Abstract: A method for operating a surface treatment plant, resulting overspray in a coating booth is taken up by an air flow. The air flow loaded with overspray is conveyed as exhaust air flow to at least one separation unit in which overspray is separated out. In a supply region upstream of the at least one separation unit and/or in an internal space of the at least one separation unit, a filter aid having a separation aggregate state is added to the exhaust air flow and forms, with the overspray, a separation mixture which is separated in or at the at least one separation unit. The filter aid used is solid or liquid in the separation aggregate state. In the at least one separation unit, conditions are established in which the filter aid transitions from the separation aggregate state into a gaseous aggregate state such that the gaseous filter air can separate from the separation mixture.

Abstract: In a method for operating a surface treatment installation, overspray produced in a coating booth is taken up by an air stream and carried to one or more one-way filter modules, in which overspray is separated. Once a limit loading with overspray is reached, a one-way filter module is exchanged for an empty one-way filter module. Depending on the nature and characteristics of the overspray, the one or more one-way filter module(s) may be chosen from a set of different one-way filter modules. A set of filter modules for use in a surface treatment installation is provided having various filter modules formed as exchangeable one-way structural units with a module housing and a filter unit. The module housings of the various filter modules have the same-connection module inlets and the same-connection module outlets and at least the filter units of two different filter modules are formed differently.

Abstract: A separator unit having a panel-shaped separator electrode on which at least one separator surface is formed for the overspray. A feed device ensures that a separator liquid can be fed to the separator surface of the separator electrode. It has a channel that can be filled with the separator liquid, and a removal device which can remove separator liquid from the channel. The latter includes a shape-changing, flexible and/or elastic expansion element arranged in the channel, which at least partially delimits a closed cavity. The removal device includes a pump device with which a pressure medium can be pushed into the closed cavity. As a result of the volume expansion of the closed cavity when “pumping up” said expansion element, separator liquid is displaced over the edges of the channel and from here it can be conducted onto the separator surface of the separator electrode in a suitable manner.

Abstract: A method for precipitating overspray from the overspray-laden booth exhaust air of coating installations, in particular from painting installations, the overspray is carried by an air stream to a precipitation device, where a majority at least of the solid material is precipitated from the overspray. The overspray-laden booth exhaust air is guided through filter modules, in which overspray is precipitated and which are designed as replaceable one-way components having a filter housing and a filter unit, wherein each filter module is replaced by an empty filter module after reaching a loading overspray. Moreover, the invention relates to a device for precipitating overspray by means of such one-way filter modules, and to an installation for coating objects, in particular vehicle bodies.

Abstract: The invention relates to a method for operating a surface treatment system in which overspray, which is generated in one or several coating booths, is picked up by an air stream and is guided to one or more one-way separation units in which the overspray is separated, said units being respectively exchanged, after reaching an overspray charge limit, as charged one-way separation units with an empty one-way separation unit. Said charged one way separation units are used to produce a treatment material which enables a later valuation.

Abstract: The invention relates to a device for separating overspray from the booth air of coating booths, in particular painting systems, charged with overspray. The device includes a separation unit through which booth air charged with overspray can be guided and in which overspray is separated. The separating unit is designed as an exchangeable structural unit having a filter housing, an inlet opening and a filter unit. The air flow charged with overspray can be guided via the air guiding device to the separation unit. The separating unit includes an inlet collar which defines the inlet at least in sections and the air guiding device includes a connecting sleeve, which immerses in such a manner into the inlet opening when the separating device is in operation in such a manner that said connecting sleeve is surrounded by the inlet collar of the separation unit.

Also stored is the course of a second boundary surface or boundary line, which runs at a distance from the first boundary surface or boundary line. Finally, the course of a contour which represents the course of the object fixed to the holding frame is also stored.

Abstract: A device with which electrical energy can be transferred from a power cable running along a stationary rail of a transport system to a moving element that can be driven along the rail. Each moving element has for this purpose a transfer head which works inductively together with the power cable. The power cable is attached with the aid of carrier profile which extends substantially along the entire length of the rail and is fixed in a releasable manner to the rail, which element has at least one a trough-like holder open to the side in which the power cable is laid. The power cable is thus relatively easily and accurately laid, avoiding hanging loops of cable which could be damaged by abrasion by the passing transfer heads of the moving elements.
