The present invention relates to a guide for guiding the lifting and lowering of the heald frame for the opening of the slope during weaving of the fabric using a loom, in particular, to facilitate the lubrication of lubricating oil on the lifting guide, It relates to a heald for lifting looms for looms that allows lubrication effects to last for a long time.

In general, the opening of the slope using the loom (flat weaving machine, dobby loom) is made by the lifting motion of the heald. At this time, as a means for smooth ascent lifting, that is, quiet ascent without shaking, as shown in FIG. 10, the guide port 2 fixedly installed at both sides of the heald frame inside the frame of the loom ( It is guided to the guide groove of 2 ') and lifted.

The guide is provided with a main body made of synthetic resin and the like, and has a plurality of guide grooves on the front of the main body, and the vertical stay of the heald is inserted into each guide groove to guide the lift. At this time, in order to smoothly lift and lower the heald, the guide grooves are lubricated with grease such as grease.

By the way, such a normal lifting guide has no adsorption piece between the vertical stay of a heald and a guide groove, and since grease is apply | coated manually, there exists a following problem.

That is, since the lifting guides are fixedly installed on both side frames of the loom, and the healds are fitted in the guide grooves of the guides, the guide grooves provided at the upper end of the lifting guides are difficult to oil during operation of the machine. The guide groove provided in the worker's hand is not easy to reach there is a significant difficulty in oiling.

In addition, in the initial stage of lubricating oil on the guide groove of the guide, smooth swelling is achieved while the lubricant remains between the guide grooves, but as the weaving progresses, the lubricating oil is exhausted early and wear occurs. .

In addition, if the frequent lubrication on the guide to solve this problem, because there is no space for lubricating oil stagnation, the flow down to the floor, there is a problem that the indoor atmosphere of the workplace is not clean.

On the other hand, the lifting guide (2) of a more improved form is shown in Figure 11, which is provided with a suction piece (21) that can hold the lubricating oil in the center of the main body (20). The lifting guide 2 is formed with a plurality of guide grooves 202 in a direction perpendicular to the ground so that the vertical stay of the heald can be guided, the guide groove in the central portion of the longitudinal direction of these guide grooves 202 The suction piece 21 is provided in the vertical direction so as to cross the 202.

However, even in the case of the conventional lifting guide (2), since there is no place to store the lubricant separately, it is necessary to lubricate the oil often, and the vertically installed suction piece 21 is a short time by gravity no matter how much lubricant oil As it flows down, it should be refueled frequently.

In addition, the adsorption piece 21 is oiled only on one side of the vertical stay of the heald, to catch the vibration of the heald only from the left and right.

In addition, since the vertical stay moves up and down during operation, there is a limit in that oiling is difficult.

The present invention is to solve the above problems, and an object of the present invention is to provide a lifting guide of a loom frame for looms that can be easily oiled on the guide groove.

Another object of the present invention is to lubricate the lubricating oil once in the guide groove on the outer surface of the vertical stay of the heald frame for a long time to prevent wear of the heald frame, so that the oil is not easily flowed to the floor It is to provide the lifting guide of the loom heald for the loom.

In order to achieve the above object, the present invention,

A heald for lifting a loom with a loom coupled to the side of the main frame of the main body, the suction piece having a plurality of second guide grooves connected to the reservoir and aligned with the first guide groove; to provide.

According to another feature of the invention, the side toward the heald frame of the main body, in the middle of the direction perpendicular to the longitudinal direction of the main body, is opened toward the heald frame along the longitudinal direction of the main body, A concave inlet is formed to be separated, the concave inlet and the reservoir communicate with each other through at least one through hole, and the suction piece may be inserted into the concave.

According to another feature of the invention, the upper portion of the body is formed to cover at least the reservoir, the cover member having at least one oil inlet may be further provided.

According to another feature of the invention, the loom healing frame lifting guide for looms are provided with upper and lower lifting guides to guide the upper and lower portions of at least one side of the heald frame, respectively, the reservoir of the upper lifting guide and the lower The reservoir of the elevating guide may be in communication with each other, so that the lubricant in the reservoir of the upper elevating guide may be introduced into the reservoir of the lower elevating guide.

The upper elevating guide and the lower elevating guide may be integrally formed.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a heald frame lifting guide 1 according to a first preferred embodiment of the present invention, FIG. 2 is an exploded perspective view of the main part thereof, FIG. 3 is a sectional view taken along line II of FIG. Is a cross-sectional view taken along II-II of FIG. 2. 5 is a plan view of the main body.

The heald frame lifting guide 1 according to the first preferred embodiment of the present invention has a main body 10 and a first guide projecting at equal intervals on the front surface of the main body 10, that is, the surface facing the heald frame. The protrusions 101 and the first guide grooves 102 recessed between the first guide protrusions 101 are provided. The number of the first guide protrusions 101 and the first guide grooves 102 corresponds to the number of healds, which is determined according to the type of loom used, and is the cost of using healds a lot. In the case of plain weave that uses a lot of healds, the number is reduced.

