Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable sorting technology, and in particular to a tray separation device and a fruit and vegetable sorting machine. Background Technology

[0002] As people pursue a higher quality of life, more and more people are demanding higher quality fruits and vegetables, making fruit and vegetable sorting an important technology. Fruit and vegetable sorting involves packing the fruits and vegetables into boxes. Each box may need to contain trays to separate the fruits and vegetables between layers. During sorting, multiple trays are stacked together. During packing, the trays need to be separated one by one and placed into the fruit boxes sequentially.

[0003] Currently, when separating stacked pallets, the common method is to pick up or grab the pallets from below to achieve separation and transfer. However, due to the weight of the pallets themselves, the pallet grabbing process can easily cause other pallets to fall or shift, resulting in unstable pallet separation. Utility Model Content

[0004] The present invention aims to provide a tray separation device and a fruit and vegetable sorting machine to solve the technical problem of unstable tray separation in the prior art.

[0005] The technical problem solved by this utility model embodiment is addressed by the following technical solution: One embodiment of the present invention provides a pallet separation device, including a main frame, a first lifting component, a second lifting component, a gripping component, and a conveying component; The first lifting component, the second lifting component, the gripping component, and the conveying component are mounted on the main frame; The first lifting component, the second lifting component, and the conveying component are located below the gripping component. The first lifting component and the second lifting component are used to hold and lift the pallet, and the gripping component is used to transfer the pallet located on the first lifting component or the second lifting component to the conveying component.

[0006] In the pallet separation device of this embodiment, the main frame is used to mount the first lifting component, the second lifting component, the gripping component, and the conveying component. Stacked pallets can be placed on both the first and second lifting components, which can lift the stacked pallets to the same height as the conveying component. Since the first, second, and conveying components are all located below the gripping component, the gripping component can grip the topmost pallet from above the first and second lifting components and transfer it to the conveying component. Because the gripping component grips the pallet from above the first and second lifting components, the remaining pallets will not fall or shift due to their own weight during the gripping process, thus avoiding unstable pallet separation. Furthermore, both the first and second lifting components can hold pallets, and the types and positions of the pallets held on the first and second lifting components can be the same or different, adapting to various operational requirements and application scenarios.

[0007] In one embodiment, the tray separation device further includes a controller, a first sensing component, and a second sensing component; The first lifting component and the second lifting component are used to lift the pallet to a first preset height position or a second preset height position, wherein the first preset height position is higher than the second preset height position, and the gripping component is used to transfer the pallet located at the first preset height position to the conveying component; The first sensing component and the second sensing component are disposed on the main frame. The first sensing component is used to sense the first preset height position of the tray, and the second sensing component is used to sense the second preset height position of the tray. The controller is communicatively connected to the first sensing component, the second sensing component, the first lifting component, the second lifting component, and the grasping component.

[0008] In this embodiment, under the unified control of the controller, when the first lifting component lifts the multiple stacked pallets and the top pallet reaches a first preset height position, the first sensing component is triggered. After the gripping component grips the top pallet, the lifting component moves the remaining pallets down to a second preset height position. When the pallets reach the second preset height position, the second sensing component is triggered. Simultaneously, the gripping component transfers the gripped pallet to the conveying component, which then transports it to the downstream workstation. Then, the second lifting component moves upward and repeats the same steps as the first lifting component, allowing the gripping component to transfer the top pallet of the second lifting component to the conveying component. By setting the first and second lifting components, the gripping component can alternately transfer the top pallets of the first and second lifting components to the conveying component. When repeating the above steps, all pallets stacked on the first and second lifting components can be transferred to the conveying component. The pallet separation device of this embodiment can adapt to multiple types and positions of pallets. Moreover, under the unified control of the controller, the pallet separation device of this embodiment has a high degree of automation and can realize assembly line operation.

[0009] In one embodiment, the first lifting component includes a first lifting mechanism and a first support plate. The first lifting mechanism and the first support plate are connected in a transmission manner to drive the first support plate to lift. The top surface of the first support plate is provided with a first holding station, which is used to hold the tray. The second lifting assembly includes a second lifting mechanism and a second support plate. The second lifting mechanism and the second support plate are connected by a transmission to drive the second support plate to lift. The top surface of the second support plate is provided with a second holding station, which is used to hold the tray.

