Description

Apparatus for manually or mechanically generating a tubular

packaging material

The invention relates to an apparatus for manually or mechanically producing a tubular packaging material from a wound into a roll of paper web, which forms an inner cavity, from which the paper web for forming the packaging material is peelable.

A generic packaging material dispenser is known from DE 20 2012 009 025 Ui. The packaging material dispenser comprises a receptacle with an axial holder attached to it, into which a paper web roll can be inserted. The Axialhalterung is tapered as a conical output funnel with

Internal contour realized. The recording is formed by a half-shell. At the front end of the half-shell of the rotationally symmetrical dispensing funnel is arranged with a conical inner and outer contour. At the front and rear ends of the frusto-conical discharge hopper cylindrical tube-like fixing portions of constant diameter are provided. At the front end of the discharge hopper, a toothed ring may be provided as a tear-off. In the packaging material dispenser, the raw material for the tube-like packaging material is a paper web wound into a blank, which is inserted into the receptacle and engages around the tubes. The tube has an internal cavity from which the paper web is removable to form spiral and tubular packaging material. The

Verpackungsroh raw, the half-shell, the frusto-conical output hopper and the discharge port are all arranged coaxially to each other. The well-known packaging material dispenser enjoys great popularity because it can be operated maintenance-free, is easy to use and especially for small

64 / 814,222 If the manual packaging material producing device has filled so many packages with packaging material that the paper web roll has been exhausted, the packing staff can simply reload a new roll ,

However, it has been shown that in particular inexperienced or untrained packing personnel sometimes handles the packaging material dispenser inappropriately and thereby may incur unpleasant abrasions in the area of the hands and forearms. Specifically, when loading packaging material web rolls into the receiving dish of the dispenser and withdrawing spiral packaging material web tubes from the interior cavity of the paper web roll, it may occasionally happen that users collide with the axial mount or components attached thereto, such as the cutting ring. In addition, if the paper web is improperly inserted into the receptacle or pulled off improperly, the paper web can undesirably tear or tear off, which can impair the quality of the tubular packaging material or lead to undesirably high scrap quantities.

It is therefore an object of the invention to overcome the disadvantages of the prior art, in particular to provide a device for manually or mechanically producing a tubular packaging material from a wound into a roll paper web, the use of which is simplified in particular for untrained packing personnel, so as the risk for injuries and material damage, especially when loading and unloading the paper web.

This object is achieved by the subject matter of independent claims 1, 6 and 10.

Accordingly, according to a first aspect of the invention there is provided an apparatus for manually or mechanically producing a tubular packaging material from a paper web wound into a roll forming an interior cavity from which the paper web is peelable to form the packaging material. A tubular packaging material can also be used as a be designated three-dimensional packaging material. A three-dimensional packaging material may be formed from a two-dimensional sheet web-like stock in the form of a paper web roll into a three-dimensional structure having at least one crush cavity to provide a cushioning and cushioning function. Such a crush cavity may extend in the longitudinal direction of the packaging material. In this respect can be spoken of a tube-like packaging material. The packaging material hose can be stabilized, for example embossed, or only demolished without stabilization. For example, a roller may be provided whose axial length is at least half as large as its outer diameter and / or whose axial length is at most twice as large as its outer diameter. Preferably, the ratio of axial length to outer diameter of the tubes may be greater than 0.75, in particular greater than 1, and / or less than 1.75, in particular 1.5. For example, the ratio of axial length to outer diameter of the tubes may be about 1.25. Preferably, the inner diameter of the crude can be less than half the outer diameter when new. Preferably, the inner diameter when new of the crude is greater than 1 cm, preferably greater than 5 cm, more preferably greater than 10 cm, and / or less than 25 cm, preferably less than 20 cm, more preferably less than 17.5 cm. For example, an inner diameter of a new tube may be about 16 cm.

The device according to the invention comprises a receptacle for at least partially circumferentially encompassing the tubes and an axial holder for holding a front side of the tubes, wherein the axial holder has a wall in which a dispensing opening for dispensing the packaging material is formed in a dispensing axial direction. The wall has a guide inner contour tapering in a funnel-like manner from the receptacle to the dispensing opening in the dispensing axial direction. The receptacle and the guide funnel may be formed, for example, as a thin-walled plastic part with a wall thickness of less than 5 mm, as in the device described in DE 20 2012 009 025 Ui for manually generating a spiral packaging material whose entire contents is incorporated with reference to the present application , Preferably, the receptacle may have a constant, preferably cylindrical-half shell-shaped, cross section in the course along the roller axis. A cylinder-half-shell-shaped receptacle preferably has an inner diameter that substantially (+ o ... io%) corresponds to the outer diameter of the inserted raw. In particular, the receptacle can have a constant wall diameter in the course along the roller axis respectively. Preferably, the recording in the axial direction of the roller in the dispensing direction free of a resistance, in particular free from an axial movement to the additional axial movement limitation, formed for the role. The Axialhalterung may at its opposite to the Axialhalterung end or at least by a roller length of the Axialhalterung have a fuse and / or an axial stop for holding the roller. According to one embodiment, the receptacle comprises exactly one first roll. Alternatively or additionally, the receptacle may comprise a shell body, which is in particular substantially semi-cylindrical in shape and / or which defines a receiving longitudinal axis which is preferably aligned, in particular aligned, to the dispensing direction and / or preferably corresponding, in particular aligned, to the roller axis of the roller is. The receptacle may have a shell body, for example made of plastic, in particular with a small wall thickness less than 5 mm. The shell body of the receptacle is preferably dimensioned with an inner diameter which is at least as large as the outer diameter of a roller which is provided for equipping the device. The inner diameter of the receptacle preferably measures at least 20 cm, in particular at least 25 cm, particularly preferably at least 30 cm. It may be preferred that the inner diameter of the receptacle is less than 100 cm, in particular less than 50 cm, because rollers with such a large outer diameter are impractical to handle. A shell body may also have a different shape than a semi-cylindrical shape, for example, have a V-shaped cross section or a polygonal cross section. It is also conceivable that the receptacle is formed by at least two struts extending in the direction of the dispensing direction, on which rollers can lie. A receptacle may comprise a plurality of struts extending longitudinally in the dispensing direction or transverse to the dispensing direction to at least partially enclose a packaging material web roll circumferentially. In this respect, a recording longitudinal axis can also be realized by a recording formed by rail and / or striving.

