Definitions

  • the present invention relates to a device for emptying rubbish skips onto a motor-vehicle designed to collect refuse, comprising a bearing framework, operatively mounted to said motor-vehicle; a grasping unit designed to removably engage a rubbish skip to be emptied into the motor-vehicle; a lifting unit carrying the grasping unit and selectively activated to bring the rubbish skip from a position in which it rests on the ground to a raised position in which the skip is hung above a charging hopper exhibited by the motor-vehicle; overturning means associated with the lifting unit for rotating the skip about a horizontal axis when said skip is at the raised position.
  • Said motor-vehicles are equipped with appropriate devices by which each rubbish skip is picked up from the ground for being emptied through overturning above a charging hopper arranged on the motor-vehicle, and subsequently laid down to the ground again.
  • a grasping unit is essentially provided and it consists of a pair of hooking elements carried by respective support arms and arranged to engage corresponding engagement pins projecting from the opposed side walls of the skip at a centered position relative to the vertical centre line of the walls themselves.
  • the support arms are connected to a lifting unit enabling a vertical movement of same so as to cause lifting of the skip from the ground, as well as to overturning means operating an angular rotation of the skip about said pins in order to empty the skip contents into a charging hopper arranged in the motor-vehicle.
  • the side-hooking elements disposed at a raised position relative to the skip and spaced apart a greater distance than the width of said skip are lowered so as to be disposed side by side relative to the side walls of the skip until they reach a position below the side grasping pins exhibited by said skip.
  • the support arms are driven close to each other so that the hooking elements move close to the side walls of the skip in order to operatively engage the grasping pins following the subsequent lifting movement aiming to bring the skip to the same level as the charging hopper.
  • the operating means is operated and it causes emptying of the skip; afterwards the skip is laid down to the ground again following a reverse step sequence with respect to the preceding one.
  • the lifting unit and overturning means are made of one or more fluid-operated actuators directly acting on the support arms of the side-hooking elements to simultaneously cause lifting and overturning of the skip by a single rotational movement of the support arms about a pivot axis of same. Provision is also made for devices in which the engagement of the skip for lifting and overturning it is carried out by a grasping element substantially in the form of an upwardly facing shovel designed to be inserted in a seat arranged on the front wall of the skip and substantially in the form of a downwardly open pocket.
  • the skip is engaged at its front wall, there is an advantage as compared to the known art in that the picking up and laying down of the skip can occur even when said skip is located in side by side relation with other skips of the same type.
  • said skips can be disposed side by side thereby reducing the overall surface bulkiness taken up by same.
  • Patent document US-A-3 027 028 discloses a device for emptying rubbish skips according to the preamble of claim 1.
  • a device for emptying rubbish skips onto a motor-vehicle designed to collect municipal refuse according to the present invention has been generally identified by reference numeral 1.
  • the device 1 is mounted to a side of a motor-vehicle 2 designed to collect municipal refuse in order to convey them to the dumps,
  • the device 1 is mounted close to a recess 3a formed sideways in the box 3 of said motor-vehicle, which can be optionally provided with appropriate means for compacting the refuse introduced thereinto through a charging hopper 4 formed in the box itself.
  • the device 1 comprises a bearing framework 5 operatively mounted on the motor-vehicle flatbed.
  • the framework 5, as shown in Fig. 3 is preferentially provided to be slidably engaged to the flatbed 6 and be movable perpendicularly to the longitudinal extension of the motor-vehicle 2 upon command of one or more tranverse-movement actuators 7 or similar means, for the purposes better clarified in the following.
  • a lifting unit 8 Operatively mounted on the bearing framework 5 is a lifting unit 8 in turn carrying a grasping unit 9 designed to removably engage a rubbish skip 10 (Figs. 3, 4, 5), to enable the movement of same from a position in which it rests on the ground to a raised position above the charging hopper 4, upon the action of the lifting unit iself.
  • a grasping unit 9 designed to removably engage a rubbish skip 10 (Figs. 3, 4, 5), to enable the movement of same from a position in which it rests on the ground to a raised position above the charging hopper 4, upon the action of the lifting unit iself.
