~ Weft package delivery stations P1 to P6 for delivering the weft package W to the package transport vehicle V traveling back and forth along the supply lines T1 to T6 arranged above A6 (note that weft package delivery stations in general are referred to. In this case, a “weft package delivery station P” is simply arranged. R1 to R6 are rails (hereinafter, simply referred to as “rail R” when the general blower cleaner is referred to) for reciprocating travel of the blow cleaner arranged above each loom row A1 to A6. S (indicated by a circle in FIG. 1) is each loom a of each loom row A1 to A6.
1 to a6 are weft package stands, and B is a blow cleaner described later. In the above description, depending on the product type,
Although the case where the weft packages W1 to W3 are arranged in the weft package pool G is shown, an identifier for identifying the type of weft is attached to the bobbin of the weft package W or the weft package holder H suspended on the circulation line C. By attaching the weft packages W1 to W3, the weft packages W1 to W3 can be randomly accumulated in the weft package pool G.

FIG. 3 is a schematic front view of the weft package transfer system to the loom (the rails R1 to R6 for the reciprocating travel of the blow cleaner B are omitted), and the weft package holder as described above. The H is configured to hang around the circulation line C and circulate. Appropriate wheels v1 to v3 are arranged on the package transport vehicle V that travels back and forth on the ceiling along the supply line T. Also, a weft package gripping member v4 that holds the weft package W and a liftable bobbin holding member v5 that holds an empty bobbin are suspended on the package transport vehicle V. The lifting means for the weft package gripping member v4 and the empty bobbin gripping member v5 can be constituted by, for example, a winch mechanism or the like driven by a motor capable of rotating in the forward and reverse directions.

The weft package stand S holds weft packages W1 to W3 of different yarn types, and the weft package W1 is provided with a spare weft package W1 '. The yarn end and the winding start yarn end of the spare weft package W1 'are connected. Similarly, a spare weft package W2 ′ is arranged in the weft package W2, and a spare weft package W3 ′ is arranged in the weft package W3. For example, if the weft yarn package W1 in which the weft yarns supplied to the loom a are unloaded,
Subsequently, the weft is configured to be supplied from the spare weft package W1 '. The weft package W1
5 becomes empty, the supporting ring s1 of the empty weft package stand S, which will be described later, is rotated by an appropriate means, and the weft package holder s3 is swung, so that FIG. The empty bobbin is configured to face upward just below the supply line T, as shown in FIG.

In this way, when it is detected that one of the weft packages W1 and W1 'of the predetermined weft package stand S is empty, for example, by rotating the support ring s1 of the weft package stand S, etc. In accordance with a command from an appropriate control device, a weft package transfer device, which will be described later, delivers a predetermined weft package W from a weft package holder H that is suspended and moving on a circulation line C to a weft package delivery station P, and a weft package delivery station P. At the delivery station P, the attitude of the weft package W is controlled so that the weft package gripping member v4 of the package transport vehicle V can easily grip the weft package W.

Next, the weft package gripping member v4 of the package carrier V is lowered to grip the weft package W on the weft package transfer station P, grip the weft package W, and then raise the weft package gripping member v4. , The package transport vehicle V is run to a predetermined loom a. After stopping the package transport vehicle V above a predetermined loom a so that the empty bobbin holding member v5 is positioned on the empty bobbin facing upward, the empty bobbin holding member v5 of the package transport vehicle V is lowered to lower the weft. Package stand S
The upper empty bobbin is gripped, and after the empty bobbin is gripped, the empty bobbin gripping member v5 is raised. Next, the package transport vehicle V is slightly moved so that the weft package gripping member v4 is positioned on the weft package holder s3 from which the empty bobbin has been removed, and then the weft package gripping member v4 gripping the weft package W. Is lowered to hold the weft package W on the weft package holder s3 such as a predetermined peg of the weft package stand S, then the weft package gripping member v4 is raised, and the package transport vehicle V is again held.
To the weft package delivery station P. At the weft package delivering station P, the empty bobbin holding member v5 holding the empty bobbin is lowered to release the held empty bobbin on the chute P ', and the empty bobbin is accommodated in the empty bobbin collection box D or the like. .

Through the above steps, the weft package W is supplied to the weft package stand S of the loom a, which requires the weft package W, and the empty bobbin is recovered. The empty weft package holder H goes around the circulation line C and receives the weft package W of the same kind as the weft package W supplied to the loom a at the connecting portion with the weft package pool G.

By the way, when the weft package W is supplied to the predetermined weft package holder s3 of the weft package stand S as described above, the light s2 placed at the tip of the weft package stand S by an appropriate detecting means. Is lit to inform the operator that the preparation for connection between the winding start yarn end of the spare weft package W and the winding end yarn end of the weft package W that is supplying the weft yarn to the loom a is completed. In the weft package stand S in which the light s2 is turned on, the worker starts the winding start yarn end of the weft package W supplied as a spare weft package and the winding end yarn of the weft package W that is supplying the weft to the loom a. The end is connected and the light s2 is turned off when the connection is completed.

