Description
- This invention relates to the technical field concerning the machines designed for packaging containers which, during their handling, (closing of the bottom, filling with products, closing of the upper head) are vertically oriented, with reference to their longer dimension.
- In detail, said machines basically comprise:
- a magazine of blanks of flattened tubular form;
- a device to intermittently take the lower blank of the pile of blanks contained by said magazine, and to transfer the same blank with progressive definition of the relative open tubular form, into a corresponding seating of a conveying line;
- said conveying line, made up of a conveyor provided with means defining a plurality of said seatings, with fixed spatial attitude, which in a feeding station located close to the initial part of the inner branch of the conveyor are designed to receive, and to check elastically, corresponding blanks of said open tubular form;
- first means, associated with said inner branch, to close, in cooperation with glue-applying means, the bottom of the blank, so as to form a corresponding container open at the top;
- a feeding station located between the terminal part of the inner branch of the conveyor and the initial part of the outer branch of the latter, designed to insert into said container, from above downwards, a predetermined quantity of products, particularly loose products, such as: pasta, rice, etc., or products in powdery and/or granular form, such as sugar, detersives, etc.;
- second means, associated with the outer branch of the conveyor, designed, in cooperation with glue-applying means, to close the upper head of said container already filled with products;
- means for transferring the packaged containers from said outer branch to a reception line.
- In the machines known hitherto, the seatings to receive the blanks of open tubular form are, as mentioned above, with fixed spatial attitude, consisting of drawers or being defined by as many pairs of consecutive blocks, and the magazine is oriented perpendicularly with respect to the longer dimension of the conveyor, with all the problems of encumbrance involved.
- By means of a device of known type, the lower blank of the pile of blanks contained by the magazine is caught and transferred to said feeding station; during said transfer the blank is unfolded, i.e. it is brought from the flattened tubular form to the open tubular form.
- The magazines used, associable with said device, do not allow the automated loading of blanks, since said pile is subject to the action of elastic means which keep it pressed against the check means in contrast with which the device intermittently catches the blanks.
- In fact, in order to carry out the loading, it is necessary to disengage said elastic means from the pile, and that is precisely why the automatic loading of the magazine is not possible.
- On today's date the Applicant filed a Patent Application no. 3388A/90, concerning a machine in which, besides other things, said reception seatings are defined by at least two prongs, borne by relative chains, respectively for catching (the front one) and for pushing (the rear one).
- In order to allow the insertion of blanks of open tubular form into relative seatings thus defined, the Applicant invented a device designed to intermittently catch the blanks of flattened tubular form from the bottom of a pile of containers contained by a magazine, and to subsequently transfer the blanks into said seatings, with "unfolding", at least partial, of the same blanks during said transfer.
- One of the objects of this invention is precisely the provision of a device performing the functions mentioned above, and designed to exploit also the movement of the prongs defining said reception seatings to complete the "unfolding" of the tubular blank, with consequent advantageous effects in terms of productivity of the device itself.
- A further object of this invention is the provision of a device which, besides the features mentioned above, is suited to act on the lower blank of a pile of blanks located in a magazine, disposed parallel to the longer dimension of the conveyor provided with said pairs of corresponding prongs, with said magazine devised in such a way as to allow the automatic loading of blanks.
- The objects mentioned above are accomplished by means of a device to take blanks, of flattened tubular form, from a magazine, and to open them blanks during their transfer to a packaging line, as defined in
claim 1. - This device involves positive effects, on one hand, in terms of productivity and on the other hand of reliability of the latter, since the opening of the blank is always assured.
- The technical solution provided by the present invention allows to take the lower blank of a pile of blanks contained by a magazine disposed parallel to the direction of maximum extension of a conveyor (with substantial reduction of the dimensions of the conveyor-magazine unit and device provided by the invention), with said taking carried out according to a direction perpendicular to the lower blank.
- Subsequently said blank is transferred, partially unfolded, into a seating where prongs complete the unfolding process.
- The particular conformation of the device provided by the invention allows the employment of a magazine suited to allow the automated loading of blanks.
