Packaging Machine

Abstract

Machine for packaging products having parallelepiped shape, comprising a translating organ ( 1; 2 ) apt to translate a block of products, formed by stacks placed side by side of products, by exerting a push on at least one face of the block, said translating organ ( 1; 2 ) comprising at least two mutually mobile pushing members ( 3; 4 ) so as to implement a push distribution which can be adapted to the size of the block face whereon the push must be exerted to obtain the block translation.

1 . Machine for packaging products having a parallelepiped shape, comprising a translation organ ( 1 ;  2 ) apt to translate a block of products, formed by stacks placed side by side of products, by exerting a push on at least a block face, characterized in that said translation organ ( 1 ;  2 ) comprises at least two mutually mobile pushing members ( 3 ;  4 ) so as to implement a push distribution which can be adapted to the size of the block face whereon the push must be exerted to obtain the block translation. 
   
   
       2 . The packaging machine according to  claim 1 , characterized in that said pushing members of the translation organ ( 1 ) comprise at least two blades ( 3 ) which have a variable mutual distance. 
   
   
       3 . The packaging machine according to the previous claim, characterized in that it comprises at least three blades ( 3 ) with elongated shape and substantially parallel, the surface thereof results to be tangent to a same plane. 
   
   
       4 . The packaging machine according to  claim 1 , characterized in that said translation organ comprises a fork ( 2 ), the pushing members comprising the prongs ( 4 ) of said fork ( 2 ). 
   
   
       5 . The packaging machine according to  claim 3  or  4 , characterized in that it comprises a spacing organ ( 5 ;  6 ) connecting said pushing members ( 3 ;  4 ) so as to allow to vary the mutual distances between the pushing members ( 3 ;  4 ), by keeping substantially equal the distances between two subsequent pushing members ( 3 ;  4 ). 
   
   
       6 . The packaging machine according to the preceding claim, characterized in that said spacing organ ( 5 ) is actuated by an engine. 
   
   
       7 . The packaging machine according to  claim 4 , characterized in that said prongs ( 4 ) have a flat and elongated shape with thickness smaller than 2 cm. 
   
   
       8 . The packaging machine according to  claim 5 , characterized in that it comprises at least a bent lever ( 13 ) apt to close at least a tab of a box above the prongs ( 4 ) of the fork ( 2 ). 
   
   
       9 . Process for packaging products arranged in blocks formed by stacks placed side by side comprising the translation of a block by means of a translation organ ( 1 ;  2 ), which comprises at least two mutually mobile pushing members ( 3 ;  4 ) and apt to exert a push on a face of the block to be translated, characterized in that before starting the translation of the block, said pushing members ( 3 ;  4 ) are moved one with respect to the other one and arranged so as to adapt the push distribution to the sizes of the block face whereon the push is wanted to be exerted. 
   
   
       10 . The process for packaging products according to the preceding claim, characterized in that said pushing members ( 3 ;  4 ) in number greater than or equal to three, with elongated shape, parallel and coplanar, are moved so as to vary the mutual distance thereof by keeping substantially equal the distances between two subsequent pushing members.
