Description

The invention relates to a belt washing method and a belt washing device for washing a textile belt, of textile belts or textile strand formations. Examples of textile strand structures are: braids, knitted fabrics, knits, scrims, nonwovens, so-called nonwovens, rovings, yarns. Both single-ended and multi-end systems should be included.

For example DE 10 2007 003 569 A1 Textile tapes are washed in a washbasin, first a feeder feeding the tape or the parallel tapes into the washbasin and in the washbasin a deflection roller takes over the tape or the parallel tapes, as determined in the preambles of claims 1 and 2.

The invention is based on the problem that washing processes must be further improved in order to be able to treat textile belts more economically and / or with a better qualitative result.

This problem is solved by a band washing method and a band washing apparatus according to claims 1 and 2 comprising the respective characterizing part.

Advantageous embodiments are specified in the respective subclaims.

The strip washing method according to the invention for washing a textile strip, textile strips or textile strand formations in a sink ( 4 ) includes the already known method steps supplying the tape or the parallel bands in the sink and deflecting the tape or the parallel bands in the sink by means of a deflection roller. The invention proposes to clean the band or the parallel bands by means of at least one washing roller arranged in the wash basin. The washing roller has for this purpose at least one fluid-permeable outer wall. Is then or according to the invention, the tape or tapes are beaten around the outer wall of the washing roller to at least partially rotate around the same during the washing process, it allows the invention that a washing liquid is conveyed through the belt or the parallel belts.

According to an advantageous embodiment, the washing roller further comprises at least one inside the outer wall and more preferably coaxially to the outer wall, rotatable independently of the outer wall of the pulsation roller. According to a further advantageous embodiment, the pulsation roller has at least one blade along its outer circumferential surface, ie facing the outer wall in the mounted state. The blade or another type of pulsation-inducing geometric configuration are arranged facing the outer wall in order to convey a washing liquid or a treatment liquid through the outer wall, at least during a relative movement of the pulsation roller to the outer wall.

Firstly, a much more intensive washing has become possible compared to conventional washing methods. Second, the driving style has become flexible. For example, different perforations of the washing roller and / or geometric configurations of the pulsation roller can achieve an optimal washing result, depending on the textile product. The invention allows the tape washing device to be correspondingly adaptable, which also achieves savings, for example the saving of washing additives.

According to further advantageous embodiments, the pulsation roller on individual segments or consists of such individual segments. The individual segments are attached along the Pulsationswalzenrotationsachse on a running inside the Pulsationswalze, continuous wave. The power transmission from the through shaft to the plugged segments is preferably carried out positively and / or non-positively, particularly preferably by means of feather keys.

The pulsation roller, in particular consisting of the attachable segments and the continuous shaft, is carried out according to further advantageous embodiments either on both sides or on the fly. For this purpose, the continuous shaft on the drive side is preferably connected by a plug connection with a driving stub shaft. For bilateral storage is a storage on the remote drive side, especially in a revision cover added.

The advantage of the segmented design is that it allows individual pulsation rollers to be configured for more targeted washing. A segment having a pronounced surface structure is plugged according to an advantageous embodiment of the washing method according to the invention where the greatest washing effect is needed. Round dummy segments and / or spacers are plugged there according to further advantageous embodiments, where no pulsation would be beneficial. Such positions can now be found in test series in practical application by means of such flexible washing systems.

So far, it seems to be advantageous that, according to further advantageous embodiments, such placeholder segments are arranged underneath non-perforated or covered regions of the outer wall. An economic advantage should be that with such Platzhaltersegmenten on the continuous shaft of the pulsation roller through perforated outer walls used and still sufficient Beipasseffekte could be avoided. Thanks to the inspection cover solution, the segments of advantageous embodiments can be quickly exchanged with different widths for different textile widths in order to meet the requirements of the next production variant.

If one wanted to achieve this with one-piece continuous pulsation rollers, one would have to stockpile a large number of pulsation rollers with corresponding geometries, which would also be difficult to manufacture. This will be more beneficial for plants with few changes in the types of product produced.

