Sorting line for ceramic products particularly tiles, with modular packaging station

Description

[0001] The present invention relates to a sorting line for ceramic products, particularly tiles, with modular packaging station.

[0002] Sorting lines are used mainly in the ceramics industry to sort the quality of the finished products, constituted by tiles in the specific case, and to then route them to packaging.

[0003] Conventional lines essentially consist of an elongated frame along which a tile conveyance line runs, specifically in the upper part; said tiles arrive from a sorting table, where one or more operators apply coded markings to the surfaces of the passing tiles with writing means whose strokes can be detected by adapted readers arranged along the conveyance line.

[0004] Proximate to the readers there are provided stations for stacking the tiles, which are separated one another according to the classification produced by the sorting performed upstream.

[0005] Each station is capable of forming a stack which, once it has been completed with a preset number of tiles, is deposited on a second conveyor arranged in the lower part of said frame and conveys said tiles to the final station for so-called wraparound packaging.

[0006] In conventional lines, the final station is an integral part of the lines and is rigidly supported by the same frame that constitutes the main framework of the line.

[0007] This means that each line can be used for packaging only one type of product, so that when it is necessary to change the packaging it is necessary to either purchase a second line built specifically for the new requirement or to provide a sort of parallel line which merges into a second twin station which has different packaging characteristics.

[0008] In the first case, the costs to be sustained double, while in the second case they increase significantly, besides requiring a considerable availability of space at the site where the line is used.

[0009] Another problem of conventional lines is the fact that maintenance on the packaging machine is highly troublesome, owing to difficulty in accessing the elements that compose it, and that it is necessary to stop the entire line during the maintenance. Since one of the lines is capable of producing a turnover equal to a few million lire/hour, it is necessary to minimize any stoppage.

[0010] The aim of the present invention is to solve the above mentioned problems of the conventional art, providing a sorting line for ceramic products, particularly tiles, with modular packaging station which allows to have multiple types of packaging available for a single line.

[0011] Within this aim, an object of the present invention is to provide a sorting line for ceramic products, particularly tiles, with modular packaging station which allows to avoid interrupting the operation of said line for maintenance, facilitates the maintenance and furthermore does not require more space than required for simple conventional lines.

[0012] This aim and object and others which will become apparent hereinafter are achieved by a sorting line for ceramic products, particularly tiles, with modular packaging station, composed of a main frame which supports a plurality of stacking stations served by a tile feeder line which cooperates with a plurality of means for extracting said tiles from said conveyance line, and for depositing the formed stacks on a second lower conveyor to send them to a final packaging station, characterized in that said final packaging station is mounted on an independent modular frame which is rotatably/detachably articulated, by articulation means, to the end of said main frame, to which it is connected without discontinuities by means of adapted elements.

[0013] Further characteristics and advantages of the present invention will become apparent from the description of a preferred embodiment of a sorting line for ceramic products, particularly tiles, with modular packaging station, illustrated only by way of non-limitative example in the accompanying drawings, wherein:

Figure 1 is a reduced-scale side view of a sorting line for ceramic products, particularly tiles, with modular packaging station, according to the present invention;

Figure 2 is a schematic top view of the region for the connection between the modular packaging station and the end portion of the sorting line;

Figure 3 is another enlarged-scale top view of the elements for mutually coupling the modular packaging station and the end portion of the sorting line in a possible embodiment of the invention;

Figure 4 is an enlarged-scale side view of the region for joining said end portion of the sorting line and the modular packaging station.

[0014] With particular reference to the above figures, the reference numeral 1 generally designates a sorting line for ceramic products, particularly tiles.

[0015] The line 1 is composed of a main frame 2 which supports a plurality of stacking stations, designated by the reference numerals 3, 4, 5, and 6 in the drawings, which are served by a tile feeder line 7. The line 7 cooperates with a plurality of means 8 for extracting the tiles from the line 7 for conveying and depositing the formed stacks onto a second conveyor 9 which is lower than, and parallel to, the conveyor 7 and is provided in order to send the formed stacks to a final packaging station 10.

[0016] The packaging station is mounted on an independent modular frame 11 which is rotatably and, if necessary, detachably articulated, by articulation means 12, to the end of the main frame 2, to which it can be locked without discontinuities by means of corresponding elements 13.

[0017] In the preferred embodiment, the independent frame 11 is articulated to the main frame 2 so as to rotate on a horizontal plane about a vertical axis designated by A; however, as an alternative, it may also be articulated so as to swing with respect to the main frame 2, i.e., rotate about a horizontal axis which lies transversely to the advancement direction of the stacks of tiles.

[0018] The articulation means 12 are composed of at least one vertical pivot 14 which coincides with the axis A and is mounted on a vertical side 2a of the main frame 2.

[0019] The elements 13 for coupling the independent frame 11 to the main frame 2 are constituted by a hook 15 for latch coupling which can be set manually or automatically and is arranged on the side 2b of the frame 2 which lies opposite to the vertical pivot 14 with respect to the longitudinal axis B.

[0020] The hook 15 is articulated, so that it can rotate, to the main frame 2 in contrast with elastic return means 16 and engages a corresponding tooth 17 correspondingly associated with the independent frame 11, which is also provided with a set of flanges 18 for the universal coupling of packaging machines of different kinds and, if necessary, of wheels to allow its movement on the supporting surface.

[0021] The operation of the invention is immediately apparent from the above description. The independent frame 11 is normally coupled to the end of the main frame 2, is essentially monolithic therewith and is retained axially by means of the pivot 14 on one side and by means of the hook 15, which engages the tooth 17, on the other side.

[0022] In this configuration, there is no discontinuity between the modular station 11 and the main frame 2, and the stacks of tiles formed in the stations 3, 4, 5 and 6 arrive, by means of the lower conveyor 9, at the packaging station 10, where they are packaged, already divided by grade.

[0023] The station 10 is provided with flanges 18 for the universal coupling of different kinds of packaging machine: this allows in practice to replace said packaging machines with others which have different characteristics. Such replacement is performed by releasing the hook 15 from the tooth 17 and by rotating the independent frame 11 about one edge, as shown in thin lines in figure 2, easily accessing the inside of the station 10.

[0024] In order to work even better, it is also possible to fully separate the independent frame 11 from the main frame 2, disengaging the pivot 14 from the corresponding rotation seat. This further allows to optionally provide both a plurality of independent frames 11, each of which is already provided with a different packaging machine, in order to have available a range which is ready for use according to the product to be packaged, and, more simply, one or more reserve packaging machines in case of maintenance, in any case reducing, in both cases, the expensive downtimes of the sorting line strictly to the minimum required for the replacements.

[0025] It has thus been found that the described invention achieves the intended aim and objects.

[0026] The invention thus conceived is susceptible of modifications and variations, all of which are within the scope of the inventive concept.

[0027] Moreover, all the details may be replaced with other technically equivalent elements.

[0028] In the practical execution of the invention, the materials used, as well as the shapes and the dimensions, may be any according to the requirements without thereby abandoning the protective scope of the claims that follow.

[0029] Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
