Description

[0001] Device and system for manufacturing at least one container, container manufacturing machine and method for controlling at least one container manufacturing machine

[0002] The invention relates to a device and a system for manufacturing at least one container, a container manufacturing machine and a method for controlling a container manufacturing machine.

[0003] In the production of containers, preforms made of a thermoplastic material can be used, from which the containers can be formed. Before forming, the preforms can first be thermally conditioned. Afterwards, they can be formed into containers in a forming machine using a pressurized fluid in container molds.

[0004] The forming process can be multi-stage. First, as known from US 2019 / 0315039 A1, a fluid at a pre-pressure can be introduced into the preform. Then, a fluid at a higher pressure (P1) can be introduced into the preform to expand it. After expansion, the container can be formed by introducing a fluid at an even higher pressure (P2) into the expanded preform to press its walls against the inner walls of the mold. Providing these high pressures, which can reach up to 45 bar, requires significant energy, which can be costly. Therefore, the shortest possible fluid lines with the largest possible cross-sections are used to minimize friction losses.

[0005] The object of the invention is to provide a device for manufacturing at least one container and a method by which energy and thus costs can be saved. This object is achieved by the features of the independent claims. Advantageous embodiments are the subject of the dependent claims and the following description.

[0006] In a device for producing at least one container from at least one preform, comprising at least one fluid valve for fluid-communicating connection with at least one mold for forming the at least one preform, at least one fluid source outlet for at least one fluid under an outlet pressure, and at least one fluid line, wherein the at least one fluid line fluid-communicatingly connects the at least one fluid valve and the at least one fluid source outlet, it is provided according to the invention that the at least one fluid line is designed such that a first overshoot of a pressure of the fluid flowing from the at least one fluid source outlet into the at least one mold after reaching the outlet pressure in the mold has a maximum value that is at least 10% greater than the outlet pressure.

[0007] The device thus enables a pressure increase in the blow mold or in a preform inserted into the blow mold, at least in the phase immediately after the fluid reaches the outlet pressure, which is at least 10% above the outlet pressure. For example, if the outlet pressure at the fluid source outlet is 40 bar, the initial overshoot can have a maximum value of at least 44 bar. After the initial overshoot subsides, the pressure in the container can stabilize at the outlet pressure. The pressure increase via the initial overshoot of the fluid pressure is achieved passively through the design of the fluid line. The fluid line can be designed such that the impulse of the fluid upon introduction into the blow mold or a preform inserted into the blow mold is increased compared to the prior art.The momentum increase can be achieved by increasing the moving mass of the fluid within the fluid line and / or increasing the fluid flow velocity within the fluid line. It is advantageous to increase both the moving mass and the fluid flow velocity within the fluid line. This increases the initial overshoot after reaching the outlet pressure to a maximum value at least 10% greater than the outlet pressure, enabling the forming of the vessel. Furthermore, the outlet pressure can then be lower than in the prior art, thus reducing the energy required to generate the pressure. For example, if a pressure of 40 bar is required to form the vessel, an outlet pressure of only approximately 36.36 bar can be provided.The higher the maximum value of the first overshoot curve above the outlet pressure, the more energy can be saved. Accordingly, operating costs can be reduced, and, for example, a less powerful compressor can be used to generate the outlet pressure, which can therefore also be more cost-effective.

[0008] The aforementioned pressure values ​​are to be understood as examples for illustrative purposes and can be arbitrarily chosen, if technically feasible, as to be set in the preform.

[0009] According to some embodiments, it is conceivable that the maximum value of the first overshoot curve can be at least 12%, preferably at least 15%, and more preferably at least 18% greater than the outlet pressure.

[0010] This allows for increased energy and cost savings. If the maximum value of the first overshoot curve is at least 12% greater than the outlet pressure, it can reach a value that is 1.12 times the outlet pressure. The same applies to the other specified relative values.

[0011] In some embodiments, the first overshoot curve can have a maximum value that is at most 100%, preferably at most 80%, further preferably at most 50%, further preferably at most 30%, further preferably at most 20% greater than the outlet pressure.

[0012] According to some embodiments, it is conceivable that the at least one fluid line can have a length that is greater than the distance between the fluid source outlet and the fluid valve, which connects the at least one fluid line in a fluid-communicating manner.

