    [0001] BACKGROUND OF THE INVENTION The invention relates to a method for controlling a hollow body conveyor through a heating station for a heating station and a conveyor. an installation for manufacturing containers made of thermoplastic material, comprising: a heating tunnel defining a heating path; a conveyor comprising at least one running rail forming a circuit, and shuttles able to circulate along the rail by embedding at least one hollow body, each shuttle being controlled in displacement individually, the rail having a heating section for transporting hollow bodies along the heating path; an input device for the hollow bodies to be heated, bringing the hollow bodies to a loading section of the running rail for their loading on the shuttles, two successive shuttles flowing with a first determined entry gap on this loading section; ; an output device for hot hollow bodies which recovers the hollow bodies on board the shuttles running on an unloading section of the traveling rail. TECHNICAL BACKGROUND OF THE INVENTION The manufacture of thermoplastic containers, such as bottles, flasks, etc. is generally carried out from preforms, sometimes called blanks, which are introduced into a molding device with which are associated 3035651 2 forming means, for example blow molding or stretch-blow molding. In the rest of the description and in the claims, the preforms and the finished containers will be referred to as the generic term "hollow body". Traditionally in this technical field, the preform and the finished container have an identical neck or neck. As a result, the same support member of a preform by its neck is also adapted to support a finished container.
    [0002] The container manufacturing plant is fed with preforms which are not able to be formed directly due to their insufficient temperature. Prior to blow-molding or stretch-blow molding, the preforms are heated in a heating station so as to provide them with a sufficiently malleable structure for the blowing operation. Such large-scale manufacturing facilities for containers are equipped with a heating station comprising a heating tunnel provided with means for heating the preforms. This heating tunnel determines a heating path along which the preforms are generally transported by a conveyor at high speed without stopping. The tunnel has a length sufficient to allow the heating of the preforms during their crossing.
    [0003] The conveyor comprises individual preform support members which run along a closed circuit, a portion of which conveys the preforms along the heating path which passes through the heating tunnel. The support members are generally formed by mandrels which are capable of driving the preform transported in rotation about its axis to ensure a homogeneous heating of the preform. Furthermore, the preforms are fed one after the other by an input device to an input zone 3035651 3 in the heating station. The input device is generally formed by a rotating wheel equipped at its periphery with preform support members, such as notches or clamps. The preforms are thus loaded onto the conveyor at the entry zone in which the trajectory of the conveyor support members is tangent to the path of the preform support members of the input device. To allow preforms to be transferred from the input device to the conveyor, the conveyor support members must flow in a coordinated manner, both in position and speed, with the support members of the input device in the conveyor. entrance area. On the input wheel, the preforms are spaced by a determined pitch according to their direction of movement. Therefore, it is imperative that the individual support members of the conveyor are spaced apart by a gap equal to the entry step of the preforms as they pass over the entry area. The same problem is encountered for the transfer of the hot preforms, at the exit of the heating path, to an output device similar to the input device. In addition, the heating station has a particularly long and bulky heating tunnel. It would therefore be interesting to be able to achieve a shorter heating tunnel, and therefore more compact, without deteriorating the heating quality of the preforms. In addition, in the known heating stations of the state of the art, the preforms moving in the heating tunnel are separated from each other by a relatively large step. As a result, a large part of the heating radiation emitted by the heating means is produced in pure loss because it passes into the space left between two preforms without heating the latter. Thus, a large amount of energy is wasted.
    [0004] According to another problem, the hot preforms are intended to supply at least one subsequent treatment station, in particular the forming station. It frequently happens that the pitch between two successive preforms in the next processing station is different from the pitch between two successive preforms transported by the input device. As a result, a transfer device capable of changing the pitch between two preforms is generally interposed in the stream of preforms downstream of the furnace and upstream of said next processing station. Such a transfer device with change of pitch is not only expensive, but it also has the disadvantage of increasing the size of the forming installation.
