Description

Technical Field

[0001] This utility model relates to the technical field of adhesive spot detection in cigarette boxes, and more specifically, to an adhesive spot detection system for cigarette carton boxes. Background Technology

[0002] The ZB418 cigarette packaging machine is characterized by its high degree of automation and fast operation. The YB618 is the part of the ZB418 unit responsible for carton packaging. A key process in carton packaging is applying glue to the two side covers of the carton to ensure stable carton formation. The YB618 carton packaging machine uses a high-speed spray gun to apply glue dots to designated positions on the carton. During glue application, if glue dots are missing due to glue quality, nozzle blockage, or solenoid valve malfunction, subsequent processes lack relevant detection methods or devices for glue dots, directly resulting in defective products flowing into the next process, causing difficulties in product quality control. Currently, the solution to the problem of missing or misaligned glue dots on the YB618 is manual self-inspection, addressing issues only after they are discovered. This involves wasted manpower, low efficiency, and difficulties in quality control. Therefore, finding a convenient and accurate way to detect glue dots on cigarette cartons is of great significance.

[0037] This system further includes: an alarm device; the controller is connected to the alarm device in signal, and controls the alarm device to give an alarm when there are no glue points on both sides of the carton or the glue spraying is unqualified.

Visual inspection devices 5 (leftmost) and 6 (rightmost) are used to detect adhesive dots on the left and bottom left sides, and on the right and bottom right sides, respectively. When the controller detects a carton paper arrival signal, the four ultrasonic detectors start detecting simultaneously and transmit the results to the controller. When the controller detects a carton paper arrival signal, the two visual inspection devices start detecting simultaneously and transmit the results to the controller. The controller comprehensively judges the detection results. If all six detection results are true, it indicates that the carton has adhesive dots and meets the requirements, then it returns to the previous step. If any of the six detection results is false, it indicates that the carton adhesive dots are missing or the amount of adhesive does not meet the requirements. The controller activates the alarm to alert the operator and sends the result to the original control system of the packaging machine, which then controls the original machine's rejection mechanism to reject the carton. Meanwhile, all detection signals are displayed on the screen in real time. By comprehensively analyzing the detector signals, maintenance personnel can determine the specific location of the missing glue dots, providing a reference for further equipment maintenance.
