Definitions

  • the invention relates to a method according to the preamble of claim 1 and an arrangement for performing the method.
  • Such a method and a device for carrying it out is known from DE-PS 29 34 115.
  • the moving strip material is then temporarily brought into the form of a strip roll and stored, and then removed again from the wound state for continuous further processing or treatment, the strip lengths to be welded being recorded in their end and beginning areas and then jointly from opposite sides can be wound in two layers on a reel in the same direction.
  • the drum-shaped reel consists of two halves, which contain the welding device, so that the welding process goes through during the rotation of the drum can be led. This process has compared to the previously practiced processes in which the I.
  • the tape material had to be temporarily stored in the form of a tape wrap in one layer on a large drum, but which also required a so-called inlet twist section and an outlet twist section of relatively large length, the advantage that its space requirement is considerably less.
  • this method does not require a single drum. Rather, a continuous process over a longer period of time requires a number of drums changing in their positions and also also requires a buffer section for accommodating the strip material which arises when the drums are regrouped.
  • the object of the invention is to further reduce the technical and spatial outlay required for the above-described method.
  • the advantage achieved thereby consists primarily in the fact that the relatively complicated two-part drum construction and the relatively complex regrouping of such drums can be dispensed with, as can an additional band buffer.
  • An arrangement for carrying out the invention Ver - driving is characterized in claim. 6
  • This arrangement has the advantage that, because of the relatively large drum diameter of the single storage drum, the welding device is not restricted in space and is relatively easily accessible. Otherwise, the arrangement is so constructed that it is simple, appropriately controlled and unchanged in its mutual position Rotary drives get along. In particular, the omission of the regrouping drives results in a considerable simplification of the technical effort and thus also the susceptibility to malfunction of such a system.
  • a laser welding device as a welding device, such as is described in EP-A-0 101 016.
  • Fig. 1 The arrangement described in Fig. 1 has a disc-shaped, mounted in its central axis mounting plate 1.
  • a number of rollers 2 are rotatably mounted about horizontal axes, the axes of which are parallel to the axis of rotation of the mounting plate 1 and which at one end the mounting plate 1 and at its other end on a mounting ring 3 (Fig. 2) are mounted radially.
  • each roller axis has hydraulic cylinders 4 on both bearing sides assigned that allow an individual radial displacement for each role within corresponding recesses 5 in the mounting plate 1 and the mounting ring 3.
  • the welding device 12 is arranged in the space between the reel mandrel 11 and the rollers 2 of the roller ring 9.
  • This consists of a support 13, which can be moved by spindles 14 in the direction of the central axis of the drive shaft 11 by a support drive 15.
  • the spindles 14 are rotatably mounted below the rollers 2 on the mounting plate 1 and the mounting ring 3.
  • the support 13 works in conjunction with a clamping device 16, which is described in more detail in FIG. 5.
  • the support 13 includes a pivotable planer 17 and the last deflecting mirror 18 of a laser welding arrangement, the energy beam generator 19 of which is located outside the arrangement and the beam 20 of which passes through the drive shaft 6 designed as a hollow shaft, via a first deflecting mirror 21 in the direction of the welding device 12 and through one second deflecting mirror 22 in the direction of the support 13 and from there through the last deflecting mirror 18 is finally directed onto the weld seam.
  • All of the control functions to be coordinated for the control of the process sequence, both for the commissioning and for the control of the drive units and the sensors, are carried out via control modules by a control computer 24 in accordance with the control program input to it.
  • the drive motor 25 for the roller ring 9, via the control line 26, the drive motor 27 for the reel mandrel 11 of the supply coil 23 via the control line 28, the support drive 15 via the control line 29, the two proximity switches 30, 31 for the support drive via the control lines 32, 33, the motor 34 for the feed drive roller 35 via the control line 36, the drive motor 37 for the exit driver roller 38 via the control line 39, the energy beam generator 19 via the control lines 39, the electrohydraulic converter 8 via the control line 40 and the Electrohydraulic energy converters 42 are connected via the control line 41 to control modules 43 to 52 connected to a central control computer 24. This is connected via a further control line 53 to the central computer (not shown) of the processing system.
