Definitions

  • the invention relates to an assembly which contains a nozzle for treating running yarns, having a nozzle body which has a continuous yarn channel which is open laterally to a surface of the nozzle body and a blowing channel which opens into the yarn channel, and having a baffle block which is pressed onto the surface of the nozzle body with a surface in order to close the yarn channel laterally.
  • the baffle block is connected to the nozzle body by a hinge with a hinge pin, so that the baffle block can be lifted off the nozzle body for inserting a yarn into the yarn channel. Because of the inevitable play in such a hinge, it is difficult without special measures to ensure that the surface of the baffle block lies exactly parallel to the surface of the nozzle body and thus a reliably tight lateral closure of the yarn channel. In addition, the nozzle body is relatively complicated and expensive due to the hinge and has a relatively large width perpendicular to the yarn channel.
  • the object of the invention is to avoid these disadvantages and to provide an assembly of the type specified at the outset, in which the tight lateral closure of the yarn channel is always guaranteed in a simple manner and the nozzle body can have a minimum width perpendicular to the yarn channel.
  • the assembly according to the invention is characterized in that the baffle block is connected in a coupling joint-like manner by the baffle block being spring-loaded to the surface of the nozzle body mentioned and to a surface approximately perpendicular to this surface a guide plate rigidly connected to the nozzle body is pressed and can be moved against the spring force, the surface of the baffle block then being in sliding contact with an edge of the nozzle body and an edge of the baffle block being in sliding contact with the surface of the guide plate.
  • the baffle block Due to the sliding contact of the surface of the baffle block with the edge of the nozzle body and the edge of the baffle block with the surface of the guide plate, the baffle block is guided without play during its movement with respect to the nozzle body.
  • the exact same area of the surface of the baffle block always lies above the yarn channel. Any contamination, e.g. Aviva residues that are deposited on this area can therefore not impair the tight contact of the surface of the baffle block on the surface of the nozzle body.
  • the distance from the yarn channel to the mentioned edge of the nozzle body, which preferably runs approximately parallel to the yarn channel, can be relatively small, so that the nozzle body can be made narrow. If required, the nozzle body can therefore be mounted in the assembly in two positions rotated by 180 ° without excessive space requirement. This is important if the blow channel in the nozzle body is inclined to the yarn channel. Depending on the installation position of the nozzle body, the same nozzle body can then be used to obtain a flow in the yarn channel predominantly counter to the yarn direction or with the yarn direction.
  • the nozzle body can preferably be formed essentially symmetrically with respect to a central plane through the yarn channel. Furthermore, it can be releasably attached to a connection part rigidly connected to the guide plate, so that if desired, it can be easily detached from the connecting part at any time and turned upside down, or replaced.
  • the assembly shown in FIGS. 1 to 7 contains a nozzle body 1, which in a surface 2 has a continuous yarn channel 3 which is open laterally towards this surface and into which a blowing channel 4 opens.
  • a surface 5 (FIG. 5) of an impact block 6 is pressed onto the surface 2 in order to close the yarn channel 3 laterally.
  • a running yarn 7, which is only indicated by broken lines in FIG. 1, is passed through the yarn channel 3 and is treated in the yarn channel with a blowing medium, for example compressed air, emerging from the blowing channel 4, in particular a multifilament yarn which passes through the blowing medium is swirled in places.
  • a blowing medium for example compressed air
  • the nozzle body is detachably attached to a connecting part 8, which has a bore 9 for the supply of blowing medium to the blowing channel 4.
  • the bore 9 has an internal thread which receives a blow medium line, not shown.
  • the nozzle body 1 is fastened to the connection part 8 with at least one screw 10 which is screwed into a threaded bore 11 in the connection part 8.
  • the screw 10 is arranged in one of two bores 12 and 13 in the nozzle body 1, which are diametrically opposite to each other with respect to the mouth of the bore 9 in the blow channel 4.
  • the nozzle body 1 can therefore be fastened on the connecting part 8 with the screw 10 in two positions, which are rotated relative to one another by 180 ° about the axis of the mouth of the bore 9.
  • the blowing channel 4 is inclined, as can be seen from FIG. 6, against the axis of the yarn channel 3, so that the blowing medium in FIG. 1 or FIG. 6 flows predominantly to the left in the yarn channel 3, i.e. against the running direction of the yarn 7.
  • the nozzle body is fastened on the connecting part 8 rotated by 180 ° as described, the screw 10 then being arranged in the bore 13, then the blowing medium in the yarn channel 3 predominantly flows to the right in FIG. 1 , ie with the running direction of the yarn 7.
