Abstract:
Mechanical belting having transverse rigidity provided by spaced apart transversely extending layers, one of these layers is of compression-resisting material and the other of tension-resisting material, the spaced apart layers giving a beam effect. The layer of tension-resisting material is of troughed shape in a transverse cross section. By this means, the centers of the layers are spaced further apart than their lateral edges, giving an increased resistance to troughing of the belt.
Abstract:
A conveyor for transporting loads between vertically spaced stations. A plurality of shelves are pivotally connected to a pair of chains which are power driven to carry the shelves to the stations. The shelves are tilted at the unloading station for gravity discharge of the load from the front and are tilted in the opposite direction at the loading station to slide the load toward the rear to prevent escape from the front during transport. Guide devices are provided at the tilting axis to prevent deflection of the chain by the tilting forces.
Abstract:
A rigid link for a conveyor chain includes a rigid platform to support a load and means to pivotally connect links to each other to form a chain and for pivotal movement about an axis substantially perpendicular to the plane of the platform. Means is provided to one side of the platform to coact with other like parts of like links when the links are joined together to form a chain to space the platforms of the links apart from each other when the chain is formed into a helix. A conveyor chain capable of formation into a self-supporting helix is provided from a plurality of such links articulated together.
Abstract:
Vertically and/or horizontally traveling conveyor belt and a pocket member for conveying documents, one of said belt and document conveyors having fixed thereto pile fabric and the other complementary hook fabric whereby the conveyor can be releasably secured to and separated from the belt when desired.
Abstract:
A system for inspecting articles on a continuously moving production line and ejecting flawed articles from the production line. One or more inspection stations are located at selected points along the production line to inspect articles passing through the inspection stations for specific types of flaws. Upon the detection of a flawed article, a reject signal is generated and stored in a shift register which transmits the reject signal to a reject mechanism in synchronism with the movement of the flawed container along the production line to cause the reject mechanism to eject the flawed container when the container reaches the reject station. The reject mechanism is so arranged that it is set and reset while out of registry with the production line so that the time required to set and reset the mechanism is independent of line speed. The system is also provided with a control which can set the reject mechanism to eject all containers moving along the line.
Abstract:
A conveyor of like, individual, flat-top articulated links is described wherein the articulating mechanism permits angular movements in a common plane and wherein the individual links are downwardly stepped at a top front surface portion and upwardly stepped at a bottom rear surface portion to provide for nesting interfitting of top and bottom surface portions of successive links permitting fanning out in a common plane without mutual separation while at the same time presenting link supper surface support portions lying in a common plane.
Abstract:
Article handling apparatus including load supporting means in the form of air bearings mounted on decks and actuable to provide a film of air for supporting a load above the surface of the decks. Propulsion means, which may be in the form of conveyor belts, are associated with one or more of the decks and have extended and retracted positions respectively engageable with, and spaced from, a load supported above the surface of the decks on the film of air. The propulsion means may be actuable to an extended position in response to energization of the air bearings so that the path of movement of the load can be determined by energization of a particular group of air bearings, and the direction of movement along the path can then be determined by energization of the propulsion means.
Abstract:
A conveyor capable of bending in vertical and horizontal planes having a central guide and drive chain capable of being driven in two planes and a continuous horizontal carrying surface comprised of multiple load supporting leaves on transverse rods carried by links of the drive chain for relative telescoping motion when the conveyor is bent in horizontal or vertical planes.
Abstract:
A conveyor for moving small ferrous items. An endless flexible belt is supported by one surface of a framework made of a nonmagnetic material. Parallel bars of magnetic material are secured to the framework opposite the belt-supporting surface. Permanent magnets are secured to the bars to provide a continuous magnetic field for attracting the items onto the belt. The belt is provided with parallel strips of high-permeability corresponding to the underlying magnetic bars. The strength of the magnetic flux passing through the items is thus increased.
Abstract:
Method for changing the direction of forward motion of oblong objects and for transferring said objects from a first conveyor on which they are carried in a substantially horizontal first direction in ''''end-to-end'''' relation to a second conveyor which takes said objects ''''side-by-side'''' in a second direction which is also horizontal but substantially at right angles to the first, comprising the step of communicating an upwardly directed impulse to said objects at the end of their travel in the first direction in order that they may be upwardly inclined at a small angle and caused to follow a ballistic trajectory and then to fall back onto the second conveyor under the action of their own weight.
