Description

Technical Field

[0001] This application relates to the technical field of product palletizing and lifting, and in particular to a palletizing and lifting machine. Background Technology

[0002] With the popularization of intelligent manufacturing, automated equipment has gradually replaced manual operation and become the mainstream in the manufacturing industry. Product palletizing is a very common production process. Therefore, palletizing lifting machines play an indispensable role, eliminating the need for traditional manual palletizing, saving time and labor, and enabling unmanned operation.

[0003] During the production process, products are placed in plastic boxes and conveyed on a conveyor belt. After the palletizing elevator picks up the plastic boxes, it stacks them. Therefore, the plastic boxes need to be moved horizontally to the stacking position, then moved down to place, and then moved up and horizontally again to complete one cycle. This makes the conveying time of the plastic boxes relatively long. At the same time, multiple clamping plates are generally used to hold the plastic boxes when picking them up. However, the surface of the plastic boxes is relatively smooth, and the weight of the products placed in the plastic boxes makes them relatively heavy, resulting in poor stability during the conveying process. Therefore, the conveying efficiency and operational stability of the palletizing elevator are urgent problems that need to be solved. Summary of the Invention

[0004] To improve the conveying efficiency and operational stability of palletizing elevators, this application provides a palletizing elevator.

[0005] This application provides a palletizing and lifting machine, which adopts the following technical solution:

[0006] A palletizing lifting machine includes a frame and a handling device, wherein the handling device includes:

[0007] A conveyor line is installed at the bottom of the frame and is used to place and transport the material boxes;

[0008] A transverse conveying device is installed on the top of the frame and plugged into both ends of the plastic box, and moves the plastic box along the direction of the conveyor line.

[0009] Two vertical conveying devices are located on both sides of the conveyor line and are spaced apart along the length of the plastic box. The two vertical conveying devices are inserted and installed on the opposite side walls of the plastic box and vertically convey the plastic box, enabling the plastic box to move between the conveyor line and the horizontal conveying device.

[0010] By adopting the above technical solution, the horizontal conveying device is inserted and installed on the plastic box, and the plastic box is transported between two vertical conveying devices. The two vertical conveying devices are activated and inserted into the plastic box. The horizontal conveying device is unlocked, and the two vertical conveying devices place the plastic box on the conveyor line. While placing the plastic box, the horizontal conveying device continues to transport the plastic box, so that multiple plastic boxes are stacked on the conveyor line. Then the conveyor line drives the stacked plastic boxes to move, which facilitates the subsequent placement of plastic boxes. At the same time, when transporting plastic boxes in the reverse direction, the stacked plastic boxes are placed on the conveyor line. The conveyor line is activated and drives the plastic boxes to move between the two vertical conveying devices. The two vertical conveying devices and the horizontal conveying device transport the plastic boxes in sequence to achieve the conveying.

[0011] By simultaneously activating the horizontal conveying device and two vertical conveying devices to move the plastic boxes, time is saved during the handling process. At the same time, the device is positioned by interlocking with the side wall of the plastic box during the conveying process, thereby improving the stability of the conveying process and enhancing the conveying efficiency and operational stability of the palletizing elevator.

[0012] Optionally, the lateral conveying device includes:

[0013] The movable block slides along the length of the plastic box and is positioned on the top of the frame.

[0014] Clamping block one and clamping block two are spaced apart along the sliding direction of the moving block. Clamping block one is slidably disposed on the moving block along the sliding direction of the moving block and is located between clamping block two and the frame. Clamping block two is rotatably mounted on the moving block.

[0015] A driving mechanism is used to drive the first clamping block to slide and the second clamping block to rotate, so that the first clamping block and the second clamping block are inserted and installed on both ends of the plastic box for positioning, or so that the first clamping block is located outside the plastic box and the second clamping block is located above the plastic box for unlocking the plastic box.

[0016] By adopting the above technical solution, the moving block drives clamping block one and clamping block two to approach the plastic box. The driving mechanism drives clamping block one to be inserted and installed on the plastic box. Then, the driving mechanism drives clamping block two to rotate and be inserted and installed on the plastic box, thereby being inserted and installed on both ends of the plastic box for positioning. The moving block drives the plastic box to approach the conveyor line, so that the plastic box moves between the two vertical conveying devices. The vertical conveying devices are inserted and installed on the opposite side walls of the plastic box for positioning. At this time, the two vertical conveying devices, clamping block one and clamping block two are respectively inserted and installed on the four side walls of the plastic box in different directions for positioning.

[0017] The drive mechanism drives the second clamp to rotate away from the plastic box and then rotates to above the plastic box. The first clamp moves away from the plastic box and disengages. The vertical conveying device moves down to place the plastic box on the conveyor line. The two vertical conveying devices release their clamps and move up to their original positions at the same time. Then, the next plastic box is conveyed, so that multiple plastic boxes are stacked vertically together. Then, the conveyor line drives the stacked plastic boxes to move.

