Equipment and method for the packaging of packets of products in bags

Abstract

Equipment ( 10 ) for the packaging of packets ( 11 ) in bags ( 12 ) comprises a bag forming device ( 13 ), a transfer line ( 14 ) of the formed bags by means of a conveyor with independent trolleys or drawers or independent compartments, a feeding line of packets of products ( 15 ), an accumulation and desynchronization area ( 20 ), a filling station ( 30 ) operating by means of an insertion device ( 40 ) of the packets into bags, and a closing station ( 50 ) of the bags filled with packets.

1 . Equipment ( 10 ) for the packaging of packets of products ( 11 ) in bags ( 12 ), characterized in that it comprises a bag forming device ( 13 ), a transfer line ( 14 ) of the formed bags by means of a conveyor with independent trolleys or drawers or independent compartments, a feeding line of packets of products ( 15 ), an accumulation and desynchronization area ( 20 ), a filling station ( 30 ) operating by means of an insertion device ( 40 ) of the packets into bags, and a closing station ( 50 ) of the bags filled with packets.  
   
   
       2 . Packaging equipment ( 10 ) according to  claim 1 , wherein the bag forming station is predisposed for operating in continuous, the filling station batchwise, the closing station in continuous.  
   
   
       3 . Packaging equipment ( 10 ) according to  claim 1 , wherein said packets ( 11 ) are of the soft type.  
   
   
       4 . Packaging equipment ( 10 ) according to  claim 1 , wherein said bags ( 12 ) are made of a plastic material such as polyethylene for food or similar, and have a limited rigidity which allows self-sustainment in an open position and in elevation.  
   
   
       5 . Packaging equipment ( 10 ) according to  claim 1 , wherein said bags ( 12 ) are preferably produced in a substantially parallelepiped form.  
   
   
       6 . Packaging equipment ( 10 ) according to  claim 1 , wherein said filling station ( 30 ) is integrated with an insertion device ( 40 ) of packets into bags, equipped with squaring and stiffening means ( 42 ) aimed at squaring the mouth of the bag and effecting the necessary stiffening for allowing the rapid and precise introduction of the packets ( 11 ) and a pneumatic system ( 41 ) for the seizure and transfer of the packets suitable for inserting them into the bags.  
   
   
       7 . A method for packaging packets of products into bags operating by means of equipment according to  claim 1 , characterized in that it comprises the following phases: 
 a) advantageously forming bags ( 12 ) in continuous;    b) positioning the formed bags ( 12 ) on independent trolleys ( 16 ) integral with a transfer line ( 14 ) of the formed bags which allows them to be accumulated;    c) feeding packets ( 11 ) of products to a feeding line ( 15 ) of packets ( 11 ) of products;    d) transferring bags ( 12 ) and packets ( 11 ) to an accumulation and desynchronization area ( 20 );    e) feeding packets ( 11 ) and bags ( 12 ) to said accumulation and desynchronization area ( 20 ) until a predefined number is reached;    f) filling the bags ( 12 ) by means of an insertion device ( 40 ) of the packets into said bags;    g) sending the filled bags ( 12 ) to a closing station ( 50 ) of the bags.    
   
   
       8 . The packaging method according to  claim 7 , wherein said packets ( 11 ) are of the soft type.  
   
   
       9 . The packaging method according to  claim 7 , wherein said bags ( 12 ) are made of plastic materials such as polyethylene for food or similar, and have a limited rigidity and substantially parallelepiped form which allows self-sustainment in an open position and in elevation.  
   
   
       10 . The packaging method according to  claim 7 , wherein said filling phase f) is effected inside said filling station ( 30 ) integrated with an insertion device ( 40 ) of packets into bags, equipped with squaring and stiffening means ( 42 ) aimed at squaring the mouth of the bag and effecting the necessary stiffening for allowing the rapid and precise introduction of the packets ( 11 ) and a pneumatic system ( 41 ) for the seizure and transfer of the packets suitable for inserting them into the bags.
