Description

Technical Field

[0001] The present invention relates to the field of shelves, and particularly to a four-sided warehouse for intelligent logistics warehousing. Background Art

[0002] At present, there is a circular warehouse, or annular warehouse, in the field of goods warehousing. From a top-down perspective, the shelves are arranged in a ring shape, and a manipulator is provided at the geometric center of the ring. The manipulator realizes logistics warehousing by picking up and placing goods on the circular warehouse. However, the circular warehouse occupies a large area and is irregular. Especially when several circular warehouses need to be centrally arranged, the utilization rate of the overall surface area is low. Summary of the Invention

[0003] The problem to be solved by the present invention is to provide a four-sided warehouse for intelligent logistics warehousing, which is superior to the circular warehouse in terms of overall cost, structural stability, area utilization rate, flexibility of the shape and size of goods (i.e., the placement position of goods), flexibility of import and export settings, etc. without affecting the material warehousing efficiency, and is convenient to be used adjacent to many similar four-sided warehouses.

[0004] To solve the above problems, the present invention provides a four-sided warehouse for intelligent logistics warehousing. To achieve the above object, the technical solution adopted by the present invention to solve its technical problems is:

[0005] A four-sided warehouse for intelligent logistics warehousing includes: four side storage areas; four corner storage areas, which are arranged alternately and at intervals with the side storage areas, and the corner storage areas are arranged at an angle with the adjacent side storage areas; from a top-down perspective, the side storage areas and the corner storage areas enclose a chamfered rectangle, the horizontal length of a single side storage area is greater than the horizontal length of a single corner storage area, and the side storage areas and the corner storage areas have several layers vertically for placing goods.

[0006] The beneficial effects of adopting the above technical solution are: Goods can be placed in both the side storage areas and the corner storage areas, with high space utilization rate. It is convenient to arrange a manipulator in the inner circle of the side storage areas and the corner storage areas, and the manipulator realizes the picking up of goods. The shape feature of the chamfered rectangle is close to a rectangle rather than a regular octagon, but it has stronger structural strength.

[0007] The circular library in the prior art is designed to facilitate the movement of the manipulator in the center, and all designs serve the manipulator, which brings disadvantages in other fields. Compared with the circular library, when many storage libraries need to be arranged in an array, for the same diameter circular library and the square library with the same side length, the total perimeter of the circular library is shorter, and the corresponding positions for storing goods are relatively fewer. The square library has more storage space for goods than the circular library. The square library can use crossbeams with longer dimensions. The length of a single profile used in the circular library is short, and there are many points that need to be butt-jointed, which increases the overall assembly workload and is also likely to reduce the overall structural strength. Or the circular library needs to use arc-shaped beams, which are costly. The square library has long straight edges, which is convenient for matching with external linear assembly lines. There is no need for a circular assembly line. The linear assembly line has relatively low costs and reliable quality.

[0008] The square library compared with the circular library is not just a simple change in geometric shape. This overcomes the technical prejudice in this field because the shelf designs in this field often serve manipulators with higher technical integration. Although the circular library can ensure that the radial distances from the manipulator to each point on the circular library are equal, with the powerful degrees of freedom of modern manipulators and the help of automatic control programs, the benefits brought by the advantage of equal radial distances from the circular library to the manipulator are quite limited. Modern manipulators can still quickly pick up and place goods from the square library in this application. At the same time, the square library has advantages over the circular library in terms of overall cost, structural stability, area utilization rate, etc. More importantly, it is convenient to be used adjacent to many similar square libraries.

[0009] Since the horizontal space on each layer of the side storage area is large, compared with the circular library, the flexibility of the shape and size of goods and the placement position of stored items is higher, and the import and export settings of the square library are also more flexible. The chamfered rectangular square library has its side storage area facing the manipulator, which is convenient for the manipulator to grab.

[0010] Relatively large-sized goods can be stored in the side storage area, and the specific position where the goods are placed in the local part of the side storage area is also flexible. Existing circular libraries are often surrounded by small identical-sized grids, which are not suitable for storing large-sized goods.

[0011] As a further improvement of the present invention, in the same plane, each corner storage area includes an inner corner crossbeam located in the inner circle and an outer corner crossbeam located in the outer circle. The length of the inner corner crossbeam is shorter than that of the outer corner crossbeam and they are parallel to each other. Each corner storage area also includes two connecting beams perpendicular to each other. The inner corner crossbeam, the outer corner crossbeam, and the connecting beams enclose an isosceles trapezoid.