[0010] In this embodiment, stacked pallets can be placed at a first holding station and a second holding station. A first lifting mechanism raises and lowers a first support plate, allowing the pallet at the first holding station to reach a first preset height position or a second preset height position. A second lifting mechanism raises and lowers a second support plate, allowing the pallet at the second holding station to reach either the first preset height position or the second preset height position.

[0011] In one embodiment, the first lifting component further includes at least two first guide posts. The first support plate has first through holes. The number of first through holes is equal to the number of first guide posts and they correspond one-to-one. Each first through hole is arranged around the first holding station. Each first guide post is vertically arranged on the main frame and passes through the corresponding first through hole. The second lifting component also includes at least two second guide posts. The second support plate has a second through hole. The number of the second through holes is equal to the number of the second guide posts and they correspond one-to-one. Each second through hole is arranged around the second holding station. Each second guide post is vertically arranged on the main frame and passes through the corresponding second through hole.

[0012] In this embodiment, each first guide post is arranged around the first holding station, thus limiting the position of the tray placed at the first holding station and preventing the tray from shifting, ensuring that the gripping component can accurately grip the tray. Secondly, due to the cooperation between the first guide post and the corresponding first through hole, the installation position of the first support plate is limited, thereby ensuring that the position of the first holding station on the first support plate is relatively accurate, and thus ensuring that the gripping component can accurately grip the tray. In addition, when the first lifting mechanism drives the first support plate to rise and fall, the first guide post and the corresponding first through hole cooperate with each other, thereby guiding the movement of the first support plate in the vertical direction.

[0013] Each second guide post is positioned around the second holding station, thus limiting the position of the pallet placed there and preventing it from shifting, ensuring the gripping component can accurately grasp the pallet. Secondly, the cooperation between the second guide posts and their corresponding second through holes limits the installation position of the second support plate, ensuring the accurate positioning of the second holding station on the second support plate, and consequently, ensuring the gripping component can accurately grasp the pallet. Furthermore, when the second lifting mechanism drives the second support plate to rise or fall, the second guide posts and their corresponding second through holes cooperate to guide the vertical movement of the second support plate.

[0014] In one embodiment, the first through hole includes a first strip-shaped through hole and a first strip-shaped notch. The first strip-shaped through hole is respectively opened at one opposite end of the first support plate, and the first strip-shaped notch is respectively opened at the other opposite end of the first support plate. The first guide post is respectively inserted into each first strip-shaped through hole and each first strip-shaped notch. The first strip-shaped through hole is arranged along a first direction, and the first strip-shaped notch is arranged along a second direction. The first direction and the second direction are perpendicular. Each of the first strip-shaped through holes and each of the first strip-shaped notches are arranged around the first holding station; The second through hole includes a second strip-shaped through hole and a second strip-shaped notch. The second support plate has the second strip-shaped through hole opened at one opposite end and the second strip-shaped notch opened at the other opposite end. The second guide post is inserted into each second strip-shaped through hole and each second strip-shaped notch. The second strip-shaped through hole is arranged along the first direction and the second strip-shaped notch is arranged along the second direction. Each of the second strip-shaped through holes and each of the second strip-shaped notches are arranged around the second holding station.

[0015] In this embodiment, by providing a first strip-shaped through hole, the position of the corresponding first guide post relative to the first support plate can be adjusted along the first direction during installation. The first support plate has a large degree of freedom along the first direction, thus facilitating installation. Furthermore, adjusting the corresponding first guide post also allows adjustment of the dimension of the first holding station along the first direction. By providing a first strip-shaped notch, the position of the corresponding first guide post relative to the first support plate can also be adjusted along the second direction during installation. The first support plate has a large degree of freedom along the second direction, thus facilitating installation. Furthermore, adjusting the corresponding first guide post also allows adjustment of the dimension of the first holding station along the second direction, thus enabling the first holding station to accommodate trays of different sizes. Additionally, after installing the first guide post, the first strip-shaped through holes of the first support plate can be inserted through the corresponding first guide post, and then the first strip-shaped notches of the first support plate can be fitted onto the corresponding first guide post, thus further improving installation convenience.

