[0002] This invention claims priority to Chinese Patent Application No. 202411178051.3, filed with the China National Intellectual Property Administration on August 27, 2024, entitled "An Automatic Packing System and Packing Method at the End of a Stamping Line", the entire contents of which are incorporated herein by reference and constitute a part of this invention for all purposes. Technical Field

[0003] This invention relates to the field of automated production technology, and in particular to an automatic boxing system and boxing method at the end of a stamping line. Background Technology

[0004] Currently, most automotive stamping lines have been equipped with robots / robotic arms to replace manual labor, forming automated stamping production lines, which greatly improves production efficiency and reduces labor costs. However, at the end of the current automated stamping production line, most parts are still manually stacked and boxed, or only large parts such as side panels are automated. To address the gap in the automation of the end of the stamping production line, an automatic boxing system for the end of the stamping automated production line has been proposed in existing technologies.

[0005] The existing automated packing system is shown in Figure 1. On the entire production line, the main material flow direction is from top to bottom. The quality inspection conveyor belt and the packing conveyor belt are arranged sequentially along this direction. Packing robots are positioned on both sides of the packing conveyor belt, picking up products from the conveyor belt and placing them onto the unloading basket. However, this type of automated packing system requires a significant amount of space along the material flow direction, making it unsuitable for some on-site conditions with limited space. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic packing system at the end of a stamping line, thereby solving the problem that existing automatic packing systems occupy a large amount of space in the logistics direction and cannot adapt to certain on-site layouts.

The belt conveyor is located at the end of the stamping line and includes a quality inspection belt conveyor and a boxing belt conveyor arranged sequentially. The quality inspection belt conveyor is arranged perpendicular to the main material flow direction of the stamping line. The boxing belt conveyor and the quality inspection belt conveyor are two independent belt conveyors arranged on the same line, or the boxing belt conveyor and the quality inspection belt conveyor are two sections on the same belt conveyor. The boxing robot is located on one side of the boxing belt conveyor along the main material flow direction, and the basket conveyor is located on the side of the boxing robot away from the boxing belt conveyor.

[0009] Optionally, the packing system is provided in two sets at the end of the stamping line. The two packing systems are located on both sides of the stamping line perpendicular to the main logistics direction, and the two packing systems are arranged symmetrically relative to the main logistics direction.

[0010] Optionally, the automated packing system also includes a sorting robot, which is located at the end of the stamping line and is used to transfer products from the stamping line to the quality inspection conveyor belt.

[0011] Optionally, the material basket conveying device includes multiple conveying stations that form a closed loop path. The multiple conveying stations include a box-packing station, a loading / unloading basket station, and a regular conveying station. The box-packing station is located at the box-packing robot position, the loading / unloading basket station is located diagonally opposite the box-packing station, and the regular conveying station connects the box-packing station and the loading / unloading basket station in series.

[0012] Optionally, a transition platform is provided between the material basket conveying device and the boxing belt conveyor. The transition platform is used to place the products conveyed by the boxing belt conveyor during the material basket replacement process at the boxing position.

[0013] Optionally, the material basket conveying device is provided with a base, conveying rollers, conveying chain and lifting frame. The conveying rollers and conveying chain are both installed on the base. The conveying rollers and conveying chain are arranged alternately in parallel and the conveying directions of the conveying rollers and conveying chain are perpendicular. The bottom of the conveying roller is provided with a lifting frame, which can drive the conveying roller to rise and fall above or below the conveying chain.

[0014] Optionally, the automatic packing system also includes a pallet, and the basket conveying device is further provided with a limit and pallet guide rail, which is arranged on the outer contour of the top of the basket conveying device, and the pallet moves along the limit and pallet guide rail.

[0015] Optionally, the material basket conveying device further includes a forklift stop, which is disposed on the side of the opening of the upper and lower material basket positions.

[0016] Optionally, the automatic packing system also includes a visual positioning system, which is located on the upper side of the packing conveyor belt.

