Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heald frame guide plate which keeps a constant distance between adjacent heald frames while preventing contact between the heald frames.

[0002]

2. Description of the Related Art A guide plate for a heddle frame is mounted in such a manner as to hold a horizontal beam at one central position of upper and lower horizontal beams or at a plurality of right and left positions.

Conventionally, as shown in FIGS. 5 and 6, this guide plate is separated from the upper and lower sides so as to be attachable and detachable in the vertical direction, and is provided with a pair of front and rear gripping portions 1, 1. In the state in which the cross beam 2 is sandwiched between the both holding portions 1, 1, the end portions 1a, 1a on the opening side of the both holding portions 1, 1 are coupled by the two connecting screws 3, 3. Then, the tension screw 5 screwed into the tension block 4 pulls the tension block 5 in the vertical direction to fix the tension beam 4 to the cross beam 2.

In FIGS. 5 and 6, 6 is a screwdriver insertion hole for screwing the tension screw 5 from the outside, 7 is a hanger mounting groove of the cross beam 2, and 8 is a middle hook hanger mounted in the hanger mounting groove 7. , 9 are the same hanger mounting screws, 1
Reference numeral 0 is a middle hook attached to the hanger 8, and 11 is a carrier rod to which a heald (not shown) is attached.

[0005]

However, the conventional guide plate has the following drawbacks.

(A) Mounting work Two types of screwing operations are required at the time of mounting to the cross beam 2, that is, a stop operation by the connecting screws 3 and 3 and a tensioning operation by the tensioning screw 5, and screwing in these two types of operations. The directions are different from each other,
Moreover, since the direction of the cross beam 2 has to be changed for each screwing operation because it is also different from the screwing direction of the hanger mounting screw 9, the work of mounting the guide plate becomes troublesome, and the efficiency of assembling the heddle frame is poor. Was becoming.

(B) Attached state Since a gap is created between the tension block 4 and the upper surface of the horizontal beam,
Due to this gap, the guide plates are attached in a twisted or tilted state, which sometimes deteriorates the contact state between the guide plates during operation of the loom.

(C) Cost A total of three screws 3, 3, 5 and a tension block 4, and insert nuts 12, 12 are required at one end of the holding portions 1, 1 on the opening side, and the number of parts is large. To be, insert processing of nuts 12 and 12, this nut 1
2 and 12 screw through holes (see FIG. 4) 13, 13
Since a lot of detailed processing such as the processing of No.1 and the screw hole of the tension block 4 is required, and the processing becomes troublesome, the cost is high.

Therefore, the present invention provides a heddle frame which can be easily attached to a cross beam in a proper state without being twisted or tilted, has a small number of parts, is easy to process, and is low in cost. A guide plate is provided.

[0010]

According to a first aspect of the present invention, there is provided a guide plate mounted on a horizontal beam of a heddle frame, wherein a front wall and a rear surface wall which sandwich the horizontal beam from both front and rear sides, and carrier rod mounting on the horizontal beam. An inner horizontal wall that touches the end face on the side,
A lateral beam fitting portion that is externally fitted to the lateral beam is formed by the outer horizontal wall that is in contact with the end surface on the side opposite to the carrier rod mounting side of the lateral beam, and on the inner surface of the inner horizontal wall of the lateral beam fitting portion,
A projecting wall that fits into a hanger mounting groove provided on the end surface of the cross beam on the carrier rod mounting side is provided, and a screw hole into which a tension screw is screwed is provided so as to extend across the projecting wall and the inner horizontal wall. It is something that is done.

According to a second aspect of the present invention, in the structure of the first aspect, the convex wall is provided over the entire width of the guide plate.

According to a third aspect of the present invention, in the structure of the first or second aspect, a boss portion is provided on the outer surface of the inner horizontal wall so that the screw hole extends through the boss portion, the inner horizontal wall and the convex wall. It was provided by.

