Description

[Detailed Description of the Invention] [Background and Objectives of the Invention] The present invention relates to an automatic winding tension setting device for a winding rotation type twisting machine, and particularly a microcomputer suitable for greatly contributing to labor saving and automation. The present invention relates to an automatic winding tension setting device using a winding tension automatic setting device.

The winding machine of the winding rotation type twisting machine is usually driven by a torque motor, and the winding tension is
This is done by changing the voltage applied to the torque motor. By the way, in the past, changing the voltage was all done manually. Furthermore, this work varies depending on the size of the wire to be wound, length, wire bundle, drum type, etc.
In particular, because the length changes depending on the length of the strip, the worker is not freed from the machine, which is a major problem in terms of labor savings. Additionally, since it is done manually, there is a possibility of mistakes such as incorrect settings, so there was a strong desire to automate this process.

The present invention has been made in view of the above, and an object of the present invention is to provide an automatic winding tension setting device for a winding rotation type twisting machine that can save labor and achieve automation.

[Summary of the invention] The features of the present invention include a wire bundle, winding length, wire size,
It is equipped with a microcomputer system that takes in the drum size, etc., and the microprocessor of this microcomputer system controls the torque motor that drives the winding drum that winds the wire from the winding rotation type twisting machine in advance according to each of the above inputs. Either pick up the appropriate data from the voltage table that stores the applied voltage data, or calculate the appropriate data using the calculation formula stored in the standard calculation formula table and apply the command value to the voltage control system of the torque motor. The point is that the structure is given as follows.

[Examples] The present invention will be described in detail below using examples shown in FIGS. 1 to 3.

FIG. 1 is a block diagram showing an embodiment of an automatic winding tension setting device for a winding rotation type twisting machine according to the present invention. In FIG. 1, 1 is an electric wire, 2 is a wire flux detection roller, 3 is a generator that obtains a voltage proportional to the linear velocity, and 4
is a linear speed digital meter that uses the voltage from the generator 3 as a digital signal, 5 is a wire length counter, 6 is a wire size setting digital switch, 7 is a drum size selection switch, 8 is a winding drum for winding the electric wire 1, and 9 is a winding drum. Torque motor for driving the removal machine, 10 is torque motor 9
11 is a microcomputer system, and 12 is a main power supply for the torque motor.

The digital signal from the linear speed digital meter 4, the amount of wire wound on the drum 8 from the wire length counter 5, the output of the wire size setting digital switch 6, and the output of the drum size selection switch 7 are input to the microcomputer system 11. , the microcomputer system 11 performs predetermined processing using these values, and outputs a command value 4 to the torque motor voltage control device system 10.

FIG. 2 is a schematic block diagram showing one embodiment of the microcomputer system 11 of FIG. 1.
Input of line speed, strip length, line size, drum type, etc. 13
is taken into the microprocessor 15 via the input interface 14. Here, the voltage data applied to the torque motor 9, which has been determined in advance by actual measurements or calculations for the entire device, is tabulated and stored in a voltage data table 16.
From this data table 16, the microprocessor 15 picks up appropriate data matching the input 13 and outputs it as a command value A via the output interface 17.

According to the embodiment of the present invention described above, the microprocessor 1 is connected to the torque motor voltage control system 10.
Since the command value A is output from 5, manual work is eliminated and labor can be saved. Moreover, since it is automated, it can be adjusted more finely than by manual adjustment, and the winding condition is improved.

FIG. 3 is a block diagram corresponding to FIG. 2 showing another embodiment of the present invention, and the same parts as in FIG. 2 are designated by the same reference numerals, and the explanation thereof will be omitted here. In FIG. 3, the voltage data table 16 of FIG. 2 is replaced with the standard calculation formula table 18. That is, the microprocessor 15 calculates using the calculation formula in the standard calculation formula table 18 based on the input 13, and outputs the command value A. The above calculation formula was obtained from simulation results using a large computer based on actual data. Even in this case, the same effect as in the case of FIG. 2 can be obtained.

Furthermore, the present invention is not limited to a winding rotation type twisting machine, but can also be applied to a device that adjusts the winding tension in an open loop using a torque motor.

[Effects of the Invention] As explained above, according to the device of the present invention, since the torque motor voltage control is automated, manual work is eliminated and labor saving can be achieved. This method has the advantage of allowing finer adjustment than manual adjustment and improving the winding condition.
