Description

Technical Field

[0001] This invention relates to the field of transport box technology, and specifically to a transport box for egg turnover. Background Technology

[0002] During the bulk transportation and turnover of poultry products such as eggs, special transport boxes or turnover boxes are usually required to protect the eggs from damage caused by squeezing, collision and bumping during handling and transportation.

[0003] During transportation, in order to minimize the risk of egg breakage due to lateral swaying of the egg tray inside the box, existing transport boxes generally adopt the method of reducing the gap between the egg tray and the inner wall of the box to achieve positioning constraint. That is, the outer perimeter of the egg tray is designed to be basically the same as the inner cavity of the box, and the gap between the two is often only a few millimeters.

[0004] While this design does provide good anti-shaking during transportation, it causes great inconvenience to operators during loading and unloading. Due to the small gap, it is difficult for operators to insert their fingers between the edge of the pallet and the side wall of the box. As a result, when picking up or placing egg pallets, special tools such as clamps can be used, or the box can be tilted to let the pallet slide out by gravity. This makes the operation difficult and inefficient. During the picking and placing process, the eggs are prone to rolling and breaking due to the tilt of the pallet. Moreover, the picking and placing can often only be done layer by layer, which further reduces the turnover efficiency and makes it impossible to achieve overall and rapid transfer. It is difficult to meet the requirements of modern logistics for high efficiency and low damage. Summary of the Invention

[0005] This invention provides a transport box for egg turnover, aiming to solve the problems of difficult and inefficient egg handling and placement in related technologies, and the inability to achieve overall and rapid transfer.

[0006] The egg turnover transport box of the present invention includes: Box; The base plate is detachably installed at the bottom of the box to support the egg tray; The locking element is movably mounted on the base plate and has a locked state and an unlocked state. The push component is connected to the locking component via a transmission mechanism; The driving component is used to drive the movement of the push component, so as to switch the locking component between the locked and unlocked states. When the locking mechanism is in the locked state, the housing and the base plate are relatively fixed; when the locking mechanism is in the unlocked state, the housing can be separated from the base plate.

[0007] Preferably, the bottom of the housing is provided with an insert plate, and the bottom plate has a slot adapted to the insert plate. The insert plate has a locking groove. The locking component includes a locking plate, which is inserted into the locking groove when locked and removed from the locking groove when unlocked.

[0008] Preferably, the bottom of the base plate is provided with a receiving box, and the locking member and the pushing assembly are installed in the receiving box; the side wall of the receiving box is provided with a through groove, and the locking plate is slidably assembled in the through groove.

[0009] Preferably, the locking component further includes a mounting plate, which is slidably mounted on the base plate, and the locking plate is fixed on the mounting plate; the pushing component is connected to the mounting plate to drive its sliding.

[0010] Preferably, the pushing component includes a frame, a connecting rod, a turntable, and a push rod. The turntable is rotatably mounted on the base plate, and the push rod is eccentrically mounted on the turntable and extends into the frame. The frame is connected to the locking component via the connecting rod. The driving component includes a lead screw, a sliding sleeve, and a lever. The lead screw is rotatably mounted on the base plate, the sliding sleeve is threaded onto the lead screw and slides with the base plate, and the lever is fixed on the sliding sleeve. A lever groove is provided on the turntable, and the lever extends into the lever groove.

[0011] Preferably, the top of the box is detachably covered with a cover plate, and the bottom of the cover plate is provided with a flexible pad and a pressure bar for pressing the uppermost egg tray and eggs together.

[0012] Preferably, the top of the cover plate has a groove, and the bottom of the base plate has a receiving box. The shape of the groove is adapted to the bottom contour of the receiving box, which is used for stacking and limiting multiple transport boxes.

[0013] Preferably, the box body is formed by two opposing long side plates and two opposing short side plates joined end to end. The adjacent long side plates and short side plates are rotatably connected by a vertical shaft, so that the box body can be folded. A limiting groove is opened in the vertical shaft, and a plug rod is provided in the limiting groove. When the plug rod is inserted, it restricts the relative rotation of the adjacent side plates, and when it is pulled out, it allows the relative rotation of the adjacent side plates.