[0018] The plastic box is conveyed by inserting clamps one and two into both ends, and two vertical conveying devices are inserted and installed on the other two side walls of the plastic box for positioning, which greatly improves the stability of the plastic box during transportation. The downward stacking and horizontal grabbing and conveying of the plastic box are carried out simultaneously, which greatly reduces the time spent on the plastic box and improves the conveying efficiency and operational stability of the palletizing elevator.

[0019] Simultaneously, by having clamp one move horizontally and be positioned on the side of the plastic box closer to the frame, while clamp two rotates and is positioned above the plastic box, the combination of these two motion methods, compared to moving or rotating alone, further improves the stability of the plastic box during transport. Furthermore, the fact that clamp two is positioned above the plastic box prevents it from colliding or interfering with the box during movement, making the operation more stable and further improving the conveying efficiency and operational stability of the palletizing elevator.

[0020] Optionally, the drive mechanism includes:

[0021] A movable frame is slidably mounted on the movable block along the sliding direction of the movable block, and the clamping block one is mounted on the movable frame and the clamping block two is rotatably mounted on the movable frame;

[0022] The push block is slidably mounted on the moving frame along the sliding direction of the moving block; the clamping block two is provided with a linkage hole;

[0023] A linkage column is mounted on the push block and slidably mounted on the linkage hole. The movement of the push block drives the second clamping block to rotate via the linkage column.

[0024] A pushing component is used to drive the moving frame and the pushing block to move. The moving frame moves and drives the first clamping block to approach and insert into the plastic box, so that the moving frame abuts against the moving block for positioning. The pushing block moves and drives the second clamping block to rotate and insert into the plastic box for positioning.

[0025] By adopting the above technical solution, the push component drives the moving frame, clamping block one, push block, and clamping block two to move simultaneously, so that the moving frame abuts against the moving block for positioning, preventing the moving frame from moving further. At the same time, clamping block one is inserted and installed on the side wall of the plastic box near the frame. The push component drives the push block to move relative to the moving frame. The movement of the push block drives the linkage column. The movement of the linkage column drives clamping block two to rotate downward. Clamping block two is inserted and installed on the side wall of the plastic box away from the frame for positioning, thereby realizing the clamping and conveying of the plastic box.

[0026] By pushing the block to move and driving the second clamping block to rotate, the plastic box is positioned against the second clamping block under the action of gravity. This not only positions the second clamping block under the action of gravity, but also greatly reduces the force on the pushing component during the clamping and conveying of the plastic box, thereby further improving the stability of the plastic box conveying process and increasing the conveying efficiency and operational stability of the palletizing elevator.

[0027] Simultaneously, by placing clamping block one on the movable frame, the sliding movement of the movable frame and the movable block allows clamping block one to move relative to the movable block, thereby increasing the connection area between the movable frame and the movable block, increasing the stability after the connection, and further improving operational stability.

[0028] Optionally, the pushing component includes:

[0029] Pusher component one and pusher component two are used to drive the moving frame and the pusher block to move, respectively.

[0030] By adopting the above technical solution, pusher one and pusher two drive the moving frame and pusher block to move respectively, thereby satisfying the driving effect of clamping block one and clamping block two according to different needs.

[0031] Optionally, the pushing component includes:

[0032] The push rod is slidably mounted on the movable frame and a push plate is provided at one end near the clamping block;

[0033] The elastic element is sleeved on the push rod and its two ends are connected to the push rod and the moving frame.

[0034] The push plate is mounted on the linkage rod and, under the elastic force of the elastic element, presses against the side wall of the moving frame away from the push plate for positioning.

[0035] The linkage rod is mounted on the push plate and connected to the push block;

[0036] Pushing component three is used to drive the push rod to move; the push rod drives the push disk to approach the moving frame and pushes the moving frame and clamping block one to approach and insert into the plastic box through the elastic element, so that the moving frame abuts against the moving block for positioning. The push rod continues to move to drive the push block to move and causes clamping block two to rotate and then insert into the plastic box for positioning.

[0037] By adopting the above technical solution, the three-pronged pusher drives the push rod, push plate, and push back plate to move closer to the moving block. The movement of the push plate drives the elastic element to squeeze the moving frame, causing the moving frame and clamping block one to move closer to the moving block until the moving frame abuts against the moving block for positioning. This allows clamping block one to be inserted into and positioned on the plastic box. The push rod and push plate continue to move, and the movement of the push rod drives the linkage rod and push block to move. The movement of the push block drives clamping block two to rotate, allowing clamping block two to be inserted into and positioned on the plastic box. At the same time, the movement of the linkage rod drives the push back plate away from the moving frame.

[0038] The third driving component drives the push rod, linkage rod, push plate, and return plate to move back. First, it drives the push block to move and rotate the clamping block two above the plastic box. Then, the linkage rod moves and drives the return plate to move back and abut against the moving frame for positioning. The third driving component continues to drive the return plate to move back, and the return plate pushes the moving frame back. This allows the clamping block one to move and the clamping block two to rotate in sequence. Compared to driving with two drive sources, driving with one drive source allows for more accurate control, is easier to maintain, and makes the clamping process more stable and faster, thus improving the conveying efficiency and operational stability of the palletizing elevator.

