The angular displacement sensor is fixed on the frame. An output shaft of the angular displacement sensor is fixed with the turnover detection rod. The detection roller 17 is supported at the outer end of the turnover detection lever 23. The axis of the detection roller 17 is in the same vertical plane as the axis of the secondary transmission shaft close to the primary conveying assembly 2. Both ends of the side surface of the detection roller 17 are in contact with two secondary conveyor belts 19, respectively. When the wrapping bag reachd and detect gyro wheel 17 department, because the wrapping bag has thickness, so can raise and detect gyro wheel 17, and then make upset measuring pole 23 take place to overturn. The single and double bags allow the reverse sensing bar 23 to be reversed at different angles. Therefore, the angular displacement sensor 27 detects the turning angle of the turning detection lever 23, and can determine whether or not the packaging bag passing through the detection roller 17 is overlapped. In addition, the angular displacement sensor 27 also functions to count the number of passing wrapping tapes.

The ultrasonic transmitter 18 is above the top surface of the two secondary belts 19 and the ultrasonic receiver is below the top surface of the two secondary belts 19. When the bag passes between the ultrasonic emitter 18 and the ultrasonic receiver, the bag will affect the transmission of the ultrasonic waves, causing the ultrasonic signal received by the ultrasonic receiver to change. The ultrasonic signal received by the ultrasonic receiver when the overlapped packaging bag passes between the ultrasonic transmitter 18 and the ultrasonic receiver is different from the ultrasonic signal received by the ultrasonic receiver when the single packaging bag passes between the ultrasonic transmitter 18 and the ultrasonic receiver. Thereby the detection of the packing bag overlapping is realized. By means of two different forms and principles of re-sheet detection, the condition of missed detection can be avoided to the utmost extent.

The inner end of the turning rod 38 is fixed with one end of the turning shaft 36, and the axis of the turning rod is perpendicular to the axis of the turning shaft 36. The outer end of the turning rod 38 is provided with a driving chute. The driving column extends into the driving chute. The turning rod can be turned by the rotation of the rejecting motor 24, so that the turning shaft 36 is rotated. The slide 22 is fixed to the rear end of the frame and has a top surface inclined toward the side away from the secondary conveyor assembly 5. The top edge of slide 22 is flush with the bottom edge of flap 21. In a state where the top edge of flap 21 is turned to the highest position, the top edge of flap 21 is higher than the top surface of secondary belt 19. A waste collection box is arranged right below the turning plate 21. A finished product collection box is arranged just below the bottom edge of the slide plate 22.
In the initial state, the packaging bag can directly enter the finished product collecting box through the turning plate 21 and the sliding plate 22 after being output from the secondary transmission belt 19. When the turning plate 21 is turned up, the packaging bag is stopped by the turning plate 21 after being output from the secondary transmission belt 19 and falls into the waste collection box.
The working principle of the utility model is as follows:
An operator places a stack of packaging bags between the two lateral limiting baffle plates and rotates the packaging bag adjusting hand wheel 34, so that the two lateral limiting baffle plates are in contact with the packaging bags (namely the distance between the two lateral limiting baffle plates is equal to the width of the packaging bags).
The feeding transmission assembly 32, the accelerating transmission assembly 30, the primary conveying assembly 2 and the secondary conveying assembly 5 are started, and the paging mechanism separates the stacked packaging bags one by one into the primary conveying belt 13. The first-level conveying assembly 2 conveys the packaging bags conveyed by the paging mechanism to the position right below the code spraying detection mechanism 3 for code spraying and photographing, and judges whether code spraying errors exist in the packaging bags according to the obtained pictures (judging whether code spraying errors are the prior art according to images). And taking the packaging bag with the wrong code as the wrong packaging bag. The packaging bags which are subjected to code spraying and shooting enter the secondary conveying assembly 5. The double-sheet detection mechanism 4 detects double-sheet of the packaging bag entering the secondary conveying assembly 5. And the packaging bag with the problem of overlapping is used as an overlapping packaging bag.
When the wrong packaging bag or the overlapped packaging bag reaches the end, close to the automatic rejecting mechanism 6, of the secondary conveying assembly 5, the rejecting driving assembly drives the turning shaft 36 to rotate, so that the turning plate 21 is turned up, and the wrong packaging bag or the overlapped packaging bag is blocked by the turning plate 21 and falls into the waste collecting box. Thereafter, the reject driving assembly drives the tumble shaft 36 to reset. When other packaging bags reach the end of the secondary conveying assembly 5 close to the automatic rejecting mechanism 6, the rejecting driving assembly does not move, and the packaging bags enter the finished product collecting box through the guide of the turning plate 21 and the sliding plate 22.
The code spraying detection mechanism 3 specifically comprises the following principles of code spraying and photographing for the packaging bag:
The incoming material sensor 14 detects one package at a time, the automatic code spraying machine 15 sprays information to be printed on the package at a time, and the optical camera 26 takes a picture. The time when the automatic code spraying machine 15 sprays the codes is a time later than the time when the incoming material sensor 14 detects the corresponding packaging bag. The moment of shooting by the optical camera 26 is b times later than the moment of detection of the corresponding package by the incoming material sensor 14.
a is the required time for the packaging bag to reach the position right below the automatic code spraying machine 15 from the position right below the feeding sensor 14 (namely, the distance between the detection head of the feeding sensor 14 and the code spraying port of the automatic code spraying machine 15 along the conveying direction of the secondary conveyor belt is divided by the conveying speed of the secondary conveyor belt). b is the time required for the package bag to reach from just below the feed sensor 14 to just below the optical camera 26 (i.e., the distance between the detection head of the feed sensor 14 and the lens of the optical camera 26 in the secondary conveyor transport direction divided by the secondary conveyor transport speed).
the principle of the double-sheet detection mechanism 4 for detecting the double-sheet of the packaging bag is as follows:
when one packaging bag passes through the detection roller 17, if the angular displacement sensor 27 detects that the turning angle of the turning detection rod 23 is larger than theta, the corresponding packaging bag is used as a double-piece packaging bag. θ 1.2 arcsin (δ l); where δ is the thickness of a single package and l is the length of the upset test bar 23.
When one packaging bag passes between the ultrasonic transmitter 18 and the ultrasonic receiver, the ultrasonic receiver receives an ultrasonic signal corresponding to the re-opened packaging bag, and the corresponding packaging bag is used as the re-opened packaging bag.
