Definitions
- the invention relates to a device for printing on one or more objects movable in a feed direction, in particular labels, packaging, packaging sections, a tape strip or labels adhering to a carrier tape strip, with a print head and means for feeding the object to be printed to the print head.
- Such a device is known for example from DE 195 07 892 AI.
- a label tape which consists of a carrier tape strip with detachably attached labels, is passed between a thermal print head and a printing roller and printed using the thermal or thermal transfer method.
- the labels are then detached from the carrier tape by means of a separating device, in that the latter is guided around a dispensing edge.
- the printhead is fixed in the device and remains on the label or the carrier tape strip during printing in the thermal process during the entire transport and printing time.
- the print speed of a thermal printer is limited in terms of print quality. Furthermore, the wear of the thermal bar increases with increasing speed.
- the object of the present invention is to improve a device of the type mentioned at the outset in such a way that it offers a higher printing performance or labeling performance without reducing the print quality and / or increasing the thermal strip wear.
- the device according to the invention is essentially characterized in that the print head is provided with a drive by means of which the print head can be moved in the feed direction of the object to be printed and counter to the feed direction of the object ,
- the feed speed of the object to be printed can thus be increased without increasing the maximum print speed of the print head selected as a function of the desired print quality and the thermal strip life.
- the device according to the invention thus makes it possible to increase the feed speed of the object to be printed and thus the printing performance or labeling performance without reducing the printing quality and without increasing the wear on the thermal bar.
- the print head can be provided with a device by which the print head can be moved towards and away from the object to be printed. This configuration makes it possible to lift the printhead from the latter during printing pauses and during movement against the direction of advance of the object. This minimizes wear on the printhead due to abrasion.
- the drive by means of which the print head can be moved in the feed direction of the object to be printed and counter to the feed direction of the object, can be assigned a controller which controls this drive in such a way that the print head moves in the feed direction of the object has the same speed as the object to be printed or has a lower speed than the object to be printed.
- means for detecting the feed speed of the object to be printed can preferably be present, which send measurement signals proportional to the feed speed to the control, the control controlling the movement of the print head in dependence on the detected feed speed.
- a further advantageous embodiment of the device according to the invention is characterized in that the drive, by means of which the print head can be moved in the feed direction and counter to the feed direction of the strip, has a thrust crank mechanism or a piezo actuator.
- a slider crank gear particularly fast forward and forward can be reliably Realize backward pushing movements of the print head parallel to the feed direction of the ribbon. The same applies to a piezo actuator.
- a preferred embodiment of the device according to the invention also consists in that the print head is attached to a carrier mounted in a sliding guide, which also carries the drive by which the print head can be moved toward and away from the tape strip.
- This drive can have a cam disk or a circular disk with an eccentrically arranged axis of rotation, by means of which the print head can be brought into contact with the tape strip against the action of at least one spring element, preferably a coil spring.
- a plate-shaped counter bearing can be arranged opposite the print head, over which the back of the strip of tape slides during its advance.
- Fig. 1 is a schematic, not to scale
- Fig. 2 is a schematic, not to scale
- Fig. 1 shows a device for printing labels 2 adhering to a carrier tape strip 1.
- the labels 2 are attached to the tape strip 1 at a substantially uniform distance from one another.
- the tape strip 1 is unwound from a supply roll 3 and fed to a printing unit.
- the printing unit consists of a print head 4 in the form of a thermal print head and a plate-shaped, smooth surface counter bearing 5, over which the back of the strip 1 slides when it is fed.
- the print head 4 is designed in the form of a strip and extends transversely to the direction of advance of the tape strip 1 essentially over its width or the width of the labels.
- the print head 4 presses the labels 2 with sufficient force against the fixed plate-shaped counter bearing 5 and prints them, for example, in thermal or thermal transfer processes.
- a relatively sharp deflection in the form of a dispensing edge 6 is provided, on which the printed labels 2 can be detached from the carrier tape strip 1 in a manner known per se and removed through an opening in the housing of the device and applied to an object to be labeled.
- the carrier tape strip 1 is wound on the dispensing edge 6 on a winding roller 8 of a winding device driven by a stepping motor 7.
- the rotational speed of the stepping motor 7 or the take-up reel 8 is preferably infinitely adjustable.
- the thermal print head 4 is held on a plate-shaped carrier 9 which is mounted in a sliding guide 10.
- the schematically illustrated slide guide 10 can also be formed, for example, from roller bearings.
