Abstract

PROBLEM TO BE SOLVED: To prevent the elongation and disconnection of a wire material by controlling the delivery tensile force of the wire, which is fluctuated in response to the quantity of winding of the wire material wound around a delivery bobbin through previously controlling a motor speed in consideration of feed length and speed of the wire. SOLUTION: After inputting the data of outer diameter value of a wire material 8, kind of a bobbin 2 wound with the wire material, length of the wound wire and delivery tensile force or the like with an operation panel 4, a winding machine or the like is started, and the wire material drawing force is generated so as to start the transference of the wire material 8. At the same time, the output from a measurer and a wire speed meter 5 for continuously detecting the transference length and the transferring speed of the wire material 8 is sent to a motor 1 having an electromagnetic brake, of which braking force is changed by the input voltage, by a control circuit 9, and delivery is started at a constant delivery tensile force of the wire, which is fluctuated in response to the quantity of winding of the wire material 8 around the bobbin 2. Output of a position detecting unit 7 for continuously detecting the positional displacement of a dancer roll mechanism 3 is sent to the motor 1 by the control circuit 9, and the rotating speed of the motor 1 is controlled so as to absorb an error due to the control of the delivery bobbin 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filament feeder for feeding a filament with a constant tension.

[0002]

2. Description of the Related Art FIG. 2 relates to a conventional filament feeding device, in which a filament W is wound and is driven to rotate by a motor 30, and a feeding bobbin 20 is provided on the same frame 10 as the feeding bobbin. Fixed guide roller 40 that is arranged and fixed
And a movable guide roller 50 installed between the fixed guide roller and the delivery bobbin and installed in the frame 10 so as to be movable back and forth substantially in the delivery direction of the linear body W.
A position detection sensor 70 for detecting the movement of the motor and taking out the movement amount as an electric signal, and a circuit 90 for controlling the rotation speed by sending an electric signal emitted from the position detection sensor to the motor. . (Actual exploitation 59-4
(No. 0260)

[0003]

In the above-described filamentous body feeding device, the fact that the tensional variation of the filamentous body actually occurs causes the position detection sensor 7 to move the movable portion of the movable guide roller 50 by the tensional variation.
Since it is detected at 0 to control the rotation speed of the motor, in the case of an extra fine wire or the like, there is a possibility that elongation, disconnection or the like may occur.

Based on the above-mentioned prior art, the present invention prevents the elongation and disconnection of the filamentous body by feeding the filamentous body with a constant tension that varies depending on the winding amount of the filamentous body on the bobbin. The present invention is intended to provide a striatal delivery device.
