An automated shoe box production line

Abstract

This invention discloses an automated shoebox production line. A first robotic arm drives a picking component to grasp a hollow base and place it on a support conveyor line. Then, it grasps a receiving box, placing the positioning components on both sides of its outer wall facing each other on a support. The first robotic arm then drives the picking component to move the receiving box horizontally along the support, allowing the positioning components to enter a guide and limiting space. Finally, the picking component stops grasping the receiving box, and the positioning components move along the guide and limiting space, completing the automatic assembly of the receiving box and the hollow base. The assembled shoebox is then conveyed to a bagging mechanism via the support conveyor line for bagging. A second robotic arm drives a clamping structure to initially adhere and fix the bagged shoebox with suction cups. The first and second clamping units are then adjusted to clamp and fix the four sides of the shoebox, thus achieving stable fixation. The entire production line requires no manual labor, saving manpower and improving production efficiency.

Description

Technical Field

[0001] This invention relates to the field of automated shoe box production line technology, and in particular to an automated shoe box production line. Background Technology

[0002] Shoe boxes are a common household item. Placing shoes in shoe boxes makes them easier to categorize and manage.

[0003] Currently, there is a type of shoe box, which includes a hollow base 7 and a container 6 that are injection molded. After the hollow base 7 and the container 6 are injection molded separately, they need to be assembled into a complete shoe box. After that, a second transfer is required for bagging and unloading after bagging.

[0004] Currently, the hollow base 7 and the receiving box 6 are assembled manually. The injection-molded hollow base 7 and receiving box 6 need to be collected separately and transported to a designated location far from the injection molding machine for safe manual assembly. Furthermore, the hollow base 7 and receiving box 6 must be allowed to cool down before assembly to avoid burns to the hands from manually assembling the freshly injection-molded material. This method is not only inefficient and labor-intensive but also potentially harmful. After the shoebox is assembled, it needs to be transferred to a bagging mechanism for bagging before finally unloading. Due to the presence of the outer packaging bag, if suction cups are used for unloading, there is a risk of the shoebox falling off during the unloading and transport process due to unstable suction. If the outer packaging bag is torn, multiple clamping components can be used to clamp and fix the shoe box on all six sides to ensure that the shoe box does not shift during the unloading process, thus ensuring accurate unloading. However, when the shoe box is placed in the designated position for unloading, since the gripper of the bottommost clamping component is in contact with the ground or the supporting surface of the shoe box's storage component, a driving structure is also required to drive the bottommost gripper to detach from the bottom of the shoe box to ensure stable placement. However, adding an additional driving structure will increase costs, and the action of driving the bottommost gripper to detach from the bottom of the shoe box will prolong the unloading time and reduce the unloading speed. Therefore, the overall shoe box production process is not only labor-intensive and poses certain safety hazards, but also has low production efficiency. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides an automated shoe box production line to solve the problems that the current shoe box production process is not only labor-intensive and has certain safety hazards, but also has low production efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an automatic shoe box production line, wherein the shoe box is prismatic in shape, including a hollow base and a receiving box, the hollow base has an opening at the top, the receiving box has an opening on one side, and at least one positioning element is provided on both outer walls of the opening of the receiving box. Support portions and at least two limiting portions are provided on both sides of the inner wall of the hollow base, and the two limiting portions form a guiding and limiting space. The automatic production line includes: A support conveyor line is used to support and place the hollow base, and to transport the assembled shoe boxes through a bagging mechanism for bagging. The assembly mechanism includes a first robotic arm and a material-grabbing component located at the output end of the first robotic arm. The first robotic arm is used to drive the material-grabbing component to move and grab the hollow base and place it on the support conveyor line. Then, it grabs the receiving box and moves the positioning component to the support part. After that, it moves along the surface of the support part into the guide limiting space so that the receiving box and the hollow base are fastened together and assembled. A bagging mechanism for fitting at least one assembled shoebox into a bag; The unloading mechanism is used to unload bagged shoe boxes on the support conveyor line. The unloading mechanism includes a second robotic arm and a clamping structure located at the output end of the second robotic arm. The clamping structure includes a first clamping unit, a second clamping unit, and several suction cups. The first clamping unit is used to clamp and fix two sides of the bagged shoe box, the second clamping unit is used to clamp and fix the other two sides of the bagged shoe box, and the suction cups are used to adsorb and fix one side of the bagged shoe box.

