[0025] In order to solve the problems in the prior art, the present invention proposes a solution to change the traditional planar storage to the three-dimensional storage: the boxes that need to be stored are transported to the stacker for stacking, and the photoelectric switch is used for stacking. The machine performs detection. When it detects that the boxes are stacked, the programmable logic controller (PLC) controls the conveyor line to transport the stacked boxes to the storage library for storage; When the box body is obtained in the warehouse, the box body in the storage library is transported to the destacker; the photoelectric switch is used to detect the destacker. When the box is detected to reach the destacker, the destacker will disassemble the box. After stacking, the PLC-controlled conveyor line transports the boxes after destacking, which reduces the floor space occupied by the warehouse when the boxes are stored, reduces storage costs, and improves work efficiency.
[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments.

Such as figure 2 As shown, the system includes a roller conveyor 1, a conveyor line 2 and a stacker 3, one end of the stacker 3 is connected to the conveyor 1, and the other end of the stacker 3 is connected to the conveyor line 2. The boxes that need to be stored are transported to the stacker 3 through the roller conveyor 1, and the stacker 3 stacks the boxes that are sequentially transported in, and the completed boxes are transported to the conveyor line 2 , The conveying line 2 will transport the stacked boxes to the designated storage warehouse.
[0028] It should be noted that the number of boxes to be stacked in the stacker is determined according to actual needs, so that the required stacker can be designed according to the actual situation.
[0029] According to the difference in the internal structure of the stacker, the three-dimensional storage of the box can be divided into two different embodiments: the top-down three-dimensional storage and the bottom-up three-dimensional storage. The two embodiments are respectively described below. Description.
[0030] image 3 It is a schematic structural diagram of an embodiment of the present invention for realizing three-dimensional storage from top to bottom. Such as image 3 As shown, in addition to the roller conveyor 1, the conveyor line 2, and the stacker 3, the system of the three-dimensional storage embodiment also includes a climbing belt conveyor 4, wherein the stacker 3 includes a stacker The cylinder 5, the stacker carriage 6 and the lifting mechanism 7, the roller conveyor 1 is connected to one end of the climbing belt conveyor 4, and the other end of the climbing belt conveyor 4 is installed under the stacker cylinder 5 to make the stacking The cylinder 5 of the stacker moves back and forth in the horizontal direction, and the carriage 6 of the stacker moves up and down in the vertical direction under the action of the lifting mechanism 7. The lifting mechanism 7 further includes a sprocket 8, a chain 9 and a guide rail 10. The stacker carriage 6 is driven by the sprocket 8, the chain 9 and the guide rail 10 to move up and down in the vertical direction. Further, the system may include a photoelectric switch 11 and a PLC 12. The vertical movement of the stacker carriage 6 is controlled by the photoelectric switch 11, and the photoelectric switch 11 controls the stacker carriage 6 Again, the PLC 12 controls the photoelectric switch 11 to complete.
[0031] When the box needs to be stored, first transport the box to be stored to the roller conveyor 1. The box is transported by the roller conveyor 1 to the climbing belt conveyor 4 connected to it, and the box is on the climbing belt The machine 4 is transported to the entrance of the stacker 3 by the lifting action. Furthermore, the stacker cylinder 5 at the entrance pushes the box onto the stacker carriage 6, and the photoelectric switch 11 pairs the stacker carriage 6 Perform regular inspections. When it is detected that the box reaches the stacker carriage 6, the PLC 12 controls the rotation of the sprocket 8 in the lifting mechanism 7 so that the chain 9 wound on the sprocket 8 moves along the guide rail 10. , Complete the operation of lowering the stacker carriage 6 by the height of the box; when the photoelectric switch 11 detects that the box has not reached the stacker carriage 6, it will continue to check the stacker carriage 6 regularly , Until the box body reaches the stacker pallet 6, and then controlled by the PLC 12 to lower the stacker pallet 6 by the height of the box.
[0032] Repeat the above-mentioned operations of conveying, pushing in, detecting, and lowering the boxes that need to be stored until the stacker carriage 6 cannot be lowered, and a stacking of the boxes is completed. At this time, the stacking The stacked boxes are transported to the conveyor line 2 under the control of the PLC 12. The boxes are stored in the designated storage library under the conveying action of the conveyor line 2. At this time, the three-dimensional storage system can transport it in again The box body for the next stacking operation.
[0033] It should be noted that in this embodiment, the photoelectric switch 11 and PLC 12 are not image 3 They are marked in, because their positions are uncertain. They can be installed at any position inside the stacker 3 or outside the stacker 3, as long as the stacker carriage 6 can be controlled separately. The detection and control of the photoelectric switch 11 to the stacker carriage 6 is sufficient, and does not affect the implementation of the embodiment of the present invention.
