Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rod winding device for winding a required amount of pipes and other wire rods and binding several peripheral portions to take out the wire rod bundles.

[0002]

1 and 2 show an embodiment of the present invention.
Except for the wire rod guide tube 11 and its accessories, it belongs to the prior art, and therefore the prior art will be described. The wire rod coil 1 is horizontally placed at the right end of FIGS. The wire rod (pipe) P that has been pulled out is directed toward the winding device 3 via the dancer roller 2. The operator directly sent the wire rod P coming out of the final feed roller 4 between the inner and outer guide tubes 5 and 6 of the winding device 3 with his or her hand. 1 and 2, the inner guide cylinder 5 is shown in a pulled-up state, but when it is wound up, it falls and enters the central portion of the outer guide cylinder 6 (see FIGS. 2 and 4).

The base plate 3a of the winding device 3 and the outer guide cylinder 6 placed on the base plate 3a are cut at three places, and after the standard length winding is completed, the wire bundle is bound at each of the dividing positions. Meanwhile, the inner guide tube 5 is retracted to the position shown in FIG. 1 of FIG.
Is a binding device. The motor 8 in FIG. 2 rotates the base plate 3a of the winding device 3. The rotation speed is adjusted to the feed speed of the feed roller 4. After bundling, the retracted inner guide cylinder 5 is lowered into the wire bundle, and the internal link mechanism is hydraulically driven to push out the peripheral wall of the guide cylinder 5 divided into three to hold the wire bundle and raise it. , A state-of-the-art prior art in which the wire bundle is moved down along the rail 9 and dropped onto the carry-out conveyor 10.

[0004]

The winding posture of the wire bundle winding device is horizontal, and the fed wire rod has a first stage so as to be spread on the rotating base plate 3a and between the inner and outer guide cylinders 5 and 6. Roll, stack the second layer on top, and the third layer on top. When the first step starts near the inner guide tube 5, it reaches the outer guide tube 6 and the first step ends. Then, the second step starts after being wound along the outer guide tube 6 and reaches the inner guide tube 5 to end the second step. Such reciprocal winding work is impossible without the help of the eyes and hands of the worker, and automation of this part has been abandoned. However, the present inventor has taken this as a development issue.

[0005]

In the wire bundle winding device of the present invention, the required amount of wire is wound between the inner and outer guide cylinders whose vertical peripheral wall is divided at 3 to 4 places, and is bundled at the divided places. In the wire bundle winding device for taking out, the sent wire rod is received at the inlet, and the wire rod guide pipe that is output from the outlet opened between the inner and outer guide cylinders, and the position closer to the inlet than the center of gravity of the wire rod guide pipe,
It is characterized in that it is provided with a guide tube shaft supporting portion which is supported by a horizontal shaft so as to be vertically swingable, and a floating rotary table which is supported so as to be horizontally rotatable on which the guide tube shaft supporting portion is mounted. Further, a spring for urging the wire guide tube is further provided, and the spring is provided so as to urge the outlet of the guide tube in a direction away from the inner and outer guide tubes.

[0006]

According to the research, the base plate 3a and the outer guide tube 6 of the wire bundle winding device are rotated according to the feed speed of the wire, and the wire is fed between the inner and outer guide cylinders so that the wire moves laterally. I found that if it was left free, it would naturally wind up in a spiral shape. Based on this, according to the present invention, a wire guide tube is newly installed so that even a flexible hose can be moved to a desired position between the inner and outer guide tubes without being bent, and at the same time, the wire can be pushed down lightly. That is, the guide tube shaft support is provided closer to the inlet than the center of gravity of the wire guide tube, the guide tube is supported so as to be vertically swingable, and the outlet side is pushed down by gravity. Since the guide tube shaft support is placed on a floating rotary table that can be horizontally rotated, the wire rod is automatically wound and the guide tube is automatically horizontally rotated.

