Description

The invention relates to a dispensing device.

In labeling devices, a label tape is moved either continuously or clocked and usually performed around a sharp dispensing edge, so that the labels solve at the dispensing edge of the carrier tape of the label tape and glued onto a product to be labeled. Today's labeling devices use speeds of, for example, 150 m / min in clocked operation, in which the label tape is stopped between each dispensing operation.

There are cases where a label should not be donated because it is faulty or badly printed, for example. In such cases, the label may either be glued onto something else, such as an additional tape moved in place of the product to the dispensing edge, or it may remain on the carrier tape, not be donated to the dispensing edge. For this purpose, the maximum curvature that the label tape undergoes on its way through the labeling device must be gentler or, in mathematical terms, lower than in the case of the sharp dispensing edge.

The DE 10 2011 082 450 A1 shows a device for selectively releasing arranged on a carrier tape labels. A diverter has a dispensing edge that allows labels to be dispensed. If a label is to remain on the carrier tape, the dispensing edge is moved back and the label web for the label tape has a lower curvature.

The US 6,092,945 A shows a printer that can print both single pages and a label tape.

The US 6,068,419 A shows a label printer with a peel edge.

The JP 2017-105519 A shows a label transport device with a holding element.

The DE 196 06 014 A1 shows a device for producing a label roll.

It is therefore an object of the invention to provide a new dispensing device.

The object is solved by the subject matter of claim 1.

A dispenser for dispensing labels from a label tape has a tape guide and a diverter. The tape guiding element has a depression and a dispensing edge assigned to the depression. The deflecting member is movable relative to the dispensing edge in a first position and in a second position. The deflecting part is designed to move during a movement of the label strip in a predetermined direction ( 96 ) in the first position, a contact of the deflecting part with the label tape and a movement of the label tape ( 90 ) from the deflection part ( 42 ) to the dispensing edge ( 26 ) and to cause a deflection of the label strip at the dispensing edge with a first dispensing edge deflection angle to effect a dispensing of a label at the dispensing edge, and to allow in the second position a course of the label strip, in which no dispensing of a label the donation edge takes place.

Such a dispensing device enables dispensing of a label by moving the diverter member to the first position relative to the dispensing edge. The dispensing edge can remain stationary, but it can also be moved.

According to a preferred embodiment, the deflection part is designed to effect no deflection of the label strip at the dispensing edge in the second position. The label tape can just run past the dispensing edge or have no contact with the dispensing edge if you do not want to donate.

According to a preferred embodiment, the deflection part is designed to effect a deflection at the dispensing edge in the second position with a second dispensing edge deflection angle, which second dispensing edge deflection angle is smaller than the first dispensing edge deflection angle, to dispensing a label at the dispensing edge to prevent. Due to the deflection at the dispensing edge, there is already a contact with the label tape, and as a result, during a relative movement of the deflecting member relative to the dispensing edge, impacts on the label tape are avoided. In addition, the switching can possibly be faster.

According to a preferred embodiment, the deflecting part is designed to have no contact with the label tape in the second position. In the second position, no deflection is needed by the diverter, and the lack of contact reduces friction and reduces the risk of contamination of the diverter by side-release of pressure sensitive adhesive.

According to a preferred embodiment, the deflecting member is adapted to allow in the first position, a contact of the deflecting member with the label tape in the recess. The deflecting part can thus be located at least partially in the recess, and the label tape runs along a label web, which runs partially through the depression. This allows an advantageous enlargement of the deflection angle at the dispensing edge.

According to a preferred embodiment, the tape guide element is adapted to allow in the first position of the deflection before and after the recess contact with the label tape.

According to a preferred embodiment, the deflection part has a contact region, which contact region is designed to be in contact with the label strip in the first position, which contact region has a first region and a second region, which second region is closer to the first position Donor edge is considered the first region, and which first region is less curved than the second region. This design makes it possible to get close to the diverter with the diverter. In addition, the recess can be made shallower than, for example, a round cross-section.

According to a preferred embodiment, the deflection part is designed as a rod, as a roller or as a cylinder. Rods have an elongated extension and can have different cross sections. Rollers can rotate with the label tape and lead advantageously to a lower friction. Cylinders have a round cross-section on the outside and work as well.

According to a preferred embodiment, the deflecting part is arranged in the first position further inside in the recess than in the second position. This is an advantageous possibility for changing the band profile and the donor edge deflection angle.