[0013] In this way, the mass of the fluid in the fluid line can be increased. The distance between the fluid source outlet and the fluid valve refers to the shortest possible distance. For example, if the fluid valve is located 1 m in a straight line from the fluid source outlet, the fluid line, according to the last-mentioned embodiments, is longer than 1 m. By increasing the mass of the fluid in the fluid line, the momentum of the fluid when introduced into the container placed in a blow mold can be increased using simple means.

[0014] According to some embodiments, it is conceivable that the fluid line can extend at least partially in a helical and / or spiral shape between the at least one fluid source outlet and the at least one fluid valve.

[0015] When using spiral fluid lines, the fluid lines can extend spirally around the fluid source outlet, starting from the fluid source outlet. The fluid source outlet can be oriented in a different direction than the direction from the fluid source outlet to the fluid valve.

[0016] When using a helical fluid line, an existing container manufacturing machine can be retrofitted with the device described above. The existing fluid lines can be replaced with the helical fluid lines, thus increasing the mass of the flowing fluid in each line. This allows for a simple increase in the fluid's momentum as it enters the container.

[0017] According to some embodiments, it is conceivable that the nominal diameter of the at least one fluid line can be less than or equal to 20 mm, preferably less than 18 mm, and more preferably less than 15 mm. By reducing the nominal diameter of the fluid line, the flow velocity of the fluid can be increased when it is introduced into a container or preform placed in a blow mold. By increasing the flow velocity, the momentum of the fluid when introduced into the container or blow mold can be increased using simple means.

[0018] Here too, an existing container manufacturing machine can be retrofitted with the device by replacing the existing fluid lines with fluid lines of a smaller nominal diameter.

[0019] According to some embodiments, it is conceivable that the outlet pressure can have a value between 20 bar and 45 bar, preferably a value between 20 bar and 40 bar, and more preferably a value between 22 bar and 40 bar.

[0020] The outlet pressure can therefore be the so-called P2 pressure, which can be used for forming the containers in the mold. Since the P2 pressure is usually the highest pressure used, increasing the maximum value of the first overshoot of the pressure can result in particularly large energy savings.

[0021] However, the invention can be provided for any pressure level.

[0022] According to some embodiments, it is conceivable that at least one further fluid line can connect the at least one fluid source outlet and the at least one fluid valve in parallel to the at least one fluid line in a fluid-communicating manner, wherein the at least one further fluid line can be designed such that the first overshoot curve after reaching the outlet pressure can have a maximum value that can be less than 1.1 times the outlet pressure.

[0023] This allows at least two fluid lines to provide a fluid-communicating connection between the fluid source outlet and the fluid valve. Each fluid line can be controlled by its own valve. Therefore, the height of the initial overshoot can be adjusted depending on the requirements for manufacturing the containers.

[0024] Furthermore, in some embodiments, it is conceivable that several fluid lines can be used, designed such that one value of the first overshoot curve exceeds 10% of the outlet pressure. However, the fluid lines can provide different maximum values ​​for the first overshoot curves.

[0025] According to some embodiments, it is conceivable that the device may have at least one control device for the fluid valve, wherein the control device is designed to close the fluid valve during the first overshoot phase.

[0026] By closing the fluid valve during the first overshoot phase, the pressure generated by this phase can be maintained within the mold or the container placed in the mold. This prevents the pressure from dropping to the outlet pressure. Despite the lower outlet pressure, the container being produced can still be formed with the increased pressure generated by the first overshoot phase.

[0027] In some embodiments, the timing for closing the valve can be stored electronically in a control unit. For example, during a test run, it can first be determined when the signal to close the valve must be provided so that the fluid valve closes as close as possible to when the first overshoot curve has essentially reached its maximum value.

[0028] In some further embodiments, a sensor can monitor the pressure curve in order to issue the closing signal in a timely manner, such that the fluid valve closes as close as possible to when the first overshoot curve has essentially reached its maximum value. According to a second aspect, the invention relates to a container manufacturing machine comprising a plurality of blow molding stations, each with at least one mold, at least one device as described above, and at least one fluid distributor, wherein the at least one fluid source outlet of the at least one device is fluidly connected to the fluid distributor, and the at least one fluid valve of the at least one device is configured for fluidly communicating connection with at least one mold of the plurality of blow molding stations.

