    摘要: An image processing apparatus includes a transmitter, a receiver, a comparison circuit, and a control unit. The transmitter transmits an ultrasonic wave to a conveyance path through which a sheet is conveyed. The receiver faces the transmitter with the conveyance path in between, and receives the ultrasonic wave transmitted by the transmitter. The comparison circuit compares a level signal indicating a reception level of the ultrasonic wave received by the receiver with a threshold signal for determining whether or not the sheet is double-fed in the conveyance path, and outputs a comparison result signal according to the comparison result. The control unit determines whether or not there is a possibility of a defect in the double feed detection function of detecting double feed based on the comparison result signal and the level signal.

    摘要: The present disclosure provides embodiments of a lapper assembly for use to overlap successive sheets of wood veneer or other materials along a conveyor. The lapper assembly may include a stop member configured to be rotatably mounted to a roller such that the stop member is pivotable around the rotational axis of the roller independently of the rotational angle of the roller. The lapper assembly may further include a lever arm coupled to one end of the stop member. An actuator may be pivotably coupled to the lever arm and the conveyor frame, and operated to pivot the stop member between a workpiece engaging position, in which the stop member extends into the path of workpiece flow, and a workpiece disengaging position below the path. Optionally, the lapper assembly roller and other rollers upstream/downstream may be operatively connected to a drive. Corresponding systems and methods are also disclosed herein.

    摘要: The invention relates to an apparatus, in particular a roll cross cutter, for forming a shingled stream of underlapping or overlapping sheets, in particular paper or cardboard sheets, comprising a transport device for transporting sheets, a shingling device for underlapping or overlapping of the sheets at least in some regions, a braking device following the shingling device in the transport direction of the sheets for braking of shingled sheets, in particular by the formation of a brake gap for the passage of sheets brought together in a shingled manner, and a cross-cutting device upstream of the shingling device for cutting a material strip into individual sheets. According to the invention, an intake section is provided between the shingling device and the braking device for intake and further transport of a sheet, trailing in the shingled stream, into the braking device.