According to a preferred embodiment, the deflection part is arranged closer to the dispensing edge in the first position than in the second position. As a result, the feed angle of the label tape is changed to the dispensing edge and increases the dispensing edge deflection angle.

According to a preferred embodiment, the dispensing device is designed to curve in the first position, a first side of the label strip, which is associated with the deflecting part, concave at least partially concave on the deflecting part and at least partially convexly curved at the dispensing edge. Due to the concave curvature, the label is also curved, and in the subsequent convex curvature in the opposite direction, the label dissolves easier due to the Vorkrümmung from the label tape.

According to a preferred embodiment, the recess is formed as a groove and extends transversely to the tape guiding direction. The formation of a groove is advantageous, as this can be produced in a simple manner a recess, and it is easily achievable a predetermined relative position to the dispensing edge.

According to a preferred embodiment, the depression has a depth which is at least 0.5 mm, more preferably at least 2 mm, and particularly preferably at least 3 mm. So it is possible even at shallow depths donations.

According to a preferred embodiment, the band guide element has a deflection edge, which deflection edge is designed to allow a deflection of the label strip without detachment of a label on the deflection edge. Such a deflection is advantageous in order to enable a return of the label strip to the labeler, or to have space in the area in front of the deflection edge for an application.

According to a preferred embodiment, the position of the deflection edge remains unchanged relative to the dispensing edge in a change of the deflection from the first position to the second position. The use of the deflecting part allows a design of the dispensing device such that the deflecting edge does not have to be moved relative to the dispensing edge. As a result, a very low mechanical tolerance and a simple structure are possible.

According to a preferred embodiment, channels have channel openings in the region of the deflection edge in order to allow a supply of compressed air in the region between the deflection edge and the label strip. Through the channel openings in the region of the deflection edge, the friction between the label strip and the deflecting edge can be greatly reduced, and this allows rapid acceleration of the label strip.

According to a preferred embodiment, the surface of the deflection edge is at least partially microporous. The microporous formation reduces the contact area between the label strip and the deflecting edge and thereby leads to a reduction of the friction.

According to a preferred embodiment, the dispensing edge is at least partially rounded. Experiments have shown that an angular dispensing edge at high accelerations can lead to a demolition of the label tape at the dispensing edge. The provision of a rounding is therefore advantageous.

According to a preferred embodiment, a guide element is designed to guide the label donated at the dispensing edge in a predetermined direction. The provision of the guide element allows adaptation of the direction in which the label is dispensed, and this direction can be adapted to the requirements of the application.

According to a preferred embodiment, the guide element has a transport element in order to secure the label donated at the dispensing edge and move it to another location. For some applications, it is advantageous to supply the donated label via such a transport element to the product to be labeled. The transport element can be advantageously positioned for receiving the label in the region of the dispensing edge.

According to a preferred embodiment, a change of the deflection part from the first position to the second position is to be made possible while the label tape is in motion. In particular, at high labeling speeds, it is advantageous to be able to perform a corresponding change in a band movement.

According to a preferred embodiment, a change of the deflecting part from the second position to the first position is to be made possible while the label tape is in motion. In particular, at high labeling speeds, it is advantageous to be able to perform a corresponding change in a band movement.

According to a preferred embodiment, the dispensing device is adapted, upon contact of the diverter with a first label in the first position, to allow the diverter to change from the first position to the second position, dispensing the first label to the dispensing edge Label subsequent label but not donated to the dispensing edge. The dispensing device thus allows a change to the second position, while the deflection still has contact with the first label.

According to a preferred embodiment, the dispensing device has a position change device, which is designed to allow a controllable movement of the deflection part relative to the dispensing edge between the first position and the second position. The relative movement of the deflection part is preferably carried out by a controllable position change device in order to enable a quick change.

According to a preferred embodiment, the position changing device on a rotary arm and a bearing point, which rotary arm is connected to the deflecting part and rotatably supported at the bearing point to allow rotational movement of the rotary arm with the deflecting between the first position and the second position. The use of a rotary arm enables a slender construction of the dispensing device in the area of the dispensing edge, since the position changing device does not have to be arranged in the region of the dispensing edge or the depression.

According to a preferred embodiment, the bearing point is arranged on the side facing away from the deflecting side of the recess. This arrangement of the bearing causes the deflection is moved closer to the dispensing edge when screwing into the recess by the circular path, as in an arrangement of the bearing on the open side of the recess.

