Definitions

  • the present invention relates to the technical sector of automatic machinery for filling containers with liquid products.
  • a variety of automatic machines which fill containers such as bottles or vials with liquids. These machines usually have carousels or starwheels which rotate about a vertical axis and which are designed to receive the bottles to be filled in orderly fashion from a feed line.
  • the carousel mounts means for dispensing the liquid product which work in synchrony with means for lining up the bottles with the corresponding nozzles of the dispensing units themselves. The filled bottles are then transferred to an outfeed line.
  • the aforesaid dispensing units usually have a plurality of elements which exert a preset pressure on the liquid, and which are connected to liquid feed tubes.
  • the feed tubes are connected to the liquid tank through valves mounted on the outermost edge of the carousel.
  • a container filling apparatus as in the preamble of claim 1, having a plurality of revolving charging cylinders and respective pistons by which a fluid material supplied into the cylinders with their pistons at the limit end of their intake strokes is subsequently pushed out of the cylinders to fill respective containers.
  • An adjusting screw is provided to set by one of its end the limit of the intake stroke of the piston rod of each piston and has a sprocket-like wheel fixed to its other end and actuated in incremental rotation by the piston rods of stationary air cylinders fixed to the apparatus frame when the wheel, revolving with its cylinders, is engaged by the piston rods.
  • the activation of the air cylinders is controlled by electrical control means by which the limit of the intake stroke of any piston and, therefore, the filling quantity of the corresponding cylinder can be adjusted without danger and without stopping the operation of the apparatus.
  • the object of the present invention is to provide a device which is capable of dispensing a liquid product to rotating elements and which is especially suitable for application on automatic bottle fillers.
  • Another object of the invention is to provide a device that uses a simple, reliable technique and that is suitable for a wide range of bottle sizes.
  • the space occupied by the claimed device is thus very limited, making for a very practical set-up, and allowing easy access to the internal parts of the carousel. Furthermore, since the structure of the device is very simple, the machine to which it is applied has added efficiency and reliability.
  • the machine for filling bottles 1 with a liquid product has means 2 for feeding the said bottles to a carousel 3 which rotates about a vertical axis in the direction indicated by arrow A.
  • Feed means 2 consist of a bottle 1 conveying line 4 along which there is an auger 5 which rotates axially in such a manner as to space the conveyed bottles 1 apart.
  • Auger 5 is designed to operate in conjunction with a distributor 6, shaped like a star, for example, which rotates in the direction of arrow B.
  • the bottles to be fed are held and guided by recesses 6a in distributor 6 and by ring guide 7 which partially surrounds the distributor itself.
  • Carousel 3 receives bottles 1 fed by distributor 6 one by one at the point where the equally spaced grippers 8, mounted on the circumference of the carousel itself, are activated. Carousel 3 also mounts dispensing units, labelled 9 in the drawings, which fill the liquid product into bottles 1.
  • a full bottle outfeed system 10 consisting of a conveyor line 11 and another distributor 12, shaped like a star, for example, which rotates in the direction of arrow C.
  • the outgoing bottles are received by distributor 12 at the point where they are released by grippers 8 and are held and guided by recesses 12a in the distributor and by a ring guide 13 which partially surrounds the distributor.
  • dispensing units 9 consist of a plurality of cylinder and plunger assemblies mounted by carousel 3 which lines them up with grippers 8.
  • Each of the said cylinder and plunger assemblies 14 is connected through a valve 15 to a liquid feed chamber 16 and to a filling nozzle 17 alternately.
  • Chamber 16 is mounted on a platform 18 attached to the rotating part of carousel 3.
  • Platform 18 is secured to the top of a vertical shaft 19, rotated continuously by the drive motor of the machine.
  • Chamber 16 concentric with the axis of carousel 3, is fed through a tube 20 connected to a tank, which is not illustrated, outside the machine.
  • Tube 20 is located above chamber 16, diametrically with respect to carousel 3, and is supported by a frame 21 attached to the fixed structure of the machine.
  • Tube 20 is connected to a mouthpiece 22 leading out of chamber 16 in accordance with the axis of rotation of the carousel.
  • valve 15 consists of a lower casing 23 fixed to carousel platform 18 and an upper casing 24 which rotates on a pin 25 about the vertical axis of valve 15 itself and in relation to fixed lower casing 23.
  • Upper casing 24 has a cap 26 held by pin 25 and pushed axially by a spring 27 which presses down on casing 24.
  • Lower casing 23 is crossed by a pair of parallel, vertical holes 28 and 29, which, at their bottom ends, are connected with a pair of ducts, respectively 30 and 31, made in platform 18.
  • Duct 30 leads out of chamber 16, whilst duct 31 is connected to dispensing nozzle 17.
  • Platform 18 is also crossed by a vertical hole 32, whose bottom end is connected to cylinder and plunger assembly 14 and whose top end extends into lower casing 23 of the valve.
  • the axes of holes 28, 29 and 32 are distributed around a circle concentric with the axis of rotation of upper valve casing 24.
  • Upper, rotating casing 24 is crossed by an approximately semicircular channel 33 in a horizontal plane.
  • channel 33 At each end and in the middle of channel 33 there are downward opening holes 33a, 33b and 33c which serve to connect hole 32 to ducts 30 and 31 alternately, in accordance with the angular position assumed by rotating valve casing 24.
  • Cap 26 of rotating casing 24 has on its top an eccentric pin 34 which rotates axially and held by a sprung bolt 35.
  • Pin 34 is designed to intercept a pair of cams 36 and 37, respectively first and second cam, during the rotation of carousel 3, the said cams being carried by fixed frame 21 of the machine in diametrically opposite positions in relation to the axis of the carousel itself.
  • Cams 36 and 37 have a chamfered face designed to act as a sliding guide for pin 34.
  • Cams 36 and 37 are supported by actuators 38 and 39 respectively driven in a vertical direction in such a manner that they can be lifted to positions 36a and 37a in which they are disengaged from pins 34. The raising of cams 36 and 37 make it possible for washing cycles to be performed on the machine.
  • valve 15 switches the connection of cylinder and plunger assembly 14 from liquid suction duct 30 to duct 31 which conveys the liquid to nozzle 17.
  • eccentric pin 34 of the valve is intercepted by cam 36, thus causing upper casing 24 of the valve to rotate in relation to lower, fixed casing 23.
  • channel 33 of casing 24 is connected through holes 33a and 33b to hole 32 and to duct 31, thus enabling the liquid to flow out through the nozzle.
  • cam 37 intercepts eccentric pin 34, causing casing 24 of valve 15 to rotate to the initial position, that is to say, with channel 33 connected to duct 30 and cylinder and plunger assembly 14. At the same time, the next suction stage begins and liquid flows into cylinder and plunger assembly 14.
  • the device described constitutes a reliable, efficient means to supply a liquid product to the dispensing units 9 rotated by the carousel.
