Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of unstacking machine equipment, and particularly relates to an unstacking machine facilitating feeding and discharging of materials and a use method thereof. BACKGROUND

[0002] In the field of industrial production and logistics storage, the unstacking operation of bagged materials is a key link in the material processing process, and is widely applied to multiple industries such as grain, chemical industry, building materials and feedstuff. The traditional unstacking of bagged materials is mostly completed by manual operation, and the operating personnel need to carry the materials on the top of the stack one by one and place them on the designated conveying equipment. This not only has a great labor intensity, but also has a low unstacking efficiency, and it is difficult to meet the high rhythm and large batch material processing demand in modern production. In order to improve the unstacking efficiency and reduce the labor cost, semi-automatic unstacking equipment is generally used.

[0003] At present, after the traditional unstacking equipment completes the unstacking of a full set of materials, it needs to go through the step-by-step processes of returning the lifting machine, sending out the empty tray, waiting for the equipment, transferring the new full set of material tray and receiving the material by the lifting machine. When the unstacking of a full set of materials is completed, the lifting machine needs to be lowered to the low position to send out the empty tray through the conveying mechanism. This process often needs to consume a certain amount of time. After the empty tray completely leaves, the control system of the unstacking equipment will send a signal to allow the new full set of material tray to enter the unstacking equipment. In this process, the unstacking equipment is idle for a long time in the gap between the processing of the empty tray and the receiving of the new full set of tray, thereby reducing the effective working time of the unstacking equipment. SUMMARY

[0004] The present application is aimed at the above-mentioned situation, and provides an unstacking machine facilitating feeding and discharging of materials and a use method thereof, so as to solve the problem of the idle time of the unstacking equipment for a long time in the gap between the processing of the empty tray and the receiving of the new full set of tray, thereby reducing the effective working time of the unstacking equipment.

[0006] Furthermore, in this invention, two upright plates are fixed to the front of the frame, and a conveyor belt conveying mechanism is fixedly installed between the two upright plates.

[0007] Furthermore, the conveying base in this invention includes a fixed frame, and there are two fixed frames. A horizontal plate is fixed on both sides of the bottom of the two fixed frames. A first chain is provided inside the fixed frame. A first sprocket is driven to both sides of the inside of the first chain. A connecting shaft is fixedly connected between two opposing first sprockets. The outer wall of the connecting shaft is rotatably connected between the two fixed frames through a bushing. A drive motor is fixedly connected to the middle of one of the connecting shafts.

[0008] Furthermore, in this invention, a central seat is fixedly connected to one side of the drive motor. The central seat is fixed on two horizontal plates and located between two fixed frames. Several supporting rollers are installed inside the central seat. The supporting rollers overlap with the bottom of the two first chains and the material support assembly.

[0009] Furthermore, the material support assembly described in this invention includes a pallet, with two fork slots on each of the four sides of the pallet and two support slots on each of the four sides of the bottom of the pallet. The pallet is attached to the top material assembly below and is located between the two bottom baffles.

[0010] Furthermore, the top material assembly of the present invention includes a top material seat, which is installed through the through hole. The top of the top material seat is flat and overlaps with the bottom of the tray. The lower part of the protruding portion of the top material seat is sloped. A rotating shaft is fixed through the bottom of the top material seat. Deflection seats are rotated through both ends of the rotating shaft. The deflection seats are fixed to one side of the baffle. A fixing plate is fixed to one side of the top of the top material seat. The fixing plate overlaps the outside of the baffle. A spring is fixed to the other side of the fixing plate. A U-shaped frame is fixed to the end of the spring away from the fixing plate. The U-shaped frame is fixed to one side of the baffle.

[0011] Furthermore, the lifting assembly of the present invention includes a lifting motor, which is fixed at the bottom of the frame. The output end of the lifting motor is connected to a side plate. The top and bottom of the side plate are respectively rotatably connected to second sprockets through bushings. One end of the lower second sprocket is fixed to the output shaft of the lifting motor. The two second sprockets are fitted with a second chain. A movable block is fixed below one side of the second chain. The movable block is fixed to one side of the lower baffle.

[0012] Furthermore, the pushing component in this invention includes an ear plate, which is fixed to one side of the frame. A multi-stage electric push rod is fixed to the other side of the ear plate. A push block is fixed to the end of the multi-stage electric push rod. The push block is located above the upper material-lifting component and the conveyor belt conveying mechanism. The top of the conveyor belt conveying mechanism and the upper material-lifting component are on the same horizontal line.

