Definitions

  • the invention relates to a method for aligning a metal sheet when feeding the metal sheet to a processing station, in particular to a stamping press, the feed to and into the processing station being in a first direction (Y axis) of two orthogonal directions (X axis and Y axis) takes place, with the metal sheet being aligned in the first direction (Y axis) in a first alignment step and in the second direction (X axis) being aligned in a second step in order to achieve a predetermined alignment position of the metal sheet, and with the metal sheet being used to Feed is gripped by a gripper arrangement and moved to the processing station and introduced into the processing station and punched in the processing station to generate the desired processing image, in particular punched image, and preferably additionally moved back and forth in the second direction. Furthermore, the invention relates to a device for carrying out the method and a plant for the production of stamped parts with such a device.
  • tin lids or deep-drawn tins - made of steel or aluminium, round or non-round - are mostly produced on high-performance systems.
  • portal presses are used, which enable the use of multiple tools.
  • tools are used in a "zigzag" or line arrangement.
  • the basic material - made of aluminum or steel - is processed in the press in the form of sheet metal.
  • the metal sheets are fed to the tool by means of one or more gripper systems or rollers and then processed step by step.
  • the panels are moved in an orthogonal coordinate system only in the Y direction or in both the X and Y directions. Again for reasons of productivity, panels are processed which are as large as possible. The larger the panels are, the fewer panels have to be coated, cut, fed, etc. In any case, however, the metal sheets must be brought into each punching position with great accuracy.
  • the metal sheets are fed into the system in the form of a stack. Several thousand metal sheets can be stacked on a stack. As a rule, the weight limits the height of the stack.
  • the stacks are placed on chain or roller conveyors and then conveyed to the stacking position either in the production direction of the metal sheet processing in the press or in a 90° direction to the production direction.
  • An electrically or hydraulically driven lifting system raises the stack to a vertical position in which the metal sheets are gripped individually and fed in the direction of the sheet press.
  • the stacks can only be fed to the stacking position relatively imprecisely.
  • the stacking position can therefore vary by up to a few centimeters from stack to stack.
  • the stacks often have stacking errors.
  • the panels may have shifted (fanned out) either during the stacking process in the coil cutting plant or in the painting plant or during transport to the processing plant.
  • Today's modern stacking systems must be able to compensate for such errors.
  • a more accurate centering of the Stacks would require complex and expensive mechanics.
  • the unstacking process of each individual panel using suction pads is also relatively imprecise. When the metal sheet is gripped and fed in the direction of the sheet press, the sheet is also oiled if necessary. Rollers are typically used for this process, which can cause additional inaccuracies in the lateral position of the panel.
  • a sheet fed to the punching press Before a sheet fed to the punching press can be processed in the pressing tool, it must therefore be brought into a defined, precise position in an alignment arrangement. This both in the feed direction to the stamping press and in the direction perpendicular thereto. The accuracy must be in the range of +/- 0.2mm.
  • One reason for this is that the various punching positions in the metal sheet should be as close together as possible in order to achieve maximum material utilization of the metal sheet. Additional reasons can be that the panels can be lithographed (printed) and the punching has to correspond exactly to the printing, or that the remaining web width at the edge of the panel should be kept very small. When processing metal sheets on a sheet press with multiple tools, this is an important criterion in order to achieve high productivity.
  • FIG 1 X and Y axes perpendicular to each other are shown, which are used to describe the feeding of the respective metal sheet to the stamping press and the centering of the metal sheet both for the explanation of the prior art and for the explanation of the invention.
  • the stacker 2 and the press 20 are in the figure 1 also shown schematically.
  • the metal panels are centered in the X and Y direction according to the state of the art, for example using the Figures 2 to 6 shown schematically.
  • the alignment of a sheet stacked from the stack Sheet metal takes place on a centering table 15, which has conveyor belts 3, 4 and 5.
  • figure 3 shows that a sheet metal plate 1 unstacked by the stacker 2 from the sheet metal stack (not shown) has been placed on the centering table.
  • the metal sheet is pushed by means of the conveyor belts 3, 4 and 5 on the centering table 15 in the positive Y direction (Y+ direction), which is defined as the direction toward the press 20.
