Definitions

  • the invention relates to a shaft rod in particular for a heald a loom not too fast running.
  • shaft rods In the interest of a cost-effective provision of looms is sought to produce shaft rods cost.
  • shaft rods today consist of light metal hollow chamber profiles in order to achieve high rigidity with low weight.
  • the effort required to produce shaft rods is usually relatively high.
  • the U.S. Patent 4,633,916 a shaft rod, which consists of several metal profiles, which between each other a rectangular cross-section hollow chamber define that is filled with honeycombs.
  • a stiffening profile is arranged on a narrow side of this hollow chamber. The parts are glued together.
  • the U.S. Patent 4,508,145 discloses a shaft rod with a roll-profiled, in cross-section U-shaped sheet metal profile whose legs are connected to a mounting rail carrier. The other end of the mounting rail carrier holds the heald support rail for receiving strands.
  • the junction between the Litzentragschienen19 and the U-shaped metal profile represent a vulnerability.
  • the serving for receiving the strands edge is usually not equal to the resulting requirements here.
  • such shaft rods have a considerable weight with limited rigidity.
  • the CH 286 827 also discloses a consisting of sheet metal bending shank rod, which is formed by two mutually mirror-symmetrical bent sheet metal parts which are interconnected. The result is a hollow chamber profile with two marginal and a large central hollow chamber. Overall, such a shaft rod is relatively heavy.
  • a shaft rod known which consists of a single sheet metal part.
  • the ends are each folded to T-profile-shaped edges, while the middle part is formed in the manner of a corrugated sheet with longitudinal waves.
  • Such a shaft rod has an insufficient rigidity for today's requirements.
  • the shaft rod according to the invention has a rod body which inherently has the desired flexural rigidity. It is formed by a single longitudinally continuous sheet metal part having an upper, longitudinally extending edge and a lower, also extending in the longitudinal direction edge. Between the edges, the sheet metal bending part has a hollow chamber-free flat central portion, which gives the rod body in combination with the edges of the desired stiffness. The hollow chamberless level central portion holds the upper edge and the lower edge of the rod body at a defined distance from each other. This results in a relatively low weight improved stiffness of the shaft rod compared to known from the prior art, consisting of a single sheet metal shaft rods.
  • the hohlhuntlose planar central portion also comes with relatively little volume of material and thus despite a particularly simple structure with a relatively low weight.
  • the hollow chamber-less central portion consists of two, for example, flat superimposed walls, which are connected to each other in a continuous or sectional manner.
  • the connection can be made by surface bonding, riveting, point or line welding or similar measures.
  • the hollow chamber-less central portion consists only of a single wall of sufficient strength.
  • the wall preferably extends without interruption from the upper edge to the lower edge. By avoiding openings and breakthroughs both in the edges and in the wall, a relatively high load capacity can be achieved.
  • the upper edge is formed by a stiffening means, which preferably extends without interruption over the entire length of the shaft rod.
  • the stiffening means may be formed by a hollow chamber, which is formed by the sheet metal part of the rod body.
  • the hollow chamber can by a continuous over the entire length of the stiffening agent weld or, if necessary, by other means be closed. An uninterrupted weld along the entire length leads to a high degree of stability.
  • the stiffening means may be formed by a solid rod connected to the sheet metal part.
  • the rod may be made of a metal or also of e.g. be formed fiber reinforced plastic. Depending on the choice of material, welded connections or even adhesive connections can be used for the connection.
  • a further stiffening means e.g. may be formed by the Litzentragschiene.
  • the heddle support rail can be formed in the simplest case by an angled edge of the sheet metal bent part. Alternatively, a bent from a sheet metal hanger rack welded to the sheet metal part or connected by other means with this. This opens up the possibility of choosing different types of steel for the heddle support rail and the bent sheet metal part, the choice of different material thicknesses and other design degrees of freedom.
  • the rod body is insofar a sheet metal part, which can be produced for example by roll forming or by bending a cut sheet metal strip.
  • This sheet metal part is preferably provided at its ends with connecting means for side supports.
  • These connection means are preferably made without larger openings in the sheet metal part.
