Description

Technical Field

[0001] The present invention relates to the technical field of unmanned logistics, and in particular to an automatically adjustable intelligent shelf, a cargo storage method thereof, and an unmanned logistics system. Background Art

[0002] Unmanned logistics systems require frequent storage, transportation, and sorting of shelves. The storage capacity of the shelves determines the storage capacity of the unmanned logistics system to a certain extent. Whether the location of goods on the shelves can be accurately known determines the efficiency of storing and retrieving goods to a certain extent.

[0003] Existing shelves use fixed-layer shelves.

[0012] Furthermore, the first distance detector is also used to detect the distance between the first movable shelf layer and the shelf outer frame and feed it back to the control unit, and the second distance detector is also used to detect the distance between the second movable shelf layer and the shelf outer frame and feed it back to the control unit.

[0013] Furthermore, the number of the first movable shelf layer and / or the second movable shelf layer is one or at least two.

[0014] The present invention also provides a method for storing goods on the above-mentioned automatically adjustable smart shelf, which comprises:

[0015] Determine whether there is a suitable allocated area. If so, release the goods in the allocated area; if not, release the goods in the unallocated area.

[0016] Furthermore, the unallocated area is located on the diagonal line of the allocated area.

[0017] Furthermore, the criterion for determining whether there is a suitable allocated area is: if the size of the allocated area is larger than the size of the goods and the size difference is larger than a preset qualified distance, then it is determined to be yes; otherwise, it is determined to be no.

[0018] Furthermore, the preset qualified distance is 20 cm.

[0019] Furthermore, it also includes a moving step after placing the goods in the unallocated area: the control unit controls the first mobile shelf layer and the second mobile shelf layer to move along the first direction and the second direction respectively, until the first mobile shelf layer and the second mobile shelf layer move to a position at a preset distance from the goods.

[0020] Furthermore, the preset distance is 10 cm.

[0021] Furthermore, it also includes a judgment execution step after the moving step: if the shelf is full, the loading is completed; if the shelf is not full, it returns to determine whether there is a suitable allocated area.

[0022] Furthermore, it also includes a judgment execution step after placing the goods in the allocated area: if the shelf is full, the loading is completed; if the shelf is not full, it returns to determine whether there is a suitable allocated area.

[0030] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments.

[0031] The specific embodiments of the present invention are intended to facilitate further explanation of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions, and the technical effects brought about. It should be noted that the description of these embodiments does not constitute a limitation of the present invention. In addition, the technical features involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] In an exemplary embodiment of the present invention, the automatic adjustment of the smart shelf is as follows: Figure 1As shown, the automatically adjustable intelligent shelf includes a shelf frame 1 and a control unit 2. The shelf frame 1 is provided with a first movable shelf layer 4 and a second movable shelf layer 3 which can be independently moved along the intersecting first direction and second direction respectively. The control unit 2 can control the first movable shelf layer 4 and the second movable shelf layer 3 to move along the first direction and the second direction respectively to form storage spaces of different sizes for storing goods of different specifications.

[0033] In this exemplary embodiment, by arranging the first movable shelf layer 4 and the second movable shelf layer 3 that can be independently moved along the first and second directions intersecting each other in the shelf outer frame 1, the control unit 2 can control the first movable shelf layer 4 and the second movable shelf layer 3 to move along the first direction and the second direction respectively, and by using the dynamically adjustable shelf layers, the maximum amount of storage of goods of different specifications in the same shelf is achieved, effectively improving the shelf storage capacity. Figure 1 As shown, the first movable shelf layer 4 and / or the second movable shelf layer 3 are one or at least two, so that the shelf can be divided into a plurality of grid areas for storing goods according to actual needs. The first movable shelf layer 4 and the second movable shelf layer 3 are preferably formed by a plurality of rods, and the shelf layer formed by the rods can avoid mutual interference between the first movable shelf layer 4 and the second movable shelf layer 3 when moving, thereby ensuring the stability of movement.

[0034] In this embodiment, as long as the first direction and the second direction are arranged crosswise, the dynamically adjustable shelf layer can be realized. Figure 1 As shown, the first direction is the horizontal direction, the second direction is the vertical direction, the first movable shelf layer 4 is vertically arranged, and the second movable shelf layer 3 is horizontally arranged, which is conducive to the stable placement of goods.

[0035] As to how to realize the movement of the first movable shelf layer 4 and the second movable shelf layer 3, in a preferred embodiment, as Figure 1 As shown, the inner side of the shelf outer frame 1 is provided with a movable guide rail for the first movable shelf layer 4 and the second movable shelf layer 3 to move. Such a structural form is simple in structure and easy to implement, and has high feasibility. In the embodiment where the first movable shelf layer 4 and the second movable shelf layer 3 are both formed by a plurality of rods, in order to make the structure simple and the movement stable, as shown in FIG. Figure 1 As shown, both ends of the plurality of rods are preferably connected to the movable guide rails of the shelf outer frame 1 .

[0036] In order to further improve the moving stability performance of the first mobile shelf layer 4 and the second mobile shelf layer 3, as Figure 1As shown, the shelf outer frame 1 is provided with second guide rails 5 for movement of the second movable shelf layer 3 on both sides corresponding to the first movable shelf layer 4, and the shelf outer frame 1 is provided with first guide rails 6 for movement of the first movable shelf layer 4 on both sides corresponding to the second movable shelf layer 3.

