Definitions
- the invention relates to a container treatment line, a control unit for a container treatment line, a cleaning machine and a method for operating a container treatment line.
- the invention also relates to a computer program for a control unit.
- Container treatment lines with a cleaning machine for cleaning Bephol tern and a container treatment plant downstream of the cleaning machine, which includes one or more container treatment machines, are well known from the prior art. Often such container handling lines are suitable for handling containers of different container formats, e.g.
- the container throughput of the container treatment system located downstream of the cleaning machine or at least one of its container treatment machines can be different for different container formats. It can be the case, for example, that the container treatment system or at least one of its container treatment machines can process or treat containers of a large container format more slowly than containers of a small container format, so that the container treatment system or the at least one container treatment machine during the treatment of containers one large container format can achieve a lower container throughput than with containers of a large container format. This means that when the container format of the container to be treated is changed, the container throughput of the container treatment system or of the at least one container treatment machine can change.
- the container throughput of the container treatment system or at least one of its container treatment machines can change regardless of a possible change in the container format, for example as a result of a fect and / or a technical malfunction of the container treatment system or individual container treatment machines or individual machine components.
- the cleaning machine is normally designed in accordance with the maximum container throughput of the downstream container treatment system. If the container treatment system is operated with its maximum container throughput, the containers are treated in the cleaning machine, such as immersing the containers in a lye or acid bath, with a desired treatment duration. If, on the other hand, the container treatment system is not operated with its maximum container throughput, but with a reduced container throughput, the transport speed of the cleaning machine is reduced, which means that the throughput time of the containers through the cleaning machine and thus also the treatment time of the containers, in particular one immersion time of the container in a lye or acid bath increases. This can lead to damage to the containers, e.g. if the temperature is too long and / or the alkali and / or acid is too long. Reusable PET bottles are particularly affected by this, but damage, such as increased glass corrosion, can also occur with glass bottles in such a case.
- the invention is based on the object of creating a way of avoiding or at least reducing damage to containers during their transport through a cleaning machine.
- the container treatment line according to the invention comprises a cleaning machine for cleaning containers and a container treatment system downstream of the cleaning machine, which has at least one container treatment machine. Furthermore, the container treatment line according to the invention comprises a conveying device for conveying the containers to the cleaning machine, for example in jostling transport.

- Said transport device has a plurality of carrier units arranged one behind the other in the transport direction of the transport device, each with a plurality of container receptacles arranged transversely to the transport direction for folding the containers during their transport from the container inlet to the container outlet.
- the cleaning machine comprises a loading device for loading at least some of the container receptacles with the containers.
- the container handling line includes a control unit.
- the container treatment line according to the invention is characterized in that the control unit is set up to process data relating to the container throughput of the container system and / or to the container throughput of the at least one container treatment machine and to control the loading device in such a way that one of the carrier units and / or one Majority of the carrier units depending on the container throughput of the loading container treatment system and / or the container throughput of the at least one container treatment machine is either charged with containers by means of the charging device or left empty.
- the control unit can control the loading device in such a way that depending on the container throughput of the container treatment system and / or on the container throughput of the at least one container treatment machine - all carrier units of the transport device are loaded with containers or
- the container treatment system and / or the at least one container treatment machine is operated with a first, low container throughput, for example some of the carrier units can be left empty and some of the carrier units can be loaded with containers. If, on the other hand, the container treatment system and / or the at least one container treatment machine is operated with a second, higher container throughput, more carrier units, in particular all carrier units, can be loaded with containers.
- the loading of the carrier units which is dependent on the container throughput, means that there is no need to change the transport speed of the cleaning machine to a considerable extent in order to adapt the container throughput of the cleaning machine to the container throughput of the container treatment system and / or the at least one container treatment machine.
- a substantially constant throughput time of the containers through the cleaning machine or through its processing stations can be achieved (largely) independently of the container throughput of the container treatment system and / or the at least one container treatment machine.
- too long a treatment time for the containers in the cleaning machine in particular too long a time for the containers to be immersed in an acid or alkali bath of the cleaning machine, can be avoided.
- damage to containers during their transport through the cleaning machine which can be attributed to an excessively long treatment time of the containers in the cleaning machine, can be avoided or at least reduced.

- This sequence of carrier units 8 loaded on the one hand and carrier units 8 left empty on the other hand is purely exemplary. In principle, a different sequence of loaded and empty carrier units 8 and / or a different ratio of loaded to empty carrier units 8 is also possible.
- the following description of further exemplary embodiments is limited primarily to the differences from the exemplary embodiment from FIGS. 1 to 3, to which reference is made with regard to features and functions that remain the same. Identical and / or corresponding elements are designated with the same reference symbols where appropriate.
- Features of the exemplary embodiment from FIGS. 1 to 3 not mentioned below have been adopted in the further exemplary embodiments without being described again.
- Fig. 4 shows a schematic, greatly simplified representation of a second Benzol ter alliancesline 1b in a view from above.
- the second container treatment line 1b differs from the first container treatment line 1a from FIGS. 1 to 3 essentially in that, in the second container treatment line 1b, the cleaning machine 2 has a locking element 16 in each of several of its lanes 10 for blocking and releasing the associated lane 10.
