Definitions

  • This invention relates to a device in accordance with the introduction to the main claim.
  • the first compacting member (or first compacting blade) is known to be hinged to one or more actuators, for example hydraulic, which themselves are hinged upperly to the vehicle body.
  • Each hydraulic actuator can rotate about its retaining hinge until its longitudinal axis is in a position inclined to the top of the vehicle body such as to enable the blade to be raised to expose in the vehicle body a usual aperture through which the refuse is loaded into the body, for expulsion therefrom by the movement of a known expulsion plate which expels the refuse.
  • the blade is also hinged directly to the vehicle body in a region distant from that end hinged to the hydraulic actuator.
  • the hydraulic actuator, the first compacting member and the second member associated with this latter and movable with it define a known refuse compactor device within the vehicle body.
  • this device is simple, it has various drawbacks, one of primary importance being the fact that the force exerted by the blades or compacting members on the refuse after its collection within the vehicle body is considerably limited by the direct connection of the first compacting blade to the vehicle body. Because of this connection the action of each actuator, which generates the movement of the first compacting blade (and consequently that of the second blade connected to the first) and which results in compaction of the refuse within the vehicle body is of low efficiency (compared with the power generated by the actuator), the compaction being penalized by the limited arm of the force generated by each actuator on the blade.
  • this arm measured as the distance between the centre of rotation of each blade-actuator system (corresponding to the point at which the blade is connected to the vehicle body) and the line of action of the force generated by the actuator, is reduced during the final travel of the movable part (piston) of the actuator.
  • the thrust which the blade exerts on and transmits to the refuse is only partial, as stated.
  • the volume occupied by the refuse in the vehicle body is hence disproportionate to the actual refuse volume.
  • connection (by hinge) of each actuator to the vehicle body can result in problems related to possible knocking of the actuator against the vehicle body at the hinge, which can also create problems for the action of the compacting blades on the refuse.
  • An object of the present invention is to provide a compactor device associated with a refuse collection vehicle which overcomes the drawbacks of known and analogous devices of the state of the art.
  • a particular object of the invention is to provide a device of the stated type which, for equal installed power, is able to generate a compacting force greater than that generated by analogous known devices of the state of the art.
  • a further object of the invention is to provide a device of the stated type which allows considerable refuse compaction within the body of its collection vehicle, so better utilizing the available vehicle volume.
  • a refuse collection vehicle is indicated overall by 1 and comprises a usual body 2 provided with a refuse collection compartment 3.
  • This compartment is open at 4 at the rear of the vehicle body, to enable refuse to be loaded into it. It is also open at 5 at the roof 6 of the vehicle body 2 to allow movement of a first compacting blade 7 operated by usual actuators (for example hydraulic) 8 positioned on the roof 6 of the vehicle body 2.
  • actuators for example hydraulic
  • Each actuator is hinged at 9 to projections 10 rising from the vehicle body 2 and comprises a usual cylinder 11 (connected to the vehicle body), relative to which there moves a piston 12 the end 13 of which is hinged at 14 to the compacting blade 7.
  • a second compacting blade 16 operated by an actuator (for example hydraulic) 17 hinged in known manner at 18 to the top of the blade 7.
  • an actuator for example hydraulic
  • a cross-member 19 with its axis X perpendicular to the longitudinal axis Y of the vehicle 1 (and hence of the vehicle body 2), which connects the actuators 8 to the first blade (via pins, not shown, rigid with the cross-member (19), and about which this latter is able to rotate.
  • end pins 20 connected to a usual member 21 (for example rollers or the like) movable within guides 22 provided on the body roof 6 in proximity to the body sides 25 and 26 and having their longitudinal axes Z perpendicular to the axis X of the cross-member 19.
  • a usual member 21 for example rollers or the like
  • the first blade 7 comprises two projections 31 hinged to the respective rectilinear arms 32 of a frame 33 hinged at 35 to projections 36 rigid with the vehicle body 2.
  • This frame indirectly connects the first blade 7 to the vehicle body.
