To understand surface product that has already been threaded into the conveyor unit and is funded by this. The second sheet-like area product is in the context of the invention, a surface product, which is introduced in particular to reserve in the output device. Thus, the second sheet-shaped surface product is not threaded into the conveyor unit or promoted by this, as long as the first web-shaped

Surface product is not used up yet. Advantageously, as soon as the first web-shaped area product has been used up, the second web-shaped area product is threaded into the conveying unit by means of the loading device and can be conveyed or dispensed therefrom. Advantageously, however, only the second web-shaped surface product in the first loading of the dispenser in the

Hereby, an alternative variant is shown, which causes the sensor arm to tilt into the first position, which indicates that web-shaped material is conveyed, this alternative variant being combinable with that of the provision of at least one sensor finger. In a further variant, it is provided that the sensor unit tilts without force on the first arm in a second position. As soon as For example, the tension in the web-shaped surface product significantly decreases, and thus no more force is exerted on the first arm, especially if the web-shaped surface product breaks off from a roll core, the sensor arm is taught that no or not enough surface product is available. The sensor arm thus tilts to the second position and causes the loading arm to thread surface product from the second roll.

The loading arm is preferably acted upon by a force in the direction of the drum. Preferably, the loading arm is acted upon by a spring force, which urges the loading arm in an active position. Further preferably, the loading arm is provided with at least one spring, preferably two springs, more preferably more than two springs which push or pull the loading arm in the direction of the active position.

This has the advantage that the einzahnelnde surface product must be unrolled from the role only a piece until it hangs in the sphere of influence of the loading arm. Since the loading arm is arranged on the cover part, no threading between loading arm and drum is necessary. It is sufficient to open the lid part. If the lid is closed, the loading arm can immediately, if no surface product be on the drum to be promoted or thread the newly inserted surface product in the conveyor. Furthermore, a method for threading a surface product to be dispensed into a delivery unit of a dispensing device is proposed, wherein the dispensing device comprises a housing part, a cover part and the delivery unit. The conveyor unit further comprises a drum, wherein the drum is associated with a loading device and the loading device comprises at least one loading arm. A roll with a sheet-like surface product is introduced into the dispenser, so that the sheet-like surface product is arranged between the loading arm and the drum. Detects, for example, the sensor device that no surface product is no longer present on the drum, this tilts in the second position, the control unit is relieved or moved by the loading arm and in particular withdrawn. Since the loading arm is now relieved, this is brought into the active position and pushes the web-shaped surface product against the drum. Preferably, the loading arm presses the sheet-like surface product against the drum so that the drum

Surface product promotes rotation of the drum.

In one embodiment, it is provided that a first roller with a first web-shaped surface product and a second roller with a second web-shaped surface product is introduced into the dispensing device, so that at least the second web-shaped surface product is arranged between the loading arm and the drum. Preferably, the second roll is introduced with the second surface product when the first sheet product is already threaded.

In a further embodiment it is provided that the loading device a

In particular, an embodiment provides that the sensor unit comprises at least one sensor finger, which corresponds to at least one groove in the drum, wherein a surface product on the drum lifts the sensor finger out of the groove. The sensor finger is preferably designed such that a newly threaded surface product can slide between the sensor finger and the drum. In particular, a pressure roller is arranged such that the surface product is threaded between the drum and the sensor finger. Furthermore, the force exerted by the sensor finger on the drum or on the groove of the drum, moreover advantageously on the surface product, which is located between the sensor finger and drum, is selected such that the surface product does not crack, not blocked and especially not in the Groove is pressed.

According to one embodiment, the pressure roller is positioned to the drum so that it has a distance of about 0.01 mm to about 1 mm. In a further

preferred embodiment, the pressure roller is designed such that it rests directly on the drum or can rest. A further embodiment provides that the pressure roller is designed to be movable.

