[0064] Explanation of reference numerals

[0065] Detailed description of specific embodiments

[0066] The following will describe in detail the specific embodiments of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0067] Figure 1 A schematic structural view of a stacking and transporting device for feed trays according to an embodiment of the present invention; Figure 2 A side view of a stacking and transporting device for feed trays according to an embodiment of the present invention. In Figure 1 and Figure 2 the stacking and transporting device may include a stacking box 8, four support columns 19, two baffles 1, a tray stacking component, and two calibration components.

[0068] The top of the stacking box 8 is open, and the four support columns 19 are respectively arranged at the four corners of the top of the stacking box 8, with two adjacent support columns 19 as a group. The two baffles 1 are arranged in parallel, and the two ends of the two baffles 1 are respectively connected to the opposite ends of the two support columns 19 in the corresponding group. The tray stacking component is arranged between the two baffles 1 and is used to move the trays from near the side wall of the stacking box 8 to near the top of the support columns 19. The two calibration components are respectively arranged on the inner walls of the two baffles 1 and are used to cooperate with the tray stacking component and calibrate the stacking position of the trays.

[0069] When it is necessary to stack pallets, the forklift can place some stacked pallets inside the stacking box 8. When it is necessary to stack pallets above some stacked pallets, start the pallet stacking component, move it to near the side wall of the stacking box 8, then convey it to near the top of the support column 19 through the pallet stacking component, and finally calibrate and position the pallet through two calibration components, so that multiple pallets can be reliably and accurately stacked on the top of some stacked pallets.

[0070] In the stacking device of traditional feed products, tools such as forklifts are needed to stack pallets. The forklift has requirements for the placement height of pallets, and the height it can rise by itself is limited. Therefore, the stacking height of pallets is limited, and it is necessary to stack pallets frequently. If the stacking is not timely, it is easy to affect the production efficiency of feed products, and then cause a lot of inconvenience. In this embodiment of the present invention, by using the cooperation of the pallet stacking component and the calibration component, the purpose of transporting pallets from low places to high places can be achieved, and at the same time, the frequency of pallet stacking is reduced, ensuring the conveying efficiency of feed products; the calibration component can calibrate and stack the pallets at high places to ensure the reliability and accuracy of pallet stacking.

[0071] In this embodiment of the present invention, as Figure 1 and Figure 2 shown, the pallet stacking component may include a first U-shaped plate 6, a second U-shaped plate 3, a limiting component, a driving component, a guiding component, and a lifting component 5.

[0072] The first U-shaped plate 6 is arranged on one side of two groups of support columns 19 perpendicular to the two baffles 1, and the opening of the first U-shaped plate 6 faces upward. The second U-shaped plate 3 is arranged between the two groups of support columns 19, and the opening of the second U-shaped plate 3 faces the first U-shaped plate 6. The limiting component is arranged at the bottom of the second U-shaped plate 3 and is used to support multiple pallets. The driving component is arranged on the two support columns 19 far from the first U-shaped plate 6 and is used to push the second U-shaped plate 3 to move. The guiding component is arranged on the opposite inner walls of the two baffles 1 and is used to communicate with the inside of the first U-shaped plate 6, so that the second U-shaped plate 3 can move into or out of the inside of the first U-shaped plate 6 under the drive of the driving component. The lifting component 5 is arranged on the two support columns 19 close to the first U-shaped plate 6 and is used to control the lifting of the first U-shaped plate 6.

[0073] When it is necessary to stack the trays at a high place, the driving assembly is activated. Cooperating with the guiding assembly, it pushes the second U-shaped plate 3 to move inside the first U-shaped plate 6. Then, the lifting assembly 5 is driven to start and place the first U-shaped plate 6 near the side wall of the stacking box 8 placed below. The forklift places the stacked trays on the second U-shaped plate 3. The limiting assembly supports the multiple stacked trays. Then, it is driven by the lifting assembly 5 to rise until it is flush with the lower end of the second U-shaped plate 3. The driving assembly is activated to push the second U-shaped plate 3 to move back to its original position between the two baffles 1. The calibration assembly calibrates the position of the second U-shaped plate 3. After the calibration is completed, the limiting assembly disengages from the limitation of the trays, so that the multiple trays on it fall a small height and are stacked on the already stacked partial trays, thereby realizing the stacking height of the trays. With this structure, on the one hand, it does not affect the stable stacking of the trays inside the stacking box 8, and on the other hand, it can also ensure the reliable stacking of the trays at a high place.

[0074] In this embodiment of the present invention, for the specific structure of the lifting assembly 5, it includes but is not limited to Figure 1 the linear motor module shown.

[0075] In this embodiment of the present invention, as Figure 2 and Figure 4 shown, the limiting assembly may include two first rotating shafts, two limiting plates 2, two first bevel gears 17, two second bevel gears 16, a second rotating shaft 12, two support plates 18, and a rotating assembly.

