Tipper arrangement for emptying a container into a collection bin

Abstract

A skip (2), having an external cavity forming a recess (2c), is equipped with a tipper (1) to allow, independently of the skip (which may be placed on the ground), the emptying of the contents of a container (10) by lifting and pivoting a structure of the tipper (1) beyond an upper edge (2d) of the skip (2). The structure, which supports the container via a gripping member, is movably mounted on a guide (4) coupled to a support (3) for attaching the tipper to the skip, within the recess (2c). The support (3) makes the supporting structure accessible on an external side. This structure is movable from a retracted position within the recess to lift and tip the container by pivoting when a pivot axis of this structure is sufficiently raised. A slide, which can define this axis, guides the lifting and supports the means for actuating the tipping.

Description

Technical field

[0001] The present invention relates to a container tipper for a collection vehicle, and in particular for waste collection, designed to ensure the unloading of the contents of a container into a skip, for example capable of being received at the rear of a vehicle. A collection vehicle equipped with such a tipper arrangement is also proposed. Prior art

[0002] In a known manner, a collection vehicle, used in particular for collecting waste, comprises a skip positioned at the rear of said vehicle, and is advantageously equipped with a tipper, configured to grip a container, at a lip surrounding the discharge opening of the container, and to tip said container relative to the skip, so as to cause the contents of the container to be discharged, under the effect of gravity, into said skip through an opening provided in this skip.

[0003] During a collection, it is necessary to transport each container to the roadway to place the container at the rear of the vehicle. Lifting the container from the rear does not help minimize the time and / or effort required by operators. In addition, the tipper generally interferes with the only passage through which the waste / products can exit the container.

[0004] Furthermore, systems for gripping containers from the side are generally bulky, complex and limited in their applications. Such systems are rarely adopted in practice.

[0005] According to the inventors' findings, there is still considerable room for improvement to facilitate operator interventions during unloading operations, by minimizing the loss of time during collection and / or by minimizing the time spent monopolizing resources. There is a need for a container tipper arrangement, transportable by a collection vehicle, comprising a skip with an upper opening (opening which can extend in a substantially horizontal plane), with improved reliability and reduced cost, operating and maintenance costs.

[0006] In order to improve the situation, there is provided a tipper arrangement for a skip, configured to effect the dumping of the contents of a container, by lifting and pivoting a supporting structure of the tipper beyond a lateral upper edge of the skip, the arrangement comprising: the skip which is provided with a front end and a rear end, between which extends an interior volume delimited by two side walls (typically right wall and left wall); the tipper provided with a support / fixing means connected to a first of the two side walls, the tipper including the mobile supporting structure, which has a container gripping member, with the particularity that the fixing support is fixedly (and rigidly) secured to the bucket and capable of making the supporting structure accessible on an external side of the first wall, this first side wall having at least one external cavity, forming a recess allowing the accommodation of: all or part of the supporting structure when retracted; lifting means for lifting the supporting structure; and at least one guide part, coupled or belonging to the fixing support and on which the supporting structure is mounted so as to be able to leave its retracted position.

[0007] With this arrangement, each container can be brought against a side wall of the skip equipped with the tipper, with ergonomics compatible with transport of the skip without the arrangement significantly exceeding the size of this skip. It is understood that the external cavity and the parts of the wall which delimit it can entirely form part of the size of the skip. Depending on the width of the skip, preferably near a front end thereof, a space dedicated to the tipper (external space) and a space dedicated to dumping (internal space) can thus be formed, these two spaces being separated from each other by a longitudinal portion of the wall of the first side wall.

[0008] It is also permitted to make the skip autonomous for unloading, without using a truck. With a suitable power supply (electric battery or similar) and the integration of a control unit, the tipper can be controlled independently, even if the skip is placed on the ground. This allows the truck to be freed up, so that it can only be used for transporting a skip loaded beyond a threshold or loaded for a cycle or storage period considered sufficient.

[0009] It is understood that flexibility in the tour or collection of the contents of the containers is obtained, with for example the possibility of unloading the skip which can operate autonomously, knowing that the tipper arrangement is secured to the skip, not to a truck chassis or other vehicle capable of transporting this skip.

[0010] The possibility of not modifying the truck is an advantage for use (possibility of filling the dumpster placed on the ground / using the truck or vehicle for another purpose).

[0011] In embodiments, the supporting structure may be supported by a slider or movable pivot part, which defines a pivot axis of the supporting structure. The slider is movably mounted on the guide part, for example in rails of this part. The slider may also carry one or more actuators (by an articulated attachment, typically), such as jacks, the movable head of which is coupled / fixed in an articulated manner to fixing means formed in the supporting structure, for example on an inner side of this supporting structure knowing that the gripping member is located on an outer side of the supporting structure.

[0012] It is understood that the slider and the cylinders / actuators can be entirely housed in the recess, in particular by being covered by the supporting structure which can form an element closing (at least in part) access to the recess, in the retracted configuration.

[0013] The slide and the actuators carried by the slide can be controlled by a control unit which activates for example a lift to first raise the slide, before actuating a relative pivoting of the supporting structure with respect to the slide. This succession of movements can be programmed to avoid pivoting the supporting structure when the pivot axis has not been sufficiently moved / lifted to reach or exceed the upper side of the bucket.

[0014] According to a particular feature, the arrangement comprises means for dismounting and / or moving the supporting structure, in order to place the gripping member outside the recess with this member moving away from the first wall. This can allow the gripping member to be shifted, for example to position this member at the level of a sidewalk edge. In options, this shift is done with an inclination allowing, in the event of lowering of the gripping member with a lower portion of the supporting structure, to follow an external lowering trajectory relative to a part of the underlying frame, present in line with the external cavity forming the recess.

[0015] In design examples, the movement of the gripping member, with partial disengagement of the supporting structure, may be a lowering by displacement of at least one portion (lower / lower portion) of the supporting structure, possibly at an angle. The means for disengaging the supporting structure may generate two movement trajectories, in order to move and shift this member into a lowered position. Such means are arranged by default behind the external face defined by the first side wall. The shifted position for the gripping member may therefore be obtained by displacement and / or deployment of the supporting structure from the retracted position, preferably by limiting the amplitude of the movement away from the external face: for example, the supporting structure may remain attached or almost attached to the chassis, for example by covering anti-underride barriers of the truck carrying the dumpster.

[0016] For the implementation of the tilting phase, the means for disengaging and / or moving the supporting structure may optionally comprise at least one tilting cylinder or actuator configured and controlled to initiate this tilting after a first substantially vertical (or slightly inclined) lifting phase, for example in a generally rectilinear direction defined by the guide part. Optionally, the gripping member may in this case move further and further away from the recess with a trajectory bypassing the recess from above. When this member is located at least at mid-height, it may already be offset (towards the outside of the first side wall) or still located in an upper half of the recess.In response to the extension of a cylinder or actuator which tends to push back the supporting structure with a rotation induced by an articulation of the structure on the shaft carried by the slide, the gripping member can pivot with the container: the tilting action results for example from the actuation of one or more tilting cylinders initially arranged vertically in the recess.

