Definitions

  • the invention relates to a method according to The preamble of claim 1 and a device according to The preamble of claim 3 and a punching device with such a device.
  • Such feed systems serve the supply of sheet material, e.g. Sheets of steel or aluminum sheet, to a punch press, which corresponds to the tables punching out blanks, e.g. round lids for cans.
  • sheet material e.g. Sheets of steel or aluminum sheet
  • punch press which corresponds to the tables punching out blanks, e.g. round lids for cans.
  • DE-C-43 09 949 and DE-C-43 45 184 is a genre Feed system for a punch press with a double row Tool known in which the feed with two Feed devices takes place, one another in the Hand over the punching press.
  • the first feed device has two grippers, which in the Space between two sliding surfaces arranged for the panels are and arranged below the sliding surfaces Actuating means are actuated. One side of the one Sliding surface arranged adjustment ensures the Feed movement.
  • the second feed device has a slide movable above the sliding surfaces, the arms with tongs carries. The sled is going through moves another feed drive.
  • DE-C 41 35 901 shows a feed system a feed device and a feed carriage, wherein between these a handover of each panel takes place at the first punching step. It is doing a single-row Punching tool shown, so in addition to that a shift of the panel in the direction perpendicular to the feed direction Direction is done to dense as much as possible to achieve the blackboard.
  • Another feed system is shown in DE-C 34 37 642.
  • the invention is based on the object Method for advancing sheets or a feed device to create that as easy as possible various sheet metal formats can be converted and the feed also allows very narrow metal sheets.
  • both feed devices above the plane supporting the sheet metal usually the the feed level forming table are arranged is an adjustment of these feed devices for adaptation to the metal sheet width possible without the appropriate Recesses in the plane or in the table necessary are that worsen the flat pad of the sheet metal.
  • the invention is also based on the object to provide a feed device, the one simple conversion to different board formats allows and can also advance very narrow boards.
  • FIGS. 1 to 3 show schematically in FIG Top view and side view of the feed device 1, which is arranged in front of a punching device 2, the a tool 4, which consists of a metal sheet.
  • 3 Punching out objects 5 (punched holes are shown by way of example), so that after punching this Items are present in isolation and from the sheet metal 3 only a skeleton remains.
  • the way of Punching is here, as known, not further explained. It can in a known manner a punching with a double row Tool take place, so that the respective sheet metal only in the feed direction A by the punching device.
  • the feed device 1 preferably has a support and guide member 6, on which Carriage 7 and 12 in the feed direction and in the opposite direction are movably arranged.
  • the sled will be by a drive 17, not shown in the feed direction and moved in the opposite direction, e.g. by Timing belts or chains around rollers 18, 19 in the support member 6 circulate, and to which the carriages are attached.
  • the drive for the carriages are controlled by a controller 25, which also signals from position sensors 26 for the sheet can receive and which continue with the controller 27 for the punching device 2 is in communication with the feed and to synchronize the punching.
  • the control 25, the location of the carriage can also be through sensors or by encoder on the drive 17 recognize.
  • the feed device 1 operates on known manner such that the first feed device 7-10 a stacked from a stack, not shown Sheet 3, which is placed on the feed table 20 becomes, and takes in the direction of the punching device advances.
  • a second feed device 12-15 is at the same time busy, a previous one Lead sheet through the punching device 2, this in a known manner in synchronization with the punching movement he follows.
  • a transfer position which in FIG 2, one of the first feed device is shown 7-10 inserted into the punching device 2 Sheet transferred to the second feed device 12-15.
  • This handover may e.g. and as shown in FIG of the first punching, but of course, too take place later after a few punching operations.
  • the Transfer takes place in that the gripping means 10 of the first Feed device and the gripping means 15 of the second Feed device reach the same feed height, so that the gripping means 15 can grip the sheet, which was previously held by the gripping means 10, these release the sheet.
  • the gripping means 10 and 15 have known per se pincer-like components, which open and Close can be pressed to the respective sheet metal let go or grab.
  • the gripping means 10 and 15 also have in the conveying direction facing backwards Fortsuits 9 and 14 on which the tongs with management and actuation elements 8 and 13 on the Connect carriage 7 or 12 respectively.
  • the guiding and actuating elements 8, 13 are slidable on the carriage 7 and 12 respectively attached so that their location along the respective Sled can be adjusted.
  • About the Fort accounts 9 and 14 can also be the operation of the forceps opening and closure.
  • the guide elements 8 and 13 are on the carriage transversely to the feed direction A adjustable, with their mutual distance is shown in Figure 2 with B and B1.
  • the Adjustment along the carriage 7 and 12 takes place for Adaptation to the respective sheet metal format.
  • the first feed device 7-10 designed so that in the transfer position only the gripping means 9, 10 through the second feed device 12-15 pass through while the guiding and actuating means 8 and the carriage 7 of the first feed device seen in the feed direction behind the second Feed device 12-15 remains.
  • This allows one easy adjustment of the distance B of the gripping means 9, 10 of the first feed device independent of the second feed device and also easy setting the distance B1 between the gripping means 15 of the second feed device.
  • the setting of these distances B, B1 is further simplified by the fact that both Feed devices above the table 20 and the Feed level are arranged. This gives good accessibility for adjustment or conversion and further an independence from breakthroughs in the table 20, like her at from below to the sheet attacking feeders needed.
  • the support member 6 can by fastening means not shown above the same or laterally attached to the machine frame be.