An advantage of the detection by means of the sensor finger is that the sensor unit or the control unit can only then convert the loading arm in the active position, if actually no web-shaped surface product more on the

Drum is promoted. An advantage of the embodiment in which a force is exerted on the first arm by means of the tension of the web-shaped first surface product, is that the second web-shaped surface product is already promoted when surface product is still on the drum. This can be an advantage if you want to prevent a user from coming to the wrong conclusion Output device is empty.

According to one embodiment, the roller guide is designed such that, in particular as a function of a roller diameter, it guides the roller on a predetermined path through the interior of the dispensing device. In particular, the roller guide is designed so that, after consumption of the sheet-like surface product has taken place from the roll, the roll is transferred to a position in which another role can be inserted into the dispenser. The present invention further relates to an output device for dispensing a sheet-like surface product from a roll comprising at least a housing part and a roller guide. The roller guide comprises at least a first tread and a second opposing tread. Both treads form an inclined plane in the operating state of the output device.

In a further embodiment it is provided that the planes are arranged in particular such that the roller with decreasing roller blade D _R slips down the running surfaces.

The dispenser may, according to one embodiment, receive a roll of web-shaped sheet product which is coreless or core-finished. A coreless roll is in particular a winding of surface product, which is not on a core

or a winding or a coil or a sleeve is rolled up. According to one embodiment, such a coreless roll has insertion parts which are introduced in particular into a cavity of the roll. These inserts protrude, for example via cylindrical projections beyond the longitudinal extent of the role and can according to a further embodiment have rolling surfaces. These rolling surfaces are particularly suitable for unrolling on the running surfaces of the dispenser. In a further preferred embodiment it is provided that the roller has a roll core or sleeve. This roll core or sleeve can

be configured for example of plastic, cardboard or any other material or material mixture. In a further embodiment, it is provided that the roll core or sleeve has one or more separations. In particular, the roll core can be configured such that, as soon as the sheet material is removed from the roll core, it breaks up into several parts. This embodiment is called in technical jargon "split core". The design of the roll with a roll core can be designed according to one embodiment such that inserts are embedded in particular in the roll core or inserted, glued and / or clamped. According to a further preferred embodiment, it is provided that the insertion parts, which are inserted on both sides into the roll core or into the roll, differ in their design. It is preferably provided that a first insertion part has a smaller rolling diameter, provided, for example, by the cylindrical projections, as a second insertion part. Preferably, the dispensing device is designed such that the insert parts run on the treads in such a way, can roll or slip down, without causing the role in the output device tilted or unrolled.

Advantage of the embodiment with two different treads is that

On the production side can be specified in which orientation the role can be used in the output device. In particular, it is provided that the first running surface is designed such that it is not able to accommodate the second insert part. One

Inserting the roll with a wrong orientation is therefore not possible. The orientation is particularly important for the correct introduction of the sheet-like surface product between a drum and a loading arm, as explained above in connection with the further invention. Also, in a further embodiment of Output device, the orientation of the sheet-like surface product is important to avoid jamming or tilting of the surface product in the output.

In a further embodiment of the dispensing device it is provided that the running surfaces are inclined towards a rear wall or a limiting device.

In particular, the limiting device is assigned to the rear wall or arranged thereon. Preferably, it is provided that the inserted role the

Running surfaces as far down rolls or slips until an outer circumference of the roller rests against the rear wall and / or the limiting device. The advantage of this embodiment is that with progressive consumption of the web-shaped surface product, which causes the roll diameter is smaller, the role always at least up to a fixed roll diameter on the rear wall or

Limiting device is applied. The insert part or the roller runs down on the running surfaces.

In a further embodiment it is provided that the output device has at least one limiting device which is designed such that the in the

Roller guide arranged roller is prevented by the limiting device and depending on a roll diameter from slipping down on the treads. The limiting device is arranged according to an embodiment on the rear wall of the housing. Further advantageously, the limiting device is a part of the rear wall of the housing. Further advantageously, the limiting device is configured such that the roller can slide on it. More preferably, an embodiment is provided in which the limiting device is designed such that it guides the roller in dependence on the roll diameter and / or holds in position.

