Definitions

  • the invention relates to a loading and emptying device for a refuse vehicle comprising an endless carrier, running in a substantially vertical plane, one or more pick up members attached to the endless carrier and tilting means for tilting a container.
  • Such a device is known from the German Patent 432.470.
  • This known device has an endless carrier, consisting of two parallel chains, running in the longitudinal direction around the body of a refuse vehicle. Pairs of T- or U- shaped hooks are fixedly connected to the chains, which serve as pick up members for refuse containers.
  • a refuse container with a rod extending at both sides, is placed on a raised platform at the back of the refuse vehicle with the extending parts of the rod close to the endless carrier. The next pair of hooks pick up the container and transport it along the path of the endless carrier.
  • the container is brought into an inverted position by putting it over a steep bulge, whereby immediately after passing the top of the bulge it lands on a spring supported plate, in order to prevent it from falling out of the hooks.
  • the container After passing the refuse collecting compartment of the vehicle the container reaches the downwardly directed part of the path of the endless carrier, where it falls out of the hooks and with the extending parts of the rod into a pair of arc shaped guides upwardly directed, where it returns to its starting position.
  • the pick up member consisting of a pair of hooks
  • the endless carrier so that in order to tilt the container, the container has also to be repositioned relative to the pick up member.
  • the freedom of movement of the container is restrained by the chains of the endless carrier as a result of which the container has to be dropped out of the hooks in order to get it back to its starting position.
  • the container returns to its starting position at the front of the refuse vehicle. Because controlling the movement of the container requires a lot of space, tilting it through an angle of 180° and back again over the same angle; this known device is not suited to be placed at for instance the backside of a refuse vehicle.
  • the pick up member or pick up members are rotatably mounted on an attachment member or members, attaching the pick up member or members to the endless carrier by means of said attachment member or members, the axis of rotation being perpendicular to the plane of the endless carrier and the endless carrier having two horizontal parts and two vertical parts, and in that the tilting means consist of rolls on the pick up member or members and bosses and/or guides on the device, cooperating with said rolls, whereby the pick up member or members rotate through an angle of 180° or more at the angular points between the upper horizontal part and the two vertical parts and/or along the beginning and end of the upper horizontal part, the pickup member or members turning through an angle of 360° along the path of the endless carrier.
  • the container reaches its inverted position at the upper horizontal part of the path where it is emptied in a receiving member of the refuse vehicle. Because the container is tilted in two controlled steps through an angle of 360°, in order to empty the container and to bring it back in its starting position, the space needed for the device can be small enough to be able to locate the device at the backside of the refuse vehicle.
  • a container loading device is known with two parallel endless chains and a pick up member with U-shaped hooks connected to each other by a beam.
  • the hooks are to engage support means of a container which can be secured in the hooks.
  • the container goes upwardly to an inverted position and back to its starting position along the same path.
  • the tilting means consists of a boss in each of the corners between the upper horizontal and the two vertical parts of the path of the endless carrier and two rolls mounted on the pick up member on either side of the pivot point thereof, whereby the respective rolls engage the respective bosses with the movement of the pick up member through the upper bends of the path of the endless carrier.
  • the lower horizontal part of the path of the endless carrier is mounted at such a height, that there the pick up member is no longer in engagement with the container.
  • a container is picked up at the beginning of a vertical part of the path of the endless carrier where guides may be mounted to guide the container to the right position and is put back at the end of the other vertical part of the path, because the container touches the ground before the pick up member reaches the lower horizontal part of the path.
  • the container Shortly after the container is picked up it is secured to the pick up member, for instance with a clamp over the pick up cam.
  • the clamp is put into and out position when it passes certain points along the path of the endless carrier, which is a system known per se with refuse container loading devices.
  • a receiving member is provided, which is mounted beneath the upper horizontal part of the path of the pick up member and which is in downward direction at least partly funnel-shaped.
  • the receiving member extends from one side of the loading device to the other side thereof, where it connects to the usual receiving section of the refuse vehicle.
