Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a bobbin for transporting empty bobbins and full bobbins between a plurality of spinning machines and one or a plurality of winders using a peg tray having pegs protruding from the upper surface. The present invention relates to a full bobbin carrying method in a carrying system.

2. Description of the Related Art In general, a yarn produced by a spinning machine, particularly a ring spinning machine, is rewound by a winder into a package having a size and shape suitable for a subsequent process. In order to save labor and improve productivity, the spinning machine and the winder are directly connected to each other via a bobbin transfer path, and the full bobbin (tubular yarn) after the spinning machine is fed to the winder, and the empty bobbin after being used by the winder is spinning machine. Various spinning winders for transporting and supplying the same have been proposed (for example, Japanese Patent Laid-Open No. 60-67369, Japanese Patent Publication No. 1-27943, etc.).

When carrying full bobbins and empty bobbins between the spinning machine and the winder, the spinning machine supplies the full bobbin in response to a full bobbin request signal from the winder. Therefore, it is necessary to send and receive signals between different types of machines, which are a spinning machine and a winder. In the case of a fine spinning winder in which the fine spinning machine and the winder are connected in a one-to-one manner, signal transmission and reception between the two and supply of a full bobbin from the fine spinning machine to the winder, reception of an empty bobbin from the winder, etc. Control is relatively easy. However, when a plurality of spinning machines and one or a plurality of winders are connected by a bobbin transport path, it is necessary to exchange signals between the plurality of spinning machines and the winders, and control becomes complicated. Further, since the signal lines between different machine bases are connected after both models are installed, a wiring mistake may occur. Further, when a trouble occurs due to a wiring mistake, there is also a problem that it is difficult to find the cause of the trouble because it is a problem across different machine bases.

In order to solve the above-mentioned problems, the applicant of the present application, when the full bobbin and the empty bobbin are directly supplied and conveyed between a plurality of spinning machines and one or a plurality of winders, the spinning machine and the winders are directly connected to each other. A bobbin transfer system for a spinning machine that does not require signal transmission / reception in the above-described system and that allows easy control of the entire transfer system was first proposed (Japanese Patent Application No. 2-195810).
issue). For example, as shown in FIG. 8, this system includes a peg tray 6 between a machine group of a spinning machine 61 and a winder 62.
The transfer line 64 in which the conveyors 64 and 65 for carrying the empty bobbin and the full bobbin using the third bobbin 3 and the peg tray 63 having the full bobbin supplied to the winder mounted thereon travel.
6 is provided, and a feeding device 67 that engages with the peg tray 63 and can temporarily prevent the movement of the peg tray 63 is provided on the downstream side of the one conveyor 65. Then, the peg tray 63 on which the full bobbin fried by the spinning machine 61 is mounted is carried out from the transporting device mounted on the spinning machine table to the transporting conveyor 64 via the connecting device 68. The peg tray 63 is temporarily stored in one of the conveyors 65 as a reserve line, and then the migration line 6
Sequentially sent to 6. Further, the peg tray 63 with a full bobbin that circulates on the circulation line 66 is the winder connecting device 6.
It is sequentially taken into the winder 62 via 9. The feeding of the peg tray 63 with the full bobbin to the circulation line 66 is not performed based on the full bobbin request signal from the winder 62, but is appropriately performed according to the processing capacity of the winder 62.

Further, a reserve line full detection sensor 70 is provided near the upstream end of the transfer conveyor 65, and a portion of the reserve line 67 from the feeding device 67 to a position corresponding to the full detection sensor 70 is provided on the transfer conveyor 65. When the bag trays 63 are continuous, the unloading of the peg trays 63 from the spinning machine 61 is stopped. The maximum range of the storage area of the peg tray 63 with a full bobbin is fixed to the range shown by the arrow A in FIG.
Is located downstream of the end of the maximum range of the storage area. The reason for this is that it is necessary to secure an area for accommodating the peg tray 63 in the middle of transportation when carrying out from the spinning machine that is farthest from the storage area.

[0006]

In the conventional system described above, the full detection sensor for outputting the peg tray carry-out stop signal from the spinning machine is arranged in the storage area based on the spinning machine farthest from the storage area. Since it is arranged on the downstream side of the end of the maximum range, there is a case where the peg tray cannot be carried out from the spinning machine, although the storage area has a margin. In addition, there is a problem that the conveyor for conveying the reserve line becomes long.

The present invention has been made in view of the above problems, and an object thereof is to directly supply and convey full bobbins and empty bobbins between a plurality of spinning machines and one or a plurality of winders. The bobbin transfer system does not require the exchange of signals between the spinning machine and the winder, which simplifies the control of the entire transfer system and allows the spinning machine to control the balls without lengthening the reserve line that temporarily stores the peg tray. It is an object of the present invention to provide a full bobbin carrying method in a spinning machine, which can efficiently carry out a peg tray equipped with a fried full bobbin to a full bobbin carrying path.