[0039] Meanwhile, the elastic element pushes the clamping block to be inserted into the plastic box. When the plastic box shifts and the clamping block cannot be properly inserted into the plastic box, the elastic block can provide buffering, reducing the risk of damage to the pushing component and improving the conveying efficiency and operational stability of the palletizing elevator.

[0040] Optionally, the vertical conveying device includes:

[0041] The movable seat is vertically slidable on the frame;

[0042] The clamping mechanism is set on the movable base. The two clamping mechanisms are inserted and installed on opposite side walls of the plastic box for positioning or to be detached from the plastic box to unlock.

[0043] The lifting mechanism is used to drive the moving seat to move vertically and place the plastic boxes onto the conveyor line for stacking and transport.

[0044] By adopting the above technical solution, the lateral conveying device transports the plastic box between two moving seats. The two clamping mechanisms are activated to position the plastic box on the opposite side walls of the plug-in mounting seat. The lifting mechanism drives the moving seats, clamping mechanisms and plastic box to move. After the movement is completed, the two clamping mechanisms move away from the plastic box to unlock, thereby driving the plastic box to move in the vertical direction.

[0045] Optionally, the clamping mechanism includes:

[0046] The finger is held in place and rotated on a movable base via a vertical pivot. The finger is inserted into a plastic box for positioning, or the finger can be rotated to the outside of the plastic box for unlocking.

[0047] The clamping element is mounted on the movable base;

[0048] A connecting rod is mounted on the clamping member and moves under the action of the clamping member. The connecting rod is connected to the clamping finger through a vertical rotating shaft and its movement drives the clamping finger to rotate.

[0049] The clamping finger has a first clearance hole and a first rotating shaft is slidably disposed on the first clearance hole, or the clamping finger has a second clearance hole and a second rotating shaft is disposed on the second clearance hole.

[0050] By adopting the above technical solution, the clamping component starts to drive the connecting rod to move, and the movement of the connecting rod drives the clamping finger to rotate, so that the clamping finger is inserted and installed on the opposite side walls of the plastic box for positioning, thereby achieving the positioning of the plastic box. When unlocking is required, the clamping component starts to drive the clamping finger to rotate to the outside of the plastic box, thereby achieving unlocking.

[0051] When the clamping fingers are inserted and installed on the plastic box, the position of the clamping fingers can be positioned under the action of gravity, that is, the state of the plastic box can be positioned under the action of gravity. The structure is simple and stable, and the speed is faster, which further improves the conveying efficiency and operational stability of the palletizing elevator.

[0052] Optionally, the lifting mechanism includes:

[0053] A timing belt is mounted on the frame and is vertically positioned and connected to the movable seat. Two timing belts are located on both sides of the conveyor line and are connected by a timing shaft.

[0054] A drive unit used to drive the synchronous belt to move.

[0055] By adopting the above technical solution, the driving component starts the movement of the synchronous belt connected to it, the movement of the synchronous belt drives the rotation of the synchronous shaft, and the rotation of the synchronous shaft drives the movement of another synchronous belt, thereby realizing the simultaneous movement of the two synchronous belts and the movement of the two synchronous belts driving the movement of the two moving seats.

[0056] Optionally, the clamping block is provided with two guide components, the guide components including:

[0057] The mounting plates are detachably mounted on the clamping block one. The two mounting plates abut against the side walls of the plastic box that are in contact with the clamping mechanism for positioning and cooperate to form a guide space that limits the movement of the plastic box.

[0058] The guide plate is rotatably mounted on the end of the mounting plate opposite to the clamping block.

[0059] A torsion member is mounted on the mounting plate and connected to the guide plate. Under the action of the torsion member, the two guide plates cooperate to form a figure-eight shape, and the distance between the ends away from the mounting plate is greater than the distance between the ends closer to the mounting plate. The clamping block drives the two guide plates to approach the plastic box and guides the plastic box so that the plastic box is aligned with the guide space and moves into the guide space, and the two guide plates and the two mounting plates are positioned against the side wall of the plastic box.

[0060] By adopting the above technical solution, the moving block drives clamping block one, two mounting plates, two guide plates, and two torque components to simultaneously approach the plastic box. The two guide plates have an eight-shaped opening to guide the plastic box. Then, clamping block one continues to drive the two guide plates to approach the plastic box, continuing to guide the plastic box until it is aligned with the guide space and moves into the guide space. The two mounting plates then abut against the plastic box for positioning. At the same time, the plastic box and the guide plates move relative to each other, driving the two guide plates to rotate and abut against the plastic box for positioning. This ensures that the distance between the plastic box and the two clamping mechanisms is the same, and the two clamping mechanisms insert and position the plastic box. This makes the force exerted by the plastic box on clamping block one, clamping block two, and the two clamping mechanisms more balanced, thereby further improving the stability during the conveying process and increasing the conveying efficiency and operational stability of the palletizing elevator.