The central portion of the first guide protrusions 101 and the first guide grooves 102, ie, the main body 10 except for the first guide protrusions 101 ′ disposed at both ends of the first guide protrusions 101. As shown in FIG. 4, the concave portion 103 is formed along the longitudinal direction of the main body 10 in the middle portion of the direction perpendicular to the longitudinal direction of the cross section). This concave inlet 103 is open toward the heald.

The upper and lower portions of the main body 10 are provided with reservoirs 104 for storing lubricating oil. As can be seen in Figures 3 and 4, the reservoir 104 is formed so that the upper and lower parts are symmetrical with respect to the concave inlet 103, can be used in common in the upper and lower left and right of the heald frame, but is not limited thereto. Not necessarily, it may be provided only on one side of the upper or lower portion of the main body 10. And, as can be seen in Figure 5, it can be provided on both sides along the longitudinal direction of the main body 10, wherein the reservoirs on both sides are connected to each other through the passage (108).

As can be seen in Figures 3 to 5, between the concave portion 103 and the reservoir 104 as described above is separated from each other by the bottom portion 105, the through hole 106 formed in the bottom portion 105 Are in communication with each other. However, the present invention is not necessarily limited thereto, and although not illustrated, the gap between the recess 103 and the reservoir 104 may be open to each other without a bottom.

The suction part 103 is fitted with a suction piece 11 as shown in FIG. At this time, the adsorption piece 11 is laid horizontally so that the adsorption piece 11 is adsorbed as much as possible. The suction piece 11 is formed with the second guide protrusions 111 and the second guide grooves 112 on the side facing the front surface, which are the first guide protrusions 101 of the main body 10, respectively. And side by side with the first guide grooves 102.

At this time, as can be seen in Figure 5, the width and depth of each of the second guide grooves 112 formed in the suction piece 11 and the width of each of the first guide grooves 102 of the body 10 and It is formed smaller than the depth, and the width and length of each of the second guide protrusions 111 of the suction piece 11 is formed larger than the width and length of each of the first guide protrusions 101 of the main body 10. This is because when the vertical stay of the heald is guided to the first guide groove 102, the suction piece 11 is directly in contact with the vertical stay, rather than the main body 10, so that the lubricant is well lubricated. This is to be prevented.

A fastening hole 107 is drilled through the center portion and both sides of the main body 10 so as to penetrate the main body 10, and the suction piece 11 is formed with a cut portion 113 at a corresponding position.

On the other hand, the reservoir 104 of the main body 10 is formed with a hose hole 109 in communication with the outside, the hose hole 109, as will be described later, from the upper lifting guide to the lower lifting guide A hose 13 for supplying oil is inserted. At this time, the installation of the hose hole 109 is as shown in Figure 3, the upper volume and the lower volume of the reservoir 104 about the lower end of the inner diameter of the hose 13 inserted into the hose hole 109 is approximately equal. It can be done. That is, in FIG. 3, the volume of the portion A and the volume of the portion B are approximately equal. This is to distribute the lubricating oil to both sides smoothly when the lifting guide is installed on the upper side and the lower side, as will be described later.

The main body 10 as described above may be injection molded by a synthetic resin material, and the adsorbent piece 11 may be a nonwoven fabric such as wool, but any other material may be used as long as the lubricant may soak. .

A cover member 12 provided to cover at least the reservoir 104 is coupled to the upper surface of the main body 10. The cover member 12 is capable of preventing contamination of the reservoir 104 and functioning as a flat washer. A hole 121 is formed to correspond to the fastening hole 107 of the main body 10. In the state in which the hole 121 and the fastening hole 107 are aligned, it may be fastened to the main body 10 by a bolt member or the like. In addition to the cover member 12, an oil injection hole 122 may be formed to inject lubricant into the reservoir 104.

On the other hand, between the cover member 12 and the main body 10 may be formed in the air discharge hole 100 with an inclined gradient toward the outside. According to a preferred embodiment of the present invention, the air discharge hole 100 is formed in the upper end of the main body 10, as shown in Figures 1 and 2, and has an inclined gradient so that its cross-sectional area toward the outside Can be. As described later, the air discharge hole 100 causes the lubricant to be guided from the reservoir to the lower lift guide through the hose when the lubricant is poured into the upper lift guide. In addition, the inclined gradient of the air discharge hole 100 is to be able to smoothly escape even when the lubricant of the reservoir 104 is drawn to the vicinity of the air discharge hole (100).

As shown in FIG. 6, the heald frame lifting guide 1 of the present invention configured as described above is fixed up and down by brackets 42 inside both frames 3 of the loom, and heald frame 4. Guiding the side portion 41).

At this time, the elevating guide (1) located on the upper side and the elevating guide (1 ') located on the lower side are connected to each other by a hose 13, as shown in FIG. That is, one end of the hose 13 is connected to the hose hole 109 of the lifting guide 1 located on the upper side, and the other end is connected to the oil injection hole 122 'of the lifting guide 1' located on the lower side. When the lubricating oil is filled into the reservoir 104 through the oil injection hole 122 located above, the upper lubricating oil of the hose hole 109 or more is automatically distributed by gravity to provide the hose hole 109 and the hose 13. Through the oil injection hole 122 'of the elevating guide (1') located below the bracket 42 is filled in the lower reservoir 104 '. At the same time, lubricating oil is supplied to the suction piece 11 ′ fitted to the main body 10 ′.

