Method for removing piece goods from a conveyor, blowoff device and sorting system

A method for removing a piece good from a conveying means of a sorting system, wherein the sorting system comprises the conveying means for conveying the piece good in a transport direction along a conveyor line configured as a circular line, and wherein the conveying means is configured in such a way that a piece good arranged in a cell area on the conveying means is movable at right angles to the transport direction, comprising the steps:

• generating image data by means of a camera arranged on the conveyor line, wherein the image data represent at least the conveying means in one section of the conveyor line at a camera detection area,
• by means of a controller, detecting a piece good not placed completely in the cell area on the conveying means on the basis of the image data generated,
• by means of the controller, classifying the piece good not placed completely in the cell area on the conveying means with regard to a property of the piece good on the basis of the image data generated,
• generating a blowoff command for a blowoff device arranged on the conveyor line at a blowoff location,
• by means of the blowoff device, blowing off the piece good not placed completely in the cell area on the conveying means on the basis of the blowoff command,
• checking if the blowoff is successful by means of a light barrier after the blowoff, and receiving a check signal generated by the light barrier,
• wherein the blowoff command is generated by means of machine learning while considering a time of the generation of the image data which is when the camera detects the piece good on the conveyor line at the camera detection area, a conveying speed of the conveyor line, an arrangement of the camera, the conveyor line and the blowoff device relative to one another and while considering the check signal generated from previous blowoffs and the classification of the piece good,
• wherein a time delay is between the time of the generation of the image data and the time the piece good is located at the blowoff location and is determined by the conveying speed of the conveyor line and a distance between the camera detection area and the blowoff location, and wherein the blowoff command is generated so that the blowoff device blows when the piece good is located at the blowoff location.