[0016] By providing a second strip-shaped through-hole, the position of the corresponding second guide post relative to the second support plate can be adjusted along the first direction during installation. The second support plate has a large degree of freedom along the first direction, thus facilitating installation. Furthermore, adjusting the corresponding second guide post also allows adjustment of the dimensions of the second holding station along the first direction. By providing a second strip-shaped notch, the position of the corresponding second guide post relative to the second support plate can also be adjusted along the second direction during installation. The second support plate has a large degree of freedom along the second direction, thus facilitating installation. Furthermore, adjusting the corresponding second guide post also allows adjustment of the dimensions of the second holding station along the second direction, enabling the second holding station to accommodate trays of different sizes. Additionally, after installing the second guide post, the second strip-shaped through-holes of the second support plate can be inserted through the corresponding second guide post, and then the second strip-shaped notches of the second support plate can be fitted onto the corresponding second guide post, thus further improving installation convenience.

[0017] In one embodiment, the top of each of the first guide posts is inclined in a direction away from the first holding station, so that a first guide opening is formed between each of the first guide posts; The top of each of the second guide posts is tilted away from the second holding station so that a second guide opening is formed between each of the second guide posts.

[0018] In this embodiment, the first guide port serves a guiding function, enabling stacked pallets to be smoothly placed into the first holding station. The second guide port also serves a guiding function, enabling stacked pallets to be smoothly placed into the second holding station.

[0019] In one embodiment, the gripping component includes a lateral movement mechanism, a telescopic drive mechanism, and a needle. The lateral movement mechanism is mounted on the main frame, and the first lifting component, the second lifting component, and the conveying component are located below the lateral movement mechanism; The telescopic drive mechanism includes a fixed end and a telescopic end. The fixed end is disposed on the lateral movement mechanism, and the telescopic end is located below the fixed end. The needle is disposed on the telescopic end.

[0020] In this embodiment, the above structure enables the trays of the first lifting component and the second lifting component to be transferred to the conveying component quickly and accurately.

[0021] In one embodiment, there are two telescopic drive mechanisms, which are inclined relative to the horizontal plane. The fixed ends of the two telescopic drive mechanisms are close to each other, while the telescopic ends are far apart from each other. The two telescopic ends are respectively provided with the needles.

[0022] In this embodiment, the telescopic ends also extend or retract at an angle. Therefore, the telescopic ends can also tilt to drive the needles to pierce the tray. When the two needles on the two telescopic ends pierce into a tray respectively, the two needles can form a stronger connecting force on the tray, which can prevent the tray from falling off during the transfer to the conveyor assembly. In addition, since the needles on the two telescopic ends pierce the tray at an angle, when the telescopic ends drive the needles to retract, the component force of the connecting force of each needle on the tray changes significantly, making it easier for the needles to exit from the tray. Each telescopic end can be equipped with multiple needles, and the multiple needles located on the same telescopic end are parallel to each other, facilitating smooth piercing into the tray.

[0023] In one embodiment, the gripping component further includes two adjustment mechanisms disposed on the lateral movement mechanism. Each adjustment mechanism is tractively connected to a corresponding fixed end to adjust the distance between the two fixed ends.

[0024] In this embodiment, by adjusting the distance between the two fixed ends, the needle can grip trays of different sizes.

[0025] Another embodiment of this utility model provides a fruit and vegetable sorting machine, including the tray separation device in any of the above embodiments.

