Abstract

This application relates to a process layout for a rubber mixing workshop, comprising a masterbatch production area and a final refining production area located within the workshop. The final refining production area is situated on one side of the masterbatch production area along the rubber mixing production direction and is arranged separately. The masterbatch production area houses a masterbatch production line and an automated masterbatch warehouse, with the masterbatch rubber sheets produced by the masterbatch production line stored in the automated masterbatch warehouse. Similarly, the final refining production area houses a final refining production line and an automated final refining warehouse, with the final refining rubber sheets produced by the final refining production line stored in the automated final refining warehouse. Along the rubber mixing production direction, the masterbatch production line, the automated masterbatch warehouse, the final refining production line, and the automated final refining warehouse are arranged sequentially. This separate layout of the masterbatch production area and the final refining production area eliminates the need for back-and-forth transportation of masterbatch rubber sheets, reducing cross-contamination during transport, ensuring safety, and also reducing logistics distances and improving production efficiency.

Description

Technical Field

[0001] This application relates to the field of production workshop layout technology, and in particular to a process layout for a rubber mixing workshop. Background Technology

[0002] Rubber compounding is the process of uniformly dispersing various compounding agents into rubber using the mechanical force of a rubber compounding machine. The process involves uniformly dispersing these agents in rubber to form a multi-rubber mass dispersion system where rubber, or a mixture of rubber and compatible compounding components, serves as the medium, and incompatible compounding agents (such as carbon black, silica, and zinc oxide) are the dispersed phase. The product processed through this compounding process is called rubber compound. Rubber compound can account for over 80% of the weight of a tire, demonstrating that the quality of the compounding process has a decisive impact on the further processing of the rubber compound and the quality of the finished product.

[0003] Currently, the rubber mixing workshop design uses a traditional linear layout of internal mixers, with the masterbatch production line arranged first, followed by the final rubber mixing production line. According to process requirements, the masterbatch rubber must be stored according to process specifications after processing, and final mixing can only proceed after the storage time meets the requirements. In the traditional process, the masterbatch production line and the final mixing production line are set up in a row. The masterbatch rubber sheets produced by the masterbatch production line are transported to the second floor of the workshop via a conveyor belt from the sheet cooling device, and then transferred by forklift for storage. After the storage requirements are met, the sheets are then transported back to the masterbatch production line for multi-stage masterbatch processing or to the final mixing production line to produce semi-finished compound rubber, depending on process needs. However, this results in long logistics distances, large storage space requirements, and production stoppages due to conveyor belt malfunctions in the cooling device, leading to low production efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide a rubber mixing workshop process layout that can reduce logistics distance and improve production efficiency, addressing the problem of long logistics transportation distances caused by the current arrangement of master refining production lines and final refining production lines.

[0005] A rubber mixing workshop process layout includes a master refining production area and a final refining production area located in the rubber mixing workshop. The final refining production area is located on one side of the master refining production area along the rubber mixing production direction and is arranged separately.

[0006] The master refinery production area is equipped with a master refinery production line and a master refinery automated warehouse. The master refinery film produced by the master refinery production line is stored in the master refinery automated warehouse. The final refinery production area is equipped with a final refinery production line and a final refinery automated warehouse. The final refinery film produced by the final refinery production line is stored in the final refinery automated warehouse.

[0007] Along the rubber refining production direction, the masterbatch refining production line, the masterbatch refining automated warehouse, the final refining production line, and the final refining automated warehouse are arranged in sequence.

[0008] In one embodiment of this application, the masterbatch production line includes an auxiliary machine, a first internal mixer, a first tablet press, and a first film cooling device located in the masterbatch production area. The auxiliary machine is located above the first internal mixer, the first tablet press is located below the first internal mixer, and the first film cooling device is located between the first internal mixer and the masterbatch automated warehouse.

[0009] In one embodiment of this application, the masterbatch production area further includes a first automated transport device and a first stacker crane. The first stacker crane is arranged in a direction perpendicular to the first film cooling device. The first automated transport device moves back and forth between the first film cooling device and the first stacker crane. The first stacker crane is used to lift the masterbatch film conveyed by the first automated transport device into the masterbatch automated warehouse.

[0010] In one embodiment of this application, the masterbatch production area further includes a first transport channel, which is located between the first film cooling device and the masterbatch automated warehouse. The first transport channel is connected to the first stacker crane and is used for the movement of the first automated transport equipment.

