Description

  The present invention relates to a loom, in particular, a plurality of eaves frames, an opening driving device for vertically driving each eaves frame, and an opening driving device provided for each eave frame and connecting the opening drive device and the eaves frame. A loom height position adjusting device for use in a loom having an opening device including a drive transmission mechanism and a drive transmission mechanism configured to change a support height in the vertical direction of the rib frame. The present invention relates to a saddle frame height position adjusting device for a loom used at the time of adjusting the height position of the saddle frame performed before the start of operation.

  The opening device in the loom as described above is, for example, as shown in FIG. The opening device includes a plurality of drive transmission mechanisms provided corresponding to the respective flange frames, and includes a drive transmission mechanism that connects the corresponding flange frame and a swing lever in the opening drive device. Each of the drive transmission mechanisms is configured to convert the reciprocating swing motion of the swing lever in the opening drive device into the vertical motion of the collar frame. Each drive transmission mechanism includes a pair of rod-shaped support members, and one end of each support member is connected to a corresponding frame so that it is attached to the lower end of the frame. Therefore, each collar frame is in a state of being supported by a pair of support members in the corresponding drive transmission mechanism, and the height position thereof is determined by the length of the support member.

  In the loom, the height position of each frame in the opening device is adjusted in accordance with the weaving of the fabric after the change at the time of adjustment work performed before the start of the operation of the loom due to the change of the weaving fabric. Work (hereinafter, also referred to as “height position adjustment work”) may be performed. And the adjustment of the height position of each rib frame in the loom equipped with the opening device as described above is performed by changing (adjusting) the length of the pair of support members that support the rib frame. This is done by adjusting the position.

  Specifically, each support member in each drive transmission mechanism includes a connecting rod that is connected to the collar frame at one end thereof and a cylindrical support body into which a portion on the other end side of the connecting rod is inserted. And each support member can change the length (overall length) as a whole by changing the insertion amount of the connecting rod with respect to a support body. The position of the connecting rod with respect to the support is fixed with a fixing screw screwed into the support. That is, each support member can be changed in its overall length (insertion amount of the connecting rod with respect to the support) by loosening the fixing screw, and the entire length is determined by tightening the fixing screw. ing. Since each support member supports the eaves frame in the vertical direction as described above, in the opening device, the height position of the eaves frame is adjusted by changing the overall length of the support member. The

  Therefore, when adjusting the height position of the collar frame, loosen the fixing screw to change the overall length of the support member that supports the collar frame to be adjusted, and in that state the height of the collar frame can be changed. After changing the position to a position corresponding to the next weaving, an operation is performed in which the fixing screw is tightened to determine the height position of the heel frame (the entire length of the support member).

  By the way, in the opening device, each collar frame is supported by the support member in the corresponding drive transmission mechanism as described above. In other words, the weight of each collar frame is received by the support member in the corresponding drive transmission mechanism. It is in the state that was. Therefore, when adjusting the height position of the collar frame as described above, if the fixing screw in the support member is loosened without supporting the collar frame in the vertical direction, the collar frame loses its support and falls due to weight. For this reason, the height position adjustment work of the collar frame must be performed while supporting at least the collar frame, and on that, the work of loosening or tightening the fixing screw located below the collar frame must be performed. The work requires two or more workers.

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

  The device disclosed in Patent Document 1 is applied to a different type from the above-described opening device of the present invention. However, in the connecting portion between the rod and the rod frame in the drive transmission mechanism, The mechanism for adjusting the height position of is incorporated.

  In addition, the device disclosed in Patent Document 2 is not incorporated into the opening device as in the device of Patent Document 1, but exists alone as a tool for adjusting the height position of the collar frame, It is installed in the form that it is placed on the fixed part of the loom during the height position adjustment work of the reed frame. And the apparatus of the patent document 2 is provided with the engagement means engaged with the side stay of a cocoon frame, and in the state mounted in the fixing | fixed part of a loom, it is connected with a cocoon frame by the engagement means. The hook frame can be held (the rib frame can be supported), and the height of the rib frame is changed by displacing the engaging means in the vertical direction by the lifting mechanism ( Adjustment).

  However, since the device of Patent Document 1 has a structure in which the mechanism is incorporated for each frame of the opening device, the structure of the opening device is complicated, and the manufacturing cost is increased. It is to be included. In addition, in the case of the configuration, the weight of the portion that moves up and down (including the heel frame) during the opening movement increases, and thus the adoption of the configuration incorporating the mechanism can 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 collar frame only when the height position of the collar frame is adjusted. The problem of concern in the apparatus of 1 does not arise. However, in the case of the device disclosed in Patent Document 2, as described above, the engaging means that engages the collar frame is displaced in the vertical direction to adjust the height position of the collar frame. The configuration for engaging with the collar frame (engagement configuration) causes the following problems.

