Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a full bobbin wound up by a spinning machine (hereinafter referred to as a tubing) which is detachably attached to a peg of a peg tray, and the peg tray is transferred along the longitudinal direction of the machine base. The present invention relates to a tubing yarn conveying device adapted to pull out a tubing yarn from a peg at the machine base end.

[0002]

2. Description of the Related Art As a conventional yarn conveying device, for example, there is one disclosed in Japanese Patent Publication No. 63-53105.
This is to arrange the carrier rail around the entire circumference of the spinning machine, install a tray transfer device for horizontally transferring the peg tray along the carrier rail, and grip the pipe thread attached to the peg of the peg tray at the machine base end. Although it was equipped with a gripper mechanism that pulls it up by pulling it out, it is inefficient in the work of extracting the yarn from the gripper mechanism, and in addition, the equipment cost and energy saving are due to the fact that the gripper mechanism that requires some kind of drive source is provided. There was a problem that it was not desirable.

Therefore, as a tube yarn transporting device which does not use a gripper mechanism, the present applicant has filed Japanese Patent Application No. 7-216663.
This is because the transport rail is provided with a loop part on the side of the machine base end, a guide member is provided below the loop part, and the yarn is conveyed directly below the discharge port of this guide member. A box was provided, and when the pegs of the peg tray transferred through the loop portion faced downward, the yarn fell out under its own weight, and the fallen yarn was accommodated in the yarn transport box via the guide member. .

[0004]

In the above-mentioned conventional yarn conveying device, it is necessary to make the radius of curvature of the loop portion to a certain extent so that the peg tray can smoothly convey the loop portion. There is a problem that the space becomes large, and the total length of the transport rail becomes long, so that the number of peg trays to be guided becomes large.
Further, in the above-mentioned conventional device, the loop portion is provided on the side of the machine base end portion in order to minimize the installation space of the entire device, and the pipe thread transporter placed on the floor corresponding to the loop portion is conveyed. There was a problem that the box greatly protrudes on the passage between the adjacent spinning machines, which hinders the traveling of the passage.
Further, in the above-mentioned conventional device, a transport rail is arranged immediately below the loop part in order to minimize the installation space of the entire device, and the yarn transport box cannot be positioned immediately below the loop part, and the guide line is not provided. Although the tubular yarn is accommodated in the tubular yarn carrier box via the member, there is a problem that the surface of the tubular yarn is damaged by friction when being guided by the guide member.

[0005]

As described above, in the present application, the peg tray is horizontally transferred along the machine longitudinal direction with the peg facing upward, and the pegs are directed downward at the machine base end so that the pegs fall out. It is characterized in that the peg tray is twisted and guided around the carrying direction, and then the peg tray is twisted and guided around the carrying direction so as to bring the peg up again during horizontal transfer. Therefore, at the machine base end, the yarn can be pulled out from the peg to the center in the machine width direction by its own weight, and a device with a small installation space and a short length of the transport rail can be provided. The yarn can be delivered directly to another conveying means.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present application, the transport rail is provided with a twist guide portion for twisting and guiding the peg tray in the transport direction so that the peg faces downward at the machine base end, and the transport direction of the twist guide portion is set. On the downstream side, a return-twist guide portion for twisting and guiding the peg tray in the transport direction is provided so that the peg faces upward again during horizontal transfer. Therefore, since only the twist guide portion and the return twist guide portion are provided on the transport rail, it is possible to provide a yarn transfer device having a small installation space and a short total length of the transport rail.

Further, a pair of longitudinal conveyance rails extending in the machine longitudinal direction, a pair of machine width conveyance rails extending in the machine width direction, and one machine width conveyance rail arranged above the other conveyance rails. The transport rail is configured so as to surround the entire spinning machine with a connecting rail that connects with the longitudinal transport rail, and a twist guide portion is provided in the intermediate portion in the machine width direction of the one of the machine width transport rails, and the downstream side in the transport direction. The connecting rail is provided with a return twist guide portion. Therefore, the yarn from the peg can be pulled out from the peg at the center of the machine base in the machine width direction, and the yarn carrier box can be prevented from protruding in the machine width direction.

Further, the yarn thread transport box is provided directly below the twist guide portion. Therefore, it is possible to directly deliver the tubing that has fallen out of the peg to the tubing transport box and prevent the tubing from being damaged.

Since the mechanism for dropping the yarn 100 from the peg 31 by its own weight is configured, the installation space of the transport rail 3 can be made smaller than that of the conventional device in which the yarn dropping mechanism is configured by a loop portion having a large radius of curvature. In addition, the entire length of the transport rail 3 can be shortened.

Further, in the above embodiment, the twist guide portion 10
Is provided in the central portion of the machine-width conveying rail 3c in the machine-width direction, and there is a space between the machine-width conveying rail 3c and the floor surface. Since it is possible to prepare, the pipe thread transport box 40 does not extend to the side of the passage and become a hindrance to traveling as in the conventional case. Furthermore, the damage of the recovered yarn 100 can be suppressed as compared with the conventional device that collects the yarn 100 falling from the peg 31 into the yarn transport box via the guide member. Incidentally, in the above embodiment, all the transport rails 3
The adjacent peg trays 30 are brought into contact with each other to transmit the action of the tray transfer device 50. However, an endless transfer band that is in pressure contact with the peg tray 30 is provided on the connection rails 3d and 3e and the machine width transfer rail 3c. The peg trays 30 may be transferred without making contact with each other by the orbital movement of the band. Further, in the above-mentioned embodiment, the other yarn feeding means is the yarn transport box 40,
The present invention is not limited to this, and may be configured by a belt conveyor or the like, for example.
