The ribbon (2) changes through at least two squeezing nips (Q1, Q2) in a revolution.

Description

Device for washing narrow, textile strips in a washbasin

The invention relates to a device for washing narrow, textile tapes in a washbasin, wherein the tape is first supplied by means of a dancer to the sink and after passing through the sink a nip, formed by two rolls of a motor-driven roller foulard is fed further the tape is helically guided through the sink and the tape passes through the sink several times with multiple enforcement of the same roll foulard.

Such a device is known from DE 19523621 C2. In this device, the tape is squeezed once per passage. A passage is a passage of the tape through the apparatus, after which theoretically the tape can leave the apparatus. The helical guidance of the tape (through the sink) repeats a passage more often in succession before the tape finally leaves the apparatus.

The invention has for its object to make a generic device for washing narrow, textile bands more efficient.

This object is achieved first and foremost in a device having the features of claim 1, wherein it is arranged that the Wai zen scarf is formed to form at least two nips of three or more corresponding to each other lying rollers and at least one roller is used to form two nips, wherein the band changes in one revolution by at least two nips. Although this requires a certain device overhead, but this means at the same time a further improvement in the fastness or can be selected depending on the requirement, ie on the type of strip, strip material, color depth, etc., a smaller sink unit.

The strip is held at the desired tension between two nip passes due to pulleys. In this case, each gap penetration exercises, because at least one of the rollers is driven, an independent transport.

The roller foulard has several nips and thus at least three rollers and the band passes through the multiple nips several times without leaving the sink. In a three-roll roller foulard, there are two nips between the rollers. Thus, the centrally located roller forms one with a laterally arranged roller

Nip. With three rollers can sometimes be achieved up to ten times squeezing the tape.

Furthermore, features are described which preferably have in combination with the features of claim 1 meaning, but in principle may have meaning with only some features of claim 1 or alone.

Thus, in particular, it is also provided that the band penetrates the multiple pinch gaps several times without leaving the sink and that a plurality of deflection rollers are provided. The deflection rollers are preferably arranged below the water level in the wash basin. The Walkeinwirkung thus taking place in the water on the band in the course of the deflection advantageously supports the washing process. The rollers can with respect to their axes of rotation vertically one above the other or horizontally next to each other or one acute angles with a horizontal or a vertical einschließ be arranged. Furthermore, the rollers may be arranged such that perpendicular to the axes of rotation of the rollers extending connecting lines form when projecting in a common plane intersecting straight lines. In the last-mentioned arrangement, the connecting lines of the rollers have a triangular arrangement relative to one another, that is to say that in each case the axis of rotation of a roller is assigned to a tip of a triangle.

Furthermore, more than three, in particular four or five, rolls can be provided. The rollers are preferably arranged horizontally next to one another. By four or five rollers is achieved that the band more often than previously mentioned assigned to the same sink in different nips can be squeezed off. In the case of four rolls, three squeezing gaps result accordingly in juxtaposition and correspondingly four squeezing gaps in the case of five wafers. The individual squeezing gaps can in turn, as in principle in the above-described embodiments, be repeatedly passed through by the belt.

The offset within the helix is achieved by a laying unit. Each turn of the helix is assigned in each case a laying unit. Through the laying unit, it is possible to run the tape in a stretched way helically multiple times through the sink. It is understood that there is no classical helix, but only in the strand an offset in which the laying unit actually works. The laying unit itself is preferably an elongated roller disposed on the apparatus such that the tape is forced by the laying unit to traverse the helical path. Furthermore, the laying unit is preferably arranged so that, before the band passes through one and the same nip again, this is offset from the laying unit. Thus, the given nip with respect to a juxtaposition of the permeating band sections are used to advantage. Overlays are prevented.

Furthermore, it is provided that a plurality of devices, in one of the embodiments as described here, are arranged one behind the other, with a respective wash basin being associated with each device. Preferably, the tape is fed after the last washbasin a drying device.

