Components of Tablet Inspection Machine
Hopper
The hopper in a tablet inspection machine is where the tablets are initially loaded. It serves as a bulk feeder and can hold many pills at once. The hopper’s capacity depends on the machine’s size and the tablets being inspected. It helps prevent overloading and ensures the tablets are fed consistently into the next stage of the process.
Magnetic Vibrator
After the tablets have been loaded into the hopper, they are transferred to a magnetic vibrator. The magnetic vibrator ensures that the pills are evenly distributed and separated from each other. It also removes any excess powder or debris from the tablets, reducing the risk of false rejects during inspection.
Conveyor Belt
Once the tablets have been separated and loaded onto the conveyor belt, they are transported to the inspection area. The conveyor belt plays a critical role in maintaining a constant flow of tablets and preventing any jams or blockages that could occur.
Motor
The motor is responsible for powering the conveyor belt and regulating the speed of the tablets as they move through the inspection area. It is an essential component of the tablet inspection machine, ensuring pills are carried consistently, which helps reduce inspection errors.
Two-Foot Switches
Two-foot switches provide an additional safety feature that helps prevent operator injury. They are located at either end of the conveyor belt and must be activated simultaneously for the machine to run. This feature ensures the operator’s hands are free from moving parts, making the overall process safer.
Inspection Lamps
Inspection lamps are vital in the tablet inspection process by providing illumination. The lights help to highlight any defects that may be present, making it easier for the operator to identify and reject them.
Discharge Chute
The discharge chute is located below the inspection area and collects the tablets that have been inspected. Any defective tablets are rejected and directed toward the rejection tray, while those that meet the criteria for quality are redirected into a collector drum.
Collector Drum
The collector drum collects all accepted tablets and sends them for further processing or packaging. It plays a crucial role in ensuring the quality of the pills and reducing waste.
Rejection Tray
The rejection tray collects and separates all the rejected tablets from the accepted ones. It provides essential feedback to the operator on any underlying issues that may be present in the manufacturing process.
Control System
The control system is the brain of the tablet inspection machine. It monitors and controls all of the machine’s components, including the hopper, magnetic vibrator, conveyor belt, motor, two-foot switches, inspection lamps, discharge chute, collector drum, and rejection tray. It plays an essential role in ensuring that the machine functions correctly and that the tablets are inspected to the highest standard.
