Definitions

  • the invention relates to a method according to the preamble of claim 1 and to devices according to the preamble of claims 2 and 11 respectively.
  • the invention is based on the knowledge that at least some of the phenomena described above may be due to the centering, and this results in the task of creating an improved centering method, making the system cheaper and enabling a shorter overall length. This is achieved in a surprisingly simple manner by the features of the characterizing part of claim 1.
  • a safe actuation of a band clamping device on a coil in an unwinding station can be achieved by a device according to claims 11 and 12, respectively.
  • a straightening machine 22 is supplied with strip-like material 4.
  • This band-shaped material 4 is at the right end of Fig.1 unwound from a coil 2 at a roll-off station 1.
  • the strip-shaped material 4, which, as can be seen, lies in a vertical plane from the coil 2, since the coil is unwound with a vertical axis of rotation 5, passes through a strip transport and twisting device 20, which in itself is similar to that of FIG. 9 EP-A-0 267 357 could be formed.
  • the band-shaped material 4 is aligned on centering rollers 6, at the center of feed rollers 21, which - in the direction of movement of the belt 4 - are connected downstream of a pair of take-off rollers 9, which may pull off directly from the coil 2.
  • the take-off rollers 9 (due to the vertical belt level at this point) have vertically directed axes, whereas the axes of the feed rollers 21 are horizontal after being rotated by the belt transport and twisting device 20 connected to the take-off mechanism
  • the feed rollers 21 and possibly a vertical (not shown) pair of centering rollers - here for centering the belt 4 in the horizontal plane - are expediently accommodated in a side stand 54 designed in a modular design.
  • These centering rollers are designed analogously to those according to FIG. 5, but of course arranged rotated by 90.
  • the strip-shaped material 4 can then, if necessary, pass through a straightening machine 22 which has the strip to and fro rolls 50, 51, and a loop section (not shown) before entering a processing machine 18, for example a welding machine, here a high-frequency stamping press (which is characterized by the arrangement of compensating masses for the fast punching movement and is accommodated in a soundproof housing 19), which loop section can be replaced by the combined loop and twist section 24 if the straightening machine 22 is omitted.
  • a processing machine 18 for example a welding machine, here a high-frequency stamping press (which is characterized by the arrangement of compensating masses for the fast punching movement and is accommodated in a soundproof housing 19), which loop section can be replaced by the combined loop and twist section 24 if the straightening machine 22 is omitted.
  • a processing machine 18 for example a welding machine, here a high-frequency stamping press (which is characterized by the arrangement of compensating masses for the fast punching movement and is accommodated in a soundproof
  • the coil 2 is arranged on a lifting platform with a supporting platform 3.
  • another form of a vertically displaceable slide can also be provided.
  • a conventional pallet reel with a plurality of coils arranged one above the other, which, for example, belong to the execution of a single order and are therefore processed one after the other.
  • an edge sensor 26 is provided, particularly in this case, expediently for the upper edge of the coil 2.
  • the lifting platform 3 carries a turntable 7, via which the respective coil 2 can be driven in the unwinding direction, and optionally also in the winding direction.
  • Lifting device and unwinding drive form an unwinding station 1, which can be designed in its upper section as a magazine for additional coils 15.
  • the unwinding station has at least two, preferably three to four stands 12 which have latching holes 12a, e.g. in two adjacent vertical rows, as can be found in furniture making. Holding devices 12b can be hung in these latching openings, which support the horizontal cassettes 87 (FIG. 3; see also EP-A-0267357) or documents 72 (FIG. 1.3) of the coils 15 (FIG. 1). As shown in FIG. 1, when applied to the storage of coils, this has the advantage that in the case of coils which are wider than the hole division of the holes 12a, the division of the holding elements 12b need not be changed because - as with the higher coils 15 (with wider band material) can be seen in FIG.
  • the coil is narrower in diameter than its base (this has already been described in EP-A-0 267 357) and can therefore penetrate between the holding elements 12b. In a magazine file, this middle coil 15 then occupies two positions one above the other. This arrangement is of course also advantageous regardless of the centering device described above.
