  • Such a method is e.g. known from DE 10 2010 007 541 A1.
  • Preforms for the known methods consist of a thermoplastic, for example PET, PE or PP, and are usually produced by injection molding.
  • a preform can be formed into a container, it is thermally conditioned, that is, in particular heated and provided with a suitable temperature profile.
  • the body of the preform is e.g. heated to about 120 ° C and malleable, while the mouth area may only reach significantly lower temperatures, since the preform is held at the mouth area in the forming and filling machine and may not deform under the usual holding forces there.
  • a device for producing filled containers has a heating section along which
  • the preforms are moved on transport wheels through the machine having preform holders.
  • process wheels e.g. are combined with the forming and filling stations or the sealing stations of the machine, and on which the preform is formed and filled or sealed, or pure transport wheels on which the preform or the container is transported from one station to the next.
  • a device for filling and closing containers which comprises a first process wheel for filling a container and a second process wheel for closing a filled container and a transfer device for transferring the filled containers from the first process wheel to the second process wheel.

  • the apparatus may also advantageously comprise a heater for thermally conditioning the preforms. Further additional components of the device are conceivable without departing from the scope of this application.
  • the containers filled in the filling station are transported over a linear distance to the capping station.
  • no reversal of the direction of rotation takes place, as is the case with the machines used hitherto.
  • On the filled container act in the transition into the transfer device no opposing accelerations. There is no danger that contents could spill over, so that the device is contaminated and the previously filled volume of filling material is changed.
  • the linear transfer path of the transfer device is arranged tangentially to the circumference of the first process wheel and / or to the circumference of the second process wheel.
  • the takeover of the filled, unsealed container from the filling station into the transfer device and / or from the transfer device into the closing device can take place smoothly, in particular without a reversal of the direction of rotation and the associated acceleration.
  • the risk of spilled filling material is significantly reduced.
  • the first and the second process wheel and the transfer device can be arranged within a wet region which is closed off from the other components of the device.
  • a wet region which is closed off from the other components of the device.
  • foaming filling in the bottling of carbonated beverages or by faulty or bursting containers are advantageous to summarize the components for filling until closing the container in a so-called wet area, which is isolated by suitable measures, such as locks, for example by air curtain, etc., from the other components.
  • the transfer device can have a drying device with which filled containers, which have become wetted by spilled filling material, can be dried to close before being fed into the process wheel. The load of the components of the process wheel for closing and all other downstream components due to moisture can be effectively reduced.
  • the transfer device may advantageously have an inspection device, in particular to check the level of filled containers.
  • the transfer means may comprise holding means for the containers which are movable at variable speed along the transfer path.
  • the holding devices can be driven along the transfer path with a variable pitch screw drive and / or with a magnetic drive.
  • the distances between adjacent containers between the two process wheels can be changed and adapted to a different pitch of the process wheels.
  • the process wheel for sealing may have a smaller radius or be more closely equipped with processing stations than the process wheel for filling a container, particularly a combined forming / filling wheel in which the container is simultaneously formed and filled within a mold. The distances can then be adjusted along the transfer distance.
  • the space requirement of a machine can be optimized.
  • the filled containers are usually held by grippers in the region of the mouth. Along the transfer route, it may be advantageous to support and / or guide the filled containers at least partially in the region of their bottom.

  • It can this is a process wheel for filling empty containers or a process wheel for the simultaneous formation and filling of containers from preforms by introducing contents under high pressure into correspondingly conditioned preforms, wherein the preform is transformed into a filled container.
  • the device further comprises a second process wheel 2 for closing a filled container.
  • a transfer device 3 for transferring the filled containers from the first process wheel 1 to the second process wheel 2 is arranged.
  • the transfer device 3 has a linear transfer belt 4.
  • the transfer section 4 is tangential to the first process wheel 1, so that during the transfer no acceleration acts on the filled container, as is described, for example, in US Pat. in the transfer to a transfer wheel would be the case in which the filled container would be moved in an opposite circular path.
  • the connection of the transfer section 4 to the second process wheel 2 also takes place tangentially to the circumference of the second process wheel 2. There occurs an acceleration of the filled container through the transfer to the circular path of the process wheel 2. However, the acceleration is significantly lower than in the case of transfer from a counter-rotating transfer wheel.
  • the transfer section 4 is advantageously equipped with a drying device 5, for example a blower, in order to remove possibly spilled filling material from the outside of the filled containers and to carry on as little moisture as possible up to the second process wheel of the closing device.
