Definitions

• the present invention refers to a machine for packaging in containers, for example boxes or cases, objects of any nature such as bottles, bricks, cans, paper material, containing liquid or solid products, distributed in an orderly manner on one or more rows in the pick-up station.
• the invention refers to a machine that is particularly efficient and functioning.
• boxing machines suitable for collection containers to then position them inside further specific containers (for instance bottles and the like in containment boxes) have long been known.
• this type of machine is called also crating machine or boxing machine and must operate in conjunction with other machines (filling machines, corking machines, shrink wrappers, sorting machines) in a packing line.
• This type of machine can operate in contexts characterized both by low and by high production volumes .
• the packing and storage field encloses a great variety of articles to package with significant differences of materials, sizes and types of products to handle. This determines the need to have a great flexibility of adaptation to the different types of products in terms both of size and of characteristics of the materials used for the products themselves.
• US3209923 is for example known, which describes a boxing machine.
• the bottles that travel in an orderly manner on a conveyor belt arrive to a collection area where they are collected through a translating carriage along a rail and positioned above the bottles.
• the carriage, apart from translating, can lower/lift the pickup organs that are composed of a sort of cups that make the suction and therefore collect, each one, a single container.
• the pick-up organs that collect the bottles and lift them are lowered in such a way that the carriage can translate in a release area to then position them in an orderly manner in specific containers.
• the containers foresee single lodging seats of the bottles and such ' seats are delimited by separation walls that detach a seat from the other ones. It is clear that the thickness of such walls, inside a container, cannot be exactly the same as the distance between a container and another one positioned side by side.
• the solution is obtained with the pick-up organs that are formed by a number of supporting plates equivalent to the number of cases where to release the containers and each plate having a number of cups equal to the number of bottles to collect.
• the two front plates are then assembled on a translating system that allows to space them from the back ones .
• each plate foresees a pre-arrangement of cups that reflects the order of the seats foreseen in the containers where to position the bottles and, in addition, the fact that the front plates can be moved apart/drawn near to the back ones makes that the two front plates go in correspondence of two front cases and the back ones are spaced adequately to, go in correspondence of the back cases.
• the pick-up organ described is now mobile along an inverted U-shaped curve cogwheel rail.
• a support that supports the head foresees two opposed crown gears that engage along the path.
• Such support is then fixed slidingly, through two rings, to a vertical guide which, through a sliding block is contextually sliding along a horizontal guide.
• the head follows the curve path, keeping its longitudinal axis rigorously perpendicular to the horizontal support surface.
• the movimentation is obtained through a grip of the gear wheels on the toothed guide.
• This solution is complex and subject to wear. Further, the system needs frequent lubrication actions of the organs, rendering the system not idoneous to all working environments (for example the food one) . It is therefore necessary to intervene periodically with a . substitution of the guide and of the crown gears.
• the invention has the objective of allowing to carton great quantities of product at high speeds, with the help of absorbed low power with respect to the machines currently in commerce.
• Such machine comprises:
• a movimentation system (31, 33, 34) that moves the collection group (20, 50) along said guide (10).
• a first motorized system (22) is foreseen that, during the movimentation of the collection group along the guide, controls a further movimentation of at least one part of the collection group (20, 50) relative to the guide in such a way that during all the course of the guide from the collection area to the release area the containers transported can vary or keep a pre-determined inclination and wherein, further, the movimentation system of the collection group foresees at least one flexible belt-like element, for example in the form of a belt (30) or a chain, to which said collection group (20, 50) connects, a multiplicity of rotating elements (31), for instance in the form of pulleys or pinions, assembled rotatably with respect to the guide and that define a path of passage for said flexible belt-like element along the guide and a second motorized system (34) that conducts such flexible beltlike element to move along the guide in a direction or in the opposite direction, thus dragging integrally the collection group.
• the flexible belt-like element for
• the translation system along the guide in the form of such flexible belt-like element for example a belt-pulley or, alternatively, chain-pinion (or crown gear) coupling, allows to obtain a machine as a whole structurally simpler and that requires low maintenance.
• the substitution, in fact, of a worn belt or of a chain is something that is much faster and quicker than the substitution of crown gears. Further, few lubrication is needed that allows the use of such machine also in the food industry.
• the first motorized system which controls the rotation of at least one part of the collection group (20, 50) makes that the machine as a whole is structurally simpler apart from being more versatile.
