Optoelektronische Vorrichtung

Automatic control system of reflection type sensor in duplicate apparatus, operates optical emitter in stored operation current level, when added current level exceed start error current level

Optical intensity of light output by optical emitter (32) reaches threshold value, before the applied current level exceeding the start error current level, is determined. If the applied current level exceeds the start error current level before an error signal is transmitted and optical intensity reaches threshold value, then optical emitter is operated on the stored operation current level. The current level of the optical emitter corresponding to the operating condition is determined. The optical emitter current operation level is stored in memory. When difference exists between determined current level and stored current operation level, current is supplied to optical emitter so that the current level is more than the threshold level of photodetector. A comparator compares the added current level and the start error current level.

DOUBLE-FEED SHEET DETECTION APPARATUS

An apparatus for detecting double-feed of sheets has a light emitting source 1, such as an LED, and a light receiving sensor 2 located on opposite sides of a sheet transport path. Before the first sheet is fed, the gain of a variable gain amplifier 3, which amplifies an output of the sensor, is automatically adjusted so that an output level of the amplifier is set at a constant value. The intensity of the source 1 also is adjusted so that when a single sheet is fed the output is at an appropriately lower level. When the first sheet passes, an output level of the amplifier is measured and the level for a single sheet is stored. Each time a sheet is fed subsequently, the output level is measured and compared with the stored data to detect double-feed. Means are provided to increase the intensity of the source if signal output begins to decrease as single sheets are fed one by one, for example as a result of degradation of the sensor. ...

DOUBLE DETECTION SYSTEM

The present invention relates to an electro-optical system for double document detection wherein an improved calibration is employed. To calibrate the system, a microcontroller generates a series of increasingly wider pulses, which are transformed into a series of respective increasingly higher ramp pulses to drive a light emitter (LED, a laser diode or fiber optic coupled laser) at gradually increased power until the predetermined value of an output signal of the light detector (photo-transistor) is achieved. Then the pulse width corresponding to the predetermined value of the output signal is fixed. This width becomes the drive for the light emitter until another calibration changes it. The microcontroller (with the software in it) monitors the output signal to determine a double-feed document condition if the output signal exceeds a predetermined value. The system is capable of "hands-off" calibration. To detect a "true" double-feed document condition, a software timer counts a prolongation ...

Method and apparatus for detecting overlapping products in a singulated product stream

A singulated stream of products comprised of both single and overlapping products is transported through a scanning zone along a transport path. Each single or overlapping product defines a shadow on the transport path that is analyzed to determine the presence of product multiples in the product shadow by measuring the width and length of the product shadow. If the length of the product shadow exceeds by more than a predetermined amount the average length of previously measured shadows having a similar width, the shadow likely contains two or more overlapping products. As the product shadow moves through the scanning zone, each product included therein is scanned for affixed bar codes by a plurality of bar code scanners. If two different bar codes or two identical bar codes from mutually exclusive scanners are recorded for a single product shadow, then the shadow likely contains two or more overlapping products.

Method of making pressure sensitive adhesive tape rolls with a transparent to the core appearance

The method of the present invention provides a way to make rolls of high shear strength pressure sensitive adhesive tapes with a transparent to the core appearance in a relatively short time and without the need to subject the rolls to additional method steps. Moreover, the present invention achieves such transparent to the core appearance by sufficiently wetting-out the adhesive on the tape backing to remove microscopic air bubbles entrapped within the harder and less deformable high shear strength adhesive layers. The method comprises a rewinding method and is characterized by the use of a pack roll during rewinding to provide a sufficiently high contact pressure to the non-adhesive side of the tape substantially at the application point of the tape to the tape roll. In one aspect, a sufficient contact pressure is provided by the pack roll so that the pressure sensitive adhesive tape rolls are made with a transparent to the core appearance at the time of the rewinding step. In another aspect, the method further includes the step of aging the tape roll after the rewinding step is complete for allowing the tape roll to become transparent to the core after the rewinding step.

Device and method for controlling the tracking of a value document stack

In order to continuously separate value documents from a value document stack (10), the value document stack is lifted and tracked to the separator (30). In order to control the tracking of the value document stack, an image of one side of the value document stack is taken and evaluated in order to recognize the edges of the individual value documents. The tracking of the value document stack is controlled on the basis of the number of value document edges which are detected in the image taken. If, however, the number of value document edges cannot be detected or can be detected only insufficiently, a brightness of the image in this image portion is also determined. When separating the value documents shown in this image portion, the tracking of the value document stack is controlled on the basis of the brightness detected in this image portion.

The platen structure ensures reliable sheet material run-out by compensating for a reduction in sheet material weight as the final or last sheets of the stack are singulated/separated. Furthermore, the compliant coupling enables the various segments of the platen structure to conform to the contour of the stacked sheet material, i.e., a cantilevered delivery profile.
