Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device in which continuously supplied yarns are fed or drawn by rollers and wound on a bobbin by a winding machine.

[0002]

2. Description of the Related Art In a conventional winding device, as shown in FIGS. 5 and 6, a frame 50 having a gate-shaped lower portion is built from the floor, and a winding machine 51 is arranged in the gate-shaped frame 50. A feed roller group 52 for heating and stretching or cooling the yarn to feed the yarn is installed at a position above the gate of the frame 50, and a nozzle (not shown) for discharging the yarn above the frame 50 and the above. The spinning cylinder 53 for cooling and solidifying the yarn was arranged. That is, the winder 51 and the feeding rollers 52 are separated from each other, and the feeding rollers 52 are arranged on a frame fixedly installed on the floor.

[0003]

According to such a conventional technique, the position of the yarn guide 54, which serves as a traverse fulcrum when the yarn is wound by the winding machine, becomes high. Therefore, the thread guide 5
The position of the feed roller installed further above 4 becomes higher, and the machine height of the equipment becomes higher (for example, in the case of an 8-end winder having a bobbin holder length of 1200 mm, the position of the feed roller 52a is set). Has a height of 3500 mm from the floor and a frame height of 4000 mm.) When a worker hooks a thread, a workbench is required, resulting in poor workability and low safety due to work in high places. There was a problem.

As described above, since the frame height is high,
There has been a problem that the construction cost of the equipment increases due to the reason that the frame of the winder and the building in which the winder is set up become large, and the foundation that supports the frame needs to be solid. Also, in order to install the feeding roller,
There was a problem that a large frame built from the floor was required and the equipment cost was high.

Since the equipment is high in height, it is not possible to sufficiently cope with an increase in the size of the winding package and an increase in the number of ends when performing scrap and build which is restricted by the building.

[0006]

SUMMARY OF THE INVENTION The object of the present invention is to solve the problems associated with the prior art as described above, and to reduce the height of equipment, the cost of equipment, the workability, and the safety. It is to provide a yarn winding device.
