Description

A closure box method and system Technical Field

[0001] This invention relates to the field of automated equipment technology, and more specifically, to a closed-box method and system. Background Technology

[0002] The existing automated packaging production line mainly includes a conveying mechanism, a closing station, and supporting control components. The conveying mechanism is used to realize the directional transmission of the packaging box. After the packaging box to be closed is stably transported to the closing station, the closing station performs the closing action after the packaging box is in place. After the closing process is completed, the conveying mechanism continues to transport the packaging box to the next station.

[0003] This requires pausing the conveying action after the packaging box is transported to the closing station, and resuming the conveying after the closing is completed. This makes it impossible for the conveying link of the production line to maintain a continuous operation, causing intermittent interruptions in the overall operation process of the production line, which in turn leads to low overall operating efficiency of the entire automated packaging production line.

[0028] Another insertion part drives another part of the cover body to move at a second speed to form an engaging connection between the first lower cover and the inner peripheral wall of the box bottom unit, thereby closing the opening side of the box bottom unit with the top cover body.

[0034] A box includes a bottom unit and a bottom cover unit; the bottom unit is a shell with one open end; the bottom cover unit includes a second bottom cover and a first bottom cover; one end of the second bottom cover and one end of the first bottom cover are movably connected to the open side of the bottom unit, and the other ends extend away from the bottom unit; the second bottom cover and the first bottom cover are spaced apart on both sides of the open side of the bottom unit along a first direction.

[0035] A conveying assembly for conveying the box;

[0038] The box closing system includes a first working state and a second working state.

[0039] To address the issue of needing to pause the conveyor operation during the box-closing process, this invention offers the following advantages:

[0040] The box is driven to move along a first direction to a first state by a conveying component. The first folding component drives the first lower cover of the box to move away from the bottom unit towards the space surrounded by the bottom unit. The box continues to move along the first direction until the second lower cover is within the movement range of the second folding component and is spaced apart from it. Finally, the box continues to move along the first direction while the second folding component drives the second lower cover towards the space surrounded by the bottom unit to a second state. The first and second lower covers abut against the first folding component. The folding action of the first and second lower covers can be completed sequentially during the continuous conveying of the box. This allows the box closing process to be synchronized with the box conveying action without pausing the conveying operation of the conveying component. This ensures the continuous operation of the conveying link of the production line, avoids intermittent interruptions in the conveying process, and keeps the overall operation process of the automated packaging production line continuous. Ultimately, this solves the problem of low production line operating efficiency caused by the need to stop and wait for the existing box closing process, and improves the overall operating efficiency of the entire automated packaging production line.

[0047] The present disclosure will now be discussed with reference to several exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the present disclosure, and are not intended to imply any limitation on the scope of the disclosure.

[0049] In existing automated packaging production lines, during the box-closing process, when the conveying component drives the box to move along a first direction, the conveying action must be paused after the box is transported to the corresponding box-closing station. The conveying action resumes only after the first folding component completes its driving action on the first lower cover and the second folding component completes its driving action on the second lower cover. This prevents the simultaneous movement of the first and second lower covers towards the space enclosed by the box bottom unit while the box continues to move along the first direction. Consequently, the conveying process of the production line cannot maintain continuous operation, and the box conveying and box-closing actions of the first and second folding components cannot be synchronized. This leads to intermittent interruptions in the overall workflow of the automated packaging production line, and the box-closing process cannot be seamlessly connected to the box conveying process. The box includes a box bottom unit and a lower cover unit. The box bottom unit is a shell with one open end. The lower cover unit includes a second lower cover and a first lower cover. One end of the second lower cover and one end of the first lower cover are movably connected to the open side of the box bottom unit, while the other ends extend away from the box bottom unit. The second and first lower covers are spaced apart on both sides of the open side of the box bottom unit along the first direction.

[0050] Example 1:

[0051] This embodiment discloses a box closure method, as shown in Figure 1. The box closure method includes steps S10, S20, and S30; steps S10, S20, and S30 are executed sequentially.

[0052] Step S10: The conveying component 10 drives the box 80 to move along the first direction 91 to the first state; wherein, the first state includes the first folding component 20 driving the first lower cover 821 of the box 80 to move away from the bottom unit 81 of the box 80 toward the space surrounded by the bottom unit 81; in this way, the first lower cover 821 of the box 80 is folded during the conveying process without stopping the conveying component 10, ensuring that the conveying action of the production line is not interrupted.

