Abstract

PURPOSE:The titled spinning frame capable of increasing extremely the number of spindles in a spinning frame with the same length of frame base, obtained by making each spinning unit wherein plural spindles are corresponded to one draft mechanism. CONSTITUTION:Plural sets of the draft mechanisms 4 are arranged in parallel along the length direction of the frame base of a spinning frame, and one set consists of the back rollers 1, the middle aprons 2 and 2, and the front rollers 3 and 3. In the front of the draft mechanism 4, the two spindles 5 and 5a corresponding to it are attached to two lines of the spindle rails 6 and 6a set along the length direction of each frame base, and they are positioned in the front and rear direction against the draft mechanism 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel ring spinning machine. More details relate to the structure of ring sheath spinning, which greatly improves productivity per machine.

There has been a strong desire to improve the productivity of ring-type spinning machines, and one measure to counter this has been to increase the rotational speed of the spindle.

However, this method is accompanied by an increase in the speed of the trapper, resulting in increased spinning force and yarn breakage due to traveler flying (j
This not only deteriorates the operability but also has a large impact on the quality of the yarn, such as fluffing due to increased ballooning. Furthermore, consumption 1b: There are fatal flaws that go against the demands of the times for energy conservation, such as the power increasing dramatically at a rate that exceeds the rate of increase in production.
It is said that the limit is 6,000 rpm.

On the other hand, add the number of spindles per spinning machine.

Attempts have also been made to lower the machine cost per bell and increase the production volume per unit (7 to 800 per unit instead of the usual 400 per unit).
F, Al spinning machines based on the gtZ machine have also appeared. However, in this ff1t4, the waiting length is inevitably long, so it is necessary to replace the building that houses it, or to take measures against twisting of the shaft, rollers, etc. installed along the length of the machine. Ancillary or unavoidable increases in equipment costs, such as making it a necessary nephew, are often not very beneficial overall.

The present invention has been made in view of the drawbacks of the prior art.
By increasing the number of spindles while keeping the size at 5, and by sharing the single 1-noft structure with two spindles (thereby increasing the production volume per one spinner), The purpose is to reduce the production cost of fine spinning by decreasing the setting of the pint loop per spindle (INi %f), thereby lowering the co-cost of production.1 (11

If necessary, it is advisable to use a separate collector (not shown) for each braided yarn between rollers to prevent interference between the two yarns.

It is wound up. In the figure, reference numeral 12.12a is an ammy node ring for ballooning the yarn when twisted with a force of 11.

7. Without paying sufficient consideration to size, etc. )There is a need. Snell wire all cars 1. The reason for providing the second two stages is that the passages 1 to γIJC of the spun fleece that fall on the two sides of the front roller 3 (bottom 111) are divided into 7iitt K for each fleece. Therefore, the yarn splicing work is made easier, the spun yarn quality VC is greatly influenced by the fleece angle, that is, the contact angle of the fleece with the roller 3. If there is no wire, the first Snell wires 9, 9a may be omitted.

Regarding the famous rollers of draft equipment fat, see 1'
In order to strengthen the gripping force on the Il yarn, it is necessary to increase the pressure by 1 μml at least 50 times more than the 9-9 cross on one roving yarn. Due to the breakage of one of the yarns, the spinning face IJ -
1- In order to eliminate the risk of the pneumatic clearer 13 hitting the fleece, an opening [-1 part of the pneumatic clearer 13 is provided for each fleece directly under the front roller 3, and the position of the eye and the heel are set higher than in the normal case. Slightly) It is desirable to get closer to IJ-S and strengthen your influence.

Furthermore, an appropriate roving knitting device 14.14a that is linked with thread breakage detection means (not shown) is provided in front of the thread breakage unit 14, and the braided thread is slit at the same time as the thread breakage, and the braided thread is fed. It is desirable to stop.

In the embodiment of the diagonal top, two rows of spindles are provided in front of each draft mechanism, stacked in the front and back direction, in consideration of the operability of doffing, thread E4:i', and ginning. If this point is agreed upon, there is no particular restriction on the number of spindle rows, and it is possible to arrange three or more rows of spindles, and the total number of spindles per machine can be further increased without substantially increasing the total length of the machine. It can increase. In addition, 1 sea urchin spindle 5 shown in FIG.
* It is also possible to provide two rows of S a k shifted in the left and right direction by the distance between the two fleeces.

As described in detail, in the present invention, one unit of draft device is provided for all two or more spindles, so in a spinning machine with the same frame length, the number of spindles is 11Jc/