[0017] Optionally, the gripping member may be provided with a comb forming a lower part of a jaw of the supporting structure. The comb may have teeth oriented upwards in the retracted configuration. After tilting, they are inclined and oriented downwards, towards the interior volume.

[0018] The height level of the gripping member is adjustable in height, for example by using adjustment jacks or similar elements which can tilt with the supporting structure, under the action of lifting means separate from these adjustment jacks. More generally, the arrangement may include: lowering means for lowering the gripping member, from a first position corresponding to the height level occupied in the retracted position of the supporting structure, in order to reach a lowered position in a first operating mode of the tipper compatible with a configuration of the skip mounted on a chassis of a truck or collection vehicle, the supporting structure being located higher or extending above a base of the skip in said first position; and displacement means (a pair of lifting cylinders for example) for lifting, from the lowered position, the container suspended by the supporting structure to a second position of the gripping member, higher than the first position.

[0019] The moving means may further have actuator members, such as tilting cylinders, in order to actuate a pivoting of the supporting structure beyond the upper lateral edge. Optionally, one or more of the actuators include hydraulic or pneumatic cylinders, optionally cylinders allowing braking to be carried out at the end of the stroke of the cylinder in question. When cylinders are used for lifting and tilting, a vertical arrangement for each of these cylinders may be adopted, in the retracted configuration.

[0020] The tipper can be integrated in a compact manner, without extending beyond the body's outline or projecting downwards beyond a floor or lower surface of the body. This is a safety advantage: it is thus possible to keep the underride guards between the truck's wheels.

[0021] Embodiments of the arrangement provide one or more of the following: the moving means are interposed between a face delimiting the recess and the supporting structure, so as to integrate, for the retracted position, the tipper on one side of the skip without protruding outwards relative to a lateral external face of the skip in which the recess is formed. the skip is an "ampirole" skip (therefore capable of being separated from the collection truck / vehicle). In all that follows, an ampirole skip generally designates a box or a skip adapted to the system commonly called Ampliroll ®< (typically with a hydraulic lifting arm equipped with a hook which allows the skip to be loaded and deposited). the first position allows a second operating mode of the tipper which can be used when the skip is directly placed on the ground (therefore without being mounted on the chassis of the truck).the means for disengaging and / or moving the supporting structure comprise at least one actuator, coupled to a lower end of the guide part and capable of causing an angular pivoting of the guide part. the angular pivoting is carried out around an axis parallel to the first wall, this axis passing through or being arranged adjacent to an upper end of the guide part, at least when the tilting is initiated. the tilting arrangement comprises jacks, a first group of which actuates a movement of the supporting structure which is a movement typically without rotation due to a guidance, either direct or indirect, of this structure in two parallel rails (4a, 4b) belonging to the guide part (4), and a second group of which serves selectively to tilt the supporting structure (5).the second group may have cylinders secured to a slide which carries a pivot axis of the supporting structure, the slide opposing the rotation during movement made in response to the actuation of the first group of cylinders. the slide is mounted / capable of being secured to the supporting structure during its guided movement in the two rails. the cylinders of the first group may be located further back in the recess, against the first wall, than the cylinders of the second group. the cylinders (of the first and second groups) extend entirely into the recess, for example between two facing sides belonging to the bucket, so that they are covered by the supporting structure in the embedded position.the slider can define a frame, one side of which forms an articulation part (shaft to allow articulation) cooperating with coupling means, rotatably linked on this shaft and formed on a supporting structure, for example by being formed on the upper portion of this supporting structure.

[0022] In examples of the construction of the supporting structure, one or more of the following provisions may be adopted: the gripping member is provided with a comb forming a lower part of a jaw of the supporting structure, the comb being integral with a lower portion of the supporting structure which is selectively movable relative to the rest of the supporting structure. the supporting structure has two plates held parallel to each other which, in the embedded position, form partially overlapping portions. these portions are substantially arranged vertically in the embedded position. one of the two plates is adapted for gripping from the bottom of the container, for example by carrying a comb or similar member for gripping from the bottom. the other of the two plates is mounted articulated relative to an axis carried, directly or indirectly, by the guide portion.the lower portion is made selectively movable, relative to the rest of the supporting structure, using one or more actuators which are part of the lowering means, and are carried by an upper portion of the supporting structure. such actuators make it possible, by selectively raising the lower portion along the upper portion, to obtain pinching of a gripping edge of the container already engaged by the gripping member against a projecting rim formed on said upper portion.

[0023] According to a particular feature, the bucket has an electrical power source and a control station, connected to the power source, for controlling the tipper autonomously, for operation of the tipper compatible with a mode of use of the bucket directly on the ground.

[0024] The arrangement may be compatible with cleaning carried out from above the skip. All or part of the supporting structure may be used to guide the dumping, allowing it to be obtained, alone or in association with a partition or dumping ramp provided on the skip, a barrier effect above the recess in the tilted state. The arrangement, without requiring further intervention from an operator, promotes complete dumping of the contents of the container into the skip and return of the emptied container in a cleaned state.

[0025] According to one aspect, the invention also relates to a collection vehicle comprising: a vehicle chassis; a tipper arrangement as presented above, and a liquid reservoir fluidically connected to a cleaning tool for spraying the liquid, the reservoir being secured to the bucket, the cleaning tool being capable of spraying the liquid over the recess, above an axis allowing the pivoting of the supporting structure beyond the upper edge; in which the bucket carries the cleaning tool as well as a control interface for controlling the tipper and operating the cleaning tool.

[0026] According to another aspect, there is provided a use of the tipper arrangement for lifting and tipping a container, in which use the supporting structure is moved in a sequence comprising the following steps: partial disengagement of the supporting structure (typically without moving the tilting axis of the supporting structure out of the recess), preferably by tilting the guide part which is supported by an articulated connection on a top of the fixing part; after engagement of a container on the supporting structure using the gripping member, lifting of a hinge axis around which the supporting structure can pivot, by one or more lifting actuators; tilting of the supporting structure with the container held by the gripping member, by rotation around the hinge axis, until an overlap is obtained between: a plate forming one end of the supporting structure located above the gripping member in the retracted position, on the one hand; and a ramp covering the recess from above, on the other hand.

Description of the embodiments

[0028] Several examples of non-limiting embodiments are set out below in detail. In the various figures, identical references indicate identical or similar elements. Throughout the present application, and as visible in the examples of embodiment of the figures 1 to 5 And 7 , the Z direction designates the vertical direction of space while the bucket 2 is extended in a horizontal direction.

