Description

Technical Field

[0001] The invention relates to the technical field of steel coil packaging and conveying, in particular to a steel coil packaging and conveying process and a production line. Background Art

[0002] The core coils after longitudinal shearing of the original steel coils are called cut-to-length steel coils. From an industry perspective, the existing traditional steel coil transmission and packaging usually adopts transportation equipment such as overhead cranes, gantry cranes and walking beams. These steel coil packaging conveyor lines generally have the disadvantages of occupying a lot of space, being bulky, requiring large investments, inflexible process operations, low safety, low packaging efficiency, and a messy and difficult to manage site, which often become the bottleneck of the entire production line.

[0003] With the increase in customer demand, especially for exported steel coil products, which are easily damaged during transportation due to long logistics and complex environment, more and more customers require better protection, and need to add external iron packaging to the products that have been automatically packed with anti-rust paper and film (i.e., simply packed steel coils). At present, in the production process of steel coil products with two different packaging requirements, automatic packaging lines are usually mixed together for packaging operations.

[0004] The products after cross-mixed packaging operation are first put into storage in the planned order. If there are products that need additional iron packaging, it is necessary to check the order, and then use a forklift to move the peripheral products, find the target products and transfer them to the temporary iron packaging site. This workload is very large, the efficiency is very low, it is very inconvenient, and it wastes a lot of manpower and material resources. In addition, during the transportation process, there are many processes and long distances. The steel coils are prone to secondary damage and have to be transported back to the warehouse after iron packaging.

[0005] In addition, there are many specifications of steel coils, and their iron sheet packaging steps involve many types of packaging materials. Due to the heavy weight of steel coils, the movement of steel coils during packaging and transportation in China currently mostly relies on crane cooperation, which is time-consuming and labor-intensive, very inefficient, and has great safety hazards. The packaging process and quality are difficult to control. The existing packaging and conveying operations also require sufficient space and the cooperation of multiple people, which makes it difficult to meet the needs of multi-specification products and multi-station operations at the same time, affecting the continuous operation of the automatic packaging line and the needs of timely delivery. Summary of the invention

[0006] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a steel coil packaging and conveying process and production line, which facilitates the conveying and packaging of simply packaged steel coils with different packaging requirements, reduces the overall space occupied by the packaging conveyor line, improves the flexibility and safety of the packaging process, and improves packaging efficiency.

[0007] The technical solution adopted by the present invention is as follows:

[0008] A steel coil packaging and conveying process comprises the following steps:

[0009] Steel coil information input:

[0010] The simply packaged steel coils from the upstream automatic packaging line are labeled and scanned by the labeling and scanning system, and the steel coil information is input into the MES system.

[0011] A tray is provided below the simply packaged steel coil, and the tray is used to support the simply packaged steel coil during transportation;

[0012] Simple packaging steel coil diversion:

[0013] After the packaging control system analyzes the steel coil information from the MES system, the simple-packaging steel coils from the upstream automatic packaging line enter the diversion mechanism.

[0014] The diversion mechanism transports the simply packaged steel coils that do not need to be wrapped with outer iron sheets to the bidirectional conveyor line, and then the bidirectional conveyor line transports them forward to the first warehouse.

[0015] The diversion mechanism transports the simply packaged steel coils that need to be wrapped in outer iron sheets to the one-way conveyor line, waiting to enter the front docking system that is connected to the one-way conveyor line;

[0016] Steel coil packaging iron sheet:

[0017] The front connection system is connected to a packaging area, in which a sheet metal packaging line and an internal auxiliary material operation system are arranged.

[0018] When the packaging control system calls the simply packaged steel coil to enter the packaging area, the simply packaged steel coil is transported to the entrance of the iron sheet packaging line through the front docking system, and then the simply packaged steel coil passes through the front buffer section of the iron sheet packaging line and enters the packaging station of the iron sheet packaging line, and is packaged with iron sheet at the packaging station to become an iron sheet wrapped steel coil;

[0019] Iron-clad steel coil conveying:

[0020] The iron sheet wrapped steel coils are transported from the packaging station to the rear buffer section located at the exit of the iron sheet packaging line.

[0021] When the packaging control system calls for the iron-clad steel coil to leave the packaging area, the iron-clad steel coil is transported to the temporary storage area through the rear docking system docked with the rear buffer section, and then transported to the second warehouse through the warehouse handling equipment;

[0022] Auxiliary material conveying:

[0023] The front docking system is also connected to a material preparation area, where the auxiliary materials required for packaging are placed on an auxiliary material rack. The material preparation area is provided with an external auxiliary material operation system that is docked with the front docking system.

[0024] When the packaging control system calls the auxiliary material rack loaded with auxiliary materials to enter the packaging area, the auxiliary material rack is transported to the front docking system through the external auxiliary material operation system, and then transmitted to the internal auxiliary material operation system through the front docking system. The internal auxiliary material operation system transports the auxiliary material rack loaded with auxiliary materials to one side of the iron sheet packaging line to put the auxiliary material rack in place;

[0025] Accessory rack recycling:

[0026] When the packaging control system calls an empty auxiliary material rack out of the packaging area, the empty auxiliary material rack is transported to the rear docking system through the internal auxiliary material operation system, and the empty auxiliary material rack is transported to one side of the material preparation area through the rear docking system, and then the external auxiliary material operation system puts the auxiliary material rack back to the material preparation area;

[0027] The bidirectional conveyor line, unidirectional conveyor line and sheet metal packaging line all adopt roller conveying method.

[0028] Its further technical solution is:

[0029] The following steps are also included:

[0030] Simple packaging steel coil reflow:

[0031] The simply packaged steel coils in the first warehouse are transported in reverse to the diversion mechanism via the bidirectional conveyor line, and then transported to the unidirectional conveyor line by the diversion mechanism.

[0036] The external auxiliary material operation system includes a first auxiliary material platform corresponding to the first vehicle, and also includes a first material rack transporting device for transporting the auxiliary material rack loaded with auxiliary materials to the first auxiliary material platform.

[0037] When the first auxiliary material platform is docked with the first vehicle, the auxiliary material rack on the first auxiliary material platform is transferred to the first vehicle.

[0038] When the first material rack handling device is docked with the second vehicle, the first material rack handling device transports the vacant auxiliary material rack on the second vehicle to the material preparation area;

The first roller assembly and the second roller assembly are installed on the substrate through a second lifting mechanism.

[0047] In the step of packaging steel coils with iron sheets: when the horizontal steel coils placed on the horizontal pallet are transported to the packaging station, the second lifting mechanism drives the first roller assembly and the second roller assembly to rise and contact the outer peripheral surfaces on both sides of the axis of the horizontal steel coils respectively.

[0048] The first lifting mechanism drives the roller conveyor platform to descend, so that the driving roller conveyor platform and the horizontal tray descend together, and the rotating roller assembly is higher than the roller conveyor platform, and the first roller assembly and the second roller assembly support the horizontal steel coil.

[0052] Then the rotating roller assembly is stopped, and the iron sheet is wrapped around the outside of the horizontal steel coil.

