Description

Description of the Industrial Invention entitled: “INSULATION PANEL FOR VEHICLES USED FOR THE TRANSPORT OF MATERIALS, PREFERABLY SUITABLE FOR THE TRANSPORT OF MATERIALS AT CONTROLLED TEMPERATURE, PROCEDURE FOR THE PRODUCTION OF THE SAID PANEL AND VEHICLE SUITABLE FOR TRANSPORT OF MATERIALS, PREFERABLY SUITABLE FOR THE TRANSPORT OF TEMPERATURE CONTROLLED MATERIALS EQUIPPED WITH SAID PANEL" On behalf of: M&S CONSULTING SA VAT: CHE-114.882.086 Address: c / o TALENTURE SA, Via Canova 9, 6900 Lugano – Switzerland (CH) Inventors: Francesco CODISPOTI of Italian nationality, Raffaele PALMA of Italian nationality *** The present invention relates to an insulating panel for vehicles suitable for the transport of materials in general, preferably for the transport of materials at room temperature controlled (e.g. food transport). The present invention also relates to a process for the production of insulating panels for vehicles used for the transport of materials in general, preferably for the transport of temperature-controlled materials (e.g. food transport). The present invention also relates to a vehicle suitable for transporting materials in general, preferably for the transport of temperature-controlled materials (e.g. food transport) equipped with said panel. Insulation panels for vehicles used for food transport are usually made in starting from a structural shell, made for example of one or more of the following materials: Polystyrene (PS), High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), Polymethylmethacrylate (PMMA), Polypropylene (PP), Polyvinylchloride (PVC), fiber made of glass embedded in a polymer resin. In the structural shell a foaming operation is performed, for example by polyurethane in liquid form, aimed at distributing the insulating material inside the panel. Once the hardening phase of the insulating material is complete, the panel can be applied to the inside wall of a vehicle (e.g. a van) for food transport, that is, a vehicle whose compartment is thermally insulated from the outside and is kept at temperature controlled by a thermostatic system. The Applicant observes that the materials with which the insulating panels are made, although allowing the panels themselves to perform their function properly thermal insulation, they do not provide structural characteristics that can support objects (e.g. shelves, strap loops, etc.) fixed to the panel itself by rivets or tiles. In fact, if one were to try to use dowels or rivets with a known type of panel, the insulating material present inside the structural shell would not provide a mechanical resistance such as to allow any stable constraint. This prevents, for example, from holding still – or at least limiting – the movements and oscillations of – packages, boxes, etc. placed inside the compartment during transport. In this context, the Applicant has set itself the objective of overcoming this problem, thus providing a technique that allows for a stable and reliable fixing of shelves, slots, etc. inside the compartment of a vehicle suitable for transporting food.

With reference to the attached figures, a panel has been indicated as 80 in total. insulator in accordance with the present invention. Panel 80 (figures 8a, 8b) comprises a structural shell 81, made of one or more of the following materials: Polystyrene (PS), High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), Polymethyl methacrylate (PMMA), Polypropylene (PP), Polyvinyl chloride (PVC) and similar. preferably, the structural shell 81 is made through a process of thermoforming, which will be described below. The structural shell 81 has a substantially concave shape. This substantially concave conformation is defined by a generically area planar, and from a lateral wall, which extends in a substantially orthogonal direction from the perimeter of the generally planar area. The substantially concave conformation defines a concave zone C1 and a zone convex C2. Panel 80 includes a thermally insulating filling 82. The filling 82 is made of a material comprising polyurethane. Preferably, the filling 82 is achieved by a foaming operation and molding, which will be described below. The filling 82 is made in the concave area C1 of the structural shell 81. Panel 80 includes a reinforcing insert 83. The reinforcing insert 83 is positioned between the structural shell 81 and the filling 82. The reinforcing insert 83 is positioned in the concave area C1 of the structural shell 81. In practical terms, the reinforcing insert 83 is held in place by the filling 82. In one embodiment, the structural shell 81 has a seat 84 for the positioning of the reinforcement insert 83. In one embodiment, the seat 84 may be made as a recess, substantially counter-shaped to the profile of the reinforcement insert 83. This recess protrudes into the convex region C2. In one embodiment, the seat 84 may be associated with one or more ribs 85, which follow respective sides of the seat 84 itself. For example, in