Description
Technical field multi-bar jacquard warp knitting machine is a kind of with braiding spandex high-tension lining, and lace is main high-grade textile machine.
The present warp knitting machine manufacturing enterprise of technical background China can only generate mechanical type multi-bar jacquard warp knitting machine, and the sley bar number at most only reaches 8 sley bars.And models such as the mechanical type multi-bar jacquard warp knitting machine of KARL MALIMO company such as MRSS56/42, its sley bar number is respectively 56 and 42, and the sley bar number is far more than 8 sley bars.And the multi-bar of computer control at present jacquard warp knitting machine, the only German Carl maya in whole world company can make (mechanical type multi-bar jacquard warp knitting machine also has only German Carl maya company that manufacturing is just arranged), and every price is many about ten thousand yuan of 160-400.As models such as the computer control multi-bar jacquard warp knitting machine of the KARL MALIMO company of selling on the market such as MRSS56/42, then by the programme-control sley bar displacement of computer braiding, therefore cancelled the mechanical chain piece, colored type of conversion only must can change colored type about five minutes like this, change big also need only about 20 minutes, improved the market adaptability greatly.But the executing agency of this machine is similar to the mechanism that mechanical type multi-bar jacquard warp knitting machine eccentric wheel drives slide block.Be not completely free of the design feature of former mechanical type board; restoring force by back-moving spring makes sley bar realize counteragent; thereby strengthened the resistance of positive movement; the wearing and tearing of member have been aggravated; and lean on eccentric wheel to promote the mode of slide block; frictional resistance is also big; the rotating speed that one board changes with per minute 350; the per minute sley bar will move 350 times; general board is class Three's operation, must move so frequent motion every day 50.4 ten thousand times; whole transmission mechanism will lean on good lubricating to reduce abrasion; and turn round continuously when board; keeping mechanical component, constant it is gone slick under certain thermal deformation and oily temperature, in case shut down when starting shooting more than one hour, tends to that machine works can not be normal for some time again; after treating that the distortion of oily temperature and mechanical component is stable, just operation freely.We studies show that this mechanism exists that positioning accuracy is poor, the member abrasion are big, reaction speed waits shortcoming slowly.And the action of its inverted orientation is by the back-moving spring pulling, and this pulling force reaches hundreds of N (tens of kilogram), and this power is added on the transmission mechanism always, has strengthened the load of carrying out transmission, has therefore aggravated machine members.Also exist reaction speed to wait many shortcomings slowly.
The transmission mechanism that the purpose of this invention is to provide a kind of multi-bar jacquard warp knitting machine, but the drive motors with the closed-loop control of travel point position drives the kind of drive that ball screw adds encoder feedback, thoroughly overcome back-moving spring and be added in resistance on the motion, reduced the friction and wear of member, developed one and overlap the sley bar high speed that is fit to the multi-bar jacquard warp knitting machine, frequent, accurate, reliable transmission mechanism.
Summary of the invention the invention provides a kind of transmission mechanism of multi-bar jacquard warp knitting machine to achieve these goals, and this mechanism is by base, ball screw, ball screw nut, but the drive motors of travel point position closed-loop control, coupler, absolute encoder, the member of sley bar and platform are formed.Wherein base is a matrix, the matrix both sides are the bearing groove seat, ball screw is installed on the bearing groove seat, the extended part of ball screw is equipped with a coupler, but this coupler joins with the drive motors that is fixed on the travel point position closed-loop control on the base extension, the another one coupler but the other end of the drive motors of travel point position closed-loop control joins, this coupler and absolute encoder join, encoder is fixed on the base extension, warp knitting machine sley bar member is fixed on the nut of ball screw, when but the drive motors of travel point position closed-loop control rotates, driving ball screw by coupler rotates, the sley bar that is fixed on the jacquard warp knitting machine on the nut is moved laterally, produce the motion of braiding flower type.In the process of self-figure, sley bar will be in the action of the position of regulation, the feedback to position probing of absolute encoder, can accurately locate the controllable motor position, thereby realize the accurate location of ball screw position, the braiding of required colored type style is finally finished in the accurate location of promptly realizing sley bar.