  • figure 4 shows the panel 1 in a position in which it has been advanced so far in the Y+ direction that the panel 1 is only lying on the conveyor belt 5. This is the reversal position, from which the panel 1 is moved in the negative Y direction (Y-) by the conveyor belt 5 for centering or alignment, ie it is moved a little further towards the stacker 2 .
  • figure 5 shows how, after being pushed with the conveyor belt 5 in the Y-direction, the metal sheet 1 rests against two stops 6 and 7, which have been raised above the table level for this purpose.
  • the panel is centered or aligned in the Y axis.
  • a stop 8 is positioned in the X+ direction close to the panel and finally a slide or further stop 9 pushes the panel in the negative X direction (X-) against the stop 8 so that the sheet metal panel is in the centered or aligned position 1 according to figure 6 results.
  • the alignment in the X and Y direction can be combined in another embodiment according to the prior art, for example by a spring-loaded vacuum gripper system pushing the panel against an X+ and Y- stop.
  • DE 43 45 184 A1 shows a centering system in which a centering station, referred to as an alignment station, is designed for metal sheets with two lateral stops and a rear stop for the metal sheet.
  • a gripper 11 is shown for this purpose, which grasps the panel 1 in its previously centred/aligned position at its rear end and feeds it onto the press 20 in the Y+ direction.
  • the gripper that advances the metal sheet in the Y+ direction and, if necessary, moves it in the X and X+ direction in order to produce the desired stamping pattern can be the same gripper that holds the centered panel 1 in the position of figure 6 grabbed.
  • a second gripper can be present, which has taken over the panel 1 from the first gripper in front of the press 20 .
  • the alignment and centering mechanism explained according to the prior art is complex and requires maintenance. Furthermore, this mechanic needs some time to align the board. During the centering or alignment process, the handling system or the gripper must not yet take over the sheet metal. On the one hand because the alignment is not yet complete and on the other hand because the alignment mechanism could cause a collision with the gripper.
  • the object of the invention is to create an improved method for aligning a sheet metal panel when the sheet metal panel is fed to a processing station.
  • the method should enable less maintenance and more rapid feeding to the press.
  • the position of the gripping assembly is adapted to the detected, deviating in the second direction position of the panel by correspondingly displacing the gripping assembly in the second direction to cause the panel to be gripped in place.
  • the object of the invention is therefore to omit the sheet metal displacement in the X axis, or the second direction, as a separate alignment step. Instead, the position of the panel in the X axis is detected by at least one sensor, preferably without contact, so that this position can be identified in a control device connected to the sensor. Instead of first bringing the panel into a defined X position and then only transferring the panel to the gripping arrangement, only the X position of the sheet metal panel is initially recorded.
  • the controller calculates the transfer position for the gripping arrangement and the gripping arrangement brings the metal sheet into the correct position with regard to the X axis when it is fed to the processing station or compensates for the deviation from the predetermined alignment position determined by the sensor device and the control device in the second Direction. This means that no alignment parts need to be adjusted and maintained for alignment in the X axis.
  • the position in the second direction is preferably determined by a stationary sensor, which results in a simple and robust structure.
  • the position in the second direction can be determined by a movable sensor, in particular by a sensor being arranged on the gripping arrangement and being moved by it over the sheet metal panel. In this way, a movable sensor can be used be, which can simplify the structure of the sensor used without requiring additional mechanics for the movement of the sensor.
  • a line sensor with or without a reflector can be used as the sensor of the sensor means, or else a camera with image processing.
  • the sensor may be located above or below the panel position, or it may be a sensor provided both above and below the panel position.
  • the invention is also based on the object of creating an improved device for aligning a metal sheet when the metal sheet is fed to a processing station, in particular to a stamping press.
  • the device should enable less maintenance and faster delivery to the processing station or press.
  • the object of the invention is therefore also with the device to avoid the metal plate displacement in the X axis or the second direction as a separate alignment and instead to make the position of the plate in the X axis detectable by at least one sensor, so that this Position can be seen in a control device connected to the sensor.
  • the device Instead of first bringing the panel into a defined X position and only then transferring the panel to the gripping arrangement, the device initially only allows the X position of the sheet metal panel to be detected.
