DESCRIPTION:

BRIEF SUMMARY
The invention concerns a method in handling of returnable bottles and a device for handling of returnable bottles.
From prior art, a method for handling of returnable bottles is known wherein the returnable bottle is dropped from an upper shop space into a lower storage space vertically through a tube. In said arrangement, a problem consists of the further transfer of the returnable bottles from the position below the tube onto a storage table or to some other, corresponding storage space. Various revolving table solutions are known, from which the returnable bottle is transferred further off onto a conveyor.
From the point of view of the construction, the prior art solutions are not particularly advantageous. The cost of equipment becomes high when various counter-parts are employed for the shifting-off of the bottles.
Thus, the object of the present invention is to provide an improvement for said problem of shifting off.
The object of the invention has been achieved by means of a solution of equipment wherein it has been realized to use a rotatable brush for further transfer of the bottles.
The method in accordance with the invention is mainly characterized in that the returnable bottle is dropped through the tube into the space between the bristles in a transfer brush and a guide part and transferred out of said drop space further away, being shifted by the bristles or equivalent in the rotatable brush.
The device in accordance with the invention is mainly characterized in that, in a position below the tube, the device comprises a brush, by means of whose rotation the returnable bottle, which has fallen down through the tube, is transferred away from the position underneath the tube.
In the following, the invention will be described with reference to some preferred embodiments of the invention illustrated in the figures in the accompanying drawings, the invention being, however, not supposed to be confined to said embodiments alone.
FIG. 1A shows a first advantageous embodiment of the device in accordance with the invention viewed from above.
FIG. 1B is a partly schematical side view of the device in accordance with the invention shown in FIG. 1.
FIG. 1C is a side view of a second embodiment of the device in accordance with the invention.
FIG. 2A shows a third embodiment of the device in accordance with the invention viewed from above.
FIG. 2B shows an advantageous solution of the drive of the brushes as shown in FIG. 2A viewed from above.
FIG. 1A shows a device 10 in accordance with the invention for handling of returnable bottles. The returnable bottle is dropped from an upper space into a lower space vertically through a dropping tube 11. In the solution in accordance with the invention the returnable bottle P is dropped into a drop space C.sub.1 placed between the bristles 12a in a transfer brush 12 and the curved guide part 17a of a guide 17. The transfer brush 12 is rotated by rotating the shaft 12b of the transfer brush 12 by means of a drive motor 13 by the intermediate of a transmission 14, advantageously a bevel gear. The output shaft 15 of the transmission 14 is connected to the shaft 12b of the brush 12 by means of coupling flanges 16a,16b (in FIG. 1B).
The shaft 12b of the brush 12 is rotated around its geometric axis X.sub.1 by means of the drive motor 13. The axes of the bristles 12a in the brush 12 are placed substantially perpendicularly to the geometric axis X.sub.1.
The guide 17 comprises a curved guide part 17a and a connected straight guide part 17b. The curve radius R.sub.1 of the guide 17 is substantially equal to the distance R.sub.2 of the ends of the bristles 12a in the transfer brush 12 from the geometric axis X.sub.1. The brush 12 is fitted so in relation to the guide 17 that the ends of the bristles 12a in the brush 12 are placed at a certain distance from the curved guide part 17a of the guide 17. Thus, when the transfer brush 12 is rotated in the direction indicated by the arrow L.sub.1, the returnable bottle P is shifted from the position underneath the tube 11 forwards o
