Definitions

  • the invention relates to a delivery device according to the preamble of claim 1.
  • the second thread control device is a controlled thread clamp arranged downstream of the storage body in the thread path in the draw-off direction of the thread longitudinal sections.
  • the storage body is assigned two pin-shaped stop elements which are moved alternately axially and radially in order to initiate or terminate the respective take-off and to dimension the longitudinal thread sections.
  • a stop element transfers windings representing a dimensioned longitudinal section to the other stop element.
  • both stop elements operate outside the storage body. The winding transfers inevitably mean irregularities in the course of the thread control, since no transfers take place in the other work phases.
  • a controlled thread clamp is additionally required downstream of the storage body, which initiates each withdrawal.
  • the delivery devices according to US 4 132 370, US 449863, DE 3032971 A, EP 0250359 A require, because of the mechanism for controlling the movement of the stop elements inside the storage body, a large storage body with a diameter of at least about 120 mm as a rule, but which has a pronounced balloon effect at high thread speeds generated in the withdrawn thread.
  • a strong balloon effect does not allow flight times or entry frequencies that do justice to the performance of modern air jet looms.
  • the mechanical drive controls of the stop elements in the known delivery devices are technically complex and prone to failure.
  • the drive concepts would not be expedient for a small-diameter storage body, because the small-diameter storage body has to work at a high winding speed, there is too little installation space for mechanical drives in the storage body, and unusually high drive powers would be required due to the power losses in the mechanical gears.
  • the cam controls of the delivery device according to EP 0 098 254 are unsuitable for high winding speeds, such as are used in small-diameter storage bodies, due to the large moving masses and unavoidable mechanical play.
  • the invention has for its object to provide a delivery device of the type mentioned with short flight times and high entry frequencies, small specify messy storage body that enables a uniform and therefore low-interference intermittent thread control, the construction effort in the movement controls of the stop elements should be low.
  • the second, pin-shaped stop element only has to be moved essentially radially to the axis of the storage body in order to initiate a deduction
  • a structurally simple and fast movement control can be used for the second stop element.
  • the movement control of the first stop element can also be made simple, since the first stop element does not initiate a draw-off, but only has to dimension the longitudinal thread section and end the draw-off.
  • the second stop element initiates each take-off at the same axial position of the storage surface, and the first stop element ends the take-off near the second stop element, there is a uniform intermittent thread control.
  • a thread clamp downstream of the storage body can be omitted, which could have undesirable influences on the thread control. If windings perform any axial movement in the take-off direction when transferring to the second stop element, any trailing movement of the free thread end in the insertion device of the weaving machine remains negligibly small due to the small-diameter storage body.
  • the two stop elements are arranged relative to one another in such a way that the first stop element transfers turns to the second stop element without any significant wobble movement in the thread extending from the delivery device to the weaving machine. This is the case if the position of the second stop element is adjacent to the stop position of the first stop element, so that the foremost turn in the take-off direction is taken over directly by the second stop element when the first stop element is moved from its stop position to the release position and returns to the thread dimensioning position.
  • the second stop element is preferably located at a position which lies in the axial direction of the storage body between the stop position of the first stop element and the front end of the storage body, and / or in the winding direction, ie in the circumferential direction of the storage body, behind or next to the Stop position of the first stop element. Basically, it can be said that the second stop element is positioned as close to the stop position of the first stop element as the structural options allow.
  • the first stop element expediently essentially borders directly on the second stop element moved into the engagement position. There may even be a direct contact, so that the second stop element forms a stop for the first stop element and defines the stop position of the first stop element.
  • the first stop element can be concavely hollowed out on its side pointing in the withdrawal direction, in order to then be able to nestle as closely as possible to the second stop element in the stop position.
  • the functions of the first and second stop elements are the same for each deduction.
  • the second stop element stops the thread after a pull has ended, while the first stop element carries out its thread dimensioning function and moves in the direction of the stop position.
  • the second stop element is only moved essentially radially from its engagement position into the passive position after, for example, a trigger signal has been emitted by the weaving machine. Due to the further winding of windings and / or by a forced movement and / or by the increasing tensile force towards the end of the deduction, the first stop element comes into the stop position, in which it ends the withdrawal, while the second stop element remains in its passive position.
  • the second stop element is brought back into its engaged position and the first stop element is moved from the stop position into the release position and also immediately towards the thread dimensioning position in order to carry out the next thread dimensioning function.
