[0027] Example 1
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vertical labeling machine for syringes is suitable for labeling product packaging with external protrusions, such as syringes. In this embodiment, the product packaging material is a syringe. It includes a frame 1, on which a feeding device 2, a feeding dial 3, and a labeling star-shaped turntable 4 are sequentially arranged. The labeling star-shaped turntable 4 has a label dispensing device 5 and a label rolling device 6 arranged on its side. The feeding device 2 includes a feeding clamp 21, and a driving device 25 is arranged at one end of the feeding clamp 21. The driving device 25 is connected to a conveyor chain 26. The feeding clamp 21 is provided with a feeding... The feeding clamp adjustment device 22 is configured to adjust the distance between the clamps, so that the feeding device 2 can better adapt to the feeding of syringes of different sizes. The label dispensing device 5 is configured to attach the label to the product (syringe) packaging. The label rolling device 6 is configured to roll the label output by the label dispensing device 5, so that the label can be firmly adhered to the product material through the rolling of the label rolling device 6.
[0029] In this embodiment, a photoelectric detection device 23 and a reflector 24 are provided on the feed clamp 21, and the photoelectric detection device 23 and the reflector 24 are located on the upper and lower sides of the feed clamp 21. Preferably, a photoelectric detection device 23 and a reflector 24 are provided at both ends of the feed clamp 21 to accurately determine whether the syringe has reached the designated position. The photoelectric detection device 23 emits light, and when the light is reflected back by the reflector 24 and received by the photoelectric detection device 23, it indicates that the light path is normal. If a syringe passes through the feed device 2, it will block the light, causing a change in the light signal received by the photoelectric detection device 23, thereby detecting the presence of material. In this way, it is possible to accurately determine whether the syringe has reached the designated position, so as to control the operation and stop of the feed device 2 and realize automated feeding control. Based on the time and frequency of light blocking detected by the photoelectric detection device 23, the moving speed and position of the material can be determined. When multiple syringes pass through in sequence, the number of times the light is blocked can be counted to count the number of syringes fed, which facilitates the monitoring and management of the production process and ensures the accuracy of the feeding quantity. When the photoelectric detection device 23 detects abnormal light changes, such as continuous obstruction or no material detected for an extended period, it can issue an alarm in a timely manner to remind operators to conduct an inspection. This helps to promptly detect potential blockages or jamming issues in the feeding device 2, avoiding quality problems during production, such as errors in subsequent processing caused by missing syringes or discontinuous feeding. It also ensures the safe operation of the production equipment and prevents equipment damage caused by malfunctions.

[0039] Example 2
[0040] The difference between this embodiment and Embodiment 1 is that the vertical labeling machine further includes a PLC controller 9 (Programmable Logic Controller).

[0041] The working principle or operation process in this implementation is as follows: Material is supplied through the feeding device 2. Driven by the drive device 25, the conveyor chain 26 rotates, thereby driving the syringe clamped between the feeding plates 21 to be conveyed to the feeding dial 3. The feeding dial 3 then precisely distributes the material to the labeling star-shaped turntable 4. The printing device 56 prints the label information onto the label, and the label dispensing device 5 is responsible for affixing the label to the designated position on the syringe surface. The rolling device 6 applies rolling pressure to the label, ensuring that the label is tightly and firmly affixed to the material. The label information detection device 10 is responsible for detecting the label information, the labeling detection device 7 is responsible for position detection, and the rejection device 8 rejects unqualified labels, while qualified labels are output through the qualified product outlet 83.
[0042] The beneficial effects of this embodiment are as follows: by setting up a PLC controller, the program can be quickly modified to adapt to diverse needs; it has a complete self-diagnostic function, which can monitor the working status of the labeling machine in real time.
