Transfer device with surface disinfection and method for controlling a transfer device

description

A transfer device with surface disinfection and a method for controlling a transfer device are described.

background

Devices for the contactless transfer of different objects between two people are used in different versions in security technology. Such devices include Transfer facilities such as sliding troughs, material locks, etc. The devices for contactless handover primarily serve to ensure a safe handover of objects, with at least one of the people involved in the handover being protected.

The SARS-CoV-2 pandemic has greatly increased interest in contactless handover options. In addition to the contactless handover of objects, the disinfection of surfaces also plays a major role. Especially For the current situation, the disinfection of objects is therefore of great importance.

State of the art

Known disinfection measures include the spraying of liquid disinfectants that wet the surface of objects with a disinfectant. The germs and viruses present on the surface of the objects are then killed by the disinfectant.

However, this requires the use of suitable disinfectants. Such disinfectants can sometimes be hazardous to human health.

However, the disinfection of packaging material, documents of any kind and other objects that can be damaged or destroyed by moisture cannot be realized with conventional disinfectants.

DE 20 2007 015 765 Ul discloses a disinfection chamber for cleaning and/or disinfecting objects, with a chamber completely enclosing the object being provided, which has two opposite openings which can be closed by closure elements, with at least one ionization device for an ionization process to be carried out inside the chamber is provided. A sluice-like function of the disinfection chamber can be achieved by means of opposite input and removal openings with corresponding closure elements.

However, the disinfection chamber known from DE 20 2007 015 765 U1 has various disadvantages. For example, a seal is only achieved via the doors in order to prevent radiation from escaping from the disinfection chamber. It is also possible to open both doors at the same time, which means that there is no protection with regard to security aspects. In addition, the objects are placed in the space of the disinfection chamber by hand, so that in addition to the objects that may be contaminated, further contamination of the interior of the disinfection chamber and the inside of the doors by the inserted object or the user can occur, with both the The interior and the insides cannot be disinfected according to the object to be disinfected because they are covered by the object.

task

There is therefore the task of specifying a solution for the safe transfer and disinfection of objects, the disadvantages of the prior art being eliminated. In addition, the task is to specify a solution for the safe transfer of objects with simultaneous disinfection of the objects, which ensures rapid transfer and disinfection as well as safe transfer and disinfection, with no radiation escaping and the transfer taking into account safety-relevant aspects of transfer facilities.

solution

The above-mentioned object is achieved by a transfer device for the contactless transfer of objects and for disinfecting the objects, having at least one housing, one carriage, one drive train, two

flaps, at least one light source, and a controller, wherein the carriage can be displaced with the help of the drive train and can be partially moved out on opposite sides of the housing, the flaps for closing openings on the opposite sides being rotatably mounted and on the carriage from a closed position into a

Opening position can be moved, with only one flap being able to be brought into the opening position at a time, and the at least one light source is arranged in such a way that an object accommodated in the carriage can be irradiated, the at least one light source being designed to emit ultraviolet radiation .

The forced control of the flaps above the trolley on which the objects to be handed over and disinfected are placed ensures that the handover device can only be opened from one side. In this way, safety-relevant aspects are taken into account. The irradiation of the carriage and the object enables disinfection without the carriage and the object being damaged by disinfectant droplets or the like.

In further embodiments, the at least one light source can have at least one mercury vapor lamp emitting ultraviolet light, at least one light-emitting diode (LED) emitting ultraviolet light, at least one low-pressure lamp emitting ultraviolet light and/or at least one excimer radiation source.

Mercury vapor lamps require a burn-in time of up to several minutes to reach their maximum intensity and should not be switched on too often for reasons of service life, as this would destroy the lamp electrodes. For this reason it is necessary to operate the lamp continuously. To seal off the environment from the lamp To achieve this when one of the flaps is open, so that no UV light can escape, a shutter is provided for each light source in further versions described below. Such a shutter is used, for example, in versions of the mercury vapor lamps as amalgam -Lamps provided, including in particular no active cooling of the lamps must be done.

In further embodiments, the at least one light source can have at least one amalgam lamp emitting ultraviolet light, which has a high radiation flux and thus a relatively short irradiation time for disinfection.

In further versions, LED lamps can also be used. These can be switched as often as you like. However, these amalgam lamps, which emit UV light in particular, have an insufficient radiation flux and a shorter service life. The use of LEDs requires a disproportionately long irradiation time, which is not practical for a large number of designs.

Conventional low-pressure lamps emitting ultraviolet light have a lower intensity than amalgam lamps and therefore require a longer irradiation time to achieve the required lethal dose of the microorganisms. Therefore, they can only be used to a limited extent in the application of the transfer device.

For versions in which rapid and reliable disinfection is to take place, further preferred versions therefore use low-pressure mercury vapor lamps with amalgam doping that emit ultraviolet light used . These usually have to be actively cooled in order to achieve the optimal UV intensity.

In other versions, excimer radiation sources can be used as light sources emitting ultraviolet light. These emitters, also known as excimer lamps, are filled with an inert gas. Depending on the inert gas contained in a sealed quartz glass chamber, the desired ultraviolet wavelength is emitted. The entry of high-energy electrons into the lamp chamber results in an intensive plasma discharge, whereby the generated plasma contains high-energy electrons and can be extinguished immediately. The plasma induces atomic excitation of the inert gas in the lamp, triggering the formation of excited dimers.

Emission follows as the final phase of the reaction, with the return of the excimer triggering the emission of excimer-specific UV radiation. A disinfection-relevant radiation with a wavelength of 222 nm (KrCl) or 282 nm (XeBr) can preferably be achieved with a corresponding gas filling.

In further versions, the transfer device can have position detection means which are arranged in such a way that feedback can be given to the controller via the position detection means when the carriage is in a neutral position within the housing, in an extended position on a first of the two sides and is in an extended position on a second of the two sides. The position detection means can, for example. Include limit switches, which are arranged at appropriate points within the transfer device and provide feedback on the position of the car. In further embodiments, at least one light source can be arranged along the travel path of the carriage both above and below the carriage. This ensures that the entire interior space of the transfer device and the trolley as well as the object can be completely disinfected.

