Detailed Implementation

[0062] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0063] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0064] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0065] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0066] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0067] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 1 and Figure 9The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0068] like Figures 1-17 As shown, according to a first aspect of the embodiments of this application, a tray buffer mechanism 100 is provided, including two holding components 1 and a lifting component 2; the two holding components 1 are arranged opposite to each other; the lifting component 2 is located between the two holding components 1, the lifting component 2 includes a lifting part 21 and a first driving member 22, the lifting part 21 is disposed at the driving end of the first driving member 22, and the first driving member 22 is capable of driving the lifting part 21 to move.

[0069] For clarity, the two retaining components 1 are labeled as the first retaining component 1a and the second retaining component 1b, respectively.

[0070] The pallet buffer mechanism 100 of this application is used to stack multiple individual pallets 300 together to facilitate the transport of multiple recycled pallets 300.

[0071] like Figure 1 , Figure 5 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, the tray buffer mechanism 100 includes two holding components 1 and one lifting component 2; the two holding components 1 are respectively labeled as the first holding component 1a and the second holding component 1b. The two holding components 1 are arranged opposite to each other along the Y direction, that is, the first holding component 1a and the second holding component 1b are spaced apart along the Y direction. In the Y direction, the lifting component 2 is disposed between the first holding component 1a and the second holding component 1b, and the tray 300 is also located between the first holding component 1a and the second holding component 1b. In the Z direction, the tray 300 is located above the lifting component 2.

[0072] To further explain, the lifting assembly 2 includes a lifting part 21 and a first driving member 22. The lifting part 21 is located at the driving end of the first driving member 22, and the first driving member 22 can drive the lifting part 21 to move along the Z direction.

[0073] The working process of the material tray buffer mechanism 100 is illustrated by a specific embodiment. For example, three trays 300, namely the first tray, the second tray, and the third tray, are placed between the first holding component 1a and the second holding component 1b. The first tray, the second tray, and the third tray are arranged from top to bottom in the Z direction. Currently, it is necessary to return the fourth tray, which has been unloaded, to the bottom of the third tray so that the first tray, the second tray, the third tray, and the fourth tray can be stacked. Specifically, the first holding component 1a and the second holding component 1b can keep the stacked first tray, the second tray, and the third tray in a preset position. The fourth tray is located on the lifting part 21. The first driving component 22 drives the lifting part 21 to move upward in the Z direction, that is, drives the fourth tray to move upward to the bottom of the third tray and contact the third tray. The first holding component 1a and the second holding component 1b keep the stacked first tray, the second tray, the third tray, and the fourth tray in the preset position. The first driving component 22 drives the lifting part 21 to move downward in the Z direction to prepare to move the next returned tray 300 to the bottom of the fourth tray in the Z direction.

[0074] In this embodiment, the first holding component 1a and the second holding component 1b can hold the stacked pallets 300 in a preset position, and the lifting component 2 stacks the returning pallets 300 together at the bottom of the multiple pallets 300; compared with placing the returning pallets 300 from the top, there is no need to set up a separate handling mechanism, which can save space, save costs and improve conveying efficiency.

[0075] In one alternative embodiment, any of the retaining components 1 includes at least one support member 11a, the support member 11a including a support base 11 and a mounting base 12, the support base 11 being rotatably connected to the mounting base 12;

[0076] The support base 11 includes a support surface 111;

[0077] The support base 11 includes a first state and a second state, and the support base 11 is rotatable relative to the mounting base 12 about the axis in the X direction from the first state to the second state;

[0078] In the first state, the support surface 111 faces the Z direction; in the second state, the support surface does not face the Z direction.

[0079] like Figures 1-3 As shown, each retaining component 1 includes at least one support member 11a, and the support members 11a of the first retaining component 1a and the support members 11a of the second retaining component 1b are arranged at intervals along the Y direction.