[0061] At the same time, it also aligns the multiple plastic boxes after stacking, making the stacked plastic boxes more stable and further improving operational stability.

[0062] Optionally, a threaded sleeve is rotatably provided on the clamping block, and a threaded rod that is threadedly connected to the threaded sleeve is slidably provided on the clamping block. The two threaded rods are respectively connected to two mounting plates, and the rotation of the threaded sleeve drives the two mounting plates to move closer or further apart.

[0063] By adopting the above technical solution, the rotation of the threaded sleeve drives the two threaded rods to move simultaneously, thereby driving the two mounting plates to move closer or further apart, thus achieving the guiding and limiting of plastic boxes of different sizes and improving the adaptability.

[0064] In summary, this application includes at least one of the following beneficial technical effects:

[0065] 1. By simultaneously activating the horizontal conveying device and two vertical conveying devices to move the plastic boxes, time is saved during the handling process. At the same time, the device is positioned by interlocking with the side wall of the plastic box during the conveying process, thereby improving the stability of the conveying process and increasing the conveying efficiency and operational stability of the palletizing elevator.

[0066] 2. By having clamp one move horizontally and be positioned on the side of the plastic box closer to the frame, while clamp two rotates and is positioned above the plastic box, the combination of these two motion methods, compared to moving or rotating alone, further improves the stability of the plastic box during transport. Furthermore, the fact that clamp two is positioned above the plastic box prevents it from colliding or interfering with the box during movement, making the operation more stable and further improving the transport efficiency and operational stability of the palletizing elevator.

[0078] The following provides a further detailed description of this application.

[0079] This application discloses a palletizing and lifting machine.

[0080] Example 1, referring to Figure 1 The palletizing and lifting machine includes a frame 1 and a handling device 2 installed on the frame 1. Multiple frames 1 and handling devices 2 are installed at intervals and are connected to each other, so as to simultaneously grasp and transport different plastic boxes 12. The plastic boxes 12 can be filled with items or empty when transported. The four outer walls of the plastic boxes 12 are formed with grooves to facilitate manual or equipment grasping and transport.

[0081] Reference Figures 1-2 The handling equipment 2 includes a conveyor line 21, a horizontal handling device 3, and two vertical handling devices 6. The conveyor line 21 is set on the bottom of the frame 1 and is used to place and transport plastic boxes 12. The conveyor line 21 includes a mounting frame 22 and a conveyor belt 23. The mounting frame 22 and the frame 1 are parallel in length direction. The bottom of the mounting frame 22 is supported on the ground by multiple rollers. The multiple rollers are spaced apart along the length direction of the mounting frame 22. The mounting frame 22 is fixedly connected to the bottom of the frame 1 by screws. After the mounting frame 22 is separated from the frame 1, the conveyor line 21 can be moved to realize the replacement of the conveyor line 21.

[0082] The conveyor belt 23 is mounted on the mounting frame 22 and is in a horizontal position. The motor that drives the conveyor belt 23 to move is fixedly mounted on the mounting frame 22. Multiple plastic boxes 12 are placed on the conveyor belt 23 and are placed vertically to form a group. At the same time, multiple groups of plastic boxes 12 can be placed on the conveyor belt 23 along its own moving direction. The moving direction of the conveyor belt 23, the length direction of the plastic boxes 12 and the length direction of the mounting frame 22 are parallel to each other. The conveyor belt 23 drives the plastic boxes 12 to move. The conveyor belt 23 and the motor are existing structures and will not be described in detail here.

[0083] The transverse conveying device 3 is installed on the top of the frame 1 and is used to horizontally convey the plastic box 12 along the moving direction of the conveyor belt 23. The transverse conveying device 3 extends to the outside of the frame 1 to convey the plastic box 12 on the outside of the frame 1, or to transport and place the plastic box 12 on the outside of the frame 1.

[0084] Two vertical conveying devices 6 are used for vertically conveying plastic boxes 12 and are located on both sides of the conveyor line 21, and are spaced apart along the length perpendicular to the plastic box 12. The vertical conveying devices 6 are used to move the plastic boxes 12 between the conveyor line 21 and the horizontal conveying device 3, so that the plastic boxes 12 located on the horizontal conveying device 3 are placed and stacked on the conveyor belt 23, or so that multiple plastic boxes 12 stacked on the conveyor belt 23 are moved to the horizontal conveying device 3. The horizontal conveying device 3 transports the plastic boxes 12 to the conveying position. The horizontal conveying device 3 and the vertical conveying device 6 are both inserted and installed on the opposite side walls of the plastic box 12 for positioning during the transport.

