Description

Technical Field

[0001] This utility model relates to the field of logistics technology, specifically to a pallet stacking and shaping device and an integrated equipment for stacking and shaping pallets. Background Technology

[0002] Pallets, as strategic equipment in the logistics process, are the medium that transforms static goods into dynamic goods.

[0003] A pallet stacking machine is a device used to stack and separate pallets. Its function is to stack pallets transferred from the previous level of the logistics system to form a pallet stack, which aims to save floor space. When pallets are needed, empty pallets are separated from the pallet stack for use by the next level of the logistics system.

[0004] After pallet stacking or splitting operations, the pallet stack is prone to misalignment and tilting due to the vibration of the stacking or splitting actions, which increases the risk of pallet stack collapse and reduces the stability of the pallet stack. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention proposes a pallet stacking shaping device and an integrated pallet stacking and shaping equipment. This invention can flatten the four sides of the pallet stack, prevent misalignment and skewing, reduce the risk of pallet stack collapse, and improve the stability of the pallet stack.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pallet stacking shaping device includes a frame and two sets of shaping mechanisms;

[0008] The middle section of the frame is used to accommodate pallet stacks;

[0009] Each of the shaping mechanisms includes at least two sets of rotating abutment components and a drive structure for driving the rotating abutment components. The rotating abutment component includes a rotating shaft and shaping rods fixed to the rotating shaft. The rotating shaft is rotatably connected to the frame. The drive structure drives all shaping rods to swing towards the pallet stack or away from the pallet stack through the rotating shaft. During the swinging process, the shaping rods are in a state of contact with the pallet stack.

[0010] The shaping rods in one set of the shaping mechanisms are used to abut against the two sides of the pallet stack along the first direction, and the shaping rods in the other set of the shaping mechanisms are used to abut against the two sides of the pallet stack along the second direction.

[0011] Furthermore, each set of the shaping mechanism includes two of the rotating abutment components, wherein the shaping rod in the two rotating abutment components abuts against the middle of the side of the pallet stack;

[0012] Alternatively, each of the shaping mechanisms may include four of the rotating abutment components, with the shaping rod of one of the four rotating abutment components abutting at the side corner of the pallet stack.

[0013] Furthermore, the rotating shaft is connected to the shaping rod via a connecting rod, and the connecting rod is an arc-shaped rod with its concave side facing the pallet stack.

[0014] Furthermore, the drive structure is one of the following: a linkage mechanism, a synchronous belt mechanism, or a gear and rack mechanism.

[0015] Furthermore, the drive structure includes a power assembly, two moving parts, a connecting rod, and a swing rod. The power assembly is used to drive the two moving parts to move closer to each other and further away from each other. The two moving parts correspond to two opposite sides of the pallet stack. The two ends of the connecting rod are hinged to the moving parts and the swing rod, respectively. The swing rod is fixedly connected to the rotating shaft at the end away from the connecting rod.

[0016] Furthermore, the power assembly includes a lead screw, a drive component, a slide rail, and a slider. The end of the lead screw is rotatably connected to the frame. The drive component is used to drive the lead screw to rotate. Two moving components from the drive structure are threadedly connected to the lead screw. The slider is provided on the moving component. The slide rail is located on the frame, and the slider is slidably connected to the slide rail.

[0017] Furthermore, the drive structure includes a synchronous belt and a drive motor. The synchronous belt connects all the rotating shafts in series via synchronous pulleys. The rotating shafts are directly connected to the synchronous pulleys or connected to the synchronous pulleys via a rotary commutator, so that all the shaping rods move synchronously closer to or away from the pallet stack.

[0018] A pallet stacking and shaping integrated equipment includes a conveying device, a pallet stacking and shaping device, wherein the conveying device passes through the bottom of the frame and is used to convey pallets along a first direction, the shaping rod is located above the conveying device, and the pallet stacking and shaping device is provided on both sides of the conveying device.

[0019] Furthermore, the conveying device is one of a belt conveyor, a chain conveyor, and a roller conveyor. The front and / or rear sides of the conveying direction of the conveying device are provided with a lifting blocking structure, which includes a lifting baffle and a lifting drive component for driving the lifting baffle to rise and fall.

[0020] Furthermore, the stacking and unstacking device includes a lifting mechanism and an extension mechanism. The lifting mechanism includes a lifting frame and a lifting drive, the lifting drive being used to drive the lifting frame to rise and fall. The extension mechanism includes a side fork mounted on the lifting frame and an extension drive for driving the side fork to move forward and backward.

