[0102] In response to the above problems, an embodiment of the present application provides a square edge banding system, which can be compatible with both the long edge sealing first and the short edge sealing first edge banding processes when using a single edge banding machine.

[0103] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0104] Figure 1 It is a schematic structural diagram of the square edge banding system shown in an embodiment of the present application.

[0105] See also Figure 1 and Fig.10 , a square edge banding system provided in an embodiment of the present application includes a feeding mechanism 1, an auxiliary feeding mechanism 2, an edge banding machine 3, a rotating mechanism 4, a feeding mechanism 5 and a floating milling mechanism 6;

[0106] The feeding mechanism 1 is used to convey the plate to the auxiliary feeding mechanism 2;

[0107] The auxiliary feeding mechanism 2 is used to adjust the conveying posture of the plate, and includes a frame 20, a plate conveying line 21, a side push device 22, a lower pressure wheel device 23 and two push rod clamping devices 24. The plate conveying line 21 is used to convey the plate to the edge banding machine 3. The side push device 22 is used to align the edge of the plate to be banded with the feed reference line of the edge banding machine 3. The lower pressure wheel device 23 is used to press and drive the plate toward the direction of the feed reference line. The push rod clamping device 24 is slidably arranged on the frame 20. The push rod clamping device 24 has a limiting structure and a positioning reference line perpendicular to the feed reference line. The limiting structure is used to maintain the vertical state of the reference edge of the plate by cooperating with the reference edge of another push rod clamping device 24.

[0108] The edge banding machine 3 is used to perform edge banding on the plate;

[0109] The floating milling mechanism 6 is located on one side of the edge banding machine 3. When the edge banding machine 3 performs pre-milling on the edge to be banded of the plate, the floating milling mechanism 6 performs floating milling on the opposite edge of the plate to be banded.

[0110] The rotary mechanism 4 is disposed at the discharge end of the edge banding machine 3 and is used to transport the plate to the feeding mechanism 1;

[0111] The unloading mechanism 5 is arranged at the discharging end of the rotary mechanism 4 and is used for transferring the plate with four edges sealed.

[0112] The square edge banding system provided in the embodiment of the present application is compatible with two square edge banding processes: first long edge banding and then short edge banding, and first short edge banding and then long edge banding.

[0113] Specifically, when the short edge is sealed first and then the long edge is sealed, the working steps of the auxiliary feeding mechanism 2 can be divided into two steps, the short edge squaring process step and the long edge process step. The working process of the short edge squaring process step is as follows: the plate is transported to the auxiliary feeding mechanism 2 by the feeding mechanism 1, and the positioning reference lines of the two push rod clamping devices 24 close to the feeding mechanism 1 are used to position the front end of the plate, and the plate is flexibly clamped together with the limiting structure of the push rod clamping device 24 close to the edge banding machine 3, or the positioning reference line of the push rod clamping device 24 close to the edge banding machine 3 is used to position the rear end of the plate, and the limiting structure of the push rod clamping device 24 close to the feeding mechanism 1 is used to flexibly clamp the plate.

[0114] After the plate is positioned at the reference position by the push rod clamping device 24, the plate can be transported to the edge banding machine 3 by the plate conveying line 21. In the process of transporting the plate to the edge banding machine, the lower pressure wheel device 23 presses one side of the plate to prevent the plate from running off the edge; the side push device 22 pushes the plate to be edge banded forward along the feed reference line of the edge banding machine 3 to ensure that the plate is in close contact with the feed reference line. With the cooperation of the push rod clamping device 24, the lower pressure wheel device 23 and the side push 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 edge banded plate is reversed 180° by the rotating mechanism 4, and then returned to the feeding mechanism 1 under the transportation of the rotating mechanism 4 to perform the second short edge banding work. The workflow of the long edge square banding process is as follows: after completing the banding of the two short edges of the plate, the plate is reversed by 90° through the rotary mechanism 4, and then flows back to the feeding mechanism 1 under the conveyance of the rotary mechanism 4, so that one of the long edges of the plate to be sealed abuts against the feed reference line. After the plate enters the auxiliary feeding mechanism 2, due to the different lengths of the plates, for the convenience of operation, the push rod clamping device 24 is in an avoidance state at this time, and does not participate in the clamping work of the plate, so that the plate can pass the push rod clamping device 24 and enter the plate conveying line 21. The plate is pressed by the lower pressing wheel device 23 to ensure the stability of the plate. The side push device 22 ensures that the long edge of the plate to be sealed can be on the same straight line as the feed reference line. After entering the pre-milling station of the edge banding machine 3, the pre-milling work of the edge to be sealed is carried out, and then the edge banding process is carried out. The plate that completes the first long edge banding is reversed by 180° through the rotary mechanism and flows back to the feeding mechanism 1, and the second long edge banding work is performed, and finally the material is discharged through the unloading mechanism 5.

