Description

Technical Field

[0001] This utility model belongs to the field of warehousing technology, and in particular relates to a cargo storage device and a cargo status detection system. Background Technology

[0002] To fully utilize warehouse space and facilitate logistics terminal management, related technologies employ bins to hold goods and stack them, forming a bin stack. The stacks do not require support frames; adjacent bins are in direct contact. However, due to misalignment during bin placement by the handling device, adjacent bins on different layers are prone to drifting and difficult to reliably align. During stacking, the positional deviation gradually accumulates in the upper bins as the stack height increases, resulting in poor stability and a tendency to tip over. Utility Model Content

[0003] In view of this, the present invention provides a cargo storage device and a cargo status detection system to solve the technical problem of how to reduce the risk of tipping over of the material bin assembly.

[0004] To solve the above problems, the technical solution provided by this utility model embodiment is as follows:

[0005] This utility model embodiment provides a cargo storage device, including: a material box for storing cargo, wherein at least two layers of the material box are stacked vertically; a status detection component installed on the edge of the upper surface and / or lower surface of the material box to detect the stacking status; the stacking status includes: a first state in which two adjacent material boxes are aligned and a second state in which two adjacent material boxes are misaligned; wherein, in the first state, the status detection component is pressed against by the adjacent material box; and in the second state, the status detection component is in a free state.

[0006] In some embodiments, the state detection element is deformable, and the edge is provided with a mounting groove for receiving the state detection element; in the first state, the state detection element is pressed against the mounting groove; in the second state, at least a portion of the state detection element protrudes from the edge in the vertical direction.

[0007] In some embodiments, the mounting groove has a first opening at the edge and a second opening on the outer wall of the hopper; in the first state, at least a portion of the status detection element is exposed to a sensing area in the second opening for sensing by a sensing device.

[0008] In some embodiments, the state detection element includes: a deformable part, one end of which abuts against the bottom wall of the mounting groove away from the first opening in a vertical direction; and an abutting part connected to the other end of the deformable part in a vertical direction, wherein, when the state detection element is in a free state, the abutting part extends to protrude from the first opening; wherein the deformable part is at least partially deformable to extend and retract with the movement of the abutting part, and the deformable part includes a sensing part adjacent to the second opening, the sensing part entering and leaving the sensing area as the deformable part extends and retracts.

[0009] In some embodiments, the deformable body is further provided with an elastic portion connected to the sensing portion on the side near the second opening, and in the second state, the distance from the elastic portion to the sensing area is greater than a preset distance; and / or, at least a portion of the deformable body on the side opposite to the second opening bends toward the direction of the second opening.

[0010] In some embodiments, the mounting groove is disposed adjacent to the upper surface of the hopper, the first opening is located at the edge of the upper surface of the hopper, and both the first opening and the second opening are spaced at a predetermined distance from the outer edge of the upper surface.

[0011] In some embodiments, the hopper includes: a body having a receiving cavity and an upper opening communicating with the receiving cavity at its upper end; and a base disposed at the lower end of the body; wherein, in a top view of the hopper, the outer edge of the base is spaced apart from the outer edge of the upper opening by a preset value.

[0012] In some embodiments, the lower edge of the body protrudes horizontally from the outer edge of the base to abut against the upper surface of another of the hoppers; the mounting groove is adjacent to the lower surface of the body, and the first opening is located at the edge of the lower surface of the body.

[0013] This utility model embodiment also provides a cargo status detection system, including the cargo storage device described above; the cargo status detection system further includes a sensing device for detecting the position of the status detection component.

[0014] In some embodiments, the number of sensing devices is the same as the number of status detection elements; wherein each sensing device generates stacking status information based on the positions of all status detection elements at the stacking positions of two adjacent bins.

[0015] This utility model provides a cargo storage device, including a bin and a status detection component. The status detection component is installed on the edge of the upper and / or lower surface of the bin and is used to detect the stacking state of two adjacent bins. The stacking state includes a first state where the two adjacent bins are aligned and a second state where they are misaligned. In the first state, the status detection component is pressed against by the adjacent bin; in the second state, the status detection component is in a free state. Another bin adjacent to the bin where the status detection component is installed can press against the status detection component when aligned, causing the status detection component to switch from a free state to a pressed state. Therefore, the alignment of two adjacent stacked bins can be visually determined based on the status of the status detection component, allowing for a timely interruption of the positional deviation caused by the misalignment of the two adjacent bins, reducing the possibility of this positional deviation accumulating upwards to the upper bins in the bin group. Therefore, by setting a movable state detection component, this utility model embodiment makes it feasible to align each pair of adjacent layers of bins in a stack of bins, thereby improving the stability of the stacked bins, reducing the possibility of the bins tipping over, and making the bins more reliable.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0028] In the following description, the terms "first," "second," "etc." are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the directions under normal use, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use.

