DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0034] The utility model provides a storage in-and-out system for vertical warehouses with irregular pallets, so as to solve the problem in the prior art that different pallet standards are different due to different material suppliers, which leads to chaotic placement of materials with pallets and inability to store materials efficiently.

[0035] For ease of understanding, the specific process in the embodiments of the present application is described below. Figures 1 to 4 In the embodiment of the present application, a storage warehouse in and out system suitable for irregular pallets includes a storage warehouse 1, an automatic destacking device 2, an inbound conveyor line 3, an outbound conveyor line 4, an inbound rotary chain machine 5, an outbound rotary chain machine 6, a laser forklift 7, an inbound cache shelf 8 and an outbound cache shelf 9; the storage warehouse 1 is equipped with a four-way vehicle 12 that can transport materials on each shelf in the storage warehouse 1 through an inbound elevator 10, an outbound elevator 11 and multiple inter-layer chain machines, wherein the inbound elevator 10 and the outbound elevator 11 receive or send out the mother pallet in the length direction of the long side, and the mother pallet is used to place materials with non-standard pallets.

[0036] The automatic unpacking device 2 is arranged on one side of the storage warehouse 1, and one end of the inbound conveyor line 3 and the outbound conveyor line 4 are respectively used to connect to the inbound elevator 10 and the outbound elevator 11; the automatic unpacking device 2 is used to send the mother pallet to the inbound conveyor line 3 in the length direction of the long side and receive the mother pallet sent back by the outbound conveyor line 4 in the length direction of the long side; the inbound rotating chain machine 5 and the outbound rotating chain machine 6 are respectively connected to the other end of the inbound conveyor line 3 and the outbound conveyor line 4, so as to rotate the mother pallet sent by the automatic unpacking device 2 at multiple angles. In this embodiment, the mother pallet is mainly rotated 90° to switch the mother pallet in the transmission direction of the long side or the short side.

[0037] The incoming buffer shelf 8 and the outgoing buffer shelf 9 are respectively arranged on one side of the incoming rotary chain machine 5 and the outgoing rotary chain machine 6 to cache incoming materials or outgoing materials; the laser forklift 7 is used to clamp the non-standard pallet carrying materials from the incoming buffer shelf 8 in the length direction of the short side of the non-standard pallet and then transfer it between the incoming buffer shelf 8, the outgoing buffer shelf 9, the incoming rotary chain machine 5 and the outgoing rotary chain machine 6.

[0038] The utility model is suitable for a storage and retrieval system for irregular pallets in vertical warehouses. The storage rotating chain machine 5 aligns the mother pallet sent out by the automatic unstacking device 2 with the non-standard pallet clamped by the laser forklift 7 in the length direction of the short side. The laser forklift 7 places the non-standard pallet and the material on the mother pallet. The storage rotating chain machine 5 then rotates the mother pallet with the material and the non-standard pallet 90°, so that the mother pallet is aligned with the storage conveyor line 3 in the direction of the long side. The storage rotating chain machine 5 then sends the mother pallet to the storage elevator 10 in the length direction of the long side through the storage conveyor line 3 for storage of the material in the vertical warehouse, thereby realizing three-dimensional storage of materials loaded on non-standard pallets.

[0039] Moreover, when the mother pallet with materials and non-standard pallets on the outbound rotating chain machine 6 aligns the short side of the non-standard pallet with the laser forklift 7, the laser forklift 7 forks the short side of the non-standard pallet and then forks the materials carrying the non-standard pallet from the mother pallet and sends them to the outbound cache shelf.

[0040] Based on this, the storage and retrieval system for the warehouse vertical warehouse can place materials on non-standard pallets on the mother pallet and then store them in the warehouse vertical warehouse. The whole process is completed automatically, with high efficiency in warehousing and outbound operations, meeting actual usage needs.

[0041] In this embodiment, the incoming cache shelf 8 and the outgoing cache shelf 9 are provided with photoelectric sensors for identifying materials. When the photoelectric sensors identify the presence of materials, the control system can notify the laser forklift 7 to fork away the relevant materials on the incoming cache shelf 8 and the outgoing cache shelf 9.

