JPS5881630A - Flyer presser for roving frame - Google Patents

Abstract

PURPOSE:A weight of a high density is fitted to make the gravity center of the presser position on the side opposite to the presser paddle with regard to the rotation center to increase the pressure of the presser, while the presser is kept light in its weight and permit the increase in the weight of the wound roving. CONSTITUTION:A rod-like weight 19 is fixed to the long hole 7a bored in the presser-supporting lever 7. The weight 19 is made of a material larger in density than the lever 7 and fixed to the position as far as possible from the axis line A on the side opposite to the presser paddle 17 with regard to the axis line A, i.e., the center of rotation. The centrifugal force caused by the rotation of the flyer around the flyer spindle 21 allows the presser paddle 17 on the top end of the presser arm 13 to press the bobbin or the roving wound around the bobbin strongly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flyer pretuna for a roving frame, and a flyer pretuna for a roving frame, which is manufactured from a material with relatively low specific gravity such as a special aluminum alloy, a special light alloy, or ceramic. When the flyer of the rover rotates, nine flyer grenas rotatably supported by centrifugal force are rotated by centrifugal force, and nine nore and noudle are formed at the tip of the flyer. □ To wind the roving at high speed, it is necessary to reduce the weight of the pre-roller so that the flyer can rotate at high speed. In other words, in a case where the lower end of the leg O is open, the leg is deflected by the centrifugal force generated by rotation, and depending on the amount of compensation, it may have an adverse effect on the spinning.Therefore, the amount of ζ deflection In order to reduce the flyer leg o from the viewpoint of material mechanics,
In addition, reducing the weight of the preflexor arm and Δ dollar at the tip of the hollow leg is also effective in reducing the amount of deflection. Also, the amount of roving wound on the bin can be reduced. Since K increases, it is better to have a larger pressure force on the 79 ear pressure to prevent winding barrel warping.However, if the weight of the prefusa is simply reduced and the centrifugal force acting on the 90 decreases, the pressure on the prefusa decreases. The desired size could not be achieved, and it was difficult to cope with the increase in the amount of roving wound.

On the other hand, in order to make it possible to wind the O roving oyam around the bobbin, it is necessary for the flyer oli1 to immediately contact the roving pin and press it against the roving YtW bin. In order to achieve ζO, it was previously believed that it was necessary to reduce the weight of the pretuna and improve responsiveness.

As mentioned above, from the viewpoint of high-speed winding and automatic winding OIi, it is preferable to reduce the weight of the pre-tuna, but on the other hand, from the perspective of increasing the amount of winding, reducing the weight of the pre-tuna has traditionally been considered undesirable. mourning.

In view of this situation, the present invention has been developed by reducing the weight of pre-tuna.
Jin and T provide a flyer press for a revolving spinning machine that is capable of increasing the winding amount by increasing the winding amount while maintaining the high-speed winding effect and automatic winding effect. The present invention will be described in detail below with reference to embodiments of the invention shown in the accompanying drawings.In the first embodiment shown in FIGS. 1 to 5, a flyer IFi, a hollow redder 3 and a Special light alloys such as Kalantare, Da 5, special Al J-rim alloys, or Cera 1
．． It is manufactured from the # family, which has a relatively low specific gravity. Ho fourre! 3 also includes special aluminum alloys, etc.
Pre made from materials with relatively low weight, such as S light metal, or Sera 1, Yu, etc.! 1. Support rod 7 is pre-supported, and support bin 9.
11], and is rotatable about the rotation center of the shaft 11At of the placer support bins 9, 11.

The pre-support rod 7 is composed of a pre-support arm 13 and a support rod main body 1s, which are located at the front and rear of the axial line arm, which is the center of fibrillation. And, at the tip of the pre-sa arm 1340, there is a pre-pre that presses the roving to be wound on the -bin or I-bin.
A mother dollar 17 is formed.

As shown in Fig. 4 and Fig. 5, a long hole 7s in the vertical direction of the rod 70 is bored, and a rod-shaped weight member 19 is glued, screwed, or cast into the long hole 7aK. Identified. ζ This is made of a material with a specific gravity larger than 7, such as steel, copper, lead, etc., for example. A stick? Instead of the weight member, a long hole 7aiC mercury may be inserted and the upper part Kt& of the weight member may be fixed.
The position should be on the opposite side of the front and sabador and as far away from the axis as possible.

In FIG. 1, reference numeral 21 indicates a flyer spindle A-, which represents the center of rotation of the flyer, and reference numeral 23 indicates a spindle attached to the lower end of the caranta relada 80.

The flyer pre of this example appears from the above-mentioned configuration.

