Description

Austrian Patent Office AT 13 526 Ul 2014-02-15

Description: The invention relates to a device for comminuting solid and substantially dry domestic waste, in particular plastic packaging, such as polyethylene terephthalate (PET) and / or sheet metal, such as aluminum sheet. The device comprises a housing suitable for installation in a kitchen appliance, in particular in a kitchenette or a kitchen cabinet, and / or for installation in a kitchen, and a comminution unit housed in the housing with at least one feed opening for the domestic waste to be comminuted and a plurality of rotatable comminuting means. Furthermore, the comminution device comprises a collecting unit accommodated in the housing below the comminution unit, with at least one receptacle for the comminuted household waste.

In a modern household falls in particular due to the many packages of plastic or sheet metal at regular intervals a large amount of household waste. In particular, the containers contained in household waste, such as PET bottles or aluminum cans, are often very bulky and require a relatively large amount of space for their weight, since they are often not compressed or compressed before being fed to a waste collection system. This brings a frequent disposal of household waste in the local collection station with it or makes large waste containers with a corresponding capacity required. As a result, the large volume of household refuse often leads to a regularly occurring overfilling of collecting stations and drives up the costs of waste disposal for both the private household and for the disposal companies.

Another important aspect is the revaluation of at least part of the accumulated household waste. In this context, it is particularly important to separate household waste as reliably as possible into its various basic materials, such as different types of plastic, metal, white and stained glass, paper and biowaste, and to feed the recovered raw materials to the respective recycling process.

In order to achieve a reduction of the volume or a compression of at least a portion of household waste and a complete sorting as possible in the basic materials, it is proposed in the prior art, inter alia, at least a portion of household waste, in particular the plastic and sheet metal waste, to be fully automatically shredded in households and divided or separated into the different, recyclable precursors or raw materials. The raw materials are then returned to industry for reuse.

Various devices for comminution and fractionation of household waste are known from the prior art. These shredders are intended for immediate use in the home, so right where the household waste is generated. For example, DE 102 36 710 A1 shows a comminuting device for household waste comprising a comminution unit and a collecting unit arranged thereunder. The described crushing device can be pulled out of a kitchen cabinet along side-mounted rails and the household waste to be shredded is introduced into the shredder via an opening at the top of the shredding device. The shredding unit comprises at least two roller-type separating means, which comminute the input household waste and forward it to the collecting unit arranged thereunder, where the shredded household waste is deposited. The release agent of the crushing unit can be removed by simple means from the crushing device and thus can be cleaned in a simple manner.

From DE 41 14 751 C2 an apparatus for cutting and breaking empty containers in small pieces of material is known. The material to be crushed is fed from above into the device and cut or broken by standing cutting rollers. The thus shredded materials continue to move down the device and fall through an opening into one of several garbage containers which has been positioned under the opening with a mechanical actuator.

Also, from DE 43 27 127 A1 a recycling device, in particular for use in the household, known, which recycling device comprises a sensor unit for determining the supplied material. It is envisaged, in accordance with the output signal of the sensor unit, to cut or break the supplied material, optionally to compress it and feed it according to the detected material to the respective packaging unit where the shredded and separated material is packaged for further use. For this recycling device is further described a cleaning and / or sterilization device, which ensures a hygienic condition of the recycling device.

All these crushing devices have the disadvantage that either the crushing unit and often other parts of the crushing device must be pulled out of a housing or cabinet each time before use and / or that the feed opening for the material to be crushed at the top of the Crushing device is arranged so that, for example, when a preparation of the crushing device in a kitchen, the top of the crushing device can not otherwise be used, for example, as a storage area.

It is therefore an object of the invention to overcome these disadvantages when using a conventional crushing device.

This object is achieved with a device of the type mentioned above in that the at least one feed opening of the crushing unit is accessible via a front side of the housing and the household waste to be shredded is input substantially horizontally from the front, and that at least part of the collecting unit and / or a part of the housing is movable forward from the housing, so that the at least one collecting container is accessible from the front of the housing.

