Abstract

The invention provides a method for achieving flexible control of feed amount by carrying out time-sharing control on feed by a clutch feed mechanism. Time sharing is carried out on one feed cycle by changing the clutch control method in the feed control process, thus controlling pull-in and disconnection of clutches on shafts with different rotating speeds, more optional changes of the feed amount are achieved by driving combination of feed rollers by the shafts with different rotating speeds in a time sharing manner, for example, hundreds of changes of the feed amount can be achieved by the feed mechanisms of two clutches in each group according to the control requirements, and the clutch switching frequency is reduced by optimizing the state switching strategy. By adopting the method provided by the invention, the defects of the prior art are overcome; on the basis of existing clutch feed mechanisms, through time-sharing control on on-off of the clutches, the feed amount can be flexibly controlled and the clutch state switching frequency is furthest reduced. The method is applied to textile jacquard and can guarantee more circle height/pile height changes of original types in one jacquard cycle.

Description

The yarn feeding of clutch yarn-feeding device Time-sharing control realizes controlling yarn feeding metering method flexibly

Technical field

The present invention relates to a kind of clutch height control that improves and realize the flexible method controlling yarn feeding amount, belong to textile weaving technical field.

Background technology

Clutch yarn-feeding device height control makes suede yarn form pile loop at the base cloth back side with the do action of yarn feeding-hook yarn-de-yarn, and period, single cycle yarn feeding amount determines pile loop height substantially.Controlled by clutch yarn-feeding device to carry out a next state switching within a jacquard weave cycle, this method limits the adjustable flexibility of yarn feeding amount in the past, and to realize yarn feeding amount kind only consistent with clutch number in clutch pack for this structure usually.

In conventional clutch jacquard weave combined mechanism, a combination is made up of 2,3,4,5 clutches usually, and often in group, each clutch is arranged on the axle of a different rotating speeds.Tradition jacquard weave process will switch a next state a start time in jacquard weave cycle, make clutch pack within the current jacquard weave cycle, only have a clutch to keep adhesive, thus the pattern wheel that clutch pack is driven have the rotating speed of adhesive clutch place axle.When not considering yarn slippage, can obtain a jacquard weave cycle feeding yarn line length according to rotating speed and radius parameter, in such one group of clutch pack, clutch number just limits yarn feeding amount change kind in the same jacquard weave cycle.Correspondence often organizes clutch number 2,3,4,5 in clutch pack, its yarn feeding amount change kind optional quantity is 2 respectively, 3,4,5 kind.

Summary of the invention

The technical problem to be solved in the present invention, by the make-and-break time of Time-sharing control clutch, realizes with the change of the more yarn feeding amount of Clutch Control less in clutch pack, make to obtain under same hardware condition more multi-turn high/suede High variation may.

In order to solve the problems of the technologies described above, technical scheme of the present invention is to provide a kind of clutch yarn-feeding device Time-sharing control yarn feeding and realizes controlling yarn feeding metering method flexibly, it is characterized in that: the method is made up of following 4 steps:

Step 1: establish a total n axle, is divided into n-1 yarn feeding amount region, n be greater than 1 integer; Each axle is according to axle rotating speed height sequencing numbers, and the larger mean speed of axle sequence number is lower, according to the amount of each axle monocycle yarn feeding of formulae discovery below:
