Abstract
Description
Title of the invention: Tipper arrangement for emptying a container into a collection bin. Technical field
[0001] The present invention relates to a container tipper for a collection vehicle, particularly a waste collection vehicle, designed to unload the contents of a container into a skip, for example, one that can be mounted on the rear of a vehicle. A collection vehicle equipped with such a tipper arrangement is also proposed. Previous technique
[0002] In a known manner, a collection vehicle, used in particular for the collection of waste, has a skip positioned at the rear of said vehicle, and is advantageously equipped with a tipper, configured to grasp a container, at the level of 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 said skip. During collection, each container must be moved to the roadway to be placed at the rear of the vehicle. Lifting the container from the rear does not minimize the time and / or effort required by operators. Furthermore, the tipper typically obstructs the only opening through which waste / products can exit the truck.
[0003] Moreover, systems designed to laterally grasp a container are generally cumbersome, complex, and limited in their applications. Such systems are rarely adopted in practice.
[0004] According to the inventors' findings, there is still considerable room for improvement in facilitating operator interventions during unloading operations, by minimizing downtime during collection and / or minimizing resource monopolization time. There is a need for a container tipper arrangement, transportable by a collection vehicle, comprising a skip with a top opening (an opening that can extend in a substantially horizontal plane), with improved reliability and reduced operating, maintenance, and production costs.
[0005] In order to improve the situation, a tipper arrangement for a skip is proposed, configured to empty the contents of a container by lifting and pivoting of a tipper support structure 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 internal volume delimited by two side walls (typically right wall and left wall); - the tipper equipped with a support / fixing means connected to one of the two side walls, the tipper including the mobile load-bearing structure, which has a container gripping device, with the particularity that the fixing support is fixed (and rigidly) attached to the skip and capable of making the load-bearing structure accessible on an external side of the first wall, this first side wall having at least one external cavity, forming a recess allowing for the accommodation of: - all or part of the load-bearing structure when it is retracted; - lifting means used to lift the supporting structure; and - at least one guide part, coupled to or belonging to the fixing support and on which the supporting structure is mounted movably, able to leave its retracted position.
[0006] With this arrangement, each container can be positioned against a side wall of a skip equipped with a tipper, with ergonomics compatible with transporting the skip without the arrangement significantly exceeding the skip's dimensions. It is understood that the outer cavity and the wall sections that define it can be entirely within the skip's dimensions. Depending on the skip's width, preferably near one of its front ends, a space dedicated to the tipper (outer space) and a space dedicated to emptying (inner space) can thus be created, these two spaces being separated from each other by a longitudinal section of the first side wall.
[0007] It is also permissible to make the skip autonomous for unloading, without the need for a truck. With a suitable power supply (electric battery or similar) and the integration of a control unit, the tipper can be operated independently, even if the skip is resting on the ground. This frees up the truck, reserving it only for transporting a skip that is overfilled or has been filled for a sufficient storage period. This provides flexibility in the collection route or the collection of container contents, for example, by allowing the skip to unload autonomously, since the tipper mechanism is attached to the skip itself, not to a truck chassis or other vehicle designed to transport it. The possibility of not modifying the truck is an advantage for use (possibility of having the skip placed on the ground filled / using the truck or vehicle for another purpose).
[0008] In embodiments, the load-bearing structure may be supported by a slide or movable pivoting part, which defines a pivot axis for the load-bearing structure. The slide is movably mounted on the guide part, for example, in rails of this part. The slide may also carry one or more actuators (typically by means of an articulated attachment), such as cylinders, whose movable head is coupled / fixed in an articulated manner to fastening means formed in the load-bearing structure, for example, on an inner side of this load-bearing structure, given that the gripping member is located on an outer side of the load-bearing structure.
[0009] It is understood that the slide 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. The sliding block and its actuators can be controlled by a control unit that, for example, activates a lifting mechanism to raise the sliding block first, before initiating a relative pivoting of the supporting structure with respect to the sliding block. This sequence of movements can be programmed to prevent the supporting structure from pivoting when the pivot axis has not been sufficiently moved / raised to reach or extend beyond the upper side of the skip.
[0010] According to one particular feature, the arrangement includes means for disengaging and / or moving the supporting structure in order to position the gripping member outside the recess, with the gripping member moved away from the first wall. This can allow the gripping member to be offset, for example, to position it at the level of a curb. In some options, this offset is achieved with an inclination that allows, if the gripping member is lowered with a lower portion of the supporting structure, to follow an outward lowering trajectory relative to a portion of the underlying frame located directly above the external cavity forming the recess.
[0011] In design examples, the movement of the gripping member, with partial unfixing of the supporting structure, can be achieved by lowering at least one portion (lower portion) of the supporting structure, possibly at an angle. The means for unfixing the supporting structure can generate two movement trajectories, in order to move and offset this member into a lowered position. Such means are arranged by default behind the external face defined by the first side wall. The offset position for the gripping member can therefore be obtained by moving and / or deploying 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 can remain attached or almost attached to the chassis, for example by covering the underrun protection barriers of the truck carrying the tipper.
[0012] For the implementation of the tilting phase, the means for disengaging and / or moving the supporting structure may optionally include at least one tilting cylinder or actuator configured and controlled to initiate this tilting after an initial lifting phase that is substantially vertical (or slightly inclined), for example, along a generally straight line defined by the guide section. Optionally, the gripping member may in this case move further and further away from the recess with a trajectory that bypasses the recess from above. When this member is at least halfway up, it may already be offset (towards the outside of the first side wall) or still located in the 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.
[0013] Optionally, the grasping member may be provided with a comb forming the 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 internal volume.
[0014] The height level of the gripping member is height adjustable, 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 layout may include: - lowering means enabling the gripping member to be lowered 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 the 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 - means of movement (a pair of lifting jacks for example) allowing the container suspended by the supporting structure to be lifted from the lowered position to a second position of the gripping device, higher than the first position.
