Description

Technical Field

[0001] The present invention belongs to the field of material transportation regularization, and particularly relates to a stacking material conveying method linked with a warehousing system. Background Art

[0002] In a furniture raw material processing production line, an automated stereoscopic warehouse stores materials on shelves in a three-dimensional manner. However, since there are multiple raw materials used in furniture production in the automated stereoscopic warehouse, it is very difficult for the PLC system to record information of numerous materials and make flexible countermeasures for feeding, returning, and in-out of the production line and the warehouse. Moreover, the processes of feeding, returning, warehousing, and out-of-warehouse are mostly transported by manually operating machines. Due to the intervention of humans, the error rate is relatively high compared with system control, and the efficiency is not high enough.

[0003] Therefore, it is necessary to design a stacking material conveying method linked with a warehousing system to solve the above problems, which greatly reduces human intervention and improves the working efficiency of the warehouse and the production line.

[0004] Therefore, it is necessary to invent a control method for sheet material regularization to solve the problem of offset and tilt of sheet materials caused by multiple handling. Compared with traditional warehouses, it greatly reduces human intervention and improves the working efficiency of the warehouse.

[0005] For example, a Chinese patent document discloses an intelligent sheet material warehouse sheet material distribution system and its distribution method [Patent Application No.: CN201910859919.9], including a distribution area, the distribution area includes multiple conveying lines arranged horizontally along the direction of the storage location, a recovery conveying line is arranged on one side of the recovery storage location, a gripper robot for grasping sheet materials is arranged between the distribution area and the telescopic recovery conveying line, a distribution conveyor for selecting and conveying to different conveying lines in the distribution area is arranged on one side of the distribution area, the distribution area includes a pick-and-place conveying line corresponding to the distribution storage location for receiving materials and a transfer conveying line connected to the recovery conveying line, and a temporary storage conveying line for placing sheet materials is arranged between the pick-and-place conveying line and the transfer conveying line. Summary of the Invention

[0006] The purpose of the present invention is to provide a stacking material conveying method linked with a warehousing system for the above problems.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A stacking material conveying method linked with a warehousing system, step 1: The management system monitors in real time. When it detects that there are materials in the warehouse, it mobilizes the stacker to stack the materials;

[0009] Step 2: The stacker sorts and stacks the materials, and transports the stacked materials to the hydraulic station through the outbound hydraulic station conveyor line. During this process, the stacker, the outbound hydraulic station conveyor line, and the hydraulic station interact and feedback the outbound information to the management system in real time through the TCP network;

[0010] Step 3: The management system receives the feedback from the hydraulic station that the material stacking information has been received, issues the task of the material stacking outbound hydraulic station through the management system, and identifies the destination of the material stacking information through the management system, manual identification, or wireless scanner;

[0011] Step 4.1: If the outbound task is issued after Step 3 is completed, it is transported to the transfer conveyor line along Route 2 and taken out to complete the outbound. The transfer conveyor line interacts with the management system in real time through the TCP network;

[0012] Step 4.2: If the task issued after Step 3 is completed is to be sent to production, a delivery request is sent to the RGV transfer vehicle, and it is transported to the turntable along Route 2. After receiving the signal, the RGV transfer vehicle moves to the turntable to dock with the turntable and receive the material stack.

[0013] In the above method for conveying stacked materials in linkage with a warehousing system, the transfer conveyor line 14 is used for both the outbound path and the inbound path. When the transfer conveyor line detects that there are materials placed, the materials are identified through the management system, manual identification, or wireless scanner. If the identification information is an outbound task, then Step 4.1 is continued. If the identification information is an inbound message, then Step 5 is carried out;

[0014] Step 5: The management system issues an inbound task and conducts an external shape inspection on the materials. If the external shape inspection is unqualified, the material is removed and the inbound task fails; if the external shape inspection is qualified, then the inbound step is carried out.

[0015] In the above method for conveying stacked materials in linkage with a warehousing system, Step 6: After Step 5 is completed and the external shape inspection is qualified, the No. 1 rotary conveyor line is started, and the materials are sequentially transported to the inbound hydraulic station through the transfer conveyor line, the No. 1 rotary conveyor line, and the inbound hydraulic station conveyor line along Inbound Route 1. The No. 1 rotary conveyor line, the inbound hydraulic station conveyor line, and the hydraulic station interact with the management system in real time through the TCP network.

[0016] In the above method for conveying stacked materials in linkage with a warehousing system, Step 7: After Step 6, the materials are sent to the hydraulic station. When the hydraulic station and the stacker receive the stacking task issued by the management system, the stacker is mobilized to stack the materials, and after the stacking is completed, the goods are taken in for storage.

[0017] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, after completing step 4.2, the RGV transfer vehicle 15 feeds materials along route 3. During this process, the RGV transfer vehicle interacts with the management system in real time through the TCP network. If the RGV transfer vehicle receives a material return task issued by the management system, step 4.21 is performed;

[0018] Step 4.21: The RGV transfer vehicle moves along route 4 and stacks and returns the materials to the turntable.

