Definitions
- the invention relates to a shaft which is to be used in particular on weaving machines.
- shafts on which several strands are held which guide the warp threads are known for example from DE 196 07 532 AI.
- the shaft has an upper and a lower shaft rod oriented transversely to the direction of movement of the shaft, the two shaft rods held parallel and at a distance from one another being connected at their ends via so-called side supports
- a frame which is approximately rectangular in front view is thereby formed.
- a heddle support rail is fastened to both the upper shaft rod and the lower shaft rod. Between the heald support rails, healds are held, each of which hangs on the support rail with their end loops.
- Each strand has a thread eye or eye for a warp thread.
- the heddle support rails are provided with tabs that establish the connection to the shaft rods.
- Each tab connected to the heddle support rail is assigned a socket arranged on the shaft rod.
- Coupling devices each serve for the positive connection between each socket and the respectively assigned tab.
- the shaft rods each have two flat sides and a narrow side arranged between them, which faces the heddle support rail.
- the sockets are screwed onto this narrow side by means of bolts.
- the coupling device is formed in a first embodiment by a rectangular bolt which is pushed parallel to the heddle support rail through openings in the socket and the tab.
- the socket has an eyelet, in which the tab is hooked like a hook. In both execution forms, the connection between the tab and the socket has a certain amount of play. This type of mounting of the heddle support rail on the shaft rod limits the speed range in which the shaft can be used.
- the entire heald frame must be replaced if the heddle support rail wears out.
- the mounting rails can wear out after a relatively short period of use.
- the longitudinally continuous leg contributes to the weight of the shaft, which is noticeable during rapid shaft movements.
- the utility model 1 799 695 also provides a fixed connection between the shaft rod and the heddle support rail.
- tabs are used, which are riveted at one end to the heddle support rail and at the other end to the shaft rod. If the heddle support rails are worn out, the entire heald frame must be replaced.
- a shaft for a weaving machine is known from JP 59-149982, in which the shaft rod is formed by a rectangular hollow profile. Its wall facing the heddle support rail is designed to be thickened, so that spaced-apart holders can be let into this wall and can be positively anchored in it with a thickened head. The holders are angled at the bottom and have threaded holes. The stranded support rail is screwed to the brackets here.
- a shaft is known from CH 331414, the shaft rods of which each have a web to be extended onto the heddle support rail. Fastening bolts are embedded in this web, to which the connecting lugs for the rail can be screwed.
- the connecting straps have elongated holes to enable tolerance compensation.
- the shaft according to the invention has between its heddle support rail and its shaft rod at least two connecting devices which are laterally spaced apart and each connect the heddle support rail to the shaft rod.
- the connecting devices are separate parts separated from the shaft rod, which are integrally connected to the shaft rod.
- the connection is preferably exclusively cohesive, ie without the support of a positive engagement or the like. The wall and any inlays of the shaft rod remain unharmed.
- the integral connection is furthermore preferably purely superficial and at least linear, but preferably flat. As a result, force is introduced into the outer skin of the shaft rod, without this having to have openings or openings.
- the connection is thus preferably made on a closed surface of the Shaft rod.
- the shaft rod can be made of fiber-reinforced plastic, for example carbon-fiber-reinforced plastic or glass-fiber-reinforced plastic, in order to combine high strength with low weight.
- the shaft rod is mechanically connected to the interchangeable heald support rail by means of lugs, the lugs forming the connection element or belonging to one. In the first case they are directly connected to the shaft rod in a direct manner and in the second case indirectly via a socket.
- This principle can also be used if the shaft rod is a lightweight construction constructed in another way.
- it can be formed by a metal honeycomb structure.
- Such is formed, for example, by two sheets (preferably steel sheets) arranged at a distance from one another, between which honeycomb formed from thin sheet metal or from plastic-reinforced paper, e.g. Hexagonal honeycombs. At the upper and lower ends, the gap between the two sheets can be closed by plastic elements.
- the connecting device preferably overlaps the shaft rod on both sides, so that two leg-like extensions receive the shaft rod between them and rest on its flat sides.
- the connection can be made here, for example, by surface bonding or by laser welds.
- the laser weld seams can be guided along the edge of the extension like a hem. You can also run over the surface of the extension.