The running surfaces are in particular designed such that a rolling of the

Surface product of the role is easily possible. For this purpose, a plastic is preferably selected, which has a low frictional resistance matching the rolling surfaces of the insert parts. Furthermore, it is provided according to a preferred embodiment that the Clamping device is made of a material or coated with a material having a low frictional resistance with the surface product. The

Limiting device is geometrically designed such that the smallest possible surface presses against the surface product without too much buckling of the

Surface product is done by the limiting device. Preferably, at least the limiting device, at least one surface thereof facing the roll, and / or the treads comprise a material selected from a group comprising polyolefin, polyoxymethylene (POM), a polystyrene (PS) and / or a polyethylene (PE).

According to a further embodiment, it is provided that the roller guide comprises a tolerance compensation at least on one side. This has the advantage that at a

different length expansion of the individual roles, the respective role can be correctly inserted into the output device.

The rollers are provided with tolerances due to their production. In particular, tolerances in the range of the length of the roll are common. Furthermore, production-related often means that, when these insertion parts are provided, they are inserted differently far into the roll core or into the roll, so that they protrude differently far beyond the roll length. It is well known in the art to provide a rigid receptacle for the rollers. This has been found to be disadvantageous since the roller, should it have a longitudinal extent below a small dimensioned

Have tolerance range, slips out of the roller guide and in particular of the treads. This leads to tilting of the roll within the dispenser and the roll can not be used further, or the output device can not spend another surface product.

A variant provides that the tolerance range comprises at least the second tread, which can be issued in a lateral orientation. In the lateral direction is especially in

Longitudinal direction of the roll. That is, the tolerance range is according to an embodiment designed so that this, the role should not be the maximum allowable

Have longitudinal extent, in particular less than the maximum intended longitudinal extent, the at least second tread in the direction of the role, that is in the lateral direction of the dispensing device is issued, so that the role still on or the rolling surface of the insertion can still roll on the treads. An exhibition in the lateral direction may also include tilting or tilting of the tread, in particular the second tread, in the direction of the roller or housing center.

In a preferred embodiment, it is provided that the tolerance range is resiliently mounted. In particular, at least one leaf spring is provided, which causes the exhibiting of the tolerance compensation or the second tread. In further

Embodiments are also other spring mechanisms, in particular at least one torsion spring or at least one helical pressure fields, provided. According to a further embodiment it is provided that the spring comprises at least one material selected from a group comprising a metal or a plastic, in particular polyoxymethylene (POM).

In a further embodiment it is provided that the tolerance compensation is articulated on a lateral wall, for example, a side wall and / or insert wall. The tolerance compensation, which has at least one tread, can be configured as a flap or rocker similar. This allows easy handling especially when inserting the roll. If the tolerance compensation, for example, resiliently mounted, this is preferably moved when inserting the roller in its center of the housing facing position and then placed the role on the tread of the tolerance compensation and subsequently placed on the opposite tread. In consequence, for example, the laying of the opposite insert in or on the opposite

Fig. 1 shows an output device 10 with a housing part 14 and a hinged to the housing part cover part 12. The cover part 1 2 is hinged to the housing part 14 via a hinge 1 3 on the housing part. As can be seen from FIG. 1, the cover part 12 is pivoted upwards in order to open the dispensing device 10. For safety, to prevent unauthorized access to the dispenser, a locking means 210 is provided. It can also be seen from FIG. 1 that the dispensing device outputs a web-shaped surface product 26. 2 shows the dispensing device 10 with the lid part 1 2 open. It can be seen that the lid part 1 2 is held in an open position by means of an opening arm 110. The opened lid 12 releases the view into the housing 14, in which a roller 28 with a surface product 26 is arranged. The surface product 26 extends into one

Feed unit 30, which conveys and outputs the surface product 26 of the roller. FIG. 2 further shows that in addition to the side walls 18 and 20 of the housing 14, insert walls 40 and 42 are also provided. These insert walls 40 and 42 are separate components, on which in particular functional parts are integrated or arranged. An embodiment in which the insert walls 40 and 42 receive all functional parts of the housing sides, allows greater freedom of design of the side walls 18 and 20 of the housing 14th

