Drug packing apparatus
First Claim
1. A drug packing apparatus comprising a hopper, and a plurality of feeders provided over the hopper for holding different kinds of drugs, said feeders being adapted to drop drugs contained in each of said feeders onto said hopper such that the drugs can be discharged from said hopper through a discharge hole formed in said hopper to pack the drugs, characterized in thatsaid apparatus further comprises a hopper opening means for opening and closing said discharge hole of said hopper,at least one intermediate drug stopper for temporarily stopping the drugs discharged from said feeders and then dropping them onto said hopper, anda control means for controlling said feeders, said intermediate drug stopper and said hopper opening means to drop drugs from said feeders onto said intermediate drug stopper, to hold the drugs temporarily on said intermediate stopper, to drop the drugs from said intermediate drug stopper onto said hopper, to hold the drugs on said hopper opening means, and to activate said hopper opening means, thereby discharging the drugs through said hopper discharge hole,said control means being adapted to compare the time period taken for each drug to drop from said each feeder onto said intermediate drug stopper with the time period taken for each drug to drop from said intermediate drug stopper onto said hopper opening means, and to activate said intermediate drug stopper and said hopper opening means simultaneously when the longer one of said two time periods has passed to drop the drugs on said intermediate drug stopper and said hopper opening means.

Abstract
A drug packing apparatus capable of packing drug efficiently irrespective of the distances between a drug packing position and drug storage positions. Drugs dropped from one of a plurality of feeders in one of a plurality of feeder units are stopped by a first intermediate impeller. The drugs are then dropped onto a second intermediate impeller, and then into a discharge hole in a hopper and stopped by a hopper cover. By opening the hopper cover, the drugs on the hopper cover drop into the folded packing sheet. By rotating heater rollers by 180°, a pouch is formed with the drugs packed therein.
