Definitions

  • the invention relates to a device for cutting stacked, leafy crop, with a table to hold the Good, a knife for cutting the good, one on the good lowerable press beam and a motor driven feed saddle to move the goods in the direction of the knife, and with an electronic display device for displaying the position of the feed saddle in a display field and with an electronic correction device for correcting the Position of the feed saddle, the correction device a rotary pulse generator which can be actuated manually by means of an actuator with switch and an evaluation unit controlled by them which controls the drive of the feed saddle, wherein, in a first position of the switch, the rotary pulse generator is activated and a different directional Deflection of the actuator a different directional travel speed of the feed saddle conditionally, and in a second switch position of the switch Rotary encoder is deactivated.
  • Such a device is known from practice. With her finds a so-called electronic handwheel to correct the Position of the feed saddle use. Must be corrected the feed dimension in all cases in which the feed saddle, be it due to automatic or manual Actuation of the drive of the feed saddle, not its exact one Has reached position. The device is in automatic mode usually make less correction than in manual operation, where the specifications by the operator done directly.
  • the feed saddle comes Task to advance the material to be cut. Has out for whatever reason, the feed saddle is the one to be cut Advance well too far, thus over its cutting position there is no possibility of cutting the good at Retract the feed saddle with, but this is to be done by the operator of the goods pushes against the retracted feed saddle or the goods presses against the feed saddle when moving it back.
  • the known electronic handwheel has the disadvantage in that the operator does not know exactly at what speed the feed saddle is moved forward or backward because due to the electronic coupling of the one he takes Actuator via the rotary encoder with switch no mechanical Connection to the drive of the feed saddle is made. So the operator activates when pressing in the control element or Handwheel the switch, with which the evaluation unit the starting position of the actuator, and it represents the then made Deflection of the control element, thus the angular momentum encoder, a Reference variable for the respective direction-related travel speed of the feed saddle. The operator turns it Control by one detent, the encoder generates an increment, which is recorded by a counter module.
  • the evaluation unit reads the result with software and controls, taking into account the direction of rotation of the encoder, the drive of the feed saddle, for example with the speed, represented by the reference variable +1.
  • This The reference value corresponds to a very low travel speed of the feed saddle in the direction of the cutting knife.
  • a deflection on the actuator in the opposite Direction for example to the value -3, this would a travel speed three times the value 1, however in another direction, away from the knife.
  • the object of the invention is the operator of the cutting device moving to the correction position of the feed saddle despite electronic decoupling of the actuator from the drive of the To facilitate feed saddle.
  • the task is solved with a device of the beginning mentioned type in that when correcting the position of the Feed saddle the travel speed of the feed saddle in the display field directly or indirectly, as well as directional is visually reproduced.
  • the operator can See the display field at what speed and at what speed Direction of the feed saddle moves.
  • the Display field shows the position of the feed saddle, see above that it is easily possible for him to estimate whether he is because of a relatively large difference between target and actual position of the feed saddle with a relatively high travel speed Correction can bring, or whether it only with relative lower travel speed is possible because the actual value of the feed saddle differs only slightly from the setpoint.
  • the software is preferably designed to be in the state automatic travel, large travel speed levels, For example, those that have three levels in each direction of travel go out, not implemented, but a maximum of three levels of eight possible in manual operation, for example.
  • Figure 1 illustrates the basic structure of the cutting machine 1 for cutting, not shown, stacked, leafy crop seen from the operator side.
  • the cutting machine 1 has a stand 2 with an upper portal frame 3, also a table 4, the table surface 4a perpendicular to Leaf level extends.
  • a lowering and liftable knife 5 mounted behind which one in this view press bar not visible also lift in the portal frame 3 and is lowerable.
  • the knife 5 and the portal frame are movable in planes parallel to the sheet plane.
  • a feed saddle 6 is provided, the serves to advance the material to be cut.
