Definitions

  • the invention relates to a transport star with a container clamp for detecting containers.
  • Container clamps are used for holding and transporting empty or filled containers, in particular bottles, in container treatment plants.
  • transport stars with container clamps have the advantage that the container is completely held by the container clamp and no further guide elements for positioning the container on the transport star are necessary.
  • a transport star with container clamp is known, for example, from EP 2 159 172 A1.
  • This has a rotatable base body and a plurality of gripping devices distributed over its circumference for gripping the containers, wherein each gripping device has pairwise corresponding, in particular to the base body radially arranged clamping arms.
  • the disclosed transport star has two levels of gripping means, which are arranged one above the other, in order to be able to grasp the bottles in the area of the bottle belly and the neck of the bottle at the same time.
  • the control of the staple arms takes place via a cam arrangement, so that the staple arms can be moved back and forth between an opening position in which the container is guided between the staple arms and a gripping position in which the staple arms engage the containers.
  • the container treatment plant is used for different container sizes, it is necessary to adapt the gripping device to the container diameter.
  • an exchange of the gripping device eg. The entire transport star must be made.
  • the container is usually introduced from a circular path coming into the transport star. He must thus be passed by the clamp arms, between the clamp arms. Due to the limited opening width of the gripping arms only containers with slightly different diameters can be transported by a gripping device without replacing the gripping device.
  • a clamp arm which is radially adjustable to bridge a distance between the respective container transport devices.
  • the containers can be introduced as far as possible frontally between the clamp arms.
  • the gripping device is technically very complicated and thus on the one hand particularly prone to error and on the other to clean particularly expensive.
  • the invention is therefore an object of the invention to provide a star transport with a particularly simple constructed container bracket, which makes it possible to better exploit the opening width of the container bracket.
  • the transport star comprises a central rotating pocket and has a container clamp with two clamp arms which are designed to grip a container and pivotably mounted about an axis of rotation and a guide device which is designed and arranged in such a way that the container clamp in FIG radial direction between a starting position and a detection sungsposition is movable and with a second movement of the guide means, the clamping arms are pivotable about the axis of rotation.
  • the transport in a container treatment plant usually takes place from one transport device to the next.
  • a first transport device moves the container, for example, coming from a circular path to a transport star and positioned the container between two clip arms. Due to the inevitably intersecting transport orbits of the first transport device and the transport star, the container can only be transported between the clamp arms of the transport star, when the opening width of the clamp arms is significantly larger than the diameter of the container.
  • the inventive transport star it is possible, for example, to position containers coming from a circular path in the radial direction in front of the clamp arms, to move the clamp arms radially towards the container and to grasp the container.
  • the clip arms thus pass through two movement sections, on the one hand a radial movement to the container and on the other hand a pivoting movement about its axis of rotation for detecting the container.
  • the opening width of the bracket arms is only slightly larger than the container diameter. Due to this improved utilization of the opening width of the clamp arms, it is possible, for one thing, to use the inventive transport star to detect containers with a larger diameter or, alternatively, to position a higher number of container clamps on the transport star.
  • the container clamp Due to the guide means with which both the radial movement of the container clamp (the clamp arms) and the pivotal movement of the clamp arms is controlled, the container clamp is particularly compact despite a particularly simple construction and also has particularly few components, which, for example, the assembly, disassembly and cleanability are greatly simplified.
  • the first and second movement are to be understood in particular as two partial movements of an overall movement of the guide device.
  • Each partial movement can take place as forward or backward movement along a partial section of a movement path.
  • the first partial movement is thus forward (outward) or backward (inward) along a first portion of the trajectory while the second partial movement is also forward (outward) or reverse (inward) along a second portion of the trajectory.
  • Between the first section and the second section of the trajectory is a flowing transition.
  • the movement paths are arranged rectified.
  • the two movements can be carried out in succession, it being possible for the first movement or also the second movement to be carried out first, depending on the starting position of the container clamp.
  • the radial direction is understood to be the direction of a center axis passing through the clamp arms.
  • the container clamp is arranged such that the central axis of the container clamp is aligned radially to the axis of rotation of the transport star.
  • the radial direction can thus relate to the axis of rotation of the transport star.
  • a plurality of container brackets is arranged. Due to the radial displaceability and the associated NEN better exploitability of the opening width of the inventive transport star allows it to be arranged opposite known transport stars significantly more container clips on a transport star of the same size, since the opening width of the staple arms can be better utilized.
  • a transport star has a fixed number of bin grippers or staples at its periphery. Dividing the circumference by this number of container clamps, the maximum possible container diameter results from transportable containers.
  • this maximum possible container diameter can not be fully utilized in conventional gripping or stapling systems, because the containers would collide with these starting from a certain diameter when immersed between the gripping or clamping arms. Due to the radially inward pulling in of the respective gripping or clamping arms before and / or during the immersion of the containers, this collision is avoided so that larger containers can be transported in diameter than in the case of conventional transporting stars.
  • the container clamp is formed to have a gripping portion between which the container is clamped.

This becomes possible, as described above, because the gripper is pulled radially inwards and thus the necessary space for movement is provided to the incoming container.
  • a further advantage is that an automatic adaptation of the end position of the clamping arms to different container diameters takes place.
  • the aforementioned transport star is thus advantageously part of a larger transport system, in which containers are taken over by an adjacent likewise rotating transport and / or treatment device of the transport star described. Furthermore, usually downstream of another transport and / or treatment device connects to be forwarded to the container.