[0029] The advantages, effects, and further developments of the system result from the advantages, effects, and further developments of the device described above. To avoid repetition, reference is therefore made to the preceding description in this regard.

[0030] According to a third aspect, the invention relates to a plant for manufacturing at least one container comprising at least one container manufacturing machine according to the preceding description, at least one transport device and at least one container treatment machine, wherein at least one transport device is designed for transporting containers and / or preforms between the at least one container manufacturing machine and the at least one container treatment machine.

[0031] The advantages, effects, and further developments of the system result from the advantages, effects, and further developments of the device and treatment machine described above. To avoid repetition, reference is therefore made to the preceding description in this regard.

[0032] According to a fourth aspect, a method for controlling at least one container manufacturing machine is described, comprising at least the following steps: inserting a preform into a mold for at least one container; closing the mold and fluidically connecting a fluid valve of a device according to the preceding description to an opening of the preform; opening the fluid valve to admit a fluid at an outlet pressure into the preform for expanding the preform in the mold; characterized by generating a first overshoot of the pressure of the fluid flowing from the at least one fluid source outlet into the at least one preform after reaching the outlet pressure, wherein the first overshoot in the mold has a maximum value that is at least 10% greater than the outlet pressure.

[0033] According to some embodiments, it is conceivable that the method may further include at least the following step: closing the fluid valve during the first overshoot phase.

[0034] The advantages, effects, and further developments of the process result from the advantages, effects, and further developments of the device, treatment machine, and system described above. To avoid repetition, reference is made to the preceding description in this regard.

[0035] The invention is described below with reference to an exemplary embodiment and the accompanying drawing. The drawing shows:

[0036] Figure 1a-c shows a schematic representation of a device;

[0037] Figure 2 shows a schematic representation of a fluid line;

[0038] Figure 3a, b shows a diagram of the pressure profile in a preform placed in a blow mold in various embodiments; and

[0039] Figure 4 shows a schematic representation of a container manufacturing machine;

[0040] Figure 5 shows a schematic representation of a plant;

[0041] Figure 6 shows a flowchart of the process. The apparatus as a whole is referred to below by reference numeral 10, as shown in Figures 1a to 1c.

[0042] As shown in Figure 1a, the device 10 for producing at least one container from at least one preform 11 has at least one fluid valve 12 for fluid communication with at least one preform 11 inserted in a mold 14. The mold 14 can be configured to form the preform 11 into a container, for example a bottle. For this purpose, the mold 14 can include a complementary contour 15 of the outer shape of the container to be produced.

[0043] A fluid-communicating connection between the fluid valve 12 and the preform 11 can be established, for example, by placing the fluid valve 12 on an opening of the preform 11. This is illustrated by way of example in Figure 1c.

[0044] Furthermore, the device 10 has at least one fluid source outlet 16 at which a fluid, for example, a blowing gas or a filling material for the container to be manufactured, can be supplied at an outlet pressure P2. A fluid line 18 of the device 10 provides a fluid-communicating connection between the fluid valve 12 and the fluid source outlet 16. According to Figure 2, the fluid line 18 has a nominal diameter 30. In some embodiments, the fluid line 18 can be designed as a pipe or as a hose.

[0045] By opening the fluid valve 12, the fluid can flow from the fluid source outlet 16 through the fluid line 18 and the fluid valve 12 into the preform 11, which is connected to the fluid valve 12 in a fluid-communicating manner. The pressure profile 50 in the preform 11 over time is shown in Figure 3a. The pressure profile 50 shows that after reaching the outlet pressure P2, a pressure overshoot occurs with a first overshoot profile 52, which is shown in Figure 3a.

[0046] The fluid line 18 is designed such that the first overshoot curve has a maximum value 54 that is at least 10% greater than a value of the outlet pressure P2. In some embodiments, the maximum value 54 can preferably be at least 12%, preferably at least 15%, and more preferably at least 18% greater than the outlet pressure P2.

