Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire winding of a rod bar used for measuring and smoothing a coating material applied to a substrate such as paper or a synthetic resin film. The present invention relates to a wire winding device for a rod bar that performs the following. Conventionally, a magnetic recording medium such as a magnetic card or a magnetic tape has been coated with a magnetic paint composed of a magnetic powder, a resin binder, a solvent and the like on the surface of a substrate such as paper or a synthetic resin film, and dried. To form a magnetic layer. When applying this magnetic paint, apply excess coating solution to the substrate using an applicator roll or nozzle, blade,
Excessive coating liquid is scraped off by pressing a rod bar, air knife, roll, etc., and weighed to a predetermined coating amount.
In addition, smoothing is performed. [0003] Among them, a rod bar is suitably used because a predetermined amount of magnetic paint can be applied at a high speed, and the rod bar has a diameter of 2 to 20 mm and a length of 500 mm.
A fine rod of stainless steel or the like having a diameter of about 0.1 to 0.5 mm is densely wound around a metal rod of about 2000 mm around an aligned winding, and from the curved portion of the outer diameter of the wire lined up in the aligned winding. Excessive coating liquid applied to the base cloth is scraped off by the irregularities, and a predetermined amount is uniformly applied in the width direction. [0004] However, when the above-mentioned rod bar is used in a magnetic paint application device, the wire surface is severely damaged due to abrasion of the magnetic paint and the base material, and is stable against long-term continuous operation. At present, it is difficult to maintain the applied coating quality, and the rod bar must be replaced with a new rod bar every predetermined operation time as a consumable. Conventionally, the work of manufacturing a rod bar by wrapping a stainless steel wire around a metal rod had no other choice but to rely on manual labor, but it was very difficult to wrap a thin metal rod tightly while winding it on a aligned winding while applying a predetermined tension. There has been a demand for further improvements in terms of finishing accuracy, such as uneven winding and uneven tension, as well as workability. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an apparatus for manufacturing a rod bar by winding a wire around a metal rod in a traverse direction with a uniform tension around an aligned winding.

A rod centering means 30 comprising 31c is provided. The wire winding device 1 for a rod bar is provided with a wire 3 supplied with tension from a traverse means 20.
Is wound by rotating the rod 2 fixed to the winding means 10 so that the traverse means 20
While winding the wire 3 around the rod 2 while moving in the traverse direction A (left direction in FIG. 1) along the rod, the rod centering means 30 prevents the rod 2 from being distorted due to the tension applied to the wire 3. It enables precise winding while pivoting. 5 is an operation panel, and 6 is a base. The winding means 10 comprises a drive motor 11 for rotating the rod 2 around a shaft, and a pair of rod chucks 13a and 13b provided on the drive motor 11 and a rotation shaft 12 facing the drive motor 11. The rod chucks 13a and 13b are air-operated so that the rod 2 can be attached and detached. The number of rotations of the drive motor 11 is 20
It is preferably 0 to 2000 rpm, and any setting can be made depending on the diameter of the rod 2 or the diameter of the wire 3. The rod 2 is usually a stainless steel rod that can be soldered, and has an outer diameter of 2 to 20 mm and a length of 500 to 200 mm.
A rod having a diameter of 0 mm is frequently used, and a handle 14 for manual operation is provided for adjusting the length between the rod chucks 13a and 13b at both ends in accordance with the rod length.
The rod 2 is attached and detached by adjusting the length between the rod chucks 13a and 13b by using it. As shown in FIGS. 3 and 4, the traversing means 20 includes a tension detecting unit 21 for detecting the tension of the wire 3 and a wire 3 while the wire winding bobbin shaft 27 is brake-controlled by the detected tension signal. , A position detecting unit 23 for detecting the position of the wire 3 immediately before being wound around the rod 2, and a rod centering unit 31 for pivotally supporting the rod 2. The tension detecting section 21 is composed of three tension rollers 24a, 24b, 24c and a tension converter 21a, and detects a load applied to a central tension roller 24b among the three tension rollers. 21a. And wire 3
Is provided with a brake control system 25, which controls the wire winding bobbin shaft 27 based on the tension signal detected by the tension detection unit 21 while applying a predetermined tension to the wire 3 from the transmission unit 22. The wire 3 is sent out, and is sent out to the rod 2 via a traverse guide 26 which is a grooved roller. The brake control system 25 preferably uses a hysteresis brake, but is not limited to this. Further, the tension applied to the wire 3 is preferably 0.1 to 10 kg, more preferably 0.2 to 5 kg. The position detecting section 23 is an optical type using visible light. The light receiving section receives a change in the amount of light after irradiating the wires 3 with light beams from a plurality of light emitting sections (not shown). Then, the incident angle α between the rod 2 and the wire 3 shown in FIG. 5 is measured, and based on the measurement result, the drive motor 7 of the traverse means 20 is driven to move the traverse means 20 so as to maintain the predetermined incident angle α. Controlling speed. The preferred angle of incidence is 70-85 degrees. The moving speed of the traversing means 20 for winding the wire 3 around the rod 2 in an aligned winding is basically the same as the traversing means 20 is moved outside the wire 3 while the winding means 10 of the wire 3 makes one rotation of the rod 2. It is only necessary to move a distance equal to the diameter, but the outer diameter usually used is 0.1 to
The 0.5 mm stainless steel wire has an eccentricity difference of 2 to 4%. Therefore, if winding is performed at a set constant speed, the eccentricity difference accumulates, and the arrangement of the wires 3 is disturbed. Impossible. Therefore, by controlling the moving speed of the traverse means 20 at a predetermined angle α with respect to the rod 2 by the signal from the position detection unit 23 as described above, the wire 3 having the eccentricity difference is controlled by the predetermined angle α. With this tension, it is possible to precisely arrange winding. The traverse means 20 is provided with a rod centering portion 31 for pivotally supporting the rod 2. The rod centering portion 31 is provided to prevent the rod 2 from being distorted by being pulled toward the wire 3 supply side while being wound while applying a predetermined tension to the elongated rod 2. If the wire 2 is distorted toward the wire 3 supply side when the wire 3 is wound around the rod 2, the wire 3 is roughly wound on the wire 3 supply side of the rod 2 and densely wound on the opposite side, so that the wire 3 is evenly distributed. It becomes impossible to be wound in a line. As shown in FIG. 6, the rod centering portion 31 has support arms 32 provided at three positions.
a, 32b, and 32c, a rotating ring 33
The support arm 32a moves forward and backward, and the support arms 32b and 32c pivot in the direction of the arrow Y to support or release the rod 2.

The rod centering portion 31 moves forward and backward on the guide rail 34 by the action of the cylinder 35, thereby enabling the rod 2 to move to the support position or the open position. In the present invention, a wire surface degreasing bath 28 can be provided as required. The bath is filled with a solvent, and the wire 3 is allowed to pass through the solvent so that the grease attached to the wire 3 can be washed. In the present invention, as shown in FIG. 3, a drive motor 7 for moving the traverse means 20 and a speed reducer 8 are mounted, and the drive motor 7 is connected to the drive motor by a connecting means (not shown) using a timing belt 9. The driving force is transmitted to the traverse means 20, and the traverse means 20 is moved along the guide rail 4 from the drive motor 11 side of the winding means 10 in the facing direction A (to the left in FIG. 1). The rod centering means 30 comprises three rod centering parts 31a, 31b and 31c having the same structure as the rod centering part 31, and in FIG.
