Technical Field

The present invention relates to a frame structure of a loom, the frame structure including one frame and one or more pairs of height position setting members, the frame being configured by connecting a pair of side frames to which beam holders for supporting warp beams are fixed, respectively, by a plurality of beam members, the pair of height position setting members being disposed between a mounting surface of the loom and each of the side frames, and each of the height position setting members being fixed to the mounting surface and the corresponding side frame.

Background

In a general loom, a frame is configured as a main body, and a pair of side frames in a box shape are coupled by a plurality of beam members. A beam holder for supporting the warp beam is attached to each side frame of the frame. The loom further includes a beating-up device including a swing arm shaft that is rotatably driven and a reed supported by the swing arm shaft, and the swing arm shaft is supported by a pair of side frames of the frame.

In such a loom, it is known that each side frame supporting the rocker shaft generates a violent vibration (so-called beating-up vibration) in association with the beating-up operation performed by the beating-up device during weaving. Therefore, each side frame of the frame is firmly fixed to the installation surface of the loom using anchor bolts as in the loom disclosed in patent document 1, for example.

As disclosed in patent document 2, for example, a known loom includes a frame structure including a frame as described above and a lifting member (height position setting member) interposed between a floor (installation surface of the loom) and the frame. This is because the use of such a height position setting member makes it possible to cope with a plurality of warp beams having different diameters, while making the structure of the side frame itself the same for each loom. In the frame structure using such a height position setting member, the height position setting member is fixed to the installation surface by anchor bolts and is fixed to the lower surface of the side frame by fixing bolts.

However, in the frame structure of the loom disclosed in patent document 2, there is a problem that the quality of woven fabric is lowered by vibration of the side frame. The details are as described below.

As described above, in the frame structure of the loom disclosed in patent document 2, the side frame is fixed to the height position setting member in a state where the side frame corresponding to the height position setting member is placed on the height position setting member fixed to the installation surface. Therefore, as described above, the fixing of the side frame to the height position setting member using the fixing bolt is performed by fastening with the fixing bolt whose axial direction is directed in the vertical direction. In such a frame structure, the fixation of the position of the side frame with respect to the height position setting member in the horizontal direction is maintained only by the frictional force between the height position setting member (upper surface) and the side frame (lower surface) corresponding to the weight of the side frame and the fastening force of the fixing bolt.

Therefore, such a frame structure is slightly weak against vibration in the horizontal direction in terms of vibration resistance. The beating-up vibration also causes vibration in a horizontal direction including a front-back direction (warp direction) and a width direction (weaving width direction) with respect to the frame (side frame). Therefore, in the frame structure as described above, the side frame may be strongly vibrated in the warp direction and the knitting width direction in accordance with the occurrence of the beating-up vibration. In particular, in recent years, the operation of the loom tends to be faster, and the vibration of the side frame becomes more severe with the higher speed of the loom.

Further, if the side frame vibrates violently in this way, the devices supported by the side frame including the beating-up device vibrate, and there is a problem that the quality of the woven fabric is lowered due to an adverse effect on the weaving. Further, as in the loom disclosed in patent document 1, the case where the frame is directly fixed to the installation surface is more excellent in vibration resistance. However, in this case, it is necessary to manufacture a plurality of types of side frames having different structures so as to correspond to a plurality of types of warp beams having different diameters, and the manufacturing cost of the loom increases.

Disclosure of Invention

Problems to be solved by the invention

In view of the above conventional frame structure of a loom, an object of the present invention is to provide a frame structure of a loom capable of improving vibration resistance against the beating-up vibration in a loom having a frame structure including the height position setting member as described above.

Means for solving the problems

The present invention assumes the following frame structure of a loom: the frame structure of the loom includes one frame and one or more pairs of height position setting members, the frame is formed by connecting a pair of side frames to which beam holders for supporting warp beams are fixed by a plurality of beam members, the pair of height position setting members are arranged between the installation surface of the loom and each side frame, and each height position setting member is fixed to the installation surface of the loom and the corresponding side frame.

