Provided an automatic feeding device for automotive wheel hub, comprising a separable material rack having material rack units capable of being stacked in turn, a first roller table for conveying the separable material rack containing the wheel hub to a second roller table, and a material rack separating device having a support frame and material rack inserting and taking devices; the second roller table, under which a lifting platform is mounted, is located at a first end of lower part of the material rack inserting and taking device; the material rack inserting and taking device splitting the separable material rack into units, and placing to a third roller table being arranged at a second end of the lower part thereof; a manipulator, for grasping and placing the wheel hub from the material rack unit to a fourth roller table being on a second side thereof.

The present invention relates to automatic and high throughput smart, robotic, autonomous or driver operated, self-propelled field crops harvester (SPFCH) device of row crops, characterized by the need of selecting harvesting ripen crop, during relative long period of time. Harvesting is done by one or more modular robotic harvesting arms hanged on modular booms. When harvesting orchards fruits the SPFCH comprise at least one hybrid robotic arms equipped with a grabbing hand aimed to grab one or more fruit of a an adjacent fruits and also cut its connecting stem, and arm transporting mechanism that gently collects the fruits and transport them to the SPFCH main accumulation area. When harvesting cotton, the SPFCH of the invention may further comprise vacuum sucking hoses and at least one ginning unit that gin the seed-cotton during harvesting and accumulate the seeds in a self-container, and the lint by bales processed, on board by self-press.

A plate advancement mechanism is configured to cooperate with a stack of plates consisting of alternating first and second roofing plates with alternately positioned indexing notches along an indexing edge of the plates. An indexer including at least one indexing tab that projects beneath the indexing edge of the plates reciprocates parallel to the indexing edge of the roofing plates between a first feed position and a second feed position. The indexer first feed position aligns the indexing tab with the indexing notch of the first plates and the indexer second feed position aligns said indexing tab with the indexing notch of the second plates. The indexer first feed position and said second feed position are coordinated with shuttle movement to release the lowermost roofing plate from the stack onto the shuttle by aligning the indexing tab (or tabs) with the indexing notch (or notches) of the lowermost plate.

A pallet lifter for use with a crane enables lifting of materials on a pallet, and then unloading of the materials at one or more locations, such as on a roof of a building. The pallet lifter may include a cage or a retainer frame that contains the material, with a pusher of the lifter used to push out individual portions of the materials. The pusher may unload the material from the top of the pallet of material, such as by sliding it down a ramp. The pusher alternatively may unload the material from the bottom of the stack on the pallet, by pushing it through a slot in the cage. For top-unloading embodiments the pallet lifter may include an assembly for changing the position of the pusher relative to the frame and the pallet, for example moving the pusher downward layer by later as the materials are unloaded.

A device and method for delivering a laboratory sample carrier from a stack of sample carriers includes providing a retaining mechanism that retains the stack of laboratory sample carriers, and an ejector mechanism including a displaceable mechanism comprising a carrier support portion and a carrier transporting portion which are hingeably interconnected. The stack is supported by the carrier transporting portion and the carrier transporting portion is supported by a carrier transporting portion support of the ejector mechanism when the displaceable mechanism is in a first carrier receiving position and configuration. The displaceable mechanism is displaced from the first carrier receiving position and configuration to a second carrier release position and configuration by a further displacement mechanism of the ejector mechanism. This involves moving a lowermost carrier from the bottom of the stack in a carrier accommodating region of the carrier transporting portion as the displaceable mechanism is displaced from the first carrier receiving position and configuration. The displaceable mechanism is displaced such that the carrier transporting portion moves past the carrier transporting portion support and drops so that the displaceable mechanism adopts the second carrier release position and configuration and the carrier in the carrier accommodating region is released. The stack is supported with the carrier support portion when the displaceable mechanism is in the second carrier release position and configuration.

An apparatus includes a pallet dispensing system, including a movable frame being configured to movably hold, at least in part, a pallet stack between a pallet-storage position and a pallet-dispensation position. The movable frame is also configured to hold the pallet stack relative to a pallet transporter in such a way that the pallet transporter is permitted to vertically lift, at least in part, the pallet stack as the movable frame is provided, at least in part, with vertical-lift assistance through stored potential energy.

An autoloading shingle feeder that singulates an associated stack of media into associated individual articles. The autoloading shingle feeder includes a housing including a base, at least one loading belt with a loading surface that defines a horizontally extending loading plane. The autoloading shingle feeder also includes at least one feeding belt that is distinct from the at least one loading belt and includes a feeding surface that defines a feeding plane. The autoloading shingle feeder also includes a carriage assembly that limits vertical movement of the associated individual article when the associated individual article moves from the at least one loading belt to the at least one feeding belt. The carriage assembly includes at least one separator plate including a pressure portion that linearly extends in the loading direction for direct sliding contact with the associated individual article.

For charging a refrigerant-receiving compartment of a cooling container with dry ice, a reservoir vessel has a dispensing opening and a dispensing unit which cooperates therewith and by means of which dry ice blocks stored in stacks in a magazine of the reservoir vessel are ejected one after the other from the reservoir vessel and are respectively inserted into a refrigerant-receiving compartment of a respectively provided cooling container. This makes it possible to provide cooling containers in rapid succession with a precisely metered quantity of dry ice as refrigerant.