[0053] Step S20: The box 80 continues to move along the first direction 91 until the second lower cover 822 of the box 80 is located within the movement range of the second folding assembly 30 and is spaced apart from the second folding assembly 30; wherein, the second folding assembly 30 and the first folding assembly 20 are arranged sequentially along the first direction 91. In this way, during the movement of the box 80, the first folding assembly 20 first folds the first lower cover 821, and as the box 80 moves subsequently, the second lower cover 822 moves to a position within the movement range of the second folding assembly 30, making it convenient for the second folding assembly 30 to fold the second lower cover 822.

[0054] Step S30: The box 80 continues to move along the first direction 91 while the second folding component 30 drives the second lower cover 822 to move towards the enclosing space of the box bottom unit 81 to the second state; wherein, the second lower cover 822 and the first lower cover 821 are arranged sequentially along the first direction 91, and the second state includes the first lower cover 821 and the second lower cover 822 respectively abutting against the first folding component 20. In this way, the second lower cover 822 is folded while the box 80 is moving continuously, and the conveying component 10 does not need to stop (that is, the box 80 does not need to stop moving along the first direction 91) to fold the first lower cover 821 and the second lower cover 822 respectively. The conveying component 10 does not pause the conveying process throughout the process, eliminating the need for the conveying component 10 to stop and interrupt the conveying process, making the entire production line more continuous and able to maintain high operating efficiency.

[0055] The box 80 also includes a top cover unit 83; one end of the top cover unit 83 is connected to the open side of the bottom unit 81, and the other end extends away from the bottom unit 81; the top cover unit 83 is disposed on one side of the bottom unit 81 along the second direction 92; the closing system also includes a third folding assembly 40 and a closing assembly 70; the distance between the third folding assembly 40 and the conveying assembly 10 gradually decreases along the first direction 91; the first folding assembly 20 and the closing assembly 70 are arranged sequentially along the first direction 91.

[0056] Furthermore, the box closure method also includes steps S40, S50, and S60; steps S10, S20, S30, S40, S50, and S60 are executed sequentially.

[0057] Step S40: As the box 80 continues to move along the first direction 91, the second folding component 30 drives the second lower cover 822 to move towards the enclosing space of the bottom unit 81 to the second state. The conveying component 10 drives the box 80 to move along the first direction 91 to the third state. The third state includes the third folding component 40 driving the top cover unit 83 of the box 80 to move away from the bottom unit 81 towards the enclosing space of the bottom unit 81. The top cover unit 83 is located on the side of the lower cover unit 82 away from the bottom unit 81. The lower cover unit 82 includes a first lower cover 821 and a second lower cover 822. Thus, during the continuous movement of the box 80 along the first direction 91, the third folding component 40 performs an initial fold on the top cover unit 83, facilitating subsequent closing of the top cover unit 83.

[0058] Step S50: Based on the closing system being in the third state, the conveying component 10 continues to drive the box 80 to move along the first direction 91 to the fourth state; wherein, the fourth state includes the lower cover unit 82 being located within the projection range of the top cover unit 83 toward the bottom unit 81, and the conveying component 10 driving the box 80 to move to the working area of ​​the closing component 70.

[0059] In this way, during the continuous conveying of box 80, the relative alignment of top cover unit 83 and bottom cover unit 82 is completed, and box 80 is synchronously conveyed to the working area of ​​closing component 70. There is no need to stop the production line for alignment work, ensuring the continuity of the box closing process and the conveying process, and making preparations for the final closing process.

[0060] Step S60: The closing component 70 drives the top cover unit 83 to move away from the bottom unit 81 to the opening side of the bottom unit 81. In this way, the box body is finally closed by the closing component 70 while the box 80 is continuously moving. This realizes the entire process of folding the first bottom cover 821, folding the second bottom cover 822, folding the top cover unit 83, and finally closing the box body. This completely eliminates the downtime of the conveyor component 10 during the box closing process and improves the operating efficiency of the production line.

[0061] Furthermore, the top cover unit 83 includes a top cover body 831 and an insert cover body 832; one end of the top cover body 831 is connected to the opening side of the bottom box unit 81, and the other end extends away from the bottom box unit 81; the top cover body 831 is disposed on one side of the bottom box unit 81 along the second direction 92; one end of the insert cover body 832 is connected to the side of the top cover body 831 away from the bottom box unit 81, and the other end extends away from the bottom box unit 81; the closing system also includes a fourth folding assembly 50; the first folding assembly 20, the fourth folding assembly 50, and the closing assembly 70 are arranged sequentially along the first direction 91.

