Definitions

  • the invention relates to a single-set terry jacquard machine with a double-hat open-box method of operation and with a roller train, according to the preamble of claim 1.
  • the basic structure of jacquard machines suitable for the production of terry goods is generally known. Loops are characteristic of terry goods. The interaction of pile warp threads and basic warp threads is necessary for their production. The use of jacquard machines in such terry towels allows the additional weaving of borders.
  • an adjustable terry jacquard machine is known, one part of which for the pile warp threads and the other part for the base warp threads. is seen.
  • Such a jacquard machine differs from a conventional jacquard machine, apart from its size, generally only in that the characteristic floors such as harness guide floor and choir floor are formed in one piece and the guide openings for the pole harness cords assigned to the pile warp threads and that for the basic warp threads assigned basic harness cords have some distance from each other.
  • jacquard machines with a double open compartment method and with a roller pull one end of a harness cord is also fixed at a fixed point, for which there are different designs.
  • the other about one The end of the roller train is guided through the openings in the guide floor and choir floor and connected to the associated warp thread.
  • each harness cord to be fixed is fixed, for example, to a grid or to bars fastened in the frame of the machine. It is also possible to set this end yourself in the harness guide floor. These designs are conventional.
  • a disadvantage of such an adjustment arrangement is that adjustment work, as is generally required with weaving machines, is quite difficult and only possible to a limited extent.
  • An essential adjustment is the height adjustment to set a favorable specialist position within the machine. This is usually done in the factory according to the specifications of the client and must therefore be observed for each individual case.
  • the invention is based on the basic consideration that this can only be achieved in that an adjustability in operation, as with the individual machines, must be guaranteed.
  • the invention is further developed by the features of the subclaims.
  • two structural designs are basically suitable for realizing the height nighttime adjustment according to the invention.
  • a frame fastened in the frame for each or for both floor arrangements the one or both floor arrangements are each supported for height adjustment, for example via a screw spindle arrangement.
  • a frame can be provided for each of the floor arrangements, in which the floor arrangement is fastened. Then the respective frame is attached to the machine frame in a height-adjustable manner, for example by means of a screw spindle arrangement.
  • the jacquard machine for producing terry goods is designed in a single common frame as a single-position terry jacquard machine, in which a pile chain section P on the weaver stand side (or front) and a base chain section G is provided.
  • the pile warp threads P K of the pile chain section P and the base warp threads G K of the base chain section G are subjected to the control of the jacquard machine via respective harness cords 1 and 2.
  • the harness cords 1 and 2 are deflected through openings in a harness floor arrangement 3 via a roller train 4 and are fixed at the other end in a floor arrangement, which is explained in more detail below, in the frame of the jacquard machine, not shown, as is shown schematically by black dots.
  • the harness cord 1, 2 is made in two parts, the two ends above the harness guide floor arrangement 3 being connected to one another in a fixed but detachable manner by means of a connection device 5 which is conventional per se.
  • the control C which is customary for jacquard machines of this type can be of a conventional type. It is therefore only shown schematically in such a way that two sinkers 6 and 7 are connected to one another via a sinker cord 8 running over another roller of the roller train 4. Furthermore, this board cord 8 passes through a board bottom.
  • the boards 6 and 7 are moved up and down by means of conventional devices between an upper and a lower specialist position and controlled by conventional devices and, if necessary, are held in one of these specialist positions depending on the pattern to be achieved. Mechanical or electromagnetic devices are customary for this.
  • a disadvantage of such jacquard machines is that elongation of the harness cords 1, 2 occurs during long operation, the basic harness cords 2 becoming longer than the pole harness cords 1 due to the given loads the given setting of the jacquard machine achievable quality no longer achievable.
  • Readjustment is, however, only possible to an extremely small extent, whereby influence on the adjustment of the various floors to one another, which was previously carried out at the factory alone, in particular the harness guide floor arrangement relative to the others or the frame, can be influenced, but this influence both on the pole chain section and also Basic chain section is done uniformly and is only possible to a very small extent.
  • the fixed points 9 for the pole chain section P and / or the fixed points 10 for the basic chain section G are designed to be height-adjustable in the frame, provided that both the pole fixed points 9 are the basic fixed points 10 are also adjustable, independently of one another.
  • both the P fixed points 9 and the G fixed points 10 in the frame can be adjusted in height.
  • both the harness guides that is to say openings 13 and 14, and the fixed points 9 and 10 are provided in a single plate 11 and 12, respectively.
  • a solid position is shown in full lines, with respect to which each plate 11 or 12 can be individually adjusted in height.
  • the base fixed points 10 in the base chain section G can be adjusted in their position relative to the pole fixed points 9 in the cup section P, in such a way that the shed formation achieved by the pile warp threads P K on the one hand and the base warp threads G K on the other hand can again be adjusted to the desired optimal case.
