Automated assembly lines are widely used in agriculture, transportation, trade, services, and even households. They are crucial equipment for raw material transportation, as their proper functioning is key to the stability of the feeding system, directly impacting the safety and production efficiency of the entire production line. Due to the long-term use of automated assembly lines, various malfunctions may occur, making regular maintenance extremely important. How should you handle these issues? Do you remember the previous article on how to maintain automated assembly line equipment? Below, I share common fault analysis and troubleshooting for automated assembly lines:
(One) Cause and solution for the conveyor belt slip on the automated assembly line during operation:
1. Slippage can occur even with rapid startup. In this case, a slower startup is recommended. For squirrel-cage motors, it's effective to pulse twice before starting, which can also effectively overcome the slippage issue.
2. Overload on the conveyor belt, exceeding the motor's capacity can also cause slippage. The positive aspect of this slippage is that it acts as a protective measure for the motor. Otherwise, the motor may be damaged over time. However, for the operation, it is considered a slippage incident.
3. Initial tension is too low. Insufficient tension at the point where the conveyor belt leaves the roller causes the belt to slip. This issue typically occurs during startup.
4. Insufficient friction between the drive roller and the conveyor belt leads to slippage. The primary cause is often water on the conveyor belt or a humid environment.
(II) Solution for belt deviation issue during the operation of the assembly line equipment:
1. Adjust the position of the drive drum and the redirect drum. The adjustment of the drive drum and redirect drum is a crucial aspect of belt misalignment correction. Since a conveyor belt typically has at least 2 to 5 drums, the installation positions of all drums must be perpendicular to the centerline of the conveyor belt's length. Excessive tilt will inevitably cause misalignment. The adjustment method is similar to that of adjusting the roller group.
2. Installation and Adjustment of Heart Rollers: There are various types, such as intermediate shaft-type, four-bar linkage-type, and vertical roller-type, etc. The principle involves using barriers or rollers to rotate horizontally, generating lateral thrust to automatically center the belt, thereby adjusting the belt's deviation. This method is generally more reasonable when the total length of the assembly line equipment is short or when the equipment operates bidirectionally, as shorter assembly line equipment is more prone to deviation and harder to adjust.
3. Adjust the roller bearing assembly. When the conveyor belt of the production line runs off-center in the middle of the belt conveyor, the position of the roller bearing assembly can be adjusted to correct the offset; during manufacturing, both sides of the roller bearing assembly are machined into elongated holes for ease of adjustment. The specific method is to move the side of the roller bearing assembly facing the belt's forward direction forward if the belt is offset to one side, or move the other side backward.
