Description

Double dispenser for disposable paper

Description:

The invention relates to a double dispenser for the mutual issue of disposable paper.

For events with a lot of public, e.g. at football matches, the visit of the sanitary facilities focuses on the event breaks. During these breaks, as many visitors as possible should be able to use the sanitary facilities without having to stand in front of empty or non-functioning toilet paper or towel dispensers. During these breaks, replenishment or maintenance is not possible due to public traffic in the sanitary facilities.

Double dispensers are known from the "Planning Information 2005, Dispenser Systems for Washroom Hygiene", HTS Deutschland GmbH & Co. KG, Business Unit CWS, page 6. Here, two mutually functioning towel dispensers are arranged side by side. If two persons standing next to each other want to dry their hands, only one of them will receive a piece of handkerchief. The other one has to wait until the first one has left the donor. The diameter of the towel rolls determines the depth of the dispenser and thus the required space. The donor is therefore often replenish, resulting in low availability. When refilling falls as waste, the plastic or cardboard support shaft of the used roll. The present invention is therefore based on the problem to develop a double dispenser with high availability, which is easy and safe to use.

This problem is solved with the features of the main claim. For this purpose, it comprises two dispenser units, which are arranged without lateral offset from one another and with at least approximately the same dispensing direction. Each dispenser unit comprises a stacking magazine for receiving a folded paper tape, a feed unit for transporting the paper tape from the stacking magazine for further processing, a separating device for separating disposable paper towels from the paper tape and an output unit for dispensing the thus separated disposable paper towels from the dispenser on. In addition, the distance between the two output units to each other is less than 300 millimeters.

Further details of the invention will become apparent from the dependent claims and the following description of a schematically illustrated embodiment.

Figure 1: towel dispenser in a laundry room; Figure 2: section through a towel dispenser; Figure 3: Detail of the towel dispenser. 1 shows the side view of a double dispenser (10) for disposable paper, which is arranged as a towel dispenser (10), for example, on the wall (2) of a laundry room in a football stadium.

The towel dispenser (10) has, for example, a height of 1100 millimeters, a depth normal to the wall (2) of 265 millimeters and a width of 320 millimeters. On its front side (11) pointing into the washroom, it has two dispensing slots (31, 131) for dispensing disposable paper towels (75, 175). These discharge slots (31) have at least approximately the same discharge direction (32, 132). The distance of the output slots (31, 131) to each other, for example, 60 millimeters, but it can be up to 300 millimeters. The paper towels (75, 175) have e.g. a

Width of 200 millimeters and a length of 300 millimeters.

The disposable paper dispenser (10) may also be a toilet paper dispenser. The width of the disposable paper towels is then e.g. 95 mm, the length 250 mm. The use for other disposable paper towels is conceivable.

The towel dispenser (10) shown in Figure 1, for example, arranged so that the imaginary center plane between see the dispensing slots (31, 131) is 1300 millimeters above the bottom (3) of the washroom. The distance of the underside (12) of the dispenser (10) to the bottom (3) in this embodiment is about 750 millimeters. Below the dispenser (10) is a waste paper basket (5), here e.g. has a height of 600 millimeters. The wastepaper basket (5) can be integrated in the double dispenser (10).

Above the upper dispensing slot (31) and below the lower dispensing slot (131), the dispenser (10) respectively a big door (13, 14). These doors (13, 14) each have a height of 500 millimeters. They can be pivoted so far that at least the stack magazine (41, 141), cf. Figure 2, can be filled. The opening width of the doors (13, 14) is thus for example at least 250 millimeters. The hinges (16) of the doors (13, 14) may be concealed.

Between the door (13) and the dispensing slot (31) and between the door (14) and the dispensing slot (131) is a non-contact switch (83, 183), e.g. an infrared switch arranged. Optionally, one of the switches (83, 183) can be dispensed with. In the illustration of FIG. 1, an operator (1) operates the upper non-contact switch (83). Actuation of this switch (83) causes the double dispenser (10) to dispense, for example, a disposable paper towel (75) from the upper dispensing slot (31).

On the side of the dispenser (10) there are two battery box ends (17). These each limit a battery compartment in which, for example, standard accumulators (18), cf. Figure 2 or - batteries are arranged. The battery compartments are e.g. accessible from both sides of the dispenser (10). Instead of two battery box lids (17), the dispenser (10) may also have a single battery box lid (17), which is then e.g. two battery compartments limited. If the dispenser (10) is connected to a mains supply, it can also be designed without battery compartments.