[0053] After the iron sheet packaging is completed, the first lifting mechanism and the second lifting mechanism are reset, the roller conveyor platform and the horizontal tray rise to the initial positions, and the first roller assembly and the second roller assembly fall to the initial positions.

[0054] There are multiple iron sheet packaging lines which are arranged side by side at intervals, and the internal auxiliary material operation system is located between two iron sheet packaging lines.

[0062] The bidirectional conveyor line, the unidirectional conveyor line and the sheet metal packaging line are all roller conveying lines. The diversion mechanism is a turntable structure for roller conveying, and the bidirectional conveyor line has a bidirectional conveying function.

[0068] The beneficial effects of the present invention are as follows:

[0069] The present invention has a compact and reasonable structure and is easy to operate. The entire packaging and conveying process mainly adopts a roller conveying method, which makes the overall structure of the conveyor line simple, facilitates safety protection, and reduces the overall space occupied by the packaging conveyor line; the simple packaging steel coils with various packaging needs upstream are diverted, and the products are positioned and conveyed, and are packaged and stored in a targeted manner. At the same time, the auxiliary material transportation and auxiliary material rack recovery functions are integrated into the conveying process, so that the handling tasks in the entire packaging conveyor line are reasonably distributed, the transportation process and space layout are reasonable, and the connection with the existing production line and warehouse is reasonable, which reduces the allocation of personnel, reduces the difficulty of operation, improves the flexibility of packaging process operation, and production efficiency, and reduces production costs.

[0070] At the same time, the present invention also has the following advantages:

[0071] (1) The bidirectional conveyor line transports the simply packaged steel coils from the first warehouse in reverse direction through the diversion mechanism and automatically enters the iron sheet packaging line. This not only realizes the two inventory functions of the first warehouse, but also combines the return of the simply packaged steel coils to make the packaging and conveying process flexible, as well as the flexible control of the output and demand of the iron sheet steel coils, so as to maximize the function of this packaging conveyor line.

[0072] (2) At the entrance of the iron sheet packaging line, that is, at the front buffer section, a secondary barcode printing management terminal is set up, which is easy to operate and reliable in function. After receiving the material at the packaging station and before packaging, the barcode on the steel coil product needs to be scanned to record the information of the simple packaging steel coil to be packaged, and then used to print the label for secondary labeling after packaging, which ensures the continuity of the steel coil information and facilitates traceability.

[0073] (3) By using a combination of a guide rail and a trolley that slides along the guide rail as a docking system, the production cost of the entire packaging conveyor line can be reduced. The maximum utilization of the docking system can be achieved by optimizing the control program according to the call situation, while the packaging area and the preparation area are closely connected.

[0074] (4) The specific number of the first trolley and the second trolley is one each, and they are reasonably allocated according to the working conditions. The auxiliary material racks are transferred by docking the trolley with the auxiliary material tables in the packaging area and the material preparation area. At the same time, the second material rack handling equipment and the first material rack handling equipment are used in the packaging area and the material preparation area respectively to flexibly transport the auxiliary material racks. While being able to meet the auxiliary material supply and on-site management, the utilization rate of the docking system is improved and the production cost of the entire packaging conveyor line is reduced.

[0075] (5) A liftable roller conveyor platform is provided at the packaging station for conveying pallets, which is in line with the entire line. A liftable roller assembly and a rotating roller assembly that can support and drive the horizontal steel coil to rotate are provided at the middle channel of the roller conveyor platform. By changing the relative position relationship between the rotating roller assembly, the roller assembly, the roller conveyor platform and the horizontal steel coil, the horizontal pallet and the horizontal steel coil are separated and rotated at the same time, which is convenient for the iron sheet wrapping operation, plays an auxiliary packaging role, ensures the safety of the horizontal steel coil iron sheet wrapping process, and enables the packaging station to realize the integration of the auxiliary packaging and conveying functions of the horizontal steel coil.

[0076] (6) Multiple sheet metal packaging lines are set up in the entire packaging and conveying process. Each sheet metal packaging line can also be equipped with multiple packaging stations to operate simultaneously. The internal auxiliary material operation system is located between the two sheet metal packaging lines, which greatly improves the utilization rate of the internal auxiliary material operation system.

[0077] (7) The entire packaging and conveying process mainly adopts roller conveying, which makes the overall structure of the conveyor line simple, facilitates safety protection and reduces the overall space occupied by the packaging conveyor line; the packaging area and the preparation area as well as the first warehouse and the second warehouse are compactly arranged and reasonably connected with the iron packaging line through the front and rear docking systems. The entire production line process space is reasonably laid out, saving space, and the path setting is flexible, which improves production efficiency and reduces production costs.

[0103] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0104] Embodiment 1:

[0105] like Figure 1-Figure 3 As shown, the steel coil packaging and conveying process of this embodiment includes the following steps:

[0106] Steel coil information input: The simply packaged steel coils from the upstream automatic packaging line 10 are labeled and scanned by the labeling and scanning system 1, and the steel coil information is input into the MES system. A pallet is arranged under the simply packaged steel coils, and the pallet is used to support the simply packaged steel coils during transportation.

[0107] Specifically, the steel coils that need to be packed with iron sheets are not tied with plastic steel bands at the end of the automatic packaging line 10. The products are transported to the iron sheet packaging line 6 together with the pallets. After the iron sheets and corner protectors are packed in the iron sheet packaging line 6, they are finally tied with steel bands. This reduces unnecessary processes and does not require repeated tying and removal of plastic steel bands. The steel coils that do not need to be packed with iron sheets need to be tied with plastic steel bands at the end of the automatic packaging line 10 before entering the first warehouse A.

[0108] The above-mentioned simply packaged steel coils are vertical steel coils or horizontal steel coils, and can also be applicable to both vertical steel coils and horizontal steel coils. The labeling and code scanning system 1 includes a labeling machine 11 and a code scanning machine 12 arranged on one side of the upstream automatic packaging line 10. The labeling machine 11 and the code scanning machine 12 are both automatically operated. The labeling and code scanning system 1 effectively manages the information of the simply packaged steel coils, and the steel coil information includes whether the simply packaged steel coils need to be packaged in iron sheets.

[0109] Diversion of simply packaged steel coils: After the packaging control system analyzes the steel coil information from the MES system, the simply packaged steel coils from the upstream automatic packaging line 10 enter the diversion mechanism 2. The diversion mechanism 2 transports the simply packaged steel coils that do not need outer iron sheet packaging to the two-way conveyor line 3, and then the two-way conveyor line 3 transports them forward to the first warehouse A. The diversion mechanism 2 transports the simply packaged steel coils that need outer iron sheet packaging to the unidirectional conveyor line 4, waiting to enter the front docking system 5 that is connected to the unidirectional conveyor line 4.

[0110] Specifically, the length and specific functions of the one-way conveyor line 4 are set according to actual needs, such as Figure 1-Figure 2 As shown, the one-way conveying line 4 includes a conveying section 41 and a lifting platform 42. The lifting platform 42 is used to solve the problem of the height difference between the upstream automatic packaging line 10 and the downstream iron sheet packaging line 6.

