Description

  The present invention relates to a loom heald frame and a loom equipped with such a frame.

  It is known that a loom comprises a heald frame intended to be moved vertically up and down by a suitable control device such as some form of dobby. A traditional frame is obtained by assembling two struts (side stays) and two cross members (frame stave), and when the frame is in use configuration, the struts are substantially vertical and cross The member is substantially horizontal. Beneficially, the items can be changed by disassembling the struts and cross members because the struts and cross members of the heald frame are assembled in reverse.

  EP 1540056 (Patent Document 1) discloses a heald frame in which a post and a cross member are assembled using means for fixing the post with respect to the cross member, and the means is located inside one end of the cross member. Describe. In the device, the end of the cross member is externally reinforced by a metal hoop. However, despite the presence of this reinforcing hoop, a substantially static load is applied to the cross member in a configuration in which the struts are fixed with respect to the end of the cross member, thus weakening the structure of the frame. In addition, the mechanical strength of the cross member cannot be improved by increasing the thickness of the lateral part of the hoop because it limits the space available for each heald frame in the direction of the weft of the loom. It is. Further, where the reinforcement hoop is released and the protrusions belonging to the struts can enter the end of the cross member, the cleaning product or woven contaminant is configured such that the struts are disassembled from the cross member during, for example, an item changing action. Tends to enter the volume of the cross member, which helps to weaken the structure of the cross member.

  U.S. Pat. No. 1,922,922 (Patent Document 2) relates to a metal plate in which one end of a cross member forms a column, through the end of the cross member, through the bent end of the column, and through a U-shaped yoke. A heald frame is described that is secured by passing screws and thus tends to weaken both the cross member and the struts.

  The features and advantages of the present invention will become apparent from the following description of three embodiments of the heald frame and loom of the present invention, which description is given by way of example only and with reference to the accompanying drawings.

It is a front view of the heald frame of the loom according to the first embodiment of the present invention. FIG. 2 is an enlarged view of detail II in FIG. 1. FIG. 2 is an enlarged perspective view of an end portion of a cross member of the heald frame of FIG. 1 and a connection casing. It is sectional drawing of IV-IV of FIG. FIG. 3 is a view similar to FIG. 2 of a heald frame according to a second embodiment of the present invention. FIG. 6 is a view similar to FIG. 2 of a heald frame according to a third embodiment of the present invention.

  Next, the present invention will be described based on specific embodiments 1 to 3 with reference to the drawings.

FIG. 1 depicts a heald frame 1 designed to be attached to a loom not depicted. This frame 1 is intended to be moved up and down substantially in the vertical direction by a loom shed forming machine, for example a dobby. The frame 1 is obtained by assembling two struts (side stays) 3 and two cross members (frame stays) 5. In the configuration in which the frame 1 is used, each strut 3 has a longitudinal axis A ₃ upright in the longitudinal direction Z of the longitudinal movement of the frame 1 and each cross member 5 is substantially perpendicular to the direction Z. It has a longitudinal axis A ₅ upstanding in the horizontal direction X.

  Each strut 3 of the frame 1 is substantially a rectangular aluminum piece. As illustrated in FIG. 1, each strut 3 is provided with an attachment 2 in the lower part intended to be connected by a tensioning device not depicted on the piercer to drive the frame 1 vertically up and down. It has been.

The cross member 5 is formed of a synthetic material including a resin and a fiber reinforcing material formed of carbon fiber. Each cross member piece 5 includes a main member 51 having a tubular shape with a rectangular cross section and a lug 59 for supporting the heald slide bar 9. The heddle slide bar 9 is attached to the support lug 59 over substantially its entire length. The main member 51 is hollow and has an opening 53 </ b> A at each end 53. Further, as is particularly clear from FIG. 4, the main member 51 and the support lug 59 are connected together to the wall 54 of the main member 51 so that the frame 1 is in an assembled configuration, that is, the upper cross member 5 of the frame 1. The main member 51 is intended to be positioned facing the other cross member 5 when facing the lower wall of the main member 51. Each cross member 5, extend parallel to the longitudinal axis A ₅ of the cross member, two cutouts are formed in the vicinity of one end 53 of the main member 51 between each is a main member 51 support lug 59 57.

  In the description in which the assembly of the upper cross member 5 of the frame 1 and the post 3 located on the left in FIG. 1 can be seen in more detail, the post 3 located on the left in FIG. Alternatively, the strut 3 located to the right of FIG. 1 is assembled with one or the other of the cross members 5 incorporating the same structural and functional characteristics. In particular, since the frame 1 has a number of symmetry axes, the structure of the means used to assemble each column 3 of the frame 1 and the cross member 5 pair is the upper cross member 5 and the column 3 positioned on the left in FIG. Can be inferred from the means of assembling and the axial symmetry of the structure.

  Further, as can be seen in particular from FIG. 2, the column 3 is assembled with the cross member 5 by means of a connecting casing 7 attached around the end 53 of the cross member 5 adjacent to the column 3. The column 3 is fixed with respect to the cross member 5 by means of screws 8 that fix the column 3 with respect to the casing 7. The frame 1 consists of pins 6 that position the struts 3 with respect to the casing 7, which can redistribute fixed static pressure between the struts 3 and the casing 7 in a configuration in which the struts 3 are assembled with the cross member 5.

