Definitions

  • Garbe Attorney-Walter Fred ABSTRACT A package for grinding wheels and method for assembly thereof in the form of an elongated square wheel Supporting container for holding one or more axially aligned grinding wheels of substantially the same diameter therein and having square end covers within opposite ends of the container, and tensioned tied strands of strapping extending across the end covers and axially along the center of each side of the container opposite a line of contact between the inside walls of the container and the wheels.
  • a method of packaging grinding wheels by stacking and centering them upon an end cover. A square container of sufficient length is slipped over the Stack endwise and another end cover is placed over the exposed end of the stack of wheels to fit within the tube. Strapping is then Stretched tightly across the outside of the end covers and along the center of each side of the container to force the wheels together and each side of the container into contact with the periphery of each of the wheels.
  • the applicants invention provides a reduction in labor and materials costs; eliminates the use of sawdust or waste materials; provides multivariable box lengths for enclosing any reasonable number of grinding wheels of approximately the same diameter; eliminates repackaging of already packaged wheels; facilitates easier in-plant packing of grinding wheels and handling and stacking of relatively lighter weight packages for shipment.
  • a plurality of grinding wheels of substantially the same diameter are packaged by stacking them in axial alignment with square end pieces for the container at the ends of the stack and protective deformable separators between them.
  • a length of preformed square container material slightly longer then the axial length or height of the stack is cut from stock that is stored in the form of collapsed flat strips.
  • the preformed collapsed strip is then opened up to form a square elongated container element the sidewalls of which have dimensions slightly longer than the stack of the wheels and when the container is expanded the internal width is slightly larger than the diameter of the wheels so that it may be slipped over the stack.
  • the flat square end covers of substantially the same cross-sectional area as the interior dimension of the elongated container fit within the opposite ends of the container at each end of the stack. Then the stack of wheels and separators, end covers, and the container are tied tightly together with conventional strapping stock. The strapping is extended across the end covers and axially along the middle of each exterior side of the container and is tensioned and fixed to maintain the walls of the container tightly engaged against tangent points on the wheels.
  • FIG. 1 is a perspective view of a grinding wheel package according to the invention
  • FIG. 2 is a perspective view partly broken away showing a flat strip of collapsed but preformed piece of stock from which is cut the container such as is shown in FIG. 1;
  • FIG. 3 is a perspective view showing a table and the components of a package thereon.
  • FIG. 4 is a cross-sectional view through the grinding wheel package.
  • a package which may contain several axially aligned grinding wheels 12 of substantially the same diameter.
  • the grinding wheels 12 may or may not have the conventional relatively thin wheel blotters l4 fixed on opposite sides thereof for mounting the wheels.
  • deformable separators 16 of substantially the same dimensions as the diameter, as the wheels.
  • the separators 16 may be round or square. In some instances the wheel blotters are left off and the wheels may be a type which has a great resistance to breakage and therefore the protective separators 16 may be eliminated if desired.
  • Each end of the stack of wheels is covered with a flat square end cover 20 having sides 20a of a length substantially equal to the wheel diameter which end covers fit within the container 18 and against the wheels.
  • Separators l6 and end covers 20 are made of conventional packaging materials such as, utility board or another pressed fiber product, cardboard, corrugated board, or foam plastic.
  • the square container has an internal crosssectional area at least equal to that of the end covers 20 which covers may be made slightly smaller for ease of inserting them within the container.
  • the four internal or interior sidewall surfaces 18a of the container 18 surround the sides 20a of the end covers and surfaces are in tangential engagement with the peripheries of the wheels 12.
  • the overall length of the stack of wheels and the end covers determines the length axially of the stock and hence the length of the container to be cut from the elongated collapsed flat strip of preformed stock S shown in FIG. 2.
  • the width of the container stock S is selected to match the diameter of the wheels to be enclosed therein and various container sizes are stock piled in the collapsed flat state in a minimum amount of space.
  • the cut length forming container 18 may be constructed of any of the conventional packaging materials such as heavy cardboard, corrugated paper board, plastic and the like.
  • the provision of the completed deformable container stock material in various sizes commensurate with the diameters of the wheels to be packaged forms the essence of this invention.
  • the prefolded shape S that is made up of the four walls of the container 18, joined together prior to the cutting of the container to length to fit the length of the stack of wheels, a convenient number of sizes of stock S can be stored in a minimum of space.
  • the proper size folded stock is selected, i.e., one where the sidewall of the container is approximately the same size as the diameterof the wheels in the stack, and then a proper length of container material is cut from the flattened stock S.
  • the deformed cutoff piece is then opened up and is easily slid longitudinally, or endwise over the stack of wheels to encompass the product to be contained.
  • the strapping or binding 22 may be in the form of a round or flat strand or tape formed of metal, fabric, or fiber reinforced materials which provides the necessary strength and tension to hold the package together. It may be applied, tensioned, and tied by hand but preferably is done with any of the well known commercially available conventional strapping devices on the market suited to apply tension, and fixed the ends of the strap together.
  • the two strands of strapping 22 cross each other at approximately right angles as they extend across the middle of the end covers 20 the strapping 22, extending axially along the middle of each exterior side surface of the container 18 opposite the line of contact or tangency between the periphery of the wheels 12 and the interior side surface 18a of the container 18.
  • the grinding wheels are engaged tightly together and are compressed against the separators disposed therebetween.
  • the middle portions of the end covers 20 and each of the sidewalls of the tube 18 engaged by the strapping 22 are also compressed and forced into engagement with the wheels.
  • a package formed in this manner and properly tied becomes a substantially rigid self supporting block and maintains the wheels in a fixed relation one to another during handling.
  • wheels 12 may be stacked axially directly on a support or table T as shown in FIG. 3.
  • the container 18 may then be slipped endwise over the stack of wheels and separators.
  • an individual wheel, or a stack of wheels may be inserted into an expanded container 18.
  • the end covers 20 can then be inserted into opposite ends of the container 18 after the wheel as the package is being completed by application of straps 22.
  • a grinding wheel package comprising: 7
  • a substantially square container having an axial length slightly greater than the length of said row of wheels, said container having sidewalls each with an exterior and an interior surface which walls encompass and engage the peripheral surface of the grinding wheels along a line of contact substantially along the center line of the interior surface of each of the sidewalls;
  • a grinding wheel package according to claim 1 further comprising: I
