WASTE WASTE RECOVERY AND PROCEDURE FOR WASTE COLLECTION

BACKGROUND OF THE INVENTION The present invention relates to a waste collection carriage comprising a removable container as well as one at the end surface of the container and in proportion ten. The container is rearwardly displaceable rearwardly, which rearwardly mounted at the opposite end of the cab position and comprises a primer for compressing waste, as well as a method for collecting waste.

10 German Patent Specification No. 2,817,599 discloses a waste carriage for the transport of removable containers, which are only suitable for placing the containers in designated places where garbage is loaded, either manually or mechanically. Furthermore, the actual emptying of the containers will require a collection truck specially designed to receive the waste from the containers.

German Patent Specification No. 2,407,615 discloses a waste collection truck for collection of waste and equipped with a container and a back piece in which the waste is loaded before it is transferred to the container. However, the system has the disadvantage that the back piece is hinged at the top, which is why this must be lifted upwards when removing the container, which constitutes a space and resource demanding maneuver. On the other hand, the waste trolley does not include standalone lifting devices, so it is necessary to use an external lifting device when removing the container. This is heavy and inconvenient as well as consuming resources. In addition, the hinge of the tailgate makes lifting devices impossible as an integral part of the carriage.

25

From EP A1 364 835 is known a refuse truck equipped with a container and rear piece. The back cover is attached to the bottom of the car frame. The tailgate is designed so thin that it is possible, after the tailgate is tilted into a horizontal position, to drive the carriage away from the filled container placed on the support part. Thus, the thickness of the rear panel is determined by the height of the wheels, so the rear panel may not be as thick as desired. One result of this is that the filling of waste in the container takes place relatively slowly due to the small chamber.

WO A1 95/00357 discloses a system for lifting containers from a wagon. Part 5 requires the system to have support surfaces so that the lifting device can be used, and secondly, there is no suggestion that such a lifting device can be mounted on waste trucks. The construction is thus very demanding and does not allow for the treatment of the waste.

10 From German patent specification DE A1 43 31 750 there is known a refuse truck, which is equipped with a container and a rear slidable slider. The back compactor is shaped like two plates that push the waste from the back into the container. This type of compaction has the disadvantage that during the compaction of the waste from the backing into the container there is a great risk of this falling out 15, since there is no smooth flow of the waste. In addition, it is necessary to divide the back piece into two pieces that are moved to each side to allow removal of the container from the drawer. In this way, the wagon takes up a disproportionate amount of space, taking up not only additional space in terms of longitudinal conditions, namely the length of the tailgate, but also in the width direction of the carriage corresponding to half the width of the tailgate.

The object of the invention is to provide a waste carriage which does not have the disadvantage of the known systems and which enables a handy collection of waste, since the waste can be emptied directly into the rear of the waste carriage and on to the container, after which the filled containers are easily and effortlessly can be removed from the carriage laterally and placed where it is desirable without the use of external auxiliary means by means of the integrated lifting arms, or emptied laterally directly into a collection container. Precisely this lateral movement of the filled container is a great advantage as it allows for a more flexible emptying of the container and that the refuse truck has access to places where the known carts normally do not move.

3 DK 173433 B1

In addition, the construction enables larger refuse collection trucks to subsequently empty the filled containers into their large collection containers. In this way, the collection of waste is rationalized, since according to the invention flexible waste trucks are replaced by the otherwise known large and heavy re-wagon cars, which travel around with half-filled containers for a further further collection of waste.

The object is achieved by a refurbishment truck of the one stated in the preamble, and where preferably at the front and rear of the container are mounted lifting arms for side-10 host removal of the container, which lifting arms form an integral part of the refuse wagon and that the compactor is an inclined auger. in a cylindrical tube, said tube comprising an opening at the top for passage of debris into the auger and the other end of the auger extending through a recess / opening at one end of the container when the back piece is in operative position.

15

The waste is loaded into the back piece, from where it is compressed into the container itself.

When this is filled, the compactor is pushed backwards with the compactor and the lifting arms allow a lateral lifting of the container, which is thus emptied or put down, after which an empty container is mounted on the load.

20

By designing the cleaning trolley according to the invention as claimed in claim 2, it is achieved that the rear panel can be effortlessly and unambiguously slid backwards, leaving room for the operation of the lifting arm.

By designing the waste trolley according to the invention as claimed in claim 3, a simple way of removing the container is achieved.

By designing the waste trolley according to the invention as claimed in claim 4, a secure and adjustable grip of the containers during movement is possible, with the gripper claws 30 gripping around the buds arranged thereon.