[0007] Preferably, the automated production line further includes a first injection molding machine for injection molding hollow bases and a second injection molding machine for injection molding housings. The assembly mechanism is located between the first and second injection molding machines. The support conveyor line includes a first conveyor line, a third conveyor line, a fourth conveyor line, a fifth conveyor line, and a second conveyor line arranged in an S-shape. The second injection molding machine is located between the first and fourth conveyor lines. The bagging mechanism is located between the second injection molding machine and the second conveyor line. The fourth conveyor line passes through the bagging mechanism.

[0008] Preferably, a first blocking part and a second blocking part are respectively provided on the adjacent sides of the first conveyor line, and a first pressing mechanism is also provided on one side of the first conveyor line. The first pressing mechanism is used to press against the hollow base so that the outer wall of the hollow base abuts against both the first blocking part and the second blocking part.

[0009] Preferably, a fixing mechanism is symmetrically provided on both sides of the periphery of the first conveyor line. The fixing mechanism includes a second driving member and a fixing member. When the hollow base is located on the first conveyor line, the two second driving members drive the two fixing members to move closer to each other to clamp and fix the hollow base.

[0010] Preferably, the automated production line further includes a support frame for supporting and placing the container, and the support frame is provided with a positioning fixture for positioning and placing the container.

[0011] Preferably, the positioning fixture includes four positioning blocks, at least one of the positioning blocks having a first abutting surface and a second abutting surface. The automatic production line further includes a second pressing mechanism and a third pressing mechanism. The second pressing mechanism is used to press the receiving box so that one side abuts against the first abutting surface, and the third pressing mechanism is used to press the receiving box so that the other side abuts against the second abutting surface.

[0012] Preferably, the automated production line further includes a first transfer mechanism for transferring shoe boxes from the first conveyor line to the third conveyor line and a second transfer mechanism for transferring them from the third conveyor line to the fourth conveyor line.

[0013] Preferably, both the first and fourth conveyor lines include a support frame and two synchronous conveyor belts spaced apart on the support frame.

[0014] Preferably, the support frame of the fourth conveyor line is also provided with a steering synchronous conveyor belt that is horizontal and perpendicular to the conveying direction of the fourth conveyor line.

[0015] Preferably, the output end of the second robotic arm is fixedly mounted with a support plate, the support plate is provided with a clamping structure and a first baffle, the second conveyor line includes a support frame and two synchronous conveyor belts with a gap in the middle on the support frame, and at least one blocking mechanism is provided on the second conveyor line, the first baffle and the blocking mechanism limit the two ends of the shoe box on the second conveyor line.

[0016] Compared with the prior art, the beneficial effects that this invention can achieve are: The first robotic arm drives the picking component to grasp the hollow base and place it on the support conveyor line. It then grasps the receiving box, aligning the positioning pieces on both sides of its outer wall with the support. The first robotic arm then drives the picking component to move the receiving box horizontally along the support, causing the positioning pieces to enter the guide limiting space. Finally, the picking component stops grasping the receiving box, and the positioning pieces move along the guide limiting space, allowing the receiving box and hollow base to automatically snap together. Afterward, at least one assembled shoebox is conveyed to the bagging mechanism via the support conveyor line for bagging and packaging. The second robotic arm drives the clamping structure to initially adhere and fix the bagged shoebox with suction cups. Then, the first and second clamping units are adjusted to clamp and fix the shoebox to its four sides, thus achieving stable fixation. This design avoids the risk of unstable adhesion leading to shoe boxes falling off or tearing the outer packaging when using suction cups alone for fixation. Furthermore, when the second robotic arm drives the clamping structure for unloading, the bottom of the shoe box can directly contact the ground or the support surface of the storage components supporting the shoe box. This eliminates the need for a separate drive structure to detach the bottom gripper from the bottom of the shoe box during unloading, which is cumbersome in existing systems that clamp all six sides of the shoe box. This design saves on the cost of additional drive structures and eliminates the need for the bottom gripper to detach from the bottom of the shoe box, reducing unloading time and improving efficiency. This results in rapid, automated shoe box production, eliminating the need for manual labor, significantly saving manpower, preventing injuries, and increasing overall production efficiency.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this invention.

