Description

[Detailed Description of the Invention] This invention holds and stands by the ends of a large number of threads when knitting and weaving threads to be subjected to physical property tests, and successively switches and connects a large number of threads to the knitting and weaving for testing. It relates to a feeding device.

Conventionally, it is customary to take a small amount of yarn from a single spool of yarn for testing, knit and weave it, compare dyeability, etc. in knitting, and sort out the matrix, so many spools of yarn are used. If you try to pull out some of the threads placed nearby and use them as a spare, problems such as thread entanglement or excessive loosening are likely to occur due to the effects of air conditioning, etc., and each process requires about 10 threads to be wound. The limit was the deployment of Therefore, it is necessary to frequently replace 20 to 30 kg of deployed yarn in the vicinity, and in addition, it is necessary to subject the final yarn take-out part to the connecting process and remove the remaining yarn after cutting, which requires constant manual labor, which is complicated and requires unskilled labor. It required careful consideration.

This invention deploys 70 to 90 winding threads at a time during the above operation, holds the take-out end of the thread under appropriate tension and waits, and then automatically changes and connects the threads at each time. The object is to obtain a device for feeding yarn.

The present invention will be explained as follows based on an embodiment in which the invention is implemented as a connection standby device for test yarns.

The first illustration is a perspective view showing the structure of the present invention. The suction port 1 is installed horizontally with its opening surface, and communicates with an exhaust mechanism 6 such as a blower at the bottom.
A knotter 2 is disposed immediately above the knotter, and a straight thread guide 8 is further disposed at an appropriate position above the guide portion. The test yarn standby mechanism 4 is formed in the shape of a flat tank, and has a large number of through holes 7 in the narrow horizontal surface of the top surface.
is arranged, communicates with the exhaust mechanism 6 through a flexible passage pipe at a part of the lower part, and moves horizontally in a predetermined direction in conjunction with a drive source, so that the through hole 7 is successively moved to a predetermined position. The upper surface on which the through hole 7 is arranged is arranged at the same level or slightly lower than the opening surface of the suction port 1.
Further, a series of guides 9 each having a corresponding guide 9 disposed at a predetermined distance above the through hole 7 is connected to the standby mechanism 4. A straight thread pressing mechanism 5 is disposed at a predetermined position from the straight thread guide 8 so that when the thread is pushed down, it approaches the suction port 1 and occupies a position corresponding to the guide of the knotter 2. The yarn transfer mechanism 3 is connected to a drive source, moves between the knotter 2 and the standby mechanism 4, and has an arm 10 connected to the rotational drive source, and when the arm 10 approaches the standby mechanism 4, By rotating in close contact with the yarn between the guide 9 and the through hole 7, the yarn is held in that part, and when the mechanism 3 moves and approaches the knotter 2, it holds the pressed down part of the straight yarn. The yarn is brought into close contact with the yarn, and then moved further and guided into the guide section of the knotter 2. Next, the connecting part of the knotter 2 is activated to connect the threads, and the excess connected part and the straight thread are cut near the suction port 1.
The structure is such that a new straight thread is formed and the same process is repeated thereafter.

As explained above, in the drum of the standby mechanism 4, the spatial extent is larger than that of the exhaust pipe, and each through hole is The suction force of the yarn 7 is equalized, and the ends of each yarn are stored in the tank through the through hole 7, and some of them are intertwined to create appropriate cushioning properties. Since the threads are connected to each other, an appropriate tension is applied to the yarn from each creel to the through hole 7, and the state is balanced against the frictional resistance at each guide, the yarn exit of the creel, the through hole 7, etc. can be easily adjusted by adjusting the displacement, and even if more than 90 yarns are placed adjacent to each other at around 1 cm apart, there will be no problem of entanglement or excessive loosening between them, and it is possible to handle many yarns at once. Articles can now be placed on standby. For the same reason, the moving distance of the standby mechanism 4 can be kept within about 90 cm, and the device itself can be significantly downsized. Furthermore, after the knotter 2 is activated by the suction port 1, the cut excess yarn is quickly and reliably removed from the vicinity, and at the same time, the beginning of the cut end of the straight yarn is also sucked into the standby mechanism 4. It became convenient because it could be maintained while imparting almost the same tension state. In addition, since the placement and replacement of each yarn could be limited to a predetermined location, which made it cheaper, the operation of each mechanism was simplified and control became easier, and the overall work area became extremely small.
