Description

[Detailed Description of the Invention] The object of the present invention is to automatically replenish new winding thread when the winding thread supported by the creel runs out, and to simultaneously replenish a plurality of winding threads.

The winding thread insertion shafts of the creel are provided in many rows in the horizontal direction and in many steps in the vertical direction. Then, the two shafts protruding from the support rod are combined as a supply winding thread and a spare winding thread, and when the supply winding thread runs out, the support rod is rotated to supply the thread with the spare winding thread, and in the meantime, The winding thread is supplied to the creel by inserting a new winding thread through the shaft. Usually, the threads run out at about the same time in related threads, and therefore it is necessary to simultaneously rotate multiple support rods to supply threads to multiple rows of shafts in the lateral direction.

However, since the winding yarn has a considerable weight, even if it is easy to insert it into the shaft at a low position, it is difficult to feed it to a high position (about 2 m above the ground with a normal creel), and it is difficult for the operator to do so. There was a risk of injury and a lack of work efficiency.

Therefore, the present invention provides a winding yarn supplying device that increases work efficiency and ensures safety by simultaneously supplying winding yarn to a plurality of shafts at the same horizontal position.

An embodiment of the present invention will be described below based on the drawings.

1 is a frame whose width is multiple winding threads (5 in the drawing)
The height is higher than the highest axis of the creel, and the wheels 4, 4, 4, 4 of the movable body 3 engage with the guide rails 2, 2 provided on the front and rear surfaces of both side frames, and the movable body 3 is movable in the vertical direction.

A vertical piece 5 is integrally fixed to the movable body 3,
It is tied 9 to a chain 8 suspended from sprockets 6 and 7 that are pivotally supported on both sides of the frame.

Both upper sprockets 6 are fixed to the same drive shaft 10, and the worm gear 11 of the drive shaft 10
A worm 13 rotated by a vertical/reverse motor 12 is engaged with the worm 13. Since both the movable bodies 3, 3 are tied 9 to the chain 8 at the same horizontal position, the two movable bodies 3, 3 are moved up and down at the same speed and in the same direction by energizing the vertical/reverse motor 12.

In addition, a rotating rod 14 with a vertical groove 13 is provided on both sides of the frame.
is erected, and worm gears 15 and 16 are attached to the upper end of the rotating rod 14.

Worm gears 15 and 16 are worms 19 and 20 on a shaft 18 that is powered by a forward/reverse insertion motor 17.
It meshes with the Since the worms 19 and 20 are threaded in opposite directions, the worm gears 15 and 16 rotate in opposite left and right directions as the same drive shaft 18 rotates, so the left and right rotating rods 14 rotate at the same speed at the same time. Rotate backwards.

Furthermore, a shaft ring 23 which is integrally screwed to the arm rod 21 with screws 22 is loosely fitted into the rotary rod 14, and the shaft ring 23 is controlled by a key 24 that fits into the vertical groove 13 of the rotary rod 14 to control the upper and lower parts of the rotary rod. Although it slides in the direction, it is driven by the rotation of the rotation rod 14.

A connecting ring 26 screwed together with the movable body 3 by a bolt 25 is loosely inserted into the shaft ring 23 and is held between the upper and lower ends. Therefore, although the shaft ring 23 and the connecting ring 26 move together in the vertical direction, the connecting ring 26 is not affected by the rotation of the shaft ring 23.

27 is a bolt that fixes the arm rod 21, the shaft ring 23, and the key 24, and 28 is a screw ring that holds the connecting ring 26.

A substantially L-shaped supporting bent rod 29 is pivotally attached to the tip of the arm rod 21, and the tip of the supporting bent rod 29 forms an arcuate portion 30 having a center point at the bent portion.

Teeth 31 are carved on the arc surface of the arcuate portion 30, and the tip teeth 31 of the support curved rod 29 are pivotally attached to the left and right arm rods 21.
are configured to mesh with each other. Then, the winding yarn receiving plate 32 is placed on both supporting curved rods 29, 29 with the engagement line of the teeth 31 positioned on the center line, and the curved portion which is the center point of the tooth arc circumference and the bottom surface of the winding yarn receiving plate 32 are aligned. The supporting curved rods 29, 29 support the thread receiving plate 32 in a symmetrical manner about the center line of the thread receiving plate 32.