[0013]

According to the above construction, the guide plate can be attached to the horizontal beam by screwing the tension screw in the state where the horizontal beam fitting portion is fitted onto the horizontal beam and pressing the tip of the tension screw against the inner surface of the hanger attachment groove.

That is, it is not necessary to operate a screw for stopping the opening of the both holding portions as in the prior art, and it can be easily attached only by a screw operation for tensioning.

Further, the tension block and the part for preventing the opening are not required, and various processes such as the insert process of the nut are also unnecessary.

Moreover, the clearance due to the tension block is eliminated, and the convex wall is fitted into the hanger mounting groove to control the twist and inclination of the guide plate (in particular, the convex wall is provided over the entire width of the guide plate. According to the configuration of claim 2, the restricting action is strong), so that a proper mounting state can be obtained.

Further, since the screw hole is provided over the convex wall and the inner horizontal wall, the length of the screw hole can be made sufficiently long. Therefore, unlike the case where the screw hole is provided only on the inner horizontal wall, the screw hole is too short and the strength against screwing is insufficient, and there is no fear that the screw groove is crushed.

In particular, according to the third aspect of the invention, since the screw hole length can be increased by the boss portion, the anti-screw strength can be further increased.

[0019]

Embodiments of the present invention will be described with reference to FIGS.

The guide plates are symmetrically attached to the upper and lower horizontal beams, but here, the upper guide plate A attached to the upper horizontal beam 2 will be described as an example.

The guide plate A includes a front wall 21 and a rear wall 2.
2, a top surface wall 23, and a bottom surface wall (inner horizontal wall) 24 are formed into a flat frame shape that is closed in the front and rear and in the top and bottom.

The guide plate A includes a front wall 21 and a rear wall 2.
A horizontal partition wall (outer horizontal wall) 25 is provided between the upper portions of the two, and the partition wall 25, the front and rear surface walls 21 and 22, and the lower surface wall 24 form a horizontal beam fitting portion 26 through which the horizontal beam 2 can pass. Has been formed.

Reference numerals 27 and 27 are middle partition walls provided between the front wall and the rear wall 21, 22 between the partition wall 25 and the upper wall 23.

Further, a convex wall 28 is vertically projected over the entire width of the guide plate at the central portion in the thickness direction of the guide plate inside the lower surface wall 24 (upper surface side).

On the other hand, on the outer side (lower surface side) of the lower surface wall 24,
A square block-shaped boss portion 29 is provided in the center portion in the width direction, and a screw hole 31 into which a tension screw 30 is screwed is passed through the boss portion 29, the lower surface wall 24, and the convex wall 28 in the vertical direction. It is provided.

Reference numerals 31 and 31 are reinforcing ribs provided between the boss portion 29 and the lower surface wall 24.

This guide plate A is attached to the horizontal beam 2 at the stage of assembling the heddle frame.
When it is attached to the cross beam 2, the cross beam fitting portion 26 is fitted onto the cross beam 2 from one end side thereof.

At this time, the front wall 21 is in contact with the front surface of the horizontal beam, the rear wall 22 is in the rear surface thereof, the lower wall 24 is in contact with the lower end surface of the horizontal beam (the end surface on the carrier rod mounting side), and the partition wall 25 is in contact with the upper end surface of the horizontal beam. Moreover, the convex wall 28 fits into the hanger mounting groove 7 of the lateral beam 2.

As is well known, the hanger mounting groove 7 is formed in a shape in which the lower surface opening side is narrowed in a neck shape, and the convex wall 28 is fitted into the neck portion 7a (shown in FIG. 3).

Next, after positioning the guide plate A at a predetermined position, the tension screw 30 is screwed into the screw hole 31, and the tip thereof is pressed against the inner surface 7b of the hanger mounting groove 7.

As a result, the guide plate A is pulled downward (the horizontal beam 2 is pushed upward) and fixed to the horizontal beam 2.