[0013] A method for using a depalletizer that facilitates loading and unloading of materials, the method being implemented based on the aforementioned depalletizer for facilitating loading and unloading of materials, the method comprising the following steps:

[0014] S1. One end of the conveyor base is the feeding port. A forklift is manually operated to move a stack of bagged materials onto the pallet in the material support assembly. The drive motor is started to drive the two first sprockets to rotate through the connecting shaft. The first chain outside the first sprockets drives the pallet containing the materials to move to the right. During the movement of the pallet, multiple support rollers support its bottom, reducing the pressure of the pallet on the first chain, thereby improving the stability of the pallet moving the materials horizontally. After the pallet containing the materials is transferred into the frame, the drive motor stops working. At this time, the pallet is located above the four top material assemblies, and the top of the top material assemblies corresponds to the position of the support groove at the bottom of the pallet.

[0015] S2. Activate the four lifting components to make the lifting motors in the lifting components work and drive the second sprocket to rotate. The second sprocket drives the lower baffle to move upward through the second chain and the moving block. During the synchronous upward movement of the two lower baffles, multiple sets of top material components will move upward, so that the top material seat in the top material component is engaged in the tray and drives the pallet containing the material to move upward. The tray limits the top material seat to improve the stability of the pallet movement. When the material reaches the picking position, the suction cup robot is activated to depalletize the material on the pallet in sequence and transfer the material to the opening on the back of the depalletizer. The material is transported by the receiving conveyor installed at the rear of the frame. After each layer of bagged material is depalletized, the lifting components raise the height of the pallet once until all the material on the pallet is depalletized.

[0016] S3. During the upward movement of the pallet, it will contact the top material seats on the upper left and right sides of the frame. Since the bottom of the protruding part of the top material seat is designed with a slope, when the top material seat is pushed on the pallet, it will rotate around the middle of the deflection seat through the rotating shaft. At the same time, the top material seat is squeezed by the fixed plate until the top material seats on the left and right sides move out of the through hole, so as to move the pallet to the position above the top material assembly on the left and right sides. When the pallet is separated from the top material seats on both sides, the spring force supports the fixed plate, which pushes the top material seat through the through hole until the fixed plate contacts the stop bar, which plays a role in limiting the top material seat, so that the flat part of the top of the top material seat is below the pallet. After all the materials on the pallet are removed, the lifting assembly works in reverse, so that the moving block drives the empty pallet to move downward through the baffle. When the empty pallet contacts the top material seats on the left and right sides of the frame, the flat part of the top of the top material seat supports the empty pallet, so that the empty pallet will not move downward. As the moving block continues to move downward, the four top material seats below will separate from the bottom of the empty pallet.

[0017] S4. Control the extension of two multi-stage electric push rods and drive the push blocks forward, so that the two push blocks contact the two sides of the back of the empty pallet and push the empty pallet forward. Since the top material seats on both sides are on the same horizontal line as the top of the conveyor belt, the empty pallet will move onto the conveyor belt. Working in conjunction with the conveyor belt, the empty pallet will be moved out of the top material seats on both sides until the empty pallet is completely removed from the frame. Then, the multi-stage electric push rods retract and drive the push blocks to move back to the initial position. During the above process, the conveyor base will transport the newly filled pallet. Move to the lower part of the frame. As the two lower baffles move the top material components on the front and rear sides downward, the lower slope of the multiple top material seats protruding parts contacts the front and rear sides of the new pallet. The top material seats rotate around the center of the deflection seat through the rotating shaft and disengage from the through hole until the top material seats are located below the new pallet. With the help of the spring force supporting the fixing plate, the fixing plate drives the top material seats through the through hole, so that the flat part of the top of the top material seats is below the pallet. Control the lifting component to lift the new pallet upward, and cooperate with the suction cup robot to destacking the materials.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention involves lifting a pallet upwards. During the upward movement, the pallet contacts the top material seats on the upper left and right sides of the frame. After moving the pallet above the top material components on the left and right sides, the spring force supports the fixing plate, ensuring that the flat part of the top material seat is below the two pallets. After removing all material from the pallet, the lifting component reverses its operation, causing the moving block to move the empty pallet downwards via the baffle. When the empty pallet contacts the top material seats on the left and right sides of the frame, the flat part of the top material seat supports the empty pallet, preventing it from moving downwards. As the moving block continues to move downwards, the four top material seats below detach from the bottom of the empty pallet. This controls the extension of two multi-stage electric push rods, which in turn move the push block forward, simultaneously pushing the empty pallet. Empty pallets move to the conveyor belt, working in conjunction with it to move them out of the top material seats on both sides of the frame until they are completely removed. The conveyor base then moves the newly filled pallet to the lower part of the frame. Since the flat part of the top material seat is located below the two pallets, the lifting component is controlled again to lift the new pallet upwards. In conjunction with the suction cup robot, the material is destacking. Therefore, after destacking, the empty pallet can be automatically recovered. There is no need to transfer the empty pallet to the conveyor base and then send it away before connecting it to the new pallet. This seamless process of empty pallet delivery and new pallet reception greatly reduces the idle time between empty pallet processing and new pallet reception, ensuring the effective working time of the destacking equipment.

