Definitions

  • This invention relates to a dispenser particularly adapted to dispense liquids, powders, solids, slurries or material in any other non-gaseous state from a container of such material.
  • the apparatus of the present invention may be used for dispensing detergents or any other material in an industrial or commercial process.
  • the invention is particularly adapted, however, for the dispensing of detergents, rinsing aids and water softener materials to commercial dishwashing and laundry machines.
  • the invention will be described in connection with the dispensing of such materials in commercial dishwashing machines.
  • dIspensing apparatus Many forms of dIspensing apparatus are known.
  • a container of the powder is affixed to a dIspensing head, typically by using an external screw thread on the container to engage within an internal thread on the dispensing head.
  • Water is supplied to the dispensing head under pressure to spray, jet or otherwise enter the container in a stream which either dissolves some of the detergent powder or forms a slurry therewith.
  • Such slurry or dissolved powder is forced from the container through an outlet in the dispensing head and is conveyed by an appropriate pipe, hose or the like to the end use location, such as the dishwasher.
  • the container is full of water. To replace the container, it must be unscrewed from the dispensing head and this can result in spillage of water from the container. While such water is substantially diluted, it will still contain some dissolved detergent and any spillage is undesirable and may be dangerous.
  • the container of detergent is inverted over a water inlet.
  • the detergent in the container may be in solid form, in which case a water jet is used to dissolve a predetermined amount of detergent for use, or in powder form, in which case a fine mesh screen or the like is used to hold the powder in the container while it is inverted.
  • the powder is dissolved by a jet of water directed into the container through the filter.
  • US-A-2079049 discloses a dispensing apparatus according to the preamble of claim 1.
  • a tube and an annular flange support a cylindrical gasket against the expanding element.
  • the expanding element is initially locked against movement relative to the annular flange by a pair of screws. When the screws are removed, a spring biases the expanding element away from the flange, causing the gasket to be compressed axially and to expand radially.
  • a dispensing apparatus comprising a dispensing head having a dispensing fluid inlet passage communicating with a fluid delivery means, a fluid outlet passage, both inlet and outlet passages passing through an expanding member of a container mounting, said expanding member mounted substantially coaxially with a flexible, resilient seal member, a stem on said expanding member, a seal carrier for the seal member mounted to a housing characterized in that said seal member is mounted for pivotal movement relative to the housing, and moving means is operatively associated with the stem to move the expanding member axially relative to the seal member to releasably secure a container to the container mounting when the seal carrier is pivotally moved relative to said housing with the inlet and outlet passages adapted to communicate with the container interior.
  • the expanding member has a tapering surface which, on relative movement, contacts and expands the seal member.
  • the outer end of the expanding member tapers inwardly to facilitate engagement of a container with the container mounting.
  • the expanding member is formed of a rubber, synthetic rubber or synthetic plastic material, the seal being adapted to engage within a top or neck of a container which holds material to be dispensed, with the expanding member disposed within the container. Relative movement of the expanding member and the seal member causes engagement and outward expansion of the seal into sealing engagement with the container top or neck, depending on the size and type of container used.
  • the carrier for the seal member is pivotally located on a mounting support to permit pivotal movement of the container mounting.
  • the expanding member extends through the carrier and is provided with a circlip which forms a shoulder for a spring mounted between the carrier and the circlip. The spring urges the expanding member into expanding engagement with the seal member.
  • the upper end of the expanding member is provided with a cam follower, preferably in the form of a roller, which engages with a cam surface located adjacent the mounting support.
  • the cam surface is disposed so that pivotal movement of the container mounting causes relative movement between the expanding member and the seal member.
  • a detent is provided in the cam surface to retain the carrier mounting in a position in which the biassing spring is compressed and the expanding member has bee moved away from expanding engagement with the seal member. In this position, the outlet opening, or neck, of a container is able to engage over the expanding member and seal member so that reverse pivotal movement causes the seal member to be expanded within the mouth of the container.
  • the invention is applicable to a fluid dispensing system in which water is pumped into a container of material to be dispensed such as detergent, and the resultant solution or slurry passes out of the container for use.
  • resultant solution or slurry is pumped out of the container so that there is no buildup of fluid within the container.
  • the container is substantially empty, thus minimizing the risk of spillage during removal.
