Abstract

A system for packaging mass-customized items includes a computer system including a database containing item identification information unique to each item; (2) outer container identification apparatus that applies the item identification information received from the database to each outer container in a plurality of outer containers; (3) inner pack identification apparatus that applies the item identification information received from the database to each inner pack in a plurality of inner packs; and (4) inner pack filling apparatus that fills each inner pack with a specific item matched to that inner pack by the item identification information received from the database. Each item is associated with its unique item identification information and is inserted into an inner pack with matching item identification information, and each outer container is presented for loading with one or more inner packs matched to that outer container by the item identification information received from the database.

Claims

1. Apparatus for inserting mass-customized items into bags, comprising:

a computer system having a database;

a puck conveyor configured to carry a plurality of pucks, each of the pucks carrying at least one mass-customized item associated with the puck by item-specific information stored in the database;

a bag conveyor configured to receive a plurality of bags, each of the bags having an opening defined between opposed side walls, each of the bags being associated by the computer system with the item-specific identification information identifying at least one of the mass-customized items;

a pick and place mechanism operable to move each of the mass-customized items from its associated puck on the puck conveyor to an item conveyor;

a bag opening mechanism configured to receive the plurality of bags from the bag conveyor and to open each of the bags; and

an insertion mechanism operably associated with the bag-opening mechanism and configured to receive the mass-customized items from the item conveyor and to insert each individual mass-customized item into an open bag associated by the computer system with the individual mass-customized item using the item-specific identification information in the database identifying the individual mass-customized item.

2. The apparatus of claim 1, further comprising:

a placement mechanism operable to move the mass-customized items from the item conveyor to the insertion mechanism.

3. The apparatus of claim 2, wherein the insertion mechanism includes a receiving bed configured to receive the mass-customized items from the placement mechanism, a loading channel configured to position the mass-customized items for insertion into the bags, and a pushing element operable to move the mass-customized items from the receiving bed to the loading channel.

4. The apparatus of claim 3, wherein the insertion mechanism includes a ram element configured to insert each of the mass-customized items in the loading channel into an open bag associated with the mass-customized item by the item-specific identification information.

5. The apparatus of claim 1, wherein the bag opening mechanism comprises:

a vacuum head operable to engage a side wall of each individual bag in the plurality of bags so as to open the opening of the individual bag; and

a holding element operable for insertion into the opening of the individual bag so as to keep the opening open.

6. The apparatus of claim 1, wherein each of the mass-customized items is marked with the item-specific identification information, and wherein the apparatus further comprises:

means for reading the item-specific identification information from each of the mass-customized items and transmitting the item-specific identification information to the computer system database; and

a bag printing mechanism operable to retrieve the item-specific identification information for each of the mass-customized items from the database and to apply the item-specific identification information to a bag into which the mass-customized item is to be inserted.

7. The apparatus of claim 1, wherein the mass-customized items are dental appliances.

8. The apparatus of claim 1, wherein each of the pucks is marked with the item-specific identification information associated with the at least one mass-customized item carried on the puck, and wherein the apparatus further comprises:

means for reading the item-specific identification information from each of the pucks and transmitting the item-specific identification information to the computer system database; and

a bag printing mechanism operable to retrieve the item-specific identification information for each of the mass-customized items from the database and to apply the item-specific identification information to a bag into which the at least one mass-customized item is to be inserted.

9. The apparatus of claim 1, wherein the item-specific identification information includes information identifying (a) a group for each mass-customized item, and (b) a sequential place for each mass customized item within its group.

10. Apparatus for inserting mass-customized dental appliances into bags, comprising:

a computer system having a database;

a puck conveyor configured to carry a plurality of pucks, each of the pucks carrying at least one mass-customized dental appliance associated with the puck by item-specific information stored in the database;

a bag conveyor configured to receive a plurality of bags, each of the bags having an opening defined between opposed side walls, each of the bags being associated by the computer system with the item-specific identification information identifying at least one of the mass-customized dental appliances;

a pick and place mechanism operable to move each of the mass-customized dental appliances from its associated puck on the puck conveyor to an item conveyor;

a bag opening mechanism configured to receive the plurality of bags from the bag conveyor and to open each of the bags; and

an insertion mechanism operably associated with the bag-opening mechanism and configured to receive the mass-customized dental appliances from the item conveyor and to insert each individual mass-customized dental appliance into an open bag associated by the computer system with the individual mass-customized dental appliance using the item-specific identification information in the database identifying the individual mass-customized dental appliance.

11. The apparatus of claim 10, further comprising:

a placement mechanism operable to move the dental appliances from the item conveyor to the insertion mechanism.

12. The apparatus of claim 11, wherein the insertion mechanism includes a receiving bed configured to receive the dental appliances from the placement mechanism, a loading channel configured to position the dental appliances for insertion into the bags, and a pushing element operable to move the dental appliances from the receiving bed to the loading channel.

13. The apparatus of claim 12, wherein the insertion mechanism includes a ram element configured to insert each of the dental appliances in the loading channel into an open bag associated with the dental appliance by the item-specific identification information.

14. The apparatus of claim 10, wherein the bag opening mechanism comprises:

a vacuum head operable to engage a side wall of each individual bag in the plurality of bags so as to open the opening of the individual bag; and

a holding element operable for insertion into the opening of the individual bag so as to keep the opening open.

15. The apparatus of claim 10, wherein the mass-customized dental appliances are mass-customized dental aligners.

16. The apparatus of claim 10, wherein each of the pucks is marked with the item-specific identification information associated with the at least one mass-customized dental appliance carried on the puck, and wherein the apparatus further comprises:

means for reading the item-specific identification information from each of the pucks and transmitting the item-specific identification information to the computer system database; and

a bag printing mechanism operable to retrieve the item-specific identification information for each of the pucks from the database and to apply the item-specific identification information to a bag into which the at least one mass-customized dental appliance is to be inserted.

17. The apparatus of claim 10, wherein each of the mass-customized dental appliances is marked with the item-specific identification information associated, and wherein the apparatus further comprises:
