Device for feeding caps with integrated buffer

Abstract

Device for feeding caps to a capping machine, comprising a cap transport route along which the caps advance In a continuous fashion between an entrance section and an exit section, in which the transport route contains a mobile buffer stock of caps advancing jointly as the caps leave said exit section. The transport route is provided with a plurality of holes to supply jets of air such as to cause the caps to advance jointly along the transport route.

1 . Device for feeding caps to a capping machine, comprising a cap transport route along which the caps advance in a continuous fashion between an entrance section and an exit section, In which the transport route contains a mobile buffer stock of caps advancing jointly as the caps leave said exit section, the transport route being provided with a plurality of holes supplying air jets causing said caps to advance jointly along the transport route. 
   
   
       2 . Feeding device according to  claim 1 , wherein the transport route comprises an advancement guide extending along a serpentine route including a plurality of straight sections linked in series one to the next through a plurality of arched sections. 
   
   
       3 . Feeding device according to  claim 2 , wherein the advancement guide is contained on a plane inclined along the direction of advancement of the caps from a higher to a lower level. 
   
   
       4 . Feeding device according to  claim 2 , including a chamber for distributing air under pressure, said chamber being provided with a plurality of holes through which air jets exit so as to cause the caps to advance along the advancement guide. 
   
   
       5 . Feeding device according to  claim 4 , wherein said chamber extends along the route of the advancement guide. 
   
   
       6 . Feeding device according to  claim 5 , wherein the distribution chamber has an upper wall provided with said holes, said upper wall forming a bottom wall of the advancement guide. 
   
   
       7 . Feeding device according  claim 1 , characterised in that the transport route includes an entrance and an exit for a flow of washing water. 
   
   
       8 . Device for washing and/or drying caps for containers, including a cap transport route along which the caps advance In a continuous fashion between an entrance section and an exit section, in which the transport route contains a mobile buffer stock of caps advancing jointly as the caps leave said exit section.
