Description

Technical Field

[0001] This invention relates to the field of workpiece differentiation and unloading technology in production lines, and particularly to a plate sorting and automatic unloading system. Background Technology

[0002] Edge banding of boards refers to the processing of the edges or surfaces of materials such as wood boards and engineered wood panels by applying a layer of edge banding material to achieve the effects of moisture prevention, reducing formaldehyde release, aesthetics, and durability.

[0003] There are two types of edge banding for boards: four-sided edge banding and six-sided edge banding. When processing boards on an automated edge banding production line, the boards undergo uniform edge banding processing on the edge banding machine. The board types at the exit of the edge banding machine are B-boards (six-sided edge banding boards) and Z-boards (four-sided edge banding boards). The proportion of each type of board is different, and they are transported together by the conveying mechanism. Before the next process (such as board drilling), different types of boards need to be grouped when feeding, such as several identical B-boards forming a group (forming a complete layer) or several identical Z-boards forming a group (forming a complete layer). Then, they enter the six-sided drilling process that can process a group of B-boards, or the four-sided drilling process that can process a group of Z-boards.

[0004] When exporting edge banding machines, they cannot group mixed types of edge banding boards for cutting. This requires manual cutting of different types of boards, which is labor-intensive, cannot keep up with the production line's pace, and has low efficiency. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a board diversion and automatic unloading system that can group different types of boards from the edge banding machine outlet into specified quantities and transport them to the unloading position of the next process, and has the characteristics of high efficiency.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows:

[0007] A panel diversion and automatic unloading system, characterized in that it includes an edge banding panel outlet, a conveyor line connected to the edge banding panel outlet for conveying panels, a handling robot set on one side of the conveyor line that can identify and handle panels, a buffer rack set around the handling robot for storing panels, and an unloading position set around the handling robot for transporting panels to the next processing step.

[0008] The board includes Z-shaped boards and B-shaped boards that are continuously conveyed on the conveyor line towards the edge banding board outlet. The conveyor line is equipped with a working area for a handling robot to identify the board and perform handling operations. The handling robot is equipped with an identification device that can identify and distinguish between Z-shaped boards and B-shaped boards.

[0009] At least N pieces of sheet metal appear simultaneously in the working area, where N ≥ 2; when X consecutive Z-shaped sheets appear in the working area, the handling robot can simultaneously transport these X consecutive Z-shaped sheets to the unloading position, where 2 ≤ X ≤ N; when Y consecutive B-shaped sheets appear in the working area, the handling robot can simultaneously transport these Y consecutive B-shaped sheets to the unloading position, where 2 ≤ Y ≤ N; where X = Y.

[0010] The unloading positions include a first unloading position for placing B-type plates and a second unloading position for placing Z-type plates.

[0011] As one embodiment, the step of the handling robot identifying and handling the sheet metal from the work area to the unloading position includes:

[0012] S1: The handling robot simultaneously transports X consecutive Z-shaped plates within the work area and places them at the second unloading position, or simultaneously transports Y consecutive B-shaped plates and places them at the first unloading position;

[0013] S10: When there are no consecutive X pieces of Z-type plates or consecutive Y pieces of B-type plates in the working area, step S1 is skipped and step S2 is performed.

[0014] S2: When there are X1 Z-type boards and Y1 B-type boards in the work area, and X1≥Y1, the handling robot will move the B-type boards to the buffer rack; when there are X1 Z-type boards and Y1 B-type boards in the work area, and X1≤Y1, the handling robot will move the Z-type boards to the buffer rack.

[0015] S3: Return to step S1.

[0016] In another embodiment, the steps of the handling robot identifying and handling the sheet metal from the work area to the unloading position include:

[0017] SS1: The handling robot simultaneously transports X consecutive Z-shaped plates within the work area and places them at the second unloading position, or simultaneously transports Y consecutive B-shaped plates and places them at the first unloading position;

[0018] SS10: If no consecutive X pieces of Z-type plates or consecutive Y pieces of B-type plates appear in the working area, skip step SS1 and proceed to step SS2.

[0019] SS2: When the rearmost part of the working area is a Z-shaped plate, and there are X2 consecutive Z-shaped plates from back to front, and X2 < X, the handling robot moves X-X2 Z-shaped plates from the buffer frame to the rearmost part of the working area; when the rearmost part of the working area is a B-shaped plate, and there are Y2 consecutive B-shaped plates from back to front, and Y2 < Y, the handling robot moves Y-Y2 B-shaped plates from the buffer frame to the rearmost part of the working area.

