Description

  The present invention relates to a guide that guides the lifting and lowering of a hook frame for opening a warp yarn when weaving a fabric using a loom, and in particular, facilitates the lubrication of lubricating oil onto the lifting guide and at the same time. The present invention relates to a lifting guide for a weaving frame for a loom that can maintain a lubricating effect for a long time by lubrication.

  Generally, the opening of the warp yarn using a loom (a plain loom, a dobby loom) is made by a lifting and lowering movement of the heel frame. At this time, as means for smoothly raising and lowering the kite, i.e., smooth raising and lowering without shaking, as shown in FIG. 10, the guide tools 2, 2 in which both side portions 41 of the kite frame are fixed to the inside of the loom frame. Go up and down guided by 'guide groove'.

  The guide has a main body made of a synthetic resin or the like, and has a plurality of guide grooves on the front surface of the main body, and a vertical stay of a collar frame is sandwiched in each guide groove and is guided up and down. At this time, lubricating oil such as grease is poured into the guide groove for smooth raising and lowering movement of the eaves frame.

  However, such a normal elevating guide has the following problems because there is no adsorbing piece between the vertical stay of the saddle frame and the guide groove and grease is applied manually.

  In other words, since the lifting guides are fixed inside the frames on both sides of the loom, and the eaves frame is sandwiched between the guide grooves of the guides, the guide grooves provided at the upper end of the lifting guides are machined. It is difficult to lubricate during operation, and in particular, the guide groove provided at the lower end is not easily reachable by the operator and has a considerable difficulty in lubrication.

  In addition, in the initial stage when lubricating oil is poured into the guide groove of the guide tool, the lubricating oil remains smoothly between the guide grooves, and the smooth rising and lowering is performed, but as the weaving progresses, the lubricating oil immediately disappears at the friction part. Phenomenon occurs.

  In addition, if frequent lubrication is performed on the guide tool in order to solve this problem, there is no space where the lubricating oil stays, so there is a problem that the indoor atmosphere of the workplace becomes dirty.

  On the other hand, the lifting guide 3 having a more improved form is shown in FIG. 11, and this includes a suction piece 31 that can hold lubricating oil at the center of the main body 30. In such an elevating guide 3, a plurality of guide grooves 302 are formed in a direction perpendicular to the ground so that the vertical stay of the eaves frame can be guided, and at the center in the longitudinal direction of these guide grooves 302, The suction piece 31 is provided in the vertical direction so as to cross the guide groove 302.

  However, even in the case of such a conventional lifting guide 3, there is no place for separately storing the lubricating oil, so the lubricating oil must be frequently injected, and the vertically installed suction pieces 31 are lubricated. Even if you add more oil, it will flow in a short time due to gravity, so you have to add oil frequently.

  Further, the suction piece 31 is oiled only on one side of the vertical stay of the frame, and the vibration of the frame is prevented only on the left and right.

  And since the vertical stay is moving up and down during operation, there is a limit that is difficult to lubricate.

  The present invention is intended to solve the above-described problems, and has an object to provide a lifting guide for a loom frame for a loom that can easily lubricate guide grooves.

  Another object of the present invention is to prevent the wear phenomenon of the collar frame by lubricating the lubricant once lubricated into the guide groove so as to be applied and lubricated on the outer surface of the vertical stay of the collar frame for a long time. It is another object of the present invention to provide a lifting guide for the loom frame for preventing the lubricating oil from flowing to the bottom easily.

  In order to achieve the above-described object, the present invention provides a main body formed long in the direction in which the loom frame of the loom is arranged, and the main frame is formed along the longitudinal direction of the main body. A plurality of first guide grooves provided so as to be guided, at least one tank provided in at least an upper part of the main body for storing lubricating oil, and coupled to an opposite side of the main frame of the main body And a lifting guide for the loom frame for a loom comprising a suction piece having a plurality of second guide grooves that are communicated with the tank and aligned with the first guide grooves.