[0012] The beneficial effects of adopting the above technical solution are as follows: The chamfers at the four corners form a structure of an isosceles trapezoid. The isosceles trapezoid has the characteristic of stable structure compared with a parallelogram, which also plays a role in stabilizing the structure for the adjacent side storage areas and is more stable than simple rectangular or cuboid shelves.

[0013] As a further improvement of the present invention, in the same plane, each edge storage area includes an inner edge beam located in the inner circle and an outer edge beam located in the outer circle, the inner edge beam and the outer edge beam are parallel to each other and have equal lengths, and each edge storage area also includes two parallel connecting beams, and the inner edge beam, the outer edge beam, and the connecting beams form a rectangle.

[0014] The beneficial effect of adopting the above technical solution is that the side storage area is composed of beams connected vertically to each other, which is easy to manufacture and convenient for storing a large amount of goods.

[0015] As a further improvement of the present invention, the included angle between the side inner cross beam and the adjacent corner inner cross beam is 135°, the two ends of the connecting beam are respectively connected to vertical inner columns and outer columns, and the bottoms of the inner columns and outer columns are provided with footrests.

[0016] The beneficial effect of adopting the above technical solution is that each corner storage area has the same shape, and the direction of the corner storage area is to converge on the geometric center of the square warehouse, which is convenient for the robot to pick up and place the goods.

[0017] As a further improvement of the present invention, the length of the side inner cross beam is four times the length of the corner inner cross beam.

[0018] The beneficial effect of adopting the above technical solution is that the main body of the shelf is composed of the side storage area, the storage capacity of the side storage area is exactly four times that of the corner storage area, and the storage capacity of the corner storage area is determined by the length of the inner cross beam of the corner, making full use of the length of the inner cross beam of the side and the inner cross beam of the corner.

[0019] As a further improvement of the present invention, an intermediate beam is provided in parallel between the inner side beam and the outer side beam.

[0020] The beneficial effect of adopting the above technical solution is: since the width of the side storage area is wider than that of the corner storage area, the middle beam improves the vertical bearing capacity of the side storage area and facilitates the placement of smaller-sized goods.

[0021] As a further improvement of the present invention, the edge storage area and the corner storage area are provided with a plurality of rollers, the axial direction of the rollers themselves is parallel to the horizontal length direction of the edge storage area or the corner storage area, and the inner corner beam and the inner side beam are provided with rollers extending toward the inner circle on the side away from the outer corner beam and the outer side beam.

[0022] The beneficial effect of adopting the above technical solution is that the sliding friction provided by the roller is small, which makes it convenient for the manipulator to store and take the goods on the shelf.

[0023] As a further improvement of the present invention, the cross-sectional profile of the inner column is a quadrilateral, which is an axisymmetric figure and not a central symmetric figure. The inner column includes a first flat plate and a second flat plate that are adjacent and form an angle of 45°, and also includes a third flat plate and a fourth flat plate that are adjacent and form an angle of 135°.

[0024] The beneficial effects of adopting the above technical solution are: only the inner column needs to be of a special shape, while the outer column can use profiles of conventional shapes, reducing the cost of parts and facilitating assembly.

[0025] As a further improvement of the present invention, the first flat plate or the second flat plate is assembled with the inner corner cross beam, and the third flat plate and the fourth flat plate are assembled with the connecting beam.

[0026] The beneficial effects of adopting the above technical solution are: both the inner corner cross beam and the connecting beam are assembled perpendicular to the surface of the inner column. The assembly method is simple and reliable. At the same time, there will be no situation where two adjacent flat plates on the inner column are both assembled with external components, reducing the number of drilled holes and ensuring the overall structural strength of the inner column.

[0027] As a further improvement of the present invention, the corner storage area is the entrance of the goods, and the side storage area is the exit of the goods.

[0028] The beneficial effects of adopting the above technical solution are: the long and straight side storage area as the exit is convenient for matching with a straight-line production line, the entry and exit of goods are separated, and the material efficiency is high.

Specific embodiments

[0037] The following further elaborates on the content of the present invention in conjunction with specific embodiments:

[0038] To achieve the object of the present invention, a four - sided warehouse for intelligent logistics warehousing includes: four side storage areas 2; four corner storage areas 1, with the four corner storage areas 1 and the side storage areas 2 arranged alternately at intervals, and the corner storage areas 1 and the adjacent side storage areas 2 arranged at an included angle; from a top - down perspective, the side storage areas 2 and the corner storage areas 1 enclose a chamfered rectangle, the horizontal length of a single side storage area 2 is greater than the horizontal length of a single corner storage area 1, and the side storage areas 2 and the corner storage areas 1 have several layers vertically for placing goods 12.

