Definitions

  • the invention relates to a delivery device specified in the preamble of claim 1 Art.
  • a delivery device of this type is known from DE 30 32 971 C and is there in alternation operated with at least one other similar delivery device. It is a matter of a measuring device that measures the length of the thread entered during a shot.
  • a measuring device that measures the length of the thread entered during a shot.
  • the stop element acts as a conveying element for the windings on the storage body and terminates the respective Shot. Since the stopper is unable to initiate the shot is provided downstream of a controlled thread clamp, which clamps the thread while the stop element is moved away from the turns. The adjustment or Opening the thread clamp in the passive position initiates the shot.
  • a controlled thread clamp which clamps the thread while the stop element is moved away from the turns.
  • the adjustment or Opening the thread clamp in the passive position initiates the shot.
  • the mechanical load for the thread is high.
  • the mechanical load and the large storage body diameter conditional strong balloon effect can at high yarn withdrawal speed frequent thread breaks or weft disturbances and entry delays cause.
  • Each stop element is a Tooth of a gear, which in the derived from the drive shaft of the winding member Drive movement of the gear gradually between the turns on the Storage area is pushed and then moved forward with the windings, before he stopped in the stop position the shot.
  • the needed for the initiation of the shot Thread clamp is provided on the storage body.
  • the delivery device needed because of the slow forced movement of each stop element for higher firing speeds and because of the space of the drive a storage body with relatively large diameter, the undesirable strong balloon effect (mechanical load in the thread and time delay) conditioned.
  • the invention is based on the object, a delivery device of the type mentioned to create that for high shooting frequencies and high shooting speeds also suitable for sensitive thread material works largely trouble-free, and optimally short shot times possible.
  • the combination of a small diameter storage body and one exclusively axially movable into the stop position by the turns during their conveying movement Stoppelements makes it possible surprisingly, the yarn feeding device largely trouble-free even for high shooting frequencies and / or shooting speeds even to use with sensitive thread material.
  • the small diameter Storage body reduces the balloon effect or cached in the thread balloon kinetic energy so that without excessive mechanical Loading the thread highest firing speeds and especially short Shot times are possible.
  • Due to the small diameter storage body a large number of turns for each shot and avoiding mechanical Impairment of Windungsschien on the storage body by the stop element. This requirement meets the stop element when it is exclusive is moved axially by the windings in the stop position.
  • the stop element does not need a drive for this movement, because it took away from the turns and the conveying motion of the turns, which in other ways during the winding process is generated with minimal or no mechanical resistance follows (stop element dragged by the windings). Because the movement the stop element in the stop position requires no control from outside or inside, the drive of the stop element only needs the precise engagement of the stop element between the turns control, and later to disengage the intervention again. In combination, these features result in a synergistic effect that increases high operational reliability even at high thread speed and / or too short firing times and / or high firing frequency leads.
  • Under a small diameter Storage body is understood here as a storage body, the opposite to the conventional tendency for delivery devices with thread sizing function has a significantly smaller outer diameter.
  • a large storage body is also used to suit everyone Shot as few turns, and also an axially short thread stock, to have on the storage body.
  • the balloon effect is also at high shooting speed desirably low.
  • the centrifugal force in the thread is approximately the square of the radius of curvature proportional.
  • the small diameter allows incredibly short Shot times with moderate energy use, because the thread willingly peel off leaves.
  • Such a small storage body can also be used for delivery devices for projectile or Rapier looms, e.g. with one with the small storage body cooperating trigger brake. The stop element and. the thread clamp would be then possibly not necessary.
  • the outer diameter may be so small that the axial length of the storage surface is much larger than the outer diameter.
  • the stop element via a joint with an axially stationary Radialverstellantrieb connected, which precisely timed the stop element and accurate set to engage in front of the just arriving thread turn from the winding member. Thereafter, the joint or the bending area remains the stop element Degree of freedom, thanks to which he is essentially powerless by the conveyor movement bring the turns on the storage body with these up to the stop position leaves.
  • stop element can be moved back axially to order for the next To be able to stand up the thread sizing function before the first arising turn, An Axialverstellantrieb is used, which the stop element in the release position resets in the joint or bending area. Alternatively, several could be consecutive working stop elements are used.
  • the stop element In the stop position, the stop element should be caught at an axial stop become.
  • This stop can be in the storage body or radially outside the Storage body be arranged.
  • the stopper in the stop position a stop damper attributed to mitigate the draft. This measure is reduced the danger of a thread break lasting.