[0034] Figure 4 It is a schematic structural diagram of an embodiment of the present invention for realizing three-dimensional storage from bottom to top. Such as Figure 4 As shown, the three-dimensional storage embodiment includes a roller conveyor 1, a conveyor line 2, and a stacker 3. The stacker 3 specifically includes a stacker carriage 6 and a jacking cylinder 13. The stacker The carriage 6 moves up and down in the vertical direction under the action of the jacking cylinder 13. Similarly, in this embodiment, a photoelectric switch 11 and a PLC 12 are included. The vertical movement of the stacker carriage 6 is controlled by the photoelectric switch 11, and the photoelectric switch 11 is opposite to the stacker carriage. The control of 6 is completed by the PLC12 controlling the photoelectric switch 11.
[0035]In this embodiment, when the box needs to be stored, the box is directly transported to the stacker 3 through the roller conveyor 1, and the jacking cylinder 13 at the bottom of the stacker 3 will be transported under the control of the PLC 12. The incoming box is lifted onto the stacker pallet 6, and the photoelectric switch 11 regularly detects the stacker pallet 6. When it is detected that the box reaches the stacker pallet 6, the PLC 12 controls the jacking The air cylinder 13 raises the stacker carriage 6 by the height of the box. When it is detected that the box does not reach the stacker carriage 6, the photoelectric switch 11 will continue to perform timing detection on the stacker carriage 6 until it is detected. After the box body reaches the stacker carriage 6, the PLC 12 controls the lifting cylinder 13 to raise the stacker carriage 6 by the height of the box body. After the box body is lifted, perform the pairing. Do the same for the next input box.
[0036] Repeat the above-mentioned conveying, lifting, detecting and lifting operations until the PLC 12 cannot control the lifting of the stacker carriage 6 to complete a stack. After the stacking is completed, a whole stack of boxes is in the PLC Under the control of 12, it is transported to the conveying line 2, and then the stacked boxes are transported to the designated storage warehouse by the conveying line 2.
[0037] Like the top-down three-dimensional storage embodiment, in this embodiment, the photoelectric switch 11 and the PLC 12 are not Figure 4 They are marked in, because their positions are uncertain. They can be installed at any position inside the stacker 3 or outside of the stacker 3, as long as the stacker carriage 6 can be controlled separately. The detection and control of the photoelectric switch 11 is sufficient for the detection of the stacker carriage 6 and does not affect the implementation of the embodiment of the present invention.
[0038] Through the operations of the above two embodiments, the three-dimensional storage of the boxes is completed. If the boxes need to be obtained from the three-dimensional storage storage library, the three-dimensional sorting operation of the stacked boxes in the storage library is required. , Figure 5 It is a schematic structural diagram of an embodiment of the present invention for realizing three-dimensional sorting. Such as Figure 5 As shown, the system includes a roller conveyor 1, a conveyor line 2 and a destacker 3. One end of the destacker 3 is connected to the roller conveyor 1, and the other end of the destacker 3 is connected to the conveyor line 2. When it is necessary to sort the boxes after the three-dimensional storage in the storage warehouse, the boxes that need to be sorted are transported to the destacker 3 through the roller conveyor 1, and the destacker 3 pairs in the boxes. The boxes are destacked, and the boxes after the destacking are transported to the conveyor line 2, and finally the boxes after the destacking are transported out by the conveyor line 2, so as to complete the operation of sorting the boxes.
[0039] It should be noted that the number of boxes that can be unstacked in the destacker is arbitrary, and the appropriate destacker can be selected according to the number of a whole stack of boxes in the storage warehouse.
[0040] As with the stacking of boxes, the stacking of boxes in the storage warehouse can be divided into three-dimensional sorting from top to bottom and three-dimensional sorting from bottom to top according to the internal structure of the destacker. There are two kinds of sorting, and the two different sorting embodiments will be described below.
[0041] Figure 6 It is a schematic structural diagram of an embodiment of the present invention for realizing three-dimensional sorting from top to bottom. Such as Figure 6 As shown, the system of the three-dimensional sorting embodiment includes a roller conveyor 1, a conveyor line 2, and a destacker 3. The destacker 3 specifically includes a destacker carriage 4, a lifting mechanism 5, and a destacker. The stacker cylinder 6, the destacker carriage 4 moves up and down in the vertical direction under the action of the lifting mechanism 5. The destacker cylinder 6 is located on the side opposite to the conveyor line 2 at the top, and the lifting mechanism 5 again It includes a sprocket 7, a chain 8 and a guide rail 9. The destacker carriage 4 is driven by the sprocket 7, the chain 8 and the guide rail 9 to move up and down in the vertical direction. Further, the system also includes a photoelectric switch 10 and a PLC 11. The vertical up and down movement of the destacker carriage 4 is controlled by the photoelectric switch 10, and the photoelectric switch 10 controls the destacker carriage 4 again. The PLC 11 controls the photoelectric switch 10 to complete.