According to a preferred embodiment, the position change device is assigned a spring element, which spring element acts on the position change device in a predetermined direction with a force such that the deflection part is acted upon by the spring element in the direction from the first position to the second position with a force. The use of a spring element makes it easier to use only one type of actuator, if it can not act in two directions. On the other hand, the spring element facilitates a fail-safe design of the dispensing device in the event that the actuator does not work, because then preferably no donations of labels takes place.

• - einen Wechsel von der ersten Position zur zweiten Position, oder
• - einen Wechsel von der zweiten Position zur ersten Position, oder
• - einen Wechsel von der ersten Position zur zweiten Position und einen Wechsel von der zweiten Position zur ersten Position

zu ermöglichen.According to a preferred embodiment of the position change device is associated with an actuator, which is designed to be controllable

• a change from the first position to the second position, or
• a change from the second position to the first position, or
• - A change from the first position to the second position and a change from the second position to the first position

to enable.

So different types of actuators can be used. Simple actuators allow only one change, other actuators both changes.

The actuator is preferably a pneumatic muscle. Pneumatic muscles allow a fast response time and a great force during contraction. This leads to a very reliable dispensing device.

According to a preferred embodiment, the actuator is connected on the one hand to the deflection part via a first rotary joint and on the other hand to the belt guide element via a second rotary joint. This embodiment is particularly advantageous in embodiments in which the deflecting member is moved via a rotational movement. In this case, non-linear movements occur between the deflection part and the strap guide element, and the relative movements are compensated by the rotary joints.

According to a preferred embodiment, the position change device is connected laterally from the provided for the label strip label web with the deflection. As a result, the position change device on the one hand in the way for the label tape course, and on the other hand, the dispenser can be easily adapted to different label bandwidths.

According to a preferred embodiment, the position change device is connected to the deflecting part on two opposite sides of the deflecting part. This allows good access to the region of the deflecting part, which is arranged between the two opposite sides.

According to a preferred embodiment, the tape guide element comprises a plate in which plate the recess is provided, wherein the plate is adapted to allow a guidance of the label tape along the plate. The design as a plate allows very advantageous formation of the recess and a stable construction.

According to a preferred embodiment, the plate forms the dispensing edge and preferably also the deflection edge. The plate can thus advantageously form both the depression and the dispensing edge. In addition, if necessary, the deflection can be formed by the plate.

According to a preferred embodiment, the plate has a thickness in the range 5 mm to 35 mm, preferably in the range 7 mm to 20 mm. These thicknesses have proved to be advantageous, since the plate is on the one hand comparatively thin and therefore facilitates use in the application. On the other hand, the plate is stable enough.

According to a preferred embodiment, the plate has, at least in sections, a wear protection layer, in particular a hard-enamel layer. Experiments have shown that the plate is subject to abrasion by the label tape and can be permanently destroyed. The use of a wear protection layer in this area allows a longer service life.

1 shows an example of a labeling device 10 with a labeller 11 a liquidator 12 , a rewinder 13 and a dispenser 20 , which can also be referred to as a detachment device.

At the unwind 12 is a role 111 with label tape 90 arranged. The label tape 90 has a carrier tape 91 and labels arranged on it 92 , The label tape 90 runs from the label tape roll 111 via a brake device 15 to the dispenser 20 , The brake device 15 For example, is a resilient sheet, which is the label tape 90 presses against a plate.

The label tape 90 in the exemplary embodiment is the dispensing device 20 led around. The dispenser 20 allows detachment of a label 92 from the carrier tape 91 and attaching the detached label 92 on an object to be labeled 19 which is attached to the dispenser 20 passed by.

When considering the curvature, it is necessary for the dispensing of a label that the label tape is clearly deflected over a small distance, for example by 50 °, 60 ° or 120 ° in the degree. A deflection of 3 °, for example, in conventional label tapes does not lead to a detachment of a label 92 even if a corresponding kink occurs on a very small distance.

This after donating the label 92 from the label tape 90 remaining carrier tape 91 is exemplified returned to the labeler 11 , and on the labeller 11 is a drive roller 16 provided, which is the carrier tape 91 drives. Usually, a - not shown - pressure roller is provided which the label tape against the drive roller 16 pressed. Then the carrier tape runs 91 continue to the rewinder 13 and is wound up there. By doing that, the label tape 90 or carrier tape 91 through the drive roller 16 over the dispenser 20 is pulled and on the feed side by the braking device 15 is braked, it is taut or under tension on the dispenser 20 on. An example is a printer 18 provided the label tape 90 or the labels 92 can print. After the printer 18 is a verification device 17 provided, for example, a camera or a code reader (code checker). The verification device 17 For example, check the pressure of the printer 18 on the label. If there is an error, the label in question will be 92 not donated but diverted.