An advantageous embodiment of the invention has on the drive side facing away from the sink over easy to remove inspection cover. If you remove the inspection cover, you can remove due to a specially designed shaft and bearing construction, both the outer wall of the washing roller (s) and the pulsation (s) without much effort. This also gives you the opportunity to remove soiled rollers and replace them with clean rollers. A drastic reduction in set-up and cleaning times is the result.

Due to the special construction of an advantageous embodiment with inspection cover and form-fitting plug-in washing roller elements removal of the rollers is possible. So you can get to the interior of the rollers and the interior of the sink and clean them.

The invention will be explained in more detail below with reference to an embodiment shown in two figures. A third figure shows how that in the 1 and 2 illustrated embodiment or other embodiments can be equipped. At suitable points further advantageous embodiments will be described, which are not all shown. To the invention show

1 a detail of a simplified, perspective view of a belt washing device with a view from the drive remote side in a sink with suggested tape guide,

2 Another view from the same perspective as an overall view of a series of washbasins with two double basins and view of drive remote inspection covers and

3 a schematic sketch of a perspective view of a segmented pulsation roller.

The invention is not limited to the components of an embodiment described below or the method steps described below. Furthermore, the terminology used is not a limitation, but has only exemplary character. Insofar as the singular is used below in the description and the claims, in each case the plural is included insofar as the context does not explicitly exclude this. The phrase "first" and "second" used for ease of description, respectively, is a pure naming, whether or not there is another of the designated components.

The 1 and 2 schematically show an embodiment of a tape washing device according to the invention 1 for washing a particular textile tape 2 in a sink 4 , Such textile ribbons or textile strand formations are individually guided in the band device, folded, re-introduced to run parallel through the device a second time, so that when folded several times a single band several times side by side the sink 4 passes. Alternatively, a plurality of such bands or string formations are guided parallel to one another through the band device. If following from the tape 2 that is, this includes the driving style with several parallel bands, as long as this is not explicitly excluded in the context. Likewise, with the mention of the band 2 also includes another example of such string formations.

The ribbon 2 arrives in the representation coming from the left from a feeder 12 directly on a washing roller 20.2 , Alternatively, entry into a follow-on washbasin of a washbasin row (not shown) could initially be via a nip 7 a roller foulard 6 take place as shown on the right. The follow-up sink would be right in 1 subsequently accept. So it is after 2 outlined. The type of feed is not important to the invention.

From the roller-foulard 6 and / or in particular as a dancer control or with dancer control running feeder 12 off the band enters 2 now after that in the 1 and 2 shown embodiment from above into the sink 4 one of which in the 1 only one drive side 3 Side wall 5 and a floor are easily recognizable for better insight allow further components of the belt washing device.

In the in 2 recognizable drive away 9 Side wall are inspection openings 8th arranged. According to this embodiment, each sink has 4 two washing rollers 20.1 . 20.2 and two inspection openings 8th , Accordingly, according to this advantageous embodiment, a washing roller pair is used 20 each sink stored in a pair of revision cover. On the drive side, the bearing is preferably realized via a cantilevered drive shaft stub. Alternatively, according to a further advantageous embodiment, a one-sided storage technique is used for all rotating parts, for example at least part of the washing roller 20.1 . 20.2 ,

The 1 Viewing acts left and right or seen in a production direction the washing rollers 20.1 . 20.2 after and pre-ordered on the washing rolls rolling a single pulley 10 per wash roller pair 20 as a pressure roller. The pulley 10 is preferably not provided with its own drive but runs with the washing rollers 20.1 and 20.2 With. However, the invention also includes a not shown, separately driven pulley.

Every single wash roller 20.1 . 20.2 in the 1 and 2 illustrated embodiment has a single pulsation roller 24 arranged around a single fluid-permeable outer wall 22 , The outer wall 22 is preferably driven separately, while radially inside the pulsation roller 24 or several pulsation rollers rotate or rotate with deviating peripheral speed or deviating peripheral speeds.

