[Chinese Packaging Network News] The packaging process involves several key steps, including filling, wrapping, and sealing, along with various pre- and post-processing stages such as cleaning, feeding, stacking, and disassembling. Additionally, it may include tasks like measuring or printing dates on the package. Using automated packaging machinery can significantly boost productivity, reduce physical labor, support large-scale production, and meet hygiene and cleanliness standards. But what are the essential criteria for safe and effective packaging machinery? Let's explore them together.
1. Packaging machinery should clearly display product labels on a visible area and specify the main technical parameters required for normal operation, such as rated current and voltage, pressure, and heat temperature.
2. Safety requirements for hydraulic systems on packaging machines must comply with GB3766, while those for pneumatic systems must follow GB7932.
3. Electrical equipment on packaging machinery must meet the safety standards outlined in GB5226.
4. Any dangerous parts of the machine that could pose a risk to operators must have appropriate safety measures in place. Moving components like clamping and cutting mechanisms must maintain a safe distance to prevent injuries. Dangerous moving parts should be enclosed where possible, and any exposed rotating or moving parts must be protected. Protruding parts on moving components should be smooth or shielded.
5. Components that could become loose during operation must have reliable anti-loose mechanisms.
6. When waste is generated during the packaging process, appropriate exhaust systems must be installed to ensure operator safety.
7. If a motor is designed to rotate in only one direction, a clear directional mark should be placed on the motor or an accessible location.
8. If personnel enter a high-risk working area, safety protection devices must be installed. If the protective device fully isolates the working area, additional protections may not be necessary. Guards should be in place to maintain safe distances.
9. For packaging machines that require elevated operation, a platform meeting standard requirements, along with a ladder and handrails, should be provided.
10. The working system of the packaging machinery should include interlock protection to automatically stop the machine in case of failure.
11. A safety switch should be installed on all packaging machines. In emergencies, pressing this switch will immediately halt the machine to prevent accidents.
12. When the machine is in motion, a warning device should be in place to alert all personnel to leave the hazardous area promptly.
13. Clear and prominent signs for operation, lubrication, safety, and warnings should be present on the machine. Safety colors and signs must comply with GB2893 and GB2894, and the symbols used should adhere to relevant standards.
14. The safe operating mechanisms of the packaging machinery should be positioned where they are easily accessible and controllable by the operator.
15. For packaging machinery used in flammable or explosive environments, both mechanical and electrical components must have reliable protective measures and comply with applicable regulations.
By following these guidelines, manufacturers can ensure that their packaging systems are not only efficient but also safe and compliant with industry standards.
