  • Patent number: 8276508
    Abstract: An overload protector has an input element, an output element juxtaposed with the input element, and a clamping plate. Fasteners fix the clamping plate to one of the elements against relative movement. A coupling between the clamping plate and the other of the elements permits only limited relative movement of the elements through a stroke having a predetermined length in a predetermined direction. A connector between the clamping plate and the other element fixes the clamping plate and the other element together against relative movement until an overload force greater than a predetermined critical limit is exerted shifting either of the elements toward or away from the other element in the predetermined direction.

  • Patent number: 7690883
    Abstract: A device for stacking articles which are molded and stamped in a multi-impression molding and stamping tool includes a transfer device having a single gripper plate made of lightweight construction for accepting all articles ejected from one work cycle of the molding and stamping tool. A stacking station having two stacking baskets arranged on respective arms is arranged so that the baskets are pivotable about a first axis for moving a first basket of the two baskets to a transfer position and a second basket of the two baskets to an ejection position, the transfer device transferring the articles to the transfer position of the stacking station. An ejector unit and conveyor belt are arranged proximate the ejection position, each of the first and second baskets being pivotable about a second axis, perpendicular to the first axis, at the ejection position to a pivoted position.

  • Publication number: 20100024668
    Abstract: In order to further develop overload protection devices for machine tools, the invention relates to an overload protection comprising a force input element and a force output element which are rigidly and non-positively interconnected by means of a positive connection and can be moved relative to one another when an overload protection is actuated. The overload protection devices are characterized by an emergency running gear; by means of which the force input element and the force output element are interconnected so as to be guided towards each other in a controlled manner when the overload protection is actuated.

  • Patent number: 7361008
    Abstract: In the case of a thermoforming system, it is provided, for the purpose of changing over the moulds (11, 12) in a station (1) of this system, that one (4) of the two transporting devices (3, 4), for transporting the sheet (7) from one station to the other, can be displaced in the direction of the other transporting device (3), transversely to the conveying direction, in order to create space on one side of the lifting tables (9, 10) so that it is possible for the mould block (11, 12) to be moved out of the station onto a mould-changing arm (13) and, from there, onto a mould-changing carriage (15).
