Description

Technical Field

[0001] The present invention relates to the technical field of feed tray transportation, in particular to a storage and transportation device for a feed tray. Background Art

[0002] Currently, feed products are generally produced using automated methods, whereby the feed is poured into woven bags and then packaged. Once the feed is produced, it is stacked onto pallets with the help of robotic arms and transported to storage or shipping areas.

[0003] Existing pallet conveying devices typically place multiple stacked empty pallets on a pallet holding device, push the bottom pallet out onto a conveyor chain, and then move it along the conveyor chain to the bottom of a robotic arm to stack the feed products. Because a single pallet can hold a large number of feed products and is heavy, iron or steel pallets are typically used. As multiple stacked empty pallets are heavy, simply pushing the bottom pallet out places significant stress on the pushing device, making it difficult to push the pallet out. This in turn leads to low pallet removal efficiency and frequent pallet jamming, significantly impacting the reliable stacking of feed products. Summary of the Invention

[0099] The following describes the specific implementation of the embodiment of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0100] Figure 1 Schematic diagram of the structure of a storage and transportation device for feed trays according to one embodiment of the present invention. Figure 1 In the embodiment, the storage and transportation device may include a transportation box 3, two partitions 1, a transportation component, a pallet support seat, a lifting component and two switching control components. Specifically, the transportation box 3 may include a transportation opening.

[0101] The top of the transport box 3 is open, and the side wall of the transport box 3 is provided with a transport opening. Two partitions 1 are arranged in parallel at the tops of the two opposite sides of the transport box 3, and one of the partitions 1 is located on the same side as the transport opening. The transport component is arranged inside the transport box 3, and one end of the transport component extends out of the transport box 3 along the transport opening, and is used to transport the pallet inside the transport box 3 out for stacking feed. The pallet support seat is arranged inside the transport box 3, and the side wall of the pallet support seat is slidably connected to the inner wall of the transport box 3. The jacking component is arranged at the inner bottom of the transport box 3, and is used to drive the pallet support seat to rise and fall. Two switching components are arranged at the inner bottom of the transport box 3, and are used to drive the pallet support seat to rise and fall. Two switching control components are arranged in parallel, and each switching control component is located at the same end of the two partitions 1, and is used to separate the bottommost pallet and the second pallet from the bottom to the top.

[0102] When pallets of feed products need to be transported, multiple stacked empty pallets need to be placed on the pallet support seat inside the transport box 3 to support the multiple empty pallets. The control drive switching control component is activated to separate the bottom pallet and the second pallet from the bottom to the top. The second pallet from the bottom to the top is limited and supported, and then all pallets above it are supported synchronously. The jacking component is then activated. The jacking component controls the pallet support seat to drive the bottom pallet to descend. As the bottom pallet gradually contacts the transport component during descent, and the bottom pallet and the pallet support seat are separated from each other. The transport component drives the bottom pallet out of the transport box 3 along the transport opening until it reaches the position where the feed products are to be stacked, thereby achieving the purpose of transporting the pallets. After the transport component outputs the pallet from the interior of the transport box 3, the jacking component drives the pallet support seat to rise and reset. The two switching control components move the second pallet from the bottom to the inside of the pallet support seat, and then drive the second pallet from the bottom to the top and the third pallet from the bottom to separate, and so on.

[0103] The traditional pallet conveying device generally places multiple stacked empty pallets on a pallet holding device, pushes the bottom pallet out to the conveyor chain, and moves with the conveyor chain to the bottom of the robotic arm to cooperate with the stacking of feed products. However, this method of only relying on pushing to remove the bottom pallet is prone to the situation where the pallet gets stuck, and for heavier pallets such as iron, it will increase the stress on the ejection device, affecting its removal efficiency. In this embodiment of the present invention, a switching control component is used to drive the bottom pallet and the second pallet from the bottom to the top to separate, which can facilitate the transport component to remove the pallet, that is, improve the convenience and reliability of pallet removal, avoid the occurrence of pallet jamming, and improve the efficiency of pallet transportation. In addition, the structure of the transport box 3 and the two partitions 1 can facilitate the stacking of pallets, and can also limit the placement position of the pallets so that the pallets can enter the interior of the pallet support seat one by one.