[0111] The transfer of simply packaged steel coils between the bidirectional conveyor line 3 and the first warehouse A can be completed by a forklift.

[0112] In addition, the diversion mechanism 2 can be a turntable structure for roller conveying, and the conveying direction of the simply packaged steel coils on it can be changed by rotating the turntable; the diversion mechanism 2 can also be a bidirectional roller conveyor line with a reversing function, and the conveying direction of the simply packaged steel coils can be changed by switching the conveying direction of the roller conveyor line. In order to effectively connect the system and divert products, the steel coil information is used to control the diversion mechanism 2 and its downstream equipment, so that the system can automatically identify the simply packaged steel coils of the upstream automatic packaging line 10, and transport them to the first warehouse A in a directional manner or to the second warehouse E after packaging iron sheets.

[0113] By setting up two conveying paths in the packaging conveyor line and sending the steel coil information to the packaging control system through the MES system, the products can enter the corresponding conveyor line according to their packaging type, thereby achieving the purpose of conveying and processing products of different packaging categories in a set of conveyor line systems, improving product transportation efficiency and sorting efficiency, and reducing the operating cost of the warehousing system.

[0114] Steel coils are packed with iron sheets: the front connection system 5 is connected to the packaging area B, in which the iron sheet packaging line 6 and the internal auxiliary material operation system 7 are arranged. When the packaging control system calls the simply packed steel coils to enter the packaging area B, the simply packed steel coils are transported to the entrance of the iron sheet packaging line 6 through the front connection system 5, and then the simply packed steel coils pass through the front buffer section 61 of the iron sheet packaging line 6 and enter the packaging station 62 of the iron sheet packaging line 6, and are packed with iron sheets at the packaging station 62 to become iron sheet packed steel coils.

[0115] Specifically, the iron sheet packaging line 6 is provided with multiple functional stations, including a front buffer section 61, a packaging station 62, and a rear buffer section 63 behind the packaging station 62. The packaging station 62 and the rear buffer section 63 can be multiple stations, and the rear buffer section 63 can be used as a temporary storage to make the iron sheet packaging line 6 more flexible and to receive the simple packaged steel coils from the front to a greater extent, so as to maintain the efficiency and continuity of production. The packaging control system includes a touch screen terminal provided at the iron sheet packaging line 6, which can be used to call the simple packaged steel coils, as well as call the iron sheet steel coils, auxiliary materials, and empty material racks in other steps.

[0116] In addition, when there is no packaging task, the rear buffer section 63 can be used as a storage area for wrapped iron sheets and steel coils or empty auxiliary materials 80, so that the materials can be placed in an orderly and flexible manner, which is convenient for corresponding adjustments and operations according to the tasks, and fully and effectively solves the problems of chaotic material stacking and high difficulty in on-site management in current packaging production.

[0117] Conveying of iron-clad steel coils: The iron-clad steel coils are transported from the packaging station 62 to the rear buffer section 63 located at the exit of the iron-clad packaging line 6. When the packaging control system calls the iron-clad steel coils to leave the packaging area B, the iron-clad steel coils are transported to the temporary storage area D through the rear docking system 9 docked with the rear buffer section 63, and then transported to the second warehouse E through the warehouse handling equipment.

[0118] Specifically, temporary storage area D is a roller conveyor line composed of multiple stations, which can conveniently transport the iron-wrapped steel coils to the second warehouse E. The first station in temporary storage area D is equipped with an automatic product weighing function, and the gross weight data of the product after packaging is automatically collected. The gross weight data can also be intuitively displayed on the large screen in the warehousing area, and recorded in the enterprise database in combination with the order information. The subsequent stations in temporary storage area D are cache positions. The setting of multiple cache positions makes it more convenient and faster to centrally transfer warehouse handling equipment (such as forklifts) located in the second warehouse E, which is convenient for forklifts to improve efficiency and overall arrangement.

[0119] Auxiliary material transportation: The front docking system 5 is also connected to the material preparation area C, where the auxiliary materials required for packaging are loaded on the auxiliary material rack 80. The material preparation area C is provided with an external auxiliary material operation system 8 that is docked with the front docking system 5. When the packaging control system calls the auxiliary material rack 80 loaded with auxiliary materials to enter the packaging area B, the auxiliary material rack 80 is transported to the front docking system 5 through the external auxiliary material operation system 8, and then transmitted to the internal auxiliary material operation system 7 through the front docking system 5. The internal auxiliary material operation system 7 transports the auxiliary material rack 80 loaded with auxiliary materials to one side of the iron sheet packaging line 6 to put the auxiliary material rack 80 in place.

[0120] Specifically, the auxiliary material rack 80 is used to pre-assemble auxiliary packaging materials and is placed on one side of the iron sheet packaging line 6, serving as an auxiliary material warehouse for the packaging station 62. There are many auxiliary materials for iron sheet packaging, which also take up a lot of space and are not easy to manage. They mainly include outer iron sheet, inner iron sheet, end guard plate, inner iron corner guard, outer iron corner guard, various pads, strapping steel belt, steel belt buckle, etc. Among them, the inner and outer iron sheets and end guard plates are the outermost layers of protection, protecting the steel coil and the inner packaging such as rust-proof paper and wrapping film. The inner and outer iron corner guards are used to protect the most vulnerable edges of the steel coil. The strapping pads prevent excessive local stress. The steel belt buckle and steel belt are used to fix the steel coil to ensure the reliable fixation of the corner guard and packaging materials and the circumferential and longitudinal strength requirements of the steel coil.

[0121] like Fig.14As shown, the auxiliary material rack 80 is a frame structure made of light and strong materials; the bottom is a transport part 801, which is convenient for forklift operation, and the transport part 801 is designed with forks from four directions; the upper part of the transport part 801 is provided with multiple auxiliary material layers 802 from bottom to top, the first layer can be placed on the pallet to place the inner and outer iron corner guards, the second layer can be placed on the pallet to place multiple layers of end guards and inner iron sheets, and the third layer can be placed on the bundling steel belts, etc.; the top of the auxiliary material rack 80 is provided with multiple auxiliary material boxes 803 for placing various pads and steel buckles and other auxiliary materials. The structure of the auxiliary material rack 80 is convenient for pre-batch, forklift operation and transportation, and also makes the materials more beautiful and easy to use after being placed in categories. The outer iron sheet is relatively long, and the material preparation personnel pre-cut and process it according to the length and width dimensions, and then place it separately on the wooden pallet and transport it to the work station.

[0122] Various packaging materials are cut and prepared nearby, and specially designed packaging material racks are used to deliver the prepared packaging sets to the packaging station 62 according to the station instructions, effectively solving the current problems of chaotic packaging material stacking in production and high difficulty of on-site 5S management.

[0123] Recovery of auxiliary material rack 80: When the packaging control system calls the empty auxiliary material rack 80 to leave the packaging area B, the empty auxiliary material rack 80 is transported to the rear docking system 9 through the internal auxiliary material operation system 7, and the empty auxiliary material rack 80 is transported to the side of the preparation area C through the rear docking system 9, and then the external auxiliary material operation system 8 puts the auxiliary material rack 80 back to the preparation area C.

