Abstract
The utility model discloses a servo system applied on a gripper loom. The servo system comprises an electronic let-off mechanism and an electronic curling mechanism, wherein the electronic let-off mechanism consists of a tension signal acquisition system, a signal processing and control system and a beam drive device; and a servo motor drives a beam through a worm gear so as to control the let-off speed, thus realizing the automatic control on constant tension and keeping the tension to be even during the process that the beam becomes smaller. The system has excellent cost performance.
Description
Technical field
The utility model relates to a kind of servo-drive system that is applied in Rapier looms.
Background technology
Rapier looms belongs to a kind of of shuttleless loom, is one of leading type of giving priority to of China's textile machinery industry.New loom accounted for the loom sum and accounted for more than 20% in the main textile production in the world state early 1990s, and wherein weaving big country in West Europe all reaches more than 70% as Italy, France.And China's shuttleless loom ratio is very low, and market also needs to transform the Rapier looms of large quantities of low grades, so, see that for a long time market is very tempting.But we notice, because raw material appreciate and from the mid-term in 2007 of factor affecting such as appreciation of the RMB so far, difficult test is being stood in frame market.Originally lower profit margin seems under the background of dull sale than whenever all severe, so the mode that reduces cost is actively being sought by each loom manufacturer.Under the situation that this year, iron ore price significantly promoted again, machine cost reduces and has probably become a kind of wonderful dream, so electric-control system improves, will become effective a kind of approach.
Summary of the invention
The utility model: a kind of servo-drive system that is applied in Rapier looms is characterized in that comprising: electronic warp feeding mechanism, electronics coiled body; Described electronic warp feeding mechanism is made up of tension signal acquisition system, signal PIAPACS, beam of a loom drive unit three parts; Described tension signal acquisition system includes pressure sensor, and two back rest are provided with this pressure sensor.Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of novel gripper loom, with its high speed, fabric width, high-quality, characteristics such as varietal adaptation is strong and noise is low, be subjected to liking of users deeply.It is advantageous that: 1, varietal adaptation is strong.Rapier looms is good to the many varietal adaptations of production small lot.Cotton, hair, silk, fiber crops can both be knitted on the Rapier looms, and fit and knit BLENDED FABRIC, and particularly the self-figure yarn-dyed fabric has unique advantage.2, speed is fast, the efficient height.Rapier looms is gone into latitude rate height, and rotating speed is fast, the yield per unit area height.Medium-grade model just can reach 300-500r/min, high-grade type even arrive more than the 800r/min.With the Rapier looms is the novel shuttleless loom of representative, broken in the past restriction by raw material type " cotton, hair, silk, fiber crops " industry product, generate the exploitation of blending, interweaving product and the new and high technology fiber product of multiple fiber, making the industry textile product press close to ability to market increases, supply falls short of demand for the new product that adapts to fashionable, that designs and varieties are satisfied the need, and the medium and high-grade goods outlet is good.This servo-drive system that is applied in Rapier looms is characterized in that comprising: electronic warp feeding mechanism, electronics coiled body; Described electronic warp feeding mechanism is made up of tension signal acquisition system, signal PIAPACS, beam of a loom drive unit three parts; Described tension signal acquisition system includes pressure sensor, and two back rest are provided with this pressure sensor.
Servo-drive system is occupied heavier position in the electric-control system of whole Rapier looms, this is embodied in servo action and two aspects of price.Electronic warp feeding and electronic take-up device were to make optional component (especially electronic take-up) in the past, were specified by the user, and along with the raising of loom speed and motor, electronic sensor performance, external high-grade Rapier looms all disposes as standard component over nearly 10 years.Finish by servo-drive system just and electronic warp feeding and electronics are curling.
Rapier looms is finished through needing interweaving of, weft yarn and just can be accomplished by carrying palm fibre, wefting insertion, beat up, the warp let-off, organic cooperation and other auxiliomotor cooperations of five big motions such as batching.Also have warp stop motion, crapand automatic stop, weftsupplying motion to wait the synkinesia of controlling by auxiliary body for (shuttle changing) in addition.Whole service process control complexity, should realize that loom startup, parking, stop over, latitude stop and basic function such as automatic latitude seeking, simultaneity factor is regulated the rotating speed of let-off motor and reel-motor again respectively by servo controller by let-off motor, reel-motor, deceleration system, servo controller, tension pick-up and associated mechanisms, keeping the desired filling density of fabric, and guarantee constant tension.
Control circuit is core with PLC, or replaces with single-chip microcomputer.Mainly introduce below and closely-related electronic warp feeding of servo-drive system and electronic take-up mechanism.Electronic warp feeding mechanism is made up of tension signal acquisition system, signal PIAPACS, beam of a loom drive unit three parts.The pressure sensor that is contained on two back rest detects warp surface tension, PLC detects the tension feedback signal at ordinary times, signal is controlled our servo-drive system after the PLC inter-process, servomotor drives on the beam of a loom by worm and gear, control warp let-off speed, thereby realize the automatic control of permanent tension force, guarantee to keep even tension in the beam of a loom process from large to small.Figure below is electronic warp feeding structural scheme of mechanism (Fig. 1).This kind is applied in the servo-drive system of Rapier looms, it is characterized in that comprising: electronic warp feeding mechanism, electronics coiled body; Described electronic warp feeding mechanism is made up of tension signal acquisition system, signal PIAPACS, beam of a loom drive unit three parts; Described tension signal acquisition system includes pressure sensor, and two back rest are provided with this pressure sensor.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are: thus realize the automatic control of permanent tension force, guarantee to keep even tension in the beam of a loom process from large to small; Simultaneously, the whole system price lowers greatly.

Fig. 2 is a servo-drive system electronic take-up structural scheme of mechanism.Among Fig. 1,1 is through axle, and 2 is gear, and 3 is bevel gear, and 4 is worm and gear, and 5 is servomotor; Among Fig. 2,1 is winding off spindle, and 2 is electronic take-up, and 3 is bevel gear, and 4 is sprocket wheel, and 5 is synchronous pulley, and 6 is decelerator, and 7 is servomotor.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