FIG. 2 shows a section through the double dispenser (10). The dispenser (10) here has a housing (15) in which two dispenser units (30, 130) are arranged one above the other. The housing (15) has between the two dispenser units (30, 130), for example, a transverse reinforcement (19). The housing (15) may also include two sub-housings, each sub-housing receiving a dispenser unit (30, 130).

Each of the two dispenser units (30, 130) comprises in this embodiment a stacking magazine (41, 141), a feed unit (51, 151), a separating device (71, 171) and an output unit (81, 181).

The two stacking magazines (41, 141) are cuboid cavities. On the trays (44, 144) there is respectively a reservoir (45, 145), e.g. on a stop (46, 146) is applied. The height of the reservoir (45, 145) is e.g. 450 millimeters. In each of them lies a folded paper web (42, 142) with a length of, for example, 300 meters. The single folder (43, 143) of the paper webs (42, 142) in this embodiment has a length of 150 millimeters and a width of e.g. 200 millimeters.

The feed units (51, 151) here each consist of a Papieraufnähme (52, 152), a conveyor channel (58, 158) and a conveyor device (65, 165). FIG. 3 shows, for example, a section of the feed unit (51) of the upper dispenser unit (30) and the feed unit (151) of the lower dispenser unit (130).

The respective paper receivers (52, 152) are arranged above the storage containers (45, 145) so that they are easily accessible when the doors (13, 14) are open. They are, for example, 50 millimeters from the front (11) of the dispenser (10). The paper receptacles (52, 152) have a feed roller (53, 153), by means of which the paper tape (42, 142) applied to a contact surface (55, 155) is drawn into the respective feed channel (58, 158). The intake roller (53, 153) is in this case, for example, spring-loaded in the direction of a Guide (56, 156) on which the fed paper slides or rolls along. To insert the paper tape (42, 142) this is applied to the respective contact surface (55, 155) and pushed on the contact surface (55, 155) up until it is taken over by the feed roller (53, 153) and in the respective Delivery channel (58, 158) is promoted. Each of the two feed rollers (53, 153) is driven for example by means of an electric motor, not shown here.

The conveyor channels (58, 158) guide the paper bands (42, 142) from the paper receivers (52, 152) to the conveyors (65, 165). The delivery channels (58, 158) consist of straight channels (59) and deflection channels (62). These are narrow channels whose cross section is only slightly larger than the cross section of the paper webs (42, 142). The inner walls of the delivery channels (58, 158) are smooth. This prevents snagging or tilting of the paper webs (42, 142) guided in the conveying channels (58, 158).

In the upper dispenser unit (30), the conveyor channels (58) guide the paper band (42) from the paper receiver (52) to the rear wall (21) of the housing (15). Here, the paper tape (42) is deflected and guided by means of the conveying channel (61) in the region of the housing (15) below the stacking magazine (41). By means of a further deflection (62), the paper tape (42) is guided in the direction of the front side (11) of the housing (15) and reaches the conveying device (65) there. This conveyor device (65) consists for example of two rollers (66, 67), of which at least the lower (67) is displaceable normal to the paper web (42). As soon as the paper web (42) actuates the detector (68), eg a reflection light barrier (68), the lower roll (67) is pressed in the direction of the upper roll (66) and the conveying device (65) takes over the paper receiving means (52 ) conveyed paper web (42). For example at the same time, the pick roller (53) of the paper receiver (52) can be switched to a freewheeling mode. If necessary, the feed roller (53) runs with braking in order to obtain the pretension of the paper web (42) in the conveying channels (58).

In the lower dispenser unit (130), the delivery channels (158) are constructed similarly as described in connection with the upper dispenser unit (30). However, the conveying device (165) lies above the stacking magazine (141), so that a channel (61) along the rear wall (21) can be dispensed with.

The respectively active conveying device (65, 165) pushes the paper web (42, 142) further out, the paper web (42, 142) being pushed over the separating device (71, 171). In this case, the length of the ejected paper web (42, 142) is monitored, for example, by means of a rotary encoder integrated in the drive of the roller (66, 166), a position measuring system or a timer. If a pre-set value of this measuring system is reached, the drive of the conveyor device (65, 165) is switched off. The length of each to be conveyed paper tape (42, 142), for example, between 150 millimeters and 300 millimeters adjustable.

At the same time or after switching off the conveying device (65, 165), the separating device (71, 171) is actuated. This includes, for example, a knife (72, 172), for example a roller blade and a die (73, 173). The knife (72, 172) cuts through the paper web (42, 142). This cuts off a disposable paper towel (75, 175) from the paper web (42, 142). The disposable paper towel (75, 175) is now eg in the output unit (81, 181), where it is not out of the housing (15) turns out, cf. the upper dispenser unit (30) in FIG. 3.

