A medium conveying apparatus includes a suctioner that suctions a medium of a plurality of media to a feed belt, a driver that moves the feed belt to feed the medium, a first side blower that blows air at a first airflow rate to a first end face of the medium, a second side blower that blows air at a second airflow rate to a second end face of the medium, and a controller that controls the first side blower to blow air to the first end face at a third airflow rate that is greater than the first airflow rate and the second airflow rate when the medium has not been auctioned to a first portion of the feed belt close to the first end face and has been auctioned to a second portion of the feed belt close to the second end face.

A mail processing system utilizes a conveyor to shingle or de-shingle mailpieces as they move through the processing system and utilizes belts to move the mailpieces. A first shingling conveyor moves a first mailpiece to overlap with a second mailpiece to create shingled mailpieces. A second shingling conveyor moves a first mailpiece away from a second mailpiece to de-shingle them to create singulated mailpieces. A camera takes images of the mailpieces in the conveyor and image analysis software is used to determine dimensional aspects of the mailpieces that are used to control the belt speeds to move mailpieces with respect to each other. A mail processing system may include a mail processing station that scans addresses, applies postage and/or weighs the mailpieces. Mail may be de-shingled prior to being weighed and then re-shingled for subsequent processing, or mail may be shingled prior to passing through a scale if weighing is not necessary.

Perforated endless conveying belts are stretched between drive and idle rollers. A suction box is arranged between upper and lower belt portions of the perforated endless conveying belts. Abutment members are attached to positions of a support corresponding to the perforated endless conveying belts and pressed against the perforated endless conveying belts. The upstream of the suction box from the abutment members forms an attracting area, and intake holes are formed therein. Lifting plates extend to at least an intake hole range of the attracting area between the perforated endless conveying belts. The lifting plates move between a first position to vertically open the intake holes and project from conveying surfaces of the perforated endless conveying belts and a second position to close the intake holes and retract from the conveying surfaces of the perforated endless conveying belts.

An article supporter for a supply device includes a feeder that supplies, by air suction, an uppermost thinly tabular article from a bundle of a plurality of thinly tabular articles that is stacked and is partially different in thickness, the article supporter for supporting the bundle with a gap between the uppermost thinly tabular article and the feeder, and the article supporter includes: a first support that supports respective thinner parts of the plurality of thinly tabular articles; a second support that supports respective thicker parts of the plurality of thinly tabular articles and is movable upward and downward; and an adjuster that adjusts a level of the second support such that the uppermost thinly tabular article of the bundle is set within a predetermined range in a vertical direction.

A sheet transport device includes a processor configured to adjust movement of a transport unit that transports a sheet on the basis of a transport load of the sheet.

A feeder includes a body, a mount portion disposed in the body to support from below part of recording media stacked thereon, a lift that raises the mount portion, a support portion connected to the body to support from below another part of the recording media while the mount portion is raised, the support portion being located higher than a position of a mount surface of the mount portion while the recording media are stacked on the mount portion, a blowing portion that blows air between the recording media stacked on the mount portion, and a transport portion that transports the recording media stacked on the mount portion.

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

A sheet transport device includes a processor configured to change lifting control for lifting sheets on a tray, which are to be floated up and handed over, from normal state control to small-quantity state control in a case where it is detected that the remaining number of sheets on the tray is small.