According to the first aspect of the invention, the wall is provided with at least one front axial recess at an exit axial direction front end of the axial support which extends at least 10 mm in the exit axial direction at the front end of the axial support. The in the wall with the funnel-like tapered in the output axial direction guide contour, extending from the front, narrow end of the Axialhalterung from axial recess simplified for the packaging personnel intervention into the interior of the Packaging material dispenser. It provides additional space for the user's hand and arm near the dispensing opening so that it can more easily engage the dispenser and reduce the risk of collision with the dispenser. At the same time, the axial recess can provide a tear-off that is particularly easy to operate. Due to the relatively large dimensioning of the axial recess according to the first aspect of the packaging material dispensing device according to the invention, the risk of injury to a packaging material dispenser with a ring knife or the like is considerably reduced. Preferably, the packaging material producing device is free of a cutting ring, such as a metallic ring gear. Preferably, the Axialhalterung is free of metal. In particular, the receptacle may be free of metal. Preferably, the axial holder and / or the receptacle made of plastic. The apparatus for manually or mechanically producing a tubular packaging material may have a wall provided with exactly one, two, three, four, five, six or more axial recesses. Preferably, in a device having a plurality of front axial recesses, the individual axial recesses are the same size, uniform and / or the same dimensions. The use of multiple front axial recesses improves the operability of the device from different directions.

According to a preferred embodiment of a device for manually or mechanically producing a tubular packaging material, the wall forks for forming the at least one front axial recess in the circumferential direction (ie circumferentially) and transversely to the output axial direction. Preferably, the axial recess bifurcates such that the width of the front axial recess transversely to the dispensing axial direction increases in the axial direction in the axial direction in the output axial direction. The at least one front axial recess may preferably have a narrow root area which forms the receiving side beginning of the axial recess and from which root section the axial recess widens progressively in the axial direction, preferably increasingly towards the dispensing axial direction in the circumferential direction. The front axial recess or engagement and / or tear-off recess may be shaped such that in the direction opposite to the dispensing axial direction, the dispensing axial recess becomes progressively narrower and particularly narrow in its root region to form a clamping region. In the clamping area, the tubular packaging material drawn from the inner cavity of the roll can be clamped to it by means of increased frictional resistance in portions to separate and so packaging material units for insertion into a packaging container, such as boxes to separate. A device in which the at least one front axial recess is formed with a receiving side clamping portion allows a particularly simple tear-handling of the packaging material dispenser, wherein the front end is still held in contact with the underlying packaging material in the clamping region of the front Axialaussparung after separating a packaging material section , The packaging material held in a clamping region of an axial recess can be easily gripped by the user to create a next packaging material web unit with no risk of injury, and more packaging material can be withdrawn from the inside of the reel to produce a second or further packaging material piece.

According to one development of an apparatus for the manual or automatic production of a tube-like packaging material, the at least one front axial recess defines an acute opening angle at least in a rear clamping section in the output axial direction. An acute opening angle is generally smaller than 90 ° and may preferably be less than 45 °, in particular less than 30 °, preferably less than 15 ° and particularly preferably less than 10 °, in order to ensure a strong clamping and / or tear-off function ,

According to a preferred development, which is combinable with the previous, the mutually circumferentially opposite edge edges of the wall limit the front Axialaussparung such that they curved in particular preferably continuously curved, so that the circumferential width of this Axialaussparung increases in the output axial direction in particular continuously. Preferably, the edge cords of the wall are shaped convex in such a way. The rear region of the marginal edges in the axial direction can form a small, preferably vanishing, distance between the mutually circumferentially opposite marginal edges. In the front end region of the discharge opening, the opposite marginal edges can be as far as possible from one another. The circumferential width may be defined in a plane perpendicular to the output axial direction as the shortest distance of opposite peripheral wall edges. Such rounded wall edges have a particularly low Injury potential and prevent unwanted premature tearing of the packaging material.

According to a preferred development, the front end of the Axialaufnahme be formed by continuously rounded wall edges, in particular adjacent edge edges preferably of two adjacent front axial recesses into each other continuously, preferably with constant curvature pass. In such a device, the wall sections extend between each two immediately adjacent front Axialaussparungen petal-like or beak-shaped in the output axial direction. A device for producing a tube-like packaging material according to the first aspect of the invention with exactly two front axial recesses which are arranged circumferentially by i80 ° offset at the edge of the dispensing opening and whose peripheral edges curved in the circumferential direction from a rear clamping portion in the axial direction forward curved and merge into each other, may be referred to as beak-shaped output.

According to a preferred embodiment of a device according to the invention, the guide inner contour of the wall extends starting from the front end of the axial holder in the output axial direction for receiving, preferably until immediately after the recording, in the output axial direction continuously. The continuous in the output axial direction of the inner contour of the guide is especially jump, kink and / or edge free. In particular, the guide inner contour can extend in the output axial direction in sections in a straight line and / or in sections with a curvature. The curvature extending in the axial direction has a radius of curvature which is at least 1 cm, preferably at least 2 cm, in particular at least 5 cm or at least 10 cm. With a smaller radius of curvature, in particular below 0.5 cm, a continuous course can no longer be assumed. In the axial discharge direction rectilinear and curved in the axial discharge direction sections preferably merge into each other continuously, in particular stepless, kink-free and / or jump-free. In a transition between a curved and a rectilinear portion preferably corresponds to the orientation of the rectilinear portion of a tangent at the end of the curved portion. It is also conceivable for a curved section with a first radius of curvature in the output axial direction to be preferably continuous in a curved section with a second, different, Radius of curvature passes. For example, the radius of curvature may be greater in the first curved portion than in the second curved portion. The transition region between two curved sections preferably has a curvature transition that continuously adapts from one to the other radius of curvature.