figures 8a-8c, they are schematically represent an upper rib and a lower rib, suitable to mate with two corresponding sides of the reinforcement insert 83. In one embodiment, the seat 84 may have one or more protrusions 86, which can act as centering elements of the reinforcement insert 83 – which features respective portions shaped like these protrusions. Preferably, the reinforcing insert 83 is made of metallic material, e.g. aluminum. Preferably, the reinforcing insert 83 has a plate-like shape, for example example with a rectangular profile in a plan view. Figure 1 shows schematically a system that can be used for the construction of panel 80. Plant 1 (Figure 1) includes a thermoforming station 100. The thermoforming station 100, as will become clearer later, has the task of give the panels the desired shape. The thermoforming station 100 (figures 1, 4a-4b, 5a-5d, 6a-6b) comprises a member automated loading 110, configured to pick up a sheet material 2 from a loading position P1 and place that material 2 in an operating position P2. In more detail, a plurality of stacked slabs are initially positioned in the loading position P1. This operation can be carried out either manually or in an automated manner. The automated loading device 110, made in for example, a set of automated motorized suction cups, takes care of picking up and place the plates, one at a time, in the operating position P2, so that they can be subjected to the thermoforming operation. The material of plate 2 is a plastic material comprising one or more of: Polystyrene (PS), High Impact Polystyrene (HIPS), Acrylonitrile Butadiene Styrene (ABS), Polymethyl methacrylate (PMMA), Polypropylene (PP), Polyvinyl chloride (PVC) and similar. The thermoforming station 100 comprises a wall 101 substantially horizontal (figures 5a-5d, 6a-6b). Wall 101 has a through opening 102. In practical terms, wall 101 is made as a frame, in the internal part of which there is the opening 102. Wall 101 has an upper surface 101a and a lower surface 101b. On the upper surface 101a, around the opening 102, a sealing element is arranged estate 103. The sealing element 103 can be designed as a gasket, essentially continues around the perimeter of opening 102. The opening 102 has smaller dimensions than the sheet material 2. In other words, the opening 102 and the plate material 2 have mutual shapes and dimensions such that, when the material 2 is placed on the upper surface 101a of the wall 101, it completely closes the opening 102. The opening 102 and the sealing element 103 define the operating position P2 for the material 2 in plate. In particular, material 2 is in the operating position P2 when it is supported on the upper surface 101a, and in particular on the sealing element 103, so to completely cover the opening 102. Thanks to the adhesion between the material 2 and the element of sealing 103 (preferably obtained by means of suitable clamps, which tighten the material 2 on wall 101), the opening 102 is substantially sealed. Therefore, material 2 in operating position P2 creates a tight separation between a region of space R1 above material 2 (therefore facing the surface upper 101a of wall 101) and a region of space R2 below the material 2 (therefore facing the lower surface 101b of the wall 101). Preferably, the space region R2 beneath the material 2 is bounded by a structure 104 with airtight closure, associated with wall 101, schematically represented in figures 6a-6b. In one embodiment, the motorized mold 130 (which will be described later) is located within such structure 104. The thermoforming station 100 further comprises a heating member 120, made for example as a pair of heating walls 121, 122. For example, a heating wall 121 is placed at a higher altitude than the wall 101 (therefore with respect to the sheet material 2 in the operating position P2), and a heating wall 122 is positioned at a lower height than wall 101 (therefore of the material 2 in plate in operating position P2). Each heating wall 121, 122 is controllable between a distal position PD and a proximal position PP with respect to the operating position P2. In practice, each wall heating element 121, 122, through respective movement organs, is brought to the operating position P2 when a plate needs to be heated up to its softening temperature, for thermoforming. For example, heated walls 121, 122 are arranged horizontally, substantially parallel to the ground, and are moved horizontally, to be moved between the distal PD position and the proximal PP position. Figure 4a shows schematically, according to a simplified lateral view, the heating walls 121, 122 in the proximal position PP, when the sheet material 2 it rests on the wall 101, in the operating position P2; figure 4b shows in schematically, according to a simplified lateral view, the heating walls 121, 122 in the distal PD position, when there is no plate material in the position operational P2. Preferably, the lower heating wall 122 (together with the