• FIG. 1 is an axonometric view of the machine illustrating the preferred embodiment of the conveyor belts, of the lifting system of the head and of the alignment system of the heads;
• FIG. 2 is an exploded view of the guides and of the assembly 20 that moves on the guides and drags the pick-up heads;
• FIG. 4 is an axonometric view of the servomotor 22 assigned to adjust the inclination of the pick-up heads;
• Figure 7 and figure 7A both show in an axonometric view the group (20, 50) forming by the assembly 20 to which the assembly of support of the pick-up heads connects;
• FIG. 14 is an axonometric view of a complete line
• FIG. 15 is, last, an axonometric view that highlights the unload area provided with the packing cartons.
• Figure 1 shows in an overall axonometric view the boxing machine, which is composed of a frame 100, preferably of parallelepiped shape with quadrangular base, having two columns 101 opposed one to the other on which the cams 10 (or guides 10) on which the carriages slide are anchored, described more in detail below.
• figure 2 extrapolates from the assembly of figure 1 the two cams 10 to better highlight them and to which the motorized system 22 connects to adjust in an automatic manner the inclination of the pickup head.
• the two cams are spaced one from the other and between them a collection group (20, 50) is interposed which, through said motorized system 22, is capable of modifying and eventually keeping constant a pre-determined inclination of the pick-up heads.
• the two cams 10 are inverted U-shaped.
• each cam foresees two parallel rectilinear sections, joined between them through a semicircular section.
• the cams form a sliding guide for the pick-up group (20, 50) to which the pick-up heads are fixed.
• the assembly described in detail below, moves along such two guides, being able to adjust the inclination of the pick-up heads in an automatic manner (being such assembly motorized) .
• the collection group can be thought of as composed of an assembly 20 to which the underlying group 50 is connected that foresees the attachment means to connect, in a removable and interchangeable manner, the various pick-up heads.
• rotational elements are applied, around which a flexible belt-like element is made to pass which can be moved to drag the assembly 20.
• the cam creates a support for such rotational elements around which such flexible belt-like element that drags the group (20, 50) passes.
• figure 3 shows the arrangement of a belt 30 for each cam.
• the flexible belt-like element is therefore in the form of a belt.
• the belt is moved by a further motorized system 34 and is connected to it, as also highlighted in figure 3, the assembly 20.
• the movimentation of the belts drags in an integral manner the assembly 20 along the cams and therefore the underlying group 50 and the relative pick-up heads.
• each cam or guide
• Each pulley is interposed in the space between the cam 10 and a metal wall 32 making part of the frame.
• the belt 30 can, for example, be of the toothed type and make grip with the pulleys which are toothed as well.
• such flexible belt-like element could be in the form of a transmission metallic chain with relative pinions or crown gears in the place of the pulleys and that make grip on the chain.
• Figure 3A shows in an enlargened view a single belt applied to only one of the two cams and highlights the axis 33 that transmits the motion through a rotary engine 34 (see figure 3) .
• the axis 33 rotates and conducts in rotation a pulley 31' around which the belt passes.
• the pulley 31' is preferably toothed and in figure 3A it is not totally visible since it is covered by the passage of the belt.
• the belt follows the course of the cam, passing around the pulleys that, as said, are fixed rotatably between cam and wall. The belt is therefore operated through the rotation of the motorized pulley 31' .
• the pulley 31' rotates and conducts in rotation the entire belt whose motion is facilitated by the rotation of the other pulleys assembled idle and on which it is made to pass.
• the assembly 20 (shown in figure 3 and 3A in a simplified manner) connects to the two belts (or chain according to the solution) in such a way as to be dragged integrally by them along the path defined by the two guides .
• connection takes place through a plate 21 that is fixed to the two belts (or equivalently to the chains) .
• the assembly 20 is described in greater detail with reference to figures 3, 4 and to figure 5.
• the electric motor 22 is foreseen that conducts in rotation the toothed pulley 23 to which a toothed belt 24 connects that wraps the pulley 25 conducted by the rotation axis 26.
• the pulley 25 is in fact integral to the axis 26.
• the axis 26, through the ends thereof 26' is inserted in the carriages 27, represented also in figure 5, and that move each one along a cam (see also figure 2) .
• Figure 5 shows, for each carriage, four wheels in the shape of two opposed pairs and fixed each pair to the own support (27a, 27b) .
• the support (27a, 27b) as described is assembled in an articulated manner with respect to the plate 27' .