[0011] In one embodiment of this application, the masterbatch production line further includes a clean water tank and a first lifting device. The clean water tank and the first lifting device are disposed between the first tablet press and the first film cooling device. The clean water tank is used to cool the masterbatch film, and the first lifting device is used to transport the masterbatch film output from the first tablet press to the first film cooling device.

[0012] In one embodiment of this application, the final refining production line includes a second internal mixer, a second tablet press, and a second film cooling device located in the final refining production area. The second internal mixer is disposed above the second tablet press, and the second film cooling device is disposed between the second tablet press and the final refining automated warehouse.

[0013] In one embodiment of this application, the masterbatch automated warehouse is located in the first and / or second floor area of ​​the rubber mixing workshop, the second internal mixer is located in the first and / or second floor area of ​​the rubber mixing workshop, and the entrance of the second internal mixer corresponds to the outbound station of the masterbatch automated warehouse.

[0014] In one embodiment of this application, a second automated transport device and a second stacker crane are provided in the final processing production area. The second stacker crane is arranged in a direction perpendicular to the second film cooling device. The second automated transport device moves back and forth between the second film cooling device and the second stacker crane. The second stacker crane is used to lift the final processed film transported by the second automated transport device to the final processing automated warehouse.

[0015] In one embodiment of this application, the final refining production area further includes a second transport channel located between the second film cooling device and the final refining automated warehouse. The second transport channel is connected to the second stacker crane and is used for the movement of the second automated transport equipment.

[0016] In one embodiment of this application, the masterbatch production line is arranged along the third floor area of ​​the rubber mixing workshop, the final mixing production line is arranged along the second floor area of ​​the rubber mixing workshop, and the final mixing automated warehouse is located on the first and second floors of the rubber mixing workshop.

[0017] The final refining production area also has a connecting corridor that links the automated final refining warehouse with the adhesive application workshop.

[0018] By adopting the above technical solution, this application has at least the following technical effects:

[0019] In the rubber mixing workshop process layout of this application, along the rubber mixing production direction, the final mixing production area is located on one side of the master mixing production area. The master mixing production area is equipped with a master mixing production line and a master mixing automated warehouse, and the final mixing production area is equipped with a final mixing production line and a final mixing automated warehouse. Along the rubber mixing direction, the master mixing production line, the master mixing automated warehouse, the final mixing production line, and the final mixing automated warehouse are arranged sequentially. The master mixing rubber sheets produced by the master mixing production line are stored in the master mixing automated warehouse. When the storage time of the master mixing rubber sheets in the master mixing automated warehouse meets the process requirements, the master mixing rubber sheets are transported to the final mixing production line for production. The final mixing rubber sheets produced by the final mixing production line are stored in the final mixing automated warehouse for use by the rubber-using workshop in the later stages.

[0020] The rubber mixing workshop is laid out with the masterbatch production area and the final refining production area separated. The masterbatch production equipment and automated masterbatch warehouse are located in the masterbatch production area, while the final refining production equipment and automated final refining warehouse are located in the final refining production area. These two production areas are arranged side-by-side. In this way, the masterbatch rubber sheets produced by the masterbatch production equipment are stored in the automated masterbatch warehouse, and masterbatch rubber sheets that have met the process requirements after storage are directly transported to the final refining production equipment in the final refining production area. This eliminates the need for repeated, back-and-forth transport of masterbatch and final refining rubber sheets, reducing logistics distance, improving production efficiency, minimizing cross-contamination during transportation, and ensuring production safety and reliability.

Detailed Implementation

[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0031] See Figures 1 to 3 This application provides a process layout for a rubber mixing workshop. This layout primarily involves arranging the locations of various types of rubber mixing equipment within the rubber mixing workshop 100, ensuring that these equipment are in relatively reasonable positions to meet the rubber mixing requirements of the workshop 100. Figure 1 This is a schematic diagram of the process layout of a rubber mixing workshop according to an embodiment of this application. Figure 2 for Figure 1 The diagram shown is a structural schematic of the masterbatch production area 110 in the rubber mixing workshop process layout. Figure 3 for Figure 1 The diagram shows the structure of the final refining production area 120 in the rubber mixing workshop process layout.

