Definitions

  • the present invention relates to a device for supplying packaging material to a packaging machine, comprising two reels each carrying a reel of packaging material in the form of a strip, these reels being operated alternately to ensure a continuous supply. of the machine, a device for driving the packaging material, a device for detecting the end of the strip, and a device for automatically assembling the end of the strip of packaging material from the reel in service and the start of the strip coming from the next reel, this device comprising a press for applying the two ends of the strips to each other and a control device for this press, arranged to receive an end of strip detection signal by the end of strip detection, and for controlling said press.
  • the tension exerted on the packaging material at the time of startup or each time it is restarted in a machine operating intermittently, is very large, which prevents the use of packaging material of small thickness.
  • the use of aluminum film with a thickness of 9 to 10 w, the tensile strength of which is insufficient to be subjected to such tensions, is prohibited in these machines.
  • the present invention proposes to remedy this drawback in particular, by providing a device for supplying a packaging machine, with a packaging material in the form of very thin strips, this supply being made semi-automatically. with a maximum of precision.
  • the device according to the invention is characterized in that it comprises two drive servomotors arranged to independently drive the two reels, two independent coding and detection devices arranged to supply a coding signal depending on the instantaneous diameter of the reels, two independent speed detection devices respectively coupled to said servo motors and a detection device coupled to two rollers for driving the strip of packaging material, these two speed detection devices and this detection device coupled to the rollers being arranged respectively to supply a signal which is a function of the speed of rotation of the reels and of the speed of travel of the strip, and a control circuit arranged to alternately adjust the speed of one or the other of the servo drive motors as a function of the instantaneous diameter of the driven reel and the linear speed of travel of the b ande.
  • the method according to the invention in which the reels are put into service alternately to ensure a continuous supply of the machine, in which the end of the strip is detected and the end of the strip of packaging material is assembled the reel in service and the start of the strip coming from the following reel is characterized in that the two reels are driven alternately and independently of one another by means of two independent servo-motors, in that the the instantaneous diameter of the reel is detected and a signal corresponding to this instantaneous diameter is transmitted to a control circuit, in that the speed of rotation of the reel in service is detected to transmit a signal to the control circuit reel speed setting instruction, in that the tape running speed is detected to transmit a corresponding signal to the control circuit, and in that the control circuit transmits to the drive servo-motor control signal, a function of the speed of travel of the strip and the instantaneous diameter of the reel.
  • the device as shown in FIG. 1 comprises a reel 1, the spindle 2 of which supports a reel 3 of partially opened packaging material, for example aluminum film 9 to 10 ⁇ thick.
  • the spindle 2 of the reel is driven by a drive motor 4 having excellent acceleration and braking characteristics.
  • the packaging material 5 in the form of a strip forms several loops, passing alternately over four rollers or rollers with fixed axes 6, 7, 8 and 9, and three rollers or rollers 10, 11 and 12 whose axes are mounted on an arm 13 pivotable about a fixed axis 14.
  • the bou They are more or less large depending on the position occupied by the arm 13, a position which depends on the tension exerted by the aluminum film and on the diameter of the coil mounted on the reel.
  • a tension spring 15 At one end of the arm 14 is fixed the end of a tension spring 15, which tends to tilt the arm 14 in the direction of the arrow 16 around its pivot axis 14.
  • the packaging material passes over a roller 17 mounted on a support 18 pivotable about a fixed axis 19.
  • This support is integral with a rod 20 which can be translated between two extreme positions, under the action of 'an electromagnet 21.
  • the roller 17 In its position shown in solid lines, the roller 17 is set back, while in its position 17' illustrated in broken lines, it is in front and rests on a roller 22 ' fixed axis. After the roller 17, the packaging material passes over a last roller 23 which causes it to change direction, before being finally pinched between two continuous or intermittent drive rollers 24 and 25 and passing in front of a cutting device 26 shown schematically. A non-return device 27 is mounted above the strip of packaging material, upstream of the roller 17.
  • the device of fig. 1 actually consists of a second set of elements similar to those which have just been described.
  • This assembly comprises, as previously, a reel 31, the spindle 32 of which supports a reel of unopened packaging material 33.
  • the spindle of the reel is driven by a drive motor 34 identical to the motor 4.
  • the packaging material in the form of a very thin aluminum film 35, is unwound by making a certain number of loops obtained by virtue of the fact that it passes alternately over the rollers of fixed axes 36 , 37, 38 and 39 and on the rollers 40, 41 and 42, the axes of which are mounted on an arm 43 pivoting around a fixed axis 44 biased, on the one hand by a spring 45 in the direction of the arrow 46 , and secondly by the traction exerted on the film 35 when it is engaged between the drive rollers 24 and 25.
