Abstract

PURPOSE:To make it possible to practice changeover operation of an initial speed set value without stopping a take-up machine by providing a memory circuit at an initial speed setting unit in the speed control device of the take-up machine, memorizing an initial speed set value input in the setting unit at the time of stopping the take-up operation and practicing the speed control based on the set value memorized during the take-up operation. CONSTITUTION:In the case when a take-up machine stops, a relay 11b forms a closed circuit, and an initial speed set value input in a setting unit 4 in the speed control device (control unit) 5 of the take-up machine is memorized in a memory circuit 17. Thereby, the initial speed set value memorized in the memory circuit 17 is input in an adder 10 through an amplifier 18 and even when the initial speed set value is changed during the take-up operation, no influence is given to an instruction signal to an inverter. By this inverter, a spindle driving electric motor in the take-up machine is controlled in its rotation based on the instruction signal.

(Prior art and its problems) In general, the winding speed control of a spindle-driven winder is based on gradually decreasing the spindle rotation speed from the initial speed setting in accordance with the winding diameter. The control system is shown in FIG.

That is, an electric motor 2 to which a spindle 1 for mounting a bobbin for winding a bobbin is connected, a tension detector 3 for detecting winding tension, a setting device 4 for inputting winding tension, initial speed, etc., and a control section 5. , an inverter 6 that controls the rotation of the electric motor 1112 based on signals from the control section 5, and a sequencer 7 that outputs operation control signals.
, a tension control section 9, an adder 10 that adds or subtracts the signal from the tension control section to the signal from the initial speed setting section, and a sequencer for inputting the signal from the tension control section to the adder 10.
When the winding tension is detected and inputted to the controller section 5, the set value and the detected value are compared and the winding thickness is detected. When the value becomes larger than the set value, the relay 11a operates based on the operation signal from the sequencer 7, lowering the frequency output from the inverter 6 to the electric motor 2, reducing the rotational speed of the electric motors 1 and 2, and reducing the tension. Winding is controlled to match the set value.

The relationships among the signals from the start of winding to the end of winding are shown in FIG.

In addition, in yarn production factories, one setting device is installed for multiple winding machines installed in one winding equipment to control the winding of each winding machine. . Therefore,
Due to the yarn quality of the innermost layer of the package, even if the initial speed constant value is changed by a small amount, say 1% or less, multiple winding machines must be stopped each time, and winding machine stoppages and In addition to causing a time loss for the start-up operation,
Threading has problems such as an increase in the workload for operation and an increase in the amount of waste thread generated. Therefore, if a constant initial speed number is input to the setting device 4 during the yarn winding operation without stopping the winding machine, the set value is immediately input from the initial speed setting section 8 to the adder 10, and its influence is eliminated. It appears in the rotation speed of spindle l, and the amount of change is 10. Even if it is 5%, it will be 12% when the package is almost full.
This causes problems such as yarn breakage due to a decrease in tension and troubles such as the inverter 6 becoming uncontrolled due to back power due to sudden deceleration.

It is composed of an inverter 6 that controls the rotation of the motor, and a sequencer 7 that outputs a rotation control signal. The details of the control section 5 are as shown in FIG.
It is comprised of a memory circuit 17 that stores the set value of the preamplifier 16 via a relay 11b operated by an operation signal from the preamplifier 16, and an amplifier 18 that amplifies the set value and outputs it to the adder IO.

The set value from the setting unit 4 in the control unit 5 described above is such that the relay 11b operates at the same timing as the operation signal of the winding machine, and when the winding machine is stopped, the relay flb forms a closed circuit and the set value is input into the memory circuit, but when the winder is in operation, the relay 11b forms an open circuit and the set value is not input.
