Definitions
- the invention relates to a method for filling a flake store and a flake storage device according to the preamble of claims 1 and 4.
- EP 0 731 194 A2 describes an exhaust air flap of a flake store for one Carding machine or a similar memory known to operate with fiber flakes is supplied from a pneumatic flock transport system.
- the shaft, or the storage unit separates the flakes from the transport air flow, which is the exhaust air is forwarded.
- a valve which includes a flap that is under its own weight assumes a predetermined rest position when there is no air through the Valve flows.
- filling chutes which in one of the following have outside screened side walls. Fiber flakes together with the transport air via a transport channel in the upper area the filling shafts promoted.
- the inlet of the individual filling shafts is from Filling shaft to filling shaft arranged higher, creating an even Distribution of the fiber flakes on the individual, one behind the other Chambers should be effected.
- An exhaust air duct is located approximately in the middle of the chambers arranged on the outside of the filling shafts.
- Each of the individual Chambers is connected to the exhaust air duct via a screen surface.
- DE 3734140 A1 describes a device for making the one more uniform Card, card, cleaner or the like.
- filling chute are arranged with which Actuators controlled for changing the air flow in the filling shaft become. This is intended to be uniform over the width of the filling shaft Filled with flakes.
- the disadvantage of this device is that a very great technical effort is required to ensure even distribution to cause the flakes, since measuring devices and adjusting devices required are.
- Another disadvantage is that the actuators Elements of the air-permeable wall pivoted out of their retention position , which means that additional funds must be earmarked with which the flakes of fiber that then emerge there can be caught.
- DE 19630018 describes a card in which a flake feed is used supplied fiber material in the form of flakes in a filling shaft is fed.
- the filling shaft includes an upper part, the feed shaft called, as well as a lower part of the shaft, called reserve shaft. Fiber flakes from the lower part of the shaft are separated by two conveyor rollers Cotton is discharged and passed on to the feed rollers of the card. Between the upper shaft section and the lower shaft section are located Feeding device which feeds flakes of fiber to an opening roller. It is in one of the exemplary embodiments, an air discharge system from the shaft outlines an instruction or a hint for a better distribution of the fiber flakes is not given here.
- the object of the present invention is therefore that shown Avoid disadvantages of the prior art and be structurally simple and without complex control technology or adjustment work Device for uniform feeding of filling shafts of a flake storage to accomplish.
- the object is achieved by a method for filling a Flake storage, in particular a card, card, cleaner or the like Fiber flakes loosened, the fiber flakes by means of a transport air stream be fed to a filling shaft of the flake storage.
- the fiber flakes are removed from the filling shaft at another point, whereby a separation of transport air flow and fiber flakes on an air-permeable Area takes place.
- the filling shaft is divided into several in its working width Areas divided. At least two valves are arranged on the filling shaft, the different areas are assigned, with a Valve when the level drops on the air-permeable surface to increase the level in this area opens, and a separation of Transport air flow and fiber flakes on the air-permeable surface of this Area takes place.
- a self-adjusting valve has the opposite to a driven valve Advantage that the valve without the action of an actuator depending on the Level in the respective area closes and opens. Such a valve reacts on the operating pressure or on the air flow. These parameters must change as a function of fill level.
- the invention also works with a driven valve very well.
- the valve remains fully open as long as the air flow openings between the filling shaft and the air discharge unit are not (partially) covered. simultaneously there is only a small difference between the pressure in the filling shaft and the pressure downstream of the valve. Both transport air and flakes flow therefore into the respective area of the flake storage.
- the speed of the upward movement depends not only on the filling level in their own area, but also from the filling levels of everyone else Areas. If all areas have the same fill level, they will all filled up quickly. If an area has a particularly low level it is filled particularly quickly.
- a generic flake store with the features of claim 4 causes according to the invention that the individual areas, in particular in a card, card, or cleaner essentially evenly be filled.
- the flake accumulator has a pneumatic feed from Fiber flakes, a shaft for collecting the fiber flakes and an exhaust unit in a side wall of the flake storage. In the exhaust unit the fiber flakes are separated from the transport air.
- the flake storage in its working width in several areas for storage the fiber flakes divided.
