Noodle bowl angle detection method of drum instant noodles on production line

Abstract

The present invention relates to a noodle bowl angle detection method of drum instant noodles on a production line. The method comprises the steps of: selecting a noodle bowl located at a standard position directly facing a lid, allowing a camera lens to directly face a noodle bowl QS sign, and employing a calibration clamping tool to ensure that the QS sign appears at the center of a green crossof a display photo frame of a display; taking the position of the QS sign as a 0-degree coordinate point, establishing a QS template, and selecting the QS sign in the image as a template; allowing a motor to make a leap to the left about 25 degrees, allowing the motor to make a leap to the right at regular intervals starting from the position and make a leap about 0.5 degrees each interval until the total leap reaches 50 degrees, wherein the change amount of the horizontal axis coordinate of the QS sign corresponds to the angle of the leap for each time; performing linear optimization in the leap intervals, and obtaining the angle corresponding to each deviation of one pixel point; for lid seal of drum instant noodles to be aligned, searching the position of the noodle bowl QS; and obtaining a regulation angle of the noodle bowl.

Description

technical field [0001] The invention relates to a method for detecting the angle of barreled noodle bowls on a production line. Background technique [0002] On the barreled noodle production line, the tray carries the noodle bowls and runs forward, successively passes through the noodles, the feeding bag, the fork, and then enters the capping stage. Since there is a QS mark on the packaging of each barreled noodle, there is a QS mark on the lid. A sign that is easy to tear, usually the noodle bowls of barreled noodles are randomly placed, resulting in inconsistent patterns between the noodle bowls and the noodle bowls, and products with chaotic outer packaging patterns will directly affect the market image of the manufacturer after entering the market. On the production line, the orientation of the lid is fixed, and the orientation of the noodle bowl is random. In order to align and seal, the angle of the noodle bowl needs to be detected.
