A singulator for rollable and slidable articles of compact configuration, such as fruit, has a frame supporting a feeding tray to present the articles at a datum region. One or more conveyors on the frame are available at the datum region. Each conveyor extends substantially horizontally from the datum region in a line and has a number of top surface areas spaced apart along the line. A number of eccentrics on a shaft parallel to the line are arranged in a predetermined polar relationship to move the surface areas up and down in timed relationship as the shaft revolves to approximate waves traveling along the line preferably at increased wave length away from the datum point and with a phase difference between two side-by-side conveyors.
Apparatus for transporting articles, the articles being positioned on bar-like members which in turn are caused to bend periodically in a wave pattern. The periodic bending is controlled to produce a driving force on the articles in a predetermined direction.
A conveyor with a carriage activates actuators which encourage the carriage along a path. The position of the carriage is detected and used to activate mechanical stimuli to advance the carriage position. Only the portions of the device which are directly advancing the carriage are consuming energy thereby providing an efficient conveyor. Various geometries are suggested such that the conveyor function is independent of carriage path. Various forms of mechanical actuators can be utilized to achieve the same results. The devices have function independent of any particular actuator.
A device for arranging in order a random supply of articles including a plurality of article orientating members movable relatively to each other. The members are spaced so that the articles, when orientated, can drop between the members. The members may comprise intercalating elongate blades, alternate blades being arranged to move in unison relative to intermediate blades and may be provided for conveying the orientated articles from between the blades to a receiving station.
Embodiments of a vacuum conveyor system are provided herein. In one embodiment, apparatus for conveying a substrate includes a vacuum sleeve and a plurality of rollers disposed within the vacuum sleeve for supporting and transporting the substrate thereupon. The plurality of rollers is adapted to simultaneously support the substrate thereupon at a plurality of elevations. A leading edge of the substrate is supported at an elevation above an adjacent one of the plurality of rollers in the direction of travel.
A sequencing drop chute apparatus receives a batch of electrical components and feeds them one at a time to a single line conveyor. The sequencing drop chute apparatus includes a support frame with an inclined surface attached to the support frame. A plurality of walls extend upward from an upper portion of the inclined surface and divide the upper portion of the inclined surface into a plurality of chutes. There is at least one chute for each electrical component of a batch of electrical components. A camshaft is rotatingly mounted upon the frame and includes a plurality of eccentric cams one of which is operably associated with each of the chutes for periodically blocking and periodically opening each of the chutes. The cams are arranged so that the plurality of chutes are opened one at a time thereby permitting the batch of electrical components to pass one at a time through the drop chute apparatus to the conveyor.
