Definitions

  • the present invention refers to an apparatus for metering liquid products.
  • Apparatuses are known for metering liquid products in which the interception and control of the outgoing flows are carried out by means of electric and/or pneumatic valves.
  • the above mentioned drawbacks occur even more frequently in industrial sectors like the one for the production of perfumees, in which corrosive products are manipulated, such as natural or synthetic essences of perfumees and the like, acids, bases, organic solvents and aromatic products.
  • the apparatuses for treating these substances require the use of special materials which are highly resistant and, accordingly, of much higher cost.
  • the main object of the present invention is to provide an apparatus which overcomes the above drawbacks.
  • an apparatus for metering liquid products comprises a plurality of stator elements (1) of peristaltic pumps, said elements being aligned to form one or more rows (two opposite rows at the same level in the examples of Figs. 2A-2B).
  • Each of said elements (1) makes up a rigid support for a corresponding pipe (2) of flexible and elastic material (made of TEFLON, for example) with a section (20) which communicates with a vessel or bottle (3) holding a liquid product, and an opposite section (21) for the discharge of the product.
  • the elements (1) of each row are spaced closely to each other to form a compact battery in which each element results therefore associated to a corresponding liquid product.
  • An apparatus according to the invention comprises, in addition, at least one rotor (4) for peristaltic pumps (in number of two in the drawings of Figs. 2A-5B).
  • Each rotor (4) is made up, in the example of the figures of the attached drawings, of two circular plates (5) connected between them by a plurality of idle transverse rollers (50) whose shafts extend orthogonally to plates (5) in correspondence of their circumferences: the two plates (5) being also connected to each other by a central shaft (51) parallel to rollers (50) and supported by the arms of a fork (6).
  • rollers (50) are in number of four and angularly equidistant from each other.
  • the shaft (50) of said rotor is connected to an electric motor (7) via a coupling (75).
  • Said motor (7) is fixed to one of the arms of fork (6); advantageously, it is of step-by-step type able to be used in association with a programmable control unit to be described later on in greater detail.
  • the fork (6) is associated to a pneumatic actuator (8) to allow the movement thereof in both directions orthogonally to the shaft of rotor (4), that is, to allow the latter to be moved from the positions shown in Figs. 1A and 1B to those shown in Figs. 1C and 1D, and vice versa.
  • Each rotor (4), along with the driving motor (7) and corresponding actuator (8), is carried by a carriage (9) so as to be moved along a row of stators (1) with which it is associated (arrow "F" of Fig. 2A and Fig. 4C), that is, to allow the positioning thereof in correspondence of the stators (1) each time selected.
  • the movement of the carriage (9) is operated by a programmable electronic unit (UE) to which an electric motor (90) is linked to proporley drive said carriage into motion.
  • UE programmable electronic unit
  • the latter consists of a platform (91) resting upon straight guides (92) which extend parallel to the rows of stators (1), and of a belt (93) which supports the rotor units (4) at a height corresponding to that of the stators (1).
  • the carriage (9) is suitably positioned within a stationary structure (S) which exhibits, relative to the example shown in Figs. 4A-5B, two shelves (MS) upon which the bottles (3) are made to rest.
  • the latter are connected to the section (20) of the respective hoses (2) via corresponding pipes (30) and are located on the back of stators (1).
  • Said control unit (UE) is programmed to locate each rotor (4) in correspondence of the stators (1), according to a program which takes into account the sequence of the dosages to be carried out as predetermined by the operator.
  • UE control unit
  • Both the unit (UE) and the programming system are per se known to those skilled in the art and, accordingly, will not be described herein in greater detail.
  • Each actuator (8) and each motor (7) is linked to the programmable unit (UE) which provides for the operation thereof according to the preset program.
  • the unit (UE) in question is also provided with a memory which records the positions of all the stators (1).
  • a belt (93) ring-closed over two driving pulleys (94). Said belt (93) extends orthogonally to the direction (F) of movement of the carriage (9). Connected to one of said pulleys (94) is an electric motor (95). Resting upon the belt (93) is an electronic scale (96) on the pan of which is a container (97) able to receive the doses of the products taken out each time from the bottles (3). The activation of the motor causes the winding of the belt (93) over the pulleys (94) and, accordingly, the displacement of the scale (96) with container (97) up to a row of the stators (1) each time selected by the program (arrow "G" of Fig.
  • the scale (96) may act for simply checking that the amount of liquid taken out each time from the bottles (3) is equal to the desired value, or for driving the motors (7) of the rotor units by means of the programmable unit (UE), as shown schematically in Fig. 3, to which it can be connected in a conventional manner.
  • UE programmable unit
  • the carriage (9), operated by the respective motor (90) according to the program, provides for disposing the units (4) in correspondence of the stator (1) connected to the bottle (3) from which the liquid is withdrawn as shown by the arrow (F).
  • the scale (93), with the container (97) resting thereon, is as well subjected to the same movement.
  • the actuator (8) of the rotor unit which is in front of said stator (1) (one stator of the left row in Fig. 2B or one stator of the right row in the example of Fig. 2C and Fig. 5A). This causes the rotor (4) to be positioned as shown either in Fig. 1C and Fig. 2B, or in Fig. 5A.
  • the motor (95) is operated to move the scale (96) until the container (97) thereupon results in alignment with the discharge section (21) of the hose (2) of the selected stator (1).
  • the actuation of the motor (7) of the selected rotor unit causes a corresponding rotation (clockwise for the rotors of the right row and, vice versa, anticlockwise for the rotors of the left row) of the relevant plates (5) and rollers (50).
  • the pressure exerted by the rollers (50) onto the hose (2) causes a sort of continuous "squeezing" of the latter and, therefore, the pumping and discharge of the liquid out of the respective bottle (3) and the collection of same liquid within the container (97) below.
  • the control unit (UE) After a preset number of revolutions or "steps" of the motor (7), the control unit (UE) operates the stop thereof. Upon completion of this stage, it is also possible to take the liquid remained within the hose (2) back into the bottle (3) by a reverse rotation (anticlockwise for the rotors of the right row and, vice versa, clockwise for the rotors of the left row) of the plates (5). Finally, after repositioning the rotor back in the start position, the carriage (9) is moved to a standby station in which the operator takes out the container (3) either to replace it with an empty and clean one, or to dispose it in correspondence of other stators (1), of the same row or the opposite row, to put doses of other products therein to thus form a mixture.
  • the motors (7), actuators (8), motor (90) and motor (95) are driven by the unit (UE) according to the selected program.
  • the metering may be controlled by connecting the scale (96) to the unit (UE), or simply verified by eliminating or omitting said connection.
  • the present apparatus may be used in all the industrial sectors in which there is required an accurate metering of liquid substances, regardless of the nature and final use thereof.