[0026] Compared with existing technologies, in the pallet separation device of this utility model, the main frame is used to install the first lifting component, the second lifting component, the gripping component, and the conveying component. Stacked pallets can be placed on both the first and second lifting components, which can lift the stacked pallets to the same height as the conveying component. Since the first, second, and conveying components are all located below the gripping component, the gripping component can grip the topmost pallet from above the first and second lifting components and transfer it to the conveying component. Because the gripping component grips the pallet from above the first and second lifting components, the remaining pallets will not fall or shift due to their own weight during the gripping process, thus avoiding unstable pallet separation. Furthermore, both the first and second lifting components can hold pallets, and the types and positions of the pallets held on the first and second lifting components can be the same or different, adapting to various operational requirements and application scenarios.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0032] The following detailed description, in conjunction with all the accompanying drawings, of a tray separation device 100 and a fruit and vegetable sorting machine provided in this application, will be provided through specific embodiments.

[0033] Please refer to Figure 1One embodiment of this utility model discloses a pallet separation device 100, including a main frame 10, a first lifting component 20, a second lifting component 30, a gripping component 40, and a conveying component 50; The first lifting component 20, the second lifting component 30, the gripping component 40, and the conveying component 50 are mounted on the main frame 10; The first lifting component 20, the second lifting component 30, and the conveying component 50 are located below the gripping component 40. The first lifting component 20 and the second lifting component 30 are used to hold and lift the pallet 101, and the gripping component 40 is used to transfer the pallet 101 to the conveying component 50.

[0034] In the pallet separation device 100 of this embodiment, the main frame 10 is used to mount the first lifting component 20, the second lifting component 30, the gripping component 40, and the conveying component 50. Stacked pallets 101 can be placed on both the first lifting component 20 and the second lifting component 30, and the first lifting component 20 and the second lifting component 30 can lift the stacked pallets 101 to a position equal to the height of the conveying component 50. Since the first lifting component 20, the second lifting component 30, and the conveying component 50 are all located below the gripping component 40, the gripping component 40 can grip the topmost pallet 101 from above the first lifting component 20 and the second lifting component 30 and transfer the pallet 101 to the conveying component 50. Because the gripping component 40 grips the pallet 101 from above the first lifting component 20 and the second lifting component 30, the remaining pallets 101 will not fall or shift due to their own weight during the gripping process, thus avoiding unstable separation of the pallets 101. In addition, both the first lifting component 20 and the second lifting component 30 can hold the tray 101. The type and position of the tray 101 held on the first lifting component 20 and the second lifting component 30 can be the same or different, which can adapt to various operation requirements and application scenarios.

[0035] In one specific embodiment, the tray 101 includes end A and end B. End A of the tray 101 can hold three fruits and vegetables, and end B can hold two fruits and vegetables. The stacked trays 101 are staggered. For example, the bottom tray 101 has end A on the left and end B on the right, while the trays 101 above it have end A on the right and end B on the left, and so on. When the types of trays 101 on the first lifting component 20 and the second lifting component 30 are the same, the stacked trays 101 on each of the first lifting component 20 and the second lifting component 30 are staggered. Therefore, on the same horizontal plane, the trays 101 on the first lifting component 20 and the trays 101 on the second lifting component 30 are symmetrically placed, that is, their positions are different. However, the gripping component 40 can transfer the pallet 101 on the first lifting component 20 and the pallet 101 on the second lifting component 30 to the conveying component 50 respectively, without being affected by the type and position of the pallet 101. Therefore, it can adapt to multiple types and positions of the pallet 101 and meet multiple operational needs.

[0036] It is understood that multiple pallets 101 stacked on the first conveying component 50, the first lifting component 20, and the second lifting component 30 can be conveyed, but a single pallet 101 can also be conveyed in the same way.

[0037] Please refer to the above as well. Figure 2 and Figure 3 In one embodiment, the tray separation device 100 further includes a controller, a first sensing component 60, and a second sensing component 70; The first lifting component 20 and the second lifting component 30 are used to lift the pallet 101 to a first preset height position or a second preset height position, where the first preset height position is higher than the second preset height position. The gripping component 40 is used to transfer the pallet 101 located at the first preset height position to the conveying component 50. The first sensing component 60 and the second sensing component 70 are disposed on the main frame 10. The first sensing component 60 is used to sense the first preset height position of the tray 101, and the second sensing component 70 is used to sense the second preset height position of the tray 101. The controller is communicatively connected to the first sensing component 60, the second sensing component 70, the first lifting component 20, the second lifting component 30, and the grasping component 40.

