Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, and in particular to an online automatic packaging process for waste produced continuously by a stamping production line. Background Art

[0002] Traditional waste treatment methods mainly rely on a combination of manual and mechanical equipment. Although these methods have been applicable in the past, with the improvement of production efficiency and environmental protection requirements, their shortcomings are becoming increasingly apparent.

[0003] The traditional stamping waste treatment process is mainly divided into five steps: 1. Online collection. The online collection of stamping waste is to transfer the waste generated during the stamping process from the production line to the waste collection area through a conveyor belt, waste trough or other conveying equipment. This process is usually carried out continuously to ensure the smooth operation of the production line; 2. Waste transportation. The collected waste is loaded into waste boxes or containers by manual or mechanical means, and then transported to the waste treatment station by vehicle for further treatment. This step is the first transportation of waste; 3. Secondary treatment. At the waste treatment station, the collected waste needs to be secondary treated. Common methods include magnetic separation, manual sorting and mechanical separation. Magnetic separation is mainly used to separate ferromagnetic materials in metal waste, while manual sorting is to manually classify waste of different materials; 4. Waste packaging. The classified waste is compressed into blocks by manually operated hydraulic balers for easy transportation and remelting; 5. Block remelting. The packaged waste blocks are transported to the smelter by vehicle for remelting, which is the secondary transportation of waste.

[0004] The existing stamping waste treatment method has the following defects: due to its manual operation and multiple transportation, it has the disadvantages of low efficiency, high cost, environmental pollution and safety hazards. Summary of the invention

[0005] The purpose of the present invention is to provide an online automatic packaging process for waste materials based on continuous production of a stamping production line, so as to overcome the shortcomings of the prior art.

[0006] The object of the present invention is achieved by: an online automatic packaging process for waste materials continuously produced by a stamping production line, including a packaging execution process, the packaging execution process including the following steps:

[0007] S1. Using the upper transport component to receive the waste transported by the waste conveyor chain, and then transporting the waste to the hopper of the storage and weighing component for temporary storage;

[0008] S2. When the waste in the material storage weighing component accumulates to the weight set by the program, the hopper automatically opens and releases the waste downward, so that the waste enters the packaging silo of the automatic packaging component below. After the automatic packaging program is started, the packaging work begins, and the automatic packaging component is used to compress the waste into a package block of a predetermined shape;

[0009] S3, after the packaging is completed, the package block is pushed out from the discharge port of the automatic packaging component, so that the package block enters the discharge coding component, and the label code is sprayed on the surface of the package block by the discharge coding component;

[0010] S4. Use the lower conveyor line to transport the bales to the loading position, and use automatic loading equipment to load the bales.

[0011] Furthermore, the label code in step S3 at least includes the material, weight, and batch information of the corresponding package.

[0012] Furthermore, for the two production lines, two production lines are defined as Line A and Line B respectively; before the packaging execution process, the online packaging control system collects data from Line A and Line B, and collects the number of modules and parts of the corresponding materials and the amount of waste for a single stamping part; then the data analysis step is performed, and data table statistics are performed to confirm whether the waste can meet the automated production conditions of the packaging line.

[0013] Furthermore, in the data analysis step, there are two working conditions: the first working condition is that lines A and B produce different aluminum parts, and the second working condition is that lines A and B produce the same aluminum parts; in this step, the corresponding packaging strategy is generated according to the above two working conditions, and the following formula is proposed:

[0014] Value = current batch production quantity ╳ Waste weight ╳ (Aluminum block packaged recycling value - bulk material recycling value);

[0015] Among them, the definition of Value is the added value brought;

[0016] Define Value(A) as the added value brought by Line A, and Value(B) as the added value brought by Line B.

[0017] Furthermore, when lines A and B produce different aluminum parts, the generated packaging strategy is as follows:

[0018] If Value(A)>Value(B), then the aluminum material of line A will be packed online, and the bulk material of line B will be received by car or other transportation equipment;

[0019] If Value(A)≤Value(B), the aluminum material of line B will be packaged online, and the bulk material of line A will be received by car or other transportation equipment.

