Abstract

PROBLEM TO BE SOLVED: To reduce dispersion of wound wire length, prevent worsening of a wound shape and reduce a wasteful wire at the time of wind switching a traveling wire from one bobbin of an electric wire winder to the other empty bobbin. SOLUTION: After the start of line operation of an electric wire winder, each operation equipment for operating a wind switching device is put in dummy wind switching action a plurality of times, and optimum timing of each operating equipment converted into the predetermined counting pulse number in length is set to perform electric wire production operation. The actual operating time of wind switching action during production operation is clocked, and the obtained actual operating time data is converted into the counting pulse number corresponding to the production speed of the electric wire to obtain actual start timing of each operating equipment. A discrepancy between the obtained actual start timing and the optimum start timing is obtained as the difference of the counting pulse number, and the start timing of each operating equipment is set again so that the obtained difference of the counting pulse number becomes zero.

2. Description of the Related Art A typical conventional wire winding machine for continuously winding coated wires sent from a wire coating device is, for example, a schematic side view of FIG. FIG. 5B is a schematic plan view thereof (these figures show a state in which an electric wire is wound from a bobbin in a fully wound state to an empty bobbin side). . Hereinafter, the configuration of the electric wire winder will be described with reference to FIGS. 5A and 5B. The electric wire winder includes a traveling line 9 which is an electric wire covered by an electric wire coating device (not shown). Are continuously wound up. The traveling line 9 sent out from the electric wire covering device is wound around the bobbin 1 on the right side in FIG. 1 via the traverser 6 reciprocated in the longitudinal direction of the rotating shaft 8 rotated forward and reverse by the servomotor 7. ing. The bobbin 1 has a claw 1b for cutting the traveling line 9 when rewinding from the bobbin 2 to the bobbin 1. The bobbin 2 has a claw 1b from the bobbin 1.
Claws 2b for cutting the traveling line 9 when rewinding are provided.

Further, the auxiliary line shifting operation cylinder 3a is removably moved in the direction of the bobbin 1 to a position outside the claw flange 1a having the claw 1b of the bobbin 1.
Covered travel line 9 sent via traverser 6
Travel line 9 so that the claw 1b is not caught by the claw 1b.
An auxiliary line shifter 3 that is pushed in a direction away from b is provided. An auxiliary line shifter 3 is also provided on the bobbin 2 side, but is omitted in the figure because of the same configuration.

On the side of the bobbin 1 opposite to the auxiliary line shifter 3,
In order to prevent the end of the wire wound on the full bobbin 1 after rewinding from damaging the bobbin 1, the main cover operating cylinder 4 a is slidably moved in the direction of the auxiliary line shifter 3 in the direction of the auxiliary line shifter 3. And a main cover 4 for preventing the terminal from jumping out. Further, the traveling line 9 is moved from the bobbin 1 to the bobbin 2
Conversely, when rewinding from bobbin 2 to bobbin 1, it is operated by main line shifting operation cylinder 5a and cuts running line 9 by claw 1b or 2b. A main line shifter 5 is provided for drawing to a contact position. Of course, on the bobbin 2 side,
Like the auxiliary line shifter 3, a main cover for preventing the terminal from jumping out is provided, but is omitted from the drawing because of the same configuration. The rewinding device includes the auxiliary line shifter 3, the main cover 4, and the main line shifter 5. The auxiliary line shifter operating cylinder 3a, the main cover operating cylinder 4a, and the main line shifter operating cylinder 5a operate the rewinding device. Each operating device to be performed.

Next, a description will be given of a case where the electric wire winding machine having such a configuration continuously winds and rewinds the electric wire covered by the electric wire coating device. For example, when it is detected that the winding length of the electric wire wound on the bobbin 1 has become the "forecast length", it is set to be emitted when a predetermined time comes before the winding length. Bobbin 2 which is an empty bobbin for rewinding
Is started, and is rotated at a constant peripheral speed. However, when winding is started, the winding is thickened, and the operation is shifted to an operation in which the rotation speed gradually becomes lower (hereinafter, referred to as a slack operation).
On the other hand, the bobbin 1 is running slack because it is thick. The predetermined time is set based on a time required from when a motor (not shown) for driving the bobbin 2 which is an empty bobbin is started to when the bobbin 2 rotates at a constant peripheral speed.

