Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical packaging technology, and in particular to a pallet feeding device. Background Technology
[0002] In the final production stage of the pharmaceutical industry, packaging drugs that have completed internal or final packaging is an indispensable key process under the GMP (Good Manufacturing Practice) regulatory framework. According to relevant requirements, the packaging process must minimize human intervention, ensure that the product is not subject to secondary contamination, and achieve traceability of batch, quantity, and quality status. Given these requirements, pallets are commonly used as drug buffers and turnover units in actual production.

To improve efficiency, pallets are further stacked and destacking / unstacking equipment is added, allowing more pallets to be transported on the pallet conveyor. However, the gripping devices of existing destacking / unstacking equipment are relatively large, making them prone to mechanical interference with the pallets, leading to pallet wear and deformation.

[0015] The pallet feeding device provided in this embodiment of the utility model has at least the following beneficial effects: The pallet feeding device provided in this embodiment of the utility model conveys pallets through a first conveying component and raises and lowers the pallets through a first lifting component and a boosting component.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0029] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0031] It should also be noted that the division of multiple embodiments in this utility model is only for the convenience of description and should not constitute a special limitation. Features in various embodiments can be combined and referenced in each other without contradiction. In the drawings, X indicates the first direction, Y indicates the second direction, and Z indicates the third direction, which is the vertical direction.
[0032] Due to production needs, material 51 needs to be transferred between different production lines. To improve conveying efficiency, material 51 is generally carried by pallets 50, and pallets 50 can be further stacked for convenient transport. Therefore, during the transfer of material 51, the stacked pallets 50 need to be disassembled one by one to facilitate the transfer of material 51 by the material transfer equipment. However, the gripping device of the existing pallet disassembly equipment is large in size, which easily causes mechanical interference with the pallet 50, has low adaptability, and is prone to wear and deformation of the pallet 50. At the same time, in the prior art, the bracket used to support the gripping device is usually a certain distance away from the conveying track to avoid interference with the conveying mechanism or pallet 50 during lifting or lowering. However, this makes the distance between the part of the gripping device that contacts the pallet 50 and the part of the bracket that supports the gripping device longer, that is, the lever arm is longer. As a result, the gripping device is subjected to a large bending moment under the leverage effect. Therefore, the load-bearing lifting capacity of the gripping device in the prior art is limited, and it is prone to damage.
[0033] Based on this, see Figures 1 to 3 This utility model provides a pallet feeding device 1, including a feeding and transfer device 30 and a pallet unloading device 10. The pallet unloading device 10 and the feeding and transfer device 30 are arranged sequentially along the pallet 50 conveying direction. The pallet 50 device can first unload stacked pallets 50, and then the feeding and transfer device 30 transfers the material 51 from the pallet 50, for example, transferring the material 51 to other conveyor lines. It is understood that the pallet 50 conveying direction refers to the direction of movement of the pallet 50 within the pallet feeding device 1.
[0034] The tray removal device 10 includes a first conveying assembly 12, a first lifting assembly 13, and multiple lifting assemblies 14. The multiple lifting assemblies 14 are located on both sides of the first conveying assembly 12, allowing them to simultaneously lift the tray 50 from both sides, thus making the tray 50 more stable when it rises or falls under the influence of the lifting assemblies 14. The first conveying assembly 12 forms a first mounting space 121, and at least a portion of the first lifting assembly 13 is located within the first mounting space 121. The first conveying assembly 12 can convey the tray 50, for example, by conveying the tray 50 between the two lifting assemblies 14, so that the tray 50 can be lifted by the lifting assemblies 14. It is understood that at least a portion of the first mounting space 121 and at least a portion of the first lifting assembly 13 are located between the two lifting assemblies 14, so that the first lifting assembly 13 can also lift and raise the tray 50 to cooperate with the lifting assemblies 14 in completing the tray removal process.
