Definitions

  • the invention relates to an improved device for loading, with compression, different solids in a receptacle. It relates in particular to the loading of materials, in particular garbage or waste, domestic or industrial, into a bucket.
  • the new device is applicable to different containers or dumpsters, fixed or mobile, and - more specifically - to refuse collection vehicles.
  • the devices of the type concerned by the present invention comprise movable means, generally known under the name of shovel or flap, for pushing the materials into the receptacle; these means, mounted in a loading hopper, are driven by motor means placed symmetrically on either side, in the width direction, of the flap.
  • guides were provided for these mobile means of thrust, so as to impose the desired trajectory on the latter, during work. This is the case of US Patent 3,220,586 where the guides have an inclined part and a horizontal, and define the operation of the shutter in a 3-stroke cycle.
  • An improvement was carried out thereafter, according to publication No. 2,436,092 of French patent application: the shutter and its jacks are integral therewith with a sliding beam on a uniformly curved guide, and the operating cycle is at 4 time.
  • the present invention provides significant advantages over the corresponding prior art, both with regard to the construction of the device and the effectiveness thereof.
  • the invention makes it possible, in fact, to load with high compression solids of all kinds, of high hourly tonnage, with a device much lighter than those of known devices; so we can gain, for example, 30% on the weight of the device while treating the same hourly weight of household waste, with an equivalent compression or even stronger than in the past.
  • Another advantage of the device according to the invention lies in the fact that it is possible to load materials into the hopper at any time, during operation, which makes the apparatus appear to continuous devices.
  • the invention gives excellent results in the operation of the loading means with compression according to a 4-stroke cycle, but it can also be applied to work of different rhythm.
  • the mobile means for pushing and compressing the materials to be loaded, consist of two elements, both moving in lateral guides, and articulated to each other, so as to allow their translation along the guides, as well as their reciprocal pivoting.
  • the mounting is such that, during operation, these means move simultaneously, both, in a triangular configuration with respect to the means which produce this movement.
  • Each of the two elements, forming the mobile loading means has a roller in the guide, at its upper end, while the articulation between them is outside the planes passing through the guides, in particular below these plans.
  • this last articulation connects the lower end of the upper element to the body of the lower element between approximately 1/3 and 1/2 of the length of the latter, counted from its upper end.
  • the drive means most often jacks, are, according to the invention, two in number arranged on the lateral sides of the mobile loading elements.
  • the two pairs of drive means are connected to the upper end or head of the lower loading element; one of these pairs has its opposite end connected to the upper end of the upper element, on the guide track, while the opposite end of the second pair of motor means is articulated at the top of the wall of the device, in particular on the hopper door joint.
  • the loading elements are solid panels, the front face of which, that is to say that which faces the interior of the receptacle, preferably has a profile suitable for the pushing and compression work to be carried out.
  • the lower element constitutes a solid panel only in its lower part, below its articulation with the upper element.
  • the top of this lower element is notched, which makes it possible to load the hopper even during the operation of the device.
  • the preferred shape of the lower element is such that the section thereof by a vertical plane, parallel to the plane passing through the guides, is substantially triangular.
  • the upper element it is advantageous that it has a stepped profile, reinforcing this element and helping to retain the treated materials, when the hopper is opened.
  • FIG. 1 shows a set of two loading elements, 1 and 6, moving in the guide 11, with their jacks 4 and 7, all mounted in a class type hopper.
  • sic 9 closed at the top by sidewalls 14.
  • These members are found in all the figures, but are best visible in figure 3. From figure 5 we understand that there is in fact a pair of guides 11, a pair cylinders 4 and one of cylinders 7, and a pair of each of the joints. However, for the simplification of the description, we speak of only one of each of these bodies.
  • the invention has this originality, compared to the known technique, that the two thrust and compression elements, 1 and 6, are articulated to each other outside of the guide 11, at 3, while the two jacks 4 and 7 are both attached to the same joint 2 at the upper end of the element 1.
  • the new structure includes the guide or raceway 11, curved in the embodiment shown, but which may be straight; in this guide, at 5, rolls a roller carried by the upper edge of the movable panel 6, which constitutes the upper element of the compression loading means.
  • the flap 1 has a general U-shape: its active part 1a-1b, which pushes the materials from right to left according to Figures 1,2,3,4,7 and 8 , is carried by two arms 1c and 1'c visible in Figure 6. These arms rotate around the axis 3 which articulates them on the compression element 6; they also pivot around the axes 2,2 ′, on the guides 11, where the jacks 4 and 7 are attached. This results in an empty space 15 above the axis 3, through which materials can be introduced into the hopper, whatever or the position of shutter 1.
  • the active part 1a-1b of the shutter 1 is preferably of a box construction which allows high forces to be exerted by means of a light weight shutter.
  • the height of the arms 1c and 1'c is generally about 0.75 to 4 times that of the active part 1a-1b, and preferably 1 to 3 times.
