A notch 40a is formed at the tip of the dropping chute 39 so that the empty bobbin E that has been dropped can be moved from inside the dropping chute 39 to the outside, and a notch 40a is formed at the tip of the dropping chute 39 to ensure that the empty bobbin E that has been dropped is so that it is inserted onto the peg 4c,
A guide plate 40 is attached to this notch 40a so as to be openable and closable, and is urged by an extremely weak spring force in a direction opposite to the traveling direction of the peg conveyor 4 to form a guide passage 41. The operation will be explained. Full bobbin gripping device! 128 is on standby with its movable claw 28C engaging with the cam 30 at the gripping position so that the head M1 of a full bobbin M can be inserted. On the other hand, the full bobbin M doffed onto the peg conveyor 4 is conveyed one pitch at a time by the peg conveyor 4, which is activated by an unloading command from the autowinder 16 or the like, and when the full bobbin M reaches the gripping position, The head M1 is inserted into the fully loaded bin gripping device 28, and
The peg conveyor 4 is stopped by the signal that the full bobbin confirmation photoelectric switch 27b is blocked, and the clutch 25 is energized and the rotation of the drive motor 26 is stopped by the chain sprocket 24. transmitted to.

As a result, the cheno 22 is rotated, and the full bobbin gripping device 2
The movable claw 28Q of No. 8 disengages from the cam 30 at the gripping position and grips the head M1 of the full bobbin M, and the gripped whirlpool bobbin M
Pull upwards and fry. This rotation of the cheno 22 brings the next full bobbin gripping device Ft28 to the gripping position, and when the photoelectric switch 27a is blocked by its light shielding portion 28cl, the clutch 25 is disengaged and stopped by the signal. At the same time, the peg conveyor 4 moves one pitch again in response to a signal from the photoelectric switch 27a. In this way, the full bobbins M are picked up one after another in a short period by the plurality of full bobbin gripping devices 28, or the vortex bobbin gripping device ff that grips the full bobbin M
128 is in the released position+mK''+ (in this embodiment, the ceno 22 stops at exactly this position).The full bobbin gripping device W2

The movable claw 28c opens the release blade 11"+j 58-74408
The full bobbin M is moved in the direction (5) against the barbs 28b, and the gripped head M1 of the full bobbin M is released, and the full bobbin M falls. The lower end M2 of the slope 29 & groove of the fallen bobbin 29 directly below is scooped up in the direction opposite to the ejection direction and hits the protrusion 29b, and the head M1 of the full bobbin is tilted in the ejection direction.

At the same time as it falls down, the full bobbin M rolls along the slope of the full bobbin chute 20 and is carried *a onto the full bobbin conveyor 13 through the discharge hole 20a at the tip of the full bobbin chute 20. The full bobbin M placed on the full bobbin transport conveyor 13 passes over the creel 6A of the spinning machine 1b and is transported to the full bobbin supply device 18 of the autowinder 16 in the next step. In this way, when the unloading of the full bobbin M of one spinning frame (for example, spinning frame 1a) is completed, the full bobbin M of the other spinning frame (1b) is then unloaded by the unloading command of the auto winder 16, etc. They are fried one after another in the same short cycle. By the way, if the fully loaded bin M doffed onto the bed conveyor 4 is conveyed in advance to just before the gripping position and is kept on standby at that position, the droplet can be immediately removed when there is a command to unload the O & 17 twiner 16, etc. This is preferable because the bobbin M can be lifted out.

On the other hand, the empty bobbin E is transferred from the autowinder 16 via the empty bobbin discharge conveyor 17 to the empty bobbin transport conveyor 12.
The part is placed on the top and conveyed to the creel 6A-,
The notch 12f is formed by the guide plate 12c or the movable guide plate 12θ.

When it is confirmed by the limit switch LSI that c is positioned directly below the empty bobbin supply device 62, the series Y is detected.

The first under 36b reciprocates, and the guide path 6 of the stock device 34
Drop the empty bobbin chutes in 5 one by one and insert them into the hook 4c. In this way, when the empty bobbins E are inserted into all the pegs 40 after the full bobbins M have been unloaded, the bet conveyor 4 returns to the position facing the spindle 5 of the spinning machine and waits until the next doffing.

In the above embodiment, the explanation has been given of a system that is applied to a pair of spinning machines and discharges full bobbins onto a full bobbin conveyor that passes through the upper part of the creel shop 18. It is also possible to remove the full bobbin at the end of one spinning machine and discharge it to the -C primary process. Furthermore, although the peg conveyor has been described as one that circulates in the horizontal direction, it may also be a peg conveyor that rotates in a vertical plane along the spindle rows separately on the left and right sides of spinning (2). Furthermore, in the above embodiment, the full bobbin gripping device reaches the gripping position and the release position simultaneously and engages with the holding means and stops. However, the full bobbin holding device may engage with the holding means while moving. The release position may be determined so as to. Incidentally, the discharge direction is not limited to the second embodiment, and can be set in any direction except for the side where the chain is stretched.

As described above, in the present invention, the chain wheel is wound intermittently around the upper and lower chain brockets provided on the machine frame,
19. A full bobbin gripping device with a movable claw capable of inserting the head of a full bobbin from the horizontal direction and gripping and releasing the head in a state located at the upper transition part of the cheno is discarded. In addition, when a full bobbin gripped by the full bobbin gripping device is released while it is located at the upper transition part of the cheno, the lower end of the full bobbin is stopped and the head of the full bobbin is fixed. A receiving tray that can be tilted in the ejecting direction from the upper part first is attached to each machine frame, and a retaining means is attached to each machine frame to allow the movable claw of the full bobbin gripping device to act at two arbitrary locations above and below the upper transition part of the cheno. By connecting it to the bedding conveyor installed at the bottom of the spinning machine, full bobbins doffed on the bedding conveyor can be unloaded one after another in a short period of time, making it possible to cope with the high speed of the autowinder. In addition, in the full bobbin release position, simply releasing the grip on the full bobbin ensures that the bobbin is tilted from its head and prevents the winding thread of the full bobbin from unraveling. ....