[0035] The lifting assembly 14 includes a support frame 141, a second lifting mechanism 142, a telescopic mechanism 143, a buckle plate 144, and a guide connector 145. The support frame 141 is located on one side of the first conveying assembly 12. The guide connector 145 is located on the top of the support frame 141. The telescopic mechanism 143 is located on the top of the support frame 141 and on the side of the support frame 141 opposite to the first conveying assembly 12. The buckle plate 144 is connected to the guide connector 145 and is drivenly connected to the telescopic mechanism 143. The second lifting mechanism 142 is located at the bottom of the support frame 141 and is drivenly connected to the support frame 141. The second lifting mechanism 142 can drive the support frame 141 to move up and down, thereby causing the telescopic mechanism 143, the buckle plate 144, and the guide connector 145 located on the top of the support frame 141 to move up and down. The buckle plate 144 is connected to the guide connector 145 provided on the support frame 141 and can be driven by the telescopic mechanism 143 to move in the direction guided by the guide connector 145, that is, towards the first conveying assembly 12 or away from the first conveying assembly 12. It is understood that the buckle plate 144 can abut against the tray 50 to support the tray 50. That is, at least a portion of the tray 50 is located above the buckle plate 144, while the support frame 141 and the second lifting mechanism 142 are located below the buckle plate 144. Therefore, the space above the buckle plate 144 occupied by the support frame 141 and the second lifting mechanism 142 can be effectively reduced, which helps to increase the contact area between the buckle plate 144 and the tray 50, so that the buckle plate 144 can support the tray 50 more stably and help to improve the stability of the lifting assembly 14. Furthermore, the telescopic mechanism 143 is located on the side of the support frame 141 opposite to the first conveying assembly 12, that is, the telescopic mechanism 143 is located on the side of the buckle plate 144 opposite to the first conveying assembly 12. In this way, the space occupied by the telescopic mechanism 143 on the top of the support frame 141 can be reduced, and the telescopic mechanism 143 can be prevented from obstructing the buckle plate 144, so that the contact area between the buckle plate 144 and the tray 50 is larger, and the buckle plate 144 can support the tray 50 more stably. The second lifting mechanism 142 is located at the bottom of the support frame 141 to stably drive the support frame 141, thereby preventing the buckle plate 144 from becoming unstable when supporting the tray 50 and moving up and down.
[0036] One embodiment of this utility model is described below. At least two stacked pallets 50 are conveyed to a first conveying assembly 12, and further conveyed by the first conveying assembly 12 to a plurality of lifting assemblies 14 disposed on both sides of the first conveyor. A second lifting mechanism 142 drives a support frame 141 to move, such that a buckle plate 144 corresponds to the second pallet 50 from bottom to top. A telescopic mechanism 143 drives the buckle plate 144 to move along the guide connector 145 toward the second pallet 50 until the buckle plate 144 engages with the second pallet 50. The second lifting mechanism 142 then drives the support frame 141 to rise, such that the buckle plate 144 lifts the second pallet 50 and above. In this way, the first pallet 50 is separated from the second and above pallets 50. The first conveying assembly 12 conveys the first pallet 50 to a material transfer device 30. The material transfer device 30 transfers the material 51 on the pallet 50 to other production lines, or transfers the material 51 from other production lines to the pallet 50. After the first pallet 50 is conveyed to the feeding transfer device 30, the first lifting assembly 13 rises to support the second and subsequent pallets 50. The latch plate 144, driven by the telescopic mechanism 143, retracts along the guide connector 145 and disengages from the second pallet 50. The second lifting mechanism 142 further lowers the support frame 141, thereby lowering the latch plate 144. The lowering of the first lifting assembly 13 allows the second and subsequent pallets 50 to return to the first conveying assembly 12. This process is repeated to further separate the second pallet 50 from the third and subsequent pallets 50. It is understood that when the latch plate 144 lowers, it can descend to the position corresponding to the second pallet 50 when separating the first pallet 50 from the second and subsequent pallets 50. Thus, when the second and subsequent pallets 50 return to the first conveying assembly 12, the latch plate 144 can precisely align with the third pallet 50, thereby reducing the time required to re-align with the pallets 50 and improving efficiency. It is understood that the position corresponding to pallet 50 refers to the position where the buckle plate 144 extends towards pallet 50 and can cooperate with pallet 50 to lift and support pallet 50. Specifically, for example, a secondary opening sensor can be used to sense whether pallets 50 are separated; a programmable logic controller or similar device can be used to control the operation of pallet feeding equipment 1. The telescopic mechanism 143 and the second lifting mechanism 142 both use cylinders, for example, which are compact, precise, and safe.
