DESCRIPTION
This invention concerns a storage structure for filing documents equipped with transponders, suitable to allow rapid location and identification of the documents it contains.
Public organisations, offices and libraries are known to have the need to file and store a considerable quantity of documents that must be inventoried and easily made available to the user. The filed documents can be books, folders, files or individual elements. One of the known techniques for the semiautomatic filing and inventorying of documents foresees that each document inserted in the filing system is fitted with an electronic tag commonly called a transponder. The transponder contains one or more identification parameters of the document to which it is applied and can transmit them, by means of a radiofrequency signal, to appropriate monitoring means.
In particular, the transponders monitoring means can be equipped with a mobile antenna which is moved towards each document contained in the storage structure in order to identify it, or in other cases it is the storage structure itself which is internally equipped with a plurality of antennas for the identification of the transponders.
Storage structures equipped with built-in antennas belonging to the background art essentially comprise a plurality of structures for storing items provided with transponders and means for monitoring the items consisting of a receiver-transmitter unit fitted to each of the storing structures. Each storing structure is equipped with a pair of antennas, each substantially consisting of an insulating film coated with a layer of conductive material, which are fitted on the inner surface of the structure as shown in fig.1. The antennas are connected to the receiver-transmitter unit to generate an electromagnetic field which is picked up by the transponder and provides it the necessary energy to transmit the data it contains to the receiver part of the
receiver-transmitter unit itself.
The data are then sent to a processor, operatively connected to each individual receiver-transmitter unit, where they are processed and stored. Every single item contained in the storage structure can thus be identified and easily made available to the user.
A storage structure corresponding to the features mentioned above is described in the Italian Patent application no. VI00A000168, filed by the same applicants as for this patent. All the known semi-automatic storage structures of the type described above, however, present a series of recognised drawbacks.
One recognised drawback of the semi-automatic storage systems, equipped with antennas associated with each storing structure, consists of the fact that the number of transponders that can be identified by each pair of antennas associated with the individual storing structure cannot be too high, due to the reciprocal interference that the transponders have on each other when their density is excessive.
It is therefore evident that document filing, which necessarily involves a high density of items inside each storage structure, makes the use of such systems not very suitable for filing small-size documents and/or objects fitted with transponders.
A recognised drawback, on the other hand, of structures equipped with mobile antennas for the identification of documents is the difficulty of finding each individual document quickly. In this case, indeed, it is necessary to move the antenna close to the documents stored on the shelves of the storage structures in order to identify the document being searched for.
This invention intends to eliminate the drawbacks described above. The first aim of the invention is to provide a storage structure suitable to contain a high density of documents fitted with transponders in which each individual document can be located and identified quickly and precisely.
Another aim is to provide a storage structure in which the effect of the interference between the transponders fitted to the documents stored in the structure is less than occurs in the known structures described above. A further aim is to provide a storage structure which reduces the need for the presence of an operator.
Yet another aim is that the structure according to the invention does not require mobile systems for interrogation of the transponders. These aims are achieved by means of a storage structure which, according to the main claim, comprises: - one or more shelves for filing a plurality of documents;
- at least one transponder fitted to each of said documents;
- monitoring means comprising at least one unit for receiving/transmitting radiofrequency signals to said transponders, connected to a plurality of antennas internally mounted on each shelf, and which is characterised in that said antennas consist of substantially flat laminar bodies arranged vertically and spaced at a distance from each other, these laminar bodies being aligned according to the horizontal direction defined by each of said shelves to be inserted between said documents. Advantageously, the presence of a plurality of laminar antennas positioned between the documents makes it possible to dimension the structure according to the density of documents to be stored so as to limit the number of transponders located between two adjacent antennas and to avoid the interference that occurs in the known structures described above. These aims and advantages will be clearer on reading the description of preferred embodiments of the invention, provided as non-binding examples with reference to the accompanying drawings in which:
- fig. 1 shows a semi-automatic structure belonging to the background art;
- fig. 2 shows an axonometric view of the structure according to the invention; - fig. 3 shows a detail of the structure of fig. 2;
- fig. 4 shows an enlarged detail of the structure of fig. 2;
- fig. 5 shows a transponder fitted to a document contained in the structure of fig. 2;
- figures 6, 7 and 8 show further embodiments of the structure of fig. 2. As can be seen in fig. 2, the structure according to the invention, indicated overall with 1, comprises:
- one or more shelves 2 for filing a plurality of documents D;
- at least one transponder 3 fitted to each of said documents D;
- monitoring means 4 comprising at least one unit 5 for receiving/transmitting radiofrequency signals to said transponders 3, connected to a plurality of
antennas 6 fitted inside each shelf 2. According to the invention, the antennas 6 consist of substantially flat laminar bodies 7 arranged vertically and spaced at a distance from each other, said laminar bodies 7 being aligned according to the horizontal direction defined by each of the shelves 2 to be inserted between said documents D.
In the embodiment shown in the figure, the storage structure consists of a shelving, indicated overall with 8, which comprises a support structure 9 fitted with a plurality of horizontal shelves 2. The back panel 10 of each shelf 2 is equipped with the antennas 6 positioned orthogonally to it, as can be seen in fig. 2, and connected, by means of electric cables 11, to the receiver-transmitter unit 5, which represents the unit suitable to emit and receive the signals exchanged between the antennas 6 and the transponders 3. The transponders 3, fitted to each document D, are passive transponders, of the type known per se, and are enabled to transmit the information and data they contain to the receiver-transmitter unit 5 receiving the necessary energy from the electromagnetic field generated by the antennas 6. The receiver-transmitter units 5 connected to the antennas 6 transmit the received data to a processor 12 which collects and files them, making them available to the user.
