Description

Waste treatment station

Technical Field

The invention relates to a waste treatment station having a dust and dirt inlet and a receiving chamber in fluid connection with the dust and dirt inlet, in which receiving chamber a bag for receiving dust and dirt is arranged, wherein the receiving chamber is provided with means for compressing dust and dirt present in the bag, wherein the receiving chamber has a compression punch which is displaceable relative to the bag such that the compression punch is pressed from the outside at least against an upper surface part area of the bag for compressing the bag together with dust and dirt present in the bag.

Background

The manner of the above-described waste treatment station is known in the art in a number of different embodiments.

In a particularly simple case, the waste treatment station is a waste container, for example capable of containing and compacting plastic waste, residual waste, organic waste, etc. To compress and dispose of the waste, the waste is placed through a dust inlet into a bag that is present in the receiving chamber. The dirt inlet can be connected here directly to the receiving chamber or can be connected thereto by means of a fluid channel.

For example, publication WO 00/54644A1 shows a special design of a waste treatment station. The waste treatment station has a receiving chamber to which a cleaner can be connected for receiving dirt collected in the cleaner. The bag and the dirt present therein are compressed, for example, by shrinking the bag after filling.

Furthermore, it is also known from the aforementioned publications that the receiving chamber is directly filled with dirt without the use of a bag, wherein the dirt is pressed together by means of a punch inside the receiving chamber and subsequently discarded in compression.

The disadvantage here is that the bags used either have to be compressible themselves or, when the bag is not used to compress dirt, even if compressed dirt masses are also produced, they are associated with the same hygiene risks, for example dust or dirt that is present in a loose state.

For example, DE 10 2010 016 256A1 discloses a vacuum cleaner having a bag filling device with a bag closure device and a separate compression ram.

Disclosure of Invention

The object of the present invention is to provide a waste treatment station for waste and/or grime, by means of which a simple compression and treatment of the waste and/or grime can be achieved.

In order to solve the above-mentioned technical problem, it is proposed that the compression punch has a closing device for closing the bag.

According to the invention, the compression punch of the waste treatment station has a closing device for closing the bag. The closing device is used for closing the bag in a dust-proof way as far as possible after the bag is filled with the dust, so that the dust, fine dust, smell and the like can not escape from the bag any more. Closing of the bag can be achieved, for example, via application of pressure or via warming. The closing of the bag is particularly preferably effected in the edge region of the bag, wherein the edge region can preferably have a special material for this purpose. For example, it is possible to apply an adhesive to the edge region, which adhesive can close the opposite peripheral region of the bag edge by pressure or temperature increase. According to one embodiment, the closing device can have a heating device. This heating device can activate the glue or alternatively also soften the material composition of the bag so that welding of the edge area can be achieved. According to this embodiment, the bag can thus be closed by welding. For this purpose, the heating device may have, for example, an activatable electric welding joint, as is known, for example, from so-called film welding apparatuses. The material of the bag is accordingly suitable for use in electric welding. It is sufficient when the relevant edge area is suitable for electric welding. Bags are often made of other materials, especially also sustainable materials. In a further embodiment, the bag can also be closed by gluing as described, for which purpose activatable glue is applied, for example, on the inner side of the wall, i.e. on the peripheral regions of the bag facing one another. In connection with this, for example, heat-activatable adhesives can be specified. The opening of the bag can be closed under the action of pressure and optionally heat. It is also possible that the bag is closed by means of a pressure lock, a clamping lock or velcro. In addition, the waste treatment station is designed so that the compression punches do not come into direct contact with the dirt to be compressed, but act externally on the bag in which the dirt is located. The dirt thus compressed is then already present in the bag in a sanitary package, which can then be further processed particularly simply and preferably without escaping dirt from the bag. In a particularly simple case, the user can remove the so-compressed bag from the containing chamber of the waste treatment station and discard it into a household waste container or bin or the like. In this case, the bag is preferably a disposable bag which is treated simultaneously with the dust. The bag may be made of different materials. For example, the bag can be a plastic bag. It is also possible that the bag is at least partly made of sustainable material, such as paper stock, paper shell, natural fibres or fabrics or other.

