摘要:
A method for separating overspray from the cabin exhaust air of coating systems, in particular of painting systems, which is laden with overspray, the overspray is taken up by an air flow and conveyed to an electrostatically operating separating device. There, the bulk at least of the solids is separated from the overspray at at least one separating surface. An electrically conductive material or material mixture is used as a separating agent, which is applied to the at least one separating surface of the separating device and at the operating temperature of the separating device has a wax-like consistency. Also a separating device with such a wax-like material and a system for coating articles.

A device for separating paint overspray from the air of painting cubicles that is laden with overspray has in a housing at least one separating element, the surface of which is electrically conductive and is connected to one terminal of a high-voltage source. The separating element is assigned an electrode arrangement, which is connected to the other terminal of the high-voltage source. The air of the cubicle is made to flow past the separating element and the electrode arrangement in such a way that the overspray particles are colonized and deposited on the surface of the separating element. The separating element is moved continuously or intermittently, wherein a wiping device wipes off the overspray that is on the surface of the separating element. This can then be carried away by a suitable transporting device for disposal or re-use.

A set of roller conveyors is described, the members of which include a plurality of driven rollers disposed in two parallel tracks. Each member of the set has at least one electric feed-in block, which is connectable to the locally available system voltage and from this generates an output voltage, which is the same for all members of the set and is lower than or equal to the lowest system voltage, for which a member of the set is designed. The drive motors of the driven rollers are in this case designed for the output voltage of the feed-in block. In this way, the manufacturer of the roller conveyors may carry out the design, warehousing, and assembly of a roller conveyor independently of the different system voltages available from site to site and in this way may considerably reduce the costs associated therewith.

A roller conveyor system includes multiple carrier slides, which have runners, carry readable data memories and in particular are provided for transport of motor vehicle bodies. The roller conveyor system also has readers for reading out the data stored in the data memories, and a roller conveyor to convey the carrier slides. The roller conveyor comprises roller rails, which are arranged parallel to each other, and multiple rollers which are accommodated in the roller rails, and of which at least some can be driven independently of each other by drives, and of which at least some are provided with flanges. According to the invention, the data memories are accommodated in the runners, and the readers in the roller rails.

The invention relates to a method and a device for drying objects (2) in particular painted vehicle bodies. In said method, the objects (2) are displaced through a drying zone (6), in which they are cured in an inert atmosphere. The aim of the invention is to introduce the objects (2) into the drying zone (8), whilst at the same time preventing the entry of as much of the normal atmosphere of possible from the exterior. To achieve this, the objects (2) are conducted through a lock zone (7), which is located upstream of the drying zone (8) and in which the normal atmosphere lying outside the drying zone (8) and an inert gas atmosphere are present in strata as a result of a difference in densities. The objects (2) are displaced during their passage through the lock zone (7) from the normal atmosphere into the inert gas atmosphere by a motion comprising a vertical component.
摘要:
A roller conveyor including a plurality of driven rollers disposed in two parallel tracks. With each driven roller a separate drive motor is associated, which takes the form of a low voltage motor. The drive motors are supplied from at least one low voltage source. They are preferably hub motors, which are operated with direct current. By virtue of the low voltage technology, less expensive components may be used and the safety requirements may be reduced.

An apparatus for air treatment includes at least one reservoir which can be filled with a liquid, an air-conveying device and a device which ensures that for the treatment of the air to be treated the air comes into contact with at least a part of the liquid. A circulating device is provided, by which liquid in the reservoir is conveyed in a circuit out of the reservoir and back into the latter. For the purpose of sterilising the liquid, a device for mechanico-physical opening of cell membranes, for instance by electroporation or cavitation, is provided in the circuit. Such an apparatus can also be used for purifying exhaust air in a surface treatment installation.

A conveying device for conveying articles, in particular vehicle bodies, in a known manner comprises at least one skid, which comprises two parallel skid runners and a supporting structure, which connects the skid runners to one another, for the article to be conveyed. The skid runners are supported on two parallel tracks, which extend along a conveying path. As a driving device a linear drive is used, which comprises a plurality of energizable primary parts disposed in a stationary manner along the conveying path. Provided on each skid is a secondary part, which interacts with the actually adjacent primary part. The length of the secondary part in conveying direction is tuned to the distance between the primary parts such that at least one primary part is disposed in the immediate vicinity of the secondary part.

A system for painting objects, in particular vehicle bodies or add-on parts, comprising a spray booth in which a paint can be applied to the objects. A fluid flow, which receives overspray and possibly solvent arising during the painting process, passes through the spray booth from the top down. A recovery system for recovering the overspray and possibly the solvent comprises at least one substantially vertical pipe, through which the fluid led out of the spray booth and laden with overspray and possibly solvent can flow and the surface of which is provided with elevations and/or recesses in such a way that eddies form in the fluid flowing through the pipe and the paint overspray is deposited onto the circumferential wall and flows downward out of the pipe.
