Background
The JS powder is a waterproof material, the produced JS powder is generally packaged by adopting a packaging bag, and then the packaging bag filled with the JS powder is piled up and transported in batches. In order to improve production efficiency, a conveying line is generally adopted to convey the packaging bags containing JS powder output by a packaging machine to a stacking station, and then the packaging bags containing JS powder are stacked at the stacking station and transferred in batches.
More specifically, the packaging machine sequentially outputs the packaging bags filled with JS powder to the conveying line; the package bags on the conveying line are vertically horizontal (i.e. the package bags are horizontally arranged on the conveying line, and the length direction of the package bags is consistent with the conveying direction of the conveying line). The packing bag output to the conveying line by the general packing machine is in a straight-lying state, namely, characters on the front end face of the packing bag in a straight-lying state on the conveying line are in an upright state; so that the packaging bags conveyed to the stacking station by the conveying line are normally also lying on the ground; further, a plurality of packaging bags piled into a pile are generally all lying on one another; the stacked pile has uniform appearance, and the exposed characters visible on the periphery of the whole pile are upright.
However, in the production process, a plurality of packaging bags which are output to a conveying line by a packaging machine are reversely laid, namely characters on the front end face of the vertically laid packaging bag on the conveying line are inverted; so that a plurality of bags conveyed to the palletizing station by the conveyor line may also be recumbent; further, a plurality of bags stacked in a pile may be mixed together in the normal lying state and the reverse lying state; the stacked pile has non-uniform appearance, and exposed characters visible on the periphery of the whole pile are upright and inverted, so that the pile is messy and attractive, and the product popularization effect is affected.
Therefore, the automatic identification of whether the packaging bag on the conveying line is recumbent or not and the automatic overturning of the recumbent packaging bag on the conveying line to recumbent become the current problem to be solved.
