  • Patent number: 5325954
    Abstract: A strand preorienter is formed by a plurality of spaced parallel preorienter shafts each having a plurality of preorienter discs mounted thereon in axially spaced relationship. The preorienter discs on adjacent shafts overlap and form preorienter partition walls which defined opposite sides of preorienter passages through which the strands fall onto an orienter having orienter passages that align the strands as required. The preorienter passages are significantly wider than the orienter passages and have their outlets positioned immediately above the orienter.

  • Patent number: 5320214
    Abstract: A sealed linear motion apparatus and method are disclosed. The moveable surface of the apparatus is sealed to side members spaced across the moveable surface and adjacent to the opposite sides of the moveable surface. The seal comprises sealing members which make contact with both the side members and the moveable surface. The sealing members are typically made from polyurethane impregnated with polytetrafluorolethylene. In one embodiment, the apparatus is used as a linear position table. A controlled motor precisely positions a plate mounted to the moveable surface. In another embodiment, the apparatus is used as a conveyor in which the moveable surface moves continuously in one direction at a constant rate of speed. Because the apparatus is sealed, it may be used in certain applications such as clean room environments and those requiring wash down of equipment with high pressure, high temperature liquid or environments with abrasive contaminants in the air.

  • Patent number: 5312223
    Abstract: A stacker assembly receives signatures and supports the signatures as an intermediate stack is formed. A jogger assembly engages an intermediate stack supported by the stacker assembly to accurately align edge portions of the signatures. The stacks of signatures are deposited onto a turntable to form a main stack. The turntable rotates the main stack to offset relatively thick folded edge portions of signatures. The stacker assembly includes a plurality of slats which are moved along a first continuous circuitous path by a first drive assembly. The stacker assembly also includes a plurality of slats which are moved along a second continuous circuitous path by a second drive assembly. The drive assemblies move the slats along the continuous circuitous paths with the longitudinal axes of the slats horizontal and parallel. The jogger assembly has jogger plates which extend into central portions of the continuous circuitous paths along which the slats are moved by the drive assemblies.

  • Patent number: 5310307
    Abstract: A device and method are disclosed for moving articles, such as cans, by groups, or tiers, from a pallet to an adjoining surface, such as a belt conveyor. A pair of sweep arms of a sweep unit move about a closed loop path to alternately engage the trailing portion of groups of articles when at a pallet sweep area to urge each group from the pallet. A pivotable retainer arm of a retainer unit, mounted on a reciprocating carriage moved by a driver following a closed loop path, engages the leading portion of the group of articles to be then moved from the pallet and thereafter leads the group from the pallet.

  • Patent number: 5310046
    Abstract: A plastic conveyor belt formed of a large number of plastic belt modules includes outer belt modules having integral sideplates. The sideplates are of heavier material and higher strength, for withstanding stress around the outside of curves and for withstanding edge wear in certain types of conveyor systems. In a preferred embodiment, each sideplate has a depending guide member which may include a hold down tab. In one embodiment, plastic connecting rods which serially connect belt modules are discontinuous in length, made up of several coaxial pieces which are held in place by press fitting at the outer ends. This enables the rod to be of high shear strength in areas of high pulling force, e.g. at the outside of a radius conveyor belt in a curve, but of lower strength extruded construction elsewhere.

  • Patent number: 5307922
    Abstract: A rubber tire individual separation transport apparatus including a rubber tire individual conveyor surface section and a rubber tire sliding surface section separately formed on a slat conveyor surface, with the conveyor having a horizontal charge zone, a sharply inclined individual transport zone, and a horizontal discharge zone. Also included is an upright plate erected for contact with the peripheral surface of a rubber tire at one end of each slat in the individual conveyor surface section. A support plate of such a size as to support only one rubber tire laid flat on said individual conveyor surface is mounted at a larger pitch in the direction of transport than the maximum diameter of the rubber tire being conveyed. A stationary side wall is erected along the side edge of the other end of the slat of the sliding surface section. Cooperative action between the selected tire and the side wall causes frictional force on unwanted tires to cause them to fall back to the supply of tires.

A top plate of each chain link is provided with fingers and recesses disposed between the respective fingers at both a front edge and a rear edge, as viewed in a direction of movement of the conveyor. The fingers are staggered with respect to each other so that the fingers and recesses on adjacent links are adapted to engage with each other. An additional finger is disposed substantially centrally of the chain link in the front edge, as viewed in the direction of movement of the conveyor and the corresponding central recess is provided in the rear edge of an adjacent link. The chain links may be injected moulded plastic links or links blanked from sheet metal.

  • Patent number: 5307918
    Abstract: A power switch assembly is operably connected to the combplate of an escalator for selectively shutting off the escalator in the event of entrapment of some object between the steps and combplate. When an object becomes wedged between the steps and combplate, the latter will be lifted or pushed upwardly away from the steps. The upward movement of the combplate operates a power interruption switch to stop further movement of the steps and handrail. The combplate is supported on the truss by spring assemblies which serve to effectively lower the weight of the combplate so that upward movement of the latter is more readily accomplished. The assembly can be retrofitted onto older existing escalators with heavier combplates than are found in newer equipment.