The at least one light source can be deactivated by the controller when the carriage moves out of its neutral position, in which disinfection takes place via the at least one light source. For this purpose, the position of the carriage can be detected using the position detection means and the light sources can thus be controlled.

In further versions, the transfer device can have at least one closure for covering the at least one light source when the carriage is in an extended position, with the closure releasing radiation via the at least one light source assigned to the closure when the carriage is in a neutral position within the housing. This ensures that the interior and the car can only be irradiated when the car is in the neutral position. If the carriage is moved out of the neutral position within the housing of the transfer device, the closure also moves, which then prevents the irradiation.

In the case of mercury vapor lamps and amalgam lamps in particular, such closures designed as “shutters” are provided in order to ensure constant operation of the light sources for disinfection while at the same time protecting against the emission of radiation. If the transfer device has, for example, at least one light source both above and below the carriage, the transfer device also has at least two closures, which reliably isolate the corresponding light source when the carriage is moved.

In further embodiments, the at least one closure can be mounted in the housing via a guide and coupled to the carriage. The coupling ensures that the breech is always moved together with the carriage.

In further embodiments, the at least one closure can be displaceable within the housing in accordance with the displacement of the carriage. It is essential that the closure is moved within the housing. If the carriage leaves the housing, there is no further displacement of the at least one closure. This ensures that the closure does not come out of the housing and is not exposed to additional contamination, even when the carriage assumes its partially extended end position. In addition, the closure can be of simple design, since there is no additional action on the closure, for example due to external forces on the closure when objects etc. are introduced. The limitation can take place, for example, via stops which prevent the corresponding closure from being guided out of the housing.

In further embodiments, corresponding magnets for coupling between the at least one closure and the carriage can be arranged on the at least one closure and on the carriage. This is a simple way to create a link ensures that e.g. also ensure isolation in the event of the failure of (sub)-units of the controller or the transfer device. This will e.g. ensures that even if the transfer device is opened by force via one of the flaps, no radiation escapes via the at least one light source into the interior of the transfer device in the area of the carriage if the carriage is moved manually out of the transfer device. In addition to the simple coupling between the lock and the carriage and the fail-safe coupling, little space is required for the coupling and no additional integration into the control system is required. In addition, there is no need for a separate drive for the at least one closure, as a result of which costs and installation space can be saved. The provision of magnets i . v. m . Stop elements for limiting the displacement path of the at least one closure offer the possibility of achieving decoupling in the event of further displacement of the carriage out of the housing. When the carriage is pushed back in, the two magnets on the clasp and on the body come into contact again and assume their predetermined opposite position. This simplifies the coupling and decoupling of carriages to closure elements.

In further versions, the drive train can have a drive unit which is coupled to the carriage for displacement in both directions. A single drive unit is therefore sufficient to move the carriage in both possible directions.

In further embodiments, the carriage can have at least one toothed rack which is in engagement with at least one first gear wheel, the at least one first gear wheel being coupled to the drive unit. The rotation of the first Gear according to the control via the drive unit then causes a displacement of the carriage in one of the two directions.

In further embodiments, the at least one first gear can be arranged in a section of the housing facing a first opening and at least one second gear can be arranged in a section of the housing facing a second opening, with the at least one first gear and the at least one second gear are coupled to the drive unit, the distance between the at least one first gear wheel and the at least one second gear wheel being so large that in the neutral position of the carriage, both the at least one first gear wheel and the at least one second gear wheel are in contact with the at least one toothed rack of the are in engagement with the car. Both gears can be coupled to each other via a chain or a belt, for example.

If control is via the drive unit, both gears move in the same direction, with either only the at least one first gear or the at least one second gear being in engagement with the rack of the carriage after the neutral position has been passed.

In further embodiments, at least one spring device can be provided for each of the flaps, which presses the associated flap into a closed position. This ensures that the flap remains in the closed position without any force being applied by the carriage. This eliminates the need for separate drives for the flaps and the controls can be kept simpler. In addition, it is ensured that the transfer device can remain reliably closed even if (sub)units of the transfer device or the controller fail. In further versions, the transfer device can have a guide along which the carriage can be displaced. The displacement path of the car is thus specified. In addition, the guide can be used to ensure that the carriage can only be displaced out of the transfer device in a specific manner and to a specific extent.

In further versions, the guide can have rollers on the housing and at least one runner which is arranged on one side of the carriage and is in contact with the rollers.

In other versions, the carriage can be designed to be at least partially transparent. E.g. the carriage can have a glass plate as a support for the object, so that the carriage and the interior of the transfer device can be disinfected through the glass plate. The glass plate can be, for example. be a plate of quartz glass. Furthermore, the use of thin-walled fluoropolymer films as carrier material is possible (PTFE, FEP, PFA, MFA, etc.). In general, the transparent design of the trolley or components thereof offers the advantage that disinfection is made possible through the transparent parts.

In further versions, the transfer device can have an operating device for controlling the carriage via the drive train.

In other versions, the operating device can have control panels or buttons that are used to move the carriage in and out and to stop the carriage. Control panels or buttons can, for example. stand for an output direction. In further versions, the operating device can have a contactless operating device, which carries out a corresponding displacement of the carriage by means of gestures by an operator. It is therefore not necessary to touch the transfer device or the operating device. This counteracts contamination of the operating device and prevents the transmission of pathogens, etc. via the operating device is prevented.

A contactless operating device can be designed in various ways. For example, a contactless operating device can be integrated directly in the housing of the transfer device or be connectable to the transfer device as a separate unit. Furthermore, a contactless operating device, for example have a light barrier and/or capacitively or inductively operating control panels (“control buttons”).

The above-mentioned object is also achieved by a method for controlling a transfer device according to one of the variants described above, having at least one housing, a carriage, a drive train, two flaps, at least one light source and a controller, with control commands being given to the controller via an operating device which, in accordance with the control commands, controls the drive train to move the carriage from a neutral position in the housing in a first direction and a second direction, the carriage moving at least partially out of the housing via the first opening or the second opening , The j eweilige flap is moved over the carriage when driving out and only then an irradiation of the carriage via the at least one light source Ultraviolet light occurs when the carriage is in the neutral position within the housing.

