    Abstract: A pallet transport device having a securing element positioned between two longitudinal rails in projections of a non-driven pallet transport device. A shaped body is seated on an axle. When docking with a driven pallet transport device, each projection is pushed into a docking receptacle so that a lower, shaped activation surface contacts and pushes the shaped body into a specified position. The shaped body thus pivots about an axis and the pallet can be displaced as desired. When the pallet transport device is undocked, the shaped body pivots upwards and the securing surface locks the pallet in a locking direction. Thus, the pallet transport device can be locked or unlocked without external help and has a high degree of operational dependability.

  • Patent number: 4533055
    Abstract: A rack for supporting drilling tubulars such as drill pipe, collars and the like includes a base and a rail. The rail is coupled to the base by means of two columns, each of which is provided with threads such that the tilt angle of the rail with respect to the base can be adjusted to provide gravity feeding of drilling tubulars to either end of the rail. The rail is provided with two pivotably connected stop plates which move in opposition. The stop plates are controlled by means of an air cylinder to allow only one drilling tubular at a time from those stored on the rack to roll off the end of the rail. Furthermore, both stop plates can be retracted below the level of the rail so as not to interfere with the movement of tubulars onto the rack. The combination of the tiltable rail and the two stop plates provides a rack which can be used to control movement of drilling tubulars on to and off of the rack with a minimum of manpower requirements.

  • Patent number: 4508204
    Abstract: A chute for gravity feeding a plurality of like electrical components (1) to a pick-up station of a robotic controlled automatic assembly system comprises guide rails (2,3) down which components slide with their pins (13) extending between the rails. The rails are shaped to provide a downwardly inclined straight track (5) leading into a horizontal track (6) comprising the pick-up station from which the components are taken by the robot. The transition from the inclined track (approximately 30 degrees to the horizontal) to the straight track, although smooth, is quite abrupt and ensures that the next component is successfully fed from the inclined to the horizontal section of the chute each time its predecessor is removed from the pick-up station. Since the length of the horizontal track is such that only one component can be accommodated at a time, accurate positioning of the component in the pick-up station for access by the robot is guaranteed.

  • Patent number: 4489824
    Abstract: A continuously movable conveyor supports a plurality of articles for movement along a path leading to and beyond a zone at which selected articles are transferred from and returned to the conveyor. At the transfer zone is stop apparatus movable from a position clear of the path of movement of the articles on the conveyor to a position in which it projects into such path of movement so as to engage and stop an oncoming article as the conveyor continues to move. The stop apparatus includes a stop member supported by a parallelogram linkage which is rockable by an extensible and retractable hydraulic ram to effect movements of the stop member into and out of the path of conveyor borne articles. The coupling of the ram to the stop member includes a lost motion connection enabling displacement of the stop member upon engagement of the latter by an article on the conveyor and the ram is yieldably retractable in response to such engagement so as to absorb and cushion the shock of such engagement.

  • Patent number: 4482042
    Abstract: A retarder device for applying gradually increasing braking force to a moving object such as a pallet rolling on a gravitationally actuated conveyor system. The device produces a three-stage application of braking force to the moving object as the object moves along its predetermined path and rolls over a brake wheel that actuates a gear train. The gear train comprises a plurality of intermeshed gears that progressively increases the angular velocity of the rotating gears as the first gear in the train is rotated. A fly wheel carrying at least one pivotally mounted fly weight, and preferably a plurality of weights equally spaced around the wheel, is fixedly secured to the terminal gear of the train. The inertia of the various members of the gear train, the fly wheel, and the fly weights applies the first stage braking force to the moving object.

  • Patent number: 4421226
    Abstract: Rapidly descending articles are decelerated in a segmented walled mechanism which alternately decreases in cross-sectional area to decelerate and restrain an article and subsequently increases in cross-sectional area to permit the article to fall safely to a reception device, such as a conveyor, below. The decrease in cross-sectional area is synchronized with the delivery of the article from an associated fabrication device. The mechanism also includes a synchronously oscillating receiving tube which alternately tracks one moving discharge site on the fabrication device and then returns to engage and track an adjacent discharge site. Orientation of the article is maintained as it passes through the cross-sectional area and onto the conveyor.
