Description

Technical Field

[0001] This invention relates to the field of split-and-combination reversible packaging box technology, specifically to a split-and-combination reversible packaging box conveyor line based on stable conveying. Background Technology

[0002] Packaging box conveying devices are part of the packaging box production line. They are used to transport packaging boxes to various processing stations. With the development of commodity economy, products often need to be transported over long distances after assembly for circulation. Correspondingly, it is necessary to protect the products and facilitate handling to avoid damage during long-distance transportation and facilitate circulation. To meet the needs of product protection, packaging boxes have emerged. Packaging boxes can wrap products according to different application requirements to provide products with sealing, shockproof and other protection.

[0003] However, existing packaging boxes present several problems during production line transport. When a large number of neatly arranged boxes pass through corners or bends of the conveyor line, their high inertia and excessive speed can easily cause them to tip over. Furthermore, during transport, boxes are susceptible to external impacts or pressure from adjacent boxes, leading to tilting, deflection, or even falling. These issues can cause blockages in the conveyor line, affecting its normal operation. The excessive length of the conveyor line also makes it difficult to respond to and address blockages promptly, further exacerbating the congestion and severely impacting the efficiency of box transport.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a split-and-combine reversing packaging box conveyor line based on smooth conveying, so as to solve the technical defects mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a splitting and reversing packaging box conveyor line based on smooth conveying, comprising multiple sets of straight frames and curved frames, wherein conveyor belts are provided inside the straight frames and curved frames, the straight frames are installed at both ends of the curved frames, and curved rails that cooperate with the curved frames are fixedly installed on the top of the curved frames, and electric sliding seats are slidably connected inside the curved rails, and the unblocking component is located at the bottom of the electric sliding seats;

[0007] The unblocking component includes a sliding plate disposed below an electric sliding seat. A linear stepping rail is fixedly connected to the bottom of the sliding plate. An electric slider is slidably connected inside the linear stepping rail. A horizontal plate is fixed to the bottom of the electric slider by bolts. A rotating plate is movably connected to the bottom of the horizontal plate by a bearing. A clamping plate is fixedly connected to the bottom of the rotating plate.

[0008] Furthermore, an electric push cylinder is rotatably connected to the bottom of the horizontal plate, a drive rail is fixedly connected to the top of the rotating plate, a drive block is fixedly connected to the output end of the electric push cylinder, and the drive block is slidably connected within the drive rail.

[0009] Furthermore, the side wall of the clamp is provided with an I-shaped groove, and the unblocking component also includes a limiting plate. An anti-slip pad is fixedly installed on the side wall of the limiting plate, and an I-shaped protrusion is fixedly connected to the other side wall of the limiting plate. The I-shaped protrusion is slidably connected in the I-shaped groove, and a compression spring is provided in the I-shaped groove. The two ends of the compression spring are fixedly connected to the inner wall of the I-shaped groove and the side wall of the I-shaped protrusion, respectively.

[0010] Furthermore, a support base is provided at one end of the linear frame, and a lane changing and separating assembly is provided above the support base. The lane changing and separating assembly includes a feeding track and two separating tracks. The feeding track and the separating tracks are both located on the top of the support base, and a support frame is fixedly connected to the top of the support base.

[0011] Furthermore, the bottom of the support frame is movably connected to a material transfer track via a bearing, and the top of the support frame is movably mounted with an electric push cylinder via a bearing. A connecting plate is fixedly connected to the top of the material transfer track, and the output end of the electric push cylinder is rotatably connected to the top of the connecting plate. Blockage sensors are fixedly installed on the side walls of both the support frame and the bending frame.

[0012] Furthermore, the bottom of the electric sliding seat is symmetrically and fixedly connected with an I-shaped slide rail, the sliding plate is slidably connected to the bottom of the I-shaped slide rail, and a swing rod is movably connected to the center of the bottom of the electric sliding seat through a bearing. Both ends of the swing rod are rotatably connected with a linkage rod, and the end of the linkage rod away from the swing rod is rotatably connected to the sliding plate.

[0013] Furthermore, an electric push cylinder three is symmetrically fixed to the bottom of the electric sliding seat, and the output end of the electric push cylinder three is fixedly connected to the side wall of the sliding plate.

[0014] Furthermore, a control panel is fixedly mounted on the side wall of the linear frame via a bracket, and a camera is fixedly mounted on the side wall of the electric sliding seat.

[0015] This invention also proposes an operation method for a split-and-combination reversing packaging box conveyor line based on smooth conveying, specifically including the following steps:

[0016] Step 1: After the blockage sensor detects that the packaging box is blocked at the bend of the bending frame, the camera takes pictures of the blockage and analyzes the deflection, tilting and blockage of the blocked packaging box. The control panel controls the electric push cylinder 2 to start, which in turn drives the turntable to deflect until the corresponding two limit plates match the side of the currently blocked and deflected packaging box.

