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, reels, etc. However, relatively thick and rigid filaments are Since they cannot be wound onto drums or reels, such filaments are wound into coils and accumulated on the ground or on floor stands.

By the way, this work of removing coils from the filament body is carried out by a large number of workers while pulling the filament body around by hand, but such a manual method involves many dangers. This is not desirable from the standpoint of safety management, 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. 25697, 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 supplied from above the device is slid on the slide to the ground or A coil removal machine has been proposed in which the length of a cylinder that rotates horizontally as it retracts toward the floor table is substantially changed according to the winding diameter of the coil removal. Although it is possible to mechanize the coil removal work, this device still has the following problems that need to be improved.

That is, in this device, the cylinder arm, which is equipped with a slide for guiding the filamentous body toward the ground or a floor table, is forcibly driven to rotate in a horizontal plane. It is difficult to coordinate the amount of retraction and the accumulated amount of the filament to be coiled. In other words, it is difficult to coordinate the amount of coiling and the amount of accumulated filament to be coiled. 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 is large in diameter and heavy. Due to the large rigidity and frictional force of the linear body, there is a risk that it will not be able to move smoothly, and furthermore, because the slide is fixed at a fixed angle of inclination,
The inclination angle of the slide does not match the folding and falling angle of the filament which changes depending on the winding diameter of the coil take-up, and this may hinder the smooth folding and falling of the filament. As a result, it has become extremely difficult to carry out normal coil winding work.

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 removal device is provided which allows the coil to be rotated in a driven manner and applies a forced retraction force to the filament using a retraction drive head provided on the rotating beam to easily and reliably perform coil removal 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 is as follows:
A support shaft 1 is installed vertically at the center of the storage, a rotating beam 2 is attached to the support shaft 1 so as to be able to rise and fall freely, and to rotate horizontally around the support shaft 1; A traveling frame 3 is attached so as to be able to move back and forth along its length.
and a retracting drive head 4 which is swingably supported by the traveling frame 3 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. In addition, this support shaft 1 includes
As shown in the figure, it has a guide roller 7a running along the guide rail 6, and the support shaft 1.
An elevating tube 7 that is raised and lowered by an elevator 8 such as a chain block provided at the upper end of the tube is fitted therein.

Near both upper and lower ends of the outer surface of this elevator tube 7,
Annular support plates 9 are provided, through which the rotating beam 2 is mounted 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, and the upper surface of the support plate 9 of the elevator tube 7 is attached to these support frames 2a. Alternatively, a plurality of support rollers 10 are provided that are brought into contact with the lower surface. These support rollers 10 support the rotary beam 2 on the elevating cylinder 7, and roll the surface of the support plate 9 in the circumferential direction to smoothly rotate the rotary beam 2 in the horizontal direction. It's becoming like that.

Further, each of the support frames 2a is provided with a plurality of positioning rollers 11 that contact the peripheral end surface of the support plate 9 to horizontally position the support frame 2a and the elevator cylinder 7. The space between the frame 2a and the elevating tube 7 is maintained to allow the rotating beam 2 to rotate smoothly.

Further, at the lower part of the rotating beam 2, two running rails 2b are provided which are parallel in a horizontal plane from the middle part where the support frame 2a is provided to one end. A traveling frame 3 is attached.

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 mounted. This drive motor 13 is engaged with a chain 14 stretched along the length below the rotating beam 2 via the chain sprocket 13a, and cooperates with the chain 14 to move the traveling frame. 3 is made to run in the length direction of the rotating beam 2.

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 along the length direction of the rotating beam 2. A rotating frame 16 is provided, which is swingable in a vertical plane around a connecting pin 15 extending in the horizontal direction.
includes a pair of retraction guide rollers 1 that can rotate in a vertical plane about a rotation axis extending in the horizontal direction.
7 is provided. One of these retraction guide rollers 17 is connected to a motor 18 attached to the rotating frame 16 and is driven and rotated thereby, and the other one is connected to a link provided on the rotating frame 16. It is fixed at 19. 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. It can be adjusted as appropriate depending on the wire diameter of the filament body C.

