Definitions
- the invention relates to a refill for a dispenser, in particular a sanitary dispenser for dispensing toilet paper or paper towels. Furthermore, the invention relates to a storage unit for such a refill and finally also to a dispenser for sections of a refill with a material web wound into a roll.
- the dispenser is a device that can preferably be mounted on a wall and has a housing for holding refills with a material web wound into a roll.
- the dispenser typically has a guide track inside that leads from an upper insertion position to a lower dispensing position. Bearing pins protruding from the refill are guided in this guide track. In the dispensing position, the refill can rotate to unwind material and dispense it from the dispenser in sections.
- Refill A refill is a material web wound into a roll, especially one made of paper. Bearing pins protrude from both sides of the refill, over which the refill is rotatably mounted.
- Bearing journal The bearing pins protruding from the refill serve to rotatably support the refill in the dispenser.
- Axle carrier The axle carrier is connected on the one hand to the material web wound into a roll and on the other hand carries the bearing pins protruding over the roll.
- axle supports There are at least three types of axle supports: - An axle support that extends essentially through the roller of the refill. Such an axle support is called a support bar.
- Storage unit A bearing unit is a structural unit consisting of an axle carrier and a bearing journal, which can be inserted as a whole into a refill.
- Dispensers for material webs wound into rolls are known in a wide variety of designs.
- the material webs are mainly paper, in particular sanitary or hygiene paper, household paper, etc., but also plastic or metal foils.
- the dispensers often have opposing walls in which guide tracks are provided from a filling point at least to a dispensing position, and if necessary further into a collecting chamber for empty storage units that hold the rolls.
- a new refill is therefore inserted into the two guideways using the two bearing pins of a bearing unit and then generally slides downwards into the dispensing position under the influence of gravity. If the bearing pins are located at the ends of a support rod, the empty support rod falls further down into the collecting chamber after the roll has been used up and can be removed from there.
- both the two guide tracks and the two bearing pins are designed differently to prevent incorrect insertion.
- coding The correspondence of the opposite pair of elements consisting of guideway and bearing journal is called coding, and known codings include, for example, the diameter of the bearing journal and the gap width of the guideway, a bearing journal with a bearing groove and webs engaging in this on the guideway, parallel non-rotating surfaces on the bearing journal and on the guideway, etc.
- the support rod (bearing unit) described there for a material web wound into a roll has a bearing pin that is rotatably mounted on the rest of the support rod.
- a device in the simplest case a rib that engages in a groove in the bearing pin
- an "incorrect" support rod is used, in which the relative rotatability between the bearing surface and the rest of the support rod is not given, the roll cannot rotate in the dispensing position and the dispenser is blocked. This function is referred to as "rotation coding”.
- the object of the invention is to provide a further coding option for a dispenser, a refill or an associated storage unit.
- the essence of the invention is that a bearing pin of the refill or the bearing unit of the refill is mounted so as to be axially displaceable, which makes axial coding possible: Only refills or bearing units for such refills that have such an axially adjustable bearing pin function properly in a suitably designed dispenser, while refills or bearing units Without such axial displacement, no output of the material web is possible.
- This axial coding can also be combined with a rotary coding according to the WO 2013/123536 A2 be combined.
- Bearing units for refills with an axially adjustable bearing journal are already known, for example from the GB2362375A
- the bearing pin can be pressed axially into a bearing unit designed as an end cap in order to enable the refills to be packed in a transport box in a more space-saving manner.
- An axial coding in the sense of the invention which makes it possible to release or block certain refills depending on the axial displacement of the bearing pin, is not disclosed in this prior art.
- the bearing pin can be more easily grasped in a testing device of the dispenser and moved to check the axial coding.
- the axial length of the roll which corresponds to the width of the material web, preferably corresponds to the free space between the walls of the dispenser from the insertion position to the dispensing position without any significant axial play. Since the sections of the guide track that are offset in the direction of the roll axis, i.e. in the direction of the axial length, mean that the length of the bearing pin guided by the guide track that protrudes from the roll must change if the non-axially movable roll is to move to the dispensing position, only refills that have an axially movable bearing pin can be used.
- the axial offset in the guideway and the variable length of the protruding bearing journal which can follow the offset, allow a new type of coding (axial coding), and may also increase known coding variants by another design.
- a support rod is preferably made of two parts, and the two parts can be moved telescopically into one another. However, a support rod can also be made of one part if one area is designed like an accordion.
- a section is formed in each of the two guideways that is offset in the direction of the roller axis.
- the lengths of the bearing units must increase or decrease, whereby in a third possibility the distance between the two guideways can remain the same if the two sections are offset in the same direction.
- the opposing sections of the two guideways are offset in opposite directions, this preferably means an increase in the distance between the two guideways, so that each bearing unit has to be lengthened, in particular by pulling out the bearing journal.
- the sections are offset from one another, so that both bearing journals have to be shortened.
- This design has the advantage that the guideways and the bearing journals are only pressed against one another, and no measures are required to enable the bearing journals to be pulled out, for example undercut slots or grooves as guideways and grippable end sections on the bearing journals.
- a preferred embodiment provides for the offset section to be provided near the insertion position. This means that the axial displacement of the bearing journal is required right at the beginning of the guideway, and an incorrect refill with a rigid bearing journal can be easily removed again.
- the offset section is provided close to the dispensing position. This solution makes it more difficult to remove incorrect refills, but also protects the dispenser from damage caused by the use of force to press an incorrect refill into the dispensing position, since this is generally not directly accessible from the insertion position.
- a preferred embodiment of the invention provides that a second, axially offset section is provided between the dispensing position and the collecting chamber, in which the distance between the two guideways is changed again, in particular further increased relative to one another.
- a second increase leads to the two parts being pulled completely apart, and thus each part is smaller than the support rod. This makes it easier to remove the smaller parts, as well as to dispose of them, especially if material that decomposes in water is used for the support rods.
- the second axially offset section can be provided, preferably below the dispensing position, in the same guideway as the first offset section or in the opposite guideway.
- the support rod can also be shortened again and displaced from both guideways by a ramp or the like formed in the guideway.
- both bearing pins are preferably designed to be grippable from behind.
- Bearing pins such as those described in the above-mentioned EP1 927 308 and which are provided at the end with a flange with a front groove formed by a circumferential groove in the bearing journal.
- Support rods that can be changed in length and that can pass through a guideway of a dispenser with an axially offset section can preferably already be extended from a transport position in the insertion position.
- the support rod In the transport position, the support rod essentially corresponds to the axial length of the paper roll and thus has ideal conditions for the layered arrangement of the refills with support rods in packaging boxes, since the bearing pins are sunk into each roll. From this transport position, the bearing pins are pulled out to the defined inner end position required for the insertion position and their axial projection is changed as described above when passing through the offset sections.
- the two parts of the support rod can also be separated as soon as the first offset section of the guide track passes immediately after the insertion position, as the roll in the dispenser is also sufficiently supported by the two parts of the support rod that no longer engage with one another. After the paper has been used up in the dispensing position, the separated parts fall downwards from there.
- a further preferred embodiment can provide that the two parts of the support rod can no longer be joined together to form a support rod with variable length bearing pins after they have been separated from one another, or can only do so with great expenditure of time.
- spreading or breaking-off elements, tabs or the like can be formed from the ends or edges of the two parts opposite the bearing pins, which make joining together and telescopic displacement at least extremely difficult.
- each guide track can be designed as an undercut or non-undercut groove, or a slot that can be gripped behind or not behind in the wall of the dispenser that guides the roll, or as a protruding web, with both bearing pins having the corresponding end areas that ensure the axial outward or inward movement in the guide tracks.
- the bearing pins can therefore have grooves in the end faces, end flanges with an enlarged diameter or circumferential grooves that form end flanges.
- the invention not only includes a refill or a storage unit with at least one axially adjustable bearing pin but also dispensers which are suitable for receiving such storage units or refills.
- a guide track with a transition curve is provided that changes the axial projection of the bearing pin. This transition curve therefore attempts to move the bearing pin axially. If this succeeds, the coding is OK and the refill can reach the dispensing position or enable the material web to be removed there by turning the refill. If the bearing unit or the refill is designed in such a way that there is no axially adjustable bearing pin, no dispensing takes place, for example if the support rod gets stuck in the transition curve.
- a dispensing system is provided with a dispenser for sections of a refill and with at least one refill with a material web wound into a roll, wherein the refill has at least one bearing pin which can be guided in a guide track of the dispenser from an insertion position to a dispensing position, wherein the refill is rotatably mounted in the dispensing position, wherein the dispenser has a testing device for checking the axial displaceability of the bearing pin relative to the roll of the refill, and wherein the dispensing of sections of the material web is released or blocked depending on the axial displaceability of the bearing pin.
