Definitions

  • This invention relates to a universal for use in a universal roller conveyor.
  • Universal roller conveyors are utilized so that items of piece goods which are being transferred therealong can be deflected from their original direction of travel and can be moved in a new direction of travel. Such conveyors thus provide for universal movement in the sense that the conveyed item or items can move translationally of the upper conveyor surface in any direction.
  • roller conveyors Two general types of assemblies are utilized in such universal roller conveyors.
  • One type uses coaxial pairs of roller bodies rotatable perpendicularly to the original direction of advance of piece goods along the conveyor.
  • the roller bodies carry along their peripheries, small rotatable rollers which are staggered in position and which are rotatable in the original direction of advance.
  • This type of arrangement is not entirely satisfactory since it consists of so many individual parts that the cost of the conveyor becomes quite expensive.
  • the other known type of prior art arrangement uses a disk-type middle rib and side ribs along opposite surfaces thereof, the side ribs supporting individual small rollers.
  • Another object of the present invention is to provide a universal roller assembly for use in a universal roller conveyor, such assembly having the airgaps and spaces reduced to a minimum so that items being transferred along the conveyor will not become caught in the gaps.
  • Another object of the present invention is to provide a universal roller assembly which is compact in configuration and which is capable of extended periods of maintenance-free operation in a conveyor system.
  • FIG. 1 is a side elevational view of a universal roller assembly in accordance with the principles of the present invention
  • FIG. 2 is a plan view ofthe assembly of FIG. 1;
  • FIG. 3 is a sectional view taken along the line 33 of FIG. 1.
  • FIG. I a universal roller assembly generally designated 10, which, as shown in FIG. I is of a circular cross-sectional configuration.
  • the assembly includes an axially elongated central tubular sheath 12 through which a shaft on a fixed pin can extend.
  • the sheath 12 thus provides a bearing mount which enables the assembly to be mounted in a manner which enables it to rotate about the axis extending through the sheath, and when the assembly rotates in this manner, it acts as a conventional cylindrical roller.
  • a circular center disk 14 is attached to the sheath l2 intermediate its ends.
  • the disk 14 is of a corrugated configuration in that it is provided with an alternating series of peaks and valleys.
  • the peaks on the upper surface of the disk 14 form the valleys on the lower surface thereof, and vice versa.
  • the number of valleys along each surface of the disk 14 corresponds to the number of rollers to be carried since each valley or depression 16 serves as a pocket within which a roller roller assembly adapted can be rotatably mounted.
  • Such means includes a generally Y-shaped rib generally designated 18 which is formed of a center leg 20 extending radially outwardly from the sheath 12 and a pair of spread legs 22, 22, each of which is provided with a central bore or aperture 24.
  • the angle at which the legs 22, 22 are spread apart corresponds to the angle at which the adjacent ribs 18 are themselves spread apart.
  • one leg 22 from one rib means 18 is parallel to one leg 22 from the next adjacent rib means 18, and a linear shaft or pivot pin 26 can extend perpendicularly between these adjacent parallel legs 22, with the ends of the pivot pin 26 being mounted in the apertures 24.
  • Each pivot pin 26 thus spans across a valley or pocket I6, and all pivot pins on the same side of the middle disk 14 are in a common plane, which plane extends perpendicularly to the central axis of the assembly 10, which is the axis running centrally through the sheath 12.
  • the disk 14 is considered as having an upper surface and a lower surface, all pivot pins 26 above the upper surface are in a common plane, all pivot pins 26 beneath the lower surface are in a common plane, and the two planes are parallel to each other and perpendicular to the cen tral axis of the assembly.
  • a roller 28 is mounted on each pivot pin 26, such roller being generally barrel-shaped in configuration.
  • the roller 28 has a body formed as a prolate spheroid, with the ends thereof being truncated to provide parallel flat surfaces.
  • the roller 28 has a central bore extending therethrough for receiving a pivot pin 26 which mounts the roller in a pocket 16.
  • the degree of curvature of the roller body is such as to correspond with an arc of the middle disk 14 so that when a roller is properly mounted upon its pivot pin 26, the outer surface of such roller coincides with a portion of the outer surface of the disk 14, thereby providing the cylindrical configuration to the assembly 10.
  • each roller 28, its pivot pin 26 and the two mounting legs 22 for the pivot pin is such as to enable the roller to rotate, with such rotation being directional axially of the central axis of the assembly 10. That is, the pivot pin 26 can be fixed in position and the roller 28 can rotate thereon, or the pivot pin 26 can rotate and the roller 28 can be fixed thereon, or both the pivot pin 26 and the roller 28 can rotate.
  • each pocket 16 has an arcuate configuration which corresponds as closely as possible to the exterior configuration of the roller 28 to be accommodated therein, so that the roller can nest closely to the disk 14 thereby leaving minimal airgaps or spaces in the assembly.
  • Three of the pockets 16 are provided on one side of the disk 14 an the other three pockets 16 are provided on the other side thereof, in offset relationship. The peaks between the adjacent valleys are equally spaced circumferentially of the disk, since, as aforesaid, the underside of each peak forms a valley.
  • the three rib means 18, which are mounted on the peaks, are spaced apart and the legs 22, 22 at the end of each center leg 20 are likewise spaced 120 apart.
  • the rib means 18 and the legs 22, 22 are likewise spaced 120 apart, but the lower set of ribs 18 are offset 60 from the upper set of ribs.
  • a rib means 18 is provided centrally beneath each upper pocket 16 and above each lower pocket 16. The length of each roller is such that the ends thereof fit closely adjacent the legs 22 into which its supporting pivot pin is mounted, thereby further reducing any airgaps or spaces.
  • the universal roller assembly 10 of the present invention can be mounted individually on a shaft which extends through the sheath 12, or it can be utilized in conjunction with a number of other similar assemblies 10.
  • the shaft on which the assembly is mounted extends axially of the central axis of the assembly so the entire assembly is rotatable as a cylindrical roller, about such central axis.
  • the individual rollers 28 are rotatable in a direction axial of the central axis. Therefore, when an item of piece goods is fed along the conveyor in which the assembly is mounted, the item is movable both axially of the central axis and transversely of such central axis, which means that the item can be universally moved, in a translational manner, along the conveyor.
  • corrugated center disk member having opposed first and second surfaces and having an alternating series of pockets formed along each such surface, with the pockets along the first surface being offset from the pockets along the second surface;
  • rib means upstanding from each surface ofthe disk between each adjacent pair of pockets;
  • rollers and said disk member being configured to provide said assembly with a substantially cylindrical configuration
  • said pockets having an arcuate configuration corresponding substantially to the arcuate curvature of said rollers.
  • An assembly as defined in claim 1 further including a tubular sheath extending centrally through said center disk member to provide a means for mounting said assembly in said conveyor.
  • each rib means includes a center leg extending radially outwardly from said sheath and terminating in a pair of spread end legs, said center leg and said spread end legs being of a generally Y- shaped configuration, with an end leg from one rib means and an adjacent end leg from an adjacent rib means being parallel and defining at least a portion of said means for a roller which fits therebetween.
  • said mounting means further includes a pin extending between said adjacent parallel legs, with a roller mounted upon said pin.
  • rollers have a prolate spheroid configuration with the ends thereof being truncated to form flat parallel end surfaces.