The invention will be explained in more detail below with reference to the accompanying drawing, which shows only exemplary embodiments. It shows:

Fig. 1 is a schematic representation of a first embodiment, wherein the rollers are arranged vertically one above the other;

Fig. 2 is a schematic perspective view of the first embodiment from the front view;

3 is a schematic perspective view of the first embodiment from the rear view;

Fig. 4 is a front view of a second embodiment, wherein the rollers are arranged diagonally;

Fig. 5 shows a third embodiment, wherein the rollers are arranged in triangular shape to each other;

Fig. 6 shows a fourth embodiment, wherein the rollers are arranged horizontally next to each other and Fig. 7 shows a fifth embodiment, wherein five rollers are arranged horizontally next to each other.

With reference to FIGS. 1 to 3, a first exemplary embodiment of a device 1 for washing tapes 2 is shown. The device 1 consists essentially of a frame 3, a sink 4, a dancer unit 5 and the roller foulard. 6

The frame 3 receives the aforementioned elements. The roll padder 6 consists of three rolls 7, 7, 7 "arranged vertically one above the other. The horizontal arrangement of the rolls 7, 7, 7" produces a space-saving design of a device 1 with regard to the widthwise extension. The three rollers 7, 7, 7 "are preferably pressed against one another pneumatically Furthermore, it is also possible to press the rollers 7, 7, 7" against one another hydraulically, mechanically or by means of a spring. At least one of the three rollers 7, 7, 7 "is driven by a motor, not shown, In this embodiment, the roller 7" is preferably driven by the motor. In this case, the motor may be attached to the frame 3 in close proximity to the roller foulard 6. The not driven by the motor rollers 7,7 'are driven by the pressing of the rollers 7, 7', 7 "of the motor-driven roller 7" with. The arrows in the drawing indicate the respective direction of rotation of the individual roller 7, 7, 7 "The rollers 7 and 7 ¹ form between them a first nip Qi and the rollers 7 ¹ and 7" form a second nip Q ₂ between them , The squish gaps Qi, Q ₂ are arranged in vertical overlap with the wash basin 4, but the rollers 7, 7 ', 7 "can protrude beyond the wash basin 4 with their circumference.

Below the roller 7 "there is arranged a collecting container 8. The collecting container 8 has a discharge 9 on its underside Direction of the washbasin 4. Thus, from the collecting container 8 collected water, which has been squeezed from the roller foulard 6, via the drain 9 the sink 4 again fed or discharged. Also, the sink 4 is arranged below the roller foulard 6. The sink 4 has on its underside a drain, by means of which the water can be drained from the sink 4. The dancer device 5 is arranged above the roller foulard 6.

The belt 2 is guided through the roller foulard 6 and the wash basin 4 via a plurality of deflection rollers, which are explained further below. By means of the motor-driven roller padder 6, the band 2 is pulled into the device 1 by an upstream device, for example a dyeing, damping device or the like. In this case, the tape 2 runs counterclockwise about a first guide roller 10 in the direction of a next guide roller 11 of the dancer 5. The belt 2 rotates the guide roller 11 in a clockwise direction. Now, the band 2 is pulled by the motor-driven roller padder 6 through the first nip Qi between the rollers 7, 7 ¹ . Starting from the nip Qi around a deflection roller 12, the belt 2 runs into the washbasin 4 and circulates in the clockwise direction a deflection roller 13 arranged in the wash basin 4 in the direction of the roller foulard 6. The belt 2 is now moved through the second nip Q ₂ between the rollers T and 7 "is guided again in the direction of the washbasin 4 by a further deflection roller 14 arranged in the washbasin 4. Thereafter, the belt 2 passes over a laying unit 15 so that the belt 2 is displaced and does not pass through the first nip Qi in superposition After the laying unit 15, the band 2 again runs into the nip Qi around a deflection roller 16. Now, the band 2 can again dip around the unclamping roller 12 into the wash basin 4. The course of the band 2 described above corresponds to a passage The band 2 again pass through such a passage or are guided around a deflection roller 17 and the Leave device 1. For example, in FIGS. 2 and 3, some passes of the belt 2 are shown until the belt 2 finally leaves the device 1. Also, in the figures, the arrows indicate the course of the tape 2. As can be clearly seen in FIG. 3, each turn of the helix is initiated by a single laying unit 15. The tape 2 comes squeezed out of the device 1 out. In one pass of a passage, the tape 2 is squeezed twice. In two passes, the tape 2 is therefore already squeezed four times. Depending on the width of the band 2 different numbers of passages can be generated in a device 1. The more passages the band 2 passes through, the more often the band 2 is squeezed off. For clarification, in FIGS. 2 and 3, a complete passage, that is to say a passage, is marked with a hatching.

