Description

  The present invention provides a weaving machine, in particular, a plurality of shelving frames, an opening driving device for vertically driving each of the shedding frames up and down, and connecting the opening driving device and the heald frames together A shed frame height position adjustment device for use in a loom including a drive transmission mechanism including a drive transmission mechanism configured to be able to change the support height of the heald frame in the vertical direction, the loom comprising: The present invention relates to a shed frame height position adjustment device for a loom used at the time of adjusting the height position of the shed frame which is performed before the start of operation of the above.

  The opening device in the loom as described above is, for example, as shown in FIG. The opening device is a plurality of drive transmission mechanisms provided corresponding to each heald frame, and includes a drive transmission mechanism connecting the corresponding heald frame and the rocking lever in the opening drive device. Each of the drive transmission mechanisms is configured to convert the reciprocating rocking motion of the rocking lever in the opening drive device into the vertical movement of the trouser frame. In addition, each drive transmission mechanism includes a pair of rod-shaped support members, one end of which is connected to the corresponding rod frame in a form attached to the lower end of the rod frame. Therefore, each shed frame is in a state of being supported by a pair of support members in the corresponding drive transmission mechanism, and its height position is determined by the length of the support members.

  In the loom, along with the change of the woven fabric, etc., adjust the height position of each shed frame in the opening device according to the weaving of the fabric after the change at the adjustment operation performed before the start of the operation of the loom. An operation (hereinafter, also referred to as “height position adjustment operation”) may be performed. And the adjustment of the height position of each shed frame in the loom provided with the above-mentioned opening device is the height of the shed frame after changing (adjustment) the length of a pair of support members that support the shed frame It is done by making it correspond to the position.

  More specifically, each support member in each drive transmission mechanism is constituted by a connecting rod connected to the heald frame at one end and a cylindrical support into which the other end of the connecting rod is inserted. And each support member can change the length (whole length) as a whole by changing the insertion amount of the connection rod with respect to a support body. Also, the fixing of the position of the connecting rod to the support is performed by means of a fixing screw screwed into the support. That is, the entire length (the insertion amount of the connecting rod with respect to the support) can be changed by loosening the fixing screw, and the entire length can be determined by tightening the fixing screw. ing. And since each support member supports the heald frame in the vertical direction as described above, in the opening device, the height position of the heald frame is adjusted along with the change of the entire length of the support member. Ru.

  Therefore, when adjusting the height position of the heddle frame, the fixing screw is loosened to make it possible to change the entire length of the support member that supports the heddle frame to be adjusted, and the height of the heddle frame in that state After changing the cross position to a position according to the next weaving, an operation of tightening the fixing screw and determining the height position of the heald frame (the entire length of the support member) is performed.

  By the way, in the opening device, each shed frame is supported by the support member in the corresponding drive transmission mechanism as described above, in other words, the weight of each shed frame is received by the support member in the corresponding drive transmission mechanism It is in a state of being Therefore, when adjusting the height position of the heald frame as described above, if the fixing screw in the support member is loosened without supporting the heald frame in the vertical direction, the heald frame loses its support and falls by weight. Therefore, the height position adjustment work of the heddle frame must be performed at least while supporting the heddle frame, and then the fixing screw located below the heddle frame must be loosened and tightened. , The work has become a thing that requires two or more workers.

  On the other hand, there are apparatuses disclosed in Patent Document 1 and Patent Document 2 as conventional techniques for facilitating the height position adjustment operation of the heald frame.

  Although the device disclosed in Patent Document 1 is applied to a type different from the above-described opening device on which the present invention is premised, a shelving frame is provided at the connecting portion between the rod and the shelving frame in the drive transmission mechanism. A mechanism for adjusting the height position of the

  Further, the device disclosed in Patent Document 2 is not incorporated in the opening device as in the device of Patent Document 1, but is solely present as a tool for height position adjustment work of the heald frame, At the time of height position adjustment operation of the heald frame, it is installed in a form to be placed on the fixed part of the loom. And the device of the patent document 2 is equipped with the engagement means engaged with the side stay of the heald frame, and in the state mounted on the fixed part of the loom, the heald frame and the coupled state by the engagement means And the holding frame can be held (the holding frame can be supported), and the height position of the holding frame can be changed by displacing the engagement means in the vertical direction by the elevating mechanism ( Adjustment).

  However, the device of Patent Document 1 is configured such that the mechanism is incorporated in each shed frame with respect to the opening device, so that the structure of the opening device becomes complicated and the problem of causing an increase in manufacturing cost It is included. Moreover, in the case of the structure, since the weight of the portion (including the heald frame) moving up and down during the opening movement increases, the adoption of the structure incorporating the mechanism can also be a factor that hinders the speeding up of the loom.

  On the other hand, the device of Patent Document 2 is provided as a tool independent of the opening device, and is connected to the heald frame only at the time of adjusting the height position of the heald frame, so the Patent Document described above The problem of concern in the device 1 does not occur. However, in the case of the device of this patent document 2, the engagement means engaged with the heald frame is vertically displaced as described above to adjust the height position of the heald frame, but the engagement means The configuration for engagement with the heald frame (engagement configuration) causes the following problems.