According to a particular embodiment, it may be provided that the waste treatment station is a base station for an electric vacuum cleaner, wherein the waste treatment station has an interface for interfacing with the electric vacuum cleaner, the interface having a dust and dirt inlet. According to this design, the waste treatment station is adapted to receive dirt from the dirt collection chamber of the cleaner. The electric vacuum cleaner can here be connected to the dirt opening of the waste treatment station, for example, with a suction nozzle which is used in a conventional suction operation of the vacuum cleaner to suck up dirt and grime, so that the suction present in the vacuum cleaner is transferred into the bag of the waste treatment station. For this purpose, it may be provided that the waste treatment station has a fan which is designed to apply a negative pressure to the dirt inlet. Thereby, the grime can be transferred from the grime inlet into the accommodation chamber. It is also possible to use a pressure fan, for example a fan of the cleaner itself, which is connected, for example by a valve, on its pressure side to the dirt opening of the waste treatment station, or the fan of the cleaner is operated in the opposite rotational direction, in order to transfer dirt from the cleaner into the waste treatment station. Alternatively, it is basically also possible for dirt to be transferred from the cleaner into the waste treatment station without the use of a fan, for example in that the dirt falls with gravity from a dirt collection chamber of the cleaner into a receiving chamber of the waste treatment station or into a bag arranged in the receiving chamber. The flow duct of the waste treatment station is preferably provided with a fan having a cyclone separator so that dirt reaching the flow duct through the dirt opening can be removed from the airflow and subsequently deposited in the bag. After the filling process at the waste treatment station has ended or when a certain filling degree of the bag and/or the receiving chamber has been reached, the bag together with the dust and dirt contained therein is compressed by means of a compression punch. The compression ram can be operated electromechanically, hydraulically, pneumatically, or in other ways and methods. In order to determine the degree of filling, a sensor is provided in the receiving chamber or in the bag, which sensor is capable of weighing, for example, the dust and dirt contained in the receiving chamber for detecting the dust and dirt contained therein. Alternatively, it is also possible to measure the filling degree of the bag optically. It can be provided, for example, that the bag is made of a material which is transparent to the wavelength of light with which the respective detection device is operated. It is also possible that a user of the waste treatment station manually triggers displacement of the compression ram, for example by touch pressing, operating a foot switch or the like. Dirt components, such as fine dust, which may escape from the bag during compression, are sucked away by the fans of the waste treatment station, wherein these dirt components are preferably intercepted by a filter element, such as an engine protection filter.

The connection between the waste treatment station and the attached vacuum cleaner or dirt container is preferably of an air tight design so that dirt can be transferred to the waste treatment station without affecting the user located at the side of the waste treatment station.

It is advantageously provided that a closing device is arranged on the partial region of the compression punch facing the bag. According to this embodiment, the compression punch is thereby used not only for compressing the bag or the dirt contained therein, but also for closing the bag. There is no need to provide two separate devices for compressing and closing the bag. Instead, the compression punch presses the bag on the one hand and closes the bag once the prescribed compression is reached on the other hand. The partial region of the compression punch that is moved toward the bag can have, for example, a heating element, in particular a resistance heating element. In this way the edge area of the bag can be heated and sealed. In this case, it is sufficient to heat only the partial region of the compression punch which actually rests on the bag.

According to the regulations, the waste treatment station has a storage device for storing a plurality of bags and/or the waste treatment station has a transport device for feeding bags into the receiving chamber, wherein the transport device is preferably designed for automatically transporting the bags. The holding device includes a storage in which a plurality of bags are stored. The bags can be wound up on a roll, for example, one after the other and separated from the other at a separation point preset for this purpose, in particular at the perforation. The separation of the bags can be achieved in a preferred embodiment by shearing, pulling, heating, tearing, etc. In addition, the bags can be stored in stacks, for example in stacks of bags, in a waste disposal station. In any event, the bags are stored in the store so that upon removal of the filled bags from the waste treatment station, the next unfilled bag can be replenished into the containment chamber. The closing means are preferably directly connected to the containing chamber so that the next bag can be fed along a particularly short path. The waste treatment station preferably has a transport device which is capable of taking bags out of the store and/or receiving them and transporting them into the holding chamber. When the waste treatment station has no storage means for bags, the transport means is preferably designed to receive bags manually placed into the waste treatment station by a user and to transport them into the containment chamber in a prescribed manner and method. The transport device may be provided with means for opening the bag, for example a fan of a waste treatment station, so that air is applied to the new bag so that it can be opened and here preferably on the inner wall of the receiving chamber. The transport device can be controlled fully automatically so that after a predetermined filling level of the bags is reached, new, unused bags are placed in the receiving chamber. The transport device may in particular be designed to assist in replenishing a new bag already present in the waste treatment station before the filled bag is removed when the filled bag is taken out of the receiving chamber.

