Förderleitung zum Fördern von Gegenständen mit Hilfe von Gas, welches durch eine erste Einblasstelle in die Förderleitung einblasbar ist. Die Erfindung zeichnet sich dadurch aus, daß eine zweite Einblasstelle (28) zum Einblasen von zusätzlichem Gas in die Förderleitung vorgesehen ist.

System for delivering air-filled packing cushions (17) to a point of use in which a continuous string of the cushions (17) is fed into an elongated duct (27) with the string extending longitudinally of the duct (27), and an air flow is established in the duct (27) to convey the string of cushions through the duct (27). In one disclosed embodiment, the air flow is created by a blower (34) mounted externally of the duct (27), with a baffle plate inside the duct (27) directing the air flow in a longitudinal direction. In a self-contained system in which the cushions are made at the point of use, the duct (27) extends vertically, and the cushions (17) are fed directly into the lower end of the duct (27) by a machine which makes them. The string of cushions (17) is discharged from the upper end of the duct (27) into a bin (26) from which they can be withdrawn as needed for use in cartons supported by a stand positioned beneath the bin (26).

An apparatus for manipulating flexible articles comprising an openable dispenser (116) for retaining one article (123) disposed along the dispenser (116) and arranged so that the (116) dispenser continues to support the article (123) when it is opened and in that the apparatus includes movable gripping means (400) arranged to grip the hose (123) at two predetermined positions and thereafter lift the article (123) from the dispenser (116). The gripping means (400) may comprise a pair of spaced-apart grippers (402) or a gripper and suction tube arrangement mounted on a common support (404) and moveable towards and away from the dispenser by a pneumatic or hydraulic piston and cylinder (406) arrangement. A method of manipulating a flexible article is also disclosed.

A pick-up machine for grouping, in an orderly fashion, hosiery items leaving a pneumatic conveyance duct, the device comprising a moving element (2) provided with supporting elements (3) for groups of hosiery items, the supporting elements (3) being spaced from one another on the moving element (2). The device has a device (14) for moving the moving element (2) in order to sequentially position one of the supporting elements (3) below a hosiery item spreading device (5) arranged at the end of a pneumatic conveyance duct for hosiery items so that the supporting elements (3) receive every time a presettable number of hosiery items delivered sequentially by the spreading device (5).

A Feeder for elongate components, in particular components designed with a head, has a feed tube with an inlet orifice which can be connected to a feed line and an orifice in the top region thereof and a gripper with at least two gripping arms (1) which are provided with a front gripping region (2) and a rear pivot axis region (3).

The gripper is arranged in the feed tube which has, in its top region, a lower plane surface and an upper plane surface opposed to it;

The gripping arms (1) each have a guide step (6) which preferably tapers and extends from the pivot axis region to the gripping region (2) on a longitudinal end face (5) turned toward the upper plane surface, the guide step (6) serving to guide the head of an elongate component; and

The gripping arms (1) have, in the gripping region (2), a recess (7) adapted to the external shape of the elongate components to be gripped.

L'invention a trait au conditionnement et à la distribution de petites pièces cylindriques, telles que des rivets.

Le procédé selon l'invention est essentiellement caractérisé en ce qu'on fixe un diamètre de la paroi intérieure du tube (1) contenant une colonne de pièces et muni d'une entrée d'air comprimé, dans un rapport prédéterminé avec le plus grand diamètre ou la tête (3) des pièces cylindriques (2) de manière telle qu'on forme une restriction de débit d'air entre ladite paroi et chaque tête, afin de provoquer une légère différence de pression entre la face amont et la face aval de la tête de chaque pièce, permettant d'engendrer une poussée axiale sur chacune d'entre elles et d'introduire la pièce de la sortie-aval dans l'organe de distribution (12).

Application aux machines à riveter.

Bei einer Anlage zum Transport und zur Behandlung von einander gleichen Körpern, insbesondere Behältnissen, ist einer Verschlußvorrichtung (5) und/oder einem Strahlapparat (9) eine Fangvorrichtung (6, 13) für rücklaufende Körper (1) nachgeschaltet. Hiermit lassen sich Probleme beheben, die andernfalls infolge des Rücklaufs der Körper auftreten.

A tube 10 is held or guided parallel to its length by providing a channel-like structure 38 aligned with the tube and having sides 30, 36 which are spaced apart by a distance less than the diameter of the tube. Circumferentially spaced longitudinal portions of the outer surface of the tube bear respectively on the two sides of the channel. The channel is open to the outer surface of the tube between those longitudinal portions, and the bottom of the channel is spaced from the outer surface of the tube between those longitudinal portions. The tube is held against the channel-like structure by directing a stream of gas (e.g., air) along the channel.

A conveying system for pneumatically conveying fragile, light weight workpieces by timed pulses of compressed air. Each pulse of air is used to propel a workpiece along a path that leads into a downwardly sloping chute and to decelerate the workpiece after travels a selected distance down the chute so that all the initial momentum given the workpiece by the pulse of air is removed such that the workpiece will continue down the chute only under the influence of gravity. By decelerating or retarding the propelled workpiece it is prevented from impacting against queued workpieces, that proceeded it down the chute, with a high velocity that can cause breaking, chipping or jamming of the workpieces.

Um eine bestimmte Raumform aufweisende, mittels einer Transportflüssigkeit geförderte Körper (3) im Durchlaufverfahren einer Druck- und/oder Temperaturbehandlung unterwerfen zu können, wird eine Vorrichtung vorgeschlagen, bei der mittels mindestens einer Wasserstrahlpumpe (11) in einem Rohrleitungssystem eine Strömung erzeugt, in dieser ein Druckaufbau bewirkt und das Rohrleitungssystem gegenüber dem an der die Körper einschleusenden Ansaugleitung (7) herrschenden Atmosphärendruck abgedichtet wird. Hierbei werden die Körper (3) im Bereich der Wasserstrahlpumpen (11) in einer den Strömungsverlauf nicht beeinträchtigenden, Flüssigkeitsdurchlässe aufweisenden Führung (13) geführt und wird die Treibflüssigkeit dem Diffusor (26) einer Wasserstrahlpumpe (11) entnommen und über eine eine Pumpe (16) aufweisende Leitung (TF) der Düse (14) der Wasserstrahlpumpe (11) zugeführt. Zum Aufbau und zur Aufrechterhaltung eines bestimmten Drucks in einem Rohrleitungsabschnitt (48) ist am Ende dieses Abschnitts eine Wasserstrahlpumpe (70) mit entgegengesetzter Strahlrichtung angeordnet.