- There are at least two on the flake storage Valves are arranged, assigned to different areas, and each the areas have an exhaust unit.
- the side wall of each of these Areas has a stationary, air-permeable surface, in particular one Screen area.
- the exhaust air unit is arranged on the air-permeable surface. Due to the level in the area or at the air-permeable Area is influenced by the valve assigned to the area and thus the flake distribution equalized across the working width.
- the division of the flake storage into individual areas makes it easier possible to achieve a uniform filling level in the flake storage, because the individual area has a smaller width or length than the working width of the flake storage.
- the flakes are distributed over this shorter one Width of the individual area correspondingly more uniform.
- Each of the individual areas in the flake storage is an exhaust air unit assigned, so is the automatic regulation of the fill level in the individual Area in a simple way.
- About the exhaust unit is one more or less large amount of exhaust air is discharged from the individual area.
- the amount of air discharged depends on the amount of flakes to be supplied regulated. The more flakes to be fed into an area, the more More exhaust air is discharged from the area through the exhaust unit.
- the exhaust air unit is advantageously dependent on the air pressure in the actuated the respective area. Because of the level in relation to the sieve surface in the single area the air pressure in the single area is determined this size is suitable as a control variable for the exhaust air unit. The less the fill level, the greater the air pressure and the further the valve is in the exhaust unit is open.
- the exhaust air unit consists of a valve, which is moved by air pressure. So there are no other components necessary to move the valve, creating a very simple design is made possible.
- the exhaust air unit is advantageously above one in the flake store arranged intermediate resolution unit.
- the fiber flakes lie then the intermediate dissolving unit always in sufficient quantity.
- the valve advantageously has a valve flap arranged in the exhaust air unit, those due to the pressure conditions in the area assigned to them controls the exhaust air flow in the corresponding area.
- the amount of in the area fed fibers depends on the extent to which the screen area and so that the valve of the area is open or closed. Kick a bigger one Amount of transport air from this area, so takes place on the screen surface this area a separation of transport air and fiber flakes takes place. The separated fiber flakes remain in the area and cause an increase the level of this area. Is the sieve surface and thus the valve closed, the transport air is not through this area and that Valve directed into the exhaust air duct. This means that there is no separation of the transport air flow of the fiber flakes are made and therefore fiber flakes are not introduced in the corresponding area.
- the device according to the invention can be designed very easily and is therefore also very easy to maintain. After the valve is not in the immediate vicinity of the fiber flakes is arranged, the valve is contaminated by fiber flakes not possible. Special maintenance of the valve due to contamination is
- valve flap is designed such that it is closed Condition releases a small amount of exhaust air. This will make one quick control of the valve flap causes the existing exhaust air flow only needs to be increased in pressure to the valve flap in to move an open position. The valve flap can thus be activated more quickly, as if an exhaust air flow are first fed to the valve flap must, or a standing column of air must first be set in motion.
- valve flap by means of a Pivot bearing is rotatably mounted. Is the pivot bearing arranged so that the Valve flap generates a torque in its rest position due to its own weight, so that it is essentially closed, so there are no additional components, such as springs required to independently move the valve flap in bring a closed position.
- the valve flap is advantageously bent along its axis of rotation, so that it has two wing-like sections. It is also used in closed Condition causes a certain flow of exhaust air through the valve.
- the Sections of different sizes so is a balanced flow through the Valve allows.
- the smaller section can be used for a stop, which determines the maximum opening of the larger section his. It is also possible that the smaller section is dimensioned in such a way that a low flow also takes place in the closed state.
- at least one of the sections, in particular the section releasing the exhaust air flow is designed trapezoidal. This means lower flow losses to be expected when flowing through the valve.
- a kink has been found to be particularly advantageous proven with an angle between 10 ° and 30 °. This angular range has have proven to be particularly advantageous for rapid movement of the valve flap to enable even with a small pressure difference.
- the Unit is modularly attached to the area.
- the modules it is possible that they are prepared for assembly and with the appropriate valves are equipped and attached to the area in this condition.
- the modules on the side wall of one area and the adjacent arranged modular unit so are connectors in the exhaust air ducts to avoid, which additionally brings about the simplicity of the construction becomes.