  • the water pumped into the container can be used to pressurize the container which forces the resultant solution or slurry through the fluid outlet passage.
  • the dispensing fluid inlet passage and outlet passage comprise or include electrodes adapted to be used to sense if the level of water in the container exceeds a predetermined level indicating a fault in the dispensing apparatus.
  • both inlet and outlet passages comprise metal tubes which extend a predetermined distance into the container, and appropriate electrical measuring circuits are used to detect if the level of fluid in the container reaches the electrodes.
  • the material being dispensed is a liquid
  • the liquid material may be simply dispensed by pumping from the liquid container.
  • a relief valve will be provided in the dispensing head to permit air to enter the container on removal of liquid therefrom. This relief valve constitutes the fluid inlet passage.
  • a dispensing system for dispensing solid, powder, liquid or other material from a container
  • at least one dispensing module having a dispensing head with a fluid delivery means communicating with a fluid inlet passage, a fluid outlet passage, both inlet and outlet passages extending through a container seal carrier having an internally expandable sealing member to sealingly engage within a neck of the container, said sealing member having a deformable member, deforming means selectively movable axially relative to said seal carrier to cause the sealing member to deform and so engage the container neck
  • said seal carrier includes pivot means, a relatively movable stem through which the inlet and outlet passages pass, and cam means associated with the stem, the cam means being operable on pivotal movement of the seal carrier to effect expanding or contracting of the sealing member.
  • the system includes two or more dispensing modules each connected to a fluid reservoir, a control module connected to each dispensing module, and pumps to supply fluid to the inlet passages.
  • Figure 1 illustrates a form of dispensing apparatus in accordance with the invention wherein two detergent powder dispensers 112, a rinse aid dispenser and a control module 116 are mounted in an assembly.
  • Each of the detergent dispensers 112 has a dispensing head 117 ( Figure 2) and is connected to a fluid supply pump (not shown) mounted in the control module 116.
  • a fluid reservoir, also located in the control module 116 is connected to a water supply system through a ball valve or similar control system and the fluid supply pump supplies water from the reservoir to each of the detergent dispensers 112, as determined by the requirements of the system which are pre-programmed into control circuits operated by the control module 116.
  • the dispensers 112 may also be connected to a solution delivering pump (not shown) located in the control module 116 for delivery of solution from either of the dispensers, or both.
  • a further delivery pump may also be provided for delivery of liquid rinse aid from the rinse aid dispenser 114.
  • Both the detergent dispensers 112 and the rinse aid dispenser 114 have lift-up lids 118 permitting access to the respective dispensing heads 117.
  • Each dispensing head 117 comprises a seal carrier 122 pivoted to the body 124 of the dispenser 112 by pivot pins 123 engaged in appropriate pivotal supports (not shown).
  • the seal carrier 122 supports a seal member 121 which has a radial flange 121a engaged within a circumferential recess 120 in the seal carrier 122.
  • An expanding member 119 passes through the bore of the seal member 121.
  • the upper end of the expanding member 119 carries a cam roller 127 which is adapted to engage with a cam surface 126 formed on the body 124 of the dispenser 112.
  • the lower end of the expanding member is formed with a shape of two opposed, truncated cones which provides a tapered, expanding surface 137 adapted to engage with an inner surface of the seal member 121 to thereby expand the seal member upon relative movement of the seal member and the expanding member 119.
  • the lower tapered surface 138 of the expanding member provides a guide surface for the engagement of the mouth of a container 133 with the seal member 21.
  • the expanding member 119 is provided with a circlip 139, and a compression spring 141 engages between an upper surface of the seal carrier 122 and the circlip 139 to bias the expanding member into expanding engagement with the seal member 121.
  • a fluid inlet tube 128 and a solution outlet tube 129 sealingly engage, and pass through the expanding member 119 to provide communication between the fluid supply pump and solution outlet or delivery pump and the interior of a container 133 engaged wit the dispensing head 117.
  • Flexible inlet and outlet pipes 131 and 132 connect with the inlet and outlet tubes 128 and 129, respectively, while, at their lower end, the inlet and outlet tubes 128 and 129 may be connected to flexible tubes 134 and 136 disposed within the container and which are able to follow the level of powder within the container during the dispensing thereof over a period of time.
