Description

DESCRIPTION

ROBOT FOR MANEUVERING FOLDING PEDESTRIAN GATES

OBJECT OF THE INVENTION

The present invention refers to a robot for maneuvering folding pedestrian doors, usable in the technical sector of access and door automation.

BACKGROUND OF THE INVENTION

For access control in conventional pedestrian doors, which are folding with a vertical axis, the best-known implementation is that of an electric strike with a tilting sector, what is known as an “automatic intercom”, which allows said strike to be powered remotely to that the door can be opened by pushing manually

Additionally, automatic opening mechanisms can be implemented, which usually comprise oil hydraulic cylinders, actuated by a hydraulic unit whose pump is controlled by limit switches arranged in the extreme opening and closing areas, so there is no control in areas intermediate, and any access, even if it is quick and by a single person, implies a complete opening and closing cycle, with times that can lead to the door being open longer than necessary and favoring unauthorized access, and greater energy consumption. of those necessary. Furthermore, the installation of the maneuver requires multiple distributed elements (limit switches), which increases the cost of material and assembly labor, in addition to complicating it, which is solved with the use of the robot of the invention. .

DESCRIPTION OF THE INVENTION

The robot for maneuvering folding pedestrian doors (such as pedestrian doors at the entrance to buildings, in communities of owners) of the invention comprises a structure with fixing means (any type of anchoring: screws, clamps, welding, etc.) to the door. , in the vicinity of its free end, and where they are mounted:

-a drive motor, coupled to a drive wheel, to produce the opening and closing movement of the door,

-an inertial measurement unit (IMU),

-at least one operation reader (an element that receives access request readings, and when reading identifies that it is an authorized access, sending the corresponding opening or closing signal),

-a control unit, connected to the previous elements, which receives validation from the operation reader and therefore knows that it must command the opening of the door by powering the drive wheel motor, as well as command the closing once a certain period has elapsed. given time, provided with a configuration interface to very simply parameterize speeds, accelerations, end separations, thrust levels, sound, etc..., based on the IMU readings, which include accelerations, absolute positions and orientations , and

-a power supply for the robot elements.

With this configuration, at least the following advantages are obtained:

-The installation is carried out in a very simple and modular way, without practically any work, reducing costs,

-the opening angle at which the door is located is constantly monitored and interpreted by the robot through the IMU, which significantly increases operating safety,

-The IMU also allows you to dispense with limit switch type actuators or encoders that are necessary to control other types of door opening actuators, simplifying the installation,

-The IMU also detects variations in acceleration due to obstacles, causing the movement to stop,

-In the event of a total power failure, the door can be opened perfectly manually without making greater efforts, simply by pushing it, previously acting on any lock it may have.

PREFERRED EMBODIMENT OF THE INVENTION

The robot (1) for maneuvering folding pedestrian doors (2) of the invention comprises a structure (3), with means for fixing to the door (2), and where they are mounted:

-a drive motor (30), coupled to a traction wheel (4),

-an inertial measurement unit (5) (IMU) (see fig. 3),

-at least one operation reader,

-a control unit (7), with a configuration interface (70), connected to the previous elements, and

-a power supply (8) for the different elements.

The operation reader can be for example one or more of the following:

-a Pir type sensor (6),

-an Rfid type sensor (6a), which allows you to open the door by simply carrying one of these coded and authorized cards, without even having to take it out of your pocket, -a push button,

-a face-to-face radar,

etc

It is preferred that the traction wheel (4) has a rounded tread (40), which facilitates traction with a curved trajectory as the door is foldable. Furthermore, it is preferred that the wheel (4) is mounted on the structure (3) through a support (41), sliding on guides (43) with a recovery spring (44), which achieves the necessary pressure against the ground. to achieve traction and at the same time absorb irregularities.

For its part, the power supply (8) comprises mains power (80) and very preferably, in a complementary manner, it may comprise a rechargeable power battery (81), which allows a large number of openings and closings in case of absence. mains power supply. Furthermore, in this case the arrangement of battery temperature and voltage sensors (81a), and a charge control sensor (81b) is preferred, which always keeps the battery in optimal condition.

As for the interface (70) of the control unit (7), it ideally comprises a waterproof button panel (71) and a display (72), although it could be a touch screen, or similar.

Finally, indicate that, preferably, the robot (1) comprises a protective casing (9) (which can integrate the structure itself, or be mounted on the structure) and that protects all its elements, leaving only the operating logic accessible. (interface, wheel...). In addition, it also incorporates an emergency stop button (12). Likewise, the casing (9) will have an upper operable cover (90) that protects a connection terminal block (91).

Having sufficiently described the nature of the invention, it is indicated that the description of the same and its preferred embodiment must be interpreted in a non-limiting manner, and that it covers all the possible embodiment variants that can be deduced from the content of this report. and the demands.
