Definitions

  • the invention relates to a method according to the preamble of claim 1 and to an apparatus for performing this method according to the preamble of claim 6.
  • Such a method is known both from FR-A-2 340 149 and from EP-A-0 267 357.
  • the first case involves feeding a welding machine, and in the second case a punching machine.
  • the tape was manually pulled off the coil at the beginning of the operation and, likewise manually, passed through a twisting section, with a hand lever being provided for twisting a pair of guide rollers.
  • a pair of scissors and a welding machine by means of which successive belt ends could be welded to one another in order to avoid re-threading into the processing machine. Only then did a pair of driven feed rollers follow, which subsequently enabled the belt to be forwarded automatically.
  • the invention has for its object to make the loading process faster and safer and to enable a simple automatic system, which at least largely eliminates manual operation. This goal is achieved by the characterizing features of claim 1 and claim 6.
  • the device according to the invention for carrying out the method according to the invention is characterized by the features of claim 6.
  • the features of claim 9 are preferably provided. Its mandatory features are also advantageous regardless of the method and device according to the invention, because this ensures that the tool in the processing machine can be quickly removed, especially in the event of malfunctions or for the purpose of installing another tool, and that after the tape has been cut off, no further run-down period may be required for the processing machine to process a tape residue. Such a tape residue is caused by the ab in the area of the machine cutting avoided. The end of processing and a new loading will be accelerated if the optional features are also provided.
  • a roll-off station 1 is provided for a coil 2 mounted on a lifting device 3.
  • the details of the lifting device 3 and its control can be found in the patent application "Method for loading a processing machine with a fine centering step and device therefor" from the same applicant on the same day, the content of which is hereby deemed to be disclosed.
  • band-shaped material 4 is, according to the coil axis 5, in a vertical plane and is first guided by guide rollers 6 on both edges when it is unrolled by driving a rotary plate 7 provided at the unwind station 1 with the help of a motor 8 .
  • a pair of take-off rollers 9 which lie one behind the other parallel to the plane of the drawing.
  • a drive motor 10 on a bracket 11, which is fastened to a stand 12, is assigned to this pair of pull-off rollers 9.
  • the pull-off roller pair 9 is thus in the immediate vicinity of the coil 2 or in the circumferential region of the coil, so that when a drive 8 provided for it, which will be described later, is actuated, the automatic transfer of the beginning of the tape from the coil 2 to the pull-off roller pair 9 is also ensured in a simple manner is, whereby the band-shaped material 4 can be automatically threaded.
  • a device carrier 23 which is permanently attached either to a free-standing pallet reel or to the stand 12 of the coil storage tower (magazine unit), in which a unit 6 for fine-centering the belt 4 on its neutral axis M, but possibly also the mentioned pair of pull rollers 9 and / or a pair of scissors 14 for severing the tape 4, each designed as a modular unit.
  • a pull-off and twisting device 20 which is preferably accommodated in a closed housing, which is similar to that in EP-A 267 357 shown device (see there Fig. 9) can be formed. If necessary, a height adjustment (or a lateral adjustment) together with an associated motor or fluid drive can also be provided for this pull-off and twisting device 20, as will become apparent from the later explanation. In general, however, a rigid arrangement of this device 20 is sufficient. As can be seen from FIG.
  • this rotating device 20 requires at least one drive for pulling off the band 4 under tension, specifically from the take-off rollers 9 to a pair of feed rollers 21 in front of a straightening machine 22 (FIG. 1) or directly into the processing machine 18 (FIG. 2) if the straightening machine 22 is dispensed with.
  • the feed roller pair 21 is expediently accommodated in its own side stand 54, which may be designed as a modular unit.
  • the band 4 can be turned to the left or to the right, which is important in particularly stored cases, for example if the cutting bit is directed towards a certain side, wherein it saves you from rewinding.
  • the speed of the coil 2, which may be driven by the motor 8 must always be greater in order to keep the take-off speed of the strip-shaped material 4 constant.
  • One possibility would be to use a button 26 to sense the circumference of the coil 2 and to control the speed of the motor 8 accordingly.