In order to achieve the above object, the present invention provides a frame structure of a loom as a premise, wherein the pair of height position setting members are provided as a support structure, and the support structure is configured to be fixed to the corresponding side frame at a position on at least one of the delivery side and the take-up side, the position being an inner side surface or an outer side surface of the side frame.

In the frame structure of the loom of the present invention, the support structure may be a pair of height position setting members disposed on the delivery side of the side frames.

In the frame structure, the beam holder may be integrally formed with the support structure. In the frame structure, the support structure may be fixed to the side frames at positions on inner side surfaces of the side frames.

The effects of the invention are as follows.

According to the present invention, in the frame structure of the loom including the pair of height position setting members, the vibration resistance of the frame structure is improved by providing the support structure in which the pair of height position setting members are fixed to the side surfaces of the side frames on the delivery side and/or the winding side. As described in more detail below.

According to the frame structure of the loom of the present invention, since each height position setting member is fixed to the side surface of the corresponding side frame, the fastening direction of the fixing bolt used for the fixing (the axial direction of the fixing bolt in the fastened state) is parallel to the knitting width direction. In this frame structure, since the side frame is in a state of being received by the height position setting member at the side surface thereof, the vibration in the knitting width direction generated in the side frame by the beating-up vibration is received by the height position setting member directly fixed to the installation surface. Further, although the frictional force generated between each height position setting member and the corresponding side frame in the vertical direction substantially corresponds to the fastening of the fixing bolt, the weight of the side frame is received at the fixing portion, and therefore the vibration resistance in the vertical direction is also the same as that of the conventional frame structure.

Therefore, the vibration resistance of the entire frame structure is improved as compared with the conventional frame structure. Thus, according to the loom using the frame structure, the quality of the woven fabric caused by the beating-up vibration during weaving can be prevented from being degraded, even though the structure of the side frame itself is made the same for each loom.

In the frame structure of the loom according to the present invention, the vibration resistance of the frame structure against beating-up vibration is improved and the vibration resistance against vibration generated by the warp beam is also improved by configuring the frame structure such that the support structure is the height position setting member arranged on the delivery side of the side frame. As described in more detail below.

In a loom, it is known that a tension fluctuation of warp yarns occurs due to shedding motion and beating-up motion in one weaving cycle, and the tension fluctuation becomes an exciting force, and vibration (so-called beam vibration) may occur in a warp beam in a rotation direction and a warp yarn leading-out direction (up-down direction). Therefore, in addition to the beating-up vibration via the rocker shaft, the beam vibration via the beam holder acts on the side frame as an exciting force, and the exciting force generated by the beam vibration acts on the delivery side of the side frame. In a loom in which a warp beam is fitted and inserted into tubular portions at both ends of a bearing supported by a beam holder, an exciting force generated by the vibration of the beam is applied from the bearing to a side frame via the beam holder.

In contrast, in the above-described frame structure of the present invention, the support structure is configured so as to be the height position setting member on the delivery side, and the side frame is in a state of being received by the height position setting member on the side surface of the delivery side portion, which is a portion receiving the exciting force generated by the vibration of the loom beam. Therefore, according to this configuration, the frame structure can also improve vibration resistance against the beam vibration.

In the frame structure in which the support structure is configured as the height position setting member disposed on the delivery side of the side frame as described above, the beam holder configured to support the warp beam is integrally formed in the support structure, thereby further improving the vibration resistance of the frame structure against the vibration of the beam. In detail, in the frame structure in which the support structure is configured as the height position setting member arranged on the delivery side of the side frame as described above, the beam holder is configured to be integrally formed in the support structure, whereby the beam holder is configured to be supported by the support structure. Thus, the frame structure is configured such that the exciting force generated by the beam vibration does not directly act on the side frames. Therefore, according to this configuration, the frame structure further improves the vibration resistance against the beam vibration.

In the frame structure of the loom according to the present invention, the fixing position of the support structure to the side frame is set to the position of the inner side surface of the side frame, whereby the vibration resistance against beating-up vibration can be more effectively improved. In particular, in a typical loom, the position at which the rocker shaft is supported by the side frame in the beating-up device that generates beating-up vibration as described above is on the side of the inner side surface of the side frame. Therefore, the frame structure is configured such that the fixing position of the support structure to the side frame is the inner side surface of the side frame, and the support position of the support structure is the side on which the exciting force by the beating-up vibration is received, so that the vibration resistance against the beating-up vibration can be more effectively improved.