  • the stopper dampened through elastic yielding energy from the delayed thread into the stop element is initiated. For example, the stop moves against the stop element Spring force over a small stroke either in the axial direction, in an oblique Direction or in the circumferential direction of the storage body to consume this energy. It could even be the stop element elastically deformable in itself, the stop damping as soon as the thread stops abruptly and simultaneously the stop element is applied to the stop.
  • the thread clamp by a Actuating magnet to open while the active armature of the actuating magnet to allow against the clamping element of the thread clamp a Leerhub.
  • the actuating solenoid When the actuating solenoid is energized, the valve uses the idle stroke without the mass of the clamping element and the opposite spring force to first accelerate and build up kinetic energy, and only after hitting the Idle stroke with high acceleration and / or high kinetic energy Shift clamping element abruptly in the passive position. That way an opening time of the order of only a few milliseconds or less achieve.
  • the thread already clamped thread clamp approximately opposite to the withdrawal direction of the thread to the storage body to adjust.
  • an actuator for example, a stepper motor
  • the thread clamp shifts or pivots.
  • a delivery device F (FIGS. 1 and 2) with thread length dimensioning function for a weaving machine T has a stationary support 1, on which a storage body K is arranged, for example, similar to a rod cage with axially extending Rods 3, whose outer surfaces are approximately cylindrical or in Fig. 1 define right tapered storage area 4.
  • the rods 3 are with foot parts. 5 attached to the carrier 1 so that they are radially adjusted in a certain area (Radialverstellvorraumen 6) to the outer diameter D of Memory body to adapt to the weaving width to vary.
  • the outer diameter D of the storage body K defines a circumferential curvature of the storage area 4, which is essentially related to the natural storage capacity of natural, Synthetic or mixed thread material for its smallest unforced curvature corresponds.
  • the outer diameter D is only between about 25 and 55 mm.
  • the outer diameter D is only about 35 to 40 mm.
  • the axial length of the storage surface 4 (L in Fig. 2) may be longer than the dimension the outer diameter D.
  • a winding member W for example a winding tube, which is connected to a hollow drive shaft, not shown is.
  • the stop 7 may be an elastically yielding stop damper G (indicated by dashed lines) be assigned.
  • the stop element 5 could also be at a different position than be arranged below.
  • a clamping region 8 of a thread clamp C In front of the free end of the memory body K and approximately axially aligned the position of the stop element S is a clamping region 8 of a thread clamp C.
  • the thread clamp C preferably has a quick-opening mechanism 9, with a clamping element 13 against the force of a spring 12 in a passive position adjustable (to open), in which a held in the clamping area 8 thread Y is released.
  • a fitting A of an actuating magnet M in the direction of arrow 14 adjusted to the clamping member 13 from that shown in Fig. 1 Adjust clamping position to its passive position.
  • the thread clamp C by means of an actuator 10 in approximately parallel to Axis of the storage body or curved (double arrow 11, 11 ") back and forth, e.g. to be panned.
  • the Thread turns by permanent winding by means of the winding member 2 in the direction to the front end of the storage body K conveyed forward (conveying movement B).
  • Fig. 2 is dashed as an alternative feeding device V indicated, for example is driven via the drive shaft of the winding member W, and the thread turns YT separated from each other and / or promotes the front end.
  • the stop element S is a pin 15, which has a joint or a bending region 16 is connected to an axially stationary Radialverstellantrieb 17, e.g. a magnetic drive.
  • the Radialverstellantrieb 17 is capable of the joint 16 in the direction of Double arrow 18 back and forth, namely, the stop element S in engagement with the windings YT (as shown) to push or in a release position (not shown in the stop element S has no influence on the turns YT takes.
  • the stop element S is shown as it just in the Way of the first arising turn YT intervenes. In the further rotation the winding member W permanent new turns are formed.
  • the conveyor movement B moves the stop element S to the stop position (dashed line) at the stop 7.
  • the pin 15 has a degree of freedom in the joint or bending region 16, thanks to which he follows the conveying movement B substantially powerless.
  • the thread Y is against further withdrawal abruptly blocked.
  • the thread clamp C is in its passive position.
  • the stop 7 could also be outside the storage body K be positioned, as indicated for example at 7 '.
  • An axial drive 19, e.g. an electromagnet displaces the one that has reached the release position Stop element S back to the position in which it (drawn drawn) again before the first resulting turn is engageable.
  • the thread clamp C is in the Adjusted passive position. Thanks to the further rotation of the winding member W is the stop element is again brought from the turns YT to the stop position, in which then finishes the shot.
