Preferably, the detection of the printed film of the packaging bag is performed in a printing section or a quality inspection section.
As a preferable technical scheme, a visual detection system is arranged to detect the printed film of the packaging bag.
As a preferable technical scheme, the visual detection system comprises an image acquisition device for photographing the printed film of the packaging bag and software for analyzing and judging the image.
As a preferable technical scheme, the defective packaging bag comprises one or more of a packaging bag with printing defects, a contaminated packaging bag, a packaging bag with foreign matters and a packaging bag with seams.
As a preferred technical scheme, the position information of the defective packaging bags is transmitted to the rejecting device in an online digital transmission or offline storage medium transmission mode.
According to the preferable technical scheme, the removing device comprises a transmission mechanism, a removing channel and a removing mechanism, the removing channel comprises a gap in the transmission mechanism, the removing mechanism is located above the removing channel, and the removing mechanism removes the packaging bags downwards from the removing channel after receiving a removing signal.
According to the preferable technical scheme, the removing mechanism comprises a pressing module and/or a guiding module, when the removing mechanism receives a removing signal, the removing mechanism extends downwards, the guiding module guides the packaging bag to the removing channel, and the pressing module presses the packaging bag downwards towards the removing channel.
As the preferred technical scheme, the rejecting mechanism receives a rejecting signal before the imperfect packaging bag reaches the rejecting channel or when the imperfect packaging bag reaches the rejecting channel.
The invention has the beneficial effects that:
the invention adopts a method of firstly detecting the defective packaging bag off line, recording the position information of the defective packaging bag, and then removing the defective packaging bag according to the recorded position information when processing the packaging bag on line. Because the bag making machine is separated during off-line detection, the interference of large vibration of the bag making machine on image acquisition and detection and identification is avoided, defective packaging bags can be accurately detected and identified, and accurate defective product elimination is realized.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described with reference to the accompanying drawings.
The connection means that the two mechanisms are in contact or close to each other, so that the packaging bag of the upstream mechanism can be smoothly conveyed to the downstream mechanism.
According to the invention, the removing mechanism can only comprise the pressing module, only comprise the guiding module, and simultaneously comprise the pressing module and the guiding module.
An automatic defective packaging bag removing method comprises the following steps:
detecting the printed film of the packaging bag, recording the position information of the defective packaging bag, and then rolling the packaging bag, as shown in figure 1;
placing the rolled packaging bag printing film on a bag making machine 1, and unreeling to process the packaging bag as shown in fig. 2;
the bag outlet end of the bag making machine 1 is connected with the rejecting device 2, the rejecting device receives the position information of the defective packaging bag and calculates according to the position information, and when the defective packaging bag reaches the rejecting position of the rejecting device 2, the rejecting device 2 rejects the defective packaging bag, as shown in fig. 2.
The detection of the printed film of the packaging bag can be carried out in a printing section or a quality inspection section, and the detection is an off-line detection method.
As shown in fig. 1, during the inspection at the quality inspection section, one end of the packaging bag printed film is unwound in a roll form, the other end of the packaging bag printed film is wound in a roll form, and the visual inspection system is arranged to inspect the packaging bag printed film, and comprises an image acquisition device for photographing the packaging bag printed film and software for analyzing and judging the image. The image acquisition device acquires the pattern of the packaging bag, the software compares the acquired pattern with a preset pattern, if the acquired pattern is inconsistent with the preset pattern, such as printing defects, pollution, foreign matters, seams (caused by cutting, splicing and the like of a packaging bag printing film) and the like, the packaging bag is judged to be defective, and the processor records the position information of the defective packaging bag. And then, the position information of the defective packaging bag is transmitted to a rejecting device in an online digital transmission or offline storage medium transmission mode.
As shown in fig. 3 and 4, the rejecting device 2 includes a transmission mechanism 3, a rejecting channel 4 and a rejecting mechanism 5, the rejecting channel 4 includes a gap on the transmission mechanism 3, the rejecting mechanism 5 is located above the rejecting channel 4, and the rejecting mechanism 5 rejects the packaging bag downwards from the rejecting channel 4 after receiving a rejecting signal.
As a structural form of the rejecting mechanism 5, the rejecting mechanism 5 includes a pressing module and/or a guiding module, when the rejecting mechanism 5 receives a rejecting signal, the rejecting mechanism 5 extends downwards, the guiding module guides the packaging bag to the rejecting channel 4, and the pressing module presses the packaging bag downwards towards the rejecting channel 4. The removing mechanism 5 may only comprise a pressing module, a guiding module, and a pressing module and a guiding module, and the guiding module and the pressing module are integrally arranged in the drawing.
The guiding module needs to execute the rejecting action before the defective packaging bag reaches the rejecting channel 4, and the pressing module needs to execute the rejecting action when the defective packaging bag reaches the rejecting channel 4. When the pressing module and the guiding module are simultaneously included, the time precision requirement of executing the removing action can be properly relaxed, and the removing mechanism 5 receives a removing signal to execute the removing action when the defective packaging bag reaches the removing channel 4 or reaches the removing channel 4, so that the removing can be finished.