- the axial coding can be checked using such a test device. If the bearing pin can be moved axially relative to the refill roll, the refill is correctly coded and dispensing is possible. Conversely, if such axial movability is not present or not present correctly (incorrectly coded refill), the dispensing of the material web is prevented. There are various ways of doing this: for example, an incorrectly coded refill can be stopped on the way from an insertion position to a dispensing position before it reaches it. However, it is also conceivable to prevent the rotation of the refill in the dispensing position, and thus the dispensing of the material web, if the axial coding is not correct. Other ways of preventing the dispensing of the material web in the event of incorrect axial coding are also conceivable and possible.
- the bearing pins 12, 13 are provided at the ends of an axle carrier which is designed in particular as a support rod 11.
- a barrier formed by an axially offset section 5 is formed near the insertion position 6 at the beginning of at least one guide track 4, which can only be overcome by changing the length of the projection (i.e. by axial displacement) of the bearing pin 12 engaging in this guide track. If a refill is used with the wrong support rod (without an axially displaceable bearing pin), the roll cannot pass through the offset section 5 because the wound material web cannot be pushed back and forth between the walls 3.
- Fig.2 shows a schematic sequence of inserting a roll 10 into a dispenser 1, of which only the walls 3 and the guide tracks 4 are shown in dotted lines, with the guide track 4 shown on the right containing two offset sections 5.
- the roll 10 contains a support rod 11, which consists of two axial, telescoping parts 16a, 16b, each of which has a bearing pin 12, 13 protruding from the roll 10.
- the bearing pin 12 on the right in the drawing has an end section 18 that can be gripped behind, for example a flange, which can be inserted into the guide track 4.
- the second bearing pin 13 can be cylindrical, with the associated guide track being formed by a simple groove. As in Fig.4 described, but the second guideway and the second bearing pin 13 can also have the same or different features.
- a roller 10 with the support rod 11 protruding on both sides is to be inserted into the dispenser 1, the correct alignment must first be ensured, i.e. the bearing pin 12 provided with an end section 18 that can be gripped behind must be inserted into the guide track 4 provided with the offset sections 5.
- the top illustration in Fig.2 indicates the insertion position 6, from which the guide track 4 extends at least to the dispensing position 7, preferably even further into a collecting chamber 8 for empty support rods 11.
- the offset sections 5 of the guide track thus represent an example of a test device with which the axial coding of refills can be checked.
- a measure not described in detail here prevents part 16a from being displaced and the bearing pin from slipping out of the guide.
- the guide track continues again in the original line following the offset sections 5, and the further path to the dispensing position 7 is free as soon as the part 16b and the bearing pin 12 are pushed back into the starting position.
- a support rod that cannot be moved in the roll and has a bearing pin that cannot be extended or axially adjusted cannot pass through the offset sections 5 of the guide track 4 because the roll is prevented from axial displacement by the walls 3 of the dispenser. An incorrect roll inserted in this way can only be removed again from the insertion position 6.
- Fig.3 also shows a schematic process similar Fig.2 , the most important difference being that the guideway 4 shown on the right has two offset sections 5, the first of which is near the insertion position 6 and the second is provided just before, in or after the dispensing position 7.
- the dispensing position 7 is indicated by the dash-dotted axis 14 of the roller 10, to which the second offset section 5 is connected.
- the process up to the dispensing position 7 is as Fig.2 described.
- the empty support rod 11 is moved further down the guide by gravity or by a new roll or refill and preferably reaches the aforementioned collecting chamber 8. On the way there, the empty support rod 11 must pass the second offset section 5 in which the two parts 16a and 16b are pulled completely apart and can therefore be removed individually and are of a significantly shorter length than the original support rod.
- the two parts can also be disposed of in the sewage system, since the length of the two parts is now so short that they can pass through normal sewage pipes.
- Fig.4 shows a variant of Fig.3 , in which the two offset sections 5 are distributed over both guideways 4.
- the first offset section 5 of the right guideway 4 is again close to the insertion position 6, and the second offset section 5 in the left guideway preferably after the dispensing position 7.
- half of the support rods also fall into the collecting chamber 8.
- Both bearing pins 12, 13 have end sections 18 that can be gripped behind and slide in correspondingly designed guideways 4, which prevent accidental exit from the guideway when passing the two offset sections 5.
- Fig.2 , 3 and 4 show schematically two-part telescopically movable support rod parts 16a, 16b, which are provided with one or two engaging bearing pins 12, 13, the projection of which from the roller 10 is variable.
- Fig. 5 to 8 show in detail the engagement of a groove 19 of the support rod 11 formed on the bearing pin 12 in a guide track 4 according to Fig.2 , in which two offset sections 5 are provided so that the sections of the guideway 4 above and below are aligned parallel to each other.
- the two offset sections 5 merge into each other in a wave-like transition curve (eg in an Agnesi curve).
- the guide track 4 has a cross-section which, starting from a U-shape, is provided with two webs 21 pointing inwards at the free ends of the legs and with the web 20 standing upright in the middle parallel to the two legs. Only one part 16b of the two axially displaceable parts 16a, 16b of the support rod 11 is shown.
- the Fig. 5 and 8 show two support bars 11 or their parts 16b directly one after the other in order to make the axial displacement v during the passage of the offset sections 5 more clearly visible.
- Fig. 9 to 11 show sections of toilet paper dispensers from the rear side (not shown), which can be attached to a wall or the like. Parts of the walls 3 of the dispenser 1 are shown, whereby in the drawing there is a simple slot in the left wall 3 as a guide track, into which a cylindrical bearing pin 13 engages.
- the second guide track 4 in the right side of the drawing is cut lengthwise for the sake of clarity, and its cross section corresponds to the negative of the end section 18 of the bearing pin 12, as described above, which forms a flange that can be gripped behind and is provided with a front groove 19 in which the web 20 of the guide track 4 slides.
- the bearing pin 12 is arranged with the part 16b rotatably in the part 16a, so that the roller 10 with the part 16a of the support rod can be rotated at any point in the guide tracks 4 about the axis of rotation 14, even if the part 16b or its bearing pin 12 with its groove 19 is held in a rotationally fixed manner on the web 20 in the dispenser (additional rotary coding).
- Fig.9 shows in the dispensing position 7 of the roll a position of the bearing pin 12 in which the front groove 19 is approximately horizontal. As can be seen from the width of the cut surface of the web 20, this ends just above the dispensing position 7 and the end section 18 of the bearing pin 12 can rotate as desired here.
- part 16b When passing through the two offset sections 5, part 16b is pulled outwards, while part 16a remains in place, as it is prevented from doing so by the winding of the paper.
- the axial extension of the bearing pin when passing through the first offset section 5 is visible in the support rod, which is only indicated.
- the letter v indicates the size of the outward offset, which is preferably greater than the depth of the opposite guide track 4. In this case, a support rod that does not fit because it cannot be extended would be pulled out of the second guide track, blocking the dispenser (axial coding) and preventing the material web from being dispensed.
- Fig.10 is a similar view as in Fig.9 shown, but the lower part of the dispenser has been omitted.
- two support rods 11 are drawn one after the other, the upper one of which is again shown in section just after the insertion position 6.
- the pin-shaped bearing pin 13 on the left side of the support rod 11 in the drawing is spring-mounted in a hole and the spring 17 presses the bearing pin 13 outwards into the guide track 4.
- the other bearing pin 12 in turn has the specially shaped end section 18 with a front-side groove 19 and interacts with the guide track 4 on the right in the drawing.
- a rib 21 is formed in the guide track 4 on the right, through which the bearing pin 13 is pressed against the spring 17 into the support rod 11 when the bearing pin 12 is pulled out as described above when passing the offset section 5.
- the spring 17 ensures that the bearing pin 12 remains pressed back into the guide track 4 when the roll 10 moves downwards into the dispensing position 7 and the rib 21 is overcome.
- Fig. 11 shows a similar view as Fig.9 and 10 .
- the part 16b in turn carries the bearing pin 12 with the end section 18, which is pulled out of the part 16 by the offset v when passing the offset section 5.
- the further section of the guide track 4 downwards into the dispensing position 7 runs in the offset plane, so that the part 16b can no longer be pulled out any further and the projection of the bearing pin 12 cannot be increased any further.
- the guide track 4 comprises a second section 5, which is again offset outwards and which the empty support rod 11 must pass through once the paper has been used up.
- Fig. 11 corresponds roughly to the scheme of Fig.4 .
