Description

The present invention relates to a dispenser for roll-wound flat products comprising a lid member having a front wall and a housing member, the housing member comprising a back wall and first and second side walls forming an interior, and a use of the dispenser of the invention.

Dispensing devices of the type mentioned above for dispensing sheet-like products wound into rolls are widely known from the prior art. In addition to such dispensers, which store only a single roll, those are also known which store two rolls, so that when a first roll is completely used, a second roll is tracked and made available to the user of a dispenser. Such dispensers facilitate their maintenance by operators who insert reels into the dispensers, thereby reducing costs.

Such devices, which output to roll wound flat products, be it those which have a perforation or the like to form individual surface portions, be it those which form an endless roll without any perforation or the like, often have the disadvantage that the mechanism for Tracking the second replacement role in consumption of the sheet product of a first role is complicated. Often, for this purpose, the user of a corresponding dispensing device is proposed to have two parallel juxtaposed rollers of flat products. But here, too, the user must manually move, for example, a housing part along a longitudinal axis of the rollers to then have access to the replacement role.

EP 0 824 494 B1 discloses a dispenser for flexible roll wound sheet material, preferably toilet paper, having a wedge guide system located on the inner wall of the dispenser, which provides for vertical slipping of a two roll, which is in a reserve position, while a first roll is engaged. Each sheet roll includes flexible sheet material, a hollow center core, and first and second end caps attached to end-to-end ends of the center core.

EP 0 824 494 B1 also discloses an output device having a cover part, a housing part and a hinge axis of a swing arm. FR 1 407 112 A discloses an output device for flexible roll-wound sheet material having two oscillating arms coupled to each other. The above and thus the cover part of the output device closer associated swing arm with a spreading portion has the function to hold another role in a holding or reserve position. The lower swing arm, which is more closely associated with the removal opening for flat products wound onto rolls, has a 1-axis positioning function.

It is therefore an object of the present invention to provide an output device which is small in size and facilitates the dispensing of sheet-wound products.

To solve this problem, an output device of the type mentioned is proposed, wherein one of the two side walls associated with a swing arm is articulated, wherein a hinge axis of the swing arm between the front wall and rear wall and is aligned transversely to a longitudinal extension of the swing arm, wherein the swing arm below the Hinge member arranged guide member and arranged above the hinge axis holding part, whose interior facing surfaces an obtuse angle α in a range of about 130 ° to about 176 °, preferably in a range of about 150 ° to about 175 °, more preferably in one Range from about 160 ° to about 173 °, form. The guide member has at its lower end portion arranged in the direction of the hinge axis broadening section.

As far as in the present invention, the term "about" or "substantially" is used in terms of values or ranges of values, this is to be understood as meaning that the person skilled in the art will regard as expert in the given context. In particular, deviations of the stated values of +/- 10%, preferably +/- 5%, from the term "about" or "essentially" are included.

As far as in the context of the present invention, the speech is that one or the other means associated with one of the two side walls, so this is not to be understood that the respective means are arranged directly on the side wall. Rather, it may also be in the sense of the present invention z. B. be that the side walls in turn assigned insert parts which are aligned more or less parallel to the side walls, and therefore can be addressed as lateral inner walls. Means arranged on these insert parts are likewise to be regarded as being associated with the side walls in the sense of the present invention. Of course, the respective means can also be assigned directly to the side walls.

As far as in the context of the present invention, the speech is that the hinge axis of the swing arm between front wall and rear wall is aligned, this is to be understood such an orientation in which the hinge axis is formed approximately at right angles with respect to the front wall and rear wall.

As far as in the context of the present invention, it is mentioned that the hinge axis is aligned transversely to a longitudinal extension of the swing arm, as the latter is an education to understand in which the swing arm extends longitudinally between a bottom part and a top floor of the dispensing device according to the invention. The dispensing device according to the invention may have a topsoil which is part of the cover part or of the housing part, and is preferably part of the cover part. The bottom part can also be formed by the cover part or by the housing part in the sense of the present invention, for example, a collecting means may have, with which empty rollers or insert parts, also called "plugs", at both ends of an inner core, as an inner wrap or sleeve, the roll of sheet-like products are introduced, are collected.