[0020] Furthermore, when lines A and B produce the same aluminum parts, the generated packaging strategy is as follows:

[0021] When Waste(A)+Waste(B)>the capacity of a single baler, the values ​​of Value(A) and Value(B) are calculated, and the line with the heavier weight is baled, while the other line uses a car or other transportation equipment to receive the materials;

[0022] If Waste(A)+Waste(B)≤capacity of a single baler, then Line A and Line B share a waste baling line;

[0023] Wherein, Waste(A) is defined as the weight of waste generated by line A, and Waste(B) is defined as the weight of waste generated by line B.

[0024] Further, in step S4 of the packaging execution process, the automatic loading device is set to an AGV transport vehicle. In this step, the method of using the AGV transport vehicle is:

[0025] The AGV transport vehicle can immediately transport the waste to the stacking area. With the cooperation of the stacker in the stacking area, several packages can be stacked in the designated stacking area, and different stacking areas can be distinguished according to the material.

[0026] Alternatively, a stacker is arranged at the terminal position area of ​​the lower conveyor line, and a plurality of packages are stacked onto the AGV transport trolley by the stacker, and all loaded packages are transported away when the AGV transport trolley is fully loaded;

[0027] Alternatively, the AGV transport vehicle delivers the packages to the high-bay warehouse for storage.

[0028] Furthermore, the packaging machine involved in the process includes the following parts in sequence:

[0029] Upper transport components;

[0030] The material storage weighing component has an openable and closable hopper and a weighing device. When the hopper is closed, the weighing device weighs the temporarily stored waste. The hopper has a weighing function to monitor the weight of the waste in real time.

[0031] Automatic packaging components for compressing waste into bales of predetermined shapes;

[0032] Discharging coding components;

[0033] The lower conveyor line is connected with the discharging coding component to receive and convey the coding-finished packages;

[0034] The online packaging master control system, the upper transport component, the material storage weighing component, the automatic packaging component, the material discharging coding component and the lower conveying line are all controlled by the online packaging master control system.

[0035] The beneficial effects of the present invention are:

[0036] 1. Intelligent process design not only improves the efficiency and quality of waste treatment, but also reduces the need for manual intervention, reduces errors and losses in the waste treatment process, thus realizing the automation, intelligence and high efficiency of the waste treatment process;

[0037] 2. With the function of classified waste treatment, this process not only realizes the basic waste treatment links, but also integrates a number of advanced functions such as waste classification ability, emptying ability, emergency treatment mechanism, etc., which enables the process system to treat waste in an all-round way, ensures the integrity and accuracy of the treatment process, and greatly improves the quality and comprehensive ability of waste treatment;

[0038] 3. Highly integrated with the production line. The system of this process is closely combined with the stamping production line to achieve a high degree of integration. Through seamless connection with the production line, the system can obtain production status in real time and adjust the processing strategy as needed to ensure a high degree of coordination between the processing and the production line. This highly integrated feature gives the system excellent flexibility and adaptability, further improving the production efficiency of the overall process. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Figure 1 It is a schematic diagram of the hardware arrangement of the present invention.

[0040] Figure 2 It is a schematic diagram of the process flow of the present invention. DETAILED DESCRIPTION

[0041] The following will be combined with the attached embodiment of the present invention Figure 1-2 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In a stamping workshop, there are usually two production lines to meet production capacity: stamping line A and stamping line B. Stamping line A and stamping line B are each equipped with a scrap conveyor chain.

[0043] Based on the implementation method of the packaging strategy, the first step is to collect data from stamping line A and stamping line B. By collecting the number of modules, the number of parts and the amount of waste of a single stamping part for steel parts, 5-series aluminum parts and 6-series aluminum parts, statistical data is performed to confirm whether the waste can meet the automated production conditions of the packaging line; therefore, collecting and analyzing data are key steps in order to select a matching packaging strategy.

