continuous signals that they can be requested by the computer programmed. The computer calculates the Romanian value according to the specification and evaluates it as described above. This makes it possible to make the necessary settings on the machine based on the received Romänewertes, thereby keeping the Romänewert to a minimum.

example 1

The device for determining the novels from Kammstuhlband and Kämmlingen consists of a arranged at the output of Kämmaschine measuring tube for Kammstuhlband 2. The pipe jacket is a laser 4. Opposite the laser 4 on the pipe wall, a SEV 5 is attached. It is followed by a known electronic follower 6.1, a known computer 7 and a known Meßwertanzeige 17. Outside of the combing machine at a central detection point for noils located on a manifold for noils 8 separating container 9 is arranged, the end of which has an air-permeable plate 14, the one temporary partition to the subsequent air-permeable collecting container 15 represents.

The separating container 9 lying in front of the air-permeable plate 14 has a tubular part 16, at the taper of which the pressure gauge 10 with limit contact is located. The air-permeable plate 14 can be tilted by the electronic latch 13. On the wall of the tubular part 16, a second laser 12 is arranged. Opposite the laser 12, another SEV11 is present on the pipe wall. It is followed by the electronic tracking device 6.2, which is connected to the computer 7.

The Kammstuhlband 1 is guided by a measuring tube for Kammstuhlband 2 so that in the transmission range 3, which is located between the laser source 4 and the SEV 5, in a given geometry, the total mass of the tape runs. Depending on the irradiated mass, a continuous signal is obtained, which is modified via the SEV 5 and supplied to the electronic tracking device 6.1. Upon detection of the mass of the noils via a manifold 8, these pass into the separating vessel 9. Upon reaching a preselected level of the positive pressure in the collecting container 9 increases to a certain value, which is signaled by the pressure gauge 10 to the Computer7. The detection of the discontinuous measurement value for the noils takes place in a similar manner as in the crib chair belt 1 via laser 12, SEV11, successor 6.2 with message to the computer 7. This triggers after detection of the measured value for the noils of the electronic interlock 13. The air-permeable disk 14 is released and the accumulated noils fall into the air-permeable container 15 for collection. After a predetermined time, the electronic latch 13 retracts the air-permeable disk 14 in the tubular member 16 and jams the incoming noils for the next measurement cycle.

In accordance with the polling cycle of the computer 7, the measured values are queried and stored. From the stored values, the computer 7 calculates the Roman value and passes it on to the measured value display 17, where it can be read, stored or fed to a known data acquisition system.

Example 2

The arrangement of the measuring tube for Kammstuhlband 2 with laser 4 and SEV 5 is in accordance with Example 1. At the entrance of the combing machine, the measuring tube for Rohstreckenband 19 is arranged. The laser 20 is located on the tube jacket. The SEV 21 is mounted opposite the laser 20 on the tube wall. The SEV 5 and 21 are followed by the electronic follower 22, which has a differential circuit in the input area. This electronic slave device 22, the computer 7 and the display 17 are analogous to Example 1 downstream.

The combed chair belt 1 is, as described in Example 1, passed through the Meßrohrfür Kammstuhlband 2 and the mass derived from the received signal of the SEV 5 continuously.

The raw strip 18 must be performed at the entrance of the combing machine through the measuring tube for Rohstreckenband 19. The detection of the mass is analogous to the determination of mass for the Kammstuhlband 1. The signal obtained from the laser 20 and the SEV 21 is continuously supplied to the electronic tracking device 22. The electronic follower 22 is constructed so that both continuous signals are prepared and can be queried in a programmed manner by the computer 7. According to the specification, the computer 7 calculates the Romanian value and evaluates it according to Example 1.

These two examples include the possibility to determine the Romanian value from the measured values for Kammstuhlband and Kämmlingen as well as from similarly determined values of Kammstuhlband and Rohstreckenband. If a Romanian value is available, it is possible for the beekeeping personnel to make the necessary adjustments to the machine in order to keep the Romanian value to a minimum.

By using the laser, a large part of the emitted radiation is concentrated from the outset on a very small wavelength range, which requires such intensity stability that it is not achieved by any conventional light source.

With a suitable SEV, it is possible to detect even very weak laser beams.

It is advantageous to choose a suitable diameter for the measuring tube, so that the required accuracy is achieved for the mass determination from the transmission method.

Advantageous in the application of the device according to Example 1 is the collection of novels from a number of combing machines with subsequent landfill. The measuring device for the Kammstuhlband 1 can be made transportable to determine the Romänewert successively on different Kammstühlen can. By applying the pneumatic transport via central manifolds and programmed removal, the mass of the noils for different combing machines can also be determined individually.

By preselecting a specific overpressure in the collection container, the mass of the noils can be kept constant almost for each measurement cycle and from the number of ejections of the jammed noils a statement about the mass of the noils can be derived.

The measurement of the mass of noils takes place in the separation vessel. When a pre-selected level is reached, the pressure is transmitted through the manometer to the computer. The recording of the discontinuous measured value for the noils takes place analogously as in the combed-belt conveyor via laser, SEV, follow-up device with message to the computer. After detecting the measured value for the noils, the electronic locking of the air-permeable plate is released and the noils enter the air-permeable container for collection and forwarding. The electronic interlock is performed in a certain predetermined time rhythm and corresponds to the measurement cycle.
