Description

Sample warper with displaceable yarn guide

The present invention relates to a new sample displaceable yarn guide with a displaceable yarn guide capable of pattern image by multiple number simultaneous image according to preset pattern data (a yarn arrangement order, a color yarn arrangement order).

As a sample warping machine conventionally used, for example, the pattern data set in advance using a structure disclosed in Japanese Patent No. 1529104, that is, a fixed creel which erects a plurality of bobbins wound with different types (different colors or twists) yarns It is known that yarns are wound on a canonical drum by yarn guides while yarn exchange is performed by a yarn selector according to the yarn order.

In addition, by using the rotary krill, the process of replacing the yarns can be omitted, eliminating any time loss during yarn replacement, and it is also possible to simultaneously wind the yarns of the plural number of yarns into the canon drum, and also to shorten the canon working time. Also known are sample warps capable of simultaneous numbering of double-numbered copies (Japanese Patent No. 1767706, US Patent No. 4,972,662 and European Patent No. 375480).

The fixed krill has a plurality of bobbins wound around the same kind and / or different kinds of yarns (mainly different kinds of yarns). There is an advantage that can work the canon, but there is a disadvantage that it takes a long time for the canon to wind one yarn in a canon drum. On the other hand, the rotary krill has a plurality of bobbins wound around the same type and / or different types of yarns, so that a designated point (for example, one color of red yarn) and one to one (for example, one red and one white) Very limited, such as repetition of 1 repetition of 1 S and 1 Z, 2 to 2 (for example 2 repetitions of 2 enemies and 2 whites, and 2 repetitions of S and 2 Z) It can be used to repeat the pattern. This rotary krill has the disadvantage that it is impossible to perform the canoning of the pattern canon other than a limited pattern canon, but there is an advantage that the canon time is drastically shortened to wind the yarn of a double number on the canon drum at the same time.

In the conventional sample warping machine, one or more yarn guides rotatably and radially mounted on the front surface of the warp drum, fixed krill and / or rotary krill provided in correspondence with the yarn guides, and yarns It was to make the basic selection device which performs the exchange of the yarn supplied to the guide as an essential basic structure.

On the other hand, there is also proposed a pattern warp partial warp that allows the winding of the yarn and the winding of the yarn without using the yarn selection device (Japanese Patent No. 3263050 and Japanese Patent Laid-Open No. 2002-212851). There was a problem that the yarn was unnecessarily consumed or the yarn was not smoothly exchanged with the cold stop.

MEANS TO SOLVE THE PROBLEM This inventor reached | attained this invention as a result of repeated research in order to develop the sample apparatus which has the novel mechanism which solved the said problem.

The object of the present invention can omit the conventional installation of the yarn selection device, eliminate unnecessary consumption of the yarn at the time of winding down the yarn, and exchange the winding of the yarn and the winding stop of the yarn very smoothly, The present invention provides a sample warp with a displaceable yarn guide, which enables the cane to be polished efficiently in a short time.