  • stands 12 with a division of notches 12a may also be used to modify and expand an unwinding station. If it is desired to replace a conventional unwinding station, as shown in EP-A-0 267 357 mentioned above, with one with a lifting device, this could also be hung directly into the stand 12 without requiring a separate frame.
  • the lifting device can be designed differently, for example may also have fluid cylinder units. It is essential, however, that it can be raised in more than just two positions.
  • This in turn has the advantage that it counteracts tilting during the vertical movement and thus also ensures that the platform 3 (which can also be formed simply by a rust-like frame) is in a perfect, horizontal position during unwinding. This prevents the searched, centered position from being disturbed by tilting the platform.
  • the lifting device works with elongated tension members, such as cables or (preferably) chains 73, and thus with the aid of an anchoring beam 74 on the holes 12a, or, according to FIG. 3, can be better fixed to the blocks 13 firmly connected to the stands 12 or their connecting walls (not shown).
  • At least one drive motor 8 or 76 is arranged on the platform 3 itself.
  • the motor 8 is provided for driving the turntable 7, while a drive shaft of the lifting device can be driven by the motor 76 via a gear 77 (FIG. 3), so that no further installations are required for the installation of such a lifting device.
  • the gear 77 is expediently designed to be self-locking, for example in the form of a worm gear.
  • An output cable of the edge sensor 26 is connected to the motor 76 and its lifting control, not shown, which is designed similarly to a lift control and, as is known per se in lift controls, can be designed as a mechanical sensor with a roller at the end of a lever in order to actuate a switch .
  • guide rollers 80 engaging on the platform 3 in the peripheral region of the rotary plate 7 are arranged (only two of them are shown in FIG. 4).
  • sliding guides, here in the form of rails 81, are connected to the lifting device, since then the platform 3 carrying the essential elements only needs to be inserted.
  • sliding guides 81 are designed to be as low-friction as possible, given the high weight resting on them.
  • Roller guides such as those used in drawer guides, are conceivable, but it is easier and more stable if they are provided with a sliding coating, in particular made of plastic.
  • a gearbox 89 is also assigned to the rotary drive motor 8, above which a rotary plate 90 with driver pins 71 for the rotary plate 7 is arranged. Since, as mentioned, the band-shaped material 4 is pulled off from the coil with the aid of the take-off rollers 9, the rotary drive 8 is not absolutely necessary for the coil; rather, the tape 4 can also be pulled off the rollers 9, similar to the capstan drive of a tape recorder. However, it is preferred to proceed as described in the simultaneously filed application “Process for controlling the loading of a processing machine with strip material and device therefor” by the same applicant, which is hereby considered to be disclosed.
  • the strip 4 which has now been pulled off the coil 2 in a vertical plane is centered before being rotated into the horizontal position, as shown in FIG. 5.
  • a frame 92 is provided therein, on which two guide columns 93 are expediently fastened in a vertical position.
  • the device shown in FIG. 5 is practically a measuring device which adjusts the height adjustment of the platform 3, so that the band-shaped material 4 is on and in a central plane M. Location is unwound.
  • opposing centering surfaces preferably in the form of centering rollers 6, can be moved towards one another with the aid of the drive 16 until they meet an edge of the belt 4 and give a corresponding signal to the lifting motor 76, which thus moves the platform 3 into that of the centered one Position raises the appropriate height until the other centering surface also abuts the opposite edge of the belt.
  • the drive for the centering rollers 6 can be of any design, for example also fluid. However, it is preferred to use a worm 97 driven by a motor 16, which has a left-hand thread on the one hand and a right-hand thread on the other hand approximately up to the central plane M. In this way, it is ensured without complicated synchronization devices that both rollers 6 can move towards one another by the same amount and at the same speed.
  • two movable supports 98 work together, which have a corresponding internal thread 97 'engaging in the worm 97 at their right end (refer to FIG. 5) and are guided in their movement by the guide columns 93.
  • Each of these carriers 98 carries an axis 95, on which the centering roller 6 is rotatably mounted and thus does not hinder a longitudinal movement of the belt 4 as soon as it rests on the roller.