The method advantageously offers the possibility, as already stated for the transfer device, that the transfer device can only be opened on one side, in which case, when the flap is open, no radiation from the at least one light source enters the interior of the transfer device in which the carriage is the neutral position is stored, arrives. This ensures that no radiation can escape when the flap is open.

This can be achieved, for example, by the controller deactivating the at least one light source if it has been determined, for example via a position detection means, that the car is leaving the neutral position.

In other versions, the at least one light source can remain active when the car leaves the neutral position. This simplifies the control of the transfer device.

In further versions, the at least one light source can be covered by an associated closure when the carriage is moved out of the neutral position, with the closure being coupled to the movement of the carriage, and with the closure being able to be moved only within the housing. The coupling can take place in various ways, with a non-driven coupling preferably being provided. A non-driven coupling can be achieved, for example, using magnets. For this purpose, a magnet can be provided on the carriage and a corresponding magnet on the closure. When the carriage is moved, the breech is moved with it. About additional Slinging means can then limit the displacement of the at least one closure, so that it cannot be moved out of the housing of the transfer device, even if the carriage leaves the transfer device at least partially. There is thus a coupling between the at least one closure and the carriage which is dependent on the position of the carriage.

In other embodiments, the power supply to the at least one light source is interrupted, whereby the at least one light source is switched off when the car is in the neutral position and one of the two flaps is opened manually. For this purpose, a limit switch can be arranged on each of the flaps, which serves as a protective device against unauthorized opening.

In further versions, the operating device can have a light barrier, which has at least one light-emitting element and at least two elements receiving light from the light-emitting element, with the direction of the Movement of the car and its dwell time is controlled in the approachable positions. This can be used, for example, with a gesture using a finger or the hand of a user to carry out control without there having to be direct physical contact between the operating device and the user. The two light-receiving elements can lie one behind the other in the direction of movement, so that depending on which of the two light-receiving elements arranged one behind the other no longer receives light configured by the light-emitting element, the direction of movement can be detected using the gesture. Based on the detected direction of movement the gesture then causes the trolley to move in the corresponding direction via the controller.

In other versions, the dwell time of the carriage in the neutral position for disinfecting objects by irradiation with ultraviolet light via the at least one light source can be adjusted via the control in accordance with the output of the at least one light source and/or in accordance with the object to be disinfected. For this purpose, the controller can use a further device, such as an integrated scale, a camera or other, to record the size and/or the dimensions of the object and derive from this how long the irradiation with ultraviolet light is required. In further versions, an adaptation of a preset disinfection duration can be changed additionally or alternatively via the operating device. For this purpose, for example, the two light-receiving elements can be sealed off for a certain period of time, the period of isolation being representative of a disinfection period by ultraviolet light. For this purpose, time intervals can be defined which are representative of a disinfection duration. For example, a person's hand blocking a light barrier, with a corresponding time interval for activating the light sources being called up depending on the duration of the blockage. E.g. a 3-5 second isolation can trigger a 15 second disinfection period. A barrier of 6-10 seconds can result in a disinfection time of e.g. 30 seconds and a shading of 11-20 seconds a disinfection time of e.g. 1 minute etc. trigger . Several UV disinfection intervals can thus be stored, which are called up depending on the shading duration of the at least two light-receiving elements. Furthermore, the disinfection or Exposure time to UV light In accordance with the germs/viruses to be killed. For example, preset to kill a specific type of virus . Accordingly, the irradiation then takes place over a preset duration. However, an adjustment can be made via the operating device so that the irradiation time is adjusted, as stated above. Such an adaptation can also take place by means of an operator input via control panels/buttons instead of gesture control. In further versions, the adjustment can be made exclusively via the control panels/buttons. E.g. must be pressed simultaneously for a certain amount of time (see above) so that the irradiation duration (disinfection duration) is changed . The change can then be made for the next handover/disinfection of items. However, it is also possible for the change to be adopted for all future disinfection processes until a new input is made and/or the transfer device is disconnected from a power supply. In this case, after the transfer device has been connected to an energy source (eg mains power supply or accumulator), a preset irradiation time would be carried out by the controller, or the last irradiation time carried out would be used. For this purpose, the controller has a correspondingly designed memory.

In further versions, the transfer device also has an interface via which programming of the controller is possible. In this way, settings can be changed. It can also be possible that no or only a limited adjustment of settings can be made via the operating device. The at least one light source emits ultraviolet (UV) radiation, the UV light damaging the nucleic acids (DNA) of bacteria, viruses and other microorganisms when irradiated. The effect depends on the wavelength, the duration of irradiation and the distance from the radiation source to the irradiated surface.

Ultraviolet radiation is divided into three wavelength ranges:

UV-A: wavelength range 400-315 nm UV-B : wavelength range 315-280 nm UV-C : wavelength range 280-100 nm

The at least one light source preferably emits UV-C radiation, which is short-wave and very high-energy.

In further preferred embodiments, the at least one light source emits ultraviolet radiation with a wavelength of 222-285 nm, preferably approx. 254 nm, from which bacteria, viruses and other microorganisms are particularly badly damaged. The UV-C radiation causes irreparable destruction of the DNA, so that replication and thus no reproduction of pathogens can occur.

Further advantages, features and configuration options result from the following figure description of exemplary embodiments which are not to be understood as limiting.

In addition, there is no need to show and describe components that are not essential for understanding the technical teaching disclosed herein. In the following, the reference symbols are not repeated for all the elements that have already been introduced and shown, insofar as the elements themselves and their function have already been described or are known to a person skilled in the art.

From detailed description of exemplary embodiments

Various designs of transfer devices are shown in the figures, the transfer devices being designed as sliding troughs 100 in the designs shown. The designs specified for the sliding trays 100 can also be provided for other types of transfer devices.