[0020] 2. In this invention, when a pallet is transferred via a conveyor base, multiple support rollers support its bottom, reducing the pressure of the pallet on the first chain and thus improving the stability of the pallet in moving materials horizontally. During the lifting process, two lower baffles move the top material components on the front and rear sides downward, causing the lower slopes of the protruding parts of multiple top material seats to contact the front and rear sides of the new pallet. The top material seats rotate around the center of the deflection seat via a rotating shaft. The top material seats compress the springs through the fixed plate until the top material seats move out of the through hole. When the pallet detaches from the top material seats on both sides, the spring force supports the fixed plate, causing the fixed plate to push the top material seats through the through hole until the fixed plate contacts the stop bar, thus limiting the position of the top material seats. This ensures that the flat part of the top of the top material seats is located below the pallet, and the baffles move the top material seats upward, allowing the top material seats to lift the pallet. Therefore, it is not necessary to remove the pallet, move the top material seats downward, and then return the pallet to its original position to complete the pallet adjustment work, improving work efficiency and ease of operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0033] See Figures 1-9 This invention is a destacking machine for easy loading and unloading of materials, comprising a frame 1, a suction cup manipulator 2 mounted on the top of the frame 1, a conveying base 3 fixedly mounted on the bottom of the frame 1, a material support assembly 4 overlapping the middle of the conveying base 3, baffles 5 respectively provided on the front and rear sides of the material support assembly 4 and on the upper sides of the frame 1, a stop bar 6 fixedly connected to the side of the baffle 5 away from the material support assembly 4, support frames 7 fixedly connected to the two upper baffles 5 respectively, the support frames 7 fixed to the top of the inner wall of the frame 1, two through holes 8 opened in the baffles 5, a top material assembly 9 installed through the through holes 8, the two lower top material assemblies 9 overlapping the bottom of the material support assembly 4, lifting assemblies 10 fixedly mounted at the four corners of the inner wall of the frame 1, the two lifting assemblies 10 on the same side fixed to the two sides of the lower baffle 5, and two pushing assemblies 11 respectively provided on one side of the two upper baffles 5, the two pushing assemblies 11 fixedly connected to the two sides inside the frame 1 respectively.

[0034] As a further embodiment of the present invention, the conveying base 3 includes a fixed frame 301, and there are two fixed frames 301. A horizontal plate 302 is fixed on both sides of the bottom of the two fixed frames 301 respectively. A first chain 303 is provided inside the fixed frame 301. A first sprocket 304 is drivenly connected to both sides inside the first chain 303 respectively. A connecting shaft 305 is fixedly connected between the two opposing first sprockets 304. The outer wall of the connecting shaft 305 is rotatably connected between the two fixed frames 301 through a bushing. A drive motor 306 is fixedly connected to the middle of one of the connecting shafts 305.

[0035] During operation, the drive motor 306 is started, which drives the two first sprockets 304 to rotate through the connecting shaft 305. This causes the first chain 303 outside the first sprockets 304 to move the pallet 401 containing the material to the right, making it easier to transfer the pallet 401.

[0036] As a further embodiment of the present invention, a central seat 307 is fixedly connected to one side of the drive motor 306. The central seat 307 is fixed on two horizontal plates 302 and located between two fixed frames 301. A plurality of supporting rollers 308 are installed inside the central seat 307. The supporting rollers 308 overlap with the bottom of the two first chains 303 and the material support assembly 4.

