DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an empty bobbin feeding device for a roving frame.

Conventional technology In recent years, as part of rationalization of roving machines,
In order to improve operating efficiency, there is a remarkable trend toward higher speeds and larger packages, and with this, streamlining the work of replacing tubes after full tubes and discharging full bobbins has become an urgent issue. In other words, manually handling full bobbins in large packages is not only extremely labor-intensive for workers, but also significantly increases the time required for the work, reducing the operating efficiency of the roving frame. . For this reason, automation of these operations has been desired, and various devices have been devised to achieve automatic discharge of full bobbins and automatic supply of empty bobbins.

Conventional automatic empty bobbin supply devices require a storage section for storing a large number of empty bobbins in addition to an empty bobbin supply section for supplying empty bobbins one by one to the bobbin holder on the conveyor means, making it difficult to use a large package. The drawback is that a large amount of space is required to store a large number of empty bobbins, which have become longer in size.

They are not driven at the same time, but are driven when the number of empty bobbins 25 in the empty bobbin supply box 55 becomes one.

Next, the operation of the empty bobbin supply device constructed as described above will be explained.

Now, when the roving is fully wound around the bobbin 11 by the operation of the roving frame and a full bobbin 19 is formed, the winding movement is stopped and the lower frame 5 in the winding up position shown in FIG. The spindles 3 of each flyer 2 are lowered as one from the winding lifting range, and the spindles 3 of each flyer 2 are pulled out from the upper end of each bobbin 11 all at once, as shown in FIG. And conveyor rail 7
When the lower end surface of the guide rod 76 fixed to the conveyor rail 7 comes into contact with the stopper 9, the lowering movement of the conveyor rail 7 is restricted, and only the bobbin rail 6 is separated from the conveyor rail 7 and further lowered. Due to the lowering operation, the bobbin drive shaft 10 that had been fitted into the bobbin 11 was also lowered all at once, and the bobbin 11 was separated from the fitting support cylinder portion 10a of the bobbin drive shaft 10 and was fitted into the bobbin support cylinder 17a. It is placed on the bobbin holder 17 in this state.

After all the full bobbins 19 are placed on the bobbin holder 17 as described above, the cart 20 with empty bobbins 25 inserted into all the pegs 26 is carried into one end of the machine base. The truck 20 moves along the rail 21, and as shown in FIG. The bobbin 25 stops at a position corresponding to the empty bobbin transfer device 55.

Ru. When the other guide rail 67b is rotated outward, the other end of the lever 74, which is connected at one end to a support bracket 71 fixed inside the guide rail 67b via a support shaft 71a, is rotated via a connecting pin 75. The control bracket 72 moves downward along the elongated hole 72a, and is connected to the support bracket 70, which has one end connected to the connecting pin 75 and the other end fixed to the inner surface of one of the guide rails 67a, via the support shaft 70a. Due to the action of the lever 73 connected to each other, one guide rail 67a is also rotated outward about the hinge 68 against the spring force of the torsion spring 69.

When the guide rails 67a and 67b are further lowered from the position shown by the chain line in FIG. , both guide rails 67a, 67b are rotated back inward by the spring force of the torsion spring 69, and the tips of both guide rails 67a, 67b are positioned below the flange portion 25b, as shown on the lower side of FIG. In this state, the operation of the cylinder 58 is stopped.

After a limit switch (not shown) confirms that the piston rod 60 has protruded to a predetermined position, the cylinder 58 is activated, the piston rod 60 is retracted, and the empty bobbin hanging device 61 begins to rise. When the empty bobbin hanging device 61 is slightly raised, both guide rails 67 are moved as shown by chain lines in FIG.