A second exemplary embodiment of a device 1 will be described with reference to FIG. Like elements are further identified with the previously used reference numerals.

In this embodiment, the three rollers 7, 7 "of the roller foulard 6 are arranged diagonally at an angle of 45 ° to a horizontal, whereby the vertex points in the direction in which the belt 2 leaves the device 1 In each case, for example, a collecting container can be provided underneath the rollers 7 ", 7"", which then supplies the squeezed-off water back to the washbasin 4 or is directly discharged therefrom, and the squeezing gaps Qi, Q ₂ are also vertically overlapped Washbasin 4 arranged.

As already described above, the belt 2 runs around the deflecting roller 10 and the deflecting roller 11 of the dancer device 5. Subsequently, the band 2 rotates around the deflection roller 12 and is deflected in the direction of the wash basin 4. Before the tape 2 is guided into the sink 4, the tape is the second guided over the laying unit 15. After the laying unit 15, the band 2 is guided around the deflection roller 13 through the wash basin 4 and then deflected around the roller 7 again in the direction of the wash basin 4. Before that, however, the band 2 passes through the first nip Qi between the rollers 7 and 7 \ After the first squeezing of the belt 2, this is again performed by the guide roller 14 through the wash basin 4. After the band 2 has passed through the washbasin 4, it is passed through the second nip Q ₂ between the rollers 7 ¹ and 7 "in a clockwise direction Starting from the second nip Q ₂ , the band can leave the apparatus 1 via the deflection roller 12 or the band 2 is again supplied to the laying unit 15 and thus subsequently to the sink 4 by means of the deflection roller 12. The passage described above is repeated Before the band 2 leaves the apparatus 1, it is squeezed off through the nip Q ₂ .

The laying unit 15 is arranged in this embodiment at a different location than in the first embodiment. The position is always chosen so that there is no overlap of the band 2 within the device 1 and the band 2 can pass through several passages in a row.

FIG. 5 shows a third exemplary embodiment of a device 1. Again, the previously used reference numerals will continue to be used. Here, the rollers 7, 7 \ 7 "of the roller foulard are triangular-shaped, whereby the roller T points away from the wash basin 4.

Again, the band 2 is initially around the pulleys 10 and 11 as described above. After the deflection roller 11, the belt 2 rotates in the counterclockwise direction the deflection roller 16 and then overruns the laying unit 15 in such a way that the belt 2 is guided in the direction of the wash basin 4. Now, the band 2 around the deflection roller 14 by the washing 4 guided and then deflected in the direction of the roller 7. The belt 2 rotates the roller 7 in a clockwise direction and is thus directed by the first nip Qi, which arises between the rollers 7 and 7 ¹ , again in the direction of the wash basin 4. By means of the deflection roller 13, the belt 2 is guided through the washbasin 4 and deflected in the direction of the roller 7 "The belt 2 is guided after the deflection roller 13 through the nip Q ₂ which is formed between the two rollers T and 7". After the nip Q ₂ , the belt ₂ can leave the device 1 via a deflection roller 17 or the belt is guided counterclockwise about the roller 7 ¹ , starting from the nip Q ₂ , so that the belt 2 can again circulate the deflection roller 16 in the clockwise direction , Starting from the deflection roller 16 then the band 2 again passes through the passage described above. Also in this embodiment, the belt 2 leaves the device 1 squeezed.