[0039] Figure 1 、 Figure 2 The goods 12 are hidden in... As Figure 1 、 Figure 3 As shown, a manipulator 13 is provided at the geometric center of the chamfered rectangle enclosed by the side storage areas 2 and the corner storage areas 1. The number of layers of the corner storage areas 1 and the side storage areas 2 in the vertical direction is several and equal to each other.

[0040] The overall vertical number of layers of the four - sided warehouse is not fixed, and its height only needs to match the lowest and highest vertical movement degrees of freedom of the manipulator 3.

[0041] The beneficial effects of adopting the above - mentioned technical solution are as follows: Goods can be placed in both the side storage areas and the corner storage areas, with high space utilization rate. It is convenient to arrange the manipulator in the inner circle of the side storage areas and the corner storage areas, and the manipulator realizes the picking of goods. The shape feature of the chamfered rectangle is close to a rectangle rather than a regular octagon, but has stronger structural strength.

[0042] The circular library in the prior art is designed to facilitate the movement of the manipulator in the center, and all designs serve the manipulator, thus bringing disadvantages in other fields. Compared with the circular library, when many storage libraries need to be arranged in an array, for a circular library with the same diameter, the total perimeter is shorter than that of a square library with the same side length. Correspondingly, the number of positions where goods can be stored is relatively less, and the goods storage space of the square library is larger than that of the circular library. The square library can use crossbeams with longer dimensions. The length of a single profile used in the circular library is short, and there are many connection points, which increases the overall assembly workload and is also likely to reduce the overall structural strength. Or the circular library needs to use arc-shaped beams, which are costly. The square library has long straight sides, which is convenient for matching with external linear assembly lines. There is no need for a circular assembly line. The linear assembly line has relatively low costs and reliable quality.

[0043] The square library is not just a simple change in geometric shape compared with the circular library. This overcomes the technical prejudice in this field because the shelf designs in this field often serve manipulators with higher technology integration. Although the circular library can achieve equal radial distances from the manipulator to each point on the circular library, with the powerful degrees of freedom of modern manipulators and the help of automatic control programs, the benefits brought by the advantage of equal radial distances from the circular library to the manipulator are quite limited. Modern manipulators can still quickly pick up and place goods from the square library in this application. At the same time, the square library has advantages over the circular library in terms of overall cost, structural stability, area utilization rate, etc. More importantly, it is convenient to be used adjacent to many similar square libraries.

[0044] In some other embodiments of the present invention, along the direction from the inner circle to the outer circle of the square library, at least one row of goods 12 is provided at the same horizontal height.

[0045] As Figure 3 shown, in one embodiment, the goods 12 are arranged in two rows.

[0046] The beneficial effects of adopting the above technical solution are as follows: The goods at the same horizontal height can be arranged in two inner and outer circles, or even more. Only the manipulator needs to increase some horizontal telescopic feed amounts when picking up and placing goods, but the storage capacity of the goods can be increased several times. The square library itself can be composed of assembled profiles or welded.

[0047] In some other embodiments of the present invention, within the same plane, each corner storage area 1 includes an inner corner crossbeam 6 located in the inner circle and an outer corner crossbeam 5 located in the outer circle. The length of the inner corner crossbeam 6 is shorter than that of the outer corner crossbeam 5 and they are parallel to each other. Each corner storage area 1 further includes two connecting beams 9 that are perpendicular to each other. The inner corner crossbeam 6, the outer corner crossbeam 5, and the connecting beam 9 enclose an isosceles trapezoid.

[0048] The beneficial effects of adopting the above technical solution are as follows: The chamfers at the four corners form an isosceles trapezoid structure. Compared with a parallelogram, the isosceles trapezoid has the inherent characteristic of a stable structure, which also plays a role in stabilizing the structure of the adjacent side storage areas and is more stable than a simple rectangular or cuboid shelf.

[0049] In some other embodiments of the present invention, in the same plane, each side storage area 2 includes an inner side cross beam 8 located in the inner circle and an outer side cross beam 7 located in the outer circle. The inner side cross beam 8 and the outer side cross beam 7 are parallel to each other and have the same length. Each side storage area 2 further includes two parallel connecting beams 9. The inner side cross beam 8, the outer side cross beam 7, and the connecting beam 9 enclose a rectangle.

[0050] The beneficial effects of adopting the above technical solution are as follows: The side storage areas are composed of beams connected perpendicularly to each other, which is convenient for manufacturing and convenient for storing a large amount of goods.

