Problems solved by technology

However, this method for detecting incorrect workpiece position can only be used at small distances (e.g. up to 3mm) between the workpiece and the nozzle
This method cannot therefore be used in situations where the workpiece holder and the tuyeres move relative to each other when the cleaning device is in operation
Furthermore, correct calibration of nozzles is difficult and time consuming

Embodiment Construction

[0057] The cleaning apparatus shown generally at 100 in FIGS. 1-7 includes a plurality of processing stations 102, each of which performs a processing step for workpiece cleaning, one of which is shown in FIGS. 1-3.

[0058] Each processing station 102 includes a fixed workpiece holder 104 as shown in FIGS. 1-3 and processing tools for performing workpiece cleaning (not shown), such as tuyeres, nozzles, movable spray guns or the like.

[0059] In order to be able to move the workpiece 106 (see FIGS. 5-7 ) to be cleaned from the fixed workpiece holder 104 of the first processing station 102 in the transport direction 108 (see FIGS. 1-3 ) to the first processing station in the transport direction 108 On the fixed workpiece holder 104 of the second processing station 102 in the back, the cleaning device 100 includes a conveying device 110 in the form of a slide-type multi-station automatic feeding device 112, which includes two slats 114 extending along the conveying direction 108...

Abstract

The invention relates to a cleaning device for cleaning workpieces (106), comprising at least one workpiece receptacle (114) for a workpiece to be cleaned. The aim of the invention is to provide a simple, flexible and reliable verification of the position of the workpiece. To achieve this, the cleaning device comprises at least one distance sensor (126) that generates a signal, said signal being used to deduce whether a workpiece is held in the correct position in the workpiece receptacle.

Description

technical field [0001] The invention relates to a cleaning device for cleaning workpieces, which comprises at least one workpiece holder for the workpiece to be cleaned. Background technique [0002] Such cleaning devices are known from the prior art. [0003] In particular, cleaning systems are known in which the correct position of the workpiece on the workpiece holder is controlled by means of a silhouette plate at the inlet of the cleaning device. In this respect, the conveying device conveys the workpieces in the conveying direction past the profile plate. The silhouette plate has a punched opening that corresponds to the contour of the workpiece. In the event of an incorrect workpiece position, the silhouette plate deflects and operates a contact-sensitive sensor. [0004] This silhouette plate must be replaced when changing the type of workpiece to be cleaned. A further difficulty is that workpieces with different outer contours are conveyed alternately through th...