According to a preferred embodiment of a device according to the invention, at most seven axial recesses are arranged on the front end of the axial holder in the output axial direction. Preferably, at most five, in particular at most two or three, front axial recesses may be arranged at the front end in the axial direction of the axial support. In particular, exactly one front axial recess may be provided at the front end of the axial support in the output axial direction. The advantage of the invention can already be realized with only a single front axial recess. It may be advantageous to provide multiple front axial recesses to ensure easy, high quality, and quick tear off from different directions. Surprisingly, it has been found that with the provision of additional front Axialaussparungen no further advantageous change can be achieved more. On the contrary, it has proved to be disadvantageous because each additional axial recess increases the likelihood that the user does not slip into an axial recess when handling the device with the spiral paper packaging material to be torn off, but instead contacts a beak-shaped wall region between two adjacent axial recesses ,

According to a second aspect of the invention, an apparatus, which may be configured as described above, is provided for manually or mechanically forming a tubular packaging material from a raw paper web which forms an interior cavity from which the paper web is peelable to form the packaging material and defining a role axis. According to the second aspect of the invention, the apparatus comprises a receptacle for at least partially circumferentially embracing the tubes and an axial holder for holding on the tube, the axial holder having a rounding in which a dispensing opening for dispensing the packaging material is formed in an exit axial direction, wherein the wall has a guide inner wall tapering in a funnel-like manner from the receptacle to the dispensing opening in the dispensing axial direction. Contour has. In this case, according to the second aspect of the invention, the dispensing axial direction is angled relative to the roller axis. In other words, the wall, and in particular its axially forward end defining the dispensing opening, is shaped such that the dispensing axial direction is preferably at an angle relative to the roller axis, preferably through the center of the dispensing opening, in particular at right angles to the surface defined by the dispensing opening or skewed to the roll axis. As described above, the roller axis is designed according to the central axis of a preferably cup-shaped receptacle for encompassing the paper web roll. The orientation of the dispensing axial direction is transverse to the roller axis passing through the tubular inner cavity of the paper web roll, thus facilitating user intervention in the dispensing funnel and, optionally, the paper web roll interior cavity, particularly if the dispenser is positioned laterally of the user's packaging workstation. This facilitates the intervention of the user in the interior of the packaging material dispenser or the inner cavity of the tubes, so that the risk of injury during intervention, in particular when gripping one end of a fresh paper web, is considerably reduced. Preferably, no sharp-edged cutting devices, such as a toothed ring, are provided on and / or in the dispensing opening, so that a risk of injury is almost completely eliminated. It is conceivable to orient the output axial direction at a predetermined output angle relative to the roller axis when the axial support together with the tube defines the roller axis. For example, an output angle between 0 ° and 90 ° may be defined across the roller axis. Preferably, the output angle is between 5 ° and 45 °. Particularly preferably, an output angle between io ° and 20 ° can be defined. In a predetermined attachment of the packaging material dispenser to a packaging workstation, one of the above or another region may be more preferably defined for an output angle between the dispensing axial direction and the roller axis. At the front end region of the axial holder, the wall can have a collar region and / or beak tip region extending essentially exclusively in the axial direction. In particular, in such an axially extending beak tip region of the wall, the front axial recesses described above can be introduced.

According to a preferred embodiment of the device for producing a tube-like packaging material, the wall defines with the funnel-like tapered guide inner contour of a funnel axis, wherein between the funnel axis and the guide inner contour a funnel opening angle of at least 15 ° and / or at most 75 ° is clamped. Preferably, the funnel opening angle can span at least 30 ° and / or at most 60 °. Particularly preferably, a funnel opening angle in the range between 40 ° and 50 °, preferably 45 °, can be provided. The funnel axis runs centrally, preferably with respect to the guide inner contour as a rotationally symmetrical axis and / or mirror-symmetry axis, through the guide inner contour tapering like a funnel.

According to a preferred embodiment of the device, the funnel axis which is angled relative to the roller axis. As described above with regard to the first aspect of the invention, the funnel-like tapering inner guide contour of the wall can have different shapes. For example, it may be conical, frusto-conical, pyramidal, elliptical, convex or concave, etc. The funnel-like tapered inner contour may preferably be formed rotationally symmetrical and / or mirror-symmetrical in order to simplify the manufacture or assembly. A center line of the wall of the delivery hopper or its tapered inner contour can define the funnel axis. The funnel axis may be in accordance with the dispensing axial direction. The dispensing opening may be coaxial with the dispensing funnel. In a device with a funnel axis, which is transverse to the roller axis, an unintentional sliding out of the inner windings of a paper web roll can be realized to a narrowest inner diameter, which is substantially narrower than the secured inner diameter of a paper web roll, on a fully rotationally symmetrical funnel realized with coaxial orientation of the funnel. As a result, a plurality of windings and thus a larger stock of paper webs can be provided, which simplifies the use insofar as rare paper web material has to be topped up and unwanted rejects due to unintentional slipping are better avoided.

According to a preferred embodiment of the second aspect of the invention, the dispensing opening, preferably in the center-intersecting dispensing axial direction, is offset and / or angled relative to the funnel axis. In this embodiment, preferably, the funnel axis transverse to the roller axis and the output in the axial direction transverse to both the roller axis and the funnel axis arranged his. In this way, for example, with respect to a packaging workstation predetermined angular positions for paper web rolls, hopper axis and / or output material can be configured to optimally hold the packaging material raw in the receptacle against the Axialhalterung to a good forming behavior of the paper web roll in a tubular, spiral packaging material when removing the To ensure paper web from the inside of the paper web roll and / or to ensure a particularly favorable with regard to the packaging workplace orientation of the output axial direction. For example, the output axial direction relative to the hopper axis axially offset parallel.

According to a preferred embodiment of a device for manually or mechanically producing a tube-like packaging material which can be combined with the previous ones, the dispensing opening, which is preferably completely surrounded by the wall, can form a particularly circular passage surface and / or star-shaped passage surface perpendicular to the dispensing axial direction, which relative to the roller axis is arranged eccentrically. In particular, the dispensing opening may be arranged eccentrically such that the roller axis does not intersect the passage area. Such a design has proven to be particularly favorable for a good and easy removal of the packaging material from the inside of the Verpackungsmaterialpapierbahnrouge and at the same time allows to use raw with a very narrow inner cavity, without these unintentionally slide out of the packaging material dispenser.