  • the first stop element In order to influence the thread turns as little as possible and to be able to use a simple drive control for the first stop element, the first stop element is moved in its engagement position from the thread dimension position to the stop position by the thread turns themselves. This movement takes place very quickly due to the high winding speed on the small-diameter storage body.
  • a drive in the movement control can control this movement of the first stop element from the thread dimension position into the stop position, for example in order to precisely define the time at which the take-off ends.
  • the storage body should only have a diameter between approximately 25 and approximately 60 mm, preferably between approximately 30 and 45 mm, the diameter, preferably, should be variable in order to be able to adapt to the weaving width.
  • only the ends of the two stop elements in the stop position of the first stop element and the engagement position of the second stop element should be as close as possible to one another and the stop elements should be spaced apart from one another. This can be achieved by interlacing, angular positioning, cranking or similar measures without impairing the thread control function of both stop elements.
  • FIG. 1 is a schematic perspective view of part of a delivery device
  • Fig. 8 is a side view
  • FIG. 9 shows a cross section of a motion control with a first stop element.
  • a delivery device F (FIG. 1) with a thread dimensioning function for a weaving machine (not shown) has a stationary carrier 1, on which a storage body K is arranged.
  • the storage body K resembles, for example, a rod cage with axially extending rods 3, the outer surfaces of which define an approximately cylindrical, preferably tapering to the right in FIG. 1, storage surface 4.
  • the rods 3 are attached to the support 1 with foot parts 5 such that they can be adjusted radially in a certain area (radial adjustment devices 6) in order to be able to vary the outer diameter d of the storage body K to adapt to the weaving width.
  • the outer diameter d of the storage body K is only approximately between 25 and 60 mm, preferably approximately 30 to 45 mm.
  • the length of the storage surface 4 in the direction of the axis X of the storage body is greater than the dimension of the outer diameter d.
  • a winding member W rotates around the outer periphery of the carrier 1 (winding direction 2), for example a winding tube carrying an outlet eyelet, which is connected to a hollow drive shaft (not shown).
  • a first and a second, in each case pin-shaped, stop element S1, S2 are assigned to the winding body K.
  • Each stop element S1, S2 is arranged in a stationary movement control, not shown in FIG. 1, the two movement controls possibly being combined in one housing.
  • the stop elements S1, S2 are moved cyclically and as indicated by curves A, B, e.g. depending on the rotational movement of the winding element W and / or the work cycles of the weaving machine.
  • the stop elements S1, S2 are moved in planes which are oriented essentially radially to the X axis.
  • a thread not shown in FIG. 1 extends from the winding element W to the storage surface 4 and is wound thereon in adjacent windings which move forward in the direction of the axis X parallel to one another and form a thread supply, which is temporarily stored on the winding body K.
  • the weaving machine not shown, for example an air-jet weaving machine with a main nozzle, draws a longitudinal section of the thread for each entry from this thread supply, the stop elements S1, S2 in cooperation dimension the longitudinal section intended for deduction, the second stop element S2 initiates the deduction, and the first stop element S1 ends the deduction.
  • the triggering of the take-off is triggered, for example, by a trigger signal transmitted by the weaving machine.
  • the movement sequence of the first stop element S1 is first explained using curve B.
  • the stop element S1 is initially moved essentially radially to the axis X between an engagement position in the thread path and in the storage surface 4 and a release position outside the thread path and outside the storage surface 4, the engagement position being held along the curve part 12 while the Release position is held along the curve part 9.
  • the first stop element S1 is also moved in the axial direction, specifically by driving the drive control along and in the arrow direction of the curve part 9, but in the arrow direction and along the curve part 12 through the windings themselves.
  • the movement control can of the first stop element S1 also contain a drive which positively controls the movement of the first stop element S1 along the curve part 12.
  • the tip of the first stop element S1 expediently moves in the engagement position in an axial groove or an axial slot of a rod 3.
  • the second stop element S2 also engages there. This is to prevent loops from slipping through.
  • the stop element S1 In the engaged position of the stop element S1, it is moved in the direction of the arrow between a thread dimensioning layer 11 and a stop layer 7, either by the windings themselves or by a drive, not shown.
  • the stop element S1 In the release position, the stop element S1 is moved along the curve part 9 from a location 8 corresponding to the stop position 7 to a location 10 corresponding to the thread dimension position 11, by means of a drive of the movement control.
