Definitions
- nozzles each comprise a relevant electronically-controllable shutter, which is adapted to open/close a relevant enamel exit opening.
- US 2003/230647 describes an equipment comprising an internally hollow load-bearing body inside which is housed to measure a roller in turn provided with an internal cavity meant to receive the enamel to be dispensed.
- the load-bearing body is provided with a plurality of orifices for dispensing the enamel on the outside and the roller is in turn provided with a plurality of holes adapted to allow the transit of the enamel contained inside the roller itself towards the outside following their alignment with the above-mentioned orifices.
- the roller is also provided with a relevant protrusion adapted to close the orifices during its rotation around the relevant axis and pushed towards the internal wall of the load-bearing body by relevant elastic means.
- US 2003/23064 does not allow uniform enameling of the relevant manufactured article to be decorated, inasmuch as, due to the presence and proximity of the holes and of the protrusions defined on the relevant roller, it involves the dispensing of a plurality of lines on the manufactured article itself. Such lines are then visible on the manufactured article and give it an irregular appearance.
- the equipment covered by patent document US 2003/23064 also has the drawback that the orifices can become blocked during normal operation, compromising the correct exit of the enamel.
- Patent document DE 4416747 describes an equipment for the enameling of manufactured articles comprising a hollow body, adapted to contain the enamel to be dispensed and provided with a plurality of orifices, inside which a cylinder is housed in turn provided with a series of cavities, so that when such cavities reach the orifices the enamel comes out towards the outside.
- WO 2017/209926 A1 discloses a coating apparatus for direct coatings with various shape comprising an internally hollow container comprising a dispensing zone defined on a lateral side and inside which a roller is housed, the roller being operable in rotation around a relevant axis for opening and close the orifices defined on the dispensing zone.
- the main aim of the present invention is to provide a piece of equipment which allows overcoming the drawbacks of the aforementioned prior art.
- one object of the present invention is to make a piece of equipment that allows managing the amplitude, the frequency and the position of the quantity of dispensed enamel in an easy and flexible way.
- Another object of the present invention is to provide a piece of equipment which is simple to make and operate.
- Not the least object of the equipment forming the subject of the present invention is to avoid the deposit and consolidation of the enamel and, at the same time, to prevent the orifices becoming blocked.
- Yet another object is to provide a piece of equipment which does not require the use of suction systems for the disposal of the enamel particles which remain in the air after its application.
- the equipment 1 comprises an internally hollow container 2 for the collection of enamel to be applied on a manufactured article M, which is provided with at least one group of through orifices for the outflow of the enamel.
- the container 2 is under pressure, e.g. between 0.5 bar and 3 bar. More specifically, the container 2 has one or more channels 12 for feeding the enamel inside it. By closing the orifices, it is also possible to make the enamel re-circulate inside the container 2 through the channels 12, the minimum number of which in this case must be two.
- the group of orifices defined on the container 2 is identified with the reference number 3, while the individual orifices are identified with the reference number 13.
- the container 2 is meant to be supported by a load-bearing frame 20 and the equipment 1 comprises movement means 10 for moving the manufactured article M to be enameled along a direction of forward movement V.
- the movement means 10 define a supporting surface of the manufactured article M placed below the orifices 13, and are composed e.g. of a plurality of motor-driven belts.
- the container 2, of the hollow type may have a cylindrical shape, in which case the group 3 of orifices 13 is preferably defined along its side wall, or it may have a box shape, in which case the group 3 of orifices 13 is defined on the wall delimiting the bottom of the container itself.
- the container 2 has a box-shaped on the outside and internally has a circular section.
- the orifices 13 are defined at the portion of the side wall of the container 2 arranged, in use, downwards.
- the container 2 therefore has a relevant axis, corresponding to its internal axis.
- At least one roller 4 operable in rotation around a relevant axis, identified in the figures by X.
- the volume interposed between the inner walls of the container 2 and the roller 4 defines a containment chamber 8 of the enamel.