respective heating members movement) is contained within the structure 104; in particular, when located in the proximal position PP, the lower heating wall 122 is interposed between the motorized mold 130 (which at this time is not operational, and is located in the rest position schematically shown in figure 6a) and the horizontal wall 101 – that is, between the motorized mold 130 and the sheet material 2. When the wall lower heater 122 is in the distal PD position, it does not interfere with the vertical movement of the motorized mold 130, so that the latter can reach the operating position schematically shown in figure 6b. In one embodiment, the heating walls 121, 122 are composed of resistors quartz, mounted inside reflective dishes to increase the degree of radiation and to limit heat loss. Preferably, the heating walls 121, 122 are equipped with an infrared pyrometer, able to read the temperature of the plate in such a way as to allow the cycle to processing to proceed once the set temperature has been reached. The Applicant notes that the pyrometer allows for time to be saved during the start- up machine and to have the plates always formed at the same temperature. In one embodiment, the heating member 120 has distinct zones selectively heatable. More specifically, it is possible to adjust the power of each single resistor or single groups of resistors forming part of the heating walls 121, 122. For example, the power of each individual resistor of the upper heating wall 121, while the regulation of the wall resistances lower heater 122 can be performed made for couples. Advantageously, the use of an energy monitoring technique is foreseen, which allows you to reduce electricity consumption when the heating walls are in the distal PD position. The heating time can be between 1 min and 20 min, for example between 3 min and 5 min. Once the thermoforming temperature has been reached (for example between 120°C and 230 °C), the heating member 120, and in particular the heating walls 121, 122, is returned to the distal PD position. The thermoforming station 100 comprises a first pressure system 140, configured to operate at operating position P2 so that at least part of the thermoforming takes place under controlled pressure conditions. Preferably, the first pressure system 140 is configured to operate after the heating organ 120 softened the sheet material 2, in particular after that the heating member 120 itself has returned to the distal position PD. In further detail, the first pressure system 140 is configured to generate, in a first phase, a higher pressure in the space region R2 below the material with respect to the space region R1 above material 2. In particular, the first pressure system 140 is configured to blow air under pressure (with temperature of about 50-80 °C) in the R2 region, below the material 2. Due to the of the seal between the material 2 and the sealing element 103, such air flow does not pass in the upper region R1, and tends to swell the material 2. This prevents the softened plate material 2 from collapsing under its own weight. before the 130 mold arrives, and it also causes the material to slide in the lateral areas, ultimately obtaining panels of a more uniform thickness; as will be clearer subsequently, depending on the number of shapes present on the mould, a corresponding number of bulges from which respective panels will derive. Note that the first pressure system 140 operates, preferably, only in the region lower R2, while the upper region R1 remains at ambient pressure. As mentioned above, the thermoforming station 100 comprises a mold motorized 130 which, at this point in the process, is brought into position P2 operating mode to thermoform material 2 into a sheet. More specifically, the motorized mold 130 is configured to move, in a second phase, in contact and sealed against the lower surface 101b of the wall 101, facing at opening 102. The second phase is preferably subsequent to the first phase. The motorized mold 130, in addition to the respective movement organs to be able to bring into the positions foreseen by the process, is equipped with one or more forms, which define the profile to be given to material 2 during the thermoforming phase. In one embodiment, the motorized mold 130 may be equipped with a single shape; in this case, the material plate 2 which is in the operating position P2 will be used to make a single panel. In one embodiment, the motorized die 130 may be equipped with two or more shapes; in this case, the material plate 2 which is in the operating position P2 it will be used to create two or more panels. In the case of two or more shapes present on the motorized mold 130, it is expected that the thermoforming station 100 includes one or more separation bars. Such one or more separation bars are associated above the material 2 in plate in so that, under the action of the first pressure system 140, a number is formed of swellings equal to the number of shapes present on