  • FIG. 7 only the section is shown by the plane YY from the lower end 12 of the part 1b of the shutter, to the axis 3.
  • the section through this plane shows the active part 1a-1b (hatched) of the flap 1, above which is the free space 15, that is to say the notch between the two arms 1c and 1'c; 1 is a wall of the shutter.
  • FIG. 8 being a vertical section of the arm 1'c and of the active parts 1a-1b, by the plane Z-Z, makes it possible to see both the arm 1'c and the part 1a-1b in section (hatched).
  • Figures 1 to 4 are vertical sections through the plane XX of Figure 5, we can see the active part 1a-1b in section (hatched) and the arm 1'c at the end of axis 3 (not hatched) ; however, for the sake of clarity, the references 1a, b, c, 1'c in Figures 6-8 are omitted.
  • the bottom of the panel 6 is articulated in 3 to the flap 1, which gives a compound loading assembly, 1-6, deformable under the action of the associated jacks.
  • the top 5 of the panel 6 is connected to the head 2 of the shutter 1 by a jack 4; the rod 4 'of this jack is articulated at 5 and the cylinder at 2. In this way, as the two ends, 2 and 5, of the jack 4 are located in the path 11, this vee rin always remains aligned parallel to a tangent to path 11.
  • a second cylinder, 7, is mounted between the side 14 of the hopper and the head 2 of the shutter 1.
  • the end of the cylinder 7 is articulated at 8 on the flang of the device, while the rod 7 'of this cylinder is connected to the end upper 2 of flap 1, that is to say at the same point where the bottom of the cylinder of the first jack 4 is articulated.
  • the assembly thus formed of flap 1, panel 6, and jack 4, constitutes a triangle, deformable under the action of jack 4, for each of the positions determined by jack 3, when the latter immobilizes the joint 2.
  • the jacks are preferably hydraulic for a device on a vehicle, but can be electric, especially in a fixed installation.
  • the preferred profile of the flap 1 is substantially a triangle with an obtuse angle at the top 3, and an acute angle at the lower end 12.
  • the obtuse angle is preferably about 100 ° to 125 °, while that of the end 12 measures 10 ° to 35 °.
  • the elements 1 and 6 occupy their highest place on the raceway or guide 11, that is to say that is to say that the rollers of the joints 2 and 5 respectively, are in their highest positions.
  • the jacks 4 and 7 are completely retracted, which means that the flap 1 and the panel 6 are aligned along the guide 11, one in the extension of the other; the angle between 1 and 6 is here the smallest of all that these elements can make between them during work.
  • the situation according to FIG. 1 constitutes the start of the first stage of the operating cycle. This time lies in the expansion of the crushing cylinder 7 which pushes the joint 2 down the path 11. This results in the displacement of the assembly 1-4-6 backwards and downwards, like the indicates the arrow starting from the end 12 in FIG. 1.
  • the first step of the cycle consists in passing the assembly 1-4-6 in the position of FIG. 2, that is to say - say until the arrival of the end 12 of the flap 1 at the bottom of the hopper 9.
  • the inlet of the receptacle 13 is closed by the panel 6 and the flap 1, as shown in FIG. 2
  • due to the special shape of the shutter 1, described above there remains a free passage 15 between the axis 2 and the active part 1a-1b of the shutter 1.
  • free space 15 is an originality of the invention; it brings the advantage of being able to continue to load the hopper even during the stage of FIG. 2, which - in the devices of the known technique - corresponds to the stopping of the loading.
  • the 2nd time of the operating cycle is the transition from the situation according to FIG. 2 to that of FIG. 3.
  • the rod 7 ′ of the jack 7 being fully extended, it is left in this state, to maintain the articulation 2 in place of FIG. 2.
  • the actuator 4 is made to act, the rod 4 'of which then pushes upward the articulation 5, which drives upward the upper edge of the panel 6. This produces a traction of the panel 6 on the articulation 3 connecting it to the flap 1.
  • the triangle 1-4-6 is in the process of deformation and produces the work of loading the materials from the hopper 9 into the receptacle 13: the flap 1 pivots around the articulation 2 in the clockwise following the path indicated by an arrow drawn near the bottom of the hopper 9 ( Figure 2), pushing the materials towards the receptacle 13; at the same time, the panel 6 advances towards the entry of this receptacle, and exerts a precompression on the materials.
  • the steps 10, 10 ′ of the panel 6 improve the resistance of the latter and the retention of the materials.
  • the 3rd cycle time begins from the moment when the elements of the device have reached the position of FIG. 3.
  • the rod 7 ′ of the jack 7 is then retracted, the jack 4 remaining expanded: the two elements, 1 and 6, are then moved upwards, towards the entry of the receptacle 13, as shown by the arrow in FIG. 3. It is the compression phase which takes place, during that the assembly tends towards the position of figure 4.