[0104] In this embodiment of the invention, Figure 1 and Figure 3 As shown, the tray support seat may include two L-shaped plates 18, two connecting plates 44 and two limiting protruding plates 17. Specifically, the L-shaped plate 18 may include a first evacuation notch 19.

[0105] Two L-shaped plates 18 are positioned opposite each other, one adjacent to each of the two switch control assemblies. The sidewalls of the two L-shaped plates 18 are slidably connected to the inner wall of the transport box 3. Two first clearance notches 19 are defined at the top of each L-shaped plate 18. Two connecting plates 44 are positioned parallel to each other, with each connecting plate 44's two ends connected to the top of the same end of the two L-shaped plates 18. Two stopper protrusions 17 are positioned at the top of each L-shaped plate 18, facing away from each other.

[0106] When multiple pallets need to be stacked, they are placed downward from above the two L-shaped plates 18. The opposing inner walls of the two L-shaped plates 18 securely restrain the pallets. The two connecting plates 44 connect the two L-shaped plates 18 into a single unit, allowing them to rise and fall synchronously, further enhancing the stability of the pallets during the lifting process. The two limiting protrusions 17 facilitate reliable connection with the switch control assembly, thereby facilitating effective control of the switch control assembly.

[0107] In this embodiment of the invention, Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, the switching control assembly may include a long plate body 9, a first cavity 24, two limit blocks 16, two lifting assemblies 6, a limit assembly and multiple fixing assemblies.

[0108] The two ends of the long plate body 9 extend to the same end of the two partitions 1, and the first cavity 24 is opened inside the long plate body 9. Two limit blocks 16 are arranged in parallel inside the first cavity 24, and one end of the two limit blocks 16 moves through the long plate body 9 and approaches the two first clearance slots 19. Two lifting assemblies 6 are respectively arranged at the same end of the two partitions 1, and are used to drive the long plate body 9 to rise and fall. The limit assembly is arranged inside the first cavity 24, and is used to push the two limit blocks 16 to move and limit the second pallet from the bottom to the top when the long plate body 9 is at the top to separate the bottom pallet and the second pallet from the bottom to the top. Multiple fixing assemblies are arranged on the top of the transport box 3, and are used to fix the limit protrusion 17 when the limit protrusion 17 is at the top.

[0109] When it is necessary to separate the bottom pallet and the second pallet from the bottom, the limiting protrusion 17 is located at the top, that is, at a position that can support and store the bottom pallet, and multiple fixing components fix the pallet support seat by fixing the limiting protrusion 17. The two lifting components 6 are started, driving the two long plates 9 to rise, and the two long plates 9 drive the corresponding limiting blocks 16 to rise. When the two long plates 9 rise to the top, that is, the position of the side wall of the second pallet from the bottom, the limiting component is driven to push the two limiting blocks 16 to move, so that the ends of the two limiting blocks 16 move to the inside of the second pallet from the bottom, so as to achieve the limiting fixation of the second pallet from the bottom, and then drive the lifting component to start, so as to achieve the separation of the bottom pallet and the second pallet from the bottom. The method of using the lifting component 6 and the limiting component to separate the two bottom pallets can make the trays more stable and flexible, without causing stress on the transport components, without affecting each other, and with better coordination.

[0110] In this embodiment of the invention, Figure 8 and Figure 9 As shown, the fixing assembly may include an inverted L-shaped fixing block 10, a limiting plate 37, two rotating plates 45, a rotating shaft 38, a pushing assembly, and two second evacuation slots 29. Specifically, the inverted L-shaped fixing block 10 may include a second cavity 30.

