DESCRIPTION:
BRIEF SUMMARY
FIELD AND BACKGROUND OF INVENTION
This invention relates to an apparatus for handling textile strand material packages and more particularly to an apparatus capable of adapting to and holding a range of sizes and types of such packages.
As will be appreciated by those familiar with the textile arts, it is frequently desired to package strand material such as yarn or thread in wound packages in order to facilitate handling of the material between process steps in the manufacture of textile materials such as fabrics. One example, intended only for illustration of one application for the invention to be described more fully hereinafter, is in the winding of beams for looms, where many (sometimes hundreds or thousands of) packages of textile strand material are mounted in a creel and material is drawn from the packages and wound about a beam which is later mounted in a loom. Other examples will easily come to the mind of skilled persons.
Textile processes have used a wide variety and range of configurations and sizes of packages formed by winding strand material about elongate, hollow cores. Two examples only are the winding of yarn about right circular cylindrical cores into packages known sometimes as "cheeses" for their resemblance to certain types of cheese and the winding of yarn about conical cores. In both instances, the size of a package core and the size of the completed package can vary, with individual producers often choosing package configurations and sizes for reasons known only to themselves.
As will be appreciated by the thoughtful reader, the proliferation of package types and sizes presents problems for the manufacturer who consumes such packaged strands in the further processing of the textile materials, such as a weaving mill. Unless great care is taken in the consistent selection of strand materials and suppliers, strand materials in a number of various package configurations and types will come into a mill for use. As that occurs, some accommodation must be made to the various sizes and types of packages.
Prior to the present invention, such accommodation had only limited success. More particularly, attempts were made to have mounts capable of receiving more than one size and type of package, and some success had been achieved for adapters capable of receiving and handling two or perhaps three such sizes or types. Many such adapters have used fluid pressure actuators to assure that packages received are held in place for use. Others have provided components which must be manually exchanged in order to accommodate varying sizes and types of packages. As will be appreciated, both approaches have difficulties inherent in them of either increased complexity and risk of inoperativeness or increased need for operator attention and impairment of manufacturing efficiency.
BRIEF STATEMENT OF INVENTION
With the foregoing in mind, it is an object of this invention to provide an adapter capable of being easily mounted for use with a variety of textile machines and of receiving a wide range of types and sizes of textile strand material packages. In realizing this object of this invention, the adapter of this invention has an elongate spindle and elements mounted on the spindle for movement relative thereto and for engaging spaced locations longitudinally of and within an elongate core of a textile strand material package. The engaging elements are coupled one to another and to the spindle in such a way as to facilitate receiving and supporting a wide range of types and sizes of packages.
Yet a further object of this invention is to provide a package adapter of the type described which is capable of being easily and quickly reset by an operator to accommodate a different package that the one last previously used. In realizing this object of the present invention, the difficulties encountered heretofore with prior arrangements are reduced or eliminated.
