Field of application of the invention

The invention relates to a Tambourkratzenrauhmaschine for textile fabrics.

Characteristic of the known state of the art

To achieve a rough effect, drum-type roughing machines have scraper rollers (counter-scrape scratch rollers and / or bar scratch rollers). In order to avoid a displacement of the scraper rollers caused by the roughing fabric fabrics lint, the scraper rollers is assigned a Ausputzeinrichtung, the two each with at least one expeller blade

occupied Ausputzwalzen owns (German Altpatent 81891). The one cleaning roller is used to clean the counterstay scraper rollers while the other scrapers are used to clean the scraper rollers. However, this emptying device is only suitable for cleaning of scratching rollers with a constant ratio of counterstay scratching rollers to bar scratching rollers.

Object of the invention

The aim of the invention is to provide a Tambourkratzenrauhmaschine with a universally applicable Ausputzeinrichtung.

Explanation of the essence of the invention

The invention has for its object to make a Tambourkratzenrauhmaschine according to the preamble of the first claim so that the dispenser can be used even when changing the ratio of Gegenstrichkratzenwalzen to Strichkratzenwalzen or only one type of Kratzenwalzen.

This object is achieved in that the two cleaning rollers is associated with at least one further, between a working position and a position outside the working position pivoting cleaning roller and that one of the two cleaning rollers is driven separately.

Other essential features of the invention will become apparent from the claims following the first claim.

By the solution according to the invention, it is possible that even in the case of changing the ratio of Gegenstrichkratzenwalzen to Strichkratzenwalzen or when roughening with only one type of Kratzenwalzen a relatively good cleaning of all located in working position Kratzenwalzen is reached.

embodiment

The invention will be explained in more detail below using an exemplary embodiment. In the accompanying drawing shows

Fig. 1: a schematic cross-sectional view of a Tambourkratzenrauhmaschine with a different number itself

2 shows a schematic cross-sectional representation of a drum-type roughing machine with an equal number of counterstay scratch rollers and bar scratch rollers in the working position.

As can be seen from the figures, the tambourrauhmaschine has a stored in two side uprights, not shown, driven spool. To this drum belong essentially two serving for storage of a plurality of recording devices 1 Tambourscheiben 2, of which only one has been shown in Figure 1. Each receiving device 1 is preferably equipped with two countercurrent scraper rollers 3 - hereinafter referred to as G in the figures and a scraper roller 4 below and also referred to in the figures as S- equipped with the scraper rollers 3 and / or on the pitch circle 2.1 4 are in working position. For reasons of clarity, the marking with the corresponding reference numerals was carried out only at a receiving device 1 and the stored therein Gegenstrichkratzenwalzen 3 and the Strichkratzenwalze 4. The stored in the Tambourscheiben 2 recording devices 1 are rotatably mounted and lockable by a device, not shown in their position. Upon rotation and subsequent locking of receiving devices 1, the following variants of scratching rollers 3 and / or 4 in working position are possible:

relationship repetitive order G to S at two consecutive Recording devices 1 (seen clockwise) FIG. 1 3: 1 G-G-G-S -... FIG. 2 1: 1 G-S-G-S -... after turning all the recording on directions 1 to 120 ° opposite Figure 2 at twenty four in Working position licker-in rollers 24: 0 G-G-G-G -... (G: 0)

The Tambourkratzenrauhmaschine also includes a Eingangszugwalze 5 and a Ausgangszugwalze 6, with which the transporting over the spool textile fabric 7 is transported while being held under a certain tension. Furthermore, the tambour is associated with a Ausputzeinrichtung. This dispenser has three cleaning rollers 8,9 and 10, wherein the cleaning roller 8 with two diametrically opposite Ausputzblättern 8.1 and 8.2, the cleaning roller 9 are also equipped with two diametrically opposite Ausputzblättern 9.1 and 9.2 and the cleaning roller 10 with a cleaning blade 10.1.

The drive of the cleaning roller 8 is effected by a motor 11, while the cleaning roller 9 with a serving for the drum Drive 12 is in communication. For driving the cleaning roller 10 is an outgoing from the cleaning roller 9 drive,

Preferably, a toothed belt 13. The speed of the cleaning rollers 8,9,10 is, corresponding to that shown in Figure 1

Arrangement of the counterstay scratching rollers 3 and bar scratching rollers 4 located in working position, chosen such that

during the passing of the scratching rollers 3,4 at the emptying device in each case a cleaning sheet 8.1,8.2 the

Cleaning roller 8 each a bar scratching roller 4 and each a cleaning sheet 9.1,9.2 the cleaning roller 9 and the cleaning sheet

10.1 of the cleaning roller 10 each cleans a counter-scrape roller 3, that is largely freed from lint.

