Definitions

  • This invention relates to apparatus for printing and decorating metal and similar substantially stiff material in continuous strip form, and refers more particularly to means for so controlling the rotation of the impression roller or rollers in such apparatus that the successive impressions made thereby are all located at regularly spaced intervals along the length of the strip.
  • a major problem is synchronizing the rotation of the impression roller, carrying the image to be reproduced, with the lengthwise motion of the strip, so that the successive impressions made by the impression roller are at uniformly spaced predetermined intervals along the strip.
  • register is usually employed in the graphic arts to denote the correct relationship to one another of two or more successively made impression that occupy a single imprint area on a web or sheet being imprinted, it will be seen that the term is applicable also, at least in an analogous sense, to designate the correct relationship to one another of two or more impressions occupying diiferent but adjacent imprint areas along the length or across the width of a strip or web, and the term register is sometimes used herein in that sense. More specifically, the present invention is concerned with the problem of obtaining register (in the specialized meaning thereof) lengthwise along a strip .or web.
  • the strip is trained partway around a backup roller which also serves as a monitor roller.
  • the backup and impression rollers are driven by separate hydraulic motors to which pressure fluid is supplied from a constant pressure variable-volume main pump.
  • the torque thus applied to the rollers is of a constant value such as to rotate them at circumferential speeds that correspond to the nominal local linear speed of the strip at the printing station; but for a number of reasons,'discussed at length in the Kinzelman patent, the actual local linear speed of the strip can and does frequently vary from its nominal speed.
  • the backup roller derives energy from the moving strip, through its frictional contact therewith, and applies such energy to the impression roller to modify its speed.
  • the hydraulic motor by which the backup roller is driven is connected in the hydraulic circuit in series between the main pump and the drive motor for the impression roller, and it acts as an auxiliary pump which modifies the output of the main pump to vary the speed of the impression roller drive motor in correspondence with variations in strip speed.
  • the long term register control comprises a socalled walking wheel, which is driven by the impression roller drive motor to rotate at exactly the circumferential speed of the impression roller and which rotates in engagement with the strip at a monitoring station adjacent to the impression roller.
  • the walking wheel is mounted on a lengthwise flexible shaft, and hence when the linear speed of the strip portion engaged therewith varies from the circumferential speed of the walking wheel, the latter moves lengthwise along the strip, in one direction or the other, at a rate dependent upon the discrepancy between the speeds of the strip and the impression roller.
  • an output is produced which varies with the movement of the Walking wheel lengthwise of the strip and this output is used to vary the displacement of the hydraulic motor which drives the impression roller, to bring the circumferential speed of the impression roller back into synchronism with the speed of the strip.
  • the long term register system is incapable of following rapid changes in strip speed; and since rapid strip speed changes are also likely to produce slippage of the strip over the backup roll, the apparatus of the Kinzelman patent affords no dependable means for correcting for errors due to such rapid local accelerations and decelerations of the strip.
  • Kinzelman apparatus is speed responsive, rather than being responsive to discrepancies between the actual angular position of the impression roller at any instant and its desired angular position at that instant, its desired angular position being that which it should have if the impression that it is making is to be in register with all other impressions lengthwise along the strip.
  • the series of impressions that follows the long impression may be in register with its trailing edge, and with one another, but they will not necessarily be in register with the impressions of the first series.
  • the long term register control may bring impressions of the second series back into register with those of the first series, but only after a substantial number of impressions of the second series has been made.
  • the delay in resuming such register will of course be dependent upon the amount of damping incorporated in the long term register system.
  • Another object of this invention is to provide apparatus for register control which achieves the above stated objectives and which allows the strip to follow a straight path through the printing station, if desired, or, if preferred, enables it to be curved partway around the backup roller so as to undergo a change of direction at the printing station, and which, moreover, can be employed with both offset and direct impression printing apparatus.
  • Still another object of this invention is to provide register control apparatus of the character described having a monitor roller carried by a rigid but freely rotatable shaft and which is rotatably driven by the strip and in turn drives a position responsive electrical instrumentality that presents a light load to the strip through the monitor roller so that the rotational position of the monitor roller is at all times accurately related to the length of the strip that has been fed past it.
  • register control apparatus of the character described which comprises a monitor roller, mounted at a monitoring station adjacent to the impression roller and engaged with the strip to be rotated thereby, for producing an output that is a function of the length of the strip fed past the monitoring station, and feedback means directly connected with the impression roller, to be accurately responsive to its angular position, whereby a second output is produced that is balanced against, or compared with, the output produced by the monitor roller to thus yield a control output which is applied to the regulation of the instantaneous angular position of the impression roller, and wherein the magnitude of the control output is always proportional to the amount of discrepancy in the angular position of the impression roller, so that the system is stable and self-damping.
