Definitions

  • the invention relates to a device for shearing fabric webs with a shear cylinder provided with shear spirals arranged above a fabric web support and designed as a hollow cylinder, the interior of which is connected to a suction device generating this vacuum and the jacket of which is provided with air passage openings.
  • Such a device is known for example from DE-A No. 1635304.
  • the air layer surrounding the shear cylinder is sucked in through the air passage openings arranged in its jacket and transported away through the interior of the shear cylinder.
  • the purpose of suction is to straighten the fibers of the web (pile or threads) at the shear point and to cut off sheared threads.
  • the interior of the shear cylinder is connected to a vacuum suction source via pipes.
  • the aim of the present invention is to reduce the expenditure on equipment of such a device.
  • the suction device consists of at least one fan, the rotor of which is connected to the latter in a rotationally fixed manner in or at the end region of the shear cylinder.
  • a fan can be provided only in or on one end region of the shear cylinder, while the other end region is closed.
  • each end region of the shear cylinder has a fan and that the two fans are arranged in opposite directions.
  • the invention creates a self-extracting shear cylinder in which a separate vacuum suction source is completely unnecessary. This not only drastically reduces the outlay in terms of equipment compared to the previously known device, but also gives a considerable further advantage. Because the at least one fan rotates synchronously with the shear cylinder, the delivery rate of the fan increases with increasing rotational speed of the shear cylinder.
  • the device according to the invention therefore has a fully automatic suction power control which, in the case of the known device, could only be achieved by special control apparatuses and circuits.
  • a suction power control is particularly advantageous in the case of shear cylinders having shear spirals, because such shear cylinders have a pronounced self-ventilation, which has the disadvantageous consequence that the threads which are actually to be erected or the pile to be lifted are pressed down in the shear zone. With the appropriate design of the fans, this self-ventilation effect can be drastically reduced or even eliminated with the device according to the invention.
  • shear cylinder is rotatably mounted on its outer casing, so that the full cross section of the interior of the Schercytin is available for the installation or attachment of the fan or fans and for the air flow.
  • the shear cylinder 10 shown in FIG. 1 has a jacket 12 designed as a hollow cylinder 11 with a smooth outer jacket surface 13 and a smooth inner jacket surface 14.
  • knife-like shear spirals 16 fastened with end rings 44 and provided with baseboards 15 are fastened.
  • the shear spirals 16, as their name implies, run helically in the longitudinal direction of the shear cylinder 0.
  • the cylinder jacket 12 is equipped with a large number of air passage openings 17, which are designed as elongated holes in the exemplary embodiment.
  • a fan 22 is arranged in each of the end face regions 19 in the interior 21 of the shear cylinder 10, which in the exemplary embodiment according to FIG. 1 is designed as an axial fan designed like a propeller. As a result, it is equipped with a plurality of air blades or vanes 24.
  • the rotors of the two axial fans 23 are rotatably connected to the shear cylinder 10. They suck - with increasing speed of the shear cylinder 10 with increasing power - air from the outer environment of the shear cylinder 10 through the air passage openings 17 into the interior 21 and blow this air mixed with sheared particles out of the interior 21 of the shear cylinder 10.
  • an exhaust air pipe can be arranged on the shear cylinders.
  • the shear cylinder can also be connected directly to a dust separator into which the air is then blown directly by the fans 23.
  • the embodiment according to FIG. 2 does not differ in terms of the structural design of the shear cylinder 10 from that according to FIG. 1.
  • radial fans 25 are connected to the end face sections 19, the paddle wheels 26 at 27 being connected in a rotationally fixed manner to the shear cylinder 10 are.
  • the fan housing 28 leads into either a pipe or a dust collector.
  • Both exemplary embodiments have in common that a fan is arranged in (FIG. 1) or on (FIG. 2) each end region 19 of the shear cylinder 10.
  • the two fans of a shear cylinder then of course work in opposite directions, so that both of them act in the interior 21 of the shear cylinder 10 to generate negative pressure.
  • FIG. 3 schematically shows the mode of operation of a clipper equipped with a shear cylinder 10 according to the invention.
  • the shear cylinder 10 rotating in the direction of the arrow 29 interacts with a lower or counter knife 30 in the shear region 31.
  • the web 33 pointing with its fibers or its pile 32 in the direction of the Schzeug 12/18 is guided over a pointed table 34 as a web support 35 in the direction of the arrow 36.
  • a hollow table 37/38, having two table edges 37 and 38 spaced apart from one another, for a web 10 ′ is indicated as an alternative possibility of a web support with dash-dotted lines.
  • the shear cylinder 10 is surrounded by a nozzle box 39 at short intervals on all sides, the right side wall of which, with respect to the illustration, is provided by a part of a machine frame designated by 40.
  • the nozzle box 39 leaves only a narrow, essentially gap-shaped opening 41 directly in the area of the shear zone 31; otherwise it completely surrounds the outside of the shear cylinder 10. The result of this is that the vacuum generated in the interior 21 of the shear cylinder 10 in the direction of travel 36 exerts a suction behind the shear zone 31 on the pile 32 of the web 33, which is illustrated by the arrow array 42.