- the modules are of two adjacent areas only with each other on the exhaust air duct connected.
- the relaxation rooms of two neighboring modules are separated from each other by a partition so that the on the valve flaps Exhaust air flows or overpressures in the neighboring areas do not act on the valve of the neighboring areas. So that becomes a incorrect filling of the areas avoided.
- the calming space is from the outside by means of a Door is accessible. This makes it possible to if necessary, clean. Whether cleaning is required can be assessed through an inspection window arranged in the door become. Only when it has been determined by the visual inspection that cleaning work then the door has to be opened and the flow process to interrupt in the area or to be influenced by the open door.
- the module in upper area of the flake storage can be arranged. This will the screen area due to an already high fill level of the fiber flakes in the area is not closed and the fiber flakes are thus still to feed the area.
- the recording volume of the individual areas is significantly increased.
- valve flap is arranged in the upper part of the module.
- a particularly great advantage of the invention is that one essentially Identical exhaust unit can be arranged in each area. In order to becomes an even distribution with respect to the width of the flake storage the fiber flakes causes. The single area is maximal with fiber flakes fillable.
- Figure 1 shows a flake storage 50 under construction.
- the flake store 50 fiber flakes 6 are fed via a feed 3 to a feed shaft 65.
- the feed takes place by means of a pneumatic transport air duct, which the fiber flakes 6 with a transport air flow from a machine, for example, feeds a mixer to the flake store 50.
- the fiber flakes 6 get through the feed 3 in the feed shaft 65 and there on an air-permeable surface, for example a sieve surface 10 separated from the transport air flow.
- the fiber flakes fall into the Feed shaft 65 and are accumulated at a certain level.
- the Fiber flakes are processed via an intermediate dissolving unit 60, which is below of the feed shaft 65 is arranged removed.
- the intermediate resolution unit 60 With the help of the intermediate resolution unit 60 becomes a homogeneous, uniform dissolution of the fiber flakes 6 guaranteed.
- the fiber flakes 6 thus dissolved are placed in the feed chute 66 promoted. From there, the fiber flakes 6 by means of a take-off unit 61 removed from the flake storage 50 and a machine, for example fed to a card as uniform cotton wool.
- the screen surface 10 In the area of the feed shaft 65, the screen surface 10 is in a side wall arranged. At this sieve surface 10, the fiber flakes 6 of their Transport air separated. The transport air escapes through the screen surface 10 in the calming room 13. In the calming room 13 there are turbulences and eliminates large flow differences in the transport air. From the relaxation room 13 the transport air flows through a in a side wall of the Calming chamber 13 arranged valve flap 14 in a connector 51st The transport air escapes from the connecting piece 51 as exhaust air into the exhaust air duct 5 and is transported there. Calming room 13, valve flap 14 and connector 51 form the exhaust unit 4.
- the exhaust unit 4 is here Embodiment assigned to the feed shaft 65. She can but can also alternatively or additionally be assigned to the feed chute 66.
- Figure 2 shows a partial section through the exhaust unit 4 of a flake storage 50 from Figure 1.
- the exhaust unit 4 is divided into two parts 4a and 4b. Thereby Areas 2a and 2b result in which transport air is discharged becomes.
- the areas 2a and 2b are separated from one another by means of a partition 11.
- the transport air flows depending on the pressure conditions more or less through the screen surfaces 10 in the calming space 13a or 13b.
- the transport air then flows through the valve flap 14a and / or 14b into the connector 51a and / or 51b. From the connector 51a and 51b, the transport air is discharged as exhaust air in the exhaust air duct 5.
- the exhaust air duct 5 can connect several flake stores with one another.
- the Valve flaps 14a and 14b are, as will be described in detail later, rotatably mounted. This is an independent adjustment of the opening of the Valve flap 14a and 14b guaranteed.
- the valve flap 14a and / or 14b is deflected and made possible the transport air flow entering the connector 51 a or 51 b.
- the valve flap 14a or 14b again rotated and essentially closes the opening assigned to it.