[0029] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0030] like Figure 1As shown, this embodiment of the utility model provides a cargo storage device 10, which includes a material bin 1 and a status detection component 2. The interior of the material bin 1 is used to store goods. It should be noted that the material bin 1 is not limited in shape, size, or other parameters. All material bins 1 required for warehousing can be one or more standard parts. Specifically, the material bin 1 may have a detachable cover, or it may not have a cover and only form a receiving cavity 141 with an upper opening 142 (see...). Figure 6 As long as the material box 1 can hold the goods, it is acceptable. The material boxes 1 are stacked at least two layers high. Specifically, the material box group formed by stacking the material boxes 1 includes at least two material boxes 1. The material box group can also have three, four, five, etc.

[0031] There are various possible stacking positions for the bins, and this embodiment of the utility model does not limit them. For example, the stacked bin group can be placed on a warehouse shelf or directly on the warehouse floor, and the stacking action of bin 1 can be completed in the warehouse; the stacked bin group can be placed in the basket of a handling robot, and the forks of the handling robot can complete the stacking action of bin 1 in the basket. After bin 1 is stacked into a bin group, it is then placed in the warehouse; the stacked bin group can also be placed in the forks of a handling robot, and the telescopic arm of the handling robot can complete the stacking action of bin 1 in the forks. After bin 1 is stacked into a bin group, it is then placed in the warehouse; the stacked bin group can also be placed in the hopper of the transfer station, and the palletizing device of the transfer station can complete the stacking action of bin 1 in the hopper. After bin 1 is stacked into a bin group, it is then transported to the warehouse by a handling robot.

[0032] like Figure 1 As shown, the status detection element 2 is installed on the bin 1 and is used to detect the stacking status of the bins 1. In the bin group, each bin 1 may be equipped with the status detection element 2, or only some bins 1 may be equipped with the status detection element 2. For example, the upper and lower ends of the bins 1 in the odd-numbered layers of the bin group may be provided with the status detection element 2, while the bins 1 in the even-numbered layers may not be provided with the status detection element 2.

[0033] Specifically, the status detection element 2 is installed on the edge 11 of the upper surface of the material box, or the status detection element 2 is installed on the edge 11 of the lower surface of the material box. Of course, the status detection element 2 can be installed on both the edge 11 of the upper surface and the edge 11 of the lower surface of the material box. It should be noted that, as Figure 2As shown, the upper surface of the material bin 1 is the surface that forms all visible outer contours in the upper direction of the material bin 1. The upper surface of the material bin 1 can be a plane as shown in the schematic diagram of this application, or it can be a stepped surface. Similarly, the lower surface of the material bin 1 is the surface that forms all visible outer contours in the lower direction of the material bin 1. The lower surface of the material bin 1 can be a stepped surface as shown in the schematic diagram of this application, or it can be a plane. That is, both the upper and lower surfaces of the material bin 1 can be composed of two planes that are spaced apart from each other and connected in the vertical direction. It should be noted that, as Figure 2 and Figure 3 As shown, the material box 1 forms a receiving cavity 141, so the material box 1 has a certain wall thickness. The material box 1 has an inner sidewall that forms the receiving cavity 141 and an outer sidewall that forms the outer contour. Therefore, the edge 11 of the material box 1 can be simply understood as the part located between the inner sidewall and the outer sidewall in the upper and lower surfaces.

