Definitions

  • the present invention relates to closing bottles and the like by screw plugs.
  • Automatic machines which carry out subsequent steps for packaging various articles, e.g. pharmaceuticals, marketed in bottles or the like.
  • processing means are aimed at checking the products characteristics that can be modified and commanding suitable operations if these characteristics vary from the programmed ones.
  • the system is not precise enough and little reliable, and allows only for sampling based check.
  • the publication US-A-2760391 describes a bottle capping device in which a bottle is kept stationary while capping means are lowered to screw a cap onto the neck of the bottle.
  • the device includes an upper drive shaft, an upper jaw mounted to the shaft for longitudinal movement thereon, means for biasing the jaw towards the lower end of the shaft, a driven shaft, a lower jaw mounted on the driven shaft, means for suspending the driven shaft from the drive shaft, thus permitting longitudinal movement between the shafts to engage and disengage the jaws.
  • Means for engaging the caps are mounted on the driven shaft while means for adjusting the position of the driven shaft are mounted on the suspension means. With this configuration it is possible to vary the amount of torque necessary to urge the upper jaw against the biasing means, thus disengaging the upper jaw from the lower jaw.
  • the capping device does not screw the cap onto a bottle with an excess of torque, and the amount of torque can be adjusted from outside of the structure.
  • the object of the present invention is to propose a device that allows bottles and the like to be closed by screw plugs in the best way, and to effectively check the tight sealing of these bottles.
  • Another object of the invention is to propose a closing device that allows to adjust, in a simple way, the tightening torque of the above mentioned screw plugs, as well as to measure continuously this tightening torque, so as to permit to give a guarantee certificate about the products quality.
  • the reference numeral 1 indicates the device closing bottles and the like by relative screw plugs 2.
  • the device 1 features a sleeve 3 that is rotatably carried, about a vertical axis, by a pair of horizontal and superimposed plates 4 and 5, by means of rolling bearings 6 and 7.
  • the plates 4, 5 are elements of a carousel, made to rotate about a vertical axis, in a known way.
  • the outer part of the sleeve 3 forms a toothed wheel 8 connected with a toothed ring 9 which is integral with the fixed support structure of the above mentioned carousel.
  • the tubular shaft 10 is connected for rotation with the sleeve 3, through a suitable tang 11 which engages a longitudinal groove 12 made on the internal surface of the sleeve 3.
  • tubular shaft 10 In its lower part, the tubular shaft 10 features a threaded section 10a for screwing another sleeve 13, coaxial with the shaft 10.
  • a cylindrical chamber 14 is formed inside the tubular shaft 10, in its lower part, substantially in correspondence with the connection with the sleeve 3.
  • the chamber 14 houses an escapement means 100 that transmits the screwing motion for the plug 2.
  • the escapement coupling means 100 includes two coaxial cylindrical members 15, 16, upper and lower respectively, having the same outer diameter.
  • the members 15, 16 are coupled to each other, during the screwing motion transmission, at respective facing planes, equally inclined with respect to the longitudinal axis of the device.
  • the two members 15, 16 match with each other and due to their mutual positioning, they cooperate to define a continuous cylindrical element.
  • the upper member 15 of the escapement coupling means carries a pair of rollers 17, idling about a radial axis and situated in diametrically opposed positions.
  • the rollers 17 engage respective longitudinal slots 18 made on the tubular shaft 10. Therefore, the member 15 is connected for rotation with the tubular shaft 10 and is driven in rotation thereby.
  • the lower member 16 of the escapement means is rotatably carried by an axial bearing 19 situated inside the sleeve 13. In its lower part, the member 16 extends into a rod 20 that passes axially through the sleeve 13, and below the said sleeve 13, it is made integral with the case 21 of known gripping means 22.
  • a tube 25, set longitudinally inside the tubular shaft 10, is aimed at urging, via an axial bearing 24, the upper member 15 of the escapement means.
  • the top of the tube 25 can be connected to known means for delivery of compressed air, which are not shown in the drawings.
  • the compressed air is supplied to the gripping means 22 through a pipe 26 that extends from the lower part of the tube 25 and passes freely through the cylindrical members 15, 16 of the escapement means.
  • the tube 25 is pushed in axial direction by the pressure present inside a cylindrical chamber 27 defined by a jacket 30, that forms a kind of bell, and delimited by suitable tight seals 28, 29.
  • the tube 25 passes axially through the jacket 30 that, in its lower part, partially covers the tubular shaft 10.
  • the chamber 27 is supplied with compressed air by a pipe 31.
  • the thrust exerts its action on the tube 25 by means of a ring 32 that strikes against a suitable shoulder formed outside the same tube.
