Description

[0001] The invention relates to a method for automatically calibrating a container treatment plant and a container treatment plant for carrying out the method according to the independent claims. State of the art

[0002] Because the machines in a container handling plant can be connected by one or more mass conveyors, the machines do not communicate with each other, their performance cannot be regulated, and almost every line has a different setup (conveyor length, performance, container formats, etc.), the effort required to calibrate a container handling plant at the customer's site is very high. The machines must be manually adjusted to an operating point and are then difficult to adjust without, for example, requiring further modifications to the container handling plant. Furthermore, pulsations must be avoided during mass transport. Achieving the perfect result (maximum performance without pulses in the system) requires a great deal of time and experience from the person adjusting the container handling plant. Task

[0003] The object of the invention is to provide a method for automatically calibrating a container treatment plant and a container treatment plant for carrying out the method, which can enable a higher-level line control of the container treatment plant for automatic commissioning. Solution

[0004] This object is achieved by the method for automatically calibrating a container treatment system and the container treatment system for implementing the method according to the independent claims. Further embodiments are disclosed in the subclaims.

[0005] The method according to the invention for automatically calibrating a container treatment plant, such as a filling plant, wherein the container treatment plant comprises a plurality of successive machines through which containers, such as plastic or glass bottles or cans, pass on a transport path, wherein each machine is assigned at least one sensor for detecting containers, comprises initially introducing containers into the container treatment plant and transporting the containers through the container treatment plant along the transport path, thereby recording sensor data from the sensors assigned to the machines and recording operating data of the machines.The method further comprises evaluating the sensor data and the operating data to create calibration data and creating the calibration data and using the calibration data for subsequent operation of the container treatment plant in an operating mode.

[0006] Sensor data can be recorded continuously or at regular intervals. For example, sensor data can be recorded until a given number of containers have initially been introduced into the container handling system, or until a given number of containers, containers, or pallets have left the container handling system.

[0007] The containers can be disposable or reusable.

[0008] A container treatment plant can be understood as the totality of the individual machines working together in an association.

[0009] If several consecutive machines are mentioned here, this should be understood to mean that these several consecutive machines can interact meaningfully.

[0010] The containers initially introduced can pass through the container handling system along a transport path. The transport path may vary slightly for each individual container or the bundles created from them, for example, with a first container buffer, a pasteurizer (which may include a pasteurization area and a buffer area, for example), and a second container buffer.

[0011] Containers can be transported on conveyor belts, container buffers (e.g., bulk conveyors), by neck handling, and / or by arrangement on turntables. Other transport methods are also conceivable.

[0012] The operating data of the machines can include, for example, depending on the type of machine, a transport speed, a temperature of the treatment medium.

[0013] Subsequent operation of the container treatment plant in an operating mode can be understood as operation of the container treatment plant after completion of the automatic calibration.

[0014] Recording sensor data may further include recording at least one point in time at which a condition is met at one of the machines. For example, the condition may include the arrival of a first container at the machine or a predetermined fill level of the machine with containers. For example, recording at least one point in time may occur for each of the sensors. For example, the at least one point in time may be specified in relation to a starting point in time at which the initial introduction of the containers into the container handling system began.

[0015] A fill level can indicate an empty, half-full or full state, or a percentage occupancy can be specified.

[0016] The recording of sensor data may further include detecting the number of containers initially introduced into the container processing system. For example, it may be determined that only after a certain number of containers (e.g., 1,000) have been initially introduced can containers arrive at a filling and closing device of the container processing system and a filling process begin.

[0017] The recording of sensor data may further comprise recording first sensor data from a first sensor of a first container buffer, for example for empty containers, wherein the first container buffer may be one of the plurality of machines of the container treatment plant, wherein the first sensor data indicate a full state of the first container buffer, or may comprise recording second sensor data from a second sensor of the first container buffer, wherein the second sensor data may indicate a half-full state of the first container buffer, or may comprise recording third sensor data from a third sensor of the first container buffer, wherein the third sensor data may indicate an empty state of the first container buffer.For example, a time may also be recorded at which the empty state or the half-full state or the full state of the first container buffer may be reached, for example in relation to a starting time at which the initial introduction of the containers into the container treatment plant began.

[0018] Alternatively or additionally, the time period that may have elapsed since the first container reached the first container buffer and until the first container buffer reached a full state can be stored.

[0019] For example, the first container buffer may comprise a mass conveyor.

