Definitions

  • the present invention relates to a method for treating defective labels, in particular RFI D labels, in a label printer according to the preamble of claim 1 and a label printer for printing labels, in particular for carrying out a method for treating defective labels, preferably RFID labels, according to the preamble of claim 20.
  • labels can be used for a wide variety of purposes.
  • labels are arranged on products as goods information carriers for end consumers, but can also be attached to goods or goods containers to be sent or delivered as transport information and / or inventory information carriers.
  • labels are known for this purpose, which can be printed with the desired information by means of a label printer.
  • the information can be printed on the label both in plain text, ie in a form that can also be read directly by a customer, recipient, etc., and in the form of barcodes, etc., in accordance with a corresponding requirement.
  • labels have become known in practice which are provided with electronic storage means into which the respective information can be temporarily or continuously written and / or read out by means of radio waves.
  • Such labels are usually referred to as RFID labels.
  • a label carrier such as a conventional paper label
  • radio signals which are incorporated in a label carrier, such as a conventional paper label, and which can be written on and / or read out by means of radio signals.
  • Different frequency bands are used, such as the HF band (6 MHz to 30 MHz), the UHF band (30 MHz to 300 MHz) or the UHF band (300 MHz to 3,000 MHz).
  • these previously known labels were printed or written on and / or read out in any case and then from the printing or writing and / or Output reader unit to be applied to the respective object to be marked. If the label was already damaged at the time of printing or writing and / or reading, the label was marked as such, e.g. B. by printing a black bar. An operator then manually removed the label from the label carrier web. In the latter case, a damaged label meant that the information on it or in it could not be read correctly when the item marked in this way was further handled, and thus there was also a faulty control or incorrect inventory or a non-purchase of the item marked in this way ,
  • the above object is achieved by the features of claim 1.
  • a defective label is recognized and this prevents the defective label from being dispensed to the object to be labeled or applied there.
  • the dispensing process of such a label on the object is suppressed and, as will be explained in more detail below, the defective label is otherwise disposed of.
  • the label can be a printable label, a pure RFID label or a label that represents a combination of a printable label and an RFID label. If the label is an RFID label, then all frequency bands used for RFID labels can be used.
  • the frequencies or frequency ranges of the HF, VHF or UHF range are preferred, preferably 6 MHz to 30 MHz, in particular 13.56 MHz, 30 MHz to 300 MHz, 300 MHz to 3,000 MHz, but also 125 kHz up to 135 KHz and 3 GHz to 30 GHz, in particular 2.45 GHz.
  • the first writing unit is a writing printing unit, for example in the form of a thermal transfer printing unit, in the case of a pure RFID label an RFID writing and / or reading unit and in the case of a combined label, ie of a printable label with an RFID section, which can be a writing printing unit or an RFID writing and / or reading unit.
  • a writing printing unit for example in the form of a thermal transfer printing unit
  • an RFID writing and / or reading unit in the case of a combined label with an RFID section
  • a combined label ie of a printable label with an RFID section
  • several writing units or a combination of writing and Reading units may be provided, these units being optional the units mentioned above.
  • the labels can be arranged on the label carrier web while maintaining the same or unequal spacing or immediately after one another.
  • the labels can have a width, i.e. have an extension transverse to the conveying direction of the label carrier web, which is smaller than the width of the label carrier web.
  • the labels can also have the same width as the label carrier web.
  • the labels can be held on the label carrier web by means of an adhesive layer applied at least partially on their side facing the label carrier web, the label carrier web being provided on its side facing the label with a coating which adheres the label with its adhesive layer to the label carrier web allowed, but also allows the label to be detached from the label carrier web without destroying the adhesive layer.
  • the label carrier web and the label thereon can also be completely or partially covered by a cover layer, which in the case of printable labels after the printing process on the combination of label carrier web and label, in the case of pure RFID labels before or after the reading and / or writing process and, in the case of a combination of RFID label and printable label, can be applied to the label after the printing process.
  • This cover layer primarily serves to protect the label on the object provided with the label, in particular against unauthorized detachment of the label from the object and / or penetrating moisture.
  • the label has at least one printable section or an imprint carrier section and an RFID section, the test unit checking at least the RFID section for defects.
  • the RFID section and the printable section of the label can be arranged one behind the other in the conveying direction of the label carrier web as well as coincident with one another.
  • the test unit can also check the printable section for defects, for example Check cracks, color defects, etc. It is preferred for the RFID section that it operates in a frequency range from 300 MHz to 3,000 MHz.
  • the testing unit is or is arranged in the conveying direction of the label carrier web in front of the first writing unit.
  • a particularly space-saving solution is achieved in that the test unit is formed by the RFID reading and / or writing unit used for the reading and / or writing process on the RFID section of the label.
  • the test unit is the RFID reading and / or writing unit, so that a label printer designed in this way according to the invention has two writing units, the first writing unit for applying an imprint on the printable section of the label and an RFID reading as the second writing unit - And / or writing unit for reading and / or writing on the RFID section of the label.
  • both a test unit in the form of an RFID reading unit and an RFID can -Reading and / or writing unit are used.
  • a thermal transfer printing unit for example, can then be provided in the writing unit for a label that can only be printed or the printable section of an RFID label with a printable section. If the label is only a label to be printed, the test unit can be formed by a scanner, a CCD camera, etc.
  • an essential aspect of the invention is that the label, which the test unit judges to be defective, is not carried out or dispensed on the object to be labeled with the label, but is otherwise disposed of.
  • the label recognized by the test unit as defective remains on the label carrier web and is taken up together with the label carrier web in the empties store.
  • the label can be detached from the label carrier web in very different ways. One possibility is to manually detach the respective label from the label carrier web.