[0124] In the above steps of wrapping the steel coil with iron sheet, conveying the steel coil wrapped with iron sheet, conveying the auxiliary materials and recycling the auxiliary material rack 80:

[0125] The front docking system 5 is docked with the one-way conveyor line 4, and the front docking system 5 is docked with the front buffer section 61 of the iron sheet packaging line 6, which is used to transport the simply packaged steel coils to the iron sheet packaging line 6; the rear docking system 9 docked with the rear buffer section 63 of the iron sheet packaging line 6 is used to transport the iron sheet steel coils to the second warehouse E; the front docking system 5 and the rear docking system 9 are respectively docked with the internal auxiliary material operation system 7 for the transfer of the required auxiliary materials and the empty auxiliary material racks 80 at the packaging area B; the front docking system 5 and the rear docking system 9 are respectively docked with the external auxiliary material operation system 8 for the transfer of auxiliary materials at the preparation area C and the recovery of the empty auxiliary material racks 80; the iron sheet packaging line 6, the internal auxiliary material operation system 7 and the external auxiliary material operation system 8 of this embodiment are effectively connected through the front docking system 5 and the rear docking system 9, and while sharing the conveying system, the transportation of products, auxiliary materials and other materials is reasonably allocated, and the auxiliary material transportation and auxiliary material rack recovery functions and packaging functions are integrated into one.

[0126] In this embodiment, the bidirectional conveyor line 3, the unidirectional conveyor line 4 and the iron sheet packaging line 6 are all roller conveyor lines. Centering and braking motors can be used at necessary workstations, and frequency conversion control and other methods can be used to ensure accurate positioning. Each path can be operated manually, semi-automatically and automatically according to actual needs. A single conveyor line can be controlled in sections to achieve both a transmission function and a product cache, which greatly guarantees the production continuity of the front-end automatic packaging line 10. The roller conveyor line has low energy consumption and low investment. The entire conveying equipment area is closed, beautiful and safe, and sound and light alarms, safety doors and other protection methods can be used. The packaging control system and the MES system are combined to realize the digital management of the entire packaging conveyor line transfer process. At the same time, it is combined with warehouse management to facilitate management and maintenance, and fully consider personnel and operation safety.

[0127] The entire packaging and conveying process mainly adopts roller conveying, which makes the overall structure of the conveyor line simple, facilitates safety protection and reduces the overall space occupied by the packaging conveyor line; the simple packaging steel coils with various packaging needs from the upstream are diverted, and the products are positioned and conveyed, and packaged and stored in a targeted manner. At the same time, the auxiliary material transportation and auxiliary material rack recovery functions are integrated into the conveying process, so that the handling tasks in the entire packaging conveyor line are reasonably distributed, the transportation process and space layout are reasonable, and the connection with the existing production lines and warehouses is reasonable, which reduces the allocation of personnel, reduces the difficulty of operation, improves the flexibility of packaging process operation, and production efficiency, and reduces production costs.

[0128] Embodiment 2:

[0129] like Figure 1-Figure 3 As shown, this embodiment further optimizes the steel coil packaging and conveying process based on the first embodiment, and also includes the following steps:

[0130] Simple packaging steel coil reflow:

[0131] The simply packaged steel coils in the first warehouse A are transported in reverse to the diversion mechanism 2 via the bidirectional conveyor line 3, and then transported to the unidirectional conveyor line 4 by the diversion mechanism 2.

[0132] Specifically, for pre-packaged products produced without orders, the packaging control system will first identify them and transport them to the first warehouse A for separate storage. When it is clear that iron sheet packaging is required, the packaging control system can transport the simply packaged steel coils to the diversion mechanism 2 and the unidirectional conveyor line 4 via the two-way conveyor line 3 for iron sheet packaging.

[0133] The bidirectional conveyor line 3 conveys the simply packaged steel coils from the first warehouse A in reverse direction through the diversion mechanism 2 and automatically enters the iron sheet packaging line 6, which not only realizes the two inventory functions of the first warehouse A, but also combines the return of the simply packaged steel coils to make the packaging and conveying process flexible, as well as the flexible control of the output and demand of the iron sheet steel coils, so as to maximize the function of this packaging conveyor line.

[0134] In the step of wrapping steel coils with iron sheets: the simply wrapped steel coils are scanned twice at the front buffer section 61, and the labels are printed at the rear buffer section 63 and the iron sheet wrapped steel coils are labeled twice.

[0135] Specifically, in the steel coil information input step, the simply packaged steel coil is labeled once and scanned once on the upstream automatic packaging line 10, which is used to establish the steel coil information and the one-to-one correspondence, so as to facilitate the management of all simply packaged steel coils.

[0136] In the step of packaging steel coils with iron sheets, a secondary barcode printing management terminal is set at the entrance of the iron sheet packaging line 6, that is, at the front buffer section 61, which is easy to operate and reliable in function. Before packaging at the packaging station 62 after receiving the material, it is necessary to first scan the barcode on the steel coil product to record the information of the simple packaging steel coil to be packaged, and use it to print the label for secondary labeling after packaging, which ensures the continuity of the steel coil information and facilitates traceability. In addition, the system will bind the information of the packaging station 62 to the packaging control system according to the number corresponding to the input packaging station 62. After the packaging of the packaging station 62 is completed, the corresponding station number can be selected to print and post the secondary barcode, which is used to ensure the reliable correspondence and scientific management of the barcodes and product information of different packaging stations 62.

[0137] Embodiment three:

[0138] like Figure 1-Figure 3 As shown, on the basis of the first and second embodiments, the steel coil packaging and conveying process is further optimized, the utilization rate of the front docking system 5 and the rear docking system 9 is improved, and the manufacturing cost of the packaging conveying line is further reduced under the premise of meeting the packaging and conveying functions, and the following improvements are made:

[0139] The structure of the front docking system 5 includes a first guide rail 52 arranged on the ground, on which a first trolley 51 is slidably mounted, and the first trolley 51 is used to dock with the one-way conveyor line 4, the front buffer section 61, the external auxiliary material operation system 8, and the internal auxiliary material operation system 7;

[0140] The structure of the rear docking system 9 includes a second guide rail 92 arranged on the ground, and a second trolley 91 is slidably mounted on the second guide rail 92. The second trolley 91 is used to dock with the rear buffer section 63, the internal auxiliary material operation system 7, and the external auxiliary material operation system 8.

[0141] Specifically, the first vehicle 51 of the front docking system 5 can change its position along the travel path of the first guide rail 52, thereby changing its docking relationship with other conveyor lines or operating systems, and the same is true for the rear docking system 9.

[0142] By adopting a combination of a guide rail and a trolley that slides along the guide rail as a docking system, the production cost of the entire packaging conveyor line can be reduced. The maximum utilization of the docking system can be achieved according to the call situation by optimizing the control program, and at the same time, the packaging area B and the preparation area C are closely connected.

