The balance and standing is an important link in the production of ultrahigh molecular weight polyethylene, which needs a large number of gel silk barrels for turnover, needs a large area to put the barrels and discharge the oil, and at the time of drawing, the needed gel silk barrel is found out manually for drawing, which is time-consuming and laborious, occupies a large area, has poor environmental sanitation, and has high labor intensity.

[0003] The current gel silk barrel is manually discharged, and after discharging, the gel silk barrel needs to be manually pushed to the designated position for balance again, and the seeped oil after balance cannot be discharged in time, and even the gel silk is immersed in oil, which affects the quality of fiber products. The gel silk barrel needs a large area for discharge, and when the specified barrel is found during the use of the gel silk barrel, it takes a long time. The hand valve of the gel silk barrel has a leakage probability, which causes the ground to be wet and slippery, the on-site sanitation is poor, and the safety risk of personnel slipping is high. The difficulty of pushing the barrel by personnel is not standardized, and the gel silk barrel is often knocked, and the gel silk in the barrel is formed poorly.

[0058] The stacker crane is an existing conventional type, which typically includes a stacker crane body, a stacker crane overhead rail 22, a stacker crane ground rail 23, and a stacker crane bucket-retrieving platform 21, wherein the stacker crane bucket-retrieving platform 21 is equipped with forks for picking up the drain buckets 10.

[0059] The automated storage and retrieval system (AS / RS) platform 60 includes a container frame 61 and guide sliders 64 mounted on the top of the container frame 61. There are four guide sliders 64, which are respectively matched with the four corners of the bottom of the draining container 10.

[0061] The loading and unloading platform 40 includes a platform frame 41, a wheel stop 42 installed on the top of the platform frame 41 to limit the barrel bearing wheel 14, a support column 43 installed on the top of the platform frame 41, a limiting slider 44 installed on the top of the platform frame 41 to limit the bottom of the drain barrel 10, and an RFID reader 45 that matches the RFID chip 15.

[0067] Example 3

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

[0069] A method for using an automated storage and retrieval system includes the following steps:

[0070] Step 1, the UHMWPE fiber gel spinning produced by the spinning production is connected to the leaching filter screen 13 of the leaching barrel 10, the leaching filter screen and the leaching barrel shell are made of stainless steel material to ensure that the oil is not contaminated. The leaching filter screen is made of a perforated stainless steel plate with a hole diameter of 2.5 mm and a hole distance of 10 mm*10 mm, which ensures that the mineral oil on the gel yarn can be timely leached out and flow to the barrel bottom plate 12. When the inclined plate is subjected to a vertical upward external force, the reset spring is compressed, the automatic reset drainage valve is opened, the leached mineral oil flows through the valve body of the automatic reset drainage valve and is discharged from the drainage port; when the external force is removed, the automatic reset drainage valve is closed due to the recovery of the reset spring. The automatic reset drainage valve uses polytetrafluoroethylene sealing.

[0071] The RFID chip is attached to the outside of the leaching barrel 10, and the related information is stored in the RFID chip by MES for use by the three-dimensional warehouse system.

[0072] Step 2, the leaching barrel filled with UHMWPE fiber gel yarn is transported to the loading and unloading platform 40 by AGV or forklift; the leaching barrel is precisely positioned by the limiting slide block 44 and the wheel stop 42 when it falls, and the leaching barrel 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 leaching barrel is in place, the RFID chip on the leaching 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 leaching barrel through the RFID card reader, and the control system realizes the automatic allocation of the leaching barrel in the position of the three-dimensional warehouse main structure 30 through the intelligent algorithm module, and sends instructions to control the stacker to transport the leaching barrel on the loading and unloading platform to the specified position.

[0074] Step 4, according to the production line information planning of UHMWPE fiber gel yarn, the tunnel number is determined, in order to prevent the stacker from malfunctioning, the UHMWPE fiber gel yarn of each production line needs to be evenly distributed to the channel walked by each tunnel stacker, after the tunnel number is determined, in order to ensure the efficiency of the warehouse, the leaching barrels are relatively concentrated when leaving the warehouse.

[0075] The three-dimensional warehouse main structure has multiple tunnels, the tunnel number is numbered from the position close to the discharge port, starting from 1, the tunnel number here is the tunnel number corresponding to the passage of the stacker, which is to evenly distribute each production line to different tunnels.

