Abstract:
A painting plant (10) comprises at least one painting booth (11) containing a painting system (12) intended to apply paint onto objects (13) placed in the booth advantageously by means of a conveyor (14). The plant comprises a magazine (19,119) which contains a plurality of cartridges (20) containing paint, and a system (23) for automatically transporting the cartridges from the magazine (19,119) to arrival stations (33) for supplying the paint from the cartridges (20) to the painting system (11) inside the booth.
Abstract:
A plant (10) for the treatment of bodywork comprises at least one trolley (11) designed to support a bodywork (12) to be heated and a conveyor line (13) for transporting the trolley along the plant. The trolley (11) comprises a rack extending longitudinally in relation to its direction of movement and along the plant there is at least one motorized toothed wheel (61) which is intended to engage in the rack (62) upon passage of trolley so as to provide the trolley with a forward thrust. A synchronization system (63, 64, 65) allows engagement of the toothed wheel (61) in the rack (62) while the trolley advances, avoiding jamming or stoppages. An additional traction method is also described.
Abstract:
A transport system for industrial plants comprises at least one trolley (10) for the autonomous transport of an object (25) and at least one skid (20) intended to support the object (25). The trolley (10) comprises an AGV-type motorized handling platform (11), a motorized lifting system (14) and a roller table (15) equipped with rollers (17, 18). The roller table (15) is supported on the motorized lifting system (14) so as to move on command between a raised position and a lowered position on the trolley, and the roller table (15) is intended to support a skid (20) resting on the rollers (17, 18) to be transported. At least one station (30) for loading/unloading the skid (20) from and onto the trolley may also be provided. At least one sequential conveyor may be provided at the start or at the end with a loading/unloading station (30).
Abstract:
A painting booth (10) comprises a painting chamber (11) inside which the paint is sprayed and which is crossed by an air flow for evacuation of the overspray from the booth. The air flow exiting the booth passes through an overspray removal unit (17) for removing the overspray from the air flow. The removal unit (17) comprises an incoherent mass of cleaning elements (25), possibly pellets, kept in a stirred condition, through which the air flow containing the overspray passes so as to release the overspray onto the elements of the mass. A method for removing the overspray and a plant with the booth (10) and a combustion unit (32) are also described.
Abstract:
A plant (10) for the treatment of bodyworks comprises a sequential transportation system (11) for bodyworks (14) for immersion of the bodyworks inside at least one treatment basin (12). At least one transducer (18) is associated with the basin (12) and is designed to detect vibrations on the walls of the basin (12) and emit a corresponding electrical signal. An electronic processing unit (19) is connected to the transducer (18) for receiving the said electrical signal and is designed to process the electrical signal received in order to detect in said electrical signal a pulse signal indicative of the impact of a bodywork against the bottom of the basin and emit consequently a fall signal (2) which may be used for example to stop the plant.
Abstract:
A plant (10) for the immersion treatment of vehicle bodies comprises at least one skid (11) intended to support a body (12) to be treated, at least one process liquid tank (15), a line (13) for conveying the skid above the tank and means for overturning and immersing, inside the tank, the body (12) on the skid (11) which has been positioned above the tank (15) by means of the conveyor line (13). The skid (11) comprises a base part (16) and a part (17), for supporting the body, which is rotatable on the base part (16) by means of a shaft (19) with axis (18). The skid (11) further comprises a toothed wheel (23) which is connected to the shaft (19) and, alongside the tank, there is provided at least one rotation actuating device (32) which comprises a rack (33) intended to engage the toothed wheel (23) so as to actuate rotation of the supporting part (17) of the skid by means of movement of the skid.
Abstract:
A method for the coating by electrodeposition of objects (11) such as vehicle bodies or parts thereof, in a sequential plant (10), comprises the steps of sequentially receiving each object in a treatment start zone (13), placing the object in a container (15) which can be sealingly closed, closing the container (15) and, by means of a sequential transport line (12), transporting the container (15) with the object closed inside it through a series of treatment stations (17, 20, 23) to a treatment end zone (14) where the object is extracted from the container (15). The treatment stations of the plant comprise in sequence an initial station (17) for the modification of the atmosphere in the container (15), one or more electrodeposition stations (20) and an end station (14) for restoring the atmosphere in the containers (15) to the external conditions. Each station comprises fluid and/or electrical connections (19, 22, 25) for connection with the inside of the container (15) through connection ports (16) on the container (15).
Abstract:
A system (10) for coating objects (11) with a coating agent, in particular for painting vehicle bodies or vehicle parts, comprises at least one coating head (13) with a plurality of nozzles (20) for applying the coating agent to the objects to be coated and a handling robot (12) which guides the coating head (13) along movement paths on the surface of the objects to be coated. At least some nozzles (20) of the plurality are supported in the head (13) so as to have emission ends (32) mutually movable by means of controlled actuators (26, 31) at least in one direction of emission of the coating agent.