[0019] like Figures 5-10 As shown, this invention provides an automated shoe box production line. The shoe box is prismatic in shape and includes a hollow base 7 and a receiving box 6. The hollow base 7 has an opening at the top, and the receiving box 6 has an opening on one side. At least one positioning element 61 is provided on each of the outer walls of the openings of the receiving box 6 (here, two positioning elements 61 are provided on each of the outer walls as an example, and the line connecting the two positioning elements 61 forms an acute angle with the top surface of the receiving box 6, thus facilitating the receiving box 6 to be positioned as shown when the positioning elements 61 are on the support 72). Figure 8 The tilted position shown makes it convenient for people to place shoes into the storage box 6). like Figures 1-10 As shown, to facilitate the quick alignment and placement of the positioning component 61 onto the support 72, inner edges are provided on both sides of the hollow base 7. A notch 71, matching the size of the positioning component 61, is formed on the inner edge of each inner edge. The notch 71 is located directly above the support 72. This notch 71 facilitates the quick positioning and placement of the positioning component 61. Correspondingly, outer edges are provided on both sides of the top surface of the receiving box 6. After the hollow base 7 and the receiving box 6 are assembled and fastened together (as shown...), Figure 10 As shown), the outer edge closes the notch 71 to prevent impurities from entering the shoe box. The hollow base 7 has a support part 72 and at least two limiting parts 73 on both sides of the inner wall. The two limiting parts 73 form a guide limiting space. The automatic production line includes a support conveyor line, an assembly mechanism 3, a bagging mechanism 14 and a feeding mechanism. The support conveyor line is used to support and place the hollow base 7, and to transport the assembled shoe boxes through the bagging mechanism 14 for bagging. Assembly mechanism 3 includes a first robot arm 31 and a material picking component located at the output end of the first robot arm 31. The first robot arm 31 is used to drive the material picking component to move and grab the hollow base 7 and place it on the support conveyor line. Then, it grabs the receiving box 6 and moves the positioning component 61 to the support part 72. After that, it moves along the surface of the support part 72 into the guide limiting space, so that the receiving box 6 and the hollow base 7 are fastened and assembled. The bagging mechanism 14 is used to put at least one assembled shoebox into a bag; The unloading mechanism is used to unload the bagged shoe boxes on the support conveyor line. The unloading mechanism includes a second robot arm 17 and a clamping structure 24 located at the output end of the second robot arm 17. The clamping structure 24 includes a first clamping unit 241, a second clamping unit 242 and several suction cups 243. The first clamping unit 241 is used to clamp and fix two sides of the bagged shoe box, the second clamping unit 242 is used to clamp and fix the other two sides of the bagged shoe box, and the suction cups 243 are used to adsorb and fix one side of the bagged shoe box. The first clamping unit 241 here includes a sixth driving member 2411 (which can be a cylinder) and two first clamping plates 2412. The sixth driving member 2411 drives the two first clamping plates 2412 to move closer to or further away from each other. The second clamping unit 242 includes a seventh driving member 2421 (which can be a cylinder) and two second clamping plates 2422. The seventh driving member 2421 drives the two second clamping plates 2422 to move closer to or further away from each other. The first robotic arm 31 drives the picking component to grasp the hollow base 7 and place it on the support conveyor line, so that the opening of the hollow base 7 faces upward. Then, the first robotic arm 31 drives the picking component to grasp the receiving box 6, so that the positioning pieces 61 on both sides of the outer wall of the receiving box 6 are placed face-to-face on the support part 72 (at this time, the receiving box 6 is in the position of...). Figure 8 As shown in the tilted state, with the opening tilted upwards, it is convenient to place shoes in the receiving box 6. Then, the first robotic arm 31 drives the picking component to move the receiving box 6 horizontally along the support part 72, so that the positioning component 61 enters the guide limiting space (e.g., Figure 9 As shown), finally, adjust the material-grabbing component to stop gripping the receiving box 6, and the positioning component 61 moves along the guide limit space, so that the receiving box 6 and the hollow base 7 complete the automatic snap-fit ​​assembly work (as shown). Figure 10 As shown, this not only avoids the trouble of manual assembly, improves assembly efficiency, and reduces the intensity of manual labor, but also avoids the trouble of waiting for the injection-molded hollow base 7 and the housing 6 to cool down before assembly or the risk of burning hands. Afterwards, at least one assembled shoebox is conveyed to the bagging mechanism 14 via the support conveyor line for bagging and packaging. The second robotic arm 17 drives the clamping structure 24 to move, so that the suction cup 243 initially adheres to and fixes the bagged shoebox. Then, the first clamping unit 241 and the second clamping unit 242 are adjusted to adhere to and clamp the four sides of the shoebox respectively, thereby completing the stable fixation of the shoebox. This avoids the risk of unstable adhesion leading to the shoebox falling off or tearing the outer packaging bag that is easily encountered when using the suction cup 243 alone. Furthermore, the second robotic arm 17 drives the clamping structure 24 to move. 4. During material feeding, the bottom surface of the shoe box can directly contact the ground or the supporting surface of the storage component supporting the shoe box. This avoids the trouble of having to set up a drive structure to drive the bottom gripper to detach from the bottom surface of the shoe box when feeding, which is required for clamping the six sides of the shoe box to ensure stable placement. On the one hand, it saves the cost of setting up an additional drive structure, and on the other hand, it eliminates the action of driving the bottom gripper to detach from the bottom surface of the shoe box, reducing feeding time and improving feeding efficiency. This completes the rapid and automatic production of shoe boxes without manual labor, greatly saving human resources and improving production efficiency.