As a means for turning on the light s2 arranged at the tip of the weft package stand S, it is preferable to provide an appropriate switch for detecting that the weft package W has been inserted into the weft package holder s3. But,
The light s2 is turned on by disposing a proximity switch for detecting that the weft package gripping member v4 gripping the weft package W is lowered near the tip of the weft package holder s3 or the weft package stand S. You can also Also, the weft package gripping member v4
Alternatively, a signal may be emitted from the package transport vehicle V side in response to the downward movement of the light, and the light s2 may be turned on by the reception device arranged on the weft package stand S side.
A signal from the package carrier V is sent to the control device, and since this control device recognizes which weft package stand S to supply the weft package W, the desired light s2 is turned on by the command of this control device. You can also let it. According to the latter method, each weft package stand S
No need for sensors, etc.

In this way, the fact that the worker has supplied the spare weft package W to the weft package holder s3 of the weft package stand S is indicated by turning on the light s2 arranged at the tip of the weft package stand S. Since it is configured to notify, the connection between the winding start yarn end of the supplied weft package and the winding end yarn end of the weft package that is supplying the weft to the loom despite the supply of the spare weft package It is possible to solve the problem that the weft supply is stopped when the wefts of the weft package that are supplying the wefts to the loom run out. In the above embodiment, the notification is made by turning on the light s2 arranged at the tip of the weft package stand S, but the notification may be given by sound instead of turning on or blinking the light s2. .

The operational effects of the weft package transport system to which the present invention described above is applied will be listed below.
Supply lines T1 to T6, which are substantially linear in shape, are arranged above the respective weaving machine rows A1 to A6 in which the package transport vehicle V that supplies the weft packages W to the respective weaving machine rows A1 to A6 and travels back and forth. The weaving machine a, the weft package stand S, the supply line T or the circulation are provided by separately disposing the circulating line C around which a plurality of weft package holders H for receiving and containing the weft packages W from the weft package pool G are suspended. The degree of freedom in arranging the line C and the like is increased, and it is possible to design the layout of a loom or the like having good workability and excellent productivity. Moreover, according to this system, when the weft yarn packages W are requested by the two loom rows A at the same time, the weft yarn packages W can be quickly supplied.

Further, as in the conventional weft package conveying system in which an endless chain or the like is run above the loom row A to convey and supply the weft package W to each loom, the installation distance of the endless chain or the like is set. Since the number of supporting columns for the endless chain is reduced, the space can be efficiently used and the blow cleaner B or the like can be installed or run because the number of supporting columns for the endless chain is reduced. The route is not restricted. Further, compared with the conventional one, the traveling distance of the endless chain or the like is short, and the number of bent portions is small, so that the generation of noise is small and the working environment can be improved. The above-mentioned weft packages W1 to W3 may be the same type of weft packages, and the package transport vehicle V may be not only overhead traveling but also floor traveling.

A weft package transfer member p6 is attached, and a weft package transfer member p6 including a rod-shaped weft package receiving member p7 and a rod-shaped weft package receiving member p7, which is erected substantially vertically to the weft package mounting member p6. p9 is a conveyor arranged on the weft package delivery station P.

As shown in FIG. 4 (a), the drive shaft p2 is rotated by an appropriate driving means such as a motor to raise the weft package receiving member p3, and the weft package receiving member p3 is moved to the weft package holder H. The weft package W accommodated therein is lifted by advancing it through the space h1 (see the weft package holder H shown in FIG. 3) at the bottom of the package. By moving the circulation line C in this state, the weft package W is delivered to the weft package receiving member p3 as shown in FIG. 4 (b). Then, as shown in FIG. 4 (c), the weft package receiving member p3 is rotated 90 degrees and the drive shaft p2 is reversed to lower the weft package receiving member p3, as shown in FIG. 4 (d). As described above, the weft package W is delivered onto the weft package receiving members p7, 7'which are maintained substantially horizontal. Next, the weft package mounting member p8 is rotated so that the weft package mounting member p6 is substantially horizontal, and the weft package W is held substantially vertically as shown in FIG. 4 (e). , Move to traveling conveyor p9. With the above configuration, the weft package W accommodated in the weft package holder H in a substantially horizontal shape can be transferred onto the weft package delivery station P in a substantially vertical shape. In addition, when the weft package receiving member p3 moves up and down,
Instead of the drive shaft p2 in which the screw groove is engraved, a piston rod or the like driven by a fluid may be used, and the weft package transfer device is not limited to the above-mentioned various types and a robot or the like is applied. A weft package transfer device can be applied.

For reference, the blow cleaner B and the supply line T on which the package carrier V travels will be described with reference to FIG. 5, which is a schematic side view of the weft package transfer system to the loom a including the arrangement of the blow cleaner B. The arrangement relationship of will be described.