- FIG. 12 another schematic sequence of inserting a roll 10 into a dispenser 1 is shown, of which walls 3 and the guide tracks 4 are again shown.
- the distance between the two guide tracks 4 is greater than immediately before the dispensing position, where the section 5 is offset inwards.
- the bearing pins 12, 13 end cylindrically without special engagement elements, since the bearing pin on the right in the drawing is pressed further into the roll when the offset section 5 passes.
- a spacer can be provided between the two parts. 16a and 16b, a spring, a compressible foam insert, or the like may be provided.
- a dispenser for sections of a material web wound into a roll in particular a paper dispenser, a roll 10 with the wound material web is guided axially between mutually parallel opposite walls 3 from an insertion position 6 into a dispensing position 7.
- the roll 10 has axially projecting bearing pins 12, 13 on both sides, and both walls 3 are assigned guide tracks 4 for the roll 10.
- On at least one side of the dispenser at least one offset section 5 is formed in the guide track 4, during the passage of which the axial projection of the bearing pin 12, 13 is changed during the path of the roll 10 guided between the walls into the dispensing position in the direction of the roll axis 14.
- FIG. 13a The embodiment shown shows a refill for a dispenser with a material web 15 wound into a roll 10, wherein the bearing pin 12 is mounted so as to be axially adjustable.
- the left bearing pin 13 is firmly connected to an axle carrier (support rod 11).
- the axially adjustable bearing pin 12 has an inner stop 12a, which works together with an inner counter stop 11a of the support rod. When the stop 12a rests against the counter stop 11a, the defined inner end position of the bearing pin 12 is reached. In this end position, it or the head 12b of the same, which is provided with a radial groove 19, still protrudes beyond the roller 10 and can thus be easily detected by a testing device in the dispenser (not shown here).
- the radial groove 19 is in the Figure 13 shown again in a schematic front view at the top right.
- the right bearing pin 12 is adjustable between a defined inner end position and a defined outer end position and protrudes axially over the roller 10 in both end positions.
- the outer The end position is defined by the stop 12a striking the counter stop 11b.
- the axial stroke is designated with v. It is preferably 3mm to 30mm, in particular 5mm to 20mm.
- the advantageous diameters of the support rod 11 are between 0.5 cm and 3 cm.
- Fig. 13a The construction shown can be used to create an essentially two-part axle carrier, of which a bearing pin 12 can be axially displaced by the amount v and is simultaneously held captive between the two end positions. It is clear that the Fig. 13a This is a schematic representation. The mounting of the bearing pin 12 in the axle carrier can of course be improved in practice by means of suitable sliding guides and fits.
- the embodiment with an axle carrier connected to the roll 10 allows the latter to be anchored stably in the material web 15, which is wound up into a roll.
- Radially protruding projections 24 can be provided for anchoring, which in the case of the Figure 13a shown embodiment are wing-shaped. Such a design allows the support rod 11 to be pressed axially into the already wound material web. After pressing in, the projections 24 ensure that the axle carrier is held in the roll 10 in a rotationally fixed manner and cannot be axially displaced even when the usual forces occur.
- the relatively loose axially displaceable coding part is formed by the bearing pin 12, which can be moved in a defined manner between two end positions.
- a material web 15 which is advantageously wound into a coreless roll 10 and thus allows the winding of a long material web for a given outer diameter.
- the axle carrier is designed as a continuous support rod 11 which extends essentially through the entire roll 10, with bearing pins 12, 13 protruding on both sides. This allows good and precise storage, in particular of coreless wound material webs.
- axle supports are provided, namely a left and a right end cap 18, which are clamped into the cylindrical cardboard core from the outside.
- the material web 15 is then wound around this cardboard core 9 to form a roll 10.
- the left end cap 18 is of standard design and has a bearing pin 13 integrally connected to it.
- the right end cap 18 is specially designed according to a preferred embodiment of the invention. It carries an axially displaceable second bearing pin 12, which is similar to the bearing pin in Fig. 13a can be moved axially by the distance v. Again, this is a schematic drawing. The exact positioning of the bearing pin 12 in the end cap 18 on the right can of course be designed somewhat differently in order to meet the requirements when used in a dispenser.
- FIG 13c again shows a possible bearing for a coreless wound material web.
- axle supports which in this case are designed as holding tips 43, which are pressed into the coreless wound roll 10 at opposite ends.
- the relative axial displacement of the bearing pin 12 on the right is realized similarly to the embodiments according to Fig. 13a and 13b .
- the axially displaceable bearing pin 12 is axially displaceable between two defined end positions, an inner and an outer one, which are defined by stops, but is ultimately held captive.
- a rotary coding is also provided, in which the bearing pin 12 on the right relative to the roller 10 or the axle carrier is not only axially displaceable, but also rotatably mounted.
- the groove 19 in the head 12b of the right bearing pin 12 enters a web 20, as is the case, for example, with the Fig.5 shows.
- the entire bearing pin 12 is thus held non-rotatably and would prevent the rotation of the roll 10 in the direction of the unwinding arrow 25.
- Only through the rotatable mounting (and this is the realization of the rotary coding) of the bearing pin 12 on the axle carrier can the material web be unwound in the direction of the unwinding arrow 25 despite the rotationally fixed holding of the bearing pin 12.
- this can simply rotate in a guideway of the dispenser (not shown here). It is sufficient if on one side in the Fig. 13a, 13b, 13c on the right the axial coding and the rotary coding are realized.
- the rotation of the (right) bearing pin 12 relative to the roller 10 can also be achieved by the axle carrier being held in the roller in a sliding manner - as far as the rotation is concerned.
- Better anchoring is achieved, however, if the axle carrier is connected relatively firmly to the roller and the possibility of rotation of the (right) bearing pin 12 is achieved by it being mounted so that it can rotate relative to the axle carrier and being held rotatably in it.
- the material web can be used in a sanitary dispenser, preferably a toilet paper with a tear-off perforation.
- the material web is a towel paper - preferably without tear-off perforations.
- paper material webs In addition to paper material webs, other material webs such as cling film or other plastic films can also be considered. Even metal films, particularly aluminum foil, can be wound into a material web and used in the invention.
- rolls wound around a cardboard core 9 can also be used which are not coreless but still do not have a separate cardboard core 9. Then the end caps 18 are simply inserted directly into the cavity of the material web roll or the material web roll is wound around the end caps 18.
- the rotary coding is realized by a non-rotationally symmetrical design of the head 12b of the bearing pin 12, wherein the groove 19, which runs radially, imparts the non-rotationally symmetrical shape.
- Fig. 14a to 14c In the embodiment shown, the conditions are essentially the same as in the embodiments according to the Fig. 13a to 13c Only the design of the head 12b of the bearing pin 12 on the right is different, with a square (or generally polygonal) head being provided instead of the groove 19. This can also be easily held in a rotationally fixed manner in a dispenser (not shown) or its guide track.
- the head 12b of the bearing pin 12 is rotationally symmetrical and can thus rotate in the direction of the small arrow 26 in the dispenser. It is therefore not necessary and in this embodiment preferably not provided for that the bearing pin 12 can rotate relative to the axle carrier.
- Rotary coding is not provided for in this embodiment. This rotary coding is preferably possible for the inventive concept, but is not necessary. It is sufficient if at least one of the two bearing pins (here the right bearing pin 12) is mounted so as to be axially displaceable in order to enable the inventive concept of axial coding.
- FIG. 16a and 16b The embodiment shown is an embodiment of a bearing unit according to the invention, in this case on the left side of a schematically indicated roll 10, consisting of a wound material web 15.
- the bearing unit itself has an axle carrier, which can be inserted, for example, into a cardboard core 9 of the roll 10.
- Small end stops 11c which are formed by a radially projecting flange, prevent the axle carrier designed as an end cap 18 from being inserted too deeply into the roller 10.
- Fig. 16a the defined inner end position I is shown, in which the head 12b of the bearing pin 12 still protrudes over the front side of the roll 10 (wound material web 15).
- This inner end position is defined by flange-shaped stops 12a and counter-stops 11a. This means that the bearing pin 12 cannot be pushed further inwards by these stops 12a and 11a. However, it can be pushed outwards in the direction of arrow 42 to implement the axial coding according to the invention, namely by the distance v, in order to reach the outer end position A, which in the Fig. 16b
- This outer end position is also defined by similar stops and counter stops.
- the invention relates not only to a refill, but also to a bearing unit for such a refill, wherein the bearing unit has an axle carrier which can be inserted into a material web 15 wound into a roll 10 and is mounted axially displaceably relative to at least one bearing pin.
