Description

one

The invention relates to dispensing devices used to dispense bulk and liquid materials.

There are portions of dispensers containing a weighing system, a weigh-in bucket, main and auxiliary feeders and a control system. After the main dose is delivered, the feeder is closed with a valve from the electromechanical control system and the valve is opened for filling 1.

This dispenser has low productivity.

The closest to the technical essence of the invention is a dispenser containing a hopper with openings for loading a volumetric control chamber and small chambers with a volume equal to 1% of the nominal weight of a batch, a load receiving device and a device for determining the underweight and the required number of small filling cells 2.

This dispenser does not dispense various materials.

The purpose of the invention is to provide high-performance dosing of materials with different bulk weights.

The goal is achieved by the fact that in the proposed dispenser the automatic control unit is equipped with a block of infinitely variable signal transducer proportional to the volume mass of the material being produced, and the feeder chambers are made of different volumes in accordance with the volume weight of the metering materials.

FIG. 1 schematically shows the proposed dispenser; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a graph of changes in the dependence of the volume of the filling of the bulk mass of the material being weighed.

The discrete weighting dispenser consists of a booker 1 with one large feed opening, adjustable volumetric

pre-portioning chambers 2, feeder 3 of bulk filling consisting of chambers of different volume, bucket 4, lever 5 with counterweight 6, converter 7, arresting device 8, signal setting unit 9, unit 10 for determining the magnitude of underweight and number of power chambers which carries out the filling of the actuator control unit 11, the actuators 12, 13, 14 and the suspension funnel 15.

When dispensing with a volumetric chamber 2, a pre-portion with an underweight of 3-5% of the nominal is loaded into the bucket 4, which is locked by the arresting device 8 to the position corresponding to its static

position. At the end of the perssyik; the pre-ision is unzipped and the stage 5 and after the expiration of the time NOT. The YCHO block 10 determines the missing weight from the signal received by the converter 7 and the feed control cameras that rest simultaneously with the bucket 4. The node also gives commands to the mechanisms, causing the arresting device 8 to stop the lever 5, mechanism 12 opens the bottom of the bucket, and the mechanisms 14 empty the required supply feeder chambers, and the predetermined dose of material through the suspension funnel 15 enters the bag 16.