  • a supply coil 23 is first introduced into the center of the roller ring 9 with the aid of the reel mandrel 11, so that it assumes the position shown schematically in FIG. 2.
  • the reel drive motor 10 is then put into operation until the beginning of the supply coil passes through the funnel-shaped guide plates 54, 55 between the feed driver roller 35 and the feed pressure roller 56.
  • the reel drive motor 10 is switched off and the hydraulic cylinder 57 of the feed pressure roller 56 is put into operation, so that the beginning of the supply coil between the feed drive roller 35 and the Feed pinch roller 56 is clamped.
  • the drive motor 34 of the feed drive roller 35 is switched on, so that the belt between the open feed jaws 58 and the also open output jaws 59 passes between the output drive roller 38 and the output pressure roller 60.
  • the hydraulic cylinder 61 of the exit pressure roller 60 is actuated, the hydraulic cylinder 57 of the feed pressure roller 56 is released and the drive motor 37 of the exit door roller 38 is switched on, so that the belt - possibly via further guide means, not shown - between two roles of the roller ring came out.
  • the outgoing strip start is fed by a gripper (not shown) to the still stationary processing system (also not shown).
  • the roller ring is put into a rotational movement which is the same as the winding direction of the supply coil 23 and opposite to the direction of movement of the strip by starting up its drive motor 25, so that the strip is wound from the supply coil 23 onto the outside of the roller ring and forms a storage coil 62 there.
  • the hydraulic cylinders 4 of each roll are actuated via the hydraulic-electrical converter 8 in such a way that the respective roll can yield so much layer by layer in the direction of the pivot point that the individual layers are wound against one another against a desired pressure.
  • the drive motor 25 remains switched on in this direction of rotation until the strip is almost unwound from the supply coil 23 and reaches the feed drive roller 35.
  • the energy beam generator 19 of the laser welding device is turned on switches and at the same time the support drive 15 moves in the opposite direction of rotation, so that the laser beam is guided with the aid of the deflecting mirrors 21, 22 and 18 and a focusing device, not shown, over the sheet metal edges and welds them.
  • the support drive 15 and the energy beam generator 19 are switched off by a corresponding pulse from the proximity switch 31, the support drive 15 is switched on again in the opposite direction of rotation and the planing tool 68 is pivoted back into its working position.
  • the planing tool 68 is adjusted by means not shown so that it now planes the weld.
  • the proximity switch 30 again interrupts the support drive 15.
  • the hydraulic cylinders 64, 65, 66, 67 are relieved, so that the clamping jaws 58, 59 open.
  • the drive motor 37 of the exit drive roller 38 is switched on and the direction of rotation of the drive motor 25 of the roller ring is reversed, so that the roller ring rotates clockwise again and the tape located on the supply coil is in turn wound onto the roller cage via the roller 62 as a storage coil. This process continues until the end of the strip has left the supply coil and has reached the feed drive roller 35. Then the process already described is repeated.
  • the dimensions of the system and the speeds are chosen so that the storage coil is completely unwound after the completion of each processing operation.
  • the principle of the method is therefore to concentrate the contents of a storage coil with a small diameter into the storage coil during the processing process tric surrounding storage coil to transfer significantly larger diameter, weld both coils while the storage coil is running and insert a new storage coil.
  • there is a sufficiently large annular space between the two coils for accommodating the clamping and welding device, and on the other hand there is sufficient time for the welding process to be carried out.
  • FIGS. 1 and 2 can be modified such that the supply coil 23 is not around the outside of the roller ring. but is wrapped around the inside. This makes it possible to arrange the roller ring fixed.
  • the supply coil 23 is unwound and the tape is applied with the aid of the clamping and welding device which executes a rotational movement about the central axis of the roller ring.
  • the basic structure of this arrangement can be seen from FIGS. 3 and 4.
  • the rollers 2 are in turn rotatable about their central axis on the one hand on a mounting plate 74 and on the other hand on a mounting ring 75, both of which are firmly anchored.
  • the deflecting mirrors 21 and 22 are arranged in the edges of these beam channels and direct the energy beam onto the deflecting mirror 18, which guides it in the direction of the weld seam.