  • the invention provides that at the upper bends in the path of the endless carrier guides for a cover of the container are mounted, extending from where the tilting starts to outside of the receiving member.With these guides the cover of the container is guided from a closed position to a totally opened position and back to a closed position before reaching the next tilting phase of 180°.
  • These guides also enable to operate the device in a clockwise direction as well as in a anti-clockwise direction.
  • the tilting means consists of rolls on the pick up member, one at either side of its pivot point, a protruding part of the pick up member at a distance from the pivot point parallel to the pivot axis of the pick up member, which lies against the endless carrier along the vertical parts of the path thereof, and guides for the rolls and the protruding part of the pick up member which are mounted symmetrically with a vertical plane of symmetry intersecting the plane of the endless carrier perpendicular in the middle, whereby the guides for the protruding part are destined to tilt the pick up member from a normal or tilted position to an overturned position or vice versa and the guides for the rolls to tilt the pick up member from an overturned position to an inverted position or vice versa.
  • the top of the container is already above the receiving member when the container is only just slightly tilted, so that the danger exists of refuse dropping besides the receiving member.
  • further supporting means consisting of a roll between the pick up member and the endless carrier, rotatable around the pivot axis of the pick up member, a supporting beam therefor and an U-shaped guideway for the end of the attachment member or members, protruding at the other side of the endless carrier, the supporting beam and the U-shaped guideway extending at least along the greater part of the upper horizontal part of the path of the endless carrier.
  • the invention also provides that the wall of the receiving member has at least one detachable part.
  • the wall of the receiving member has at least one detachable part.
  • a first possibility is to mount two loading devices next to each other, whereby each receiving member connects to its own compartment of the refuse vehicle.
  • the number of pick up members per loading device have to be taken into account, and also a coupling between the two endless carriers of the devices has to be made, in order to let the different containers pass each other safely.
  • Another possibility is to provide a movable slide in the receiving member, which is suited for a system with a vertical separation or a system with a horizontal separation with control means to bring the movable slide in the correct position for each container.
  • a simple embodiment hereof is a manual operated control system with control means in different colours corresponding to the colour of the different containers.
  • the invention also provides in a cleaning device for containers which comprises a reservoir for a cleaning liquid, a number of spray nozzles directed upwardly, means to spray under pressure the cleaning liquid and receptacle for the used cleaning liquid.
  • This cleaning device can be put through the detachable part or parts in the wall of the receiving member into the receiving member and partly into the refuse vehicle.
  • the cleaning device according to the invention means a considerable improvement, which will meet the environmental demands to be expected in the future.
  • a refuse vehicle is indicated with 1 whereto a framework 2 with an interposed framework 3 is mounted.
  • sprocket wheels 4,5,6,7 are mounted, around which an endless chain is put, whereby one of the sprocket wheels, in the drawn example sprocket wheel 5, is provided with a driving member, which can be an hydraulic motor.
  • One or more pick up members 10 are attached to the chain 8. In fig. 1 one pick up member is indicated, but a framework of that size will operate in most cases at its best with four pick up members.
  • the pick up member 10 is attached to chain 8 in such a way, that the pick up member can move with respect to the chain parallel to plane wherein the chain 8 lies.
  • the pick up member 10 pivots about a shaft 17, located at some distance from the chain 8.
  • the pick up member 10 has a pick up cam 11 at some distance of the plane wherein the chain 8 lies, intended to engage the pick up strip 12 of a container 13, whereby also a support arm 14 is provided, which abuts against the side of the container 13 when the container 13 is taken along with the pick up member 10.
  • the pick up member has tilting rolls 15,16, which are mounted at each side and at the same distance of the pivot axis 17 of the pick member 10.
  • the tilting rolls 15,16 are intended to cooperate with tilting bosses 18,19 mounted on the sprocket wheels 4,5, whereby tilting roll 15 engages with boss 19 and tilting roll 16 engages with boss 18. Regardless whether the endless chain 8 runs in a clockwise or anti-clockwise direction.
  • a tilting roll 15,16 engages a tilting boss 18,19 and the tilting movement is started with the further movement of the chain 8.
  • a guide 20 for the tilting rolls 15,16 is mounted, which has a lower course near the tilting bosses 18,19 than in the central part of the guide 20 where the pick up member is moved in a vertical position.
