Definitions

  • the present invention relates to a method for reducing the mechanical load and to increase the switching speed during the actuation of a control piston, in particular of the control piston of a switching element, according to the preamble of patent claim 1.
  • the switching elements are first vented to actuation on the opposite side. As soon as the pressure is applied for the desired movement, the opposite side is vented; In this case, the end stop is damped by the air cushion and the dynamic pressure resulting from the movement and the mechanical load is reduced. To realize this concept, different devices are known from the prior art.
  • DE 197 02 948 C2 describes a valve arrangement having a main valve which has a feed channel which can be connected to a pressure medium source, a working channel which can be connected to a consumer and a movable valve member which controls the fluid connection between the feed channel and the working channel, wherein the valve member has an application surface is associated, which is acted upon for moving the valve member with a fluid under pressure under a pilot fluid, which is fed via a supplied from the pressure medium source and controlled by a pilot valve pilot control channel.
  • pilot channel serving for specifying the operating pressure pressure regulator is switched on and the valve member associated with one of the loading surface axially oppositely directed Jacobeckungs realization which is acted upon by a counter-pressure channel with the prevailing operating pressure in the working channel.
  • DE 101 56 099 B4 describes a control device for pressure-actuated pneumatic actuators of valves, with a housing, with a pressure medium supply line, with a pressure medium discharge, a vent, and with a control piston, which is guided in a cylinder bore, and piston discs, through which the Cylinder bore is divided into control chambers, wherein for displacing the control piston from a first switching position into a second switching position and vice versa one of the control chambers by means of a control means pressurized or vented, depending on the switching position of the control piston, the pressure medium discharge either with the pressure medium supply line or the vent is connected by one of the further control chambers.
  • the one control chamber for venting with the vent is connectable and the control means is arranged in the housing.
  • the present invention has for its object to provide a method for reducing the mechanical load and to increase the switching speed in the operation of a control piston, in particular of the control piston of a switching element, by the implementation of a fast piston movement is achieved with sufficient cushioning.
  • the duration and amplitude of the counter-ventilation pulse are defined such that a faster piston movement can be achieved with sufficient end-position damping that can be achieved at the same time.
  • the counter-ventilation pulse can, shortly before the actuation of the control piston, i. be generated shortly before the energization of the valve of the target position and be switched off when energizing the valve of the target position or remain overlapping for a certain time.
  • the time interval between the beginning of the counter-ventilation and the beginning of the energization of the valve of the target position can be adjusted according to the invention as a function of the desired damping and switching speed.
  • the time, duration and / or amplitude of the counter-ventilation pulse depend on the cylinder type (differential cylinder, synchronous cylinder, 2-position cylinder, 3-position cylinder); In the case of a differential cylinder, the time, duration and / or amplitude are also dependent on the direction of movement and, in the case of a 3-position cylinder, on the starting and ending position. Type and duration of the counter-ventilation pulses may also depend advantageously on a requested switching speed (eg power circuit, Schonsctreu etc.).
  • the switching on and / or off of the counter-ventilation pulse can be carried out event- and / or time-controlled.
  • the switching times are shortened, with a sufficient, variable end position damping is realized.
  • Another advantage is that the valves required for the counter-ventilation can be made smaller, whereby the power consumption is reduced.
  • Figure 1 is a schematic representation of a control piston and the pressure lines and vent connections
  • Figure 2 shows an exemplary course of the signal of the valve for counter-ventilation and the signal of the valve for the target position of the piston and
  • Figure 3 shows another exemplary course of the signal of the valve for counter-ventilation and the signal of the valve for the target position of the piston according to the invention.
  • a control piston 1 is shown, which is arranged axially displaceably in a shift cylinder 2; the possible adjusting movement is illustrated by the arrow. 3, 3 'are pressure lines and designated 4, 4' vent connections.
  • the duration and amplitude of the counter-ventilation pulse is defined such that the maximum possible ventilation pressure, which limits the piston speed, can not build up.
  • the switching speed e.g., power switching, switch-off, etc.
  • the end position damping can be adjusted.
  • the time, duration and / or amplitude of the counter-ventilation pulse are dependent on the cylinder design.
  • the opposite side is vented only after the beginning of the pressurization of the switching piston or the energization of the valve of the target position by means of a counter-ventilation pulse to set a defined damping.
  • the time interval between the beginning of the energization of the valve of the target position and the beginning of the counter-ventilation in dependence on the desired damping and switching speed is adjustable.
  • FIG. 3 illustrates the case in which the counter-ventilation pulse is generated shortly before the actuation of the switching piston, ie shortly before the valve is energized, and is kept overlapping for a specific time.
  • the time interval between the beginning of the counter-ventilation and the beginning of the energization of the valve of the target position can be adjusted according to the invention as a function of the desired damping and switching speed.

Abstract

Dans le cadre du procédé de réduction de la charge mécanique et d'augmentation de la vitesse de commutation lors de l'actionnement d'un piston de commutation, notamment du piston de commutation d'un élément de commutation, le côté du piston de commutation (1) à l'opposé de la pression de commande est ventilé de manière définie au moyen d'une impulsion de ventilation contraire de telle sorte que la pression de ventilation maximale possible dans le cylindre de commutation (2) ne puisse pas s'établir, la durée et l'amplitude de l'impulsion de ventilation contraire étant définies de telle sorte qu'il est possible de réaliser un mouvement rapide du piston tout en obtenant simultanément un amortissement suffisant en fin de course.