- each area 2a, 2b has a screen surface 10 and an exhaust unit 4a, 4b is assigned, that is that those stored in the areas 2a and 2b Fiber flakes are evenly distributed over the width of the flake store 50 become. This gives the advantage over the prior art, in which there is a risk that the fiber flakes unilaterally across the width be distributed and thus an uneven removal of the fiber flakes causes the feed shaft 65 or the feed shaft 66.
- FIG. 3 shows a section through the exhaust air duct 5 of a flake storage device 50.
- the individual exhaust units 4a, 4b are modules on the areas 2a, 2b arranged. On the one hand, they are connected to the side wall 9 of the flake store 50 and on the other hand connected to the neighboring exhaust unit.
- a Partition wall 11 only extends into the non-visible calming space 13 into it.
- the individual modules are continuous in the area of the exhaust air duct 5 connected with each other. This ensures that the exhaust air after it from the areas 2a, 2b and their calming rooms 13 through the valve flaps 14 has emerged, discharged via a common exhaust air duct 5 becomes.
- Each module of an exhaust air unit 4a, 4b is provided with a door 30.
- the door 30 is arranged below the exhaust air duct 5 and allows access to the Calming space 13 or the screen surface 10 arranged behind it it is possible to clean the screen surface 10. Cleaning can be done in such a way that the screen surface 10 is attached to the side wall 9 as a separate component is. For cleaning work, the component with the screen surface 10 is then removed from the Removed side wall 9, so that the screen surface 10 also on the in the feed shaft facing side can be cleaned. The cleaning can be done in addition, very easily take place outside of the flake store 50. In case of Damage to the screen surface 10 is also a problem-free replacement of the screen surface 10 possible with a new screen surface 10.
- an inspection window 31 is in the Door 30 provided.
- the transport air supplied in the feed channel 3 with the transported air Fiber flakes are fed to the areas 2a, 2b. If it is Allow pressure conditions in the area 2a, the transport air flow of the fiber flakes are not separated in the area 2a, but is further in the subsequent area 2b promoted and separated in area 2b.
- the Separation takes place, as already described above, in that the transport air enters the calming space 13 through the screen surface 10. It will continue conveyed through the valve flap 14 into the exhaust air duct 5 and out of the machine away.
- the flap 14 is arranged on each exhaust unit 4a, 4b. She points two sections 16 and 17. Along sections 16 and 17 is one Axis of rotation, which is caused by the pivot bearing 15, is provided. Around The flap 14 becomes the axis of rotation according to the pressure conditions in the Area 2a, 2b rotated more or less. The rotation causes an opening 19 in the wall 18 is opened more or less, causing more or less transport air than exhaust air leaves the individual area.
- the flake memory 50 can be expanded in a modular manner. Then it is ever if necessary, individual modules with further areas 2 and arranged thereon Exhaust units 4 can be used, whereby the flake storage 50 as required can be enlarged or divided into areas almost at will. For a finer distribution of the fiber flakes over the working width of the flake storage 50 can be provided that the individual areas are narrower be selected and arranged more than the two areas shown here become.
- Figure 4 shows a section IV-IV through an exhaust unit 4.
- the area 2 is in Flow direction of the fiber stream with a partition 11 of the subsequent area separated.
- the partition 11 has in the upper area an opening 12, which shows the area 2 shown in the flow direction subsequent area connects. Through this opening 12 it is Fiber flow possible to reach the areas behind. If it is Allow air and pressure conditions in the area 2 shown, the fiber air flow separated in this area.
- the transport air escapes through the Screen surface 10, which is provided in the side wall 9 of area 2.
- the Sieve surface 10 is designed such that the transport air through the sieve surface 10 can pass while the fibers and flakes of fiber on the screen surface 10 are held back.
- the transport air flow is after it has passed through the screen surface 10 in the calming room 13, which is designed such that turbulence of the transport air flow are largely eliminated.
- the transport air flows through the opening 19 in the wall 18 into the exhaust air duct 5.
- the valve flap 14 is shown in Figure 4 in the open state. This condition will ingested by the valve flap 14 when in the area 2 in relation to too few fiber flakes are filled in the other areas, i.e. if in the Area 2 the level is lower than in the other areas. In this In this case, the pressure conditions in area 2 cause the valve flap to rotate 14 in the position shown.