[0038] In this embodiment, under the unified control of the controller, when the first lifting component 20 lifts the multiple stacked pallets 101 and the top pallet 101 reaches a first preset height position, the first sensing component 60 is triggered. After the gripping component 40 grips the top pallet 101, the first lifting component 20 moves the remaining pallets 101 down to a second preset height position. When the pallets 101 move down to the second preset height position, the second sensing component 70 is triggered. At the same time, the gripping component 40 transfers the gripped pallet 101 to the conveying component 50, and the conveying component 50 transports the pallet 101 to the downstream workstation. Then, the second lifting component 30 moves upward and repeats the same steps as the first lifting component 20, so that the gripping component 40 transfers the top pallet 101 of the second lifting component 30 to the conveying component 50. By setting up a first lifting component 20 and a second lifting component 30, the gripping component 40 can alternately transfer the uppermost pallets 101 of the first lifting component 20 and the second lifting component 30 to the conveying component 50. When the above steps are repeated, all pallets 101 stacked on the first lifting component 20 and the second lifting component 30 can be transferred to the conveying component 50. The pallet separation device 100 of this embodiment can adapt to multiple types and positions of pallets 101. Moreover, under the unified control of the controller, the pallet separation device 100 of this embodiment has a high degree of automation and can realize assembly line operation.

[0039] In one specific embodiment, the controller can be a PLC controller. The first sensing component 60 includes two first photoelectric switches, which are respectively configured to correspond to the first lifting component 20 and the second lifting component 30, and are used to detect the first preset height position of the tray 101 on the first lifting component 20 and the second lifting component 30. The second sensing component 70 includes two second photoelectric switches, which are respectively configured to correspond to the first lifting component 20 and the second lifting component 30, and are used to detect the second preset height position of the tray 101 on the first lifting component 20 and the second lifting component 30. The first sensing component 60 and the second sensing component 70 are respectively mounted on the main frame 10. The controller and the first sensing component 60, the second sensing component 70, the first lifting component 20, the second lifting component 30, and the gripping component 40 can be connected electrically, via wired communication, or via wireless communication to achieve unified and coordinated control.

[0040] In one embodiment, the first lifting assembly 20 includes a first lifting mechanism 22 and a first support plate 24. The first lifting mechanism 22 and the first support plate 24 are connected by a transmission to drive the first support plate 24 to lift. The top surface of the first support plate 24 is provided with a first holding station 242, which is used to hold the tray 101. The second lifting assembly 30 includes a second lifting mechanism 32 and a second support plate 34. The second lifting mechanism 32 and the second support plate 34 are connected by a transmission to drive the second support plate 34 to lift. The top surface of the second support plate 34 is provided with a second holding station 342, which is used to hold the tray 101.

[0041] In this embodiment, stacked pallets 101 can be placed at the first holding station 242 and the second holding station 342. The first lifting mechanism 22 drives the first support plate 24 to rise and fall, allowing the pallet 101 at the first holding station 242 to reach either a first preset height position or a second preset height position. The second lifting mechanism 32 drives the second support plate 34 to rise and fall, allowing the pallet 101 at the second holding station 342 to reach either a first preset height position or a second preset height position.

[0042] In one specific embodiment, the first lifting mechanism 22 includes a first lead screw mechanism, which includes a first lead screw 222, a first lead screw nut 224, a first lead screw seat 226, a first motor 228, and slide rail modules 229. The first lead screw seat 226 is mounted on the main frame 10. The first lead screw 222 is rotatably mounted on the first lead screw seat 226 and is vertically arranged. The first motor 228 is connected to the first lead screw 222 to drive the first lead screw 222 to rotate. The first lead screw nut 224 is sleeved on the first lead screw 222 and is connected to the first support plate 24. After the first lead screw 222 rotates, the first lead screw nut 224 can move along the axial direction of the first lead screw 222, thereby driving the first support plate 24 to move up and down. There are four slide rail modules 229, and each slide rail module 229 is located at one of the four corners of the first support plate 24. Each slide rail module 229 includes a slide rail 2292 and a slider 2294. The slide rail 2292 is mounted on the main frame 10 and is vertically arranged. The slider 2294 is slidably arranged on the slide rail 2292 and is connected to the first support plate 24.