[0037] During operation, the bottom of the pallet 401 is supported by multiple support rollers 308 as it moves, reducing the pressure exerted by the pallet 401 on the first chain 303, thereby improving the stability of the pallet 401 in moving materials horizontally.

[0038] As a further embodiment of the present invention, the material support assembly 4 includes a tray 401, two fork slots 402 are respectively opened around the perimeter of the tray 401, two support slots 403 are respectively opened around the bottom perimeter of the tray 401, the tray 401 overlaps the material support assembly 9 below, and the tray 401 is located between the two baffles 5 below.

[0039] During operation, the top of the top material assembly 9 corresponds to the position of the groove 403 at the bottom of the pallet 401. As the top of the top material assembly 9 is inserted into the groove 403 and moves the pallet 401 containing the material upward, the groove 403 limits the top material seat 901, thereby improving the stability of the movement of the pallet 401.

[0040] As a further embodiment of the present invention, the top material assembly 9 includes a top material seat 901, which is installed through the through hole 8. The top of the top material seat 901 is flat and overlaps with the bottom of the tray 401. The lower part of the protruding portion of the top material seat 901 is sloped. A rotating shaft 903 is fixed through the bottom end of the top material seat 901. A deflection seat 902 is rotatably connected to both ends of the rotating shaft 903. The deflection seat 902 is fixed to one side of the baffle 5. A fixing plate 904 is fixed to one side of the top of the top material seat 901. The fixing plate 904 overlaps the outside of the baffle 6. A spring 905 is fixed to the other side of the fixing plate 904. A U-shaped frame 906 is fixed to the end of the spring 905 away from the fixing plate 904. The U-shaped frame 906 is fixed to one side of the baffle 5.

[0041] During operation, because the protruding part of the top material seat 901 has a sloping design below, when the top material seat 901 is pushed on the tray 401, it will rotate around the middle of the deflection seat 902 through the rotating shaft 903. At the same time, the top material seat 901 compresses the spring 905 through the fixing plate 904 until the top material seats 901 on the left and right sides move out of the through hole 8, so as to move the tray 401 to the position above the top material assembly 9 on the left and right sides.

[0042] When the pallet 401 detaches from the top supports 901 on both sides, the spring force of the spring 905 supports the fixing plate 904, causing the fixing plate 904 to push the top support 901 through the through hole 8 until the fixing plate 904 contacts the stop bar 6, which limits the top support 901 and keeps the flat part of the top of the top support 901 below the pallet 401. The flat part of the top of the top of the top support 901 supports the empty pallet 401 and prevents the empty pallet from moving down.

[0043] As a further embodiment of the present invention, the lifting assembly 10 includes a lifting motor 101, which is fixed at the bottom of the frame 1. The output end of the lifting motor 101 is connected to a side plate 105. The top and bottom of the side plate 105 are respectively rotatably connected to a second sprocket 102 through a bushing. One end of the lower second sprocket 102 is fixed to the output shaft of the lifting motor 101. The two second sprockets 102 are sleeved with a second chain 103. A moving block 104 is fixed below one side of the second chain 103. The moving block 104 is fixed to one side of the lower baffle 5.

[0044] During operation, the lifting motor 101 operates and drives the second sprocket 102 to rotate. The second sprocket 102 then drives the lower baffle 5 to move upward through the second chain 103 and the moving block 104. As the two lower baffles 5 move upward synchronously, they will drive multiple sets of top material components 9 to move upward, thereby improving the stability of the vertical position adjustment of the pallet 401.

[0045] As a further embodiment of the present invention, the pushing assembly 11 includes an ear plate 111, which is fixed to one side of the frame 1. A multi-stage electric push rod 112 is fixed to the other side of the ear plate 111. A push block 113 is fixed to the end of the multi-stage electric push rod 112. The push block 113 is located above the upper material lifting assembly 9 and the conveyor belt conveying mechanism 12. The top of the conveyor belt conveying mechanism 12 and the top of the upper material lifting assembly 9 are on the same horizontal line. Two upright plates 13 are fixed to the front of the frame 1, and the conveyor belt conveying mechanism 12 is fixedly installed between the two upright plates 13.

[0046] During operation, the two multi-stage electric push rods 112 are extended and drive the push blocks 113 to move forward, so that the two push blocks 113 contact the two sides of the back of the empty pallet 401 respectively and push the empty pallet 401 forward. The empty pallet 401 will move to the conveyor belt conveyor mechanism 12 and work with the conveyor belt conveyor mechanism 12 to move the empty pallet 401 out of the top material seats 901 on both sides above, so that the empty pallet 401 can be completely removed from the frame 1, and the purpose of automatically recycling the empty pallet 401 is achieved.

