Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a spinning machine equipped with a ring traveler mechanism that can spin yarn with less fuzz than conventional yarn.

(Prior technology) Air jet looms, which use air force to drive weft yarns, have high productivity, so the number of equipment has been increasing in recent years, and their occupancy in looms is gradually increasing. However, when the ffff loom is weaving, the warp and warp threads for weaving,
In particular, because the weft yarns are exposed to high-pressure air, the fluff of the finished greige is slightly higher than that of other loom-fried greige (inevitably, the yarn is superior in terms of yarn quality, especially fluff, than raw yarn for other looms). Be requested.

Naturally, gas firing or stronger sizing can be considered as measures to reduce the fluff of spun yarn, but the former has the disadvantage of high manufacturing costs, and the latter is a temporary problem caused by glue adhesion. Therefore, it cannot be a fundamental method for improving thread quality.

As a technology to solve these problems, Tokuko Sho 52-6841
In No. 6, a spiral fluff suppressing body is installed on the running path of the spun yarn in a heated winding machine such as a spinning machine or a twisting machine, and the spun yarn is brought into contact with the spiral circumferential groove of the spinning machine. A method has been proposed to reduce the fluff of the yarn and improve the quality of the yarn itself.

(Problems to be Solved by the Invention) The above method basically makes it possible to spin yarn with less fluff by adding a simple device while using the conventionally known spinning mechanism as is. Although it is an excellent invention in many respects,
The fluff of the resulting yarn does not fully meet the requirements of the air jet room, and it is difficult to install a helical body with a complex shape in the atmosphere around the spun yarn, which is relatively dusty. This is not desirable in terms of operation, and poses a major practical problem in this respect.

The present invention aims to solve these problems and provides a novel device capable of producing yarn with a low fuzz that is suitable for air jet looms at low cost using a simple mechanism.

(Means for Solving the Problems) The present invention has the following configuration in order to solve the above object. That is, it is a spinning machine equipped with a ring traveler mechanism, in which an endless tape running in a direction across the spun yarn is provided on the yarn travel path between the bottom front roller and the snail wire, and the working surface of the tape is used as the spinning machine. This is a configuration characterized in that the threads are brought into contact with each other and run in the direction in which the twist of the spun yarn is added.

(Function) The spinning machine according to the present invention brings the spun yarn immediately after exiting the front roller into contact with an endless tape running in a direction transverse to the ring traveler with the fuzz on the surface of the spun yarn facing down. Since the yarn is twisted in the same direction as the twist coming from the twisting mechanism, the fluff on the surface of the yarn is twisted into the yarn structure (pongee), creating a permanent fluff retention instead of a temporary fluff retention like gluing. This makes it possible to spin yarn with significantly less fluff than conventional spun yarn that does not run an endless tape. The apparatus of the present invention will be specifically explained below with reference to embodiments shown in the drawings.

(Example) In FIG. 1 showing the arrangement position of each mechanism constituting the device of the example, (1) is a supply roving unwound from a Shinomaki (not shown); As is well known, the roving rod (21) includes a trumpet (3), a pair of rollers (4) consisting of an actively rotating bottom pack roller and a top back roller that rotates drivenly in pressure contact with the bottom pack roller, and an actively rotating bottom pack roller (4). A pair of rollers (5) of the top middle roller which comes into pressure contact with this n through the bottom middle roller and the upper and lower aprons and rotates as a result, and the bottom front roller of I&I polar rotation and the top front roller which comes into pressure contact with this n and rotates as a result. The fleece passes through a pair of rollers (6) in sequence and becomes a fleece (not shown) that receives the drafting action by a pair of different rollers.Next, the fleece exits the bottom front roller field. Immediately after, it is untwisted from the ring traveler mechanism (8), receives the n-S twisting force transmitted through the snail wire (b), becomes a spun yarn (9) of twisted yarn, and is transferred to the bobbin Oq.
Wind it up.

In the known spinning apparatus, the apparatus according to the embodiment of the present invention has the following features:
As shown in Figure 1, a flat endless tape (b) extending from one end of the machine base to the other end is connected to an n-minute beam (b).
It is installed on the beam 03k and the working surface α4 (shown in FIG. 5) of the endless tape (6) is connected to the spun yarn (
9) is supported in parallel to the direction of travel of T and in contact with T. However, the endless tape 0υ is the machine beam (
2) engages with a drive pulley 05 provided at the end, and is rotated by the motor ae to actively travel in the direction indicated by the upper arrow in FIG.