  • a non-return device 47 is mounted above the film, located in this case upstream of roller 22.
  • the two assemblies described above also include a first incremental pulse generator 48, the reference disc 49 of which is driven in synchronism with the drive rollers 24 and 25, a second. incremental pulse generator 50, whose reference disc 51 is driven in synchronism with spindle 2 of the reel 1 by the drive motor 4 and a third incremental pulse generator 52, whose reference disc 53 is driven by the motor 34, in synchronism with the spindle 32 of the reel 31.
  • the arm 13 carries an arcuate segment 54 comprising a succession of coding areas, intended to identify the position of said arm by means of a detector55.
  • This arc segment carries for example three superimposed lines of black or white areas. Each line has, in the example shown, six ranges. A total of eighteen ranges are shown, which correspond to six three-bit codes. In fact, the part of the segment which does not have a range also corresponds to a three-bit code (three black areas) and the area fictitiously extending the segment beyond the coding ranges also corresponds to an eighth three-bit code ( three white areas).
  • the distribution of the tracks and their number can be arbitrary depending on the information that one wishes to encode and decode.
  • the arm 43 carries an arcuate segment 56 identical to the segment 54 and intended to allow the location in position of said arm 43 by means of a detector 57.
  • Two switches 58 and 59 arranged so as to be engaged or triggered according to the position of the arms 13 and 43 respectively, control the start or stop of the drive motors 4 and 34.
  • the packaging material supply device is supplied by the reel 1 partially opened.
  • the spindle 2 is driven by the drive motor 4 by means, for example, of a toothed belt.
  • the packaging material is driven towards the cutting device 26 by the two drive routers 24 and 25.
  • the packaging material is pulled by the drive rollers, the reel unwinding. only due to the pull on the strip of packaging material. This principle cannot be used with an aluminum film 9 to 10 ⁇ thick, the traction which it would be necessary to exert on said material to unwind the reel being greater than its mechanical strength.
  • the tensile force exerted by the drive rollers exerts a tension on the packaging material, which tends to pivot the arm 13 in the opposite direction to the arrow 16, an action which is counteracted by the traction of the spring 15.
  • the drive motor 102 of the spindle of the wire feeder 101 rotates at a speed which is controlled by a control signal called the setpoint proportional to the frequency of the pulses generated by the pulse generator 103.
  • the frequency of the speed setpoint is modified during operation of the device according to the code read by the detector 104 on the arcuate segment carrying the coding ranges 105.
  • a position of the swinging arm 106 corresponds to a given diameter of the reel of packaging material currently in use on which is mounted the arcuate segment carrying the coding pads 105. This position is generally not rigid, but oscillates between two coding pads. As the diameter of the coil decreases from its maximum diameter to its minimum diameter, the swingarm moves clockwise.
  • the frequency of the speed setpoint F e determined by the pulse generator 103 is introduced into a multiplier 107 which multiplies this frequency by a coefficient K which is a digital factor depending on the code detected by the detector 104.
  • the output signal F ee known as the modified speed reference frequency from the multiplier 107, is transmitted to a frequency-voltage converter 108 which transmits a voltage U ee , called the modified speed reference voltage, to a comparator 109.
  • This comparator also receives a voltage U M called the measured speed voltage, transmitted by a frequency-voltage converter 110, the input signal of which is a measured frequency signal F m supplied by a digital tacho dynamo 111, rotating in synchronism with the drive motor 102.
  • the comparator supplies an output signal to a regulator at four dials 112 which then regulates the speed of the drive motor 102 via a conventional closed loop adjustment circuit.
  • the end of the strip 35 of the reel 33 was brought manually onto the roll 22 and provided, on its upper surface, with a double-sided adhesive strip, so that the support of the roll 17 on the roller 22 generates a bonding of the terminal end of the reel 3, on the beginning of the strip of the reel 33.
  • the start of the signal actuating the electromagnet 21 also generates the switching cycle of the motor 4 on the motor 34 and of all the satellite elements of the reel 1 on the satellite elements of the reel 31.
  • the motor 34 is stopped.
  • the arm 43 moves counterclockwise and actuates the safety switch 59.
  • This switch starts the motor 34, the arm 43 adopting an equilibrium position as a function of the momentary diameter of the coil 33.
  • a detector 61 provides an end-of-band signal which acts in particular on the electromagnet 21, to bond the end of the strip 35 to a new strip 5, which has meanwhile been placed on the reel 1.
  • the present invention makes it possible to supply continuously, precisely and efficiently, a packaging machine with very thin packaging material. Thanks to the electronic end of strip detector and the electromechanical control of the gluing of one end of the strip at the beginning of the next strip, it is possible to obtain, at each change of reel, a section of packaging material in duplicate thickness, of constant length, this length being as small as possible.
