Definitions
- Such devices for shredding are known as large-volume shredding machines with powerful drives for the shredding rotor and are used, for example, in the wood industry or waste management.
- a shredding machine in which a slide is displaceable over a cylindrically curved base and presses the material to be shredded against the rotor
- Such a crushing device is also from JPH08290075 A known.
- a shredding machine is also disclosed with a feed wall fixedly mounted in a housing, the upper edge of which adjoins a loading window on the housing.
- the feed wall is inclined in such a way that material to be comminuted that is fed through the feed window slides down on its surface.
- the material to be shredded is fed to a pusher which presses it against the circumferential surface of a shredding rotor.
- the object of the invention is to create a comminuting device which is more flexible with regard to the supply of the material to be comminuted.
- the inventors have recognized that, in particular in the case of smaller shredding machines designed for drive motors with lower rated powers, a better metering of the material supply is necessary compared to the previous supply methods. Otherwise too much material gets between the knives and the counter knives at once, which increases the power consumption of the drive motor of the shredding rotor. In addition, with smaller shredding machines there is an increased risk that the shredding rotor will block if too much material is fed in at once.
- the shredding machine is a shredding machine with which medical waste is to be shredded in hospitals in the immediate vicinity of patient rooms and operating areas. Because there is generally only a 230 volt single-phase power supply available so that the maximum power of the drive motor is around 3.5 kW. Alternatively, the device according to the invention can also be supplied with 400 V and have a drive power of 5.5 kW. Both pure electric motors and hydraulic motors are conceivable as drive motors. Further areas of application which come into consideration for the device according to the invention are, for example, the chopping up of leftover food or information carriers (paper files, electronic data carriers, etc.).
- the invention is based on the knowledge that when the feed plate of a shredding device is rotatably mounted and its position can be controlled, it can take over several functions within the shredding device.
- the feed plate can be used as a chute with a variable pitch, whereby the material feed can be controlled in the direction of the shredding rotor.
- the feed plate can be used as a presser so that the material to be shredded can be grasped by the shredding rotor as quickly as possible. In this way, by integrating both functions in a single component, a cost-effective construction and operation of the device can be achieved.
- the feed plate can be swiveled over its swivel axis with respect to the shredding rotor.
- feed plate should not necessarily be understood to mean a plane-parallel plate. Rather, it is a component that has at least one main surface on which the material to be shredded can slide in the direction of the shredding rotor.
- the geometry of the feed plate can also be adapted to the circumference of the shredding rotor.
- the axis of rotation of the shredding rotor and the pivot axis of the feed plate will be arranged parallel to one another.
- the slope of the first main surface of the feed plate relative to the horizontal can be varied at least in the range of approximately 15 ° to 25 °, preferably 10 ° to 45 °, again preferably 5 ° to 85 °.
- the feed rate with which the material to be shredded is fed to the shredding rotor can be controlled in a simple manner, steplessly and as required.
- the supply of material to the shredding rotor can be stopped completely.
- the shredding rotor can be operated in both directions of rotation.
- the axis of rotation of the shredding rotor and the pivot axis of the feed plate define a plane that divides the device into two sub-areas and that the first counter-knife is located in the first sub-area and a second counter-knife is located in the second sub-area.
- the plane forms an acute angle with the Vertical closes.
- the asymmetrical geometry of the cutting space results in a different cutting behavior of the device in the two directions of rotation.
- the feed plate is rotatably mounted at one end about the pivot axis. This results in a greater effective length of the main surface of the feed plate with which it presses the material to be shredded against the shredding rotor. In this way, in the plane of the feed plate, the greatest possible passage space for the medical waste material is created between the pivot axis and the housing of the device.
- such a passage space can also be advantageous between the pivot axis and the surface of the shredding rotor.
- the axis of rotation of the shredding rotor and the pivot axis of the feed plate are spaced from one another in such a way that when the direction of rotation of the shredding rotor changes, the material to be shredded can be fed to the second counter knife.
- the material to be shredded passes through the created passage space into the second sub-area of the device.
- the feed plate can also be expedient for the feed plate to be brought into an intermediate position so that it forms a kind of funnel together with the shredding rotor, which guides the material to be shredded.
