Description

Technical Field

[0001] The present invention relates to the technical field of plate edge banding, and particularly relates to a vision-based anti-offset plate edge banding reflux conveying device. Background Art

[0002] A plate edge banding machine is a special device for edge banding the edges of plates (such as particle boards, density boards, ecological boards, etc.). It attaches edge banding materials (PVC, ABS, wood veneer, etc.) to the edges of the plates to play a role in protection, decoration, and moisture prevention, and is widely used in fields such as furniture manufacturing and woodworking processing. Existing plate edge banding machines can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] Patent document CN118024365A discloses a plate edge banding machine on the publication date of May 14, 2024, which includes a conveying box. On one side of the conveying box, a polishing box, a gluing box, a tape feeding box, a trimming box, and a grinding box are sequentially spliced and installed. At both ends on the other side of the conveying box, support frames are installed. At the top of the support frames, support slide rails are installed. Between the two support frames, a conveyor belt is jointly installed. There is a gap between the belt surface of the conveyor belt and the support frames. On the two support slide rails, a first roller belt, a second roller belt, and a third roller belt are jointly provided. In the middle of the inner side wall of the tape feeding box, a deflection sleeve is installed. On one side of the deflection sleeve, a support shaft is provided. On the inner side wall of the tape feeding box and on the other side of the deflection sleeve, a through hole is opened. A slitting mechanism is installed in the through hole. Between the deflection sleeve and the through hole, an adjustment box is provided. There are two support shafts, and a sealing tape holder is movably sleeved on the support shafts, which can replace the empty sealing tape holder during the continuous edge banding operation, and improve the overall processing efficiency and processing automation rate by changing the tape without stopping the machine.

[0004] In actual use, usually two opposite edges of the plate need to be edge banded. The plate can only complete the edge banding on one side when passing through the edge banding machine once, and workers still need to move the plate back to the starting position of the edge banding machine to perform the edge banding on the other side. Therefore, there is an urgent need for a vision-based anti-offset plate edge banding reflux conveying device to solve the above problems. Summary of the Invention

Detailed implementation manners

[0031] To make the purpose, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-7, A vision-based anti-offset sheet edge-sealing and reflux conveying device provided by an embodiment of the present invention includes a machine compartment 1 and a rolling belt 2 arranged on one side of the machine compartment 1. A vision unit 33 corresponding to the upper side of the rolling belt 2 is also suspended on the machine compartment 1. The vision unit 33 is used for monitoring the offset of the sheets conveyed on the rolling belt 2. It further includes: a panel 3, which is uniformly arranged in a plurality along the circumferential direction of the rolling belt 2 on the outer side of the rolling belt 2, and is movably arranged along the axial direction of the support shaft of the rolling belt 2. It has a first state of contracting and approaching the machine compartment 1 on the upper side of the rolling belt 2 and a second state of extending and moving away from the machine compartment 1 on the lower side of the rolling belt 2; a first roller frame 4, which is arranged in parallel on the outer side of the rolling belt 2 and cooperates with the continuous panel 3 to stably support the sheets; a pushing component, which is arranged corresponding to the conveying end on the upper side of the rolling belt 2 and is used to push one end of the target sheet away from the panel 3 on the upper side of the rolling belt 2 and onto the panel 3 on the lower side of the rolling belt 2.