  The connecting casing 7 has a U-shaped metal body 71 designed to be closely attached around the end 53 of the main member 51. The main body 51 is formed from, for example, a U-shaped cross section. As shown in FIG. 2, in a configuration in which the casing 7 is closely attached to the end portion 53, the bottom wall 73 of the U-shaped body 71 faces the terminal surface 56 of the end portion 53, and the longitudinal direction X of the cross member 5 Walls 72 and 74 forming a branch of the U-shaped body 71 face the upper wall 53 and the lower wall 54 of the end portion 53, respectively. Since the body 51 is attached around the end 53 and not closely attached to the inside of this end, the thickness of the walls 73, 72 and 74 in the warp yarn direction Y of the frame 1 is effective on the inside of the end 53. It is not limited by the space. In the configuration in which the casing 7 is closely attached around the end portion 53, the lower wall 74 of the main body 71 is accommodated in the cutout 57 of the cross member 5 adjacent to the end portion 53, and the cutout 57 is the end portion 53. And the lug 59 are separated and opened to the terminal surface 56.

In this embodiment, the thickness e ₇ of the bottom wall 73 in the warp yarn direction Y of the frame 1 is substantially equal to the thickness e ₅ of the end 53 in the direction Y. In particular, the thickness e ₇ is larger than the width l ₅ of the opening 53 A at the end 53.

  The casing 7 has two opposing metal walls 75 welded to the side surface of the main body 71, and these metal walls close the side surface of the U-shaped cross section of the main body 71, so that the main body 71 is closely attached to this end 53. In the configuration, it faces the two lateral walls 55 of the end 53. Thus, the casing 7 forms an internal volume that receives the end portion 53, and the end portion 53 is approximately complementary to the internal volume of the casing 7 by the assembly gap. Further, the end surface 56 of the end portion 53 is machined into a form in which it is installed rearward in the longitudinal direction X of the cross member 5 by the length L from the end surface 58 of the end portion of the support lug 59. Thus, attaching the casing 7 closely around the end 53 does not decrease from the useful length of the heald slide bar 9.

  In this embodiment, the casing 7 is held in place by bonding using an adhesive product in a configuration that is mounted around the end 53 of the cross member 5. In the adhesive fixing, the position of the casing 7 can be adjusted in the longitudinal direction X of the cross member 5 with respect to the end 53. This offers the possibility to obtain a very precise length of the frame. Furthermore, the adhesive bond means that the cross member cross-section piece 5 is not weakened. As an option, the casing 7 can be attached to the end 53 by any other suitable means, for example using screws or rivets.

  As shown in FIG. 2, in the configuration in which the column 3 is assembled with the cross member 5, the column 3 is pressed and fixed to the bottom wall 73 of the U-shaped body 71 using the fixing screw 8 and belongs to the column 3. The housing 78 belongs to the casing 7 communicating with the tap housing 38. As will become apparent from the following description, the clamping force of the screw 8 on the housing 38 is opposed to the volume formed between the walls 72 and 74 to accommodate the outer surface of the wall 73, ie the end 53. This has the effect of pressing the support column 3 densely against the surface of the wall of the lever.

  A housing 78 belonging to the casing 7 is formed on the protrusion 77 of the bottom wall 73 of the main body 71 extending on the upper wall 72 of the main body 71. Since the screw 8 is completely housed in the housings 78 and 38, the screw does not pass and therefore the end 53 cannot be weakened.

In the configuration in which the column 3 is assembled with the cross member 5, the central axis A ₇₈ of the housing 78 substantially coincides with the central axis A ₃₈ of the housing 38 of the column 3. In this configuration, the head 28 of the screw 8 presses against the protrusion 77 of the casing 7, and the shaft 83 of the screw 8 is continuously accommodated in the housings 78 and 38, and the external thread 85 of the shaft 83 is connected to the housing. It cooperates with 38 internal tap screws 39.

The central axes A ₃₈ and A ₇₈ of the housings 38 and 78 are inclined with respect to the longitudinal direction X of the cross member 5 and with respect to the longitudinal direction Z of the column 3 in the configuration in which the column 3 is assembled with the cross member 5. In particular, in the depicted example, the axes A ₃₈ and A ₇₈ are parallel to the plane of FIG. 2, ie parallel to the intermediate plane π of the frame 1 formed by the longitudinal directions X and Z of the cross member 5 and the column 3. is there. The axes A ₃₈ and A ₇₈ are not perpendicular to the surface, and the column 3 is supported by the housing casing 7 through the surface. As a result, since the screw 8 is screwed in the housing 78 and 38 which are aligned, resulting in the direction of the arrow F ₁ in FIG. 2 that the relative movement of the column 3 about the cross member 5 is straight upward. The angle defined between the longitudinal axis A ₅ and the axis A ₇₈ of the cross member 5 is denoted α. Within the purpose of this invention, the angle defined between the two axes is formed to be smaller than the two refill angles formed between the two axes. The angle α is in the range between 5 ° and 85 °, preferably about 65 °.

In the configuration in which the support column 3 is assembled with the cross member 5, a cylindrical positioning pin 6 is air-tightly formed in advance on the housing 36 belonging to the support column 3. Therefore, the pin 6 is a continuation of the support 3 and is accommodated in the corresponding cylindrical housing 76 belonging to the casing 7 with a gap, so that the housing 76 communicates with the housing 36. A housing 76 belonging to the casing 7 is formed on the bottom wall 73 of the main body 71 near the lower wall 74 of the main body 71. In the configuration in which the column 3 is assembled with the cross member 5, the central axis A ₇₆ of the housing ₇₆ substantially coincides with the central axis A ₃₆ of the housing 36, with respect to the longitudinal direction X of the cross member 5 and with respect to the longitudinal direction Z of the column 3. It is inclined. In particular, in the depicted example, the axes A ₃₆ and A ₇₆ are parallel to the intermediate plane π of the frame 1 as formed by the cross members 5 and the longitudinal directions X and Z of the columns 3.

