Abstract

A weighing arrangement comprising an infeed for product material to be weighed and at least one dosing mechanism for controlled conveying of product material portions from said infeed to a weighing system. The dosing mechanism comprises a motor-driven transport screw formed as a helically shaped rod positioned in a trough for conveying the product material from the infeed to the weighing system and a control unit for controlling the motor in order to deliver a desired portion of product material to the weighing system. This weighing arrangement makes it possible to provide a well-defined conveyance of product materials, which are not suited for vibrational conveyance.

Description

technical field

[0001] The present invention relates to weighing equipment, such as a multihead weigher, comprising a feeder or storage hopper (both feeder) for product material to be weighed, and controlling the quantity of product material conveyed from said feeder to a weighing system at least one dosing mechanism. Background technique

[0002] This known weighing device employs a dosing mechanism or dosing mechanism comprising a vibrating plate arranged as a trough for conveying the required amount of product material to the weighing system, the vibrating plate conveying the product material from the feeder to the weighing system, and control the timeliness and intensity of vibration. This type of weighing equipment can be used for a wide variety of product materials as long as the product material can be conveyed by sufficiently stable vibration and in an organized manner. Another way of conveying the required quantity of product material to the weighing system is to ...