[0014] Preferably, the end of the vertical shaft is provided with a threaded groove that communicates with the limiting groove, and the end of the insertion rod is provided with a threaded post that is rotatably connected to the threaded groove. Beneficial effects

[0015] 1. When in use, the invention achieves "integrated loading and unloading" through the separable design of the base plate and the box body. When loading, all pallets can be stacked on the base plate first, and then the box body can be fastened. When unloading, the box body can be lifted to expose the entire contents, which greatly shortens the loading and unloading time. It is suitable for use with automated handling equipment, enabling rapid and batch processing, improving efficiency several times over, and reducing accidental damage caused by manual layer-by-layer operation.

[0016] 2. When in use, the box adopts a foldable design. Through the cooperation of the insertion rod and the limiting groove, the box can switch between stable support and foldable storage. It can maintain stable support when transporting eggs. When the empty box is recycled or idle, it can be quickly folded into a flat shape. The space occupancy rate is much lower than that of a rigid box that cannot be folded, which significantly reduces storage and return transportation costs. Attached Figure Description

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 8As shown, the egg turnover transport box of the present invention includes a box body 10, a bottom plate 20, a locking member 30, a pushing component 40, a driving component 50, and a cover plate 60. The bottom plate 20 is detachably disposed below the box body 10 for supporting the egg tray. The locking member 30 is located on the bottom plate 20 and can be driven by the driving component 50 to operate the pushing component 40, switching between a first state and a second state. In the first state, the box body 10 and the bottom plate 20 are locked, and in the second state, they are unlocked. When the box body 10 and the bottom plate 20 are locked, the box body 10 and the bottom plate 20 remain fixed, enabling stable turnover and transportation of eggs. When the box body 10 and the bottom plate 20 are unlocked, the box body 10 and the bottom plate 20 can be separated, allowing for the overall loading and unloading of eggs. The cover plate 60 is disposed on the top of the box body 10 for closing the box body 10 and limiting the position of the uppermost egg tray and eggs.

[0028] refer to Figure 2 , Figure 2 as well as Figure 6 The box body 10 is rectangular in shape and is formed by two opposing long side plates 11 and two opposing short side plates 12 joined end to end. The long side plates 11 have a pick-and-place slot 111 to allow the user's hands to enter and then pick up and place the egg tray layer by layer. The short side plates 12 have a gripping slot 121 to allow the user's hands to grip and carry the box body 10. Both the long side plates 11 and the short side plates 12 are equipped with anti-collision air cushions (not shown in the figure), which can reduce the range of movement of the egg tray and cushion the shaking of the egg tray.

[0029] refer to Figure 2 , Figure 3 as well as Figure 4 The bottom of the base plate 20 is provided with a receiving box 21 for installing the locking component 30 and the pushing component 40. The interior of the base plate 20 has multiple through slots 22, which are distributed in a rectangular array around the periphery of the receiving box 21. The bottom sides of the long side plate 11 and the short side plate 12 are fixedly installed with insert plates 13 that are compatible with the slots 22. The insert plates 13 on the long side plate 11 and the short side plate 12 are respectively inserted into the corresponding slots 22. The bottom end of the insert plate 13 extends through and to the side of the receiving box 21. The insert plate 13 has a locking groove 131. The side wall of the receiving box 21 has a through groove 211 corresponding to the locking groove 131.

[0030] refer to Figure 4 and Figure 5The locking component 30 includes a mounting plate 31 and a locking plate 32. The mounting plate 31 is located inside the receiving box 21 and is slidably mounted on the bottom of the base plate 20 with a single degree of freedom. The locking plate 32 is fixedly mounted on the mounting plate 31, with its end away from the mounting plate 31 slidably mounted in the through groove 211. The locking plate 32 can switch to a first state of extending out of the through groove 211 and a second state of being retracted into the through groove 211 as the mounting plate 31 moves. When the locking plate 32 is switched to the first state, it can be inserted into the locking groove 131 on the insert plate 13, thereby locking the insert plate 13. The locking plate 13 is locked in place so that it cannot disengage from the slot 22, thereby securing the box 10 and the base plate 20 to ensure stable transport during egg turnover. When the locking plate 32 switches to the second state, it can be pulled out from the locking groove 131 on the plate 13 to unlock the plate 13, allowing it to be pulled out from the slot 22. This separates the box 10 from the base plate 20, allowing the box 10 to be pulled out from the base plate 20 and above the egg trays, so that all the egg trays stacked on the base plate 20 are fully exposed, facilitating the overall multi-layer handling and transfer of the stacked eggs.