The sliding troughs 100 described herein are used for the contactless transfer of objects with simultaneous disinfection of the transferred objects.

Such sliding trays 100 can be used in various facilities. E.g. Sliding troughs are already known which provide a transfer of objects when they are spatially separated. Such sliding troughs can be found, for example. at switches, where, for example. securities , identification documents , money etc . is handed over .

The sliding trays 100 described here have the advantage over the known prior art that the objects are disinfected when they are handed over. In addition it is ensured that the disinfection device of the sliding trough 100 does not endanger persons through escaping radiation. The troughs 100 are also designed so that a safe transfer is achieved in such a way that the troughs 100 can only ever be opened on one side, so that no direct contact between people on opposite sides of the trough 100 is possible.

For this purpose, the sliding troughs 100 shown have a carriage 200 which can move out of the sliding trough 100 in two directions. As a result, two people can hand over objects without coming into direct contact, with the two people being able to be spatially separated from one another.

Fig. 1 shows a perspective representation of a sliding tray 100 in a first embodiment. The sliding tray 100 has a housing 110 which essentially has a front and rear side 101 , opposite sides 102 and a bottom and a top 103 . On the top 103 there are three operating buttons 111 , 112 , 113 for controlling the carriage 200 , which is mounted within the housing 110 .

Flaps 120 are located on the front and rear 101 and are pivotably mounted on the housing 110 . Fig. 1 shows the closed state of the flaps 120 , with the carriage 200 being in a neutral position within the housing 110 for this purpose. Disinfection can also take place in this position (neutral position of the carriage 200).

A switch 105 , a plug contact 106 and a connector 107 are located on one side 102 of the housing 110 . On the Plug contact 106 supplies power to the sliding tray 100 . For this purpose, a suitably designed connection cable is plugged in, which can be connected to a power supply network via a socket. The sliding tray 100 is put into operation via the switch 105 . An operating device 900 (see, for example, FIGS. 2, 26, 27 and 28) can be connected via the connection 107 . An operating device 900 is used for contactless control of the sliding tray 100 instead of or in addition to control via the control buttons 111 , 112 , 113 .

The control knobs 111, 112, 113 are used to move the carriage 200 out of the sliding trough 100 in the respective assigned direction and to stop (control knob 112) the sliding trough within the housing 110 or to start the disinfection process in the neutral position of the carriage 200 . In the exemplary embodiment shown, control button 112 does not start the disinfection, but only moves the carriage 200 back into the neutral position. The service process is started when the carriage 200 moves e.g. is located on an inner side (corresponds to control button 111) and the control button 113 is pressed, with a transfer taking place and with the transferred object being disinfected during the transfer in the neutral position.

The sliding trough 100 can be inserted into a (transparent) wall, for example, in such a way that the operating buttons 111, 112, 113 are accessible to an operator for receiving or picking up objects. Accordingly, the operating buttons 111 , 112 , 113 are only ever used by the same person. On the part of a customer, an operating device 900 can be provided, which enables contactless control, so that no transmission of pathogens through direct contact via an operating device 900 can occur. In the embodiment shown, the sliding tray 100 is always operated by the operator. In this embodiment, a customer should only be able to place objects in the trolley 200 and remove them from the trolley 200 and not use the sliding tray 100 in the process. For this reason, in the exemplary embodiment shown, the operating buttons 111, 112, 113 and the operating device 900 are arranged on the “operator side”.

A lighting unit with LEDs is arranged in the oblong opening on the upper side 103 , which is used to indicate disinfection by flashing or lighting in any color. Radiation cannot escape via this opening, since the radiation-emitting components are isolated in boxes 142 and have only one opening for irradiation, which faces the interior of the sliding trough 100 in the direction of the carriage 200 in the neutral position.

The housing 110 can be made of a metal or a metal alloy or a suitable compound or made of plastic. A material mix of different materials for the components of the sliding tray 100 is also provided in further versions.

A display 710 of a display unit 700 is also accommodated on the upper side 103 . For example, the disinfection duration can be displayed in seconds via the display unit 710 . It is also possible to use appropriate light signals to indicate that disinfection by irradiation is taking place.

In further embodiments, displays 710 can also be provided at other locations on the housing 110 . For example, a display 710 can also be provided on a front side 101 and/or a rear side 101 .

Fig. 2 shows a perspective representation of a sliding tray 100 in a second embodiment. Other non-illustrated embodiments may differ from those shown in FIGS. 1 and 2 shown from guides, for example. distinguish in that e.g. no display unit 700 with a display 710 is provided on the top 103 , or that a switch 105 and a plug contact 106 are arranged on the rear 101 .

In the figs. 3-12 different views of the sliding tray 100 of the first embodiment and its components are shown. The essential components are discussed, with screws, nuts, washers and trim parts, etc. and components that are unimportant for understanding the technical teaching disclosed herein are not explained in detail.

Within the housing 110 the carriage 200 is slidably mounted via a guide of a guide system (FIGS. 21, 22, 25). The guide includes runners 240 and rollers 160, the rollers 160 being rotatably mounted on a plate 162, which plate 162 is connected to inner side walls (see Figures 17, 20). The parallel arrangement of the inner side walls to the outer sides 102 of the housing 110 is shown in FIG. 21 shown . The runners 240 are designed as strips and essentially extend over the entire side length of the carriage 200 . The runners 240 are arranged on side walls 210 of the carriage 200 via connecting elements 242 on both sides of the carriage 200 . The carriage 200 has a frame 230 on the sides of which the side walls 210 are arranged. The frame 230 holds a transparent glass panel 220 (FIG. 9). In the exemplary embodiment shown, the glass plate 220 consists of quartz glass. An elastic, frame-like holding layer is provided between the frame 230 and the glass plate 220 . The holding layers can, for example. consist of foam rubber.

The glass plate 220 serves as a support for an object that is to be handed over and disinfected. The transparent glass plate 220 ensures that the object is irradiated from both sides, both from above and from below, and thus complete disinfection can be achieved. The quartz glass plate allows UV light to pass through and ensures that recorded objects can also be irradiated from below.

