[0001] The invention relates to the technical field of palletizing, and in particular to a palletizing device and method for producing and processing prefabricated panels. Background Art

[0002] Precast panels are concrete products that are produced in factories through standardized, mechanized processing. In the actual production process of precast panels, concrete precast panels will be continuously produced by production equipment. After they are formed and demoulded, they need to be sent to the stacking equipment through a conveyor, and then the clamping mechanism in the stacking equipment will stack the precast panels one by one on the fork plate;

[0003] In the prior art, patent CN116605663A includes a feed conveyor and a conveyor track frame, a layer-by-layer placement device for receiving prefabricated panels one by one and placing them up and down layer by layer is movably arranged between the feed conveyor and the conveyor track frame, a material grabbing and stacking device is arranged on the conveyor track frame, a driving device for realizing the movement of the material grabbing and stacking device along the guide track on the conveyor track frame is arranged on the conveyor track frame, and a fork plate seat is arranged directly below the conveyor track frame away from the side of the layer-by-layer placement device; the prefabricated panel conveying and stacking equipment disclosed in the present invention can clamp and convey multiple prefabricated panels at one time, and then unload and stack them. Compared with the prior art, the whole equipment has a higher efficiency in conveying and stacking prefabricated panels, and at the same time, it also effectively realizes the automatic layered placement effect when multiple prefabricated panels are unloaded and stacked synchronously;

[0004] However, the existing stacking device requires manual placement of wooden strips between the prefabricated boards to separate the prefabricated boards, resulting in gaps between the two groups of prefabricated boards. Manual placement of wooden strips results in inaccurate positioning and insufficient support for the prefabricated boards, which can cause the prefabricated boards to tilt and become unstable after being stacked.

[0013] Preferably, a supporting plate is fixed on the surface of the L-shaped rod, and the supporting plate moves with the L-shaped rod, and the supporting plate is supported on the surface of the supporting plate, and the supporting plate is no longer supported on the surface of the supporting plate after the L-shaped rod moves. An adjusting groove is provided on the surface of the supporting plate, and the force-bearing rod is located in the adjusting groove, and the force-bearing rod can move in the adjusting groove. The cross-section of the force-bearing rod is T-shaped, and the cross-section of the adjusting groove is also T-shaped. A second spring is arranged in the adjusting groove, one end of the second spring is connected to the inner wall of the adjusting groove, and the other end is connected to the surface of the force-bearing rod, and the second spring has a thrust on the force-bearing rod.

[0014] Preferably, the rollers are provided in multiple groups, the multiple groups of rollers are distributed on the surface of the support plate, and the rollers can roll on the surface of the support plate.

[0015] Preferably, the prefabricated panels move along with the conveyor belt, and fall to the top of the support panels after movement. The distance between the two groups of support panels is smaller than the width of the prefabricated panels, and the support wood on the surface of the second support panel is pushed and moved to the surface of the support panel. The support wood is located at the bottom of the prefabricated panels, and the width of the support wood is greater than the distance between the prefabricated panels.

[0016] Preferably, after the force-bearing plate descends along with the supporting plate, the force-bearing plate is located outside the pushing block. When the pushing block moves, the pushing block contacts the force-bearing plate, and the pushing block pushes the force-bearing plate, so that the force-bearing plate drives the supporting plate to move.

[0017] A method for using a stacking device for producing and processing prefabricated panels comprises the following steps:

[0018] Step 1: stacking, the prefabricated board moves from the surface of the conveyor belt with the conveyor belt, pushes the supporting wood on the surface of the second supporting plate to the surface of the supporting plate, the supporting plate supports the supporting wood, and the prefabricated board falls to the surface of the supporting wood. The gravity of the prefabricated board compresses the first spring in the lifting slot to play a buffering role, and the piston rod is driven to move by the cylinder, and the piston rod drives the lifting rod to move through the connecting rod to move the prefabricated board to the top of the first supporting plate, and the movable block moves down in the lifting slot so that the prefabricated board descends. When the supporting plate descends to the surface of the extension block, the L-shaped rod is squeezed, so that the L-shaped rod drives the top holding plate to move up, and the top holding plate is no longer held on the surface of the supporting plate, so that the force-bearing rod can move in the adjusting slot, and the cylinder in the extension block pushes the push block so that the push block is held on the surface of the force-bearing plate, and the force-bearing plate drives the support plate to move, and the support plate moves out from the bottom of the prefabricated board, so that the prefabricated board is stacked on the surface of the first supporting plate;

