Description

The invention relates to a device for receiving a web, a damping device for damping a web and a method for inserting a web into such a device.

In textile machines, for example in washing machines, are common Damper installed. A continuously guided web is supposed to be exposed to a saturated steam atmosphere in a steam compartment become. For this purpose, it is already known to move the web several times to turn rotatably mounted rollers. The dwell time of the web in a steaming compartment with predetermined external dimensions can be increased. Such vapors have a disadvantage in that the insertion of the web is proportionate is time consuming. The web has to be wrapped around each individual roller become.

In textile machine construction there are also so-called goods stores known. To temporarily record a certain length of a web or a buffer for different goods supply and It is known to create discharge speeds on the material web several times to loop rotatably mounted rollers. A first group of rollers is fixed. A second group of rollers can be moved transversely to the direction of the web. In a The slidably arranged rollers are in the insertion position below the fixed rollers arranged so that a web just between the group of fixed and the Group of slidably arranged rollers are carried out can. Then the slidably arranged rollers moved transversely to the direction of the web so that a Wrapping the web around the rollers results. To this In this way, the length of the goods that can be accommodated in a compartment is increased. By adjusting the distance between the fixed ones and the slidably arranged rollers can be inserted Achieve balance when the feed speed and the take-off speed the goods are not identical. The web can be temporarily stored in such a device become.

These devices also have various disadvantages. In particular, the amount of goods stored in the way can be restricted. Per pair of fixed and flexible arranged rolls can accommodate a length of goods, which is about twice the distance between these roles. The distance between the roles can not be enlarge as desired, otherwise the ones acting on the material web Forces would be too great.

It is an object of the present invention to address the disadvantages to avoid the known, in particular a device to create a web in which in a compartment the greatest possible length of material with a predetermined size can be included. The web should be simple and Can be inserted into the device without great manual effort his.

Another object of the invention is a damping device to dampen a web at which the web can be inserted easily. It should be the longest possible web length in a steaming compartment let predetermined dimensions be treated or should the length of stay the web in a damper with predetermined dimensions increase.

Another object of the invention is to provide a To create a damping device as a component of a textile machine where the web, if no damping is desired is to be passed directly through the damping device can, i.e. without wrapping.

According to the invention, these tasks are carried out with a device for Inclusion of a web, a steaming device and a method for introducing a web into such a device solved with the features of the independent claims.

The device for receiving a web has a plurality of rotatably mounted rollers around which the web can be guided is. Here and below is generally from a web spoken. All types of flat are under web Forms, in particular textile webs such as woven or knitted fabrics but also other continuously funded or eligible Goods, for example a thread group understood.

The first rollers are fixed in the device and the second Rollers are slidably arranged in the device. Here and In the following, the first and second rollers are fixed or understood slidably arranged rollers. The second reel are between an insertion position and an operating position so displaceably arranged that in the insertion position Material web essentially straight between the first and second Rolling is feasible and that in the operating position the web alternately wraps around the first and second rollers. In this context, operating position means Position at a distance from the insertion position. The operating position can also change in operation (e.g. by speed differences balance between web feed and removal). The second rollers can be in one direction across the web move in the insertion position. Cross in this means Connection not parallel to the web. Typically the direction of displacement approximately perpendicular to the web in the insertion position.

The first and second rollers are each in at least two groups arranged. The at least two groups of the first rollers and the at least two groups of the second rollers are each at a distance arranged to each other, each group preferably about is arranged in one plane. These levels run approximately parallel to each other and parallel to the web in the insertion position. The planes are defined by the axes of the rollers. The first and second rollers are in the direction of displacement of the second rollers aligned with each other.

This device has several advantages. If the device is in the insertion position, the web can simple and essentially straight between a group of first and second rollers are performed. Subsequently can the web between another group of first and second rollers are carried out.

The second rollers can then be in the operating position be moved. This results in a loop around the web around the first and the second rollers, whereby the in the device recordable length of goods is increased. Because the first and second rollers each arranged in at least two groups and aligned with each other in the direction of displacement of the second rollers there is a nesting of the individual Looping the web, but without the insertion process in the is significantly more difficult.