4 DK 173433 B1

By designing the waste trolley according to the invention as set out in claims 5 and 6, it is achieved that the lifting arms can operate as soon as the rear part is displaced, partly creating pads for this function, which causes the movement of the rear part that the container is now removable.

5

By designing the waste trolley according to the invention as claimed in claim 7, an appropriate handling of the waste is achieved.

By designing a waste carriage according to the invention and as further stated in claim 8, it is achieved that the risk of waste falling out when the tailgate is pushed back is minimized.

By designing the cleaning trolley according to the invention as claimed in claims 9 and 10, it is achieved that by using a protruding part of the lifting device which influences the pressure pad in the recess, the lock is activated via the connecting elements and the lid can thus be opened at the same time. with the recess providing a stable grip for the operation of the lifting device.

The invention also relates to a process for the collection of waste and the like in 20 containers by means of the aforementioned waste carts, characterized in that the waste is loaded into the back of the container, that the waste is subsequently transferred into the container via an opening formed in this container. container is subsequently lifted beyond the longitudinal side of the chassis frame of the wastewater by means of lifting arms which form an integral part of the wastewater, which container is emptied into a collection container or placed thereon, preferably in a collection station, which lifting arm of the wastewater subsequently lifts the same or another empty container up on the refuse wagon.

The method also comprises the steps as recited in claims 12 and 13.

By this satellite collection principle, minor road wear is achieved, with the small collection cars making garbage collection and depositing it in smaller depots, after which the large, ordinary collection vehicles drive to the incinerators / authorized landfills after they have collected.

5 Furthermore, a flexible, fast and efficient collection and energy savings are achieved. The satellite waste depots do not require approval from the authorities prior to collection to the incinerator, whereas the incinerator itself requires approval and is also located at great distances between them.

The invention will now be explained in more detail with reference to the drawing, in which fig. Figs. 1A-1B show a side view of a refurbished trolley with the rear panel in the retracted position and in the operating position, partly in section, Figs. 2 is a side view of a portion of a refuse wagon with a different type of rear piece in operating position, partly in section; FIG. Figs. 3A-3C show pictures of the rear wagon where the back cover has been removed for the sake of clarity and shows the operation of the lifting arms and the gripping 20 claws. 4 shows a close-up view of the lifting arm and claw; FIG. 5 shows a side view of a refurbishment truck with the rear panel in working position; FIG. 6 shows a side view of the refuse wagon with the tailgate tilted down and so that the container is no longer locked to the refuse wagon, 30 6 DK 173433 B1 fig. 7A-7C show the lid of the container and the locking mechanism in section and the location of the recesses; 8A-8B are a close-up view of the container locking mechanism; and FIGS. 9A-9I show the operation of the refuse collection truck in interaction with a collection vehicle and thus demonstrate the satellite collection method.

A wagon 1 is shown in FIG. 1A to 1B with a container 2 mounted on the la / 10 chassis and a cab 35 at the front, and at the opposite end, the rear member 3 is mounted slidably to the refurbishing vehicle 1. The rear member is seen in the figure in both the reversed position and in the operating position. For the sake of clarity, the lifting arms 13 for removing the container are not drawn. The back cover 3 is shown in section, showing the elements of the back cover. In the rear piece 3 is provided a auger 50, which is rotatable, which rotation is provided by a motor 51 which drives the auger shaft. The auger is otherwise designed according to known principles and thus comprises a shaft with turns. The auger is preferably located in the lower portion of the backing 3 and is inclined to form an angle of 5-25 'to the horizontal position. The auger is housed in a cylinder-shaped tube 58 which is open at the top 59 so that 20 debris can pass down to the auger. The cylindrical tube is also open at the other end 55. The other end 55 of the auger will, when the back piece 3 is in its operating position, ie. the entire back piece abuts against the container 2, extending through an opening 7 at one end of the container 2. This recess has a dimension approximately equal to the dimension of the cross-sectional area of the auger 50, however 25 shaped oval, to allow passage of the inclined auger. This ensures that only a minimum of waste falls out when the tailgate is pushed back.

The movement mechanism of the rear member 3 comprises a sliding guide 52, which sliding guide is mounted inside an auxiliary frame 53 arranged above or below the chassis frame of the car, and which sliding guide 52 is otherwise adhered to the lower part of the rear member 3. The sliding deflector is actuated by a hydraulic mechanism 54 mounted to bag DK 173433 B1, respectively, the tailpiece 3 and the wagon 1, preferably its frame. The mechanism has a stroke in the order of approx. 500 mm. This sliding guide, thus comprising preferably square profiles with abutments in the interior of the car's square auxiliary frame 53, causes the movements of the tailpiece to be unambiguous 5 and secure, and that the auger 50 is unambiguously moved into the recess / opening 7 provided in the container. rear end.

