Description

Technical Field

[0001] The utility model relates to the field of research and development and manufacturing of automobile parts, in particular to a fully automatic folding and unfolding tray system. Background Art

[0002] At present, there are generally two ways of folding and unfolding trays in the prior art. One is to manually control a forklift to perform the folding and unfolding tray operation. This method has low efficiency, can only complete simple folding and unfolding tray actions, cannot achieve precise positioning, and can only be applied to scenarios without automated production. The other is a semi-automatic folding and unfolding tray system. The forklift forks the tray to the positioning position, and then controls the folding and unfolding tray equipment to perform the folding and unfolding tray operation. After the operation is completed, the forklift is used for transportation again.

[0038] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] An embodiment provided by the present utility model:

[0040] Refer to Figure 1 - Figure 15 , a full-automatic folding and unfolding tray system, comprising:

[0041] The pallet disassembling machine has the outer shell 7 of the pallet disassembling machine as the main body. At the bottom end of the outer shell 7 of the pallet disassembling machine, there are two first pallet longitudinal conveying devices 5. At the rear end of the two first pallet longitudinal conveying devices 5, there is a first pallet longitudinal conveying motor 6 installed. On the top side of the first pallet longitudinal conveying device 5, there is a first pallet lifting fork 1. The first pallet lifting fork 1 is externally connected to a first transverse lifting fork motor 3. The first transverse lifting fork motor 3 is located in the middle of the interior of the outer shell 7 of the pallet disassembling machine. A first lifting mechanism gear 4 is rotatably connected to the top end of the inner wall of the outer shell 7 of the pallet disassembling machine. At the front end of the top of the inner wall of the first pallet lifting fork 1, there is a first lifting fork lifting motor 2 installed. The first lifting mechanism gear 4 is connected to the first lifting fork lifting motor 2, and the first lifting mechanism gear 4 is connected to the first pallet lifting fork 1 through a chain.

[0042] Specifically, the pallet disassembling machine sends a pallet request to the AGV in advance according to the actual pallet disassembling situation. The AGV is responsible for transporting the stacked empty pallets from the storage area to the upper pallet area of the pallet disassembling machine. After the pallet disassembling machine receives the signal that the upper pallet by the AGV is completed, it is ready to disassemble the pallets. When the pallet disassembling machine receives the disassembly instruction, it controls the disassembly mechanism to move downward. After reaching between the bottommost empty pallet and the second-layer empty pallet, the two first pallet lifting forks 1 on both sides move towards the middle, insert the first pallet lifting forks 1 between the bottommost empty pallet and the second-layer empty pallet, and then move upward a certain distance after reaching the position. At this time, the empty pallets from the second layer to the top layer have been lifted and suspended, and the bottommost empty pallet is conveyed to the automated automatic feeding mechanism through the first pallet longitudinal conveying device 5 under the pallet disassembling machine.

[0043] The pallet stacking machine has the second outer shell 21 of the pallet stacking machine as the main body. At the bottom end of the second outer shell 21 of the pallet stacking machine, there are two second pallet longitudinal conveying devices 19. At the rear end of the two second pallet longitudinal conveying devices 19, there is a second pallet longitudinal conveying motor 20 installed. On the top side of the second pallet longitudinal conveying device 19, there is a second pallet lifting fork 15. The second pallet lifting fork 15 is externally connected to a second transverse lifting fork motor 17. The second transverse lifting fork motor 17 is located in the middle of the interior of the second outer shell 21 of the pallet stacking machine. A second lifting mechanism gear 18 is rotatably connected to the top end of the inner wall of the second outer shell 21 of the pallet stacking machine. At the front end of the top of the inner wall of the second outer shell 21 of the pallet stacking machine, there is a second lifting fork lifting motor 16 installed. The second lifting mechanism gear 18 is connected to the second lifting fork lifting motor 16, and the second lifting mechanism gear 18 is connected to the second pallet lifting fork 15 through a chain.

