DETAILED DESCRIPTION

[0038] Embodiment 1:

[0039] This embodiment provides a stacking type material box storage system, such as Figure 1 As shown, it includes a material box storage area 100, a material box picking and placing device 200, a material box buffer area 700, a top conveying device 800, a lifting device 900 and a bottom transfer device 1000. The material box buffer area 700 is arranged above the material box storage area 100. Compared with other temporary storage methods, it can save ground space.

[0040] Specifically, a plurality of material box storage areas 100 are arranged at intervals, each material box storage area 100 is used to store material boxes 101, and the number of material box storage areas 100 is determined according to the stacking amount of material boxes 101. Material box 101 is a material box, which stores single or multiple specifications of materials.

[0041] Figure 1 Two material box storage areas 100 are shown. The material box picking and placing device 200 picks the material boxes to be shipped out from one of the material box storage areas 100 and temporarily stores them in the material box buffer area 700; the other material box storage area 100 is used to stack the material boxes to be shipped in after being shipped out and picked.

[0042] In this embodiment, the material boxes are stacked directly on the ground, and the stacking height of the material boxes depends on the number of material boxes.

[0043] A support 102 is provided above the material box storage area 100, and a material box buffer area 700 is formed above the support 102, that is, the upper space of the support 102 is used to stack the selected material boxes to be shipped out, or to stack the material boxes to be shipped in. By providing the support 102, the material box storage area 100 and the material box buffer area 700 only occupy the longitudinal space, saving the floor space during the material box picking process.

[0044] like Figure 1 As shown, the material box picking and placing device 200 has a mobile performance, which can move to the side of the material box storage area 100, pick out the material boxes to be shipped out, and lift the material boxes to be shipped out to the material box buffer area 700. Considering the picking efficiency of the material boxes to be shipped out, the material box picking and placing device 200 itself can also be set with a buffer position to meet the needs of different order quantities.

[0045] The material box picking and placing device 200 adopts a fork-picking method for the material box, so the material box picking and placing device 200 includes a fork 203; similarly, in order to meet the requirements of different order quantities, the material box picking and placing device 200 can be provided with a single set of forks 203 or multiple sets of forks 203. Figure 3 A material box picking and placing device 200 with a single set of forks 203 is shown. The material box picking and placing device 200 also includes a support frame 201, and the forks 203 are installed on the inner side of the support frame 201; because picking and placing the material box requires a clamping action, the forks 203 are arranged in pairs, that is, a set of forks 203 includes two opposing fork arms.

[0046] A buffer position is provided on at least one side of the support frame 201, and the fork 203 places the taken material box to be shipped to the buffer position or the material box buffer area 700. Therefore, the fork 203 has lifting and rotating actions. In this embodiment, the fork 203 is installed on a base, the base is connected to a rotating mechanism, and the rotating mechanism is connected to a lifting mechanism 205, so as to meet the lifting and rotating requirements of the fork 203.

[0047] It should be noted that the rotating mechanism and the lifting mechanism 205 are both implemented using existing technologies. For example, the lifting mechanism 205 uses a chain transmission mechanism, a belt transmission mechanism or other mechanisms driven by a motor; the rotating mechanism includes a rotating seat rotatably connected to the base, and the rotating seat is connected to a rotating motor, etc.

[0048] This embodiment is described in detail by taking the example of setting cache positions on both sides of the support frame 201: Figure 3 As shown, the cache position is formed by support plates 204 arranged at intervals along the height direction of the support frame 201, and there is a certain spacing between adjacent support plates 204, which can be equal or unequal; the space above the upper surface of the support plate 204 is the cache position. The cache position can be used to place a single layer of material boxes, or can be stacked with multiple layers of material boxes; the cache positions on both sides of the support frame 201 can store the same or different numbers of material boxes, thereby forming a variety of material box cache forms.

[0049] Figure 4 A material box picking and placing device 200 with two sets of forks 203 is shown. The difference between the two sets of forks 203 and the single set of forks 203 is that the upper forks 203 may have only a lifting function or may have both a lifting and rotating function.

