[0002] Discs are required for the welding of scaffolding vertical poles. Several discs are welded together with round tubes. The discs need to be positioned and have the same direction. Manual selection and stacking one by one are required before they can be sent into the vertical pole welding machine for welding.

[0003] Currently, the well-known sorting and stacking of discs for scaffolding vertical poles is manual sorting and stacking, which cannot achieve fully automated welding. Summary of the Invention

[0004] Aiming at the deficiencies existing in the above technical problems, the purpose of the present invention is to provide an automatic sorting and stacking machine for scaffolding discs.

[0005] An automatic sorting and stacking machine for scaffolding discs includes a main body frame and a control box. It is characterized in that: in the middle of the upper end of the main body frame is a conveying platform. A flipping cylinder is provided on the conveying platform. A flipping support plate is fixed on the cylinder rod of the flipping cylinder. A sorting camera is provided directly above the flipping support plate. The sorting camera is electrically connected to the control box through a cable. The sorting camera takes pictures of the workpiece discs sent to the flipping support plate and transmits the pictures to the sorting system of the control box. The sorting system of the control box compares the pictures of the workpiece discs received from the sorting camera with the images taken in advance, and then sorts the workpiece discs.

[0006] A front baffle cylinder and a rear baffle cylinder for allowing or prohibiting the passage of workpiece discs are provided on both sides of the flipping cylinder; when the workpiece discs are sent to the flipping support plate by the conveying chain for sorting, the sensor receives the signal, and the front baffle cylinder resets to block the subsequent workpiece discs from moving forward; when the sorting system of the control box compares the pictures of the workpiece discs received from the sorting camera with the images taken in advance, if the comparison shows that they are the same and the front side is correct, the cylinder rod of the rear baffle cylinder drops, and the workpiece discs continue to move forward; if the comparison is different, the flipping cylinder acts to flip the workpiece discs on the flipping support plate by 180 degrees, and the flipped workpiece discs fall onto the conveying chain and continue to move forward.

[0007] Baffles are welded on both sides above the conveying platform. A groove is formed between the two baffles. An insulating backing plate is installed in the groove. Two positioning columns are fixed above the insulating backing plate. A positioning camera is provided directly above the insulating backing plate. The positioning camera and the two positioning columns are respectively electrically connected to the control box through cables. When the workpiece discs move and touch the positioning columns, the positioning columns sense the signal, and the positioning camera starts to take pictures and transmits the pictures to the positioning system of the control box, and compares them with the images taken in advance, so as to control the rotation angle of the rotating motor.

[0008] A disc feeding cylinder plate is welded to the left end of the main body frame. The disc feeding cylinder is installed at the upper end of the disc feeding cylinder plate.

The sliding plate is fixed to two parallel guide rails; by the action of the disc feeding cylinder, the sliding plate is pushed to move on the guide rail.

[0010] When gripping the workpiece disc, after the disc feeding cylinder retracts to the in-place position, the dropping cylinder drops. The gripper cylinder acts to grip the workpiece disc. The dropping cylinder resets and rises. The rotating motor starts to rotate to rotate the workpiece disc to the in-place position. The disc feeding cylinder resets and pushes forward, pushing forward to directly above the tray. The dropping cylinder drops again. The gripper cylinder releases the workpiece disc, and the workpiece disc falls onto the tray; at this time, the rotating motor resets and rotates in reverse to the origin position, and the dropping cylinder resets and rises again, waiting to grip the workpiece disc next time.

[0011] On the right side of the main body frame is a bin for holding the workpiece discs. A lifting speed reducer is installed at the bottom of the bin. Sprocket C is installed on the shaft of the lifting speed reducer. The lifting motor is connected to the lifting speed reducer. Sprocket C is connected to sprocket B fixed on transmission shaft B through chain B. Transmission shaft B is installed at the lower end of the bin; A transmission shaft A is installed at the upper left end of the bin. The conveyor belt is installed on the sprockets of transmission shaft A and transmission shaft B. A number of hanging plates are provided on the conveyor belt; The lifting motor drives the lifting speed reducer to rotate, thereby driving sprocket C to rotate. Sprocket C drives transmission shaft B to rotate through chain B, causing the conveyor belt to move from bottom to top. The workpiece discs are transported out of the bin through the hanging plates on the conveyor belt and sent to two parallel conveyor chains through the conveying plate.

[0012] The described conveying plate is inclined and welded above the baffle near transmission shaft A.

Sprocket D is connected to sprocket A installed on the shaft of the transmission speed reducer through chain A. The transmission motor is connected to the transmission speed reducer; The transmission motor drives the transmission speed reducer to rotate, thereby driving sprocket A to rotate. Sprocket A drives sprocket D to rotate through chain A, thereby driving the two parallel conveyor chains to operate, causing the conveyor chains to drive the workpiece discs to move forward.