According to the invention, a device for exchanging a first used-up roll of planar products by replacing a second roll of flat products is made available, without the user of the output device having to take measures for this independently beyond the usual tearing off of flat products. If, for example, via guideways, in particular those which are prepared for said plugs, and those of the first and second side wall, facing the interior of the dispensing device according to the invention, placed a first roll by an operator, it runs along surfaces of the holding part and the guide part within the guideway in a consumption position. In this case, the swing arm of a receiving position moves about its axis of rotation such that the holding part projects into the interior of the dispensing device according to the invention and provides a support for a spare roll to be inserted, which is held in this holding position spaced from the first consumption roll.

In a particularly preferred embodiment, the holding part comprises an angled holding section at its upper end region. As a result, it is advantageously possible for a sufficiently secure position of the replacement roller in the holding position in the dispensing device according to the invention to be made available with only a small overall depth with regard to the joint movement of the oscillating arm.

More preferably, a surface of the holding member and a surface of the holding portion forms an angle β in a range of about 25 ° to about 75 °, more preferably in a range of about 35 ° to about 50 °. With such an angular range, a small overall depth with respect to the articulated swing arm is achieved based on the overall size of the dispensing device according to the invention.

In another embodiment, the holding portion has first and second surfaces facing the interior of the dispenser housing. The first surface of the holding portion preferably connects to the surface of the holding member such that the first surface of the holding portion with respect to the surface of the holding member into the interior of the housing of the dispenser by an angle of about 5 ° to about 80 °, preferably about 10 ° angled to about 45 °. The second surface of the holding portion preferably connects to the first surface of the holding portion such that the second surface of the holding portion is angled away from the interior of the dispenser housing by an angle of about 30 ° to about 120 ° with respect to the first surface of the holding portion about 60 ° to about 95 °, angled.

In a preferred embodiment, the swing arm has an angle γ between a longitudinal side edge of the guide part and a lower edge of a subsequent section. Preferably, the angle γ has a value of about 85 ° to about 140 °, more preferably a value of about 105 ° to about 125 °. The section adjoining the guide part and encompassed by the latter is preferably elongated and preferably lies in a plane defined by a surface of the guide part or is formed in the direction of the articulation axis. Preferably, the section a thickness corresponding to the guide part. The section may, for example, also have the same width as the guide part below the holding part, and thus also be addressed as an angled extension of the guide part.

According to the invention, the section arranged at the lower end region of the guide part is designed as a broadening section arranged in the direction of the joint axis. In the direction of the articulation axis in the context of the present invention means an orientation in a plane in which the articulation axis, which runs transversely to a longitudinal extent of the oscillating arm through it, and which extends between a bottom part and a top floor of the device. A joint housing, which is provided for fastening the swing arm in the housing part, which at least partially comprises the hinge axis, is preferably designed to extend in the direction of a widening section. By the widening portion has in a lateral view, as seen from the direction of the opposite side wall, the swing arm in an approximately racket-like, especially hockey or golf club-like appearance.

Preferably, the widening portion has a greater width than the remaining part of the swing arm. Preferably, the broadening portion has a width at least about 10%, more preferably about 50% greater than the rest of the swing arm. In the context of the oscillating arm is preferably to be understood as the width of the amount of a vector which is substantially perpendicular to the translational direction of movement of the roller when consuming flat products within the device and perpendicular to the normal of the side walls of the housing part.

In a particularly preferred embodiment, the angle γ between a longitudinal side edge of the guide member and a lower edge of the broadening portion is in a range of about 85 ° to about 140 °, more preferably in a range of about 105 ° to about 125 °. In such an embodiment of the swing arm is due to the widening section with a reduction of the roll diameter by handling the sheet product from the roll by the user nonetheless via a the largest possible contact surface of leading role to give a secure hold until the last flat product is unwound from the roll.

