[0002] At present, industrial sites often only use a single sensor to determine whether there is material or not, and do not judge whether there is material on the conveying equipment, the number of incoming materials, the color of the material, and whether it is metal or non-metal.

[0003] Therefore, in the case of mixed materials, traditional technology cannot accurately judge what kind of materials the incoming materials are, and it is difficult to avoid the problem of multiple materials and wrong incoming materials when assembling the equipment. Manual screening increases the labor cost of the enterprise and cannot effectively reduce the probability of wrong incoming materials in the enterprise production line. How to ensure that only one material falls at a time in the mixed state to avoid multiple materials and wrong incoming materials has practical application significance. Summary of the invention

[0037] Among them, the material transport component 1 is arranged at the upper ends of the first support column 2 and the second support column 3, and the storage bin 4 is connected to the feed end of the material transport component 1; the storage bin 4 is formed with a discharge port 12 at a position close to the material transport component 1; the sensor mounting frame 5 is fixed to the side of the material transport component 1, and the sensor mounting frame 5 is connected with an inductive sensor 7 and a photoelectric sensor 6, and the inductive sensor 7 is used to detect the metal properties of the material on the material transport component 1; the photoelectric sensor 6 is used to detect the color of the material on the material transport component 1;

[0039] Among them, the material transport component 1, the photoelectric sensor 6, the inductive sensor 7, the first cylinder 9, the second cylinder 10, and the material gripping component 11 are all electrically connected to the programmable controller.

[0040] In this embodiment, the material transport assembly 1 includes a first mounting seat 13, a second mounting seat 14, a material conveyor belt 15 and a conveying drive motor 16; the first mounting seat 13 is fixed to the upper end of the first support column 2, the second mounting seat 14 is fixed to the upper end of the second support column 3, the material conveyor belt 15 runs between the first mounting seat 13 and the second mounting seat 14, and the driving end of the material conveyor belt 15 is connected to the conveying drive motor 16.

[0041] Specifically, the material transport component 1 is installed above the first support column 2 and the second support column 3 through the first mounting seat 13 and the second mounting seat 14. At the same time, the material conveyor belt 15 runs between the first mounting seat 13 and the second mounting seat 14 through the driving shaft and the driven shaft configured at both ends. The driving shaft of the material conveyor belt 15 is driven by the conveying drive motor 16, thereby realizing the material conveying function of the material conveyor belt 15. The material transport component 1 itself can adopt a material conveyor. Among them, the conveying drive motor 16 adopts a stepper motor, which has low noise, small size, low energy consumption, high power utilization rate, and low maintenance cost.

[0042] In this embodiment, a material delivery arrival detection optical fiber 17 is provided on the upper portion of the first mounting seat 13. The detection optical fiber 17 is electrically connected to a programmable controller, and the programmable controller controls the action of the conveying drive motor 16 according to the material arrival signal detected by the detection optical fiber 17.

The color of the non-metallic material can be sensed by the photoelectric sensor 6.

[0044] In this embodiment, the material clamping assembly 11 includes a lifting drive cylinder 18, a rotating drive cylinder 19, a material clamping cylinder 20 and a material clamping claw 21; the driving end of the lifting drive cylinder 18 is connected to the rotating drive cylinder 19, the driving end of the rotating drive cylinder 19 is connected to the material clamping cylinder 20, and the driving end of the material clamping cylinder 20 is connected to the material clamping claw 21.

[0046] In this embodiment, the head of the first cylinder 9 is connected to the first plate 22, and the first plate 22 extends into the interior of the storage bin 4; the second cylinder 10 is located below the first cylinder 9, and the head of the second cylinder 10 is connected to the second plate 23, and the second plate 23 extends into the interior of the storage bin 4; in the initial state, the material transportation component 1 is in a stopped state, the first plate 22 connected to the first cylinder 9 is in a retracted state, and the second plate 23 connected to the second cylinder 10 is in an extended state, and the material to be discharged from the storage bin 4 is on the second plate 23; when the material transportation component 1 starts to run: the first plate 22 changes from a retracted state to an extended state to block the material inside the storage bin 4; the second plate 23 changes from an extended state to a retracted state, so that the material to be discharged on the second plate 23 falls down and is output from the discharge port 12 to the material transportation component 1.