[0143] Furthermore, the external auxiliary material operation system 8 and the internal auxiliary material operation system 7 are optimized to meet the auxiliary material supply and on-site management, optimize the configuration, and reduce the production cost of the entire packaging conveyor line. The specific plan is as follows:

[0144] The number of the first car 51 and the second car 91 are both one;

[0145] The external auxiliary material operation system 8 includes a first auxiliary material platform 81 corresponding to the first vehicle 51, and also includes a first material rack transporting device for transporting an auxiliary material rack 80 loaded with auxiliary materials to the first auxiliary material platform 81.

[0146] When the first auxiliary material platform 81 is docked with the first vehicle 51, the auxiliary material rack 80 on the first auxiliary material platform 81 is transferred to the first vehicle 51.

[0147] When the first material rack transporting device is docked with the second vehicle 91, the first material rack transporting device transports the vacant auxiliary material rack 80 on the second vehicle 91 to the material preparation area C;

[0148] The internal auxiliary material operation system 7 includes a second auxiliary material platform 71 and a third auxiliary material platform 72. The second auxiliary material platform 71 corresponds to the first trolley 51, and the third auxiliary material platform 72 corresponds to the second trolley 91. It also includes a second material rack handling device 73. The second material rack handling device 73 is used to transport the auxiliary material rack 80.

[0149] When the second auxiliary material platform 71 is docked with the first vehicle 51, the auxiliary material rack 80 on the first vehicle 51 is transferred to the second auxiliary material platform 71, and the second material rack transporting device 73 then transports the auxiliary material rack 80 to one side of the iron sheet packaging line 6 so that the auxiliary material rack 80 is in place.

[0150] When the third auxiliary material platform 72 is docked with the second vehicle 91 , the empty auxiliary material rack 80 on the third auxiliary material platform 72 is transferred to the second vehicle 91 .

[0151] The first trolley 51, the second trolley 91, the first auxiliary material platform 81, the second auxiliary material platform 71 and the third auxiliary material platform 72 are all roller conveying structures. Further, the first auxiliary material platform 81, the second auxiliary material platform 71 and the third auxiliary material platform 72 can be set as roller conveying structures that are convenient for forklift operation.

[0152] In the specific work:

[0153] When there is no material at the packaging station 62 and iron sheet packaging operations are required, a material call can be set on the touch screen terminal at the iron sheet packaging line 6 to call for simply packaged steel coils. When the material call conditions are met, the first vehicle 51 of the front docking system 5 will transport the simply packaged steel coils on the lifting platform 42 to the front of the front buffer section 61 of the corresponding iron sheet packaging line 6. A safety door is provided between the front buffer section 61 and the front docking system 5. The safety door is automatically interlocked. The safety door will only open when the simply packaged steel coils are in place and need to pass through, and will automatically close after passing.

[0154] When the packaging station 62 completes the iron sheet packaging, a call for the iron sheet steel coil can be set on the touch screen terminal at the iron sheet packaging line 6. When the material calling conditions are met, the safety door between the rear buffer section 63 and the rear docking system 9 is opened, and the second vehicle 91 of the rear docking system 9 transfers the iron sheet steel coil to the temporary storage area D.

[0155] Various materials for packaging are prepared in the material preparation area C. The material preparation area C is provided with material preparation equipment 82, which includes equipment such as shearing machines, and the first material rack handling equipment can be equipment such as forklifts. The auxiliary materials for packaging are manually classified and placed on the auxiliary material rack 80, which is beautiful and neat and convenient for operation. The auxiliary material rack 80 is transported to the first auxiliary material platform 81 via the first material rack handling equipment, ready to be called at any time.

[0156] When the packaging area B needs auxiliary materials, the auxiliary materials call can be set on the touch screen terminal at the iron sheet packaging line 6. When the material call condition is met, the first car 51 of the front docking system 5 moves to the front of the first auxiliary materials platform 81, and the conveying function of the first car 51 and the first auxiliary materials platform 81 is started. The auxiliary material rack 80 is transferred to the first car 51, and is transported to the second auxiliary material platform 71 by the first car 51, and enters the internal auxiliary material operation system 7 of the packaging area B. Then the auxiliary material rack 80 is transported to the side of the iron sheet packaging line 6 by the second material rack handling device 73 to put the auxiliary material rack 80 in place. The second material rack handling device 73 can be a manually operated forklift, which can be raised and lowered, and the fork can be extended. The packaging operation platform and the roller conveyor line are in the same plane. The forklift is flexible and convenient to transport, and the auxiliary material rack 80 in the packaging area B can be transported, placed and adjusted with simple operations.

[0157] When the packaging area B needs to transfer the empty auxiliary material rack 80 to the preparation area C, the second material rack handling device 73 places the empty auxiliary material rack 80 on the third auxiliary material platform 72, and the empty auxiliary material rack call can be set on the touch screen terminal at the iron sheet packaging line 6. When the material call condition is met, the second trolley 91 of the rear docking system 9 docks with the third auxiliary material platform 72, and the auxiliary material rack 80 is transferred to the preparation area C by the rear docking system 9. When the second trolley 91 carrying the auxiliary material rack 80 moves to the safety door on one side of the preparation area C, the safety door opens, and the first material rack handling device transports the auxiliary material rack 80 to the preparation area C.

[0158] In addition, when the rear buffer section 63 in the packaging area B serves as a cache position for the auxiliary material rack 80 , the auxiliary material rack 80 can also be transferred by docking the rear buffer section 63 with the second trolley 91 .

[0159] Specifically, the number of the first trolley 51 and the second trolley 91 is each one, and they are reasonably allocated according to the working conditions. The transportation of the auxiliary material rack 80 is achieved by docking the trolley with the auxiliary material table in the packaging area B and the preparation area C. At the same time, the second material rack handling equipment 73 and the first material rack handling equipment are respectively used in the packaging area B and the preparation area C to perform flexible handling operations on the auxiliary material rack 80. While meeting the auxiliary material supply and on-site management, the utilization rate of the docking system is improved and the production cost of the entire packaging conveyor line is reduced.

[0160] Embodiment 4:

[0161] The packaging conveyor line needs to package and convey simple packaged steel coils, including vertical steel coils and horizontal steel coils 601. In order to facilitate transmission in the conveyor line and protect the steel coils from damage, the vertical steel coils and horizontal steel coils 601 are placed on pallets. The iron sheet packaging of the vertical steel coils is relatively simple, and the circumferential outer iron sheet packaging can be directly completed by manual operation. In addition, because there is a pallet and inner packaging protection at the bottom, the bottom guard plate does not need to be installed, and the vertical steel coil does not need to be separated from the pallet. Therefore, the iron sheet packaging of the vertical steel coils does not require the use of auxiliary equipment, and the products can be directly transported to the subsequent stations after the packaging operation at the packaging station 62.

[0162] The steps for packaging horizontal steel coil 601 iron sheets are generally as follows: first, manually glue and overlap the outer iron sheet longitudinally, then wrap the outer iron sheet, close and fix the outer iron sheet circumferentially, then assemble the inner and outer corner guards and fix them with steel strips longitudinally and circumferentially through the coil eyes.