  First, Patent Document 2 discloses a gripping mechanism (grip device) that grips the side stay in the heel frame in the front-rear direction (the thickness direction of the heel frame) as the engagement configuration. Specifically, the gripping mechanism includes a main body portion, a fastening portion, and a clamp portion, and tightens a male screw included in the fastening portion, so that the side stay is gripped by the main body portion and the clamp portion. It is in an engaged state. However, in the case of such a gripping mechanism that grips the side stay in the front-rear direction, if the gripping force is not strong, the saddle frame is displaced in the vertical direction according to the displacement of the gripping mechanism (engagement means) Therefore, in order to realize the strong gripping force, a considerable amount of force is required for tightening the male screw. Therefore, the apparatus of Patent Document 2 places a heavy burden (labor) on the operator in the work for engaging the engaging means with the frame. Further, when the loom is wide, the weight of the heel frame is large, and therefore, the engagement by gripping as described above may not be able to reliably raise and lower the heel frame in accordance with the displacement of the engaging means.

  Further, in Patent Document 2, as the engagement structure, an engagement pin provided in an engagement means is fitted into an engagement hole formed in a side stay of the flange frame, separately from the gripping mechanism as described above. The structure to be made is also disclosed. However, in the case of the configuration, since such an engagement hole is not formed in a generally used frame, when using the apparatus of Patent Document 2 with the configuration for an existing loom, A new hole must be drilled in the frame. Further, when such a hook frame is formed with such an engagement hole, the number of processing steps increases accordingly, resulting in an increase in manufacturing cost. Furthermore, the hook frame is driven in the vertical direction at high speed during weaving of the loom, but as a result of forming such engagement holes in the side stay, the strength of the hook frame may be reduced.

Japanese Patent Laid-Open No. 11-107103 JP 2009-293154 A

  The present invention has been made in view of the problems of the conventional apparatus as described above. The object of the present invention is provided as an independent tool in the same manner as the apparatus of Patent Document 2 described above. It is an object of the present invention to provide an eaves frame height position adjustment adjustment device that can be engaged with the eaves frame without adding new processing to the frame and can reliably adjust the elevating position of the eaves frame. .

  In order to achieve the above object, the present invention is premised on the above-described rib frame height position adjusting device for a loom, and the rib frame height position adjusting device is mounted on the upper surface of the upper frame Steve in the rib frame. An installation part for placing the support base on the fence frame, and an upper part from the installation part when the support base is placed on the fence frame by the installation part.

  The saddle frame height position adjusting device (hereinafter also referred to as “frame height adjusting device”) according to the present invention is located near (for example, adjacent to) the saddle frame to be adjusted in the installation portion of the support base. The frame (hereinafter referred to as “other frame frame”) is placed on the upper surface of the upper frame steve (hereinafter referred to as “upper frame steve”). In the installed state, the adjustment mechanism supported by the support base is in a state of being positioned above the collar frame in the vertical direction. In addition, the frame height adjusting device is in a state where the adjusting mechanism supports the elevating member at the displacement portion in the installed state. Further, the elevating member latches the downward surface of the upper frame steve (for example, the lower surface of the upper frame steve / hereinafter referred to as “downward surface”) in the hook frame to be adjusted at the latching portion, and the upper frame. Engage with Steve. Accordingly, in this state, the displacement portion of the adjustment mechanism and the adjustment target frame are connected by the elevating member.

Accordingly, the adjustment target frame connected to the displacement portion via the lifting member is displaced (lifted) in the vertical direction.

  As described above, the frame height adjusting device according to the present invention includes the lifting member supported by the support base via the adjustment mechanism in the state where the frame is adjusted on the support base as described above. In the latching portion, the downward surface of the upper frame steve in the collar frame to be adjusted is latched. That is, in this state, the adjustment target frame is supported by the support base installed on the other frame through the lifting member and the adjustment mechanism in the upper frame Steve.

  Therefore, according to the frame height adjusting device of the present invention, when adjusting the height position of the eaves frame, the fixing screw of the support member in the drive transmission mechanism of the opening device is loosened to support the eave frame to be adjusted by the support member. Even if the state is released, the weight of the frame to be adjusted is supported by the frame height adjusting device (elevating member), and the frame height adjusting device (more specifically, through the frame height adjusting device). It is supported by the other frame. Thereby, according to the frame height adjusting device of the present invention, in the height position adjusting work of the heel frame, the fixing screw of the support member is loosened even if the operator does not support the heel frame to be adjusted (綜 絖The frame can be displaced in the vertical direction), and the height position of the eaves frame can be adjusted with a smaller number of people (minimum is one).

  Moreover, according to the frame height adjusting device of the present invention, the connection between the frame height adjusting device and the adjustment target frame, more specifically, the displacement portion displaced in the vertical direction in the adjustment mechanism and the adjustment target frame. Is connected to the latching portion of the elevating member by latching the downward surface existing on the upper frame steve of the adjustment target frame. That is, in the frame height adjusting device of the present invention, the engagement between the elevating member on the frame height adjusting device side and the eaves frame to be adjusted causes the latching portion in the elevating member to be the upper frame Steve in the eave frame to be adjusted. It is performed only by making the downward facing surfaces face each other. In this state, when the support state of the drive transmission mechanism for the adjustment target collar frame is released, the weight of the adjustment target collar frame is applied to the latching portion. The combined state becomes strong. Therefore, according to the frame height adjusting device of the present invention, the operation of connecting the frame height adjusting device and the adjustment target frame can be easily performed without imposing a heavy burden on the operator, and the frame frame. On the other hand, it is possible to ensure the connection between the frame height adjusting device (elevating member) and the frame to be adjusted without adding new processing.

