[0021] like Figure 1 As shown, this automated material handling and packaging production line includes a frame 1 and a first conveying mechanism 2. A forward and reverse rotation correction mechanism 3 is located in front of the first conveying mechanism 2. Figure 2 and Figure 3 As shown, the forward and reverse rotation correction mechanism 3 includes a rotating cylinder 31, a rotating base 30, and a forward and reverse rotation power source 32. The rotating cylinder 31 is rotatably mounted on the rotating base 30, and the rotating cylinder 31 is installed at an angle around its axis (the axis of the rotating cylinder 31 is installed at an angle). The rotating cylinder 31 is connected to the forward and reverse rotation power source 32 that drives the rotating cylinder 31 to rotate along its axis. The rotating cylinder 31 has a hollow channel 310 along its axis, which has an inlet 311 and an outlet 312. The inlet 311 of the hollow channel 310 is higher than the outlet 312 of the hollow channel 310. The inlet 311 of the hollow channel 310 faces one end of the first conveying mechanism 2. A first vision detector 7 is provided above the first conveying mechanism 2, and the first vision detector 7 controls the operation of the forward and reverse rotation power source 32 through a control center.

[0022] The working process of forward and reverse rotation correction is as follows: The first conveying mechanism 2 conveys the packaging bag to the feed port 311 of the rotating drum 31; the first vision detector 7 captures the pattern on the surface of the packaging bag (which can be detected by other detection methods) and determines its front and back orientation; if the detection shows the back facing up, the control center starts the forward and reverse rotation power source 32, drives the rotating drum 31 to rotate 180°, so that the packaging bag flips in the hollow channel 310 and slides into the second conveying mechanism 4; if the detection shows the front facing up, the rotating drum 31 remains stationary, and the packaging bag slides directly out of the discharge port 312 of the hollow channel 310.

[0023] like Figure 5 As shown, the inner wall of the hollow channel 310 has a first end face 3100 and a second end face 3101 facing each other. The two end faces are used to restrict the posture of the packaging bag within the hollow channel 310. When the packaging bag enters the hollow channel 310, it is located on the first end face 3100 of the hollow channel 310. When the packaging bag rotates 180° out, it is located on the second end face 3101 of the hollow channel 310.

[0024] After the packaging bags enter the second conveyor mechanism 4, even though the front of the packaging bags is facing up, it is still required that the orientation of the patterns on the packaging bags be consistent.

[0025] Therefore, such as Figure 1 As shown, the discharge port 312 of the hollow channel 310 faces one end of the second conveying mechanism 4. A horizontal rotation correction mechanism 5 is provided above the second conveying mechanism 4. The horizontal rotation correction mechanism 5 is connected to a horizontal moving mechanism 6 that drives the horizontal rotation correction mechanism 5 to move along the feeding direction of the second conveying mechanism 4. The horizontal moving mechanism 6 can drive the horizontal rotation correction mechanism 5 to move along the feeding direction of the second conveying mechanism 4, moving together with the second conveying mechanism 4. Figure 6 As shown, the horizontal rotation correction mechanism 5 includes a suction rod 50, a suction rod seat 51, a connecting support 52, a horizontal rotation power source 54, and a lifting power source 55. The suction rod 50 is rotatably mounted on the suction rod seat 51 via bearings. The suction rod seat 51 is vertically mounted on the connecting support 52. Both the horizontal rotation power source 54 and the lifting power source 55 are mounted on the connecting support 52. The connecting support 52 is connected to the horizontal moving mechanism 6. The lifting power source 55 is drively connected to the suction rod seat 51. The horizontal rotation power source 54 is connected to the rotating seat 53. The transmission connection includes a splined hole on the rotating seat 53 and a splined shaft 501 on the suction rod 50. The splined shaft 501 passes through the splined hole of the rotating seat 53 (this allows the suction rod 50 to move up and down and rotate). A second vision detector 8 is provided above the second conveying mechanism 4. The second vision detector 8 is located between the forward and reverse rotation correction mechanism 3 and the horizontal rotation correction mechanism 5. The second vision detector 8 controls the horizontal moving mechanism 6, the horizontal rotation power source 54 and the lifting power source 55 through the control center.

[0026] The working principle of horizontal rotation correction is as follows: The second vision detector identifies whether the pattern on the front of the packaging bag is facing the conveying direction (this can be detected by other detection methods); if the detection indicates that the pattern is not facing the conveying direction, the control center controls the lifting power source 55 to drive the suction rod seat 51 to move the suction rod 50 downward. After the suction rod 50 moves downward, it sucks up the packaging bag. Then, the lifting power source 55 drives the suction rod seat 51 to move the suction rod 50 upward. During the upward movement, the horizontal rotation power source 54 drives the suction rod 50 to rotate horizontally through the rotating seat 53, rotating 180°. During the up and down movement of the packaging bag, the horizontal moving mechanism 6 drives the horizontal rotation correction mechanism 5 to move along the feeding direction of the second conveying mechanism 4, that is, to make the packaging bag follow the second conveying mechanism 4 and move forward together, so that the corrected packaging bag is released back to the original position of the second conveying mechanism 4.

[0027] The horizontal moving mechanism 6 is a linear module, but it can also be driven by a regular synchronous belt or chain.

[0028] In order for the lifting power source 55 to drive the suction rod base 51 to move up and down, such as Figure 6 As shown, the lifting power source 55 is connected to the transmission wheel 56. The transmission wheel 56 is equipped with an eccentric column, which is hinged to one end of the pull rod 57. The other end of the pull rod 57 is hinged to the suction rod seat 51. When the lifting power source 55 drives the transmission wheel 56 to rotate, the eccentric column on the transmission wheel 56 drives the pull rod 57 to move up and down. The pull rod 57 then pulls the suction rod seat 51 up and down, which in turn moves the suction rod 50 up and down.

[0029] like Figure 3 As shown, the rotating cylinder 31 is rotatably mounted on the rotating base 30 via bearings. A driven synchronous pulley 33 is connected to the rotating cylinder 31, and a driving synchronous pulley 34 is connected to the output shaft of the forward and reverse rotation power source 32. A synchronous belt 35 is wound around the driving synchronous pulley 34 and the driven synchronous pulley 33. Driven by the forward and reverse rotation power source 32, the driving synchronous pulley 34 drives the driven synchronous pulley 33 to rotate via the synchronous belt 35. Since the driven synchronous pulley 33 is connected to the rotating cylinder 31, the rotating cylinder 31 rotates.

[0030] like Figure 4 As shown, the inlet 311 of the hollow channel 310 is funnel-shaped, which increases the inlet cross-sectional area and prevents the packaging bag from getting stuck.

[0031] Both the first visual detector 7 and the second visual detector 8 are cameras. Both cameras are high-frame-rate industrial cameras, equipped with LED ring light sources, to meet the image acquisition needs of high-speed production lines.

[0032] Finally, it is worth mentioning that the first conveying mechanism 2 includes a first conveyor belt or ramp, and the second conveying mechanism 4 includes a second conveyor belt. Both the first and second conveyor belts are used to transport packaging bags.
