Definitions

  • This invention concerns a compressed-air distributing device and in particular a subbase with sectional modular elements for feeding and supporting pneumatic or solenoid control valves for apparatuses utilizing compressed air.
  • subbases with modular sectional elements have also been proposed, in which two or more distributing elements are connected in series in order to form a subbase with any given number of seat- inga for valves relative to any given number of utilizing apparatuses.
  • sectional subbases currently in use fulfill the purpose for which they were designed, there still remains the problem of their structural simplification and matchability, in addition to the problem of a satisfactory liquid seal.
  • a scope of this invention is therefore to provide a modular sectional distributing unit for forming subbases for distributing compressed air and for supporting control valves, which is provided with an extremely simple but at the same time extremely efficient connecting system, capable that is, of ensuring a satisfactory airtight seal between adjacent distributing units, and which is also suitable for use in pneumatic circuits operating at relatively high pressures, equal to or over ten Bars.
  • a further scope of this invention is to provide a subbase with sectional distributing units, as specified above, in which the individual distributors are provided with simple coupling means to permit a rapid assembly and which ensures the utmost rigidity and stability of the assembled subbase.
  • each distributing unit is provided with a main duct arranged along the longitudinal axis of the subbase, between lateral surfaces defining the interfaces of adjacent distributing units, and connecting means for firmly and tightly securing two or more distributing units together, characterized by the fact that the connecting means comprise, in correspondence with the aforesaid interfaces, pivot means situated on one side of the main duct, and at least one locking member on the opposite side of the aforesaid duct, said locking member acting in order to exert a clamping force between the interfaces of adjacent distributing units, which force slopes towards and forms an angle with the longitudinal axis of the main duct.
  • the pivot means between adjacent units are in the form of simple pins on one of the interfaces, which fit into appropriate seats on the corresponding interface of an adjacent distributing unit, whilst the locking member consists of a simple slanting screw, capable of exerting a thrust action in the direction of the hinge pins and at the same time of shifting the point of application of the clamping force as close as possible to the main duct axis, thereby permitting a better fluid seal.
  • each lateral interface between adjacent distributing units presents a first flat surface portion arranged on a plane at right angles to the axis of the main duct in correspondence with the pivot pins, and a second flat surface portion, parallel to and spaced apart from the first surface portion, arranged at the end of an intermediate sloping portion, in correspondence with which is situated the locking member.
  • Figure 1 shows a generic subbase 1 for supporting and feeding air to a number of apparatuses or devices utilizing compressed air, more generically referred to as "utilizers”, through pilot valves or solenoid valves 2, only a few of which have been shown.
  • the subbase 1 is therefore made up of modular sectional distributing units 3, equal in number to the valves to be fed, the overall structure of which is shown in the remaining figures.
  • each distributing unit is delimited on two sides by surfaces or portions of flat surfaces defining, with reference to the figures, a lower face 4 for anchoring to the subbase 1, and an upper face 5 supporting the valves 2, provided with a central aperture 6 permitting communication between the inlet of a valve 2 and respectively, a main duct 7 of the distributing unit.
  • Each distributing unit 3 is moreover delimited, on the two interfaces of adjacent units, by flat surfaces or surface portions lying in planes parallel to each other and at right angles to the longitudinal axis of the main duct 7 which is tightly connected to the main ducts of the following or preceding units and co-operates in defining the entire air-distribution duct in a subbase made in this way.
  • each of the interfaces of the distributing units comprises a first flat surface portion 10a and 10b on which open out the ends of the main duct 7, and a second flat surface portion 11a and 11b, arranged parallelly to and at a certain distance from the first ones, at the end of a sloping surface portion,12a and respectively 12b, for the purposes pointed out further on.
  • a gasket 13 is situated in an appropriate seating on the surface 10b, to form an air seal in correspondence with the main duct 7.
  • Each distributing unit 3 is completed by interconnecting means in order to permit quick and easy assembling and disassembling of the individual distributing units, with or without the valves assembled.
  • the aforesaid interconnecting means substantially comprise pivot means situated on one side of the main duct, which in the case of the example shown, consist of a pair of pins 14 on the surface 10b, protruding parallel to the axis of the main duct 7, which pins fit into a corresponding pair of holes or seats 15 on the surface 10a of the adjoining distributing unit, as shown schematically in figures 5 and 7.
  • the aforesaid interconnecting means comprise, moreover, a clamping member situated on the side of the duct 7 opposite that of the centering and pivot means 14; such locking member may be made in any way as long as it is able to provide a clamping force which is inclined with respect to the longitudinal axis of the main duct 7 of the distributing unit, that is to say, to create a crosswise force between one unit and the other, having its action point as close as possible to the longitudinal axis of the duct 7.
  • the locking member is in the form of a screw 16 which screws into a threaded hole 17 in the sloping surface 12a of each unit, so that its axis forms an angle ranging between approximately 12 and 18 degrees with the axis of the duct 7; the screw 16 lies on an intermediate plane between the hinge pins 14 and comprising the axis of the duct itself, so as to create an even distribution of the clamping pressures on the interfaces.
  • the fastening screw 16 engages with a fork-shaped part 18 on the opposite side of an adjacent unit, positioning the head of the screw to the rear of the arms of the fork 18.
  • a tooth or protrusion 19 beneath the screw hole 17 comes to rest between the arms of the fork 18 and co-operates with the pins 14 to ensure that the various distributing units are and remain firmly secured and complanate to each other.
  • the various distributing units 3 are assembled together to form a subbase of any desired length, in the following way: with reference to the example in the accompanying drawings, as shown in figures 2 and 6, two adjacent distributing units are placed close together and the fork -shaped end 18 of one unit is fitted onto the screw 16 of the other by making them slide reciprocally along the interfaces 10, 10b until the pins 14 of the first unit are aligned with the holes 15 of the other unit. At this point, the pins 14 are inserted into the corresponding holes, bringing the gasket 13 gently into contact with the peripheral edge of the main duct 7 of the adjoining distributing unit and making the opposing faces 10a and 10b of the two units touch in the area of the centering and pivot pins.
  • the locking system clearly offers numerous advantages in subbases of the aforementioned type, thanks to the particular sloping disposition of the clamping force exerted by the screw 16 or by any other suitable device, in that this inclination makes it possible to create a point of articulation, even by means of simple axial pins, and at the same time bringing the point of application of the force close to the fluid duct, that is to say, in the area where the seal is of the utmost importance; moreover, apart from permitting its easy insertion into the fork-shaped end of the adjacent unit, the sloping disposition of the screw also offers operational simplicity by making use of a simple screwdriver which can be easily operated from one side without interfering with the individual units of the subbase.
