Machine for filling envelopes or bags also in controlled atmosphere

Abstract

A machine for filling bags or envelopes, also under controlled atmosphere, consisting of a prismatic wheel (G), having polygonal shape and provided on each side with at least a couple of opposite prehensile equipments (M), whose mutual horizontal distance can be regulated to handle bags or envelopes having different dimensions.

1 ) A machine for filling bags or envelopes, also under controlled atmosphere, characterized by the fact that it consists of a prismatic wheel (G), having a polygonal shape and equipped on each side with at least a couple of opposite prehensile equipments (M), wherein the mutual horizontal distance between the at least a couple of opposite prehensile equipments (M) can be regulated to handle bags or envelopes (S) having different dimensions. 
   
   
       2 ) A machine for filling bags or envelopes, also under controlled atmosphere, as in  claim 1 , characterized by the fact that on the upper basis of said prismatic wheel (G) are set up, parallel to each side of the polygon, movable bars (P) whose radial synchronized excursions determine the simultaneous opening of the couple of opposite prehensile equipments (M) and contrast the relative compression return springs (H). 
   
   
       3 ) A machine for filling bags or envelopes, also under controlled atmosphere, as in  claim 2 , characterized by the fact that the radial excursions of the movable bars (P) are actuated by internal radial pushers that exert their push (E) on the mid point of said moving bars (P) contrasting with the traction springs (K). 
   
   
       4 ) A machine for filling bags or envelopes, also under controlled atmosphere, as in  claim 1 , characterized by the fact that the opposite prehensile equipments (M), especially pivoted, are steadily inclined (M″) by the push (We) exerted on rolls (R), then later brought back steadily to the initial conditions by the push (WI) exerted on the rolls (R) with the goal of optimizing the opening or the closing of the mouths of bags and envelopes. 
   
   
       5 ) A machine for filling bags or envelopes, also under controlled atmosphere, as in  claim 1 , characterized by the fact that during the unfolding of the technological process, in the different phases of initial insertion, opening, closing, filling, re-closing and final sealing, the bag or envelope is always protected inside a bell (C; C), kept saturated by the controlled flow of inert gas (N.) 
   
   
       6 ) A machine for filling bags or envelopes as in  claim 5 , characterized by the fact that the bell has a toroidal tunnel shape. 
   
   
       7 . A machine for filling bags or envelopes comprising:
 a wheel;   a polygonal form having a plurality of sides mounted on said wheel;   opposing prehensile equipment mounted on each of the plurality of sides of said polygonal form, said opposing prehensile equipment having a horizontal distance there between, whereby a predetermined size bag may be held between said opposing prehensile equipment; and   means for adjusting the horizontal distance,   whereby the horizontal distance can be regulated to handle bags or envelopes having different dimensions.   
   
   
       8 . A machine for filling bags or envelopes as in  claim 7  further comprising:
 means for inclining a stance of said opposing prehensile equipment, whereby a mouth of the predetermined size bag is held open.   
   
   
       9 . A machine for filling bags or envelopes as in  claim 8  wherein:
 said means for inclining a stance of said opposing prehensile equipment comprises rollers.   
   
   
       10 . A machine for filling bags or envelopes as in  claim 7  further comprising:
 a bell covering said polygonal form,   whereby an inert gas can be contained while a bag or envelope is filed.   
   
   
       11 . A machine for filling bags or envelopes in a controlled atmosphere comprising:
 a wheel;   a polygonal form having a plurality of sides mounted on said wheel;   opposing prehensile equipment mounted on each of said plurality of sides of said polygonal form, said opposing prehensile equipment having a horizontal distance there between, whereby a predetermined size bag may be held between said opposing prehensile equipment;   a bell capable of holding an inert gas and open on a bottom side placed over said polygon form and said opposing prehensile equipment;   an oscillating arm provided with suction cups, said oscillating arm positioned to pivot upward towards the bottom side of said bell and place the predetermined size bag between said opposing prehensile equipment, wherein said oscillating arm picks up a predetermined size bag and orients a mouth of the predetermined size bag past the bottom side of said bell, whereby the mouth of the predetermined size bag may be held within the inert gas;   means for inclining a stance of said opposing prehensile equipment, whereby a mouth of the predetermined size bag is held open;   means for filing the predetermined size bag; and   means for sealing the predetermined size bag,   whereby the predetermined size bag is held open, filed, and sealed in the inert gas or controlled atmosphere.