- the connection here is limited to one or more strip-shaped areas. However, this is sufficient for power transmission even if the shaft rod is an extremely lightweight metal construction (constructions with foamed spaces).
- the welded connection can be made by laser or electron beam can be produced. If the shaft rod is made of fiber-reinforced plastic, the connecting device is glued or laminated or glued into the fiber-reinforced plastic body without damaging fibers, which guarantees its strength.
- the connecting device can also be embedded in the shaft rod and thus glued to it. This also ensures good power transmission.
- the connection between the connecting device and the shaft rod is also preferably carried out only by material connection and not by positive connection, in order to achieve the most extensive possible introduction of force.
- the connecting device is preferably formed at least in two parts, so that it is divided into a tab and a holder which are detachably connected to one another.
- a coupling means is effective, which is preferably designed to be free of play.
- the socket has, for example, two legs which define a receiving space for a coupling section of the tab between them.
- a clamping device for clamping the coupling section can be assigned to the legs, as a result of which this is held in the coupling position without play.
- Such connections enable the transmission of the forces occurring at high working speeds and thus high accelerations.
- the fixed and play-free connection between the heddle support rail and the shaft rod which results from this, enables high machine speeds.
- the coupling device positively defines the coupling position.
- the positive position determination preferably does not affect the longitudinal position of the heddle support rail. This can be achieved by forming a rib on the socket as a form-locking element, which extends parallel to the shaft rod and which is assigned a groove formed in the coupling section. Alternatively, a groove can also be provided on the socket and a corresponding rib can also be provided on the coupling section of the tab. A certain amount of longitudinal play is possible in both cases, which makes replacing the heddle support rail easy. It is only necessary to insert the coupling sections of the tabs into the corresponding sockets, after which the clamping means provided on the sockets are to be tightened.
- the connecting device can be made entirely or partially of plastic.
- the socket and / or the tab can be made of plastic. This dampens and changes vibrations that are generated by the strands on the strand support rail. These vibrations are therefore not fully transmitted to the shaft rod by the plastic and thus reduce its load.
- the measure also has a noise-reducing effect.
- FIG. 1 shows a shaft for a weaving machine in a schematic front view
- FIG. 2 shows the shaft according to FIG. 1 in a cutaway and cut perspective view
- Figure 3 shows the shaft rod of Figure 2 in another
- Figure 4 shows the shaft rod and the heddle support rail
- a shaft 1 is illustrated in FIG. 1, which has an upper shaft rod 2, which is generally arranged horizontally, and a shaft rod 3 held parallel to it at a distance.
- the shaft rods 2, 3 are connected to one another at their ends via side supports 4, 5, so that these form a rectangular frame together with the shaft rods 2, 3.
- a plurality of strands 6 arranged parallel to one another are arranged in this, each of which is provided with a thread eye 7 for guiding a warp thread.
- the strands 6 arranged parallel to the side supports 4, 5 each have an end wire at their upper and lower ends with which they are held on a strand support rail 8, 9.
- the heddle support rails 8, 9 extend parallel to the respective adjacent shaft rods 2, 3 and are held at a distance from them.
- the shaft rod 2 is designed as a lightweight profile.
- This includes two flat bodies, for example in the form of sheets 15, 16, for example made of stainless steel, which are kept parallel to one another at a distance and which form the flat sides of the shaft rod 2.
- Spacers for example in the form of a honeycomb arrangement 17, are provided between the sheets 15, 16, which are glued or otherwise connected to the sheets 15, 16.
- a plastic body 18, 19 with a rectangular or square profile can be glued.
- connection device 11 which is also shown in particular in FIG. 3, includes a socket 21 and a tab 22 which are connected to one another by a coupling device 23.
- the socket 21 is either in one piece or, as can be seen in FIGS. 3 and 4, in two pieces by having a first socket element 24 and a second socket element 25, both of which are each formed by a flat leg. Each leg has a flat section lying on the sheet 15 or 16, which forms an anchoring section 26, 27.
- the socket elements 24, 25, which together form the socket 21, are constructed symmetrically to one another.
- their anchoring sections 26, 27 are glued flat to the sheet metal 15 and 16, respectively.
