Claims
- 1. A method of operating a pelletizing machine provided with a rotatable matrix disc and plungers, the method comprising the steps of supplying values corresponding to maximum pressing forces of the plungers to a computer for comparison with nominal value limits and actuating a sorting out device should the maximum pressing forces be outside the nomal value limits; detecting a position of the matrix disc by an angle pulse transmitter formed as a coded disc and releasing pulses by the latter to supply the pulses to the computer for association to the values of the maximum pressing forces for associating an error in the manufacture of the pellets with the corresponding plungers; supplying by the angle pulse transmitter a circumferential pulse to the computer during each revolution of the matrix; and orienting the angle pulse transmitter with the zero position on pressing rollers of a main pressing station.
- 2. A method as defined in claim 1, wherein the pulses are supplied as separate pulses by the angle pulse transmitter from at least two pressing stations to the computer.
- 3. A method as defined in claim 1; and further comprising the step of controlling by the computer of the sorting out deflector behind a main pressing station.
- 4. A method as defined in claim 1; and further comprising the step of orienting the angle pulse transmitter with a zero position on pressing rollers of a main pressing station.
- 5. A method as defined in claim 1; and further comprising converting by the computer of detected angle pulse in a number of matrixes of the matrix disc.
- 6. A pelletizing machine, comprising a rotatable matrix disc; plungers whose maximum pressing forces are supplied for evaluation; and a computer to which the maximum pressing forces of the plungers are supplied for evaluation; an angle pulse transmitter formed as a coded disc signal transmitter supplying pulses released by the matrix disc during its rotation into said computer for an association to measured maximum pressing forces, said angle pulse transmitter being cinnected with said computer; and a second computer to which said first mentioned computer supplies corrected signals and in which additionally maximum determined pressing force values are supplied.
- 7. A pelletizing machine as defined in claim 6, wherein said matrix disc is provided with a drive, said drive being provided with said coded disc signal transmitter.
- 8. A pelletizing machine as defined in claim 7; and further comprising a sorting out deflector and a control unit provided for said sorting out deflector and connected with said second computer.
