Definitions
- the invention relates to a flock storage and a flock feed according Oberr concept of claims 1 and 19.
- the way in which a card is fed with fiber material has a significant influence on the card sliver produced. Irregularities in the feeding of the carding machine are expressed in the formation of thick or thin areas in the produced sliver. These defects in the strip can only be partially corrected in the subsequent further processing of the fibers up to the finished yarn. They therefore have a direct influence on the final yarn quality.
- the fiber flakes in the hopper must form a uniform cotton wool. Ie. The fiber flakes must be distributed evenly over the entire width of the hopper to thereby form a homogeneous wadding of uniform density. The fiber flakes are fed pneumatically to the filling shafts.
- the feeding of the carding machines with the aid of a pneumatic fluff feed does not, however, guarantee a sufficiently uniform feed of the carding machine or of the associated filling chute.
- This problem has long been known and has been solved in that the filling shaft of the card was equipped with a feed device, which divided the actual hopper into two superimposed manholes (top and bottom shaft). Thanks to the feeding device, the fiber flakes move evenly from the upper shaft into the lower shaft, regardless of the uniformity of the delivery of the flakes, when the filling shaft is fed with fiber flakes via the pneumatic fluff feed. This results in the lower part of the filling shaft, a homogeneous Wattenvorlage, which is suitable for feeding the card.
- Flake reservoirs which are formed from an upper and a lower shaft part, represent a well-known state of the art in spinning plants. Examples of such reservoirs can be taken from the following patents: US 4499633; US 4593436; US 4656694; US 4697309; US 4731909; US 4776066; US 4968188; DE 2939968; DE 3904853; DE 3904878; EP894878.
- Such Flocken agenda are today usually provided with a feed roller, which is provided between the shaft parts and the template passes in the upper part of the shaft from an opener or opening roller. The at least partially dissolved flakes are passed from the opener roller to the lower shaft part.
- the lower shaft part is normally arranged substantially vertically, wherein a horizontal arrangement z. As proposed in DE-C-3928280.
- EP-B-866153 and / or EP-A-989213 In the period before 2020 it is unlikely that a carding machine for the spinning mill will have a working width> 2m.
- the carding of a spinning works but with several cards, which must therefore be produced as inexpensively.
- These machines are designed to process cotton. They are therefore normally used as traveling Ckel-cards executed in order to fulfill a Schmutzausscheidungsfunktion.
- the present invention relates to a filling shaft for the carding of a spinning plant, d. H. a plant designed for the production of yarn.
- the carding machine supplied from the hopper must produce a sliver that is suitable for further processing into a yarn.
- the terms "carding” and “spinning” are accordingly limited here - "carding” for the production of nonwovens are excluded
- it is not always easy to determine from the patent literature whether the stated hopper constructions are really suitable for yarn production and / or for the Nonwoven production are suitable - many design principles are generally claimed (these remarks are also valid for different examples in the previous chapter).
- the invention is based on a filling shaft or a "flock storage" according to DE-A-19906148.
- DE-A-19906148 a filling shaft or a "flock storage" according to DE-A-19906148.
- DE-A-19906148 thus describes a card with a proposed reserve shaft, which is fed from above with finely dissolved fiber material.
- a proposed reserve shaft In the wall of the reserve shaft, there is an air-permeable surface with air outlet openings.
- the upper limit of the deposited flock column in the reserve shaft is located in the area of this air-permeable surface.
- the invention according to DE-A-19906148 provides a further air-permeable surface which lies outside, in particular above, the air-permeable surface assigned to the deposited flakes.
- This prior arrangement allows the subdivision of the exhaust air area into two chambers whose air outlet openings (air outlets) are independently adjustable. By integrating the additional air outlet surfaces in the shaft area of the subsequent flocculation (apparently down into the reserve shaft) to be supported by gravity.
- the lower end of the reserve shaft is completed in the example according to DE-A-19906148 by a feed roller, which cooperates with a catchment trough.
- This feed roller turns the reserve shaft into the fiber material of one of them below. supplied with pins or sawtooth wire high-speed opener roller, which communicates on a part of its circumference with a lower feed duct.
- this feed shaft has been shortened to compensate for the increase in the reserve shaft - but nothing is said in the DE-writing and the measure could, in the opinion of the Applicant, merely further disadvantages.
- the object of the present invention is therefore to allow an improvement in the technological side effects of the reserve shaft, d. H. its effect on the end product of the flake storage, namely the wadding prepared as a template for the carding machine.
- the invention provides several advantages, such as:
- the fiber flakes are normally conveyed by means of a transport air stream fed to a hopper of the flake storage.
- the fiber flakes are removed from the hopper at another location, with a separation of transport air flow and fiber flakes takes place on an air-permeable surface.
- the hopper can be subdivided in its working width into a plurality, at most only mentally defined, areas.
- At the filling shaft are then preferably at least two valves, preferably one flap arranged, which are assigned to different areas, wherein a valve when lowering the level 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.
- This area of the hopper is thereby fed more fiber flakes.
- the valve closes again to reduce the filling level in this area, and this area of the filling shaft is thus supplied with less fiber flakes.
- the level settles as well, so that the level in the individual areas is maintained at substantially the same level.
- This old proposal is not essential to the present invention but may be advantageously combined with the new proposal.

