Description

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

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. 13738/1983.) In such a pipe yarn conveyance/delivery device, the pipe yarn detached from the pipe conveyor is not securely held by the inclined conveyor and falls, falling off the inclined conveyor and further falling outside. may fall. Further, in order to prevent the pipe from falling to the outside, guides are provided at the joints of the pipe conveyor and the inclined conveyor. However, due to the presence of this guide, the pipe yarn from the subsequent pipe thread transport conveyor can become jammed at the joint between the pipe thread transport conveyor and the inclined conveyor. In addition, the pegs attached to the yarn conveyor may fall off due to loosened screws, or if they are made of plastic, they may be damaged, and the yarn may be placed in the area where such pegs have fallen off or been damaged. Then, when the yarn is transferred from the yarn conveyor to the inclined conveyor, the yarn may similarly fall from the joint between the conveyor and the inclined conveyor to the outside. Furthermore, if a guide is provided as described above, the joint may become clogged with the tube yarn.

As mentioned above, it is not preferable in terms of production control to leave the pipe yarn that has fallen to the outside as it is. In addition, if a large amount of such pipe threads becomes clogged at the joints of the pipe transport conveyor and the inclined conveyor, normal transport of the pipe threads will no longer be possible, and in some cases, the pressing force caused by the clogged pipe threads may increase. This can cause damage to the pipe conveyor, which is often made of steel, and cause it to become severely distorted, rendering it unfit for further use.

The present invention aims to reduce problems in production management by early detecting falling of a pipe and yarn from a joint between a pipe and yarn transport conveyor and an inclined conveyor. The present invention has achieved such an object by providing a pipe thread conveyor in which a large number of pipe thread attachment pegs are protruded at predetermined intervals, and a pipe thread conveyor disposed downstream of the pipe thread transport conveyor so as to be inclined upward. In a yarn conveyance and delivery device comprising an inclined conveyor that receives and conveys the yarn conveyed by the yarn conveyor and detached from the yarn attachment peg, a yarn conveyor is provided along the inclined conveyor within the yarn transfer area between the two conveyors. A pipe yarn conveying and delivering device characterized in that a guide plate is provided for regulating both sides of the pipe, and a means for detecting a pipe falling from the transfer area to the outside is provided on the outer side of one of the guide plates. and achieve it. According to a preferred embodiment of the present invention, the guide plate on the side where the detection means is provided is provided with an opening whose edge height is substantially lower than the diameter of the full yarn, so that jamming in the transfer area is prevented. The tube is configured to actively fall through the opening. With the structure of this embodiment, if the pipe thread becomes clogged for some reason at the joint between the pipe transport conveyor and the inclined conveyor, the following pipe thread is discharged from the opening. Therefore, by providing the falling pipe yarn detection member of the present invention facing this opening, it is possible to detect clogging at the joint portion of the pipe conveyor and the inclined conveyor based on the presence of the falling pipe yarn. Note that only an alarm may be issued when clogging is detected, or the drive of the yarn conveying and delivering device may be stopped together with or separately from the alarm.

Embodiments of the present invention will be described below with reference to the accompanying drawings. A pipe yarn conveyor 1 is provided along a machine base such as a spinning machine and a twisting machine. The pipe yarn conveyor 1 includes a drive pulley 3 connected to an electric motor (not shown), a driven pulley (not shown) arranged along the machine base, and a tensioned drive pulley 3 and the driven pulley. It consists of a conveyor belt 5 extending horizontally along. The conveyor belt 5 is made of steel or the like, and plastic or metal pegs 7 are screwed or glued at predetermined intervals. When the conveyor belt 5 is positioned at a predetermined position, the pegs 7 are attached to the machine spindle ( (not shown). 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 consists of a driving pulley (not shown) driven by a motor (not shown), a driven pulley 13, and an inclined conveyor belt 15 stretched between the driving pulley and the driven pulley 13 and extending to the upper right. There is. 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.