As outer wall 22 According to an advantageous embodiment, a separately mounted, perforated roller with its own drive, for example a servo motor or a frequency-controlled motor is used. The washing roller pair 20 may be driven coupled as a pair within the scope of the invention. That is, according to the illustrated embodiment, at least the two outer walls would be 22 of the washing roller pair 20 coupled driven. According to an advantageous embodiment of the invention, successively arranged washing roller pairs 20 one of the sinks 4 driven coupled together.

Whether as a washing roller group with example 3 or 5 Wash rollers, pair of washing rollers or individual washing roller per washbasin, the washing rollers according to the invention can also individually and in groups matched to each other or be driven completely independently.

A driving according to the invention according to an advantageous embodiment of the belt washing method by means of the belt washing device provides that the running direction of the outer wall 22 the washing roller 20.1 . 20.2 the direction of the continuous belt 2 equivalent. This puts the invention at Pulsationswalze 24 and outer wall 22 however, not stuck to couplings or a preferred directional relationship. Same directions of rotation at different speeds are possible, opposite directions of rotation are possible, an oscillating movement of the pulsation roller 24 as well. The directions of the outer wall 22 and band 2 however, are always the same.

Run the tape 2 for example, in counter-rotating pulsation 24 or with low relative speed around the outer wall 22 the washing roller 20.1 . 20.2 provide blades according to the illustrated embodiment 26 the pulsation roller 24 for an overpressure of the wash water (not indicated in the drawing) in the region of a radially outer end section 28 the blades 26 , the perforated outer wall 22 at least almost touched along a transverse line. When turning the pulsation roller, an overpressure builds up in front of the rotor blades. Water gets here through the outside wall 22 pushed outward. Behind the shovels 26 creates a negative pressure. Here, water is sucked from radially outside to inside. The wash water passes forcibly radially in passage areas, for example, a drawing indicated passage area 29 , the perforated outer wall 22 in and / or from a (m) normal pressure range of the washbasin 4 , The washing water washes through the textile band 2 through and intensely removes, for example, excess color particles and / or soiling.

The 2 makes it clear that the washbasin 4 over two inspection openings 8th features to the washing roller 20.1 . 20.2 at least partially, so the outer wall 22 and / or the pulsation roller 24 , easy to remove for cleaning or replacement.

A at the beginning of the washing process and preferably also in the further course of the washing process arranged roll-pad 6 Forms according to previous results of development one or more, advantageously and shown two, crimp 7 out. For example, three corresponding juxtaposed rollers are in an area of out of band 2 or the tapes from the sink 4 arranged. To do this, imagine the 1 for example, several times strung together, as after 2 shown in a variant.

The invention allows an intensive penetration of the tape 2 with washing liquid, advantageous even a penetration of a not yet in the sink 4 concentrated additive from, for example, radially inward to radially outward, which according to an advantageous embodiment of the washing process specifically in the washing roller 20.1 . 20.2 can be introduced and / or but radially outside in the sink 4 into it.

In the 1 and in 3 Pulsation roller shown as a variant study 24 has in cross section according to 1 a star shape and after in 3 segment variants shown deviating geometric designs on. The invention is not limited to the star shape or a construction with a radially outer contour but includes other geometric configurations or contourless pulsation rollers. Alternatively or additionally, it is advantageous, but not shown, configured in the axial direction of a helical and / or helical geometry. The pulsation roller 24 Further advantageous embodiments has radially outer contours with flexible, radially outer end portions 28 on.

In the 3 schematically illustrated pulsation roller 24 ' is to be understood as a study for axially continuous pulsation rollers, wherein different meaningful geometries are sketched, but which would have to be executed continuously. 3 however, is also a sketch for a segmented pulsation roller 24 ' to understand. Individual segments 24.1 ' to 24.5 ' are on a continuous wave 23 ' pushed out and by feather key 21 ' secured against rotation. In the 3 represented segments 24.1 ' to 24.5 ' show various wing geometries. Instead of such segments or in addition, not shown Platzhaltersegmente have been arranged with a round cross-section, which reduced by-pass effects and targeted washing intensity could be increased.

