Hand-held labeling machine

The invention relates to a hand-held labeling device according to the preamble of claim 1.

In a device of this type known from DE-PS 23 45 249, the printing of the self-adhesive labels takes place in a printing zone, which is two label lengths away from the dispensing edge against the direction of advance of the carrier tape. this means that the self-adhesive label, which is brought into the dispensing position in one work cycle, in which it is on a Object can be attached, has already been printed in the previous work cycle. After applying the label an object with an imprint is therefore already located in the device before the start of the next work cycle provided label. If the imprint to be applied is changed, this label must be removed from the device, so that only labels with the changed imprint are attached to objects. As it is with the imprints the labels usually refer to sales prices, the presence of such is still indicated by a

13Ö067 / 0O1

The old price label is highly undesirable as it leads to incorrect pricing of items can occur if the label that has already been printed on is forgotten to remove from the device after a price change.

The invention is based on the object of designing a device of the type described at the outset so that also in larger distance between the dispensing edge and the print zone after completion of a work cycle no already printed, but the self-adhesive label that has not yet been donated is present in the device.

According to the invention, this task is carried out with the characteristics of claim 1 specified features solved. In the device according to the invention, the carrier tape is attached to it adhesive self-adhesive labels transported in each work cycle by performing a so-called pilgrim step movement, which means that the label on the dispensing edge is first brought back to the print zone, whereupon it then goes back to the dispensing edge after the printing process and beyond that up to the dispensing position in the forward direction is transported. This means that only one self-adhesive label is printed in each work cycle, which is then also that label is that is brought into the dispensing position in the same work cycle and on an object can be attached. If the imprint to be produced on the label is changed, the inventive concept contributes Design of the hand-held labeling device, the next label dispensed has the new print. The removal Label already provided with the old print in previous work cycles is therefore unnecessary, so that there is no longer any risk of incorrectly printed labels being attached.

Advantageous further developments of the invention are characterized in the subclaims.

The invention will now be explained by way of example with reference to the drawing. Show it:

Fig. 1 is a side view of the device according to the invention,

2 shows a schematic side view of the drive elements essential for the transport of the carrier tape in the basic position,

Fig. 3 is the same view as in Fig. 1, the drive elements, however, the position directly take before the start of the synchronous carrier tape transport in the return direction,

FIG. 4 shows a section through the transport roller along the line 3-3 of FIG. 2,

FIG. 5 is a partially sectioned view of the transport roller with that indicated by the arrows A and B. FIG Direction of view with a position of the transport roller as in Fig. 2 and

FIG. 6 is the same view as in FIG. 4, but with the transport roller assumes the position of FIG.

In Fig. 1, a hand-held labeling device 1 is shown, with the help of which self-adhesive labels adhering to a carrier tape can be printed and issued for attachment to an object. The device 1 has an operating lever 2 on, the one firmly attached to the device housing

13G067 / 0U1

connected axis 4 between the rest position shown in FIG and a working position in which it is pulled against the handle 5 fixed to the housing, is pivotably mounted.

A shaft 6 attached to the top of the housing is used the inclusion of a carrier tape supply roll 7. From the supply roll 7, the carrier tape arrives with its adhering to it Self-adhesive labels for a dispensing edge located at the bottom left in the illustration of FIG. 1, on which, in each work cycle, that is, when the operating lever 2 is pivoted from the rest position into the working position and back again in the rest position, a self-adhesive label is peeled off the carrier tape, and comes into a dispensing position in which it is on an object can be attached. In Fig. 1, a self-adhesive label 8 is shown in the dispensing position.

The parts of the hand-held labeling device 1 which are required for the transport of the carrier tape 17 are shown schematically in FIG will. The operating lever 2, which is pivotable about the axis 4 and which has a toothed segment 9, is also shown schematically has, with the help of which its pivoting movement can be used to drive the actual transport elements can. The toothed segment 9 is in engagement with a pinion 10 which is seated in a rotationally fixed manner on an axle 11. With this axis 11 is also a gear 12 connected in a rotationally fixed manner, which is a tooth segment rigidly connected to the type wheel 13 of a rotary printing unit 14 combs. The type wheel 13 and the tooth segment 14 are rotatably mounted about an axis 14a.

The type wheel 13 has a printing segment 15 in which the types of printing are located in a printing zone 16 on a Self-adhesive label 8 should produce an imprint on the carrier tape 17. The print types can be numbers, Letters or, if a barcode is to be printed,

130067/04 * 1

be line-like types with different widths. The type wheel 13 is composed of several discs, each provided with printing types on their circumferential surface are. The individual printing types can be moved to the printing segment 15 by rotating the individual disks about the axis 14a so that printing types of adjacent disks can be combined in any way on this printing segment.