the motorized mold 130 – therefore equal to the number of panels that will have to be made with the material sheet 2 present in the operating position P2. The Applicant observes that, in these bulges, the material flows into the lateral areas. Advantageously, one of the shapes present (or the shape present) on the mold motorized 130 is shaped in such a way as to create, on the thermoformed panel that will derive, the seat 84 for the reinforcing insert 83. The shape of the motorized mold 130 it is shaped to match the profile of the seat 84 to be obtained. Preferably, around the perimeter of the motorized mold area 130 which carries the shape / shapes to be given to the material 2, a sealing element is provided, such as for example a gasket. The area that carries the shape / shapes has dimensions smaller than the opening 102, while the perimeter described by the sealing element of the motorized mold is wider of the opening 102; in this way, when the motorized mold 130, in the second phase, is brought into contact with the lower surface 101b of the wall 101, the shapes pass through the opening 102 so as to be in position to interact with the material 2, while the sealing element of the motorized mold 130 is in contact with the lower surface 101b of wall 101, creating a sealed support. In the second phase, the first pressure system 140 is deactivated. Advantageously, the thermoforming station 100 includes a second system pressure 141, associated with the motorized mold 130. The second pressure system 141 is configured to operate in the second phase, i.e. when the motorized mold 130 is in contact with the lower surface 101b of the wall 101. The second pressure system 141 is configured to create, in a space area internal, delimited by the material 2 and the motorized mold 130, a lower pressure with respect to an area of ​​space external to said internal area of ​​space. In practice, the sheet material 2 (supported tightly on the sealing element 103 present on the upper surface 101a of the wall 101) and the motorized mold 130 (sealed against the lower surface 101b of the wall 101) form a zone of internal space, delimited above by the swelling (or swellings) of the material 2 and below from the motorized mold 130. The shapes present on the motorized mold 130 are located within this internal space area. The external zone is essentially the one found above material 2 swollen, and is essentially at ambient pressure. Each of the shapes present on the motorized mold 130 is equipped with a plurality of through holes, arranged in a suitable way, connected to the second pressure system 141. The second system 141, through these through holes, creates a depression in the aforementioned internal space area, so that the previously softened plate material 2 and inflated, it adheres to the surface of the shapes. The material 2 then cools and hardens. To aid this process (of the duration, for example, 1 minute), a jet of air can also be used. We then proceed to a third phase, in which material 2 is removed from the mould motorized 130. For this purpose, the second pressure system 141 is expected to generate a flow of pressurized air directed by the motorized mold 130, and in particular by the shapes present on the same, towards the material 2, through the aforementioned through holes. In this way, the detachment of the thermoformed material 2 from the motorized mold is favored 130. Advantageously, the thermoforming station 100 is served by a unit of control (not shown) configured to: receive indicative input data of panels to be thermoformed; select, based on this input data, a set of parameters associated with the panels to be thermoformed; check the station thermoforming 100 depending on the selected parameter set. In light of the above, it can be noted that the thermoforming station 100 is configured to supply 3 thermoformed sheets at the output, from which the following are then obtained a set of thermoformed panels 4. With reference to figure 1, a first non-thermoformed plate 2 is inserted into the thermoforming station 100 which, by thermoforming the sheet 2, provides a thermoformed sheet 3. Preferably, the thermoformed sheet 3 is trimmed in a trimming station 200 and tipped and cleaned in a 300 tipping and cleaning station. The trimming operation can preferably be performed by a machine Five-axis CNC. In one embodiment, the table of such a CNC machine is formed by a grid 201; for example, the lattice 201 comprises a plurality of tubular elements 201, preferably in steel (figure 10). Ideally, the scrap resulting from the trimming operation should be cut into portions small enough to fall into the empty spaces 203 of the lattice 201, so as not to interfere with subsequent operations and so that it can then be removed. However, the waste is sometimes of significant size and, in order to be reduced to pieces small enough, it would require a time incompatible with the rest of the process, and in particular with the time required for the thermoforming