[0029] In reference to the Figures 1 and 2 , the tipper 1 is configured to carry out the dumping of the contents of a container 10, in a state mounted on a collection tank part for receiving these contents. With reference to the figure 1in particular, a skip 2 is provided to form such a collection tank part. The skip 2 has two side walls 200, 200', parallel to each other, which can delimit between them a significant interior volume V, for example exceeding one or several tens of cubic meters. The side walls 200, 200', with a front wall end 21 and a rear part 22 which can have at least one lockable door, make it possible to retain the materials, components poured into the interior volume V. The door of the rear part 22 can be hinged if necessary, for example around a horizontal axis when the door is made in a single pivoting block. When the skip 2 is capable of being separated from the truck (before or after each loading cycle, typically), for example by constituting an "ampirole" skip, the front wall end 21 can include a maneuvering socket 2b accessible from the outside.Each side wall 200, 200' extends upwards from a bottom 2a. The bucket 2 may optionally have an upper reinforcing belt. More generally, it is formed from upper edges, including an edge 2d provided on the first side wall 200 which includes an external cavity forming a recess 2c, so that the interior volume V is locally reduced on the side of the side wall 200, for example in an area distant from the rear part 22.

[0030] By choosing an “ampirole” skip, it is possible to easily tilt the skip 2 by raising the front wall end 21 where the operating socket 2b is located. This allows, if necessary, to move a collected part from the front to the rear in the interior volume. Alternatively or in addition, a movable floor and / or transfer means on board at a base 2a of the skip 2 can also participate in evacuating a collected part towards the rear, by making more available the space (of the volume V) located at the front and at which a container 10 maneuvered using the tipper 1 is unloaded. The bottom or base 2a can constitute or include a load-bearing floor. The skip 2, when it is of the “ampirole” type, can include one or more rollers r2 arranged on a rear side, two lower reinforcement and guide slides G1, G2.

[0031] The tilter 1 is provided with a member 1c or part for gripping the container 10 making it possible to block the container 10, for example by clamping or pinching against a comb 14 capable of coming from below a rim or lip 9 provided on the container 10. Such a rim / lip 9 is generally provided on the periphery of the upper end E10 of a container 10, where the opening O for filling and pouring (into the bin) is located. The comb 14 or similar relief assembly can be moved, for example lowered then slid to rise relative to the counter-comb 14', so as to hold and lift a container 10 by means of its rim 9.

[0032] The gripping member 1c is part of a supporting structure 5 for lifting and tilting the container 10. This structure 5 is movably mounted on a guide 4 which can prevent a rotational movement of the container 10. Thus, for a container 10 of standard size having a wide opening O, the guide part 4 contributes to linearly guiding a lifting of the structure 5 on which the container 10 remains attached. For example, the guide part 4 includes two parallel rails 4a, 4b which each extend between a lower end located in the lower zone of the recess 2c and an upper end located in an upper outlet zone of the recess or close to a top of the recess. An intermediate part of the tilter 1, for example only movable by sliding relative to the guide part 4, is guided in these rails 4a, 4b.As detailed below, the supporting structure 5 can be coupled in rotation to such an intermediate part which is designed for example as a slide 15 or sliding frame forming a movable shaft. Such a shaft 15a, visible in particular on the . figures 2 And 3C , is then mobile in sliding while allowing the pivoting of the supporting structure 5. The pivoting mounting of the structure 5 can be carried out by supporting the structure 5: on the one hand, by actuators, for example tilting cylinders VB which can tilt from first hinge fixing regions 15f provided on a cross member T15 or similar lower part of the slide 15, and on the other hand, by the shaft 15a which is installed in receivers or bearings C12 formed on the structure 5, knowing that in a retracted position of the supporting structure, the pivot axis A of the structure 5 is offset towards the bottom, that is to say is located closer to a bottom face of the recess 2c, relative to the connection of the supporting structure 5 with the end or cylinder head of the tilting cylinders VB.

[0033] More broadly, it is understood that the supporting structure 5 is movable around a pivot axis A which is movable in height, along the guide part 4. The tilting arrangement 100 may have actuators or means for disengagement and lowering operating independently of the actuators or lifting means ML. Thus, in the recess 2c, lowering means MA are provided making it possible to lower the gripping member 1c, from a first position corresponding to the height level occupied in the retracted position of the supporting structure 5, in order to reach a lowered position in a first operating mode of the tilting device 1 compatible with a configuration of the bucket 2 mounted on a chassis of a truck 60 or collection vehicle. In such a case, the supporting structure 5 in the retracted position (in this first position) may typically be located higher than this lowered position.The member 1c and, more generally, the main part of the supporting structure 5, extend above a base 2a of the bucket 2 to allow the arrangement 100 to be compact. Example(s) of rocker integration

[0034] In reference to the figures 1, 2 And 4-5 , the tipper 1 can be carried by the bucket 2 by being fixed in the recess 2c, so as to occupy a substantially parallelepipedal volume, for example with a height H1 of the tipper 1 which can be substantially equal to the height h2 of the receiving / tank part of the bucket 2. More broadly, the tipper 1 can be designed and dimensioned to be higher than it is wide, and with a depth limited to less than 55 cm, for example of the order of 40 cm, in a retracted state as seen in particular on the figure 4 .

[0035] The height H1 may slightly exceed the height h2, for example at the upper end E4 of the guide part 4. Optionally, the guide part 4 has tenons, similar axis elements or bearings 8 which make it possible to make this guide part 4 articulated around an axis X1 by being connected to the support 3.

[0036] A tilting actuation of this guide part 4 can be carried out in an area adjacent to or located at the bottom of the recess 2c, by using cylinders V1 or similar actuators capable of pushing outwards the lower end E4' of the guide part 4. In this option, the fixing support 3 can be designed to support the guide part 4 of the rocker 1 both by an upper end, which can carry parts of axes 4r or similar parts of a hinge or articulation (forming the axis X1), and by a lower end with the actuator(s) / cylinder(s) V1.

[0037] The guide part 4 can thus have a generally inclined orientation corresponding for example to the direction D' in the case of the figure 4 . This change of orientation also affects the entire supporting structure 5, insofar as the latter can be mounted movably on the guide part 4 by means of a frame or slider 15 which remains parallel to the guide part 4, for example by being interposed and guided between the two rails 4a, 4b. In this example of integration, the rocker 1 combines: a mobility of the guide part 4 (typically for an initiation of disengagement of the supporting structure 5); and a mobility of the supporting structure 5 which is driven by actuators (which do not cause movement of the guide part 4) to lift the container 10 and to tip it until its contents are poured into the interior volume V of the skip 2.

[0038] The actuators, in particular the VL cylinders of the tipper 1 capable of causing the lifting of the supporting structure 5, can be entirely held in the recess 2c, for example by each having a fixing connection 4c provided on a fixing support 3 allowing the guide part 4 to be secured to the bucket 2. This fixing connection 4c is compatible with rotation about an axis (which can be a horizontal axis) of each VL cylinder. A crossed arrangement of two VL cylinders can optionally be provided, as illustrated in the figures 2 And 4 , in order to compactly house these actuators for lifting the supporting structure 5. The cylinder heads ev of these VL cylinders, attached to the slide 15 via fittings 15c which may be opposite each other, are kept aligned along a horizontal axis.

[0039] Whatever the design specifically provided for the mobile part of the tipper 1, it can be bordered / arranged between two parallel sides of a similarly rigid, fixing frame or support 3, which remains fixed relative to the bucket 2. At least two crosspieces T3, one lower and the other upper, can connect these sides.

