first, the first feeding sub-mechanism and the second feeding sub-mechanism of the feeding mechanism 10 stack the skin respectively, wherein one feeding sub-mechanism is at the feeding position, and when the skin on the feeding sub-mechanism is taken out, the driving device 12 of the feeding mechanism drives the other feeding sub-mechanism to move to the feeding position. Any feeding sub-mechanism, under the drive of the feed screw module, the feeding lifting plate 14 lifts the leather thereon, and the rhythm is as follows: the upper top of the stack of skids is removed from the feed elevator plate 14, which is raised by the height of one skid thickness.
Second, the skin adsorption module 44 of the first skin conveying mechanism 40 simultaneously adsorbs the skin on the double stations of the above-mentioned feeding sub-mechanism and conveys it to the skin positioning mechanism 30 having two positioning stations, and the skin is placed on the transparent positioning plane 31.
Thirdly, the leather adsorbing unit 53 of the left arm conveying mechanism 50 or the right arm conveying mechanism 500 descends to the positioning plane 31 and adsorbs leather, then the leather adsorbing unit 53 pauses, the image capturing device 32 captures an image of the leather, and after the image capturing is completed, the leather adsorbing unit 53 lifts the leather to separate from the positioning plane 31 and conveys the leather to the oil edge mechanism 20. Wherein, camera device can install on skin material adsorption unit 53, and at the moment of the fixed skin material of skin material adsorption unit 53 absorption, camera device acquires the image of skin material, can improve the coincidence degree of skin material profile and oily head walking route. Or, the image capturing device 32 is mounted on the top of the frame of the selvedge machine and is located right above the positioning plane 31, and captures an image of the skin when the first skin conveying mechanism 40 leaves above the positioning plane 31 and the skin adsorbing unit 53 of the left arm conveying mechanism 50 or the right arm conveying mechanism 500 comes to the above of the positioning plane 31.
Fourth, the control system processes the leather image transmitted by the image pickup device, and takes the contour of the leather as the running path of the selvedge mechanism 20.
Fifth, the control system controls the edge transverse driving device 21 and the edge longitudinal driving device 22 according to the set walking path to drive the edge head to carry out edge along the edge of the leather.
Sixth, the left arm conveyor 50 or the right arm conveyor 500 continues to longitudinally convey the oiled hide to the drying mechanism 60. The leather adsorption unit 53 of the left arm conveying mechanism or the right arm conveying mechanism transfers the adsorbed leather from the oil edge mechanism 20 to the head end of the double-layer rotary oven, the first leather clamp opening device 64 opens the leather clamps 63 and Pi Liaoga on the transmission chain 62 to clamp the leather on the leather adsorption unit, the leather adsorption unit 53 releases the leather, the transmission chain and the leather clamps on the transmission chain convey the leather into the oven cavity, and a heat source in the oven cavity heats and toasts the leather. Wherein, a first leather clip opening device 64 is matched with a transmission chain 62, and when the leather adsorption unit 53 transfers the two leather materials adsorbed to the head end of the double-layer rotary oven, the leather clips 63 on the two transmission chains are respectively opened by the corresponding first leather clip opening devices.
Seventh, when the leather clamped by the leather clamps 63 reaches the tail end of the transmission chain 62, the second cylinder 651 of the second leather clamp opening device 65 acts to drive the two push rods 652 connected with the second cylinder, and the two push rods respectively open the leather clamps on the two transmission chains. The leather clamped by the leather clamp falls to the conveying belt 67 under the action of gravity, the conveying belt conveys the leather to the head end of the oven cavity, and the head end of the transmission chain and the head end of the oven cavity are the same. The skin falls onto a receiving plate 69 below the head end of the conveyor.
Eighth, the right arm conveyor 500 is the same as the left arm conveyor 50 in the path and the completed motion, and the right arm conveyor 500 and the left arm conveyor 50 are offset, for example, when the left arm conveyor 50 is at the oil side mechanism 20, the right arm conveyor 500 is at the drying mechanism 60.
The following may be the following method for taking the contour of the above-mentioned skin as the travel path of the selvedge mechanism 20:
firstly, the camera device 32 acquires an image of the upper material positioned on the positioning plane 31 through a camera; the area of the light source below the positioning plane 31, which irradiates upwards, is larger than the area of the leather, the image capturing range of the camera device 32 is smaller than the irradiation area of the light source, the leather is placed on the positioning plane, the image obtained by the camera device is a shadow area formed by shielding the light source by the leather, and the camera device can obtain a clear leather image conveniently;
secondly, the control system identifies the outline of the leather from the image and compares the outline with the pattern stored in the control system, and if the outline pattern of the leather is stored in the memory of the control system, the control system can act on the oil edge mechanism 20 to execute an oil edge action instruction; if the contour pattern of the leather is not stored in the memory of the control system, the acquired contour pattern can be stored in the memory of the control system, then the line of the contour pattern is converted into an oil edge path execution action instruction and a storage instruction according to an instruction automatic generation program;
thirdly, the control system selects an oil edge path according to the path stored internally or the instruction newly converted in the second step;
fourth, the control system controls the selvedge mechanism 20 so that its selvedge head selvedges the edge of the skin along the selvedge path.
