Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable winding device for winding an electric cable, and more particularly to a cable winding device using an underroll.

[0002]

[Prior Art]

 2. Description of the Related Art Conventionally, in a cable manufacturing process, a cable winding device for winding the manufactured cable on 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 designated by the same reference numerals.

In FIGS. 3 and 4, the underrolls 306 and 307 are rotationally driven by a motor (not shown). A drum 305 for winding the cable 310 is placed on the underrolls 306 and 307. When the underrolls 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 which is rotatably held on the floor in order to improve winding. In order to prevent the drum 305 from tilting near the both side surfaces of the drum 305, a drum pressing roller 308 rotatably held about the vertical direction as its rotation axis is arranged. A drum kick roll 304 for kicking the drum 305 from the under rolls 306 and 307 after the winding of the cable 310 around the drum 305 is completed is held by the air cylinders 302 and 303 fixed to the floor. ing.

When winding the cable 310 from a take-up machine (not shown), the under rolls 306 and 307 are rotated in the arrow direction. The drum 305 rotates in the direction of the arrow due to the friction with the underroll 306,307, whereby the cable 310 is wound around the drum 305. At this time, a certain tension is applied to the cable 310 by the dancer roll 301, and the drum pressing roller 308 prevents the drum 305 from being displaced in the rotation axis direction. It can be wound well.

[0005]

[Problems to be solved by the device]

 If the diameter of the drum 305 is large and the drum 305 is heavy to some extent, or if the diameter of the drum 305 is small and the drum 305 is small and the cable 310 is wound up by a predetermined amount and the weight of the drum 305 increases, as described above, A stable winding operation is possible. However, in the case of the small diameter and light weight drum 305, the drum 305 including the cable is light in weight at the time when the winding amount of the cable is small. Therefore, as shown in FIG. It was pulled to the side and floated from the underroll 307, making it difficult to wind.

In order to prevent this, in the conventional cable winding device, the drum kicking roll 304 held by the air cylinders 302 and 303 presses the drum 305. However, even with this method, since the drum 305 may float slightly from the underroll 307, there is a problem that the underroll 307 idles and stable winding is difficult. Further, since the drum 305 floats, in the worst case, the drum 305 rolls off from the underrolls 306 and 307, which causes a problem that the safety is poor.

As a method for solving this problem, a method of inserting hook-shaped support rods on both sides of the rotary shaft hole 311 of the drum 305 and fixing the support rods to the floor can be considered. However, since there are various types of drums 305 and their sizes are not constant, there is a problem that the above method cannot deal with drums of various sizes.

The present invention has been made in view of the above-mentioned problems, and it is possible to perform stable winding without causing the drum to float from the underroll, and to be applicable to drums of various sizes. An object is to provide a cable winding device.

[0009]

[Means for Solving the Problems]

 The cable winding device of the present invention is a cable winding device for winding a cable on a drum placed on the under roll by rotating the under roll, the cable winding device being arranged near both side surfaces of the drum. A pair of roller holding members that are movably held in a direction parallel to the rotation axis of the drum, a pair of rollers that are rotatably fixed to the roller holding members, and move integrally with the roller holding members. A pair of pintle stand holding members and a pair of pintle stands that are held by the respective pintle stand holding members in a state in which the pintle is engaged with the rotary shaft hole of the drum and the height of which is variable. It is characterized by being prepared.

[0010]

[Action]

 In the case of a small diameter and light weight drum, it 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, it is simply placed on the underroll. It is rotatably driven by the under-roll in the state of being rolled. This prevents the drum from rising up from the underroll and ensures good winding regardless of the type of drum.