[0040] In the non-limiting case of the figure 2 , a fixing support 3 designed independently and fixedly mounted to the bucket 2 is shown, in order to support a guide part 4 which is typically distributed on two sides by forming rails 4a, 4b for the sliding of the movable part of the tipper 1. In alternative embodiments, the support may be an integral part of a wall 200 (first side wall) of the bucket 2, this support 3 being present / provided in the design of the bucket 2 in the latter case.

[0041] To allow mobility of the supporting structure 5 relative to the fixing support 3, a certain number of jack(s) or similar actuators may be provided. As can be seen in particular in Figures 7A and 7B , the actuators may be hidden (not visible in side view of the bucket) when the tipper 1 is in its rest configuration. A control unit or panel 16 may also be secured to the bucket 2, for example on a front side of the recess 2c, near the front wall end 21 of the bucket. A control interface, in connection with a cylinder control module, may be provided to be mobile within this control unit, for example to allow an operator to move away from the container 10 to be unloaded while still having remote control functions.

[0042] An intermediate sliding part or slider 15 and a tilting portion 12 can be coupled to each other, being able to adopt a parallel starting conformation (with overlap) in which the slider 15 is covered, in the recess 2, by a plate constituting the tilting portion 12. In the illustrated case, the tilting portion is an upper portion 12 which has connections with a lower portion 11 which partially covers it from the outside in order to make available a comb 14 facilitating the gripping of a container 10. In order to limit the size of the tilter 1 relative to the template of the bucket 2, for the retracted position of the supporting structure 5, it is understood that at least the slider 15 can extend into the recess 2c while being covered by the part or parts, preferably flat (arranged vertically), forming the tilting part of the supporting structure 5. Example(s) of kinematics of the supporting structure

[0043] The supporting structure 5, which may be substantially flat, extends for example along a substantially vertical plane in the retracted position which is a starting position. The gripping member 1c provided in the supporting structure 5 can operate without losing the flat conformation of the supporting structure. In advantageous options, the gripping member 1c consists of reliefs formed on an outer face of a lower portion 11 of the structure 5. This is for example a comb 14 forming a lower part of a jaw of the rocker 1. The lower portion 11 can then be a part mounted to slide along an outer face of another portion 12 of the structure 5 which is capable of rocking for a raised level of the supporting structure 5.In the retracted position, the portion 12 serves as a guide for the portion 11 and extends higher, including a counter-comb 14' or relief adapted to form a stop for the container 10 when the comb 14 is raised (due to an integral movement of the lower portion 11) as close as possible to the counter-comb 14'. The raising of the comb 14 is schematically reflected by the arrow T1 on the . figure 8 and may, if container 10 is seized, be immediately followed by an additional lift corresponding to the lifting of container 10 and the raising of axis A (lift reflected by arrow TL).

[0044] The jaw function of the supporting structure 5, which may be optional, makes it possible to easily block the container 10, by taking advantage of a selective mobility of the lower portion 11, permitted for example by cylinders or similar actuators forming lowering means MA. A lowering of the gripping member 1c may be provided, if necessary after an offset or disengagement of the latter to allow easier engagement of the container 10, in particular if the skip 2 is raised, for example by being mounted on a truck chassis 61 (see Figures 6 and 7A For example).

[0045] Once the container 10 has been gripped, it is understood that the portions 11 and 12, which are part of the supporting structure 5, remain fixed relative to each other, so that the container 10 remains firmly gripped both during a lifting phase (step 53 on the figure 8 ) than during a switchover phase (step 54 on the figure 8). Locking of the container grip 10 can be advantageously achieved while the container

[0046] In a first embodiment, the rocker 1 is capable of having three distinct movement trajectories relative to the fixing support 3 which remains fixed, namely: i) before taking a container 10, a trajectory allowing the guide part 4 to be moved relative to the fixing support 3 (which corresponds to a first movement trajectory, which may consist of a rotation); this allows for clearance in the event of lowering of all or part of the supporting structure and / or for at least partially disengaging the tipper 1 to facilitate the positioning of the container 10 (for example for non-carried / directly on the ground operation of the skip, without interference with a vehicle chassis);ii) after securing the container 10 with a lock (by pinching or other holding mechanism), a lifting along a trajectory TL which may be substantially linear, for example following the direction D' of extension of the guide part 4, knowing that the stroke of this trajectory TL may correspond to the displacement required to raise and place the pivot axis A in a position at least as high as the upper lateral edge 2d above which the container 10 is discharged; iii) when the pivot axis A has been sufficiently raised, a tilting following a rotation, corresponding to a selective displacement of the supporting structure 5 around the pivot axis A, which is for example formed in or carried by the slide 15, the rotation angle typically exceeding 100 or 120°, possibly without reaching or exceeding 160 or 170°. ;

[0047] The lifting applies to an assembly comprising a slide 15 and the supporting structure 5. The slide 15 includes connections 15c to follow the extension of the VL cylinders or similar active actuators to obtain the movement of this assembly along the TL trajectory.

[0048] It is understood that trajectories ii) and iii) can be chained sequentially, with the tilting following the lifting. On the figure 1 , direction D illustrates a non-limiting example of final inclination that can be obtained for the container 10 and the supporting structure 5 (here substantially flat) with which it is engaged. The opening O of the container 10 is thus oriented downwards at the end of the tilting, towards the interior volume V. With possibly the use of a ramp 24 covering the recess 2c from above, as visible in the example of the figure 10, the contents can be poured into the bucket 2. The ramp 24 can constitute a fluid-tight wall element, allowing liquid exiting through the opening O to flow into the interior volume V. The ramp 24 is optionally wider than the free end 5a of the upper portion 12.

[0049] In the tilted position, the portions 11 and 12 of the supporting structure 5 remain parallel to each other. The upper portion 12 then extends lower than the lower portion 11 due to the tilting (the pinching of the container rim 9 and the overlap between portions 11, 12 being preserved). The upper portion 12 may have an extension 12c, located beyond a zone of attachment to a shaft or axis element(s) making it possible to define the pivot axis A, so that this extension 12c is located higher and in line with the recess in the tilted position of the supporting structure 5, as can be seen in particular in the figure 10. The extension 12c may be located above (entirely above) the gripping member 1c in the retracted position. In the tilted position, an overlap may be provided between a plate forming this extension 12c (and thus forming the free end 5a of the supporting structure 5), on the one hand, and the ramp 24 on the other hand.

[0050] This ramp 24 can be either stationary and inclined (downwards), up to a dumping edge 24b, with an angle of inclination A5 similar to that of the structure 5 in the tilted state, or movable to reach this inclined position in response to an actuation of a drive member, for example by carrying out a downward thrust on a part of the ramp 24. The angle of inclination A5, substantially identical to that of the supporting structure 5 with respect to the horizontal, can be greater than 20°, for example between 30° and 75°.

[0051] This type of movement of the supporting structure 5 can be implemented both in the case of the Figure 7A , with the dump body on the chassis 61 of a truck 60, than in the case of the Figure 7B when skip 2 has been placed at a collection point, allowing truck 60 to carry out other transport operations.

