Abstract

PURPOSE:To orderly wind up into a barrel-shaped section by finely controlling the distance of traverse via a screw shaft based on the number of times at which the switch of a stopper unit is brought into contact with a traverse unit. CONSTITUTION:The traverse pitch speed of a traverse unit 3 is controlled by a motor 5 for rotating a bobbin 6, an encoder 15, a detector 16, and a motor 12 which is synchronously rotated via a controller 18. Also, the number of times at which the traverse unit 3 is brought into contact with a switch 19 provided on one stopper unit 11' of stopper units 11, 11' is counted by a counter 21 and, based on this, a stepping motor 22 is driven moving the stopper units 11, 11' by means of a screw shaft 9, to finely control the distance of traverse of the traverse unit 3. Thereby, a wire material can be orderly wound up around a bobbin having no collar part, in a barrel-shaped section.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention is an apparatus for winding a wire onto the bobbin by rotating a winding grain bin, guiding the wire by a reciprocating traverse unit, and winding the wire onto the bobbin. Regarding the wire winding force device that can correctly wind the wire without making the winding arrangement irregular, it is especially adopted for winding the wire onto the so-called open reel winding bobbin, which has a tapered brim. It is suitable for this purpose.

[Conventional technology]

Conventionally known winding devices of this type include a first detection means for detecting the rotational speed of the bobbin, and a second detection means for detecting the linear velocity, as seen in Japanese Patent Laid-Open No. 59-22858, for example. a detection means, a calculation unit that calculates a target value change in the stroke width of the traverser from the detection results of the first and second detection means, and a drive that detects the stroke position of the traverser and allows the detected stroke position to be changed. and a correction unit for driving the detector in accordance with the target change calculated by the calculation unit, and a correction unit for driving the detector in accordance with the target change calculated by the calculation unit, and adjusting the stroke width of the traverser in relation to the detection signal from the detector. There is something to control.

[Problem that the invention seeks to solve]

Even in this conventional improved winding device, the actual linear speed due to the slip between the capstan and the wire rod, which determines the winding speed, is slightly affected by this error, and the traverse movement is controlled by a micro switch, proximity switch or photoelectric switch. Even if the winding is detected by a detector such as the above, as the winding speed increases, an error occurs in signal generation, and the cumulative error causes irregularities in the winding arrangement on the collar surface. That is, when the distance between the two ribs has a small amount of traverse movement, the wire 32 is wound onto the bobbin 31 with a convex cross section in what is called a thick wave winding, as shown in FIG. At that time, the same figure (b
), a phenomenon occurs in which the material is wound into a so-called wave winding with a concave cross section. Such a winding configuration causes spring slippage of the wire rod, and when the wire rod is taken out from the reel at high speed, the wires become entangled with each other, causing wire breakage.

In addition, because conventional winding devices use a CPU to process signals between the detector and the correction motor, the system inevitably becomes large, the bobbin shape changes, and unforeseen problems occur. When an accident occurs, we are unable to respond quickly,
Operational errors were also prone to occur.

[Means for solving problems]

The present invention solves the problems caused by the conventional device described above.
The configuration will be explained below based on the drawings.

FIG. 1 is a front view of the apparatus of the present invention, in which a wire rod 1 is fed out at a constant speed from a capstan 2, guided by a guide pulley 4 of a traverse unit 3, and placed on a take-up grain bin 6 which is rotationally driven by a torque motor 5. rolled around. traverse·
The unit 3 is mounted to move in the traverse direction on a rolling shaft 8 attached to a )7 perspective unit support 7. A screw shaft 9 and a support shaft 10 are supported on the traverse unit support base 7 in a positional relationship parallel to the rolling shaft 8, and on both sides there are stopper units 11, 111 is installed. The traverse unit 3, which moves on the east side of the rolling shaft by the rotational drive of the speed control motor 12, moves every time the advancing direction switching lever 15 attached to its lower end comes into contact with the stoppers 14 and 14' of both stopper units. 1. The traveling direction is configured to be switched.

At the shaft end of the torque motor 5 that drives the take-up grain bin, there is a
An encoder 15 is attached. When the encoder 15 rotates, a corresponding amount of pulse signal is generated in the detector 16, converted into a signal by the converter 17, and sent to the controller 18. The controller 18 sends sufficient power to the speed control motor 12 to determine the number of rotations of the speed control motor 12. In this way, the torque motor 5 and the speed control motor 12 are synchronized. Since the rolling shaft 8 and the speed control motor 12 are connected by a coupling, their rotational speeds match, and the traverse unit 3 moves on the rolling shaft 8 at a speed commensurate with the rotational speed of the four-ring shaft 8. move.

The threaded shaft 9 has stopper units 11 and 11' on both sides for regulating the reciprocating movement of the traverse unit 3.
They are joined with 7 langes in the center, and threads are cut symmetrically from the center of the 7-rank part. That is, two symmetrically threaded shafts are connected at the center to form a coupling machine #119, and when the threaded shaft 9 rotates,
A stopper unit 11.11' containing a corresponding nut mechanism is configured to move by an amount commensurate with the amount of rotation thereof. Specifically, the contact between the switch 2o provided on the stopper and the traverse unit 3 is detected by the counter 21, and when a predetermined count is reached, a pulse output signal command is sent to the oscillator 22, and the stepping motor 23 is activated as required. The screw shaft 9 rotates and the stopper unit 11.11' moves in a predetermined direction by the required amount.

