Description

Field of technology

The invention relates to a disposal station with a dirt inlet opening and a receiving chamber having a flow connection to it, in which a bag for receiving dirt is arranged, the receiving chamber being assigned a means for compressing the dirt in the bag.

State of the art

Disposal stations of the aforementioned type are known in the prior art in a large number of different embodiments.

In a particularly simple case, the disposal station is a waste container which, for example, can receive and compress plastic waste, residual waste, organic waste or the like. To compress and dispose of rubbish, it is brought through the dirt inlet opening into a bag located in the receiving chamber. The dirt inlet opening can adjoin the receiving chamber directly or be connected to it by means of a flow channel.

The publication shows, for example, a special embodiment of a disposal station WO 00/54644 A1 . This has a receiving space to which a vacuum cleaner can be connected in order to take over dirt collected in the vacuum cleaner. The bag and thus also the dirt in it are compressed, for example by shrinking the bag after it has been filled.

In addition, it is also known from the aforementioned publication to fill a receiving chamber directly with dirt without using a bag, the dirt being compressed by means of a stamp inside the receiving chamber and then disposed of in a compressed state.

The disadvantage here is that the bag used either has to have a compressing property itself, or that if the dirt is compressed without using a bag, compressed dirt masses are also formed, but these are associated with just as much hygiene risk as loose dust or dirt.

Summary of the invention

It is therefore the object of the invention to create a disposal station for garbage and / or dirt, by means of which a simple compression and disposal of the same is possible.

To achieve the above-mentioned object, it is proposed that the receiving chamber have a compression ram which can be displaced relative to the bag in such a way that the compression ram presses from the outside against at least a partial surface area of the bag in order to compress the bag and the dirt therein.

According to the invention, the disposal station is designed such that the compression ram does not come into direct contact with the dirt to be compressed, but acts from the outside against the bag in which the dirt is located. The dirt compressed in this way is then already hygienically packaged in the bag, which can then be further handled particularly easily and preferably without dirt escaping from the bag. In a particularly simple case, the user can remove the bag compressed in this way from the receiving chamber of the disposal station and dispose of it in a household waste container, container or the like. In this sense, the bag is then preferably a disposable bag, which is disposed of at the same time as the dirt. The pouch can be made of various materials. For example, the bag can be a plastic bag. Furthermore, it is also possible to manufacture the bag at least partially from a sustainable material, for example paper, cardboard, natural fibers or fabric or others.

According to a particular embodiment it can be provided that the disposal station is a base station for an electric vacuum cleaner, the disposal station having an interface having the dirt inlet opening for docking the electric vacuum cleaner. According to this embodiment, the disposal station serves to take over dirt from a dust collection chamber of a vacuum cleaner. The electric vacuum cleaner can be connected to the dirt inlet opening of the disposal station, for example with a suction mouth, which is used to suck in dust and dirt during normal suction operation of the vacuum cleaner, so that the suction material in the vacuum cleaner can be transferred into the bag of the disposal station. For this purpose it can be provided that the disposal station has a fan which is set up to apply a negative pressure to the dirt inlet opening. This allows dirt starting from the Dirt inlet opening are conveyed into the receiving chamber. Furthermore, it is possible that a pressure fan is used to convey the dirt from the vacuum cleaner into the disposal station, for example the vacuum cleaner's own fan, which, for example, is valve-controlled with its pressure side connected to the dirt inlet opening of the disposal station, or that the vacuum cleaner's fan is operated with the opposite direction of rotation. Alternatively, it is of course also possible in principle that the dirt from the vacuum cleaner is transferred to the disposal station without the assistance of a blower, for example by moving the dirt, following gravity, from a dust collection chamber of the vacuum cleaner into the receiving chamber of the disposal station or the bag arranged therein, falls. A fan with a cyclone separator is preferably assigned to a flow channel of the disposal station, so that the dirt entering the flow channel through the dirt inlet opening can be removed from the air flow and is finally separated into the bag. After completion of the filling process at the disposal station or as soon as a certain filling level of the bag and / or the receiving chamber is reached, the bag and thus also the dirt contained therein is compressed by means of the compression ram. The compression ram can be driven electromechanically, hydraulically, pneumatically or in some other way. To determine the filling level, the receiving chamber or the bag is assigned a sensor which can, for example, weigh the bag contained in the receiving chamber in order to determine the amount of dirt contained therein. Alternatively, it is also possible for the filling level of the bag to be measured optically. For this purpose it can be provided, for example, that the bag is made of a material which is transmissive for a light wavelength with which a corresponding detection device works. Furthermore, it is also possible for a user of the disposal station to manually trigger a displacement of the compression ram, for example by pressing a button, actuating a foot switch or the like. During a compression process, any dirt components that may escape from the bag, for example fine dust, can be sucked off by a blower of the disposal station, whereby these are preferably caught by a filter element, for example a motor protection filter.

