Automated medication bagger system, methods, and apparatus
A method and apparatus for automated packaging medication containers and medication documentation into bags are disclosed. The bag is opened by an air knife and held open by fingers and grippers. The bag is filled with a medication container and corresponding medication documentation. The bag is then sealed shut and is ready for delivery to a patient.
1 . A packaging apparatus for a medication bagger system, the packaging apparatus comprising:
a main frame;
a bag transport mechanism affixed to the main frame and configured to receive a plurality of bags, wherein the bag transport mechanism cooperates with a motor used to transport at least one of the plurality of bags to at least a printing station and a loading station;
the printing station including at least a thermal transfer printer and a print roller; and
the loading station including at least a first articulable finger, a second articulable finger, and a third articulable finger, at least a first bag gripper and a second bag gripper, an air knife, and a sealing mechanism, wherein:
the first articulable finger, the second articulable finger, and the third articulable finger are configured to engage a leading bag of the plurality of bags to enable medication documentation and at least one medication container to be placed therein, and
the first bag gripper and second bag gripper are configured to engage the leading bag to prepare it for sealing and move away from the leading bag pulling the leading bag taut for sealing.
2 . The packaging apparatus of claim 1 , wherein the plurality of bags includes a preformed length of bags attached to one another.
3 . The packaging apparatus of claim 1 , wherein each of the plurality of bags includes a perforation on a back side of an inflation edge.
4 . The packaging apparatus of claim 3 , wherein the air knife is configured to direct air towards the inflation edge of the leading bag to open the leading bag.
5 . The packaging apparatus of claim 1 , wherein the plurality of bags is in a roll.
6 . The packaging apparatus of claim 1 , wherein the bag transport mechanism is a conveyor track.
7 . The packaging apparatus of claim 1 , wherein the bag transport mechanism is a plurality of rollers.
8 . The packaging apparatus of claim 7 , further comprising a clutch positioned along the bag transport mechanism to control the plurality of rollers from spinning loosely.
9 . The packaging apparatus of claim 1 , wherein at least a portion of the printing station is affixed to a pivotable frame.
10 . The packaging apparatus of claim 1 , wherein the first articulable finger, the second articulable finger, and the third articulable finger are moved by at least one pneumatic valve.
11 . The packaging apparatus of claim 1 , wherein the first bag gripper and the second bag gripper are configured to engage the leading bag after loading the medication documentation and the at least one medication container to translate relative one another to pull the leading bag taut.
12 . The packaging apparatus of claim 1 , wherein the loading station includes a static eliminating mechanism.
13 . The packaging apparatus of claim 12 , wherein the static eliminating mechanism is an ionizing bar.
14 . The packaging apparatus of claim 1 , wherein the sealing mechanism includes mating a heat seal bar with a silicone seal pad between a front side and a back side of the leading bag to form the seal on the leading bag.
15 . The packaging apparatus of claim 1 , further comprising an opening sensor for detecting if the leading bag has been opened.
16 . A method for packaging medication, the method comprising:
feeding a leading bag from a plurality of bags, via a motor and a bag transport mechanism, to a printing station;
printing patient information onto a front side of the leading bag at the printing station by a thermal transfer printer and a print roller;
transporting, via the bag transport mechanism, the leading bag to a loading station;
opening the leading bag with an air knife configured to blow air directly into an inflation edge of the leading bag;
engaging, via a bag gripper first and a second bag gripper configured to engage the leading bag and a first articulable finger, a second articulable finger, and a third articulable finger configured to pull the front side of the leading bag away from a back side of the leading bag;
filling the leading bag with medication documentation and at least one medication container;
moving the first bag gripper and second bag gripper apart from one another to stretch the leading bag taut; and
sealing the leading bag by a sealing mechanism.
17 . The method of claim 16 , wherein the plurality of bags includes a preformed length of bags attached to one another.
18 . The method of claim 16 , wherein each of the plurality of bags includes a perforation on the back side of the inflation edge.
19 . The method of claim 18 , further comprising reverse indexing the motor while the sealing mechanism breaks the perforation on the leading bag.
20 . The method of claim 16 , further comprising mating a heat seal bar with a silicone seal pad between the front side and back side of the leading bag to form a seal on the leading bag.