[0033] Specifically, the machine chamber 1 is used to receive the board and edge-seal it; preferably, there are multiple vision units 33, which are evenly arranged along the conveying direction of the rolling belt 2, and the vision unit 33 includes an industrial wide-angle camera to ensure complete monitoring of the rolling belt 2; the vision unit 33 is linked to the servo system that controls the operation of the rolling belt 2. Through vision measurement and under the comparison of the system, the vision unit 33 observes the boundary position of the board on the rolling belt 2. When the board deviates and moves out of the machine chamber 1, that is, under normal circumstances, one side of the board remains inside the machine chamber 1 for edge-sealing. When the side of the board close to the machine chamber 1 appears in the vision detection image of the vision unit 33, it means that the board cannot be edge-sealed normally. Thus, the vision unit 33 feeds back and triggers the servo system. The servo system then controls the rolling belt 2 to stop and alarms, reminding that the equipment needs to be repaired or cleaned, or there may be defects in the board; the rolling belt 2 is used to drive multiple continuously arranged panels 3 on it to roll in a cycle, and the rolling direction on the upper side of the rolling belt 2 is the same as the direction of edge-sealing in the machine chamber 1; the panel 3 is preferably in the shape of a rectangular plate, and there is a gap between two adjacent panels 3; the movement of the panel 3 is used to switch states; the panel 3 alternately lies on the upper and lower sides of the rolling belt 2 as the rolling belt 2 rolls, corresponding to the panel 3 being in the first state and the second state; the support height of the first roller rack 4 is preferably flush with the upper surface of the panel 3 rolling on the upper side of the rolling belt 2; the first roller rack 4 is fixedly arranged relative to the machine chamber 1; the pushing component pushes along the axial direction of the support shaft of the rolling belt 2; the side of the panel 3 facing the rolling belt 2 is rough or provided with damping lines to generate greater friction when contacting the board; one end of the board pushed away from the upper-side panel 3 of the rolling belt 2 falls onto the lower-side panel 3 of the rolling belt 2, while the other end is still supported on the first roller rack 4, thereby tilting the board. At this time, the board is easily driven by the lower-side panel 3. In actual use, after the board moves above the rolling belt 2 for one-side edge-sealing, at the conveying end of the rolling belt 2, the board is pushed away from the upper-side panel 3 in the first state of the rolling belt 2 under the action of the pushing component and falls onto the lower-side panel 3 in the second state of the rolling belt 2. The first roller rack 4 then keeps supporting the other end of the board. Thus, the lower-side panel 3 in the second state of the rolling belt 2 can drive the board with one side edge-sealed to move in the reverse direction, realizing the automatic return of the board to the edge-sealing start end and eliminating manual handling.

[0034] Compared with the prior art, a vision-based anti-offset board edge-sealing and return conveying device proposed in an embodiment of the present invention realizes the automatic return of the board to the edge-sealing start end and eliminates manual handling by setting movable panels 3 on the rolling belt 2. After the board moves above the rolling belt 2 for one-side edge-sealing, at the conveying end of the rolling belt 2, the board is pushed away from the upper-side panel 3 in the first state of the rolling belt 2 under the action of the pushing component and falls onto the lower-side panel 3 in the second state of the rolling belt 2. The first roller rack 4 then keeps supporting the other end of the board. Thus, the lower-side panel 3 in the second state of the rolling belt 2 can drive the board with one side edge-sealed to move in the reverse direction, improving the practicability of the device.

[0035] As a preferred technical solution of this embodiment, a guide sleeve 5 is fixedly arranged on the outer wall of the rolling belt 2, a guide post 6 movably connected to the guide sleeve 5 is fixedly arranged on the panel 3, connecting pieces 7 are arranged at both ends of the guide post 6 and connected to the panel 3, a first elastic member 8 is arranged between one of the connecting pieces 7 and one end of the guide sleeve 5, and a guiding assembly for changing the state of the panel 3 is arranged on the side wall of the machine chamber 1. Specifically, the guide sleeve 5 is arranged along the axial direction of the support shaft of the rolling belt 2; the length of the guide post 6 is set to be greater than the length of the guide sleeve 5; a set of convex ribs are arranged on both opposite sides of the guide sleeve 5 on the outer wall of the rolling belt 2 to support the panel 3, so that the panel 3 remains horizontal on the upper and lower sides of the rolling belt 2; the first elastic member 8 is preferably a spring and is sleeved on the guide post 6. The setting of the first elastic member 8 keeps the connecting piece 7 close to the machine chamber 1, that is, makes the panel 3 automatically remain in the first state; the guiding assembly is arranged corresponding to the lower side of the rolling belt 2 and is used to guide the panel 3 to switch from the first state to the second state. When the panel 3 gets out of the range where the guiding assembly is arranged, the panel 3 automatically switches back to the first state under the action of the first elastic member 8.

