Definitions

  • the present invention relates to a compacting device on a spinning machine for compacting a fiber structure in a following a pair of output rollers of a drafting compression zone, with a fiber strand through the compression zone transporting circulating air-permeable conveyor belt, associated with the compression zone, the conveyor belt along a portion of its circulation path leading suction tube, with a suction slot arranged in the suction tube and with a conveyor belt leading away from the suction pipe deflecting guide and a spacer of a compression device.
  • Generic compression devices are used for example on so-called elite ring spinning machines.
  • By compacting a fiber strand after stretching a sliver a compact yarn is produced.
  • the compacting of the fiber structure by means of the circulating, air-permeable conveyor belt, also called Siebriemchen, which is guided on a suction tube.
  • the suction tube contains a suction slot underneath the strainer, to which the fibers of the water bandage are sucked through the straps, but are prevented from sucking into the suction tube by the strainer.
  • the Siebriemchen transports the fibers from an output roller of a drafting to a pinch roller and from there to a spindle.
  • a deflection guide is arranged between the suction tube and the strapping.
  • the deflection guide for example, contain a groove in which the Siebriemchen is performed.
  • the sieve straps must be cleaned regularly, replaced when changing batches or exchanged after a few months for wear.
  • the suction tube and the deflection guide and several Siebriemchen arranged on it removed from the machine.
  • the assembly consisting of the suction tube, the deflection guide and several, arranged at a distance of the spindle pitch of the machine Siebriemchen is re-installed in the machine.
  • the object of the present invention is thus to facilitate the handling when installing and removing this unit and when changing the Siebriemchen and avoid damage to the Siebriemchen possible.
  • a compacting device on a spinning machine for compacting a fiber structure in a compression zone following a pair of output rollers of a drafting system has a circulating air-permeable conveyor belt or wire strapping transporting the fiber structure through the compacting zone.
  • the compression zone is assigned to the conveyor belt along a section of its circulation path leading intake manifold.
  • In the suction tube at least one suction slot is arranged.
  • the conveyor belt is guided by means of a deflecting guide arranged at a distance from the suction pipe.
  • a spacer is arranged between the suction tube and the deflection guide.
  • the spacer has a first clearance surface, with which the deflection guide is held at a distance from the suction tube, and in which the conveyor belt is tensioned.
  • the spacer is slidably held between the intake manifold and Umlenk Entry to disengage the first distance surface and to be able to change the distance between the intake manifold and Umlenk arrangement.
  • the distance between the suction pipe and deflection guide By changing the distance between the suction pipe and deflection guide, it is possible to keep the conveyor belt in operation tense.
  • the distance is reduced by means of the spacer between the suction pipe and deflection guide, whereby the conveyor belt is relaxed and thus can be easily deducted from the suction pipe and the deflection guide.
  • the spacer is easy to use and the conveyor belt can thereby be re-installed in a tensioned state in the spinning machine. A lateral displacement of the conveyor belt and damage to the conveyor belt or a malfunction of the conveyor belt is thus largely excluded.
  • the suction pipe and the deflection guide extend along several adjacent spinning stations of the spinning machine.
  • several conveyor belts can be removed, replaced and reinstalled at the same time.
  • the spacer is thus able to tension several conveyor belts at the same time or relax.
  • the spacer is preferably arranged next to a spinning station or between adjacent spinning stations. This ensures easy accessibility. In addition, the spacer does not interfere with the functionality of the conveyor belts at this point.
  • the spacer is designed such that it preferably has two spacer surfaces, wherein the first spacer surface holds the deflection guide at a distance to tension the conveyor belt and the preferably second distance surface the deflection guide at a distance to relax, in particular for disassembling the conveyor belt ,
  • the two spacer surfaces may be formed in several parts or in the form of a part, so that the spacer between the suction pipe and the deflection guide is easy to insert and thus can change the distance between the suction pipe and deflection guide.
  • the spacer can fulfill its main function, namely to prevent the conveyor belt from slipping off the intended position on the deflection guide, even with only the first spacing surface. But the second distance surface facilitates handling when the conveyor belt is to be released for removal.
  • the spacer is applied to change the distance to the suction pipe and the deflection guide. He spreads so to speak between the suction pipe and the deflection guide and in particular ensures that the conveyor belt is at least as tense that it remains in its intended position even when installing the entire unit.