[0111] An inverted L-shaped fixing block 10 is disposed at the top of the transport box 3, and a second cavity 30 is defined within the inverted L-shaped fixing block 10. A limiting plate 37 is disposed within the angle of the inverted L-shaped fixing block 10. One end of the limiting plate 37 movably passes through the vertical section of the inverted L-shaped fixing block 10 and extends into the second cavity 30. The horizontal section of the inverted L-shaped fixing block 10 and the limiting plate 37 cooperate to limit and fix the end of the limiting protrusion 17 away from the L-shaped plate 18. Two rotating plates 45 are disposed parallel to each other within the second cavity 30, and the bottom ends of the two rotating plates 45 are rotatably connected to one end of the limiting plate 37. A rotating shaft 38 is fixedly provided through the two rotating plates 45, and both ends of the rotating shaft 38 are rotatably connected to the inner wall of the second cavity 30. A pushing assembly is disposed within the elongated plate body 9 and is used to push the top ends of the two rotating plates 45 to drive the limiting plate 37 to move into the second cavity 30. Two second easing slots 29 are formed inside the inverted L-shaped fixing block 10 and communicate with the second cavity 30 for easing engagement when the two rotating plates 45 rotate.

[0112] When the lowermost tray needs to be released from the restraining position of the retaining plate 17, that is, when the lowermost tray needs to be separated from the second tray from the bottom, the long plate 9 is located at the side wall of the second tray from the bottom. The driving assembly is activated, pushing the top ends of the two rotating plates 45, causing them to rotate and enter the corresponding second clearance slots 29. At the same time, as the retaining plates 37 move through the vertical section of the inverted L-shaped fixing block 10, the bottom ends of the two rotating plates 45 drive the retaining plates 37 to gradually move into the second cavity 30, thereby releasing the restraint of the retaining plate 17. At this time, the tray support seat can be lowered under the drive of the lifting assembly, allowing the lowermost tray to separate from the second tray from the bottom. Using this driving method, the long plate 9 can simultaneously release the restraint of the retaining plate 17 after moving to the side wall of the second tray from the bottom and securing the second tray from the bottom, thereby improving the reliability and flexibility of pallet transportation and enhancing coordination.

[0113] In this embodiment of the present invention, considering the reliability of the limit plate 37 in moving into the second cavity 30, a slide is provided on the side of the rotating plate 45 close to the limit plate 37. The slide can slide along the extension direction of the limit plate 37, and the slide is hinged to one end of the rotating plate 45 located inside the second cavity 30.

[0114] In this embodiment of the present invention, to facilitate securing the limiting plate 17 after its ascent and resetting, the bottom of the limiting plate 37 is designed as a curved surface, and the rotating plate 45 is connected to the inner wall of the second cavity 30 via a spring. As the limiting plate 17 ascends, the limiting plate 37 first contacts the curved surface, pushing it into the second cavity 30, causing the spring to stretch. Until the limiting plate 17 contacts the bottom of the horizontal section of the inverted L-shaped fixing block 10, the limiting plate 37, under the action of the rotating plate 45 and the spring, returns to its original position and extends, cooperating with the horizontal section of the inverted L-shaped fixing block 10 to support the limiting plate 17.

[0115] In this embodiment of the invention, Figure 8 and Figure 9 As shown, the pushing assembly may include a third cavity 43, two push pins 35, a first screw 34, a first threaded collar 33, two first connecting rods 36, two third relief slots 11, a first bevel gear 32, a second bevel gear 31, a rotating shaft 23 and two rotating assemblies.

[0116] The third cavity 43 is defined within the elongated plate 9. Two push pins 35 are positioned parallel to each other within the third cavity 43. One end of each push pin 35 flexibly passes through the elongated plate 9 and extends to the outside of the elongated plate 9. One end of the first screw 34 is rotatably connected to the inner wall of the third cavity 43. The first threaded collar 33 is threadedly mounted on the outside of the first screw 34. One end of each first connecting rod 36 is connected to the first threaded collar 33, and the other end of each first connecting rod 36 is connected to the other end of each push pin 35. Two third clearance notches 11 are defined on the side of the inverted L-shaped fixing block 10 near the elongated plate 9 and communicate with the second cavity 30. The two push pins 35 are designed to extend into and cooperate with the third clearance notches 11 to rotate the two rotating plates 45. The first bevel gear 32 is located at the other end of the first screw 34. The second bevel gear 31 is conically connected to the first bevel gear 32. The rotating shaft 23 flexibly extends through the second bevel gear 31, with its ends extending out of the elongated plate 9. The two rotating assemblies are respectively arranged at the two ends of the long plate body 9, and are used to drive the rotating shaft 23 to rotate when the lifting assembly 6 is started.

