ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an aligning apparatus, more particularly to an automated aligning apparatus for aligning sides of a stack of paperboards carried toward a paperboard processing device.
2. Description of the Related Art
A conventional way to align sides of a stack of paperboards for carrying toward a paperboard processing device, such as a printing machine, is to stack the paperboards at a corner of a factory with various lines in accordance with the sizes of the paperboards, thereby resulting in the need for a relatively large operating area. A lifter is then used to move the stacked paperboards toward the processing device for machining. As such, there is a tendency that the paperboards will deviate from their aligning positions, and it is labor-intensive to perform manual alignment of the paperboards on a feeding side of the processing device. In addition, the lifter needs a relatively large space for movement.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an aligning apparatus adapted to be mounted adjacent to a paperboard processing device for aligning sides of a stack of paperboards prior to a processing operation.
According to this invention, an aligning apparatus includes a slidable carrier for carrying a paperboard stack and disposed to move along a guided straight path in a longitudinal direction from a stack aligning position to a stack feeding position. A first aligning member is disposed adjacent to the carrier when the carrier is in the stack aligning position such that the first aligning member is movable relative to a lateral edge portion of the carrier, and includes a first upright flat wall with a first abutment surface parallel to the lateral sides of the paperboard stack and a profile higher than the height of the stack. A first electrically driven positioning member is disposed to move the first aligning member when the carrier is in the stack aligning position between an extended position, where the first aligning member is proximate to the lateral edge portion, and a lateral outreach of the paperboard stack is set in accordance with a width of the stack, and a first retracted position where the first aligning member is distal to the lateral edge portion. A second aligning member includes a second upright flat wall having a second abutment surface in a transverse direction relative to the longitudinal direction and a profile higher than the height of the paperboard stack. The second aligning member is disposed adjacent to the carrier when the carrier is in the stack aligning position such that the second aligning member is proximate to a front edge portion of the carrier so that the second abutment surface defines a front outreach of the paperboard stack.