[0021] This utility model has the following beneficial effects:

[0022] In this device, the first of the two shaping mechanisms can level the front and rear sides of the pallet stack along the first direction, and the second shaping mechanism can level the left and right sides of the pallet stack along the second direction, preventing the pallet stack from becoming misaligned or skewed, reducing the risk of the pallet stack collapsing, improving the stability of the pallet stack, and thus improving the reliability of logistics operations.

[0039] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Example 1:

[0041] See Figures 1 to 4 A pallet stacking shaping device includes a frame 1 and two sets of shaping mechanisms.

[0042] The central space of rack 1 is used to accommodate pallet stacks.

[0043] A pallet stack is formed by stacking several pallets 2 vertically. The four sides of the pallet stack are the front side 21, the rear side, the left side, and the right side 22. The first direction is a straight line from front to back, and the second direction is a straight line from left to right. The first direction and the second direction are perpendicular. The sides of the pallet stack along (i.e. through) the first direction include the front side 21 and the rear side, and the sides of the pallet stack along the second direction include the left side and the right side 22.

[0044] Both shaping mechanisms include at least two sets of rotating abutment components and a drive structure for driving the rotating abutment components. The rotating abutment components include a rotating shaft and shaping rods fixed to the rotating shaft. The rotating shaft is rotatably connected to the frame 1. The drive structure drives all shaping rods to swing towards the pallet stack or away from the pallet stack through the rotating shaft. During the swinging process, the shaping rods are in a state of contact with the pallet stack.

[0045] Furthermore, each shaping mechanism includes two rotating abutment components, with the shaping rods of the two rotating abutment components abutting the center of the side of the pallet stack. Alternatively, each shaping mechanism includes four rotating abutment components, with the shaping rods of the four rotating abutment components abutting the corners of the side of the pallet stack.

[0046] One set of shaping mechanisms has shaping rods that abut against the two sides of the pallet stack along the first direction, while another set of shaping mechanisms has shaping rods that abut against the two sides of the pallet stack along the second direction.

[0047] For ease of distinction and description, the two shaping mechanisms are referred to as the first shaping mechanism and the second shaping mechanism, respectively, and the structures in the first shaping mechanism and the second shaping mechanism are also distinguished by the terms "first" and "second," respectively.

[0048] The first shaping mechanism is used to flatten the front and rear sides of the pallet stack.

[0049] See Figure 1 The first shaping mechanism includes a first drive structure and four first rotating abutment components.

[0050] See Figure 1 Each of the four first rotating abutment assemblies includes a first rotating shaft 31 and a first shaping rod 32. The first rotating shafts 31 are respectively located at the four corners of the pallet stack, and the bottoms of the four first rotating shafts 31 are rotatably connected to the bottom of the frame 1 via bearing seats. A first connecting rod 33 is fixedly installed on the side of each of the four first rotating shafts 31. The first connecting rod 33 is an arc-shaped rod, with its concave side facing the pallet stack. A first shaping rod 32 is fixedly installed at the end of the first connecting rod 33 furthest from the first rotating shaft 31.

[0051] See Figure 1 The first drive structure is mounted on the top of the frame 1 and is used to drive the four first rotating shafts 31 to rotate synchronously. The first drive structure includes a first power assembly, two first moving parts 34, a first connecting rod 35, and a first swing rod 36. The first power assembly is used to drive the two first moving parts 34 to move closer to each other and further away from each other. The first moving part 34 is a rod structure, and the first connecting rod 35 is rotatably connected to both ends of the first moving part 34. The first swing rod 36 is rotatably connected to the end of the first connecting rod 35 away from the first moving part 34. The end of the first swing rod 36 away from the first connecting rod 35 is fixedly connected to the top of the first rotating shaft 31.

[0052] The working principle of the first plastic surgery mechanism is as follows:

[0053] When the first power assembly drives the two first moving parts 34 to approach each other, both first moving parts 34 pull the first swing rod 36 through the first connecting rod 35, causing the first swing rod 36 to drive the first rotating shaft 31 to rotate. The first rotating shaft 31 drives the first shaping rod 32 to swing toward the pallet stack through the first connecting rod 33. The first shaping rod 32 pushes the pallet stack along the side of the first direction (including the front side 21 and the rear side), so that the pallet stack is aligned and flattened along the side of the first direction.

[0054] Conversely, when the first power assembly drives the two first moving parts 34 away from each other, both first moving parts 34 push the first swing rod 36 through the first connecting rod 35, causing the first swing rod 36 to drive the first rotating shaft 31 to rotate in the opposite direction. The first rotating shaft 31 drives the first connecting rod 33 and the first shaping rod 32 to swing away from the pallet stack, so that the first shaping rod 32 leaves the side of the pallet stack along the first direction. At this time, the first shaping rod 32 will not prevent the pallet 2 in the pallet stack from leaving along the first direction.