[0042] When sorting the stacked boxes in the storage warehouse, the boxes are first transported to the destacker 3 through the roller conveyor 1, and the photoelectric switch 10 performs timing detection on the destacker 3. When it is detected After the box body reaches the destacker 3, the uppermost box body is controlled by the PLC 11 to transport the pallet 4 of the destacker, and then the sprocket 7 in the lifting mechanism 5 is controlled by the PLC 11 to rotate, thereby driving the winding on the sprocket The chain 8 on 7 moves along the guide rail 9, so that the destacker carriage 4 rises by the height of the box body. At this time, the destacker cylinder 6 located on the upper part of the destacker pushes a rising box out of the destacker 3 , The box body is further pushed onto the conveying line 2 and then transported out; when the photoelectric switch 10 detects that the box body has not reached the destacker 3, it will continue to perform timing detection on the destacker 3 until the box body reaches the destacker 3. After the stacker 3, the PLC 11 controls the operation of raising the depalletizer carriage 4 by one box height.
[0043] Repeat the above-mentioned operations of detecting, lifting, pushing out and conveying the boxes that need to be sorted until all the boxes are transported out. At this time, the three-dimensional sorting system can input the latter into the destacker 3. The same operation is performed on the box.
[0044] It should be noted that in this embodiment, the photoelectric switch 10 and the PLC 11 are not Figure 6 They are marked in, because their positions are uncertain. They can be installed at any position inside the destacker 3 or outside of the destacker 3, as long as they can be separately controlled for the destacker carriage 4 The detection and control of the photoelectric switch 10 is sufficient for the detection of the carriage 4 of the destacker, which does not affect the implementation of the embodiment of the present invention.
[0045] Figure 7 It is a schematic structural diagram of an embodiment of the present invention for realizing three-dimensional sorting from bottom to top. Such as Figure 7 As shown, the bottom-up three-dimensional sorting embodiment includes a roller conveyor 1, a conveyor line 2, and a destacker 3. The destacker 3 specifically includes a destacker carriage 4 and a jacking cylinder 12 , The carriage 4 of the destacker moves up and down in the vertical direction under the action of the jacking cylinder 12. This embodiment also includes a photoelectric switch 10 and a PLC 11. The vertical movement of the depalletizer carriage 4 is controlled by the photoelectric switch 10, and the photoelectric switch 10 controls the depalletizer carriage 4 again. The control of the photoelectric switch 10 by the PLC 11 is completed.
[0046] In this embodiment, when the stacked boxes in the storage warehouse need to be sorted, the boxes are first transported to the destacker 3 through the roller conveyor 1, and the photoelectric switch 10 is used to regularly disassemble the boxes. The stacker 3 performs detection. When it is detected that the box reaches the destacker 3, under the control of the PLC 11, all the boxes except the bottom box are transported to the pallet 4 of the destacker, and then the PLC 11 The lifting cylinder 12 is controlled to lift the tray 4 of the destacker. At this time, a box that has not been lifted is controlled by the PLC 11 to control the conveyor line 2 to output it to the destacker; when the photoelectric switch 10 detects that the box is returned When the destacker 3 is not reached, the destacker 3 will continue to be inspected regularly until the box is detected to reach the destacker 3, and then the PLC 11 control is completed to make the destacker carriage 4 rise, and then control the conveying line 2 The operation of transporting out the box that has not been jacked.
[0047] Repeat the above-mentioned operations of detecting, lifting and conveying the boxes that need to be sorted until all the boxes are transported out. At this time, the three-dimensional sorting system can input the latter box into the destacker 3. The body performs the same operation.
[0048] Same as the top-down three-dimensional sorting embodiment, in this embodiment, the photoelectric switch 10 and the PLC 11 are not in the Figure 6 They are marked in, because their positions are uncertain. They can be installed at any position inside the destacker 3 or outside of the destacker 3, as long as they can be separately controlled for the destacker carriage 4 The detection and control of the photoelectric switch 10 is sufficient for the detection of the carriage 4 of the destacker, which does not affect the implementation of the embodiment of the present invention.
[0049] So far, the process of the three-dimensional storage and three-dimensional sorting of the boxes of the present invention is completed.
[0050] In a word, the present invention uses a stacker to perform three-dimensional storage of boxes that need to be stored: the boxes that need to be stored are first transported to the stacker, and the boxes are stacked in the stacker and then on the conveyor line. It is transported to the storage warehouse under the transmission action of the storage; accordingly, the stacked boxes in the storage warehouse are sorted three-dimensionally by a destacker: the stacked boxes that need to be sorted are sorted first. It is transported to the destacker, and the boxes after being destacked in the destacker are transported to the conveyor line and then transported out of the storage warehouse under the transmission action of the transport. By applying the three-dimensional storage and sorting system and method of the present invention, the storage and sorting of boxes can be completed, while the area occupied during storage is reduced, the storage cost is reduced, and the work efficiency is improved.
[0051] In summary, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
