Definitions

  • the present invention relates to a displacement device for at least one handling device, in particular for a gripper device of a packaging machine, comprising at least a hinge mechanism on which the handling device is received.
  • the handling device can be displaced between at least one first position and at least one second position by means of the joint mechanism.
  • the present invention also relates to a method for relocating a handling device with such a device
  • Displacement device and a packing machine with such a displacement device.
  • components and in particular tools or other processing and / or handling modules are moved back and forth between different positions in order to carry out processing and / or to convey objects or products from one position to another.
  • an empty sack is gripped from a supply by a gripper device and attached to a filler neck, depending on the configuration.
  • the filled sack can then from the gripper device z. B. be conveyed to a locking station or the like.
  • a disadvantage of such systems is that, due to the polygon effect, a lifting movement of the joint mechanism also acts on the sack, as a result of which the shape or the volume of the sack changes at least temporarily. Raising and lowering the head area can cause air turbulence. This can lead to undesired leakage of product.
  • the displacement device according to the invention for at least one handling device comprises at least one articulation mechanism on which the handling device is received.
  • the handling device is in between by means of the hinge mechanism at least one first position and at least one second position displaceable.

  • the hinge mechanism or four-bar arrangement is designed in particular in the manner of a coupling mechanism, so that a particularly reliable, stable and specific shift from the first position to the second position and back can take place.
  • the displacement device according to the invention offers many advantages. A significant advantage is that due to the special design of the hinge mechanism or the special design of the link and the coupling to each other, a substantially rectilinear displacement of the handling device and thus, in the example of a gripper device, also an essentially rectilinear movement of a filled sack attached to the gripper device is made possible.
  • the handling device can preferably tilt slightly during the displacement, which does not, however, result in a change in the stroke or in the change in the vertical one Alignment leads so that no lifting movement is triggered. It is particularly preferred that at least one point of the coupling is displaced in a straight line or linearly. Around this point, usually the central axis of the handling device or the gripper device, the rest can then tilt slightly depending on the configuration, depending on the position.
  • the first link and the second link are preferably of different lengths.
  • the first link is shorter than the second link.

  • the receiving section for receiving the handling device is preferably arranged on the second section of the coupling.
  • the arrangement of the handling device on this section ensures a particularly straight-line displacement of the handling device.
  • the arrangement of the second articulation point of the first link on the first section and the second articulation point of the second link on the second section of the coupling are coordinated with one another.
  • the design of the coupling, the dimensioning of the handlebars and the attachment of the handlebars are coordinated with one another.
  • At least one actuator device is preferably provided. By means of such an actuator device, the joint mechanism and thus the handling device can be conveyed from the first position to the second position and back.
