Description

Technical Field

[0001] This utility model relates to a foldable turnover basket, specifically a foldable turnover basket for use in an intelligent warehousing system. Background Technology

[0002] In existing smart warehousing systems, one type involves arranging multiple shelves in a straight line, with gaps between adjacent shelves serving as vertical aisles for storing and retrieving boxes. A bottom conveyor line forms the bottom conveyor channel. An intelligent lifting mechanism is installed on this conveyor line, moving back and forth along the linearly arranged shelves to store and retrieve boxes. To enable the lifting mechanism to grip the boxes, lifting mechanisms are installed on the wide sidewalls of the boxes. The lifting mechanism is connected to a support mechanism that extends outwards and connects to it, or retracts to disengage, thus facilitating the loading and unloading of boxes. In this smart warehouse, the box's position is not detected by sensors but calculated by a computer. To calculate the box's position, multiple protrusions are installed on the conveyor belt, and multiple grooves are installed on the bottom of the box. The grooves and protrusions engage to position the box on the conveyor belt, and the computer calculates relevant data, such as the rotational speed of the servo motor driving the conveyor belt, to determine the box's position within the warehouse.

[0003] The specific structure of the aforementioned cargo box is detailed in the utility model patent application with announcement number CN211495522U. However, the aforementioned cargo box is a one-piece structure, which has the disadvantages of occupying a lot of space and being inconvenient for transportation. Therefore, the use of a foldable turnover box was considered. However, existing foldable turnover boxes lack positioning holes and lifting mechanisms adapted to the aforementioned warehousing system, and also suffer from insufficient strength, especially on the wide sides, making them prone to damage during storage and retrieval operations in the aforementioned warehousing system. Therefore, it is considered to design a foldable turnover box that is fully adapted to the aforementioned warehousing system, avoiding the problem of reduced operating efficiency and positioning accuracy of the warehousing system due to damage to the turnover box. Utility Model Content

[0004] To address the issues of insufficient strength and unsuitability for specific warehousing systems in existing folding turnover baskets, this invention provides a folding turnover basket for intelligent warehousing systems that solves the aforementioned problems.

[0005] A foldable turnover basket for an intelligent warehousing system includes a rectangular base plate, and two long side plates and two wide side plates hinged to the four sides of the base plate and interconnected with each other. On the bottom surface of the base plate, a set of positioning holes are symmetrically provided along its long and wide sides respectively. At least two lifting mechanisms are provided on the outer wall of the wide side plates.

[0006] In a preferred embodiment of the foldable turnover basket for intelligent warehousing system provided by this utility model, the positioning hole has a guide surface on the inner wall at the opening position.

[0007] In a preferred embodiment of the foldable turnover basket for an intelligent warehousing system provided by this utility model, the middle area of ​​the bottom plate bulges upwards towards the top. The top surface of the bottom plate is a closed plane, and a retaining edge is provided along its edge. The long side plate and the wide side plate are both hinged to the top of the retaining edge. The retaining edge on the wide side is higher than the retaining edge on the long side. The long side plate is folded onto the bottom plate, and the wide side plate is folded onto the long side plate.

[0008] In a preferred embodiment of the foldable turnover basket for intelligent warehousing system provided by this utility model, the side guard on the wide side and the wide side plate are movably connected by one or more connecting mechanisms including a rotating shaft.

[0009] In a preferred embodiment of the foldable turnover basket for an intelligent warehousing system provided by this utility model, two long side plates are respectively located between the two ends of two wide side plates. A pair of elastic pins are provided on the outer wall of each long side plate. When the long side plates and wide side plates are unfolded, the elastic pins are respectively connected to the inner sides of the two ends of the wide side plates. Each elastic pin includes a rod, a handle, and a spring. The rod is slidably connected to the long side plate, with one end extending beyond the long side plate and the other end provided with the handle. The remaining portion is connected to the long side plate by the spring. When the long side plates and wide side plates are unfolded, the end of the rod extending beyond the long side plate is connected to the wide side plate.

[0010] In a preferred embodiment of the foldable turnover basket for an intelligent warehousing system provided by this utility model, a boss is provided on the bottom surface of the base plate, forming a step between the two. The positioning hole is provided on the bottom surface of the boss. When the long side plate and the wide side plate are unfolded, the step can connect with the inner top of the long side plate and the wide side plate. When the long side plate and the wide side plate are folded, the step can connect with the inner top of the side guard. The outer edge of the bottom surface of the boss is chamfered, the inner edge of the long side plate and the wide side plate away from the base plate is chamfered, and the inner edge of the top of the side guard is chamfered.

