BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable winding device for winding an electric cable, and more particularly to a cable winding device using an under roll.

[0002]

2. Description of the Related Art Conventionally, in a cable manufacturing process, a cable winding device for winding a manufactured cable around a drum has been used. 3 and 4 are a front view and a plan view of a conventional cable winding device, respectively, and the same parts are denoted by the same reference numerals.

In FIGS. 3 and 4, the under rolls 306 and 307 are rotated by a motor (not shown). Cable 3 on under rolls 306 and 307
A drum 305 for winding the ten is mounted. When the under rolls 306 and 307 rotate, the drum 305 rotates due to friction with them. A predetermined tension is applied to the cable 310 by a dancer roll 301 rotatably held on the floor in order to improve winding. In order to prevent the drum 305 from inclining, drum holding rollers 308 rotatably held around a vertical direction as a rotation axis are disposed near both side surfaces of the drum 305. After the winding of the cable 310 onto the drum 305 is completed, the drum 305 is
Drum kick roll 304 to kick from 307
It is held by air cylinders 302 and 303 fixed to the floor.

When winding the cable 310 from a take-up machine (not shown), the under rolls 306 and 307 are rotated in the direction of the arrow. The drum 305 includes the under roll 30
The cable 310 is rotated in the direction of the arrow due to friction with 6, 307, whereby the cable 310 is wound around the drum 305. At this time, a predetermined tension is applied to the cable 310 by the dancer roll 301 and the drum pressing roller 308 is provided.
Prevents the drum 305 from shifting in the direction of the rotation axis, so that the cable 310 can be wound around the drum 305 satisfactorily.

[0005]

Even if the diameter of the drum 305 is large and the drum 305 itself is heavy to some extent, or even if the diameter of the drum 305 is small and light, the cable 310 is wound by a predetermined amount to increase the weight of the drum 305. In this case, a stable winding operation can be performed as described above. However, in the case of the small-diameter and lightweight drum 305, the weight of the drum 305 including the cable is small at the time when the winding amount of the cable is small, and therefore, as shown in FIG. Pulled to
It was lifted from the under roll 307 and was difficult to wind up.

In order to prevent this, in a conventional cable winding device, a drum 305 is rolled by a drum kicking roll 304 held by air cylinders 302 and 303.
Was holding on. However, even with this method, the drum 30
5 may slightly rise from the underroller 307, so that the underroller 307 idles, and there is a problem that stable winding is difficult. Also, since the drum 305 is raised, in the worst case the drum 305
However, there was a problem in that it fell down from the underrolls 306 and 307 and lacked safety.

As a method for solving this problem, a method in which hook-shaped support bars are inserted into both sides of the rotary shaft hole 311 of the drum 305 and the support bars are fixed to the floor is also conceivable. However, since there are various types of drums 305 and their sizes are not constant, there is a problem that the above method cannot be applied to drums of various sizes.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to perform a stable winding without the drum being lifted from the under roll, and to be able to cope with a drum of various sizes. It is intended to provide a picking device.

[0009]

The cable winding device of the present invention is a cable winding device for winding a cable around a drum placed on the underroll by rotating and driving the underroll. A pair of roller holding members disposed near both side surfaces and movably held in a direction parallel to the rotation axis of the drum; a pair of rollers rotatably fixed to the respective roller holding members; It has a pair of pintle stand holding members that move integrally with the holding member, and a pair of pintles that engage with the rotation shaft hole of the drum, and a pair of pintle stand members that are held by the respective pintle stand holding members in a state where their heights are variable. And a pintle stand.

[0010]

In the case of a small-diameter and lightweight drum, the drum is rotated by an underroll while being held by a pintle stand that moves integrally with the roller holding member. In the case of a large-diameter drum, the drum is simply placed on the underroll. It is driven to rotate by an under roll while being placed. Thereby, the floating of the drum from the under roll is prevented, and good winding is performed regardless of the type of the drum.

1 and 2 are a front view and a plan view, respectively, showing an embodiment of the present invention, and the same parts are denoted by the same reference numerals. In FIG. 1, for convenience of explanation, an underroll is omitted. In FIGS. 1 and 2, a cylindrical press roller moving screw 111 disposed at the center of the under rolls 201 and 202 has opposite thread portions 112 and 113 at the same pitch from the center toward both ends. Are formed. Each of the presser roller moving screws 111 has
A roller holding member 109 screwed with the screw portions 112 and 113,
110 are provided. Roller for cylindrical drum holder 1
Each of the roller holding members 109 and 110 is provided such that the extension of the rotation axis thereof intersects with the extension of the rotation axis of the drum, that is, the roller holding members 109 and 110 are rotatable about the rotation axis parallel to the radial direction of the drum. Axle-mounted. Roller holding member 10
9 and 110 are provided integrally with the stand support 10
3, 104 are fixed. Stand support stand 103,
104 moves integrally with the roller holding members 109 and 110, respectively. Each of the stand receiving stands 103 and 104 is a cylindrical member having a cavity therein. Each of the stand receiving stands 103 and 104 has, at its end, a drum holding pintle 116 having a diameter smaller than the rotation shaft hole of the drum.
Pintle stands 101 and 102 having 117 are inserted and fixed by thumb screws 105 and 106.

