Definitions

  • the object of the invention is therefore to provide a towel apparatus which has the advantages of the electric drive and control, without being directly dependent on the mains voltage.
  • the invention solves this problem by means of a rechargeable electrical accumulator which is used in the towel apparatus.
  • the accumulator can be used to operate all or some of the functions of the towel dispenser without the need for a direct mains connection. However, it would be less favorable if it had to be charged directly in the towel dispenser or if it had to be removed from it separately and put back in again for this purpose. Therefore, in a preferred embodiment it is provided that the battery can be replaced together with a towel wrap. The towel must be replaced anyway when it is used up, so that the replacement of the battery connected to it does not require any additional work.
  • the accumulator can be designed as a commercially available dry accumulator. But there are also other rechargeable energy stores, e.g. appropriately designed capacitors etc. possible.
  • the accumulator can particularly preferably be arranged within a winding core of a towel roll.
  • the procedure for operating the towel dispenser is then preferably as follows: If a new towel wrap is used, it contains an accumulator in its changing room, which was charged in the service shop during washing and, if necessary, checked for its function. This clean wrap is inserted into a clean towel holder of the towel dispenser after the winding core of the previous clean towel winder has been removed from the clean towel holder and then inserted into a used towel holder, from which a used towel wrap is now in turn was removed. This is now returned for washing and charging the battery, so that there is an automatic cycle with recharging of the battery.
  • the winding core is given for cleaning and does not have to be removed from the used winding core, as has been the case up to now.
  • the clean towel is also delivered on a winding core and thus has better guidance.
  • the accumulator can preferably be arranged within a winding core of a towel roll, which preferably contains an inner core to be attached in the towel dispenser in a rotationally fixed manner and rotatably mounted thereon a winding tube for the towel roll.
  • contacting means for connecting the battery to the drive and / or control means of the towel dispenser and / or charging means on the winding core which are preferably designed to cooperate with a clean towel holder and / or a used towel holder. It can therefore be provided that only the battery contained in the clean towel wrap is electrically connected to the towel dispenser; however, it is also possible to provide this for clean and / or used towel wraps.
  • a towel roll drive with an electric motor and possibly a gear, which can drive the winding tube directly can preferably also be provided.
  • control connections would then have to be routed to the outside, which may also be provided without contact.
  • the control means for example control electronics, can also be provided in the winding core.
  • the procedure for washing the towel can be carried out in various ways.
  • the towel can be connected to a winding core via a leader that is not used as a towel and therefore cannot be washed, for example, from a film-like or coated fabric.
  • the winding core could then remain outside the actual washing process, while the leader also partially protrudes into the washing liquid.
  • the winding core can then be rewound immediately.
  • connection means can also be provided, with which the towels can be attached to one another on the one hand and to the winding core on the other hand, for example hooks, zipper-like connectors means, adhesive connectors, such as are known for example as Velcro closures, or the like.
  • the invention proposes that the roll towel be provided in a cassette-like, exchangeable exchange unit that can be inserted into and / or attached to the towel dispenser.
  • This unit or cassette can contain a clean towel and a used towel wrap and can preferably be surrounded by a cassette housing which has at least one inlet / outlet opening for a towel loop.
  • Such an exchange unit or cassette which is therefore preferably largely completed, but could also consist of an open frame with bearings for the individual windings, makes it possible to carry out the exchange with one hand and without particularly threading the towel.
  • Functional elements can already be installed in the cassette, for example guide rollers, but also the drive of the windings and the energy source for them, that is to say the accumulator and control means. It could therefore be a largely functional unit that practically only needs to be attached to a wall bracket with a quick connection in order to be ready for operation immediately. This unit would also have the advantage that it can be built very small and light.
  • the size is practically only determined by the roll width on the one hand and the winding diameter on the other, whereby due to the precise guidance of the towel roll, the dimension in the plane of both winding axes need not correspond to the sum of the two maximum angle diameters, since these can overlap if ensured is that the windings can run freely from one another in their half-unwound or wound-up position.
  • an accumulator serves as an energy store.
  • all electrical energy stores can be used as accumulators. Their design and their principle of operation depend on the practical circumstances and the amount of energy and energy density required.
  • a commercially available dry accumulator such as a NiCd accumulator, for example, can be used for larger continuous outputs.
  • An energy storage device in the manner of a capacitor could also be used for smaller and short-term outputs.
  • the end feed can be accomplished electrically, for example by a separate feed motor driving a pair of feed rollers that pull the end in.
  • the absence of a towel between a pair of contacts pressed resiliently against one another, which comes into contact after the towel dispenser has run through, can serve as a trigger signal, for example.
  • the pull-in motor can be driven by an accumulator installed in the device, which is charged by a generator via a control device, which is operated when the towel apparatus is operated manually. It can be the drive motor for the final feed, which acts as a generator in this situation.
  • the appropriate polarity and voltage regulation can be carried out via an electronic control unit.
  • This system is also not optimal from a hygienic point of view. Although the user always pulls out a clean section of towel at the front, there is usually a used towel on the back of the loop, so that it comes into contact with it almost automatically when it dries in the hanging area.