[0080] like Figure 2 , Figure 3 , Figure 14 and Figure 15 As shown, the support member 11a includes a support base 11 and a mounting base 12. The mounting base 12 is used to be mounted on the frame of the conveying device 200. The support base 11 is rotatably connected to the mounting base 12. The support base 11 can rotate relative to the mounting base 12 about the axis in the X direction.

[0081] The support base 11 includes a support surface 111. When the first tray, the second tray, and the third tray are in preset positions, the support base 11 is in a first state. Specifically, the third tray is located on the support surface 111 of the support base 11 of the first retaining component 1a and the support surface 111 of the support base 11 of the second retaining component 1b, thus providing support for the first tray, the second tray, and the third tray. When it is necessary to stack the fourth tray below the third tray, the fourth tray is located on the lifting part 21. The first driving member 22 drives the lifting part 21 to move upward along the Z direction, gradually approaching the support base 11. The fourth tray will abut against the support base 11. The first driving member 22 continues to drive the lifting part 21 to move upward along the Z direction, and the fourth tray will drive the support base 11 to rotate around the X direction. At this point, the support surface 111 is gradually rotated from the direction facing Z to the direction facing Y so that the support surface is no longer facing Z (at this time, the support seat 11 is in the second state). In this state, the fourth tray can continue to move upward along the Z direction to avoid the support seat 11 blocking the fourth tray from continuing to move upward. The first driving member 22 continues to drive the lifting part 21 to move upward along the Z direction. The fourth tray contacts the third tray, the third tray disengages from the support seat 11, and the fourth tray is located above the support seat 11 in the Z direction. The support seat 11 will then reset, that is, the support surface 111 faces Z. The first driving member 22 drives the lifting part 21 to move downward along the Z direction, placing the fourth tray on the support surface 111, thereby completing the stacking of the trays 300.

[0082] In this embodiment, when the support base 11 is in the first state, multiple trays 300 are supported and held in a preset position by the support surface 111. When it is necessary to continue stacking the trays 300, the lifting component 2 lifts the tray 300 above the support base 11 and then places it on the support surface 111. The holding component 1 in this embodiment has a simple structure and can also play a supporting role when storing. There is no need to set up a separate support component, which makes the structure of the tray buffer mechanism 100 more compact.

[0083] In one optional embodiment, the mounting base 12 has a groove 121, and a portion of the support base 11 is located in the groove 121 and rotatably connected to the mounting base 12;

[0084] In the first state, a portion of the support surface 111 protrudes from the mounting base 12 in the Y direction; in the second state, the support surface 111 does not protrude from the mounting base 12 in the Y direction.

[0085] like Figure 2 , Figure 3 , Figure 14 and Figure 15 As shown, the mounting base 12 has a groove 121, and a portion of the support base 11 is located in the groove 121 and rotatably connected to the mounting base 12, so that the support base 11 can rotate about the axis in the X direction. When the support base 11 is in the first state, a portion of the support surface 111 protrudes from the mounting base 12 in the Y direction. Specifically, when the support base 11 is in the first state, a portion of the support surface 111 protrudes from the mounting base 12, and the support surface 111 can support multiple trays 300 to be held in a preset position. When it is necessary to stack a single return tray 300 under multiple trays 300, when the support base 11 is in the second state, the support base 11 rotates about the axis in the X direction so that the support surface does not protrude from the mounting base 12 in the Y direction, so that the fourth tray can move from below the support base 11 to above the support base 11 in the Z direction. When the support base 11 returns from the second state to the first state, multiple trays 300 are placed on the support surface 111 to support the multiple trays 300.

[0086] Among them, such as Figure 16 As shown, the support base 11 is provided with a first rotating shaft 115 and a second rotating shaft 116. The first rotating shaft 115 and the second rotating shaft 116 are respectively located on both sides of the support base 11 in the X direction. The first rotating shaft 115 and the second rotating shaft 116 are both connected to the mounting base 12 in the groove 121. The support base 11 can rotate about the X direction relative to the axis of the first rotating shaft 115 and the second rotating shaft 116.