[0085] Reference Figures 2-5 The transverse conveying device 3 includes a moving block 31, a clamping block 32 and a clamping block 33, and a drive mechanism 4. A moving component 11 is fixedly installed on the top of the frame 1. The moving component 11 can be a rodless cylinder or a rodless electric cylinder. The moving component 11 is arranged along the length of the frame 1, and one end of the moving component 11 extends to the outside of the frame 1 and the conveyor belt 23. The moving block 31 is fixedly installed on the moving component 11. The moving component 11 drives the moving block 31 to move, and the moving direction is along the length of the frame 1 and the plastic box 12. The clamping block 32 and the clamping block 33 are arranged at intervals along the sliding direction of the moving block 31. The clamping block 32 is located between the clamping block 33 and the frame 1. The clamping block 32 is slidably arranged on the moving block 31 along the sliding direction of the moving block 31. The clamping block 33 is rotatably installed on the moving block 31.

[0086] The drive mechanism 4 is used to drive the first clamp 32 to slide and the second clamp 33 to rotate, so that the first clamp 32 and the second clamp 33 are inserted and installed on both ends of the plastic box 12 for positioning, that is, the first clamp 32 and the second clamp 33 are inserted and supported on the top of the slot for positioning, so that the second clamp 33 can also be rotated when it is rotated out; or, the first clamp 32 is located outside the plastic box 12 and the second clamp 33 is located above the plastic box 12 for unlocking the plastic box 12.

[0087] The drive mechanism 4 includes a movable frame 41, a push block 42, a linkage column 43, and a push assembly 5. The movable frame 41 is slidably mounted on the movable block 31 via the sliding assembly 44. The movable frame 41 and the frame 1 are parallel in length direction. The sliding assembly 44 includes a sliding column 45 and a sliding plate 46. Two fixed blocks 47 are fixedly installed at intervals along the sliding direction of the movable block 31. There are two sliding columns 45, which are corresponding to the two fixed blocks 47. The sliding columns 45 slide through the fixed blocks 47 along the sliding direction of the movable block 31. The sliding plate 46 is U-shaped. The sliding plate 46 is fixedly mounted on both ends of the sliding column 45 and supported on the lower surface of the two fixed blocks 47 for positioning. The movable frame 41 is fixedly mounted on the lower surface of the sliding plate 46 at one end near the frame 1.

[0088] Push block 42 is slidably mounted on the end of the movable frame 41 away from the sliding plate 46 along the length direction of the movable frame 41. Linkage column 43 is fixedly mounted on the side wall of push block 42. Push assembly 5 is used to drive the movable frame 41 and push block 42 to move. Clamping block 1 32 is fixedly mounted on the end of the movable frame 41 near the frame 1. Clamping block 2 33 is rotatably mounted on the end of the movable frame 41 away from the frame 1. A strip-shaped linkage hole 34 is opened on clamping block 2 33. Linkage column 43 is slidably mounted on linkage hole 34, so that the movement of push block 42 drives clamping block 2 33 to rotate.

[0089] Clamping block 1 32 and clamping block 2 33 are identical in shape, both L-shaped, and arranged opposite each other. Both clamping blocks 1 32 and clamping block 2 33 have guide angles 35 for easy insertion, making it easy to insert and install clamping blocks 1 32 and clamping block 2 33 into the slot. At the same time, they push the plastic box 12 upward and abut against the lower surface of the moving frame 41 for positioning. The pushing component 5 first drives the moving frame 41, clamping block 1 32, pushing block 42, and clamping block 2 33 to move simultaneously. This is used to drive clamping block 1 32 to approach and insert into the plastic box 12, and to make the sliding plate 46 abut against the fixed block 47 for positioning. Then, it drives the pushing block 42 to move relative to the moving frame 41. The movement of the pushing block 42 drives clamping block 2 33 to rotate and insert into the plastic box 12 for positioning.

[0090] The pushing assembly 5 includes a first pushing member 51 and a second pushing member 52. The first pushing member 51 and the second pushing member 52 are identical and can be a cylinder or an electric push rod. The first pushing member 51 is fixedly installed on the moving block 31 or the fixed block 47. The piston rod of the first pushing member 51 is fixedly connected to the sliding plate 46 and is used to drive the sliding plate 46 to move. The second pushing member 52 is fixedly installed on the upper surface of the moving frame 41 away from the sliding plate 46. The pushing block 42 is fixedly installed on the piston rod of the second pushing member 52 and is used to realize the sliding installation of the pushing block 42 on the moving frame 41. The second pushing member 52 is activated to drive the pushing block 42 to move, thereby driving the first clamping block 32 to move and the second clamping block 33 to rotate.