In further versions, instead of a quartz glass pane, a thin-walled fluoropolymer film (e.g. PTFE, FEP, PFA, MFA) or another material that transmits UVC radiation can be used as the glass plate 220 for the carriage 200. If necessary, the radiation can be directed and intensified by reflectors.

In an advantageous embodiment, the interior of the receiving space can have a catalytic surface which can be irradiated in the entire UV range (UV-C, UV-B or UV-A). From this, a self-disinfection of the interior of the sliding tray 100 can be generated. A catalytic surface can be made of TiO2, for example.

Toothed racks 212 are arranged on the side walls 210 on the underside in the first embodiment of the sliding trough 100

(Fig. 18). Instead of a rack 212 in a In another embodiment, a sliding guide 214 can also be provided (FIG. 19).

The carriage 200 is moved via the toothed racks 212 . For this purpose, the racks 212 are in the neutral position of the carriage 200 with gears 432, 433 in engagement (FIG. 18). The gears 432 , 433 are driven by a motor 410 .

The sliding tray 100 has two opposed inner walls 140 inside the housing 110 disposed above and below the carriage 200 in the neutral position and extending between the inner side walls. The receiving and disinfecting space for the trolley 200 or defines the object.

The inner walls 140 thus separate this space from the remaining spaces within the housing 110 . For example, the control unit 300 and the drive 400 are located outside the receiving space.

In the neutral position, the carriage 200 is located essentially in the center within the accommodation space, with the distance to the flaps 120 being essentially the same on both sides (see FIG. 4).

Boxes 142 are located above and below the carriage 200 , in each of which a fluorescent tube 500 emitting ultraviolet light is arranged. These fluorescent tubes 500 extend in their longitudinal direction transverse to the displacement direction of the carriage 200 . Fans 600 are provided for cooling the fluorescent tubes 500 . Warm exhaust air is discharged via ventilation slits in the area of the underside of the housing 110 . The boxes 142 have corresponding walls which seal the space in which the fluorescent tubes 500 are accommodated from the remaining part of the sliding trough 100, so that no UV radiation can escape from the boxes 142. Part of the boxes 142 is formed by the inner walls 140 facing the receiving space. The boxes 142 in the inner walls 140 have an opening 144 extending parallel to the fluorescent tubes 500 . Ultraviolet radiation can reach the carriage 200 essentially centrally via the openings 144 both from above and from below.

The fluorescent tubes 500 emit ultraviolet radiation with a wavelength in the range of 100-280 nm. The so-called UV-C radiation is short-wave and very high-energy, so that bacteria, viruses and other microorganisms are particularly badly damaged. The UV-C radiation causes irreparable destruction of the DNA of the bacteria, viruses or microorganisms so that they can no longer reproduce.

With regard to the embodiments shown, the light sources emitting ultraviolet light are referred to as UV fluorescent tubes 500 . Fluorescent tubes 500 emitting ultraviolet light are understood here to mean, in particular, tubular, meandering or radial amalgam lamps and mercury lamps emitting ultraviolet light. In addition, other types of UV light-emitting light sources can also be used, which can be equated with the fluorescent tubes 500 . All of the statements relating to fluorescent tubes 500 therefore also apply to the other variants of light sources emitting UV light. E.g. mercury vapor lamps and low-pressure lamps as well as low-pressure mercury vapor radiation sources (with or without amalgam) and excimer radiation sources can be used. In other versions, excimer radiation sources can in particular emit ultraviolet radiation with a wavelength of 222 nm, which has a high disinfecting effect with little danger to people.

In the embodiments shown, the fluorescent tubes 500 are designed as amalgam lamps. The amalgam lamps are adapted and tuned to the operating conditions within the sliding trough 100 by technical measures.

For this purpose, the filling, the filling pressure, the electrodes and the operating conditions such as e.g. B. the advance current and the operating current and the preheating time in accordance with the disinfection to be carried out with regard to the objects to be disinfected and the germs, viruses and bacteria to be killed. Depending on the contamination of the objects and the contamination to be removed, the amalgam lamps can be adjusted or appropriate amalgam lamps are used or replaced.

Cooling devices with ribs or structures made of a thermally conductive metal can be arranged on the amalgam lamps, which provide particularly efficient heat dissipation ("heat sink"), possibly additionally with fans 600 (as shown, for example, in the figures), provide .

Individual adjustment measures as well as a combination of several measures may be necessary to ensure the correct and efficient operation of the light sources emitting ultraviolet light. Thus, at least one ballast, preferably electronically controlled, can be provided for the light sources emitting ultraviolet light, in particular the amalgam lamps, which ballast can additionally provide functional monitoring of the amalgam lamps. The function is monitored by means of the ballast or by upstream current or voltage monitoring, e.g. in the control unit 300 . Ballasts are used in gas discharge lamps to control the supply voltage and frequency in order to prevent damage to the lamps and to ensure that they can be operated at their optimum.

UV-C radiation in the range of a wavelength of approximately 265 nm is preferably emitted via the fluorescent tubes 500 .

Due to the formation of the inner walls 140 with the openings 144 in the boxes 142, UV radiation can thus enter the receiving space. To prevent radiation from escaping from the sliding trough 100 when one of the flaps 120 is open and the carriage 200 is extended, the sliding trough 100 has two closure plates 800 (“shutter”), each on the corresponding inner wall 140. For this purpose, a guide is provided on the housing 110. The closure plates 800 are guided by sliding guides, with both closure plates 800 being mounted via magnets 250, 810, preferably permanent magnets, which are mounted both on the closure plates 800 and on the carriage 200. to be moved .

The closure plates 800 have a V-shaped notch 820 for this purpose. The notch 820 is formed in a corresponding manner Guide groove mounted on the housing 110 (FIG. 21). The closure plates 800 can each be displaced in the displacement direction of the carriage 200 via the notches 820 and the guides.

The closure plates 800 each have an opening 802 . The openings 802 extend over substantially the same area as the openings 144 in the interior walls 140 when the carriage 200 is in the neutral position. This ensures that when the carriage 200 is in the neutral position, ultraviolet radiation can reach the carriage 200 and the object placed thereon through the openings 144 and 802 .

