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.
- Figure 1 shows schematically a section of an open-end spinning device with an insertion funnel 1, a feed roller 2, one Feed trough 4 and an opening roller 3 attached to it, which is located in an opening roller housing 31.
- a fiber feed channel 32 which serves the dissolved fibers to a spinning element, not shown e.g. a rotor or a friction spinning device promote. Since these are well-known open-end spinning devices is here for a more detailed description waived.
- the insertion funnel 1 is in the feed trough 4, which move concentrically around the axis of the opening roller lets, for example with a clip or dovetail closure arranged positively. This connection can be detachable.
- the feed trough 4 is by a spring 42 on the one hand against the outer wall of an opening roller housing 31 pressed and on the other hand against the feed roller 2.
- the insertion funnel 1 protrudes with its attached loop catcher 11 the spinning device, the limitation of which is represented by line 61 should be out. This boundary line 61 marks at the same time the outer edge of the open-end spinning machine.
- the noose catcher 11 is primarily used on the sliver 9, which consists of a Sliver can is conveyed out, adhering second loops separate from the tape so that only the correct sliver cross-section can enter the spinning station.
- the noose catcher 11 itself can be made removable from the inlet funnel 1 and will be conveniently via a clip in the foot part 13 of the inlet funnel 1 clipped.
- the inlet funnel 1 has two, shown here in section, towards the nip the feeding device approximate walls 14 and 15 thereof greatest approximation at a constriction 16, that of the clamping line the clamping elements 2 and 4 is closest.
- the Spring 42 the feed trough 4 against the feed roller 2 and that Opening roller housing 31 presses, is supported in the housing of the spinning station from. 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.
- the injector 5 is expediently articulated in this way stored that he a small rotary movement of the food trough 4th can follow without between the funnel 1 and injector 5th Leaks can occur. 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.
- 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 sliver channel 8 is formed in that the two device parts, Seal the funnel 1 and injector 5 tightly.
- the sliver 9 passes through the constriction 16, between the feed roller 2 and the feed trough 4, so that the beginning of the sliver of the opening roller 3 presented for processing becomes.
- a nozzle 51 can be attached be.
- 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.
- FIG. 4 shows nozzle channels 522a and 522b, or their nozzles 52a and 52b, with nozzle channels 522a and 522b preferably are aligned so that their lines of action in cut the constriction 16 of the insertion funnel 1. 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.
- the transitions of the channel parts insertion opening 55 of the injector 5, channel 12 and channel wall 59 should be as possible be edgeless and smooth so that it doesn't have to Damage to the sliver 9 during insertion or flying of the individual parts of the device comes.
- FIG. 6 shows a further advantageous embodiment of the subject of the invention.
- An injector 5 is provided here, the one has another nozzle 53, which is not like the other two nozzles 52 and 51 opens directly into the sliver channel 8, but in a nozzle channel 177, which is in the upper wall 15 of the insertion funnel 1 is arranged and with a nozzle 178, which is just before the nip is between the feed roller 2 and the feed trough 4, flows.
- 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.
- This sliver feed can also be used on other slivers Machines such as Routes are provided, taking it it makes sense to provide a feed device here, which is capable of processing even the sliver continue to convey after the feeder the sliver presented and presented the feeder.
- the feed devices for the nozzles 51, 52 and 53 and others Arranged nozzles with the shown lines Compressed air supplied.
- the control of the timing of the injector nozzle flows is individually adjustable depending on the sliver.
- a control is expediently provided here, which it allows the nozzles and their To control the switching sequence. It makes sense that the invention Device also in electronically controlled maintenance machines integrated, before the start of a new sliver, or before the introduction of a sliver into a spinning station check for the presence of another sliver.
- a sliver can contained the sliver supply already exists at a spinning station, the one to be introduced Sliver end at a certain position from the jug hangs out or already using a known device was submitted to a fixing point at the spinning station. Furthermore a maintenance vehicle can remove an empty spinning can from the Remove the respective spinning position, a jug containing sliver bring it to the spinning position and then use this sliver feed the device according to the invention to the spinning device.