[0055] See Figure 1 The first power assembly includes a first lead screw, a first drive member 38, a first slide rail 39, and a first slider 310. In this embodiment 1, the first lead screw includes two first lead screw units 37 with opposite thread directions. Both ends of the first lead screw unit 37 are rotatably mounted on the top of the frame 1 via bearing seats. In this embodiment 1, the first drive member 38 can be a dual-output motor. The dual-output motor is fixedly mounted on the top of the frame 1 and is located between the two first lead screw units 37. The dual-output motor has two output shafts, which are respectively connected to the two first lead screw units 37 via couplings, so that the dual-output motor can drive the two first lead screw units 37 to rotate synchronously. A first threaded seat 341 is fixedly mounted on the center of the top surface of each of the two first moving members 34, and the two first lead screw units 37 are respectively threadedly connected to the first threaded seats 341 on the two first moving members 34. The bottom surface of the first moving part 34 is fixedly mounted with a first slider 310, and the top of the frame 1 is fixedly mounted with a first slide rail 39. The first slider 310 is slidably connected to the first slide rail 39.

[0056] The working principle of the first power unit is as follows:

[0057] The dual-output motor, acting as the first driving element 38, drives the two first lead screw units 37 to rotate synchronously in the forward direction. Each of the two first lead screw units 37 drives a first moving part 34 to move closer to the dual-output motor, causing the two first moving parts 34 to move closer to each other. Conversely, when both first lead screw units 37 rotate in the reverse direction, each of the two first lead screw units 37 drives a first moving part 34 to move away from the dual-output motor, causing the two first moving parts 34 to move away from each other.

[0058] Besides using a dual-output motor as the first driving element 38, this embodiment 1 also provides a second structure for the first driving element 38. This second type of first driving element 38 includes a single-output motor and a dual-output reducer. The single-output motor has one output shaft, and the dual-output reducer has two output shafts. The output shaft of the single-output motor is connected to the input end of the dual-output reducer, and the two output shafts of the dual-output reducer are respectively connected to two first lead screw units 37 via couplings. After being reduced in speed by the dual-output reducer, the single-output motor drives the two first lead screw units 37 to rotate synchronously. The dual-output motor, single-output motor, and dual-output reducer in this embodiment 1 are all existing, mature devices.

[0059] The first lead screw in this embodiment 1 includes two first lead screw units 37. In addition, this embodiment 1 also provides a second structure for the first lead screw. The second type of first lead screw adopts a rod with two sections of oppositely helical threads. The second type of first lead screw is threadedly connected to two first moving parts 34. In order to cooperate with the second type of first lead screw, the first driving part 38 adopts a single-output motor. The output shaft of the single-output unit is connected to one end of the second type of first lead screw through a coupling. The second type of first lead screw is driven to rotate by this single-output motor, and the second type of first lead screw drives the two first moving parts 34 to move.

[0060] The second shaping mechanism is used to level the left and right sides 22 of the pallet stack.

[0061] See Figure 2 The second shaping mechanism includes a second drive structure and four second rotating abutment components.

[0062] See Figure 2 Each of the four second rotating abutment assemblies includes a second rotating shaft 41 and a second shaping rod 42. The second rotating shafts 41 are respectively located at the four corners of the pallet stack, and the tops of the four second rotating shafts 41 are rotatably connected to the top of the frame 1 via bearing seats. Second connecting rods 43 are fixedly installed on the sides of the four second rotating shafts 41. In this embodiment 1, the second connecting rods 43 are straight rods, and the second shaping rod 42 is fixedly installed at the end of the second connecting rod 43 away from the second rotating shaft 41. Alternatively, the second connecting rod 43 can also be an arc-shaped rod; when using an arc-shaped rod as the second connecting rod 43, the concave side of the second connecting rod 43 faces the pallet stack.

[0063] See Figure 2The second drive structure is installed at the bottom of the frame 1 and is used to drive the four second rotating shafts 41 to rotate synchronously. The second drive structure includes a second power assembly, two second moving parts 44, a second connecting rod 45, and a second swing rod 46. The second power assembly is used to drive the two second moving parts 44 to move closer to each other and further away from each other. The second moving part 44 is a rod structure, and the two ends of the second moving part 44 are rotatably connected to the second connecting rod 45. The second swing rod 46 is rotatably connected to the end of the second connecting rod 45 away from the second moving part 44. The end of the second swing rod 46 away from the second connecting rod 45 is fixedly connected to the bottom of the second rotating shaft 41.