  • the control calculates the transfer position for the gripping arrangement based on the values received and the gripping arrangement brings the metal sheet into the correct position with regard to the X axis when it is fed to the processing station. It is therefore not necessary to adjust and maintain any alignment parts for the alignment in the X axis with the device.
  • a stationary sensor is provided to determine the position in the second direction, which results in a particularly robust and maintenance-free device.
  • a movable sensor of the sensor means is provided to determine the position in the second direction, in particular that the sensor of the sensor means is arranged on the gripping arrangement and can be moved by it over the sheet metal panel, which has the advantage for Movement of the sensor does not have to use any additional mechanics, since the gripping arrangement is designed to carry out the required movement anyway.
  • a line sensor with or without a reflector can be provided as the sensor, or a camera with image processing can be provided as the sensor.
  • the sensor means can comprise sensors arranged above or below the sheet metal position.
  • the invention is also based on the object of creating an improved system for producing stamped parts from metal sheets.
  • the procedure for feeding a metal sheet to a stamping press for aligning the metal sheet in the correct position for introducing the metal sheet into the stamping press is to set the alignment position in the feed direction by means of stops. Alignment in the second direction orthogonal to the feed direction takes place in such a way that the position of the metal sheet in the second direction is determined by at least one sensor and a control device, and the deviation of the metal sheet from the predetermined alignment position in the second direction is determined by the control device. Thereafter, alignment in the second direction is performed by means of the gripping assembly provided for feeding the metal sheet to the stamping press, by controlling the gripping assembly to compensate for the deviation and correctly align the metal sheet.
  • figure 7 shows a centering table 15 of an embodiment of the invention, in which a sensor means 16 with at least one sensor and any lighting means and/or reflectors is provided, which sensor means the position of the edge of a sheet metal plate that comes to lie on the table in the detection range of the sensor means in of the X coordinate, which will be explained later.
  • a control device 18 which receives the signal from the sensor means 16, the position of the metal plate in the X coordinate can be detected or the deviation of the metal plate 1 from the desired predetermined alignment position in the X coordinate.
  • the gripping assembly is not shown to simplify the figures. A gripping arrangement is available and will later on hand figures 10 , 11 and 12 explained.
  • Conveyor belts 3, 4 and 5 are also shown, by means of which the respective metal sheet 1 can be moved back and forth on the centering table in the Y coordinate direction.
  • other means can also be provided for this movement, for example rollers arranged partially sunk in the table.
  • the table 15 can be provided, in a known manner, with means facilitating the movement of metal sheets on the table, for example with regularly arranged rolling elements or with means for generating air cushions. Such is known to the person skilled in the art and is not explained further here.
  • figure 8 shows a sheet metal 1, which has been placed on the centering table and first the conveyor belts 3 and 4.
  • the metal plate is aligned in the Y direction by means of the conveyor belts 3, 4 and 5, in that the metal plate 1 is first advanced in the Y+ direction. If the metal sheet has reached a position in which it only rests on the conveyor belt 5, as in figure 9 shown, it is pushed in the Y (Y-minus) direction against two stops 6 and 7, as has already been explained in the prior art, and here in figure 10 is shown.
  • This is the preferred way of aligning in the Y direction.
  • Other known types of alignment in the Y direction can also be used.
  • the sensor means 16 comprises at least one stationary sensor 17 with a longitudinal extent in the X coordinate direction.
  • This sensor is, for example, a line sensor that has a large number of light-sensitive sensor elements arranged in a row and is therefore a Can emit a signal that can determine the position of an object above the sensor, which sensor elements are obscured by the object and which are not obscured.
  • a sensor is arranged in a recess 13 in the table top in such a way that it comes to lie below the metal sheet 1 in each case.
  • it is arranged in such a way that, when the metal sheet 1 is aligned in the Y coordinate, it can emit the position of the edge 1′ over the sensor in the X coordinate as a sensor signal.
  • the edge 1' of the sheet metal 1 lies over the sensor, so that a part 17' of the sensor is covered by the sheet metal 1.
  • the part of the sensor of the sensor means lying in the X+ direction, which is not covered by the sheet metal panel 1, is denoted by 17".
  • the sensor is connected to a control device 18, which evaluates the sensor signal and thus the deviation in the position of the sheet metal panel 1 in the X coordinate of the desired alignment position of the metal sheet.