The connection between the disposal station and the connected vacuum cleaner or dirt container is preferably airtight, so that the dirt can be transferred to the disposal station without a user present next to the disposal station being impaired.

It is also proposed that the disposal station have a closure device for closing the bag. After the bag has been filled with dirt, the closing device serves to close the bag as tightly as possible, so that dirt, fine dust, odors or the like can no longer escape from the bag. The bag can be closed, for example, by applying pressure or by introducing temperature. The bag is particularly preferably closed in an edge area of the bag, the edge area preferably being able to have a special material for this purpose. For example, it is possible for an adhesive to be applied to the edge area, which adhesive can close the opposite circumferential areas of the bag edge by applying pressure or applying temperature. According to one embodiment, the closure device can have a heating device. This heating device can activate the adhesive or alternatively also soften a material component of the bag so that the edge area can be welded. According to this embodiment, the bag can thus be closed by welding. For this purpose, the heating device can, for example, have activatable electrical welding contacts, as are known, for example, from what are known as film welding devices. The material of the bag is suitable for electric welding. It is sufficient if the relevant edge areas are suitable for electrical welding. The bag can also be made from other materials, in particular from sustainable materials. In a further embodiment, the bag can also be closed by gluing, as mentioned, for which purpose, for example, on the inside of the wall, i. H. an activatable adhesive is to be applied to the peripheral areas of the bag facing one another. In this context, for example, a heat-activatable adhesive can be provided. The opening of the bag can thus be closed under the action of pressure and, if necessary, heat. It is also possible to close the bag with a pressure, clamp or Velcro fastener.

In this context, it is proposed as advantageous that the closure device is arranged on a partial area of the compression ram facing the bag. According to this embodiment, the compression ram thus not only serves to compress the bag or the dirt contained in the bag, but at the same time also to close the bag. It is therefore not necessary to provide two separate devices for compressing and closing the bag. Rather, the compression ram compresses the bag on the one hand and closes it on the other hand as soon as a defined compression is achieved is reached. A partial area of the compression ram that has been moved against the bag can have heating elements, in particular electrical resistance heating elements. In this way the edge area of the bag can be heated and sealed. It is sufficient if only that part of the compression ram is heated that actually rests against the bag.

It is proposed that the disposal station have a storage device for storing a plurality of bags, and / or that the disposal station have a feed device for feeding a bag into the receiving chamber, the feed device preferably being designed for automatic feeding of the bag. The storage device comprises a memory in which a plurality of bags are stored. The bags can, for example, be wound up one behind the other on a roll and can be separated from one another at a separation point provided for this purpose, in particular a perforation. In a preferred embodiment, the bags can be separated by cutting, pulling, applying heat, tearing off or the like. Furthermore, the bags can also be stored in a magazine, for example in the form of a bag stack within the disposal station. In any case, the bags are stored in the storage device in such a way that when a filled bag is removed from the disposal station, a next, unfilled bag can move into the receiving chamber. The storage device is preferably connected directly to the receiving chamber, so that a next bag can be supplied in a particularly short way. The disposal station advantageously has a feed device which can remove and / or take over a bag from the storage device and transfer it into the receiving chamber. If the disposal station does not have a storage device for bags, the feed device is preferably set up to take over a bag that has been manually inserted into the disposal station by a user and to insert it into the receiving chamber in a defined manner. The feed device can preferably be assigned a means for opening the bag, for example a blower from the disposal station, to pressurize the fresh bag with air in such a way that it opens and preferably lies against the inner wall of the receiving chamber. The feed device can be controlled fully automatically in such a way that a new, unused bag is inserted into the receiving chamber after the bag has reached an optionally predetermined level of filling. In particular, the feed device can be designed to support the movement of a new bag that is already present in the disposal station before the filled bag is removed from the receiving chamber when a filled bag is removed from the receiving chamber.

