The detection slider of the detection linear module 6 is positioned on one side of the detection linear module 6 close to the discharge end of the detection conveyor belt 1, when the positioning sensor 7 detects the edge leather material, a signal is sent to the controller 28, the controller 28 sends a stop signal to the motor of the detection conveyor belt 1, and the detection conveyor belt 1 stops moving.
The controller 28 sends detection signals to the silicon material detection device 2, the probe 2-1 of the silicon material detection device 2 moves downwards to detect the resistivity and the P/N type of one end of the side leather material, detection data are transmitted to the controller 28, after the detection of one end of the side leather material is finished, the probe 2-1 rises to restore to the original position, the detection slide block of the detection linear module 6 moves towards the feeding direction of the detection conveyor belt 1, the silicon material detection device 2 moves along with the detection slide block, after the positioning sensor 7 determines the position of the other end of the side leather material, signals are sent to the controller 28, the controller 28 sends stop signals to the motor of the detection linear module 6, the detection slide block stops moving, the controller 28 sends detection signals to the silicon material detection device 2 again, the probe 2-1 descends to start to detect the resistivity and the P/N type of the other end of the side leather material, and the detection data are transmitted to the controller 28.
After the detection is finished, the detection sliding block of the detection linear module 6 automatically restores to one side of the detection linear module 6 close to the discharge end of the detection conveyer belt 1, the controller 28 sends starting signals to the motors of the detection conveyer belt 1 and the shunt conveyer belt 3, the detection conveyer belt 1 and the shunt conveyer belt 3 are started, the side leather materials are conveyed to the shunt conveyer belt 3, the shunt feeding sensor 9 detects that the side leather materials are completely arranged on the shunt conveyer belt 3, then the controller 28 sends signals to the controller 28, and the controller 28 sends stop signals to the shunt conveyer belt 3; the controller 28 divides the side materials into different grades according to the detection value of the side materials, and then sends corresponding signals to the motor of the diversion linear module 8 and the diversion conveyor belt 3 according to the grade to which the side materials belong.
2. Sorting:
When the edge leather is detected as a defective product, the sliding block of the diversion linear module 8 moves leftwards, so that the diversion conveyor belt 3 is in butt joint with the waste stack conveyor belt 20-3 of the waste stack basket 20, the conveying direction of the diversion conveyor belt 3 faces the waste stack basket 20, meanwhile, the controller 28 sends a starting signal to the motor of the waste stack conveyor belt 20-3, after the motor runs for a certain number of turns, the waste stack conveyor belt 20-3 places the defective product on the waste horizontal supporting plate 20-5, the motor of the waste lifting linear module 20-4 is linked with the motor of the waste stack conveyor belt 20-3, the motor of the waste lifting linear module 20-4 is started after the motor of the waste stack conveyor belt 20-3 stops moving, the waste lifting linear module 20-4 drives the waste lifting basket 20-2 to move upwards, the next layer of the waste horizontal supporting plate 20-5 is lifted to be aligned with the waste stack conveyor belt 20-3, the controller 28 sends a signal to the diversion conveyor belt 3, and the diversion conveyor belt 3 resumes the recovery position to be in butt joint with the detection conveyor belt 1; when the bottommost layer of the waste lifting basket 20-2 is aligned with the waste stacking conveyor belt 20-3, the waste full-load sensor 20-7 sends an alarm signal to the waste audible and visual alarm device 20-6, the waste audible and visual alarm device 20-6 starts to alarm, and after receiving the alarm, staff takes out the edge leather materials in the waste lifting basket 20-2 and uniformly places the edge leather materials in a waste storage area, so that the full-load edge leather materials are prevented from being scattered on the ground.
When the edge leather is detected as a first grade product, the diversion linear module 8 does not move, the conveying direction of the diversion conveying belt 3 faces towards the cleaning unit, the controller 28 sends a starting signal to the motor of the diversion conveying belt 3, and the diversion conveying belt 3 conveys the edge leather into the cleaning unit; when the edge leather material is detected as a secondary product or a tertiary product, the diversion linear module 8 moves leftwards or rightwards respectively, the secondary product enters the left side of the cleaning unit, and the tertiary product enters the right side of the cleaning unit.
3. Cleaning:
The cleaning unit is divided into three cleaning lines, so that the edge leather materials with different grades can be cleaned simultaneously, and the cleaning time is shortened; after the edge leather enters different cleaning lines of the cleaning unit according to the grade, the feeding sensor 19 at the feeding end of the corresponding cleaning line detects that the edge leather enters, and the feeding sensor 19 sends an opening signal to the spray valve 13 of the cleaning liquid pipe 11 and the water washing pipe 12 corresponding to the feeding sensor 19, so that the spray valve 13 is opened when the edge leather exists in each cleaning line, and the spray valve 13 is closed when the edge leather does not exist, thereby saving cleaning liquid and water resources; the edge leather passes through the lower part of the cleaning liquid pipe 11, is sprayed with cleaning liquid, is conveyed by the roller conveyor 10 to move towards the cleaning liquid brush roller set 15, and is brushed by the cleaning liquid brush roller set 15; the brushed edge leather continuously moves to the discharging end of the roller conveyor 10, and the water washing pipe 12 sprays water to wash the edge leather when the edge leather is washed by primary water washing, brushing and secondary water washing in sequence, and the washing water is running water, so that the edge leather is washed cleanly and thoroughly, the impurity in the washing water is prevented from polluting the edge leather again, and the cleanliness of the edge leather is ensured;
the sewage after cleaning and primary washing falls into the sewage tank 17 for sewage disposal, and the water after secondary washing falls into the circulating water tank 18, so that a large amount of water resources can be saved because the water after secondary washing is cleaner and the primary washing pipe 12 for primary washing is used for primary washing of the edge leather through the circulating pipeline;
the cleaned primary product is conveyed to a discharging conveyor belt 4, the cleaned secondary product enters a classification material stack basket 21 of the secondary product, and the cleaned tertiary product enters the classification material stack basket 21 of the tertiary product; the classification stack basket 21 works on the same principle as the reject stack basket 20.
