Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a yarn conveying and delivering device. More specifically, the present invention relates to a device for doffing, for example, a simultaneous pipe changing device, and conveying and delivering full pipe yarn wound up in a spinning machine, a yarn twisting machine, etc.

2. Description of the Related Art Various pipe and thread conveyance and delivery devices including a pipe and thread transport conveyor and an inclined conveyor are known. In this case, the pipe yarn doffed from a spinning machine, a twisting machine, etc. is received on a pipe conveyor conveyor on which a large number of pegs for attaching the pipe yarn are protruded at predetermined intervals. transport along. An upwardly inclined inclined conveyor is provided downstream of the pipe thread transport conveyor, and receives and transports the pipe thread conveyed by the pipe thread transport conveyor and detached from the pipe thread mounting peg.
(For example, see Japanese Utility Model Publication No. 54-13738.) In such a pipe conveyance/delivery device, the pipe yarn detached from the pipe conveyor is not securely held on the inclined conveyor and falls down, which causes the subsequent pipe yarn to fall. The yarn from the conveyor can become stuck at the junction of the yarn conveyor and the inclined conveyor. When the tube is clogged in this way, it is no longer possible to carry the tube normally, and in some cases, the clogged tube may be damaged by the pressing force when the tube is clogged. This may cause the yarn conveyor to become severely distorted, making it unusable for further use.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device that prevents the pipe and yarn transferred from the pipe and yarn transport conveyor to the inclined conveyor from falling from the inclined conveyor and ensures that the pipe and yarn are transferred and delivered reliably. In the present invention,
This purpose is achieved by providing a first guide that deflects the tubular yarn that has been detached from the peg of the tubular yarn conveyor and is headed toward the inclined conveyor in a direction crossing the conveying direction; This is achieved by a pipe yarn conveyance and delivery device characterized in that a second guide that guides the pipe yarn to the inclined conveyor and a third guide that is arranged along the inclined conveyor and prevents the pipe yarn from falling from the inclined conveyor are arranged in combination. .

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, a pipe yarn conveyor 1 is provided along a spinning machine, a yarn twisting machine, or the like. The yarn transport conveyor 1 is suspended between a drive pulley 3 connected to an electric motor (not shown), a number of driven pulleys (not shown) arranged along the machine base, and the drive pulley 3 and the driven pulleys. It consists of a conveyor belt 5 extending horizontally along the machine base. The conveyor belt 5 is made of steel etc.
Plastic or metal pegs 7 are screwed or glued at predetermined intervals so that when the conveyor belt 5 is positioned in a predetermined position, the pegs 7 correspond to the spindles (not shown) of the machine base. There is. An inclined conveyor 11 is provided on the downstream side of the yarn transport conveyor 1, that is, on the right side in FIG. The inclined conveyor 11 includes a driving pulley (not shown) driven by a motor (not shown), a driven pulley 13, and an inclined conveyor belt 1 stretched between the driving pulley and the driven pulley 13 and extending to the upper right.
It consists of 5. On the circumferential surface of the inclined conveyor belt 15, locking protrusions 17 having wear resistance and appropriate flexibility are protruded at equal intervals.

Above the drive pulley 3 of the yarn transport conveyor 1, a contact member 31 made of an elastic material such as urethane rubber or a leaf spring supports a bracket 33, similar to the device described in Japanese Utility Model Publication No. 54-13738. It is attached to the machine base via. In addition, the inclined conveyor 11 is
Up to the circumferential surface of the driven pulley 13 of 13738
Similar to the device described in the publication, the release pawl 35 is extended. The detachment pawl 35 is for detaching the tube yarn from the peg 7 of the tube conveyor 1 and guiding it to the inclined conveyor 11, and is screwed to the machine base via a bracket 37.

A guide plate 41 is provided on the side surface of the joint between the pipe yarn transport conveyor 1 and the inclined conveyor 11 to guide the pipe yarn P detached from the peg 7 of the transport conveyor 1 to the inclined conveyor 11. 1st guide 4
3 is fixed to the guide plate 41. The first guide 43 is located at the head of the pipe P, and as best shown in FIG. A guide surface of the first guide 43 is provided to intersect with the first guide 43 (in the vertical direction in the figure). Thereby, the pipe yarn P is biased toward the machine stand 39 side along the guide surface. Second
The guide 47 has a guide surface 45 that is inclined in the opposite direction to the guide surface of the first guide 43 and biases the yarn in the opposite direction. The tube yarn biased in the opposite direction by the second guide 47 reaches a position on the back side of the first guide. Facing this back position, the third
A guide 49 is provided. The third guide 49 is fixed to the guide plate 41 by welding or the like, and is preferably connected to the first guide 43.

The embodiment of the invention described above operates as follows. As shown in FIG. 1, the full-pipe yarn P doffed from a spinning machine, a yarn-twisting machine, etc. by, for example, a simultaneous pipe changer is transferred as the drive pulley 3 of the pipe yarn conveyor 1 rotates in the direction of arrow A. Moved to the right.

Immediately in front of the drive pulley 3, the head of the full yarn P hits the abutment member 31. On the other hand, the pipe conveyor conveyor 1
As the conveyor belt 5 continues to move, the head of the full-length yarn P is pushed relatively backward from the abutment member 31 as shown in FIG.
The lower end of the front bobbin lifts up. In this state, peg 7
reaches the tip of the detachment claw 35, and therefore the detachment claw 3
5 is inserted between the lower end of the full tube yarn P and the conveyor belt 5. When the conveyor belt 5 further advances, the full yarn P rides on the detachment pawl 35, and therefore the full yarn P is completely separated from the peg 7. The full-tube yarn P detached from the peg 7 is guided along the circumferential surface of the detachment claw 35 (FIG. 1), and then further guided by the first guide 43.
As a result, as shown in FIG. 3, it is biased from the guide plate 41 side to the machine stand 39 side. Next, the biased pipe thread is passed through a second guide 47 attached to the machine stand 39.
It reaches the guide surface 45 of
Reach 5. The inclined conveyor 15 moves in the direction of arrow B, and the pipe yarn P is scooped up by the locking protrusion 17 and transferred. As described above, the first and second guides 43,
As a result of biasing the tube threads in opposite directions by 47,
The tube yarn is taken into a small space between the first guide 43 and the inclined conveyor 15. The small space is sufficiently small, there is no room for the tube yarn to change its posture significantly, and the tube yarn is prevented from falling off the inclined conveyor 15. Furthermore, in the present invention, since the third guide for preventing falling is provided opposite to the inclined conveyor 15, even if the head of the yarn tries to turn away from the inclined conveyor 15 for some reason, this is prevented.
Falling is reliably prevented.

In the above embodiment, the first and third guides are provided on the guide plate side, and the second guide is provided on the machine stand side. However, the first and third guides may be provided on the machine base side, and the second guide may be provided on the guide plate side.

According to the present invention, it is possible to prevent the pipe yarn from falling off the inclined conveyor, and it is possible to realize smooth delivery and conveyance of the pipe yarn from the pipe conveyor to the inclined conveyor. Further, by connecting the first and third guides as in the embodiment, the guide installation space can be reduced and the strength of these guides can be sufficiently increased.