When the winding length of the wire reaches a preset "full length", the following rewinding operation is started. That is, when the winding length reaches the preset “full length”, the traverser 6 is moved to the claw flange 2 a side of the bobbin 2. When it is confirmed that the traverser 6 has moved to the claw flange 2a side, the auxiliary line shifter 3 and the main cover 4 on the bobbin 1 side are aligned with a white arrow pointing downward and a black arrow pointing upward in FIG. As shown by the arrows, the traveling line 9 is moved in the opposite direction, and after the completion of the movement of the main cover 4 and the auxiliary line shifter 3, the traveling line 9 is drawn toward the claw flange 2 a by the main line shifter 5. Then, the traveling line 9 is hooked and cut by the claw 2b of the bobbin 2 and the bobbin 2
And the end of the wire on the bobbin 1 side is wound into the main cover 4 on the bobbin 1 side.

[0007]

By the way, an air cylinder is generally employed because the operating device of the winding device for winding a wire is inexpensive and its structure can be simplified. For this reason, the operation time varies due to a change in sliding resistance and the like, and the winding wire length for each bobbin tends to vary. That is, the sliding resistance of the air cylinder changes greatly at the time of the first operation after a break and the surrounding environment. Further, for example, when the traverser moves ahead, it is necessary to stop the movement of the traverser until the main cover moves to a predetermined position, and to wait until the main line can be moved. If the waiting time of the traverser is long, the wire will be wound at one place of the winding bobbin, so the winding shape will be worse and the secondary process will have adverse effects such as wire elongation and disconnection. Absent.

[0008] When the winding wire length varies,
Since the length is set to the relatively safe side, the yield is consequently reduced. In order to reduce the variation in the winding wire length for each bobbin, it is conceivable to correct the variation in the operation time of the main cover and the approaching of the main line by predicting a load variation or the like. However, since the total fluctuation time of these operations is large, the required correction amount becomes large, and a problem such as a shortage of the required length occurs at the time of over-correction. .

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reduce the variation in the winding wire length, prevent the winding shape from deteriorating, and reduce the useless wires. It is an object of the present invention to provide a switching control method and an electric wire rewinding control device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electric wire rewinding control device for controlling a rewinding device of an electric wire winder according to an embodiment of the present invention will be described.
FIG. 1 of a schematic configuration explanatory view (however, a bobbin, an auxiliary line shifter, a main cover, and the like are omitted), FIG. 2 of a flowchart showing a method of controlling a simulated rewinding operation, and a production rewinding operation With reference to FIG. 3 of a flowchart showing the control method, the same and the same functions as those of the conventional electric wire winder will be described with the same names and reference numerals. However, since the configuration of the electric wire winder itself is exactly the same as that of the conventional example, the same components are denoted by the same reference numerals and the description of the configuration of the electric wire winder is omitted.

First, the configuration of an electric wire rewinding control device 10 of a rewinding device for an electric wire winder according to an embodiment of the present invention will be described with reference to FIG. A limit switch 11 ₃ which is a position detector for measuring the operation time of the auxiliary line shifting operation cylinder 3a for operating the auxiliary line shifting device, and a limit switch 11 for measuring the operation time of the main cover operation cylinder 4a which operates the main cover. _4. Limit switch 11 ₅ for measuring the operation time of the main line shift operation cylinder 5a for operating the main line shifter ₅ ,
And the limit switch 11 ₆ for measuring the operating time of the traverser 6 is provided. The position of each operating device measured by the limit switch 11 is input to a controller 12 described later as a position signal. Each of the position signals of the operating devices output from each of the limit switches 11 is an operation start position signal and an operation end position signal.

The controller 12 has a function of determining the operating time of each operating device based on the position signal input from each of the limit switches 11. The controller 12 further includes a predetermined measuring pulse. Is entered. Then, the controller 12 obtains a simulated operation time in the simulated rewinding operation of each operating device after the operation of the electric wire winder is started, and converts the simulated operation time into a measured pulse number based on the measured pulse. It is provided with a function of obtaining the initial start timing of each operating device by conversion and presetting the obtained initial start timing. Also, this controller 1
2 includes a pulse generator 1 driven by a capstan (not shown) provided on the supply base side of the traveling line 9 with respect to the traverser 6 during the actual rewinding operation of each operating device.
An output pulse based on the production speed of the electric wire output from the output line 3 is input as a measuring pulse.