The closure plates 800 are used to prevent ultraviolet radiation from escaping from the boxes 142 when the carriage 200 is not in the neutral position. For this purpose, the carriage 200 has magnets 250 on each of the side walls 210 . There is in each case at least one magnet 250 in an upper area of the side wall 210 and at least one magnet 250 in a lower area of the side wall 210 (FIG. 22). When the carriage 200 is in the neutral position, these magnets 250 each lie opposite a magnet 810 which is aligned according to its polarity and which is arranged on the associated closure plate 800 via a magnet holder 812 . Thus, the shutter plates 800 are each displaced together with the carriage 200 when the carriage 200 is moved. The consequence of this is that the openings 144 and 802 are no longer congruently opposite one another, so that the openings 144 are increasingly closed by the closure plates 800 when the carriage 200 is displaced. The carriage 200 is located directly in the area of a flap 120, the closure plates 800 have already been shifted to the extent that the openings 144 completely from the Closure plates 800 are covered and an escape of ultraviolet radiation is no longer possible.

In order to prevent the closing plates 800 from being moved out of the housing 110 , stops 146 are provided on the inner walls 140 and limit the path of the closing plates 800 . The arrangement of the magnets 250 and 810 allows for a coupling between the closure plates 800 and the carriage 200 . The magnets 250 , 810 also make it possible for the coupling between the carriage 200 and the closure plates 800 to be maintained only as long as the carriage 200 is within the receiving space. When the carriage 200 leaves the receiving space, the magnets 250 are released from the magnets 810 because the closure plates 800 cannot move beyond the positions defined by the stops 146 . This also prevents the upper side of the carriage 800 from being covered over the closure plates 800 in the extended position, for example. In addition, the closure plates 800 can be protected from contamination or damage because they are only displaced within the accommodation space.

If the carriage is moved back into the receiving space, once the carriage 200 has reached a certain position, the magnets 250 and 810 will again be in an opposite position, so that the closure plates 800 will be moved together with the carriage 200 .

The coupling via magnets 250, 810 offers the advantage that a simple and secure coupling is provided, which also works independently if, for example, there is a fault in the control of the sliding trough 100 or the carriage 200 is forcibly moved out of the sliding trough 100. The carriage 200 is driven by the motor 410, which causes rotation of a drive shaft 430 and rotation of gears 432, 433 via gear assemblies and a chain 420, which mesh with the rack 212 of the carriage 200 in the neutral position. The motor 410, which is designed as an electric motor and is connected to the control unit 300 for this purpose, drives the gear wheel 432 directly via its gear wheel 412. Gear 432 is mounted on drive shaft 430 . A gear wheel 414 is also mounted on the drive shaft 430, which also drives the gear wheels 416 and 418 via the chain 420, so that the rotational movement of the gear wheel 432 is also transmitted to the gear wheel 433 (see Fig. 17, 18, 21, 22). .

The gears 432, 433 are connected to the carriage 200 via the rack 212. The gears 432, 433 are each on a separate shaft. In addition, the two gears 432, 433 mesh with the rack 212 only in the middle position (neutral position). As soon as the carriage 200 moves in the direction of one of the two end positions (FIGS. 24a), c)), only one of the gearwheels 432, 433 drives the carriage 200. This is engaged alone on the way to the end position and return to the middle position. In the central position, the respective other toothed wheel 433, 432 engages in the toothed rack 212 again and drives the carriage 200 in the opposite direction.

The two gears 432, 433, which cause the carriage 200 to move, are connected to one another via the chain 420 and the gears 414, 416, 418 (see FIG. 17). A synchronized rotational movement of the two gear wheels 432, 433 is ensured by the chain drive. The flaps 120 are pivotably mounted on the housing 110 . For this purpose, the flaps 120 are connected via a connection 123 to an arm 122 which acts as a lever. The arm 122 has a curved shape and allows the respective flap 120 to pivot in a corresponding direction. Due to its design, the arm 122 limits the maximum opening state of the flap 120 in the open position (see, for example, FIG. 14). In the open position, the formation of the arm 122 limits the further travel of the flap 120, since the arm 122 rests on an edge in the area of the opening on the front or rear 101 of the housing 110. In addition, a stop 128 limits the path of the arm 122 when pivoting.

The arm 122 is rotatably mounted on the housing 110 about the pivot point 124 . A torsion spring 130 is arranged in the area of the pivot point 124 . The torsion spring 130 is fixedly connected to the arm at a first end, this end of the torsion spring 130 being received in an opening 126 of the arm 122 . The second end of the torsion spring 130 is supported on a holding element 129 . The flap 120 is pressed into the closed position via the torsion spring 130 .

(see Figures 11 and 13).

If no internal force is applied to the door 120, the door 120 will remain in the closed position. The receiving space of the sliding trough 100 is therefore not accessible. In addition, circumferential seals can be provided both at the opening at the front and rear 101 of the housing 110 and at the flap 120 . The seals can also be used to ensure that no radiation escapes when the flaps 120 are in the closed position. The flaps 120 can be brought into their open position via the carriage 200 . For this purpose, the flaps 120 are pivoted against the force of the leg springs 130 because the carriage 200 presses against the flaps 120 from the inside. Since the flaps 120 are only pivoted via the carriage 200, it is not possible for both flaps 120 to be pivoted at the same time. If the carriage 200 moves back from an end position, the flaps 120 are pressed back into the closed position via the leg springs 130 .

The position of the carriage 200 is thus decisive for the position of the closing plates 800 and the position of the flaps 120 . Advantageously, this takes place without a separate control, so that the flaps 120 and the closure plates 800 are coupled to the movement of the carriage 200 independently of an energy supply.

the fig . 13, 14 show enlarged representations of sections C and D of FIG. 11, 12 in the area of the axis of rotation 124 and the arm 122.

the fig . 15-23 show further different views of the sliding tray of the first embodiment.