[0043] In one specific embodiment, the structure of the second lifting mechanism 32 is the same as that of the first lifting mechanism 22, and will not be described in detail here.

[0044] In one embodiment, the first lifting component 20 further includes at least two first guide posts 26, and the first support plate 24 is provided with first through holes 244. The number of first through holes 244 is equal to the number of first guide posts 26 and corresponds one-to-one. Each first through hole 244 is arranged around the first holding station 242, and each first guide post 26 is vertically arranged on the main frame 10 and passes through the corresponding first through hole 244. The second lifting component 30 also includes at least two second guide posts 36. The second support plate 34 is provided with second through holes 344. The number of second through holes 344 is equal to the number of second guide posts 36 and they correspond one-to-one. Each second through hole 344 is arranged around the second holding station 342. Each second guide post 36 is vertically arranged on the main frame 10 and passes through the corresponding second through hole 344.

[0045] In this embodiment, each first guide post 26 is arranged around the first holding station 242, thus limiting the position of the tray 101 placed in the first holding station 242, preventing the position of the tray 101 from shifting, and ensuring that the gripping component 40 can accurately grip the tray 101. Secondly, due to the cooperation between the first guide post 26 and the corresponding first through hole 244, the installation position of the first support plate 24 is limited, thereby ensuring that the position of the first holding station 242 on the first support plate 24 is relatively accurate, and thus ensuring that the gripping component 40 can accurately grip the tray 101. In addition, when the first lifting mechanism 22 drives the first support plate 24 to rise and fall, the first guide post 26 and the corresponding first through hole 244 cooperate with each other, thereby guiding the movement of the first support plate 24 in the vertical direction.

[0046] Each second guide post 36 is arranged around the second holding station 342, thus limiting the position of the tray 101 placed in the second holding station 342, preventing the tray 101 from shifting, and ensuring that the gripping component 40 can accurately grip the tray 101. Secondly, due to the cooperation between the second guide post 36 and the corresponding second through hole 344, the installation position of the second support plate 34 is limited, thereby ensuring that the position of the second holding station 342 on the second support plate 34 is relatively accurate, and thus ensuring that the gripping component 40 can accurately grip the tray 101. In addition, when the second lifting mechanism 32 drives the second support plate 34 to rise and fall, the second guide post 36 and the corresponding second through hole 344 cooperate with each other, thereby guiding the movement of the second support plate 34 in the vertical direction.

[0047] In one embodiment, the first through hole 244 includes a first strip-shaped through hole 2442 and a first strip-shaped notch 2444. The first support plate 24 has first strip-shaped through holes 2442 at one opposite end and first strip-shaped notches 2444 at the other opposite end. A first guide post 26 is inserted into each first strip-shaped through hole 2442 and each first strip-shaped notch 2444.

The first support plate 24 has a large degree of freedom along the second direction, thus facilitating installation. Furthermore, adjusting the corresponding first guide post 26 also allows adjustment of the dimension of the first holding station 242 along the second direction, thus enabling the first holding station 242 to accommodate trays 101 of different sizes. In addition, after the first guide post 26 is installed, the first strip-shaped through holes 2442 of the first support plate 24 can be inserted into the corresponding first guide post 26, and then the first strip-shaped notches 2444 of the first support plate 24 can be fitted onto the corresponding first guide post 26, thus further improving the convenience of installation.

