Abstract:
The present disclosure relates to a weighing and transport device and a method for transporting and detecting mass flow rates of bulk material. In filling cycles, a weighing container is closed at its upper inlet and lower outlet, whereupon bulk material id fed directly to the weighing container. In weighing cycles, the upper inlet and the lower outlet are opened and the bulk material is discharged via an impact means, e.g., an impact cone. A level sensor measures a filling level of the bulk material in the weighing container; an actuator serves to close the upper inlet and the lower outlet. Preferably, the lower outlet is closed by the impact means, and the upper inlet is closed by raising the weighing container against a support means, where, in particular, a common adjustment can be carried out via the actuator.
Abstract:
Automatic machine for inserting in an homogeneous and metered manner into stuffed articles of various kind, in particular but not exclusively clothes articles, of stuffing material of various kind such as polyester fibers, plumage and the like, adapted to maintain the heat into the same articles. Machine into which it is introduced the stuffing material contained into bags or containers provided by the producing and transforming firms of the same material, and such material is introduced and collected into a collecting and stocking container, from which the material is let to fall into underlying weighing containers communicating with the container, for weighing the material by loading cells, and the weighed material is subsequently transferred into an injection station adapted to insert and inject the same material into the pockets or spaces of each clothes article. There are described in detail the conformation of these component parts and the remaining operative component parts of the machine, as well as all the operations which are carried out for setting and controlling the different operative cycles of the machine.
Abstract:
A dispensing system is disclosed for dispensing material from multiple hoppers to a convey line. As disclosed, material is dispensed from the hoppers via operation of a variable rate feed device. The application discloses a controller device configured to utilize input from a first load cell for a first hopper and a second load cell for a second hopper to determine a mass flow rate to increase or decrease the feed rate so that the flow rate of material dispensed into the convey line matches a set mass flow rate of material. In the embodiments disclosed, the hoppers include hoppers connected in series to the convey line and hoppers connected in parallel to the convey line. The controller device determines the mass flow rate based upon input from one of the first or second load cells during a first time period and both the first and second loads cells during a second time period for different operating phases of the system.

Abstract:
A method for measuring liquid to be transferred from a container or containers to a measurement pot includes the steps of: determining an initial degree of opening of the valve for controlling flow-rate of the liquid from the container to the pot based on the valve's flow-rate characteristics and an arbitrarily chosen set value; opening the valve by the initial degree of opening; detecting the actual amount of liquid that has flowed into the pot; determining a next degree of opening of the valve based on the actual measurement and the set value; and changing the degree of opening of the valve to the next degree of opening. The determination of the degrees of opening of the valve is based on fuzzy control, which uses a fuzzy inference from the set value and actual measured value. An apparatus for measuring liquid for use in a liquid mixing apparatus uses the above-mentioned method.