[0163] Since the outer circumference of the horizontal steel coil 601 contacts the pallet during transportation, the product and the pallet need to be separated first during packaging, and then the product steel coil needs to be repeatedly rotated and fine-tuned according to the packaging operation steps to carry out the packaging operation. If the packaging conveyor line can simultaneously meet the transportation and packaging of horizontal steel coils 601 and vertical steel coils, and the auxiliary packaging function is integrated in the packaging station 62, the compatibility of the packaging conveyor line will be further improved. In addition, in the process of wrapping the outer iron sheet, because the steel coil is heavy and easy to be damaged, especially for silicon steel coils, auxiliary packaging equipment is very important.

[0164] like Figure 1-Figure 13 As shown, based on the above embodiments, the functional configuration of the packaging conveyor line is further improved.

[0165] The structure of the packaging station 62 is as follows: it includes a roller conveyor table 623. The conveying direction of the roller conveyor table 623 is the same as the conveying direction of the iron sheet packaging line 6. A vertically penetrating channel 6233 is provided at the center of the roller conveyor table 623. The roller conveyor table 623 is installed on the upper part of the base assembly 624 through a first lifting mechanism 625. Above the middle of the base assembly 624 is a base plate 6241, which corresponds to the channel 6233. A rotating roller assembly 621 is installed in the middle of the base plate 6241. Above the base plate 6241 on one side of the rotating roller assembly 621 is a first idler roller assembly 622. Above the base plate 6241 on the other side of the rotating roller assembly 621 is a second idler roller assembly 627 parallel to the first idler roller assembly 622. The first idler roller assembly 622 and the second idler roller assembly 627 are installed on the base plate 6241 through a second lifting mechanism 626.

[0166] Specifically, the conveying surface of the roller conveyor table 623 with the channel 6233 provided at the center is in an overall shape of a rectangle with a hollow center, meeting the requirement of supporting the conveying tray. When the packaging station 62 is in the initial position, the lifting roller conveyor table 623, the first idler roller assembly 622, and the second idler roller assembly 627 are lower than or level with the conveying surface of the roller conveyor table 623. At the same time, the lifting roller conveyor table 623 is docked with the conveying lines before and after the packaging station 62.

[0167] The first lifting mechanism 625 is used to lift the roller conveyor table 623, and the second lifting mechanism 626 is used to lift the first idler roller assembly 622 and the second idler roller assembly 627. The rotating roller assembly 621 is installed on the base plate 6241 in the middle of the base assembly 624. The first idler roller assembly 622, the second idler roller assembly 627, and the rotating roller assembly 621 can move relative to the roller conveyor table 623 in the channel 6233.

[0168] The first lifting mechanism 625 and the second lifting mechanism 626 can adopt driving methods such as hydraulic pressure and motors to realize the lifting function of the roller conveyor table 623 and the idler roller assemblies.

[0169] In the steps of packaging the steel coil with iron sheet: when the horizontal steel coil 601 placed on the horizontal tray 602 is transported to the packaging station 62, the second lifting mechanism 626 drives the first idler roller assembly 622 and the second idler roller assembly 627 to rise and contact the outer peripheral surfaces on both sides of the axis of the horizontal steel coil 601 respectively.

[0170] Specifically, sensors such as travel switches can be provided on the first idler roller assembly 622 and the second idler roller assembly 627. When the sensors contact the outer peripheral surface of the simply packaged steel coil, the second lifting mechanism 626 stops.

[0171] The first lifting mechanism 625 drives the roller conveying platform 623 to descend, so that the driving roller conveying platform 623 and the horizontal tray 602 are lowered together, and then the rotating roller assembly 621 is higher than the roller conveying platform 623, and at the same time, the first roller assembly 622 and the second roller assembly 627 support the horizontal steel coil 601;

[0172] Then the second lifting mechanism 626 drives the first roller assembly 622 and the second roller assembly 627 to descend until the horizontal steel coil 601 cooperates with the rotating roller assembly 621, the second lifting mechanism 626 stops, the horizontal steel coil 601 is separated from the first roller assembly 622 and the second roller assembly 627, and the first roller assembly 622 and the second roller assembly 627 are located on both sides of the lower part of the horizontal steel coil 601 to prevent the horizontal steel coil 601 from tipping over during the rotation process.

[0173] Specifically, after the sensors arranged on the first roller assembly 622 and the second roller assembly 627 fail to detect the contact with the horizontal steel coil 601, the second lifting mechanism 626 stops. At this time, there is a certain gap between the first roller assembly 622 and the second roller assembly 627 and the outer peripheral surface of the horizontal steel coil 601, so that the iron sheet can pass through the lower part of the horizontal steel coil 601.

[0174] The rotating roller assembly 621 is started, and the rotating roller assembly 621 supports the horizontal steel coil 601 and drives the horizontal steel coil 601 to rotate;

[0175] Then one end of the iron sheet is sent from one side of the rotating roller assembly 621 into the contact surface between the horizontal steel coil 601 and the rotating roller assembly 621, and the iron sheet is sent out from the other side of the rotating roller assembly 621 as the horizontal steel coil 601 rotates;

[0176] Then the roller assembly 621 is stopped from rotating, and the iron sheet is wrapped around the outside of the horizontal steel coil 601;

[0177] After the iron sheet packaging is completed, the first lifting mechanism 625 and the second lifting mechanism 626 are reset, the roller conveyor 623 and the horizontal tray 602 rise to the initial positions, and the first roller assembly 622 and the second roller assembly 627 fall to the initial positions.

[0178] When the horizontal steel coil 601 arrives at the packaging station 62, the packaging control system will automatically control the action of the packaging station 62 according to the product data.

[0179] In addition, the structure of the horizontal pallet 602 needs to leave space for the first roller assembly 622, the second roller assembly 627 and the rotating roller assembly 621 to move up and down relative to the horizontal pallet 602. Figure 6 As shown, the horizontal tray 602 may specifically have the following structure:

[0180] The horizontal tray 602 includes a bottom support 6021 that cooperates with the transmission surface of the roller conveyor platform 623. Two support rods 6022 are arranged on the bottom support 6021. The two support rods 6022 are parallel to each other and symmetrically arranged about the axis of the horizontal steel coil 601. The two support rods 6022 are also matched with the outer peripheral surface of the horizontal steel coil 601. When the horizontal steel coil 601 is transported to the packaging station 62, the rotating roller assembly 621 is located below between the two support rods 6022, and the first roller assembly 622 and the second roller assembly 627 are respectively located below the outer sides of the support rods 6022.

[0181] A liftable roller conveyor platform 623 is provided at the packaging station 62 for conveying pallets to fit the entire line; a liftable roller assembly and a rotating roller assembly 621 that can support and drive the horizontal steel coil 601 to rotate are provided at the middle channel 6233 of the roller conveyor platform 623; by changing the relative position relationship between the rotating roller assembly 621, the roller assembly and the roller conveyor platform 623 and the horizontal steel coil 601, the horizontal pallet 602 and the horizontal steel coil 601 are separated and rotated at the same time, which is convenient for the iron sheet wrapping operation, plays an auxiliary packaging role, ensures the safety of the horizontal steel coil 601 during the iron sheet wrapping process, and enables the packaging station 62 to realize the integration of the auxiliary packaging and conveying functions of the horizontal steel coil 601.