[0115] In the above-mentioned squaring edge banding process of sealing the short edge first and then the long edge, the auxiliary feeding mechanism 2 is used to maintain the ideal state of the plate before entering the edge banding, and the floating milling mechanism 6 is used to perform floating milling on the plate, thereby ensuring that the floating milled edge can be parallel to the edge to be banded, so as to achieve squaring correction. After the edge banding machine 3 completes the edge banding work, the swivel mechanism 4 is used to realize the reflux work of the plate, which can avoid the problem of losing the reference edge compared to the manual operation of the plate reflux. In addition, the swivel mechanism 4 realizes the rotation of the plate and the auxiliary feeding mechanism 2 is used to keep the plate in an ideal posture to enter the edge banding machine 3, so that the swivel edge banding system of the present application can realize the edge banding work of the four edges of the plate with a single edge banding machine 3, which can greatly reduce the equipment cost and labor cost compared to the existing multi-machine connection.

[0116] When sealing the long side first and then the short side, the work flow of the auxiliary feeding mechanism can also be divided into two steps, which is opposite to the process order of sealing the short side first. The long side process step includes the following work flow: 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 an avoidance state and does not participate in the clamping work of the plate, so that the plate can pass the push rod clamping device 24 and enter 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 push device 22 is used to ensure that the long side to be sealed of the plate can be located on the same straight line as the feed reference line. After entering the pre-milling station of the edge banding machine 3, the pre-milling work of the edge to be sealed is carried out, and then the edge banding process is carried out. The plate that has completed the first long edge banding is reversed by 180° through the rotary mechanism and refluxed to the feeding mechanism 1 to perform the second long edge banding work. At this time, the process of the auxiliary feeding mechanism 2 is the same as the process when the first long edge is banded. After the long edge of the plate is sealed, the plate is transferred by 90° through the rotary mechanism 4, so that one of the short edges to be sealed of the plate is close to the feed 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 is used to position the front end of the plate, and the plate is flexibly clamped together with the limiting structure of the push rod clamping device 24 close to the edge banding machine 3, or the limiting structure of the push rod clamping device 24 close to the feeding mechanism 1 is used to flexibly clamp the plate, and the positioning reference line of the push rod clamping device 24 close to the edge banding machine 3 is used to position the rear end of the plate. After the positioning reference of the plate is achieved by the push rod clamping device 24, the plate can be transported to the edge banding machine 3 through the plate conveying line 21. During this process, the lower pressing wheel device 23 presses the plate to prevent the plate from running off. During the conveying of the plate, the side push device 22 pushes the edge to be sealed of the plate forward along the feed reference line of the edge banding machine 3 to ensure that the plate is in close contact with the feed reference line. The push rod clamping device 24, the lower pressure wheel device 23 and the side push device 22 cooperate to realize the squaring of the plate, and the squared plate enters the edge banding machine 3 for edge banding. The edge banded plate is transferred to the feeding mechanism 1 by 180° reversal through the rotating mechanism 4, and then the second short side edge banding work is continued, and finally the plate is discharged through the unloading mechanism 5.

