[0007] With reference to Figures 1-2, the multi-functional packaging line subject of the present invention, extends longitudinally and it is able to pack products in two-piece box like packages, obtained by means of two separate blanks, that is, a blank-tray B, see Fig. 7, and a blank-cover A or A1, see Fig. 8 or 9, or else it is able to package the products in packages of the so called wraparound type, obtained by a single blank-wraparound C, see fig. 10.
[0008] The aforementined packaging line, with respect to a median horizontal plane that is substantially defined by the line II-II in Fig. 1, at the bottom side, compries lower dual-functional positioning-conveying-forming means, indicated in the assembly by 100, comprising individual means and/or functional groups, 110, 120, 130, 140, 150, best described below; said lower dual-functional positioning-conveying-forming means, 100, can alternatively be used to insert and position a blank-tray, B, Fig. 7, under the base of the products, and then to fold said blank-tray B around the product's base translating said blank-tray B downstream together with the product P, or else used to place a blank-wraparound C, Fig. 10, under the base of the products P, and then to fold the bottom portion of said blank-wraparound C around the base of products P, translating said blank-wraparound C downstream together with the product P.
[0009] This multi-functional packaging line also comprises, on the upper side, upper positioning-conveying-forming means, 200, which can be inserted or removed with respect to the multi-functional packaging line, where these upper positioning-conveying-forming means 200 are used to insert and position a blank-cover, A or A1, (Fig. 8 or 9) above the top of the product P, and then to push, translate and fold this blank-cover, A or A1, on top of the product P while the product P beneath is translated downstream.
[0010] Downstream these upper positioning-conveying-forming means, 200, there are upper forming-folding means, 300, preferably inserted and removed with respect to the packaging line, in which said upper forming-folding means 300 are mainly used to form and fold the upper portion of the blank-wraparound C (Fig. 10) on top of the product P, while said blank-wraparound C and the product P beneath are translated downstream, or else they can optionally be used to positively consolidate and/or grasp the top of the cover in order to optimise the operations of closing of a two-piece packaging.
Lower dual-functional positioning-conveying-forming means 100
[0011] With reference to said lower dual-functional positioning-conveying-forming means 100, in their upstream zone they comprise: lower inserting-positioning means 110, first pushing-conveying means 120 and second pushing-conveying means 130.
[0012] The lower inserting-positioning means 110 are able to insert and position, in an insertion zone Z1 of said packaging line, a blank-tray B or a blank-wraparound C.
[0013] More particularly, said lower inserting-positioning means 110, see also Fig. 3-5 and 5-6, are able to insert a blank-tray B, or a blank-wraparound C, under the product P, by inserting and positioning the blank, B or C, under a sliding dead plate, 125, on whose upper surface the product P can slide, in which said product P is illustrated hereby as a lot of bottles without any limitations with respect to the other type of products, either monolithic or of other type.
[0014] In particular, see Fig. 3, the blank-tray B is inserted in a flat configuration under the dead plate 125, while, as seen in Fig. 5, the blank-wraparound C is inserted in a folded configuration, with lower panels C-Pl and back panels C-PP horizontally coplanar to each other placed under the dead plate 125, with the front panel C-PA vertically placed in front of the front side of the product P, and with the panels C-PS and C-LC vertically placed.
[0015] In order to perform the aforementioned insertion-positioning operations, in the illustrated example, said inserting-positioning means 110 comprise a first conveyor belt, 111, which extends transversally with respect to the packaging line, preferably of the suction type or equipped with grasping means, in which the upper branch of said inserting-positioning means 110 is able to grasp the lower face of the blank-tray B or of the blank-wraparound C, and then convey and position them within said packaging line in the first zone Z1, with the eventual help of positioning-abutting means of end of stroke and/or guide means.
[0016] For this purpose, preferably, said conveyor belt 111 has a first end portion, 111 a, externally placed with respect to the packaging line, and a second end portion, 111b, internally placed with respect to the packaging line, in order to feed the blanks in a single succession and in a synchronised manner with respect to the machine cycles.
[0017] The first pushing-conveying means 120, preferably, comprise a suspended bars pushing system 121, in which said bars 121 are supported by chains 122sx and 122dx and are used to push-convey the product P downstream by sliding it over the dead plate 125.
[0018] The second pushing-conveying means, 130, are used to push and convey the blank-tray B, or the blank-wraparound C, from the said first zone Z1 downstream along the packaging line and, in the given example, they comprise a chain 131 equipped with pushing teeth 132, in which said chain 131 travels in a closed loop with an operative upper branch extending from upstream to downstream and running into a slot 112 obtained in the end portion 110b of the conveyor belt 111 (see also fig. 1 C).
[0019] Downstream from the dead plate 125 there are lower longitudinal flat-transportation means 140 which include two transport belts, 141 sx and 141 dx, preferably of suction type, transversally spaced, traveling in a closed loop, used for moving downstream the blank-tray B or the blank-wraparound C on which the product P is placed.
[0020] In addition, it is preferably that between said belts, 141sx and 141dx, the upper branch of the chain 131 with the pushing teeth 132 of the pushing-conveying means 130 is to be moved longitudinally.
