[0100] To solve the above problems, the embodiments of the present application provide a rule edge banding system, which can simultaneously compatible with the edge banding process of sealing long edge first and sealing short edge first in the case of using a single edge banding machine.

[0101] The technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings.

[0102] Figure 1 is a structural schematic diagram of the rule edge banding system shown in the embodiments of the present application.

[0103] Referring to Figure 1 and Figure 10The application provides a rule edge sealing system, which comprises a feeding mechanism 1, an auxiliary feeding mechanism 2, an edge sealing machine 3, a rotating mechanism 4, a discharging mechanism 5 and a floating milling mechanism 6.

[0104] The feeding mechanism 1 is used for conveying the plate to the auxiliary feeding mechanism 2.

[0105] The auxiliary feeding mechanism 2 is used for adjusting the conveying posture of the plate and comprises a rack 20, a plate conveying line 21, a side pushing device 22, a lower pressing wheel device 23 and two push rod clamping devices 24. The plate conveying line 21 is used for conveying the plate to the edge sealing machine 3. The side pushing device 22 is used for aligning the edge to be sealed of the plate with a feeding reference line of the edge sealing machine 3. The lower pressing wheel device 23 is used for pressing and driving the plate to be close to the direction of the feeding reference line. The push rod clamping device 24 is slidably arranged on the rack 20. The push rod clamping device 24 is provided with a limiting structure and a positioning reference line which is perpendicular to the feeding reference line. The limiting structure is used for keeping the vertical state of the reference edge of the plate by cooperating with the reference edge of another push rod clamping device 24.

[0106] The edge sealing machine 3 is used for sealing the plate.

[0107] The floating milling mechanism 6 is located on one side of the edge sealing machine 3. When the edge sealing machine 3 pre-mills the edge to be sealed of the plate, the floating milling mechanism 6 mills the opposite edge of the plate to be sealed.

[0108] The rotating mechanism 4 is arranged at the discharging end of the edge sealing machine 3 and is used for conveying the plate to the feeding mechanism 1.

[0109] The discharging mechanism 5 is arranged at the discharging end of the rotating mechanism 4 and is used for transferring the plate with four edges sealed.

[0110] The rule edge sealing system provided by the application can be compatible with two kinds of rule edge sealing processes, i.e., sealing the long edge first and then the short edge and sealing the short edge first and then the long edge.

[0111] Specifically, when the rule edge sealing process of sealing the short edge first and then the long edge is performed, the working steps of the auxiliary feeding mechanism 2 can be divided into two steps, i.e., a short edge rule edge sealing process step and a long edge process step. The working process of the short edge rule edge sealing process step is as follows: the plate is conveyed to the auxiliary feeding mechanism 2 through the feeding mechanism 1. The front end of the plate is positioned by the positioning reference line of the two push rod clamping devices 24 close to the feeding mechanism 1, and the plate is flexibly clamped by the limiting structure of the push rod clamping device 24 close to the edge sealing machine 3 and the limiting structure of the push rod clamping device 24 close to the edge sealing machine 3, or the rear end of the plate is positioned by the positioning reference line of the push rod clamping device 24 close to the edge sealing machine 3, and the plate is flexibly clamped by the limiting structure of the push rod clamping device 24 close to the feeding mechanism 1.

[0112] After the positioning reference of the plate is realized by the push rod clamping device 24, the plate can be conveyed to the edge banding machine 3 through the plate conveying line 21. In the process of conveying the plate to the edge banding machine, the one side of the plate is pressed by the lower pressing wheel device 23 to prevent the plate from deviating. The side pushing device 22 pushes the edge to be banded of the plate to move forward along the feeding reference line of the edge banding machine 3 to ensure that the plate is in close contact with the feeding reference line. Under the cooperation of the push rod clamping device 24, the lower pressing wheel device 23 and the side pushing device 22, the plate can enter the edge banding machine in an ideal posture, and the edge banding work is performed in the edge banding machine 3. The banded plate is reversed by 180° through the rotating mechanism 4, and then flows back to the feeding mechanism 1 under the conveying of the rotating mechanism 4 to perform the second short edge banding work. The working procedure of the long edge banding process is as follows: after the edge banding work of the two short edges of the plate is completed, the plate is reversed by 90° through the rotating mechanism 4, and then flows back to the feeding mechanism 1 under the conveying of the rotating mechanism 4, so that one of the long edges to be banded of the plate abuts against the feeding reference line. After the plate enters the auxiliary feeding mechanism 2, since the lengths of the plates are different, the push rod clamping device 24 is in a avoiding state to not participate in the clamping work of the plate, so that the plate can pass through the push rod clamping device 24 to enter the plate conveying line 21. The plate is pressed by the lower pressing wheel device 23 to ensure the stability of the plate, and the side pushing device 22 ensures that the long edge to be banded of the plate can be on the same straight line with the feeding reference line, enters the pre-milling position of the edge banding machine 3, and then performs the pre-milling work of the edge to be banded, and then performs the edge banding treatment. The plate with the first long edge banding is reversed by 180° through the rotating mechanism and flows back to the feeding mechanism 1 to perform the second long edge banding work, and finally is discharged through the discharging mechanism 5.

