Definitions

  • THE PRESENT INVENTION relates to a dispensing arrangement and more particularly relates to a hand-held dispensing arrangement for dispensing a multi-part reactive mixture.
  • a two-part adhesive or sealant is formed by mixing together two liquid components which react together to provide the adhesive or sealant.
  • the individual components may be stored over a long period of time without deteriorating significantly.
  • the components react together and an adhesive or sealant having the appropriate properties is created.
  • the adhesive or sealant may cure or set due to the chemical reaction between the two components over a relatively brief period of time.
  • the hand-held apparatus comprises a frame to which is connected a hand-hold and "trigger".
  • the frame supports a cartridge which contains, in two separated chambers, the two components which are to be mixed together.
  • the trigger drives separate pistons into the two chambers forcing the liquid components out of the chambers through an outlet port.
  • a mixer which may be a so-called static mixer, is connected to the outlet port.
  • Arrangements of this type have operated satisfactorily for many years, but they do have some disadvantages.
  • One disadvantage is that the cartridge can only contain a predetermined relatively small quantity of each of the two liquids. The cartridge may become exhausted relatively quickly, requiring replacement of the cartridge. When a cartridge is replaced the old cartridge has to be disposed of. Thus the manufacture, filling, transportation and eventual disposal of cartridge adds substantially to the overall cost of the operation. The cost can be prohibitive if the hand-held dispenser is being used in a "factory" situation, with substantial quantities of adhesive being dispensed each day.
  • the present invention seeks to provide an improved liquid dispenser.
  • a dispensing arrangement for dispensing a two-component mixture
  • the dispensing arrangement comprising a hand-held unit having at least one handle, the unit incorporating two metering devices, each metering device being provided with an inlet to be connected to a source of liquid under pressure, each metering device having an outlet for metered quantities of liquid, the unit further incorporating flow passages which extend to an outlet port connected to a mixer, there being a mixer connected to the outlet port to mix the two metered liquids and to dispense the mixed liquids.
  • the handle of the unit is associated with a control trigger.
  • the handle is located beneath the unit.
  • the handle is located above the unit.
  • two handles are provided, the handles being provided on opposed sides of the unit.
  • the unit is suspended on a support which applies an up-thrust to the unit substantially equal to the force applied to the unit by gravity.
  • each metering device is connected to a respective source of pressurised liquid.
  • each source of pressurised liquid is a main supply of pressurised liquid capable of supplying a plurality of dispensing devices.
  • the mixer is a static mixer.
  • each metering device incorporates an elongate chamber there being a shuttle contained within the chamber, the shuttle having a portion which is a substantially sealing sliding fit within the chamber, the shuttle being moveable axially between an initial position and a second position within the chamber, each end of the chamber being provided with a liquid flow duct through which pressured liquid may enter and leave the chamber, there being valve arrangement to control the flow of liquid to and from the chamber such that, during successive cycles of operation of the metering device, liquid is supplied to one end of the chamber causing the shuttle to move from the initial position at said one end of the chamber to the second position at the other end of the chamber, thus ejecting a pre- determined volume of liquid from the other end of the chamber, and subsequently liquid is supplied to said other end of the chamber causing the shuttle to move back from the second position to the initial position, ejecting a pre-determined quantity of liquid from the said one end of the chamber, the valving means comprising a rotary valve rod contained within a valve bore, and a
  • each valve rod is rotated by a motor arrangement, the motor arrangement being controlled in response to a signal generated in response to the shuttle of the other metering device reaching an initial position or the second position.
  • each motor arrangement is a stepping motor.
  • the shuttle is provided with two rods, each rod extending beyond the chamber, there being a contact or proximity sensor located at the end of each rod, to generate a said signal when the shuttle reaches the initial position or the second position.
  • adjustable collars are provided on the shuttle rods to limit the movement of the shuttle.
  • at least one air bleed is provided communicating with part of each chamber to bleed air from the chamber.

  • FIGURE 6 is a view of the dispenser arrangement of Figure 5 when assembled
  • FIGURE 7 is a view of a modified form of liquid dispenser arrangement
  • FIGURE 8 is a view of a further modified form of liquid dispenser arrangement.
  • the shuttle 3 is a unit or assembly which has a central cylindrical portion 4 which is a sliding sealing fit with the chamber 2.
  • the shuttle incorporates two rods 5,6 which extend axially from opposite sides of the cylindrical portion 4 and which pass, as a sliding sealing fit through apertures formed in the end walls of the chamber 2, the rods 5,6 thus projecting beyond the housing.
  • adjustable collars 7,8 Mounted on the projecting portions of the rods 5,6 are adjustable collars 7,8, the position of which may be adjusted to alter the "stroke" of the metering device as will become clear from the following description.