[0020] The recording of sensor data may further comprise recording sensor data from a sensor of a filling and closing device, wherein the filling and closing device may be one of the plurality of machines of the container treatment plant, wherein the sensor data may indicate that a first container may have arrived at the filling and closing device. For example, a time at which the first container may have arrived at the filling and closing device may also be recorded, for example in relation to a start time at which the initial introduction of the containers into the container treatment plant began. For example, a number of initially introduced containers may also be recorded when the first container has arrived at the filling and closing device.

[0021] Recording sensor data may further comprise recording sensor data from a sensor of a pasteurizer, wherein the pasteurizer may be one of the multiple machines of the container treatment plant, wherein the sensor data may indicate that a first container may have arrived at the pasteurizer. For example, a time at which the first container may have arrived at the pasteurizer may also be recorded, for example, in relation to a starting time at which the initial introduction of the containers into the container treatment plant began. For example, a number of initially introduced containers may also be recorded when the first container has arrived at the pasteurizer.

[0022] Recording sensor data may further include recording the percentage occupancy of a buffer area, which may be encompassed by the pasteurizer. When the buffer area fill level has reached 100%, the time elapsed since the first container was initially introduced into the container handling system may also be stored. Alternatively or additionally, the time elapsed from the first container entering the buffer area until the buffer area fill level has reached 100% may be stored.

[0023] The recording of sensor data may further comprise recording first sensor data from a first sensor of a second container buffer, for example for full containers, wherein the second container buffer may be one of the plurality of machines of the container treatment plant, wherein the first sensor data may indicate a full state of the second container buffer, or may comprise recording second sensor data from a second sensor of the second container buffer, wherein the second sensor data may indicate a half-full state of the second container buffer, or may comprise recording third sensor data from a third sensor of the second container buffer, wherein the third sensor data may indicate an empty state of the second container buffer.For example, a first time point may also be recorded at which the empty state or the half-full state or the full state of the second container buffer may be reached, for example in relation to a starting time point at which the initial introduction of the containers into the container treatment plant began.

[0024] Alternatively or additionally, the time elapsed since the first pasteurized container reached the second container buffer and until the second container buffer reached the full state can be stored.

[0025] For example, the second container buffer may comprise a mass conveyor.

[0026] The recording of sensor data can further comprise recording sensor data from a sensor of a packer for creating bundles from a predetermined number of containers, wherein the packer can be one of the multiple machines of the container handling system, wherein the sensor data can indicate that the predetermined number of containers has arrived at the packer. For example, a time at which the predetermined number of containers may have arrived at the packer can also be recorded, for example in relation to a starting time at which the initial introduction of the containers into the container handling system began. For example, a number of initially introduced containers can also be recorded when the predetermined number of containers may have arrived at the packer.

[0027] Alternatively or additionally, the time that has elapsed since the first container reached the container conveyor and until the container conveyor reached the full state can be saved.

[0028] The recording of sensor data may further comprise recording first sensor data from a first sensor of a container conveyor, wherein the container conveyor may be one of the plurality of machines of the container treatment plant, wherein the first sensor data may indicate a full state of the container conveyor, or may comprise recording second sensor data from a second sensor of the container conveyor, wherein the second sensor data may indicate a half-full state of the container conveyor, or may comprise recording third sensor data from a third sensor of the container conveyor, wherein the third sensor data may indicate an empty state of the container conveyor.For example, a time can also be recorded at which the empty state, the half-full state, or the full state of the container conveyor can be reached, for example in relation to a starting time at which the initial introduction of the containers into the container handling system began.

[0029] Alternatively or additionally, the time that has elapsed since the first container reached the container conveyor and until the container conveyor reached the full state can be saved.

[0030] The recording of sensor data may further comprise recording sensor data from a sensor of a palletizer, wherein the palletizer may be one of the multiple machines of the container handling system, wherein the sensor data may indicate that a first container may have arrived at the palletizer. For example, a time at which the first container may have arrived at the palletizer may also be recorded, for example in relation to a starting time at which the initial introduction of the containers into the container handling system began. For example, a number of initially introduced containers may also be recorded when the first container may have arrived at the palletizer.

[0031] The initial loading of containers into the container handling system can be done using a depalletizer. The depalletizer can unload pallets and containers. The containers can be empty.

[0032] A container treatment plant for carrying out the method as described above or further below comprises several successive machines through which containers, such as plastic or glass bottles or cans, can pass, each machine being assigned at least one sensor for detecting containers.

