An axial rear surface of a package to be conveyed Piervorratseinheit may denote the axial end face of the paper supply unit to be conveyed, which points in the direction away from the guide funnel or its opening, or opposite to the dispensing direction. For example, at least one common carrier can be provided for a plurality of paper supply units to be conveyed. Alternatively, at least one stock unit individual can be provided with each participant. In a receiving arrangement for receiving a predetermined number of paper supply units, it is conceivable that a corresponding number of each one of a paper supply unit associated driver are provided.

According to one embodiment of the invention, the driver is movable between a Alctivstellung and a passive position movable. The driver can be used in the active position for moving the at least one paper supply unit to be conveyed in the discharge direction and / or for a driving engagement with respect to the at least one paper supply unit to be conveyed, the driver engaging in the receiving arrangement in the transverse direction for holding the paper supply unit, in particular in FIG Radial direction with respect to the roller axis.

If a plurality of carriers are provided, it may be preferred that all drivers, preferably independently, movable between an Alctivstellung for moving the at least one to be conveyed paper supply unit in the discharge direction and a passive position for moving the Transportmit means against the dispensing direction or without entrainment effect which are at least one paper supply unit.

According to a development of the device, which can be combined with the previous ones, the driver can be biased in the direction of the active position, in particular by means of a spring, and / or as a body swept and / or tapered against the dispensing direction, such as a wedge or the like. The shape of the driver can be designed such that depending on the direction of movement of the carrier of the driver when hitting the at least one Papiervor rat unit automatically moves into the active position or passive position, in particular special the shape of the driver is designed such that during movement of Means of transport from the gripping position in the delivery direction to the delivery position, the at least one role is taken and / or that during a movement of the transport against the dispensing direction, the driver unfolds no Mitnahmewir effect, for example, below the at least one paper supply unit ent langleitet.

According to a further development of the device for producing a tubular Ver packaging material, the driver can be pivotable between the active position of the passive position about a relatively fixed to the transport means pivot axis. In this case, the driver can be folded in particular in the passive position. Preference, the driver in the passive position in the means of transport, by the means of transport through or next to the means of transport be depressed. With the participants may in particular be dug in, through or next to a conveyor of the means of transport, such as a pull rod, a rack, a conveyor belt, a Förderket te or the like.

According to a preferred embodiment of the device, the inner contour of the guide funnel, starting at the front end of the guide funnel in the output axial direction to the receiving arrangement, preferably until immediately following the recording, continuously in the output axial direction. The continuous in the output axial direction of the inner contour is in particular jump, kink and / or edge free. In particular, the inner contour in the output axial direction can be section-wise rectilinear 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 Axi alausgaberichtung rectilinear and curved in Axialausgaberichtung 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 straight-line Ab a tangent at the end of the curved portion. It is also conceivable that a curved portion with a first radius of curvature in the output axial direction preferably continuously merges into a curved portion having a second, different, radius of curvature. For example, the radius of curvature in the first curved section may be greater than in the second curved section. curved section. The transition region between two curved sections preferably has a curvature transition that continuously adapts from one to the other radius of curvature.

The output axial direction may be angled relative to the longitudinal direction of the paper supply unit, for example, to the roller axis or to the Leporellostapel- bottom surface. In other words, the inner contour and in particular its axially forward end defining the dispensing opening may be shaped such that the dispensing axial direction is preferably at an angle relative to., Preferably through the center of the dispensing opening, in particular at right angles to the surface defined by the dispensing opening the roll axis or skewed to the roll axis runs. The roller axis may be designed according to the central axis of a preferably cup-shaped receiving arrangement for order to grab the paper web roll. The orientation of the dispensing axial direction is thus optionally transverse to the paper supply unit paper supply longitudinal direction, for example the roller axis, which passes through the tubular inner space of the paper web roll, so that the user's intervention in the dispensing funnel and optionally the paper web roll inner cavity or the Leporellostapel top surface is simplified in particular if the dispensing device is arranged laterally of the user's packaging workstation. It is conceivable to orient the output axial direction at a predetermined output angle relative to the roller axis. For example, an output angle between 0 ° and 90 ° can be defined transversely to the longitudinal direction. Preferably, the output angle is between 5 ⁰ and 45 ⁰ . Particularly preferably, an output angle between 10 ° and 20 ° can be defined. In a predetermined attachment of the packaging material dispenser at a packaging workstation, one of the above-mentioned or another range may be particularly preferably defined for an output angle between the output axial direction and the longitudinal extension direction.

