Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a yarn winding and conveying system.

[Conventional technology]

Spun yarn produced by a spinning frame, especially a ring spinning frame, is wound into a certain shape on a rod-shaped core called a bobbin, and the spinning bobbin, which has a layer of yarn doffed from the spinning frame, is transported to a winder. the specified amount of thread,
The yarn is rewound to the desired shape while removing the defective yarn portions.

In such a case, in a small-variety, high-volume production system, the spinning bobbins doffed by the spinning machine are stored randomly or orderly in a bobbin box, and when conveyed to the winder, the yarn end preparation device on the winder side After being transferred into the winding unit and subjected to yarn end processing, the yarn is supplied to a bobbin storage magazine provided in the winding unit by means of conveyance means such as a conveyor or a trolley.

On the other hand, in a high-mix, low-volume production system, a so-called spinning winder that directly connects a spinning machine and a winder is installed, and the spinning bobbins doffed by the spinning machine are placed on a bobbin transport conveyor arranged along the spinning machine. There is a system in which the bobbin is inserted into an upright peg and transferred to the winder, transferred onto the bobbin transport medium on the winder installed adjacent to the spinning frame, and transported and supplied to each winding unit. be.

For example, in the spinning winder disclosed in Japanese Patent Application Laid-Open No. 59-163268, the spinning bobbin on the transport band on the spinning machine side is delivered from one end of the transport band to the winder side, and is kept waiting on the winder side. Each bobbin is transferred onto a transport medium called a tray, into which the bobbins are individually inserted, and then supplied to each winding unit.

[Problem that the invention seeks to solve]

In each of the above-mentioned conveyance systems, the spinning bobbin doffed by the spinning machine is simply a yarn layer wound onto the spinning bobbin, and in this state, the yarn layer portion is directly transferred onto the conveyor. If the bobbin is placed and transported, or if the bobbin is transported upright, it must be inserted onto a separate transport medium called a tray as described above.

That is, it is necessary to insert bobbins between the spinning bobbins and the conveyance medium that conveys the bobbins individually and to separate empty bobbins, and therefore there is a possibility that errors in insertion and separation may occur. occurs.

The present invention provides an extremely simple winding and conveying system, unlike the conventional bobbin conveying system described above.

[Means to solve the problem]

The present invention has a winding member that serves as a winding core when winding a yarn, and a conveying surface formed at one end of the winding member, and transports the yarn wound on the winding member to the next process. A spool is formed by integrally forming a spool with a conveyance member, and the spool is directly inserted into the spindle of a spinning machine to wind the yarn, and the spool is directly supplied to the rewinding position of the winder. It was designed to do so.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a state in which a thread body 1 is inserted into a spindle 3 of a spinning machine 2 and a thread Y is being wound thereon. That is, the winding body 1 includes a pipe-shaped winding member 4 that serves as a winding core when winding the thread, and a disc-shaped transport member 5 that is placed on a conveyor during transport after doffing. The winding member 4 is integrally made of synthetic resin plastic or the like, and in the case of this embodiment, a center hole 6 is formed in the winding member 4 passing through the center.

A large number of the spindles 3 are arranged side by side at equal pitches along the spinning machine table 2, and the spindles 3 are rotated by a drive belt 7. Reference numeral 8 denotes a ring traveler, which is raised and lowered by a known means (not shown), and can be moved above the winding body 1 during doffing, and carries the winding body in a fully wound state (hereinafter referred to as the actual winding body). It shall be moved to a position where it will not become an obstacle to extraction from the spindle 3.

Since the spool 1 is directly inserted into the spindle of a spinning machine to wind the yarn, the diameter D of the conveying member 5, which is the maximum diameter portion of the spool, is determined by the pitch between adjacent spindles, as shown in the second figure. The value is smaller than P. That is, at least a gap S is created between the thread bodies 1 and 1a to prevent adjacent conveyance members 5 and 5a from coming into contact with each other during rotation.

An example of a yarn conveyance system using such a thread body 1 is shown in FIG. A spinning winder is shown in which a ring spinning machine 2 in which a large number of spindles are arranged side by side and an automatic winder 9 are connected by a thread conveyance path. A belt conveyor 10 is laid around the spinning frame 2 along the spindle to form a conveyance path for the wound yarn. On the winder side, a transport path 11 for the fully wound yarn body and a return path 12 for the empty wound yarn body are formed along the winding unit constituting the winder, and are connected to the spinning machine side transport path via connecting paths 13 and 14. Directly connected. Therefore,
The actual yarn body wound with spun yarn produced by the spinning machine 2 is transferred on the conveyor 10 in the direction of the arrow 15, transferred to the winder side conveyance path 11, and conveyed.
It is supplied to the winding unit disclosed in Japanese Patent Application Laid-Open No. 57-141362.

The empty spool that has been rewound in the winding unit is discharged onto the return path 12 and transported in the direction of the arrow 16, and then returned to the spinning machine side transport path 1.
Returned above 0. In addition, the winding unit, which is unsplicable and is discharged with residual yarn, is once stored in the bypass path 18 from the return path 12 via the branch path 17, and after being repaired, it is branched again. It is transferred from path 19 onto conveyance path 11 heading in the direction of arrow 20.