According to Figure 1 are thus the three cleaning rollers 8,9,10 in working position. By coupling the drive of the spool with the cleaning roller 9 and thus also with the cleaning roller 10th

as well as the control side with the motor 11 is a cleaning of the respective Kratzenwalzen 3.4, even when changing the

Drum speed, guaranteed. Furthermore, at least one spool disk 2 is a scanning element 14 and the cleaning roller 8 is a further scanning element 15

assigned, in addition to the determination of the initial position of the spool and the cleaning roller 8 also have the task, if required via a control device 18 to drive the motor 11 so that appropriate corrections of the cleaning roller 8und thus the position of the cleaning leaves 8.1,8.2 to the respective scraper rollers automatically can be triggered. When

Sampling elements 14,15 are preferably used sensors. The cleaning roller 10 mounted in a lever linkage 16 is separated by a working cylinder 17 between one shown in FIG Working position and shown in Figure 2, lying outside the working position position. The fulcrum of Lever linkage 16 is preferably mounted in alignment with the axis of the cleaning roller 9. The solution according to the invention works as follows: The textile fabric 7 is guided over the tension rollers 5, β and the spool - the direction of the textlien Sheet 7 by the Tambourkratzenrauhmaschine is shown attached to the sheet 7 arrows -

and roughened by the scratching rollers 3 and / or 4 in working position. According to FIG. 1, twenty-nine scratching rollers 3, 4 which are in the working position, have a repetitive sequence of three

Counter scrape rollers 3 to a bar scratch roller 4 vor the ratio counter scraper rollers 3 to Bar scratching rollers 4 is 3: 1. When moving past the working in position scratch rollers 3,4 at the Mop cleaning the cleaning cloth 10.1 respectively the middle of the three Gegenstrichkratzenwalzen 3 a

Repeat order, while the one cleaning sheet 9.1 of the cleaning roller 9, the one of the two outer and the

Exposure sheet 9.2 of the cleaning roller 9, the other of the two outer in a repetitive order

existing counter scraper rollers 3 cleans. Through the cleaning leaves 8.1 and 8.2 of the cleaning roller 8 are the

Bar scratching rollers 4 cleaned. In this case, the one cleaning sheet 8.1 hits the line scraper roller 4 of the one and the other Exposure sheet 8.2 on the bar scratching roller 4 of the following order. When changing the ratio of counterstay scratching rollers 4 to bar scratching rollers to 1: 1, as shown in Figure 2,

the mounted in the lever linkage 16 cleaning roller 10 is pivoted by the hinged to the lever 16 working cylinder 17 from the working position, as it is at a ratio of 3: 1, in a position out of working position, so that only the cleaning rollers 8.9 in Working position. For the purpose of cleaning the

Scratch rollers hits the Ausnutzblatt 8.1 on the one and the Ausputzblatt 8.2 on the following Strichkratzenwalze 4, while

the cleaning sheet 9.1 which cleans the one of the line scraper roller 4 countercurrent roller 3 and the brush sheet 9.2 the following counter scraper roller 3. Due to the smaller distance of the bar scratching rollers 4 to each other, as is the ratio of counterstay scratching rollers 3 to bar scratching rollers 4 of 1: 1 compared to a ratio of 3: 1, there is twice the speed of the removal roller 8 compared to a ratio of 3: 1.

Another variant is that only countercurrent scratch rollers 3 are in working position. This is located

the cleaning roller 10 also outside its working position, while the Ausputzwalze 8 in the opposite direction of rotation and at a speed which is also present at the ratio of Gegenstrichkratzenwalzen 3 to Starzkratzenwalzen 4 of 1: 1, is driven.

From the following overview, the functions of the cleaning rollers 8,9,10 in the corresponding ratios of Countercurrent scratch rollers 4 to bar scratch rollers 3 can be seen. Where:

An exact positioning of the respective cleaning sheets 8.1,8.2 to the respective scraper rollers is carried out in dependence on measurement results of at least one drum associated sampling element 14 and the cleaning roller 8 associated scanning 15. This positioning is both when setting up the drum and the cleaning roller 8, for example in the Changing the ratio of countercurrent scraper rollers 3 to Streak scrape rollers 4, as well as in a corresponding position correction of the cleaning roller 8 and thus the attached cleaning leaves 8.1,8.2 possible. However, it is also possible to assign the scanning element 14 of the cleaning roller 9 and / or the cleaning roller 10. In this case, the measured quantities of the scanning elements 14, 15 represent the input variables for the regulating device 18. The output variable of the regulating device 18 acts on the motor 11 directly or indirectly.

The arrows shown in FIGS. 1 and 2 show the direction of rotation of the spool disks 2 and thus of the spool, of the sprocket rollers 3, 4 and of the cleaning rollers 8, 9, 10. However, it is also possible to drive the tambour in the opposite direction for the purpose of so-called Gegenrauhens. The existing direction of rotation of the drum disks 2, the scratch rollers 3,4 and the cleaning rollers 8,9,10 is shown in Figures 1 and 2 by arrows, each with a broken line.