[0032] Understandably, in current rubber mixing workshops, the masterbatch production line and the final refining production line are arranged in a row. The masterbatch rubber sheets produced by the masterbatch production line need to be lifted, picked up, and weighed by a sheet cooling device, and then transferred by forklift for storage. After storage needs are met, they are transported back to the masterbatch production line or the final refining production line by forklift for further processing. However, this leads to overlapping logistics routes, longer distances, and increased equipment failure points, resulting in low production efficiency. Therefore, this application provides a novel process layout for rubber mixing workshops. After adopting the above-mentioned process layout, the rubber mixing workshop 100 can significantly reduce logistics distances and improve production efficiency. The following describes the specific layout of a rubber mixing workshop process layout according to an embodiment.

[0033] See Figures 1 to 3 In one embodiment, the rubber mixing workshop layout includes a masterbatch production area 110 and a final refining production area 120 located in the rubber mixing workshop 100. The final refining production area 120 is located on one side of the masterbatch production area 110 along the rubber mixing production direction and is arranged separately. The masterbatch production area 110 houses a masterbatch production line 200 and a masterbatch automated warehouse 300. The masterbatch rubber sheets produced by the masterbatch production line 200 are stored in the masterbatch automated warehouse 300. The final refining production area 120 houses a final refining production line 400 and a final refining automated warehouse 500. The final refining rubber sheets produced by the final refining production line 400 are stored in the final refining automated warehouse 500. Along the rubber mixing production direction, the masterbatch production line 200, the masterbatch automated warehouse 300, the final refining production line 400, and the final refining automated warehouse 500 are arranged sequentially.

[0034] To better describe the specific layout of the rubber mixing workshop process layout, this application uses... Figure 1 The direction shown is the reference. Figure 1 The height / vertical direction shown is up and down, the length direction is left and right, and the width direction is front and back. In the rubber mixing workshop 100, a masterbatch production area 110 and a final mixing production area 120 are set up. The masterbatch production area 110 is used for masterbatch processing of the rubber compound, and the final mixing production area 120 is used for final mixing of the rubber compound after masterbatch processing. Furthermore, the rubber mixing production direction is from left to right, and the masterbatch production area 110 is located to the left of the final mixing production area 120, that is, in... Figure 1 In the process, the masterbatch production area 110 is located on the left and the final refining production area 120 is located on the right. After the masterbatch film produced in the masterbatch production area 110 meets the process requirements, it is transported to the final refining production area 120 on the right for final refining.

[0035] Specifically, a masterbatch production line 200 and an automated masterbatch warehouse 300 are arranged in the masterbatch production area 110, and a final refining production line 400 and an automated final refining warehouse 500 are arranged in the final refining production area 120. Along the rubber refining production direction, the masterbatch production line 200, the automated masterbatch warehouse 300, the final refining production line 400, and the automated final refining warehouse 500 are arranged sequentially; that is, the final refining production line 400 is located to the right of the masterbatch production line 200, the automated masterbatch warehouse 300 is located between the masterbatch production line 200 and the final refining production line 400, and the automated final refining warehouse 500 is located to the right of the final refining production line 400. The automated masterbatch warehouse 300 is used to store the masterbatch rubber sheets produced by the masterbatch production line 200, and the automated final refining warehouse 500 is used to store the final refining rubber sheets produced by the final refining production line 400.

[0036] During operation, masterbatch production line 200 performs masterbatch processing on rubber compounds, producing masterbatch sheets. Understandably, these masterbatch sheets need to be stored for a certain period to stabilize their properties and meet subsequent manufacturing requirements; that is, the storage time of the masterbatch sheets must meet the process requirements before final processing. Therefore, the masterbatch sheets can be directly stored in the automated masterbatch warehouse 300 on the right. Once the storage time meets the process requirements, the masterbatch sheets are sent out of the automated masterbatch warehouse 300 and then transported to the final processing production line 400 for final processing. The final processed sheets produced by the final processing production line 400 are stored in the automated final processing warehouse 500 and then transported to the rubber-using workshop.

[0037] The rubber mixing workshop layout in the above embodiment adopts a separate arrangement of the masterbatch production area 110 and the final refining production area 120. The masterbatch production line 200 and the automated masterbatch warehouse 300 are located in the masterbatch production area 110, and the final refining production line 400 and the automated final refining warehouse 500 are located in the final refining production area 120. In this way, the masterbatch rubber sheets produced by the masterbatch production equipment are stored in the automated masterbatch warehouse 300, and the masterbatch rubber sheets that have been stored for the required time are directly transported to the final refining production equipment in the final refining production area 120. Thus, the masterbatch rubber sheets do not need to be transported back and forth, reducing cross-contamination during transportation, ensuring safety, and also reducing logistics transportation distance and improving production efficiency.