The feed device preferably has at least one feed element which can be displaced relative to the receiving chamber for gripping and / or opening a partial area of the bag. For handling a fresh bag, the feed device preferably has at least one feed element that engages the bag. This feed element can be, for example, a gripper, hook, suction cup or the like that holds a partial edge area of the bag and removes it from an opposite partial edge area, so that a bag opening is opened and is finally exposed. An actuating element can be assigned to the feed element, for example a pull rope or the like that is in a mechanically operative connection. The feed device preferably has a guide for the feed element, so that the advancing movement for the bag and the opening movement of the bag take place in a defined manner. The guide can be, for example, a rail guide, link guide, groove guide or the like. The feed element can, for example, access a stack of bags or a roll of bags that is stored in the storage device of the disposal station. The feed element can then be moved along the guide device towards the bag, for example grasp a partial edge area there and pull it over a dirt inlet opening of the receiving chamber so that the bag can be opened into the receiving chamber, for example, by a blown air stream and / or also by the compression ram into the Receiving chamber is pressed, preferably so that the bag rests from the inside against an inner wall of the receiving chamber and its maximum volume is available for receiving dirt. The feed device can also have two or more feed elements which engage opposite peripheral areas of the bag edge and thus pull apart a bag opening. One of the supply elements should at least be designed to be displaceable, the other supply element either being fixed relative to the receiving chamber or being displaced from the other supply element and relative to the receiving chamber.

The storage device for storing the bags can be assigned to the receiving chamber at different positions. For example, the storage device can be placed relative to the receiving chamber in such a way that a next bag to be transferred into the receiving chamber is positioned in or on a region of the receiving chamber in which the compression ram enters the receiving chamber. This area preferably corresponds to the direction in which dirt enters the receiving chamber or the bag. Alternatively, the storage device can also be assigned to the facing partial area of the receiving chamber, namely for example in such a way that the The feed device grips the edge area of the next bag and then leads, for example, from the innermost partial area of the receiving chamber to the punch-side edge area of the receiving chamber.

After the bag has been filled with dirt, the compression of the bag takes place in a user-controlled or automatically controlled manner by means of the compression ram, whereby either the feed element that spans the bag is retracted beforehand and thus releases a displacement path for the compression ram in the receiving chamber, or the bag edge that has been held up until then is released, i.e. . H. lets go, so that the bag edge, preferably following the force of gravity, can sink down into the receiving chamber until it folds over or lies on other partial areas of the bag and the bag can then be closed by the closure device. Furthermore, it is also possible for the bag to be released from the feed device by means of the compression ram. In this embodiment, care must be taken that the compression ram is not inserted into the bag opening, but rather engages a portion of the bag from the outside so that the bag can be closed and compressed.

According to one embodiment, the storage device of the disposal station can have a sensor which is set up to detect a supply of bags in the storage device. The sensor is set up and designed to detect the filling level of the storage device with bags. The sensor can be, for example, an optical sensor or a weighing sensor. The sensor is preferably coupled to a control and evaluation device of the disposal station, which evaluates the detection signals of the sensor and recognizes an approaching or already existing emptying of the bag supply. The control and evaluation device can then, for example, initiate the output of a message on a display of the disposal station or the output of a preferably wireless signal to a terminal of the user that is external to the disposal station, so that the user is informed that the bag supply is already exhausted or tends to come to an end shortly and accordingly a new supply of bags is to be introduced into the storage facility of the disposal station.