Because the kinematic parameter of flower type, the work section of ball screw is all in continuous variation, and these factors are all favourable to reducing friction, and positioning accuracy can reach ± and 0.0075mm, reaction speed can reach 0.08s/10mm.And the technical indicator of the computer jacquard warp knitting machine of German Carl maya company only reaches positioning accuracy 0.15mm, and reaction speed is also low.But with the drive motors of travel point position closed-loop control, roll close-loop control scheme that strain screw mandrel, accurate encoder form, have an enormous advantage than the eccentric sheave piece rotating mechanism mode that the computer control jacquard warp knitting machine of West Germany Ka Er Meyer company adopts.
Appended drawings is the schematic diagram of the transmission mechanism of multi-bar jacquard warp knitting machine.
The present invention is described in further detail below in conjunction with drawings and embodiments for the specific embodiment.
Because the kinematic parameter of flower type, the work section of ball screw is all in continuous variation, these factors are all favourable to reducing friction, the control system of multi-bar jacquard warp knitting machine requires to act frequently (move about 500,000 times per working day), (positioning accuracy about every 10mm/1ms) at a high speed, accurately (about 0.015mm), reliably (misoperation may cause breaking all weaving warps, and nearly 2000 pins) characteristics, the invention provides a kind of transmission mechanism of multi-bar jacquard warp knitting machine, this mechanism is by base 1, ball screw 2, ball screw nut 3, but the drive motors 4 of travel point position closed-loop control, coupler 5, absolute encoder 6, sley bar member 7 is formed.But the drive motors of the travel point position closed-loop control of the embodiment of the invention is to adopt the controllable motor of stepper motor or servomotor to drive ball screw 2 rotations, rotatablely moving of this controllable motor is converted into the rectilinear motion of ball screw nut 3, with the laterally action back and forth of sley bar on the rectilinear motion realization warp knitting machine sley bar member 7 of ball screw nut 3, realize the process of sley bar self-figure.Sley bar will be in the action of the position of regulation, and will execution exactly in official hour, misoperation can not be arranged or move phenomenon not in place, otherwise can't knit out desirable colored type, so this mechanism is by the feedback to position probing of absolute encoder 6,, thereby realize the accurate location of ball screw nut 3 positions to the accurate location of controllable motor position, promptly realize the accurate location of sley bar, finally finish the braiding of required colored type style.Can reach positioning accuracy ± 0.0075mm, reaction speed 0.08s/10mm.And the technical indicator of the computer jacquard of German Carl maya company also only reaches: positioning accuracy 0.15mm, reaction speed is also low.For the reasonability that guarantees to design, carried out correlation test at permanently happy prosperous Fabritex S.r.l scene and shown above-mentioned analysis result.Single technical indicator that reaches in joint, the pilot scale model machine of combing in test is: positioning accuracy ± 0.0075mm, reaction speed 0.08s/10mm.Machine maintenance master worker reflection in the test at the scene: the technical indicator of the computer jacquard of KARL MALIMO company also only reaches: positioning accuracy 0.15mm, reaction speed is also low.When therefore demonstration is checked and accepted at the scene, be located precision by 0.015mm, the reaction time presses 0.12s and revises design.Before demonstration is checked and accepted, hold completely this mechanism is existing, the demonstration course of receiving has reflected this confidence.This design organization is because the bidirectional self-locking of stepper motor power surely, removed tens kilograms the axial load that back-moving spring produces from, alleviated wearing and tearing, and littler because roll strain screw mandrel and the transmission of rolling guide rail abrasion, thereby its theoretical life-span is far above the product of West Germany Ka Er Meyer company.
The utility model is not limited to above-mentioned structure, is equally applicable to other structure, as long as utilized above-mentioned composition member, all belongs to the scope of the utility model protection.