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

  Further, 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). The abutment 51c is formed as described above. In this embodiment, the abutment portion 51c is formed so as to be continuous with the edge on the other end side of the guide portion 51a.

  Further, the support base 51 has an installation portion 51d formed so as to extend in the plate thickness direction at a boundary portion between the guide portion 51a and the insertion portion 51b in the support base 51. However, the extending direction of the installation part 51d with respect to the guide part 51a is the opposite direction to the abutment part 51c with respect to the plate thickness direction. Further, the length of the installation portion 51d in the plate thickness direction is substantially the same as the thickness of the eaves frame 10 (frame steve 11). Furthermore, in the present embodiment, a pair of the installation portions 51d are provided in a form that is continuous with the edge on the guide portion 51a side in each of the protruding portions of the insertion portion 51b. In other words, in this embodiment, the support base 51 has a pair of installation portions 51d and 51d.

  The support base 51 is formed of a single plate material as described above, and the guide portion 51a, the insertion portion 51b, the abutment portion 51c, and the pair of installation portions 51d and 51d are integrally formed.

More specifically, the abutment portion 51c is formed by bending a portion of the plate material on the side opposite to the insertion portion 51b side with respect to the guide portion 51a. Further, the pair of installation portions 51d and 51d are formed by bending portions of the plate material protruding from the edge on the guide portion 51a side of the protruding portion of the insertion portion 51b on both sides of the guide portion 51a in the width direction. Yes.

  Incidentally, when the frame height adjusting device 50 is used, that is, when the height position of the collar frame 10 is adjusted, the frame height adjusting device 50 is provided on the lower surface of the pair of installation portions 51d and 51d in the support base 51. It is installed on the upper surface of the upper frame Steve 11 in the adjacent saddle frame 10b. And in the installation state, the guide part 51a in the support base 51 will be in the state extended toward upper direction from the installation part 51d. In the installed state, the insertion portion 51b in the support base 51 is inserted into the gap between the adjustment rod frame 10a and the adjacent rod frame 10b. Therefore, the plate thickness (thickness dimension) of the insertion portion 51 b, that is, the plate thickness of the plate material forming the guide portion 51 a and the insertion portion 51 c can be inserted into the gap of the frame 10.

  In addition, the guide portion 51a of the support base 51 has a long hole 51a1 for guiding displacement along the extending direction (the longitudinal direction) of the guide portion 51a of the displacement portion 52b of the adjusting mechanism 52 described later. It extends in the direction and penetrates in the plate thickness direction. Further, an insertion hole 51c1 through which the displacement portion 52b is inserted is formed in the abutment portion 51c of the support base 51 so as to penetrate in the longitudinal direction. The abutment portion 51c functions as a position restricting portion for restricting the position of the adjusting mechanism 52 in the width direction and the plate thickness direction.

  The adjustment mechanism 52 includes an adjustment portion 52a that is supported by the support base 51 and has a screw portion, and a displacement portion 52b that is supported by the support base 51 via the adjustment portion 52a by being screwed to the adjustment portion 52a.

Therefore, the screw portion of the adjustment portion (wing nut) 52a is the female screw portion 52a1 of the female screw hole formed in the wing nut 52a.

  Further, in this embodiment, the displacement portion 52b mainly includes a bolt member 52b1 screwed into the female screw portion 52a1 of the wing nut (adjustment portion) 52a and a support block 52b2 attached to the bolt member 52b1. It is an element. The bolt member 52b1 is a screw member in which a male screw is cut over the entire shaft portion extending from the head portion, and the shaft portion is assumed when the height position of the collar frame 10 is adjusted. The frame 10 has a length dimension larger than the adjustment amount (displacement amount) of the frame 10.

  Further, the support block 52b2 is a rectangular parallelepiped block-like member, and constitutes the displacement portion 52b together with the bolt member 52b1 by being attached to the tip of the bolt member 52b1 (the end opposite to the head). 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) coincides with the axial direction of the bolt member 52b1.

  In the present embodiment, the support block 52b2 is an attachment hole 52bx that opens to one of both end faces (two faces excluding the side face), and an internal thread is cut on the inner peripheral face thereof. A hole 52bx is formed. The support block 52b2 is attached to the bolt member 52b1 in such a manner that the bolt member 52b1 is screwed into the attachment hole 52bx in the support block 52b2. Accordingly, the support block 52b2 can be attached to and detached from the bolt member 52b1.

  The support block 52b2 is formed with through holes 52by that open to two of the side surfaces in parallel and pass through the support block 52b2 in parallel with the other side surfaces. In the present embodiment, two through holes 52by are formed apart from each other in the long side direction of the side surface. Further, each through hole 52by is formed as a female screw hole in which a female screw is cut on its inner peripheral surface.

  In addition, a screw member 52b3 is screwed into each through hole (female screw hole) 52by. That is, two screw members 52b3 and 52b3 are attached to the support block 52b2 so as to be screwed into the through holes 52by. However, each of the screw members 52b3 protrudes from the side surface of the support block 52b2 in the attached state. And the structure will be in the state by which the hook part for supporting the raising / lowering member 53 was formed in the displacement part 52b so that it may mention later. In other words, the displacement part 52b including the support block 52b2 has a hook part for supporting the elevating member, and the screw member 52b3 attached to the support block 52b2 functions as the hook part. .