[0117] In this embodiment, after the sheet enters the auxiliary feeding mechanism 2 through the feeding mechanism 1, the user can choose to seal the long side or the short side first according to actual needs. When sealing the short side of the sheet, the front end of the sheet (i.e., the long side close to the edge banding machine 3) can be selected as the reference side, or the rear end of the sheet (i.e., the long side close to the feeding mechanism 1) can be selected as the reference side. The stability of the sheet during transportation is ensured by the lower pressure wheel device 23, and the side push device 22 is used to ensure that the edge to be sealed of the sheet can be aligned with the edge sealing feed reference line to achieve the effect of verticality of adjacent sides or parallelity of opposite sides. After completing the edge sealing of the first short side, the sheet can be reversed by 180°, and the original reference side can be used as the standard for the second short side edge sealing, avoiding the appearance of special shapes such as parallelograms on the sheet due to switching the reference side.

[0118] To summarize, the present application uses the auxiliary material mechanism 2 to ensure that the plate can enter the edge banding machine 3 in an ideal posture. During the pre-milling of the plate by the edge banding machine 3, it can be selected whether to enable floating milling according to the current process stage of the plate, and the plate is rotated by the rotating mechanism 4 to ensure that the reference edge is not lost during the edge banding production operation. The square production of the plate is realized through the coordination of the above-mentioned mechanisms, and the square edge banding production process of sealing the short edge first or the long edge first can be realized with a single machine connection. Compared with the existing technology, it is convenient for users to choose whether to seal the short edge first or the long edge first according to actual needs, which solves the problem of difficult compatibility of edge banding.

[0121] The push rod base 2411 has a first end and a second end arranged in the same direction, the first end is provided with a push rod bearing seat 2417, and the second end is hinged to the push rod cylinder 2415; the push rod bearing seat 2417 is provided with a bearing, the push rod mounting plate 2413 is rotatably connected to the bearing through a rotating shaft, the conveying shaft of the push rod cylinder 2415 is hinged to the push rod mounting plate 2413, and the push rod mounting plate 2413 is provided with a push plate 2418 at one end away from the bearing seat, and the push plate 2418 is used to abut against the side of the plate;

[0124] The first exhaust throttle valve 2416 is connected to the push rod cylinder 2415 and is used to adjust the air pressure value of the push rod cylinder 2415.

[0125] For further information, see Figures 8 to 10 The blocking assembly 242 includes a blocking base 2421, a blocking positioning screw 2422, a blocking mounting plate 2423, a blocking cylinder 2424, a photoelectric sensor 2425 and a second exhaust throttle valve 2426;

[0127] The blocking positioning screw 2422 is threadedly matched with the blocking bearing seat 2427, and the end of the blocking positioning screw 22043 is opposite to the blocking mounting plate 2423;

[0128] The photoelectric sensor 2425 is located below the blocking bearing seat 2427 and is used to sense the tilt state of the plate;

[0129] The second exhaust throttle valve 2426 is connected to the blocking cylinder 2424 and is used to adjust the air pressure value of the blocking cylinder 2424.

[0130] In this embodiment, along the conveying direction of the plate, the first mounting plate 204 is close to the feeding mechanism 1, and the second mounting plate 205 is close to the edge sealing. The first mounting plate 204 and the second mounting plate 205 are both provided with six sets of push rod assemblies 241 and six sets of blocking assemblies 242 to realize the front reference or rear reference of the plate. By using the push rod assemblies 241 and blocking assemblies 242 in the front and rear directions, it is ensured that the plate can keep the reference edge unchanged after the reversal, thereby solving the problem in the prior art that the short side is sealed first and it is difficult to solve the square. In specific implementation, the push rod assemblies 241 and blocking assemblies 242 of the grids on the first mounting plate 204 and the second mounting plate 205 are adjusted to a straight line to ensure the stability of the flexible clamping, and the straight line is perpendicular to the feed reference line.

[0131] Specifically, the first transmission part 202 and the second transmission part 203 both include a synchronous belt, a transmission wheel and a motor. The first mounting plate 204 and the second mounting plate 205 are respectively connected to a synchronous belt and slide on the frame 20 through the linear guide rail 201. The first mounting plate 204 and the second mounting plate 205 are independent of each other. When clamping plates of different sizes, the distance between the first mounting plate 204 and the second mounting plate 205 is adjusted through motor transmission to adapt to the current size of the plate.