[0044] The waste materials involved in the stamping line are divided into four categories: steel, two types of 6 series aluminum, and one type of 5 series aluminum. Different materials cannot be mixed and packaged.

[0045] Value is defined as the added value brought, and the following formula is proposed:

[0046] Value = current batch production quantity ╳ Waste weight ╳ (Aluminum block packaged recycling value - bulk material recycling value). Definition: Value (A) is the added value brought by line A, and Value (B) is the added value brought by line B.

[0047] like Figure 2 As shown in the figure, according to the previous data collection, there are two working conditions: the first working condition is that lines A and B produce different aluminum parts, and the second working condition is that lines A and B produce the same aluminum parts. Ensure that the material of the packaged blocks is uniform and prevent mixed materials; the system parameters can be automatically adjusted according to the waste material to achieve automatic packaging operations for different materials.

[0048] For the first working condition, that is, when lines A and B produce different aluminum parts:

[0049] Judging by the online packaging control system:

[0050] If Value(A)>Value(B), then the aluminum material of line A will be packed online, and the bulk material of line B will be received by car or other transportation equipment;

[0051] If Value(A)≤Value(B), the aluminum material of line B will be packaged online, and the bulk material of line A will be received by car or other transportation equipment.

[0052] For the second working condition, that is, when lines A and B produce the same aluminum parts:

[0053] Considering the processing capacity of a single baler, try to achieve maximum baling of a portion of aluminum blocks by switching the flaps, and the remaining bulk aluminum materials will be picked up by cars.

[0054] Waste(A) is defined as the weight of waste generated by stamping line A, and Waste(B) is defined as the weight of waste generated by stamping line B. The capacity of the packaging equipment, namely Waste (capacity of a single packaging machine), is directly related to the size of the cavity and the rhythm of one stroke of the equipment. The overall comprehensive rhythm is one stroke; the maximum packaging volume of a certain waste is the equipment capacity. If the equipment capacity of the packaging machine is exceeded, the waste in the hopper of the storage weighing component 2 will overflow.

[0055] When Waste(A)+Waste(B)>Waste(capacity of a single baler), the values ​​of Value(A) and Value(B) are calculated, and the line with the heavier weight is baled, while the other line is picked up by car or other transportation equipment. Therefore, when the amount of waste exceeds the capacity of the baling equipment, the system bales the waste of line A and line B separately.

[0056] If Waste(A)+Waste(B)≤Waste(capacity of a single baler), the waste from line A and line B are baled using a set of online balers at the same time, that is, lines A and B share a waste baling line. This ensures that the stamping waste from lines A and B can be transported and baled at the same time, provided that the materials are consistent and the waste volume does not exceed the online baling capacity.

[0057] When stamping line A and line B share a scrap line, the switching status of the scrap line needs to be managed through the online packaging master control system. The specific process is as follows:

[0058] The online packaging control system receives the data parameters (stamping die number and corresponding material) given by the stamping line background, extracts and analyzes these parameters according to the data entered into the database in advance, and determines whether they can be packaged at the same time;

[0059] The online packaging master control system ensures that the waste from line A and line B can be switched and merged for transportation only when the materials are consistent and the amount of waste meets the capacity of the packaging equipment.

[0060] In this embodiment, both the online packaging system and the waste conveying system have a fast switching function to adapt to the ever-changing production plan of the stamping line, the packaging needs of different waste switching, and unexpected situations (such as equipment maintenance, etc.), to ensure the continuity of the entire packaging process. This is the technical core of the online packaging equipment for automobile stamping lines.

[0061] The online packaging of stamping waste is to optimize the waste treatment process, reduce waste treatment time and cost, and ensure the classification of waste of different materials and the maximum economic benefit of recycling. For stable production, the information interaction and control between the online packaging system and the stamping line system and the waste conveying line system are the key to the process.