Finally, it can be provided that the receiving chamber of the disposal station has a displaceable chamber closure element which can be opened for the purpose of removing the bag from the receiving chamber, with a chamber opening closable by means of the chamber closure element on the one hand to the receiving chamber and on the other hand to the surroundings of the disposal station or a collecting container Disposal station opens. The compressed bags can be pushed out of the receiving chamber by means of the compression ram. For this purpose, the compression ram is shifted, for example, into an end position, with the chamber closure element of the receiving chamber preferably being opened and the bag being able to fall out. The chamber opening can either directly separate the receiving chamber from the surroundings of the disposal station, so that the bag emerges directly from the disposal station through the chamber opening, or the chamber opening is adjacent to a collecting container which adjoins the receiving chamber. In this collecting container, for example, several bags can initially be stored before, for example, a user removes them from the collecting container of the disposal station. The chamber opening together with the chamber closure element can be in the form of an openable vessel bottom, a displaceable drawer, a pivotable flap or the like.

Description of the embodiments

1 shows a disposal station according to the invention 1 which here for example as a base station for a vacuum cleaner 7th is designed to remove dirt, namely suction material, from the vacuum cleaner 7th in a receiving chamber 3 the disposal station 1 to be able to take over. A similar disposal station 1 can, however, also be designed to dispose of dirt from other containers, for example to dispose of dirt from household waste containers or the like.

The disposal station 1 assigns an interface 8th on which vacuum cleaner here 7th can dock. the interface 8th includes a dirt inlet opening 2 , to which a flow channel 4th and further the receiving chamber 3 connects. The flow channel 4th is a blower 15th assigned and a cyclone separator, not shown here, to separate dirt and dust particles from the air flow and into the receiving chamber 3 to be able to convict. In the receiving chamber 3 is a bag 5 arranged, which is preferably designed here as a disposable bag and after partial or complete filling from the disposal station 1 can be removed and disposed of. The receiving chamber 3 is a relocatable compression stamp 6th assigned which on the bag 5 can be lowered in order to compress it after filling and when opening a chamber closure element 17th into a collecting container 19th to move.

The vacuum cleaner 7th here is an automatically moving vacuum cleaner, namely a vacuum robot. However, the disposal station can 1 can also be designed to take over dirt from another cleaning device, for example also a cleaning device hand-operated by a user. The vacuum cleaner 7th has cleaning elements here in the usual way 16 for cleaning a floor area on driven wheels and a navigation device as well as associated sensors, not shown in detail, in order to be able to orientate oneself independently in its surroundings and to be able to move around.

2 shows a sketch of a receiving chamber 3 which is similar to the in 1 shown receiving chamber 3 is trained. The connection to the flow channel cannot be seen 4th to remove the dirt particles in the receiving chamber 3 to be deposited. In 2 is not a bag yet 5 into the receiving chamber 3 inserted, for example because a user has a bag filled with dirt 5 from the disposal station 1 and now a new, unfilled bag 5 into the receiving chamber 3 should be introduced. For this purpose is the receiving chamber 3 a storage facility 11 assigned which a variety of bags 5 stored, which are wrapped one behind the other around a roll. The individual bags 5 can lie loosely on top of one another or be connected to one another. In particular, an embodiment is suitable in which the bags 5 are easily separable and thus a first bag 5 a subsequent bag 5 pulls behind him. The separability of the bags 5 is achieved, for example, by perforating their connection areas. This perforation can be separated by pulling, pressing, cutting, exposure to heat or the like. The storage facility 11 can the bag 5 also store them in other ways. The storage shown here can for example be provided by bags lying on top of one another in a stack 5 or other replacement. The storage facility 11 is a sensor 14th assigned, for example an optical distance sensor, which detects a distance to the bag supply and thus gives an indication of the extent to which the diameter of the bag roll has already reduced. Alternative sensors 14th could also weigh the bag supply, or determine with the help of a light barrier or something similar. The receiving chamber 3 is also a feeding device 12th assigned, which here for example several (see 3 , 5 and 7th ) adjacent feeding elements 13th having. Two of the feeding elements 13th can be moved on a guide device 21st guided, here for example a rail guide. The feeding device 12th has a motor, for example, but can alternatively also be operated manually by a user, for example by manually operating a slide or the like. The feeding elements 13th the feeding device 12th can be designed as barbs, suction cups, locking means, grippers or the like. Part of the feed element 13th can advantageously be pivoted in order to grip a portion of a bag 5 to enable. Preferably the bag is 5 designed so that a first feed element 13th only grips one layer of the bag edges still lying on top of one another, while the other layer is taken by a further feed element 13th is held that its position to the receiving chamber 3 maintains, so that on opposite edge portions of the bag 5 attacking feed elements 13th move away from each other and thus an opening of the bag 5 can cause by pulling apart the edge subregions.

