Abstract

Production machine (1) with at least one signal output (4, 5, 6, 7, 9, 31, 33, 35) with the capability of transmitting production status information to a production control system or production monitoring system (32, 34, 39).

Signal outputs (4, 5, 6, 7, 9, 31, 33, 35) of the production machine (1) are picked up and the statuses of the signal outputs (4, 5, 6, 7, 9, 31, 33, 35) are passed on via data connections (10, 11, 12, 13, 14) to an operator console (15).

The product status information obtained in this way is transmitted together with the information input manually by an operator via a data connection (16, 17, 18, 20, 31) to a computer system (32) for evaluation.

Claims

1. A production machine (1, 28) with at least one signal output (4, 5, 6, 7, 9, 31, 33, 35) for transmitting production status information to a production control system or production monitoring system (22, 24, 39), it being possible for production status information to be generated in accordance with events picked up automatically on the production machine (1, 28) and with manual inputs of an operator of the production machine (1, 28).

2. The production machine (1, 28) as claimed in claim 1, characterized in that a keypad or a switch array (25, 34) is provided for the manual input.

3. The production machine (1, 28) as claimed in claim 1 or claim 2, characterized in that a touch-sensitive screen (43) is provided for the manual input.

4. The production machine (1, 28) as claimed in one of the preceding claims, characterized in that signals can be picked up from sensors (4, 5, 6, 9, 31, 33) of the production machine (1, 28), in particular sensors (4, 9, 31, 33) for determining the filling status of buffer zones (3, 8, 30, 32), sensors for measuring pressure (5) and indexers (6) for measuring work progress, and production status information can be generated from these sensors (4, 5, 6, 9, 31, 33).

5. The production machine (1, 28) as claimed in one of the preceding claims, characterized in that signals can be picked up from the machine control of the production machine (1, 28), in particular signal lamps (7, 35) of the production machine (1, 28), and production status information can be generated from the machine control, in particular from the signal lamps (7, 35).

6. The use of a keypad or switch array (25, 34) or of a touch-sensitive screen (43) and/or of sensors (4, 6, 9, 31, 33) in particular of sensors (4, 9, 31, 33) for determining the filling status of buffer zones (3, 8, 30, 32), of sensors for measuring pressure (5) and of indexers (6) for measuring work progress, and/or a machine control of the production machine (1, 28), in particular of signal lamps (7, 35), for generating events in the case of a method for operating a production machine (1, 28), in which production information, in particular with respect to the capacity utilization and/or with respect to the reliability and/or with respect to the availability of the production machine (1, 28), is generated, the method having the following steps:

setting up an evaluation status model (47) with a number of evaluation statuses, with precisely one time account corresponding to each evaluation status,

setting up an interpretation status model (48, 54), transitions between statuses (49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62) of the interpretation status model (48, 54) being established in accordance with events which can be picked up on the production machine (1, 28),

assigning statuses (49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62) of the interpretation status model (48, 54) to statuses of the evaluation status model (47),

the time account of the evaluation status applicable at a particular time being increased during the operation of the production machine (1, 28) by an amount which corresponds to the time period in which the production machine (1, 28) is in the evaluation status concerned, the signals generated by an operator with the aid of the keypad or switch array (25, 34) or with the aid of the touch-sensitive screen (43) and/or the signals picked up by sensors (4, 6, 9, 31, 33) and/or the signals picked up by the machine control being used for generating events.

7. The use of a keypad or switch array (25, 34) or of a touch-sensitive screen (43) in a method for operating a production machine (1, 28) as claimed in claim 6,

8. The use of sensors (4, 6, 9, 31, 33), in particular of sensors (4, 9, 31, 33) for determining the filling status of buffer zones (3, 8, 30, 32), of sensors for measuring pressure (5) and of indexers (6) for measuring work progress, for generating events in the case of a method for operating a production machine (1, 28) as claimed in claim 6 or 7,

in which, when setting up the interpretation status model (48, 54), transitions between statuses (49, 50, 51, 52, 53, 55, 56, 57, 58, 59, 60, 61, 62) of the interpretation status model (48, 54) are established in accordance with signals of sensors (4, 6, 9, 31, 33), in particular of sensors (4, 6, 31, 33) for determining the filling status of buffer zones (3, 8, 30, 32), of sensors for measuring pressure (5) and of indexers (6) for measuring work progress, it being possible for the signals to assume discrete statuses which can be described by a status model (45) and used as events of the interpretation status model (48, 54).
