  • Patent number: 6092803
    Abstract: The impact sound when a sheet member forms a loop is reduced so as to make the apparatus less noisy. A speed control device is provided for making the transport speed when the sheet member is made to hit a first transport device by a second transport device relatively slower than that of the first transport device. By changing the amount of transport of the first transport device along the width of the sheet member at right angles to the transport direction of the sheet member, the loop is formed successively along the width of the sheet member.

  • Patent number: 6005211
    Abstract: An efficient package sorting system in which a stationary matrix of multi-directional conveyor cells sorts packages to a plurality of destination locations. In a preferred embodiment, the matrix delivers sorted packages to a plurality of lift assemblies that further transfer the packages to receiving conveyors or chutes on different levels. According to another preferred aspect of the system, a selectively elevating stop bar is provided to control side transfer between conveyor cells. A controller is operative to plan a path for each of the objects from the input cell to a destination location, to monitor availability of successive conveyor cells along the path, and to cause an object to be moved to the next conveyor cell along its path only when the next conveyor cell is available. The system may include a plurality of sensors positioned to sense the passage of objects from one conveyor cell to another, the sensors being connected to the controller.

  • Patent number: 5971388
    Abstract: An automatic original document feeding device which can shorten a length of time required for refeeding sheets of the original document after a jamming of a sheet of the original document is cleared. When a trouble signal is received indicating that a sheet of the original document remains within a feed path due to an improper feeding or a jamming before the sheet is completely scanned, a side cover is opened and at the same time a driving mechanism is actuated for automatically lowering the sheets of the original document from a feeding position. If the jamming occurs at a later position in the paper path after the image has been completely scanned, the side cover does not have to be opened, the driving mechanism is not lowered, and the sheets of the original document remain in their feeding position.

  • Patent number: 5954206
    Abstract: An optical inspection system inspect products passed through an inspection region. Light is directed onto the products form optical control units including light emitting diodes. Light emitted from the diodes is directed by cylindrical lenses onto the products at a specified target region, and a sensor detects light reflected from the products. Focussing is achieved by an outer row of the diodes being displaced outwardly relative to axes of respectively cylindrical lenses, so that light originating from the outer rows of diodes converges towards that passing along a central axis extending from a central row of the diodes through a central lens to the target region, light from all rows of the diodes being therefore focussed substantially at the target region.

  • Patent number: 5954207
    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 accumulating means 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 15 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: 5954330
    Abstract: An apparatus and method of synchronizing entry of a mailpiece from a mail feeder into a designated mailpiece location of a mail sorting conveyor. The method includes the steps of establishing a symmetric speed versus time profile around a send signal. In a first case, when the mailpiece stops before receiving the send signal, the method further includes following the speed versus time profile to accelerate to a merge speed for merging the mailpiece with the designated mail location of the sorting conveyor. In a second case, when the send signal arrives before the mailpiece reaches the stop position, holding the mailpiece at a constant speed across the speed versus time profile until the position of the mailpiece intersects an opposing side of the speed versus time profile and then following the speed versus time profile to accelerate the mailpiece to a merge speed for merging the mailpiece within the designated mail location of the sorting conveyor.

  • Patent number: 5951002
    Abstract: A sheet supplying apparatus includes a stacker on which a plurality of sheets can be stacked as a sheet stack, a supply system for supplying the sheet on the stacker, and an adjusting system for adjusting a supplying force of the supply system in response to a shifted amount of the stacker. The stacker may be shifted dependent on a weight of the sheet stack, but independent of the thickness of the sheet stacker. Alternatively, the stacker may be shiftable in a stacking direction in response to sheet size and weight. The adjusting system may adjust the supplying force irrespective of the size of the sheets.

  • Patent number: 5947461
    Abstract: The present invention relates to an input system for feeding one-up sheets from a paper web to a high speed mass mailing inserter system. The input system includes a feeding module for supplying a paper web having two web portions in side-by-side relationship. A merging module is located downstream in the path of travel from the feeding module and is operational to feed the two web portions in an upper-lower relationship so as to reorient the paper web from the side-by-side relationship to an upper-lower relationship. A separating module is located downstream in the path of travel from the merging module and is operational to receive the paper web in the upper-lower relationship and separate the paper web into individual two-up sheets. In order to separate the two-up sheets into one-up sheets, a stacking module is located downstream in the path of travel from the separating module and is configured to receive the two-up sheets, stack the two-up sheets and individually feed one-up sheets from the stack.

  • Patent number: 5938188
    Abstract: A sheet feeding apparatus has a sheet container which contains sheets and is removably mounted to a main body of the sheet feeding apparatus, a separation device including a conveyer and a separation member are urged against the conveyer with a predetermined separating pressure to separate the sheets fed out from the sheet container one by one, and a pressure increasing unit for increasing contact pressure between the conveyer and the separation device above the predetermined separating pressure. The pressure increasing unit increases the contact pressure until the mounting of the sheet container to the body of the sheet feeding apparatus is completed so that, even if the sheet container is inserted into the sheet feeding apparatus vigorously, the sheets are prevented from entering between the conveyer and the separation member, thus preventing poor sheet separation.

  • Patent number: 5934477
    Abstract: An apparatus for separating a mixed granular material into granules of different specific gravities or ranges of specific gravity using a powered air flow is described. A divider plate is located below the air flow path within the apparatus to separate the two material flows from each other. The divider plate can be rotated about an axis and can also be translated or displaced within the apparatus in order to precisely define the separation point between the material flows. Hoppers are used to collect and discharge the separated granular materials, and a conveyor belt is provided within the apparatus to transport one of the separated granular materials to the corresponding hopper. The conveyor belt reduces clogging of the separated granular material and also allows a greater degree of separation to be maintained between the hoppers, thereby allowing standard conveyors to be placed beneath the hopper discharge openings.
