A device is provided for detaching a finish-molded workpiece, made of a thermoset, from a compression molding tool and for removing the workpiece from the molding press. In order to be able to carefully detach and remove compression molded parts of any desired shape from the compression molding tool, the removing gripper, which is preferably manipulated by an industrial robot, is designed according to the invention as a dimensionally stable suction bell which is adapted to the workpiece, covers the entire workpiece in a true-to-shape manner up to the workpiece edge and, with a contact-side soft-material seating, can be brought to bear in a sealing manner against the workpiece. Pockets which are sealed off from one another and each of which can be subjected individually to a vacuum are incorporated in the soft-material seating. Each of the separate vacuum connections mutually free of reaction is provided with a monitoring device which emits a signal in the event of a drop in vacuum below a threshold value. A plurality of plungers which can be set down on opposing surfaces on the lower die are attached to the edge of the suction bell. The removing gripper can be pushed off the lower die by the plungers.

A method and a device for the automated application of a self-adhesive paint film to a three-dimensionally curved bodywork part, using a robotic application tool, the paint film being held ready in the form of a multi-layered film composite ready for picking up. After picking up has taken place, a protective strip on the adhesive side is removed from the film section, which is held taut, by means of a contact piece attached to the film composite on the end side and the adhesive side of the film section is thereby exposed. The paint film section is subsequently aligned above the body part to be covered, at a small distance from it, and is progressively pressed onto the bodywork part from the spaced-apart, taut position by means of a roller or doctor moving over the paint film. In order to be able to apply even large or curved paint film sections without creases and at justifiable tool costs, use is made of a rectangular film composite which protrudes on all sides over the bodywork portion to be covered and is secured on all four sides in a rectangular suction frame. As a result, during the application of the paint film, the latter is held under tensile stress in the longitudinal direction and in the transverse direction. To simplify the tool, the protective strip on the adhesive side is removed from the paint film in a stationary manner.

A method and a device for the automated handling of resin-impregnated mats of differing shape and size during the production of SMC components, utilizes a suction gripper which can be manipulated multiaxially. A plurality of suction bells are distributed in a grid pattern on the suction gripper, each suction bell being actuable individually by a vacuum. The rigid suction bells, which are mounted via a flexible element, have a cup-shaped cross section with an edge that tapers to a point, and can be placed onto and form a seal with the resin-impregnated mats. Rotating brushes are provided for cleaning the suction bells. The suction gripper is combined with pivotable fixing spikes for securing the stack of mats at the uppermost layer of the stack. The suction bells can be raised and lowered to different levels via lifting cylinders and can be fixed in any desired intermediate positions by means of brakes.

A method for the automated, series application of a self-adhering protective film to a surface portion of vehicle body includes (1) readying of a film piece, pulled off from a supply roll, in a readying station in a stretched-out, fold-free state by at least one holding element; and (2) pulled off the film piece to the desired length from the supply roll, cutting off the film piece and holding on opposite edges, with the fold-free stretched-out state being retained and being transferred into the application station. The next film piece, which is pulled behind by the film piece is held stretched out in the fold-free state by the at least one holding element of the readying station. The film piece is applied to the body by lowering it in a positionally correct manner, by the at least one application robot, onto an associated surface portion of the body and is pressed onto the portion in a fold-free and bubble-free manner.

A method for manufacturing SMC components from an appropriately adapted amount of a fibrous reactive synthetic resin which is provided in the form of defined blanks of prepregs. The prepregs are placed in a defined position into a heated mold of a molding press, the heated resin/fiber mass is flow-molded in the closing mold to form the SMC component, said component is thermally cured and subsequently removed from the mold. Two different approaches are taken, one being intended for introducing the resin mass into the mold as multiple layers and the other for introducing the resin mass as a single layer.

The invention relates to a method for cleaning at least one surface (12) of a component (10), using a cleaning device (14), wherein the surface (12) of the component is cleaned by a cleaning head (18) movable by a positioning device (16), said cleaning head (18) exerting a contact pressure on the component (10). The positioning device (16) has a rough positioning system (20) and a fine positioning system (22), wherein the cleaning head (18) is moved in a force controlled manner by the rine positioning system (22) in at least one direction of movement (24, 26, 28, 30, 32, 34). The invention also relates to a corresponding cleaning device for implementing the inventive method.

In an apparatus for the conveyance and positioning of a vehicle supported on its own wheels along a production line, the vehicle wheels of each vehicle side are assigned conveying systems, for example apron conveyors or drag-chain conveyors, by means of which the vehicles can be moved further on in strokes. So that the vehicles can be positioned and oriented accurately and efficiently in the longitudinal and transverse directions in an automation-compatible and type-flexible way, in each workstation, the two wheel tracks are assigned in each case a prismatic shaped wheel well which can accept variously sized wheels in the same position. The vehicle wheels are supported transversely displaceably therein. Furthermore, a wheel support is arranged at a distance from the wheel wells and can support the wheels of the other vehicle axle likewise so as to be transversely displaceable. The wheel supports cover the various center distances of all the vehicle types occurring in the production line. The same applies to the width of the rolling tracks, the wheel wells and the wheel supports. Each of the wheel wells and the wheel supports has a pair of movably guided centering edges which project above the rolling level of the rolling tracks and which can be laid against mirror-symmetrical sides of the vehicle tires and can be moved by means of a centering mechanism transversely to the conveying direction positively in synchronism and mirror-symmetrically to the center line of the production line.

A method and device for automated application of lacquer film, which is integrated into a film composite, to a bodywork part using a robot-guided application tool. An adhesive-side protective strip is removed in a tool integrated manner and the stretched film blank is applied to the bodywork part using a doctor above the application point in the presence of a visible protective strip in a tool integrated manner. In order to exclusively use two-layered film composites and therefore simple application tools, the film composite which is individually and disposed on a hard substrate in a forcibly flat manner is received using an adhesive strip which is stored in a tool integrated manner on a roller and which can be subsequently rolled up after use inside the tool in question whereby it can be applied to the film composite by means of a doctor in a tool integrated manner. The transferred lacquer film blank is then applied to the bodywork part after the adhesive side has been uncovered. The adhesive strip is used as a protective strip. The adhesive strip is then removed from the applied lacquer film and can be re-used in a subsequent application process in the application tool. The active working section of the adhesive strip can be automatically renewed inside the tool after it has been used several times.
