Abstract
Description
- The present invention lies in the technical field concerning batching granular and similar articles, in particular delicate and easily perishable articles.
- There are used 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.
- There is provided 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.
- Therefore, during the rotation of the carousel, the product in the channel of the carousel is pushed by the scraper into the spaces defined by the aforementioned casks.
- In fact, the fixed scraper leaves the product in the feeding channel while scraping it at the level of the batching casks.
- Such batching method cannot be applied when the bottles are to be filled with delicate products, that cannot be crushed.
- In fact, 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 above mentioned object is obtained in accordance with what has been reported in claims.
- The characteristics of the invention are pointed out in the following, with particular reference to the enclosed drawing, in which;
- fig. 1 shows a schematic, plan view of the batching device being the subject of the invention;
- fig. 2 shows a view, in vertical section, of such device, in the phase of feeding the product, according to the section line II-II of fig. 1;
- figs. 3, 4 and 5 show subsequent operative phases of the device, in a vertical section view, according to the section lines III-III, IV-IV, and V-V of fig. 1, respectively.
- With reference to the above mentioned figures, the
reference numeral 1 indicates the whole device for batchinggranular articles 2 destined to fillrelative bottles 3. - The
empty bottles 3 are fed along aline 4, in the direction indicated with the arrow A, and they are moved away, after having been filled, along aline 5 aligned with thesame feeding line 4. - The
device 1 includes acarousel 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 ofbatching casks 8, having vertical axis, are situated regularly spaced apart from one another. - Each
batching cask 8 is fixed with itsupper lip 8a to a respectiveelastic diaphragm 9. - The
diaphragm 9 has the outer border fixed to the edge of a relativecircular opening 10 made in the bottom of thechannel 7, and is open centrally in correspondence to the zone fixed to therelative batching cask 8. - Below the
diaphragm 9, eachbatching cask 8 is supported, by means of asupport bracket 11, by avertical rod 12 that, as specified in the following, is designed to be moved vertically in accordance with alternate directions. - The
rod 12 supports also arespective hopper 13 coaxial with thecorrespondent batching cask 8. - Therefore, the
hopper 13 is movable together with thecorrespondent batching cask 8. - The
hopper 13 is designed to enter into arelative bottle 3 to be filled, that is joined to thecarousel 6 in correspondence with each of thebatching cask 8. - The
bottle 3 is supported on thecarousel 6 by respective movingmeans 14, adapted to move vertically in accordance with alternate directions. - The lower part of
batching casks 8 is closed by ashutter 15, swingable on apin 16 fastened to thehopper 13. - The
shutter 15 is normally kept closed by acounter-weight 17, and can be opened at anunloading station 200 by special cam means 18. - The
bottles 3 fed by theline 4 are conveyed in an ordered manner to thecarousel 6 by a distributingmeans 19, such as rotating stars, in a suitable phase relation with thesame carousel 6. - A
similar distributor 20 transports filledbottles 3 from thecarousel 6 to theline 5 leading away. - The
carousel 6 is fed with thegranular articles 2 by afeeding hopper 21, placed over thechannel 7, in correspondence with astation 100 for filling thebatching casks 8. - A scraper means 22 is placed downstream of
such feeding hopper 21, according to the direction B of thecarousel 6 rotation. - According to the method for batching
granular products 2, carried out by the describeddevice 1, at the passage of abatching cask 8 in thefilling station 100, product is fed by thehopper 21 in a quantity slightly bigger than the pre-established dose, defined by the size of thesame batching casks 8. - Therefore, the
granular articles 2 fill thebatching cask 8 below, that, in this operative phase, is carried by therod 12 situated in a lowered position, so that theelastic 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). - In its lower part, the
batching cask 8 is closed by theshutter 15, thus the product is kept inside thesame cask 8. - It is to be noted that, since the quantity of the product is bigger than the single dose, the
batching cask 8 is certainly completely filled, and the part of the product in excess is collected at the bottom of the mouth formed by theelastic diaphragm 9, over thesame cask 8. - In a subsequent station of the
carousel 6, thebatching cask 8, previously filled, is shifted to the raised position, so that theelastic 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. - In this way, the
batching cask 8 is filled with a pre-established quantity of product, dose determined by the size of thesame cask 8. - Obviously, it is possible to change the dose of product, according to the need, by changing the size of the
cask 8. - Otherwise, it is possible to use batching casks made of two joined parts of telescopic form, so as to allow to vary the relative capacity.
- Therefore, the filling of the
cask 8 with the preestablished quantity of product occurs without any mechanical action on the articles, in particular, without crushing or similar actions that could jeopardise their integrity. - The limited quantity of product remaining over the
cask 8 after the raising movement, can be removed by the scraper means 22, in a subsequent station of thecarousel 6. (fig. 4) - It is to be noted that, such 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 theelastic diaphragm 9. - In the
subsequent discharge station 200 then, thecam 18 controls the opening of theshutter 15 of thebatching cask 8, so as to allow filling of therelative bottle 3 with the batched product (fig. 5). -
Such bottle 3 has been previously displaced to a raised position by therespective moving means 14, so as to come onto the exit of thehopper 13 that convey thearticles 2 discharged by thebatching cask 8. - The
bottle 3 already filled is carried again to the lowered position and directed orderly, by thedistributor 20, to theline 5 leading away. - In conclusion, the described method and device allow to fill the
bottles 3 with a batched quantity ofarticles 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.
- It is also to be pointed out that the method in subject is carried out by a device a very simple in its construction, so it is very convenient also economically, either from the point of view of production costs or use cost.
- In particular, the articles are batched in a spontaneous way by a single vertical upwards movement, that is imposed on the batching cask.
- It is understood that what about has been described as a mere, non limitative example, therefore, possible constructive variations are covered by the protection of the present technical solution, as described above and claimed in the following.