  • the nozzle body 1 including the bores 12 and 13 is, as shown, essentially symmetrical with respect to a plane perpendicular to the surface 2, which goes through the axis of the yarn channel 3.
  • a bolt 14 extends through the free bore 13 (or 12) in the nozzle body 1, of which a threaded lower end section is screwed into a threaded bore 15 in the connecting part 8.
  • the bolt 14 extends with play in or through an opening in the baffle block 6.
  • a compression spring 16 is arranged, which presses the impact block 6 with the surface 5 against the surface 2 of the nozzle body 1.
  • a guide plate 19 is fastened to the connecting part 8 with two screws 17 and 18 and has a guide surface 20 which is approximately parallel to the yarn channel 3 and approximately perpendicular to the surface 2.
  • a second compression spring 21 is arranged in a bore in the baffle block 6 and is supported at one end on the bolt 14 and at the other end on a threaded pin 22 which is screwed into a threaded section of the bore. The spring 21 presses the left or rear surface of the baffle block 6 in FIG. 4 against the surface 20 of the guide plate 19. The pressing force can be adjusted by adjusting the threaded pin 22.
  • the baffle block 6 is movably connected to the nozzle body 1 in a coupling joint-like manner by the baffle block 6 being pressed against the surface 2 of the nozzle body 1 and against the guide surface 20 by the force of the springs 16 and 21.
  • the impact block 6 can be moved against the force of the spring 16 from the closed position shown in FIGS. 1 to 4 into the opening position shown in FIG. 5, in which the yarn channel 3 is freely accessible for inserting a yarn.
  • the surface 5 of the baffle blocks 6 is in sliding contact with an edge 2a of the nozzle body 1 which is spaced from and parallel to the guide surface, and an edge 23 of the baffle block 6 is in sliding contact with the guide surface 20.
  • the baffle block 6 is guided such that it can move with no play with respect to the nozzle body 1.
  • An actuating part 24 for moving the baffle block 6 is fastened to the baffle block 6 with screws 25 and 26 or could also be formed in one piece with the baffle block.
  • the actuating part 24 has an approximately perpendicular to the surface 5 of the baffle block 6 th lever which is pressed to move the baffle block by hand towards the guide plate 19.
  • the assembly shown in FIGS. 8 to 11 again contains the nozzle body 1 with the surface 2 and the yarn channel 3 as well as the baffle block 6.
  • the nozzle body 1 is fastened with the screw 10 on a connecting part 8 'which has a bore 9' for the Has supply of blowing medium to the blowing channel of the nozzle body 1.
  • a shut-off device in the form of a tap with a plug 37 is arranged in a section of the assembled, angled bore 9 ′.
  • the plug 37 can be pivoted between the open position according to FIGS. 8 and 9 and a closed position perpendicular thereto by means of a cranked actuating lever 38.
  • the open position of the actuating lever 38 is shown in FIGS. 8, 9 and 10. Its closed position is shown in Fig. 11 and indicated in Fig. 8 and 10 with broken lines.
  • the bolt 14 is also screwed into the connecting part 8 '. Between the head of the bolt 14 and a counter surface on the baffle block 6, the compression spring 16 is arranged, which presses the baffle block 6 against the surface 2 of the nozzle body 1.
  • a guide plate 19 ' is attached to the connecting part 8', which has a guide surface 20 'approximately parallel to the yarn channel 3 and approximately perpendicular to the surface 2.
  • the baffle block 6 is, as described with reference to FIGS. 1 to 5, movably connected to the nozzle body 1 in the manner of a coupling joint: when the baffle block 6 moves, its surface 5 is in sliding contact with the edge 2a of the nozzle body 1, and the edge 23 of the baffle block 6 with the guide surface 20 'in sliding contact.
  • a holder 39 is attached to the baffle block 6, which carries an actuating part 24 '.
  • the actuating part 24 ' extends on the rear side facing away from the guide surface 20' of the guide plate 19 'approximately parallel to this down to the area of the connecting part 8' and there carries a rearward projecting ramp 40.
  • Two tongues 41 (FIG. 11) are bent out of the actuating part 24 'and resiliently bear against the rear of the guide plate 19' approximately in the region of the impact block 6.
  • the resilient tongues 41 serve to hold the impact block 6 in contact with the guide surface 20 ′ by spring force.
  • Thread guides 43 and 44 are held on the extended guide plate 19 ', which guide the yarn to be treated before it enters the yarn channel 3 and after it exits. Similar thread guides could of course also be connected to the guide plate 19 or to the connecting part 8 in the assembly according to FIGS. 1 to 5.
