With a conveyor, in particular a positioning conveyor, having a driven chain system, higher transporting speeds, together with longer service life and less noise nuisance, are made possible by supporting the chain system on an endless runway.
A trolley for use on a conveyor track having two channel section portions arranged with their mouths facing towards one another has two pairs of load bearing wheels mounted on respective ones of a pair of carriers. The carriers are received in respective slots formed in a body of the trolley, these slots having open mouths which face along the track so that the carriers can be withdrawn from the body while the load bearing wheels remain in engagement with the track. The carriers, with the load b...
A conveyor adapted to accumulate articles includes a number of supporting rollers arranged in two rows longitudinally thereof, a drive chain interposed between the two rows of supporting rollers, pushers tiltably mounted each at the approximate midportion of its length on the drive chain at specified spacing and each having an upper projection projecting upward from the chain to engage the article and a lower projection carrying a roller and projecting downward from the chain, and levers tiltabl...
A conveyor comprises a plurality of interconnected cradles and a rotatable member mounted in each cradle. The rotatable members extend above the respective cradle for rolling contact with an object placed on the conveyor to allow the objects to move relative to the conveyor.
A conveyor having a frame, a piston and cylinder unit operable by means of pressure fluid and secured in the frame, a spring assembly for actuation of the piston, a holder mounted on the frame and reciprocable by means of the piston and cylinder unit and carrying a conveyor path for receiving articles. The piston and cylinder unit has inlet and outlet valves and throttle means at the outlet of the outlet valve. A control rod connected to the piston of the piston and cylinder unit is adapted to a...
A conveyor assembly comprising a plurality of generally crescent-shaped, adjacently oriented conveyor pallets presenting a flat article supporting surface and adapted to follow both linear and nonlinear paths of travel which may either be horizontal or inclined upwardly or downwardly; the conveyor pallets being movable longitudinally along the aforesaid paths in response to actuation of one or more friction drive assemblies disposed below the pallets and adapted to operate independently of one a...
Disclosed herein is a conveyor structure having three pans which are in side-by-side relationship and each of which is movable fore and aft independent of the others. Rotating cam means are provided for moving each pan aft, letting each pan move forward, and stopping such forward movement relatively suddenly. By continued repeating of the rotation of the cam means, particles which fall on the pans are fed forwardly thereof, and onto a lateral pan which moves in a manner similar to the movement o...
A conveyor having a plurality of rolls between sections of the conveyor which sections are arranged so that the conveyor will support a load applied in first direction but may be rolled up into a roll for easy transport by a force applied in a direction opposite to said first direction.
A chain driven conveyor apparatus. A drive end and a tail end, sprocket wheels at the drive end and wheels at the tail end having peripheries of greater width than the chains and of uniform circumferential and transverse continuity over which the chains travel. A plurality of flights pivotally connected at each end to a chain, and means at the tail end of the conveyor limiting transverse movement of each flight as it reverses its direction of travel at the tail end of the conveyor.