operation performed with the thermoforming station 100. Therefore, it is advantageously envisaged that, between the thermoforming station 100 and the trimming station 200, a removal apparatus 230 is installed (diagrammed in figure 1), such as a treadmill, which has the task of transporting the whole scrap off the production line. In other words, once the operation is finished trimming, the scrap is moved to the removal device 230; the latter takes care of transporting the waste itself until it falls into special containers collection 240. The thermoformed sheet 3 is a single sheet, through which it is possible to create different panels. The thermoformed plate 3 having, for example, three panel shapes, It is directed into the trimming station 200 and is transformed into three panels 41, 42 and 43. The Applicant notes that, in the following, reference will be made to the formation of three panels starting from a thermoformed sheet; however, as mentioned, from each individual sheet It is also possible to obtain a different number of panels. What is described here in relation to the formation of three panels, the same applies in a similar way to the formation of a different number of panels. One of the thermoformed panels 41, 42, 43 constitutes the structural shell 81 of the aforementioned insulating panel 80. The set of panels 41, 42 and 43 forms a panel package or assembly 4 which is headed towards the tipping and cleaning station 300 where the panels are actually turned over and cleaned. Subsequently, the package of for example three panels 41, 42 and 43 is directed into the 400 storage bays in stock. At this point a new plate (not shown in figure 1) not thermoformed, having the same characteristics as plate 2, it is inserted into the thermoforming station 100 and following all the operations described above you can give a second package or together of panels 7, composed for example of panels 71, 72 and 73, which is directed into the bay 400 in storage in stock. In figure 1 the assembly of thermoformed panels 4 comprises at least a first panel thermoformed 41, a second thermoformed panel 42, and also a third panel thermoformed 43. It is reiterated that the number of panels that make up the assembly is established according to the dimensions of the panels themselves, but in this context we are talking about refers to assemblies composed of, for example, three panels. Preferably, as mentioned, downstream of the thermoforming station 100, a trimming station 200. The trimming station 200 comprises an automated cutting member 210, for separate the thermoformed panels 41, 42 and 43 from each other and / or trim the edges of said panels thermoformed 41,42 and 43. Please note that each thermoformed sheet can coincide with a thermoformed panel, or include a multiplicity of thermoformed panels. In the first case, the trimming station 200 will be responsible for trimming the edges; in the second case, the station of trimming 200 will also separate the various panels that are part of each thermoformed sheet. In one embodiment, the trimming station 200 may comprise a 220 chip extraction equipment. For example, a 5-axis CNC milling machine can be used for trimming. The waste material is collected automatically, for example by a conveyor belt. motorized placed under the area where the cutting / trimming operation is carried out, and recycled. In one embodiment, downstream of the trimming station 200, and more generally at downstream of the thermoforming station 100, as mentioned, a station is planned tipping and cleaning 300. From a practical point of view, at the end of the trimming performed in the trimming station 200, the thermoformed panels 41, 42 and 43 can, for example, be turned with the concave surface downwards (in the case of a positive mould in a thermoforming machine) and chips from the machining may still be present. It is therefore advisable to carry out a cleaning and tipping operation, to facilitate subsequent operations Storage and foaming. A pick-up system collects the thermoformed panels 41,42 and 43 from the trimming station 200 deposits it in a closed box. The thermoformed panels 41,42 and 43 are tipped with the help of a robotic arm equipped with grippers and / or suction cups. During handling, the cleaning organ 320 (made for example (like a suction system) removes residual chips from machining and the excess material. The tipping and cleaning station 300 includes a robotic organ 310 for perform a reversal of the thermoformed panels 41, 42 and 43; in practice, the panels Thermoformed pieces 41,42 and 43 are rotated 180° around a horizontal axis. Therefore, while at the end of the thermoforming operation the panels are found with concavity facing downwards, following the overturning carried out at station 300 they are found with the concavity facing upwards – an arrangement which then favours the subsequent foaming operation. In the case of negative molding, the panels they are already facing with the concavity upwards, in