Description

[0028] The description is set out below with reference to the accompanying drawings which are provided solely for purposes of illustration without restricting the scope of the invention and in which:

[0029] FIG. 1 is a schematic side view of a first embodiment of a system for controlling and managing fabrics according to the invention;

[0030] FIG. 2 is a schematic top view of the first embodiment shown in FIG. 1;

[0031] FIG. 3 is a schematic side view of a second embodiment of a control and management system according to the invention.

[0032] The reference numeral 1 generically denotes a system for control and management of fabrics T according to the invention.

[0033] The system 1 for the management and control of fabrics T comprises a first station 2 designed for moving a fabric T, a second station 3 also for moving the fabric T operatively connected to the first station 1.

[0034] FIGS. 1 and 2 show a first embodiment in which the first 2 and the second 3 comprise respective cylinders 4, 6 for supporting and moving the fabric T which in this solution is wound in respective rolls 15, 16.

[0035] The first station 2, and also, vice versa, the second station 3, may unwind or wind the roll 15 and 16 as a function of the feed direction requested by the user of the system 1.

[0036] FIG. 3 shows, on the other hand, a second embodiment of a system 1 according to the invention wherein the roll 15 of fabric T is replaced with a zone 17 for rolling the fabric T.

[0037] In this second solution the second station 3 can wind the fabric T in the roll 16.

[0038] The system 1 also comprises a light source 7 positioned in an intermediate position between the first station 2 and the second station 3 configured to illuminate from the bottom upwards a predetermined portion TX of the fabric T.

[0039] The predetermined portion TX of the fabric T is the portion between the outfeed of the first station 2 and the infeed of the second station 3.

[0040] The light source 7 may be any light source, generally halogen, neon or LED.

[0041] The light source 7 may be positioned below a transparent or translucent panel which serves as a support surface for the portion TX of the fabric T passing.

[0042] The system 1 also comprises an optical device 10 for acquiring an image or a video of the predetermined portion TX of the fabric T.

[0043] The optical device 10 may comprise any device for acquiring individual images (cameras) or in sequences of images (video cameras).

[0044] The optical device 10 is positioned advantageously above the first 2 and second 3 station, for example installed on a respective support, and faces towards the portion TX of fabric T in question.

[0045] The system 1 for controlling and managing fabrics T according to the invention also comprises a data processing and storage unit 8 connected to the optical device 10 and configured for associating identification information of the fabric T with the image and/or video of the predetermined portion TX of the fabric T.

[0046] Merely by way of an example, the data processing and storage unit 8 may associate with a photograph and/or video acquired of the portion TX of the fabric T information, as well as the commercial name and the design of the fabric, relating to any chromatic or structural defects present, predominant colours present in TX in such a way as to catalogue the fabric T into specific colour categories (red, yellow, green . . . ), repeated geometrical patterns so as to catalogue the fabric T in specific categories (squares, rows, circles etc.).

[0047] These catalogues of the fabric T detected automatically through the system 1 according to the invention allow a subsequent search in the database which is easier and optimised by the users who can make selections not only by searching for the name of the fabrics, as currently known, but also by searching for chromatic and/or geometrical characteristics of the fabrics.

[0048] Therefore, merely by way of example, a system 1 according to the invention allows a user to search in a database for all the fabrics T with predominance of red and hatched pattern or other types of selection which are advantageous for the purposes of managing the store and the sales orders.

[0049] Advantageously, the control and management system 1 according to this invention also comprises a second light source 14 also positioned in an intermediate position between the first station 2 and the second station 3 and configured to illuminate the predetermined portion TX of the fabric T from the top downwards.

[0050] Depending on the type of control or operation of the system 1 according to the invention it may be advantageous to switch on only the first light source 7, only the second 14 or both.

[0051] Preferably, the system 1 also comprises a metric feedback device 12 positioned below the predetermined portion TX, for example on the supporting surface, and facing towards the optical device 10.

[0052] The metric feedback device 12 is used for storing a further parameter of the fabric T in the storage unit 8, that is, the actual height of the fabric T.

[0053] To obtain this, it is sufficient for the optical device 10 to acquire the image and/or the video of the fabric T positioned above the metric feedback device 12 which will protrude laterally from it and reveal the overall dimension of the height of the fabric T.

[0054] An alternative embodiment of the metric feedback device 12 may comprise a bar with a plurality of photocells positioned facing the lower surface of the fabric in such a way as to detect the presence or absence of the fabric at a predetermined single photocell, that is to say, its overall height.

[0055] The system 1 also advantageously comprises at least a first transversal cutting device 11 positioned between the first station 2 and the second station 3 for cutting the fabric T along a transversal direction Y.

[0056] This operation can be used when it is necessary to obtain different rolls of fabric T having the same height but different thicknesses from a roll of fabric T.

[0057] Advantageously, moreover, the system 1 may comprise a second longitudinal cutting device 18 positioned between the first station 2 and the second station 3 for cutting the fabric T along a longitudinal direction X.

[0058] The cutting device 18 is advantageously mounted on a respective linear guide 9 in such a way as to be easily positioned by the user.

[0059] This operation can be used when it is necessary to obtain different rolls of fabric from a roll of fabric T having different heights and equal thicknesses, for example during sampling operations.

[0060] Moreover, advantageously, the control and management system 1 according to the invention and in particular the first 2 or the second 3 station comprise means 5 for measuring the weight of the fabric T.

[0061] The weight measuring means 5 may, for example, comprise load cells or devices which are similar and suitable for the purpose.

[0062] In order to allow the winding and unwinding of the rolls of fabric T in the first 2 and/or in the second 3 movement station, these comprise at least one motorised cylinder 4, 6 which in direct contact with the roll of fabric T allows the rotational movement of the fabric.

[0063] The motorised cylinder 4, 6 preferably also comprises an integrated metre counter device configured to measure the length of the fabric T.

[0064] In this way it is possible to also make the unit 8 store the total length of the roll of fabric T.

[0065] This function is very advantageous both in the step of first passage of the fabric T on the system 1 (that is, after the production) and for any subsequent steps following partial orders relative to the total length of the roll of fabric T.

[0066] In effect, it will be possible to keep the company's database always up to date with the available lengths of the various fabrics T instant by instant, optimising both the management of the warehouse and the sale.