[0020] SS3: Return to step SS1.

[0021] The handling robot is equipped with a working radius, and the working area, buffer rack, and unloading position on the conveyor line are all located within the working radius.

[0022] There are two conveyor lines, and a transfer device is provided between the conveyor lines and the edge banding board outlet to evenly distribute the board on the two conveyor lines.

[0023] The last end of the conveyor line is connected to a manual processing area.

[0024] The transport robot is equipped with a control unit that can count the number of Z-shaped and B-shaped plates in the working area and perform calculations and judgments.

[0025] The handling robot is equipped with a clamping device that can adsorb the sheet material.

[0026] The beneficial effects of this invention are:

[0027] 1. Mixed Z-type and B-type boards are transported from the edge banding board outlet onto the conveyor line. When X consecutive Z-type boards or Y consecutive B-type boards appear on the conveyor line and are within the working radius of the handling robot, the robot first moves these X consecutive Z-type boards or Y consecutive B-type boards to a specific unloading port to complete the unloading of different types of boards. The values ​​of X and Y can be set according to actual unloading requirements. Following this operating logic, the handling robot can quickly group the Z-type and B-type boards on the conveyor line, promptly meeting the unloading requirements of the next process, resulting in a high degree of automation and high efficiency.

[0028] 2. When there are no consecutive X pieces of Z-type boards or consecutive Y pieces of B-type boards in the working area of ​​the conveyor line, i.e., when the mixing degree of Z-type boards and B-type boards is high, if the number of Z-type boards in the working area is greater than that of B-type boards, the handling robot will prioritize moving the B-type boards in the working area to the buffer rack, leaving only the Z-type boards, waiting for the subsequent boards to enter the working area, until the condition of X consecutive Z-type boards is met, at which point the handling robot will move these X consecutive Z-type boards to the second unloading position; conversely, if the number of B-type boards in the working area is greater than that of Z-type boards, the handling robot will prioritize moving the Z-type boards in the working area to the buffer rack, leaving only the B-type boards, waiting for the subsequent boards to enter the working area, until the condition of Y consecutive B-type boards is met, at which point the handling robot will move these Y consecutive B-type boards to the first unloading position. This operating logic is highly efficient in handling situations where there is a high degree of mixing between Z-type and B-type boards and a peak inflow of boards from the edge banding board outlet. On the one hand, it can store some boards on the buffer rack first to reduce the pressure on the conveyor line. On the other hand, it can also ensure the grouping and unloading of boards, resulting in a high degree of automation and high efficiency.

[0029] 3. When the feed port of the edge banding board is not saturated, there are few boards on the conveyor line, the pressure is low, and there are no consecutive X pieces of Z-type boards or consecutive Y pieces of B-type boards in the working area, the handling robot takes out the Z-type board or B-type board from the buffer rack and combines it with the corresponding board in the working area to form the corresponding type of combined board for unloading. When the buffer rack contains the corresponding board, this operating logic can promptly group the board to meet the unloading requirements of the next process, resulting in a high degree of automation and high efficiency.

[0030] 4. The edge banding board discharge port distributes the boards evenly to the two conveyor lines, which on the one hand relieves the transportation pressure on the conveyor lines, and on the other hand relieves the identification and handling pressure on the handling robot, thereby improving the overall operating efficiency of the production line.

[0031] 5. A manual processing area is connected to the last end of the conveyor line. When the edge banding board outlet is at its peak output and the buffer rack is full, some boards can flow into the manual processing area for manual handling. This ensures the production line's operating efficiency while improving the system's fault tolerance, making the system more stable and reliable. Attached Figure Description

[0032] Figure 1 This is a schematic diagram showing the distribution of each structure in the sheet metal distribution and automatic unloading system;

[0033] Figure 2 This is a schematic diagram of the various structures on a transmission line; Detailed Implementation

[0034] To make the technical problems solved by this invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of this invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to this invention are shown in the accompanying drawings, not all of them.

[0035] Reference Figure 1 or Figure 2 The present invention proposes a board diversion and automatic unloading system, characterized in that it includes an edge banding board outlet 1, a conveyor line 21 connected to the edge banding board outlet 1 for conveying board 7, a handling robot 3 set on one side of the conveyor line 21 that can identify and handle board 7, a buffer rack 4 set around the handling robot 3 for storing board 7, and an unloading position 5 set around the handling robot 3 for transporting board 7 to the next processing step.

