Definitions
- the invention relates to improvements made to methods and installations for manufacturing containers, made of thermoplastic materials, such as bottles, having a bottom comprising a curved central part, with a convexity facing inwards, from blanks having themselves a bottom comprising a curved central part with an inwardly turned convexity, the method comprising at least one step of heating at least the body of the blank to bring the thermoplastic material to its softening temperature, a step during which the blank is positioned in a finishing mold arranged to obtain the final container, and in particular having a mold base with a vaulted central part whose shape and dimensions allow it to be introduced into the hollow of the bottom of the blank, and a step of finishing by blowing the blank during which the part centers the arched bottom of the mold is introduced into the central hollow part of the bottom of the blank.
- an intermediate container having larger dimensions is molded by blow molding or stretch blow molding, from a preform of thermoplastic material, the body of which is brought to a temperature at least equal to the softening temperature of the material. those of the final container to be obtained; this intermediate container is then heat treated to obtain a blank with a hot shrunk body, which is then molded to form the final container.
- the containers having the best mechanical or thermal characteristics for use are those obtained from a blank having at least one primer of the central part, curved, with a convexity turned inwards, bottom of the final container. It has even been found in certain applications that the blank must have a bottom whose shape and dimensions must correspond to those of the bottom of the final container to be obtained.
- the blank is obtained in the open air, after having strongly heated the body of the intermediate container and thus caused a relaxation of the stresses induced in the thermoplastic material during the transformation of the preform into an intermediate container.
- the blank resembles a container whose body is vaguely deformed or blistered, but which nevertheless has a bottom zone with a shape and dimensions determined by the process used, that is to say either the shape and dimensions of the bottom of the final container, ie a primer for the central part of the final bottom.
- the axis of symmetry of the bottom zone is offset and / or inclined relative to the axis of the finishing mold at the when the blank is placed in the latter.
- the positioning of the blank in the finishing mold is carried out in a known manner using the neck (of the neck) which is the only part which does not undergo any deformation during the different stages of transformation of a preform in a container.
- the object of the invention is therefore to remedy these drawbacks, by proposing a method and an installation making it possible to obtain correct centering of the central, curved area of the blank relative to the arched part of the mold base.
- the objects of the invention are achieved by implementing a method as indicated in the preamble which is characterized in that, to facilitate centering of the bottom of the blank relative to the central, arched part, of the mold bottom at the time of their contact, a relative rotational movement between the arched part of the mold base and the central part of the blank is caused between the moment when the blank is placed in the mold and that when said parts are correctly positioned l 'one over the other.
- the relative rotational movement is caused by driving in rotation at least the central, arched part of the mold base.
- the relative movement is obtained by putting the blank in rotation relative to the mold.
- the invention also relates to an installation for implementing the method, characterized in that it comprises means for causing the relative rotation of the blank and the mold base.
- the means for causing the relative rotation between the blank and the central part of the mold base are constituted by a pneumatic rotary motor, driving said central part.
- a pneumatic rotary motor driving said central part.
- the mold bases are generally movable in a direction oriented along the axis of the mold, at least to facilitate the positioning of the blank and to facilitate the demolding of the container; in other cases, the mold bases are moved along the same axis during the finishing phase, as is the case in French application No.
- FIG. 1 and 2 illustrate, each schematically, different possible steps of a method of manufacturing containers from a preform, transformed into an intermediate container, itself heat treated to obtain a blank before blowing the container final;
- Figures 3A to 3C and 4A to 4C illustrate, schematically, two variants of an installation for implementing the method of the invention.
- Figures 1 and 2 illustrate known steps of manufacturing a container having a returning bottom through a finishing step of blowing a blank.
- An initial preform 1 is placed, after having undergone an appropriate heat treatment to soften the thermoplastic material constituting it, in a first mold (not shown) in which it is blown or stretched then blown, to obtain an intermediate container 2 having a bottom with a hollow part 3, with convexity facing the interior of the container 2.
- the intermediate container 2 then undergoes a heat treatment which makes it possible to release the stresses induced during the blowing (or the stretch blowing), which leads to a hot blank 4 with a body narrowed longitudinally and transversely with respect to the intermediate container.
- the blank 4 then undergoes an appropriate heat treatment to allow it to be treated in a finishing mold (not shown) allowing the final container 5 to be obtained.
- the neck 6 of the final container corresponds, in shape and in dimensions, to that of the preform. It does not undergo dimensional changes during the various stages of transformation.
- a particular heat treatment can be applied to the blank 4 and to the neck 6 thereof to significantly increase the degree of crystallinity of the final container 5 compared to what can be obtained by a conventional blowing process.
- the invention is particularly suitable for the manufacture of containers capable of withstanding severe thermal or mechanical constraints of use.
- the phase of release of stresses leading to the blank 4, from the intermediate container 2 often leads to a blank 4 whose axis 8 of symmetry of the hollow part 3 of the bottom is offset axially and / or inclined relative to the axis 9 of symmetry of the neck which corresponds to the axis of symmetry of the assembly of the final container 5.
