Abstract

PURPOSE:To calculate a value of turnover timing accurately on the basis of a detection signal of a sensor, a distance between the sensor and a traverser and a travel speed of the traverser by installing each bobbin flange detecting sensor, solidly traveling with the traverser, at both sides of the traverser. CONSTITUTION:Each off sensors 50, 60 detecting a bobbin flange 21 solidly traveling with a traverser 11 is installed at both sides of this traverser 11. When the traverser 11 is moved to the right and the bobbin flange 21 is detected by the sensor 50, the detected signal is inputted into a control means, a left travel time T of the traverser 11 is determined on the basis of a travel speed and a distance L between the traverser 11 and the sensor 50 by this control means. After the elapse of the time T, the traverser 11 is tuned over by the control means. Consequently, a wire rod 40 is guided to the whole barrel of a bobbin 20 without entailing any winding failure, thus automation can be done. At time of right movement, it is controlled by the sensor 60 likewise.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a wire winding device for winding wire onto a bobbin.

[Conventional technology]

Wire rods such as electric wires are supplied to the market in a state where they are wound around bobbins after being subjected to predetermined processing. For example, enameled wires are coated with enamel and then subjected to a process of being wound around bobbins.

FIGS. 4 and 5 show a conventional wire winding device used for this winding. In FIG. 4, the wire 40 is taken up by a take-up capstan 8 of a take-up machine 7, and guided from the capstan 8 to a winding machine 10. The winding machine 10 is equipped with a traverser 11 and a bobbin 20, and the wire 40 is wound onto the bobbin 20 while being guided by the traverser 11. FIG. 5 shows these configurations, in which a bobbin 20 with bobbin flanges 21 and 22 on both sides is rotated by a winding motor 1, and this rotation causes the wire to be wound onto the bobbin 20 while maintaining the tension within a certain range. It will be done. The traverser 11 is screwed onto a helical shaft 12, and when the helical shaft 12 is rotated in the forward and reverse directions by a driving means 13 such as a motor, the traverser 11 reciprocates in the length direction of the bobbin 20 and moves the wire 40. The windings are neatly arranged on bobbin 20.

In such a winding device, the wire 40 is attached to the bobbin collar 2.
1.22, and for this reason, the traverser 11 that guides the wire 40 must be wound within the bobbin collar 21.
22, the direction of movement must be reversed. 14.15 uses bobbin 20 to perform this reversal.
This is a limit switch provided corresponding to the bobbin collar 21.22 of the bobbin collar 21.22, and when the traverser 11 reaches the bobbin collar 21.22, the driving means 13 rotates in the opposite direction and acts so that the traverser 11 moves in the opposite direction. ing.

[Problem to be solved by the invention]

In the conventional device, limit switches 14 and 15 are connected to bobbin 20.
If the traverser 11 is installed with high accuracy, the reversal timing of the traverser 11 will be accurate, and the wire will be properly wound. However, if the set position of the bobbin 20 or the cent position of the mint switch 14.15 is not accurate, or if a shift occurs due to the load force during winding work, the limit switch 14.
15 and the bobbin collars 21 and 22. In such a state, the reversal timing of the traverser is no longer accurate, and the wire is wound in an abnormal state. FIG. 7(a) shows the bobbin 20 wound with a wire rod in the state shown in FIG. On the collar 21 side, a winding valley V is formed due to insufficient winding of the wire.

Also, at the beginning of winding the wire, the mint switch 14.15
Even if the bobbin collars 2 and 22 are set correctly, if the amount of winding of the wire increases and the load from the wire is applied, the bobbin collars 2 and 22 may expand as shown in Fig. 6).

If you want to continue winding in this situation,
As shown in FIG. 7(b), the inner end surface portions of the bobbin collars 21 and 22 are insufficiently wound, resulting in a winding valley .

In order to prevent such winding abnormalities, conventionally, an operator monitors the winding state and adjusts the positional deviation of the limit switch. However, such monitoring and adjustment of positional deviation by a worker is complicated, requires a great deal of effort, and has poor workability.

In order to eliminate such drawbacks, Japanese Patent Application Laid-Open No. 55-706
As shown in Publication No. 65, etc., a device has been proposed in which a limit switch 7 that contacts the flange of the winding drum is provided near the traverser, and the direction of the traverser is reversed when the limit switch detects the flange. There is.

However, according to this device, if the collar diameter changes, the position of the limit switch must be changed, and there is some distance between the limit switch and the traverser, so the reversal timing lacks accuracy. become.

Furthermore, as shown in Japanese Patent Application Laid-Open No. 55-156156, a device has been proposed that changes the reversal timing of the traverser by monitoring the state of misalignment near the collar.
In addition to the reversal sensor of the traverser, a sensor for starting winding state monitoring must also be added, which makes the configuration complicated.

Therefore, the purpose of the present invention is to omit the adjustment work by the operator,
It is an object of the present invention to provide a wire winding device that can automatically monitor the winding state and correct winding abnormalities.

Another object of the present invention is to provide a wire winding device in which accurate reversal timing can be obtained and the structure is not complicated.

[Means to solve the problem]

In order to achieve the above object, the present invention includes the following means.

