Definitions

  • the present invention relates to a method and an apparatus for introducing sliver into a spinning machine according to the preambles of claims 1 and 9.
  • a disadvantage of this known device is that on the sliver in the tubular suction opening due to the need Cross-sections have a relatively low suction power.
  • Cross-sections have a relatively low suction power.
  • there is a risk at the narrowest point of the compressor that by the air pressure acting on the sliver the compressor is clogged by the sliver and therefore not in everyone Case is ensured that the sliver from the compressor so far emerges that it was seized there by other devices will and can be further promoted.
  • the object of the present invention is now that described above To overcome disadvantages and a method and an apparatus to create that allow the feeding of sliver easy and safe to design in a spinning machine.

Only one spring 42 is shown in this example. Of course, several different attack points can also be used having springs are provided. It is also possible that Feed roller to move a pivot that is not in the axis of rotation the opening roller lies.
  • FIG 2 shows essentially the device described in Figure 1 however here is an injector 5 which is on the contact surface with the inlet funnel 1 with a seal to which Inlet funnel 1 created and already moved so that inlet funnel now 1 and the attached feed trough 4 from the feed roller 2 removed so that the clamping line between them both clamping elements is open.
  • the injector 5 was in this Position moved by a movement in the direction of arrow Z and applied to the insertion funnel 1. By pressing a contact surface 57 due to a thrust surface 17 of the inlet funnel 1 the movement of the injector 5 in the direction of the arrow Z the feed trough 4 pressed down and thus the clamping line open.

Will be after threading the sliver 9 the injector 5 in the direction of arrow E from the Spinning point moved away, so move due to the spring action the spring 42 the feed trough 4 and the insertion funnel attached to it 1 back up. The feed trough 4 then presses the sliver against the stationary feed roller 2.
  • the injector 5 is provided with a device, not shown, which e.g. an on of the OE spinning machine, a ground vehicle Spinning machine arranged maintenance machine or another Maintenance vehicle is led to the spinning station and against the Insertion funnel 1 moves in such a way that the feed trough 4 moves away from the feed roller 2 removed.

  • the positioning of the injector 5 on the inlet funnel 1 for example with the usual Positioning procedures like those for automatic maintenance machines at spinning positions are usual to perform.
  • Device to the injector 5 in the direction of arrow A. its insertion opening the beginning of the sliver 9 is presented.
  • the sliver Due to the suction effect of an air stream flowing through a line 522 from a compressed air source via a nozzle 52 into a sliver channel 8 is directed, the sliver is in the sliver channel 8 and further in the direction of an action line 523 of the air flow, which flows out of the nozzle 52.

  • the nozzle 52 is expediently so arranged to emit a flow in the channel 12 of the Loop catcher 11 acts in such a way that there is a slight vortex flow arises, which twists the beginning of the sliver 9, in a way that you twist a thread end with your fingers, to make it a bit more narrow and to narrow it down lead through.
  • FIG. 3 shows a top view of the injector 5 at 59 designated line, the inner wall of the "channel half" of the channel 8, by joining the parts injector and insertion funnel is formed. It is also the symmetrical one in FIG Arrangement of the nozzle channel 522 and the nozzle 52 can be seen.

It is here furthermore the arrangement of a nozzle channel 511 and the nozzle 51 recognizable.
  • Figure 5 shows the front view of the injector 5, the lower Part of it can be seen very well that a sliver insertion opening 55 is designed such that it essentially upwards extends conically so that its cross section at the transition point approximately in the loop catcher 11 of the insertion funnel 1 is as large as the cross section of the channel 12 of the loop catcher. So it is when the injector is properly positioned 5 to the insertion funnel 1 or its loop catcher 11 a wall 58 in the wall of the channel 12 of the loop catcher 11 pass and in the further course of the channel 8 into a wall 59 of the injector 5.

  • This third nozzle 53 is useful, for example, when processing sliver materials that are due to their weight or their friction behavior not so easy in have the insertion funnel 1 inserted.
  • the conveying air flow for the sliver 9 in the direction of the nip supports the spinning device, characterized in that by means of air flowing through the nozzle 178 at the constriction 16 a negative pressure is created, which causes the sliver 9 or Beginning of the sliver 9 is easier through the constriction 16 Clamping point, or between the clamping elements of the spinning device emotional.
  • the feeding of the sliver 9 can also are supported by the fact that the sliver is from a device 9 so far (from a spinning can, for example) is so that the device according to the invention only the sliver length, which is inserted into the spinning station must lift.
  • the feeder can for example be designed as an apron drafting system be.
  • the spinning device can be a friction or Air spinning device or more generally a spinning device be working with an open end or with dissolved fibers.