- the cleaning machine 2 comprises a drive device, not shown in the figures, for driving the locking elements 16.
- this drive device is controlled by the STEU tician 14, which also controls the loading device 12 of the cleaning machine 2.
- the drive device for driving the locking elements 16 is controlled by the control unit 14 in such a way that the associated lanes 10 are either locked or released depending on the container throughput of the container treatment machine 22 by means of the locking elements 16.
- FIG. 4 In order to illustrate the functioning of the blocking elements 16, several containers 17 located on or in front of the container inlet 4 are shown in FIG. 4, which are fed to the cleaning machine 2 by means of the inlet-side conveyor 23 in jostling transport. If one of the lanes 10 is blocked by means of the associated blocking element 16, no containers 17 can reach the loading device 12 via this lane 10, so that the containers 17 are aligned with this lane 10 arranged container receptacles 9 of the carrier units 8 from the loading device 12 are not loaded with containers 17.
- Fig. 4 follow three immediately one after the other on ordered carrier units 8 loaded with containers, each one left empty carrier unit 8.
- the loaded with containers carrier units 8 only those container receptacles 9 are loaded with containers that are not aligned to a means a blocking element 16 blocked lane 10 are arranged.
- Fig. 5 shows a schematic, greatly simplified representation of a third Benzol ter alliancesline 1c in a view from above.
- the cleaning machine 2 comprises a spray device 18 with a plurality of spray nozzles 19 for spraying the containers with a cleaning medium, such as water.
- a cleaning medium such as water.
- three spray nozzles 19 are shown as an example.
- Each of these spray nozzles 19 shown is representative of a spray nozzle of a cross row of nozzles consisting of several spray nozzles arranged one behind the other transversely to the transport direction 7 for spraying several containers.
- the number of spray nozzles in the respective transverse row of nozzles is advantageously equal to the number of container receptacles 9 that each carrier unit 8 has.
- the spray device 18 has several shut-off and / or throttle elements 20, which are designed, for example, as valves, for influencing the cleaning medium flow through the spray nozzles 19 or the cross rows of nozzles, each of the shut-off and / or throttle elements 20 one nozzle transverse row is assigned in each case.
- the shut-off and / or throttle elements 20 are arranged in supply lines of the spray device 18, via which the spray nozzles 19 are supplied with the cleaning medium.
- Said shut-off and / or throttle elements 20 are connected to the control unit 14 via control lines (not shown in the figures) and are controlled by it.
- Each of the shut-off and / or throttle elements 20 is controlled by the control unit 14 in such a way that the respective shut-off and / or throttle element 20 is shut off or throttled when, after a carrier unit 8 loaded with containers, an empty carrier unit 8 or a group of several Immediately one behind the other, left empty carrier units 8 which happen to the respective blocking and / or throttle member 20 assigned to the cross-row of nozzles. In this way it is achieved that carrier units 8 which have been left empty are not sprayed with the cleaning medium or are sprayed with a smaller amount of cleaning medium than the carrier units 8 loaded with containers.
- Fig. 5 is an example of the middle of the three shown shut-off and / or throttle members 20 shut off or throttled, since in the snapshot of FIG Throttle member 20 associated spray nozzle 19 or nozzle cross row happened.
- Fig. 6 shows a schematic, greatly simplified representation of a fourth Benzol ter alliancesline 1d in a view from above.
- the cleaning machine 2 comprises a spray device 18 with several spray nozzles for spraying the container with a cleaning medium.
- a spray device 18 with several spray nozzles for spraying the container with a cleaning medium.
- three spray nozzles 19 are exemplarily provided, each of these spray nozzles 19 is representative of a spray nozzle of a cross row of nozzles consisting of several transverse to the transport direction 7 one behind the other spray nozzles for spraying several containers.
- the spray device 18 comprises several pumps 21 for conveying the cleaning medium to the spray nozzles 19, each of the pumps 21 being assigned one of the cross rows of nozzles.
- the pumps 21 are connected to the control unit 14 via control lines (not shown in the figures) and are controlled by it.
- Each of the pumps 21 is controlled by the control unit 14 in such a way that the delivery capacity of the respective pump 21 is reduced if, after a carrier unit 8 loaded with containers, an empty carrier unit 8 or a group of several empty carrier units 8 arranged immediately one behind the other the transverse row of nozzles assigned to the respective pump 21 passes. In this way it is achieved that carrier units 8 which have been left empty are not sprayed with the cleaning medium or are sprayed with a smaller amount of cleaning medium than the carrier units 8 loaded with containers.
- one or more sensor units can be used to monitor whether a carrier unit 8 or a group of several carrier units 8 arranged directly one behind the other is loaded with containers or left empty .
- the control unit 14 controls the valves 20 or the pumps 21 of the spray device 18 as a function of the sensor signal (s) from the sensor unit (s).
- the loading status of a carrier unit 8 or a group of several carrier units 8 arranged directly one behind the other is determined purely by software, ie without the use of a sensor unit.
- the loading status of a carrier unit 8 or a group of carrier units 8 can be based on information about how the loading device 12 was activated by the control unit 14 when the carrier unit 8 or the group of carrier units 8 passed the loading device 12 , be determined.
