APPARATUS AND METHOD FOR CONTROLLING ROBOT ARM
In an apparatus for controlling a robot arm with an end effector for packing workpieces in a box-shaped open container with a bottom wall and at least one side wall, an inner surface of the at least one side wall being covered with a contact prevention sheet having an indefinite shape, a controller determines whether a packing position of a selected workpiece in the box-shaped open container is adjacent to the inner surface of the at least one side wall of the container. The controller instructs the robot arm to move the selected workpiece picked up by the end effector downward while preventing the picked-up workpiece from entering a predetermined safety zone in response to determination that the specified packing position in the box-shaped open container is adjacent to the inner surface of the at least one side wall of the container.

Tooling for picking up two-dimensional workpieces
Tooling (100) for picking up two-dimensional workpieces comprises a main body (110) and a plurality of holding elements (131, 132) arranged on the main body (110), wherein the holding elements (131, 132) are movable relative to the main body (110) independently of one another. Each of the holding elements (131, 132) is fastened in an end region of an arm (121.1 . . . 10, 122.1 . . . 10). The arms (121, 122) are movable passively relative to the main body (110) along a linear movement path in a longitudinal extension of each particular arm (121, 122). The tooling (100) comprises, for each of the arms (121, 122) a fixing apparatus, by means of which a position of each particular arm (121, 122) along the movement path is fixable. On account of its passive character, the tooling (100) according to the invention is lightweight and can be produced cost-effectively. Compared with fixedly configured tooling, reduced costs arise on account of the configurability, because different types of tooling do not have to be kept available and provided. The storage area for replacement tooling is saved, and also an automatic tooling changing station or a manual tooling change become superfluous. As a result of the geometry according to the invention, the tooling (100) can be set easily, no complex movements and accordingly no complicated setting devices (for example multiaxial robots) are necessary.
IMPROVED STEERING OF GRIPPER HEAD OF A VACUUM GRIPPER OF A DIGITAL CUTTING SYSTEM
The invention relates to a computer-implemented method for a cutting system, the cutting system at least comprising a digital cutter and a gripper for picking up cut parts.
Therein, the digital cutter is built for cutting a part of a sheet according to a cut design, the cut part having a specific pathway of its boundary line.
The gripper is built for picking up the cut part from the sheet, wherein the gripper comprises a gripper head and a movement apparatus. Thus, the gripper head is provided with a plurality of degrees of freedom of motorized movement including a variable heading angle (Ψ) and/or variable lateral position (x- and y-position) in a plane parallel to the sheet. The gripper head comprises a plurality of suction spots having known geometric arrangement, said arrangement of suction spots defining a mean grid spacing.
According to the invention, the method comprises carrying out an optimization algorithm for determining a gripping pose in which the cut part is to be gripped by the gripper head. Therein, the optimization algorithm being programmed for maximizing a number of cut-part-facing suction spots coming to lie on the cut part in the gripping pose, wherein the optimization algorithm optimizes over heading angle candidates (Ψ) for the gripping pose within a range extending consistently over at least 90° and/or lateral position candidates for the gripping pose within sub-mean-grid-spacing range
under exploitation of first input data consistently representing the complete specific pathway of the boundary line of the cut part and second input data relating to the known geometric arrangement.
The determined gripping pose will be provided as output data.
ROBOTIC METHOD FOR LOADING CASES
The invention relates to a robotic method for loading cases on a packaging line from cases contained in a closed parallelepiped container and wherein it is proceeded with the loading of the packaging line, after opening of the container (Ca) by: /d/ insertion of a first jaw (30) of the clamp between the first face (F1) of the container and the first case (Et1) of the row of cases and, insertion of a second jaw (31) of the clamp between the last case (Etd) of the row of cases and the second face (F2) of the container, and approach of the jaws until seizing up the row of cases, /e/ piloting of the robotic arm so as to extract the row of cases from the container grasped by the motor-driven clamp (3) and load the packaging line (Lg) with the row of cases.
Unit for sorting moving parts
Unit for sorting parts moving along a conveyor belt comprising a transfer device (3) which comprises a roller (31) which is rotatably movable above the belt and a plurality of gripping tools (32) at the periphery of the roller which are each capable of selectively removing a part from the belt when the tools are brought into a removal position, each tool comprising a suction cup (321) attached to a tubular support sleeve (322) which is capable of creating a connection between the suction cup and an internal chamber (312) of the roller, said connection being kept at a negative pressure relative to the surrounding air, all of the suction cups which are brought into the removal position being depressurized, each sleeve being mounted so as to be translatably movable along the axis thereof through a wall (311) of the roller, an actuator (34) being designed to selectively control, in the removal position, the movement of the sleeve so that the suction cup engages with the part to be removed.
METHOD FOR CONTROLLING A GRIPPER
A gripper, which removes blanks from a web of material lying flat, includes gripping elements which can each be actuated separately. The gripping elements are mounted independently of one another in a frame so as to be displaceable perpendicularly to a reference plane parallel to the web of material. The gripping elements are set against the web of material and actuated in a takeover position of the gripper aligned with respect to the blank by means of a control device. In addition to the gripping elements located inside the contour line, there are also other gripping elements adjacent to the blank and located outside the contour line that are set against the material web as downholders. Gripping elements within the contour line of the blank are actuated and retracted from the material web, taking along the blank, before the gripper is lifted off the material web from the takeover position.
Bellows valve for vacuum systems
A valve for use within a vacuum cup of a vacuum gripping system is described. In one example, a vacuum cup includes a bellows and a valve assembly seated within an inner chamber of the bellows. The valve assembly includes a body disk seated within the inner chamber, a control disk seated toward a suction cup end of the bellows, a spring positioned between the body disk and the control disk, and a control stem extending through the central valve aperture of the body disk, through the spring, and secured to the control disk. When the control stem is seated within the central valve aperture, the valve assembly restricts fluid suction to within the inner chamber. When the valve control stem is unseated from the central valve aperture, the valve assembly conveys fluid suction to the suction cup end of the bellows.