[0076] According to the export distance priority algorithm, the position to be allocated is determined.

[0077] Tunnel determination method:

[0078] n i =n i-1 +1, n iis the tunnel number obtained by numbering the corresponding drip tank when producing the i-th bucket of ultra-high molecular weight polyethylene fiber gel yarn, i is an integer greater than 1, n1=1;

[0079] When n i >x, x refers to the total number of tunnels, n i is modified to 1; for example, there are 5 stackers, so there are 5 tunnels, x=5; when the corresponding number of the drip tank is calculated as 6, the value is greater than 5, so the tunnel number of the drip tank corresponding to the current production of the 6th bucket of ultra-high molecular weight polyethylene fiber gel yarn is changed to 1, and so on, to ensure that the drip tanks of each production line are evenly distributed to each tunnel.

[0080] The export 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 layers of the main structure of the stereoscopic warehouse, y l is the number of columns of the main structure of the stereoscopic warehouse; the distance weight of each position is calculated, and the positions are sorted according to the distance weight to achieve the purpose of distance priority, λ is the distance between the current position and the first layer, β is the distance between the current position and the first column, and γ is the distance between the current position and the exit of the main structure of the stereoscopic warehouse.

[0081] Step 5, after receiving the conveying instruction of the control system, the stacker moves to the side of the loading and unloading platform, and the fork is extended to the lower side of the drip tank. After the fork is extended to the position, the stacker takes the tank platform up by 120mm, so that the fork lifts the drip tank, and then the fork is retracted to the stacker tank platform, and the drip tank is placed on the loading platform.

[0082] Step 6, after the stacker takes the tank, the fork carrying the drip tank is extended to the upper side of the specified position of the stereoscopic warehouse tank platform by 50mm, and the stacker tank platform is lowered by 100mm. During the lowering process, the guide slider realizes the accurate positioning of the drip tank on the stereoscopic warehouse tank platform, the fork is retracted, and the stacker starts to perform the next action.

[0083] Step 7, the drip tank is placed on the stereoscopic warehouse tank platform. During the lowering process of the drip tank, the inclined plate of the automatic reset liquid discharge valve touches the liquid discharge limiting plate. Because the drip tank is very heavy, above 500Kg, under the action of gravity, the inclined plate is lifted, and the automatic reset liquid discharge valve is opened.

[0084] Step 8, each stereoscopic library carrying bucket platform is provided with a liquid receiving funnel, which receives the mineral oil automatically discharged from the leaching bucket and finally transfers the mineral oil to the liquid accumulation pool; the liquid receiving funnel is conical, with an inner diameter of 256mm at the upper opening and an inner diameter of 40mm at the lower opening, made of stainless steel, and the liquid guide inclined pipe is designed with an inclination angle of 10±2° to ensure smooth flow of the mineral oil. All liquid guide branch pipes converge to the liquid guide main pipe, and the mineral oil in the liquid guide main pipe finally flows into the liquid accumulation pool.

[0085] Step 9, when the leaching bucket on the main structure of the stereoscopic library needs to be discharged, the rear spinning production line can issue a discharge task through the production MES or control system, and the discharge is completed through the uniform discharge algorithm; wherein, the discharge action is opposite to the storage action.

[0086] Uniform discharge algorithm: discharge priority = order priority * W1 + variety value * W2 + spinning production line value * W3 + time interval * W4 + distance weight * W5; the order priority is determined according to the order and quantity of the production line order, and the priority of the production line with the order first is higher than that of the production line with the order later, so as to ensure interval delivery and meet the demand of each production line, and avoid long waiting time; the variety value and the spinning production line value are determined according to the corresponding rules of the rear spinning production line; the time interval is determined by the difference between the storage time and the current time, the larger the difference, the higher the value, if the difference between the storage time and the current time is less than the limited value, the time interval = 0, the time for the gelatinous silk to stand still must meet the requirements, such as more than 24 hours, if the difference between the storage time and the current time is less than 24 hours, the time interval is set to 0, which greatly reduces the priority of the algorithm and prohibits discharge; the distance weight is determined by formula 1. W1, W2, W3, W4 and W5 are weight coefficients, and the size order is W1> W2> W3> W4> W5, which ensures that the value of the former is higher than that of the latter, and the weight value decreases item by item.

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