  • the tensioning of the conveyor belt need not necessarily be so strong in all embodiments of the invention that the conveyor belt is already present in the voltage provided for the spinning process. It is sufficient if the sieve strap is stretched so far that it can keep its position during assembly.
  • the spacer is held on the suction tube, in particular in a groove of the suction tube.
  • a position on the suction pipe is fixed, on which it can be supported and reliably bring the deflection guide in a different distance from the suction pipe.
  • the spacer consists of several interacting parts, one or more of them may be provided for attachment in the groove.
  • the spacer has a slide, which is made in particular of plastic and further a ramp, which is in particular made of sheet metal.
  • a slide which is made in particular of plastic and further a ramp, which is in particular made of sheet metal.
  • the slide and / or the ramp have two depressions for latching in a predetermined position or catch.
  • Each of the recesses can ensure a defined distance between the intake manifold and deflection guide.
  • the two notches can be formed by means of a latching cam of the slide, over which the ramp is pushed. If the ramp has overcome the mountain of the locking cam, it locks in the valley. The two sides of the locking cam then each form a stable position of the ramp and thus provide for a first and a second position of the deflection guide.
  • the ramp has a clamping device for fastening in a groove of the suction tube, this makes it possible to easily attach the spacer to the suction tube.
  • the clamping device can dig in the groove of the suction tube and thus ensures a secure attachment of the spacer to the suction pipe.
  • both the slider and the ramp serve for a stop of the deflection guide in order to securely hold the deflection guide.
  • Slider and ramp can cooperate X-shaped, wherein the deflection guide rests on a leg of the slider and on another leg of the ramp.
  • the deflection guide has grooves or lateral edges, in i..., which the conveyor belt is guided. These grooves or guides corresponding to the spindle pitch of the spinning machine and thus ensure that the conveyor belt remains at the intended location.
  • the spacer is preferably designed so that the conveyor belt can be performed in the tensioned position in the corresponding groove of the deflection guide and in the relaxed position on the temporal edges of the guides can be performed in order to be replaced.
  • a spacer according to the invention of a compression device on a spinning machine serves to change a distance between a suction tube and a deflection guide leading a conveyor belt at a distance from the suction tube.
  • the spacer has at least a first, preferably also a second spacer surface and a sliding device.
  • the spacer is for use in a compactor as previously described. The spacer can be easily retrofitted and is thus able to facilitate the assembly or exchange of conveyor belts.
  • the spacer has a slider, in particular of plastic, and a ramp, in particular of sheet metal.
  • a slider in particular of plastic
  • a ramp in particular of sheet metal.
  • the slide and / or the ramp has at least one, preferably two, notches in order to be able to assume at least one, preferably two, detent positions, then the distance between suction tube and deflection guide is reliably maintained at two defined distances.
  • the assembly and disassembly of the conveyor belts can thus be done easily and without adjustment of the distance between the suction pipe and Umlenk arrangement.
  • the spacer can be very easily attached to the suction pipe and adjust the adjustment of the distance between the suction pipe and Umlenk entry.
  • FIG. 1 is a structural unit 1 with three compression devices 2 shown in plan view.
  • the assembly 1 is in operation, for example, incorporated in a spinning machine, as shown in the FIG. 1 of the DE 10 2013 107 353 is shown and described.
  • the assembly 1 has a suction tube 3 and a deflection guide 4, which are arranged parallel to each other.
  • a conveyor belt 5 is provided at each compression device 2 or at each spinning station, which is assigned to the compression device 2.
  • the conveyor belt 5 wraps around the suction tube 3 and the deflection guide 4.
  • the conveyor belt 5 is clamped by the suction tube 3 and the deflection guide 4 such that it can not get over the lateral guide 6 on the deflection guide 4.
  • Suction tube 3 and deflection guide 4 are connected to each other at their ends by means of a holder 7. The corresponding assembly 1 can thus be removed as a whole from the spinning machine or reinstalled.
  • each individual compression device can be designed as a structural unit 1 or more, for example, eight compression devices 2 can be connected in a structural unit 1.
  • two spacers 10 are arranged next to the outer compression means 2.
  • the spacers 10 ensure that the suction tube 3 and deflection guide 4 are at a smaller, relaxed distance or at a greater, strained distance from each other.
  • the conveyor belt 5 in the tensioned state, while in the smaller distance between the suction pipe 3 and deflection guide 4, the conveyor belt 5 is relaxed.