The carrier tape 17 with the self-adhesive labels 8 adhering to it is fed from the supply roll 7 via a spring plate 18, which holds the carrier tape 17 taut, is guided to a roller 19 which it under the action of a spring 20 against the circumferential surface of the type wheel 13 presses. In the range of the type number, which adjoins the pressure segment 15 counterclockwise, a cover plate 21 is attached so that the roll 19, the carrier tape 17 with the self-adhesive labels 8 not directly against the circumferential surface of the character wheel, but against that attached to the mentioned area of this circumferential surface Cover plate 21 presses.

The carrier tape 17 is further between a pressure roller 22 which is in engagement with the type wheel via a tooth connection on the type wheel 13, and then arrives at a dispensing edge 23. When the carrier tape 17 is in the direction indicated by the arrow 24 Forward direction is drawn around the dispensing edge 23, detach the self-adhesive labels 8 from the carrier tape 17, so that they get into the dispensing position. A self-adhesive label 8 located in the dispensing position is shown in dashed lines in FIG shown.

The carrier tape 17 then runs on to a transport roller 25, around which there is a relatively large angle of wrap is shown around. The transport roller 25 is provided with projections which are inserted into slot-shaped recesses in the carrier tape 17

130087/0431

intervention. The slots in the carrier tape 17 are arranged at a distance from one another which is the length of a self-adhesive label 8 corresponds. The projections 26 on the transport roller 25 are attached exactly at the distance of the slots in the carrier tape, so that the carrier tape 17 in the course of the individual Operating cycles of the device assumes a well-defined position when the projections 26 in engagement with the slots in the carrier tape 17 stand.

So that the carrier tape 17 is held securely in engagement with the peripheral surface of the transport roller 25, worm springs are used provided, which are guided around rollers 28, 29, 30 and 31 and wrap around the transport roller 25 as well as the carrier tape 17. The carrier tape 17 is between the peripheral surface of the Transport roller 25 and the worm springs 27 passed through.

The transport roller 25 is assigned a backstop 32, which is firmly connected to the device housing 3 and occupies the position shown in FIGS. The backstop 32 includes a return locking member 33, which consists of a spring-loaded ball. This return locking member 33 cooperates with ratchet teeth 34 which are attached to an inwardly directed circumferential surface of the transport roller 25. As can be seen, the backstop 32 allows one Rotation of the transport roller 25 counterclockwise, while it rotates clockwise due to the ratchet teeth 34 opposes a resistance. The transport roller 25 can only be rotated counterclockwise when the Return locking member 33 exerted spring force is overcome. The return locking member 33 then practically jumps over the locking tooth 34 so that the transport roller 25 is free can continue to rotate until the next locking tooth 34 comes into contact with the return locking member 33.

130ÖS7 / 0431

A drive wheel 36, which is shown in FIG is shown in section. If it is taken into account that in Figures 2 and 3, the transport roller 25 in the direction of the 4, the drive wheel 36 is seated in the representations of FIGS. 2 and 3 the back of the transport roller 25.

The drive wheel 36 can be rotated via the gear wheel 12 and the toothed segment 9 by pivoting the operating lever 2 will. The connection between the drive wheel 36 and the transport roller 25 is formed by a directional lock, which contains the lead pawls rigidly connected to the drive wheel 36, with lead ratchet teeth 39 on the transport roller 25 work together. This directional lock allows the transport roller 25 to be seen while the drive wheel 36 is held of Fig. 2 and Fig. 3 to rotate clockwise, while there is counterclockwise rotation prevented. It should be noted here that these directions of rotation are reversed in the views of FIGS. 5 and 6, since in In these figures, the transport roller is viewed from the rear with respect to FIGS. 2 and 3. In the figures and FIG. 6, the directional lock thus permits a relative rotation of the transport roller 25 with respect to the drive wheel 36 counterclockwise while preventing clockwise rotation.

It can be seen from FIGS. 5 and 6 that not only the forward pawls 38 are rigidly connected to the drive wheel, but also also a return pawl 40 which cooperates with drive teeth 41 on an inner peripheral surface of the transport roller 25. As shown in FIG. 6, the transport roller 25 is driven clockwise by means of the return pawl 40 when the Return pawl 40 in the course of the rotation of the drive wheel encounters a reverse drive tooth 41.