  According to another feature of the present invention, on the opposite side of the main frame of the main body, an intermediate portion in a direction perpendicular to the longitudinal direction of the main body, toward the vertical frame along the longitudinal direction of the main body. A notch formed to be opened and separated from the tank is further provided, the notch and the tank communicate with each other through at least one through hole, and the suction piece may be inserted into the notch. .

  According to still another aspect of the present invention, a cover member may be further provided at an upper portion of the main body so as to cover at least the tank and having at least one oil inlet.

  According to still another aspect of the present invention, the lifting guide for the loom frame is provided with an upper and lower lifting guide so as to guide an upper part and a lower part on at least one side of the fence frame, The tank of the upper lift guide can be communicated with the tank of the lower lift guide so that the lubricating oil in the tank of the upper lift guide can flow into the tank of the lower lift guide.

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

  According to the present invention, the following effects can be obtained.

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

  Secondly, since the lubricated oil is retained for a long time, the efficiency is high, and the amount of lubricant consumption is small, it is prevented from flowing to the bottom of the work place, and the work place can be kept clean. Not only that, it can also prevent environmental pollution.

  Third, vibration can be prevented as much as possible by guiding it so as to wrap the three sides of the collar frame.

  Fourthly, since the lubricating oil is continuously supplied to the guide portion of the collar frame, wear due to the raising and lowering of the collar frame can be reduced to the minimum.

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

  FIG. 1 is a perspective view of a lifting / lowering guide 1 for a saddle frame according to a first preferred embodiment of the present invention, FIG. 2 is an exploded perspective view of an essential part thereof, and FIG. 4 is a cross-sectional view taken along line II-II in FIG. 2. FIG. 5 is a plan view of the main body.

  The elevating and lowering guide 1 for the eaves frame according to the first preferred embodiment of the present invention includes a main body 10, first guide protrusions 101 protruding at equal intervals on the front surface of the main body 10, that is, the opposing surface of the eaves frame, And a first guide groove 102 that is recessed between the first guide protrusions 101. The number of the first guide protrusions 101 and the first guide grooves 102 corresponds to the number of hook frames, but it is determined by the type of loom used, and in the case of a dobby loom using many hook frames, the number is increased. However, in the case of a plain weaving machine that uses a small number of hook frames, the number is reduced.

  Of the first guide protrusion 101, the central portion of the remaining first guide protrusion 101 and the first guide groove 102 excluding the first guide protrusion 101 ′ positioned at both ends, that is, perpendicular to the longitudinal direction of the main body 10 As shown in FIG. 4, a cut portion 103 is formed along the longitudinal direction of the main body 10 at an intermediate portion in one direction. The notch 103 is opened toward the frame.

  A tank 104 for storing lubricating oil is formed at the upper and lower portions of the main body 10. As can be seen from FIGS. 3 and 4, the tank 104 is formed so that the upper part and the lower part are symmetrical with respect to the notch 103, and can be used in common for the upper, lower, left, and right sides of the eaves frame. In some cases, the main body 10 may be provided only on one side of the upper part or the lower part. As shown in FIG. 5, it may be provided on both sides along the longitudinal direction of the main body 10. At this time, the tanks on both sides are connected to each other through a passage 108.

  As shown in FIGS. 3 to 5, the notch 103 and the tank 104 are separated from each other by a bottom 105 and communicated with each other through a through hole 106 formed in the bottom 105. However, the present invention is not necessarily limited thereto, and the notch 103 and the tank 104 may be open to each other without a bottom even if not shown in the drawing.

  A suction piece 11 as shown in FIG. 2 is sandwiched and installed in the notch 103. At this time, the adsorbing piece 11 is sandwiched horizontally so that the maximum amount of lubricating oil is adsorbed thereto. The suction piece 11 is formed with a second guide protrusion 111 and a second guide groove 112 on the opposite side of the front surface thereof, which are aligned with the first guide protrusion 101 and the first guide groove 102 of the main body 10, respectively. Aligned.