  • a further specific object of this invention is to provide control apparatus of the character described which comprises comparatively simple and dependable apparatus, much of which is readily available as standard equipment.
  • FIG. 1 illustrates one complete example of the physical embodiment of the invention constructed according to the best mode so far devised for the practical application of the principles thereof, and in which the single FIGURE is a more or less diagrammatic side perspective view of printing apparatus embodying the principles of this invention.
  • the numeral 5 designates generally a strip of metal or similar stiff material having very substantial length and which is to be imprinted or decorated by means of the apparatus of. this invention, designated generally by 6.
  • the strip follows a defined path that carries it from a source, such as a supply reel 7, successively through hold back rolls 8, a printing station 9, and pull through rolls 10, and finally to a rewind stand 11 at which the strip is wound into a compact coil.
  • a source such as a supply reel 7, successively through hold back rolls 8, a printing station 9, and pull through rolls 10, and finally to a rewind stand 11 at which the strip is wound into a compact coil.
  • a coating or lacquering station an oven through which the-strip passes after it leaves the printing station, and a cooler through which it passes after leaving the oven. Only those stations are herein illustrated which are directly related to the imprinting of impressions that are in lengthwise register with one another along the length of the strip.
  • the strip is drawn through the machine by the pull through rolls 10, which are drivingly connected, through transmission means 12, with an electric motor '13 or other drive means.
  • the pull through rolls tend to move the strip lengthwise at a substantially uniform speed, but for a. number of reasons, explained at length in the aforesaid Kinzelman patent, the local linear speed of the strip at any given station in the machine, and notably at the printing station 9 with which this invention is primarily concerned, may fluctuate moreor less substantially above and below the nominal driving speed of the pull through rolls.
  • the hold back rolls 3 are'provided with suitable rotation inhibiting means (not shown) by which they are caused to resist forward movement of the strip, without, however, actually preventing its advance through the machine.
  • the rewind reel 11 is suitably driven in a manner well known to those skilled in the art so as to wind the strip material into a coil at the same rate that it emerges from the machine.
  • the strip passes through one or more printing couples (two printing couples being shown in the present case), each comprising an impression roller 16 and a backup roller 17. It is not material to the present invention whether the strip follows a perfectly straight path through the printing station or is partially wrapped around each backup roller or otherwise made to undergo one or more changes of direction in the course of its progress through the printing couples, In
  • the printing couples are shown as being arranged to define a horizontal path along which the strip moves in a straight line through the printing station.
  • the impression roller 16 of each printing couple can comprise, as shown, a blanket or transfer roller cooperable with a. plate roller 18, as in offset printing, or it could be a roller of the direct impression type.
  • Each of the backup rollers 17 is an idler that rotates in consequence of its circumferential engagement with the strip.
  • rollers herein mentioned are supported on suitable frame means (not shown) for rotation on axes which are fixed along the path of strip travel and which extend parallel to one another and transversely to the length of the strip.
  • Each of the impression rollers is driven by a synchronous electric motor 20 or other constant speed prime mover, through variable speed transmission means 22, so that the impression rollers rotate entirely independently of their engagement with the strip.
  • the variable speed transmission means for each impression roller is constantly adjustable to maintain the angular position of the impression roller at all times in exactly a predetermined relationship to the length of the strip that has moved past the impression roller, so that each successive impression will occupy a predetermined space along the length of the strip such as to be in lengthwise register with all of the impressions previously made by the impression roller.
  • the ratio between the rate of angular displacement of the impression roller and the linear speed of the strip is such that the circumferential speed of the impression roller is maintained exactly equal to the local linear speed of the strip, but in some special circumstances the impression roller circumferential speed might be maintained at some other predetermined ratio to strip speed, and even in that case the selected ratio can be exactly and constantly maintained by the method and apparatus of this invention, despite fluctuations in local strip speed.
  • the variable speed transmission means 22 for each printing couple comprises a pair of transmissions 23 and 48 connected in series.
  • the transmission 23, which is manually controllable, is connected directly to the drive motor 29 and provides for relatively coarse adjustment over a wide range of speeds, to enable the circumferential speed of the impression roller to be brought into approximate equality with linear strip speed, so that the corrections which must be made by the automatic control apparatus will not exceed its operating range.
  • the other transmission 43 is adjusted by means of the control apparatus and is interposed between the manually controlled transmission 23 and the impression roller.