[0049] By providing the second strip-shaped through hole 3442, the position of the corresponding second guide post 36 relative to the second support plate 34 can be adjusted along the first direction during installation. The second support plate 34 has a large degree of freedom along the first direction, thus facilitating installation. Furthermore, adjusting the corresponding second guide post 36 also allows adjustment of the dimension of the second holding station 342 along the first direction. By providing the second strip-shaped notch 3444, the position of the corresponding second guide post 36 relative to the second support plate 34 can also be adjusted along the second direction during installation. The second support plate 34 has a large degree of freedom along the second direction, thus facilitating installation. Furthermore, adjusting the corresponding second guide post 36 also allows adjustment of the dimension of the second holding station 342 along the second direction, thus enabling the second holding station 342 to accommodate trays 101 of different sizes. In addition, after the second guide post 36 is installed, the second strip-shaped through holes 3442 of the second support plate 34 can be inserted into the corresponding second guide post 36, and then the second strip-shaped notches 3444 of the second support plate 34 can be fitted onto the corresponding second guide post 36, thus further improving the convenience of installation.

[0050] In one specific embodiment, there are four first strip-shaped through holes 2442, with two first strip-shaped through holes 2442 respectively provided at each of the opposite ends of the first support plate 24. There are two first strip-shaped notches 2444, with one first strip-shaped notch 2444 respectively provided at each of the other opposite ends of the first support plate 24. There are four second strip-shaped through holes 3442, with two second strip-shaped through holes 3442 respectively provided at each of the opposite ends of the second support plate 34. There are two second strip-shaped notches 3444, with one second strip-shaped notch 3444 respectively provided at each of the other opposite ends of the second support plate 34.

[0051] In one embodiment, the top of each first guide post 26 is inclined in a direction away from the first holding station 242, so that a first guide opening is formed between each first guide post 26; The top of each second guide post 36 is tilted away from the second holding station 342 so that a second guide opening is formed between each second guide post 36.

[0052] In this embodiment, the first guide port has a guiding function, enabling the stacked pallets 101 to be smoothly placed into the first holding station 242. The second guide port has a guiding function, enabling the stacked pallets 101 to be smoothly placed into the second holding station 342.

[0053] Specifically, the first guide opening is a funnel-shaped opening formed by multiple first guide posts 26, with the distance between the tops of each first guide post 26 gradually increasing from bottom to top. The second guide opening is a funnel-shaped opening formed by multiple second guide posts 36, with the distance between the tops of each second guide post 36 gradually increasing from bottom to top.

[0054] Please refer to the above as well. Figures 4 to 6 In one embodiment, the gripping component 40 includes a lateral movement mechanism 42, a telescopic drive mechanism 44, and a needle 46; The lateral movement mechanism 42 is mounted on the main frame 10, and the first lifting assembly 20, the second lifting assembly 30, and the conveying assembly 50 are located below the lateral movement mechanism 42. The telescopic drive mechanism 44 includes a fixed end 442 and a telescopic end 444. The fixed end 442 is located on the transverse moving mechanism 42, and the telescopic end 444 is located below the fixed end 442. The needle 46 is located on the telescopic end 444.

[0055] In this embodiment, the above structure enables the trays 101 of the first lifting component 20 and the second lifting component 30 to be quickly and accurately transferred to the conveying component 50.

[0056] In one specific embodiment, the lateral movement mechanism 42 includes two racks 422, two gears 424, a mounting plate 426, and a second motor 428. The two racks 422 are mounted on the main frame 10 and are parallel to each other. The two gears 424 are rotatably mounted on the mounting plate 426 and mesh with their respective racks 422. The second motor 428 is mounted on the mounting plate 426 and is connected to the two gears 424 for transmission to drive the gears 424 to rotate. The first lifting assembly 20, the second lifting assembly 30, and the conveying assembly 50 are located below the mounting plate 426. The fixed end 442 of the telescopic drive mechanism 44 is mounted on the mounting plate 426. After the second motor 428 drives the gears 424 to rotate, the gears 424 can move along the length of the racks 422, thereby driving the mounting plate 426 to move. Through the engagement of gear 424 and rack 422, and the rotation of gear 424 driven by the second motor 428, mounting plate 426 can move above conveying assembly 50, or above first lifting assembly 20, or above second lifting assembly 30. After the first lifting assembly 20 or second lifting assembly 30 lifts pallet 101 to a first preset height, mounting plate 426 moves above the first lifting assembly 20 or second lifting assembly 30. Then, the telescopic end 444 of telescopic drive mechanism 44 extends downwards, causing needle 46 to pierce the uppermost pallet 101. Then, the first lifting assembly 20 or second lifting assembly 30 moves the remaining pallets 101 down to a second preset height. Simultaneously, the mounting plate 426 moves above the conveying assembly 50, and the telescopic end 444 of the telescopic drive mechanism 44 retracts. Because the needle 46 penetrates the tray 101 only shallowly, and due to the weight of the tray 101 itself, the needle 46 can withdraw from the tray 101, causing the tray 101 to fall onto the conveying assembly 50. The above steps are then repeated until all trays 101 on the first lifting assembly 20 and the second lifting assembly 30 are conveyed onto the conveying assembly 50. The conveying assembly 50 can be the aforementioned belt conveyor mechanism or other transmission mechanisms, which will not be described in detail here. The tray 101 is made of rigid paper.