In a further preferred embodiment, the widening portion has an upper edge which is s-shaped from the guide part towards its end. Through this s-shaped upper edge, a considerable spread of the widening section is achieved. The upper edge is preferably rounded in the direction of the roll used in the dispensing device according to the invention, as is preferably the case with all the edges of the swinging arm which face the roll (s). Due to this widening due to the S-shaped course of the upper edge of the widening portion of the guide part, a secure guidance of the roll, from which a flat product is unwound by a user, is provided even with a reduced diameter thereof.

Further advantageously, the lower edge of the widening portion is substantially rectilinear. This ensures, inter alia, that a removal opening of the dispensing device according to the invention is not reduced in size via the fee.

The angle γ of the oscillating arm causes a roll of planar products provided with inserts ("plugs") in the core to move from the upper holding position into the lower dispensing position of the dispensing device, initially substantially downwards along the oscillating arm. Below the angulation of the swing arm described by angle γ, movement of the roll along the swing arm toward the front wall of the dispenser occurs at least partially, to a point where the roll of sheet products contacts an inside surface of the front wall of the dispenser. By this contact of the roll of sheet products with the front wall of the dispenser, as a first advantageous effect, the roll of sheet products is securely held in position. With decreasing diameter of the roll of sheet products by use, the roll of sheet products is guided further toward the front wall of the dispenser along the swing arm of the dispenser and initially remains in contact with the front wall of the dispenser. With further decreasing diameter of the role of flat products due to use, the role of flat products moves to the end of the swing arm. As soon as the roll, as the diameter decreases further, may lose contact with the front wall of the dispenser, this destabilizes the roll of sheet products even prior to complete consumption of the sheet product. This could lead to the fact that the role of flat products collapses before the complete consumption of the sheet product by a divergence of the plugs or staggered and the removal of the sheet product is hindered. In order to ensure a sufficient stability of the role in the dispensing position at almost complete consumption of the role of flat products, ie with a small diameter of the roll flat products, which in particular is no longer in contact with the front wall of the dispenser, is the End region below the bend described with angle γ preferably provided as a broadening section and more preferably as a hockey or golf club-shaped broadening section. As a second advantageous effect, the lack of stabilization of the roll at a greatly reduced diameter, after almost complete use of the roll, which may be particularly caused by the loss of contact with the front wall of the dispenser, is counterbalanced by the widened contact surface of the "plug" with the widening portion ,

In a further preferred embodiment, the hinge axis, based on a total length I of the swing arm, about 30% to about 50%, preferably about 38% to about 48% of the total length I below an upper end of the swing arm arranged. The hinge axis is advantageously displaced eccentrically in the direction of the end region of the guide member. By such an arrangement it is ensured that the hinge mechanism when using a consumption role and subsequent use of a spare roll, which is held in the holding position, works safely. It is ultimately achieved that the swing arm can be made extremely compact, and that no further aids except a bearing of the swing arm via the arranged on this joint housing on an example pin-like, preferably in cross-section part-circular projection, arranged in an insert part, which is associated with the side wall, or untermittelbar in the side wall, is necessary, wherein a connection between the joint housing and storage means can be done for example by a latching of the joint housing on the storage means.

In a preferred embodiment, the swing arm is arranged in a first guide track, assigned to one of the two side walls. The guideway can be arranged on an insert part, parallel to the side walls in the interior of the housing part. The arrangement within the guideway ensures the operation of the swing arm when using a consumption role and subsequently a replacement role. The guideway is advantageously designed such that in this a roll of flat products, provided with a core arranged in the insert part (plug), is performed.

