Definitions

  • the invention relates to a method for setting a flexer station for the pretreatment of metal sheets prior to rounding thereof, wherein in the flexer station a desired impact position of the metal sheet on a measuring plate serves as a measure for the adjustment of at least one adjustable element of the flexer station.
  • the invention further relates to an application of the method when welding container frames.
  • the invention relates to a flexer station with at least one adjustable flexer element.
  • the invention relates to a round apparatus with such a flexer station and a welding apparatus for the production of Be fiscalerzargen with such a round apparatus.
  • This process may need to be repeated several times until the correct setting is found or the correct rounding is achieved for the subsequent rounding station of the rotary apparatus.
  • screws When adjusting the wedge, screws must be loosened, some of which can be difficult to access, and in most cases, round wedges must also be removed, so that the place of impact of the sheet on the measuring plate is clearly visible.
  • Methods and devices of the type mentioned are generally used in the sheet metal industry for the rounding of sheets, but especially in the production of container frames, especially can bodies, made of sheet metal.
  • the Be fiscalerzargen blanks are transported to the rounding directly into a welding machine for welding the longitudinal seam of the frame.
  • the stacking of the sheets, the round apparatus and the welding machine form a unit.
  • Corresponding plants for can production are for example DE-A-33 30 171 or from the mentioned US-A-5,209,625 known.
  • the rounding takes place in such a way that the can body formed can be guided directly into the Z-rail used for the seam overlap.
  • the rectangular cut sheet metal sections with defined dimensions and material properties recorded in standards are pushed by a slide-in system into a first, driven transport roller pair, of several driven transport rollers at a speed of 100-450 m / min. transported further and bent in the round apparatus with a round system with the help of wedges with rollers or with roller systems to a round frame.
  • a slide-in system into a first, driven transport roller pair, of several driven transport rollers at a speed of 100-450 m / min. transported further and bent in the round apparatus with a round system with the help of wedges with rollers or with roller systems to a round frame.
  • an advance plastic deformation as explained.
  • the inventive method eliminates the manual spinning of the sheet through the round apparatus or the flexer station, as determined by the sensor arrangement, the impact position in motor operation.
  • the actual impact position or actual impact position on the measuring plate can be displayed on a display device, wherein preferably also the desired position is superimposed.
  • the operator can then manually set an adjustable element of the flexer station so that the deviation from the target impact position is lower and zero possible.
  • the target impact position is known in the art and depends on the sheet to be rounded and the rounding speed.
  • a signal derived therefrom can be displayed, eg directly a numerical value for the adjustment of an adjustable element of the flexer station.
  • the signal representing the impact position can be used to automatically set an element of the pretreatment by the flexer station. In any case, a lesser amount of time, since the impact position no longer needs to be determined by the operator visually on the measuring plate itself and the necessary expansion of round elements (wedges) is avoided.
  • the method of adjusting the flexer station is preferably used when rounding container frames for their welding on electric resistance seam welding machines, wherein individual sheet metal sections in series and at high speed of 100-450 m / min go through the flexer station and the round station and then the welding device. Accordingly, the adjustment is also made on the basis of an impact position, which has been determined with the speed corresponding to the later speed in the rounding in series production.
  • the object is achieved in that the flexer station has a sensor arrangement and a control by which the impact position of the test sheet on the measuring plate in the motor-driven sheet metal pass through the flexer station can be determined, whereby a signal representing the position is provided by that the impact position or a value derived therefrom can be displayed on a display device, and / or by the pretreatment of the sheets in the flexer station determining element thereof by the controller and a drive is adjustable so that a deviation from the target impact position is reduced.
  • the invention further relates to a round apparatus with such a flexer station and a welder for Be marryerzargen with such a round apparatus.
  • the rounded Be Strukturerzargen-blanks are fed from the rounding machine of a welding device for can bodies with welding rollers, in particular with thereon running wire intermediate electrodes, and a Z-rail for positioning the Zargenkanten.
  • the measurement of the impact position therefore takes place at a flow rate in the range of 100 to 450 m / min. to determine the impact position at operating speed.
  • a flexor wedge following the flexer rollers is preferably set on the basis of the signal.
  • the measurement of the impact position is preferably carried out electrically by electrical contact production on the measuring plate by the impinging sheet.
