Description

(1) The disclosure below and the related figures, as a non-limitative example, will bring in better understanding of the innovation.

(2) FIG. 1.1 shows a perspective view.

(3) FIG. 1.2 shows a side view.

(4) FIG. 1.3 shows a front view.

(5) FIG. 1.4 shows a rear view.

(6) FIG. 1.5 shows an upper view.

(7) FIG. 1.6 shows the parts of the vibrating set.

(8) FIG. 1.7 shows the parts of the scale.

(9) To better understand the figures, we have given numbers to the parts:

(10) 1 Silo.

(11) 2 Vibrating set: (A) engine; (B) vibrating weight; (C) engine plate; (D) extender; (E) silo plate; (F) fixing rubber; and (G) vibrating plate.

(12) 3 Oscillating tray.

(13) 4 Funnel.

(14) 5 Scale (I) core plate (II) front plate (III) back plate (IV) crosswise plates (V) front cradle (VI) back cradle (VII) moving adjustable weight (VIII).

(15) 6 Pedal for the oscillating tray.

(16) 7 Pedal for the vibrating set.

(17) 8 Turn-off button for the doser.

(18) 9 Engine for the oscillating tray.

(19) 10 Oscillating axis.

(20) 11 Sustaining structure.

(21) 12 Doser composed by the items oscillating tray (3), funnel (4), scale (5), pedal for the oscillating tray (6), pedal for the vibrating set (7), turn-off button (8), engine for oscillating tray (9), oscillating axis (10), emergency (13).

(22) 13 Emergency button.

(23) FIG. 1.7 shows the scale composed by a central plate (I) fixed to the machine, leaving the moving cross plates (IV) by means of the pins with a nylon bush (VIII). The volume or weight to be packed into bags is put on the back cradle (VI) fixed to the back plate (III), providing the same amount to be on the front cradle (V) fixed to the front plate (II). For better regulation, a moving regulation weight (VII) is added.

(24) As shown by FIG. 1.1 from the perspective view, the product to be packed in bags is loaded to the silo (1) by the side part of the machine with a carrying shovel with wheels (backhoe). Pushing the activating pedal for the oscillating tray (6) turns on the engine for the oscillating tray (9), starting the filling operation.

(25) FIGS. 1.1 in perspective, 1.2 side view, 1.3 front view, 1.4 rear view and 1.5 upper view show the vibrating set (2) as detailed by FIG. 1.6 which, when activated by the pedal for the vibrating set (7) guides the material to the oscillating tray (3) sending it to a funnel (4) under which the pack to be filled in is located. When that package has the same volume or weight on the back cradle (VI) of the scale (5), it descends the front cradle (V) and activates the turn-off button for the doser (7).

(26) The silo (1) is manufactured with carbon steel plates about 3 mm thick with slope of more than 54 and, on one side on its lower part, at least 2250 mm wide to enable a spoon of the carrying shovel with wheels to deposit the material. On the lower part, there is a mouth not smaller than 200200 for the flow of the product to be packed at a maximum height of 2500 mm when already assembled over the machine.

(27) FIG. 1.6 shows the vibrating set (2) to pack the material in bags, avoiding the material to stick to the walls forming caves from the silo (1) to the oscillating tray (3), constituted by an engine (A) which, in its axis, has an eccentric weight (B) to perform the vibration, which is transferred to the 4 mm carbon steel plate (C) of the engine, transferring it to the prolongers (D) shaking the 4 mm vibrating carbon steel plate (G) which is screwed to the silo (1) plate; to provide for better durability and less noise between them, in a fixing rubber (F) with at least three canvas is included between them and activated by the pedal of the vibrating set (7).

(28) The vibrating set (2) is screwed to the lower part of the silo (1) and, over the upper part of the supporting structure (11), a square 80803 mm tube is supported, wherein, at the lower portion, the doser (12) is fixed and constituted by the items oscillating tray (3), funnel (4), scale (5), pedal for the oscillating tray (6), pedal for the vibrating set (7), turn-off button (8), engine for the oscillating tray (9), oscillating axis (10) and emergency (13), as detailed on FIGS. 1.2 side view, 1.3 front view and 1.4 rear view.

(29) The sloped 3 mm oscillating tray (3) of carbon steel is attached to the oscillating axis (10) exiting from the engine for the oscillating tray (9) which, when activated by the oscillating tray pedal (6), starts a back-and-forth movement, guiding the material to be packed into bags to the funnel (4) where the package is located, and is deactivated by the turn-off button (8) installed on the scale (5).

(30) For better safety, a red Emergency button (13) is provided to turn off the whole system.
