Weight Accounting System

Specifications
The weight accounting system is intended for calculation of bags and boxes with production, moving in a flow on conveyor belt.
Function
The weight accounting system is intended for calculation of bags and boxes with production, moving in a flow on conveyor belt at their transportation to the store room or shipment. The weight accounting system allows to eliminate finished product thefts, to accelerate the process of its shipment to the customer.
Structure
• weighing platform
• load cells
• weighing processor
• package of photoelectric sensor
• belt speed sensor
• portable boards (for store room, packing compartment and so forth)
Functions
• account of bags independently of the arrangement on the belt ("butt-to-butt", «overlapping», across the conveyor etc.);
• combined account of bags number (by weight, speed of movement of the conveyor belt, by length of bags etc.)
• control and exclusion of interference in system operation with conveyor blocking
• data storage about system operation (stoppings, errors etc.) in the computer journal of events
• control of the set quantity of bags at shipment to the customer transport (railcar, car)
Operating principle
The operating principle of the weight accounting system is grounded on weight measuring and speed of bag motion, moving on the weighing platform. Thus the bag presence on the belt is registered both on a signal from the platform load cells, and on a signal from the system photo sensors. The order of bag movement on the belt and their relative positioning does not influence on the exactitude of determination of bags number.
