Definitions

  • the invention relates to a device for filling a container, a filler with several filling devices and a method for operating a filling device.
  • a filler for filling the containers can be included.
  • the filler can have at least one filling station or device for filling the containers.
  • the device can have a throttle valve for adjusting a flow rate during filling and a filling valve downstream of the throttle valve for dispensing the filling material to the container.
  • the throttle valve can be controlled pneumatically or by an electric motor, for example.
  • the WO 2018/141558 A1 describes a device for filling liquid or flowable contents into packaging, comprising a tank, a filling device with a filling valve, a line that connects the tank to the filling device and a throttle valve that is arranged in the line between the tank and the filling device.
  • the throttle valve has a variable flow cross section.
  • the throttle valve has an actuator for adjusting the flow cross section.
  • the actuator is used to change the valve position and can, for example, include a pneumatic actuation unit.
  • a disadvantage of a pneumatic drive of a throttle valve can be that in practical applications it is limited to a limited number of positions that can be approached if precise, reproducible accuracy is required.
  • An electric actuator can be disadvantageous in that it is not suitable for filling goods with pulp, pieces, etc. due to a small valve member travel or stroke and it only closes relatively slowly.
  • the invention is based on the object of creating an improved device for filling a container, with which the disadvantages mentioned can preferably be at least partially overcome.
  • the device should preferably be used to process both pulp-containing (piece-containing/fiber-containing), liquid filling goods and pulp-free (piece-free/fiber-free), liquid filling goods, e.g. B. silent or carbonated, can be filled without having to compromise on filling speed.
  • the device has a filling valve for discharging a (e.g. liquid or pasty) filling material into the container (e.g. in a state pressed against a container mouth of the container).
  • the device has a throttle valve for adjusting a flow rate of the filling material, the throttle valve being arranged upstream of the filling valve.
  • the throttle valve has a valve member for adjusting a flow cross section of the throttle valve.
  • the throttle valve has a pneumatic drive which is in operative connection with the valve member for moving the valve member.
  • the throttle valve has an electric drive which is in operative connection with the valve member for moving the valve member.
  • the device can advantageously enable the advantages of an electrical control of the throttle valve and the advantages of a pneumatic control of the throttle valve to be linked with one another.
  • the electric drive can be used, for example, to adjust the flow rate for clear filling goods or products without pulps, fibers or pieces.
  • a closing function e.g. to completely or partially close the throttle valve
  • the pneumatic drive can be used particularly advantageously to provide power support to the electric drive, e.g. B. with carbonized filling products with increased filling pressure.
  • the lower current consumption can also be particularly advantageous, since, for example, less current has to be transmitted to a rotating part of a rotary filler, which also means that a less structurally complex slip ring transmitter or similar can be provided.
  • the pneumatic drive can preferably be a pneumatic cylinder-piston drive.
  • the electric drive can preferably be an electromechanical, electromotive, electromagnetic or piezoelectric drive, e.g. B. stepper motor.
  • the pneumatic drive e.g. a piston and/or a pressure chamber of the pneumatic drive
  • the pneumatic drive can therefore advantageously be operated alone on the one hand and in combination with the electric drive to move the valve member on the other hand.
  • the pneumatic drive and the electric drive can be decoupled from one another and coupled to one another.
  • the valve member can only be moved by the pneumatic drive and not by the electric drive, e.g. B. for the locking function.
  • the coupling can advantageously enable joint operation of the electric drive and the pneumatic drive, e.g. B. to relieve the load on the electric drive.
  • the pneumatic drive has a pressure chamber, which can be acted upon with compressed air, and a (e.g. one-piece or multi-part) piston in operative connection between the valve member and the pressure chamber.
  • a piston of the pneumatic drive can limit the pressure chamber. This advantageously enables a reliable implementation of the pneumatic drive, which can advantageously be connected to the electric drive in order, for example, to operate both drives in combination or to operate only the pneumatic drive.
  • the piston of the pneumatic drive can be moved independently of the electric drive. In this way, a movement of the valve member can advantageously be brought about by operating only the pneumatic drive.
