Description:
Motorized Reducer with Electromechanical Limit Adjustment TECHNICAL FIELD

The invention is related to a motorized reducer with electro-mechanical open/close system which is driven by AC or DC motor, gear ratio is provided by means of the reducer; it can be used in many areas with its compact structure, consists of electromechanical limit adjusting system with motorized reducer, provides required low speeds of the high motor speed by means of the reducer gear system, allows the open/close system for giving permission to open and close at required measures, takes the system under electronic protection, enables opening and closing of the greenhouse windows at desired condition, optionally stops the system during problems to be encountered in opening and closing process of greenhouse windows, it can be adjustable by means of the electro-mechanical structure with high precision and easy status adjustment by the electronic sensors within the mechanical structure rather than the manual adjustable system and automatic adjustable system used in the opening-closing systems of the greenhouse windows or can adjust the motion of the mechanical structure with the step motor or the selected structure in an automatic manner, it can use full automatic options, can enable opening-closing by means of compact precise ways on the electronic card rather than the electronic cable.

STATE OF THE ART

In the greenhouses, the internal section of the greenhouse is required to be kept within a determined temperature and humidity range according to the weather conditions. To this end, the greenhouses are ventilated at determined times by means of opening/gathering the covers from their side or top portions. The motorized gear boxes/reducers are used for gathering the cover of the greenhouse in the ventilation of the greenhouse. Meanwhile, reducers which require torque, low speed or only mechanical limit adjustment can be used as an open/close system in many fields.

It is understood that when the utility model registration No 2013/00031 titled as “a switch-controlled electromechanical-system assembly determining the stop points in the geared motors” detected in the research made in the present state of the art is analyzed, some disadvantages are seen. These disadvantages will be explained herein below. Also in the system disclosed in the patent application No 2018/06877 titled as “Motorized Reducer with Smart, Mono-block and Compact Open/Close System” whose application is made by us, there is no structure which enables any limit adjustment.

Some of the determined disadvantages of the systems used in the present state of the art are as follows:

• When the material quality of the springs included in the micro switch structure used in the mechanic limit adjustments and their function losses based on fatigue happens, it leads to failure, collapse etc. damages in the systems used in opening and closing processes by means of exceeding the limit and in case the contact ends included in the micro switch structure used in mechanic limit adjustments are subjected to high currents, it leads to adhesion problems and the spring within the micro switch fails to fulfill its function, thus the system receives continuous signal and cannot be able to move.

• Only mechanical adjustment is made in a difficult manner in the systems with mechanical limit adjustment, in addition to this micro switch is used in all mechanical systems and it is made only by electronic adjustment in the systems with electronic limit adjustment, in addition to this sensors count the pulses and cannot catch the limit value directly.

• Limit adjustment control cannot be made by the structure with mechanical limit adjustment; the millimetric value of the adjusted limit in manual adjustment is determined by trial and error method. The limit adjustment of the electronic limit adjustment system is made by holding the limits pressed on electronic card or panel and defining the location, additional processes are performed by means of the read pulse on the ramps in accordance with the structure of AC motor.

• The distance covered by the limit in the mechanical limit adjustment systems cannot be estimated in millimeters and in electronic limit adjustment systems it can be seem in millimeters by means of additional card, display and calculations.

• Negative conditions such as electronic cable confusion of the mechanical system and movement of some cables etc. are experienced and electronic card comprises more complex elements although there is no such confusion in the electronic system.

• Serious problems are experienced based on the delayed activation of the motor protection switches used in the motor panel systems with reducer which are subjected to high currents and economical cost is increased although extra protection is provided by means of the current sensor in the electronic systems. * The limit adjustment is not appropriate for the remote control in mechanical limit adjustment systems and the limit adjustment in electronic limit adjustment systems is possible when it becomes permissible by means of software changes with additional card and calculations.

• It requires additional systems for remote control by making changes directly on both systems as the mechanical systems and electronic systems and by making changes directly on the panel.

Consequently, a development is required in the relevant technical field of the motorized reducer with electromechanical limit adjustment due to the presence of the abovementioned problems and insufficiency of the current solutions.

AIM OF THE INVENTION

The present invention is related to a motorized reducer with electromechanical limit adjusting which fulfills the abovementioned requirements, eliminates all disadvantages and brings some additional advantages.

The problems solved by the invention and the aims required to be achieved are as follows:

• In the mechanical limit adjustment system, instead of mechanical switching element micro switch, with methods as sensors (radiation, magnetic, electrical) which will provide high precision, low voltage and high economic life, in the electronic limit adjustment system process is performed by receiving single pulse value by means of providing the movement of the sensor and the detector within limit value without pulse counting. In sensor system, negative conditions will be eliminated by means of eliminating the disadvantages of both systems and providing high precision and accuracy. If necessary, the system confirmation degree can be increased more by performing pulse counting and pulse viewing.

• The electromechanical limit adjustments can be made in a manual-electronic manner, the mechanical limit adjustment and limit delimiter can be made in the first manual adjustment, both sensor threaded rod and mechanic threaded rod adjustment can be made, the system is operated when the limit range sees the sensor without pulse counting with the help of the sensor, an additional second sensor enables safety. Together with the microprocessor which can be used optionally, millimetric progress is calculated and the sensor permits controlling the accuracy of the required conditions Sensor adjustment can be made with optional alignment motor (step motor).