  • This control device also controls the drive of the gripper 11 of the gripping arrangement.
  • the detection of the exact position of the metal sheet by the sensor means can be carried out using only one sensor, e.g.
  • Lighting means and/or reflector can be designed, or the sensor means can comprise several sensors whose signals are evaluated in the control device.
  • the sensor means can also comprise an optical system, such as a camera with image processing, which is used in addition to a sensor or instead of a sensor Sensors or cameras of the Sensormitt els can be arranged above the sheet metal position and/or, as shown in the example, below the sheet metal position. Multiple detection can also be provided for reasons of accuracy.
  • the detection of the sheet position can be done on one edge or the other of the sheet, or for scrolled sheets that have two edges on each side, the This can be done on both edges of one side or on both edges of one side or both sides.
  • the sensor means can also include a detection of the sheet metal edge by means of at least one movable sensor.
  • a sensor of the sensor means can be arranged on the gripper 11 and to determine the position of the metal plate, the control device moves the gripper 11 over the metal plate in such a way that its position in the X coordinate is determined. Since the control device is known to know the position of the gripper of the gripping arrangement, it can also in this case derive the position of the sheet metal from the sensor signal. In this case, a line sensor can be dispensed with and a simpler sensor can be used.
  • the sensor means can also comprise a sensor that can be moved separately from the gripper.
  • a movable proximity switch can be provided.
  • the sheet edge can be detected by means of a time calculation. Since the initial position of the sensor is known and the speed of movement of the sensor is known, the time at which the sensor detects the edge of the sheet metal can be recorded. An exact position can be derived from this time. However, for the reason mentioned above that they are maintenance-free, preference is given to sensor means which work with a stationary sensor or with a stationary camera or with a movable sensor arranged on the gripper or with a camera arranged on the gripper.
  • the deviation can subsequently be corrected during the feeding or the transport of the metal sheet to the press.
  • the sensor 17 of the sensor means and the control device 18 have determined a deviation ⁇ X of the position of the metal sheet in the X coordinate from the desired orientation or centering. This deviation is now corrected by the gripping arrangement.
  • the deviation of the alignment position from the predetermined alignment position in the second direction (X axis) is corrected after the metal sheet has been gripped by means of the gripping arrangement, in that the gripping arrangement, controlled by the control device, moves the metal sheet into the predetermined alignment position in the second direction during the feed movement of the metal sheet to the processing station.
  • the gripping arrangement with the gripper 11 which, as is known, can be moved by the control device in the X and Y direction by means of corresponding drives of the gripper, first executes a movement in the X (Xminus) direction in order to correct the amount ⁇ X and then carries out the movement towards the press 20 in direction Y+.
  • a combined X and Y movement of the gripper 11 is preferred, so that it is moved in the direction of the arrow K, with the movement in the X ⁇ (Xminus) direction only taking place until the deviation ⁇ X is eliminated.
  • the position of the gripping arrangement is adapted to the detected position of the panel which differs in the second direction by the gripping arrangement being correspondingly displaced in the second direction in order to cause the panel to be gripped at the intended location.
  • this is shown by the gripper 11 of the gripping arrangement also being displaced essentially by the amount ⁇ X in the second direction prior to gripping, by which to grip panel 1 in the place provided for this purpose.
  • the gripper 11 brings the metal sheet into the press 20 and carries out the known punching movement in the X and Y directions, which figure 11 is shown.
  • the gripping arrangement can also have two grippers, between which the metal sheet 1 aligned by the first gripper is transferred.
  • the gripper 11 from figure 10 then performs the corrective movement in the X (Xminus) direction and the Y movement towards the punch press and performs all punching of at least one row of the punching pattern (usually two or three rows of punching), after which a second gripper of the gripping assembly takes over the sheet metal and completes the punching while the first gripper is moved back to take over the following metal sheet.
  • figure 12 shows a known gripper of the gripping arrangement as it is already used in conventional devices and as it is also used for the present invention.
  • the gripper 11 can be moved in the X direction and Y direction by appropriate drives, which drives are controlled by the control device.
  • the gripper has two tongs 19, by means of which the sheet metal plate can be gripped at its rear edge, seen in the Y+ direction, and can also be released again. This is known and will not be explained further here.