[0091] Initially, clamping block 32 and sliding plate 46 tend to move away from moving block 31, and clamping block 33 is located above plastic box 12. Moving block 31 starts to drive moving frame 41, clamping block 32, pushing block 42 and clamping block 33 to move closer to the plastic box 12 to be transported. Then, pushing component 51 starts to drive clamping block 32, moving frame 41, pushing block 42 and clamping block 33 to continue to move, so that clamping block 32 approaches and is inserted into plastic box 12, and sliding plate 46 is positioned against fixed block 47. Pushing component 52 starts to drive clamping block 33 to rotate downward, so that clamping block 33 is inserted into plastic box 12, and plastic box 12 is positioned against the lower surface of moving frame 41. The moving block 31 starts the moving frame 41, clamping block 1 32 and clamping block 2 33, and the plastic box 12 all move back close to the frame 1, so that the plastic box 12 moves to the inside of the frame 1 and is located above the conveyor belt 23, thereby completing the horizontal transport of the plastic box 12.

[0092] Reference Figure 2 , Figures 6-7 The vertical conveying device 6 includes a movable seat 61, a clamping mechanism 7, and a lifting mechanism 62. The two movable seats 61 are located on both sides of the conveyor belt 23 and the plastic box 12 and are vertically slidably mounted on the frame 1. The two clamping mechanisms 7 are mounted on the two movable seats 61 and are simultaneously activated to insert and position themselves on the opposite side walls of the plastic box 12. The clamping mechanisms 7 are also inserted and positioned with the trough. Alternatively, the two clamping mechanisms 7 can be disengaged from the plastic box 12 to unlock it. The two clamping mechanisms 7, clamping block 1 32, and clamping block 2 33 cooperate to insert and position the side walls of the plastic box 12 in four different directions.

[0093] Multiple clamping mechanisms 7 located on the same movable seat 61 are also spaced apart along the sliding direction of the movable block 31. The clamping mechanism 7 includes a clamping finger 71, a clamping member 72, and a connecting rod 73. The clamping finger 71 is rotated and mounted on the movable seat 61 via a vertical pivot. When the clamping finger 71 is rotated to the inside of the two movable seats 61, it can be inserted and mounted on the plastic box 12 for positioning. Alternatively, when the clamping finger 71 is rotated to the outside of the two movable seats 61, the plastic box 12 can be unlocked.

[0094] The clamping component 72 is fixedly installed on the side wall of the movable seat 61 away from the conveyor line 21. The clamping component 72 can be a cylinder or an electric push rod. The piston rod of the clamping component 72 is set along the length of the plastic box 12. The connecting rod 73 is fixedly installed on the piston rod of the clamping component 72. The connecting rod 73 is rotatably connected to the clamping finger 71 through a vertical rotating shaft 2. At the same time, the rotating shaft 2 is located on the side of the rotating shaft 1 away from the conveyor line 21.

[0095] The piston rod of the clamping member 72 moves to drive the clamping finger 71 to rotate. In order to enable the connecting rod 73 to move horizontally to drive the clamping finger 71 to rotate, a first clearance hole is provided on the clamping finger 71 at a point on the rotating shaft, and the first rotating shaft is slidably connected to the first clearance hole; or, a second clearance hole is provided on the clamping finger 71 at a second point on the rotating shaft, and the second rotating shaft is slidably connected to the second clearance hole, so that it can make way when the clamping finger 71 is driven to rotate horizontally.

[0096] The lifting mechanism 62 is used to drive the two movable seats 61 to move vertically simultaneously, and to place the plastic box 12 on the conveyor line 21 for stacking and conveying. The lifting mechanism 62 includes two synchronous belts 63 and a drive component 64. The two synchronous belts 63 are installed on the top and bottom of the frame 1 and are correspondingly arranged and connected to the two movable seats 61. The synchronous belt 63 includes two pulleys and a belt body. The two pulleys are rotatably installed on the top and bottom of the frame 1, respectively. The belt body is sleeved on the two pulleys and connected to the movable seats 61. The two pulleys located at the top of the frame 1 are connected by a synchronous shaft 65, so that the two synchronous belts 63 move simultaneously. The drive component 64 is a servo motor. The drive component 64 is fixedly installed on the top of the frame 1, and the output shaft of the drive component 64 is connected to one of the pulleys, thereby realizing the simultaneous movement of the two synchronous belts 63.

[0097] Reference Figures 2-7 The moving block 31 drives the plastic box 12 to move above the conveyor line 21. The two moving seats 61 move upwards simultaneously. The two clamping mechanisms 7 are activated and inserted into the opposite side walls of the plastic box 12 for positioning. The first clamping block 32 moves away from the plastic box 12, and the second clamping block 33 rotates away from the plastic box 12 to unlock the plastic box 12. The two moving seats 61 move downwards to place the plastic box 12 onto the conveyor belt 23. The two clamping mechanisms 7 release the insertion and positioning of the plastic box 12. At the same time, the moving block 31 moves to continue conveying the plastic box 12 above the conveyor line 21. The two moving seats 61 and the clamping mechanisms 7 continue to convey the plastic box 12 to place the previous plastic box 12, thereby stacking multiple plastic boxes 12. Then the conveyor belt 23 is activated to drive multiple plastic boxes 12 to move forward to make way for subsequent plastic boxes 12. Then, multiple plastic boxes 12 are placed repeatedly.

