Abstract: In order to ensure a reliable automated feed of connecting elements to a processing unit, an apparatus, in particular an industrial robot, is provided. The apparatus has a hose pack, in which a feed hose for connecting elements is contained as a supply line. In order to ensure reliable operation and kink protection of the feed hose, the latter is formed from an inner hose which is embedded in a over-molded hose jacket. This measure permits the integration of the feed hose into the hose pack without problems. In addition, the risk of the feed hose kinking is kept small.

Abstract: An automated filling apparatus which propels various deer feed into an elevated deer feeder comprises a cart having a mounted container which is towed by a vehicle to a feeder location. A base of the cart receives an air duct connected to an air blower which supplies an air flow. The apparatus introduces a flow of deer feed into the air flow which is in turn conveyed upwardly into the elevated deer feeder via a second opposing air duct being connected to an elongated flexible hose having an elbow portion at its upper end and retained upon an upper lip of the deer feeder. After activating the blower, a quantity of deer feed is poured into the container and is propelled upward through the tubing and dispensed into the container portion of the deer feeder.
