Labeling machines plays a vital role in modern industrial production. Whether in food, medicine, cosmetics or electronics industries, accurate and efficient labelling is key to getting products into the market. Labels not only carry basic product information, but also influence brand image and market circulation. The stable operation and accurate labeling of labeling machine directly affect production efficiency and product quality. However, newly installed labeling machines or those that have been in use for some time need debugging to ensure optimal performance. This paper will discuss in detail the problems related to the debugging of the labeling machine and provide comprehensive guidance to the relevant personnel.
What do you require to do before using labeling machine?
Equipment Inspection
- Appearance Inspection: Check carefully for damage, deformation or cracks in the outer casing of the labeling machine. Check that all connections are secure and screws or nuts are loose or missing. Also, inspect the surface of the machine for oil, dust and other impurities to ensure a clean appearance. Not only does this affect the machine's aesthetics, but there may also be safety hazards. For example, a loose shell may cause vibrations during use, affecting labeling accuracy. Please refer to the Official Maintenance Guide of the [Brand] Label Machine, which details the main points and standards of the inspection and provides a clear basis for the inspection.
- Mechanical Component Inspection: a complete inspection of all mechanical components of the labeling machine. Check that transmission components, such as belts and chains, are properly tensed. Too loose or too tight can affect normal operation and labeling quality. Check the lubrication of bearing, gear and other components to ensure proper lubrication and reduce wear and noise. For example, insufficient bearing lubrication of bearings can cause the machine to operate erratically and cause jitters, which can affect the accuracy of label application. Electrical
- System Inspection: The stable operation of electrical system is very important to the normal operation of labeling machine. Check that power supply circuit is properly connected and that there are no signs of damage or aging. Verify the voltage and current of each electrical element using a special electrical testing tool. For example, check that the contact points of components such as contactors and relays are correct and that there are no signs of corrosion or oxidation. Electrical system failures can lead to problems such as equipment failure, instability or malfunction.
Tools and Material Preparation
- Common Debugging Tools: A complete set of debugging tools is essential for smooth debugging of labeling machines. Common debugging tools include screwdrivers, wrenches, multimeters and vernier calipers. Screwdrivers and wrenches are used to remove and install components and adjust screw tightness; multimeter is used to test electrical system parameters such as voltage, current and resistance; and vernier calipers are used to accurately measure label size and position. The book "Debug and Maintenance of Industrial Automation Equipment" introduces in detail the kinds and methods of commonly used tools for labeling machine debugging.
- Labels and Object Material preparation: Prepare the same label and item samples as in actual production. Ensure label quality meets requirements without breakage, wrinkle or distortion. The surface of the labeled object should be smooth and clean, free of oil, dust and other impurities, preventing poor adhesion. At the same time, prepare a sufficient number of labels and items for testing and adjustment as required. _ the Automation Equipment Network _[Official homepage] Many professionals have shared their experiences with the preparation of machine commissioning materials for practical use.
Operator training
Familiar with labeling machine operating manual: operators should read the labeling machine's operating manual carefully to understand the equipment's basic structure, operating principle, operating procedures and safety precautions. The operating manual is an authoritative document provided by the equipment manufacturer. It contains detailed technical specifications and operating instructions. It is an important basis for the debugging and operation of operators. For example, by reading the operating manual, operators can learn key information such as the maximum sticker speed of the device and the applicable label size range.
Know the commissioning process and safety precautions: Before debugging, operators must have a clear understanding of the commissioning process and steps and operate in the prescribed order. At the same time, they must strictly follow safety precautions to ensure their safety and the proper functioning of their equipment. For example, when debugging an electrical system, the power supply must be turned off to avoid electrocution. Care must be taken to prevent finger compression when adjusting mechanical components. ISO 10015, published by the International Organization for Standardization (ISO), defines the content and requirements of training for operators of industrial equipment and can be applied to the training of sticker operators. In addition, the training materials for operators provided by sticker manufacturers generally include detailed debugging procedures and safety precautions.
In the process of debugging the sticker, how to calibrate the placement and angle of the sticker?
Calibration placement position
Calibration of the horizontal position of the label: Calibration of the horizontal position of the label using a laser locator or ruler. First, place an object under the outlet of the labeler and mark the desired horizontal position on the object. Start the labeler and apply it to the object. Observe the deviation between the actual horizontal position and the marked position. Adjust the feed mechanism or outlet of the labeling machine to ensure the required horizontal position. For example, if the label is biased to the left, the feed mechanism component is adjusted to the right.
