Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tubing yarn supplying device provided with a reservoir for aligning a large number of tubing yarns supplied to a parts feeder one by one and carrying them to the next step.

[0002]

2. Description of the Related Art Tubular yarn from a spinning machine is stored in a box, and a large amount of it is put into a circular parts feeder in order to convey the yarns one by one to a winder in the next process. In the parts feeder, the tube yarns are aligned one by one by vibration and are moved to the outer periphery, are transferred to the conveyor, and are carried out to the next step.

A reservoir is provided in the transfer unit, and after storing a predetermined amount, the necessary yarns are carried out from the chute and inserted into the tray which is conveyed to the tray for conveying the yarns to the next step. This reservoir is provided with a reserve part for each individual thread so that a predetermined number of packages can be stored, and this reserve part is sequentially fed by a drive device to discharge the stored thread, and the empty reserve part is fed from the parts feeder. They are sequentially stored on a conveyor that conveys the yarn.

Further, when the yarn on the conveyor is discharged, the parts feeder is driven so as to supply the yarn to the empty space on the conveyor, the yarn is transferred to the conveyor, and the driving of the parts feeder is stopped after the movement. To do.

[0005]

In the above-mentioned conventional apparatus, when the yarn stored in the reservoir is discharged to the tray, the reservoir is always driven in a fixed direction and is accommodated in the reserve portion which follows in the driving direction. Is discharged.

[0006] Therefore, it is sufficient that the reserve yarn is always stored in the subsequent reserve portion. However, when the discharge of the pipe yarn from the reservoir continues, the reserve yarn portion may not be stored in the reserve portion. The reservoir had to be driven until the reserved portion of the reservoir was located at the discharge portion.

Therefore, there is a drawback that it takes time to discharge the yarn from the reservoir, and eventually the movable time of the parts feeder for supplying the yarn to the reservoir is reduced, and the amount of the yarn supplied is reduced.

There is also a tilted popper for containing the yarn in order to continuously supply the yarn, but the yarns housed in the popper are in close contact with each other to form a block, which causes the yarn clogging. However, there is a problem in that the tube threads come into contact with each other and are easily fluffed or dirty.

Therefore, an object of the present invention is to improve the yarn feeding efficiency of a yarn feeding device having a reservoir.