[0019] Step 2: Retract. When the prefabricated panels are stacked for the next time, due to the long length of the force-bearing panels, the pushing block can still be held on the surface of the force-bearing panels after moving, so that the support panels move. When the support panels rise, the pushing of the third spring makes the holding panels held on the surface of the support panels, and the force-bearing rods cannot move in the adjusting grooves. Therefore, the support panels will not be blocked by the stacked prefabricated panels during their rising process. When the support panels rise, the balls are inserted into the through holes, and the balls are held on the surface of the support panels. The balls hit the surface of the support panels, and due to inertia, the holding panels are not held on the surface of the support panels for a short time, so that the second spring pushes the force-bearing rods, so that the two groups of support panels approach each other, and the balls can roll on the ends of the holding rods, reducing the friction of the holding rods on the support panels, so that the support panels can support the supporting wood and prefabricated panels again.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The prefabricated panel proposed by the present invention moves from the surface of the conveyor belt along with the conveyor belt, pushes the supporting wood on the surface of the second supporting plate to the surface of the supporting plate, the supporting plate supports the supporting wood, and the prefabricated panel falls to the surface of the supporting wood. The gravity of the prefabricated panel compresses the first spring in the lifting groove to play a buffering role. The piston rod is driven to move by the cylinder, and the piston rod drives the lifting rod to move through the connecting rod to move the prefabricated panel to the top of the first supporting plate. The movable block moves downward in the lifting groove, so that the prefabricated panel descends. When the supporting plate descends to the surface of the extension block, the L-shaped rod is squeezed, so that the L-shaped rod drives the top holding plate to move upward, and the top holding plate is no longer held on the surface of the supporting plate, so that the force-bearing rod can move in the adjustment groove, and the cylinder in the extension block pushes the push block, so that the push block is held on the surface of the force-bearing plate, and the force-bearing plate drives the supporting plate to move, and the supporting plate moves out from the bottom of the prefabricated panel, so that the prefabricated panel is stacked on the surface of the first supporting plate, and there is no need to manually place the supporting wood. When the supporting wood is pushed to the surface of the prefabricated panel, it is limited by the limit rod to ensure the accuracy of the position of the supporting wood.

[0037] A groove 16 is provided on the surface of the vertical rod 13, and a supporting rod 15 is fixed on the surface of the vertical rod 13.

A cross bar 18 is fixed on the surface of the movable block 25, and the cross bar 18 moves with the movable block 25. The movable block 25 moves downward in the lifting groove 24, so that the prefabricated plate 2 descends. When the support plate 20 descends to the surface of the extension block 34, the L-shaped rod 30 is squeezed, so that the L-shaped rod 30 drives the supporting plate 29 to move upward.

[0038] Embodiment 3: A through hole 17 is provided on the surface of the cross bar 18, and the supporting rod 15 can be inserted into the through hole 17, and a force-bearing rod 23 is fixed to the bottom of the cross bar 18, and a lifting ring 31 is sleeved on the surface of the force-bearing rod 23, and the lifting ring 31 can be lifted and lowered on the surface of the force-bearing rod 23.

[0039] A top holding plate 29 is fixed on the surface of the L-shaped rod 30. The top holding plate 29 moves with the L-shaped rod 30. The top holding plate 29 is held on the surface of the support plate 20. After the top holding plate 29 moves with the L-shaped rod 30, it is no longer held on the surface of the support plate 20. An adjustment groove 27 is opened on the surface of the support plate 20. The force-bearing rod 23 is located in the adjustment groove 27, and the force-bearing rod 23 can move in the adjustment groove 27. The cross-section of the force-bearing rod 23 is T-shaped, and the cross-section of the adjustment groove 27 is also T-shaped. A second Spring 28, one end of the second spring 28 is connected to the inner wall of the adjustment groove 27, and the other end is connected to the surface of the force-bearing rod 23. The second spring 28 has a thrust on the force-bearing rod 23, and the ball 33 hits the surface of the support plate 20. Due to inertia, the supporting plate 29 is not supported on the surface of the support plate 20 for a short time, so that the second spring 28 pushes the force-bearing rod 23, so that the two groups of support plates 20 are close to each other, and the ball 33 can roll on the end of the supporting rod 15, reducing the friction of the supporting rod 15 on the support plate 20.

