Abstract
The invention discloses a method for enabling breadths of fabric to be identical. The method includes the following steps: 1) memorizing yarn length and yarn tension; 2) comparing the yarn length and tension data; 3) feeding back signals to a control system; and 4) compensating and monitoring the yarn length. Breadths, length and weight of the fabric woven by identical machine and different machines keep consistent under closed loop control of an elastic yarn delivery device and a density motor on a density adjusting device and mixed with a control system meanwhile. The fabric woven by the different machines keeps consistent, and memorizing weaving can be achieved through methods such as network sharing and data copying. By means of quantitative control of used yarn, yarn waste is effectively reduced, and cost is saved. Meanwhile, the weaving requirement of the fabric is met.
Description
Technical field
The invention belongs to technical field of knitting machinery, particularly a kind of identical method of fabric width that makes fabric.
Background technology
Computer knitted machine is woven into garment piece with yarn when work, in theory, the garment piece of same style, same material, its used amount of thread should be identical, the weight of fabric also should be identical.But in fact, the fabric that different machines or uniform machinery different batches weave, its weight has certain deviation, and this just makes the fabric quality disunity, and the yarn waste takes place easily, can't satisfy the situations such as braiding requirement of fabric.
The applicant causes the main cause of this problem to be by discovering, to the defeated yarn process that enters braiding, its operating path is longer from the line tower for yarn, needs repeatedly tensioning; And yarn itself has certain elasticity, and the yarn that enters braiding is inconsistent because of rate of tension, so though to weave used length identical, weight is also inequality, thereby the fabric width of fabric, weight are also inequality.
Background technology
The objective of the invention is in order to address the above problem the identical method of the fabric width that makes fabric of provide a kind of effective minimizing yarn waste, saving cost.
For this reason, technical scheme of the present invention is: a kind of identical method of fabric width that makes fabric, and the permanent tension feedback of its involved cloth cover fabric system comprises control system, many knitting machines in one of control system control or the same workplace; All flexible yarn Thread-feeding device, density electrical machine and resolving encoder on every knitting machine; It is characterized in that: it may further comprise the steps:
1) memory length of yarn, yarn tension; First during braided fabric, utilize the elastic yarn feeding device to measure length and the tension force of single braiding unit yarn around yarn dish and tension pulley, the singlechip controller of recycling elastic yarn feeding device is remembered length of yarn, yarn tension;
2) length of yarn, tension data are compared; When carrying out next part weaving textile, the elastic yarn feeding device compares length of yarn, the tension data of length, tension data and the memory of current single braiding unit yarn;
3) signal feedback is arrived control system; When step 2) in length of yarn, tension force and memory length of yarn, tension force inconsistent, the elastic yarn feeding device feeds back to control system with signal output;
4) to compensation and the monitoring of length of yarn; When control system receives the unusual feedback signal of elastic yarn feeding device, control system is passed on the density electrical machine that gives on the density regulating apparatus with adjustment signal again, by closed-loop control realization real-time compensation and the monitoring to length of yarn of density electrical machine and resolving encoder.
The present invention is by the density electrical machine closed-loop control on elastic yarn feeding device and the density regulating apparatus, merges control system simultaneously and realizes keeping unified with the fabric width that weaves between machine and the different machines, length, weight.The fabric that weaves between the different machines keeps methods such as unification can be shared by network, data copy to realize the memory braiding.By to the quantitative control with yarn, effectively reduce the yarn waste, save cost, satisfy the braiding requirement of fabric simultaneously.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and embodiments of the present invention.
Fig. 1 is system flowchart of the present invention.
Embodiment
Referring to accompanying drawing.Present embodiment comprises control system, elastic yarn feeding device, density electrical machine and resolving encoder; Length of yarn and the yarn tension of single braiding unit measured and remembered to described elastic yarn feeding device, when failing yarn next time, the length of yarn data of current single braiding unit and the length of yarn data of memory compared; When the yarn data were inconsistent, the elastic yarn feeding device fed back to control system with signal output; Control system is passed on the density electrical machine that gives on the density regulating apparatus with adjustment signal more then, by closed-loop control realization real-time compensation and the monitoring to length of yarn of density electrical machine and resolving encoder.