- the valve flap 14 is rotatably mounted in the pivot bearing 15. It has two Sections on. Section 16 is designed smaller than section 17. The Section 16 largely closes the above the pivot bearing 15 located part 20. The almost complete exhaust air is over the larger, lower part 21 of the opening 19 discharged into the exhaust duct 5. With another Increasing the pressure, it is possible that the valve flap 15 still opens further, so that the upper part 20 is opened. It is also possible to provide a stop that only has a maximum permissible opening the valve flap 14 allows. This causes only a maximum Volume that is determined by the cross section of the part then opened is can flow out of area 2.
- the valve flap 14 has a kink between the two wing-like sections 16 and 17, which has an angle of about 30 ° here. This Angle has proven itself for self-regulation of the valve flap 14.
- the lower section 17 has a trapezoidal shape on (see Figure 3).
- the flow conditions are favored because less Flow losses when redirecting the exhaust air flow from the calming room 13 arise in the exhaust duct 5. It is also through this Design the size of the maximum opening 19 in relation to the opening 12 optimally designed in the passage to the individual areas 2.
- Figure 5 shows the device of Figure 4, however, in the closed state the valve flap 14. Because of its own weight, the pressure at Transport air flow than in Figure 4, the valve flap 14 in the illustrated Position swiveled. Essentially, the lower part 21 of the opening 19 closed. However, a certain amount of the exhaust air flow is in the upper one Part 20 of the opening 19 ensured. This ensures that always one low flow from the area 2 through the sieve surface 10 into the calming space 13 and prevails through the opening 19 in the exhaust duct 5. A Increasing the pressure in area 2 thus causes rapid rotation the valve flap 14 and thus a rapid change in the flowable Opening 19, since the air column does not have to be moved first, but already moved and only needs to be strengthened. Otherwise, the Operation as already described in Figure 4.
- FIG. 6 shows a flake store 50 with a filling shaft 32 and a take-off roller 33.
- Filling chutes 32 of this type are, for example, for cards or Clutter provided.
- the filling shaft 32 is with a feed 3, which is above the areas 2a, 2b is arranged, via which fiber flakes the feed chute 32 are supplied. The fiber flakes are over an upper Opening from the feed 3 introduced into the filling shaft 32.
- At the bottom At the end of the flake store 50 there is a take-off roller 33, via which the fiber flakes from the filling shaft 32 at the removal opening there be removed.
- the filling shaft 32 has a partition 34, which separates the working width of the flake store 50 into two areas.
- Each of this resulting areas 2a and 2b is an exhaust unit 4a and 4b assigned.
- the exhaust unit 4a and 4b which in principle as in the previous exemplary embodiments is made up of a screen surface 10, which is a connection between the area 2a, 2b and the relaxation room 13 creates.
- the transport air flow is via this sieve surface 10 separated from the fiber flakes.
- the transport air flow gives way to the calming room 13 through the valve flap 14 into the exhaust air duct 5.
- the relaxation rooms 13 are also separated from one another by means of a partition 11, so that the pressure conditions arising in the individual area 2a, 2b for opening the valve flap 14 if necessary.
- FIG. 7 shows a section through a filling shaft 32 from FIG. 6.
- the fiber flakes which via the feed 3 in a pneumatic transport air flow delivered, fall in area 2a.
- the transport air flow itself is passed over the screen surface 10 into the calming space 13. From the relaxation room 13 it reaches the exhaust air duct via the opened valve flap 14 5 and is carried away from the machine.
- Area 2a is on yours a side surface with the partition 34 from the area not shown here 2b separated.
- the take-off roller 33 At the bottom of area 2a is the take-off roller 33 arranged.
- the fiber flakes from the Area 2a removed and fed to the textile machine arranged downstream.
- the invention is not limited to the embodiment shown here. So is the arrangement of the exhaust unit 4 is not necessarily in the upper part of the area 2 to arrange. It can also be set lower, so that the screen surface 10 closed at an appropriate level in the area early and the exhaust air flow is completely shut off.
- valve flap 14 it is also possible to close the valve flap differently than shown here shape.
- the feed is not parallel to the Working width of the flake storage takes place, but so that the individual areas are arranged side by side in relation to the feed.