(1) Driving means A means for reciprocating a traverser that guides the wire rod in the length direction of the bobbin. This driving means includes, for example, a motor and a helical shaft connected to the motor, and is configured to reciprocate the traverser by rotating the motor in forward and reverse directions while the traverser is screwed onto the helical shaft.

(2) Sensor means for detecting the bobbin flange. The sensors move integrally with the movement of the traverser and are provided on both sides of the traverser, and detect the bobbin flange before the traverser reaches the bobbin flange. Then, the detection signal is output to the control means.

(3) Control means A means for controlling the drive means so that the traverser reciprocates between the bobbin flanges. This control is performed by calculating the reversal timing of the movement of the traverser based on the detection signal of the bobbin collar of the sensor and outputting it to the driving means. For this reason, data regarding the moving speed of the traverser and the distance between the traverser and the sensor are input to the control means, and the reversal timing is calculated based on these data.

[Effect]

When one of the sensors detects the bobbin collar due to movement of the traverser, the detection signal is output to the control means, and the control means calculates the time until the traverser reaches the bobbin collar. Then, when this time has elapsed, the control means outputs a reversal command to the drive means to reverse the moving direction of the traverser.

【Example〕

FIG. 1 shows the configuration of an embodiment of the present invention, in which the same elements as those of the conventional device are denoted by the same reference numerals.

That is, the bobbin 20 is attached to the output shaft of the winding motor 1 and rotates in one direction, and the wire 40 is rotated in one direction.
is taken up by a take-up capstan 8 of a take-up machine 7, guided by a traverser 11, and wound onto a bobbin 20. In this case, a torque motor is used as the winding motor 1 to apply a constant tension to the wire 40.

Figure 2 shows a side view of the main parts of Figure 1, and shows the traverser 11.
is screwed onto a helical shaft 12, and this helical shaft 12 is connected to a motor 13.
The traverser 11 moves back and forth between the bobbin flanges 21 and 22 of the bobbin 20 by the forward and reverse rotation of the motor 13, so that the wire 40 is wound over the entire body of the bobbin 20. In such a configuration, the helical shaft 12 and the motor 13 serve as driving means for reciprocating the traverser 11. Sensors 50, 60 are provided on both sides of such a traverser 11.

Each sensor 50.60 is attached to the helical shaft 12 at a constant distance from the traverser 11, and each sensor 50.60 reciprocates integrally with the traverser 11 while maintaining a constant distance from the traverser 11. .

In this embodiment, the sensor 50.60 is a proximity sensor attached to the bobbin 20 and the bobbin collar 21.22 so as to maintain a constant distance therebetween. The sensor 60 on the right side detects the bobbin collar 21 on the left side of the traverser 11.
When the bobbin collar 22 moves to the right, the bobbin collar 22 on the right side is detected. That is, the sensors 50 and 60 are provided ahead of the traverser 11 in the direction of movement, and detect the bobbin collar 21 or 22 before the traverser 11 reaches the bobbin collar 21 or 22. In FIG. 1, 30 is a control means to which bobbin collar detection signals A and B from each sensor 50 and 60 are input, and the reversal timing of the moving direction of the traverser 11 is calculated based on these detection signals. Then, the inverted drive signals C and D are output to the motor 13 to control the reciprocating movement of the traverser 11.

Next, the operation of the above embodiment will be explained based on FIG. This figure shows a case where the traverser 11 is moving to the left, and the sensor 50 on the left side detects the bobbin collar 21 on the left side, and the detection signal A is outputted to the control means 30. Control means 3
0 calculates the leftward movement time T of the traverser 11 based on the input of the detection signal A.

This time T is determined by the moving speed of the traverser and the distance between the sensor 50 and the center of the traverser 11, which is a guide member for the wire 40. If the distance is constant, the movement of the traverser 11 It is uniquely determined by the speed, that is, the rotational speed of the motor 12. Therefore,
As the motor 13, it is preferable to use a pulse motor whose rotational speed can be detected, and even if the motor is other than a pulsed motor, the rotational speed can be detected by being equipped with a rotational speed detection sensor such as an encoder. Any motor that can be used can be used. When the travel time T of the traverser 11 calculated as described above has elapsed, the control means 30 outputs a reversal signal C or D to the motor 13, whereby the motor 13 rotates in the reverse direction, and the traverser 11 is reversed and moved to the right. Moving. Therefore, the movement of the traverser 11 is adjusted according to the position and condition of the bobbin flange, and the wire can be guided throughout the body of the bobbin 20, thereby preventing winding abnormalities. Therefore, there is no need for operator monitoring or sensor adjustment work, and winding can be automated.

Note that when the distance between the sensor 50, 60 and the traverser 11 and the rotational speed of the motor 13 are constant, T is constant, so a timer can be used as the control means 30, and this timer can be used as the sensor 50. The configuration can be simplified by starting the operation from the time when the detection signal from .60 is input.

Further, the sensors 50 and 60 may be replaced by other sensors having the same detection ability as the proximity sensor.

〔Effect of the invention〕

As explained above, the present invention moves the sensor that detects the bobbin flange integrally with the traverser, and calculates and controls the reversal timing of the movement of the traverser based on the detection signal of the sensor. It is possible to automate the reversal process, save labor by eliminating the need for operator monitoring and adjustment, and furthermore, it is possible to obtain accurate reversal timing and to suppress the complexity of the configuration.