[0076] The two first rotating shafts are respectively rotatably arranged at the two parallel bottom ends of the second U-shaped plate 3. One end of each of the two limiting plates 2 is fixedly sleeved outside the corresponding first rotating shaft. The two first bevel gears 17 are arranged on the side of the second U-shaped plate 3 away from its opening and are respectively fixedly connected to one end of each of the two first rotating shafts. The two second bevel gears 16 are symmetrically arranged and are respectively meshed with the two first bevel gears 17. The second rotating shaft 12 is fixedly penetrated through the two second bevel gears 16. The two support plates 18 are arranged at both ends of the second rotating shaft 12 and are connected to the second U-shaped plate 3. The two ends of the second rotating shaft 12 are respectively rotatably connected to the two support plates 18. The rotating assembly is connected to the second rotating shaft 12 and is used to drive the second rotating shaft 12 to rotate.

[0077] When it is necessary to drive the support and limitation of the trays, the rotating assembly drives the second rotating shaft 12 to rotate. The second rotating shaft 12 drives the two first bevel gears 17 and the limiting plates 2 to rotate through the two second bevel gears 16. Since the two second bevel gears 16 are symmetrically arranged, the two limiting plates 2 rotate in opposite directions to the horizontal, and thus the support and fixation of the trays can be realized. Conversely, when the rotating assembly rotates in the reverse direction, it can drive the two limiting plates 2 to rotate to the vertical state, and the trays lose support and can then fall and be stacked. With this support method, it can not only stably support the trays but also facilitate the disengagement of the support for the trays, which is more convenient and fast.

[0078] In this embodiment of the present invention, the specific structure of the rotating assembly can be various forms known to those skilled in the art. For example, the motor drives the driven gear outside the second rotating shaft 12 through the main gear, or the motor bevel gear drives the bevel gear outside the second rotating shaft 12, etc. However, in a preferred example of the present invention, considering the reliability and flexibility of the rotation of the second rotating shaft 12, the specific structure of the rotating assembly can include a rotating box 13, a driving motor, a third bevel gear, and a fourth bevel gear. Specifically, the rotating box 13 is arranged on the side wall of the second U-shaped plate 3, and the second rotating shaft 12 movably passes through the rotating box 13. The driving motor is arranged inside the rotating box 13, the third bevel gear is arranged inside the rotating box 13 and is fixedly sleeved outside the second rotating shaft 12, and the fourth bevel gear is arranged at the output end of the driving motor and is meshed with the third bevel gear.

[0079] In this embodiment of the present invention, as Figure 2 , Figure 3 and Figure 4 described, the driving assembly can include a first driving cylinder 10, a first driving plate 11, a second driving cylinder 7, and a second driving plate 14.

[0080] The first driving cylinder 10 is arranged on two support columns 19 far away from the first U-shaped plate 6, and the first driving plate 11 is arranged at the output end of the first driving cylinder 10 and is used to fit against the side wall of the second U-shaped plate 3 far away from its opening. The second driving cylinder 7 is arranged on the first U-shaped plate 6 far away from the support column 19. Therefore, the second driving plate 14 is arranged at the output end of the second driving cylinder 7 and is used to fit against the side wall of the second U-shaped plate 3 close to its opening.

[0081] When it is necessary to stack trays on the second U-shaped plate 3, the first driving cylinder 10 is started and the second U-shaped plate 3 is pushed by the first driving plate 11 to move along the guiding assembly to the first U-shaped plate 6. After the trays are stacked on the second U-shaped plate 3, the second driving cylinder 7 is started, and the second U-shaped plate 3 is pushed by the second driving plate 14 between the two baffles 1 and is calibrated and positioned with the calibration assembly for the second U-shaped plate 3 and the trays inside it.

[0082] In this embodiment of the present invention, as Figure 3 shown, in order to improve the reliability and stability of fixing the second U-shaped plate 3 on the first U-shaped plate 6, an electromagnetic block 15 is embedded on the side of the second driving plate 14 far away from the second driving cylinder 7, and a metal or magnetic block cooperating with the electromagnetic block 15 is embedded at the open end of the second U-shaped plate 3. Specifically, the electromagnetic block 15 is connected and controlled by a conductive assembly. When the second U-shaped plate 3 moves closer to the first U-shaped plate 6, the electromagnetic block 15 is started; when the second U-shaped plate 3 moves away from the first U-shaped plate 6, the electromagnetic block 15 is closed.

[0083] In this embodiment of the present invention, as Figures 6 to 8 shown, the guiding assembly may include a guide plate 20, a plurality of rollers 28, a plurality of connecting blocks 27, and a second guide groove 9. Specifically, the guide plate 20 may include a first guide groove 26.