  First, Patent Document 2 discloses a gripping mechanism (gripping device) that grips the side stay in the heald frame in the front-rear direction (the thickness direction of the heald frame) as the engagement configuration. Specifically, the gripping mechanism includes a main body portion, a fastening portion, and a clamp portion, and by clamping an external screw included in the fastening portion, the side stay is gripped by the main body portion and the clamp portion. It will be in the engaged state. However, in the case of such a gripping mechanism that grips the side stay in the front-rear direction, the heald frame is vertically displaced according to the displacement of the gripping mechanism (engagement means) unless the gripping force is strong (raising and lowering Therefore, in order to realize the strong gripping force, it is necessary to tighten a male screw considerably. Therefore, the device of Patent Document 2 places a heavy burden on the worker in the operation for engaging the engagement means with the heald frame. Further, when the loom is wide, the weight of the shed frame is large. Therefore, in the case of engagement by gripping as described above, the shed frame may not be reliably lifted and lowered according to the displacement of the engagement means.

  Further, according to Patent Document 2, as the engagement configuration, an engagement pin provided on the engagement means is engaged with an engagement hole formed on the side stay of the shed frame separately from the gripping mechanism as described above. A configuration is also disclosed. However, in the case of such a configuration, no such engagement hole is formed in a generally used heald frame, so when using the apparatus of Patent Document 2 having that configuration for an existing loom, It is necessary to carry out new hole processing to the weir frame. Further, in the case where the shed frame to be manufactured newly is one in which such an engagement hole is formed, the number of processing steps is increased by that amount, and the manufacturing cost is increased. Furthermore, although the heald frame is driven in the vertical direction at high speed during weaving of the loom, there is a possibility that the strength of the heald frame may be reduced as a result of forming such an engagement hole in the side stay.

  The support base 51 is formed of a single plate material in the present embodiment, and is a member that has a substantially rectangular shape when viewed in the plate thickness direction. More specifically, the support base 51 has a guide portion 51a having an elongated rectangular shape and an insertion portion 51b positioned on one end side in the longitudinal direction of the guide portion 51a when viewed in the plate thickness direction. However, the insertion portion 51b has a dimension larger than the guide portion 51a in the width direction (direction orthogonal to the longitudinal direction on the plate surface). And the insertion part 51 is formed in the state which made the center correspond with respect to the guide part 51a regarding the said width direction, and it is formed so that the edge of the said one end side of the guide part 51a may be followed. Accordingly, the insertion portion 51a is formed to project on both sides of the guide portion 51a in the width direction. In other words, the insertion portion 51a has portions (protruding portions) that protrude to both sides in the width direction with respect to the guide portion 51a.

  The support base 51 extends in a direction (= the plate thickness direction) substantially orthogonal to the plate surface of the guide portion 51a on the other end side of the guide portion 51a (the side opposite to the one end side in the longitudinal direction). It has the abutment part 51c formed in this way. And, in the present embodiment, the abutment portion 51c is formed to be continuous with the end edge on the other end side of the guide portion 51a.

The bolt member 52b1 is a screw member in which a male screw is cut across the entire shaft extending from the head, and the shaft is a screw which is assumed during the height position adjustment operation of the heald frame 10. The length dimension is larger than the adjustment amount (displacement amount) of the frame 10.

  Further, the support block 52b2 is a rectangular parallelepiped block-like member, and is attached to the end (the end opposite to the head) of the bolt member 52b1 to configure the displacement portion 52b together with the bolt member 52b1. It is. However, in the attached state, the support block 52b2 is in a state in which the long side direction of the side surface (four surfaces having the same long side length) is aligned with the axial direction of the bolt member 52b1.

  In the present embodiment, the support block 52b2 is a mounting hole 52bx which is opened at one of the both end surfaces (two surfaces excluding the side surface), and is mounted with an internal thread cut at its inner peripheral surface. Holes 52bx are formed. The mounting of the support block 52b2 on the bolt member 52b1 is performed by screwing the bolt member 52b1 into the mounting hole 52bx of the support block 52b2. Accordingly, the support block 52b2 can be attached and removed with respect to the bolt member 52b1.

  Further, the support block 52b2 is formed with a through hole 52by which is open at two parallel side surfaces of the side surfaces and is parallel to the other side surface to penetrate the support block 52b2. Further, in the present embodiment, two through holes 52 by are formed separately in the long side direction of the side surface. Furthermore, each through hole 52by is formed as a female screw hole in which a female screw is cut on the inner peripheral surface.

  In addition, screw members 52b3 are screwed into the respective through holes (female screw holes) 52by. That is, two screw members 52b3 and 52b3 are attached to the support block 52b2 by being screwed into the through holes 52by. However, each screw member 52b3 is in a state of projecting from the side surface of the support block 52b2 in the attached state. And according to the structure, the hook part for supporting the raising / lowering member 53 will be in the state formed in the displacement part 52b like the after-mentioned. In other words, the displacement portion 52b including the support block 52b2 has a hook portion for supporting the elevating member, and the screw member 52b3 attached to the support block 52b2 functions as the hook portion .

