Abstract

The utility model discloses a device for automatically tracking a selvage and marking during detection of fabric defect. The device is characterized in that an A-position diffuse reflection switch and a B-position diffuse reflection switch are respectively fixed on the two ends of a switch fixed plate, and the switch fixed plate is arranged on a mounting plate; a label valve is also arranged on the mounting plate connected to a movable slide block of an air cylinder, and a directional control valve is connected to the two ends of the air cylinder through an air pipe, the A-position diffuse reflection switch and the B-position diffuse reflection switch are connected with a control system through a signal cable, and the directional control valve is connected with the control system through a controlling cable. The device provided by the utility model has the beneficial effects that a defect position is marked on the selvage of a cloth so as to provide convenience for the subsequent operation, and the operation efficiency is greatly improved.

Description

A kind of device of following the trail of selvedge when detecting fabric defects automatically and doing to indicate

Technical field

The utility model belongs to textile detection technique field, relates to a kind of device of following the trail of selvedge when detecting fabric defects automatically and doing to indicate.

Background technology

Fault on the fabric is the key factor that influences the cloth quality.The arranging process of textile enterprise is used to check, repair the fault on the cloth cover, improves the cloth quality, at present manual type is adopted in the check of cloth, and this operation labor intensive is many, and the speed of artificial perching is slow, loss is high, the check continuity is low.Along with the continuous rising of human cost and textile enterprise to the improving constantly of cloth quality requirements, change this traditional artificial perching mode and become a kind of trend.

Summary of the invention

The purpose of this utility model provides a kind of device of following the trail of selvedge when detecting fabric defects automatically and doing to indicate, and the speed of perching is fast, and loss is low, check continuity height.

The technical scheme that the utility model adopted is, a kind of device of following the trail of selvedge when detecting fabric defects automatically and doing to indicate, A position diffuse reflection switch and B position diffuse reflection switch are separately fixed at the two ends of switch fixed head, the switch fixed head is arranged on the installing plate, the mark valve also is arranged on the installing plate, installing plate is connected on the moving slider of cylinder, directional control valve is connected the cylinder two ends by tracheae, A position diffuse reflection switch, B position diffuse reflection switch are connected with control system by signal cable, and directional control valve is connected with control system by umbilical cable.

Feature of the present utility model also is to be stretching structure between the two ends, the switch fixed head left and right sides, apart from scalable, can guarantees that mark can indicate on the selvedge from the motion tracking selvedge between the two ends, the left and right sides.

The beneficial effects of the utility model are to search mark for solving in the corresponding selvedge position of fabric defect position, the device that a kind of automatic tracking selvedge is provided and has done to indicate; Adopt CCD camera scanning cloth cover image, discern various harmful fault on the cloth cover automatically according to the Computer Vision Recognition technology, and near fault, give mark.Find mark fault when making things convenient for the subsequent repair cloth cover, need to do one and search mark in the selvedge position of corresponding fabric defect position.When the perching device recognizes fabric defect, do one at the selvedge of relevant position and indicate, show that there is fabric defect in this position of cloth, the mending workman opens folding cloth in this position, finds the fabric defect mark easily, place under repair.The effect of this device is to have indicated the position that has fault at the selvedge of cloth, for follow-up work provides convenience, has significantly improved work efficiency.

Description of drawings

Fig. 1 is automatic tracking selvedge of the present utility model and the apparatus structure synoptic diagram of making sign.

Fig. 2 is to use constitutional diagram.

Among the figure, 1. directional control valve, 2. cylinder, 3. mark valve, 4.A position diffuse reflection switch, 5.B position diffuse reflection switch, 6. moving slider, 7. installing plate, 8. switch fixed head, 9. control system, 10. tracheae, 11. signal cables, 12. umbilical cable, 13. cloth.

Embodiment

The device that the utility model is a kind of to be followed the trail of selvedge when detecting fabric defects automatically and do to indicate, structure as shown in Figure 1, A position diffuse reflection switch 4 and B position diffuse reflection switch 5 are separately fixed at the two ends of switch fixed head 8, between the two ends, switch fixed head 8 left and right sides apart from scalable, thereby regulate spacing between A position diffuse reflection switch 4 and the B position diffuse reflection switch 5.Switch fixed head 8 is arranged on the installing plate 7, and mark valve 3 also is arranged on the installing plate 7, and installing plate 7 is connected again on the moving slider 6 of cylinder 2.Directional control valve 1 is connected cylinder 2 two ends by tracheae 10, moving slider 6 move left and right on the control cylinder 2.A position diffuse reflection switch 4, B position diffuse reflection switch 5 are connected with control system 9 by signal cable 11, and directional control valve 1 is connected with control system 9 by umbilical cable 12.

User mode of the present utility model, as shown in Figure 2, cylinder 2 is installed in cloth 6 motion vertical directions, and A position diffuse reflection switch 4 and B position diffuse reflection switch 5 detect the position of cloth 13 selvedges in real time, feed back signal to control system 9, control system 9 control directional control valves 1 are opened, and directional control valve 1 is connected cylinder 2 two ends by tracheae 10, control cylinder 2 moving slider move left and right, drive mark valve 3 and move to position, cloth limit, if find fault, 3 actions of mark valve indicate at selvedge.

Cloth 13 moves up and down during work, skew about the meeting simultaneously, at first control system 9 control directional control valves 1 work, cylinder 2 right-hand member air inlets, moving slider 6 drives mark valve 3 and is moved to the left, when moving to the selvedge position, A position diffuse reflection switch 4 detects the cloth cover signal, feeds back to control system 9, control system 9 control directional control valves 1 quit work, cylinder 2 right-hand members are died, and mark valve 3 stops to move, and are parked on the selvedge position.If selvedge is offset left, then A position diffuse reflection switch 4 detects less than the cloth cover signal, then directional control valve 1 work, control cylinder 2 right-hand member air inlets, moving slider drives mark valve 3 and is moved to the left, and detects the cloth cover signal once more up to A position diffuse reflection switch 4, stops at the selvedge position.Opposite, if cloth 13 is offset to the right, then B position diffuse reflection switch 5 also detects the cloth cover signal, control system 9 control directional control valves 1 work this moment, cylinder 2 left end air inlets, moving slider 6 drives mark valve 3 and moves right, when B position diffuse reflection switch 5 detects less than the cloth cover signal, stop to move, have only A position diffuse reflection switch 4 to detect the cloth cover signal this moment, and the position of this moment is the selvedge position just.By above motion control, guarantee that whole device follows the trail of selvedge automatically, indicate at selvedge when needed.