[0036] As a further preferred technical solution of this embodiment, the guiding assembly includes an arc-shaped guiding platform 9 and a convex platform 10 fixedly arranged on the side wall of the machine chamber 1. The arc-shaped guiding platform 9 is arranged such that the length protruding from the side wall of the machine chamber 1 gradually increases from the upper end to the lower end. The convex platform 10 is parallel to the lower side of the rolling belt 2 and is connected to the lower end of the arc-shaped guiding platform 9. A sliding pin 11 is fixedly arranged at one end of the panel 3 close to the machine chamber 1. Specifically, the center of the arc-shaped guiding platform 9 coincides with the axial direction of the support shaft corresponding to the upper conveying end of the rolling belt 2; the length of the convex platform 10 protruding from the side wall of the machine chamber 1 is uniformly set; the moving track of the sliding pin 11 following the panel 3 and then the rolling belt 2 corresponds to the arrangement tracks of the arc-shaped guiding platform 9 and the convex platform 10; at the conveying end of the rolling belt 2, the sliding pin 11 on the panel 3 contacts the arc-shaped guiding platform 9, and then, driven by the rolling belt 2, the panel 3 gradually switches from the first state to the second state. When the sliding pin 11 passes through the lower end of the arc-shaped guiding platform 9, that is, the connection part of the arc-shaped guiding platform 9 and the convex platform 10, the panel 3 switches to the second state. When the sliding pin 11 continuously passes through the convex platform 10, the panel 3 maintains the second state. The position where the sliding pin 11 disengages from the convex platform 10 is arranged close to the lower conveying end of the rolling belt 2; a return tray is arranged on the side wall of the machine chamber 1 corresponding to the position where the sliding pin 11 disengages from the convex platform 10 for receiving the returned plates.

[0037] As a preferred technical solution of this embodiment, a partition plate 12 fixedly connected to the machine chamber 1 is provided on one side of the rolling belt 2 away from the machine chamber 1. At both ends of the upper side of the partition plate 12, there are support plates 13 connecting the two ends of the rolling belt 2. Specifically, the partition plate 12 is provided to facilitate the sliding of one end of the plate falling on the lower panel 3, preventing it from being embedded inside the rolling belt 2; the height of the lower end of the partition plate 12 corresponds to the upper surface of the lower panel 3; a part of the conveying end of the rolling belt 2 is inclined downward, thus being lower than the corresponding support plate 13 on this side, and the side of the rotating part of the conveying end of the rolling belt 2 away from the machine chamber 1 is not blocked by the partition plate 12, thus not hindering the switching of the state of the panel 3; the plate conveyed on the upper side of the rolling belt 2 can automatically slide above the support plate 13 on this side, and the pushing component pushes the plate above the support plate 13 on this side.

[0038] As a preferred technical solution of this embodiment, the pushing component includes a push plate 14 movably connected to the side wall of the machine chamber 1, and a telescopic driving unit 15 for driving the movement of the push plate 14 is arranged in the machine chamber 1. Specifically, the telescopic driving unit 15 is controlled by a servo system. After the plate lands on the support plate 13 corresponding to the conveying end of the rolling belt 2, the telescopic driving unit 15 is controlled to start, driving the push plate 14 to push the plate above the support plate 13 and automatically retracting. The driving direction of the telescopic driving unit 15 for the push plate 14 is arranged parallel to the axial direction of the support shaft of the rolling belt 2.

[0039] In the way of the plate reflux adopted in the above embodiment, one end of the plate is always supported on the first roller rack 4. Thus, both the edge sealing and the reflux of the plate will occupy the first roller rack 4, resulting in only single plate edge sealing and reflux being possible each time, affecting the production efficiency. The following embodiment is proposed to solve this problem.