More preferably, the first guide track in an upper end region at an angle which corresponds approximately to the angle γ of the guide member. More preferably, a wall of the first guide track is formed such that an insert part ("plug") of the roller can be guided along the wall, so that it provides the wall with a sliding or rolling surface. The guide track preferably comprises a web formed on a wall part or an inner surface of a side wall. This web has the wall, which faces the swing arm. The web is preferably formed by the swing arm and its outer edges are adapted at least in the region of the guide part. The (inner) wall of the web is preferably formed at a distance from a circumferential side edge of the swing arm. In the upper region of the holding part with the holding section, the web has an angled portion to form a widening for simplified reception of the roll-shaped product.

In a preferred embodiment, the first guide track is substantially adapted to an outer contour of the swing arm. Especially in the field of Widening portion of the swing arm is adapted to the first track of the outer contour thereof.

The first guide track advantageously has a projection in the direction of the interior of the housing part with respect to a surface of the guide part or of the holding part of the swing arm, so that reliable guidance of the consumable roller is ensured.

The first guide track preferably has a projection in a region with respect to a surface of the guide part of the swinging arm.

In connection with the first guide track, "supernatant" is to be understood as meaning that the first guide track has a greater extent into the interior of the housing at least in one area than the swing arm, regardless of the position in which it is located.

In a particularly preferred embodiment, in a region assigned to the holding section, the first guide track has a first recess. As a result, when the consumable roll is replaced with the spare roll, the swinging arm can move sufficiently far with its holding portion towards the one side wall of the housing part, so that the supply roll is transferred from its holding position and along the surfaces, the holding part, and the guide part, into the Output position is transferred.

In a further preferred embodiment, in a region facing the widening section, the first guide track has a second recess. This serves to receive the widening portion in a swinging back of the same when using a consumption role before introducing a supply roll. As a result, the dispensing device according to the invention can ultimately be made small in size with regard to its width.

In a particularly preferred embodiment, the first guide track has a width b ₁ which is greater than a width b _{2 of} a second guide track which is opposite this and which is assigned to the further side wall. If, in particular, the plugs already mentioned above are used to hold the flat products wound up into rolls, a wrong insertion of the roll can be reliably avoided with a corresponding configuration of the plugs, since only that insert part for the roll (plug) can be inserted into the respective guide track, which also accommodates a corresponding width thereof, and is not wider than a guide means arranged on the insertion part (plugs), which is arranged in the form of a cylinder in the direction of the guide track projecting on the replacement part.

In a further preferred embodiment, arranged on an inner side of the front wall of the lid part are at least two positioning means with end faces which are associated with end areas of the first and second guide tracks. These at least two positioning means with end surfaces support the unrolling of the consumable roll in the dispensing position in the region of the broadening section of the guide part, so that the unwinding takes place as far as possible without canting of the flat product wound into rolls.

In a further preferred embodiment, the side wall, which faces the side wall with the swing arm, a pressure arm for adjusting a holding pressure for used in the device rolling flat products is arranged. By the pressure arm and a corresponding adjusting device, it is easily possible for an operator of the execution device according to the invention, even with different roller widths, which already exist due to production conditions, set a holding pressure such that nevertheless a reliable guidance of the rollers used in the dispensing device according to the invention is ensured, as well as a safe removal of the respective surface portions of the sheet product from the dispenser.

In a particularly preferred embodiment, a collecting means is arranged below the removal opening provided in the device. The collecting agent is used in particular the absorption of spent winding or roll cores for the rolls and / or the mentioned insertion parts (plugs) after complete unrolling of the sheet product from a roll. The moment the reel is fully unwound, the plugs become free to move and fall into the catcher as well as inner reels, which may also be split. In such an embodiment, each insert part (plug) is inserted in a partial role. Full unwinding releases the pressure on the widening area of the guide means, the swinging arm swings back to a picking position, and the spare roll can be transferred to the use position. It can also be provided that, instead of or in addition to the mentioned insertion parts (plugs), it is also possible to use, for example, flat products wound into rolls, which have a so-called two-part winding or roll core or sleeve, which are also securely caught in the collecting means would, so a last sheet of this would be deducted from the consumption role.

