Definitions
- the invention relates to a multi-bale opener with a fiber pressed bale leading to a horizontal removal plane, transversely guided to the removal level transport device and a removal device moved to and fro in the removal level, and a method for opening and mixing different fiber pressed bales.
- bale opening device is known from DE-OS 20 61 044, according to which the fiber press bales set up in bale rows can be continuously pushed in the longitudinal direction thereof during processing.
- the opening device can be moved back and forth along a straight guide relative to the rows of bales, while the fiber material is fed along an ascending ramp.
- Such a multi-bale opening system has the disadvantage that it can only process batches of raw material that are uniform in size.
- Cotton blends from different provenances have considerably different bale dimensions, so that manual height compensation must take place before the intended cotton blend can be processed on the known multi-bale opening system.
- the height differences are compensated for by separating an upper section from higher bales and placing them on the lower bales.
- this considerably varies the mixing ratio in the batch.
- Another disadvantage is that mixing ratios can only be set in the form of integer bale number ratios, namely within the scope of the bales processed simultaneously on the ramp.
- the invention is based on the object of developing a multi-bale opener and a method for opening and mixing different fiber pressed bales in such a way that an arbitrarily selectable mixing ratio which can be changed at any time can be set.
- the transport device according to the invention with a plurality of mutually independent transport tracks arranged next to one another makes it possible, for example, to transport different cotton provenances with different bale dimensions to each transport track; a desired mixing ratio of any desired can be set with high accuracy via the transport speed. It is essential that this mixing ratio is infinitely adjustable and can be changed at any time. For example, it is possible to put together different lots with one bale feed without interrupting the processing process. In order to change the mixing ratio, it is not necessary to change the bale arrangement.
- any mixing ratio between the four bale rows can be set, for example 12.5% first bale row, 45% second bale row, 21% third bale row and 21.5% fourth bale row.
- Mixing ratios of this type could not previously be set, since the composition of the mixture relied on the quantitative ratio of simultaneously processed whole bales.
- Each transport path can be raised in such a way that each fiber bale at the beginning of the removal surface has the same height with its upper edge as the adjacent rows of bales. Due to the different angle of the individual transport tracks to the removal level, a different dosing stroke results, assuming the same transport speeds, but this can be compensated for by setting corresponding transport speeds.
- the removal device can be moved back and forth parallel to the transport direction in the region of the removal surface, the length of the removal device corresponding to the width of all transport tracks transverse to the transport direction.
- the removal device e.g. a milling device, guided parallel to the transport direction.
- the method for opening and mixing different fiber pressed bales is characterized according to the invention by feeding a plurality of fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed via a uniform bale height and the setting of a specific mixing ratio from the feeds fed into the individual transport lanes Fiber pressed bales or fiber pressed bale mixtures via the transport speed of the individual transport webs.
- the method according to the invention advantageously provides that the individual fiber press bale rows are fed at different speeds, whereby the mixing ratio between the individual fiber press bale rows can be set exactly.
- a uniform ramp angle of the individual transport tracks is provided. As a result, lower bales enter the removal area at a later point in time, but this can be compensated for by a higher transport speed.
- a plurality of fiber-pressed bale rows of different heights are arranged next to one another by varying the ramp angle for each transport track. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
- the individual fiber pressed bale rows can themselves contain a bale mix of equal high pressed bales, the number of mixable fiber pressed bales depending on the number of fiber pressed bales that can be processed simultaneously in the removal area in the direction of transport.
- Fig. 1 a multi-bale opener according to the invention in
- Fig. 2 shows a cross section through the multi-bale opener along the line II-II in Fig. 1st
- the multi-bale opener 1 has a transport device consisting of a plurality of transport tracks 2, 4, 6, 8 arranged parallel to one another and which, in the exemplary embodiment of the drawings, can accommodate four rows of bales 10, 12, 14, 16 next to one another.
- the individual conveyor tracks 2, 4, 6, 8 preferably consist of endlessly driven conveyor belts which run essentially horizontally in a section 18 at the front in the transport direction, on which the batch can be placed, and in a section 20 in the manner of a ascending ramp in the region of a removal surface processed by the removal device 5 so that the end section of the treadmill reaches as far as the removal level of the removal surface 3.
- the transport tracks 2, 4, 6, 8 are held in bearings 23 at this upper end of the treadmill so as to be pivotable about a common axis of rotation, the lower end of the inclined transport tracks 2, 4, 6, 8 being raised in this way depending on the height of the bales presented can that the upper edges of the respective rows of bales presented enter the removal level of the removal surface 3 at the same height.
- the transport tracks 2, 4, 6, 8 are preferably subdivided one or more times, the last subdivision being provided at the beginning of the removal surface 3.
- the divided transport tracks 2, 4, 6, 8 can, as can be seen from FIG. 1, be coupled to one another via a toothed belt or the like.
- the front transport track section 18 is also pivotally mounted at its front end in the transport direction in order to raise the bale rows 10, 12, 14, 16 differently to enable already in the first transport track section 18 and to enable a virtually stepless transition to the last transport track section 20.
- the transport tracks are lifted in the area of the removal surface by means of a lifting device 22, for example linear motors such as hydraulic piston-cylinder units, which, as can be seen, for example, from FIG. 2, can be arranged in pairs to the side of the transport tracks 2, 4, 6, 8, and are ein ⁇ tellbar with an appropriate control device to a desired 'level. Similar lifting devices can also be provided for the front transport track section 18.
- the rows of bales 10, 12, 14, 16 arranged next to one another, as can be seen in FIG. 2, are guided from side support walls to the end of the ramp formed by the transport tracks 2, 4, 6, 8.
- the removal surface 3 covers approximately the length of four bales arranged one behind the other within each row of bales 10, 12, 14, 16 in the transport direction.
- the removal device 5 is shown in FIG. 1 in its rear end position in the transport direction, with each time the removal device 5 is moved back and forth, the total of 16 bales located on the ramp are processed in accordance with their delivery.
- the removal device 5 essentially consists of two milling rollers 26, 27 rotating in opposite directions, which fling the removed fiber flakes upwards between them into a suction chamber 28, from which they pneumatically be transported away via a suction line 30.
- the removal device 5 is guided in a straight line over the removal surface 3 with the aid of a roller / rail construction 32, 34.
- bales can be placed on the individual transport tracks with regard to their height, different dimensions. This makes it possible, e.g. To mix cotton bales of different provenances with one another in any desired mixing ratio.
- the mixing ratio can namely be set in a simple manner via the delivery speed of the conveyor belts, so that in the embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
- bale feed it is also possible to change the batch to another mix without any problems, without having to replace the bale feed.
- the new mixture should only contain cotton provenances that are contained in the bale rows 10, 14 and 16, it is also possible to stop the transport path of the bale row 12.
- the multi-bale opener 1 thus opens up the possibility of assembling and processing different batches with different mixing ratios using a uniform bale template.
