[0018] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , an automatic loading and unloading equipment is provided, including a material car 1, a material cage 2, a pallet, a first chain conveyor line 3, a first hoist 4, a second chain conveyor line 5, a third chain conveyor line 6, a fourth chain conveyor line 7, a first material cage positioning frame 8, a second material cage positioning frame 9, a material cage positioning cylinder 10, a second hoist 11, a push rod 12, a driving component, a material pulling hook 21, a material pulling mechanism 22, a push back mechanism 23, a frame 24, an electric control box 25, a barcode scanning gun 26, a caster 27 and a foot support 28. The material cage is arranged on the material car, and the pallet is arranged in the material cage. There are multiple pallets, and the multiple pallets are arranged in sequence from top to bottom. There are no side panels on the two opposite sides of the material cage, and side panels are arranged on the other two opposite sides. The side panels are provided with card boards, and the card boards are also arranged from top to bottom. The pallet is placed on the card board, and the upper and lower pallets do not touch each other, and there is a spacing space. The material cart is a common material cart in the prior art. An AGV trolley can be provided on the material cart. The materials to be loaded are placed on the pallet. The material cart automatically transports the material cage filled with materials to the loading position, that is, one side of the first chain conveyor line.

[0020] The first chain conveyor line, the second chain conveyor line, the third chain conveyor line and the fourth chain conveyor line have the same structure. The first chain conveyor line includes a conveyor chain 14, a transmission chain 15, a motor 16, a rotating shaft 17 and a material frame in place sensor 18. The transmission chain is wound around the motor and the rotating shaft, the conveyor chain is wound around the rotating shaft, and the material frame in place sensor is arranged on the conveyor chain. When the motor is running, the output part of the motor rotates, which can drive the transmission chain to drive, thereby driving the rotating shaft to rotate. Because the two ends of the rotating shaft extend into the conveyor chains on both sides, the conveyor chains can be driven to rotate during the rotation of the rotating shaft. The material frame in place sensor is arranged to have a positioning function.

[0021] The first elevator is arranged at the lower part of the first chain conveyor line, and the second elevator is arranged at the lower part of the third chain conveyor line. The first elevator and the second elevator are electric cylinders 19, and the electric cylinders include servo motors 20. The electric cylinders are common structures in the prior art. The first elevator can drive the first chain conveyor line to move up and down, and the second elevator can drive the third chain conveyor line to move up and down.

[0022] The fourth chain conveyor line is arranged above the second chain conveyor line, the first chain conveyor line is arranged on one side of the second chain conveyor line and the fourth chain conveyor line, and the third chain conveyor line is arranged on the other side of the second chain conveyor line and the fourth chain conveyor line. When the material vehicle arrives beside the first chain conveyor line, the first hoist lifts the first chain conveyor line to the same plane as the conveyor line of the material vehicle, and the conveyor line on the material vehicle moves simultaneously with the first chain conveyor line, so that the material cage on the material vehicle can be conveyed to the first chain conveyor line.

[0023] The first hoist drives the first chain conveyor line to move downward until it is flush with the second chain conveyor line, and at this time the first chain conveyor line, the second chain conveyor line, and the third chain conveyor line are on the same horizontal line. The three chain conveyor lines move simultaneously to transport the material cage from the first chain conveyor line, the second chain conveyor line to the third chain conveyor line in turn. When the material cage reaches the third chain conveyor line, the second hoist lifts it upward. The push rod is arranged on the fourth chain conveyor line, and the driving component is connected to the push rod. Because the conveying chains on the fourth chain conveyor line are arranged on both sides, the push rod can be arranged in the middle without affecting the conveying of the fourth chain conveyor line. The driving component is a component in the prior art that can drive the push rod to move forward and backward, and can be directly applied.

[0024] By lifting the second hoist upward, the uppermost tray in the material cage on the third chain conveyor line is flush with the push rod. The first material cage positioning frame and the second material cage positioning frame are arranged on both sides of the third chain conveyor line, and the material cage positioning cylinder is connected to the first material cage positioning frame or the second material cage positioning frame. In this embodiment, the material cage positioning cylinder is connected to the first material cage positioning frame. One side of the material cage can be arranged close to the second material cage positioning frame, and the operation of the material cage positioning cylinder can move the first material cage positioning frame to the middle, clamp and fix the material cage, and achieve the effect of positioning the material cage.

[0025] When the material cage is fixed, the push rod pushes the pallet forward, but the push rod cannot completely push the pallet out. The material pulling hook is arranged at the end of the material pulling mechanism, and the material pulling hook is connected to the material pulling mechanism through a spring, and the material pulling hook can be movably arranged on the material pulling mechanism. The material pulling mechanism includes a material pulling cylinder, which can make the material pulling hook move forward and backward. After the pallet is stable, the material pulling mechanism moves forward, and the material pulling hook moves along the side of the pallet. When it reaches the end of the pallet, under the action of the spring, the material pulling hook pops out and can hook the pallet, so that the pallet enters the material picking platform 13. The push-back mechanism is arranged between the material pulling mechanisms and is also arranged in the middle of the material picking platform. When the pallet is arranged on the material picking platform, the pallet and the push-back mechanism are in contact with each other, and the push-back mechanism is arranged at the lower part of the pallet.

[0026] The push-back mechanism includes a push-back screw 29 and a push-back motor 30, and the push-back motor is connected to the push-back screw. The operator takes out the material from the tray. After the material is taken out, the push-back screw rotates under the drive of the push-back motor, and the tray without material is transported to the material cage. During the push-back process, the material pulling hook gradually straightens under the action of the spring. When the tray is separated from the material pulling hook, the material pulling hook rebounds. The second hoist continues to rise to the height of one tray, pushes out the next tray, and repeats the cycle.

[0027] When all the materials in the cage are taken out, the third chain conveyor line is flush with the fourth chain conveyor line, and the cage flows back to the fourth chain conveyor line. When the AGV on the material vehicle recovers the cage at the upper material position, the first chain conveyor line, the third chain conveyor line and the fourth chain conveyor line are flush, and the cage flows back to the first chain conveyor line, and then flows back to the material vehicle, and the cycle is repeated in sequence.

[0028] The components of the automatic loading and unloading equipment are arranged on the frame, and the frame has an integration function. The electric control box controls the automatic loading and unloading equipment. The electric control box can be directly purchased and used on the market, and can control the components of the automatic loading and unloading equipment that need electric control. The barcode scanning gun is arranged adjacent to the third chain conveyor line and the material pulling mechanism, and has the function of scanning the material cage. The casters and the foot support are arranged at the bottom of the frame, which is a conventional setting in this field.

[0029] The beneficial effects of the present invention are:

[0030] 1. The automatic loading and unloading equipment has a simple structure, convenient loading, safe use, convenient maintenance, beautiful appearance, reasonable and safe transmission, and stable and reliable operation;

[0031] 2. The automatic loading and unloading equipment ensures that the entire equipment has high stability, reliability and safety, good compatibility, convenient adjustment and operation, the principle of balancing efficiency and safety, and strong applicability.