Further, the controller 12 obtains the actual operating time from the position signal of each operating device input from each of the limit switches 11 each time the running line 9 is changed during the production operation. The actual operation time is converted into the number of measuring pulses based on the measuring pulse based on the production speed of the electric wire output from the pulse generator 13, and the actual start timing of each operating device is obtained based on the converted number of measuring pulses. . Next, the difference between the actual start timing and the initial start timing is obtained as a difference in the number of measuring pulses, and the starting timing of each operating device is automatically adjusted so that the difference in the obtained number of measuring pulses becomes zero. It serves to perform a reset operation.

A method of controlling the operation of the rewinding device by such an electric wire rewinding control device will be described below. Each of the operating devices constituting the rewinding device during the idle operation after the line operation of the electric wire covering device is started. Is performed a plurality of times, and the position signal of each operating device at the time of the simulated rewinding operation is output from the limit switch 11 to the controller 12. When the position signal of each operating device is input, the controller 12 calculates the simulated operation time of each operating device, converts the obtained simulated operating time into the number of measuring pulses based on the measuring pulse, and performs each operation. The initial start timing of the device is obtained, and the obtained initial start timing is preset. The simulated rewinding operation is intended to stabilize the initial operation of each operating device, reduce variations in operating time, and to discover malfunctions such as operating malfunctions of each operating device. It is. The number of repetitions of the simulated rewinding operation was about three times.

Then, when the electric wire winding machine is switched to the electric wire production operation after the initial start timing is preset, the traveling line 9 starts to be wound around the bobbin. For example, when the winding of the traveling line 9 is continued and a forecast signal indicating that the winding length of the running line 9 wound on one bobbin has become the “forecast length” is issued, an empty bobbin for rewinding is provided. Is started, and the bobbin 2 is rotated at a constant peripheral speed. And the traveling line 9 wound around one bobbin
When the take-up length reaches a preset “full length”, the running line 9 is changed from one bobbin to the other bobbin by the operation of each operating device.

At the time of rewinding the traveling line 9, the controller 12 calculates the actual operating time of each operating device and the winding length of the traveling line 9 based on a measuring pulse input from the pulse generator 13. The actual starting timing of each operating device is obtained by converting the actual starting timing into the obtained measuring pulse number, and the difference between the actual starting timing and the initial starting timing is obtained as a difference in the measuring pulse number. Then, the difference between the obtained measuring pulse numbers is zero.
The start timing of each operating device is automatically reset so that the next rewinding is performed. That is, such calculation and reset are performed every time the running line 9 is changed. Note that the difference between the actual start timing and the initial start timing is based on the operating resistance of each operating device, the pressure fluctuation of the operating compressed air, and the like.

Hereinafter, a method of controlling each operation device of the rewinding device by the rewinding control device will be described more specifically with reference to FIGS. 2 and 3. First, the simulated rewinding operation will be described with reference to FIG. 2. When a line operation start signal is input, the simulated operation of the electric wire covering device including the electric wire winder is started, and the process proceeds to step 1.

In step 1, when the simulated operation of the electric wire covering device including the electric wire winding machine is started, the simulated rewinding operation of the rewinding device is performed. Then, the simulated operation time data of each operation device of the rewinding device is collected. Based on the simulated operation time data, a failure such as an operation failure of each operation device of the rewinding device is confirmed.

In step 2, it is determined whether or not the number of times of collecting the operation time data of each operation device has reached a predetermined number n. If the number of collections of the operation time data of each operation device does not reach the predetermined number n, the process returns to step 1 and the collection of the operation time data is repeated. Then, when the number of collections of the operation time data of each operation device reaches the predetermined number n, Y
If it becomes es, it is determined that the operation of each operating device has been stabilized, and the process proceeds to step 3.

In step 3, the initial start timing converted into the number of measuring pulses capable of calculating the winding length of the electric wire of each operation device of the rewinding device is set, and the production operation of the electric wire is started.