Vertical position calibration: use ruler or height gauge for vertical position calibration. Marks the desired vertical position on the object. After applying the label, observe the deviation between the actual vertical position and the marked position. Adjust the pressure mechanism or outlet of the sticker to ensure correct vertical position. For example, if the label is too low, raise the outlet or pressure mechanism appropriately. Correction of label Angles
Label rotation angle correction: label rotation angle correction requires the use of tools such as angle gauge. Fixed the object to be labeled in the labeling machine. After labeling, the angle of rotation of the label relative to the object is measured with an angle gauge. According to the measurement results, the rotary mechanism or related parameters of the labeling machine are adjusted to reach the specified rotation angle of the labeling machine. For example, if the label rotates clockwise at an angle, adjust the rotation mechanism counterclockwise to correct it.
· Label Tilt Angle Calibration: To correct the label's tilt angle, first place the object on a horizontal surface. After applying the label, observe the tilt of the label relative to the water level. Measure the inclination with an angle ruler. Then, adjust the labeling machine's guide mechanism or label imprint mechanism so that the the label's tilt angle is within the specified range. For example, if the label leans to the upper right, adjust the guide mechanism to tilt it to the lower left.
Points to note during the calibration process
- When correcting the position and angle of label stickers, individual measurements may be subject to errors due to factors such as accuracy of measuring tools and human-machine interaction. Therefore, multiple measurements should be taken and the mean should be used as the final result to improve calibration accuracy. For example, when measuring the horizontal position of a label, three to five measurements can be taken and the average calculated.
- Consider the impact of environmental factors: Environmental factors such as temperature and humidity may influence labeler calibration results. For example, temperature fluctuations can cause material to expand and contract, affecting the placement and angle of labels. Calibration shall be carried out under stable environmental conditions and environmental parameters shall be recorded. If environmental conditions change, recalibration or correction of the calibration results required. refer to Mechanical Engineering Journal,Mechanical Design and Manufacturing, which contains research papers on labeler calibration technology and provides specific methods and examples of environmental considerations. In addition, detailed calibration procedures and techniques are provided by reference to the technical documents of the major labelling companies, such as the White Paper on Labelling Techniques for [company name].
How should performance testing and troubleshooting be carried out after the labeling machine test run?
Performance testing
- Dynamic testing of the labeling machine: Set the labeling machine to maximum speed and operate continuously for a period of time (e.g. 30 minutes). Record the number of labels successfully applied during this period. The actual labeling speed is calculated based on the number of records and running times. The nominal speed of the actual sticker is compared with the nominal speed of the machine to determine whether labeling machine meets design requirements. For example, a machine with a nominal speed of 100 tags per minute and an actual test speed of 95 tags per minute is considered acceptable within tolerance.
- Label accuracy test: Measure label position deviation on the applied object using a high-precision measuring tool such as vernier calipers or micrometer. Measure the label's horizontal and vertical bias, as well as rotation angle deviation. The measurement results compared with the machine's specified accuracy requirements to determine whether the labeling machine's accuracy was up to standard. For example, if the machine specifies a horizontal position deviation of not more than ±0.5mm, and if the actual measurement deviation is within this range, the machine passes. With reference to GB/T [Standard Number], such as labeling machine performance test method, the labeling speed, accuracy, stability and other performance indicators of the test method and requirements are clarified. At the same time, the paper draws on the testing reports and cases of authoritative testing institutions in the industry to understand the specific operation and data analysis methods of labeling machine in actual production.
- Stability test of labeling machine: run the labeling machine continuously for 8 hours to see if the labeling machine malfunctions, abnormal noise or vibration. Check the quality of label application regularly and record the change of label speed, accuracy, etc.. If the machine is stable over a long period of time, all parameter variations are within acceptable range, and the labeling machine demonstrates good stability.
Troubleshooting
Analysis of common malfunctions and causes of labeling machines: various malfunctions may occur in the process of labeling machines, such as inaccurate labeling, wrinkling and failure to start. Inaccurate labeling may be due to wear and tear on mechanical components, electrical system failure or inaccurate calibration. Wrinkled labels may be due to poor label quality, excessive pressure on label embossing mechanisms or mismatch in label feed speeds. The failure of the device to start may be due to a power outage, damage to electrical components or activation of safety devices. Refer to the sticker manufacturer's troubleshooting manual, which lists fault symptoms, causes and solutions.
Procedures and Methods for Handling Fault of Sticker When a sticker malfunctions, a specific troubleshooting procedure shall be followed. First, look for the equipment's fault symptoms and record information such as when and how often the failure occurred, and any accompanying symptoms. Then, step by step, examine the components and systems according to symptoms and possible causes. For example, if the machine doesn't start, check the power supply first, then check for damage to components such as fuses and contactors in the electrical control cabinet. In the process of troubleshooting, special test tools such as multimeter or oscilloscope are used to measure and analyze electrical parameters. If you are unable to resolve this issue yourself, contact the equipment manufacturer or a professional repair technician immediately.