The goods are passed through the device bound. It is not necessary, a large distance between the fixed and the movably arranged rollers to provide sufficient Record web length in the device. Adequate The length of the goods that can be picked up is already determined by the nesting achieved. If a textile machine with such a device should be operated without the dwell time of the Goods are increased in the device, they can with the device be operated in the insertion position. The web will then simply passed directly through the device without wrapping.

According to a preferred embodiment, the one according to the invention Device with a sump to dampen the web Mistake. The swamp is known as a basin trained to absorb water, which by heat can be evaporated.

According to a further preferred embodiment, the second rollers can be moved together. Wrapping the web this simplifies the plurality of rollers. The operating position can be adjusted by moving all the second rollers together can be achieved. The two rollers are preferred supported on both sides on a slide in the device is movable. The carriage can roll in the area of the first have recesses running in the direction of displacement. This allows the carriage within a housing for the device be arranged without the fixed, first Rollers hinder the moving process.

The distance between groups with rollers of the first type or Rolls of the second type are advantageously approximately the same. In one preferred embodiment are the second rollers around a Distance slidable, which is at least about twice the distance between neighboring groups of a certain type of roller, i.e. of first rolls or of second rolls.

An odd number of groups or levels is advantageous with first rollers and groups or levels with second rollers intended. Typically five groups can be provided his. An odd number of groups will result in the web fed on one side of the device and on can be guided away from the other side of the device. For example with five groups of fixed and movable arranged rollers, the web is in the insertion position twice through the device and back again and then passed through the device again.

The operating position can also be adjustable. This means that depending on the length of the material web in the device should be recorded or depending on the desired length of stay, the second rollers are moved into a corresponding position and that the device can be operated in this way.

According to a further aspect of the invention, a damping device proposed for damping a web. The damping device has a plurality of rotatable in a known manner stored rollers around which the web can be guided. The Damping device is also with a sump to dampen the Provide web. Typically, a device can be use the type described above. According to the invention the damping device has a group of first, fixedly arranged Rollers and a group of second, across the web so displaceable between an insertion position and an operating position arranged rollers on that in the insertion position the web one straight between the first and second Rolling is feasible and that in the operating position the web alternately wrapping the first and second rollers. According to In this aspect, a web store with approximately one each Laying fixed and movable rollers in one Damping device used. Training is a matter of course of the goods store with several, spaced apart Groups of first and second rolls from the above Reasons particularly advantageous.

To introduce the web into the aforementioned device first the web between a group of fixed Rollers and a group of slidably arranged rollers carried out. This process is for at least one more each Level of first and second rollers repeated. Subsequently the second rollers are moved so that the web alternately wraps around the first and second rollers.

The invention is explained in more detail below in exemplary embodiments and with reference to the drawings. Show it:

Figure 1 shows a textile machine 10 with different known components is provided. The textile machine 10 has a device 1 for receiving a specific one Length of a web is used.

The device 1 is shown in FIG. 2 in a side view.

The device 1 has first rotatably mounted rollers 2 provided, which are arranged in a fixed position. The device 1 also has rotatably mounted second rollers 3 on, which are displaceable in a direction R. The first reels 2 are arranged in five groups P. One group P each first roller 2 lies in one plane. The second rollers 3 are also arranged in five groups P '. Each group P 'lies in one level. The distance between adjacent groups P from first Rolls 2 (or between the axes) is a. The distance between adjacent groups P 'of second rollers 3 each b. The distances a, b are in the exemplary embodiment shown the same size, but this is not mandatory. In the embodiment according to FIG. 2, five groups each of the first Rollers 2 and five groups of second rollers 3 are shown. It is but a different number of groups is also conceivable.

In Figure 2, the device 1 is in an insertion position E. A web W can be introduced around a deflection roller 8 and between the lowest group P 'of second rollers 3 and the bottom group P of first rollers 2 through the device 1 can be carried out. Then the web is between the second and first rollers 2, 3 from further groups P, P ' carried out, the goods web two times there and back is guided through the device 1. The introduction of the web W is easy because the web passes through the device only three times has to be withdrawn once and twice before being in Area of a second deflecting roller 8 'led out of the device 1 becomes. Wrapping is not necessary.