[0117] Before the lowermost tray needs to be released from the retaining plate 17, that is, before the lowermost tray is separated from the second tray from the bottom, the lifting assembly 6 drives the elongated plate 9 upward. During the ascending process, the elongated plate 9 drives the rotating shaft 23 to rotate. The rotating shaft 23, via the second bevel gear 31, drives the first bevel gear 32 to rotate, thereby driving the first screw 34 to rotate. The rotation of the first threaded rod 34 drives the first threaded collar 33 to move, simultaneously driving the two push pins 35 to move, so that the push pins 35 gradually enter the interior of the second cavity 30 along the two third clearance grooves 11 and push near the top of the two rotating plates 45. This allows the two rotating plates 45 to drive the retaining plates 37 to be retracted into the interior of the second cavity 30, thereby releasing the retaining plate 17. That is, after the elongated plate 9 moves to the side wall of the second tray from the bottom and secures the second tray from the bottom, it simultaneously releases the retaining plate 17. This improves the reliability and flexibility of pallet transportation, enhances coordination, and has a simple and reliable structure. On the contrary, when the rotating shaft 23 rotates in the reverse direction, the two push pins 35 are driven to be gradually retracted into the third cavity 43 .

[0118] In this embodiment of the invention, Figure 2 、 Figure 5 and Figure 7 As shown, the rotating assembly may include a rotating box 8, a first gear 22, a second gear 21 and a rack 7. Specifically, the rotating box 8 may include a fourth relief notch 20.

[0119] A rotating box 8 is mounted at the end of the elongated plate 9. One end of a rotating shaft 23 extends into the interior of the rotating box 8 and is rotatably connected to the inner wall of the rotating box 8. A fourth clearance notch 20 is defined on the side of the rotating box 8 proximal to the partition 1. A first gear 22 is fixedly mounted on the outer side of the rotating shaft 23, while a second gear 21 is rotatably mounted within the interior of the rotating shaft 23. A rack 7 is mounted on the partition 1 and extends into the interior of the fourth clearance notch 20. The portion of the second gear 21 that meshes with the first gear 22 meshes with the rack 7.

[0120] When the long plate 9 is driven to rise, the rotating box 8 is controlled to rise. During the rising process, the rotating box 8 drives the second gear 21 to rotate through the meshing action of the second gear 21 and the rack 7. The second gear 21 drives the first gear 22 to rotate, thereby driving the rotating shaft 23 to rotate during the process of the long plate 9 being raised or lowered.

[0121] In this embodiment of the present invention, the specific structure of the lifting assembly includes but is not limited to a linear motor, etc. Specifically, the output end of the linear motor is connected to the side wall of the rotating box 8.

[0122] In this embodiment of the invention, Figure 4 and Figure 6 As shown, the limiting assembly may include two wedge blocks 28 , a driving block 27 , a second connecting rod 25 and a driving cylinder 26 .

[0123] The wedge surfaces of the two wedge blocks 28 are arranged to fit relative to each other, and the two wedge blocks 28 are slidably connected to the inner wall of the first cavity 24. A driving block 27 is positioned between the two wedge blocks 28, with the two edges of one side of the driving block 27 respectively fitting against the two wedge surfaces. One end of the two second connecting rods 25 is hinged to the wedge blocks 28, and the other end of the second connecting rods 25 is hinged to the side wall of the limit block 16. A driving cylinder 26 is positioned within the first cavity 24, and the interior of the driving cylinder 26 is connected to the other side of the driving block 27.

[0124] When the second pallet (from bottom to top) needs to be secured, that is, when the long plate 9 moves to the side wall of the second pallet (from bottom to top), the drive cylinder 26 is activated, pushing the drive block 27 to move. The drive block 27 pushes the two wedge blocks 28 away from each other, which in turn moves one end of the two second connecting rods 25 away from each other. As the two second connecting rods 25 move away from each other, they impart a tilting force to the two stoppers 16, allowing them to extend out of the first cavity 24 and into the second pallet (from bottom to top), reliably securing it. This positioning method also offers excellent synergy and high reliability.

