EP0842873B1 - Spraying device on a refuse vehicle for disinfecting the refuse and the refuse receptacle - Google Patents

Description

The invention relates to a device for or on a waste, in particular a so-called bio-garbage picking up and transporting motor vehicle in which the the garbage bin by means of swivel arrangements provided at the end of the train tilted up to empty and after emptying back into the Starting position is pivoted back to spray the from the bin into the recording room the garbage to be thrown away and the emptied bin with one disinfectant that treats the garbage and cleans the bin.

In the separation of households and commercial enterprises, which has been practiced for some time arising waste in each case to be collected and then further recycling types of waste (paper, plastics, etc.) will also be a separate collection of perishable organic substances, especially food residues, in separate Containers made. Such waste is caused by bacteria decomposes and is later to be used for composting in gardens etc. be used. One therefore has the expression for this "Organic waste" shaped. A major disadvantage of this Organic waste consists of being in its collection containers - also called "organic tons" - to a large extent harmful to health Form molds. The hereby arising Aspergillus spores can be life-threatening for allergy sufferers his. The staff of the Garbage disposal, which when emptying the bio-bins becomes toxic Can breathe spores. Children and people are also with weakened immune system particularly at risk.

To the explained disadvantages of garbage, especially one So-called organic waste, at least partially to eliminate it known in the garbage truck above the recording room for to provide the garbage or bio-garbage with a spray device, which sprinkles the garbage with a liquid, which is disinfectant (see for example DE-PS 74 686, DE-PS 81 195, DE-PS 112 628 and DE-GM 94 03 313.7). If it is organic waste it can be said that spray Can be used, which is the quality of the organic waste do not interfere. At the same time as the disinfection mentioned above there will also be an annoying smell of the part garbage or organic waste in progress or at least diminished.

With these known spray devices, however, only the already dropped into the receiving area of the garbage truck Treated garbage; but not with the garbage leftovers, the one on the inner wall and the bottom of the barrel stick to their emptying. If not by users of these tons for cleaning the ton or a Spraying the barrel with such an agent the Aspergillus spores remain in the Ton stick, multiply and continue to provide one represents a potential danger for every person who Introducing new organic waste opens. The same threat applies to the people of the garbage disposal who the tons handle and lead the garbage truck to its emptying, because with the tipping of the barrels into the drop position their lids open automatically and the existing ones Aspergillus spores are thus distributed in the environment can. Experience now shows that for convenience or Forgetfulness the above Clean or disinfect the emptied organic tons is omitted. It is known (see e.g. DE-PS 938 299 and DE-PS 2 056 039), spray devices for disinfecting the empty garbage cans provided. But these orders are also incomplete, since no spraying and disinfection of the garbage emptied from the garbage cans.

Finally, it is known from DE-AS 10 24 875 by means of one and only adjustable in one spray direction Spray nozzle first the garbage falling out of the bin spray with a disinfectant and then the barrel interior and the barrel lid also with this Spray disinfectant and disinfect it. This has several disadvantages. It is only on the Area of garbage sprayed after it fell in the recording room at the bottom. That leaves the upper one Layer of garbage unsprayed. This leads to the above explained disadvantageous odor formation and possibly also the formation of mold. You can also use a single setting of the spray direction is not optimal both the falling garbage and the inside of the barrel to reach. The latter is especially true when using the same garbage truck tons of different internal cross-section and length should be emptied and sprayed.

From DE 42 16 347 A1 a garbage collection and garbage container cleaning vehicle is included a garbage collector and a loader for the garbage bins as well as with one Known cleaning device for cleaning the garbage containers. The cleaning device comprises a arranged in the garbage container of the vehicle and on one Nozzle arm fixed nozzle head for injecting disinfectant into the emptied Garbage container. The nozzle arm is on the rear wall of the waste collection container above arranged the loading opening and pivotally mounted about a pivot axis. In a substantially parallel to the ceiling of the garbage collector Position of the nozzle arm is the nozzle head in a rest position, so not in Business. From this rest position, the swivel arm with the nozzle head down pivoted so that the nozzle head points into the waste container and thereby the disinfectant can spray into the garbage can. The nozzle head is exclusive used to spray the waste container with disinfectant. It becomes explicit indicated that the garbage already stored in the garbage collection bin is not compatible with the Disinfectant should be contaminated so that its compostability is not A swiveling of the nozzle head relative to the nozzle arm is also not disclosed.

