Abstract

In the driving mechanism for driving spindles of a ring spinning frame, wherein spindle alignments of the R side and the L side thereof are divided into a plurality of sub-unit groups of spindles respectively so that a plurality of unit groups of spindles are formed along the lengthwise direction thereof by pairs of sub unit groups of spindles, each pair of sub-unit groups of spindles consist of a sub-unit group of spindles of R side, and a sub-unit group of spindles of L side which faces the sub-unit group of spindles of R side, a plurality of unit driving mechanisms are formed along the lengthwise direction thereof to drive the corresponding one of the above-mentioned plurality of the unit groups of spindles respectively, spindles of each unit driving mechanism are driven by a single spindle tape, and the spindle tape is driven by a driving motor, and such improvement is applied so that the spindle tape is driven by the driving motor by way of at least two driving wheels, and the number of spindles per one driving wheel is less than six.

In a driving mechanism of spindles applied to a ring spinning frame, wherein spindle alignments arranged at right hand and left hand sides of said spinning frame are divided into a plurality of unit groups of spindles, each unit group of spindles being formed by a sub-group of spindles on said right hand side of said spinning frame and said sub-group of spindles of said left hand side facing each other, a plurality of driving mechanisms for driving spindles of said unit group of spindles being provided aligned along a lengthwise direction of said spinning frame, each said unit driving mechanism being provided with an endless tape to drive spindles thereof, said right hand and left hand sides defining an open space therebetween,

wherein the improvement of each side driving mechanism comprises;
a driving motor having a motor shaft,
at least two driving wheels for driving said endless spindle tape,
one of said driving wheels being coaxially mounted on said shaft of said driving motor,
a driving pulley coaxially mounted on each of said driving wheels,
a plurality of tension pulleys for controlling tension of said endless tape,
at least one endless belt extending across said open space and mounted on each of said driving pulleys and drivingly connected to a corresponding one of said driving pulleys disposed at an opposing side of said spinning frame,
said driving wheels and said tension pulleys being alternately disposed at respective positions within said open space and close to a corresponding one of said sub-group of spindles at both sides of said spinning frame in said lengthwise direction such that each of said driving wheels disposed at one said side of said spinning frame faces a corresponding one of said tension pulleys disposed at an opposing side of said spinning frame positioned between an intervening space defined by two spindles, and
the number of said driving wheels is defined by the condition that the number of spindles driven by each of said driving wheels is no more than six in each said sub-group and one said drive wheel having one said pulley disposed thereon at one said side of said spinning frame includes one said endless tape mounted thereon that is in driving communication with a drive wheel and pulley disposed at an opposing side of said spinning frame.