[0019] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, after completing step 4.21, the turntable feeds back the material information to the management system. The management system issues a scheduling task and identifies the destination of the stacked material information through the management system, manual identification, or a wireless barcode scanner;

[0020] If an outbound task is issued, step 4.1 is performed;

[0021] If a re-inbound task is issued, the materials pass through the No. 2 rotary conveyor line and the chain conveyor in sequence along route 2 to the No. 1 rotary conveyor line, and then step 6 is performed to transfer the materials to the hydraulic station through the No. 1 rotary conveyor line and the inbound hydraulic station conveyor line.

[0022] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, the stacker is located between the outbound hydraulic station conveyor line and the inbound hydraulic station conveyor line.

[0023] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, the chain conveyor is a device that drives the materials to move horizontally through a chain.

[0024] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, the turntable is located on one side of the outbound hydraulic station conveyor line. The turntable rotates 90° for docking with the RGV transfer vehicle.

[0025] In the above-mentioned method for conveying stacked materials in linkage with a warehousing system, the stacker and the management system establish data communication with the control system PLC through the S7 communication protocol, and send the operating status of each component according to the content of the communication message.

[0026] Compared with the existing technology, the advantages of the present invention are as follows:

[0027] The processes of feeding, returning, storing, and outbound are automated, and all receive information from the warehousing management system, RGV transfer vehicle information, automated storage information through Ethernet communication, record and feedback system information, and can make flexible countermeasures for each piece of information, greatly reducing manual intervention and improving the working efficiency of the storage and production line.

Specific implementation mode

[0031] The present invention will be further described in detail below in conjunction with the drawings and specific implementation modes.

[0032] This embodiment provides a method for stacking and conveying materials in linkage with a warehousing system, in combination with Figure 1-2 as shown;

[0033] Step 1: The management system monitors in real time. When materials are detected in the warehouse, the stacker 11 is mobilized to stack the materials;

[0034] Step 2: The stacker 11 sorts and stacks the materials, and transports the stacked materials to the hydraulic station through the outbound hydraulic station conveyor line 12. During this process, the stacker 11, the outbound hydraulic station conveyor line 12, and the hydraulic station interact and feedback the outbound information to the management system in real time through the TCP network;

[0035] Step 3: The management system receives the feedback from the hydraulic station that the material stacking information has been received by the management system, issues the task of the material stacking outbound hydraulic station through the management system, and identifies the destination of the material stacking information through the management system, manual identification, or wireless scanner identification;

[0036] Step 4.1: If the outbound task is issued after Step 3 is completed, it is transported to the connecting conveyor line 14 along the No. 2 line 13 and taken out to complete the outbound. The connecting conveyor line 14 interacts with the management system in real time through the TCP network;

[0037] Step 4.2: If it is sent to production after Step 3 is completed, a delivery request is sent to the RGV transfer vehicle 15, and it is transported to the turntable 16 along the No. 2 line 13. After the RGV transfer vehicle 15 receives the signal, it moves to the turntable 16 to dock with the turntable 16 and receive the stacked materials.

[0038] The connecting conveyor line 14 is used for both the outbound path and the inbound path. When the connecting conveyor line 14 detects that there is a material placed, it identifies the material through the management system, manual identification, or a wireless barcode scanner. If the identification information is an outbound task, then proceed to step 4.1. If the identification information is an inbound information, then proceed to step 5;

[0039] Step 5: The management system issues an inbound task and conducts an appearance inspection on the material. If the appearance inspection is unqualified, then remove the material to make the inbound task fail; if the appearance inspection is qualified, then proceed to the inbound step.

When the hydraulic station and the stacker 11 receive the stacking task issued by the management system, then mobilize the stacker 11 to stack the material, and after stacking is completed, pick up the goods and put them into storage.

[0042] After completing step 4.2, the RGV transfer vehicle 15 delivers the material according to the No. 3 line 20. During this process, the RGV transfer vehicle 15 interacts with the management system in real-time through the TCP network. If the RGV transfer vehicle 15 receives the return material task issued by the management system, then proceed to step 4.21;

[0043] Step 4.21: The RGV transfer vehicle 15 moves according to the No. 4 line 21 and stacks and returns the material to the turntable 16.

[0044] After completing step 4.21, the turntable 16 feeds back the material information to the management system. The management system issues a scheduling task and identifies the destination of the material stacking information through the management system, manual identification, or a wireless barcode scanner;

[0045] If the issued task is an outbound task, then proceed to step 4.1;

[0046] If the issued task is a re-inbound task, then make the material pass through the No. 2 rotary conveyor line 22 and the chain conveyor 23 to the No. 1 rotary conveyor line 17 in sequence according to the No. 2 line 13, and then proceed to the transfer to the hydraulic station through the No. 1 rotary conveyor line 17 and the inbound hydraulic station conveyor line 19 in step 6.