  • the receiving member is indicated with 27, which is more of less funnel-shaped, seen from the back as well as from aside, and connects to the usual receiving space in the refuse vehicle.
  • doors 28 are mounted, through which other refuse then offered in containers, can be brought into the receiving space of the refuse vehicle without much effort.
  • the two guides 21,22 are indicated, which support the housing 23 of the container 13 with the guide 21 being mounted on the edge of the receiving member 27.
  • the guides 21,22 engage the rims of the housing 23 of the container 13 at the moment the tilting movement starts.
  • a guide for the cover 26 of the container is provided, which is mounted near the upper corner point between the guides 21,22 for the housing 23 of the container.
  • the cover 26 also engages this guide at the moment that the tilting movement starts.
  • the guide runs obliquely downwards at the position where the container is entirely above the receiving member, so that the cover may pivot open.
  • the cover runs along an identical guide only in opposite direction as a result of which the cover closes again.
  • the guide may be formed from a part of the sidewall of the receiving member, that runs sufficiently oblique in the direction of transport.
  • Fig. 4 shows another embodiment of the device according to the invention.
  • the endless carrier consists of two endless chains 8,8', which run over sprocket wheels 4,4',5,5',6,6',7,7'.
  • the pick up member 10 is attached to the two chains 8,8' by means of an attachment member 29, which also fixedly connects the two chains to each other.
  • the combination of two chains 8,8', pairs of sprocket wheels and an attachment member 29 that connects the chain, ensure a very stable suspension and pivot point for the pick up member 10.
  • the pick up member 10 further comprises a mounting plate 32, rolls 30,31, an extension part 33, in fig. 4 downwardly directed, and a protruding arm 34.
  • the parts 11,14,32,33,34 form a rigid construction which is pivotable around the protruding part of the attachment member 29.
  • the rolls 30 and 31 are mounted at each side of the mounting plate 32. These rolls 30,31 and the protruding arm 34, which is located at the opposite side of the pivot point with respect to the rolls 30,31, form together with the guides 35-38 inclusive the tilting means for the pick up member 10.
  • the protruding arm 34 extends parallel to the pivot axis till near the chain 8' in the rear. During the vertical parts of the path of the endless carrier the protruding arm 34 abuts against chain 8. Near the upper corner points guideways 35,38 are mounted for the protruding arm 34. The lower ends of these guideways are partly located between the sprocket wheels 4,4' and 5,5'.
  • Fig. 5 shows schematically the movements of the pick up member along the path of the endless carrier.
  • the tilting movement starts when the attachment member 29 reaches the upper sprocket wheel 4 or 5, where the vertical movement changes in a horizontal movement along the path of the chains, while the protruding arm continues the vertical movement, lying against the vertical part of chain 8.
  • the protruding arm 38 also prevents the pick up member 10 with the container 13 from swaying against the receiving member 27.
  • Fig. 6 shows schematically a side view of the pick up member 10 in an inverted position, without the pick up cam 11 and the supporting arm 14.
  • the attachment member 29 is fixedly connected to the chains 8, 8' by means of plates 39-42. To one end of the attachment member 29, at the left side in the drawing, a roller 43 is fitted, which runs in a U-shaped runway 44.
  • a roller 47 is fitted to the protruding arm 34, made of nylon for example, which is to run in the guideways 35, 38.
  • the attachment member 29 has the shape of a crankshaft, with the crank located between the two chains 8, 8'. This construction prevents the attachment member from engaging the guides 35, 38 for the protruding arm 34.
  • fig. 7 shows the device according to the invention with a cleaning device mounted in the receiving member 27, so that the refuse vehicle may now be used as a cleaning device for containers.
  • the cleaning device which can be mounted after the door or doors 28 are removed from the receiving member 27, comprises a reservoir 24 for a cleaning liquid, a receptacle 25 to receive used liquid and a pump 50 to wash out the containers with cleaning liquid through one or more spray nozzles 51.
  • a grid 52 may be mounted above the receptacle 25 for used cleaning liquid to retain possible residual refuse from the containers.
