Description

Method and device for dosing and positioning of pasty product

The present invention relates to a method for applying at least one strip of a pasty product, in particular a binder, to a support, in particular a wall in construction, according to which a pasty product is supplied with a container comprising an open face and a face. the bottom face being opposed to the bottom face, said bottom face being provided with at least a first opening which extends over at least a first part of the length of this bottom face, said pasty product being spread on the support by passing through the first opening (s) and then scraped off using a scraper. The invention also relates to a device comprising a container and a scraper, which container comprises an open face and a bottom face, the open face being opposite to the bottom face, said bottom face being provided with at least a first opening. which extends over at least a first portion of the length of this bottom face. The invention allows to deposit on the support, for example the top of a wall in construction, at least one strip of pasty product, for example binder such as for example mortar or glue. Said at least one strip will thus be of predetermined shape and size and positioned at a predetermined distance from at least one edge of the support. Such a method and such a device are known from US Pat. No. 5,035,352. According to the method known from this US patent, the pasty product is introduced into the container by its open face. The container is then rolled on the support and the pasty product is brought by means of a worm screw towards the first openings to spread it on the support. The device according to the prior art therefore functions as an extruder. The presence of a scraper on the outer face of the transverse face of the container makes it possible to scrape the spread product to thus size the strips which are applied on the support.

A disadvantage of the known method and device is that it requires the displacement of the twisted container of the application by extrusion of the strip on the support. Not only the container with the pasty product is heavy and therefore requires effort to move it, but the inequalities that are present on the support, especially when it is a wall of concrete blocks or bricks, make that the displacement is not without imposing vibrations on the container which will negatively affect the precision with which the band will be applied. In particular for masonry bricks with thin horizontal glue joints 3 to 4 mm thick, this is a real problem for the masons and does not allow them a speed of construction. Finally the fact of using a worm to bring the product to the openings requires maintenance of the device because it is necessary after each use to clean the endless screw to prevent it from being obstructed by the product having hardened on the surface of the worm. The object of the invention is to provide a method and a device for applying at least one strip of a pasty product which makes it possible to obtain a high degree of precision during the application of the strip while having a rapid application of the strip. application and low maintenance of the device. For this purpose a process according to the invention is characterized in that for spreading and then scraping the pasty product, the scraper is introduced through the open side into the container, which scraper comprises a profiled side so as to be provided with at least a second opening, the second opening (s) extends (ent) each time on a fraction of said profiled side and is or are arranged (s) so as each time correspond with one of the first openings when the profiled side of the scraper is facing the bottom face in a position ready to apply the pasty product, and in that the scraper is positioned on the bottom face inside the container so that for the strip or bands to apply one or the second openings correspond to one or the first openings, and then the scraper is required to be translated along at least the said first part while keeping the container in place on the support, which translational movement comprises the spreading of the pasty product followed by scraping of the spread product to form the at least one band and to evacuate a surplus of applied product.

The device according to the invention is characterized in that the scraper comprises a side having a width dimensioned to be able to allow the inside of the container a translation movement of the scraper at least along said first part of the length, which side of the scraper is profiled so as to be provided with at least a second opening, the second opening (s) extends (ent) each time over a fraction of said profiled side and is or are arranged ( s) so as to correspond with one of the first openings when the profiled side of the scraper is placed on the bottom face in a position ready to perform the translational movement to spread and scrape the pasty product.

The fact of imposing a translation movement on the scraper which is placed inside the container, which itself remains in place when the scraper undergoes the translation movement, has the consequence that the application of the pasty product on the support is not done by extrusion of the pasty product from the container. The container thus does not undergo vibrations which affect the accuracy of the application of the strips. It is sufficient for the mason to impose on the scraper the translational movement to spread the pasty product, which is an easy operation to perform and even with great precision. The fact of first spreading the product and then scraping it with the scraper, allows a precision during the application, because by scraping the spread product scraping will allow, thanks to the second or second openings, great precision in the application of the band. When the work is finished it will suffice to clean the scraper and the container, which can be done quickly and without having to disassemble. Moreover having one or more opening (s) in the bottom face and one or second opening (s) in the scraper will allow to apply one or more strip (s) of different dimensions using a set of scrapers having one or more second aperture (s) of different dimensions.

A first preferred embodiment of the process according to the invention is characterized in that to supply the pasty product it is deposited on a second part of the bottom face, which second part is offset in the direction of the length relative to the first part, and in that the pasty product is spread from this second part. The second part thus serves as a reservoir for the pasty product. The application of the product will then be made from this second part.

A second preferred embodiment of the method according to the invention is characterized in that after having spread and scraped the strip, the container is moved by lifting it relative to the support and then redeposit it on the support so as to continue the process. spreading of the band. It is sufficient to lift the container and move it to continue the application of the tape.

