Abstract
According to one embodiment, a separation and extraction apparatus includes an extraction unit, separation unit, air supply mechanism, detector, and controller. The extraction unit extracts and conveys one or more paper sheets from a stack of paper sheets. The separation unit separates one paper sheet from the other paper sheet(s) of the one or more paper sheets. The air supply mechanism supplies air toward a side surface of the stack. The detector detects a bundle state of the stack, which is related to a contact state between the paper sheets. The controller sets an extraction condition depending on the bundle state, which includes drive conditions for the extraction unit, separation unit, and air supply mechanism.
Claims7
A separation and extraction apparatus comprising:
- a support unit configured to support a stack of paper sheets stacked in a stacking direction, the stack having an upper surface, a lower surface, and a plurality of side surfaces extending in the stacking direction;
- an extraction unit configured to extract one or more paper sheets from the stack and convey the one or more paper sheets;
- a separation unit configured to separate one paper sheet from the other paper sheet or paper sheets of the one or more paper sheets;
- an air supply mechanism configured to supply air toward a first surface selected from the side surfaces;
- a detector configured to detect a bundle state of the stack, the bundle state being related to a contact state between the paper sheets;
- and
- a controller configured to set an extraction condition depending on the bundle state, the extraction condition including a drive condition for the extraction unit, a drive condition for the separation unit, and a drive condition for the air supply mechanism.
A bundle-state detection apparatus comprising:
- a support unit configured to support a stack of paper sheets stacked in a stacking direction t the stack having an upper surface, a lower surface, and a plurality of side surfaces extending in the stacking direction;
- a light emitting unit configured to emit a light beam toward a first surface selected from the upper surface and the lower surface;
- a detector arranged opposite to a second surface selected from the side surfaces, and configured to detect a plurality of light intensity distributions of transmitted beams emerging from a plurality of regions on the second surface to generate a plurality of detection signals, the transmitted beams being generated by the light beam which passes through the stack;
- and
- a processing unit configured to process the detection signals to detect a bundle state of the stack, the bundle state being related to a contact state between the paper sheets.