[0031] Specifically, there are multiple mounting plates 31, which are divided into horizontal plates and vertical plates. The horizontal plates are located on the side of the insert plate 13 on the long side plate 11 and can slide freely along the width direction of the base plate 20. The locking plate 32 above them corresponds to the locking and fixing of the insert plate 13 on the long side plate 11. The vertical plates are located on the side of the short side plate 12 and can slide freely along the length direction of the base plate 20. The locking plate 32 above them corresponds to the locking and fixing of the insert plate 13 on the short side plate 12.

[0032] refer to Figure 4 and Figure 5 The pushing component 40 includes a frame 41, a connecting rod 42, a turntable 43, and a push rod 44. The frame 41 is located inside the receiving box 21 and is fixed to the mounting plate 31 by the connecting rod 42. The turntable 43 is rotatably mounted on the bottom of the base plate 20 inside the receiving box 21. The push rod 44 is vertically eccentrically mounted on the turntable 43, and the top end of the push rod 44 extends into the inside of the frame 41. By rotating the turntable 43 inside the receiving box 21, the push rod 44 rotates and moves inside the frame 41, which can push the frame 41 to slide along with the mounting plate 31, thereby switching the state of the locking plate 32 to lock or unlock the insert plate 13.

[0033] refer to Figure 4 and Figure 5The drive assembly 50 includes a lead screw 51, a sliding sleeve 52, and a lever 53. The lead screw 51 is rotatably mounted inside the housing 21. The sliding sleeve 52 is slidably mounted on the top of the base plate 20 and threadedly connected to the outside of the lead screw 51. The lever 53 is fixed to the bottom of the sliding sleeve 52. A groove 431 is provided on the upper side of the turntable 43 along its radial direction. The bottom end of the lever 53 extends into the inside of the groove 431. By rotating the lead screw 51, the sliding sleeve 52 is pushed to slide, so that the lever 53 moves and pushes the turntable 43 to rotate through the groove 431, thereby adjusting the state of the locking plate 32. A knob located outside the housing 21 is fixedly installed at the end of the lead screw 51 so that the user can rotate the lead screw 51 from the outside.

[0034] refer to Figure 1 and Figure 8 The bottom of the cover plate 60 is provided with a flexible pad 61 extending into the box body 10 and a pressure rod 62. After the cover plate 60 is closed, the flexible pad 61 can press the eggs on the top egg tray firmly, and the pressure rod 62 can press the top egg tray firmly, so as to prevent the egg tray and the top egg from being damaged by bouncing up and down during transportation. The top of the cover plate 60 is provided with a groove 63 that matches the container box 21, so as to limit the stacking of multiple transport boxes and prevent the stacked transport boxes from sliding at will. A latch (not shown in the figure) is provided between the cover plate 60 and the box body 10 to fix the cover plate 60 and the box body 10.

[0035] refer to Figure 6 and Figure 7 Vertical shafts 70 are fixedly installed at the ends of both the long side plate 11 and the short side plate 12. The vertical shafts 70 on adjacent long side plates 11 and short side plates 12 are coaxially rotatably assembled, allowing the long side plates 11 and short side plates 12 to rotate relative to each other, thereby folding the box 10 to save space and facilitate storage. A polygonal limiting groove 71 is provided inside the vertical shaft 70 along its axial direction. A polygonal insert rod 72 is inserted into the limiting groove 71, and the two ends of the insert rod 72 extend into the two coaxially rotatably assembled vertical shafts 70, thereby restricting the mutual rotation between the long side plate 11 and the short side plate 12 and keeping the box 10 in a rectangular state for easy handling of eggs.

[0036] The top of the vertical shaft 70 near the cover plate 60 is coaxially provided with a threaded groove 73 that communicates with the limiting groove 71. The top of the insertion rod 72 is rotatably fitted with a threaded post 74 that is threaded into the threaded groove 73. By screwing the threaded post 74 into the threaded groove 73, the insertion rod 72 is secured in the limiting groove 71, restricting the rotation between the two vertical shafts 70, thereby keeping the box 10 in a rectangular open state for easy turnover of eggs. By screwing the threaded post 74 out of the threaded groove 73, the insertion rod 72 can be pulled out of the limiting groove 71, thereby releasing the restriction between the vertical shafts 70, allowing the upper and lower vertical shafts 70 to rotate, and thus allowing the box 10 to be folded for easy storage.

