SYSTEM FOR COOLING OBJECTS

Description

DESCRIPTION

[0001] The present invention regards a system for cooling objects of various types exiting from heating furnaces.

[0002] The system is especially suitable to be used in lines for obtaining the superficial zinc-flake coating of products and/or objects, where provided for upon exit from drying furnaces that form such lines.

[0003] As known, the superficial zinc-flake coating treatment for objects is obtained in production lines that provide for different operating steps comprising, among others, impregnation and heat treatment operations with heating cycles in a furnace and subsequent cooling.

[0004] During the aforementioned operations, the objects are contained in special baskets that enable transferring them from one machine to the other.

[0005] Furthermore, upon exit from the heating furnaces the objects contained in the baskets are transferred into special containers with greater capacity where they are cooled using air which is conveyed into the containers through the upper opening thereof.

[0006] This method of operating reveals a first drawback which lies in waste of time and thus the increase of production costs due to the need to transfer the objects from the baskets to the containers.

[0007] Furthermore, though efficient, the cooling carried out according to the aforementioned method reveals, however, the drawback lying in the fact that the in-flowing air which is blown into the containers through the upper opening thereof generates a counter-current flow of the out-flowing air, overheated by the contact with the components to be cooled, thus slowing the cooling process.

[0008] Last but not least, a drawback lies in the fact that such counter-current flow complicates the collection of the overheated air coming from the containers and loaded with pollutant substances deriving from the residues of the products used in the operations that stick against the objects.

[0009] Patent documents FR 2 917 752 and DE 10 2009 048797 describe systems for the heat treatment of objects that provide for a ventilation system which generates a cooling airflow in a process chamber which is arranged in fixed position.

[0010] Above all, such systems reveal the drawback lying in the fact that they are of the static type and the containers of the objects to be treated remain fixed in position over the entire period of time during which the cooling of the objects that they contain occurs.

[0011] Such systems also have a low cooling efficiency.

[0012] The aim of the present invention is to overcome the aforementioned drawbacks.

[0013] In particular, one of the objects of the invention is to provide a system for cooling objects, products and components which, with respect to the prior art, enables accelerating the cooling times considering the same type and number of objects, products and components to be cooled.

[0014] Another object of the invention is to provide a system for cooling objects, products and components which, with respect to the prior art, facilitates the collection of the air loaded with possible pollutant substances which, after cooling the objects, exits overheated from the containers in which the objects are contained.

[0015] Another object of the invention lies in the fact that the cooling of the objects is carried out using the same baskets that are used for holding the objects during the other operating steps.

[0016] Another object of the invention is to simplify and automate the operations for transferring the objects to be cooled.

[0017] Last but not least, another object of the invention is to provide for a better quality of drying.

[0018] The aforementioned objects are attained by a system for cooling products and/or components according to the main claim to which reference will be made.

[0019] The dependent claims describe other characteristics of the system of the invention.

[0020] The aforementioned objects and any other objects will be outlined in detail in the description that follows, which regards a preferred but non-exclusive embodiment of the invention and which is provided by way of non-limiting example with reference to the attached drawings, wherein:

• figure 1 represents the system of the invention in axonometric view;
• figure 2 represents a lateral view of the system of figure 1;
• figure 3 represents the section of the system of figure 2 carried out according to the section plane III - III;
• figure 4 represents another lateral view of the system of figure 1;
• figure 5 represents the section of the system of figure 4 carried out according to the section plane V - V;
• figure 6 represents the plan view of the system of figure 1;
• figures 7 and 8 represent the system of figure 1 in two bottom axonometric views.

[0021] The system for cooling subject of the invention, in figures 1 to 8 that represent it, is indicated in its entirety with 1.

[0022] According to the invention, and in particular with reference to figures 1 to 5, it is observed that the system comprises a fixed scaffolding 2 to which there is associated a moveable structure 3 which comprises a lower base 6 abutting against the fixed scaffolding 2, an upper base 7 spaced from the lower base 6 and by a lateral surface 8 which perimetrically delimits the lower base 6 and the upper base 7.

[0023] In this manner, the moveable structure 3 takes a substantially box and parallelepiped shape, inside which there is defined a ventilation chamber 5.

[0024] It is clear that in different embodiments the moveable structure 3 may take a different configuration with respect to the parallelepiped-shaped configuration described above and represented in the figures.

[0025] On the upper base 7 there are arranged a plurality of baskets 10 containing the objects to be cooled and the lower base 6 is provided with wheels 4 which rest against the tracks 15 of the fixed scaffolding 2.

[0026] Furthermore, the lower base 6 also supports a drive unit 16 which places the aforementioned wheels 4 in rotation to displace the moveable structure 3 with the baskets 10 along the tracks 15.

