Abstract
Description
- The present invention relates to a module for the metering of pasty products, of the type comprising a tank for the pasty product, provided with pushing means for the pasty product and opening and closing means, adapted for opening and closing an outlet of aforementioned tank.
- The present invention also relates to a system for mixing pasty products which is based on previous modules, and a process for using the metering module and the aforementioned mixing system.
- The present invention is particularly, although not exclusively, for use in the metering and mixing of dyes in paint production.
- At present, the mixing of primary dyes used in the production of paint is mainly done manually, putting the previously measured amount of dye in a recipient. However, there are good number of automatic or semi-automatic metering systems in which the dye is poured from an upper tank onto a lower recipient with a loading cell which, once a predetermined weight of dye is captured, orders a valve on the higher tank to close and stop the pouring. This operation is repeated for each of the primary dyes until the mixture with the required proportions of each one has been made.
- Although these existing automatic or semi-automatic systems work effectively, they are not completely devoid of problems and inconveniences, especially as they are extremely complex and very expensive and the fact that, when the valve closes, a last drop is formed which can harm the precise metering, dirty the installation and hamper the next operation.
- The purpose of the present invention is to provide a system for metering pasty products, which offers an integral solution to all of these problems and inconveniences.
- To this end, the first aspect of the invention is a new module for metering pasty products, as mentioned above, which is basically characterized in that the tank is a hollow prism and the pushing means comprises a vertical-action piston which runs tight within the tank and coaxially with the same, the opening and closing means comprising a lower metering valve, the body of which contains an internal space for a vertical axle which opens into with the tank, the sealing element of the valve being a closing head, which is movable between a maximum open position and a closed position, on which the main base of the seal remains essentially level with the valve outlet, closing the tank.
- Said sealing element can be built in to an actuating rod which passes inside said internal cylindrical space of the valve body and which is also activated by a trip dog, counter to the action of a spring.
- Preferentially, said closing head is frustoconical and the tank is cylindrical.
- According to another characteristic of the invention herein, the module comprises a device for purging the air remaining trapped inside the tank below the piston.
- In accordance with a preferred embodiment, each module comprises a device for injecting air inside the tank, adapted so that the piston can be separated from the bottom of the tank or from the mass of pasty product in the tank.
- The metering module of the invention can comprise a mechanism for opening a container packaging the pasty product, once it is placed inside the tank.
- Preferably, said opening mechanism consists of a blade, whose cutting edge is situated on the side of a cylinder which circles, or at least partially circles, the outlet of aforementioned tank.
- A second aspect of the invention is a system for mixing pasty products, comprising at least one module as described above.
- More specifically, the system can comprise at least two of the earlier modules, placed consecutively adjacent to one another in a first horizontal plane with the corresponding and closely aligned metering valves, and a receive vessel displaceable ever a guide means, the vessel being adapted for positioning under each module and receiving a measured amount of the pasty product contained in the module for mixing the pasty products.
- Preferably, the mixing system shall comprise control means for controlling the movement of the receive vessel and the corresponding measuring of each metering module that must pour pasty products into the vessel, with certain predetermined mixing parameters.
- In particular, said control means comprises a microprocessor, a computer and/or a programmable logic controller, supplied with the relevant software, and a conventional interface with the user, which activate motor and timer means of the vessel and the metering valves of each of the metering modules.
- With respect to a third aspect of the invention, a process for metering pasty products is disclosed, for application in conjunction with a metering module or a mixing system defined earlier, which includes the stage of providing a pasty product in a container packaging with deformable wall, and additional steps of: inserting the closed packaging and filling the tank with the pasty product; making the piston to descend and compress the packaging, with its sides deforming against the inner walls of the tank; and opening the container packaging by opening means, making an opening in the packaging, aligned with the outlet, allowing the pasty product contained in the packaging to exit towards the metering valve, via the subsequent compression of the piston.
- Hereafter, a description will be given of a preferred, although not exclusive, embodiment of the invention herein, which is accompanied with drawings to help provide a better understanding, which are purely illustrative and non-limitative in rature, in which:
- Fig. 1 is a section view of a valve of the metering module of the invention herein;
- Fig. 2 is an elevation and part section view of a preferred embodiment of the metering module of the invention herein;
- Fig. 3 is a front-elevation schematic view of a system for mixing pasty products, comprising seven modules like those in Fig. 2;
- Fig. 4 is a side-elevation schematic view of the metering system in Fig. 3;
- Fig. 5 is a view similar to that in Fig. 2, of another embodiment of the invention modlue, with a packaging of the pasty product inserted in the tank, in the rest position; and
- Fig. 6 is a view similar to that in Fig. 5, but with the piston in its operational position.
