  • Patent number: 4869813
    Abstract: Apparatus for inspecting and sorting drills oriented in the same direction in a hopper assembly. The hopper assembly feeds the drills, one at a time, and places them in a predetermined ready location. A camera, part of the inspection assembly, mounted directly over the predetermined ready location, takes preliminary measurements and alerts the system controller that a drill is available for a high resolution second inspection for wear and then for sorting. A robot assembly then picks up the drill from the ready location and orients it in front of two high resolution cameras, also part of the inspection assembly, for a visual inspection for wear. A control assembly then analyzes the results of the inspection and determines the drill size and whether or not it needs to be re-ground. The robot assembly then sorts the drill into an appropriate predetermined bin within a bin assembly as a function of size and wear. The process is then repeated.

  • Patent number: 4778060
    Abstract: An apparatus for sorting tires according to an alphanumeric code printed directly on the tread surface of each tire. Green (uncured) tires are supplied on a feed conveyor, single file, to a receiving station of a tire painting machine (tire painter), and each is elevated, then indexed to a painting station (booth) where the green tire is to be painted, inside and outside, before it is taken to a curing press. While in the elevated position in the booth, the code is optically read by a line-scan camera system, before the tire is painted. The information read is stored and processed by a microprocessor after it locates the code which determines how the tire is to be sorted, and disregards another production code not pertinent to the task at hand. A first programmable controller (PC) locates the horizontal center line of the tire, indexes to the next of three station in the painter on cue, and imparts rotation to the tire so that the camera system can perform its functions.

  • Patent number: 4567988
    Abstract: In a system for conveying objects bearing indicia of destination addresses to associated receptacles, the indicium on each object is converted to an address code identifying a particular receptacle, and the code is fed to a control device for storage. The objects are then moved sequentially past a meter which reads and feeds their indicia to the control device and counts the objects as they pass on to a succession of uniformly spaced containers traveling in a continuous, closed path near the receptacles. All objects passing the meter thus become associated with respective containers, and their number equals the number of containers sequentially passing an arbitrary metering point along the closed path. Any container carrying an object reaches a point over its target receptacle when the meter count for that object corresponds to the indicium/address code which associates that object with that receptacle.

  • Patent number: 4503976
    Abstract: An improved envelope tracking and control system for a mail sorting machine of the type which reads a sorting code imprinted on each envelope and deposits the envelope in the proper sorting bin by deflecting a diverter gate associated with the bin. Each diverter mechanism has two sets of photo sensors which sense the presence of an approaching envelope. Tracking circuitry processes the sort code obtained from the envelope and transfers the processed data to the tracking circuit for the next diverter if the data does not coincide with a code that has been preassigned to the diverter. The processed data is held in a latch circuit and is passed on only if the envelope is sensed by the second set of photo sensors. If there is coincidence of the data, a one shot pulse applied to a solenoid deflects the appropriate gate for a predetermined time period that avoids possible damage to the solenoid or to the circuit components.

When a circuit receives a signal corresponding to the coded designation for one of its associated gates, that gate is operated to deflect the envelope into an appropriate bin.

  • Patent number: 4369886
    Abstract: An infrared light generator directs a flashing band of light across a conveyor belt carrying randomly spaced materials having differing properties. The frequency of the flashing band sequentially alternates between two infrared frequencies chosen for their peculiar reflectivity characteristics. Infrared light sensitive cells detect energy reflected from the passing materials as they are exposed to the infrared light. Comparator circuitry examines the detected information, determining the size and material nature of the passing pieces. Powered paddles act at the direction of the comparator, physically separating variously sized inorganic from organic materials, or ripe from unripe comestibles, to cite examples.

  • Patent number: 4344539
    Abstract: A sorting apparatus universally applicable to any article sorting task without the necessity of changing a background member for each article type is characterized by first and second optically imposed "backgrounds" against which light reflected from the same portion of each article passing within a predetermined viewed area as defined by an optical frame is detected. Photodetectors associated with each "background" are operative to generate first and second electrical signal representations of the reflected light detected against each background. An electrical signal representative of the portion of the viewed area occupied by the article and functionally related to the difference between first and second signal representations is used to scale one of the first or second signals to provide a signal representation of the full-frame percentage reflectivity of the article. Additionally, a nulling circuit is operative while the articles are passing through the viewer to provide drift compensation.

  • Patent number: 4339044
    Abstract: The installation comprises several inspecting devices disposed along a track and controlling a switch. Each inspecting device is followed by a device for detecting the passage of the sheets, associated with a cyclic counter assigning a consecutive number to each sheet. A logic circuit directs the information from the inspection devices to reference memories the number of which is equal to the number of possible content conditions of the counters, (i.e. consecutive numbers) the information being directed to the reference memory whereof the number corresponds to the consecutive number of the sheet as assigned by the counters. Since the sheets are assigned numbers during their passage through the inspection region, it is possible to have several sheets simultaneously in this region.