[0084] The guide plate 20 is arranged on two support columns 19 of one group. A first guide groove 26 is formed on the side of the guide plate 20 close to the second U-shaped plate 3. A plurality of rollers 28 are rotatably arranged inside the first guide groove 26. A plurality of connecting blocks 27 are arranged on the side walls of the second U-shaped plate 3 and are respectively rotatably connected to the corresponding rollers 28. The second guide groove 9 is formed on the inner wall of the first U-shaped plate 6 and is used to cooperate with the first guide groove 26 to conduct.

[0085] When the driving assembly pushes the second U-shaped plate 3 to move, the plurality of rollers 28 can roll along the inside of the first guide groove 26. At the same time, since the first guide groove 26 and the second guide groove 9 can conduct, the second U-shaped plate 3 can move between the first U-shaped plate 3 and the two baffles 1 very conveniently. With this guiding method, it is more flexible and smooth.

[0086] In this embodiment of the present invention, as Figures 6 to 8 shown, the calibration assembly may include two calibration openings 21, two calibration plates 22, two telescopic slots, a calibration slot 29, two magnetic blocks, and a control assembly. Specifically, the baffle 1 may include a chute 26. The telescopic slot may include a calibration rod and a spring. The calibration slot 29 may include an electromagnetic strip 30.

[0087] Two calibration openings 21 are symmetrically formed on the guide plate 20. Two calibration plates 22 are respectively movably arranged inside the two calibration openings 21. One end of the two calibration plates 22 close to the corresponding baffle 1 extends to the corresponding baffle 1 and is slidably connected to the chute 26 on the corresponding baffle 1. Two telescopic slots are respectively formed at one end of the two calibration plates 22 away from the corresponding baffle 1. A calibration rod is movably arranged inside the two telescopic slots, and the calibration rod is connected to the inner wall of the corresponding telescopic slot through a spring. The calibration slot 29 is formed on the side of the second U-shaped plate 3 close to the calibration opening 21. An electromagnetic strip 30 is embedded inside the calibration slot 29, and the electromagnetic strip 30 is connected to the wire assembly. Two magnetic blocks are respectively arranged at one end of the two calibration rods close to the calibration slot 29. The control assembly is arranged on the baffle 1 and is used to drive the two calibration plates 22 to approach or move away from each other.

[0088] When the second driving cylinder 7 pushes the second U-shaped plate 3 into the space between the two baffles 1 through the second driving plate 14, the two calibration plates 22 are within the range of the calibration groove 29. The conductive component is activated, so that the electromagnetic strip 30 drives, and then the calibration rod extends out of the telescopic groove and enters the interior of the calibration groove 29 under the adsorption of the magnet block and the electromagnetic strip 30, and the spring is stretched. The drive control component is activated and drives the two calibration plates 22 to move away from each other along the corresponding calibration openings 21. If the second U-shaped plate 3 has not reached the position for stacking the stacking tray, one of the calibration plates 22 first contacts the inner wall of the calibration groove 29 and pushes the second U-shaped plate 3 to move. So that the two calibration plates 22 respectively abut against the two opposite inner walls of the calibration groove 29, and then the second U-shaped plate 3 can reach the position of the stacking tray, so as to realize the precise calibration of the second U-shaped plate 3 and the tray. This calibration method is accurate and reliable, and the structure is simple and stable.

[0089] In this embodiment of the present invention, as Figures 6 to 8 shown, the control component may include a screw rod 24, a frame plate 4, a control motor 25, a threaded collar 31 and two push rods 23.

[0090] The screw rod 24 is arranged between the guide plate 20 and the baffle 1. One end of the screw rod 24 is rotatably connected to the guide plate 20, and the other end of the screw rod 24 is threadedly passed through the baffle 1. The frame plate 4 is arranged on the side of the baffle 1 away from the guide plate 20. The control motor 25 is arranged on the frame plate 4, and the output end of the control motor 25 is connected to the other end of the screw rod 24. The threaded collar 31 is threadedly sleeved on the outer side of the screw rod 24. The two push rods 23 are symmetrically arranged on the outer side of the threaded collar 31. One end of the push rod 23 is hinged to the threaded collar 31, and the other end of the push rod 23 is hinged to the corresponding calibration plate 22.

[0091] When it is necessary to push the two calibration plates 22 away from or close to each other, the control motor 25 is activated. The control motor 25 drives the screw rod 24 to rotate, and the threaded collar 31 moves horizontally along the guide plate 20 on the screw rod 24, and then drives the two calibration plates 22 to approach or move away from each other through the two push rods 23.

[0092] Through the above technical solutions, the starting stacking and transporting device of the feed tray provided by the present invention can start the tray stacking component to stack the trays at the same height on the side wall of the stacking box 8 near the top of the support column 19, that is, the number of stacked trays is increased, and then the frequency of tray stacking is reduced, making the tray conveying more reliable and ensuring the production efficiency of the feed products; at the same time, the calibration component can calibrate the trays on the tray stacking component, so that the trays at a high place are accurately stacked on the stacked trays, improving the reliability and accuracy of the tray stacking.

[0093] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.