[0027] In particular, as observable in figures 2 and from 6 to 8, the lower base 6 is provided with four wheels 4 each arranged at a corner thereof.

[0028] Only two of the aforementioned wheels 4, as observable especially in figure 6, are driven by means of the aforementioned drive unit 16 which comprises a gearmotor 17 associated to a transmission shaft 18 which mutually connects the aforementioned two wheels 4, each resting against a respective track 15. In particular as regards the arrangement of the baskets 10 on the upper base 7 which receives them, according to the configuration described herein and represented in the figures, there are six baskets 10 and they are arranged aligned with respect to each other in two rows adjacent to each other and identifying an alignment direction Y wherein each row is made up of three baskets 10.

[0029] It is clear that the number and arrangement of the baskets represented in the drawings is purely by way of example, given that such number and such arrangement could be of any type depending on the needs of the user.

[0030] By means of the drive unit 16 the entire moveable structure 3 with the baskets 10 associated thereto can thus be displaced along the displacement direction X, orthogonal to the alignment direction Y of the baskets 10, in both directions indicated by the arrows in figure 6.

[0031] Each basket 10 is provided with a mouth 10a for loading the objects to be cooled and with a bottom 11 provided with a plurality of through holes 12.

[0032] In the upper base 7 there are provided ventilation nozzles 9 communicating with the ventilation chamber 5, which convey air to the through holes 12, obtained in the bottoms 11 of the baskets 10 resting against the upper base 7. To this end, as observable in figures 3, 5 and 6, on the upper base 7 there are provided a plurality of housings 19 which are configured so that each receives a respective basket 10 with the through holes 12 of the bottom 11 positioned so as to communicate with the ventilation nozzles 9.

[0033] Also provided are ventilation means 13 which are connected to the ventilation chamber 5 for conveying - thereinto - cooling air which, as previously mentioned, through the ventilation nozzles 9 and through holes 12, flows into the baskets 10 to cool the objects contained therein.

[0034] As regards the ventilation means 13, it should be observed that they comprise a fan 20 and a motor 21 both of which are supported by a framework 22 which, as observable in particular in figures 7 and 8, is positioned in the fixed scaffolding 2 and it is fixed beneath the lower base 6.

[0035] In particular, figure 2 shows that the frame 22 is spaced from the support surface of the system and thus the fan 20, the motor 21 and the framework 22 are stably hung on the lower base 6 and the fan 20 has the suctioning mouth 23 connected to a suctioning duct 24.

[0036] The latter, with particular reference to figure 5, comprises a first tubular section 24a which is fixed to the suctioning mouth 23 and a second tubular section 24b which is fixed to a fixed support 29 where the first tubular section 24a and the second tubular section 24b are coupled to each other by means of a telescopic tubular section 30.

[0037] The presence of the telescopic tubular section 30 enables maintaining the connection of the suctioning duct 24 with the suctioning mouth 23 of the fan 20 when the actuation of the drive unit 16 displaces the moveable structure 3, alongside the fan 20 and the respective motor 21 fixed to the lower base 6, in both ways of the displacement direction X.

[0038] With particular reference to figures 2, 3 and 5, it should also be observed that the delivery mouth 25 of the fan 20 is connected to a delivery hole 28 obtained on the lower base 6 and communicating with the ventilation chamber 5.

[0039] Substantially, the embodiment of the ventilation means 13 now described and particularly the presence of the telescopic tubular section 30 enable suctioning cooling air from the environment in which the system is located and conveying it into the ventilation chamber 5 and from the latter into the baskets 10 by means of the ventilation nozzles 9 and the through holes 12 present on the bottom 11 of the baskets 10, regardless of the position that the moveable structure 3 takes with respect to the displacement direction X.

[0040] The air that cools the objects contained in the baskets 10 then flows out through the mouth 10a thereof dragging along any pollutant substances constituted by the residues of the products of the previous treatments that were left stuck on the objects.

[0041] This air is overheated and loaded with pollutant substances which - if released into the environment - could cause serious pollution in the environment in which the system for cooling is installed.

[0042] To this end, there are provided suctioning means, generally indicated with 31, which enable collecting the air flowing out from the mouths 10a of the baskets 10 and conveying it to a possible treatment plant or, alternatively, discharging it in an environment outside the working zone where the system for cooling is installed.

[0043] The suctioning means 31, in the embodiment described herein, comprise a pair of suctioning ducts 32 arranged adjacent to each other extending according to the same alignment direction Y of the baskets 10, orthogonal to the displacement direction X of the moveable structure 3.

[0044] Each suctioning duct 32 is arranged above the baskets 10 and it is displaced laterally with respect to the centre of the mouth 10a of each one of them, for example as observable in figures 2 and 5.