  • overturning means 11 designed to make the skip 10 rotate about a horizontal axis to cause emptying when the skip is to its raised position above the hopper 4.
  • the grasping unit 9 essentially comprises one or, as shown in the accompanying drawings, a pair of fitting pins 12 preferably disposed aligned in coaxial relation, facing each other, and provided with respective tapering ends 2a.
  • the fitting pins 12 are fastened to respective support arms 13 in the form of a broken line and engaged to a guide structure 14.
  • the guide structure 14 is preferably comprised of a first horizontal guide bar 15, rotatably engaged to the bearing framework 5 and a second guide bar 16 parallel to the first guide bar 15.
  • the support arms 13, slidably passed through by the guide bars 15, 16, are simultaneously movable upon command of at least one double-rod actuator 17 operatively engaged to the guide structure 14 and exhibiting two opposed rods 17 each connected to one of the support arms 13.
  • the double-rod actuator 17, not shown in Figs. 4 and 5 is similar, from an operating point of view, to a pair of opposed fluid-operated actuators parallelly connected in circuit, so that the support arms 13 are simultaneously moved, while remaining mechanically disengaged and independent of each other.
  • the lifting unit 8 involves the presence of at least one lifting lever 20 fastened to the guide structure 14 and engaged to the bearing framework 5 according to a horizontal axis. More particularly, in the embodiment shown provision is made for a pair of lifting levers 20, fastened to the guide bars 15, 16.
  • a lifting actuator (exclusively shown in Fig. 2) operates between the bearing framework 5 and each lifting lever 20 and it is adapted to cause biomass of the guide structure 14 and, as a result, the support arms 13 about the pivot axis of the lifting levers 20, embodied by the geometrical axis of the first guide bar 15.
  • the overturning means 11 exhibits, at a position underlying the alignment axis of the fitting pins 12, at least one locating element 22 designed to act in thrust relation against the front wall 19 of the skip 10 so as to counteract the tendency to rotation of said skip about the pins 12 by effect ot the skip weight.
  • the positioning of the locating element is controlled by a driving mechanism comprising at least one connecting lever 23 pivotally mounted to the bearing framework 5 according to an axis parallel to and spaced apart from the pivot axis of said lifting lever 20, as well as at least one interconnection connecting rod 24 operatively fixed between the connecting lever 23 and lifting lever 20.
  • a driving mechanism comprising at least one connecting lever 23 pivotally mounted to the bearing framework 5 according to an axis parallel to and spaced apart from the pivot axis of said lifting lever 20, as well as at least one interconnection connecting rod 24 operatively fixed between the connecting lever 23 and lifting lever 20.
  • connection between the interconnection connecting rod 24 and lifting lever 20 takes place at the end of an extension portion 20a integral with the lifting lever itself, so that the interconnection connecting rod 24, forms a four-bar linkage together with the lifting lever 20, connecting lever 23 and bearing framework 5.
  • a thrust extension 25 that, by means of at least one overturning actuator 26, is interconnected to an auxiliary arm 27 carrying the locating element 22 at the end thereof.
  • the auxiliary arm 27 is fastened to the interconnection connecting rod 24 at a pivot point on the extension 20a being part of the lifting lever 20.
  • the overturning actuator 26 substantially acts as a connecting rod in order to define, together with the thrust extension 25, the interconnection connecting rod 24 and auxiliary arm 27, a driving mechanism in the form of a deformable articulated quadrilateral imparting the skip a preliminary rotation about the fitting pins 12 substantially through 90° and at all events of smaller amplitude than the rotation carried out by the support arms 13.
  • the overturning actuator 24 lends itself to be operated when the lifted position is reached by the skip 10, in order to transmit a final overturning rotation to the skip, as shown in Fig. 5 where by a broken line it is drawn the position of the skip 10 before its final overturning.
  • auxiliary actuator 28 operatively connected in the extension of the overturning actuator 16 and selectively operable for reducing the width of said premilinary rotation during the skip movement from the position in which it rests on the ground and the raised position.
