Definitions
- the present invention relates generally to the field of forming containers of thermoplastic material from blanks, such as PET preforms, by a stretch-blow molding process.
- the invention is particularly applicable to rotary-type blow-molding machines having a plurality of blowing stations which are mounted on the periphery of a carousel.
- Each blowing station comprises, in particular, a blow mold, a blowing device (generally including a blowing nozzle) and a drawing device.
- the blowing mold is of the wallet type, that is to say it comprises two parts s Opening by spacing by pivoting about a common axis.
- a blank pre-heated to a softening temperature is placed in a blow mold which bears the impression of the container to be obtained.
- a blowing nozzle is placed in communication with the opening of this blank and a blowing fluid is injected under high pressure to press the material of the blank against the walls of the cavity of the blow mold.
- a rod comes to stretch the blank in the blow mold and press against the bottom wall of the blank.
- the drawing rod is conventionally introduced into the opening (the neck) of the blank to stretch and blow. This rod slides axially in the longitudinal axis of the blowing nozzle, an annular space being left free to allow the passage of the blowing fluid.
- blowing is not done in abstracto, but that the operations performed during the blowing as well as the parameters of the machine (such as the temperature of the mold) depend on the intended use of the container.
- the setting parameters of the mold temperature depend, in particular in the case of containers designed for hot fill "hot fill", the temperature of the filling liquid of said containers.
- the function of the mold temperature is to freeze as quickly as possible the shape of the container, which temperature is, for example, of the order of 10 ° C.
- This temperature of the mold will, for example, be order of 65 0 C to obtain a volume shrinkage of the container at the machine outlet, which is almost identical to the shrinkage obtained after natural aging of said container.
- the hot fill for example with liquids such as tea, pasteurized fruit juice, etc.
- the pasteurization of the content assumes that the mold is heated to a predetermined temperature, in order to thermofixing the material, as described in document FR2649035.
- the mold is put in temperature (cooling or reheating) by a circulation of a coolant (water or hot oil in the case of heating) in ducts formed in the wall of said mold, around the mold cavity.
- a coolant water or hot oil in the case of heating
- the temperature of the molds is between 120 and 160 0 C while that of the blanks is about 120 ° C.
- contacting the blown material constituting the blank tends to cool the skin of the molding cavity (that is to say the outer surface of the molding cavity corresponding to the first millimeters in depth of the inner surface of the molding cavity).
- This skin temperature of the molding cavity stabilizes after several blowing cycles and therefore after several contacting of the softened material blown from the blank on the blowing cavity.
- the first containers blown into a blow mold are not at a constant temperature of the mold, which ultimately results in containers with different volume capacities.
- the final volume of the bottle is smaller than the volume of the mold cavity. But the temperature of the mold has an influence on the final volume of the bottle. In fact, the colder the mold, the greater the volume of the bottle.
- Document FR2881979 proposes a method of controlling a container blowing machine intended to correct certain anomalies, such as the distribution of material. Means are implemented to continuously monitor, during production, the thickness of the wall of the containers that come out of the various molds.
- This intervention is performed a posteriori, during the production of the containers.
- the present invention makes it possible to intervene from the beginning of the production to avoid rejects related to the start-up phase of the blowing machine, which rejects all the same on several hundred containers.
- the present invention relates to a method of forming containers from a preform, preferably a preform, of thermoplastic material, the containers being formed using a rotary type stretch-blow molding machine comprising at least one blow mold, mounted on the periphery of a carousel driven continuously about its axis, the blow mold operating cyclically according to a blow cycle comprising the following steps: a step of placing a preheated blank in a blow mold having, in the closed position, a mold cavity forming the impression of the container to be blown,
- a step of drawing the blank by inserting an extension rod inside the blank while bearing against the bottom of the blank so as to facilitate the axial elongation of the blank a step of scanning the inside of the container by injection of a cooling gas, in particular air,
- the method comprises a step of setting a value of the scanning time Td which is used for the first revolution of the carousel of the blowing machine.