The output units (81, 181) comprise, for example, two belt conveyors (84, 85, 184, 185) arranged one above the other, detectors (82, 182) and the contactless switches (83, 183). The belt conveyors (84, 184) have, for example, a drive roller (86, 186). The other belt conveyor (85, 185) is e.g. normal to the former belt conveyor (84, 184) adjustable.

For example, the disposable paper towel (75, 175) lies between the two belt conveyors (84, 85, 184, 185). Upon actuation of one of the non-contact switches (83, 183) by the operator (1), the adjustable belt conveyor (85, 185) is pressed against the driven belt conveyor (84, 184), the drive roller (86, 186) is turned on and the disposable Paper towel (75, 175) in the discharge direction (32, 132) from the output slot (31, 131) output.

For example, between each of the output units (81, 181) and the output slots (31, 131) is a detector (82, 182), e.g. a photocell is arranged. This detector gives, for example, the feed unit (51, 151) the release, the next area of the paper web (42, 142) in the output unit (81, 181) promote.

As soon as the operator (1) actuates one of the two switches (83, 183), for example, first the upper output unit (81) is switched on. If the detector (82) is not damped within a preset period of time, for example 0.5 seconds, either the stacking magazine (41, 141) is empty or the paper transport is blocked. It is not possible to dispense a disposable paper towel (75). By means of an electrical circuit is now switched from the upper (30) to the lower dispenser unit (130). The lower dispenser unit (130) now takes over the dispensing of the disposable paper towels (175). As soon as the lower stacking magazine (141) is empty or a malfunction of the lower dispenser unit (130) occurs, the system is switched to the now refilled upper dispenser unit (30). This ensures that only one disposable paper towel (75, 175) is dispensed from the dispenser (10). By means of this mutual output of the disposable paper towels (75, 175), for example, 600 meters of paper web, which corresponds to, for example, 2000 disposable paper towels of 300 millimeters in length, can be dispensed before refilling.

If the stacking magazine (41, 141) is empty or the feed unit (51, 151) is blocked, a radio signal, for example, is sent to a central monitoring station. The dispenser (10) can then be selectively refilled or repaired. In order to distinguish these two sources of error, a fill level indicator of the stack magazines (41, 141) can additionally be provided. This can be an optical display or an optical or mechanical level monitoring.

If the operator (1) is impatient and tears the disposable paper towel (75, 175) out of the dispenser (10), this will not result in jamming or failure of the dispenser unit (10).

The residual piece remaining in the dispenser (10) is further conveyed in the dispensing direction (32, 132). Should blocking still occur, this is e.g. detected by the detector (82, 182). The electronic circuit then causes switching to the other donor unit (130, 30).

In both dispenser units (30, 130), for example, power supplies, such as accumulators (18) are arranged. In the normal paint operation, they are changed regularly. In this exemplary embodiment, they are connected in such a way that when the output voltage drops below a threshold voltage value, it is switched to the respective other power supply. At the same time, for example, a radio signal is output to the central monitoring station and the empty accumulator is indexed for replacement.

The dispenser (10) and its functional units (30-186) may also be constructed differently than described. Thus, the output units (81, 181) and / or the separating devices (81, 181) can be integrated into the feed units (51, 151). The respective feed unit (51, 151) then pushes the paper web (42, 142) out of the housing (15) by an adjustable length. Then the disposable paper towel (75, 175) is cut off.

The paper webs (42, 142) are stored, for example, in a warehouse and driven with a trolley for filling the dispenser (10) in a large sanitary facility. Due to the cuboid shape of the folded paper webs (42, 142), the required storage and transport volume for the paper webs (42, 142) is low. The degree of filling of the bearing and the transport vehicle can thus be above 90%.

For filling the dispenser (10), for example, the upper door (13) is opened and a carton (45) with a paper web (42) placed inside. The free end is pulled out of the box and inserted into the paper holder (52). The entry of the paper web (42) now takes place automatically, for example, as soon as the paper web (42) rests against the paper plant (55). Optionally, the feeder can also be initiated manually, for example by pressing a pull-in button. Instead of inserting a carton, a new paper web (42, 142) can also be inserted under a paper web (42, 142) already seated in the staple magazine (41, 141) and glued to it, for example. Other solutions are also conceivable. For this purpose, the stack magazines (41, 141), for example, be formed by 10% higher, to allow early refilling. The stack magazines (41, 141) may also have a different height.

To maintain the dispenser (10), the mechanical

Parts (30-186), for example, be accessible after opening the doors (13, 14) or the side walls. The delivery channels (58, 158) can be opened, for example.

Thus, the double dispenser (10) is easy and safe to handle and ensures high availability.
