A process and a production installation for producing shell-shaped, fiber-reinforced plastic parts are provided. The plastic parts can be produced efficiently, in an automated manner which is flexible with respect to the process and workpiece and is operationally reliable. A blank of the endless fiber mat corresponding to a workpiece is placed in an automated manner by industrial robots onto a clamping frame surrounding the female mold and is taken over by the clamping frame in a clamping manner and in such a way that it can slide after itself against a defined resistance. Wide-ranging accessibility required for this is created by a horizontally movable unit, comprising a female mold and a clamping frame, being temporarily moved completely out from the forming press and moved back again into the forming press after completion of loading.

A method and an apparatus for automated application of paint film to bodywork parts (1) and to a paint film composite (5) which is suitable for automation. A paint film composite (5) which is suitable for automation is created and adhesively bonded onto the bodywork part (1) in an accurate position and without any bubbles or creases by means of a robot-controlled application tool that is appropriate for this purpose. To securely hold the film composite (5), which has been picked up from a substrate, the suction grippers (30, 31) which grip the ends are angled in mirror-image form, in order in this way to prevent the ends from becoming detached from the suction grippers. The lower protective strip (9) is then at least partially pulled off, thus exposing the adhesive face of the useful part (6) of the paint film. The film composite (5) is aligned in the correct orientation at a short distance from the bodywork part (1) and the useful part (6) of the paint film is wiped onto the bodywork surface (1).

A method and apparatus for cutting through protective film in the region of covered-over joints and beads of vehicle bodies includes a freely programmable industrial robot having at least five degrees of motional freedom. An operating arm of the robot has a cutting and pressing tool which includes a knife having a blade for cutting through the protective film in the region of covered-over joints and beads, and the pressing tool comprises a rotary brush or air nozzle for pressing down the cut edges. In another embodiment, an air nozzle which emits a diffuse hot-air current is provided for cutting through the protective film.

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.

Taping down tool and method for the automated, series application of adhesive tape, in particular on surface parts of vehicle bodies. The taping down tool comprises a mount for an adhesive-tape roll containing adhesive tape to be applied, an application roller for the application of adhesive tape, which has been pulled off from the adhesive-tape roll, and a holding device, which is arranged upstream of the application roller, for holding ready adhesive tape, which has been pulled off from the adhesive-tape roll, between two application processes, the holding device moreover serving for the pressing-on of held-ready adhesive tape on the surface to be covered, so as to initiate an application process, and, after a forwards movement of the taping down tool, adhesive tape, which has been pressed on by the holding device, being taken over by the application roller which can be extended essentially perpendicular with respect to the plane of the pressed-on adhesive tape in the direction of the adhesive tape and is used for the force-controlled pressing-on of the adhesive tape.

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.

摘要:
An automatic application system for self-adhesive protective film to vehicle bodies is disclosed. Two separate application stations are provided, of which one application station contains two pairs and the other contains one pair of stationary industrial robots arranged opposite each other for the joint handling and application of one piece of film in each case. As a result, it is possible to stick all the body parts simultaneously within the cycle time. In each case, one robot of a pair of robots contains in its application tool the holder for a supply roll and a cutting device, whereas the opposite application robot of this pair of robots carries a suction strip. For the accurate-contour perforation of a stretched-out piece of film, the latter is moved along a stationary perforating tool. Arranged close to the robot is a magazine for a plurality of supply rolls, from which the application robot automatically picks up a supply roll as required. The supply rolls are relatively small and can contain the film needed for about 100 to 200 application procedures. Each supply roll can be provided with a disposable core made of hard paperboard or plastic.

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.
