Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a yarn package changing system in a warping machine.

(Prior Art) FIG. 6 shows a conventionally used warping machine. A creel b supported by an endless chain a is disposed in a creel disposing portion of the warping machine, and a guide member c is disposed on the outside of the creel b. The yarn of the yarn package d hooked to the outer surface P of the creel b is guided to the warping head e via the guide member c and wound thereon. A fully wound yarn package d is hooked onto the inner surface Q of the creel b and is waiting to be used for the next winding operation.

The yarn of the yarn package d on the outer surface side P is warped at the warping head e.
When the warping operation is completed, the endless chain a makes half a turn and moves the fully wound yarn package d to the outer side P to prepare for the next warping operation, and also removes the used yarn package d. Move it to the inner side Q. During the next warping operation, the used yarn package d is manually removed, and in its place a fully wound yarn package d is hung on the inner surface Q of the creel b and is on standby.

In the above conventional example, the thread package d is replaced on the inner surface Q of the creel b during the warping operation using the thread package d hooked on the outer surface P of the creel b. There is a warping machine that is equipped with a number of rotating creel frames on the outer surface of which yarn packages d can be hooked.

(Problem to be Solved by the Invention) According to the above-mentioned conventional example, hundreds to thousands of used yarn package cages are removed from the creel, placed on a transport vehicle, and transported to the winder. The entire process of loading the yarn package cages onto a carrier, transporting them to the creel placement area, and hooking them onto the creel must be done manually. For this reason, there is a problem in that the operator is forced to perform long and complicated work, which increases the work cost. Particularly in recent years, when yarn package cages are becoming larger, heavy labor is imposed on workers, and it has become an important issue to save labor.

It is an object of the present invention to solve the above-mentioned problems and to quickly replace the yarn package.

(Means for Solving the Problems) In order to achieve the above object, the present invention divides the creel placement section into three lines: a yarn guide line, a standby line, and a main line located between these lines, and arranges a large number of yarn packages. A movable cassette creel, on which the yarn is hung, is disposed on each of the main line and the standby line so as to be held by a guide rail, and a track changing device is provided between the guide rails of both lines, while the The present invention is characterized in that a guide member is disposed on the guideline to guide the yarn of the yarn package on the main line to the warping head.

(Function) According to the present invention, when the warping work is completed and the yarn package is to be replaced when moving on to the next warping work, the cassette creel on the standby line is transferred to the main line by the guide rail and the track changing device. This is possible and can be done quickly by moving.

Furthermore, since the cassette creel has both the function of latching a large number of thread package cages and the function of a transport vehicle (for this reason, it is constructed separately from the thread guide member), the thread package cages can be removed from and hooked to the cassette creel at the same time. The transfer work can be halved compared to conventional methods.

Furthermore, the cassette creel can be moved to a location where it is most advantageous to replace the yarn package. For example, it is possible to move the cassette creel to an automatic package changer so that the thread packages can be changed automatically.