- bearing units are shown, for example, in the Fig. 13a to 15c shown on the right and can also be sold separately without the material web 15, which is wound into a roll 10.
- the Fig. 17a and 17b show an alternative embodiment of a bearing unit according to the invention, in which the bearing pin 12 surrounds the axle carrier instead of being inserted into it, as is the case in the embodiment according to the Fig. 16a and 16b is shown.
- the Fig. 17a shows the inner end position
- the Fig. 17b the outer end position. Both end positions are defined by stops and counter stops.
- FIGS. 19a and 19b show two further embodiments which are designed similarly to the end caps according to the Fig. 16a and 16b Only the bearings and the stops or counter-stops for defining the outer and inner end positions are slightly different in terms of construction.
- a refill according to the invention or a storage unit according to the invention are based on a construction similar to that of the Fig. 16a and 16b an overridable inner counter stop 11b, which defines the inner end position I, as shown in the Fig. 20b shows.
- this counter stop 11b which consists for example of a small - possibly elastic - bump that can be driven over, can be driven over as a whole, it can fulfil two functions. On the one hand, it can determine the defined inner end position I ( Fig.
- the bearing pin 12 is on ( Fig. 17a, Fig. 17b ) or in the axle carrier (other figures mentioned) and preferably has a smaller diameter than the axle carrier. This allows the axle carrier to hold in the wound material web by clamping it radially on the outside, while the bearing pin 12 is axially movable radially further inward.
- axle carrier and the axially displaceable bearing pin 12 - viewed in the axial direction - are essentially located one behind the other, as is the case, for example, with the axle carriers to be described in more detail below.
- Figs. 25, 26 , 27 and 30 the case is.
- the bearing pin 12 advantageously has a - preferably - cylindrical neck 12c and a head 12b that is larger in diameter than the neck 12c.
- This design allows a mechanical test device, for example in the form of a curved mechanical track, as used by the Fig. 5 to 8 show, move the bearing journal in the axial direction and on the one hand pull it out of the refill, i.e. move it from the inner to the outer end position, but also apply it in the opposite direction.
- the pulling out is possible by gripping the head 12b in the area of the neck 12c.
- the front side of the bearing pin is formed by the cover surface of the head 12b, which runs essentially perpendicular to the longitudinal axis.
- the left bearing pin 13 and the right bearing pin 13 are axially displaceable relative to the axle carrier designed as a support rod 11.
- the left bearing pin 13 is acted upon by a spring 17 or generally by a force accumulator.
- rubber-elastic units Fig. 26
- magnets Fig. 27
- fluid-filled piston-cylinder units Fig. 28
- a variant of the invention provides a dispenser for sections of a refill with a material web wound into a roll, wherein the refill has at least one bearing pin which can be guided in a guide track of the dispenser from an insertion position to a dispensing position, wherein the refill is rotatably mounted in the dispensing position.
- This dispenser has a testing device for checking the axial displaceability of the bearing pin relative to the roll of the refill, wherein the dispensing of sections of the material web is dependent on the axial displaceability of the bearing pin.
- the test device according to the invention is used in the Fig. 1 to 12
- the check is essentially implemented mechanically in the dispensers shown by an axially offset (curved) section of the guide track.
- the test device attempts to move the bearing pin 12 axially and then, depending on the axial displacement, to release or block the output of the material web 15.
- This release or blocking or rendering inoperable can take place on the path of the material web (refill) inserted into the dispenser from above and wound into a roll downwards into the actual dispensing position, so that the check takes place before reaching the dispensing position, in which the roll then rotates to dispense the paper.
- it is also possible to carry out the check in the dispensing position as is the case, for example, with the Fig.
- a "normal" support rod 11 (axle carrier) is present, i.e. not designed according to the invention.
- This has a bearing pin 12, which is not axially displaceable relative to the support rod 11, but is fixed to it. It has a head 12b.
- the test device designated as a whole with 27, now tries to Fig. 21a or 21b when the material web 15 is pulled down and the roller 10 is rotated clockwise (21a) to constantly move the bearing pin axially.
- the test device comprises a friction roller 27a which is in contact with the material web 15 and is set in rotation by it when it is pulled off. This friction roller 27a has, as the Fig.
- 21c has a curved hump 28 on its front side.
- This curved hump meets the test lever 29, which as in Fig. 21b shown, is mounted so as to be displaceable in bearings 30 and is urged to the left by a spring 31.
- the hump 28 hits the test lever 29 during rotation, it pushes it to the right.
- the fork-shaped end 29a which grips around the bearing pin 12, then pulls it to the right by gripping behind the head 12b. If a "normal" support rod 11 or axle carrier is used, then when it is pulled to the right the left bearing pin 13 falls out of a holder in the dispensing position and the entire roll 10 or refill is then no longer correctly mounted and dispensing is prevented.
- the bearing pin 12 can oscillate during the pulling movement without the support rod 11 and the left bearing pin 13, which is integrally connected to it, falling out of their mounting.
- Such a refill or such a bearing unit with an axially movable right bearing journal then passes the axial test.
- the Fig. 22 shows a test device 27 for a roll 10 in the dispensing position with a material web 15 wound around a support rod 11.
- the right bearing pin 12 is designed to be axially displaceable.
- the test device comprises a test magnet 37, which works together with a test magnet 38 at the outer end of the axially displaceable bearing pin 12.
- the test magnet 37 attempts to position the bearing pin 12 in the Fig. 22 to the right. If this is possible due to its axial displacement, it enters the light barrier 39 and the electronic evaluation device releases the schematically shown lock 41 so that the material web can be dispensed. If the bearing pin 12 cannot be axially displaced, the light barrier 37 does not respond and the evaluation device 40 blocks the dispensing via the lock 41.
- the axial displacement can therefore be checked electromechanically in the dispensing position using the testing device 27.
- the Fig. 23 shows an embodiment of a refill or roll 10 according to the invention with an axle carrier in the form of a support rod 11, in which the right bearing pin 12 is axially displaceable, while the left bearing pin 13 is formed integrally with the support rod 11.
- an axle carrier in the form of a support rod 11, in which the right bearing pin 12 is axially displaceable, while the left bearing pin 13 is formed integrally with the support rod 11.
- the bearing pin 12 can then be pulled outwards, whereby in principle no defined outer end position has to be provided in order to realize the functionality of the invention.
- the bearing pin 12 is loosely inserted and can be completely separated from the support rod 11 if it is removed to the right in the direction of the two arrows.
- measures can be taken to ensure that the bearing pin 12 does not fall out of the support rod 11 during transport.
- the embodiment shown is a particularly preferred embodiment with an axle carrier or support rod 11 which has laterally projecting projections 24 which ensure good retention in a roll wound material web.
- the left bearing pin is formed in one piece with the support rod 11, while the right bearing pin 12 is axially displaceable according to the invention, specifically by the displacement path v, whereby stops and counter-stops (not shown in more detail here) define and fix the inner and outer end positions.
- the right bearing pin 12 is also rotatable in the rotation axis or roller axis 14 and has a groove 19 or generally a non-rotating surface on the front side. Rotary coding and axial coding can be achieved with such a bearing pin.
- the right bearing pin 12 is arranged in a line with the actual support rod 11 or axle carrier including the left bearing pin 13, i.e. one behind the other in the axial direction.
- a force accumulator in the form of a compression spring 17 acts between them.
- the inner end position, which in Fig. 25 is defined by the bearing pin 12 resting with its inner end on the right end of the support rod 11.
- An outer defined end position is present here similar to the embodiment according to Fig. 23 not.
- the energy storage device essentially consists of a rubber-elastic unit 32, which is Fig. 26 is completely compressed and thus defines the inner end position. Starting from this inner end position, the bearing pin 12 on the right can be moved outwards in the direction of the arrow, whereby the rubber-elastic unit 32 is stretched.
- the right bearing pin 12 is axially displaceable relative to the axle carrier or support rod 11 and partially functions as an axle carrier itself.
- the two parts 16a and 16b are arranged one behind the other in the axial direction. Magnets act in a repulsive direction between the two parts 16a, 16b and thus form a force accumulator that tries to push the two parts 16a and 16b apart.
- a piston-cylinder unit 34 acts as an energy accumulator between the two parts 16a and 16b, the cylinder being filled with a gaseous compressible fluid 35.
- a Seal is designated 36.
- the piston-cylinder unit 34 acts as a force accumulator, which presses the two parts 16a and 16b apart.
- Any test device only needs to exert a force axially inwards in one direction.
- the force accumulator which is implemented in a variety of ways (springs 17, rubber-elastic units 32, magnets 33 or piston-cylinder units 34), then acts in the other direction.