[0038] See Figures 1 to 3 In one embodiment, the rubber mixing workshop 100 has a structure with at least three layers in some areas. In this way, the height of the rubber mixing workshop 100 can meet the layout requirements of the masterbatch production line 200, the masterbatch automated warehouse 300, the final refining production line 400, and the final refining automated warehouse 500.

[0039] Optionally, the rubber mixing workshop 100 has a partially three-story structure. It can be understood that the rubber mixing workshop 100 is generally a two-story structure, with a partially three-story area 150 located on the far left. In this way, the masterbatch production line 200 is located on the far left and arranged vertically within the three-story rubber mixing workshop 100, the final mixing production line 400 is arranged vertically within the two-story rubber mixing workshop 100, and the automated masterbatch warehouse 300 and the automated final mixing warehouse 500 are located in the second-story area 140 of the rubber mixing workshop 100.

[0040] Of course, in other embodiments of this application, the rubber mixing workshop 100 may also be a three-story or more-story structure, as long as it can meet the layout requirements of the masterbatch production line 200, the masterbatch automated warehouse 300, the final mixing production line 400, and the final mixing automated warehouse 500.

[0041] It is worth noting that some equipment in the masterbatch production line 200 and the final refining production line 400 runs through the second-floor area 140 and / or third-floor area 150 of the rubber mixing workshop 100. That is, some equipment runs from the first-floor area 130 to the second-floor area 140, and some equipment runs from the first-floor area 130 to the third-floor area 150. In this case, it is necessary to install the equipment in the corresponding locations within the rubber mixing workshop 100, meaning that the second-floor areas 140 and 150 do not have floor slabs, to facilitate equipment installation. This arrangement will not be elaborated further below.

[0042] Optionally, the second-floor area 140 corresponding to the outbound station of the masterbatch automated warehouse 300 is set up to correspond with the inlet of the final refining production line 400. In this way, the masterbatch sheets that have been stored for the required time in the masterbatch automated warehouse 300 are transported to the inlet of the final refining production line 400 in the second-floor area 140, eliminating the need to collect and store the sheets in the first-floor area 130. This greatly reduces the material transportation distance, optimizes the complexity of logistics transportation, and facilitates material handling.

[0043] Optionally, the column grid in the first-floor area 130 of the rubber mixing workshop 100 is 7.5m × 8m, and the column grid in the second-floor areas 140 and the third-floor areas 150 is 15m × 8m. By increasing the column grid size in the second-floor areas 140 and the third-floor areas 150, the impact of the support columns in the rubber mixing workshop 100 on the transportation of rubber materials can be avoided, which is more conducive to the flexible planning of the path of the automated transportation equipment.

[0044] See Figures 1 to 3Optionally, the masterbatch automated warehouse 300 and the final refining automated warehouse 500 employ automated methods to control the entry, exit, and storage of rubber materials. That is, the masterbatch rubber sheets in the masterbatch automated warehouse 300 are stored automatically and with information technology, and the storage time of the masterbatch rubber sheets is recorded automatically and with information technology to ensure that the storage time of the masterbatch rubber sheets meets process requirements. Furthermore, the masterbatch rubber sheets that have met the storage time requirements are output automatically and with information technology. The final refining automated warehouse 500 similarly employs automated and information technology for storage. Optionally, the masterbatch automated warehouse 300 and the final refining automated warehouse 500 utilize an MES (Manufacturing Execution Management) system for digital control.

[0045] See Figure 1 and Figure 2 In one embodiment, the masterbatch production line 200 includes an upper auxiliary machine 210, a first internal mixer 220, a first tablet press 230, and a first film cooling device 240 located in the masterbatch production area 110. The upper auxiliary machine 210 is located above the first internal mixer 220, the first tablet press 230 is located below the first internal mixer 220, and the first film cooling device 240 is located between the first internal mixer 220 and the masterbatch automated warehouse 300.

[0046] The auxiliary machine 210 is used for feeding raw materials. This auxiliary machine 210 is located in the third-floor area 150 and the second-floor area 140 of the rubber mixing workshop 100. The first internal mixer unit 220 is located in the first-floor area 130 of the rubber mixing workshop 100, meaning that the first-floor area 130 to the third-floor area 150 are connected. Furthermore, the auxiliary machine 210 is located above the first internal mixer unit 220, and the first tablet press 230 is located below the first internal mixer unit 220. That is, the first tablet press 230 is located in a pit. The first film cooling device 240 is located to the right of the first internal mixer unit 220, and between the first internal mixer unit 220 and the automated masterbatch warehouse 300.