The transport device preferably has at least one transport element displaceable relative to the receiving chamber for grasping and/or opening a partial region of the bag. For handling fresh bags, the transport device preferably has at least one transport element which acts (angreifend) on the bag. This transport element, which may be, for example, a clamping device, a hook, a suction cup or the like, holds and removes part of the edge region of the bag from the opposite part of the edge region, thereby opening the bag opening and eventually opening. The transport element can be provided with an operating element, for example a traction cable forming a mechanically acting connection or the like. The transport device preferably has a guide for the transport element, so that the supplementary movement of the bag and the opening movement of the bag are guided in a predetermined manner. The guide may be, for example, a rail guide, a chute guide, a groove guide, etc. The transport element may grasp a stack or roll of bags, for example, stored in a store of a waste treatment station. The transport element is then moved, for example along the guide means, towards the bag, where it grips, for example, part of the edge area and pulls it through the dirt inlet of the receiving chamber, so that the bag can be opened in the receiving chamber by the blowing air flow and/or is pressed into the receiving chamber also by the compression punch, preferably such that the bag rests from the inside against the inner wall of the receiving chamber and the available volume of the bag for receiving dirt is maximized. The transport device may also have two or more transport elements that act on opposite circumferential regions of the bag edge to pull the bag opening apart. One of the transport elements should be at least designed to be displaceable, wherein the other transport element is either fixed in position relative to the receiving chamber or the position relative to the receiving chamber is varied for this other transport element.

The storage means for storing the bags may be provided at different positions of the receiving chamber. For example, the storage device can be placed relative to the receiving chamber in such a way that the next bag to be fed into the receiving chamber is positioned in or on the region of the receiving chamber in which the compression punch enters the receiving chamber. This region preferably corresponds to the direction of entry of the dirt into the receiving chamber or pocket. Alternatively, the storage device can also be provided in a partial region of the receiving chamber facing away, i.e. for example such that the transport device grips the edge region of the next bag and then guides it, for example from the innermost partial region of the receiving chamber to the punch-side edge region of the receiving chamber.

After the bag has been filled with dirt, the bag is compressed by means of the compression punch in a controlled or automatic manner by the user, wherein either the transport element which expands the bag is moved back in advance, so that the displacement path for the compression punch in the receiving chamber is released, or the bag edge which is held firmly is released, i.e. released, so that the bag edge can preferably descend with gravity into the receiving chamber until it is folded or placed on another partial region of the bag, and the bag can then be closed by the closing device. It is also possible that the bag is released from the transport device by means of a compression punch. In this embodiment, it should be noted that the compression punch does not penetrate into the bag opening, but acts externally on a partial region of the bag, so that the bag is closed and compressed.

According to one embodiment, the storage device of the waste treatment station has a sensor which is designed to detect the storage of bags in the storage device. The sensor is designed and configured to detect the filling level of a reservoir having a bag. The sensor can be, for example, an optical sensor and a load cell. The sensor is preferably coupled to a control and analysis device of the waste treatment station which analyzes the detection signals of the sensor and identifies an impending or existing emptying condition of the bag store. The control and analysis means can then cause a message, for example on the screen of the waste treatment station, to be played or preferably to output a wireless signal to the user's external equipment with respect to the waste treatment station, thereby prompting the user that the bag reserve is running out or is about to end and that a new bag reserve should be introduced accordingly in the reserve means of the waste treatment station.