For labeling devices 10 As a rule, there is a direction in which the label tape passes through the labeling device 10 passes through because the label tape 90 due to the lack of dimensional stability only pulled and can not be pushed. Also the donation of the label tape 90 usually takes place only in one direction. Therefore, positions can be said to be before or after another position.

In operation, the label tape 90 either continuously driven, or a clocked operation can be performed, in which between each dispensing the label tape 90 stops briefly until the next item to be labeled 19 at the dispenser 20 is arranged. Today's high performance labeling machine 11 donate to the dispenser 20 labels 92 at a label tape speed of, for example, 150 m / min in clocked mode, and very high speeds and accelerations are possible.

In practice, it happens that labels 92 not to be donated. This may, for example, be the case if the printer 18 has a malfunction or a label 92 was determined by a control device as faulty, for example, a label 92 with an RFID system (RFID = radio-frequency identification). In such a case, the label may 92 either donated to another object or a band and thus from the dispenser 20 be carried away, or it may be on the carrier tape 91 remain with this on the rewinder 13 be wound up. The latter possibility has the advantage that on the wound carrier roll on the rewinder 13 If necessary, it can be checked whether the corresponding labels 92 available. In particular, in the labeling of drugs, it happens that such a check must be made and no labels 92 may disappear.

Relative movement between deflecting and tape guide

2 to 5 show a schematic representation of the structure and operation of the dispenser 20 , The tape guiding direction 96 , in which the label tape moves along the predetermined course is drawn.

2 shows the dispenser 20 which is a tape guide element 22 and a diverter 42 having. The tape guiding element 22 has a recess 24 and one of the deepening 24 assigned dispensing edge 26 on. The position of the deflector 42 relative to the donation edge 26 is changeable, and in the representation is the deflection 42 in a first position P1 relative to the donation edge 26 , The relative movement between the deflection 42 and the donor edge 26 takes place preferably via a movement of the deflection 42 , where the position of the dispensing edge 26 relative to the labeler 11 (see. 1 ) is not moved, so is stationary. Alternatively, however, a movement of the donor edge with the same effect 26 at stationary deflection 42 possible, or it can both the deflector 42 as well as the donation edge 26 be moved, with a resulting relative movement.

The tape guiding direction 96 is drawn. The depression is preferred 24 formed as a groove which transverse to the tape guide direction 96 runs. Such a groove can be mechanically accurate in the tape guide 22 be provided, and it therefore leads to lower tolerances.

In the first position P1 has the deflection part 42 Contact with the label tape 90 , and it allows a deflection of the label tape 90 at the donation edge 26 , Through this deflection of the label tape 90 at the donation edge 26 can a label 92 at the donation edge 26 from the carrier tape 91 be solved, and the donated label 92 Can on an object to be labeled 19 (see. 1 ) are donated.

5 shows the donor edge deflection angle 29A who is in the position P1 from 2 occurs. The donor edge deflection angle 29A is in the exemplary embodiment just under 90 °. The label tape 90 So it runs in a predetermined feed angle on the dispensing edge 26 to and is there with the deflection angle 29A diverted. However, this redirection makes the label 29B , which is usually slightly stiffer than the carrier tape 92 is not with, and it detaches itself from the carrier tape 92 ,

3 shows the dispenser 20 from 2 , where the deflecting part 42 relative to the donation edge 26 in a second position P2 located. For this purpose, the deflection 42 for example via a position change device 46 from the first position P1 in the second position P2 to be moved. The deflection part 42 has in the second position P2 a greater distance from the dispensing edge 26 , and it is in the orientation of the dispenser 20 from 3 moved to the left. The deflection part 42 is in the first position P1 closer to the donor edge 26 than in the second position P2 , The deflection part 42 could change from the first position P1 to the second position P2 in addition, be moved slightly downwards or upwards.

The position change device 46 is designed to be a controllable movement of the deflection 42 relative to the donation edge 26 between the first position P1 and the second position P2 to enable.

