When the material loading line for the labeled packaging bottles of the embodiment of the invention is actually operated, the packaging bottles 101 without labels enter from the input end of the labeling machine 2, after the operation of the labeling machine, labels are adhered to the corresponding positions (theoretically) on the bottle body surfaces of the packaging bottles 101, and the packaging bottles 101 with the labels adhered enter the main conveying line 1 from the output end of the labeling machine.

It should be noted that the main conveyor line 1 in the embodiment of the present invention is a flexible conveyor line, the main conveyor line 1 is always kept in a moving state during operation, when the packaging bottles 101 on the main conveyor line 1 are blocked, the packaging bottles 101 are guided or stopped from moving, and the moving state of the main conveyor line 1 is not affected.

the packaging bottle 101 firstly needs to be scanned by the code scanning device 4 on the main conveying line 1, and since the code scanning area of the code scanning device 4 is fixed, if errors such as label skew, incorrect label pasting height, wrong label bar code and the like occur on the packaging bottle 101, the code scanning device 4 can judge that the packaging bottle 101 is a packaging bottle defective product.

Then, the packaging bottles 101 pass through the removing device 5 on the main conveying line 1, the removing device 5 acts according to the code scanning result of the code scanning device 4, basically, if the code scanning device 4 judges that the packaging bottles 101 are good products, the removing device 5 is switched to a first guiding posture, and the packaging bottles 101 moving to the positions where the removing device 5 is located are driven by the main conveying line 1 to move continuously; if sweep a yard device 4 and judge that packing bottle 101 is the packing bottle defective products, under rejecting device 5 switches the second direction gesture, can let the packing bottle 101 that moves to rejecting device 5 position shift to clearance transfer chain 60 on.

the following specifically explains the specific structure of each apparatus:

main conveyor line 1

The main conveying line 1 is a flexible conveying line and always keeps moving in the operation process, the main conveying line 1 drives the packaging bottles to move based on friction force and the like, and the conveying line is of a common mechanical structure, so that the embodiment of the invention is not additionally described. Specifically, the moving direction of the main conveying line 1 is shown as the direction indicated by the arrow in fig. 1 of the accompanying drawings.

Labelling machine 2

Specifically, the labeling machine 2 may be a labeling machine in the prior art, and as for the labeling line for labeling the packaging bottles provided in the embodiment of the present invention, the labeling machine has an input end and an output end, wherein the input end is used for allowing the non-labeled packaging bottles to enter the labeling machine for labeling, and the output end is used for (theoretically) delivering the labeled packaging bottles to the main conveying line.

Specifically, the length of the buffer line 301 is greater than the distance between the buffer input baffle 302 and the buffer output baffle 304, that is, the length of the buffer line 301 is greater than the length of the main conveyor line 1 between the buffer input baffle 302 and the buffer output baffle 304; the buffer line 301 can store a certain number of packaging bottles (more than the number of packaging bottles that can be held by the main conveying line between the buffer input baffle 302 and the buffer output baffle 304), so as to provide a certain troubleshooting time for workers and avoid equipment shutdown.

note that the buffer line 301 is also a flexible conveying line.

Specifically, the flow of the packaging bottles 101 into the buffer line 301 is controlled by the buffer input baffle 301, and the flow of the packaging bottles 101 out of the buffer line 301 is controlled by the buffer output baffle 304.

Similarly, since the buffer output shutter 303 has two moving postures, the driving element of the buffer output shutter 303 may be the buffer output cylinder 305; specifically, the connection manner in which the buffer output cylinder 305 drives the buffer output baffle 303 to swing (which can be implemented based on the lever principle) is common, and the embodiment of the present invention is not specifically described.