[0040] There are multiple groups of rollers 22 , which are distributed on the surface of the support plate 20 , and the rollers 22 can roll on the surface of the support plate 20 .

[0041] Embodiment 4: The prefabricated board 2 moves along with the conveyor belt 3, and the prefabricated board 2 falls to the top of the support plate 20 after moving. The distance between the two groups of support plates 20 is smaller than the width of the prefabricated board 2, and the supporting wood 8 on the surface of the second supporting plate 6 is pushed and moved to the surface of the supporting plate 20. The supporting wood 8 is located at the bottom of the prefabricated board 2, and the width of the supporting wood 8 is greater than the distance between the prefabricated boards 2. The supporting wood 8 on the surface of the second supporting plate 6 is pushed to the surface of the supporting plate 20, and the supporting plate 20 supports the supporting wood 8. The prefabricated board 2 falls to the surface of the supporting wood 8, and the gravity of the prefabricated board 2 causes the first spring 26 in the lifting slot 24 to be compressed, which plays a buffering role.

[0042] After the force-bearing plate 21 descends along with the supporting plate 20, the force-bearing plate 21 is located outside the pushing block 35. When the pushing block 35 moves, the pushing block 35 contacts the force-bearing plate 21, and the pushing block 35 pushes the force-bearing plate 21, so that the force-bearing plate 21 drives the supporting plate 20 to move. The cylinder in the extension block 34 pushes the pushing block 35, so that the pushing block 35 is supported on the surface of the force-bearing plate 21, and the force-bearing plate 21 drives the supporting plate 20 to move, and the supporting plate 20 moves out from the bottom of the precast plate 2, so that the precast plate 2 is stacked on the surface of the first supporting plate 5.

[0043] The prefabricated board 2 moves from the surface of the conveyor belt 3 along with the conveyor belt 3, pushing the supporting wood 8 on the surface of the second supporting plate 6 to the surface of the supporting plate 20. The supporting plate 20 supports the supporting wood 8, and the prefabricated board 2 falls on the surface of the supporting wood 8. The gravity of the prefabricated board 2 compresses the first spring 26 in the lifting groove 24, which plays a buffering role. The piston rod 12 is driven to move by the cylinder 11, and the piston rod 12 drives the lifting rod 9 to move through the connecting rod 10, moving the prefabricated board 2 to the top of the first supporting plate 5. The movable block 25 moves down in the lifting groove 24, so that the prefabricated board 2 descends. When the supporting plate 20 descends to the surface of the extension block 34, the L-shaped rod 30 is squeezed, so that the L-shaped rod 30 drives the top holding plate 29 The supporting plate 20 is moved upward, and the supporting plate 20 is no longer supported on the surface of the supporting plate 20, so that the force-bearing rod 23 can move in the adjusting groove 27. The cylinder in the extending block 34 pushes the pushing block 35, so that the pushing block 35 is supported on the surface of the force-bearing plate 21. The force-bearing plate 21 drives the supporting plate 20 to move, and the supporting plate 20 moves out from the bottom of the prefabricated plate 2, so that the prefabricated plate 2 is stacked on the surface of the first supporting plate 5. When the prefabricated plate 2 is stacked for the next time, due to the longer length of the force-bearing plate 21, the pushing block 35 can still be supported on the surface of the force-bearing plate 21 after moving, so that the supporting plate 20 moves. When the supporting plate 20 rises, the pushing of the third spring 32 causes the supporting plate 20 to push upward. The support plate 20 is held on the surface of the support plate 20, and the force-bearing rod 23 cannot move in the adjustment groove 27, so the support plate 20 will not be blocked by the stacked prefabricated panels 2 during the rising process. When the support plate 20 rises, the ball 33 is inserted into the through hole 17, and the ball 33 is held on the surface of the support plate 20. The ball 33 hits the surface of the support plate 20. Due to inertia, the supporting plate 29 is not held on the surface of the support plate 20 for a short time, so that the second spring 28 pushes the force-bearing rod 23, so that the two groups of support plates 20 are close to each other, and the ball 33 can roll on the end of the supporting rod 15, reducing the friction of the supporting rod 15 on the support plate 20, and the support plate 20 can support the support wood 8 and the prefabricated panel 2 again.