[0047] The auxiliary machine 210 feeds raw materials such as rubber compound into the first internal mixer unit 220, where the first internal mixer unit 220 performs mastering of the raw materials and conveys the mastered material to the first tablet press 230, where mastered rubber sheets are extruded. Subsequently, the mastered rubber sheets are conveyed to the first film cooling device 240 for cooling.

[0048] See Figure 1 and Figure 2Optionally, the upper auxiliary machine 210 includes a storage hopper 211, a weighing component 212, and a feeding component 213. The storage hopper 211 is disposed above the weighing component 212 and located above the first internal mixer unit 220. The feeding component 213 is located above the first internal mixer unit 220, and the weighing component 212 and the feeding component 213 are disposed corresponding to the first internal mixer unit 220.

[0049] Storage hopper 211 is used to store chemical raw materials such as carbon black and silica. Optionally, multiple storage hoppers 211 can be used to meet the storage needs of rubber compounds. Weighing component 212 is used to weigh carbon black and chemical raw materials. This ensures that the amount of rubber compounds entering the first internal mixer unit 220 meets the formulation requirements of the masterbatch. Feeding component 213 is used to weigh and feed rubber sheets.

[0050] Weighing component 212 weighs the raw materials in storage hopper 211 and then feeds them into the first internal mixer unit 220. Simultaneously, feeding component 213 weighs the film and feeds it into the first internal mixer unit 220, where the masterbatch process is carried out. It is worth noting that storage hopper 211, weighing component 212, feeding component 213, and the first film cooling device 240 are existing equipment and will not be described in detail here.

[0051] See Figure 1 and Figure 2 In one embodiment, the masterbatch production area 110 also has a first automatic transport device (not shown) and a first stacker 250. The first stacker 250 is arranged in a direction perpendicular to the first film cooling device. The first automatic transport device moves back and forth between the first film cooling device 240 and the first stacker 250. The first stacker 250 is used to lift the masterbatch film of the first automatic transport device into the masterbatch automated warehouse 300.

[0052] In other words, the first automated transport equipment can realize the round-trip transport of masterbatch sheets. Specifically, the first automated transport equipment moves from the first sheet cooling device 240 to the first stacker crane 250 to transport the masterbatch sheets cooled by the first sheet cooling device 240 to the first stacker crane 250; the first automated transport equipment can also move from the first stacker crane 250 to the first sheet cooling device 240 to return to the unloading station of the sheet cooling device to receive the masterbatch sheets cooled by the first sheet cooling device 240.

[0053] Optionally, when the first automated transport equipment transports masterbatch sheets, the masterbatch sheets can be placed directly on the first automated transport equipment. Alternatively, the first automated transport equipment can also accommodate the masterbatch sheets using pallets. When the first automated transport equipment returns to the first sheet cooling device 240, it carries the empty pallets back with it. Furthermore, the first stacker crane 250 is positioned along the height direction in the first-floor area 130 and the second-floor area 140 of the rubber mixing workshop 100. The first stacker crane 250 can lift the cooled masterbatch sheets from the first-floor area 130 to the automated masterbatch warehouse 300 in the second-floor area 140.

[0054] In other words, the automated masterbatch refining warehouse 300 has an inbound station and an outbound station. The inbound station is located in area 130 on the first floor, and the outbound station is located in area 140 on the second floor. The first stacker crane 250 is located at the inbound station. The masterbatch refining sheets cooled by the first sheet cooling device 240 are transported to the first stacker crane 250 via the first automatic transport equipment, and then lifted into the automated masterbatch refining warehouse 300 by the first stacker crane 250. This reduces the space occupied by the warehouse and improves the space utilization rate. At the same time, it also facilitates the output of masterbatch refining sheets from the automated masterbatch refining warehouse 300 to the final refining production line 400 from the outbound station, reducing the logistics transportation distance.

