Abstract

A system and corresponding method are provided for controlling production in a blow room, the blow room including a controller, a supplying machine having a supplying part, and a machine to be supplied that has a filling level measurement. The supplying machine and the machine to be supplied are connected to the controller. A production area is defined for the supplying machine and includes a minimum production and a maximum production. Production of the supplying part of the supplying machine is determined based on a filling level of the filling level measurement. When production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the machine to be supplied.

First claim

The invention claimed is:

1. A method for controlling production in a blow room, the blow room including a controller, a supplying machine that dispenses fiber material to a conveyor via a supplying part associated with the supplying machine; and a receiving machine supplied with the fiber material from the conveyor, the receiving machine having a filling level measurement, wherein the supplying machine and the receiving machine are connected to the controller, the method comprising
defining a production area for the supplying machine having a minimum production and a maximum production for the supplying machine;
determining production of the supplying part of the supplying machine based on a filling level of the filling level measurement of the receiving machine; and
when production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the receiving machine.

2. The method according to claim 1 , wherein the production area includes one or more additional fiber processing machines operationally located between the supplying machine and the receiving machine.

3. The method according to claim 2 , further comprising adjusting operation of the one or more additional fiber processing machines when there is a change in the production of the production area.

4. The method according to claim 1 , wherein the production of the production area is determined by the receiving machine.

5. The method according to claim 4 , wherein the receiving machine is configured to turn on the supplying part of the supplying machine via the controller based on a low filling level at the receiving machine.

6. The method according to claim 1 , wherein when the production of the production area exceeds the maximum production, the controller alters production of the receiving machine or shuts down the receiving machine.

7. The method according to claim 1 , wherein the controller saves production values of the receiving machine, and saves and evaluates periods of time between shutdowns of the supplying machine, the controller determining an adjustment in the production of the production area in order to minimize the shutdowns.

8. A system or controlling production in a blow room, comprising:
a controller;
a supplying machine configured to dispense fiber material to a conveyor via a supplying part associated with the supplying machine, wherein a production area is defined for the supplying machine in the controller having a minimum production and a maximum production;
a receiving machine that is supplied with the fiber material from the conveyor, the receiving machine comprising a filling level measurement;
the supplying machine and the receiving machine in operative communication with the controller; and
the controller configured to operate the supplying machine and the receiving machine such that
production of the supplying part of the supplying machine is determined based on a filling level of the filling level measurement of the receiving machine; and
when production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the receiving machine.

9. The system according to claim 8 , further comprising one or more additional fiber processing machines operationally located in the production area and in operational communication with the controller.

10. The system according to claim 9 , wherein the controller is configured to adjust operation of the one or more additional fiber processing machines when there is a change in the production of the production area.

11. The system according to claim 9 , wherein the controller stores various settings of the additional fiber processing machines corresponding to different productions of the production area.
