Abstract
A method for evaluating a wear condition of a component of a rotary press includes providing the rotary press which includes the component. Values of at least one of: (i) ejection forces acting on the ejector cam during operation of the rotary press; and (ii) vibration frequencies occurring during operation of the rotary press are measured. The wear condition of the component of the rotary press is evaluated based on the measured value.
Claims16
A method for evaluating a wear condition of a component of a rotary press, comprising:
- providing the rotary press comprising,
- a rotor configured to be rotated by a rotary drive, wherein the rotor comprises,
- an upper punch guide configure to guide upper pressing punches,
- a lower punch guide configured to guide lower pressing punches, and
- a die plate arranged between the upper and lower punch guides and defining a plurality of cavities, wherein the upper and lower pressing punches interact with the plurality of cavities of the die plate,
- a filling apparatus configured to dispense a powder material into the cavities of the die plate,
- a pressure apparatus configured to cooperate with the upper and lower pressing punches to press the powder material in the plurality of cavities into pellets, and
- a plurality of control cams configured to cooperating with the upper and lower pressing punches for controlling an axial movement of the upper and lower pressing punches, wherein the plurality of control cams includes an ejector cam configured to control the lower pressing punches to eject the pellets from the plurality of cavities;
- measuring values of at least one of:
- (i) ejection forces acting on the ejector cam during operation of the rotary press;
- and (ii) vibration frequencies occurring during operation of the rotary press;
- and
- evaluating the wear condition of the component of the rotary press based on the measured values.
