Definitions

  • the present invention relates to packaging lines of fluid or fluidizable cosmetic products such as waxes, pastes and the like and more in particular to a batcher apparatus.
  • the cosmetic industry employs dosing apparatuses as batchers of waxes and pastes or more in general of a cosmetic product that is either fluid at room temperature or fluidizable by heating it to a certain temperature, to fill tubes, vases or other suitable packaging containers for its sale in retail shops.
  • these apparatuses consist of a body defining therein an inlet duct, usually provided with thermostatically controlled heaters to maintain the fluid or fluidized product at a certain constant temperature, connected directly to a reservoir of the product.
  • a gear pump thrusts the product from the inlet duct to an outlet duct that is closed by an outlet or delivery valve.
  • the dose is fixed by precisely timing the opening of the delivery valve, often in coordination with an intermittent activation of the gear pump.
  • the dose of product for filling the packaging container for retail sale must be precisely established and remain constant in time in order to ensure the outletting of exactly the fixed quantity of product into each container by respecting a rather strict tolerance range.
  • Factors of perturbation are indeed numerous. Among these, the accuracy of control of the temperature of the product in the duct is of primary importance because variations of the temperature may change the rheologic characteristics of the product and cause variations of the volume of product released at every opening cycle of the delivery valve.
  • Another perturbing cause of the outlet dose is due to changes of the level of the product in the reservoir that is commonly placed at a higher level of the packaging batcher apparatuses and from which the product is gravity fed as the level of the product progressively lowers in the reservoir.
  • the batcher of the present invention differs from the known batchers by having defined therein an accumulation or buffer chamber of the product flowing into the batcher.
  • the level of the product in the accumulation chamber thus defined within the body of the batcher is monitored by a level sensor to which the actuator of an intercepting valve purposely included in the inlet duct of the fluid product is slaved, in order to maintain a level substantially constant of the fluid product in said chamber of accumulation (buffer) chamber.
  • a thermostatically controlled heater to maintain the product contained in the buffer chamber at a constant preset temperature.
  • the buffer chamber there is a mechanical mixer that maintains homogeneous the composition of the fluid product by preventing stratifications and/or temperature disuniformities throughout the volume of product contained therein.
  • the operating conditions of the gear pump that thrusts the fluid product toward the delivery nozzle as well as of the outlet valve and more precisely the level of the product contained in the buffer chamber, the temperature and the rheological characteristics of the fluid product, are thus maintained outstandingly constant and uniform in time, irrespectively of the lowering of the level of the product in the supply reservoir as well as of prolonged interruptions of the delivery cycles.
  • Figures 1 and 2 are respectively an elevation view partially in section, and a plan view of a batcher made according to the present invention; Figures 3 and 4 illustrate a different embodiment of a batcher of this invention.
  • FIG. 1 A first embodiment of the batcher of this invention is shown in Figures 1 and 2.
  • the apparatus comprises a body 1 of a material resistant to the products to be handled, generally of a metal or a metal alloy and most commonly of stainless steel or anodized aluminum, within which a feed or inlet duct 2 is defined, the inlet hole of which is connectable to a reservoir of the product, commonly through a rigid or a flexible tube (not shown in the figures).
  • the reservoir is generally placed at certain height overhead of the array of batchers of the packaging lines, such that the fluid or the heat fluidized product may flow by gravity toward one or most commonly toward a plurality of batchers.
  • the valve for outletting a certain quantity of product at every cycle is a needle valve driven by a solenoid 6a, the opening time of which is set by timers that may be adjusted from a control console for outletting a preestablished amount of product during every opening phase.
  • control phase of the opening time of the valve generally controls also the operation of the pump 4.
  • a small anticipation and/or delay (outphasing) of the instant of opening and closing of the flow aperture of the fluid through the outlet valve in respect to the start and stopping of the pump may be deliberately introduced.
  • a buffer chamber 8 is formed within the body 1.
  • the dimensions of the chamber 8 are sufficient to contain a certain volume of fluid product.
  • a paddle mixer 9 driven by a respective motor Ma, preferably of adjustable speed, and a thermostatically controlled heater.
  • the level of the fluid product in the buffer chamber 8 is constantly monitored by a level sensor 10 and maintained constant at a preestablished level by controlling the actuators of an intercepting valve 11 installed in the feed conduct 2, upstream of the buffer chamber 8.
  • the valve 11 is preferably a rotating valve driven by a pneumatic cylinder 1 la, controlled by the level sensor 10 through a control system.
  • an outlet valve of a rotating type similar to the intercepting valve 1 1 , also driven by a cylinder.
  • An advantageous characteristic of rotating valves is of allowing a single implementation of a recirculation of the fluid product through a by-pass duct back into the buffer chamber 8 during the closing phases of the outlet valve. Therefore, in this case the pump may function in a continuous mode thus preventing intervals during which the fluid product remains still in the outlet duct.
  • outlet valve 6r is of a rotating type driven by a cylinder 6b.
  • gear pump 4 that pushes the fluid product through the outlet duct instead of being driven by an electric motor as in the example shown, may be driven by a compressed air motor.
  • timing devices may be of various types. For example electronic timers that may be preset through a keyboard or a control console, may be used. Alternatively, a magnetic or optical encoder mounted on the axle of the motor that drives the pump may be used, such that after a certain preset numbers of revolutions of the pump axle, the outlet valve 6a (6r) is closed and eventually the pump 4 itself is stopped.
  • a single pump 4 and a single outlet valve 6s (6r), have been shown, included in a single delivery path 5-7 (provided also with a recirculation duct 5r in case of a rotating outlet valve).
  • a single buffer chamber 8 for maintaining the fluid product at a substantially constant level and to a constant temperature, while continuously mixing it.
  • each delivery paths will include its own pump 4 and its own outlet valve 6s (6r) for delivering precise amounts of product through a plurality of nozzles 7, thus multiplying the production capability of each single batcher of the packaging lines.

Abstract

L'invention porte sur un doseur destiné à des produits cosmétiques, fluides ou à fluidisation thermique, et doté d'une chambre tampon (8) logée dans la gaine d'alimentation (2). Le niveau du produit dans la chambre tampon est contrôlé par un détecteur de niveau (10) permettant de contrôler le dispositif de commande d'une vanne intentionnellement introduite dans la gaine d'alimentation (2) en amont de la chambre tampon (8) afin de conserver un niveau sensiblement constant de produit dans ladite chambre tampon (8). Cette chambre tampon (8) comprend un agitateur mécanique (9) qui préserve l'homogénéité de la composition du fluide en empêchant les stratifications et/ou les inégalités de température dans la masse de produit contenu à l'intérieur. Ces conditions de fonctionnement de la pompe à engrenages (4) en aval de la chambre tampon (8) et du conduit d'écoulement (6s) sont maintenues constantes indépendamment des changements de niveau du produit dans un réservoir d'alimentation suspendu et indépendamment des interruptions prolongées de la séquence des cycles d'administration.
