The diameter of the transferring member 5 is smaller than the pitch between the spindles 3. The yarn package after winding the spun yarn (Y) in the spinning machine 2 can be transferred to the winder side simply by placing the yarn package on a belt conveyer.

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 spinning machines, especially ring spinning machines, 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 machine, is transported to Waingoo. The yarn is then rewound to a predetermined amount and shape while removing defective yarn portions.

In such cases, in a low-mix, high-volume production system,
The spinning bobbins doffed by the spinning machine are stored in bobbin boxes randomly or in an orderly manner, and when they are transported to the wine goo side, they are transferred to the yarn end preparation device on the wine goo side where the yarn ends are processed. The bobbins are supplied to a bobbin storage magazine provided in the winding unit by a conveyor such as a conveyor or a cart.

On the other hand, in a high-mix, low-volume production system, a so-called spinning wine goo is installed that directly connects a spinning machine and a wine goo, 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 wine goo side, transferred onto the bobbin transport medium on the wine goo side installed adjacent to the spinning machine stand, and then transported and supplied to each winding unit. .

For example, in the spinning wine goo 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 wine goo side, and waits on the wine goo side. Each bobbin is transferred onto a conveying medium called a tray, into which each bobbin is independently 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 up, and at this point, 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. Therefore, there is a possibility that errors in insertion and separation may occur. arise.

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

[Means for Solving the Problems] 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 a winding member that is wound on the winding member. A conveying member for transporting the cut yarn to the next process is integrally constructed to form a spool, and the spool is directly inserted into the spindle of a spinning machine to wind the yarn. is supplied directly to the winding position of the wine goo.

〔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 vibrator-shaped winding member (4) that serves as a winding core when winding the thread, and a disc-shaped winding member (4) that is placed on a conveyor during transport after doffing. The member (5) is integrally made of synthetic resin plastic or the like, and in the case of this embodiment, the winding member (4) has a center hole (6) that passes through the center. There is.

A large number of the spindles (3) are arranged in parallel at equal pitches along the spinning frame table (2), and the spindles (3) are rotated by a drive belt (7).

(8) is a ring traveler, which can be raised and lowered by a known means (not shown), and can be moved above the winding body (1) during doffing, and is fully wound (hereinafter referred to as the actual winding body). ) from the spindle (3) to a position where it does not become an obstacle.

Since the spool (1) is directly inserted into the spindle of the spinning machine to wind the yarn, the diameter (D) of the conveying member (5), which is the largest diameter portion of the spool, is as shown in the second figure. The value is smaller than the pinch (P) between adjacent spindles. That is, there is at least a gap (S) between the thread bodies (1) and (la).
) occurs, and during rotation, the adjacent conveying member (5)
This is to prevent (5a) from coming into contact with each other.

FIG. 4 shows an example of a thread conveyance system using such a thread body (1). A spinning wine goo is shown in which a ring spinning machine (2) with a large number of spindles arranged side by side and an automatic wine goo (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 wine goo side, a conveyance path (1
1) and a return path (12) for the empty wound yarn body, which are directly connected to the spinning machine side conveyance path via connection paths (13) and (14). Therefore, the actual yarn body wound with spun yarn produced by the spinning machine (2) moves on the conveyor (10) as indicated by the arrow (
15) and is transferred to the wine goo side conveyance path (11).
The paper is transferred to, transported to, and supplied to a winding unit disclosed in Japanese Unexamined Patent Publication No. 57-141362.

The empty spool that has been rewound in the winding unit is discharged onto the return path (12) and shown in the direction of the arrow (16).
) direction, and is returned onto the spinning machine side conveyance path (10) again. In addition, the wound body that is discharged from the winding unit with remaining yarn that cannot be spliced goes from the return path (12) to the branch path (17) and then to the bypass path (1
8) and after being reworked, the conveyance path (1
1) Moved up.