FIG. 1B shows how the auger 50 forms a sealing closure against the filling opening 7 of the container 1.

10

FIG. Figure 2 shows a side view of a refuse truck 1 with the rear member 3 in the operative position and where this is moved by means of a tilting mechanism and where the compression takes place by means of vanes. The back piece 3 thus holds a drawer 6 in which the waste falls down when filled into the back piece 3. The drawer 6 is moved in an upward movement by means of a hydraulic control device 24, while the upper blade 5 makes a downward turning movement and scrapes along the inner surface of the drawer 6 with its tip 37 along the surface and empties, shovels and compresses the waste through the filling opening 7 of the container 2 into the container 2. The drawer 6 is formed as a cavity, the end surface of which is formed by the side surfaces of the back piece. The upper blade is formed with a flat surface facing the container 2 in its resting position, that is when the surface abuts the opening 7. The blade extends throughout its transverse length as the transverse width of the drawer. The upper blade 5 is also activated by a hydraulic system 23.

Both cylinders 23, 24 have a stroke of the order of 400 mm. The cylinders 25 are both pivotally attached at points 40 and 41 to the end wall of the tailpiece 3 and at the other end are attached to the upper blade 5 of a pivot shaft 42 and, respectively, to the lower cylinder in a shaft attached to the lower drawer 6.

Thus, both the upper blade and the drawer can rotate at suspension points 42 and 43.

Both the upper blade 5 and the drawer 6 are pivotally attached to the front face 44 of the back piece at an upper pivot point 9 for the upper blade 5, which pivot is at a distance from the pivot point 10 of the drawer 6, which pivot points 9 and 10 are approximately the same vertical bearing, that is, approximately just above each other. In this construction, it is ensured that the upper blade 5 can make the shovel movement down into the drawer 6 and also form a sealing closure against the filling opening 7 of the container 5. The filling opening 7 is located in the rear end of the container 2, which opening is arranged in the upper share. The tailpiece 3 is attached to the trolley in two points, a lower point 4, which is a pivot around which the backpiece turns, and optionally in the form of a shaft. The tailgate is connected to the chassis of the truck via this pivot axis.

However, the rear panel could also be mounted by means of a sliding guide as indicated for the rear panel comprising a auger.

When the container 2 is filled with waste, the container must first be unloaded from the refurbishment truck 1 and then lifted off. FIG. 5 and 6 show the release of the container from the refuse wagon. At the top, the back piece 3 is attached to the container by means of a mechanically releasable locking device 20, which consists of a hook 21 which is attached to the back piece 3 and a receiving portion 22 formed on the container, for example shaped as a notch in which the hook fits down. As soon as the hook 21 is lifted, the entire 20 back piece can be displaced. The hook is operated by a hydraulic mechanism 57.

The displacement of the rear member 3 itself takes place by means of a hydraulic cylinder connection 54, and when activated, the rear member 3 is moved as previously discussed. The drawbar 25 is connected at one end to a lock 26 which enters the container 2 in a recess for this purpose. Also, when the back piece is displaced as a result of the movement of the cylinder 54, a pull occurs in the pull rod 25, which is connected to the cylinder 54 at the other end, which pulls in the locking device for the container a rotation about a rotary axis 27 of a lock 26 in the form. of a hook which engages in a recess around a axis of rotation 27. Hereby the container is detached from its connection to the refuse wagon. The container is thus DK 173433 B1 des released and ready to be put by the waste trolley by means of the raised levers.

Removing the container from the waste truck is shown in fig. 3A-3C and 4, FIG.

Figures 3A-3C show the lifting arm 13 in a resting position, after which the lifting arm is actuated and with its gripping claw 17 grips each end of the container around a knob 46, after which the lifting arms 13 in an arching movement move the container 2 to the side and place it on the ground. The gripper claw 17 can then loosen its grip around the knob 46, and the lifting arm may be in place. The refurbishment van is suitably equipped with a support leg to ensure that the weight from the containers does not cause it to tip over.