  • the motor 25 for the angle arm of the clamping and welding device 12, 16 is put into operation and now moves it clockwise around the central axis of the arrangement, so that the storage coil is unwound. Meanwhile, a new supply coil is retracted and the motor 10 is switched on, so that the supply coil also rotates clockwise at such an angular speed that the beginning of the band through the funnel-shaped sliding plates 54, 55 into the clamping and welding device rotating in the same direction in that described Way can be threaded. The welding device is then actuated in the manner described, so that the strip edges are welded.
  • the motor 25 is stopped and put into operation again in the opposite direction of rotation (counterclockwise), so that with the help of the exit driver roller 38 with the pressure roller 60 the supply coil is unwound and the storage coil is in turn wound against the inside of the roller ring. This process is repeated accordingly, so that continuous operation is ensured.
  • some of the rollers 2 of the roller ring can be arranged so as to be radially movable either against spring pressure or by corresponding positive adjustment.
  • the formation of the storage coil 62 occurs either by winding the tape stored on the supply coil 23 onto the outer circumference of the rotatable roller ring 9 (FIG. 1) or by applying the tape to the inside of the fixed roller ring 9 (FIG. 3 ).
  • these arrangements can be used with the corresponding methods. If these material properties are not available, these methods described above can lead to difficulties insofar as the tape contracts to form a polygon on the roller ring 9 in the arrangement according to FIG. 1 or the first layer of the supply coil does not overlap in the arrangement according to FIG. 3 creates the entire circumference on the rollers 2 of the roller ring 9.
  • FIG. 7 a so-called forming roller cage (FIG. 7), in which rollers 79, which have the same width as the rollers 2, are arranged around them are that the storage coil 62 is guided and formed between the roller rings formed by the rollers 2 and the rollers 79.
  • the rollers 2 of the roller ring 9 are in turn radially displaceable, so that the space available between the two roller rings mentioned above can be adapted to the winding diameter of the storage coil.
  • FIG. 7 forming roller cage in which rollers 79, which have the same width as the rollers 2, are arranged around them are that the storage coil 62 is guided and formed between the roller rings formed by the rollers 2 and the rollers 79.
  • the rollers 2 of the roller ring 9 are in turn radially displaceable, so that the space available between the two roller rings mentioned above can be adapted to the winding diameter of the storage coil.
  • auxiliary drum 80 which is fixedly connected to the welding and clamping device 12, 16 and rotatably mounted concentrically to the idler ring 9, the cylinders of which provide the space for surrounds the supply coil and the welding and clamping device, the width of which corresponds to that of the idler ring 9 and the diameter of which is smaller by the thickness of the auxiliary coil than the smallest inner diameter of the idler roller ring of the idler drum and the slot at the height of the exit drive roller 38 of the clamping device 16 Has passage of the rolled strip.
  • the cross section of the arrangement shown in FIG. 10 shows the drive mechanism of the concentrically arranged functional elements.
  • the motor 28 drives the reel mandrel 11, which is supported on one side in the front bearing 82 and in the rear bearing 83, via a multiple spline shaft 81.
  • the auxiliary drum 80 which is mounted so that it can be rotated concentrically about the reel mandrel 11 via a bearing bush 84, is driven concentrically to the reel mandrel by a motor 85 via a pinion-ring gear transmission 86.
  • the roller ring 9 of the support rollers 2 is fastened to a support ring 91 which is concentrically rotatably mounted on the bearing bush 84 of the auxiliary drum 80.
  • This mounting plate is driven by a motor 87 via a pinion gear transmission 88.
  • a positioning disk 89 is fastened thereon, which can be displaced in the axial direction by such a stroke by hydraulic cylinders 90 that center deviations of the strip running off the supply coil can be corrected.
  • the support rollers 2 are moved radially in the direction of the axis of rotation by means not shown by such amounts that the storage coil can build up inwards (FIG. 8).
  • the aforementioned drive motors are stopped and the reel mandrel 11 is fed a new supply coil.
  • the welding process begins with the auxiliary drum 80 stationary.
  • the further processing system and the drive motor 87 for the roller ring 9 are put into operation in the opposite direction of rotation.
  • FIGS. 7 to 10 Another advantage of the arrangement shown in FIGS. 7 to 10 is that the welding process can be carried out even when the welding device is at a standstill.
