Definitions

  • the invention relates to a multi-bale opener with a fiber pressed bale to a horizontal removal plane leading to the removal level and a transversely guided in the removal level removal device, 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 fiber pressed bales set up in rows of bales 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 very different bale dimensions, so that manual height adjustment 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.
  • the object of the invention is to develop 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 onto each transport track.
  • Any desired mixing ratio 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 use a bale template to put together different lots 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 was dependent on the quantitative ratio of whole bales processed simultaneously.
  • Each transport path can be raised in such a way that each fiber pressed bale has the same height as the adjacent bale rows at the beginning of the removal surface with its upper edge. Due to the different angle of the individual transport tracks to the removal level, a different metering 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 ablation 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 several fiber pressed bales arranged next to one another on separate transport lanes, fiber pressed bales or a fiber pressed bale mixture being fed to a uniform bale height via each transport lane and the setting of a specific mixing ratio from the fiber pressed bales supplied in the individual transport lanes or Fiber bale mixes on the transport speed of the individual transport lanes.
  • the method according to the invention advantageously provides that the individual rows of fiber pressed bales are fed at different speeds, whereby the mixing ratio between the individual rows of fiber pressed bales 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 path. This ensures that all four rows of fiber pressed bales can be processed over the entire removal area.
  • the individual rows of fiber pressed bales can themselves contain a bale mixture of fiber bales of the same height, the number of mixable fiber pressed bales depending on the number of fiber pressed bales which can be processed simultaneously in the removal surface in the direction of transport.
  • 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 can accommodate four rows of bales 10, 12, 14, 16 next to one another in the exemplary embodiment of the drawings.
  • the individual transport 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 rear section 20 in the manner of an ascending ramp rise in the area of a removal surface machined by the removal device 5 such 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 manner 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.
  • a lifting device 22 e.g. 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 can be adjusted to a desired height using a suitable control device. 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 consists essentially of two counter-rotating milling drums 26, 27, which fling the removed fiber flakes upwards between them into a suction chamber 28, from which they are pneumatic can be removed 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 respect to their height of different dimensions. This makes it possible, e.g. Mix cotton bales of different origins with each other in any mixing ratio.
  • the mixing ratio can namely be adjusted in a simple manner via the feed speed of the conveyor belts, so that in the exemplary embodiment according to FIG. 2 four different qualities can be processed with any mixture and constant mixing ratio.
  • 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.