[0034] like Figure 1 As shown, the stacking states of the material bins 1 include a first state where two adjacent layers of material bins 1 are aligned and a second state where two adjacent layers of material bins 1 are offset. Both the first and second states are states that occur during the stacking process. It should be noted that the alignment and offset of the material bins 1 refer to each material bin 1 located in the same stack of material bins. The material bins in the same stack can be of the same or different specifications, but at least in the top view, the size and shape of each material bin 1 in the same stack are identical. The material bins in the same stack are stacked vertically. In the top view of the material bins in the same stack, the outermost edges of the upper and lower layers of material bins 1 basically overlap, indicating that the two adjacent stacked material bins 1 are aligned. It can be understood that, due to the allowable small error, "basic overlap" includes the case where all parts of the outermost edges completely overlap, and also the case where some edges do not completely overlap but the interval is small and will not affect the tilting of the material bin group. Conversely, in a top view of a stack of material boxes, if the outermost edges of the upper and lower layers of material boxes 1 intersect or are parallel (i.e. do not overlap), it indicates that the two adjacent stacked material boxes 1 are deviated.

[0035] like Figure 4 and Figure 5 As shown, in the first state, the state detection element 2 is pressed against the adjacent material box 1; in the second state, the state detection element 2 is in a free state. It should be noted that the state detection element 2 being pressed against indicates that it is under external pressure, while the free state of the state detection element 2 indicates that no external force is applied to it. That is, the other material box adjacent to the one on which the state detection element 2 is installed cannot press against the state detection element 2, which indicates that the two adjacent stacked material boxes 1 are misaligned. Figure 4 The diagram shows the state detection component 2 being pressed against the adjacent material box 1. At this time, the two adjacent stacked material boxes 1 are in the first aligned state. Figure 5The diagram shows the state detection component 2 in a free state. At this time, the two adjacent stacked bins 1 are in a deviated second state.

[0036] For ease of explanation, the following explanation will use a two-layer stack of two material boxes as an example, defining the upper material box as 1a and the lower material box as 1b. Figure 1 As shown, the state detection element 2 can be installed on the edge 11 of the upper surface. During the process of stacking the upper material box 1a onto the lower material box 1b, the upper material box 1a presses down against the state detection element 2. Alternatively, the state detection element 2 can be installed in the edge 11 of the lower surface. During the process of stacking the upper material box 1a onto the lower material box 1b, the lower material box 1b presses up against the state detection element 2. In general, the state detection element 2 can be pressed down during the switching between the first state and the second state. The alignment of two adjacent material boxes 1 can be determined based on whether the state detection element 2 is pressed down. For example, a sensor can be set up. When at least part of the state detection element 2 is pressed down and moves to a position that can be sensed by the sensor, it means that the two adjacent stacked material boxes 1 are in the first state, that is, the two adjacent stacked material boxes are aligned. Conversely, if the state detection element 2 remains in a free state and is not pressed down to a position that can be sensed by the sensor, it means that the two adjacent stacked material boxes 1 are in the second state, that is, the two adjacent stacked material boxes are misaligned. In other words, during the stacking process, the two adjacent stacked bins are not considered aligned until the status detection element 2 is pressed down so that at least a portion of the status detection element 2 moves to the correct position (e.g., a position that can be sensed by the sensing device 20).

[0037] This utility model provides a cargo storage device 10, including a storage bin 1 and a status detection element 2. The storage bin 1 is used to store cargo, and at least two layers of storage bins 1 are stacked vertically. The status detection element 2 is installed on the edge 11 of the upper and / or lower surface of the storage bin 1 and is used to detect the stacking status of two adjacent storage bins 1. The stacking status includes a first state in which two adjacent storage bins 1 are aligned and a second state in which two adjacent storage bins 1 are misaligned. In the first state, the status detection element 2 is pressed against by the adjacent storage bins 1; in the second state, the status detection element 2 is in a free state. Another bin adjacent to the bin installed with the status detection component 2 can press against the status detection component 2 when aligned, causing the status detection component 2 to switch from a free state to a pressed state. Then, the stacking state of the two adjacent stacked bins 1 can be intuitively judged based on the state of the status detection component 2. Thus, it can be determined whether the two adjacent bins 1 need to be adjusted in position based on whether the two adjacent bins 1 are aligned. This can interrupt the positional deviation caused by the deviation of the two adjacent stacked bins 1 in a timely manner, reducing the possibility of the positional deviation accumulating upward to the upper bin 1a of the bin group. This makes it easier for each pair of adjacent bins 1 in a stack of bins to be aligned, improving the stability of the stacked bin group and reducing the possibility of the bin group tipping over. In addition, since the status detection component 2 is installed on the material box 1 and its position information is consistent with that of the material box 1, during the stacking process, another material box 1 adjacent to the material box 1 on which the status detection component 2 is installed directly contacts the status detection component 2. Through the status detection component 2, it is possible to more accurately and intuitively determine whether the two adjacent material boxes 1 are aligned, with higher accuracy, making the material box group formed by stacking multiple material boxes 1 more reliable.