[0015] The means of movement may also be equipped with actuators, such as tilting cylinders, to actuate a pivoting of the supporting structure beyond the upper lateral edge. Optionally, one or more of the actuators may include hydraulic or pneumatic cylinders, and optionally, cylinders for braking 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.
[0016] The integration of the tipper can be compact, without exceeding the dimensions of the tipper body or extending downwards beyond the floor or lower surface of the tipper body. This is an advantage in terms of safety: it allows the underrun protection bars to remain between the truck's wheels.
[0017] Some embodiments of the arrangement include one or more of the following provisions: - the means of movement are interposed between a delimiting face of 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 an external lateral face of the skip in which the recess is formed. - The skip is an "Ampliroll" skip (therefore able to be separated from the collection truck / vehicle). In all that follows, an Ampliroll skip generally refers to a container or skip adapted to the system commonly called Ampliroll® (typically with a hydraulic lifting arm equipped with a hook that allows the skip to be loaded and unloaded). - the first position allows a second operating mode of the tipper usable when the tipper is placed directly on the ground (i.e., without being mounted on the truck chassis). - the means for disengaging and / or moving the load-bearing structure include at least one actuator, coupled to a lower end of the guide part and capable of causing an angular pivoting of the guide part. - angular pivoting is carried out around an axis parallel to the first wall, this axis passing through or being positioned adjacent to an upper end of the guide part, at least when the tilting is initiated. - the rocker arrangement includes cylinders, a first group of which actuates a movement of the carrier 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 is used selectively to rock the carrier structure (5). - The second group can have cylinders attached to a slide that carries a pivot axis for the supporting structure; the slide, opposing rotation during movement, actuates the first group of cylinders in response. - The slide is mounted / adapted to be fixed to the supporting structure during its guided movement in the two rails. - the cylinders of the first group can 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 group) extend entirely into the recess, for example between two opposite sides belonging to the skip, so that they are covered by the supporting structure in the embedded position. - the slider can define a frame one side of which forms a part of the joint (shaft to allow a joint) cooperating with coupling means, rotationally linked on this shaft and formed on the load-bearing structure, for example by being formed on the upper portion of this load-bearing structure.
[0018] In examples of implementation of the load-bearing structure, one or more of the following arrangements may be adopted: - the grasping organ 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 mobile 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 arranged approximately vertically in the embedded position. - one of the two plates is adapted for gripping the container from the bottom, for example by wearing a comb or similar bottom-gripping device. - the other of the two plates is mounted articulated with respect to an axis carried, directly or indirectly, by the guiding part. - the lower portion is made selectively mobile, relative to the rest of the supporting structure, by means of one or more actuators which are part of the lowering means, and are carried by an upper portion of the supporting structure. - such actuators allow, by a selective raising of the lower portion along the upper portion, to obtain a pinching of a gripping edge of the container already engaged by the gripping member against a protruding edge formed on said upper portion.
[0019] According to one particular feature, the skip has an electrical power supply and a control station, linked to the power supply, to control the tipper autonomously, for operation of the tipper compatible with a mode of use of the skip directly on the ground.
[0020] The arrangement can be compatible with cleaning carried out from the top of the skip. All or part of the supporting structure can be used to guide the emptying, enabling it to create, alone or in combination with a partition or emptying ramp provided on the skip, a barrier effect above the opening when the skip is tilted. The arrangement, without requiring any further intervention from an operator, facilitates the complete emptying of the container's contents into the skip and the return of the emptied container in a clean state.
[0021] According to one aspect, the invention also relates to a collection vehicle comprising: - a vehicle chassis; - a toggle switch arrangement as described above, and - a liquid reservoir in fluidic connection with a cleaning tool allowing the liquid to be sprayed, the reservoir being attached to the skip, the cleaning tool being able to spray the liquid over the recess, over an axis allowing the supporting structure to pivot beyond the upper edge; in which the skip carries the cleaning tool as well as a control interface to control the tipper and operate the cleaning tool.
[0022] According to another aspect, it is proposed to use the tilting arrangement, in order to lift and tilt a container, use in which the supporting structure is moved following a sequence which includes 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 a hinged connection on top of the fixing part; - after engaging a container on the supporting structure using the gripping device, lifting of an articulation axis around which the supporting structure can pivot, by one or more lifting actuators; - tilting of the support structure with the container held by the gripping member, by rotation around the joint tax, until an overlap is obtained between: a plate forming one end of the support 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 implementation methods
[0024] Several non-limiting examples of embodiments are set out in detail below. In the various figures, identical reference numerals indicate identical or similar elements. Throughout this application, and as can be seen in the embodiment examples in Figures 1 to 5 and 7, the Z direction designates the vertical direction of the space, while the skip 2 is extended in a horizontal direction.
[0025] With reference to Figures 1 and 2, the tipper 1 is configured to discharge the contents of a container 10, mounted on a collection tank portion designed to receive these contents. With reference to Figure 1 in particular, a skip 2 is provided to form such a collection tank portion. The skip 2 has two parallel side walls 200, 200', which can delimit a significant internal volume V, for example, exceeding one or more tens of cubic meters. The side walls 200, 200', with a front wall end 21 and a rear portion 22 that can be equipped with at least one lockable door, allow the materials and components discharged into the internal volume V to be retained. The door of the rear portion 22 can be hinged, if necessary, for example, around a horizontal axis when the door is made as a single pivoting unit.When the skip 2 is suitable for being separated from the truck (before or after each loading cycle, typically), for example by forming a "tipper" skip, the front wall end 21 may include a maneuvering grip 2b accessible from the outside. Each side wall 200, 200' extends upwards from a bottom 2a. The tipper body 2 may optionally have a reinforcing top band. More generally, it is formed by the 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 internal volume V is locally reduced on the side of the side wall 200, for example in an area distant from the rear part 22.
