  • Patent number: 6373013
    Abstract: An apparatus for sorting and distributing sheet-like items, such as postal matter. A feeder successively feeds the sheet-like items to a stacker which is positioned above the feeder and on which the sheet-like items are stacked in an upright position. Both the feeder and the stacker have a bottom surface. The bottom surface of the stacker is normally positioned at a first distance above the bottom surface of the feeder. A bottom surface opening mechanism is able to open the bottom surface of the stacker to permit sheet-like items stacked in the stacker to be transferred to the feeder. A bottom surface moving mechanism is able to move the bottom surface of the feeder unit and the bottom surface of the stacker unit toward each other so as to position the stacker bottom surface at a second distance above the feeder bottom surface, with the second distance being less than the first distance, and is able to return the bottom surfaces to a position in which they are spaced by the first distance.

  • Patent number: 6107589
    Abstract: A small-size apparatus for sorting sheets or the like can form a delivery route by repeating sorting operation and prevent an overflow of sheets or the like. To this end, auxiliary sorting compartments are provided in an accumulator in the sorting operation for the first time, and when an overflow occurs, the allocated sorting compartments are shifted each by one compartment to the side of the auxiliary sorting compartment. In the first-time sorting operation, destination codes and thicknesses are stored in memory, and by the destination codes and thicknesses stored, overflow is predicted, a plurality of sorting compartments are allocated. By this arrangement, the sheets or the like can be prevented from overflowing, so that those sheets or the like which are rejected need not be manually added afterwards, and the efficiency of the sorting work can be improved.

  • Patent number: 5990438
    Abstract: Apparatus for sorting and distributing sheet-like items, such as postal matter. A feeder successively feeds the sheet-like items with the front surfaces of all the items facing in the same direction. A stacker is positioned above the feeder for stacking the sheet-like items in an upright position. As the sheet-like items are conveyed from the feeder to the stacker, a selector activates either a first reader or a second reader to read address codes applied to the front surfaces or the back surfaces of the sheet-like items. The selector selects the one of the first reader and the second reader to be activated based on which of the front surfaces and the back surfaces of the sheet like items have address codes thereon.

  • Patent number: 5749473
    Abstract: Apparatus for sorting sheets or the like, in which mail distributed to a number of collection sections can be easily recycled to a feeder for sorting the mail in accordance with the delivery order. Stackers, in which mail is sorted in accordance with address codes, are provided on an upper portion of the feeder. By pulling out a bottom plate of the stackers, the mail in the stackers falls down into the feeder. The mail distributed once can be recycled to the feeder in a short period of time, thereby reducing the time for carrier route sequencing of the mail. The mail is conveyed in a path extending both above and below the feeder and the stackers, thereby reducing the area required for the apparatus.

  • Patent number: 5593044
    Abstract: An apparatus for sorting sheet-like items, in which the items, which are to be sorted to plural collecting sections, can be easily recycled to a feeder for sorting the items in multiple sorts in accordance with a desired sorting order or sequence. A stacker is provided on an upper portion of feeder. By pulling out a bottom plate of the stacker, the once sorted items in the stacker are caused to fall down into the feeder. The items can thus be rapidly recycled to the feeder for another sort, thereby reducing the time required for complete sorting or sequencing of the mail.

  • Patent number: 5478992
    Abstract: When sheets are taken into a machine or discharged from the machine, characteristics of these sheets such as letters or symbols of these sheets are read by a sheet characteristics reading unit. A result of reading the characteristics is stored in a storage unit. When characteristics of a sheet are not able to be read at the time of accommodating sheets, this sheet is returned and only sheets of which characteristics have been able to be read are taken into the machine. Sheets of which characteristics are not able to be read at the time of discharging sheets are specified by a unit for specifying sheets of which characteristics can not be read. By this arrangement, each sheet in the machine is always managed.
