Definitions

  • the present invention relates to a joint for transmitting and distributing electric power, electric signals, several pressurised fluids, particularly adapted for connecting the relatively-moving parts of machines for calibrating and smoothing stone materials, ceramics, marble, granite, in addition to machines for working glass and wood.
  • a joint for transmitting and distributing electric power and electric signals, between at least two relatively-moving parts, falls within the following International Patent Class (IPC): H01R - ELECTRICALLY-CONDUCTIVE CONNECTIONS; STRUCTURAL ASSOCIATIONS OF A PLURALITY OF MUTUALLY-INSULATED ELECTRICAL CONNECTING ELEMENTS; COUPLING DEVICES; CURRENT COLLECTORS.

  • Object of the present invention therefore is providing a new combined joint for transmitting and distributing electric power, electric signals, in addition to several pressurised fluids, particularly adapted for connecting relatively-moving parts of machines for calibrating and smoothing stone materials, ceramics, marble granite, in addition to machines for working glass or wood.
  • a rotary joint is integral with the chassis of a machine or machinery (M) by means of a fixed structure and a rotary structure.
  • the fixed structure is composed of an upper flange (4) and a lower flange (5), both keyed to the internal surface of a very thick cylinder (6).
  • the upper flange (4) houses interface holes in which bolts (7) are inserted, for joining the fixed structure with respect to the carrier chassis of the machine (M).
  • the rotary structure is composed o fan upper cylindrical body (8) and a lower cylindrical body (9), both keyed onto the external surface of a hollow cylinder (10).
  • the hollow cylinder (10) houses both the apparatus for distributing compressed air, and the apparatus for distributing electric power, as demonstrated from the following description in this specification.
  • the rotary structure is coaxial with the fixed structure; bearings (30) and (31) are respectively keyed onto the upper (8) and lower (9) cylindrical bodies and then onto the fixed cylinder (6); at the same time, sealing rings (33) and (34) are installed, as guarantee of the hydraulic seal between the relatively-moving parts.
  • a first delivery pipe of the compressed air (11) is fastened through an upper plug (14) and a lower plug (13) to the ends of the hollow cylinder (10).
  • the upper plug (14) connects the first delivery pipe of the compressed air (11) to a pneumatic joint (17).
  • the lower plug (13) connects the first delivery pipe of the compressed air (11) to the pneumatic circuit of the operating heads of the machine, by means of an angular fitting (15).
  • a second delivery pipe of the compressed air (12) is fastened by means of the upper plug (14) and the lower plug (13) to the ends of the hollow cylinder (10).
  • the upper plug (14) connects the second delivery pipe of the compressed air (12) to a pneumatic joint (18).
  • the lower plug (13) connects the second delivery pipe of the compressed air (12) to the pneumatic circuit of the operating heads of the machine, by means of an angular fitting (16).
  • a preferred variation of execution of the assembling of the delivery pipes (11) and (12) for the compressed air provides the pipe (12) contained in the pipe (11), the two pipes being assembled coaxially.
  • a series of annular sliding contacts (21) are keyed, onto which brushes (22) are pressing, such brushes (22) being composed of elastic metallic elements projecting with respect to a plate (23) supported by a supporting structure (24), which is fastened, through screws, to the carrier structure of the machine (M).
  • each end of the brushes (22) fastened to the plate (23) is equipped with respective terminals (25) (not shown); a series of electric cables with a large section (26) (not shown) and a small section (27) (not shown), connects said terminals (25) to respective connectors through which high-intensity power passes, and the terminals corresponding to the connection for the low-intensity power flow.
  • a shunt box (60) (not shown) comprises a receptacle in which said connectors are housed.
  • the hollow cylinder (10) has, keyed onto its own external diameter, a toothed pulley (40) connected through a toothed belt (41) to a toothed pulley (42) which is integral with a measuring device (43) of the angular position assumed by the hollow shaft (10) with respect to the fixed structure of the machine (M).
  • Said measuring device (43) generates an electric signal proportional to the relative movement impressed by the above described belt-type transmission.
  • An electronic control logic detects and processes said electric signal defining an angular position.
  • the volume (50) included between the fixed cylinder (6) and the rotary hollow cylinder (10) is a passage of large water flow-rates coming from the entry hole (51) obtained in the side part of the cylinder (6) and directed towards the outlets (52) radially obtained on the lower rotary cylindrical body (9).
  • the volume (70) included between hollow cylinder (10) and the two delivery pipes of the compressed air (11) and (12) is occupied by the electric cables connected to the annular sliding contacts (21) and directed towards the respective electric motors of the smoothing and polishing heads, crossing the passages (71) obtained in the lower end of the hollow cylinder (10).
  • the joint for transmitting electric/electronic power and hydraulic/pneumatic power described in this specification satisfies the purpose of combining different types of transmissions of power in a single device.