  • the operator facing side of the feed saddle 6 runs parallel to Cutting plane of the knife 5; the feed saddle 6 is vertical to the leaf level of the present Figure 1 in the area of the rear Table part 29 can be moved back and forth.
  • two light barrier grating 8 are arranged the knife area of the cutting machine against unauthorized handling secure in this area. Is above the cutting knife 5 on the operator side of the portal frame 3 with a control panel 9 Enter and control buttons 10, a display panel 11 and one electronic handwheel 12 arranged.
  • table 4 has two cut-off buttons 13, a foot lever 14 for the cut hint.
  • FIG. 2 illustrates this in a schematic representation Operating principle of those used in the cutting device Correction device.
  • the control panel 9 is illustrated at the top right, its circled area closer to the left is made clear.
  • the electronic Handwheel 12 is used for fine adjustment of the feed saddle 6 in the tenth and hundredths of a millimeter range.
  • the Electronic switch 20 is used to detect the starting position of the electronic handwheel. With the switch 20 assigned Double arrow is the mechanical direction of movement of the Switch 20 indicated to open or close it.
  • the setpoint is specified via the incremental rotary pulse generator 21 due to the direction of movement of the handwheel.
  • the Dash-dotted line in the illustration shows that the Rotating the handwheel 12 visually detects the hand encoder position is possible in the display field 11, the actual position of the feed saddle 6 by an actual value display 30 is shown, in the present case the saddle position value 111.111 cm.
  • the electronic switch 20 and the incremental Rotary pulse generators 21 communicate with the evaluation unit 23.
  • An essential part of the computer system 23 are a CPU computer card 24, a counter pulse card 25 and the table motor control management shown with setpoint output 26.
  • the motor 31 stored in the table 4 is output via the setpoint output controlled, the drive spindle 27 via a gear 32 of the feed saddle 6 drives.
  • the range of motion of the Feed saddle 6 is marked with double arrows.
  • the Position of the spindle 27 and thus also the actual value of the feed saddle 6 is detected by means of a detection element 28, both with the counter pulse card 25 and with the Table motor control management 26 communicates. It takes place like this position monitoring of the rotary pulse generator 21 of the feed saddle 6 instead of, while simultaneously recording the target and Actual values of the feed saddle.
  • the feed saddle 6 returns at a defined speed, for example at a speed of 4 cm / sec. Does the operator deflect the rotary knob 15 so far that point 16 reaches the scale value 8, there is a correspondingly larger Feed speed of the feed saddle 6. If the pressed Turn knob 15 to the right that point 16 passes right over the rectangular marking 17, the feed saddle 6 moves with one of the marked ones Position corresponding speed forward, i.e. in Direction of the cutting knife.
  • the actual value display 30 shows the current position of the feed saddle, white the operator can see how far he is from the target dimension readily estimate whether it is higher or lower Feed speed approach the nominal size of the feed saddle can. If the operator leaves, for example, in FIG shown position of the rotary knob 15 and thus the rotary encoder - Position 4.5 - release the knob 15, the switch switched off, and the counter module of the rotary pulse encoder 21 zeros, so that this recognizing evaluation unit 23 Feed movement of the feed saddle 6 interrupts. Will be later the knob 15 pressed in this position shows the display 18 the point 16 as a reference variable for the feed rate of the feed saddle in register with the rectangular one Mark 17. Only when turning the rotary knob 15, the Point 16 in the sense of the increments generated by the Counter module are detected, to the right or left.
  • Figure 4 shows that the automatic operation of the cutting machine Numbers 4 - 8 of the display 18 are not shown and in the rest of the evaluation unit 23 is programmed so that, too when the rotary knob 15 in the sense of the embodiment according to 2 is deflected to the maximum, only one feed rate of plus or minus three units is possible.
  • the feed saddle is thus fed at a lower rate Speed towards and from the cutting knife path. The purpose is to see large deviations within short time from the automatically set feed saddle position to exclude.
