Bag supplying apparatus for a bag-filling packaging machine

Abstract

A bag supplying apparatus for a bag-filling packaging machine, including a vibrating feeder that involves a trough in which bags are placed in a cascade fashion and a vibration driver which vibrates the trough so as to cause the bags to be conveyed forward, a positioning stopper provided at a final end of a conveying path of the bags so that the tip end of a leading bag being conveyed comes into contact with the stopper, and a suction disk that suction-chucks and lifts a bag positioned by the position stopper and feeds the bag to another location.

1 . A bag supplying apparatus for a bag-filling packaging machine, comprising: 
 a vibrating feeder that is a conveying means and includes: 
 a trough in which bags that are stacked are placed so that a bag on another bag is shifted on a forward side, and  
 a vibration driver that causes said bags to convey forward by vibrating said trough;  
   a positioning stopper with which a tip end of a leading bag comes into contact, said positioning stopper being provided at substantially a final end of a conveying path of said conveying means; and    a suction disk that suction-chucks and lifts a bag positioned by said stopper and feeds said bag to another location.    
   
   
       2 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 1 , wherein said trough includes side plates, and a gap between said side plates is adjustable.  
   
   
       3 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 1 , wherein said vibrating feeder further includes an adjustment means for adjusting an angle of inclination of said trough in a forward-rearward direction.  
   
   
       4 . The bag supplying apparatus for a bag-filling packaging machined according to  claim 1 , wherein a vibration frequency and/or amplitude of said trough of said vibrating feeder is variable.  
   
   
       5 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 1 , further comprising a detector which detects remaining quantity of bags in said trough.  
   
   
       6 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 1 , further comprising a fast-feeding belt which contacts upper surfaces of said bags conveyed in said trough and fast-feeds said bags in a forward direction.  
   
   
       7 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 1 , further comprising another conveying means which is provided at a feeding end of said vibrating feeder so as to convey said bags that have been fed out from said vibrating feeder even further forward.  
   
   
       8 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 7 , wherein said another conveying means is a belt conveyor.  
   
   
       9 . The bag supplying apparatus for a bag-filling packaging machine according to  claim 7 , wherein said another conveying means is a vibrating feeder.