[0044] Specifically, after the pallet with material is transported from the loading mechanism to the stacking machine, the stacking machine starts stacking. The lifting fork lifting motor 2 16 drives the pallet lifting fork 2 15 to move downward. After moving to the lowest point, the pallet lifting fork 2 15 moves to the middle. After it is in place, the pallet lifting fork 2 15 lifts the pallet with material upward and waits for the next pallet with material to reach the stacking position. The pallet lifting fork 2 15 first descends and stacks the pallet on the pallet lifting fork 2 15 onto the pallet with material that has just arrived at the stacking machine. The pallet lifting fork 2 15 is then opened. After it descends to the lowest point, the pallet lifting fork 2 15 moves to the middle. After it is in place, the pallet lifting fork 2 15 lifts the pallet with material upward. Repeat the above actions to achieve automatic stacking. After the stacking is completed, the pallet lifting fork 2 15 lifts all the pallets with material to a certain height, calls the AGV to enter the pallet transfer area of the stacking machine, and the pallet lifting fork 2 15 descends to place the pallet on the AGV, which then transfers the pallet to the warehouse area.

[0045] The automatic feeding mechanism is composed of a horizontal conveying device 8 as the main body, a horizontal conveying motor 9 is installed at the middle end of the bottom side of the horizontal conveying device 8, two pallet lifting devices 11 are arranged on the top side of the horizontal conveying device 8, a pallet lifting motor 12 is arranged at the bottom side of the pallet lifting device 11, an electric roller 10 is installed at the middle end of the top side of the pallet lifting device 11, a cam 13 is rotatably connected to the right end of the bottom side of the pallet lifting device 11, and a positioning baffle 14 is fixedly connected to the right end of the top side of the pallet lifting device 11 to prevent the pallet with materials from falling off; the automatic feeding mechanism is equipped with a robot for auxiliary feeding and grabbing;

[0046] Specifically, after the pallet dismantling machine has dismantled an empty pallet, the pallet lifting device 11 rises to prepare to receive the empty pallet. The empty pallet is transmitted to the pallet lifting device 11 at the automatic feeding mechanism through the pallet longitudinal conveying device 5 of the pallet dismantling machine. After the pallet is in place, the pallet lifting device 11 descends to allow the empty pallet to descend to the horizontal conveying device 8 of the feeding mechanism. This position is the empty pallet buffer area. The horizontal conveying device 8 moves laterally to transport the empty pallet in the buffer area to the material receiving position. After the empty pallet is in place, the robot can grab the material to the empty pallet. After completing the material receiving, the pallet lifting device 11 drives the electric roller 10 to rise, so that the pallet with material is separated from the horizontal conveying device 8 and contacts the electric roller 10. The electric roller 10 is started to drive the pallet with material to move to the pallet stacking machine, which is received by the pallet stacking machine.

[0047] Automation control system: the automation control system is equipped with electrical control cabinet, Siemens 1214PLC, Siemens KTP1200HMI, position sensors of each mechanism, AC three-phase motors of each power mechanism, frequency converter and low-voltage components;

[0048] Specifically, each system component is connected by a mechanism control cable, and the pallet disassembling machine, pallet stacking machine, and automatic feeding device are controlled. The main control process is as follows: communicate with the AGV through the Siemens 1214 PLC to call the AGV to automatically transport the empty pallet to the upper pallet mechanism of the pallet disassembling machine. Then, the pallet disassembling machine automatically disassembles the pallet according to the requirements of the automated line. For each empty pallet disassembled, the longitudinal conveying mechanism transports the empty pallet to the automatic feeding mechanism. The robot automatically grabs the sand core and places it into the empty pallet. After the placement is completed, the pallet with materials is transported to the pallet stacking machine, and the pallet stacking machine is responsible for automatic pallet stacking. When a certain number of pallets are stacked, the Siemens 1214 PLC calls the AGV to the transfer position of the pallet stacking machine to transport the pallet to the storage area.