[0047] The fluid line 18 can, for example, have a nominal diameter 30, which increases the flow velocity of the fluid flowing through the fluid line 18 after exiting the fluid source outlet 16. The nominal diameter 30 can, for example, be less than or equal to 20 mm, preferably less than 18 mm, and more preferably less than 15 mm. By increasing the flow velocity of the fluid in the fluid line 18, the momentum of the fluid as it flows into the preform 11 inserted into the mold 14 can be increased. In this way, after reaching the outlet pressure P2, the pressure overshoot can be amplified so that the first overshoot 52 can become so large that the maximum value 54 of the first overshoot 52 is at least 10% of the outlet pressure P2.

[0048] Alternatively or additionally, the length of the fluid line 18 can be such that it is greater than the distance 13 between the fluid source outlet 16 and the fluid valve 12. The distance 13 is to be understood as the shortest distance between the fluid valve 12 and the fluid source outlet 16 and can, for example, correspond to the straight-line distance between these two elements.

[0049] In some embodiments, the length of the fluid line 18 can be more than 1.5 m, preferably more than 1.6 m.

[0050] The fluid line 18 can extend, at least in sections, in a spiral shape around the fluid source outlet 16, as shown by way of example in Figure 1a. Alternatively or additionally, the fluid line 18 can also be designed to meander or curve in order to increase the length of the fluid line 18 compared to the distance between the fluid valve 12 and the fluid source outlet 16.

[0051] In some further embodiments, the fluid line 18 can be helically shaped, as shown by way of example in Figure 1b. The fluid line 18 can, for example, extend helically from the fluid source outlet 16 to the fluid valve 12. By increasing the length of the fluid line 18, the mass of the fluid contained within it can be increased. This increased mass of the fluid in the fluid line 18 also increases the momentum of the fluid flowing through it. As explained above, this increase in momentum can increase the pressure overshoot in the possibly expanded preform 11 after reaching the outlet pressure P2.

[0052] In this embodiment, the outlet pressure corresponds to the so-called P2 pressure of a blow stretching process. However, this does not preclude the outlet pressure from being a different pressure, such as the so-called PI pressure of the blow stretching process or a pre-pressure PO of the blow stretching process. The first overshoot then corresponds to the first overshoot after the respective outlet pressure used.

[0053] In some embodiments, the device 10 may further include an additional fluid line 28, which provides a fluid-communicating connection between the fluid source outlet 16 and the fluid valve 12. The additional fluid line 28 can be used alternatively or additionally to the fluid line 18 to convey fluid from the fluid source outlet 16 to the fluid valve 12. The device 10 can therefore be configured such that, for example, either the fluid line 18 or the additional fluid line 28, or both fluid lines 18 and 28, can be used via valves.

[0054] The additional fluid line 28 can be configured such that a first overshoot curve 52, after reaching the outlet pressure P2, has a maximum value that is less than 10% greater than the outlet pressure P2. Alternatively, the additional fluid line 28 can also be configured such that it provides a first overshoot curve 52, after reaching the outlet pressure P2, with a maximum value that is at least 10% greater than the outlet pressure P2 and differs from the maximum value of the first overshoot curve 52 of the fluid line 18. This allows different maximum values ​​for the first overshoot curves 52 to be used for forming containers, depending on the application.

[0055] As can be seen in Figure 3a, the pressure in the preform 11 can drop to the outlet pressure P2 after the first overshoot 52. A settling-in process with further overshoots can then occur.

[0056] The fluid valve 12 can be controlled by a control device 20 such that it can be closed during the first overshoot phase 52. For this purpose, the control device 20 can be connected to the fluid valve 12 via wireless or wired signal connections 24, 26. Thus, the fluid valve 12 can be closed at time 58 when a maximum of the first overshoot phase 52 is reached. This is illustrated by way of example in the pressure curve 56 of the diagram in Figure 3b. The pressure curve from Figure 3a is shown as a dashed line.

[0057] Furthermore, a sensor 22 can be provided with which the pressure at the fluid valve 12 and / or in the fluid line 18 can be measured. This allows, for example, the determination of when the fluid valve 12 must be closed in order to release the pressure.

[0058] Alternatively, the switching time for the fluid valve 12 can be stored in the control unit 20 or in a memory to which the control unit 20 has access.