  Further, in the support block 52b2, the dimension in the short side direction in the side surface parallel to the through hole 52by of the side surface is substantially the same (slightly larger) as the thickness of the heald frame 10 (frame steel 11). There is.

  When assembling the adjustment mechanism 52 having such a configuration to the support base 51, first, the wing nut 52a is screwed into the bolt member 52b1. Then, the bolt member 52b1 in a state in which the wing nut 52a is screwed into the insertion hole 51c1 of the abutment 51c of the support base 51 is inserted from the tip end side. Then, the support block 52b2 is attached to the bolt member 52b1 as described above. As a result, the adjusting mechanism 52 (displacement portion 52b) is assembled to the support base 51 by being inserted through the insertion hole 51c1 of the support 51c in the bolt member 52b1. Incidentally, the insertion hole 51c1 in the support base 51c of the support base 51 has a size that allows passage of the shaft of the bolt member 52b1 and displacement within the hole but does not allow passage of the wing nut 52a and the support block 52b2. It has become.

  In the assembled state as described above, in the support block 52b2, the side surface opposite to the side surface to which the screw member (hooking portion) 52b3 is attached is opposed to the plate surface of the guide portion 51a in the support base 51. It will be in the state. That is, in the assembled state, the openings of the through holes 52 by and 52 by in the support block 52 b 2 are opposed to the long holes 51 a 1 formed in the guide portion 51 a in the support base 51.

  Further, in the displacement portion 52b of the present embodiment, in the assembled state, the screw member 52b4 is inserted from the side opposite to the support block 52b2 side with respect to the long hole 51a1 in the guide portion 51a of the support base 51. The support block 52b2 is configured to be attached by screwing from the side surface on the opposite side. However, in the attachment state of the screw member 52b4 to the support block 52b2, the distance between the opposite side surface of the support block 52b2 and the head of the screw member 52b4 is slightly smaller than the thickness of the guide portion 51a of the support base 51. It is supposed to be large. The dimension in the width direction of the elongated hole 51a1 in the guide portion 51a is slightly larger than the diameter of the shaft portion of the screw member 51b4, and the shaft portion of the screw member 51b4 extends in the elongated hole 51a1 in the elongated hole 51a1. It is allowed to shift to

  Due to the configuration, in the assembled state, the displacement of the support block 52b2 (displacement portion 52b) in the extension direction of the long hole 51a1 in the support base 51 (= longitudinal direction of the guide portion 51a) is the long hole 51a1 and the screw member 51b4. , And the support block 52b2 can not be largely separated from the guide portion 51a of the support base 51 in the plate thickness direction.

  As described above, in the installation state of the frame height adjusting device 50 at the time of height position adjustment operation of the heald frame 10, the guide portion 51a of the support base 51 is upward from the installation portion 51d on the adjacent heald frame 10b. It will be in the state extended to the direction. Therefore, in the installed state, the displacement portion 52b of the adjustment mechanism 52 is supported by the abutment 51c of the support base 51 with the wing nut 52a screwed to the bolt member 52b1. That is, in the installed state, the wing nut 52a in the adjustment mechanism 52 is placed on the abutment 51c of the support base 51 while supporting the weight of the displacement portion 52b and the like. Further, when adjusting the height position of the heald frame 10, the weight of the adjustment shed frame 10a is also applied to the wing nut 52a via the raising and lowering member 53, as described later.

  Thus, at the time of height position adjustment operation of the heald frame 10, the wing nut 52a as the adjustment portion in the adjustment mechanism 52 is placed on the abutment portion 51c in the support base 51, and the downward displacement is supported. While being in a state of being restricted by the base portion 51c, the weight of the displacement portion 52b, the heald frame 10, etc. is received and pressed against the abutment portion 51c. That is, the displacement of the wing nut 52a in the vertical direction (the extending direction of the guide portion 51a in the support base 51) is limited.

  Further, in this state, when the screwing position of the hinge nut 52a and the bolt member 52b1 in the axial direction of the bolt member 52b1 is changed by rotating the hinge nut 52a, the extending direction of the hinge nut 52 ( The bolt member 52b1 is displaced in the extending direction as the displacement in the vertical direction is limited. That is, in the installation state, the frame height adjustment device 50 rotates the wing nut 52a as the adjustment portion in the adjustment mechanism 52 so that the displacement portion 52b including the bolt member 52b1 becomes the guide portion 51a of the support base 51. It is configured to be displaced in the extending direction.

  The raising and lowering member 53 is formed of a bar (round bar-like member) in the present embodiment. In addition, the said bar material for forming the raising / lowering member 53 is an thing of the outer diameter which can be penetrated to the said gap between several ladle frames 10 with which a loom is equipped.

  The elevating member 53 has a configuration in which the end portion of the bar is bent, and the hooking portion 53a formed at one end thereof and the other end (the side opposite to the hooking portion 53a side) And a support 53b formed on the end of the The hooking portion 53a is a portion for setting the hook frame 10 in a state of being hooked to the elevating member 53. Further, the support portion 53 b is a portion for making the elevating member 53 supported by the displacement portion 52 b of the adjustment mechanism 52. And the raising / lowering member 53 becomes a structure by which the hook part 53a and the support part 53b were connected by the rod-shaped base 53c.

