Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a winding device k for winding a filament such as a rope onto the entire winding drum, to prevent the filament from being irregularly wound around the winding drum due to the occurrence of slack in the filament. Regarding the irregular winding prevention device,
In particular, it is 51 on the body that is rolled up! After detecting the initial stage of the occurrence of A, the striatum is pressed against the winding drum directly by the device, and then the striatum is pressed against the winding drum by the device directly, and then This invention relates to a device for preventing irregular winding of a filament, which is characterized in that the filament is intermittently forcibly guided in the '1ain force direction of the winding drum by a predetermined signal during the winding.

Conventionally, in winding devices that wind filament bodies such as ropes onto winding drums, there are those that wind the filament in only one layer and wind the filament in several layers by providing a screw-like groove in the winding drum. In the case of a multi-layer winding method in which the rope is wound in the same manner, as the number of *7 and → increases, the winding becomes irregular, not only making it impossible to wind the rope for a long time, but also causing the rope to become loose and shorten the rope's lifespan significantly. In addition, in order to improve the above problem, there is a winding device that uses four diagonal grooves that are guided at non-uniform speeds according to the rotation of the flute cylinder, but the effect of the winding is reduced as the layers of the multi-layer winding grow. was also not sufficient.

Originally, as shown in Fig. 1, when moving from the rope fixed end 1 of the winding drum 4 to the second winding 9 position B, a space 2 corresponding to the jh diameter of the rope is created, so ideally If the rope is not guided by the diameter of the rope per rotation of the winding drum, but if the rope is guided by the diameter of the rope to IH+, which rotates by a distance corresponding to space 2 during one rotation of the winding drum. Usually, the rope guide should be stopped while the other winding drums are rotating.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and the purpose of this invention is to forcibly change the length of the wire body, that is, the last winding turn of the last stage of the rope, to the development view shown in Fig. 2 for one revolution of the winding drum. As shown, by providing a disorderly winding prevention device that includes a feeding device that forcibly guides the rope in the axial direction of the winding drum for a predetermined distance at a predetermined location to perform ideally aligned winding. be.

Another object of the invention is to take up the load state of the winding device;
In the case of unwinding, the alignment winding of the filament, that is, the rope, is achieved by providing the above-mentioned feeding device, but if a load such as a suspended load lands or the towed object stops, the winding drum may be delayed in stopping. As shown in Fig. 5, the rope that has been wound in an orderly manner around the winding drum becomes slack, which causes the rope to wind erratically during subsequent winding.In order to prevent this erratic winding,
The purpose of the rope pushing to push the rope in the direction of the winding drum is to provide an irregular winding prevention device a that prevents the device from winding.

Hereinafter, examples of the present invention will be described in detail with reference to the drawings. 6 and 4 show a rope winding neck equipped with a winding prevention device according to the invention.

In the winding device, the beginning of the rope 6 is fixed to the winding drum 4, the rope 6 is passed between a pair of guide rollers 15, 15 attached to the arm 14, and the other end of the rope 6 is connected to a load. There is.

In this state, the winding device pulls the load. The feeding device, which is part of the irregular winding prevention device in this winding device, will be explained. Guide bars 11 and 12 are fixed to a frame 9 placed on the bed 8, and a feed screw 13 is rotatably mounted on the frame 9 between the guide bars 11 and 12.

One end of the feed screw 13 is connected to a feed motor 22 attached to the frame 9, so that the feed screw 16 is rotated in forward and reverse directions by the motor 22. A slide 10 is attached to the pair of guide bars 11, 12 so as to be slidable in the axial direction, and an internal thread 24 that is threadedly engaged with the feed screw 16 is provided at the intermediate portion of the slide 10. Therefore, the slide 10 can slide in the axial direction according to the rotation of the feed motor 22. Next, the filament of the irregular winding prevention device in this winding device, that is, the rope pressing device 6, is connected to the rope pressing device 61. The arm 14 is rotatably attached to the slide 10 that

Next, the construction of the irregular winding prevention IF device according to the present invention IIq]
Explain and explain. As shown in Fig. 1 and the furnace, and Fig. 2, the low zero per rotation of the winding drum is 'N:fill.
In order to wind the winding device ff, a transmitting device, for example, a micro switch (not shown) is attached to one place on the inner periphery of the cylinder 4, and the winding device ff generates a signal every time the winding>+lT++ is rotated. 10, and in response to the signal, the feed motor 22 is rotated intermittently by 1'I "111". The feed screw 16 connected to the motor 22 rotates intermittently by the 1;41 interlocking of the motor 22, and the slide 10
The roller slides intermittently by a distance corresponding to the diameter of the roller depending on the rotation angle of the winding drum 4. By the way, slide 10v
The arm 14 which is pinched and loosely engaged with the guide bar 12
A pair of guide rollers 15 are rotatably attached to the holder, and when a load is applied to the rope passed between the pair of kite rollers 15, the rope 6 is pulled out by a tension spring 21.
And against its own weight, it becomes a straight line state 6' as shown by the dotted line, and the arm 14 and swing arm 16 are in a raised state as shown by number 23! In this state, the rope 6 is forcibly guided to the winding drum 4, as shown in FIGS. 1 and 2, and wound onto the winding drum 4 in alignment.

When the first row is finished winding and reaches the flange of the winding drum 4, the dog 26 or 28 comes into contact with the microswitch 25 or 29, the microswitch 25, 29 is activated, and the feed motor 22 is reversed. In the next stage, the row 76 is wound onto the winding drum 4 in the opposite direction. The swing arm 16 is swung relative to the arm 14 by a hinge pin 17, but this is for the purpose of further feeding the slide 10 even after the presser roller 20 has come into contact with the flange of the winding drum 4.

Next, when the suspended load lands or the side-pulling trolley coasts and slack occurs in the low zero, the arm 14 and the swing arm 1
6, that is, to attach the rope presser, the device K1 is lowered from the position indicated by the dotted line indicated by number 26 to the position indicated by the solid line indicated by number 30 by turning 1 around the guide bar 12 according to its own weight and the extension length (dimension 21). A presser roller 20 presses the roller in the direction of the winding drum 4.

As a result, it is possible to prevent the part taken up by the professional winding drum 4 from loosening, but the winding IJ can be prevented after the rope 6 is held down.
When the lIII 4 rotates in the direction in which the rope 6 is paid out, slack occurs. Due to C, the rope presser is placed at the dotted line position t14:' by pulling the rope, and the rope presser is placed in the state (actual position 60) from 2nd to 1jJ1. For example, a microswitch (not shown) is used as a device for outputting the kl- signal. As a result, the initial stage of slack in the rope 6 is detected, and the winding drum 4 is slightly reversed and stopped.

Since the above I'4 is achieved, no.9 is achieved during one rotation of the winding drum.
From a predetermined position, the rope is slid a predetermined distance from a predetermined rotational distance in the direction of the rope base to the winding wire for a predetermined distance, i.e., the rope diameter, and the rope is ideally placed on the winding drum. It can be made to align without any problem. Moreover, if the wire staking body, that is, the rope becomes slack, the rope presser is attached to the device I'
I can press the rope against the winding drum and prevent the rope from winding erratically during winding.
