Definitions

  • the invention relates to a method for starting up or retrofitting a sheet metal processing machine according to the preamble of claim 1 and a modular magazine for carrying out the method according to claim 4.
  • Sheet stacking magazines and sheet separating devices are known and are used in many sheet metal processing machines and are also used, for example, in conventional can making machines, where the highest demands are placed on the separating mechanism: in medium-output machines up to 500 and in high-performance machines up to 1000 sheets per minute.
  • the adjustable stack supports of the sheet stacking magazine are designed, for example, as four angle profiles which are assigned to the sheet stacking corners and which each have to be coordinated with one another when the format is changed. In order to enable the stacking of individual sheets in the cadence mentioned, it is also known to help with the supply of separating or spreading air that the individual sheet is properly separated from the sheet stack.
  • the bottom sheet separating catches In order to keep the deflection of the bottom sheet, which is picked up and transported by the separating device, to the necessary and precisely defined dimension, the bottom sheet separating catches must be positioned exactly; A different positioning must be selected for each sheet format, sheet type and each sheet coating. Both the adjustable spreading air elements required for this and the stack supports for guiding and holding the stack of sheets are machine-bound, that is to say arranged in the vicinity of the magazine on the machine itself.
  • the setting parameters mentioned also include a different, but then constant, distance from the bottom sheet to the separating element, depending on the sheet to be separated.
  • the present invention has for its object to propose a method for commissioning or retrofitting a frame welding machine, which allows a production commissioning or changeover to another product (sheet format and / or sheet material change) in a shorter time and simply, i.e. without the involvement of a specialist, who can be carried out by line personnel.
  • this object is achieved by the features specified in the characterizing part of claim 1; a magazine for performing the method has the features of claim 4.
  • auxiliary elements for the separation are no longer installed in the machine itself, but on the frame of a modular magazine, the settings can be saved by removing the magazine.
  • This in turn allows a modular magazine with the help of sample or sample sheets e.g. on a test bench of the manufacturer or at another location where specialists are available (e.g. at a central location of the line operator).
  • the operational magazine can then be easily mounted on the machine, so that the changeover time (or time for commissioning) is minimized and the need for specialists on site is eliminated.
  • a sheet stacking magazine 1 is shown in the unfilled state, for example for a can manufacturing machine.
  • the sheet stacking magazine 1 has a frame 4, which is positioned by means of adjusting screws 5 (on a welding machine of a known type, not shown to relieve the figure, see e.g. CH-A 671 945).
  • the welding machine has a separating device e.g. according to EP 0 575 707 A1 or EP 0 406 608 B1, which is also not shown.
  • the sheet separating device grips, in a manner known per se, the bottom sheet of a sheet stack (not shown) filled into sheet stack magazine 1 from above, for example sucked it in, and then transports it in the direction of arrow P according to FIG. 1 to a further processing station.
  • a plurality of stack supports 6 and 18 are arranged on the frame 4 for guiding and holding the stack of sheets.
  • the front stack supports are designated 6a, the rear stack supports 6b.
  • Stack supports 18 and 6c, 6d are arranged on the sides.
  • the front stack supports 6a, the rear stack supports 6b and the side stack supports 18 are provided at the bottom with inwardly directed holding surfaces 28 which engage under the sheet stack;
  • the stack supports 6c, 6d do not have these surfaces and are only provided as stack guides, especially for the upper area of the sheet stack.
  • the holding surfaces 28 define the lower edge of the sheet stack.
  • the height of this sheet-metal stacking edge can be adjusted with respect to the sheet-metal separating device by means of the set screws 5, which determines the distance of the lowest sheet to the separating member.
  • the stack supports 6 are provided with bevels 11 at the top.
  • the distance between the front and rear stack supports 6a, 6b corresponds, for example, to a can processing size ( ⁇ ⁇ d), the distance between the side stack supports 18; 6c, 6d of the can or frame height.
  • ⁇ ⁇ d can processing size
  • the rear stack supports 6b which also form a piece, are adjustably arranged for setting the desired distance.
  • a lower part 8 of the stack supports 6b is slidably guided in corresponding recesses 9 of the frame 4 and fixed at the desired point by means of adjusting screws 10.
  • two parallel rails 14 are mutually relatively adjustable, on which the side stack guides 6c and 6d and the stack supports 18, each at the desired distance from one another, can be fixed by means of adjusting screws 15 and 19 (FIGS. 2 and 3).
  • two expansion air supply elements 22 are adjustably arranged on the profile rails 14 and can be fixed at the desired point by means of adjusting screws 23.
  • the stack supports 18 are provided in the lower region with interchangeable separating catch elements which have a plurality of groove-shaped separating catches 20.
  • Each expanding air supply element 22 is equipped in the lower area with a height-adjustable blowing nozzle 24, the blowing direction being able to be selected by means of a rotary adjustment, angular adjustment and height adjustment, preferably in three degrees of freedom, in relation to the expanding air supply element 22 and can be determined together with the desired nozzle height by adjusting screws 35.
  • the amount of spreading air can also be regulated in a manner that is not shown in detail, but in a conventional manner.
  • the distance, corresponding to the desired frame height, of the opposing elements which act laterally on the sheet metal stack is set by adjusting the profile rails 14.
  • the frame 4 is equipped with two carrying handles 30.
  • the stack of sheet metal intended for further processing must be held reliably in the sheet stacking magazine 1, but easy removal of the bottom sheet must be ensured when stacking. Especially double sheets, i.e. peeling off two sheets that stick together during the separation process must be avoided.
  • high demands are made on the accuracy of the setting of the sheet stacking magazine 1.
  • the setting accuracy is particularly important when it comes to high-performance machines that, for example, process up to 1000 pieces per minute. It is not only essential to set the stack supports 6, 18 precisely, preferably with an accuracy of 0.3 mm relative to one another, in accordance with the sheet format to be processed; the sheet separation must be additionally supported by attaching separating catches 20 and by using the separating or spreading air.
  • the adjustable stack supports 6, 18, the separating catches 28 and spreading air elements 22 and the spacing elements 5 designed as set screws are arranged on the frame 4, which can be easily removed from the stacker, and thus form a module that can be archived with the existing settings. In this way, the magazine settings found are retained when the format is temporarily changed.
  • Such a module can be available for every format intended for production. The module change can then be carried out quickly and easily by a less qualified surgeon without causing long downtimes. Even after maintenance work, for example on the stacker, which is now easily accessible due to the detachability of the frame 4, the machine can be put back into operation quickly without the lengthy magazine settings having to be made again.
  • Another advantage is that the customer can take over the machine with several intended modules without having to carry out the complicated settings himself.
  • Another advantage is that, according to the invention, it is also possible to change modules from one machine to another machine.
  • the sheet metal stacking magazine according to the invention is particularly suitable for can welding machines which work with very high cycle numbers, but are not limited to such.
