A food handling conveyor apparatus includes a sound detection system for detecting the presence of a foreign object, such as a stone, among food product being conveyed. The apparatus includes a generally elongated vibratory conveyor bed along which food products are conveyed, with at least one discharge gate positioned at one end of the conveyor bed. An actuator is operatively connected to the discharge gate for effecting movement thereof between closed and open positions. A sound detection system of the apparatus, preferably including one or more directional microphones, is positioned in operative association with the conveyor bed and functions to differentiate between the sound of food product being conveyed, and the sound of a foreign object. The sound detection system is operatively connected with the actuator for the discharge gate, and effects opening of the discharge gate in timed relationship to detection of a foreign object so that the object is moved out of the food product stream.

There is provided a microcontroller for controlling the activation of a hopper, bowl feeder, and linear feeder. There is further provided a blown fuse circuit which indicates that a fuse has blown for the various components of the part feeder system as well as preventing machines at the load from being powered should the fuse blow.

In an article handling system that functions to make article discrimination-identification determinations, the possible article orientations A, B, C . . . are stored and compared to establish maximum pixel difference numbers and identification of longitudinal window position along the article where such maximum difference occurs. Each of the possible orientations is compared with all other possible orientations so that a small number of windows is identified as part of a setting procedure. When operating, the work articles are scanned and only the data at window locations are used to make article orientation identifications to reduce time and memory requirements for data processing.

A bulk material handling conveyor system having a set of buckets carried in a continuous manner from an infeed zone where the buckets are filled with product by way of a metering vibratory feeder to an unloading zone and back to the infeed zone. The buckets may be selectively at least partially emptied in the unloading zone. The conveyor system also includes a proximity trigger for sensing the bucket at the infeed zone adjacent the metering vibratory feeder, a processing unit electrically connected to the proximity trigger for receiving and storing the output of the proximity trigger, a fill determining sensor mounted proximate the buckets between the infeed and unloading zones, the fill determining sensor being connected to the processing unit so that the processor receives and stores the fill status of the buckets upstream of the infeed zone, and a feeder control for cycling the metering vibratory feeder on and off responsive to signals from the processor, the processor signaling the feeder control to cycle on when a bucket is sensed by the fill determining sensor to be less than full.

A high resolution article handling system serves as an article discriminator or identifier by creating an object silhouette. The objects are singulated on a conveyor and scanned by a linear array of CCD units (2048 pixels per inch) at a scan rate of 10 MHz. Pixel transitions corresponding to object edge points are converted to a single count value from a counter which is synchronized with the scanner. A microprocessor with a first in, first out buffer memory needs only a capacity to handle the count value rather than all data from the pixels. Article orientation is corrected in response to signal generated by determining the count value difference between a reference value and a work article value at only the scan slice windows at equally spaced positions along the article length where differences have been predetermined to be a maximum.

High resolution parts handling system

A method for processing compacted data without converting the data into uncompacted form. A first set of digital data is converted into compact form by recording a set of points at which the signal level changes. A second set of digital data is likewise converted into compact form by recording the points of signal level change. A logic function is then used to compare the first set of compact data with the second set of compact data.

High resolution camera with hardware data compaction

A high-resolution vision system for a detailed inspection of parts. A charge coupled device provides high-resolution in both an X and a Y axis. Data from the charge coupled device resulting from a standard part is stored in compact form. Compact data from a part being inspected is compared with the compact data from the standard part to determine if the tested part is good or not.
