Disclose in DE4323472C2 and a kind ofly be used for bunchy or compression (compacting) and finish the method for the fiber strip of drawing-off at double small belt-type drafter, fiber strip is concentrated in together and is twisted into yarn in a fiber bunchy district after drawing-off.This moment, fiber strip was that the conveying mechanism of belt lace of the perforate of disturbing property without a head is supported on a side by form by means of suction air flow during gathering.
The device that is used to implement this method has adjustable supporting mechanism, can regulate the position of the belt lace of the perforate clamping part right with respect to the front draft roller of drafter by means of it.The gradient of the belt lace support by changing belt lace and guiding belt lace is regulated itself and the right spacing of front draft roller and height and position and the beginning compressed of setting thus.
In addition, realize such effect by this supporting mechanism, promptly when interrupting by the suction force of belt lace, but drafted and compression fiber strip that also do not reinforce by twisting can not fall down from the belt lace of perforate and cause broken yarn.When breaking down when machine stops or when keeping suction force, this situation takes place.This broken yarn must be got rid of by hand.Especially when it frequently occurs, can constitute the workload that to accept to operating personnel.
Another advantage of supporting mechanism is, it is controlled the ostium path of air by cover plate and reduces energy consumption in the delivery area thus.Since proved compression basically only at fiber strip and then from carrying roller to after coming out and also still implementing the compressional zone before the belt lace of perforate and its inlet between the area of coverage, so compression is not subjected to preferably or fully not disturbed by it of cover plate.
For the belt lace that guarantees perforate pastes volt reliably on suction shoe, proved advantageously, the belt lace of perforate is not point-blank but a little fully is directed.This moment, obviously the profile of bracing or strutting arrangement will be complementary with this guiding device of belt lace.
The task that the present invention is proposed is, provide a kind of useful easy coupling and favourable form of implementation aspect as much as possible for this reason.The present invention is by solving this task in the feature described in the main claim.
Can pass on the type rail and fixing different propclip, it has the upper surface of the belt lace that supports differently contoured perforate.The quantity of propclip and mutual interval (spacing) form of implementation direct and double small belt-type drafter is complementary, and especially is complementary with drafter carriage and spacing of station quantity and station.The propclip that damages can be changed at an easy rate.By plastic injection-moulded or in pressure casting method, be very favorable by the propclip of metal manufacturing; It can be made at low cost.They can be laid in different sizes and form of implementation, and can not cause high warehousing costs.
The support that also discloses the belt lace that is used to guide perforate in beginning in the described document disposes the groove that matches with the hole, and slide block has been installed in the both sides of groove, its upper support belt lace.Show, except advantageously arranging the slide block that is used to support belt lace on the belt lace support or on can also surface other locational slide block at propclip.
In order not disturb or not influence compression process nocuously, propclip can be limited on the Background Region of the upper surface that is positioned at propclip from looking up to the supporting role of the belt lace of perforate or be limited on the slide block that is arranged on the side, path, hole by the side.
In the figure of accompanying drawing, show some embodiments of the present invention simplifiedly.
Fig. 1 is the viewgraph of cross-section by the compressional zone of drafter,
Fig. 2 and Fig. 3 have shown the vertical view of the type rail with two heteroid propclips, wherein only with dashed lines signal of the operation of belt lace.
The front draft roller that figure 1 illustrates a drafter is to 1,2, and its fiber strip that tractive is intact is exported to fiber bundling device or fiber compressing apparatus.This device comprises another roller to 3,4, and its top roller 4 is reeled by the belt lace 5 with hole 6 on each station.This belt lace is directed in the support 7 that schematically illustrates, and this support can be tumbled around the axis 8 of top roller 4.Roller is configured to suction shoe to 1,2 part medium-height trestle and has the pump orifice 10 that the belt lace facing to perforate opens wide there at stent cover, it is connected with the head tank that is not shown specifically by pipeline 11.
The front draft roller to 1/2 and the roller of the compression unit zone between to 3/4 by from the output line of the fiber strip of front draft roller 1 down and the compressional zone 18 between the belt lace reach the upper surface 15 of a propclip 13 at belt lace 5 before constitute.Only in this compressional zone, carry out the compression of fiber strip.What be connected with this compressional zone 18 is delivery area 19, and compressed fiber strip is fed to the roller of compression unit to 3/4 in this delivery area.This roller stops constituting the twisting of propagating twisting in the subtend compressional zone 19, and this twisting is that the spindle by postposition applies to fiber strip.The extension of fiber strip is by chain-dotted line 20 signals.
Arrange that between bottom roll 1 and 3 cross section is the type rail 12 of rectangle, it extends between two carriages of two drafters.It can change by the distance piece that the governor motion that do not illustrate such as adjustment screw maybe can be inserted herein with respect to the height and position on drafter plane.Propclip 13 can move on this type rail and can by means of counter-sunk screw from below fixing.Each station of drafter all disposes a propclip.
The upper surface 15 of support member 13 can be flat.Because belt lace 5 is not the straight line guiding usually below the suction shoe 9 of bending, the upper surface 15 of support member 13 also correspondingly wants crooked thus.This bending in an advantageous manner always the guide surface of the belt lace below suction shoe 5 adapt.It also can be favourable that but other shape is used for the upper surface 15 of support member 13.For example can recommend a kind of shape, wherein the support of belt lace 5 concentrates in its Background Region in the fiber bunchy district.
The effect that also has of support slipper 16 is to restrain air from side, axially enter the via path in addition.This further reduced the air consumption of device and advantageously entering of air concentrated on along the fiber movement direction by the zone after the compressional zone radially or tangential mobile in.Should be appreciated that this slide block is except being arranged on the upper surface 15 of support member 13 on the suction shoe 9.
But usually, the support pressure of suction shoe 9 on belt lace 5 is in this wise little, so that like that also can be from the side arrangement in the perforate path 6 of belt lace on the upper surface 15 of support member 13 among this support slipper 17 embodiment as shown in FIG. 3.This moment, belt lace 5 was supported on this slide block 17.And restrain air along axially entering the perforate path by this slide block.
Generally, therefore can determine, the front draft roller to 1/2 and the roller of the compression unit zone between to 3/4 by from the output line of the fiber strip of front draft roller 1 down with reach at belt lace 5 that the compressional zone 18 between the belt lace constitutes before the upper surface 15 of a propclip 13.Only in this compressional zone, carry out the compression of fiber strip.What be connected with this compressional zone 18 is delivery area 19, and compressed fiber strip is fed to the roller of compression unit to 3/4 in this delivery area.The twisting that this roller is propagated the twisting that constitutes in the subtend compressional zone 19 stops, and this twisting is that the spindle by postposition applies to fiber strip.