How the feeder works 12th is explained in more detail below. 2 first shows the compression stamp 6th , which through a telescopic change in length in the receiving chamber 3 can be shifted into it. The compression stamp 6th has an end, preferably plate-shaped contact area for exerting pressure on one in the receiving chamber 3 located bag 5 (in 2 not shown). The contact area of the compression ram 6th is preferably to a cross-sectional shape of the receiving chamber 3 customized. If the receiving chamber 3 is cylindrical, the end region of the compression ram 6th for example have a circular contact surface. Part of the compression stamp 6th has a closure device 9 for closing a bag filled with dirt 5 on. Here is the locking device 9 for example via a heating device 10 , by means of which a bag 5 can be closed at its edge areas. Unless the bag 5 for example, at least in the partial area which is from the heating device 10 is acted upon, has a plastic, the heating device 10 for example, weld the opposite bag layers together. Furthermore, the bag 5 also have an adhesive in this area, which by the action of heat from the heating device 10 can be activated, so that the opposite bag edge areas are then glued together. The compression ram is particularly advantageous 6th not only axially in the receiving chamber 3 displaceable, but also with respect to a radial direction, so that the heating device 10 on an inner wall of the receiving chamber 3 too can be moved. The control of the displacement of the compression ram 6th preferably takes place fully automatically by a control device of the disposal station 1 showing the process steps for compressing and sealing a bag 5 controls. These process steps include lowering the compression ram 6th into the receiving chamber 3 to the bag 5 to compress together with the dirt located therein, as well as a possibly radial displacement of the compression ram 6th to the heater 10 against the edge areas of the bag 5 to press, in particular using the inner wall of the receiving chamber 3 as a counter bearing.

The receiving chamber 3 furthermore has a chamber opening at the bottom 18th to remove a compressed bag 5 from the receiving chamber 3 on. The chamber opening 18th is during the filling of the bag 5 with dirt and during the compression and sealing process by means of a chamber closure element 17th closed. This chamber lock element 17th can be a flap, a movable floor section or the like. Here is the chamber locking element 17th for example a flap which can be pivoted about an axis of rotation and which is part of a chamber bottom. Below the chamber opening 18th according to this embodiment there is, for example, a collecting container 19th in which the compressed bag 5 can be passed. A receptacle opening 20th of the collecting container 19th can be opened manually by a user and, for example, be designed in the manner of a drawer, a pivoting flap or the like. According to one embodiment, the collecting container 19th For example, be dimensioned so that this a plurality of compressed bags laden with dirt 5 before the user can take up the collecting container 19th must drain.