  • Changing the towel rolls can also be simplified with the usual direction of towel travel (front down) if the clean towel wrap is used over the used wrap. This can also be for other reasons, e.g. because of the simplified compliance with hygiene regulations.
  • FIG. 1 shows a towel dispenser 11 which has a base plate 12 fastened to a wall 14 and a hinged housing 13 which surrounds an interior 15 and has an inlet opening 16 and an outlet opening 17 for a towel 18.
  • the base plate 12 belongs to a support frame 19 with two side cheeks 20, between which two towel rolls 21 are mounted.
  • a used towel wrap 23 is provided under a clean towel wrap 22 and above.
  • the towel 18 is wound on winding cores 24 (FIG. 2). They have an inner core 25 which can be inserted into corresponding holders 27 on the towel dispenser via connecting elements 26. These receptacles 27 are attached to the side walls 20 of the base part 19 and have a shape adapted to the connection elements 26 provided on both sides of the inner core 25. They are designed in such a way that they hold the inner core rotatably, but removably, in the receptacles. Electrical contacting means 28 are provided in this and the connecting elements, i.e. interacting contact tracks.
  • connection elements 26 and receptacle 27 are provided on each receptacle and it is in any case advantageous to design the connection elements 26 and receptacle 27 differently on both sides of the winding core, so that the winding is used with certainty in a certain position. This is not only advantageous for the electrical connection, but also for determining the correct winding direction.
  • the different contacts can only be provided in the area of one connection element or on both. Combined with them or in addition, snap-locking elements can be provided which ensure that the winding core is clearly locked in place in its receptacles.
  • the inner core 25 contains the entire drive and the energy store for the winding drive.
  • an accumulator 29, control electronics 30, an electric motor 31 and an associated gear 32 are arranged axially one behind the other, which acts, for example via a pinion 33, on an internal toothing of a winding tube 34 which is rotatably supported on the inner core by means of bearings 35 .
  • Appropriate seals 36 allow the inner core to be shielded from the outside against all environmental influences, the functional parts in it being able to be influenced electrically only via the connecting elements 26.
  • connection means 37 are provided, for example hooks and eyes, cooperating adhesive elements, zipper-like connections or the like, in order to hold a towel end on the winding tube for winding.
  • the connection means provided on the towel should preferably be designed in such a way that they can be connected to one another as directly as possible or possibly also via a middle piece.
  • the winding sleeve and the end of the towel on the outside of the winding could have the softer part of a textile adhesive fastener which has textile loops, while the end of the towel inside the winding has the part of this adhesive or Velcro fastener provided with the corresponding hook structures.
  • Fig. 1 it can be seen that the clean-wrap 22 is arranged in the lower part of the towel dispenser 11 and the towel is guided downwards at its rear part closer to the wall 14, runs there via a guide 38, outside the housing 13 forms a loop 39 and runs through the opening 16 in the front housing part, in order to be wound up via a guide 40 on the used towel wrap 23 mounted in the upper part of the housing.
  • the used towel section 41 runs towards the wrap from the user side.
  • the loop is therefore always supplied with a clean towel section 43 on the rear side of the loop 39 remote from the user, while the use section 44 is on the user side, but shortly before the loop enters the opening 16.
  • the housing hood 13 can be pivoted in such a way that it exposes all outer towel parts, apart from a base section 45 which contains the outlet gap 17 and delimits the inlet gap 16 on one side.
  • an actuation button 46 On the front of the towel dispenser, an actuation button 46 is provided, which the user actuates before drying his hands. It triggers an actuation cycle, the sequence of which is controlled by the control means, in particular the switching electronics 30.
  • This switching electronics can, instead of in the winding core, also be attached to the towel dispenser or, for example, the electronics on the dispenser and the components that switch the motor current (mechanical or electronic relays) could be provided in the winding core.
  • a switch (not shown) can be triggered, which pulls any loop 39 by driving the used towel roll (or turning the clean towel roll back) until the towel, as indicated by the broken line in FIG. 1, is a flat-stretched section 48 abuts the bottom portion 45. The loop is therefore not visible and cannot be soiled.
  • This loop pull-in process can be ended, for example, by a switch 49 located in the area of the bottom section 45, which is actuated by the tensioned section 48.
  • the loop 39 is released. This can be done either by rotating the clean winding 22 in the actuating direction and / or by rotating the used winding 23 counter to the actuating direction 42.
  • a timer in the switching electronics 30 is started, which has a running time that is definitely longer than the usual drying process.
  • this time delay element starts the transport again and pulls the loop 39 in.
  • Either the clean section 43 can be drawn in by rotating the clean roll against the towel transport direction 42, so that the used section then lies as section 48 under the housing and can dry more easily there.
  • the usage section 44 would always be drawn in after use and be safe within the housing from being touched by other users, while the remaining, now smaller remainder of the loop is completed by dispensing a corresponding clean section 43 from the clean wrap to the full loop, after use (after the delay time has expired) or only when a new use cycle is initiated.