Compared to this state of the art, there is the task or problem of Invention flawlessly both with a relatively low design effort to disinfect the discarded garbage as well as the garbage can.

To solve this task or problem is starting out from the preamble of the claim 1, according to its characteristics initially provided that the Spray device has a spray nozzle carried by a pivotable pivoting device and pivotable to the pivoting device and fixable in the respective pivoting position, which consists of a first spray position for spraying in the direction of the garbage in the Recording space in a second spray direction of a second Spray position can be brought in which the respective spray jet into the interior of the one in its emptying tilt position Ton is directed and that a control is provided the first named after the bin has been emptied Initiates spraying of the garbage, as well as after and before The spray nozzle swivels back into its starting position brings in the second spray position and the spraying of the Inside the emptied bin. If above in the singular "ton" is spoken, but this excludes also the version common to most garbage trucks with two side by side on the rear of the garbage truck attachable and each can be emptied (see see also claim 13).

With the interaction of the features of claim 1 on the one hand it is ensured that the bin is emptied is sprayed on the inside with the disinfectant, so that garbage remains still present, including Aspergillus spores be destroyed or removed and the front especially in hot weather very unpleasant stench of Garbage, especially organic waste, at least reduced without this becoming an activity of the belonging to the respective household or business and with the care of the garbage bins required persons. Secondly, the same spraying device is advantageously used for this used, which the disinfectant on the throws garbage thrown into the receiving space of the vehicle. This will reduce the cost of a second separate spray device and the space they cause is avoided. It is particularly advantageous that the above mentioned Spray positions or spray directions of the spray nozzle or Spray nozzles when passing garbage cans of a certain Design on other garbage cans with a different cross-section or length in the second spray direction correspondingly without problems can adjust.

1, 2 show parts of a garbage truck 1 with a rear wall 2 and a dash-dotted rear wheel 3. The front area of the garbage truck, which is not of interest here lies in the direction of arrow 4, which is also the Shows the direction of travel.

The bio-tons to be emptied are 5 in also known manner placed on a swivel assembly and from their dash-dotted position 5 'in Fig. 2 around the Swivel axis 6 up to the emptying position 5 " tilted. In this position, the lid 5 '"comes into the Open position and the organic waste falls in the direction of the arrow 7 in the receiving space 8 of the garbage truck. At 9 they are Numbered castors of the organic tons.

1 and 2 show an even closer with reference to FIG. 3 - 8 to be explained spray device 10 with its two end positions the first spray position 10 '(with solid lines) and the second spray position 10 '' (with dashed lines). In the spray position 10 ', it sprays in the direction 11 on the one located in the recording room 8, indicated by number 12 dumped organic garbage. In the second spray position 10 '' is in the direction 14 in the interior 14 of the Bio-tons 5 sprayed in such a way that both the inner walls as well as the bottom of the barrel reached by the spray become. The timing of these spraying processes and their Control is explained in more detail with reference to FIG. 10. The nozzles 22 of the spray devices 10 are so-called two-substance nozzles, into which both air is pressed and the spray is entered so that air and spray together as Exit spray mist. This is also based on the detailed explanation the supply of the liquid for disinfection with reference to FIGS. 11-15.

The spray devices 10 can be on a basic or Support plate 15 may be attached to the rear wall 2 of the Garbage truck attached, preferably detachably screwed. There is a pneumatic or on this support plate Hydraulically operated lifting cylinder 16 with lifting plunger 17. Furthermore, there is an elbow that is angled out of the two Arms 18, 19 is, articulated at 20 and thus pivotable articulated to the base plate 15 on this. According to Figures 3 and 4 grips one angle arm 19 at an articulation point, here a bore 21 of the lifter 17. To change the The plunger can also translate the swivel movement attack one of the adjacent holes 21 'and 21' '. The other angle arm 18 carries the spray nozzle 22. About the lifter 17, the elbow is either in the first spray position according to para. 10 '(with solid Lines shown in Fig. 3) can be brought. In this position the lifting plunger 17 is drawn into the lifting cylinder 16. 3 shows the position of the spraying device in dashed lines in the second spray position 10 '' with the solid Lines is shown in Fig. 4. To achieve this Position, the ram 17 is pushed out of the lifting cylinder 16. Fig. 4 also shows the dash-dotted lines Position of the angle arms 18, 19 in their positions 10 '.

