Description

[Detailed description of the invention] The present invention relates to a bearing support device for a lifting pillar that is installed on a spindle rail of a ring spinning machine, a ring twisting machine, etc., and that supports the ring rail and moves the rail up and down. The structure is designed to reduce friction between parts and to facilitate dust-proofing and maintenance.

Fig. 1 is a partial front schematic view showing an example of a spinning spinning machine, in which spindle bolsters 4 are arranged at regular intervals on a spindle rail 3 fixed to a frame (not shown), and a spindle 7 is rotated on this. It can be inserted freely.

The spindle 7 is rotated at high speed by a driving tape (not shown) that is stretched around the spindle warb 7a.

On the other hand, a ring 6 is disposed surrounding the spin lure, and each ring 6 is connected to a ring rail 5.
is supported by

The thread is then wound around a bobbin inserted into the spindle 7 via a traveler loosely fitted to the ring 6, and the shape of the winding is determined by the raising and lowering of the ring rail 5.

Both ends of the ring rail 5 are supported by brackets 2a provided at appropriate intervals or attached to the top of the bordering pillar 2, and the lifting pillar 2 moves up and down as shown by arrow A to form a bobbin.

In this manner, the collar bushing 1 is used to accurately guide the border pillar 2 along the spindle 7 and to smoothly move it up and down. They are arranged so as to penetrate through the lower flange portions 3b, respectively.

By the way, the friction between the collar bushing 1 and the lifting biller 2 has a direct effect on the thread forming, so it must be extremely smooth, and the bushing 1 and the pillar 2 must be separated in order to keep the center of the ring 6 aligned with the spindle 7. It is required that there be no

FIG. 2 is a cross-sectional view of an old bushing. The upper side 1a and the lower side 1b of the bushing 1 are formed as sliding surfaces by fitting the bushing body or another bushing ring, and the bushing 1 is formed as a sliding surface by fitting the bushing body or another bushing ring. was decreasing.

Therefore, the fluff peculiar to the spinning factory adheres to the surface of Pillar 2,
If a slight wear gap is formed on the sliding surface, it will dig into the gap, clogging the bush 1 and the pillar 2, making it difficult to move the pillar 2 up and down, and requiring a lot of effort for maintenance.

Among these, bushing materials made of synthetic resin that do not require oiling have been used, and in order to eliminate clogging due to fluff, etc., products have been developed in which part of the sliding surface is formed with a communicating groove. As shown in the figure (interrupted cross-sectional view), a bushing 1 with fitting grooves 8 formed in the upper and lower parts (not shown) and fitted with rings 9 molded from wear-resistant synthetic resin is used. .

Further, the ring 9 is connected to the sliding surface of the pillar 2 and the gap 9 as shown in FIG.
When attaching and detaching, a notch 9C is formed in a part around the ring 9, and the ring 9 is fitted with a reduced diameter and held in the fitting groove 8 by elastic force. It was something to do.

Although the bushing 1 configured in this way can achieve considerable effects and is currently in widespread use, it is time-consuming to replace the ring 9 and clean the inside of the bushing 1, and maintenance is required. It has been desired to develop an easy support device.

The present invention was developed as a result of various studies focusing on these points, and is an attempt to provide a border pillar support device that satisfies the above-mentioned needs.

However, this invention involves attaching a pillar bearing member consisting of a ring or contact piece made of a wear-resistant material in a short cylinder to the upper and lower sides of the spindle rail, and attaching the pillar bearing member to the upper and lower sides of the spindle rail. The opposing side edges of both short tubes are made to protrude from the mounting portion of the spindle rail, respectively, and a split type dustproof cover is placed over both of the protruding portions.

The present invention will be explained in detail below based on the drawings. However, the drawings show an example of a specific implementation of the present invention, and the present invention is not limited to these illustrated examples, but can be constructed in accordance with the spirit of the above and below. The same implementation is possible even if the shapes of the parts or part of the configuration is changed.

Figure 6 is a partially cutaway sketch of the support device to which the present invention is applied;
Figures 7 and 8 are diagrams explaining the structure of the short-tube bushing, Figure 9
10 and 10 are exploded sketches of FIG. 6, and FIGS. 11 and 12 are enlarged sectional views of the dustproof cover.