  • the worm 97 plays the role of a synchronizing device for the movement of the two carriers 98, and it can be understood from this that it can be replaced by any other synchronizing device, for example if each carrier 98 is assigned its own cylinder drive or motor.
  • a sensor traveling on the carrier 98 is connected to each of these centering rollers 6, which sensor is designed here - together with a reflector - as a light barrier 28a. If, therefore, the respective carrier 98 approaches the edge of a belt 4 to be centered, the light barrier is interrupted at the moment when the roller 6 reaches the associated belt edge. Certainly, the reaching of the belt edge could also be determined by measuring a current on the motor 16 which may increase thereupon, but this could lead to undesirable voltages in the belt 4, which is why the arrangement shown is more advantageous.
  • a logic element 94 with AND function reports (in the case of an inductive or capacitive sensor an AND gate, in the case of a photoelectric or pneumatic sensor, as here, a NAND gate) to the control circuit 91 of the motor 76 and to a control circuit 96 for the motor 16 that the centering process has ended and causes both motors to be switched off.
  • a loop strut ke to provide, which is preferably designed as a combined loop and twist section 24 - as shown in Figure 2 - with the loop guides 25. These have an inlet roller basket 48 and an outlet roller basket 48 '.
  • the loop section also has the loop sensor 28 already described with reference to FIG. 2 for the size of the loop. Because the loop section 24, in which the band 4 lies loosely, is connected downstream of the centering device, the free height mobility of this band section is ensured for centering without loss of space or special precautions.
  • lifting drives are also provided for at least one of the loop guides 25 or at least one of the roller baskets 48, 48 ′, here expediently in the form of fluidic cylinder units, such as pneumatic cylinders 35, around at least one of the roller baskets 48, 48 ′, in particular both bring the centering position to be aligned to the center plane M, which is given by the dimensions of the processing machine 18.
  • the circuit according to FIG. 5 has a flip-flop 100 with its inputs at the outputs of the two logic elements 90, 94 or an analog flip-flop whose output Q is connected to a control stage 38 for the two cylinders 35 is.
  • the output Q is switched, i.e. the control stage 38 having a switching valve receives a signal which causes this switching valve to open, whereupon air is supplied to the underside of the cylinders 35.
  • This function presupposes that the sensor 26 is set in such a way that the platform 3 normally remains somewhat below its target position corresponding to the central plane M. Otherwise, the circuit shown must practically be doubled in the sense that corresponding control elements are also available for lowering the lifting device or the roller baskets. It goes without saying that the motor 76 must have reversible rotary devices.
  • the flip-flop 100 is switched to its output Q, i.e. the output Q switches off and the cylinders 35 remain in their respective positions.
  • the use of the stand 12 with its catch system, as explained, is also advantageous without a centering device.
  • the sensor 26 can optionally be replaced by other sensors, such as a television camera to which an edge detection circuit is connected, as has become known for a wide variety of purposes, in particular in the form of contrast detection circuits.
  • the fine centering could also be carried out with the aid of the lifting device if the center plane M is calculated from the determination of the edges (which can also be done in a different way than with a television camera).
  • the special design of the lifting device 3, 73-77, in particular with its support on the circumference of the lifting platform 3, ensures a much more even handling and also saves space than known lifting devices with a central reciprocating piston, because there was always the risk of tilting or a slight skew.
  • a complex synchronization device would be required, which can be dispensed with in the preferred embodiment according to the invention with positively synchronized chains.
  • the carrier 23 can be pivoted out on a hinge 17, so that on the one hand this gives access to the band and the devices assigned to it and on the other hand also to the units mounted on the carrier 23, which advantageously also includes the scissors 14 , is relieved.
  • a conventional unwinding station can be converted cheaply into one according to the invention, since all devices can be preassembled on the carrier 23, which also reduces the delivery times.
  • this also gives access to an advantageously provided band clamping device c on a frame spanning the coil (not shown in FIG. 6) including the rotatable carrier (cf. application WO 90/09945) f with a stationary clamping jaw c1 and a movable clamping jaw c2 guaranteed.
  • a clamping actuation device a associated with this band-clamping device fastened on the frame side is accessible, which is shown in more detail in two positions in FIGS. 6A, 6B.