- the injector 5 or the (not shown) control device of the Nozzles of the injector 5 are expediently set so that an injection process takes about 1 second. This is cheap for the sliver, as not too long Currents act on the sliver and change it in this way, or damage so that it is no longer error-free from the feeder can be promoted.
- the nozzle 178 shown in FIG. 6 can interact with the Nozzle 53 of the injector 5 can of course also be used to create a Possibly missed clamping point by means of a short air blast to clean before the sliver 9 of the insertion opening 55 for insertion is presented.
- a gripper is advantageously used, which has two gripping elements, at least one of which is such is movably arranged that the gripper opened and to Gripping the sliver can be closed again.
- the two grippers as Rollers trained to support the insertion process rotate so that the sliver towards the spinning position is promoted.
- the conveying speed and the time of the The rollers run expediently with the nozzles controlling control.
- FIG. 7 shows an injector 5 in longitudinal section.
- nozzle 51 is against the side wall of the sliver insertion opening 55 directed that an air vortex arises, which twists and / or sharpens the sliver 9.
- Nozzle 51 is in this embodiment connected to the nozzle 62.
- Nozzle 62 supports due to its suction effect reaching into the sliver insertion opening 55 of threading the sliver 9 into the insertion funnel 1.
- Nozzle 52 can be controlled independently of this and can therefore be timed compressed air is subsequently applied to the nozzles 51 and 62. This is an optimal deflection of the sliver (9) in The direction of the constriction (16) of the insertion funnel 1 is reached.
- rollers 70, 71 In the sliver conveying direction are immediately in front of the injector 5 Rollers 70, 71 as an additional mechanical tape feed device arranged. These rollers 70, 71 capture the sliver 9 and convey it it by rotating it towards the injector 5. That Gripping the sliver 9 is the conical ends 701 Rollers 70, 71 relieved. The sliver 9 is threaded automatically into the corrugated rollers 70, 71 when it is in contact with the conical ends 701 of the rotating rollers 70, 71 reached.
- the speed of rotation of the rollers 70, 71 is advantageous such that it is compared to the delivery effect of the nozzles 51, 52, 62 slightly slows down the conveyance of the sliver 9. Thereby is achieved that the sliver 9 is always in a taut state through the loop catcher 12 or the constriction 16 of the insertion funnel 1 is funded. This prevents the sliver 9 clogged the channels 11, 16 to be traversed and thus would prevent safe threading into the feeding device.
- the rollers 70, 71 always ensure that a defined one Amount and thus weight of the sliver 9 is promoted. This is an adjustment of the nozzles 51, 52, 62 with respect to their Flow duration and intensity easier. Safe funding the sliver through the channels 11, 16 is thus ensured.
- a seal 63 is arranged on the upper edge of the injector 5. This seal 63 causes a tight connection between Injector 5 and inlet funnel 1 can be produced. In order to it is avoided that flow losses occur in the channels 8, 11.
- Figure 8 shows a front view of the injector 5 with the rollers 70, 71.
- the nozzle 51 is inclined to the center line of the Injector 5 arranged that it creates an air vortex that the Sliver prepared for threading into the narrow spaces.
- nozzle 51 by means of its air jet that the sliver 9 in Direction of the nozzle 52 is promoted.
- the nozzle 52 causes that Sliver 9 in the direction of the constriction 16 of the insertion funnel 1 is redirected.
- the sliver 9 is guided at this deflection point through the wall 59 of the injector 5.
- To bridge the Cross-sectional change between the wall 59 and the insertion funnel 1 are nozzles 60, 61 on the front of the injector 5 arranged.
- the nozzles 60, 61 are also in the direction of the Narrowed 16 of the insertion funnel 1 directed and cause that the sliver is tightened to the narrow point 16.