In a device with a funnel axis, which is transverse to the roller axis, an unintentional slipping out of the inner windings of a Papierbahnrol le can be realized to a narrowest inner diameter, which is much narrower than the secured inner diameter of a paper web roll, on a fully rotationally symmetrical Funnel with coaxial orientation of the funnel is realized. As a result, more windings and thus a larger paper web supply can be provided. Optionally, the dispensing opening may preferably be centered intersecting output axial direction relative to the funnel axis offset and / or arranged at an angle. In such an embodiment, preferably, the hopper axis may be arranged transversely to the longitudinal direction and the output in the axial direction transversely to both the paper supply unit longitudinal direction, such as the roller axis or the top surface, and the hopper axis. In this way, for example, with respect to a packaging workstation predetermined angular positions for Leporellostapel or paper web rolls, hopper axis and / or output material can be configured to optimally hold the paper supply unit in the up against the Axialhalterung to a good forming behavior of the paper supply unit in a tubular, spiral Packing material during removal of the paper web, for example, from the inside of the paper web roll to ensure ge 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 one embodiment of a device for manually or mechanically generating a tubular packaging material which is combinable with the previous, preferably by the wall completely surrounded Ausgaböff tion of a particular circular passage area and / or star-shaped passage area, perpendicular to the Ausgabeaxialrichtung form, 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. For example, the passage area at the discharge opening may be circular, elliptical, star-shaped or polygonal, preferably formed with nose-like projections in the form of the front axial recesses. Such an embodiment has proven particularly favorable for a good and easy removal of the packaging material from the paper supply unit and at the same time allows to use flat or narrow Le porellostapel or rollers with very narrow inner cavity, without these unintentionally slide out of the packaging material dispenser.

According to one embodiment of a device for producing a tubular packaging material, the guide funnel in its receiving-side input area, for example, a rear sleeve portion, define a substantially rectangular and / or at least partially rounded funnel base cross-section. The shape of the funnel base cross-section can be substantially constant along the funnel axis with different, depending on the funnel tapered be configured to be de-rating width. The funnel cross section may be, for example, rectangular and the inner contour of the funnel portion corresponding to the funnel base cross-section form a pyramid or truncated pyramid-shaped Innenkon structure. Alternatively, the funnel base cross-section can be cylindrical or oval, and the funnel inner contour corresponding to the circular and / or oval Tricht ergrundquerschnitts be formed frusto-conical or conical. It is conceivable that a funnel base cross-section has two, in particular, right-angled abutting side edges, which are connected at their mutually remote corners by a quarter-circular section. Alternatively, between two mutually perpendicular side edges of a funnel base cross-section and a four telkreisförmigen, opposite the tip curve portion starting from the ends of the two elongated bases, short rectilinear edge portions be seen easily.

In the preferred embodiment of a packaging material dispenser 1 shown in FIGS. 1 a to 1 d, the paper web rolls n are held in a cylindrical half-shell-shaped receiving arrangement 3 which is shaped in a substantially complementary manner to the outer circumference of the paper web roll 11. The half-shell surrounds the Rol len 11 in the circumferential direction with an overlap of about 180 °, preferably between 160 ° and 200 °. For producing packaging material, the innermost paper layer is withdrawn from the inner cavity 13, drawn along the funnel-shaped inner contour 51 of the guide funnel 5 and provided by the discharge opening 7 as spi ralschlauchförmiges packaging material.

The shell-shaped receiving arrangement 3 shown in FIGS. 1 a to 1 d, 2 a and 2 b can be produced 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 receiving assembly 3 made of a different material, beispielswei se sheet. It may be preferred that the rollers 11 and the receiving arrangement 3 are dimensioned such that they are substantially complementary to one another, for example circular, formed and / or coaxial or nearly coaxial with 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 receiving arrangement 3 in the axial direction A, in the embodiment of the guide funnel 5 shown in FIGS. 1 a to 1 d, it preferably adjoins the preferred embodiment illustrated in FIGS. The input region of the guide funnel has an example cylindrical base cross-section, from which a frustoconical guide inner contour 51 ver around the funnel axis T in the direction of the discharge opening 7 ver. The guide inner contour 51 runs starting from the receptacle 3 up to the discharge opening 7 without obstacles. The guide funnel 5 may preferably be made in one piece from a single part, for example an injection-molded plastic part or a part made of a plurality of plastic components. The guide funnel 5 has a wall which tion along the entire axial extent of the Füh 5 a substantially constant wall thickness of 1 mm to 5 mm can have. On the inside, the guide funnel 5 has a guide inner contour 57 that tapers in a funnel-like manner from the receptacle 3 in the direction of the dispensing opening 7. The funnel-like veqüngende guide inner contour 51 defines a funnel axis T. Inter mediate the funnel axis T and the guide inner contour 51 is spanned a funnel opening angle. In general, a circumferentially variable hopper opening angle can be realized. 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 embodiment shown in FIGS. 2a and 2b.