- the Fig. 29 shows a one-piece embodiment in which the spring 17 is formed integrally with the support rod 11 or the right bearing pin 12.
- the Fig. 30 shows schematically a simple embodiment of a bearing unit according to the invention with two parts 16a and 16b arranged one behind the other in the axial direction, whereby the left part 16a has projections 24 and serves as an axle carrier in a refill.
- the right part 16b is simultaneously an axle carrier and has a bearing pin 12 at its right end.
- the inner defined end position is achieved by the two parts 16a and 16b lying against each other.
- a small gap is shown between the two parts, which disappears when the inner end position is reached.
- Two parts 16a and 16b are also provided, one behind the other in the axial direction, but are additionally connected to each other in an axial tongue and groove connection for greater stability.
- the bearing pin 12 which is mounted axially displaceably in the support rod 11 or the axle carrier, does not have a separate head.
- the test device must then be designed differently than in the Fig. 1 to 11 For example, the test device can attempt to move the bearing pin 12 axially by means of frictional engagement. Depending on the test result, a suitable mechanical or electronic control can then be used to enable or disable the output in the sense of axial coding.
- Fig. 32 shows that the grippable head 12b is preferred, but in principle not necessary for the functionality.
- a rubber-elastic element is used to realize the axial displacement of the bearing pin 12, more precisely its head 12b.
- the head 12b is made of a relatively hard material and only the neck 12c is made of rubber-elastic material (including the T-shaped anchorage protruding on both sides in the support rod 11 and the head 12b).
- the head 12b itself is also made of rubber-elastic material.

Description
Die Erfindung betrifft eine Nachfüllung für einen Spender, insbesondere einen Sanitärspender zur Ausgabe von Toilettenpapier oder Handtuchpapier. Weiters betrifft die Erfindung eine Lagereinheit für eine solche Nachfüllung und schließlich auch einen Spender für Abschnitte einer Nachfüllung mit einer zu einer Rolle gewickelten Materialbahn.The invention relates to a refill for a dispenser, in particular a sanitary dispenser for dispensing toilet paper or paper towels. Furthermore, the invention relates to a storage unit for such a refill and finally also to a dispenser for sections of a refill with a material web wound into a roll.
In der Anmeldung werden folgende Begriffe im Wesentlichen wie folgt verwendet ohne darauf beschränkt zu sein:
Spender für zu Rollen gewickelte Materialbahnen (Nachfüllungen) sind in einer Vielzahl von Ausführungen bekannt. Bei den Materialbahnen handelt es sich vorwiegend um Papiere, insbesondere Sanitär- oder Hygienepapiere, Haushaltspapiere, etc. aber auch um Kunststoff- oder Metallfolien. Die Spender weisen häufig gegenüberliegende Wände auf, in denen Führungsbahnen von einer Einfüllstelle zumindest bis in eine Spendeposition, und gegebenenfalls weiter in eine Auffangkammer für leere, die Rollen aufnehmende Lagereinheiten vorgesehen sind.Dispensers for material webs wound into rolls (refills) are known in a wide variety of designs. The material webs are mainly paper, in particular sanitary or hygiene paper, household paper, etc., but also plastic or metal foils. The dispensers often have opposing walls in which guide tracks are provided from a filling point at least to a dispensing position, and if necessary further into a collecting chamber for empty storage units that hold the rolls.
Eine neue Nachfüllung wird also mit den beiden Lagerzapfen einer Lagereinheit in die beiden Führungsbahnen eingesetzt und rutscht dann im Allgemeinen unter Schwerkrafteinfluss nach unten in die Spendeposition. Wenn die Lagerzapfen an den Enden eines Tragstabs ausgebildet sind, so fällt der leere Tragstab nach Aufbrauch der Rolle weiter nach unten in die Auffangkammer und kann dort entnommen werden.A new refill is therefore inserted into the two guideways using the two bearing pins of a bearing unit and then generally slides downwards into the dispensing position under the influence of gravity. If the bearing pins are located at the ends of a support rod, the empty support rod falls further down into the collecting chamber after the roll has been used up and can be removed from there.
Wenn die Nachfüllungen immer gleich und lagerichtig eingesetzt werden sollen, beispielsweise damit die Materialbahn immer in der gleichen Position angeboten wird, so sind sowohl die beiden Führungsbahnen als auch die beiden Lagerzapfen verschieden ausgebildet, um das verkehrte Einsetzen zu verhindern.If the refills are always to be inserted in the same way and in the correct position, for example so that the material web is always offered in the same position, both the two guide tracks and the two bearing pins are designed differently to prevent incorrect insertion.
Die Übereinstimmung des gegengleichen Elementpaares aus Führungsbahn und Lagerzapfen wird Codierung genannt, und bekannte Codierungen umfassen beispielsweise den Durchmesser des Lagerzapfens und die Spaltenbreite der Führungsbahn, einen Lagerzapfen mit einer Lagerrille und in diese eingreifende Stege an der Führungsbahn, parallele Nichtrotationsflächen am Lagerzapfen und an der Führungsbahn, usw. Mittels unterschiedlicher Codierungen ist es insbesondere möglich, das Nachfüllen eines Spenders mit nicht geeigneten Rollen zu vermeiden, und die Verwendung von aufeinander abgestimmten Produkten sicherzustellen (
Eine Weiterentwicklung der oben geschilderten Codierung ist in der
Aufgabe der Erfindung ist es, eine weitere Codiermöglichkeit für einen Spender, eine Nachfüllung oder eine zugehörige Lagereinheit anzugeben.The object of the invention is to provide a further coding option for a dispenser, a refill or an associated storage unit.
Diese Aufgabe wird durch eine Nachfüllung mit den Merkmalen des Anspruchs 1 und/oder einem Spender mit den Merkmalen des Anspruchs 15 gelöst.This object is achieved by a refill having the features of
Die Essenz der Erfindung besteht darin, dass ein Lagerzapfen der Nachfüllung bzw. der Lagereinheit der Nachfüllung axial verschiebbar gelagert ist, womit eine Axialcodierung möglich ist: Nur Nachfüllungen bzw. Lagereinheiten für solche Nachfüllungen, die einen solchen axial verstellbaren Lagerzapfen aufweisen, funktionieren in einem geeignet ausgebildeten Spender ordnungsgemäß, während Nachfüllungen bzw. Lagereinheiten ohne solche axiale Verschiebbarkeit keine Ausgabe der Materialbahn ermöglichen. Diese Axialcodierung kann auch mit einer Drehcodierung gemäß der
Lagereinheiten für Nachfüllungen mit einem axial verstellbaren Lagerzapfen sind an sich bereits bekannt, beispielsweise aus der
Zudem ist aus
Die der Breite der Materialbahn entsprechende axiale Länge der Rolle entspricht von der Einsetzposition bis in die Spendeposition vorzugsweise dem Freiraum zwischen den Wänden des Spenders ohne nennenswertes axiales Spiel. Da die in Richtung der Rollenachse, also in Richtung der axialen Länge, versetzten Abschnitte der Führungsbahn bewirken, dass die aus der Rolle vorstehende Länge des von der Führungsbahn geführten Lagerzapfens sich verändern muss, wenn die nicht axial verschiebbare Rolle in die Spendeposition wandern soll, können nur Nachfüllungen verwendet werden, die einen axial verschiebbaren Lagerzapfen aufweisen.The axial length of the roll, which corresponds to the width of the material web, preferably corresponds to the free space between the walls of the dispenser from the insertion position to the dispensing position without any significant axial play. Since the sections of the guide track that are offset in the direction of the roll axis, i.e. in the direction of the axial length, mean that the length of the bearing pin guided by the guide track that protrudes from the roll must change if the non-axially movable roll is to move to the dispensing position, only refills that have an axially movable bearing pin can be used.
Somit erlauben der axiale Versatz in der Führungsbahn und die veränderbare Länge des vorstehenden Lagerzapfens, die dem Versatz folgen kann, eine neue Art der Codierung (Axialcodierung), und erhöhen gegebenenfalls auch bekannte Codierungsvarianten um eine weitere Ausführung.Thus, the axial offset in the guideway and the variable length of the protruding bearing journal, which can follow the offset, allow a new type of coding (axial coding), and may also increase known coding variants by another design.