[0036] The panel 7 includes a Z-shaped panel 70 and a B-shaped panel 71 that are continuously conveyed on the conveyor line 21 toward the edge banding material outlet 1. The conveyor line 21 is equipped with a working area 22 for the handling robot 3 to identify the panel 7 and perform handling operations. The handling robot 3 is equipped with an identification device 31 that can identify and distinguish between the Z-shaped panel 70 and the B-shaped panel 71.

[0037] At least N pieces of sheet metal 7 shall appear simultaneously in the working area 22, where N≥2; when X consecutive Z-shaped sheets 70 appear in the working area 22, the handling robot 3 can simultaneously transport these X consecutive Z-shaped sheets 70 to the unloading position 5, where 2≤X≤N; when Y consecutive B-shaped sheets 71 appear in the working area 22, the handling robot 3 can simultaneously transport these Y consecutive B-shaped sheets 71 to the unloading position 5, where 2≤Y≤N; where X=Y.

[0038] The unloading position 5 includes a first unloading position 51 for placing the B-type plate 71 and a second unloading position 50 for placing the Z-type plate 70.

[0039] Furthermore, mixed-type Z-shaped boards 70 and B-shaped boards 71 ​​are transported from the edge banding board outlet 1 onto the conveyor line 21. When X consecutive Z-shaped boards 70 or Y consecutive B-shaped boards 71 ​​appear on the conveyor line and are located within the working area 22 of the working radius 32 of the handling robot 3, the handling robot 3 first moves these X consecutive Z-shaped boards 70 or Y consecutive B-shaped boards 71 ​​to a specific unloading port 5 to complete the unloading of different types of boards 7. The values ​​of X and Y can be set according to the actual unloading requirements. Following this operating logic, the handling robot can quickly group the Z-shaped boards and B-shaped boards on the conveyor line to meet the unloading requirements of the next process in a timely manner, resulting in a high degree of automation and high efficiency.

[0040] As in Example 1, for example, X is 3 and Y is 3, that is, 3 Z-shaped plates 70 are grouped together to meet the unloading requirements of the second unloading position 50, and 3 B-shaped plates 71 are grouped together to meet the unloading requirements of the first unloading position 51. At this time, there are at least 3 plates 7 in the working area. When 3 consecutive Z-shaped plates 70 or 3 consecutive B-shaped plates appear in the working area 22, the clamping device 30 of the handling robot 3 clamps 3 consecutive Z-shaped plates and moves them to the second unloading position 50, or clamps 3 consecutive B-shaped plates and moves them to the first unloading position 51.

[0041] As an embodiment 2, the steps of the handling robot 3 identifying and handling the plate 7 from the work area 22 to the unloading position 5 include:

[0042] S1: The handling robot 3 simultaneously handles X consecutive Z-shaped plates 70 within the working area 22 and places them at the second unloading position 50, or simultaneously handles Y consecutive B-shaped plates 71 and places them at the first unloading position 51.

[0043] S10: When no consecutive X pieces of Z-type plates 70 or consecutive Y pieces of B-type plates 71 appear in the work area 22, step S1 is not performed, and step S2 is performed instead.

[0044] S2: When there are X1 Z-shaped plates 70 and Y1 B-shaped plates 71 in the working area 22, and X1≥Y1, the handling robot 3 will move the B-shaped plate 71 to the buffer rack 4; when there are X1 Z-shaped plates 70 and Y1 B-shaped plates 71 in the working area 22, and X1≤Y1, the handling robot 3 will move the Z-shaped plate 71 to the buffer rack 4.