The figures la to ld each show the same device and differ in the number of existing in the receiving assembly 3 rollers 11 and in their Stel development within the receiving assembly 3 and the position of the transport 9th

In Fig. La lie in the axial direction A behind the other three rollers 11 in the Aufnahmeean order 3. The front in the output direction A roller 11 has a front end face 16, which is disposed in close proximity to the guide funnel 5. If the paper web is pulled off from the inner side 13 of the front roller 11 and discharged through the opening 7 of the guide funnel 5, a contact contact with the end face 16 can occur. When dispensing spiral-shaped or tubular packaging material through the opening 7 of the guide funnel 5, a complete or at least partial contact contact between the front end face 16 and the inner side 51 of the guide funnel are present (not shown in detail, for further explanation, reference is made to DE 20 2012 009 025 Ui).

The foremost roll 11 (Figs la, lc and ld) is in a dispensing position 50. When the foremost roll 11 has been completely unwound from the inner cavity 13 of the roll 11 by stripping the paper web and thereby consumed, the receiving assembly 3 is in position the delivery position 5 empty, as shown in Fig. Lb. The rollers 11 shown in Fig. 1b in the receiving assembly 3 are not in the delivery point 15. If the delivery position 15 is not occupied by a roller 11, as shown in Fig. Lb, a user can no longer readily produce packaging material, by pulling off a paper web from a roll 11 in receiving arrangement 3 and pulling it through the opening 7 of the guide funnel 5, in order to effect a transformation of the paper web into a packaging material. By, as shown in Fig. Tc, the transport means 9 is transported from the position shown in Fig.ib he gripping position in the dispensing position shown in Fig. Lc, a roller 11 (or more rollers 11), which is carried along by the transport means 9 , are placed in the delivery position 50. For this purpose, rear rollers 11 (FIG. 1b) can be displaced forward by at least one roller length 1 in the direction of discharge A.

In order to a movement of at least one roller ll in a receiving device 3 of an on-device for producing a tube-like packaging material, transport means 9 of very different types can be used. The trans port means may preferably be realized as a translationally movable linear conveyor, for example as a rack, conveyor belt, conveyor chain or the like. In the embodiment shown in the figures, the transport means 9 ge by a Zugstan 93 with wedge-shaped drivers 8 a, 8 b and an actuating handle 91 is realized. Such a manually operable transport means 9 may be preferred in order to realize a pos as simple as possible construction, in particular free of electronic components to reali, in particular for realizing a purely manual device for producing a tubular packaging material. Alternatively, a mechanical device could be used to produce a tubular packaging material, which may in particular be provided by a machine-assisted or motorized forming device, with a motorized transport, for example comprising an electronic actuator button for aldivating an electric drive motor, for example, a conveyor belt, a conveyor chain or the like be provided (not shown). For example, a push rod or the like for the operation of the device from behind, for example by Nachladepersonal be seen (not shown in detail)

In contrast to the embodiment of Fig. 2a and 2b is in the embodiment of FIG. La to ld, the output axial direction A relative to the roller axis R eccentric ver sets. The funnel axis T extends with an angular offset relative to the roller axis R.

In the embodiment according to FIGS. 2 a and 2 b, the output axial direction A is offset relative to the roller axis R by an angular offset. The funnel axis T runs parallel to the output axis A and forms a funnel inner contour 5 relative to the roller axis R, essentially in accordance with an oblique cone. The function of the transport device 9, as shown in FIGS. 1a-1d (as well as FIGS. 2a and 2b), will now be described. In the transverse direction Q vertically un below the receiving assembly 3 and the shell body, a guide that includes two guide sections 95, arranged. In the guide 95, the pull rod 93 is slidably mounted. At the tie rod 93 stationary carriers are stored, which are exemplified here as verschwenl bare wedges 8a, 8b realized. The transport means 9, as can be seen in Fig. Lb, designed such that for each roller 11, the arrangement in the receiving 3 remains after the front roller has been used, an individually assigned driver in the form of a respective wedge 8a or 8b provided is. It is conceivable that instead of a single, common mer driver is provided for all remaining rollers 11, which could be realized, for example, according to the driver wedge 8b.