[0038] In some embodiments, such as Figure 4 and Figure 5 As shown, the state detection element 2 is deformable, meaning it can undergo deformation and recover from deformation. For example, the state detection element 2 can be an elastic element. Figure 4 The diagram shown illustrates the deformation of the condition detection component 2. Figure 5 The diagram shows the state detection element 2 in a free state after recovering its deformation. Edge 11 has a mounting groove 12 for accommodating the state detection element 2. The mounting groove 12 can be located at either the upper or lower edge 11. In a first state, the state detection element 2 is pressed against the mounting groove 12; in a second state, at least a portion of the state detection element 2 protrudes from the edge 11 in the vertical direction. That is, in its free state without being pressed, at least a portion of the state detection element 2 protrudes from the edge 11 in the vertical direction to facilitate contact with adjacent material boxes 1 during stacking. The state detection element 2 deforms under pressure in the first state to store elastic potential energy (see reference). Figure 4After the external force on the state detection element 2 disappears, the elastic potential energy stored in the state detection element 2 drives the state detection element 2 to automatically reset (refer to...). Figure 5 With this configuration, the state detection element 2 can automatically reset from the state of being pressed against the mounting groove 12 to the free state, and restore its posture of at least partially protruding from the edge 11 in the vertical direction. There is no need to manually reset the state detection element 2, making the operation simple. Furthermore, there is no need to install other components to drive the state detection element 2 to reset, resulting in a simple structure that is easy to implement.

[0039] In some embodiments, such as Figure 6 and Figure 7 As shown, the mounting groove 12 has a first opening 121 located at the edge 11 and a second opening 122 located on the outer wall of the hopper 1. The first opening 121 can be located at either the edge 11 of the upper surface or the edge 11 of the lower surface, so that when the state detection element 2 is in a free state, a portion of it can protrude beyond the edge 11 via the first opening 121 in the vertical direction. In the first state, at least a portion of the state detection element 2 is exposed to the sensing area 1221 in the second opening 122 for sensing by the sensing device 20 (see reference). Figure 4 Specifically, the entire area of ​​the second opening 122 can be called the sensing area 1221, or only a portion of the second opening 122 can be called the sensing area 1221. It can be understood that the area of ​​the sensing area 1221 is related to the type of sensing device 20. For example, if the sensing device 20 is configured as a photoelectric sensor, then the area of ​​the sensing area 1221 must be at least large enough for the light beam of the photoelectric sensor to pass through. However, in general, in the first state, referring to... Figure 4 Each sensing device 20 can sense at least a portion of the state detection element 2 through the second opening 122, thereby triggering the generation of information indicating that the two adjacent stacked material boxes 1 are in a first state. That is, when the sensing device 20 can sense at least a portion of the state detection element 2 through the second opening 122, it indicates that the two adjacent stacked material boxes 1 are aligned. In this way, the user can determine whether the two adjacent stacked material boxes 1 are aligned based on the information generated by the sensing device 20. This method is more automated and intelligent, and can convey the stacking status information of the two adjacent stacked material boxes 1 more accurately and efficiently than manual judgment.

[0040] In some embodiments, such as Figure 4 , Figure 5 and Figure 7As shown, the state detection element 2 includes a deformable part 21 and an abutting part 22. One end of the deformable part 21 in the vertical direction abuts against the bottom wall of the mounting groove 12 away from the first opening 121. It can be understood that the bottom wall of the mounting groove 12 represents the end wall of the mounting groove 12 away from the first opening 121. The abutting part 22 is connected to the other end of the deformable part 21 in the vertical direction. When the state detection element 2 is in a free state, the abutting part 22 extends to a position protruding from the first opening 121. Specifically, when the state detection element 2 is installed on the edge 11 of the upper surface, the mounting groove 12 is adjacent to the upper surface, and the first opening 121 is located on the edge 11 of the upper surface. In this case, the lower end of the deformable part 21 abuts against the bottom wall of the mounting groove 12, and the abutting part 22 is connected to the upper end of the deformable part 21, protruding from the edge 11 of the upper surface through the first opening 121 in a free state. Similarly, when the state detection element 2 is installed on the edge 11 of the lower surface, the mounting groove 12 is adjacent to the lower surface, and the first opening 121 is located on the edge 11 of the lower surface. In this case, the upper end of the deformable part 21 abuts against the bottom wall of the mounting groove 12, and the abutting part 22 is connected to the lower end of the deformable part 21, protruding from the edge 11 of the lower surface through the first opening 121 in a free state. It should be noted that this embodiment of the invention only roughly divides the state detection element 2 into two parts according to different positions and functions; it does not involve the division of the state detection element 2 into components. That is, the deformable part 21 and the abutting part 22 can be integrally formed.