  • the button 26 also serves other purposes, which are described in the simultaneously filed patent application by the same applicant.
  • a further belt take-off mechanism in the form of the take-off rollers 9 already mentioned with reference to FIG. 1 is provided.
  • the revolutions of the motor 10 driving it are regulated by a control stage 27 in the sense of keeping the rotational speed constant, so that ultimately strip material 4 is fed uniformly to the straightening machine 22 or processing machine 18.
  • the drive motor 8 thus conveys the belt directly to the next constant drive, without interposing a loop that could have a compensating effect, although this would also be possible within the scope of the present application.
  • control stage 27 is assigned a TARGET value transmitter 29, with the aid of which the speed of the motor 10 can be set. If one assumes that 6 further tape guiding devices are provided in the area of the centering rollers, for example the coil is stored in a cassette, e.g. As described in EP-A 267 357, the unrolling of the coil for loading the straightening machine 22 or the processing machine 18 can proceed completely automatically from the placement of the coil 2 on the turntable 7.
  • a sensor is connected to the motor 10, the output signal of which is fed to a control stage 31 for the motor 8.
  • this can be a current sensor 30 for at least one power-determining parameter, such as voltage or current consumption.
  • a conventional sensor will therefore be preferred for such cases.
  • a program generator 32 e.g. a microprocessor is provided, of which, as in the following figures, only those connections are shown, which are necessary for understanding the respective figure.
  • This programmer 32 which may also include other of the stages shown, such as parts of the control stages 27 and 31, has two inputs, each of which leads via a switch S1 and S2.
  • the switch S1 switches the program on after the respective coil 2 has been placed on the turntable 7 to initiate a loading program, and the switch S2 switches on an “end of the loading” program.
  • the switch S1 is actuated, the two control stages 27 and 31 are activated and the motors 8 and 10 start to run, the motor 8 being regulated as a function of the sensor signal from the sensor 30.
  • the motor 8 is therefore expediently a direct current or a synchronous motor.
  • the tape transport and twisting device has a gripping mechanism which is connected to a displacement drive in order to pull the tape 4 from the area of the take-off rollers 9 to the feed rollers 21.
  • a 90 ° turn which can be done by a cam drive (i.e. without its own motor) or - as preferred - with a separate electric motor.
  • the twisting device 20 is assigned two control stages 33, 34 (FIG. 2), of which, for example, the control stage 33 controls the, in particular fluid, but possibly also electrical, displacement drive, and the control stage 34 controls the twisting drive.
  • a straightening machine 22 is provided in the system (FIG. 1), the band-shaped material 4 is rotated, but is introduced into the latter without first forming a loop.
  • upper and lower rollers 50, 51 are provided in the usual way, between which the band 4 is bent back and forth (with ever decreasing wrap angles around the rollers 50, 51) in order to compensate for internal stresses.
  • a control stage (not shown) of the drive 52 of the rollers 50, 51 is advantageously connected to the synchronization stage 45 (FIG. 2) for the purpose of synchronization with the motors 10 (the take-off rollers 9) and 40 (the feed rollers 21).
  • the belt transport and twisting device 20 is to take action without a straightening machine 22, it is designed to be open towards the bottom in order to form a To enable loop 24.
  • the twisting of the band 4 and the formation of loops then take place in a combined loop-twisting section.
  • the decision as to whether a system is operated with or without a combined loop twist section depends on the type and dimension of the strip-shaped material 4 to be processed: if the strip is thin and / or narrow, the preferred combined loop Can be driven because no straightening machine is required; if the strips are wide and / or stiff, the twisting distance is straight (as in FIG. 1) and a straightening machine 22 is required.
  • a cylinder unit 35 is assigned to two roller baskets 25 designed as a guide device in order to control the lowering of the belt guides 25 at the moment the take-off roller pair 9 is taken over by the take-off roller pair 9.
  • a signal is sent to the programmer via line 36, which in turn via line 37 sends a start signal to a cylinder control stage 38 for lowering the tape guides 25 releases.
  • any other sensor can also be provided if, for example, the tape 4 is to be taken over later or for other reasons the arrangement of an optical, inductive or capacitive sensor ( pneumatic would also be conceivable) is desired.