The transport means 9 is movable by at least one roller length 1 in the direction of the roller longitudinal axis A. It may be preferred that at least one stopper is provided which, for example, can be arranged on the guide 95, the receiving arrangement 3 and / or the transport means in order to limit the linear mobility of the transport means 9 in the direction of the longitudinal roll axis R to a predetermined maximum , A stopper or a plurality of stoppers may be provided, for example, to prevent falling out of Trabsportmittels 9 from the guide 95 and / or at least one position of the means of transport, for example, the gripping development and / or to define the dispensing position.

In Figs. La, lb and ld is the transport means 9 in a rear engagement position. In this gripping position of the rearmost driver, which is realized here as hinters ter pivotable wedge 8 b, arranged with respect to the output direction A behind the rearmost roller 11 to be brought into contact with the rear end side 17 of the rear roller 11.

In Fig. 1c, the transport means, for example, by pulling on the handle 91, spent in a displaced forward discharge position to spend a previously offset to the rear roller 11 (see Fig. Lb) in the discharge position 50 (see FIG. lc). When pulling the pull rod 93 forward of the rear driver device in contact with the rear roller 11 and moves it along the roller longitudinal axis R on the guide funnel 5 to. Before the rear roller 11 lying further rollers 11 (here: a roller 11) are taken along with movement of the rear roller 11. It is conceivable that the Distance between the two shown in Fig. Lb and lc roles li greater measure be than a roll length 1 (not shown), so that a front with participants, similar to the illustrated pivotable wedge 8a, with the back of the front roller n in one Contact contact may be to take a Mitnah mekraft of the transport directly to the role n (without power transmission by movement of the role).

In the embodiments illustrated in FIGS. 1 a to 1 d, the drivers are realized as wedges 8 a, 8 b by way of example. The wedges 8a and 8b are swept counter to the dispensing direction A. The wedges 8a, 8b are pivotable about a respective pivot axis W and mounted on the transport means, here by way of example the pull rod 93. The wedges 8a, 8b are spring-biased so that they can assume an active transport position (as shown in Figure ld), in which the respective driver in the Aufnah meanorder 3 projects in order to be able to touch contact with a roller 11 to this to be able to take. At a front in the output direction A Be te a wedge 8a and 8b may be flat. The receiving arrangement 3 can have at least one access opening for at least one driver, for example a guide slot. It is conceivable that the receiving arrangement 3 has an individual access opening for each driver of the transport means 9. The spring preload of a driver, such as the front wedge 8a, may preferably be such that it is possible to move the transport against the dispensing direction A, wherein the realized as a wedge 8 a front driver no Mitnah mewirkung with respect to the rollers 11 exercises, but is disposed under the rollers 11 and slides along the outside of the roller 11 or rollers 11.

A rear dog, such as the wedge 8b, may be pivotable between an active position and a passive position to allow a roller 11 to be replenished from the rear side 105 of the packing station 10 into the receiving assembly 3 without the driver (here: Wedge 8b) is in the way (see Fig. 2b).

Figures 2a and 2b show a packing station. Similar to the packing stations known from the prior art, the schematic packing station shown here comprises a table-like support surface 104 on which shipping containers can rest in order to be filled with packaging material by the personnel standing at the front 103 of the packing station 100. The support surface 104 may be supported by a frame 101. The tray 101 carries at least one device for manually or mechanically producing a tube-like packaging material from a paper roll wound up to a roll n. The device, which is integrated into the frame 101 and carried by the frame loi, can be realized as described above. The packing station 100 is configured with a receiving arrangement 3 for at least partially circumferential gripping around at least one roller 11, in particular a plurality of rollers 11 arranged one behind the other in the delivery direction A (in FIG. 2b: three rollers 11).

At the front side 103 of the frame 101, paper for forming packaging material can be withdrawn from the inner side 13 of the front roller 11. On the rear side 105 of the frame 101, the receiving arrangement 3 can be assigned to at least one further roller 11, for example by a person other than the packing personnel standing on the front side 103.

In those embodiments of a packing station 100 shown in Figures 2a and 2b, the device is completely below the frame top 107 of the frame 101 is arranged. The frame 101, as can be clearly seen in Fig. 2a, forms a tunnel-like shaft through which the receiving arrangement 3 of the device extends. In this case, the receiving arrangement 3 or the roller axis R can extend substantially horizontally through the frame 101. In particular, the inclination of the receptacle or the roller axis is less than ± 10 ° or less than ± 5 ⁰ inclined with respect to a horizonta len. An as horizontal as possible extension of the roller axis R makes it possible to transfer the weight of a roller 11 evenly and / or over a large area from the underside of the roller (s) 11 to the receiving arrangement 3, which is gentle for the paper material. At the same time allows a horizontal arrangement of the receiving assembly 3 and / or the roller axes R a relatively large control over the position and the positioning of the rollers 11 in the receiving position 3, so that the roller (s) 11 can not slip by gravity.