According to a third aspect of the invention, which is combinable with the previous ones, an apparatus for manually or mechanically producing a tubular packaging material from a raw paper web which forms a cavity from which the paper web is peelable for forming a packaging material. The apparatus comprises a receptacle for at least partially circumferentially encompassing the tubes and an axial holder for holding a front side of the tubes, the axial holder having a wall in which a dispensing opening for dispensing the packaging material is formed in an exit axial direction. The wall has a guide inner contour tapering in a funnel-like manner from the receptacle to the opening in the output axial direction. The wall is provided with at least one rear axial recess at an exit axial direction rear end of the Axialhalterung, starting at the rear end of the Axialhalterung beginning at least io mm in Output axial direction extends. The rear axial recess or insertion axial recess forms a pocket-like indentation on the rear, the receiving end facing the example annular back of the wall. The insertion axial recess or rear axial recess according to the third aspect of the invention simplifies the handling of the packaging material dispenser by creating a clearance without impairing the support function of the axial support for the end face of the roller. In the free space, the user can reach into the device when inserting a fresh paper web roll to bring the paper web roll end face into contact with the inside of the Axialhalterung without his hand colliding with the Axialhalterung. In this way, both abrasions on the hand of the packing personnel when inserting fresh paper web rolls into the device are avoided, as well as damage to the paper web roll, which could occur if a user for fear of abrasions drops the paper web roll into the receptacle.

According to a preferred development of the third aspect of the invention, the rear axial recess has an obtuse opening angle in a base section which is at the front in the exit axial direction. An obtuse opening angle can generally be an angle greater than or equal to 90 °. Preferably, the width of the opening angle is in the range between 90 ° and 180 °. Particularly preferably, the opening angle is greater than 120 ° or greater than 145 °. Particularly preferably, a blunt opening angle greater than 160 ° can be selected. An obtuse opening angle in the front base portion of the insertion axial recess at the rear end of the axial support, wherein the area at which the opening angle extends, at least 3 cm wide, preferably at least 5 to 10 cm wide, allows a secure engagement when inserting a paper web roll in The interior of the Axialhalterung while avoiding a pinching or tearing hazard.

According to a preferred embodiment, the wall delimiting the at least one rear axial recess has at least one step projecting in the circumferential direction between the base section and the rear end of the axial mount. Preferably, the step is predetermined in view of a predetermined outer dimensioning of the web of packaging material. With regard to the packaging material web roll to be used, the step can be selected such that the step transversely to the roller axial direction or roller axis with central insertion of the roller axis in the receiving and fixing the Axialhalterung to the Receiving extends radially further than the outer diameter of the roller. Such a configuration is particularly advantageous when the device has two or more rear axial recesses which facilitate insertion from different directions, wherein weakening of the wall by the plurality of axial recesses is at least partially compensated by the provision of steps for supporting the roller. A rib may extend in the direction of the funnel axis, in particular on the outside in the axial direction, preferably parallel to a funnel axis. Preferably, an axial direction holder may be equipped with two, three or more ribs.

According to a preferred embodiment of a device for producing a spiral tube-like packaging material, the at least one rear axial recess has an engaging portion extending at least 10 mm in the axial direction, in which the circumferentially opposite edges of this rear axial recess in the circumferential direction not less than 50 mm, preferably not less than 100 mm apart. According to this embodiment, the axially extending rear axial recess is bounded in the circumferential direction by axially extending edges, which are preferably spaced sufficiently far apart to allow secure access by packing personnel.

According to a preferred embodiment of a device according to the first, second and / or third aspect of the invention, the device comprises at least two, three, four or more front and / or rear axial recesses. The number of front axial recesses and / or rear axial recesses may be independent of each other. In particular, the at least two (front and / or rear) axial recesses are each arranged rotationally symmetrical or mirror-symmetrical to one another, in particular with respect to the roller axis, funnel axis and / or output axial direction.

According to another preferred embodiment, which can be combined with the previous ones, and optionally relates to the first, second and / or third aspect of the invention, the at least one front and / or rear axial recess extends at least 20 mm, at least 50 mm or at least 75 mm and / or at most 200 mm, at most 150 mm or at most 100 mm in the output axial direction. In the embodiment where the output axial direction is different from the orientation of the Roll axis differs, it can be defined that the rear axial recess extends at least 20 mm, at least 50 mm or at least 75 mm and / or at most 200 mm, at most 150 mm or at most 100 mm in the direction of the roller axis. It has been found that such a dimensioning of the front and / or rear axial recess ensures a significant improvement in handling by in particular inexperienced operating personnel without impairing the stability of the device.

It is alternatively conceivable for the front and / or rear axial recess to extend exclusively in the output axial direction and / or for the rear insertion axial recess to extend exclusively in the direction of the roller axis. The wall may form at the front end of the Axialhalterung a sleeve portion or Rragenabschnitt whose base cross-section is transverse to the output axial direction constant, for example, hollow cylindrical. This basic cross section may correspond to the passage cross section of the dispensing opening. The wall may form at the rear end of the axial support a second sleeve portion which may be shaped according to the axial support. The rear sleeve portion may preferably be complementary in shape to, for example, a half-cylindrical shell-shaped receptacle.

The front, first sleeve section and / or the rear, second sleeve section can connect directly and / or in the same direction to the funnel section of the axial mount in the output axial direction or in the direction of the front axis, wherein in particular the cross section of the funnel section, the sleeve section and / or the rear sleeve section is rotationally symmetrical can be. In particular, the axial stop can consist of the funnel section and the sleeve section and possibly the second sleeve section.

Hereinafter, the same or similar reference numerals are used for the same or similar components of the different embodiments of packaging material dispensers according to the invention for ease of reading and understanding. An inventive packaging material dispenser or a device according to the invention for the manual or mechanical production of a tube-like Packaging material is generally provided with the reference symbol 1 below. The inventive device 1 for manually or mechanically producing a tube-like packaging material 2 from a roll 4 comprises as a main component a receptacle 3 for at least partially encompassing the roll 4 in the circumferential direction U and an axial support 5 for holding the end face of the roll 4.