Der axiale Versatz der Führungsbahn beinhaltet unterschiedliche Lösungen für die Lagereinheit, da die Länge der Lagereinheit sich vergrößert oder verkleinert, je nachdem ob der versetzte Abschnitt der Führungsbahn tiefer oder weniger tief in die Wand verläuft. Ein Tragstab ist bevorzugt zweiteilig, und die beiden Teile sind insbesondere teleskopisch ineinander verschiebbar. Ein Tragstab kann aber auch einteilig sein, wenn ein Bereich nach Art einer Ziehharmonika ausgebildet ist.The axial offset of the guideway involves different solutions for the bearing unit, since the length of the bearing unit increases or decreases depending on whether the offset section of the guideway runs deeper or less deeply into the wall. A support rod is preferably made of two parts, and the two parts can be moved telescopically into one another. However, a support rod can also be made of one part if one area is designed like an accordion.
In einer Ausführungsform ist vorgesehen, dass in beiden Führungsbahnen je ein in Richtung der Rollenachse versetzter Abschnitt ausgebildet ist. Hier müssen sich die Längen der Lagereinheiten vergrößern oder verkleinern, wobei in einer dritten Möglichkeit der Abstand der beiden Führungsbahnen zueinander gleich bleiben kann, wenn die beiden Abschnitte in die gleiche Richtung versetzt sind.In one embodiment, it is provided that a section is formed in each of the two guideways that is offset in the direction of the roller axis. Here, the lengths of the bearing units must increase or decrease, whereby in a third possibility the distance between the two guideways can remain the same if the two sections are offset in the same direction.
Sind die einander gegenüberliegenden Abschnitte der beiden Führungsbahnen in entgegengesetzter Richtung versetzt, so bedeutet dies bevorzugt eine Vergrößerung des Abstandes zwischen den beiden Führungsbahnen, sodass sich jede Lagereinheit, insbesondere durch Herausziehen vom Lagerzapfen, verlängern muss. Im umgekehrten Fall ist es auch denkbar, dass die Abschnitte zueinander versetzt sind, sodass sich beide Lagerzapfen verkürzen müssen. Diese Ausführung hat den Vorteil, dass die Führungsbahnen und die Lagerzapfen jeweils nur gegeneinander gedrückt werden, und keine Maßnahmen erforderlich sind, die das Herausziehen der Lagerzapfen ermöglichen, beispielsweise hinterschnittene Schlitze oder Nuten als Führungsbahnen und hintergreifbare Endabschnitte an den Lagerzapfen.If the opposing sections of the two guideways are offset in opposite directions, this preferably means an increase in the distance between the two guideways, so that each bearing unit has to be lengthened, in particular by pulling out the bearing journal. In the opposite case, it is also conceivable that the sections are offset from one another, so that both bearing journals have to be shortened. This design has the advantage that the guideways and the bearing journals are only pressed against one another, and no measures are required to enable the bearing journals to be pulled out, for example undercut slots or grooves as guideways and grippable end sections on the bearing journals.
Um das Einsetzen falscher Nachfüllungen zu vermeiden ist in einer bevorzugten Ausführung vorgesehen, dass der versetzte Abschnitt nahe der Einführposition vorgesehen ist. Dadurch wird bereits anfangs der Führungsbahn die axiale Verschiebung des Lagerzapfens erforderlich, und eine falsche Nachfüllung mit starrem Lagerzapfen kann wieder leicht entnommen werden.In order to avoid the insertion of incorrect refills, a preferred embodiment provides for the offset section to be provided near the insertion position. This means that the axial displacement of the bearing journal is required right at the beginning of the guideway, and an incorrect refill with a rigid bearing journal can be easily removed again.
In einer weiteren bevorzugten Ausführung ist vorgesehen, dass der versetzte Abschnitt nahe vor der Spendeposition vorgesehen ist. Diese Lösung erschwert zwar die Entnahme von falschen Nachfüllungen, schützt den Spender aber auch vor Beschädigungen durch Anwendung von Gewalt, um eine falsche Nachfüllung in die Spendeposition zu pressen, da diese von der Einführposition im Allgemeinen nicht direkt zugänglich ist.In a further preferred embodiment, the offset section is provided close to the dispensing position. This solution makes it more difficult to remove incorrect refills, but also protects the dispenser from damage caused by the use of force to press an incorrect refill into the dispensing position, since this is generally not directly accessible from the insertion position.
Im Anschluss an den Versatz der Führungsbahn kann diese wieder in die ursprüngliche Position zurückspringen, wobei ein herausgezogener Lagerzapfen wieder eingeschoben und ein eingeschobener Lagerzapfen wieder auf die ursprüngliche Länge herausgezogen wird. Es ist aber auch möglich, die Führungsbahn im Anschluss an den Versatz parallel zum Eingangsabschnitt in die Spendeposition weiterzuführen. Diese Ausführung ist vor allem dann vorteilhaft, wenn der Versatz den Abstand zwischen den Führungsbahnen vergrößert und unterhalb der Spendeposition eine Auffangkammer für leere Tragstäbe vorgesehen ist. In diesem Fall sieht ein bevorzugtes Ausführungsbeispiel der Erfindung vor, dass zwischen der Spendeposition und der Auffangkammer ein zweiter, axial versetzter Abschnitt vorgesehen ist, in dem der Abstand der beiden Führungsbahnen nochmals verändert, insbesondere zueinander weiter vergrößert ist. Eine zweite Vergrößerung führt dazu, dass die beiden Teile vollständig auseinandergezogen werden, und somit jeder Teil kleiner als der Tragstab ist. Die Entnahme der kleineren Teile wird dadurch erleichtert, ebenso die Entsorgung, insbesondere wenn für die Tragstäbe sich in Wasser zersetzendes Material eingesetzt wird.After the guideway has been offset, it can spring back into its original position, with a pulled-out bearing pin being pushed back in and a pushed-in bearing pin being pulled out to its original length. However, it is also possible to continue the guideway parallel to the input section into the dispensing position following the offset. This design is particularly advantageous if the offset increases the distance between the guideways and a collecting chamber for empty support rods is provided below the dispensing position. In this case, a preferred embodiment of the invention provides that a second, axially offset section is provided between the dispensing position and the collecting chamber, in which the distance between the two guideways is changed again, in particular further increased relative to one another. A second increase leads to the two parts being pulled completely apart, and thus each part is smaller than the support rod. This makes it easier to remove the smaller parts, as well as to dispose of them, especially if material that decomposes in water is used for the support rods.
Der zweite axial versetzte Abschnitt kann, bevorzugt unterhalb der Spendeposition, in derselben Führungsbahn wie der erste versetzte Abschnitt oder in der gegenüberliegenden Führungsbahn vorgesehen sein. Dort kann auch durch eine in der Führungsbahn ausgebildete Rampe oder dergleichen der Tragstab wieder verkürzt und aus beiden Führungsbahnen verdrängt werden.The second axially offset section can be provided, preferably below the dispensing position, in the same guideway as the first offset section or in the opposite guideway. There, the support rod can also be shortened again and displaced from both guideways by a ramp or the like formed in the guideway.
Weist jede Führungsbahn einen versetzten Abschnitt auf, so sind bevorzugt auch beide Lagerzapfen hintergreifbar ausgebildet. Als Lagerzapfen sind insbesondere solche geeignet, wie sie in der erwähnten
In der Länge veränderbare Tragstäbe, die eine Führungsbahn eines Spenders mit einem axial versetzten Abschnitt passieren können, können bevorzugt bereits in der Einführungsposition aus einer Transportstellung verlängert sein. In der Transportstellung entspricht der Tragstab im Wesentlichen der axialen Länge der Papierrolle, und weist damit ideale Voraussetzungen für die lagenweise Anordnung der Nachfüllungen mit Tragstäben in Verpackungskartons auf, da die Lagerzapfen in jede Rolle versenkt sind. Aus dieser Transportstellung werden die Lagerzapfen auf die für die Einsetzposition benötigte definierte innere Endlage herausgezogen und ihr axialer Überstand wird bei der Passage der versetzten Abschnitte wie oben beschrieben verändert.Support rods that can be changed in length and that can pass through a guideway of a dispenser with an axially offset section can preferably already be extended from a transport position in the insertion position. In the transport position, the support rod essentially corresponds to the axial length of the paper roll and thus has ideal conditions for the layered arrangement of the refills with support rods in packaging boxes, since the bearing pins are sunk into each roll. From this transport position, the bearing pins are pulled out to the defined inner end position required for the insertion position and their axial projection is changed as described above when passing through the offset sections.