- the method comprises a step of setting the duration of the compensation period, which duration, or compensation time Tc is of the order of a few minutes, that is to say a sufficient time for the dimensional evolutions of the blown containers to become negligible or even nil.
- the coefficient A is of the order of 0.0003 to 0.0006; it is negative when the temperature of the molds decreases during the period Tc of compensation and it is positive when the temperature increases during said period Tc compensation.
- the method consists in producing, during the compensation period, an automatic change in the duration of the scanning time, incrementally, at each turn, for example, of the carousel of the blow-stretching machine.
- the invention also relates to the installation, and in particular the blow-stretching machine which makes it possible to implement the previously detailed method, which machine comprises a PLC and means for inserting - a scanning time Td for starting the machine. machine and in particular the first round of the carousel, - a time Tc for the compensation period, and - a correction coefficient A which, during the compensation period Tc, changes the scanning time JJb.
- the machine comprises means, at the level of the automaton, for varying the duration of the scanning time Tb incrementally, at each carousel revolution of the machine, for example.
- FIG. 1 illustrates the state of the art figuratively, and in particular the variations of the volume V of the containers formed, the scanning time Tb and the temperature T of the blowing mold, starting from FIG. starting up the machine and during the production of the containers, in the case of a manufacture which sees the temperature of the mold fall during the first minutes of manufacture of said containers
- FIG. 2 illustrates, in the same way, the variations of the volume V of the containers formed, the swathing time Tb and the temperature T of the blow mold, for a blow-molding machine operating according to the method. of the invention
- FIG. 1 illustrates the state of the art figuratively, and in particular the variations of the volume V of the containers formed, the scanning time Tb and the temperature T of the blowing mold, starting from FIG. starting up the machine and during the production of the containers, in the case of a manufacture which sees the temperature of the mold fall during the first minutes of manufacture of said containers
- FIG. 2 illustrates, in the same way, the variations of the volume V of the containers
- FIG. 3 also illustrates the state of the art and, as previously, the variations of the volume V of the containers formed, the scanning time Tb and the temperature T of the blow mold, but in the case of a manufacture which sees, on the contrary, increase the temperature of the mold during the first minutes of manufacture of said containers, - Figure 4 illustrates, in the case of Figure 3, the variations - of the volume
- V of the container formed V of the container formed, - sweeping time Tb and - temperature T ⁇ of the blow mold, but for a blow-stretching machine operating according to the method of the invention.
- the present invention relates to the improvement of a process for forming containers from a preform, preferably a preform, of thermoplastic material, the containers being formed using a stretch-blow molding machine.
- rotary valve comprising at least one blow mold, mounted on the periphery of a carousel driven continuously about its axis, the blow mold operating cyclically according to a blow cycle comprising the following steps:
- a step of closing the blow mold a step of blowing the blank into the blow mold via a blowing nozzle and, substantially simultaneously, a step of drawing the blank by inserting a drawing rod at the interior of the blank resting against the bottom of the blank so as to facilitate axial elongation of the blank;
- a step of scanning the inside of the container by injecting a gas, and in particular air, through a plurality of orifices provided in the elongation rod, in order to cool the container;
- the temperature T 1 of a blow mold decreases at the beginning of the production of the containers. This decrease in the temperature of the inner wall of the mold, following the start of the machine, comes from the contacting of the preform with said inner wall of said mold. Indeed, in some cases of manufacture, as detailed before, the softened material of the preform is colder than the temperature of the wall of the mold cavity of the blow mold (see the bottom curve of Figure 1).
- the scanning time Tb is constant throughout the operation of the blow mold (see middle curve of FIG. 1); this scanning time Tb has a value Td which is normally programmed before starting the machine and it is maintained for the duration of the production of the containers.
- the volume variation of the formed container between the beginning of mold production and the instant when the temperature of the mold is stable, is between 5 and 10%.