[0017] Step Two: Activate the electric push cylinder three. The electric push cylinder three drives the sliding plate to move horizontally until the corresponding limit plate contacts and adheres to the edge of the packaging box. During the process of the limit plate adhering to the edge of the packaging box, the tilted packaging box is uprighted by the action of the limit plate. Then, the electric push cylinder two is activated simultaneously, which drives the rotating plate and the limit plate to deflect in the opposite direction. The limit plate slides relative to the clamping plate and slides synchronously with the deflection of the packaging box, thus effectively avoiding the problem of the packaging box being further squeezed and deformed during the correction process.

[0018] Using the same method, the packaging boxes that were blocking the bending frame were processed one by one until the blockage was completely removed.

[0019] Step 3: Start the electric push cylinder one, which will drive the transfer track to deflect until the transfer track is connected to another distribution track. At this time, these defective packaging boxes flow into the rework area through the distribution track for re-inspection, so that qualified packaging boxes can be put back into the qualified processing area. After these defective packaging boxes have completely flowed into the rework area, the electric push cylinder one will reconnect the transfer track with the corresponding distribution track.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In use, this invention incorporates a blockage sensor inside the bending frame. When the sensor detects a package blocking the bend in the frame, it immediately sends a blockage signal to the control panel. A camera captures the blockage, and an internal data analysis module analyzes the images to assess the package's deflection, tilting, and the number of blocks. This allows for the control of two sets of limit plates to adjust the deflection of adjacent tilted or deflected packages until they align with the corresponding package edges. The limit plates, in conjunction with I-shaped grooves and compression springs, correct the packaging with minimal damage, allowing it to resume transport on the conveyor line. This enables a rapid response and efficient handling of package blockage issues, maximizing the efficiency of the conveyor line.

[0022] 2. In use, the present invention, by setting up a lane changing and separating component, the electric push cylinder, through its cooperation with the connecting plate, drives the material transfer track to deflect, thereby realizing the flexible switching between the material transfer track and multiple material separation tracks. By connecting with different material separation tracks, the defective packaging boxes can be directionally transported by track and area. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figures 1-8 As shown, when the conveyor belt speed is too high, the packaging boxes may have too much inertia at turns, making them unable to maintain stability. This is especially true at corners or turns of the conveyor line, where packaging boxes are more likely to get stuck, leading to more serious blockages in subsequent packaging boxes. To solve this problem, the following improvements are made:

[0036] The packaging box conveyor line based on smooth conveying includes multiple sets of straight frames 1 and curved frames 2. Both straight frames 1 and curved frames 2 are equipped with conveyor belts. The straight frames 1 are installed at both ends of the curved frames 2. The top of the curved frames 2 is fixedly installed with curved rails 5 that cooperate with the curved frames 2. The curved rails 5 are slidably connected to the inside of the curved rails 5. The unblocking component 4 is set at the bottom of the electric sliding seat 6.

[0037] The unblocking component 4 includes a sliding plate 401 disposed below the electric sliding seat 6. A linear stepping rail 402 is fixedly connected to the bottom of the sliding plate 401. An electric slider 403 is slidably connected inside the linear stepping rail 402. A horizontal plate 404 is fixed to the bottom of the electric slider 403 by bolts. A rotating plate 405 is movably connected to the bottom of the horizontal plate 404 by bearings. A clamping plate 406 is fixedly connected to the bottom of the rotating plate 405.

[0038] The bottom of the horizontal plate 404 is rotatably connected to an electric push cylinder 407, the top of the rotating plate 405 is fixedly connected to a drive rail 408, the output end of the electric push cylinder 407 is fixedly connected to a drive block 409, and the drive block 409 is slidably connected inside the drive rail 408.

[0039] The side wall of the clamp 406 is provided with an I-shaped groove 410. The unblocking component 4 also includes a limiting plate 411. The side wall of the limiting plate 411 is fixedly installed with an anti-slip pad. By setting the anti-slip pad, the friction with the packaging box can be increased, and damage to the outside of the packaging box can be reduced.

[0040] The bottom of the electric sliding seat 6 is symmetrically and fixedly connected to an I-shaped slide rail 11. The sliding plate 401 is slidably connected to the bottom of the I-shaped slide rail 11. The center of the bottom of the electric sliding seat 6 is movably connected to a swing rod 12 through a bearing. Both ends of the swing rod 12 are rotatably connected to a linkage rod 13. The end of the linkage rod 13 away from the swing rod 12 is rotatably connected to the sliding plate 401.