[0087] In an optional embodiment, the support base 11 further includes a first end face 112 and a second end face 114, wherein the first end face 112 is arranged at an angle to the support surface 111, and the first end face 112 is closer to the support surface 111 than the second end face 114.

[0088] The groove 121 includes a third end face 1211, which faces the Y direction. The first end face 112 is arranged opposite to the third end face 1211, and the second end face 114 is arranged opposite to the third end face 1211.

[0089] In the first state, there is a gap between the first end face 112 and the third end face 1211 in the Y direction, and the second end face 114 abuts against the third end face 1211. In the second state, there is a gap between the second end face 114 and the third end face 1211.

[0090] like Figures 14-16 As shown, the support base 11 also includes a first end face 112 and a second end face 114; wherein, both the first end face 112 and the second end face 114 are located within the groove; the first end face 112 is set at an angle to the support surface 111, which can be understood as the first end face 112 and the support surface 111 not being located on the same plane, and the angle between the first end face 112 and the support surface 111 can be 90° or between 90° and 180°, and the first end face 112 and the support surface 111 can be connected or not connected; the second end face 114 is arranged at an angle to the support surface 111, which can be understood as the second end face 114 and the support surface 111 not being located on the same plane, and the angle between the second end face 114 and the support surface 111 can be 90°.

[0091] To further explain, the groove 121 includes a third end face 1211, which is one of the inner walls of the groove 121. The third end face 1211 faces the Y direction and the tray 300. The first end face 112 and the second end face 114 are both located in the groove 121. The first end face 112 is opposite to the third end face 1211, and the second end face 114 is opposite to the third end face 1211. The first end face 112 is located above the second end face 114 in the Z direction.

[0092] To further explain, when the support base 11 is in the first state, there is a gap between the first end face 112 and the third end face 1211 in the Y direction, and the second end face 114 abuts against the third end face 1211. Specifically, since the second end face 114 is located below the first end face 112 in the Z direction, when the tray 300 is located on the support surface 111, the tray 300 exerts a downward force on the support surface 111 in the Z direction. The second end face 114 abuts against the third end face 1211, and the third end face 1211 can prevent the support base 11 from continuing to rotate around the axis in the X direction, thereby enabling the support base 11 to support the tray 300. When the support base 11 rotates from the first state to the second state, the support base 11 is subjected to an upward force in the Z direction. Since there is a gap between the first end face 112 and the third end face 1211, the support base 11 can rotate around the axis in the X direction without being blocked by the third end face 1211.

[0093] like Figure 2 , Figure 3 , Figure 14 , Figure 15 and Figure 17As shown, in an optional embodiment, the support base 11 further includes an abutment surface 113, which is connected to the support surface 111 at a first angle d, where the first angle d is an acute angle. Specifically, when the support base 11 is in the first state, the support surface 111 faces the Z direction, and the abutment surface 113 is located below the support surface 111 in the Z direction, and the abutment surface 113 is connected to the support surface 111 at a first angle d, where the first angle d is an acute angle. That is, when the support base 11 is in the first state, the abutment surface 113 is an inclined surface. When the first driving member 22 drives the lifting part 21 to move upward along the Z direction, the fourth tray located in the lifting part 21 contacts the abutment surface 113 to drive the support base 11 to rotate around the axis in the X direction. The abutment surface 113 is inclined, which facilitates the contact between the fourth tray and the abutment surface 113, and can reduce the frictional resistance of the support base 11 during rotation, reduce energy loss during transmission, and efficiently utilize the driving force of the first driving member 22.

[0094] In one optional embodiment, the support 11 has a first mounting hole 117, and the mounting 12 has a second mounting hole, the axis of the second mounting hole being parallel to the axis in the Y direction;

[0095] The support member 11a further includes an elastic member 13, one end of which is disposed in the first mounting hole 117, and the other end of which is disposed in the second mounting hole. The elastic member 13 enables the support base 11 to rotate from the second state to the first state.