  • Fig. 2 shows an embodiment in which the base plate 12 is adjustable in height from front to back, in particular in the case of a plate-like design, it is adjustable in angle. In this way it can be taken into account that the load on the basic harness cords 2 can vary from front to back. In this way, adjustability is achieved within the scope of the triangular hatched area 16 shown at the bottom right in FIG. 2. It is further assumed that in the embodiment according to FIG. 2, adjustability for the pole harness cords 1 is not necessary.
  • this additional adjustability can also be provided and the height adjustability in one plane for the base plate 12, as has also been explained with reference to FIG. 1, can also be provided .
  • the plates 11 and 12 form both a floor for the fixed points 9 and 10 and the harness guide floor with the openings 13 and 14, respectively.
  • the invention is not limited to such designs of the harness guide floor arrangement 3. Rather, as explained with reference to FIG. 8, it is only essential that the fixed points 18 of a fixed point floor arrangement 19 can be adjusted in height at least for the basic chain section G, expediently also for the pole chain section P, but then separately from one another, while the guide openings 20 for the harness cords 1 , 2 having harness guide bottom 21 for basic chain section G and pole chain section P can be common and can be fixed in the frame in the usual way.
  • any conventionally known construction can be used for the respective fixed point floor section 19, such as a grid or grate arrangement, a rod arrangement or the like.
  • the plates 11 and 12 are held in separate frames 23 and 24, respectively.
  • These two holding frames 23 and 24 can be individually adjusted with respect to a common frame 26 by means of adjusting devices 25 distributed over the circumference, the common frame 26 being fastened to the machine frame by means of supports 27 designed as flat irons.
  • the adjusting device 25 in the exemplary embodiment according to FIG. 4 has a support and guide element 28 and a screw spindle 29 which enables the height adjustment.
  • the respective frame 23 or 24 can be adjusted relative to the common frame 26 from a lower position to an upper position, the support and guide element 28 also ensuring lateral guidance.
  • the respective position is secured, for example by means of lock nuts and / or fixing screws 30.
  • the plate 11 or 12 is fixed in a frame 32 via clamping and fixing elements, namely horizontal and vertical screw bolts 33 and 34, respectively.
  • the frame 32 is in turn arranged in a support frame 35 with a C cross section.
  • the horizontal screw bolts 33 are led out through elongated holes 36, the elongated holes 36 permitting height adjustment.
  • An upper screw bolt 37 and a lower screw bolt 38 with respective lock nuts 39 and 40 allow the position of the frame 32 and thus the plate 11 and 12 relative to the support frame 35, which in turn is fastened in the machine frame like the common frame 26.
  • the adjustment bolt on the adjustment direction is first loosened and unscrewed from the support frame 35 to the required extent, and then the associated lock nut is adjusted to fix this bolt. Then the lock nut of the other screw bolt is loosened and the associated screw bolt rotated until the support frame 32 is clamped again between the two screw bolts. Then the lock nut is adjusted.
  • Fig. 6 shows schematically an arrangement in which each plate 11 or 12 can be adjusted in height by the fact that the respective frame 42 or 43 is attached to the frame 46 for its height adjustable on the support arms 44 and 45 respectively is.
  • a screw adjustment device 47 or 48 is assigned to each support arm 44, 45, wherein the screw adjustment arrangements can have the same design.
  • a threaded rod 49 is fixed on the frame 46, for example via nuts and lock nuts, and a bracket part 50 connected to the respective support arm 44, 45 can be guided along this threaded rod 49 and by means of an upper lock nut 51 and a lower lock nut 52 definable and if necessary. additionally fixable by a fixing screw 53.
  • each support arm 44, 45 is guided on the bolt 46 on the frame 46 via elongated holes 54.
  • the height adjustment can also be done in a different way, for example hydraulically.
  • the representation according to FIG. 6 is schematic and in practice the height adjustment arrangements are fixed in the machine frame 46 relative to the respective frame 42 or 43 in such a way that the distance between the pole chain section P and the basic chain section G is as small as possible, for example in that these arrangements are pivoted through 90 ° with respect to the plane of the drawing.
  • the design according to the invention of a single-set terry jacquard machine allows continuous adjustment of the fixed points 10 of the basic chain section G on the one hand and / or the fixed points 9 of the pole chain section P on the other hand in continuous operation with only minor interruptions, possibly even during operation, to take account of those occurring during continuous operation Lengthening of the respective harness cords 2 or 1 to ensure high quality of the terry goods to be manufactured over long operating times. Nevertheless, the advantages inherent in a single-terry jacquard machine are retained.
  • the effect achieved by the invention can be achieved by means of a comparatively small change in the construction, the costs of which are of secondary importance compared to the total costs of the machine.