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

  When the adjustment mechanism 52 having such a configuration is assembled to the support base 51, first, the wing nut 52a is screwed into the bolt member 52b1. Then, the bolt member 52b1 in which the wing nut 52a is screwed into the insertion hole 51c1 of the abutment portion 51c in the support base 51 is inserted from the distal end side. Then, the support block 52b2 is attached to the bolt member 52b1 as described above. Thereby, the adjustment mechanism 52 (displacement part 52b) will be in the state assembled | attached to the support base body 51 in the form inserted in the insertion hole 51c1 of the support part 51c in the bolt member 52b1. Incidentally, the insertion hole 51c1 in the support base portion 51c of the support base 51 has a size that allows passage of the shaft portion of the bolt member 52b1 and displacement in 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 faces the plate surface of the guide portion 51a in the support base 51. State. That is, in the assembled state, the openings of the through holes 52by and 52by in the support block 52b2 are opposed to the long holes 51a1 formed in the guide portion 51a in the support base 51.

  In addition, 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 attached to the support block 52b2 by being screwed from the opposite side surface. However, the attachment state of the screw member 52b4 to the support block 52b2 is such that 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 plate thickness of the guide portion 51a in the support base 51. It is supposed to become bigger. In addition, the dimension in the width direction of the long 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 extending direction of the long hole 51a1 in the long hole 51a1. It is allowed to be displaced.

  Due to this configuration, in the assembled state, the displacement of the support block 52b2 (displacement portion 52b) in the extending direction of the long hole 51a1 in the support base 51 (= the longitudinal direction of the guide portion 51a) causes the long hole 51a1 and the screw member 51b4 to be displaced. The support block 52b2 cannot be separated from the guide portion 51a in the support base 51 in the plate thickness direction.

  As described above, in the installed state of the frame height adjusting device 50 during the height position adjusting operation of the collar frame 10, the guide part 51a in the support base 51 is located above the installation part 51d on the adjacent collar frame 10b. It will be in a state extending towards Therefore, in the installed state, the displacement portion 52b of the adjustment mechanism 52 is in a state of being supported by the abutment portion 51c of the support base 51 by 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 portion 51c in the support base 51 while supporting the weight of the displacement portion 52b and the like. Further, when the height position of the collar frame 10 is adjusted, the weight of the adjustment collar frame 10a is also applied to the wing nut 52a via the elevating member 53 as will be described later.

  Thus, during the height position adjustment work of the collar frame 10, the wing nut 52 a as the adjustment portion in the adjustment mechanism 52 is placed on the abutment portion 51 c in the support base 51, and the downward displacement is supported. While being restricted by the pedestal 51c, it is in a state of being pressed against the abutment 51c under the weight of the displacement portion 52b, the collar frame 10, and the like. That is, the wing nut 52a is in a state in which displacement in the vertical direction (the extending direction of the guide portion 51a in the support base 51) is limited.

  In this state, when the wing nut 52a is rotated to change the screwing position of the wing nut 52a and the bolt member 52b1 in the axial direction of the bolt member 52b1, the extending direction of the wing nut 52 ( As the displacement in the vertical direction is limited, the bolt member 52b1 is displaced in the extending direction. That is, in the installation state, the frame height adjusting device 50 rotates the wing nut 52a as the adjusting portion in the adjusting mechanism 52, so that the displacement portion 52b including the bolt member 52b1 is moved to the guide portion 51a in the support base 51. It has a configuration that is displaced in the extending direction.

  In this embodiment, the elevating member 53 is formed of a bar (round bar-shaped member). In addition, the said bar for forming the raising / lowering member 53 is a thing of the outer diameter which can be penetrated in the said gap | interval between the several frame frames 10 with which a loom is equipped.

  Further, the elevating member 53 has a configuration in which an end portion of the bar is bent, and a hooking portion 53a formed at one end thereof and the other end portion (the side opposite to the hooking portion 53a side). And a support portion 53b formed at the end portion. In addition, the latching | locking part 53a is a part for making the frame 10 latched with respect to the raising / lowering member 53. As shown in FIG. Further, the support portion 53 b is a portion for setting the elevating member 53 to be supported by the displacement portion 52 b in the adjustment mechanism 52. And the raising / lowering member 53 becomes the structure by which the latching | locking part 53a and the support part 53b were connected by the rod-shaped base 53c.

  More specifically, the hook 53a is formed by bending a portion on one end side of the bar in the same direction at two locations, and the portion is substantially viewed from the side. It has a U-shape. In addition, in the latching | locking part 53a, the bending angle in the said 2 bending parts is a substantially right angle. Therefore, of the two bent portions, the distal portion of the hook portion 53a is located on the distal end side of the bent portion on the distal end side, and the portion on the base portion 53c side of the bent portion on the base portion 53c side is the base portion. If it is set as a side part, as for the latching | locking part 53a, the front-end | tip part and the base part side will have made the shape substantially parallel. Further, the distance between the tip portion and the base portion, that is, the length of the portion (intermediate portion) between the tip portion and the base portion and extending in a direction substantially orthogonal to the base 53c, It is substantially the same as the thickness of the eaves frame 10 (frame steve 11), and can receive the frame steve 11 of the eaves frame 10 between the tip portion and the base portion.

