[0035] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0036] In existing multi-process production lines, an intermediate conveying device is usually independently provided between each process to convey the workpiece, and the number of processes corresponds one to one with the number of process equipment. The equipment investment cost of such a production line is relatively high.

[0037] In view of this, if Figure 1 and Figure 2 As shown, the present application provides a multi-process production line, which includes a circulating conveying device 4, a plurality of process equipment and a plurality of loading and unloading devices. The circulating conveying device 4 includes a carrier 47 for cyclically conveying workpieces along a circular conveying route, and the circular conveying route of the circulating conveying device 4 has a plurality of material levels. When the carrier 47 cyclically conveys the workpiece along the circular conveying route, it can circulate through different material levels. A plurality of process equipments are arranged adjacent to a plurality of material levels in a one-to-one correspondence, and a plurality of loading and unloading devices are used to transfer workpieces 9 between the carrier 47 and the process equipment. Among them, at least one process equipment can perform at least two different production process operations.

[0038] It can be seen that since the circulating conveying device has a circular conveying route with several material levels, different material levels are respectively provided with corresponding process equipment, that is, different process equipment can share one circulating conveying device 4 for workpiece transportation. The utilization rate of the circulating conveying device 4 is high, and the number of intermediate conveying devices is reduced, which is beneficial to reducing the investment cost of the equipment.

[0039] In addition, since at least one process equipment can perform operations in at least two different production processes, the circulating conveying device 4 adopts a circular conveyor line circulating conveying layout, and each process equipment is arranged around it, so that a variety of workpieces with different degrees of processing completion can circulate between different material levels for loading and unloading, thereby achieving the completion of multiple processes by the same process equipment, further reducing equipment investment, and is particularly suitable for production lines with low production capacity requirements.

[0040] It will be understood by those skilled in the art that the multi-process production line of the present application may be a steel plate rolling production line, or a rolling, forging or other metal parts processing and forming production line. The type of process equipment can be set according to the specific type of production line. The multi-process production line of the present application may be provided with 1, 2, 3 or even more process equipment capable of performing at least two different production processes, and the process equipment may perform the production of 2, 3 or even more different production processes, and the specific number may be designed according to the actual production conditions. The annular conveying route may be a closed annular shape such as a circle, an ellipse, a rounded rectangle, a rounded triangle or other irregular shapes.

[0041] In addition, the structures of the circulating conveyor 4 and the carrier 47 can be various, for example, a tray, a hanging hanger or other structures, and the structure of the carrier 47 can be set accordingly according to the conveying form of the circulating conveyor 4. The conveying form of the circulating conveyor 4 can be an endless chain, an endless roller, an endless track trolley or other forms. The loading and unloading device can be a robot, a reciprocating machine or other automatic mechanism, and the structures of several loading and unloading devices can also be the same or different.

[0042] In addition, if there are multiple carriers 47, the circulating conveying device 4 can not only perform the transfer and conveying functions between processes, but also serve as an intermediate buffer, which can buffer the rhythm imbalance between the processes to a certain extent, improve the overall efficiency of the production line, and improve the flexibility of the production line.

[0043] In some specific embodiments, Figure 2 As shown, the circulating conveying device 4 also includes an annular traction chain 45 and a driving mechanism 41. The annular traction chain 45 is connected to the carrier 47 and is used to drive the carrier 47 to move on the annular conveying route. The driving mechanism 41 is drivingly connected to the annular traction chain 45 and is used to drive the annular traction chain 45 to operate.

[0044] In some specific embodiments, since the medium and thick plate workpiece is heavy, the circulating conveying device 4 may further include a supporting assembly and a travel wheel 46. Figure 2 As shown, the annular traction chain 45 is movably arranged on the support assembly, and the walking wheel 46 is arranged at the bottom of the carrier 47 and can walk on the support assembly. In this way, the load-bearing capacity of the carrier 47 can be improved, making the structure of the circulating conveying device 4 more stable and reliable.

[0045] Alternatively, if Figure 2 As shown, the support assembly may include a support platform 43 and a plurality of support columns 42 connected to the lower portion of the support platform 43. When the carrier 47 moves along the circular conveying route driven by the circular traction chain 45, the running wheels 46 arranged at the bottom of the carrier 47 run on the support platform 43. The support platform 43 is also provided with a circular guide rail 44, and the circular traction chain 45 is arranged in the circular guide rail 44.

[0046] Alternatively, if Figure 1 As shown, the material level may include a material unloading position, the process equipment includes a finished product loading device 8 arranged adjacent to the material unloading position, the upper and lower pieces device includes a third upper and lower pieces device 7, the finished product loading device 8 is used to store the rolled finished products, and the rolled finished products can be transferred to the finished product loading device 8 through the third upper and lower pieces device 7 for unloading.

[0047] In some specific embodiments, a position sensor is provided at each material level, and the multi-process production line also includes a controller, which is respectively communicated with the position sensor and the circulating conveying device 4, the process equipment and the loading and unloading device, and is used to control the operation of the process equipment, the loading and unloading device and the circulating conveying device 4.