- the adhesive is in each case in the joint between the anchoring section 26 and the sheet 15 or in the joint between the anchoring section 27 and the sheet 16. It serves for the integral connection and for the transmission of longitudinal forces, which are shown in FIG. 4 in the plane of the drawing lying vertically.
- each leg 28, 29 of the socket elements 24, 25 protrude beyond the lower narrow side of the shaft rod 2.
- the legs 28, 29 can spring slightly towards and away from each other, a possible spring stroke of a few tenths of a millimeter being completely sufficient here.
- the legs 28, 29 form one Half of the coupling device 23, which serves to connect the tab 22.
- the legs 28, 29 have web-like ribs 31, 32 on their mutually facing sides, which for example have a rectangular cross section and extend parallel to the longitudinal direction of the shaft rod 2, ie perpendicular to the plane of the drawing in FIG. 4. They are also aligned parallel to one another and enclose a distance from one another and towards the shaft rod 2.
- the ribs 31, 32 are firmly connected to the legs 28, 29, for example by rivets or welded connections. Their cross section can also be trapezoidal or otherwise fixed.
- the tab 22 is provided with a coupling section 33, which forms the other half of the coupling device 23.
- the coupling section 33 has a rectangular basic profile, which is provided on both opposite flat sides with grooves which fit exactly with the ribs 31, 32.
- the coupling section 33 thus has an I-shaped or H-shaped cross section, which fits with little play between the legs 28, 29. He can thus in the longitudinal direction of the ribs, i.e. in Figure 4 are inserted perpendicular to the plane of the drawing between the legs 28, 29 in order to first establish a positive connection between the tab 22 and the socket 21.
- dashed bolts 34, 35 (see Figures 2, 3), which reach through both the legs 28, 29 and the coupling section 33.
- the fastening bolts 34, 35 are seated in bores or threaded bores, which preferably pass through the ribs 31, 32.
- the rib 31 is preferably made somewhat thicker than the rib 32. A sufficient height for forming a threaded bore is thereby achieved.
- the fastening bolts 34, 35 form clamping means in order to clamp the legs 28, 29 against one another and thus against the coupling section 33 and to clamp the latter without play.
- a flat section of the tab 22 preferably extends off-center, ie approximately in the plane of the sheet 16. This section, like the entire remaining tab 22, can be made of plastic or of light metal, for example aluminum.
- the tab is provided with a projection 36 which points towards a plane defined by the sheet 15.
- the projection 36 serves as an abutment for the heddle support rail 8, which is designed as a flat profile with rounded edges.
- the projection and the heddle support rail are provided with aligned openings into which a rivet 37 is inserted for a firm connection. As illustrated in FIGS. 2 and 3, further rivets 38, 39 can be provided.
- the heddle support rails 8, 9 are held firmly on the shaft rods 2, 3 via the connecting devices 11, 12, 13, 14.
- the sockets 21 are glued to the shaft rods 2, 3.
- the tabs 22 are positively and non-positively clamped between the legs 28, 29 by the coupling devices 23.
- the introduction of forces from the strand support rail 8 occurs superficially in the surface 15, 16. Die. inner structure of the shaft rods 2, 3 is not affected.
- the heddle support rail 8 shows signs of wear. It can be exchanged in the simplest way by loosening the coupling device 23 by removing the fastening bolts 34, 35. The heddle support rail 8 can now be uncoupled by moving it somewhat in the longitudinal direction. The coupling section 33 slides out of the space enclosed by the legs 28, 29 and is thus released. A new heddle support rail with new brackets 22 is inserted in the opposite way and tightened again. With this shaft, the heddle support rails 8, 9 can be replaced if necessary. The shaft rods 2, 3 are not affected. They can therefore also be made from expensive lightweight materials if necessary.
- the anchoring sections 26, 27 of the socket elements 24, 25 are not welded by gluing but by welds S. Sheets 15, 16 attached.
- the weld seams can be guided along the outer edge of the anchoring sections 26, 27. They can also be guided in the form of one or more lines L parallel to one another over the surfaces of the anchoring sections 26, 27.
- FIG. 5 A modified embodiment of the shaft is illustrated in FIG. 5 with the aid of its shaft rod 2 and the heddle support rail 8.
- the previous description applies in full to shaft rod 2 and version 21.