130067/0431

303013;

According to FIG. 4, the transport roller 25 is seated between two walls 42 and 43 which are firmly connected to the device housing 3. An opening 44 is made in the wall 42, the circumference of which, with the exception of a limited circumferential area, is a circle about the axis 35 of the transport roller 25 is described. In Figures 5 and 6 it can be seen that the circumference of the opening deviates from the circular shape in its lower circumferential region and forms a control surface 45, the distance between which from the axis is less than in the remaining areas of the opening circumference. The function of this control surface 45 can be seen when considering 4 in connection with FIGS. 5 and 6 recognize. According to Fig. 4, the return pawl 40 protrudes in the lateral direction out of the right-hand end face of the transport roller. When the drive wheel 36 is the one shown in FIG Assumes position, is supported on the end face of the transport roller 25 protruding portion of the return pawl on the control surface 45, so that the return pawl 40 is not in engagement with a return drive tooth 41 on the transport roller 25 can come. Only when the drive wheel and the return pawl 40 rigidly connected to it have rotated that far have that the return pawl 40 is no longer supported by the control surface 45, the return pawl act on a drive tooth 41 on the transport roller 25. In Fig. 6, such a position of the drive wheel 36 is shown. With a further rotation of the drive wheel 36 drives the return pawl 40 by acting on the return drive tooth 41 the transport roller 25 in the view of FIG. 6 in a clockwise direction.

After the drive elements necessary for the carrier tape transport, their mutual position and their individual effects have been described, the description now follows Functional sequences that occur in the course of a work cycle, i.e. when the operating lever is pivoted from the rest position to the working position and back to the rest position.

130Ό & 7/0431

At the beginning of a work cycle, the drive elements assume the basic positions shown in FIG. The basic positions the forward pawl 38 and the return pawl 40 are shown in FIG. As soon as the control lever 2 against the handle 5 is pulled, the toothed segment 9 moves counterclockwise about the axis 4, so that the Pinion 10, which is in engagement with toothed segment 9, rotates clockwise in the view of FIG. 2. In the the same way rotates non-rotatably with the axis 11 of the Pinion connected gear 12 clockwise, so that thereby also the type wheel 13 by means of the rigidly connected to it Tooth segment 14 is rotated counterclockwise.

The gear 12 also rotates the drive wheel 36 in the illustration of FIG. 2 counterclockwise (in the illustration 5 clockwise), with the result that the forward pawls 38 in the view of FIG. 5 clockwise of the forward ratchet teeth 39 begin to remove. Since that Carrier tape 17 by frictional entrainment due to the action between the roller 19 and the cover plate attached to the circumference of the character wheel 21 in the return direction, that is, in the direction of the carrier tape supply roll 7 is pulled, this pulling force also moves the transport roller 25 in FIG. 2 counterclockwise. this means in practice that the transport roller 25 follows the rotation of the drive wheel 36. The relative position of the forward pawls 38 and the drive wheel 36 to the transport roller 25 does not change as a result. The transport roller 25 can move of the drive wheel 36, however, only follow until the return locking member 33 is in contact with the next locking tooth 34 comes. In the illustrated embodiment, the backward movement of the carrier tape 17 takes place until the edge 46 of the self-adhesive label 8 adjoining the dispensing edge 23 to the print zone, which is at the front in the return direction 16 has been withdrawn. In the case of the proportions indicated in FIG. 2, the backward direction is Transport distance in this initial phase about half a label length.

13Ö0S7 / 0431

The type wheel 13 also rotates the pressure roller 22 via a tooth connection, which has a circumferential section 47 with a larger Has a radius and a peripheral portion 48 with a smaller radius. The larger radius is dimensioned in such a way that that it is exactly the same as the distance between the axis of rotation 49 of the pressure roller 22 from the circumference of the type wheel. The axis of rotation 49 the pressure roller 22 is loaded with a spring, not shown, in the direction of the type wheel when the peripheral portion is in engagement with the character wheel circumference. However, the spring is ineffective when the peripheral portion 48 is smaller Radius is in opposition to the type wheel 13, so that In this case, the carrier tape 17 can move freely between the pressure roller 22 and the circumference of the character wheel. Fig. 2 shows that the carrier tape immediately after the start of the rotation of the type wheel 13 counterclockwise and thus after Start of the rotation of the pressure roller 22 in the clockwise direction pulled freely between the pressure roller 22 and the type wheel 13 can be.

After the return locking member 33 is in contact with the locking tooth has come, further rotation of the transport roller is prevented. The friction between the roller 19, the carrier tape 17 and the cover plate 21 on the type wheel 13 generated drag force, which acts as a tensile force on the carrier tape 17 in the direction of the carrier tape supply roll 7 is not large enough to the transport roller 25 overcoming the return locking member 33 to move the locking force exerted over the locking tooth 34. It thus occurs with continued rotation of the type wheel 13 slipping between the cover plate 12 and the carrier tape 17 with the self-adhesive labels located thereon 8 so that the carrier tape is no longer withdrawn.

