Definitions

  • the invention relates to the general field of high-speed packaging machines. Such machines are used for example to perform at high speed the individual packaging of chocolate plates or other products presented in a similar manner.
  • the packaging of an article requires the execution of a relatively complex series of positioning, folding and gluing operations, carried out automatically.
  • a machine of this kind receives on the one hand a succession of articles to be packaged, such as chocolate plates, and on the other hand a succession of coupons each of which is used by the machine to package an article.
  • the succession of coupons is in principle provided by a printing house in the form of a continuous strip repeatedly comprising separation marks as well as inscriptions or drawings for the presentation of the article.
  • the strip is supplied wound in the form of a reel.
  • a device connects the reserve reel to the strip without interrupting the operation of the machine.
  • a device is well known to those skilled in the art under the name of "splicer". As soon as the splicer has started the second coil, the first, which is exhausted, is replaced by a full coil and constitutes the reserve coil. The replacement of the coils therefore requires no interruption.
  • the machine comprises a cutting station and, for the cutting to be correct, it includes a means of detecting marks upstream of the cutting station and a means of correcting the advance of the strip, so that the cutting conforms to the benchmarks with a given tolerance.
  • a main drive shaft drives all the packaging members as well as the rollers which control the advance of the strip, which is often a strip of paper, upstream of the cutting station.
  • the strip may be made of another material such as for example cellophane or a synthetic material.
  • the tape supplied may have a local defect in the marks, for example due to an incorrect connection of two ends of the tape. Also in such a case, it is necessary to stop the machine when the fault exceeds said amplitude.
  • the machine must be adjusted according to the length of the coupon.
  • the tolerance of this adjustment must obviously be less than the correction margin, which is small, so that the adjustment is delicate.
  • German document DE-A-2,203,383 discloses an arrangement which also has certain drawbacks: the correction is carried out in one direction only and restrictions are imposed with regard to the printing of paper.
  • the correction is carried out by a device comprising a differential and an electromagnetic brake combined with an electromagnetic clutch which are organs subject to significant wear and the accuracy achieved is low.
  • German document DE-A-2 605 602 discloses an arrangement with a discontinuous advance of labels intended to be applied to products moving continuously.
  • the discontinuous advance of the labels is obtained by controlling a clutch placed in the drive of the strip carrying the labels.
  • the clutch is subject to wear and the discontinuous operation of the advance of the labels severely limits the rate.
  • German patent DE-C-1,461,898, German patent application DE-A-2,524,365 and American patents 2,611,224 and 2,636,731 also describe arrangements of the same kind which have most of the faults reported in About the aforementioned Swiss Patent 305,288; in particular, the correction is made in one direction only, restrictions are imposed on the printing of the paper and the paper advance is intermittent.
  • the present invention aims to remedy these drawbacks.
  • the problem of the invention is resolved by the features indicated in claim 1 for the method and by the features of claim 5 for the device.
  • Fig. 1 there is shown schematically a packaging machine supplied, on the one hand, with a succession of articles to be packaged 61 and, on the other hand, with a strip of paper 70 supplied continuously by a splicer 50.
  • the splicer comprises a reel in the course of unwinding 51 and a reserve reel, full, 52.
  • the strips 53, 54 issuing from the respective reels pass through a series of rollers 55 and end at a connection station 58.
  • the connection station connects, by gluing, the end of the strip 54 to the end of the strip 53, without interrupting the running.
  • the sudden start of the strip 54 is absorbed by a displacement of some of the rollers 56, mounted for this purpose on articulated arms (not shown).
  • the splicer 50 continuously supplies a strip 70 which passes under a detector 13, which is driven by the upper 5 and lower 6 feed rollers, and which is cut into coupons by a rotating blade 9 cooperating with a fixed blade 10.
  • the coupons are used in machine 60 for the individual packaging of articles 61.
  • the strip 70 comprising a series of coupons 72 separated by markers 71.
  • the coupons also include other signs and marks, not shown.
  • the marks 71 pass under a photoelectric detector of marks 13.
  • the strip is driven by the upper 5 and lower 6 feed rollers, mechanically connected to rotate in synchronism.
  • the lower roller is driven by a direct current motor 1 via a mechanical transmission device 200 introducing a certain reduction factor between the output axis of the motor 1 and the axis of the roller 210.
  • a pulley 203 wedged on the axis of the motor 1 is connected by belt to a pulley 204 integral in rotation with a pulley 205, itself driving by belt a pulley 206 wedged on the axis of the lower roller 6.
