Definitions

  • the invention relates to a method and a device for removing fiber flakes from textile fiber bales according to the preamble of the first and fourth claims and to two uses of the method, a use of the device in a machine for removing fiber flakes and a controller for using the machine .
  • a bale removal machine of the "UNIFLOC" brand from the applicant is known in practice, in which a removal device is arranged on a lifting device which can be moved back and forth along the bale for removing fiber flakes from textile fiber bales of different bale heights and / or different fiber types.
  • the removal device comprises a fiber removal member which extends between grate bars and projects beyond them by a predetermined amount.
  • the grate bars When the fiber flakes are removed, the grate bars also protrude, but less by the amount mentioned, into the surface layer of the fiber bales than the removal member.
  • the protrusion of the removal element into the surface layer is called the removal depth and can vary depending on the removal rate.
  • the invention is therefore based on the object of obtaining an optimization of the removal that takes into account the fiber types.
  • the advantages achieved by the invention lie in the possibility of carrying out a removal which takes into account the type of fiber of the individual bales. Another advantage is that an optimization of the removal is possible taking into account the removal rate, the density of the surface layer and the type of fiber, specifically for each bale or group of bales.
  • a device 1 for removing fiber flakes (not shown) from fiber bales 2 comprises a fiber removal member 3 in the form of a rotatable shaft 5 equipped with toothed disks 4.
  • a housing 6 with the housing walls 7 and 8 surrounds the fiber removal member 3 in such a way that fiber flakes (not shown) removed from the fiber bales 2 (for example) in the direction of the arrow F if the removal member is in the direction of the arrow E or in the direction of the arrow G if the removal member is in the direction of the arrow H rotates, can be conveyed into the pneumatic flake conveying channel 9 formed by the upper part of the housing 6.
  • the toothed disks 4 reach between grate bars 10 and protrude over these grate bars 10 by a predetermined amount M.
  • the grate bars 10 also protrude, but by the amount M less deeply into the surface layer of the fiber bales 2.
  • the grate bars 10 are fastened to side members 11 and 12, the height of which can be adjusted by means of threaded spindles 13.
  • the spindles in turn are extended shafts of gear stop motors 14, which, respectively, by means of a bracket 15 on the walls 7. 8 are supported.
  • two threaded spindles 13 are provided for the longitudinal beams 11 and 12.
  • a simpler embodiment, not shown, consists in that only one gear stop motor is used and the overdrive from this motor to the other three spindles 13 takes place, for example via a chain overdrive known per se.
  • the shaft 5 is rotatably supported at one end in a bearing 17 fastened to an end wall 16 of the housing 6 and connected to a drive (not shown) at the other end.
  • a grate 10 is present on both sides of the toothed disks 4.
  • the fiber removal member 3 is also the possibility of designing the fiber removal member 3 to be adjustable instead of the grate bars, for example if the bearings accommodating the shaft 5 were arranged to be displaceable.
  • the removal device 1 is moved back and forth over the fiber bales 2 in the directions denoted by R.
  • FIG. 3 shows a machine 20 for removing fiber flakes from textile fiber bales 2, in which the removal device 1 is used.
  • the machine 20 comprises a machine frame 21 and a flock transport 22.
  • the transport routes and transport devices from the flock conveying channel 9 to the flock transport port 22 are not shown and are not the subject of the invention.
  • the removal device 1 can be moved up and down in the direction of the arrow N by means of rollers 24 rotatably fastened to it and guided in guide rails 23 of the machine frame 21.
  • rollers 24 rotatably fastened to it and guided in guide rails 23 of the machine frame 21.
  • guide rails 23 of the machine frame 21.
  • only one pair of rollers and only one rail 23 are shown in the figure; the rollers and rails provided on the opposite side in the same way are not visible.
  • the removal device 1 has a driver 25 which is firmly connected to a chain 26 of a chain drive 27.
  • the chain drive 27 further comprises an upper, rotatably mounted sprocket 28 for deflecting the chain 26 and a lower sprocket 29 for driving this chain 26.
  • the lower sprocket 29 is rotatably mounted on a drive shaft 30 of a transmission 31.
  • the machine frame 21, the guide rails 23, the chain drive 27, the gear 31 and the electric motor 32 are referred to as a whole as a lifting device.
  • the motor 32 On the upper shaft end 33, as seen in the direction of the figure, the motor 32 has a gear 34 fixed in rotation, which functions as a counting wheel together with an initiator 35 as a pulse generator, the pulses of which are fed to a microprocessor 37 via a line 36.