The function of the lifting arm 13 as well as the function of the gripper claw 17 will now be explained in more detail with reference to fig. 4th

15

FIG. 4 shows the lifting arm in three positions, partly in a resting position, partly in a position where it grips the container and partly in the position where the container is located on the ground. The lifting arm 13 consists of an arm 14 which is connected to the refuse wagon via a pivot point 48. A hydraulic cylinder 15 is connected to the arm 14 via a pivot point 48, so that upon activation of the hydraulic cylinder, which typically has a stroke in of the order of 125 mm, the arm 14 rotates about the pivot point 47 due to the extension of the hydraulic cylinder and thus displacement of the point 48.

The gripper claw 17, which also operates by means of a hydraulic system, is mounted on the arm 14 at its end. The gripper claw typically consists of two forks which can be spread out to an angle of about 180 'and assembled in total so that the two forks are parallel to each other and thus constitute an adjustable, but also an extremely secure gripping device around the container's 2 knobs 46. that the container 2 is disposed in a designated location, it must be emptied.

10 DK 173433 B1

FIG. 7 shows how the lid 29 of the container 2 is unlocked. The lid 29 covers an upper opening 36 through which the waste must be discharged. The lid locking mechanism is clearly shown in FIG. 8, showing that the lid is secured by a hook 33 which engages a recess provided therewith. The hook 33 is connected via a spring 5 39 to a connecting element in the form of a rod 32. The rod 32 attaches at its other end to a pressure plate 31, which pressure plate is arranged in a recess in which it can slide. The recess 30 provides space for the projecting parts of a lifting device to slide into the recess 30, and in this movement the gripping device strikes the pressure plate 31, and since the pressure plate 31 is slidably mounted by springs 38 in the recess 30, a vertical moving the plate, which in turn causes a pull in the connecting rod 32. The connecting rod 32 will, via its suspension system, being pivotally mounted to the upper part of the container, cause the hook 33 to move out of its notch, thus opening the lid 29. The recess 30 is located at the opposite end of where the filling opening 7 of the container 2 is located, and is typically placed in the side surfaces and mouths of the container into the end surface. Thus, so to speak, the space in which the lifting devices are to migrate is obtained free of charge. The lid 29 is now detached from the container, and when the lifting device 34 makes a lifting of the container by a rotating movement, the waste can thus fall out through the opening 36 into a device adapted thereto. large 20 collection containers.

The actual method of collecting waste is shown in FIG. 9 and will be explained in more detail below.

First, there is a filling of the container, the back piece being filled by means of a lift 56 which lifts the filled buckets up for emptying in the back piece 3, and from the back piece the waste is now transferred to the container 2 itself, the auger rotating and by means of its windings carry the waste into the container under compression. Thereby, the waste is compressed and filled into the container 2. The back piece may also conveniently accommodate a weight, so that it is possible to follow the amount of waste as a function of selected criteria. After the container is filled up, the refuse collection is driven to a collection station. The advantage of the renovation trolley is, among other things, that it is designed as a small and very flexible trolley, which due to its smaller weight is more environmentally friendly, since it does not strain and wear the roads as much as those otherwise known.

5

Thus, after the containers are filled, these will return to a collection station and the collection station is followed by the procedure of displacing the backing, releasing the lock to the container. The hydraulic lift arm then lifts off the container and places it on the side of the ground. The empty waste truck can now drive to the la-10 for empty containers and, with its lifting arm, reattach a container. The back cover is moved back into place and the container is locked to the waste truck.

As for the filled container, it is in "depot" with other filled 15 containers and emptied by means of a large collection recovery truck which, with a lifting device in the form of a vertically projecting claw, pushes it into the recess of the container, thereby activating the pressure plate front end and The collection truck now lifts the container into a vertical position and thus empties the contents of a large collection container arranged for 20 on the drawer of the refuse wagon. The containers of the collection refuse wagon are considerably larger than the small containers to be emptied. and the advantage is thus clearly evident, since the large collection trucks can thus drive to the collection points where the waste is located in the smaller containers, and thus can continue to the incinerators, etc. 25 which are current.

After the container has been emptied into the waste collection trolley, as mentioned, it is put back in place and can now be picked up by a waste disposal trolley which can use the empty container for collection of additional waste.

By this satellite collection principle, minor road wear is achieved, with the small collection cars making garbage collection and depositing it in smaller depots, after which the large, ordinary collection vehicles drive to the incinerators / authorized landfills after they have collected.

5 Furthermore, a flexible, fast and efficient collection and energy savings are achieved. The satellite waste depots do not require the approval of the authorities prior to collection at the incinerator, whereas the incinerator itself requires approval and is also located at great distances between them.
