Abstract:
Apparatus for discriminately treating containers and the like, the apparatus includes a continuous conveyor mounting arms to carry a random stream of containers along first and second paths of travel; two photoelectric sensors positioned to sense and discriminate among the random stream of containers, and a control mechanism is mounted adjacent to the continuous conveyor to divert selected containers into the first or second path of travel, containers diverted into the second path of travel being urged into oscillating engagement with a vibrating bed for the purpose of settling the contents of the container.
Abstract:
A coverless air conveyor is provided for use with containers of varying heights. The conveyor has a jet board whose jets are substantially vertical with a slight downstream tilt and has sidewalls which form air dams to create a flowing body of air which envelopes and lifts the respective containers and moves them at a very precise speed, the speed being controlled by the small downstream vector of the air along the sidewalls of the containers. In one embodiment the sidewalls are tilted inwardly from bottom to top and air is provided in sufficient volume to vertically stabilize the containers as they move along the conveyor.
Abstract:
Apparatus for picking up and transferring layers of round food articles and the like is disclosed including movable pickup heads mounted on a carriage, each pickup head comprising a vacuum manifold or plenum forming multiple openings on a lower surface and adapted for developing low vacuum, high flow rate conditions variant, a vacuum cup mounted in each of the openings and having a bellows-like construction for permitting expansion and contraction along its axis, a flexible base portion of the vacuum cup forming a seal surface for engagement with one of the round food articles, the vacuum cup also forming a relatively large orifice for permitting relatively unrestricted communication between the vacuum cup and the plenum upon engagement of the vacuum cup with a food article in order to very rapidly produce a vacuum within the cup for causing adherence of the food article. The vacuum cup is also particularly adapted for assuring that the food article is retained upon the vacuum cup until released. A quick connect-disconnect latch assembly is also provided for facilitating replacement of the pickup heads on the carriage. A switching arrangement is also provided which functions automatically upon bottoming out of the pickup heads for initiating or terminating operation of a vacuum source in order to cause the vacuum cups to either engage or release the food articles.
Abstract:
A rotary turntable has an upward step and a peripheral rim divided into pockets by upstanding radial walls. Objects deposited at random near the center of the turntable move by centrifugal force and some gravitional pull toward the step. They are individually separated by vertically reciprocating radial walls and are lifted up to the step and to the rim by lifters vertically reciprocating in time with the radial walls as the turntable revolves. A peripheral wall or band engages the outer ends of the partitions to retain objects in the pockets except for a small part of the periphery through which the pocketed objects are singly discharged.
Abstract:
A refuse handling system including a portable refuse container with a side opening wall. A latching mechanism is provided on the container to lock the wall closed when the container is resting on the ground surface but that is released to unlock and permit the wall to be opened after the container has been lifted from the ground. The latching mechanism is unlocked by a cylinder operator on the fork loader of a refuse vehicle. The unlocking mechanism on the forks is operated as the container is lifted and tipped rearwardly. The refuse will then fall freely from the open container onto a conveyor at the forward end of the refuse vehicle.
Abstract:
A sequential feeder for rapidly feeding fruit to a sequential citrus fruit extractor includes a plurality of chain conveyors, each conveyor being mounted in a vertical plane extending between a lane of a fruit hopper and a lower extractor cup of the extractor. Each chain conveyor includes a plurality of fingers mounted in uniform intervals thereon. A guide plate assembly is provided for each chain for having a contour which causes the chain to move upwardly from the fruit support through a broad curvature adapted to assure that the fingers maintain positive control of the fruit. The guide plate assembly has a sharply curved upper end which causes the fingers of the chain conveyor to pivot rapidly forward after a fruit has been elevated to a height above the associated lower extractor cup such rapid pivoting causes the fruit to be propelled at a high speed into the associated cup. An arched bridge is provided above each conveyor for slidably guiding a fruit as it is elevated from the fruit support to said height above the lower cup and for thereafter guiding the fruit as it is propelled toward the lower cup.
Abstract:
A machine for feeding individual flexible trays from an inclined nested stack to a conveyor or other appropriate surface below the stack. Vacuum heads are mounted to arms that pivot about a horizontal axis spaced from an upper transverse edge of an inclined hopper holding the nested stack. The lower end of the inclined hopper is open for engagement by vacuum heads at the ends of the pivoted arms. The vacuum heads are pivoted by the arms to engage successive trays adjacent a lower transverse edge of the hopper. The arms are then pivoted back with the vacuum heads adhered to a tray, stripping the tray from the stack and pivoting it to a substantially horizontal position where it is released to fall to a surface below. A guide may be employed to direct movement of the tray downwardly.
Abstract:
A vibration or shaking feeder combined with a drum which is rotated at high speed is disclosed. The vibration feeder includes a container having a helical ledge around the inner wall of the container for making articles in the container travel to rise up the helical ledge by vibratory motion of the container. The articles advanced up to the uppermost ledge are transferred to the outer drum rotated at high speed and fed to a next stage for further processing.
Abstract:
A method and apparatus for storing and displaying articles as fruit and the like utilizes a display package that includes a diaphragm member for holding the contents of the package and a pneumatic expander that moves the contents contained in the diaphragm member and the diaphragm member itself toward the top of the display package as the contents are removed or to the bottom of the package as contents are added.
Abstract:
Apparatus for conveying elongated work pieces, such as cucumbers and the like, from a charging station to a transfer zone, and then transferring the pieces into containers such as cans or jars which are arranged in line below the transfer station. The conveyor comprises a plurality of transversely arranged scrapers which slide along the top surface of a horizontal conveyor table from the charging station to the transfer zone. The scrapers are preferably triangular in cross section, with bases flat on the table top and apices at the top. The open space between scrapers is slightly greater than the width of the work pieces, and the height of the scrapers is substantially equal to or less than the height of the work pieces. In the transfer zone, the conveyor table has an opening extending diagonally across the full width of the conveyor and the work pieces drop through this opening onto an inclined slide, which guides the work pieces into the containers.
