Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional warehouses, in particular to a three-dimensional warehouse. Background Art

[0002] At present, the domestic high-performance polyethylene fiber production mostly adopts the gel method to produce ultra-high molecular weight polyethylene fiber. Generally, a two-step method is adopted, using mineral oil as the first solvent, that is, the oil-containing gel yarn produced by spinning is collected in a barrel, balanced and static for a period of time, the mineral oil in the gel yarn seeps out and is discharged, and then the required ultra-high molecular weight polyethylene fiber is obtained by drawing. Balanced static is an important link in the production of ultra-high molecular weight polyethylene. This link requires a large number of gel yarn barrels for turnover, and a large area is required to place barrels and drain oil. At the same time, when drawing is required, it is necessary to manually find the required gel yarn barrel for drawing. This process is time-consuming and labor-intensive, occupies a large area, has poor environmental hygiene, and has high labor intensity.

[0003] At present, the oil in the frozen gel yarn barrel is manually drained. After draining the oil, it needs to be manually pushed to the designated position again for balance. In addition, the oil that seeps out after balancing cannot be drained in time, and the frozen gel yarn may even be soaked in oil, affecting the quality of the finished fiber. The discharge of the frozen gel yarn barrel requires a large area, and it takes a long time to find the designated barrel when using the frozen gel yarn barrel. The hand valve of the frozen gel yarn barrel has the probability of leakage, which makes the ground slippery, the on-site hygiene is poor, and there is a high safety risk of people slipping. The difficulty of pushing the barrel is standardized, and the frozen gel yarn barrels often bump into each other, and the formation of the frozen gel yarn in the barrel deteriorates. After large-scale production, due to the poor balancing and static time, a large number of frozen gel yarn barrels are required for turnover, which occupies a large area and is difficult to find barrels manually, which greatly restricts the work efficiency of this link.

[0030] Step 8: A liquid receiving funnel is provided under each three-dimensional storage barrel platform to receive the liquid automatically discharged from the drain barrel and finally transfer it to the liquid accumulation pool;

[0031] Step 9: When the drain barrel on the main structure of the three-dimensional warehouse needs to be unloaded, the unloading is completed through the control of the uniform unloading algorithm;

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] Example 1

[0053] When the drain bucket 10 falls onto the three-dimensional storage bucket platform 60 on the storage position, the drain bucket 10 automatically performs the draining operation.

[0054] In the invention, the draining bucket 10 is used to hold the material to be drained, and the material to be drained is held in the draining bucket 10 for draining.

[0055] Specifically in this embodiment, for the convenience of description, the material to be drained is ultra-high molecular weight polyethylene fiber jelly thread (referred to as "jelly thread"), and the drained liquid is mineral oil.

[0056] The drainage barrel 10 includes a spinning barrel shell 11, a barrel bottom plate 12 is provided at the bottom of the spinning barrel shell 11, a seepage filter 13 is installed inside the spinning barrel shell 11, a gap is provided between the seepage filter 13 and the barrel bottom plate 12, a drainage hole 121 is provided on the barrel bottom plate 12, an automatic reset drain valve 90 is installed below the drainage hole 121, and the automatic reset drain valve 90 is connected to the drainage hole 121.

[0058] The stacker is conventional and generally includes a stacker body, a stacker overhead rail 22 , a stacker floor rail 23 , and a stacker barrel taking platform 21 . The stacker barrel taking platform 21 is provided with a fork for forking the leachate barrel 10 .

[0059] The three-dimensional warehouse barrel loading platform 60 includes a barrel loading frame 61 and a guide slider 64 installed on the top of the barrel loading frame 61. Four guide sliders 64 are provided, and the four guide sliders 64 respectively match the four corners of the bottom of the drain bucket 10; the guide slider 64 includes a barrel loading plate 642 and a guide plate 641, and the barrel loading plate 642 and the guide plate 641 are connected to form an L-shaped structure.

[0060] A barrel bearing wheel 14 is also installed at the bottom of the spinning barrel shell 11 , and an RFID chip 15 is installed outside the side wall of the spinning barrel shell 11 .

[0066] The setting of the horizontal hook 931 can ensure that the plunger 92 can be driven to move upward during the falling process. The inclined plate 93 is inclined, so that it has a certain fault tolerance and can slowly open the automatic reset liquid discharge valve 90 to avoid damage caused by sudden opening and closing.

[0067] Example 3

[0068] The three-dimensional warehouse also includes a control system, which includes an intelligent algorithm module. The intelligent algorithm module has built-in storage location allocation algorithm, exit distance priority algorithm, and uniform outbound algorithm.

