Study Notes
Conveyor Hazards
- High risk of cuts and body parts getting caught in conveyor systems.
- Hazards include pressure from bursting/falling bottles, falling bottles, and contact with running equipment.
Main Components
- Key elements of the conveyor include guide rail, stainless steel frame, drive motor, and slat chain.
Guide Rail Functionality
- Prevents bottles from falling while guiding them without metal-to-glass contact to avoid scratches.
- Essential for directing bottle flow without excess pressure to prevent jams.
- Features a parabolic curve to gradually direct bottles to the next conveyor, ensuring equal pressure distribution.
Transfer Mechanism
- Utilizes a fixed-speed setup with a gear ratio adjusted by a frequency converter for electronically controlled speeds.
Sensors and Detection
- Includes "cloth hanger" sensors, photocells for bottle presence detection, and system responses for a full line.
Lubrication System
- Requires 1%-2% diluted liquid soap as lubricant on the conveyor chain to minimize friction.
- Insufficient lubrication can lead to jams, motor overloads, and rejects due to foam accumulation, which may interfere with bottle inspection.
Chain Conveyor Inspections
- Regular inspection of chains, sprockets, and entire conveyor system is critical for preventing malfunctions and addressing issues proactively.
- Essential inspection topics include checking chain sag, measuring elongation (maximum 3% elongation), and unusual wear patterns.
Specific Inspection Guidelines
- For stainless steel chains: replace if elongation exceeds 20 links = 784mm, with a new measurement of 20 links = 762mm.
- For plastic chains: maximum elongation over 20 rows should not exceed 3% (from 508mm to 523mm).
Wear and Clearance Checks
- Monitor clearance between chain links, dead plates, and turntables, along with checking for excessive wear on top plates and sprockets.
- Inspect for dirt buildup in sprocket tooth pockets and misalignment of flanged wheels.
Lubrication and Operational Checks
- Verify the lubrication system's function, the condition of curve glide strips, return rollers' rotation, and drive shaft bearings.
- Assess the operational state of drive and reducer components for optimal performance.
ECOPUSH Parameters
- Essential parameters include start position, stroke, and acceleration for effective operation.