【Example】

 1 and 2 are a front view and a plan view, respectively, showing an embodiment of the present invention, and the same parts are designated by the same reference numerals. In FIG. 1, the underroll is omitted for convenience of explanation. In FIG. 1 and FIG. 2, the cylindrical pressing roller moving screw 111 disposed in the center of the underrolls 201 and 202 has screw portions 112 and 113 in opposite directions at the same pitch from the center to both ends. Are formed. The pressing roller moving screw 111 is provided with roller holding members 109 and 110 which are screwed into the screw portions 112 and 113, respectively. Each of the cylindrical drum pressing rollers 107 and 108 is rotatable about an axis of rotation which is parallel to the extension of the axis of rotation of the drum, that is, parallel to the radial direction of the drum. It is pivotally attached to the roller holding members 109 and 110. Stand holders 103 and 104 are integrally fixed to the roller holding members 109 and 110, respectively. The stand receivers 103 and 104 move integrally with the roller holding members 109 and 110, respectively. Each of the stand mounts 103 and 104 is a cylindrical member having a cavity inside. Pintle stands 101 and 102 having drum holding pintles 116 and 117 each having a diameter smaller than the rotary shaft hole of the drum are inserted into the stand receiving bases 103 and 104, respectively, and fixed by thumbscrews 105 and 106. Has been done.

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

In this case, first, the drum 118 is placed on the underrolls 201 and 202. Next, the thumbscrews 105 and 106 are loosened and the pintle stands 101 and 102 are slid up and down, and fixed at the positions where the pintles 116 and 117 face the rotary shaft hole 120 of the drum 118. Next, in order to engage the rotary shaft hole 120 of the drum 118 with the pintles 116 and 117, 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. Along with the rotation of the presser roller moving screw 111, the roller holding members 109 and 110 that are screwed into the screw are moved. At this time, since the screw portions 112 and 113 are cut at the same pitch in the opposite directions, the roller holding members 109 and 110 move in opposite directions by the same amount. As a result, the drum 118 engages with the pintles 116 and 117 while being rotatable around the rotary shaft hole 120.

When the cable is wound around the drum 118 in this state, the under rolls 201 and 202 are rotationally driven by a motor (not shown). The drum 118 rotates due to friction with the underrolls 201 and 202, and the cable is wound around the drum 118. At this time, since the drum 118 is rotatably engaged with the pintles 116 and 117, it is prevented from floating. Further, even if the drum 118 tries to shift in the rotation axis direction, the drum pressing rollers 107 and 108 prevent the shift. Therefore, a good winding operation can be performed.

Next, the case where the cable is wound around the large-diameter drum 119 indicated by the alternate long and short dash line will be described. In this case, first, the thumb screws 105 and 106 are loosened to remove the pintle stands 101 and 102, and then the drum 119 is placed on the underrolls 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 underrolls 201 and 202 are rotationally driven by a motor (not shown). The drum 118 rotates due to friction with the underrolls 201 and 202, and the cable is wound around the drum 118. At this time, since the weight of the large-diameter drum 119 itself is heavy, the winding operation is performed without lifting the drum 119. Further, even if the drum 119 tries to shift in the rotational axis direction, it is prevented by the drum pressing rollers 107 and 108.

In the present embodiment, the roller holding members 109 and 110 are moved by using the pressing roller moving screw 111 that is screwed with the roller holding members 109 and 110. However, the roller holding members 109 and 110 can be moved by simply sliding them. It is also possible to Further, the pintle stands 101, 102 are held on the stand mounts 103, 104 by the thumbscrews 105, 106. It is also possible to change the height of the hands 101 and 102.

Further, in the case of the large diameter drum 119, the pintle stands 101 and 102 are detached, but the pintle stands 101 and 102 are placed so that the pintles 116 and 117 are directed in the opposite direction to the drum 119. The pintles 116 and 117 may be made unobtrusive by making them rotatable with respect to the pedestals 103 and 104. Further, the pintle stands 101 and 102 may be movable so that the pintles 116 and 117 are positioned higher than the top of the drum 119.

As described above, according to the cable winding device of the present embodiment, it is possible to perform stable winding without the drum rising from the underroll. Further, the winding operation can be performed regardless of the diameter of the drum. Further, since the roller holding members 109 and 110 move in the opposite directions by the same distance from each other, even if the size of the drum changes, the center position of the drum is desired to change, so that good winding operation is possible. ..
