A paper feeder for transporting paper sheets, includes: a head fan that blows air on the paper sheets; a suction fan that applies negative pressure to the paper sheets blown by the head fan; a switching member that changes the direction of the air from the head fan; a head shutter that blocks the flow of the air directed by the switching member; and a hardware processor that determines the blocking time of the airflow, wherein the switching member changes the air direction between a first direction for floating the paper sheets and a second direction toward the suction fan, and the hardware processor determines stop timing of the air blow in the second direction directed by the switching member as the start timing of clocking the blocking time of the airflow, based on the weight and the resistance to an external force of the paper sheets.

A sheet feeder device includes: a sheet feed tray configured to store a sheet stack formed with a plurality of paper sheets; an elastic member capable of expanding and contracting; a contact mechanism configured to bring the elastic member into contact with an edge of the sheet stack; an expansion mechanism configured to expand the elastic member in a direction of stacking of the paper sheets; and a control unit configured to cause the expansion mechanism to expand the elastic member while the elastic member is kept in contact with the edge of the sheet stack by the contact mechanism.

A corrugated paperboard sheet feeding apparatus comprises: a plurality of sheet feeding rollers; a grate formed with a plurality of opening portions for receiving the sheet feeding rollers and configured to switch between contact and non-contact states of the corrugated paperboard sheet with respect to the sheet feeding rollers; and a suction box configured to suck the corrugated paperboard sheet downwardly by gaps between the sheet feeding rollers and the opening portions, wherein each of the gaps is formed to be 10 mm or less, and wherein the apparatus further comprises a mat switch for detecting an entry of a person into an area in a sheet feeding section, and a control device for stopping movement of the sheet feeding rollers and/or the grate when the mat switch is turned on.

A pharmaceutical filling system for a high volume pharmacy is described. The system can include a paper feed device and method. The system may include a paper collator with at one selectively openable shelf. A control device may monitor the capacity of the selectively openable shelf, and instruct a printer to hold printing additional print jobs. The selectively openable shelf may then be opened to allow the printed literature resting thereon to fall to a lower shelf, and the printer can then be restarted. Sheets of printed literature may be drawn from the paper collator, collected with any other sheets of printed literature associated with a prescription order, and mated with the prescription order for shipment.

The present invention relates to a feeder module for discharging sheets into a converting machine. The feeder module comprises a movable discharge conveyor comprising a plurality of belt conveyors which are configured to move between a discharge position (DP) in which the belt conveyors are contacting the lowermost positioned sheet in the stack and discharges said sheet, and a clearing position (CP) in which the conveyor belts are located underneath the loading surface.
