Definitions
- the present invention relates to a device for rolling up/rolling down two shades (11, 12, 33, 34) to/from a respective rotatable tube (9, 10, 32), comprising a single drive motor (3), a transmission providing connection between said drive motor and each of said tubes (9, 10, 32), a coupling being provided between one of said tubes and said drive motor.
- Such a device is disclosed in the international patent application PCT/NL 02/00792 and provides a reliable functioning winding system for a shade, allowing accurately adjustment of the starting and end position and which can be effective during long time i.e. many years, without failure.
- the device described therein comprises a drive motor being fixedly connected to the frame. Between the drive motor and the tube a drive shaft is provided being rotatable by the drive motor, whilst on the drive shaft in the direction of its axis displaceable and non-rotatable relative to said frame a transmission device is provided connected to said tube for transmitting the rotating movement from the drive shaft to said tube.
- the improvement obtained results from the fact that no longer use is made of an expensive tube motor that is susceptible to damage and is difficult to install.
- a simple motor that is immovably connected to the frame is used instead.
- a drive shaft which will be fitted vertically in the case of vertically moving shading.
- the transmission device described above moves up or down in the vertical direction along this drive shaft. This vertical movement is imposed by the rolling up or rolling down of shading on the tube connected to the transmission device.
- This tube preferably extends in a direction perpendicular to the drive shaft.
- the invention aims to improve the device according to the invention such that a more flexible use and control is possible.
- said coupling comprises an electrically operatable clutch, which can be switched between an uncoupled and coupled position by operating means for said clutch, a control unit (55) being provided having an input for signals with regard to parameters of the surroundings, such as temperature, light, moisture, wind force and the like, and/or with regard to the condition of the shade, such as unrolled length and the like, for controlling said operating means.
- a control unit the shade can automatically be controlled in the desired mode. Both the conditions inside and outside the greenhouse can be taken into account.
- the device according to the invention can be used in any system, wherein at least two shades are operated by a single drive motor.
- control of at least one of said shades can be made independent of the movement of the drive motor.
- each of the shades is provided with its own electrically operatable coupling comprising a clutch.
- the device according to the invention comprises a system as disclosed in the international patent application PCT/NL 02/00792.
- the operating means can comprise memory means for storing data with regard to the position of the tube and/or the length of the unrolled tube dependent of values corresponding with data from the surroundings and/or the condition of the shade.
- a clutch that is effective when there is overloading i.e. an adjustable clutch
- the clutch becomes active, with the result that moment- limited disconnection of the roller tube relative to the drive shaft occurs.
- a braking feature between motor and tube in combination with the adjustable slip- action clutch, it is ensured that in the rolled-up position or in an intermediate position the roll-up tube does not roll out in an uncontrolled manner.
- a braking feature can be achieved with, for example a worm wheel.
- the output shaft of the transmission device is rigidly connected to the tube on which the shade is received, basically no guidance of the transmission device or support for receiving the rotational momentum is necessary. These forces can be received by the tube. It is possible to independently guide the transmission in other cases along the frame or greenhouse or the like.
- the device described above for rolling up and rolling down shades can also be used in the case of a so-called twin shade, i.e. a tube on which two shades are rolled on top of each other.
- twin shade i.e. a tube on which two shades are rolled on top of each other.
- One of these shades is connected in the manner described above to an immovable fastening situated above it, while the other shade has a weighted free end and extends hanging downwards.
- the device can comprise at least a further shade having a further inmovable top fastening and a further rotatable tube that is movable in said frame construction, for receiving and unwinding shade and a further transmission device movable on said drive shaft in the direction of its axis and not rotatable relative to said drive shaft for transmitting the rotating movement from said drive shaft to said further tube, said further transmission device being provided with a further clutch.
- a further shade having a further inmovable top fastening and a further rotatable tube that is movable in said frame construction, for receiving and unwinding shade and a further transmission device movable on said drive shaft in the direction of its axis and not rotatable relative to said drive shaft for transmitting the rotating movement from said drive shaft to said further tube, said further transmission device being provided with a further clutch.
- These devices may be situated between horizontal trusses of, for example, a glasshouse.
- the clutch described above and operating means to be fitted for it, such as stops it is possible during rotation of the drive shaft to make each transmission device, and consequently each shade, perform exactly the right movement, without overloading occurring.
- This means that a large number of tubes on which shading is wound can be operated by means of a single motor.
- at least one further drive shaft can be operated by means of the single motor.
- the invention also relates to a method for operating a device according to one of the preceding claims comprising the steps of: determining the value of a surrounding parameter such as temperature, light, moisture, wind strength, time and the like, selecting based on this value(s) a position of the tube and/or the length of the unrolled shade, energizing the drive for rotating of the tube for unrolling or rolling the shade, energizing the operating means for slippage of the slip clutch when the desired position of the tube, and/or the desired length of the unrolled shade is reached.
