If the tape winding described above is performed manually, it is not only inefficient but also difficult to wind the tape uniformly.
In order to solve such problems, the present applicant has developed an automatic tape winding device, for example, in Japanese Patent Application No. 58366/1983.
(Japanese Unexamined Patent Publication No. 52-85534). This automatic tape winding device includes a C-shaped frame, a C-shaped frame that is concentrically and rotatably supported by the frame, supports a tape pad directly or indirectly, and is rotationally driven by a drive source provided on the frame. The frame is provided with a drive boob with an outer circumferential groove at a position protruding in the radial direction of the frame, and a drive boob with an outer circumferential groove is provided on one concentric circle at both circumferential ends of the frame. A pair of pulleys at both ends are provided, and a plurality of intermediate pulleys with outer peripheries are provided spaced apart from each other on the one concentric circle between the pulleys at both ends; A pulley having an outer circumferential groove with a diameter smaller than a circle touching the center of the frame is provided at the bottom of the pulley at both ends and an intermediate pulley located between them, and the pulley is extended over the drive pulley and the pulley at both ends to prevent the rotation. When the pulley, which is integral with the plate and is concentric with the plate, is placed in a position concentric with the one concentric circle, it is tensioned, and the running part from the deforming pulley to the pulleys at both ends, and the pulleys at both ends and the middle pulley are connected to the center side of the frame. The outer periphery of a pulley that is in contact with the rotary plate and concentrically integral with the rotary plate forms an arcuate running portion sandwiched between the outer circumferential groove of the pulley and both end bools and the outer circumferential groove of the intermediate pulley, the cross-sectional area of which The rotary plate is supported by an endless belt that is larger in cross-sectional area than the space formed by the pair of supporting plates. [Problems to be Solved by the Invention] Although the automatic tape winding device having the above configuration can wind the tape well, it has the following problems. That is, (1) A conventional tape winding device in which a rotary plate is driven by an endless belt having a circular Ii surface has drawbacks such as uneven rotation of the rotary plate and generation of noise. ■ Furthermore, in conventional tape winding devices, the tape pad is mounted so that the end surface of the tape pad is parallel to the plane of the rotating disk, so there is a limit to the diameter of the tape pad that can be mounted. It was not possible to wind a long length of tape all at once. ■ In addition, in conventional tape winding devices, mechanical braking is applied to the tape pad using a spring or the like to apply a predetermined reserve force to the tape being wound, but it is difficult to keep the tension constant. Met. This tension stabilization tended to become more difficult as the tapered pad diameter increased. The present invention has been made based on the above-mentioned circumstances, and allows the rotation of the rotating disk to be performed without uneven rotation, noise, etc., and allows the use of a large-diameter and long tape pad. The purpose of this paper is to provide a tape winding device that can apply a certain amount of force to a certain tape. [Means for Solving the Problems] The tape winding device of the present invention includes a C-shaped frame;
A C-shaped rotating disk is supported concentrically and rotatably by the frame, carries a tape pad, and has a notch closed by a spacer that is rotatably driven by a drive source provided in the frame; and a traverser that reciprocates in the axial direction, wherein the support plate is coaxially integrated with the rotary disk and has a circumferential protrusion in the axial middle, and the protrusion of the support plate is arranged on the same circumference of the frame. The rotary disc is rotatably supported by the frame by being engaged with the constriction part of a stepped guide roller having a constriction part in the middle in the axial direction, and a drive source provided on the frame and the support plate. It is characterized by being connected by a timing belt. In the tape winding device of the present invention having the above configuration, since a timing belt and a timing pulley are used to transmit the driving force from the drive motor to the rotating disk, smooth and reliable rotation of the rotating disk is obtained. be able to. Furthermore, the tape winding device of the present invention includes a C-shaped frame driven by an l-rubber, and a C-shaped frame that is rotatably supported by the frame and has a notch that is closed by a spacer.
A tape pad support shaft having an axis perpendicular to the axis of rotation of the rotating disk is provided on a supporting plate that is perpendicular to the plate surface of the rotating disk, and this It is characterized by applying powder brake braking force to the tape pad support shaft, which varies the braking force by changing the tape pad diameter. In the tape winding device of the present invention as described above, the current applied to the powder brake is decreased as the tape pad diameter decreases, and the brake of the tape pad support shaft that applies tension to the tape is reduced as the tape pad diameter decreases. If the applied current is varied in proportion to the decrease in the moment arm of the force, the tension acting on the tape can be kept constant regardless of changes in the diameter of the tape pad. Furthermore, the tape winding device of the present invention includes a C-shaped frame driven by a traverser, and a C-shaped rotating disk rotatably supported by the frame and provided with a notch that is closed by a spacer. , a tape pad support shaft having an axis perpendicular to the rotation axis of the rotary disc is provided on a support plate vertically installed on the mask on this rotating disk, and this tape pad support shaft has a tape pad support shaft that is provided with a tape pad support shaft that is perpendicular to the rotation axis of the rotating disk. In the powder brake that applies a braking force that varies the braking force, the application of current to the powder brake is supported and guided by a guide roller that is provided concentrically with the rotating disk and provided on the frame. This is achieved through independent slip rings on the circumferential surface of the support plate and a power supply roller in contact with the slip rings. In the tape winding device of the present invention having the above structure, since power is supplied through rolling contact between the slip ring and the power supply roller, there is no generation of metal debris at the power supply site, and the tape winding is performed by winding up the metal debris. This will not cause any deterioration in the characteristics of the cable connection area. It comprises a C-shaped frame driven by a traverser, and a C-shaped rotating disk that is rotatably supported by this frame and has a notch that is closed by a spacer. A tape pad support shaft having an axis perpendicular to the rotation axis of the rotary disk is provided on an upright support plate, and a flange supporting one end surface of the tape pad and a A tape pad support plate is provided integrally with the tape pad support plate, and one end of the tape pad support plate is provided with a center of a circular cover that is in contact with the core of the tape pad that is engaged with the tape pad support shaft and the end surface of the tape pad. A circular rubber plate that fits into the opening is engaged with a washer of approximately the same shape as the circular rubber plate, and a granite cam that rotates around an axis perpendicular to the tape pad support shaft is provided at the one end at the base end. Suppose that In the above-mentioned tape winding device of the present invention, the rubber plate engaged with the tape pad support shaft bulges in the radial direction due to the pressure of the leaking cam caused by the rotation of the lever, thereby firmly holding the tape pad. There is no risk of the tape pad coming off due to the centrifugal force exerted by the rotation of the rotating disk.