[0041] At least a portion of the deformable part 21 is deformable to extend and retract with the movement of the abutment part 22. The deformable part 21 includes a sensing part 211 adjacent to the second opening 122, which enters and exits the sensing area 1221 as the deformable part 21 extends and retracts. Figure 4 The diagram shown is a schematic of the sensing unit 211 entering the sensing region 1221 as the deformation shape 21 is compressed. Figure 5 The diagram shows the sensing part 211 extending into the sensing area 1221 as the deformable part 21 extends. During the process of stacking the upper hopper 1a onto the lower hopper 1b, if the sensing part 211 enters the sensing area 1221, the sensing device 20 senses the sensing part 211 through the sensing area 1221 of the second opening 122, thereby generating information that the two adjacent stacked hoppers 1 are aligned in a first state. If the sensing part 211 does not enter the sensing area 1221, the sensing device 20 cannot sense the sensing part 211 through the sensing area 1221 of the second opening 122, thereby generating information that the two adjacent stacked hoppers 1 are misaligned in a second state. In the case of two adjacent stacked and aligned hoppers 1, if the upper hopper 1a is moved away from the lower hopper 1b, the compressed deformable part 21 releases its elastic force and extends, causing the sensing part 211 to leave the sensing area 1221 and return to the position of the protruding edge 11.

[0042] Thus, the contact part 22 receives pressure, at least part of the deformable part 21 can deform to store elastic potential energy in the first state and release elastic potential energy in the second state, and the sensing part 211 can change position with the extension and contraction of the deformable part 21. The sensing device 20 can generate information on the stacking state of two adjacent stacked boxes 1 by the position change of the sensing part 211. The structure is simple and easy to implement.

[0043] In some embodiments, such as Figure 4 , Figure 5 and Figure 7 As shown, the deformable part 21 near the second opening 122 is also provided with an elastic part 212 connected to the sensing part 211. In the second state, the distance from the elastic part 212 to the sensing area 1221 is greater than a preset distance. It can be understood that the elastic part 212 is elastic and can deform. The preset distance is greater than 0. The distance from the elastic part 212 to the sensing area 1221 is the distance from the elastic part 212 to the location of the second opening 122, and also the distance from the elastic part 212 to the outer wall of the material box 1. Specifically, the elastic part 212 can extend in a straight line or extend in a curved manner. When the elastic part 212 extends in a straight line, the distance from the elastic part 212 to the outer wall of the material box 1 represents the minimum straight-line distance from the elastic part 212 to the outer wall of the material box 1. When the elastic part 212 extends in a curved manner, the distance from the elastic part 212 to the outer wall of the material box 1 is the minimum distance from the midpoint of each arc of the curve to the outer wall of the material box 1. For example, in the schematic diagram shown in this application, referring to... Figure 7 The elastic part 212 bends and deforms, forming only an arc. Therefore, the distance between the elastic part 212 and the outer wall of the material box 1 is the distance H from the midpoint of this arc to the outer wall of the material box 1. In other words, the elastic part 212 extends in a direction away from the second opening 122 while bending. A preset distance is defined as H0. In some possible implementations, 2mm ≤ H0 ≤ 8mm, therefore, 2mm < H < 8mm. This arrangement ensures that only the sensing part 211 enters and exits within the sensing area 1221 that the sensing device 20 can sense. The elastic part 212 remains outside the sensing area 1221 without interfering with the information generation of the sensing device 20. It is also elastic enough to deform, allowing the sensing part 211 to switch positions, moving it to or away from the sensing area 1221.

