Definitions

  • the invention relates to a rotary edge turner for weaving machines, by means of which the wefts through a twist tie be tied at the fabric edges.
  • This arrangement consists of a rotationally driven rotary disc, the geometric center axis of which is parallel to the weft direction of the weaving machine and the rotary disc is driven at the same speed as the bobbin holder carrying the rotary bobbins.
  • the rotating disc has two slots for the leno threads arranged symmetrically to its central axis.
  • 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.
  • a shaft part which drives the second rotator disk and the drive of the second rotator bobbin holder can be displaced.
  • 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 loops arranged 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.
  • the edge turner should Not separated from the weaving machine for the purpose of changing articles and the edge turner should easily be sent to different Web widths are customizable. This is said to be significant Saving of makeready times can be achieved in the weaving mills.
  • the rotary edge turner should also be a simple constructive Own structure and direct, i.e. without inclusion a transmission medium between the servomotor and the Rotary disc, be drivable.
  • the object is achieved by the features of claim 1.
  • 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 can be before the setting of the weft thread on the weft thread arrival side.
  • This edge turner can advantageously be positioned as close as possible to the weaving point of the fabric and between the frame and the healds of the first heald frames.
  • the number of usable heald frames in the direction of the warp beam, ie opposite to the weaving direction, is thus not limited.
  • edge turner Due to the compact design of the edge turner is in the case an article change or a web width adjustment rapid positioning of the edge turner to the changed ones Weaving machine conditions possible.
  • Another advantage of the invention is that additional, means causing the rotation of the rotating disc, e.g. a drive gear connected to the actuator and a Motor rotary drive on toothed belt that transmits the rotating disc, between the servomotor and the rotator disc.
  • additional, means causing the rotation of the rotating disc e.g. a drive gear connected to the actuator and a Motor rotary drive on toothed belt that transmits the rotating disc, between the servomotor and the rotator disc.
  • the rotary edge rotator 1 consists of a disk-like, electrically controllable servomotor 2 with a stator 3 and a rotor, which forms the rotating disk 4 with two passages 4a and 4b arranged symmetrically about the central axis 5 of the rotating disk 4.
  • the passages are preferably designed in the form of a circular arc.
  • a leno thread 6, 7 supplied by rotator bobbins, not shown, is passed through each passage 4a, 4b. Both leno threads 6, 7 form a front leno thread pocket 8 that is adequate for the shed (front pocket) by turning the rotating disc 4.
  • the leno threads 6, 7 are brought together in the binding point 9 of the fabric 10. In the binding point 9, the ends of the respective weft thread 11 are tied by at least half a turn of the rotating disc 4 in the direction of arrow 12 or in the direction of arrow 13 to form a fixed fabric edge.
  • stator 3 forms together with in its interior an annular support part 14 a circumferential U-shaped groove in which the rotary disc 4 is rotatably received.
  • the servomotor 2 is a motor of known operating principle, the stator 3 carrying the windings and the rotor or the rotator disk 4 receiving magnets 15 arranged distributed on the outer circumference.
  • the rotating disc 4 is preferably designed to save mass, namely as a ring.
  • the annular carrier part 14 forms a holder 16 which is connected to a hub 18 by means of connecting elements 17.
  • the hub 18 can also be connected in a rotationally fixed manner to a component 20 via a connecting element 19.
  • the component 20 is firmly connected to a component 21 that can be adjusted to the weaving width of the weaving machine.
  • the edge-turning device shown here is an edge-turning device arranged on the left-hand side of the weaving machine, another 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 strands of the first heald frames, which are behind the reed not shown and are not shown.
  • an electrically controllable servomotor 2 as Direct drive for the rotary disc 4 of the rotary edge driver 1 allows the weaving machine manufacturer on a separate To waive the rotary drive for the leno bobbins because e.g. by programming a number of rotations of the servomotor 2 and thus by a fixed number of revolutions the rotating disc 4 in one direction and through the same number of turns in the opposite direction a loop around the feed from the rotating coils Leno threads 6.7 no longer in the area of the back pocket occurs.
  • a servomotor 2 as a drive for the rotating disk 4 also allows the direction of rotation of the rotating disk 4 weft 11 for weft 11 to be driven in an oscillating manner. In this case, too, a separate drive for the rotating coils is not necessary.
  • weft compaction In the manufacture of borders or so-called weft compaction is through programmed control of the servomotor 2 possible single bonds and misfires too realize. This means that the end of each weft 11th is tied by the leno threads 6,7 or take place Misfiring, i.e. a leno tie only becomes after two or three weft entries.
