FIBRE GUIDE INSERT FOR AN OPENING ROLLER HOUSING

Abstract

A fibre guide insert for an opening roller housing, with an insert body to be pushed into a mounting opening of the opening roller housing, the insert body having a fibre guide surface forming a fibre channel inlet and a fibre channel connection section connected to a fibre channel input. An opening roller housing for an opening device of an open-end rotor spinning device, having a fibre channel leading into an opening roller housing interior, where it adjoins a fibre channel input for fibres, and a mounting opening for a fibre guide insert, which mounting opening is open towards the opening roller housing interior. In order to provide a fibre guide insert for an opening roller housing, which provides a suitable fibre channel inlet area in a simple way according to the fibres to be processed, there is provision for the fibre channel connection section to be formed on an end face of the insert body and the fibre guide surface running in the direction of the longitudinal axis of the insert body to adjoin the fibre channel connection section. In order to provide an opening roller housing, of which the fibre guide surface adjoining the fibre channel is easily adapted to the specific application, there is provision for the mounting opening to run parallel to the tangent of an opening roller arranged in the opening roller housing interior and the mounting opening to be configured in such a way that an insert body of a fibre guide unit to be pushed into the mounting opening is connected to the fibre channel input with a fibre channel connection section arranged on the insert body on the end face, in which case the insert body is pushed into the mounting opening via an outer opening of the opening roller housing.

Claims

3. The fibre guide insert according to claim 1, characterised in that the fibre channel connection section runs at an angle to the longitudinal axis of the insert body.

4. The fibre guide insert according to claim 1, characterised in that the insert body has a guide element on its peripheral surface to be brought into engagement with a guide element mount of the mounting opening.

5. The fibre guide insert according to claim 4, characterised in that the guide element is formed by a projection, a groove, a flattening, or a combination which extends in the direction of the longitudinal axis of the insert body.

6. The fibre guide insert according to claim 1, characterised in that the insert body has a fastening for fixing the insert body in the mounting opening.

7. The fibre guide insert according to claim 6, characterised in that the fastening is formed by a magnetic element arranged on the insert body.

8. The fibre guide insert according to claim 1, characterised in that the insert body has a colour coding adapted to the length of the fibre guide surface.

9. An opening roller housing for an opening device of an open-end rotor spinning device, having a fibre channel leading into an opening roller housing interior adjoining a fibre channel input for fibres, and a mounting opening for a fibre guide insert, the mounting opening being open towards the opening roller housing interior, characterised in that the longitudinal axis of the mounting opening runs parallel to a tangent of an opening roller arranged in the opening roller housing interior and the mounting opening is configured in such a way that an insert body of a fibre guide unit to be pushed into the mounting opening is connected to the fibre channel input with a fibre channel connection section arranged on the insert body on the end face, in which case the insert body is pushed into the mounting opening via an outer opening of the opening roller housing.

10. The opening roller housing according to claim 9, characterised in that the outer opening is configured in such a way that an insert body of a fibre guide unit is pushed in parallel to a tangent of an opening roller arranged in the opening roller housing interior or radially to an opening roller arranged in the opening roller housing interior or along an overlap of both directions.

Description

[0028] An embodiment example of the invention explained below with reference to the drawing. In the drawings:

[0029] FIG. 1 shows a perspective view of an opening roller housing with an insert body of a fibre guide unit arranged in a mounting opening; and

[0030] FIG. 2 shows a cross-sectional view of the fibre guide housing from FIG. 1 with the insert body arranged in the mounting opening.

[0031] FIG. 1 and FIG. 2 show an opening roller housing 2 of an opening device of an open-end rotor spinning device not shown here. The opening roller housing 2 has a hollow cylindrical opening roller housing interior 13, the peripheral surface 8 of which is interrupted in sections by a mounting opening 3 extending tangentially to an opening roller axis 14. An insert body 4 of a fibre guide insert 1 is arranged inside the mounting opening 3 in such a way that the insert body 4 with a fibre channel connection section 7 rests against a fibre channel input 6 of a fibre channel 11, which limits the mounting opening 3 in the push-in direction of the insert body 4 into the mounting opening 3.

[0032] The arrangement of the insert body 4 in the mounting opening 3 is such that the fibre channel input 6 and the fibre channel connection section 7 rest against one another in such a way that an inner surface of the fibre channel 11 is flush with a fibre guide surface 5 of the insert body 4, so that the fibre produced in the opening roller housing 2 by an opening roller not shown here can enter the fibre channel 11 from the opening roller housing interior 13 in a trouble-free manner.

[0033] A fibre guide surface 5 of the insert body 4, which essentially perpendicularly adjoins the fibre channel connection section 7, is adapted to the fibres to be processed and the spinning conditions, so that the fibres run into the fibre channel 11 from the opening roller housing interior 13 optimally. By means of the insert body 4, in particular the fibre guide surface 5 of the insert body 4, the fibre channel inlet area arranged in front of the fibre channel 11 can thus be determined specifically for the application.

[0034] The insert body 4 of the fibre guide insert 1 is replaced via an outer opening 15 of the mounting opening 3, via which the insert body 4 is pulled out of the mounting opening 3 and then a suitable insert body 4 is pushed back into the mounting opening 3. To fix the insert body 4 in its position in the mounting opening 3, the insert body 4 has a bore 10, which is designed to receive a fastening screw 9. In the mounted state of the insert body 4 in the mounting opening 3 shown in FIGS. 1 and 2, the screw 9 extends through the bore 10 into a threaded fibre channel bore 12 of the fibre channel 11, through which stable contact of the fibre channel input 6 with the fibre channel connection section 7 is achieved in the set position.

[0035] The fibre guide surface 5 adjoins an area of the insert body 4 curved according to the peripheral surface 8 at the end opposite the fibre channel connection section 7viewed in the peripheral direction of the opening roller housing interior 13. Different insert bodies 4, which are not shown here, vary particularly in length, width and cross section of the fibre guide surface 5.