[0040] In another embodiment proposed by the present invention, a second roller rack 16 is arranged in parallel and at intervals on the lower side of the first roller rack 4. A support 17 is arranged on the machine chamber 1. A third roller rack 18 which can be lifted and switched to connect the first roller rack 4 and the second roller rack 16 is arranged on the support 17 in a lifting manner. A linkage component for linking the movement of the push plate 14 and the lifting of the third roller rack 18 is arranged on the machine chamber 1. When the push plate 14 pushes the target plate away from the panel 3 on the upper side of the rolling belt 2, the linkage component is triggered to drive the third roller rack 18 to descend so as to switch from the position corresponding to connecting the first roller rack 4 to the position corresponding to connecting the second roller rack 16. Specifically, for the rollers on the second roller rack 16 and the third roller rack 18, the outer diameter of the end close to the machine chamber 1 gradually decreases to form a conical shape, thereby facilitating the auxiliary movement of the plate inclinedly supported thereon; the support 17 extends horizontally outward perpendicular to the side surface of the machine chamber 1, the height of the support 17 is lower than that of the rolling belt 2, and it is arranged corresponding to the upper conveying end of the rolling belt 2; the third roller rack 18 is collinearly connected with the first roller rack 4 or the second roller rack 16 through lifting; the third roller rack 18 is arranged corresponding to the support plate 13 on the upper conveying end of the rolling belt 2 in the side direction of the machine chamber 1; the linkage component is semi-triggered. When the push plate 14 pushes the target plate away from the panel 3 on the upper side of the rolling belt 2, the linkage component is triggered to drive the third roller rack 18 to descend, and during the retraction process of the push plate 14, the linkage component drives the third roller rack 18 to rise and reset synchronously. In this way, it can be ensured that when the push plate 14 pushes the plate, the third roller rack 18 will not descend to cause the plate to slide outwards. In the actual use of this technical solution, after one side of the plate is edge-sealed, it is sent onto the corresponding support plate 13 and the third roller rack 18 at the conveying end of the rolling belt 2. At this time, the third roller rack 18 is just connected to the first roller rack 4. Then, the pushing component pushes the plate away from the support plate 13, and then the linkage component is triggered to drive the third roller rack 18 to descend so as to switch and connect to the second roller rack 16. At this time, one end of the plate is supported on the panel 3 in the second state on the lower side of the rolling belt 2, and the other end is supported on the third roller rack 18 with a decreased height. Thus, the plate is driven by the panel 3 in the second state driven by the rolling belt 2 and undergoes a reflux movement, leaves the third roller rack 18, climbs onto the second roller rack 16 and continues to move, so that the plates for edge-sealing and the plates for reflux move in layers, ensuring that multiple plates can be edge-sealed or refluxed synchronously, and improving the production efficiency.

[0041] As a preferred technical solution of this embodiment, the linkage assembly includes a sleeve 19 rotatably arranged on a support 17. A telescopic column 20 connected to the third roller frame 18 is telescopically and movably arranged at the upper end of the sleeve 19. A top column 21 is axially movably arranged in the telescopic column 20. A transmission block 22 threadedly connected to the inner wall of the sleeve 19 is coaxially connected to the lower end of the top column 21. The sleeve 19 is connected to a transmission shaft 23 through a belt pulley. A linkage gear 24 is coaxially connected to the upper end of the transmission shaft 23. The linkage gear 24 is meshed with a linkage rack 25 fixedly connected to the push plate 14. A limiting assembly for limiting the downward movement of the third roller frame 18 is arranged on the support 17. The limiting assembly cancels the limit when the push plate 14 pushes the target plate away from the panel 3 on the upper side of the rolling belt 2. Specifically, the sleeve 19 is vertically arranged, and the telescopic column 20 movably penetrates through the upper end of the sleeve 19, while the lower end of the telescopic column 20 is limited within the sleeve 19. The top column 21 is preferably polygonal prism-shaped and only moves up and down relative to the telescopic column 20. Thus, when the sleeve 19 rotates, a thread feeding effect will occur with the transmission block 22. The transmission shaft 23 is rotatably arranged in the machine chamber 1 and is connected to the sleeve 19 through a belt pulley at the lower end. The movement of the push plate 14 drives the movement of the linkage rack 25. The linkage rack 25 drives the transmission shaft 23 to rotate through the linkage gear 24. The transmission shaft 23 drives the sleeve 19 to rotate through a belt pulley. The sleeve 19 has a thread feeding effect with the transmission block 22 to cause the top column 21 to move up and down, and the telescopic column 20 moves up and down with the top column 21 under the action of gravity. The limit of the limiting assembly on the third roller frame 18 is used to delay the linkage of the pushing movement of the push plate 14 to the downward movement of the third roller frame 18, ensuring that the third roller frame 18 only descends after the push plate 14 pushes the plate away from the panel 3 on the upper side of the rolling belt 2, that is, preventing the plate from slipping outwards.