  More specifically, the hooking portion 53a is formed by bending a portion on one end side of the rod in two directions in the same direction, and each portion is substantially viewed from the side. It has a U-shape. In addition, in the hook portion 53a, the bending angles at the two bending portions are substantially perpendicular. Therefore, of the two bent portions of the hook portion 53a, the portion on the tip end side of the bent portion on the tip end side is the tip portion, and the portion on the base 53c side than the bent portion on the base 53c side is the base portion In the case of the side portion, the tip end portion and the base side portion of the hook portion 53a are substantially parallel. In addition, the distance between the tip portion and the base portion, that is, the length of a portion (intermediate portion) between the tip portion and the base portion and extending in a direction substantially perpendicular to the base 53c is It is substantially the same as the thickness of the heald frame 10 (frame steel 11), and is capable of receiving the frame steve 11 of the heald frame 10 between the tip end portion and the base side portion.

  Further, the support portion 53b is formed by curving a portion on the other end side of the bar in an arc shape. However, the support portion 53 b is formed such that the arc portion formed by the bending can be engaged with the shaft portion of the screw member 52 b 3 as a hooking portion in the displacement portion 52 b of the adjustment mechanism 52. In other words, the support portion 53b is formed such that the arc radius of the inside of the arc portion is substantially the same as the radius of the shaft portion of the screw member 52b3. Further, the support portion 53b is formed such that the bending direction thereof is substantially orthogonal to the intermediate portion of the hook portion 53a when viewed in the axial direction of the base portion 53c.

  And the raising / lowering member 53 of such a structure is the adjustment supported by the support base 51 in the said installation state at the time of use of the frame height adjustment apparatus 50, ie, the height position adjustment operation of the shed frame 10. With respect to the hooking portion 52b3 of the mechanism 52 (displacement portion 52b), the support portion 53b is hooked. Then, in that state, the elevating member 53 is in a state of being supported by the displacement portion 52b, and in a state of being supported by the support base 51 via the adjustment mechanism 52 including the displacement portion 52b. ing.

  As described above, the bending direction of the support portion 53b of the elevating member 53 is substantially orthogonal to the intermediate portion of the hook portion 53a when viewed in the axial direction of the base 53c. Therefore, in the state where the elevating member 53 is supported as described above, the intermediate portion of the hooking portion 53a is substantially parallel to the thickness direction of the support base 51. And, at the time of height position adjustment work of the heald frame 10, the raising and lowering member 53 is oriented such that the intermediate portion in the hooking portion 53a is positioned below the support block 52b2 in the adjustment mechanism 52 as described above. The hook portion 52b3 is hung.

  Further, at the time of height position adjustment operation of the heald frame 10, in the state where the raising and lowering member 53 is supported as described above, the downward surface of the upper frame stub 11 of the adjustment shed frame 10a is latched at the hooking portion 53a. It is supposed to be in the closed state. Also, in the present embodiment, the downward surface of the upper frame stub 11 is the lower surface of the upper frame stub 11. Further, the hooking state of the lower surface by the hooking portion 53a is achieved by receiving the upper frame stub 11 in the hooking portion 53a as described above. Accordingly, the elevating member 53 is supported by the support portion 53b as described above with respect to the displacement portion 52b of the adjustment mechanism 52 positioned above the upper frame stub 11, while the upper frame stub 11 is received by the hooking portion 53a. In other words, the length of the base portion 53c between the support portion 53b and the hooking portion 53a is set to be larger than the dimension of the frame stub 11 in the vertical direction. .

  The frame height adjusting device 50 having the above-described configuration is used at the time of the height position adjustment operation of the shed frame 10 through the following procedure by the operator.

  First, as procedure 1, the frame height adjustment device 50 is placed on the upper surface of the upper frame stub 11 in the adjacent weir frame 10b on the lower surface of the pair of installation portions 51d of the support base 51 with the lifting member 53 removed. It will be installed in a form. The orientation of the frame height adjustment device 50 at the time of installation is such that the insertion portion 51b of the support base 51 is located between the adjacent shed frame 10b and the adjustment shed frame 10a in the front-rear direction. Therefore, in the installed state, the abutment 51c of the support base 51 of the frame height adjustment device 50 and the displacement portion 52b of the adjustment mechanism 52 are positioned above the adjustment collar frame 10a (FIG. 2).

  Next, in step 2, with the elevating member 53 positioned on the opposite side of the base 53c with respect to the adjustment collar frame 10a with respect to the adjacent collar frame 10a, the upper frame of the adjustment collar frame 10a is fixed to the hook portion 53a. The lower part of 11 is accepted.

  In this procedure 2, as shown in FIG. 2, there is a weir frame 10 on the opposite side of the adjustment weir frame 10a in the front and rear direction with respect to the control weir frame 10a, and the upper frame in the weir frame 10 on the opposite side When the Steve 11 is in a position facing the upper frame Steve 11 in the adjustment rod frame 10a, the procedure 2 is to raise and lower the gap between the opposite rod frame 10 and the adjustment rod frame 10a. This is done by inserting the member 53.