By changing the position of the deflection 42 relative to the donation edge 26 the angle changes with which the label tape 90 on the donation edge 26 tapers. The donor edge deflection angle in the second position P2 is indicated at 29B and is smaller than the donor edge deflection angle 29A in the first position P1 according to 5 , In the embodiment thus continues to find a deflection of the label tape 90 at the donation edge 26 instead, the donor edge deflection angle 29B but is smaller, and this is a donation of a label at the dispensing edge 26 prevented. In other words, the leading edge of the label 92 at the donation edge 26 so little deflected that the label 92 due to the connection to the carrier tape 91 not from the carrier tape 91 replaces. labels 92 For example, have a pressure-sensitive adhesive layer and releasably stick to a siliconized surface of the carrier tape. Other types of labels are possible.

4 shows an alternative embodiment 3 in which the second position P2 is achieved in that the deflection 42 relative to the donation edge 26 in the orientation according to 4 is moved upwards. The deflection part 42 is thus in the direction of the depression 24 move out. The deflection part 42 So it's in the first position P1 further inside in the depression 24 than in the second position P2 , The deflection part 42 can still contact the label tape 90 to have. Preferably, the deflection has 42 but no contact with the label tape 90 , and this will cause unnecessary friction in the area of the recess 24 and unnecessary contamination of the deflection by the side of the labels 92 emerging adhesive avoided. The label tape 90 is in the embodiment of the dispensing edge 26 not diverted. Here, the label tape 90 either contact the donor 26 have, or it may be by far at the dispensing edge 26 pass. This is the case, for example, when the tape guide element 22 right from the dispensing edge 26 is slightly increased. The position change device 46 is in the embodiment of the recess 24 opposite side of the label tape 90 arranged. The position change device 46 However, in the presentation of 4 below the depression 24 be arranged. To a course of the label tape 90 between the deflector 42 and the depression 24 to allow the position change device 46 For example, laterally from the area in which the label strip runs, with the deflection 42 be connected. The position change device is preferred 46 as shown on two opposite sides of the deflection 42 associated with this.

In the embodiment of 2 has the deflection part 42 in the first position P1 a contact with the label tape 90 in the depression 24 , The label tape 90 gets into the recess 24 pressed in, and it runs at least partially within the depression 24 ,

The depression 24 is thus an area in which the label tape through the deflection 42 can be pressed. The depression 24 may be completed here, but it may, for example, also be open at the bottom. The lateral walls of the depression 24 run in the embodiment perpendicular to the bottom of the recess 24 , However, they can also run obliquely or curved or not provided at all.

Preferably, the tape guide element 22 before and after the recess 24 in the first position P1 a contact with the label tape 90 , These are in 2 exemplary the places 71 and 72 located at which a contact of the tape guide element 22 with the label tape 90 occurs.

curvature

As in 2 is the donor device 20 trained to be in the first position P1 the first page 93 of the label tape 90 , which the deflection part 42 is assigned to the deflection 42 at least partially concave and at the dispensing edge 26 at least in sections, to curve convexly, since the label tape 90 preferably in the dispenser 20 is inserted in such a way that the labels 92 on the first page 93 are arranged and thus at the dispensing edge 26 can be dispensed well, leading to the concave curvature of the label strip 90 at the deflection part 42 to a curvature of the labels 92 , Subsequently, the label tape 90 at the donation edge 26 curved in the opposite direction convex. Due to the pre-curvature of the labels 92 at the deflection part 42 performs the convex curvature at the dispensing edge 26 to that the label 92 at the donation edge 26 lighter from the carrier tape 91 solves. This effect has proved to be very advantageous in experiments.

deflecting

Preferably, the tape guide element 22 a deflection edge 28 , which is adapted to a deflection of the label tape 90 without detachment of a possibly donated label 92 at the deflection edge 28 to enable. The provision of the deflection edge 28 limits the extension of the tape guide element 22 on the side of the deflection edge 28 , and thereby becomes the feeding of the items to be labeled 19 (see. 1 ) facilitated.

Preferably, the position of the deflection edge remains 28 relative to the donation edge 26 when changing the deflection 42 from the first position P1 in the second position P2 unchanged. This can, as in the embodiment, be achieved in that the deflection edge 28 firmly with the dispensing edge 26 connected is.

Change between positions P1 and P2

6 to 9 show an example of a transition from the first position P1 in the second position P2 ,

In 6 is the deflection 42 in the first position P1 , A first label 92A is at the deflection 42 diverted and at the dispensing edge 26 from the carrier tape 91 replaced. An object to be labeled 19 For example, a bottle or a tube is in the area of the dispensing edge 26 emotional.