[0096] like Figure 16 and Figure 17 As shown, the support base 11 has a first mounting hole 117, and the mounting base 12 has a second mounting hole. The axis of the second mounting hole is parallel to the axis in the Y direction. When the support base 11 is in the first state, the first mounting hole 117 and the second mounting hole are concentrically arranged. When the support base 11 is in the second state, the first mounting hole 117 is located above the second mounting hole in the Z direction. One end of the elastic element 13 is disposed in the first mounting hole 117, and the other end of the elastic element 13 is disposed in the second mounting hole. Therefore, when the support base 11 is in the first state, the elastic element 13 is unaffected. In the force state, when the support seat 11 changes from the first state to the second state, the elastic element 13 is subjected to an external force, and one end of it moves upward along the Z direction and undergoes elastic deformation, storing elastic potential energy. When the fourth tray is above the support seat 11, the external force on the elastic element 13 disappears, and the elastic element 13 returns to its original shape, releasing the stored energy, thereby resetting the support seat 11 from the second state to the first state. In this embodiment, the support seat 11 can be reset by the elastic element 13, thereby improving the automation performance of the tray buffer mechanism 100.

[0097] Among them, the elastic element 13 can be a helical spring.

[0098] In another optional embodiment, the support member 11a further includes a torsion spring, which is disposed at the rotatable connection between the support base 11 and the mounting base 12. The torsion spring enables the support base 11 to rotate from the second state to the first state. Specifically, when the support base 11 is in the first state, the torsion spring is in an unloaded state. When the support base 11 changes from the first state to the second state, the torsion spring is subjected to an external force and undergoes torsion, generating elastic deformation and storing elastic potential energy. When the fourth tray is located above the support base 11, the external force on the torsion spring disappears, and the torsion spring returns to its original shape, releasing the stored energy, thereby resetting the support base 11 from the second state to the first state. In this embodiment, the torsion spring enables the support base 11 to be reset, thereby improving the automation performance of the tray buffer mechanism 100.

[0099] In an optional embodiment, any of the retaining components 1 includes two support members 11a, which are spaced apart along the X direction. Specifically, the first retaining component 1a includes two support members 11a, respectively labeled as the first support member and the second support member, and the second retaining component 1b includes two support members 11a, respectively labeled as the third support member and the fourth support member. The first and second support members are spaced apart along the X direction, the third and fourth support members are spaced apart along the X direction, the first and third support members are spaced apart along the Y direction, and the second and fourth support members are spaced apart along the Y direction. Therefore, the first, second, third, and fourth support members are arranged in a rectangular or square shape to improve support stability.

[0100] In another alternative embodiment, any of the holding components 1 includes a second drive member 14 and a clamping member 13, the clamping member 13 being disposed at the drive end of the second drive member 14, the second drive member 14 being capable of driving the clamping member 13 to move along the Y direction.