[0064] The working principle of the second shaping mechanism is as follows:

[0065] When the second power assembly drives the two second moving parts 44 to approach each other, both second moving parts 44 pull the second swing rod 46 through the second connecting rod 45, causing the second swing rod 46 to drive the second rotating shaft 41 to rotate. The second rotating shaft 41 drives the second shaping rod 42 to swing toward the pallet stack through the second connecting rod 43. The second shaping rod 42 pushes the pallet stack along the side of the second direction (including the left side and right side 22), so that the pallet stack is aligned and flattened along the side of the second direction.

[0066] Conversely, when the second power assembly drives the two second moving parts 44 away from each other, both second moving parts 44 push the second swing rod 46 through the second connecting rod 45, causing the second swing rod 46 to drive the second rotating shaft 41 to rotate in the opposite direction. The second rotating shaft 41 drives the second connecting rod 43 and the second shaping rod 42 to swing away from the pallet stack, causing the second shaping rod 42 to leave the side of the pallet stack along the second direction.

[0067] See Figure 2 The second power assembly includes a second lead screw, a second drive member 48, a second slide rail 49, and a second slider 410. In this embodiment 1, the second lead screw includes two second lead screw units 47 with opposite thread directions. Both ends of the second lead screw units 47 are rotatably mounted on the bottom of the frame 1 via bearing seats. The second drive member 48 can be a dual-output motor, which is fixedly mounted on the bottom of the frame 1 and located between the two second lead screw units 47. The dual-output motor has two output shafts, which are respectively connected to the two second lead screw units 47 via couplings. The dual-output motor can drive the two second lead screw units 47 to rotate synchronously. A second threaded seat 441 is fixedly mounted on the center of the top surface of each of the two second moving members 44. The two second lead screw units 47 are respectively threadedly connected to the second threaded seats 441 on the two second moving members 44. A second slider 410 is fixedly mounted on the bottom surface of the second moving member 44, and a second slide rail 49 is fixedly mounted on the bottom of the frame 1. The second slider 410 is slidably connected to the second slide rail 49.

[0068] The working principle of the second power unit is as follows:

[0069] The dual-output motor, acting as the second driving element 48, drives two second lead screw units 47 to rotate synchronously in the forward direction. Each of the two second lead screw units 47 drives a second moving part 44 to move closer to the dual-output motor, causing the two second moving parts 44 to move closer to each other. Conversely, when both second lead screw units 47 rotate in the reverse direction, each of the two second lead screw units 47 drives a second moving part 44 to move away from the dual-output motor, causing the two second moving parts 44 to move away from each other.

[0070] The working principle of this device for leveling pallet stacks is as follows:

[0071] The first power assembly drives two first moving parts 34 to move closer to each other. Both first moving parts 34 pull the first swing rod 36 through the first connecting rod 35, causing the first swing rod 36 to drive the first rotating shaft 31 to rotate. The first rotating shaft 31 drives the first shaping rod 32 to swing toward the pallet stack through the first connecting rod 33. The first shaping rod 32 pushes the pallet stack along the side of the first direction (including the front side 21 and the rear side), so that the pallet stack is aligned and flattened along the side of the first direction.

[0072] Simultaneously, the second power assembly drives the two second moving parts 44 to move closer to each other. Both second moving parts 44 pull the second swing rod 46 through the second connecting rod 45, causing the second swing rod 46 to drive the second rotating shaft 41 to rotate. The second rotating shaft 41 drives the second shaping rod 42 to swing toward the pallet stack through the second connecting rod 43. The second shaping rod 42 pushes the pallet stack along the side of the second direction (including the left side and right side 22), so that the pallet stack is aligned and flattened along the side of the second direction.

[0073] After leveling the pallet stack, the working principle of this device's reset mechanism is as follows:

[0074] The first power assembly drives two first moving parts 34 to move away from each other. Both first moving parts 34 push the first swing rod 36 through the first connecting rod 35, causing the first swing rod 36 to drive the first rotating shaft 31 to rotate in the opposite direction. The first rotating shaft 31 drives the first connecting rod 33 and the first shaping rod 32 to swing away from the pallet stack, so that the first shaping rod 32 leaves the side of the pallet stack along the first direction. At this time, the first shaping rod 32 will not prevent the pallet 2 in the pallet stack from leaving along the first direction.

[0075] At the same time, the second power assembly drives the two second moving parts 44 to move away from each other. Both second moving parts 44 push the second swing rod 46 through the second connecting rod 45, so that the second swing rod 46 drives the second rotating shaft 41 to rotate in the opposite direction. The second rotating shaft 41 drives the second connecting rod 43 and the second shaping rod 42 to swing away from the pallet stack, so that the second shaping rod 42 leaves the side of the pallet stack along the second direction.

