Definitions

  • the present invention relates to a device and a method for treating containers.
  • handling machines for containers are predominantly constructed as rotary machines.
  • This structure has several advantages. So are z. B. high machine performance possible with rotary machines.
  • rotary machines also have some disadvantages. On the one hand, they have large moving masses. Another disadvantage is that the treatment stations are located on the rotating part of the rotary machines. Both the treatment stations themselves and the process media (eg filling medium in filling machines, ink in printing machines, etc.) are therefore exposed to high centrifugal forces. In addition, an elaborate rotary feedthrough is required for the energy and media supply. In addition, rotary machines are relatively inflexible. It is difficult to expand the system. The entire system also has to be at a standstill if only a single treatment station is to be serviced.
  • process media eg filling medium in filling machines, ink in printing machines, etc.
  • the invention is therefore based on the object of providing a device and a method that do not have these disadvantages mentioned.
  • a device according to the invention for treating containers has at least one transport device for transporting the containers.
  • the device according to the invention has a handling device for transferring a predefined number of containers from the transport device in a transfer area and for delivering these containers to the transport device or another transport device in a transfer area.
  • the device according to the invention also has at least one other handling device for transferring a predefined number of containers from the transport device in a further transfer area and for delivering these containers to the transport device or another transport device in a wider delivery area.
  • the handling devices each have a movable carrier with which the removed containers can be moved on a transport path.
  • the handling devices are each assigned at least one treatment station.
  • the transport speed of the handling devices can be controlled in such a way that the transport speed of the handling devices during the transfer and / or delivery of the containers can be synchronized with the transport speed of the transport device and / or the further transport device. According to the invention, the transport speed of the handling device can be reduced after the transfer of the loading.
  • transport speed is to be understood as the speed at which the containers are moved along a transport path.
  • the transport speed can be reduced to zero.
  • the speed of the containers in the area of the treatment stations can preferably be reduced until the containers come to a standstill.
  • the movable carrier is advantageously a rotatable carrier. However, it can also be a pivotable carrier, for example. All handling devices advantageously have the same direction of rotation.
  • a handling device preferably has at least one handling unit for receiving a container.
  • a handling device particularly preferably has several handling units, each of which is suitable for receiving a container.
  • In the handling Exercise units can preferably be holding devices or the like that accommodate the containers. These are preferably grippers, such as, for example, neck handling clamps, which grip the containers.
  • the handling devices could e.g. B. instead of the rotary (lifting) mechanism also have a portal system, a tripod robot or a robot arm to nising and delivery to the continuously running transport device réellesynchro nise the containers and then to the treatment stations bring.
  • the containers are transported by the transport device along a feed path.
  • the transfer areas to the handling devices are preferably located along this inlet section.
  • Each handling device is advantageously assigned its own transfer area.
  • the number of transfer areas is preferably identical to the number of handling devices.
  • the device advantageously has a large number of handling devices. There are preferably several transfer areas along the feed path of the transport device.
  • one or more containers are thus transferred to a handling device, while the other containers are transported onward by the transport device.
  • the transported containers are advantageously transferred to a further handling device.
  • the transfer area is advantageously an exactly defined spatial area. This means in particular that each container that is transferred to a specific handling device is transferred within this transfer area. Before geous, the transfer area is smaller than 10 cm, preferably smaller than 5 cm and particularly preferably smaller than 1 cm.
  • each handling device removes one or more containers from the inlet in its transfer area.
  • the handling device preferably removes the containers with a rotational movement. If several containers are transferred to the handling device, these containers are preferably transferred one after the other in the transfer area, that is to say essentially at the same transfer point.
  • the containers are removed from the inlet using a removal device, for example a robot, and transferred to the treatment stations. In this embodiment, the containers are not transferred at the same transfer point.
  • the delivery area is advantageously an exactly defined spatial area. This means in particular that each container that is dispensed by a specific handling device is dispensed within this dispensing area.
  • the delivery area is advantageously smaller than 10 cm, preferably smaller than 5 cm and particularly preferably smaller than 1 cm.
  • each handling device delivers one or more containers to the outlet in its delivery area.
  • the handling device preferably delivers the containers with a rotational movement. If the handling device dispenses several containers, these containers are preferably dispensed one after the other in the dispensing area, that is to say essentially at the same dispensing point.
  • a dispensing device for example a robot, and transfers them to the outlet. In this embodiment, the containers are not transferred at the same transfer point.
  • Each handling device advantageously has at least the number of treatment stations that corresponds to the predefined number of containers that are transferred to the handling device in a cycle at the transfer point.
  • the handling device preferably has exactly this number of treatment stations. If, for example, four containers are transferred to the handling device in one cycle, this handling device preferably also has at least four treatment stations.
  • the invention described here is therefore based on the object of providing a device and a method which, on the one hand, enable a high degree of variability in the filling of containers and, on the other hand, also high machine performance and which possibly also avoids the disadvantages that arise in rotary machines.
  • a device according to the invention for treating containers has at least one transport device for transporting the containers and a handling device Direction for the transfer of containers from the transport device in a transfer area and for the delivery of these containers (in particular after a treatment) to the transport device in a delivery area.
  • the device has at least one further handling device for transferring containers from the transport device to a further transfer area and for delivering these containers to the transport device in a further delivery area, the handling devices each having at least one movable carrier with which the removed containers can be moved on a transport path and wherein the handling devices are each assigned at least one treatment station.
  • the treatment stations are filling devices which at least partially fill the containers with a filling level, and these filling devices are arranged essentially stationary with respect to the transport paths.
  • At least partial filling is understood to mean that the containers are not completely filled, but are filled up to a certain level, that is to say partially filled. It is possible, for example, that the containers are first filled with a first component up to a certain level, then with a further component and, if necessary, with additional further components.
  • Essentially stationary is understood to mean that the filling devices are either arranged in a completely stationary manner, that is to say they do not move along the transport path of the containers, or the filling devices only move in a certain limited area. It would thus be possible for the filling device to be carried along with the containers over a predetermined part of the transport path in order to be able to fill them more quickly. For example, it would be possible for the filling devices to be carried along over an angle of, for example, a maximum of 10 ° or a maximum of 20 °. However, the filling devices are preferably arranged in a stationary manner.
  • the two handling devices or filling devices are arranged in series and the containers can be transported from the first to the second handling device and are thus preferably treated and filled in succession. It is thus possible that the containers are first filled by the first filling device, then transported to the second handling device and filled there by a second filling device. A sequence of the containers to be filled is preferably retained.
  • the transport speed of the handling devices can be controlled in such a way that the transport speed of the handling device can be synchronized with the transport speed of the transport device during transfer and delivery of the containers, and the transport speed of the handling device can be reduced and preferably even reduced after the containers have been transferred can be set to 0.
  • the transport of the containers can preferably be stopped and the containers are treated in a non-moving state and in particular are (partially) filled here.
  • the procedure described here achieves a relatively high output rate per hour, although larger or smaller outputs are also possible and, in addition, the device has the ability to fill each container differently.
  • the containers are therefore advantageously at least partially filled with different media compositions. It is possible, for example, to set a different degree of carbonation for the containers.
  • These satellites preferably rotate in order to pick up and dispense containers.
  • the rotation can then stop so that the containers to be treated are located under a treatment element, that is to say here a filling valve.
  • a treatment element that is to say here a filling valve.
  • a transfer system which can be, for example, a transport chain, a carousel or a long stator linear motor (LLM).
  • the handling device can for example have a transport means such as a transfer arm that rotates in a predetermined direction of rotation (for example clockwise or counterclockwise).
  • a transfer arm which preferably also has a gripping element for gripping the containers, one or more containers are gripped by a transfer system, that is to say the transport device, and transferred to the Flandhabungsvor direction.
  • the container is placed under a filling valve, the medium of which is to be filled into this special container.
  • the element sets such as the transfer arm continues its rotation and puts the filled containers back into the transport device, for example in an empty position of the transport device.
  • This can be, for example, an empty neck handling clamp on a carousel or in a long-stator linear motor that does not yet have a container.
  • containers with the transport device could be transferred to a large number of satellites, these satellites preferably being arranged on the outer circumference of the transport device.
  • the cycle can then start again.
  • handling devices or satellites are required in most cases.
  • a predetermined number (as shown below, for example 27) handling devices or satellites can be placed on a transfer carousel. The containers to be filled run through this carousel.
  • Each container is removed from the transfer circuit by a handling device, filled and then put back into the transfer circuit.
  • the advantage of this arrangement is that with the same dwell time of the containers in the handling device or the satellites, the sequence of the containers on the transfer carousel at the outlet is the same as the sequence at the inlet. This means that the container order of all containers is again the same as before the filling. This is particularly helpful for the downstream machine, because all containers that belong together, for example all containers of a customer order (for example four pieces) run out of the filling machine one after the other and can simply be packed in a cardboard box.
  • transfer units including the handling devices or satellites arranged therein can be placed one behind the other in order to increase the machine performance.
  • Modified transport paths for the containers can also be provided, depending on the desired product, for example. It would also be possible to combine handling devices with rotary machines. Transfer stars and carousels preferably rotate at a constant speed and the corresponding treatment stars or handling devices work in a clocked manner.
  • a substantially or completely stationary position of the filling valves can be achieved by the invention. For this reason, no rotary feedthrough is required for a media supply.
  • the stationary arrangement of the filling valves also makes it possible to clean or maintain individual valves during production. These are simply not equipped with containers for the time of their maintenance.
  • the first filling device is suitable and intended to fill the containers with a first liquid and the second filling device is suitable and intended to fill the containers with a second liquid that differs from the first liquid .
  • a distinguishing feature here can be, for example, whether the liquid is a carbonated and a non-carbonated drink, such as water, for example.
  • a first liquid can also be a syrup, for example, and the second liquid can be a flavoring substance.
  • the first and the second liquid can also differ in terms of their filling quantity.
  • the first liquid and the second liquid are preferably also filled in different amounts.