    [0005] BRIEF SUMMARY OF THE INVENTION The invention relates to a method for controlling a conveyor of the type described above, characterized in that two successive shuttles traveling on this unloading section are spaced apart by a determined exit gap which is different from the first entry gap. According to other characteristics of the process: at least from their entry on the heating section, the shuttles are controlled so that the spacing between two successive shuttles is reduced compared to said first entry gap; - The distance between two shuttles remains reduced compared to said first input gap as they circulate on the heating section; Spacing between two successive shuttles remains equal to a second constant spacing as long as they run on the heating section; The third exit gap is different from the first entry gap; the outlet gap is greater than the second heating gap.
    [0006] The invention also relates to a conveyor for carrying out the method according to the invention, characterized in that each shuttle comprises a first support member of a first hollow body and a second support member of a second hollow body, the shuttle being thus capable of simultaneously carrying two hollow bodies, the support members being movably mounted on the shuttle between an extended position in which the support members are spaced apart from said first inlet gap in the direction of movement of the the shuttle, and a compacted position in which the support members 15 are brought closer to each other in the direction of movement of the shuttle. According to other features of the conveyor: the shuttle comprises an arm defining an orientation axis, each end of said arm comprising one of the support members, said arm being rotatably mounted relative to the shuttle around a main axis between a straight position corresponding to the direction of movement of the shuttle, and an inclined position inclined relative to the straight position; the conveyor comprises an actuator which is able to control the arm between its upright position and its oblique position; the actuator can be actuated by an actuating member carried by one of the adjacent shuttles.

    [0007] DETAILED DESCRIPTION OF THE FIGURES In the remainder of the description, elements having identical structure or similar functions will be designated by the same references.
    [0008] In the remainder of the description, a longitudinal direction, directed from back to front according to the direction of movement of the preforms, will be adopted in a nonlimiting manner, a vertical direction directed from below upwards orthogonally to the plane of displacement of the preforms. , and a transverse direction that is perpendicular to the two previous directions. FIG. 1 shows a part of an installation 10 for manufacturing in large series containers of thermoplastic material such as polyethylene terephthalate or PET. The manufacturing installation 10 is here intended to form containers from preforms 12 to be heated. The manufacturing facility 10 comprises a station 14 for heating the preforms 12 and a station 16 for forming, here by blowing or stretch-blow molding, preforms 12 previously heated by said heating station 14. The heating station 14 comprises a heating tunnel 18, which is here produced in three successive sections. The heating tunnel 18 has been shown schematically.
    [0009] The heating tunnel 18 defines a heating path which is intended to be traversed by each preform 12. Conventionally, such a heating tunnel 18 is delimited by two side walls (not shown) which form a tunnel. At least one of the walls is provided with heating means (not shown) emitting radiations heating the preforms, such as infrared lamps. The heating tunnel 18 can also be equipped with ventilation means making it possible to favor a homogeneous heating of the preforms and making it possible to avoid overheating of certain components of the heating station 14. The heating station 14 also comprises a conveyor 20 which is intended to transport each preform 12 through the heating tunnel 18. In normal operation of the manufacturing installation 10, the conveyor 20 is here intended to transport the preforms 12 in a continuous manner, that is to say without interruption of the displacement of the preforms 12. The length of the heating tunnel 18 and the power of the heating means is adapted so that the preforms 12 are heated to a temperature sufficient for their forming by the forming station 16. The conveyor 20 comprises at least one running rail 22 which forms a closed circuit. Shuttles 24 are 5 likely to circulate along the rail 22 scroll. Each shuttle 24 is individually controlled in displacement, that is to say independently of the other shuttles 24. As a variant not shown of the invention, the transverse rail the heating station according to an open circuit, the rail 10 also serving treatment stations upstream or downstream. Such an arrangement is referred to as "sequential". Shuttle 24 and scroll rail 22 are part of a linear motor. In such an engine, the traveling rail 22 comprises a stator which is formed of a series of coils (not shown) which are distributed along the rail 22. Each winding is individually controlled to locally induce a magnetic field independently. other windings. The coils are for example controlled by an electronic control unit (not shown) which is suitably programmed. Each shuttle 24 is equipped with at least one permanent magnet which reacts with the magnetic field induced by each winding of the rail 22 by causing the shuttle 24 to move along the rail 22. Moreover, each shuttle 24 is guided in displacement on the along the scroll rail 22. The pitch between two windings is sufficiently small to enable the windings of the scrolling rail 22 to be controlled so as to cause the displacement of each shuttle 24 independently of the other shuttles 24.