  • FIGS. 1 and 2 show schematically in side view embodiments of the present invention, wherein as an example the setting of a flex station in a rounding machine for the rounding of successive sheet metal sections is shown, as it is used in the series production of container frame blanks or when welding container frames, in particular can bodies ,
  • the invention can also be used for the setting of flexer stations in any other rounding operations or round machines.
  • sheet metal sections of which the sections 1 and 2 are shown as examples, are stacked by a stack 10 and fed into a transport device 3, which serves as a feed line for a rounding machine 4, which has the flexer station.
  • the sheets pass through this arrangement of feed line and rounding machine in the direction of arrow A.
  • the stacking of the stack 10 and the introduction into the transport device 3 is here, since this is known in the art, not further explained.
  • the transport device 3 is also considered to be optional, although preferred, so that the sheets could also be dispensed directly from the stack 10 into the rounding machine 4.
  • the transport device 3 is equipped with a plurality of roller pairs, which promote the respective sheet metal section to the input 19 of the rotary apparatus 4, where in this example the flexer station 50 begins with a first element 20.
  • the promotion could also be carried out in other ways than with the roller pairs shown.
  • each sheet metal section is rounded to a frame blank, as can be seen for the front part of the sheet metal section 2 in the direction of passage.
  • the rounding is done with a predetermined by the setting of the rounding machine Sollrundungsradius and leads to the rounding radius R; this with a rounding speed VR of eg 100 to 450 m / minute, in particular when rounding can body blanks.
  • Round machines are known in various embodiments, especially for can bodies, the round machine can be provided in a simple form as two-roll rounding machine with the two rollers 11 and 12. Also round machines with a plurality of rollers are known, such as from EP-A-1 197 272 , Preferably, the rotary apparatus is controllable in its setting for determining the rounding in the rounding operation. In the present embodiment, it is shown that a Vorrundkeil 14 may be provided in front of the round rollers 11 and 12. Likewise, a round wedge 13 may be provided after the round rollers 11, 12. Before the actual rounding station of the rotary apparatus 4, the flexer station 50 is provided, which in the embodiment shown is part of the round apparatus, which could also be a separate station.
  • the flexer station has the rollers 9 and 8 and the flexing wedge 7, which acts on the plate emerging from the rollers, as well as the mentioned wedge 20 at the entrance of the flexer station.
  • the flexer station is used for pretreatment and removal of stresses in the sheet, as explained and eg from the above-mentioned US 5,209,625 known.
  • At least one element of the flexer station is adjustable to adapt to the sheet material to be rounded and the rounding speed, which is known, wherein the setting before the beginning of the actual Rounding operation or in the case of Be dockerzargen before the series production takes place.
  • This element can be manually adjustable, as known, or a controllable motorized adjustment can be provided. Preference is given to the setting of the mentioned flexor wedge.
  • the preferably driven adjustable elements of the flexer station, and possibly also rounding elements of the rounding machine are provided with drives (hereinafter called actuators), which can move these elements within their usual adjustment options to allow the control of the flexer station setting.
  • the influence of the actuators on the elements of the flexer station and, if provided, also on the elements of the round machine is symbolized in the figures by an outgoing from the actuator arrow into the respective element, the movement of the element by another arrow.
  • the connection of the actuators with the controller 5 is symbolized by lines 40.
  • the flexi wedge 7 is moved by the actuator 6 in the direction of the arrow B. This also corresponds to the manual adjustability of the wedge, if no actuator is provided for the adjustment. If according to FIG. 2 an adjustment of the flex roller 9 is provided, it is done by an actuator 29 in the directions of the arrow C, or at most manually in a corresponding manner.
  • the preliminary circular wedge 14 can be moved by the actuator 15 in the direction of the arrow E.
  • a distance between them determining drive can be provided, which acts on one or both of the rollers and which is shown as an actuator 16 schematically.
  • the actuator 17 can act on the circular wedge 13 in order to move it in the direction of the arrow D. All of these actuators can be provided or only one of them and any combinations are possible.
  • the sheet 1 located therein for pretreatment reaches the target impact position x on the measuring plate 38.
  • This desired impact position is known in the prior art for a given sheet material and an intended rounding speed in the subsequent rounding station of the rounding machine. If the sheet reaches the impact position x on the measuring plate 38 in the Flexerstation 50 at the intended speed for the rounding, the setting of the flexer station is correct. If the sheet metal 1 hits too early, for example at the impact position y, as shown by a broken line, an element of the flexer station 50 must be adjusted in order to place the impact position as close as possible to the point x.
  • the flexi wedge 7 is adjusted, in this example, an adjustment in the directions of the arrow B is possible. This can be done manually or by the actuator 6.
  • This actuator can be controlled manually or preferably by the controller 5 of the flexer station, which may also be the control of the rounding machine.