5a is disengaged from the engaging piece 41, and the empty bobbin 25 is moved so that the bottom of the large diameter portion 25a is attached to the bottom wall 4 of the empty bobbin supply box 37, as shown in FIGS. 19 and 10.
The large diameter portion 25a is supported on the bottom wall 40 with the peripheral surface of the large diameter portion 25a in contact with the leaf spring 44 and the flange portion 25a in contact with the guide plate 53. The second to fourth empty bobbins 25 slide on the guide surface 48a of the guide member 48 in the same manner as the first empty bobbin 25, and slide on the guide surface 48a as shown in FIG. When the bobbin 25 comes into contact with the empty bobbin 25 located in front, the guide surface 4
It is held suspended above 8a.

Then, the bobbin holder 17 from which the full bobbin 19 has been removed from the bobbin support cylinder 17a in the circumferential portion of the chain conveyor 16 due to the action of the full bobbin discharging mechanism (not shown) is removed from the circumferential portion by the movement of the chain conveyor 16, as shown in FIG. The bobbin supporting cylinder 1 of the bobbin holder 17 is then moved to the empty bobbin supply box 37 and inserted into the notch 40b of the bottom wall 40.
7a, a portion of the inner circumferential surface of the lower end of the empty bobbin 25 held at the forefront in the empty bobbin supply box 37 is hooked onto a portion of the outer circumferential surface of the upper end of the bobbin support cylinder 17a. As the bobbin holder 17 moves, the empty bobbin 25 is moved forward against the leaf spring 44 and gradually moves to the bobbin support cylinder 17a.
The bobbin holder 17 is fitted into the bobbin holder 17, released from the pressure of the leaf spring 44, and placed on the bobbin holder 17. and,
As shown in FIG. 21, the second empty bobbin 25 suspended above the guide surface 48a of the guide member 48 is attached to the bottom wall 40 in the same way as the first empty bobbin 25.
supported above. Thereafter, the empty bobbins 25 in the empty bobbin supply box 37 are sequentially supplied and placed on the bobbin holder 17 in the same manner.

When there is only one empty bobbin 25 in the empty bobbin supply box 37, it is detected by a detection means (not shown), and the motor 87 is driven by the detection signal, and the toothed belt 84 moves half a turn to suspend the empty bobbin. Empty bobbins 2 in the second row suspended from the device 61
5 are all transferred to the empty bobbin supply box 37. Next, the intermittent feed device 28 is activated, and the cart 20 is moved in the same manner as described above to feed the empty bobbins 2 in the third row.
5 comes to a position corresponding to the empty bobbin transfer device 55. When the phototube PH1 detects the empty bobbin 25, the empty bobbin 25 is suspended from the empty bobbin hanging device 61 in the same manner as described above.

Thereafter, the full bobbin 19 placed on the bobbin holder 17 in the same manner as described above is discharged by the bobbin discharge mechanism, and the empty bobbin 25 is sequentially supplied from the empty bobbin supply box 37 onto the bobbin holder 17 from which the full bobbin 19 has been removed. It will be placed. Then, the pipe replacement work is completed while the chain conveyor 16 moves one round.

Note that the present invention is not limited to the above-mentioned embodiments. For example, the guide rails 67a and 67b of the empty bobbin hanging device 61 may be configured to be opened and closed by a cylinder instead of using a cam means, or The bobbins 25 may be taken out one by one from the cart. Also, the bobbin rail 6 of the spinning machine
A separate conveyor is installed along the machine base, and during pipe change work, the empty bobbin 25 placed on the conveyor is transferred onto the bobbin rail 6 by a pipe change device. The present invention may also be applied.

Effects As detailed above, this invention carries a cart loaded with empty bobbins vertically to the end of the spinning machine table, takes out the empty bobbins upward from the cart while holding them in an upright position, and then moves them laterally. Then, the empty bobbins are supplied to an empty bobbin supply box for supplying the empty bobbins one by one to the bobbin holder on the conveyor means.In this case, the empty bobbins are loaded in rows on the cart. Since a plurality of bobbins corresponding to one row are fed into the empty bobbin supply box, empty bobbins can be efficiently supplied with intermittent movement of the cart. Moreover, an excellent effect is achieved in that there is no need to provide a storage section on the spinning machine stand for storing a large number of empty bobbins that have become long due to the large package.
