Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coil take-up device for winding a long filament, such as an electric wire cable, which has flexibility but relatively high rigidity into a coil. .

Generally, flexible long filaments such as electric wires and cables are wound up and stored on drums or reels. Since the filament cannot be wound onto a reel or a reel, such filaments are wound into a coil and accumulated on the ground or on a floor stand.

By the way, this work of removing coils from the filament is carried out by a large number of workers manually pulling the filament around, but this method of relying on manual labor involves many dangers, so there is no safety management. This is not preferable from the viewpoint of the above, and there is a problem that the work itself becomes impossible if the radius of the coil removal and the amount of accumulation (height of the pile) become large.

In order to solve these problems, conventionally,
As seen in Publication No. 97, a slide is attached at a predetermined angle of inclination to the tip of a cylinder that is forcibly rotated in a horizontal plane, and a filament body supplied from above the device is slid on the slide and placed on the ground or on a floor stand. A coil removing machine has been proposed in which the length of a cylinder that retracts upward and rotates horizontally is substantially changed according to the winding diameter of the coil. Although it can be mechanized, this device still has the following problems that need to be improved.

In other words, in this device, the cylinder arm, which is equipped with a slide for guiding the filamentous body towards the ground or the floor table, is forcibly driven to rotate in a horizontal plane. It is difficult to coordinate the renormalization base with the accumulated amount of the filament to be coiled, which means that the traveling speed of the filament and the movement of the cylinder arm are required to correctly drop the filament to the predetermined radial position where the coil should be taken. It is difficult to operate in synchronization with the rotational speed, and as a result, the synchronization between the running speed and the rotational speed may be disrupted, resulting in gaps between the coils or protrusion of the coils. In the retraction guide section, the filament simply slides down on a slide, and no active retraction force is applied to the filament, so it is difficult to remove this type of coil, which has a large diameter and is heavy. Due to the large rigidity and frictional force of the sliding filament, there is a risk that it will not be able to move smoothly due to its large rigidity and friction.Furthermore, since the slide is fixed at a fixed angle of inclination, the winding of the coil take-up is difficult. The inclination angle of the slide does not match the folding and falling angle of the filament, which changes depending on the diameter, and this may hinder the smooth folding and falling of the filament. This made winding work extremely difficult.

The present invention has been made in view of the above-mentioned points, and uses a horizontally rotatable beam attached to a vertical support shaft to respond to the movement of a filament that is spirally dropped from above to below. A coil removing device is provided that follows the coiling beam and rotates it in a driven manner, and applies a forced drawing force to the filament body using a drawing drive head provided on the rotating beam, thereby easily and reliably carrying out coiling in a predetermined pattern. This is what we provide.

The present invention will be explained below based on an embodiment shown in the drawings.

As shown in FIG. 1, the overall structure of the coil removing device according to the present invention includes a support @ 1 installed vertically at the center of accumulation of the filament C to be coiled, and a support @ 1 that can be freely raised and lowered on this support shaft 1. A rotating beam 2 is attached to the rotary beam 2 so as to be rotatable in the horizontal direction about the support shaft 1, a traveling frame 3 is attached to the rotating beam 2 so as to be movable back and forth along its length, and the traveling frame 3 and a retracting drive head 4 which is swingably supported in a vertical plane and applies a forcible retracting force to the filament C to be coiled.

The support shaft 1 is vertically supported on a base 5 installed on an accumulation surface B such as the ground where the filament C is coiled, and has a plurality of guides on its outer surface. A rail 6 is provided over the entire length. The support shaft 1 also has the guide rail 6 as shown in FIGS. 2 and 3.
It has a guide roller 7a that runs along the support shaft 1, and is fitted with an elevator tube 7 that is raised and lowered by an elevator 8 such as a chain block provided at the upper end of the support shaft 1.

Annular support plates 9 are provided near both upper and lower ends of the outer surface of the elevating tube 7, and the rotary beam 2 is attached via these support plates 9 so as to be freely rotatable in the horizontal direction.

