FIELD OF THE INVENTION
The present invention relates to textile ring spinning machine. More
particularly. the present invention relates to spindle arrangement for textile
Ring spinning machines.
BACKGROUND OF THE INVENTION
In textile spinning mills, the cotton is converted into yarn through a series of
machines. Ring spinning machines are the resultant yarn producing and
crucial machines in textile spinning mills. Textile roving materials produced
from roving frame machines are usually fed into the ring spinning machines.
The said ring spinning machines deliver the final stage of cotton in spinning
line, so called yarn. The fed roving materials are drafted by means of a
drafting arrangement. Further the drafted fiber is spun into yarn by means of
ring and traveler arrangement. The spun yarn is further wound on a cop,
which is placed on a spindle. The ring spinning machine is usually divided
along the length by a plurality of sections in two rows throughout the machine
frame of about 75 meters long. The spinning frame usually consists of up to
1824 spindles totally 'on two rows (i.e.. 912 spindles on each row). The center
to center pitch distance / gauge length between two adjacent Spindles is 70 mm or more, in the existing ring spinning machines.
In the existing ring spinning machine, the increased space between adjacent
spindles calls for the increased raw material consumption for the associated
components of ring spinning machine while manufacturing, resulting in
increased cost. The existing ring spinning machine also occupies higher
footprint in textile mills after installation, also resulting ih higher capital cost
and recurring cost. Due to modern requirement in the Textile spinning
industries, there is a need of optimizing the production of textile Ring spinning
machine within the existing space. There is need of development of new
spindle arrangement which is optimized to increase the production of the Ring
spinning machine with the existing layout.
There exists a need to overcome the above-mentioned disadvantages. to
which the present invention provides an improved solution. The present
invention provides a solution by reducing the spindle gauge within the
available area in existing spinning mills.
OBJECTS OF THE INVENTION
The main object of the present invention is to provide a spindle arrangement
which reduces the footprint of the existing ring spinning machines.
_ Another objective of the present invention is to provide a spindle arrangement
which reduces the working length of the ring spinning machines when
compared to the existing arrangement.
Yet another objective of the present invention is to provide a spindle
arrangement for the ring spinning machine which increases production.
SUMMARY OF THE INVENTION
The present invention provides a spindle arrangement for a ring spinning
machine. A roving is fed from the roving bobbin in the creel. The fed roving is passed to a drafting roller by means of condenser. The said roving is further
drafted in the drafting zone, ie, the linear dénsity of the roving is reduced. The
drafted fibres are futther imparted with twist by means of ring and traveler.
The twisted fibre strand known as yarn is further wound on cop placed on a
spindle. The plurality of spindles is arranged on the spindle rail‘ The axial
distance between two adjacent spindles is called spindle gauge. The spinning
machine has multiple sections, each section consisting of a predetermined
number of spindles.
According to the present invention, the textile ring spinning machine
comprising a creel zone, a drafting zone and a spindle zone, wherein the
axial center to center distance between two adjacent spindles is reduced to
64 to 66 mm, and wherein the length of each section is in the range of
1536mm to 1584 mm.
According to an embodiment of the present invention, the total number of
spindles in a ring spinning machine has increased. Each section consists of
24 spindles and a plurality of sections are adjacently arranged along the
length of the spinning machine. The length of each section is in the range of
,1500mm to 1600mm, preferably in the range of 1536mm to 1584mm. most
preferably 1560mm.
According to an embodiment of the present invention, spindle gauge interval
of the spinning module is redefined to 64 to 66 mm, preferably 65 mm, and
thus the section length is redefined to 1560 mm. The spindle gauge reduction
in ring spinning machines is a vital parameter that significantly improves
production efficiency. By reducing the spindle gauge, the number of spindles
per unit length is increased. which leads to increased production efficiency. As there are more spindles in a given length, a higher quantity of yarns can be
simultaneously produced. All the corresponding associated components of
ring spinning machine are aligned to the redefined spindle gauge length
suitably. This leads to a substantial increase in machine productivity.
Moreover, it allows for better utilization of the available space on the ring
spinning m‘achine, optimizing the production capacity of the ring spinning
machine. The total number of spindles in ring spinning machine can be
extended to 2400 or more spindles according to the present invention.
Other aspects and advantages of the invention will become apparent from the
following description, taken in conjunction with the accompanying drawings,
illustrating by way of example the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION
According to one of the preferred embodiment of the invention. a spindle
arrangement of textile ring spinning machine (1) is shown in Figures 1 & 2.
The textile spinning machine (1) according to the present invention is not only
limited to ring frame but also can be a compact yarn ring spinning machine
and the like wherever the yarn spinning takes place.A roving is fed from the roving bobbin (3)
in the creel (2). The fed roving is
passed to a drafting assembly (4) by means of a condenser. The drafting
assembly (4) consists of rubber cot rollers arranged over fluted bottom rollers.
The said roving is drafted in the drafting assembly (4). The linear density of
the roving is reduced by varying the speed of the drafting rollers. The drafted
roving is further passed through a yarn guide (6) to a ring and traveler (5). A
twist is introduced to the fiber bundle with the help of the said ring and
traveler (5). The twisted fibre strand known as yarn is further wound on a cop
which is placed on a spindle (7).
The spindles (7) are arranged on the spindle rail (8). The center-to-center
distance between two adjacent spindles, that is spindle gauge (G), is reduced
to 64 to 66mm, preferably 65mm according to the present invention, so that
the number of spindles (7)
in a spinning machine is increased, by way of
addition of sections. The length (L) of each section is in the range of 1500mm
to 1600mm, preferably 1536mm to 1584mm, most preferably 1560mm.
According to the invention, the spinning module gauge (G) interval is
redefined to 65 mm and thus the section length (L) is redefined to 1560 mm.
The spindle gauge (G) reduction in ring spinning machines (1) is a vital
parameter that significantly improves production efficiency. By reducing the
spindle gauge (G), the number of spindles (7) per unit length is increased,
which leads to increased production efficiency. As there are more spindles (7)
in a given length, a higher quantity of yarns can be simultaneously produced.
The spindle gauge (G) is reduced so that the same length of the ring spinning
machine can accommodate more number of spindles (7), which results in
increasing overall production of the ring spinning machine (1). The redefined
spindle gauge (G) interval according to the present invention facilitates space saving of 120mm per section which results in 4.5m footprint savings for
existing 1824 spindle machines. The total number of spindles in ring spinning
machine can be extended to 2400 or more spindles according to the present
invention. Also, the addition of sections as per the above space savings will
enhance 8% productivity with less raw material consumption.
In view of the present disclosure which describes the present invention, all
changes, modifications and variations within the meaning and range of
equivalency are considered within the scope and spirit of the invention. It is to
be understood that the aspects and embodiment of the disclosure described
above may be used in any combination with each other. Several of the
aspects and embodiments may be combined together to form a further
embodiment of the disclosure.
