Definitions

  • the present invention relates to a device for weighing rubbish-collecting bins, comprising: at least one lifting arm having a first end oscillatably in engagement with a bearing structure; a hooking element disposed at a second end of said lifting arm and having a rest seating for a lifting pin carried by a bin.
  • Such an automatic gripping and emptying device for rubbish bins is described in the European Patent EP 776835 in the name of the same Applicant.
  • This device essentially comprises a pair of lifting arms parallel to each other, each having a first end rotatably linked to a bearing structure, and a second end carrying a gripping member arranged to engage a bin at a lifting pin laterally projecting from said bin.
  • Appropriate actuating means activated by fluid-operated cylinders carry out the simultaneous displacement of the lifting arms between a rest condition in which they are substantially oriented downwardly and contained in the overall dimensions of the vehicle, and an overturned position in which they are substantially oriented upwardly.
  • a grip position in which the arms bring the respective gripping members completely level with the bin-lifting pins to enable the bins to be picked up from the ground and lifted until reaching of the overturned condition in which the bin is turned upside down over a loading hopper associated with the motor-vehicle.
  • each load cell in an engagement seat suitably defined along each of the lifting arms.
  • the engagement seat of each load cell is arranged at an interruption point of the longitudinal extension of the lifting arm, formed halfway on the arm length, so as to divide said arm into a first and a second portions.
  • the first and second portions terminate at the first and second ends respectively of the lifting arm and are mechanically interconnected by the stiff body of the load cell.
  • the Applicant has perceived that in the embodiments of the above described type presently adopted, positioning of the load cell at an intermediate point of the lifting-arm development involves many drawbacks.
  • a positioning spaced apart from the load cell relative to the application point of the bin load causes transmission of high loads to the cell itself and the structural parts dedicated to its connection to the arm portions. All these parts are therefore required to be conveniently sized in order to support the high loads applied thereto, which will bring about an increase in the weight, costs and structural complexity of the assembly.
  • these circumstances make it economically inconvenient to make devices having arms set to receive the load cells in all cases in which a weighing function, and therefore the presence of the load cells themselves, is not required.
  • use of arms of one piece construction is preferred and consequently drastic modifications to the lifting device will be compulsorily required when the user asks for the installation of the weighing device after some time.
  • an object of the present invention to provide an automatic lifting and emptying device for rubbish-collecting bins, characterized in that said hooking element is disposed on the second end of the lifting arm, being removably in engagement therewith.
  • a device for automatic lifting and emptying of bins for rubbish collection in accordance with the present invention has been generally identified by reference numeral 1.
  • device 1 lends itself to be mounted on a side of a truck (not shown) or other motor-vehicle used for rubbish collection and transportation to the rubbish dumps or other disposal places. To this aim, device 1 has a bearing framework 2 in engagement on the motor-vehicle side.
  • a pair of lifting arms 3 each having a first end 3a oscillatably connected with the bearing structure itself and a second end 3b carrying a gripping and handling member 4 for a bin 5 diagrammatically and only partly shown.
  • each gripping and handling member 4 is provided to be equipped with a hooking element 6 having a rest seating 6a with an arched profile the shape of which substantially matches that of a lifting pin 5a projecting from the side wall of bin 5.
  • Said rest seating 6 is adapted to receive the lifting pin 5a to cause engagement of bin 5 and allow lifting of same by arms 3 above a loading hopper arranged on said motor-vehicle.
  • auxiliary devices can be also associated such as an overturning lever 7 driven by a first actuator 7a to cause overturning of bin 5 over the hopper, an auxiliary lever system 8 driven by a second actuator 8a to cause opening of the bin lid upon overturning of said bin, as well as a safety device 9 to be driven by a third actuator 9a to prevent accidental disengagements of pin 5a from the rest seating 6a during lifting and overturning of bin 5.
  • overturning member 7, auxiliary lever system 8 and safety device 9 are diagrammatically shown and they are not further described as they are not of importance to the aims of the present invention.
  • each lifting arm 3 can be essentially defined, at least at its second end 3b, by a pair of holding plates 10 disposed in mutual and parallel side by side relationship, so that at least part of said auxiliary devices 7, 8, 9 associated with the gripping member 4 can be housed in a space defined between the holding plates.
  • housed in the space defined between plates 10 is the overturning member 7 with the first actuator 7a and the safety device 9 with the respective third actuator 9a.
  • An attachment base 11 is fastened between the holding plates 10 and it is preferably made up of a plate-like element disposed in a plane perpendicular to the holding plates 10.
  • the hooking element 6 Removably fastened to the attachment base 11 is the hooking element 6.
  • the hooking element 6 essentially comprises an anchoring portion 12 fastened to the attachment base 11 by first threaded elements 13, and a suspended portion 14 carrying the rest seating 6a.
  • the suspended portion 14 can be formed unitary with the anchoring portion 12, or rigidly engaged with the latter in any manner.
  • the load cell 15 is fastened to the anchoring portion 12 of the hooking element 6. More particularly, the load cell 15 for the purpose has a first portion 15a housed in a first seat 16 defined between the anchoring portion 12 and the attachment base 11, and fastened thereto by one or more of the first threaded elements 13 used to obtain locking of the anchoring portion itself.
  • the suspended portion 14 of the hooking element 6 is made as a distinct part separated from the anchoring portion 12 and is fastened to a second portion 15b of the load cell 15, by one or more second threaded elements 17, for example.
  • each of the holding plates 10 has a perimetric edge that, as better shown in Fig. 3, defines a recess 18 disposed close to the rest seating 6a and extending concentric with the arched profile of the rest seating itself, according to a radius of curvature slightly greater than said seating.
  • the holding plates 10 further extend forming respective end portions 19 mutually connected at the respective upper edges 19a by a connecting plate 20 adapted to define a lead-in surface to facilitate insertion of pin 5 in the rest seating 6a.
  • the present invention achieves important advantages.
  • the present invention enables device 1 to be adapted for execution of the weighing function in a very simple and cheap manner, by merely replacing the hooking element of one piece construction with a hooking element 6 made of two distinct parts associated with the respective load cell 15, without further interventions on the lifting arm 3 being required.
  • the invention enables the load cell to be installed at a distance that just as an indication does not exceed 200 mm, preferably included between 70 and 110 mm, from the rest seating 6a of pin 5a, i.e. at a very close position relative to the technical solutions of the known art.
  • the load cell is submitted to greatly lower stresses than in known embodiments, in which the load cells were spaced apart a distance greater than 500 mm from the rest seating of the pin.
  • the dimensional structure of the members designed for engagement of the load cell 15 is also greatly simplified as compared with the known art, due to the reduced efforts transmitted.
  • Positioning of the load cell 15 at the free end of the lifting arm 3 further ensures greater reliability and accuracy in detecting the bin weight, because reading is not affected by the structural strength of the accessory components applied to arm 3 such as, for example, hydraulic and/or pneumatic pipes interlocked with the actuators 7a, 8a, 9a of the auxiliary devices.
  • the invention improves safety of use in device 1, by eliminating any risk of the bin 5 falling in case of structural yielding of the load cell or other components of the hooking element 6. It should be noted in fact that in case of structural yielding of the load cell 15, the lifting pin 5a of the bin 5 would find a support on the recesses 18 arranged on the upper edges of the holding plates 10, so as to prevent the bin from falling. This circumstance cannot be found in the known art, where breaking of the load cell takes place upon structural yielding of the lifting arm thereby giving rise to falling of the bin to the ground.