The pin 6 inclined with respect to the longitudinal axis A ₃ of the support column 3 can effectively transmit the inertial force between the support column 3 and the casing 7 when the frame 1 is driven up and down in the vertical direction. A casing 7 is provided. Even when the pin 6 actually acts as an obstacle between the column 3 and the casing 7 and the pin extends parallel to the longitudinal direction X of the cross member 5, i.e. when the angle β has a zero value. 3 contributes to transferring the longitudinal inertial force with being inclined with respect to the longitudinal direction Z. Further, the transmission of the inertial force between the column 3 and the casing 7 is optimal by the inclination of the screw 8 with respect to the longitudinal direction X of the cross member 5 and the longitudinal direction Z of the column 3 in the configuration in which the column 3 is assembled with the cross member 5. is there. What actually happens is that the relative movement of the column 3 with respect to the cross member 5 in the direction of arrow F ₁ that occurs when the screw 8 is screwed into the housings 78 and 38 brings the pin 6 into contact with the bottom of the housing 76. . Therefore, the pin 6 is the surface of the pin 6 or the surface of the housing that comes into contact with the pin, and includes a connecting portion between the support column 3 and the casing 7 on the positioning surface S formed by the busbar, that is, the main axis _As6 . In the illustrated example, since the housing 76 and the pin 6 are cylindrical, the main axis A _s6 is the axis of the outer surface of the pin 6 or the inner surface of the housing 76, and the outer surface of the pin 6 or the inner surface of the housing 76 is the other. That is, it is in linear contact with the inner surface of the housing 76 or the outer surface of the pin 6, and this axis A _s6 is parallel to the axes A ₃₆ and A ₇₆ . The angle formed between the longitudinal axis A ₅ and the main axis A _s6 of the cross member 5 is shown in beta. The angle β ranges between 0 ° and 70 °, preferably about 35 °. The connection provided by the pin 6 between the column 3 and the casing 7 on the surface S ₆ redistributes the static pressure resulting from tightening the screw 8 from the column 3 to the casing 7 so that the bottom of the housing 76 faces downward. The pin 6 reacts in the direction of the arrow F ₂ in FIG. Furthermore, while the screw 8 is being screwed in, the screw 3 brings the post 3 into contact with the bottom wall 73 of the casing 7 along a surface that is not perpendicular to the axis of the screw shaft 83, so that an appropriate space between the fixing screw 8 and the housing 78 can be obtained. Because of the tight clearance, these surfaces cause relative movement in the direction Z while the screw 8 is tightened, and some of the forces involved in tightening the screw 8 are in contact between the pin 6 and the housing 76 of the casing 7. To pass through.

According to a not-illustrated alternative embodiment of the invention, the cylindrical pin 6 is preformed in an airtight manner in the housing 76 of the casing 7. At this time, the pin 6 is a continuation portion of the casing 7 that can be accommodated in the corresponding cylindrical housing 36 that belongs to the column 3 and communicates with the housing 76. In this case, in the configuration in which the column 3 is assembled with the cross member 5, the pin 6 provides a connecting portion between the column 3 and the casing 7 on the positioning surface, and the main axis of the positioning surface is the outer surface of the pin 6 or the housing. 36, the outer surface of the pin 6 or the inner surface of the housing 36 is in linear contact with the other, ie, the inner surface of the housing 36 or the outer surface of the pin 6, and this axis is the axis A ₃₆ and A ₇₆ . Parallel.

Beneficially, the value of angle β is less than the value of angle α. Substantially when the longitudinal reaction force exerted by the pin 6 through the bottom of the housing 76 is actually maximized due to the small value of the angle β or the high value of the angle α, the value of the angle β is substantially smaller than the value of the angle α. This means that a longitudinal inertia force can be transmitted between the support column 3 and the casing 7. Relative layout of the positioning surface S ₆ and the screw 8, more particularly that the main axis A _S6 of the positioning surface S ₆ is inclined with respect to the longitudinal direction X of the cross member 5 and that the screw 8 is at least partially accommodated in one quadrant. The same angle quadrant, i.e., the plane P ₀ where the sector Q is perpendicular to the longitudinal direction Z of the column 3 on the one hand and passes through the intersection O of the axis A ₃₆ -A _{78 of the} screw 8 and the main axis A _S6 , Then, the fact that it is formed between the plane P ₁ perpendicular to the longitudinal direction X of the cross member 5 and passing through the intersection is that between the pin 6 and the housing 76 of the casing 7 when the screw 8 is tightened. The support column 3 is brought into contact with the casing 7 by the reaction force caused by the contact.

Another definition of a useful relative layout of the screw 8 and the positioning surface S ₆ is given on the basis of angle considerations, with the strut 3 in contact with the casing 7 when the screw 8 is tightened. Therefore, the axis A ₀ is parallel to the longitudinal direction X of the cross member 5 and passes through the intersection point O of the axis A ₃₆ -A _{78 of the} screw 8 and the main axis A _S6 . The useful relative layout of the screw 8 and the positioning surface S ₆ is the angle measured counterclockwise from the axis A ₀ to the axis A ₃₆ -A _{78 of the} screw 8 and the main axis A of the positioning surface S ₆ from the axis A _{0. The} angle measured counterclockwise up to _S6 is both the angular range [0 °; 90 °], or the angular range [90 °; 180 °], or the angular range [180 °; 270 °], or the angular range. [270 °; 360 °].

  In order to manufacture the frame 1, the two cross members 5 of the frame 1 are first prepared by providing the connecting casing 7 at each two ends 53 of each cross member section piece 5. To do this, it is mounted closely around the end 53 as depicted by arrow E in FIG. 3, with the casing bottom wall 73 facing the end face 56 of the end 53 and the casing walls 72 and 74. Are respectively positioned so that the side wall 75 of the casing 7 faces the side wall 55 of the end part 53. As shown in FIG. 4, the casing 7 is closely attached to the end portion 53 by, for example, bonding using an adhesive product that fills a gap between each pair of opposed surfaces belonging to the casing 7 and the end portion 53. Fixed in this configuration. In particular, this connection can be achieved by applying an adhesive product to the outer surfaces of the walls 52, 54, 56 and 55 of the end 53 before attaching the casing 7 closely to the end 53.