[0052] When the bucket 2 rests on a chassis 61, not only is the supporting structure 5 movable by lifting and tilting relative to the support 3, but in addition the guide part 4 can also pivot, for example by being pivoted slightly in the recess 2c to bring out, out of the recess 2c, the lower end E4' of the guide part 4, for example as explained above using jacks V1 which, in an undeployed state, can have a length typically less than or equal to the depth of the recess 2c. The support 3 can be dimensioned with a depth L1 equal to or slightly less than the depth of the recess 2c.

[0053] In reference to the figure 2, the direction D' reflects for example an inclination of the guide part 4 which supports the supporting structure 5, by rotation around an angle which is possibly less than or equal to 15 or 20°. More generally, the arrangement 100 may have means for (partially) disengaging and / or moving the supporting structure 5, in order to make the gripping member 1c accessible, outside the recess 2c and for example allowing a lowering of this gripping member if necessary, taking into account the possible offset (in height) of the recess 2c relative to the ground. This can be achieved with a linear lowering trajectory (following the direction D', for example) passing close to the chassis but without interfering with the latter.

[0054] The offset of the guide portion 4 may be limited and the rocker 1 may be devoid of articulated arm(s) which may generate awkward bulk and / or control difficulties. As measured in a radial direction (perpendicular to the lateral face FL of the first wall 200), the lower end E4' of the guide portion 4 may be offset by less than 40 cm, for example less than 30 cm. By designing the supporting structure 5 flat, this amounts to limiting the offset of the gripping member 1c (which does not deviate too far from the recess 2c).

[0055] Such a movement of the guide part 4 around the axis X1 amounts to pre-positioning the supporting structure 5 in the direction D' ( figure 2) which is the guiding direction (cf. inclination of the guiding part 4, which may be generally less deep than the recess 2c in the initial / non-deployed configuration of the rocker 1) both during lowering and during lifting. This type of pre-positioning may correspond to an operating mode reflecting the case of the Figure 7A or similar.

[0056] The inclination of the guide part 4, which supports the supporting structure 5, is obtained by rotation around the axis X1 with an angle which is possibly less than or equal to 15 or 20°, compatible with the reduced depth dimensions of the guide part 4. The VL lifting cylinders or actuators can also be located set back (further towards the bottom) from the guide part 4, optionally by being supported by a lower portion of the guide part 4 which projects towards the bottom from rails 4a, 4b or similar guide uprights.

[0057] The movement of the guide part 4 can be actuated opposite the end E4 where the axis X1 is located, as seen in particular on the figure 4 , and can make it possible to limit the offset or disengagement to a lower part of the supporting structure 5 and / or to then avoid resorting to rotation to lift the container 10 along the side wall 200. In other words, the supporting structure 5 can be lifted by a simple linear displacement, at least initially to move the opening O of the container 10 substantially to the same level as the upper edge 2d. Non-limiting example of assembly and design of the supporting structure

[0058] In reference to the figure 2 , the fixing support 3 can make it possible to form one or more bearings 8 participating in supporting a frame or assembly with two rails 4a, 4b forming the guide part 4 of the rocker 1. The guide part 4 constitutes a mounting part for carrying / supporting: the lifting means, here in the form of VL lifting cylinders or actuators; and a sliding assembly including the slide 15 (possibly made from a single rigid block, as visible on the Figure 3C ) and the tilting device which constitutes the supporting structure 5 and allows the container 10 to be gripped.

[0059] In the illustrated cases, the supporting structure 5 consists mainly of two plates or portions 11, 12 with the lower portion 11 assembled as a partial covering plate of the upper portion 12, by covering a lower region of the upper portion 12. The slider 15 may be provided with two lateral flanges arranged internally, along the rails 4a, 4b of the guide part 4. A cylindrical section, forming the pivot for rotation of axis A, is provided in the slider 15 extending from one to the other of the two flanges, for example by being joined to respective upper ends of these flanges. The cylindrical section or shaft 15a participates in maintaining an arrangement of the supporting structure 5 which is, in the retracted configuration, parallel to the rails 4a, 4b.

[0060] The lower portion 11 may be mounted to slide relative to the upper portion 12 of the structure 5, with, where appropriate, guidance of the lower portion 11 between two wings 18 with return or lateral guides provided on the upper portion 12. A plate design may be adopted at least for one of the two portions 11, 12, so as to limit the depth requirement (in the recess) of the supporting structure 5. The lower portion 11 may overlap the upper portion 12, parallel to the latter, from the outside when the lateral guides / wings 18 are formed to project outwards relative to the rest of the plate constituting the upper portion 12.

[0061] The lowering of a comb 14 or similar gripping area of ​​the structure 5 may, in preferred options, be activated once the inclination of the guide part 4 has been obtained, which makes it possible, if necessary, to bypass embedding barriers 62, visible on the Figure 7A , and / or another part of the chassis 61.

[0062] As visible in particular on the Figures 7A-7B, the upper portion 12 includes a spill sub-portion formed by the extension 12c which extends above the counter-comb 14' in the retracted position of the supporting structure 5. During tilting, the contents of the container 10 can slide on the extension 12c forming this spill sub-portion. The lower portion 11, arranged as a comb holder, may include an insertion end E11 (formed higher than the comb 14) capable of being inserted under the extension 12c, knowing that the upper portion 12 may delimit, typically under the extension 12c, a sliding passage for the lower portion, this passage being able to be delimited between the two guide wings 18 distributed on two sides of the upper portion 12. Such a passage, of width Lb, may be substantially as wide as the width Le of the lower portion 11 as measured at the insertion end E11.In options, the format or perimeter of the lower portion 11 may be generally rectangular. The lower portion 11 and the upper portion 12 may form a tiltable device whose maximum width is - preferably - less than the spacing between the rails 4a, 4b of the guide part to allow total or partial embedding of the supporting structure 5.

[0063] In one embodiment option, the extension 12c may delimit a hollow and / or be offset outwards relative to the rest of the upper portion 12, so as to be able to cover the insertion end E11 provided in the lower portion 11. It is understood that the extension 12c may be designed to extend, at least in part, higher than the tilting axis A of the supporting structure 5, when the lifting cylinders VL or similar means are extended to raise the structure 5 (typically by raising the slide 15) and before the actuation of tilting cylinders VB, as in the case illustrated in FIG. figure 2 . More generally, the lifting force FL can result from the actuation of any pushing / lifting member which is installed in the recess 2c: between face F2 (visible face in particular on the Figure 5) of delimitation of this recess 2c, and the supporting structure 5 (with such organs located at the rear of the latter as clearly visible on the Figure 7A ).

[0064] In options, there is freedom of rotation for the guide part 4, so that the mounting of the rocker 1 offers the possibility of disengaging just a part of the supporting structure 5, typically allowing a lowering of all or part of the supporting structure 5 without extracting the lifting means from the recess 2c.