    [0010] Such a linear motor is for example sold by Beckhoff under the name "XTS". For further details concerning this technology, reference may be made to the documents US-A1-2013 / 0.119.897, US-A1-2013 / 0.035.784, WO-A1-2013 / 143.783 or WO-A1- 2013/143 950. In general, this technology implemented in the context of the invention makes it possible to move all the shuttles 24 in a queue in the same direction of movement along the circuit, here a counterclockwise direction. The speed of movement of each shuttle 24 can be controlled individually by an electronic control unit (not shown).
    [0011] Each shuttle 24 comprises at least one individual support member of a preform 12. In the embodiment of the invention shown in FIGS. 1 to 4, each shuttle 24 comprises a single individual support member of a preform 12. In the example shown in Figures 2 to 4, it is a mandrel 26 which is inserted vertically into a neck of the preform 12. Thus, each shuttle 24 is able to transport a preform 12. The mandrel 26 is for example, mounted vertically sliding on the shuttle 24 between a low position preform gripping and a high ejection position of the preform. The sliding is for example controlled by an electric motor or by a cam system. The scroll rail 22 can be divided into several sections.
    [0012] At least one section known as the "heating section 22B" of the traveling rail 22 allows the shuttles 24 to transport the preforms 12 along the heating path. The heating section 22B extends from an inlet 28 of the heating tunnel 18 to an outlet 30 of the heating tunnel 18.
    [0013] A section called "loading section 22A" of the sliding rail 22 is arranged upstream of the inlet 28 of the heating tunnel 18, according to the direction of circulation of the shuttles 24. The preforms 12 to be heated are loaded onto the shuttles 24 3035651 10 circulating on this section 22A. Thus, the shuttles 24 arrive on this section 22A loading "empty" and they come out loaded with a preform 12 to heat. A section called "unloading section 22C" of the sliding rail 22 is interposed between the outlet 30 of the heating tunnel 18 and the loading section 22A, in the direction of circulation of the shuttles 24. The hot preforms 12 are discharged for shuttles 24 traveling on this section 22C unloading. Thus, the shuttles 24 arrive on this section 10 22C unloading loaded with a hot preform 12 after passing through the tunnel 18 heating and they come out "empty". The manufacturing installation 10 also comprises a device 32 for entering the preforms 12 to be heated causing the preforms 12 to be heated up to the section 22A for loading the rail 22 for loading on the shuttles 24. The device 32 of FIG. The inlet is capable of bringing each preform 12 successively to the loading section 22A, two successive preforms 12 being separated by a determined entry step in their direction of movement. In the example shown in Figure 1, the input device 32 is formed by a wheel 34 with notches 36. The wheel 34 is rotatably mounted about a vertical axis. The wheel 34 has at its periphery notches 36, each of which is capable of carrying a preform 12. Two neighboring notches 36 are circumferentially spaced from said determined input pitch. In the embodiment shown in FIG. 1, the installation 10 also comprises a device 38 for outputting the hot preforms 12 which is capable of transferring the preforms 30 from the unloading portion 22C of the sliding rail 22 to the forming station 16. The output device 38 is designed to take the preforms 12 one after the other 3035651 11, two successive preforms 12 spaced apart by a determined output step in their direction of travel. In the example shown in FIG. 1, the output device 38 is formed by a wheel 40 equipped at its periphery with a plurality of arms 42. Each arm 42 comprises at its free end a support member such as a clamp 44 able to grasp a preform 12 by its neck. The forming station 16 is here formed by a carousel 46 (only part of which is shown) which carries a plurality of molding units 48 at its periphery. The carousel 46 is rotatably mounted to move the preforms 12 during forming. Such a forming station is well known and will therefore not be described in more detail later. Generally, the circumferential gap between two neighboring molding units 48 is greater than the determined output step of the hot preforms 12. In this regard, the arms 44 are generally pivotally mounted and / or sliding on the wheel 40 to allow changing the pitch between two successive preforms 12 during their transport to the station 16 forming. Thus, the preforms 12 are separated by a step adapted to the spacing between two molding units 48 during their transfer to the forming station 16. We now describe a method of controlling the conveyor 20 to take full advantage of the energy used by the heating means of the heating tunnel 18. In this embodiment, the spacing between two shuttles 24 is equal to the longitudinal spacing between the two support members 26 of each of the two shuttles 24. As shown in FIG. 2, when they are traveling on the section 22A loading of the rail 22 scroll, two shuttles 24 successive flow with a first spacing "El" input determined. This first gap "El" corresponds to the determined entry step of the preforms 12 to be heated. Thus, each shuttle 24 passes in coincidence with a notch 36 of the input device 32 for inserting the mandrel 26 into the neck of the preform 12 while the latter is still supported by the notch 36.