In 7 is the label tape 90 moved on, and the detached label 92A is in contact with the object to be labeled 19 arrives. The representation is schematic, and it can, for example. A non-illustrated pressure roller may be provided to the label 92A to the object to be labeled 19 to press.

8th shows the dispenser 20 in the second state P2 , Between the state of 7 and 8th is the deflection part 42 from the first position P1 in the second position P2 been moved. Because the label tape 90 by the clamping of the brake device 15 (see. 1 ) is under tension, the course of the label tape 90 by the movement of the deflection 42 from the depression 24 straightened out, and in the embodiment, no deflection takes place at the dispensing edge 26 , In the embodiment, the movement of the deflection is 42 in the second position P2 during the movement of the label tape 90 he follows. The already detached label 92A can despite the change to the second position P2 continue on the object to be labeled 19 be donated. This is advantageous because it can be ensured at an early stage that the following label 92B not at the dispensing edge 26 donated. Alternatively, the change to the second position P2 take place only when the label 92A completely from the carrier tape 91 is replaced.

In 9 is the label 92A completely on the object to be labeled 19 attached, and the label below 92B is at the deflection edge 28 deflected and not from the carrier tape 91 replaced.

A change from the second position P2 in the first position P1 can in the same way already done when the deflected label 92B still in the area of the deflection part 42 is, and even if the label tape 90 is in motion.

10 shows in a three-dimensional representation of a Auskonstruiertes embodiment of the dispenser 20 ,

The dispenser 20 has a flange 70 for attachment to the labeller 11 (see. 1 ). These are on the flange 70 for example, fastening openings 71 one of which is visible. With the flange 70 are two arms 72 connected, and on the arms 72 is in the front area a plate 23 attached. The plate 23 indicates the depression 24 , the donation 26 and the deflection edge 28 on, so it serves as band guide in this area 22 ,

The plate 23 preferably has a thickness which is in the range of 5 mm to 35 mm, more preferably in the range of 7 mm to 20 mm. These areas make up the front area of the dispenser 20 on the one hand slim, and on the other hand, a sufficient stability is ensured.

The plate is preferred 23 provided at least in sections with a wear protection layer, in particular a hard-enamel layer. But there are also other wear protection layers possible. This will increase the life of the label tape 90 stressed surface significantly increased. Alternatively, aluminum-titanium can be used as a wear-resistant layer.

Above the plate 23 is a guide element 34 on the arms 72 attached, which is used to guide donated labels 92 serves. The poor 72 define a storage location 48 in cooperation with an axis 74 , At the depository 48 is a rotary arm 49 rotatably mounted, and the rotary arm 49 and the deflector attached thereto 42 are graphically provided with dots for clarity. The deflection part 42 is at the front of the arms 49 attached.

A label sensor 76 is provided and serves to the position of the label tape 90 to detect. This is, for example, for the control of the labeling 11 (see. 1 ) and for synchronization with the object to be labeled 19 (see. 1 ) advantageous.

The position change device 46 has actuators 50 in the form of pneumatic muscles. The actors 50 are on the one hand with the deflection 42 connected, in the embodiment via the rotating arms 49 , and on the other hand they are with the tape guide element 22 connected, in the embodiment over the arms 72 , The swivel arms 49 So also act as part of the position change device 46 , By a contraction of the actor 50 can those at the depository 48 mounted rotary arms 49 be tilted forward, and that with the rotary arm 49 connecting deflecting part 42 is thereby applied downward with a force, towards the first position P1 out.

Pneumatic muscles have the advantage that they can be switched very quickly and can generate large forces during contraction.

The actuators are preferred 50 each on the one hand via a first pivot 51 with the deflection part 42 and on the other hand, via a second pivot 52 with the tape guide element 22 connected. Such hinges 51 . 52 They are also referred to as pivot points, and they prevent bending forces on the actuator 50 arise when the rotary arms 49 perform a rotary motion.

11 shows the dispenser 20 from 10 in a front view in the direction of the arrow XI of 10 , From the front are below the deflection 28 and above that the guide element 34 visible. Between these parts is a slot 35 present by the label 92 (see. 2 ) can be donated.

The swivel arms 49 are in the embodiment of several parts on both sides of the arms 72 trained and connected to each other in the upper area.