[0065] In reference to the Figure 3A, 3B , 4 And 7A, the supporting structure 5 can be coupled to a slider 15 whose coupling to the guide part 4 prevents it from rotating around the axis A which can be formed by the shaft 15a of this slider 15. Compared to the structure 5, the slider 15 is arranged further inside / at the bottom of the recess 2c. The supporting structure 5 is dimensioned so as not to protrude outwards or to protrude less than 10 cm outwards, compared to an external face of the guide part 4. This structure 5 can have a small depth / thickness, for example to represent an excess thickness e (without taking into account the comb 14 and the counter-comb 14') less than 10 or 15 cm compared to the slider 15, in the retracted position.

[0066] The supporting structure 5 may consist of only two parts, with only the upper portion 12 connected to the tilting actuators or cylinders VB, for example by fixing each head of the cylinder VB to a connecting element 12b rigidly formed on a rear face of the upper portion 12. Such a connecting element 12b may be offset lower than the pivot axis A and the position of the receivers or bearings 12 for the articulated coupling of the supporting structure 5.

[0067] It is understood that the jack(s) VB form actuating members for pivoting the supporting structure 5 beyond said lateral upper edge 2d, being activated only for a raised position as shown in the figure 2The cylinder(s) VB are here supported by the slider 15, via the first hinge fixing regions 15f, following the upward trajectory TL before deploying by pushing the supporting structure from the recess 2c, typically without the slider 15 leaving the recess 2c.

[0068] Referring now to the figure 1 Or 5 , it can be seen that the recess 2c only moderately reduces the width of the bucket 2, for example without the depth L1 or that of the recess 2c exceeding 25 or 30% of the nominal width of the interior volume V. The recess 2 has for example a depth limited to less than 50 or 55 cm, having a bottom face F2 which can be substantially vertical and / or parallel to the rest of the internal face of the first wall 200 (following the direction Z in the case of the figures).

[0069] Depending on the direction of the length of the bucket 2, the extension of the recess 2c can be limited to less than 2 meters, possibly less than 1.6 meters. On the Figure 7B , we see for example that the recess 2c can, along the wall 200, be delimited between two edges with a spacing d1 which represents less than 30% or 35% of the total length of the bucket 2, without overlapping / without interfering with the rear half Va of the interior volume V. Coaction of a tipper and a cleaning tool carried by the bucket

[0070] The tipper 1 may be associated with a cleaning device or tool 7 which is mounted on the bucket 2, so as to be able to direct one or more liquid spray jets inside the container 10 via the opening O when the latter is in the tilted position, above the upper side edge 2d. Optionally, side walls 200, 200' and possibly the front wall end 12 may have spray bars 17 or similar liquid spraying members for cleaning and / or rinsing the bucket from the internal side.

[0071] The cleaning tool 7 can be integrated on a front side of the bucket, for example without extending to the side of the rear half Va of the interior volume V.

[0072] The bucket 2 may carry a liquid tank T in connection with the cleaning tool 7 and, if applicable, with the spraying booms 17. The tank T may be located in the interior volume V, offset forwards relative to the dumping region / zone ZD. While the tank T extends essentially or entirely under the upper edge of the bucket 2, the cleaning tool 7 may be carried by the bucket 2 and installed movably so as to be able to move on top of the bucket 2, typically above the interior volume V so as not to interfere with the unloading enabled by the tipper 1.

[0073] In the non-limiting case of these figures 1 And 5, a chassis having two sides C1, C2 is arranged on the bucket 2 transversely, being fixed both on the top of the first wall 200 and on the top of the second wall 200'. The fixing on the first wall 200 can be carried out on either side of the upper end of the guide part 4. The spacing between the two sides C1, C2 can correspond to a wide zone including the zone ZD for unloading the contents of the container 10.

[0074] In variants, a frame of the cleaning tool 7 can be arranged only on one side relative to the spill region / zone ZD of the contents of the container 10 and / or only opposite the recess 2c, without connection to the first wall 200.

[0075] The frame C1, C2 or similar attachment support may extend cantilevered above the bucket 2, in particular from an upper edge 2g of the bucket which is opposite the edge delimited above the recess 2c, so that the cleaning tool 7 occupies by default a retracted position, being arranged at a distance from the upper edge 2d. This tool 7 may have one or more movable cleaning head(s) 7a. In practice, the movable head 7a is movable relative to the support or attachment frame, being able to be brought closer / moved towards the upper edge 2d of the first wall 200.

[0076] The cleaning head 7a is fluidically connected, for example via a suitable pipe or hose, to a liquid reservoir and adapted to spray the liquid above the upper edge 2 in a direction D7 away from the upper edge 2g (second edge) provided on the wall 200'. A pump for pressurizing the liquid may be provided in the circuit supplying the liquid to the cleaning head 7a.

[0077] In the retracted position, the tool 7 may be oriented differently, possibly having the head 7 closer to the second edge 2g than to the first upper edge 2d where the dumping takes place. The retracted configuration is thus distal from the first upper edge 2d, with, for example, a spacing of the tool 7 of at least half a bucket width from the pivot axis A.

[0078] An activation, via the control unit 16, can coordinate the movement of a VN cylinder or cylinder assembly to obtain an inclined position of the cleaning head 7a, which can extend to the extension position (maximum or with still a possibility of extension via the movement F7 if the cleaning head 7a has a telescopic design). As soon as the cylinder of the VN cylinder is extended to the maximum position, a controller of the unit 16 can adjust / activate the pump to start the spraying operation.

[0079] The cleaning configuration can be obtained by controlling a suitable actuator, for example at least one VN cylinder (visible in particular in Figure 5), which is for example started when the tilter 1 is in a tilted configuration which makes it possible to orient the opening O of the container 10 (grasped and lifted by the tilter) both in the direction of the interior volume V and opposite the second edge 2g. In the cleaning configuration, the tool 7 may have an elongation axis D7 which coincides with or is substantially parallel to: in the direction of a central axis the containers 10 passing through the opening O; and / or in the direction of inclination of the supporting structure 5 in the tilted state.

[0080] Typically in the cleaning configuration, due to the deployment of the tool 7, the cleaning head 7a may be closer to the edge 2d than to the opposite edge 2g, being placed in the spill region / zone ZD or higher and directly above this spill region. figure 10shows an example of positioning of the cleaning tool 7 enabled by a rotational movement which tends to lift the cleaning head 7a. This lifting may involve a rotation with straightening of the tool 7 then possibly a lowering of the latter until the axis X7 of elongation of the tool 7 is oriented towards an interior of the container 10 held in cantilever by the tilter 1). On the figure 1 Or 5, it can be seen that the supporting frame 6 or equivalent mobile support, on which the cleaning head 7a is fixed, is mounted articulated on the fixed chassis C1, C2. This arrangement can make it possible to store the cleaning tool 7 flat, with the chassis C1, C2 substantially horizontal, with simple single rotation kinematics which can limit the rotation angle (to less than 180°, for example to less than 150°) of the supporting frame 6 to make it possible to reach the cleaning configuration. The movement of the supporting frame 6, from above, is compatible with a skip 2 whose loading height is significant, for example significantly exceeding the mid-height of the skip.