[0021] Finally, downstream from the flat-transportation means 140 there are lower conveying-folding means 150, of the two groups with multiple chains type, 151 sx and 151dx, in which said chains are used to carry abutting-folding elements 152sx-152dx and pushing-folding elements 153sx-153dx.
[0022] Furthermore, close to the lower conveying-folding means 150, there can also be rotating folding means, 154sx and 154dx, one or more stationary folding means, 155sx-155dx and 156sx-156dx, and lower gluers 160sx and 160dx.
[0023] It is preferable for the second pushing-conveying means 130 to extend longitudinally from the upstream zone of the inserting-positioning means 110 to the upstream zone of said lower conveying-folding means 150.
Upper positioning-conveying-forming means 200
[0024] In the upper side of said packaging line there are upper positioning-conveying-forming means 200, which are supported from the top hanging towards the bottom by means of vertical translator means 250 used to move and position them vertically, in order to get a change in size with regards to the product's height, and, in addition, used to obtain two configurations: a)-a first operative lowered configuration, in which said positioning-conveying-forming means 200 are inserted within the packaging line and can position, convey and form covers on top of the products, and b)-a non-operative lifted configuration.
[0025] Said upper positioning-conveying-forming means 200, for example, can comprise: >-upper inserting-positioning means 210; >-upper pushing-conveying means 220, >-upper pushing-conveying-folding means 230.
[0026] The upper inserting-positioning means 210, preferably driven by a servo-motor M210, are used to insert and position, in a suspended manner, in an insertion zone Z1 of the said packaging line, in a single succession and in synchronization with the packaging cycles, a blank-cover A or A1, in a folded configuration, in front of and above the product P, with the back panel A-PP and the upper panel A-PS horizontally coplanar placed above the upper side of the product P and with the front panel, A-PA, vertically placed in front of the front side of the product P.
[0027] In the illustrated example, the inserting-positioning means 210 include a conveyor belt 211, preferably of suction type, transversally extended with respect to this packaging line, whose lower branch grasps the upper face of the upper panel A-PS and/or the back panel A-PP of the blank-cover A, and then convey it in a folded configuration into the said products packaging line and place it in the first zone Z1.
[0028] This suction conveyor belt 211, preferably, has a transversal section placed into the assembly line inclined from top to bottom and downstream with respect to the product's movement, and, also, said suction conveyor belt 211 has a predetermined suction force able to maintain the blank-cover A suspended in said zone Z1, and able to allow the downstream translation of said blank-cover A held suspended by suction when an external force is applied.
[0029] In order to insert blank-covers A in a continuous succession rate, said conveyor belt 211 has a first end portion, 211 a, externally placed with respect to the packaging line, and a second end portion 211 b, internally placed with respect to the packaging line.
[0030] The upper pushing-conveying means 220, preferably driven by the servo-motor M220, are used to push and convey the blank-cover A, in this folded configuration, from the first zone Z1 downstream along the products packaging line, as soon as the front side of the product P come against and/or near the front panel A-PA of the blank A.
[0031] In the illustrated embodiment, said pushing-conveying means 220 include a closed-loop travelling chain 221 equipped with pushing teeth 222, in which said chain 221 travels into a groove 212 that extends longitudinally obtained through transmission shaped like an inverted "U" of the suction conveyor belt 211.
[0032] The upper pushing-conveying-folding means 230, preferably driven by a servo-motor a servomotor M230, are mainly used to abut the upper front edge of the front panel A-PA of the blank-cover A / A1, to convey this blank-cover A / A1 downstream along the products packaging line, and to fold the back panel A-PP of the blank-cover A against the back side of the product P.
[0033] In the illustrated realisation, said upper pushing-conveying-folding means 230 include a conveyor group with multiple chains, 231 sx and 231 dx, equipped with abutting-folding elements 232sx and 232dx, and folding-pushing elements 233sx and 233dx.
[0034] In addition, if required, close to the pushing-conveying-folding means 230 there can also be rotating folding means 244sx and 244dx and/or stationary folding elements 245sx, 245dx, 246sx, 246dx, and/or gluers 260sx and 260dx.
Upper forming-folding means 300
[0035] In the upper side of said packaging line there are upper forming-folding means 300, which are supported from the top hanging towards the bottom by means of vertical translation means 350 used to vertically translate and position the aforementioned upper forming-folding means 300, in order to obtain a change in size with respect to the product's height, and, in addition, if desired, able to obtain two configurations: a)-a first operative lowered configuration, in which said third forming-folding means 300 are inserted within the packaging line for a positive forming of the upper portion of the two-piece packaging, or for a positive forming of the upper portion of the blank-wraparound on top of products P, and b)-a second non-operative lifted configuration.
[0036] In the illustrated example, said upper forming-folding means 300 include a conveyor group 310, preferably driven by a servomotor M310, comprising multiple chains, 311 sx and 311 dx equipped with abutting-folding elements 312sx and 312dx and with folding-pushing elements 313sx and 313dx.
[0037] Furthermore, close to said upper forming-folding means, 300, there can also be rotating folding means, 320sx and 320dx, stationary folding means, 330sx and 330dx, and upper lateral gluers 361 sx and 361 dx, as well as other gluers 370 (Fig. 6).