The axial support 5 has a wall 11, in which an output opening 13 for dispensing the packaging material 2 in an output axial direction A is formed. On the inside, the wall 11 has a guide inner contour 15 which tapers in a funnel-like manner from the receptacle 3 in the direction of the delivery opening 13. The funnel-like tapering inner contour of the guide 15 defines a funnel axis T. Between the funnel axis T and the guide inner contour (15), a funnel opening angle Q is spanned here by way of example 45 ⁰ . In general, the funnel opening angle Q may range between 10 ° and 80 °, with a range between 30 ° and 60 ° being preferred. Notwithstanding the rotationally symmetric truncated cone shape with constant funnel opening angle Q shown in FIGS. 1b and 1c, a funnel opening angle Q which is variable in the circumferential direction can certainly be realized (as can be seen, for example, in FIGS. Toa-c and lia-c). It is also conceivable that the funnel opening angle Q has, for example, a funnel opening angle Q which varies correspondingly in the course in the funnel axial direction in the case of a progressive, degressive or axial sectionwise different taper. It may be preferred that the paper web wound up into a roll 4, from the inner cavity of which the paper web can be pulled off to form a packaging material 2, defines a roll axis R. It may be preferred that the roller axis R, the funnel axis T and the output axial direction A are aligned coaxially with one another, as for example in the first embodiment according to the invention shown in FIGS. 1 a to 1 d.

In the case of the preferred embodiment of a packaging material dispenser 1 shown in FIGS. 1 a to 1 c, a paper web roll 4 is held in a cylindrical half-shell-shaped receptacle 3, which is shaped substantially complementary to the outer circumference of the paper web roll 4. The receptacle 3 surrounds the roller 4 in the circumferential direction U with an overlap of about 180 °, preferably between 160 ° and 200 °. The paper web roll 4 is coreless, in particular without Pappkem, executed and has a cylindrical inner cavity of the innermost layer of the Paper web is formed. For producing packaging material, the innermost paper layer is drawn from the inner cavity of the roller 4, pulled through the funnel-shaped inner contour 15 of the axial holder 5 and provided by the dispensing opening 13 as a spiral tube-shaped packaging material 2, as shown schematically in the figures la to IC.

In the output axial direction A, a forward orientation is defined by the discharge direction of the packaging material 2, to which reference will be made below. With respect to the output axial direction A, the axial support 5 for holding the front end face 41 of the tube 4 is disposed on the front side of the receiver 3. In the embodiment shown in FIGS. 1 a to 1 c, the rear end side 4 the tube 4 looks in the direction of a back-side refilling opening side of the device 1. The receptacle 3 can be opened essentially completely on the refill rear side of the device 1.

On the underside of the receiving tray 3, a transversely to the axial direction A and transverse to the roller axis R inwardly projecting and convexly curved feed nose 45 is formed at the rear opening, extending in the circumferential direction over more than 15 ° and / or less than 90 ° , extends and on which the outside of the tubes 4 when reloading the device 1 can be placed. Thus, a linear contact area between the roller outer side and the hollow cylindrical shell body of the receptacle 3 can be avoided. The nose facilitates the insertion of the raw 4 into the receptacle 3 and avoids damage to the outside of the roller.

When inserting the raw 4 into the receptacle 3, the user is encouraged to introduce the end face 41 of the tubes 4 to the axial stop formed by the funnel-shaped guide inner contour 15 of the axial holder 5. To facilitate this or make it possible, at the rear end 53 of the axial support 5, a rear axial recess 31 is provided. As can be seen in Figures lb and ic, the rear axial recess 31 provides the user with the insertion of the raw 4 in the device for producing and dispensing packaging material 2 sufficient space to the front face 41 of the tubes 4 to the inner contour 15 of Axialhalterung 5 introduce, without causing the hand of the user who holds the tubes 4, comes into contact with the wall 11 of the Axialhalterung 5. In the embodiment of a rear axial recess 31 illustrated in FIG. 1b at the rear end 53 of the axial receptacle 5, an extension of the axial recess 31 in the direction of the delivery axial direction A or in the direction of the roller axis R / funnel axis T, which coincide here, is approximately 5 cm to 10 cm, wherein the rear axial recess 31 extends in the circumferential direction along the base region 33 by more than 10 cm. At the base region 33 of the rear axial recess, ie in the front end region of the axial recess 31, this has an obtuse opening angle β with an extension between 140 ° and 180 °. Starting from the base portion 33, the outer contour of the two circumferential edges U opposite side edges 32, 34 of the rear Axialaus- saving 31 is continuously rounded, in order to exclude a risk of injury to the user as far as possible.

Insofar as the layers 4 wound around each other are still in a state of static friction, as shown schematically in FIGS. 1b and 1c, the end face 41 of the tube 4 forms a flat or slightly conical surface (ie with an opening angle of almost 180 °) 41, which initially comes into contact with the guide contour 15 of the Axialaufnahme 5 at the onset of the raw 4 in the device 1 along its outer circumference end face. At the moment of the initial contacting of the front peripheral edge of the tube 4 with the guide contour 15 of the Axialaufnahme 5 provides the rear Axialaussparung 31 in the output axial direction or hereby coincides in the embodiment according to the figures la to ld coinciding funnel axis T or roller axis R a sufficient distance from 1 cm to about 5 cm for the user's hand.

The cup-shaped receptacle 3 may be made in one piece from a cylindrical shell-shaped, thin wall, for example made of plastic, with a wall thickness of up to 5 mm or less. It is conceivable that the receptacle 3 made of a different material, such as sheet metal. It may be preferred that the tubes 4 and the receptacle 3 are dimensioned in such a way that they are essentially complementary to one another, for example circular, and / or are formed coaxially or nearly coaxially to each other, wherein a deviation of the coaxiality of a few Centimeters, for example, 0.5 cm to 3 cm, can be tolerated. At the front end of the receptacle 3, which is in the axial direction A, the axial mount 5 preferably adjoins the preferred embodiment depicted in FIGS. 1 a to 1c immediately thereafter. The input region 30 of the axial holder 5 has a substantially cylindrical base cross section, from which the frustoconical inner guide contour 15 tapers rotationally symmetrically about the funnel axis T in the direction of the dispensing opening 13. The guide inner contour 15 runs starting from the receptacle 3 as far as the dispensing opening 13 without obstacles. The Axialhalterung 5 may preferably in one piece from a single part, for example, an injection-molded plastic part or a part made of a plurality of plastic components, consist. The Axialhalterung 5 has a wall 11, which may have a substantially constant wall thickness of 1 mm to 5 mm along the entire axial extent of the Axialhalterung 5. At the front end 52 and at the rear end 53 may be axially adjacent to the funnel-shaped portion of the wall 11, which forms the guide inner contour 15, hollow cylindrical sleeve or collar portions 51, 57 are formed, which are exclusively in the axial direction A and in the direction the funnel axis T extend. The collar 57 provided at the rear end 53 of the wall 11 of the axial support 5 can extend circumferentially along the outside of a cup-shaped receptacle 3, as can be seen for example in FIGS. 1 a and 1 c, and mounting elements for attaching the axial support 5 to the receptacle 3 include.