[0076] Based on the above working principle, it can be seen that this device has the following advantages:

[0077] First, in this device, the first shaping mechanism of the two shaping mechanisms can flatten the front side 21 and rear side of the pallet stack along the first direction, and the second shaping mechanism can flatten the left side and right side 22 of the pallet stack along the second direction, so as to prevent the pallet stack from being misaligned or tilted, reduce the risk of the pallet stack collapsing, improve the stability of the pallet stack, and thus improve the reliability of logistics operations.

[0078] Secondly, in this device, the first drive structure in the first shaping mechanism can drive four first rotating shafts 31 to rotate synchronously, which in turn can drive four first shaping rods 32 to simultaneously push the front side 21 and rear side of the pallet stack along the first direction, so that the front side 21 and rear side of the pallet stack along the first direction are leveled simultaneously, which helps to improve the leveling efficiency. Similarly, the second drive structure in the second shaping mechanism can drive four second rotating shafts 41 to rotate synchronously, which in turn can drive four second shaping rods 42 to simultaneously push the left side and right side 22 of the pallet stack along the second direction, so that the left side and right side 22 of the pallet stack along the second direction are leveled simultaneously, which helps to improve the leveling efficiency.

[0079] Third, because the first drive structure in the first shaping mechanism can drive the four first rotating shafts 31 to rotate synchronously, and the second drive structure in the second shaping mechanism can drive the four second rotating shafts 41 to rotate synchronously, the number of power sources can be reduced, which is beneficial to saving energy.

[0080] Example 2:

[0081] In Embodiment 1, the drive structure (first drive structure, second drive structure) drives the rotating shaft to rotate through a linkage mechanism formed by a power component, a moving part, a connecting rod, and a swing rod. Alternatively, the drive structure may employ a synchronous belt mechanism or a rack and pinion mechanism.

[0082] When the drive structure adopts a synchronous belt mechanism, the drive structure includes a synchronous belt 83 and a drive motor 81. The synchronous belt 83 connects all the rotating shafts in series through the synchronous pulley 82. The rotating shafts are directly connected to the synchronous pulley 82 or connected to the synchronous pulley 82 through a rotary commutator 84, so that all the shaping rods move towards or away from the pallet stack synchronously.

[0083] For example, see Figure 6 When the first drive structure drives the four first rotating shafts 31 to rotate using the synchronous belt mechanism, the first rotating shafts 31 at the upper left and lower right corners are directly connected to the synchronous belt pulleys 82 (for example, they can be directly welded and fixed, or connected using a coupling), and the first rotating shafts 31 at the lower left and upper right corners are connected to the synchronous belt pulleys 82 through the rotation commutator 84.

[0084] See Figure 7 The commutator is a type of commutator where the input shaft 841 rotates in opposite directions to the output shaft 842. A synchronous pulley 82 is fixedly mounted on the input shaft 841, and the first rotating shafts 31 at the lower left and upper right corners are both fixedly connected to the output shaft 842. Specifically, a first bevel gear 843 is coaxially mounted on the input shaft 841, and a second bevel gear 844 is coaxially mounted on the output shaft 842. The first bevel gear 843 and the second bevel gear 844 mesh with the same intermediate gear 845. After transmission through the first bevel gear 843, the intermediate gear 845, and the second bevel gear 844, the input shaft 841 and the output shaft 842 rotate in opposite directions.

[0085] See Figure 6 The synchronous pulleys 82 at the top of the four first rotating shafts 31 are driven by the same synchronous belt 83. The drive motor 81 is mounted on the top of the frame 1, and the output end of the drive motor 81 is connected to a reducer 811. The output end of the reducer 811 is equipped with a drive pulley 812. The synchronous belt 83 also passes around the drive pulley 812. The drive motor 81 drives the drive pulley 812 to rotate after being reduced in speed by the reducer 811. The drive pulley 812 drives the four synchronous pulleys 82 to rotate together in the same direction through the synchronous belt 83. Since two synchronous pulleys 82 are directly connected to the first rotating shafts 31, and the other two synchronous pulleys 82 are connected to the first rotating shafts 31 through a rotary reversing device 84, the four first rotating shafts 31 can rotate relative to each other in pairs, so that the four first shaping rods 32 abut against the pallet stack in pairs, realizing the leveling operation of the pallet stack on both sides along the first direction.

[0086] The driving structure described in Embodiment 2, like the driving structure in Embodiment 1, uses one power source to drive four rotating shafts. This improves the synchronization of the four rotating shafts and reduces the number of power sources, which helps save energy.

[0087] Furthermore, this application does not impose any restrictions on the drive structure as long as the shaft can rotate.