  • the piston of the pneumatic drive can be pushed and/or supported by the electric drive. In this way, a movement of the valve member can advantageously be brought about by a joint operation of the pneumatic drive and the electric drive or only by operation of the electric drive.
  • the electric drive has a piston, which is preferably movable by a spindle nut of the electric drive. This advantageously enables a reliable implementation of the electric drive, which can advantageously be connected to the pneumatic drive in order, for example, to operate both drives in combination or to operate only the electric drive.
  • the piston of the electric drive can be brought into operative connection, preferably into physical contact, with the piston of the pneumatic drive in order to push and/or support the piston of the pneumatic drive.
  • the piston of the pneumatic drive and the piston of the electric drive have opposite contact surfaces for mutual contact.
  • the valve member and the piston of the electric drive are arranged at opposite ends of the piston of the pneumatic drive.
  • the piston of the pneumatic drive can be moved independently of the piston of the electric drive.
  • the piston of the pneumatic drive can be pushed and/or supported by the piston of the electric drive.
  • the piston of the electric drive can be moved in the pressure chamber.
  • the device further has a control device that is configured to operate the throttle valve in different operating modes.
  • the operating modes can preferably have a purely pneumatic drive operating mode in which only the pneumatic drive is operated to move the valve member and/or to hold a position of the valve member, preferably to close the throttle valve (e.g. to assume the closed position or the partially open position) .
  • the operating modes can preferably have a purely electric drive operating mode in which only the electric drive is operated to move the valve member and/or to maintain a position of the valve member, preferably for fine-tuning the flow cross section.
  • the operating modes can preferably have a combination operating mode in which both the pneumatic drive and the electric drive are operated to move the valve member and/or to maintain a position of the valve member, preferably simultaneously.
  • a control pressure of the pneumatic drive can be adjustable for the combination operating mode.
  • the control pressure is usually 5-6 bar.
  • the control pressure can be adjustable, for example, from 0 bar to max.
  • control device can refer to electronics (e.g. designed as a driver circuit or with microprocessor(s) and data memory) and/or a mechanical, pneumatic and/or hydraulic control, which, depending on training, can take on control tasks and/or regulation tasks and/or processing tasks. Even if the term “control” is used here, it can also expediently include or mean “rules” or “control with feedback” and/or “processing”.
  • the valve member has a passage channel, preferably a notch, for allowing a (e.g. pulp-containing, fiber-containing or piece-containing, liquid) filling material to pass through (e.g. at low flow speed), preferably in a partially open position of the throttle valve, in which the throttle valve can essentially only be passed through the passage channel.
  • the passage channel can have the advantage that small pulps, fibers, etc. have a larger cross section available at low flow velocities, thus reducing the risk of blocking.
  • valve member is screwed onto a piston of the pneumatic drive.
  • the throttle valve has a return spring which biases the valve member towards an open position or a closed position and which is preferably arranged coaxially with a piston of the pneumatic drive.
  • the throttle valve can have a bellows for sealing between the valve member and a valve housing of the throttle valve, which is preferably arranged coaxially to a piston of the pneumatic drive.
  • the throttle valve is designed as an angle seat valve.
  • the angle seat valve can advantageously be a comparatively low-flow-resistance straight-through valve with a comparatively low deflection of a filling material flow.
  • the angle seat valve can offer a good compromise between the requirements for flow characteristics, valve tightness and the required installation space.
  • the device further comprises a static throttle which is arranged upstream of the throttle valve and/or a flow measuring device which is arranged upstream of the filling valve and upstream or downstream of the throttle valve.
  • the static throttle can provide a flow cross section required for filling pulp-containing/piece-free/fiber-containing filling goods.
  • the one from the static choke can be designed to be comparatively large and thus allow higher flow speeds for non-critical (pulp-free/piece-free/fiber-free) filling goods.
  • a flow of the filling material can advantageously be measured using the flow measuring device.
  • a control device can operate the throttle valve and/or the filling valve (for example opening and/or closing) and/or adjust an operation of the throttle valve and/or the filling valve (for example opening duration and/or opening width).