[0037] Another embodiment of this utility model is described below. At least two stacked pallets 50 are conveyed to a first conveying assembly 12, and further conveyed by the first conveying assembly 12 to a first lifting assembly 13. The at least two stacked pallets 50 are lifted by the first lifting assembly 13, and then a latching plate 144 is able to cooperate with the second pallet 50 from bottom to top to support it. At this time, the second and subsequent pallets 50 are supported by the latching plate 144, and the first pallet 50 is supported by the first lifting assembly 13. The first lifting assembly 13 descends, causing the first pallet 50 to fall onto the first conveying assembly 12, and is conveyed by the first conveying assembly 12 to the feeding transfer device 30. The first lifting assembly 13 then rises again to support the second and subsequent pallets 50, and then the latching plate 144 cooperates with the third pallet 50 to support the third and subsequent pallets 50. The first lifting assembly 13 descends, causing the second pallet 50 to fall onto the first conveying assembly 12, and is conveyed by the first conveying assembly 12 to the feeding transfer device 30. This process is repeated to convey all pallets 50 one by one to the feeding transfer device 30. It is understood that after the first lifting component 13 rises to support a second or more pallets 50, it can lower itself by, for example, the height of one pallet 50. This reduces the vertical movement of the latch plate 144, facilitating its interaction with the pallets 50 and improving efficiency. Since the latch plate 144 does not need to lift the stacked pallets 50 during the entire unpacking process, but only needs to support them, the stress requirements on the latch plate 144 and its bearing capacity are relatively low. The stacked pallets 50 are only lifted once during the entire unpacking process, and then lowered, significantly reducing the movement distance of the stacked pallets 50 and improving their stability. During the disassembly process, the buckle plate 144 does not need to descend to the conveying surface of the conveying tray 50 of the first conveying component 12, thus avoiding contact between the buckle plate 144 and other parts of the lifting component 14 and the first conveying component 12. This allows the lifting component 14 to be set close to the area through which the tray 50 passes, reducing the negative impact of the lever effect of the buckle plate 144 on the buckle plate 144 and the lifting component 14 when supporting the tray 50.
[0038] Understandably, when there is only one pallet 50, the first conveying component 12 can directly convey the pallet 50 to the feeding transfer device 30 without the need for the lifting component 14 and the first lifting component 13 to work.
[0039] The pallet feeding device 1 provided in this embodiment of the utility model conveys pallets 50 through a first conveying component 12, and raises and lowers pallets 50 through a first lifting component 13 and a lifting component 14. The three components work together to disassemble multiple stacked pallets 50, allowing the pallets 50 to be conveyed one by one by the first conveying component 12 to a feeding transfer device 30. The feeding transfer device 30 then transfers material 51 from or to pallets 50, thus achieving the transfer of material 51. By placing the first lifting component 13 within the first installation space 121 formed by the first conveying component 12, space is saved, and the first lifting component 13 is prevented from obstructing the conveying of pallets 50. Furthermore, the first lifting component 13, located below the pallets 50, provides more stable lifting of the pallets 50. By placing the second lifting mechanism 142 at the bottom of the support frame 141, the space above the buckle plate 144 occupied by the support frame 141 and the second lifting mechanism 142 is effectively reduced. This helps to increase the contact area between the buckle plate 144 and the pallet 50, allowing the buckle plate 144 to support the pallet 50 more stably and improving the stability of the lifting assembly 14. Placing the telescopic mechanism 143 on the side of the support frame 141 away from the first conveying assembly 12 reduces the space above the support frame 141 occupied by the telescopic assembly, preventing the telescopic mechanism 143 from obstructing the buckle plate 144. This further increases the contact area between the buckle plate 144 and the pallet 50, allowing the buckle plate 144 to support the pallet 50 more stably. The pallet feeding device 1 provided in this embodiment of the utility model can avoid setting components on the buckle plate 144, reduce interference with the movement of the buckle plate 144, thereby making the buckle plate 144 have a large range of motion and conveniently adapt to pallets 50 of different sizes; at the same time, the area of contact with the pallet 50 is also large, which can provide greater support force and help to support the pallet 50 more stably; further, the guide connector 145 is set to make the buckle plate 144 stably connected to the support frame 141, which can provide higher support force, increase the extension range of the buckle plate 144, and guide the buckle plate 144 to reduce the probability of the pallet 50 tipping over.