These tape pad holders include a support plate 24 that stands upright on the plate surface of the rotating disk 8, as shown in FIG. 5, and are rotatably provided with an axis perpendicular to the support plate. It has a tape pad support shaft 25. As shown in FIG. 5B, this tape pad support shaft 25 has a core engaging portion near one end thereof, which is provided with L-shaped leaf springs 28 at 90° intervals, which are pressed into contact with the inner diameter of the core 27 of the tape pad 26. It has 29. These leaf springs are accommodated in L-shaped notches provided at 90° intervals in the winding center pedestal 29. Further, a lever 30 is provided at the one end and has an eccentric cam 30a at its base end that is rotated about an axis perpendicular to the axis of the tape pad support shaft 25. Furthermore, a flange 31 having a diameter larger than the winding core 27 of the tape pad is provided on a surface of the winding center holding table part 29 opposite to the lever 30. This flange has a tape pad support plate 31 which is concentrically integrated with the flange and has a diameter slightly larger than that of the tape pad 26.

A washer 34 is in contact with the upper surface of this rubber plate. Further, a brake timing pulley 35 is fixed to the other end of the tape pad support shaft 25. This brake timing pulley 35 is connected by a timing belt 38 to a brake shaft timing pulley 37 of a powder brake Ir 36 attached to the support plate 24, as shown in FIG. Note that the powder brake 36 is made of magnetic housing 3.
9, the same magnetic brake shaft housed therein, magnetic powder filled in the housing surrounding the brake shaft, and a coil that magnetizes the housing, the magnetic powder, and the brake shaft when energized. By adjusting the current applied to the coil, any suitable braking force can be obtained. Power is supplied to the powder brake 36 by a power supply roller 40 that slides into contact with the bottom surface of the grooves 9b and 9b of the supporting plate 9, which is coaxial with the rotary disc 8. The above-mentioned brake mechanism and brake force automatic adjustment means are shown in detail in FIG.

Furthermore, the tape 26 pulled out from the tape pad 26
A is sent to the dancer roller section 42 via a guide roller 41 provided at the tip of the support plate 24 with its axis perpendicular to the support plate, and then guided to the tape winding section via there. The dancer roller section 42 is composed of a guide roller having an axis perpendicular to the tape support shaft 25 (an axis parallel to the tape winding axis).
The tape 26a is twisted by 90 degrees between the guide roller 41 and the dancer roller section 42 and introduced into the dancer roller section 42. Further, the support plate 24 is provided with a tape pad diameter detection potentiometer 43, and the rotation axis of this potentiometer is operated by the spring pressure of the spring 44 disposed between the base end and the support plate 24. A tape pad diameter detection lever 45 is attached that constantly presses the tape pad 26 against the outer periphery of the tape pad 26. The resistance value of the potentiometer 43 increases as the tape pad 26 decreases and the tip of the tape pad diameter detection lever 45 moves to the left in FIG. The tape pad diameter detection potentiometer 43 is connected in series to the power source (each of the independent terminals). Therefore, as the tape pad diameter decreases, the current applied to the powder brake 36 decreases, and the braking force generated thereby decreases. The tape winding device of the present invention constructed as described above operates as follows. That is, the lever 30 of the tape pad support part 23 is released, and the core engaging part 29 of the tape pad support shaft 25 is compressed while compressing the leaf spring 28 to compress the core 27 of the tape pad 26 .
and press down until the lower surface of the tape pad 26 contacts the tape pad support plate 31a. Here, the lever 30 is controlled and the large diameter part of the eccentric cam 30a at the base end presses the rubber plate 33 through the washer 34, causing it to bulge in the radial direction, and the outer periphery of the rubber plate 33 is inserted into the center hole of the cover 32 and Place it close to the inner circumference of the winding core 27. With the spacer 7 of the rotating disk 8 and the spacer of the support plate 9 (numerical numbers omitted for simplicity of illustration) removed, the tape of the present invention is wound from the cut arrow part thereof to the tape winding part, that is, the cable connection part. Tape 2 pulled from each tape pad 26 by engaging the device
6a is twisted by 90'' and guided to the dancer roller section 42 via the guide roller 41, and the leading end of each tape is fixed at the tape winding start position of the tape winding section via this.