Detailed Description

An embodiment (this example) of a frame structure of a loom to which the present invention is applied will be described below with reference to fig. 1 to 3.

In a loom, a frame 1 is configured such that a pair of side frames 2, 2 are formed as a main body and the side frames 2, 2 are coupled by a plurality of beam members 3. Each side frame 2 is formed in a box shape having a space therein, and the side frames 2 and 2 are coupled by a beam member 3 in a state of facing each other in the width direction (thickness direction).

In addition, the loom is provided with a warp beam 6 for feeding out warp yarns T so as to be supported by the side frames 2, 2 in one of the front-rear direction (the direction orthogonal to the longitudinal direction of the beam member 3 in a plan view). A winding beam 8 for winding the woven cloth is provided on the other side in the front-rear direction of the loom so as to be supported by the side frames 2.

The loom is also provided with a beating-up mechanism for swinging the drive reed 5. In this beating-up mechanism, the reed 5 is supported by the rocker shaft 4 via a plurality of saddle legs and the like. Further, the rocker shaft 4 in this beating-up mechanism is supported by the pair of side frames 2, 2 at both end portions thereof in a direction parallel to the beam member 3.

In the frame structure of a loom including the frame 1 described above, the present invention is premised on the following structure: the frame structure includes a pair of height position setting members disposed between the installation surface of the loom and the side frame on at least one of the delivery side (the side on which the warp beam 6 is installed) and the take-up side (the side on which the take-up beam 8 is installed). In the present embodiment, the frame structure is configured to include a height position setting member on both the feeding side and the winding side.

In addition, in the frame structure of the present invention, the height position setting member on at least one of the delivery side and the winding side is a support structure fixed to the side surface of the corresponding side frame 2, and this embodiment is an example in which the height position setting member on the delivery side is the support structure. Details of the frame construction of such a loom of the present embodiment are as described below.

First, the height position setting members 11 on the winding side are provided in a pair so as to correspond to the side frames 2 and 2, respectively. Each of the height position setting members 11 is a member having a rectangular parallelepiped shape in an overview, and is formed in a size such that a dimension (width dimension) in a short side direction of upper and lower surfaces of the rectangular shape substantially coincides with a dimension in the width direction of the side frame. The height position setting members 11 are formed in the following shapes: the side surfaces on both sides in the short side direction are open, and a wall is formed at substantially the center in the short side direction inside. In addition, each of the height position setting members 11 is provided so as to be interposed between the lower surface of the corresponding side frame 2 and the installation surface 10.

In each height position setting member 11 on the winding side, a plurality of through holes are formed, and the through holes are respectively passed through a lower wall (lower wall) abutting on the installation surface 10 and an upper wall (upper wall) abutting on the lower surface of the side frame 2, and bolts for fixing are inserted therethrough. Each height position setting member 11 is fixed to the installation surface 10 by inserting an anchor bolt protruding from the installation surface 10 into a through hole of the lower wall and screwing a nut to the anchor bolt. Each height position setting member 11 is fixed to the corresponding side frame 2 by inserting a fixing bolt inserted into a through hole formed in the lower surface of the side frame 2 into a through hole in the upper wall and screwing a nut to the fixing bolt.

On the other hand, as described above, the height position setting means on the delivery side serves as the support structure described in the present invention. In addition, a general loom includes a pair of beam holders for supporting the warp beam as described above, and each beam holder is attached to the side frame. In the present embodiment, the beam holder is formed integrally with the support structure. That is, the support structure of the present embodiment includes the beam holder, and is configured by a portion (height position setting portion) functioning as the height position setting member and a portion (beam holder) functioning as the beam holder. Such a support structure will be described in detail below.

