Definitions

  • the invention relates to a delivery device for running threads, in particular for use on textile machines, according to the preamble of claim 1.
  • a delivery device of the type in question is known from DE-OS 37 34 284, wherein the thread end conveyed by compressed air through the thread guide tube, after leaving the thread guide tube in the area in front of the storage drum, is directed from a blow nozzle oriented approximately parallel to the drum axis into a radially slotted guide channel becomes. This passes through the brake ring in the area of the root of the bristles and forms a channel section curved beyond the brake ring in the direction of the drum axis. A further blowing air nozzle opens into this in such a way that its jet runs radially to the drum axis and directs the thread into a channel-like, approximately triangular section of the head cone. The thread end is guided through this into the area of a suction blowing nozzle.
  • a disadvantage of this configuration is the complex construction of the thread delivery device, due to the blowing air nozzles and additional channels required at the deflection points.
  • the object on which the invention is based is now to design a delivery device of the aforementioned type in a technically simple manner in such a way that automatic, reliable threading of the thread is made possible with a minimum of components and nozzles.
  • a generic delivery device for running threads with a simple structure is specified, which is characterized by reliable threading of the thread using compressed air.
  • the number of nozzles working with compressed air is reduced to a minimum.
  • the thread blown through the thread guide tube now emerges in a plane vertically above the thread take-off eyelet in such a way that the thread end runs approximately parallel to the drum jacket surface, then is grasped along the jacket surface of the head cone by means of the suction air flow and is further conveyed while passing through the thread take-off eye. This is done using the force of gravity acting on the thread end, which has a supporting effect on the threading process.
  • the thread end is therefore always detected with certainty and sucked into the thread take-off eyelet.
  • Additional deflection nozzles in order to obtain a corresponding course of the thread direction can accordingly be dispensed with, combined with reduced manufacturing costs for the delivery device.
  • a channeling of the head cone is also not necessary, so that it can maintain its smooth surface, which favors the thread take-off.
  • the configuration according to the invention allows working with customary, available compressed air values.
  • the threading process is further supported by the fact that the suction blow nozzle assigned to the thread take-off eyelet is arranged in a baffle for the blowing stream emerging from the thread guide tube.
  • this baffle fulfills a double function: on the one hand, it serves to hold the suction blowing nozzle and, on the other hand, there is also a deflection wall for the thread end, so that it does not shoot past the suction blowing nozzle, but favors the threading process.
  • Manufacturing advantages of the delivery device also result from a suction blow nozzle in front of the end of the thread guide tube on the insertion side.
  • This suction blow nozzle can have the same structure as the thread take-off eyelet designed as an axial suction blow nozzle, while reducing the number of different components.
  • the brake ring In order to enable threading of the thread, the brake ring must first have been displaced in the axial direction of the storage drum in such a way that its bristles leave a gap to the drum jacket surface, so that the thread end can take its intended path under the bristles.
  • the brake ring In order to achieve a favorable position of the brake ring in its working and disengaging position, the brake ring is adjustable on a sliding carriage. Independent of the displacement stroke of the brake ring, the individual setting can therefore always be made.
  • the thread guide tube bent in the axial direction of the drum always directs the thread end in such a way that it is directed into the previously left gap. The thread end therefore always comes to the thread take-off eye as intended.
  • the thread in which a correspondingly bent guide end is missing on the thread guide tube, the thread can be taken over and deflected by a deflection channel running in the axial direction, into which the mouth end of the thread guide tube is directed.
  • a deflection channel running in the axial direction, into which the mouth end of the thread guide tube is directed.
  • the suction blow nozzle arranged at the insertion end of the thread guide tube, the thread end is always brought into the suction area of the thread take-off eyelet designed as an axial suction blow nozzle.
  • These two suction blow nozzles work on the Venturi principle.
  • the suction blowing nozzles are constructed so that an annular chamber is arranged upstream of their annular gap. The wall forming the same annular gap is provided with a ring of air passage holes.
  • the bristles can be adjusted in a simple manner by means of an adjusting screw accessible from the head end.
  • an adjusting screw accessible from the head end.