The empty spools are lined up and waiting on the conveyor (10) on the spinning machine side, and when they are doffed on the spinning machine table during winding,
Replaced by a full spool on the spindle. Generally, in a spinning machine, doffing is performed by an automatic doffing device all at once, and therefore the empty yarn bodies on the conveyor (10) need to stand by in line at a pitch equal to the spindle pinch.

In this embodiment, since the conveying member (5) for the spool (1) is a disc body with a diameter (D) smaller than the spindle pitch (P), the spool (1) is transported on the conveyor (10). ) If the conveying members adjacent to each other are kept in contact with each other, the difference between the above-mentioned dimensions (P) and (D) will accumulate, making it impossible to doff all at once using the 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 with a pinch equal to the spindle pitch.

That is, the spindle pitch (P) and the conveying member (5
) with the diameter (D), that is, the pinch (D) of the spool, is shown in FIG. Now, let's assume that the empty spool at the beginning (
Assuming that the center of 1a) coincides with the spindle center (3a), it is stopped by a stopper (not shown), and the subsequent thread bodies (1b) to (1n) successively contact the thread body and are aligned. The amount of deviation (pl) to (βn) between the center of the thread body and the center of the spindle into which the thread body is inserted gradually increases.

Therefore, an alignment device (21) is provided to align the thread bodies (1a) to (In) at a pitch equal to the spindle pinch (P). The device can be used, for example, in a valley (2
2a) The pinch between (22b) is the spindle pinch (P
) is placed on the conveyor (
The drive mechanism (2) shown in FIG.
5).

That is, by moving the regulating plate (23) in the direction of the arrow (24), both slopes (26) (27) forming the valley (22) are formed.
comes into contact with the outer peripheral surface of the disc-shaped conveying member (5) of the spool (1), and an alignment effect occurs, so that the spools (1a) to 1 on the conveyor (10) as shown in FIG. (In) is aligned with a pinch equal to the spindle pinch (P).

Although FIG. 3 shows a case in which a fluid cylinder (25) is used as the drive mechanism for the regulation plate (23), other various lever cam mechanisms, rack and pinion mechanisms, etc. are of course applicable. The conveyor (10) is a flat belt conveyor as shown in Fig. 3, and runs on a guide plate (28), and the winding body (1) is placed on the flat belt (10), with guide plates on both sides. (29) Transported along (30).

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

Therefore, the above-described winding body alignment device allows empty winding bodies to be aligned and waiting on the conveyance path (10) on the spinning machine side at the spindle pitch, and to be aligned with the winding body on the fully wound spindle. A replacement operation, that is, a doffing operation is performed. For example, first, the empty spools on the conveyance path are chucked all at once by a chuck provided at a spindle pitch on a frame extending over the length of the rows on one side of the spinning machine, and once the empty spools are is moved away from the heald and the empty spool is lowered to a temporary standby position provided on the spinning machine table side. After this, the frame is appropriately moved to grip the real spool on the spindle, and At the same time, the gripped actual wound yarn body is placed on the conveyor. At this time, in a normal ring spinning machine, punch 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 created in 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 wine goo side is omitted.

Furthermore, the chuck piece grips the empty winding body in the temporary standby position and inserts it into the empty spindle, so that one part of the doffing operation can be carried out.
The cycle is complete.

In this way, the doffed actual yarn body (B) is conveyed on the conveyance path (10) in the direction of the arrow (20), as shown in FIG. 2, and is carried to the wine goo side.

In addition, when the above doffing is performed with normal punch winding and the yarn is doffed as a wound body, the punch winding is released and the yarn to be taken out is placed midway through the wine goo side conveyance path (11) in Fig. 4. An end outlet device (31) is installed.

As described above, the thread wound onto the winding member (4) of the thread body is placed on the conveyor (1o) by the conveying member (5) formed on the thread body itself. 1 in standing position
Each book is transported independently and transported to the wine goo 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 wine goo side just by placing it there, and also in the wine goo, it can be transported without combining or separating the thread layer portion and the transport medium, which simplifies the transport process.
