Definitions

  • the present invention relates to a control system for a two or more speed motorised winch.
  • the invention also relates to a method for controlling a winch of the type described above.
  • the invention has a preferred, although not exclusive, application on nautical winches in sailing boats for cruising and/or competition, or in any case in medium-large sized boats, where motorised winches with many speeds are used to manoeuvre the sails of the boat.
  • such winches are used in sailing boats to facilitate the operations under tension for manoeuvring and adjusting the sails, like for example the positioning and hoisting thereof.
  • Such operations are carried out by manoeuvring suitable lines or ropes (commonly indicated with the term: sheets or halyards) suitably connected to the sails.
  • Winches essentially comprise a support body intended to be fixed onto the deck of the boat and a drum rotatably associated with the support body and intended to receive the windings of the line for manoeuvring the sail.
  • the drum is fitted coaxially onto the support body along a main shaft of the latter and is free to rotate with respect to the support body in a first direction of rotation (for example, in the clockwise direction), so as to wind the line on the drum, the drum being instead locked in the opposite direction of rotation. In this way, the drum transfers a traction force to the line during the operations under tension for recovering the line itself.
  • motorised winches are used.
  • the actuation force of the winch is supplied to the aforementioned main shaft by suitable motor means, typically electric or hydraulic, associated with the winch itself.
  • motor means typically electric or hydraulic, associated with the winch itself.
  • Such motor means are normally housed below deck and can be activated through hand or pedal switches located above deck.
  • winches with two speeds have been known and widely used.
  • Such winches make it possible to vary the ratio between the rotation speed imparted by the motor means to the main shaft of the winch and the rotation speed of the drum.
  • a long gear ratio or first speed, corresponding to a high rotation speed of the drum and to a low pulling action
  • a short gear ratio or second speed, corresponding to a low speed of the drum and to a high pulling action
  • Two-speed winches normally provides for a first gear ratio being operative when the actuation of the main shaft of the winch occurs in a first direction of rotation, and the second gear ratio being operative when the actuation of the aforementioned main shaft occurs in the opposite direction.
  • the change in gear ratio is thus obtained by simply changing the direction of rotation of the main shaft of the winch (it should be noted that the direction of rotation of the drum on which the line is wound still remains the same, any rotation in the opposite direction indeed being prevented).
  • two buttons, pedals or levers are typically provided on deck so that, when pressed, they activate a respective speed. Winches of this type are satisfactory in many applications.
  • the first speed is selected by inserting a speed variator (typically a speed reducer) (generally by pressing a button provided on the winch and one of the buttons provided on the deck of the boat) so that a long gear ratio (high recovery speed, low pulling action) is initially available.
  • a speed variator typically a speed reducer
  • the passage to an intermediate gear ratio (second speed, first inversion of the direction of rotation of the main shaft of the winch, lower rotation speed of the drum, greater pulling action) is obtained by pressing the other button provided on the deck of the boat; pressing this button also causes the speed variator to automatically be released.
  • the passage to a short gear ratio (third speed, second inversion of the direction of rotation of the main shaft of the winch, low rotation speed of the drum, high pulling action) is obtained by pressing the first button provided on the deck of the boat, the speed variator being still released.
  • the sizing or calibration (in terms of torque which can be delivered to the winch by the motor means and corresponding capability of the winch to bear traction loads on the line) of motorised multi-speed winches is carried out so as to deliver as maximum torque that force which is required to the winch to pull its maximum working load when the lowest speed is selected. This is the case that corresponds to the situation in which the line wound on the winch is subject to the maximum traction loads.
  • the Applicant has therefore felt the need to improve the performance of motorised winches with two or more speeds at the longer gear ratios, still keeping the necessary safety conditions that require that the winch be sized based upon the lowest speed, corresponding to the situation in which the line wound on the winch is subject to the maximum traction loads.
  • the invention therefore relates, in a first aspect thereof, to a control system for a motorised winch having two or more speeds, the motorised winch comprising a main motion input shaft, a drum for winding a line and a plurality of gears operatively arranged between the main shaft and the drum and adapted to define in the winch at least two different gear ratios, motor means being active on said main shaft for transmitting the motion to the winch, the control system being characterised in that it comprises detector means adapted to identify the gear ratio active in the winch and control means active on the motor means to adjust the torque and/or speed delivered by the motor means based upon the detected gear ratio.
  • control system devised by the Applicant allows, through detection of the gear ratio active on the winch, the torque and/or speed delivered by the motor means to be automatically increased when a long gear ratio is active in the winch (thus at the first speed, in the case of two-speed winches and at the first and second speed, in the case of three-speed winches) and allows no adjustment to be made to the motor means when a short gear ratio is active in the winch (for example, in two-speed winches, when the second speed is selected, and in three-speed winches, when the third speed is selected).
