Description

(1) The invention is described with reference to two embodiments, and in the drawings:

(2) FIG. 1 shows a first embodiment of the washing machine according to the invention comprising two washing drums, each having a film which can be tensioned on one side,

(3) FIG. 2 shows a washing machine comprising two washing drums, each having a film which can be tensioned on both sides.

(4) FIG. 1 shows two drums 1, 2 which are arranged adjacent to one another and functionally connected one after the other, and are rotatable about a respective horizontal axis of rotation 10,11 in a longitudinal direction L. Chambers 101, 102, 103, 104, 105, 106, 107, 108, 109 or 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, which in each case extend over an entire longitudinal extent of the drums 1, 2, are in each case oriented in the longitudinal direction L along the outer circumference of each of the two drums 1, 2. Each of the chambers 101, 102, 103, 104, 105, 106, 107, 108, 109 or 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210 is delimited in the circumferential direction by two lateral closed lamellas 3, 4. The drums 1, 2 have for example a length of two metres and a diameter of just one metre. One, two or more longitudinal profiled sections 5 can be inserted into each of the chambers 101, 102, 103, 104, 105, 109 or 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210. The washing machine in FIG. 1 has a receiving opening 6 on the extreme left for the individual longitudinal profiled sections 5. The drum 1 has an outlet opening 7, out of the longitudinal profiled section 5 can roll automatically via a receiving opening 8 of the further drum 2 and into the chamber 200 of the further drum 2. The further drum 2 likewise has an outlet opening 9 for the individual longitudinal profiled sections 5.

(5) The chambers 101, 102, 103, 104, 105, 106, 107, 108, 109 are open externally in the radial direction and in the washing machine according to the invention they are preferably closed towards the exterior in a watertight manner by a flexible film 21, and the chambers 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210 are open externally in the radial direction and are preferably closed towards the exterior in a watertight manner by a further flexible film 30. Each of the two films 21, 30 has two long edges 22, 23 or 31, 32 in each case which are provided in each case with a tensioning support 24, 25 or 33, 34.

(6) The following description is confined to the drum 1 in FIG. 1. However, it can be applied analogously to the further drum 2.

(7) The drum 1 in FIG. 1 rotates clockwise in the direction of rotation R. The chambers 100, 101, 102, 103, 104, 105, 106, 107, 108, 109 of the drum 1 are equipped with longitudinal profiled sections 5, and the longitudinal profiled sections 5 rotate along a transport path, which is provided above the axis of rotation 10 of the drum 1, to the outlet opening 7 of the drum 1. A plurality of washing fluid nozzles (not shown) are provided on an end face of the drum 1. The washing fluid nozzles are arranged on the end face of the first four chambers 102, 103, 104, 105 which are completely closed radially towards the exterior in the direction of rotation R. All chambers 100, 101, 102, 103, 104, 105, 106, 107, 108, 109 of the drum 1 are open on both end faces. Through the washing fluid nozzles a washing fluid is sprayed under pressure via the open end face through the chambers 102, 103, 104, 105 in the longitudinal direction L of the chambers 102, 103, 104, 105, so that the longitudinal profiled sections 5 arranged in the chambers 102, 103, 104, 105 are washed. The washing fluid from the chambers 102, 103, 104, 105 flows out again from the chambers 102, 103, 104, 105 which are likewise open on the opposing end faces. In the direction of rotation R, downstream of the washing nozzles, blow drying nozzles are provided on the end faces of the subsequent chambers 106, 107, 108. The blow drying nozzles are provided on the end face of the last three chambers 107, 108 before the outlet opening 7 of the drum 1. The washing fluid may be water or water with additives, such as for example corrosion inhibitors, oil or other additives. The washing fluid compositions of the one drum 1 and the further drum 2 can be the same or different.

(8) Each of the chambers 100, 101, 102, 103, 104, 105, 106, 107, 108, 109 of the drum 1 is delimited laterally by a leading lamella 4 and a trailing lamella 3. In terms of their height the lamellas 3, 4 extend substantially in the radial direction. However, they have a slight inclination in the direction of rotation R, which makes it possible that the cross-sectionally round, preferably cross-sectionally circular longitudinal profiled sections 5 can roll out of the chamber 109 automatically in the region of the outlet opening 7.

(9) The film 21 can be a plastic film, for example a polyethylene film, which has a thickness of 1 to 6 mm, preferably 1 to 3 mm, particularly preferably precisely 3 mm. The film 21 is flexible, but is not or only slightly elastic. The film 21 is cut to a substantially rectangular shape. Each of the tensioning supports 24, 25 extending along the entire long edge 22, 23 is provided along each of the long edges 22, 23 of the film 21 extending in the longitudinal direction L. The tensioning supports 24, 25 are tensioning supports 24, 25 which are adapted in the longitudinal direction L to the length the one drum 1, and in which the respective long edges 22, 23 of the film 21 gripped or firmly screwed or fastened in some other way.

(10) In FIG. 1 one long edge 22 of the film 21 is connected to the tensioning support 24 which is fixed in position relative to a frame 28 of the washing machine, whilst the second long edge 23 of the film 21 is connected to the tensioning support 25 which is movable relative to the frame 28. The tensioning support 25 is fastened to a tensioner 26, which tensions the film 21 along the transport path of the longitudinal profiled sections 5 under continuous tension on the outer circumference of the drum 1, so that the film 21 rests on outer lamella edges 3a, 4a of the individual lamellas 3, 4 and the lamellas 3, 4 slide internally over the film 21 during the rotary movement of the drum 1. In this case, however, the film 21 rests closely and, due to the exerted tensioning force, firmly on the lamellas 3, 4, so that the washing fluid flowing through the chambers 102, 103, 104, 105 cannot flow out of the chambers 102, 103, 104, 105 laterally in the radial direction via the lamella edges 3a, 4a.

(11) The washing machine illustrated in FIG. 1 enables the first washing and drying in the drum 1, and in the further drum 2 the further washing and further drying of the individual longitudinal profiled sections 5, which are then transported away from the washing machine by means of a conveyor 40.

(12) The second embodiment according to FIG. 2 has a corresponding construction to the first embodiment, and the same references signify the same features.

(13) However, each of the two films 21, 30 is provided on both long edges 22, 23, 31, 32 with a respective one of the tensioning supports 24, 25, 33, 34, although the tensioning supports 24, 25, 33, 34 of the two films 21, 30 are coupled to the tensioner 26 or the tensioners 27, 35, 36 respectively, so that by combined adjustment of the two tensioners 26, 27, or 35, 36 of each of the two drums 1, 2 a displacement of both the one film and also the further film 21, 30 by means of the one or the further drum 1, 2 along the respective circumferential direction is made possible, wherein the once the film 21, 30 has been set in its angular position it then remains fixed in position relative to the frame 28.

(14) The two tensioners 26, 27 or 35, 36 of the film 21 or of the further film 30 make it possible to lower the films 21, 30 at the respective outlet opening 7, 9 to such an extent, and to configure the outlet openings 7, 9 to be so narrow in terms of their height, that they are only slightly higher than the diameter of the longitudinal profiled section 5, so that the longitudinal profiled section 5 does not fall out of the chamber 109 of the drum 1 too early, but only rolls out of the chamber 109 of the drum very late and is transferred to the chamber 200 of the further drum 2 or rolls out of the chamber 210 of the further drum 2 and is transferred to the conveyor 40.
