Definitions

  • the invention relates to a method for feeding flat, scaled overlapping metal sheets to at least one leading edge stop of a further processing machine, in particular a sheet metal or sheet metal painting machine.
  • From the US-A-2 257 117 shows a panel handling apparatus with a traction belt to which panels are fed from a first machine, the traction belt being operated at a substantially constant speed corresponding to the speed of the first machine, and a second traction belt separating the panels from the first Traction belt takes over and feeds a second machine, the panels rest flat on the traction belt.
  • a drive drives the second traction belt at variable speed, having a speed which is at least as great as the speed of the first traction belt when the trays are taken over by the first to the second traction belt, wherein initially an acceleration and then deceleration occurs as the panels reach the second machine.
  • the invention is therefore an object of the invention to provide a method for feeding flat, scaled overlapping metal sheets of the type mentioned, which allows a precise, reproducible conditioning of the respective leading edge of the metal sheets at the leading edge stop. Moreover, a high number of clocks should be feasible.
  • a first, a first conveyor having conveying zone in which the metal sheets are transported at a first constant speed in a shingled arrangement with continuously developed by vacuum or magnetic effect holding effect of a first holding device and a second the first conveyor zone following conveyor zone having a second conveyor, in which the respective leading plate in the region of its leading edge is taken at a first speed and then slowed to a second speed, wherein the distance (b) between the beginning of the second conveyor and the Leading edge of one of the foremost metal sheet subsequent tracing table at the beginning of the slowing down process of the front sheet metal plate is greater than the path that follows the follower board during the slowing down process of the front sheet metal plate. There is an exact table orientation without any edge damage.
  • the scuppered on the first conveyor objects are thus at a constant speed continuously promoted. So there is a dandruff promotion with constant speed.
  • a cyclically changing speed can also be provided. Cyclically changing speed means: high speed, low speed, high speed, low speed, etc., the speed ratio preferably being in the range of 4: 1 to 2: 1, especially 3: 1.
  • the foremost metal sheet seen in the scale as seen in the direction of transport is decelerated by means of the second conveyor, such that it passes against the leading edge stop at a low residual speed or is transferred at the low residual speed of the device leading it against the leading edge stop.
  • the slowing down by the second conveying means can also take place in such a way that the metal sheet is guided by the second conveying means as far as the leading edge stop and comes to a standstill there.
  • the scaly arrangement of the remaining panels is constantly advanced by means of the first conveyor.
  • the scale flow of the first conveying means is cyclically promoted. This means to make a cyclic speed change: high speed - low speed, etc.
  • the procedure according to the invention prevents the follower board from running onto the second conveyor during the deceleration process of the predecessor board and thereby being pre-braked in an undefined manner.
  • the front panel is precisely aligned, it will be in a precisely aligned position by a further processing mechanism accepted.
  • the second conveyor accelerates during the mentioned alignment process back to a speed corresponding to the first conveyor, so that subsequently taken over the now foremost metal sheet of the flake arrangement of the second conveyor and - accordingly slows down as described above and exactly aligned at the leading edge stop.
  • the respective foremost panel rests on the second conveying means, wherein during the slowing down process no relative movement takes place between the second conveying means and the metal sheet and therefore an exact reproducibility is present.
  • deceleration there is no sliding movement between the second conveyor and plate in the main phase.
  • the sheet metal is exactly slowed down with the second conveyor (belt drum) according to a fixed, during each clock same place - machine angle motion law.
  • the below-defined, preferably provided holding effect by vacuum is dimensioned so that the curve of the deceleration is independent of the weight of the panel and the surface finish of the metal sheet.
  • the movement of the second conveyor and plate is synchronous in the deceleration phase, without relative movement. Only shortly before the arrival at the front edge stop, especially at the front marks, this adhesion (by switching off the vacuum) is released, so that the second funding then pushes the metal sheet, but only with a very small force resulting from the now present Friction without vacuum between strand and metal sheet results.
  • the scaling is made such that During the deceleration process of the foremost panel, the overlap zone with the follower panel increases.
  • By appropriate speed tuning of the two conveying means taking into account the formats of the objects to be supplied in each case, a high number of processing per unit time can be realized.
  • the objects rest on the first and the second conveying means that is, the objects are located above the conveying means; Therefore, there is no overhead transport, in which the objects are held on the underside of the conveyor. This is of importance because, among other things, the scaling of the objects is designed in such a way that the front panel is underlaid by the subsequent one, etc., so that the panels are only accessible from below in each case only in the non-overlapped area.
  • the object there is thus a slowdown to a relatively low speed. If the object has assumed this low speed, it slides a short distance over the base and thus passes against the leading edge stop and is aligned there.
  • a further device which detects the object (by gripper device, suction device and / or magnetic device) and defines it up to the leading edge stop, so that the orientation takes place there.
  • the second conveying means to decelerate the object to a standstill, wherein the deceleration is realized in such a way that at standstill or shortly before the standstill is reached, the object occurs against the leading edge stop and is thereby aligned.
  • the distance (c) from the front edge of the foremost metal sheet at the beginning of deceleration to the end of the first holder is greater than the dandruff length, which is the dimension between the leading edge of a metal sheet and the leading edge of a immediately following metal sheet.
  • the respective foremost metal sheet is guided at the second speed against at least one leading edge stop or approaches at this speed the leading edge stop, wherein the front metal sheet is held during its deceleration in a stationary holding zone of a second holding means of the second conveying zone by switchable negative pressure and off this holding action is, as soon as the leading edge of the foremost metal sheet with only a small distance to the leading edge stop, whereby after conditioning and thereby aligning the leading sheet metal plate at the leading edge stop a removal to the processing machine, and wherein the distance (d) between the leading edge stop and the Leading edge of the follower plate immediately following the foremost metal sheet at the time of switching on the holding action of the second holding device is smaller than the distance (e) from the leading edge stop until to the end of the second holding device.
  • a first holding device is assigned to the first conveying means.
  • the second conveyor a second holding device be assigned.
  • the first and / or the second holding device may preferably be designed as a suction device and / or as a magnetic device.
  • the suction device is designed such that the objects, in particular the metal sheets, are held on the surface of the conveying means by suction, so that a relative movement between the corresponding conveyor and the objects is reliably avoided.
  • the braking operation can be carried out without slippage of the metal sheet on the conveyor, so that a high precision is achieved at high cycle speed.
  • the objects are ferromagnetic components, for example steel sheet panels
  • a magnetic device which is located below the conveyor and thus prevents a relative displacement between the metal sheet and the conveyor can also be used as the holding device.
  • the metal sheets thus move exactly at the speed that is predetermined by the corresponding funding.
  • first and second conveying means are therefore strands, which preferably consist of a plurality of parallel juxtaposed belts on which the metal plates rest, wherein below the upper strand, the holding device is arranged, which fixes the metal sheet or the metal sheets on the belt / fix.
  • this section is sufficient and keeps the fixation zone relatively small, so that only correspondingly small amounts of energy are required for the holding effect.
  • the second holding device is located substantially on the upstream half of the second conveying means.
  • the holding action of the second holding device is switched on and off.
  • the vacuum source can be switched on and off or there is a pneumatically acting switching valve in the system, with the suction on and off.