[0101] like Figure 9 and Figure 10As shown, the retaining assembly 1 includes a second driving member 14 and a clamping member 13. The clamping member 13 is disposed at the driving end of the second driving member 14, and the second driving member 14 can drive the clamping member 13 to move along the Y direction. Specifically, the first retaining assembly 1a and the second retaining assembly 1b are arranged at intervals along the Y direction, and a plurality of trays 300 are located between the first retaining assembly 1a and the second retaining assembly 1b. In a specific embodiment, the second driving member 14 of the first retaining assembly 1a drives the corresponding clamping member 13 to move along the Y direction, abutting against the side of the third tray. The second drive member 14 of the holding component 1b drives the corresponding clamping member 13 to move along the Y direction, so that the side of the third tray abuts against it. Therefore, the clamping members 13 of the first holding component 1a and the second holding component 1b can keep the third tray, the second tray, and the first tray in a preset position. When it is necessary to stack the fourth tray under the third tray, the fourth tray is now above the lifting part 21. The first drive member 22 drives the lifting part 21 to move upward along the Z direction so that the fourth tray contacts the third tray. After the fourth tray contacts the third tray, The second drive member 14 of the first holding assembly 1a drives the corresponding clamping member 13 to move away from the third tray along the Y direction. The second drive member 14 of the second holding assembly 1b drives the corresponding clamping member 13 to move away from the third tray along the Y direction. At this time, the third tray, the second tray, and the first tray are no longer clamped by the first holding assembly 1a and the second holding assembly 1b, but are supported by the lifting assembly 2. The first drive member 22 continues to drive the lifting part 21 to move upward along the Z direction, so that the fourth tray moves to the position of the clamping member 13. The second drive member 14 of the holding component 1a drives the corresponding clamping member 13 to move along the Y direction and abut against the side of the fourth tray. The second drive member 14 of the second holding component 1b drives the corresponding clamping member 13 to move along the Y direction and abut against the side of the fourth tray. Therefore, the clamping members 13 of the first holding component 1a and the second holding component 1b can keep the fourth tray, the third tray, the second tray, and the first tray in a preset position. The first drive member 22 can then drive the lifting part 21 to move downward along the Z direction, thus completing the stacking of the fourth tray. In this embodiment, the clamping member 13 is driven by the second drive member 14 to clamp multiple trays 300. This structure is simple and makes the structure of the tray buffer mechanism 100 more compact.

[0102] like Figure 10As shown, in an optional embodiment, the clamping member 13 includes a first mounting plate 131 and at least one pressure plate 132. In the Y direction, the pressure plates 132 of the two retaining components 1 are disposed opposite to the corresponding first mounting plate 131. Specifically, in the Y direction, the pressure plates 132 of the two retaining components 1 are disposed opposite to each other. It can be understood that the pressure plates 132 of the first retaining component 1a and the pressure plates 132 of the second retaining component 1b are both on the side of the first mounting plate 131 facing the tray 300. The first mounting plate 131 is disposed at the driving end of the second driving member 14. When the second driving member 14 drives the first mounting plate 131 in the Y direction, the pressure plates 132 will move in the Y direction and contact the tray 300. The pressure plates 132 of the first retaining component 1a and the second retaining component 1b together clamp the tray 300 in the Y direction so that the tray 300 is held in a preset position.

[0103] like Figure 9 As shown, in an optional embodiment, the lifting part 21 includes a lifting plate 211, which is disposed at the driving end of the first driving member 22; in this embodiment, the tray buffer mechanism 100 is suitable for a conveyor belt conveying method where the transmission mechanism 3 is a conveyor belt; specifically, as Figure 6 As shown, the transmission mechanism 3 consists of two transmissions arranged opposite each other along the Y direction. The lifting part 21 is located between the two transmission belts. The first driving member 22 drives the lifting plate 211 to move along the Z direction to lift the pallet 300 or place the pallet 300 on the conveyor belt.

[0104] like Figures 5-8 As shown, in an optional embodiment, the lifting part 21 includes a second mounting plate 212 and a plurality of lifting rods 213. The plurality of lifting rods 213 are disposed on the second mounting plate 212, and the second mounting plate 212 is disposed on the driving end of the first driving member 22. The plurality of lifting rods 213 are divided into a first group and a second group, which are spaced apart relative to the Y direction. The transmission mechanism 3 is located between the first group and the second group in the Y direction. The first driving member 22 drives the second mounting plate 212 to move along the Z direction, thereby driving the plurality of lifting rods 213 to move along the Z direction to lift the pallet 300 or place the pallet 300 on the transmission mechanism 3. In this embodiment, the pallet buffer mechanism 100 is suitable for conveying methods where the transmission mechanism 3 is a conveyor belt, and is also suitable for conveying methods where the suction cup is used. It has higher compatibility and lower cost.

