Abstract
A method and apparatus for resolving doubles on singulated flat articles being passed in a downstream direction to a takeaway mechanism by use of a doubles resolver mechanism ahead of the takeaway mechanism. The doubles resolver mechanism includes a doubles resolver head through which negative pressure may be applied to articles passing thereunder, and a mount for the head which positions the head against such articles with a substantially constant force regardless of the thickness of the article. Negative pressure is applied to the head except when the head is detected as having resolved a double, at which time such pressure is momentarily removed to permit the double to be cleared.
Claims20
In a system for passing a singulated flat article in a downstream direction from a singulation mechanism to a take-away mechanism, each of said mechanisms applying drive to a first side of each article, a doubles resolver mechanism including:
- a doubles resolver head, said head including a mechanism for selectively applying negative pressure to an operative surface thereof;
- and
- a mount for said head, said mount positioning said operative surface of the head against a second side of each article, which second side is opposite said first side, as each article passes between said singulation mechanism and said take-away mechanism, said mount pressing said head against each article with a force which is substantially constant regardless of the thickness of the article.
In a system for passing a singulated flat article in a downstream direction from a singulation mechanism to a take-away mechanism, each of said mechanisms applying drive to a first side of each article, a method for resolving doubles including:
- mounting a doubles resolver head having a mechanism for applying negative pressure to an operative surface thereof between said singulation mechanism and said take-away mechanism with a second side of each article, which second side is opposite of said first side, against each article as the article passes under the head;
- and
- pressing said head against each article with a force which is substantially constant regardless of the thickness of the article.
In a system for passing a singulated flat article in a downstream direction from a singulation mechanism to a take-away mechanism, each of said mechanisms applying drive to a first side of each article, a doubles resolver mechanism including:
- a doubles resolver head, said head including a mechanism in which normally applies negative pressure to an operative surface thereof;
- and
- a mount for said head unit mount positioning said operative surface of the head against a second side of each article, which second side is opposite said first side, as each article passes between said singulation mechanism and said take-away mechanism;
- said head separating and holding a doubled article, said negative pressure being cut off when a doubled article is detected as being said head.