The empty spool is conveyed to conveyor 1 on the spinning machine side.
When the yarn bodies are lined up and waiting on the spinning machine stand during winding, they are replaced with a fully wound yarn body on the spindle. Generally, in a spinning machine, doffing is performed by a simultaneous automatic doffing device, and therefore the empty yarn bodies on the conveyor 10 need to be lined up and waiting at a pitch equal to the spindle pitch.

In this embodiment, since the conveying member 5 for the spool 1 is a disk body with a diameter D smaller than the spindle pitch P, the spool 1 is transported on the conveyor 10 in a state where adjacent conveying members are in contact with each other. I guess I waited,
The difference between the dimensions P and D accumulates, making it impossible to doff all at once using an automatic doffing device. In addition, chuck pieces for gripping the bobbin of the known automatic doffing device are also provided in a number equal to the number of spindles and with a pitch equal to the spindle pitch.

That is, the relationship between the spindle pitch P and the diameter D of the conveying member 5, that is, the pitch D of the thread body is shown in FIG. Now, suppose that the center of the empty thread body 1a at the beginning coincides with the spindle center 3a,
Assuming that the following thread bodies 1b to 1n are stopped by a stopper (not shown) and are aligned one after another by coming into contact with the thread body, the center of the thread body and the center of the spindle into which the thread body is inserted are The deviation amounts l1 to ln gradually increase.

Therefore, an alignment device 21 is provided for aligning the thread bodies 1a to 1n at a pitch equal to the spindle pitch P. The device may, for example,
A position regulating plate 23 having a pitch between a and 22b equal to the spindle pitch P is provided along the conveyor 10, and the regulating plate 23 is moved toward the spool body in the direction indicated by the arrow 24.
The driving mechanism 25 shown in FIG. 3 moves parallel in the direction.

That is, by moving the regulating plate 23 in the direction of the arrow 24, both slopes 26 and 27 forming the trough 22 come into contact with the outer circumferential surface of the disc-shaped conveying member 5 of the thread body 1, thereby producing an alignment effect. As a result, the thread bodies 1a to 1n on the conveyor 10 are arranged at a pitch equal to the spindle pitch P, as shown in FIG.

In FIG. 3, as a drive mechanism for the regulation plate 23,
Although a case using the fluid cylinder 25 has been shown, it is of course possible to apply other various lever cam mechanisms, rack and pinion mechanisms, etc. Note that the conveyor 10 is
As shown in the figure, it is a flat belt conveyor, and the guide plate 28
The winding body 1 is placed on the flat belt 10 and is transported along the guide plates 29 and 30 on both sides.

As shown in FIG. 4, such a regulating plate 23 is divided and arranged at a plurality of locations along the spinning machine side conveyance path 10.

Therefore, with the above-described winding body alignment device, empty winding bodies are aligned and waiting at the spindle pitch on the conveyance path 10 on the spinning machine side, and are separated from the fully wound winding bodies on the spindle. The replacement work, that is, the doffing operation is performed. For example, by means of a chuck provided by a spindle on a frame extending over the length of one row on one side of a spinning machine, first all the empty spools on the transport path are chucked all at once, and once the empty spools are The empty winding body is moved away from the belt and the empty winding body is lowered to a temporary standby position provided on the spinning machine table side.Then, the frame is appropriately moved to grip the real winding body on the spindle, and the above-mentioned At the same time as it is pulled out from the spindle, the gripped actual wound yarn body is placed on the conveyor. At this time, in a normal ring spinning machine, bunch winding is applied to one end of the bobbin, and the thread is not continuous between the spindle and the bobbin on the conveyance path. The thread is doffed in a continuous state between the thread bodies on the conveyance path, and the continuous thread is cut at an appropriate position, and a suction airflow is introduced into the center hole of the thread body (Fig. 1, 6). By inserting the yarn end into the center hole 6 and conveying it in a hanging state, the step of taking out the yarn end on the winder side can be omitted.

Further, the chuck piece grips the empty winding body in the temporary standby position and inserts it into the empty spindle, thereby completing one cycle of the doffing operation.

In this way, the doffed actual thread body B is placed in the second
As shown in the figure, the paper is transported on the transport path 10 in the direction of arrow 20, and is carried into the winder.

In addition, when doffing as a wound yarn body subjected to normal bunch winding, the above-mentioned bunch winding is released,
A yarn end pulling device 31 is installed.

As described above, the thread wound onto the winding member 4 of the thread body is placed on the conveyor 10 by the conveying member 5 formed on the thread body itself, and remains in an upright state. Each book is transported independently and transported to the winder without being transferred to another transport medium.

〔Effect of the invention〕

In the present invention, a thread body in which a transport medium member is integrally formed on the thread winding member itself is directly inserted into a spinning spindle to wind the thread, and the actual thread body is simply placed on a flat belt conveyor. It can be transported to the winder side just by placing it there, and also in the winder, the yarn layer portion and the transport medium can be transported without combining or separating, which simplifies the transport process.