[0050] In this embodiment, the boxes to be shipped out are stacked in multiple rows and columns on the upper side of the support 102 after being picked up by the box picking and placing device 200. In order to transfer the boxes to be shipped out, a top conveying device 800, a lifting device 900 cooperating with the top conveying device 800, and a bottom transfer device 1000 are also provided on the support 102. Figure 1 As shown, the lifting device 900 is arranged on one side of the material box storage area 100 and the material box buffer area 700, and the bottom transfer device 1000 is arranged on the ground.

Figure 5 As shown, the top conveying device 800 includes a first mobile chassis 801 and a picking mechanism 802. The picking mechanism 802 is installed above the first mobile chassis 801. The first mobile chassis 801 is set to enable the top conveying device 800 to move between the stacked boxes to be shipped out; the picking mechanism 802 uses a fork 203 to realize the clamping function.

[0052] like Figure 6 and Figure 8As shown, the lifting device 900 has the function of transporting the material boxes to be shipped out of the top conveying device 800 to the bottom transfer device 1000; and also has the function of transporting the material boxes to be shipped in the bottom transfer device 1000 to the top conveying device 800. The lifting device 900 includes a first cargo platform 901 and a lifting drive mechanism 902. The first cargo platform 901 is connected to the lifting drive mechanism 902. Under the action of the lifting drive mechanism 902, it can dock with the top conveying device 800 and the bottom transfer device 1000 to achieve the transfer of the material box position.

[0053] The lifting drive mechanism 902 is implemented by existing technology, such as a chain transmission mechanism or a belt transmission mechanism driven by a motor. In this embodiment, the first cargo platform 901 includes a support frame connected to the lifting drive mechanism 902, and a plurality of transmission rollers installed on the support frame, and the transfer of the material box is achieved through the rotation of the transmission rollers.

[0054] The bottom transfer device 1000 has the function of receiving the material boxes to be shipped out from the lifting device 900 and transporting them to the picking and shipping device 300; it also has the function of receiving the material boxes to be shipped in from the automatic material box storage device 400 and transporting them to the lifting device 900. Figure 7 As shown, the bottom transfer device 1000 includes a second mobile chassis 1001 and a second cargo platform 1002 installed on the top of the second mobile chassis 1001. The second cargo platform 1002 also has a plurality of transmission rollers to meet the requirements of material box transfer.

[0055] In this embodiment, the first mobile chassis 801, the second mobile chassis 1001 and the third mobile chassis 202 can be realized by an AGV vehicle; of course, in other embodiments, each mobile chassis can also adopt other moving mechanisms.

[0056] In this embodiment, a material box buffer area 700 is set above the material box storage area 100, that is, the cache material box is located at the top of the stacked material boxes, does not occupy additional space, and the material box buffer capacity is large; through the cooperation of the material box picking and placing device 200, the top conveying device 800, the lifting device 900 and the bottom transfer device 1000, the transfer of material boxes to be stored and the material boxes to be shipped out are realized, the processes are processed step by step, and each process is processed by the corresponding device, which is more efficient.

[0057] Embodiment 2:

[0058] This embodiment provides a stacking type material box storage system, such as Figure 2 As shown, the difference from the first embodiment is that the end of the bracket 102 close to the lifting device 900 is connected through the connecting channel 103, the top conveying device 800 can move on the bracket 102 and the top of the connecting channel 103, and the lifting device 900 is arranged on one side of the connecting channel 103.

[0060] Depending on the size and processing capacity of the material box stack, one or more top conveying devices 800 can be set.

[0061] The remaining structures are the same as those in the first embodiment and will not be described again here.

[0067] The warehouse management device 600 has the functions of receiving orders, analyzing orders, issuing picking tasks, managing material box storage locations, etc., which are implemented through a computer system and are existing technologies and will not be described in detail here.

[0068] The workflow of this embodiment is:

[0069] 1. Material box outbound process:

[0070] A. The material box picking and placing device 200 enters the material box stacking storage device 100, takes out the material box to be shipped out from the corresponding position according to the instructions issued by the warehouse management module 600, and stacks and caches it on the material box picking and placing device 200.

