Abstract:
Apparatus for stacking selected layers of products on a pallet comprises an upstanding frame having two side walls, a back wall forming a close with the side walls, an open entry side and an open uppermost end defined by peripheral frame members. Clamp means circumscribe the uppermost end in unobstructive overhead relation within the close and surrounding frame members to provide an inwardly directed clamping pressure between the side walls and between the back wall and frame members positioned above the entry side. Clamping pressure is generated by inflatable air bags positioned between the peripheral frame members and pressure plates facing inwardly of the close. Layers of products from successive pallet loads are placed by a forklift truck into the apparatus through the open side. A selected layer is raised and supportively clamped. The remaining pallet load is lowered and withdrawn. Successive pallet loads of different products are placed into the apparatus and raised to engage the lowermost surface of the previous clamped layer which is then released. The combined load is raised to the next selected layer and reclamped, the remainder being lowered and withdrawn. Loads extending above the apparatus are confined within a safety cage in a further embodiment which also includes a safety curtain to support the load in the event of clamp means failure. On completion of stacking, clamping pressure is released and the entire load of assorted product layers is lowered and withdrawn.
Abstract:
Fruit or other objects placed on the conveyor and spun by the conveyor are properly oriented on the conveyor by the method and apparatus of the invention by ejecting one or more adjacent touching objects or ejecting objects which form stacked triplets. An optical sensor determines wherein there is or is not a gap between objects and relates that gap detection to the position of the objects on the conveyor. Detection of a continuous signal through a controller circuit causes a downstream solenoid to be energized according to predetermined timing. The solenoid in turn, when energized, rotates a finger which is coupled to, carried with the conveyor system and situated underneath the pocket between adjacent spools. The finger rotates upwardly and ejects the objects sitting in the pocket, thereby removing the misplaced or touching objects on the conveyor belt.
Abstract:
An apparatus for unloading fish from a hold of a boat adjacent an unloading site has a carriage movable horizontally at the site along the boat, an articulated arm, and an endless conveyor extending along the arm. This arm has a rigid inner section having an inner end pivoted about a horizontal inner axis on the carriage and an outer end, a pivot defining an outer horizontal axis at the inner-section outer end, and a rigid outer section having an inner end pivoted on the inner-section outer end at the pivot and an outer end. An inner actuator braced between the carriage and the inner section can pivot the arm on the carriage about the inner axis and an outer actuator braced between the arm sections can pivot the outer section about the outer axis on the inner section. The conveyor extends along the arm from the inner-section inner end to the outer-section outer end and has a carry stretch on one side of the sections and a return stretch on an opposite side of the sections. A multiplicity of holders spaced along the conveyor each include a pair of separate laterally spaced buckets defining a central gap. Support wheels on the arm engage the belt in the gap between the buckets.
Abstract:
Merchandising apparatus and method wherein there is provided an upstanding hollow structure which is multi-sided and has grid walls defining a series of compartments. The structure has vertical columns surrounding it and guiding robot carriages carrying robots which can reach into the compartments, withdraw articles and place them onto a descent conveyor. The descent conveyor lowers the articles onto a transfer conveyor which transfers them to a packing station. The requirements of a customer are determined at an order station by examination of a visual display unit. The order station can be operated from within a vehicle and the customer need not leave his vehicle until the order has been packed at the packing station. Loading of the compartments of the structure is effected from a storage basement by an elevator moving through a floor opening and upwardly within the hollow structure.
Abstract:
A bucket elevator system capable of being driven bi-directionally. The system having a plurality of pivoted buckets supported between two endless chains. Each bucket having a primary guide boss with an upper surface and a guide surface thereon. Guides arranged to contact the upper surface of the primary guide boll to restrain the pivotal movement of the buckets.

Abstract:
The conveyor system is made of a plurality of spools connected by chains at each end of the spool. The space between an adjacent pair of spools defines a pocket. An ejector is carried by the chain within each pocket to eject fruit from the pocket. The ejectors are selectively activated by solenoids lying underneath the chain and mounted on a conveyor channel across which the chain and spools are pulled. An over-the-end detector detects whether fruit passes over the end of the detector and has not been otherwise ejected from the conveyor system. Depending upon the periodicity and the timing in which fruit passes over the end of the conveyor, it can be determined whether one or more ejectors are damaged, or whether ejectors or solenoids are inoperable, and in each case which one.
Abstract:
A conveyor roller assembly comprises a roller supported at opposite ends on first and second opposing end supports with first and second axle members. Each of the axle members comprises a stub axle having one end securely fixed to a mounting flange. Each mounting flange is attached to a respective one of the end supports with the stub axles protruding into an adjacent end of the roller for supporting the roller between the end supports. A bearing member is inserted in each end of the roller for engaging the axle members. Preferably, the mounting flange comprises a molded plastic element having a generally flat, elongated configuration with a pair of spaced apertures for passing of mounting screws therethrough.
Abstract:
A device for placing elongated objects transversely onto a conveyor is disclosed. A preferred device is adapted for moving ears of corn. The preferred device includes a vibratory trough feeder which arranges and moves the ears substantially end to end and into a plurality of lanes, a plurality of drop gates for dropping a group of ears onto a receiving conveyor below, an eccentric conveyor for moving the ears from the lanes into the drop gates, a mechanism for actuating the drop gates, and a receiving conveyor capable of traveling in a direction substantially perpendicular to the lanes, and located beneath the drop gates.
Abstract:
An apparatus for aligning and uniformly orienting fish includes a shuffle feed device for aligning and discharging fish in a single line and a conveyor having a longitudinal upper run positioned for receiving and conveying aligned and discharged fish in a single line, in which fish are orientated in the longitudinal plane of the conveyor. A sensor including an upper photocell and a lower photocell is positioned at a downstream end of the conveyor such that, in operation, the sensor distinguishes between head-end-first and tail-end-first orientations of fish passing the sensor based upon the sequence of activation of the photocells. Fish passing the sensor are uniformly oriented in the same orientation by control of the sensor.