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

  The elevating member 53 having such a configuration is adjusted to be supported by the support base 51 in the installed state when the frame height adjusting device 50 is used, that is, when the height position of the eaves frame 10 is adjusted. The hook 52b3 of the mechanism 52 (displacement 52b) is hooked at the support 53b. In this state, the elevating member 53 is supported by the displacement portion 52b, and by extension, is 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 latch portion 53a when viewed in the axial direction of the base portion 53c. Therefore, in the state where the elevating member 53 is supported as described above, the intermediate portion of the latching portion 53a is in a state substantially parallel to the plate thickness direction of the support base 51. When the height position of the collar frame 10 is adjusted, the elevating member 53 is oriented so that the intermediate portion of the latching portion 53a is positioned below the support block 52b2 of the adjustment mechanism 52 as described above. It is hung on the hooking portion 52b3.

  Further, during the height position adjustment work of the collar frame 10, the elevating member 53 is supported as described above, and the downward surface of the upper frame Steve 11 of the adjustment collar frame 10a is latched at the latching portion 53a. It is supposed to be in a state that has been made. In this embodiment, the downward surface of the upper frame steve 11 is the lower surface of the upper frame steve 11. Furthermore, the latching state of the lower surface by the latching portion 53a is achieved by receiving the upper frame steve 11 in the latching portion 53a as described above. Accordingly, the elevating member 53 receives the upper frame steve 11 at the latching portion 53a while being 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 steve 11. In other words, the length of the base portion 53c between the support portion 53b and the latching portion 53a is set to be larger than the vertical dimension of the frame steve 11. .

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

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

  Next, as the procedure 2, the elevating member 53 has the base 53c positioned on the side opposite to the side of the adjacent rod frame 10b with respect to the adjustment rod frame 10a, and the upper frame steve of the adjustment rod frame 10a on the hook 53a. 11 is received.

  In this procedure 2, as shown in FIG. 2, there is also a collar frame 10 on the opposite side of the adjacent collar frame 10b with respect to the adjustment collar frame 10a in the front-rear direction, and the upper frame of the collar frame 10 on the opposite side. When the steve 11 is present at a position facing the upper frame steve 11 in the adjustment rod frame 10a, the procedure 2 goes up and down in 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 latching portion 53a side with the intermediate portion of the latching portion 53a facing the lateral direction of the collar frame 10. . Next, with the latching portion 53a positioned below the upper frame steve 11 of the adjustment rod frame 10, the elevating member 53 is rotated around the axis of the base 53c, and the intermediate portion is the upper frame steve of the adjustment rod frame 10a. 11 is opposed to the lower surface. In this state, the lowering member 53 is lifted to raise the lower portion of the upper frame steve 11 to the latching portion 53a.

  Then, as step 3, the lifting member 53 that has received the upper frame steve 11 of the adjusting rod frame 10a in the engaging portion 53a as described above, the support portion 53b is a hooking portion in the adjusting mechanism 52 (displacement portion 52b). 52b3 is supported by the adjusting mechanism 52. When performing this procedure 3, the vertical position (height position) of the hook 52b3 (support block 52b2) in the adjustment mechanism 52 is set so that the upper frame Steve 11 of the adjustment rod frame 10 is hooked as described above. Adjustment is made so that the height position of the support portion 53b and the height position of the hooking portion 52b3 in the elevating member 53 in the state of being received by 53a match.

  Incidentally, in the frame height adjusting device 50 of the present embodiment, the adjusting mechanism 52 (displacement portion 52b) has two hooking portions 52b3 attached to the support block 52b2 so as to be spaced apart in the vertical direction in the installation state. , 52b3. This can be selectively used depending on the vertical dimension of the upper frame Steve 11 in the adjustment rod frame 10a. Therefore, two hooking parts 52b3 are not necessarily required, and only one hooking part 52b3 may be provided. The hook 52b3 is not limited to the screw member as described above, but is configured of a pin or the like provided so as to be inserted into a hole formed in the support block 52b. 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, by the procedure 3 as described above, the upper frame steve 11 in the adjustment rod frame 10 a and the adjustment mechanism 52 in the frame height adjustment device 50 are connected by the elevating member 53. Therefore, by performing the above steps 1 to 3, the frame height adjusting device 50 is in a state where the height position of the adjusting rod frame 10a can be adjusted.

  In addition, when adjusting the height position of the adjusting rod frame 10a, the support member 21 in the drive transmission mechanism 20 that supports the adjusting rod frame 10a can change the overall length as described above. In other words, the fixing screw 21c that fixes the position of the connecting rod 21a with respect to the support 21b is loosened. Accordingly, 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 hook portion 53a of the elevating member 53 in the frame height adjusting device 50 in the upper frame Steve 11, and the intermediate portion of the hook portion 53a in the vertical direction. The portion is in contact with the lower surface of the upper frame Steve 11. Thereby, even if the support by the support member 21 is lost, the latching portion 53a (the intermediate portion) is in a state of latching the lower surface of the upper frame steve 11. Therefore, the adjustment rod frame 10a is supported via the frame height adjustment device 50 with respect to the adjacent rod frame 10b on which the frame height adjustment device 50 is installed, in other words, supported by the frame height adjustment device 50. It becomes a state.