[0105] like Figures 1-13As shown, according to a second aspect of the embodiments of this application, a conveying device 200 is provided, including a transmission mechanism 3, a first buffer station A, and a tray buffer mechanism 100; the transmission mechanism 3 is capable of conveying a tray 300 along a preset direction, for example, conveying the tray 300 to a preset position along the X direction and / or Z direction; the first buffer station A is located at the transmission mechanism 3, and the tray buffer mechanism 100 is located at the first buffer station A, the first buffer station A being used to store multiple return trays 300; the two holding components 1 of the tray buffer mechanism 100 are located on both sides of the transmission mechanism 3 at the first buffer station A, and the lifting component 2 is located at the transmission mechanism 3; it can be understood that the multiple return trays 300 are located above the lifting component 2 and between the first holding component 1a and the second holding component 1b, the transmission mechanism 3 moves a single return tray 300 to the first buffer station A, and the tray buffer mechanism 100 stacks it under the multiple trays 300.

[0106] The conveying device 200 of this application can stack a single pallet 300 on the bottom of multiple pallets 300 without the need for a separate handling mechanism, thus enabling the stacking of multiple pallets 300. In this embodiment, the conveying device 200 has a more compact structure, occupies less space, and has higher conveying efficiency.

[0107] like Figure 1 As shown, at the first buffer station A, a first baffle A0 is set up, and four first baffles A0 form a hopper for the buffer tray 300. The number of first baffles A0 can be increased or decreased as needed.

[0108] like Figure 1 , Figure 6 , Figure 9 and Figure 11 As shown, in an optional embodiment, the conveying device 200 further includes a second buffer station B, which is located at the transmission mechanism 3. The pallet 300 located at the second buffer station B is conveyed to the first buffer station A via the transmission mechanism 3. The second buffer station B is used to store the pallet 300 filled with materials. After loading, the materials are output to the first buffer station A via the transmission mechanism 3 for stacking via the pallet buffer mechanism 100.

[0109] Similarly, such as Figure 1 and Figure 9 As shown, at the second buffer station B, a second baffle B0 is provided, and a hopper for the buffer tray 300 is formed between the second baffles B0. The number of second baffles B0 can be increased or decreased as needed.

[0110] In one optional embodiment, the transmission mechanism 3 includes a first transmission section 31a, a second transmission section 32a, and a lifting component 33a. The first transmission section 31a and the second transmission section 32a are spaced apart along the Z direction, and the lifting component 33a is arranged along the X direction with the first transmission section 31a and the second transmission section 32a. The first buffer station A is located in the first transmission section 31a, and the second buffer station B is located in the second transmission section 32a.

[0111] The lifting assembly 33a includes a third driving member 332a and a third conveying section 331a. The third conveying section 331a is connected to the driving end of the third driving member 332a, and the third driving member 332a can drive the third conveying section 331a to move along the Z direction.

[0112] Among them, a full pallet is a pallet 300 containing materials; an empty pallet is a pallet 300 without materials.

[0113] like Figure 9 , Figure 11 and Figure 13 As shown, the transmission mechanism 3 includes a first conveying section 31a, a second conveying section 32a, and a lifting assembly 33a. The first conveying section 31a and the second conveying section 32a are arranged along the Z direction, with the first conveying section 31a located below the second conveying section 32a in the Z direction. The first buffer station A is located in the first conveying section 31a, and the second buffer station B is located in the second conveying section 32a. This can be understood as follows: for example, a full tray is placed in the second buffer station B, and the transmission mechanism 3 moves it to the loading / unloading station C for loading. After the full tray is loaded, it becomes an empty tray, which is then moved to the first buffer station A for recycling. The arrangement of the first buffer station A and the second buffer station B in the Z direction can save space occupied by the conveying device 200.