[0132] In addition, in order to avoid mutual collision between the first mounting plate 204 and the second mounting plate 205, a second anti-collision block 207 is also designed on the second mounting plate 205, and a first anti-collision block 206 is provided in the front and rear directions of the rack 20 to avoid the first mounting plate 204 or the second mounting plate 205 from being limited and collided. Furthermore, the rack 20 is also provided with a drag chain and a drag chain wire board, and the drag chain is installed on the drag chain wire board and is connected to the first mounting plate 204 and the second mounting plate 205 respectively to realize the connection of the circuit and the gas path.

[0133] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, Figure 6 is a schematic diagram of the extended state of the push rod assembly 241 shown in the embodiment of the present application; Figure 7 is a schematic diagram of the retracted state of the push rod assembly 241 shown in the embodiment of the present application; Fig. 9 is a schematic diagram of the extended state of the blocking assembly 242 shown in the embodiment of the present application; Fig.10 It is a schematic diagram of the retracted state of the blocking assembly 242 shown in the embodiment of the present application.

[0134] After the sheet arrives at the auxiliary feeding mechanism 2, the push rod assembly 241 and the blocking assembly 242 on the first mounting plate 204 are both in a retracted state, so that the sheet can enter the sheet conveying line 21. After the sheet enters the sheet conveying line 21, the push rod assembly 241 on the first mounting plate 204 or the push rod assembly 241 on the second mounting plate 205 extends according to the reference edge of the current sheet. When the push rod assembly 241 on the first mounting plate 204 extends, the blocking assembly 242 on the second mounting plate 205 extends, which is the front reference; when the push rod assembly 241 on the second mounting plate 205 extends, the blocking assembly 242 of the first mounting plate 204 extends, which is the rear reference. After the push rod assembly 241 and the blocking assembly 242 clamp and fix the sheet, the first mounting plate 204 and the second mounting plate 205 are driven to move on the frame 20 through the first transmission part 202 and the second transmission part 203, so as to convey the sheet to the pre-milling station of the edge banding machine 3. When the second mounting plate 205 moves to the extreme position, the push rod assembly 241 or the blocking assembly 242 on the second mounting plate 205 executes a retraction control instruction, so that the plate can smoothly enter the edge banding machine 3 .

[0135] During the operation of the square edge banding system, the push rod mounting plate 2413 of the push rod assembly 241 can adjust the rotation range through the push rod positioning screw 2412, and adjust the distance between the push plate 2418 and the push rod mounting plate 2413 through the adjusting screw 2414, and then fine-tune the push plates 2418 in each push rod assembly 241, so that the push plates 2418 of each push rod assembly 241 can be located on the same horizontal plane, and the blocking bearing 2428 is installed on the blocking mounting plate 2423. When the cylinder is retracted, the retraction amount can be adjusted through the blocking positioning screw 2422. The photoelectric sensor 2425 is installed on the blocking base 2421. When the plate is not in a straight line with the pusher due to an error, the photoelectric sensor 2425 will sense the tilted state of the plate and perform alarm processing to prevent accidents before the plate enters the edge banding machine 3.

[0136] In this embodiment, the auxiliary feeding mechanism 2 can use the front end of the plate as a reference, or the rear end of the plate as a reference, and the blocking component 242 realizes flexible clamping under the joint action of the blocking bearing 2428 clamping plate and the push plate 2418. In the clamped state, the blocking cylinder 2424 is subjected to force, and acts like a spring. When used in conjunction with the push plate 2418 as a reference, the other end plays a role of elastic and flexible clamping to achieve a squaring effect.

The side thrust fine-tuning assembly 2204 is disposed on the frame 20. The side thrust fine-tuning assembly 2204 is used to drive the side thrust main board 2207 to move so as to adjust the relative position of the side thrust bearing 2200 and the feed reference line.

The mounting seat of the floating joint 2213 is arranged on the side thrust unit plate 2209 and is clamped with the floating joint 2213.

