Definitions

  • the speed of a double-acting pneumatic cylinder is adjusted for each direction of travel using a unidirectional flow limiter placed between the orifice of the cylinder through which air escapes during the set stroke and its distributor. power supply.
  • a unidirectional flow limiter placed between the orifice of the cylinder through which air escapes during the set stroke and its distributor. power supply.
  • Such an apparatus also called an adjuster, comprises an adjustment screw integral with a needle to limit at will the flow of exhaust air through its seat which thus determines the speed of the jack.
  • the regulator furthermore comprises a one-way valve opening in the direction of the intake flow rate and closing in the direction of the exhaust flow. This is how the unidirectional flow limiters described in document FR-A-2343280 operate.
  • the present invention makes it possible to achieve this object, by producing two-speed adjusters, the transition from one speed to a second set lower speed being effected by the arrival in the device of a pneumatic piloting signal. , and the reverse operation by the disappearance of this signal.
  • a pilot-operated fitting-regulator for adjusting the speed of pneumatic cylinders is mounted between a jack and its distributor, which fitting-regulator comprises a adjustment moving axially in a cylindrical housing of a body, and one end of which forms a needle cooperating with its seat to control the passage of the fluid from a first chamber delimited by an orifice connectable to the jack and said seat to a second delimited chamber by said seat and an orifice connectable to the dispenser;
  • the adjusting element is a piston comprising at least one seal ensuring it a sealed sliding, and which delimits a third chamber with an orifice for connection to a pipe by which a pressure signal acting acting on the face of the piston opposite the needle and driving it towards the closing of the seat, the stroke of the piston in closing of the seat being determined by a stop adjustable axially in position from the outside and on which it abuts by its end on the needle side.
  • a pilot-operated fitting-regulator comprises three connectable orifices; the first to one of the orifices of the jack through which the air leaves in the direction of travel whose speed is to be adjusted; the second to the corresponding orifice of the distributor, and the third to a pilot piping.
  • the air escaping from the jack during the race flows from the first to the second orifice and its flow rate through the seat is a function of the position of the needle which controls its passage.
  • the signal in the third chamber has the effect of moving the piston in the direction of the seat, and this stroke being limited by the internal end of the maneuverable stop from the outside on which it abuts by its needle end, the flow rate left at the exhaust air passing through the device, and therefore the speed of the jack, thus depends on the setting of this screw.
  • the stroke of the piston in opening the seat can also be limited by a second adjusting screw opposite the first, on which it abuts by its end opposite the needle: this second screw regulating a speed cylinder always higher than that set by the first which determines the passage through the seat in the presence of a piloting signal.
  • a return valve is arranged in bypass of the seat to open in the direction from the air intake to the cylinder and close in the direction of the purge flow from it.
  • the piloted adjuster comprises in a body 1, a piston 2 sliding in a cylindrical housing in a sealed manner by a seal 3, and one end of which forms a needle 15 cooperating with a seat 16 to control a flow of fluid coming from a first chamber 4 to a second chamber 5.
  • the first chamber 4 is delimited by the seat 16, an annular unidirectional valve 14 established in derivation of said seat, the joint 8 of an adjustment screw 7, and by a orifice connection 11.
  • the second chamber 5 is delimited by the seat 16, the valve 14, the seal 3 of the piston 2 and a connectable orifice 12.
  • the valve 14 is oriented so as to close at the flow of fluid flowing from chamber 4 to chamber 5 and opening in the opposite direction.
  • the adjuster also comprises a third chamber 6 delimited by the seal 3 of the piston 2, a plug closing the housing of said piston, the seal 10 of an adjustment screw 9 in the plug 1a and a connectable orifice 13.
  • the piloted regulator regulates the low rod exit speed of a jack 30, by the effect of a piloting signal, emitted by a sensor 50.
  • the air coming from the chamber purge cylinder, rod side flows into the adjuster from its orifice 11 to its orifice 12, closes the valve 14 at its own passage which can only be done through the seat 16 with a flow rate depending on the position of the needle 15.
  • the chamber 6 being under pressure, the piston 2 is pushed into abutment on the internal end 7a of the screw 7 which passes through the seat 16 in order to penetrate into a blind axial channel of the piston 2 and to improve its guidance.
  • the speed of the jack 30 is therefore adjusted by the screw 7.
  • the piston 2 In the absence of this signal, the piston 2 is held in the open position of the seat 16 by the effect of the pressure passing through l device in the chamber 5. The passage left to the exhaust flow through the seat 16 is then a function of the adjustment of the screw 9 on the internal end of which abuts the piston 2 by its face opposite the needle 15. The screw 9 therefore sets a jack speed always higher than that set by screw 7. The jack making its reverse stroke, the intake air passing through the adjuster from port 12 to port 11 opens the valve 14 and the full flow is thus ensured, whether the piloting signal is present or not at the orifice 13 and independently of the adjustment of the screws 7 and 9.
  • the sensor 50 can be operated either manually or by the rod of the jack 30 itself, or that of another cylinder.
  • the signal can also come from various sources, such as a timer, the start of another cylinder, sequencer, etc. It can only be issued for certain cylinder operating sequences in the cycle.
  • Figure 2 is the sectional representation of another embodiment of the invention which differs essentially from the embodiment previously described according to Figure 1, by its piston 2 which has two different sections defined by the seals 3 and 3a that door.
  • the seal 3a of larger diameter than that of the seal 3 is subjected to the pressure of the signal in the chamber 6; this arrangement allowing a possibly low pressure control signal.
  • Figure 3 is the sectional representation of another embodiment of the invention which, like the embodiment previously described according to Figure 2, comprises a stepped piston 2 capable of moving under the effect of a low pilot pressure.
  • the needle 15 of the piston 2 is extended by a rod 2a of small diameter which passes through the seat 16 and has at its end a piston section defined by its seal 3b weaker than that of the seat and that of the large section of the piston defined by the gasket 3.
  • the pressure passing through the device acts on the piston 2 in the direction of the opening of the seat 16 with a force resulting from the difference in sections 3-3b, while the opposing pressure of the signal acts on the full section 3.
  • the adjusting screw 7 of the low speed on the internal end of which abuts the piston 2 by its small section has no seal.
  • FIG. 4 is a sectional representation of another embodiment of a two-speed pilot-operated fitting-regulator according to the invention.
  • the arrangement of the piston 2 is here such that it tends to close the seat 16 in the direction of flow. exhaust air, that is to say from chamber 4 to chamber 5: this arrangement is more particularly applicable in devices of small bulk.
  • the adjusting screw 7 of the low speed has a screw thread on the left and the adjusting screw 9 for high speed, a screw thread on the right.
  • the orifices 11, 12 and 13 are equipped with instantaneous connection cartridges 11a, 12a, 13a.
