ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a packaging machine for the production of packs having at least one wrapping consisting of packaging material for the pack content, in particular of cigarette packs, the packs or their wrapping being provided by means of a coding assembly with a print, in particular, an identification code, to be changed from time to time.
2. Description of Related Art
Packs of the most diverse kinds are provided, during manufacture, with an identification code which reproduces, in particular, the time and place of manufacture. This code, usually consisting of numbers and letters, is applied in a position concealed from the user, specifically usually by printing a blank for the wrapping. In cigarette packs, the identification code is mostly applied to an inner wrapping which may consist of tin foil or paper.
The coding may be applied to blanks ready for packaging or to packs already completely or partially finished. It is expedient, however, for the identification code to be printed on a material web for manufacturing the blanks.
The identification code often has to be changed at short notice. In particular, it is necessary to change the code after each shift of the production factory.
SUMMARY OF THE INVENTION
The object on which the invention is based, in a packaging machine, in particular for the manufacture of cigarette packs, is to design a coding assembly in such a way that the code can be changed at little outlay and within a short time.
To achieve this object, the packaging machine according to the invention is characterized in that, in order to carry out changes in the printing, the coding assembly can be moved out of a working position into a freely accessible handling position.
According to the invention, therefore, the coding assembly is a unit capable of being handled separately, which, in a working position, carries out the printing of a material web or of blanks in the conventional way, but which can be moved in a simple way into a handling position, in order to carry out the adjustment of coding members.
In an advantageous embodiment of the invention, the coding members, namely coding discs rotatable on a shaft, are arranged on a preferably rotatably mounted carrier and the latter, together with the coding members, can be moved out of the working position in the axial direction. In the handling position, the coding members, which can be adjusted in order to change the print or the code, are changed. The unit or the coding assembly is subsequently moved back into the working position.
The coding assembly is arranged in a mounting or a housing which, according to the invention, is connected to an embossing block to form a unit. In the region of the embossing block, for example material webs consisting of tin foil are provided with embossing. The embossed material web then immediately thereafter runs through the coding assembly.
