Article separating and dispensing device
The present invention relates to a more robust article dispensing apparatus that is relatively simple in construction and usage for dispensing articles in a clean and protective environment. More specifically, the apparatus accepts, separates, and dispenses articles from a nested stack of articles such as beverage cup lids one at a time. In one embodiment, a dispensing apparatus for dispensing an article from a stack of articles each having a periphery comprises an isolating device including one or more isolating members which are movable between a hold position spaced from the stack of articles, and a dispense position contacting the periphery of one or more articles in the stack and supporting the one or more articles including an adjacent article which is adjacent an endmost article while not contacting the periphery of the endmost article by the one or more isolating members, to isolate the endmost article from the other articles in the stack to permit the endmost article to be separated from the other articles and be dispensed.
1. A dispensing apparatus for dispensing an article from a stack of articles each having a periphery, the apparatus comprising:
an isolating device including one or more isolating members which are movable between a hold position spaced from the stack of articles, and a dispense position contacting the periphery of one or more articles in the stack and supporting the one or more articles including an adjacent article which is adjacent an endmost article while not contacting the periphery of the endmost article by the one or more isolating members; and
a supporting device including one or more supporting members which are movable between the hold position contacting and supporting the endmost article, and the dispense position spaced from the endmost article;
wherein the one or more isolating members in the dispense position contact the periphery of one article if the stack includes only one article which is the adjacent article in addition to the endmost article; and
wherein the one or more isolating members in the dispense position contact the peripheries of at least two articles if the stack includes a plurality of articles including the adjacent article in addition to the endmost article;
wherein the one or more isolating members comprises one or more holding pads, and wherein the one or more supporting members comprises one or more supporting pins.
2. The apparatus of claim 1 wherein the isolating device and the supporting device are coupled to synchronize movement between the hold position in which the one or more isolating members are spaced from the stack of articles and the one or more supporting members contact and support the endmost article, and the dispense position in which the one or more isolating members contact the periphery of one or more articles in the stack and support the one or more articles including an adjacent article and the one or more supporting members are spaced from the endmost article.
3. The apparatus of claim 2 wherein, during movement from the hold position to the dispense position, the one or more isolating member are configured to contact and support the periphery of the one or more articles including the adjacent article before the one or more supporting members lose contact with the endmost article.
4. The apparatus of claim 2 wherein, during movement from the dispense position to the hold position, the one or more supporting members are configured to contact and support the endmost article before the one or more isolating members lose contact with the periphery of the one or more articles.
5. The apparatus of claim 2 wherein the isolating device and the supporting device are coupled by a resilient member.
6. The apparatus of claim 1 wherein the one or more isolating members in the dispense position contact the periphery of at least one article which is adjacent to the endmost article in the stack except the endmost article and support said at least one article including the adjacent article except the endmost article.
7. The apparatus of claim 1 wherein the adjacent article and the endmost article are different sizes.
8. The apparatus of claim 7 wherein the articles are beverage lids.
9. The apparatus of claim 8 wherein the size difference between the adjacent beverage lid and the endmost beverage lid is over 2 inches.
10. The apparatus of claim 1 wherein the isolating device is located above the dispensing device.
11. The apparatus of claim 1 additionally comprising an actuation mechanism for causing movement from the hold position to the dispense position.
12. The apparatus of claim 11 wherein the actuation mechanism includes a linkage and a manual dispensing button.
13. The apparatus of claim 1 wherein the isolating device and the dispensing device rotate in the same direction when moving from the hold position to the dispense position.
