Definitions

  • the invention relates to a method and an apparatus for the treatment of Foreign bodies during bale removal according to the generic terms of Claims 1 and 7.
  • the present invention now has the task of automation both foreign body detection and foreign body removal improve.
  • Fig. 1 is a bale removal machine 1 with a rotatable Tower 2 shown with a protruding arm 3.
  • this support arm 3 is, as usual, a removal member 4 shown.
  • a bale removal machine is on and known for itself and is used, among other things, by the machine factory RIETER AG sold under the name UNIFLOC.
  • RIETER AG sold under the name UNIFLOC.
  • the bale removal machine 1 drives over a fiber bale row 9, which here the fiber bales 10 to 13.
  • the bale removal machine 1 runs with - not specified here - roles on one Rail 14 attached to the floor 15 of the spinning room is.
  • the foreign body detection unit 7 shown exists from a thermal camera 16 and a concave mirror 17, which in its focal line has an infrared rod 18.
  • the camera 16 and the tower 2 are connected via lines 19 and 20 to one Computer 21 connected.
  • This computer 21 includes one Keyboard 22 and a printer 23.
  • This part of the bale removal machine 1 is in further detail in FIG EP-A-0412447 precisely drawn and described so that no further details are given here becomes.
  • the foreign body detection unit shown here 7 can also be used in the European Patent application shown in Figs. 1 and 3 be used.
  • the foreign body removal unit 8 from a gripper 24 and a waste container 25, which in more detail with respect to the 2 and 3 are described in more detail.
  • FIG. 2 is a top view in direction A of FIG. 1 indicated schematically. The same became the same for the same elements Reference numerals used.
  • the schematically indicated Carriage 26 guides the gripper, not shown here 24 and runs on a schematically indicated rail 27 in the direction of arrow B across the bale width and forth. If a foreign body has been removed with the gripper 24 is, the carriage 26 continues to the waste container 25 to deposit the foreign body there. Immediately afterwards the carriage 26 moves back into a waiting position for example in the middle of a bale of Bale row 9 is located.
  • the driving speed of the bale removal machine 1 is known to be relatively slow, so that the foreign bodies appearing in the bales without stopping the Bale removal machine can be removed with the gripper 24 can. Only if two foreign objects are too close together the bale removal machine 1 be stopped so the second or subsequent one Foreign bodies can be removed.
  • FIG. 3 is a realistic representation of a gripper 24 presented.
  • Four gripper tongs 28 are included Pins 29 two and two rotatable on a first block 30 attached. Is between two associated gripper tongs 28 a connecting rod 31 attached (only one in Fig. 3 visible). Above the first mounting block 30 is a second block 32 is provided, which has a slide rod 33 is connected to the first block 30. The connecting rod 31 is rotatable via a cross bar 34 with the second block 32 attached.
  • the gripper 24 can thus be of the type a two-rope grab, such as on the Page T15 in the "Dubbel Taschenbuch für den Maschinenbau", 16. Edition in the Springer publishing house has been described.
  • Fig. 4 a variant is shown, which consists of a suction device 35 with a spherical suction cup 36, in which a circular hole 37 is provided centrally for the Suction.
  • This circular hole 37 is harmonica-like movable proboscis 38 connected.
  • This suction cup 36 is thus handled in the same way like the gripper 24, i.e. back and forth on a sled moved.
  • FIG. 5 is another variant of a foreign matter removing agent in the form of a telescopic suction tube 41 shown.
  • This suction pipe 41 consists of three hollow cylindrical Pipes 42a, 42b and 42c, the diameter the first is larger than the next Tube.
  • the upper edge of the middle tube 42b is after flanged on the outside and the inner edge of the upper tube 42a is crimped inwards so that the protruding annulus 43 of the middle tube 42b and the one projecting inwards Annulus 44 of the upper tube 42a a small hollow cylindrical Leave space that increases or decreases depending on how far the middle tube 42b in the upper tube 42a is inserted.
  • It is similar lower tube 42c is formed with respect to the middle tube 42b and therefore need not be described further.
  • the upper side of the upper tube 42a is one Cover 45 completed, in which a central circular hole 46 is provided, which is completed with a coarse sieve 47 is.
