DETAILED DESCRIPTION

(4) FIG. 1 shows schematic representation of a container treatment system 100 according to one embodiment. The container treatment system in this embodiment comprises a clean room 120 in which a container treatment machine 101 is arranged. This container treatment machine can be any machine commonly employed in the beverage processing industry. In particular fillers that fill a product into a container can be considered. Similarly, preferably mold filling machines can be considered, in which the product is likewise introduced into the preforms for molding the preforms to the finished container. In principle, any container treatment machine treating a container or preforms with an interior space open to the environment can be arranged in clean room 120.

(5) In the embodiment presently shown, the container treatment machine comprises a carousel 111 on which several container treatment stations 112 are arranged.

(6) The embodiment shown there is of course not mandatory.

(7) Even if presently not shown, it is provided that the container treatment machine has some kind of communication through the wall of clean room 120 via which containers from outside clean room 120 can be supplied to container treatment machine 101 without impairing the controlled atmosphere within clean room 120. For example, a lock, presently not shown, can be provided through which containers can be guided continuously or cyclically into the clean room and supplied via suitable transport devices to container treatment machine 101.

(8) According to the invention, a robot 102 is further arranged in clean room 120. This robot is configured to exchange one component, for example component 140, of container treatment machine 101 for a further component.

(9) For this purpose, a magazine 130, in which or on which one or more further exchangeable components 131 are stored, is provided in this embodiment. In the embodiment shown in FIG. 1, robot 102 can therefore remove component 140 from container treatment machine 101 and deliver it to magazine 130. Furthermore, the robot can remove one of exchangeable components 131 stored in magazine 130 from the magazine and supply it to container treatment machine 101.

(10) The exchangeable components can be a wide variety of components, in particular relatively small components. These include blow molds and sealing elements or sealing devices. Further includes are bracket segments or slides and spike elements. Other relatively small and lightweight components as well can be exchanged by the robot, depending on the demand and configuration of the container treatment machine. Robot 102 can be configured, in particular, to transport and exchange components (i.e. attach or remove them from container treatment machine 101) having external dimensions of up to 50?50?50 cm and a weight of up to 30 kg.

(11) In the embodiment presently illustrated, robot 102 comprises a robotic arm 103 which can be attached, for example, to a support 105 of the robot. Robotic arm 103 can comprise several joints 132 and 133 and several segments 134 and 135, each connected to at least one of the joints. The joints can be rotatable, pivotable, or movable in any other way, so that different segments 134 and 135 can be moved relative to each other.

(12) Robotic arm 103 is preferably connected via a joint to support 105. Support 105 can either be fixedly mounted in clean room 120 or be mounted movable along a guide 104. Guide 104 can be a stator, so that guide 104 and support 105 together form a linear drive. This has the advantage that lubricants can be avoided to the degree possible and contamination of clean room 120 can then be prevented. The attachment of the robotic arm by way of support 105 to guide 104 also allows for an increase in the range of motion of robot 102. While the robotic arm in the embodiment presently shown is illustrated as being movable along a guide arranged at the ceiling of clean room 120, this is not mandatory. Guide 104 can be arranged, for example, on one of the side walls or on the ground of clean room 120. The latter variant offers the advantage that any leaking lubricants or similar substances can be extracted directly, for example, in designated openings or containers on the ground, thereby reducing the risk of contamination of containers treated in the container handling machine.

(13) Also the embodiment of guide 104 as a substantially straight element is not mandatory. The guide can have, for example, a curvature or extend, for example, snaking along the ceiling of clean room 120, so that an area of clean room 120 as large as possible can be covered by robot 102.

(14) If, for example, the container treatment machine is configured as a rotary machine, as presently shown, it can be provided that the guide is configured such that robot 102 can reach any place at the perimeter of the container treatment machine or at the perimeter of carousel 111.

(15) Alternatively or in addition, it can also be provided that the carousel of the container treatment machine can be moved in a clocked manner so that one or more components to be exchanged are by successive rotation of the carousel successively moved to a position in which robot 102 can reach and exchange them. The guide in this embodiment does not have to lead around the entire container treatment machine, but can also be formed only around a part or along a part of the perimeter, or robot 102 can be firmly arranged in the clean room, for example, by way of support 105.

(16) For the embodiment presently shown, but also for all other embodiments described below, robot 102 can act either autonomously or at least partially autonomously or be controlled by an operator, preferably from outside the clean room. In the first example, robot 102 can be associated with a processor unit which is preferably configured as artificial intelligence and has a memory in which several motion profiles are stored which can be retrieved according to the requirement profile (component to be exchanged and related actions) and converted into a motion of the robot.