[0041] Electric push cylinder 3 14 is symmetrically fixed at the bottom of the electric sliding seat 6. The output end of the electric push cylinder 3 14 is fixedly connected to the side wall of the sliding plate 401. The control panel 16 is fixedly installed on the side wall of the linear frame 1 through the bracket. The camera 15 is fixedly installed on the side wall of the electric sliding seat 6. The blockage sensor 10 is fixedly installed on the side wall of the support frame 8 and the bending frame 2. It should be noted that the blockage sensor 10 is existing technology and is commonly used in conveyor lines.

[0042] In specific settings, when the packaging box passes through the bending frame 2, if it deflects or tilts due to factors such as excessive conveying speed or collision, the blockage sensor 10 located inside the bending frame 2 will detect that the packaging box is blocked at the bend of the bending frame 2. The blockage sensor 10 will send the packaging box blockage signal to the control panel 16. The control panel 16 will control the electric sliding seat 6 to slide in a direction along the bottom of the curved rail 5 until the electric sliding seat 6 moves to the designated position.

[0043] The camera 15 takes pictures of the blockage at the bending frame 2 and analyzes the pictures using its internal data analysis module. This analysis includes the deflection, tilting, and number of blocked packaging boxes. The analysis is then sent to the control panel 16, which starts the electric push cylinder 407. The electric push cylinder 407, through the cooperation of the drive block 409 and the drive rail 408, drives the rotating plate 405 to deflect until the two corresponding limit plates 411 match the side of the currently blocked and deflected packaging box.

[0044] like Figure 6 As shown, the bottom of the sliding plate 401 is provided with two sets of limiting plates 411. The two sets of limiting plates 411 adjust the deflection of the adjacent packaging box edges that are tilted or deflected in a corresponding manner until the two sets of limiting plates 411 match the corresponding packaging box edges.

[0045] Then, the electric push cylinder 3 14 is activated, which drives the sliding plate 401 to move horizontally along the I-shaped slide rail 11 until the corresponding limit plate 411 contacts and adheres to the edge of the packaging box. During the process of the limit plate 411 adhering to the edge of the packaging box, the tilted packaging box is straightened by the action of the limit plate 411. Then, the electric push cylinder 2 407 is activated simultaneously, which drives the rotating plate 405 to deflect. The two corresponding limit plates 411 deflect synchronously, which in turn drives the packaging box to deflect synchronously.

[0046] To prevent the packaging box from being further squeezed and deformed during the straightening process, an I-shaped protrusion 412 is fixedly connected to the other side wall of the limiting plate 411. The I-shaped protrusion 412 is slidably connected in the I-shaped groove 410. A compression spring is provided in the I-shaped groove 410. The two ends of the compression spring are fixedly connected to the inner wall of the I-shaped groove 410 and the side wall of the I-shaped protrusion 412, respectively.

[0047] During the deflection of the packaging box, the limiting plate 411 slides relative to the clamping plate 406 and slides synchronously with the deflection of the packaging box, thereby effectively preventing the packaging box from being further squeezed and deformed during the correction process.

[0048] Following the same processing method, the packaging boxes that were blocked in the bending frame 2 were processed one by one until the blockage was completely removed.

[0049] Example 2

[0050] like Figures 1-8 As shown, a support base 7 is provided at the end of a linear frame 1, and a lane changing and separating assembly 3 is provided above the support base 7. The lane changing and separating assembly 3 includes a feeding track 301 and two separating tracks 302. The feeding track 301 and the separating tracks 302 are both provided on the top of the support base 7, and a support frame 8 is fixedly connected to the top of the support base 7.

[0051] The bottom of the support frame 8 is movably connected to the material transfer track 303 via a bearing, and the top of the support frame 8 is movably mounted with an electric push cylinder 304 via a bearing. The top of the material transfer track 303 is fixedly connected to a connecting plate 9, and the output end of the electric push cylinder 304 is rotatably connected to the top of the connecting plate 9.

[0052] When the packaging box gets blocked in the bending frame 2 and is cleared with the help of the unblocking component 4, the surface of the blocked packaging box may be deformed or even cracked due to the pressure caused by the blockage. In order to prevent these defective packaging boxes from flowing into the qualified processing area, the electric push cylinder 304 is activated. The electric push cylinder 304, through its cooperation with the connecting plate 9, drives the transfer track 303 to deflect until the transfer track 303 is connected to another distribution track 302. At this time, these defective packaging boxes flow into the rework area through the distribution track 302 for re-inspection, so that qualified packaging boxes can be put back into the qualified processing area.

[0053] After all the defective packaging boxes have flowed into the rework area, the electric push cylinder 304 will reconnect the transfer track 303 with the corresponding distribution track 302.

[0054] In conjunction with Embodiment 1, the unblocking component 4 can effectively handle and unblock clogged packaging boxes while minimizing damage to the packaging boxes, and, together with the lane changing and separating component 3, enables the directional transport of defective packaging boxes by track and area.
