Definitions

  • This invention relates to a device for unwinding and rewinding reels of labels or other self-adhesive documents in the form of continuous modules which are mounted on a siliconized support, said device being adapted for use along with overprinting machines of electronic type.
  • the invention is concerned with the separation of the label from its support or backing during the rewinding process.
  • the overprinting machines for self-adhesive labels or the like at present commercially available are basically in the following overprint types.
  • All of these embodiments provide the displacement or shifting of the label or the like when overprint is being carried out, or at the immediately preceding moment, but in any case by a spacing equal to an entire label at a time, by using an A.C. or D.C. motor.
  • This motor moves the paper only once by a full pitch (a pitch includes a label and the inter space between two successive labels) using this space as a reference. This is because the force required for separating the label or the like from its support or backing can be effected only by a motor developing a certain torque.
  • a text conposition requires some time which does not allow the use of this type of machines for limited series of labels.
  • the use of these printing machines becomes particularly difficult when producing labels, in which the variability of the text to be written and the number of variables is such that the amount of identical labels is so small to require the use of writing units of the type used on priners for processors, thus excluding preformed planar matrices or cylindrical matrices with composition of metal or synthetic letters.
  • the use of these printing machines should also be avoided when the paper transport cannot be carried out by the punched side bands as in the printers.
  • Jhe above mentioned objects have been accomplished by carrying out the paper transport by means of an electronically controlled step-motor, while a friction rewinding means provides the required torque for carrying out the separation of a label or the like from its support or backing.
  • the device carrying out the above described conditions is particularly a device comprising a set of rollers supporting and guiding the band of overprintable material to the writing station and beyond to rewinding, and a step-motor for the band transport, which provides for carrying the band along through a drawing roller in the intervals between the writing of a line and the next line, effecting electronically controlled and preset intermittent angular rotations, a friction rewinding means being provided.
  • said friction rewinding means is driven through a clutch by said step-motor.
  • a second embodiment contemplates that the rewinding means is provided by a continuously rotating motor, which preferably trasmits a high constant torque through a clutch.
  • the paper transport is obtained by means of a constant high torque as defined by the clutch calibration; this torque is substracted by (band stop) or added with (band movement) the torque developed by the step-motor.
  • the adjustable orientation for at least one roller or for the whole writing plane is provided.
  • the friction rewinding means is of high adherence or knurled, and particularly the label band is caused to slide with the labels facing the outer surface of the roller forming the friction rewinding means.
  • An improvement to the invention is obtained by carrying out the several kinematic movements of the rollers by means of toothed pulleys and belts, whereby the mutual angular position is assured.
  • Another improvement to the invention is obtained by providing that the angular rotation by each pitch of the step-motor will cause the advancement of the reel by a full writing height, or preferably- by a full fraction of the minimum writing height provided.
  • Figs. 1 and 2 Some unrestrictive embodiments of the device according to the invention have been outlined in Figs. 1 and 2, showing perspective views of two embodiments according to the present invention.
  • an unwinding roller 1 an idle roller 2 acting as a damper for the pulls due to each single forward movement of the step-motor, the writing plane 3, that is the plane on which the needle writing head (not shown for the sake of sinplicity) will write, the drawing roller 4 coated with a knurling 4b providing a high adherence, the counter-drawing roller 5 also knurled, the rewinding roller 6, the step-motor 7, the drawing belt 8 for the latter, the drawing clutch 9 which can be adjusted by a spring, the reel 10 of labels to be overprinted, the recovery reel 11, and the photocell 12 for signalling the label end.
  • roller 4 is provided with a coating 4a having a high adherence, for example rubber.
  • the D.C. rewinding motor has been denoted, at l4 the plane on which the brush 15 bears and improves the adherence of the label band on roller 4, 16 counter-rollers, 17 the clutch adjusting knob, and 18 the cam for the angular adjustment of the writing plane.
  • the sliding direction for the band to be overprinted is shown by the arrows.
  • the writing unit has not been shown in the drawing as it comprises a conventional needle head and a conventional inked ribbon, both of the type used on the printers of microprocessors.
  • the electronics governing the control of the motor and photocell has also not been shown in the drawing.
  • the two figures of the drawing show two versions of the same device. They basically differ as in Fig. 1 (the most elementary version) there is only one motor 7, while in Fig. 2 the rewinding motor is also shown.
  • the movement of the label band occurs when the torque of the rewinding motor 13 adds to the moving torque of the step-motor 7.
  • Stop occurs when the stop torque of the step-motor 7 is subtracted from the torque of the rewinding motor 13.
  • the torque of the rewinding motor 13 is defined by the calibration of clutch 9 and remains constant for a given calibration of the clutch.
  • the print end for each label is sensed by the photocell 12 which could be replaced by a switch (not shown) sensing the change in thickness of the band (only support or support plus label).
