JP4462172B2 - Reed frame guide device in warp opening device of loom - Google Patents

Description

  The present invention relates to a reed frame guide device in a warp opening device of a loom that guides the vertical movement of the reed frame by a guide mechanism disposed on the side of the reed frame.

  In the warp opening device, there is a so-called positive opening method in which the reed frame is reciprocated up and down by a reciprocating driving force transmitted from a driving source disposed below the loom. An example of this is shown in FIG.

  A rigid drive rod 3 extending in the vertical direction is disposed on the outer side of the side stay 2 constituting the collar frame 1. The upper end 7 of the drive rod 3 is covered with a pair of bowl-shaped holders 6, 6. The holders 6, 6 and the upper end of the side stay 2 are surrounded by the clamp 4, and are integrated by tightening the bolt 5. .

  Further, a male screw is engraved on the upper end portion 7 of the drive rod 3, and a height adjusting nut 8 and a lock nut 9 are screwed therein to form a height adjusting mechanism for the eaves frame 1. When adjusting the height of the eaves frame 1, the bolt 5 and the lock nut 9 of the clamp 4 are loosened, and the eaves frame 1 can be moved upward or downward by turning the height adjustment nut 8.

  A link 11 is fixed to the lower end of the drive rod 3, and the link 11 is connected to a three-pronged swing lever 13 that can rotate about a shaft 12 by a connecting portion 13 a. The swing lever 13 passes through the through hole 19 of the frame 18 of the loom, is connected to a drive link 14 connected to a drive source (not shown), and is reciprocated.

On the other hand, the swing lever 13 similarly moves up and down a drive rod having the same structure disposed on the left side (left side in FIG. 9) of the frame 1 (not shown) via the connecting link 15.
Accordingly, since the drive rod 3 is reciprocated up and down by the reciprocating motion of the swing lever 13, the heel frame 1 integrated by the clamp 4 is moved up and down together, and a warp opening motion (not shown) is performed.

The heel frame 1 and the drive rod 3 prevent the loom from moving back and forth in the front-rear and left-right directions due to vertical movement, and a pair of upper and lower guide members 56 disposed on the outer side of the side stay 2 so that stable warp opening movement is performed. Guided by a guide groove. Although a similar guide member is not shown, the guide member 56 disposed on the outer side of the left frame 1 on the left side in FIG. 9 is also provided with a support bracket 57 fixed to the shaft 59 attached to the frame 18 by a bolt 58. Is held at the guide position.

  By the way, in a loom, with the change of the textile specification, an operation of replacing the old warp yarn with the new specification together with the reed frame 1 is frequently performed. That is, in the warp opening device having the above-described configuration, the bolt 5 is loosened, the clamp 4 is removed, and the collar frame 1 is lifted upward to be removed from the guide member 56. Next, the operation | work which inserts the new collar frame 1 in the guide groove of the guide member 56 from upper direction is performed.

  However, since the guide groove of the guide member 56 has a very narrow width that is almost equal to the thickness of the collar frame, and at least four or more of the collar frames are used, usually about 8 to 16 sheets, It has been very difficult to accurately insert these flange frames into the guide groove of the guide member 56 from above, requiring complicated work and a great deal of time.

In order to facilitate these frame frame insertion operations, a frame frame guide moving mechanism disclosed in Patent Document 1 has been proposed.
As shown in the specification and drawings of Patent Document 1, the saddle frame guide moving mechanism of Patent Document 1 is slid and fixed in a cylinder 40 in which the support shaft 21 of the saddle frame guide 20 is attached to the loom frame 10. In this structure, the support shaft 21, which is fitted so as to be capable of being released, is moved in parallel in the axial direction by the guide of the cylinder 40, so that the guide frame guide 20 is separated from the guide frame 30.