[0026] By choosing a "tilting" skip, it is possible to easily tilt the skip 2 by raising the end of the front wall 21 where the operating handle 2b is located. This allows, if necessary, for a portion of the collected waste to be moved from the front to the rear within the interior volume. Alternatively or in addition, a movable floor and / or transfer means mounted on a base 2a of the skip 2 can also be used to move a portion of the collected waste to the rear, thus freeing up more space (in volume V) at the front where a container is discharged. 10 operated using the tipper 1. The bottom or base 2a may constitute or include a load-bearing floor. The tipper 2, when of the "ampirole" type, may include one or more rollers r2 arranged on a rear side, two lower reinforcing and guiding slides Gl, G2.
[0027] The tipper 1 is equipped with a container gripping element or part thereof for the container 10, enabling the container 10 to be locked, for example, by clamping or pinching it against a comb 14 adapted to come 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 emptying (into the skip) is located. The comb 14 or similarly shaped assembly can be moved, for example, lowered and then slid upward relative to the counter-comb 14', so as to hold and lift a container 10 by means of its rim 9.
[0028] The gripping member 1 is part of a supporting structure 5 for lifting and tilting the container 10. This structure 5 is movably mounted on a guide 4 that prevents rotation of the container 10. Thus, for a standard-sized container 10 with a wide opening O, the guide portion 4 helps to linearly guide the lifting of the structure 5 on which the container 10 remains suspended. For example, the guide portion 4 includes two parallel rails 4a, 4b, each extending between a lower end located in the lower zone of the recess 2c and an upper end located in an upper opening zone of the recess or near the top of the recess. An intermediate part of the tilter 1, for example, movable only by sliding relative to the guide portion 4, is guided in these rails 4a, 4b.As detailed later, the load-bearing structure 5 can be rotationally coupled 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 in Figures 2 and 3C, is then movable by sliding while allowing the load-bearing structure 5 to pivot. The pivoting mounting of the structure 5 can be achieved by supporting the structure 5: . - on the one hand, by actuators, for example VB tilting cylinders 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.
[0029] More broadly, it is understood that the supporting structure 5 is mobile around a pivoting axis A which is vertically adjustable along the guide section 4. The tipper arrangement 100 may have actuators or means for disengaging and lowering the structure, operating independently of the actuators or lifting means ML. Thus, in the recess 2c, lowering means MA are provided to lower the gripping member 1 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 tipper 1 compatible with a configuration of the skip 2 mounted on the chassis of a truck 60 or collection vehicle. In such a case, the supporting structure 5 in the retracted position (in this first position) can typically be higher than this lowered position.The component and, more generally, the essential part of the load-bearing structure 5, extend above a base 2a of the skip 2 to allow the arrangement 100 to be compact. Example(s) of toggle switch integration
[0030] With reference to figures 1, 2 and 4-5, the tipper 1 can be carried by the skip 2 by being fixed in the recess 2c, so as to occupy a substantially parallelepiped volume, for example with a height H1 of the tipper 1 which can be substantially equal to the height h2 of the receiving part / reservoir of the skip 2. More broadly, the tipper 1 can be designed and dimensioned to be taller than it is wide, and with a depth limited to less than 55 cm, for example on the order of 40 cm, in a retracted state as seen in particular on [Fig.4]. 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 allow this guide part 4 to be articulated around an axis XI by being connected to the support 3.
[0031] Tilting of this guide portion 4 can be achieved in an area adjacent to or located at the bottom of the recess 2c, by using cylinders VI or similar actuators capable of pushing outwards the lower end E4' of the guide portion 4. In this option, the mounting bracket 3 can be designed to support the guide portion 4 of the rocker 1 both by an upper end, which can carry portions of axes 4r or similar parts of a hinge or articulation (forming the axis XI), and by a lower end with the actuator(s) / cylinder(s) VL
[0032] The guiding part 4 can thus have a generally inclined orientation corresponding, for example, to the direction D' in the case of [Fig. 4]. This change of orientation also affects the entire supporting structure 5, insofar as This can be mounted movably on the guide part 4 by means of a frame or slide 15 which remains parallel to the guide part 4, for example by being interposed and guided between the two rails 4a, 4b. In this integration example, toggle switch 1 combines: - mobility of the guide section 4 (typically for the initial disengagement of the load-bearing 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 tilt it until its contents are emptied into the internal volume V of the skip 2.
[0033] The actuators, in particular the VL cylinders of the tipper 1 capable of raising the supporting structure 5, can be entirely contained within the recess 2c, for example, by each having a mounting fitting 4c provided on a mounting support 3, allowing the guide section 4 to be secured to the bucket 2. This mounting fitting 4c is compatible with rotation about an axis (which may be a horizontal axis) of each VL cylinder. A crossed arrangement of two VL cylinders may optionally be provided, as illustrated in 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.
[0034] Whatever the design specifically provided for the moving part of the tipper 1, it can be bordered / arranged between two parallel sides of a similar rigid mounting frame or support 3, which remains fixed relative to the skip 2. At least two cross members T3, one lower and one upper, can connect these sides. In the non-limiting case of [Fig.2], a mounting support 3 designed independently and fixedly mounted to the skip 2 is shown, in order to support a guide part 4 which is typically distributed on two sides forming rails 4a, 4b for the sliding of the movable part of the tipper 1. In alternative embodiments, the support can be an integral part of a wall 200 (first side wall) of the skip 2, this support 3 being present / provided for in the design of the skip 2 in this latter case.
[0035] To allow mobility of the supporting structure 5 relative to the mounting bracket 3, a number of cylinders or similar actuators may be provided. As can be seen in particular in Figures 7A and 7B, the actuators may be concealed (not visible in the side view of the skip) when the tipper 1 is in its resting position. A control unit or panel 16 may also be attached to the skip 2, for example on a front side of the recess 2c, near from the front wall end 21 of the skip. A control interface, linked to a cylinder control module, can 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 having remote control functions.
