Definitions

  • the invention relates to a dust protection system on a winding machine, in particular on a warping or warping machine, with which the threads of bobbins can be pulled off, in particular, from a creel and wound as a thread group on a winding tree, with a vertically arranged inside a building parallel to the winding tree, the Entire front behind the machine shielding against drafts shielding wall, which is provided with a protective screen shielding a machine operator station against drafts, and with an air suction device arranged in front of the shielding wall and above the winding machine on the draft side.
  • a dust protection system with the aforementioned features is known from DE-A-38 43 608.
  • the shielding wall of the known system extends from the building ceiling to the floor on which the system is built.
  • the machine operator station is arranged between this shielding wall and the winding machine. Since the operator would consequently be hit completely by the air flow generated by the winding machine, the windshield connected to the shielding wall is arranged vertically above the axis of the winding tree.
  • the air suction device arranged above the winding machine consists of a suction funnel which is connected to an air conveying device via a pipe system is extracted with the extracted air back into the room through a filter. The protective effect achieved by this dust protection system can be improved.
  • the dust extraction by the known air extraction device can only remove a small part of the total dust.
  • the much larger remainder is distributed in the vicinity of the system, for example by using blowing devices to keep dust-critical points clean, for example on the creel and / or by air movements within the building.
  • the invention is therefore based on the object of improving a dust protection system with the features mentioned at the outset so that the entire environment of the winding system can be kept dust-free with the air suction device arranged above the winding machine.
  • This object is achieved in that arranged over the entire length of the winding machine, its thread sheet and the bobbins arranged inside the building, the air flow generated by the thread sheet to the air suction device channeling side and ceiling walls are available.
  • the suction effect can be improved by avoiding secondary air.
  • a structural simplification is achieved in that the protective screen is installed flush in the shielding wall, which separates the machine operator station from the winding machine and that the shielding wall has a control panel if necessary.
  • the protective pane can be a prefabricated component of the shielding wall. It is also important, however, that the machine operator station be hermetically sealed against the winding machine.
  • the shielding wall is a safety element because it prevents accidental contact with the winding machine that is in operation. Intervention in the winding process is not prevented, however, if a control panel is present outside the shielding walls, which control panel is expediently provided on the shielding wall.
  • the system is designed in such a way that the shielding wall can be moved from the shielding position into a position that enables direct operation of the winding machine from the operator station.
  • This mobility is achieved in that a controllable mechanical lifting device is provided for moving the shielding wall guided laterally in its plane.
  • the air inlet opening formed by the side and ceiling walls on the coil side is wall-free.
  • the system is designed so that the side walls are provided with access doors and / or have a coil carriage next to the creel allow to move distance.
  • An advantageous embodiment of the system is provided if the ceiling wall is provided with a suction opening adjacent to the winding machine, to which the air suction device formed outside the suction channel formed by the side and ceiling walls is connected.
  • the entire air extraction device is arranged outside the walls surrounding the system, so that the space requirement is correspondingly less.
  • accessibility is correspondingly better.
  • the air suction device can be designed independently of the design of the ducting of the air flow.
  • the side and / or ceiling walls from the creel to the winding machine are approximately parallel to the adjacent threads of the thread family. This adjusts the flow of air to the spatial conditions of the system. Dead spaces impairing the effects of the air suction device are avoided and the air suction device requires a correspondingly lower output.
  • the side and / or ceiling walls are provided with air inlet nozzles. These air nozzles are either passive, that is, they serve to draw in side air under the action of the air extraction device, or they are active by blowing in air.
  • the winding system shown in FIGS. 1, 2 essentially consists of a winding machine 10 with a machine-driven winding tree 15, which pulls the threads 11 as a group of threads 14 from spools 12 of a creel 32 and winds them up.
  • the thread sheet runs through a thread guide reed 37 for the orderly feeding of the threads 11. From this guide reed 37, the threads run around a guide roller 38 to the run-up point 39, where a pressure roller 40 acts to compress the winding 41.