  The cross member 5 including the connection casing 7 can be reversibly assembled with the support column 3. Therefore, the item can be easily changed by disassembling one or both of the two columns 3 with respect to the cross member 5 of the frame 1, and remains in an appropriate position on the cross member 5 when the frame 1 is in the disassembled configuration.

One method of assembling the cross member 5 of the frame 1 with the connecting casing 7 and the column 3 of the frame 1 includes the following steps:
All of the two pins 6 which are securely pre-mounted in the two holes 36 of the column 3 are positioned in the housing 76 of the casing 7 of the corresponding cross member 5. To do this, the end portions 53 of the two cross members 5 are moved apart in the longitudinal direction Z, and then two pins 6 that are orthogonal along their respective inclined axes A ₃₆ are respectively connected to the upper cross member. 5 is inserted into the corresponding housing 76 in the casing 7 attached to the lower cross member 5. The necessary separation of the end 53 of the cross member 5 in the direction Z has an appropriate value that can be achieved even when the other strut 3 is already assembled with the cross member 5 and the heald is installed in the heald sidebar. Designed.

  For each cross member 5, the fixing screw 8 is introduced into the housing 78 in the corresponding casing 7 and the screw 8 is screwed into the housing 38 of the column 3, so that the external thread 85 of the shaft 83 is an internal tap of the housing 38. It works with the screw 39. When the screw 8 is tightened, the screw head 81 is supported by the protrusion 77 of the casing 7. The screw 8 is easy to tighten, because the preceding process of positioning the pin 6 pre-mounted on the column 3 in the housing 76 belonging to the casing 7 of the two cross members 5 is the housing of the casing 7 of the cross member 5. This is because 78 is aligned with the interlocked housing 38 of the column 3.

In the second embodiment depicted in FIG. 5, elements similar to those of the first embodiment support an equal sign increased by 100. The heald frame 101 according to this second embodiment partly depicted in FIG. 5 is intended to comprise a loom not depicted. The frame 101 is obtained by assembling two columns 103 and two cross members 105. In FIG. 5, one column 103 and one cross member 105 can be seen. The frame 101 is designed to be driven up and down substantially in the vertical direction by the shed forming machine. In a configuration in which the frame 101 is used, each column 103 has a longitudinal axis A ₁₀₃ that is substantially perpendicular to the longitudinal direction Z in which the frame 101 is moved up and down, and each cross member 105 is perpendicular to the direction Z. And a longitudinal axis A ₁₀₅ orthogonal to the direction X which is substantially horizontal.

  The column 103 and the cross member 105 of the frame 101 have a structure similar to the column 3 and the cross member 5 of the frame 1 of the first embodiment. In particular, as seen in FIG. 5, a main member 151 in which each cross-member cross-section piece 105 is a tube having a rectangular cross section, and a lug 159 that supports a heald slide bar 109 attached to a support lug 159 that extends over substantially the entire length. Have The main member 151 and the support lug 159 are positioned facing the other cross member 105 when the frame 101 is assembled, that is, the lower wall 154 of the main member 151 in the case of the upper cross member 5 of the frame 101. Are joined together at the wall 154 of the main member 151 which is intended to be.

  FIG. 5 depicts only means for assembling the upper cross member 105 of the frame 101 and the column 103 positioned to the left of the frame 101 depicted in FIG. However, as in the first embodiment, the structure of the means used to assemble the other struts 103 and the cross member 105 pair of the frame 101 is inferred by axial symmetry from the structure of the assembly means shown in FIG. obtain.

  The means for assembling the cross member 105 and the column 103 comprises a connecting casing 107 similar to the casing 7 of the first embodiment, and is closely attached around the end 153 of the member 151 adjacent to the column 103. The connecting casing 107 is formed of a U-shaped metal body 171, and the bottom wall 173 of the main body is positioned facing the end surface 156 of the end 153 in a configuration in which the casing 107 is closely attached to the end 153. Walls 172 and 174 forming branches of the body 171 are positioned facing the upper wall 152 and the lower wall 154 of the end 153, respectively. As in the first embodiment, the lower wall 174 of the main body 171 is housed in the cutout 157 of the cross member 105, and the cutout separates the end 153 and the lug 59 and opens to the end face 56. Further, the bottom wall 173 is solid, and the thickness of the frame 101 in the direction Y of the warp is substantially equal to the thickness of the end 153 in the direction Y. Therefore, the width of the opening 153A of the end 153 where the thickness of the bottom wall 173 increases in the direction Y is larger. Further, the casing 107 is composed of two metal walls 175, each wall being welded to one lateral surface of the main body 171, and the two lateral surfaces of the end portion 153 in a configuration in which the casing 107 is closely attached to the end portion 153. Facing.

As can be seen in FIG. 5, the frame 1 according to this second embodiment is particularly equipped with cross-member cross-sections for each attachment 102 that attaches the frame 101 to the tensioning device so that the frame 101 can be driven up and down by the piercer. It is different from the frame 1 by being attached to the cross member 105 in the casing 107. In particular, in this embodiment, each attachment 102 is fixed to one of the two casings 107 provided with the upper cross member 105 of the frame 101. For this purpose, each casing 107 of the upper cross member has a tap housing 177 formed on the upper wall 172 of the U-shaped body 171, each housing intended to receive a screw 121 that secures the attachment 102. Has been. Beneficially, the upper wall 172 of the U-shaped body 171 has a length L ₁₇₂ that is greater than the length L ₁₇ of the lower wall 174 of the U-shaped body 171. Fixing each attachment 102 directly to the casing 107 means that the cross member cross-section piece 5 is not weakened.

