Cross-Reference to Related Applications
[0001] This application is a National Phase Application of PCT International Application No. PCT/IB2023/051808, having an International Filing Date of Feb. 27, 2023 which claims the benefit of priority to Italian Patent Application No. 102022000006707, filed Apr. 5, 2022, each of which is hereby incorporated by reference in its entirety.
Field of the Invention
[0002] The present invention relates to an operative connection device of a connection and fluidic distribution system.
Background of the Invention
[0003] Typically, connection and fluidic distribution systems are used within working environments, for example in the workstations of an assembly line. Such connection and fluidic distribution systems are used to supply pneumatically operated instruments, such as screwdrivers and/or inserters. Such connection and fluidic distribution systems are used to supply the same workstations or specific portions of the workstations, which in turn are considerable as pneumatically operated instruments.
[0004] Known connection and fluidic distribution systems comprise one or more rigid channels, for example in a line or in a ring, through which pressurized air flows. The term “air” refers to all types of gases or technical fluids, such as nitrogen, argon, mixtures of CO2, or similar, or industrial oils and the emulsions thereof. The term “pressurized air” refers to both positive pressure and negative pressure (that is, in depression/vacuum).
[0005] Such connection and distribution systems are intended to convey the pneumatic supply to said pneumatically operated instruments.
[0006] Moreover, it is known said rigid channels are arranged within raised regions, in such a way as to limit any encumbrance within the operative working regions.
[0007] In the prior art, in order to connect the channels to pneumatically operated instruments, specific connection groups extending vertically from above are used. Said connecting elements are also known in Italian jargon as “droppers”.
[0008] A typical problem with said connection groups is that of having complex, and above all inconvenient, modes of connection for the working means. In particular, this problem is mainly found at the terminal portions of said connection groups.
[0009] Sometimes two connection groups are arranged, one carrying pressurized air and one carrying air under negative pressure.
[0010] Sometimes, both a connection group for the supply of compressed air and a connection group for the supply of a cooling water-oil emulsion for a cutting tool are arranged, for example, in a machine or a workstation.
Summary of the Invention
[0011] The object of the present invention is to provide an operative connection device that is suitable for satisfying the requirements of the specific sector, thereby resolving the aforementioned problem.
[0012] This object is achieved by an operative connection device as described and claimed herein. Preferred embodiment variants involving further advantageous aspects are also described.