[0081] Alternatively, as seen on the figure 9, a sliding movement can be actuated, along a substantially horizontal guide, here a rail element R for example, which is mounted on top of the bucket 2, by using a mounting support SM (carrying the tool 7) capable of sliding in a transverse direction perpendicular to the length extension of the bucket 2. The mounting support SM is configured to slide and, simultaneously, straighten up in a more raised position, to extend in an inclined orientation of a direction similar to that (direction D7) shown in the figure 10. A sliding connection 7c of the SM holder, possibly using a roller, a rack or the like, may be combined with pivot connection parts 70, 72, attached to the SM holder on which the tool 7 is mounted. In response to the extension of one or more cylinders VN towards the edge 2d, here to pivot upwardly the connection arm(s) 72 which is / are hingedly connected to the guide without the possibility of sliding, the entire SM holder is pulled towards the edge 2d while further tilting the tool 7 due to the rotation of the SM holder around a movable axis A7 (movable along the rail element R in the case of the figure 9 ) coinciding with the roller or similar sliding member.

[0082] Regardless of the design option precisely chosen, the cleaning tool 7 can be approached from the edge 2d by a support or carrying frame 6 or SM, if necessary with the possibility of actuating a telescopic movement (see arrow F7 on the figure 1) of the cleaning head 7a when the latter is already in its operational orientation for spraying liquid. This arrangement with a telescopic mounting of the cleaning head, movable relative to a body which may be tubular, makes it possible to achieve an end of movement of the cleaning head 7a to approach it (or accentuate the approach of the latter) to a bottom zone of the container 10 whose contents have just been poured. More generally, the cleaning tool may have a selectively movable design of the cleaning head, preferably so as to allow it to extend above / in line with the recess or similar integration zone of the tilter (or even beyond such an area), typically to insert itself inside a container 10 which is tilted.

[0083] In the illustrated options, the cleaning head 7a is pivotable, for example by being made rotatable relative to its mounting bracket SM, 6, so that it can be angularly moved away from the operational direction for spraying liquid. Being able to move the cleaning tool 7 away / move more than 90° between the retracting configuration and the cleaning configuration can facilitate assembly of the tool. Example of moving a container

[0084] First, a case is described with the bucket 2 raised above the ground, typically supported by a vehicle chassis 61. In this context, the tipper arrangement 100 can allow the supporting structure 5 to be lowered to leave the retracted position, preferably without deploying the gripping member 1 too far from the plane P of the wall 200 where the tipper 1 is located. The container 10 is previously opened, by moving the lid into a folded position against a side of the container 10 which is typically the one opposite the side engaged by the gripping member 1c.

[0085] As shown on the Figures 6 and 7A, before engaging an open container 10 on the tipper arrangement 100, the supporting structure 5 can be previously moved, from the embedded position, without extracting any tipping axis A of the structure 5 outside the gauge of the bucket 2, such an axis A then being able to be kept in the recess 2c. It is in response to the actuation of lowering means MA that the lower portion 11 of the supporting structure 5 can be lowered to allow the engagement of a comb 14 or similar gripping zone on a container 10, on one side of the bucket 2, for example without lateral spacing d (cf. figure 6 ) greater than 40 or 50 mm between the container 10 and the plane P of the corresponding side face FL of the bucket 2, when the lower portion 11 is lowered, which corresponds to a step 52 on the figure 8 .

[0086] When the lower portion 11 is above (again above in the event of prior lowering) the base or bottom portion 2a of the bucket, it is understood that the container 10 lifted by the structure 5 remains held close to the face FL. The assembly of the structure 5 can be adapted so that the container 10 gradually approaches the face FL at the start of lifting, optionally without the container 10 entering the recess 2c (which is already occupied by the actuators V2, VL, VB).

[0087] The lowering step 52 may be conditioned on the performance of a prior step 51 of changing the orientation of the guide part 4. The lowering means MA may include actuators specifically carried by the supporting structure 5, in an upper portion 12 thereof, in order to be able to selectively lower the lower portion 11, without displacement of another component of the rocker 1. The lower portion 11 may include, near its lower edge and in an area which does not overlap with the portion 12, fixing lugs 11p for the respective connection to one end, for example a cylinder head, of the actuators / cylinders V2. As shown in the figure 2, such legs 11p may project inwards / rearwards to allow a rear connection of the portion 11 to jacks V2 which remain hidden in the recess behind the structure 5, despite an overlapping arrangement from the front / outside of the lower portion on the upper portion 12. The jacks V2, which are carried by the upper portion 12 via fixing fittings 12f, may extend essentially to the rear of the upper portion 12, protruding from below for attachment to the portion 11 with a downward extension capability to obtain the selective lowering of the lower portion 11.

[0088] Prior to the lowering of the lower portion 11 or similar comb-carrying portion, as illustrated in figure 4 Or 8, the guide portion 4 may be slightly inclined relative to the vertical in the initial step 51 of orientation change, then remaining fixed in such an inclined position without the ability to rotate. Alternatively, as in the case illustrated in the figure 4 , the guide part 4 can rotate slightly from an initial vertical position in order to combine an optimal embedding in the recess 2c (in vertical conformation) and a possibility of lowering the lower portion 11 without resorting to a rotation, by bypassing the truck chassis 61 (the recess 2c being located directly above a part of the chassis 61, as illustrated in the Figures 6 and 7A ).

[0089] A phase of raising the lower portion 11 may then be required to wedge and block the container 10. As seen in particular on the figure 8, the lifting means V2, VL (here with hydraulic cylinders or similar actuators) can allow a lifting step 53, which can be broken down into: a first trajectory movement T1, during which the jacks V2 rise with the lower portion 11 to return the comb 14 or similar gripping reliefs closer to the counter-comb 14' or similar stop part provided on the upper portion 12 (which makes it possible to block / lock the container in the gripping position); then a second trajectory movement TL, possibly without deviation from the overall rise trajectory knowing that the guide part 4 can remain fixed at this stage.

[0090] On the figures 2 And 4, a sliding mounting of the supporting structure 5 is shown by using rails 4a, 4b belonging to a guide part 4 which extends over most or all of the height of the recess 2c, possibly even protruding from the top by an additional height h1 to allow an articulated mounting of the guide part, by means of the bearings 8 or similar mounting parts which are provided on either side of an upper outlet of the recess 2c, along the face FL. Thanks to this arrangement, the container 10 can remain particularly stable, without the slightest pivoting, during a lifting phase which corresponds to the accumulation of the trajectory T1 and the trajectory TL, during the lifting step 53.

[0091] The supporting structure 5 can thus be lifted without rotation relative to the guide part, if necessary after having pushed back the bottom of the guide part 4 via the actuators V1 (see also arrow F1 on the figure 4 ), to slightly tilt the part 4 by a rotational movement around the axis X1 defined by the pivot connection in the bearings 8. Such actuators V1 can be fixed directly to a lower portion of the side wall 20 or to the support 3, in a fixing region RF which is located for example under the guide part 4 by being distributed on two sides. The fixing region RF is for example distributed on either side of the rails 4a, 4b or according to an equivalent assembly which (just like the arrangement of the rails 4a, 7b) does not interfere with either the lowering or the lifting of the supporting structure 5.