It can be seen that in the first spray position according to Position 10 'in Fig. 3 of the spray 11 on the thrown Rubbish 12 sprays; however, in the second spray position according to position 10 "according to spray 13 into the barrel interior. The hydraulic or pneumatic medium is included Inlets and outlets 23, 23 'fed to the lifting cylinder 16. In the angle arm 18 carrying the spray device 10 are located lines 24 for the agent to be sprayed and 24 'for the compressed air. The attachment 15 of the spray devices are between the respective barrel 5 and associated outer wall 2 '.

In the emptying position 5 "of the garbage can 5 (see in particular Fig. 2) can cover 5 '"around its articulation 59th commute back and forth according to the double arrow 60. there can the lid in the swivel path of the spray nozzle 22 and they support angle arm 18 from the first spray position 10 '(see FIG. 2) in the second spray position 10 "in The swivel path of the spray nozzle. But this would be the hinder the aforementioned pivoting, causing damage of the aforementioned parts can result. To avoid this is on the rear wall of the receiving space 8 a compressed air spray nozzle 61 is provided, in such a way that the air jet 62 emanating from it against the cover 5 '", preferably blows its free end 63. The compressed air spray nozzle 61 is turned on by the controller when the first spraying is over. The airflow 62 of the then switched on air pressure spray nozzle holds the lid 5 '" in a position in which it is shown in FIG Location is slightly pivoted to the outside. Then the spray nozzle 22 pivoted freely into the second spray position 13 become. If the second spray 13, i.e. cleaning of the barrel interior, was carried out and the spray nozzle returned to the first position (see Fig. 2) is then the compressed air supply to the compressed air spray nozzle 61 switched off again.

As FIG. 1 also shows, it is a preferred embodiment the invention that both on the driver side (in the Rule Fig. 1 right half), as well as on the passenger side (usually Fig. 1 left half) such a spray device including the means to operate them located, so that two tons of 5 and that of garbage thrown at them can be sprayed.

Depending on the spatial arrangement and location of the upturned Tons, the receiving space and the aforementioned parts of the Spraying device and its actuations may be necessary be the spray nozzle 22 to the parts of it carrying Spray device 10 in the first spray position another To give position than in the second spray position. This is 5, the spray nozzle 22 with its housing 22 'by one Bearing pin 25 rotatable, which on the angle arm 18 Spray device 10 is located. Furthermore, one with the spray nozzle 22 counter-stop 28 which can be pivoted together (see 6 and 7) are provided, in the swivel path an abutment 27 is a stop plate 26, the the inside of the vehicle housing thus firmly connected is. The counter stop 28 is connected to the spray nozzle housing 22 ' firmly connected. It can also be used with the spray nozzle housing be in one piece. If the respective spray device 10 in the first spray position according to FIG. 3 pivoted to the right, see above the counter stop 28 comes to the stop plate 26 Investment. The stop plate 26 is relative in the direction 26 ' displaceable to the abutment 27 and thus to the vehicle housing and ascertainable. For example, this can be done by two slots 26 "of the stop plate 26 happen are penetrated by locking screws. The further the stop plate 26 to the left in Fig. 3, i.e. contrary to Swinging direction of the spray nozzle is shifted, the stronger is after the start of touching the counter stop 28 on Stop plate 26, the spray nozzle housing 22 'against the direction of the arrow 53 (see Fig. 6) pivoted about the bearing pin 25 and against the action of a spring 54. This setting the displacement position of the stop plate 26 to the abutment 27 needs only once at the start of commissioning the concerned Be made vehicle. The same applies the setting of the adjusting screw 30 explained below.

The bearing pin 25 is mounted in a holding bracket 55. This bracket can be to the angle arm 18 about the longitudinal axis a set screw 56 can be rotated, the set Location can be fixed by a nut 57 (Fig. 5). Fig. 7 shows that the spring 54 as a spiral spring around the bearing pin 25 is wound, with both spring arms striving are to be separated. One spring arm is on Counter stop 28 and the other spring arm on the bottom surface of the bracket 55. This is due to the position of the stop plate 26 and any pivoting required of the bracket 55 around the screw 56 the desired spray direction 11 of the nozzle 22 in this first spray position the discarded waste 8 set in the receiving space 12 (Fig. 3).