  • the stop element S1 is pulled from the stop position 7 in the direction of the arrow to the location 8.
  • the stop element S1 is pushed from the location 10 in the direction of the arrow into the thread dimensioning layer 11.
  • the sequence of movements (curve A) of the second stop element S2 is different because the second stop element S1 is essentially only moved back and forth radially to the axis X, specifically between an engagement position 7 ′ in which it engages in the thread path and the storage surface 4 and a passive position 8 ', in which it is withdrawn from the storage surface 4 and from the thread path.
  • the first second stop elements S1, S2 are essentially one behind the other in the direction of the axis X.
  • the second stop element S2 could also be offset in the circumferential direction of the storage surface 4 with respect to the first stop element S1.
  • the movements of the two stop elements S1, S2 are coordinated with one another such that the first stop element is then moved from a stop position 7 over location 8 and along curve part 9 and location 10 into thread dimensioning position 11, while second stop element S2 moves into its engaged position T occupies.
  • the second stop element S2 is only moved into its passive position 8 ′ when the first stop element S1 is in its engagement position along the curve part 12.
  • the thread dimensioning layer 11 of the first stop element S1 is defined such that the first stop element S1 engages in the thread path precisely between the last turn intended for a take-off and the first turn just formed by the winding element W for the next take-off.
  • the work flow of the delivery device F of FIG. 1 is explained with reference to FIGS. 2 to 6.
  • the second stop element S2 is in its engagement position 7 ′, so that the thread Y, which extends over the front end of the storage body K, is held. Thread turns are already present upstream of the second stop element S2.
  • the first stop element S2 is in its engagement position along the curve part 12 and moves with the continuously wound turns in the direction of the second stop element S2.
  • the thread section dimensioned for a draw-off is defined by the turns present between the first and second stop elements S1, S2. Upstream of the first stop element S1 there are also windings on the storage surface 4.
  • the loom emits a trigger signal because a take-off is to be initiated.
  • the second stop element S2 is pulled from the engagement position 7 'of FIG. 2 into the passive position 8' of FIG. 3 from the thread path. With this, the take-off is initiated and the thread (arrow 14) moves into the weaving machine.
  • the windings held ready downstream of the first stop element S1 are unwound.
  • the first stop element S1 moves further along its curve part 12 and in the axial direction to the second stop element S2. Further turns are wound upstream of the first stop element S1.
  • the first stop element S1 After all windings have been unwound downstream of the first stop element S1, the first stop element S1 reaches its stop position 7, for example at a stationary stop 13 (FIG. 4).
  • the stop 13 can be provided in the storage body or outside the storage body or also in the movement control of the first stop element S1. Alternatively, the stop 13 could be formed directly by the second stop element S2. In the working phase in FIG. 4, there are even fewer turns upstream of the first stop element S1 than are required for a take-off. As soon as the first stop element S1 has reached its stop position 7, for example at the stop 13, the deduction has ended.
  • the second stop element S2 With the end of the trigger or after this, the second stop element S2 is shifted from its passive position 8 'back into its engagement position T (FIG. 5).
  • the first stop element S1 is moved radially outward from its stop position 7 to the location 8 out of the thread path and immediately further along the curve part 9 in the direction of the thread dimensioning position.
  • the windings present upstream of the first stop element S1 are transferred to the second stop element S2.
  • the first stop element S1 is adjusted again via the location 10 into the thread dimensioning position 11 (FIG. 6), exactly behind the last turn required for the next draw-off and before the first turn emerging from the winding element W for the further draw-off. With the winding of further turns, the first stop element S1 moves along the curve part 12 until the working phase according to FIG.
  • FIG. 7 shows in a dashed area 25 of the storage surface 4 the possible positions of the second stop element S2, indicated by crosses, in relation to the position of the first stop element S1 in the stop position 7.
  • This area lies within a field defined by the thread Y.
  • the position of the second stop element S2 should be as close as possible to the position of the first stop element S1 in the stop position 7, so that the thread turns can be transferred reliably. Positions of the second stop element S2 are possible, in which it lies in the axial direction between the first stop element S1 and the front end of the storage body, or in the winding direction 2 is offset to the rear in the circumferential direction.
  • FIG. 7 shows in dashed lines the movement path of the first stop element S1 between the location 10 and the thread dimensioning layer 11 and the stop position 7.
