Technical Field

[0001] This utility model relates to the technical field of flipping machines, and in particular to a thin sheet flipping machine. Background Technology

[0002] In automated production lines, there are often processes that require flipping thin sheet-like products, such as plates, fixtures, and shells (hereinafter collectively referred to as sheets), that is, flipping the sheets 180° from side A to side B on the automated production line.

[0003] Existing technologies employ robotic arms to flip the sheets. The robotic arm picks up the sheet from the automated production line, rotates it 180° to flip it, and then places it back on the production line. Besides robotic arms, existing technologies also use complex flipping machines to flip the sheets, but these methods are generally costly. Utility Model Content

The flipping mechanism is located between the infeed pull line and the outlet pull line. The flipping mechanism includes a rotating shaft and a clamping mechanism. The clamping mechanism is disposed on the side wall of the rotating shaft. The rotating shaft is used to flip the clamping mechanism to the outlet end of the infeed pull line to clamp the sheet, and to flip the clamping mechanism to the infeed end of the outlet pull line to release the sheet.

[0027] Please refer to Figure 1 This utility model provides a sheet flipping machine, including a feeding cable 1, a discharging cable 2, and a flipping mechanism 3; Figure 1The left end of the feed line 1 is the feed end and the right end is the discharge end, and the left end of the discharge line 2 is the feed end and the right end is the discharge end. The product flows into the feed line 1 from the previous process and flows out from the discharge end of the feed line 1. There is a gap between the discharge end of the feed line 1 and the feed end of the discharge line 2. A flipping mechanism 3 is arranged in the gap. The flipping mechanism 3 receives the product (sheet 100) flowing out from the discharge end of the feed line 1, flips the sheet 100, and makes the sheet 100 reach the feed end of the discharge line 2. Then the sheet 100 is conveyed by the discharge line 2 to the next process.

[0028] Specifically, the flipping mechanism 3 includes a rotating shaft 31 and a clamping mechanism 32, with the clamping mechanism 32 fixed to the side wall of the rotating shaft 31. The frame has a bearing seat and a motor, with the rotating shaft 31 mounted on the bearing seat. The motor drives the rotating shaft 31 to rotate through a transmission mechanism such as a gear or belt. The optimal position of the rotating shaft 31 is: located at the center line of the gap between the discharge end of the feed line 1 and the feed end of the discharge line 2, and the axis of the rotating shaft 31 is perpendicular to the conveying direction of the sheet 100. The rotating shaft 31 is used to flip the clamping mechanism 32 to the discharge end of the feed line 1 to clamp the sheet 100, and then flip the clamping mechanism 32 to the feed end of the discharge line 2 to release the sheet 100.

[0029] Please refer to Figure 2 Specifically, the clamping mechanism 32 includes a pair of clamping arms 321 that move vertically to clamp the opposite sides of the sheet 100. The two clamping arms 321 are initially separated and placed at the discharge end of the feed line 1, with the higher clamping arm 321 being higher than the upper surface of the sheet 100 and the lower clamping arm 321 being lower than the lower surface of the sheet 100. When the sheet 100 enters between the two clamping arms 321 under the conveying of the feed line, the two clamping arms 321 move towards each other to clamp the sheet 100. The clamping mechanism 32 preferably adopts a vertically arranged cylinder, which is fixed on the side wall of the rotating shaft 31 and is perpendicular to the rotating shaft 31.

[0030] Please refer to Figure 1 Specifically, both the feed line 1 and the discharge line 2 include two conveyor belts 4, with a gap between the two conveyor belts 4 to accommodate a clamping mechanism 32. When the clamping mechanism 32 receives the sheet 100 at the discharge end of the feed line 1, the clamping mechanism 32 extends between the two conveyor belts 4 of the feed line 1. When the clamping mechanism 32 releases the sheet 100 at the feed end of the discharge line 2, the clamping mechanism 32 extends between the two conveyor belts 4 of the discharge line 2. The conveyor belts 4 are preferably rubber band belts.

[0031] Please refer to Figure 3Furthermore, the sheet flipping machine also includes a positioning mechanism 5, which is used to position the sheet 100 on the clamping mechanism 32 at the feed end of the discharge pull line 2. Specifically, the positioning mechanism 5 includes a first positioning mechanism 51 and a second positioning mechanism 52. The first positioning mechanism 51 is used to position the sheet 100 along the conveying direction. The first positioning mechanism 51 includes a fixed part 511 and a movable part 512. The fixed part 511 is fixedly mounted on the rotating shaft 31 and / or the clamping mechanism 32. The movable part 512 is used to push the sheet 100 onto the fixed part 511 in the opposite direction of the conveying direction. Please refer to... Figure 2 When the fixing part 511 is fixed on the rotating shaft 31, it is in the form of a protrusion; when the fixing part 511 is fixed on the clamping mechanism 32, it is in the form of an L-shaped plate. The second positioning mechanism 52 is used to position the sheet 100 along the direction perpendicular to the conveying direction (i.e. the width direction of the discharge line 2). The second positioning mechanism 52 includes a linear pushing mechanism 521, such as a cylinder, provided on the frame on both sides of the discharge line 2, for pushing the sheet 100 along the width direction of the discharge line 2.

[0032] Please refer to Figure 4 Specifically, the movable part 512 includes a gripper cylinder 5121 and an extension rod 5122. The gripper cylinder 5121 is located below the conveyor belt 4 of the discharge pull line 2. The gripper of the gripper cylinder 5121 faces upward but is lower than the conveyor belt 4. The extension rod 5122 is fixed on one of the grippers of the gripper cylinder 5121 (which rotates in the direction of the flipping mechanism 3 when it moves). When the gripper cylinder 5121 opens its two grippers, the extension rod 5122 is in a horizontal position lower than the conveyor belt 4. When the gripper cylinder 5121 retracts its two grippers, the extension rod 5122 is in a vertical position higher than the conveyor belt 4 (i.e., the top of the extension rod 5122 extends above the conveyor belt 4). The extension rod 5122 is used to push the sheet 100 onto the fixed part 511 in the opposite direction of the conveying direction.

[0033] Please refer to Figure 1 Furthermore, the sheet turning machine also includes a guiding mechanism 6, which includes guide plates 61 mounted on the frames on both sides of the discharge line 2. The two guide plates 61 form a guiding channel for the sheet 100 to pass through. A first strip-shaped hole 7 is provided on the frames on both sides of the discharge line 2 along the conveying direction, and a second strip-shaped hole 611 is provided on the guide plate 61 perpendicular to the conveying direction. The guide plate 61 is fixed to the frame with bolts, which pass through the second strip-shaped hole 611 and the first strip-shaped hole 7 to lock it onto the frame. By adjusting the position of the bolt in the first strip-shaped hole 7, the position of the guide plate 61 in the length direction of the discharge line 2 can be adjusted; by adjusting the position of the bolt in the second strip-shaped hole 611, the position of the guide plate 61 in the width direction of the discharge line 2 can be adjusted.

[0034] In summary, the sheet flipping machine proposed in this embodiment of the present invention has the advantages of simple structure and operation, low failure rate and low cost compared with the prior art. The product (sheet 100) flows into the feeding line 1 from the previous process. The feeding line 1 transports the product to the clamping mechanism 32 of the flipping mechanism 3. As the rotating shaft 31 rotates, the product is flipped and placed on the discharge line 2. The discharge line 2 transports the product to the next process.

[0035] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