The slidably mounted second rollers 3 are on one Carriage 5 arranged. The carriage 5 is schematic in Figure 3 shown. The carriage 5 has brackets 9 which are designed in the manner of tines. Each bracket 9 carries a series of second rollers 3. By moving the carriage 5, the rollers 3 based on the device 1 together be moved. There are recesses between the brackets 9 6 provided. Not related to the device 1 Slidably arranged first rollers 2 are in the area of Recesses 6 arranged. The carriage 5 can therefore be moved without having to move through the first rollers 2 is hindered.

By the length of the web W increase, the second rollers 3 in the direction of displacement R postponed. The second rollers 3 reach an operating position B (see Figure 4). In operating position B they are second rollers 3 based on the insertion position E (see figure 2) shifted by a displacement distance d.

Per pair of rollers from a first roller 2 and a second The roller 3 can be the length of the web that can be accommodated in the device 1 increase by almost twice the displacement distance d. Since several groups of first rollers 2 and second rollers 3 in Distance is provided, the recordable Web length per unit length of the device 1 by a multiple increase without increasing the displacement distance d got to. Because in the embodiment according to Figures 2 and 4 each five groups of first rollers 2 and five groups of second ones Rollers 3 are provided, the recordable length of the web in addition, almost five times as much. The web is in individual loops wrapped around the rollers 2, 3. Due to the Arrangement of rollers in several superimposed levels the individual loops are nested one inside the other. The web W is first zigzag (as shown in Figure 4) from right to left through the device and then runs twice in a corresponding number of Zigzag loops from left to right and from right to left before it is guided around the deflection roller 8 ′ out of the device 1 becomes. In the exemplary embodiment shown, the length L the device, for example, be 2.5 meters. The distance 1 between corresponding first rollers 2 and second rollers 3 slightly less than the displacement distance d. In the embodiment shown for example, the distance 1 is 1.35 meters, so that each pair consists of a first roller 2 and one second roller 3 gives a loop length of 2.7 meters. in the Embodiment shown can be in a device a length L of 2.5 meters 110 meters of goods can be stored.

A sump is optional in the device according to FIGS. 2 and 4 4 arranged below the web W. In the swamp 4 one can Liquid F, typically water, and thus heated that it evaporates. The device 1 can be in this Operate the case as a damper, the dwell time of the web W in the damper, which is only 2.5 meters long, at a web speed can be increased from 70 m / min to 90 sec. The web W runs between thanks to the relatively short length two consecutive loops of 1.35 meters essentially bound by the device 1 so that the on the Material web W forces below tolerable Limits remain. If necessary, the rollers can at least partially be driven.

The device 1 is arranged in a housing 7.

In Figure 5, the device 1 is in the direction of movement of the web W seen shown. The first fixed rollers 2 are rotatably mounted on two side walls 11 of the housing 7. The displaceable rollers 3 are arranged on a carriage 5, which is arranged within that of the housing 7. The Carriage 5 can be moved in the direction R on rails. The Carriage 5 can be pneumatic or hydraulic, for example or operated electrically.

The group P, P 'run from first rollers 2 and second rollers 3 horizontally in the exemplary embodiment according to FIGS. 2 and 4. The axes of the rollers 2, 3 run exactly in these planes. deviations from the horizontal or arrangements of rollers one Groups slightly outside a level are within the scope of the invention also conceivable. The direction of displacement R runs in Embodiment according to Figure 2/4 vertical. Are here too Deviations conceivable without leaving the scope of the invention would.

In Figure 6 is an alternative embodiment of a damping device 1 shown. A sump 4 is arranged in a housing 7. A liquid F is provided in a basin can be evaporated by heating. This forms there is a saturated steam atmosphere inside the housing. A Material web W is fed into the housing 7 via a first deflection roller 8 and out of the housing 7 via a second deflection roller 8 '. Similar to the previous embodiments are also here rotatably mounted rollers 2, 3 are provided. First rollers 2 are fixed. Second rollers 3 are in a direction of displacement R slidably arranged. Embodiment according to Figure 6 is only a group P of first rolls 2, which in one Level lie and a group P 'of second rollers 3, which in one Level are provided. The continuous line shown W can between the first rollers 2 in the plane P and the second rollers 3 are carried out in the plane P ', if the second rollers 3 are in an insertion position E. So that the residence time of the web W in the device 1 increases can be, the second rollers 3 in the direction of displacement moved to an operating position B. In the operating position B is the web W '(shown in dashed lines) in loops between the first rollers 2 and the second rollers 3 and brought here.
