Abstract:
A selective discharge mechanism for gently, yet positively, ejecting fruit or other damageable articles from a conveyor comprised of a spaced pair of thin supporting belts. The discharge mechanism includes a pair of rotary spiders which are positioned closely adjacent to and just inside of the upper runs of the supporting belts with each spider including three relatively flexible and radially extending arms equiangularly spaced 120.degree. apart and projecting from a central hub mounted for controlled rotary movement. A rubber abutment member is provided at the distal end of each of the arms for resilient contact with the undersurface of a fruit on the conveyor. The discharge mechanism is selectively triggered by signals which signify the approach of a fruit, and such signals may cause one of the spiders to be rotated through 120.degree. to permit one of its projecting abutment members to flexibly engage the lower undersurface of the fruit and deflect the fruit laterally from the conveyor in the desired discharge direction.
Abstract:
Food elevating apparatus comprises a hopper for holding articles to be elevated in liquid suspension. An aspiration chamber having an outlet is included, with a lift tube communicating at one end with a hopper and at the other end with the aspiration chamber. A venturi nozzle extends into the aspiration chamber opposite the outlet and adjacent the other end of the tube, and means are included for pumping a fluid through the nozzle whereby the liquid suspended articles are drawn through the tube and out of the chamber.
Abstract:
Method and apparatus for handling and orienting elongated articles (e.g., asparagus) having a center of gravity displaced from the geometric center in a direction away from the lighter and toward the heavier end thereof. Employs the principle of tilting articles about their centers of gravity, together with moving surfaces upon which the articles are supported. The articles are caused to tilt with their heavier ends foremost and drop through one or more gaps formed between moving surfaces. Conveyor means collects the articles and delivers them with the desired lengthwise orientation for further processing. In certain embodiments the conveyor means may collect the articles within a given length range. Also in one embodiment the means provided for receiving oriented articles discharging from the orienting apparatus functions to retain the desired orientation in the discharge zone and to convey the articles away from the discharge zone for further processing. An article feeding device incorporates a V-shaped trough feeding a plurality of V-shaped lanes down an incline for controlled feeding of multiple lanes of the orientor apparatus.
Abstract:
An auger for a conveyor comprising an elongated shaft capable of extending along a curvilinear axis, a flexible, rotatable tube telescoped over the shaft and an elongated helical vane of flexible material extending outwardly from the tube. In a typical embodiment, the auger is used with a housing closed along one side with an upright wall and a wall extending downwardly at an angle into relatively close proximity to the auger. The bottom and the other side of the housing comprise spaced apart, elongated rods which support the assembly and permit gravitation of trash from the conveyor. An elongated, rotatable hose above the auger serves to deflect conveyed items toward the closed side of the conveyor for proper transfer by the auger and a shield maintains the conveyed items in proper location with respect to the auger.
Abstract:
An unstacking machine for trays and the like disposed in elevationally stacked relation providing a frame adapted to receive such a stack of trays including powered tray pick-off means mounted on the frame for reciprocal movement successively to engage the uppermost tray in the stack and to remove it laterally substantially horizontally from the stack and powered stack elevating means on the frame operative upwardly to advance the stack through successive increments of travel to position each succeeding uppermost tray in the path of movement of said pick-off means for removing the trays one at a time from the stack.
Abstract:
This mechanism comprises a shuffle feed mechanism having two sets of longitudinally extending serrated members forming a grid or bed, at least one of the sets of being movable longitudinally with respect to the other so as to progress articles from pocketto-pocket or valley-to-valley along the length of the mechanism by pushing of the articles upwardly along an inclined wall of a V-shaped notch and over the apex so as to slide or roll down into the next notch. The sets of shuffle members are elevated at their discharge ends with the outer shuffle members being at a quarter elevation so as to provide a transverse trough-like configuration to cause single filing of articles progressed therethrough. Also the shuffle feed mechanism includes barrier means extending longitudinally so as to confine the articles to a narrow path along which only a single article can be fed.
Abstract:
A rotatable conveyor wheel adapted for moving articles such as fruit or the like. The conveyor wheel includes a hub rotatable about a fixed axis disposed above a surface along which the articles are to be moved. The outer periphery of the wheel is defined by annular resilient cushions which are yieldably engageable with the articles to move the same along the surface. The annular cushions are mounted on a rim which is connected about the hub by a plurality of resilient spokes. By this arrangement, the rim and cushions may move relative to the fixed axis of rotation to accommodate articles of a variety of sizes or variable volumes of articles.
Abstract:
A filler for bins has a supply conveyor with a stationary initial portion and an end portion movable on said stationary portion to lift and lower in a bin in response to a jack controlled by either of two sensing panels on the margins of a deflector frame, hanging as a pendulum from said conveyor end portion, to lift said end portion when one of said sensing panels is abutted by produce in said bin.