[0020] like Figure 1 As shown, the automated production line also includes a first injection molding machine 1 for injection molding hollow base 7 and a second injection molding machine 2 for injection molding container 6. The assembly mechanism 3 is located between the first injection molding machine 1 and the second injection molding machine 2, which facilitates the automatic unloading and assembly of the hollow base 7 produced by the first injection molding machine 1 and the container 6 produced by the second injection molding machine 2 in the first time. This shortens the material transfer path, improves assembly efficiency, reduces intermediate buffer equipment, and simplifies the production line footprint. The supporting conveyor lines include a first conveyor line 4, a third conveyor line 18, a fourth conveyor line 21, a fifth conveyor line 22, and a second conveyor line 16 arranged in an S-shape. The second injection molding machine 2 is located between the first conveyor line 4 and the fourth conveyor line 21. The bagging mechanism 14 is located between the second injection molding machine 2 and the second conveyor line 16. The fourth conveyor line 21 passes through the bagging mechanism 14. In addition, the automated production line also includes a vacuum heat shrink machine 15, which is located behind the bagging mechanism 14 and on the fourth conveyor line 21 to ensure that the shoe box is automatically conveyed for vacuum heat sealing after being bagged. This layout maximizes the use of space in a small factory, making it suitable for medium-sized workshops. The entire production line is centered around two injection molding machines, with a central assembly station and an S-shaped support conveyor line. It integrates injection molding, automatic assembly, and automatic bagging and heat shrinking into a fully automated process. No manual handling, assembly, or bagging is required, significantly reducing labor costs. Each process is arranged nearby with short conveyor paths, balancing production efficiency and space utilization. This solves the problems of traditional split production lines, such as large footprint, cumbersome transfer, low production efficiency, and easy damage to plastic parts. It is suitable for large-scale continuous production.

[0021] like Figure 2 and Figure 4 As shown, a first blocking part 10 and a second blocking part 11 are respectively provided on the adjacent sides of the periphery of the first conveyor line 4. A first pressing mechanism 8 is also provided on one side of the periphery of the first conveyor line 4. The first pressing mechanism 8 is used to press against the hollow base 7 so that the outer wall of the hollow base 7 abuts against both the first blocking part 10 and the second blocking part 11. The first blocking part 10 and the second blocking part 11 here are respectively the first vertical plate and the second vertical plate that are vertically arranged. The corresponding hollow base 7 is rectangular. The first pressing mechanism 8 includes a first driving member 81 (which can be a cylinder here) and a first pressing member 82 (which has a first pressing surface and a second pressing surface) located at the output end of the first driving member 81. When the first robot arm 31 drives the material picking member to move so that it grabs the injection-molded hollow base 7 and places it on the first conveyor line 4, the first pressing member 82 is driven to move by adjusting the first driving member 81. The first pressing surface and the second pressing surface of the first pressing member 82 are respectively aligned with the first pressing surface and the second pressing surface of the first pressing member 82. The two adjacent surfaces of the hollow base 7 are in contact and fit together, and the other two adjacent surfaces of the hollow base 7 are pushed to abut against the first blocking part 10 and the second blocking part 11 respectively, thereby completing the pressing and fixing of the hollow base 7. When the hollow base 7 is placed on the first conveyor line 4 and during the assembly of the container box 6, the first conveyor line 4 can stop to transport the contents, thereby further ensuring the stable assembly of the container box 6. After the container box 6 and the hollow base 7 are assembled, the first conveyor line 4 is started, and the first pressing mechanism 8 no longer fixes the hollow base 7, thus avoiding the trouble of having to rotate it to the conveyor line after assembly on a fixed support.