In this way, a device for crushing solid and substantially dry household waste is created, which allows a particularly comfortable use and also very well suited for installation in a kitchen equipment and / or installation in a kitchen, as on the at least one feed opening of the comminution unit and the at least one receptacle of the catcher unit can be accessed from the front side of the housing of the comminution device. If the crushing device is housed in a kitchen cupboard or the like, the housing or the crushing unit of the crushing device does not have to be pulled out of the kitchen cupboard each time during use first and then moved back again. This particularly increases the user-friendliness of the comminution device. Likewise, in an embodiment of the crushing device as a free-standing Aufstellgerät the top of the crushing device or the housing for a different use, for example, as a storage or working surface, free. This ensures in particular a more efficient use of space or space in a kitchen. Extraction of at least a portion of the collecting unit is necessary at most when emptying the at least one collecting container.

Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

It is advantageous if an upper, if necessary wegbewegbare cover device, in particular a cover, at the front of the housing which closes at least one feed opening and a lower, if necessary wegbewegbare cover device conceals the collecting unit in a closed state in the housing at the front of the housing , On the one hand, this ensures the easy and at any time accessibility of the at least one feed opening of the comminuting device and the at least one receptacle in the catching unit from the front side of the housing of the comminution device, and on the other hand, in particular in connection with a securing device, the AT13 526U1 2014-02-15

Security of use of the crushing device and in particular the safety of children sufficiently given.

It is also favorable if, in a wall of the housing and / or in the upper and the lower cover device and / or in a closed state between the housing and the covering devices, insulating and / or sealing elements are arranged. In this way, the odor and / or noise pollution outside the shredding device is minimized.

It is particularly advantageous if the rotatable crushing means, in particular comminution rollers, mesh in pairs in the comminution unit and the household refuse to be shredded is transported substantially vertically through the comminuting means and thereby processed, and if between the at least one feed opening and the comminuting means Shredding unit preferably a feed device is arranged. In this way, the household refuse, which is supplied substantially horizontally into the at least one feed opening, is comminuted in the comminution unit by the comminution means substantially along a vertical processing direction. This combines the advantages of a substantially horizontal input of household waste from the front into the comminution device with the advantage of a substantially vertical processing direction of the household waste in the comminution unit, whereby a simple further transport of shredded household waste is ensured by gravity alone in the at least one receptacle of the collecting unit , For transporting the domestic waste to be comminuted from the at least one feed opening of the comminution device to the comminution means of the comminution unit, a feed device is preferably provided.

It is also advantageous if in the crushing unit three or more crushing rollers are formed in series next to each other and each of the juxtaposed crushing rollers mesh with each other, wherein a direction of rotation of the crushing rollers is reversible. In a first, advantageous embodiment, the end faces of the comminution rollers are arranged along a line. In an alternative, advantageous embodiment of at least one group of three juxtaposed crushing rollers, the middle crushing roller is offset from the line down and the end faces of the other two crushing rollers are arranged along the line. In this way, it is possible to realize with the crushing rollers of the crushing unit different processing options and sorting by the shredding household waste is preferably supplied to the corresponding pair of rollers and thus a certain processing area with the feeder and, if necessary, the direction of rotation of the comminuted crushing rollers is reversed so that the household waste to be shredded is processed vertically downwards. Down-centered comminution rollers reduce the linear expansion of the comminution rollers in series, thus minimizing the size of the comminution unit.

It is also advantageous if at least one of the downwardly offset crushing rollers arranged opposite the two adjacent, not offset down crushing rollers increased diameter. In this way, a shredding unit is provided which has a greater distance between the two adjoining, non-downsized crushing rollers, so that even larger pieces of waste between the two spaced, adjacent crushing rollers can be transported through to the underlying processing areas of the pairs of rollers.