  • the motor 1 is associated with a tachometric dynamo 2 used for an adjustment loop for the control of the motor 1.
  • a pulse generator formed by a wheel 32 bearing radial marks and d 'an associated photoelectric detector 33.
  • the strip 70 after having passed between the feed rollers 5, 6, passes between a rotating blade 9 and a fixed blade 10 which, periodically, cut the strip to separate the coupons.
  • the just separated coupon 73 is then used by the machine for packaging an article.
  • the rotating blade 9 is rotated by the axis 8.
  • the axis 8 is linked to the mechanical members of the packaging machine, in particular to the members of the packing station (not shown).
  • the axis 8 carries a pulse generator formed by a wheel 11 carrying radial slots and a photoelectric sensor 14.
  • the same axis 8 also carries a synchronization signal generator formed by a wheel 12 carrying a notch and associated photoelectric sensor 15.
  • the circuits of Fig. 3 have the function of controlling the motor 1 which drives the paper feed rollers 5, 6 as a function of different signals.
  • the photoelectric detector 14 produces pulses whose frequency is proportional to the speed of rotation of the axis 8, which carries the rotating blade 9 and which is kinematically linked to the main mechanical organs of the packaging machine and in particular to the station d packaging (not shown).
  • the signal produced by this detector 14 therefore constitutes a speed reference, signal REFVIT2, indicating the operating speed of the cutting and packaging stations.
  • This signal leads to a frequency-voltage conversion circuit 140 which delivers at its output 143 a signal whose voltage is proportional to the frequency of REFVIT2.
  • the circuit 140 includes a scale adjustment 141 by rheostat, which makes it possible to choose the length of the cut without correction.
  • the voltage signal supplied at output 143 constitutes a basic speed setpoint for a block 120 for controlling the motor 1, which drives the paper feed rollers 5, 6.
  • An action on the rheostat 141, all other parameters being preserved constant, will therefore have the effect of modifying the basic speed setpoint, therefore a modification of the paper feed speed, and consequently a modification of the cutting length.
  • the circuit 140 also has an adjustment rheostat (offset) 142.
  • the control block 120 is of the “four-quadrant regulator” type and it uses, for the control of the motor 1, an adjustment loop comprising the tachometric dynamo 2.
  • the control block 120 admits two input setpoint quantities, from which to see the first, which is the basic speed setpoint for line 143. If the control unit 120 operates on the basis of this single signal, there is simply a proportional slaving of the paper advance at the rate of the machine, that is to say of the axis 8 kinematically linked to the cutting and packaging stations. This is, roughly speaking, what happens when the paper strip 70 is correctly in phase with the operating cycle of the machine.
  • the other circuits of FIG. 3 allow the establishment of a correction signal when there is a phase shift of the paper strip 70.
  • the photoelectric detector 33 produces pulses whose frequency is proportional to the speed of rotation of motor 1 and constitutes a speed reference, signal REFVIT1.
  • the photoelectric detector 15 supplies a pulse at each revolution of the rotating blade 9, that is to say at each cycle of the machine. It therefore gives a phase reference for the operation of the cutting and packaging stations, signal SYNCHR.
  • the photoelectric detector 13 produces a pulse during the passage of a mark 71 of the strip 70.
  • a logic control circuit 100 comprising as main component a logic processor, for example a microprocessor "INTEL 8085 •.
  • This control circuit 100 is provided with a quartz 101 and can supply a clock signal at 3 MHz on a line 102.
  • the logic control circuit 100 is connected to an eight-bit digital selector 108 constituting an input device . This selector is used to digitally choose the value of the cutting length between 0 and 255 arbitrary units.
  • the control circuit 100 is also connected to a display device 107, for example with light-emitting diodes (LED), which constitutes an output device for displaying, for example, the correction values.
  • LED light-emitting diodes
  • the logic control circuit 100 drives a fast processor 110, for example a CD 1802 D microprocessor known as "COSMAC from the firm R.C.A.
  • the logic control circuit 100 provides the rapid microprocessor with a quantity which is the value of the correction, in 7 bits, as well as the direction, which requires 1 bit; it also provides LOAD and START pulses and the clock signal.
  • the fast processor 110 sends on line 130 a train of pulses whose frequency is converted into voltage by the conversion circuit 111.
  • the circuit 111 has an adjustment scale by rheostat 141 and an adjustment rheostat (offset) 113.