  • the endless conveyor belt 5 is not able to be pushed over the ribs 6 in the tensioned state, it is possible in the relaxed state, to push the conveyor belt 5 laterally over the shelves 6 and subtract from the suction tube 3 and the deflection guide 4.
  • To change the distance of the spacer 10 is moved in the double arrow direction P.
  • the deflection guide 4 enters a first or a second detent position on the spacer 10, in which the set distance is reliably preserved.
  • the holders 7 are designed such that the conveyor belts 5 can also be removed from the unit 1 via the holder 7. In this case, disassembly of the assembly 1, apart from the removal of the conveyor belts 5, not required.
  • FIG. 2 shows a plan view of a slider 11 of a spacer 10, which is preferably made of plastic.
  • the slider 11 has a first spacer surface 12 and a second spacer surface 13.
  • the first spacer surface 12 serves to keep the deflection guide 4 at a greater distance from the suction tube 3.
  • the second spacer surface 13 provides for a smaller distance between deflection guide 4 and suction tube 3.
  • the slider 11 also has on each side a side guide 14, which laterally of a locking cam 15 forms a first catch 15 and a second detent 16 to occupy two detent positions can.
  • a spring groove 17 is provided in each case.
  • the slider 11 acts with a ramp 21 according to FIG. 3 together.
  • the ramp 21 may be made of sheet metal, for example. On the one hand, it serves to define, lifted the deflection guide 4 at a greater distance on the first spacer surface 12 of the slider 11 or at a smaller distance from the suction tube 3 on the second spacer surface 13 of the slider 11 comes to rest.
  • the slider 11 is to be pushed through an opening 22 of the ramp 21. Side surfaces 23 of the opening 22 then interact with the side guides 14 of the slider 11.
  • the side surfaces 23 of the ramp 21 engage here after overcoming the locking cam either in the first detent 15 or in the second detent 16 of the side guide 14 of the slider 11 a.
  • the ramp 21 also has a tab 24, with which the spacer 11 can be attached to the intake manifold 3 as a whole.
  • FIG. 4 is a sectional view through a compression device 2 shown. It can be seen that the conveyor belt 5, the suction tube 3 and the deflection guide 4 encloses. The conveyor belt 5 rests on the smaller diameter of the deflection guide 4 and is laterally guided by the raised, a larger diameter having ribs 6. Not shown is a suction slot in the suction tube 3, which usually on the side facing away from the deflection guide 4 of the compression device 2 is arranged in the suction pipe 3. Also not shown is a suction device which generates negative pressure in the cavity of the suction tube 3.
  • the slider 11 of the spacer 10 holds in the position shown here, the deflection guide 4 at a greater distance from the suction pipe 3. As a result, the deflection guide 4 is held between the first spacer surface 12 of the slider 11 and the ramp 21.
  • the ramp 21 is arranged in the catch 16 of the slider 11.
  • FIG. 5 is the compression device 2 of FIG. 4 represented in which the deflection guide 4 at a smaller distance than in the FIG. 4 is removed from the suction tube 3.
  • the slider 11 has been displaced to the left in the plane of the drawing, as a result of which the deflection guide 4 comes to rest in the second spacing surface 13.
  • the deflection guide 4 is in turn stretched between the spacer surface 13 and the ramp 21.
  • the distance between the deflection guide 4 of the suction tube 3 is thereby so small that the conveyor belt 5 can be pushed over the rims 6 of the deflection guide 4 away. Threading out or replace the conveyor belt 5 is thereby possible.
  • the side surface 23 of the opening 22 in this case lies on the catch 15 of the slide eleventh
  • slider 11 and ramp 21 allows a change in distance between the suction pipe 3 and deflection guide 4, so that the conveyor belt 5 can be removed via the deflection guide 4.
  • a secure mounting of the compression device 2 and the assembly 1 in the Spinning machine possible.
  • a displacement of the conveyor belt 5 during assembly, by unintentional changing the distance between the suction pipe 3 and the deflection guide 4 is thus reliably avoided.
  • the suction tube 3 and the deflection guide 4 are held in each case in the end holders 7, which also can allow mounting in the spinning machine. But it is also possible that other holding devices are provided, which merely cause the position of the suction tube 3 and the deflection guide 4 and other means for fixing the assembly 1 are provided in the spinning machine.