A fourth exemplary embodiment is shown in Figure 6, with the rollers 7, 7 "of the roller foulard 6 being arranged horizontally next to one another Here, the previously used reference numerals are also used, As already mentioned above, the squish gaps are also in this embodiment Qi, Q _{2 arranged} in vertical overlap to the washbasin 4. In this embodiment, for example, the rollers 7, 7 ', 7 "are each assigned a collecting container. Thus, even here the squeezed water could be returned to the sink 4 or discharged directly.

In this embodiment, the band 2 initially circulates the deflection rollers 10, 11 and 16 as described above. After the circulation of the deflection roller 16, the band 2 overflows the laying unit 15 and is guided around the deflection roller 14 through the wash basin 4. Starting from the deflection roller 14, the belt 2 is fed around the roller 7 in a clockwise direction to the first nip Qi. Starting from the first nip Qi the tape 2 is again the Sink 4 supplied. The band 2 rotates the deflection roller 13 in the counterclockwise direction and is then directed in the direction of the roller foulard 6. After the deflection roller 13, the belt 2 is guided through the nip Q _{2 of} the rollers T and 7 "Starting from the nip Q ₂ , the belt 2 can rotate the deflection roller 17 clockwise and leave the device 1. However, it is also possible that The belt 2 rotates the roller 7 ¹ in the counterclockwise direction and is again deflected counterclockwise about the deflection roller 16. The belt 2 can pass through the previously described passage again starting from the deflection roller 16. Again, the belt 2 leaves the device 1 when squeezed out.

In Figure 7, a fifth embodiment is shown, wherein the roller foulard 6 of five horizontally juxtaposed rollers 7 to 7 "" consists. Thus created between the roller 7, T of the nip Qi, between 7 ¹ and 7 "of the nip Q _2, between the roll 7 'and 7'" of the nip Q3 and between the roller 7 '' and 7 '' of the nip Q ₄ , Again, previously used reference numerals are still used and denote like parts. Here, for example, each roller 7-7 "" can be associated with a collecting container in order to supply the squeezed washing liquid back to the washing basin 4 or also to remove it directly.

As described above, the belt 2 rotates the deflection roller 10 and the deflection roller 11 of the dancer device 5. After the deflection roller 11, the belt 2 rotates the deflection roller 17 in a clockwise direction and is supplied to the wash basin 4. The band 2 is guided around a deflection roller 18 through the wash basin 4 in the direction of the roller 7. Counterclockwise, the belt 2 orbits the roller 7 and is fed to the first nip Qi. Starting from the nip Qi the tape is again supplied to the sink 4 and rotates a guide roller 13 in the counterclockwise direction. The deflecting roller 13 deflects the belt 2 in the direction of the second nip Q ₂ between see the rollers 7 ¹ and 7 ". From there, the tape 2 runs around the roll 7" counterclockwise and then passes through the nip Q3. The belt 2 is guided starting from the nip Q3 in the direction of the wash basin 4 around the deflection roller 14. From the deflection roller 14, the belt 2 is fed via the laying unit 15 to the nip Q ₄ , which is formed between the rollers 7 '"and 7". "The belt 2 runs from the nip Q ₄ around the deflection roller 16, which above the rollers - Foulards 6 is arranged clockwise Now, the belt 2 leave the device 1 or it is again supplied to the guide roller 17 to the sink 4. Starting from the guide roller 17, the belt 2 can again pass through the passage described above in the embodiments previously, the band 2 leaves the device 1 squeezed.

The tape guides shown here of the individual embodiments show only one possible variant. The band 2 can also be passed through the device 1 in a different way. Due to the nature of the guidance of the belt 2 by the device 1, the number of pinchings can be varied. Also in these embodiments, preferably the rollers 7 to 7 "" are pneumatically pressed against each other. This is not shown in detail in all figures, since the figures only schematically represent the structure of the device. As described in the first embodiment, also in the other embodiments, at least one roller is driven by a motor.
