Cleaning plant

Abstract

In order to produce a cleaning plant for cleaning work pieces which comprises at least one cleaning station in which the workpiece is subjected to a cleaning process in such a manner that the cleaning process can be organized in a flexible manner and easily adapted to changes in the workpiece, it is proposed that the cleaning plant should comprise at least one manipulating device which picks up a workpiece prior to treatment in a treatment area of the cleaning station, supplies the workpiece to the treatment process within the treatment area of the cleaning station and passes on the workpiece after the treatment in the treatment area of the cleaning station.

1 . A cleaning plant for cleaning workpieces comprising at least one cleaning station in which the workpieces are subjected to a cleaning process, and at least one manipulating device which picks up a workpiece prior to treatment in a treatment area of the cleaning station, supplies the workpiece to the treatment process in the treatment area of the cleaning station and passes on the workpiece after the treatment in the treatment area of the cleaning station,
 wherein the manipulating device exhibits at least three degrees of freedom of movement,   wherein the cleaning plant comprises at least one washing station which comprises a washing vessel in which the workpiece is located during a washing process, wherein the washing vessel has an access opening through which the manipulating device extends into the washing vessel during the washing process, and   wherein the cleaning plant comprises at least one cleaning station which comprises at least one spraying lance, wherein the workpiece is moved within the treatment area of the cleaning station by means of the manipulating device in such a way that a spraying opening of the spraying lance enters a cavity of the workpiece during the spraying process.   
     
     
         2 . A cleaning plant in accordance with  claim 1 , wherein the pattern of movement of the manipulating device is controllable in a manner specific to the type of work piece in dependence on the type of workpiece currently being handled. 
     
     
         3 . A cleaning plant in accordance with  claim 1 , wherein the manipulating device exhibits at least four degrees of freedom of movement. 
     
     
         4 . A cleaning plant in accordance with  claim 3 , wherein the manipulating device exhibits at least six degrees of freedom of movement. 
     
     
         5 . A cleaning plant in accordance with  claim 1 , wherein the manipulating device comprises a gripping device for grasping the workpiece. 
     
     
         6 . A cleaning plant in accordance with  claim 1 , wherein the manipulating device is in the form of a robot. 
     
     
         7 . A cleaning plant in accordance with  claim 1 , wherein the manipulating device is arranged in a static manner at a cleaning station. 
     
     
         8 . A cleaning plant in accordance with  claim 1 , wherein the access opening is arranged at the top of the washing vessel. 
     
     
         9 . A cleaning plant in accordance with  claim 1 , wherein the cleaning plant comprises at least one vacuum station which comprises a vacuum container in which the workpiece is located under vacuum during a working process, wherein the vacuum container has an inlet opening which is closed during the working process in substantially gas-tight manner by means of a cover arranged on the manipulating device. 
     
     
         10 . A cleaning plant in accordance with  claim 1 , wherein the workpiece is held on the manipulating device during the treatment in the treatment area of the cleaning station. 
     
     
         11 . A cleaning plant in accordance with  claim 10 , wherein the workpiece is movable relative to a treatment device of the cleaning station by means of the manipulating device during the treatment in the treatment area of the cleaning station. 
     
     
         12 . A cleaning plant in accordance with  claim 11 , wherein the workpiece is moveable relative to jets of washing agent by means of the manipulating device. 
     
     
         13 . A cleaning plant in accordance with  claim 1 , wherein the cleaning plant comprises a workpiece retaining plate on which the workpiece is held securely against a displacement. 
     
     
         14 . A cleaning plant in accordance with  claim 13 , wherein the workpiece is held on the workpiece retaining plate securely against a displacement in a horizontal direction. 
     
     
         15 . A cleaning plant in accordance with  claim 1 , wherein the washing vessel is provided, at an inner side thereof, with spraying nozzles. 
     
     
         16 . A cleaning plant in accordance with  claim 15 , wherein the spraying nozzles are formed into a plurality of groups of spraying nozzles. 
     
     
         17 . A cleaning plant in accordance with  claim 15 , wherein the washing vessel is filled with a liquid cleaning agent up to a level lying above the spraying nozzles. 
     
     
         18 . A cleaning plant in accordance with  claim 1 , wherein the spraying lance comprises a spraying lance pipe, at whose end there are arranged a multiplicity of spraying openings which point in the radial direction.