A warp frame guide moving mechanism disclosed in Patent Document 1 is employed in the warp opening device shown in FIG.
That is, in FIG. 9, the bolt 5 is loosened, the clamp 4 is removed, and the coupling between the side stay 2 and the drive rod 3 is released. Next, the bolt 58 is loosened, and the support bracket 57 together with the drive rod 3 and the guide member 56 is translated along the shaft 59 toward the frame 18 to separate the guide member 56 from the side stay 2.
Japanese Patent Laid-Open No. 10-140436

  However, in the case of the warp opening device shown in FIG. 9, unlike the warp opening device of Patent Document 1, the guide member 56 has a structure that moves together with the drive rod 3. Since the drive rod 3 is coupled to the lower end link 11 and the swing lever 13 by the connecting portion 13a and cannot be moved in parallel, the support bracket 57 must move while the drive rod 3 is bent.

As a result, the guide member 56 can be separated from the side stay 2, but only a slight gap can be formed.
In such a state, when the collar frame 1 is removed, there is no particular problem because it only needs to be lifted upward. However, when the collar frame 1 is attached, it must be inserted into the guide groove of the guide member 56 from above as well. However, there is a problem that it is difficult to insert the gutter frame, and a complicated operation must be performed by a plurality of workers.

SUMMARY OF THE INVENTION An object of the present invention is to provide a warp opening device in which a drive rod reciprocated in the vertical direction by a drive source disposed below a loom and a heel frame are connected to each other.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
The warp opening device to which the present invention is directed has the same configuration as the warp opening device described in FIG. 9, and therefore, the same parts are denoted by the same reference numerals, and the components that have not been described in FIG. 9 are added. I will explain it.

  A plurality of eaves frames 1 are used, and in this embodiment, eight eaves frames are used as shown in FIG. Accordingly, a drive mechanism that reaches the drive rod 3 via the link 14, the swing lever 13, and the link 11 that are connected to the drive source is disposed corresponding to each frame 1. Further, as is apparent from FIG. 1, the drive rod 3 is arranged in the same structure corresponding to the left and right side stays 2 of the collar frame 1, and the left drive rod 3 in FIG. Is connected to a connecting link 15 connected to a swing lever 13 and is connected to an L-shaped swing lever 17 that rotates about a shaft 16 and is moved up and down. Accordingly, during the operation of the loom, the left and right drive rods 3 and 3 move up and down synchronously, so that the collar frame 1 connected to the drive rods 3 and 3 by the clamps 4 and 4 moves up and down, and the warp opening movement Is done.

Since the guide mechanisms 10 and 10 arranged at the guide positions on the outer side of the collar frame 1 have the same configuration on the left and right, the configuration of the guide mechanism 10 shown on the right side of FIG. 1 will be described below.
The guide mechanism 10 includes a guide member 26 that guides the collar frame 1 that is disposed at two locations, and a holding member 30 for the guide member 26.

As shown in FIG. 5, the guide member 26 is made of resin and has at least the same number of comb-shaped guide grooves 27 opened on the side of the collar frame 1 as the collar frame 1 to be used. It fits so that it can move. In addition, a plurality of guide grooves 28 that allow the drive rod 3 disposed corresponding to each side stay 2 to move up and down are formed on the side opposite to the guide grooves 27.
The guide member 26 is fixed to the holding plate 25 by bonding or screwing the guide groove 28 side, and the guide groove 28 is opened only in the vertical direction.

  As shown in FIG. 4, the holding member 30 includes a central cylinder 22 and two arms 20 and 21 extending upward and downward from the cylinder 22. The arm 20 fixes the holding plate 25 of the guide member 26 in the upper position to the tip portion 23 with a bolt 29, and the arm 21 fixes the holding plate 25 of the guide member 26 in the lower position to the tip portion 24 with a bolt 29. Thus, the guide member 26 and the holding member 30 at the upper and lower positions are integrated.

