Definitions
- the invention relates to an actuator for a step by step linearly movable stored component according to the preamble of claim 1.
- Actuators with which a torque is to be transmitted to a component are in a wide variety of embodiments for a wide variety of applications known.
- One area of application is, for example, the actuation of Slides or valve members in fittings are another area of application for example rotating pipe distributors, where a central pipe has a pivotable pipe section can be connected to a series of exhaust pipes can.
- From CH-645 703 A is also known an actuator for a step-by-step linear Movable component to be provided with a double-acting stationary at one end connected linear drive, with a controllable coupling with driver and a controllable stationary brake with driver, the driver in clamping Engagement with the component can be brought and the clamping device via a ring piston with cone on a ball system and a clamping cone for Holding the component works.
- the known device serves primarily to a wire to apply a tension. Larger when used on pipes The known device is relatively expensive in diameter, in particular when adapting to different pipe diameters. Even application the clamping force is not guaranteed.
- the invention has for its object an actuator for a gradual to create linearly movable pipe, in particular of larger diameter, which does not affect the pipe with controlled application of higher forces and who builds relatively small.
- the actuator according to the invention also sees a double-acting linear drive in front. This can be coupled to the pipe via the controllable coupling.
- the Control device controls the forward and return stroke of the linear motor and the Actuation of the clutch such that the clutch in one stroke direction of the Linear actuator is activated and released in the opposite stroke direction.
- the linear motor is not designed so that with a single stroke, the maximum or the desired adjustment path on the contrary, the linear motor is designed so that it has a stroke only makes a limited adjustment of the tube and the desired adjustment path for example, is only achieved after a larger number of strokes. This is necessary that during the return stroke after a working stroke the connection between the drive and the pipe is canceled. In this case the clutch solved. With a new working stroke, the clutch is activated so that the linear motor the pipe can in turn be adjusted by an increment.
- the invention Actuator is therefore a stepper motor, the step frequency and step length variable is.
- the step frequency is determined by the adjustment speed of the Linear motor and the stroke length.
- the stride length is determined by the stroke length of the linear motor.
- Both values can therefore be used within a wide range thanks to the linear motor to be changed.
- the actuator In the stepwise working according to the invention There is no adjustment limit for the actuator.
- the one according to the invention Actuator can move the pipe as far as desired.
- the invention Actuator also has the advantage that it is very precise a pipe in a certain position can bring.
- the linear drive is in the invention of a fluid-operated double-acting Adjusting cylinder formed, which is arranged parallel to the tube at a distance.
- the Coupling can also be actuated differently, for example by one Fluid, electromagnetic or electromechanical. It is advantageous if the The linear drive and the clutch are actuated by the same means.
- control for controlling the adjusting cylinder and the coupling there are different types of control for controlling the adjusting cylinder and the coupling conceivable.
- the adjustment cylinder can be equipped with an end position sensor be assigned, which in turn can be adjustable to reverse the stroke of the adjusting cylinder to control and at the same time the activation or release of the clutch.
- a timer can be provided, which reverses the stroke and the clutch controls.
- the control device according to the invention can also be a control program included, the stroke of the adjusting cylinder and the synchronous actuation of the Clutch controls.
- the driver component of the clutches is a clutch belt or a tether, which is placed around the tube and with the help of a short-stroke adjusting cylinder is either tensioned or loosened.
- the actuator according to the invention according to the invention is made up of simple parts and to manufacture with little effort. It is extremely robust and requires little maintenance. Furthermore, he builds very small and does not affect the pipe to be moved by controlled Forces are applied. When changing the pipe diameter only the tapes need to be replaced.
- a straight tube 100 is through passed through an opening in a wall 102.
- the tube 100 is from a coupling ring a clutch 104 surrounded by two parallel ring elements exists, which are connected by yokes 106.
- a clutch band 108 is arranged in the distance between the ring elements.
- the coupling ring is articulated at 110 the piston rod 112 of an adjusting cylinder 114, at 116 on the wall 102 is articulated.
- a cranked at the ends is supported Yoke 116 over spaced bearing points 118, 120 between the ring elements of the coupling ring on pipe 100.
- the yoke holds a short stroke Adjusting cylinder 122 and at the other end a fastening bolt 124 for the other end of the clutch band.
- the adjusting cylinder 122 pulls the clutch band 108 on, it loops tightly around the tube 100, so that when actuated of the adjusting cylinder 114, the tube is linearly advanced according to the stroke, for example in a position which is shown in broken lines in FIG. 2.
- a retaining ring is almost the same as the coupling ring, namely two spaced ring elements which are connected to one another via yokes 106.
- the adjusting cylinder 130 While of the working stroke of the adjusting cylinder 114, in which he the Moving pipe 100, the adjusting cylinder 130 remains unactuated to this movement not to interfere.
- the Adjustment cylinder 130 actuated so that the tube 100 in the assumed position remains and is not moved in the opposite direction. In this way the tube 100 can be continuously moved back and forth step by step.
- FIGS. 3 and 4 show a circuit diagram for the actuator according to FIGS. 1 and 2 shown for both possible directions.
- a solenoid valve 92 controls the pressurization of the adjusting cylinder 114 and a solenoid valve 94 the pressurization of the adjusting cylinder 122. Since the lines to the adjusting cylinder 122 are connected to the lines to the adjusting cylinder 114, determines the position of the valve 54 when the adjusting cylinder 122 is actuated.
- the Valve 92 is connected to a pressure medium source, not shown, for example Compressed air source, connected.
- a controller 146 is assigned to the valves 92, 94, which ensures an adjustment of the valves, in particular for the reversal of the stroke of the Adjusting cylinder 114.
- the controller 146 is, for example, with limit switch S1 and S2 for the adjusting cylinder 114, which are adjustable.
- the stroke reversal control can also be from a timer or part of a program be formed, by which the stroke of the adjusting cylinder 114 is predetermined, as well as the pressure, which is the speed of displacement of the displacement cylinder 114 certainly. If the adjusting cylinder 114 has ended the stroke described, that will Valve 92 switched. The valve 94, however, remains in the assumed position. The adjusting cylinder 114 therefore begins its return stroke. Now there is an exit depressurized by valve 94, clutch band 158 relaxed by drive 122.
