Problems solved by technology

Since each individual screw element is suitable for a specific function, such as a conveying function or a kneading function or a mixing function and the like, which are each caused by the specific external geometry of the elements, every wrong insertion will lead to the inability to achieve all Desired work result, especially if a wrongly inserted screw shaft can be installed
[0004] Although the operator shows a high degree of care and responsibility when inserting or installing the extruder screw, in principle it is difficult to rule out inserting errors, because this is a purely manual work

Embodiment Construction

[0038] figure 1 A device 1 according to the invention for checking the configuration of an extrusion screw 2 is shown. The extrusion screw 2 comprises a shaft 3 on which screw elements 4 are pushed on in seemingly arbitrary order. The shaft has an external toothing, and each screw element 4 has a corresponding internal toothing in the area of ​​its bore 5 , wherein the external toothing and the internal toothing mesh with each other, whereby a torsionally fixed connection is produced. The principle construction of such plug-in extrusion screws has long been known.

[0039] In the device 1 according to the invention, each screw element 4 has a storage element 7 on its end face 6 , here in the form of a transponder 8 . Each transponder 8 contains stored information which identifies the respective screw element 4 .

[0040] In principle, a general distinction is made between three different screw element families, namely the conveying elements as well as the mixing elements an...

Abstract

A device for checking the construction of an extruder screw having a shaft and screw elements that are to be pushed or have been pushed one after the other onto the shaft in a defined sequence. Each screw element has an element-specific external geometry. A recording device being provided for determining information concerning the sequence of the screw elements that are to be pushed on or have been pushed on and for comparing the information determined with target information, which directly or indirectly describes the target sequence.

Description

technical field [0001] The invention relates to a device for checking the configuration of an extrusion screw comprising a shaft and screw elements which are to be pushed onto the shaft or have been pushed onto the shaft successively in a defined sequence, wherein each screw element has an element Unique external geometry. Background technique [0002] Extruders are known for processing substances which are processed in working parts or cylinders by one or more extrusion screws rotating there. These are merely examples of plastic substances which are melted and compounded in an extruder for subsequent further processing, for example for forming plastic pellets or within the framework of injection molding for the production of components and the like. Furthermore, pharmaceutical products are mentioned by way of example, which are used for processing pharmaceuticals, for example in the form of tablets. Here the corresponding substances are processed in cylinders by means of ...
