Abstract
Description
Technical Field
[0001] This utility model relates to a detection device, and more particularly to a device for detecting missing labels. Background Technology
[0002] Currently, infusion labeling machines often encounter situations where labels are not applied or fall off after application. Existing production lines may misdetect these issues, leading to unlabeled bottles being packaged and affecting product quality. Summary of the Invention
[0003] The main purpose of this utility model is to solve the problem that labels often fail to be applied or fall off after being applied in the use of existing infusion labeling machines, and to provide a labeling failure detection device.
[0004] The label-missing detection device provided by this utility model includes a sensor, a reflector, a controller, and a cylinder. The sensor and the reflector are symmetrically mounted on both sides of the labeling machine conveyor belt. The controller is mounted on the frame at the bottom of the labeling machine conveyor belt. The cylinder is mounted on the support frame of the conveyor belt behind the sensor and the reflector. The sensor is connected to the controller, and the controller is connected to the cylinder. The sensor can transmit the collected data to the controller in real time, and the controller controls the operation of the cylinder according to the data transmitted by the sensor.
[0005] The sensor is an infrared sensor.
[0006] The controller is a PLC controller, and a solenoid valve is installed on the connection line between the controller and the cylinder.
[0007] The working principle of this utility model:
[0008] The leak-labeling detection device provided by this utility model is used so that after the infusion bottle has been labeled, it is conveyed by a conveyor belt to the position corresponding to the sensor and reflector. When the infusion bottle passes the sensor, the light reflected back by the reflector is used to determine whether there is a label. If the light is reflected back by the reflector, it means there is no label, and the sensor will transmit the information to the controller in real time. The controller will then instruct the cylinder to open via the solenoid valve on the connecting line, thus rejecting the infusion bottle without a label. If no light is reflected back, it means that the passed infusion bottle has a label, and the system will judge it as qualified and allow it to pass. The entire device is installed on the conveyor track, and the PLC controller completes signal acquisition and judgment to ensure that the leak detection work is completed.
[0009] The beneficial effects of this utility model are:
[0010] The label-missing detection device provided by this invention can greatly improve detection accuracy and reduce false detections. The controller provided by this invention is flexible and adjustable to adapt to different production needs. It can effectively prevent unlabeled infusion bottles from being packaged, ensuring product quality. Attached Figure Description

[0016] The label-missing detection device provided by this utility model includes a sensor 1, a reflector 2, a controller 3, and a cylinder 4. The sensor 1 and the reflector 2 are symmetrically mounted on both sides of the labeling machine conveyor belt 5. The controller 3 is mounted on the frame at the bottom of the labeling machine conveyor belt 5. The cylinder 4 is mounted on the support frame of the conveyor belt 5 behind the sensor 1 and the reflector 2. The sensor 1 is connected to the controller 3, and the controller 3 is connected to the cylinder 4. The sensor 1 can transmit the collected data to the controller 3 in real time, and the controller 3 controls the operation of the cylinder 4 according to the data transmitted by the sensor 1.
[0017] Sensor 1 is an infrared sensor.
[0018] The controller 3 is a PLC controller, and a solenoid valve 6 is installed on the connection line between the controller 3 and the cylinder 4.
[0019] The working principle of this utility model:
[0020] The leak-labeling detection device provided by this utility model is used so that after the infusion bottle has been labeled, it is conveyed by conveyor belt 5 to the position corresponding to sensor 1 and reflector 2. When the infusion bottle passes sensor 1, the light reflected back by reflector 2 is used to determine whether there is a label. If the light is reflected back by the reflector, it means there is no label, and sensor 1 will transmit the information to controller 3 in real time. Controller 3 commands cylinder 4 to open through solenoid valve 6 on the connecting line, thus rejecting the infusion bottle without a label. If no light is reflected back, it means that the passed infusion bottle has a label, and the system judges it as qualified and allows it to pass. The entire device is installed on the conveyor track, and the PLC controller completes signal acquisition and judgment to ensure the completion of the leak detection work.