- the fastening bolts 34, 35 are not shown.
- the tab 22 is made of plastic.
- the heddle support rail 8 can be fastened to this by means of a weld seam 42 or a series of individual welding spots.
- FIG. 6 A further modified embodiment is illustrated in FIG. 6. Unless differences are expressly explained below, the description given for FIGS. 1 to 4 applies accordingly, using the same reference numerals.
- the tab 22 is formed by a cranked steel band, which is connected at its lower end to the heddle support rail 8 via a weld 43. As shown, the weld seam can be produced starting from the tab 22 or, if necessary, also starting from the heddle support rail 8.
- the cranking fung of the tab 22 creates the necessary space between the heddle support rail 8 and the tab for receiving the end loops of the strands.
- the tab is provided with holes 44 for the fastening bolts 34, 35.
- the thickness of the tab 22 corresponds to the distance between the ribs 31, 32 from one another. It is clamped non-positively between the ribs 31, 32.
- a positive connection as is achieved by the part of the coupling section 33 that overlaps the ribs 31, 32 above and below, has been dispensed with here. Nevertheless, the upper end of the tab 22 forms a coupling section 33.
- FIG. 1 A further modified embodiment is illustrated in FIG.
- the special feature here is that the connecting device 11 is formed in one piece, i.e. is not divided into socket and tab. Rather, a forked section 45 is molded onto the actual tab 22, which is preferably made of plastic, the two legs 46, 47 of which overlap the shaft rod 2 on its flat sides. The legs 46, 47 are thus in contact with the sheets 15, 16 and are glued here to the surface.
- the heddle support rail 8 is in turn attached to the lower end of the tab 22.
- a screw 48 with a countersunk head is preferably provided instead of the rivet 37, which is fastened in a threaded bore with a metal wall and / or in a threaded bore in a metal insert 49 of the connecting device 11 , Even then, an adhesive connection to the sheets 15, 16 can be produced. Alternatively, a welded connection is possible.
- FIG. 8 illustrates a further modified embodiment of the invention. While a symmetrical introduction of force into the sheets 15 and 16 took place in all the embodiments discussed above, the introduction of force in the embodiment according to FIG. 8 is asymmetrical.
- the connecting device 11, which is formed, for example, by a plastic or metal element, has only one leg 47 which is connected to the shaft rod 2, which here consists of a fiber composite material is glued.
- the tab 22 can be provided with a projection 51 which overlaps the lower narrow side of the shaft rod 2 and which bears with an upper contact surface on the lower narrow side of the shaft rod 2 and is glued to it here. Otherwise, the description given for FIG. 7 applies accordingly.
- the shaft rod 2 as in the embodiment according to FIG. 8, is formed by a fiber composite material. It can be a hollow profile or an internally foamed profile.
- an upwardly extending sword-like extension 52 can be formed on its projection 51, which is embedded in the plastic material of the shaft rod 2.
- the extension 52 is preferably delimited with parallel flanks and has no undercuts. It is laminated into the shaft rod 2.
- Legs 46 and / or 47, as shown in FIG. 7 or 8, can additionally be provided.
- Several projections 52 can also extend upward from the projection 51, which are aligned parallel to one another or at an acute angle to one another.
- Brackets are provided for the detachable attachment of heald support rails 8 to shaft rods 2 of a shaft 1 of a weaving machine, which in a preferred embodiment essentially consist of two sheets, part of which forms an adhesive surface for connection to the shaft rod 2.
- the part that remains free, ie the free longitudinal edge of the sheets, is used to hold one metallic reinforcing strip (rib 31, 32), which can be riveted or welded to the sheet.
- rib 31, 32 metallic reinforcing strip
- These reinforcement strips serve on the one hand to accommodate fastening elements for a tab and on the other hand to position this tab. The positioning is thus achieved in a form-fitting manner.
- the sheets are preferably clamped against the tab by means of screws in order to clamp them in the positively fixed position.
- rivets can also be used, which can be used with simple tools can be solved for example by expressing.
- the reinforcement strips are designed and fastened to the metal sheets in such a way that the reinforcement also serves for the exact positioning of the tab 22 in order to positively prevent a vertical displacement of the tab during the operation of the heald frame.