  • As a connection means further sheet metal parts can be provided which form open-sided pockets on the rod body, for example. Each pocket is preferably open on two opposite sides. In these bags can Side supports provided corner pieces are inserted and clamped in them by means of a clamping screw. If the pockets are likewise open at their end remote from the rod end, the corner piece can engage behind an edge of the pocket and thus form a form-fitting pull-out protection. It is also possible to close the pockets at their end remote from the end of the rod.
  • FIG. 1 a heald 1 is illustrated, which has an upper shaft rod 2, a lower shaft rod 3 and side supports 4, 5.
  • the shaft rods 2, 3 and side supports 4, 5 are connected to each other to form a rectangular frame, which is vertically moved up and down in operation by not further illustrated drive means.
  • He carries healds 6 for guiding warp threads in a loom.
  • On the shaft rods 2, 3 sit, for example, made of wood guides 7 to keep adjacent healds at a distance.
  • the guides 7 may be replaced by other means.
  • the shaft rods 2, 3 in principle coincide with one another, so that the following description of the shaft rod 2 applies correspondingly to the shaft rod 3.
  • the shaft rod 2 has a rod body 8, which is essentially formed by a sheet metal part 9.
  • the sheet metal part 9 is for example in FIG. 9 separately illustrated. It may be a part made by roll forming. It has a constant cross section in the longitudinal direction. The longitudinal direction is in FIG. 2 horizontal and in FIG. 9 perpendicular to the drawing plane.
  • the sheet metal part 9 is provided with an upper edge 10 and a lower edge 11, which define a preferably completely, but at least largely flat central portion 12 between each other. The preferably uninterrupted, ie no essential openings having central portion 12 thus connects the upper edge 10 and the lower edge 11 in one piece and rigidly together.
  • the upper edge 10 is formed by a hollow profile, which is formed by bending the upper edge portion of the sheet metal part 9.
  • the hollow chamber may have a square rectangular, round or similar cross-section. It ends at a sheet metal leg 13, which is flat on a part of the central portion 12 and can be connected there by adhesive or by one or more welds with the central portion 12. Preferably, continuous welds are provided over the entire length of the edge 10 for connection. It may be laser welds.
  • the lower edge 11 is preferably formed by an angled region of the sheet metal part 9. He also carries a Litzentragschiene 14, which may be formed as a solid steel profile with a rectangular cross section, rounded at its narrow sides cross-section, L-section or similar cross-section. From the flat central portion 12, a leg 15 extends away, which is bent twice in each case by 90 °, but in opposite directions. It holds the heddle support rail 14 in a plane parallel to, but spaced from, the central portion 12. The leg 15 and the Litzentragschiene 14 are connected to each other, for example, by welding points or welds or a single longitudinally continuous weld. The heddle support rail 14 contributes to the stiffening of the rod body 8. While the heddle support rail 14 and the leg 15 thus together form the lower edge 11 of the rod body 8 and thus a lower stiffening means, the upper hollow chamber defined by the rim 10 forms a stiffening means 16 for the upper edge of the shaft body 8.
  • connection 17 To connect the side supports 4, 5, the shaft rod 2 with terminals 17, 18 is provided, the FIG. 2 can be seen.
  • the terminals 17, 18 are substantially equal to each other. The following description of the connection 17 thus applies correspondingly to the connection 18.
  • the sheet metal tab 19 preferably consists of a bent sheet metal strip with a flat portion 20 and an angled edge 21. This consists of a first leg 22 which extends in a first direction at right angles angled away from the portion 20, and a second leg 23, the is angled in a different direction at right angles to again extend parallel to the section 20.
  • This tin plate is like that FIGS. 2 and 3 show, placed on the sheet metal part 9.
  • the leg 23 is connected to the central portion 12 of the sheet metal part 9, for example by gluing or welding.
  • FIG. 11 explains the connection of the side support 5.
  • This may also be formed as a sheet metal bent part and carry at its end a corner piece 27.
  • the corner piece 27 may for example be mounted pivotably about a pivot axis 28 on the side support 5. It has a matching to the pocket 24 and cross section is inserted into this.
  • the corner piece 27 may be provided with a step 29, the edge of the sheet metal tab 19 on the Leg 22 engages behind. The leg 22 lies against the narrow side of the pocket 24 and the edge 10 opposite.
  • the edge 10 may be penetrated by a small opening through which a clamping screw 30 extends. This can be screwed into a threaded bore of a clamping piece 31, which sits in the area enclosed by the rim 10 hollow chamber.