  • the jacket 30 carries rolling means, indicated with sketched line 33, on a radial axis.
  • the rolling means 33 engage a ring-like cam 34, concentric with the carousel axis and integral with the fixed structure thereof.
  • the cam 34 controls the axial approach of the device to the bottle to be closed.
  • a radial arm 36 guided by a vertical shaft 37 extending from the jacket 30, is bound, by means of a transversal pin 35, to the tube 25, over the jacket 30.
  • the arm 36 carries a vertical bar 38 designed to operate suitable sensor means for checking closure of the bottles.
  • the device is equipped with a first sensor means 39 and a second sensor means 40, constituted by e.g. conventional proximity sensors, situated on the same horizontal plane and suitably spaced apart along to the direction A of the carousel rotation.
  • a first sensor means 39 and a second sensor means 40 constituted by e.g. conventional proximity sensors, situated on the same horizontal plane and suitably spaced apart along to the direction A of the carousel rotation.
  • the sensors means 39, 40 are supported by the fixed support structure of the carousel.
  • the sensors means 39, 40 are designed to detect passage of a flag-shaped tab 41 secured to the top of the bar 38, by a radial transverse bar 42.
  • the tab 41 is formed by e.g. a plate that extends for a suitable length in the carousel circumferential direction.
  • the bottle is carried by the carousel, while it rotates, below the closing device.
  • the carousel carries a plurality of closing devices, spaced apart along its periphery, with respective bottles to be closed aligned therebelow.
  • the plug 2 is held by the jaws 23 of the gripping means 22 that is driven into rotation by the tubular shaft 10 through the transmission escapement coupling means 100.
  • the shaft 10 is rotated by the sleeve 3 that is in gear engagement with the ring 9 by means of the toothed wheel 8.
  • the upper member 15 of the escapement means 10 that is connected for rotation to the tubular shaft 10 by means of the rollers 17 running in the slots 18, drives the lower member 16, integral with the gripping means 22.
  • the upper member 15 is pushed axially due to the force applied by the tube 25, whereas the tube 25 is pressed by the pressure of the compressed air inside the cylindrical chamber 27.
  • the upper member 15 transmits tightening torque to the lower member 16 by means of the inclined opposed surfaces, in correspondence with which the members 15, 16 are coupled.
  • the thrust force that pushes the upper body 15 causes a transverse component force in correspondence with the above mentioned inclined surfaces, and this transverse component force gives rise to the screwing torque.
  • the plug 2 carried by the gripping means 21 is screwed onto the bottle 200.
  • the lower member 16 of the escapement coupling means 100 stops, while the upper member 15 continues to rotate, still driven by the tubular shaft 10.
  • the upper inclined surface of the lower cylindrical member 16 acts as a fixed cam on the correspondent lower inclined surface of the upper cylindrical member 15 that, while rotating, slides thereonto.
  • the upper member 15 reciprocates upwards and downwards every turn thereof.
  • This reciprocating movement of the member 15 of the escapement means is transmitted to the tube 25, that is supported on the same member 15 by the bearing 24; in its turn, the tube 25 drives the vertical bar 38 aimed at operating proximity sensors 39 and 40.
  • the first sensor 39 detects the passage of the tab 41, carried by the bar 38 of the device, as indicated with the sketched line 41a in figure 6.
  • the sensor 39 supplies a reference signal, automatically compared with the signal supplied by the second sensor 40, situated downstream of the previous one, in the carousel rotation direction.
  • the sensors 39, 40 detect constant signals.
  • the lower member 16 of the escapement means 100 stops and causes vertical reciprocating movement of the bar 38.
  • the sensors 39, 40 detect an alternate signal which indicates that the pre-determined tightening torque for the plug has been reached, i.e. the bottle 200 has been tightly closed.
  • the sensors 39, 40 allow for detaching possible failure during the plug screwing.
  • the constant signal determined by the immediate alternate movement of the bar 38, it means that the plug has not been screwed regularly, e.g. because the plug has jammed.
  • the described device allows to check the bottles real tight seal closing operation in which screw plugs are applied thereto, immediately rejecting possible defective bottles.
  • the device also allows to suitably adjust the value of the plug tightening torque.
  • it is made possible to change the value of the pressure inside the chamber 27, that determines the value of the axial thrust acting elastically on the escapement coupling means 100 transmitting the tightening torque for the plug.
  • the subject device allows to close the bottles with screw plugs in best way, permitting in particular to check the actual tight seal closure of the bottles.
  • the closing device allows the plugs tightening torque to be adjusted in a simple way and to be measured continuously.
  • the closing device is simple in its construction and versatile to be adapted in accordance with the features of the bottles to be closed.