  • the transport device preferably subsequently conveys the containers to both filling devices.
  • At least one handling device has several treatment stations in the form of filling devices.
  • several filling valves can be provided on a handling device.
  • This filling valves can fill the same type of liquid or different liquids.

  • At least one flap handling device has at least two movable folding elements for folding the containers, these folding elements being movable independently of one another.
  • the containers can move along a predetermined transport path. This makes it possible for a handling device to transport a container in a targeted manner under a specific filling valve.
  • movable shuttles could also be provided, which are movable with respect to a long stator.
  • a first container could be gripped from the first folding element and moved into a first filling valve and a second container from the second handling element or the folding device under a second filling valve.

  • the advantage of a stationary arrangement of treatment stations for a stretch blow molding process is that the heavy blow molding station with its many media supplies no longer has to sit on a rotating blow wheel, but can simply be placed stationary in the machine. This brings a considerable cost advantage.
  • treatment stations for a decoration process it can be, for. B. be stations for labeling and / or printing.

  • the device preferably also has at least one vacuum pump.
  • the treatment station is arranged downstream of the transfer area and / or upstream of the delivery area in relation to the transport path of the containers. This arrangement preferably applies to each of the treatment stations.

  • the transfer area and the delivery area of a handling device are arranged spatially separated from one another.
  • the delivery area is preferably arranged after a 180 ° rotation of the handling device starting from the transfer area.
