An apparatus for surface treatment of articles comprises a plurality of trays (4) each carrying one or more piece-holding spindles (3). A primary transport assembly (19) removably engages the trays (4) to transfer them according to a step-by-step motion between a plurality of stopping locations (A . . . J) distributed along the movement path (P), along which respective work stations (12, 13, 14, 15) operate. At least one additional transport assembly (31a, 31b) withdraws each tray (4) from the primary transport assembly (19) at one of said stopping locations (A . . . J), for moving it at one of said work stations (12, 13, 14, 15), and engaging it again with the primary transport assembly (19).

A treatment plant and method for treating workpieces, in particular for coating and/or drying vehicle bodies, having a treatment device with a housing in which a treatment space is accommodated. A conveyor system having a multitude of transport trolleys for conveying workpieces through the treatment space, wherein each transport trolley has a chassis and a fastening device for at least one workpiece, which are coupled together by means of a connecting device. Outside the treatment space, there is a guiding area with a travel space for the chassis. The travel space is connected to the treatment space via a connecting passage such that the chassis of a transport trolley can move in the travel space and at the same time the fastening device is entrained in the treatment space and the connecting device extends through the connecting passage. The travel space is defined by a travel space housing and a gas device is present to feed a throughflow gas, in particular air, to the travel space. At least a major part of the throughflow gas can again be discharged from the travel space as exhaust gas, without this throughflow gas reaching the treatment space through the connecting passage.

Apparatus for painting mainly flat products including a spray booth, in its turn including a plenum, a conveying belt for conveying products at least a device for applying paint, and at least one suction plant, wherein the plenum of the spray booth has a symmetric M-shape including, from the respective peripheries to the centre of the plenum: two first descending surface portions tilted towards the periphery; two second lateral surface portions parallel to the belt; two third descending surface portions, with a tilt towards the centre, opposite the tilt of the first portions; a fourth central surface portion parallel to said belt, the fourth central surface portion being closer to the conveying belt than the lateral parallel sections.

A coat body with satisfactory properties is manufactured. A coat body 5 is manufactured by a step (a) of forming a first coat liquid layer 3a by applying a first coat liquid onto a first surface of a base member 1 loaded out from a carry-out unit, a step (b) after the step (a), of forming a second coat liquid layer 4a by applying a second coat liquid onto the first coat liquid layer, a step (c) after the step (b), of forming a coat layer 3a and a coat layer 4b by drying the first coat liquid layer and the second coat liquid layer, and a step (d) of loading in the base member including the coat layer 3b and the coat layer 4b formed thereon by a carry-in unit. And, in the step (a), the first coat liquid is applied onto the first surface of the base member. In the step (b), the second coat liquid is atomized onto the first surface of the base member.

A production line of a CA abrasive, including: a belt mold, the belt mold being provided with a cavity; a transmission device, configured to drive the belt mold to run; a slurry coating mechanism, configured to coat a slurry on a surface and into the cavity of the belt mold; a slurry scraping mechanism, configured to scrap the slurry coated on the surface of the belt mold into the cavity; a drying mechanism, configured to dry the belt mold so that the slurry is dried and precipitated into abrasive grains; a separation mechanism, arranged below the drying mechanism and configured to shake down the abrasive grains in the cavity of the belt mold by vibrating; a sweeping mechanism, configured to sweep slurry fragments of the belt mold after separation; and a release agent coating mechanism, configured to spray a release agent to the swept belt mold.

An arrangement is disclosed for the preferably automatic coating of objects with a coating material, in particular coating powder. The arrangement includes at least one spray device having a spray nozzle via which the coating material is dispensable in a main spraying direction. An extension is further provided, wherein an end region of the extension facing the spray device is preferably detachably connected to an end region of the spray device associated with the extension opposite from the spray nozzle. The arrangement further includes a preferably horizontally extending guide via which the extension with the spray device connected thereto can be longitudinally moved in the direction of extension of the guide relative to the object to be coated. The main spraying direction of the spray nozzle may be implemented so as to deviate from the direction of extension of the guide by a predefined or definable angle.

The disclosure relates to an operating method for a coating system, in particular for a painting system, for coating components (2), in particular motor vehicle body components (2), having the following steps: conveying, by means of a conveying device (3), the components (2) to be coated in a conveying direction through a coating booth (1), coating the components (2) in the coating booth (1) with a coating product by means of an application device (17-19) which applies a spray jet of the coating product, a portion of the applied coating product being deposited on the components (2) to be coated while another portion of the applied coating product floats into the interior of the coating booth (1) as an excess coating product mist (21), and reducing the excess coating product mist (21) from the interior of the booth by means in addition to or other than the downwardly directed air flow generated by a filter ceiling. In addition, the disclosure includes a correspondingly designed coating system.

A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. Additionally, the robot enables routine cleaning and maintenance to be performed without personnel entering the spray booth and without stopping the vehicle conveyor, due to simplified outer arm design, improved home positioning and an airlock booth adjacent to the robot pedestal. Service personnel can clean and service the applicator and other components on the outer arm from the airlock booth, while other robots continue painting parts moving on the conveyor, without allowing fume-laden vapors into the operator aisle.

A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. This is accomplished by an arrangement of shut off valves and pumps, including a pump for paint and a high-efficiency pump for low viscosity solvent, operating in a sequence to push paint through a minimal-length supply line to the applicator, using almost all of this paint for painting the part, before returning to a cleaning stand and expelling the remaining paint and solvent in the supply line.

The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. The robot also features kinematics providing redundant inner arm rotation. The arm kinematics, along with the smaller arms, a paint supply line routed through the center of first and third arm joints, and optimized motor conductor routing, dramatically improve near reach flexibility. The improved near reach flexibility in turn allows a smaller spray booth than possible with previous robot architectures.