At the front end 52 of the Axialhalterung 5 are provided in the axial direction A, starting from the front end 52 of the wall 11 rearwardly extending axial recesses 21. In the circumferential direction U are at the front end 52 of the wall 11 evenly distributed, as seen particularly well in the figures la, four front Axialaussparungen 21 provided. A front axial recess 21 is adapted to allow the user some room to reach into the axial support 5, towards the inside layers of the roller 4, which define the internal cavity. Thus, the user can simply pull out the inner layers of the roll 4 through the discharge opening 13 and form a spiral tube-shaped packaging material 2. Furthermore, the front axial recesses 21 in the wall 11 are designed to act as a tear-off aid for separating individual packaging material units, for example packaging material cushions, from the packaging material hose 2. For this purpose, an axial recess 21 may be formed, for example, as in the detailed illustration according to FIG. According to FIG. 1 d, the front axial recess 21 or removal and / or tear-off axial recess 21 extends rearwardly in the axial direction A, starting from the front end 52 of the axial mount 5 in the exit axial direction A over at least 10 mm, preferably about 30 mm to 100 mm , At the rear end of the front axial recess 21 in the output axial direction A, this forms a narrow clamping section 23. The clamping section 23 forms the receiving-side base of the removal and tear Axialaussparung 21. In the clamping section 23, the front Axialaussparung 21 is initially designed with an acute opening angle a in the range of preferably between 5 ⁰ and 45 °. Preferably, the opening width of the acute angle a can be in the range between 20 ° and 35 °. Starting from the clamping section 23 of the axial recess 21, the wall 11 extend along a right and left leg or a right edge 22 and a left edge 24, between which the acute opening angle a is defined, in the axial direction A to the front. The marginal edges 22 and 24 face each other in the circumferential direction U. Preferably, the marginal edges may be configured to extend along a preferably continuous curvature path to the forward end 52 of the axial support 5. At the front end 52 of the axial support 5 is an example left peripheral edge 22 of a first axial recess 21, preferably continuously, in particular rounded, in the right peripheral edge 24 of an adjacent second axial recess 21 via.

In an embodiment of a packaging material producing device 1 with an axial holder 5, the wall 11 of which has two or more axial recesses 21 (for example according to FIGS. 10a to 10d), beak-like wall sections or beaks 12 are formed between the axial recesses 21. In the illustrated in the figures la to ld device 1, the wall 11 forms four adjacent each other in the circumferential direction U beaks 12, wherein between each two adjacent beaks 12 a mouth-like removal and / or tear Axialaussparung 21 is formed.

Starting from the clamping section 23 of the axial recess 21, the width w of the axial recess 21 increases in circumferential sighting U. The furthest distance W in the circumferential direction U between peripheral edges U, which are opposite each other in the circumferential direction U, is formed in the region of the front end 52, and the narrowest opening width w of the front axial recess 21 is in the receiving end region of the Formed clamping portion 23, where preferably a radius transition between the left and right peripheral edge 22, 24 may be provided.

The axial recess may be formed exclusively in the cylindrical sleeve-shaped front collar portion 51 of the receptacle 3. In such a (not shown) embodiment, the front axial recess 21 extends within the wall 11 purely axially. According to the embodiment shown for example in the figures la to ld, the tear-axial recess 21 expands both within the front collar portion 51 and in the funnel portion 55, which forms the funnel-shaped tapered inner guide contour 15. The axial recess 31 extending both in the collar section 51 and in the funnel section 55 thus extends not only in the axial direction A in the wall 11 but also transversely to the axial direction A in the radial direction Q.

Figures 2a to 2c show another embodiment of an axial support 5 for a device according to the invention for producing packaging material 1 according to a second embodiment. From the example described with reference to Figure 1, the Axialhalterung 5 differs according to Figures 2a to 2c in that in the wall 11 of the axial support 5 only a single front removal and / or Abreiß- axial recess 21 is introduced. The front collar section 51 of the axial mount 5 which extends in the circumferential direction U over a large part (approximately 270 °) of the discharge opening 13 can be seen in FIG. 2c. As in the embodiment described above, the axial recess 21 extends in the axial direction A through the collar portion 51 as well as with radial and axial components into the funnel section 55, which provides the axial support 5 with the guide inner contour 15. The guide inner contour 15 of the axial holder 5 shown in FIGS. 2 a to 2 c is essentially identical to the guide inner contour 15 of the embodiment illustrated in FIGS. 1 a to 1 d. As before, the funnel axis T and the output axis A are coaxial with each other. The guide inner contour 15 forms a frusto-conical inner side surface of the axial support 5 about the funnel axis T, which is formed from the entrance portion 30 with a circular cross section to the passage surface 20, which is also circular (except for the nose-like contour of the front Axialaussparung). (A rear insertion Axialaussparung can optionally be additionally provided in the provided in Figures 2a to 2c axial supports 5 (not shown)). FIGS. 3a to 3c show a third embodiment of an axial holder 5 according to a third preferred embodiment of a device 1 according to the invention for producing packaging material. In contrast to the two embodiments described above, in the third case, the output axial direction A is offset eccentrically relative to the roller axis R by a distance E in parallel. The funnel axis T extends at an angular offset g relative to the roller axis R.

