Definitions

  • the invention relates to a method and a Device for monitoring the loading of hanging wagon trains on a roving machine, the supply of tubes and Removal of coils by moving the trolley trains along a predetermined path takes place and in the event of a deviation at least one error signal is generated.
  • the starting point of the present invention is a Roughing machine with an automatic device Replace full roving bobbins with empty roving tubes, at the one containing the roving bobbins and roving sleeves Suspension trolley trains on guideways running through the wings be moved into the change position (DE 44 21 778 C2).
  • she is equipped with an assembly monitoring device, those for monitoring the presence or absence and / or for Monitoring the nature of each one in the Hanging bracket of a full wagon suspended on a trailer wagon train or empty sleeve before and / or after the change process serves.
  • the type of assembly can also be checked, So whether it is a roving sleeve or a roving spool acts. If an inadmissible deviation from the an error signal is generated.
  • the object of the present invention was a Specify method or an apparatus by means of which the Consideration of the generated error signal or the rectification of a detected mounting error can be ensured i.e. concrete procedures to correct an identified error be initiated.
  • the hanging trolley trains can from the gate of one Ring spinning machine or a waiting area (in the rear part) the roving machine in the wing area (in the front part) drive, the loading of the hanging car trains automatically is checked. If this is a missing sleeve, one is wrong equipped sleeve or a full spool detected in the hanging trolley, an error signal is generated and the operator perceivable displayed. To observe this error signal ensure it can be provided that the error signal further operations such as changing the Roving bobbins blocked against roving sleeves.
  • the hanging wagon train must be pulled back until the position recognized as faulty is the placement monitoring device has reached. This is the safest way can be achieved in that the suspension trolley pull completely out of the Wing area is moved out. But it is also possible that the assembly monitoring device the incorrectly assembled Position saves and the trolley pull only up to this Position behind the assembly monitoring device lets extend - this shortens that for the change process required time.
  • the assembly monitoring device When moving out of or the subsequent retraction the assembly monitoring device is in the wing area reactivated and the equipment of the hanging wagon train checked again. This process can repeat itself so often until no more assembly errors are recognized or until the Assembly monitoring is switched off.
  • the placement monitoring device has three sensors, which in the following as position sensor, as sleeve sensor and as Coil sensor are called.
  • position sensor can the sleeve sensor and possibly the coil sensor in the positions to be monitored are activated. He can mechanical, optical or magneto-inductive type.
  • Sleeve sensor and coil sensor, by means of which the assembly of the Positions can be recognized are preferably more optical kind, the sleeve sensor advantageous as a light barrier, the Coil sensor designed as a light sensor.
  • the assembly monitoring device also has a Control unit, which in addition to the sensors and the one Error signal identifying device and with the Drives of the suspension trolley trains and the roving machine, in particular their changing devices are connected.
  • the assembly monitoring device advantageously has also a storage unit on the misplaced positions of the Hanging trolley trains can save.
  • the position sensor can be switched by means of flags Positions of the hanging brackets assigned and on the hanging car trains are arranged, are activated to the assembly monitoring device the one for the functional Evaluation of the signals of at least the sleeve sensor to be able to provide the required information.
  • FIG. 1 and 2 show schematic top views of a Roughing machine 1. It has a waiting area 2 and a Wing area 3 on.
  • Fig. 1 there are two hanging trolley trains 4 and 5 with hanging brackets 25 in waiting area 2 on parallel tracks.
  • These two Hanging carriage trains 4 and 5 can be shown schematically Drives 7 and 7 'on tracks 30 and 30' in the respective Lanes assigned to rows of wings in wing area 3 are moved become.
  • this wing area 3 there are more Drives 7 and 7 'for moving the hanging car trains 4 and 5.
  • each track 30 or 30 ' 8 Located between the waiting area 2 and the wing area 3 there is an assembly monitoring device on each track 30 or 30 ' 8 with a position sensor 11, a sleeve sensor 12 and a coil sensor 13.
  • the position sensor 11 is over a line 18, the sleeve sensor 12 via a line 17 and the coil sensor 13 via a line 19 with a Control unit 10 connected.
  • This control unit 10 is over a line 16 with a control terminal 15 in connection.
  • FIG. 1 shows a situation in which the hanging wagon train 4 has already completely moved into the wing area 3, while the trolley 5 is partly in the wing area 3 located and positioned accordingly for troubleshooting.
  • the incorrectly equipped ones are corrected Position. Then the trailer 5 is removed from the Wing area 3 out and on the assembly monitoring device 8 retracted past again. If not misplaced position is recognized, the further Workflow of the roving machine 1, i.e. the changing process Approved.
  • the position sensor 11 is by Switching flags 20.1, 20.3, etc., which correspond to the positions, i.e. the Hanging brackets 24.1, 24.2, etc. ... of the hanging wagon train are assigned.
  • 4a shows a top view these switch flags of the hanging wagon train.
  • the dashed Indicated switching flags are displayed when the suspension wagon train is traveling effective in the opposite direction.
  • the circuit is made that when the position sensor 11 is acted upon by the front edge of the switching flag 20.1 according to line 26 in Fig. 4b the sleeve sensor 12 is not through a sleeve 25, 25.2, etc. damped, i.e. not when designed as a light barrier may be interrupted - otherwise an error signal generated.
  • the coil sensor 13 is used to determine incorrectly Roving bobbins remaining in the hanging wagon train, i.e. Forearm sleeves with winding. There - as long as hanging trolley trains with roving sleeves are equipped - at no position roving sleeves with winding may be plugged on, the coil sensor 13 is advantageous designed as a light scanner and its scanning range like this set to end in the winding of a coil. Of the Accordingly, the coil sensor does not need depending on the Position of the hanging trolley trains activated and deactivated become. It only recognizes sleeves with winding or winding remnants and triggers if this happens while driving the with roving sleeves equipped trolley, there is always an error signal.
  • Fig. 3 it can also be seen that the control unit 10 both with the sensors 11, 12 and 13 as well as via the line 16 the operator terminal 15 is connected, the control unit 10 the operator terminal 15 both acted upon and by him is applied.
  • the control unit 10 can also via further lines 16 ', 16' 'with drives of Leading machine and be functional head for. This functional loading includes in essentially locking the drives as long as one Error message is pending and after acknowledgment of the rectification in the event of incorrect assembly, the release of the hanging trolley drives only 7, 7 '.
  • the arrangement is preferred in such a way that the acknowledgment of a troubleshooting only can then take place when the suspension trolley concerned 4 or 5 is in the wing area 3 and stands there.
  • the present invention leads to a very effective one Assembly monitoring on a pre-spinning machine, in which with little effort the supply of empty sleeves 25 from the Waiting area is guaranteed in the wing area 3, wherein a possible error of the assembly point concerned can be properly assigned and corrected.
  • This one Correction of the fault in wing area 3 takes place good operator access to this point, so that overall a significant improvement in productivity and the degree of automation while maintaining a Ease of use is achieved.
