Definitions

  • Sheet metal printing machines and sheet metal painting machines are used for printing or painting of metal panels, from which after the Printing and / or painting cans for packaging purposes, Lids for these cans or for jars, closures for bottles or similar made of thin sheet Articles are made. Since the metal sheets in general, they must be printed in multiple colors the press within very tight tolerances be fed to a longitudinal offset and / or transverse direction of the individual paint orders avoid. Since a single sheet of metal is usually several Cuts for the intended sheet metal articles includes and at least two within one cut narrow area strips in the area of a later solder or weld seam remain free of paint and varnish the paint application must be positioned very precisely become.
  • a feeder arranged. It has two stops, one in one certain mutual distance on the first drum the machine in question are arranged and with this circulate. This will be the first machine drum the metal sheets are fed by means of a feed device, for example by a belt conveyor is formed. Because this feeder is an accurate Place on the stops of the machine drum is not guaranteed as another part of the berthing facility a pressing device available, which are parallel to the path of movement of the sheet metal relative is movably guided to the attacks and by means of a power drive towards the stops and being driven away from them. Here is the drive speed the pressing device larger than the escape speed of the stops on the machine drum.
  • the pressure device has in conventional Application devices two pressure members on the form-fitting on the rear edge of the supplied sheet metal put on and slide the metal sheet in front of you - and finally against the stops on the machine drum to press. These pressure members are by means of a flexible power transmission member connected to the pressure device so that the metal sheets always with the same pressure on the stops be pressed independently of the Force of the drive of the pressing device is. generalizing you can put on the pressure members on the metal sheet also referred to as coupling and the pressing members themselves accordingly as coupling members describe.
  • the sheets made of sheet steel or light metal sheet are manufactured with ever smaller wall thicknesses and processed into sheet metal articles.
  • the coupling link also transversely movable to the path of movement of the metal sheets is guided, the metal sheets can be created be aligned sideways at the same time.
  • this also does not apply to the secondary alignment element Adjust to the side edge of the Metal sheets if their width changes.
  • an application device 10 can be seen in a partially simplified form, which serves a sheet 11 of generally rectangular cut with the front edge 12 at two stops 13 of a sheet metal printing machine or a sheet metal painting machine. These stops 13 are on a drum of the relevant Machine arranged and run with this around.
  • the metal sheet 11 is not shown by one Feed device on a flat movement path fed and by means of the application device 10 to the Attacks 13 created. Here is the speed of approach the sheet 11 larger than the escape speed of the attacks 13.

  • the pressing device 14 is by means of a not shown guide parallel to the trajectory the metal sheet 11 is movably guided. She will be in Direction towards the stops 13 and away from them moved by a drive 21 which is shown in FIGS. 1 and 2 symbolically indicated only by a double arrow is.
  • the pressing device 14 has for coupling on the metal plate 11 two coupling links, both of them are designed as a suction cup 22 and 23. Instead of of the suction cups can also be the coupling links are formed by electromagnets.
  • Each of the suction cups 22 and 23 has one Lifting device 24, advantageously in the form of a pneumatic piston drive, both connected are arranged on a common carrier 25.
  • This carrier 25 is on a guide 26 of the pressing device 14 parallel to the path of movement of the sheet 11 movably guided, which in Fig. 1 by the double arrow 27 is illustrated.
  • two coil springs 28 and 29 act as a resilient power transmission member, through that after creating the leading edge 12 of the sheet 11 at the stops 13 a certain adjustable pressing force on the sheet 11 is exercised.
  • the pressing device 14 is otherwise trained and arranged that when coupling to the sheet 11 their coupling members 22 and 23 so as far as possible in the vicinity of the leading edge 12 of the sheet 11 and thus also in the neighborhood the connecting line of the stops 13 located are.
  • the primary alignment member 16 is with a positioning device 31 connected.