The above configuration is the same as the device described in Japanese Utility Model Publication No. 13738/1982, and operates as follows. spinning machine,
As shown in FIG. 2, the full-pipe yarn P doffed from a twisting machine or the like by, for example, a simultaneous pipe changer moves to the right as the drive pulley 3 of the pipe yarn conveyor 1 rotates in the direction of arrow A. will be moved.

Immediately before the drive pulley 3, the upper end of the full yarn P hits the contact member 31. On the other hand, the pipe conveyor conveyor 1
As the conveyor belt 5 continues to move, the head of the full-tube 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. As the conveyor belt 5 further advances, the pegs 7 sink downward through the gaps 35a between the detachment claws 35, as shown in FIG. The full yarn P detached from the peg 7 is guided along the circumferential surface of the detachment pawl 35 (FIG. 2), reaches the inclined conveyor 11, and reaches the locking protrusion 1.
7 and is moved upward.

After being detached from the peg 7 of the yarn transport conveyor 1, the full yarn P moves not only parallel to the plane of the paper in FIGS. It may also move in the direction of Leaving the fallen yarn unattended in this way poses problems in terms of production management, in terms of accurately grasping the production quantity, and in maintaining an orderly working environment. Therefore, a member such as a limit switch, a phototube, or the like may be provided to detect the falling of the fully-tubed yarn, and an alarm may be issued to notify the operator when the fully-tubed yarn falls.

By the way, conventionally, in order to prevent falling as described above, guide plates 41 are provided on both sides of the inclined conveyor 11 in parallel with the machine base (see the chain line in FIG. 1). (Sometimes the machine stand wall can be used as a substitute.) By installing such a guide plate 41, it was possible to prevent the full yarn P from falling. However, if the full yarn P transferred from the yarn conveyor 1 to the inclined conveyor 11 is not locked by the locking protrusion 17, or if the peg 7 of the yarn conveyor 1 is chipped or damaged, the detachment claw 35 When the delivery is not carried out smoothly, the full tube yarn P may become clogged inside the guide plate 41. Such clogging may cause damage to the full yarn P or damage to the yarn conveyor 1 or the inclined conveyor 11.

Therefore, in this embodiment, as shown in FIG.
In addition, in the space of the yarn transfer area surrounded by both guide plates 41, an opening 41a shown by a solid line is formed by cutting the edge of one guide plate 41 so that the height is substantially smaller than the diameter of the full tube. is formed. However, if the opening is simply provided, the full yarn P will be transferred from the yarn conveying conveyor 1 to the inclined conveyor 1 as in the case where the guide plate 41 is not provided at all.
1, there remains a possibility that the full tube yarn P will climb over the edge and fall from the opening 41a due to a disturbance in its posture. Therefore, a bobbin guide 43 is provided above the opening 41a, and the peg 7 is secured by the release claw 35.
The head of the full tube yarn P removed from the tube is guided so that the full tube yarn P is guided to the inclined conveyor 11 without falling. Although the bobbin guide 43 shown in FIG. 1 is screwed to the guide plate 41, the bobbin guide 43 may be formed integrally with the guide plate 41.

Further, a member for detecting a falling pipe thread, such as a limit switch 51 or a phototube (not shown), is provided on the outside of the opening 41a.

Now, in the pipe yarn conveying and delivery device of this embodiment configured as described above, even if the full pipe yarn P gets clogged in the inclined conveyor 11 section for some reason, the following full pipe yarn P will overflow and be discharged to the outside from the opening 41a. be done. Therefore, damage to the pipe conveyor 1 or the inclined conveyor 11 is prevented. In addition, in this embodiment, the guide plate 41 has a special shape, so that if the pipe becomes clogged at the joint between the pipe and thread transport conveyor and the inclined conveyor, the pipe will move through the opening 41.
a, and is reliably detected by a falling pipe yarn detection member installed facing this opening. In other words, by quickly detecting the occurrence of clogging at the joint and issuing an alarm or stopping the yarn transporting and delivering device as necessary, damage to the yarn transporting and delivering device can be prevented.