  • a Small hole 48 is provided, which with a hose 49 a pressure source, which is represented by an arrow P, connected is. If this hole 48 is now pressurized with compressed air the hollow cylindrical space between the Pipes 42a and 42b enlarged so that the pipe 42b after is moved up. This continues until the pipe 42b on the Stop ring 50 is present at the lower end of the tube 42b. Then there is another hole 51 in the lower side of the tube 42b in connection with the hole 48, so that now also the pipe 42c can be pulled up by the compressed air.
  • the suction pipe 41 is with a flexible hose 52 on a suction (negative pressure) connected in the manner of a vacuum cleaner.
  • a U-shaped track 53 is schematic shown, on the left a carriage 26 for the Gripper 24, the suction means 35 or the suction pipe 41 (FIG. 3 to Fig. 5) and on the right another carriage 54 for the Foreign body detection unit 7 (Fig. 1) are shown.
  • the reciprocation of the sled 26 and 54 over the Total width of a bale of the bale width is with double arrows 55 specified.
  • the running rail 53 itself is below of the two arms 5 and 6 (Fig. 1) in a conventional manner hung (not shown), and so circles the - here dashed lines - support arm 3 of the removal arm.
  • the Running rail 53 therefore extends at both ends to the rear of the tower 2 so that the slide 26 drive to the waste containers 25 ', 25' 'on the side can to get there - similar to that described with reference to FIG. 2 - to deposit the removed foreign objects.
  • Fig. 6b the state is indicated when the two carriages 26 and 54 their reciprocation on the same side of the support arm 3 (or the removal member). It understands that the carriage 26 shown in Fig. 6a If the waste container 25 'starts and in Fig. 6b case shown the waste container 25 ''.
  • the carriage 26 with the gripper 24 is on the left the track 53 is shown schematically and simultaneously on the right the carriage 54 for the foreign body detection unit 7 on the track 53.
  • the carriage 26 or 54 is each with two driven rollers 56 and with two free running rollers 57 suspended on the track 53.
  • For Supply energy of the motors and for the transmission of the Control signals for the driven rollers 56 and for the Gripper 24 has a pickup 58 with contact loops 59, which made sliding contact with on the track 53 strips 60 on the side for energy consumption produce.
  • Corresponding contact loops 59 are provided on the pickup 58 for the carriage 54, which the required Supply energy and control signals from on the strips 61 attached to the other side of the running rail 53 record, tape.
  • FIG. 7a is the top view according to the arrows C-C in Fig. 7 is shown schematically.
  • the ablation member 4 both in the can remove one direction as well as the other and at the same time the function of foreign body detection and the removal of foreign bodies as described above are carried out in both directions. If the bale removal machine 1 is now in Fig. 6a moved to the right (see arrow), there is a possible move to the Bale surface foreign objects from the back and forth foreign body detection unit 7 detected, and due to the driving speed of the bale removal machine 1 determines when the removal member 4 reach this foreign body would.
  • the support arm 3 is raised and lowered again after this point so that this part of the Fiber bale is specifically overlooked or “skipped”.
  • the sled 26 is the foreign body removal has been moved into the correct position so that the gripper 24 (or also the suction means 35 or the suction pipe 41 - FIG. 3 to 5) can remove the foreign body.
  • the bale removal machine 1 moved back so far that the also released "stripes" (non-worn layer) is removed, or the bale removal machine 1 runs just keep going and capture this "streak” at the same time with the next removal process (on the return trip). If the removal of the foreign body unsuccessful for the first time a second attempt is started.
  • the bale removal machine 1 after a predetermined Number of unsuccessful attempts switched off and the Operating personnel a warning signal (flashing light or the like) given.
  • the carriage 26 are for the Foreign body removal (gripper 24, suction means 35 or suction pipe 41) and the slide 54 for foreign body detection provided on the same side of the day arm 3.
  • the carriage 26 is in an outside of the Waiting position and moves the Carriage 54 back and forth in a certain cycle. If one Foreign material is detected, the bale removal machine 1 , it drives back a certain distance and becomes the foreign body is removed from the gripper 24. After successful Distance then the bale removal machine 1 runs again normal continues, taking a period of time slow start can be provided so that the Foreign body detection immediately after the located foreign body is fully operational again.
  • Such processes are a matter of course through a program - not described in detail here recorded in the computer 21.
