Abstract
The invention discloses a cloth cover fabric constant tension feed-back system. The cloth cover fabric constant tension feed-back system comprises a control system, wherein the control system controls one or more knitting machines in the same working place. Each knitting machine is provided with an elastic yarn delivering device, a density motor and a rotary transformer encoder. The elastic yarn delivering device comprises a single chip microcomputer, a yarn winding disc and a tension disc, is provided with at least one yarn winding disc sensor and a tension sensor which are connected with the single chip microcomputer, and the single chip microcomputer is connected to the control system in a one-way mode. The control system is in one-way connection with the density motor. The rotary transformer encoder monitors the density motor and is in one-way connection with the control system. The cloth cover fabric constant tension feed-back system effectively reduces yarn waste and saves the cost by performing quantitative control of the yarn using amount and meanwhile meets the knitting requirements of textiles.
Description
Technical field
The invention belongs to technical field of knitting machinery, particularly the permanent tension feedback of cloth cover fabric system.
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 permanent tension feedback of the cloth cover fabric system that a kind of effective minimizing yarn waste is provided, saves cost.
For this reason, technical scheme of the present invention is: the permanent tension feedback of cloth cover fabric system, and it is characterized in that: it 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; Described elastic yarn feeding device comprises single-chip microcomputer, around yarn dish and tension pulley, and have at least one around yarn dish sensor and tension pick-up, be connected with described single-chip microcomputer, single-chip microcomputer is the unidirectional control system that is connected to again; The unidirectional Connection Density motor of described control system; Described resolving encoder monitored density motor, and unidirectional connection control system.
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 present invention is in braided fabric process first, and the elastic yarn feeding device can be remembered length of yarn, the yarn tension of single braiding unit.When carrying out second or next part weaving textile, the elastic yarn feeding device is to the length of yarn of current single braiding unit, the length of yarn of tension data and memory, tension data compares, if current length of yarn, tension force and memory length of yarn, tension force is inconsistent, the elastic yarn feeding device arrives control system with signal feedback, 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 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 fail yarn next time then, 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.
