Apparatus for recovering pieces of paste made of active matter for plates of lead accumulators

Abstract

Apparatus for recovering pieces of paste made of active matter for plates of lead accumulators, which comprises:—a first conveyor belt wound in a loop on rollers, equipped with a first horizontal section, adapted to receive the pieces from a spreading machine, and with a first vertical section arranged to continue the first horizontal section;—a second conveyor belt wound in a loop on rollers, equipped with a second horizontal section, adapted to transfer the pieces to the hopper of the spreading machine and with a second substantially vertical section arranged to continue the second horizontal section. The two vertical sections of the two conveyor belts are arranged one on the other counterfaced to each other, parallel to hold and transport the pieces interposed therebetween and coming from the first horizontal section of the first conveyor belt and are transferred to the second horizontal section of the second conveyor belt. A third conveyor belt wound in a loop on third rollers, is arranged substantially transverse to the second horizontal section of the second conveyor belt and it is suitable to receive the pieces from the latter and transfer them to the hopper of the spreading machine.

 at least one second conveyor belt mounted on said support structure, wound in a loop over at least second rollers, and equipped with a second substantially horizontal section, suitable for giving up the pieces, at a second end roller thereof, in particular to a hopper of said spreading machine, and with at least one second substantially vertical section, arranged as a continuation of said second horizontal section; said at least first and second vertical section, respectively of said first and second conveyor belt, being arranged one on top of the other facing one another, parallel to hold and transport pieces arranged between them, at least from the first horizontal section of said first conveyor belt up to the second horizontal section of said second conveyor belt; 
 at least one third conveyor belt wound in a loop on third rollers, arranged substantially transversally to the second horizontal section of said second conveyor belt able to receive said pieces at a first end thereof from said second horizontal section and give them up to the hopper of said spreading machine at a second end thereof. 
   
     
     
         2 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said first conveyor belt is provided with a third horizontal section arranged as a continuation of its first vertical section and arranged opposite, parallel on at least one portion of the second horizontal section of said second conveyor belt to hold and transport pieces arranged between the aforementioned second and third horizontal section. 
     
     
         3 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said second conveyor belt is provided with a fourth horizontal section arranged as a continuation of its second vertical section and arranged opposite, parallel on at least one portion of the first horizontal section of said first conveyor belt to hold and transport pieces arranged between the aforementioned first and fourth horizontal section. 
     
     
         4 . Apparatus for recovering pieces of paste according to  claim 1 , wherein the first vertical section of said first conveyor belt and the second vertical section of said conveyor belt are wound over a first and second shared return roller. 
     
     
         5 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said first conveyor belt is wound in a loop over first end rollers, one upper and one lower, at least one of which is motorised. 
     
     
         6 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said first conveyor belt is wound in a loop on second end rollers one upper and one lower, at least one of which is motorised. 
     
     
         7 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said third conveyor belt is slidingly mobile along the transversal direction of its extension between a first position, in which its first end is at the second upper end roller of said second conveyor belt and a second position, in which its first end is taken away from the second upper end roller of said second conveyor belt. 
     
     
         8 . Apparatus for recovering pieces of paste according to  claim 1 , wherein said third conveyor belt is rotatably mobile around a substantially vertical axis between a first position, in which said third conveyor belt extends transversally with respect to the second horizontal section of said second conveyor belt and a second position, in which said third conveyor belt is arranged in an angled position with respect to said first position. 
     
     
         9 . Apparatus for recovering pieces of paste, according to  claim 1 , wherein: the first vertical section of said first conveyor belt and the second vertical section of said second conveyor belt are wound on a first and a second return roller in common; said first conveyor belt is wound in a loop on first end rollers, one of which upper and one lower, one of which is motor driven; and said first conveyor belt is wound in a loop with parallel paths on two first end rollers, on said first and second return roller, and on a third and a fourth return roller respectively arranged in the vicinity of said first and second return roller and at the same height respectively of said first lower end roller and first upper end roller. 
     
     
         10 . Apparatus for recovering pieces of paste, according to  claim 1 , wherein: the first vertical section of said first conveyor belt and the second vertical section of said second conveyor belt are wound on a first and a second return roller in common; said first conveyor belt is wound in a loop on second end rollers, one of which upper and one lower, one of which at least is motor driven; and said second conveyor belt is wound in a loop with parallel paths on said second end rollers, on said first and second return roller, and on a fifth and a sixth return roller respectively arranged in the vicinity of said first and second return roller and at the same height respectively of said second lower end roller and second upper end roller.