A third preferred embodiment of the method according to the invention is characterized in that the container has a transverse face provided with at least a third opening (S6) which extends over a portion of this transverse face, each of the first and third openings being arranged such that each of the third openings are aligned with at least one of the first openings, and that after having spread and scraped the strip, the container is moved by sliding on the support for then continue spreading the band. It is thus sufficient to slide the container on the support to continue the application of the band. Since during this movement there is no application of the product, the band already applied will not be affected by this displacement.

A first preferred form of a device according to the invention is characterized in that each third opening has a width greater than that of the first opening with which it is aligned. This helps not to damage the band (s) already applied (s) when sliding the container on the support.

A second preferred form of a device according to the invention is characterized in that the container is equipped with an abutment applied on an external lateral flank of the container. The stop allows positioning the container relative to the support to ensure that the strips are applied to the correct location on the support.

In the drawings the same reference has been assigned to the same element or a similar element. The invention makes it possible to deposit on a support, for example a wall, one or more strips of mortar or glue through the partially open bottom face of the container and this preferably recessed with respect to the edge of the wall in order to avoid any overflow and waste of binder during the placement of bricks or blocks. To vary the amount of binder to be deposited, simply change the height of the recessed portion of the scraper. The higher it will be, the greater the amount of binder deposited on the support, and so the height of the horizontal mortar joints can be easily adapted. One can work with the same thin-jointed container with glue or at larger joints if mortar is used. Only the scraper is to change. It will thus be possible by modulating the height of the joint to fall to the right height with the masonry lines compared for example below and above the bays and using scrapers whose recessed portion would be adapted to increase or decrease the height of the at least one strip of mortar.

The container and scraper, which make up the invention are indissociable and together achieve the goal. This includes the economy of pasty product, speed of execution, cleanliness, ease of use, adaptation, manufacture and cleaning after use. The invention relates to a first and a second part adapted to each other and complementary. Said first part is a container which makes it possible: to contain a reserve of pasty product sufficient to deposit up to several meters of band of pasty product without having to refill the container with pasty product. to confine the pasty product inside this same container while it is spread on the bottom of the container or that the at least one band of pasty product is formed, avoiding any loss of product as well as dirtying the support and the ground. Containment is performed on all four sides of the container. positioning the at least one strip of pasty product on the support with respect to at least one edge of this same support. depositing on a support at least one strip of pasty product with a thickness that can range from 2 to 30 mm, without having to modify the container. to guide the scraper laterally and vertically as it moves into the same container. to be moved by sliding it on the support after having begun to deposit the at least one strip of pasty product and before continuing to deposit it. to present only a very small surface in contact with the at least one strip of pasty product, thus making it possible to avoid any problem of adhesion of pasty product on the container during demoulding. -to be made cheaply from common materials and equipment.

Said second part is a scraper intended to spread the pasty product on the underside of the container and then by bearing on it and by leveling the same face, to form the at least one strip of pasty product to be deposited on the support. The underside of the container and the scraper are of small thickness which limits the contact surface of the device with the pasty product and which prevents the device from getting dirty quickly and facilitates the demolding of the at least one strip of pasty product formed and deposited on the support using the device.

In a first phase, the container is supplied with pasty product. In a second phase, the container is positioned on the support. In a third phase is spread on the underside of the container pasty product with the scraper and then scraped the underside of the same container with the same scraper by positioning it perpendicularly to the side walls and the bottom of the container . In a fourth phase, the container is preferably slid on the support but it can also be lifted and thus completely free of the support before depositing it again on the same support. All these operations are then repeated in order to obtain the at least one continuous and dosed strip of pasty product deposited on the support.

To supply pasty product the container is deposited pasty product inside this container on its bottom, ie on its underside and the side where it is not openwork. The amount of pasty product that can contain the container is sufficient to deposit on a support the at least one strip of pasty product of length greater than at least the length of the container but preferably at least one band several meters long.

The side walls and the bottom of the container are used to guide and position the scraper while it spreads the pasty product and forms the band of pasty product. During this operation the container previously placed and positioned abuts on the support does not move. Only the scraper should be operated.

The container is provided with at least one stop which when it is brought against the support, will deposit on the same support the at least one strip of pasty product at a predetermined distance from at least one edge of the support.

Preferably the height of the container and therefore that of its lateral faces will be sufficient, ideally between 2 and 10 cm, to prevent the pasty product from coming out of this same container by passing over these same side faces when one goes move this same pasty product with the scraper into the container.

The pasty product intended to fill the vertical joints of the masonry may be applied to the vertical wall of the blocks by means of a container specially arranged to deposit the at least one mortar strip in a vertical position.

For bricks a container adapted to the type of brick allows to position, align and maintain them while with the container and the scraper is deposited the at least one strip of pasty product on their endisse. At this time the container will be positioned horizontally and will in one go to deposit the pasty product on several bricks at a time. The container can also bring all these bricks at once near the wall under construction. The use of a brick container and the possibility of storing a large quantity of pasty product in the container will greatly limit the number of movements and movements of the masons during the construction of a wall. They will be less physically challenged although their pace of work is faster.