  Next, in this state, when the wing nut 52a as the adjustment portion in the adjustment mechanism 52 is rotated, the displacement portion 52b is displaced in the vertical direction (the extending direction of the guide portion 51a), and the displacement portion 52b The height position of the adjustment rod frame 10a connected by the elevating member 53 is changed. When the adjustment rod frame 10a reaches a desired height position, the fixing screw 21c of the support member 21 in the drive transmission mechanism 20 is tightened, so that the height position is determined. Incidentally, the height position of the adjustment rod frame 10 is set with reference to the upper surface of the rod frame guide 40, for example, and from the reference to the upper surface of the upper frame Steve 11 by a scale or the like while changing the height position as described above. It is adjusted while measuring the distance.

  In the above, one embodiment (example) of the present invention has been described. However, the frame height position adjusting device of the present invention is not limited to that described in the above embodiment, and the following embodiment is provided. Implementation in (Modification) is also possible.

  (1) In the above-described embodiment, the adjustment mechanism is configured by the combination of the wing nut 52a as the adjustment portion, the bolt member 52b1, and the support block 52b2. However, the heel frame height position adjustment device according to the present invention. The adjusting mechanism is not limited to such a configuration, and may be, for example, a configuration as shown in FIG. 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 adjusting 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 above embodiment, and the guide portion 61a and the insertion portion 61b. In the boundary portion (one end side in the longitudinal direction of the guide portion 61a), there is an installation portion 61d formed so as to extend in the plate thickness direction of the guide portion 61a. In addition, the guide portion 61a is formed with a long hole 61a1 extending in the extending direction of the guide portion 61a (the longitudinal direction), like the support base 51 of the embodiment.

  Furthermore, 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 plate thickness direction, the direction in which the receiving portion 61c extends is opposite to the abutment portion 51c of the support base 51 in the embodiment, and the receiving portion 61c is the same as the installation portion 61d with respect to the guide portion 61a. The direction is located on the side. Further, the receiving portion 61c is formed with an insertion hole 61c1 through which a feed screw 62a in an adjusting mechanism 62 described later can be inserted. 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 abutment portion 51c in the support base 51 of the embodiment.

  Further, in the frame height adjusting device 60, the support base 61 has a rear wall portion 61e extending in parallel with the insertion portion 61b from the end portion on the opposite side to the guide portion 61a side of the installation portion 61d in the plate thickness direction. Have. That is, the support base 61 has a substantially U-shaped portion (U-shaped portion) including the installation portion 61d on the other end side of the guide portion 61a. And in the installation state with respect to the adjacent saddle frame 10b, the frame height adjusting device 60 is installed in the installation portion 61d in a state where the upper part of the upper frame Steve 11 in the adjacent saddle frame 10b is received inside the U-shaped portion. It is in a state of being placed on the upper frame Steve 11 of the frame 10. Further, in the support base 61, the installation portion 61d is formed not only on both sides of the insertion portion 61b in the width direction but also in the center of the insertion portion 61b, unlike the support base 51 of the embodiment. Accordingly, the support base 61 has a configuration in which a central installation portion 61d (hereinafter, referred to as “central installation portion 61d1” to be distinguished from the installation portions 61d on both sides) faces the receiving portion 61c in the longitudinal direction. It has become.

  The adjusting mechanism 62 is configured by the feed screw mechanism as described above, and includes the feed screw 62a and the nut member 62b. The feed screw 62a is inserted into the frame height adjusting device 60 in a state where the axis thereof is parallel to the longitudinal direction (the extending direction) and is inserted into the insertion hole 61c1 in the receiving portion 61c of the support base 61. Incorporated. As described above, the receiving portion 61c and the central installation portion 61d1 in the support base 61 are opposed to each other in the longitudinal direction. As a result, the lead screw 62a is in a state where the tip of the lead screw 62a can come into contact with the central installation portion 61d1 in the state of being inserted into the insertion hole 61c1 as described above. In the installation 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 obtained by integrally combining two rectangular parallelepiped block-shaped members, and a rectangular parallelepiped screwed portion 62b1 which is a portion screwed to the feed screw 62a, and an elevating / lowering portion. It is comprised with the rectangular parallelepiped shaped base part 62b2 to which the hook parts 63b3 and 63b3 to which the member 63 is hung are attached. In the frame height adjusting device 60 of this example, the lifting member 63 has the same configuration as the lifting member 53 in the frame height adjusting device 50 of the above embodiment. The hooking portions 62b3 and 62b3 are the same as the hooking portion (screw member) 53b3 in the above-described embodiment, and the state of attachment to the nut member 62b (mounting portion 62b2) is also the hooking portion with respect to the support block 52b in the above-described embodiment. It is assumed that it is the same as the attachment state of 53b3.