[0040] In some embodiments, see Figure 2 and Figure 3The first conveying assembly 12 is arranged along a first direction, and the support frame 141 is located on one side of the first conveying assembly 12 along a second direction. The guide connector 145 includes a second guide rail 1451 and a second slider 1452. The second guide rail 1451 is arranged along the second direction, and the second slider 1452 is located on the second guide rail 1451. The second slider 1452 is connected to the buckle plate 144, and the second guide rail 1451 is connected to the support frame 141. There are multiple second sliders 1452 and second guide rails 1451, and they are arranged in a one-to-one correspondence. The multiple second guide rails 1451 are arranged along the first direction, which is perpendicular to the second direction. The telescopic mechanism 143 drives the buckle plate 144, and then the buckle plate 144 moves along the second guide rail 1451 via the second slider 1452. In this way, the movement of the buckle plate 144 is smoother, and the second guide rail 1451 can guide the buckle plate 144 to avoid displacement of the buckle plate 144 in other directions, making the movement of the buckle plate 144 more stable. By setting multiple second guide rails 1451, the stability of the movement of the buckle plate 144 is further improved, and the supporting force of the buckle plate 144 is increased, effectively reducing the probability of the pallet 50 tipping over.
[0041] Specifically, see Figure 3 The buckle plate 144 includes a connecting body 1441 and a supporting part 1442. The connecting body 1441 is connected to a guide connector 145. The supporting part 1442 is located near the first conveying assembly 12 to cooperate with the pallet 50 to support the pallet 50. The supporting part 1442 is detachably connected to the connecting body 1441, which facilitates the replacement of supporting parts 1442 with different shapes to adapt to different types of pallets 50, thus improving applicability. For example, the supporting part 1442 has at least two protrusions on the side facing the first conveying assembly 12. When disassembling the pallet, the protrusions of the supporting part 1442 can be inserted between two pallets 50 and support the pallets 50 when they are raised. The presence of at least two protrusions also helps to make the support of the supporting part 1442 on the pallet 50 more even, effectively reducing the probability of the pallet 50 tipping over.
[0042] In some embodiments, see Figure 1 and Figure 2 The pallet feeding device 1 also includes a first mounting frame 11. The first conveying assembly 12 includes a first conveying mechanism 122 and a second conveying mechanism 123 disposed opposite to each other on both sides of the first mounting frame 11, forming a first installation space 121 between the first conveying mechanism 122 and the second conveying mechanism 123. In other words, the first lifting assembly 13 is disposed between the first conveying mechanism 122 and the second conveying mechanism 123, which allows for greater movement space for the first lifting assembly 13 and facilitates its disassembly and maintenance. Furthermore, the first conveying mechanism 122 and the second conveying mechanism 123, located on both sides of the first mounting frame 11, can simultaneously support and convey the pallet 50, making the conveying of the pallet 50 more stable.
[0043] Specifically, see Figure 4 The first lifting assembly 13 includes a first mounting component 131, a first lifting mechanism 132, a first support component 133, and a first guide rod 134. The first lifting mechanism 132 includes a first driving component 1321 and a first connecting component 1322. The first support component 133 can be connected to the first mounting frame 11 via the first mounting component 131. The first driving component 1321 is located on the bottom side of the first mounting component 131, and the first support component 133 is located on the top side of the first mounting component 131. The first connecting component 1322 passes through the first mounting component 131, and its two ends are respectively connected to the first driving component 1321 and the first support component 133. The first guide rod 134 is connected to the top side of the first mounting component 131 and is connected to the first support component 133. The first support member 133 can cooperate with the tray 50 to support the tray 50, so that the first drive member 1321 can drive the first connector 1322, thereby driving the first support member 133 to make the tray 50 move up and down.
[0044] By setting the first connecting member 1322, the first supporting member 133 and the first driving member 1321 are located on different sides of the first mounting member 131, thereby preventing the first driving member 1321 from affecting the movement of the first supporting member 133. Furthermore, the first mounting member 131 can also provide some isolation to the first driving member 1321, thereby reducing the impact of dust and volatile organic compounds generated by the first driving member 1321 on the material 51. By setting the first guide rod 134 to guide the movement of the first supporting member 133, the movement of the first supporting member 133 can be precise and stable, thus making the pallet 50 more stable when carried and moved by the first supporting member 133. Specifically, for example, two first guide rods 134 are set, with the two first guide rods 134 respectively located on both sides of the first connecting member 1322, thus making the movement of the first supporting member 133 more precise and stable. The first mounting member 131 is, for example, plate-shaped, which facilitates processing and installation, and also allows for the addition of the first lifting mechanism 132 and the first supporting member 133. The number of first support members 133 and first lifting mechanisms 132 are multiple and correspond one-to-one. Thus, multiple first support members 133 can simultaneously support the pallet 50, thereby further improving the stability of the pallet 50's movement.