- the feed plate is in a second pressing position can be brought about, in which the material to be shredded is pressed against the shredding rotor with a second main surface of the feed plate and is shredded between the knife and the second counter knife.
- the feed plate is rotated about its pivot axis in the opposite direction.
- the feed plate can thus be used like a kind of "flipper" to press on when the shredding rotor rotates in one or the other direction of rotation.
- a different cutting geometry can be provided on the second counter knife than on the first counter knife, in particular because the second counter knife is not arranged radially to the shredding rotor.
- the feed plate has a swivel range of at least 200 °, in particular of at least 270 °, about the swivel axis.
- a large pivoting range of the feed plate is accompanied by a large distance between the pivot axis and the shredding rotor.
- a large circumferential area of the shredding rotor can be used.
- due to the larger volume between the feed plate and the comminuting rotor due to the larger volume between the feed plate and the comminuting rotor, a larger amount of material to be comminuted can be fed to the device at once.
- a control device which the actuator of the feed plate and controls the shredding rotor in such a way that the power consumption of the shredding rotor does not exceed the maximum power specification.
- the control device can vary the slope of the main surface of the feed plate depending on the power consumption of the drive motor of the shredding rotor in the feed position and / or vary the contact pressure of the material on the shredding rotor in the pressure position by setting different angular positions.
- the control device can also change the direction of rotation of the shredding rotor and its setpoint speed and thereby pivot the feed plate into the second pressure position.
- 10 denotes a device as a whole, with which material, here medical waste material 12, can be comminuted.
- the device 10 makes it possible in hospitals not to convey medical waste by cleaning staff via corridors and elevators to a collection room in the basement, as was previously the case, but to shred it on site.
- the shredded material can then be transported to the basement via an existing sewer system, where a sewage treatment plant removes the material from the wastewater and prepares it for final disposal. This significantly reduces the germ load in hospitals.
- the device 10 has a housing 14 with a feed opening 16 which can be closed with a lockable flap 17. This allows easy loading from the front or of the page.
- a displaceable door (not specifically shown) can alternatively be provided, which can be displaced, for example, between an open and a closed position.
- an operator protection device in the form of a collecting plate 18, a pivotable feed plate 20 and a shredding rotor 22 are arranged, the axis of rotation 30 of which is arranged perpendicular to the plane of the drawing of the figures.
- the feed opening 16 is shown here to the side with respect to the axis of rotation 30 of the shredding rotor 22, depending on the spatial requirements, it can also be arranged on a side of the housing 14 that is perpendicular to the shredding rotor 22.
- the shredding rotor 22 has a substantially cylindrical shape and is only supported by one in Figure 1 drive motor 23 shown schematically.
- the shredding rotor 22 carries knives 32 which protrude in the radial direction. These work together with a first counter knife 24, which here is arranged horizontally a little below the axis of rotation 30 on the circumference of the shredding rotor 22 and thus essentially radially to the axis of rotation 30 of the shredding rotor 22.
- a second counter knife 26 is offset by approximately 160 ° with respect to the circumference, ie here also arranged horizontally somewhat above the axis of rotation 30, so that the second counter knife 26 is not aligned radially to the axis of rotation 30.
- the shredding rotor 22 is delimited in a lower circumferential area between the first counter knife 24 and the second counter knife 26 by a perforated screen 28, which is radially spaced from the shredding rotor 22 and with this forms a circumferential gap in which the knives 32 are still between the shredding rotor 22 and perforated screen 28 can walk through it.
- the medical waste material 12 can be fed to the shredding rotor 22 in the upper, free circumferential area between the counter knives 24, 26.
- the knives 32 When they rotate about the axis of rotation 30, the knives 32 are in engagement with the first counter knife 24 and the second counter knife 26 and comminute the medical waste material 12 supplied in such a way that it can fall through the perforated screen 28.
- the feed plate 20 is arranged above the shredding rotor 22.
- the feed plate 20 has a first main surface 34 and a second main surface 36 and is mounted rotatably about a pivot axis 38 running essentially parallel to the main surfaces 34 and 36.
- the pivot axis 38 is also arranged essentially parallel to the axis of rotation 30 of the shredding rotor 22.