Furthermore, the present invention relates to a swing arm, designed as described above. The swing arm has a holding part and a guide part, between which a hinge axis is formed, which is aligned between a front wall and a rear wall of an output device, in which the swing arm can be arranged, and transverse to a longitudinal extent of the swing arm. Particularly preferably, a joint housing is arranged between guide part and holding part of the swing arm according to the invention, which comprises the joint axis. More preferably, the holding part comprises at its upper end portion an angled holding portion, in particular as described above. Furthermore, the guide part comprises at its lower end region a widening portion, in particular as described above. For the stated angles and other configurations of the swing arm reference is made to the above statements.

Furthermore, the present disclosure relates to an output device of the type mentioned above, wherein a pressure arm is provided, which is mounted at its one end and cooperates with an adjusting means, so that in a direction of a side wall to other side wall pressure is exerted on an insertable role. The direction of the pressure, in the sense of the present disclosure, is to act as being approximately perpendicular to a plane passing through the side walls. Such an embodiment of the dispensing device advantageously makes available an adjusting mechanism which, in particular when using rolls of different widths, which are already available in terms of production, enables a fine adjustment of the holding pressure in the dispensing device, so that the rolls can be safely held, for example, in guideways in the device are provided, are guided.

The adjusting means according to the present disclosure may also be referred to as adjusting means. It serves to make it possible to adjust, in particular finely adjustable, a pressure exerted on the roller via the pressure arm. Thus, the pressure can be adjusted via the adjusting means, which acts on the pressure arm and thus on the roller. As a result, by the operator who either waits for the device or filled into rolls wound flat products, adjust the pressure with which the pressure arm exerts pressure on an insertable role on the adjusting means. Thus, in particular production-technically unavoidable differences in the width of sheet-like products wound into rolls can be easily compensated, so that they are arranged securely removable in the device. If, for example, a roll of a wound flat product having a greater width is used, then the pressure acting on the pressure arm is reduced via the setting means; if a roll of wound flat products with a smaller width is used, the pressure of the pressure arm is adjusted by adjusting the setting means; which acts on the pressure arm, increased accordingly. It is also possible to describe the mode of operation of the actuating means of the device in such a way that the action path of the pressure arm is influenced, in particular adjusted, by this adjustable and, in particular, also finely adjustable.

The pressure arm itself is located on a side wall of a roll wound flat products in operating position, that is in the filled state of Device, on. It rests against the lower roller whose flat products are removed from it by a user of the device. The pressure arm provides a secure guide in the unwinding of the sheet products, and preferably to almost a complete or almost complete settlement flat products of the role. By the pressure arm so that tilting or the like are avoided especially with decreasing diameter of the wound into a roll sheet products.

In a preferred embodiment, a contact means is arranged on an inner side of the pressure arm, which is in contact with a surface of the actuating means. By the contact means, the operation of the pressure arm is facilitated because it is on the adjusting means, which is preferably movable, in particular rotatably movable, is actuated to produce the holding pressure. An operation is carried out by the operator advantageously in an open position of the output device.

In a further preferred embodiment, the adjusting means has a Verstellgrat on its on the pressure arm towards the surface facing. The Verstellgrat is preferably annular, preferably not as a closed ring, but between its two ends a short interruption is provided. More preferably, the Verstellgrat is formed such that it has a raised end for setting a high pressure exerted by the pressure arm on the inserted role, and a flat end for setting a low pressure on an inserted role. The Verstellgrat can thus be addressed as an annular means which rises from one end, advantageously lying in a plane with a surface of the actuating means, starting up to the lofty end thereof in the form of an inclined plane. The surface of the Verstellgrats advantageously provides a guideway for the contact means, so that over the maximum height of the Verstellgrats a maximum pressure can be achieved. Typically, a maximum height of the Verstellgrats at its raised end about 1 to 20 mm, preferably about 3 mm to about 15 mm, so that differences in the roll widths of up to 2 cm can be compensated.