  • the impact position of the sheet on the measuring plate is now determined by a measuring device with a sensor arrangement.
  • This can be any sensor arrangement which can determine the position of the sheet at which it impinges on the measuring plate.

  • the determination of the impact position by an electrical contact of the sheet on the measuring plate 38.
  • the time is determined until the sheet - starting from a certain initial position - impinges on the measuring plate.

  • the measuring device has at least one sensor 45, with which the arrival of the respective sheet 1 can be detected at or in the measuring device.
  • the front edge of the sheet in the transport direction A is detected, in particular by an optical sensor, in particular a light barrier or a plurality of light barriers. This detection of the sheet 1 starts a time measurement at time t 0 in the measuring device.
  • time measuring means This can be done by a separate time measuring means or by the controller 5, which has already been mentioned, and which controls in this case, the measuring device or is part of the same and receives the sensor signal of the sensor 45.
  • FIG. 2 shows the time measurement is terminated at time t 1 at which the leading edge of the sheet strikes the measuring plate 38, which is reported to the controller 5 via a line 38 '.
  • the time t 1 is different according to the setting of the flexer station and thus provides a measure of their adjustment.
  • the time t 1 would be shorter if the time measurement would be terminated when hitting the point y or longer, if they would be terminated by the impact at the point y '.
  • the determined by the measuring device time can thus be converted to the position of the impact position, since the transport speed of the sheet is known by the flexer station.
  • the measuring device, or in this example the controller 5, can thus represent the impact position on a display 25, which will be explained in more detail and if necessary via at least one actuator of the flexer station cause a corrective adjustment of an element of the flexer station, if the measured impact position deviates from the desired impact position.

If the leading edge of the electrically conductive sheet meets the measuring plate 38, the two potentials are short-circuited, which can be determined by a corresponding current flow or a corresponding voltage drop of the measuring voltage. Thus, the time measurement is stopped or the time between detection of the leading edge by the sensor 45 and the impact of the leading edge is determined on the measuring plate 38 and thus the impact position of the sheet in the flexer 50. For coated sheets, the electrical contact between the rollers.

  • the voltage drop detection is indicated by the voltmeter symbols in FIG. 4 represented and can be done in any manner known in the art by the measuring device or in this example, in particular by the controller 5.
  • the electrical resistance R is chosen so large that the short-circuit current remains within a desired limit.
  • the impact position is displayed on the optical display 25, which may be a screen or other display device.
  • the optical display 25 may be a screen or other display device.
  • This can for example be done so that a line is displayed, which corresponds to the, at most shortened, longitudinal extent of the measuring plate on which a point is displayed, which corresponds to the impact position.
  • the operator thus receives the same information per se, which is available in the prior art by exposing the measuring plate and their visual inspection when hitting the sheet. The operator can then judge whether the point of impact is at the desired location or not and, if necessary, manually adjust an element of the flexer station, in particular the flex key 7.
  • the display also shows the target impact position x or an allowable one Range is displayed so that the operator the actual impact position, such as y or y ', can easily relate.
  • a derived value displayed for example, a value by which an element of the flexer station must be manually adjusted to move from the achieved actual impact position to the target impact position.
  • a value of +5 can be displayed if the flex key 7 has to be adjusted by 5 units on the basis of a scale located there.
  • the measuring device in particular the controller 5, can calculate this derived display value +5 from the deviation of the measured actual impact position from the target impact position.
  • the operator can adjust the flexer element by means of a motor drive or by means of an actuator, wherein, however, the control of the actuator is performed by the operator.
  • a feedback of the actuator to the controller 5 an indication of the setting on the display 25, so that the operator can control whether it performs the adjustment properly as reducing the deviation of the actual impact position of the target impact position.

  • the adjustment of the flexer element is not made manually, but directly via the actuator by the controller 5 in dependence on the difference between the measured actual impact position for target impact position.
  • the flexi wedge 7 can be pivoted by the controller 5 by means of the actuator 6 upwards to move the actual impact position for the next sheet from the position y to the position x. By another test sheet, the correct adjustment of the flexure wedge can then be verified.