- the carrier 9 is provided with a drive by means of which it and thus the print head 4 can be moved parallel in the feed direction and counter to the feed direction of the strip 1. This is indicated by the double arrow.
- the drive comprises a stationary motor 11, preferably an electric motor, the motor shaft 12 of which drives a circular disk 13.
- the circular disk 13 has an eccentrically arranged pin 14 to which one end of an articulated rod 15 is articulated.
- the other end of the articulated rod 15 is articulated with a pin 16 attached to the carrier 9.
- the circular disk 13 with the eccentrically arranged pin 14, the articulated rod 15 articulated thereon and the support 9 mounted in a sliding guide with the articulated pin 16 attached thereto thus form a thrust crank mechanism.
- the distance between the axis of rotation of the motor shaft 12 and the center of the attached to the disc 13 The pivot pin 14 determines the stroke length of the thrust crank mechanism.
- the distance between the pivot pin 14 with respect to the axis of rotation of the motor shaft 12 can be adjusted and the pivot pin 14 n can be displaced and fixed accordingly on the circular disk 13 ,
- a control 17 is assigned to the motor 11 of the drive, which controls the drive in such a way that the print head 4 has the same speed as the carrier tape strip 1 or a lower speed than the carrier tape strip 1 when moving in the feed direction of the carrier tape strip 1.
- the reference numerals 18 and 19 denote a light-emitting transmitter diode and a light-emitting reception diode, which are part of a measuring device for detecting the feed speed of the carrier tape strip 1.
- the essentially evenly spaced labels 2 or other equally spaced markings on the carrier tape strip 1 interrupt the reception of the light emitted by the transmitter diode 18 at the receiving diode 19 when the tape strip is transparent.
- the receiving diode is to receive the light emitted by the transmitter diode due to light reflection on the labels 2 or on the label-free sections 20 of the carrier tape strip 1, it is - in contrast to the illustration in the drawing - together with the transmitter diode 18 on the label 2 facing Side of the carrier tape strip 1 arranged.
- other means can also be used to detect the feed speed of the carrier tape strip, for example a dynamo rolling on the carrier tape strip or the like.
- the receiving diode 19 or the dynamo delivers measurement signals which are proportional to the feed speed of the carrier tape strip 1. These signals are sent to the measuring and control device 17, which controls the rotational speed of the motor shaft 12 and thus the translational movement of the carrier 9 and the print head 4 as a function of the detected feed speed of the carrier tape strip 1.
- the carrier 9 is provided with a device through which the print head 4 on the carrier tape strip 1 towards and away from the carrier tape strip 1 can be moved.
- This device is also connected to the measuring and control device 17 via a signal line 21 and comprises an electric motor 26, preferably a stepper motor, and a circular disk 27 with an eccentrically arranged axis of rotation. 28 with a bracket 9 formed on the support for the motor 26 is designated.
- the carrier 9 is shown in the drawing in longitudinal section.
- the print head 4 is provided with parallel rods 29, 30 which are guided in slide bearings formed in the carrier 9. The upper ends of the rods 29, 30 are connected to one another by a cross rod 31.
- a spring element 32 in the form of a helical spring is arranged between the carrier and the crossbar and moves the print head 4 away from the strip of tape.
- the print head 4 can be brought into contact with the carrier tape stiffener 1 or the label 2 to be printed against the action of the coil spring 32.
- the measuring and control device 17 controls the drives in such a way that the print head 4, when moving in the feed direction of the carrier tape strip 1, bears against a label 2 that is to be adhered to the carrier tape strip and, when moving against the feed direction of the tape strip 1, at a distance from the carrier tape strip or the labels 2 attached to it is moved.
- the exemplary embodiment shown in FIG. 2 differs from the exemplary embodiment according to FIG. 1 only in that instead of the electric motor 26, the eccentrically mounted circular disc 27, the holder 28, the parallel guide formed from the rods 29, 30 and the transverse rod 31 and the Spring element 32 at least one piezo actuator 33 is used to raise and lower the print head 4.
- the thermal print head 4 is fastened in FIG. 2 to at least one piezo actuator 33, which in turn is held on the underside of the plate-shaped carrier 9.
- the carrier 9 is in turn mounted in a sliding guide 10.
- a roller bearing can also be used.
- the embodiment of the invention is not restricted to the exemplary embodiments described above. Rather, several variants are conceivable which, even with a fundamentally different construction, differ from the inventive idea as disclosed in the claims is make use of.
- the invention is not limited to the printing of labels adhering to a carrier tape strip.