At time t, the center of gravity Gl of the pre- and sa-arms 130, which extends in one direction from the axis M, which is the center of rotation, is located at the pre-g'' paddle 1 with respect to the axis, as shown in Fig. 3.On the other hand, The center G of the support rod body 1601M, which is located on the opposite side of the glare sabaddle 17 from the center of rotation, is located on the opposite side of the sabaddle 17 with respect to the shaft. At the top of the support rod 7, the seat member 1s is attached, and the center of gravity is located at the center of gravity. Axis 1 compared to the factory, which can be manufactured with small materials
located away from the home. Pre, support rod 7, follow, 2
It is found that the total center of gravity G is at a position proportionally distributed according to the weight of the support rod body 1sO weight and the lrena arm isom of the pretsuna paddle couple. Weight material 1
9) Due to the fact that the center of gravity G is located away from the axis, and the presence of the weight material 19, the support rod 7
As the weight proportion of the support body 150 that is moved inward increases, the overall center of gravity G is located at a sufficient distance from the axial line on the side opposite to the pretuna/f dollar 17.

Therefore, the rotation of the fryer and the overall center of gravity GK of the support rod 7 act on the fryer spindle 21. As mentioned above, since the overall center of gravity G is located away from the shaft, the centrifugal force acting on the overall center of gravity GK causes the Pretuna support rod 7 to move clockwise around the axis lIA, around K, and in the 3rd E. Les! The preform formed at the tip of the ret arm 13 is suppressed by the roving formed on the retard arm 13, creating a large pressing force, which allows it to adjust to the increase in the amount of winding. By attaching the weight material 19, the position of the center of gravity G of the Bretsuna 0111 warehouse can be sufficiently separated from the shaft that is the center of rotation without significantly increasing the weight of the Deshitsuna. When the roving machine is started, a sufficiently large turning force is generated for the 7-layer pre-spinning machine, and combined with the fact that the pre-spinning machine is lightweight, the pre-J4 dollar is very fast when the ff1K empty comes into contact with the roving. This makes it possible to automatically wrap the belt. Furthermore, since the weight of the flyer press is only slightly increased, it is well suited for high-speed winding.
In the above-described embodiment, by attaching the weight member 19 to the upper part of the pretuna support rod 7 as much as possible, it is possible to lighten the lower part of the hollow redder and increase the strength of the flyer. A modification of the embodiment described above is shown in FIG. 6 and FIG. 1s7.

In this embodiment, a hollow thread stainless steel 2B is cast into the hollow leg 3 to facilitate the fabrication of the thread guide hole in the hollow redder 3. The fryer body l is
Manufactured from special light alloys such as special aluminum alloys, or materials with relatively low specific gravity such as ceramic steel, etc.
- The lower end of the redder 30 is coaxially attached to the hollow redder 3, and a support rod 7 is rotatably attached thereto. 27 % 7", connect the support rod 7, and connect 29,
The concave portion 29at of the groove 29 is engaged with the convex portion of the hollow redder 3, thereby preventing wobbling and falling off of the cage support rod 7. A rod-shaped member 19 is fixed with adhesive or screwed into a vertical long hole formed in the lower part of the support rod 7. Weight member 1
9 is made of a material such as iron, steel, lead, etc. that has a large specific gravity. In the same way as in the previous embodiment, the overall center of gravity of the plate is located sufficiently far away from the center of rotation on the opposite side of the plate 1/4 dollar 17.

In the embodiment shown in FIGS. 6 and 7, the hollow redder 3
Since the small-volume pre-support rod 7t is attached to the tip of the pre-support rod, the pre-su is lightweight, but by attaching the weight member 19, the overall center of gravity can be moved far enough away from the center of rotation. Since it is located at the same position, it is lightweight, 1 kgf, can generate a large pressing force, and can increase the amount of roving wound.

In addition, in this embodiment, the rotational light diameter of the pre-seat is relatively large and the frictional resistance is somewhat large, but as mentioned above, it is positioned sufficiently far from the center of rotation above the overall center of gravity position, so that the rotation diameter after pipe change is Automatic winding of roving yarn can be performed smoothly. In other words, in FIG. 7, when the bottle is full, the pre-s/mother #1γ is stopped when the full bottle comes into contact with the outer station of the bottle F. Rover's? The full tube moves downward along the bin rail (not shown) and doffs. 't, the roving end is 30
I cut it leaving a length of ~50-, but pre-s/? dollar 1
The empty bottle E is inserted into the flyer bin 21 of the flyer 1 without moving in the diametrical direction of the flyer 7. At this time, a large gap is formed between the empty bottle E and the pre-, sir-, and e-dol. The thread immediately contacts the bottle E, and the end of the roving is wrapped around a special thread wrapping seal (not shown) formed on the bottle IK.

According to the present invention, since it is possible to keep the weight of the spindle light, high-speed winding can be performed, and the overall center of gravity can be positioned sufficiently away from the center of rotation, so that the weight of the spinner can be kept low, and the winding can be carried out at high speed without increasing the weight of the spinner. It is possible to increase the pressing force and increase the amount of roving wound. The lightweight pre-sleeve and overall center of gravity located far from the center of rotation make it easy to automatically wind the roving for the tube replacement bud. In addition, the present invention has a simple structure, is easy to manufacture, and is inexpensive to manufacture.