To explain the moving direction of the endless tape (b), in this example, the spun yarn (9) has a left-handed twist, that is, 2
Since the twist is applied, the bobbin αQ and the traveler of the ring traveler mechanism (8) in the state shown in FIG.
is rotated in the direction of arrow 2, and the spun yarn (9) is also twisted in the direction of arrow 2 shown in Figures 2 and 8. In this state, the endless tape (B) must be run on the back side of the spun yarn (9) when viewed from the front side of the paper in FIG. 1, and brought into contact with the spun yarn (9) from the back side.

Further, to explain the structure of the endless tape α, as shown in Fig. 6, urethane tape is bonded to both sides of the surface of the tangential tape aη, and a felt wire is bonded to the inside of the urethane tape to form a three-layer groove structure. It forms an action surface α◆.

The tangential tape αη has high strength and stable properties, allowing it to run well over a long period of time, and the urethane tape (1) has a spun yarn (9) that contacts the endless tape (2). ), and protects the felt Q'J in the center from wear and tear.It also has a good frictional force for twisting the fuzz of the spun yarn (9) from the felt 0 old. The endless tape (B) is made up of the tangential tape αη, the urethane tape (G), and the felt Ql band. There is.

Next, the configuration of the guide pulley (to) that adjusts the contact force and contact angle between the endless tape αp and the spun yarn (9) will be explained with reference to FIG. Said guide pulley (to)
is the tape (6) at the extending position of the endless tape αυ.
A plurality of yarns are arranged at predetermined intervals to prevent meandering, and by adjusting the distance from the spun yarn (9) in the far and near directions, the contact pressure with the yarn (9) can be adjusted, and at the same time accurate running can be achieved at all spindles. It serves the purpose of maintaining against. In short, the running friction force and contact pressure between the spun yarn (9) and the endless tape αη are determined by adjusting the rotational speed of the motor α and the installation position and installation angle of the guide pulley (2) using an inverter. Ru. Note that these running frictional forces and contact pressures are naturally set depending on the spinning material, count, and fluffing condition.

The apparatus according to the embodiment of the present invention has the above-mentioned configuration, and the driving state thereof will be explained next.

It passes through the conventional foot area where the endless tape αη is not placed and receives the twisting action from the ring traveler mechanism (8) to become the spun yarn (9). As shown in Figure 8, the bottom front roller (
7) and the spun yarn (9) between the snail wire &])
is brought into contact with the endless tape (B), and the fluff of the spun yarn (9) is pressed by this and receives a twisting action while being pressed, and is twisted into the yarn body. .

To explain this state in more detail with reference to FIG. 185, the spun yarn (9) is spun at a predetermined yarn speed V, and in this state, the spun yarn (9) is The heating turning force is applied by the twisting force from (8). A contact pressure P from the endless tape αp is applied to this spun yarn (9), while a frictional force X is applied from the urethane tape on the action surface a4 of the endless tape αυ and the felt α. As a result, the fluff (1) is effectively twisted into the spun yarn (9) by the resultant force of the frictional force X of the endless tape αυ with a low contact pressure P, thereby significantly reducing the fluff field.

In the examples shown in Fig. 1 and Fig. 8, the endless tape α was run in an anhydrous state.

If you want to add yarn processing other than fluffing, such as warming or oiling, connect the endless tape 4 to an appropriate liquid replenishment mechanism (support) as shown in Figure @4, and adjust the working surface of the endless tape αη. If a◆ is kept constantly moist,
Various liquid treatments can be performed at the same time as fluff binding. Note that it is not necessary to install the fluid replacement mechanism 4 on all the spindles of the machine (it is possible to select one for each spindle at a predetermined interval, or one per machine, etc.).

Specific example Material: 100% cotton, supplied roving weight: 110 gelens/15 yards, spinning count: 80'8 (English style), number of twists: 21.7 T/inch,
Total draft 24.6 times, spindle rotation speed 120
Under the spinning conditions of 0 OR/M, a spinning speed of 15.5772/min, and an endless tape running speed of 80 m/min, fluffing was performed using the apparatus shown in Figure 8 and Factor 4. The results are shown in the table below.

Fuzz measurement Number of pieces The measurement was made using Shikishima Boseki Co., Ltd. model F-4NDEX'I.
This was done using a fluff measuring device 'EI9'I'EiR.

As shown in the table above, by using the device of the present invention, it is possible to obtain a yarn with several orders of magnitude less fuzz compared to conventional spun yarn, and the number of fuzz is 8 at the precision of the measuring device J3117/m.
If the number is 0 or less, preferably 10 or less, it can be used as a yarn for air jet looms that is sufficiently exposed to light.

(Effects of the Invention) As mentioned earlier, the present invention basically uses a conventional spinning mechanism, and uses a simple mechanism in which a traveling mechanism for a fluff suppressing belt is added to the spinning mechanism to produce spinning with extremely low fluff. It is possible to spin a single yarn, and the problems in the prior art described in the opening 6 can be completely solved.