[0022] like Figure 2 and Figure 4 As shown, a fixing mechanism 9 is symmetrically provided on both sides of the periphery of the first conveyor line 4. The fixing mechanism 9 includes a second driving member 91 (which can be a cylinder) and a fixing member 92 (the fixing member 92 is provided with a pressure rod). When the hollow base 7 is located on the first conveyor line 4, the two second driving members 91 drive the two fixing members 92 to move closer to each other to clamp and fix the hollow base 7. When the first robotic arm 31 drives the material handling component to grasp the injection-molded hollow base 7 and place it on the first conveyor line 4, after the first clamping mechanism 8 initially fixes the hollow base 7, the second driving component 91 is adjusted to drive the two fixing components 92 to move closer to each other, so as to further stabilize and fix the hollow base 7.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the automated production line also includes a support frame 5 for supporting and placing the container box 6. The support frame 5 is provided with a positioning fixture 51 for positioning the container box 6. By setting the positioning fixture 51, it is convenient to accurately place the injection-molded container box 6 on the support frame 5, which facilitates the subsequent assembly mechanism 3 to perform secondary accurate material picking of the container box 6 on the support frame 5 and accurate installation with the hollow base 7. The material handling component here is a pneumatic suction cup. The output end of the first robotic arm 31 is fixedly installed with a support block 32. The support block 32 is equipped with several pneumatic suction cups. The support frame 5 here is a hollow support frame, which makes it convenient for the support block 32 to enter the storage box 6 placed under the support frame 5. Since the hollow base 7 has an opening at the top and the receiving box 6 has an opening on one side, after the first injection molding machine 1 produces the hollow base 7 and the second injection molding machine 2 produces the receiving box 6, it is necessary to use a pneumatic suction cup to adsorb the outer surfaces of the receiving box 6 and the hollow base 7 facing away from the opening. This makes it easier for the first robot arm 31 to pull the receiving box 6 and the hollow base 7 horizontally. The demolding direction is adapted to the ejection and unloading direction. With the existing ejection and unloading mechanism, unloading is more convenient and labor-saving. Compared with adsorbing other outer surfaces (which is a lateral clamping), the center of gravity of the hollow base 7 and the receiving box 6 is relatively far from the pneumatic suction cup. The hollow base 7 and the receiving box 6 are very easy to flip and shift around the adsorption point, which affects the accurate unloading and assembly of the hollow base 7 and the receiving box 6 in the future.

[0024] like Figure 3 As shown, the positioning fixture 51 includes four positioning blocks, at least one of which has a first abutting surface 511 and a second abutting surface 512. The automated production line also includes a second pressing mechanism 12 and a third pressing mechanism 13. The second pressing mechanism 12 is used to press the receiving box 6 so that one side of it abuts against the first abutting surface 511, and the third pressing mechanism 13 is used to press the receiving box 6 so that the other side of it abuts against the second abutting surface 512. The second clamping mechanism 12 includes a third driving component 121 (which can be a cylinder) and a second clamping component 122. The third clamping mechanism 13 includes a fourth driving component 131 (which can be a cylinder) and a third clamping component 132. When the first robotic arm 31 drives the material handling component (which is a pneumatic suction cup) to move, it adsorbs and fixes the A-side of the receiving box 6, which is injection molded by the second injection molding machine 2 (e.g., ...). Figure 6 As shown), the receiving box 6 is adsorbed and placed on the positioning fixture 51. Then, by adjusting the second clamping mechanism 12 and the third clamping mechanism 13, the receiving box 6 is moved so that the outer wall of the receiving box 6 abuts against the first contact surface 511 and the second contact surface 512 respectively, thereby completing the stable positioning and fixing of the receiving box 6. Subsequently, the second clamping member 122 and the third clamping member 132 are adjusted so that they no longer contact the receiving box 6, thereby facilitating the first robot arm 31 to drive the material picking component to move and adsorb and fix the B side of the receiving box 6 (as shown). Figure 6As shown, after the container box 6 and the hollow base 7 are assembled, the bottom and sides of the container box 6 are inside the hollow base 7, which facilitates the quick and automatic assembly of the container box 6 and the hollow base 7.

