  • the invention is based above all on the idea that both the pistons in the working cylinders and the diverter valve should be monitored in their sequence of movements and should be reversed under computer control in consideration of the measured sequences of motion.
  • the pump-side hydraulic connections of the drive cylinder and the reversing cylinder of the pipe switch are arranged in parallel branches of a supplied by the reversing pump hydraulic circuit, that the pipe switch has a responsive to their pivot position encoder that at least two im Distance from one another on the drive cylinders arranged on the passing piston of the drive cylinder responsive cylinder switch sensors and / or provided on the pressure curve at the high pressure output of the Reversierpumpe responsive pressure sensor are provided, and that the computerized Um Kunststoff on output signals of the position sensor on the one hand and on output signals of the cylinder shaft sensors and / or the pressure sensor, on the other hand, has an appealing control routine for a program-controlled activation of a control element for adjusting the flow rate and direction of the reversing pump
  • a further preferred embodiment of the invention provides that the control member is formed by a swash plate of the reversing and that the swash plate is actuated hydraulically or electromechanically.
  • the reversing member of the pipe switch can be configured, for example, as an electromagnetically or hydraulically controllable directional control valve.
  • the pivot position of the pipe switch is measured that monitored during the conveying process, the position of the piston in the drive cylinders and braked in an end portion of each piston stroke, the piston speed by reducing the delivery of the reversing pump delivery rate and the piston is driven to the end stop at a low speed, that the pressure supply to an actuator of the transfer tube is reversed and the delivered by the reversing pump in an increase phase flow rate without reversal is increased until the transfer tube has reached a defined intermediate position on their pivoting, that then the delivered by the reversing pump flow rate is reduced until the pipe switch reaches an end stop, and then reversed the direction of flow of the reversing and Druc kzucht to the pipe switch via a reversing device interrupted or maintained by reversing.
  • a preferred embodiment of the invention provides that in the final flow reversal of Reversierpumpe connected to the transfer tube hydraulic Um Kunststofforgan is reversed or locked.
  • the reversing pump can be briefly controlled in the increase phase during the Um Kunststoffvorgangs to maximum delivery quantity.
  • the delivery cylinders 50,50 ' are driven in a push-pull manner via hydraulic drive cylinders 5,5' and a reversible hydraulic pump 6.
  • the delivery pistons 60, 60 'of the delivery cylinders 50, 50' are connected to the pistons 8, 8 'of the drive cylinders 5, 5' via a common piston rod 9, 9 '.
  • the drive cylinders 5,5 ' are in the embodiment shown on the bottom side via the hydraulic lines 11,11' of the hydraulic circuit with the help of the reversing pump 6 pressurized oil and are at their rod side End hydraulically connected to each other via a swing oil pipe 12.
  • the direction of movement of the drive pistons 8,8 'and thus of the common piston rods 9,9' is thereby reversed, that the flow direction of the reversing pump 6 is reversed via a reversing device 18 containing a computer 14 and an adjusting mechanism 16.
  • the reversing pump 6 has a swash plate 62, which is swiveled through its zero position during the reversal, so that the conveying direction of the pressure oil in the hydraulic lines 11, 11 'is reversed.
  • the delivery rate of the reversing pump 6 can be varied by the swivel angle of the swash plate 62 at a predetermined speed of the drive motor, not shown.
  • the swivel angle of the swash plate 62 can be adjusted via a remote control device 64 with the assistance of the computer 14.
  • the reversal of the reversing pump 6 and the diverter 56 takes place as soon as the pistons 8, 8 'of the drive cylinders 5, 5' reach their end position.
  • the reversing device utilizes output signals of each of the rod-side and bottom ends of the two drive cylinders 5,5 'arranged Zylinderschaltsensoren 20,22 and 20', 22 ', which are the output side connected to the computerized reversing device 18.
  • the cylinder switch sensors respond to the drive piston 8,8 'passing by during the pumping operation and signal this event to the computer inputs 66,68.
  • a reversing signal is triggered with a time delay in the reversing device, which reverses the reversing pump 6 via the adjusting mechanism 16.
  • the reversing device 18 further includes a pressure sensor 24 which is connected to the high-pressure side 78 of the reversing pump 6 and whose output signal is evaluated in the computer 14 by means of a pressure monitoring routine.
  • the pressure monitoring routine calculates a medium high pressure in the course of a lifting operation and comprises an algorithm for determining a pressure increase occurring at the end of each delivery stroke and for converting it into a reversing signal for the reversing pump 6 and / or the diverter 56. This reversal signal is preferred in the event of failure of the Cylinder switch sensors 20,20 ', 22,22' used for reversing.
  • a special feature of the invention is that the diverter 56 has a responsive to their pivot position encoder 80, and that the computerized reversing device 18 to the output signals of the position sensor 80 and the output signals of the cylinder switching sensors 20,20 ', 22,22' and / or the pressure sensor 24 responsive control routine for a programmatic control of the swash plate 62 of the reversing pump 6 and arranged in the hydraulic branch 82 of the pipe switch 56 Um
  • the position sensor 80 is designed as an angle encoder, while the reversing member 79 is formed as an electromagnetically controllable directional control valve.
  • the pipe switch 56 can be acted upon in dependence on their angular position with hydraulic oil, so that a rapid, but still steamed recirculation takes place.
  • a delay line x is first waited depending on the flow rate or stroke time x until the swash plate 62 of the reversing pump 6 is driven.
  • the delay results in a ramp R in the flow rate, which leads to a deceleration of the piston 8,8 '.
  • the piston is at the cylinder bottom.
  • the swash plate 62 pivots again fully in a pushover phase P, so that a pressure is built up in the previous feed direction that sets the diverter 56 in motion from its starting position A.
  • the pipe switch exceeds a predetermined intermediate position Z, which is signaled by the position sensor 80, the swash plate 62 is swung back again.
  • the method described is particularly advantageous for single-circuit two-cylinder thick matter pumps, in which the pump-side hydraulic connections of the drive cylinder and the reversing cylinder of the pipe switch are arranged in parallel branches of a hydraulic circuit fed by the reversing pump.