  • the output of the converter 111 is inverted by the inverting amplifier 114 which also has an adjustment rheostat (offset) 115.
  • An electronic switch 116 chooses, for the output line 118, either the inverted signal leaving the inverting amplifier 114, or the non-inverted signal leaving directly from the conversion circuit 111.
  • the position of the switch 116 is controlled by the sense bit, on line 117.
  • the voltage supplied on line 118 constitutes a correction setpoint signal for control unit 120.
  • Fig. 4 illustrates the operation of the circuits in Fig. 3. It shows, by a time diagram, how a reading signal of a reference 71 is identified, how a possible phase shift of the paper strip 70 is evaluated with respect to the operation of the packaging machine; in case A, the band has a delay and in case B, the band has an advance.
  • the REFVIT signal is a succession of pulses produced by the pulse generator comprising the detector 33 and the wheel 32, fixed on the axis 8 of the motor 1 for driving the feed rollers 5, 6.
  • the signal SYNCHR is produced by the detector 15 associated with the notched wheel 12, which gives a pulse at each revolution of the axis 8, that is to say at each cycle of the machine. Note, in Fig. 4, that a SYNCHR cycle or period is equivalent to 72 pulses of REFVIT. In reality a machine cycle is equivalent to a higher number of pulses, for example 1000 pulses, but the number of 72 has been chosen to illustrate the example. Similarly, the other values are relatively arbitrary and have only an example value,
  • the control circuit 100 When a reference mark 71 passes under the detector 13, the latter produces the signal LECTREP which has the form of a rectangular pulse, of a certain length, for example 9 small periods of the signal REFVIT.
  • the control circuit 100 creates a MIN pulse starting with the initial edge of LECTREP; this MIN pulse representing the minimum duration that LECTREP must have to be admitted.
  • the control circuit 100 creates a pulse TOL which represents the interval between the minimum duration and the maximum duration that LECTREP must have to be admitted: it is therefore the tolerance interval for LECTREP.
  • LECTREP is admitted since its final flank falls in the middle of TOL.
  • MIN lasts 7 small periods
  • TOL lasts 4 small periods
  • the control circuit 100 counts the pulses from the end of LECTREP, as illustrated by the signal ERR. This count ends when the SYNCHR signal appears. In the case of Fig.4A, the totalized number of pulses is equal to 60.
  • LECTREP has an advance of 60 pulses compared to the following SYNCHR signal. But it is more rational to consider that it presents rather a delay compared to the preceding SYNCHR signal.
  • the logical choice is to compare the deviation found with half the duration of the machine cycle. If the deviation found is greater than the half-duration of the cycle, then the error is worth the duration of the cycle minus the deviation and it is a delay. This is the case here: and the error is worth:
  • the direction of the correction is coded by the control circuit 100 in the direction bit and the value of the correction is supplied to the fast processor in the form of a binary number of 7 bits.
  • the fast processor uses this data to establish a train of pulses according to appropriate programs which take into account, in particular, the desired pace of the correction, the acceleration and the desired deceleration, in a word: correction kinematics. These pulses are supplied on line 130 and used as already described above to control the motor 1.
  • An error means that the marks and inscriptions on the coupon are offset and that the coupon is not cut in the right place.
  • the coupon is then still used in the packing station, but the corresponding article is eliminated because its presentation is unacceptable.
  • the control circuit which has detected the error, sends a signal to the packing station for automatic disposal of the article.
  • the admissible correction for the paper advance has a maximum. Correcting an error means that the next coupon will be cut shorter (or longer). However, the length of the coupon must remain acceptable for the packing station, since an interruption must absolutely be avoided. For example, the maximum correction value, ⁇ 15 mm, will be adopted. If an error greater than these 15 mm occurs, for example an error of 75 mm, this will simply have the effect that the error will be caught up in several cycles, here in five cycles, with the elimination of five articles. Disposing of a few items is obviously better than stopping the machine.
  • ⁇ 15 mm for the maximum correction value is taken here as an example. This value is imposed by the packing station and could be changed. If the packing station can accommodate coupons with a greater difference, for example ⁇ 50 mm, and continue to operate without jamming or snagging (even if this means eliminating unacceptable items), this latter value can then be taken ⁇ 50 mm as the maximum correction value.
  • the distance between the detector 13 and the blades 5, 6 has been assumed to be a multiple of said length. If the latter changes, the detector 13 should be offset, which can be mounted on a rail. But we can, alternatively, angularly shift the notched wheel 12 which is used to create the SYNCHR signal.