[0044] In some embodiments, such as Figure 4 , Figure 5 and Figure 7As shown, at least a portion of the deformable part 21 on the side opposite to the second opening 122 bends toward the direction closer to the second opening 122. This bending can occur where only a portion of the deformable part 21 on the side opposite to the second opening 122 bends toward the direction closer to the second opening 122, or where both sides of the deformable part 21 bend toward the direction closer to the second opening 122. It is understood that the tangent point of the curved portion is between the two sides of the deformable part 21. Compared to a straight extension, the partially curved extension of the deformable part 21 makes it easier to deform, allowing the deformable part 21 to extend and retract more easily in the vertical direction, thereby more efficiently driving the sensing part 211 into or out of the sensing area 1221.

[0045] In some embodiments, such as Figure 6 and Figure 7 As shown, the mounting groove 12 is disposed adjacent to the upper surface of the material box 1, and the first opening 121 is located at the edge 11 of the upper surface of the material box 1. Both the first opening 121 and the second opening 122 are spaced at a preset distance from the outer edge of the upper surface. This preset distance represents the minimum straight-line distance between the first opening 121 and the second opening 122 and the outer edge 13 of the upper surface. The outer edge 13 of the upper surface is the edge that forms the upper surface of the material box and is located on the outer contour of the material box 1. Specifically, the distance between the first opening 121 and the outer edge 13 of the upper surface is defined as L1, and the distance between the second opening 122 and the edge 11 of the upper surface is defined as L2. It can be understood that L1 ≠ 0 and L2 ≠ 0. In some possible implementations, 4mm≤L1≤8mm and 2mm≤L2≤6mm are used to maintain a certain structural strength in the portion between the first opening 121 and the second opening 122 and the outer edge 13, while keeping the distance between the mounting groove 12 and the outer edge 13 small, so as to facilitate the abutment portion 22 protruding out of the edge 11 and pressing into the mounting groove 12.

[0046] In some embodiments, such as Figure 3 and Figure 6 As shown, the material box 1 includes a body 14 and a base 15. The body 14 is provided with a receiving cavity 141 for storing goods, and an upper opening 142 communicating with the receiving cavity 141 is opened at the upper end of the body 14. The base 15 is located at the lower end of the body 14. It can be understood that the upper edge of the body 14 is the edge of the upper surface of the material box 1, and the lower edge of the base 15 is the edge 11 of the lower surface of the material box 1.

[0047] For ease of reference, Figure 3 The top view shows a perspective view of the base 15. (Example) Figure 3 and Figure 8 As shown, in the top view of the material bin 1, the outer edge of the base 15 is spaced from the outer edge of the upper opening 142 by a preset value X (refer to...). Figure 8This arrangement allows the base 15 of one hopper 1 to nest within the upper opening 142 of another hopper 1, thus stacking two hopper sets. It should be noted that the preset value X is within the range of [0, 0.5 mm], meaning that in the top view, the distance X between the outer edge of the base 15 and the outer edge forming the upper opening 142 is greater than or equal to 0 and less than or equal to 0.5 mm. In other words, the two adjacent hopper sets partially overlap in the height direction to form a nested portion. When the hoppers 1 are stacked into a hopper set, the base 15 of the upper hopper 1 is within the nested portion. In this way, the lower hopper 1b in the two adjacent hopper sets can restrict the position of the base 15 of the upper hopper 1a, reducing the possibility of the two adjacent hopper sets being vibrated or deviating during movement, and improving the stability of the hopper set. In addition, since the two adjacent layers of bins 1 partially overlap in the height direction, the total height of the bin group is reduced compared to the implementation where the two adjacent layers of bins 1 only touch but do not overlap in the height direction, which is beneficial to increasing the storage capacity of warehouses and other storage locations.

[0048] In some embodiments, such as Figure 6 As shown, the lower edge of the body 14 protrudes horizontally from the outer edge of the base 15 to abut against the upper surface of the other hopper 1. That is, in the top view, the outer diameter of the body 14 is larger than the outer diameter of the base 15 (see reference). Figure 3 This creates a stepped surface 143 extending horizontally at the connection between the body 14 and the base 15. It can be understood that the stepped surface 143 at the connection between the body 14 and the base 15 is also the position where two adjacent material boxes 1 abut against each other after being nested. The mounting groove 12 is adjacent to the lower surface of the body 14, and the first opening 121 is located at the edge 11 of the lower surface of the body 14, i.e., the first opening 121 is formed on the stepped surface 143. The status detection element 2 protrudes from the stepped surface 143 through the first opening 121. The stepped surface 143 is planar, which facilitates both the nesting of two adjacent material boxes 1 and the installation of the status detection element 2 above the stepped surface 143.

