Definitions

  • the invention relates to a method for setting glue points on objects that are cyclically or at a discontinuous speed according to a defined motion law by means of a valve-actuated gluing system having glue nozzles, the specific system-related inertia of which is caused by the effective switching times t w (switch-on and switch-off times) of each valve correcting lead time or pilot control time t 1 is compensated for.
  • the invention also relates to an arrangement for setting glue points on objects transported in cycles or at a discontinuous speed by means of a valve-actuated gluing system having glue nozzles, which, with a control of the glue supply and thereby the system-related inertia of the gluing system by advancing (retention time t 1 ) of switching times t w compensating control arrangement is provided.
  • nozzle gluing or gluing systems of the type mentioned at the outset are also increasingly being used in the tobacco industry, with ever increasing demands being placed on such systems as a result of increased machine outputs. It has hitherto been customary to compensate for the system-specific inertia of such a system, from the energization of the valve via the movement of the nozzle needle inside the valve to the final glue flow, by means of a corresponding pilot control. Specific characteristic values assigned to each valve are taken into account, which in total define the inertia of the glue application depending on the boundary conditions, such as the type of glue, pressure, temperature, etc. In this way, precisely positioned glue beads are produced at constant speed conditions.
  • the invention has for its object, even under difficult conditions, where during the time the glue valve is electrically started up to final flow of the glue or the electrical switching off of the glue valve until the glue bead finally tears off, the speed changes Position the glue beads exactly.
  • a correction value t G is derived from the law of motion of the transported objects in the respective gluing phase (switch-on or switch-off phase), which is included in the system control of the gluing system which determines the lead time or pilot control time t 1 .
  • t w t 1 + t G customized.
  • the speed and the position of the conveying means transporting the objects are preferably monitored.
  • control arrangement is provided with control elements which accelerate or decelerate the objects during the on or off time of a valve and from this obtain a correction value t G for adapting the lead time t 1 .
  • the advantage achieved with the invention is that the lead time assigned directly to the start and end points of the gluing z. B. even with clockwise or swelling moving objects on which several glue beads are to be generated in particular within a movement cycle, an exact positioning of the glue beads is guaranteed.
  • Such a glue bead-specific compensation results in a further advantage in that, even with indirect position determination of the objects by means of machine-related incremental encoders, machine-dependent position errors of the objects are included in the lead time of the start and end points of the glue bead.
  • the inertia-related lead times only need due to the specific position-dependent Lead times to be supplemented by a high positioning accuracy to maintain, which ensures quick interchangeability of the valves.
  • Pack blanks 1 in the form of so-called blanks are moved in a clockwise manner in the direction of arrow 2 along a transport path 3 by a conveyor in the form of a conveyor belt 5 in accordance with FIG.
  • the pack blanks 1 are to be provided with one or more glue points 8 one behind the other in the conveying direction 2 during their conveying cycle on their different surface sections 4, 6, 7.
  • the transport path 3 is assigned a gluing arrangement 9, comprising a glue container 11, a conveying unit 12, a pressure regulator 13 and a valve 14 with a contact nozzle 16 for individual or a row of glue points 8 located one behind the other on the different surface sections 4 or 6 or 7 of the pack blanks 1.
  • a control arrangement 17 linked to the gluing arrangement 9 is used to control the respective valve 14 at all speeds of the machine System-related mechanical or electrical inertia of the glue application system is compensated for by a pilot control or lead time t 1 assigned to each individual valve, ie by shifting the switching positions E 1 and E 2 forward when switching on or switching off the valve 14 according to FIG. 2.
  • the lead time is no longer assigned to the valve but to the start and end points of the gluing (glue bead-specific compensation) such that the effective lead times t w of each input are determined by means of the correction value t G defined by the sign and the magnitude of the speed change. or switch-off phase of the gluing system during the acceleration of the pack cut 1 by reducing the lead time t 1 by the correction value t G and during the delay of the pack cut by increasing the lead time t 1 by the correction value t G.
  • Another advantage results from the fact that in a clocked or swelling running material flow a high positioning accuracy is achieved when using more than one glue bead is applied to a valve within one cycle should.
