Abstract
Abstract A container blank feeder apparatus for feeding containers in a collapsed form from a container magazine to a feeding station on a machine for erecting the containers for forming and filling operations, and which includes a base, a rotatable turret mounted on said base for rotation about a vertical axis, power means for rotating the turret at a constant angular speed in one direction, a plurality of suction cup means movably mounted for rotation about said vertical axis and for radial outward and inward movements relative to said turret for gripping and removing collapsed containers from the magazine and conveying them to said feeding station, and means operative in response to rotation of the turret about said vertical axis for rotating said suction cup means simultaneously with said turret between said container magazine and said feeding station, and for stopping each of said suction cup means at said magazine and moving them radially outward to grip a collapsed container in said magazine and thence radially inward to withdraw the container from said magazine and transfer it at constant speed to said feeding station.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
In a container blank feeder apparatus for feeding containers in a collapsed form from a container magazine to a feeding station on a machine for erecting the container for forming and filling, the combination, comprising: a. a base; b. a rotatable turret mounted on said base for rotation about an axis; c. means for rotating said turret continuously at a constant angular speed in one direction; d. at least one suction cup means for gripping and removing a collapsed container from said magazine and conveying it to said feeding station; e. means for movably mounting said suction cup means for rotation about said axis and for radial outward and inward movements relative to said turret; and, f. means operative in response to rotation of said turret about said axis for rotating said suction cup means simultaneously with said turret between said container magazine and said feeding station, and including a cam means for stopping said suction cup means at said magazine and moving it radially outward to grip a collapsed container in said magazine and thence moving it radially inward to withdraw the container from said magazine and transfer it at constant speed to said feeding station.
Claim 2
Dependent Claim
197 words
In a container blank feeder apparatus for feeding containers in a collapsed form from a container magazine to a feeding station on a machine for erecting the container for forming and filling, the combination, comprising: a. a base; b. a rotatable turret mounted on said base for rotation about an axis; c. means for rotating said turret continuously at a constant angular speed in one direction; d. at least one suction cup means for gripping and removing a collapsed container from said magazine and conveying it to said feeding station; e. means for movably mounting said suction cup means for rotation about said axis and for radial outward and inward movements relative to said turret; and, f. means operative in response to rotation of said turret about said axis for rotating said suction cup means simultaneously with said turret between said container magazine and said feeding station, and including a cam means for stopping said suction cup means at said magazine and moving it radially outward to grip a collapsed container in said magazine and thence moving it radially inward to withdraw the container from said magazine and transfer it at constant speed to said feeding station.
Claim 3
Dependent Claim
29 words
A container blank feeder apparatuS as defined in claim 1, wherein: a. said means for rotating said turret at a constant angular speed includes a power-operated gear drive means.
Claim 4
Dependent Claim
23 words
A container blank feeder apparatus as defined in claim 1, wherein: a. said feeder apparatus includes a plurality of said suction cup means.
Claim 5
Dependent Claim
48 words
A container blank feeder apparatus as defined in claim 1, including: a. means disposed adjacent said turret for engagement with a container on said suction cup means when it is moved from said magazine to said feeding station for opening and back-folding the container to open the same.
Claim 6
Dependent Claim
60 words
A container blank feeder apparatus as defined in claim 1, wherein said means for movably mounting said suction cup means comprises: a. a carrier bracket rotatably mounted on said base about said axis; b. at least one shaft fixed on said carrier bracket and extended radially outward therefrom; and, c. said suction cup means being slidably mounted on said shaft.
Claim 7
Dependent Claim
135 words
A container blank feeder apparatus as defined in claim 5, wherein said means operative in response to rotation of said turret for rotating said suction cup means, comprises: a. a first cam means mounted on said turret; b. a first cam roller mounted on said suction cup means and operatively engaged with said first cam means; c. a second cam means fixed on said base; and, d. means operatively engaged with said second cam means and operatively connected with said suction cup means, whereby said suction cup means is simultaneously moved with said turret between said container magazine and feeder station, and said suction cup means is stopped at said magazine and moved radially outward to grip a container in said magazine and thence is moved radially inward to withdraw the container from said magazine.
Claim 8
Dependent Claim
161 words
A container blank feeder apparatus as defined in claim 6, wherein said means operatively engaged with said second cam means and operatively connected with said suction cup means, comprises: a. a second cam roller mounted on said suction cup means; b. a first shaft rotatably mounted on said turret in a position spaced apart from said turret axis and parallel thereto; c. a yoke fixed on one end of said first shaft and having an elongated cam track in which is operatively received said second cam roller; d. a gear carried on the other end of said first shaft; e. a second shaft rotatably mounted on said turret in a position spaced apart from said turret axis and parallel thereto; f. a gear segment carried on said second shaft and meshed with said gear on said first shaft; and, g. a third cam roller attached to said gear segment and operatively engaged in said second cam means fixed on said base.
Claim 9
Dependent Claim
56 words
A container blank feeder apparatus as defined in claim 7, wherein said suction cup means comprises: a. a vertically disposed carrier slidably mounted on said shaft on said carrier bracket; b. a plurality of aligned suction cups operatively mounted on said carrier; and, c. said first and second cam rollers being operatively mounted on said carrier.