  • the initiator 35 is commercially available and emits a pulse on each tooth of the gear 34 passing by.
  • the initiator 35 is provided to be stationary.
  • an upper limit switch 38 and a lower limit switch 39 are provided on the machine frame 21.
  • the upper limit switch 38 is actuated by an upper surface 40 and the lower limit switch 39 by a lower surface 41 of the driver 25.
  • the upper limit switch 38 inputs its pulse via a line 42 and the lower limit switch 39 via a line 43 into the microprocessor 37.
  • a light barrier with a transmitter 45 and a receiver 46 is provided on the lower side 44 of the removal device 1 facing the fiber bale 2, which is arranged such that the transmitter generates a light beam 47 extending at least over the entire length of the fiber removal member 3 which is converted in the receiver into a signal supplied to the microprocessor 37 via a line 48.
  • Another line 49 connects the electric motor 32 to the microprocessor 37.
  • the machine frame 21 is arranged to be movable along rails (not shown) and over the flock transport 22 by means of wheels 50 fastened and drivable on rails 51, which are fastened on the spinning floor 52.
  • the fiber bales are assembled in groups (not shown) in a manner known per se, in such a way that bales of substantially the same height are arranged together and a distance of 1.2-1.5 m is maintained between the bale groups.
  • an initiator 53 on the underside of the machine frame and on the other hand so-called position elements 54 are provided over the entire length on which the machine 20 can be moved are slidably arranged on a rail 55. The presence of these position elements 54 is determined by the initiator 53 and reported to the microprocessor via a line 56.
  • 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 54 are set in such a way that the machine is stopped in such a way that the removal member is in front of the first or behind the last or between the individual bale groups.
  • the bale height is divided into three to four zones. In our example there are four zones labeled A, B, C and D.
  • the removal process now begins as follows:
  • the removal member travels from the upper limit switch 38 to the lower limit switch 39.
  • the microprocessor counts the impulses caused by the gear 34 on the initiator and thus knows the sum of all impulses or the distance between the lower and upper end positions.
  • microprocessor for removal must then be programmed as follows:
  • the microprocessor 37 is given the removal depth predetermined for zone A per passage of the removal member via the bale group and the number of passes to be carried out with this removal depth, which gives the height Ha.
  • the removal depth for zone B is calculated by the microprocessor. It is reduced step by step 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.
  • the microprocessor calculates the removal depth for all bale groups in such a way that they are completely removed simultaneously.
  • the removal depth of the last pass and the number of passes of the zone D 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 37 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 corresponding dimension M is programmed into the microprocessor 37, so that with the corresponding signaling by the corresponding positioning element 54, the dimension M is adapted to the fiber material of the bale group or bale to be removed.
  • the machine is started to be removed by pressing an start button (not shown) by an operator.
  • the removal device 1 With the removal device 1 in the upper end position, when the upper limit switch 38 is actuated, the machine 20 moves from the starting position on the rails 51 over the bales 2 set up on the floor 52. After passing over the first positioning element 54, which is reported by the initiator 53 the machine continues for a few seconds so that the removal device is located above the bale group. Subsequently, the removal device 1 lowers due to a control command of the microprocessor 37 sent to the motor 32 via the line 49 until the light beam 47 is interrupted by the bales.
  • the pulses caused by the gearwheel 34 are again continuously counted in the microprocessor from the total sum of pulses, so that when the ablation device 1 is at a standstill as a result of the interrupted light beam 47, the height of this group of bales is determined.
  • the machine 20 automatically continues until the next positioning element 54 is ascertained. The machine then stops in an analogous manner and the removal device 1 moves back into the upper end position. After the machine 20 has moved so far over the last-mentioned positioning element 54 that the removal device is again above the bale group, the height of this bale group is again determined in the aforementioned manner. The same happens for all other bale groups.
  • the removal device for removing the fiber flakes from the bale surfaces is lowered before each pass through a bale group by the value of the removal depth entered or calculated by the microprocessor. 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 group to the removal depth for the next bale group and changing the dimension M.
  • the removal depths and the passages and thus the zone heights can be changed at any time without interrupting the removal process. The same applies to changing the size M.
  • the flock transport 22 can either be a pneumatic conveying channel (FIG. 3) or a conveyor belt (not shown) or some other suitable conveying means for flakes.
  • the lifting device can also consist of other elements which can be used for lifting and lowering the removal device 1; it is not limited to the elements shown.