When the first step is spirally wound in this way, it hits the wall surface of the guide tube, so that it rides on the final portion of the first step and starts winding the second step. The second lap rarely rides right above the first lap of the second tier, and since most of them slide down to the side of the first lap and line up, the second tier winds up side by side. However, in order to more surely cause the second stage to wind in the reversing direction, when the guide tube outlet is close to the wall of the guide tube, a spring is added to lightly bias the wall of the guide tube away from the wall. This spring bias can completely prevent the second lap from riding on the first lap of the second stage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 3 and 4 are explanatory views of the main parts of FIGS. In FIG. 3, the inner guide tube 5 is omitted. The wire guide tube 11 of FIGS. 3 and 4 is drawn as a simple tube to make it easier to see in FIGS. 1 and 2 are more suitable for pushing down the wire P by gravity, the embodiment is free. The outlet 11a of the guide tube 11 enters the gap between the inner and outer guide cylinders 5 and 6 and is pushed down by gravity. The wire rod P coming from the feed roller 4 of FIGS. 1 and 2 enters the guide tube inlet 11b via the pair of guide rollers 12. A guide tube shaft support 13 near the inlet 11b supports the guide tube 11 so as to be vertically swingable, and it is mounted on a floating turntable 14. The turntable 14 is horizontally rotatably mounted on a support frame 16 via a ball bearing 15. Therefore, the guide tube outlet 11a freely swivels horizontally around the center of the turntable 14 and can also swing vertically.

The wire rod guide tube 11 is provided with a coil spring 17 extending to the left and right, and its outlet 11a is lightly urged so as to move away from the inner and outer guide cylinders 5 and 6. This is because when the spirally wound wire rod reaches the guide tube 5 or 6 and is piled up, the guide tube 11 is lightly pushed or pulled so as to be wound in the opposite direction thereafter. Therefore, the spring force is adjusted by an experiment. . The spring 17 may be attached to only one side of the wire rod guide tube 11 as shown in FIG. 1, and may be urged back and forth by both pushing and pulling. It should be noted that the wire rod guide tube 11 near the inner and outer guide cylinders 5 and 6 is somewhat hindered from being horizontally rotated in the winding progress direction by the biasing force of the spring 17 while the winding of each stage is in progress. However, since the biasing force of the spring 17 is weak, it does not reach the force of the guide rod 11 being driven by the guide rod 11 itself when the guide rod 11 is laid down in a spiral shape while restraining the guide rod.

If the thickness of the bundle of wire rods, which is a product, is not so large, the outlet 1 of the wire rod guide tube 11 is vertically rotated.
The wire rod can be continuously fed to the uppermost stage by gradually increasing 1a.
However, in this embodiment, the support frame 16 that supports the floating rotary table 14 moves up and down so that the wire rods can be wound without any problem, no matter how thick the wire rod bundle is. That is, the wire rod guide tube 11
The supporting frame 16 on which is mounted is continuously or continuously wound during the wire winding operation by a screw driving mechanism (not shown) by a motor in the elevating and lowering driving unit 18 below and a base frame 19 having a column that also serves as an elevating and lowering rail. I try to go up intermittently. Even if the ascending speed and the increase in the winding height of the wire do not match, the wire guide tube 1
There is no problem because 1 swings vertically. Although one embodiment has been described above, the present invention does not change the gist thereof,
Needless to say, the wire rod guide tube and the floating rotary table should be varied depending on the designer.

EFFECTS OF THE INVENTION Among the operations for winding a hose and other wire rods to produce a fixed-length wire bundle, only the work of horizontally winding the wire rods has not been automated, but it is not suitable for precise computer control. , Because it was impossible to think of an automated facility that was cheaper than human labor. As a result of an analysis study of the horizontal winding work, this invention passes a flexible wire rod through a wire rod guide pipe and surely sends it to a required position, and at the same time, pushes down the wire rod by its own weight, and further, the guide pipe is held vertically. By supporting it so that it can swing and rotate horizontally, it is possible to automatically advance it. It was demonstrated that in order to more reliably reverse and wind the coil, when the guide tube outlet reaches either the inner or outer guide cylinder, the spring should be lightly biased in the direction in which the outlet separates from the guide cylinder.