A stacking device for production and processing of prefabricated panels according to claim 3, characterized in that: The prefabricated panel (2) moves along with the conveyor belt (3), and the prefabricated panel (2) falls to the top of the support plate (20) after moving, and the distance between the two groups of support plates (20) is smaller than the width of the prefabricated panel (2), and the support wood (8) on the surface of the second support plate (6) is pushed and moved to the surface of the support plate (20), and the support wood (8) is located at the bottom of the prefabricated panel (2), and the width of the support wood (8) is greater than the distance between the prefabricated panels (2).

5. A stacking device for production and processing of prefabricated panels according to claim 4, characterized in that: After the force-bearing plate (21) descends along with the support plate (20), the force-bearing plate (21) is located outside the pushing block (35); when the pushing block (35) moves, the pushing block (35) contacts the force-bearing plate (21), and the pushing block (35) pushes the force-bearing plate (21), so that the force-bearing plate (21) drives the support plate (20) to move.

6. A method for using the stacking device for production and processing of prefabricated panels as claimed in claim 5, characterized in that: The following steps are involved: Step 1: stacking, the prefabricated board (2) moves along the conveyor belt (3) from the surface of the conveyor belt (3), pushes the supporting wood (8) on the surface of the second supporting plate (6) to the surface of the supporting plate (20), the supporting plate (20) supports the supporting wood (8), the prefabricated board (2) falls on the surface of the supporting wood (8), the gravity of the prefabricated board (2) causes the first spring (26) in the lifting groove (24) to be compressed, playing a buffering role, and the piston rod (12) is driven to move by the cylinder (11), and the piston rod (12) drives the lifting rod (9) to move through the connecting rod (10), so that the prefabricated board (2) is moved to the top of the first supporting plate (5), and the movable block (25) is in the lifting groove (24). The precast plate (2) moves downward, so that when the support plate (20) descends to the surface of the extension block (34), the L-shaped rod (30) is squeezed, so that the L-shaped rod (30) drives the top holding plate (29) to move upward, and the top holding plate (29) is no longer supported on the surface of the support plate (20), so that the force rod (23) can move in the adjustment groove (27), and the cylinder in the extension block (34) drives the push block (35), so that the push block (35) is supported on the surface of the force plate (21), and the force plate (21) drives the support plate (20) to move, and the support plate (20) moves out from the bottom of the precast plate (2), so that the precast plate (2) is stacked on the surface of the first supporting plate (5); Step 2: Retract. When the prefabricated panels (2) are stacked for the next time, since the load-bearing panel (21) is relatively long, the pushing block (35) can still be supported on the surface of the load-bearing panel (21) after moving, so that the support panel (20) moves. When the support panel (20) rises, the push of the third spring (32) causes the supporting panel (29) to be supported on the surface of the support panel (20). The load-bearing rod (23) cannot move in the adjusting groove (27). Therefore, the support panel (20) will not be blocked by the stacked prefabricated panels (2) during its rising process. When the support panel (20) rises, the ball bearing ( The supporting plate (20) is inserted into the through hole (17), and the ball (33) is supported on the surface of the supporting plate (20). The ball (33) hits the surface of the supporting plate (20). Due to inertia, the supporting plate (29) is not supported on the surface of the supporting plate (20) for a short time, so that the second spring (28) pushes the force-bearing rod (23), so that the two groups of supporting plates (20) are close to each other, and the ball (33) can roll on the end of the supporting rod (15), reducing the friction of the supporting rod (15) on the supporting plate (20), so that the supporting plate (20) can support the supporting wood (8) and the prefabricated board (2) again.