  • the positioning device 31 has two mutually interacting stop parts 32 and 33 on. One is a stop part 32 rigidly connected to the alignment member 16. The other Stop part 33 is relative to the path of movement Sheet 11 adjustable to a predetermined distance educated.
  • the positioning device 31 also has a double-acting power drive 34 with two specific end positions. He's about one resilient power transmission member 35 with the alignment member 16 connected.
  • the drive pulls 34 the alignment member 16 in a standby position back in which the alignment member 16 is outside the path of movement of the sheet 11 is so this the feed device 10 fed freely can be.
  • the power drive 34 via the power transmission link 35 the alignment member 16 in the direction of the path of movement the metal plate 11 until the two stop parts 32 and 33 meet. That’s it Alignment member 16 positioned in its operating position, in which it is exactly at the target position of the left margin 18 of the sheet 11 is located. Unless the metal sheet 11 of the application device 10 on a movement path was supplied, the beyond the target point closer is located at the positioning device 31, the Sheet 11 from the alignment member 16 to the desired point laterally moved as soon as the drive 34 switched on becomes.
  • the secondary alignment member 17 is also connected to a positioning device 36. It is the alignment member 17 also by means of a not shown Guidance in the direction of movement of the sheet 11 immovable and guided transversely to it.
  • the positioning device 36 has a double-acting Power drive 37 with two specific end positions on. It is via a resilient power transmission link 38 connected to the alignment member 17.
  • the Positioning device 36 points for alignment member 17 no stop parts.
  • the power drive 37 is, however within the positioning device 36 to some extent Area towards the trajectory of the Metal plate 11 adjustable to and away from this, so that the power transmission member 38 to a certain Pressing force can be adjusted with the it to a located in the application device 10 Sheet 11 acts. This force of the power transmission member In any case, 38 is less than the force of the power transmission member 35 of the positioning device 31st
  • the drive pulls 37 the alignment member 17 in a standby position back in the outside of the trajectory the sheet 11 is located.
  • the drive pushes the alignment member 17 in its operating position, in which it is on the right side edge 19 of those located in the application device Sheet 11 is present. If the sheet 11 of the feeder 10 fed on a trajectory with its right side edge 19 beyond the Desired point closer to the positioning device 36 is, the sheet 11 is laterally by the alignment member 17 moved until their left outer edge 18 on the Alignment member 16 in its operating position is applied.
  • the primary alignment member 41 and its positioning device 42 is the same as the alignment member 16 and the positioning device 31 (Fig. 2) formed and arranged.
  • the serve as secondary alignment member 43 Coupling members of the pressing device 14, as soon as the coupling members 22 and 23 on the metal sheet 11 are coupled.
  • These coupling links in the form of Suction cups 22 and 23 are each via a lifting device connected to the carrier 25.
  • the guide 26 of the carrier is also used as an alignment member 25 designed so that they have a relative movement of the Carrier 25 not only compared to the pressing device parallel to the path of movement of the sheet 11 but also allows across.
  • This secondary alignment member 43 is with the Positioning device 44 connected, largely the same as the positioning device 36 (FIG. 2) is.
  • the positioning device 44 is by means of a bracket 45 rigidly connected to the pressing device 14, so that they their relative movement when pressing the Sheet 11 to the stops 13 in both directions participates.
  • the positioning device 44 is the drive 46 and the resilient power transmission member 47 so arranged and designed that in an operating state of the drive 46, the alignment member 43 from his Rest a certain amount to the side of that primary alignment member 41 is pulled away and that it in the other operating state of the drive 46, in the absence a metal sheet 11, by about the same amount beyond its resting position towards the primary Alignment member 41 is shifted. This will made sure that one might be opposite theirs Target position, sheet metal sheet shifted to the right 11 against that in its operating position primary alignment member 41 is moved. At a Sheet metal 11 fed to the left catches this secondary alignment member 43 with its positioning device 44 the lateral displacement movement of the Sheet 11 on by the primary alignment member 41 and its positioning device 42 is triggered.
