Abstract:
An adjustable control valve for flow regulation of gas or liquid has a controlled hose clamp device, preferably with two clamping members (K1, K2) disposed on respective sides of a hose (A) for adjustable compression of the hose and thereby setting of the flow cross-section of the hose at a compression site between the clamping members. The control valve comprises further a movable cam disk, e.g. a rotatable eccentric sheave (E), actuated by a shifting mechanism, preferably a step motor, disposed for variable compression of the hose in accordance with the position of the cam disk or eccentric sheave. For automatically controlled setting of the flow cross-section of the hose, the shifting mechanism may be arranged to be controlled from measuring means mounted for gauging the flow in the hose (A) downstream of the compression site (As). In practice such regulation may be used for controlling the quantity ratios between the supplies of paint, jet formation air and atomizing air, respectively, to an atomizing gun (P), preferably by means of a common data processing unit (D) inserted between the control valve (Sa, Sp, Sf) and measuring means (Ma, Mp, Mf) in all control loops (Qa, Qp, Qf) for the supplies of paint, jet formation air and atomizing air, respectively, to the spray gun (P).
Abstract:
A method and a mobile servo-operated robot system (VH, RA, LB, PL) for repair painting of motorcars utilize an associated computer system (LD) for the guiding of painting tools in accordance with preprogrammed operational data which are stored in one or more data bases. Topical data (AD) describing the repair painting to be performed, e.g. type of car, year model, colour code and painting area, are supplied to the associated computer system (LD), which then is actuated to search for corresponding operational data in its own data base (DB1) and/or possibly other, remotely connected data bases (DB2). The preprogrammed operational data provided in this way are then selected for the required control of the robot system (VH, RA, LB, PL) when performing the intended painting operation. The computer system (LD) is suitably connected to means (DR) for modifying program editing of the selected operational data in accordance with special prevailing conditions. A graphic screen for displaying the painting area together with the painting program may be used for this purpose.
Abstract:
A robot installation for painting objects inside a cabin (CA) having walls (WA, WB) isolating the object (AU) to be painted from the surroundings, is suitably integrated in the cabin walls in order to save interior cabin space and achieve a robot operation better adapted to the painting process. The installation comprises at least one main robot shaft (RS) associated with a painting tool and protruding through at least one slot (LS) penetrating the cabin walls for servo-controlled movements along such slots and possibly also in the direction of and/or about the axis of said shaft. Servo-drive means are disposed for controlling said robot shaft movements in accordance with a preprogrammed motional pattern for said painting tool, including tracking of a travelling object to be painted. Said slot is disposed on a rotatable element (CD, SC) suppported in or on the cabin walls, and the servo-drive means comprise means for controlling the rotational movements of the rotatable element in accordance with said preprogrammed motional pattern. The rotatable element may be a circular disc (CD) disposed for rotational movements in a plane identical or parallel withthe plane of a cabin wall (WA), the slot (LS) extending preferably along a diameter of said disc. Alternatively said rotatable element may be a hollow cylinder (SC) disposed for rotational movements about a vertical axis in or parallel with one of the cabin walls, said robot shaft protruding through at least one slot (LS) substantially parallel with said rotational axis. In practice the robot shaft is normally connected with the painting tool through manipulator link means (ML) having at least one and preferably three or more axes of motion.
Abstract:
A paint dosage device is particularly adapted to be mounted in close proximity to a spray gun (P) in a program controlled spray painting installation for dosed paint supply to the spray gun. The device comprises at least two dosage cylinders (SA, SB), each having a regulating piston (PA, PB) connected to regulation means (RA, MA; RB, MB) for setting the paint filling amount of the associated cylinder by controlled adjustment of the departure position of the regulating piston in the cylinder. The regulation means is also adapted for setting the dosage rate of the cylinder when supplying paint to the spray gun, by program controlling the displacement velocity of the regulating piston in the cylinder. A valve assembly (V1, V2, V3, V4) is arranged for connecting the cylinders (SA, SB) alternately to the spray gun (P) and putting the cylinder disconnected from the gun in connection with means for cleansing and paint filling. This paint dosage device is particularly suitable for application in the case the spray gun is provided with high tension electrode (E) for electrostatically charged atomizing of supplied electrically conductive paint. Each regulating piston (PA, PB) of the cylinders is then connected with the regulation means by means of an electrically insulating motion-transferring connection (IA, IB) and each valve (V1, V2, V3, V4) of the valve assembly is made electrically insulating.

Abstract:
Un procédé et un système robotique mobile servocommandé (VH, RA, LB, PL), qui servent à effectuer des retouches de peinture sur des voitures automobiles utilisent un système d'ordinateur associé (LD) destiné au guidage des outils de peinture en fonction de données opérationnelles préprogrammées qui sont mémorisées dans une ou plusieurs bases de données. Des données topiques (AD), décrivant la retouche de peinture à effectuer et relatives par exemple au type de voiture, à l'année modèle, au code de couleur et à la zone à peindre sont fournies au système d'ordinateur associé (LD), lequel est ensuite activé pour pouvoir rechercher les données opérationnelles correspondantes dans sa propre base de données (DB1) et/ou éventuellement dans d'autres bases de données connectées à distance (DB2). Les données opérationnelles préprogrammées ainsi fournies sont ensuite sélectionnées pour permettre la commande requise du système de robot (VH, RA, LB, PL) lors de la réalisation de l'opération de peinture désirée. Le système d'ordinateur (LD) est connecté de façon appropriée à un organe (DR) qui sert à modifier le programme éditeur des données opérationnelles sélectionnées, en fonction des conditions en vigueur particulières. Un écran graphique servant à afficher la zone à peindre conjointement avec le programme de peiture peut être utilisé à cet effet.