[0017] This invention also provides a packing method for an automatic packing system at the end of a stamping line as described above, comprising: moving a material basket between various stations of a material basket conveying device; moving a full material basket at a packing station to the next station, while simultaneously moving an empty material basket from the previous station to the packing station; when a material basket is replaced at a packing station, a packing robot places a product removed from the packing conveyor onto a transition table, which is recorded as a temporary storage product; then, the packing robot sequentially transports products from the packing conveyor to empty material baskets at the packing station; when the material basket is about to be full, the packing robot transports the temporary storage product from the transition table into the material basket, filling the material basket, and then moving the material basket to the next station.

[0018] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0019] 1.

It makes full use of the space perpendicular to the main logistics direction of the production line, solves the problem of limited space in the planar logistics direction while meeting the production cycle, reduces the space occupied in the main logistics direction, and realizes the project layout under the condition of limited space in the main logistics direction of the production line.

[0020] 2. The packing system has a transition platform between the basket conveyor and the packing belt. When changing baskets at the packing position, the product is temporarily placed on the transition platform and the temporarily stored product is loaded into the last basket. Since the distance from the transition platform to the basket and the packing belt is relatively short, the packing efficiency is improved by setting up the transition platform and coordinating the order of loading the temporarily stored products, thus making reasonable use of the production cycle.

[0031] Example 1

[0032] As described in the background section, a packing system requires more space in the main logistics direction of the production line to achieve the same function. If the space in the logistics direction of the project site is limited, the packing system cannot be implemented.

[0033] To address the aforementioned technical problems, one embodiment of the present invention proposes an automatic boxing system at the end of a stamping line, as shown in Figure 2. The system includes a belt conveyor, a boxing robot 3, and a basket conveyor 5. The belt conveyor is located at the end of the stamping line and includes a quality inspection belt conveyor 1 and a boxing belt conveyor 2 arranged sequentially. The quality inspection belt conveyor 1 is arranged perpendicular to the main material flow direction of the stamping line. The boxing belt conveyor 2 and the quality inspection belt conveyor 1 are two independent belt conveyors arranged colinearly, or they can be two sections of the same belt conveyor. The boxing robot 3 is located on one side of the boxing belt conveyor 2 along the main material flow direction, and the basket conveyor 5 is located on the side of the boxing robot 3 away from the boxing belt conveyor 2.

[0034] This packing system adjusts the existing process layout and changes the product discharge direction, making the quality inspection conveyor belt 1 and the packing conveyor belt 2 perpendicular to the main logistics direction. It makes full use of the space perpendicular to the main logistics direction of the production line, solves the problem of limited space in the planar logistics direction while meeting the production cycle, reduces the space occupied in the main logistics direction, and enables the project to be arranged under the condition of limited space in the main logistics direction of the production line.

[0035] The packing system is set in two sets at the end of the stamping line. The two packing systems are located on both sides of the stamping line perpendicular to the main logistics direction, and the two packing systems are symmetrically arranged relative to the main logistics direction. As shown in Figure 2, the main logistics direction of the product stamping line is from top to bottom. A packing system is set on each of the left and right sides at the end of the stamping line. The product is packed after leaving the line through the two symmetrically arranged packing systems.

[0036] The automated packing system also includes a diversion robot 4, which is located at the end of the stamping line, as shown in Figure 2. The diversion robot 4 is used to transfer products from the stamping line to the quality inspection conveyor belt 1. The main function of the diversion robot 4 is to transfer the products from the stamping line to the two quality inspection conveyor belts 1, while adjusting the product placement angle to 90 degrees. This changes the traditional method of feeding materials along the main material flow direction to diversion feeding perpendicular to the material flow direction. Furthermore, to adapt to the limited space, only one material basket conveyor device 5 is installed on each side, thus greatly reducing the space required by the system.

[0037] The material basket conveying device 5 includes multiple conveying stations that form a closed loop path. The multiple conveying stations include a box-packing station 51, a loading and unloading basket station 52, and a regular conveying station. The box-packing station 51 is located at the position of the box-packing robot 3. The loading and unloading basket station 52 is located diagonally opposite the box-packing station 51. The regular conveying station connects the box-packing station 51 and the loading and unloading basket station 52 in series.

[0038] As shown in Figure 3, in this embodiment, the basket conveying device 5 consists of four basket stations: a lower left station, an upper left station, an upper right station, and a lower right station. The lower left station is the basket loading / unloading station 52, where baskets are loaded and unloaded in conjunction with a forklift or AGV. The upper right station is the boxing station 51, where baskets are boxed. Empty baskets are loaded onto the basket conveying device 5 from the basket loading / unloading station 52, then move sequentially to the upper left station and the upper right station, where they are boxed. The baskets then move sequentially to the lower right station and the lower left station, and finally, in conjunction with a forklift or AGV, the baskets are unloaded, completing one cycle.