- a surrounding parameter such as temperature, light, moisture, wind strength, time and the like
- the method also relates to energizing of other operating means for slipping of further slip clutches when the desired position of the further tube and/or the desired length of the unrolled further shade has been reached.
- Fig. 1 shows diagrammatically in elevation a part of a glasshouse construction provided with the assembly as described in PCT/NL02/00792;
- Fig. 2 shows a detail of the transmission device according to Fig. 1;
- Fig. 3 shows a cross section along the line III-III in Fig. 2; and
- Fig. 4 shows a variant of the shade according to the invention illustrated diagrammatically
- Fig. 5 a view of the device according to the invention.
- Fig. 6 a plan view, partially in cross section, of a transmission as used in the device according to fig. 5 and according to line VI- VI in fig. 7;
- Fig. 7 a front view, partially in cross section, of a transmission as shown in fig. 6;
- Fig. 8 a side view of the transmission as such.
- the frame of the glasshouse is shown diagrammatically by 2. It is easily possible to use a separate frame for the construction according to the invention, but in the case of a glasshouse this was not found to be necessary.
- a motor 3 is immovably fastened to the frame construction 2.
- the auxiliary shaft 4 is present, and a substantially vertically extending drive shaft 6 is driven by way of a right-angled transmission 5.
- the drive shaft 6 extends through transmission devices 7 and 8 respectively, by means of which tubes 9 and 10 respectively are driven, for the purpose of moving shades 11 and 12 respectively. Stops 13 and 14, which can interact with the operating means 25 and 26 respectively shown in Fig. 2, are present.
- the abovementioned shades 11 and 12 are illustrated- in Fig. 1 by a solid line to the right of the vertical section 28. It will be understood that shades may also be present to the left of said section, as partially shown.
- transmission devices 7 and 8 Details of the transmission devices 7 and 8 respectively are shown in Figures 2 and 3. It can be seen from these figures that shaft 6 is provided with a groove 15 extending along its entire length.
- the transmission device is composed of a box 17, which by way of a guide 29 (see Fig. 3) can be slid along its own drive (shaft 6) and the vertical T-section 28 of the frame construction 2.
- a sleeve 21 is provided, which, as can be seen from Fig. 3, is provided with a key-shaped projection 18, which means that sleeve 21 is not rotatable, but is slidable, relative to drive shaft 6.
- Sleeve 21 is provided with a(n) (adjustable) slip-action clutch 23, fitted corresponding to tooth system 24 on gear sleeve 16.
- tooth system 23 is driven to tooth system 24, so that the rotary movement applied to sleeve 21 can be transmitted to gear sleeve 16. If, however, the load is too great, tooth systems 23 and 24 will move past each other and slip will occur.
- the moment of slip can be regulated by adjusting initial tension in the spring. It will be understood that slip or disconnection can be achieved in another way.
- the clutch formed in this way is indicated by 20.
- the clutch 20 described above will also function, so that no damage is caused to the shades or drive.
- the clutch 20 also prevents further rotation of tubes 9 and 10 if tube 6 is brought to a standstill in a position before a stop.
- a so-called twin shade is shown diagrammatically in Fig. 4.
- a central tube 32, on which a double shade is wound, is present. This is indicated by 33 and 34.
- Shade 33 extends upwards and is immovably fastened to the frame construction 2, like the shades 11 and 12.
- Shade 34 is provided with a weighted end, indicated by 35, which end is free, i.e. if desired moves upwards and downwards by way of a guide, by gravity.
- Tube 32 can be put in the place of tube 9 or 10. The same effect can be obtained in this way.
- the arm 40 can be operated through both solenoids 52, 53.
- the solenoids 52, 53 operate a shaft 54 extending there between, which is connected itself with the arm 40.
- the shaft 54 By operating one or both solenoids 52, 53, the shaft 54 and so the arm 40 is tilted.
- the tube 9, 10 can be stopped in any desired height.
- the other tubes 9, 10 can continue to move or also be stopped depending from the control program.
- the tubes 9, 10 are axially displaceable but unrotatably connected with the shaft studs 56 for compensate differences in expansion.
- This control can be controlled by the control unit 55 as shown in fig. 5.
- signals can be fed, relating to the outer surroundings or both the outer and inner conditions of the greenhouse in which the device according to the invention is used. It can relate to temperature, moisture, direction of wind, light and the like.
- signals can be fed to the control unit 55 with regard to the position of the tubes 9, 10, the position of the transmissions, i.e. whether or not they are in a slipping or non-slipping condition and the like.
- the control unit can subsequently control the motor 3 as well feed signals to the solenoids 52, 53. In this way the tubes 9, 10 can be adjusted on any desired height independent from each other. Associated therewith the shades 11, 12 can be unwinded or winded at any desired length independent from each other.