  • the frame 33 has a structure comprising crossed arms 38 for mechanical stiffening purposes, and is positioned in correspondence with the aperture 5 in the roof 6 of the vehicle body 2.
  • an expulsion plate 40 having an end 41 associated in known manner with members (not shown) slidable within upper guides 42 (with reference to Figure 4) positioned longitudinally on the sides 25 and 26 of the vehicle body.
  • This plate has its other end 45 associated with a member 46 rigid with wheels 47 slidable along a lower guide 48 which follows the form of the vehicle body 2.
  • This member is subjected to the action of an actuator, preferably hydraulic, hinged at its ends 51 and 52 to the member 46 and to the end wall 53 of the vehicle body 2 respectively.
  • the compactor device is used as follows: on feeding each actuator 8 in any known manner, the members 21 slide in the guides 22, along which there consequently slides the end 30 of the blade 7. Simultaneously with the commencement of movement of said blade the frame 33 rotates about the hinges 35. With these movements the blade 7 rotates about its centre of instantaneous rotation indicated by P in Figure 1. The force generated by the actuator 8 then has an arm indicated by K in Figure 1. As the movement of the blade 7 continues, the centre of instantaneous rotation of the blade (or rather of each system comprising a blade 7 and actuator 8) shifts until at the end of travel it reaches the position indicated by Q in Figure 1. In this case, the force generated by each actuator 8 on the blade 7 presents an arm H greater than the arm K and in any event decidedly greater than the arm of the corresponding force generated by an actuator for moving the first compacting blade in a vehicle with a known compactor device.
  • the actuator 17 When refuse compaction is complete, the actuator 17 is fed and the blade 16 moves relative to the blade 7.
  • the blade 16 moves to retract into this latter (arrow N in Figure 1) and by means of its end part or toe 16A it lifts whatever is present in the compartment 3 towards the roof 6 of the vehicle body 2 to also fill the top of this latter.
  • each actuator 8 is hydraulically retracted into the relative cylinder 11, the members 21 slide in the corresponding guides 22 and the blades 7 and 16 return to the position shown by full lines in Figure 1, but with the blade 16 inserted in the blade 7.
  • the blades 7 and 16 again rotate (arrow E in Figure 1) by virtue of the arms 32 hinged to the blade 7 and to the vehicle body 2.
  • the blade 16 is then extracted (arrow T in Figure 1) from the blade 7 and returns to its initial position for further compaction of the refuse which was fed into the vehicle body 2 when the blades 7 and 16 were in or were moving into their internal position within the compartment 3.
  • each actuator 8 When the compartment 3 of the vehicle body is to be emptied (for example by partially overturning the body in known manner), the piston 12 of each actuator 8 is made to completely retract into the relative cylinder, the blade 7 rising relative to the vehicle body as shown in Figure 4.
  • the actuator 50 is then operated with the result that the expulsion plate 40 passes from the position shown by full lines in Figure 4 to the position shown by dashed lines.
  • the refuse collected by the vehicle body is expelled by the partial overturning of the body and the movement of the plate 40 along the guides 42 and 48.
  • the movements of each actuator 8 and 18 are controlled sequentially for example by a control unit preferably of known microprocessor type, such as to achieve the desired compaction of the refuse within the compartment 3 of the vehicle body 2.
  • Usual control and safety devices (not shown) are provided for correct movement of the blades 7 and 16.
  • This known control unit also controls the refuse expulsion by the expulsion plate 40 and actuator 50.
  • FIGS 5 and 6 show a modified embodiment of the device according to the invention.
  • parts corresponding to those of the already described figures are indicated by the same reference numerals.
  • each end pin 20 of the cross-member 19 is pivoted in a corresponding end 100 of an arm 101 positioned laterally to the vehicle body 2 along its sides 25 and 26 respectively.
  • the arm 101 is hinged to this side at 104 in any known manner.
  • its cylinder 11 rotates about the corresponding hinge 9 which connects it to the relative projections 10 and it separates from the roof 6 of the vehicle body to lie inclined to this latter.