[0039] In existing packing systems, material baskets are arranged in a straight line, and the packing robot 3 is positioned on guide rails, moving along the guide rails to complete the filling of each basket. In this embodiment, with the addition of the material basket conveying device 5, there is no need to set up guide rails for the packing robot 3 to move; the packing robot 3 can be directly fixed in place, which facilitates packing and makes positioning control easier. Moreover, since the actual space on site perpendicular to the logistics direction is not infinitely large, this method maximizes the saving of space in the logistics direction based on the workshop width (i.e., perpendicular to the main material direction).

[0040] As shown in Figure 2, a transition platform 6 is provided between the material basket conveying device 5 and the boxing belt conveyor 2. The transition platform 6 is used to place the products conveyed by the boxing belt conveyor 2 during the material basket replacement process on the boxing position 51. By setting the transition platform 6 and coordinating the product boxing sequence, the production cycle is rationally utilized, and the boxing efficiency is improved.

[0041] As shown in Figures 4, 5, and 6, the material basket conveying device 5 is equipped with a base 510, a conveying roller 53, a conveying chain 54, and a lifting frame 58. The conveying roller 53 and the conveying chain 54 are both mounted on the base 510, arranged alternately in parallel, and their conveying directions are perpendicular. A lifting frame 58 is also provided at the bottom of the conveying roller 53. The lifting frame 58 is driven to rise and fall by a cylinder or airbag, which in turn drives the conveying roller 53 to rise or fall above or below the conveying chain 54. As shown in Figure 4, both the conveying roller 53 and the conveying chain 54 are arranged laterally. When the conveying roller 53 is higher than the conveying chain 54, the conveying roller 53 moves the material basket vertically; when the conveying roller 53 is lower than the conveying chain 54, the conveying chain 54 moves the material basket horizontally. The conveyor roller 53 and the conveyor chain 54 carry the material baskets. The conveyor roller 53 is driven to rotate by the first drive mechanism 56 (roller conveyor reducer), and the conveyor chain 54 is driven to rotate by the second drive mechanism 57 (chain conveyor reducer). The power system completes the conversion between empty and full material baskets between the four workstations, so that empty material baskets can enter the boxing position 51 and full material baskets in the boxing position 51 can come out. At the same time, it cooperates with forklifts or AGVs to realize the loading and unloading of material baskets.

[0042] The automatic packing system also includes a pallet, and the basket conveying device 5 is further equipped with a limit and pallet guide rail 55. The limit and pallet guide rail 55 is arranged on the outer contour of the top of the basket conveying device 5, and the pallet moves along the limit and pallet guide rail 55. During transportation, the baskets are placed on the pallet, and the movement of the pallet at each station drives the transportation of the baskets, solving the problem of the original baskets being of different sizes and shapes and difficult to control.

[0043] As shown in Figure 5, the material basket conveying device 5 also includes a forklift stop 59, which is located on the side of the opening of the upper and lower material basket positions 52. The forklift stop 59 facilitates loading and unloading of material baskets with a forklift.

[0044] The packing conveyor belt 2 can adopt existing technology, consisting of two servo synchronous belts and their position adjustment mechanisms on each side. Its main function is to adjust the two servo synchronous belts through the position adjustment mechanism to adapt to the needs of various products and accurately transport the products exiting the line to the material handling station of the packing robot 3.

[0045] The packing robot 3 is mounted on the robot base 510. The main function of the packing robot 3 is to accurately locate the current product using the position information provided by the camera and then transport the product conveyed by the servo synchronous belt to the storage container (basket).

[0046] The automated packing system also includes a vision positioning system, which is located on the upper side of the packing conveyor belt 2. The vision positioning system consists of a camera system and several vision-aided lighting systems. The main function of the camera system is to photograph the product as it is conveyed on the servo-synchronous belt and compare the photograph with the product's position during trial production to calculate the current deviation position of the product, which is then transmitted to the PLC controller and robot controller. The main function of the vision-aided lighting system is to assist the camera in adapting to different weather conditions and lighting conditions, meeting the camera's exposure requirements for taking pictures.