  • the strap clamping device differs from that described in WO 90/09945 primarily by an extension p of one of the levers of the toggle lever system used.
  • This extension p serves as an actuation approach.
  • the frame f is now pushed into a drawer dr in its plane, but is actuated on the unwinding side by a clamp actuating device a mounted there, care must be taken to ensure that these two devices are correctly coupled to one another.
  • the clamping actuating device a has two claws C11, C12 which are at a distance from one another to form a coupling opening o, the spacing of which from one another is dimensioned in accordance with FIG. 6A such that it not only corresponds to the width of the actuating projection p , but also a tolerance of at least 20%, preferably at least 25%. If the claws C11, C12 and / or the attachment p then have a corresponding width in the direction of insertion (cf. the double arrow 52 in FIG. 6), so that there is a secure overlap in the operating position of the frame f (in FIG. 6 this is the case) secured by the appropriate width of the approach p), so that proper functioning is guaranteed under all circumstances.
  • each chain part 73/1 to 73/4 is attached at one end to a stationary point P above the lifting platform 3 on the stand 12 (FIG. 1).
  • the other end of the chain parts 73/1 to 73/4 is attached to the floor, below the lifting platform 3 at a point P '.
  • the chain parts 73/1 and 73/3 starting from the upper point P
  • pass through the sprocket 83 and a deflection wheel 84 ' which is fastened coaxially with the sprocket 84 on its shaft.
  • the chain parts 73/2 and 73/4 first run over the sprocket 84, starting from the upper point P, in order then to be guided over a deflection wheel 83 'arranged coaxially with the sprocket 83. It goes without saying that the good engagement of the chain links in the sprocket teeth must be ensured, because each chain part, taken on its own, does not ensure a stable position of the lifting platform 3.
  • the drive with the help of the motor 76 via the drive shaft 82 takes place via the chain wheels 83, from where the movement is also transmitted to the chain wheels 84.
  • chain guide as shown in FIG. 8, can also be used.
  • four chain parts 123/1 to 123/4 are used, of which the chain parts with an even end digit and those with an odd end digit are guided in an analogous manner.
  • One end of each of the chain parts 123/1 to 123/4 is attached to the floor point P ', the other directly to the lifting platform 3.
  • the chain parts 123/1 and 123/3 starting from the attachment point on the lifting platform 3, first run upwards and then down over the deflection wheel 85.
  • a first deflection wheel 83 ' is attached to the lifting platform 3, via which the chain parts 123/1 and 123/3 run in an almost horizontal direction to a further deflection wheel 84' arranged coaxially with the sprocket 84, and from there down to point P '.
  • the chain parts 123/2 and 123/4 starting from their attachment point on the lifting platform 3, initially run upwards to a stationary deflection wheel 86, from where they are again guided downwards to the chain wheel 84. After wrapping it around 90, the respective chain part 123/2 or 123/4 then runs approximately horizontally to the driving sprocket 83, and from there down to point P '.
  • This latter variant has the advantages of a block and tackle and is therefore preferred.
  • FIG. 9 a satisfactory solution can now be found by placing the entire unwinding station 101 in a closed housing ho formed by walls w, which can be closed, for example, by a protective grille-like cover 61.
  • the arrangement is preferably such that the take-off rollers 9 and / or the centering rollers 6, possibly together with the scissors 14, are attached on one side of the housing ho, expediently in the carrier 23 mentioned, whereas on the opposite side one by at least one Cover, like the two doors d shown here, is provided with a closable loading opening 30, whereby the handling is improved (compared to the loading shown in the previous figures at right angles to the take-off rollers 9).
  • this design enables such unwinding stations 101 to be arranged next to one another in a row, at most interrupted by laterally mounted magazines, so that all unwinding stations 101 can be loaded from a common loading aisle, preferably via controlled handling devices, which simplifies the control of these devices.
  • 9 shows the application of the unwinding station 101 for known pallet reels with several coils 2 one above the other, but due to the modular construction with easily releasably attachable units, it goes without saying that a conversion to cassette operation with the frame f mentioned is easily possible.