[0025] like Figure 1 and Figure 14 As shown, the automated production line also includes a first transfer mechanism 19 for transferring shoe boxes from the first conveyor line 4 to the third conveyor line 18 and a second transfer mechanism 20 for transferring the third conveyor line 18 to the fourth conveyor line 21. The second transfer mechanism 20 and the first transfer mechanism 19 have the same structure. Specifically, both the first transfer mechanism 19 and the second transfer mechanism 20 include a frame 191, a pneumatic horizontal slide rail structure 192 mounted on the frame 191, a lifting cylinder 193 mounted on the pneumatic horizontal slide rail structure 192, and a pneumatic clamping unit 194 mounted at the output end of the lifting cylinder 193. With this setup, when the assembled shoeboxes on the first conveyor line 4 need to be transferred to the third conveyor line 18, the shoeboxes are blocked by a stop at the end of the first conveyor line 4. The lifting cylinder 193 and the driving pneumatic clamping unit 194 are moved to directly above the shoeboxes by adjusting the pneumatic horizontal slide rail structure 192. Then, the lifting cylinder 193 is adjusted to drive the driving pneumatic clamping unit 194 to move down, and then the driving pneumatic clamping unit 194 is adjusted to clamp the shoeboxes on the first conveyor line 4. Then, the pneumatic horizontal slide rail structure 192 is adjusted to move the shoeboxes to the third conveyor line 18. Finally, the pneumatic clamping unit 194 is adjusted to stop clamping and fixing the shoeboxes. Similarly, when the shoeboxes on the third conveyor line 18 are transferred to the fourth conveyor line 21, the working principle is the same. The end of the third conveyor line 18 is also equipped with a stop, which will not be described in detail here. Since the assembled shoeboxes have not yet been bagged at this time, it is not necessary to clamp and fix the six sides of the shoeboxes separately to achieve stable clamping.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 15 As shown, both the first conveyor line 4 and the fourth conveyor line 21 include a support frame and two synchronous conveyor belts with a gap in the middle, which are mounted on the support frame. By setting the first conveyor line 4 as a synchronous conveyor belt, after a hollow base 7 and a receiving box 6 are assembled into a shoe box, the first pressing mechanism 8 and the fixing mechanism 9 are adjusted to no longer fix the hollow base 7, and the synchronous conveyor belt is started. Thus, the assembled shoe box is transported away from the first pressing mechanism 8, the fixing mechanism 9 and the assembly mechanism 3 by the synchronous conveyor belt, which makes it convenient for the next injection-molded hollow base 7 to be placed on the first conveyor line 4 for the assembly of the next shoe box. This avoids the possible danger of manual handling of the assembled shoe box by approaching the assembly mechanism 3. There is a gap between the two synchronous conveyor belts, which makes it convenient for the support block 32 to enter between the two synchronous conveyor belts to place the hollow base 7, so that the hollow base 7 is placed on the first conveyor line 4 with the opening facing upward.