On the outside wall 22 Further advantageous embodiments are, distributed over its axial length, not shown cover sleeves, in particular cover sleeves with radially outwardly parked web guide collar, pushed. Any otherwise free area between the bands is covered in this way. Bypass effects are largely avoided in this way.

The outer wall 22 further advantageous embodiments has distributed over its axial length different passage zones, in particular with perforation of the outer wall 22 Following a non-perforated area, then perforated again etc.

Thus, in particular in the design of the washbasin 4 with inspection cover for closing the inspection opening 8th , to certain bandwidths matching outer walls in production change depending on the order to be exchanged. The outer wall 22 According to advantageous embodiments, the respective zone or zones are dimensioned in at least one physical property, in particular a perforation of the perforation, such that the flow resistance for a washing liquid in the region of the circulating belt 2 or the circulating bands less than or equal to the flow resistance laterally of the area of the circulating belt 2 or the circulating bands. The physical property is in particular selected from the group: arrangement, size, number of holes and / or their shape.

The outer surface of the outer wall 22 advantageous embodiments has elevations and / or depressions. In the case of elevations, this embodiment does not adversely affect the mounting / demounting capability of the outer wall 22 because no larger gap between perforated roller and star roller must be provided in order to exchange the outer wall independently of the star roller can. As grooves running with internally correspondingly recessed edges of the star rollers so that a better management of the textile material can be achieved.

Good results have been achieved with perforated outer walls with a flat surface, with inside star rollers with straight edges produced pulsations.

The outer wall 22 and / or the pulsation roller 24 further advantageous embodiments has or at least in sections, a conically tapering to one of their length smaller cross-section tapered or a total of a frustoconical basic shape.

The washing roller 20.1 . 20.2 further advantageous embodiments is exclusively in a single of the side walls 5 , especially on the drive side 3 , the washbasin 4 stored, particularly preferably with the formation of a revision cover for the inspection opening 8th , This facilitates their change with little downtime.

The outer wall 22 and / or the pulsation roller 24 Further advantageous embodiments are supported on the drive side 3 on a driving stub shaft and on a non-powered side 9 via a sliding bearing (not shown), wherein the driving stub shaft particularly preferably one of the side walls 5 penetrates and outside the sink 4 is stored flying. A stub shaft for supporting the outer wall is preferably designed as a hollow shaft and positively connected via claws with the perforated roller. A storage and driving Stub shaft for the pulsation roller 24 is preferably a solid shaft, which runs in the hollow shaft and form-fitting with the pulsation roller 24 connected is.

The washing rollers 20.1 . 20.2 are according to advantageous washing method according to the invention completely or at least partially surrounded by the washing liquid when the shape and motion-induced pulsation is used by means of pulsation. Alternatively, however, the invention also includes an insert instead of the pulsation roller, such as a nozzle tube, so that the washing effect can be achieved without the level in the sink 4 must necessarily be so high.

The drives are coordinated so that a sensitive controlled transport of the belt is ensured as a continuous movement through the sink or the sink. For this purpose, the drives of the outer walls are preferred by means of dancer control, force measuring bearing, etc. 22 and the roller foiling 6 controlled or regulated by the tapping of the voltage applied to the fabric tension.

The schematic sketch of the 3 shows more the variety of different geometry options and less a "practical" arrangement.

Although the invention has been described in detail in the drawings, the illustration is to be considered as illustrative and nonlimiting. In particular, the invention is not limited to the illustrated embodiment. Other variants of the invention and their execution will become apparent to those skilled in the art from the foregoing disclosure, the drawings and the claims.

Terms used in the claims, such as "comprising," "comprising," "including," "containing," and the like, do not exclude other elements or steps. The use of the indefinite article does not exclude a majority. A single device can perform the functions of several units or devices mentioned in the claims.