[0114] To further explain, the lifting assembly 33a is arranged along the X direction with the first conveying section 31a and the second conveying section 32a. The lifting assembly 33a is used to move the tray 300 located in the second conveying section 32a to the first conveying section 31a. The lifting assembly 33a includes a third conveying section 331a and a third driving member 332a. The third driving member 332a can drive the third conveying section 331a to move along the Z direction. That is, the third driving member 332a can drive the third conveying section 331a to be on the same horizontal plane as the second conveying section 32a in the Z direction, or it can be on the same horizontal plane as the first conveying section 31a in the Z direction. Specifically, the first conveying section 31a can move the pallet 300 in the X direction, the second conveying section 32a can move the pallet 300 in the X direction, and the third conveying section 331a can move the pallet 300 in the X direction. The pallet 300 moves from the second conveying section 32a to the third conveying section 331a. The third driving member 332a drives the third conveying section 331a to move in the Z direction. The third conveying section 331a moves the pallet 300 to the first conveying section 31a. The pallet 300 is then recycled by the pallet buffer mechanism 100. In this embodiment, the pallet buffer mechanism 100 can support the pallet 300 by means of a support member 11a, or it can support the pallet 300 by means of a second driving member 14 driving a clamping member 13 to move in the Y direction to clamp the pallet 300.

[0115] like Figure 9 , Figure 11 and Figure 13 As shown, in an embodiment where the first buffer station A and the second buffer station B are arranged in the Z direction, the conveying device 200 further includes a loading / unloading station C. The loading / unloading station C is spaced apart from the first buffer station A along the X direction and is located in the third conveying section 331a. The pallet 300 located at the second buffer station B is moved to the third conveying section 331a via the second conveying section 32a. After loading or unloading is completed in the third conveying section 331a, the third driving member 332a drives the third conveying section 331a to move along the Z direction, so that the third conveying section 331a and the first conveying section 31a are on the same horizontal plane in the Z direction. The pallet buffer mechanism 100 then recycles the pallet 300. In this embodiment, the pallet 300 is located on the third conveying section 331a for loading or unloading, thereby saving processes and improving efficiency.

[0116] like Figure 1 and Figure 5 As shown, in an embodiment where the first buffer station A and the second buffer station B are arranged along the X direction, the conveying device 200 further includes a loading and unloading station C, and the first buffer station A, the loading and unloading station C and the second buffer station B are arranged sequentially along the X direction.

[0117] The transmission mechanism 3 includes a first driving component 31b, a first moving component 32b, and a second moving component 33b. The first moving component 32b and the second moving component 33b are spaced apart along the X direction. The first driving component 31b can drive the first moving component 32b and the second moving component 33b to move along the X direction. The first moving component 32b and the second moving component 33b can move between the first buffer station A, the loading / unloading station C, and the second buffer station B.

[0118] Specifically, both the first moving component 32b and the second moving component 33b are used to transfer the pallet 300. The first moving component 32b and the second moving component 33b are spaced apart along the X direction. When the first moving component 32b is located at the second buffer station B, the second moving component 33b is located at the loading / unloading station C. When the first moving component 32b is located at the loading / unloading station C, the second moving component 33b is located at the first buffer station A. The first moving component 32b is used to move the pallet 300 from the second buffer station B to the loading / unloading station C, and the second moving component 33b is used to move the pallet 300 that has been moved to the loading / unloading station C to the first buffer station A, so that the pallet 300 can be recycled by the pallet buffer mechanism 100. In this embodiment, the pallet buffer mechanism 100 can support the pallet 300 by means of a support member 11a, or it can support the pallet 300 by means of a second driving member 14 driving the clamping member 13 to move along the Y direction to clamp the pallet 300.