[0092] In reference to the figures 1 , 5 And 7B, the movement of the container 10 can be carried out in a similar manner for a skip 2 whose bottom 2a delimiting the interior volume V is very close to the ground, for example only separated from the ground by slides G1, G2 or without resting on a separate chassis 61. In this case which corresponds to a second mode of operation, at least one of the steps 51 and 52 can be omitted: for example the container 10 can be attached to the lower portion 11 without step 52 of lowering the latter. For this, it is sufficient to choose a resting height of the comb 14 which is not very high (for example of the order of 1 meter or less) compatible for gripping from below the lip 9 of a container whose height is generally standard and between 1100 and approximately 1300 mm, typically.

[0093] In variants, the arrangement 100 can be configured to operate only in an operating mode without lowering the gripping member 1c below the base level of the bucket 2. This can simplify the tipper 1 while benefiting from optimized space requirements when transporting the bucket 2.

[0094] As visible on the figure 5 in particular, the tipper 1 operates without any actuator used in the lifting and tipping of the container 10 extending from above or on the sides of the container 10, which makes this operation safe for the operator. If necessary, support or a command optimizing the safety of the latter may be required to force the operator to move away from the container, for example by typically placing himself facing the control unit 16, therefore without being located in the movement zone of the structure 5 and the container 10 during unloading.

[0095] The tipper arrangement 100 can be obtained with a modular design, for example with components designed separately from the bucket 2, the only particularity of which may be to have a recess 2c of width and depth corresponding to the space requirement of the tipper 1. If necessary, a tilting floor mechanism and / or a scraping device, for example for moving contents of the bucket 2 towards the rear, can be provided.

[0096] Furthermore, the 2nd bucket can be made more or less short, with the possibility of adding an extension to the bucket, for example on the rear side, if you want to increase the storage capacity.

[0097] The tipper arrangement 100 provides a retracted position of the supporting structure 5, with a height level (at rest) of the gripping member 1c which can be compatible with the placement of the bucket 2 on the ground, therefore without a part projecting downwards relative to the underside of the bucket. With the supporting structure 5 which is thus located higher or above a base 2a of the bucket 2, the presence of lowering means MA allows this arrangement 100 to be compatible with the first mode of operation of the tipper 1 compatible with the bucket 2 mounted on a chassis of the truck 60, while also being able to operate according to the second mode of operation, without lowering.

[0098] The control of the actuators V1, V2, VL, VB and the cleaning system (via at least one actuator or cylinder VN and a device for delivering the liquid for spraying) can be done via a control unit 16 which is automatic, typically compatible with an emergency stop control. Such a control unit 16 can make it possible to automatically carry out a relative movement of the washing / cleaning head 7a according to at least one washing cycle comprising a programmed succession of movement steps.

[0099] More broadly, for cleaning efficiency, the control unit 16 may have an automatic detection system associated with a VN cylinder or other member representing the effective movement of the head 7a and / or the tilted positioning of the container 10. This detection system is thus capable of automatically detecting that the head 7a (for example tilted into the dumping zone ZD) and the container 10 (tilted) or the supporting structure 5 which supports it are in the desired positions.

[0100] A time delay before the activation of the cleaning can be provided, in order to ensure that the contents of the container 10 have been able to be discharged. Optionally, the movement of the frame or mobile support 6, SM can be integrated into such a time delay in order to allow a rapid sequence between the tilting phase, the unloading time, and the start of the spray cleaning, thanks to the cleaning head(s) 7a held cantilevered above the interior volume V.

[0101] The cleaning head(s) 7a are used to clean the inner wall of the container 10, which may be a bin, a recycling bin, or the like. Once cleaning is complete, in accordance with the program of the controller / control unit 16, the water / liquid pump can be closed. An adjustment of the telescopic cylinder, if any, is made to retract each cleaning head 7a, and then the tilting cylinder of the VN jack is retracted. The cleaning operation is complete, and then the container 10 returns to its starting position close to the bottom of the recess 2c. The jaw can be loosened to allow the container to be disengaged from the similar gripping member 1c, by raising it relative to the comb 14, for example.

[0102] In reference to the figure 6, 7A et 7B , a collection vehicle 60, such as a truck, may incorporate the tipper arrangement 100 and the cleaning system, possibly without any direct modification to the truck portion. It is understood that, when the skip 2 carries the components of the tipper 1 and the control unit 16 (if applicable with the associated power source(s)), neither the chassis 61 of the truck nor other vehicle parts are required to control the tipper 1. The tipper 1 and the cleaning system may be controlled by a control unit 16 which, for example, activates the lifting to first raise the slider 15 or similar non-tilting portion of the tipper 1, before actuating a relative pivoting of the supporting structure 5 relative to the slider 15.Such a collection vehicle 60 may for example be a heavy goods vehicle used for collecting waste, intended to transport the skip 2 for receiving waste or materials to be recovered which are stored in containers 10.

[0103] The succession of movements can be programmed according to a sequence which avoids pivoting the supporting structure 5 prematurely, in particular when the pivot axis A has not been sufficiently moved to reach or exceed the lateral upper edge 2d of the bucket 2 at the level of which and / or above which the dumping zone ZD extends. An associated control interface and in connection with the control unit 16, for example an interface of the HMI (human-machine interface) type, makes it possible to control the tipper 1 and to operate the cleaning tool 7 in an intermediate phase between a lifting step with tilting (of the supporting structure 5) and a step of returning the container to the ground involving a rotation and a descent of the supporting structure 5.

[0104] The advantages described above concerning the arrangement 100 with tipper 1 also apply to a collection vehicle 60, for example a truck, equipped with such an arrangement 100. Concerning the integration of the cleaning system, it is understood that all or part of the components of this system can be linked to a truck or vehicle chassis, for example in options allowing the tank T to be located outside the interior volume V of the skip 2.

[0105] Where appropriate, the cleaning system is modular, with some of the components being removably attached to the bucket 2 so that they can, where appropriate, operate with the tipper in a bucket configuration that operates independently. For example, it is permissible to install the cleaning tool 7 and / or the associated tank T removably on the bucket 2, possibly with only the tank T arranged in the interior volume V.

[0106] It should be obvious to those skilled in the art that the present invention allows embodiments in many other specific forms without departing from the scope of the invention as claimed. For example, even if the case of a skip 2 of the “ampirole” type has been illustrated, being loaded onto a truck 60 having a specific lifting tool to enable the skip to be moved by engagement on the operating grip 2b, other types of mechanism may be used for moving the skip 2 and / or the vehicle may consist of another transport vehicle, for example a boat (barge, cargo ship or similar) or a suitable rolling machine.

[0107] Furthermore, container 10 has been shown with casters on the figures 1 And 5but any other suitable container can be lifted and tilted, by adapting the structure of the gripping member 1c or the supporting structure 5. For example, a container 10 in the form of a pallet box, visible on the figure 11 , can be lifted using a gripping member 1c having a (lower) lifting part (fork for example) from below such a container 10, typically supplemented by an (upper) gripping / holding part from above. A vice-like grip of the container 10 can be achieved, between the support formed by the lifting part and the other part.