[0182] like Figure 1 , Figure 2 As shown, further, there are multiple iron sheet packaging lines 6 which are arranged side by side and spaced apart, and the internal auxiliary material operation system 7 is located between two iron sheet packaging lines 6 .

[0183] In the whole packaging and conveying process, a plurality of sheet metal packaging lines 6 are arranged, and each sheet metal packaging line 6 can also be provided with a plurality of packaging stations 62 for simultaneous operation. The internal auxiliary material operation system 7 is located between the two sheet metal packaging lines 6, which greatly improves the utilization rate of the internal auxiliary material operation system 7.

[0184] Two sheet metal packaging lines 6 and four packaging stations 62 are arranged on the left and right sides of the packaging operation platform, and packaging operations can be performed simultaneously. This two-line four-station arrangement can fully meet the maximum production cycle of the upstream automatic packaging line 10. The two packaging operation lines can also be arranged as one for work and one for standby, and each roller station of the standby sheet metal packaging line 6 can be used to place multiple sets of auxiliary material racks 80 with packaging auxiliary materials, which increases the flexibility of the system and reduces the operation frequency of the material preparation personnel.

[0185] The further improvement scheme about the structure of the packaging station 62 is as follows:

[0186] like Figure 7-Figure 9As shown, the roller conveyor platform 623 includes a frame 6234 with a hollow structure, and long rollers 6231 are respectively arranged at both ends of the frame 6234 along the conveying direction. A plurality of short rollers 6232 are symmetrically arranged on both sides of the middle part of the frame 6234 along the conveying direction. The short rollers 6232 on one side are arranged side by side along the conveying direction. The long rollers 6231 and the short rollers 6232 form a square shape, and the middle part of the square shape is a channel 6233. A first transmission motor 6235 is installed on one side of the frame 6234, and the long rollers 6231 and the short rollers 6232 are transmission-connected to the first transmission motor 6235 after being transmission-connected.

[0187] Specifically, a driving gear 6236 is provided at the end of the long roller 6231 and the end of the short roller 6232 on one side of the conveying direction. The driving gears 6236 are connected to each other through a chain and then connected to the first transmission motor 6235, so that the long roller 6231 and the short roller 6232 on this side rotate in the same direction; a linkage gear 6237 is provided at the end of the short roller 6232 on the other side of the conveying direction, and the linkage gears 6237 are connected to each other through a chain; a transition gear 6238 is provided at the other end of a long roller 6231 adjacent to the short roller 6232, and the transition gear 6238 is connected to the adjacent linkage gear 6237, so that the driving force of the first transmission motor 6235 is indirectly transmitted to the short roller 6232 on the other side, so as to realize the setting of a vertically through channel 6233 in the middle of the roller conveying platform 623 while ensuring the stable transmission function of the conveying plane of the roller conveying platform 623.

[0188] like Figure 10-13 As shown, the structure of the base assembly 624 is as follows: it includes a base 6242 , and a substrate 6241 is installed on the upper middle portion of the base 6242 .

[0189] The structure of the first lifting mechanism 625 is: it includes a second transmission motor 6255 fixedly installed on the base 6242, and also includes a first screw lift 6251, a second screw lift 6252, a third screw lift 6253 and a fourth screw lift 6254 evenly installed on the upper part of the base 6242. The first screw lift 6251 and the third screw lift 6253 are connected by a worm gear pair transmission, and the second screw lift 6252 and the fourth screw lift 6254 are connected by a worm gear pair transmission.

[0190] The output end of the second transmission motor 6255 is connected to a reducer 6256, which is also connected to the worm gear pair of the first screw lift 6251 and the second screw lift 6252. The screw pair ends of the first screw lift 6251, the second screw lift 6252, the third screw lift 6253 and the fourth screw lift 6254 are all connected to the bottom of the roller conveyor platform 623, specifically to the bottom of the frame 6234.

[0191] Furthermore, the transmission connection structure is:

[0192] The output ends of the reducer 6256 are respectively connected to the worm gear pairs of the first screw lift 6251 and the second screw lift 6252 through connecting shafts;

[0193] The worm gear pair of the first screw lift 6251 and the worm gear pair of the third screw lift 6253 are installed with gears and connected through a chain transmission;

[0194] The worm gear pair of the second screw lift 6252 and the worm gear pair of the fourth screw lift 6254 are installed with gears and are connected through a chain drive.

[0195] like Figure 11-Figure 12 As shown, the first roller assembly 622 has the same structure as the second roller assembly 627. The first roller assembly 622 comprises a support plate 6222 and a first roller 6221, wherein the first roller 6221 is mounted on the support plate 6222 via a bearing seat.

[0196] Specifically: the first roller assembly 622 and the second roller assembly 627 are non-powered structures, which are driven up by the second lifting mechanism 626 to hold up the horizontal steel coil 601, and are driven down to the two sides of the horizontal steel coil 601 by the second lifting mechanism 626 to play a role in assisting the horizontal steel coil 601 in the iron sheet packaging process.

[0205] like Figure 1-Figure 2 As shown, the steel coil packaging and conveying production line of this embodiment includes an upstream automatic packaging line 10, and a labeling and scanning system 1 is arranged on one side of the upstream automatic packaging line 10. The end of the upstream automatic packaging line 10 is connected to a bidirectional conveying line 3 through a diversion mechanism 2, and the bidirectional conveying line 3 leads to the first warehouse A.

[0206] The diversion mechanism 2 is also connected to a one-way conveying line 4 , and the end of the one-way conveying line 4 is connected to a front docking system 5 .

[0207] A packaging area B and a material preparation area C are arranged on the same side of the front docking system 5 , and the material preparation area C is adjacent to the packaging area B.

[0208] The packaging area B includes a plurality of sheet iron packaging lines 6 arranged at intervals. The sheet iron packaging lines 6 are used for packaging simple packaged steel coils and caching sheet iron wrapped steel coils. The entrance of a single sheet iron packaging line 6 is connected to the front docking system 5. An internal auxiliary material operation system 7 is arranged between two sheet iron packaging lines 6, and the internal auxiliary material operation system 7 is connected to the front docking system 5.

[0209] An external auxiliary material operation system 8 connected to the front docking system 5 is provided in the material preparation area C. The external auxiliary material operation system 8 is used to transport auxiliary material racks 80.

[0210] The packaging and conveying production line also includes a rear docking system 9 arranged in parallel with the front docking system 5 . The rear docking system 9 is connected to the outlet of the single iron sheet packaging line 6 , and the internal auxiliary material operation system 7 is connected to the rear docking system 9 .

[0211] The rear docking system 9 is located on the same side of the packaging area B and the material preparation area C. The rear docking system 9 is connected to the external auxiliary material operation system 8. A second warehouse E is set at the end of the rear docking system 9. The other side of the rear docking system 9 is the other area F of the workshop.