- the section of the containment chamber 8 is decreasing towards the orifices 13.
- the volume of the containment chamber 8 decreases moving downwards. This means that the enamel is collected at the lower section area of the containment chamber 8, near the orifices 13, thus facilitating its exit following the opening of the orifices themselves.
- the orifices 13 have a portion which extends towards the inside of the containment chamber 8, and this results in a discontinuity with respect to the wall which delimits the containment chamber itself or with respect to the inner side wall of the container 2.
- the roller 4 is provided with at least one set of protrusions adapted to open and close the orifices 13 during the rotation of the roller itself, so as to allow and prevent respectively the enamel from flowing out of the container 2.
- the set of protrusions defined on the roller 4 is identified with reference numeral 5, while the individual protrusions are identified with reference numeral 15.
- the protrusions 15 then slide on the top of the orifices 13, obstructing the access mouth thereof.
- the trajectory covered by the protrusions 15 is therefore substantially tangential to the top of the orifices 13.
- the protrusions 15 "sweep" the access mouth of the orifices 13 removing any lumps of enamel that could be deposited on the mouth and creating an effect of mixing of the enamel which prevents the sedimentation thereof.
- the roller 4 is opportunely made of elastomeric material, in order to allow the deformation of the protrusions 15 following the interaction with the orifices 13 and, thereby, ensuring the closure thereof.
- the equipment 1 comprises adjustment means for adjusting the position of the axis X of the roller 4 with respect to the container 2.
- the adjustment means therefore allow modifying the position of the axis X with respect to the axis Y of the container 2, e.g. so as to compensate for any closing inaccuracies due to the wear of the parts.
- the adjustment means can be of the mechanical type, e.g. by means of register screws or other solutions known to the person skilled in the art, or, alternatively, of the electronic type.
- the orifices 13 can be closed either simultaneously, so that the internal volume of the container 2 is isolated from the outside and no enamel can come out, or sequentially, so that the orifices 13 are closed according to a predefined sequence during the rotation of the roller 4.
- each protrusion 15 is adapted to overlap a relevant orifice 13, obstructing it, when the set 5 of protrusions 15 reaches the group 3 of orifices 13.
- each orifice 13 corresponds a relevant protrusion 15, so that there is therefore an instant when all the orifices 13 are closed by a relevant protrusion 15.
- the duration of the time interval wherein the orifices 13 remain closed depends on the rotation speed of the roller 4 and on the relevant sizes of the orifices and the protrusions themselves.
- the protrusions 15 are bigger than the orifices 13.
- the protrusions 15 can, e.g., have a parallelepiped section and the orifices 13 a circular section, although conformations of different types cannot be ruled out.
- the roller 4 has a plurality of recesses 11 defining the protrusions 15.
- the protrusions 15 are therefore defined by a series of recesses 11 obtained on the roller 4 and their external surface corresponds to the external surface of the roller itself, so they do not exceed its external diameter.
- the recesses 11 allow the transit of the enamel towards the orifices 13 during the rotation of the roller 4. More in detail, during the rotation of the roller 4, the enamel is pushed through the recesses 11 by the pressure.
- the orifices 13 are therefore opened and closed as a result of the transit over these of the recesses 11 and of the protrusions 15, respectively.
- the amplitude of the recesses 11, and therefore of the protrusions 15, determines the opening time of the orifices 13, the rotation speed of the roller 4 being equal.
- the first direction 6 is substantially parallel to the axis X of rotation of the roller 4. In the embodiment shown in the illustrations, the first direction 6 is arranged transversely to the direction of forward movement V of the manufactured article M.
- the group 3 of orifices 13 and the set 5 of protrusions 15 comprise a plurality of rows 23 and a plurality of series 25 respectively, (two in this specific case, but embodiments cannot be ruled out wherein a greater number of rows 23 and series 25 is provided), where the number of series 25 is at least equal to the number of rows 23 and where the protrusions 15 of each series 25 are aligned along the first direction 6 with the orifices 13 of at least one relevant row 23, so that the protrusions 15 overlap to the orifices 13 when the set 5 of protrusions 15 reaches the group 3 of orifices 13.