Anstelle einer zweistufigen Verlängerung nacheinander in zwei zueinander versetzten Abschnitten der Führungsbahn kann eine Trennung der beiden Teile des Tragstabs auch bereits bei der Passage des ersten versetzten Abschnitts der Führungsbahn gleich im Anschluss an die Einführposition erfolgen, da die Rolle im Spender auch von den beiden nicht mehr ineinandergreifenden Teilen des Tragstabs ausreichend gestützt wird. Nach Aufbrauch des Papiers in der Spendeposition fallen daher bereits von dort die voneinander getrennten Teile nach unten.Instead of a two-stage extension in two sections of the guide track that are offset from one another, the two parts of the support rod can also be separated as soon as the first offset section of the guide track passes immediately after the insertion position, as the roll in the dispenser is also sufficiently supported by the two parts of the support rod that no longer engage with one another. After the paper has been used up in the dispensing position, the separated parts fall downwards from there.
Soll eine Wiederverwendung der Tragstäbe für neue Papierrollen verhindert werden, so kann eine weitere bevorzugte Ausführung vorsehen, dass die beiden Teile des Tragstabs nach ihrer Trennung voneinander nicht mehr oder nur mit großem Zeitaufwand zu einem Tragstab mit veränderbarer Länge der Lagerzapfen zusammengefügt werden können. Beispielsweise können sich spreizende oder ausbrechende Elemente, Laschen oder dergleichen von den den Lagerzapfen gegenüberliegenden Enden oder Rändern der beiden Teile ausgebildet sein, die das Ineinanderfügen und die teleskopische Verschiebbarkeit zumindest extrem erschweren.If the support rods are to be prevented from being reused for new paper rolls, a further preferred embodiment can provide that the two parts of the support rod can no longer be joined together to form a support rod with variable length bearing pins after they have been separated from one another, or can only do so with great expenditure of time. For example, spreading or breaking-off elements, tabs or the like can be formed from the ends or edges of the two parts opposite the bearing pins, which make joining together and telescopic displacement at least extremely difficult.
Wie bereits erwähnt, kann jede Führungsbahn als hinterschnittene oder nicht hinterschnittene Nut, bzw. hintergreifbarer oder nicht hintergreifbarer Schlitz in der die Rolle führenden Wand des Spenders, oder auch als vorspringender Steg ausgebildet sein, wobei beide Lagerzapfen die korrespondierenden Endbereiche aufweisen, die die axiale Aus- oder Einbewegung in den Führungsbahnen sicher stellen. Die Lagerzapfen können also Nuten in den Stirnseiten, Endflansche mit vergrößertem Durchmesser bzw. Endflansche bildende Umfangsnuten aufweisen.As already mentioned, each guide track can be designed as an undercut or non-undercut groove, or a slot that can be gripped behind or not behind in the wall of the dispenser that guides the roll, or as a protruding web, with both bearing pins having the corresponding end areas that ensure the axial outward or inward movement in the guide tracks. The bearing pins can therefore have grooves in the end faces, end flanges with an enlarged diameter or circumferential grooves that form end flanges.
Die Erfindung umfasst nicht nur eine Nachfüllung bzw. eine Lagereinheit mit mindestens einem axial verstellbaren Lagerzapfen sondern auch Spender, die dazu geeignet sind, solche Lagereinheiten bzw. Nachfüllungen aufzunehmen.The invention not only includes a refill or a storage unit with at least one axially adjustable bearing pin but also dispensers which are suitable for receiving such storage units or refills.
Bei einem Ausführungsbeispiel des Spenders ist eine Führungsbahn mit einer Übergangskurve vorgesehen, die den axialen Überstand des Lagerzapfens ändert. Diese Übergangskurve versucht also den Lagerzapfen axial zu bewegen. Wenn das gelingt, ist die Codierung in Ordnung und die Nachfüllung kann in die Spendeposition gelangen bzw. dort ein Abziehen der Materialbahn durch Drehen der Nachfüllung ermöglichen. Wenn die Lagereinheit bzw. die Nachfüllung so ausgebildet ist, dass kein axial verstellbarer Lagerzapfen vorhanden ist, erfolgt keine Ausgabe beispielsweise dadurch, dass der Tragstab in der Übergangskurve stecken bleibt.In one embodiment of the dispenser, a guide track with a transition curve is provided that changes the axial projection of the bearing pin. This transition curve therefore attempts to move the bearing pin axially. If this succeeds, the coding is OK and the refill can reach the dispensing position or enable the material web to be removed there by turning the refill. If the bearing unit or the refill is designed in such a way that there is no axially adjustable bearing pin, no dispensing takes place, for example if the support rod gets stuck in the transition curve.
Es ist ein Spendesystem mit einem Spender für Abschnitte einer Nachfüllung und mit mindestens einer Nachfüllung mit einer zu einer Rolle gewickelten Materialbahn vorgesehen, wobei die Nachfüllung zumindest einen Lagerzapfen aufweist, der in einer Führungsbahn des Spenders von einer Einführposition in eine Spendeposition führbar ist, wobei die Nachfüllung in der Spendeposition drehbar gelagert ist, wobei der Spender eine Prüfeinrichtung zur Überprüfung der axialen Verschiebbarkeit des Lagerzapfens gegenüber der Rolle der Nachfüllung aufweist, und wobei in Abhängigkeit von der axialen Verschiebbarkeit des Lagerzapfens die Ausgabe von Abschnitten der Materialbahn freigegeben oder gesperrt wird.A dispensing system is provided with a dispenser for sections of a refill and with at least one refill with a material web wound into a roll, wherein the refill has at least one bearing pin which can be guided in a guide track of the dispenser from an insertion position to a dispensing position, wherein the refill is rotatably mounted in the dispensing position, wherein the dispenser has a testing device for checking the axial displaceability of the bearing pin relative to the roll of the refill, and wherein the dispensing of sections of the material web is released or blocked depending on the axial displaceability of the bearing pin.
Mit einer solchen Prüfeinrichtung lässt sich die Axialcodierung überprüfen. Liegt eine axiale Verschiebbarkeit des Lagerzapfens gegenüber der Rolle der Nachfüllung vor, ist die Nachfüllung richtig codiert und eine Ausgabe ist möglich. Wenn umgekehrt eine solche axiale Verschiebbarkeit nicht oder nicht in der richtigen Weise vorhanden ist (nicht richtig codierte Nachfüllung), wird die Ausgabe der Materialbahn verhindert. Dafür gibt es verschiedenste Möglichkeiten: Beispielsweise kann eine nicht richtig codierte Nachfüllung auf dem Weg von einer Einführposition in eine Spendeposition vor Erreichen derselben aufgehalten werden. Es ist aber auch denkbar in der Spendeposition die Drehung der Nachfüllung, und damit der Ausgabe der Materialbahn zu verhindern, wenn keine richtige Axialcodierung vorliegt. Auch weitere Möglichkeiten zum Verhindern der Ausgabe der Materialbahn bei falscher Axialcodierung sind denkbar und möglich.The axial coding can be checked using such a test device. If the bearing pin can be moved axially relative to the refill roll, the refill is correctly coded and dispensing is possible. Conversely, if such axial movability is not present or not present correctly (incorrectly coded refill), the dispensing of the material web is prevented. There are various ways of doing this: for example, an incorrectly coded refill can be stopped on the way from an insertion position to a dispensing position before it reaches it. However, it is also conceivable to prevent the rotation of the refill in the dispensing position, and thus the dispensing of the material web, if the axial coding is not correct. Other ways of preventing the dispensing of the material web in the event of incorrect axial coding are also conceivable and possible.