[0036] A sliding intermediate portion or slider 15 and a tilting portion 12 can be coupled together, adopting a parallel (overlapping) initial configuration 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 that partially covers it externally in order to make available a comb 14 facilitating the gripping of a container 10. In order to limit the size of the tipper 1 relative to the dimensions of the skip 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(s), preferably flat (arranged vertically), forming the tilting portion of the supporting structure 5. Example(s) of kinematics of the load-bearing structure
[0037] The supporting structure 5, which can be substantially flat, extends, for example, along a substantially vertical plane in the retracted position, which is a starting position. The gripping member provided in the supporting structure 5 can function without losing the flat conformation of the supporting structure. In advantageous options, the gripping member consists of reliefs formed on an outer face of a lower portion 11 of the structure 5. For example, it is a comb 14 forming a lower part of a jaw of the rocker 1. The lower portion 11 can then be a sliding part mounted along an outer face of another portion 12 of the structure 5, which is capable of rocking to a raised level of the supporting structure 5.In the retracted position, portion 12 acts as a guide for portion 11 and extends higher, including a counter-comb 14' or adapted relief to form a stop for the container 10 when the comb 14 is raised (due to a 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 Tl on [Fig.8] and can, if the container 10 is grasped, be immediately followed by a further rise corresponding to the lifting of the container 10 and the raising of the axis A (rise reflected by the arrow TL).
[0038] The jaw function of the supporting structure 5, which may be optional, allows the container 10 to be easily locked by taking advantage of the selective mobility of the lower portion 11, made possible, for example, by cylinders or similar actuators forming lowering means MA. Lowering of the gripping member 11 may be provided, if necessary after offsetting or disengaging the latter. to allow easier engagement of container 10, in particular if skip 2 is raised, for example by being mounted on a truck chassis 61 (see figures 6 and 7A for example).
[0039] Once the container 10 is 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 in [Fig. 8]) and during a tilting phase (step 54 in [Fig. 8]). The locking of the grip on the container 10 can advantageously be achieved while the container
[0040] In a first embodiment, the rocker 1 is capable of exhibiting three distinct trajectories of movement relative to the fixed mounting support 3, namely: i) before taking hold of a container 10, a trajectory allowing the guide part 4 to be moved relative to the fixing support 3 (which corresponds to a first trajectory of movement, which may consist of a rotation); this allows for clearance in case of lowering of all or part of the supporting structure and / or to disengage at least partially the tipper 1 to facilitate the placement of the container 10 (for example for non-supported / directly ground operation of the skip, without interference with a vehicle chassis); ii) after securing the container 10 with a locking mechanism (by pinching or other holding mechanism), a lifting along a trajectory TL which can be substantially linear, for example by following the extension direction D' of the guide part 4, knowing that the stroke of this trajectory TL can 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 over 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 slider 15, the angle of rotation typically exceeding 100 or 120°, possibly without reaching or exceeding 160 or 170°.
[0041] The lifting applies to an assembly comprising a slide 15 and the supporting structure 5. The slide 15 includes fittings 15c to follow the extension of the cylinders VL or similar active actuators to obtain the displacement of this assembly along the trajectory TL.
[0042] It is understood that trajectories ii) and iii) can be linked sequentially, with the tilting following the lifting. In [Fig. 1], direction D illustrates a non-limiting example of the final inclination that can be obtained for container 10 and the The load-bearing structure 5 (here substantially flat) with which it is engaged. The opening O of the container 10 is thus oriented downwards after tipping, towards the internal volume V. Optionally, with the use of a ramp 24 covering the recess 2c from above, as seen in the example in [Fig. 10], the contents can be emptied into the skip 2. The ramp 24 can form a fluid-tight wall element, allowing liquid exiting through the opening O to flow into the internal volume V. The ramp 24 is optionally wider than the free end 5a of the upper portion 12.
[0043] In the tilted position, 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 and 12 being maintained). The upper portion 12 may have an extension 12c, located beyond a point of attachment to a shaft or axis element(s) that defines the pivot axis A, so that this extension 12c is located higher and directly above the recess in the tilted position of the supporting structure 5, as can be seen in particular in [Fig. 10]. The extension 12c may be located above (entirely above) the gripping member 1 in the retracted position.In the tilted position, an overlap can be achieved 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.
[0044] This ramp 24 can be either stationary and inclined (downwards), up to a tipping edge 24b, with an angle of inclination A5 similar to that of the structure 5 in the tilted state, or mobile to reach this inclined position in response to an actuation of a drive element, for example by exerting a downward push 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°.
[0045] This type of movement of the supporting structure 5 can be implemented both in the case of [Fig.7A], with the skip on the chassis 61 of a truck 60, and in the case of [Fig.7B] when the skip 2 has been placed on a collection site allowing the truck 60 to carry out other transport operations. When the skip 2 rests on a chassis 61, not only is the supporting structure 5 mobile by lifting and tilting relative to the support 3, but the guide part 4 can also pivot, for example by being pivoted slightly in the recess 2c to bring the lower end E4' of the guide part 4 out of the recess 2c, for example as described above using jacks VI which, in a retracted state, can typically have a length 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.
[0046] With reference to [Fig. 2], the direction D' reflects, for example, an inclination of the guide portion 4 that supports the load-bearing structure 5, by rotation around an angle that 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 load-bearing structure 5, in order to make the gripping member accessible outside the recess 2c and, for example, allowing this gripping member to be lowered if necessary, taking into account any (vertical) offset of the recess 2c relative to the ground. This can be achieved with a linear lowering path (along the direction D', for example) passing close to the chassis but without interfering with it. The offset of the guide section 4 can be limited, and the rocker 1 can be designed without articulated arm(s) that might create an inconvenient bulk and / or operating difficulties. As measured along a radial direction (perpendicular to the lateral face FL of the first wall 200), the lower end E4' of the guide section 4 can be offset by less than 40 cm, for example, less than 30 cm. By designing the supporting structure 5 to be flat, this effectively limits the offset of the gripping element (which does not deviate too far from the recess 2c).