[0045] In some embodiments, see Figures 1 to 3The first conveying assembly 12 includes multiple roller structures 124. The support frame 141 includes a first support portion 1411, a second support portion 1412, and two support members 1413. The first support portion 1411 is located on the side of the first mounting frame 11 facing the roller structures 124, and passes through the gap between any two adjacent roller structures 124. The second support portion 1412 is located on the side of the first mounting frame 11 away from the roller structures 124. The two support members 1413 are connected to the first support portion 1411 and the second support portion 1412, respectively, and are located at the top and bottom of the first support portion 1411. A guide connector 145 is provided on the support member 1413 located at the top of the first support portion 1411. The second lifting mechanism 142 is drivenly connected to the support member 1413 located at the bottom of the first support portion 1411. Thus, the first support portion 1411 and the second support portion 1412 are located on the inner and outer sides of the first mounting frame 11, which can improve the stability and load-bearing capacity of the support frame 141, thereby further improving the stability when moving the pallet 50. Simultaneously, the first support portion 1411 passes through the gaps, effectively utilizing space and reducing the impact on the transport of the pallet 50. Specifically, for example, the first support portion 1411 includes multiple support columns, which are respectively passed through the gaps between two adjacent roller structures 124. It can be understood that the support columns pass through different gaps. Furthermore, the multiple support columns can be interconnected to improve structural stability, further increase load-bearing capacity, and improve anti-overturning capability.
[0046] For some specific embodiments, see Figure 1 and Figure 2 The pallet feeding device 1 also includes a first mounting frame 11, with a first conveying assembly 12 mounted on the first mounting frame 11. The pallet unloading device 10 further includes two first guide rails 40 and two first sliders 41. The two first guide rails 40 are respectively arranged along a third direction on the first mounting frame 11 and are located below the first conveying assembly 12. The two first guide rails 40 are arranged on opposite sides of the second lifting mechanism 142, and the two first sliders 41 are correspondingly arranged on the two first guide rails 40 and respectively connected to the support frame 141. In this way, by setting the first guide rails 40 and the first sliders 41 to guide the support frame 141, the support frame 141 is made more stable and precise when moving, which helps to accurately move the buckle plate 144 to the designated position. Furthermore, since the support frame 141 is connected to the first sliders 41 on both sides, it also helps to reduce the probability of the support frame 141 tipping over. Furthermore, the two pairs of first guide rails 40 and first sliders 41 are arranged on both sides of the second lifting mechanism 142, so that they can be combined as a whole and installed on the first mounting frame 11 during installation, thereby reducing the difficulty of disassembly and assembly and facilitating maintenance.
[0047] In some embodiments, see Figure 5 and Figure 6 The material feeding and transfer device 30 includes a second mounting frame 31, a transfer component 32, a second conveying assembly 33, and a positioning assembly 34. The second conveying assembly 33 is mounted on the second mounting frame 31 along a first direction, the transfer component 32 is mounted on the second mounting frame 31, and the positioning assembly 34 is mounted on top of the second conveying assembly 33. The pallet 50 is conveyed by the first conveying assembly 12 to the second conveying assembly 33, and then by the second conveying assembly 33 to the positioning assembly 34. The positioning assembly 34 positions the pallet 50 so that the transfer component 32 can accurately remove or place materials 51 from or into the pallet 50. After the material 51 is transferred, the second conveying assembly 33 continues to convey the pallet 50 to the subsequent production line. Thus, through the cooperation of the second mounting frame 31, the transfer component 32, and the second conveying assembly 33, the transfer of materials 51 and the conveying of pallets 50 to the subsequent production line can be achieved.