  Further, with respect to the nut member 62b, the screwing portion 62b1 is a female screw hole penetrating in the long side direction in parallel with the side surfaces (four surfaces having the same long side length), and is screwed with the feed screw 62a. A mating 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. The gantry 62b2 is formed integrally 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, the threaded portion 62b1 has a shorter side dimension of the side surface (projecting side surface) from which the gantry 62b2 projects than the width dimension of the long hole 61a1 formed in the guide portion 61a of the support base 61. Has also been formed greatly. The gantry 62b2 has a short side dimension parallel to the protruding side surface of the threaded part 62b1 that is substantially the same as the width dimension of the long hole 61a1 of the guide part 61a, and can be inserted into the long hole 61a1. In addition, it is slidable in the extending direction of the long hole 61a1.

  In addition, in the frame height adjusting device 60, the nut member 62b is screwed at the screwing portion 62b1 with the feed screw 62a inserted through the insertion hole 61c1 of the receiving portion 61c as described above. The protruding side surface of the screwing portion 62b1 faces the guide portion 61a, and the gantry portion 62b2 is inserted into the long hole 61a1 of the guide portion 61a.

  However, the dimension (projection dimension) in the projecting direction of the gantry part 62b2 from the screwing part 62b1 is larger than the plate thickness of the guide part 61a. Therefore, the gantry 62b2 is in a state of protruding from the guide 61a to the side opposite to the screwing portion 62b1 in the state of being inserted into the long hole 61a1 of the guide 61a as described above. Further, the projecting dimension of the gantry 62b2 is set so that the projecting amount from the guide 61a is substantially the same as the thickness of the collar frame 10 (frame steve 11). In other words, the protruding dimension of the gantry 62b2 is substantially the same as the size of the plate thickness of the guide 61a plus the thickness of the collar frame 10 (frame Steve 11).

  During the height position adjustment work of the collar frame 10, the frame height adjusting device 60 is installed on the hook 62b3 attached to the nut member 62b in the adjustment mechanism 62 while being installed on the adjacent collar frame 10b. On the other hand, the elevating member 63 is hung in the same manner as in the above embodiment, and the elevating member 63 connects the adjusting rod frame 10a and the nut member 62b to support the adjusting rod frame 10a. The In such a state where the adjustment rod frame 10a is supported, the weight of the adjustment rod frame 10 or the like is applied to the feed screw 62a via the elevating member 63 and the nut member 62b, and the feed screw 62a is the above-described central installation portion. It will be in the state pressed against 61d1. Accordingly, in this state, the feed screw 62a is in a state where displacement in the vertical direction (extending direction of the guide portion 61a) is restricted. Further, the nut member 62b is in a state in which rotation is prevented because the gantry 62b2 is inserted into the elongated hole 61a1 in the guide 61a.

  Therefore, by rotating the feed screw 62a in this state, the screwing position of the feed screw 62a and the nut member 62b is changed, and accordingly, the nut member 62b is displaced in the extending direction (vertical direction). Thereby, the adjustment rod 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 vertical displacement of the nut member 62b is guided by the gantry 62b2 sliding in the elongated hole 61a1 in the guide 61a.

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

  (2) In the example described above, the support base in the frame height adjusting device is formed of a single plate material, but the support base is not limited to such a configuration, It may be formed by combining plate materials.

  For example, in the configuration of the above example, another plate material functioning as the installation portions 51d, 61d, the abutment portion 51c, and the receiving portion 61c is bonded to the plate material constituting the guide portions 51a, 61a by welding or the like. There may be. In this case, the abutment portion and the receiving portion 61c do not have to be positioned at the end portion on the other end side of the guide portions 51a and 61a, and the other of the plate materials constituting the guide portions 51a and 61a. The abutment part 51c and the receiving part 61c may be located closer to the installation parts 51d and 61d than the end part on the end side (FIG. 5).

  Further, like 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 to be configured. In the support base 71, unlike the support base 51 of the above-described embodiment, the installation portion 71d is configured to exist within the range where the guide portion 71a exists in the width direction.

  (3) In the above-described embodiments and the like, the elevating member in the frame height adjusting device is formed of a round bar-like member, but the elevating member is not limited to such a configuration, for example, It may be formed of a plate material as shown in FIG. In addition, in the elevating 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. Moreover, the part shown with the code | symbol 73c respond | corresponds to the base 53c in the raising / lowering member 53 of the said Example.

  In addition, about the latching | locking part in a raising / lowering member, in the said Example, the latching part is formed so that it may comprise a substantially U shape. 6 may be used as long as it can be hooked on the downwardly facing surface, and may be formed in a substantially L shape as shown in FIG. Further, the support portion in the elevating member is not limited to the hook shape as shown in the above-described embodiment and FIG. For example, when the elevating member is formed of a plate material as shown in FIG. 6, a hole penetrating in the plate thickness direction is formed, a portion including the hole is used as a support portion, and a hooking portion in the adjusting mechanism is inserted into the hole. In this manner, the lifting member may be supported by the adjustment mechanism.

  Incidentally, when the elevating member is formed of a plate material as described above, the elevating member to the gap between the upper frame steve 11 of the adjusting rod frame 10a and the upper frame steve 11 of the adjacent rod frame 10b. Needs to be inserted from below the upper frame Steve 11. Therefore, in terms of ease of use, the elevating member formed of a round bar-like member that can be inserted into the gap from above the upper frame steve 11 is more advantageous as in the above-described embodiment.