A support frame 2a is provided at the intermediate portion in the length direction of the rotating beam 2 so as to surround the elevator tube 7. A plurality of support rollers 1o are provided that are brought into contact with the upper or lower surface of the plate 9. These support rollers 1o support the rotary beam 2 on the elevating cylinder 7, and are rolled in the circumferential direction on the surface of the support plate 9 to smoothly rotate the rotary beam 2 in the horizontal direction. It is meant to be done.

Further, the support frame 2a- is provided with a plurality of positioning rollers 11 which contact the peripheral end surface of the support plate 9 and position the support frame 2a and the elevator cylinder 7 in the horizontal direction. The interval between the frame 2a and the elevating cylinder 7 is maintained to allow the rotating beam 2 to rotate smoothly.

Further, at the bottom of the rotating beam 2, the supporting frame 2a is provided.
Two running rails 2b are provided which are parallel to each other in a horizontal plane from the middle part where the rails are formed to one end, and the running frame 3 is attached to these running rails 2b.

As shown in FIG. 4, this running frame 3 is suspended below the rotating beam 2 via running rollers 12 that engage with the running rail 2b and roll in the longitudinal direction thereof. , a drive motor 13 with a chain sprocket 13a is attached. This drive motor 1
3 is engaged via the chain sprocket 13a to a chain 14 stretched lengthwise below the rotating beam 2, and cooperates with the chain 14 to move the traveling frame 3 onto the rotating beam 2. It is designed to run in the length direction.

As shown in FIGS. 4 to 6, the retraction drive head 4 is connected to the traveling frame 3 via a connecting pin 15 and is rotatable along a vertical plane extending in the length direction of the rotating beam 2. In other words, the rotating frame 16 is provided with a rotary frame 16 that can freely swing in a vertical plane around a connecting bin 15 that extends in the horizontal direction. A pair of rotatable retraction guide rollers 1
7 is provided. These renormalization guide rows 517
One of them is the motor 1 attached to the rotating frame 16.
8 and is driven and rotated thereby, and the other one is fixed to a link 19 provided on the rotation frame 16. This link 19 is rotatable in a vertical plane about a pivot point at its upper end, and by appropriately adjusting its inclination angle with an adjustment bolt 20, the distance between the pair of retraction guide rollers 17 can be adjusted in a straight line. It can be adjusted appropriately according to the wire diameter of the body C.

Moreover, a pair of guide rollers 21 are provided above and below the pair of retraction guide rollers 17 of the rotating frame 16, and each rotates in a vertical plane like the retraction guide rollers 17. One of the pair of guide rollers 21 is movable along a long hole 22 provided in the rotating frame 16, and the other guide roller 21
The distance between the two can be adjusted according to the wire diameter of the filament C.

Furthermore, the above-mentioned retraction guide roller 17 and guide roller 52
1, a presser roller 23 that is rotatable about an axis extending substantially horizontally and perpendicular to the rotational axis of each roller 17.21 is connected to the rotating frame 16 via a spacing leg 24. As a result, the filament C is always positioned opposite to the circumferential surface of the kneading guide roller 17.

The retraction drive head 4 inserts the linear body C between the upper guide rollers 21, the 17 retraction guide rollers, and the lower guide roller 21, as shown by the chain lines in FIGS. 5 and 6. At the same time, the retracting guide row 517 is rotationally driven to apply a retracting force to the filament C toward the lower side of the rotating member 2.

On the other hand, what is indicated by the symbol H in FIG. It is dropped into the drive head 4 while rotating spirally.

In order to remove the coil from the filament C using the coil removing device configured as described above, first, the rotating beam 2 is lowered to the lowest position as shown by the solid line in FIG. It is moved to a position near the tip of the rotating beam 2.

