DETAILED DESCRIPTION
[0040]
[0041] In the embodiment of
[0042] Each upper dispensing module 12′ is preferably provided with a cover 16 which affords access to the interior in order to fill or refill the tanks 34 of fluid product. However, the lower dispensing modules 12″ can be constructed to be removable with a frame structure which is fixed and a carriage or cartridge which is movable on rollers 14. The lower dispensing modules 12″ can thereby be removed from the machine 10 at least partially in order to access the tanks 34 and thereby to be able to fill them or refill them.
[0043] The front portion of each dispensing module 12 is preferably covered by a front panel 18 which may be completely or partially transparent or semi-transparent. In some cases, the front panel 18 may be able to be opened or removable, completely or partially, in order to afford access when necessary to the front portion of the dispensing module 12, where the fluid products are dispensed into the containers B. In the front portion of each dispensing module 12, there is provided a horizontal transport system for containers B which, in the embodiment of the Figure, is constructed by means of motorized roller conveyors 20. In particular, the motorized roller conveyors 20 comprise roller conveyor portions, each of which has an extent which is substantially equal to the front width of each dispensing module 12 so as to completely cover the entire extent in terms of width of the machine 10, at each of the two levels. Preferably, the roller conveyors 20 extend laterally at a side of the machine 10 in order to define the inlet E and the outlet U of the containers. Alternatively, the inlet E and/or the outlet U of the containers B can be formed by means of other transport systems, such as, for example, transporter belts or robot arms, or more simply by using inclined planes, on which the containers B can slide in order to be introduced into and discharged from the machine 10. Naturally, the transport system for the containers B may be of a type different from the roller conveyor 20 and may completely or partially comprise transporter belts or other systems of the type generally known.
[0044] At the side of the machine 10 opposite the inlet E and the outlet U of the containers B, there is provided a vertical transport system for the containers B from one level to another of the machine 10. In particular, in the embodiment of
[0045] In
[0046] In the machine 10, there can be produced formulations of lacquers in different quantities for containers B having different capacities. To this end, the containers B are received in respective adapters 27 which are carried by platforms in the form of slides 25. The adapters 27 allow the opening of containers B having a different height and width to be positioned at the same height and at the centre with respect to dispensing nozzles 21 for fluid products.
[0047] There is mounted on the machine 10 an electronic processor which regulates the general operation of the devices, including the control of the dispensing of the fluid products by one or more dispensing modules 12, by coordinating it with the transport of the containers B and the stoppage thereof at the dispensing module(s) from which the fluid products necessary for the specific formulation of lacquer desired are dispensed. Preferably, the functions of the machine 10 and the programming of the formulations, similarly to the calibration and maintenance operations, are carried out by interfacing as known with an operator by means of a screen 28 and a keyboard 30. The calibration can also be carried out individually and independently for each dispensing module 12. Naturally, the programming and the control and the interrogation of the state of the machine can be carried out by means of any other type of data-processing interface and system, for example, by means of a remote administration system, such as a remote server, a cluster of servers, a service or an application in the cloud, as well as a remote terminal which communicates with the machine, for example, a tablet, a smart phone, a computer or any other system of the generally known type.
[0048] With reference to
[0049] As can be seen in
[0050] A motor 36 is connected to the rotary table 33, for example, by means of the engagement of a pinion with a tooth arrangement 33′ which is formed on the periphery of the rotary table 33. In this manner, the rotary table 33 can be rotated selectively, preferably in both rotation directions, so as to carry the desired pumping group 35 into alignment with an operating dispensing zone 40 which is positioned at the front of the dispensing module 12. The roller conveyor 20 is preferably fixed to the support structure 31 and is controlled in known manner by a motor 41 which controls, for example, a system of pulleys and belts which are connected to the rollers of the roller conveyor 20. The roller conveyor 20 can transport and support a slide 25, on which the adapter 27 for a container B is mounted. As a result of the roller conveyor 20, the container B can be transported below the nozzle 21 into the operating dispensing zone 40, in which one or more fluid products which are contained in the tanks 34 can be dispensed inside the container B in accordance with the formulation of lacquer desired.