[0047] The present invention also provides a method for using a destacking machine that facilitates loading and unloading of materials, the method comprising the following steps:

[0048] S1. One end of the conveying base 3 is a feeding port. A forklift is manually operated to move a stack of bagged materials onto the pallet 401 in the material support assembly 4. The drive motor 306 is started to drive the two first sprockets 304 to rotate through the connecting shaft 305. The first chain 303 outside the first sprockets 304 drives the pallet 401 containing the materials to move to the right. During the movement of the pallet 401, the bottom of it is supported by multiple support rollers 308 to reduce the pressure of the pallet 401 on the first chain 303, thereby improving the stability of the pallet 401 in moving the materials horizontally. After the pallet 401 containing the materials is transferred into the frame 1, the drive motor 306 is stopped. At this time, the pallet 401 is located above the four top material assemblies 9, and the top of the top material assembly 9 corresponds to the position of the support groove 403 at the bottom of the pallet 401.

[0049] S2. Start the four lifting components 10, so that the lifting motor 101 in the lifting component 10 works and drives the second sprocket 102 to rotate. The second sprocket 102 drives the lower baffle 5 to move upward through the second chain 103 and the moving block 104. During the synchronous upward movement of the two lower baffles 5, multiple sets of top material components 9 will move upward, so that the top material seat 901 in the top material component 9 is inserted into the tray 403 and drives the pallet 401 containing the material to move upward. The tray 403 limits the top material seat 901, improves the stability of the pallet 401 movement, and brings the material to the picking position. Start the suction cup robot 2 to unpile the material on the pallet 401 in sequence and transfer the material to the opening on the back of the depalletizer. The material is transported by the receiving conveyor installed at the rear of the frame 1. After each layer of bagged material is unpacked, the lifting component 10 raises the height of the pallet 401 once until all the material on the pallet 401 is unpacked.

[0050] S3. During the upward movement of the pallet 401, it will contact the top material seats 901 on the upper left and right sides inside the frame 1. Since the lower part of the protruding part of the top material seat 901 is designed with a slope, when the top material seat 901 is pushed on the pallet 401, it will rotate around the middle of the deflection seat 902 through the rotating shaft 903. At the same time, the top material seat 901 is compressed by the spring 905 through the fixing plate 904 until the top material seats 901 on the left and right sides move out of the through hole 8, so as to move the pallet 401 to the position above the top material assembly 9 on the left and right sides. When the pallet 401 is separated from the top material seats 901 on both sides, the elastic force of the spring 905 supports the fixing plate 904, so that the fixing plate 904... 04 Push the top material seat 901 through the through hole 8 until the fixed plate 904 contacts the stop bar 6, which plays a role in limiting the top material seat 901, so that the flat part of the top of the top material seat 901 is located below the tray 401. After all the materials on the tray are removed, the lifting component 10 works in reverse, so that the moving block 104 drives the empty tray 401 to move downward through the baffle 5. When the empty tray 401 contacts the top material seats 901 on the left and right sides of the frame 1, the flat part of the top of the top material seat 901 supports the empty tray 401, so that the empty tray will not move down. As the moving block 104 continues to move down, the four top material seats 901 below will detach from the bottom of the empty tray 401.

[0051] S4. Control the extension of two multi-stage electric push rods 112 and drive the push block 113 to move forward, so that the two push blocks 113 contact the two sides of the back of the empty pallet 401 respectively and push the empty pallet 401 forward. Since the top material seats 901 on the upper two sides are on the same horizontal line as the top of the conveyor belt conveying mechanism 12, the empty pallet 401 will move onto the conveyor belt conveying mechanism 12 and work with the conveyor belt conveying mechanism 12 to move the empty pallet 401 out of the top material seats 901 on the upper two sides until the empty pallet 401 is completely removed from the frame 1. Then, the multi-stage electric push rods 112 retract and drive the push block 113 to move to the initial position.

