Abstract

PURPOSE:To shorten the doffing time by performing the operation of cheese take-out arm simultaneously with motion of cheese transporter while performing the transferring operation of cheese to the peg of transporter simultaneously with motion of doffing machine thereby performing the doffing operation simultaneously and continuously. CONSTITUTION:Upon provision of doffing operation starting signal, yarn holding guide 24 and thread handler guide 23 will function to wind the thread over a waist roller 13. Then a cradle 7 will arrive to the doffing position to project the sliding arms 32, 33 thus to stop a bobbin 55 by means of a grip click 37 at the tip and to take out the cheese 56 by means of third sliding arm 35. While upon entering of movable click of chuck 46 into the bobbin 55, said clock 37 will open to release gripping of bobbin 55. At the sametime, the table 39 will move to mount the cheese 56 onto the peg 16a of cheese transporter 16. Consequently, the chuck 46 will separate from the bobbin and the table 39 will return to the original position. Since the third sliding arm is already entering into take-out work of second cheese at this time, continuously doffing work can be achieved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention provides a method for rolling a ball [and a cheese transport vehicle] along the longitudinal direction of a machine such as a stretch winder, a stretch false twister, a spinning machine, etc. The present invention relates to an automatic doffing machine that simultaneously doffs multiple full cheese rolls in the same row wound up in multiple winding sections arranged in parallel in the longitudinal direction of the machine.

Generally, polyester or polyamide synthetic fiber stretch winding machine, stretch false twisting machine, air bulking machine, or synthetic mm
A spinning machine for spinning , natural GA fiber, etc. has a structure in which a plurality of rows of yarn processing sections and winding sections are arranged in the longitudinal direction of the machine stand. or,
The winding section has multiple winding devices installed in the same row, and
A bobbin is supported parallel to the longitudinal direction of the machine and the yarn is wound as a straight end cheese or taber end cheese.

These cheeses have large diameters and large U shapes for reasons of productivity and rationalization, making doffing difficult for workers.
Also, contact with the yarn layer during doffing can cause uneven weaving, uneven dyeing, etc. in the post-processing process, so it is desired to develop a device that can doff automatically.

Therefore, the processing section and the winding section are installed in separate frames, and when the cheese on the stock ladle is fully wound, the yarn is wound on a roller, etc., and the winding ladle is rotated upward. Therefore, a device has been proposed in which doffing is carried out on a rail installed on the opposite side of the processing section.

A device with such a configuration is disclosed in, for example, Japanese Patent Application Laid-Open No. 57-121564.
It is stated in the No.

However, with the device configured as described above, it is possible to temporarily store a full roll of cheese on the rail by operating the winding ladles installed on the machine all at once and doffing.
Since the winding section is installed on a separate frame, the installation area of the machine becomes large, and full rolls of cheese must be transferred from the rail to a cheese transport vehicle, a conveyor, etc., which is unsatisfactory.

Further, as shown in FIG. 6, a full cheese take-out arm 60 is provided on the movable cart 61, which moves in the vertical and front-back directions and rotates 180 degrees in the horizontal direction.
Eleven machines have been proposed which are configured to be mounted on pegs 63 of a cheese transport vehicle 62 for taking out individual pieces.

However, with this configuration, the doffing operation for all the full cheese rolls is performed using one take-out arm 60, which increases the doffing time, and the gripping of the outer layer of cheese threads causes uneven dyeing in the post-processing process. There is a problem in that uneven weaving occurs. Therefore, in order to shorten the doffing time,
Even if an attempt was made to install the above-mentioned ejection arm in multiple stages, the configuration would be complicated, and the members forming the ejection arm would interfere with each other, making it extremely difficult to put it into practical use. A satisfactory doffing machine has not yet been put into practical use.

The present invention solves the above-mentioned problems and provides an automatic doffing machine that can shorten the doffing time and moreover reliably doff.