  • the speed of the take-off rollers 9 is greater than that of the feed rollers 21, i.e. it is best to switch the latter off completely, keeping the band 4 clamped between them.
  • These two feed rollers 21 are pressed against each other, for example, by an immersion magnet 41 (or any other device), which at the beginning of the program (switch S1), but better only when the belt 4 arrives at the take-off rollers 9 (sensor 30), but possibly also only after reaching a predetermined position of the gripping and rotating drive 20 by the programmer 32 and by an output line 42 was energized.
  • the drive 40 for the feed rollers 21 is switched on again in order to convey the belt 4 into the processing machine 18 (FIG. 2).
  • a corresponding command is issued by the programmer 32 via a line to the motor control stage 39, a synchronization circuit 45 ensuring that the two motors 10 and 40 are synchronized.
  • the mere frictional drive is usually subject to slip due to the rollers 9 or 21. It is therefore necessary to maintain the loop size that the peripheral speed of the feed rollers 21 is slightly greater than that of the take-off rollers 9.
  • the signal from the loop monitor 28 can be used to trigger a faster speed of the motor 40 when the light barrier is covered even more by the programmer.
  • the synchronization device 45 could also be designed in such a way that it runs the motor 40, for example at a speed which is 2% higher, that is to say it only "quasi-synchronized" to a certain extent.
  • a centering subroutine can be initiated if the system shown is provided with a height adjustment device, as described in the parallel application mentioned several times.
  • a command to a control stage 47 for triggering the centering subroutine is triggered via the line 46, the two centering rollers 6 (FIG. 1) being triggered by the motor 16 (FIG. 2) is moved against the belt edges of the belt 4 in order to bring it to a central plane M (the so-called neutral axis of the belt 4) corresponding to the machine 18 (FIG. 2).
  • the synchronization circuit 45 ensures the synchronized operation of the motors 10 and 40, it being expedient if the synchronization stage 45 with the programmer 32 via a line 49 is connected to also deactivate this stage when the drive of the feed rollers 21 is switched off.
  • the band-shaped material leaves the straightening machine 22, it runs through a simple loop section, not shown here, which is designed without twisting the band 4, in which essentially the same subroutine as that described with the aid of the loop section 24 runs to form the loop, and enters the loop section Processing machine 18 a; this is e.g. a - because of the high punching frequencies surrounded by a sound-absorbing housing 19 - high-frequency punching machine.
  • a pull-in roller pair 55 (FIG. 3) arranged on the input side of the insulating housing 19 can be provided, to which the band 4 is fed following the loop program; the loop can also be formed in any way.
  • the feed rollers 55 can also be used to withdraw the remaining tape from the processing machine 18 at the end of a processing operation.
  • the feed rollers 21 can take over the task of the pair of feed rollers 55.
  • the feed rollers 55 can also be pressed against one another by means of a drive, such as the magnet 41 (see FIG. 2), in order to be able to equip the system either with or without a straightening machine 22 and in the latter case to be able to switch off the feed rollers 55.
  • a feed roller motor 56 is provided, the control stage 57 of which is controlled or regulated synchronously by the programmer 32 or the synchronization stage 45.
  • the control stage 57 can therefore also be linked to a load sensor in order to notify the programmer 32 of the arrival of the tape 4 at the feed rollers 55. A different type of sensor can also do this.
  • the magnet 41 (FIG. 2) is then de-energized again, so that the upper feed roller 21 lifts off from the lower one under the action of a tension spring 58 or the feed rollers 21 are deactivated.
  • the tape 4 is now processed in the usual way by the punching machine 18 until either a step counter installed at 59 indicates that a previously set number of punched parts has been reached and (instead of the switch S2 in FIG. 2) an "end" signal to the Provides programmer 32, or the switch S2 is operated by hand.
  • the "end" signal by the counter or by hand starts a special subroutine of the programmer 32.
  • a cutting tool 62, 63 can be provided on the machine 18 itself if, for whatever reason, this processing should not be possible. These cutting tools 62, 63 are then provided directly on the machine 18 and come into operation when the strip end cut off by the scissors 14 (at the end of a processing job) is just between the feed rollers 55 (or 21 if no straightening machine 22 is provided). has arrived. The feed rollers 55 and 21 then pull back the short remainder of the strip so that the next start of the strip can also be fed automatically again.