Furthermore, 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 pair of guide rollers 21 rotate in a vertical plane like the retraction guide rollers 17. One of the guide rollers 21 is movable along a long hole 22 provided in the rotating frame 16, and the distance between it and the other guide roller 21 is adjusted by the line of the filament C. It can be adjusted according to the diameter.

Further, between the feed-in guide roller 17 and the guide roller 21, a presser roller 23 that is rotatable about an axis that is perpendicular to the rotational axis of each of the rollers 17 and 21 and extends in a substantially horizontal direction is provided with a spacing maintaining leg. 24 to the rotating frame 16, so that the filament C is always positioned opposite the circumferential surface of the guide roller 17.

The retraction drive head 4 is the fifth
As shown by the chain lines in the figure and FIG.
7 and between the lower guide rollers 21, and the drawing-in guide rollers 17 are rotationally driven to apply a drawing-in force toward the lower part of the rotating beam 2 to the linear body C.

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. 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 holing device H 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 each pair of guide rollers 21 is moved to adjust the interval between the opposing guide rollers 21 in accordance with the diameter of the filament C, and the adjustment bolt 20 is operated to adjust the pair of retraction guides. The linear body C is held between the rollers 17 and the work is started.

And the striatum C from the hauling device H
At the same time, when the feeding guide roller 17 of the feeding drive head 4 is driven to rotate, a forced downward feeding force is applied to the filament body C, and the filament body C is successively moved onto the accumulation surface B. It is being laid down. Initially, the striatum C is guided so as to slide on the storage surface B, but as the amount of renormalization increases, the storage surface B of the striatum C
When the length of contact (frictional force) exceeds a certain level, the sliding movement stops, and the filament C is elastically curved between the retraction drive head 4 and the accumulation surface B (see D in Fig. 1). (see section) occurs.

When this bending phenomenon occurs, the filament C tries to return to its original state by its own elastic force, and the elastic restoring force acts on the rotating beam 2 via the folding drive head 4 as a rotational moment. At this time, since the rotating beam 2 is rotatably supported by the support shaft 1, it starts rotating in the horizontal direction as shown by arrow A in FIG. 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 sequentially spirals onto the accumulation surface B. It's going to fall. 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 to adjust the retraction drive head. 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, when the coil is being removed from the outside to the inside, the retraction drive head 4 is moved in the direction of arrow RO in FIG. 1 for each turn.

As the retraction driving head 4 moves along the length direction of the rotary beam 2 in this manner, the feeding inclination angle of the filament C fed from the holer H toward the retraction driving head 4 gradually changes. Since the retraction drive head 4 is swingably supported in a plane perpendicular to the running frame 3, the retraction drive head 4 swings in accordance with the change in the supply inclination angle, and as a result, the linear body C is easily dropped onto the accumulation surface B. Therefore,
No matter where the retraction drive head 4 is located in the longitudinal direction of the rotating beam 2, the striated body C can be smoothly retracted and dropped to the correct position on the storage surface B, and in this way, the striated body C can be It is accumulated in a coil shape on one plane. When stacking coils in multiple stages, the above-described operations may be repeated while the rotating beam 2 is raised and lowered in the direction of the arrow C in FIG. 1 using the lifting device 8.

Note that when carrying out the present invention, the elevator 8, drive motors 13, 18, etc. can be easily remotely controlled by wireless, wired, etc.

The wire coil coiling device of the present invention explained above has the following features:
It has the following excellent effects:

(a) The rotating beam can be raised and lowered freely on a vertically installed support shaft.
In particular, since it is attached so that it can freely rotate in the horizontal direction, the rotating beam will naturally form a linear shape due to the elastic restoring force generated in the curved linear part between this and the storage surface. As a result, the accumulated amount of the filament and the rotation of the rotating beam are always automatically synchronized, and as a result, it is possible to reliably eliminate the possibility that the filament will be disordered.

(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, even a large diameter and heavy filament can be easily retracted. It can be run.

(c) Since the retraction drive head is swingable in the vertical plane, even if the supply inclination angle of the wire 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.

Because of the synergistic effects of (a) to (c) described above, the filament can always be coiled in an orderly manner.
