Abstract

PURPOSE:To aim at compactification in a conveying system, by installing a residual yarn remover in a conveying passage for the bobbin discharged out of a winder, and conveying the said bobbin to a fine spinning frame at once as an empty bobbin. CONSTITUTION:On the way to a conveying passage 21, there is provided with a branch passage 9 which feeds a pick finding device with a half-bundle bobbin again, and a residual yarn remover ST2 is installed on the way to the conveying passage 21 as well. A half-bundle bobbin selecting sensor is set up just in front of the branch passage 9, and the half-bundle bobbin alone is transferred onto a bypass 10. At the residual yarn remover ST2, a minim yarn remaining bobbin and an empty bobbin are discriminated, and the empty bobbin passes by as it is, then transferred to the side of a fine spinning frame 1, while the minim yarn remaining bobbin is removed of its remaining yarn, and on an empty bobbin conveying passage 27, only the tray fitted with the empty bobbin is present, thus it is transferred to the side of the fine spinning frame 1. Therefore, a new empty bobbin feeding station is no longer required so that a conveying system is simplifiable.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a bobbin conveying system.

[Conventional technology]

Bobbins produced by spinning machines, especially ring spinning machines, are discharged from the above-mentioned winders, and are either empty bobbins that have been completely wound and have no yarn layer, or are re-supplied to the winder with a large amount of yarn layer left behind. There are bobbins that can be used for half a thread, and even bobbins with a very small amount of yarn that cannot be re-supplied to the winder.These various bobbins are randomly discharged, and each bobbin is sorted and placed in a box. Either the bobbins are stored, or the half-bobbins are automatically transported to a pick-up device, where only empty bobbins and bobbins with very little remaining thread are separated and stored in a box, and the box containing the empty bobbins is transported to the spinning machine, and the bobbin with very little remaining thread is stored in a box. The box containing the bobbins is transported to a residual yarn removal work by a worker, and the empty bobbin from which the residual yarn has been removed by the worker is transported again to the spinning machine.

[Problem that the invention seeks to solve]

On the other hand, in spinning spinning machines suitable for high-mix, low-volume production, in which spinning machines and winders are connected via a bobbin conveyance path, there is no problem as long as a certain number of bobbins circulate through the spinning machines and winders, but as mentioned above, there is no problem. If only bobbins with thread are taken out and reworked, the number of bobbins being circulated will gradually decrease, and a new station for supplying empty bobbins will be required. A supply device is required, and multiple transport systems are required.

The present invention aims to solve the above problem.

[Means to solve the problem]

The present invention provides a residue removal device in the conveyance path of the bobbin discharged from the winder.

[Effect]

Among the bobbins discharged from the winder, the remaining yarn on the bobbin with residual yarn is removed at a residual yarn removal device position along the conveyance path, and the bobbin becomes an empty bobbin, which can be immediately conveyed to the spinning machine.

Next, the operation of the remaining yarn removing device will be explained.

This device operates in the order shown in Figs. 5, 6, and 7. First, the bobbin (B), which has been placed upright on the tray f22) and conveyed by the conveyor (33), is stopped by a stopper (not shown). It is temporarily stopped at a position directly below the present residual removal device shown in FIG.

When the stop is confirmed by a sensor etc., the operating rod (50)
is pushed down, the push contact piece rotates and releases its contact with the guide rail, and then the push contact piece ( 43) also rotates and separates from the guide rail 541.

As a result, the opening/closing member @8) (391 opens in the direction of Fig. 5(a) by the force of the spring, and the pressing piece (43)
Another cam surface of f44) comes into contact with the guide rail 541549 and stops.

After the opening/closing member t, as+ (39) is opened, the lifting rod (34) is lowered by a cylinder (not shown), and the upper end of the stopped bobbin (B) is inserted into the bobbin chuck work.

At this time, the roller 15263 descends along the guide groove (G) 6n and is stopped at the fifth illustrated position by a stopper (not shown).

The bobbin (B) contacts the side surface of the bobbin insertion hole σ9, which has a tapered tip, and gradually expands it, that is, rotates the chuck piece σeσυ in the direction of the arrow (b) in Fig. 9. With its upper end in contact with the lifting rod (disc part (8) 1 of 3-1), as shown in Fig. 10,

) is released from its stop and transferred to the next process by a conveyor (33).

Note that the residual thread removal device (STI) removes the remaining thread during the movement when the bobbin (B) is once removed from the tray and then reinserted into the tray.
Of course, it is also possible to use a device that removes the remaining yarn while the bobbin is inserted into the tray, and in this case, the device of the above embodiment (STI
) is provided with a pressing member that presses the upper end of the bobbin instead of the bobbin chuck, and a pair of opening/closing members! 3g) (

〔Effect of the invention〕

As described above, in the present invention, among the bobbins discharged from the winder, bobbins with residual yarn that cannot be resupplied to the winder are treated as empty bobbins with residual yarn removed by the residual yarn removal device installed in the conveyance path. Because it is conveyed, there is no need for workers to make any adjustments, and in a system that connects a winder and a spinning machine, conveyance is possible without removing all the bins with residue from the conveyance path, making it possible to make the conveyance system more compact, and to reduce empty space. There will be no excess or shortage of bobbins, and quantity control will be easier.