[0042] As a preferred technical solution of this embodiment, the limiting component includes a column 26 fixedly arranged on the support 17 and a sleeve 27 fixedly arranged at the bottom of the third roller frame 18 and matching with the column 26. A rotating chamber 28 is arranged on the sleeve 27. A rotating block 29 is elastically rotatably arranged in the rotating chamber 28. A through hole 30 matching with the column 26 is arranged on the rotating block 29. An inclined upward warping rod 31 is fixedly arranged on the side wall of the rotating block 29. Specifically, the column 26 is axially parallel to the sleeve 27; the upper end of the column 26 is inserted into the sleeve 27; a torsion spring connecting the rotating shaft of the rotating block 29 is arranged inside the rotating chamber 28; due to the elastic rotation function of the rotating block 29, in its free state, the through hole 30 inside it keeps misaligned with the hollow of the sleeve 27; when the third roller frame 18 is at the highest position of the lifting stroke and correspondingly connects with the first roller frame 4, the upper end of the column 26 corresponds to the lower side of the rotating block 29; the warping rod 31 is arranged on the rotating block 29 close to one side of the machine chamber 1, and the upper end of the warping rod 31 inclines and approaches the machine chamber 1 side; when the plate is pushed away from the panel 3 on the upper side of the rolling belt 2, this end of the plate freely falls and tilts. Therefore, the bottom surface of the plate can press down the upper end of the warping rod 31 to trigger the rotation of the rotating block 29, so that the through hole 30 gradually corresponds vertically to the hollow of the sleeve 27, and then the column 26 can pass through the through hole 30 to penetrate into the sleeve 27, that is, the third roller frame 18 can be triggered to descend; after the plate subsequently flows back and leaves the third roller frame 18, the push plate 14 retracts, and then the linkage push rod 21 rises, the push rod 21 drives the telescopic column 20 to rise, that is, the third roller frame 18 rises, and the column 26 also descends relative to the sleeve 27 until the third roller frame 18 rises to the highest position to reconnect with the first roller frame 4, and the column 26 also disengages from the through hole 30, and the rotating block 29 rotates and resets under the elastic force so that the through hole 30 is misaligned with the hollow of the sleeve 27 again.

[0043] As a preferred technical solution of this embodiment, a second elastic member 32 is connected between the lower end of the telescopic column 20 and the transmission block 22. Specifically, the second elastic member 32 can preferably be a spring, sleeved outside the push rod 21, and connecting the telescopic column 20 and the transmission block 22, so that when the transmission block 22 moves downward and the limiting component is not triggered to cancel the limit, the second elastic member 32 is stretched and stores elastic potential energy, ensuring that when the limiting component is triggered to cancel the limit subsequently, the second elastic member 32 releases the elastic potential energy and contracts, so that the telescopic column 20 can descend smoothly, and when approaching the lowest position during the descent, the second elastic member 32 can also buffer the descent of the telescopic column 20.

[0044] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