In this way, taking an open reel as an example, both stopper units move outward from time to time along the shape of the brim, and the traverse distance is controlled while the wire is neatly placed on the take-up grain bin. It is something that can be wound up.

[Action/effect of the invention]

According to the wire winding device of the present invention having the above configuration,
While the traverse pitch speed is controlled by the motor 12 that rotates in synchronization with the motor 5 that rotationally drives the bobbin,
A switch 19 provided on the stopper unit switches the traverse
The traverse distance is finely controlled by the action of the stepping motor 22, which is driven based on the number of times it has come into contact with the unit (5), and the screw shaft 9, which is rotated by the stepping motor 22, which causes irregularities in the winding arrangement as in the case of conventional bags. There's nothing to do. Moreover, the traverse pitch speed control and the traverse distance control can be performed independently, and there is no need to program it in advance like in conventional CPU-based counting processing devices, so the system does not become large and unexpected Accidents and configuration errors can be handled without stopping the entire system.

Also, even if the shape changes to a winding bobbin where one side of the brim is tapered and the other side is perpendicular to the winding drum as shown in the second figure, if the connecting rod of coupling 2G is removed, the left and right sides will become independent. By driving the screw shaft 9, it is possible to respond quickly. Furthermore, by reversing the screw shaft 9, both stopper units 11,
If the angle of 11° is moved inward from time to time, the bobbin 3 without a flange can be formed, for example, as shown in FIG.
It is also possible to orderly wind the wire rod 32 on the wire rod 1 in a drum-shaped cross section.

(3) Detailed Description of the Invention [Field of Industrial Application] The present invention provides an apparatus for winding the wire onto the bobbin by rotating a winding warp bin, guiding the wire by a reciprocating traverse unit, and winding the wire onto the bobbin. Regarding the wire winding device that can correctly wind the wire without irregular winding arrangement, it is especially adopted for winding the wire onto a so-called open reel winding bobbin with a tapered brim. It is suitable for this purpose. [Prior Art] A conventionally known winding υ device of this type includes a 1' detection means for detecting the rotational speed of the bobbin, and a wire 1g2 detection means for detecting the speed; a calculation unit for calculating a target value change in the stroke width of the traverser from the detection results by the first and second detection means; and a stroke position for detecting the stroke position of the traverser. and a correction unit for driving the detector in accordance with the target change computed by the arithmetic unit, the detector being driven in a manner that is variable in relation to the detection signal from the detector. There is a device that controls the stroke width of the traverser. [Problems to be Solved by the Invention] Even in this conventional improved winding device, the actual linear speed is slightly influenced by this error due to slip between the capstan and the wire rod, which determines the winding speed. Even if the amount of traverse movement is detected by a detector such as a micro switch, proximity switch, or photoelectric switch, an error occurs in signal generation as the winding speed increases, and the cumulative error causes irregularities in the winding arrangement on the collar surface. do. That is, when the amount of traverse movement between the ribs is small, the wire 52 is wound onto the bobbin 31 with a convex cross section in what is called a thick wave winding, as shown in FIG. At that time, the same figure (b
) As shown in K, a phenomenon occurs in which the material is wound into a so-called wave winding with a concave cross section. Such a winding configuration causes spring slippage of the wire rod, and when the wire rod is taken out from the reel at high speed, the wires become entangled with each other, causing wire breakage. In addition, since conventional winding devices use a CPU to process signals between the detector and the correction motor, the system is inevitably large and the front and bobbin shapes have to be changed, and unexpected problems occur. If an accident occurs, we cannot respond quickly,
Operational errors were also likely to occur. [Means for solving the problems] The present invention solves the problems caused by the above-mentioned conventional device.

A shaft end K of the torque motor 5 that drives the take-up grain bin. An encoder 1''5 is attached. When the encoder 15 rotates, a corresponding amount of pulse signal is generated in the detector 16, converted into a signal by a converter 17, and sent to the controller 18. The controller 18 sends sufficient power to the speed control motor 12 to determine the rotational speed of the speed control motor 12. In this way, the torque motor 5 and the speed controller a)

The traverse unit 3 moves on the rolling shaft 8 at a speed commensurate with the number of rotations of the rolling shaft 8. The threaded shaft 9 has stopper units 11 and 11' on both sides for regulating the reciprocating movement of the traverse unit 3.
They are joined at the center with 7 langes, and threads are cut symmetrically from the center of the flange. That is, two symmetrically threaded shafts are connected at the center to form a coupling mechanism 20, and the threaded shaft 9 rotates. FIG. 2 shows another example of a screw shaft coupling mechanism, in which the screw shaft 9 is separated at the center of the shaft, and a bevel gear 2 is placed opposite the ends of both separated shafts.

Specifically, the contact between the switch 19 provided in the stopper unit 7) and the traverse unit 3 is received by the counter 21, and when a predetermined count is reached, a pulse output signal command is sent to the overlooker 22, which requires the stepping motor 25. The screw shaft 9 rotates and the stopper unit 11.11' moves by the required amount in a predetermined direction.

The traverse distance is finely controlled by the action of the stepping motor 25, which is driven based on the number of times the unit 3 is in contact with the unit 3, and the screw shaft 90, which is rotated by the stepping motor 25, so there is no possibility of irregularities in the winding arrangement as in conventional devices. . Furthermore, the traverse pitch speed and the traverse distance can be controlled independently, which makes it possible to control the traverse pitch speed and traverse distance independently.
Since there is no need for programming in advance, unlike devices that perform counting processing using a PU, the system does not become large, and unexpected accidents or setting errors can be dealt with without stopping the entire system. -! 9.