[0062] like Figure 1 As shown, the baler involved in the above process includes the following parts in sequence:

[0063] The upper transport component 1 may be a chain conveyor or other forms of conveying equipment;

[0064] The material storage weighing component 2 has an openable and closable hopper and a weighing device, which is an existing device. The discharge end of the upper transport component 1 is located directly above the hopper of the material storage weighing component 2. The weighing device is connected to the signal of the online packaging master control system to feedback the real-time weight of the waste. When the hopper is closed, the weighing device weighs the temporarily stored waste. The hopper has a weighing function to monitor the weight of the waste in real time.

[0065] An automatic packing component 3, the packing bin of the automatic packing component 3 is located directly below the hopper of the material storage weighing component 2, the automatic packing component 3 is an existing device (refer to the patent application document with publication number CN116587664A of the applicant), which compresses the waste into a bag of a predetermined shape, and the specific structure is not limited here;

[0066] The discharging coding component 4 is an existing device and is arranged at the outlet of the automatic packaging component 3;

[0067] The lower conveyor line 5 can be a chain conveyor or other forms of conveying equipment. The lower conveyor line 5 is connected with the discharge coding component 4 to receive and convey the coding-finished packages.

[0068] Among them, the above parts are all controlled by the online packaging master control system; in addition to the above components, film wrapping machines (to wrap the bales), electromagnetic palletizers (to palletize the bales) and other components can also be set up, and other equipment can also be added according to project requirements.

[0069] In view of the above part, an optimal packaging execution process is proposed. After real-time data collection, analysis, and generation of packaging strategies, the packaging execution process can be carried out. The process includes the following steps:

[0070] First, the upper transport component 1 receives the waste transported by the waste conveyor chain of line A and / or line B, and then transports the waste to the hopper of the storage weighing component 2 for temporary storage. When the hopper of the storage weighing component 2 is closed, the weighing device weighs the temporarily stored waste, and feeds the weight of the waste back to the online packaging master control system;

[0071] When the waste in the storage weighing component 2 accumulates to the weight set by the program, the hopper will automatically open and release the waste downward, so that the waste enters the packaging bin of the automatic packaging component 3 below. After the automatic packaging program is started, the packaging work begins, and the automatic packaging component 3 is used to compress the waste into a predetermined shape of bales for subsequent stacking and transportation;

[0072] After packaging is completed, the bale is pushed out from the discharge port of the automatic packaging component 3, and the bale enters the discharge chain conveyor of the discharge coding component 4. During transportation, the label code is sprayed on the surface of the bale by the label spraying device of the discharge coding component 4 (the label code can record the material, weight, batch and other information of the bale). Each bale has a different identifiable label so that it can be entered into the system for unified management;

[0073] In the last step, the package is transported to the end point of the lower conveyor line 5 - the loading position through the conveyance of the lower conveyor line 5, and the automatic loading equipment is started. The automatic loading equipment can be an AGV transport trolley (multiple) or other equipment. Based on the control of the online packaging master control system, the AGV transport trolley moves to the end position area of ​​the lower conveyor line 5 for fixed-point material collection and discharge.

[0074] The final step has the following options (including but not limited to the options listed):

[0075] The AGV transport vehicle can immediately transport the waste to the stacking area. With the cooperation of the stacker in the stacking area, several packages can be stacked in the designated stacking area, and different stacking areas can be distinguished according to the material.

[0076] Alternatively, a stacker is arranged at the terminal position area of ​​the lower conveyor line 5, and a plurality of packages are stacked onto the AGV transport trolley by the stacker, and all loaded packages are transported away when the AGV transport trolley is fully loaded;

[0077] Alternatively, the AGV transport vehicle delivers the packages to the high-bay warehouse for storage.

[0078] It is worth mentioning that when the bales are loaded onto the AGV transport vehicle or stacked or put into storage, a special scanning device will scan the label code on the bales for entry into the system. Considering that bales of the same material have the same weight, the weight of the load can be obtained by calculating the number of bales.