    [0014] Then, at least from their entry on the heating section 22B, the shuttles 24 are controlled so that the spacing between two successive shuttles is reduced relative to said first spacing "El" input. The spacing between two successive shuttles 24 remains reduced compared to said first 10 "El" input gap as they circulate on the heating section 22B, that is to say at least until they exit the tunnel 18 heating. This has the effect of reducing the pitch between two preforms 12 during their heating. Thus, a greater proportion of the radiation emitted by the heating means is usefully absorbed by the preforms 12 for their heating. In addition, this makes it possible to simultaneously circulate a larger quantity of preforms in the heating tunnel 18.
    [0015] In the embodiment shown in FIG. 3, the spacing between two successive shuttles 24 remains equal to a constant second spacing "E2", referred to as the heating gap, as long as they run on the heating section 22B of the rail 22. scrolling.
    [0016] Then, when the shuttles 24 arrive on the unloading section 22C, they are controlled in such a way that two successive shuttles 24 travel with a determined third distance "E3", as shown in FIG. 4. This third spacing "E3" is determined so as to minimize the change of pitch between two successive preforms 12 during their transport by the output device 38. Each shuttle 24 is more particularly controlled so as to circulate in coincidence with a corresponding support member 44 of the output device 38 to allow the transfer of preform 12 between the conveyor 20 and the output device 32. As a variant not shown of the invention, the gap 5 between two successive shuttles flowing over the heating section is likely to vary, while remaining lower than the inlet gap. Such variation of the spacing makes it possible in particular to control more precisely the heating profile of the preforms, particularly when certain portions of the body 10 of the preforms must be heated in a preferential manner. According to the embodiment shown in Figures 2 and 4, the third spacing "E3" output is different from the first spacing "El" input, here the third spacing "E3" output is greater than the first spacing "El" d 'Entrance. Therefore, the third outlet gap "E3" is also greater than the second heater gap "E2". In general, the second spacing "E2" of heating is advantageously less than the first spacing "El" input and the third spacing "E3" output.
    [0017] FIG. 5 shows a variant of this first embodiment in which the third spacing "E3" between the shuttles 24 traveling on the unloading section 22C coincides with the pitch between two molding units 48 of the station 16 of FIG. forming. In this case, it is no longer necessary to arrange an output device 32 capable of modifying the pitch between the preforms 12 since the preforms are already discarded from the pitch adapted to the forming station 16. As shown in FIG. 5, the preforms 12 are here directly transferred from the conveyor 20 to the forming station 16 without the interposition of intermediate transport means between the heating station 14 and the forming station 16. Thus, the hot preforms 12 are directly deposited in the molding units by the shuttles 24.
    [0018] This arrangement makes it possible to produce a very compact manufacturing installation. It also makes it possible to reduce the transfer time between the heating of the preforms and their forming. There is shown in Figure 6 a second embodiment of the manufacturing facility 10. This installation 10 is similar to that described in the first embodiment shown in Figure 1. Only the differences with this first embodiment will therefore be described later. In this second embodiment, each shuttle 24 10 comprises a first member 26A for supporting a first preform 12 and a second member 26B for supporting a second preform 12. The shuttle 24 is thus able to simultaneously carry two preforms 12 Each support member 26A, 26B is for example formed by a mandrel.
