Description

[Detailed explanation of the invention] This invention is based on a bristle comber (abbreviation for silk spinning and worsted comber) that uses a rotating comb cylinder with a large number of rows of combs (throat plate) and coarse needle density. The object is to improve the combing action of the sliver by reciprocating the cylinder in its axial direction.

In conventional bristle combers, the sliver gripped by nippers is combed by rotating a comb cylinder with ten or so rows (previously 18 rows) of combs attached to the half ramps of the comb cylinder. The needle density in the first row of the comb is about 4 needles/crF1,
The needle density in the last row (18 o'clock, 1 o'clock) is extremely high, 29 needles/crrI.

The gap between the upper ends of the needles of a comb with a high needle density is somewhat wide, but it becomes noticeably narrower as it approaches the base, and the needles are also very long. Alternatively, when worsted slivers are combed, contaminants such as short fibers, nodules, and pieces of shaft (silk only) are left between the needles of each comb.

In particular, the fibers of silk spun sliver have a fineness of 1 denier and are extremely long.

In addition, some of the sericin has melted and there are quite a lot of fibers that are attached to each other, so even if the brush roller installed below the comb cylinder rotates once, it will not completely remove the foreign matter caught in the gaps between the needles of the comb cylinder. It is extremely difficult to remove it.

Therefore, as the operation of the bristle comb continues,
Gradually more short fibers and foreign matter remain in the needle gap.

Therefore, the fibers in the sliver are forced into the narrow needle gap and combed, so long fibers are also pulled out from the sliver.
This method has the disadvantage that not only the fibers are often cut and tangled, but also the combing action is poor and a comb sliver with many foreign substances is produced.

This invention was made for the purpose of improving the above-mentioned conventional drawbacks, and will be explained in detail below with reference to the drawings.

As shown in FIG. 1, a helical spring 5 whose strength can be adjusted is inserted into the shaft 4 between the shaft bearing 2 attached to the frame 1 of the bristle comber and the comb cylinder 3. An umbrella-shaped cam 6 and a wide gear 7 are fixed to the end of the umbrella-shaped cam 6, and a recess 8 is formed in a part of the slope of the umbrella-shaped cam 6. is fixed to the support frame 10 of the frame 1, and while rotating the shaft 4 to which the comb cylinder 3 is fixed, it is possible to reciprocate in the axial direction. This is a comb cylinder device for fine hair combing, characterized in that the needle density of these combs 11 is made 10 to 20 coarser than conventional ones, and 12 is a boss for fixing the comb cylinder 3 to the shaft 4, and 13 is a boss. A screw fitted to the shaft 4, a nut 14 fitted to the screw 13 to adjust the strength of the spring 5, and a gear 15 driven by a drive mechanism (not shown) connected to a motor (not shown). It is.

Note that the recess 8 formed on the slope of the umbrella-shaped cam 6 corresponding to the center angle of the half-wrap of the comb cylinder 3 is gradually deepened in the rotational direction of the umbrella-shaped cam 6 to 10 to 25 peaks.
-・-The slope becomes gradually shallower beyond the position of the slope corresponding to the central angle of the flap.

Alternatively, the depth of the recess 8 on the slope of the umbrella-shaped cam 6 corresponding to the central part of the central angle mentioned above may be set to between 5 and 15, and the depth may be made gradually shallower at the positions of the slope corresponding to the first and second half central angles. .

The present invention is constructed as described above, and has the following functions and effects.

When the gear 15 is rotated by a drive mechanism (not shown) from a motor (not shown), the wide gear 7 rotates, causing the shaft 4 to rotate, and the umbrella-shaped cam 6 fixed to the shaft 4 to rotate.
and the comb cylinder 3 rotate at the same predetermined speed.

Furthermore, as the umbrella cam 6 rotates, the recess 8 formed on the slope of the umbrella cam 6 also rotates.

As the umbrella-shaped cam 60 rotates, the truncated-conical roller 9 rolls on the slope or recess 8 of the umbrella-shaped cam 6. However, since the axis of the truncated-conical roller 9 is fixed to the support frame 10 of the frame 1, the truncated-conical roller 9 rolls on the slope or recess 8 of the umbrella-shaped cam 6. When the roller 9 rolls from the slope of the umbrella-shaped cam 6 to the recess 8 and reaches the deepest part of the recess 8, the comb cylinder 3 slides in the opposite direction to the wide gear 7 due to the elastic force of the helical spring 5. move.

Its sliding distance is 10-25 plates.

When the combing action of the front end of the sliver by all the 26 to 32 rows of combs 11 is finished, the recess 8 gradually becomes shallower, and the comb cylinder 3 is moved toward the wider gear 7 due to the elastic force of the helical spring 5. It slides back to its original position.

In addition, the depth of the recess 8 at the center of the slope of the umbrella-shaped cam 6, which corresponds to the center of the center angle of the half ramp of the comb cylinder 3, is 5 to 15 mm, and the depth of the recess 8 is 5 to 15 mm. When the depth of the recess 8 is gradually made shallower,
The truncated conical roller 9 forms a recess 8 on the slope of the umbrella cam 6.
The combing action of the front end of the sliver by all the combs 11 in the 26th to 32nd rows of the comb cylinder 3 is completed while the comb cylinder 3 is rotating, and the comb cylinder 3 is rotating in its axial direction. It reciprocates ~15mm.