the tipping and blowing station the panels will only be blown and tilted to let the residual shavings fall before be returned to their original position without being overturned 180°. The 300 tipping and cleaning station is also advantageously equipped with a cleaning 320, for vacuuming waste material from the thermoformed panel assembly 4, and prevent such waste material (deriving from previous processes) from being able to interfere with the subsequent skimming operation. Preferably, the tipping and cleaning station 300 is interposed between the trimming station 200 and the foaming station 500 which will be described later. In one embodiment, the system 1 comprises one or more storage bays 400, interposed between the thermoforming station 100 and the foaming station 500. More in In particular, the storage bays 400 are placed between the tipping station and cleaning 300 and the foaming station 500. The 400 storage bays are equipped with 410 automated handling devices which allow each bay to move into position to accommodate the assembly of 4 thermoformed panels that a robotic arm picks up from the tipping station 300. The storage operation is useful because the foaming (which will be described in (followed) requires longer times than the operations of thermoforming / trimming / flipping. For this purpose, at the exit of the tipping and cleaning station 300 the assembly of thermoformed panels 4 are picked up by a pick-up system (for example, a pick-up system is a device that ideally moves in an axle system Cartesian X and Y with a horizontal and a vertical direction) which places it in the bay of storage 400 assigned; the bay is automatically brought into position by a rail translation system. This system also allows the bay to translate vertically also along the vertical axis. The bays preferably translate only horizontally, the mobile bridge on which the pick-up deposits the piece instead translates vertically to bring the panels to the height of the desired drawer. As mentioned above, plant 1 comprises a foaming station or zone 500. The foaming station or zone 500 is located downstream of the thermoforming station 100 and, more specifically, downstream of the storage bays 400. The foaming station 500 consists of one or more presses, for example three presses. Each of these presses comprises a lower platen 510, an intermediate platen 520 and a top plate 530. In Figures 2, 3a, 3b, 3c and 3d for convenience it is reported the operation of a single press. As will be clearer below, on the plates the moulds are housed, having the respective shapes, for the creation of the panels. Each of the plates 510, 520, 530 extends substantially in a plane horizontal. The intermediate plate 520 is shaped at the top to accommodate the panels thermoformed 41-42-43. The upper plate 530 is shaped below so as to form, in cooperation with the intermediate plate 520, a mold for thermoformed panels 41, 42, 43 after that the latter will have been subjected to the skimming operation. The lower plate 510 is shaped at the top to accommodate panels thermoformed 71, 72, 73. The intermediate plate 520 is shaped at the bottom so as to form, in cooperation with the lower plate 510, a mold for the thermoformed panels 71, 72, 73 after that the latter will have been subjected to the skimming operation. The foaming station 500 comprises a foaming member 540, configured to perform foaming on the thermoformed panels 41, 42, 43 housed in the plate intermediate 520, and on the thermoformed panels 71, 72, 73 housed in the lower plate 510. In this way, 41' thermoformed foamed panels are obtained respectively, 42', 43' and thermoformed foam panels 71', 72', 73'. With reference to the panel thermoformed which constitutes the structural shell 81 of the insulating panel 80, through the foaming operation is carried out by filling 82 insulation. In one embodiment, the foaming member 540 is composed of a double-head foaming machine. One of the foaming heads is moved in automated manner on a Cartesian manipulator, while the other has the possibility of be moved by an operator via a motorized trolley. The head moved by the Cartesian manipulator it is used for mould foaming open (better described below), while the second is used to print in closed (if necessary, for example in the case of so-called “panels sandwich"). Preferably, the skimming member 540 further comprises two or more tanks for contain the substances necessary for the formation of foam. For example, polyol and isocyanate are stored in special steel tanks. These tanks are thermoregulated; in fact, there is a resistance in the tank jacket which allows to heat a specific fluid in order to keep the reagents at a controlled temperature. From the tanks, the reagents are injected into a high-pressure dosing group, using specially designed recipes that are recalled when necessary. The reagents then pass in the high pressure mixing heads where they are mixed so that they can dispense the foam (e.g. polyurethane) onto the