  • the performance of the winch at the longer gear ratios is improved, ensuring that it is possible to deliver to the winch a greater torque and/or speed than that which can be delivered to known winches with the same gear ratio, and thus allowing the winch, at such gear ratios, to bear a traction load on the line which is greater than that which can be borne, the gear ratio being equal, by known winches. All of this while still sizing the winch based upon the lowest speed, so as to remain in safe conditions.
  • the motor means can be electric or hydraulic.
  • the aforementioned plurality of gears is adapted to define in the winch a first gear ratio at which the drum of the winch rotates at a first speed and a second gear ratio at which the drum rotates at a second speed lower than the first speed.
  • the control means act on the motor means to increase the torque and/or speed delivered by the motor means when the first gear ratio is active in the winch.
  • the aforementioned plurality of gears is adapted to define in the winch a first gear ratio at which the drum rotates at a first speed, a second gear ratio at which the drum rotates at a second speed lower than the first speed, and a third gear ratio at which the drum rotates at a third speed lower than the second speed.
  • the control means act on the motor means to increase the torque and/or speed delivered by the motor means when the first or second gear ratio is active in the winch.
  • the control system of the present invention comprises actuation means which can be controlled to selectively activate a predetermined gear ratio in the winch.
  • Said actuation means preferably comprise at least one pair of pedal, button or lever elements (hereafter, for the sake of simplicity, indicated as: buttons) adapted to be activated to select a respective predetermined gear ratio.
  • the aforementioned actuation means also comprise a button mounted on the winch and intended to be activated to select a further predetermined gear ratio (typically through a speed variator).
  • the detection of the gear ratio active on the winch can occur in various ways and through different types of detector means.
  • the aforementioned detection can for example consist simply on detecting which of the two buttons is pressed, or the direction of rotation of the main shaft.
  • the aforementioned detection occurs by providing at least one speed sensor associated with the drum of the winch and at least one detection element associated with the motor means and adapted to detect a parameter which identifies the operating condition of the motor means.
  • a detection element preferably comprises a speed sensor associated with the motion output shaft of the motor means (such a shaft hereafter being called: drive shaft).
  • the aforementioned detection element can comprise a measuring device of the flow of fluid dispensed by the hydraulic motor (the flow and the pressure are indeed correlated to the speed of the drive shaft by a substantially linear relation).
  • the detection of the gear ratio active on the winch is carried out by providing at least one movement sensor associated with at least one gear of the plurality of gears, such a gear being in a condition of mechanical engagement when a first gear ratio is active in the winch and in a condition of mechanical disengagement when a different gear ratio is active in the winch.
  • this case exploits the fact that, in the passage from one gear ratio to another, some of the gears that are in an engaged condition when a first gear ratio is active in the winch are released when a different gear ratio is active in the winch.
  • the detection of the movement or otherwise of such gears thus allows the gear ratio active on the winch to be identified.
  • the detection of the gear ratio active on the winch occurs by also providing at least one proximity sensor associated with the button provided on the winch.
  • a proximity sensor associated with the button provided on the winch.
  • At least some of such sensors are of the wireless type, so as to avoid the presence of wires, which, particularly when associated to the rotary components of the winch, would be undesirable.
  • the present invention relates to a method for controlling a motorised winch having two or more speeds, the motorised winch comprising a main motion input shaft, a drum for winding the line and a plurality of gears operatively arranged between the main shaft and the drum and adapted to define in the winch at least two different gear ratios, motor means being active on said main shaft for transmitting the motion to the winch, such a method comprising the steps of:
  • such a method can be actuated by a control system of the type described above and thus allows all of the advantages described above with reference to the aforementioned control system to be achieved.

  • the drum 20 is fitted coaxially onto the support, along a main shaft 10 adapted to control the rotation (the longitudinal axis of which is indicated with X-X), through the interposition of a plurality of rolling bearings (not illustrated) adapted to allow the relative rotation of the drum 20 with respect to the support.
  • a rotation is imparted to the main shaft 10 of the winch 2 by the motor means 3 through a drive shaft 3a.
  • the rotation is then transferred to the drum 20, in a per sé known way, through a plurality of conventional gears (illustrated with a dashed line, in reduced number and absolutely schematically, only in figure 4 ).
  • the rotary body 20 is free to rotate with respect to the stator body in a single direction of rotation (for example in a clockwise direction of rotation), which corresponds to the winding direction of the line 100 onto the drum 20.
  • the drum 20 transfers to the line 100 a traction force which is suitable for overcoming the load T present on the line during the operations under tension for recovering the line itself.
  • the motor means 3 can be electric or hydraulic. Therefore, suitable electronic or hydraulic boxes (indicated with 5 in the attached figures) are provided to feed the motor means 3.