FIG. 3 shows the dispenser 10 from FIG. 2, wherein a majority of the web-shaped area product 26 has been unwound from the roll 28. As can be seen in this and the following Fig. 4, slides a longitudinal axis of the roller 28 in response to their

Diameter along a predetermined path through the housing part 14th

Fig. 4 shows, inter alia, the rear wall 16, in the key 207 for the

Locking means 210 are inserted so that they are easily heraussennbar by a user. FIG. 5 shows the dispensing device 10 without an inserted roll with surface product, wherein a conveyor unit 30 is folded out into a maintenance position. The conveyor unit 30 comprises a drum 32 for conveying surface product, as well as a mechanical sensor unit 506 with a first arm 507 and a second arm 508. The second arm 508 of the sensor unit 506 has in the Fig. 5 shown here hidden sensor fingers, which in groove 51 3 of the drum 32 engage.

Furthermore, it can be seen from Fig. 5, that the conveyor unit 30 at the

Output device 10 is articulated. In the embodiment shown here is the

Linkage made on the insert walls 40 and 42. That is, it is between the insert walls 40 and 42 and the conveyor unit 30, a concealed hinge provided here. The conveyor unit 30 also has locking means 402, which cooperate with locking means 408 on. The locking means are releasable by actuation of the actuating lever 406 of the locking means 408.

6 shows a cross section through the dispensing device 10, wherein it can clearly be seen that a first roller 28.1 with a first web-shaped surface product 26.1 and a second roller 28.2 with a second web-shaped surface product 26.2 are inserted into the dispensing device 10. Due to its smaller diameter, the first roller 28.1 has already slid in a residual roll receiving position. The second roller 28.2 is arranged due to the later explained roller guide in connection with its diameter still above the first roller 28.1. The roller rests with its outer circumference on at least one limiting device 614. The web-shaped area product 26.1 of the roller 28.1 is guided above an axis 830 and over the first arm of the sensor unit 506. The surface product 26.1 extends between the pressure roller 33 and drum 32. By means of the drum 32 is the

Surface product 26.1 promoted and output from the output device 10. A cutting device not shown here, which is arranged in the drum 32, portions the web-shaped surface product 26.1 into individual sections. By the mentioned leadership of the role as a function of its diameter is at a certain roll diameter of the roller 28.1 sufficient space in the

Dispensing device 10 free to place a second roller 28.2 in the dispenser 10. A loading device, which includes the mechanical sensor unit 506, a control unit, which is not shown here, and a loading arm 520, allows the automatic reloading of the surface product 26.2 of the second roller 28.2, as soon as the sensor unit 506 detects that no surface product 26.1 more on the Drum 32 is present. In Fig. 6 is further seen that stripping ribs 50 strip the surface product 26.1 of the drum 32.

Fig. 7 shows the longitudinal section of Fig. 6, wherein the first roller 28.1 is removed with the first sheet-shaped surface product 26.1, for example, because the first roller 28.1 has been consumed. Since surface product 26.1 is no longer guided on the drum 32, the sensor finger 512 can engage in the groove 51 3 on the drum 32, wherein the mechanical sensor unit 506 tilts with the side arm 508 in the direction of the drum 32. By this tilting movement of the sensor unit 506, the loading arm 520 is caused by means of a spring mechanism, not shown here, to issue in the direction of the drum 32. In this case, the web-shaped area product 26.2 is pressed by the loading arm 520 between the drum 32 and the pressure roller 33. When the drum is actuated, the surface product 26.2 is pulled between the pressure roller 33 and the drum 32 and the drum 32 is conveyed. FIG. 8 shows, inter alia, an empty roll core 28.3 which lies in a roll core receptacle 636. Inserted parts 640 and 642, which each have a different geometric configuration, are embedded in the roll core. In particular, the first one

Insert part 640 a first rolling surface 61 7 and the second insertion part 642 and a second rolling surface 618 on. FIG. 8 also shows an actuating means 702 connected to two racks 704. The racks are part of a not recognizable in detail here

Drive train 71 3, which cause a drive of the drum 32. Furthermore, it can be seen from Fig. 8 that the actuating means 702 is reset by means of return springs 706 after actuation.