  • a dispensing unit can be provided at the exit opening of the label printer which has a dispensing edge on which the label carrier web is deflected over a small, preferably very small radius, the label being deflected detaches from the label carrier web.
  • a dispensing unit in order to convey a defective label together with the label carrier web into the empties storage unit, provision can be made that the tensile stress of the label carrier web is reduced in such a way that the deflection radius of the label carrier web at the dispensing edge increases to such an extent that the label is not detached from the label carrier web.
  • the deflection radius can also be increased while at least approximately maintaining the tension, in such a way that the label carrier web assumes a larger deflection radius in the region of the dispensing edge. It is therefore advantageous if, in the case of a defective label, the tensile stress of the label carrier web is reduced so that the deflection radius of the label carrier web at the dispensing edge is greater than the radius of the dispensing edge, so that the label is detached from the label carrier web at the dispensing unit or Dispensing edge is omitted.
  • the dispensing edge can have both a curved surface, even if it has only a very small radius, and a design that only shows a line contact with the label carrier web.
  • Known label printing devices or label printers have a conveyor unit which has at least a first drive unit arranged upstream of the dispensing unit in the conveying direction of the label carrier web and at least a second drive unit which are both downstream and apply tensile stress to the label carrier web.
  • the drive device of the first and the second drive unit can be selected differently.
  • the difference in the drive power can be brought about by different rotational speeds for the first and the second drive unit, in particular the speed of the second drive roller can be chosen to be less than the speed of the first drive roller so that the first drive roller advances the label carrier web faster than the second drive roller which then exerts a braking effect on the label carrier web, as a result of which a loop is formed at the dispensing edge in the label carrier web, the radius of which is greater than the radius of the dispensing edge of the dispensing unit.
  • the second drive roller is stopped, whereas the first drive roller continues to be operated.
  • the first drive roller then pushes the label carrier web further, whereas the second drive roller holds the label carrier web so that a loop is formed in the area of the dispensing unit or the dispensing edge in the label carrier web, the radius of which is greater than the radius of the dispensing edge.
  • a further possibility for forming the enlarged radius in the label carrier web at the dispensing edge or the dispensing unit by reducing the tensile stress of the label carrier web is that the first drive roller is stopped and the second drive roller is operated against the normal direction of conveying rotation. In other words, the second drive roller is operated in reverse, so that the label carrier material that has already passed the dispensing edge in the conveying direction is conveyed back in the direction of the dispensing unit or dispensing edge, which likewise forms a loop in the label carrier web, the radius of which is greater than the radius the donation edge.
  • the next label, which is defective can then be guided past the dispensing edge along the larger deflection radius without this label detaching from the label carrier web and being dispensed.
  • a further possibility for preventing the defective label from being dispensed or applied to the object to be identified is that the deflection radius of the label carrier web at the dispensing edge is increased compared to the radius of the dispensing edge.
  • this increase in the deflection radius can be brought about by reducing the tensile stress of the label carrier web.
  • Another possibility is to achieve this increase in the deflection radius by means of an actuator.
  • This can be, for example, a deflection roller with a large radius that is introduced into the conveying path of the label carrier web.
  • This deflection roller is first introduced into the conveyor path of the label carrier web in such a way that its outer circumferential side lies tangentially on the label carrier web. It can then be moved continuously in a direction transverse to the broad direction of the label carrier web, while maintaining the tensile stress, whereby it moves continuously or step by step. the deflection radius at the dispensing edge is increased.
  • An alternative embodiment for the actuator can be done in that the dispensing unit in at least one. first working position in which the dispensing process takes place and can be moved into at least one second working position in which the dispensing process does not take place.
  • the dispensing unit forms a switch, by means of which it is possible to dispense an intact label and to convey a defective label together with the label carrier web into the empties storage unit.
  • the donation unit can be moved into the first or second working position depending on the test result of the test unit.
  • the dispensing edge of the dispensing unit is or is provided with at least one first curved functional surface, which serves as the dispensing edge, and at least one second curved functional surface ., wherein the radius of curvature of the first functional surface is selected to be smaller than the radius of curvature of the second functional surface.
  • the first curved functional surface can have a radius of curvature greater than zero or a radius of curvature equal to zero, in the latter case the curved functional surface being designed as a dispensing edge in the narrower sense, which only has a line contact with the label carrier web.
  • Another possibility of preventing the delivery of a defective label to an object to be identified is to dispense the defective label to a collecting unit for defective labels.
  • the defective label is donated, but not to the object to be marked with it, but to a collection unit specially provided for this purpose.
  • the collection unit can be designed differently.
  • the collecting unit can be a plate running parallel to the direction of movement of the dispensed label or a plate-shaped element on which the defective label is dispensed.
  • the collecting unit can be moved, in particular pivoted, into the dispensing path of a label to be dispensed.
  • the plate-shaped element of the collecting unit is also aligned horizontally. In this case it is advantageous if the collecting unit can be moved vertically.
  • a further possibility of the collecting unit consists in a roller, which is located in the conveying direction of the label carrier web upstream of the dispensing unit outside or possibly also inside the printer housing and for receiving several defective labels continuously or discontinuously is drivable.
  • the roller can be provided with an adhesive coating once or several times in succession. The latter can be done, for example, by the roller running past a unit applying an adhesive layer, which also applies the adhesive to labels already on the roller.
  • an electronic control unit which optionally has a CPU which is freely programmable.
  • the test unit or the RFID reading and / or writing unit and / or the writing printing unit and / or the dispensing unit and / or the conveying unit can then be connected to the control unit.
  • the control unit can control the respective working position of the dispensing edge depending on the test result of the test unit, which is transferred from the test unit to the control unit.
  • the control unit can then also control the collecting unit for defective labels.
  • control unit can also control the conveying device, ie in particular the different drive powers on the drive rollers.