[0048] Specifically, see Figure 5 and Figure 6The feeding and transferring device 30 also includes a third conveying component 35, a second lifting component 36, and a moving component 37. The third conveying component 35 is mounted on the second mounting frame 31 and located below the second conveying component 33. The height difference between the third conveying component 35 and the second conveying component 33 is greater than the height of the pallet 50. The second lifting component 36 partially passes through the third conveying component 35. The second conveying component 33 includes a third conveying mechanism 331 and a fourth conveying mechanism 332 located opposite each other on both sides of the second mounting frame 31. There are two positioning components 34, which are respectively located on the third conveying mechanism 331 and the fourth conveying mechanism 332. The moving component 37 is mounted on the second mounting frame 31 along the second direction and connected to the third conveying mechanism 331. It can be understood that the height of the pallet 50 refers to the dimension of the pallet 50 in the third direction. After the pallet 50 is positioned by the positioning component 34, the second lifting component 36 rises to support the pallet 50. After the transfer component 32 completes the transfer of material 51, the moving component 37 moves the third conveying mechanism 331 away from the fourth conveying mechanism 332, so that the gap between the third and fourth conveying mechanisms 331 can accommodate the pallet 50. At this point, the pallet 50 is completely supported by the second lifting component 36, which then descends, placing the pallet 50 on the third conveying component 35 for transport to the subsequent production line. The third conveying mechanism 331 is then moved by the moving mechanism to its pre-separation position. It can be understood that when the pallet 50 descends between the second and third conveying components 33 and does not interfere with the second conveying component 33, the third conveying mechanism 331 can be moved to its pre-separation position. Thus, the time it takes for pallet 50 to move out of the material 51 transfer station depends on the time it takes for pallet 50 to move vertically, that is, the time it takes to descend from the second conveying component 33 to the third conveying component 35. Since the vertical distance traveled by pallet 50 is short, the time it takes for pallet 50 to move out of the material 51 transfer station is short. After pallet 50 descends, the third conveying mechanism 331 and the fourth conveying mechanism 332 can immediately approach each other, allowing pallet 50 carrying material 51 to be immediately transported to the material 51 transfer station. This shortens the time when material is out of stock at the material 51 transfer station, reduces the waiting time for material 51 transfer, and makes the process of transferring material 51 to other production lines more continuous, improving transfer efficiency. Specifically, there are two moving components 37, connected to the third conveying mechanism 331 and the fourth conveying mechanism 332 respectively. This results in higher moving efficiency and helps to move pallet 50 to the third conveying component 35 more quickly. The moving component 37 can be, for example, a slider rail assembly, which is easy to install and occupies little space. In some specific embodiments, the second conveying component 33 and the third conveying component 35 are both rollers, for example, so that the length of the second conveying component 33 and the third conveying component 35 along the conveying line can be controlled by controlling the number of rollers.
[0049] In some embodiments, see Figures 5 to 8 The third conveying assembly 35 includes a plurality of third rollers 351 and a third drive member 352. The third rollers 351 extend along a first direction, and the plurality of third rollers 351 are arranged along a second direction. The third drive member 352 is drivenly connected to the plurality of third rollers 351. The second lifting assembly 36 includes a second mounting member 361, a second lifting mechanism 362, a second support member 363, and a second guide rod 364. The second lifting mechanism 362 includes a second drive member 3621 and a second connecting member 3622. The second mounting member 361 and the second mounting bracket 364 are connected to each other. A second driving member 3621 is located on the bottom side of the second mounting member 361, a second top support member 363 is located on the top side of the second mounting member 361, a second connecting member 3622 passes through the second mounting member 361, and both ends of the second connecting member 3622 are respectively connected to the second driving member 3621 and the second top support member 363, a second guide rod 364 is connected to the top side of the second mounting member 361 and to the second top support member 363, and the second top support member 363 passes through the gap between any two adjacent third rollers 351. The second top support member 363 can cooperate with the tray 50 to support the tray 50, so that the second driving member 3621 can drive the second connecting member 3622, thereby driving the second top support member 363 to move the tray 50 up and down.
[0050] By setting the second connecting member 3622, the second supporting member 363 and the second driving member 3621 are located on different sides of the second mounting member 361, thereby preventing the second driving member 3621 from affecting the movement of the second supporting member 363. Furthermore, the second mounting member 361 can also provide some isolation to the second driving member 3621, thereby reducing the impact of dust and volatile organic compounds generated by the second driving member 3621 on the material 51. By setting the second guide rod 364 to guide the movement of the second supporting member 363, the movement of the second supporting member 363 can be precise and stable, thus making the pallet 50 more stable when carried and moved by the second supporting member 363. Specifically, for example, two second guide rods 364 are set on both sides of the second connecting member 3622, making the movement of the second supporting member 363 more precise and stable. The second mounting member 361 is, for example, plate-shaped, which facilitates processing and installation, and also allows for the addition of the first lifting mechanism 132 and the first supporting member 133. The number of the second support member 363 and the second lifting mechanism 362 are multiple and correspond one-to-one. Thus, multiple second support members 363 can support the pallet 50 at the same time, thereby further improving the stability of the pallet 50 movement.
