Claims14
A method for controlling a motion of a conveyor system of a servo press installation including at least a first servo press and a second servo press which are operated at an optimum offset in accordance with a criterion, the conveyor system comprising at least one conveyor apparatus for movement of a product which is to be processed by the servo press installation, and motion of the at least one conveyor apparatus being controlled by a motion controller of the conveyor system in accordance with the optimum offset, the method comprising:
- determining a motion curve of the conveyor system including a first margin when the conveyor system is within a workspace of the first servo press, a second margin when the conveyor system is within a workspace of the second servo press, and a segment between the first and second margins which is entirely outside respective pressing workspaces of the at least one first servo press and the second servo press;
- defining a time interval for motion within said segment based on the criterion;
- adjusting the motion curve for motion of the product within the segment such that the motion curve in the first and second margins is unchanged, with reference to the defined time interval;
- and
- controlling the conveyor system in accordance with the adjusted motion curve.
A motion controller for controlling a motion of a conveyor system of a servo press installation comprising at least a first servo press and a second servo press which are operated at an optimum offset in accordance with a criterion, the conveyor system comprising at least one conveyor apparatus for movement of a product which is to be processed by the servo press installation, the motion controller comprising:
- a storage unit for storing data on a motion curve of the conveyor system including a first margin when the conveyor system is within a workspace of the first servo press, a second margin when the conveyor system is within a workspace of the second servo press, and a segment between the first and second margins which is entirely outside respective pressing workspaces of the at least one first servo press and the second servo press;
- a delivery unit for delivering an instruction with respect to a time interval for motion within the segment based on the criterion;
- and
- a calculation unit for calculating an adjusted motion curve for motion of the product within the segment such that the motion curve in the first and second margins is unchanged, with reference to the defined time interval;
- wherein the motion controller controls the conveyor system in accordance with the adjusted motion curve.
A non-transitory computer-readable medium encoded with a computer program which, when executed by a processor of program-controlled device, causes control of a motion of a conveyor system of a servo press installation including at least a first servo press and a second servo press which are operated at an optimum offset in accordance with a criterion, the conveyor system comprising at least one conveyor apparatus for movement of a product which is to be processed by the servo press installation, and motion of the at least one conveyor apparatus being controlled by a motion controller of the conveyor system in accordance with the optimum offset, the computer program comprising:
- program code for determining a motion curve of the conveyor system including a first margin when the conveyor system is within a workspace of the first servo press, a second margin when the conveyor system is within a workspace of the second servo press, and a segment between the first and second margins which is entirely outside respective pressing workspaces of the at least one first servo press and the second servo press;
- program code for defining a time interval for motion within said segment based on the criterion;
- program code for adjusting the motion curve for motion of the product within the segment such that the motion curve in the first and second margins is unchanged, with reference to the defined time interval;
- and
- program code for controlling the conveyor system in accordance with the adjusted motion curve.