It may then be provided that the receiving chamber of the waste treatment station has a displaceable chamber closure element which is openable for removal of the bag from the receiving chamber, wherein the chamber opening closable by means of the chamber closure element is open on one side to the receiving chamber and on the other side to the surroundings of the waste treatment station or to a collecting container of the waste treatment station. The compressed bag may be ejected from the receiving chamber by a compression punch. For this purpose, the compression punch is displaced, for example, into a final position, wherein the chamber closure element of the receiving chamber is preferably opened and the bag can be dropped out. The chamber opening of the receiving chamber is here either directly isolated from the environment surrounding the waste treatment station, so that the bag exits the waste treatment station directly through the chamber opening, or the chamber opening adjoins a collecting container which is connected to the receiving chamber. In this case, it is possible to store a plurality of bags, for example, in a collection container, and then to remove the bags from the collection container of the treatment station, for example, by a user. The chamber opening together with the chamber closing element can take the form of an openable container bottom, a slidable drawer, a pivotable lid or the like.

Detailed Description

Fig. 1 shows a waste treatment station 1 according to the invention, which is configured here as a base station for a vacuum cleaner 7, for example, so that dirt, i.e. suction, can be transferred from the vacuum cleaner 7 into the waste treatment station 1. However, a similar waste treatment station 1 can also be designed for the treatment of dust from other containers, for example dust from household waste bins or the like.

The waste treatment station 1 has an interface 8 on which interface 8a vacuum cleaner 7 can be docked. The interface 8 contains a dust inlet opening 2 to which the fluid channel 4 is connected and further to which the receiving chamber 3 is connected. The fluid channel 4 is provided with a fan 15 and a cyclone, not shown in detail here, so that dirt and dust particles can be separated from the air flow and conveyed into the receiving chamber 3. A bag 5 is arranged in the receiving chamber 3, which bag 5 is preferably designed here as a disposable bag and can be removed from the waste treatment station 1 after partial or complete filling and discarded. The receiving chamber 3 is provided with a displaceable compression punch 6, which compression punch 6 can be lowered onto the bag 5, so that the bag 5 is compressed after filling and moves it into the collecting container 19 when the chamber closure element 17 is opened.

The vacuum cleaner 7 is a self-propelled vacuum cleaner, i.e. a vacuum robot. However, the waste treatment station 1 may also be used to house dirt from other cleaning devices, for example cleaning devices that may also be designed to be manually guided by a user. The vacuum cleaner 7 has here a cleaning element 16 for cleaning the floor in a conventional manner and manner, as well as drive wheels and navigation devices, not shown further, and a corresponding sensor system, so that it can be positioned and advanced by itself around it.

Fig. 2 schematically shows a representation of a receiving chamber 3, which receiving chamber 3 is constructed similarly to the receiving chamber 3 shown in fig. 1. Unidentifiable are connections on the flow conduit 4 for separating dirt particles in the receiving chamber 3. In fig. 2, the bag 5 has not been placed in the receiving chamber 3, for example because the user has taken the dirt-filled bag 5 from the waste treatment station 1 and now should place a new, unfilled bag 5 into the receiving chamber 3. For this purpose, the housing chamber 3 is provided with a storage device 11 which stores a plurality of bags 5 which are wound successively on a roller. Each bag 5 can be stacked here at random or can be connected to each other. A design is particularly suitable in which the bags 5 can be connected to each other in an easily separable manner, so that the first bag 5 drags the following bag 5 behind it. The separability of the bags 5 is achieved, for example, by perforation of their connection areas. The perforations can be separated by pulling, pressing, shearing, heating, etc. The storing means 11 can store the bags 5 in other ways and methods. The storage device shown here can be replaced, for example, by bags 5 placed in a stack-like manner or otherwise. The holding device 11 is provided with a sensor 14, for example an optical distance sensor, which detects the distance to the bag holding and thus provides an indication as to how much the diameter of the bag roll has been reduced. The alternative sensor 14 can also weigh the bag stock or be determined by means of a grating or the like. The receiving chamber 3 is additionally provided with a transport device 12, which transport device 12 here has, for example, a plurality of transport elements 13 lying next to one another (see fig. 3, 5 and 7). Two of the transport elements 13 are displaceably guided on guides 21, in this case for example rail guides. The transport device 12 has, for example, a motor, alternatively also manually operated by a user, for example by manually operating a slide or the like. The transport element 13 of the transport device 12 may be configured as a barb, suction cup, locking means, clamping device or the like. In order to achieve a gripping of a part-area of the bag 5, the part-area of the transport element 13 may advantageously be pivotable here. The bag 5 is preferably designed such that the first transport element 13 only catches one layer of the edges of the bags still stacked, while the other layers are held by the further transport element 13, which further transport element 13 keeps its position to the receiving chamber 3 unchanged, so that the transport elements 13 acting positively on opposite edge part areas of the bag 5 are moved away from each other, so that the bag 5 can be opened by pulling the edge part areas apart.