It is also particularly advantageous if at least one of the axes of rotation of a pair of crushing rollers is held with a spring device of certain strength in a rest position. In this way, at least one of the crushing rollers of a pair of rollers in case of overload, for example in the supply of a solid, metallic object, dodge to the side and an overload, clogging and / or damage of the crushing device is actively prevented. [0019] It is also advantageous if the roll disks of the comminution rollers have a spacing in the axial direction of between 1 mm and 30 mm. In this way, sufficient comminution and thus volume reduction of household waste is ensured, since the average grain size of the shredded household waste is in the range of the selected distance of the roll disks.

Finally, it is advantageous if the collecting unit comprises a plurality of collecting container and preferably a sorting unit between the crushing unit and the collecting unit of the crushing device is arranged, which sorting unit automatically directs the different types of shredded household waste into the respective collecting container. In this way, a comprehensive separation and thus more efficient recyclability of shredded household waste is ensured. Due to the design of the sorting unit, it is also possible, for example, only one crushing roller pair and thus only one processing area to distribute the shredded household waste on a plurality of collecting containers, so that a separation into different basic materials is performed. Finally, the convenience and ease of use of the shredder are increased by the fully automatic detection and sorting of household waste.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

In each case in a highly simplified, schematic representation: FIG. 1 FIG. 2 a [0025] FIG. 2 b [0026] FIG. 3 FIG. 4 a 4 a external perspective view of a crushing device; a side view of the crushing device of Figure 1 with the side wall open. a front view of another embodiment of the crushing device of Figure 1 with removed covering devices. a detailed plan view of the crushing rollers of the crushing unit of Fig. 2a; a side view of a possible embodiment of the crushing rollers and a side view of another embodiment of the crushing rollers.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis transferred to like parts with the same reference numerals or the same component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

Fig. 1 shows a device 1 for crushing solid and substantially dry household waste 2 in a housing. 3

According to a first embodiment, the housing 3 of the crushing device 1 is designed so that it is suitable for installation in a kitchen appliance or kitchenette and thus in particular in one of the base cabinets of the kitchen equipment. The outer dimensions of the housing 3 are thus based on the current standards or standard values for fitted kitchens. The housing 3 therefore has, viewed from a front side 4, preferably a width of 45 cm or 60 cm, a maximum depth of 60 cm and a height of approximately 85 cm.

According to a further embodiment, the housing 3 is designed so that the crushing device 1 is suitable for free installation in a kitchen.

The outer dimensions of the housing 3 are substantially equal to the 4/15 Austrian Patent Office AT13 526U1 2014-02-15

External dimensions of the built-in device described above. An outer side 5 of the housing 3 is, however, adjusted in function and appearance of the free installation of the crushing device 1.

In the housing 3 of the crushing device 1 is located in a first, preferably upper level 6, a control and operating unit. This unit comprises the necessary electronic components for the control and operation of the crushing device 1. At the front 4 of the control and operating unit controls 7 and display elements 8 are formed.

In Fig. 2a, a side view of the crushing device 1 is shown with an open side wall.

In this illustration, it can be seen that in a second, preferably middle plane 9 of the comminution device 1, a comminution unit 10 comprising a feed device 11 and a plurality of rotatably mounted comminution means 12, in particular comminution rollers 13, is formed. The feed device 11 has at least one feed opening 14 on the front side 4 of the comminution device 1, via which feed opening 14 the household waste 2 to be comminuted is fed into the feed device 11 and transported further by the latter to the comminuting means 12, where the household waste 2 is comminuted.

The crushing means 12 and crushing rollers 13 are preferably electrically driven via at least one electric motor, which derives its energy from the domestic electricity network, and engage in pairs. In each area where two adjacent crushing means 12 and crushing rolls 13 intermesh, a processing area 15 of the crushing unit 10 is formed. Household refuse 2 can in principle be supplied to each processing area 15 and comminution by the comminution means 12 or comminution rollers 13 takes place there.

The comminuted household waste 2 then passes into a lower level 16 in the housing 3 of the comminuting device 1, in which lower level 16 a collecting unit 17 is accommodated. The collecting unit 17 comprises at least one collecting container 18 for the comminuted household waste 2.