- the feed plate 20 is effective in a manner not shown with a likewise only in Figure 1
- the actuator 25 shown is connected, with the aid of which the angular position of the feed plate 20 about the pivot axis 38 can be varied.
- the swivel range 21 (cf. Figure 2 ) of the feed plate 20 covers at least 200 ° above the shredding rotor 22.
- Both the drive motor 23 and the actuator 25 are connected to a control device 27 which initiates the different operating modes.
- a two-part collecting device 40 which comprises two collecting flaps 42, such as the one Figures 7 and 8 demonstrate.
- the collecting plate 18 of the operator protection device is arranged between the feed opening 16 and the feed plate 20 and locked in an essentially horizontal position in which the collecting plate 18 extends essentially to the housing walls and thus covers the shredding rotor 22.
- a safety circuit ensures that the lockable flap 17 at the feed opening 16 of the device 10 can only be opened when the collecting plate 18 is in this overlapping position.
- the collecting plate 18 thus prevents intervention by the operating personnel and at the same time serves as a support for the medical waste material 12 fed through the feed opening 16 of the device 10.
- the collecting plate 18 which is not provided in previously known shredding machines, makes it possible to dispense with providing a circumferential protective wall above the shredding rotor 22.
- Conventional shredding machines must therefore are always filled from above and build tall, so they can only be used in factory buildings. The use of the collecting plate 18 thus allows it to be used in normal rooms such as, for example, in hospital rooms.
- the Figure 1 illustrates a first embodiment of the device 10 in a rest position. Medical waste material 12 was fed into the device through feed opening 16. This lies on the collecting plate 18, which in the present exemplary embodiment is mounted horizontally above the feed plate 20.
- the collecting plate 18 is brought into a vertical storage position with a pivoting movement, in which it remains during the comminution process. In doing so, the medical waste material 12 falls as in FIG Figure 2 shown on the first major surface 34 of the feed plate 20.
- the shredding rotor 22 is then set in rotation (in Figure 2 clockwise).
- the feed plate 20 is gradually rotated clockwise from its horizontal rest position about the pivot axis 38.
- the collecting plate 18 has reached its storage position, the medical waste material 12 slides along the first main surface 34 and is fed to the shredding rotor 22 as required.
- the medical waste material 12 comes into contact with the knives 32 of the shredding rotor 22, is taken along and cut into smaller pieces at the first counter knife 24 at the latest. Once the smaller pieces have reached a certain minimum size, they can fall through the perforated screen 28 and be disposed of.
- the control device 27 monitors the speed and power consumption of the drive motor 23 and ensures that the slope of the feed plate 20 is adjusted accordingly in order to prevent excessive power consumption or blocking of the shredding rotor 22.
- a further metering functionality of the feed plate 20 can also be achieved in that the waste material 12 to be shredded is specifically clamped between the housing 14 and the feed plate 20, as is the case with FIG Figure 3 shows. This can be particularly relevant when the waste material 12 is supplied in sacks or the like.
- the feed plate 20 starting from the horizontal rest position, is pivoted in such a way that the waste material 12 to be shredded rests on the shredding rotor 22.
- the waste material 12 or the sack in which it is located, is between the feed plate 12 and a housing wall - or as in FIG Figure 3 -
- the collecting plate 18 is clamped.
- the material 12 can be pressed against the shredding rotor 22. If an increased power consumption is determined, the pressing force is reduced or removed.
- the Figure 4 illustrates how the feed plate 20 is used as a pressing device for this purpose.
- the control device 27 first swivels the feed plate 20 from the feed position, in which the waste material 12 rests essentially on the first main surface 34, into the first pressing position, in which the feed plate 20 with the first main surface 34 in the Figure 4 presses on the waste material 12 essentially from above.
- the feed plate 20 exerts a pressure force on the medical waste material 12, which is directed essentially in the direction perpendicular to the first main surface 34.
- the supply of the medical waste material 12 is further facilitated by the fact that the housing 14 has curved walls in the vicinity of the shredding rotor 22, these walls running out essentially radially to the shredding rotor.
- the present exemplary embodiment also provides that the comminution rotor 22 is operated in both directions. This is in Figure 5 shown, in which the shredding rotor 22 is shown running counterclockwise.