  In particular, as an option according to the configuration of the tensioning device, each attachment 102 of the frame 101 can be fixed to one of the two casings 107, and the lower cross member 105 of the frame comprises a casing. In another optional aspect, each attachment 102 is formed as an integral member of the corresponding casing 107.

The column 103 is fixed with respect to the cross member 105 including the casing 107 by using a screw 108 that fixes the column 103 pressed against the bottom wall 173 of the casing 107. In the same manner as in the first embodiment, the fixing screw 8 is inserted into the housing 178 belonging to the casing 107 formed on the bottom wall 173 near the top wall 172 and in the structure in which the column 103 is assembled with the cross member 105. 103, and is accommodated in a tap housing 138 communicating with the housing 178. At this time, the central axis A ₁₇₈ of the housing ₁₇₈ substantially coincides with the central axis A ₁₃₈ of the housing 138. The screw 108 does not pass and therefore does not weaken the end 153. As in the first embodiment, the strut 103 is pressed against the outer surface of the bottom wall 173 facing the volume that houses the end 153 between the walls 172 and 174 by screws. However, in this second embodiment, the head 181 of the screw 108 is supported by the column 103 rather than the casing as in the previous embodiment, and the shaft 183 of the screw 108 is continuously housed in the housings 138 and 178. The external thread 185 of the shaft 183 cooperates with the internal tap screw 139 belonging to the housing 178. The central axes A ₁₃₈ and A ₁₇₈ of the housings 138 and 178 are inclined with respect to the longitudinal direction X of the cross member 5 and the longitudinal direction Z of the strut 103 in a configuration in which the strut 103 is assembled with the cross member 5, in such a manner. In the direction of arrow F ₃ in FIG. 5 where screwing screw 108 into aligned housings 138 and 178 is directed downward, it causes relative movement of strut 103 with respect to cross member 105. The angle formed between the axis A ₁₇₈ and the longitudinal axis A ₁₀ of the cross member 105 is indicated by α ′. The angle α ′ ranges between 5 ° and 85 °, preferably on the order of 45 °.

Further, the frame 101 comprises positioning pins 106 for positioning the column 103 with respect to the casing 107. A cylindrical pin 106 is airtightly installed in advance on a housing 136 belonging to the column 103, and the column 103 is formed on the bottom wall 173 of the casing 107 near the lower wall in a configuration in which the column 103 is assembled with the cross member 105. It is housed in a corresponding cylindrical housing 176 that communicates. In the configuration in which the column 103 is assembled with the cross member 105, the center axis A ₁₇₆ of the housing 176 substantially coincides with the center axis A ₁₃₆ of the housing 136, and is inclined with respect to the longitudinal direction X of the cross member 105 and the column 103 longitudinal direction Z. Has been.

As in the first embodiment, the pin 106 inclined with respect to the longitudinal axis A ₁₀₃ of the support column 103 is connected to the support member 103 and the cross member 105 via the casing 107 when the frame 101 is driven up and down in the vertical direction. Allows effective transmission of inertial force. In the configuration in which the column 103 is assembled with the cross member 105, the inclination of the screw 108 with respect to the longitudinal direction X of the cross member 105 and the longitudinal direction Z of the column 103 can similarly transmit the optimum inertia force between the column 103 and the cross member 105. This is because the relative movement of the column 103 with respect to the cross member 105 in the direction of the arrow F ₃ pointing downward when the screw 8 is tightened brings the pin 106 into contact with the bottom of the housing 176. Just as in the first embodiment, a surface of the housing 176 in contact with the surface or their surface of the pin 106 and bus, i.e. pin 106 in the positioning surface S ₁₀₆ consisting of the main axis A _S106 are between the mounting posts 103 and the casing 107 A connecting part is provided. Since the housing 176 of the pin 106 is cylindrical, the main axis _{AS 106} is an axis on the outer surface of the pin 106 or the inner surface of the housing 176, and the outer surface of the pin or the inner surface of the housing is the other of these surfaces, that is, the inner surface of the housing 176 or outer surface linearly contact pin 106, the axis a _S106 is parallel to the axis a ₁₀₃ and a _176. The angle formed between the main axis A _S106 and the longitudinal axis A ₁₀₅ of the cross member 105 is denoted β ′, this angle β ′ ranges between about 10 ° and 75 °, preferably 35 °. Degree. Due to the reaction of the bottom of the housing 176 with respect to the pin 106 in the direction of the arrow F _{4 in} FIG. 5 where the connection provided by the pin 106 is facing upwards on the surface S ₁₀₆ between the column 103 and the casing 107. From the static pressure resulting from tightening the screw 108 to the bottom wall 173 of the casing 107 leads to redistribution.

Further, as in the first embodiment, the relative layout of the positioning surface _S106 and the screw 108 causes the column 103 to contact the casing 107 when the screw 108 is tightened. More particularly, the positioning surface S ₁₀₆ and the screw 108 are at least partially contained in one quadrant, the same angular quadrant Q is on the one hand perpendicular to the longitudinal direction Z of the column 103 and the main axis _{AS 106} and the axis of the screw 108. is formed between the plane P ₁ passing through and the intersection O is perpendicular to the longitudinal direction X of the plane P ₀ and the cross member 105 which passes through the intersection O between the a _138- a _178.

  As in the first embodiment, the frame 110 is formed by mounting and fixing, for example, a coupling casing 107 around each of the two ends 153 of each cross member 105. At this time, the cross member 105 including the casing 107 can be assembled with the support column 103 in reverse.

