Abstract

Method of emptying a container filled with rod-like articles manufactured in the tobacco industry comprising the following stages: the container to be emptied is delivered to the entrance area of an intermediate store comprising adjacent channels separated from one another by walls; the rod-like articles are transferred by supporting plates from the container to the channels of the intermediate store; the channels of the intermediate store are filled with the rod-like articles; characterised in that during the transfer of the rod-like articles from the container to the channels of the intermediate store the intermediate store makes a reciprocating motion in the horizontal direction, transversely to the axis of the rod-like articles.

First claim

The invention claimed is:

1. Method of emptying a container filled with cylindrical articles manufactured in the tobacco industry comprising the following steps:
a container to be emptied is delivered to the entrance area of an intermediate store comprising adjacent channels separated from one another by walls;
by means of supporting plates cylindrical articles are transferred from the container to the channels of the intermediate store;
the channels of the intermediate store are filled with the cylindrical articles;
characterised in that

during the transfer of the cylindrical articles (R) from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the intermediate store ( 2 ) and the supporting plates ( 9 ) are put in a reciprocating motion in the horizontal direction, transversely to the axis of the cylindrical articles by a drive element ( 27 ) and wherein the reciprocating motion of the supporting plates ( 9 ) is synchronized with the reciprocating motion of the intermediate store ( 2 ), so that the supporting plates ( 9 ) and the intermediate store ( 2 ) are moving with the same frequency and size of travel.

2. Method as in claim 1 characterised in that during the transfer of the cylindrical articles (R) from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the intermediate store ( 2 ) makes a reciprocating motion with a stroke principally equal to the size of the diameter of cylindrical articles.

3. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the intermediate store ( 2 ) makes a reciprocating motion with a stroke between 2 and 40 mm, preferably between 4 and 8 mm.

4. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the intermediate store ( 2 ) makes principally as many full cycles of the reciprocating motion as the number of layers of the cylindrical articles situated in the filled container.

5. Method as in claim 1 characterised in that during the transfer of the cylindrical articles (R) from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the number of full cycles of the reciprocating motion made by the intermediate store ( 2 ) is greater than the number of layers of the cylindrical articles situated in the filled container.

6. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) the number of full cycles of the reciprocating motion made by the intermediate store ( 2 ) is smaller than the number of layers of the cylindrical articles situated in the filled container.

7. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) a frequency of the reciprocating motions is principally proportional to the speed of transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ).

8. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) a frequency of the reciprocating motions is constant.

9. Method as in claim 1 characterised in that during the transfer of the cylindrical articles from the container ( 5 ) to the channels ( 7 ) of the intermediate store ( 2 ) a frequency of the reciprocating motions is variable.