[0062] Step S50 includes steps S51, S52, and S53; steps S10, S20, S30, S40, S51, S52, S53, and S60 are executed sequentially.

[0063] Step S51: Based on the closing box system being in the third state, the conveying component 10 drives the box 80 to move into the working area of ​​the fourth folding component 50;

[0064] Step S52: The fourth folding assembly 50 drives the insert cover 832 of the top cover unit 83 to move towards the enclosing space of the bottom unit 81 relative to the top cover 831, moving it to a fifth state. The fifth state includes a minimum angle between the insert cover 832 and the top cover 831 within a fourth angle range. During the continuous transport of the box 80, the fourth folding assembly 50 pre-folds and limits the angle of the insert cover 832 of the top cover unit 83, ensuring that the insert cover 832 and the top cover 831 maintain a suitable angle range, facilitating the subsequent closing of the top cover unit 83. The fourth angle range can be 90°±5°.

[0065] Step S53: The conveying component 10 continues to drive the box 80 to move along the first direction 91 to the fourth state; wherein, the fourth state also includes the lower cover unit 82 being located within the projection range of the top cover body 831 towards the bottom unit 81, and the conveying component 10 driving the box 80 to move into the working area of ​​the closing component 70. In this way, the box 80 continues to move uninterruptedly along the first direction 91, while the lower cover unit 82 is precisely positioned within the projection range of the top cover body 831, and the box 80 is delivered into the working area of ​​the closing component 70, realizing a seamless connection of the final closing process, maintaining continuous conveying throughout the process, providing a precise positional basis for the final closing, and further improving the box closing accuracy and process stability.

[0066] Further, the fourth folding assembly 50 includes a support portion 51, two deformation units 52, and two deformation driving portions 53; the first folding assembly 20, the support portion 51, and the closing assembly 70 are arranged sequentially along the first direction 91; the conveying assembly 10, the support portion 51, and the deformation unit 52 are arranged sequentially along the third direction 93; the deformation unit 52 includes a first deformation portion 521 and a second deformation portion 522; the two first deformation portions 521 are arranged sequentially along the first direction 91; one deformation driving portion 53 is drivenly connected to one first deformation portion 521; one end of the second deformation portion 522 is connected to the first deformation portion 521, and the other end extends toward the support portion 51; the minimum working surfaces of the first deformation portion 521 and the second deformation portion 522 are within the range of the included angle of the fourth angle.

[0067] Step S53 includes steps S531, S532, and S533; steps S10, S20, S30, S40, S51, S52, S531, S532, S533, and S60 are executed sequentially.

[0068] Step S531: The conveying assembly 10 continues to drive the box 80 to move a first set distance along the first direction 91; wherein, the fifth state also includes the support part 51, the top cover 831, and the two first deformable parts 521 abutting in sequence along the third direction 93, and the support part 51, the insert cover 832, and the two second deformable parts 522 abutting in sequence along the second direction 92, the minimum included angle between the top cover 831 and the insert cover 832 being within the fourth angle range; the first set distance is less than the length of one deformable unit 52 along the first direction 91. In this way, the support part 51, the first deformable parts 521, and the second deformable parts 522 respectively form a stable support with the top cover 831 and the insert cover 832, which can keep the top cover 831 and the insert cover 832 from rebounding and deforming within the fourth angle range, realizing the shaping and positioning of the top cover unit 83, and avoiding the top cover unit 83 and the insert cover 832 from angular displacement or structural loosening due to excessive conveying displacement.

[0069] Step S532: The deformable unit 52 near the first folding assembly 20 is moved to a position spaced apart from the top cover unit 83. This separates the deformable unit 52 from the top cover unit 83, preventing interference between the box 80 and the deformable unit 52 during subsequent transport.

[0070] Step S533: The conveying component 10 continues to drive the box 80 to move along the first direction 91 to the fourth state.

[0071] In this way, through steps S531, S532, and S533, while maintaining continuous operation of the production line without downtime, a shaping support for the pre-folded top cover unit 83 can be added. Moreover, the deformation unit 52 can be disengaged without interfering with the box 80, which greatly improves the accuracy of box forming and the efficiency of the production line.

[0072] Furthermore, the closing system also includes a shaping component 60; the fourth folding component 50, the shaping component 60, and the closing component 70 are arranged sequentially along the first direction 91.

[0073] Step S60 includes steps S61 and S62; steps S10, S20, S30, S40, S51, S52, S531, S532, S533, S61, and S62 are executed sequentially.

