Definitions

  • the present invention relates to a safety switch of the type comprising on the one hand a housing in which is housed a block of electrical contacts, and on the other hand a control head fixed to the housing so as to take several differentiated positions by rotation around a first axis; in such a switch, on the one hand, the control head has at least one insertion slot for a actuator and on the other hand a transmission mechanism provided with an engaging roller by the actuator and capable of rotation about a second axis, perpendicular to the first axis, and a pusher intended to act on the contact block and mobile parallel to the first axis under the effect of the mechanism in response to displacement of the actuator.
  • An electromagnet the function of which is sometimes associated with such a switch consists in blocking the transmission mechanism, and thereby the actuator remaining attached to this mechanism, to allow remote locking control of the actuator and therefore of the organ - door or machine organ - that we want keep in a safe position.
  • switches see for example EP-553 885 and WO 95/18 457
  • the locking device must also be designed to absorb without damage from significant efforts from the actuator and to interfere as little as possible with the kinematic chain of transmission to the contact block.
  • the core of the electromagnet cooperates with the blocking by a locking device capable of being placed in two positions allowing the blocking of the pusher when the electromagnet is energized and respectively off.
  • the blocking member is preferably a guided locking slide in rectilinear slides of the housing perpendicular to the first axis and cooperating with the electromagnet core by an actuating ramp coupling reversible, for example a part with retoumable guide ramp.
  • the locking slide advantageously cooperates with a range of blocking provided on a metal sheath fitted on the tail of a linked pusher the roller of the transmission mechanism.
  • Figure 1 shows in elevation and in section a safety switch in accordance with the invention, configured as an interlock switch under voltage, in unlocked position.
  • Figure 2 is section 2-2 of Figure 1.
  • Figure 3 is a partial view of the safety switch of Figure 1, in locked position.
  • Figure 4 is section 4-4 of Figure 3.
  • Figure 5 shows the safety switch configured as a safety switch. locking off, in unlocked position.
  • the safety switch shown in the figures includes a housing 10 in which are housed an electrical contact block B and an electromagnet E.
  • the case is closed by a cover not indicated.
  • a control head 11 is fixed to the case so as to be able to take four different positions by rotation successive 90 ° around an axis X1.
  • the head 11 includes a lateral slot 12 and an upper slot 13 in one or the other of which one can introduce a actuator A of special shape in order to actuate the contacts of block B.
  • an actuator is for example attached to an envelope door or a machine body whose security requires closing or coming into a certain position, the contact block noting the safety position and translating it for example in an operating authorization. According to the case; he can be advantageous to engage the actuator A in the slot 12 or in the slot 13.
  • the control head 11 houses a transmission mechanism 14 provided with a roller running around an axis X2 perpendicular to X1 and a follower plunger 15; this mechanism is of any known type and is suitable, in particular by means of the form particular of the actuator and one or two locking rollers 14a of the rotating roller 14, which can be requested by the actuator, to prohibit any violation of the implementation of the contacts.
  • the plastic follower plunger 15 protrudes from the head towards the inside of the case, this pusher being linked to a follower head 19 which comprises a ramp 19a guiding a pin or axis of the roller to translate the movement of rotation of the roller in a translational movement of the pusher 15; this one acts directly on a control member 16 which is specific to the contact block B and who carries the contacts of it.
  • a sheath metallic 17 which does not participate in the transmission of movement to the block of contacts and which is intended to block the follower head of mechanism 14 when the order is transmitted to the coil of the electromagnet, while relieving the pusher of blocking efforts.
  • the sleeve can be slid on soft on the pusher while remaining free to move relative to it or can be held on the pusher by means of retaining, latching, and it is in stop at least in the locking phase on a shoulder 19b of the follower head to block it; it can be activated by an independent return spring, but, more simply, by connecting the follower head with the roller, a spring recall associated with it is sufficient to recall the assembly in the rest position.
  • the scabbard 17 has a length less than that of the pusher and has a bearing surface 18 for a locking member, as described below, this bearing being located at its lower free end or defined by a groove.
  • the electromagnet E comprises a movable core 20 movable in a direction X3 parallel to X1 and biased by a return spring F, the core being fixed to a support 21 for driving a slide 22; the support is movable in the housing 10 according to direction X3 and it is guided for this purpose in slides 23 of the housing, while the slide is movable in the housing in a direction X4 perpendicular to X1, X3 and is guided in rectilinear slides 24 of the housing.
  • a coupling piece retoumable 25 is engaged in a removable manner, for example snapped on or fitted into a grooved recess 21a of the support 21;
  • Exhibit 25 presents a ramp 26 cooperating with a follower finger 27 provided at the end 22a of the slide 22 opposite to that 22b which cooperates with the bearing surface 18 of the sheath 17.
  • the slide 22 has a fork 28 for blocking the sheath 17 without intervening on the pusher 15 (see FIG. 4).
  • the hitch retoumable provided between the electromagnet E and the pusher 15 can be arranged differently; in particular, the ramp may belong to the end of the slide and be driven by a finger of the support 21.
  • the support can be biased by a spring reminder shown schematically in the figures.
  • the actuator A is released from the control head 11 so that that the mechanism 14 is put in the rest state under the effect of a return spring not indicated and blocked in this state by a locking member not shown.
  • the pusher 15 and the metal sheath 17 are held in the low position by the connection of the follower head 19 with the rotating roller and the connection of the sleeve with the roller or pusher.
  • the member 16 of the contact block B is therefore held in position low and block B is in working position.
  • the electromagnet E is de-energized, so that the support 21 is put in the high position by the spring, which pulls the slide 22 to the left since finger 27 is housed towards the end of the left part 26a, for example vertical, of the ramp 26.
  • the sheath is therefore free, and with it the head 19 and the pusher 15, to move if the mechanism 14 is switched.
  • the spring F is an element of safety which, on interruption of the power supply to the solenoid coil, makes return the switch to its initial rest position (locked position for an electromagnet for locking under voltage or unlocked position for a solenoid power off).
