Embodiment Construction

[0020] In the case of a device for producing consumer goods, such as pastry consumer goods, composed of flowable, in particular foamed substances, the flowable substance is located in a container (1), preferably of pressure-resistant construction, the outlet end (2) of which opens into In the mutually coupled rotary piston pumps (3). Through the coupling of the rotary piston pump (3), the volume flows can be synchronized. The outlets (4) of the rotary piston pumps lead into nozzles (5), the outlets of which are each preceded by a closure (6). These closing mechanisms (6) are opened synchronously within a defined period. In this way, substances can be precisely dosed. Each closing mechanism (6) is provided with a return piston (7) which allows sucking back a part of the substance located in the outlet of the nozzle when the closing mechanism (6) is closed. In this way drips are prevented and a clean interruption of the substance is ensured. The torque exerted by the drive (...

Abstract

The invention relates to a device and a method for dosing compounds and especially foamed compounds to a dosage target location. The device comprises at least one unit (3, 5) having respective pumps (3) and nozzles (5) that are fluidically interconnected. The pump is a rotary pump (3) which comprises at least one rotary element (3b) arranged to rotate inside a pump chamber (3a).

Description

technical field [0001] The present invention relates to a device and method for dosing foamed substances. Such devices are used, for example, in the production of consumer goods, in particular for the filling and free filling of foamed substances under pressure. Foam substances to be dispensed are usually viscous substances from the fields of food, adhesives, insulating agents, etc., which are foamed with gas in a dissolved, molten or softened state, and are quantitatively distributed to the purpose by pumping and nozzle systems ground, and then hardened. Background technique [0002] Known filling systems fill or freely fill the charge of this substance in a time-controlled manner by opening / closing valves or by means of piston metering pumps. The substance is usually conveyed via one to two pressure lines into pressure-resistant containers (collectors). [0003] US 6,296,463 describes a device for applying polymer fibers from molten polymers (hot-melt adhesives) to subs...
