DEVICE FOR MEASURING PROPERTIES OF A LONGITUDINALLY MOVED TEST SPECIMEN

Abstract A device for measuring properties of a longitudinally moved test material in a measuring cell, characterised in that the measuring cell is connected to a processor associated exclusively with the measuring cell and the measuring cell is fastened on a first carrier together with the processor, a connector to a central control system for a plurality of devices of this type and lines used to transmit signals from the measuring cell and in that the carrier is fastened to a production point of a spinning or spooling frame and has a line to a further carrier with a further measuring cell.

particular a digital signal processor (DSP), which has a plurality of inputs for connections to a plurality of ASIC modules. The first carriers with the measuring cells are connected by detachable connections, e.g. plug connectors, to the further carrier.
The advantages achieved by the device according to the invention are in particular that it is possible to dispense with a separate evaluation unit provided some distance away from the measuring head. There are therefore far fewer connections between measuring heads, evaluation units and control units of a spinning or spooling frame and so, because numerous connectors and printed-circuit boards are also dispensed with, operational reliability is increased. Since the device now comprises a low number of standardized parts, the manufacture and holding in storage of said parts by the manufacturer is likewise simplified. As larger piece numbers of each part are achieved, a greater accuracy and effort may go into the testing of said parts because specific test equipment for said purpose is worthwhile. Since the "intelligence" has been relocated in the measuring heads and decentralized, it is also only necessary to provide one cable from the measuring head to the production point and said cable carries digital signals, thereby making the system more fail-safe. The software is already stored in the measuring head and no longer has to be loaded there on demand.
Accordingly the present invention provides a device for measuring properties of a longitudinally moved test material in a measuring cell, characterised in that the measuring cell is connected to a processor associated exclusively with the measuring cell and the measuring cell is fastened on a first carrier together with the processor, a connector to a central control system for a plurality of devices of this type and lines used to transmit signals from the measuring cell and in that the carrier is fastened to a production point of a spinning or spooling frame and has a line to a further carrier with a further measuring cell.

There follows a detailed description of the invention by way of an example and with reference to the accompanying drawings in which :

2. The device according to claim 1, wherein the measuring cell and the processor are disposed together on a first carrier (3, 4) and the processor (6, 13) has one output (10, 15) for digital signals.
3. The device according to claim 2, wherein a further carrier (18) is provided, to which at least one first carrier (3) with a measuring cell (1) is fastened.
4. The device according to claim 3, wherein disposed on the further carrier (18) are first carriers (3, 4) with measuring cells (1, 2), which effect various types of measurement.
5. The device according to claim 4, wherein, as measurements, one each from a group comprising optical measurement of the cross section, capacitive measurement of the mass and measurement of impurities are provided.

6. The device according to claim 1, wherein associated with each measuring cell (1,2) as a processor (6, 13) is a so-called ASIC module which, irrespective of the measuring cell and its measuring operation, is of the same construction.
7. The device according to claim 6, wherein the ASIC module has inputs (30) for analog signals and one output (10, 15) for digital signals.
8. The device according to claim 3, wherein, the first carrier (3) comprises a computer (7) in the form of a digital signal processor, which has a single output (11) for signals from measuring cells (1, 2) on the further carrier.
9. The device according to claim 6, wherein the measuring cell and the ASIC module
are permanently connected to one another.
10. A device for measuring properties of a longitudinally moved test material in a
measuring cell substantially as herein described with reference to the accompanying
drawings.
