The reed switch RS7 is turned off by the movement of the piston 17 located at the position corresponding to the reed switch RS7 with the operation of the air cylinder B2. Reed switch RS7 is O
0.1 seconds after the FF state, the air cylinder A2 is operated, the piston rod 15 in the retracted state is projected, and the transfer rails 14a and 14b are moved forward a distance slightly larger than the spindle pitch. When the transfer rails 14a, 14b move forward, the peg tray 2 on the transfer rails 14a, 14b attaches the locking piece 20 to the spring 2.
It is rotated downward against the force of 2 and passes above it, and is transferred by the amount of forward movement of the transfer rails 14a and 14b. At this time, the peg tray feed claws 35 provided at the rear ends of the transfer rails 14a and 14b.
Alternatively, the engaging member 38 contacts the recess 2b of the peg tray 2 or the outer peripheral surface of the peg tray 2, so that the peg tray 2 is reliably moved integrally with the transfer rails 14a, 14b. Then, after the reed switches RS8, RS4 attached to the air cylinders A2, B2 are turned on, that is, after the depression of the piston rod 15 of the air cylinder B2 and the projection of the piston rod 15 of the air cylinder A2 are completed, When the air cylinder B1 is operated and the piston rod 15 is retracted, the transfer rails 14a and 14b are moved forward. 0.1 seconds after the reed switch RS6 is turned off by the operation of the air cylinder B1, the air cylinder A1 is operated and the transfer rails 14a and 14b are also moved forward so that the peg tray 2 is moved by about one spindle pitch. As a result, the leading peg tray 2 is arranged at a position where it can be engaged with the feed lever 26, as shown in FIG. On the other hand, simultaneously with the operation of the air cylinder B1, the air cylinder A2 is operated and the piston rod 15 is retracted, and simultaneously with the operation of the air cylinder A1, the air cylinder B2 is operated and the piston rod 15 is projected, so that each full / empty bobbin transfer is performed. The transfer rails 14a, 14b of the devices T3, T4 return to their original positions. As a result, the transfer rails 14a, 14b of the full / empty bobbin transfer device T3

When the 14a and 14b are returned, they are rotated downward to separate from the recess 2b and pass below the peg tray 2.

Similarly, the transfer rails 14a and 14b are reciprocally moved and the feed lever 26 is reciprocally rotated.
The peg trays 2 on the guide rails 14a, 14b, the guide rails 23, and the direction changing rails 13 are transferred in the direction of the arrow in FIG. As a result, the peg tray 2 with the full bobbin inserted therein is sent to the full bobbin transfer path 7 of the winder 1 via the full bobbin unloading conveyor 5, and the peg tray 2 with the empty bobbin inserted is moved into the empty bobbin transfer path of the winder 1. Transfer rail from 6 to the empty bobbin loading conveyor 4
The peg tray with full bobbins on the transfer rails 14a, 14b is exchanged for the peg tray with empty bobbins.

In this device, the full / empty bobbin transfer devices T1, T2, T3, T4 arranged on the left and right sides of the two spinning machines 3 are connected by a guide rail 23 and a direction changing rail 13, respectively. Since the peg tray 2 in which the empty bobbin E is inserted is also placed on the direction changing rail 13 so as to be in contact with each other, a new drive source is used to connect both transfer devices T1, T2, T3, T4. It is not necessary and the structure is extremely simple. If all the air cylinders have the same starting characteristics, the peg tray 2 can be transferred even if the air cylinders B2, A2, B1, and A1 are simultaneously operated, but generally, the starting characteristics of the air cylinders vary. is there. Therefore, even if an actuation signal is received at the same time, the activation of the air cylinder varies, and the upstream air cylinder operates before the air cylinder arranged on the downstream side operates. However, there is a risk that the transfer of the peg tray will be hindered, but in the present invention, the air cylinder arranged on the downstream side is operated and the air cylinder arranged on the upstream side is operated after a certain time has elapsed. Therefore, the peg tray 2 can be transferred smoothly.

It should be noted that the present invention is not limited to the above embodiment, and for example, the completion of the immersion of the piston rod 15 of the air cylinders B1 and B2 arranged on the downstream side, that is, the reed switch RS.
5, After RS8 is turned on, the air cylinders A1 and A2 arranged on the upstream side are configured to operate, or the widths of the out end OE and the gear end GE are made the same as shown in FIG. Even if the full / empty bobbin transfer devices T1, T2, T3, T4 and the guide rail 23 are configured so as to form one straight line, or the spinning machine 3 is arranged so that the out end OE and the gear end GE face each other. Good. Further, the number of spinning machines 3 may be increased from two, or a hydraulic cylinder may be used instead of the air cylinder. Furthermore, in addition to the spinning winder directly connected to the winder,
It may be simply used to carry out a full bobbin from a spinning machine or the like and to carry an empty bobbin into a spinning machine or the like.

EFFECTS OF THE INVENTION As described above in detail, according to the present invention, even if the number of transfer devices for connecting the winder and the spinning machine is small, the peg tray can be transferred smoothly and the drive source thereof is also reduced. Therefore, the control system is simple and the equipment cost is low. In addition, it is possible to rationalize the transfer of empty and empty bobbins by a very simple modification in which the layout of the existing spinning frame is changed and the guide rail of the peg tray is added. In addition, even in the case of a spinning machine that has a large draft load such as a spinning machine with a super high draft draft section, the machine frame cannot be lengthened. It is possible to carry out and carry out in the same manner as in the case of using a large number of frustums, and it is possible to improve the efficiency of those operations.