  • Dust accumulates when the threads are wound.
  • the bobbins 12 are dusty, the threads 11 rub against deflection and braking points of the creel 32 and they are also stressed in the area of the winding machine 10, namely on the thread guide 37, on the guide roller 38 and during the winding itself by the pressure roller 40. All of them Movements of the system associated with the winding process lead to air movements which in turn swirl the dust. As a result, there is a dust protection system that prevents the dust from spreading uncontrollably.
  • On the front side 17 of the machine there is a shielding wall 19 which, according to FIG. 2, extends over the entire width of the winding machine 10 and beyond.
  • the shielding wall 19 separates a machine operator station 20 from the winding system, so that the operator 42 is completely protected against drafts 18.
  • the shielding wall 19 has one Protective pane 21 through which the operator 42 can observe the winding process. Manual access is denied to the operator 42 when the shielding wall 19 assumes the position shown in solid lines. However, there is a control panel 43 by means of which the operator 42 can influence the winding process.
  • the operator 42 gains manual access to the winding machine 10 by removing the shield 19 from the range of motion of the operator 42. This is achieved, for example, by a lifting movement taking place in the plane of the wall 19, with which the shielding wall 19 is lifted vertically and reaches position 27.
  • the lifting takes place with the lifting device 28, which consists, for example, of a motorized winding device for a rope acting on the shielding wall 19.
  • the lifting device 28 is itself fastened to a ceiling 50 of the building 16 via a fastening device 44.
  • U-shaped guide strips 45 for example, provide lateral guidance of the wall 19 when raised.
  • Side walls 24 and a top wall 25 extend over the entire length L of the winding installation and form an air access opening 29 at the end of the winding gate 32 facing away from the winding machine 10, which is wall-free, so that the entry of air 46 is unhindered.
  • the side walls 24 are at a sufficient distance A from the creel 32 so that the operator 42 can move in the space 47 formed thereby, for example in order to attach full coils 12. In any case, the distance A is so large that a bobbin carriage 31 can also be used, with which full bobbins are transported to the bobbin creel 32 or brought into the unwinding position.
  • access doors 30 are provided in the side walls 24, for example at the level of the creel 23 or at the level of the thread sheet 14.
  • the side walls 24 run approximately parallel to the adjacent threads 11w of the thread sheet between the creel 32 and the winding machine 10, so that there is a reduction of the distance of the side walls 24 from the creel 32 to the winding machine 10, provided that it is shorter than the creel 32 wide. In any case, it is achieved that the channeling of the air 46 flowing into the space between the walls 24, 25 is favored.
  • the space between the walls 24, 25 is kept as small as possible.
  • the walls 24 On the shielding wall side, the walls 24 have U-shaped guide strips 45 for the shielding wall 19.
  • the top wall 25 is also adapted between the creel 32 and the winding machine 10 to the course of the thread sheet 14 in order to keep the cross section of the sewerage space as small as possible.
  • FIGS. 1, 2 show that air inlet nozzles 34 are present in the side walls 24, which is symbolized by the arrows 48. Accordingly, air may enter that is entrained between walls 24, 25 due to the jet effect of air flow 23, or a blower may be used to blow in the side air. Such air inlet nozzles 34 can also be present in the top wall 25.
  • suction opening 33 In the area of the winding machine 10 there is a suction opening 33 in the ceiling wall 25 which, as shown, extends over the entire width of the winding machine. Their exact dimensioning is to be adapted to the actual spatial conditions, as well as to the effect of the air flow 23 and to any air guiding devices present within the air duct.
  • the air outlet or suction opening 33 leads into a suction device 22 formed from air lines 35, in which, for example, a dust filter 36 and a blower 49 are arranged. With the aid of the blower 49, the air is sucked through the filter 36 and conveyed back cleaned into the building 16.
