached to the bobbin support 3 side. In such a state, the traverser 7 is driven, the traverse guide 8 is traversed to a position facing the winding drum 2C of the empty winding bobbin 1, and the winding drive source is driven to rotate the empty winding bobbin 1. Condition 1 starts winding around the winding drum 2C. In addition, due to the sudden increase in tension at this time, the linear body 9 connected to the standard length winding bobbin 1 on the elevator 17 is cut,
It is completely separated from the winding bobbin 1 at the winding position A.

If the rotation time of the take-up bobbin 1 due to inertia is longer than the movement time from the second position sensor 11b until the operator 12 reaches the traverse guide retracted position sensor 14,
The timer may be turned on when the position sensor 11a detects the position. At that time, the traverser 7 is reversed by the operation of the second position sensor 11b and stopped by detecting the position of the traverse guide retreat position sensor 14.

Further, instead of setting the time t = (T−t) with a timer, a stop signal generating means 20 composed of a limit switch is provided at a predetermined position between the first and second position sensors 11a and 11b, The stop signal generation means 20 may output the stop signal when the operation element 12 is operated.

Further, the fixed length signal generating means 13 may be composed of a scale counter.

As described above, according to the present invention, the timing of outputting the stop signal for stopping the rotation of the winding bobbin is t from the time when the traverse guide reaches one flange of the winding bobbin.
Time (t is the time required from when a stop signal for stopping the rotation of the winding bobbin is output until the winding bobbin is stopped)
However, since the traverse guide is stopped on one side of the take-up bobbin on the one side of the take-up bobbin, the take-up of the wire condition is also stopped, and it is possible to prevent the occurrence of a hump at the end of the take-up. Therefore, according to the present invention, it is possible to prevent the occurrence of a hump regardless of the type of winding in which the traverse guide is stopped at one of the flanges of the winding bobbin to end the winding.
