Definitions

  • the invention relates to a guide rod for jacquard weaving equipment according to the features of the preamble of the claim 1.
  • Such guide rods also called selectors, are used in jacquard weaving facilities side by side and on top of each other in large Pieces used are, for example, in G 9112552.9, EP 0494044 A1 and SK 277761.
  • the Jaquard weaving facilities are specialized Device for weaving large patterned fabrics.
  • the Operation of the Jaquard weaving facilities is based on the fact that each warp thread can be raised or lowered individually, whereby the variety of patterns of the object to be woven there are practically no limits.
  • Jaquard weaving facilities become electronic modular devices with electromagnets used to control the lifting and lowering of the individual threads.
  • So-called slats are attached to the guide rods or boards moved up and down by knife bars.
  • To the Boards are attached to roller trains.
  • At the free ends of the Pulley cords are attached to harness cords.
  • harness cords are coupled to the individual warp threads. If the roller train is raised, it will be on this Roller tension lifted warp thread lifted.
  • a board must be held in its upper position become.
  • Jaquard weaving facilities are on one computer-controlled PC disk a variety of such Guide rods with integrated magnet systems for tightening of the jacquard slats.
  • Guide rods In a specific embodiment are 22 such guide rods next to each other arranged.
  • the boards themselves are also in a row arranged so that a jacquard weaving facility hundreds of has such guide rods.
  • the maximum packing density are due to the height of the guide rods Set limits. This is because in the guide rods each has a magnet system that is sufficient must be dimensioned large in order to be energized Coil arrangement of the magnet system for a safe magnetic Tighten the jacquard slats.
  • each two excitation coils arranged adjacent to one another are used, which are connected in series to each other. These two Excitation coils each sit on an iron core with a circular Cross-section.
  • the magnet system is completed by Cover the end faces of the two excitation coils with pole plates. This is sufficient when the excitation coils are energized generates high magnetic force to attract the Jaquard slats and the holding force is also sufficient this well-known magnet system had to be high have a sufficient axial height.
  • the number of turns of the for example, the two excitation coils was 1420 and it had to be energized with a current of about 115 mA to a To generate a holding force of 0.42 N.
  • the height of the magnet system that is, the axial length of the excitation coils or Iron cores were about 13 mm. The maximum packing density the guide rods to each other were thus predetermined.
  • the invention has the aim of the known guide rods of To further develop Jaquard weaving facilities so that they are one require less installation space and therefore an increased packing density can be achieved.
  • the guide rod according to the invention is essentially based on it, a cuboid elongated in cross section or at least approximately oval iron core as the carrier body to be provided for the excitation coil. At least this approximately oval or oblong, cuboid carrier body is a single excitation coil wound.
  • the iron core and the excitation coil has an axial height that allows that the on the opposite outer surfaces of the iron core with their ceiling walls are at a distance of ⁇ 13 mm from each other.
  • the new type of electromagnetic system integrated in the guide rods stands out in comparison to the previously known Electromagnetic systems with two excitation coils spaced from each other through a more optimal field distribution of the energized Electromagnetic system. This is essentially because that by using only a single oval excitation coil the field lines run evenly around the coil. With the two excitation coils at a distance according to the state of the art, however, it was the case that The space between these two coils is the field line forces have canceled each other, so that in the middle of the there is no or almost no magnetic force in both coils was.
  • the Iron core and the excitation coil wound on the iron core a total height of ⁇ 10 mm, preferably 7 or 8 mm have, so that the ceiling walls of the two End faces of the iron core and the excitation coil
  • the pole plates are also at a distance of ⁇ 10 mm. Due to the lower overall height of the entire electromagnetic system is ensured that compared to the previous known guide rods an increase in packing density of> 20%.
  • the Iron core is formed in one piece.
  • Such a one-piece Iron core which has an oval or elongated cuboid shape, can be worked from the solid, for example.
  • Another way to make one piece such an iron core consists in the sintering or in the novel MIM (Metal Injection Molding) technology.