[0069] A method for using a stereoscopic library comprises the following steps:

[0070] Step 1. The ultra-high molecular weight polyethylene fiber jelly yarn produced by spinning is connected to the seepage filter 13 of the drain barrel 10. The seepage filter and the outer shell of the drain barrel are made of stainless steel to ensure that the oil is not contaminated. The seepage filter is made of holes on a stainless steel plate with a hole diameter of 2.5mm and a hole spacing of 10mm*10mm to ensure that the mineral oil on the jelly yarn can seep out and flow to the bottom plate 12 of the barrel body in time. When the inclined plate is subjected to a vertical upward external force, the reset spring is compressed, the automatic reset drain valve opens, and the seeped mineral oil flows from the drain port through the valve body of the automatic reset drain valve and is discharged; when the external force is removed, the reset spring recovers its deformation and closes the automatic reset drain valve. The automatic reset drain valve is sealed with polytetrafluoroethylene.

[0071] An RFID chip is attached to a fixed position on the outside of the drain barrel 10, and the production stores the relevant information in the RFID chip through MES for use by the three-dimensional warehouse system.

[0072] Step 2: Use AGV or forklift to move the drain bucket filled with ultra-high molecular weight polyethylene fiber jelly filaments to the loading and unloading platform 40; when the drain bucket falls, the limit slider 44 and the wheel block 42 are used to achieve precise positioning of the drain bucket, and the drain bucket is supported by the support column 43 of the loading and unloading platform.

[0073] Step 3, the loading and unloading platform 40 is provided with an RFID card reader 45. When the drain barrel is in place, the RFID chip on the drain barrel is just within the reading range of the RFID card reader. The control system reads the information carried by the RFID chip on the drain barrel through the RFID card reader. The control system realizes automatic allocation of the storage space of the drain barrel on the main structure 30 of the three-dimensional warehouse through the intelligent algorithm module, and issues instructions to control the stacker to transport the drain barrel on the loading and unloading platform to the designated storage space.

[0074] Step 4: Plan and determine the lane number according to the production line information of ultra-high molecular weight polyethylene fiber jelly yarn. To prevent stacker failure, the ultra-high molecular weight polyethylene fiber jelly yarn of each production line must be evenly distributed to the passage of each lane stacker. After determining the lane number, the leachate barrels are relatively concentrated to ensure the efficiency of outbound delivery.

[0075] The main structure of the three-dimensional warehouse has multiple aisles. The aisle numbers are numbered from the position close to the discharge port, starting from 1. The aisle number here is the aisle number that the corresponding stacker passes through. This is to evenly distribute each production line to different aisles.

[0076] The warehouse space to be allocated is determined based on the exit distance priority algorithm.

[0077] Lane determination method:

[0078] n i =n i-1 +1,n iis the lane number obtained by numbering the leachate barrel corresponding to the production of the i-th barrel of ultra-high molecular weight polyethylene fiber jelly yarn, i is an integer greater than 1, n1=1;

[0079] When n i >x, x refers to the total number of lanes, n i The value is changed to 1; for example, there are 5 lanes if there are 5 stackers, x=5; when the number corresponding to the drain barrel is calculated to be 6, its value is greater than 5, then the lane number of the drain barrel corresponding to the current production of the 6th barrel of ultra-high molecular weight polyethylene fiber jelly thread is changed to 1, and the cycle is repeated to ensure that the drain barrels of each production line are evenly distributed to each lane.

[0080] The export distance priority algorithm and the warehouse priority algorithm are: h = y c *λ+y l *β+n i *γ; h is the distance weight, y c is the number of storage spaces in the main structure of the three-dimensional warehouse, y l is the number of warehouse columns of the main structure of the three-dimensional warehouse; calculate the distance weight of each warehouse, sort the warehouses according to the distance weight to achieve the purpose of distance priority, λ is the distance between the layer where the current warehouse is located and the first layer, β is the distance between the column where the current warehouse is located and the first column, and γ is the distance between the lane where the current warehouse is located and the exit of the main structure of the three-dimensional warehouse.

[0081] Step 5. After the stacker receives the transport instruction from the control system, the stacker moves to the side of the loading and unloading platform and extends the fork under the drain barrel. After the fork is extended into place, the stacker's barrel retrieval platform moves up 120mm, allowing the fork to lift the drain barrel, and then the fork retracts to the stacker's barrel retrieval platform, and the drain barrel is placed on the retrieval platform together.

[0082] Step 6. After the stacker takes the barrel, it moves to the designated position on the ground rail. The fork carrying the drain barrel extends to 50 mm above the three-dimensional warehouse barrel loading platform of the designated position. The stacker barrel loading platform moves down 100 mm. During the descent, the guide slider realizes the precise positioning of the drain barrel on the three-dimensional warehouse barrel loading platform. The fork retracts and the stacker starts to execute the next step.

[0083] Step 7. The drain barrel is placed on the three-dimensional storage barrel platform. During the descent of the drain barrel, the inclined plate of the automatic reset drain valve touches the drain limit plate. Since the drain barrel is very heavy, weighing more than 500 kg, the inclined plate is lifted under the action of gravity and the automatic reset drain valve is opened.

[0084] Step 8. A liquid receiving funnel is set under each three-dimensional warehouse barrel platform to receive the mineral oil automatically discharged from the drain barrel and finally transfer it to the liquid accumulation pool; the liquid receiving funnel is conical, with an upper inner diameter of 256mm and a lower inner diameter of 40mm. It is made of stainless steel, and the liquid guiding inclined pipe is designed with an inclination of 10±2° to ensure the smooth flow of mineral oil. All liquid guiding branches are collected on the liquid guiding main pipe, and the mineral oil in the guiding main pipe finally flows into the liquid accumulation pool.

