    Abstract: A method and apparatus is disclosed for reading and decoding information extracted from a form. In the system of the present invention, packages are randomly placed on a conveyor belt, with their labels facing a two-camera subassembly. As the conveyor belt moves, the two-camera subassembly continuously takes images of the belt underneath the overhead camera. The design of the camera permits it to take a high resolution image of a non-singulated, unjustified package flow. A digital image of the packages within the field of view of the camera is then transferred to the processing system for analysis. The processing system identifies individual packages in the image, extracts them and then analyzes the information written on the package labels. The analysis process utilizes conventional Optical Character Recognition (OCR) and Intelligent Character Recognition (ICR) techniques to evaluate the information written on the package label.

  • Patent number: 4550820
    Abstract: Apparatus for orienting and stacking hollow, frusto-conical containers or other articles has a downwardly inclined ramp for receiving the articles in random orientations. A deflector wall spaced by a gap from the bottom end of the ramp serves to deflect the articles to the gap, which is greater than the width of the widest end of the articles and less than the length of the articles, so that the articles can drop into the gap only with the widest end uppermost. Endless conveyor belts are provided below the gap for receiving the articles therebetween and conveying the articles. The ramp is formed by the upperwardly driven upper run of an endless belt arrangement, or has an upwardly rotating roller at the bottom thereof, for displacing upwardly of the ramp an adjacent portion of any of the articles which bridges the gap so that the containers are caused to fall properly into the gap.

  • Patent number: 4436226
    Abstract: A metering device for particulate material in which backups and caking of material is inhibited by the provision of a "live" metering gate consisting of an upper blocking section and a lower material contacting surface. The lower surface is continually moved in the direction of material flow at a speed approximately equal to or slightly greater than the material flow speed. An elongate rotatable rod carried at the lower end of a blocking plate preferably provides the material contacting surface.The gate is vertically adjustable so that the volumetric flow rate of material can be controlled. In a preferred embodiment the gate is located above the end of the material bearing surface and is adjustable along an axis which diverges from vertical by an appreciable angle, preferably about 45.degree..The transverse dimension of metered material is also controlled by means of two blocking members which extend inwardly toward each other from behind the gate.

  • Patent number: 4379504
    Abstract: The feeding device comprises a horizontal circular singling disc, which rotates continuously or intermittently and has a peripheral crown of recesses acting as article receiving pockets. The surface of the singling disc is subdivided into a first, larger article-receiving portion acting as feed reservoir for the articles which are fed at random thereinto, delimited by a fixed circumferential side wall extending over a circumferential arc around the periphery of the singling disc, and by a fixed partition wall extending across the surface of the singling disc, and into a second smaller article-delivery portion lying outside of the feed reservoir. At the interior of the feed reservoir there is mounted a distributor dish having the shape of an asymmetrical flat or truncated cone. The distributor dish is cased to perform rotary oscillations parallel to the surface of the singling disc, about an axis which coincides with the axis of rotation of the singling disc.

  • Patent number: 4271953
    Abstract: An automatic feeding hopper employs a reservoir for storing disk-like objects in a plurality of substantially horizontal rows in a substantially vertical plane. A conveyor adjoins the reservoir for engagement with a substantial portion of the lowermost row of disk-like objects in the reservoir to remove the disk-like objects from the reservoir, an exit chute is positioned adjacent the conveyor to receive the disk-like objects in a single row, and a deflecting member is positioned near the entrance to the exit chute to guide and maintain the flow of disk-like objects in a single row from the conveyor into the exit chute. The deflecting member has an upper concavely curved surface intersected by a lower curved surface which leads into a side of the exit chute, the curved surfaces meeting at an edge located a distance above the surface of the conveyor slightly more than the diameter of a disk-like object.

  • Patent number: 4185732
    Abstract: Ampuls are processed through a plurality of workstations successively arranged along a path in an ampul processing machine. At one station, an anti-jammer device is operative for preventing ampuls being guided through a continuously converging infeed chute from jamming and blocking the path. An intermittently-driven chain conveyor advances ampuls along the path during advancement time periods in which the ampuls are conveyed from one station to the next, and maintains the conveyed ampuls within their respective stations for processing, i.e., filling or sealing, the ampuls during dwell time periods which alternate with the advancement time periods. At another station, a movable infeed shuttle is operative for feeding ampuls to the chain conveyor during each dwell time period. At still another station, a movable outfeed shuttle is operative for discharging ampuls from the chain conveyor during each dwell time period.

  • Patent number: 4119024
    Abstract: A conveyor carries cans or other refuse from a source of cans to a jaw crusher. The conveyor is adapted to drop cans generally one at a time into a bin, and the bin has an opening to release each can when the jaws open to receive it. In the open position, the jaws are spread far enough apart so that the can drops to the bottom thereof. A flap is provided at the bottom to hold the can between the jaws. The end of the flap extends to a position above the bottom of the stationary jaw. As the jaws come together in crushing, the moving jaw cams the flap downward along the stationary jaw. However, the flap is not cammed entirely out of the area beneath the jaw until the jaws have come together to hold the can. The flap ensures that no lip is formed on the can. After the jaws close, the flap is moved out from beneath the jaws so that when the jaws open, the crushed object can fall out of the jaws for carrying away.

  • Patent number: 4014460
    Abstract: In a spike orienting and positioning system, kegs of spikes are discharged onto a spike receiving surface. The spikes on the spike receiving surface are engaged by fingers which are first extended from and then retracted into a rotating drum whereby individual spikes are lifted from the spike receiving surface and then dropped. This causes the spikes to enter slots formed in the spike receiving surface in a shank down orientation. The spikes are normally prevented from passing through the slots by tires which engage the lowermost spikes in the slots and which are selectively rotated to discharge individual spikes. The discharged spikes are guided into helical funnels which function to rotate the spikes into predetermined orientations. The oriented spikes then enter chutes wherein they are temporarily retained by escapement mechanisms. Upon release by the escapement mechanisms, the spikes travel through the chutes into position for insertion.