  Specifically, in the procedure 2, first, the elevating member 53 is inserted into the gap from the side of the hooking portion 53a with the intermediate portion of the hooking portion 53a directed to the lateral direction of the hook frame 10 . Next, with the hooking portion 53a positioned below the upper frame stub 11 of the adjustment rod frame 10, the lifting member 53 is rotated about the axis of the base 53c, and the intermediate portion is the upper frame rib of the adjustment rod frame 10a. It is in a state of facing the lower surface of 11. Then, in this state, by lifting the raising and lowering member 53, the lower portion of the upper frame stub 11 is received by the hooking portion 53a.

  Then, as the procedure 3, as described above, the raising / lowering member 53 which receives the upper frame steel 11 of the adjustment collar frame 10a in the hooking portion 53a, the hooking portion in the adjustment mechanism 52 (displacement portion 52b) 52b3 to be supported by the adjustment mechanism 52. When performing this procedure 3, the position (height position) in the vertical direction of the hooking portion 52b3 (support block 52b2) in the adjustment mechanism 52 is the hooking portion of the upper frame steel 11 of the adjustment collar frame 10 as described above. It adjusts so that the height position of the support part 53b in the raising / lowering member 53 of the state received to 53a and the height position of hook part 52b3 may correspond.

  Incidentally, in the frame height adjustment device 50 of the present embodiment, the adjustment mechanism 52 (displacement portion 52b) is the two hook portions 52b3 attached to the support block 52b2 so as to be spaced apart in the vertical direction in the installed state. , 52b3. This configuration is such that one of them can be selectively used depending on the dimension or the like in the vertical direction of the upper frame stub 11 in the adjustment shed frame 10a. Therefore, the number of hooks 52b3 is not necessarily two, and may be only one. Further, the hooking portion 52b3 is not limited to the one constituted by the screw member as described above, but is constituted by a pin or the like provided by being inserted into a hole formed in the support block 52b. It is also good. The same applies to the configuration (screw member 52b4) for guiding the displacement of the displacement portion 52b (support block 52b2) in the vertical direction.

  Then, according to the procedure 3 as described above, the upper frame stub 11 of the adjusting rod frame 10a and the adjusting mechanism 52 of the frame height adjusting device 50 are connected by the raising and lowering member 53. Therefore, by performing the above-described procedures 1 to 3, the frame height adjusting device 50 can adjust the height position of the adjustment shed frame 10a.

  In addition, when adjusting the height position of the adjustment rod frame 10a, as described above, the entire length of the support member 21 in the drive transmission mechanism 20 supporting the adjustment rod frame 10a can be changed. In other words, the fixing screw 21c for fixing the position of the connecting rod 21a relative to the support 21b is loosened. Along with that, the support of the adjustment rod frame 10a by the support member 21 is lost. However, as described above, the adjustment rod frame 10a is received by the hooking portion 53a of the raising and lowering member 53 in the frame height adjusting device 50 in the upper frame stub 11, and the middle portion of the hooking portion 53a in the vertical direction A portion is in contact with the lower surface of the upper frame stub 11. As a result, even if the support by the support member 21 is lost, the hooking portion 53a (the intermediate portion) holds the lower surface of the upper frame stub 11. Therefore, the adjustment rod frame 10a is supported by the frame height adjustment device 50, in other words, supported by the adjacent rod frame 10b on which the frame height adjustment device 50 is installed via the frame height adjustment device 50. It will be

  Then, in this state, the wing nut 52a as the adjusting portion in the adjusting mechanism 52 is rotated, whereby the displacement portion 52b is displaced in the vertical direction (the extending direction of the guiding portion 51a), and the displacement portion 52b The height position of the adjustment rod frame 10a connected by the raising and lowering member 53 is changed. Then, when the adjustment collar frame 10a reaches a desired height position, the fixing screw 21c of the support member 21 in the drive transmission mechanism 20 is tightened, and the height position is determined. Incidentally, the height position of the adjustment rod frame 10 is set based on, for example, the upper surface of the rod frame guide 40, and while changing the height position as described above, from the reference to the upper surface of the upper frame stub 11 by scale etc. Adjusted while measuring the distance of

  In the above, one embodiment (example) of the present invention has been described, but the shed frame height position adjustment device of the present invention is not limited to the one described in the above embodiment, and the following embodiments The implementation in (Modification) is also possible.

  (1) In the above embodiment, the adjustment mechanism is configured by the combination of the wing nut 52a as the adjustment part, the bolt member 52b1 and the support block 52b2, but the shelving frame height position adjustment device according to the present invention The adjustment mechanism in is not limited to such a configuration, and may have a configuration as shown in FIG. 4, for example. The frame height adjusting device 60 shown in FIG. 4 adopts a feed screw mechanism as an adjusting mechanism. The details of the configuration are as follows.

  In the frame height adjustment device 60, the support base 61 has a guide portion 61a and an insertion portion 61b similar to the support base 51 in the frame height adjustment device 50 of the embodiment, and the guide portion 61a and the insertion portion 61b An installation portion 61 d is formed so as to extend in the thickness direction of the guide portion 61 a at the boundary portion (one end side of the guide portion 61 a in the longitudinal direction). Further, in the guide portion 61a, a long hole 61a1 extending in the extending direction (longitudinal direction) of the guide portion 61a is formed similarly to the support base 51 of the embodiment.

