Air filter device with sieve cylinder for devices for the treatment of textile goods for the separation of fibers or fiber flocks "

The utility model relates to an air filter device with a screen cylinder, the rest of which is closed Inner sealing to an air suction device having a motor and a suction fan is connected and on the circumference of which at least one brush is immovable in the surface line direction is arranged for devices for the treatment of textile material for the separation of fibers or fiber flakes.

In treatment devices that require air, in particular warm air, to operate, there are in the air emerging from the treatment device, fibers or fiber flocks, which are

act to remove the textile goods from this. If the air is simply sucked through the treatment device, the foreign matter would get into the air suction device and, if this is preceded by a sieve, this would soon become clogged.

In order to avoid this disadvantage, an air filter device with a screen cylinder is provided. Known air filter devices have a rotatably mounted screen cylinder which rotates continuously about its axis during operation of the air filter device. In addition, disposed on its circumference at least one brush in the envelope line direction immovably which the collected fibers or fiber flocks strips during the rotation of the screen cylinder ,, However, since the air suction device is always on _T and the parsers are or fiber flocks pulls against the screen cylinder, stripping is difficult and at least some of the stripped fibers or fiber flocks are repeatedly sucked onto the screen cylinder. In another known air filter device, which serves to separate the cotton fibers transported in an air stream, customers are therefore provided that remove the fleece forming on the screen cylinder as a continuous band unsuitable for their size.

The utility model is based on the task of creating a To create air filter device for devices for the treatment of textile goods, "with the simple means the separated fibers or fiber flocks are removed from the screen cylinder so that they can be used, for example Collection box can be fed.

To achieve this' purpose is in an air filter device According to the utility model, a motor or an overrunning clutch to drive the screen cylinder step by step, whose driven part drives the screen cylinder, provided and the screen cylinder so with the air suction device coupled that the air suction device during the incremental rotary movement of the screen cylinder is switched off «,

Since no air is sucked through the screen cylinder during the stripping process, the screened out fibers can or fiber flocks can be easily and completely stripped off by means of the brush or brushes provided. Also be the stripped fibers or fiber flakes are no longer against sucked up the screen cylinder so that they can be fed to a collecting box without difficulty "

The driving part of the overrunning clutch is expediently stationary or the motor with the switching mechanism of the loading

action device in connection. Controlling the Step-by-step rotation of the cylinder, for example by 60 ° in each case, can thereby be passed to the control in a simple manner the treatment device are connected, so that the working cycle of the treatment device and the Air filter devices are matched to one another «

The screen cylinder is expediently arranged in a housing, and under the screen cylinder there can be a collecting box, which can be pulled out of the housing, for those removed from the screen cylinder Foreign matter may be provided. The brush or brushes can be interchangeably arranged in this collecting box be.

In the case of a treatment device with switching mechanisms provided on both end faces of its housing, it is preferred one air filter device in each of the built-on parts of the housing provided in accordance with the utility model and in the middle between the symmetrically and coaxially arranged Screen cylinders coaxially to these one provided at both shaft ends with a suction fan ' Electric motor arranged.

The drawing shows a device for treating textile goods with an air filter device according to the utility model for example shown. Show it:

1 shows a section through an air filter device according to FIG the line I-I of Figo 5,

2 shows an axial section through an air filter device according to the line H-II of Figo 1,

Fig. 3 an overrunning clutch,

4 shows the end face of a device for treating textile goods with an air filter device according to FIG the utility model,

FIG _e 5 is a view of the treatment apparatus according to Fig _O 4.

The air filter device is described below for a better explanation of its mode of operation in connection with a device for treating textile goods, which in the example shown is one in which a perforated drum 2 with its hollow pin J is rotatably mounted in a housing 1, through which a Desiccant, for example warm air, can be introduced, which can escape again from the housing 1 through one or more pillars 4 _{or the like}

A screen cylinder 5, the circumference of which is formed by a screen 6, is rotatably mounted in such a nozzle 4 its otherwise closed interior with a seal

is connected to an air outlet line 7. One or several cleaning brushes 8 for the sieve 6 are fixed to the frame in one or several surface lines of the cylinder 5 arranged »The screen cylinder 5 is in the rhythm of a Switching mechanism which is provided on the device for treating textile goods to partial rotations, for example each rotated by 60 ° around its axis.

The drum 2 of the device is driven by a motor 9 and has an opening through one of the Drum circumference adapted, in the drum interior pivotable shell 10 is closable. An opening of the housing 1 can be closed by a cover 11 which can be opened and closed and which can be pivoted by means of a shaft 12 a double-armed lever 13 is firmly seated. The shaft 12 is controlled by a cylinder-piston unit 15, which also still other punctures of the device, e.g. opening and closing the shell 10 at appropriate times can control o

On the shaft 16 of the screen cylinder 5 sits firmly the Gätriebe Part of an overrunning clutch, in the example shown, the ratchet 17 of a ratchet 18, while the driving Part 19 of the ratchet 18 is rotatably arranged on the shaft 16 »He has in a known manner an under action Spring 20 standing pawl 21, firmly connected to

the driving part 19 of the ratchet 18 is a lever 22, which has a push rod 23 with one end of the double-armed Lever 13 is connected. Each time the! Lid is opened or closed, in the example shown, when the lid is closed, the ratchet 18 is operated in the sense that it engages the shaft 16 of the screen cylinder 5 rotates a partial turn »

As a result, the fibers or fiber flocks that have settled on the outside of the sieve 6 pass through the brushes stripped »

Under the screen cylinder 5 there is a collecting box 24 which can be pulled out of the housing 1 for those removed from the cylinder 5 Pipes or fiber flakes provided. In the example shown, the brushes 8 are interchangeable in FIG this collecting box 24 is arranged.

In the case of larger devices for treating textile goods, the arrangement can be made so that on both

w-

Ends of the device, which in this case is provided with a switching mechanism 12,13,14,15 on each end face, one air filter device in each socket attached to the housing 5.8 is provided and that in the middle between the symmetrically and coaxially arranged Sieiizylindern 6 coaxial to this one on both shaft ends 27 with one. Electric motor provided with suction fan 25 26 is arranged ο