    [0019] The support members 26A, 26B being movably mounted on the shuttle 24 between an extended position in which the support members 26A, 26B are spaced apart from the first entry step of the preforms in the direction of movement of the shuttle 24, and a compacted position in which the support members 26A, 26B are brought closer to each other in the direction of movement of the shuttle 24. For this purpose, the shuttle 24 comprises an arm 50 defining an axis of orientation. Each end of said arm 50 has one of the support members 26A, 26B.
    [0020] The arm 50 is itself pivotally mounted on the shuttle 24 about a vertical main axis between a straight position corresponding to the direction of movement of the shuttle 24, and an inclined position inclined relative to the straight position. The pivoting of the arm 50 between its two positions is for example 30 controlled by an actuator (not shown) on board the shuttle 24. During operation of the conveyor 20, the shuttles 24 traveling on the section 22A loading the rail 22 of 3035651 15 scroll are controlled to be spaced apart from a first spacing "El" which is equal to twice the determined entry step of the preforms 12. In addition, the arm 50 is controlled in its upright position. Thus, all the support members 26A, 26B, in their extended position, are spaced at the same pitch as the entry pitch of the preforms 12. When the shuttles 24 are traveling on the heating section 22B of the rail 22 for scrolling, the arms 50 are controlled to their oblique position. This allows the shuttles 24 to be controlled so as to be spaced apart by a second gap "E2" which is much smaller than the first gap "El". The shuttles 24 are read particularly controlled so that the preforms 12 are distributed in two rows, as shown in FIG. 6. The preforms 12 of the first row are carried by the transport members 26A arranged in front of the shuttles 24 while the preforms 12 of the second row are carried by the transport members 26B arranged behind the shuttles 24. In addition, in an oblique position, the arm 50 forms an angle 20 with the direction of movement of the shuttles 24 , for example an angle of 45 °, so that the preforms 12 of the first row are offset longitudinally between two preforms 12 of the second row. In this position and with this spacing "E2" between the shuttle 24, the support members 26A, 26B occupy their compacted position. This particularly compact arrangement makes it possible to simultaneously circulate a large quantity of preforms 12 in the heating tunnel 18 while allowing all the preforms 12, whatever their rank, to be exposed to the same amount of heating radiation as the Other preforms 12. In this second embodiment, the entry step of the preforms is equal to the exit step of the preforms. Thus, when they run on the discharge section 22C, the shuttles 24 are controlled to be spaced apart from said first gap "El" which is equal to twice the determined entrance pitch of the preforms 12. In addition, the arm 50 is controlled in its right position. Thus, all the support members 26A, 26B, in their extended position, are spaced at the same pitch as the exit pitch of the preforms 12. The actuator is for example an autonomous actuator, such as a motor, which is embedded on the associated shuttle.
    [0021] In a variant not shown of the invention, the actuator requires an external intervention to be actuated. This is for example a cam control device. A cam follower is for example embedded on the shuttle, while a cam path arranged parallel to the circulation rail 15 makes it possible to act on the cam follower to actuate the arm. In variant not shown of the invention, the actuator can be actuated by an actuating member carried by one of the adjacent shuttles. Thus, when the spacing between two shuttles 24 is decreased, a pusher of a shuttle 24 is able to come into contact with a pivoting mechanism of an adjacent shuttle 24 to control the pivoting of the arm 50. It is for example a cam device or a meshing device. The control method carried out according to the teachings of the invention thus makes it possible to circulate a larger number of preforms in the heating tunnel, independently of the entry step and the exit step of the preforms. Of course, the method is not limited to the embodiment shown in the figures. For example, a preform processing station and / or final containers may be interposed between the furnace outlet and the unloading section. Such an arrangement is particularly advantageous in a "sequential" arrangement of the processing stations, as previously explained. In this case, the conveyor makes it possible to convey a hollow body from its initial state in the form of a preform, then, after the forming of said preform, in its final state of finished container.
    [0022] In addition, the control method also makes it possible to modulate the spacing between two shuttles so as to space the preforms of a first entry step on the loading section 22A, of a second heating step on the section 22B. and a third exit step on the discharge section 22C. These three steps may be different from each other.
