Definitions

• the present invention relates to a system for creating a packaging line - for example for packaging pharmaceutical products or the like - comprising a series of machines designed to carry out, in succession, steps for packaging a product, said machines being inserted in a modular system made of steel structural work.
• Each of said packaging machines generally comprises a working surface to which the operating functional elements of the machine itself are applied.
• Said machines are generally designed and/or built by different firms according to respective standards, and consequently involve somewhat burdensome operations, since each time the construction is new and different, for them to be connected together and to the various facilities (electric power-supply lines or lines for driving the equipment, pneumatic lines, etc.) by means of frames for support and containment made of steel structural work.
• the purpose of the present invention is to simplify the above operations and to provide a modular structure made of steel structural work within which the various machines and the respective facilities are to be housed.
• Said structure once made known to the manufacturers of the packaging machines that are to form the line, makes it possible to connect the machines themselves up to one another and up to the various facilities according to preset criteria of modularity.
• each machine is considered as a casing structure defining a parallelepipedal space which, in plan an side vieww, has sides of a length equal to integer multiples of pre-set modules.
• the development in height comprises elements which are themselves modular, and affords the availability of technical spaces above the machines for housing facilities and appurtenances, such as control boards, electrical power-supply lines, and so forth.
• Each casing structure comprises frames that can be applied to the corresponding machines, the frames having a development mainly in a transverse vertical plane and having pre-set dimensions as chosen in a modular series.
• the adjacent structures for adjacent machines are connected together by means of said respective connecting frames. In this way, adjacent machines interface with one another by means of the respective connecting frames which, in so far as they are modular, can be easily joined together.
• each connecting frame is U- shaped with two side uprights rigidly connected at the bottom ends thereof by a cross member by means of welding or any other equivalent system.
• the said cross member is preferably contained within the thickness of the uprights of the respective connecting frame and is flush with said uprights at least on one side.
• the uprights and the cross members of said connecting frames preferably have a rectilinear pattern and a cross section which is preferably rectangular.
• the uprights and cross members of said connecting frames preferably have holes distributed along their development at a pre-set pitch. Said holes are designed to connect the frame - by means of screws or bracket anchors - to the operating part of the corresponding machine, namely to the working surface of the latter, and - by means of screws and possible spacers - to another connecting frame applied to an adjacent machine.
• the modular system made of steel structural work according to the invention may also comprise cross members of a modular length that are to be set between the connecting frames of a casing structure of a machine.
• the modular system made of steel structural work may moreover also comprise intermediate frames designed to be set between two end connecting frames of a corresponding casing structure and to be connected to said frames by means of said modular cross members.
• the function of said intermediate frames is to provide supplementary supports for machines of a considerable length.
• the conformation of said intermediate frames is similar to that of the connecting frames, i.e., with two side uprights joined together by a bottom cross member, and they are provided with resting feet in positions corresponding to the respective uprights.
• the rectangular cross section of the uprights of the connecting frames preferably has the length of the side orthogonal to the plane in which the frame lies equal to the length of a linear modulus (s), whereas in the uprights of the intermediate frames the corresponding dimension is twice as long (2s).
• the other dimensions of the section of the frames may be equal either to said linear modulus (s) or to twice said linear modulus.
• the system thus has a range of frames which differ from one another as regards the cross section of the respective uprights and which can be joined together at the uprights to form composite uprights having a cross section comprised in a square the side of which is 2 x (s).
• This possibility makes it possible to maintain modularity in the lay-out both for a line of aligned machines and for a line of machines with side branches.
• At least some of said connecting and intermediate frames may extend in height at least as far as a common surface for supporting working surfaces of the packaging line, said common surface being set, for example, at 90 cm from the machine-resting and operator-treading surface.
• top structures of the uprights of at least some of said connecting and/or intermediate frames there may be applied, for instance by means of screws, vertical extensions having a modular length, which in turn are connected together by means of modular cross members so as to form a top structure.
• Said structure is provided for containing parts of individual machines or of accessory frames of the latter, such as transparent or non- transparent guards, control boards, electrical facilities, pneumatic facilities or the like, or even ducting for the passage of electrical, pneumatic, lubrication, or suction lines, or the like, for supplying the various machines of the packaging line.
• the system made of steel structural work may comprise modular panels providing an enclosure for the boundary of the space occupied by the line.
• Said panels may be made of transparent or non-transparent sheeting, of sound-proofing material, or of any other suitable material, and have modular dimensions according to the dimensions of said connecting and intermediate frames and of the corresponding connecting cross members and vertical extensions.
• the system according to the invention therefore enables the manufacturers of the various packaging machines to know beforehand the boundary conditions that the machine that they have designed and produced is to meet, so avoiding subsequent problems of connection and interfacing and enabling the use of standard components, such as enclosure panelling, electrical switchboards, connectors for electrical and pneumatic lines, lighting and air-suction systems, sound-proofing systems and systems for technical separation of the processes, with ensured economic advantages and advantages in terms of quality.