[0144] The purpose of the side thrust device 22 is to fine-tune the side thrust edge (i.e., the edge to be sealed) of the plate outward before the plate enters the edge banding machine 3, so that when the plate enters the edge banding machine 3, it can be located on the same straight line as the feed reference line of the edge banding machine 3, ensuring that the plate can smoothly enter the edge banding machine 3 and achieve a regular edge banding effect. In order to ensure the flexible adjustment of the plate in the auxiliary feeding mechanism 2 and improve the working accuracy of the side thrust device 22, the side thrust device 22 is provided with four sets of side thrust unit plates 2209, which are installed on the side thrust straightening plate 2201 by bolts, and a number of side thrust bearings 2200 are installed at the front end of the side thrust straightening plate 2201, and the number of side thrust bearings 2200 are in contact with the plate, and each side thrust bearing 2200 is in contact with the plate to form a straight line, which coincides with the feed reference line. The distance between the side thrust straightening plate 2201 and the side thrust unit plate 2209 can be adjusted through the arc hole on the side thrust straightening plate 2201, and the side thrust straightening plate 2201 can be locked by bolts. In addition, in order to improve the portability of debugging the side thrust device 22, the side thrust straightening plate 2201 can also be tightened by the straightening seat 2202 and the straightening screw 2203 to fine-tune the distance between the side thrust straightening plate 2201 and the side thrust unit plate 2209. With the coordination of the bolts and the arc hole and the coordination of the straightening seat 2202 and the straightening screw 2203, it can be ensured to the greatest extent that the points where the side thrust bearings 200 abut against the plate can be connected into a straight line, thereby ensuring the square effect.

[0145] Furthermore, the side-pushing device 22 is provided with two layers of structures, upper and lower, for side-pushing and adjusting the plate.

[0146] Specifically, the lower structure includes a side push fine adjustment component 2204, abutment plate 2205, and a side push lower guide rail 2206. When the control system of the edge banding machine 3 adjusts the feed reference line according to production requirements, resulting in a change in the pre-milling amount of the plate, the side push fine adjustment component 2204 can be adjusted accordingly according to the change to ensure that the side push edge of the side push device 22 can be on the same straight line as the feed reference line of the edge banding machine 3. The lower structure realizes side push fine adjustment in an electric manner, without the need for manual adjustment by the user, effectively realizing automatic docking and improving production efficiency.

The pressure wheel 2352 is at an acute angle with the plate, causing the plate to move closer to the inner side of the side-pushing, and can fit tightly in a straight line with the side-pushing edge. The pressure wheel 2352 is installed on both sides of the pressure wheel mounting plate 2341 in an alternating manner.

The roller table 41 is located at the discharge end of the edge banding machine 3, and the return straight-row roller line 43 is located at one side of the roller table 41. One end of the return straight-row roller line 43 abuts against the feed oblique roller line 12, and the discharge end of the return straight-row roller line 43 is connected to the unloading mechanism 5.

The first lifting device and the second lifting device lift the plate based on the position information of the sensing device.

After the edge-banded plate enters the roller table 41, the position of the plate on the roller table 41 is detected by the sensing device, and the first lifting device and the second lifting device are used to lift the two plates respectively, so as to realize the collection and separation of the plates.

After the plate enters the pre-milling position of the edge banding machine 3, the floating milling mechanism 6 can simultaneously process the unsealed edge of the plate according to the actual situation; the plate enters the intelligent edge banding machine 3 for edge banding, and the plate is visually inspected by the visual inspection mechanism 7 after the edge banding is completed. The edge banding quality is not limited to 2D or 3D visual inspection, and the effect is finally evaluated; after the material is discharged, the workpiece is collected and processed by the rotary mechanism 4, which can realize a single transport 1 After individual or multiple plates are collected, they are transported and transferred to the reflux inline roller line 43 for reflux treatment; if all edges are not completely sealed, secondary transport and circulation reflux are carried out through the first gantry transport mechanism 42 and the second gantry transport mechanism 43; they are transported to the top of the feeding oblique roller line 12 for reflux and material separation process. If multiple workpieces are transported at the same time, the workpiece separation must be carried out here, and the above steps are repeated for each workpiece in steps; if all edges are completely sealed, there is no need for gantry transport and reflux after passing through the reflux inline roller line 43, and it is only necessary to bridge the unloading mechanism 5 (such as an unloading air flotation table) at the end of the reflux inline roller line 43 for manual unloading.