[0011] Compared with existing technologies, the foldable turnover basket for intelligent warehousing systems provided by this utility model has the following beneficial effects: 1. The turnover basket provided by this utility model is a folding design with positioning holes and lifting mechanism. It is compatible with this storage system and has the advantages of small space occupation and convenient storage.

[0012] 2. The turnover basket provided by this utility model is equipped with a retaining edge and adopts a closed bottom plate structure integrated with the retaining edge to prevent liquid leakage at the bottom of the turnover basket and ensure that the goods are well preserved.

[0013] 3. The turnover basket provided by this utility model is provided with a boss, and the side guards, long side plates and wide side plates are all designed to be connected with the boss. Sloping guides are provided at all docking positions so that the turnover basket can be stacked smoothly in both folded and unfolded states.

[0014] 4. The turnover basket provided by this utility model uses a pivot shaft to connect the wide side plate and the bottom plate, and the bottom plate is reinforced, providing excellent structural strength between the wide side plate and the bottom plate. Since the wide side plate bears the force whether the turnover basket is lifted manually or by a hoist in the storage system, the above-mentioned reinforcement can significantly ensure the long-term stable use of the turnover basket.

[0015] 5. The turnover basket provided by this utility model adopts a folding mechanism in which the long side plate is folded down and the wide side plate is covered up. When the turnover basket is unfolded, the long side plate is sandwiched between the wide side plates. Since lifting the turnover basket from the wide side plates will naturally generate a pressure in the center, the design of the long side plate between the wide side plates can counteract this pressure, further improving the structural strength of the turnover basket and ensuring its long-term stable use.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please also refer to Figures 1 to 9 , Figures 1 to 3 These are structural diagrams of the foldable turnover basket for intelligent warehousing systems provided by this utility model when unfolded, when folded, and at the bottom. Figure 4 This is a structural diagram of the bottom plate of a foldable turnover basket used in intelligent warehousing systems. Figures 5 to 9 They are Figures 1 to 4 Enlarged view of the corner position of the intermediate elastic pin 4, the first buckle 121, the second buckle 133, the boss 14, and the location of the shaft hole 131.

[0020] The foldable turnover basket for intelligent warehousing system provided by this utility model includes a base plate 1, a long side plate 2, a wide side plate 3, and an elastic pin 4.

[0021] The base plate 1 is a rectangular plate with an elliptical section in the center that bulges upwards to enhance its structural strength. This prevents the bottom from bulging downwards after items are stacked, which could affect the normal operation of the storage system. The top surface of the base plate 1 is a closed plane without any perforations, and a retaining edge 11 is provided along its edge, forming a disc-shaped structure together with the base plate 1. Since the items inside the basket may be fresh food or other items that may sometimes bring water droplets or other liquids, the disc-shaped structure can prevent liquids from dripping and contaminating the next layer.

[0022] The height of the flange 11 on the wide side of the base plate 1 is greater than that on the long side. The top of the flange 11 on the wide side is hinged to the wide side plate 3, and the top of the flange on the long side is hinged to the long side plate 2.

[0023] Please also refer to Figures 13 to 14 These are enlarged and exploded views of the location of the first latch when unfolded, and enlarged and exploded views of the location of the first latch when folded. Figure 14 To show the first buckle 121, a small amount of the edge guard 11 has been removed.

[0024] Specifically, the inner side of the long side guard 11 has four notches in sequence, and a first buckle 121 is provided in the middle of the inner side of the notch. A first block 122 is provided at both ends of the inner side of the notch. There is a gap between the first buckle 121 and the first block 122.

[0025] The bottom of the long side plate 2 has four first buckles 21 at positions corresponding to the four first buckles 121. The first buckle 21 includes a first horizontal bar 211 parallel to the long side plate 2, and two vertical bars 212 vertically connected between the first horizontal bar 211 and the long side plate 2.

[0026] The hook side of the first buckle 121 faces outwards. Viewed from the perspective of a flat surface (see...). Figure 13 The first horizontal bar 211 has a step 213 located between the two vertical bars 212. The step 213 is used to hook with the first buckle 121 when folded. When laid flat, the first buckle 121 can be squeezed from top to bottom between the first buckle 121 and the guard 11 by utilizing its own elasticity, so that the first buckle 121 and the step 213 abut against each other vertically.