- The present invention will be described further, by way of example, with reference to the accompanying drawings, wherein:
- Fig. 1 is a side diagrammatic view of the device conforming to the invention;
- Fig. 2 is a view of said device according to the direction X of fig. 1;
- Fig. 3 is a view of said device according to the direction Y of fig.1;
- Fig. 4 is a view of a section, obtained through an axial plane, of the means designed to take, from an intermediate station, a tubular blank of flattened form, and to transfer said blank, with the gradual opening of the same, between the prongs, (which carry out the opening), of a container-packaging line.
- Referring to said figures, the
numeral 1 generally designates a tubular flattened blank, a die-cut blank for instance, of the type defined by fourconsecutive side walls remaining walls relative flaps - The
blanks 1 are stacked in a magazine 6 made up of ahorizontal portion 6a and aportion 6b, consecutive to the former, inclined downwards. - In the
portion 6a theblanks 1 result to be inclined with respect to the horizontal axis, while in theinclined portion 6b the same blanks are normal to the axis of the latter portion. - The lower blank 1a of the pile P of blanks 1 (with said pile contained by the
inclined portion 6b) is supported by known elastic check means, not illustrated; the extension of saidportion 6b is such as to avoid overloading said elastic means. - Conventional means, not illustrated, cooperating with suitable sensors, also not illustrated, provide for translating, according to F, the blanks present in the
horizontal portion 6a of the magazine 6, so to maintain theinclined portion 6b of the magazine always full of blanks. - Said horizontal portion may also be loaded automatically, e.g. by means of automated units; this is made possible by the fact that on said
horizontal portion 6a no means to press the pile are required, thus allowing the automated loading, with all the advantages involved. - The lower blank 1a of the pile P defines a station S from which the blanks are taken.
- First means 7 provide for taking the lower blank 1a, and subsequently for transferring it to an intermediate station I where the same blank results to be in horizontal position (fig. 1).
- Said means 7 are made up of a
sleeve 8, hinged in 9 to the supportingstructure 50 of the device, with which results to be telescopically coupled astem 10, whose free end bears sucker means 11 fed in a known way, not illustrated; for the sake of simplicity only a single sucker is illustrated, but it is understood that the number of suckers depends on the surface of the blank 1. - With the
stem 10 is articulated, in 12, the end of anarm 13 whose other end is hinged, in 14, to said structure. - Through
means 70 thearm 13 is made rocking, according to A1-A2, between two limit positions and vice versa, individuating corresponding positions Z1, Z2, for thesucker 11. - The
sucker 11 in the position Z1 mates at least a side wall of the blank 1a, e.g. saidthird wall 4, while in the position Z2 it is horizontal, as well as turned upwards. - The rotation of the
arm 13 according to A1 initially causes a translation of thestem 10 parallel to the axis of theinclined portion 6b of the magazine (which is extremely advantageous, since it optimizes the disengagement of the lower blank 1a from the elastic means checking the pile P) and, subsequently, a gradual rotation of the same stem with respect to thefulcrum 9, according to A1, combined first with the re-entering and subsequently with the coming out of this latter into and from thesleeve 8. At the end of the oscillation of thearm 13, in the sense A1, thesucker 11 is in the position Z2 and the blank is positioned, horizontally, in the internediate station I. - In this latter station, sucker means, e.g. consisting of a
sucker 15, associated withsecond means 16, provide for catching the blank 1, e.g. in correspondence with thefirst side wall 2, in a suitable relationship of phase with the deactivation of thesucker 11. - The
means 16 take the blank 1 from the intermediate station I to transfer it subsequently into avertical seating 45 formed by a pair ofprongs packaging line 18, whoseinner branch 19a andouter branch 19b result to be parallel to the axis of thehorizontal portion 6a of the magazine 6. - The
line 18 is made up of at least twochains - The
first chain 80 bears, equally spaced, the pushingprongs 17b, radially oriented outwards, and thesecond chain 81 bears, equally spaced, thecatching prongs 17a, in the same number as the former prongs, also radially oriented outwards. - Thus a series of
vertical seatings 45 is individuated, each of which is defined by at least onecatching prong 17a and by at least a corresponding pushingprong 17b; said seatings pass through a feeding station R defined by the initial part of theinner branch 19a of theconveyor 18. - In detail, as will be pointed out below, said means 16 impart the blank a composite motion, at the end of which the axis of the blank moves from the horizontal position to the vertical one (fig. 1), while the walls of the same blank result to be rotated by 180 degrees (clockwise with reference to the view of fig. 1) with respect to the above-mentioned axis.