In these figures, the present invention eliminates the conventionally used collar bushing 1, and replaces it with split-type dustproof covers that are easy to attach and remove.Moreover, the dustproof covers are attached to the upper and lower parts of the spindle rail, respectively. It is configured to be held by a provided pillar support member.

That is, as shown in FIG. 6, the upper flange 3a and lower flange 3b of the spindle rail 3 are attached
Short cylindrical bushings 10.10 are attached to the arrangement portion, and each is fixed with stoppers 10a and 10b.

On the other hand, as shown in FIG. 7, the short tube push 10 has three to four rows (four rows in the figure) of cut grooves 11a formed at equal intervals on the circumferential wall of the metal short tube 11. It is configured by fitting the piece 12c.

It is recommended that the wear-resistant piece 12c be made of a synthetic resin material with excellent wear resistance, but it may also be made of a wear-resistant metal material, and during molding, a groove is formed on the back side to be inserted into the cut groove 11a as shown in the figure. It is recommended that the ventral side be a flat surface that makes line contact with the outer peripheral surface of the lifting pillar 2.

It is also desirable to use an adhesive when inserting the wear-resistant piece 12c.

Further, the length of the short tube 11 in the height direction is formed to be longer than the thickness of the spindle rail flange portion.

FIG. 8 shows another configuration example of the short cylindrical bushing 10, in which the wear-resistant piece in the example in FIG. 7 is formed as a synthetic resin ring. Form.

Although the contact surface 12a is shown as a sliding concave surface (along the outer peripheral surface of the pillar), it may be flat as shown in FIG.
Alternatively, the third row may be formed at equal intervals.

In addition, when molding the resin ring 12, only the ring 12 may be molded and fitted into the short tube 11, but it is recommended that insert molding is performed within the short tube 11. to engage the resin layer.

It is convenient to handle this short-tube bushing 10 as a replacement consumable item.

On the other hand, when installing the short tube push 10, as shown in a part of FIG. 6 and FIG. (machining the conventional color bushing mounting hole to a larger diameter),
One end of the short tube 11 is made to protrude inside the spindle rail 3, and is fixed with screws 10a and 10b.

If the pillar 2 is simply inserted through the short cylindrical bushing provided in this way, the fluff will adhere to the circumferential surface of the pillar 2, and although sliding with the bushing is almost smooth due to the synthetic resin material and the groove formation, the pillar It is now more necessary than ever to clean up the fluff adhering to 2.

Accordingly, the present invention includes the provision of a dustproof cover 13 between the short cylindrical bushings 10 and 10, and the installation thereof using the inner protrusion of the short cylindrical bushings.

That is, the dust-proof cover 13 may be simply a two-piece cylinder along the protrusion, but as shown in FIG. 10, half pieces 13a, 13b are used, and a hinge 14, 14 is recommended.

The inner diameter of the cover 13 when closed is formed to approximately match the outer diameter of the short tube 11, and when closed, the half piece 1
It is recommended that the mating edges of 3a, 13b be provided with means for engaging each other.

As such an engaging means, any suitable device known in the art can be used, but for example, as shown in FIG.
The engagement protrusion 13c is formed on the side 3a, and the protrusion 1 is formed on the side 13b.
It is preferable to attach elastic engagement plates 15 that engage with the hinges 3c, and such engagement portions may be provided at two or three locations in the same way as the hinges 14.

FIG. 12 shows another engagement means, in which a retaining pin support member 16 is fixed on the half piece 13a side, and a hook-shaped hook 17 on the 13b side that can be swung by a knob 17a projecting outward.
It is composed of

In such a securing device, the knob 17a facilitates handling of the cover, and it is sufficient to provide the knob 17a at one location.

Since the footing pillar support device of the present invention is constructed in this manner, the pillars can be smoothly moved up and down, and the pillars can be cleaned easily, and the bushings can be replaced individually.

Furthermore, since the dustproof cover has an extremely simple installation structure, maintenance management is easy.