The pillars 103 of the frame 101 are assembled with the cross member 105 of the frame 101 having the connecting casing 107 in the same manner as in the first embodiment by positioning each of the two pins 106, and the pins correspond to the corresponding cross members 105. Are installed in advance in the two holes 136 of the column 103 in the housing 176 belonging to the casing 107. In order to do this, the end portions 153 of the two cross members 105 are brought together closely in the longitudinal direction Z of the column 103, and then the two pins 106, which go straight along their respective tilt axes A ₁₃₆ , It is introduced into the corresponding housing 176 belonging to the casing 107 fixed to the cross member 105. Since the fixing screw 108 is inserted into each housing 138 of the column 103 and the screw 108 is screwed into the housing 178 belonging to the casing 107 of the corresponding cross member 105, the external thread 185 of the shaft 183 is connected to the internal tap screw 179 of the housing 178. Work together. Tightening the screw 108 causes the screw head 181 to be supported on the support column 103.

In the third embodiment depicted in FIG. 6, elements similar to those of the first embodiment support the same reference number increased by 200. Two struts 203 having a structure similar to the strut 3 and the cross member 5 of the frame 1 of the first embodiment are intended to include a loom in which the heald frame 201 partially depicted in FIG. 6 is not depicted. And two cross members 205 are assembled. As in the previous embodiment, the frame 201 is designed to be moved vertically in the vertical direction by the shed forming machine, and in the configuration in which the frame 201 is used, each support column 203 is substantially perpendicular to the vertical direction Z. The longitudinal axis A ₂₀₃ has a longitudinal axis A ₂₀₃ , the frame 201 moves up and down in the longitudinal direction Z, and each cross member 205 is perpendicular to the direction Z and is orthogonal to the direction X which is substantially horizontal. ₂₀₅ .

  FIG. 6 depicts only the means for assembling the post 203 positioned to the left of the frame 201 and the upper cross member 205 of the frame 201 in the depiction of FIG. It will be understood that the structure of the means used for assembly can be deduced by axial symmetry from the structure of the assembly means shown in FIG. The means for assembling the strut 203 and the cross member 205 are closely attached and fixed, for example similar to the casing 7 of the first embodiment by coupling around the end 253 of the main member 251 of the cross member 205 adjacent to the strut 203. It consists of a connecting casing 207.

  The connecting casing 207 is made of a U-shaped metal body 271, and the bottom wall 273 of the main body is positioned facing the end surface 256 of the end 253 in a configuration in which the casing 207 is closely attached to the end 253, and is U-shaped. Walls 272 and 274 forming branches of the body 271 are positioned facing the upper wall 252 and the lower wall 254 of the end 253, respectively. The lower wall 274 of the main body 271 is accommodated in the cutout 257 of the cross member 205, and the cutout separates the end 253 of the cross member 205 and the support lug 259, and the heald slide bar 209 is attached to the support lug. . The thickness of the bottom wall 273 in the direction Y of the warp yarn of the frame 201 is substantially equal to the thickness of the end portion 253 in the direction Y, because the thickness of the bottom wall 273 in the direction Y is the width of the opening 253A of the end portion 253 as well. Means greater than. Further, the casing 207 is composed of two metal walls welded to the lateral surface of the main body 271, and the lateral surface of the main body faces the two lateral walls of the end portion 253 in a configuration in which the casing 207 is closely attached to the end portion. Yes.

As shown in FIG. 6, the frame 201 is different from the frame 1 of the first embodiment in that the support column 203 has an upper recess 231 that can accommodate the protruding portion 273 </ b> A of the bottom wall 273 of the casing 207 by replenishment of the shape. is doing. The recess 231 is formed near the lower portion, that is, the lower wall 274 of the casing 207 when the portion 273A is housed in the recess 231 by the positioning slope 236 that positions the column 203 with respect to the casing 207. Slope 236 cooperates with a corresponding slope 273 defined by portion 273A of casing 207. In the configuration in which the column 203 is assembled with the cross member 205, the quasi-line A _{236 of the} inclined surface 236 considered in parallel with the intermediate plane of the frame 201 is considered in parallel with the intermediate plane of the frame 201 and the longitudinal direction X of the cross member 205 This corresponds to the quasi-line A ₂₇₆ of the inclined surface 276 that is inclined with respect to the longitudinal direction Z of the column 203 and the embodiment.

In the same method as in the first embodiment, in the configuration in which the column 203 is fixed with respect to the cross member 205 by the fixing screw 208 and the column 203 is assembled with the cross member 205, the fixing screw is housed in the housing 278 belonging to the casing 207. Thus, a protrusion 277 on the bottom wall 273 near the top wall 272 of the main body 271 and a tap housing 238 belonging to the column 203 and communicating with the housing 278 are formed. The screw 208 does not pass through the end portion 253 and presses the column 203 against the outer surface of the bottom wall 273. In the assembled configuration, the central axis A ₂₇₈ of the housing ₂₇₈ substantially coincides with the central axis A ₂₃₈ of the housing 238, and the head of the screw 208 is supported by the protrusion 277. The central axes A ₂₃₈ and A ₂₇₈ of the housings 238 and 278 are inclined with respect to the longitudinal direction X of the cross member 205 and the longitudinal direction Z of the support 203 in the configuration in which the support 203 is assembled with the cross member 205, so that the screw 208 is aligned. when screwed to the housing 238 and 278, provided in the direction of arrow F ₅ in FIG. 6 the relative movement of the strut 203 about the cross member 205 is directed upward. Formed between longitudinal axis A ₂₀₅ and axis A ₁₇₈ of cross member 205, the angle is indicated by α ″. Angle α ″ ranges between 5 ° and 85 °, preferably on the order of 65 °. is there.

