Definitions

  • the invention relates to a container transfer device for a container cleaning machine for moving containers, e.g. B. bottles made of glass or plastic, in container cells of the container cleaning machine.
  • containers e.g. B. bottles made of glass or plastic
  • the container cleaning machines comprise a multiplicity of cell carriers which extend along a longitudinal direction of the carrier and which in turn each receive a multiplicity of container cells which are arranged one behind the other in the longitudinal direction of the carrier. These container cells are intended to receive the containers and convey them through the container cleaning machine.
  • the containers in the container cells can be transported and cleaned intensively by the container cleaning machine, with the greatest possible protection.
  • an upright position means a position in which the container is supported by a container floor.
  • the corresponding container is now tilted by up to 90°.
  • tilting is not unproblematic, since each container is initially supported on a section of the container bottom on the driver and on the lateral surface on a corresponding guide surface.
  • an unstable area is traversed, since due to the initially substantially upright position of the container, the catches can cause the container to tilt in the opposite direction. This is particularly problematic when the container has an inwardly curved container base according to a design that is frequently provided nowadays.
  • the present invention is based on the object of specifying a container transfer device which, compared to the previously known container transfer devices, enables more reliable, trouble-free and more energy-efficient operation.
  • a tilting device with a support arm which is designed such that the containers in the feed position bear against the support arm via a lateral surface.
  • the feed position is a position of the containers which is intended to be provided when the tipping device is reached. Since the containers are generally fed in standing upright above the container floor, the containers in the feeding position are arranged with a container axis essentially vertical in the container transfer device, so that the weight is essentially supported by the container floor.
  • the containers In order to be able to insert the containers into the container cells, it is necessary for the containers to be transferred from the vertical to a substantially horizontally arranged end position, in which the weight of the containers is supported by a lateral surface enclosing the container base.
  • the invention teaches that the tilting of the containers and the movement into the container cell can be at least partially decoupled from one another, with the tilting angle between the vertical and horizontal position preferably being effected to a large extent and in a supported manner by the tilting device.
  • the unstable area within the tipping device can be passed through without causing the containers to be set up again.
  • the container lies against the support arm via the lateral surface. A supported and controlled transfer into the intermediate position is thus made possible by this support arm.
  • the angle for tilting into the feed position being between 0° and 40°, is preferably between 5° and 20°.
  • such an angle is too small to cause damage to the container.
  • the tilting device for the supported transfer of the containers from the feed position to the intermediate position can be pivoted over a pivoting angle of between 10° and 100°, preferably between 20° and 70° and particularly preferably between 30° and 60°.
  • the pivoting angle thus forms part of the total tilting angle required for the tilting.
  • a lifting guide is provided for moving the containers from the intermediate position into the container cells.
  • This lifting guide preferably has a guide surface, the guide surface being formed in such a way that the containers can be moved from the intermediate position into the container cells by an angle of less than 80°, preferably less than 50°, particularly preferably less than 40°.
  • a tilting of the container within the lifting guide therefore preferably also takes place.
  • the total pivoting angle is then made up of the angle for tilting into the feed position, the pivoting angle and the angle for transferring the containers from the intermediate position into the container cells.
  • the guide surface not to cause any further tilting of the container and for it to be designed accordingly as a flat and horizontally arranged surface.
  • a planar configuration has the problem that it is difficult to view the lifting guide from the outside. Damaged or incorrectly sorted containers can therefore not or only with difficulty be detected by the user. Access to the area where the bottle is inserted is also hardly possible.
  • the guide surface not only has a horizontal extent, but also a vertical extent that causes a vertical difference in height.
  • a configuration is also effected with the rotating drivers already known from the prior art.
  • the invention provides that the vertical extent is smaller than the horizontal extent, the ratio preferably being less than 1:2, particularly preferably less than 1:3.

  • the lifting guide has at least one, but preferably several drivers.
  • the drivers preferably extend through the guide surface and are designed to Abut movement of the container to the container bottom. Due to the flat position of the container when it is taken over by the carrier, only small forces occur here. The weight is mainly absorbed by the guide.
  • the drivers can be driven by various types of drive mechanisms.
  • the invention preferably provides an embodiment with a drive unit designed as a linear drive, which moves the drivers alternately back and forth along the guide surface, with the containers being moved into the container cells via the drivers during the forward movement and with the drivers in be moved back into a position during the backward movement in order to reach behind the following container.
  • a drive unit designed as a linear drive
  • Such an embodiment has basically been found to be effective, but the return journey represents a kind of dead time in which no containers can be transferred.
  • at least two carriers are preferably provided, which rotate below the guide surface, so that during the backward movement of a first carrier, a forward movement of a second carrier enables the movement of a container into a container cell.
  • Such a configuration can be made possible, for example, analogously to that from the prior art, via a rotating shaft with drivers that protrude essentially radially. Due to the flat design of the guide surface, however, a comparatively large radius is then necessary.
  • a so-called chain drive is therefore preferably provided as the drive unit.
  • This chain drive is formed from several chain links and is arranged along the guide surface. The chain allows the guide surface to be configured almost freely.
  • the drive unit preferably has a control unit which is designed as a cam control.

  • the subject matter of the invention is also a method according to claim 14 for moving containers from an intermediate position in container cells of the container cleaning machine with the container transfer device according to the invention, wherein the containers are transferred from a feed position to an intermediate position supported by a tilting device and the containers are then moved via a lifting guide into the container cells are moved.
  • the containers in the tilting device are first tilted from the feed position into the intermediate position and are then introduced into the container cells via the lifting guide.

  • the containers can be transferred to the container cells just by moving them.
  • the container cells are moved in an almost vertical direction ( ⁇ 10°) after the containers have been introduced.

  • the containers are accelerated during the movement along the guide surface. This means that the containers at the end or shortly before reaching the container cell have a higher speed than at the beginning, for example.
