Abstract
A method of closing boxes in which the open-ended boxes and covers are sequentially fed to a box-closing station with the top of each cover overlying the open end of the box. Fitting-leaves are interposed between the outer face of the open end of the box, and the inner face of the peripheral side wall of the cover, while relative movement is effected between the cover and the box towards each other, such as to fit the cover over the open end of the box. The apparatus includes a lift which raises the box into fitted engagement with the cover supported on the fitting-leaves at the box-closing station.
Claims12
A method of closing open-ended boxes of rectangular configuration with covers of corresponding compensation, characterized in:
- sequentially feeding said boxes to a box-closing station;
- sequentially feeding said covers to said box-closing station, each of which covers has a top wall and a peripheral side wall and is fed such that its top wall overlies the open end of the box at the box-closing station;
- interposing fitting-leaf means between the outer face of the open end of the box and the inner face of the peripheral side wall of the cover aligned therewith at the box-closing station, while effecting relative movement between the cover and the box towards each other to fit the cover over the open end of the box as guided by said fitting-leaf means;
- said fitting-means including leaves extending along three sides of the box, and the relative movement between the box and cover being effected while the cover is at an incline with respect to the box such that the open end of the box is first received within the cover from a fourth side of the box not provided with a fitting leaf;
- and
- withdrawing said fitting-leaf means from between the side wall of the cover and the box closed thereby.
Apparatus for closing boxes with covers comprising:
- box feeding means for sequentially feeding open-ended boxes of rectangular configuration to a box-closing station;
- cover feeding means for sequentially feeding covers to said box-closing station, each of which covers has a top wall and a peripheral side wall, and is fed such that its top wall overlies the open end of the box in said box-closing station;
- drive means for effecting relative movement between the box and the cover towards each other;
- and
- fitting-leaf means disposed such as to be interposed between the outer face of the open end of the box and the inner face of the peripheral side wall of the cover while the relative movement is effected between the cover and the box towards each other to fit the cover over the open end of the box;
- said fitting-leaf means comprising three fitting-leaves, one extending along each of three sides of the box;
- and means mounting said fitting-leaf means to support the cover over the box in the box-closing station at an incline with respect to the box, such that when the drive means raises the box towards the cover, a fourth side of the open end of the box not provided with a fitting-leaf is received within the open end of the cover before the opposite side of the box.
Apparatus according to Chamber 4, wherein said drive comprises a reciprocating piston-and-cylinder reciprocating fluid motor.
