摘要： A method apparatus for determining the length of a roll of sheet material, including a side surface at which the edge of each of the plurality of layers of sheet material is exposed wherein the side surface of the roll of sheet material is exposed to a source of radiation and the radiation reflected from the edges of the roll is scanned in a radial direction to establish a first signal indicative of the reflected radiation and the number of edges of layers of sheet material. The length of the roll of sheet material is calculated using the sensed number of layers of sheet material in the roll. The method and apparatus are similarly adapted to determine the number of layers of sheet material in a stack of sheet material.

摘要： A counting device for counting the number of objects such as folded box blanks in a flow of folded box blanks characterized by a sensor having a portion engaging a leading edge of a blank in the flow and being moved to activate a pulse generating device. The device also includes an arrangement to lift the portion of the sensor out of engagement after the pulse has been generated to enable resetting the pulse generator and engaging the next following object of the flow.

摘要： An apparatus for counting the sheets of a stream of partly overlapping sheets wherein the leaders of the next-following sheets normally rest on the trailing ends of the preceding sheets has a transporting unit which defines a path having two mutually inclined portions with the second portion sloping downwardly at an angle of 15 to 90 degrees relative to the first portion so that the leaders of successive sheets are lifted off the trailing ends of the respective preceding sheets. A photocell generates signals on detection of successive leaders while the leaders are on their way from the first into the second portion of the path, i.e., while the leaders are separated from the trailing ends of the preceding sheets, and such signals are transmitted to a counter which regulates the conversion of sheets into a series of stacks containing preselected numbers of superimposed sheets. The photocell is installed substantially midway between the longitudinal marginal portions of the stream. The sheets which travel past the photocell are subjected to the deforming action of an endless belt or chain which causes the upper sides of the sheets to assume a concave shape with the deepmost portion of each sheet extending in parallelism with the direction of transport of the stream.

摘要： The disclosure relates to an air pressure sensor comprising a first air passage, a branch passage having an opening into the air passage, a sensor in the branch passage responsive to variation in air pressure in the opening and jet means for air flow through the first passage adjacent the opening to the branch passage to create an increased depression in static pressure as compared with the remainder of the air passage to enhance the response of the pressure sensor in the branch passage when air flow through the first passage occurs. The air passage terminates in a probe having an orifice to be opened and closed by the absence of and presence of a surface in contact with the probe so that the pressure sensor indicates whether or not the probe is in contact with the surface. The arrangement is particularly suitable for counting a "shingled" stream of sheets such as signatures, the stream passing the orifice to the probe such that the orifice is opened and closed as successive sheets pass the probe, the resulting signal in the air pressure sensor being used to operate a counting device.

摘要： A system for counting overlapped newspapers delivered to a stacker which employs an optical sensor which is passive in nature. Accurate count is obtained by image analysis of the image presented by the edge of the newspaper flow as the image is focused on a linear CCD array. Definitive values are determined which are quantitative of the top profile, height, of the newspapers. The processing technique employed determines the rate of change of the height of the image and utilizes the rate of change data to output a newspaper count increment when the rate of change, derivative, of top profile height changes from a positive value to a negative value and the measured profile height exceeds a calibrated value thickness, and outputs two newspaper count increments when the measured profile height exceeds a second calibrated value thickness.