  At this time, as illustrated in FIG. 5, the width and depth of each of the second guide grooves 112 formed in the suction piece 11 are smaller than the width and depth of each of the first guide grooves 102 of the main body 10. The width and length of each of the second guide protrusions 111 of the suction piece 11 are 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 eaves frame is guided to the first guide groove 102, the suction piece 11 is in direct contact with the vertical stay rather than the main body 10 and lubrication is improved, and vibration is prevented during the vertical movement of the eaves frame. Because.

  A fastening hole 107 is formed in the central portion and both side portions of the main body 10 so as to penetrate the main body 10, and a cutting portion 113 is formed in the suction piece 11 at a corresponding position.

  On the other hand, the tank 104 of the main body 10 is formed with a hose hole 109 communicating with the outside, and oil is supplied to the lower lifting guide from the upper lifting guide as will be described later. A hose 13 is inserted. At this time, as shown in FIG. 3, the hose hole 109 is installed such that the upper volume and the lower volume of the tank 104 are substantially the same with the lower end of the inner diameter of the hose 13 inserted into the hose hole 109 as the center. be able to. That is, in FIG. 3, the volume of the A portion and the volume of the B portion are made substantially the same. As will be described later, this is to facilitate the distribution of the lubricating oil to both when the lifting guide is installed on the upper side and the lower side.

  The main body 10 may be injection-molded with a synthetic resin material, and the adsorbing piece 11 may be a non-woven fabric such as wool, but any other material that can be infiltrated with lubricating oil or the like may be used. It may be a thing.

  A cover member 12 provided to cover at least the tank 104 is coupled to the upper surface of the main body 10. The cover member 12 can function as a flat washer by preventing the tank 104 from being contaminated. A hole 121 is formed so as to correspond to the fastening hole 107 of the main body 10. The main body 10 can be fastened to the main body 10 with a bolt member or the like in a state where the main body 107 is aligned. In addition, an oil injection hole 122 is formed in the cover member 12 so that lubricating oil can be injected into the tank 104.

  On the other hand, between the cover member 12 and the main body 10, an air discharge hole 100 having an inclined gradient toward the outside may be formed. According to a preferred embodiment of the present invention, the air discharge hole 100 is formed at the upper end of the body 10 as shown in FIGS. Can have an inclined slope. As will be described later, the air discharge hole 100 guides the lubricating oil from the tank to the lower lifting guide through a hose when lubricating the upper lifting guide. In addition, the slope of the air discharge hole 100 is for smoothly discharging even when the lubricating oil in the tank 104 is scattered in the vicinity of the air discharge hole 100.

  As shown in FIG. 6, the elevating guide 1 for the eaves frame of the present invention configured as described above is vertically fixed by brackets 42 inside the both side frames 3 of the loom, Guide the part 41.

  At this time, the lifting guide 1 located on the upper side and the lifting 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. If the tank 104 is filled with lubricating oil through the oil injection hole 122 located at the upper part, the upper lubricating oil on the hose hole 109 is automatically distributed by gravity and is moved to the lower side of the bracket 42 through the hose hole 109 and the hose 13. The lower tank 104 ′ is filled through the oil injection hole 122 ′ of the lift guide 1 ′ positioned. At the same time, lubricating oil is supplied to the adsorbing piece 11 ′ sandwiched between the main bodies 10 ′.

  At this time, in the case of the lifting guide 1 ′ positioned on the lower side, as described above, the air discharge hole 100 in which an inclined gradient is formed between the cover member 12 and the main body 10 ′. When 'is formed and lubricating oil is poured into the upper lifting guide 1, the lubricating oil is guided from the tank 104 to the tank 104 ′ of the lower lifting guide 1 ′ by gravity through the hose 13. The air discharge hole 100 ′ has an inclination so that its cross-sectional area increases toward the outside, prevents the lubricating oil in the tank 104 ′ from being contaminated from the outside, and supplies the lubricating oil to the lower tank. Even when the air is discharged, the air escapes through the air discharge hole 100 ', so that lubrication is smoothly performed.