[0113] In the above-mentioned short edge banding first and then long edge banding process, the auxiliary feeding mechanism 2 keeps the plate in an ideal state before entering the edge banding machine, the floating milling mechanism 6 mills the plate to ensure that the floating milling edge is parallel to the edge to be banded, and the plate flows back through the rotating mechanism 4 after the edge banding machine 3 completes the edge banding work. Compared with manually operating the plate to flow back, the problem of losing the reference edge can be avoided. In addition, the plate can enter the edge banding machine 3 in an ideal posture through the rotating mechanism 4 and the auxiliary feeding mechanism 2, so that the square edge banding system of the application can realize the edge banding work of four edges of the plate with a single edge banding machine 3, which can greatly reduce the equipment cost and labor cost compared with the existing multi-machine connection.

[0114] When the long edge is sealed first, the working process of the auxiliary feeding mechanism can also be divided into two steps, which is opposite to the short edge sealing process. The long edge working process includes the following working process: the plate is conveyed to the auxiliary feeding mechanism 2 by the feeding mechanism 1, at this time the push rod clamping device 24 is in the avoiding state and does not participate in the clamping work of the plate, so that the plate can pass through the push rod clamping device 24 into the plate conveying line 21, the plate is pressed by the lower pressing wheel device 23 to ensure the stability of the plate. Then the side pushing device 22 ensures that the long edge to be sealed of the plate can be located on the same straight line with the feeding reference line, and then the pre-milling work of the long edge to be sealed is carried out in the pre-milling position of the edge sealing machine 3, and then the edge sealing treatment is carried out. The plate with the first long edge sealing is reversed by 180° by the rotating mechanism and flows back to the feeding mechanism 1 to perform the second long edge sealing work, at this time the process of the auxiliary feeding mechanism 2 is the same as that of the first long edge sealing. After the long edge sealing of the plate is completed, the plate is reversed by 90° by the rotating mechanism 4, so that one of the short edges to be sealed of the plate is close to the feeding reference line. After the plate enters the auxiliary feeding mechanism 2, the positioning reference line of the push rod clamping device 24 close to the feeding mechanism 1 positions the front end of the plate, and the limiting structure of the push rod clamping device 24 close to the edge sealing machine 3 cooperates to perform flexible clamping on the plate, or the limiting structure of the push rod clamping device 24 close to the feeding mechanism 1 performs flexible clamping, and the positioning reference line of the push rod clamping device 24 close to the edge sealing machine 3 positions the rear end of the plate. After the positioning reference line of the plate is realized by the push rod clamping device 24, the plate can be conveyed to the edge sealing machine 3 by the plate conveying line 21, and in this process, the plate is pressed by the lower pressing wheel device 23 to prevent the plate from deviating. In the process of conveying the plate, the side pushing device 22 pushes the long edge to be sealed of the plate to move forward along the feeding reference line of the edge sealing machine 3 to ensure that the plate is in close contact with the feeding reference line. The plate is ruled by the cooperation of the push rod clamping device 24, the lower pressing wheel device 23 and the side pushing device 22, and then the ruled plate enters the edge sealing machine 3 to be sealed, and then the sealed plate is reversed by 180° by the rotating mechanism 4 and conveyed to the feeding mechanism 1, and then the second short edge sealing work is continued, and finally the plate is discharged by the discharging mechanism 5.

[0115] In the embodiment, after the plate material enters the auxiliary feeding mechanism 2 through the feeding mechanism 1, the user can select whether to seal the long side first or the short side first according to actual needs. When the short side of the plate material is sealed, the front end of the plate material (i.e., the long side close to the edge sealing machine 3) can be selected as the reference edge, or the rear end of the plate material (i.e., the long side close to the feeding mechanism 1) can be selected as the reference edge. The stability of the plate material in the conveying process is ensured through the lower pressing wheel device 23, and the to-be-sealed edge of the plate material can be aligned with the edge sealing feeding reference line through the side pushing device 22, so that the adjacent two edges are perpendicular or the opposite edges are parallel. After the first short side is sealed, the plate material is reversed by 180°, and the original reference edge can be used as the standard for sealing the second short side, so that the parallelogram and other special-shaped plates are avoided after the reference edge is switched.