[0049] This solution can be well compatible with the AGV automatic empty pallet replenishment solution. The production line can, according to the demand for empty pallets, make an advance reservation for the AGV to transport empty pallets to the position of the pallet disassembling machine before the empty pallets are exhausted. The pallet disassembling machine is designed with an empty pallet unloading area. After the AGV finishes unloading, the AGV exits the unloading area, and the pallet disassembling machine can directly disassemble the pallet without manual intervention, realizing the automatic call to complete the replenishment of empty containers and the automatic pallet disassembly. The pallet disassembling machine can control the lifting fork of the pallet disassembling machine to complete the pallet disassembly according to the demand of the automated line for empty pallets, realizing pallet disassembly on demand and the function of supplying empty pallets to the automated line as needed, realizing the automatic feeding of the offline products of the automated line. The automatic unloading mechanism of the pallet disassembling and stacking system is designed with a loading area. The empty pallet automatically arrives at the loading area through the conveying mechanism. The robot grabs the processed product and places it on the empty pallet, realizing the automatic loading of the empty pallet, as well as automatic pallet stacking and counting. After the empty pallet is filled with products, it reaches the pallet stacking area, and the fully automatic pallet stacking machine performs automatic pallet stacking. When the number of stacked pallets is close to the set number, call the AGV for transfer in advance.

[0050] Working principle: The pallet disassembling machine sends a pallet request to the AGV in advance according to the actual pallet disassembling situation. The AGV is responsible for transporting the stacked empty pallets from the storage area to the upper pallet area of the pallet disassembling machine. After the pallet disassembling machine receives the signal that the upper pallet by the AGV is completed, it prepares for pallet disassembling. When the pallet disassembling machine receives the pallet disassembling instruction, it controls the pallet disassembling mechanism to move downward. After reaching between the bottommost empty pallet and the second-layer empty pallet, the pallet lifting and fork-pushing device 1 on both sides moves towards the middle, inserts the pallet lifting and fork-pushing device 1 between the bottommost empty pallet and the second-layer empty pallet. After reaching the position, it moves upward a certain distance. At this time, the empty pallets from the second layer to the top layer have been lifted and suspended. The bottommost empty pallet is conveyed through the pallet longitudinal conveying device 5 below the pallet disassembling machine to the automatic feeding mechanism of the automation. After the pallet disassembling machine disassembles one empty pallet, the pallet lifting device 11 rises to prepare to receive the empty pallet. The empty pallet is conveyed to the pallet lifting device 11 at the automatic feeding mechanism through the pallet longitudinal conveying device 5 of the pallet disassembling machine. After the pallet reaches the position, the pallet lifting device 11 descends to let the empty pallet descend onto the horizontal conveying device 8 of the feeding mechanism. This position is the empty pallet buffer area. The horizontal conveying device 8 moves horizontally to convey the empty pallet in the buffer area to the material receiving position. After the empty pallet reaches the position, the robot can grab the material onto the empty pallet. After completing the material receiving, the pallet lifting device 11 drives the electric roller 10 to rise, so that the pallet with material is separated from the horizontal conveying device 8 and contacts the electric roller 10. The electric roller 10 is started to drive the pallet with material to move to the pallet stacking machine, which is received by the pallet stacking machine. After the pallet with material is conveyed from the feeding mechanism to the pallet stacking machine, the pallet stacking machine starts to stack pallets. The lifting motor 2 of the fork-lifting device drives the pallet lifting and fork-pushing device 2 to move downward. After moving to the lowest point, the pallet lifting and fork-pushing device 2 moves towards the middle. After reaching the position, the pallet lifting and fork-pushing device 2 lifts the pallet with material upward, waiting for the next pallet with material to reach the stacking position. The pallet lifting and fork-pushing device 2 first descends, stacks the pallet on the pallet lifting and fork-pushing device 2 onto the pallet with material that has just reached the pallet stacking machine, then opens the pallet lifting and fork-pushing device 2, descends to the lowest point, and the pallet lifting and fork-pushing device 2 moves towards the middle. After reaching the position, the pallet lifting and fork-pushing device 2 lifts the pallet with material upward. Repeating the above actions realizes automatic pallet stacking. After the pallet stacking is completed, the pallet lifting and fork-pushing device 2 lifts all the pallets with material to a certain height, calls the AGV to enter the pallet transfer area of the pallet stacking machine. The pallet lifting and fork-pushing device 2 descends, places the pallet on the AGV, and the AGV then transports the pallet to the storage area.