130087/0431

In this operating phase, in which the carrier tape is held in place by the transport roller 25 stands still, move the type wheel 13 and thus also the pressure roller 22 driven by it to -the one shown in FIG. 3 Positions further. The pressure segment 15 thereby reaches a position adjoining the pressure zone 16, and also the pressure roller 22 begins to press the carrier tape against the type wheel, since its peripheral portion 47 is now in engagement reached with the type wheel. The drive wheel 36 also continues to move in this operating phase, so that the return pawl moves 40 is moved relative to the stationary transport roller 25 into the position shown in FIG. 6. Fig. 6 shows the Return pawl 40 in the position in which it just comes into contact with a return drive tooth 41. If now that Drive wheel 36 is rotated further due to the further movement of the operating lever 2 by the gear wheel 12 (in Fig. 3 opposite clockwise and in Fig. 6 clockwise), then the transport roller 25 of the return pawl 40 due to the Action on the return drive tooth 41 overcoming that exerted by the return catch member 33 on the catch tooth 34 Locking force further rotated, which has the consequence that the Carrier tape 17 now again as in the initial phase in FIG Can move reverse direction. At the same time, the carrier tape 17 with the self-adhesive label located on it is thereby from the peripheral portion 4 7 of the pressure roller 22 against the type wheel pressed so that in the pressure zone 16 the types present in the pressure segment 15 on the self-adhesive label 8 to Generating an imprint roll off. Since the pressure roller 22 is driven by the type wheel 13 via a tooth connection, takes place the now taking place movement of the carrier tape 17 in the return direction exactly synchronous with the movement of the type wheel 13 and the pressure roller 22, because the carrier tape 17 is carried along when the peripheral surfaces are rolled over. From the beginning of the renewed transport of the carrier tape 17 in the return direction

130087/0431

on the carrier tape 17 is still so far in the return direction moves until the entire printing segment 15 has rolled on the self-adhesive label 8 in the printing zone 16. Of the The operating lever 2 has then reached its working position in which it is pulled completely against the handle 5. In the illustrated In the exemplary embodiment, the carrier tape 17 has thus a total of approximately one and a half label lengths in the return direction emotional.

If now the operating lever 2 is released, and under the action of an acting between it and the handle 5 When the spring returns to its rest position shown in FIG. 1, the directions of rotation described rotate of all drive elements. In detail, this means that the toothed segment 9 is now about the axis 4 in a clockwise direction rotates, which rotates the pinion 10 and the gear 12 counterclockwise. Accordingly, the type wheel 13 also moves clockwise, so that this the pressure roller 22 drives counterclockwise. The drive wheel 36 rotates in the view of Figures 2 and clockwise, so that it is due to the engagement of the forward pawls 38 on the forward ratchet teeth 39, the transport roller 25 takes away. The backstop 32 is no obstacle for such a rotation of the transport roller 25, since the return locking member 33, the locking teeth 34 in this direction of rotation the transport roller 25 can easily overrun.

At the beginning of the clockwise rotation of the type wheel 13, the printing segment 15 rolls again on the self-adhesive label 8, as this moves through again between the type wheel and the pressure roller 22.

The transmission ratios between the toothed segment 9, the pinion 10, the gear 12 and the drive wheel 36 are selected so that that the conveyor belt 17 in the course of the return of the

150067/0431

Operating lever 2 from the working position to the rest position by a distance in the forward direction indicated by the arrow 24 is transported, which is equal to the distance of the dispensing edge 23 from the print zone 16 plus a label length is. Because of this dimensioning, it is achieved that the label 8, which is located before the start of the work cycle located immediately behind the dispensing edge 23, after the end of the work cycle, the indicated by the dashed line Label 8 assumes indicated dispensing position, in which it is detached from the carrier tape 17 and attached to an object can be.

The different transport in the return direction and in Forward direction is achieved in that the return device slips through in a defined manner with respect to the carrier tape, so that not the entire pivoting movement of the operating lever 2 from the rest position into the working position in a transport movement of the carrier tape in the return direction implements. The opposite direction of movement of the operating lever 2 from the working position to the rest position on the other hand, is completely converted against a transport movement of the carrier tape in the forward direction. In order to the difference between the transport in the return direction and the transport in the forward direction of exactly one label length corresponds, the drive wheel 36 is after the standstill of the transport roller 25 relative to this until the engagement of the Return pawl 40 on the return drive tooth 41 at an angle rotated further, which corresponds to an arc the length of a self-adhesive label on the circumference of the transport roller 25.

In the basic position of the hand-held labeling device shown in FIG. 2 1 self-adhesive label 8 located directly on the dispensing edge 23 has not yet been printed because it as the above description of the operational sequence shows, first

130087/0431

303013

is printed in the course of the backward transport movement of a work cycle when it arrives in the printing zone 16. The print to be produced on the self-adhesive label 8 can therefore be changed easily without the There is a risk that a label still provided with an unchanged print will be attached to an object which should already have a label with a new print. In the device described, it is therefore not possible that a Label is issued that bears an imprint that is not the type set on the printing segment of the type wheel is equivalent to.