Zu Rollen 10 gewickelte Materialbahnen 15 (Nachfüllungen), insbesondere von Haushalts- oder Sanitärpapier, benötigen im Allgemeinen, nachdem sie von einem Strang geschnitten worden sind, stirnseitig aus der Rolle 10 vorstehende Lagerzapfen 12, 13, um sie nach Öffnen eines Deckels 2 in Führungsbahnen 4 eines Spenders 1 (
Um das Befüllen des Spenders 1 mit falschen Rollen zu vermeiden, ist nahe der Einführposition 6 am Beginn zumindest einer Führungsbahn 4 eine durch einen axial versetzten Abschnitt 5 gebildete Sperre ausgebildet, die nur durch Änderung der Länge des Überstandes (also durch axiale Verschiebung) des in diese Führungsbahn eingreifenden Lagerzapfens 12 überwindbar ist. Kommt eine Nachfüllung mit einem falschen Tragstab (ohne axial verschiebbaren Lagerzapfen) zum Einsatz, so kann die Rolle den versetzten Abschnitt 5 nicht passieren, da die gewickelte Materialbahn zwischen den Wänden 3 nicht hin- und hergeschoben werden kann.In order to avoid filling the
Wenn eine Rolle 10 mit dem beidseitig vorstehenden Tragstab 11 in den Spender 1 eingesetzt werden soll, ist zuerst auf die richtige Ausrichtung zu achten, das heißt, der mit einem hintergreifbaren Endabschnitt 18 versehene Lagerzapfen 12 muss in die mit den versetzten Abschnitten 5 versehene Führungsbahn 4 eingesetzt werden. Die oberste Darstellung in
Nach der Einführposition 6 liegen die beiden zuerst nach rechts bzw. außen und dann wieder zurück versetzten Abschnitte 5 der Führungsbahn 4, die vom Tragstab 11 nur dadurch auf dem Weg in die Spendeposition 7 passiert werden können, wenn sie in der Lage sind, den Lagerzapfen 12 durch axiales Ausschieben zu verlängern und anschließend wieder zu verkürzen. Dies ist aufgrund der ineinander axial verschiebbaren Teile 16a und 16b des Tragstabs 11 möglich. Die versetzten Abschnitte 5 der Führungsbahn stellen somit ein Beispiel für eine Prüfeinrichtung dar, mit der sich die Axialcodierung von Nachfüllungen überprüfen lässt.After the
Dabei ist durch eine hier nicht näher beschriebene Maßnahme verhindert, dass der Teil 16a mitverschoben wird, und der Lagerzapfen aus der Führung gleitet.A measure not described in detail here prevents
Wie in dieser Ausführungsform gezeigt, setzt sich die Führungsbahn im Anschluss an die versetzten Abschnitte 5 wieder in der ursprünglichen Linie fort, und der weitere Weg in die Spendeposition 7 ist frei, sobald der Teil 16b und der Lagerzapfen 12 wieder in die Ausgangslage zurückgeschoben sind.As shown in this embodiment, the guide track continues again in the original line following the offset
Ein in der Rolle unverschiebbarer Tragstab mit einem nicht verlängerbaren bzw. axial nicht verstellbaren Lagerzapfen kann die versetzten Abschnitte 5 der Führungsbahn 4 nicht passieren, da die Rolle durch die Wände 3 des Spenders an einer axialen Verschiebung gehindert ist. Eine derart eingesetzte falsche Rolle kann nur wieder aus der Einführposition 6 entnommen werden.A support rod that cannot be moved in the roll and has a bearing pin that cannot be extended or axially adjusted cannot pass through the offset
Falls das für den Tragstab verwendete Material sich im Wasser zersetzt, können die beiden Teile auch in das Abwasser entsorgt werden, da die Länge der beiden Teile nunmehr so kurz ist, dass sie übliche Abwasserrohre passieren können.If the material used for the support rod decomposes in the water, the two parts can also be disposed of in the sewage system, since the length of the two parts is now so short that they can pass through normal sewage pipes.
Die
Alternative Konstruktionen können denselben Zweck erfüllen. Beispielhaft sei Folgendes erwähnt:
- 1. Der Abstand der Führungsbahnen 4 zueinander kann auch kleiner werden,
wenn der Abschnitt 5 nach innen in den Rollenaufnahmeraum versetzt ist. Die Lagereinheit wird dann bei der Passage des versetzten Abschnitts 5 insgesamt kürzer. - 2.
Beide Führungsbahnen 4 können in derselben Höhe in die gleiche Richtung versetzte Abschnitte 5 aufweisen, wobei die für diese Ausführung geeignete Lagereinheit ihre Länge nicht ändert, da der Abstand der Führungsbahnen 4 zueinander überall gleich ist. Es ändern sich aber die axialen Überstände der beiden Lagerzapfen 12, 13. - 3.
Der Tragstab 11 kann auch einteilig sein, wenn er einen beispielsweise nach Art einer Ziehharmonika ausgebildeten längenveränderlichen Bereich zwischen den beiden Lagerzapfen aufweist, und die damit die axiale Verschiebbarkeit mindestens eines Lagerzapfens realisiert wird (siehe auchFig. 29 ). - 4.
Der Tragstab 11 kann zwischen den beiden 16a,Teilen 16b eine Feder 17 aufweisen, die beispielsweise inFig. 10 oder auchFig. 25 gezeigt ist,wenn der Lagerzapfen 13 zylindrisch und nicht hintergreifbar ausgebildet ist.
- 1. The distance between the
guideways 4 can also be reduced if thesection 5 is offset inwards into the roller receiving space. The bearing unit then becomes shorter overall when the offsetsection 5 passes through. - 2. Both
guideways 4 can havesections 5 offset in the same direction at the same height, whereby the bearing unit suitable for this design does not change its length, since the distance between theguideways 4 is the same everywhere. However, the axial projections of the two bearing 12, 13 change.journals - 3. The
support rod 11 can also be one-piece if it has a length-adjustable area between the two bearing pins, for example in the form of an accordion, and thus the axial displacement of at least one bearing pin is realized (see alsoFig. 29 ). - 4. The
support rod 11 can have aspring 17 between the two 16a, 16b, which can be arranged, for example, inparts Fig.10 orFig. 25 is shown when the bearingpin 13 is cylindrical and cannot be gripped from behind.
Die Führungsbahn 4 weist in dieser Ausführung einen Querschnitt auf, der ausgehend von einer U-Form mit zwei an den freien Enden der Schenkel nach innen weisenden Stegen 21 und mit dem parallel zu den beiden Schenkeln mittig hochstehenden Steg 20 versehen ist. Vom Tragstab 11 ist jeweils nur ein Teil 16b der beiden axial verschiebbaren Teile 16a, 16b gezeigt. Die
Bei der Passage der beiden versetzten Abschnitte 5 wird der Teil 16b nach außen gezogen, während der Teil 16a an Ort und Stelle verbleibt, da er durch die Wicklung des Papiers daran gehindert wird. Die axiale Verlängerung des Lagerzapfens beim Passieren des ersten versetzten Abschnitts 5 ist in dem nur angedeuteten Tragstab ersichtlich. Der Buchstabe v bezeichnet die Größe des Versatzes nach außen, der bevorzugt größer als die Tiefe der gegenüberliegenden Führungsbahn 4 ist. Ein nicht passender, weil nicht verlängerbarer Tragstab würde in diesem Fall aus der zweiten Führungsbahn herausgezogen werden, wodurch der Spender blockiert (Axialcodierung), und eine Ausgabe der Materialbahn verhindert wird.When passing through the two offset

Die vorstehende Beschreibung von Ausführungsbeispielen der Erfindung lässt sich somit wie folgt zusammenfassen:
In einem Spender für Abschnitte einer zu einer Rolle gewickelten Materialbahn, insbesondere einem Papierspender, wird zwischen einander parallel gegenüber liegenden Wänden 3 eine Rolle 10 mit der gewickelten Materialbahn von einer Einführposition 6 in eine Spendeposition 7 axial geführt. Die Rolle 10 weist beidseitig axial vorstehende Lagerzapfen 12, 13 auf, und beiden Wänden 3 sind Führungsbahnen 4 für die Rolle 10 zugeordnet. An zumindest einer Seite des Spenders ist in der Führungsbahn 4 zumindest ein versetzter Abschnitt 5 ausgebildet, bei dessen Passage der axiale Überstand des Lagerzapfens 12, 13 während des Weges der zwischen den Wänden geführten Rolle 10 in die Spendeposition in Richtung der Rollenachse 14 geändert wird.The above description of embodiments of the invention can therefore be summarized as follows:

Wenn der Anschlag 12a am Gegenanschlag 11a anliegt, ist die definierte innere Endlage des Lagerzapfens 12 erreicht. In dieser Endlage steht er bzw. der Kopf 12b desselben, der mit einer radialen Nut 19 versehen ist, immer noch über die Rolle 10 vor und kann damit von einer hier nicht dargestellten Prüfeinrichtung im Spender leicht erfasst werden.The axially

Die Materialbahn kann zum Einsatz in einem Sanitärspender, vorteilhaft ein vorzugweise mit Abrissperforation versehenes Toilettenpapier sein.The material web can be used in a sanitary dispenser, preferably a toilet paper with a tear-off perforation.
Es ist aber auch möglich, dass die Materialbahn ein - vorzugsweise ohne Abrissperforationen - ausgebildetes Handtuchpapier ist.However, it is also possible that the material web is a towel paper - preferably without tear-off perforations.
Neben Materialbahnen aus Papier kommen aber auch andere Materialbahnen wie beispielsweise Frischhaltefolien oder andere Kunststofffolien in Betracht. Sogar Folien aus Metall, insbesondere Aluminiumfolien können zu einer Materialbahn gewickelt sein und bei der Erfindung zum Einsatz kommen.In addition to paper material webs, other material webs such as cling film or other plastic films can also be considered. Even metal films, particularly aluminum foil, can be wound into a material web and used in the invention.
