Abstract: A method for loading blanks to a head of the stamping press line includes providing a stack of blanks at a pick-up position; loading blanks from the stack of blanks to the head of the stamping press line; before the stack of blanks is exhausted, creating a buffer by raising a predetermined number of blanks from the top of the stack to a position above the stack; and loading blanks from the buffer to the line while replacing the stack of blanks with a new stack of blanks. A handling system for creating a buffer includes one or more buffer robots with one or more supporting tools on which the blanks can be held, and one or more separating tools to separate one or more blanks at the top of the stack from the underlying blank of the stack.

Abstract: The system includes at least two industrial robots, each with a wrist and an auxiliary arm connected to the wrist by a respective first swivel joint, and a control unit for joint control of said robots; it further includes a crossbar connected at one end thereof to the auxiliary arm of one robot, and at another end thereof to the auxiliary arm of another robot, by a respective second swivel joint, the crossbar having at least two crossbar portions, each attached to the auxiliary arm of one robot and each arranged to carry a tool for picking workpieces, and the crossbar portions being linked to each other through a shifting arrangement such as to be displaceable one with respect to the other in their longitudinal direction.

Abstract: Included are a transfer unit for receiving blanks outputted from the blanking shear or press; at least one stacking support for stacking blanks thereon; one or more stacking robots to pick blanks from the transfer unit and place them on the stacking support, and at least one handling robot configured to position one or more centering pins for assisting the placement of the blanks on the stacking support.

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 system including at least two robots for handling parts and a robot control unit arranged for control of said at least two robots. Each of the robots is arranged with a parts handler device including a rigid arm with one end connected to the end element of an arm of the robot by a first swivel arranged for radial movement of the rigid arm in relation to the end element. Each of the robots is also arranged with a gripper connected to the rigid arm by a second swivel arranged for free, passive rotation of the gripper in relation to the rigid arm. The method includes generating instructions for the at least two robots to pick and/or move and/or place a part and sending the instructions to each robot simultaneously.

Abstract: A system and method for production of manufactured parts including a production process having at least one industrial robot equipped with a handling tool for picking up the manufactured part. The robot is arranged in a quality inspection cell and the robot is programmed to hold the manufactured part in at least one known position in the quality inspection cell and present the part for a quality inspection. The quality inspection may be made visually by an operator or with the aid of a tool or sensor or by means of automatic sensors. In other aspects of the invention a method, system and a computer program for carrying out the method are described.

Abstract: A device for handling a part. The device is configured for coupling to a handler. The device comprises a rigid arm, a support coupled to the rigid arm, a motor mounted on the arm, and a transmission coupled to the motor and the support. The rigid arm is configured to rotate integrally with an end element of the handler when the rigid arm is coupled to the handier. The support is turnable relative to the rigid arm, and the support is configured for coupling, to a gripping element. The motor is configured for actuating turning of the support relative to the rigid arm.