The position of the carriage 200 can be adjusted on both sides via an adjustment mechanism with a height adjustment 150 . Fig. 20 shows by way of example the configuration of the height adjustment 150 for the plates 162 so that the position of the carriage 200 can be adjusted accordingly. For this purpose, the plates 162 can be changed via screws in relation to the height in each case in two positions, so that a

Slope compensation is provided. Fig. 24 shows a schematic representation of different states of a sliding trough 100 . Fig. 24 b) shows the neutral position, with the carriage 200 being in the middle position and both flaps 120 being closed. In this position, the closure plates 800 are arranged in such a way that radiation from the fluorescent tubes 500 can reach the carriage 200 via the openings 802 and thus onto a carriage 200 or object placed on the glass plate 220 with the openings 802 and 144 being congruent with one another. Fig. 24 a) shows a state in which the carriage 200 has been extended on a first side and an object can then be loaded. The carriage 200 is then moved to the middle position (FIG. 24 b)), the covered fluorescent tubes 500 being released automatically and the corresponding flap 120 being closed in this position. In the neutral position, the above-mentioned disinfection can then be carried out using the UV radiation. Then, as shown in FIG. 24 c) shown, are moved out on the other side, the closure plates 800 also being displaced again and the associated flap 120 being pivoted automatically. The object placed on the trolley 200 can now be removed.

The carriage 200 is held in the receiving space of the sliding trough 100 via a guide system which is designed in such a way that it allows the carriage 200 to leave the housing 110 .

For this purpose, the carriage 200 is equipped with two runners 240 (one runner 240 per side), which slides on the rollers 160 and is guided by them. This allows the carriage 200 to perform a translational movement. Once the car 200 off moves in the housing 110 of the sliding trough 100 , it also partially leaves the rollers 160 .

In Fig. 25 are various states of the guide system and the carriage 200 of the sliding trough 100 of the first embodiment are shown schematically, with the runners 240 of the carriage 200 being guided in all positions from above over at least two rollers 160, so that the carriage 200 does not tilt can .

Fig. 26 shows a perspective representation of an operating device 900 for the sliding troughs 100 . The operating device 900 has a housing 920 which is shown in FIG. 27 surrounding components shown. The housing 920 consists, for example, of a plastic and is U-shaped.

A free space is provided between the two legs of the U-shaped housing 920, via which operating commands can be carried out by hand or via an object, such as, for example. a pen etc. , can be given .

Here, the direction of the movement through the free space between the legs is decisive.

Fig. 27 shows schematic representations of different versions of an operating device 900 for sliding trays 100 .

In Fig. 27 the operating devices 900 are shown without a housing 920 . Inside the housing 920 , the operating devices 900 have a plate 930 as a base, on which a connection socket 940 is arranged. Of the

Plate 930 extends laterally up two side walls 932 . An IR LED 942 is arranged on a first side wall 932 . Two IR receivers 944 spaced apart from one another are arranged on the opposite side wall 932 . Instead of a connection socket 940, a connection in the form of a micro USB connection can also be provided. E.g. can the connection be a USB 2 . 0 type B connection trade .

The IR LED 942 and the IR receivers 944 are connected to the connection socket 940 . The IR-LED 942 emits infrared (IR) radiation. The infrared radiation reaches the IR receivers 944 . These receive the radiation and provide feedback to the connection socket 940 in the form of a corresponding voltage, which is then transmitted to the control unit 300 of the sliding tray 100 via a line (e.g. cable 910) or by radio. The IR receivers 944 thus provide feedback as to whether there is an object between the IR LED 942 and the respective IR receiver 944 .

The control unit 300 of the sliding tray 100 controls the IR-LED 942 and receives the feedback from the IR receivers 944 . The feedback is converted into corresponding signals which are then transmitted via the connection to the control unit 300 of the sliding trough 100 . The control unit 300 then controls the drive 400 with the motor 410 on the basis of the information received via the signals. Furthermore, a display formed according to the signals received can take place via the LED unit on the upper side 103 . The travel speed and the holding time of the carriage 200 can also be set and displayed via this LED unit, which is designed as a strip.

About the display 710, the operating hours at the

Fluorescent tubes 500 or . of the UV lamps is displayed . So can be recognized early when a replacement is necessary .

The signals from the IR receivers 944 can be transmitted to the control unit 300 via the cable 910 . For this purpose, the cable 910 has a plug 912 (see FIG. 2 ), via which the operating device 900 can be connected to the connection 107 of the sliding tray 100 .

In a further alternative embodiment, an operating device 900 has an interface 950 via which contactless transmission of the signals can take place. For example, this can be an IR interface, a Bluetooth interface or another NFC (Near Field Communication) interface. For this purpose, the sliding trough 100 then has a corresponding interface for receiving and/or sending signals between the control unit 300 of the sliding trough 100 and the operating device 900 .

During operation of the sliding tray 100, the movement of the other movable components (closing plates 800, flaps 120) takes place via the activation of the carriage 200. The carriage 200 moves to three different positions

- End position A (see Fig. 7, 8, 24c) , 25c) ),

- Neutral or basic position (Fig. 18, 24b) , 25b) ),

- End position B (Fig. 23, 24a), 25b)).

The carriage 200 can move out of the sliding trough 100 in two directions. This allows two people to hand over

Carry out objects without coming into direct contact, whereby both people can be spatially separated from each other. The surface disinfection of an object is realized with the help of UV-C radiation. During the “disinfection phase” the carriage 200 is in the neutral or basic position at rest. The escape of UV radiation is prevented in this position of the carriage 200 by the two flaps 120 that close the housing 110 on the two end faces. The dwell time of the carriage 200 in the basic position can vary The decisive factors for the standing time are the required radiation dose on the one hand and the available power of the fluorescent tubes 500 on the other.

In further embodiments, instead of fluorescent tubes 500, other light sources emitting ultraviolet radiation can be provided (e.g. UV LEDs). For example, UV LEDs have a low power consumption and only develop a small amount of waste heat. It is thus possible to dispense with fans 600 in such designs.