The beam holding portion 7 itself has the same form as the conventional beam holder, and includes: a support portion 7a having an arc-shaped support surface for receiving the bearings 6a fitted into the tubular portions (not shown) inserted into the ends of the beam; and a guide portion 7b, an upper surface of which is continuous with the support surface and extends from the support portion 7a, in order to guide the warp beam toward the support portion 7 a. Further, the support portion 7a is formed integrally with the guide portion 7 b.

The beam holding portion 7 has a clamp shank 7c for holding the warp beam 6 received by the support portion 7 a. The clamp handle 7c is rotatably attached to the support portion 7a and is provided to be rotatable between a clamp position to hold the warp beam 6 and a release position to release the warp beam 6. The clamp lever 7c has an arcuate surface 7d which abuts against the outer peripheral surface of the bearing 6a in the beam 6 received by the support portion 7a in the clamped position.

The beam holding portion 7 includes a fixing means 7f for fixing the clamp lever 7c to the guide portion 7b (in a non-rotatable state) in a state where the clamp lever 7c is at the clamp position. In the warp beam holding portion 7, the clamping lever 7c is fixed to the guide portion 7b by the fixing means 7f in a state where the warp beam 6 (the bearing 6a) is received by the support surface of the support portion 7a, and the warp beam 6 is held by the warp beam holding portion 7.

The height position setting unit 14 is constituted by a base portion 14b formed in a plate shape and serving as a base of the support structure 12, and an attachment portion 14a formed on the upper surface side of the base portion 14 b. The base portion 14b is formed in a substantially rectangular parallelepiped shape when viewed in the plate thickness direction, and the dimension of the end surface (upper and lower surfaces) in the short side direction thereof is substantially equal to the dimension of the side frame in the width direction.

The mounting portion 14a is formed in a substantially rectangular parallelepiped shape in appearance, and has a rectangular upper and lower surface. However, the mounting portion 14a has a box shape, and has a shape in which one side surface (side wall) in the short side direction is open. The attachment portion 14a is formed integrally with the base portion 14b in a direction in which the short-side direction (longitudinal direction) of the upper and lower surfaces thereof coincides with the short-side direction (longitudinal direction) of the upper surface of the base portion 14 b. Therefore, a lower wall (lower wall) including the lower surface of the mounting portion 14a becomes a part of the base portion 14 b. In the illustrated example, a rib is formed inside the mounting portion 14a at substantially the center in the longitudinal direction so as to connect the lower surface (base portion 14b) and the upper surface.

The dimension in the short-side direction of the lower surface of the attachment portion 14a substantially coincides with the dimension in the short-side direction of the upper surface of the base portion 14b, and the dimension in the short-side direction of the upper surface thereof substantially coincides with the width dimension of the support portion 7a in the shaft holding portion 7. The dimension in the longitudinal direction of the lower surface of the attachment portion 14a is slightly smaller than the dimension in the longitudinal direction of the upper surface of the base portion 14 b. Therefore, the height position setting unit 14 is formed such that the base portion 14b protrudes in the longitudinal direction from the attachment portion 14a in a plan view. The height direction dimension (height dimension) of the mounting portion 14a is larger than the height dimension of the winding-side height position setting member 11.

In addition, in the support structure 12, the height position setting portion 14 is integrated with the beam holding portion 7 so that the beam holding portion 7 is positioned above the mounting portion 14a of the height position setting portion 14. More specifically, in the support structure 12, the width direction of the beam holding portion 7 is aligned with the short side direction of the height position setting portion 14, and the height position setting portion 14 and the beam holding portion 7 are integrally formed so that the support portion 7a of the beam holding portion 7 is continuous above the attachment portion 14a of the height position setting portion 14.

The pair of support structures 12, which are the pair of height position setting members on the delivery side, are attached to the corresponding side frames 2 on the delivery side. Specifically, each of the support structures 12 is provided inside the corresponding side frame 2 at a position that is a desired position when the warp beam 6 is supported by the beam holding portion 7 in the front-rear direction, so that the side surface of the attachment portion 14a of the height position setting portion 14 is in contact with the side frame 2. In addition, each support structure 12 is fixed to the installation surface and the corresponding side frame 2.