• the wheels have the possibility of adapting themselves to the course when it passes from the rectilinear configuration to the curve one, following faithfully the profile.
• the plate 27' is rigidly connected with the plate 21 (with a preferred angulation at ninety degrees) .
• the wheels are characterized by a V-shaped section that allows the carriage to be perfectly guided.
• Figure 6 in fact shows the section G-G of the cam that, externally, forms a V-shaped profile on which the single wheel makes ' grip .
• the wheels can also be in a different number to four, for example three (one opposite to two wheels) or only two, opposed.
• the engine leans on a support ( S ) that forms a support surface and, at its ends, two rings of passage of the axis 26.
• a support ( S ) that forms a support surface and, at its ends, two rings of passage of the axis 26.
• rotatory bearings 26' ' ' that allow, as clarified in the functioning, to make such support (S), and what is connected to it, rotate with respect to the axis 26.
• Figure 15 shows that the support (S) is connected rigidly to the underlying part 50 made by a further engine 52, a sliding binary 51 and coupling 53 for pick-up heads.
• An intermediate plate (PI) connects the plate (S) to the underlying group described.
• This system allows to adjust and keep at will a pre-determined inclination of the pickup heads since, during the course of the group along the cams, the engine causes a rotation, around the axis 26, of the plate (S) and of the underlying group connected to it (and therefore as a consequence also the pick-up heads) .
• the engine 22 is fixed to a support plate (S' ) , rendered integral to the plate (S) .
• the assembly 20 runs the entire cam 10, passing by the rectilinear section 10' to the curve section 10' ' to terminate in the rectilinear section 10''' .
• the pick-up heads are brought from the collection area to the unload area and vice-versa.
• the four wheels of the carriage 27 follow the profile of the cams thanks to the fact that they are assembled on the articulated supports (or the plates 27a, 27b of figure 5) .
• the automated adjustment system, 3.S j_t is structured, makes that the group formed by the support (S), engine 22 and the underlying group 50 to which the pick-up heads are fixed can rotate to compensate the curvature of the cam, keeping the pick-up heads always in a position orthogonal to the supporting plane from the pick-up area to the release area and vice-versa, or keeping other inclinations and/or varying them if necessary .
• the structure of the group (10, 50), together with the engine 22, allows instead an automated adjustment.
• the end 26' of the axis 26 is inserted with interference (or preferably is blocked with known blocking systems) in the hole 26' ' .
• the support (S) to which the engine connects 22, and therefore also the group 50 with the underlying pick-up heads, are instead rotatable, through the bearings 26''' with respect to the axis 26.
• the assembly of figure 4 functions inversely. It is not the axis 26 that rotates thanks to the operation of the engine 22 but it is the engine group, the support (S) and the underlying group that thanks to the operation of the engine itself brings itself in rotation around the axis 26.
• Figure 10 shows in a sequence of three phases of example the movimentation of the entire group (20, 50) along the guides.
• phase A is represented the grip of the product
• phase B is an intermediate phase of transport
• phase C represents the release
• the controlled operation of the engine 22 makes that the support (S) (and therefore also the engine and the underlying group) can keep always the same inclination, making it rotate progressively with respect to the axis 26 that remains still (in the sense that it does not rotate but is dragged by the belts), thanks precisely to the bearing supports 26" ' .
• Figure 10 shows such a progressive rotation along the course so that the pick-up heads keep always a position orthogonal to the soil, but nothing would impede other inclinations.
• This group (20, 50) thus conceived allows to adjust the angulation of the pick-up heads in an extremely versatile manner.
• an electronic control system that coordinates the operation of the engine 34 and that of the engine 22.
• the engine 34 operates the belts and the controller receives a signal indicative of the position occupied by the group (20, 50) along the cam.
• the controller commands an operation of the engine 22 that, with a rotation of the axis thereof, for example progressive, controls the rotation of the plate S with respect to the axis 26, compensating the curvature of the cam and making that the pick-up heads can keep a constant pre-determined inclination during all the course.
• an inclination adjustment system of the pick-up heads that is automated and that allows to adjust and keep the inclination in a precise manner during all the course of the cam, further selecting any type of inclination.
• the motorized system 22 apart from being of easy construction, allows also to easily select a starting inclination to keep it during all the course. In this manner, also grips of containers of non-standard forms or having a handle can be easily made as well.