[0119] The second buffer station B holds a full pallet, and the first buffer station A holds an empty pallet. Taking the case where the loading / unloading station C has a pallet 300 as an example, the movement steps of the transmission mechanism 3 are as follows:

[0120] S1, the first moving component 32b is located at the second buffer station B, the second moving component 33b is located at the loading and unloading station C, the first driving component 31b drives the first moving component 32b and the second moving component 33b to move simultaneously along the X direction, the first moving component 32b moves the full tray located at the second buffer station B to the loading and unloading station C, and the second moving component 33b moves the empty tray located at the loading and unloading station C to the first buffer station A;

[0121] S2, the first driving component 31b drives the first moving component 32b and the second moving component 33b to move simultaneously along the X direction. The first moving component 32b moves unloaded from the loading / unloading station C to the second buffer station B, and the second moving component 33b moves unloaded from the first buffer station A to the loading / unloading station C. Then, steps S1 and S2 are repeated.

[0122] In this embodiment, the transmission mechanism 3 can simultaneously realize two moving processes, which can simultaneously move a full tray to the loading / unloading station C and move an empty tray to the first buffer station A, thereby saving conveying time and improving work efficiency.

[0123] like Figure 5 As shown, in an optional embodiment, the first drive assembly 31b includes a mounting bracket 311b, a fourth drive member 313b, and a guide rail 312b. The first moving assembly 32b and the second moving assembly 33b are both connected to the mounting bracket 311b. The mounting bracket 311b and the guide rail 312b are slidably connected in the X direction. The mounting bracket 311b is connected to the output end of the fourth drive member 313b, and the fourth drive member 313b can drive the mounting bracket 311b to move in the X direction. The first moving component 32b and the second moving component 33b are both mounted on the mounting bracket 311b. The mounting bracket 311b provides mounting support for the first moving component 32b and the second moving component 33b, and enables the first moving component 32b and the second moving component 33b to move simultaneously in the X direction. The mounting bracket 311b is slidably connected to the guide rail 312b in the X direction. The fourth driving component 313b can drive the mounting bracket 311b to move in the X direction. The mounting bracket 311b will move relative to the guide rail 312b in the X direction. The guide rail 312b can provide support and guidance for the mounting bracket 311b to prevent the mounting bracket 311b from tilting during movement.

[0124] The first moving component 32b includes a suction cup for supporting the tray 300; or, the first moving component 32b includes a gripper for holding the tray 300.

[0125] The second moving component 33b includes a suction cup for supporting the tray 300; or, the second moving component 33b includes a gripper for holding the tray 300.

[0126] In one alternative implementation, such as Figure 1 and Figure 4 As shown, the conveying device 200 also includes two clamping mechanisms 4, which are located at the loading / unloading station C and spaced apart from both sides of the transmission mechanism 3 along the Y direction. The two clamping mechanisms 4 are used to clamp the pallet 300 that has moved to the loading / unloading station C, so that the first moving component 32b and the second moving component 33b can continue to perform their steps without waiting at the loading / unloading station C. Specifically, as... Figure 8As shown, the clamping mechanism 4 includes a second drive assembly 41 and a clamping part 42. The second drive assembly 41 can drive the clamping part 42 to move along the Y direction. The two clamping mechanisms 4 are a first clamping mechanism 4a and a second clamping mechanism 4b. The second drive assembly 41 of the first clamping mechanism 4a drives the corresponding clamping part 42 to move along the Y direction to move closer to the tray 300. The second drive assembly 41 of the second clamping mechanism 4b drives the corresponding clamping part 42 to move along the Y direction to move closer to the tray 300. The first clamping mechanism 4a and the second clamping mechanism 4b can clamp the tray 300. The first moving component 32b can move from the loading / unloading station C to the second buffer station B to continue moving the pallet 300. When the pallet 300 at the loading / unloading station C needs to be moved to the first buffer station A, the second driving component 41 of the first clamping mechanism 4a drives the corresponding clamping part 42 to move away from the pallet 300 along the Y direction, and the second driving component 41 of the second clamping mechanism 4b drives the corresponding clamping part 42 to move away from the pallet 300 along the Y direction, so that the pallet 300 can be released, and the pallet 300 can be moved to the first buffer station A by the second moving component 33b.