[0047] The automated packing system also includes an ATC (Automatic End Capture Changer), an electrical control system, and a pneumatic system. The main function of the ATC is to allow manual installation of the end caps required for the next batch of products onto the common end cap tray on the ATC while the production line is in operation. During the ADC (Automatic Tool Changer) process on the production line, the packing robot 3 works in conjunction with the ATC to automatically change the end caps between the old and new batches of products, significantly reducing the time required for manual end cap changes during the ADC process and meeting the overall ADC time requirements.

[0048] ATC can be selected from rotary or fixed types according to actual working conditions and space requirements. The rotary ATC mainly consists of a fixed frame, a rotating frame, an end effector station, and a power mechanism. Two end effector stations are symmetrically arranged on the rotating frame, corresponding to the positions of the old and new batches of end effectors respectively. Each time the end effector is automatically changed, the robot places the end effector of the old batch of products into the empty end effector station, and then the ATC rotates 180°. The robot then picks up the end effector of the next batch of products that has been prepared on the other end effector station and fits it onto the robot arm, thus completing the entire ATC action. Fixed ATCs are used in pairs. Each ATC has one end effector station. A pair of ATCs has two end effector stations, corresponding to the end effector positions of the old and new batches respectively. Each time the end effector is automatically changed, the robot places the end effector of the old batch of products into the end effector station of one ATC. Then the robot picks up the end effector of the next batch of products that has been prepared in the end effector station of the other ATC and adapts it to the robot arm, thus completing the entire ATC action.

[0049] The end effector is installed at the end of the robot arm during use. Each robot end effector mainly consists of several end effector support rods, quick-connect couplings, suction cups, and air hoses. Its main function is to adjust the position of the suction cup according to the shape of various products, and to use a vacuum system to provide power to pick up the products for robot handling.

[0050] The electrical control system mainly consists of a PLC system, several remote I / O substations, servo drives, a touch screen, and other electrical modules. Its main function is to coordinate the control of all components.

[0051] The pneumatic system mainly consists of a vacuum device, solenoid valve, cylinder, air pipe, connector, suction cup, etc. Its main functions are to provide negative pressure so that the end effector can pick up the product (the end effector is a suction cup) and to provide positive pressure to generate the action source for devices such as ATC (the end effector is a cylinder).

[0052] Example 2

[0053] Based on the automatic packing system of Embodiment 1, this embodiment proposes a packing method. The packing conveyor 2 places products onto two quality inspection conveyors 1, one on the left and one on the right. The subsequent processes on both quality inspection conveyors 1 are identical. Taking the right side as an example, products flow from quality inspection conveyor 1 to packing conveyor 2. A vision positioning system installed above packing conveyor 2 takes photos for positioning. The vision positioning system compares the photos of each product with the product position during trial production to obtain the positional deviation information for each product. This positional deviation information is transmitted to the PLC controller and robot controller. The robot automatically adjusts its gripping based on this positional deviation information and places the products into the baskets on the basket conveyor 5. The basket conveyor 5, in conjunction with a forklift or AGV, moves empty baskets to the packing position 51 and unloads full baskets from the packing position 51. Furthermore, an end effector changing device (ATC) is correspondingly arranged on the second-level platform above the packing robot 3, enabling automatic replacement of the end effector for the current product with the end effector for the next product.

[0054] The products move sequentially along the stamping line, the quality inspection conveyor belt 1, and the packing conveyor belt 2, changing direction as they move from the stamping line to the quality inspection conveyor belt 1. The packing robot 3 sequentially transports the products from the packing conveyor belt 2 to the material baskets at the packing station 51. The material baskets move between the various stations of the material basket conveyor device 5. When the material basket at the packing station 51 is full, it moves to the next station, while the empty material baskets at the previous station move to the packing station 51.

[0055] When changing the material basket at the packing station 51, the packing robot 3 places the product taken from the packing conveyor 2 onto the transition table 6, and this product is recorded as a temporary storage product. Then, the packing robot 3 sequentially transports the products from the packing conveyor 2 to the empty material baskets at the packing station 51. When the material basket is about to be full, the packing robot 3 transports the temporary storage product from the transition table 6 into the material basket, filling the material basket (i.e., the temporary storage product is the last one to be loaded into the material basket), and the material basket moves to the next station. The above process is repeated in sequence.