[0057] In one specific embodiment, such as Figure 1 As shown, Figure 1 The X direction shown is the second direction, and the Y direction is the first direction. The second direction is the same as the movement direction of the lateral movement mechanism 42, and the first direction is perpendicular to the movement direction of the lateral movement mechanism 42.

[0058] In one embodiment, there are two telescopic drive mechanisms 44. The two telescopic drive mechanisms 44 are inclined relative to the horizontal plane. The fixed ends 442 of the two telescopic drive mechanisms 44 are close to each other, and the telescopic ends 444 of the two telescopic drive mechanisms 44 are far apart from each other. The two telescopic ends 444 are respectively provided with needles 46.

[0059] In this embodiment, the telescopic end 444 also extends or retracts at an angle. Therefore, the telescopic end 444 can also tilt to drive the needles 46 to pierce the tray 101. When the two needles 46 of the two telescopic ends 444 are inserted into a tray 101 respectively, the two needles 46 can form a stronger connecting force on the tray 101, which can prevent the tray 101 from falling off during the transfer to the conveying assembly 50. In addition, since the needles 46 on the two telescopic ends 444 are inserted into the tray 101 at an angle, when the telescopic end 444 drives the needles 46 to retract, the component force of the connecting force of each needle 46 on the tray 101 changes significantly, making it easier for the needles 46 to exit from the tray 101. Each telescopic end 444 can be provided with multiple needles 46, and the multiple needles 46 located on the same telescopic end 444 are parallel to each other, which facilitates smooth insertion into the tray 101.

[0060] In one specific embodiment, the telescopic drive mechanism 44 includes a cylinder, a piston, and a piston rod. The cylinder is connected to an air source such as an air compressor. The piston is located inside the cylinder, and the piston rod passes through the piston, with a portion of the piston rod extending to the outside. A fixed end 442 is located on the cylinder, or the cylinder itself can be the fixed end 442. A telescopic end 444 is located on the piston rod, or the portion of the piston rod extending to the outside is the telescopic end 444.

[0061] In one embodiment, the gripping component 40 further includes two adjustment mechanisms 48, which are disposed on the lateral movement mechanism 42. Each adjustment mechanism 48 is connected to a corresponding fixed end 442 for adjusting the distance between the two fixed ends 442.

[0062] In this embodiment, by adjusting the distance between the two fixed ends 442, the needle 46 can grasp trays 101 of different sizes.

[0063] In one specific embodiment, each adjusting mechanism 48 includes a second lead screw 482, a second lead screw nut 484, two second lead screw seats 486, and a handle disc 488. The second lead screw seats 486 are mounted on the top surface of the mounting plate 426. The second lead screw 482 is rotatably mounted on the two second lead screw seats 486. The second lead screw nut 484 is sleeved on the second lead screw 482. The fixed end 442 of the telescopic drive mechanism 44 is connected to the second lead screw nut 484. The handle disc 488 is mounted on the end of the second lead screw 482. The handle disc 488 can drive the second lead screw 482 to rotate, thereby causing the second lead screw nut 484 and the fixed end 442 to move axially along the second lead screw 482. The second lead screws 482 of the two adjusting mechanisms 48 are parallel to each other or located on the same straight line, thereby allowing adjustment of the distance between the two fixed ends 442.
