Definitions

  • the present invention relates to a method and a device for closing a container with a screw cap, preferably for closing a beverage container in a beverage filling plant.
  • closure devices for example, mechanical systems are used in which the closure receptacle is connected to a drive via a magnetic coupling constant rotation speed is rotated. The rotation comes to a standstill when a limit torque in the magnetic coupling is exceeded.
  • servomotors for providing the rotation of the closure receptacle.
  • closure receptacle is also moved in its vertical position or height, for example in order to receive the closure, to move the closure onto the container, to follow a linear movement in the direction of the container while it is being unscrewed or to provide it, and to separate the closure receptacle from the closed container after the closure has been successfully applied.
  • a roller which is connected to the locking head having the locking receptacle, runs in a groove or guide channel.
  • devices for closing containers are known in which, instead of the mechanical lifting cam, the movements of the closure receptacle are generated by a linear motor.
  • a method for closing a container with a screw cap preferably for closing a beverage container in a beverage filling plant, comprising the steps of receiving a screw cap in a closure receptacle; moving the shutter receiver in a longitudinal direction to an initial height position; and rotating the closure receptacle in a predetermined direction of rotation at a first rotational speed.
  • the method is further characterized in that when a predetermined height position of the closure receptacle or a predetermined change in height of the closure receptacle is reached, the closure receptacle is rotated at a second rotational speed different from the first rotational speed.
  • the height position and / or the change in height is preferably determined relative to the initial height position.
  • the closure receptacle is preferably moved relative to the longitudinal direction of the closure receptacle.
  • the closure receptacle rotates at a second rotational speed different from the first rotational speed, it is possible to screw a screw cap at different speeds onto the one container mouth of a container to be closed.
  • the speed of rotation of the screwing-on movement of the screw cap can therefore be adapted over the course of the screwing-on process.
  • the method for closing can be adapted to different desired parameters, taking into account the respective materials used.
  • the second rotational speed is preferably lower than the first rotational speed.
  • the closure receptacle in a first section of the screwing on, can be rotated at a high rotational speed, so that the screw cap can be screwed quickly onto the container mouth in the first section of the screwing on.
  • the closure receptacle in a second section following the first section, can then be slowly unscrewed at the second rotational speed, which is preferably significantly lower than the first rotational speed, so that the unscrewing process can initially take place rapidly and then particularly precisely towards its end.
  • a comparatively high torque can be provided, which may be necessary to move the tamper-evident band of the screw cap over the tamper-evident band ring at the mouth.
  • the method can be designed in such a way that in the first section, before reaching the predetermined height position of the lock receptacle or the predetermined change in height of the lock receptacle, the torque with regard to the intended closing torque or opening torque is disregarded and is only considered in the second section.
  • the height position or the change in height is preferably predetermined in such a way that the seal is pressed into the mouth and / or the tamper-evident band has jumped over the tamper-evident band on the container in the first section before the predetermined height position or the given height change is reached.
  • This makes it possible to set the opening moment independently of the pressing in of the seal and / or the skipping of the tamper-evident band ring or the sliding of the tamper-evident band, and thus to be decoupled from one another.
  • undesirably high torques which are required for the aforementioned pressing in and / or skipping, and which are often above the desired closing torque or opening torque, can thereby be decoupled from the setting of the opening torque.
  • the screw cap is not screwed on as intended, but only up to one of the cases just mentioned, something up to the (incomplete) pressing in of the seal or up to the area in which the tamper-evident band is pushed against / over the tamper-evident band ring , the container is therefore only partially closed.
  • any combination of angular speeds or rotational speeds can be combined.
  • the closure receptacle is preferably rotated about an axis of rotation which is formed parallel to the longitudinal direction.
  • the initial height position preferably corresponds to a predetermined initial height position.
  • the initial height position can also be determined by detecting a force or force change in the longitudinal direction acting on the closure receptacle, the initial height position corresponding to a height position of the closure receptacle at which a predetermined force acts on the closure receptacle in the longitudinal direction.
  • the force or force change in the longitudinal direction occurs here, for example, as soon as the screw cap touches the container mouth. With a further movement of the closure receptacle in the longitudinal direction towards the container, the force in the longitudinal direction increases accordingly.
  • a linear motor for moving the closure receptacle in the longitudinal direction
  • the force in the longitudinal direction can be determined by detecting and converting a current supplied to the linear motor. After the container mouth comes into contact with the screw cap accommodated in the closure receptacle, the current increases, in particular due to the increase in the drag error of the linear motor, when the linear motor is given a speed in the longitudinal direction.