[0051] The second support member 363 passes through the gap between any two adjacent third rollers 351. In other words, the second support member 363 passes through the gap between adjacent third rollers 351 during lifting. Thus, there is no need to set up additional space to accommodate the second support member 363, which can reduce the modification of the third roller structure 124 and help save costs. The structure is compact and can be easily adapted to pallets 50 of different sizes without affecting the normal transportation of pallets 50.
[0052] In some specific embodiments, the first drive member 1321 and the second drive member 3621 are both cylinders, for example. Cylinders are precise in action, compact in structure, and safe and reliable.
[0053] Specifically, see Figure 1 , Figure 9 and Figure 10 The pallet feeding device 1 also includes a pallet stacking device 20. A third conveying assembly 35 is arranged along a second direction. The feeding and transfer device 30 also includes a pallet pushing assembly 38, located at the tail end of the third conveying assembly 35 along the second direction. The pallet pushing assembly 38 can move along a first direction. A pallet unpacking device 10 and a pallet stacking device 20 are respectively located at the head and tail of the third conveying assembly 35, and are situated on the same side of the third conveying assembly 35. After the material 51 is transferred, the pallet 50 is conveyed by the third conveying assembly 35 along the second direction to the tail end of the third conveying assembly 35. Then, the pallet pushing assembly 38 pushes the pallet 50 along the first direction to the pallet stacking device 20, where the pallet stacking device 20 stacks the pallet 50. Thus, the pallet feeding device 1 can completely realize pallet unpacking, material 51 conveying, and pallet stacking, achieving further integration, reducing costs, and saving space. Furthermore, the tray disassembly device 10 and the tray stacking device 20 are located on the same side of the third conveying assembly 35, which can further save the space occupied by the tray feeding device 1 and facilitate the installation of other equipment in the production line.
[0054] The stacking device 20 may employ the same structure as the unstacked device 10, but may be configured with different operating methods. A specific embodiment of the stacking device 20 is as follows: The first tray 50 is conveyed one by one by the third conveying mechanism 331 onto the first conveying assembly 12 of the stacking device 20, and further conveyed by the first conveying assembly 12 to a plurality of lifting assemblies 14 disposed on both sides of the first conveyor. The first lifting assembly 13 rises to support the first tray 50 and moves the first tray 50 to a position corresponding to the latch plate 144. The telescopic mechanism 143 drives the buckle plate 144 to extend and engage with the first pallet 50 to support it. The first lifting assembly 13 descends while the second lifting mechanism 142 raises the buckle plate 144, thus creating space for the second pallet 50. The second pallet 50 is conveyed between multiple lifting assemblies 14 positioned on both sides of the first conveyor. The first lifting assembly 13 rises, lifting the second pallet 50 and continuing to rise to simultaneously support both the first and second pallets 50. The buckle plate 144 retracts, and the second lifting mechanism 142 lowers the buckle plate 144 to correspond with the second pallet 50. The buckle plate 144 then extends and engages with the second pallet 50 to support both the first and second pallets 50. This process is repeated to stack the pallets 50. When there is only one pallet 50, it can be directly conveyed by the first conveying assembly 12 of the stacking device 20 to the production line after the stacking device 20.
[0055] For some specific embodiments, see Figure 9 and Figure 10 The pallet pushing assembly 38 includes a movable slide rail 381, a movable slider 382, a pusher plate 383, a pusher plate drive 384, and a pusher plate guide 385. The movable slider 382 is mounted on the movable slide rail 381 and is drivenly connected to the pusher plate drive 384. The pusher plate 383 is mounted on the movable slider 382. The movable slide rail 381 is arranged along a first direction. The pusher plate drive 384 pushes the movable slider 382 along the movable slide rail 381, thereby driving the pusher plate 383 to move along the first direction. The pusher plate 383 is at least partially located above the third conveying assembly 35, thus pushing the pallet 50 on the third conveying assembly 35 to move in the first direction to the stacking device 20 for stacking. The movable slider 382 is further connected to the pusher plate guide 385, which improves the stability of the movable slider 382's movement. For example, there are two pusher plate guides 385, respectively arranged on both sides of the movable slide rail 381 and respectively connected to the movable slide rail 381. The pusher component 383 is, for example, toothed and includes multiple protrusions that protrude from the third conveying component 35 to facilitate contact with the tray 50, thereby enabling the tray 50 to be moved.