[0088] Example 3:

[0089] See Figure 4 and Figure 5 A pallet stacking and shaping integrated equipment includes a conveying device, a pallet stacking and shaping device of Example 1.

[0090] The conveying device passes through the bottom of the frame 1 and is used to convey the pallet 2 along a first direction. The first shaping rod 32 and the second shaping rod 42 are both located above the conveying device. When the first shaping rod 32 and the second shaping rod 42 align and level the pallet stack, their movement is not obstructed by the conveying device because they are both located above it.

[0091] The conveying device is one of a belt conveyor, a chain conveyor, or a roller conveyor. In this embodiment 3, the conveying device includes two belt conveyors 51, but it can also be replaced by a chain conveyor or a roller conveyor. When transporting the pallet 2, the left and right sides of the pallet 2 are respectively located on the two belt conveyors 51.

[0092] The conveying device is provided with a lifting blocking structure on the front and / or rear side of the conveying direction. The lifting blocking structure includes a lifting baffle and a lifting drive component for driving the lifting baffle to rise and fall.

[0093] In this embodiment 3, lifting blocking structures are provided on both the front and rear sides of the conveying device in the conveying direction. Two lifting blocking structures are located between two belt conveyors 51, and are respectively referred to as the first lifting blocking structure and the second lifting blocking structure. The structures within the two lifting blocking structures are also distinguished by the designations "first" and "second". The first lifting blocking structure includes a first lifting baffle 52 and a first lifting drive member for driving the first lifting baffle 52 to rise and fall. The second lifting blocking structure includes a second lifting baffle and a second lifting drive member for driving the second lifting baffle to rise and fall.

[0094] Both the first and second lifting drive components can be lifting devices such as hydraulic cylinders or pneumatic cylinders. Both the first and second lifting drive components are fixedly installed at the bottom of the frame 1. A first lifting baffle 52 is installed on the piston rod of the first lifting drive component, and a second lifting baffle is installed on the piston rod of the second lifting drive component.

[0095] When pallet 2 is conveyed from front to back, the first lifting drive unit lowers the first lifting baffle 52 to prevent it from obstructing the pallet 2 from passing through, and the second lifting drive unit raises the second lifting baffle. When the rear side of pallet 2 abuts against the second lifting baffle, it indicates that pallet 2 has been conveyed to the correct position. After pallet 2 has been conveyed to the correct position, the first lifting drive unit raises the first lifting baffle 52 again, so that the first lifting baffle 52 blocks the front side of pallet 2, which can stabilize the position of pallet 2 between the first lifting baffle 52 and the second lifting baffle.

[0096] As the pallet 2 is being transported away, the second lifting drive unit lowers the height of the second lifting baffle, and the two second belt conveyors 51 continue to transport the pallet 2 backward.

[0097] The conveyor is equipped with destacking and palletizing devices on both the left and right sides. The destacking and palletizing devices include a lifting mechanism and an extension fork mechanism.

[0098] See Figure 4 and Figure 5 The lifting mechanism includes a lifting frame 61 and a lifting drive component for driving the lifting frame 61 to rise and fall. The lifting frame 61 has an L-shaped structure. In this embodiment 3, the lifting drive component includes a synchronous shaft 62, a lifting pulley 63, and a lifting belt 64. The synchronous shaft 62 is rotatably mounted on the bottom of the frame 1 via a bearing seat, and the synchronous shaft 62 is located above the second lead screw unit 47. A lifting motor is also fixedly mounted on the bottom of the frame 1, and the lifting motor drives the synchronous shaft 62 to rotate. A first lifting pulley 63 is fixedly mounted on one end of the synchronous shaft 62, a second lifting pulley 63 is rotatably mounted on the upper part of the frame 1, and one end of the lifting belt 64 (e.g., a belt) is fixedly mounted on the bottom of the lifting frame 61. The other end of the lifting belt 64 passes sequentially around the first lifting pulley 63 and the second lifting pulley 63 before being fixedly mounted on the top of the lifting frame 61. Furthermore, when the lifting belt 64 passes around the two lifting pulleys 63, it will pass through the pre-drilled hole 611 on the lifting frame 61. When the lifting belt 64 is fixed to the lifting frame 61, it can be fixed with bolts or other fasteners.

[0099] The working principle of the lifting mechanism is as follows:

[0100] When the synchronous shaft 62 drives the first lifting pulley 63 to rotate forward under the drive of the lifting motor, it drives the second lifting pulley 63 to rotate forward through the transmission of the lifting belt 64, so that the lifting belt 64 rotates around the two lifting pulleys 63. During this process, the lifting belt 64 drives the lifting frame 61 to move downward. Conversely, when the synchronous shaft 62 drives the first lifting pulley 63 to rotate in reverse, the lifting belt 64 drives the lifting frame 61 to move upward.