  • sensors 9,10 Located adjacent the ends of the rods 5,6 are sensors 9,10 which are responsive to the rods 5,6 each reaching a pre- determined position. The sensors may, ideally, be responsive to physical contact of the end of the rod with the sensor.
  • the central cylindrical portion 4 of the shuttle effectively divides the chamber 2 into two separate parts, one at the left-hand end of the chamber and the other at the right-hand end of the chamber.
  • Respective liquid flow ducts 11 ,12 connect these end parts of the chamber 2 to spaced-apart points of a cylindrical valve bore 13 defined within the housing 1.
  • Outlet and inlet ducting also communicate with the bore 13.
  • the housing defines a first outlet flow duct 14 offset from the flow duct 11 and second outlet flow duct 15 offset from the flow duct 12.
  • the outlet flow ducts 14 and 15 are off-set axially from the flow ducts 11 and 12, being closer to the ends of the valve bore 13, but one diametrically opposed to the flow ducts 11 ,12.
  • a liquid inlet flow duct 16 is also defined located at a position between the two liquid flow ducts 11,12.
  • Contained within the cylindrical valve bore 13 is a rotary valve rod 17 which is driven rotationally by a stepping motor M in response to signals from the sensors 9,10.
  • the rotary valve rod 17 has parts thereof cut away in the form of a channel or recess in the periphery of the rod and passages or bores through the rod so that the rotary valve rod 17, in the cylindrical valve bore 13, may define liquid flow paths.
  • the rotary valve rod 17 is provided with a first through bore 18 which is inclined to the axis of the valve rod 17 and which, in one rotational position of the valve rod 17, when the valve rod 17 is present in the bore, serves to interconnect the liquid flow duct 11 and the first outlet flow duct 14.
  • a second corresponding bore 19 is provided, parallel with the first bore 18, the second bore 19, as will be understood from Figure 2, in an alternate rotational position of the valve rod 17, serves to interconnect the liquid flow duct 12 and the second outlet flow duct 15.
  • the groove 20 is provided with two diametrically opposed axial extensions 21 ,22, which extend in opposite axial directions.
  • the shuttle 3 is shown in a right-hand most position with the end of the projecting shuttle rod 6 engaging the sensor 10. As the shuttle rod 6 contacts the sensor 10, so the stepping motor M rotates the valve rod 17 by 180°, thus moving the valve rod 17 to the position as shown in Figure 4.
  • the groove 20 and the axial extension 21 serve to connect the inlet 16 to the liquid flow duct 12 which communicates with the right-hand end of the chamber 2, whereas the bore 18 serves to interconnect the liquid flow duct 11 (which, in turn, communicates with the left-hand end of the chamber 2), and the outlet flow duct 14.
  • Pressured liquid may thus flow from the inlet flow duct 16 through the annular groove 20 and the axial extension 21, through the liquid flow duct 12 into the right-hand end of the chamber 2 thus serving to move the shuttle 3 towards the left.
  • the shuttle 3 moves towards the left, so liquid in the right-hand end of the chamber is discharged through the liquid flow duct 11 , and the bore 18 and through the outlet 14.
  • the shuttle 3 thus continues to move towards the left until the shuttle rod 5 contacts sensor 9.
  • the shuttle 3 has completed its stroke and a pre-determined quantity of liquid in the form of a metered "shot" of liquid has been ejected through the outlet flow duct 14.
  • the stepping motor M again rotates the valve rod 17 by 180°, thus returning the valve rod 17 to the position or orientation shown in Figure 3.
  • liquid will flow from the inlet through the annular groove 20, the axial extension 22, and through the liquid flow duct 11 to the left-hand end of the chamber 2.
  • the bore 19 in the valve rod 17 interconnects the liquid flow duct 12 and the outlet 15, allowing liquid from the right-hand end of the chamber to flow to the outlet 15.
  • the shuttle 3 will move towards the right until the shuttle rod 6 establishes contact with the sensor 10.
  • the stepping motor M only rotates the valve rod 17 on receipt of a signal from the sensor 9, or the sensor 10, if the shuttle 3 is not able to complete its stroke, for example due to a lack of liquid, or insufficient liquid pressure, no signal will be given and the metering unit will cease operation. In this way it can be ensured that for each cycle of operation the metering unit delivers an appropriate quantity of liquid, in the form of a correctly metered "shot", which can be of crucial importance if two liquids, which are components of, for example, a two-part adhesive or the like, are to be metered by two separate metering units and mixed in a precisely pre-determined ratio, relative to each other.
  • the position of the collars 7,8 on rods 5,6 may be adjusted and the position of the sensors 9,10 may be adjusted to increase or decrease the stroke of the shuttle, thus increasing or decreasing the quantity of liquid ejected on each stroke of the shuttle.