On the other hand, the presser roller moving screw 111 is connected to the handle 115 via a chain 114. The presser roller moving screw 111 rotates the handle 115 in the forward or reverse direction, thereby turning the handle in the forward or reverse direction. It rotates in the direction. The operation of the cable winding device of the present invention configured as described above will be described. First, a case where a cable is wound around a small-diameter drum 118 indicated by a broken line will be described.

In this case, first, the drum 118 is placed on the under rolls 201 and 202. Next, the thumb screw 10
5 and 106 are loosened and the pintle stands 101 and 102 are slid up and down, and fixed to the rotary shaft hole 120 of the drum 118 at a position where the pintles 116 and 117 face each other. next,
The rotation shaft hole 120 of the drum 118 is
7, the handle 115 is rotated in a predetermined direction. Since the rotation of the handle 115 is transmitted to the pressing roller moving screw 111 via the chain 114, the pressing roller moving screw 111 rotates in a predetermined direction. With the rotation of the holding roller moving screw 111, the roller holding members 109 and 110 screwed with the screw 111 move. At this time, screw part 1
Since the rollers 12 and 113 are cut in the opposite direction at the same pitch, the roller holding members 109 and 110 move by the same amount in the opposite directions to each other. As a result, the drums 118 are rotatable about the rotation shaft holes 120 so that the pintles 116 and 11 can rotate.
7 is engaged.

When the cable is wound around the drum 118 in this state, the under rolls 201 and 202 are driven to rotate by a motor (not shown). The drum 118 rotates by friction with the under rolls 201 and 202, and the cable is wound around the drum 118. At this time, the drum 11
8 is rotatably engaged with the pintles 116 and 117, so that it is prevented from floating. Drum 1
Even if the roller 18 is displaced in the rotation axis direction, the drum holding roller 1
07 and 108 prevent the displacement. Therefore, a favorable winding operation can be performed.

Next, a large-diameter drum 119 indicated by a dashed line is shown.
The case in which the cable is wound around will be described. In this case, first, the pintle stands 101 and 102 are removed by loosening the thumb screws 105 and 106, and then the drum 119 is placed on the under rolls 201 and 202.

Next, by rotating the handle 115 in a predetermined direction, the roller holding members 109 and 110 are moved, and the drum pressing rollers 107 and 108 are arranged near both side surfaces of the drum 119. When winding the cable 310 around the drum 118 in this state, the under roll 201,
202 is driven to rotate by a motor (not shown). The drum 118 rotates by friction with the under rolls 201 and 202, and the cable is wound around the drum 118. At this time, since the large-diameter drum 119 itself is heavy, the drum 119 performs the winding operation without being lifted. Also, the drum 119 is prevented from shifting in the rotation axis direction by the drum pressing rollers 107 and 108.

In this embodiment, the roller holding member 10
Reference numerals 9 and 110 denote holding roller moving screws 11 to be screwed with the screws.
Although the movement is performed by using the number 1, it is also possible to adopt a configuration in which the movement is performed simply by sliding. The pintle stands 101 and 102 are
5 and 106, the heights of the pintle stands 101 and 102 can be changed by screwing the pintle stands 101 and 102 and the stand support stands 103 and 104. It is also possible.

Further, in the case of the large-diameter drum 119, the pintle stands 101 and 102 are detached.
The pintles 116 and 117 may be prevented from obstructing by allowing the pintle stands 101 and 102 to rotate with respect to the stand receiving stands 103 and 104 so that the pintles 116 and 117 can be turned in the opposite direction to the drum 119. Further, the pintles 116 and 117 are
The pintle stands 101 and 102 may be movable so as to be higher than the top of the table 9.

As described above, according to the cable winding device of the present embodiment, the drum can be stably wound without being lifted from the under roll. Further, it is possible to perform the winding operation irrespective of the diameter of the drum. Further, the roller holding members 109 and 11
Since 0 moves in the opposite direction by the same distance from each other, even if the size of the drum changes, the center position of the drum wants to change, so that a good winding operation can be performed.

[0020]

According to the present invention, in particular, there is provided a pair of pintle stands having a pintle engaged with a rotary shaft hole of a drum and held by a pintle stand holding member at a variable height. Therefore, it is possible to prevent the drum from rising from the under roll regardless of the size of the drum, and it is possible to perform stable winding.