  • An advanced solution consists in leaving the detector 13 and the notched wheel unchanged and in acting only at the level of the software (software) of the logic control processor. Indeed, all the necessary information is provided by the selector 108; it is easy for a person skilled in the art based on the present description to program the processor accordingly.
  • Changing the format also involves changing the paper feed speed. If the coupons are for example longer, this speed must be greater for a given rate of the machine. It is therefore necessary to adjust the speed of the rollers by adjusting the rheostat 141 accordingly. As indicated above, this rheostat allows the cutting length to be chosen without correction. The latter setting is not critical. A residual difference, for example of ⁇ 5 mm, is not very troublesome in the case considered where the maximum correction is equal to ⁇ 15 mm; the difference is automatically compensated.
  • Figs. 5 to 7 illustrate an embodiment in which the paper advance is mechanically coupled to the rest of the packaging machine, in particular at the cutting and packaging stations, by by means of a differential which makes it possible to introduce the appropriate corrections, under the control of electronic circuits.
  • the axis 16 is kinematically linked to various mechanical components of the packaging machine, in particular to the components of the packaging station (not shown).
  • the axis 16 can be the main drive shaft of the machine. This shaft 16 drives the axis 8 of the rotating blade, via the pulley 19, the belt 18 and the pulley 17 fixed on the axis 8.
  • the axis 16 also drives an axis 23 by the intermediate a pulley 20, a belt 21 and a pulley 22 wedged on said axis 23. This axis 23 rotates inside a hollow shaft 35.
  • the axis 23 and the hollow shaft 35 are connected by a differential 37.
  • the hollow shaft drives an external ring 45 and the axis 23 drives an internal sun gear 42.
  • the planet pinions 41 of a planet carrier ring 40 are engaged.
  • the planet carrier ring 40 meshes with a pinion 36 fixed on the axis of a stepping motor 51.
  • the hollow shaft 35 drives an axis 30 by means of a pulley 28, a belt 29 and a pulley 31 fixed on the axis 30.
  • the axis 30 drives a pulse generator comprising a wheel 32 bearing radial marks and a photoelectric detector 33.
  • the hollow shaft 35 also drives the lower feed roller 6 by means of a pulley 24, a belt 25 and a pulley 26 fixed on the axis of the lower roller 6.
  • the wheel 32 of the pulse generator and the paper feed rollers 5 and 6 are kinematically linked.
  • the differential behaves like a gear introducing a certain reduction factor between the axis 23, considered as the motor axis, and the hollow shaft 35, which is the driven shaft.
  • the hollow shaft finally drives the rollers 5 and 6 and that, for its part, the axis 23 is mechanically linked to the axis 16 of the machine, there would then be a mechanical transmission with a given reduction factor between the axis 16 of the machine and the paper feed rollers 5, 6. This is roughly what happens when the paper strip 70 is correctly in phase with respect to the operating cycle of the machine.
  • the motor 51 and the circuits of FIG. 7 come into play when there is a phase shift of the paper strip 70.
  • the circuits of Fig. 7 have the function of controlling the stepping motor 51 which introduces, through the differential 37, a correction in the drive of the paper feed rollers 5, 6, as a function of different signals.
  • the photoelectric detector 14 produces pulses whose frequency is proportional to the speed of rotation of the axis 8. This signal does not in principle play an essential role in this embodiment. It can optionally drive the splicer 50. It can also be used to modify the clock signal received by the fast processor 110, via a circuit 105. This allows for example to perform tests at low speed .
  • the fast processor may be the CD 1802 D "COSMAC from the firm R.C.A. ; such a processor can operate at a very low rate, and even step by step, with a clock signal which can have an arbitrarily low frequency and, ultimately, zero.
  • the acceleration and deceleration predicted by a program, for a given kinematics, will then be proportionally reduced, in the simplest way, which makes certain tests easy.

  • the processor 110 optionally includes a special output 133 for a signal indicating whether the motor 51 should operate or not. If the motor 51 is not to run, it is preferable to reduce its quiescent current to avoid excessive consumption and undesirable overheating.

  • the new length must be transferred to the selector 108, in a manner similar to that which is provided for the machine of FIGS. 2 and 3.
  • the paper feed speed still needs to be changed.
  • the motor 51 only serves to introduce corrections, it is necessary to change the mechanical ratio which exists between the axis 8 and the rollers 5, 6 when the motor 51 is stationary. This ratio can be changed by replacing, for example, the wheel 26 and its belt 25.
