Abstract
Apparatus for checking a state of a machine part of a shaping machine, comprising an evaluation unit, at least one power loss sensor for ascertaining a power loss measurement signal which is representative of a power loss in and/or at the machine part, and at least one movement sensor for ascertaining a movement measurement signal which is representative of a movement of the machine part, wherein the evaluation unit is adapted to compute a damage indicator for the machine part from the power loss measurement signal and from the movement measurement signal.
Claims33
An apparatus for checking a state of a machine part of a shaping machine, comprising:
- an evaluation unit,
- at least one power loss sensor for ascertaining a power loss measurement signal which is representative of a power loss in and/or at the machine part, and
- at least one movement sensor for ascertaining a movement measurement signal which is representative of a movement of the machine part,
- wherein the evaluation unit is adapted to calculate a damage indicator for the machine part from the power loss measurement signal and from the movement measurement signal,
- wherein the power loss denotes a difference between power input and power output, and
- wherein the power loss is based on heat flow and is determined by a temperature measurement or is calculated as a difference between supplied electrical power and delivered mechanical power.
A molding machine or injection press comprising:
- an apparatus for checking a state of a machine part of the molding machine or injection press,
- an evaluation unit,
- a wear sensor for ascertaining a wear of the machine part and communicating a wear measurement signal which is representative of the wear that is ascertained to the evaluation unit, and
- an open-loop or closed-loop control unit in signal-transmitting relationship with the evaluation unit for open-loop or closed-loop control of the molding machine or injection press,
- wherein the evaluation unit is adapted to calculate a damage indicator for the machine part from the wear measurement signal, and
- wherein the open-loop or closed-loop control unit is adapted to provide for open-loop or closed-loop control of the molding machine or injection press in dependence on the damage indicator communicated by the evaluation unit to the open-loop or closed-loop control unit and is further adapted to provide for possible shutdown of the machine part.