- the number of series 25 of the protrusions 15 is equal to the number of the rows 23 of orifices 13, e.g., two rows 23 and two series 25, or that the number of series 25 is greater than that of the rows 23, e.g., two rows 23 and three or four series 25, in order to increase the closing frequency of the orifices 13.
- the number of series 25 or the number of sets 5 increases, so does the number of times the orifices 13 are closed with each turn of the roller 4.
- the closing time of the orifices 13 depends on their size and on the relevant protrusions 15, as well as on the rotation speed of the roller 4, the number of series 25 or of sets 5, as well as the rotation speed of the roller 4, affects the closing frequency of the orifices 13, i.e., the number of times the orifices 13 are closed in the unit of time.
- the dispensing areas of the enamel coming out of each row 23 of orifices 13 are staggered with respect to those of the adjacent rows 23, thus allowing more uniform enameling and a better coverage of the spaces compared to the case in which the dispensing areas obtained from the adjacent rows 23 are aligned with each other.
- the distance between the adjacent rows 23 (and therefore the amplitude of the angle ⁇ ) defines the distance between the dispensing areas on the manufactured article M to be enameled along the second direction 7, while the rotation speed of the roller 4 and the sizes of the orifices 13 and of the protrusions 15, define instead the time in which the orifices 13 remain closed.
- Figure 13 shows, schematically and by way of example, the distribution of the enameled areas on a manufactured article M.
- the enamel applied is of the punctiform type and the enameled areas recover the distribution of the orifices 13 defined on the container 2.
- the parameters such as the rotation speed of the roller 4, the sizes of the orifices 13 and of the protrusions 15 and the forward movement speed of the manufactured article M, the quantity of enamel dispensed at each opening of the orifices 13 can be changed, as can the reciprocal distance of the points where the enamel is applied, so as to obtain uniform enameling both as regards the quantity of enamel dispensed on the surface of the manufactured article M and its distribution.
- the roller 4 comprises a plurality of sets of protrusions 15 angularly spaced apart from one another along the circular extension of the roller itself.
- the angular distance between each set 5 of protrusions 15 also affects the closing frequency of the orifices 13. More in particular, the smaller the angular distance between a set 5 of protrusions 15 and the next set, the greater the closing frequency of the orifices 13, the rotation speed of the roller 4 being equal. In other words, the smaller the angular distance between one set 5 of protrusions 15 and the next set, the shorter the time that elapses between two successive closures of the orifices 13, the rotation speed of the roller 4 being equal, i.e., the shorter their opening time.
- the orifices 13 are therefore opened and closed in a sequential and cyclic way, i.e., with a determinate frequency, following the transit of each set 5 of protrusions 15 at the group 3 of orifices 13 defined on the container 2.
- the container 2 comprises a single row 23 of orifices 13 and a plurality of series 25 of protrusions 15 equally spaced the one from the other over the entire extension of the external surface of the roller 4.
- This specific arrangement of the orifices 13 and of the protrusions 15 makes it possible to apply a high number of enamel points on the manufactured article M and with a high frequency.
- the Figures 11 and 12 identify the closing and opening positions of the orifices 13 respectively.
- the equipment 1 comprises motor means 14 adapted to operate the roller 4 in rotation around the axis X. More in detail, such motor means 14 comprise electronic control means for controlling the rotation of the roller 4 around the axis X.
- the equipment 1 also comprises a command and control unit 9 adapted to command the start and movement of the motor means 14. More in particular, the equipment 1 comprises sensor means 16, e.g. of the type of a photocell, operationally connected to the command and control unit 9 and adapted to detect the position of the manufactured article M to be enameled in relation to the orifices 13.
- the command and control unit 9 is also operationally connected to the movement means 10 and is programmed so as to control the rotation of the roller 4 according to the position of the manufactured article M with respect to the orifices 13 and to its forward movement speed V so as to vary the quantity and/or frequency of the enamel dispensed through the orifices themselves.