[0055] See Figure 1 and Figure 2 In one embodiment, the masterbatch production line 200 further includes a clean water tank and a first lifting device 260, which are disposed between the first tablet press 230 and the first film cooling device 240. The clean water tank is used to cool the masterbatch film, and the first lifting device 260 is used to transport the masterbatch film output from the first tablet press 230 to the first film cooling device 240. It is understood that the first tablet press 230 is located in a pit, and the first film cooling device 240 is located in a single-layer area 130. After the first lifting device 260 connects the first tablet press 230 and the first film cooling device 240, it can lift the masterbatch film extruded from the first tablet press 230 to the first film cooling device 240 for cooling. The specific structure of the first lifting device 260 is prior art and will not be described further here.

[0056] In one embodiment, the masterbatch production area 110 also has a first transport channel located between the first film cooling device 240 and the masterbatch automated warehouse 300. The first transport channel is connected to the first stacker crane 250 and is used for the movement of the first automated transport equipment.

[0057] Optionally, the first automated transport device is a rail-guided vehicle. Of course, in other embodiments of this application, the first automated transport device may also be a trackless transport vehicle. Optionally, the first automated transport device is one or more combinations of AGV, RGV, pallet conveying system, and articulated robot. That is, the first automated transport device can move in the first transport channel to transport masterbatch sheets; for example, the automated transport device transports the masterbatch sheets cooled by the first sheet cooling device 240 to the first stacker crane 250.

[0058] Optionally, the masterbatch production area 110 also has a third transport channel, located in front of the automated masterbatch warehouse 300 and connected to the final refining production line 400. This third transport channel is for the movement of a third automated transport device. This third automated transport device can move within the third transport channel to transport masterbatch sheets that meet storage requirements from the automated masterbatch warehouse 300 to the final refining production line 400 via the outbound station. It is worth noting that the third automated transport device is essentially the same as the first automated transport device, and will not be described further here.

[0059] See Figure 1 and Figure 2 In one embodiment, the first internal mixer unit 220 includes multiple internal mixers in series and multiple single internal mixers. The multiple internal mixers in series and the multiple single internal mixers are arranged sequentially along the rubber mixing production direction. Each internal mixer in series and each single internal mixer corresponds to a first tablet press 230. The internal mixers in series and the single internal mixers are used to prepare masterbatch sheets for different production processes. Furthermore, each internal mixer corresponds to a first tablet press 230, through which the material mixed in the internal mixer is extruded to form masterbatch sheets.

[0060] Optionally, the series internal mixer includes a master internal mixer and a slave internal mixer, with the master internal mixer positioned above the slave internal mixer. The material output from the master internal mixer is conveyed to the slave internal mixer for processing. Optionally, the first internal mixer group 220 also includes a standby internal mixer. Internal mixers are existing technology and will not be described in detail here.

[0061] See Figure 1 and Figure 3 In one embodiment, the final refining production line 400 includes a second internal mixer 410, a second tablet press 420, and a second film cooling device 430 located in the final refining production area 120. The second internal mixer 410 is disposed above the second tablet press 420, and the second film cooling device 430 is disposed in the second tablet press 420 and the final refining automated warehouse 500.

[0062] The second internal mixer unit 410 is located in the first and / or second floor area 140 of the rubber mixing workshop 100. The second sheeting machine 420 is located in the first floor area 130 of the rubber mixing workshop 100, below the second internal mixer unit 410. The second sheet cooling device 430 is located to the right of the second sheeting machine 420, between the second sheeting machine 420 and the final compound automated warehouse 500. An automated transport system conveys the masterbatch rubber sheets from the masterbatch automated warehouse 300 to the second internal mixer unit 410. After processing in the second internal mixer unit 410, the sheets enter the second sheeting machine 420, where the final compound rubber sheets are extruded. The final compound rubber sheets are cooled in the second sheet cooling device 430 before being conveyed to the final compound automated warehouse 500.

[0063] In one embodiment, the second internal mixer unit 410 is located in the first-floor area 130 and / or the second-floor area 140 of the rubber mixing workshop 100, and the entrance of the second internal mixer unit 410 corresponds to the masterbatch automated warehouse 300. That is, the second internal mixer unit 410 corresponds to the outbound station of the masterbatch automated warehouse 300. In this way, masterbatch rubber sheets in the masterbatch automated warehouse 300 can be directly transported to the second internal mixer unit 410 in the second-floor area 140 by automated transport equipment, reducing the logistics transportation distance. Optionally, the second internal mixer unit 410 includes multiple single-unit internal mixers.