Recording arrangements can also be formed differently than the receiving arrangement 3 with a half-shell-shaped body. For example, a Aufnahmeanord tion 3 ', as shown in Fig. 3, from parallel to the roller axis R aligned Stre ben or ribs, for example, at least 2, at least 3, at least 4 or more struts be formed on the at least one roller 11 rests , In the alternative embodiment of a receiving arrangement 3 "according to FIG. 4, the receiving arrangement 3" is a wave-like bent plate 33 which forms a curved receiving section. has cut, which corresponds approximately to the curvature of the outer peripheral surface of the rollers li and can extend over a width of 6o ° to 120 ° along the outside of a roll li.

5 a shows a perspective view of an alternative embodiment according to the invention of a device 1 * for producing a tubular packaging material as from a paper supply unit in the form of a paper web folded and stacked into a fanfold stack 1 *.

Like the device 1 described above for producing a tube-like packaging material from a paper supply unit in the form of a paper web wound up to form a roll, the device comprises 1 * as the main constituent of a receiving arrangement 3 * (or according to FIG. 7: 3 **) for at least partially circumferential Umgrei fen at least one Leporeflostapels, a guide funnel 5 with an opening 7 for dispensing the packaging material from a dispensing position 50 arranged stacking unit 11 * and a movable transport 9 for moving the at least one Leporellostapels 11 * in the output direction A.

A Leporellostapel is usually substantially cuboid with a height h, a length 1 and a width b. The upper side 13 * or the usually paral lele bottom 14 * of the Leporellostapels 11 * define each a flat surface (Pb). The Leporellostapel 11 * may preferably, as exemplified, be substantially cuboid, wherein the front end face 15 and the rear end face 17 (b * h) are oriented in the output axial direction A and wherein side faces (without reference character, Ph) in the longitudinal direction L the Leporellostapels or the paper web or We sentlichen in output direction A extend. The device 1 * according to FIGS. 5a and 5b differs from the device 1 according to FIGS. 1a to 1d essentially only by the type of paper supply unit accommodated and the shape of the receiving arrangement 3 or 3 * adapted therefor.

In Fig. 5a and 5b, the transport device 9 is provided as a pull rod 93 laterally adjacent to the receiving assembly 3 * (stable as shown in FIG. La to ld below the Aufnahmeeanord tion 3). It is conceivable that the transport means 9 is arranged in the embodiment shown in Fig. 5a and 5b below the receiving arrangement 3 *. For the operation of the device 1 * reference is made to the description in Fig. La to ld and 2a and 2b, since in the device 1 * practically the same operation is rea lisiert as in the embodiment described above.

The packaging material is preferably drawn from the upper side 13 * of the stack 11 * in the case of a Leporello stack (ii *) -shaped storage unit. It is conceivable for the paper web to be pulled off the front end face 5 of the stack 11 * if, for example, the stack 11 * were oriented vertically downwards in the vertical direction with the folded edges of the successive layers of the fanfold stack.

The packing station 100 shown in perspective in FIG. 6 essentially corresponds to 100, wherein, instead of the device 1 described above for receiving a roll-shaped paper supply unit, a device 1 * is provided for receiving leporello stack-shaped storage units.

Fig. 7 substantially corresponds to Fig. 3, wherein the receiving arrangement formed by two struts 3 ** is provided for receiving the leporellostapelförmigen pre ratseinheiten. As shown in Fig. 7, the struts with square cross-section may be formed, and form a strut top, which may be oriented substantially in alignment with the bottom 14 * of Leporellostapels 11 *. It is clear that the struts in the receiving arrangement 3 ** as shown in Fig. 7, may also have a different cross-sectional shape, such as a round cross-sectional shape, or that a Leporellostapel 11 * as starting material and a different kind Aufnah meanorder, for example, the semi-cylindrical Recording arrangement 3, which can be provided by two oblique struts formed receiving arrangement 3 **, or even a formed by a corrugated sheet receiving assembly 3 **. It is likewise conceivable for a paper supply unit in the form of a roll 11 to be accommodated in a receiving arrangement with a substantially rectangular cross section, such as the receiving arrangement 3 ** shown in FIGS. 5a and 5b, or on the parallel, flat struts of the receiving arrangement 3 *. * as shown in FIG. 7.