- the flow rate maintained despite the changed cross-section, without turbulence or significant loss of flow velocity occur.
- the constriction 16 becomes blocked by the sliver thus prevented.
- the nozzles 60, 61 ensure reliable conveyance of the sliver 9 guaranteed up to the feeding device.
- the rollers 70, 71 rotate in the direction of the injector 5 is the promotion of the sliver 9 through the air nozzles 51, 52, 60, 61 mechanically supported.
- It is sliver for passage cross-sections especially with narrow passage cross-sections and thick sliver advantageous if the rollers 70, 71 at one speed operated that the sliver 9 during the pneumatic Funding is always streamlined. This means that the rollers 70, 71 convey more slowly than the air nozzles 51, 52, 60, 61 would do this. This will block the bottlenecks the sliver 9 avoided.
- rollers 70, 71 are advantageously the same as the injector 5 arranged on a maintenance device. Rollers 70, 71 and injector 5 are therefore only the spinning machine or the spinning station delivered when sliver is conveyed through the bottlenecks and to be threaded into the spinning machine.
- the maintenance facility can either be directly on the spinning machine be arranged and for example along a variety of Spinning positions can be moved, or independently of the individual Spinning machine for example on one of several spinning machines operating automated transport system can be arranged.
- Injector 5 and rollers 70, 71 have proven to be advantageous to be arranged on a can transporter and therefore necessary for one can change at the spinning station the new sliver 9 insert into the spinning station.
- roller 70, 71 it is possible that the roller 70, 71 for gripping the sliver 9 can be removed from one another (70 ') and brought together again are. This is a safe and defined grip of the sliver 9 guaranteed.
- FIG. 9 shows a section through a top view of the injector 5 and the insertion funnel 1.
- the cross-sectional enlargement at the transition between the injector 5 and the insertion funnel 1 clearly recognizable.
- the sliver 9, the along the wall 59 from the injector 5 into the insertion funnel 1 would be deflected without the assistance of the nozzles 60, 61 be strongly swirled when entering the insertion funnel 1 and thus run the risk in the constriction 16 of the insertion funnel 1 to clog.
- the nozzles 60, 61 increase the flow rate in the larger cross section of the insertion funnel 1 and thereby cause a tightening of the sliver 9.
- the nozzles 60, 61 are arranged such that they are one Air flow parallel to the side walls of the insertion funnel Generate 1. An air cushion is formed, which is the friction of the sliver 9 reduced on the side walls.
- the nozzles 60, 61 can be omitted if the cross-sectional widening between injector 5 'and insertion funnel 1 is not very large. This can be done with a given insertion funnel 1 can be achieved in that 5 side elements on the injector are attached, which are introduced into the channel 8 and thus reducing the cross section. It is also possible to use the injector 5 with its wall 59 or the injector 1 already in this way to design that no major cross-sectional change takes place.
- FIG. 10 shows a sliver cutting device 80.
- a clamp 81 grips the sliver 9 on the injector 5 facing Side of the rollers 70, 71 and holds the sliver 9 firmly.
- a Clamping device 82 also grips the sliver 9 and moves after the clamping process in the direction of the arrow from the clamping device 81 away.
- the sliver 9 is between the clamping device 81 and 82 separately. Then the clamping device is released 81 from the sliver 9. It is thus a defined one Length of the sliver 9 from the rollers 70, 71 to the beginning of Sliver 9 made. This defined length makes a safe insertion of the sliver into the injector 5 or Insertion funnel 1 guaranteed.
- FIG. 11 shows an automatic maintenance device 90 on a spinning machine 91.
- the maintenance machine 90 runs on a rail along the Spinning machine 91. If a sliver 9 is to be introduced into the spinning station, The automatic walking machine 90 stops at this spinning position. The Sliver is gripped and the injector 5, which is on the walking machine 90 is arranged, supplied. The sliver 9 is then in the clamping point of the spinning station introduced.
- the invention is not based on the exemplary embodiments described limited.