  (4) In the embodiment and the example shown in FIG. 4, the support bases 51 and 61 are portions extending from the installation portions 51d and 61d to the opposite side of the guide portions 51a and 61a in the longitudinal direction (insertion portions 51b). 61b and rear wall portion 61e), the frame height adjusting device according to the present invention is installed in such a manner that it is placed on the upper frame steve 11 of the eave frame 10 at the installation portion of the support base. Since it is only necessary to be able to be performed, the part can be omitted. That is, the support base may not have the insertion portions 51b and 61b and the rear wall portion 61e as in the above-described embodiment and the example shown in FIG.

  However, since the installation position of the frame height adjusting device and the position of the adjustment rod frame 10a are misaligned with respect to the front-rear direction, it is installed on the adjacent rod frame 10b during the height position adjustment work of the adjustment rod frame 10a. When the adjusted frame height adjusting device is in a state of supporting the adjusting rod frame 10a, the force to try to tilt the frame height adjusting device toward the adjusting rod frame 10a due to the weight of the adjusting rod frame 10a or the like. Acts on the adjusting device. Therefore, in order to cope with such a force acting, it is preferable that the support base has a configuration having at least an insertion portion in the above-described embodiment.

  (5) In the above-described embodiment and the like, when adjusting the height position of the adjustment rod frame 10a, the installation position of the frame height adjustment device is set to the frame frame 10 adjacent to the adjustment rod frame 10 in the front-rear direction (adjacent frame frame). 10b), the installation position of the frame height adjusting device is not limited to such an adjacent saddle frame 10b, but may be on another saddle 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 embodiment, that is, the hooking portion 53a in the front-rear direction. Is in a state in which the elevating member 53 is hooked on the hooking portion 53b3 in such a direction as to be located on the opposite side of the support base 51 from the guide portion 51a with respect to the support block 52b2, thereby In the state where the frame height adjusting device 50 is installed on the rod frame 10 (hereinafter referred to as “installation rod frame 10c”) located on the side opposite to the adjustment rod frame 10a in the front-rear direction, The upper frame steve 11 can be hooked on the hook 53a of the elevating member 53.

  Further, as shown in FIG. 7B, for example, the frame height adjusting device is configured so that the hooking portion in the adjusting mechanism is farther away from the guide portion in the supporting base than in the configuration of the embodiment or the like in the front-rear direction. The frame height adjusting device may be used by being installed on the other frame 10.

  The example shown in FIG. 7B is a modification of the frame height adjusting device 60 shown in FIG. 4, and in the frame height adjusting device 60 ′, the nut member 62b ′ has its pedestal portion 62b2. The protrusion dimension of 'is larger than the configuration shown in FIG. 4 (specifically, twice the configuration shown in FIG. 4). In the case of the configuration, when the frame height adjusting device 60 ′ is installed on the installation rod frame 10c as described above, the side surface to which the hook portion 62b3 ′ of the gantry 62b2 ′ of the nut member 62b ′ is attached is With respect to the direction, the adjustment rod frame 10a is located at substantially the same position as the surface of the upper frame Steve 11 on the side opposite to the adjacent rod frame 10b side. Therefore, the configuration is such that the upper frame steve 11 in the adjustment rod frame 10a is hung by the elevating member 63 ′ hung on the hook 62b3 ′ with the frame height adjustment device 60 ′ installed on the installation rod frame 10c. It can be stopped.

  (6) In the above-described embodiment and the like, the downward surface of the upper frame steve 11 in the adjustment rod frame 10a latched by the latching portion of the elevating member is used as the lower surface of the upper frame steve 11. Not only the lower surface of the frame steve 11 but other downward surfaces existing in the existing frame 10 may be used.

  For example, in a so-called riderless type frame where a carrier rod that supports the rod is directly attached to the lower end portion of the upper frame Steve, the rod supported by the carrier rod is visually recognized. In order to perform maintenance and maintenance, there is a carrier rod support portion in the upper frame Steve in which a plurality of holes penetrating the support portion are formed in the lateral direction. Therefore, when the eaves frame has such a hole, it may be hooked to the latching portion of the elevating member at the inner peripheral surface of the hole, and in that case, the inner peripheral surface of the hole The portion facing downward is the downward surface. In addition, when the hook frame has a downward-facing surface that can be latched by the locking portion, the surface may be the downward surface.

  Incidentally, the height position adjusting work of the adjusting rod frame 10a using the frame height adjusting device according to the present invention is performed using, for example, two frame height adjusting devices. Specifically, a frame height adjusting device is installed on the upper frame Steve 11 of the adjustment rod frame 10a in each of the vicinity of the side stays 12 on both sides in the lateral direction, and the adjustment rod frame 10a is adjusted to a pair of frame heights. It is in a state where it can be supported by the device. In addition, both of the pair of support members 21 and 21 in the drive transmission mechanism 20 that supports the adjustment rod frame 10a can be changed in overall length as described above, and in this state, the height of the adjustment rod frame 10a is set. Work to adjust the position is performed.

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

  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.