  • the cutting tool 62, 63 in the processing machine 18 can also function, if a malfunction has occurred, or for particularly valuable, eg silver-coated tapes; then the band 4 can be pulled back over the entire loop section 24.
  • FIG. 3 shows schematically two scissor parts 62, 63.
  • the scissor part 62 fastened to the upper tool 60 is rigidly fastened, for example, whereas the other scissor part 63 from a rest position, in which it lies in the inactive position and the band 4 is unimpeded to the can pass both parts 62, 63 past or between them, can be moved into a working position in order to cooperate with the scissor part 62 for cutting off the band 4.
  • a drive magnet 64 (or any other suitable, possibly also fluidic drive) is provided which, together with the other parts for the scissor part 63, is expediently arranged as a structural unit on a mounting plate 65 in order to be subsequently attached to any tool 61 to be able to.
  • the scissor part 62 (which may also be designed differently and, if desired, also movable) is attached to the upper tool part 60.
  • the program generator 32 provides for a brief excitation of the magnet 64 in order to cut off the tape 4, so that only a tape residue remains in the tool itself.
  • the programmer gives the command to the motor control stages to reverse the direction of rotation, so that the entire remaining tape is conveyed back to the coil 2 and rewound again.
  • the rollers 50, 51 of the straightening machine can be moved apart (drive for this is not shown) in order to facilitate rewinding.
  • the scissors 14 are also expediently provided in addition to the scissors 62, 63 and at the same time receive the command from the programmer 32 to cut the tape with the latter. While the take-off rollers 9 can be stopped at most, the upstream drives, i.e. the motor 56 (if the feed rollers 55 are not omitted and are replaced by the feed rollers 21), the motor 52 (if the straightener is not omitted or the rollers 50, 51 are moved apart), but in any case the motor 40, the command to feed back the Volume 4.
  • the upstream drives i.e. the motor 56 (if the feed rollers 55 are not omitted and are replaced by the feed rollers 21)
  • the motor 52 if the straightener is not omitted or the rollers 50, 51 are moved apart
  • the motor 40 the command to feed back the Volume 4.
  • the scissors 14 is from the programmer 32 via a control stage 66 for a schematically indicated, for example Fluidic, but possibly also electromotive (spindle drive) scissors drive 67 (Fig.2) can be controlled.
  • a control stage 66 for a schematically indicated, for example Fluidic, but possibly also electromotive (spindle drive) scissors drive 67 (Fig.2) can be controlled.
  • the scissors 62, 63 can only be activated for a short time, since after an excitation current has been removed from the magnets 64, a return spring 68 ensures that the scissors part 63 returns to its rest position shown in full lines.
  • a spiral shape of part 63 facilitates cutting, as such curve shapes (also other arches) are often found in scissors.
  • a collecting trough 69 (FIG. 2) is provided, which can be pivoted, for example, about an axis 70 in order to unload the remainder of the belt onto a conveyor (not shown).
  • a drive e.g. in the form of a plunger magnet 71, which, after completion of the return of the belt 4 into the trough, expediently after a sufficient time determined by the clock generator of the programmer 32, tilts the trough and empties the remaining tape onto the conveyor mentioned or into a waste container .
  • the system is now ready to carry out a new loading program.
  • the combination of the loop section 24 with the twisting device 20 brings particular advantages. Because after the band-shaped material 4 has been rotated by the band transport and twisting device 20 and transferred to the pair of feed rollers 21 or 55, the loop section 24, as can be seen from FIGS. 1 and 2, ensures this automatically and, above all, without tension that the band 4 entering the loop section 24 in the vertical plane is rotated again and again by 90 about its longitudinal band axis. Of course, this effect also arises in the case of a tensioned belt, but the twisting causes a different pressure of the edges on the respective pair of rollers, i.e. one edge will act more on one roll, the other edge will press on the other roll, which can result in different slip ratios and thus internal tensions in the belt.