- the command and control unit 9 is configured to command the rotation of the roller 4 following the detection of the transit of the manufactured article M to be enameled and to interrupt it once such transit has been completed.
- the command and control unit 9 is therefore programmed to operate the roller 4 in rotation, thus allowing the enamel to be dispensed only when the manufactured article M passes below the orifices 13, thereby avoiding any waste of material.
- the command and control unit 9 commands the interruption of enamel dispensing, blocking the rotation of the roller 4. More specifically, the command and control unit 9 stops the roller 4 in a position wherein the protrusions 15 block the orifices 13 to prevent the transit of the enamel.
- the command and control unit 9 is configured to adjust the rotation speed of the roller 4 according to the forward movement speed of the manufactured article M and to the type of application to be obtained.
- the quantity of enamel dispensed at each opening of the orifices 13 is reduced, i.e. the size is reduced of the relevant point applied on the manufactured article M, and at the same time the dispensing frequency is increased, i.e. the distance between two consecutive dispensing operations along the direction of forward movement V is reduced, so that the dispensed enamel points are closer to one another.
- the equipment 1 with the most suitable dimensions is chosen or the closing means are adjusted in order to regulate the extension of the rows 23 of orifices 13 responsible for dispensing the enamel.
- the container 2 is then fed with enamel at a substantially constant pressure, equal to about 1 bar, which is collected inside the containment chamber 8.
- the rotation of the roller 4 is then synchronized by the command and control unit 9 with the forward movement of the manufactured article M to be enameled, so that the dispensing of the enamel through the orifices 13 starts when the manufactured article M reaches the orifices themselves and stops once it has passed them.
- the command and control unit 9 also acts on the means of control of the rotation of the roller 4 to adjust its rotation speed, according to the forward movement speed of the manufactured article M, in such a way as to vary the quantity of dispensed enamel at each opening of the orifices 13 and the dispensing frequency, i.e. the distance between two successive dispensing operations along the direction of forward movement V.
- the rotation speed of the roller 4 corresponds to the forward movement speed of the manufactured article M to be enameled.
- command and control unit 9 can intervene on the movement means 10 to vary the forward movement speed of the manufactured article M, the rotation speed of the roller 4 being equal.
- the orifices 13 are then closed by the protrusions 15 by effect of the rotation of the roller 4.
- the protrusions 15 interact with the top of the orifices 13, closing their access mouth facing inside the containment chamber 8.
- the rotation of the roller 4 conveys the sets 5 of protrusions to the group 3 of orifices 13 and, as soon as the protrusions 15 of each series 25 overlap the orifices 13 of the corresponding rows 23, the container 2 is without openings towards the outside so that the enamel does not come out.
- the misalignment of the roller with respect to the container allows defining a chamber for the collection of enamel outside the roller itself and having a conformation such as to allow the collection of the enamel at the orifices, thus facilitating the exit thereof.
- the shape of the orifices, protruding towards the inside of the containment chamber ensures their correct and effective closure by the protrusions defined on the roller.
- the equipment thus conceived allows the enamel to be applied in a punctiform manner on the manufactured article M to be enameled, so as to obtain, as a result of the natural expansion of the enamel thus dispensed on the relevant surface, a uniform enameling free of aesthetic defects.
- the equipment according to the invention does not therefore have any construction or manufacturing limits and is able to adapt easily to any production requirement.
- the particular shape of the orifices, protruding towards the inside of the enamel containment chamber, and the closure "by rubbing" due to the tangential contact of the protrusions with the mouth of the orifices themselves, allows removing any residues or lumps of enamel that may deposit at this point.
- the rotary movement of the roller therefore makes it possible to keep the orifices free of any bodies that could obstruct the transit of the enamel.
- the shape of the containment chamber and the movement of the roller inside it allow the continuous mixing of the enamel, thus preventing this from depositing on the bottom and producing areas of different densities.
