Injection drug packaging device

An injection drug packaging device comprising:

• a first mouth-opening unit for opening a mouth of each of a plurality of continuously supplied drug bags,
• said first mouth-opening unit being operable to open the mouth of the drug bag by sucking the bag from opposite sides of the drug bag;
• a second mouth-opening unit adapted to be inserted into the mouth of the bag to further widen the mouth of the drug bag opened by said first mouth-opening unit;
• and
• a feed unit for feeding injection drugs into each of the drug bags through the bag mouth, said feed unit comprising a belt conveyor having a delivery end and a feeding end,
• said belt conveyor having a belt trained around rollers provided at the delivery and feeding ends,
• said belt conveyor being arranged horizontally so as to move injection drugs in a horizontal direction,
• wherein said entire belt conveyor is movable substantially horizontally along a longitudinal direction thereof, relative to said first mouth opening unit, between a first position at which the delivery end of said belt conveyor can be located in the mouth of an opened bag, and a second position at which the delivery end of said belt conveyor is retracted from the first position,
• wherein said second mouth-opening unit comprises an arm mounted on said belt conveyor so as to be horizontally movable together with said belt conveyor,
• wherein said arm has a free end and is pivotal between a first arm position in which the free end is in contact with a top surface of said belt, and a second arm position in which the free end is raised from the top surface of said belt.

An injection drug packaging device comprising:

• a packaging bed for receiving a drug bag;
• a first mouth-opening device, positioned adjacent said packaging bed, for opening a mouth of the drug bag that has been received on said packaging bed, said first mouth-opening device being operable to open the mouth of the drug bag by sucking the bag from opposite sides of the drug bag;
• a second mouth-opening device adapted to be inserted into the mouth of the bag to further widen the mouth of the drug bag opened by said first mouth-opening means;
• and
• a feed unit for feeding drugs into each of the drug bags through an opened mouth of the drug bag, said feed unit comprising an endless conveyor having a delivery end and a feeding end, said endless conveyor being arranged horizontally so as to move the drugs in a horizontal direction,
• wherein said endless conveyor is movable, substantially horizontally along a longitudinal direction thereof, toward and away from said packaging bed so that the delivery end of said endless conveyor can be positioned in the opened mouth of the drug bag in order to deliver drugs into the drug bag,
• wherein said second mouth-opening device comprises an arm mounted on said endless conveyor so as to be horizontally movable together with said endless conveyor,
• wherein said arm has a free end and is pivotal between a first position in which the free end is in contact with a top surface of said endless conveyor, and a second position in which the free end is raised from the top surface of said endless conveyor,
• wherein said second mouth opening device further includes a mechanism for moving said arm from the first position to the second position when the delivery end of said endless conveyor is positioned in the opened mouth of the drug bag, said arm being maintained in said first position until the delivery end of said endless conveyor is positioned in the opened mouth of the drug bag.