The at least one feed opening 14 of the comminution unit 10 is accessible via the front side 4 of the housing 3 and the household waste 2 to be comminuted can be introduced substantially horizontally from the front into the comminution device 1 or the feed opening 14 of the comminution unit 10. The feed opening 14 is preferably closed by an upper, if necessary wegbewegbare cover 19, in particular a cover, on the front side 4 of the housing 3. The upper covering device 19 can be folded downwards, in particular via hinges 20 and by means of a handle 24, so that the household refuse 2 to be comminuted can be entered into the feed opening 14 of the comminution unit 10 in a simple manner.

At least a portion 44 of the collecting unit 17 is pulled out via a rail and roller device 21 forward from the housing 3, wherein when moving out of the part 44 of the collecting unit 17 of at least one collecting container 18 with forward or out of the housing 3 out is moved so that the at least one collecting container 18 from the front side 4 of the housing 3 is accessible. At the front of the extendable part 44 of the collecting unit 17, a lower cover device 22 with a pull-out handle 23 is attached. When closed, the lower cover device 22 conceals or closes the collecting unit 17 in the housing 3 of the comminuting device 1.

The crushing device 1 or its housing 3 is supported in particular by means of height-adjustable support elements 25 with respect to a lower support level 26, in particular a floor, spaced.

According to a particularly advantageous embodiment, in the walls 27 of the housing 3 and in the upper cover 19 and the lower cover 5/15 Austrian Patent Office AT 13 526 Ul 2014-02-15 22 not shown insulation elements, in particular for noise reduction, housed , In particular in order to avoid odor nuisance outside the comminution device 1, it is expedient to attach a sealing element 28 to the housing 3 of the comminution device 1 in such a way that the sealing element 28 between the housing 3 and the upper cover device 19 or the lower cover device 22 in the closed state of the comminuting device 1 is arranged.

As can be seen in Figs. 2a and 3, the crushing unit 10 comprises in a possible embodiment, three crushing rollers 13, the axes of rotation 29 are arranged parallel and in a horizontal plane adjacent to each other, so that each of the adjacent crushing rollers 13 with their outer peripheral portions 30 in pairs ineinan-dergreifen. As already mentioned, each area in which the comminution rollers 13 intermesh each forms a processing area 15. Conveniently, the household refuse 2 to be comminuted is transported substantially vertically through the comminution rollers 13 or through the processing areas 15 and thereby processed or comminuted.

Thus, in the currently used processing area 15, the processing direction extends from top to bottom, a direction of rotation 31 of the crushing rollers 13 is reversible as needed. The respective directly next to each other and intermeshing crushing rollers 13 have opposite directions of rotation 31 in each case.

In order to transport the household waste 2 to be comminuted into the desired processing area 15 between the comminuting rollers 13, in the embodiment according to FIG. 2a at least part 45 of the feed device 11 is designed to be movable. The formation of a plurality of processing areas 15 serves, in particular, to carry out a sorting or fractionation of the comminuted household waste 2. Depending on the type of household waste 2 to be comminuted, the corresponding processing area 15 is selected by means of the movable feed device 11 and the household refuse 2 is transported there. In each case a collecting container 18 is arranged below the respective processing region 15, in which the respective type of shredded domestic waste 2 is collected. Due to the vertical working direction of the processing areas 15 of the comminuting rollers 13, the fractions of the comminuted household refuse 2 fall solely by gravity into the corresponding receptacle 18 arranged below the respective processing area 15.

In principle, the feeding device 11 comprises feed means, not shown, such as conveyor belts and driven rollers for further transport of the domestic waste 2 to be comminuted to the respective processing area 15 of the comminution rollers 13.

