Definitions

  • the present invention lies in the technical field concerning batching granular and similar articles, in particular delicate and easily perishable articles.
  • batching devices that fill bottles or other containers with a prefixed quantity of a product, e.g. granular, powdered or similar substances.
  • Such devices usually have a rotating carousel equipped peripherally with a plurality of batching casks, distributed regularly, in contact with a space or an angular channel that is fed with the product to be put in the bottles.
  • the lower parts of the casks are closed by a shutter that can be opened, in a special operative station, in order to unload the product into a hopper aimed at filling a bottle that is placed below.
  • the aforementioned casks are designed to define the dose of the product to be put in each bottle.
  • the casks are filled with the product put into the feeding channel of the carousel.
  • a fixed scraper means that extends vertically in a shutter like fashion inside the carousel channel, that is up to the bottom of the same channel, e.i. at the level of the upper border of the casks.
  • the fixed scraper leaves the product in the feeding channel while scraping it at the level of the batching casks.
  • the batching means compresses the product that is forced against it by the carousel rotation. Such mechanical action can crush a part of product and cause its damage.
  • the object of the present invention is to propose such a method for batching granular and similar products that surely avoids crushing or damage of the product.
  • the reference numeral 1 indicates the whole device for batching granular articles 2 destined to fill relative bottles 3.
  • the empty bottles 3 are fed along a line 4, in the direction indicated with the arrow A, and they are moved away, after having been filled, along a line 5 aligned with the same feeding line 4.
  • the device 1 includes a carousel 6 rotating step by step about a vertical axis, in the direction indicated with the arrow B.
  • the carousel 6 has a peripheral ring-shaped channel 7 in correspondence with which a plurality of batching casks 8, having vertical axis, are situated regularly spaced apart from one another.
  • Each batching cask 8 is fixed with its upper lip 8a to a respective elastic diaphragm 9.
  • the diaphragm 9 has the outer border fixed to the edge of a relative circular opening 10 made in the bottom of the channel 7, and is open centrally in correspondence to the zone fixed to the relative batching cask 8.
  • each batching cask 8 is supported, by means of a support bracket 11, by a vertical rod 12 that, as specified in the following, is designed to be moved vertically in accordance with alternate directions.
  • the rod 12 supports also a respective hopper 13 coaxial with the correspondent batching cask 8.
  • the hopper 13 is movable together with the correspondent batching cask 8.
  • the hopper 13 is designed to enter into a relative bottle 3 to be filled, that is joined to the carousel 6 in correspondence with each of the batching cask 8.
  • the bottle 3 is supported on the carousel 6 by respective moving means 14, adapted to move vertically in accordance with alternate directions.
  • the lower part of batching casks 8 is closed by a shutter 15, swingable on a pin 16 fastened to the hopper 13.
  • the shutter 15 is normally kept closed by a counterweight 17, and can be opened at an unloading station 200 by special cam means 18.
  • the bottles 3 fed by the line 4 are conveyed in an ordered manner to the carousel 6 by a distributing means 19, such as rotating stars, in a suitable phase relation with the same carousel 6.
  • a similar distributor 20 transports filled bottles 3 from the carousel 6 to the line 5 leading away.
  • the carousel 6 is fed with the granular articles 2 by a feeding hopper 21, placed over the channel 7, in correspondence with a station 100 for filling the batching casks 8.
  • a scraper means 22 is placed downstream of such feeding hopper 21, according to the direction B of the carousel 6 rotation.
  • product is fed by the hopper 21 in a quantity slightly bigger than the pre-established dose, defined by the size of the same batching casks 8.
  • the granular articles 2 fill the batching cask 8 below, that, in this operative phase, is carried by the rod 12 situated in a lowered position, so that the elastic diaphragm 9 is kept taut so as to protrude downwards thus forming, in its upper part, a concave surface that acts as mouth for the same batching cask 8 (fig. 2).
  • the batching cask 8 is closed by the shutter 15, thus the product is kept inside the same cask 8.
  • the batching cask 8 previously filled, is shifted to the raised position, so that the elastic diaphragm 9 is kept taut to protrude upwards thus forming, in its upper part, an inclined convex surface, that is a truncated cone (fig. 3).
  • Such displacement causes, in a spontaneous way, the removal of the product in excess that, due to gravity, comes down along the inclined surface formed by the elastic diaphragm 9 and is collected in a peripheral zone.
  • the batching cask 8 is filled with a pre-established quantity of product, dose determined by the size of the same cask 8.
  • the filling of the cask 8 with the pre-established quantity of product occurs without any mechanical action on the articles, in particular, without crushing or similar actions that could jeopardise their integrity.
  • scraper means 22 skims the upper edge of the batching cask 8, removing the exceeding articles without crushing them, since the articles are pushed to fall freely on the inclined surface of the elastic diaphragm 9.
  • the cam 18 controls the opening of the shutter 15 of the batching cask 8, so as to allow filling of the relative bottle 3 with the batched product (fig. 5).
  • Such bottle 3 has been previously displaced to a raised position by the respective moving means 14, so as to come onto the exit of the hopper 13 that convey the articles 2 discharged by the batching cask 8.
  • the bottle 3 already filled is carried again to the lowered position and directed orderly, by the distributor 20, to the line 5 leading away.
  • the described method and device allow to fill the bottles 3 with a batched quantity of articles 2, without exerting any mechanical action i.e. compressing or crushing thereon.
  • the subject method and device are therefore particularly efficient in case of batching products delicate or easily perishable in consequence of mechanical actions as those cited above, in particular granular and similar articles.
  • the articles are batched in a spontaneous way by a single vertical upwards movement, that is imposed on the batching cask.