[0101] In the aforementioned lifting mechanism, because the first lifting pulley 63 is fixedly installed at only one end of the synchronous shaft 62, the synchronicity of the lifting frames 61 located on both sides of the conveying device needs to be improved. To address this, the first lifting pulley 63 can be fixedly installed at both ends of the synchronous shaft 62. When the lifting motor drives the synchronous shaft 62 to rotate, the first lifting pulleys 63 at both ends of the synchronous shaft 62 rotate synchronously. Through the transmission of the lifting belt 64, the lifting frames 61 located on both sides of the conveying device rise and fall synchronously.

[0102] As long as the lifting frame 61 can be raised and lowered, this application does not impose any restrictions on the lifting drive components. For example, a cylinder, hydraulic cylinder, or other equipment can be used to drive the lifting frame 61 to rise and fall. The cylinder is fixedly mounted on the frame 1, and the lifting frame 61 is fixedly mounted on the piston rod of the cylinder. The lifting frame 61 is driven to rise and fall by the extension and retraction of the cylinder piston rod. Alternatively, the lifting belt 64 can be replaced by a chain, which can be fixed to the lifting frame 61 by welding. The lifting pulley 63 can be replaced by a sprocket. Yet another example is that the lifting belt 64 can be replaced by a wire rope, and the lifting pulley 63 can be replaced by a rope pulley.

[0103] See Figure 5 The fork extension mechanism includes a side fork 71 and an extension drive for driving the side fork 71 forward and backward. The side fork 71 is slidably connected to the lifting frame 61 along a second direction. In this embodiment 3, the extension drive includes an extension motor, a crank 72, and a synchronizing rod 73. The extension motor is installed at the bottom of the lifting frame 61, and the output shaft of the extension motor passes through the bottom of the lifting frame 61. The crank 72 is fixedly installed on the output shaft of the extension motor, and a roller 721 is rotatably installed at the other end of the crank 72. The synchronizing rod 73 is fixedly installed on the top surface of the side fork 71, and an elongated hole 731 is provided on the synchronizing rod 73, with the roller 721 disposed in the elongated hole 731.

[0104] The working principle of the extension mechanism is as follows:

[0105] The extension fork motor drives the crank 72 to rotate, which in turn drives the roller 721 to rotate. Since the roller 721 is located within the elongated hole 731 of the synchronizing rod 73, it pushes against the wall of the hole 731. When the end of the crank 72 with the roller 721 swings towards the conveyor belt 51, the roller 721 pushes the synchronizing rod 73 closer to the conveyor belt 51 by pushing against the wall of the elongated hole 731. The synchronizing rod 73 then moves the side fork 71 closer to the conveyor belt 51, allowing the side fork 71 to advance and insert into the slot of the tray 2 on the conveyor belt 51. When the end of the crank 72 with the roller 721 swings to its furthest position from the conveyor belt 51, the roller 721 pushes the synchronizing rod 73 away from the conveyor belt 51 by pushing against the wall of the elongated hole 731. The synchronizing rod 73 then moves the side fork 71 away from the conveyor belt 51, causing the side fork 71 to retract away from the tray 2. Each revolution of the crank 72 completes one forward and one backward movement for the side fork 71.

[0106] This application does not restrict the extension fork drive component as long as the side fork 71 can move forward and backward. For example, a cylinder, hydraulic cylinder, or other device can be used to drive the side fork 71 forward and backward.

[0107] The working principle of the integrated destacking and shaping device for stacked trays in this embodiment 3 is as follows:

[0108] (1) Stacking process:

[0109] S1. The first pallet 2 is conveyed from front to back into the frame 1 by the belt conveyor 51. When the first pallet 2 enters the frame 1, the first lifting drive unit lowers the first lifting baffle 52, and the second lifting drive unit raises the second lifting baffle. When the rear side of the first pallet 2 abuts against the second lifting baffle, the belt conveyor 51 stops, and the first lifting drive unit raises the first lifting baffle 52 again, so that the first pallet 2 is limited between the first lifting baffle 52 and the second lifting baffle.

[0110] S2. The lifting drive unit drives the lifting frame 61 to move down, the lifting frame 61 drives the extension fork mechanism to move down, the extension fork drive unit in the extension fork mechanism drives the side fork 71 to move forward and insert into the slot of the first pallet 2, lifting the first pallet 2; then the lifting drive unit drives the lifting frame 61 to rise, the lifting frame 61 drives the side fork 71 and the first pallet 2 supported by the side fork 71 to rise together, the first pallet 2 rises away from the belt conveyor 51.