  • the accumulator 29 was charged during the towel washing in the service operation, after it was possibly completely discharged beforehand for regeneration. In addition, test procedures for the accumulator, the motor and the circuit could be carried out there, so that the functionality of the winding is always ensured.
  • the corresponding winding core 24 Since the corresponding winding core 24 is available after the Sauber winding has been used up, it can be used as a used winding core at the top when the towel dispenser is reloaded. With the integrated control as described above, the still functional accumulator can directly actuate the used winding, so that only control currents are to be conducted via the connections 26, while the entire high-voltage drive remains inside the winding. This considerably facilitates the contacting via the contacting means 28, which can optionally also be carried out without contact.
  • control means and thus the switching electronics are attached to the towel dispenser outside of the winding, then, in particular if the high-current switching relays are also provided outside, high-voltage connections are also led outwards from the winding.
  • the freshly charged accumulator 29 in the clean winding could also ensure the drive of the used winding 23, so that the accumulator in the used winding 23 no longer opened must be loaded to ensure the function.
  • the invention enables an ideal and hygienic control of the towel dispenser for the user with a minimum of external guides, without towel drive in roller gaps etc. and while avoiding greater mechanical effort. All functions can be carried out by direct winding actuation. Inserting and changing the wrap is particularly easy and can be carried out correctly even by inexperienced people without much thought. Above all, however, the function is ensured by the internal energy supply of each towel roll, regardless of the other mechanical design, even if the towel apparatus is not carried out, for example, via a winding core drive, but via other drive means, for example external rollers.
  • the towel dispenser can be made with smaller outer dimensions than previous ones. Since no mechanical control or drive parts have to run next to the winding, these determine the width. The depth is determined by the winding diameter and the height can even be chosen to be less than the sum of the two maximum winding diameters, because there are never two full wraps in the towel dispenser. It is therefore only necessary to ensure that the overall size determined by two half-wound packages is maintained.
  • the maximum winding diameters 50 (dash-dotted lines in FIG. 1) can therefore overlap.
  • a flexible separation such as a film 51, could be provided.
  • Fig. 3 shows a towel dispenser 11, which consists of a wall bracket 12a and a cassette 60, in which a clean towel wrap 22 and a used towel wrap 23 and all drive and control means and an accumulator 29 are provided.
  • the drive and control functions can be the same as previously described.
  • this cassette 60 is exchanged for another cassette which, in service mode, is put back into the ready-to-use state by washing the towel and charging the accumulator, etc.
  • Numerous cassette designs are possible between such a design, in which the cassette 60 contains all the functional parts of the towel dispenser and is only attached to a wall bracket by means of a quick-release fastener, and the replacement of the individual towel rolls.
  • a cassette can be used which only contains the towel rolls and the accumulator 29 and is connected to the drive electronics provided in the towel dispenser via contacting means provided on the cassette.
  • the towel wrap could be actuated via mechanical clutches, for example by means of gear wheels or claw clutches with automatic resilient latching elements.
  • Such a cassette can then be inserted into the towel apparatus and in some cases also contain housing sections of the towel dispenser. In any case, however, an easily replaceable unit is created which, with the appropriate training, is hygienically closed to the outside during storage and transport.
  • a towel dispenser base model can either be equipped or converted with an electrical or mechanical drive unit.
  • Fig. 4 shows schematically a towel dispenser with conventional drive by manually pulling the towel.
  • the loop 39 hanging out from the bottom of the device runs in the opposite direction to previous devices, i.e. the use section 44 of the towel is on the side of the towel dispenser facing the user, while the used towel runs back into the housing near the rear of the towel dispenser.
  • the clean towel wrap 22 is designed without a winding core, so that the wrap lies freely in a tub 55. From there, the towel runs between a ratchet wheel 56 and a pressure roller 57 and down to the loop 39 at the front of the device.
  • the used towel section 41 runs in at the rear of the device from below and passes a gap between two rollers 58. one of which is connected to an electric motor 59. This is electrically connected to a control device 66 and to an electric accumulator 29, which can be permanently installed in the towel dispenser.
  • the ratchet wheel 56 drives a winding roller 61 on which the used towel wrap 23 lies with its circumference. This is wound on an inactive winding core 62, which can run diagonally upwards in a guide 63, so that, by rotating the winding roller 61, the same amount of towels is wound up as is pulled from the clean towel roll 22 by pulling on the towel.
  • an electrical contact pair 64 is provided in the area of the clean towel, which is normally electrically separated by the towel passing therebetween.
  • the contacts come into contact with one another and a switching signal is generated which triggers a retraction of the end of the towel.
  • the control device also has a timer which keeps the motor 59 in operation only until it is ensured that the end is completely retracted.
  • the trigger signal of which is the consumption of the Sauber wolf, for example the lifting of the blockage of another towel dispenser that is loaded with a clean towel and was locked as long as the other was still in use , the transmission of the signal to a control center or the like.
  • the signal can be passed on by cable or wirelessly.
