Abstract
Description
Technical Field
[0001] This application relates to the field of warehousing and logistics conveying equipment technology, and in particular to a turnover box depalletizing and palletizing device and warehousing system. Background Technology
[0002] Turnover boxes are components in a warehousing system used for the turnover and storage of goods.
[0003] In existing technologies, such as Figure 1 As shown, five tote boxes are stacked in a single layer on a pallet. When goods enter the warehouse, the designated goods are placed in the tote boxes, and the conveyor line transports the tote boxes to the designated storage location. A robotic arm then stacks these tote boxes onto the pallet. When goods leave the warehouse, the robotic arm transfers the tote boxes from the pallet to the conveyor line, which then transports the tote boxes to the designated location for goods picking.
[0004] Because the robotic arm can only grab one tote at a time and place it on the conveyor line, the efficiency of unpacking and palletizing tote boxes is low and cannot meet the demand. Utility Model Content

The mounting base is circumferentially arranged with multiple clamping components, which are used to jointly clamp multiple turnover boxes in an entire layer to improve the transfer efficiency of the turnover boxes. In addition, each clamping component is provided with a turnover box limiting component, which is used to selectively engage with the turnover box to limit its movement and prevent the turnover boxes from falling due to insufficient clamping force when multiple clamping components are clamping multiple turnover boxes in an entire layer.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0043] Turnover containers are components in a warehousing system used for the turnover and storage of goods.
[0044] In existing technologies, such as Figure 1 As shown, five turnover boxes 'a' are stacked in a single layer on a pallet. When goods are received, the designated goods are placed in turnover boxes 'a', and the conveyor line transports the turnover boxes 'a' to the designated storage location. A robotic arm then stacks these turnover boxes 'a' sequentially onto the pallet. When goods are shipped out, the robotic arm transfers the turnover boxes 'a' sequentially from the pallet to the conveyor line, which then transports them to the designated location for goods picking.
[0045] Because the robotic arm can only pick up one tote box (a) at a time and place it on the conveyor line, the efficiency of unpacking and palletizing tote boxes (a) is low and cannot meet the demand.
[0046] To improve the efficiency of unpacking and palletizing turnover boxes, this application provides a turnover box unpacking and palletizing device. The solution provided by this application will be described in detail below with reference to the accompanying drawings.
[0047] Figure 1 This is a schematic diagram of the placement of turnover boxes in existing technology; Figure 2 This is a schematic diagram of the overall structure of the turnover box depalletizing and unpalletizing device provided in one embodiment of this application; Figure 3 yes Figure 1 A schematic diagram of the turnover box destacking and stacking device after removing the mounting base 100.
[0048] Reference Figures 1 to 3 As shown in the figure, this application embodiment provides a turnover box destacking and palletizing device, including a mounting base 100. Multiple clamping components 200 are arranged circumferentially on the mounting base 100. These clamping components 200 are used to jointly clamp multiple turnover boxes in an entire layer, thereby improving the transfer efficiency of the turnover boxes. In addition, each clamping component 200 is provided with a turnover box limiting component 300, which is used to selectively engage with the turnover box to limit its movement and prevent the turnover boxes from falling due to insufficient clamping force when multiple clamping components 200 are clamping multiple turnover boxes in an entire layer.
[0049] The mounting base 100 has a rectangular overall shape, with clamping components 200 on each of its four sides. These four clamping components 200 can be closed together to clamp the sides of the entire layer of turnover boxes, thus enabling the gripping of the entire layer of turnover boxes. (See details...) Figure 2 As shown, in some examples, the clamping assembly 200 includes a clamping drive assembly 210, a clamping guide assembly 220, and a clamping portion 230. The clamping guide assembly 220 is fixedly mounted on the mounting base 100 perpendicular to its side surface. The clamping portion 230 is connected to the clamping guide assembly 220, i.e., it is connected to the mounting base 100 via the clamping guide assembly 220. The clamping portion 230 can move along a direction perpendicular to the side surface of the mounting base 100 via the clamping guide assembly 220 to selectively clamp the side surface of the turnover box. The clamping drive assembly 210 connects the mounting base 100 and the clamping portion 230, and is used to drive the clamping portion 230 to move, thereby clamping the turnover box. Exemplarily, the clamping drive assembly 210 is fixedly mounted on the mounting base 100, and its movable portion is connected to the clamping portion 230. The clamping drive assembly 210 drives the clamping portion 230 to move by moving the movable portion. In some other examples, the clamping drive assembly 210 is fixedly mounted on the clamping part 230, and the movable end is connected to the mounting base 100. During operation, the clamping drive assembly 210 drives the clamping part 230 to move relative to the mounting base 100.
[0050] Preferably, a clamping guide component 220 is provided on each side of the clamping drive component 210 to ensure that the clamping part 230 can move stably when the clamping drive component 210 drives the clamping part 230 to move.
[0051] For example, the clamping drive assembly 210 can be a cylinder, an electric cylinder, or a lead screw and nut drive assembly. It is understood that the clamping drive assembly 210 can be any linear drive assembly; this is merely an example. The mounting base 100 can be a fixed mounting plate, with a component on its top for fixed connection with the robot arm. This connection component is prior art and will not be described in detail here. The clamping guide assembly 220 can be a linear guide rail or a linear guide rod assembly, both of which are prior art and will not be described in detail here.
[0052] To ensure the contact area between the clamping part 230 and the turnover box, the clamping part 230 can be configured as a clamping plate.