(17) If robot 102 is controlled by an operator, it is provided that a control terminal is arranged, preferably located outside clean room 120, so that the robot can be controlled without the need to open the clean room. The control terminal can be connected to robot 102 via a data line, preferably also a wireless connection, so that control signals can be exchanged.

(18) Similarly, robot 102 can have suitable sensors that allow determining the position of the robot relative to components or other objects within the clean room.

(19) It can furthermore be provided that the robot comprises suitable devices for self-cleaning (not shown). For example, if robot 102 (as described in FIG. 3) is equipped with a nozzle with which it can clean components of the container treatment machine, then the robot can further be configured in such a way that it can at least in part self-clean. Dedicated cleaning devices on the robot are presently also conceivable.

(20) FIG. 2 shows an embodiment alternative to the embodiment shown in FIG. 1 for supplying exchangeable components. In the embodiment presently shown, a lock 240 is arranged in the wall of clean room 120. This lock allows the interior of clean room 120 to be in communication with the outer environment of the clean room. This communication is preferably not permanently open, but the lock disposes of lockable entrances 242 and 243, which can be formed, for example, as doors. It can be provided that mechanical measures or control system measures are taken to prevent the doors from opening at the same time. This ensures that only door 243 or door 242 is open and that contamination of the interior of clean room 120 is prevented.

(21) Furthermore, it can be provided that a sterilization device is arranged in the lock and can sterilize an exchangeable component 132 introduced into the lock. Sterilization device 241 can be formed, for example, comprising one or more nozzles which can introduce a sterilization medium, preferably a liquid or gaseous medium, into the region of lock 240 while openings 242 and 243 are closed, in order to sterilize the atmosphere within lock 240 as well as component 132 introduced thereinto. For example, the action of a sterilizing medium, such as hydrogen peroxide, can take place. The introduction of peracetic acid in liquid form or as a mist is also conceivable.

(22) In any case, robot 102 is configured in such a way that it can first remove from the lock an exchangeable component 131 which has been introduced by an operator into lock 240, and can then supply or attach it to container treatment machine 101. The same applies, of course, to an exchangeable component attached to the container treatment machine 101 which is to be removed from the container treatment machine. In this case, robot 102 removes this exchangeable component from the container treatment machine and places it through opening 243 into lock 240, from where it can then be removed by an operator via opening 242. In such a case, the sterilization of the exchangeable component or the atmosphere prevailing in the lock after introduction of the exchangeable component by robot 102 into lock 240 can be dispensed with since the risk of contamination of the interior of clean room 120 is no longer given. Nevertheless, it can be partially desirable to sterilize the exchangeable component, which is possible according to the previously described method with the aid of the sterilization device.

(23) FIG. 3 shows a further embodiment, in particular of robot 102, as part of container treatment system 100.

(24) In the embodiment presently shown, the robot disposes in particular of a tool 354 with which it can interact with components to be exchanged, but also with other parts of the container treatment machine, in such a way that the disassembly and installation of an exchangeable component is possible. For example, this tool can be a gripper. The embodiment is also not restricted to a single tool, so that, for example, a kind of screwdriver can be provided to loosen screw connections and, furthermore, the gripper described can be provided to grip the exchangeable component and to remove it from or attach it to the container treatment machine.

(25) One or more tools can be driven by suitable drives. For example, one or more electric motors can be provided on or in robot 102 and be associated with a corresponding tool 354 and actuated to cause the latter's movement or interaction with other components of the container treatment machine. In particular, the electric motors can be servomotors with a high degree of response accuracy.

(26) Alternatively or in addition, one or more media passages 351 can be provided which are in communication, for example, on one side with an actuatable pump and on the other side establish a connection to tool 354. By having a medium act upon these lines (for example liquid or gas), pneumatic or hydraulic operation of tool 354 can take place.

(27) Alternatively or in addition to this embodiment, it can be provided that robot 102 comprises a nozzle 352 via which a medium 353, for example, a sterilizing medium such as hydrogen peroxide, or a sterilizing liquid, such as peracetic acid, can be output to sterilize either one of the exchangeable components or a further component of the container treatment machine. In addition or alternatively, for example, a lubricant can be applied via a suitable nozzle and lubricate components or exchangeable components of the container treatment machine should this be necessary. This nozzle can also be advantageously used to enable autonomous cleaning of the robot. For this purpose, the robot can move the robotic arm in such a way that the nozzle is moved over one or more of the robot's components so that the medium can be applied to them by nozzle 352.
