Pneumatic system for the seizure and transfer of packs of products

Abstract

A pneumatic system for seizing ( 10 ) and transferring packs ( 11 ) of products, suitable for transferring packs from a feeder and inserting them into bags ( 12 ), comprising at least one opening ( 20 ) connected at one end to the suction plant ( 15 ) and having, at the other end, a pair of suction mouthpieces ( 21 ) separated by a septum ( 22 )

1 . A pneumatic system for the seizure ( 10 ) and transfer of packs ( 11 ) of products, suitable for transferring packages from a feeder and inserting them into bags ( 12 ), characterized in that it comprises at least one opening ( 20 ), connected at a first end ( 20 ′) to a suction plant ( 15 ) and having, at a second end ( 20 ″), a pair of suction mouthpieces ( 21 ) separated by a septum ( 22 ) and equipped with nozzles ( 23 ).  
   
   
       2 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein said suction mouths ( 21 ) generate a tensioning of the package container, firmly enveloping the contents, allowing a strong hold without oscillations.  
   
   
       3 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein said at least one opening ( 20 ) has tilted walls ( 27 ), which are tapered in the direction of the first end ( 20 ′) connected to the suction ( 15 ).  
   
   
       4 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein the presence of a series of openings ( 20 ) connected to the suction plant ( 15 ), is envisaged.  
   
   
       5 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein each opening ( 20 ) is supported by at least one bar ( 16 ), preferably a pair of bars ( 16 ) and is equipped with leverisms and translators ( 17 ) suitable for transferring the product from the seizure position to the insertion position.  
   
   
       6 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein each opening ( 20 ) can be rotated by about 90° C. rapidly and without using tools, guaranteeing the solidity of the hold.  
   
   
       7 . The pneumatic seizure system ( 10 ) according to  claim 1 , wherein said system is envisaged for cooperating with an insertion apparatus of packages into bags, equipped with squaring and stiffening means ( 40 ) mainly aimed at squaring the mouth of the bag and effecting the necessary stiffening to allow the rapid and precise introduction of the packages ( 11 ).  
   
   
       8 . A packaging plant equipped with a pneumatic seizure system ( 10 ) according  claim 1.
