Description

Detailed Description of the Invention a. OBJECT OF THE INVENTION [Industrial field of use] The present invention relates to a conveying device for automatically conveying a yarn supply package to a yarn spinning machine.

[Conventional technology]

Conventionally, an operator manually feeds the yarn supplying package to the yarn spinning machine, and there has been no automatic device.

[Problems to be Solved by the Invention]

It is an object of the present invention to provide a yarn feeding package conveying device that can automate the yarn feeding package conveyance in a yarn spinning machine.

B. Configuration of the Invention [Means for Solving the Problems] In order to achieve the above-mentioned object, a yarn feeding package conveying device in a yarn spinning machine of the present invention includes a unloading conveyor and a feeding conveyor along front and rear surfaces of a machine base. A conveyor is provided, and two side-by-side conveyors are provided side by side on each side of each weight, and a series of conveyors from the carry-out conveyor to the supply conveyor are tilted toward the front of the machine base. The conveyor at the front of the side is set to the winding position, and when the yarn feeding packages are received there, they are inclined downward with respect to the center of each other. Is performed by a swing arm that lowers and the rear end rises to a subsequent tray passage.

[Work]

In the yarn feeding package transporting device for the yarn twisting machine configured as described above, the two left and right yarn feeding packages carried in the conveyors in front of the respective weight side portions are in a state where both adjacent sides are lowered, and at that position. Being rolled up. When the yarn supply package is completely wound up, the empty tray is discharged to the carry-out conveyor, and the succeeding yarn supply packages are called in. The movement of these yarn supply packages is smoothly performed by the fact that a series of conveyors from the carry-out conveyor to the supply conveyor are inclined toward the front of the machine base and the action of the swing arm.

〔Example〕

Unlike the winder, the compound yarn machine has the following features.

1) Two yarn feeding packages are required for each spindle. In the future, three or four compound yarns are also considered.

2) It is necessary to tilt the two yarn supply packages downward with respect to their centers.

FIG. 6 (A) shows the yarn supplying packages which are inclined with respect to each other. FIG. 6 (B) shows the yarn supply packages arranged vertically. If the angles of the drawn yarn with respect to the center line are α and β, and the height l from the bottom of the yarn supplying package to the yarn guide is the same, α <β.

By the way, in order to increase the winding speed, it is necessary to reduce the yarn bending angle in the yarn guide. Since this yarn bending angle is also an angle with respect to the center line of the drawn yarn, it is advantageous that the yarn bending angle is α, that is, the yarn feeding package shown in FIG. Is.

3) Since the yarn winding machine uses two yarn feeding packages for each spindle, the pitch between the spindles is determined by the size of the yarn feeding package. For example, when a yarn feeding package having a package outer diameter of 220 mm and a peg tray outer diameter of 240 mm is used, the pitch between the weights is 510 mm. In addition, since it is necessary to convey the yarn supply packages with as close a space as possible, a swing arm type stopper that swings up and down is used as a stopper for controlling the feeding and stopping of the yarn supply packages.

With the above in mind, the yarn feeding package conveying device of the present invention has been developed, and the embodiments thereof will be described below with reference to the drawings.

The symbols A, B, C, D and E used in the respective drawings represent the position of the yarn spinning machine on the conveyor and also represent the yarn supplying package existing at that position.