In the fixation of each support structure 12, a plurality of through holes through which bolts for fixation are inserted are formed in the height position setting portion 14, and the through holes are through holes that pass through the side wall including the side surface of the attachment portion 14a and the base portion 14b in the plate thickness direction. In the above arrangement, the support structures 12 are fixed to the side frames 2 by inserting fixing bolts inserted into the through holes of the mounting portions 14a into through holes formed in the inner side surfaces 9 (side walls) of the corresponding side frames 2 and screwing nuts to the fixing bolts. In addition, the anchor bolts protruding from the installation surface 10 are inserted into the through holes of the base portion 14b, and nuts are screwed into the anchor bolts, whereby the support structures 12 are fixed to the installation surface 10.

The support structure 12 integrally includes the beam retainer as the beam retainer 7 as described above, and the beam retainer 7 and the height position setting unit 14 in the support structure 12 are located at the same position in the width direction. Therefore, as a result of fixing the support structures 12 as described above, the position of the bearing 6a of the beam 6 in the width direction becomes the inner side of the support structure 12 supporting the bearing 6a with respect to the corresponding side frame 2. That is, the position of the bearing 6a in the width direction is the same side as the fixing position to the corresponding side frame 2 in the support structure 12 that supports the bearing 6 a.

As described above, in the frame structure of the present embodiment, the support structure 12 including the height position setting unit 14 corresponding to the delivery-side height position setting member is fixed to the corresponding side frame 2 such that the side surface thereof abuts against the inner surface 9 of the corresponding side frame 2. The fixing is performed using a fixing bolt so that the fastening direction is parallel to the width direction of the side frame. Accordingly, the vibration in the width direction generated in the side frame 2 by the beating-up vibration is received by the support structure 12 fixed to the installation surface 10, and the frame structure has improved vibration resistance as compared with the conventional frame structure.

As described above, the fixing position of the support structure 12 to the corresponding side frame 2 is the side of the side frame 2 that supports the rocker shaft 4, i.e., the side of the inner surface 9. That is, the side frame 2 is supported by the support structure 12 on the side where the side frame 2 receives the exciting force by the beating-up vibration in the width direction. In the present embodiment, the feeding-side height position setting member is selected from among the feeding-side and winding-side height position setting members as the support structure of the present invention. That is, in this frame structure, the height position setting member provided on the delivery side on which the exciting force generated by the beam vibration acts is used as the support structure of the present invention. This frame structure also improves the vibration resistance against beam vibration.

In the frame structure of the present embodiment, the beam support portion 7 corresponding to the beam holder that supports the warp beam 6 is integrally formed in the support structure 12. That is, the frame structure is a structure in which the beam holder is supported by the height position setting member, not the side frame 2. Thus, the exciting force due to the beam vibration does not directly act on the side frame 2, and the frame structure further improves the vibration resistance against the beam vibration.

In the frame structure of the present embodiment, as described above, the position of the bearing 6a in the width direction is the same side as the fixing position to the corresponding side frame 2 in the support structure 12 that supports the bearing 6 a. Thus, the support position of the support structure 12 is on the side of the side frame 2 in the width direction that receives the excitation force caused by the beam vibration, and therefore the frame structure is more effective in improving the vibration resistance against the beam vibration.

While one embodiment of the frame structure of the loom of the present invention has been described above, the frame structure of the loom of the present invention is not limited to the above-described embodiment, and can be implemented by the following modified example.

(1) In the above embodiment, the beam holder for the warp beam 6 is integrally formed in the support structure 12 as the beam holder 7. That is, in the above-described embodiment, in the support structure, the beam holder (the portion functioning as the beam holder) is integrally formed with the height position setting member (the portion functioning as the height position setting member). However, in the frame structure of the present invention, the support structure is not limited to the structure in which the beam holder is integrally formed as described above, and may function as a height position setting member. In this case, in the example of the above embodiment, the support structure is constituted only by the height position setting unit 14 in the support structure 12.