In a further preferred embodiment, the adjusting means on its surface facing the pressure arm an annular engagement surface, which is not necessarily designed as a closed ring, for an engagement element. The engagement surface may be formed, for example, corrugated, and preferably provides a blocking of the actuating means upon engagement of the engagement element. As a result, the adjusting means is in particular no longer rotatably movable. The engagement means may be formed, for example, finger-like with an end face which engages in recesses between individual corrugations of a correspondingly formed engagement surface. The engagement means is advantageously arranged in a wall part, on which also the adjusting means, more preferably also the pressure arm, is arranged. The wall part may advantageously be part of an insert part, which is further preferably detachably connectable to the housing part, in particular its rear wall, is formed. The insert thus forms a kind of inner wall in the device. With such a design, the printing mechanism can then be provided as a retrofit to existing dispensers. In a preferred embodiment, the engagement element is arranged on a wall part, which carries the actuating means on one side. Preferably, the engagement element is in one piece, in particular of the same material, connected to the wall part, preferably elastically connected, more preferably integrally connected elastically. The elasticity may, for. B. all be provided by the geometric design of the engagement member available. An elasticity is advantageously present in the directions of movement of the adjusting means. The engagement element can be described as a section-shaped projection, also responsive as a finger-shaped projection. The engagement element is preferably arranged in a recess of the wall part, and preferably does not project beyond a surface of the wall part facing the interior of the device. The adjusting means is advantageously arranged on the side of the wall part, which is preferably part of an insert part in the housing part of the dispensing device, facing away from the roll used.

However, it can also be provided that, for example, the pressure arm is integrally connected directly to the side wall. The elastic mounting takes place, for example, in that the pressure arm is formed at least partially from an elastic material, at least in the region of the attack of the pressure arm on the wall part, in particular in the case of a one-piece design thereof. An elasticity is also provided by the fact that the pressure arm is L-shaped and thus has a long leg, which can convey a corresponding elasticity. However, it can also be provided that springs of any kind, in particular leaf springs, are provided with which the pressure arm is supported on the wall part and / or the side wall. The end of the pressure arm, in particular the long leg of the same, which is mounted on the wall part and / or on the side wall, is advantageously mounted on the side on which the adjusting means is arranged. However, it can also be provided that the pressure arm is mounted on the side opposite the actuating means of the wall part or on the side wall.

If the wall part has a recess, which follows the outer contour of the pressure arm, the pressure arm is advantageously L-shaped, and the recess in the wall part is advantageously L-shaped. The recess is formed slightly larger than the pressure arm, so that it can swing back, for example, with a reduction of the holding pressure in the recess in the direction of the actuating means.

In a further preferred embodiment, an upper side of the pressure arm facing an inserted roller interacts with it, be it directly with the flat product or with insertion parts (plugs). The insert parts are used on both sides of the inner roll or sleeve, which can also be divided. They usually each have a cylindrical projection, but with different diameters to avoid mis-insertion of the wound into a roll sheet product in the device. The cylindrical projections are received and guided by guideways of the device, whose width is advantageously adapted to the diameter of the projections. The upper side of the pressure arm can be designed to be approximately trough-shaped, in particular in the region of the short leg in the case of an L-shaped design, and provide an additional guide track for the roller in the unwinding direction thereof. Advantageously, the pressure arm is associated adjacent to a guide track for a roller. Due to this proximity, a particularly compact design of the device is made possible.

More preferably associated with the side wall of the pressure arm opposite side of the housing part is a guide track having a larger width b ₁ than a width b _{2 of} the guide track on the side wall with the pressure arm. There may be provided plugs with different insert diameters of cylindrical projections thereof, which correspond to the widths of the first and second guideway.