[0052] During the above process, the conveying base 3 moves the newly filled pallet 401 to the lower part of the frame 1. As the two lower baffles 5 drive the top material components 9 on the front and rear sides to move down, the lower slope of the protruding parts of multiple top material seats 901 contacts the front and rear sides of the new pallet 401. The top material seats 901 rotate around the middle of the deflection seat 902 through the rotating shaft 903 and disengage from the through hole 8 until the top material seats 901 are located below the new pallet 401. With the help of the elastic force of the spring 905, the fixing plate 904 is supported, so that the fixing plate 904 drives the top material seats 901 to pass through the through hole 8, so that the flat part of the top of the top material seats 901 is located below the pallet 401. The lifting component 10 is controlled to work again to lift the new pallet 401 upward, and the suction cup robot 2 is used to destacking the materials.

[0053] The above steps enable efficient and rapid destacking operations.

9. A method of using a depalletizer that facilitates loading and unloading of materials, the method being implemented based on the depalletizer for facilitating loading and unloading of materials as described in any one of claims 1 to 8, characterized in that: The usage method includes the following steps: S1. One end of the conveyor base is the feeding port. A forklift is manually operated to move a stack of bagged materials onto the pallet in the material support assembly. The drive motor is started to drive the two first sprockets to rotate through the connecting shaft. The first chain outside the first sprockets drives the pallet containing the materials to move to the right. During the movement of the pallet, multiple support rollers support its bottom, reducing the pressure of the pallet on the first chain, thereby improving the stability of the pallet moving the materials horizontally. After the pallet containing the materials is transferred into the frame, the drive motor stops working. At this time, the pallet is located above the four top material assemblies, and the top of the top material assemblies corresponds to the position of the support groove at the bottom of the pallet. S2. Activate the four lifting components to make the lifting motors in the lifting components work and drive the second sprocket to rotate. The second sprocket drives the lower baffle to move upward through the second chain and the moving block. During the synchronous upward movement of the two lower baffles, multiple sets of top material components will move upward, so that the top material seat in the top material component is engaged in the tray and drives the pallet containing the material to move upward. The tray limits the top material seat to improve the stability of the pallet movement. When the material reaches the picking position, the suction cup robot is activated to depalletize the material on the pallet in sequence and transfer the material to the opening on the back of the depalletizer. The material is transported by the receiving conveyor installed at the rear of the frame. After each layer of bagged material is depalletized, the lifting components raise the height of the pallet once until all the material on the pallet is depalletized. S3. During the upward movement of the pallet, it will contact the top material seats on the upper left and right sides of the frame. Since the bottom of the protruding part of the top material seat is designed with a slope, when the top material seat is pushed on the pallet, it will rotate around the middle of the deflection seat through the rotating shaft. At the same time, the top material seat is squeezed by the fixed plate until the top material seats on the left and right sides move out of the through hole, so as to move the pallet to the position above the top material assembly on the left and right sides. When the pallet is separated from the top material seats on both sides, the spring force supports the fixed plate, which pushes the top material seat through the through hole until the fixed plate contacts the stop bar, which plays a role in limiting the top material seat, so that the flat part of the top of the top material seat is below the pallet. After all the materials on the pallet are removed, the lifting assembly works in reverse, so that the moving block drives the empty pallet to move downward through the baffle. When the empty pallet contacts the top material seats on the left and right sides of the frame, the flat part of the top of the top material seat supports the empty pallet, so that the empty pallet will not move downward. As the moving block continues to move downward, the four top material seats below will separate from the bottom of the empty pallet. S4. Control the extension of two multi-stage electric push rods and drive the push blocks forward, so that the two push blocks contact the two sides of the back of the empty pallet and push the empty pallet forward. Since the top material seats on both sides are on the same horizontal line as the top of the conveyor belt, the empty pallet will move onto the conveyor belt. Working in conjunction with the conveyor belt, the empty pallet will be moved out of the top material seats on both sides until the empty pallet is completely removed from the frame. Then, the multi-stage electric push rods retract and drive the push blocks to move back to the initial position. During the above process, the conveyor base will transport the newly filled pallet. Move to the lower part of the frame. As the two lower baffles move the top material components on the front and rear sides downward, the lower slope of the multiple top material seats protruding parts contacts the front and rear sides of the new pallet. The top material seats rotate around the center of the deflection seat through the rotating shaft and disengage from the through hole until the top material seats are located below the new pallet. With the help of the spring force supporting the fixing plate, the fixing plate drives the top material seats through the through hole, so that the flat part of the top of the top material seats is below the pallet. Control the lifting component to lift the new pallet upward, and cooperate with the suction cup robot to destacking the materials.