12 shows the dispenser 20 of the page. The rotary arm 49 is rotatably mounted on the bearing, and by a contraction of the actuator 50 can the rotary arm 49 be tilted forward. This allows the deflection 42 into the depression 24 be moved into it and lead to a larger donor edge deflection angle.

13 shows the dispenser 20 from above. The label sensor 76 has a connection 77 in the embodiment via a cable with the label sensor 76 connected is.

A label web 95 is indicated by dashed lines, and the label tape 90 can be along the label web 95 in the tape guide direction 96 move. The label web 95 is continuously drawn, but it is partially hidden, for example. By the deflection 42 and the guide element 34 , The label web 95 is in the embodiment on the lower side by the arm 72 limited, the arm 72 So can as a lateral stop for the label tape 90 serve. Naturally, the tape guide element 22 also provide an additional part for the lateral guidance. In addition, a guide through the tape guide element takes place in the front area 22 especially through the plate 23 ,

The swivel arms 49 the position change device 46 are at junctions 81 . 82 at the side of the label tape 90 provided label web 95 with the deflection part 42 connected. This is advantageous because the threading of the label tape in the device of the dispenser 20 not or only slightly by the position change device 46 is hampered. In addition, thereby the dispenser 20 easy for wider label tapes 90 be modified because only the inner parts of the dispenser 20 must be replaced by wider parts.

14 shows a side view of the dispenser 20 corresponding 12 , The illustration is in the area of the outer part of the rotary arm 49 shown partially cut. At the inner area of the rotary arm 49 is a spring element 53 provided, which the position change device 46 acted upon in a predetermined direction with a force. The spring element 53 pushes down against the arm 72 and thus leads to a force that is the turning arm 49 counteracted with a force applied. As a result, the deflection part 42 in the direction of the first position P1 to the second position P2 acted upon with a force. The spring element 53 thus leads to the deflection 42 is acted upon by a spring force, that it out of the recess 24 is moved out. This direction is advantageous because then when the actuator 50 is defective, labeling of products is prevented. Such a defect can occur, for example, when the compressed air supply is interrupted. In case of a defect safe solutions are required in particular in the labeling of pharmaceutical products.

In the exemplary embodiment, the position change device comprises 46 the spring element 53 and the actor 50 , and by a contraction of the actor 50 can the deflection part 42 into the depression 24 and thus in the first position P1 be moved into it. The depository 48 is located below the depression 24 or more generally on the deflection part 42 opposite side of the depression 24 , and this has the advantage that the deflector 42 when turning into the recess 24 is moved in something forward. On the one hand, this causes the deflection angle at the dispensing edge 26 larger, and on the other hand is the deflector 42 in the second position P2 a little further from the donation 26 does not remove and therefore does not bother.

The controllable actor 50 is designed in the embodiment, a change from the second position to the first position P1 to enable. The change from the first position P1 to the second position P2 becomes with extending actor 50 by the spring element 53 causes or at least supports. The actor 50 from the embodiment is formed as a pneumatic muscle, and it can cause a large contraction force. In the relaxation of the pneumatic muscle, however, only small forces occur in the reverse direction, and therefore leads the spring element 53 to a safe operation.

Alternatively, an actuator may be provided, which is a change of the first position P1 to the second position P2 causes, and it can be used, for example, a spring for the opposite direction.

In another alternative, an actuator 50 be provided, which is both a change from the first position P1 to the second position P2 as well as a change from the second position P2 to the first position P1 allows. This is for example with an electric motor as an actuator 50 possible.

15 shows a section through the dispenser 20 longitudinal. The actor 50 is contracted, and the rotary arm 49 is with the deflector 42 tilted forward. The deflection part 42 is therefore in the first position P1 which is a donation of labels 92 at the donation edge 26 allows. The guide element 34 serves the purpose at the donation edge 26 To carry donated labels in a direction forward to allow labeling of an object to be labeled. Depending on the application, such a guide element 34 be used or it can be waived.

The guide element 34 is formed in the embodiment as a plate. It can also be designed as a sheet or comb.

16 shows the dispenser 20 in which the deflection part 42 in the second position P2 located. The label tape 90 will be at the donation edge 26 not or only slightly deflected, and therefore the labels remain 92 on the carrier tape and are transported with this.

17 shows a detail of 15 , the deflector 42 is thus in the first position P1 , It can be seen that the label tape 90 through the deflector 42 into the depression 24 is pressed and therefore at the dispensing edge 26 is diverted. This leads to a replacement of the labels 92 at the donation edge 26 ,

In the depression 24 is a screw 37 visible. This screw 37 serves to fasten the guide element 34 and is outside the label web 95 (see. 13 ) or side of the label tape 90 , The screw 37 therefore has no contact with the label tape 90 and does not hinder its transport.