thermoformed panel assembly 4 and on the assembly of thermoformed panels 7. The 500 foaming station includes, for each press, movement organs 550, active on the lower plate 510 and on the intermediate plate 520. The bottom plate 510 is movable horizontally and vertically. The intermediate plate 520 is movable horizontally and vertically. The upper plate 530 is preferably fixed (for example mounted on a frame integral with the ground). In one embodiment, each plate 510, 520, 530 is made of steel solid perforated. Preferably, each plate 510, 520, 530 is heated with water, at a maximum temperature of approximately 70-80° C and a maximum pressure of approximately 10 bar. The water heating flows inside the plates through special channels created during the process of making the plates themselves. For horizontal movements, for example, trolleys are provided; for the vertical movement of the intermediate plate 520 and lower plate 510 is foreseen piston system. The foaming station 500 includes a control unit 560, configured to control the movement organs 550 to carry out various phases within the scope of the foaming operation. In greater detail, for each of the three presses, the plates 510, 520, 530 are located initially aligned vertically, as schematically shown in figure 2. The the area where the plates are located in this configuration is identified as the zone operational Z0. The intermediate plate 520 is moved from the operating area Z0 to a zone of load Z1, in which it receives thermoformed panels 41, 42, 43 (figure 3a). This movement is preferably rectilinear and horizontal. The intermediate plate 520, which at this point houses the thermoformed panels 41, 42, 43, is brought back to the operating zone Z0. During this movement, the control unit 540 foaming dispenses foam onto thermoformed panels 41, 42, 43. When the intermediate plate 520 reaches the operating zone Z0, the operation foam dispensing in the thermoformed panels 41, 42, 43 is finished, and they have been so obtained the thermoformed foamed panels 41', 42', 43'. The intermediate plate 520 is then moved vertically, so as to close on the top plate 530 (figure 3b). Note that figure 3b shows schematically the intermediate plate 520 in contact with the upper plate 530. As better explained subsequently, the intermediate plate 520 is closed on the upper plate 530 by vertical movement of the lower plate 510, i.e. following the construction of the configuration of figure 3d. In other words, the intermediate plate 520 preferably closes on the upper plate 530 when the intermediate plate 520 itself is coupled with the 510 bottom plate. As mentioned, the cooperation between the plate intermediate plate 520 and upper plate 530 form a mold for thermoformed panels foamed 41', 42', 43'. After a pre-set time, the intermediate plate 520 is moved away from the top plate 530 and the finished product can be removed. The lower plate 510 is moved from the operating area Z0 to the loading area Z1 (figure 3b). This movement is preferably rectilinear and horizontal. Preferably, this movement occurs while the intermediate plate 520 is returning from loading zone Z1 to operating zone Z0. In loading zone Z1, the thermoformed panels 71, 72, 73 are loaded onto the plate lower 510. The lower plate 510 is then brought back into the operating zone Z0 (figure 3c). During this movement, the foaming organ 540 performs the operation of foaming on thermoformed panels 71, 72, 73. As mentioned, in this way they were thus obtained the thermoformed foamed panels 71', 72', 73'. Once the lower plate 510 has returned to the operating zone Z0, the delivery of foam in thermoformed panels 71, 72, 73 is finished. The lower plate 510 can then be moved vertically upwards, up to to close on the intermediate plate 520 and form, as mentioned, a mould for the panels thermoformed foams 71', 72', 73' (figure 3d). After a pre-set time, the lower plate 510 is lowered and brought into the zone Z1 and the finished product can be unloaded. Preferably, the lower plate 510 is also adapted to push the intermediate plate 520 against the upper plate 530; in this way, with a single movement you they obtain the closure of the mold formed by the intermediate plate 520 and the plate upper 530 (for 41', 42', 43' foamed thermoformed panels), and the closure of the mold formed by the lower plate 510 and the intermediate plate 520 (for the panels thermoformed foams 71', 72', 73'). Note that the foaming operation takes place in an open mold; in other words, the foam is deposited over the entire surface of the thermoformed panel assembly 4 and of the thermoformed panel assembly 7 via a moving head fixed on a manipulator Cartesian. The Applicant notes that this solution allows for obtaining important advantages compared to state-of-the-art processes; the latter, in fact, typically They involve an injection of the foam from a single point in a closed mould, a technique with however the foam is unable to reach all areas of the body evenly artifact, both