[0047] Such a displacement of the guide portion 4 around the axis XI amounts to pre-positioning the supporting structure 5 along the direction D' ([Fig. 2]), which is the guidance direction (see the inclination of the guide portion 4, which can be generally shallower than the recess 2c in the initial / undeployed configuration of the rocker 1), both during lowering and lifting. This type of pre-positioning can correspond to an operating mode reflecting the case of [Fig. 7A] or similar.
[0048] The inclination of the guide part 4, which supports the load-bearing structure 5, is obtained by rotation around the axis XI 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 lifting cylinders or actuators VL can also be located further back (further towards the bottom) from the guide part 4, optionally by being supported by a lower portion of the guide part 4 which protrudes towards the bottom from rails 4a, 4b or similar guide uprights. The movement of the guide section 4 can be actuated opposite the end E4 where the axis XI is located, as shown in particular in [Fig. 4], and can limit the offset or disengagement to a lower part of the supporting structure 5 and / or avoid the subsequent need for 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 container 10 to approximately the same level as the upper edge 2d. Non-limiting example of assembly and design of the load-bearing structure
[0049] With reference to [Fig. 2], the mounting support 3 can form one or more bearings 8 that contribute to supporting a frame or assembly with two rails 4a, 4b forming the guide portion 4 of the rocker 1. The guide portion 4 constitutes a mounting portion for carrying / supporting: - the lifting means, here in the form of VL lifting jacks or actuators; and - a sliding assembly including the slide 15 (possibly made from a single rigid block, as seen in [Fig.3C]) and the tilting device which constitutes the load-bearing structure 5 and allows the container 10 to be grasped. In the illustrated cases, the supporting structure 5 consists primarily of two plates or portions 11, 12, with the lower portion 11 assembled as a partial cover plate for the upper portion 12, by overlapping a lower region of the upper portion 12. The slide 15 may be provided with two internally arranged side flanges along the rails 4a, 4b of the guide section 4. A cylindrical section, forming the pivot for rotation about axis A, is provided within the slide 15, extending from one of the two flanges to the other, for example, by being joined to their respective upper ends. The cylindrical section or shaft 15a helps maintain an arrangement of the supporting structure 5 which, in its retracted configuration, is parallel to the rails 4a, 4b.
[0050] The lower portion 11 can be mounted to slide relative to the upper portion 12 of the structure 5, with the lower portion 11 optionally guided between two wings 18 with return or lateral guides provided on the upper portion 12. A plate design can be adopted for at least one of the two portions 11, 12, so as to limit the depth (in the recess) of the supporting structure 5. The lower portion 11 can overlap the upper portion 12, parallel to it, on the outside when the lateral guides / wings 18 are formed projecting outwards from the rest of the plate constituting the upper portion 12. The lowering of a comb 14 or similar gripping area of the structure 5 can, in preferred options, be activated once the inclination of the guide part 4 has been obtained, which allows, where appropriate, bypassing of inset barriers 62, visible on the [Fig.7A], and / or another part of the chassis 61.
[0051] As can be seen in particular in Figures 7A-7B, the upper portion 12 includes a spillway sub-portion formed by the extension 12c which extends above the counter-comb 14' in the retracted position of the supporting structure 5. During tipping, the contents of the container 10 can slide over the extension 12c forming This discharge sub-section. The lower portion 11, arranged as a comb holder, may include an insertion end El 1 (formed higher than the comb 14) suitable for insertion under the extension 12c, the upper portion 12 delimiting, typically under the extension 12c, a sliding passage for the lower portion, this passage being 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 Eli. In some options, the shape or perimeter of the lower portion 11 may generally be rectangular.The lower portion 11 and the upper portion 12 can form a tilting 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.
[0052] In one embodiment, the extension 12c may define a recess and / or be offset outwards relative to the rest of the upper portion 12, so as to cover the insertion end El 1 provided in the lower portion 11. It is understood that the extension 12c may be designed to extend, at least partially, 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 the tilting cylinders VB, as in the case illustrated in [Fig. 2]. More generally, the lifting force FL may result from the actuation of any thrust / lifting element that is installed in the recess 2c: - between face F2 (the face visible in particular on [Fig.5]) of the delimitation of this recess 2c, - and the supporting structure 5 (with such organs located at the rear of it as clearly apparent on [Fig.7A]).
[0053] In some 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 out of the recess 2c.
[0054] With reference to [Fig. 3A], 3B, 4 and 7A, the supporting structure 5 can be coupled to a slide 15, the coupling of which to the guide portion 4 prevents it from rotating about the axis A, which can be formed by the shaft 15a of this slide 15. Relative to the structure 5, the slide 15 is positioned 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, relative to an external face of the guide portion 4. This structure 5 may have a shallow 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 in relation to the slide 15, in the retracted position.
[0055] 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 than the position of the receivers or bearings 12 for the articulated coupling of the supporting structure 5. It is understood that the cylinder(s) VB form actuating elements for a pivoting of the supporting structure 5 beyond said upper lateral edge 2d, being activated only for a raised position as shown in [Fig.2].The VB cylinder(s) are here supported by the slide 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 slide 15 exiting the recess 2c.