A preferred embodiment of the device according to the invention is characterized in that the container is of parallelepipedal shape, that its upper face is open, that its lower face is partially open and that at least one of its four lateral faces is partly open and equipped with a stop and the scraper is of a smaller width than the inside of the container and is provided with a handle and that the edge opposite the handle is partly set back from this same edge.

Preferably the invention will be constructed of sheet metal but it could be made of plastic or any other material for its manufacture and use.

Figs. 1 and 2 illustrate an example of a container (20) and a scraper (9) forming part of a device according to the invention.

The face (3) of the container (20) has an opening (S6) of width (I3) greater than at least 2 mm, the width (11) of the opening (S1) and a height (H1) smaller that the height (H) of the container (20) but preferably higher than the height (H2) of at least 3 mm from the recessed portion of the side (10) of the scraper (9). The opening (S6) of the side face (3) extends the opening (S1) of the lower face (6) of the container (20) on the same side face (3).

The at least one opening (S1) preferably extends between the lateral face (3) and the surface (S4) of the lower face (6) of the container (20). The openings (S1) and (S6) although of different widths, are centered relative to each other. The widths (I2) and (I8) respectively of (S2) and (S3) may be the same or different.

The surface (S4) is = or> one quarter of the total surface of the lower face (6) of the container (20). (S1), (S2) and (S3) are respectively of width (11), (I2) and (I8) constant over their entire common length (LI).

The container (20) is provided with a stop made preferably in two separate parts (7) and (8) spaced from each other by a length (L4) greater than the width of the container from minus 1 cm in order to ensure the continuity of the at least one band of pasty product (14) deposited on the support (13) when there are two supports (13), (15) which intersect (Fig-12). The abutment portion (7) is of length (L3) at most equal to the length (L2) of (S4) and the abutment portion (8) will be of maximum length (L5) = (L1) - (L4) - 1cm.

In addition, the container (20) illustrated in FIG. 5 is characterized in that it is compartmentalized. This version of the invention is intended to limit the effort to be applied to the scraper (9) to form the pasty product strips. Indeed in some cases it is possible if we have 3,4,5,6 and even more bands of pasty product to be deposited on the support that is limited to deposit for example only 1 or 2 strips of pasty product at a time.

FIGS. 7,8,9,10,11 illustrate some possible models of scrapers (9) according to the invention. Still other models can be used of course.

FIGS. 15 and 16 illustrate, according to the invention, an example of a device characterized in that the opening (S1) on the underside (6) of the container (20) runs along and is in direct contact with a lateral face (4). ) of this same container (20).

FIGS. 17 and 18 illustrate, according to the invention, an example of a device characterized in that the openings (S1) and (S7) present on the lower face (6) of the container (20) run along and are in direct contact with the respective side faces (2) and (4) of the same container (20). FIGS. 19 and 20 illustrate, according to the invention, an example of a device characterized in that the abutment (7), (8) of the container (20) is positioned in line with its lateral faces (2) and (3) and the surface (S4) is perpendicular to the surfaces (S2), (S3) and (S8) and to the openings (S1) and (S7). This embodiment allows according to the invention to deposit two strips of pasty product on a vertical support.

The container is positioned on the support after having supplied pasty product deposited on its surface (S4). Then, using the scraper (9) of FIG. 20, the pasty product is spread on its surfaces (S2), (S3) and (S8) and on the openings (S1) and (S7). using the same scraper (9).

Fig.21, 22 and 23 illustrate three steps of depositing two strips of pasty product (16) on a vertical support with the specially arranged container (20) of Fig.19. and its scraper fig.20.

FIGS. 24, 25, 26, 27 and 28 illustrate the chronology of the steps for depositing one or more strips of pasty product on the end of a series of bricks in one go. The container (22) empty of Fig.24 is then filled with bricks (23) and shown full by Fig.25. At this moment the bricks are positioned and kept aligned by the container. After having placed a container (20) according to the invention on the series of bricks as shown in FIG. 26, the squeegee (9) of the invention is used to form and deposit two strips of pasty product shown by FIG. fig.27on the butt of the bricks (23). These two strips of pasty product will thus form the vertical joint between the bricks when they are masonry.

In a preferred embodiment the flanks (21) of the container (22) will be of height (H4) greater than the length (H5) of the bricks of fig.28. The bottom of the container (20) is then placed on these flanks (21) and is no longer in contact with the bricks when depositing on the butt of bricks the at least one strip of pasty product.

This will result in a brick length + pasty product strip height which will be constant and which will thus make it possible to compensate for the variations in length of the bricks related to manufacturing dimensional tolerances which will facilitate the vertical alignment of the vertical joints during the construction of the wall. .

The bricks with strips (16) pasty product on their endisse will be carried to the wall under construction in one go with the container.

Although the present invention has been described with reference to specific exemplary embodiments, it is obvious that various modifications and changes can be made to these examples without departing from the general scope of the invention as defined by the claims. Therefore, the description and drawings should be considered in an illustrative rather than descriptive sense.