[0008]

In order to achieve the above object, the present invention uses a peg tray having a peg projectingly provided on the upper surface between a plurality of spinning machines and one or a plurality of winders. In a bobbin transport system for transporting empty bobbins and full bobbins, a full bobbin transport path of a bobbin transport line consisting of a full bobbin transport path and an empty bobbin transport path provided between a spinning machine group and a winder Locking means that engages with the bag tray to prevent movement of the peg tray is provided, and the maximum number of peg trays that can be stored in the full bobbin transport path upstream of the locking means is set for each spinning machine base. ,
The peg tray with the full bobbin carried out from the spinning machine base is temporarily stored in the full bobbin transport path upstream of the locking means, and the peg tray is appropriately sent downstream according to the processing capacity of the winder. , Counting the number of peg trays carried out to the full bobbin carrying path from the carrying devices provided on the left and right sides of each spinning machine base, and the number of peg trays sent to the downstream side from the locking means, From the value, the number of peg trays on the upstream side of the locking means is obtained, and when carrying out the peg tray with the full bobbin mounted from the spinning machine stand, the peg trays on the upstream side of the locking means are Number and the maximum number of peg trays that can be stored on the machine base are compared, and the peg tray is carried out when the maximum number of peg trays that can be stored is larger. .

[0009]

In the present invention, the maximum number of peg trays that can be stored in the full bobbin transport path upstream of the locking means is set for each spinning machine base. The peg tray loaded with the full bobbin discharged from the spinning machine base is temporarily stored in the full bobbin transport path upstream of the locking means by the action of the locking means, and is appropriately downstream depending on the processing capacity of the winder. Sent to. The number of peg trays carried out to the full bobbin transfer path from the transfer devices provided on the left and right sides of each spinning machine base,
The number of peg trays sent to the downstream side from the locking means is counted, and the number of peg trays upstream from the locking means is obtained from the value. When carrying out the peg tray with the full bobbin mounted from the spinning machine base, the maximum number of peg trays that can be stored on the spinning machine base and the peg tray upstream of the locking means are set. And the maximum number of peg trays that can be stored is larger, the peg tray is unloaded.

When the spinning machine 1 is fully stopped and the bobbin on the peg tray 12 and the full bobbin on the spindle prepared in advance on the transfer devices 14a and 14b are replaced by the pipe changer, the pipe changing operation is completed. The full bobbin can be carried out. Then, in a state where there is room for carrying out the peg tray 12 with a full bobbin on the full bobbin transport paths 4a, 5a, first, the peg tray 12 with a full bobbin is unloaded from the other transport device 14b of the spinning frame 1. Done. After the connection conveyor 15 is set to guide the peg tray 12 with the full bobbin transferred from the other transfer device 14b to the unloading conveyor 16, the connection conveyor 15 and the unloading conveyor 16 are driven, and the other The transport device 14b is driven in the normal direction. As a result, the other transport device 1
The peg tray 12 with a full bobbin on 4b is transferred to the out-end end of the spinning frame 1, and the full bobbin transfer path 4 is passed through the connecting conveyor 15 and the unloading conveyor 16.
It is successively carried out on top of a. The peg tray 12 with a full bobbin delivered from the spinning machine 1 is temporarily stored in the full bobbin reserve area on the upstream side of the feeding device 21. Feeder 21
Are sequentially driven according to the processing capacity of the winder 2, and the peg tray 12 is fed one by one every time the engaging plate 24 engaging with the peg 12a is driven to rotate ⅕. Since the moving speed of the belt 11 is higher than the rotating speed of the engaging plate 24, the peg trays 12 that are in contact with each other on the upstream side of the feeding device 21 are transferred to the migratory line 6 at a predetermined interval.

The maximum number of peg trays Nmi that can be stored on the full bobbin transfer paths 5a, 4a upstream of the feeder 21 is Nmi.
Is different for each spinning machine 1 in accordance with the length of the full bobbin transport paths 5a, 4a from the feeding device 21 to the exit of the carry-out conveyor 16 provided for each spinning machine 1. That is, the full bobbin transfer path 4 a of the first transfer conveyor 4 arranged in a state orthogonal to each spinning machine 1 is also used for the storage area of the peg tray 12. The maximum number Nmi of peg trays that can be stored for each spinning machine 1 is stored in the main controller 26 in advance. Each time one peg tray 12 is unloaded from the unloading conveyor 16, a pulse signal is output from the detection sensor S1 and sent to the main controller 26 via the spinning-side transfer control device 25. Further, every time one peg tray 12 is sent out from the feeding device 21, a pulse signal is output from the detection sensor S2 and sent to the main controller 26 via the winder side transfer control device 27. The main controller 26 determines the number of peg trays 12 delivered to the full bobbin transport paths 5a, 4a and the number of peg trays 12 delivered from the feeder 21 based on the pulse signals output from both detection sensors S1, S2. The number Np of the peg trays 12 on the upstream side of the feeding device 21 is calculated from the counted values. That is, the number Np of the peg trays 12 on the upstream side of the feeding device 21 is incremented by 1 when the detection sensor S1 outputs 1 pulse, and is subtracted by 1 when the detection sensor S2 outputs 1 pulse.

Then, the main controller 26 sets the maximum number Nmi of storable peg trays set in the spinning machine 1 to carry out the peg tray 12 and the number Np of peg trays upstream of the feeding device 21. When the maximum number Nmi is larger than the number Np, the operation instruction signal of the carry-out conveyor 16 is output to the spinning-side transport control device 25, and when the maximum number Nmi is less than the number Np, the spinning-side transport control is performed. A stop instruction signal for the carry-out conveyor 16 is output to the device 25. The carry-out conveyor 16 according to this instruction signal
Is driven and stopped, and the peg tray 12 is unloaded. That is, while the peg tray 12 can be stored between the feeding device 21 and the unloading conveyor 16 of the spinning machine 1 that requires unloading of the peg tray 12, the unloading conveyor 16 is reliably driven to unload the peg tray 12.
