Definitions

  • the invention relates to a method for removing fiber flakes according to the preamble of the first method claim and to a control according to the preamble of the first control claim.
  • a control system according to the preamble of the first control claim is known from German Offenlegungsschrift No. 32 45 506.
  • This machine travels in a straight line back and forth over a textile fiber bale group and removes fiber flakes from the bales with a rotating removal roller. So that the removal roller can penetrate the bale surface with different force and this force can be adjusted taking into account the different bale height and thus the different bale density, three vertically arranged limit switches with variable mutual spacing are provided, which are switched by the removal element that is lowered during removal.
  • Each limit switch controls a pneumatic changeover valve, which pre-routes the path for compressed air releases the pressure into an air cylinder.
  • the piston rod of the compressed air cylinder is connected to this in the middle part of a rope. In front of and behind this connection point, the rope is guided over a deflecting roller, with the removal member being attached to one end of the rope hanging from the deflecting rollers and a counterweight compensating the weight of the removal member being attached to the other.
  • the removal device would remove fiber flakes at a predetermined constant pressure controlled by the upper limit switch until the middle bale layer was reached.
  • the middle limit switch for the removal of this layer, causes an increased constant pressure compared to the previous one, and when the lower layer is reached, the lower limit switch again causes a constant pressure, reduced for the removal of these layers.
  • Another disadvantage is that only one bale group with bales of the same height can be removed, otherwise the limit switch position would have to be continuously adjusted to the different heights.
  • the invention is therefore based on the object of eliminating these disadvantages.
  • the object was achieved according to the invention by the method steps listed in the characterizing part of the first method claim and by the control steps listed in the characterizing part of the first control claim.
  • the advantages achieved by the invention lie in the fact that by using a microprocessor, adjustments to the removal depths can be carried out very quickly and easily.
  • a machine 1 for removing fiber flakes comprises a removal device 2, a machine frame 3 and a flake transport 4.
  • the removal member 2 itself comprises a housing construction 5, in which a rotating removal roller 6 is drivably mounted.
  • a rotating removal roller 6 By means of this housing construction 5, the fiber flakes removed from the fiber bales 7 by the removal roller 6 are further picked up and further conveyed into the flake transport 4 by ways not shown.
  • the housing construction 5 can be moved up and down in the direction of arrow A by means of rollers 9 which are rotatably fastened to it and guided in guide rails 8 of the machine frame 3.
  • rollers 9 which are rotatably fastened to it and guided in guide rails 8 of the machine frame 3.
  • guide rails 8 of the machine frame 3.
  • only one pair of rollers and only one rail 8 is shown; the rollers and rails provided on the opposite side in the same way are not visible.
  • the housing construction 5 has a driver 10 which is firmly connected to a chain 11 of a chain drive 12.
  • the chain drive 12 further comprises an upper, rotatably mounted sprocket 13 for deflecting the chain 11 and a lower sprocket 14 for driving this chain 11.
  • the lower sprocket 14 is rotatably mounted on a drive shaft 15 of a transmission 16.
  • the chain drive 12, the transmission 16 and the electric Motor 17 are referred to as a whole as a lifting device.
  • the motor 17 On the upper shaft end 18, as seen in the direction of the figure, the motor 17 has a gear 19 rotatably mounted, which functions as a counting wheel together with an initiator 20 as a pulse generator, the pulses of which are fed via a line 21 to a microprocessor 22.
  • the initiator 20 is commercially available and gives an impulse for each tooth of the gear 19 that passes.
  • the initiator 20 is provided to be stationary.
  • An upper limit switch 23 and a lower limit switch 24 are provided on the machine frame 3 for scanning the upper and lower end positions of the removal member.
  • the upper limit switch 23 is actuated by an upper surface 25 and the lower limit switch 24 by a lower surface 26 of the driver 10.