9 shows the drive unit 34 of the dispensing device 10. In particular, it can be seen that a part of the recharging mechanism, in particular the mechanical sensor unit 506, is articulated to the drive unit 34 by means of a control unit 515. It can also be seen that the actuating means 406 together with the latching means 402 on the drive unit 34

is arranged.

The drive unit 34 comprises an actuating means 702 which is rigidly connected to two racks 704. A return spring 706 causes a reset of the actuating means 702 after actuation, that is, after pressing the actuating means 702 by a user in a starting position shown here. If the user presses the actuating means 702, this is displaced, wherein the racks with a pinion 708

interact. The pinions 708 are via a shaft 710 for synchronization

connected with each other. The pinion 708, which is part of the drive train 71 3, is connected via a freewheel 712 with a second gear 714. The freewheel 712 ensures that the second gear 714 is entrained by the pinion 708 upon actuation of the actuating means. When the user leaves the actuating means 702, the return springs 706 return the actuating means 702, with the pinion 708 also moving in the opposite direction. The freewheel 71 2 between the pinion 708 and the second gear 714 causes that during this return movement, the second gear 714 does not move.

Moments that are transmitted to the second gear 714 are in the embodiment shown via a third gear 71 and a fourth gear 69 6 71 on one of

Drum 32 associated wheel 720 transmitted. The drum 32 associated with the wheel 720th is connected by means of a drum coupling 732 with the drum 32, not shown here. In a further embodiment it is provided that additionally or alternatively, the drum clutch 732 has a freewheel, which allows a movement or rotation of the drum 32 in one direction only.

A joint 412 makes it possible to pivot out of the delivery unit 30, not shown completely here, the part of which is the drive unit 34, out of the delivery device 10. FIG. 10 shows a further view of the drive unit 34 from FIG. 9, in which it can be seen that a ratchet wheel 728 and a pawl 730 engaging therein are provided on one side on the drive unit 34. Furthermore, it can be seen from FIG. 10 that on the

Ratchet wheel 728 or on the drive train 71 3, a bending field 724, which is guided around a deflection means 726, is arranged. If the drum 32 or the drive train 71 3 is actuated, the ratchet wheel 728 also rotates, wherein the spring 724 is further deflected. It can be clearly seen that, as soon as the bending spring 724 is deflected so far that a defined rotation of the ratchet wheel 728 or the drum 32 has occurred, the bending field 724 strives into a low-energy state, this effort the remaining rotation up to a basic position shown here performs. This is made possible by the freewheel 712 in the drive train 71 3, without the actuating means 702 being moved thereby. In the case in which by actuation of the actuating means 702, the above-mentioned defined revolution in which the

Bending field 724 can perform the remaining rotation, has not yet completed, prevents the ratchet 728 with the pawl 730 a turning back of the drum 32. A second actuation of the actuating means 702 then drives the drum 32 and the drive train 71 3 exactly from the position or from the

Rotation angle at which the drive train 71 3 and the drum 32 is held by the ratchet wheel 728. Fig. 1 1 shows a sectional view through the conveyor unit 30, wherein in addition to the

Drive train 71 3 with the rack 704 and the freewheel 71 2 also a cam track 312 can be seen. Clearly visible is a first cam 308 one not here

illustrated knife carrier which engages in the cam track 31 2.