Next, after inserting the tip of the filament C supplied from the holer MH between the guide rollers 21 of the retraction drive head 4, between the presser roller 23 and the rotation frame 16, and between the retraction guide rollers 17, One of the six pairs of guide rollers 21 is moved to face the guide rollers 21
The distance between the two is adjusted in accordance with the diameter of the filament C, and the adjustment bolt 20 is operated to sandwich the filament C between the pair of guide rollers 17 to start work.

Then, when the feeding of the filamentous body C from the holing device H is started, and at the same time, the carriage guide roller 17 of the carriage drive head 4 is driven to rotate, a forced downward force is applied to the filamentous body C. striatum C
are sequentially laid down on the accumulation surface B. and striatum C
is initially routed so as to slide on the accumulation surface B, but as the amount of renormalization increases, the accumulation surface B of the striatum C increases.
When the contact length (frictional force and length of contact with the ) occurs.

When this bending phenomenon occurs, the filament C tries to return to its original state due to its own elastic force, and the elastic restoring force acts on the rotating beam 2 via the retraction drive head 4 as a rotational moment. At this time, since the rotating beam 2 is rotatably supported by the support shaft 1, this is the first
Start rotating in the horizontal direction as shown by arrow A) in the figure. As the rotating beam 2 rotates in this way, the elastic force of the filament C gradually decreases and approaches zero, but since the filament C is continuously retracted from above, The elastic force does not completely disappear, and thus a rotational moment continues to act on the rotating beam 2, causing the rotating beam 2 to rotate continuously, so that the filament C moves toward the accumulation surface B.
Falling upwards in a spiral pattern. When taking the coil of the filament C, the winding diameter of the coil changes for each loop (one turn) of the coil, so the drive motor 13 is operated in accordance with this, and the drive head is retracted. 4 is moved together with the traveling frame 3 toward the rotation center side or the tip side of the rotating beam 2. For example, if the coil is being removed from the outside to the inside, the retraction drive head 4 is moved in the direction indicated by the arrow (b) in Fig. 1 for each winding.
move in the direction.

As the retraction drive head 4 moves along the length direction of the rotary beam 2 in this manner, the supply inclination angle of the filament C fed from the hole device H toward the retraction drive head 4 gradually changes. Since the feeding drive head 4 is swingably supported in a plane perpendicular to the traveling frame 3, the feeding drive head 4 swings following the change in the supply inclination angle, and as a result, the linear body C is easily dropped onto the accumulation surface B. Therefore, at which position in the longitudinal direction of the rotating beam 2 is the retraction drive head 4 located?
Even in the case where the filament C is placed on the storage surface B, the filament C can be smoothly drawn and dropped to the correct position on the storage surface B, and in this way the filament C is correctly accumulated in a coil shape on one plane. When stacking coils in a plurality of stages, the above-described operation may be repeated while the rotating beam 2 is raised and lowered in the direction of arrow (c) in FIG. 1 using the arm support device 8.

Note that when implementing the present invention, the elevator 8 and the drive motor 13
．． 18 etc., these can be easily remotely controlled by wireless, wired, etc.

The wire coil coiling device of the present invention described above has the following excellent effects.

(b) Since the rotating beam is attached to the vertical support shaft so that it can move up and down, and especially freely rotate in the horizontal direction, elastic The restoring force causes the rotating beam to rotate spontaneously in a linear manner, so that the accumulated amount of the striatum and the rotation of the rotating beam are always automatically synchronized, and as a result, there is no possibility that the striatum will become disordered. can be definitely excluded.

(b) Since the traveling frame attached to the rotating beam is equipped with a retracting drive head that applies a forcible retracting force to the filament, it is possible to easily retract even a large diameter and heavy filament. It can be run.

(c) Since the retraction drive head is swingable in the vertical plane, even if the supply inclination angle of the filament body fed toward it changes depending on the winding diameter of the coil, this The folding angle of the filamentous body toward the storage surface is automatically adjusted in response to the change, so that the filamentous body can be smoothly and effortlessly dropped into the correct position on the storage surface.

Due to the synergistic effect of the above-mentioned (a) to c), the filament can always be coiled in an orderly manner.