[0059] The pressure generated in the preform 11 by the first overshoot curve 52 can thus be contained by closing the fluid valve 12 in the preform 11. After closing the fluid valve 12, the pressure in the preform 11 is greater than the outlet pressure P2. In this way, an outlet pressure P2 can be provided for the forming process of the preform that is lower than the pressure required in the preform 11 for the forming process. Consequently, a pressure generation unit for the outlet pressure P2, in particular a compressor, can be designed for a lower pressure than is required for forming the preform 11.

[0060] Figure 4 shows a schematic representation of a container manufacturing machine 32. The container manufacturing machine 32 has a plurality of blowing stations 34 arranged on a blowing wheel. The blowing wheel, and thus the container stations 34, are rotatably mounted about an axis 33. At least one of the blowing stations 34 can be assigned a device 10 as described above. In this embodiment, each blowing station 34 is assigned a device 10.

[0061] The fluid valves 12 of the devices 10 can be arranged at the blowing stations 34. Furthermore, each blowing station 34 can have at least one mold 14. The fluid valves 12 can be designed such that they can be arranged on an opening of preforms 11 inserted into the respective molds 14 and can be fluidly connected to the preforms 11.

[0062] The container manufacturing machine 32 further comprises a rotary distributor 36 for the fluid. The rotary distributor 32 can be fluid-communicating with a pressure generation unit (not shown) for the fluid. The rotary distributor 32 can be arranged on the axis 33. Furthermore, the fluid source outlets 16 of the devices 10 are attached to the rotary distributor 32 and fluid-communicating with the rotary distributor 32.

[0063] In this embodiment according to Figure 4, the fluid lines 18 extend at least partially in a spiral shape around the rotary distributor 36. Along their length, the fluid lines 18 rotate through an angle of approximately 180°. However, this does not preclude the fluid lines 18 from also sweeping a different angle around the rotary distributor 36 or the fluid source outlets 16. Furthermore, the fluid lines 18 can also have several turns around the rotary distributor 36.

[0064] Figure 5 shows a system 38 for manufacturing at least one container. The system 38 comprises at least one container manufacturing machine 32 as described above. Furthermore, the system 38 can comprise at least one container treatment machine 44. In this embodiment, the container treatment machine 44 can, for example, have a heating section for preforms 11, in which the preforms 11 can be thermally conditioned for the forming process in the container manufacturing machine 32.

[0065] A transport device 40, 42, 46, 48 of Annex 38 can transport the containers or preforms 11 between the at least one container treatment machine 44 and the at least one container manufacturing machine 32. The transport device 40, 42, 46, 48 can, for example, have rotatably mounted transport stars on the circumference of which the preforms 11 or containers are held and can be moved by rotating the transport stars. Alternatively or additionally, the transport device 40, 42, 46, 48 can also have conveyor belts or inclined rails along which the preforms 11 can be conveyed or slide. The transport mechanism can also have other configurations with which the preforms 11 can be transported.

[0066] Figure 6 shows a flowchart of the process 100 for controlling at least one container manufacturing machine 32.

[0067] According to a first step 102, a preform 11 can be placed in a mold 14 in which the preform 11 can be transformed into a container.

[0068] In a further step 104, a fluid valve 12 can be fluidly connected to an opening of the preform 11 inserted in the mold 14. The fluid valve 12 can be part of a device 10 as described above.

[0069] In a further step 106, the fluid valve 12 can be opened to introduce fluid into the preform 11. The fluid can be at an outlet pressure P2 and supplied to the device 10 via the fluid source outlet 16 and the fluid line 18 described above.

[0070] By introducing the fluid, the preform 11 can be expanded into a container in the mold 14. According to a further step 108, after reaching the outlet pressure P2 in the expanded preform 11, a first overshoot curve 52 is generated, which has a maximum value that is at least 10% greater than the value of the outlet pressure P2.

[0071] In an optional further step 110, the fluid valve 12 can be closed during the first overshoot phase 52. In this way, the pressure generated by the first overshoot phase 52, which is greater than the outlet pressure P2, can be contained in the preform 11.

[0072] The example described above in no way limits the invention. Rather, the invention can be modified in numerous ways. All features of the invention described above can be essential to the invention, either individually or in combination.