  • iron core in several parts. This can happen, for example, in that two or more metal rod elements which are circular in cross section be lined up side by side. It can also be two Cuboids with one-sided rounding are strung together.
  • pole sheets Those on the opposite faces of the iron core or the excitation coil arranged pole sheets are preferred U-shaped in cross-section.
  • the pole sheets can by press, adhesive, rivet and / or welded connections be connected to the iron core.
  • the pole plate is preferred a stamped and bent part.
  • the pole plate made in one piece with the iron core.
  • a manufacturing method this is the MIM technology already mentioned above.
  • pole sheet and iron core can For example, take place in such a way that one of the pole plates together is made in one piece with the iron core and on a pole sheet in the free face of the iron core conventionally by punching, riveting, gluing or pressing is attached.
  • Another variant is that integrally on the two opposing pole plates a part of the iron core is formed and the both iron core parts then as free of air gaps as possible be joined together.
  • the pole plate thickness or pole plate thickness is approximately 1 mm.
  • FIG. 1 is a guide rod in different views 10 with its upper part in perspective Representation shown.
  • an electromagnetic system is integrated in the upper part of the Guide rod 10.
  • the known guide rod 10 according to FIG. 1 has the electromagnet system two to the longitudinal axis of the guide rod 10 spaced-apart iron cores 12, which are circular Cross section. Around these two iron cores is 12 one excitation coil 14 each wound.
  • the two excitation coils 14, each having approximately 1400 turns can be connected in series with each other and over Feed lines, not shown, can be connected to a power source.
  • the iron cores 12 with excitation coils wound over them 14 sit in a cavity of the guide rod 10 and thus between the two ceiling walls 10a and 10d and the two opposite side walls 10b and 10c.
  • pole plate 18 sits on each.
  • This pole plate 18 has via a ceiling wall 18a, which is riveted, welded, glued or press connection with the upper end faces of the iron cores 12 is fixedly connected.
  • the top wall 18a closes approximately flush with the top wall 10a of the guide rod 10 from.
  • a second pole plate 18 is on the opposite end faces the iron cores 12 are also arranged, but only shown in dashed lines in Figure 1. It should be noted in this context that in Figure 1, the guide rods 10 each cut in sections along its plane of symmetry are shown. The entire guide rod 10 is in his upper part with the integrated electromagnetic system in one of the representations of Figure 1 indicated by dashed lines.
  • jacquard slats or boards 16 lie on the two side walls 10b and 10c of the guide rod 10 jacquard slats or boards 16 on.
  • These jacquard slats 16 are at non-energized electromagnetic system, that is, not of electricity flowed excitation coils 14, spaced with an air gap L. to the side walls 18b and 18c of the pole plates 18. If, on the other hand, current flows through the excitation coils 14, a magnetic field builds up through which the jacquard lamellas 16 to the side walls 18b and 18c of the pole plates 18 get dressed by.
  • the overall height of the known guide rods 10 is due to the axial extension of the iron cores 12 and the wound around them Excitation coils 14 together with attached pole plates 18.
  • the overall height of the previously known guide rods 10 about 13 mm.
  • FIGs 2 and 3 is a perspective view shown an iron core system as it is in the guide rods 14th is used according to the invention. It is one now Iron core 12 is provided, which is elongated or oval in shape Cross section is formed. Around the circumferential surface of this elongated or oval-shaped iron core 12 is the excitation coil 14 wound, which consequently also has an oval contour. On the two end faces of the iron core 12 or the excitation coil 14 sits on a pole plate 18, of which in FIG 3 only the upper pole plate 18 is shown.
  • iron core 12 in one piece can be formed, it is within the scope of the invention to design iron core 12 in several parts, for example two parts. This is indicated in Figure 2 above. There are each in cross section circular iron bar parts next to each other lined up. In addition to such strung together iron core parts 12a, it is also possible for a large number of iron wires is packed together so that the one shown in FIG. elongated or oval cross-sectional shape of the iron core 12 is coming.