  Further, the support base 61 has a receiving portion 61c formed to extend in the plate thickness direction on the other end side of the guide portion 61a (the side opposite to the one end side in the longitudinal direction). However, with respect to the thickness direction, the direction in which the receiving portion 61c extends is the reverse of the supporting portion 51c of the support base 51 in the embodiment, and the receiving portion 61c is the same as the mounting portion 61d with respect to the guiding portion 61a. It is in the direction of the side. Further, an insertion hole 61c1 through which a feed screw 62a of an adjustment mechanism 62 described later can be inserted is formed in the receiving portion 61c. The receiving portion 61c functions as a position restricting portion that restricts the position of the adjusting mechanism 62 in the width direction and the plate thickness direction, similarly to the support 51c of the support base 51 of the embodiment.

  Further, in the frame height adjustment device 60, the support base 61 extends from the end opposite to the side of the guide portion 61a of the installation portion 61d in the plate thickness direction from the rear wall 61e extending in parallel with the insertion portion 61b. Have. That is, the support base 61 has a substantially U-shaped portion (U-shaped portion) including the installation portion 61 d on the other end side of the guide portion 61 a. Then, in the installation state with respect to the adjacent shed frame 10b, the frame height adjustment device 60 sets the coffin in the installation portion 61d in a state where the upper portion of the upper frame stub 11 in the adjacent cotter frame 10b is received inside the U-shaped portion. It will be in the state mounted on the upper frame stub 11 of the frame 10. Further, in the support base 61, unlike the support base 51 of the embodiment, the installation portion 61d is formed not only on both sides of the insertion portion 61b in the width direction but also at the center of the insertion portion 61b. Therefore, the support base 61 has a configuration in which the central installation portion 61 d (hereinafter referred to as “central installation portion 61 d 1” to distinguish from the installation portions 61 d on both sides) faces the receiving portion 61 c in the longitudinal direction. It has become.

  The adjustment mechanism 62 is configured by the feed screw mechanism as described above, and includes a feed screw 62a and a nut member 62b. The feed screw 62a is inserted in the insertion hole 61c1 of the receiving portion 61c of the support base 61 in the direction in which the axis is parallel to the longitudinal direction (the extending direction). Be incorporated. As described above, the receiving portion 61c and the center installation portion 61d1 of the support base 61 are opposed in the longitudinal direction. Thus, in the state where the feed screw 62a is inserted into the insertion hole 61c1 as described above, the leading end of the feed screw 62a can be in contact with the central installation portion 61d1. Then, in the installed state where the guide portion 61a extends in the vertical direction, the feed screw 62a is in a state where its own weight or the like is received by the central installation portion 61d1.

  Further, the nut member 62b has a shape in which two rectangular parallelepiped block-like members are integrally combined, and a rectangular parallelepiped screw portion 62b1 which is a portion to be screwed to the feed screw 62a; It is comprised by the rectangular parallelepiped-shaped mount part 62b2 to which hooking parts 63b3 and 63b3 to which the member 63 is hung are attached. In the frame height adjusting device 60 of this embodiment, the elevating member 63 has the same structure as the elevating member 53 of the frame height adjusting device 50 of the embodiment. Further, the hooking portions 62b3 and 62b3 are also the same as the hooking portion (screw member) 53b3 in the above embodiment, and the attachment state thereof with respect to the nut member 62b (the frame portion 62b2) is also a hooking portion to the support block 52b in the above embodiment It shall be the same as the mounting state of 53b3.

  In the nut member 62b, the screwing portion 62b1 is a female screw hole penetrating in the direction of the long side in parallel with the side surface (four surfaces having the same long side), and the feed screw 62a and the screw A compatible female screw hole is formed. The nut member 62b is screwed with the feed screw 62a in such a manner that the feed screw 62a is screwed into the female screw hole in the screwing portion 62b1. Further, the gantry 62b2 is integrally formed with the screwing portion 62b1 so as to protrude from one of the side surfaces of the screwing portion 62b1.

  In the nut member 62b, in the screwing portion 62b1, the dimension of the short side of the side surface (projecting side surface) from which the mount portion 62b2 protrudes is the width dimension of the long hole 61a1 formed in the guide portion 61a of the support base 61. Also has been formed large. Further, the mount portion 62b2 has a dimension of the short side of the side surface parallel to the projecting side surface of the screwing portion 62b1 substantially the same as the width dimension of the long hole 61a1 of the guide portion 61a, and can be inserted into the long hole 61a1 It is slidable in the extending direction of the long hole 61a1.

  Furthermore, in the frame height adjustment device 60, the nut member 62b is screwed in the screwing portion 62b1 to the feed screw 62a in a state of being inserted into the insertion hole 61c1 of the receiving portion 61c as described above. The projecting side surface of the screwing portion 62b1 faces the guide portion 61a, and the gantry 62b2 is inserted into the long hole 61a1 of the guide portion 61a.