• Instead of mechanical based micro switches used in the electromechanical limit adjustments, using optical, magnetic etc. systems, extended economic life and zero error operation can be provided, in electronic-card systems it is taken under control with the mechanical structure which eliminates pulse counting condition.

• The system is allowed for resetting between the limits by means of providing the control and confirmation of the mechanic system by the electronic system in a millimetric manner.

• The limit can be reset by the sensors located at the beginning and end of the limit on electromechanical system and the distance covered can be viewed directly from the control panels as a millimetric progress if it is required in millimeters.

• It eliminates disadvantages by means of its long lasing structure with more simple-stable mechanic and precise electronic system via the paths on the card of the electromechanical system.

• The damages which will occur as a result of reducing the high voltage to low voltage by the electronic components used on the electromechanical card can be minimized and the problems to be experienced are eliminated by the high safety based on the current protection by the current sensor or circuit to be used on the card optionally

• Our most important optional novelty is the precise remote limit adjustment over the system as a result of the fact that the sensor from limit adjustments allows for remote adjustment by the motion of the step motor which moves the screw shaft. It allows unidirectional adjustment or bidirectional adjustment; however unidirectional adjustment is preferred more since it is more effective.

• By means of entering the step motor limit status on the system in a manner such that it can be performed only upon user requests, entering the limit value on the electromechanical limit adjustment mechanism or on the panel is performed.

The structural and characteristic features of the present invention will be understood clearly by the following drawings and the detailed description made with reference to these drawings and therefore the evaluation shall be made by taking these figures and the detailed description into consideration.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, preferred embodiments of the inventive motorized reducer with electromechanical limit adjustment (A) are described only for clarifying the subject matter and without creating any limiting effect.

The electrical connections and energy of the inventive Motorized Reducer System with Electromechanical Limit Adjustment (A) is provided by means of an electric panel (100), electronic remote control of the system is provided by means of the control center (101) positioned on said electric panel (100) (Figure-1 and Figure-2). Also, the system can be controlled by means of the control center-a (263) positioned on the reducer (200).

The inventive reducer (200) is driven by an AC/DC motor (201), comprises a body (202) in which all elements are located. The motion performed by means of the power transfer element (204) within said body (202) is brought to the required limits by means of the gear set (203), transferred to the threaded rod (205) where it exits the system (Figure-3). The power transfer element (204) is appropriate for operating in a manner such that it can be threaded or belted. The inventive electromechanic limit adjustment system (250) of the inventive Motorized Reducer System with Electromechanical Limit Adjustment (A), in which; open/close system is put under the electronic protection when the open/close system allows for opening and closing with desired sizes, the system is enabled to be stopped optionally during the problems experienced when the greenhouse windows are opened and closed, electronic and mechanical structure are combined by adding superior features from the manual adjustment system and automatic adjustment system used in open/close systems of the greenhouse windows, its high precise location can be adjusted by means of easily adjustable mechanical structure via electronic sensors or the motion of the mechanical structure can be entered by means of step motor or full automatic options can be used which can make automatic adjustment with the selected structure, it can be applied to the motorized reducers (200) with electromechanical open/close system with compact precise ways on the electronic card rather than the electronic cable.

Electromechanic limit adjustment system (250) is positioned within the reducer body (202). Therefore, the motor (201) starts to operate as a coupled system with the electromechanic limit adjustment system (250). Under the electromechanical system control which is adjusted with the energy coming to the system from the cable connection point (261), AC/DC motor (201) is operated. Operation within the limit adjustments is provided by means of providing the rotation of the threaded rod (205) of the electromechanic limit adjustment system (250) with the power transfer element (204) over the reducer (200). Said threaded rod (205) is suitable for operating with at last one screwed system. The system can operate similarly by means of increasing it as two and three. A mechanical stop screw (256) and a mechanical stop element (257) are situated on said threaded rod (205).

The system operates by completing the cycles by means of the switching element (260) on the card via the bobbin ends of the motor power contactors. When forward or backward limits are obtained, a signal comes to the forward or backward switching elements (260) by means of at least one sensor (252) on the electromechanical limit adjustment system (250), operation is provided within the adjusted limits. The system is operated by means of feeding thereof with the low voltage having low requirement from the system over the panel (100) on the electronic card or by means of providing low voltage with low requirement by the current voltage adjustment element (258) coming on the electronic card. The system allows for providing an extra safety with an additional current protection sensor (262) to the system. The system permits using a microprocessor (259) for learning, memorizing processes which required precision level accuracy and millimetric alignment according to the user requests and the usage field. The operation of the system can be performed by means of sensor (252) and key elements (260) without microprocessor (259) and current protection sensor (262). The limit border can be fixed by making limit stop adjustment by the screwed structure on the mechanical threaded rod (205). Said threaded rod (205) is given with maximum limit adjusted and it will be possible if the user requires changing this adjustment manually. The system is started with the start process by means of entering the limit value in millimeters from the control center (101) on the panel (101) or the control center-a (263) on the electromechanical limit with the limit alignment motor (251). The mechanical limit threaded rod (205), single or double used sensor of the limit delimiter (255) and sensor detector (253) numbers can be increased for completely providing safety. Said sensors (252) are positioned on a sensor threaded rod (254) which is driven by the limit alignment motor (251), it can be moved on the electromechanical system along the sensor detector. The user can be able to move the sensor or sensor detector upon his/her request.

It is appropriate to add measurement sensors such as temperature, humidity, noise etc. on the electronic card upon the user demands. By means of the communication through the electronic card, the remote operation of the system can be performed.