[0037] In order to facilitate the control unit 2 to control the moving distances of the first movable shelf layer 4 and the second movable shelf layer 3 to form storage spaces of different sizes, in a preferred embodiment, as shown in FIG. Figure 1 As shown, the first movable shelf layer 4 is provided with a first distance detector 8 for detecting the distance between the first movable shelf layer 4 and the goods and feeding it back to the control unit 2, and the second movable shelf layer 3 is provided with a second distance detector 7 for detecting the distance between the second movable shelf layer 3 and the goods and feeding it back to the control unit 2. Further, the first distance detector 8 is also used to detect the distance between the first movable shelf layer 4 and the shelf outer frame 1 and feed it back to the control unit 2, and the second distance detector 7 is also used to detect the distance between the second movable shelf layer 3 and the shelf outer frame 1 and feed it back to the control unit 2. In this way, the control unit 2 can obtain the accurate position of each cargo according to the distance between the first movable shelf layer 4 and the second movable shelf layer 3 relative to the shelf outer frame 1, which facilitates the rapid storage and retrieval of the cargo.

[0038] Since the moving distance of each shelf is recorded in the control unit 2, the control unit 2 can know the specific location of each item of goods, thus completing the dynamically adjusted goods storage and obtaining the precise location of each item, serving the rapid access in the unmanned logistics system.

[0039] Correspondingly, the present invention also provides a method for storing goods on the above-mentioned automatic adjustment intelligent shelf, Figure 2 As shown, the method includes:

[0040] Determine whether there is a suitable allocated area. If so, release the goods in the allocated area; if not, release the goods in the unallocated area.

[0041] In this method, by giving priority to placing goods in the allocated area, if the goods cannot be placed in the allocated area, then placing goods in the unallocated area, this can improve the utilization rate of each area of ​​the shelf. Figure 1 As shown, the unallocated area is located on the diagonal line of the allocated area. It is not restricted by the length and width of the allocated area and new goods can be placed freely.

[0042] Specifically or preferably, the criterion for determining whether there is a suitable allocated area is: if the size of the allocated area is larger than the size of the goods and the size difference is larger than the preset qualified distance, then it is determined to be yes, otherwise, it is determined to be no. This can ensure that the goods are placed safely and avoid damage to the goods caused by space limitations. Specifically or preferably, the preset qualified distance is 20 cm.

[0043] During the storage process, the above-mentioned cargo storage method also includes a judgment execution step after placing the cargo in the allocated area: if the shelf is full, the loading is completed; if the shelf is not full, it returns to determine whether there is a suitable allocated area.

[0044] The cargo storage method preferably further includes a moving step after placing the cargo in the unallocated area: the control unit 2 controls the first movable shelf layer 4 and the second movable shelf layer 3 to move in the first direction and the second direction respectively, until the first movable shelf layer 4 and the second movable shelf layer 3 move to a position at a preset distance from the cargo. Moving the first movable shelf layer 4 and the second movable shelf layer 3 to a suitable distance can form a suitable storage area, further improving space utilization. Specifically or preferably, the preset distance is 10 cm.

[0045] During the storage process, the above-mentioned cargo storage method further includes a judgment execution step after the moving step: if the shelf is full, the loading is completed; if the shelf is not full, it returns to determine whether there is a suitable allocated area.

[0046] Below Figure 1 The embodiment shown is taken as an example and the cargo storage method of the present invention is combined to explain the cargo storage process as follows:

[0047] The initial state of the shelf is that the second movable shelf layer 3 is stacked on the top layer, and the first movable shelf layer 4 is stacked on the far right. When placing goods on the shelf, start from the lower left corner. When the first goods are placed, the control unit 2 controls the first movable shelf layer 4 and the second movable shelf layer 3 to start moving, and the first distance detector 8 and the second distance detector 7 of the shelf layer start working. When the distance to the goods is detected to be 10cm, the control unit 2 records the moving distance of the first movable shelf layer 4 and the second movable shelf layer 3, and the placement of the first goods is completed.

[0048] The second cargo is placed in an area determined by its size. If the length or width can be placed in the horizontal and vertical columns (i.e., the allocated area) formed by the first cargo, it is placed. Otherwise, it is placed in the designated area on the diagonal (i.e., the unallocated area). Like the first cargo, the control unit 2 controls the first movable shelf layer 4 and the second movable shelf layer 3 to start moving, and the first distance detector 8 and the second distance detector 7 of the shelf layer start working and record the moving distance.

[0049] So far, the area to be divided and the divided areas of different sizes have been formed. From now on, each cargo will be placed in the allocated area first if it can match the divided area (the length and width of the cargo is not less than 20cm of the divided area to avoid the situation of placing small cargo in a large box). If it cannot match, it will be placed in the unallocated area, and a new unallocated area will be formed. When all areas have been divided, the divided areas will be filled in order according to the matching degree between the cargo and the divided blocks.

[0050] The present invention also provides an unmanned logistics system, which includes the above-mentioned automatic adjustment smart shelf. The unmanned logistics system can be applicable to unmanned warehousing, unmanned transport vehicles, unmanned personnel circulation stations, unmanned distribution stations, unmanned vehicles and drones. Since the automatic adjustment smart shelf of the present invention can make full use of the shelf space, the storage capacity of the shelf is improved. Accordingly, the unmanned logistics system of the present invention also has the above-mentioned beneficial technical effects, which will not be repeated here.

[0051] The above combined embodiments are used to describe the embodiments of the present invention in detail, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, equivalent substitutions and variations to these embodiments without departing from the principles and essential spirit of the present invention are still within the scope of protection of the present invention.