[0037] Working principle: When filling eggs, the egg trays are neatly stacked on top of the base plate 20. Then, the entire box 10 is placed over the egg trays from top to bottom, so that the insert plate 13 at the bottom of the box 10 is inserted into the slot 22 of the base plate 20. At this time, the lead screw 51 in the drive assembly 50 is in the initial position. The user turns the knob at the end of the lead screw 51, and the lead screw 51 rotates, driving the sliding sleeve 52 to move linearly. The sliding sleeve 52 drives the lever 53 to move, and the lever 53 moves within the slot 431 of the turntable 43. The movement of the turntable 43 causes it to rotate. As the turntable 43 rotates, the eccentric push rod 44 on it pushes the frame 41 to move. The frame 41, through the connecting rod 42, causes all the mounting plates 31 to slide away from the insert plate 13. The locking plate 32 on the mounting plate 31 then extends out from the through slot 211 of the receiving box 21, switches to the first state, and is precisely inserted into the locking slot 131 of the insert plate 13. The insert plate 13 is firmly locked in the slot 22, and the box 10 and the bottom plate 20 are fixed as a whole. Then the cover plate 60 is put on, and the top layer of eggs and the tray are pressed together by the flexible pad 61 and the pressure rod 62, thus completing the filling of eggs.

[0038] When the eggs are removed, the knob of the screw 51 is turned in the opposite direction, driving all the components of the drive assembly 50 to move in the opposite direction. The lever 53 pushes the turntable 43 to rotate in the opposite direction, and the push rod 44 pulls the frame 41, the connecting rod 42 and all the mounting plates 31 to slide towards the insert plate 13. The locking plate 32 is then pulled out from the locking groove 131 and completely retracted into the through groove 211, switching to the second state. The lock of the insert plate 13 is released. At this time, the operator can grab the gripping groove 121 on the short side plate 12 and lift the entire box 10 upward, so that the insert plate 13 is completely disengaged from the slot 22 of the bottom plate 20. After the box 10 is removed, all the egg trays stacked on the bottom plate 20 are fully exposed. The user can easily pick up and put down the whole or transfer multiple layers without having to pick them up layer by layer.

[0039] When the transport box is not in use, unscrew the threaded post 74 located at the top of the vertical shaft 70 to disengage it from the threaded groove 73, and then pull out the polygonal insert 72 from the limiting grooves 71 of the upper and lower vertical shafts 70 to release the rotation restriction on the adjacent vertical shafts 70. The long side plate 11 and the short side plate 12 can rotate around the vertical shaft 70, so that the rectangular box body 10 is flattened and folded, greatly reducing the volume and making it easy to store.

[0040] This invention achieves "integrated loading and unloading" through the separable design of the base plate 20 and the box body 10. During loading, all pallets can be stacked on the base plate 20 first, and then the box body 10 can be fastened. During unloading, the box body 10 can be lifted to expose the entire box, greatly shortening loading and unloading time. It is suitable for use with automated handling equipment (such as forklifts, AGVs, etc.), enabling rapid, batch processing and increasing efficiency several times over, while reducing accidental damage caused by manual layer-by-layer handling. The box body 10 adopts a foldable design; through the cooperation of the insertion rod 72 and the limiting groove 71, the box body 10 can switch between stable support and folded storage, maintaining stable support during egg transportation. When the box is recycled or idle, it can be quickly folded into a flat shape, with a space occupancy rate far lower than that of a rigid box that cannot be folded, significantly reducing storage and return costs; the cooperation between the insert plate 13 and the slot 22 achieves positioning, while the locking component 30 provides a reliable mechanical lock to ensure that the box body 10 and the bottom plate 20 will not accidentally separate during transportation; the anti-collision air cushion can absorb lateral impact and shaking energy, and the flexible pad 61 and pressure bar 62 of the cover plate 60 press the eggs and the tray respectively, effectively solving the problem of "egg jumping" during transportation, and the groove 63 on the top of the cover plate 60 matches the contour of the bottom container box 21, so that multiple full transport boxes can be stacked stably and are not easy to slip off.

[0041] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
