Container labeling position adjustment system and method for labeling container

Abstract

The invention relates to a container labeling position adjustment system and a method for labeling a container, and particularly relates to a device and a method for accurately labeling the surface of the container. Two reflective mirrors (2) are fixed on the other side of a transmission device (6), which is opposite to a first camera (4), the first camera (4) and the two reflective mirrors (2) respectively correspond to a range of 120 degrees on the circumference of the container (1), mirror images of the container (1) in the reflective mirrors (2) are positioned in an imaging range of the first camera (4), and an image of the whole surface of the container (1) can be collected by the first camera (4), so as to determine the position of a designator. The method for labeling the container comprises the following steps: calibrating the first camera (4) and a second camera (5) first, then performing coarse positioning by utilizing an image shot by the first camera (4), and finally, performing fine positioning by utilizing the second camera (5), so that one side of the designator of the container (1) and a to-be-pasted label are accurately positioned. The method has the advantages of low cost, high detection efficiency and the like.

Description

technical field [0001] The container labeling position adjustment system and the container labeling method relate to a device and method for accurately pasting labels on the container surface. Background technique [0002] The labeling of the container on the filling line is carried out by an automatic labeling machine. The label is not attached to any position of the container. The container is equipped with a convex or other structural identifier. It is required that the label must be accurate to the identifier. Positioning, while the angles of containers on the filling line are different, it is necessary to uniformly rotate the side of the container with the marker to a predetermined direction. Before turning, it is necessary to know which direction the marker is located in the container, so that it can be rotated accurately. At present, one or more cameras are used to shoot the container from multiple angles at home and abroad, so as to obtain a picture of the container ...

Problems solved by technology

Before turning, it is necessary to know which direction the marker is located in the container, so that it can be rotated accurately. At present, one or more cameras are used to shoot the container from multiple angles at home and abroad, so as to obtain a picture of the container after it is unfolded, and take pictures The required line length is increased. If a camera is used, the container needs to be rotated at least three times at one station, which requires a lot of detection time and reduces detection efficiency. However, if the container is rotated and photographed during transmission, it is necessary At least three cameras can get a complete unfolded picture, and at least one camera is required for fine positioning, so at least four cameras are needed to complete the positioning of the marker, the number of cameras is large, pallet detection, drive components and cameras Corresponding increase in control components, resulting in increased costs
