Abstract

PURPOSE:To set a full bobbin, in the case of full bobbin stop, to a posture effective for the prevention of end breakage at the restart of the operation, by transferring the traveller positioned at the auto-doffer side to the rear side of the spindle row by the rotation of the full bobbin. CONSTITUTION:When the presence of the guide yean 2 at the front side(side of autodoffer AD) of the spindle row 1 is detected by the sensor S, the solenoid 6 is magnetized and the face plate 3'' is thrust into the wound yarn layer L to a depth of about 2mm by the swinging action of the supporting member 8 for the pressing plate caused by the pulling action of the chain 7. Taking advantage of the contact pressure in combination with the movement of the autodoffer AD, the full bobbin B is rotated actively at a definite angle to the direction of the rotation of the spindle 1. The traveller is transferred to the rear side of the spindle row 1 by the rotation of the full bobbin B, and the bobbin B is forced to take the doffing posture suitable for the prevention of end breakage.

Description

[Detailed Description of the Invention] The present invention relates to a neck-related device for regulating the travel position of a spinning machine. This invention relates to a traveler position regulating device for a spinning machine that moves the traveler of the spinning machine to the rear side of the spindle row for the purpose of preventing thread breakage when restarting operation when hoisting a pipe bobbin.

(B) Prior art In order to requisition full bobbins from spindles of spinning machines such as spun plates and twisted yarns, and to supply empty bobbins to the spindles in exchange, a group-spindle lifting method or a single-spindle lifting method is used. Auto dotsfa is used. After the doffing is completed by such automatic doffing, the operation of the spinning machine is started according to the usual method, but if there are not enough yarn breakers when the operation is restarted, the spinning machine will start spinning. This is an essential requirement for improving Oki 1 Hajime.

Is there a shadow on the number of light breaks that occur when the VCh is turned on when operating a spinning machine?
One of the factors that affect h is the condition of the winding of the tail thread and the shape of the thread from the snell tsuya to the traveler.lz It can be reduced, but especially when using an auto doffer, The relative position between the doffing doff'r1^ of the doffing machine and the traveler of the spinning machine has a large influence on the number of threads that occur.

In the sentence, ij[L <Explanation 1. Then, with the spindle of the spinning machine as the center, the angle is about 5 degrees to the left and right to the main body of the auto dossier.
It is known that when doffing is performed using the auto doffer with the traveler positioned in the range σ-11, thread breakage occurs frequently during operation (IJl river).

In order to prevent yarn breakage of the spinning machine when the spinning machine is opened during such operation, the conventional auto-dossfer is made to have a relative relationship between the road thread and the auto-ton 7a, and the visiting thread is placed after the spindle row. A plate-shaped or par-shaped guide member is provided on the side, that is, on the roller beam side of the spinning machine. Prior to the exchange of a full bobbin and an empty bobbin by the automatic solenoid 7a, the thread thread is moved to the rear side of the spindle row by driving the guide section Kirigata, so if such a guide member is not provided. Compared to this, the number of thread breaks during restart U1 is considerably reduced.

However, the above-mentioned guide/guide member merely displaces only the guide thread relative to the autoton 7a, and therefore does not perform any position regulating function for the full bobbin or the traveler. I can't. In conventional spinning machines, when the auto doffer is operated, the doffing of the auto doffer interferes with the crosspiece structure, and when the spinning and iso operation manual is opened, there are many problems with thread breakage. It was done.

(b) Purpose of the Invention The main object of the present invention is to convert the doffing method to doffing using the automatic doffing method.
An object of the present invention is to provide a traveler position regulating device for a spinning machine that allows a traveler of a spinning machine to be positioned at 9% VC9 in an area behind a spindle row suitable for preventing thread roll.

(e) Effects of the invention As explained above, the plane regulating device for the Y rappeller position of a spinning machine related to wood starting is designed to imitate a traveler that is positioned on the auto-starting side when the spinning machine is fully stopped. The spindle row is displaced to the rear side through the rotation of the bobbin, and the full bobbin is given a doffing posture that is effective for preventing thread breakage when restarting operation. By using the Kihatsu EJ4 device for company use, yarn breakage during re-operation after doffing a full bobbin will be significantly reduced, so we expect it to have a significant effect on improving the productivity of the spinning and carding process as well as the quality of spun yarn. can do.