With the pivoting of the spray device 10 in the second Spray position 10 "(dashed lines in Fig. 1 and Fig. 3) the counter stop 28 from its stop position with the Stop plate 26 pivoted away. Thus, the spring 54 can Spray nozzle housing 22 'with the spray nozzle 22 so far in FIG. 7 pivot counterclockwise around the bearing pin 25, until the bottom of the housing 22 'or that in Fig. 7 above located end 28 'of the counter-stop 28 for contact with the free end 29 'of an adjusting screw 29 arrives. The Position of this free end 29 'by adjusting the Screw 29 by means of its screw head 30 in its longitudinal direction 30 can be changed. It's through a lock nut 58 noticeable. So that can by the aforementioned Screw setting 29/30/58 in the second spray position 10 " the spray direction of the nozzle 22 and thus its spray jet 13 be adjusted so that this spray jet inside the barrel is directed and even the inner walls of the Ton and also sprayed their bottom.

Fig. 10 shows schematically the corresponding to the elbows 18 Swivel devices with the same numbering the spray nozzles 22 and their spray jets 11 for spraying of garbage 12 in the receiving room 8. This spraying is initiated, after the one dropped from the dumped barrel Garbage from radar pulses 30 emitted by a transmitter 29 went through. Then, in detail hydraulic or hydraulic control, not shown pneumatic valves 31 opened by the pneumatic Pressure source 32 forth the supply of compressed air and from the Liquid source 33 forth the supply of the to be sprayed Release liquid to the nozzles 22. The associated Lines are for the compressed air with 32 'and for the liquid numbered 33 '. The duration of spraying the discarded garbage mass 8 is adjustable. Then the Control a closing of the valves 31. Thereupon further pneumatically or hydraulically operated valves 35 opened, which the pressure medium to the respective lifting cylinder 16 feed and in such a way that the pivoting device 18 from the solid in Fig. 10 Lines drawn position rotated by 90 ° and the dashed Occupies position 18 '. Then the spray nozzles a position in which they spray into the barrel in accordance with paragraph 13 (See also explanation of FIG. 1). Subsequently the control causes the valves 31 to open, specifically preferably after a set time. So they are sprayed empty barrels from the inside, the valves 31 closed and the control system causes it to swing down of the tons from position 5 according to FIG. 2 into position 5 '. At the same time, the spray devices are in position 18 of Fig. 10 pivoted back.

So it is with one and the same spray device and there the spraying of the thrown off can be controlled in succession Garbage as well as the spraying of the barrel attainable.

Fig. 10 shows in the lower half that of the staff actuating device, namely a hand lever 36 around the Swiveling the barrels 5 up into the upper layer 5 according to FIG. 2 and pivoting them back into the lower layer 5 'of FIG. 2 to enable. But it must be prevented that the operator concerned swiveling back too early initiates and thus the spraying of the barrel completely or partially prevented. Pressure switches 38 are provided for this purpose, by operating the control lever on "lifting", a gear pump 39 switches on for the liquid to be sprayed so that it after opening the valves 31 via the lines 34 to the Spray nozzles arrives. As soon as the radar pulses 30 are addressed have, i.e. the tons are in the upturned position and the garbage has been discarded, a hydraulic Solenoid valve 40 switched on, creating a line connection 41 from a hydraulic pump 42 to hydraulic lifting cylinders 37 is closed. As long as these cylinders with their lifters 37 'under the hydraulic pressure of the pump 42 stand, they keep the tons in the upturned position. is also the second spraying process and the corresponding on the timer 43 set time has expired, the swivel levers 18 from position 18 'to their vertical, with solid lines Lines shown position pivoted. At the same time a control of the solenoid valve 40 in such a way that the Line connection 41 is interrupted there. Hereby will the pressure in the hydraulic lifting cylinder 37 is reduced and their Lifting plunger 37 'can under the weight of the concerned Ton go back into the lifting cylinder 37, with which the concerned Ton position 5 '(Fig. 2) can assume.

10 on the right and FIGS. 11-14 show in common Housing 44 is an arrangement of two containers 45, 46 for the liquid to be sprayed and the gear pump 39. One of the two containers 45, 46 is provided as a reserve, while the other container has a connection 47 for the Aspirating the spray liquid contained in it. On a separate, preferred inside the container centrally provided tube 48, a float 49 is attached, which slid in the vertical direction and from is visible from the outside, so that the operator in each case can see how much spray liquid is left in the container is available. 15 shows a variant in which the suction pipe 50 leading to the connection 47 and the guide 51 for the float 49 are inserted into each other.

Instead of making the float 49 visible, you can also do so proceed that a reed contact in the lower area of the arrangement 52 is provided, of which the lower area reaching float 49 is actuated and a display signal actuated.

All features shown and their combinations with each other are essential to the invention.