FIGS. 12, 13 and 14 show the conveying unit 30 of the dispensing device 10 in a schematic view for explaining the cutting device 304. The cutting device 304 has a knife carrier 306 and a knife 307 that is movably mounted in the drum 32 , The first cam 308 and a second cam 310 are on the knife carrier

10 306 arranged. The first cam 308 engages in the cam track 31 2, which is associated with one end face of the drum 32. If the drum 32 rotates about its longitudinal axis, which is perpendicular to the image plane in the figures, the first cam 308 is guided in the cam track 312, so that the knife 307 arranged on the knife carrier 306 passes through a recess 324 in the casing 320 of the drum 32 passes. For radial guidance of the knife carrier

15 306 or of the blade 307, a first cam guide 314 is provided, through which the first cam 308 engages. The first cam guide 314 is disposed on the end face of the drum 32. As can be seen in Figs. 1 3 and 14, the blade carrier 306 is moved in accordance with the guidance of the cam track 31 2 in connection with the cam guide 314 during the rotation of the drum 32. A second cam guide 316, the

20 is arranged, in particular on the end face of the drum 32, performs the second cam 310. By not parallel to the first cam guide 314 second

Cam guide 316 is achieved in that the knife carrier 306 is tilted during a circumferential movement of the drum 32 about a longitudinal axis 322 of the first cam 308, which extends perpendicular to the image plane. Preferably, as also shown here,

25, the second cam guide 31 6 extends in a curved path. The train is like that

designed that the knife 307, in particular a cutting edge 305 of the blade 307, during the circumferential movement of the drum 32 first performs a movement parallel to the first cam guide 314. If the knife 307 partially exhibited and in particular has already made contact with the sheet-like surface product, becomes this first

30 movement component 326 a second movement component 328 of the Cutting edge 305 of the blade 307 executed. The two components of movement 326 and 328 are indicated by way of example and in the form of a sketch in FIG. 1 3. This additional direction of movement, which is achieved by the special cam guide of the second cam guide 316, leads to a cutting movement, wherein the surface product 26.1 is not simply torn or pushed through as known from the prior art cutting devices, but a clean cut is made.

FIGS. 15 to 18 show further sectional views of the dispensing device 10, in which some individual parts are clearly visible.

FIGS. 19 and 20 show a partial view of the dispensing device 10 with the lid part 1 2 open. It can be clearly seen, arranged in the second insert wall 42, a

Tolerance compensation 620 with a second running surface 61 2. The tolerance compensation 620 is articulated to the second insert wall 42 and subjected to a force by means of a spring 622. The spring 622 deflects the tolerance compensation 620 in a flared position in the direction of the housing interior. Fig. 19 shows the tolerance compensation 620 in the deployed position and Fig. 20 shows the tolerance compensation 620 in the force-loaded position. A roller, not shown here, is inserted into the dispensing device 10 such that the first rolling surface 61 7 of the first insert part 640, which is not shown here, is inserted into the first running surface, which is not visible here. The second rolling surface 61 8 is set to the second running surface 612, which is arranged on the tolerance compensation 620, such that the tolerance compensation 620 is tilted according to the longitudinal extent of the roller in the direction of the housing interior so far that a safe running of the rolling surfaces 61 7 and 618 on the treads 610 and 61 2 is made possible. When the roller is inserted, the insertion parts 640, 642 and / or an end face of the roller 28 press on the tolerance compensation 620, so that it is held in the optimum position.

FIGS. 19 and 20 further show a limiting device 614, which is the

Assigned rear wall 16, or arranged at this. One in the

Dispensing device used in particular full role lays down with its outer circumference against this limiting device 614. In order to allow easy rolling of sheet product from the roll, this limiting device 614 is made of a smooth as possible material in particular plastic, preferably polyoxymethylene or metal configured. Furthermore, FIGS. 19 and 20 show the sensor unit 506 with the two arms 507 and 508. The sensor unit 506 acts via a control unit 515 which amplifies the force and travel of the sensor unit 506 for actuating the loading arm, which is not shown here.