As in the previous embodiment, the co-operation between the slopes 236 and 276 that are inclined with respect to the longitudinal axis A ₂₀₃ of the column 203 is such that when the frame 201 is driven up and down vertically, the column 207 is moved through the casing 207. It is possible to effectively transmit the inertia force between 203 and the cross member 205. Further, in a configuration in which the support column is assembled with the cross member, when the screw 208 is tightened due to the inclination of the screw 208 with respect to the longitudinal direction X of the cross member 205 or the longitudinal direction Z of the support column 203, the arrow F ₅ pointing upwards In the direction, the relative movement of the column 203 with respect to the cross member 205 presses the positioning ramp 236 of the column 203 to bring the casing 207 and ramp 276 into firm contact. Therefore, the column 203 and the casing 207 are positioned on the positioning surface S ₂₃₆ which is the surface of the inclined surface 236 so that the positioning inclined surface 236 is in contact with the surface of the inclined surface ₂₃₆ and is composed of the principal axis, that is, the quasi-line A _{236 of the} inclined surface ₂₃₆ . A connecting portion is provided between the two. The angle formed between the longitudinal axis A ₂₀₅ and the main axis A ₂₃₆ of the cross member 205 "is shown in. The angle beta" beta is preferably in the range between about 0 ° and 75 ° 35 Degree of °. This connecting portion provided by the positioning slope 236 between the support column 203 and the casing 207 on the surface S ₂₃₆ is the downward direction of the slope 236 of the support column 203 and the slope 276 of the casing 207 in the direction of arrow F _{6 in} FIG. The reaction leads to a redistribution of static pressure resulting from tightening the screw 208 from the post 203 to the bottom wall 273 of the casing 207.

Furthermore, as in the first embodiment, the relative movement of the positioning surface S ₂₃₆ and the screw 208 is contained in one quadrant, while being perpendicular to the longitudinal direction Z of the column 203 and the main axis _{AS 206} and the screw 208. plane P ₀ and the same ring 207 formed between the plane P ₁ longitudinal direction X in a vertical and passing through the intersection O of the cross member 205 which passes through the intersection O between the axis a _238- a ₂₇₈ with Make firm contact with ramp 276. Therefore, the positioning slope 236 facilitates the surface of the slope 236.

  As is clear from the above three embodiments, the cross-member cross-section pieces 5, 105, 205 of the heald frames 1, 101, 201 according to the present invention are not subjected to static pressure for fixing the columns in the configuration in which the frames are assembled. This is because there is a connecting casing 7, 107, 207 that is attached to each cross member in the area of assembly with the struts and absorbs all the static pressure that results from the fixation of the struts with respect to the cross member. This advantage is obtained even if the fixing member and / or the positioning surface is not inclined with respect to the direction X or the direction Z. This in turn results in a better mechanical integrity of the frame according to the invention and in particular a better mechanical integrity of the cross member compared to prior art heald frames. As a result, the heald frame according to the invention is robust and can be used on very high speed looms.

  More particularly, the part of this wall in which the static pressure resulting from the fixing of the column with respect to the cross member lies between the bottom wall of the casing 7, 107, 207, between the bottom wall and the fixing member, in particular the fixing screw, the bottom wall and the positioning member of the above example. The area of contact between them, in particular the positioning bevels in the above example, i.e. the pins, is absorbed and this bottom wall is continuous, solid and very strong. In particular, according to an example of means for assembling the support and cross member of the heald frame according to the present invention, the upper walls 72, 172, 272 and the lower walls 74, 174, 274 and the lateral walls 75, 175, 275 of the casings 7, 107, 207 are crossed. The member cannot receive the fixed static pressure of the column. As a result, the thickness of the transverse walls 75, 175, 275 can be fixed, and in the given effective space for the frame in the warp direction X, each cross member cross-section piece of the heald frame according to the invention is prior art. It can have a width in the direction X that is greater than the width of the cross member cross-section of the frame, and therefore has a better bending strength.

  Furthermore, the U-shaped cross-sections of the connecting casings 7, 107, 207 attached around the ends of the cross member of the heald frame according to the present invention are connected to the connecting casing when the frame is driven vertically up and down. It helps to effectively transmit the inertial force between the cross member cross-section pieces. Whatever the fixing mode of the attachment 2 or 102 to the frame, frame support or cross member of the shed forming machine, the inertial force is selectively between the upper wall of the U-shaped body and the upper wall of the cross member. And between the lower wall of the U-shaped body and the lower wall of the cross member. These opposing inertial force transmission surfaces extend across the entire thickness of the end portions 53, 153, 253 of the cross member in the direction X of the vertical movement and in the direction X of the warp, that is, have an optimum surface area. It is possible to optimize the contact area between the walls 74, 174, 274 and the cross-member cross-section by the presence of the cutouts 57, 157, 257. The reciprocating longitudinal force is transmitted between the strut and the cross member according to the invention in an optimized manner without any risk of the casing 7, 107, 207 being torn.

Furthermore, the relative layout of the positioning surface and the fixing member of the frame according to the invention, and more particularly the positioning surface and the fixing member are at least partly contained in one quadrant, while being perpendicular to the longitudinal direction Z of the column and The same plane formed between the plane P ₀ passing through the intersection O between the main axis of the positioning surface and the axis of the fixing member and the plane P ₁ perpendicular to the longitudinal direction X of the cross member and passing through the intersection O on the other side The angular quadrant facilitates bringing the strut into contact with the bottom wall of the casing 7, 107, 207 when the screw is screwed. The presence of positioning members in each region of the strut and cross member assembly allows the cross member to be accurately positioned with respect to the strut in the warp yarn direction Y, thus limiting the frame crisis according to the present invention to capture in adjacent frames, It allows an accurate relative positioning of the two cross members of the frame at Z, so that once the post is fixed, it ensures good control over the space of the two heald slide bars 9, 109, 209.