- the fiber flakes 6 pass through the feed 3 into the reserve shaft 65 and are there separated on an air-permeable surface, for example a screen surface 10 of the transport air stream.
- the fiber flakes fall into the reserve shaft 65 and are accumulated at a certain filling level.
- the fiber flakes are removed via an opening module 60, which is arranged below the reserve shaft 65. With the help of the module 60 a homogeneous uniform resolution of the fiber flakes 6 is ensured.
- the thus dissolved fiber flakes 6 are conveyed into the feed chute 66. From there, the fiber flakes 6 are removed by means of a take-off unit 61 from the flock storage 50 and fed to a card as a uniform wadding.
- the screen surface 10 is arranged in a side wall. At this screen surface 10, the fiber flakes 6 are separated from their transport air.
- the transport air escapes through the screen surface 10 into the settling chamber 13. In the settling chamber 13 turbulences and strong flow differences of the transport air are eliminated. From the calming space 13, the transport air flows through a valve flap 14 arranged in a side wall of the settling chamber 13 into a connecting piece 51. From the connecting piece 51, the transport air escapes as exhaust air into the exhaust air duct 5 and is transported away there. Calming chamber 13, valve flap 14 and connecting piece 51 form the exhaust air unit 4.
- FIG. 2 shows a partial section through the exhaust air unit 4 of a flock accumulator 50 from FIG. 1.

- the valve flap 14 is shown in Figure 4 in the open state.
- FIG. 5 shows the device of FIG. 4, however, in the closed state of the valve flap. By its own weight, the valve flap is pivoted into the illustrated position at a lower pressure of the transport air flow than in FIG. In this case, the lower part 21 of the opening 19 is substantially closed. However, a certain amount of the exhaust air flow is ensured in the upper part 20 of the opening 19.

- the reserve shaft 32 is provided with a feed 3, which is arranged above the regions 2a, 2b, via which fiber flakes are supplied to the reserve shaft 32. The fiber flakes are introduced into the shaft 32 via an upper opening from the feed 3.
- the reserve shaft 32 has in this example a partition wall 34, which separates the working width of the storage space 50 into two areas. Each of these resulting regions 2a and 2b is associated with an exhaust air unit 4a and 4b. However, this partition should possibly be omitted. It usually proves to be superfluous even with a working width of> 1m (eg approx.

- the axis of the take-off roll (feed roll) 33 is indicated by A in Fig. 9, and the line UE indicates a "lower” horizontal plane containing the axis A.
- the line OE indicates an "upper" horizontal plane , which contains the uppermost edge of the reserve shaft 32, where the shaft adjoins the flock feed channel, which forms part of the feeder 3.
- the height difference H between plane OE and plane UE according to this invention is at least 900 mm and preferably 1000 to 1200 mm.
- FIG. 10 shows further features that may help to solve the aforementioned problems.
- a further line points to an e-plane which contains the horizontal inner surface of the flock feeding channel, wherein the height difference with respect to the plane OE is indicated by KH (channel height).
- KH channel height
- This height can also be chosen with advantage a little larger than this was the case so far, z. B.> 550mm and preferably about 600 to 650mm.
- the width B of the channel can also with advantage> 130mm, z. B. about 140 to 150mm are selected.
- the total height of the flock storage together with feed, measured from the bottom, is indicated in FIG. 10 by GH, the bottom on which the storage and the carding machine supplied by it with cotton are not shown in this figure.
- the total height of a flock storage according to the invention may be> 3.50m, e.g. B. 3.70 to 3.90m.
- a reserve shaft according to FIG. 9 or 10 is preferably combined with an opener module, as it is in principle in the preceding patent application WO 2005/087994 (see Fig. 8 of the present application). To clarify certain elements of this arrangement will be explained in more detail with reference to Figure 11, wherein the new arrangement with the preceding arrangement according to EP-A-894878, in particular Figure 3 of the latter application, is compared below.
- reference numeral 3A denotes the feed in the form of a bottle transport channel and reference numeral 65A denotes the reserve slot of a flake store according to the invention.
- the reserve shaft 65A comprises two walls 90 and 92, respectively, which extend over the entire working width of the shaft.
- the reference numeral 100 indicates an air collecting space which is connected to an exhaust air duct (not shown, see channel 5 in the other figures).
- the collecting space 100 can be formed according to known principles and is therefore indicated only schematically in FIG.
- the collecting space 100 is bounded by a part of the wall 90, which is provided with a perforation (not shown), so that this wall part is permeable to air.
- the transport air which is supplied via the feed 3A, thereby separates from the entrained flakes in the upper part of the reserve shaft, that it passes via the perforation into the collecting space 100 and into the exhaust air duct (eg into the channel 5, Fig 10) while the flocs are retained in the reserve shaft 65A.