The winding thread receiving plate 32 has a recess 3 so that the winding thread 33 can be stably placed at a position corresponding to the interval between the winding shafts of the creel.
4 mag on the top surface.

The base of the arm rod 21 is centered on the rotation rod 14 for determining the position, and the support bent rod 29 is pivoted on the winding thread receiving plate 32 at the curved portion.
3, and furthermore, the teeth 31 at the tips of the support curved rods 29 mesh, and since the left and right support curved rods 29 are symmetrical at the meshing portion (the arm rods 21 are also symmetrical), the left and right arm rods are symmetrical. By the rotation of 21, the winding yarn receiving plate 3
2 moves in parallel in the front-back direction. At this time, the rotation range of the arm rod 21 is limited by the support curved rod 29, and since the orbit of the shaft attachment part of the support curved rod 29 with the arm lever 21 is fixed, Pivot support 3
3 as a fulcrum, but since the end teeth 31 of the left and right supporting curved rods 29 engage and rotate, the left and right supporting curved rods 29 are always symmetrical about the center line of the winding yarn receiving plate 32, and the winding yarn receiving plate 32 rotates. The plate 32 will move in parallel in the front-back direction.

Since the present invention has the above-mentioned configuration, the vertical/reverse motor 12 and the insertion/reverse motor 17 are operated to move the winding yarn receiving plate 32 below the frame 1 and on the side opposite to the creel replenishment shaft. Position (Figures 2 and 3)
(shown by the solid line in the figure), the winding thread 3 of the winding thread receiving plate 32
3 in the designated place. In this case, the thread receiving plate 32
Since it is located at a low position, the loading operation can be easily carried out.

Next, when the vertical/reverse motor 12 is rotated in the normal direction, the worm 13 and the worm gear 11 move the drive shaft 10
Since the sprocket 6 rotates, the movable body 3 rises together with the suspended chain 8. Since the guide rail 2 and the wheel body 4 are engaged during the ascent, the ascent of the movable body 3 is restricted in the vertical direction, and the shaft ring 23 is keyed to the vertical groove 13 of the rotation rod 14. There is no problem in vertical sliding.

When a predetermined height for yarn feeding is reached, the energization of the vertical/reverse motor 12 is cut off, and the energization of the insertion forward/reverse motor 17 is made to rotate in the forward direction, thereby causing the worms 15, 16 and worm gears 19, 20 to rotate. Then, the left and right rotating rods 14 rotate in a direction that rotates the arm rod 21 toward the creel, and the support curved rod 29 is also driven, causing the winding receiving plate 32 to move in parallel toward the front creel and winding the yarn around the creel shaft. 33 is inserted.

The rotating rod 14 and the shaft ring 23 are driven by the key 24 with respect to the rotation of the rotating rod 14, while the connecting ring 26, which is integral with the shaft ring 23 and the movable body, is in a loosely inserted state, so that it is not connected to the movable body 3. There is no problem.

After that, the winding thread receiving plate 32 is lowered a little, moved backward, and further lowered to return to the original position by rotating the up/down forward/reverse motor 12 and the insertion forward/reverse motor 17 in the opposite direction. This is to prepare for yarn feeding work.

As described above, the yarn feeding device of the present invention is very efficient because it can simultaneously insert a plurality of yarns into the creel shaft, and the yarn receiving plate 32 can be moved up and down, making it easier to place the yarn. It can be done easily. Then, the entire width of the winding receiving plate 32, which has a considerable weight due to a plurality of threads placed thereon, is received by the supporting bent rod 29,
Since the end teeth 31 of both rods 29 are in mesh with each other, they are integrated and increase the supporting force, and even when the winding yarn receiving plate 32 is moved back and forth, they remain in the meshed state according to the rotation of the support curved rod 29. Since it is located on the center line of the thread receiving plate 32, it does not reduce the supporting force, and also prevents slack from occurring in the center of the thread receiving plate 32 due to the weight of the thread. We can respond accurately.