[0033] The multiple consecutive machines may include at least two of: Depalletizer, first container buffer, filling and closing device, pasteurizer with a pasteurization area and a buffer area, second container buffer, packer, container conveyor, palletizer.

[0034] The first container buffer may comprise a mass conveyor, for example for empty containers.

[0035] The second container buffer may comprise a mass conveyor, for example for full containers. Short character description

[0036] The attached figure shows aspects and / or an embodiment of the invention by way of example for better understanding and illustration. It shows: Fig. 1 a schematic representation of a container treatment plant. Detailed character description

[0037] The Fig.1 shows a schematic representation of a container treatment plant 1 which here exemplarily comprises a depalletizer 2, a first container buffer 3 for empty containers, a separating device 4, a filling and closing device 5, a pasteurizer 6 comprising a pasteurization area 7 and a buffer area 8, a second container buffer 9 for full containers, a packer 10, a container conveyor 11 and a palletizer 12. The aforementioned machines are arranged one after the other, wherein further transport devices for the containers (not shown) can be arranged between the machines, such as separating devices or devices for bringing containers together.

[0038] Containers can pass through the container treatment plant 1 along a transport path 13. The transport path 13 can be slightly different for each individual container, for example at least for the first container buffer 3, the pasteurizer 6 comprising the pasteurization area 7 and the buffer area 8, and for the second container buffer 9. After the containers have been formed into bundles, the bundles can pass through the container treatment plant 1 along a transport path 13.

[0039] The depalletizer 2 comprises a first sensor 14 which can indicate that a pallet is present in the depalletizer 2.

[0040] A second sensor 15, which is arranged downstream of the depalletizer 2, is assigned to an inspection of the empty containers.

[0041] The first container buffer 3, which is located downstream of the depalletizer and can be configured as a mass conveyor, is assigned a third sensor 16, a fourth sensor 17, and a fifth sensor 18. These are arranged at corresponding positions of the first container buffer 3 along the transport path 13. The third sensor 16 can indicate a full state of the first container buffer 3, the fourth sensor 17 can indicate a half-full state of the first container buffer 3, and the fifth sensor 18 can indicate an empty state of the first container buffer 3.

[0042] A sixth sensor 19 can indicate a lock of the filling and closing device 5, which is arranged downstream of the first container buffer 3.

[0043] A seventh sensor 20 is associated with an inspection of the filled and closed containers, which is arranged downstream of the filling and closing device 5 or can be included in the filling and closing device 5.

[0044] An eighth sensor 21 is located at the inlet of pasteurizer 6, which is located downstream of the inspection. A ninth sensor 22 can indicate occupancy of buffer area 8 of pasteurizer 6. A tenth sensor 23 is located at the outlet of pasteurizer 6.

[0045] An eleventh sensor 24 is assigned to an inspection for containers that have left the pasteurizer. The inspection is located downstream of the pasteurizer 6.

[0046] The second container buffer 9 is arranged downstream of the inspection, with a twelfth sensor 25 indicating a full state of the second container buffer 9, a thirteenth sensor 26 indicating a half-full state of the second container buffer 9, and a fourteenth sensor 27 indicating an empty state of the second container buffer 9. The second container buffer 9 can be designed as a mass conveyor.

[0047] Downstream of the second container buffer 9, the packer 10 is arranged, at whose inlet a fifteenth sensor 28 and at whose outlet a sixteenth sensor 29 are arranged.

[0048] The container conveyor 11 is arranged downstream of the packer 10, wherein a seventeenth sensor 30 can indicate a full state of the container conveyor 11, an eighteenth sensor 31 a half-full state of the container conveyor 11 and a nineteenth sensor 32 an empty state of the container conveyor 11.

[0049] The palletizer 12 is arranged downstream of the container conveyor 11, with a twentieth sensor 33 being arranged at the inlet of the palletizer 12 and a twenty-first sensor 34 being arranged at the outlet of the palletizer 12.

[0050] For automatic calibration of the container handling system 1, one method can operate the container handling system 1 at 50% start-up speed. The initial insertion of containers can be performed by the depalletizer 2. The presence of a pallet in the depalletizer 2 can be detected by the first sensor 14. The depalletizer 2 can be used to unload pallets and containers at 50% capacity. The containers can be empty containers.

[0051] The containers can be inspected using the second sensor 15. For example, damaged containers can be ejected using a ejection device (not shown).