The functionality of the transporter 12 is further described below. Fig. 2 first shows in addition a compression punch 6, which compression punch 6 is displaceable within the receiving chamber 3 by a telescopic length change. The compression punch 6 has a preferably plate-shaped contact area on the end side for exerting pressure on a bag 5 (not shown in fig. 2) located in the receiving chamber 3. The contact area of the compression punch 6 is preferably adapted to the cross-sectional shape of the receiving chamber 3. If the receiving chamber 3 is configured as a cylinder, the end of the compression punch 6 can have a contact surface, for example, which is circular. A partial region of the compression punch 6 has a closing device 9 for closing the dirt-filled bag 5. The closing device 9 has, for example, a heating device 10, by means of which the bag can be closed in its edge region. The heating device 10 can weld the opposing bag layers if the bag 5 has plastic, for example, at least in the partial region where the heating device 10 is acting. In addition, the bag 5 can also have adhesive in this region, which can be activated by the heating action of the heating device 10, so that the bag edge regions lying opposite one another are glued to one another. It is particularly advantageous if the compression punch 6 is displaceable in the receiving chamber 3 not only axially but also in the radial direction, so that the heating device 10 can be moved towards the inner wall of the receiving chamber 3. The control of the displacement of the compression punches 6 is preferably effected fully automatically by the control means of the waste treatment station 1 which control the method steps for compressing and packaging the bags 5. Furthermore, the method step comprises lowering a compression punch 6 in the receiving chamber 3 for compressing the bag 5 together with dirt present in the bag 5 and, if necessary, radially displacing the compression punch 6 for pressing the heating device 10 against the edge region of the bag 5, in particular if the inner wall of the receiving chamber 3 is used as a support.

The receiving chamber 3 also has a chamber opening 18 on the bottom side for removing the compressed bag 5 from the receiving chamber 3. The chamber opening 18 is closed by means of the chamber closing element 17 when the bag is filled with dirt and during the compression and encapsulation process. This chamber closing element 17 may be a cover or a displaceable bottom part-area or the like. The chamber closing element 17 is here, for example, a cover pivotable about a rotation axis, which cover is part of the bottom of the chamber. According to the present embodiment, a collecting container 19 is illustratively located below the chamber opening 18, into which collecting container 19 the compressed bag 5 can be transported. The collection container opening 20 of the collection container 19 can be opened manually by a user and can be configured, for example, in the manner of a drawer or pivotable lid or the like. According to one embodiment, the collection container 19 can be dimensioned, for example, such that it can collect a plurality of compressed, dirt-laden bags 5 before the user has to empty the collection container 19.