[0056] In the conventional packing process, the packing robot 3 sequentially loads the products into the material baskets. When the material baskets are changed, the packing conveyor belt 2 and the packing robot 3 are paused. Even if a transition platform 6 is set up, the temporarily stored products are first loaded into the material baskets, or the temporarily stored products are loaded into the material baskets during the packing process.

[0057] In this embodiment, a transition platform 6 is set between the material basket conveying device 5 and the boxing belt conveyor 2. When changing the material basket at the boxing position 51, the product is temporarily placed on the transition platform 6 and the temporarily stored product is loaded into the last material basket. Since the distance between the transition platform 6 and the material basket and the boxing belt conveyor 2 is relatively short, the setting of the transition platform 6 and the coordination of the loading sequence of the temporarily stored product achieve uninterrupted product handling when changing the material basket at the boxing position 51, reducing the production interruption time caused by changing the material basket, making reasonable use of the production cycle, and improving the boxing efficiency.

[0058] Comparative analysis of different crate loading methods:

[0059] Comparison conditions (refer to Figure 7):

[0060] ① The allowed replacement time is from the moment the robot leaves the packing position 51 after the last part of the previous basket has been loaded until the robot of the next basket arrives at the packing position 51 to load the first part.

[0061] ② Assuming the loading cycle time for each part is 8 seconds, let's take the time from when the robot leaves the loading position 51 after loading the second-to-last part of the previous basket until the robot of the next basket arrives at the loading position 51 to load the first part (the time for robot to grab and place parts is not considered for the time being, only the intermediate trajectory time is calculated). Let's denote this time period as P, and the round-trip time for loading the last part as A. Then, the allowable replacement time is PA.

[0062] ③ Since the transition table 6 is located between the gripping position and the packing position 51, the one-way time from the transition table 6 to the packing position 51 is shorter than the one-way time from the gripping position to the packing position 51. Assume that the one-way time from the transition table 6 to the packing position 51 is 2s and the one-way time from the gripping position to the packing position 51 is 4s.

[0063] The allowable replacement time under different modes are as follows:

[0064] Mode ① (i.e., this embodiment): The parts on the transition table 6 are placed at the last position of each batch of baskets. The second to last part of the previous basket and the first part of the next basket are both moved from the pick-up position to the packing position 51, so P = 8 × 2 = 16s. The last part is moved from the transition table 6 to the packing position 51, so A = 2 × 2 = 4s. Therefore, the allowable changeover time is PA = 16 - 4 = 12s.

[0065] Mode ②: No transition platform 6 is set. The second to last part of the previous basket and the first part of the next basket are both from the pick-up position to the packing position 51, so P = 8 × 2 = 16s. The last part is from the pick-up position to the packing position 51, so A = 4 × 2 = 8s. Therefore, the allowable changeover time is PA = 16 - 8 = 8s.

[0066] Mode 3: The parts on the transition table 6 are placed at the first position in each batch of baskets. The second to last part of the previous basket is moved from the pick-up position to the packing position 51, and the first part of the next basket is moved from the transition table 6 to the packing position 51. Therefore, P = 8 + 2 × 2 = 12s. The last part is moved from the pick-up position to the packing position 51. Therefore, A = 4 × 2 = 8s. Thus, the allowable changeover time is PA = 12 - 8 = 4s.

[0067] Mode 4: The parts on the transition table 6 are placed in the middle of each basket (meaning the movement of the transition table 6 does not involve the movement of the second-to-last part to the first part of the next cycle). The second-to-last part of the previous basket and the first part of the next basket both move from the pick-up position to the packing position 51, so P = 8 × 2 = 16s. The last part is moved from the pick-up position to the packing position 51, so A = 4 × 2 = 8s. Therefore, the allowable changeover time is PA = 16 - 8 = 8s.

[0068] In summary, placing the parts on the transition table 6 at the end of each material basket allows for the longest possible replacement time.

[0069] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.

When the material basket is about to be full, the packing robot transports the temporary storage products from the transition table into the material basket, fills the material basket, and then moves the material basket to the next station.