[0048] When the carrier 47 approaches the material level, the corresponding position sensor reports the position information to the controller. The controller determines whether the circulating conveyor device 4 stops according to the product production process and the operation logic of the production line and instructs the corresponding loading and unloading device whether to perform loading and unloading operations. At the same time, the loading and unloading device feeds back all loading and unloading operations of the carrier 47 in real time and uploads them to the controller, that is, the controller knows the loading information of each carrier 47 at any time (including whether it is loaded and the information of the loaded workpieces, etc.), and interacts with each material level in real time. In this way, the carrier 47 can achieve precise control of the entire process and the entire system.

[0049] Optionally, the controller may include a central control machine (central control computer) and supporting software, etc., which may be arranged beside the circulating conveying device 4, or a special central control room may be arranged.

[0050] In some specific embodiments, Figure 1As shown, a multi-process production line can be used for rolling steel plates, the material positions include a rolling and rounding position and a welding position, and the process equipment includes a rolling machine 2 and a welding machine 6. The rolling machine 2 is arranged adjacent to the rolling and rounding position and is used to roll the steel plate raw material into a rolled round billet or round the welding billet into a rolled finished product. The welding machine 6 is arranged adjacent to the welding position and is used to weld the rolled billet into a welded billet. The upper and lower parts device also includes a first upper and lower parts device 3 and a second upper and lower parts device 5, the first upper and lower parts device 3 is arranged between the rolling and rounding position and the rolling machine 2, and the second upper and lower parts device 5 is arranged between the welding position and the welding machine 6.

[0051] Among them, the production process of steel plate rolling can be as follows: the steel plate raw material is rolled into a rolled billet by the rolling machine 2, and then transferred to the circulating conveying device 4 through the first upper and lower parts device 3. The circulating conveying device 4 is running, and the rolled billet is transported to the welding position, and the second upper and lower parts device 5 takes the billet for welding. After welding into a welding billet, it is put back into the circulating conveying device 4 by the second upper and lower parts device 5, and then transported back to the rounding calibration position by the circulating conveying device 4. The first upper and lower parts device 3 takes the billet, and after rounding into a finished rolled product by the rolling machine 2, it is unloaded to the circulating conveying device 4. The circulating conveying device 4 continues to operate, and the workpiece is transferred to the unloading position, and the third upper and lower parts device 7 takes the billet and loads it on the pallet. When passing the welding position, the controller determines that the process is directly skipped, and welding will not be repeated. That is, there are workpieces in three states of rolled billets, welding billets and rolled finished products on the circulating conveying device 4 at the same time, which are uniformly identified and controlled by the controller to ensure the efficient and orderly operation of each process.

[0052] Alternatively, if Figure 1 As shown, the multi-process production line may further include a loading device 1 , which is disposed adjacent to the rolling machine 2 and is used to transfer the steel plate raw material to the rolling machine 2 .

[0053] Optionally, the specific operation method of the multi-process production line of the present application may include:

[0054] 1. After the steel plate raw material is sent to the rolling machine 2 by the feeding device 1 and rolled (and spot welded), it is pushed out of the rolling station of the rolling machine 2. It is transferred to the carrier 47 of the circulating conveying device 4 by the first loading and unloading device 3;

[0055] 2. The controller controls the circulation conveying device 4 to operate and convey the workpiece to the welding position;

[0056] 3. The second loading and unloading device 5 takes the workpiece from the circulating conveying device 4, and after the welding operation is completed, the second loading and unloading device 5 puts the workpiece back into the empty carrier 47 of the circulating conveying device 4 (during welding, the circulating conveying device 4 can keep running under the control of the controller as needed, without waiting);

[0057] 4. The circulating conveying device 4 continues to operate, and rotates the welded workpiece to the rounding and rounding position. The first loading and unloading device 3 takes the workpiece from the circulating conveying device 4 and sends it to the rounding machine 2 for rounding (at this time, the controller controls the steel plate raw material feeding and rounding operation to be suspended). After the rounding is completed, the first loading and unloading device 3 puts the workpiece back to the circulating conveying device 4;

[0058] 5. The circulating conveying device 4 continues to operate and delivers the rounded finished product after rounding to the unloading position (when the workpiece passes the welding position again, the controller recognizes it and skips this process);

[0059] 6. After the rounding machine 2 completes the rounding work, it will perform the rounding work again according to the judgment of the controller and enter the next cycle.

[0060] It should be noted that the structures of the feeding device 1, the rolling machine 2, the loading and unloading devices, the welding machine 6 and the finished product loading device 8 are well known to those skilled in the art and do not belong to the core improvement part of the present application, so they will not be repeated here.

[0061] In summary, the equipment of each process of the multi-process production line of the present application is arranged around the circulating conveyor device, which effectively connects each process. The operation of two processes can be completed by the same process equipment, thereby reducing equipment investment, which is particularly suitable for production lines with low production capacity requirements. Moreover, the circulating conveyor device can not only undertake the transfer and transportation functions between processes, but also serve as an intermediate cache, which is a multifunctional conveying buffer device. In addition, the circulating conveyor device can be provided with multiple carriers, which run reciprocatingly. When the rhythm of a certain workstation is slow, there is no need to wait, and the process can be temporarily skipped (the operation of the process can be completed after the circulating conveyor comes back), and the process can continue to be transported to the next workstation to avoid waiting for the next process. In addition, through reasonable scheduling and control by the controller, the rhythm of each process can be balanced to a certain extent, the overall efficiency can be improved, and the production line is more flexible.
