A corner unit for a feed conveying system includes a housing and a wheel. The housing defines a cavity and a track. The track is configured to receive a material conveying string. The wheel is disposed at least partially within the cavity of the housing and is configured to rotate within the cavity. The housing includes a plurality of ridges protruding into the cavity. The wheel includes a central hub, an outer rim, and one or more spokes extending from a first end coupled to the central hub to a second end coupled to the outer rim. At least one of the one or more spokes is swept such that, when the wheel is rotated in a first direction, the second end trails the first end such that rotation of the wheel in the first direction sweeps material that enters the cavity from the cavity and into the track.

An extended life conveyor chain in which a wheeled chain member (e.g. a chain link or chain supporting trolley) includes a projecting detent which engages a detent receiver on a load bearing wheel inner member locking the inner member against rotation with respect to the link. A rotating outer wheel rotates around the inner member. This relieves torsional pressure on a swaged connection between the inner non-rotating wheel portion and a fixed axle on the link and prevents resulting wear.

The invention relates to a transport conveyor curve including a multitude of parallel curved tracks, wherein the separate parallel tracks are driven by a conical drive, wherein the contact angle of each of the individual tracks with the conical drive is substantially equal in comparison to the contact angle of the other individual tracks.

This disclosure presents a product display and merchandising device, system and method that may include multiple such product displays and merchandising devices, and a method for dispensing products to customers using such product display and merchandising device. The merchandising system may efficiently utilize storage space and provide an aesthetic display by automatically aligning different products to a front display surface. The merchandising system may use multiple holders or clips on a conveyor belt to hang and display products. A customer may pull and remove a front piece of the products. As the customer pulls the front piece of merchandise or product, the action moves the conveyor belt and brings a next piece of products forward, to the position that the front piece of the product previously occupied. As such, the merchandising system may enable customers to freely remove products and maintain a tidy and neat display of the products.

A conveyor chain having links joined by link pin biased into any of multiple operating positions with its positioning head blocked against rotation by engagement with a detent on a positioning link. The pin can be lifted so that its head is above the level of the detent, rotated to a new operating position, and allowed to be biased back into its position with the head again blocked against rotation by the detent, whereby the wear surface of the pin can be changed to accommodate for chain wear occurring when a link rotates relative to the link pin.

A chain for a vacuum conveyor, includes a plurality of links each having a flat front surface for placing a conveyance object and a back surface facing to a suction portion. A plurality of adsorption holes each having a large opening area on the front surface and a small opening area on the back surface is formed in the link.