The embodiment according to FIGS. 3 a to 3 c also differs from the previously described embodiments in that five uniformly distributed removal and / or tear-off axial cutouts 21 are provided at the front end 52 of the axial mount 5. Between the axial recesses 21, the axial support 5 forms five beaks 12. The funnel-shaped inner contour 15 of the Axialhalterung 5 according to the figures 3a to 3c is rotationally symmetrical about the funnel axis T and relative to the roller axis R and the output axis A in the form of an oblique truncated cone. Compared to the parallel orientations of output axis A and roller axis R, the funnel axis T is tilted by an angular offset g, which is between 5 ⁰ and 10 ° in the embodiment illustrated in FIGS. 3 a to 3 c. Such an embodiment of the axial stop 5 is particularly suitable for the case that the output axial direction relative to a direction extending in the gravity direction vertical direction (not shown) with respect to a horizontal direction (not shown in detail) is arranged inclined downwards, so that the windings of the roller

4 gravity exerts a pull-down and pull-out effect. The axial stop

5 can then be positioned so that the roller axis R and the Axialausgabe- direction A are not aligned but offset from one another, so that against an involuntary movement of the packaging material 2 by the action of gravity, an increased resistance is opposed by the axial stop 5. Unwanted slipping out of the paper web material of the roll 4 from the packaging material producing and dispensing device 1 can thus be avoided.

A fourth embodiment according to the invention of a packaging material dispenser or a device for manually or mechanically producing a tubular packaging material is depicted in FIGS. 4a to 4d. On the representation of a role is omitted. As can be seen in FIG. 4b, in this fourth preferred embodiment of the invention, the dispensing axial direction A and the funnel axis T are tilted coaxially with each other by an angle y or o relative to the roller axis R. The For the sake of simplicity, in the embodiment according to FIGS. 4a to 4c, no axial recesses are depicted on the front 52 or rear 53 edge of the axial holder 5, but these may optionally be present. Similar to that of the embodiments according to FIGS. 3 a to 3 c, the (angular) offset o between the output axial direction A and the roller axis R in the embodiment according to FIGS. 4 a to 4 c has the advantageous effect that even with an orientation tilted relative to the horizontal direction Roll axis R involuntary slipping of packaging material through the discharge opening 13 is prevented by the additional provided by the axial support 5 resistance.

Figures 5a to 5c show a fifth embodiment of an axial support 5. Like the axial support shown in Figures la to ld, it has four removal and Abreiß axial recesses 21 in its wall 11. In contrast to the previously illustrated embodiments is at the entrance area 30 of Axialhalterung 5 according to the figures 5a to 5c provided a substantially square input cross-section, starting from which a truncated pyramid-shaped inner contour 15 extends to a substantially square passage surface 20. The receptacle, not shown here, can optionally be formed as a semi-cylindrical shell-shaped receptacle or adapted to the square base of the axial mount 5, for example by a V-shaped cross-section or through parallel to the roller axis R supporting beams.

As can be seen in FIGS. 5b and 5c, the four axial recesses 21 are formed on the front axial support portion 51 in the delivery axial direction A and extend only in the axial direction A and in the circumferential direction U. The collar portion 51 in the embodiment according to FIGS. 5a to 5c has a square cross section. The collar portion 51 is flush with the truncated pyramid-shaped funnel portion 55. Also in this embodiment, the Axialhalterung 5 is formed with a constant wall thickness of the wall 11. The beaks 12 of the axial support 5 according to the figures 5a to 5c are flat and extend parallel to the side edges of the base or the passage surface 20 at the edges of the discharge opening 13. The clamping portion 23 is in the corner regions between the collar portion 51 and the pyramid portion 55th formed the Axialhalterung 5 and the axial recess 21 increases its width w starting from the clamping portion 23 in the course in the output axial direction A increasingly. Also at the Axialhalterung 5 with square cross-section may at the rear end of the wall 11 an insertion axial recess (not shown in detail) may be provided.

A sixth embodiment of an axial holder 5 is shown in FIGS. 6a to 6d for a further embodiment of a device according to the invention. For ease of readability 5 are shown in Figures 6a to 6d in the fully cylindrical collar portion 51 at the front end 52 of the Axialhalterung 5 no optional insertable axial recesses in the Axialhalterungen.

The Axialhalterung 5 according to the figures 6a to 6d has a stepped rear axial recess 31 extending from the rear edge 53 axially in the output axial direction A and in the direction of the roller axis R and the coaxial according to this embodiment arranged funnel axis T forward into the wall 11 extends into it. At the left edge 32 in the circumferential direction U and at the right in the circumferential direction U edge 34 of the rear axial recess 31 each have a step 35 is provided. Between the steps, a base portion 33 of the rear axial recess 31 extends over an arcuate shape over more than half of the circumferential width of the recess 31. The opening angle β is between 180 ° and 160 °, preferably 170 ° according to the plan view shown in Figure 6c. The step portions 35 form a defined approach or stop point for the frontal peripheral end of the roller 4 (not shown in detail), similar to Figure 1, from this defined approach point for the peripheral edge of the roller end face 41, starting in the output axial direction A or along the funnel axis T / roller axis R, sufficient space, ie at least 1 cm up to, for example, 5 cm, is provided for the user's hand to engage.

The step 35 is provided in the region of the transition between the frusto-conical hopper section 55 and the cylindrical sleeve-shaped rear collar section 57 of the axial support 5. The rear collar portion 57 forms part of the rear end 53 of the Axialhalterung 5 and can, as described above with respect to Figure 1, mounting components for connection to the receptacle 3 have. In particular, it is possible that the rear collar 57 of the Axialhalterung 5 is slipped over a substantially complementary shape receptacle 3 with a smaller cross-sectional width, in particular with a smaller diameter than that of the input portion 30 of the Axialhalterung. 5 With the exception of step 35, the rear axial recess 31 substantially corresponds to the embodiment illustrated in FIGS. 1a to 1c. As in the case of the embodiment illustrated in FIGS. 1 a to 1 c, the axial holder 5 has a substantially frusto-conical funnel inner contour 15, which runs rotationally symmetrically about the funnel axis T, which is oriented coaxially with the roller axis R and the dispensing axial direction A. As in the embodiment described above with reference to FIGS. 1a to 1c, the rear axial recess 31 according to FIGS. 6a to 6d does not extend only into the rear collar section 57 in the axial direction but also into the funnel section 55 with both axial and radial components forward and inward. The wall thickness of the wall 11 is also substantially constant in the embodiment according to FIGS. 6a to 6d.