[0051] In some other embodiments of the present invention, the included angle between the inner side cross beam 8 and the adjacent inner corner cross beam 6 is 135°. The two ends of the connecting beam 9 are respectively connected with vertical inner columns 4 and outer columns 3, and the bottoms of the inner columns and the outer columns are provided with foot seats.

[0052] The beneficial effects of adopting the above technical solution are as follows: It makes each corner storage area have the same shape, and the orientation of the corner storage area converges to the geometric center of the four-way warehouse, which is convenient for cooperating with a manipulator to pick up and place goods.

[0053] In some other embodiments of the present invention, the length of the inner side cross beam 8 is four times the length of the inner corner cross beam 6.

[0054] The beneficial effects of adopting the above technical solution are as follows: The shelf main body is composed of side storage areas. The storage capacity of the side storage area is exactly four times that of the corner storage area. The storage capacity of the corner storage area is determined by the length of the inner corner cross beam, making full use of the lengths of the inner side cross beam and the inner corner cross beam.

[0055] In some other embodiments of the present invention, an intermediate beam 10 is also parallelly provided between the inner side cross beam 8 and the outer side cross beam 7.

[0056] The beneficial effects of adopting the above technical solution are as follows: Since the width of the side storage area is wider than that of the corner storage area, the intermediate beam improves the vertical bearing capacity of the side storage area and is also convenient for placing goods of smaller sizes. The intermediate beam 10, the inner side cross beam 8, and the outer side cross beam 7 form three parallel horizontal beams, making it possible to arrange two rows of goods 12 at the same horizontal height. In fact, the number of horizontal beams parallelly provided in each of the corner storage area 1 and the side storage area 2 is not limited.

[0057] In some other embodiments of the present invention, such as Figure 1As shown in the figure, a plurality of rollers 11 are provided in the side storage area 2 and the corner storage area 1. The axial direction of the rollers 11 is parallel to the horizontal length direction of the corresponding side storage area 2 or corner storage area 1. The inner corner cross beam 6 and the inner side cross beam 8 are provided with rollers 11 extending inwardly on the side away from the outer corner cross beam 5 and the outer side cross beam 7. For reasons of view expression, Figure 1 only the top layer of rollers 11 is also shown in the figure.

[0058] The bottom surface of the goods 12 contacts the rollers 11, and the manipulator 13 contacts and adsorbs the side vertical surface of the goods 12 through a suction cup, driving the goods 12 to slide on the rollers 11, thereby realizing the picking and placing of the goods 12.

[0059] The beneficial effect of adopting the above technical solution is that the sliding friction provided by the rollers is small, which is convenient for the manipulator to store and pick up the goods on the shelf.

[0060] In some other embodiments of the present invention, the cross-sectional profile of the inner column 4 is a quadrilateral, the quadrilateral is an axisymmetric figure and not a centrosymmetric figure. The inner column 4 includes a first flat plate 4a and a second flat plate 4b that are adjacent and have an included angle of 45°, and also includes a third flat plate 4c and a fourth flat plate 4d that are adjacent and have an included angle of 135°.

[0061] As Figure 5 shown in the figure, the first flat plate 4a is adjacent and perpendicular to the third flat plate 4c, and the second flat plate 4b is adjacent and perpendicular to the fourth flat plate 4d.

[0062] The beneficial effect of adopting the above technical solution is that only the inner column needs to be of a special shape, while the outer column can use profiles of conventional shapes, reducing the cost of parts and facilitating assembly.

[0063] In some other embodiments of the present invention, the first flat plate 4a or the second flat plate 4b is assembled with the inner corner cross beam 6, and the third flat plate 4c and the fourth flat plate 4d are assembled with the connecting beam 9.

[0064] The beneficial effect of adopting the above technical solution is that both the inner corner cross beam and the connecting beam are assembled perpendicular to the surface of the inner column. The assembly method is simple and reliable. At the same time, there will be no situation where two adjacent flat plates on the inner column are both assembled with external components, reducing the number of holes drilled and ensuring the overall structural strength of the inner column.

[0065] In some other embodiments of the present invention, the outlet and inlet of the goods 12 can be set at any position in the corner storage area 1 or the side storage area 2.

[0066] Preferably, the corner storage area 1 is the inlet of the goods 12, and the top layer of the side storage area 2 is the outlet of the goods 12.

[0067] The beneficial effects of adopting the above technical solution are as follows: The long and straight side storage area serves as an exit, which is convenient for matching with a straight-line production line. The incoming and outgoing of goods are separated, and the material efficiency is high. The space utilization rate for storing goods at the corner storage area is relatively lower than that of the side storage area, so it is suitable as an entrance.

[0068] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention. The purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it. However, it cannot be used to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
