Abstract
A carton delivery apparatus is disclosed which removes cartons, one by one, which are already scored and stored in a stack in a magazine, as folded down flat against each other. A suction mechanism removes cartons one by one from the magazine by holding it attracted thereto and delivers it to a conveyer. The suction mechanism is mounted on a rotatable member which is rotatable about a horizontal shaft disposed between the magazine and the conveyer. The suction mechanism is also rockable about a support shaft which is mounted on the member so that as the member rotates, the suction mechanism removes a carton and deliver it to the conveyer while holding it attracted thereto on its lower side.
Claims11
An apparatus for erecting cartons, comprising:
- a magazine having collapsed cartons stored therein, an outlet opening on said magazine from which stored cartons can be removed, an elongated conveyor having at least one sprocket means rotatable about a first axis of rotation, and a conveyor element guided by said sprocket means, said conveyor element having conveying means thereon oriented a finite distance from said outlet opening on said magazine and adapted to support an opened carton thereon, a primary shaft having a second axis of rotation oriented between said outlet opening on said magazine and said conveying means and parallel to said first axis of rotation, a rotatable member continuously rotatable about said second axis of rotation of said primary shaft, a plurality of circumferentially spaced suction mechanisms mounted on said rotatable member and rotatable therewith, plural support means for supporting each of said suction mechanisms for rotation relative to said rotatable member and about axes remote from and parallel to said second axis of rotation of said primary shaft, said suction mechanisms having suction means for releasably gripping said collapsed cartons at said outlet opening on an attachment side thereof, and carton manipulating means for effecting a movement of said suction mechanisms relative to said rotatable member to remove said collapsed cartons from said magazine, open said collapsed cartons to an erected condition and delivering open and erected cartons to said conveyor with said attachment side of said cartons facing said conveying means, said conveying means including laterally spaced conveyor members adapted to engage and support said open and erected carton following a delivery thereto by said continuously rotating rotatable member and said suction mechanisms moving therewith, each said suction mechanism including carton positioning means supporting said suction means for movement, in response to the control of said suction mechanism provided by said carton manipulating means, into and out of a region between said laterally spaced conveyor members to facilitate and orienting of each of said erected carton in an upstanding relation above said suction mechanism as a release of said suction mechanism from said erected carton occurs leaving said erected carton supported on said laterally spaced conveyor members, said lateral spacing thereby facilitating a maintaining of said finite distance between said outlet opening and said conveyor members even when different height cartons are presented to said outlet opening and said laterally spaced conveyor members.
