A code reading device that can prevent mislabeling of cigarette turnover boxes

Abstract

The invention discloses a code reading device capable of preventing cigarette turnover boxes from being wrongly pasted, and belongs to the technical field of code reading devices. A code-reading device that can prevent cigarette turnover boxes from being wrongly pasted, including an equipment rack, a conveyor belt is arranged inside the equipment rack, a fixing plate is welded on the top surface of the equipment rack on the right side of the equipment plate, and the front wall of the fixing plate runs through There is a pusher component, the left wall of the storage box is provided with a percussion hammer, and the left wall of the storage box is welded with a bell. By setting the transmission component, the conveyor belt will be driven to rotate when the roller is driven by the motor, thereby driving the turnover. When the turnover box moves to the position of the code-reading camera, it will be limited by the interception plate, so that the turnover box cannot continue to move and keep stopping for a period of time. At this time, the code-reading camera will check the label on the turnover box To read, provide a certain amount of time for the code-reading camera, so that the code-reading camera can accurately read the code and ensure that the verification process is completed accurately.

Description

technical field [0001] The invention relates to the technical field of code reading equipment, in particular to a code reading equipment capable of preventing mislabelling of cigarette turnover boxes. Background technique [0002] The current turnover box labeling equipment has the phenomenon of missed stickers, wrong stickers, and dropped labels, especially in cold winters. When the turnover box label is wrong, it will bring difficulties to the delivery of cigarettes, and the turnover box label check work is also more difficult. Complicated, the existing label checking is automated, using the conveyor belt for transportation and then using the code-reading camera to check, but because the conveyor belt is continuously conveying and the turnover box is in a moving state, when the code-reading camera is checked at this time, As a result, the code-reading camera cannot quickly read the content on the label, and the turnover boxes that have not been read will flow to the next p...

[0002] The current turnover box labeling equipment has the phenomenon of missed stickers, wrong stickers, and dropped labels, especially in cold winters. When the turnover box label is wrong, it will bring difficulties to the delivery of cigarettes, and the turnover box label check work is also more difficult. Complicated, the existing label checking is automated, using the conveyor belt for transportation and then using the code-reading camera to check, but because the conveyor belt is continuously conveying and the turnover box is in a moving state, when the code-reading camera is checked at this time, As a result, the code-reading camera cannot quickly read the content on the label, and the turnover boxes that have not been read will flow to the next process, resulting in omissions in the verification process. Other related prior art is based on barcodes. In the sorting drive structure, such as CN109335568A, a rotary drive device is used to realize the rotation of the package, and an external camera or barcode is used for sorting during the rotation process, but the contact area between the package / turnover box and the camera is relatively fixed, so it cannot be effectively To identify the barcode, a separate rotary drive structure is required, which is not suitable for assembly line package transportation. Other devices that can adjust the orientation between the package and the camera need to be equipped with a separate mediation mechanism. In addition, other existing technologies use Stalling the package when it is close to the camera position can improve the detection accuracy of the camera, but simply relying on increasing the shooting time of the camera and reducing the travel speed of the package cannot significantly improve the detection reliability. In view of this, we propose a method that can prevent Code reading equipment for mislabeled cigarette turnover boxes