Fig. 3 to 8 show different displacement states of the bag 5 in the receiving chamber 3, wherein fig. 3, 5 and 7 show top views on the receiving chamber 3. Fig. 4, 6 and 8 show a side view of the conveyor 12 and a section along the bag 5, with respect to the respective front figures. The figure shows a transport device 12, wherein the transport device 12 has a total of three transport elements 13, namely two transport elements 13 which are displaceable relative to the receiving chamber 3 and act on a partial edge region of the bag 5, and one transport element 13 which is embodied as a suction cup, the transport element 13 being embodied as a suction cup, the position of which remains unchanged and is different from the other two transport elements which are displaced along the guide device 21 in the receiving chamber 3. As can be seen in fig. 4, the bags 5 taken out of the store 11 have a stacked edge part region, the lower edge part region of which is longer in the cross section shown than the upper edge part region. For this purpose, the upper edge part region can be designed, for example, in such a way that it has a recess in the circumferential direction, which, in the folded state of the bag 5, rests on a section of the lower edge part region without a recess, as shown by way of example in fig. 4, so that the transport element 13 can only grasp one layer of the bag 5 (i.e. the lower layer in this case), while the other layers are held by the transport element 13 in the form of a suction cup. As the displaceable transport element 13 is now displaced along the guide means 21 towards the other side of the receiving chamber 3, the bag 5 is unfolded via the cross section of the receiving chamber 3, thereby being at least partially opened. Opening of the bag 5 can be supported by the forced air flow of the fan 15 of the waste treatment station 1 if necessary. The bag 5 is preferably pressed against the inner wall of the receiving chamber 3 so that the available receiving capacity for receiving dirt is maximized. The deployment of the bag 5 can be assisted if necessary by the lowering of the compression punch 6 in the housing chamber 3 and thus also in the bag 5.

Fig. 9 to 14 show the compression and treatment of the bag 5 filled with dirt. The dirt is transported by means of a fan 15 in the receiving chamber 3 or in a bag 5 located therein. Dirt is removed from the airflow by, for example, cyclonic separation to reach the bag 5. After filling the bag 5, in particular after a specific, predetermined filling level of the bag 5 has been reached, the bag 5 is released here, for example, from the displaceable transport element 13, so that the bag 5 is held only in the edge region by means of the transport element 13 in the form of a suction cup. The opposite edge part region thus drops over the held edge part region, for example. This state is shown in fig. 9. The edge part regions are stacked sporadically, i.e. preferably rest against the inner wall part regions of the receiving chamber 3. Thereby, the position change path for the compression punch 6 is released so that the compression punch 6 can be pressed toward the bag 5 from the outside and compress the bag 5 and dust and dirt located therein, as shown in fig. 10. Subsequently, as shown in fig. 11, the compression punch 6 is lifted slightly from the bag 5 again and moves in the radial direction towards the partial region of the inner wall of the receiving chamber 3 where the edge region of the bag 5 is located. The compression punch 6 presses against the edge of the bag as shown in fig. 12 and thus also against the rear receiving chamber 3. The control means of the waste treatment station 1 control the heating means 10 of the compression punches 6 so that the heating means 10 are heated and are able to weld or adhere to each other the circumferential part-areas of the stack of bags 5. The compression punch 6 is then, if necessary, displaced radially from the inner wall and in the direction of the bottom of the receiving chamber 3. Thereby opening the chamber closure element 17, which chamber closure element 17 releases the chamber opening 18 so that the compressed and welded bag 5 is transported into the collecting container 19.

According to a further embodiment, the complete tearing of the bag 5 from the other bags 5 of the storage device 11 can be achieved firstly by a continuous displacement of the compression punch, wherein the subsequent bags 5 are transported into the receiving chamber 3 or toward the receiving chamber 3 until the transport device 12 can grasp the bags 5. The same procedure as before is then followed with the subsequent bags 5. The bag 5 that has been filled is collected in the collection container 19 and removed therefrom by the user through the collection container opening 20.

Various embodiments are conceivable with respect to the illustrated waste treatment station 1. The transport element 13, which is configured as a suction cup, is capable of actively sucking the bag 5 by means of low pressure. Alternatively, a transport element 13 is also conceivable in which transport element 13 the first circumferential part-area of the bag 5 is moved away from the second circumferential part-area of the bag 5, like two mutually rubbed fingers, so that only one partial edge area of the bag 5 can be gripped. In order to achieve a stack of edge regions of the filled bag 5 suitable for enclosing the bag 5, it can be provided that the inner wall of the receiving chamber 3 extends obliquely upwards so that the partial region of the bag 5 to be enclosed does not fall down with gravity. If necessary, elements which increase the frictional resistance, such as rubber elements, can also be provided. According to a further embodiment, the displaceable transport element 13 of the transport device 12 can be moved back into the starting position, so that the closing of the bag 5 is supported.