  However, the dimension (protrusion dimension) in the protrusion direction from the screwing part 62b1 of the mount part 62b2 is larger than the plate thickness of the guide part 61a. Therefore, the gantry 62b2 protrudes from the guiding portion 61a to the opposite side of the screwing portion 62b1 when inserted into the long hole 61a1 of the guiding portion 61a as described above. Further, the projection dimension of the gantry 62b2 is set such that the amount of projection from the guide 61a is substantially the same as the thickness of the heald frame 10 (the frame steel 11). In other words, the projecting dimension of the gantry 62b2 is substantially the same as the thickness of the guide frame 61a plus the thickness of the heald frame 10 (the frame steel 11).

  And at the time of height position adjustment work of the heald frame 10, the frame height adjustment device 60 is mounted on the nut member 62b in the adjustment mechanism 62 in a state of being installed on the adjacent heald frame 10b. On the other hand, the raising and lowering member 63 is hung in the same manner as in the above embodiment, and the adjusting collar frame 10a and the nut member 62b are connected by the raising and lowering member 63 to support the adjusting collar frame 10a. Ru. In the state where the adjustment collar frame 10a is supported as such, the weight of the adjustment collar frame 10 or the like is applied to the feed screw 62a via the raising and lowering member 63 and the nut member 62b, and the feed screw 62a It will be in the state pressed against 61d1. Therefore, in that state, the displacement of the feed screw 62a in the vertical direction (the extending direction of the guide portion 61a) is limited. Further, the nut member 62b is in a state in which the rotation is blocked since the mount portion 62b2 is inserted into the long hole 61a1 in the guide portion 61a.

  Therefore, by rotating the feed screw 62a in that state, the screwing position of the feed screw 62a and the nut member 62b changes, and along with that, the nut member 62b is displaced in the extending direction (vertical direction). As a result, the adjustment collar frame 10a connected to the nut member 62b via the elevating member 63 is displaced in the vertical direction, and the height position thereof is adjusted. The displacement of the nut member 62b in the vertical direction is guided by the mount portion 62b2 sliding in the long hole 61a1 of the guide portion 61a.

  Further, in the configuration of the frame height adjusting device 60 as described above, the feed screw 62 a corresponds to the adjusting portion in the adjusting mechanism 62. Accordingly, the male screw portion in the feed screw 62a corresponds to a screw portion in which the displacement portion in the adjustment portion is screwed. Further, the nut member 62 b and the hooking portions 62 b 3 and 62 b 3 attached to the nut member 62 b correspond to displacement portions in the adjustment mechanism 62. Incidentally, in relation to the configuration of the frame height adjustment device 50 of the embodiment, the feed screw 62a corresponds to the wing nut 52a, and the screwing portion 62b1 of the nut member 62b is the bolt member 52b1, and the mount portion 62b2 is It corresponds to the support block 52b2.

  (2) In the example described above, the support base in the frame height adjustment device is formed of a single plate material, but the support base is not limited to such one, and a plurality of support bases are used. It may be formed by combining plate materials.

  For example, in the configuration of the example described above, another plate member functioning as the installation portions 51d, 61d, the abutment portion 51c, and the receiving portion 61c is adhered to the plate members constituting the guide portions 51a, 61a by welding or the like. It may be. Further, in such a case, the abutment portion and the receiving portion 61c do not have to be located at the end of the other end of the guide portions 51a and 61a, and the other of the plate members constituting the guide portions 51a and 61a The support 51c and the receiving portion 61c may be located closer to the installation portions 51d and 61d than the end of the end (FIG. 5).

  Further, as in the support base 71 shown in FIG. 5, a member having a portion corresponding to the guide portion 71a (L-shaped member) and a member having a portion corresponding to the insertion portion 71b (L-shaped member) are combined. It is also possible that the In the support base 71, unlike the support base 51 of the embodiment, the installation portion 71d is configured to be present in the width direction in the existing range of the guide portion 71a.

  (3) In the embodiment and the like, the raising and lowering member in the frame height adjusting device is formed of a round rod-like member, but the raising and lowering member is not limited to such a constitution. It may be formed of a plate material as shown in FIG. In the raising and lowering member 73 in FIG. 6, a portion indicated by reference numeral 73a corresponds to a hooking portion, and a portion indicated by reference numeral 73b corresponds to a support portion. Further, a portion indicated by reference numeral 73c corresponds to the base 53c of the elevating member 53 of the embodiment.

  In the above embodiment, the hooking portion of the elevating member is formed so as to form a substantially U-shape, but the hooking portion is the upper frame stub 11 of the heald frame 10. As long as it can hold down the downward surface of the above, it may have a substantially L shape as shown in FIG. Further, the support portion of the elevating member is not limited to the hook shape as shown in the embodiment and FIG. For example, when the lifting member is formed of a plate material as shown in FIG. 6, a hole penetrating in the thickness direction is formed, a portion including the hole is used as a support portion, and a hook portion of the adjustment mechanism is inserted through the hole. The raising and lowering member may be supported by the adjusting mechanism in a manner as described above.