[0056] With reference now to [Fig. 1] or 5, it can be seen that the recess 2c only moderately reduces the width of the skip 2, for example without the depth L1 or that of the recess 2c exceeding 25 or 30% of the nominal width of the internal 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). Depending on the direction of the length of the skip 2, the extension of the recess 2c can be limited to less than 2 meters, possibly less than 1.6 meters. In [Fig.7B], for example, we see that the recess 2c can, along the wall 200, be delimited between two edges with a spacing dl which represents less than 30% or 35% of the total length of the skip 2, without intersecting / interfering with the rear half Va of the internal volume V. Combination of a tipper and a cleaning tool carried by the skip
[0057] The tipper 1 can be associated with a cleaning device or tool 7 which is mounted on the skip 2, so as to be able to direct one or more jets of liquid spray into the container 10 via the opening O when the latter is in the tipped position, above the upper side edge 2d. Optionally, side walls 200, 200' and possibly the front wall end 12 can be provided with spray bars 17 or similar liquid spraying devices for cleaning and / or rinsing the skip from the inside. The cleaning tool 7 can be integrated on a front side of the skip, for example without extending onto the side of the rear half Va of the internal volume V.
[0058] The skip 2 can carry a liquid tank T in connection with the cleaning tool 7 and, where applicable, with the spray booms 17. The tank T can be located in the internal volume V, offset forward from the discharge area ZD. While the tank T extends essentially or entirely under the upper edge of the skip 2, the cleaning tool 7 can be carried by the skip 2 and mounted in a movable position so as to be able to move on top of the skip 2, typically above the internal volume V so as not to interfere with the discharge permitted by the tipper 1.
[0059] In the non-limiting case of Figures 1 and 5, a frame having two sides Cl, C2 is arranged transversely on the skip 2, being fixed both to the top of the first wall 200 and to the top of the second wall 200'. The attachment to the first wall 200 can be made on either side of the upper end of the guide portion 4. The spacing between the two sides Cl, C2 can correspond to a wide area including the ZD unloading zone for the contents of the container 10. In alternative embodiments, a frame of the cleaning tool 7 can be arranged only on one side relative to the ZD unloading zone for the contents of the container 10 and / or only opposite the recess 2c, without being attached to the first wall 200.
[0060] The chassis Cl, C2, or similar mounting support can extend cantilevered over the skip 2, in particular from an upper edge 2g of the skip that is opposite the edge defined above the recess 2c, so that the cleaning tool 7 occupies a recessed position by default, being arranged at a distance from the upper edge 2d. This tool 7 can have one or more movable cleaning head(s) 7a. In practice, the movable head 7a is movable relative to the mounting support or chassis, being able to be brought closer to / moved towards the upper edge 2d of the first wall 200.
[0061] 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 over the upper edge 2 in a direction D7 away from the upper edge 2g (second edge) provided on the wall 200'. A liquid pressurization pump may be provided in the circuit supplying the liquid to the cleaning head 7a. In the retracted position, the tool 7 can be oriented differently, possibly with the head 7 closer to the second edge 2g than to the first upper edge 2d where the pouring takes place. The retracted configuration is thus distal to the first upper edge 2d, with, for example, a tool spacing 7 at least half the width of the skip relative to the pivot axis A.
[0062] An activation, via the control unit 16, can coordinate the movement of a cylinder VN or cylinder assembly to obtain an inclined position of the cleaning head 7a, which can extend to the extended position (maximum or with a further possibility of extension via the movement F7 if the cleaning head 7a has a telescopic design). As soon as the cylinder of the cylinder VN is extended to the maximum position, a controller of the unit 16 can adjust / activate the pump to begin the spraying operation.
[0063] The cleaning configuration can be obtained by controlling a suitable actuator, for example at least one cylinder VN (visible in particular in [Fig. 5]), which is, for example, started when the rocker 1 is in a tilted configuration that allows the opening O of the container 10 (grasped and lifted by the rocker) to be oriented both towards the inner volume V and opposite the second edge 2g. In the cleaning configuration, the tool 7 can have an elongation axis D7 which coincides with or is substantially parallel to: - to the direction of a central axis the container 10 passing through the opening O; - and / or to the direction of inclination of the supporting structure 5 in the tilted state.
[0064] Typically, in the cleaning configuration, due to the deployment of the tool 7, the cleaning head 7a can be closer to the edge 2d than to the opposite edge 2g, by being positioned in the spill zone ZD or higher and directly above this spill zone. [Fig. 10] shows an example of positioning the cleaning tool 7 made possible by a rotational movement that tends to lift the cleaning head 7a. This lifting may involve a rotation with straightening of the tool 7 and then possibly a lowering of the tool until the extension axis X7 of the tool 7 is oriented towards the interior of the container 10, which is cantilevered by the tilter 1). In [Fig. 1] or 5, it can be seen that the support frame 6 or equivalent mobile support, on which the cleaning head 7a is fixed, is hinged to the fixed chassis C1, C2.This arrangement allows the cleaning tool 7 to be stored flat, with the chassis Cl, C2 substantially horizontal, using a simple rotation kinematic system that can limit the rotation angle (to less than 180°, for example less than 150°) of the support frame 6 to achieve the cleaning configuration. The upper travel of the support frame 6 is compatible with a skip 2 having a significant loading height, for example, considerably exceeding half the skip height.
[0065] Alternatively, as shown in [Fig. 9], a sliding movement can be actuated along a substantially horizontal guide, here for example a rail element R, which is mounted on top of the skip 2, by means of a support The SM mounting bracket (carrying the tool 7) is capable of sliding along a transverse direction perpendicular to the longitudinal extension of the bucket 2. The SM mounting bracket is configured to slide and, simultaneously, rise into a more upright position, extending along an inclined orientation in a direction similar to that (direction D7) shown in [Fig. 10]. A sliding linkage 7c of the SM bracket, optionally using a roller, rack, or similar mechanism, can be combined with pivoting linkage parts 70, 72, attached to the SM bracket on which the tool 7 is mounted.In response to the extension of one or more cylinder(s) VN towards the edge 2d, here to rotate upwards the connecting arm(s) 72 which is / are jointly connected to the guide without sliding capability, the entire support SM is pulled towards the edge 2d while further tilting the tool 7 due to the rotation of the support SM around a movable axis A7 (movable along the rail element R in the case of [Fig.9]) coinciding with the roller or similar sliding element.