[0049] In some possible implementations, the free end of the status detection element 2 for receiving pressure can protrude between the lower end face of the body 14 and the lower end face of the base 15 via the stepped surface 143. In this way, the status detection element 2 in the free state does not protrude from both ends of the material box 1 in the vertical direction, but is always located within the height range of the material box 1. This reduces the possibility of the status detection element 2 being easily accidentally touched due to protruding from the upper or lower end of the material box 1, which helps to extend the service life of the status detection element 2 and also improves the accuracy of the status detection element 2 in feeding back the stacking status.

[0050] This utility model embodiment provides a cargo status detection system, such as Figure 1As shown, the cargo status detection device 2 includes the cargo storage device 10 mentioned above, and thus has the same technical effect as the cargo storage device 10 mentioned above. That is, it can intuitively reflect the stacking status of two adjacent layers of bins 1, and can interrupt the positional deviation caused by the deviation of two adjacent layers of bins 1 in a timely manner. This reduces the possibility that the positional deviation will gradually accumulate in the upper layer of bins 1a during the formation of the bin group, improves the stability of the bin group and the reliability of stacking, and reduces the possibility of the bin group tipping over.

[0051] The cargo status detection system also includes a sensing device 20, which is used to detect the position of the aforementioned status detection element 2. The sensing device 20 can be a wired sensor connected to a cable or a wireless sensor without a cable. For example, the sensing device 20 can be a photoelectric sensor. The installation position of the sensing device 20 is related to the stacking position of the material bins 1. It can be understood that the position of the sensing device 20 is near the stacking position of two adjacent material bins 1. Specifically, "near the stacking position" means above or below the stacking position. It should be noted that in the embodiment where two adjacent stacked material bins are nested, the step surface 143 of the upper material bin 1a (or the upper edge of the body 14 of the lower material bin 1b) represents the aforementioned "stacking position". When the sensing device 20 is set as a photoelectric sensor, the height of the sensing device 20 is consistent with the height of the sensing part (such as the sensing part 211) in the status detection element 2 in the first state.

[0052] In some embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, the number of sensing devices 20 and status detection elements 2 are the same. Each sensing device 20 generates stacking status information based on the positions of all status detection elements 2 at the stacking positions of two adjacent material boxes. When all sensing devices 20 detect the status detection elements 2 in the first state, it indicates that the two adjacent material boxes 1 have been successfully stacked. The combined action of all status detection elements 2 can provide intuitive feedback on the position of each side of the material box 1, and can more reliably and accurately reflect the stacking status of two adjacent material boxes 1, so as to interrupt the positional deviation caused by the deviation between the two adjacent material boxes 1 in a timely manner.

[0053] Specifically, since multiple status detection elements 2 are installed on the same material bin 1, if a deviation occurs on one side of the material bin 1, this positional deviation will accumulate in the status detection elements 2 on other sides of the material bin 1, for example, in Figure 1 In the middle, each side of the material bin 1 is equipped with a status detection element 2. The upper material bin 1a and the lower material bin 1b are nested. If the upper material bin 1a deviates to the right by W1 relative to the lower material bin 1b, and W1 is greater than the distance W of the single-sided step surface 143 (refer to...), Figure 6If the front, rear, and right side status detection elements 2 are all shifted to the right by a distance W1, the right side of the base 15 will move outside the area where the upper opening 142 is located and cannot be nested into the upper opening 142, thus creating a gap between the right side step surface 143 of the material box 1 and the lower material box 1b, and will not be able to press against the status detection element 2. Therefore, among the status detection elements 2 located on the front, rear, and right sides, at least the right side status detection element 2 cannot be pressed into the mounting groove 12, so the sensing part 211 cannot enter the sensing area 1221 and cannot be detected by the sensing device 20. The nesting of two adjacent material boxes 1 fails, and the conveying device will not continue to perform the stacking action of the next material box 1.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