The 3 to 8th show different displacement states of a bag 5 in the receiving chamber 3 , where in the 3 , 5 and 7th a top view of the receiving chamber 3 is shown. The 4th , 6th and 8th show a schematic side view of the feed device for the respective preceding figure 12th and a cut through the bag 5 . The feed device is shown 12th , which has a total of three feeding elements 13th has, namely two relative to the collecting chamber 3 displaceable and on a partial edge area of the bag 5 attacking feed elements 13th and a feed element designed as a suction cup 13th , which remains stationary and not like the other two feed elements 13th , along the guide device 21st via the receiving chamber 3 is relocated. As in 4th to see, is the one from the storage facility 11 removed bags 5 with superimposed edge sub-areas, of which a lower edge sub-area is longer than an upper edge sub-area in the cross-section shown. For this purpose, the upper edge partial area can be designed, for example, in such a way that it has recesses in the circumferential direction, which are in a folded state of the bag 5 , as in 4th For example, shown, lie on sections of the lower edge portion without a recess, so that a feed element 13th just one layer of the bag 5 (namely the lower one here), while the other layer of the feed element designed as a suction cup 13th is held. By the displaceable feed elements 13th now along the guide device 21st to the other side of the receiving chamber 3 be relocated, the bag will 5 across the cross section of the receiving chamber 3 stretched and at least partially opened. If necessary, you can open the bag 5 by a compressed air stream from the fan 15th the disposal station 1 get supported. The bag 5 is preferably on the inner wall of the receiving chamber 3 pressed so that a maximum volume is available for collecting dirt. If necessary, the bag can be unfolded 5 by lowering the compression ram 6th into the receiving chamber 3 and thus also in the bag 5 get supported.

The 9 to 14th show the compression and disposal of a bag filled with dirt 5 . The dirt is removed by means of the fan 15th into the receiving chamber 3 or the bag inside 5 promoted. For example, a cyclone separator removes the dirt from the air flow and thus enters the bag 5 . After filling the bag 5 , especially after reaching a certain predefined filling level of the bag 5 , becomes the bag 5 here, for example, from the displaceable feed elements 13th released so that the bag 5 only at an edge part area by means of the feed element designed as a suction cup 13th is held. The opposite edge sub-area thereby falls, for example, onto the held edge sub-area. This state is in 9 shown. The edge sub-areas lie loosely one above the other, namely preferably against an inner wall sub-area of the receiving chamber 3 leaned. This creates a displacement path for the compression ram 6th so released that the compression stamp 6th from the outside against the bag 5 can press and the bag 5 and the dirt it contains, as in 10 shown, compressed. Then the compression stamp 6th , as in 11 shown, again slightly from the bag 5 lifted off and in the radial direction on that part of the inner wall of the receiving chamber 3 moved to, at which the edge areas of the bag 5 are located. The compression stamp 6th will be like in 12th against the edge of the bag and thus also against the receiving chamber behind it 3 pressed. The control device of the disposal station 1 controls the heating device 10 of the compression stamp 6th so that the heater 10 is heated and the superposed peripheral portions of the bag 5 can be welded or glued together. Then the compression stamp 6th if necessary again moved radially away from the inner wall and in the direction of a bottom of the receiving chamber 3 relocated. This opens the chamber closure element 17th showing the chamber opening 18th releases to the compressed and sealed pouch 5 into the collecting container 19th to hand over.

According to another embodiment, it is only possible through the further displacement of the compression ram 6th a complete tearing off of the bag 5 from the other bags 5 the storage facility 11 take place with the subsequent bag 5 then so far into the receiving chamber 3 is guided in or is fed to this that the feed device 12th the bag 5 can take. This is followed by the following bag 5 the same procedure as explained before. The already filled bag 5 is in the collecting container 19th collected and can there through the collecting container opening 20th be taken through by a user.

To the depicted disposal station 1 Diverse embodiments are conceivable. For example, a feed element designed as a suction cup can be used 13th the bag 5 actively suck in by means of a negative pressure. An alternative would be a feed element 13th conceivable, in which, analogously to two fingers rubbing against each other, a first peripheral portion of the bag 5 against a second peripheral portion of the bag 5 moved so that gripping of only a partial edge area of the bag 5 becomes possible. To get one to seal the bag 5 suitable superimposition of the edge areas of the filled bag 5 to achieve, it can be provided that the inner wall of the receiving chamber 3 widening obliquely upwards, so that the portion of the bag to be sealed 5 does not fall down following gravity. If necessary, elements that increase frictional resistance, such as a rubber coating, can also be provided. According to a further embodiment variant, the displaceable feed elements could 13th the feeding device 12th Move back to an initial position and thus support the closing of the bag 5.