-
- It can be seen in said drawings that the
metering module 1 concerned, for pasty products, for example, for dyes or paints, comprises a cylindrical tank2, and apiston 4, essentially discoidal, for pushing thepasty product 34 in thetank 2. Some O-rings 19 ensure that the piston is adjusted 4 on the inside of the tank. Thepiston 4 is moved vertically along anaxle 8, using a known method, via a built-in actuatingrod 24, and hydraulically or pneumatically operated. Thetank 2 sits on alower base 27, connected to anupper support base 28 and guided by theactuator 24 viacolumns 23. - The lower central part of the
tank 2 opens into anoutlet 3, through which a bushing tube passes 29, in the lower end of which is a manual cut-off key 25, followed by ametering valve 5, located on the inside of an end piece 30. - The
valve 5 has avalve body 6 with a space inside 7, whoseaxle 8 is, in this case, shown with thevertical axle 8 of thetank 2. This internal space 7 is open to thebushing 29 and, through this, to the inside of thetank 2. Thevalve 5 has a sealingelement 12 made up of aclosing head 9, which is preferably frustoconical in shape or in the form of a trumpet, although it may also be spherical. - The
head 9 can be moved continually between a maximum open position and a closed position (represented in Fig.1), in which themain base 11 of theseal 12 is essentially level with thevalve 5outlet 31, closing thetank 2. - The
sealing element 12 is built in to an actuating rod 13, which passes inside the aforementioned internal cylindrical space 7 of thevalve body 6 and which is activated by atrip dog 14, counter to the action of aspring 10. The rod 13, and consequently the opening and closing of thevalve 5, can therefore be operated mechanically or manually, in this case, for example, via the manual key 25. - Fig. 2 shows the
metering module 1 for pasty products in the invention with a device for purging the air, which remains trapped inside thetank 2 below thepiston 4. In the example embodiment given, such purging device comprises ahydraulic tube 20, connected to aflexible pipe 17 which passes through thepiston 4 and has amanual key 21. Thetube 20 is connected upstream from themanual key 21, with a relative vacuum source with respect to the internal pressure of thetank 2. - The
module 1 also has a mechanism for injecting air inside thetank 2, adapted so that thepiston 4 can be separated from the bottom of the tank or from the mass of pasty product in the tank. This injection mechanism also has anair injector 22 linked to anotherflexible pipe 18 which passes through thepiston 4, allowing air to enter inside thetank 2 when thepiston 4 is to beseparated and which may be trapped in thetank 2. - Figs. 3 and 4 show a system for mixing
pasty products 100 which hasvarious modules 1, in this case seven, described above. - The
modules 1 are placed consecutively and adjacently in a first horizontal plane with corresponding and essentially alignedmetering valves 5, fixed to thevertical element 32 of asupport structure 26. - The
support structure 26 comprises a horizontal table 33, on which there areguides 16 for areceiving vessel 15 for thepasty products 34 contained in themodules 1. - On the upper part of the
vessel 15 is a loading cell 35 (Fig. 4) and the vessel can be positioned under eachmodule 1 and receive a measured amount of the pasty product contained in the module for mixing the pasty products. - The
system 100 comprises a means of controlling the movement of the receive vessel and of the corresponding metering of pasty products of eachmetering module 1 that must be poured into thevessel 15, with certain predetermined mixing parameters. - Such control means can include a microprocessor, a computer and/or programmable logic controller, with the relevant software, and a conventional interface with the user which, being extensively known, are neither shown nor described in greater detail. The control devices activate a motor and timer of the vessel and the
metering valves 5 of each of themetering modules 1. - The operational mode of the system for mixing and metering
pasty products 100 is as follows. With thetanks 2 of themodules 1 completely or partially full of pasty product, thereceive vessel 15 is moved along theguides 16 and is positioned successively below each of themodules 1 whose product is to be used in the mixture required. Thevessel 15 can be moved manually or by a motor, in this case with stepped motors which is programmed when to move and stop. - Each time it is positioned below a
module 1, thecorresponding valve 5 opens via, for example, the manual key 25, with which the dye in thetank 2 in question starts to be poured, until theloading cell 35 detects that the quantity programmed or a quantity sufficiently close to the programmed quantity has been poured, which is when thevalve 5 closes and the pouring of the pasty product is stopped. The aforementioned software can take into account the weight of the column of dye remaining between thevalve 5outlet 31 and thevessel 15, to close at the appropriate time in order to add the weight in this column to that detected by theloading cell 35 and to programme the measured amount ofdye, within a certain tolerance. - This operation is constantly repeated for each of the
modules 1 containing dye used in the mixture. - In Figs. 5 and 6 an embodiment of the
module 1 of the invention herein is shown. Thismodule 1 is designed particularly to demonstrate the process of the invention in practice. - More specifically, the
module 1 comprises a mechanism for opening acontainer packaging 36 with deformable walls, which contains thepasty product 34 for metering, consisting of ablade 37, whosecutting edge 38 is situated on the side of a cylinder which circles at least partially theoutlet 3 of theaforementioned tank 2. Theblade 37 can be in the form of a half shaft, or half bevel, for example, not with its upper edge orblade 38 perpendicular with respect to theaxle 8. - The
packaging 36, which may be a bag, for example made of a plastic material, with or without seams, or cardboard packaging, contains a measured amount of the pasty product to be administered and is inserted inside thetank 2 of the module 1 (Fig. 1). Thepackaging 36 could therefore be a recipient made of cardboard or paper whose measurements allow it to fit within the inner prismatic walls of thetank 2. - Once the
packaging 36 is inside the tank, for metering thepasty product 34 via thevalve 5, all that needs to be done is lower thepiston 4, compressing thepackaging 36 by collapsing its sides against the inner walls of thetank 2. For the compressing force exerted by thepiston 4 to continue, thecontainer packaging 36 is opened by theblade 37, which cuts it, making aopening 39 in the packaging (Fig. 6), aligned line with theoutlet 3, to let out thepasty product 34 contained in thepackaging 36 towards themetering valve 5, by the subsequent compression of thepiston 4. - Once the container packaging is empty 36, all that needs to be done is raise the
piston 4, leaving the rest of thepackaging 36 empty, so that it can be removed. In this way, an exact and measured quantity of the paste material is administered, without staining thetank walls 2. - An expert skilled in the art will understand that the valve design and, in particular, the shape of the sealing
element 12, ensures that the metering of dye with this system produces no drops around theoutlet 31. It also significantly reduces wastage of the raw material and consequently the environmental problems related to managing the waste, compared to earlier techniques. - Furthermore, if the
packaging material 36 can be recycled, the process in the invention is efficient from an environmental point of view, by minimizing the amount of waste produced. - It must be understood that the invention device herein applies to all types of pasty products of similar rheology to that of paints and dyes, these applications also being within the scope of the invention design.