  Incidentally, in the case where the elevating member is formed of the plate material as described above, the elevating member to the gap between the upper frame steel 11 of the adjustment rod frame 10a and the upper frame steel 11 of the adjacent rod frame 10b. The insertion of H must be done from below the upper frame Steve 11. Therefore, in terms of ease of use, it is preferable to use a lifting member formed of a round bar-like member that can be inserted into the gap from above the upper frame stub 11 as in the embodiment and the like.

When the frame height adjustment device is in a state of supporting the adjustment rod frame 10a, the force to fall the frame height adjustment device toward the adjustment rod frame 10a is the frame height by the weight of the adjustment rod frame 10a, etc. Act on the speed control device. Therefore, in order to cope with the action of such a force, it is preferable that the support base be configured to have at least the insertion portion in the above-mentioned embodiment and the like.

  (5) In the embodiment and the like, at the time of the height position adjustment operation of the adjustment rod frame 10a, the setting position of the frame height adjusting device is set to the rod frame 10 adjacent to the adjustment rod frame 10 in the longitudinal direction 10b) Although it is on the top, the installation position of the frame height adjustment device is not limited to that on the adjacent coffin frame 10b, but may be on another coffin frame 10. For example, in the frame height adjusting device 50 of the embodiment, as shown in FIG. 7A, the direction of the hooking portion 53a is opposite to that of the above embodiment, ie, the hooking portion 53a in the front-rear direction Is directed to the side of the support base 51 opposite to the guide 51a of the support base 52 with respect to the support block 52b2, and the elevating member 53 is hooked on the hook 53b3. With the frame height adjustment device 50 installed on the heald frame 10 (hereinafter referred to as "installation shed frame 10c") located on the side opposite to the adjustment heald frame 10a in the front-rear direction, the adjustment shed frame 10a The upper frame stub 11 can be latched on the hooking portion 53 a of the lifting member 53.

  For example, as shown in FIG. 7B, the frame height adjusting device is configured such that the hooking portion in the adjusting mechanism is more separated from the guiding portion in the support base in the longitudinal direction than the configuration of the embodiment and the like. The frame height adjusting device may be installed on the other shed frame 10 and used.

  The example shown in FIG. 7B is a modification of the frame height adjustment device 60 shown in FIG. 4. In the frame height adjustment device 60 ′, the nut member 62b ′ is the mount portion 62b2 thereof. The projection dimension of 'is formed to be larger than the configuration shown in FIG. 4 (specifically, twice the configuration shown in FIG. 4). In the case of the configuration, in the state where the frame height adjustment device 60 'is installed on the installation shelving frame 10c as described above, the side surface to which the hook portion 62b3' is attached in the mount portion 62b2 'of the nut member 62b' With respect to the direction, the upper frame stub 11 of the adjustment rod frame 10a is positioned substantially at the same position as the surface on the side opposite to the adjacent rod frame 10b side. Therefore, in the state where the frame height adjustment device 60 'is installed on the installation rod frame 10c, the upper frame stub 11 in the adjustment rod frame 10a is hooked by the raising and lowering member 63' hooked on the hooking portion 62b3 '. It can be stopped.

  (6) In the embodiment and the like, the downward surface of the upper frame stub 11 in the adjustment wedge frame 10a held by the hook portion of the raising and lowering member is the lower surface of the upper frame stub 11, but the downward surface is the upper surface Not only the lower surface of the frame stub 11 but another downward surface existing in the existing heddle frame 10 may be used.

  For example, in a so-called riderless type of heddle frame which is a known heddle frame and a carrier rod for supporting the eaves is directly attached to the lower end portion of the upper frame steel, the eaves supported by the carrier rod are visible Some of the support portions of the carrier rod in the upper frame steel are formed with a plurality of holes passing through the support portions in the lateral direction so as to allow for maintenance and maintenance. Therefore, in the case where the heddle frame has such a hole, it may be hooked to the hooking portion of the elevating member on the inner peripheral surface of the hole, in which case the inner peripheral surface of the hole is The downward facing portion is the above downward surface. In addition, when the heald frame has a downward facing surface that can be latched by the locking portion, the surface may be the above downward surface.

  Incidentally, the height position adjustment operation of the adjustment shed frame 10a using the frame height adjustment device according to the present invention is performed using, for example, two frame height adjustment devices. More specifically, a frame height adjustment device is installed on the upper frame stub 11 of the adjustment rod frame 10a in the vicinity of the side stays 12 on both sides in the lateral direction, and the height of the adjustment rod frame 10a is adjusted by a pair of frames It shall be in a state that can be supported by the device. Then, both of the pair of support members 21 and 21 in the drive transmission mechanism 20 for supporting the adjustment rod frame 10a are made to be capable of changing the entire length as described above, and in that state, the height of the adjustment rod frame 10a A position adjustment operation is performed.

  However, when performing the height position adjustment operation of the adjustment rod frame 10a using the frame height adjustment device according to the present invention, it is not necessary to use two of the frame height adjustment devices as described above, and the frame height adjustment It is also possible to carry out the task using only one device. In that case, with regard to the adjustment rod frame 10a, the adjustment of the height position was first performed as described above only for one side of the both sides in the lateral direction, and the adjustment work of the height position of the one side was completed. After that, the height position adjustment operation may be performed on the other side.

  The present invention is not limited to any of the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