[0047] Among them, when the material on the material transport component 1 passes through the inductive sensor 7 and the photoelectric sensor 6, if the material on the material transport component 1 is a metal material, the inductive sensor 7 sends a signal to the programmable controller to return the first cylinder 9 and the second cylinder 10 to the initial state; when the material on the material transport component 1 touches the contact of the detection optical fiber 17, the programmable controller controls the material transport component 1 to stop running, and triggers the material clamping component 11 to clamp and transfer the material on the material transport component 1; after the material on the material transport component 1 is clamped and transferred, the material transport component 1 enters the running state from the stopped state.

[0048] Among them, if the material on the material transport component 1 is a non-metallic material, the photoelectric sensor 6 sends a signal to the programmable controller to return the first cylinder 9 and the second cylinder 10 to the initial state; if the non-metallic material on the material transport component 1 is white, the programmable controller detects that the white contact is connected, and resets the first cylinder 9 and the second cylinder 10 at the same time; if the non-metallic material on the material transport component 1 is black, the programmable controller detects that the black contact is connected, and resets the first cylinder 9 and the second cylinder 10 at the same time.

[0049] The operating principle of the present invention is as follows:

[0050] In the initial state: there is material in the storage bin 4, the programmable controller is powered on and there is no alarm, the magnetic switch on the first cylinder 9 detects that the first cylinder 9 is in a retracted state, the second cylinder 10 is in an extended state, and the step-type material transport component 1 is in a stopped state.

[0051] When the start button of the material transport component 1 is pressed, the first cylinder 9 changes from retracting to extending, and the second cylinder 10 changes from extending to retracting. After the two cylinders have completed the operation, the programmable controller delays 0.5S to trigger the material transport component 1 to run with the material. When the material passes through the inductive sensor 7 and the photoelectric sensor 6, if it is a metal material, only the inductive sensor 7 will send a signal to the programmable controller. The programmable controller detects that the metal contact is connected and resets the two pen-shaped cylinders at the same time, that is, the first cylinder 9 changes to retracting and the second cylinder 10 changes to extending. The set numbers are saved through the MOVE instruction inside the programmable logic controller, and the number is counted as 1. The material transport component 1 continues to move forward with the material until the material touches the amplifier contact of the detection optical fiber 17 at the end. The material transport component 1 stops running, and then triggers the material clamping component 11 to clamp the material. After the material is clamped and leaves, the equipment operation condition is triggered again;

[0052] Next, the first cylinder 9 changes from retracting to extending, and the second cylinder 10 changes from extending to retracting. After the two cylinders have completed the operation, the programmable controller delays for 0.5S and then triggers the material transport component 1 to carry the material to run. When the material passes through the inductive sensor 7 and the photoelectric sensor 6, if it is a white material, only the photoelectric sensor 6 will send a signal to the programmable controller. The programmable controller detects that the white contact is connected and resets the two pen-shaped cylinders at the same time, that is, the first cylinder 9 becomes retracted and the second cylinder 10 becomes extended. The set number is saved through the MOVE instruction inside the programmable logic controller, and the number is counted as 1. The material transport component 1 continues to move forward with the material until the material touches the amplifier contact of the detection optical fiber 17 at the end. The material transport component 1 stops running, and then triggers the material clamping component 11 to clamp the material. After the material is clamped and leaves, the equipment operation condition is triggered again;

[0053] Next, the first cylinder 9 changes from retracting to extending, and the second cylinder 10 changes from extending to retracting. After the two cylinders have completed the operation, the programmable controller delays for 0.5S and then triggers the material transport component 1 to carry the material. When the material passes through the inductive sensor 7 and the photoelectric sensor 6, if it is a black material, neither the inductive sensor 7 nor the photoelectric sensor 6 sends a signal to the programmable controller. The programmable controller detects that the black contact is connected and resets the two pen-shaped cylinders at the same time, that is, the first cylinder 9 changes to retracting and the second cylinder 10 changes to extending. The set numbers are saved through the MOVE instruction inside the programmable logic controller, and the number is counted as 1. The material transport component 1 continues to move forward with the material until the material touches the amplifier contact of the detection optical fiber 17 at the end. The material transport component 1 stops running, and then triggers the material clamping component 11 to clamp the material. After the material is clamped and leaves, the equipment operation conditions are triggered again.