  • the sliding carriage carrying the brake ring changes its position in relation to the storage drum.
  • This set screw passes through an opening in the baffle and can be operated from there.
  • the lateral surface area of the head cone lying behind the baffle runs in a straight line from the base edge to the tip of the cone, achieving a favorable thread steering. This in turn ends in front of the suction blowing nozzle there.
  • the air supply to both suction blowing nozzles is approximately the same, so that work can be carried out with the same pressure and the same line cross sections, which likewise contributes to a simplification in the construction of the delivery device.
  • the delivery device has a housing 1 to be fastened, for example, to a carrier of a weaving machine.
  • This houses a stator 3 in a housing cavity 2, in which a rotor 4 rotates.
  • the latter is penetrated by a rotor shaft 5.
  • Its thread-threading end sits in a roller bearing 6, which is inserted in a cover 7 closing the housing cavity 2.
  • a cross-sectionally larger collar 8 of the rotor shaft 5 facing away from the threading end starts from an inclined thread guide tube 9, the mouth end 10 of which is bent in the axial direction of a storage drum 11 arranged coaxially to the rotor shaft 5.
  • the storage drum 11 forms a thread run-up truncated cone surface 12, so that when the thread guide tube 9 rotates, the rear thread turns advance the front thread turns already on the storage drum toward the head end of the storage drum 11.
  • the storage drum itself is rotatably arranged. So that it does not rotate together with the thread guide tube 9, it is firmly connected to a truncated cone 13 equipped with magnets, not shown. Its magnets are located opposite to fixed magnets 14 of a ring 15 on the housing side.
  • the storage drum 11 At its free-flying front end, the storage drum 11 carries a head cone 16. Its base lies against the front side of the storage drum and is somewhat smaller than the diameter of the storage drum 11.
  • the lateral surface area M of the head cone 16 starts from the base edge B and extends in a straight line up to to the cone tip 17. The same extends to the inlet opening 18 of a thread take-off eye 19.
  • the extension arm 21 which extends beyond the storage drum 11 is located at such a parallel distance from the storage drum 11 that it does not impair the orbital movement of the thread guide tube 9.
  • the boom 21 receives a compressed air cylinder 22. Its piston rod 23 engages a sliding carriage 24 which is longitudinally displaceable in the interior of the boom 21. Relative to this, a carrier 25 is guided for a brake ring 26 that runs concentrically to the storage drum axis.
  • the sliding carriage 24 supports an adjusting screw 27, for the actuating end 28 of which the baffle 20 forms an opening 29. Rotating the actuating handle 28 is accompanied by a longitudinal displacement of the carrier 25, depending on the direction in which the brake ring 26 is to be adjusted.
  • the brake ring 26 is provided with bristles 30 directed toward the drum in such a way that they are aligned with the lateral surface of the head cone 16. In the working position, the bristle ends rest against the head cone 16 of the storage drum 11.
  • the thread guide tube 9 continues into a thread channel 31 which extends centrally through the rotor shaft and which widens at the end on the threading side.
  • a suction blow nozzle 32 is provided in the housing cover 7.
  • a spacer sleeve 33 In a central opening of the housing cover 7 there is a spacer sleeve 33 in which the nozzle housing 34 is firmly inserted.
  • the nozzle housing 34 receives at its end facing the rotor shaft 5 a sealing collar 35 which extends to the free end of the rotor shaft 5. Accordingly, the thread channel 31 directly adjoins the outlet opening 36 of the sealing collar 35.
  • the outlet opening 36 in turn is connected to a short through-flow channel 37 of the nozzle body 34, which channel 37 subsequently widens into a frustoconical channel 38 in order to then merge into a circular-cylindrical channel section 39.
  • a nozzle body 40 is pressed into this. In the middle, it forms a thread passage channel 41, which is smaller in diameter than that of the flow channel 37 in the nozzle body 34.
  • the nozzle body 40 is equipped with a truncated cone section 42, the cone angle of which is smaller than that of the truncated cone Channel 38.
  • the smallest diameter of the truncated cone section 42 is smaller than that of the flow channel 37, so that an annular gap 43 remains accordingly.