because of geometries that may present irregularities, and because as the polyurethane exits the injector head it begins to polymerize, increasing its viscosity and making it more difficult for it to travel towards the most vulnerable areas. far away. Otherwise, by injecting into an open mold, the foam is deposited in homogeneously over the entire affected area and during polymerization the direction of expansion is mainly in height. Advantageously, the foaming operation can be fully automated; the path, the quantity of foam to be deposited and the working parameters are pre- stored and recalled according to the specific operation to be performed. More specifically, the foaming organ 540 can be moved above the panels thermoformed to be foamed according to pre-set paths, in order to perform a foaming of such thermoformed panels. In one embodiment, preset paths are selected, for each panel or set of panels, depending on the input data associated with the panels on which perform the skimming. The input data can be entered by an operator, via a suitable interface user. In one embodiment (Figure 9), it is envisaged that the bottom plate 510 and / or the intermediate plate 520 can also be moved to an additional area Z2. The additional zone Z2 is preferably located on the opposite side of the operating zone Z0 compared to the load zone Z1. In other words, the load zone Z1 is preferably interposed between the operational zone Z0 and the further zone Z2. In the additional area Z2 it is possible that particular work is carried out on the panels, before or after the foaming operation. The additional zone Z2 can be used for positioning the reinforcement insert 83, in particular in the seat 84 obtained on the structural shell 81. The reinforcement insert 83 is positioned before the execution of the operation foaming, so that the reinforcing insert 83 itself remains interposed, in position, between the filling 83 and the structural shell 81. Using system 1 and the process carried out by it, it is possible to obtain panels insulators. Such panels can be conveniently used for vehicles suitable for the transport of temperature-controlled materials, such as food transport. For example, a 600 vehicle suitable for transporting materials preferably at room temperature controlled is schematized in figure 7. In a manner known per se, the vehicle 600, for example, may comprise a chassis 610, handling equipment 620 (engine, transmission, wheels, etc.) associated with chassis 610 and a 630 compartment mounted on the 610 frame itself. Compartment 630 is configured to contain the materials / objects to be transported (e.g. general goods (food) at controlled temperature. For this purpose, vehicle 600 also includes a refrigeration system, associated with compartment 630; or, compartment 630 could be, for example, part of the 610 frame. The refrigeration system is configured to maintain the 630 compartment at a temperature controlled. The compartment 630 is delimited by one or more walls 631; one or more of these walls may comprise or be formed by respective insulating panels 80, made as described above. In particular, an insulating panel 80 can be fixed, in a manner known per se, to a of the walls 631, so that the concave area C1 (filled by foaming) is overlooking and in contact with wall 631 itself. Advantageously, one or more fastening elements 87 are provided (figure 8c), coupled to the insulating panel 80, in correspondence with the reinforcing insert 83. Fasteners 87 can be screws, dowels, rivets, etc. The fasteners 87 are installed so as to pass through the structural shell 81 and intercept the reinforcing element 83. In this way, it is possible to mount on the insulation panel 80, reliably, at least one of: a support element (e.g. a shelf), an anchoring element (e.g. a loop or hook for attaching straps), a thermal regulation device (e.g. a refrigeration apparatus). The object installed by means of the fasteners 87 is schematically indicated in figure 8c with the numerical reference 88. The invention achieves important advantages. First of all, the insulating panels made in accordance with the present invention allow the stable and reliable fixing of shelves, slots, etc. inside the compartment a vehicle suitable for transporting food. Furthermore, the panels are manufactured in a precise, accurate and repeatable way, thanks to to the automation of most of the operations performed. Another advantage is that, by virtue of the technical solutions covered of the invention, it is possible to work multiple sheets / panels in a substantially simultaneously, significantly increasing production efficiency. Furthermore, the open-mold foaming allows for controlled distribution. and homogeneous foam, thus obtaining panels with homogeneous properties along the entire their extension. An additional advantage is that the materials used are entirely recyclable, with obvious positive effects from the point of view of production costs and of the environmental impact.