- the knives 32 on the shredding rotor 22 are double-edged for this purpose.
- the pivot axis 38 and the axis of rotation 30 form a plane that divides the housing into two sub-areas divides.
- the shredding rotor 22 is arranged eccentrically on the housing 14, so that the plane formed by the pivot axis 38 and the rotation axis 30 forms an angle ⁇ with the vertical.
- This enables the device 10 to be constructed asymmetrically with respect to the plane, as a result of which the two partial areas are designed to be geometrically unequal.
- a different intake behavior of the waste material 12 in relation to the respective housing wall and counter knife 24, 26 is generated, which can contribute to more efficient comminution.
- the pivot axis 38 of the feed plate 20 and the axis of rotation 30 of the shredding rotor 22 are at a distance that is greater than the radius of the shredding rotor 22, a passage space is created between the cylindrical shredding rotor 22 and the pivot axis 38.
- the medical waste material 12 will then be taken along by the shredding rotor 22 and fed to the second counter knife 26 through the passage space. If the pressing force of the feed plate 20 is removed and the feed plate 20 is pivoted in a counterclockwise direction and locked in an intermediate position, the feed plate 20 together with the surface of the shredding rotor 22 forms a funnel.
- the medical waste material 12 slides along the first main surface 34 of the feed plate 20.
- the funnel function can also be achieved by simply removing the pressing force in the first pressing position of the feed plate 20, without locking in a defined intermediate position being necessary.
- the feed plate 20 is pivoted in the counterclockwise direction so far that it can press against the medical waste material 12 with its second main surface 36, as shown in FIG Figure 6 shows.
- the pressing force here acts perpendicular to the second main surface 36 of the feed plate 20.
- the forces acting on the medical waste material 12 can lead to an undesired compression of the medical waste material 12 during operation.
- a further reversal of the direction of rotation of the shredding rotor 22 is provided in a further step.
- the feed plate 20 again acts together with the surface of the shredding rotor 22 like a funnel, the second main surface 36 serving here as a guide element for the medical waste material 12.
- the medical waste material 12 is transferred again from the second sub-area into the first sub-area of the device 10.
- the feed plate 20 is brought into its first contact position.
- Control device 27 can be determined, for example, by a load torque increase on drive motor 23 of shredding rotor 22. Such an increase in load torque may indicate compaction of the medical waste material 12.
- the operator protection device is as shown in FIGS Figures 7 and 8 shown, formed from two collecting flaps 40, 42 arranged horizontally in their rest position.
- the collecting flaps 40, 42 are pivotably mounted on a common axis 44 which runs essentially parallel to the axis of rotation 30 and the pivot axis 38.
- the distance between the axis 44 and the pivot axis 38 is at least as large as the length of the feed plate 20, so that it can be pivoted between its first pressing position and its second pressing position without hindrance.
- a collecting flap 42 is opened by pivoting it downward. If the collecting flap 42 has been pivoted further and removed from the pivoting range of the feed plate 20, the medical waste material 12 can be fed to the shredding rotor 22, as shown in FIG.
- the open collecting flap 42 can be pivoted back into its rest position.
- the fall arrest device can also fulfill its safety function during operation.
- a collecting plate 18 or collecting flaps 40, 42 can be dispensed with. So that an operator protection function is nevertheless ensured, the open position of the lockable flap 17 can only be reached in this case when the shredding rotor 22 is not moving.
- electrical and / or mechanical monitoring devices can be provided which, in combination with the lockable flap 17, form the operator protection device.
- material is preferably supplied during operation when the supply plate 20 is in its supply position. This enables the medical waste material 12 to be comminuted to be metered.
- the device 10 can have an intermediate ceiling 50 above the opening 16.
- nozzles 52 are arranged with which disinfectant and cleaning water can be sprayed into the device 10. In this way, the device 10 can be disinfected and rinsed out from time to time.
- a camera 54 can be arranged in the false ceiling 50, which camera documents the destruction of a specific information carrier.
- the feed plate 20 is provided with pressure wedges 56 and 58 on both sides at its end remote from the pivot axis 38.
- the Pressure wedges 56 and 58 make it possible to bring the surface of the feed plate 20 that is effective when it is pressed closer to the cylindrical comminuting rotor 22.
