Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-8 As shown, a pallet placement device includes a support frame 10, in which multiple pallets 20 are evenly placed from top to bottom within the support frame 10; a support mechanism 30 for providing horizontal support for the pallets 20 evenly placed from top to bottom within the support frame 10; and a lifting mechanism 40 for cooperating with the support mechanism 30 to lift the pallets 20 onto the empty support mechanism 30 at the top of the support frame 10 for storage, wherein the storage order is from top to bottom. The lifting mechanism 40 is also used in conjunction with the support mechanism 30 to transport the pallet 20 located at the bottom of the support frame 10 to the bottommost part of the support frame 10 for easy removal and use, wherein the order of removing the pallet 20 is from bottom to top.

[0030] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 8 As shown, the support frame 10 is U-shaped and has a first side wall 11 and a second side wall 12. The lower end of the tray 20 is provided with a roller 21. The tray 20 can enter or be taken out from the U-shaped opening side of the support frame 10. A guide plate 13 is provided at the bottom of the support frame 10. A guide groove 131 that cooperates with the roller 21 is provided on the guide plate 13, so that the tray 20 can be positioned and placed in the support frame 10 through the guide plate 13, so that the tray 20 can be lifted to the unloaded support mechanism 30 for storage under the action of the lifting mechanism 40.

[0031] It can be understood that a pulling and pushing mechanism can be arranged at the inner bottom end of the support frame 10, which is used to conveniently and efficiently pull the tray 20 into the support frame 10, so as to facilitate the lifting of the tray 20 to the empty supporting mechanism 30 under the action of the lifting mechanism 40 for storage, or under the action of the lifting mechanism 40, the pulling and pushing mechanism can conveniently and efficiently push the tray 20 out of the support frame 10, thereby facilitating the taking of the tray 20 by the staff, wherein the pulling and pushing mechanism can be a hydraulic telescopic rod.

[0032] It can be conceived that, in order to prevent the surface of the tray 20 from accumulating too much dust after the tray 20 is placed inside the support frame 10, a cover plate can be added to the top end of the support frame 10, and an opening allowing the tray 20 to enter and exit can be reserved at the bottom end of the plate.

[0033] In this embodiment, as shown in Figures 1-8 A plurality of through mounting holes 14 are symmetrically provided on the first side wall 11 and the second side wall 12 of the U-shaped support frame 10 in the vertical direction, and each through mounting hole 14 is correspondingly provided with a set of supporting mechanisms 30 through a matching shaft 141. The lower end of any tray 20 is supported by four supporting mechanisms 30 located on the same horizontal plane.

[0034] The supporting mechanism 30 comprises a supporting piece 31 rotatably mounted on the matching shaft 141 in the through mounting hole 14. The supporting piece 31 has a left branch 311, a middle branch 312, and a right branch 313. The middle branch 312 is in a vertical state, the left branch 311 is perpendicular to the lower end of the middle branch 312, and the right branch 313 forms an acute angle with the middle branch 312. The upper end of the middle branch 312 is connected to the top wall of the through mounting hole 14 by a traction spring 32, and the middle branch 312 is subjected to the resultant force of the traction spring 32 towards the inside of the support frame 10. A stop rod 33 is arranged on the side of the middle branch 312 towards the inside of the support frame 10 and fixed in the through mounting hole 14. The left branch 311 has a horizontal bearing part 3111 towards the inside of the support frame 10 for providing horizontal support for the tray 20. An arc-shaped easy-entry part 3112 is arranged below the horizontal bearing part 3111 on the left branch 311, which facilitates the upward lifting of the tray 20 under the action of the lifting mechanism 40. The upper end surface of the tray 20 first contacts the arc-shaped easy-entry part 3112 and causes the supporting piece 31 to rotate clockwise around the matching shaft 141 until the tray 20 is separated from the supporting piece 31. At this time, the traction spring 32 pulls the supporting piece 31 back to the horizontal state of the horizontal bearing part 3111 under the blocking of the stop rod 33. Then, the lifting mechanism 40 drives the tray 20 to move downward, and the tray 20 can stably sit on the horizontal bearing part 3111 of the supporting piece 31.

[0035] A rotating shaft 34 is provided at one end of the right branch 313. A mating rod 35 is rotatably connected to the rotating shaft 34. A torsion spring 36 is provided on the outer periphery of the section of the rotating shaft 34 located between the mating rod 35 and the right branch 313. The two ends of the torsion spring 36 are fixedly connected to the right branch 313 and the mating rod 35 respectively. A limiting plate 3131 located below the mating rod 35 is integrally provided at the end of the right branch 313 away from the middle branch 312.

