Abstract: It comprises a transfer unit for receiving the blanks; at least one stacking support for stacking blanks thereon; at least two industrial robots, said robots being arranged with respect to the transfer unit such that they are operable in at least an individual operating mode in which each robot picks a blank from the transfer unit in order to place it on a stacking support, and a joint operating mode in which a group of said robots act simultaneously on one and the same blank, to pick it from the transfer unit in order to place it on a stacking support; and robot control means adapted to operate the industrial robots in individual operating mode or in joint operating mode, depending on a parameter related to the size of the blanks, the weight of the blanks, the output rate from the blanking shear or press, and/or a combination thereof.

Abstract: A method for operating a mechanical press including an electric drive motor, a drive control for controlling the motor, a ram, a flywheel, a clutch and a member for translating rotational motion of the flywheel in a first rotation direction into a linear motion of the ram arranged to be lowered and raised along a linear path for operating the press to carry out a press production cycle. The press cycle includes a pressing part and one or more non-pressing parts. The press includes a second drive motor or actuator arranged connected to the ram and by providing a control output to the drive control, the speed of the second drive motor is made variable during at least one part of the press production cycle. The press may be reversed between production cycles. A press and system including such a press.

Abstract: An press line including at least one mechanical press with at least one electric drive motor, a ram, a mechanical unit for operating the press, and one other device or auxiliary production device. The press is arranged so that the speed of the at least one said drive motor may be varied during at least one pressing or non-pressing part of a press cycle. Improved operating characteristics and optimised energy use and cycle times are obtained by controlling the speed of the motor and synchronizing a movement of the press to a movement or position of at least other device, loader or other press. A system includes the press. A computer program controlls the press line.

Abstract: A method for operating a mechanical press including at least one electric drive motor, a drive control for controlling the at least one motor, a ram, a mechanical element for translating rotational motion of the at least one motor to linear motion of the ram in a first rotation direction, into a linear motion of the ram arranged to be lowered and raised along a linear path for operating the press to carry out a press cycle including a pressing part and one or more non-pressing parts of the press cycle, and by providing a control output to the drive control such that the speed of the at least one drive motor is varied during at least one pressing or non-pressing part of the press cycle. The press may be reversed between production cycles. Also press and system including a such press.
