Definitions

  • the invention relates to a rotary edge turner for weaving machines, by means of which the weft threads are tied at the fabric edges by means of a leno weave.
  • the drive of the edge turner arranged on both sides of the weaving machine next to the edge warp threads takes place in such a way that the rotary disc forming the actual edge rotator is connected to a drive wheel in a rotationally driven connection via a toothed belt.
  • the drive wheel is non-rotatably connected to and driven by a gear-driven countershaft.
  • the countershaft is in turn connected to the main drive of the weaving machine by a toothed belt.
  • the countershaft is connected to a hollow shaft protruding in the direction of the weaving width adjustment, in which a shaft part which drives the second rotator disk and the drive of the second rotator bobbin holder can be displaced.
  • Such a drive is expensive, not space-saving, not independent of the main drive and cannot be controlled individually.
  • the rotating disc has external teeth. Furthermore, the rotating disc is rotatably mounted in a bezel-like manner. The leno threads are drawn off from a bobbin winder, which is rotationally driven and operatively connected to the rotating disc, and fed to a guide opening located centrally in the rotating disc.
  • the rotating disc also has two diametrically opposed eyelets in the rotating disc, through which the thread is guided to the weaving point of the fabric.
  • the external toothing of the rotating disc is in engagement with the teeth of a drive gear which drives the rotating coil holder in synchronism with the rotating disc.
  • edge turner In contrast to the prior art, the edge turner should not be separated from the weaving machine for the purpose of changing articles, and the edge turner should be readily adaptable to different weaving widths. This is intended to achieve considerable savings in makeready times in the weaving mills.
  • Another object of the invention is to dispense with a separate drive for the holder (carousel) receiving the leno thread bobbins.
  • a separate drive for the holder (carousel) receiving the leno thread bobbins According to the prior art, such a drive is intended to prevent the leno threads from looping around one another in the area of the back pocket. In order to avoid thread breaks, the leno threads must be fed to the rotating disc without twisting.
  • the solution according to the invention is also intended to enable conventional leno coils, so-called king coils, to continue to be used. This guarantees long machine running times, in contrast to the use of satellite rotator coils.
  • the electromotive actuator it is now possible for the first time to control the sequence of movements of the individual edge twists independently of one another and independently of the weaving machine drive. It is conceivable, for example, that the setting of the weft threads can take place depending on the type of the weft thread and that the setting of the weft thread on the side of the weft thread insertion is before the setting of the weft thread on the weft thread arrival side.
  • a controlled reversal of the direction of rotation of the rotating disc which ultimately also includes an oscillating reversal of the direction of rotation, means that there is no need to drive the rotating bobbin holder, because in any case the twists or loops of the leno threads on the way between the rotating bobbins and the rotating disc, caused by a specific one Number of right turns of the rotator disc can be canceled by the same number of left turns of the same rotator disc.
  • a self-contained edge-turning device can also be created, which can be attached individually within the weaving machine and whose functional elements are largely shielded from the fiber fly.
  • this edge turner can be installed as close as possible to the weaving point and between the shaft frame and the healds of the first heald frames, as seen in the opposite direction to the weaving direction, according to the reed. This means that the number of usable heald frames in the direction of the warp beam is not limited by edge turning devices.
  • edge turner Due to the compact design of the edge turner, it is possible to position the edge turner quickly on the changed conditions on the weaving machine in the event of an article change or a weave width adjustment.
  • the rotary edge turner exists according to 1 from a support arm 2 which, for example according to FIG. 2, forms a housing with a clamping part 2a for positive connection to a component 3 of the weaving machine, which component 3 is connected to component 4 and the component 4 with means for adjusting the weaving width communicates.
  • a drive wheel 5 for example a toothed wheel, is partially wrapped around by a drive belt 6, for example a toothed belt, and is guided on a rotating disk 7.
  • the drive wheel 5 is non-rotatably connected to the armature shaft of an electromotive actuator 20.
  • the support arm 2 forms a three-point bezel bearing with the bearing rollers 8, 9, 10 at one end.
  • the rotating disk 7 is designed, for example, in the manner of a toothed ring and has external teeth (not shown) with which the teeth of the drive belt 6 mesh.