Next, the production rewinding operation of each operating device of the rewinding device will be described with reference to FIG. 3. In step 4, it is first determined whether or not the rewinding operation of the electric wire has started. In the case of No where the wire rewinding has not been started, it is determined whether or not the rewinding operation has been started again. If it is determined that the rewinding operation has been started and the answer is Yes, the process proceeds to step 5.

In step 5, the rewinding operation of each operating device is performed, actual operating time data of each operating device of the rewinding device in the rewinding operation is collected, and the collected actual operating time data is counted. The actual starting timing of each operating device is calculated by converting the number into a pulse number, and the process proceeds to step 6.

In step 6, the difference between the actual start timing and the initial start timing is obtained as the difference in the number of measuring pulses, and there is no difference between the actual operation timing and the initial start timing. If it is determined that there is no need to reset, the process returns to step 5, and if there is a difference between the actual start timing and the initial start timing, the process proceeds to step 7.

In step 7, the start timing of each operating device is corrected and reset so that the difference in the measured pulse number between the actual start timing and the initial start timing becomes 0, that is, the difference in the measured pulse number. .

As described above, the difference in the number of measured pulses between the actual start timing and the initial start timing is obtained for each rewinding operation, and the start timing of each operating device is reset as necessary. As a result, the winding from the full bobbin to the empty bobbin is continued.

The control method of the main cover will be described more specifically with reference to FIG. Here, the full length of the wire wound on the bobbin is L (m), the production speed of the wire is V (m / s), the encoder output per unit wire length is _Pe (pulse / m), and the main cover is activated. It is assumed that the operation time of the cylinder is t ₂ (s). Then, the operating time Pt ₂ of the main cover operating cylinder 4a converted into the measuring pulse number is _Pe · V · t ₂ (number of pulses), and the time Ps when the bobbin is fully _loaded is L · _Pe (number of pulses). ).

[0029] Therefore, the initial start-up timing Pt ₁ (number of pulses) is P _s from Pt ₂ before the time of the main cover actuating cylinder 4a, that is, a (P _s -Pt _2). The actual start timing P at the time of rewinding operation of the main cover operation cylinder 4a
Assuming that t ₁ ′ is (P _s −Pt ₂ ′), the correction amount Pt ₃ (number of pulses) of the next start timing of the main cover working cylinder is Pt ₃ = (Pt ₁ −Pt ₁ ′) = ｛ (P _s -Pt ₂₎
− (P _s −Pt ₂ ′)｝ = (Pt ₂ ′ −Pt ₂ ), and the actual start timing of the main cover operation cylinder 4 a
It is corrected by t ₃ (the number of pulses). Of course, the auxiliary line shifting operation cylinder 3a and the main line shifting operation cylinder 5
The start timing of “a” is similarly corrected.

Accordingly, by resetting the starting timings of the respective operating devices as described above, at the time of the rewinding operation during the production operation of the traveling line 9 from the next time onward, the respective operating devices are set to the predetermined times in accordance with the end of the movement of the traverser 6. Since it is located at the rewinding position and the operation end time has no variation, the variation in the winding line length of the traveling line 9 for each bobbin is reduced. Even if the traverser 6 precedes, the stopping time of the traverser 6 is shorter than that of the conventional example, so that the number of windings of the traveling line 9 at one location of the winding bobbin is small. As a result, a wound product having an excellent winding shape can be obtained, and waste lines are reduced. The reason why the actual start timing and the initial start timing are converted into the number of measuring pulses is that the length of the waste wire wound can be determined for each bobbin, and post-processing is facilitated. is there.

[0031]

As described in detail above, claim 1 of the present invention
According to the electric wire rewinding control method for an electric wire winder according to the present invention and the electric wire rewinding control device for an electric wire winder according to the second aspect, the start timing of each operating device is reset, and the winding during the next and subsequent production operations is performed. At the time of replacement, all the operating devices are located at the predetermined rewind position in accordance with the end of the movement of the traverser, and there is no variation in the operation end time, so that the variation in the winding wire length for each bobbin is reduced. In addition, even if the traverser precedes, the stopping time of the traverser is shorter than in the conventional example, so that the number of windings on which the traveling line is wound at one location on the winding bobbin is reduced, and A product having an excellent shape can be obtained, and there is an extremely excellent effect that waste lines are reduced.
