The subject of the present invention is a bottle cleaning device, in which the brushes cleaning the inside of the bottle rotate in alternating directions move.

The inner brush is particularly effective at the moment in which it their direction of rotation "reverses, because here the bristles curved to one side

ίο bend to the other side and this always under a particularly strong pressure of the bristles against the inner bottle wall must be done. To now this inversion · of the bristles always on another To allow place of the inner bottle wall, is according to the present invention also the bottle is inevitably set in rotation, so that with the appropriate choice of Rotational speeds of the bottle due to the transmission ratios and inner brush the turning point continuously on the inner bottle wall continues to migrate.

In the drawing, the device is shown in an exemplary embodiment, namely in Fig. 1 in plan view, in Fig. 2 in vertical section along line AA of Fig. 1 and in Fig. 3 in vertical section along line BB of Fig. 1, while FIG. 4 schematically illustrates the action of the inner brush at the reversal points.

The brushes b for cleaning the inside of the bottle, the brushes c for cleaning the outer surface of the bottles and the brushes d for cleaning the bottoms of the bottles are arranged in the washing container α of the device, which is filled to a certain height with washing liquid.

The bottles are placed on the brushes b, which are designed to be articulated in the shape of a square, after they have been folded up, whereupon they are folded back with the bottles into the horizontal position. Here, the bottles lay on the bearing rollers e , which bezw for support. Carrying the bottles serve, while the bottoms of the latter rest against the brushes d.

The rotation of the bottles is effected by means of rollers or rollers f which are arranged on shafts g.

The axes of the brushes b and c as well as the shafts g carrying the rollers f are set in rotation by means of a drive shaft h , and because of the arrangement made, the direction of rotation of the brushes c as well as the attached bottles is constant. Since the direction of rotation of the brushes c corresponds to that of the bottles, the brushes and bottles move in opposite directions to one another at the points of contact and the outer brushes thereby exert a good cleaning effect. The alternating rotary movement of the inner brushes b is brought about by an eccentric disk i arranged on the shaft / 2, which is coupled by an arm / to a rack k , which is mounted displaceably in a horizontal plane.

Claims (1)

The toothed wheels m , which mesh with the toothed rack k , are attached to the extended axes of the brushes b . When the shaft h is driven by means of the belt pulley η or the like, the eccentric disk i is also moved, which by means of the reciprocating rack k sets the drives in and the brushes b in alternating rotary motion. ίο The transmission ratios of the individual drive parts are chosen so that the swinging of the brushes b is much faster than the rotation of the bottles, so that even during the period in which the inner brush moves in the same direction as the bottle, the Brush ahead of the bottle. However, the bristles of the inner brushes exert a particularly powerful cleaning effect on the inner bottle wall at the moment when their direction of rotation is reversed. A schematic representation of this mode of operation is shown in FIG. 4. A tuft of bristles I have its extreme swing position in one direction, with II the extreme swing position in the other direction of rotation. The bottle moves in the direction indicated by the outer arrow. In Position I now touch the tuft of bristles on the inner bottle wall at point 1, where it is it pushed through as a result of the reversal of the direction of the brush in the dotted position will. The bristle ends exert a strong pressure on the bottle wall the end. On the way back, the tuft of bristles in position II should be reversed at about point S. the The rotation speeds of the bottle and inner brush are selected so that the The tuft of bristles is reversed as it rotates backwards into the previous position no longer in point I, but about in point 2, so that accordingly the next reversal of the tuft of bristles in point 6 and so on in points 3, 7, 4, 8, 5, 9, 6, 10 etc. takes place, whereby, if the division of these points of contact is suitable as a result The chosen rotation ratio is not exactly a multiple of the inner bottle periphery forms, the subsequently touched points are always offset from the previously touched ones, such as B. Point 10 between 1 and 2, point Ii between 2 and 3, etc., so that every point of the inner bottle of the strong action of the bristles at their reversal points and thereby a thorough and complete cleaning of the bottle is achieved. Pate nt-A ν SPRU c η: Device for cleaning bottles, in which the inner brushes alternate Moving direction of rotation, characterized in that the bottles inevitably in a non-changing direction of rotation are rotated at a different speed than the inner brushes, around the reversal point the bristles of the inner brushes always move to a different place on the work surface during the cleaning process embarrassed. 1 sheet of drawings.