[0066] Regardless of the specific design option chosen, the cleaning tool 7 can be brought close to the edge 2d by means of a support or frame 6 or SM, optionally with the possibility of actuating a telescopic movement (see arrow F7 in [Fig. 1]) of the cleaning head 7a when it is already in its operational orientation for liquid spraying. This arrangement, with a telescopic mounting of the cleaning head, movable relative to a body that may be tubular, allows the cleaning head 7a to be brought closer (or its approach accelerated) to a bottom area of the container 10 whose contents have just been emptied.More generally, the cleaning tool may feature a selectively movable cleaning head design, preferably so as to allow it to extend over / in line with the recess or similar area of integration of the tilter (or even beyond such an area), typically to fit inside a container 10 which is tilted.
[0067] In the illustrated options, the cleaning head 7a is capable of pivoting, for example by being made rotationally movable relative to its mounting support SM, 6, so that it can be angularly deflected from the operational direction for liquid spraying. The ability to deflect / move the cleaning tool 7 by more than 90° between the retracted and cleaning configurations can facilitate tool assembly. Example of moving a container
[0068] A case is first described with the tipper 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 device 1 gripping too far from the plane P of the wall 200 where the rocker 1 is located. The container 10 is previously opened, by moving the lid into a folded position against one side of the container 10 which is typically the one opposite to the side engaged by the gripping member 1.
[0069] As shown in 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 out of the gauge of the skip 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 area on a container 10, on one side of the skip 2, for example without lateral gap d (cf. [Fig.6]) greater than 40 or 50 mm between the container 10 and the plane P of the corresponding lateral face FL of the skip 2, when the lower portion 11 is lowered, which corresponds to a step 52 on the [Fig.8].
[0070] When the lower portion 11 is above (again above in the case of prior lowering) the base or bottom portion 2a of the skip, it is understood that the container 10 lifted by the structure 5 remains held close to the face FL. The mounting of the structure 5 can be adapted so that the container 10 gradually approaches the face FL at the beginning of the lifting, optionally without the container 10 entering the recess 2c (which is already occupied by the actuators V2, VL, VB).
[0071] Lowering step 52 may be conditional upon the completion of a step 51. Prior to changing the orientation of the guide portion 4. The lowering means MA may include actuators specifically mounted on the support structure 5, in an upper portion 12 thereof, so as to be able to selectively lower the lower portion 11, without displacement of any other component of the rocker 1. The lower portion 11 may include, near its lower edge and in an area that does not overlap with the portion 12, mounting lugs 1 Ip for the respective connection at one end, for example, a cylinder head, of the actuators / cylinders V2. As shown in [Fig. 2], such lugs 1 Ip may project inwards / rearwards to allow connection from the rear of the portion 11 to cylinders 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 V2 cylinders, which are carried by the upper portion 12 via fixing fittings 12f, can extend essentially to the rear of the upper portion 12, protruding below for attachment to the portion 11 with the ability to extend downwards to obtain the selective lowering of the lower portion 11.
[0072] Prior to the lowering of the lower portion 11 or similar comb-carrying portion, as illustrated in [Fig. 4] or 8, the guide portion 4 may be slightly inclined with respect to the vertical in the initial orientation change step 51, subsequently remaining fixed in such an inclined position without the ability to rotate. Alternatively, as in the case illustrated in [Fig. 4], the guide portion 4 may rotate slightly from an initial vertical position in order to combine optimal embedding in the recess 2c (in vertical configuration) and the ability to lower the lower portion 11 without rotation, bypassing the truck chassis 61 (the recess 2c being located directly above a portion of the chassis 61, as illustrated in Figures 6 and 7A).
[0073] A lifting phase of the lower portion 11 may then be required to secure and lock the container 10. As can be seen in particular in [Fig. 8], the lifting means V2, VL (here with hydraulic cylinders or similar actuators) can enable a lifting step 53, which can be broken down into: - a first trajectory movement Tl, during which the cylinders V2 rise with the lower portion 11 to turn the comb 14 or similar gripping reliefs closer to the counter-comb 14' or similar stop part provided on the upper portion 12 (which allows the container to be blocked / locked in the gripping position); then - a second TL trajectory movement, possibly without deviation of the overall ascent trajectory knowing that the guidance part 4 can remain fixed at this stage.
[0074] Figures 2 and 4 show a sliding assembly of the supporting structure 5 using rails 4a, 4b belonging to a guide section 4 which extends over most or all of the height of the recess 2c, possibly even extending above by an additional height hl to allow for articulated mounting of the guide section, via bearings 8 or similar mounting sections provided on either side of an upper opening of the recess 2c, along face FL. Thanks to this arrangement, the container 10 can remain particularly stable, without any pivoting, during a lifting phase corresponding to the sum of the trajectory Tl and the trajectory TL, during lifting step 53.
[0075] The supporting structure 5 can thus be lifted without rotation relative to the guide section, if necessary after pushing back the bottom of the guide section 4 via the actuators VI (see also arrow Fl in [Fig. 4]), to slightly tilt the section 4 by a rotational movement around the axis XI defined by the pivot joint in the bearings 8. Such actuators VI can be fixed directly to a lower portion of the side wall 20 or to the support 3, in a mounting area RF which is located, for example, under the guide section 4 and is distributed on two sides. The mounting area RF is, for example, distributed on either side of the rails 4a, 4b or along a equivalent assembly which (just like the arrangement of rails 4a, 7b) does not interfere with the lowering or lifting of the supporting structure 5.