  • all the component elements relating to said four-bar linkage and deformable articulated quadrilateral are preferably provided in pairs.
  • At least one hooking pin 29 be associated with the locating element 11, which pin is movable, upon command of a respective fluid-operated actuator not shown as known per se and conventional, between an operating position in which it projects sideways from the locating element itself to engage a grip handle 30 fastened to the lower part of the front wall 19 of the skip 10, arid a rest condition in which it is axially retracted inside the locating element 22 to enable free movement of the latter away from and close to the front wall 19.
  • the hooking pin 29 is directed and moves towards a horizontal direction, but it may also move vertically to engage a grip handle oriented horizontally on the front wall 19 of the skip 10.
  • said device During the motor-vehicle running, and at all events under non-use conditions of the device 1, said device has its support arms 13 and auxiliary arm 27 facing downwardly, the pins 12 being substantially at the same height as the tubular seats 18. Under this situation, the device 1 is completely contained within the outline of the motor-vehicle box 3.
  • the motor-vehicle 2 is stopped in register with the skip itself so that the support arms 13 disposed in their maximum opening condition, have a substantially centered position relative to the longitudinal extension of the skip.
  • Suitable sensing means preferably consisting of an ultrasonic distance-measuring detector having an emitting/receiving member 31 located for example on the locating element 22, operate stopping of the side-movement actuator 7 and therefore displacement of the whole device 1 towards the skip 10, when the fitting pins 12 are substantially in alignment with the tubular seats 18 and the locating element 22 is close to the front wall 10 of the skip itself.
  • the engagement of the ultrasonic distance-measuring detector is advantageous in that, unlike it would happen in the case of use of a proximity switch or a mechanical microswitch, such a detector is capable of continuously detecting the distance of the front wall 19 from the skip 10 and therefore operate, if necessary, slowing down of the device movement during the final step of its moving close to the skip, thereby avoiding the contact of the locating element 22 with the front wall 19 taking place with strong shocks.
  • the hooking pin or pins 29 are caused to be axially extracted so that engagement of the locating element 22 with the grip handle or handles 30 arranged on the skip 10 occurs.
  • the driving mechanism 23, 24, 25, 26 and 27 acting on the locating element 22 imparts a preliminary rotation to the skip 10 towards the overturned condition.
  • the amplitude of said preliminary rotation is advantageously reduced as compared to the one performed by the lifting levers 20 and support arms 13, in order to avoid overturning of the skip contents before said skip 10 arrives at a position above the charging hooper 4.
  • operation of the auxiliary actuator 28, if present causes a slight straightening of the skip itself, in order to avoid any risk of early escape of the contents from same and/or shocks of the skip 10 against building walls or other hindrance disposed behind.
  • the auxiliary actuator 28 On reaching the lifted position, the auxiliary actuator 28 is brought back to the starting condition and the overturing actuator 26 is operated in order to obtain a complete rotation of the skip 10 about the fitting pins 12 and the subsequent emptying of the skip to the inside of the charging hopper 4.
  • An inverted operating sequence as compared to the one described above involves laying down of the skip 10 to the ground again, the device 1 coming back to its nonoperating conditions.
  • the invention achieves the intended purposes.
  • the device in reference combines the advantages of practical use typical of known devices provided with a front grip for the skip, with the advantages in terms of safety that can be found in the devices carrying out grasping of the skip at the side walls. It will be recognized that, since the fitting pins 12 are disposed, during the non-use step, at a height substantially corresponding to that of the tubular seat 18, the emptying cycle of the skip takes place in a remarkably shorter period of time than in the devices of the known art, in which the grasping elements are in a raised condition during the non-use steps.
  • the prelimitary rotation transmitted to the skip during the lifting step causes the immediately subsequent overturning step to be obtained through the use of actuators of relatively reduced sizes, as a result both of the fact that a shorter rotation must be covered and that most of the inertia to rotation exhibited by the skip at the beginning of the overturning step has already been overcome.
  • the device in question can be mounted to advantage not only on one side of the vehicle, as in the example herein described, but also, if necessary, on the rear or on the front of the vehicle itself.