[0074] Step S61: The shaping component 60 drives the insert cover 832 to move to the sixth state via the top cover body 831; wherein, the sixth state includes the distance along the first direction 91 between the side of the insert cover 832 near the shaping component 60 and the side of the outer periphery of the box bottom unit 81 near the shaping component 60 being less than the second set distance; in this way, the top cover body 831 eliminates the box body twisting deformation generated during the synchronous movement of the top cover unit 83 and the box 80 clamped by the deformable part and the support part 51, corrects the position of the box body and the insert cover 832, avoids misalignment or closure failure during subsequent box closing, and ensures the stability of the entire box closing process. The second set distance can be 1mm~10mm.

[0075] Step S62: The closing component 70 drives the top cover unit 83 to move from the side away from the bottom unit 81 to the opening side of the bottom unit 81. In this way, with the shape of the box 80 corrected, the closing component completes the closure of the top cover unit 83, improving the reliability of the closure of the top cover unit 83.

[0076] Further, step S60 is as follows:

[0077] The closing component 70 drives the insert cover 832 to move to the inner peripheral wall of the bottom unit 81 and form an engaging connection with the lower cover unit 82, thereby closing the opening side of the bottom unit 81 with the top cover 831. In this way, the insert cover 832 forms a limiting fit with the bottom unit 81 and the lower cover unit 82, which can prevent the top cover 831 from springing back or loosening, thereby improving the structural stability of the closed box.

[0078] Furthermore, the closing assembly 70 includes two insertion parts 72 and two insertion driving parts 73; one insertion driving part 73 is drivenly connected to one insertion part 72; the first folding assembly 20, the fourth folding assembly 50, one insertion part 72, and the other insertion part 72 are arranged sequentially along the first direction 91.

[0079] Step S60 includes steps S63 and S64. Steps S53, S63, and S64 are executed sequentially.

[0080] Step S63: An insertion part 72 near the first folding assembly 20 drives a portion of the cover 832 near the first folding assembly 20 to move at a first speed to form a locking connection between the second lower cover 822 and the inner peripheral wall of the box bottom unit 81. The upstream cover 832 is constrained for a longer time in the previous process, resulting in a better shaping effect. This allows for a more precise insertion of the upstream cover 832 between the box bottom unit 81 and the second lower cover 822 unit 82, while also providing a locking reference for the subsequent insertion of the cover 832 on the other side.

[0081] Step S64: Another insertion part 72 drives another part of the cover body 832 to move at a second speed to form a locking connection between the first lower cover 821 and the inner peripheral wall of the box bottom unit 81, thereby closing the opening side of the box bottom unit 81 with the top cover body 831. In this way, the cover body 832 is locked in place in two parts in an orderly and high-precision manner, which can effectively ensure the closure of the top cover body 831 and the box bottom unit 81, thereby improving the accuracy of the insertion of the cover body 832 into the inner peripheral wall of the second lower cover 822 and the box bottom unit 81, and ensuring the stable operation of the production line.

[0082] Further, step S63 includes steps S631 and S632; steps S10, S20, S30, S40, S51, S52, S53, S631, S632, and S64 are executed sequentially:

[0083] Step S631: The adsorption unit 71 drives the bottom unit 81 of the box to move a third predetermined distance away from the space enclosed by the bottom unit 81, on the side closest to the cover body 832. This actively increases the assembly gap between the second lower cover 822 and the inner peripheral wall of the bottom unit 81, providing sufficient clearance for the insertion of the cover body 832 and preventing interference between the cover body 832 and the box body and the lower cover unit 82 when inserted. The third predetermined distance can be 5mm to 15mm.

[0084] Step S632: An insertion part 72 near the first folding assembly 20 drives a portion of the cover 832 near the first folding assembly 20 to move until it forms a locking connection between the second lower cover 822 and the inner peripheral wall of the box bottom unit 81. In this way, even with an assembly gap between the second lower cover 822 and the inner peripheral wall of the box bottom unit 81, the cover 832 can be stably inserted between the second lower cover 822 and the inner peripheral wall of the box bottom unit 81 and form a locking connection, avoiding interference between the cover 832 and the box body and the lower cover unit 82 during insertion, thus ensuring the efficient operation of the production line.

[0085] Furthermore, since the first speed is less than the second speed, after the upstream cover 832 has been inserted between the second lower cover 822 and the inner peripheral wall of the box bottom unit 81, the downstream cover 832 is driven to quickly insert between the first lower cover 821 and the inner peripheral wall of the box bottom unit 81 at a faster speed, which can shorten the time spent on the downstream cover and improve the efficiency of the entire production line.
