Abstract

PURPOSE:To titled supporter where raised parts are formed in an equal interval on the inner surface of the cylindrical major body having a collar on one end and grooves are formed between the raised parts, thus it can be fitted very easily to increase the operation efficiency remarkably. CONSTITUTION:A plurality (3-6) of raised parts having their contact surfaces 7 in the longitudinal direction are formed in an equal interval on the inner peripheral surface of the cylindrical major body 4 which has a collar 6 with a partially cut face 5 on one end and further, grooves 9 of prescribed depth are formed between the raised parts. Thus, it can be easily mounted without inhibiting the lifting pillar from its vertical motion, further the motion of the lifting pillar is not affected, even when flyings and dust sticking to the pillar come into the supporter, resulting in good handleability. The width ratio of the contact surface of the raised parts and the uncontact surface of the grooves is preferably 1:(1-4).

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a support for a lifting machine that is installed in the frame of a spinning machine such as a ring spinning machine or a ring twisting machine, and that supports a ring rail and moves the rail up and down. .

Conventionally, the lifting biller of a spinning machine is fixed and supported by a long cylindrical screw having an upper bearing part 1 and an upper bearing part 2 as shown in Fig. 1, or a push ring is inserted into the sliding surface and supported by a screw. It was firmly fixed and supported.

However, the fluff peculiar to spinning mills adheres to the surface of the lifting biller, and if even a slight abrasion edge is formed on the sliding surface, it gets stuck, making it difficult to move the lifting biller up and down, and requiring maintenance management. It was necessary. For this reason, dust prevention devices have been proposed that prevent fly fluff and dirt attached to the lifting biller from entering the sliding surface, but with conventional dust prevention devices, it is unavoidable that some fly fluff and other particles will enter. As a result, the lifting motion of the lifting biller is obstructed.

Therefore, the lifting biller support device with the dust-proof device has the disadvantage that it requires a lot of effort for its maintenance and management, such as the need to disassemble and clean it. Since it is fixed with screws, not only does it take a lot of effort to install it, but tightening the screws also causes distortion in the support, which is one of the factors that impedes the smooth vertical movement of the sliding biller. There were drawbacks such as.

The present invention solves the above-mentioned conventional drawbacks, and can be easily installed without interfering with the lifting movement of the lifting biller.Also, even if fluff, dirt, etc. attached to the lifting pillar enters the support, the lifting biller cannot be moved up or down. To provide a support for a border pillar that does not impair movement and is easy to handle.

An embodiment of the lifting biller support for a spinning machine according to the present invention will be described below with reference to the drawings.

As shown in FIG.
A plurality (3 to 6) of convex portions each having a contact surface 7 in the longitudinal direction of the main body are provided at equal intervals on the inner circumferential direction of the main body 4, and the contact surface supports the support 7. Furthermore, one or more annular mounting grooves 8 are provided at the lower part of the outer periphery of the main body so that a retaining ring or the like can be mounted. Further, between the convex portions having the contact surface 7 on the inner surface of the main body, a groove 9tl having a required depth (for example, 0.5 M or more) is bored, and the width A of the contact surface 7 of the convex portion and the groove are non-contact. The ratio of B in the surface is preferably A:B-1:1 to 1 to 4 (optimal range 1:2
~3). If the above ratio is small, there is little effect on shedding of fluff, dirt, etc., and if the above ratio is large, the function of the support as a bearing decreases and wear increases.

It is preferable that each contact surface be the same, but the opposing contact surfaces may be the same, and the contact surfaces may be changed depending on the direction in which the force acts.

Further, the length of the main body with respect to the inner radius between the contact surfaces of the main body, that is, the contact surface length L is preferably Dim, -1=1 to 3 (optimal range concavity 1: 1.5 to 2.5).

If the above ratio is small, the function of the support as a bearing will decrease,
If the ratio is large, the effect of shedding of fluff, dirt, etc. will be reduced.

The material for the support for the lifting biller mentioned above is preferably engineering plastics such as polyamide resin, polyacetal resin, polyethylene resin, fluororesin, polycarbonate resin, etc., which have good abrasion characteristics, have low moisture absorption, and are resistant to deformation after processing and installation. It is preferable to use a material with a small value and good W4 slipping properties (for example, an oleoresin).

FIGS. 6 and 4 show the mounting state of the support for the glue 7 and the frame 10 of the present invention on the spinning machine frame 10. The support 3 is inserted into the holes of the main body 4 and the frame 10 with the collar 6 facing upward;
After positioning the notch 5 in a direction perpendicular to the longitudinal direction of the frame so as not to hit the spindle attachment parts, the body 4 is fixed by attaching a retaining ring 11 or the like to the attachment groove 8 of the main body 4'.

Next, another embodiment of the installation state diagram of the beam border biller support device to the upper frame and the lower frame is shown in FIG. ) 15Vc, 1: is installed.

By the way, as shown in FIG. 3, the contact surfaces 7 of the lifting biller support are optimally located at four locations in the longitudinal direction of the frame and in the perpendicular direction thereof, since this reduces deflection caused by the vertical movement of the lifting biller. .

Since the support for the sewing pillar of the present invention has the above-mentioned structure and is attached to the frame of the spinning machine, it is additionally supported on the finishing pillar 12 when fluff, dust, etc. are generated during the operation of the spinning machine, twisting machine, etc. It enters the body and is pushed out into the groove 9 as the fin 7 moves up and down. The fluff, garbage, etc. that have been pushed out and accumulated in the l# gradually travel through the solution and naturally drop downward due to their own weight and the vertical movement of the lifting biller.

Therefore, since the support for a wall edge biller of the present invention has the above-mentioned structure, it can be easily installed by simply inserting the support into the hole in the frame without using screws.
Distortion caused by installation can be eliminated, and there is no obstruction to the lifting motion of the lifting biller as in the past. The ring rail moves up and down smoothly, reducing thread breakage, stabilizing bobbin formation, and reducing power consumption. In addition, it can be used completely without oil, and there is no need for periodic maintenance such as disassembly and cleaning of the 7-inch biller support device as in the past, significantly reducing the number of management steps. Furthermore, it is extremely easy to install, and this invention has the effect of significantly improving operating efficiency.