[0098] Meanwhile, when it is necessary to place the empty plastic box 12 in another position, the empty plastic box 12 is stacked on the conveyor belt 23. The conveyor belt 23 drives the plastic box 12 to move between the two moving seats 61. The two moving seats 61 and the clamping mechanism 7 clamp the highest plastic box 12 and move it upward. Then, the clamping block 1 32 and clamping block 2 33 are inserted and positioned. The two clamping mechanisms 7 are released and positioned. The moving block 31 moves and drives the plastic box 12 to be transported to the placement position and placed. Then the moving block 31 moves back and repeats the process, so that the empty plastic box 12 can be placed at the conveying position.

[0099] The working principle of this application embodiment is as follows:

[0100] The moving block 31 initiates the movement of the frame 41, clamping block 32, and clamping block 33, all of which move closer to the plastic box 12 to be transported. The pushing component 51 initiates the movement of clamping block 32, which then moves closer to and inserts into the plastic box 12. The sliding plate 46 abuts against the fixed block 47 for positioning. The pushing component 52 initiates the rotation of clamping block 33, which then inserts into the plastic box 12, positioning it against the lower surface of the moving frame 41. The moving block 31 then initiates the movement of clamping blocks 32, 33, and the plastic box 12 back towards the frame 1, moving the plastic box 12 to the inside of the frame 1 and above the conveyor belt 23.

[0101] Two movable seats 61 move upwards simultaneously, and two clamping mechanisms 7 are activated and inserted into the opposite side walls of the plastic box 12 for positioning. Clamping blocks 1 32 and 2 33 move away from the plastic box 12. The two movable seats 61 move downwards to place the plastic box 12 onto the conveyor belt 23. The two clamping mechanisms 7 release the insertion and positioning of the plastic box 12. At the same time, the movable block 31 moves to continue conveying the plastic box 12 above the conveyor line 21. The two movable seats 61 and the clamping mechanisms 7 continue to convey the plastic box 12 to place the previous plastic box 12, thereby stacking multiple plastic boxes 12. Then the conveyor belt 23 starts to drive multiple plastic boxes 12 forward to make way for subsequent plastic boxes 12. Then, multiple plastic boxes 12 are placed repeatedly, which improves the conveying efficiency and operational stability of the palletizing elevator.

[0102] Example 2, refer to Figures 2-3 , Figure 8 The difference between this embodiment and embodiment 1 is that the pushing assembly 5 includes a pushing rod 53, an elastic element 54, a push plate 55, a linkage rod 56, and a pushing element 57. The sliding plate 46 near the clamping block 32 is a sliding part 13. The pushing rod 53 slides along the sliding direction of the moving block 31 and passes through the sliding part 13. A pushing disk 58 is fixedly installed on one end of the pushing rod 53 near the clamping block 32. The pushing disk 58 is located on the side of the sliding part 13 near the frame 1. The elastic element 54 is a spring. The elastic element 54 is sleeved on the pushing rod 53 and its two ends press against the pushing disk 58 and the sliding part 13. The push plate 55 is fixedly installed on the pushing rod 53 and is located on the side of the sliding part 13 away from the clamping block 32 and the frame 1.

[0103] In the initial state, the push plate 55 is positioned by pressing against the side wall of the sliding part 13 away from the elastic member 54 under the elastic force of the elastic member 54. The linkage rod 56 is fixedly installed on the push plate 55 and is connected to the push block 42. The push member 57 is an electric push rod or a cylinder. The push member 57 is fixedly installed on the moving block 31 and the piston rod is connected to the linkage rod 56.

[0104] When the plastic box 12 needs to be inserted and positioned, the pusher 3 57 activates the drive linkage 56 and the pusher 58 to move closer to the moving block 31. The movement of the pusher 58 drives the pusher plate 55, the linkage 56 and the pusher 42 to move. At the same time, the movement of the pusher 58 causes the elastic member 54 to press the sliding part 13, the moving frame 41 and the clamping block 32 to move, so that the moving frame 41 and the pusher 42 move at the same time, so that the clamping block 32 moves closer and is inserted and installed on the plastic box 12 for positioning. At the same time, the sliding part 13 abuts against the moving frame 41 for positioning, so that the moving frame 41 is positioned and cannot continue to move.

[0105] Pushing component 3 57 pushes linkage rod 56 to continue moving, pushing disc 58 squeezes elastic element 54, linkage rod 56 pushes back push plate 55 away from sliding part 13 and drives push block 42 to move relative to moving frame 41 through linkage rod 56, so that clamping block 2 33 rotates and is inserted into plastic box 12 for positioning; when unlocking is required, pushing component 3 57 drives linkage rod 56, back push plate 55 and push block 42 to move back, so that clamping block 2 33 rotates away from plastic box 12, back push plate 55 abuts against sliding part 13, pushes sliding part 13, moving frame 41 and clamping block 1 32 to move back away from plastic box 12, thereby unlocking plastic box 12.