[0071] B. The material box picking and placing device 200 runs to the material box buffer area 700, places the material boxes to be shipped out of the warehouse on the material box buffer area 700, and automatically plans the unloading position and the number of stacking layers according to the number of material boxes and the free buffer positions in the material box buffer area 700.

[0072] C. The top conveying device 800 automatically runs to the corresponding cache position of the material box to be shipped out in the material box buffer area 700. The fork of the picking mechanism of the top conveying device 800 clamps the single or stacked material box to be shipped out, and then the fork retracts, and the single or stacked material box to be shipped out is automatically transported to the docking position at the lifting device 900.

[0073] For the case where a connecting passage 103 is provided between the material box storage areas 100, as shown in FIG. Figure 2 As shown, the top conveying device 800 can shuttle between the outbound cache position and the inbound cache position on the top of each stack through the connecting channel 103, and can transport the material boxes to be outbound to the lifting device 900; it can also lift the lifting device 900 to the top of the material boxes to be inbound and transport them to the inbound cache position.

[0074] D. After the lifting device 900 receives the material box to be shipped delivered by the top conveying device 800, the first cargo platform 901 begins to descend, and lowers the material box to the docking position of the bottom transfer device 1000, and then the lifting device 900 transports the material box to the bottom transfer device 1000. The bottom transfer device 1000 transports the material box to be shipped to the position of the picking and shipping device 300.

[0075] E. The picking and hauling device 300 automatically docks with the bottom transfer device 1000, and disassembles the single or stacked material boxes to be dispatched from the bottom transfer device 1000, and dissembles the stacked material boxes into single material boxes, and finally transports them to the material picking device 500 through the first conveying mechanism 302; if the material to be dispatched is a single material box, it is directly transported to the material picking device 500.

[0076] F. The material picking device 500 picks out the required items according to the order prompt information and puts them into the order material box, and the order material box is shipped out of the warehouse through the conveyor line; after the sorting is completed, the material box is transported to the material box automatic warehousing device 400 through the conveyor line and waits for warehousing.

[0077] 2. Process of returning outbound material boxes to the warehouse:

[0078] A. The material box stacking mechanism 401 in the material box automatic storage device 400 stacks single material boxes into stacked material boxes; the stacked material boxes are conveyed and lifted to corresponding height positions.

[0079] B. The automatic material box storage device 400 and the bottom transfer device 1000 are automatically docked, and the bottom transfer device 1000 receives a single or stacked material box to be stored. The bottom transfer device 1000 transports the material box to be stored to the lifting device 900, and the lifting device 900 automatically docks with the bottom transfer device 1000, and the material box to be stored is transported to the first cargo platform 901 on the lifting device 900 through the transmission roller on the top of the bottom transfer device 1000.

[0080] C. The lifting device 900 lifts the material box to be stored to the top of the support and reaches the docking position with the top conveying device 800. The top conveying device 800 reaches the docking position with the lifting device 900 according to the instruction of the warehouse management module 600, and the fork of the picking mechanism 802 extends to clamp the material box to be stored and then retracts it, and moves the material box to be stored to the top conveying device 800, and then the top conveying device 800 runs to the material box buffer area 700, and temporarily stores the single or stacked material boxes to be stored in the buffer position of the material box buffer area 700.

[0081] During this process, the warehouse management module 600 will autonomously plan the optimal buffer position and control the top conveying device 800 to reach the corresponding position. At this point, the material box to be stored has arrived at the buffer position at the material box buffer area 700, and then waits for the material box pick-up and placement device 200 to transport the material box to be stored to the final target storage position.

[0082] D. The material box picking and placing device 200, according to the instructions of the warehouse management module 600, clamps the material boxes to be stored in the material box buffer area 700, and places the material boxes on the support plate 204 of the material box picking and placing device 200 through lifting, rotating and other actions. After the material box picking and placing device 200 carries the material boxes to be stored to the target storage position of the material box stacking storage device 100, it takes the material boxes out of the vehicle body and restacks them to the corresponding position of the material box stacking storage device 100; the system can optimize the storage position of the material boxes at any time according to order requirements.

[0083] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