Depending on the type of light source used, UV radiation is prevented from escaping from the housing 110 when the flap 120 is open, as shown for the first embodiment of a sliding trough 100, either by two closing plates 800 ("shutter") or by switching off the Light source is prevented in further embodiments that are not shown when the carriage 200 exits. The movement of the closure plates 800 ("shutter") can, as described above, be achieved via the magnetic force of opposing permanent magnets and by moving the carriage 200.

Sliding trays 100 can be operated by pressing operating buttons 111 , 112 , 113 and/or using a non-contact operating device 900 . The sliding tray 100 can be operated as follows:

In the basic position, the carriage 200 is in the middle position (middle position in the housing 110, both flaps 120 are closed). As soon as person 1 (hereinafter referred to as the customer) approaches the sliding tray 100 from position 1 (hereinafter referred to as the "customer side"), person 2 (hereinafter referred to as the operator) who is in position 2 (hereinafter referred to as the "operator side") opens the Sliding tray 100 in the direction of "customer side". The customer places object A in the carriage 200. The operator moves the carriage 200 into the end position "operator side". On the way to the end position on the "operator's side", the carriage remains in the basic position. Here the carriage 200 remains for a defined time t before the carriage 200 moves further into the end position "operator's side". There object A is removed by the operator and object B can be placed in the trolley 200 by the operator. Now the transfer process begins again. First, the carriage 200 moves to the home position and stays there again for the defined time t. The carriage 200 then moves on to the end position “customer side”.

Since the fluorescent tubes 500 lose power and thus the radiation dose over a defined period of time, the control unit 300 can automatically adjust the time the trolley 200 is in the holding position according to the required radiation dose and the power of the light source. For this purpose, a feature is integrated in the controller of the control unit 300 that makes it possible to design the handover process dynamically. D. H . that the dwell time of the car 200 automatically adapts to the life of the UV lamps or the fluorescent tubes 500 adapts . This will make the Handover process for new UV lamps or Fluorescent tubes 500 can be dealt with very quickly, whereas older UV lamps or Fluorescent tubes 500 the waiting time is increased. Such a feature is e.g. programmed into the controller.

In addition to the conventional operating knobs 111 , 112 , 113 or buttons, the sliding trough 100 can also be operated contactlessly via an operating device 900 . The operating device uses infrared sensors to determine the movement and recognizes the direction in which the carriage 200 is to be moved, so that the sliding trough 100 is moved accordingly.

A transfer device designed as a sliding trough 100 can be operated both via operating buttons 111, 112, 113 or buttons as well as a contactless operating device 900 can be controlled.

In the exemplary embodiment shown, the operating button 111 stands for the “inside” position of the carriage 200 , the operating button 112 for the “middle” position of the carriage 200 and the operating button 113 for the “outside” position of the carriage 200 .

The operation via the control buttons 111, 112, 113 takes place as follows:

For the standard function with cleaning (holding time in the

Middle position) of inserted objects in the

Central position (neutral position) of the carriage 200 in the sliding trough 100 there are various possibilities.

So when you press the control button 113, a normal

Ride with UV cleaning of the inserted item in the Center position are performed, with the carriage 200 in an extended position (e.g. "customer side"). If the middle position is reached while driving, then the carriage 200 is stopped for the set/defined time and then automatically continues towards the outer position until the outer position is finally reached.

While the carriage 200 waits in the middle position for the set time, a kind of flashing animation can be displayed via the LED unit on the top 103, which has a light-emitting diode strip, for example. This indicates that during this time the objects in the sliding trough 100 (e.g. box with medicines) are being cleaned/disinfected using the UV-C light.

The actuation of the control knob 111 causes the carriage 200 to move as for the control knob 113, but in the other direction.

Actuation of control button 112 attempts to drive carriage 200 to the center position. Once the center position is reached, the carriage 200 is stopped. Since this represents a rest position, there is no visualization of cleaning via the LED unit on the top 103.

If, for example, the position of the carriage 200 cannot be recognized when the sliding trough 100 is switched on (none of the internal position limit switches 352 are actuated), then the control knob 112 may not function. A defined position must then be approached either via the control button 111 or the control button 113 . In other versions, a function without cleaning can also be used in the middle position, i .e . H . direct passage of the carriage 200 from the inside to the outside position and vice versa, d. H . from the "operator side" to the "customer side" and vice versa. To travel from the inside position to the outside position without stopping in the middle position, the operating button 113 can be actuated twice (comparable to double-clicking with a mouse operation on the PC).

To travel from the outer position to the inner position without stopping in the middle position, the operating button 111 can also be actuated twice (comparable to double-clicking with a mouse operation on the PC).

The operation of the sliding trough 100 and the control of the carriage 200 can also take place via contactless input of the target position using the operating devices 900 .

The operating devices 900 are a type of forked light barrier, with which direction detection is also possible. In the exemplary embodiments of the operating devices 900 shown, the side walls 932 are approximately 50 mm apart and are approximately 40 mm high.

Fig. 28 shows the process for the contactless control of the sliding trough 100 via an operating device 900.

In order to make an input via an operating device 900, one moves a finger or a pen through the side walls 932 in the desired direction of travel. To e.g. To drive the carriage 200 from the inside position to the outside position, one slides a finger or a stylus through the side walls 932 toward the target position . The ride from the outside position to the inside position is done by moving your finger or other object through in reverse.

The control of the carriage 200 without cleaning in the middle position, with the carriage 200 being driven through directly from the inside to the outside position of the sliding trough 100, can be done by moving a finger through an operating device 900 in the direction of the outside twice. In order to drive through the carriage 200 from the outer to the inner position of the sliding trough 100, a finger can correspondingly be moved twice through the operating device 900 in the direction of the inner side.

To move the carriage 200 into the middle position, the finger can be moved by the operating device 900 first from the inside to the outside and then from the outside to the inside (or vice versa).

As already explained above, control buttons 111 , 112 , 113 and control devices 900 can be used in parallel in the input/control systems. The control buttons 111 , 112 , 113 can serve as the standard system. The IR input system (operating device 900) can also be easily connected via a cable 910 with a plug 912.