[0053] Reference Figure 2 As shown, in some examples, each clamping assembly 200 is provided with multiple turnover box limiting assemblies 300, which are evenly distributed on the clamping assembly 200. When the clamping assembly 200 clamps an entire layer of turnover boxes, the turnover box limiting assemblies 300 are all engaged with the side walls of the turnover boxes, which can keep the turnover boxes balanced and stable, ensuring that the turnover boxes will not fall during clamping and transfer.
[0054] For example, multiple turnover box limiting components 300 may be evenly distributed along the length direction of the clamping component 200. It should be noted that the length direction of the clamping component 200 can be referenced... Figure 2 The x-direction is shown in the figure.
[0055] Figure 4 This is a schematic diagram of the clamping component 200 and the turnover box limiting component 300 after assembly according to an embodiment of this application; Figure 5 yes Figure 4 A front view of the assembly of the clamping component 200 and the turnover box limiting component 300; Figure 6 This is a schematic diagram of the clamping component 200 and the turnover box limiting component 300 after assembly according to another embodiment of this application; Figure 7 yes Figure 6 The front view of the assembly of the clamping component 200 and the turnover box limiting component 300.
[0056] Reference Figures 2 to 7 As shown, in some examples, the turnover box limiting assembly 300 includes a base 310, a limiting guide assembly 320, a limiting drive assembly 330, and a limiting part 340. The base 310 is horizontally fixedly mounted on the clamping part 230 of the clamping assembly 200. The limiting guide assembly 320 is fixedly mounted on the base 310 in a direction perpendicular to the clamping part 230. The limiting part 340 is connected to the limiting guide assembly 320, i.e., the limiting part 340 is connected to the base 310 through the limiting guide assembly 320. The limiting drive assembly 330 is fixedly mounted on the base 310, and its movable end is connected to the limiting part 340. When the limiting drive assembly 330 is activated, the movable end moves, thereby driving the limiting part 340 to move, thus selectively engaging in the side edge of the turnover box to ensure that the turnover box does not fall.
[0057] Preferably, a limit guide component 320 is provided on each side of the limit drive component 330 to ensure that the limit part 340 can move smoothly when the limit drive component 330 drives the limit part 340 to move.
[0058] Continue to refer to Figures 4 to 7 As shown, in some examples, the clamping assembly 200 is provided with a space to accommodate the limiting portion 340. The limiting portion 340 can be accommodated within the clamping assembly 200 to prevent it from protruding from the surface of the limiting portion 340. This ensures that when clamping an entire layer of turnover boxes, the limiting portion 340 will not protrude from the surface of the clamping assembly 200 and affect the clamping of the turnover boxes.
[0059] like Figure 3 , Figure 5 and Figure 7As shown, the turnover box limiting assembly 300 also includes a limiting block 350, which is fixedly disposed on the side of the limiting part 340 facing the turnover box. The limiting block 350 is used to engage with the side of the turnover box. For example, the limiting block 350 is provided with a groove that mates with the side edge of the turnover box, so that the limiting block 350 can engage with the side edge of the turnover box to ensure stable clamping of the turnover box.
[0060] like Figure 5 and Figure 7 As shown, in some examples, the limiting part 340 has multiple limiting blocks 350 evenly distributed on the side facing the turnover box. The multiple limiting blocks 350 are evenly distributed in a rectangle or arranged vertically to ensure that the turnover box is fully limited and to prevent it from swinging.
[0061] Alternatively, for example, the limiting part 340 can be a limiting plate, which can provide a larger contact area and has a better limiting and clamping effect. Additionally, a groove can be provided on the limiting plate to mate with the side edge of the turnover box. The limiting drive assembly 330 can be configured as a cylinder, electric cylinder, or lead screw and nut drive assembly, or other linear drive assemblies, which will not be listed here. The limiting guide assembly 320 can be configured as a linear guide rail or guide rod assembly, both of which are prior art and will not be described in detail here.
[0062] Reference Figure 2 and Figure 7 As shown, the clamping assembly 200 is equipped with a photoelectric detection sensor 400 for detecting whether the turnover box has fallen. When the photoelectric detection sensor 400 detects that the turnover box has fallen, it sends a turnover box fall signal to the control system to ensure that the machine can be stopped in time.
[0063] Understandably, this depalletizing and palletizing device can be used for both depalletizing and palletizing turnover boxes. When transferring an entire layer of turnover boxes, firstly, all clamping components 200 move outwards. The robotic arm controls the palletizing device to move to the location of the entire layer of turnover boxes. Once the entire layer is positioned between the opposing clamping components 200, all clamping components 200 move inwards until they are clamped against the side wall of the turnover box. Then, the limit drive component 330 drives the limit part 340 to move inwards and engage with the side wall of the turnover box. Finally, the robotic arm uses the palletizing device to transfer the entire layer of turnover boxes to the designated location.
[0064] Secondly, embodiments of this application provide a warehousing system, including a robotic arm, a tote conveyor line, a tote placement pallet, and a tote depalletizing / unpalletizing device as described in any of the first aspects. The tote depalletizing / unpalletizing device is mounted on the robotic arm, which uses this device to move multiple tote boxes in an entire layer from the tote conveyor line to the tote placement pallet; or, from the tote placement pallet to the tote conveyor line. Since this warehousing system includes the tote depalletizing / unpalletizing device of any of the above-described technical solutions, it possesses all the beneficial effects of the tote depalletizing / unpalletizing device of any of the above-described technical solutions, which will not be elaborated further here.
[0065] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.
[0066] The above detailed embodiments further illustrate the purpose, technical solution, and beneficial effects of the embodiments of this application. It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application. Any modifications, equivalent substitutions, improvements, etc., made on the basis of the technical solutions of the embodiments of this application should be included within the protection scope of the embodiments of this application.