[0042] based on Figure 5 In this embodiment, the automatic unstacking equipment 2 is provided with a discharging transmission line 20 for sending out the mother pallet, and the discharging transmission line 20 is vertically connected to the middle position of the roller conveyor 21, and the two ends of the roller conveyor 21 are respectively vertically connected to the inbound conveyor line 3 and the outbound conveyor line 4; the roller conveyor 20 is provided with a lifting and steering mechanism 22 for lifting and rotating the mother pallet at the docking position with the discharging transmission line 20, the inbound conveyor line 3 and the outbound conveyor line 4.

[0043] The automatic unstacking device 2 is responsible for automatic pallet stacking and automatic unstacking tasks. When it is outbound, it will automatically pass through the corresponding conveyor line when it is fully stacked, and will be placed in the storage warehouse 1 by the four-way vehicle 12; when it is inbound, the mother pallet will be unpacked and sent to the inbound conveyor line 3. When there is no mother pallet inside the automatic unstacking device 2, the four-way vehicle 12 will automatically send a mother pallet from the storage warehouse 1.

[0044] When the automatic unstacking equipment 2 sends the mother pallet out to the roller conveyor 21 in the length direction through the discharge transmission line 20, the lifting and steering mechanism 22 lifts the mother pallet and rotates it 90°, so that the mother pallet is transported in the length direction of the roller conveyor 21 in the direction of the short side. When the mother pallet moves to the joint of the roller conveyor 21 and the storage conveyor line 3, the lifting and rotating mechanism 22 at the storage conveyor line 3 rotates the mother pallet in the opposite direction by 90°, so that the mother pallet can be transported to the storage conveyor line 3 in the length direction of the long side.

[0045] For the outbound conveyor line 4, the outbound conveyor line 4 is used to transfer the mother pallet sent out in the long side direction back to the docking point between the outbound conveyor line 4 and the roller conveyor 21 on the left side. The lifting and rotating mechanism 22 at the docking point between the outbound conveyor line 4 and the roller conveyor 21 transfers the mother pallet sent out in the long side direction into the roller conveyor 21 in the short side direction, and then the mother pallet transferred in the short side direction is rotated 90° through the lifting and rotating mechanism 22 at the docking point between the outbound conveyor line 20 and the roller conveyor 21, and then transferred and recovered in the long side direction to the automatic folding device 2.

[0046] based on Figures 6 to 9 In this embodiment, the structures of the storage rotating chain machine 5 and the outbound rotating chain machine 6 are the same. The storage rotating chain machine 5 is described in detail here. The storage rotating chain machine 5 includes a base 50. The upper surface of the base 50 is provided with a rotating table 52 which can be rotated by a meshing gear assembly 51, and the gear assembly is driven to rotate by a motor 53; the rotating table 52 is provided with a group of transmission chains 56 driven by a chain motor 54 and a transmission rod 55 for docking and transmitting the mother pallet.

[0047] During operation, the chain motor 54 and the transmission rod 55 drive the transmission chain 56 to transport the mother pallet sent from the inbound conveyor line 3 and the outbound conveyor line 4 back and forth; at the same time, when the turntable 52 needs to be rotated 90°, the motor works, and the motor 53 drives the gear assembly 51 to rotate, and the gear assembly is connected to the turntable 52, thereby driving the turntable 52 to rotate accordingly.

[0048] In addition, the four bottom corners of the inbound rotary chain machine 5 and the outbound rotary chain machine 6 are respectively provided with weighing mechanisms 57 for sensing the weight of materials, so that the weight of materials in the mother pallet can be identified, making it convenient for unqualified and overweight materials to be sent out by the laser forklift 7 after being NG.

[0049] based on Figure 5 In this embodiment, a REC scanning mechanism 61 is provided on one side of the inbound conveyor line 3 and the outbound conveyor line 4, respectively, for scanning the barcode on the mother pallet, so as to count the inbound and outbound materials for subsequent totaling.

[0050] In addition, in this embodiment, the inbound conveyor line 3 and the outbound conveyor line 4 are respectively provided with an appearance detection mechanism 62 at the joints with the inbound rotary chain machine 5 and the outbound rotary chain machine 6 for judging the appearance of the material. Here, the material on the inbound rotary chain machine and the outbound rotary chain machine is directly identified. When it is found that the specifications of the material do not meet the requirements, the control system directly notifies the laser forklift to return the material.

