Description

[Detailed Description of the Invention] Industrial Field of Application This invention provides a method for using small bobbins in two rows, front and rear, when the bobbins suspended from the bobbin hangers of two rows of creels in a spinning machine become small bobbins. The present invention relates to a method for replacing a full bobbin on a spare rail provided on a creel, and a Shino exchange machine suitable for carrying out the method.

When the Shinomaki bobbin of the creel of a prior art spinning machine becomes a small bobbin or an empty bobbin, it must be replaced with a full Shinomaki bobbin. The Shinomaki Manpobin weighed nearly three centimeters, and it was hard work for workers to suspend it from a creel at a high place. Therefore, in order to automate such Shino replacement work, ■ When the Shinomaki bobbin in the front row becomes a small bobbin, it is possible to replace multiple (for example, 6) front row small bobbins and multiple full bobbins on the spare rail. Shino exchange is carried out together with Shino Tsugu, and before the next Shino exchange, the replaced full bobbin in the front row and the medium bobbin in the rear row that is currently being spun are exchanged by a Shino shunter (Japanese Patent Laid-Open No. 1983-1999). 53425), ■In order to replace the pair of small bobbins on the front and rear of the creel (hereinafter referred to as the pair of small bobbins on the front and rear) and the two full bobbins on the spare rail every other row along the longitudinal direction of the machine, An empty Shino-maki transfer device and a full Shino-maki transfer device, each equipped with a pair of pegs, are installed in parallel in the Shino exchanger body, and the pitch in the longitudinal direction between the four pegs matches the creel's pohin bitch. In addition, the empty and Mitsushi winding transfer device requires a work space corresponding to four creel bobbins in the longitudinal direction of the machine (Japanese Patent Application Laid-Open No. 119728/1983), or this is combined with Shino Tsugi. (Japanese Unexamined Patent Publication No. 2-127368).

Invention or problem to be solved According to the above-mentioned conventional technique (2), two or more pieces of wires are exchanged at the same time, which takes 1E, so the time required to change the wires per spinning machine is much longer than in (2). However, there is a practical problem in that it is limited to spinning machines equipped with a Shino shunter as mentioned above. Also,
According to (2), although there is an advantage that the shinobi shunter required in the above-mentioned (2) is not required, since the shinobi shunter is replaced one after another, the time for changing the shinobi for the spinning frame frame is longer than that in the above-mentioned (2), which is not preferred in practice. In addition, in order to exchange the small bobbins in the front and rear rows, the empty and full bobbin transfer device requires work space corresponding to the four creel bobbins in the longitudinal direction of the machine, so in order to shorten the bobbin exchange time. Even if a plurality of sets of the empty and full bobbin transfer devices are mounted on the main body of the Shino exchanger and a plurality of pairs of front and rear bobbins are exchanged at the same time, the working space overlaps and the plural pairs of full and small bobbins are replaced. It is not possible to maintain the positional relationship with each of the corresponding transfer devices, and in the end, method (2) can only handle two weights in the front and back at the same time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for simultaneously exchanging a plurality of small bobbins of a creel of a spinning frame in units of front and rear pairs, and a suitable exchanger for carrying out the method.

Means for Solving the Problem The Shino replacement method for achieving the above purpose is to replace the spare rail with
Unload the front and rear pairs of small bobbins to be replaced on the creel and the corresponding left and right pairs of full bobbins to the Shino exchange machine, and move one of the unloaded left and right pairs of full bobbins to the front or rear side of the other. Sort the full bobbins into front and rear pairs using the Shino exchange machine, remove the small bobbins of the front and rear pairs to be replaced from the bobbin hanger of the creel, take them out as front and rear pairs next to the corresponding full bobbins of the front and rear pairs, and place the full bobbins of the front and rear pairs. , insert the small bobbin into the bobbin hanger of the front and rear pair of the removed creel, move one of the removed small bobbin of the front and rear pair to the left or right side of the other, rearrange it into a left and right pair, and adjust the left and right pitch to the bobbin pitch of the creel. The left and right pairs of small bobbins are then inserted into the left and right pair of bobbin hangers on the spare rail from which the full bobbins have been removed, and these operations are repeated sequentially from one end of the machine to the other. It is characterized by In addition, as a suitable Shino exchanger for carrying out this method, an even number of peg units each having a pair of front and rear pegs are installed in the main body of the Shino exchanger, and the left and right pitch of the pegs to the adjacent pesog units is set to the bobbin hanger of the creel. They are arranged side by side to match the left and right pitch, and each peg unit un has one peg ′ aligned with the other peg in the front-rear direction, and the other peg in the left-right pitch of the creel bobbin hanger.

・A bobbin transfer device is installed between each set of peg units to transfer the bobbin between the front peg of one peg unit and the rear peg of the other peg unit 1-. Proposed.

According to the method described above, the left and right pairs of full bobbins are made into front and rear pairs, and the front and rear pairs of small bobbins are taken out next to them as front and rear pairs, and then the front and rear pairs of full bobbins are hung from the front and rear bobbin hangers of the creel. By suspending the front and rear pairs of small bobbins as a left and right pair from the spare rail after removing the full bobbin, the working space in the machine longitudinal direction required to replace the front and rear pairs of small bobbins corresponds to that of two bobbins. Therefore, even if a plurality of pairs of front and rear bobbins are replaced at the same time, the adjacent work spaces do not overlap.

Further, according to the device of claim 2, by using the peg moving device of each peg unit to move the other pen with respect to one peg serving as a reference between the original position and the displaced position,
Bobbin arrangement conversion is performed between the front and rear pair and the left and right pair while the bobbin is placed on the peg.

Furthermore, according to the apparatus of claim 3, the bobbin transfer device transfers the bobbin between the front peg of one of the two adjacent units 1 to 1 and the rear peg of the other peg unit. By transferring the bobbin arrangement, the bobbin arrangement is converted between the front and rear pair and the left and right pair.
