The single camera fabric defect on-line detection device has compact structure and can be directly arranged on a weaving machine for on-line detection; as the single camera is adopted, the maintenance is convenient and the precision of a detection signal is good.

Description

Single camera fabric defects on-line measuring device

Technical field

The utility model relates to the quality of textile products checkout equipment, relates in particular to a kind of fabric defects on-line measuring device.

Background technology

Existing defect detection, two kinds of approach are arranged: a kind of is by human eye detection, and time-consuming, effort and loss are very high, and another kind is to have machinery to be detected as the cloth of type separately, but the expense of machine own is very high and cloth weaves, and much the fault that is produced by the factor of weaving cotton cloth can't be repaired.

For example 200820068304.1 the utility model relate to a kind of on-line testing apparatus for surface fault of grey cloth, main frame is connected by Ethernet with slave, the camera group places camera case the inside, and each camera is realized being connected by the image pick-up card that is installed in the slave the inside with slave; Slave receives host command to begin image acquisition and carries out the images acquired information processing, and to main frame transmitted image data and processing result image information, main frame is connected with fault mark machine, drives fault mark machine by host computer control image deflects are carried out the selvedge mark; Rotary encoder is installed on the same axis on the lower cloth roller by spring coupling, great power LED bar shaped array is positioned at the side of cloth rewinder roll, be connected with the fixing frame that goes up cloth rewinder roll by hinges, take one-sided forward high angle off-axis illumination, LED bar shaped array is taken axis with camera and is become the θ angle, 40 °>θ>15 ° wherein, LED bar shaped array can be around the cloth rewinder roll axle center is the swing location of θ=25 ° as angle.

But adopt a plurality of cameras in this technology, cost than higher, safeguard unsuitablely, the treatment capacity to a plurality of camera signals is very big in addition, and hardware control system is required than higher.

Summary of the invention

The single camera fabric defects on-line measuring device that the utility model provides a kind of to be convenient to safeguard, accuracy of detection is good.

A kind of single camera fabric defects on-line measuring device is made of image capturing system, image processing system and fault marking system, and described image capturing system comprises:

Guide rail along fabric width direction layout;

Can be along the reciprocating camera (being described single camera) that is used to gather the fabric face image of guide rail;

Be used to provide the light source of illumination;

And the driving-belt that is used to drive slide block movement that is connected with driving mechanism.

In the utility model fabric defects on-line measuring device when work, is along with the motion of fabric, driving-belt drives slide block and makes cam movement and gather the fabric face image, the image that collects is by the processing of image processing system, identification is also oriented fault, and the fault marking system demarcates fault at fabric face.

Described light source can adopt prior art, be used to illuminate fabric face, in order to cooperate moving of camera, also can be as preferred light source along with camera is synchronized with the movement, be the external light source driving mechanism, its type of drive can adopt prior art or the pattern motion same with camera.

When camera adopted driving-belt to drive, the two ends of guide rail were equipped with belt wheel, and having an end at least is the driving pulley that is connected with described driving mechanism, and described driving-belt is around the home on the belt wheel at guide rail two ends.

Described driving mechanism is a motor, the coaxial output shaft outside that is nested in motor of driving pulley.

Described guide rail is provided with one can be along the reciprocating slide block of guide rail, and described camera is fixed on the slide block, is convenient to the dismounting of camera.

Described light source preferably adopts flat-plate light source.

In order to realize that controlling described driving mechanism automatically inserts a motion control main frame, image processing system can be learnt the position of camera according to the signal of motion control main frame, again in conjunction with the image that collects under the current location, the textile image that the image mosaic of camera collection can be become finish just, identification is also oriented fault, all can adopt prior art about the identification and the fault mark of fault.

Control in motion control main frame, image processing system and the fault marking system and calculation process part can realize in same computer or single-chip microcomputer, also can adopt computer or chip microcontroller separately separately.

When fault was too much or excessive, image processing system also can send as required reported to the police or shutdown.The utility model fabric defects on-line measuring device, compact conformation can directly be contained in online detection on the loom, single camera also is convenient to safeguard, the detection signal precision is good owing to adopt.

Description of drawings