  The openings 53A, 153A, 253A at the two ends of each cross member of the frames 1, 101, 201 according to the present invention are closed by the bottom walls of the two connecting casings 7, 107, 207 as a whole, and the cross member serves as the connecting casing. And is reinforced by a solid U-shaped body and the lateral walls of the casing, which are designed to remain in place on the cross member in a configuration in which the struts are disassembled from the cross member. Thus, the cross member is protected from any damage or any contamination that adversely affects the structure of the cross member at the ends.

  The invention is not limited to the examples described and depicted. In particular, each connecting casing 7, 107, 207 of the cross member of the frame according to the invention formed from a U-shaped cross-section closed at the side by two lateral walls was formed from a single U-shaped cross-section without side walls. Replaced by the connecting element, this U-shaped connecting element is attached intimately around the end of the cross member. Since the thickness in the direction Y of the warp yarn of the bottom wall of the U-shaped cross-section connecting element such as a U-shaped cross section without a side wall is equal to or greater than the width in the direction Y of each end opening of the cross member, The bottom wall can close this opening.

  In the case of the casings 7, 107, 207 connected to the lateral walls 75, 175, 275 as illustrated in the drawing, one of the lateral walls of the casing is attached to the support lug of the cross member as indicated by a dotted line in FIG. Continuous along and forming an additional bond interface between the casing and the cross member. The bottom walls 73, 173, 273 of the connecting casing have a thickness in the direction Y of the warp that is greater than the thickness in the direction Y of the end portions 53, 153, 253 of the cross member.

  Further, in the first two embodiments, when the positioning pins are in the housings 76 and 176 of the connecting casings 7 and 107 before the columns and cross members are assembled, the positioning pins 6 and 106 are positioned in the column housings 36 and 136. Pre-installed securely and easily. The housings 76 and 176 that accommodate the pins 6 and 106 in the casings 7 and 107 do not open on the side surfaces of the cross member cross-section pieces 5 and 105. In all cases, the thickness of the bottom walls 73, 173 of the casings 7, 107 in the warp direction Y of the frames 1, 101 is greater than the width of the openings 53A, 153A at the end of the cross member in the direction Y, so When in the assembled configuration, the casing 7, 107 closes the end of the cross member. When the housing 76, 176 containing the pins is a non-emergency housing, or when the pins are firmly installed in the housing, the end of the cross member is closed in a configuration in which the post is separated from the cross member. . Moreover, in any embodiment, the number of fixing members associated with each connecting element 7, 107, 207 is greater than one.

In the casings 7 and 107 used to connect the cross members, the attachments 2 and 102 for connecting the frame to the tensioning device are formed in spite of the angular quadrant formed between the planes P ₀ and P _1. Or it has the code | symbol equal to a support | pillar, and a positioning surface and a fixing member lie in those planes. The connection attachments 2, 102 can be fixed to the connection casing, in particular using the positioning surface and fixing member layout shown in the first embodiment, or optionally the positioning surface and fixing shown in the second embodiment. It can be fixed to the column by the layout of the member.

Furthermore, the present invention is described by connecting casings 7, 107, 207, wherein the angular gradients β, β ′, β ″ of the main axes of the positioning surfaces S ₆ , S ₁₀₆ , S ₂₃₆ are crossed with respect to the longitudinal axis of the cross member. With respect to the longitudinal axis of the member, it is smaller than the angular gradient α, α ′, α ″ of the axis of the fixing member 8, 108, 208. However, redistribution of the static pressure fixing force from the column to the casing 7, 107, 207 is obtained, the fixing member is inclined with respect to the surface, the column is supported by the casing via the surface, and the positioning member is the casing at the positioning surface. Promote. In particular, the angle values β, β ′, β ″ are larger than the angle values α, α ′, α ″.

Further, the present invention describes the relative layout of the positioning member and the fixing member, and the main axes of the positioning surfaces S ₆ , S ₁₀₆ , S _{236 and} the axis of the fixing members 8, 108, 208 are the frames 1, 101, 201. Is parallel to the intermediate plane π. As an option, these axes are not parallel to the plane π. In this case, the angular gradients α, α ′, α ″ and β, β ′, β ″ correspond to the longitudinal direction X of the cross members 5, 105, 205 and the axis of the fixing member and the main axis of the positioning surface, respectively. It is formed between the orthogonal projections on the plane π. The criteria matched by the beneficial relative layout of the positioning surface of the frame and the fixing member according to the invention is such that in the configuration in which the strut is assembled with the cross member, the fixing member and the positioning surface are at least partially contained in one quadrant, in the plan P ₀ and the other the same angle quadrant in one pass through the intersection O of the cross projection and the axis of the longitudinal direction Z in a vertical and fixed member and the main axis of the positioning surface with respect to the intermediate plane π of the frame struts It is formed between the plane P ₁ perpendicular to the longitudinal direction X of the cross member and passing through the intersection O. In other words, the useful relative layout of the positioning surface of the frame and the fixing member according to the invention is measured counterclockwise from the axis A _0, which is clearly defined only for the orthogonal projection of the axis of the fixing member to the intermediate plane π of the frame. And the angle measured counterclockwise from the axis A ₀ is limited to the angular range [0 °; 90 °] or the angular range [only in the orthogonal projection of the main axis of the positioning surface to the intermediate plane π of the frame. 90 °; 180 °] or angular range [180 °; 270 °] or angular range [270 °; 360 °].

  Finally, the connecting casing for the heald frame according to the invention can be attached to any type of cross-member cross-section, in particular a cross-member cross-section made of aluminum, steel, synthetic material or some other material. The geometry of the cross-member cross-section of the heald frame according to the invention that receives the connecting casing is different from that described above. In particular, the main members 51, 151 and 251 of the cross member have an I-shaped cross section. The heddle slide bars 9, 109, 209 can be connected to the cross member by means other than the support lugs belonging to the cross member.