  • the automatically controlled transmission 48 provides for a substantially narrower range of speed variations to enable the control apparatus to effect very fine adjustments of impression roller speed.
  • control apparatus for each impression roller comprises a monitor roller 24 which is mounted at a location adjacent to the printing couple or couples to have its periphery engaged with the strip for rotation thereby, a self synchronous alternator (sometimes re ferred to as a synchro control transformer, or simply a synchro) 25 which is driven by the monitor roller, a self synchronous alternator (sometimes re ferred to as a synchro control transformer, or simply a synchro) 25 which is driven by the monitor roller, a self synchronous alternator (sometimes re ferred to as a synchro control transformer, or simply a synchro) 25 which is driven by the monitor roller, a self synchronous alternator (sometimes re ferred to as a synchro control transformer, or simply a synchro) 25 which is driven by the monitor roller, a self synchronous alternator (sometimes re ferred to as a synchro control transformer, or simply a synchro) 25 which is driven by the monitor roller, a self synchronous alternator (sometimes re ferred to as
  • second synchro 26 which is drivingly connected with the impression roller, an amplifier 27 having output terminals 29 and input terminals 28 into which the output of the synchros is fed, and a two-phase servo motor 30 connected with the output terminals of the amplifier and which effects regulation of the automatically controlled variable speed transmission 48.
  • the monitor roller 24 rotates on a fixed axis and comprises a wheel having a resilient tire 31 that peripherally engages the strip at a point just ahead of where it enters the printing couples.
  • the monitor roller is mounted as close as possible to the printing couples to insure that the local linear speed of the strip at the monitoring station is always exactly equal to the local linear speed of that portion of the strip which is engaged by the impression rollers, or, in other words, to insure that the length of strip fed past the monitor roller station always bears an exact relationship to the length that has passed each impression roller.
  • the angular position of the monitor roller is always exactly a predetermined function of the length of strip that has passed in engagement with each impression roller.
  • the diameter of the monitor roller be identical to that of the impression rollers, so that the rate of angular displacement of the monitor roller will be the same as that of the impression rollers when the latter are in step with the strip.
  • the circumference of the monitor roller will differ from that of the impression roller by such an amount as to give said rollers equal rates of angular displacement when the impression rollers are in step with the strip. Since there must always be a predetermined ratio between the diameters of the monitor and impression rollers, the monitor roller should be detachably secured on its shaft 32 to facilitate setting up the press for different jobs.
  • the two synchros should have identical characteristics, and the shafts 32 and 33 which connect them with the respective rollers by which they are driven should be rigid and free from whip and backlash.
  • the shaft 32 for the monitor roller should be supported with particular attention to minimizing rotational friction, so that the monitor roller and its associated synchro present the least possible load to the strip.
  • the synchros offer only very light loads to the rollers by which they are driven, and this is particularly important in the case of the monitor roller driven synchro 25 because it assures against slippage between the monitor roller and the strip.
  • the rotor terminals R1 and R2 of one synchro (in this case the synchro 25 which is driven by the monitor roller) are connected with a source of reference AG. by means of conductors 36 and 37.
  • the corresponding stator terminals S1, S2 and S3 of the two synchros are connected with one another by means of conductors 38, 39 and 40, so that the alternating currents induced in the stator of synchro 25 will have exact counterparts in the stator of synchro 26.
  • the currents in the stator of synchro 26 constitute the output of the synchro 25, since their characteristics at any instant depend upon the angular position at which the rotor of synchro 25 is disposed at that instant by the monitor roller.
  • synchro 26 produces a feedback as well as an output, since the voltage appearing at its terminals R1 and R2 differs in phase from the reference A.C. only when, and to the extent that, the rotor of synchro 26 is disposed at a diiferent angle than the rotor of synchro 25, and this regardless of the absolute speeds of the rotors of the two synchros.
  • the AC. appearing across the terminals R1 and R2 of synchro 26 must, in effect, be compared with the reference A.C., and this is done by connecting the output terminals 29 of the amplifier, by means of conductors 44, with the terminals 45 of one phase winding of the two-phase servo motor 30, while the reference A.C. source is connected, by means of conductors 46, with the terminals47' of the other phase winding of the servo motor.
  • phase relationship between the two alternating currents applied to the servo motor will be a function of the angular relationship of the rotors of the two synchros, or, in other words, of the relationship between the length of strip that has passed the monitor roller, and the position of rotation of the impression roller.
  • the magnitude of any phase difference between said A.C.s will be proportional to the amount of the angular difference between the monitor and impression rollers, and the phase polarity of the error signal will depend upon whether the impression roller is angularly in advance of or behind the monitor roller.