[0116] In summary, the auxiliary feeding mechanism 2 ensures that the plate material can enter the edge sealing machine 3 in an ideal posture. In the process of pre-milling of the plate material by the edge sealing machine 3, whether to use floating milling can be selected according to the current process stage of the plate material. The rotation mechanism 4 is used to realize the rotation of the plate material, so that the problem of losing the reference edge in the edge sealing production operation is avoided. The above-mentioned various mechanisms are coordinated to realize the square production of the plate material. The single machine can realize the square edge sealing production process of sealing the short side first or the long side first at the same time. Compared with the prior art, the user can select whether to seal the short side first or the long side first according to actual needs, and the problem of difficult compatibility of edge sealing is solved.

[0179] The second gantry conveying mechanism 44 is used to move the plate located at the return straight roller line 43 to the feeding inclined roller line 12.

[0180] In the embodiment, the first gantry conveying mechanism 42 and the second gantry conveying mechanism 44 each comprise a horizontal moving assembly 421 arranged on a conveying frame, a lifting assembly 422 arranged on the horizontal moving assembly 421, and a rotating suction assembly 423 arranged on the lifting assembly 422, the rotating suction assembly 423 can further comprise a rotating assembly and a suction assembly, the rotating assembly is used to drive the suction assembly to rotate, and the suction assembly is used to move the plate located at the first lifting device and the second lifting device to the return straight roller line 43, wherein the horizontal moving assembly 421 is used to drive the rotating suction assembly 423 to move horizontally, and the lifting assembly 422 is used to drive the rotating suction assembly 423 to move vertically.

[0181] In the embodiment, the roller table 41 is located below the first gantry conveying mechanism 42, and the roller table 41 is provided with a first jacking device (not shown), a sensing device (not shown) for detecting the position of the plate, and a second jacking device (not shown), and the first jacking device and the second jacking device lift the plate based on the position information of the sensing device.

[0183] Figure 24is a structural flow diagram of the rule side edge banding system shown in the embodiments of the present application. Specifically, the workpiece is manually fed by the feeding air floating table 11, and the workpiece is aligned by the feeding inclined roller line 12. The plate is scanned when passing under the scanning device 14, which is not limited to one-dimensional code or two-dimensional code, and the scanning device is installed above and is not limited in angle and number. Then the plate enters the auxiliary feeding mechanism 2, the first mounting plate 204 and the second mounting plate 205 are each installed with 6 sets of push rod assemblies 241 and 6 sets of blocking assemblies 242. The push rod assembly 241 is a combination of a push rod reference edge and a push rod pre-blocking bearing 2428 to flexibly clamp the plate. Along the conveying direction of the plate, the push rod assemblies 241 on the first mounting plate 204 and the second mounting plate 205 serve as reference edges to realize edge banding of the plate. The side pushing device 22 and the pressing wheel device 23 press and align the plate. After the plate enters the pre-milling position of the edge banding machine 3, the floating milling mechanism 6 can mill the un-edged side of the plate according to the actual situation. The plate is edge banded in the intelligent edge banding machine 3, and the edge banding effect of the plate is visually detected by the visual detection mechanism 7, which is not limited to 2D or 3D visual detection of edge banding quality, and finally evaluates the effect. After discharging, the workpiece is collected and processed by the rotating mechanism 4, which can realize single carrying or simultaneous carrying and transfer of multiple plates to the return straight roller line 43 for return processing. If not all edges are completely sealed, the first gantry carrying mechanism 42 and the second gantry carrying mechanism 43 are used for secondary carrying and recycling. If all edges are completely sealed, the plate does not need to be carried by the gantry and returned after passing through the return straight roller line 43, and only needs to be manually discharged by the discharge mechanism 5 (such as a discharge air floating table) at the end of the return straight roller line 43.

[0186] 2. The rule side edge banding system can use the front end of the plate as a reference or use the rear end of the plate as a reference when producing the plate, which can meet different alignment references and ensure the production accuracy of the rule side edge banding system.

[0187] 3. The feed edge (i.e., baseline) of the edge banding machine 3 is adjusted to accommodate different pre-milling requirements. The designed side pusher 22 automatically adjusts to this baseline, ensuring that the board's edge to be banded is aligned with the feed baseline of the edge banding machine 3 without requiring manual adjustments to related structures or parameters, achieving an automatic docking effect. The side pusher 22 also includes a side push fine-tuning assembly 2204, which allows for electric fine-tuning. The terminal utilizes a contact displacement sensor 22045 for high-precision control and ease of use, effectively improving production efficiency.

[0188] 4. The plates are classified and collected through the roller table 41, the first gantry conveying mechanism 42 and the second gantry conveying mechanism 43. For plates of different sizes, the first gantry conveying mechanism 42 can take one or two plates at the same time in conjunction with the lifting device on the roller table 41, thereby realizing the collection and transportation of the plates and maximizing the efficiency of the production line.