  • the bearing rollers 8,9,10 are rotatably mounted on axes 8a, 9a, 10a. These axes are attached to three points spaced apart from one another on the support arm 2 such that they form the three-point steady rest.
  • the bearing rollers 8, 9, 10 act on one side of the drive belt 6 wrapping around the rotating disk 7 and center the rotating disk 7 in the process.
  • the rotating disc 7 has two slots 7b, 7c, which are arranged symmetrically to the center axis 7a of the rotating disc 7 and are designed in the form of a circular arc.
  • a leno thread 11, 12 supplied by the leno thread bobbins 21, 22 (FIG. 3) is passed through each slot 7b, 7c.
  • rotary edge-turning device shown here is an edge-turning device arranged on the left-hand side of the weaving machine
  • a further edge-turning device is arranged on the right-hand weaving machine side.
  • Both rotary edge rotators are arranged in the area of the free space between the shaft frame, not shown here, and the strands of the first heald frames, which, seen in the weaving direction 30, are located in front of the reed 18.
  • a left-hand rotary edge rotator 1 is also connected to the component 3 via the clamping part 2a by means of a machine element 16.
  • the support arm 2 is designed here as a housing that can be closed with a cover.
  • the weaving machine is merely represented by a sley in the rear end position and a sley 17 in the front weft stop position with reed 18 and an auxiliary blowing nozzle 19 arranged on the sley 17.
  • the axis 21a of the roller 21 tensioning the drive belt 6 is received within a longitudinal guide 22 provided in the housing wall.
  • the belt tension of the drive belt 6 can be adjusted by displacing the roller axis 21a in the longitudinal guide 22.
  • an electrically controllable servomotor 20 as a drive for the rotating disc 7 of the rotary edge rotator 1 allows the weaving machine manufacturer to dispense with a separate rotary drive for the leno thread bobbins 21, 22, because, for example, by programming a number of Rotations of the servomotor 20 and thus by a fixed number of revolutions of the rotary disc 7 in one direction and by the same number of revolutions in the opposite direction, a looping of the leno threads 11, 12 supplied by the rotator bobbins 21, 22 no longer occurs in the rear compartment .
  • a servomotor 20 as a drive for the rotary disk 7 also allows the direction of rotation of the rotary disk 7 to drive weft for weft reversibly. In this case too, a separate drive for the rotating coils 21, 22 is not required.
  • a first leno thread spool 31 is rotatably mounted axially parallel to a second leno thread spool 32 within the rim of the edge rotator 1 forming the rotating disc 7.
  • the bearing of the leno thread bobbin 31, 32 is designed in such a way that a certain self-braking effect takes effect when the leno thread is withdrawn, i.e. the leno thread bobbins 31, 32 are not freely rotating. It is thus possible to pull the leno threads 11, 12, which are passed through the eyelets 7b, 7c, from the leno bobbins 31, 32 in the direction of tissue formation 30 as required.
  • weft threads 15 on the fabric edge 23 in the direction of the goods take-off see also arrow direction 26, from the weaving machine through the leno threads 11, 12 as a single weave (each end of the weft thread 15 is tied) and as Misfiring (after two or three weft entries, the end of the weft thread 15 is tied).
  • FIG. 6 shows another advantageous application variant which the servomotor-operated rotary edge driver offers.
  • the course of movement 27 of the shedding device is shown with a full rotation of the main loom shaft with shutting down 27a.
  • the intersection points 24 and 25 represent the shed after the entry of a first weft 15 and before the entry of a second weft 15 into the open shed.
  • the selvedge 1 In order to guarantee a correct entry of the weft thread 15 also in the shed of the leno threads 11, 12 and to be able to tie the ends of the inserted weft thread 15 by means of the selvedge 1, it is necessary that the selvedge 1 has a movement path 28 of the leno shed that is adequate for the shed formation guaranteed. This is made possible by a corresponding speed control of the rotary disc 7 by means of the servomotor 20.
  • the course of motion 28 of the leno pocket is shown in the course of movement 27 of the shedding device. During the shutdown 27a, the leno compartment reaches its largest opening. The course of movement 27 coincides in points 29 with the course of movement 28. This point in time represents the optimum for the weft insertion of the weft thread 15 and its guaranteed binding by the leno threads 11, 12.
