Abstract: A valve device is disclosed for controlling the delivery of gas from a pressurised source suitable for use in a pneumatic ejector in particle sorting apparatus. It uses a diaphragm as a valve member disposed over an output port from a chamber which is in substantially continuous communication with a source of gas or air under pressure. Both sides of the diaphragm are exposed to pressurised gas or air in the chamber. For this reason, and because the diaphragm itself engages the output port to close it, when the input pressure is applied there is a differential pressure which elastically deforms the diaphragm to close the output port. The diaphragm has a piezoelectric element, and the valve device includes an electric circuit operable to selectively activate the piezoelectric element and withdraw the valve member from the output port to admit pressurised gas or air thereinto.

Abstract: The invention relates to a process which enables foreign bodies to be rapidly recognized and filtered out of fibre processing lines. A stream of fibres is inspected by color sensors.

Devices controlled by the sensor device remove single pieces at discharge stations dependent on the sensed properties of the pieces.

Abstract: A plastic container sorter (10) moves labeled plastic containers (14, 20, 48, 54, 58) of various colors and transparencies through an inspection zone (18). A pair of line-scanning color cameras (22, 24) capture respective transmittance and reflectance images of the containers and generate raw transmittance and reflectance image data. The raw container data are digitized, normalized, and binarized to provide accurate transmittance and reflectance container RGB image data and binarized image data for differentiating container image data from background data. Container sorting entails eroding (120) the binarized transmittance image and merging (122) the eroded image with the transmittance image data to yield a transmittance image. The eroded transmittance image is analyzed (124, 126) to determine whether the container is opaque. If the container is opaque, color analysis proceeds by analyzing the reflectance image data.

Abstract: The separation device includes a container having a dome-shaped base and a peripheral wall surrounding the base to define a chamber for receiving a random mixture of defective and nondefective articles. A spiral-shaped ramp on the peripheral wall which surrounds the chamber and overhangs the base, leads to an elevated outlet opening. A vibrating device vibrates the chamber to excite movement of the defective and nondefective articles along the base and onto and up the ramp toward the outlet opening. The container also includes trap openings in the base and ramp to eliminate defective articles from the chamber. Discriminating devices are provided on the ramp that cause defective material to fall from the ramp back onto the base of the chamber. Only the nondefective articles can move on the ramp past the trapping devices toward the outlet of the container for transfer to another processing station.

Abstract: A glass cullet separator utilizes a multi-element optical sensor to detect when an opaque particle in a group primarily composed of transparent particles moving along a plane passes a first line lying in that plane, and the particular location of the particle along the first line. A signal from the optical sensor is fed to a microprocessor. After a delay equal to the time it takes for a particle to pass between the first line and a second line, which is parallel to and separated from the first line, the microprocessor causes a valve to open and emit a jet of high velocity air from a nozzle aimed toward the plane along the second line. The jet of air blows the opaque particle out of the plane where it is captured and separated from the remainder of the particles. A plurality of nozzles are located in a manifold which extends across the extent of the second line. The manifold also supports the valves and fluid conduits that interconnect the valves and the nozzles.

Abstract: A passively vented rejected article chute (40) includes at least two vents (44, 45) extending downwardly into the chute to vent air in directions (50) safely away from sorting and conveying functions, thereby improving sorting effectiveness. Rejected articles (14) that include defects (24) are deflected by an air ejector module (30) into the vented chute and are directed downwardly past the vents to preventing the vents from being blocked. The vents, formed by panels (46, 48), are flared open at their outer ends (54, 56) to decrease the velocity of exhaust air as it passes upwardly through them. Reducing the exhaust air velocity allows small and/or light weight articles entrained in the exhaust air to fall back into the reject chute, thereby preventing spillage of the entrained articles.

Abstract: A sorter for sorting transversely-spaced articles moving along a direction of travel employs an array of fluid nozzles aligned transversely to the direction of travel for separating some of the articles from others, according to differences in their physical characteristics, by selectively directing respective streams of fluid toward some of the articles to deflect them from the direction of travel. The nozzles are arranged in a substantially linear transverse alignment relative to the direction of travel, each nozzle being connected to a respective selectively operable fluid supply valve. The valves are arranged in a nonlinear array in a common plane extending generally in the direction of alignment of the nozzles, and are connected to the respective nozzles by flexible tubes of equal length which interface the nonlinear array of valves with the linear transverse array of nozzles. The tubes are embedded in a hardened polymeric material which also forms the nozzles.

Abstract: The instant invention provides an apparatus and method for reliably separating a selected sheet from a spaced array of sheets transported on a conveyor. The invention continuously maintains vacuum on the conveyors, and uses selectively activated jets directed at the underside of the sheets to divert them for separating. The invention positively controls the destination of discrete, flexible sheets, such as photographic film, by continuously engaging the sheets with another conveyor during separating, sorting, shuffling or the like, as they travel in an array along a conveyor. Positive control of the sheets permits reliable, high speed separating of lightweight, flexible sheets.

Abstract: Seeds are sorted according to color by placing the seeds in uniform rows of indentations in a rotating drum and passing the seeds beneath a digital/imaging camera and strobe lights which create images of the seeds. The images are fed to a computer, which also receives information from a drum speed sensor.

Rejected seeds are fed into a reject hopper, and the selected or good seeds remaining in the drum indentations fall from the drum into another hopper.

Abstract: Plain or filter cigarettes are tested at a first station by two or more testing devices each of which monitors the cigarettes for the presence or absence of a particular defect. The testing devices generate defect signals which are delayed by shift registers so as to ensure that the delayed defect signals are transmitted to a segregating mechanism which removes defective cigarettes from a path that is common to the satisfactory and defective cigarettes and delivers defective cigarettes to selected receptacles which are installed at a second station and each of which gathers only cigarettes exhibiting a particular defect. Actuation of a switch entails the removal of a selected number of samples from the common path for satisfactory and defective cigarettes, and such samples are gathered in an additional receptacle at the second station.

Abstract: A gate station incorporates air pressure flows to direct clips in a production stream through the station and to selectively divert defective clips into a separate reject steam. Mounted on a support plate in the station are an upstream manifold, continuously supplied with low pressure air, and a downstream manifold, having a plurality of downwardly directed air ports and selectively supplied with high pressure air. Air flow from the upstream manifold is directed laterally over the upper surface of a clip so as to enable atmospheric pressure to maintain the clip travelling through the gate station in the production stream. If a clip is to be diverted, the downstream manifold is injected with high pressure air causing blasts of high velocity air through the downwardly directed ports. This high velocity air disrupts the flow from the upstream manifold and forces the leading edge of the defective clip downwards, pressing the clip into the reject stream.