- During said motion, the blank intercepts a fixed catch projection 60 (fig. 3) which provides for unfolding the blank partially; the unfolding is completed, with the consequent definition of the open tubular form of the blank, by the combined action of the
prongs - The
means 16 are made up of acylindrical shell 20, fastened to thestructure 50, whoseaxis 40 results to be inclined by 45 degrees with respect to two perpendicular planes, respectively horizontal and vertical. - Said shell revolvingly supports, inside itself, through known
means 22, atubular turret 21 whose upper portion is provided with twotubular projections axis 40. - Said projections revolvingly support, inside themselves, through known
means 27,relative shafts respective bevel gears 28a, 28b in mutual meshing with onebevel gear 29 splined to the end of ashaft 30 located inside theturret 21 and revolvingly supported by this latter through knownmeans 32. - At the ends of the
shafts corresponding projections corresponding arms - In the accompanying drawings, the raceways, as well as the means designed to feed the
suckers - The
tubular turret 21 is drawn into rotation, according to M throughmeans 23, while theshaft 30 is drawn into rotation throughmeans 31; said means are motorized in relationship of phase with the motorization of thechains arm 13. - The unit made up of the
means 31 and thebevel gears shaft 25a in the sense N according to an angular speed double with respect to the angular speed of theturret 21; in other words, to every revolution of the turret correspond two revolutions of theshaft 25a. The same principles also apply to theshaft 25b. - Referring to figs. 1, 2 and 3, the
means 16 are illustrated, by a continuous line, in the position wherein thesucker 15 mates thefirst side wall 2 of the blank, while thesucker 15a has just completed the transfer of a blank, partially open, between a pair ofcorresponding prongs - In the above-mentioned position, the
sucker 15a is deactivated, while thesucker 15 is activated. - Reference is made, here below, to the operating unit comprising the
sucker 15. - The 180-degree rotation of the
turret 21 according to M brings about a gradual rotation of the longitudinal axis of the blank 1 which moves from horizontal to vertical; said rotation, with reference to figs. 1 and 3, is counterclockwise. - If the
shaft 25a were fixed, said rotation would involve a synchronous rotation of the side walls of the blank with respect to said axis; during said rotation a portion of the blank (not affected by the sucker 15) would intercept a fixed catch projection, with the consequent partial unfolding of the blank. - With the solution mentioned above, the blank, partially unfolded, would be inserted into the
seating 45, defined by theprongs inner branch 19a of theline 18; this, when the action of the fixed catch projection ceases, could bring about either the re-closing of the blank, or its coming out of theseating 45. - This drawback is avoided by the rotation, according to N, of the
shaft 25a. - Said rotation, contrary to the rotation of the relative
tubular projection 24a, is by 360 degrees (as compared to 180 degrees of the turret), thus the blank corresponding to theseating 45 results, with respect to the relative longitudinal axis, to be rotated by 180 degrees in a sense contrary to the sense M according to which theprojection 24a is rotated. - The above-mentioned principle makes it possible to insert the blank, partially unfolded by the catch projection 60 (which intercepts, e.g., the second wall 3), in the
seating 45 with a speed component H contrary to said sense T. - Thus the edge common to the
walls prong 17b, while the edge common to thewalls prong 17a. - The above-mentioned situation prevents the partially unfolded blank from coming out of the
seating 45; the gradual decrease, up to the predetermined value, of the distance between theprongs - At this point the
sucker 15 carries out its idle run to return to the intermediate station I, and at the same time theother sucker 15a takes from this latter a blank of flattened form: thesucker 15a performs the same operating steps described above with reference to thesucker 15. - The conformation of the
means 16 is such as to exploit theprongs