[0045] Both suctioning ducts 32 are connected to the inlet path 33 of a fan 34 and each suctioning duct 32 is provided with lateral suctioning slots 35 arranged at the mouth 10a of a corresponding basket 10.

[0046] It is clear that the number and arrangement of the suctioning ducts 32 may vary as a function of the number and arrangement of the baskets 10.

[0047] Furthermore, as observable in the figures, the distance D between the suctioning ducts 32 is greater than the transversal dimension of the baskets 10, particularly than the diameter thereof in the case described herein, wherein the baskets 10 are cylindrical-shaped so as to enable loading/unloading them onto/from the upper base 7.

[0048] The operations for loading/unloading the baskets 10 may be carried out manually but preferably, especially considering the fact that their weight may be considerable, the system for cooling 1 also comprises a unit for displacing the baskets 10 indicated in its entirety with 40.

[0049] It should be observed that the displacement unit 40 comprises a gripper 41 for grasping the baskets 10 one at a time and it is supported by a fixed structure 43 configured to enable the movement of the displacement unit 40 according to the horizontal direction Y1, parallel to the alignment direction Y of the baskets 10, in both directions indicated by the arrows.

[0050] The displacement unit 40 in turn carries out the movement of the grasping gripper 41 according to the vertical direction Z, orthogonal to the upper base 7 for supporting the baskets 10, in both directions indicated by the arrows. Substantially, this enables obtaining a Cartesian movement of the gripper 41 for grasping the baskets 10 according to a plane orthogonal to the upper base 7 for supporting the baskets 10 and comprising the horizontal Y1 and vertical Z directions.

[0051] Thus, by combining the movement of the moveable structure 3 generated by the drive unit 16 according to the displacement direction X with the movement of the grasping gripper 41 generated by the displacement unit 40 according to the horizontal Y1 and vertical Z directions, the gripper 41 can deposit and pick up any basket 10 into and from any housing 19 present on the upper base 7. Operatively, by actuating the displacement unit 40 with the gripper 41 combined with the drive unit 16 which displaces the moveable structure 3, the baskets 10 can be loaded on the upper base 7 of the moveable structure 3 so as to be subjected to the cooling treatment which, as previously mentioned, occurs by insufflating air into the ventilation chamber 5 through the ventilation means 13.

[0052] Simultaneously, the suctioning slots 35 of the suctioning ducts 32 shut off the overheated and polluted air flowing out from the mouths 10a of the baskets 10 and move it away avoiding polluting the environment.

[0053] At the end of the cooling treatment, by activating the displacement unit 40 with the gripper 41 once again and displacing the moveable structure 3, the baskets containing the objects - cooled by now - can be unloaded so that the system returns to the initial conditions so as to be able to repeat a new cooling cycle.

[0054] Obviously, all these operations can be easily managed by control means that operate according to dedicated programmes and this enables improving the cooling process making it qualitatively repeatable and safer given that it enables reducing the direct action of the operators.

[0055] Thus, in the light of the above, it is clear that the system for cooling subject of the invention attains all pre-set objects.

[0056] First and foremost, as mentioned above, the system of the invention enables improving the cooling process making it qualitatively repeatable and safer. Furthermore, the possibility of simultaneously cooling a high number of baskets enables, with respect to the prior art, increasing the production of cooled objects.

[0057] Besides this, the possibility of shutting off the overheated air loaded with possible pollutant substances at the outflow mouths of the baskets avoids creating pollution in the work environment.

[0058] Furthermore, the system of the invention improves the cooling of the objects given that it prevents the formation of the counter-current airflows that are instead generated when cooling objects according to the prior art by blowing air into the containers through the loading mouth.

[0059] It has also been observed that the objects are cooled in the baskets that are used during other operating steps, thus eliminating inoperative times required - in the prior art - to transfer them into the containers in which they are cooled.

[0060] It has also been observed that the system of the invention can be managed by control means which operate based on dedicated programmes so as to make all operations aimed at cooling the objects safer, comprising the operations for loading and unloading the baskets.

[0061] It is important to observe that the system of the invention, which is particularly suitable for obtaining the cooling of heat-treated objects, can also be advantageously used for drying any objects that could be wet at the end of the treatments to which they were subjected.

[0062] In the implementation step, the system for cooling outlined in the current description may be subjected to modifications and variant embodiments aimed at improving the functionality thereof or making the manufacturing thereof easier and more economic.

[0063] However, it shall be understood that should such variants and modifications, that have not been described and represented in the drawings, fall within the scope of protection of the claims that follow, they shall all be deemed to fall within the scope of protection of the present patent.