  • a container 133 which contains detergent is formed with a neck at the mouth 142 of the container which is adapted to engage over the seal member 121 when the expanding member is in the lowermost, disengaged position.
  • This position is achieved by rotation of the seal carrier 122 about the axis of the pivot pins 123 so that the cam roller 127 moves along the cam surface 126 thus compressing the spring 141 and causing the expanding member 5 move downwardly relative to the seal member 121.
  • the cam surface 126 is preferably in the form of rail, rib or similar structure and the cam roller 127 is flanged to positively engage with the cam surface 126.
  • a detent 142 in the cam surface holds the cam roller 127 at the disengaged position and maintains the seal carrier 122 at an appropriate angular relationship which enables the mouth 142 of a container 133 to be engaged with, or disengaged from the seal member 121.
  • the shape of the lower surface 138 of the expanding member 119 facilitates guiding of the container mouth 142 into the appropriate position.
  • the inlet and outlet tubes 128 and 129 enable water to be pumped into the container 133 and slurry or solution to be dIscharged or pumped therefrom, as determined by the pre-programmed control system. If, as a result of a fault in the pumping system, the water level in the container 133 rises beyond a predetermined level, electrodes which are attached to or comprise the inlet and outlet tubes 128 and 129 sense the high water level and deactivate the pumping system. An appropriate audible and/or visual alarm may also be initiated on the control panel 116. As this dispensing system incorporates two detergent dIspensers 112, the malfunction of one dispenser can automatically initiate operation of the second dispenser.
  • the tilt action of the dispensing apparatus of this embodiment enables quick, easy and safe removal and replacement of containers of detergent powder, or other material, in the dispensing apparatus.
  • the lift-up lids 118 which may be of a transparent plastic material, can provide additional safety by preventing actuation of a dispenser while the lid is in the raised position and by providing a physical shield between the dispensing head and the face and body of an operator.
  • the container 133 does not need to be pressurized and, therefore, most commercial forms of containers having relatively standard mouth dimensions may be used with the apparatus of the invention.
  • the invention is not limited to apparatus with pump removal of the solution or slurry of detergent and the invention is equally applicable to other forms of solution removal, such as by pressurizing the container.
  • the control module 116 of the dispensing apparatus preferably includes microprocessor control pre-programmed to effect the desired operational control of the apparatus. This will include control of pump motors (when used), temperature sensing, conductivity sensing, input signal sensing (from the dishwashing machine(s) with which the apparatus is associated) and bar code readers or sensors 144. These readers or sensors 144 are located on each dispenser 112 and 114 in front of each container 133, and the containers 133 are provided with an appropriate bar coding (not shown) which identifies the nature of the product in the container. Thus, a detergent will have a pre-assigned code while a rinse aid will have a different code.
  • the control module 116 is programmed to permit operation of the apparatus only when the correct containers are located in the correct positions in the apparatus. Thus, if by an error, a rinse aid container is located in a position occupied normally by a detergent container, the bar code reader senses the error and prevents operation of the apparatus.
  • the bar code readers sense the absence of a container from any location to prevent the operation either of the apparatus as a whole or, preferably, of the particular station from which the container has been removed.
  • control module 116 may be provided in the control module 116 including alpha/numeric displays, indicator fights and the like. Provision may be provided for remote programing of the microprocessor.
  • control module 116 will monitor inputs from the dishwashing machine waiting for a machine cycle to commence. If the control system senses a product bar code on a container does not match the programmed container positions then the control display will indicate the incorrect bottle position and will prevent actuation of the system. A reset button may be provided to recommence the control operation.
  • control module 116 When the water fill line from a machine becomes active, the control module 116 will begin to dose the machine with the appropriate chemical. A timer is actuated to detect if the process of reaching the desired conductivity, determining chemical concentration, exceeds a predetermined maximum. The chemical is then dispensed to the machine by a detergent pump, the appropriate amount of detergent being a predetermined measure.
  • the system will generally choose one of the detergent containers before the other from which to dispense detergent. However, if that container is empty, as measured by the conductivity measurements taken through the inlet/outlet tubes, the machine automatically switches to dispense detergent from the other container.
  • a pushbutton may be used to manually flush a container which is indicated as being empty of detergent.
  • the flush button is operable only when the system has detected that a container is exhausted, and will only run the flush pump for as long as the flush button is pushed.