  • the upper limit switch 23 inputs its pulse via a line 27 and the lower limit switch 24 via a line 28 into the microprocessor 22.
  • a light barrier with a transmitter 30 and a receiver 31 is provided on the lower side 29 of the housing construction 5 facing the fiber bale 7, which is arranged such that the transmitter extends a light beam 32 that extends at least over the entire length L of the removal roller 6 generated, which is converted in the receiver into a signal supplied to the microprocessor 22 via a line 33.
  • Another line 34 connects the electric motor 17 to the microprocessor 22.
  • the machine frame 3 is arranged by means of drivable and drivable wheels 35 on rails 36, which are fastened on the spinning floor 37, along the fiber bale 7 (not shown) and can be moved over the flake transport 4.
  • the fiber bales 7 are assembled in groups (not shown) in a manner known per se, in such a way that bales of essentially the same height are arranged together and a distance of 1.2-1.5 m is maintained between the bale groups.
  • an initiator 38 on the underside of the machine frame and, on the other hand, so-called position elements 39 are provided over the entire length on which the machine 1 can be moved are slidably arranged on a rail 40. The presence of these position elements 39 is determined by the initiator 38 and reported to the microprocessor via a line 41.
  • the aforementioned end positions are to be understood, on the one hand, as the starting position of the machine at the start of the rail, from which the movement of the machine is started, and, on the other hand, as the end position at which the machine changes the direction of travel.
  • the positioning elements 39 are set in such a way that the machine is stopped in such a way that the removal member is located in front of the first or behind the last or between the individual bale groups.
  • the bale height is divided into 3 to 4 zones. In our example there are four zones labeled A, B, C and D.
  • the removal depth for zone B is calculated by the microprocessor. It is gradually reduced during the number of passes entered from the removal depth of zone A to the removal depth of zone C.
  • the height Hb results from the microprocessor's calculation.
  • the weight of the entire bale feed and the desired hourly production can be entered for zone C instead of the removal depth per run (from these two data and the bale height, the microprocessor calculates the removal depth for all bale groups so that they are completely removed at the same time).
  • the removal depth of the last pass and the number of passes in zone D are entered. During these passes, the depth of cut is gradually increased from the depth of zone C to the depth of the last pass. From this, the microprocessor 22 calculates the height Hd of the zone D and thus the beginning of the removal depth again increased in this zone.
  • the height Hc of the zone C results from the total height minus the height Ha, the height Hb and the height Hd.
  • the machine is started to be removed by pressing an start button (not shown) by an operator.
  • the machine 1 With the removal device 2 in the upper end position (with actu the upper limit switch 23, the machine 1 moves from the starting position on the rails 36 over the bales 7 placed on the floor 37. After passing over the first positioning element 39, which is reported by the initiator 38, the machine continues for a few seconds, so that the removal device is located above the bale group. Subsequently, the removal member 2 lowers due to a control command of the microprocessor 22 sent to the motor 17 via the line 34 until the light beam 32 is interrupted by the bale group.
  • the pulses caused by the gearwheel 19 are again continuously counted in the microprocessor from the total pulse sum, so that the height of this bale group is determined when the ablation element 2 is at a standstill as a result of the interrupted light beam 32.
  • the machine 1 automatically continues until the next positioning element 39 is ascertained. The machine then stops in an analogous manner, and the removal member 2 moves back to the upper end position. After the machine 1 has moved so far over the last-mentioned positioning element 39 that the removal member is again above the bale group, the height of this bale group is again determined in the prescribed manner. The same happens for all other bale groups.
  • the removal device is used to remove the fiber flakes the bale surfaces, before each pass over a bale group by the value entered or calculated by the microprocessor of the removal depth. These removal depths can be different for each bale group depending on the respective bale height.
  • the microprocessor automatically switches the removal depth for removing one bale zone to the removal depth for the next bale zone.
  • the removal depths and the passages and thus the zone heights can be changed at any time without interrupting the removal process.
