Abstract

PURPOSE:To prevent occurrence of abnormal yarns or yarn breakage caused by yarn sway, etc., while suppressing an extreme increase in height of equipment and interval interval between spindles, etc., by installing respective roll parties of a pair of Nelson rolls in the horizontal direction and further the other roll parties in the vertical direction. CONSTITUTION:Respective roll parties (1a) and (2a) of a pair of Nelson rolls (1a), (1b), (2a) and (2b) rotating in the same direction are tilted in the horizontal direction and the other roll parties (1b) and (2b) are tilted in the vertical direction. In winding a yarn (Y) around the rolls, a sufficiently large yarn pitch obtained by interaction of both rolls is ensured without occurrence of yarn sway, etc., even if the tilting installation angle of the rolls is reduced.

ている。(0) Prior Art Conventionally, without subjecting synthetic fiber threads to any treatment such as transfer, a method has been adopted in which the threads are wound a plurality of times around a pair of rollers rotating in the same direction, so-called flannel rollers, and then heated. In this Nelson roller device, one way to ensure the yarn pitch of the yarn wound multiple times is to install one roller with an upward and downward slope (for example, Utility Model Publication No. 52-3177
8 Fig. 1, Fig. 2〉 (hereinafter referred to as conventional method A) Alternatively, a method in which the tips of both rollers are installed horizontally and tilted in the left-right direction so that they approach each other (for example, Japanese Utility Model Publication No. 54-378)
60 (Fig. 3) (hereinafter referred to as conventional method B), etc. have been proposed.

、加熱斑等の糸質異常を派生することになる。In order to suppress vibrations associated with increased size, the conventional motor direct-coupled type, in which the roller was attached directly to the motor shaft, is now becoming mainstream, with the motor 1111 type, in which the motor shaft is coupled to a dedicated bearing box that supports the roller, using a coupling. be. However, in such a motor-separated type, the length of the entire roller unit consisting of the roller, bearing box, and motor increases dramatically, and in conventional method A, the roller unit is installed tilted up and down, which increases the height of the entire device. In particular, in direct spinning and drawing equipment in which multiple Nelson roller devices are stacked, not only does the equipment cost become high, but also the threading has to be carried out at high places, which poses a major safety problem. Ta. In addition, in conventional method B, as the length of the entire roller unit increases dramatically, the width from side to side also increases, and the distance between the spindles of consecutive equipment becomes wider, which also causes a rise in equipment costs. This made the operation monitoring work inefficient. Furthermore, in order to improve productivity, it has become common practice to process multiple threads at the same time, and recently four threads have been processed simultaneously.
A method has even been put into practical use to transfer and process a book or eight threads at the same time (for example, see the front page of the Nikkei Sangyo Shimbun dated November 13, 1985), and in order to increase the thread pitch on the flannel roller, the inclination of the roller is necessary. The angle has become increasingly large. Simply increasing the inclination angle of the rollers not only increases the overall height of the equipment and increases the spacing between the spindles for the same reason as described above, but also increases equipment costs. Thread quality abnormalities such as stretching spots and heating spots will result.

However, it is an object of the present invention to provide an excellent device that prevents the occurrence of abnormal yarns due to yarn wobbling or the like, or process abnormalities such as yarn breakage, while suppressing the height of the equipment, the distance between spindles, etc. from becoming extremely large.

The vertical swing base 4 can be attached to the mount frame (not shown) so as to be rotatable up and down by the taper piece 9 and the pivot 10. However, the taper angle of the taper piece 9 can be replaced with a part having a preset angle as appropriate. Here, the left and right swinging base 3 and the top and bottom neck shooting base 4 are a pair of Nelson rollers 1a.
, 1b, the left roller 1a is installed to be inclined horizontally to the right when viewed from the front, so that the included angle in the horizontal direction between the axes of the shafts 1b is 01° and the intersecting angle in the vertical direction is ψ1, and the right roller 1b
It is installed so that it can be viewed from the front and is tilted vertically upward. By inclining the rollers 1a and 1b in this way, the included angle θ1 in the horizontal direction can be reduced to approximately half the included angle required in conventional method B, and the intersecting angle Φ1 in the vertical direction can also be reduced to that in conventional method C1. This makes it possible to reduce the angle to approximately half the required crossing angle. Similarly, the upper pair of Nelson rollers 2a and 2b each have an included angle in the horizontal direction of θ2. Both are installed at an angle that is approximately half the inclination angle required in the conventional method so that the vertical crossing angle is ψ2 (not shown). Note that the angle θ1.2. ψ1.

される。Next, the effect will be explained. In the figure, two sets of Nelson rollers 1a, 1b and 2a, 2b are heated by an appropriate means such as an electric heater or a heating medium, and are rotated at high speed clockwise when viewed from the front while keeping the roller circumferential surface at a predetermined temperature. ing. The yarn Y brought from the lower left is guided by a pair of Nelson rollers at the lower part, from the upper surface of the left roller 1a to the upper surface of the right roller 1b, and then to the right half of the left roller 1a. It is wound around both rollers 1a and 1b several times in this manner, and then sent out to a pair of upper Nelson rollers. Similarly, for the upper pair of Nelson rollers, the threads Y are both 2a and 2a.
After being wound several times around b, it is sent out to the upper left, which is the next step. When winding yarn around the Nelson roller device in this way, even if the inclined installation angle of each roller is small, the yarn pitch l) +, p2 obtained by the interaction of both rollers
is ensured to be sufficiently large, and occurrence of yarn wobbling etc. is also prevented.

が好ましい。In this embodiment, in a pair of Nelson rollers, the left roller is tilted rightward, and the right roller is tilted upward, but the combination is not limited to this. For example, the left roller is tilted downward, and the right roller is tilted upward. Almost the same effect can be obtained by tilting to the left. However, of the two rollers that make up the Nelson roller pair, the first roller (the roller on the a side in this example), which should first take up the yarn and send out the yarn last, should be used to move the yarn in and out as much as possible. It is preferable to install the roller in such a way that the axis of the roller is perpendicular to the direction, since the stability of thread guidance is better, and therefore it is preferable to install the roller at an angle in the direction of this embodiment.

ことができる。In addition, although this embodiment shows the case where the yarn Y is run from the bottom to the top, when the thread Y is run from the top to the bottom or in the horizontal direction as shown in FIG. A similar effect can be achieved by installing one of the rollers horizontally and the other vertically.