[0051] The pumping group 35 comprises a volumetric pump, for example, an alternating volumetric pump of the type described in the above-mentioned document WO2020/165822. The pump communicates with a respective tank of fluid product 34 through an intake pipe. The pumping group 35 also comprises a valve group. The pump communicates with the valve group which can be switched into different positions so as to dispense the fluid product which is pumped by the pump into a container which is positioned under it and which is supported on the roller conveyor 20. The valve group can be switched in order to carry out precise dispensing, with minimal quantities, for example, in order to obtain a sample of lacquer, or it can be switched in order to dispense greater quantities of fluid product, where necessary to produce a greater quantity of lacquer. The valve group can also be switched in order to carry out the recirculation of the fluid product by re-introducing it into the tank 34.
[0052] In the operating dispensing zone 40 there is mounted a motor group for actuating the pump of the pumping group 35 which is located in the operating dispensing zone 40 following the rotation of the rotary table 33. A valve actuator group is also mounted in the operating dispensing zone 40 in order to control the valve group of the pumping group 35 which is located in the operating dispensing zone 40 following the rotation of the rotary table 33.
[0053] The dispensing module 12 described above is particularly advantageous because it allows precise dispensing with a very high resolution. The dispensing nozzles always remain clean and the recirculation of the fluid product in the tank 34 is carried out until the last drop. The dispensing module 12 does not need periodic calibration. This results from the fact that the dye dispensing circuits are quite short, the pumping group is not substantially subjected to wear. The dispensing module 12 allows a high level of working flexibility, being able to dispense the same fluid product both in large quantities, with a high flow rate in order to reduce the dispensing times, and in extremely small quantities with great precision and resolution. These particular features of the dispensing module 12 allow a compact machine, having limited dimensions, but still capable of dispensing both into relatively large containers, for example, having the capacity of several litres, and into extremely small containers which are used for samplings, for example, of 100 cc. This constitutes a substantial advantage in the field of retouching operations and repairs for vehicles in the bodies because it is possible initially to produce different samples of formulations of lacquers and to test if it is the most appropriate shade for the retouching work, using in this step minimal quantities of fluid products. Subsequently, the high precision and repeatability of the dispensing modules, as a result inter alia of the volumetric rather than gravimetric dispensing of the fluid products, in addition to all the other technical characteristics set out above, allow the production of a lacquer according to the formulation desired, in the appropriate quantity, with a shade which is identical to the shade of the preselected sample without any need for subsequent corrections or waste of fluid product.
[0054] Another advantage of the dispensing module 12 is the possibility of completely recirculating the fluid products in the tanks 34 through a dedicated recirculation pipe, which is preferably connected to the tank with spacing from the intake pipe. In this manner, the complete recirculation of the fluid product is promoted, which promotes the elimination of air from the fluid product and prevents the drying out or the separation of the fluid product. The recirculation operation of the fluid products in the tanks 34 can be carried out at regular intervals, for example, in the recirculation downtimes of the dispensing module 12, so as to also keep the fluid products which are used less frequently, but which are nevertheless equally costly with respect to the products used more frequently, in a state mixed and ready for use.
[0055]
[0056] It is possible to arrange on the roller conveyor 20 a proximity sensor 46 which detects the presence of the slide 25, for example, in a central position, corresponding to the operating dispensing zone 40 for the correct centring of the opening of the container B under the dispensing nozzle. In the zone of the roller conveyor 20 corresponding to the operating dispensing zone 40, it is also possible to provide a weighing device which is formed, for example, by means of load cells which are associated with the rollers of the roller conveyor 20, in order to weigh the container B if it is necessary or desirable to control the fluid products being dispensed into the container B by weight.
[0057]
[0058] Each container B is provided with an identification code 48, for example, a bar code, QR code, an RFID tag or other identification code which is, for example, applied to the container B with an adhesive or printed or using another known system. The identification code 48 is associated with a corresponding formulation in the electronic processor. The identification code can be read when the container B is introduced into the machine 10 in order to carry out the correct dispensing of the fluid products necessary for the formation of the corresponding formulation.
