Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention relates to an up-and-down swing
mechanism for separated heald frames of a sample fabrics machine,
and more particularly to a mechanism able to automatically control
a portion of heald frames of a sample fabrics machine, and suspend
up and down swinging according to the style of sample fabric to be
produced.
[0003] (b) Description of the Prior Art
[0004] The rapid development in science and technology has brought
about a certain degree of improvement in the quality of life of
people, correspondingly, clothing material has tended towards
diversification, faster discarding of the old for new, increasing
difficulty to pin down demands of different groups of people, and
the differentiation between age groups is also becoming more and
more indistinct. Under such factors, textile mills (especially
those which provide design capability) are all equipped with sample
fabrics machines, which are used for design and sample work before
mass production of fabrics.
[0005] Sample fabrics machines of the prior art disclose: a base; a
plurality of heald frames, the heald frames being installed on the
base using separated means, and the heald frames are provided with
a plurality of healds, each of the healds being formed with a heald
eye, warp threads respectively serially pass through the heald
eyes, and different heights between the heald frames are used to
separate out a shuttle path between the designated warp threads; a
rapier tape chuck, which is provided with a crook, the rapier tape
chuck moves back and forth in the shuttle paths, and is used to
intercalate cut-off weft thread between the warp threads through
the shuttle paths; a color selector device, which is used to feed
the designated weft thread to an established region, and clutching
of the weft thread of the established region by the rapier tape
chuck is used to intercalate the weft thread, after being cut-off,
between the warp threads through the shuttle paths; a weft cutting
device, which moves back and forth in the established region, the
weft cutting device being used to implement cutting of the clutched
weft thread carried by the rapier tape chuck through the
established region; a steel reed, which is pin connected to the
base, the steel reed being provided with a plurality of reeds, the
warp threads pass through between the reeds, and the steel reed is
used to push the clutched weft thread carried by the rapier tape
chuck in the direction of the shuttle path, thereby causing the
weft threads passing between the warp threads to be mutually
contiguous with each other.
[0006] However, although the sample fabrics machines of the prior
art are able to automatically weave sample fabrics, nevertheless,
the heald frames use pneumatic cylinders to push upwards and
downwards to effect up and down swinging, and the pneumatic
cylinders using gas thrust as its power source results in slow
movement response of the up and down swinging of the heald frames.
Hence, the up and down strokes cannot be finely adjusted, making
fine control difficult. Moreover, gas thrust produces a large
amount of noise, and is thus considerably inconvenient in use.
SUMMARY OF THE INVENTION
[0007] Hence, in light of the shortcomings of the aforementioned
prior art, the inventor of the present invention, having
accumulated knowhow and manufacturing experience of a diverse range
of sample fabrics machines, attentively researched various methods
to resolve the shortcomings, which, following continuous research
and improvements, culminated in the design of a completely new
up-and-down swing mechanism for separated heald frames of a sample
fabrics machine.
[0008] The objective of the present invention is to provide an
up-and-down swing mechanism for separated heald frames of a sample
fabrics machine able to suspend up and down swinging of a portion
of heald frames using separated means.
[0009] According to the aforementioned objective, the up-and-down
swing mechanism for separated heald frames of a sample fabrics
machine comprises a plurality of regular arranged heald frames
fitted to a sample fabrics machine, wherein a lower end each of the
heald frames is connect to a fixed plate, and transmission arms are
respectively pivotal located on two sides of a lower end of each of
the fixed plates. A master drive and a slave drive are respectively
fitted within the sample fabrics machine corresponding to positions
of the two transmission arms. The master drive is driven by a power
device (such as: a servomotor), a swing arm is pivotal located to
the master drive, and a clutch is located between the power device
and the swing arm, thereby enabling the clutch to engage with the
swing arm or separate from the swing arm to cause up and down swing
or no swing thereof. Another swing arm is fitted to the slave
drive, and semicircular rows of teeth are respectively located on
corresponding ends of the two swing arms. The two rows of teeth are
disposed to mutually engage, thus, when the swing arm swings, the
other swing arm is actuated and swings in synchronization
therewith. Furthermore, the upper end of one of the transmission
arms is pin connected to one side of the lower end of the fixed
plate, and the lower end is pin connected to the other end of the
swing arm relative to the row of teeth, while the upper end of the
other transmission arm is pin connected to the other side of the
lower end of the fixed plate, and the lower end is pin connected to
the other end of the other swing arm relative to the row of teeth.
When in use, according to the style of sample fabric to be
produced, controlling a portion of the clutches to engage or
separate from the swing arms causes the two swing arms to swing or
not swing, which then drives a portion of the heald frames to cause
up and down swing or no swing thereof through the two transmission
arms, thereby weaving the required style of fabric.
[0010] To enable a further understanding of said objectives and the
technological methods of the invention herein, a brief description
of the drawings is provided below followed by a detailed
description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] The present invention relates to an up-and-down swing
mechanism for separated heald frames of a sample fabrics machine.
