  • a plurality of fluids such as (components of) paints, paint colorants, hair dyes, shampoos, foundations, and the like. It can be used for dispensing numerous recipes of the said products and can be located e.g. at a retailer of decorative paints, a hairdresser, or a spa, respectively.
  • This particular dispensing apparatus 1 is an automated version and includes a horizontal turntable 2, with a plurality of containers 4 and piston pumps 3 mounted along its circumference.
  • the turntable 2 can be rotated between discrete positions, e.g. sixteen positions including a dispensing position.
  • the apparatus 1 includes a frame 5 of e.g. aluminium extrusion profiles on which sheets (not shown) of metal or a polymer (transparent, translucent or opaque) can be attached by means of e.g. screws.
  • a control panel comprising a display and a small keyboard for entering information, such as customer data and recipes, is typically mounted on one side of the frame 5, next to a door or front section 6.
  • This front section 6 contains a computer (not shown) for storing the said information and for driving the turntable 2 and actuators for operating the pumps 3, as will be explained in more detail with reference to Figure 3 .
  • the pumps 3, shown in more detail in Figure 2A are known in the art and comprise, at least in this example, a cylinder 10 and a piston, mounted inside the cylinder 10 and provided with a piston rod 11, which, on its upper end, is provided with a washer or flange 12.
  • the cylinder 10 is mounted in the top part of a pump housing 13, containing a known valve member, e.g. a disc, ball or cylinderal valve, which can be operated by means of a lever 14.
  • a known valve member e.g. a disc, ball or cylinderal valve
  • the cylinder 10 communicates with a container 4 and can be filled with a desired amount of the fluid from the container 4 by moving the flange 12 and thus the piston upwards over a desired or predetermined length.
  • the valve member can be rotated to a open position. In this position, the cylinder 10 communicates with a dispensing opening in the bottom surface of the pump housing 13 and the fluid can be dispensed by moving the flange 12 downwards.
  • Each of the containers 4 comprises a stirrer having a shaft rotatably mounted in the bottom wall of the respective container 4.
  • the section of the shaft that is inside the container 4 (and thus hidden from view) comprises stirring elements, such as blades or rods shaped to encompass a substantial part of the volume of the respective container.
  • the end of the shaft is provided with a hook 20 to be engaged by a drive mechanism 21, shown in Figures 2A to 2C , attached to the frame 5 of the apparatus 1 and located, in this example, one or more, e.g. three positions away from the dispensing position.
  • the drive mechanism 21 comprises an electric motor 22, a housing 23 accommodating a rotatable element (hidden from view), e.g. e friction disc or (semi)circular rack, coupled to the shaft of the electric motor 22.
  • the mechanism 21 further comprises a lid 24 resilient pressed onto the upper rim of the housing 23 by means of a screw 25 and a spring washer rotatably attached to e.g. the rotatable element.
  • a cam 26 is pivotally mounted in the lid 24 and engages the rotatable element, e.g. by means of a curved friction surface or teeth. When the rotatable element is driven in the clockwise direction (in the embodiment in the figures and in top view), the cam 26 is rotated about 90 degrees and thus extended from the lid 24.
  • the cam 26 couples the lid 24 to the rotatable element and the lid 24 and the extended cam 26 start rotating, while the housing 23 remains stationary.
  • the cam 26 will engage the hook 20 of the stirrer of the container 4 above it and will thus stir the contents of the container 4.
  • the rotatable element is driven in the counter-clockwise direction and the cam 26 is rotated about 90 degrees in opposite direction and thus retracted.
  • actuators 30, 31 for, respectively, the valve and the piston of the pumps are located on the inside of the front section 6.
  • the actuator 31 for the piston comprises and electric motor 32, a lead screw 33 formed on or rigidly connected to the shaft 34 of the electric motor 32, and a gripper 35.
  • the gripper 35 is shaped like a claw, which allows unobstructed horizontal movement of the pumps 3, but engages, when it moves vertically, the flange 12 and hence the piston of the pump 3 in front of it, i.e. the pump 3 at the dispensing position.
  • the gripper 35 is mounted on the lead screw by means of a nut or internal thread, i.e.
  • the gripper 35 slidingly abuts a surface of the apparatus 1, in this example the inner wall of the front section 6, which surface extends parallel to the lead screw 3.
  • the width of the side of the gripper 35 facing the inner wall of the front section 6 is twice the distance between the lead screw 33 and the surface.
  • the apparatus 1 further comprises a proximity sensor 40 mounted on the frame 5 and a plurality of recesses 41, one for each pump 3, in the turntable 2.
  • One of the recesses, indicated by numeral 42, has a length, seen along the circumference of the turntable 2, that is at least twice, e.g. trice that of the other recesses 41 and serves as a reference for the positions of the pumps 3 on the turntable 2.
  • the turntable is rotated about its central axis until it is established by means of the proximity sensor and the motor driving the turntable that the required pump has reached the dispensing position. Subsequently, the actuator for the pump and the drive mechanism for the stirrer are activated as described above, resulting in simultaneous dispensing from one container while stirring the contents of another container.
  • Alternatives include postponing stirring to periods when no dispensing takes place (which enables more systematic stirring) or simultaneous dispensing from and stirring of the same container (especially advantageous with powders).
  • the drive mechanism, actuator and sensor require relatively few components while maintaining or even improving the reliability of the apparatus.
  • the apparatus according to the present invention can also be configured as a linear dispensing apparatus i.e. with the containers aligned is a row. And it can comprise two or more or concentric circles or rows of containers and a drive mechanism associated with each circle or row or a drive mechanism that is movable between circles and rows.
