Abstract
A feeding device is adapted to be installed to a box folding machine for delivering a plurality of unfolded cardboard boxes, and includes a base unit, a positioning unit and a box pushing unit. The base unit is operable for moving the cardboard boxes to push two stopping members of the positioning unit to rotate from a stopping position, where the cardboard boxes are retained between upstream and downstream ends of the base unit, to a releasing position, where one of the cardboard boxes is moved out of the downstream end to a standby position. The box pushing unit is operable to push the one of the cardboard boxes from the standby position to a ready-to-fold position, where the one of the cardboard boxes is ready to be folded.
Claims8
A feeding device adapted to be installed to a box folding machine for delivering a plurality of unfolded cardboard boxes, said feeding device comprising:
- a base unit including
- a machine body that has
- top and bottom surfaces being opposite to each other along a vertical direction and extending from an upstream end of said machine body to a downstream end of said machine body along a first horizontal direction which is perpendicular to the vertical direction, and
- a side surface formed at said downstream end, and extending between and being perpendicular to said top and bottom surfaces,
- a conveyor group that is mounted to said top surface of said machine body for conveying the cardboard boxes along the first horizontal direction, and
- a support group that is mounted to said machine body, and that has a support surface connected perpendicularly to said side surface of said machine body, and extending between and being parallel to said top and bottom surfaces of said machine body;
- a positioning unit including
- two stopping members that are mounted rotatably to said downstream end of said machine body, and that are spaced apart in a second horizontal direction perpendicular to the first horizontal direction and the vertical direction, said conveyor group being operable for moving the cardboard boxes to push said stopping members to rotate from a stopping position, where the cardboard boxes are retained between said upstream and downstream ends of said machine body, to a releasing position, where one of the cardboard boxes is moved out of said downstream end of said machine body to a standby position to be clamped between said stopping members and the remainder of the cardboard boxes, and
- two first springs, each of said first springs being connected between a respective one of said stopping members and said machine body for biasing said respective one of said stopping members toward the stopping position;
- and
- a box pushing unit including
- a frame member that is mounted to said downstream end of said machine body,
- a mounting seat that is mounted to said frame member and that is movable along the vertical direction relative to said machine body,
- a drive group that is connected to said frame member for driving the movement of said mounting seat along the vertical direction, and
- at least one pushing group that is co-movably mounted to said mounting seat such that the movement of said mounting seat along the vertical direction moves said at least one pushing group to push the one of the cardboard boxes along the vertical direction from the standby position to a ready-to-fold position, where the one of the cardboard boxes abuts against said support surface of said support group.