[0045] Furthermore, Example 2 is used to address the situation where the Z-type plate 70 and the B-type plate 71 have a high degree of mixing and the peak value of the edge banding material outlet 1 is received. When no consecutive X pieces of Z-type plates 70 or consecutive Y pieces of B-type plates 71 appear in the working area 22 of the conveyor line 21, that is, when the mixing degree of Z-type plates 70 and B-type plates 71 is high, if the number of Z-type plates 70 in the working area 22 is greater than that of B-type plates 71, the handling robot 3 prioritizes to move the B-type plates 71 in the working area 22 to the buffer rack 4, leaving only the Z-type plates 70, waiting for the subsequent plates 7 to enter the working area 22, until the condition of X consecutive Z-type plates 70 appears, then the handling robot 3 moves these X consecutive Z-type plates 70 to the second unloading position 50; conversely, if the number of B-type plates 71 in the working area is greater than that of Z-type plates 70, the handling robot 3 prioritizes to move the Z-type plates 70 in the working area 22 to the buffer rack 4, leaving only the B-type plates 71, waiting for the subsequent plates 7 to enter the working area 22, until the condition of Y consecutive B-type plates 71 appears, then the handling robot moves these Y consecutive B-type plates 71 to the first unloading position 51. This operating logic is highly efficient in dealing with a high degree of mixing between Z-type boards 70 and B-type boards 71 ​​and a peak inflow of boards from the edge banding board outlet 1. On the one hand, it can store some boards on the buffer rack 4 first, reducing the pressure on the conveyor line 21. On the other hand, it can also ensure the grouping and unloading of boards 7, resulting in a high degree of automation and high efficiency.

[0046] S3: Return to step S1.

[0047] As in Example 3, the steps of the handling robot 3 identifying and handling the plate 7 from the work area 22 to the unloading station 5 include:

[0048] SS1: The handling robot 3 simultaneously handles X consecutive Z-shaped plates 70 within the working area 22 and places them at the second unloading position 50, or simultaneously handles Y consecutive B-shaped plates 71 and places them at the first unloading position 51.

[0049] SS10: If no consecutive X pieces of Z-type plates 70 or consecutive Y pieces of B-type plates 71 appear in the work area 22, step SS1 is skipped and step SS2 is performed.

[0050] SS2: When the last end of the working area 22 is a Z-shaped plate 70, and the Z-shaped plates 70 are X2 consecutive pieces from back to front, and X2 < X, the handling robot 3 moves X-X2 pieces of Z-shaped plates 70 from the buffer frame 4 to the last end of the working area 22, so that the working area 22 has X consecutive pieces of Z-shaped plates 70 from back to front; when the last end of the working area 22 is a B-shaped plate 71, and the B-shaped plates 71 are Y2 consecutive pieces from back to front, and Y2 < Y, the handling robot 3 moves Y-Y2 pieces of B-shaped plates 71 from the buffer frame 4 to the last end of the working area 22, so that the working area 22 has Y consecutive pieces of B-shaped plates 71 from back to front;

[0051] SS3: Return to step SS1.

[0052] Furthermore, the operating logic of Embodiment 3 is designed to address situations where the incoming board at the edge banding board outlet 1 is not saturated, the number of boards on the conveyor line 21 is low, and the pressure is low. At this time, if no consecutive X pieces of Z-shaped boards 70 or consecutive Y pieces of B-shaped boards 71 ​​appear in the working area 22, the handling robot 3 retrieves the Z-shaped board 70 or B-shaped board 71 from the buffer rack 4 and combines it with the corresponding board 7 at the end of the working area 22 to form the corresponding type of combined board for unloading. When the buffer rack 4 contains the corresponding board, this operating logic can promptly group the board 7 to meet the unloading requirements of the next process, resulting in a high degree of automation and efficiency.

[0053] The handling robot 3 is set with a working radius of 32. The working area 22, buffer rack 4, and unloading position 5 on the conveyor line 21 are all located within the working radius of 32.

[0054] There are two conveyor lines 21, and a transfer device 20 is provided between the conveyor lines 21 and the edge banding board outlet 1 to evenly distribute the board 7 on the two conveyor lines 21. Furthermore, the edge banding board outlet 1 evenly distributes the board 7 to the two conveyor lines 21, which on the one hand relieves the transportation pressure of the conveyor lines 21, and on the other hand relieves the identification and handling pressure of the handling robot 3, thereby improving the overall operating efficiency of the production line.

[0055] The last end of conveyor line 21 is connected to a manual processing area 8. Furthermore, this manual processing area allows some boards 7 to flow into the manual processing area 8 for manual handling when the edge banding board outlet 1 is at its peak output and the buffer rack 4 is full. This ensures the production line's operating efficiency while improving the system's fault tolerance, making the system more stable and reliable.

[0056] The handling robot 3 is equipped with a clamping device 30 that can adsorb the plate 7.

[0057] The transport robot 3 is equipped with a control unit that can count the number of Z-shaped plates 70 and B-shaped plates 71 in the working area 22 and perform calculations and judgments.