18 shows a detail of 16 in which the deflection part 42 in the second position P2 relative to the donation edge 26 is. The deflection part 42 is raised or out of the recess 24 moved out, and the label tape 90 can undisturbed around the deflection 28 run around without one of the labels 92 donated.

19 shows enlarged the area of the dispensing edge 26 ,

The donation edge 26 is preferably formed as shown at least partially rounded. This causes the risk of tearing the label tape 90 at the donation edge 26 in the first position P1 of the deflection 42 relative to the donation edge 26 is greatly reduced. As in 1 is shown, pulls the drive roller on the label tape, and at the same time the label tape 90 through the brake device 15 clamped in an earlier area. This results between the braking device 15 and the drive roller 16 a force on the label tape 90 , which corresponds to a force that would produce a hanging on the label tape mass of 15 kg. In particular, in clocked operation, it can at the beginning of the movement profile to large forces on the dispensing edge 26 lead, and therefore the rounding off is very beneficial.

The deflection part 42 has a contact area 43 , which is adapted to, in the first position P1 with the label tape 90 to be in contact. The contact area 43 has a first area 44 and a second area 45 , where the second area 45 in the first position P1 closer to the donor edge 26 is considered the first area 44 , The first area 44 is less curved than the second area 45 , and this has the advantage that it is possible with the diverter 42 closer to the donor edge 26 get hold. At the same time is the extension of the way for the label tape 90 when changing the deflection 42 in the first position P1 due to the lower curvature in the first area 44 lower.

The depth of the depression 24 is marked with a T The depth is preferably at least 0.5 mm, more preferably at least 2 mm, and particularly preferably at least 3 mm. It is therefore possible to detach labels even with very shallow depths of depression 24 to enable. A technically specified maximum depth does not exist. From a certain depth, the depression is no longer exploited, but that does not bother.

Reduction of friction at the deflection edge

The surface of the deflection edge is preferred 28 at least partially microporous formed. As a result, the contact surface between the deflecting edge 28 and the carrier tape 91 reduces, and thus the friction in the area of the deflection 28 reduced.

In addition, compressed air can be supplied via the microporous structure, and this is distributed over the microporous structure and leads to an air cushion. The microporous structure can thus be provided both on the surface and in the inner region. For supplying the compressed air, for example, a - not shown - channel in the plate 23 be provided, via the compressed air in the region of the deflection 28 promoted and distributed there over the microporous structure, cf. 20 ,

20 shows an alternative to the embodiment of 19 , The dispenser 20 or the tape guide element 22 have channels 30 with channel openings 32 on. The canal openings 32 are in the area of the deflection edge 28 provided, and through the channels 30 is a supply of compressed air in the area between the deflecting edge 28 and the label tape 90 possible. This leads to an air cushion effect, and the friction between the label tape 90 and the deflection edge 28 is greatly reduced. This will cause a greater acceleration of the label tape 90 allows.

applications

21 shows a first application example of the dispenser 20 where the label 92 over the guide element 34 is guided and in the area of a pressure roller 97 in contact with an object to be labeled 19 arrives. The label 92 is then passed through the pressure roller 97 at the object 19 rolled. The label 92 preferably has a length which is at least the distance from the dispensing edge 26 to the pressure roller 97 equivalent.

22 shows another embodiment of the use of the dispenser 20 , A transport element 36 will be in the area of the donation edge 26 positioned, and the label 92 is donated and the transport element 36 fed. The transport element 36 is, for example, a suction stamp, the label 92 can suck. Subsequently, the transport element 36 moved to an object to be labeled, and that with the transport element 36 transported label 92 is mounted on the object. The at the donation edge 26 donated label 92 So it will be on the transport element 36 secured and can then be moved to another location and attached to a product.

23 shows another application example of the dispenser 20 which is used to donate labels 92 on objects 19 is provided with a cylindrical surface. The too tagging item 19 is via a transport device 98 in the area of the dispenser 20 turned, and over a belt 97 can the object 19 for the labeling process in rotation, passing over the rollers 99 to be led. Here are the belt 97 and the roles 99 a prism. For example, cans or bottles can be labeled with this device.

Naturally, various modifications and modifications are possible within the scope of the present invention.
