[0029] This invention provides an automated palletizing workstation for foam boards, such as... Figure 1 As shown, it includes a slitting machine 1, a conveyor frame 2, a material pulling device 5, a material support platform 3, and a robotic arm 4.

[0030] like Figure 2 , Figure 3 As shown, the conveyor frame 2 includes a frame 2.1, on which a roller frame 2.3 is provided. The roller frame 2.3 is provided with an upper roller 2.4 and a lower roller 2.5. The roller frame 2.3 is also provided with a drive device for driving the lower roller 2.5 to rotate. A downward inclined transition frame 2.2 is provided on the side of the frame 2.1 near the conveyor frame 2, with the front end of the transition frame 2.2 facing the discharge port of the slitting machine 1.

[0031] There are two upper rollers 2.4 and two lower rollers 2.5. Each roller has a seated bearing 2.6 rotatably connected to both ends. The roller frame 2.3 is equipped with multiple limiting strips 2.8. Each seated bearing 2.6 has grooves on both sides, which slide in engagement with the limiting strips 2.8 on the roller frame 2.3. The roller frame 2.3 is also equipped with a lifting cylinder 2.7 that drives the upper roller 2.4 to slide up and down along the roller frame 2.3. The piston rod end of the lifting cylinder 2.7 is connected to the seated bearing 2.6 of the upper roller 2.4. Multiple U-shaped washers 2.9 are provided between the bottom of the seated bearing 2.6 of the lower roller 2.5 and the roller frame 2.3.

[0032] like Figure 4 As shown, the material support platform 3 includes multiple spaced square tubes 3.1, and each square tube 3.1 has a downward inclined plate 3.2 on the side near the conveyor frame.

[0033] like Figure 5 As shown, the robotic arm 4 includes a crossbeam 4.1, a column 4.2 slidably connected to the crossbeam 4.1, a connecting frame 4.3 slidably connected to the column 4.2, a flipping frame 4.4 rotatably connected to the front end of the connecting frame 4.3, and multiple suction cup assemblies 4.5 provided on the flipping frame 4.3; the connecting frame 4.3 is also provided with a drive device for driving the flipping frame 4.4 to rotate 180 degrees, and the robotic arm 4 is also provided with a drive device for driving the column 4.2 to move along the crossbeam 4.1 and a drive device for driving the connecting frame 4.3 to move along the column 4.2.

[0034] like Figure 6 , Figure 7 , Figure 8 As shown, the material pulling device 5 includes a bracket 5.1, on which a material pulling mechanism 5.3 is slidably connected. The bracket 5.1 of the material pulling device 5 is provided with a rack 5.2 along its length. The bottom of the material pulling mechanism 5.3 is provided with a gear 5.4.2 that meshes with the rack 5.2. The drive motor 5.9 drives the gear 5.4.2 to rotate, causing the material pulling mechanism 5.3 to slide along the bracket 5.1.

[0035] The material pulling mechanism 5.3 includes a slide table 5.4. A crossbar 5.10 is provided on one side of the slide table 5.4. A material pulling plate 5.5 is connected to the front end of the crossbar 5.10. The material pulling plate 5.5 is inclined upward on the side closer to the slitting machine 1. A clamping cylinder 5.7 is provided on the other side of the material pulling plate 5.5. The clamping cylinder 5.7 is a lever cylinder. A T-shaped pressure arm 5.6 is connected to the lever arm of the clamping cylinder 5.7. A bolt 5.8 for clamping the workpiece is screwed onto the T-shaped pressure arm 5.6.

[0036] The bottom of the material pulling mechanism 5.3 is provided with multiple first limiting pulleys 5.4.1 and second limiting pulleys 5.4.3. The first limiting pulleys 5.4.1 are used to limit the material pulling mechanism 5.3 in the left and right directions, and the second limiting pulleys 5.4.3 are used to limit the material pulling mechanism 5.3 in the up and down directions. The material pulling mechanism 5.3 is slidably connected to the bracket 5.1 through the first limiting pulleys 5.4.1 and the second limiting pulleys 5.4.3.

[0037] When the slitting machine 1 discharges material, the sheet material from the upper discharge port passes through the transition frame 2.2 of the conveyor frame 2 to the roller frame 2.3, and is then conveyed to the material support platform 3, where it is picked up by the robotic arm 4. The sheet material from the lower discharge port is picked up by the front end by the pulling device 5, and then the pulling mechanism 5.3 moves with the conveying speed of the slitting machine 1 until the sheet material is released after it comes out of the slitting machine 1, and the sheet material falls onto the trolley for stacking.

[0038] The lifting cylinder 2.7 on the conveyor frame 2 controls the lifting and lowering of the upper roller 2.4, which can change the tilt angle and forward direction of the sheet material, allowing the sheet material to enter the material support platform 3 smoothly. The lower roller 2.5 provides conveying power for the sheet material. The height of the lower roller 2.5 can be adjusted by the U-shaped shim 2.9 to accommodate sheets of different thicknesses. When the sheet material is about to come out of the slitting machine 1, the slitting machine 1 no longer provides conveying power. At this time, the lifting cylinder 2.7 descends, and the upper roller 2.4 and lower roller 2.5 clamp the sheet material, pulling it out of the slitting machine 1.

[0039] The gap between the square tubes 3.1 of the material support platform 3 allows the suction cup assembly 4.5 of the robot arm 4 to pass through. The inclined plate 3.2 on one side of the square tube 3.1 guides the material and prevents the front end of the material from sagging.

[0040] Since it is difficult to hold the material by using the robot arm 4 to grab it from above, this embodiment adopts the method of dragging the material from below. First, the suction cup assembly 4.5 is flipped upward to lift the workpiece. After the robot arm 4 is moved to the stacking position, the flipping frame 4.4 is flipped 180 degrees downward, and the material loses suction and falls to the stack.

[0041] The clamping cylinder 5.7 and the pulling plate 5.5 of the pulling mechanism 5.3 are used to grip the sheet metal, and the bolts 5.8 on the T-shaped pressure arm 5.6 can be adjusted to accommodate sheet metal of different thicknesses.

[0042] This equipment can be used for both the slicing and peeling processes. During peeling, the material pulling device 5 stops operating, and the material pulling mechanism 5.3 retracts to the side away from the slicing machine 1. The processed sheet is then conveyed by the conveyor frame 2 to the stacking platform 3, where the outer skin is manually collected from the space at the bottom of the conveyor frame 2. During slicing, the material pulling mechanism 5.3 of the material pulling device 5 moves under the conveyor frame 2. The two sets of equipment do not interfere with each other, resulting in high space utilization.

[0043] In this embodiment, multiple sensors for detecting materials are also provided, and the driving devices used are all motors. All electrical structures involved are connected to a PLC controller to achieve automated control, which is a conventional technical means in this field.

[0044] It will be apparent to those skilled in the art that the present invention can be modified in various ways, and such modifications are not considered to depart from the scope of the invention. All such modifications that are obvious to those skilled in the art are included within the scope of the claims of the present invention.