  • the end of the clamping screw 30 protrudes into the pocket 24 and is supported on a narrow side of the corner piece 27. It presses the corner piece 27 against the leg 22 and thus secures it in the pocket 24.
  • the step 29 prevents forcible pulling out of the corner piece 27 out of the pocket 24, in particular if the clamping screw 30 is not completely tightened.
  • the Litzentragschiene 14 may also be part of the sheet metal part 8 by being formed as part of the lower edge 11.
  • the leg 15 is adjoined in this case by a leg 32 which is angled in the same direction, preferably at right angles, and which at its end can again have a narrow folded-back edge 33.
  • the upper edge 10 may be formed as described above.
  • FIG. 4 shows a sheet tab 34 may be provided as shown in FIG FIG. 6 is separately illustrated.
  • the section 20 is not only below but also above with a bent edge 35 is provided, which has two preferably at right angles to each other legs 36, 37.
  • the legs 23, 37 lie in a common plane.
  • the sheet metal tab 34 may be placed on the central portion 12 of the sheet metal part 9, wherein the legs 23, 37 are connected to the central portion 12.
  • welds or welds can serve.
  • rivets or the like may be provided.
  • a pocket 24 is formed, to which, as described above, a side support 5 can be connected.
  • the lower edge 11 may be formed exclusively by an attached sheet profile 38, as it FIG. 10 shows.
  • the set sheet profile 38 corresponds in shape, for example, in the lower edge 11 of FIG. 7 that is, it is formed U-shaped with unequal length legs, wherein the shorter leg is provided with a folded edge 33.
  • This sheet metal profile 38 may be made of the same material as the sheet metal part 9 or of another material, for example a harder steel. Preferably, it is a sheet metal part produced in the roll forming process. For connection, adhesive joints or welds or welds can be used. Preferably, at least one continuous over the entire length of the sheet metal profile 38 weld is provided to connect the flat superimposed parts of the longer leg of the sheet metal profile 38 and the lower part of the central portion 12 together.
  • the upper edge 10 can be modified as well FIG. 10 illustrated. This applies to all variants of the sheet metal parts described above and below 9.
  • the upper edge 10 may be formed by a U-shaped sheet metal section with two each perpendicular to the central part 12 in the same direction angled legs 40, 41, which enclose a unilaterally open interior.
  • a stiffening rod 42 may be used, which consists for example of a fiber composite material, for example a carbon fiber plastic composite material. This stiffening rod 42 may be secured by adhesive bonding to the surrounding surfaces.
  • stiffening rod 42 only on one side to the then completely flat sheet metal part 9 in this area.
  • the stiffening rod may be a rectangular profile, which is glued to a flat side with the sheet metal part.
  • the top edge 10 is then e.g. a straight extension of the middle part 12.
  • stiffening rod with a longitudinal slot into which the sheet metal part 9 extends.
  • stiffening rod 42 and the edge 10 or the sheet metal part can serve a glue joint.
  • the sheet metal part 9 is at its lower edge, similar to in FIG. 9 shown formed bent.
  • the heddle support rail 14 is here in contrast to FIG. 9 but not from a solid rail but from a sheet metal profile, which has been produced for example in the roll forming process.
  • Roll forming is also referred to as "roll forming”.
  • both the sheet metal tab 19 after FIG. 5 and the sheet metal tab 34 after FIG. 6 come into use.
  • all described shapes of the upper edge 10 may be combined with any described shapes of the lower edge 11 as desired.
  • metal tabs 19 and / or 34 may be disposed at other locations between the two ends of each shaft rod, for example, to connect center supports, shaft drives or other means.
  • the shaft rod according to the invention consists of only one (steel) plate, which is designed substantially without a large hollow chamber.
  • the sheet has two stiffeners, which are preferably at the top and bottom of the shaft rod and are formed as edges.
  • the upper stiffener 10 is realized by a small hollow chamber or a massive reinforcement.
  • the lower reinforcement 11 is realized by the connection of the heddle support rail.
  • the connection can be made by all known joining methods, such as welding, gluing, clinching.
  • the shaft rod can be made by bending or roll forming as well as by any other suitable for sheet metal forming process. It is preferred to integrate the heddle support rail directly into the sheet metal form of the shaft rod.