In this case, the beam holder is provided separately from the support structure (height position setting member). In this case, the beam holder may be directly attached to the side frame 2 (supported) in the same manner as in the conventional loom, but may be supported by being attached to a support structure attached to the side frame 2. That is, when the height position setting member on the feeding side is used as the support structure, and when the support structure and the beam holder are separately formed, the beam holder may be provided so as to be attached (supported) to the support structure. In this case, the vibration resistance to the beam vibration can be improved.

(2) The above example is an example in which the height position setting means, that is, the support structure (or including a portion functioning as the height position setting means) is provided on the delivery side. In other words, the height position setting member on the delivery side is used as the support structure described in the present invention. However, in the frame structure of the present invention, the support structure is not limited to the feeding-side height position setting member, and may be a winding-side height position setting member. That is, the frame structure of the present invention may be provided with a height position setting member on the delivery side and/or the winding side as a support structure.

In the above example, the frame structure of the loom is an example in which the height position setting members are provided on the delivery side and the take-up side. However, in the known loom, the frame structure may be configured to include the height position setting member only on one of the delivery side and the take-up side. Therefore, in the present invention, the frame structure may be provided with a height position setting member as the support structure only on one of the feeding side and the winding side.

(3) In the above embodiment, the pair of support structures are fixed to the corresponding side frames 2 such that the side surfaces thereof are in contact with the inner side surfaces 9 of the side frames 2. In other words, the fixing position of each support structure to the corresponding side frame 2 is the inner side surface 9. However, in the frame structure of the present invention, as described above, the fixing position of the support structure on the delivery side and/or the winding side is not limited to the inner side surface 9, and may be an outer surface (outer surface) of the side frame 2 in the width direction.

In the case where the support structures are provided on both the delivery side and the winding side, the fixing positions of the delivery-side support structure and the winding-side support structure may be the same or opposite of the inner surface and the outer surface of the side frame 2. That is, the fixing positions of both the feeding-side support structure and the winding-side support structure may be the inner surface or the outer surface, or one of the fixing positions may be the inner surface and the other fixing position may be the outer surface.

In the case where the height position setting member on the delivery side is the support structure as in the above-described embodiment, when the beam holder is formed integrally with the support structure (or supported by a separate support structure), and when the fixed position is the outer side surface, the warp beam 6 is configured to correspond to the distance between the beam holders in the width direction in this case. In this case, the position of the bearing 6a of the warp beam 6 in the width direction with the warp beam 6 held by the beam holder is outside the side frame 2 in the same manner as the fixed position.

In the case where the height position setting member on the delivery side is the support structure, and the beam holder is separate from the support structure as described above, the position of the beam holder in the width direction with respect to the side frame 2 and the fixed position may not be the same side as described above. That is, the frame structure may be configured such that the beam holder is attached to the outer surface in addition to the fixing position being the inner surface, and the reverse may be possible. In this case, the fixed position in the width direction with respect to the side frame 2 and the position of the bearing 6a are different between the inner side and the outer side.

In addition, in some looms (frame structures), the mounting position of the beam holder to the side frame 2 is not limited to the inner side surface and the outer side surface of the side frame 2, and the beam holder is mounted to the rear surface of the side frame 2. In addition, in the structure of the beam holder itself, even if the beam holder is attached to the inner side surface or the outer side surface of the side frame 2, the guide portion may be formed to protrude further toward the side frame 2 than the portion attached to the side frame 2, and the support surface may be disposed between the inner side surface and the outer side surface of the side frame 2.

In the case of such a configuration, the position of the bearing 6a of the warp beam 6 in the width direction in the state where the warp beam 6 is held by the beam holder is a position between the inner side surface and the outer side surface of the side frame 2. That is, in the frame structure in this case, the position of the bearing 6a in the width direction with respect to the side frame 2 is different from both the inner side surface and the outer side surface of the side frame 2. As described above, the frame structure of the present invention also includes the following structures: in the state where the warp beam 6 is supported by the beam holder, the position of the bearing 6a differs in the positional relationship in the width direction with respect to the side frame 2, either on the same side as the fixed position or on the opposite side as described above.

The present invention is not limited to any of the embodiments described above, and can be modified as appropriate without departing from the scope of the invention.