[0085] Step 9: When the drain barrel on the main structure of the three-dimensional warehouse needs to be shipped out, the post-spinning production line can issue a shipping task through the production MES or control system, and complete the shipping through the uniform shipping algorithm control; wherein, the shipping action is opposite to the storage action.

[0086] Uniform outbound algorithm: outbound priority = order priority * W1 + variety value * W2 + spinning production line value * W3 + time interval * W4 + distance weight * W5; order priority is determined according to the order and quantity of the production line orders. The production line that orders first has a higher priority than the production line that orders later, ensuring interval shipments and guaranteeing the demand for goods of each production line to avoid long waiting times; variety value and spinning production line value are determined according to the corresponding rules of the later spinning production line; time interval is determined by the difference between the entry time and the current time. The larger the difference, the higher the value. If the difference between the entry time and the current time is lower than the limit, the time interval = 0. The standing time of the frozen gel silk must comply with regulations. For example, it must be required to stand for more than 24 hours. If the calculated difference between the entry time and the current time is less than 24 hours, the time interval is set to 0, which greatly reduces its priority from the algorithm and prohibits outbound shipment; the distance weight is determined by formula 1. W1, W2, W3, W4, and W5 are all weight coefficients, and the order of size is W1>W2>W3>W4>W5, ensuring that the value of the previous item is higher than the value of the next item, and the weight decreases item by item.

[0087] In addition, it should be understood that those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

10. A method for using a stereoscopic library according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1, the leachate material is connected to the leachate filter of the leachate bucket; Step 2: Use AGV or forklift to move the drain bucket filled with the material to be drained to the loading and unloading platform; Step 3: The loading and unloading platform is provided with an RFID card reader. When the drain barrel is in place, the RFID chip on the drain barrel is just within the reading range of the RFID card reader. The control system reads the information on the RFID chip on the drain barrel through the RFID card reader. The control system realizes the automatic allocation of the bins of the drain barrels on the main structure of the stereoscopic warehouse through the intelligent algorithm module, and issues instructions to control the stacker to transport the drain barrels on the loading and unloading platform to the designated bins. Step 4: Determine the lane number according to the production line information planning of the material to be drained, and determine the storage location to be allocated according to the exit distance priority algorithm; Lane number determination method: n i =n i-1 +1,n i is the lane number obtained by numbering the drain barrel corresponding to the i-th barrel of material to be drained, i is an integer greater than 1, n1=1; When n i >x, x refers to the total number of lanes, n i The value is changed to 1; The exit distance priority algorithm is: h = y c *λ+y l *β+n i *γ; h is the distance weight, y c is the number of storage spaces in the main structure of the three-dimensional warehouse, y l is the number of bin columns of the main structure of the stereoscopic warehouse; calculate the distance weight of each bin, sort the bins according to the distance weight to achieve the purpose of distance priority, λ is the distance between the layer where the current bin is located and the first layer, β is the distance between the column where the current bin is located and the first column, γ is the distance between the lane where the current bin is located and the exit of the main structure of the stereoscopic warehouse; Step 5: After the stacker receives the transport instruction from the control system, the stacker moves to the side of the loading and unloading platform, extends the fork under the drain bucket, and after the fork is in place, the stacker moves up the bucket-picking platform to make the fork lift the drain bucket, and then the fork retracts to the stacker bucket-picking platform, and the drain bucket is placed on the pickup platform together; Step 6: After the stacker takes the barrel, it moves to the designated location on the ground rail, and the fork carrying the leachate barrel extends to the top of the three-dimensional warehouse barrel loading platform at the designated location. The stacker barrel taking platform moves down, the fork retracts, and the stacker starts to execute the next step; Step 7: The drain bucket is placed on the three-dimensional storage bucket platform. During the descent of the drain bucket, the inclined plate of the automatic reset drain valve touches the drain limit plate, the inclined plate is lifted, and the automatic reset drain valve is opened; Step 8: A liquid receiving funnel is provided under each three-dimensional storage barrel platform to receive the liquid automatically discharged from the drain barrel and finally transfer it to the liquid accumulation pool; Step 9: When the drain barrel on the main structure of the three-dimensional warehouse needs to be unloaded, the unloading is completed through the control of the uniform unloading algorithm; Uniform outbound algorithm: outbound priority = order priority * W1 + variety value * W2 + spinning production line value * W3 + time interval * W4 + distance weight * W5; the order priority is set according to the order and quantity of the production line orders, and the variety value and spinning production line value are set according to the corresponding rules of the post-spinning production line; the time interval is determined by the difference between the entry time and the current time. If the difference between the entry time and the current time is lower than the limit value, the time interval = 0; W1, W2, W3, W4, W5 are all weight coefficients, and the order of size is W1>W2>W3>W4>W5.