[0076] With reference to Figures 1, 5, and 7B, the movement of the container 10 can be carried out similarly for a skip 2 whose base 2a, delimiting the internal volume V, is very close to the ground, for example, separated from the ground only by rails Gl, G2, or without resting on a separate frame 61. In this case, which corresponds to a second operating mode, at least one of 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. This simply requires choosing a low resting height for the comb 14 (for example, on the order of 1 meter or less) that is compatible with gripping the lip 9 from below, the lip 9 of which is generally standard in height and typically between 1100 and approximately 1300 mm.In variants, arrangement 100 can be configured to operate only in an operating mode without lowering the gripping element below the base level of the skip 2. This can simplify the tipper 1 while benefiting from an optimized footprint when transporting the skip 2.
[0077] As can be seen in particular in [Fig. 5], the tipper 1 operates without any actuator involved in lifting and tipping the container 10 extending over or to the sides of the container 10, which makes this operation safe for the operator. If necessary, a support or control optimizing the operator's safety may be required to force the operator to move away from the container, for example, typically by positioning themselves facing the control unit 16, thus avoiding being in the movement zone of the structure 5 and the container 10 being unloaded.
[0078] The tipper arrangement 100 can be obtained with a modular design, for example with components designed separately from the skip 2, the only peculiarity of which may be to have a recess 2c of width and depth corresponding to the dimensions of the tipper 1. Where appropriate, a tilting floor mechanism and / or a scraping device, for example to move contents of the skip 2 towards the rear, may be provided. Furthermore, skip 2 can be made shorter or longer, with the possibility of adding an extension to the skip, for example on the rear side, if you wish to increase the storage capacity.
[0079] The tipper arrangement 100 provides a retracted position of the support structure 5, with a height level (at rest) of the gripping member that is compatible with placing the skip 2 on the ground, thus without any part projecting downwards relative to the underside of the skip. With the support structure 5 thus positioned higher than or above a base 2a of the skip 2, the presence of means MA lowering allows this arrangement 100 to be compatible with the first operating mode of the tipper 1 compatible with the tipper 2 mounted on a chassis of the truck 60, while also being able to operate according to the second operating mode, without lowering.
[0080] The control of actuators VI, V2, VL, VB and the cleaning system (via at least one actuator or cylinder VN and a liquid delivery device for spraying) can be carried out via an automatic control unit 16, typically compatible with an emergency stop control. Such a control unit 16 can automatically perform a relative movement of the washing / cleaning head 7a according to at least one washing cycle comprising a programmed sequence of movement steps. More broadly, for efficient cleaning, the control unit 16 may be equipped with an automatic detection system associated with a cylinder VN or other component representing the actual movement of the head 7a and / or the tilted position of the container 10. This detection system is thus capable of automatically detecting that the head 7a (for example, tilted into the discharge zone ZD) and the container 10 (tilted) or the supporting structure 5 that holds it are in the desired positions.
[0081] A delay before the cleaning is activated may be provided to ensure that the contents of the container 10 have been discharged.Optionally, the movement of the mobile frame or support 6, SM can be integrated into such a timing system to allow a rapid sequence between the tilting phase, the unloading time, and the start of spray cleaning, thanks to the cleaning head(s) 7a held cantilevered above the internal volume V.
[0082] The cleaning head(s) 7a clean the inner wall of the container 10, which may be a waste bin, a recycling bin, or similar. Once the cleaning is complete, in accordance with the program of the controller / control unit 16, the water / liquid pump can be shut off. The telescopic cylinder, if present, is adjusted to retract each cleaning head 7a, and then the tilting cylinder of the actuator VN is retracted. The cleaning operation is complete, and the container 10 returns to its starting position near the bottom of the recess 2c. The jaw can be loosened to disengage the container from the similar gripping device, for example, by lifting it relative to the comb 14.
[0083] With reference to [Fig. 6], 7A and 7B, a collection vehicle 60, such as a truck, can integrate the tipper assembly 100 and the cleaning system, possibly without any direct modification to the truck body. It is understood that, when the tipper body 2 carries the tipper components 1 and the control unit 16 (where applicable with the associated power supply(s)), neither the chassis 61 of the no truck or other vehicle parts are required to control the tipper 1. The tipper 1 and the cleaning system can be controlled by a control unit 16 which activates, for example, the lifting to first raise the slide 15 or similar non-tilting part of the tipper 1, before actuating a relative pivoting of the support structure 5 with respect to the slide 15. Such a collection vehicle 60 can for example be a heavy goods vehicle used for waste collection, intended to transport the skip 2 which can receive waste or materials to be recovered which are stored in containers 10.
[0084] The sequence of movements can be programmed according to a sequence that avoids prematurely rotating the support structure 5, particularly when the pivot axis A has not been sufficiently moved to reach or exceed the upper lateral edge 2d of the skip 2 at which and / or above the discharge zone ZD extends. An associated control interface, linked to the control unit 16, for example an HMI (human-machine interface), allows the tipper 1 to be controlled and the cleaning tool 7 to be operated in an intermediate phase between a lifting and tipping step (of the support structure 5) and a return-to-the-ground step of the container involving rotation and lowering of the support structure 5.
[0085] The advantages described above concerning the tipper 1 arrangement 100 also apply to a collection vehicle 60, for example a truck, equipped with such an arrangement 100. Regarding 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 internal volume V of the skip 2. Where applicable, the cleaning system is modular, with some components removably attached to the skip 2 so that it can, if necessary, operate with the tipper in a self-contained skip configuration. For example, the cleaning tool 7 and / or the associated tank T can be removably mounted on the skip 2, possibly with only the tank T positioned within the internal compartment V.
[0086] It should be obvious to those skilled in the art that the present invention allows for embodiments in many other specific forms without departing from the field of application of the invention as claimed. For example, although the case of a tipper 2 of the "ampirole" type being loaded onto a truck 60 equipped with a specific lifting tool to allow the tipper to be moved by engaging the control handle 2b has been illustrated, other types of mechanisms can be used for moving the tipper 2 and / or the vehicle may consist of another transport vehicle, for example a boat (barge, cargo ship or similar) or a suitable rolling vehicle.
