Definitions

  • the invention relates to a device for removing fiber flakes from lined-up textile fiber bales with a machine frame which can be moved horizontally back and forth along the fiber bale and a removal member which can be moved downwards and upwards from its end position, on which a horizontally and transversely to the direction of travel stored driven drivable roller is provided.
  • a aforementioned device is known from European patent application EP-A-193647.
  • the inventiveness of this is that the removal depth is changed in the course of the removal in accordance with the density of the fiber bales in order to obtain essentially the same performance with each return trip.
  • the disadvantage of this device is the lack of flexibility in that the removal member can only be moved over the bale in a predetermined position.
  • the object of the invention which is achieved in that the removal member by a parallel pivot axis extending to the removal roller is pivotable in such a way that the lower removal surface of the removal member can be brought into a predetermined inclined position deviating from the horizontal and that if the removal member adopts this inclined position, it moves downward and downward as the machine frame moves back and forth is movable at the top in such a way that the removal takes place in a rising or falling plane.
  • This version of claim 1 is intended to express that only when the lower removal surface has been brought into an inclined position that deviates from the horizontal, by the interaction of the reciprocating machine frame and the removal member that can be moved down and up, the removal of the Fiber bales should take place in an ascending or descending plane.
  • the lower removal surface of the removal member which can be pivoted on a pivot axis, remains horizontal or is pivoted into it in order to remove the fiber bales in the horizontal direction.
  • the advantage of the invention is therefore that with a single device it is possible to remove fiber bales in a purely horizontal direction and (or in an oblique direction. This, as will be mentioned later, allows the removal device to be used in a more versatile manner.
  • a device 1 for removing fiber flakes comprises a removal member 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. Through this housing construction 5, the fiber flakes removed by the removal roller 6 from the fiber bales 7 are received and further promoted into the flake transport 4 via paths not shown.
  • the housing construction 5 can be moved up and down in the direction of the arrow A by means of rollers 9 rotatably fastened to it and guided in guide rails 8 of the machine frame 3.
  • rollers 9 rotatably fastened to it and guided in guide rails 8 of the machine frame 3.
  • Fig. 1 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.
  • a gear 19 is rotatably mounted, which together as a counting wheel works 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, which is arranged such that the transmitter generates a light beam 32 that extends at least over the entire length L of the removal roller 6 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 wheels 35 fastened to it and drivable on rails 36, which are fastened on the spinning floor 37, along the fiber bales 7, in the directions of travel K and M (FIG. 2) and over the flake transport 4.
  • a stop motor 42 is further connected to a gear 47 in the machine frame, which drives said pair of wheels 35 (FIG. 2) via an overdrive 48.
  • a gear 43 is provided on an outward shaft end of the stop motor and an initiator 44 on the stop motor itself.
  • the initiator 44 is connected to the microprocessor 22 via the line 45 and the electric motor via the line 46.
  • the initiator is used to count the teeth passing by in order to detect the position of the device by means of the microprocessor 22.
  • the housing structure 5 is divided into two main parts, namely on the one hand in a sliding carriage 49, to which the driver 10 is attached and a removal roller carrier 50 which is pivotably mounted by means of a pivot bearing 51 provided in the sliding carriage and the pivot axis 52 guided therein and belonging to the removal roller carrier 50.
  • the removal roller carrier 50 is further connected by means of a drive device 53 to a slide shoe 54, which can be moved up and down on a stationary rail 55, as seen in FIG. 2.
  • the slide shoe in turn is fixedly connected to the slide carriage 49 by means of a web 56.
  • the drive device 53 in turn consists of an actuator 57, the shaft of which is provided with a thread 58 which is guided in a threaded sleeve 59.
  • the servomotor 57 is pivotably provided on the sliding block 54 and the threaded sleeve 59 is pivotably provided on a pivot bearing 60 fastened to the removal roller carrier 50.
  • a servomotor is to be understood as a motor which is able to precisely detect the rotary movement of the shaft 58 and to transmit it as a signal to the microprocessor 22 shown in FIG. This makes it possible to move the removal roller carrier 50 into a predetermined inclined position by means of a preselected number of rotations of the spindle 58 (shown in FIGS. 3 and 4). bring to. In such an inclined position, the fiber bales 7 set up in a row are removed, as shown in FIGS. 3 or 4.
  • the microprocessor 22 coordinates the signals of the lines 21 and 45 and accordingly controls the motors 17 and 42 via the lines 34 and 46.
  • an oblique removal between the removal angles ⁇ of 0 ° -60 ° shown in FIGS. 3 and 4 can be realized.
  • angles ⁇ greater than 60 ° are also feasible.
  • positioning elements 39 are provided, which are arranged displaceably on a rail 40. The presence of these positioning elements 39 is determined by the initiator 38 and reported to the microprocessor via a line 41.
  • the removal member 2 works together with a conveyor belt 61, on which the fiber bales are lined up, for removal.
  • the conveyor belt also has a stop motor with gear motor and gear, and initiator (whole drive group not shown), as has been described for the lifting movement of the removal member and for the movement of the machine frame.
  • the signals of the initiator are likewise fed to the microprocessor via a line 62 (only shown in FIG. 1), which delivers the power signals via line 63 (FIG. 1) to the stop motor of the conveyor belt.
  • the removal member leads back a locally fixed path because the fiber bales are fed by the conveyor belt in each case by the necessary removal depth.
  • FIG. 6 shows, in terms of control, a simple, more complex, machine-based variant, in that the machine frame 3.2 has two removal elements 2, respectively, arranged in a line, but protruding in the opposite direction. 2.1, so that when removing in the oblique direction, if every second bale has a quality different from the first, a mixture with four qualities can be carried out.
  • FIGS. 7 and 8 show even further arrangements of the fiber bales, in that a plurality of fiber bales arranged next to one another with different qualities can be removed simultaneously.
  • 7 shows the pivotability of the machine frame 3.1 and the removal member according to the description part for FIG. 5
  • FIG. 8 shows the double removal element arrangement with the machine frame 3.2 according to the description part for FIG. 6.
  • FIG. 9 shows a removal member 2.2 with two removal rollers 6a and 6b. Otherwise, the functions are the same as shown in FIG. 2, which is why the same reference numerals have been used in FIG. 9 for elements with the same functions.
  • portal arrangements can also be used, in which two machine frames 3.3 are each movably arranged on rails (not shown) by means of wheels 35, which are connected by a removal member 2.3.