The Axialhalterung 5, which is shown in Figures 7a to 7d, differs from the embodiment according to Figures 6a to 6d essentially in that in the rear end 53 of the Axialhalterung 5 two mirror-symmetrically opposite insertion axial recesses 31 are provided. The provision of a plurality of axial recesses 31 allows a simpler insertion of the roller (not shown in detail) in the receptacle of the device 1 equally from both sides laterally to the device first

In order to avoid unwanted weakening of the Axialhalterung 5 by the introduction of the rear Axialaussparungen 31 (or front axial recesses, which are not shown in detail here), preferably in parallel in the output axial direction A and in the direction of the funnel axis T extending ribs preferably on the outside the Axialhalterung 5 be provided (not shown).

The indicated in the side view of Figure 7b opening angle ß at the bottom 33 of the Axialaufnahme 31 has an opening width of more than 90 °, for example between 95 ⁰ and 120 °, so that an acute-angled contact between opposite edges 32, 34 avoided at the bottom 33 of the recess 31 is.

Between the two rear axial recesses 31, an end shield 36 is provided which extends in the circumferential direction U to less than half of the funnel axis T. At the edge 32 and 34 respectively formed opposite to the end shield 36, a step 35 is provided at the recess 31, which is similar to the above with reference to FIGS. 6a / 6d, in the transition region between receiving collar 57 and funnel section 55.

FIGS. 8a to 8d show a further variant of an axial holder 5 for a device 1 according to the invention. Similar to FIGS. 4a to 4c, the optional front axial recess and rear axial recess have been omitted for the sake of simplicity of illustration. In the embodiment illustrated in FIGS. 8a to 8c, the dispensing opening 13 is arranged eccentrically relative to the roller axis R such that the roller axis R does not intersect the through opening 20 of the dispensing opening 13. Especially for obliquely or even vertically oriented packaging material dispenser 1, such an embodiment may be preferred in order to prevent an unintentional sliding out of the packaging material from the device 1. The output axial direction A may be provided specifically with respect to a predetermined orientation of a packaging station (not shown in detail).

Opposite the roller axis R is the output axial direction A offset by an angular offset o, as the plan view of Figure 8c shows. Perpendicular to the top view 8c, there is further provided an eccentricity E between the roller axis R and the output axis A, as shown diagrammatically in FIG. 8a. The funnel axis T is parallel to the output axis A and forms relative to the roller axis R a funnel inner contour 15 according to an oblique cone.

The embodiment of an axial support 5 according to FIGS. 9a to 9d essentially differs from the embodiment described with reference to FIGS. 8a to 8d in that the delivery axial direction A is provided without the vertical eccentricity depicted in FIG. 8a relative to the roller axis R. However, an angle offset o between the output axial direction A and the roller axis R is also provided in the embodiment according to FIGS. 9a to 9d, as the plan view according to FIG. 9c shows.

Similar to the axial support 5 according to the figures la to ld has the axial support 5 in its wall 11 according to the figures 9a to 9d four removal and Abreiß- Axialaussparungen 21, which extend mainly in the front collar portion 51. As in the embodiment according to FIGS. 8a to 8d, in the embodiment according to FIGS. 9a to 9d the output axial direction A is parallel to the funnel axis T. added. In FIGS. 9a to 9d, too, the funnel axis T is angled relative to the roller axis R, so that the guide inner contour 15, which is rotationally symmetrical about the funnel axis T, has an oblique conical shape relative to the roller axis R. Nonetheless, both in the embodiments according to FIGS. 8a to 8d and in the embodiment according to FIGS. 9a to 9d, the oblique funnel retains a continuously tapering inner contour 15 with respect to the roller axis R. The rear collar section 57 of the embodiment according to FIGS. 8a to 8d and 9a to 9d extends cylindrical sleeve-shaped coaxially with the roller axis R. If a rear axial recess 31 (not shown in detail) is introduced in one of the embodiments described in FIGS. 8a to 8d or 9a to 9d would, a rotationally symmetrical configuration of the rear axial recess with respect to the roller axis R would be conceivable.

In the embodiment according to FIGS. 10a to 10c, the axial holder 5 has a substantially square cross-section for a packaging material dispensing device 1 (not shown) in the entrance area 30. The passage surface 20 at the discharge opening 13 is substantially circular with nose-like projections in the form of the front Axialaussparungen 21. As can be seen in Figure 10, the Axialhalterung 15 is provided with three uniform circumferentially distributed in the circumferential direction Abreiß- Axialaussparungen 21 which in the wall 11th are formed. The thickness of the wall 11 is substantially constant. The output axial direction A is parallel to the hopper axis T and offset by the angle o with respect to the roller axis R. The roller axis R intersects the square inlet cross-section in the opening area 30 essentially vertically. The output axial direction A is perpendicular to the passage surface 20 of the discharge opening 13. The funnel-like guide inner contour 15 in the funnel portion 55 of the Axialhalterung 5 extends starting from the square cross-section at the entrance 30 of the Axialhalterung 5 in the output axial direction A pyramid-like. The funnel or pyramid axis T is oriented obliquely relative to the roller axis R, in the axial direction of the exit in each case.

The preferred embodiment illustrated in FIGS. 11a to 11c differs from the embodiment according to FIGS. 10a to 10d by the smaller number of only two diametrically opposite axial recesses 21 arranged around the dispensing opening 13. On the other hand, the base area is in the entrance area with two right angles Side edges designed and two quarter circle connected side edges. Starting from this basic form, the inner guide contour 15 extends substantially pyramid-shaped from the entrance 30 to the passage opening 20, similar to the embodiment according to FIGS. 10a to death. The funnel axis T or pyramid axis defined by the funnel section 55 is light relative to the exit axial direction A. offset in parallel and offset from the roller axis R by the angle o. As before, the roller axis R intersects the input cross section approximately centrally and vertically. The output axis A is centered and / or perpendicular to the passage opening 20th