  • the chamber 2 may be provided on either side of the cylindrical portion 4 of the shuttle 3, with air bleeds 23, 24. These may be opened to permit air to be discharged from the chamber 2, especially when the described metering device is first filled with the liquid to be metered, to ensure that hydraulic integrity can be established with no compressible air remaining in the chamber 2.
  • the valve is a rotary valve rod, which facilitates manufacture and maintenance of the valve.
  • the valve rod may rotate almost uniformly, avoiding sudden changes of momentum as maybe experienced with a reciprocating valve.
  • the metering device as described may be "reversed", with pressurised liquid being supplied to the "outlets" 14,15, and with the "inlet” 16 actually acting as an outlet.
  • sensors 9, 10 responsive to contact with the shuttle rods
  • proximity sensors which respond to the shuttle rods reaching predetermined positions may be used.
  • the sensors 9,10 may be annular, with the rods 5 and 6 passing through the sensors, with the sensors 9,10 providing an output signal when contacted by the collars 7 and 8.
  • Figure 5 illustrates an exploded view of one embodiment of the invention.
  • Figure 5 illustrates a hand-held dispenser 30 in an exploded form.
  • the hand-held dispenser comprises a support plate 31 of square or rectangular form.
  • a handle 32 is connected to the under-surface of the support plate 31 , the handle 32 being provided with a finger operated trigger 33.
  • Mounted on top of the support plate are two metering devices 34, 35 of the type described above.
  • the metering devices are provided with inlet ports (not shown) which are configured to be connected to supply conduits 36, 37. As will be described hereinafter the supply conduits may extend to a "main" supply of pressurised liquid.
  • the metering units 34, 35 have outlet ports 38, 39 formed in their upper surfaces. Clampingly engaging the upper surfaces of the metering devices 34, 35 is a liquid transfer housing 40.
  • the housing 40 has two internal passages each of which extend from a point immediately above respective outlets 38, 39 of a metering device, to a combined outlet 42.
  • a plate 43 with a screw-threaded boss 44 is secured to the end wall of the housing 40 adjacent the combined outlet 42.
  • a conventional static mixer 45 as shown in EP 0105181 is secured, by means of a internally threaded collar 46, to the threaded boss 44, so that the mixer is in liquid flow communication with the combined outlet 42.
  • a motor housing M containing the motors that drive the pumps, and the control for the motors, extends to the rear of the arrangement.
  • the fully assembled liquid dispenser 30, as shown in Figure 6, may be suspended, by means of a wire or cable 47 connected to the upper part of the housing, from a support mechanism 48 which includes a resilient retractor.
  • the effect of the retractor is to provide an upward force to the dispenser 30 which is equivalent to the downward force applied by gravity. This facilitates manual operation of the dispenser.
  • conduit 36 is connected to a "main" supply conduit 49 and the conduit 37 is connected to a "main” supply conduit 50.
  • main supply conduits 49, 50 which are connected to pressurised sources of the appropriate liquids.
  • a large number of hand-held dispensers of the type being described may thus be used within the factory, all being connected to a common supply. This avoids the need for individual drums of the appropriate liquids to be located adjacent each dispenser, and facilitates the provision of the two reactive liquids to a large number of dispensing devices.
  • an operative will locate the end of the static mixer 45 at a point where the two-component mixture, such as an adhesive or a sealant, is to be dispensed.
  • the trigger is depressed, which actuates the metering devices 34, 35.
  • the metering devices 34, 35 are controlled by a common controller, which may be located within the housing 40. The controller operates so that the shuttle within the metering device 34 must initially complete a stroke and send a signal to the controller before the valve in the metering device 35 is moved to cause the shuttle in the metering device 35 to complete a stroke.
  • the controller When the shuttle in the metering device 35 has completed a stroke, the controller then actuates the motor of the metering device 34, changing the position of the valve within the metering device 34, so that the shuttle in the device 34 may complete a stroke.
  • the two metering devices thus work sequentially, and should the shuttle of either metering device fail to complete a stroke, the entire apparatus will stop.
  • the liquid from the metering device 34 flows through the outlet 38 and through the housing 40 to the outlet aperture 42.
  • liquid from the metering device 35 flows through the outlet 39, through the housing 40 to the outlet aperture 42.
  • the two liquids thus pass through the threaded boss 44 and into the static mixer 45.
  • the liquids are mixed within the static mixer and are dispensed.
  • the liquid within the static mixer will only be partly reacted when dispensed, and thus the adhesive or sealant will have adequate properties. Should there be a long delay between operations of the device the liquid within the static mixer may react and set or cure within the mixer. Should this happen, the static mixer is simply removed from the threaded boss 44 and a further static mixer is provided.
  • the device may be removed from the supply lines 36, 37 and may be replaced by a fresh device, whilst the malfunctioning device is serviced or repaired.
  • a handle may be provided on each side of the device, such as handles equivalent to the handle 51 shown in a modified embodiment as illustrated in Figure 7.
