Definitions

  • the invention relates to a rotary edge driver for Looms, by means of which by a lathe weave the weft threads were tied at the fabric edges become.
  • This arrangement consists of a rotary driven rotating disc, the geometric center axis of which is parallel to the weft direction of the weaving machine and the rotating disc is driven at the same speed as the bobbin holder carrying the rotating bobbins.
  • the rotating disc has two slots for the leno threads arranged symmetrically to its central axis.
  • the drive on both sides of the weaving machine next to the edge warp threads is carried out in such a way that the rotary disc forming the actual edge rotator is connected via a toothed belt to a drive wheel in a rotationally driven connection.
  • 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 wrench, 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 here with the teeth of a drive gear which drives the rotating coil holder in synchronism with the rotating disc.
  • EP 0 306 078 A1 is a device known for forming a selvedge of a fabric, which a rotating body carrying two coils in a carrier having. On the rotating body are needle-like Guide elements protrude, which ends are guided in a sliding guide and in substantial Distance from the rotating body loops for the leno threads exhibit. By rotating the rotating body the needle-like guide elements in of the sliding guide so that a The weft is tied.
  • the rotary drive can be done by an electric motor whose The rotor of the rotating body is where the carrier forms its stator.
  • the rotary drive can also be derived from the drive of the weaving machine.
  • the edge turner should, in contrast to the stand technology, not for the purpose of changing articles be separated from the weaving machine and the edge turner should be easily to different web widths be customizable. This is supposed to save a lot of makeready times in the weaving mills.
  • the rotary edge turner should also be a simple one have a constructive structure and direct, i.e. without the inclusion of a means of transmission between the servomotor and the rotating disc, can be driven his.
  • the problem is solved 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 turning machines 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.
  • Rotary disc including ultimately an oscillating one Reversal of the direction of rotation can be understood on the Drive of the rotating coil holder can be dispensed with, because in every case the twists or loops the leno threads on the way between the Rotary coils and the rotating disc through a certain number of right turns Rotary disc, by the same number of left turns the same rotating disc, picked up again become.
  • This edge turner can be positioned as close as possible to the weaving point of the fabric and between the shaft frame and the healds of the first heald frames. This means that the number of usable heald frames in the warp beam direction, ie opposite to the weaving direction, is not limited.
  • edge turner Due to the compact design of the edge turner is in the event of an article change or a weave width adjustment a quick positioning of the edge turner to the changed conditions of the weaving machine possible.
  • the one seen in the weaving direction in front of the heald frames is arranged with the arrangement of the invention
  • Rotary edger within the Heald frames arranged closest to the reed are clear that the stroke of the leno threads when used of a rotary edge turner only about 80 mm is during the leno threads with a satellite lathe have to perform a stroke of approximately 180 mm, in order to achieve a sufficient compartment opening.
  • Another advantage of the invention is that additional ones which drive the rotating disc Agents such as a drive gear connected to the servomotor and the motor rotary drive on the Toothed belt transmitting toothed pulley, between the servomotor and the rotating disc are eliminated.
  • the rotary edge rotator 1 consists of a disc-like, electrically controllable servomotor 2 with a stator 3 and a rotor, which forms the rotating disc 4 with two passages 4a and 4b arranged symmetrically about the central axis 5 of the rotating disc 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 which 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 in its interior with an annular support part 14 a circumferential U-shaped groove in which the rotating disc 4 is rotated.
  • the servomotor 2 is a motor known operating principle, the stator 3 the windings carries and the rotor or the rotating disc 4 magnets 15 distributed around the outer circumference receives.
  • the rotating disc 4 is preferably mass-saving here namely as a ring.
  • the ring-shaped carrier part 14 forms a holder 16 which is connected to a hub 18 with 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 turners are arranged in the area of the free space between the heald frames, not shown here, and strands of the first heald frames, which are behind the reed not shown and are not shown.
  • an electrically controllable Actuator 2 as a direct drive for the rotary disc 4 of the rotary edge rotator 1 allows the weaving machine manufacturer on a separate 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 of the rotating disc 4 in one direction and by the same number of turns in the opposite Towards a looping of the Leno threads 6,7 in the area of the back compartment no longer occurs.