  • the predetermined change in height can preferably correspond to the change in the position of the closure receptacle in the longitudinal direction in relation to the initial height position. This can ensure that the screw cap is always reproducibly screwed on from the initial height position in the longitudinal direction by the same amount in the longitudinal direction for each container to be closed.
  • the predetermined height position is essentially constant.
  • the switchover always takes place at a predetermined switchover height and is independent of the height at which the closure touches the container. For example, any influence that may arise as a result of the fact that the height at which the closure touches the container can vary, depending on how the thread starts of the screw closure and mouth are referenced or oriented to one another.
  • the closure receptacle after the closure receptacle has been moved to the initial height position until the predetermined height position or the predetermined height change, or in other words after bringing into contact with the container mouth until the predetermined height position or the predetermined height change is reached, the closure receptacle is pressed with a first force in the longitudinal direction against the container mouth.
  • a counter-torque to the closing moment can in particular be generated in order to fix the container during the closing process.
  • a support ring of the container is preferably pressed into a plate with points in order to fix the container against rotation about the longitudinal direction.
  • the screwing of the screw cap onto the container mouth can also be supported, whereby by specifying the magnitude of the force as the first force, the screwing on is supported by a known parameter, for example the penetration of the closure seal into the mouth may be supported.
  • the closure receptacle is subjected to the first force in the longitudinal direction.
  • the rotation of the closure receptacle at the first rotational speed and the application of the closure receptacle with the first force take place essentially simultaneously, starting after reaching the initial height position until reaching the predetermined height position or the predetermined change in height.
  • the first force is preferably applied by means of the linear motor, a first current value being fed to the linear motor.
  • a first current value being fed to the linear motor.
  • the linear motor follows this movement and thereby maintains the specified current, preferably essentially constant.
  • the first force is preferably greater than the predetermined force which is optionally applied to the closure receptacle for determining the initial height position and / or for aligning the screw cap with respect to the container mouth or the thread of the container mouth.
  • one or more control parameters of the linear drive can optionally be set to zero or tared.
  • the closure receptacle is pressed in the longitudinal direction against the container mouth with a second force different from the first force.
  • the second force is preferably greater than the first force.
  • the closure receptacle is subjected to the second force in the longitudinal direction.
  • the rotation of the closure receptacle at the second rotational speed and the application of the closure receptacle with the second force take place essentially simultaneously, beginning with or after the predetermined height position or the predetermined height change has been reached.
  • the closure receptacle is rotated at the second rotational speed and / or the closure receptacle is pressed with the second force in the longitudinal direction against the container mouth until a torque that is set by the rotation of the screw closure on the container mouth reaches a predetermined torque value. It can thereby be achieved that the screw cap is screwed and tightened through the closure receptacle onto the container mouth with a torque of known height, the torque of known height essentially corresponding to the predetermined torque value.
  • the holding torque is preferably essentially constant over the entire predetermined period of time.
  • the second force is preferably also maintained over the predetermined period of time.
  • the closure receptacle can be moved from a transfer position to a pre-position in the longitudinal direction at a relatively high speed, preferably at a speed in a range of 1 m / s to 5 m / s, preferably 2 m / s.
  • the pre-position can be selected in such a way that the screw cap taken in the closure receptacle is at a predetermined distance from the container mouth, so that the screw cap does not come into contact with the container mouth.
  • the closure receptacle before the closure receptacle is rotated at the first speed, the closure receptacle is lowered onto the container mouth in the longitudinal direction until the closure receptacle is pressed against the container mouth with a predetermined initial force in the longitudinal direction.
  • the speed in the longitudinal direction is preferably selected to be comparatively low, preferably in the range from 0.01 m / s to 0.1 m / s, particularly preferably 0.02 m / s to 0.05 m / s, particularly preferably 0.03 m / s.
  • the movement of the closure receptacle and / or the force in the longitudinal direction against the container mouth are provided by a linear motor, the first force being generated by specifying a first value of a control current of the linear motor, and / or the second force is generated by specifying a second value of the control current / regulating current of the linear motor.
  • the rotational speed and / or the torque applied to the closure receptacle by a rotary motor the rotational speed and / or the torque being controlled / regulated by controlling / regulating a control current / regulating current of the rotary motor