Referring to FIGS. 1, 2 and 3, which show an up-and-down swing
mechanism for separated heald frames of a sample fabrics machine of
the present invention, wherein a plurality of regularly arranged
heald frames 11 are fitted to a sample fabrics machine 10, a lower
end of each of the heald frames 11 is connected to a fixed plate
12, and transmission arms 13, 14 are respectively pivotal located
on two sides of a lower end of each of the fixed plates 12.
[0016] A master drive 21 and a slave drive 22 are respectively
fitted within the sample fabrics machine 10 corresponding to
positions of the two transmission arms 13, 14. The master drive 21
is driven by a power device (such as: a servomotor) (not shown in
the drawings), a swing arm 211 is pivotal located to the master
drive 21, and a clutch 23 is located between the power device and
the swing arm 211, thereby enabling the clutch 23 to engage with
the swing arm 211 or separate from the swing arm 211 to produce up
and down swing or no swing thereof.
[0017] Another swing arm 221 is fitted to the slave drive 22, and
semicircular rows of teeth 213, 223 are located on corresponding
ends of the two swing arms 211, 221 respectively. The two rows of
teeth 213, 223 are disposed to mutually engage, thus, when the
swing arm 211 swings, the other swing arm 221 is actuated and
swings in synchronization therewith. Furthermore, the upper end of
the transmission arm 13 is pin connected to one side of the lower
end of the fixed plate 12, and the lower end is pin connected to
the other end of the swing arm 211 relative to the row of teeth
213, while the upper end of the other transmission arm 14 is pin
connected to the other side of the lower end of the fixed plate 12,
and the lower end is pin connected to the other end of the other
swing arm 221 relative to the row of teeth 223.
[0018] Hence, according to the style of sample fabric to be
produced, controlling a portion of the clutches 23 to engage or
separate from the swing arms 211 within a period of time (as
depicted in FIGS. 2, 4) causes the two swing arms 211, 221 to swing
or not swing, which then drives a portion of the heald frames 11 to
cause up and down swing or no swing thereof through the two
transmission arms 13, 14 within a period of time, thereby weaving
the required style of fabric.
[0019] Referring again to FIGS. 1, 2 and 3 together with FIG. 4,
each of the clutches 23 is connected to the power device, thereby
enabling the power device to drive each of the clutches 23 in
synchronous rotation. A protruding piece 231 is located on each of
the clutches 23, a circular arc-shaped fixed plate 215 is pivotal
located on the swing arms 211 corresponding to the positions of the
protruding pieces 231, and a clasp groove 216 is provided on an
inner side of the fixed plates 215 to correspond with the
protruding pieces 231, thereby enabling the protruding pieces 231
to insert into the clasp grooves 216. Hence, when the power device
drives the clutches 23 to effect synchronous rotation thereof, then
the protruding pieces 231 inserting into the clasp grooves 216
enable the power device to indirectly drive the swing arms 211 and
cause up and down swing thereof.
[0020] Referring again to FIGS. 1, 2, 3 and 4, a selector 15 is
located on the sample fabrics machine 10 corresponding to the
position of the fixed plate 215 of each of the swing arms 211, and
a push rod 151 is located on each of the selectors 15 above each of
the fixed plates 215. The selectors 15 are electrically connected
to a control circuit (not shown in the drawings) of the sample
fabrics machine 10, and the selectors 15 are controlled by the
circuit control, thereby enabling the control circuit to control
the selectors 15 to extend downward a portion of the push rods 151
within a period of time according to a set program, and thus cause
the push rods 151 to actuate and move the fixed plates 215 and
induce the protruding pieces 231 of the clutches 23 to separate
from the clasp grooves 216 of the fixed plates 215, thereby causing
the clutches 23 to run idle and be unable to drive the swing arms
211 and effect up and down swing thereof, which causes the swing
arms 211 to stop swinging within that period of time, and
simultaneously suspends up and down swinging of the corresponding
heald frames 11. Accordingly, controlling suspension of up and down
swinging of a portion of the heald frames 11 is used to enable the
required fabric to be woven.
[0021] In conclusion, the up-and-down swing mechanism for separated
heald frames of a sample fabrics machine of the present invention
is assuredly provided with an innovative structure not found in the
prior art. Moreover, no similar products have been seen in any
publication or in the market; the present invention is thus
provided with undoubted originality. In addition, the present
invention is provided with unique characteristics and functionality
that are without comparison in the prior art. Hence, the
incomparable advancement of the present invention clearly complies
with the essential elements as required for a new patent
application. Accordingly, a new patent application is proposed
herein.
[0022] It is of course to be understood that the embodiments
described herein are merely illustrative of the principles of the
invention and that a wide variety of modifications thereto may be
effected by persons skilled in the art without departing from the
spirit and scope of the invention as set forth in the following
claims.