[0036] In other embodiments, such as Figure 6 As shown, no traction spring 32 is installed on the middle branch 312; instead, the center of gravity of the support member 31 is concentrated on the left branch 311 at the end away from the support member 31 and the mating shaft 141 (e.g. Figure 6 As shown in G), when the pallet 20 is lifted upward under the action of the lifting mechanism 40, the upper surface of the pallet 20 first contacts the arc-shaped easy-entry part 3112 and causes the support member 31 to rotate clockwise around the mating shaft 141 until the pallet 20 is separated from the support member 31. At this time, under the gravity of the left branch 311, the left branch 311 will drive the support member 31 to rotate in the opposite direction around the mating shaft 141 and under the obstruction of the stop bar 33, the horizontal bearing part 3111 is in a horizontal state. Next, the lifting mechanism 40 drives the pallet 20 to move downward, and the pallet 20 can be stably placed on the horizontal bearing part 3111 of the support member 31.

[0037] In this embodiment, as Figures 1-8 As shown, the lifting mechanism 40 includes a drive motor 41 respectively disposed on the side of the first side wall 11 and the second side wall 12 facing away from the interior of the support frame 10 and located at the upper end of the first side wall 11 and the second side wall 12 respectively; a lead screw 42 is disposed at the output shaft end of the drive motor 41; a mating seat 43 is disposed at the lower end of the first side wall 11 and the second side wall 12 respectively; the end of the lead screw 42 away from the drive motor 41 is rotatably connected to the mating seat 43; a lifting rod 44 is disposed on the lead screw 42 and driven to lift and lower by the lead screw 42; a support rod 441 is disposed on the side of the lifting rod 44 facing the interior of the support frame 10 and extending into the interior of the support frame 10; and an extension part 442 is disposed at the lower end of the lifting rod 44 that can abut against the mating rod 35.

[0038] In order to make the pallet 20 more stable during the lifting mechanism 40, each lifting rod 44 is provided with two support rods 441 extending into the support frame 10 on one side facing the inside of the support frame 10. Correspondingly, the first side wall 11 and the second side wall 12 are respectively provided with sliding grooves 15 in the vertical direction to cooperate with the support rods 441.

[0039] When the tray 20 needs to be taken out from the supporting mechanism 30, the lifting mechanism 40 is first driven to make the supporting rod 441 lift the tray 20 upward by a distance and ensure that a certain gap is reserved between the tray 20 and the tray 20 above: in this process, the lifting rod 44 and the extension part 442 first contact the matching rod 35, the extension part 442 is in extrusion contact with the matching rod 35 as the lifting rod 44 rises, the matching rod 35 rotates clockwise around the rotating shaft 34 and abuts against the limiting plate 3131 under the action of the torsional spring 36, and when the extension part 442 moves upward and is out of contact with the matching rod 35;

[0040] Next, the lifting mechanism 40 is driven to make the supporting rod 441 move downward with the tray 20: in this process, the extension part 442 first contacts the matching rod 35, the matching rod 35 is subjected to the force of the overall downward movement, at this time, under the action of the limiting plate 3131, the matching rod 35 drives the supporting piece 31 to rotate clockwise around the matching shaft 141, until the left branch 311 of the supporting piece 31 rotates clockwise around the matching shaft 141 to penetrate the mounting hole 14, at this time, the tray 20 can be smoothly lowered from the support frame 10 and out of the interference of the left branch 311, the length of the extension part 442 can satisfy that the extension part 442 can be in contact with the matching rod 35 at all times during the lowering process, and then when the tray 20 is out of the interference of the left branch 311, the extension part 442 is out of contact with the matching rod 35, at this time, the supporting piece 31 is reset under the traction of the traction spring 32 and keeps the horizontal supporting part 3111 in a horizontal state;

[0041] Each time the tray 20 is taken out from the support frame 10, only the supporting mechanism 30 of the layer corresponding to the tray 20 needs to be subjected to process one and process two, and process one is ensured to be executed before process two, and after process two is executed, the tray 20 can be sequentially moved downward through each layer of the supporting mechanism 30 from top to bottom by driving the lifting mechanism 40 to drive the tray 20, so as to be smoothly moved to the lowest end of the support frame 10, and then the tray 20 can be taken out from the supporting mechanism 30.

[0042] Specific working principle: when the tray 20 needs to be placed in the support frame 10 for storage, the lifting mechanism 40 is first driven to move the supporting rod 441 downward to the lowest end of the support frame 10, then the tray 20 to be stored is placed on the supporting rod 441, and the lifting mechanism 40 is driven to move the supporting rod 441 upward to the horizontal supporting part 3111 of the uppermost empty supporting mechanism 30, and the order of storing the tray 20 is from top to bottom in the support frame 10;

[0043] When it is necessary to place the tray 20 in the support frame 10 for taking out, the tray rod 441 is driven to move by the lifting mechanism 40, and the supporting mechanism 30 of the layer corresponding to the tray 20 is processed once in process one and process two, and it is ensured that process one is performed before process two, then the tray 20 can be smoothly moved to the lowest end inside the support frame 10, and then the tray 20 is taken out from the supporting mechanism 30.