According to this guide plate A, as described above, the screw operation for stopping the opening of the both holding portions, which is required in the conventional guide plate, is not necessary, and the horizontal beam 2 is attached to the cross beam 2 only by the tension operation by the tension screw 30. Can be easily installed.

Moreover, since the gap due to the tension block unlike the conventional guide plate is eliminated and the convex wall 28 is fitted into the hanger mounting groove 7, the movement of the guide plate A at the time of mounting is restricted. The guide plate A can be properly mounted without being twisted or tilted in the mounted state.

Further, the screw hole 31 is formed in the boss portion 29 and the lower surface wall 2.
4 and the convex wall 28, the screw hole 3
The length of 1 can be made sufficiently long. Therefore, unlike the case where the screw hole 31 is provided only in the lower surface wall 24, the hole length is too short, the strength against screwing is insufficient, and there is no fear that the screw groove is crushed.

According to this guide plate A, after assembly,
Although it cannot be removed from the horizontal beam 2, according to many years of experience of the inventor, since the life of the heald frame and the life of the guide plate are almost the same, it is not necessary to remove the guide plate A from the horizontal beam 2 in fact. In addition, there is no inconvenience.

On the other hand, the lower guide plate has the same configuration as the upper guide plate A in the upside-down relationship, and is attached to the lower horizontal beam in the same manner.

By the way, in the above embodiment, the convex wall 28 is provided over the entire width of the guide plate, but the convex wall 28 may be provided only in the central portion in the width direction.

Alternatively, the boss portion 29 may not be provided, and the screw hole 31 may be provided across the lower surface wall 24 and the convex wall 28. Even in this case, the required length of the screw hole 31 (against the screwing strength) can be secured by making the height dimension of the convex wall 28 sufficiently large.

[0039]

As described above, according to the guide plate of the present invention, the front beam, the rear wall, the inner horizontal wall, and the outer horizontal wall form a horizontal beam fitting portion that is closed in the front and rear and up and down, and the inner horizontal A state in which a convex wall that fits into the hanger mounting groove of the horizontal beam is provided on the inner surface of the wall, and a screw hole for tension is provided across the convex wall and the inner horizontal wall, and the horizontal beam fitting portion is externally fitted to the horizontal beam. Since it is configured to be attached to the cross beam by screwing in the tension screw with, the following effects can be obtained.

(I) Installation work The screw operation for stopping the opening of the both holding parts unlike the conventional guide plate is not required, and only the screw operation for tension is required. Moreover, the screwing direction of this tension screw is the hanger. Since it is the same as the screwing direction of the mounting screw, it is not necessary to change the direction of the horizontal beam each time the screwing operation is performed, so that the work of mounting the guide plate is simplified and the efficiency of assembling the heddle frame can be improved.

(Ii) Mounting state No gap is created by the tension block, and twisting or tilting of the guide plate is restricted by fitting the convex wall into the hanger mounting groove (especially, the convex wall is spread over the entire width of the guide plate. According to the second aspect of the present invention provided by means of the above, the restricting action works strongly), so that an appropriate mounting state can be obtained without fear of being twisted or tilted.

(Iii) Cost Since the tension block and the component (insert nut) for stopping the opening, which were required in the conventional guide plate, are not required, the number of components can be reduced, the insert processing of the nut, and the threading corresponding to this nut. Much finer processing such as drilling holes and threading holes for tension blocks is not required, and the process is simple, so costs can be reduced.

Further, since the screw holes for tensioning are provided so as to straddle the convex wall and the inner horizontal wall, the length of the screw holes can be made sufficiently long. Therefore, unlike the case where the screw holes are provided only on the inner horizontal wall, there is no fear that the screw holes are too short and the anti-screw strength becomes insufficient.

In particular, according to the third aspect of the invention, since the screw hole length can be increased by the boss portion, the anti-screw strength can be further increased.