FIGS. 21 to 24 each show schematic sectional views of the dispenser 10, in which the travel of the roller 28 through the dispenser 10 is illustrated as a function of its diameter D _R. FIG. 21 shows a newly inserted roller 28 in which the insert 40 with the rolling surface 61 7 can be seen schematically. The roller 28 has a diameter D _R and lies with the rolling surface 61 7 in or on the

Tread 610 on. The running surface 610 is designed as a channel which limits the movement of the insertion part 640 or the roller 28. If the roller 28 is inserted into the running surface 610, it moves a bit in the direction of the rear wall 16 of the

Receiving device 10, until it rests with its outer periphery on the boundary part 614. Characterized in that the roller 28 with consumption of the surface product in diameter D _{R is} smaller, the insertion part 640 of the roller 28 rolls over the rolling surface 61 7 on the first tread 610, which forms an inclined plane down. This is illustrated in FIG. 22. It can also be seen that the first running surface 610 is configured in such a way that, when the roll diameter D _{R is} below a certain value, the roll 28 to

Rest roll pickup 630 drops. This condition can be seen in FIG. If the roller 28 has fallen into the position in which it is held by the remaining roll receptacle 630, the web-shaped area product, which is not shown here in the figure, lies over the first arm of the sensor unit 506, likewise not shown here. The residual roll receptacle 630 is configured such that it has a distance from the rear wall 16 which corresponds approximately to the diameter of the roll core 29, and preferably slightly larger than the diameter of the roll core 29 is. Once the surface product has been consumed on the roll 28, the roll core 29 between the remaining roll receptacle 630 and the rear wall 16 passes through into the roll core receptacle 636. This is shown in FIG. FIGS. 25 to 28 illustrate the loading device of the dispensing device 10. FIGS. 25 and 26 show a first roller 28.1, which is located in a rest roller receptacle, not shown here, and a second roller 28.2, which rests on the running surfaces not shown here. Fig. 25 is a partial perspective sectional view, and Fig. 26 is a sectional view. In FIGS. 25 and 26, it can be seen that the sensor finger 51 2 of FIG

sheet-shaped surface product 26.1, which is guided over the roller, is lifted out of the groove 51 3 of the drum 32. The sensor unit 506 then acts on the

Control unit 515 on the loading arm 520. Sensor unit 506 and control unit 515 are mounted in the same pivot bearing, with a tilting or pivoting of the sensor unit 506, the control unit 515 is moved. The control unit 515 acts on the loading arm 520 and pivots it against a force exerted by a spring 522, in the direction of the cover part 12. Preferably, a plurality of springs between cover part 12 and loading arm 520 are arranged so that the loading arm 520 moves smoothly.

FIGS. 27 and 28 show the condition of the loading device when missing

Surface product on the drum 32. The surface product 26.2 is between the am

Cover part 12 arranged loading arm 520 and the drum 32 loosely inserted. Since there is no surface product on the drum 32, the sensor finger 512 of the

Sensor device 506 in the groove 51 3 of the drum 32 a. As a result of this engagement, the second arm 508 of the sensor device 506 tilts in the direction of the drum 32

Tilting movement is also the control unit 51 5 taken, which is in particular by means of a torsion spring frictionally connected to the sensor unit 506. The movement releases the loading arm 520, which in turn pivots in the direction of the drum 32 by the spring 522, which is arranged on the cover part 1 2. In this pivoting movement is the Surface product 26.2 of the roller 28.2 pressed against the drum 32, in particular between the drum 32 and the pressure roller 33. If the drum 32 is driven or rotated about its longitudinal axis, the surface product 26.2 between the pressure roller 33 and drum 32 is pulled. In the following, since the surface product 26.2 is now conveyed via the drum 32, the sensor finger 512 is lifted out of the groove 51 3 again, so that the loading arm 520 is pushed back into its inactive position. This avoids that the loading arm 520 presses during normal operation on the drum 32 and the surface product 26.2 and unnecessarily increases the friction and thus the force required to operate the dispenser 10.

FIGS. 29 to 33 show an embodiment of the dispenser 10 with different guidance of the surface product 26. The roller 28 with the surface product 26 is inserted into the dispenser 10 with a unwinding direction in this embodiment. In particular, the embodiments of the dispenser 10 of FIGS. 2 to 4 correspond to the embodiments of FIGS. 29 to 31 and FIGS

Embodiments of FIGS. 6 and 7, the embodiments of FIGS. 32 and 33 respectively with opposite rolling direction of the roller 28 and the rollers 28.1 and 28.2.
