Problems solved by technology

[0004] The disadvantage with this known solution is that the operator has to make two adjustments which require two hands during the extrusion process
In addition to the laborious operation, a constant metering cannot be obtained with known extrusion devices when extracting the material

Embodiment Construction

[0035] In principle, the same parts are provided with the same reference numerals in the various figures.

[0036] exist figure 1 The extrusion device 11 for a storage container 6 containing material shown in has a receiving space 12 for the storage container 6 , a piston rod 13 movable relative to the receiving space 12 and an electrically actuable extrusion device 16. A pressure piston 14 is arranged on the end of the piston rod 13 facing the receiving space 12 for loading the storage container 6 or the material contained therein. When the extrusion device 16 is actuated, the piston rod 13 is pushed forward into the receiving space 12 and pressurizes the material present in the storage container 6 , so that the material is extruded through the extrusion opening 7 of the storage container 6 . The material contained in the storage container 6 includes one or more ingredients. In the case of a multi-component material, it is advantageous to provide a mixing element on the ex...

Abstract

The present invention relates to an extrusion device (11) for compound-containing containers (6), including a receiving chamber (12) for the container (6), a piston rod (13) which is displaceable relative to the receiving chamber (12), a motor (21) for moving the piston rod (13), a trigger member (26) for generating a control signal in response to actuation of the trigger member (26), and a control unit (31) for controlling the motor (21). The control unit (31) has a power module for connecting the motor (21) to a power supply (19), and a separate signal input which is electrically connected to the trigger member (26). The power module connects the motor (21) to the power supply (19) when the corresponding control signal is present at this signal input. The present invention further relates to a method for controlling such an extrusion device (11).

Description

technical field [0001] The present invention relates to an extrusion plant of the type described in the preamble of claim 1 for a storage container containing material. Furthermore, the present invention relates to a control method for such an extrusion device according to claim 8 . Background technique [0002] Such extrusion equipment is used to extract materials packaged in storage containers, such as stucco materials or sealing materials, at the application site. The storage container comprises, for example, a cartridge having one or more receptacles for one or more constituents of the material to be extracted, the material being arranged in the receptacles of the cartridge either directly or, for example, in a film bag. In addition, the term "storage container" also includes film bags filled with one or more components of the material to be extracted, which film bags are filled in a separate container or in a container provided on the extrusion device. [0003] From U...
