Abstract
A framework for mounting a wrapping material film roll spindle upon a film wrapping material dispensing assembly of a film wrapping or packaging machine comprises an external framework fixedly mounted upon the film wrapping material dispensing assembly, and an internal framework pivotally mounted interiorly of the external framework. A spindle is mounted upon the internal framework for supporting a roll of film wrapping material. The external framework comprises a rigidified four-sided framework defining an enclosed space within which the internal framework is disposed such that when the film wrapping material is dispensed, vibrations within the assembly are effectively eliminated or substantially reduced.
Claims28
A framework assembly for pivotally mounting a component with respect to a fixed support of a film wrapping apparatus, comprising:
- a substantially non-movable external framework comprising a plurality of structural members which are arranged in a substantially planar perimeter array and which are fixed at predetermined positions with respect to the fixed support of the film wrapping apparatus so as to define a substantially enclosed space within said substantially planar perimeter array;
- a component to be movably mounted between first and second positions with respect to said substantially non-movable, fixed external framework and said substantially enclosed space defined therein;
- an internal framework, comprising a plurality of structural members arranged in a substantially planar array, upon which said component is fixedly mounted;
- and
- means pivotally mounting said internal framework upon two of said structural members of said substantially non-movable, fixed external framework for permitting said internal framework and said component to be pivotally moved between said first and second positions with respect to said substantially non-movable, fixed external framework and said substantially enclosed space such that when said internal framework and said component are disposed at said first position, said substantially planar perimeter array of said internal framework is disposed in a substantially coplanar manner with respect to said substantially planar perimeter array of said substantially non-movable, fixed external framework, whereas when said internal framework and said component are disposed at said second position, said substantially planar perimeter array of said internal framework, upon which said component is fixedly mounted, is no longer disposed in a substantially coplanar manner with respect to said substantially planar perimeter array of said substantially non-movable, fixed external framework.

A framework assembly for pivotally mounting a roll of film wrapping material upon a dispensing assembly of a film wrapping packaging machine, comprising:
- a film wrapping material dispensing assembly;
- an external framework comprising a plurality of structural members arranged in a perimeter array defining a substantially enclosed space within said perimeter array and fixedly mounted upon said film wrapping material dispensing assembly;
- an internal framework;
- spindle means fixedly mounted upon said internal framework for mounting a roll of film wrapping material thereon;
- and
- means pivotally mounting said internal framework upon two of said structural members of said external framework such that said internal framework and said spindle means are pivotally moved between a first position with respect to said external framework and said substantially enclosed space at which said spindle means is disposed at a first operative position from which film wrapping material can be withdrawn and dispensed from the roll of film wrapping material by said film wrapping material dispensing assembly, and a second position with respect to said external framework and said substantially enclosed space at which said spindle means is disposed at a second operative position where rolls of film wrapping material can be mounted upon and dismounted from said spindle means.

In a film wrapping packaging machine, wherein a framework assembly is provided for pivotally mounting a roll of film wrapping material upon a film dispensing assembly of the film wrapping packaging machine, comprising:
- a fixed framework defining a wrapping station at which articles to be packaged are to be disposed;
- a vertically reciprocable framework movably mounted upon said fixed framework;
- a film wrapping material dispensing assembly movably mounted upon said vertically reciprocable framework;
- an external framework comprising a plurality of structural members arranged in a perimeter array defining a substantially enclosed space within said perimeter array and fixedly mounted upon said film wrapping material dispensing assembly;
- an internal framework;
- spindle means fixedly mounted upon said internal framework for mounting a roll of film wrapping material thereon;
- and
- means pivotally mounting said internal framework upon two of said structural members of said external framework such that said internal framework and said spindle means are pivotally moved between a first position with respect to said external framework and said substantially enclosed space at which said spindle means is disposed at a first operative position from which film wrapping material can be withdrawn and dispensed from the roll of film wrapping material by said film wrapping material dispensing assembly, and a second position with respect to said external framework and said substantially enclosed space at which said spindle means is disposed at a second operative position where rolls of film wrapping material can be mounted upon and dismounted from said spindle means.

A framework assembly for pivotally mounting a component with respect to a fixed support of a film wrapping apparatus, comprising:
- a substantially non-movable four-sided external framework comprising a plurality of structural members which are arranged in a perimeter array and which are fixed at predetermined positions with respect to the fixed support of the film wrapping apparatus so as to define a substantially enclosed space within said perimeter array;
- a component to be movably mounted between first and second positions with respect to said substantially non-movable, fixed four-sided external framework and said substantially enclosed space defined therein;
- a three-sided internal framework comprising a pair of laterally spaced structural side members, and a base member interconnecting lower end portions of said pair of laterally spaced structural side members and upon which said component is fixedly mounted;
- and
- means pivotally mounting said pair of laterally spaced structural side members of said internal framework upon two laterally spaced structural members of said substantially non-movable, fixed four-sided external framework for permitting said internal framework and said component to be pivotally moved between said first and second positions with respect to said substantially non-movable, fixed four-sided external framework and said substantially enclosed space.