- the mold used during the finishing phase comprises a bottom with a vaulted part intended to penetrate into the hollow part 3 of the bottom of the blank, in order to avoid uncontrolled deformation of this hollow part.
- the mold base is movable in an axial direction and is brought into contact with the bottom of the blank during the finishing phase.
- the base of the mold can be brought into contact with the blank immediately upon closing the mold, or alternatively, as described in the French patent application published under the number 2 714 631 at name of the applicant, the base of the mold can be brought into contact with the base during the final blowing.
- a first solution consists in rotating the blank relative to the mold.
- This solution can only be envisaged if the mold base is brought into contact with the bottom of the blank when the mold is closed. In fact, after closing, as soon as the finishing blowing begins, there is swelling of the shoulder and of the body of the blank which come into contact with the walls of the molding cavity. Consequently, if the solution which consists in rotating the blank is retained, the rotation must immediately be stopped before this arrival in contact with a part of the shoulder or of the body with the walls of the mold, otherwise the final container will be of poor quality.
- FIGS. 3A to 3c and 4A to 4C consist in forming the mold base so that the arched central part 10 of the bottom
- the mold base 11 movable axially along the axis of the finishing mold, is in at least two parts: the arched central part 10 arranged to be driven in rotation about the axis 12 of the bottom merged with the axis of the mold and of the container to be obtained, and a peripheral part 13 carrying the rotary central part 10.
- the peripheral part is driven by the only axial translational movement.
- the rotary drive of the vaulted central part 10 is carried out using a motor 14, such as an electric motor, fixed to the block constituting the peripheral part of the bottom 11 of the mold.
- the mold also comprises, in a known manner, in addition to the bottom 11 of the mold, two half-molds 15a., 15b. determining the final shape and dimensions of the body and the shoulder of the final container 5.
- FIGS. 4A to 4C illustrate a preferred embodiment of an installation for implementing the method of the invention.
- This embodiment uses, for driving the arched central part 10, a pneumatic motor 16.
- a pneumatic motor 16 The structure of such motors is known in various applications and will not be repeated in detail in the figures.
- Such an engine comprises a motor turbine driven by a fluid, such as air, under pressure, and the rotational movement of the turbine is transmitted to the central part 10 by means of gears or equivalent means, the production of which is within the reach of those skilled in the art.
- the pressurized fluid used for the rotation of the pneumatic motor 16 is for example compressed air which serves to drive a piston 17 with which the mold base 11 is integral to cause the longitudinal displacement of the latter and bring it into contact with the bottom of the blank 4.
- the bottom 11 of the mold is, in known manner, integral with the piston 17, which is movably associated with a chamber 18 formed in a base 19.
- This base 19 is itself mobile, along the longitudinal axis of the mold cavity between a high position and a low position. In the high position, the base 19 is clamped in the lower parts of the half-molds 15a., 15b., And completes the molding cavity. The low position allows the container to be removed from the mold.
- the jack thus constituted by the piston and the chamber is double-acting, and two conduits 20, 21, pass through the base to open out on either side of the chamber 18 of the piston 17.
- a first conduit 20 makes it possible to bring the bottom 11 of the mold into contact with the bottom of the blank; the second 21 makes it possible to spread the mold bottom, by lowering it.
- the bottom 11 of the mold is traversed by a conduit 22 which opens on the turbine on the one hand and which is in connection with the chamber 18 on the side where the conduit 20 opens for bring the fluid allowing the displacement of the jack 17 in the direction of the approximation between the mold base and the bottom of the blank.
- FIGS. 3A to 3C can use a structure similar to that of FIGS. 4A to 4C for the longitudinal bottom of the mold, except that it is not necessary to provide the conduit 22, since the motor is not pneumatic, but electric.
- FIGS. 3A to 3C also illustrate the case where the bottom 11 of the mold is not brought closer to the bottom of the blank 4 as soon as the mold is closed, but is gradually brought closer during the finishing blowing.
- the mold base is then reassembled.
- FIG. 3A illustrates the phase immediately following the closing of the finishing mold: the blank 4 is at the maximum length, and the bottom of the mold is in the low position.
- Figure 3B shows, exaggeratedly, the shape of the blank 4 after the start of blowing.
- FIG. 3C shows the finished container and the position which the bottom of the mold occupies at the end of this phase.
- FIGS. 4A to 4C is illustrated the case where the bottom 11 of the mold is brought into contact with the bottom of the blank 4 immediately after closing the mold.
- FIG. 4A the bottom 11 of the mold has not yet started to rise, but the central part 10 is in rotation.
- a pressurized fluid Ps is injected into the conduit 20. The ascent then begins and the bottom 11 of the mold comes to occupy the position illustrated in FIG. 4B.
- FIGS. 4A to 4C illustrate the case where the shape of the bottom of the blank does not completely correspond to that of the bottom of the final container 5, and FIG. 4B shows said container in its almost final shape except for the bottom which is not yet fully formed, FIG. 4C finally shows the completed container 5 and the relative position occupied by the container 5, and the various parts (walls 15a., 15b_, and bottom 11) of the mold.