  As shown in FIG. 3, the cylinder 22 has a large-diameter inner wall portion 31 formed on the side of the collar frame 1, and a halved portion 33 having a small-diameter inner wall portion 32 formed on the frame 18 side. The cylinder 22 further includes a half member 36 having an inner wall portion 35 having the same diameter as the inner wall portion 32 of the half portion 33. Further, as shown in FIG. 2, the half member 36 is provided with counterbored portions 37 at two locations in the front-rear direction of the loom on the outer peripheral surface thereof, and can be fixed to the half portion 33 with bolts 38 as fastening members. Therefore, the cylinder 22 is fixed to the fixed shaft 34 by fitting the cylinder 22 to the fixed shaft 34 and then covering the half member 36 on the fixed shaft 34 and screwing the bolt 38 into the half portion 33. Can be arranged at the guide position of the collar frame shown in FIG. At this time, the fixed shaft 34 comes into contact with the inner wall portion 35 of the half member 36 and the inner wall portion 32 of the half portion 33, and a space 31 a is formed between the fixed shaft 34 and the large-diameter inner wall portion 31. .

The operation of the first embodiment configured as described above will be described below.
During normal operation of the loom, the guide mechanism 10 is set to the guide position in FIG. 1, and the side stay 2 is fitted into the guide groove 27 of the guide member 26 and the drive rod is inserted into the guide groove 28 as shown in FIG. 3 is fitted, the cylinder 22 is fitted to the fixed shaft 34 as shown in FIG. 3A, and is fixed by tightening the half member 36 and the bolt 38. Therefore, the guide member 26 can guide the rod frame 1 and the drive rod 3 in a stable state during operation of the loom.

  When a new machine is required due to a change in the weaving specifications, the operator stops the loom and performs the following operations. Prior to the work, all the cage frames 1 are held by suspension means such as a lift or a crane. In this state, the operator first loosens the bolt 5 to release the coupling between the side stay 2 and the drive rod 3. The clamp 4 moves above the upper end of the side stay 2 along the hook-shaped holder 6 of the drive rod 3 and is attached to the upper end position shown in FIG. Next, the bolt 38 of the half member 36 is loosened to release the coupling between the cylinder 22 and the fixed shaft 34.

  When the guide mechanism 10 in the free state is moved to the right in FIG. 1, the drive rod 3 is held in the guide groove 28 of the guide member 26, so that the connection portion 13 a with the swing lever 13 is centered. Tilt. At this time, there is a space 31 a between the fixed wall 34 in the inner wall portion 31 of the cylinder 22, and the coupling between the half member 36 and the half portion 33 is released, and above the half portion 33. However, there is virtually free space. Therefore, a change in the height position between the cylinder 22 and the fixed shaft 34 in accordance with the tilting of the drive rod 3 is allowed, and the cylinder 22 is near the boundary between the large-diameter inner wall portion 31 and the small-diameter inner wall portion 32. It is possible to tilt around the center. Accordingly, as shown in FIG. 2B, the cylinder 22 can move to the right in the figure while being inclined with respect to the fixed shaft 34.

As a result, as shown in FIG. 6, the guide mechanism 10 and the drive rod 3 are integrally tilted to the retracted position on the frame 18 side on the outer side of the collar frame 1, and the right end portion of the holding member 30 is moved to the stopper member (not shown). Comes to rest when abuts. This tilted state is stably maintained because the center of gravity of the drive rod 3 is present on the frame 18 side with respect to the connecting portion 13a.
Note that the left guide mechanism 10 in FIG. 1 does not need to be tilted in attaching and removing the saddle frame, and thus remains fixed at the guide position. When it is necessary to tilt the left guide mechanism 10 shown in FIG. 1 in attaching and removing the saddle frame, the right guide mechanism 10 can be fixed. Therefore, the first embodiment has an advantage that the guide members 26 and 26 can be tilted to the retracted position on either the right side or the left side as required.

  By the tilting of the guide mechanism 10, the side stay 2 of the collar frame 1 is separated from the guide member 26, and a large space is formed between the guide member 26. Therefore, the eaves frame 1 can be pulled up as it is by the suspending means. In addition, since the hook frame 1 may be lifted upward, the hook frame 1 can be lifted upward by the hanging means when it is released from the clamp 4 before the guide mechanism 10 is tilted.