[0051] based on Figure 2 In this embodiment, a plurality of reflective columns 60 for the laser forklift 7 to identify the position are provided around the inbound cache shelf 8 and the outbound cache shelf 9 and at the inbound rotating chain machine 5 and the outbound rotating chain machine 6. Since the laser forklift 7 requires light for identification, a plurality of reflective columns are added to enhance the identification function of the laser forklift to ensure the accuracy of the position of the laser forklift 7 when working.

[0052] The actual workflow is as follows:

[0053] When non-standard pallet materials need to be put into storage:

[0054] Sa1. WMS issues a warehouse entry list, and the non-standard pallet with materials is manually placed in the material grid of the warehouse entry cache shelf 8. At this time, the barcode needs to be manually posted on the pallet and the relevant material information is bound with the PDA system;

[0055] Sa2: When there are materials in the material grid of the incoming buffer shelf 8, the photoelectric sensor will automatically determine whether there is material or not after sensing it. When there is a non-standard pallet with materials in the incoming buffer shelf 8 and there is no one, the laser forklift 7 will automatically connect to the non-standard pallet with materials. At this time, the system will send a mother pallet to the incoming conveyor line 3 in advance by the automatic folding device 2, and then the incoming conveyor line 3 will send it to the incoming rotary chain machine 5. The mother pallet just sent to the incoming rotary chain machine 5 has its long side facing the short side of the non-standard pallet connected to the laser forklift 7. Therefore, the incoming rotary chain machine 5 will rotate the mother pallet 90° at this time to align the short side of the mother pallet with the short side of the non-standard pallet.

[0056] Sa3. At this time, the laser forklift 7 will automatically place the materials in the non-standard pallet on the mother pallet according to the instructions issued by the WCS, and then retreat to a safe position to inform the PLC system. After the placement is completed, the PLC system executes the warehousing action; among them, for the sake of greater safety, we have added an inquiry function. In front of the placement position of the laser forklift 7, we have added a safe position for safety inquiry to ask the PLC system whether it can be placed. The PLC informs the mother pallet in place, and at the same time, the warehousing rotating chain machine 5 will rotate into place, that is, the short side of the rotated mother pallet is aligned with the short side of the non-standard pallet. At this time, the material can be placed, and the laser forklift will place the non-standard pallet material on the mother pallet in the center to ensure that the non-standard pallet is completely within the space range of the mother pallet;

[0057] Sa4. The four weighing mechanisms 57 at the bottom of the warehouse rotating chain machine 5 determine the weight of the material. If it is unqualified, it will be taken out by the laser forklift 7 and sent out; if it is qualified, the warehouse rotating chain machine 5 will rotate so that the long side of the mother pallet carrying the material is aligned with the warehouse conveyor 3, and then the shape detection mechanism 62 at the front end of the warehouse conveyor 3 will pass the shape detection and report it to the WMS system after scanning the code. The WMS allocates the cargo location, and the WCS system performs scheduling and execution. Then the mother pallet will be connected to the corresponding cargo location through the warehouse conveyor 3, the warehouse elevator 10, the interlayer chain machine and the four-way vehicle 12 in turn and then reported as completed.

[0058] When the mother pallet materials need to be shipped out:

[0059] Sb1. After WMS issues a warehouse order, the mother pallet carrying the non-standard pallet and materials passes through the four-way vehicle 12, the inter-layer chain machine, the warehouse elevator, the warehouse conveyor line 4 to the warehouse rotary chain machine 6 in sequence. After it is in place, the laser forklift 7 is notified to pick up the goods. Here, the arrival refers to the short side of the non-standard pallet aligning with the laser forklift 7 in place. After the laser forklift 7 aligns with the short side of the non-standard pallet, it places the materials and the non-standard pallet on the warehouse cache shelf 9 for shipment or sorting;

[0060] Sb2. After the laser forklift 7 picks up the non-standard pallet and materials and reaches a safe distance, it notifies the outbound rotating chain machine 6 that the picking up is completed. The outbound rotating chain machine 6 automatically rotates the mother pallet 90° and aligns the long side of the mother pallet with the outbound conveyor line 4. The outbound conveyor line 4 sends the mother pallet to the automatic destacking device 2 through the jacking and rotating mechanism 22, thereby completing the entire outbound and inbound process of the non-standard pallet carrying materials.

[0061] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
