Description

Arch for loading docks.

Object of the invention

The present invention relates to an arc, of type of those destined to be implanted in the accesses to the docks of freight of goods of any warehouse, or in general of any installation where there are loading docks of commodity.

The object of the invention is to provide a arc that incorporates zenith RFID reading media, as well as a voice control system, in order to allow control automatic incoming or outgoing goods, preventing them from produce erroneous or failed readings.

Background of the invention

As is known, RFID technology, or Radio frequency identification is increasingly widespread for the detection and classification of products, so that, in The practical scope of the invention are known various equipment based on such technology, which can read labels of different sizes and prices, applied to goods, as well as other objects, in order to identify them from automatically, so that your record is stored in the corresponding computer system.

However, these types of devices have A problem that focuses on the following aspects:

?

When the labels are Applied to goods with high liquid or metal content, it is often that reading does not occur.

?

Frequently, due to the disposition of said RFID reading equipment, the reading of the desired label together with that of others nearby labels, not being able to discriminate in most cases which is the correct reading.

?

Likewise, when the merchandise to which the label is applied is stacked or compacted so irregular, the percentage of reading falls so considerable.

?

Also, in most of the cases fail or wrong readings are controlled, so that it may be the case that the labeled merchandise is loaded or process, without the management system having knowledge, and so so much the traceability of the product.

Description of the invention

The arch for loading docks of goods that the invention proposes resolves the problematic exposed above, given that, thanks to its special structuring, allows to carry out a zenith reading of the commented labels, so that reading is much more effective and accurate, by concentrating the reading area in an area concrete, that is, just low in own arc, so that, with the collaboration of a series of sensors established on the same, the readings of the products that pass under the arch, and reject labels not Wished they could be near the arch.

Thus, the arc of the invention allows carrying carry out effective control over erroneous readings or "no readings ", so that any incidence in the treatment of merchandise with RFID tags, is detected and processed ensuring its correct management.

For this, the arc of the invention is constituted from a metal structure where they go installed one or more RFID antennas in zenith position, structure to which a cabinet is associated where a RFID reader, a box of inputs and outputs and optionally, network and electronic converters for light control or mermaids

The Arc also includes, as it has been commented above, a series of sensors to capture Information about your surroundings. These sensors are configured according to the application needs, and allow to detect and discriminate the transit of people and objects and their address (if they enter or leave from the truck).

From this structuring, it is planned that the arc communicate with other computer systems through of a wired Ethernet network or WIFI.

According to another of the characteristics of the invention, the arc may include and control various lights colors, audible warning systems and Ethernet / wifi converters and Ethernet / fiber to connect to Wi-Fi networks or fiber networks. Also, optionally, said arc can operate with terminals WIFI laptops, to which you send convertible voice messages, using TTS (text to speech) techniques or with voice / ip systems. In this way, the staff that performs the task of loading the truck receives audible information through the terminal, of all the incidents that could arise. In this way, the arch allows  ensure 100% control over the loading or unloading of the truck, even in the case of a non-reading of the RFID tag, a manual process is generated, for identification of the commodity.

As for the application software, and parametrizable, associated to computer equipment through the that the device is controlled, it allows to process the readings of the labels, process signals, filter the same, obtain movement patterns of objects, fix the read and write thresholds, discriminate between these thresholds, communicate with other systems for data validation, etc. This software allows you to reject RFID tag readings, which they might be relatively close to the reading arc, but not they cross the Reading Arch, thanks to the state of the corresponding proximity sensors.

The metal structure that participates in the device will preferably have a telescopic character, in order to adapt to different sizes of springs while the support on which the antennas and sensors are placed They can be sliding, forward or backward, to adjust your position, which allows great flexibility when adapting the equipment to any installation requirement.

Finally, it should be noted that the special device structuring, mounted on walls and ceiling of the loading dock, makes the ground not present any type of element or device that prevents the free movement of machines and people, to perform the tasks of loading or unloading merchandise In the trucks.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a plan view of a bow for loading docks of goods made in accordance with the object of the present invention.

Figure 2.- Shows a block diagram, in which are represented, schematically, the different basic electronic elements involved in the arc of the previous figure.

Preferred Embodiment of the Invention

In view of the figures outlined, and in special figure 1, can be seen as the spring arch Cargo freight that is recommended is made from of a metallic structure of configuration in "U", destined to adapt to the corresponding side walls and roof loading dock, based on square section metal tubes, in which are defined as two side frames (1), preferably of inverted triangular configuration, configuration not shown in Figure 1, since said figure corresponds to a view in floor, racks between which a couple of horizontal and telescopic stringers (2), which allow the arch adapt to different widths of loading docks.

On said telescopic stringers (2), has a transverse cross member (3) longitudinally on the structure, in order to allow a large flexibility when adapting the equipment to any installation requirement, crossbar (3) in which they install, in their middle zone a double RFID antenna (4), arranged in zenith position, as well as at its ends two sensors anterior (5) and posterior (6) presence through which it is possible to detect and discriminate the traffic of people and objects as well as your transit address.

The arch is complemented by a side cabinet (7) in which an RFID reader (8) is established as well as the corresponding control electronics, cabinet associated with a box of connections, inputs and outputs (9), with the corresponding power supply (10), and being able to optionally incorporate network converters (11) as well as the electronics for controlling lights or sirens (12).

Through control electronics established in the aforementioned closet (7), and of the corresponding programming software, the arc communicates with other systems through a wired Ethernet network or WIFI, for means of said network converters (10), allowing processing label readings, process signals, perform a filtering them, get movement patterns of the objects, set reading and writing thresholds, discriminate between these thresholds, communicate with other systems for data validation, etc., and can also reject readings of RFID tags, which could be relatively close to the arc without going through it.

According to another of the characteristics of the invention, the system may include warning systems (13) hearing aids, being able to operate with portable WIFI terminals, at that sends convertible messages into voice, using TTS techniques (text to speech) or with voice / ip systems. In this way, the Personnel performing the truck loading task receives audible information through the terminal, of all incidents that could arise.