  If the loom is operated in the state as described above, the vertical stays 41 formed on both sides of the eaves frame 4 are guided up and down along the first guide grooves of the elevating guides 1 and 1 ′. Lubricating oil adsorbed by the adsorbing pieces 11 and 11 ′ sandwiched in the main body is applied to the vertical stay 41 of the frame 4.

  That is, the suction pieces 11 and 11 ′ are sandwiched in the main bodies 10 and 10 ′ of the lifting guides 1 and 1 ′, and the size of the second guide groove is smaller than the size of the first guide groove. When the four side portions 41 are sandwiched between the first guide groove and the second guide groove and moved up and down, the adsorbing pieces 11 and 11 ′ come into contact with each other so as to wrap around the side portion 41. Lubricating oil is applied to enable smooth elevating operation. Further, since the adsorbing pieces 11 and 11 'wrap around the three surfaces of the side portion 41 of the collar frame 4, the longitudinal and lateral vibrations of the entire collar frame are simultaneously prevented.

  The lift guides 1 and 1 'according to the present invention can be used to inject lubricating oil into the lift guides 1 and 1' even when the loom is operating in a state of being fixed on both frames 3 of the loom. Not only easily, but also the lubricated oil is retained for a long time and does not flow to the bottom.

  In other words, the lifting guides 1, 1 ′ of the present invention, if the lubricating oil is injected into the oil injection hole 122 of the cover member 12 coupled to the main body 10 of the upper lifting guide 1 at the time of lubricating, The lubricating oil supplied to the vertical stay 41 of the eaves frame while being adsorbed by the adsorbing piece 11, and the lubricant on the inlet of the hose hole 109 of the main body 10 of the upper elevating guide 1 is moved up and down through the hose 13. Therefore, it is not necessary to directly lubricate the lower lifting guide once at a time as in the prior art.

  In addition, the lubricated lubricating oil is not only stopped by the suction pieces 11 and 11 ′ sandwiched between the lifting guides 1 and 1 ′ and not flowing down during the operation of the loom, but is lubricated once. Since the lubricating oil is retained for a long time, wear due to insufficient lubrication can be prevented.

  In particular, in the present invention, in the case of a saddle frame that performs frequent operations among a large number of saddle frames that come into contact with the suction pieces 11, 11 ′, the lubricant is consumed much and the density of the lubricant is low, A large amount of lubricating oil is supplied from the tank to the frame side. In the case of a saddle frame with little or no momentum, the consumption of lubricating oil is relatively small and the density of the lubricating oil is high, so that the supply of lubricating oil to the side of the saddle frame is reduced. Accordingly, the lubricating oil is automatically supplied from the high density side to the low density side due to the density difference, so that only an appropriate amount of lubricating oil is consumed as a whole, which is economical.

  The lifting guide as described above can be transformed into various shapes. FIG. 8 is an exploded perspective view illustrating the main body 10 of the lifting guide according to the second embodiment of the present invention, which is formed by injection molding. This can be formed almost symmetrically at the time of injection molding.

  Further, by reducing the depth of the cut portion 103 and further increasing the tank, it is possible to extend the lubrication time and reduce the frequency of supply of the lubricant.

  9A and 9B are a cross-sectional view and a side view, respectively, illustrating a lifting guide according to a third embodiment of the present invention, and an upper lifting guide 1 and a lower lifting guide 1 ′ shown in FIG. Are integrally formed. Since the detailed configuration is as described above, the description is omitted. However, in the case of the tank 104 ′ located on the lower side, due to processing problems, as shown in FIG. 104 'can be sealed.

  Although the foregoing has been described with reference to the preferred embodiments of the present invention, those skilled in the art can variously modify and change the present invention without departing from the spirit and scope of the present invention as defined in the appended claims. Can understand.

  The present invention is suitably used for various textile machines for weaving fabrics.