- the duration of the sweeping step is dependent on the number of blowing cycles performed by the blow mold following the start of the first blow molding cycle of the blow mold; whereby the temperature variation of the skin of the molding cavity is taken into account due to the temperature difference between the skin temperature of the molding cavity and the temperature of the heated blank coming into contact with the mold cavity.
- said molding cavity during the blowing step which leads to the manufacture of containers having a more stable internal volume over time and, more particularly, at the beginning of production of the blow mold.
- the method according to the invention thus comprises a step which consists in programming a period of temporary evolution of the scanning time, that is to say a compensation period during which the duration Tb of the scan will be greater than the duration which is that of the stabilized production.
- This compensation period Tc corresponds to the period of time during which the temperature of the molding cavity changes until the temperature of this cavity is stabilized, that is to say between the start of production and the moment when we can talk about cruising speed for the blowing machine.
- the compensation time Tc that is to say the time during which the temperature of the skin the mold cavity evolves before stabilizing; this compensation time Tc is, for example, set at 180 seconds.
- the method also comprises a step of setting the maximum variation of the scanning time Tb.
- the value of said scanning time Tb decreases automatically, FIG. 2, to stabilize when the compensation period Tc is over and the machine is running at cruising speed. .
- this compensation time Tc determined and fixed is determined and set a scanning time Tb which takes into account the displayed value Td for the first blowing cycle, or the first round of the carousel.
- This scanning duration Tb changes with time and it corresponds to the application, for example, of a simple equation of the 1st degree of the type Tb - At + Td, where Td is the scanning time introduced into the automaton for the first round of the carousel and where A is a coefficient which depends on the conditions of use of the blowing machine and the containers to be shaped and whose value ranges from 0.0003 to 0.0006; Tc corresponds to the duration of the compensation period and its value varies.
- t takes a value that changes, for example, incrementally between Tc and zero; Tc can have a value chosen between 2 to 3 minutes.
- the evolution of the scanning time Tb can therefore be established, preferably, with a linear variation during the compensation time Tc (see middle curve of FIG. 2).
- the scanning time Tb is constant; it corresponds to: A.Tc + Td with, for the coefficient A, a negative value considering the fact that the temperature of the molds, at the beginning, is higher than that of the preforms and that it decreases in contact with them before stabilize.
- FIG. 3 and 4 illustrate the variations that can be seen in the case of a shaping of containers where the temperature of the molds is lower than that of the preforms, that is to say that the molds are heated and their temperature T ⁇ evolves in contact with the preforms (bottom curve of FIG. 3), which results in a decrease in the volume V of the bottles (top curve of the same FIG. 3) between the start of production and the operation in cruise regime.
- FIG. 3 shows these variations of V and T ⁇ which can be seen with the state of the art for which the scanning time Tb is initially fixed with a value Td which remains constant throughout the production of containers.
- FIG. 4 shows the stability of the volume V of the containers obtained by the application of the method according to the invention.
- this time Tb evolves incrementally at each carousel revolution, for example, and at the end of the compensation period Tc, the scanning time Tb is equal to: A.Tc + Td with a coefficient A which is positive, between 0.0003 and 0.0006.
- the evolution of the scanning time Tb also has an influence on the overall time of the shaping cycle of the containers.
- the scan time Tb evolves to a decrease which increases, for example, the time of maintaining the blowing pressure during the cruise regime.
- This corrected scanning time Tb is of the order of a few fractions of a second; it varies between these fractions of a second at the beginning of the production of the containers and zero at the end of the period Tc of compensation, when the temperature of the molds is stabilized and when the dimensional evolutions of the blown containers become negligible, or even zero.
- the duration of the scanning time Tb, during the compensation period Tc is modified at regular time intervals and automatically, and even more preferably, the duration of the scanning time, during the compensation time Tc, is changed after each complete revolution of the blow mold on the carousel incrementally.