[0125] In this embodiment of the invention, Figure 3 and Figure 10As shown, the lifting assembly may include two top plates 42, four slide grooves 39, four sliders 40, two third connecting rods 5, four fourth connecting rods 41 and a driving assembly.

[0126] The two top plates 42 are arranged in parallel inside the transport box 3 and are respectively located below the two L-shaped plates 18. Four chutes 39 are opened at the inner top of the transport box 3 and are located two by two below the two top plates 42. Four sliders 40 are respectively slidably arranged inside the four chutes 39, and the two third connecting rods 5 are arranged in parallel, and the two ends of each third connecting rod 5 are respectively connected to the two sliders 40 opposite to each other below the two top plates 42. One end of the four fourth connecting rods 41 is hinged to the corresponding slider 40, and the other end of the four fourth connecting rods 41 is hinged to the bottom of the corresponding top plate 42. The two fourth connecting rods 41 of the same top plate 42 are in an eight-shaped shape. The driving component is arranged at the inner bottom of the transport box 3, and is used to drive the two third connecting rods 5 to move closer to or away from each other.

[0127] After the bottom tray separates from the second tray from below, the drive assembly activates, driving the two third connecting rods 5 away from each other, which in turn drives the corresponding sliders 40 to slide along the inside of the corresponding chute 39. This means that one end of the two fourth connecting rods 41 below the same top plate 42 moves away from each other, causing the two top plates 42 to drive the two L-shaped plates 18 downward. As the two L-shaped plates 18 descend, the bottom of the tray inside them gradually contacts the transport assembly and, driven by the transport assembly, moves out of the interior of the transport box 3. Conversely, driving the two third connecting rods 5 toward each other can drive the two L-shaped plates 18 upward. This structure is simple, reliable, and more stable, making it easier to raise and lower the tray support.

[0128] In this embodiment of the present invention, the specific structure of the transport component includes but is not limited to two parallel belt lines 4 or two parallel conveyor chains, etc.

[0129] In this embodiment of the invention, Figure 3 As shown, the driving assembly may include a groove 15 , two second screws 14 , two second threaded collars 13 and a driving motor 12 .

[0130] A groove 15 is defined within the inner bottom of the transport box 3. Two second screws 14 are disposed within the groove 15. The two second screws 14 rotate in opposite directions, and their opposite ends are fixedly connected. Two second threaded collars 13 are respectively threadedly mounted on the outer sides of the two second screws 14 and are respectively fixedly connected to the two third connecting rods 5. A drive motor 12 is disposed within the inner wall of the groove 15. The output end of the drive motor 12 is connected to the end of one of the second screws 14 that is away from the other second screw 14.

[0131] When the two third connecting rods 5 need to be driven closer to or farther from each other, the driving motor 12 is started to rotate the two second screw rods 14. Since the two second screw rods 14 rotate in opposite directions, the two third connecting rods 5 can be driven closer to or farther from each other.

[0132] In this embodiment of the invention, Figure 1 As shown, the storage and transportation device may further include a plurality of guide plates 2. Specifically, the guide plates 2 are provided on the opposite side walls of the two partitions 1 for guiding the pallets when the pallets are placed so that the pallets can be reliably stacked.

[0133] Through the above technical solution, the storage and transportation device for feed pallets provided by the present invention can realize the storage of empty pallets by placing multiple stacked empty pallets on the pallet support seat; the drive switching control component is started, so that the bottom pallet and the second pallet from the bottom to the top are separated from each other, and the jacking component drives the pallet support seat to drive the bottom pallet to descend and contact the transportation component, and the transportation component drives the bottom pallet to move out of the transportation box 3 along the transportation opening and reach the position to be used; the switching control component is used to control the separation of the bottom pallet and the second pallet from the bottom to the top, on the one hand, it can ensure the stability of the storage of multiple empty pallets, and on the other hand, it can also improve the convenience and reliability of removing the bottom pallet, avoid the occurrence of pallet jamming, and is more intelligent and convenient.