In this state, the timing pulley 16 is activated by the motor 20, and the rotating disk 8 is rotated via the timing belt 22, the supporting plate 9, which is coaxial with the rotating disk 8, and the timing pulley 11. At the same time, the motor 3 is started to alternately rotate the ball screw 4 in forward and reverse directions at the required intervals, causing the frame 1 to move back and forth (traverse) at the required intervals. The powder brake provided on the rotating disk 8 is supplied with power through the groove 9b of the support plate 9 and the power supply roller 40 in contact with the groove 9b even when the rotating disk 8 rotates and the frame 1 traverses. The braking force of the powder brake 36 is variable depending on the applied current, and this changing force is transmitted to the tape pad support shaft 25 via the timing belt 38 and timing pulley 35, and is fed out from the tape pad 26. This causes a change in the tension of the tape being applied. However, as described above, since the powder brake is connected in series with the tape pad diameter detection potentiometer 43 that increases the resistance value as the tape pad diameter decreases, the current applied to the powder brake 36 varies depending on the tape pad diameter. decreases, and the generated braking force also decreases. Therefore, if the resistance value of the potentiometer 43 is changed in accordance with the applied current in proportion to the decrease in the tape pad diameter, that is, the decrease in the moment arm of the brake force of the tape pad 25 that applies tension to the tape, the resistance value of the potentiometer 43 can be changed in accordance with the applied current. The tension acting on the tape can be kept constant regardless of changes in diameter. As is clear from the above, in the tape winding device of the present invention, since the tape pad is mounted so that the end surface of the tape pad is perpendicular to the plane of the rotating disk, the diameter of the tape pad that can be mounted is It is possible to increase the size of the tape and wind a long tape at once.

Furthermore, the rubber plate engaged with the tape pad support shaft expands in the radial direction due to the pressure of the eccentric cam caused by the rotation of the lever, and in order to firmly hold the tape pad, the centrifugal force exerted by the rotation of the rotating disk causes the tape to There is no risk of the pad coming off. Furthermore, the tape winding device of the present invention constantly detects the tape pad diameter while winding the tape, and selects the optimal play-it for the tape pad according to the tape pad diameter.
Since the force is applied, the tape tension can be kept constant during tape winding, and uniform and good tape winding can be achieved. In addition, in the present invention, since the force is applied to the tape pad by electrical means, it is possible to provide a brake device with a simple structure and high precision. Further, in the present invention, since a timing belt and a timing pulley are used to transmit the driving force from the drive motor to the rotating disk, smooth and reliable rotation of the rotating disk can be obtained. In addition, in the tape winding device of the present invention having the above configuration,
Since power is supplied through rolling contact between the slip ring 9c and the power supply roller 40, there is no generation of metal debris at the power supply site, and the characteristics of the tape winding section, that is, the cable connection section, are affected by the entrainment of metal debris at the power supply site. Although this does not cause any deterioration, the characteristics of the tape winding part, that is, the gable connection part, may deteriorate due to the entrainment of metal powder caused by friction between various parts of the tape winding device and dust that has adhered to the tape pad. To completely prevent dust removal, a removable dust removal cover 46 is attached to the frame 1 as shown in FIG.
It is a good idea to provide The dust removal cover 46 is made of synthetic resin or metal such as aluminum, and has an outer peripheral surface 46a that matches the inner peripheral surface of the frame 1, as shown in FIGS. 8A and 8B. The lower part is equipped with a dirt catcher 46b in which metal powder, dirt, etc. accumulate. Metal powder, dust, etc. generated from the tape winding device and tape pad are removed from the outer peripheral surface 46a.
This prevents deterioration of characteristics due to entrainment of metal powder, dust, etc. at the tape winding portion, that is, the cable connection portion. Further, the dust removal cover 46 may have a structure as shown in FIGS. 8A and 8B as long as it has a structure that prevents metal powder, dirt, etc. from sliding down the outer peripheral surface 46a and adhering to the cable connection part. However, the present invention is not limited to this, and for example, a structure may be adopted in which the garbage reservoir 46b is omitted. [Effects of the Invention] As described above, according to the tape winding device of the present invention, it is possible to reliably and uniformly wind the tape, so that, for example, the insulator of the cable connection part of a CV cable, etc. The connection between them can be made good and uniform, and the reliability of the connection part can be improved.