The new frame 1 carried by the suspending means is lowered from above to the frame mounting position through the space opened by the tilting of the guide mechanism 10. At this position, each collar frame 1 is moved to the left side in FIG. 1, and the left side stay 2 of each collar frame 1 is fitted into each guide groove 27 of the left guide member 26. Next, the right guide mechanism 10 is rotated to the guide position about the connecting portion 13 (a), and the right side stay 2 of each collar frame 1 is fitted into each guide groove 27 of the right guide member 26. Subsequently, the bolt 38 of the half member 36 is tightened to fix the cylinder 22 to the fixed shaft 34, and the right guide mechanism 10 is arranged at the guide position. Further, the side stay 2 and the drive rod 3 are integrated by lowering the clamp 4 and tightening the bolt 5 in a state in which the clamp 4 is fitted to the side stay 2, and the machine work is completed.
(Second Embodiment)

The second embodiment shown in FIG. 7 is obtained by changing the configuration of the holding member 30 of the guide mechanism 10 in the first embodiment.
The holding member 30 includes an L-shaped member 41 and arms 20 and 21 extending in the vertical direction from the L-shaped member 41.

In the L-shaped member 41, the portion to which the arms 20 and 21 are attached is formed in a cylindrical shape, but the portion fitted to the fixed shaft 44 as a support member attached to the frame 18 is as shown in FIG. The upper wall 39 and the vertical wall 40 are formed in an L shape, and the lower part is opened to form a free space. Further, as shown in FIG. 7A, the vertical wall 40 is formed with a long hole 42 extending from the upper right to the lower left in the drawing.
The fixed shaft 44 is formed with an upper horizontal surface 45 and a lateral vertical surface 46 at a portion where the fixed shaft 44 is fitted to the L-shaped member 41.

  When the L-shaped member 41 is fitted to the fixed shaft 44, the upper wall 39 contacts the horizontal surface 45 of the fixed shaft 44, and the vertical wall 40 contacts the vertical surface 46 of the fixed shaft 44. In this state, the holding member 30 is fixed to the fixed shaft 44 by tightening the bolts 43 into the screw holes of the fixed shaft 44 through the long holes 42. Therefore, the guide mechanism 10 is set at the guide position, and can guide the vertical movement of the eaves frame 1 during operation of the loom.

As with the first embodiment, the hook frame 1 is attached and detached when performing the machine work. After removing the clamp 4 from the side stay 2, the bolt 43 is loosened and the guide mechanism 10 is tilted toward the frame 18 side. . Since the lower portion of the L-shaped member 41 is opened, the vertical position change due to tilting is allowed, and the guide members 26 and 26 fixed to the arms 20 and 21 are tilted to the retracted position as in the first embodiment. The Since the bolt 43 is fitted in the long hole 42 formed obliquely, the L-shaped member 41 is allowed to move to the frame 18 side while tilting.

The first link 47 is connected to a bracket 48 as a support member fixed to the frame 18 by a bolt 49, and the second link 50 is connected to a bracket 53 fixed to a flat plate 52 by a bolt 54.

  When the guide mechanism 10 is disposed at the guide position during the loom operation, the bracket 48, the first link 47, the second link 50, and the bracket 53 are fixed and integrated by tightening the bolts 49, 51, and 54. To do. Therefore, the guide members 26 and 26 can guide the collar frame 1 in a stable state.

  At the time of machine setting, the clamp 4 is removed from the side stay 2 in the same manner as in the first embodiment, and then the bolts 49, 51, 54 are loosened, so that the first link 47 and the first link 47 are connected to each other between the bracket 48 and the first link 47. The two links 50 and the second link 50 and the bracket 53 are respectively rotatable. Therefore, when the guide mechanism 10 is tilted to the frame 18 side, the first link 47 and the second link 50 are folded around the bolt 49, so that the drive rod 3 is centered on the connecting portion 13a as in the first embodiment. The guide members 26 and 26 can be moved from the guide position to the retracted position.

In the third embodiment, since the holding member 30 of the guide mechanism 10 is configured using a link, the guide members 26 and 26 can be tilted with a simple configuration.