In other embodiments, the antennas can be fitted to the lower and/or upper surface of each shelf and also be placed parallel to the back panel of the storage structure. In the embodiment shown in fig. 8, indicated overall with 50, the antennas 51 are fitted to the back panel 52 of the shelving 53 and positioned horizontally to allow documents to be filed in stacks, for example inside containers and/or drawers 54 of the type shown.
In another embodiment shown in fig. 6, the antennas are fitted to mobile containers 13 of the documents D which are equipped with transponders 3 positioned on the shelves 2 and connected to one or more receiver-transmitter units 5.
As regards the antennas 6 which transmit the radiofrequency signals to the transponders 3, these are of the active type consisting substantially of a radiating element 14, a tuner circuit 15 suitable to cause each antenna 6 to resound at the working frequency of the transponder 3, and a coupler circuit 16
suitable to balance the line impedance.
The active antenna 6 is the source of emission of the electromagnetic field necessary to enable the transponders 3 and, at the same time, is the element which receives the reply signal. All the active antennas 6 belonging to one or more shelves 2 are connected to the receiver-transmitter unit 5, commonly called a transceiver, which comprises a transmitter section suitable to send the signal to the transponders 3 and a receiver section suitable to receive the signal from the transponders 3 and send it to the described data processing means 12. The storage structure 1 according to the invention can also be equipped with passive antennas, alternated with the active antennas, which are not connected to the receiver-transmitter units 5 and thus act exclusively as resounding elements for the signal emitted by the active antennas 6.
The passive antennas comprise a radiating element similar to the one previously described for the active antennas 6 and a tuner circuit suitable to make it resound at the frequency of the transponders 3.
In the described embodiment, the tuner circuit 15 is a static tuner circuit; however, in other embodiments of the invention this can also be a dynamic tuner circuit, that is to say able to vary the antenna tuning to improve the response of the various transponders.
It is obvious that the use of a certain number of passive antennas combined with active ones leads to a reduction in the cost of the structure but limits the precision of the document search.
Each radiating element 14 of the antennas 6 consists, as can be seen in fig. 4, of a laminar body 7, preferably but not necessarily made of plastic material, inside which is a conductor 17 which acts as the transmission and reception element for the signal emitted/received by the antenna 6.
Between the receiver-transmitter unit 5 and the antennas 6 are means 18 for selecting the antennas 6 which make it possible to modulate the signal transmitted by the various antennas 6.
In particular, the electromagnetic signal can be emitted simultaneously by all the antennas 6, or alternatively by each individual antenna 6 in succession, or also by predefined groups of antennas 6.
It is thus possible to modulate the electromagnetic field to detect the transponders 3 located in the most critical positions which, otherwise, would
not be reached by the signal.
Moreover, by modulating the signal to the various antennas 6 as described above, it is possible to progressively refine the search to identify each document D inside the storage structure 1. The search is made even more reliable by the presence of static or variable tuning means 19, positioned between the receiver-transmitter unit 5 and the antennas 6, which make it possible to vary the frequency of the signal emitted by the antennas 6 to allow enabling of the transponders 3 which, due to external or reciprocal interference, do not respond to their nominal frequency. If variable tuning means 19 are used, these allow one or more not enabled antennas 6, which would otherwise act as passive antennas, to be made inert by completely detuning them, reducing the precision of locating the document D being searched for. The selection means 18 and the tuning means 19 can be used as described, together or individually, to make the identification of each document D contained in the storage structure 1 easier.
Another embodiment of the storage structure according to the invention is shown in fig. 7 where it is indicated overall with 100. In this case, the storage structure 100 consists of an automatic structure, of the type known per se, equipped with a plurality of mobile shelves 20 which revolve as a closed ring on an essentially vertical plane. The antennas 21 are fixed inside the storage structure casing 22, while the transponders 3 fitted to the individual documents D are enabled and exchange signals with the antennas 21 when the revolving mobile shelf 20 passes through said antennas 21.
It is obvious that in this case the number of antennas 21 installed in the storage structure 100 for the identification of the documents D will be lower thanks to the possibility of moving the shelves 20 and consequently of using the same antennas 21 to monitor several shelves 20. Operatively, each document D is fitted with an electronic label 3 consisting of a passive transponder and the document is then inserted in one of the shelves 2 or 20 of the storage structure 1 or 100.
To find any document D present in the storage structure 1, 100 the operator enables the search procedure through the processing means 12, 23 which transmit a signal to the antennas by means of the transceiver units 5.
As described, the antennas 6, 20 can be enabled simultaneously, in succession and/or in groups to identify the required document D and to define its precise location inside the storage structure.
If the document D is not identified in this first stage, the presence of the tuning means 19 allows the antennas 6, 20 to emit a signal with a different frequency with respect to the nominal frequency, in order to identify the transponders 3 which, due for example to interference caused by other documents D, do not respond to the signal.
When the document D has been identified, the operator is informed and given the data relative to its position.
From the above description it is clear that the storage structure of the invention achieves all the preset aims.
In particular, it is achieved the aim of providing a storage structure suitable to contain a high density of documents fitted with transponders, in which it is possible to identify and locate each individual document quickly and precisely.
It is also achieved the aim of providing a storage structure in which the effect of reciprocal interference of the transponders fitted to each document is less than is found in the known storage structures.
Indeed, it is clear that the presence of a large quantify of antennas placed between filed documents makes it possible to reduce the number of transponders between two adjacent antennas and thus to avoid possible interference which prevents identification.
It is also achieved the aim of providing a storage structure that reduces the presence of an operator and does not require the use of mobile systems for transponders interrogation.
Modifications and variations not described and not shown can be made during production of the storage structure according to the invention.
Should these variations, not described and not mentioned, be within the scope of the claims that follow, they shall all be considered as protected by this patent.
