  • the packaging machine 2 is a station for applying glue coats in the exemplary embodiment on cardboard packaging.
  • the principle of operation of the exemplary embodiment explained in more detail can, however, also be applied to the regulation of others without difficulty electronic switching processes for motors, conveyors, sealing jaws and others Transfer packaging machine components.
  • the packaging machine 2 has a conveyor element 4 on which to be packaged Cardboard boxes are moved.
  • the conveyor element 4 consists of drive rollers 6, around which an endlessly revolving conveyor belt 8 is wound.
  • One of the conveyor rollers 6 is driven by a motor 10.
  • the speed of the conveyor belt 8 is monitored by a sensor 12.
  • the sensor 12 is via a connecting line connected to the processor 14 of a control device 16.
  • the motor 10 and a light barrier unit 18 are connected to the processor 14.
  • the light barrier unit 18 can be used as a sensor to determine whether cardboard boxes as moving elements in the packaging machine 2 actually from the conveying element 4 can be moved. Via a light barrier unit 18, for example the moving elements reach a certain position, a speed of movement, a spatial location or other relevant parameters be queried.
  • Light barrier unit 18 can be used. Via the connecting cable the operational parameters of the engine 10, the sensor 12 and the Light barrier unit 18 transmitted to the processor 14. Through the sensor data, which the processor 14 receives from the connected sensors is the Processor 14 by means of correspondingly programmed processing software able to send a control signal to an electronic one from the sensor data obtained Output cam switch 20.
  • the electronic cam switch 20 must can no longer be mechanically contained in the packaging machine 2, but can be electronically simulated by the evaluation software. Physically, that's electronic Cam switching mechanism 20 then only as an output plug of the control device 16 available.
  • the control signal output by the electronic cam switch 20 is sent to a Actuator transmits a nozzle motor or a valve 22 in the exemplary embodiment through which a portion of glue is ejected from the glue dispenser 24.
  • a nozzle motor 22 can be of the electronic cam switch 20 in general also hydraulic or pneumatic valves, servomotors, electric Switches and the like can be controlled.
  • the Cover a trajectory with glue from the outlet nozzle to the surface of the box.
  • the electronic cam switch must be able to hit exactly at the desired point 20 issue the actuating command earlier by the time interval that the trajectory corresponds to the portion of glue.
  • dead and reaction times of the actuated actuators and others factors influencing the time when determining the right time for the output of an actuating signal.
  • the function and dead time or reaction time add up to the total delay time. Calculate such delay times individually for each switching function, also depending on the dimensions and special features of a specific packaging unit, which the Packaging machine 2 passes. For reasons of simplification, the delay time designated T in the exemplary embodiment.
  • the starting position 26 means exactly the position that a box has on its conveying path must have reached, at the same time the control signal to the nozzle motor 22nd is transmitted to the portion of glue taking into account the delay time T. to be able to hit the box in the right place.
  • the target position 28 is the exact position of the carton that the carton is on its path must have reached where the portion of glue dispensed at the correct one Spot hitting the box. From the starting position 26 to the target position 28 the Carton as an element moving in the packaging machine the distance sT back. The distance sT is shown in Fig. 1.
  • the time interval of the delay time tT required that for the serving portion Glue and the transported box is the same.
  • the one to be covered by the portion of glue Path in the exemplary embodiment is shorter than the distance sT that of the transported carton is to be returned.
  • these ratios can vary vary depending on the application.
  • the on the processor 14 active evaluation software must be designed so that it functions the delay time tT for the carton being transported and on the other hand based on the Conveying speed of the conveying element 4 determine the reaction distance sT can.
  • the on the processor 14 active evaluation software In order to achieve an appropriate at variable conveying speeds of a conveying element 4 Provide a forecast of the funding period in the upcoming forecast period To be able to, it is no longer enough to feed at constant conveyor speeds expected.
  • a memory element 30 that is connected to the processor 14 and can be part of the control device 16, data must be stored be through which the dynamic speed behavior of the conveying element 4th is described.
  • the data can be in the memory element 30, for example, in the form of stored path curve tables, mathematical functions, vectors and / or as further describing the dynamic movement processes of the elements Data stored.
  • the processor 14 accesses that on the memory element 30 stored data and processes them into a switching signal for electronic cam switch 20, which is issued to this in time or that contains an instruction for timely switching. That way ensure that the portion of glue to be applied to the box is exactly the right one the programmed position P hits the box, although the motor 10 is a servo motor is operated at a variable speed. It will work safely achieved if for the regulation of the working speed of the engine 10 in one Packaging process and for determining the delay time on the same in the Storage element 30 stored data is used.
  • Control software for the packaging machine 2 for example for "learning” new packaging
  • the care of the Control software for the packaging machine 2 is simplified and the operation more reliable when in the Control software doesn't have different locations for speed data ever are programmed according to the control purpose, but only a single storage location.
  • Exchange of speed profiles or when "learning" new packaging it is sufficient to change or add to the data in just one place.
  • FIG. 2 the time t is plotted on the X axis and the speed on the Y axis v.
  • the constant speed according to the state of the art A functional element in the packaging machine 2 is represented by the line 32.
  • An entered cam switching position is in the control for one point in time I programmed.
  • the Shift position in the way back by the amount tT to shift position II become.
  • the shift of a switching position of a cam can be arbitrary over the work area 34.
  • the switching position is advanced doing so in the direction of arrow 36, a relocation in the direction of arrow 38.
  • Die Fig. 2 shows the situation with regard to a switch-on position for a cam you can define a switch-off position in the same way.
  • the situation shown in FIG. 3 is different at variable speeds
  • the variable speed is represented by line 40.
  • positions I and II in the exemplary embodiment are acceleration and a reduction in conveying speed. Taking this speed profile into account places a carton conveyed by the conveying element 4 in the time interval tT a longer distance back than with the speed assumption shown in FIG. 2. Because of the higher conveying speed, the switching position would have to change a smaller amount is advanced, for example to position IIa.
  • the processor 14 needs the Storage element 30 stored data on the expected speed profile.
  • the data stored on the storage element 30 can be processed by the processor 14 in Time forecast data can be converted. If the sensors signal a change the target state of drive data, can either automatically or on Command the times for switching the cam switch mechanism to be redetermined or the stored data to describe the speed behavior will be corrected. Such a correction function is useful if the speed behavior of elements changed due to wear, for example.