[0212] The bidirectional conveyor line 3, the unidirectional conveyor line 4 and the sheet metal packaging line 6 are all roller conveying methods, the diversion mechanism 2 is a turntable structure of roller conveying, and the bidirectional conveyor line 3 has a bidirectional conveying function.

[0213] Specifically, the first warehouse A is used to store simply packaged steel coils that do not need to be packaged in iron sheets. For pre-packaged products without orders, the packaging control system first identifies them and transports them to the first warehouse A for separate storage. When iron sheets need to be packaged, they enter the iron sheet packaging line 6 through the bidirectional conveyor line 3. The second warehouse E is used to store steel coils wrapped in iron sheets.

[0214] The simply packaged steel coils from the one-way conveyor line 4 are transported to the sheet metal packaging line 6 through the front docking system 5, and the sheet metal wrapped steel coils are transported to the second warehouse E through the rear docking system 9.

[0215] Two adjacent packaging lines can also be set up as one for work and one for standby, and each roller station of the standby iron sheet packaging line 6 can be used to place multiple sets of auxiliary material racks 80 with packaging auxiliary materials, which increases the flexibility of the system and reduces the operation frequency of the material preparation personnel.

[0216] A temporary storage area D is set between the rear docking system 9 and the second warehouse E for caching the iron-wrapped steel coils.

[0217] The packaging area B and the material preparation area C are arranged adjacent to each other, and the transportation of auxiliary materials and the control of the transportation of auxiliary materials racks 80 are realized through the docking interaction of the internal auxiliary materials operation system 7 located in the packaging area B, the external auxiliary materials operation system 8 located in the material preparation area C and the front and rear docking systems.

[0218] The entire packaging and conveying process mainly adopts roller conveying, which makes the overall structure of the conveyor line simple, facilitates safety protection and reduces the overall space occupied by the packaging conveyor line; the packaging area B and the preparation area C as well as the first warehouse A and the second warehouse E are compactly arranged, and are reasonably connected with the iron packaging line 6 through the front and rear docking systems. The entire production line process space is reasonably laid out, saving space, and the path setting is flexible, which improves production efficiency and reduces production costs.

[0219] The structure of the front docking system 5 includes a first guide rail 52 arranged on the ground, a first trolley 51 is slidably mounted on the first guide rail 52, and the first trolley 51 is docked with the entrance of the single iron sheet packaging line 6.

[0220] The structure of the rear docking system 9 includes a second guide rail 92 arranged on the ground, a second trolley 91 is slidably mounted on the second guide rail 92, and the second trolley 91 is docked with the outlet of the single iron sheet packaging line 6.

[0221] The internal auxiliary material operation system 7 includes a second auxiliary material platform 71 corresponding to the first trolley 51 and a third auxiliary material platform 72 corresponding to the second trolley 91, and also includes a second material rack handling device 73, the second material rack handling device 73 is used to carry the auxiliary material rack 80, the second material rack handling device 73 is docked with the first trolley 51 for transferring the auxiliary material rack 80 loaded with auxiliary materials, and the second material rack handling device 73 is docked with the second trolley 91 for transferring the empty auxiliary material rack 80.

[0222] The external auxiliary material operation system 8 includes a first auxiliary material platform 81 arranged on one side of the first guide rail 52 and corresponding to the first trolley 51, and also includes a first material rack handling device for transporting the auxiliary material rack 80. The first material rack handling device is docked with the second trolley 91 for transferring empty auxiliary material racks 80.

[0223] The first trolley 51 and the second trolley 91 are rationally deployed according to the working conditions, and the transportation of the auxiliary material rack 80 is realized by docking the trolley with the auxiliary material table in the packaging area B and the preparation area C. At the same time, the second material rack handling equipment 73 and the first material rack handling equipment are respectively used in the packaging area B and the preparation area C to carry out flexible handling operations of the auxiliary material rack 80. While meeting the auxiliary material supply and on-site management, the configuration is optimized to reduce the production cost of the entire packaging conveyor line.

[0224] In addition, the entire packaging conveyor line is carefully considered, combining the industry, existing workshop layout and product characteristics, and has been designed for safety protection from at least the following aspects:

[0225] First, for the roller conveyor line, steel plates are installed in the middle of each conveyor roller to keep it flat and convenient for people to stand and work safely. The photoelectric equipment is hidden and well-made to prevent people from touching and stepping on it. The packaging conveyor line equipment must have loads, instructions and tasks, and photoelectric sensing must be in place before it can operate. This control ensures that the sensor will not malfunction due to interference, and ensures that the packaging operation of the personnel will not trigger the roller to start and cause safety hazards. Each transmission roller can be manually controlled in forward and reverse rotation, and has independent operation functions, making product transmission flexible and path control flexible. Necessary safety interlocks are set between various operations.

[0226] Secondly, anti-collision devices and product anti-dropping mechanical devices are installed on the turntable of the roller conveyor of the diversion mechanism 2, the docking position of the conveyor line and the trolley, and the docking interface between the material rack handling equipment and the auxiliary material table. A touch screen terminal is set on one side of the single iron sheet packaging line 6. The control mode 1 of the terminal is manual operation, that is, both start and stop are manually operated, and mode 2 is fixed-point start, that is, the destination station is manually set on the touch screen.

[0227] Again, the product is heavy-loaded, and safety must be considered in particular, so the first trolley 51 and the second trolley 91 are semi-automatically controlled, that is, the start is manually operated and the stop is automatically stopped. The call trolley start condition is that there is something at the starting station and the destination station is empty. The corresponding transfer process can be started only when the condition is met. For example, when the first trolley 51 is at the starting position, the one-way conveyor line 4 transports the simple packaged steel coil to the first trolley 51. When the first trolley 51 is not at the starting position, the end of the one-way conveyor line 4 does not move.

[0228] Safety doors are provided at the entrance and exit of the single sheet metal packaging line 6, and the safety doors are roller shutter door structures. The first trolley 51 is linked to the safety door at the entrance of the single sheet metal packaging line 6, and the second trolley 91 is connected to the safety door at the exit of the single sheet metal packaging line 6. When the trolley is started, there will be an audible and visual alarm and the safety door will be opened. When the call is successful, the trolley will automatically pick up the goods. When the trolley arrives at the designated unloading station, in order to ensure safety, the operator needs to press and hold the start button. If the operator releases the start button, the trolley will stop running immediately.

[0229] The first car 51 and the second car 91 run on the track of the lane. Guardrails are set on both sides of the lane to prevent irrelevant personnel from entering and ensure personal safety. The closed lane has an inspection opening, and a single iron sheet packaging line 6 is provided with a movable cover to facilitate maintenance of related equipment.

[0230] Finally, for stations that require precise positioning, such as the packaging station 62, the packaging conveying system is equipped with fine-adjustment guide rods for constraining the product direction on both sides of the roller conveying structure upstream of the packaging station 62. The guide rods use the conveying force to fine-tune the product conveying direction to ensure that the position of the simply packaged steel coil meets the centering requirements when entering the packaging station 62, so that the auxiliary packaging function at the packaging station 62 can accurately act on the steel coil.

[0231] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