[0027] The two ends of the first horizontal bar 211, extending beyond the two vertical bars 212, are designated as end points 214. In the flat position, the thickness of the two end points 214 in the front-to-back direction is the same as that of the first horizontal bar 211, with the latter being longer. In the flat position, the two end points 214 abut against the two first stops 122. When rotated to the vertical position, the two end points 214 rotate accordingly, so that the extended positions of the end points 214 abut against the first stops 122 vertically.

[0028] When rotated to the vertical position, step 213 rotates accordingly, so that the first horizontal bar 211 and the first buckle 121 abut against each other vertically. During the rotation, the two vertical bars 212 swing in the gap between the first buckle 121 and the first stop 122.

[0029] Since the notch is located on the inside of the flange 11, the long side plate 2 can be rotated downwards to the horizontal direction, where it fits against the bottom plate 1; and it can be rotated upwards to the vertical direction, where the bottom of the long side plate 2 abuts against the outside of the flange 11.

[0030] Furthermore, five, six, or other numbers of notches can be provided on the long side edge 11, along with corresponding first buckles 121 and first stops 122. A consistent number of first buckles 21 are provided on the long side plate 2 for connection.

[0031] Please also refer to Figures 8 to 10 These are enlarged views of the shaft hole 131, and enlarged and exploded views of the second latch 133 when folded.

[0032] The flange 11 on the wide side has notches at both ends near the inner side, and a transverse shaft hole 131 is provided at the notch. The shaft hole 131 is inserted from the end of the flange 11, passes through the notch and continues to be inserted into the flange 11, forming a blind hole. The flange 11 on the wide side has an elongated notch at the middle near the inner side, and two second latches 133 are provided on the inner side of the notch.

[0033] The bottom of the wide side plate 3 has protruding bearing seats 32 at both ends, and the bearing seats 32 also have transverse through holes. Insert the bearing seats 32 into the notches at both ends of the retaining edge 11 on the wide side, and align the through holes of the bearing seats 32 with the shaft holes 131. Then, insert the rotating shaft 132 into the shaft holes 131 and the bearing seats 32 from the outside of the retaining edge 11 to achieve the shaft connection between the wide side plate 3 and the bottom plate 1.

[0034] The bottom of the wide side plate 3 has an elongated protrusion 33, which fills the elongated notch in the middle of the side guard 11. The protrusion 33 breaks off at the position corresponding to the two second buckles 133, and a second crossbar 34 is provided between the break points. The hook face of the second buckle 133 faces outward. Utilizing the elasticity of the second buckle 133 itself, the second crossbar 34 can be squeezed from top to bottom between the second buckle 133 and the side guard 11 to achieve a rotatable connection.

[0035] In the above structure, the bearing seat 32 is shaft-connected to the flange 1, and the second crossbar 34 is also rotatably connected to the second buckle 133. Since the notches of both are set on the inner side of the flange 11, the wide side plate 3 can be rotated downward to the horizontal direction, at which time it fits against the long side plate 2; it can be rotated upward to the vertical direction, at which time the bottom of the wide side plate 3 abuts against the outer side of the flange 11.

[0036] The two ends of the wide side panel 3 extend beyond the edges of the basket, allowing them to fit against the ends of the two long side panels 2 respectively. This design necessitates folding the long side panels 2 first before folding the wide side panel 3. The edges of the wide side panel 3 are rounded.

[0037] The outer wall of the wide side panel 3 has an arch-shaped recess on each side, which is the lifting mechanism 31. The top of the lifting mechanism 31 is an upward-convex arc shape, which allows the lifting mechanism in the storage system to extend and connect with the support mechanism, or retract the support mechanism to disengage, so as to realize the picking and placing of turnover baskets. Furthermore, a shallow groove 311 is provided along the centerline inside the lifting mechanism 31 to accommodate the screw head at the end of the support mechanism, so as to avoid damage to the basket body.

[0038] The outer wall of the wide side panel 3 has a grid-like reinforcing rib in the middle area. At the top, there are three horizontal closed grooves; the left and right sides below are closed recesses, and the middle position is a through hole used as a gripper; further below is a hollow structure of six vertical bars.