[0111] S3. The second pallet 2 is conveyed from front to back into the frame 1 by the belt conveyor 51. When the second pallet 2 enters the frame 1, the first lifting drive unit lowers the first lifting baffle 52. When the rear side of the second pallet 2 abuts against the second lifting baffle, the belt conveyor 51 stops, and the first lifting drive unit lifts the first lifting baffle 52 again, so that the second pallet 2 is limited between the first lifting baffle 52 and the second lifting baffle.

[0112] S4. The lifting drive unit drives the lifting frame 61 to move downwards, which in turn drives the extension fork mechanism to move downwards. The side fork 71 in the extension fork mechanism supports the first pallet 2 and moves downwards, so that the first pallet 2 falls onto the top surface of the second pallet 2. The extension fork drive unit then drives the side fork 71 to disengage from the slot of the first pallet 2. Next, the lifting drive unit drives the lifting frame 61 to continue moving downwards, so that the height of the side fork 71 on the lifting frame 61 can reach the height of the slot of the second pallet 2. Then, the extension fork drive unit drives the side fork 71 to move forward and insert it into the slot of the second pallet 2. Finally, the lifting drive unit drives the lifting frame 61 to rise, which in turn drives the side fork 71 to move upwards. The side fork 71 lifts the pallet stack formed by the first pallet 2 and the second pallet 2 together and moves upwards. The second pallet 2 in the pallet stack rises away from the conveyor belt 51 so that the conveyor belt 51 can continue to transport the third pallet 2. This process is repeated until the required number of pallets is reached.

[0113] S5. The pallet stacking shaping device of Example 1 flattens and aligns the four sides of the pallet stack.

[0114] (2) Destacking process:

[0115] S1. The lifting drive unit drives the lifting frame 61 to descend, and the lifting frame 61 drives the extension fork mechanism to move down. The side fork 71 in the extension fork mechanism carries the pallet stack down to the belt conveyor 51. Then, the extension fork drive unit drives the side fork 71 to disengage from the slot of the last pallet 2 in the pallet stack. After that, the lifting drive unit drives the lifting frame 61 to rise by the height of one pallet 2. Next, the extension fork drive unit drives the side fork 71 to move forward and inserts the side fork 71 into the slot of the second to last pallet 2 in the pallet stack. Finally, the lifting drive unit drives the lifting frame 61 to move up, and the lifting frame 61 drives the extension fork mechanism to move up. The side fork 71 in the extension fork mechanism carries the pallet stack up, leaving the last pallet 2 on the belt conveyor 51.

[0116] S2, the second lifting drive unit lowers the height of the second lifting baffle, and the two second belt conveyors 51 continue to transport the last pallet 2 backward; after the last pallet 2 leaves, the second lifting drive unit drives the second lifting baffle to rise and reset.

[0117] S3. The lifting drive unit drives the lifting frame 61 to descend, and the lifting frame 61 drives the extension fork mechanism to move downward. The side fork 71 in the extension fork mechanism carries the pallet stack down to the belt conveyor 51. The original second-to-last pallet 2 becomes the new first-to-last pallet 2, and the original third-to-last pallet 2 becomes the new second-to-last pallet 2. Then, the extension fork drive unit drives the side fork 71 to disengage from the slot of the new first-to-last pallet 2 in the pallet stack. After that, the lifting drive unit drives the lifting frame 61 to rise by the height of one pallet 2. Next, the extension fork drive unit drives the side fork 71 to move forward and insert the side fork 71 into the slot of the new second-to-last pallet 2 in the pallet stack. Finally, the lifting drive unit drives the lifting frame 61 to move upward, and the lifting frame 61 drives the extension fork mechanism to move upward. The side fork 71 in the extension fork mechanism carries the pallet stack upward, leaving the new first-to-last pallet 2 on the belt conveyor 51.

[0118] S4. The second lifting drive lowers the height of the second lifting baffle, and the two second belt conveyors 51 continue to transport the new last pallet 2 backwards. After the new last pallet 2 leaves, the second lifting drive drives the second lifting baffle to rise and reset. This process continues until the required number of pallets 2 are unstacked.

[0119] S5. The pallet stacking shaping device of Example 1 flattens and aligns the four sides of the pallet stack.

[0120] Based on the working principle described above in Embodiment 3, it can be seen that Embodiment 3 has the following advantages:

[0121] By adding a shaping device to the pallet stacking and unstacking equipment, the neatness of the pallet stacks after stacking and unstacking can be improved, preventing misalignment and skewing of the pallet stacks and improving the stability of the pallet stacks.

[0122] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
