  • Patent number: 4895359
    Abstract: A paper sheet counter is provided in which a large number of paper sheets stacked in a hopper are fed one by one between a pay-out roll and separating rolls, and stacked in a stacker. According to the invention, the separating rolls have separating roll shafts angled slightly relative to a plane perpendicular to the axis of the pay-out roll.

  • Patent number: 4627828
    Abstract: A toothed drive belt having inner and outer reinforcing fabric layers. The inner layer has a large mesh size, is highly stretchable, has a fine warp of 30 to 210 d, has a normal weft, and the sum of the cover factors of the warp and weft are no more than 20. The inner layer may have either a flat or a wavy shape within the teeth. The outer layer has a low stretchability and a normal warp and weft. The inner layer, which is bonded strongly to the rubber substrate of the belt due to its large mesh size, easily follows the deformations of the teeth. Due to a small thread size, the amount of PLD is reduced.

  • Patent number: 4583726
    Abstract: A sheet transfer apparatus is for a sheet counting apparatus in which paper sheets stored in a hopper in a stacked state are fed by a payout roll from the hopper to a stacker at the downstream side of the payout roll. A guide assembly is disposed opposite to the periphery of the payout roll and is adapted to separately guide the paper sheets from the hopper toward the stacker in cooperation with the payout roll. According to the invention, the guide assembly, which has a frame member carrying a separating roll, a pinch roll and a guide plate, is pivotally mounted so as to be movable between a closed position in which it is close to the periphery of the feed-out roll and an opened position in which it is farther away from such roll. The position of the frame member is controlled by a pivotable opening/closing device engageable with the frame member for selectively holding the frame member in the closed position or the opened position.

  • Patent number: 4560154
    Abstract: In apparatus for counting the number of the paper sheets in which paper sheets are fed-out from the inside of the hopper by a feed-out roll assembly and are extracted from the feed-out roll assembly by extracting rolls operating at a speed faster than the speed of the feed-out assembly, the feed-out roll assembly comprises a pair of first payout rolls having a frictional surface and a slippery surface on their peripheries and a second payout roll intermediate the first payout rolls which has a frictional surface on its entire periphery. The rolls are mounted on a driving shaft, and at least the second payout roll is connected to the driving shaft through an overrunning clutch. When the trailing end of the paper sheet being removed from the hopper is in contact with the slippery surfaces of the first payout rolls, the sheet is extracted by the extracting rolls at a constant speed equal to the speed of the extracting rolls and thus, without being affected by the peripheral speed of the feed-out roll assembly.

  • Patent number: 4514856
    Abstract: An apparatus for counting the number of paper sheets is described in which a target number entered by an entry unit is stored in a target number memory and displayed in a target number display section, the count number supplied from a sensor and counter section since the time of start of counting is displayed in a count number display section and compared to said target number, and the counting number is discontinued in case of coincidence between said count number and the target number. According to the invention, the entry section has a batch key, a plus key and a minus key. A gross or an approximate number is entered by the batch key and incremented or decremented by the plus or minus key for adjustment of the gross number to the desired number. When the gross number is the infinite number, a continuous counting operation is performed until depletion of the paper sheets.