[0064] See Figure 1 and Figure 3 In one embodiment, a second automated transport device and a second stacker crane 440 are provided in the final processing production area 120. The second stacker crane 440 is arranged perpendicular to the second cooling device 430. The second automated transport device reciprocates between the second film cooling device 430 and the second stacker crane 440, which is used to lift the final processed film transported by the second automated transport device to the final processing automated warehouse 500. The second stacker crane 440 is arranged vertically in the second-floor area 140 of the rubber mixing workshop 100, and is capable of lifting the cooled final processed film in the first-floor area 130 to the final processing automated warehouse 500 in the second-floor area 140. It is worth noting that the second automated transport device has the same principle and structure as the first automated transport device, and will not be described again here.

[0065] In other words, the final-process automated warehouse 500 has inbound and outbound workstations. The inbound workstation is located in area 130 on the first floor, and the outbound workstation is located in area 140 on the second floor and the mezzanine area between the first and second floors. The final-processed rubber sheets are transported to the adhesive-using workshop via a connecting corridor 160 (mentioned later). The second stacker crane 440 is located at the inbound workstation. The final-processed rubber sheets cooled by the second rubber sheet cooling device 430 are transported to the second stacker crane 440 via the second automated transport equipment, and then lifted into the second-floor final-process automated warehouse 500. This reduces the space occupied by the warehouse, improves space utilization, and facilitates the transport of the final-process automated warehouse 500 to the adhesive-using workshop.

[0066] In one embodiment, the final processing area 120 also has a second transport channel located between the second film cooling device 430 and the final processing automated warehouse 500. The second transport channel is connected to the second stacker crane 440 and provides space for the movement of a second automated transport device. The second automated transport device can move within the second transport channel to transport the final processed film.

[0067] See Figure 1 and Figure 3 In one embodiment, the final refining production line 400 further includes a clean water tank and a second lifting device 450, which are disposed between the second tablet press 420 and the second film cooling device 430. It is understood that the second tablet press 420 and the first film cooling device 240 are located in a single layer area 130, but there is a certain height difference between the second tablet press 420 and the second film cooling device. After the clean water tank and the second lifting device 450 connect the second tablet press 420 and the second film cooling device 430, they can lift the final refining film extruded by the second tablet press 420 to the second film cooling device 430 for cooling. The specific structure of the second lifting device 450 is prior art and will not be described further here.

[0068] See Figure 1 Forehead Figure 3 In one embodiment, the final processing production area 120 further includes a connecting corridor 160 that connects the final processing automated warehouse 500 and the adhesive application workshop. The connecting corridor 160 connects the final processing automated warehouse 500 and the adhesive application workshop in the second-floor area 140 to transport the final processed rubber sheets from the final processing automated warehouse 500 to the adhesive application workshop.

[0069] Optionally, the first-floor area 130 of the rubber mixing workshop 100 also includes a power distribution room to supply power to the various electrical devices in the rubber mixing equipment. Exemplarily, there are two power distribution rooms, one located in the masterbatch production area 110 and the other in the final mixing production area 120. Optionally, the second-floor area 140 of the rubber mixing workshop 100 also includes a rest area.

[0070] See Figures 1 to 3 In the process layout of the rubber mixing workshop of this application, the masterbatch production area 110 and the final mixing production area 120 are arranged separately, and the masterbatch automated warehouse 300 is arranged between the masterbatch production line 200 and the final mixing production line 400. This realizes that the logistics system works in conjunction with the automated transportation equipment to work in different areas, and eliminates the rubber return device in the traditional masterbatch rubber sheet cooling line. In this way, the masterbatch rubber sheets are collected in the first-floor area 130 and lifted to the masterbatch automated warehouse 300 in the second-floor area 140 with the cooperation of automated transportation equipment and stacker cranes. After the storage time in the masterbatch automated warehouse 300 meets the requirements, they are released from the warehouse in the second-floor area 140.

[0071] By optimizing the complexity of logistics organization, the risk of production stoppages due to equipment failure is reduced, and the impact of human intervention on product quality is minimized, thereby achieving the goals of cost reduction and increased product value. Simultaneously, it also reduces logistics transportation distances, improves production efficiency, reduces energy consumption, and decreases VOC emissions. Furthermore, by utilizing automated transport equipment in conjunction with the logistics system, real-time movement data and production information can be used to control the automated transport equipment, as well as the 300-unit automated masterbatch warehouse and the 500-unit automated final refining warehouse, reducing manual labor and labor intensity.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