In order to make the elastic force of the spring 5 a predetermined value,
Adjust by rotating the nand 14 fitted with the screw 13.

Even if the comb cylinder 3 reciprocates 10 to 25 μ in the axial direction, the width of the gear 7 at the end of the shaft 4 is reduced by the drive gear 15.
If it is made wider by 10 to 25 mm, there will be no problem in meshing gear 7.15.

It is sent out from a feed roller (not shown) and passed through a nipper.
When the front end of a sliver (not shown) gripped by a sliver (not shown) is combed by the needles of the 26th to 32nd rows of combs 11 attached to the flap, as the comb cylinder 3 rotates, the first The needles of the combs 11 in the row pierce the front end of the sliver, and the comb cylinder 3 rotates further to
When the needles of the row of combs 11 penetrate the front end of the sliver, the comb cylinder 3 gradually slides in the opposite direction to the gear 7 according to the rotation of the recess 8 in the wound surface of the umbrella cam 6.

Therefore, the position where the fibers at the front end of the sliver gripped by the nippers are pierced by the needles of the comb 11 in the second row is somewhat in the opposite direction to the gear 7 from the position where the fibers at the front end of the sliver gripped by the nippers are pierced by the needles of the comb 11 in the first row. It shifts.

Similarly, the position of the front end fibers of the sliver pierced by the needles of the third row of combs 11 of the comb cylinder 3 is also opposite to the gear 7 from the position of the needles of the second row of combs 11. It shifts slightly in the direction.

Similarly, the position of the fibers at the front end of the sliver that are pierced by all the combs 11 of the comb cylinder 3 is determined by the depth of the recess 8 in the slope of the umbrella cam 6.
shift in the opposite direction.

Therefore, the fibers in the front end of the sliver are transferred to the comb cylinder 3
Each row of the combs 11 is diagonally contacted with the needles of the combs 11, and receives a □ combing action.

Alternatively, if the recess 3 is formed on the slope of the umbrella-shaped cam 6 corresponding to the central angle of the half ramp of the comb cylinder 3,
Since the comb cylinder 3 reciprocates in the axial direction while the comb cylinder 3 is combing, the position of the fibers of the sliver pierced by the needles of all the combs 11 is bent in a dogleg shape, and the combs 11 of each row contact with the needle.

Therefore, when the needles of each row of combs 11 comb the front end of the braided sliver (abbreviation for spun silk or worsted sliver) due to the rotation of the comb cylinder 3, the frictional force between the needles and the fibers increases significantly.

For this reason, each fiber at the front end of the assembled sliver is strongly squeezed and cauled, so that the fibers attached to each other by molten sericin are easily separated.

Therefore, the fibers of the assembled sliver are not only opened well, but also foreign substances attached to the fibers are easily separated from the fibers.

Moreover, due to the reciprocating movement of the comb cylinder 3, the needles of the comb 11 in each row stick into the slightly shifted fiber positions of the assembled sliver, making fiber separation very good, making it extremely easy to open the fibers and remove impurities. Well done.

In addition, in the knitting hair comb of the present invention, the density of needles in each comb 11 of the comb cylinder 3 is 10 to 20 coarser than the conventional one (4 needles/crn to 23 needles/-), but the total number of comb rows is Since the number of rows is 26 to 32, which is more than the conventional 18 rows, the frictional force between the needles of each comb 11 and the fibers of the braided sliver due to the reciprocating motion of the comb cylinder 3 increases significantly, compared to the case of the previous knitting comb. A very good combing effect is obtained.

In addition, since the density of the needles of each comb 11 is set to be in the range of about 4 needles/cm to 23 needles/cm, which is 10 to 20% coarser than the conventional one, short fibers are sandwiched between the needles of each comb 11.

Nodules, calyx pieces (impurities such as silk only) are removed by brush rollers (
(not shown) can be easily removed by one rotation.

Therefore, even if the knitting hair comber continues to operate for a long time, there is almost no foreign matter remaining in the gap between the needles of each comb of the comb cylinder. There is a remarkable effect that the risk of occurrence of breakage, cutting, etc. is extremely reduced, and the amount of contaminants in the produced comb sliver is significantly reduced, and comb sliver of good quality can be obtained.

If the quality of the produced comb sliver is limited to the quality of conventional fine comb slivers, the braiding comb sliver of the present invention can be improved by increasing the supply amount of the braided sliver, increasing the rotational speed of the comb cylinder, etc. It also has a remarkable effect, such as being able to increase production by about 50% compared to conventional hair combing.

Even though nine needles are used in each row of combs, using flat needles provides a better cursing effect due to the reciprocating movement of the comb cylinder in its axial direction.

Also, even if you use a unicomb with a metallic wire attached in place of the comb of a regular needle in the first half segment of the half-wrap, the second half segment of the half-ramp will have 13 to 16
Because it uses a row of combs and more regular needle combs than before,
Another advantage is that the noils on each comb can be easily removed and a good comb sliver can be obtained.