[0106] The device can first insert and install clamping block 32 onto one end of plastic box 12 according to requirements, and then insert and install clamping block 33 onto the other end of plastic box 12 for positioning. This reduces the risk of sequence disorder when using two drive sources and improves the stability of operation. At the same time, the elastic element 54 drives clamping block 32 to insert and install into plastic box 12. When an obstruction is encountered during the insertion process, it can buffer the situation, reduce the risk of damage to the drive source due to force, and improve the conveying efficiency and the stability of operation.

[0107] The working principle of this application embodiment is as follows:

[0108] The third pusher 57 initiates movement of the moving frame 41 and clamping block 32 via the elastic element 54, causing clamping block 32 to approach and be inserted into the plastic box 12 for positioning. Simultaneously, the sliding part 13 abuts against the moving frame 41 for positioning. The third pusher 57 drives clamping block 33 to rotate and then inserts into the plastic box 12 for positioning. When unlocking is required, the third pusher 57 drives clamping block 33 to rotate away from the plastic box 12, and the pusher plate 55 moves back to push clamping block 32 back away from the plastic box 12, thereby unlocking the plastic box 12. This reduces the risk of sequence disorder when using two drive sources, and also reduces the risk of damage to the drive sources due to force, improving conveying efficiency and operational stability.

[0109] Example 3, referring to Figures 2-3 , Figures 9-10The difference between this embodiment and embodiment 1 is that two guide components 8 are provided on clamping block 32. The two guide components 8 are spaced apart along the length direction perpendicular to the plastic box 12 and are mirror-symmetrical about the plastic box 12. The two guide components 8 cooperate to align the plastic box 12. After clamping block 32 and clamping block 33 are inserted and installed on the plastic box 12, the distance between the plastic box 12 and the two clamping mechanisms 7 is the same. The two clamping mechanisms 7 are inserted and installed on the plastic box 12, so that the force exerted by the plastic box 12 on clamping block 32, clamping block 33 and the two clamping mechanisms 7 is more balanced, which further improves the stability during operation and improves the conveying efficiency.

[0110] A threaded sleeve 83 is rotatably installed on the side wall of clamping block 32 near the frame 1. Two threaded rods 84 are slidably installed on the side wall of clamping block 32 and are threaded to both ends of the threaded sleeve 83. The two threaded rods 84 are arranged symmetrically about the plastic box 12. The rotation of the threaded sleeve 83 can drive the two threaded rods 84 to move closer or further apart.

[0111] The guide assembly 8 includes a mounting plate 81, a guide plate 82, and a torque member. A threaded rod 84 is fixedly mounted on the mounting plate 81. The end of the mounting plate 81 away from the threaded rod 84 extends along the length of the plastic box 12 to the side of the clamping block 32 away from the frame 1. The two mounting plates 81 cooperate to form a guide space 85 that limits the plastic box 12. After the plastic box 12 is moved onto the guide space 85, the two mounting plates 81 abut against the opposite side walls of the plastic box 12 that are in contact with the clamping mechanism 7 for positioning, so that the clamping block 32 and the clamping block 33 are located at the center of the plastic box 12.

[0112] One end of the guide plate 82 is rotatably mounted on the end of the mounting plate 81 away from the threaded rod 84 via a rotating column 86. The torque element is sleeved on the rotating column 86 and connected to the mounting plate 81 and the guide plate 82. In the initial state, the two guide plates 82 cooperate to form a figure-eight structure, so that the distance between the ends of the two guide plates 82 away from the mounting plate 81 is greater than the distance between the ends closer to the mounting plate 81, thereby guiding the plastic box 12 and pushing the plastic box 12 to align with the guide space 85, so that the plastic box 12 moves onto the guide space 85. When the plastic box 12 enters, it pushes the two guide plates 82 to rotate, so that the mounting plate 81 and the guide plate 82 both press against the side wall of the plastic box 12 for positioning. After the plastic box 12 moves out of the guide space 85, the two guide plates 82 rotate under the action of the torque element, and then can continue to guide the next plastic box 12.

[0113] The working principle of this application embodiment is as follows:

[0114] The moving block 31 drives the moving frame 41, clamping block 32, and two guide components 8 to approach the plastic box 12. The plastic box 12 first contacts the two guide plates 82 for guidance. Then, clamping block 32 continues to drive the two guide plates 82 to approach the plastic box 12, so that the plastic box 12 is aligned with the guide space 85 and moves into the guide space 85. This allows the two mounting plates 81 and the two guide plates 82 to press against the plastic box 12 for positioning. Clamping block 32 moves away from the plastic box 12, so that the plastic box 12 moves out of the guide space 85. The two guide plates 82 rotate under the action of the torsion member, which facilitates the continued guidance of the plastic box 12. This makes the plastic box 12 more stable during transportation, improving the transportation efficiency and the stability of operation.

[0115] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