At this time, in the case of the lifting guide 1 'located at the lower side, as described above, between the cover member 12 and the main body 10', an air discharge hole 100 'having an inclined gradient toward the outside is formed. ) Is formed so that when oil is lubricated to the upper elevating guide (1), the lubricant flows from the reservoir (104) to the reservoir (104 ') of the lower elevating guide (1') through the hose (13). To be derived. The air discharge hole 100 'has an inclined gradient such that its cross-sectional area is enlarged toward the outside to prevent the lubricant oil in the reservoir 104' from being contaminated from the outside, and even when the lubricant is supplied to the lower reservoir ( 100 ') is the air is drained, so smoothly oiling.

When the loom is operated in the above state, the vertical stay 41 formed on both sides of the heald frame 4 is elevated and guided along the first guide grooves of the elevating guides 1 and 1 '. The lubricating oil adsorbed to the suction pieces 11 and 11 'fitted in the main body is applied to the vertical stay 41 of the mold 4.

That is, in the state where the suction piece 11, 11 'is fitted in the main body 10, 10' of the lifting guide 1, 1 ', the size of the second guide groove is the size of the first guide groove. Smaller, when the side portion 41 of the heald frame 4 is fitted into the first guide groove and the second guide groove, and then elevated, the adsorption pieces 11, 11 'naturally come into contact to surround the side 41, Lubricating oil is always applied to the outer surface of the side portion 41 to enable a smooth lifting operation. In addition, since the adsorption pieces 11 and 11 'surround three surfaces of the side portions 41 of the heald frame 4, the adsorption pieces 11 and 11' simultaneously hold the front, rear, left and right vibrations of the heald frame as a whole.

The lifting guide (1) (1 ') of the present invention greatly lubricates the lifting guide (1) (1') even when the loom is operating in a state where it is fixed on both frames (3) of the loom. Not only can this be facilitated, but the lubricated oil lasted for a long time and there is no dripping to the floor.

That is, the lifting guide (1) (1 ') of the present invention, when lubricating, lubricating oil to the oil injection hole 122 of the cover member 12 coupled to the main body 10 of the upper lifting guide (1) In this case, the lubricated oil is adsorbed to the adsorption piece 11 and supplied to the vertical stay 41 of the heald, and the lubricating oil above the inlet of the hose hole 109 of the upper elevating guide 1 main body 10 is a hose ( Since it is supplied to the suction piece 11 'of the elevating guide 1' located at the lower side through 13), it is not necessary to oil directly to the lower elevating guide as before.

In addition, the lubricated oil is adsorbed by the adsorption pieces 11, 11 'fitted to the lifting guides 1, 1', so that the lubricant does not flow down during the operation of the loom, Since it is maintained for a long time, wear due to lack of lubrication can be prevented.

Particularly, in the present invention, in the case of the heald which frequently operates among the healds that come into contact with the adsorption pieces 11 and 11 ', the oil consumption is high and the density of the lubricant is lowered. Will supply a lot of lubricant towards the heald. In the case of a heald with little or no momentum, the consumption of lubricant is relatively low, and the density of the lubricant is high. Therefore, the supply of lubricant is reduced toward the heald. Therefore, the lubricating oil supply is made automatically from the higher density to the lower density, so that only a suitable amount of lubricating oil is consumed as a whole and it is economical.

The lifting guide as described above can be modified into various shapes. 8 is an exploded perspective view showing the main body 10 of the lifting guide according to the second embodiment of the present invention, which is formed by injection molding. It can be formed to be almost symmetrical up and down during injection molding.

In addition, by reducing the depth of the concave inlet portion 103, the reservoir can be made larger, the lubricating oil supply period can be lengthened, and the lubricating oil supply frequency can be reduced.

9A and 9B are cross-sectional and side views showing the elevating guide according to the third embodiment of the present invention, respectively, wherein the upper elevating guide 1 and the lower elevating guide 1 'shown in FIG. It is formed integrally. Since the detailed configuration is the same as described above, a description thereof will be omitted. However, in the case of the reservoir 104 ′ located at the lower side, as a matter of processing, as shown in FIG. 9B, the reservoir member 123 is disposed at both sides with a stopper member 123. 104 ').

According to the present invention made as described above can obtain the following effects.

First, lubricating oil can be easily and quickly achieved even during operation of the loom.

Second, since the lubricated oil is maintained for a long time, and the efficiency is high, the consumption of lubricating oil is low, so that it does not flow into the workplace, it is possible to keep the workplace clean. In addition, environmental pollution prevention effect can be obtained.

Third, it is possible to suppress the vibration as much as possible by guiding the three sides of the heald frame.

Fourth, since the lubricating oil is continuously supplied to the guided portion of the heald, the wear caused by the lifting of the heald can be minimized.

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art will be variously modified and changed within the scope of the invention without departing from the spirit and scope of the invention described in the claims below I can understand that you can.