  • the servo motor will exert no torque when the error signal is zero, because the in-phase A.C.s applied to its respective phase windings will balance or offset one another.
  • the amplifier output being out of phase with the reference A.C., will cause the servo to rotate in the direction to effect an adjustment of the variable speed transmission means by which the speed of the impression roller is increased or decreased to bring it back into angular correspondence with the monitor roller. Since the rate of rotation of the servo motor is proportional to the magnitude of the difference in synchro rotor angles, the servo motor tends to be self damping, and the system therefore has no tendency to hunt.
  • the manually adjustable variable speed transmission 23 is adapted to be used, in conjunction with a null meter 50, to bring the monitor and impression rollers into approximate, synchronization before the automatic control is placed in operation.
  • the null meter is a D.C. voltmeter of conventional type, so calibrated, however, that its needle is on a zero marker at the center of its scale when a D.C. of one polarity and an arbitrarily selected value is applied to it.
  • the reference A.C. source is connected to one of the primary windings 52 of a three winding transformer 53 -by means of conductors 54, while the other primary 55 of the transformer is connected with the terminals R1 and R2 of synchro 26 by means of conductors 56 which are in parallel-with the amplifier input leads 42 and 43.
  • the transformer in effect adds the two A.C. voltages algebraically and produces an output in its secondary 57 which is proportional to the difference in their phase.
  • phase shift control 58 connected with the terminals of one primary (in this case the primary 55) provides for maintenance of the proper phase relationship between the transformer primary inputs so that when the output of synchro 26 is in phase with the reference A.C. voltage across the transformer secondary will be zero, while if the primary inputs are out of phase the secondary output will be an AC. voltage of a value determined by the transformer ratio.
  • the A.C.. output of the transformer secondary is rectified and filtered by means of a half-wave rectifier 59 connected in series with the secondary and the meter and a condenser 60 connected across the secondary terminals.
  • the transformer output is thus applied to the meter as a direct current.
  • a potentiometer 62 in series with the meter and transformer secondary provides for adjustment of the maximum voltage that can be applied to the meter, to maintain the voltage within the scale of he meter while permitting the meter to swing to its maximum reading when the voltages across the two transformer primaries are out of phase.
  • a source 63 of D.C. bias in parallel with a zeroing potentiometer 64, is also connected in the meter circuit to bring the meter needle to its center position when the voltages across the transformer primaries are in phase. This is necessary because the meter is a. conventional D.C. voltmeter, and its needle would otherwise swing to one end of the scale (its normal zero position) under these circumstances.
  • the two synchro rotors When, under these conditions, the meter needle swings, to its zero point from one side thereof, the two synchro rotors will have corresponding angles just as it reaches the zero point, and the amplifier can be switchedon at that instant to enable the automatic control system to take over the regulation of the impression roller.
  • the two synchro rotors When the meter needle swings to its zero point from the other side thereof, the two synchro rotors will be in angular positions that are 180 apart asthe meter needle crosses the zero mark, and if the amplifier were switched on at that time, the system would not have stable operation.
  • the manually controllable variable speed transmission 23 enables the circumferential speed of the impression roller to be brought so nearly into synchronism with strip speed that the movement of the meter needle takes place at a very slow rate, and hence it is an easy matter for the operator to turn on the amplifier just as the needle reaches its stable condition null.
  • the amplifier is either transistorized or, if it has vacuum tubes, the filaments are energized during the preliminary manual adjustment of the apparatus, so that the amplifier goes into operation the moment it is turned on, without an intervening warm-up period.
  • impression rollers are used, they .can be geared together and driven by a single motor and variable speed transmission means, or they can be separately driven, as shown, each by its own motor and varia ble speed transmission means.
  • each impression roller is drivingly connected with a synchro 26 that has its stator terminals S1, S2 and S3 connected with the corresponding terminals of the synchro 25 driven by the single monitor roller.
  • Each of the impression roller driven synchros 26 has its rotor terminals R1 and R2 connected to the input terminals of a separate amplifier, which in turn has its output terminals connected to a servo motor 30 for the variable speed transmission means associated with that impression roller.
  • this invention provides means for so controlling the rotational speed of an impression roller, in apparatus for imprinting metal and other substantially stiff material in continuous strip form, as to at all times maintain its angular position in a predetermined relationship to the length of strip that has passed it, so that all of the successive impressions made by the impression roller are in accurate register with one another along the length of the strip.
  • the control apparatus of this invention is simple, dependable and inexpensive, and is capable of keeping the impression roller in step with the strip despite rapid changes in strip speed and without hunting or requiring damping that would slow the responses of the system.
