Patent granted for a sheet processing apparatus with foreign object detection
A recently granted patent (Publication Number: US11767187B2) describes a sheet processing apparatus that includes a unique foreign object detection system. The apparatus consists of a plurality of coils positioned at the interface of the sheet processing apparatus, which is responsible for receiving and feeding the sheet into the transport path. These coils generate magnetic fields and are arranged to surround corresponding kicker rollers. The kicker rollers are designed to kick the sheet towards a gate for further processing.
The circuitry of the sheet processing apparatus is configured to determine the presence of a foreign object based on the differential values between the signals output from the coils. The coils, known as foreign object detection coils, output different signals depending on the proximity of a foreign object. By comparing the signals from the coils, the circuitry can determine whether a foreign object has entered the interface.
In one embodiment, the apparatus sets a reference value for each coil in advance. The circuitry then calculates the first differential values between the signals output from the coils and the reference values. It also calculates the second differential values between the first differential values for each coil. Based on these second differential values, the circuitry determines whether a foreign object has entered the interface.
The surfaces of the coils are parallel to the surface of the sheet, and they are arranged in a direction perpendicular to the direction in which the sheet is fed. The coils are equidistantly arranged from the space inside the interface where the sheet is stored. Adjacent coils may partly overlap, and they can generate opposite magnetic fields. The magnitudes of the magnetic fields generated by the coils are the same, and the shapes and numbers of turns of the coils are also the same.
In another embodiment, the sheet processing apparatus includes means for generating magnetic fields from the coils, means for calculating differential values between the signals output from the coils, and means for determining the presence of a foreign object based on these differential values. The arrangement of the coils surrounding the kicker rollers remains the same.
Overall, this patent describes a sheet processing apparatus with a unique foreign object detection system using coils and differential values. The system allows for efficient detection of foreign objects entering the interface, ensuring smooth and safe sheet processing.