  • the nozzle body 40 On its circular-cylindrical remaining length, the nozzle body 40 forms an annular chamber 44, in whose wall 45 on the annular gap side a ring of air passage holes 46 is provided. A compressed air supply line 47 opens into the annular chamber 44. A threading eyelet 48 is then arranged upstream of the nozzle body 40 and is in turn firmly embedded in the nozzle housing 44.
  • the thread take-off eye 19 is also designed as a suction blowing nozzle. It has a nozzle housing 49 inserted into the baffle wall 20 with a nozzle body 50 which corresponds in structure to that of the suction blowing nozzle 32.
  • a common valve 52 is assigned to the feed lines 47, 51 of the two suction blowing nozzles 19, 32. The latter is connected to a compressed air source 54 via a compressed air line 53.
  • a feed line 55 extends from the valve 52 to a distributor 56, which is connected both to the supply lines 47, 51 and to the supply line 57, which leads to the compressed air cylinder 22 .
  • the valve 52 can be controlled by means of a handle 58.
  • both the suction blowing nozzles 19, 32 and the compressed air cylinder 22 are fed via the compressed air line 53 and feed line 55 via the distributor 56, which displaces the brake ring 26 in the axial direction in such a way that its bristles enter a gap position with respect to the drum surface, see gap 60 in Fig. 3.
  • the aforementioned handle 58 is advantageously located on a box 59 connected to the housing 1, in which the valve 52 as well as the distributor 56 and the corresponding connections are accommodated.
  • the width of the baffle 20 receiving the suction blowing nozzle 19 corresponds approximately to one third of the diameter of the storage drum 11.
  • the rotor shaft 5 Before threading a thread F, the rotor shaft 5 is stopped in such a position that the thread guide tube 9 originating from the collar 8 or its mouth end 10 lies in a plane vertically above the thread take-off eye 19.
  • the handle 58 is then to be actuated, the suction blowing nozzles 19, 32 receiving compressed air at the same time.
  • This also applies to the compressed air cylinder 22, which displaces the brake ring 26 via its piston rod 23 and sliding carriage 24, so that its bristles reach a gap-forming release position, cf. Fig. 3.
  • the thread end is now to be brought into the area of the threading eyelet 48.
  • the radially inward on the thread take-off Eyelet 19 directed deflection then takes place by means of the suction air flow lying on the lateral surface of the head cone 16, which deflection is supported by the gravity of the thread end.
  • the baffle 20 represents a limitation of the trajectory, so that the thread end does not go beyond the baffle, but surely reaches the extraction eyelet 19 designed as a suction blow nozzle and from there also emerges from the venturi principle.
  • the handle 58 can return to its starting position with the interruption of the compressed air supply.
  • a spring, not shown, housed in the compressed air cylinder 22 then returns the brake ring 26 to its starting position.
  • the bent mouth end 10 is missing in the thread guide tube 9.
  • the mouth end 61 which in this second exemplary embodiment extends in the same direction as the thread guide tube, is directed into a deflection channel 62 running parallel to the storage drum axis direction. This is located in a block 63 inserted into the boom 21 and extending below the compressed air cylinder 22.
  • the deflection channel 62 has three adjoining bottom sections 62 ', 62 ", 62"'.
  • the third bottom section 62'" runs at an opposite angle to the drum axis and directs the thread end into the gap 60 between bristles 30 and storage drum in the direction of the head cone 16, baffle 20 and suction blow nozzle 19.
  • the threading process is also carried out while the handle 58 is pressed.
  • the deflection of the thread now takes place in the transition region between the mouth end 61 and the suction blowing nozzle 19 through the deflection channel 62, so that additional deflection nozzles can also be omitted in this version.
  • the funnel-shaped enlargement 64 of the deflection channel 62 on the input side has a facilitating effect during the threading process.
  • the threading of the thread always takes place in the position in which the mouth end 51 of the thread guide tube 9 is located in a plane vertically above the thread take-off eye. Then both the force of gravity and the corresponding lateral surface of the head cone located in the same plane can be used for thread guidance.
