Abstract
The invention relates to an on-line detection device for a warp beam of a warp knitting machine. The on-line detection device comprises a support part and a detection part. The detection part comprises a rotary shaft, a shaft sleeve, two pressing wheels and a sensor, wherein a support shaft and a pressing shaft are movably connected by a bearing base, and both ends of an elastic element act on the support shaft and the pressing shaft respectively; the rotary shaft and the shaft sleeve are connected by a bearing sleeve, margins are reserved at both ends of the shaft sleeve respectively, the two pressing wheels are fixed on the marginal positions at both ends of the rotary shaft respectively, and the shaft sleeve is movably connected with the circumference of the pressing shaft; and a signal output end of the sensor is connected with an input end of a computer control system of the warp knitting machine. The on-line detection device has the advantages of simple structure, accurate and stable detection and suitability for intelligent and automated warp knitting machine-controlling systems, and can also meet the modernized high-speed and high-precision production requirements.
Description
Technical field
The present invention relates to a kind of on-line measuring device, be specially adapted in the warp let-off control system of warp knitting machine.
Background technology
At present, the warp let-off control system of domestic warp knitting machine is mainly mechanical warp let-off control system and EBA electronic let-off control system, right this mechanical type warp-feeding mechanism exists mechanical complicated maintenance operation very inconvenient, frequently will be by people's wage adjustment warp run-in, and shortcomings such as the fabrics cloth cover uniformity is poor, speed is slow, easily broken yarn, noise be big, belong to low-and-medium-grade products, can not adapt to the high-quality requirement of modern industry far away.And existing EBA electronic let-off control system is open cycle system substantially, main rely on input through the axle parameter, wait the theoretical outer perimeter that calculates through axle as outer perimeter, interior girth, the number of turns, by progressively improving the influence that outer perimeter diminishes and brings after the rotating speed of axle remedies yarn consumption, thereby reach the purpose of constant warp run-in.But, owing to data computing is subject to warping tension force reason, the measure error reason, parameter update reason, warping condition, the user uses the influence of many reasons such as raw material, substantially can't realize accurate Calculation, differing that error amount has can reach more than the 5%-10%, thereby the error that causes system's warp run-in is also more than 5%-10%, thereby easily cause faults such as device damage, knitting needle rupture, fabric is scrapped, can not satisfy the middle and high-end market demand; Also have some modified let-off motions both at home and abroad, adopt machinery to adjust yarn tension, electronics electric shock switch FEEDBACK CONTROL machine switch, but these all can not realize functions such as error quantization adjustment, automatic Compensation Regulation, so can not realize and satisfied modernization high speed, high-precision requirement.
Summary of the invention
The objective of the invention is problem, provide a kind of simple in structure, detect accurate, stable on-line measuring device at detection means deficiency in the existing warp knitting machine warp let-off control system.
For achieving the above object, technical scheme of the present invention is: a kind of on-line measuring device that is used for warp knitting machine through axle, comprise support section and test section, and described support section comprises: fulcrum, last item and flexible member; Described test section comprises rotating shaft, axle sleeve, two pinch rollers and sensor; Wherein, flexibly connect by bearing block between fulcrum and the last item, and the flexible member two ends act on fulcrum and last item respectively; Described rotating shaft links to each other by the bearing socket with axle sleeve and leaves surplus respectively at the axle sleeve two ends, and described two pinch rollers are separately fixed at the residue position at rotating shaft two ends, and described axle sleeve and last item circumferentially flexibly connect; The signal output part of described sensor links to each other with the input of the computer control system of warp knitting machine.
As the preferred embodiments of the present invention: described fulcrum, the last item structural design that meets at right angles, described flexible member is a torsion spring.
Described sensor is a pulse transducer, and its receiving terminal and transmitting terminal are separately fixed on pinch roller and the axle sleeve.
When the present invention uses on the one hand by support portion fixes on the warp knitting machine lathe, act on the coiled hair yam surface by pinch roller on the other hand, rotation by pinch roller produces pulse signal quantity and feeds back computer control system in warp knitting machine, computer control system calculates in conjunction with pinch roller foreign steamer girth that yarn is actual to go out yarn length, and make comparisons with the warp let-off length of yarn of theory setting and to draw the numerical compensation warp run-in, thereby back control servomotor reaches the full cut-off ring control purpose of constant warp run-in.The present invention designs small and exquisite, is not subjected to spatial constraints, and can be according to being provided with arbitrarily through number of axle amount and needs; Stability Analysis of Structures of the present invention is measured accurately, can be used for realizing in the warp let-off control system of warp knitting machine full cut-off ring, the purpose of compensation automatically.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is practical state diagram of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment: as shown in Figure 1: the present invention relates to a kind of on-line measuring device, be used for the warp let-off control system of warp knitting machine.It comprises support section and test section, and support section comprises: fulcrum 5, last item 4 and torsion spring 6; The test section comprises rotating shaft 2, axle sleeve 3, two pinch roller 1 and pulse transducers; Flexibly connect by bearing block 8 between fulcrum 5 and the last item 4, and torsion spring 6 is socketed on the fulcrum 5 and by clamp ring the one end is fixed the elastic force that also can regulate torsion spring by the fixed position of clamp ring, its other end then acts on and is fixed on the last item 4; 3 on rotating shaft 2 and axle sleeve link to each other by bearing 7 sockets, and described rotating shaft 2 is longer than axle sleeve 3 and is left surplus respectively at axle sleeve 3 two ends, 1 residue position that is separately fixed at rotating shaft 2 two ends of two pinch rollers; Axle sleeve 3 circumferentially flexibly connects with last item 4, can guarantee all the time that two pinch rollers 1 are close to the coiled hair yam surface; Pulse transducer is selected DK type pulse transducer for use in the present embodiment, and the DK device can produce 1 or 5 pulse/rotations, and transmission and receiving terminal can be installed in respectively on pinch roller 1 and the axle sleeve 3; According to the precision needs, also can select photoelectric sensor etc., and the signal output part of sensor links to each other with the input of warp knitting machine computer control system.As shown in Figure 2, when the present invention moves, the support section of on-line measuring device is fixed on the wallboard 11 by bearing 9, act on coiled hair 12 yam surface by pinch roller 1 on the other hand, the reality that the pulse signal quantity that provides according to pulse transducer and the outer electrical path length of pinch roller can calculate the coiled hair yarn is length high-volume.
The present invention is simple in structure, detects accurately, stablizes; Be applicable in the warp knitting machine control system of intellectuality, automation, satisfy modernization high speed, high-precision production requirement fully.