• Figure 7 shows for clarity purposes the assembly 20 to which the support 50 is connected for the pick-up heads .
• the pick-up heads are per se well known in the state of the art and are not the specific object of the present invention. Some of them are represented in a non-limiting manner in figures 8 and 9 and allow to grasp, for example, through sucking or through grippers systems or the like, various containers of various shapes.
• the heads are arranged on mobile stations provided with longitudinal movement placed on a single or double row, operated by pneumatic actuators and anyway with controlled operation.
• Such mechanism allows the pick-up heads to move apart, after making the grip of the product, before the insertion in the containers, so as to facilitate the operation of boxing.
• On the mobile positions are obtained the anchoring seats of the heads having such a shape as to be fitted without the help of utensils from the operator.
• the pick-up heads are organs that, adequately substituted and installed on the heads-holders, allow to box different types of products placed on a single or more rows. Further, they can be furnished with a rotation system around the own axis of all the pick-up head, or of one or more grippers with completion of longitudinal and transversal repositionings. This allows an extreme flexibility during the packaging phases. Further, the pick-up heads can be adapted also to products with pack grip such as bundles.
• the single grippers can be furnished with dedicated pneumatic actuator or an actuator can operate more grippers through the help of connection organs or transmission organs.
• the pick-up heads can be realized also with particular configuration suitable for the grip in the handle of the bottles.
• the support 50 to which the supports 53 of the pick-up heads are connected, is sliding also transversally with respect to the support 20 through a rail 51 and a further engine 52. In this manner, a transversal position can be further adjusted and this is well highlighted also in figure 10.
• the part considered extremely innovative for such patent application is represented by the coupling of the belt-pulley system (or equivalently chain-pinion) for the movimentation . of the group (20, 50) in combination with the motorized system to adjust the inclination of the pick-up heads.
• boxing machine is capable of great volumes of production and results to be of simple and economical realization. It satisfies fully the predominant need of flexibility and of adaptation to the different products to produce. Differences that can be present both as regards the product to box and as regards the container (box or case) inside of which the product has to be positioned. In fact, features of exceptional flexibility are required to allow the adaptation to containers and products (bottles, cans, bricks, etc.) with great diversity of height and size, with and without handle, of plastic material and non-plastic material, as well as configuration of packaging on a single or more rows .
• the belt movimentation system operated by engine allows a quick movimentation at low cost. It is enough in fact to send in movimentation the two belts to move the entire group.
• the maintenance costs are reduced to the minimum and often they are reduced to a quick substitution of the belt, preserving integrally the cams.
• the servo-motorized system that adjusts the inclination confers, always at a low consumption, an enormous flexibility.
• the conveyor belts 200 from which the collection is done and, on the opposite part, the belts 250 where the collected product is released.
• the second configuration (180°) is the standard one and allows to dispose the feedings of the products (bottles and boxes) on the line in a parallel manner, reducing significantly the encumbrance of the machine;
• the first configuration (90°) is used for products to box that suffer permanent deformations during the permanence thereof on the conveyor belt in movement.
• This last configuration permits to reduce significantly the problems both of manipulation and of quality of the products, easily subject to permanent deformations generated by the boxing process.
• the third configuration is the one that guarantees the greatest flexibility of production and the greater number of boxed products. In fact, the feeding on double row of the boxes allows, under a condition of single type of products to box, to execute the manipulation of a high number of boxes with reduced sizes of the machine.

• the adjustment in height of the center figure 12 allows to render the machine flexible with respect to any size of boxes or cartons to package since it allows to lift/lower the unload plan easily and quickly.
• the manual system with crank 301 or the automatic system 300 allows to lift and lower the high part 304 provided with two exiting pivots 305.
• Such exiting pivots 305 serve as support for the equipment of .figure 13.
• Such equipment is substituted at the moment of the substitution of the pick-up heads. In fact, it makes part of the components to be substituted on the machine when the type of product is changed. It is constituted by a series of pallets or hooks 302 arranged in a frame and that adequately operated allow to center the carton with respect to the deposit head.

Further, at the same time the ratiomotor 22 is operated, guaranteeing the perfect alignment of the pickup heads with respect to the worktop;
• the machine is provided with a software suitable for executing the operations described, of encoder, resolver. and systems of detection of the position, of electro-valves and actuators that contribute to the execution of the programmed phases.
• the engines used in the present invention are available in commerce and are per se not the object of the present invention. They are generally electric motors.