[0027] like Figure 15 As shown, the support frame of the fourth conveyor line 21 is also equipped with a steering synchronous conveyor belt 23 that is horizontal and perpendicular to the conveying direction of the fourth conveyor line 21. With this configuration of the steering synchronous conveyor belt 23, after the shoe boxes in bags are vacuum-sealed and transported via the fourth conveyor line 21 to the steering synchronous conveyor belt 23, the fourth conveyor line 21 is stopped, and the steering synchronous conveyor belt 23 is started to transfer the bagged shoe boxes to the fifth conveyor line 22. Since the shoe boxes here have bags covering them, using a single pneumatic clamping unit 194 of the first transfer mechanism 19 to clamp both sides of the shoe box would result in unstable clamping. Therefore, a transfer mechanism similar to the first transfer mechanism 19 or the second transfer mechanism 20 is not used here. Using a feeding mechanism for transfer is not only cumbersome but also too costly. This multi-layered conveyor belt 23... The combined use of various conveyor lines and multiple transfer structures (first transfer mechanism 19 and steering synchronous conveyor belt 23) can minimize equipment costs and installation and subsequent handling difficulties while ensuring the normal operation of the entire production line. Although the installation and handling of the two intermediate synchronous conveyor belts and steering synchronous conveyor belt 23 are more troublesome than those of the third conveyor line 18 and the fifth conveyor line 22, which are a single wide belt, and the contact area between the two intermediate synchronous conveyor belts and the shoe boxes is smaller than that of the wide belt conveyor line due to the gap, the conveying effect is not as good as that of the wide belt conveyor line. However, it can ensure the normal transfer of shoe boxes while saving on the setting of transfer mechanisms.

[0028] like Figure 12 and Figure 13 As shown, the output end of the second robotic arm 17 is fixedly mounted with a support plate 244. The support plate 244 is provided with a clamping structure 24 and a first baffle 240. The second conveyor line 16 includes a support frame and two synchronous conveyor belts with a gap in the middle, which are provided on the support frame. The second conveyor line 16 is provided with at least one blocking mechanism 25. The first baffle 240 and the blocking mechanism 25 limit the two ends of the shoe box on the second conveyor line 16. After the shoebox to be unloaded is transferred to the fifth conveyor line 22 via the turning synchronous conveyor belt 23, it is then slowly conveyed vertically from the fifth conveyor line 22 to the second conveyor line 16 until the adjusting blocking mechanism 25 is positioned at one end of the shoebox. Then, the second robotic arm 17 is adjusted to move the support plate 244, thereby moving the first baffle 240 so that the first baffle 240 is positioned at the other end of the shoebox. Finally, the second robotic arm 17 is adjusted to move the support plate 244, causing it to move the first baffle 240 and push the shoebox so that both ends of the shoebox are respectively aligned with the first baffle. The plate 240 and the blocking mechanism 25 abut against each other, thereby adjusting and limiting the position of the shoe box before the unloading mechanism unloads the material, preventing the shoe box from continuously moving on the second conveyor line 16 during the unloading process (the second conveyor line 16 can also be temporarily stopped during the unloading process), ensuring that the position of the shoe box grabbed by the unloading mechanism is constant each time it unloads the material, and that the first baffle 240 is located above the shoe box during unloading, which can realize the normal unloading of the shoe box from a horizontal position to a vertical position on the second conveyor line 16 (e.g., Figure 5 As shown, the top surface of the container 6 has a protrusion, and multiple shoe boxes cannot be stacked well in a horizontal state, so they are stacked vertically.

[0029] Specifically, the blocking mechanism 25 here includes a fifth driving member 251 (which can be a cylinder) and a second baffle 252. The fifth driving member 251 is used to drive the second baffle 252 to move along a direction perpendicular to the top surface of the second conveyor line 16. With this setup, when the second baffle 252 needs to be used in conjunction with the first baffle 240 to limit the shoe box, the fifth drive component 251 is adjusted to move the second baffle 252 upward, so that the second baffle 252 is located at one end of the shoe box. After a shoe box is limited and gripped, the fifth drive component 251 is adjusted to move the second baffle 252 downward, so as to ensure that subsequent shoe boxes are transported normally on the second conveyor line 16.

[0030] like Figure 12 As shown, the second conveyor line 16 includes a support frame and two synchronous conveyor belts with a gap between them, which are set on the support frame. The blocking mechanism 25 is set on the support frame. By setting the synchronous conveyor belts, the automatic conveying of shoe boxes with bags can be realized, thereby realizing automatic and uninterrupted clamping and unloading. When unloading the shoe box at the front, the blocking mechanism 25 can also block the subsequent shoe boxes to prevent two adjacent shoe boxes from colliding.

[0031] like Figure 12 As shown, the support frame is equipped with limiting plates 26 on both sides. The limiting plates 26 are located outside the two synchronous conveyor belts. By setting the limiting plates 26, the shoe box is stably transmitted on the two synchronous conveyor belts and will not be offset, thereby ensuring the accuracy of subsequent material feeding.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
