Abstract:
A link to be assembled to other similar links to form a chain, such as is used with conveyors, capable of movement in three mutually perpendicular directions comprises a one-piece plastic member of generally U-shaped configuration including a cross piece and two opposed arms. Apertured hubs are formed unitary with the ends of each arm, as well as at the cross piece. A first swivel axle interconnects the cross piece portion of the link to the free arms of the adjacent link, while a second swivel axle interconnects the hubs disposed at the free ends of the link to the cross piece of a third link. The first and second pivot axles are disposed orthagonal to one another thereby providing optimal three dimensional mobility to the chain. Supplemental parts such as lattice plates, solid plates, etc., are secured to the link at the hubs unitary with the arms of the link.
Abstract:
A magnetic conveyor is provided including a plurality of holding fixtures for articles of magnetic material. The fixtures are adapted to be mounted on a power driven endless belt in relatively close proximity. Each holding fixture utilizes a permanent magnet plate disposed between flat magnetic pole pieces, all of which are adapted to be sandwiched between a pair of non-magnetic members. The permanent magnet plate retains a cylindrically shaped article of magnetic material in position within opposed and aligned notches, which latter are provided in the non-magnetic member and extend below the top face of the pole pieces.
Abstract:
The manipulator includes a stationary tipping trough including a pair of longitudinally spaced substantially angular supporting surfaces each having a downwardly and inwardly sloping inlet side and an upwardly and outwardly sloping steeper outlet side. A apir of tipping levers are oscillatable by an associated fluid pressure actuator to engage a longitudinal corner edge of a billet in the tipping trough to tilt the billet so that it rests on a different side. A pair of lifters, having projecting fingers, are oscillatable about the same axis as the tilting levers by a different fluid pressure actuator so that the fingers engage the then lower side of a billet in the tipping trough and move the billet over the outlet sides of the supporting surfaces. The tipping trough preferably is arranged between a billet feeding roller conveyor and a billet discharge roller conveyor, and switch means are provided for engagement with a billet moving along the feeding conveyor. The billets have sloping ends providing respective projecting noses and the switch means are so arranged that, depending upon which switch is engaged by a sloping nose, an appropriate billet tipping operation is initiated. Alternatively, the switch means may be arranged beneath a billet support surface, again for corporation with the nose of a billet, or may be arranged to project into the tilting trough for engagement by the nose of a billet.
Abstract:
The invention is concerned with a method of forming corrugations in one limb of an L-shaped strip of uncured rubber to form an edge for an endless conveyor. The strip is wound around a shaper device so that the strip takes up a curved shape with the outer edge of said one limb placed under tension, and then the shaper device is operated to perform portions of said one limb into corrugations. The portions are held in the deformed positions while the strip is cured.
Abstract:
A fruit feed system comprising a bulk supply conveyor for rollable fruit articles from which fruit is fed through a side discharge opening past a bridge preventing means to guard against fruit bridging across and blocking the opening. Anti-bridging rolls are provided at either side of the opening for projecting article feeding elements to active position anytime bridging begins.
Abstract:
The invention relates to guides for maintaining conveyor belts in the desired path when travelling through a bend, for example at the bottom, or top, of an inclined conveyor. The guides act on the load carrying surface of the conveyor for concave bends and on the lower surface of the belt for converse bends. The guides can comprise various forms of static members, auxiliary belts or endless chains.
Abstract:
A conveyor belt consisting of a core body and rubber covers interposing said core, the core body being formed of a nonwoven sheet of staple fiber webs, the fibers constituting the nonwoven sheet being mutually entangled by needling and at least approximately 80 percent thereof being oriented in longitudinal direction of the belt by drawing of the nonwoven sheet in longitudinal direction, and the nonwoven sheet being sufficiently impregnated with an adhesive. Such conveyor belt is prepared by a process which comprises needling a web of 200-1,000 g./m.2 formed of crimped and 40-120 mm. long staple fibers at a needling density of 50-250 times/cm.2; drawing the needled web in its longitudinal direction by at least 50 percent; impregnating the nonwoven sheet with an adhesive to produce a core body; and pressing rubber covers onto the top and bottom surfaces of such core body. The impregnation of the needled web with the adhesive may be conducted prior to drawing.
Abstract:
THIS INVENTION RELATES TO REINFORCED CONVEYOR BELTS HAVING A LONGITUDINAL REINFORCING LAYER AND A NUMBER OF TRANSVERSE REINFORCING LAYERS CONSTITUTED BY PARALLEL ELEMENTS THAT ARE INCLINED WITH RESPECT TO THE MEDIAN PLANE OF THE BELT. THESE TRANSVERSE LAYERS ARE ARRANGED SYMMETRICALLY IN RELATION TO THE MEDIAN PLANE SO THAT THEIR ELE-
MENTS CROSS EACH OTHER FORMING, WITH SAID PLANE, ANGLES OF EQUAL AND OPPOSITE DIRECTION. THE WIDTH OF THE LONGITUDINAL REINFORCING LAYER IS SMALLER THAN THE WIDTH OF ANY ONE OF THE TRANSVERSE REINFORCING LAYERS BEING BETWEEN 1/4 AND 2/3 OF SUCH WIDTH.
Abstract:
A BUCKLE FOR SECURING WEBBING STRAPS IN SYSTEMS SUCH AS ARE USED TO HOLD DOWN CARGO IN COMMON CARRIES. THE BUCKLE COMPRISES A SHALLOW GENERALLY CHANNEL-SHAPED BODY HAVING A PIVOTED CAM AT A CENTRAL PORTION THEREOF, A ROLLER AT ONE END AND A RESTRAINING PIN AT THE OTHER END. A FLAT HANDLE IS PIVOTED COAXIALLY WITH THE CAM AND LIFTS IT WITH A LOST MOTION CONNECTION. THE BUCKLE IS FASTENED TO ONE STRAP AND THE OTHER STRAP IS FED UNDER THE RESTRAINING PIN AND THE LIFTED CAM, AROUND THE ROLLER AND BACK UNDER THE CAM AND RESTRAINING PIN. THE CAM HAS ROWS OF TEETH WITH A SPACING COORDINATED WITH THE PICKS IN THE WEBBING AND IS SPRING-URGED TOWARD THE STRAP, THE HANDLE BEING INDEPENDENTLY SPRING-URGED TO A FLAT POSITION FLUSH WITH THE BODY. THERE IS THEREFORE NO DANGER OF ACCIDENTALLY RELEASING THE BUCKLE BY STRIKING THE HANDLE.
Abstract:
Heat-resistant conveyor belt consisting of an elastomer mixture with steel wire supporting inserts, the elastomer mixture consisting of nitrile rubber and polychloroprene with the nitrile rubber contents exceeding 50 percent; preferably an adhesive soluble in the elastomers is incorporated in the elastomer mixture.