[0039] The outer wall of the long side plate 2 is provided with a grid-like reinforcing rib. The top position has a large number of horizontal closed grooves; below are six closed grooves for setting elastic pins 4; further below are multiple sets of vertical hollow structures, among which a square area in the middle of the bottom side is closed and used to set up mechanisms such as QR codes or RFID blocks for system identification.

[0040] Please see Figure 5 ,yes Figure 1 Enlarged view of the location of the flexible pin 4.

[0041] Two elastic pins 4 are symmetrically arranged in six closed grooves on the outer wall of the long side plate 2, including a pin 41, a positioning rod 42, a connecting rod 43, and a handle 44 connected in sequence. The handle 44 is located in the first groove near the middle. The connecting rod passes through the first partition to the second groove and connects to the spring 45 and the positioning rod 42. The spring 45 is an S-shaped structure symmetrically arranged on its upper and lower sides and extends to the adjacent side to abut against the first partition. The positioning rod 42 is enlarged in width and thickness and passes through the second partition to the third groove, abutting against the second partition. The end of the positioning rod 42 is connected to the pin 41, which is a T-shaped structure with its two sides protruding from the inner wall of the third groove to abut against it, and its end extending through to the outside of the long side plate 2.

[0042] Since the two ends of the wide side plate 3 can respectively fit into the ends of the two long side plates 2, the two ends of the wide side plate 3 are provided with insertion holes that can be connected to the pins 41. When the pins 41 are connected to the insertion holes, the long side plates 2 and the wide side plates 3 are fixed and maintained in the unfolded state.

[0043] In this structure, by pulling the handle 44 to the nearest side, the pin 41 can be retracted into the long side plate 2, unlocking the long side plate 2 from the wide side plate 3, and then folding can be performed. Conversely, by releasing the handle 44, the spring 45 pushes the pin 41 outward to the outside of the long side plate 2, where it engages with the end hole of the wide side plate 3.

[0044] Please see Figure 7 ,yes Figure 3 Enlarged view of the corner position of the central boss 14.

[0045] A smaller boss 14 is provided in the middle of the bottom surface of the base plate 1, forming a step between the base plate 1 and the boss 14. The step area between the base plate 1 and the boss 14, as well as the bottom surface of the boss 14, adopt a grid-like reinforcing rib structure.

[0046] On the other hand, the inner and outer sides of the flange 11 are aligned with the inner and outer sides of the long side plate 2 and the wide side plate 3 when unfolded. The outer side of the boss 14 and the inner side of the flange 11 are connected to the inner side of the long side plate 2 and the wide side plate 3 when unfolded.

[0047] Therefore, when the long side panel 2 and the wide side panel 3 are folded, the boss 14 can connect with the top of the guard 11; when the long side panel 2 and the wide side panel 3 are unfolded, the boss 14 can connect with the top of the long side panel 2 and the wide side panel 3. This facilitates the stacking of multiple turnover baskets.

[0048] A chamfer is provided on the outer edge of the bottom surface of the boss 14. At the highest point of the flange 11, that is, at both ends of the flange 11 on the wide side, a chamfer is provided on the inner edge of its top to facilitate vertical alignment when stacked in the folded state. In the unfolded state of the long side plate 2 and the wide side plate 3, a chamfer is provided on the inner edge of its top to facilitate vertical alignment when stacked in the unfolded state.

[0049] On the bottom surface of the boss 14, six positioning holes 15 are provided at equal intervals along the wide side, with the first and last two positioning holes 15 located at the two corners of the boss 14, respectively; and seven positioning holes 15 are provided at equal intervals along the long side, with the first and last ends leaving the corners of the boss 14 unoccupied. The spacing between the positioning holes 15 arranged along the wide side is the same as the spacing between the positioning holes 15 arranged along the long side.

[0050] The positioning hole 15 is a rectangular hole. The positioning holes 15 arranged along the wide side are parallel to the wide side of the base plate 1 in the length direction, and the positioning holes 15 arranged along the long side are parallel to the long side in the length direction. The inner wall of the positioning hole 15 is provided with an inward slope on all four sides.

[0051] Four-sided pyramidal protrusions are arranged on the conveyor belt at the same spacing as the positioning holes 15, which are used to connect with the positioning holes 15 to realize the positioning of the turnover basket on the conveyor belt.

[0052] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