[0059] Before the inlet into the first dispensing module 12, the identification code 48 of a container B is read so as to retrieve the relative formulation from the memory of the processor. The dimensions of the container B are then checked with the detection system with micro-switches described above. If the dimensions of the container B do not correspond to those associated with the identification code 48, there is generated a warning or an alarm and the container B does not continue into the machine 10. It is further possible to check whether there is a sufficient quantity in the machine 10, in the various tanks 34, of all the fluid products necessary for producing the formulation. If a predetermined fluid product is not present at sufficient quantities, there is generated a warning or an alarm and the container B does not continue into the machine 10. In fact, the quantities of fluid product present in each tank 34 are stored in the machine 10. The stored quantities are updated, in an increasing manner, after each filling or refilling operation of a tank 34. The quantities stored are further updated, in a decreasing manner, before each fluid product is dispensed so that the stored quantity is always precise or at most too low with respect to the real quantity if an interruption to the electrical energy occurs during the dispensing operation.
[0060] The containers B are transported along the upper level of the dispensing modules 12′, where they can where applicable be filled with one or more fluid products by being located below the operating dispensing zones 40′ of the upper level. From the upper level, the containers B are lowered by the lifter 22 to the lower level of the dispensing modules 12″, where they can where applicable be filled with one or more fluid products by being located below the respective operating dispensing zones 40″ of the lower level. The containers B are then raised by the lifter 23 in order to be transferred to the outlet U, where there is preferably arranged the outlet roller conveyor 20b, by which it is possible to remove the containers B with the finished lacquers in accordance with the various formulations which are programmed in the machine 10.
[0061] A particular feature of the machine 10 is the fact that a plurality of containers B can be moved simultaneously, each of which can be transported under a given dispensing module 12 for dispensing specific fluid products which are defined by the formulation of lacquer desired. This flexibility of transport of the containers B inside the machine 10, together with the distributed presence of the various fluid products in the various dispensing modules 12, allows a greater productivity than the known machines to be obtained, together with a more articulated automation which avoids the presence of an operator at the start and end of the preparation of each formulation of lacquer.
[0062]
[0063] In the preceding description, reference has been made by way of example to the machine of
[0064] Other systems for formulating lacquers also provide for one or more bases or resins which constitute approximately 50% of the total of the lacquer to be dispensed. In order to comply with these formulation requirements, one or more dispensing modules 12 can be configured so as to dispense a single base which is stored in a tank with large dimensions and which is received in the dispensing module 12 or, if necessary, which is positioned outside the machine 10. Preferably, the dispensing of the base or bases is carried out after the dyes have been dispensed inside the container B, which is initially empty. The one or more dispensing modules 12 which are dedicated to dispensing the bases are therefore arranged at the end of the path of the containers B, slightly before the outlet U of the machine.
[0065] The modularity of the machine also allows different requirements to be met, for example, where the space available is small, or if it is necessary to manage a smaller number (or also a larger number) of fluid products or to store greater quantities thereof, for example, for specific products with a wider use.
[0066] In relation to this last requirement, it is possible to dedicate more than one tank 34, in the same dispensing module or in different dispensing modules, to the same fluid product. This allows the production of a greater stored reserve of one or more fluid products with more frequent use, leaving, for example, only one tank dedicated to products with less frequent use. For example, if a fluid product is used in the majority of formulations, it could be stored in more than one dispensing module 12 so as to allow the simultaneous formulation of a plurality of lacquers having the same fluid product, and the simultaneous dispensing into a plurality of containers B which are arranged under different dispensing modules 12.
[0067] If it is necessary to use and manage a reduced number of fluid products, the machine can be configured as in the example of
[0068] If the number of fluid products to be stored and managed is even less, the machine can be configured as in the example of
[0069] In the example of
[0070] In the example of
[0071] What is set out above provides indications for a person skilled in the art for producing different configurations of machines from those illustrated, also using only one dispensing module 12, or by combining a given number thereof in various manners, on one or more levels, by providing vertical transport systems for transferring containers from one level to another, and horizontal inlet and outlet transport systems which are combined continuously with the transport systems of the containers on-board each module 12.
[0072] The modular configuration of the machine 10 does not exclude the fact that, in place of two or more dispensing modules, there can be introduced a special component having dimensions which are equal to a corresponding multiple of dispensing modules. For example, there may be provided a special dispensing module having a height and depth which are equal to one of the dispensing modules 12 and, for example, double the width. Such a special double dispensing module could, for example, receive a dispensing system which is supplied by large tanks in order to dispense in large quantities bases and resins in a formulation system which provides for them.
[0073] Naturally, the principle of the invention remaining the same, the forms of embodiment and details of construction may be varied widely with respect to those described and illustrated, without thereby departing from the scope of the present invention.