If with a certain number of processing areas 15 an exceeding number of fractions can be formed and sorted into the corresponding receptacle 18, which is particularly advantageous for cost and / or space reasons, is in the lower level 16 of the crushing device 1, between the crushing unit 10 and the collecting unit 17, a sorting unit 32 is arranged. This sorting unit 32 is movable and distributed depending on the position, the different types of shredded household waste 2 on the currently selected collection container 18th

According to a particularly advantageous embodiment, a movable feeder 11 or a sorting unit 32 or a combination of movable feeder 11 and sorting unit 32 automatically distributes the shredded household waste 2, depending on its type, to the respective collection bin 18. The respective type of household waste 2 is thereby For example, determined by means of a sensor, not shown, in the feeder 11 and the movable part 45 of the feeder 11 and / or the sorting unit 32 is controlled accordingly. Such a sensor can be used, for example, for the optical recognition of the respective plastic (transparent, colored, etc.) or for reading out corresponding barcodes or radio transponders on the packaging.

The orientation of the axes of rotation 29 of the comminution rollers 13 shown in FIG. 2a represents a first expedient embodiment. It is also possible to determine the direction of the axes of rotation 29 according to another expedient embodiment to rotate in the horizontal plane by 90 °, as shown in Fig. 2b. In Fig. 2b, a crushing device 1 is shown in front view with removed covering devices 19, 22, wherein in turn for the same parts the same reference numerals or component designations as in the preceding Fig. 2a are used. In order to avoid unnecessary repetition, reference is made to the detailed description of the preceding Fig. 2a or reference.

Explicitly, however, it should be mentioned in relation to the embodiment of the comminution device 1 according to FIG. 2b that the mode of operation or direction of movement of a preferably existing, in particular movable, feed device 11 or a preferably present sorting unit 32 is to be correspondingly adjusted or likewise rotated by 90 ° , Further, by adding further crushing rollers 13 in the case of arranging the rotary shafts 29 as shown in Fig. 2a, the depth of the housing 3 of the crushing device 1 increases, whereas in the case of arranging the rotary shafts 29, as in Fig. 2b, the width of the housing 3 increases.

In the concrete case, the crushing device 1 of FIG. 2b is designed without a feeding device 11 and with a sorting unit 32. The household refuse 2 to be shredded is manually entered by a user of the comminution device 1 after the top cover 19 has been folded away, via the respective feed opening 14, 14 "into one of the chambers 46, 47 via the corresponding processing areas 15 of the comminuting rollers 13.

The two chambers 46, 47 are separated from each other by a wall element 48. After closing the upper cover 19 and / or after a corresponding operation by the user, the crushing operation starts and the sorting unit 32 transports the shredded household waste 2 into the selected receptacle 18. For setting the operation, preferably above each of the chambers 46, 47 in FIG upper level 6, which upper level 6, the control and operating unit of the crushing device 1, each having a corresponding operating element 7, in particular in each case a switch or button arranged.

In the illustrated embodiment, the left chamber 46 and the three corresponding left side crushing rollers 13 for the plastic waste (for example, a processing area 15 for the transparent plastic and a processing area 15 for the remaining plastic) and the right chamber 47 and the two corresponding, right-side crushing rollers 13 provided for the waste metal or aluminum sheet. Depending on the requirements and number or arrangement of the processing areas 15, only one chamber 46, 47 or more than two chambers 46, 47 may be formed, wherein a respective wall element 48 is arranged between each of the chambers 46, 47.

According to an alternative, not shown embodiment, the two right side crushing rollers 13 are shown in Fig. 2b, which crushing rollers 13 are provided for processing the sheet waste from the right chamber 47 of the crushing device 1, also in its processing area 15 is slightly spaced, so that a Sheet metal pressing device is realized. The spacing is in particular in a range of 1 mm to 10 mm.

The outer right crushing roll 13 may in such a case also function as a closed cylinder without individual roll disks 38, i. be executed with a continuous, closed shell section. Similarly, it is possible with basically intermeshing or meshing, right-side crushing rollers 13, the axis of rotation 29 of the extreme right crushing roller 13 to form movable side, so that the two right-side crushing rollers can be spaced as required and cut the waste of metal or aluminum sheet optionally (with intermeshing crushing rollers 13) or pressed (with spaced crushing rollers 7/15 Austrian Patent Office AT13 526U1 2014-02-15 13).

