Abstract
The utility model provides a detection and control device of warp fracture or warp winding on a weaving machine. The detection and control device comprises a weaving machine frame, an emission mechanism and a processing mechanism, wherein the emission mechanism and the processing mechanism are arranged on the weaving machine frame and mutually correspond, the emission mechanism is connected with the processing mechanism through a circuit, the emission mechanism comprises a laser emitter and a lens, and the processing mechanism comprises a sensor, a signal processing unit and a stopping signal output unit. The detection and control device is detected in pixel mode, simple in structure, low in cost, high in detection precision, and low in the missing detection rate; and due to the fact that parallel light sources belong to regional detection, the detection region is large, occasions of the warp fracture or the warp winding on the weaving machine can be effectively detected, and economical loss of a textile mill is reduced.
Description
Technical field
The utility model relates to a kind of checkout gear, the detection and the control device that on especially a kind of loom warp break or warp are twined.
Background technology
In the present textile mills, loom is in operation process, and warp, weft yarn are in abnormal working condition sometimes, therefore form residual defect at fabric, affect the quality in kind of fabric.In order to overcome the above problems, many enterprises can be provided with Warp stop motions at loom.
Described Warp stop motions can make the self-stopping device of loom when certain root warp end break or when too lax when weaving on looms thing.There has been this device can prevent at the scarce warp of fabric formation, through float such as contracting and skips, fabric quality is improved to some extent, and the weaver does not need often watching attentively warp thread, thereby can reduce labor intensity, increase the grandstand ability, and the productivity ratio of loom is increased.Warp stop motions can make loom be parked on certain main spindle's, sends simultaneously the cracked ends index signal, adopts weft detector to come the fracture of detection line.Common Warp stop motions has electric and mechanical type two classes, and shuttleless loom uses the former usually, and fly-shuttle loom uses the latter.Warp end break electric automatic stop arrangement has two kinds of contact and photo-electric types.The electric automatic stop arrangement of advanced technology is carried out very timely, accurately parking action by microcomputerized control to warp end break or warp thread overrelaxation.At present, the electric automatic stop arrangement of contact warp end break with microcomputerized control uses comparatively general at shuttleless loom.
In actual production, the shortcomings such as above Warp stop motions has that investment is large, cost is high, complicated operation, maintenance inconvenience and maintenance cost height, in addition; the detection accuracy of present Warp stop motions is low; usually undetected situation can occur, therefore, larger on the impact of enterprise.
The utility model content
The purpose of this utility model is to provide a kind of a kind of cost that detects and control for fracture on the warp or winding low for the deficiency that solves above-mentioned technology, simple to operate, the detection and the control device that on the loom easy to maintenance warp break or warp are twined.
In order to achieve the above object; the detection and the control device that on the designed a kind of loom of the utility model warp break or warp are twined; it comprises loom frame, trigger mechanism and processing mechanism; described trigger mechanism and processing mechanism are arranged on the loom frame; and mutually corresponding; described trigger mechanism is connected setting with processing mechanism by circuit; described trigger mechanism comprises generating laser and lens, and described processing mechanism comprises sensor, signal processing unit and stopping signal output unit.In this structure, form the laser parallel light source behind the light source scioptics that generating laser sends.
As preferably, described sensor adopts the linear CCD sensor, and described sensor length is less than the length of source of parallel light; The design of this structure is in order to alleviate the loom vibrations to the impact of sensor.
As preferably, described generating laser is selected the laser parallel light source greater than ccd sensor detection faces length.
The detection and the control device that on the resulting loom of the utility model warp break or warp are twined; trigger mechanism is arranged on a side of loom; opposite side at loom is provided with corresponding with it processing mechanism; in the process of warp weaving; detector starts according to the loom hall signal: when warp is opened up and down it is detected; and the warp closed type stops to detect up and down; under normal circumstances; warp can not overlap; therefore, a side of sensor can not receive fracture or the living shade signal of warp shade fecund, if when detector detects; the many signals of shade have been received on the sensor; then expression has the generation of hidden danger, and this signal is transferred to signal processing unit, transfers signals to the stopping signal output unit by signal processing unit thereupon; whole loom sent instruction, stop to weave cotton cloth.Checkout gear of the present utility model is pixel and detects, and simple in structure, cost is low, accuracy of detection is higher, and loss is low, detects because source of parallel light belongs to the zone, therefore detection faces is larger, can effectively detect fracture or the winding of warp on the loom, has reduced the economic loss of textile mills.
Description of drawings
Fig. 1 is structural representation of the present utility model.