[0052] As more containers are introduced into the container treatment system 1, containers are moved to and onto the first container buffer 3, with the three sensors 16, 17, and 18 of the first container buffer 3 gradually responding. When the third sensor 16 indicates that the first container buffer 3 is full, the time elapsed since the first container was initially introduced into the container treatment system 1 can also be stored. Alternatively or additionally, the time elapsed since the first container was moved onto the first container buffer 3 and until the first container buffer 3 reached a full state can be stored; this time elapsed can be, for example, 100 seconds.

[0053] After the first container buffer 3 has been filled with containers, containers can be fed along the transport path 13 to the filling and closing device 5 via the separating device 4. The fill level of the first container buffer 3 thereby gradually decreases and can then be maintained at a fill level of 40%. The fill level of the filling and closing device 5 gradually increases due to the supplied empty containers and can then be maintained at a fill level of 50%.

[0054] After filling and closing, the full containers can be inspected using the seventh sensor 20. For example, incorrectly filled and / or closed containers can be ejected using a ejection device (not shown).

[0055] The full containers then reach the pasteurizer 6, where they can be pasteurized in the pasteurization area 7. At the entrance to the pasteurizer 6, the arrival of the full containers can be indicated by the eighth sensor 21. The fill level of the pasteurization area 7 gradually increases and is then maintained at 50%, or the speed can be adjusted to the percentage capacity. After pasteurization, the containers reach the buffer area 8 of the pasteurizer 6, which gradually fills. The fill level of the buffer area 8 can be indicated by the ninth sensor 22. When the fill level is 100%, the time that has elapsed since the first container was initially introduced into the container treatment system 1 can also be stored.Alternatively or additionally, the time elapsed from the time the first container entered the buffer area 7 until the fill level of the buffer area 8 reached 100% can be stored; this time can be, for example, 150 seconds. At the exit of the pasteurizer 6, the containers leaving the pasteurizer 6 can be indicated by the tenth sensor 23.

[0056] After leaving the pasteurizer 6, the containers can be inspected using the eleventh sensor 24. For example, containers that do not meet specified conditions can be ejected using a rejection device (not shown).

[0057] The pasteurized, full containers then gradually reach the second container buffer 9, which gradually fills. The buffer area 8 of the pasteurizer 6 gradually empties and is then maintained at a fill level of 50%. The three sensors 25, 26, and 27 of the second container buffer 9 can gradually respond. When the twelfth sensor 25 indicates that the second container buffer 9 is full, the time elapsed since the first container was initially introduced into the container treatment system 1 can also be stored. Alternatively or additionally, the time elapsed since the first pasteurized container reached the second container buffer 9 and until the second container buffer 9 reached the full level can be stored; this time can be, for example, 75 seconds.

[0058] After the second container buffer 9 has been filled with containers, containers can be fed along the transport path 13 to the packer 10, which can then pack the containers, for example, in groups of 6 into bundles. The second container buffer 9 is kept full. At the inlet of the packer 10, the arrival of the pasteurized full containers can be indicated by the fifteenth sensor 28. At the outlet of the packer 10, the bundles leaving the packer 10 can be indicated by the sixteenth sensor 29. The packer 10 is kept at 50% capacity.

[0059] The containers produced in the packer 10 then travel along the transport path 13 to and onto the container conveyor 11. The container conveyor 11 gradually fills with containers.

[0060] Accordingly, the three sensors 30, 31, and 32 of the container conveyor 11 can respond successively. When the seventeenth sensor 30 indicates that the container conveyor 11 has reached a full state, the time elapsed since the first container was initially introduced into the container handling system 1 can also be stored. Alternatively or additionally, the time elapsed since the first container reached the container conveyor 11 and until the container conveyor 11 reached the full state can be stored; this time can be, for example, 45 seconds.

[0061] After leaving the container conveyor 11, the containers reach the palletizer 12, where they can be picked onto pallets. The container conveyor 11 is kept full. At the entrance to the palletizer 12, the arrival of the containers can be indicated by the twentieth sensor 33. At the exit of the palletizer 12, the number of pallets picked with containers by the palletizer 12 can be indicated by the twenty-first sensor 34. The palletizer 12 can be kept at 50% capacity.

[0062] During automatic calibration, machine operating data can also be recorded. The sensor data and operating data can then be evaluated to create calibration data. The calibration data can then be used for subsequent operation of the container treatment system in an operating mode.