In Fig. 4a, a crushing unit 10 with four juxtaposed crushing rollers 13 is shown. The end faces 33 of the crushing rollers 13 are arranged along a line 34.

In the exemplary embodiment illustrated in FIG. 4a, all the comminuting rollers 13 intermesh, so that three processing areas 15 are formed. Likewise, it is possible not to form a middle processing area 35 and to arrange the two corresponding middle crushing rollers 36 at a distance, so that these comminution rollers 36 do not mesh with one another. This serves, in particular, to form a comminution unit 10 having a plurality of processing areas 15 with different roller pitches for producing comminuted bottled waste 2 having a different particle size.

As can be seen in Fig. 3, the roller pitch is given by a distance 37 of roller disks 38 of a crushing roller 13 in the axial direction. The roller pitch or the distance 37 defines the grain size of the shredded household waste 2 directly. According to a particularly expedient embodiment, the distance 37 of the roller discs is set with a value between 1 mm and 30 mm.

FIG. 4b shows a further embodiment of a comminution unit 10 with six comminution rollers 13. In this case, in each case a group of three juxtaposed crushing rollers 13, the middle crushing roller 39 offset from the line 34 down and the end faces 33 and rotation axes 29 of the remaining crushing rollers 13 are arranged along the line 34. In this way, in particular the dimensions of the comminution unit 10 are reduced, since the comminution rollers 13 move closer together in one direction.

The comminution unit 10 according to FIG. 4b comprises five processing areas 15. As already described for the comminution rollers 13 of FIG. 4a, it is also possible here not to form, for example, the middle processing area 35 between the middle comminution rollers 36 and the two middle comminuting rollers 36 spaced so that two groups of processing areas 15 are formed with different roll pitch for the production of shredded household waste 2 with different grain sizes.

As shown in Fig. 4b, it may also be useful if at least one of the downwardly offset crushing rollers 39 has a comparison with the two adjacent arranged, not offset down crushing rollers 13 enlarged diameter 41.

In Fig. 3 is exemplified for three crushing rollers 13 that expediently at least one of the axes of rotation 29 of a pair of intermeshing crushing rollers 13 with a spring device 42 of certain strength in the illustrated rest or. Working position is maintained. In the rest or working position of the rotary axes 29, the comminution rollers 13 engage in pairs in each other and when a supply of household waste 2 in the designated processing areas 15 of this is comminuted. The spring force of the spring device 42 is chosen to be correspondingly large, so that when a supply of comminuted household waste 2, the crushing rollers 13 remain in the rest or working position. Now, if a non-crushable object, such as a solid metal part, introduced into the crushing unit 13, so it is drawn in the respective processing area 15 between the two corresponding crushing rollers 13 and the crushing roller 13 with a movable axis of rotation 29 moves to the side in an evasive position, not shown. Due to the distance between the two comminution rollers 13 forming in the process, the object which can not be comminuted can pass through the comminution unit 10 and in particular the comminuting rollers 13 without damaging or destroying the comminuting device 1. After the non-comminutable object has been transported between the two comminuting rollers 13, the spring device 42 moves the 8/15 Austrian Patent Office AT 13 526 U1 2014-02-15

Side moving crushing roller 13 automatically returns to the rest or working position and the crushing device 1 is ready for use again.

To ensure easy cleaning and thus a hygienic operation of the crushing device 1, it is expedient to perform bearings 43 of the axes of rotation 29 of the crushing rollers 13 so that a simple disassembly of the crushing rollers 13 is preferably possible without tools. Furthermore, it is expedient in this context to perform the crushing rollers 13 dishwasher safe.

For the sake of the order, it should finally be pointed out that, for a better understanding of the structure of the comminution device, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

All information on ranges of values in the present description should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all sub-areas begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

The problem underlying the independent inventive solutions can be taken from the description.
