Abstract:
A conveyor system or plant has linked carriages including at least one driver carriage which has a motor unit for moving the linked carriages along a rail path. The rail path has a pair of side rails on which freely-rotatable wheels of the carriages run and a central rail upon which the motor unit of the drive carriage acts. Power for the motor unit is taken, through sliding contacts, from feed rods along the path.
Abstract:
In a sorting apparatus wherein the items to be sorted are laid on planes consisting of revolving belts that effect the unloading in predetermined points of the path, the motor that controls the rotation of said belts is linked to the same by means of a drive comprising a flywheel and a joint, the latter being controlled in turn by means that may sense the speed of rotation of the belt. The motor is actuated a few seconds before the unloading takes place, so as to store up sufficient energy in the flywheel; in correspondence of the collecting area, the joint is actuated to make the belt rotate and to unload the item.
Abstract:
A conveyor system for sorting items has a conveyor and discharge system consisting of a rotatable belt on a carriage, as well as motor-driven devices at collecting stations to rotate the belt and effect discharge.
Abstract:
A carriage of the tiltable plate kind for a sorting apparatus has a carrying structure having idle wheels for running in a feed direction along rails on one side of the carrying structure and a pair of spaced uprights projecting from the opposite side of the carrying structure. A frame is hingedly linked to the one side of the carrying structure, the frame having pairs of wheels for engaging opposite sides of a fixed rail. A motor drives at least one wheel of the pairs of wheels of the frame for self-driving the carrying structure. A plate is hinged to end portions of the uprights for rotation about an axis substantially parallel to the feed direction of the carrying structure. A rotatable threaded shaft is between the uprights in the feed direction of the carrying structure. A guide is along the carrying structure in the feed direction thereof and a cursor is on the guide and engaging the threaded shaft for movement along the guide in the feed direction of the carrying structure by rotation of the threaded shaft. A pair of cams is on the plate on opposite sides of the threaded shaft transversely of the feed direction for engaging the cursor, the cams having symmetrically equal contours for tilting the plate in either direction upon rotation of the threaded shaft and movement of the cursor.
Abstract:
A carriage for a transport and sorting machine having tracks and a carriage-dragging device therealong has a carriage support. The carriage support is dragged along the tracks by the carriage-dragging device, but a tiltable object-carrying plate on the carriage support is tilted by an electric motor on the carriage support and movable therewith.
Abstract:
A sorting and/or conveying system and relevant working plants wherein there are used a set of carriages preferably automatically tilting, dragged along a pre-determined path, there being provided a preferably tubular guide with a longitudinal opening, on the inside of which there glide a certain number of spindles or the like, worked, through proper openings made along the guide, by one or more driving wheels linked to the power plant, to some of these spindles there being fastened the supports of the carriages.
Abstract:
A loading/unloading belt movement monitoring device includes magnets integral with the transportation carriage for providing a magnetic field which changes in time as a function of the speed of the loading/unloading belt and sensors on the machine frame for generating a signal indicative of the changing magnetic field, and used to monitor the movement of the loading/unloading belt.
Abstract:
The unit includes an overhead line along which a large number of trollies or sorting containers move. Each is provided with a moving base like a small rotating mat enabling collection and depositing of packages to be sorted along the line. Each of these bases is mounted onto its respective trolley by way of a telescopic structure and along the line there are mechanisms to position each cell at a height corresponding to that of the collection devices where the packages are to be unloaded.
Abstract:
A method for controlling the exact positioning of the items to be sorted in an automatic sorting plant, comprises a plurality of carriages or units, each provided with a revolving belt which moves in a direction orthogonal to the direction of feed of the unit in order to unload the carried item. The method uses a loading mechanism which comprises a plurality of revolving loading belts, arranged head to head and angled at 45.degree. with respect to the direction of feed of the units. The method according to the invention provides that, at the moment of loading, the unit belt is set in rotation and its speed is adjusted as a function of the speed of the item to be sorted, so that the loading takes place at a null relative total velocity.
Abstract:
An apparatus for feeding, selecting and sorting has a coding and feeding unit, a sorting machine and a synchronizing unit. The coding and feeding unit has a keyboard for keying in codes of respective unloading-station destinations of respective items thereat and conveys the items from the keyboard. The sorting machine has a monorail of T-shaped cross section, a plurality of conveying devices for conveying respective items in one direction along the monorail, a chain for moving the conveying devices along the monorail in the one direction one after the other, and pairs of feed rods spacedly parallel to each other, the pairs of feed rods being spaced along the monorail for defining an unloading station at each pair of the feed rods therealong and spaced from the monorail for sliding contact with slidable contacts of each conveying device as it moves therepast along the monorail in the one direction. Each conveying device has at least two pairs of idle wheels with substantially horizontal axes supporting the conveying device on the monorail for movement in the one direction therealong, at least one pair of idle wheels with substantially vertical axes for guiding the conveying device along the monorail in the one direction, a pair of rollers and a rotary belt thereabout for receiving the respective item of the conveying device and unloading the item by rotary movement of the belt transverse to the one direction, a permanent magnet D.C. electric motor for rotating the rotary belt, and the pair of slidable contacts connected to the motor. The synchronizing unit successively receives the items from the coding and feeding unit and feeds them respectively to the conveying devices. For this, the synchronizing unit has three rotating belts positioned one after the other, the speed of the rotation of the three rotating belts being controllable independently of one another.
