Definitions

  • the present invention relates to a machine for capping gas cylinders, or similar containers, by crimping a capsule, generally formed of aluminum and a seal, on the nose of the cylinder valve.
  • a gas cylinder packaging installation must operate on cylinders from all sources which have significant differences between them. These differences are attributable to different causes, the main ones of which are linked to differences in shape and also in manufacturing conditions, as will be explained below. There are other secondary causes of deviations attributable to their severe conditions of use, due to the fact that they carry out a continuous rotation between the gas filling plant and the consumers through dealer distributors.
  • FIG. 1 schematically represents the upper part of a gas cylinder and also to the left part of FIG. 2, where a cylinder is indicated in perspective view, it can be seen that it has a body cylindrical of revolution terminated above by a dome 5 provided with an opening in which a flange 6 is welded; this flange 6 has two threaded parts, namely an internal thread intended to receive the threaded end piece 4, also called tail or carrot, of the tap R and an external thread 7 intended to receive the valve protection cap.
  • This comprises a valve, which can be opened and closed using a handwheel 1 and placed in a body 2 from which protrude on the one hand a tube or nose 8, carrying an external thread 9 intended for connection with the regulator of the user, and on the other hand a square 3 which precedes the threaded end piece 4.
  • the end piece has a male conical thread of the Briggs type which has the function of establishing a good tightness with Briggs female thread on the bottle flange.
  • the first three reference surfaces must be found, on all bottles in service, in relatively uniform conditions: in fact the surface: of the bottle body must not be deformed otherwise the bottle is discarded; the two other surfaces must always fulfill their respective function, that is to say allow the screwing of the protective cap and the screwing of the regulator.
  • the two faces of the square 3 of the valve they are always oriented parallel to the y-y axis, except for the die-casting tolerances.
  • the upper face of the flange which is lathe machined, also constitutes a correct reference surface.
  • the first phase i.e. the radial orientation of the cylinder valve noses always in the same direction, is advantageously carried out using a device placed in a line for packaging gas bottles. , upstream of the capping machine.
  • a preferred embodiment of such a device is the subject of the patent application filed that same day in the name of the Applicant under the title "Automatic device for radial orientation of cylindrical objects. such as gas cylinders, or the like. "
  • the machine of the invention makes it possible to fix by crimping, on the nose 8 of the gas cylinder valve, a capsule, generally formed of aluminum and of a seal, and intended to fill with a firstly a sealing function and secondly an anti-violation function.
  • the machine according to the invention operates on gas cylinders the nose of which has already been oriented in a constant direction advantageously using an apparatus which is the subject of the application for aforementioned patent, filed that same day by the Applicant.
  • This device comprises at its outlet a blocking vice (EC 2 , Figure 3) which has the function of keeping a gas bottle on standby, the nose of which is correctly oriented in an obvious direction, that is to say perpendicular to the axis of the bottle conveyor line.
  • a bottle transfer mechanism is also provided between the orientation device and the capping station. However, this transfer mechanism can be dispensed with by causing the bottles to arrive in the capping machine on the conveyor proper, which pushes the bottles against each other.
  • the gantry has only been indicated schematically at 14 in the figures. It is arranged so as to overlap the bottle conveyor designated by T.
  • the bottles have already been oriented in the aforementioned device so that their nose 8 is always directed in a determined direction; in the example considered, for an observer examining FIG. 3, the nose is oriented perpendicular to the plane of the figure in a direction directed towards the observer. After their orientation, they are immobilized in the locking vise EC 2 which keeps them waiting.
  • the machine comprises a transfer mechanism, an embodiment of which is indicated diagrammatically by TF in FIG. 3 and has been shown in detailed perspective view in FIG. 6. It comprises two branches 17, 17 ′, on each of which is fixed a horizontal arm 17a, 17'a carrying a plate 29, 30. Each plate is provided, 'in the example considered, with four shoes 31 intended to be applied against the peripheral surface of the bottle. Each branch 17, 17 'is mounted on a corresponding bar 36, 38 forming both a pivot and a slide. At their lower parts, the branches 17, 17 'are interconnected by means of an actuating cylinder 40 which is articulated on two axes 37, 39.
  • actuating cylinder 40 which is articulated on two axes 37, 39.
  • the two branches 17, 17 ′ of the transfer mechanism TF form two jaws capable of coming to clamp by means of the plates 29, 30 the bottle B held in the locking vise EC 2 .
  • the assembly formed by the branches 17, 17 ′ and the bottle is moved along the conveyor T using a jack, not shown in the figures, as far as the mediator plane of the capping station, defined schematically in Figure 6 by the YY axis and in Figure 3 by the ZOZ axis.
  • a witness 32 is provided which has the function of detecting, during the movement of the two branches 17, 17 ′, the presence of a bottle B in the locking vise EC 2 of the orientation device. If there is indeed a bottle, the presence indicator 32 initiates the transfer cycle.
  • tell-tales 33, 34 are provided on the path followed by the transfer mechanism TF so as to define a front limit switch in which the two plates 29, 30 are centered in the mediating plane of the vice of EC 2 blocking and a rear limit switch in which the two plates 29, 30 are centered in the mediator plane YY of the capping station. In this last position, the bottle, as indicated in B ', is kept clamped by the jaws during the capping operation.
  • the capping machine includes a capping device, generally designated by TC in FIG. 3 and the structure of which will be specified in the following.
  • This capping device is fixed to a support and vertical guide device of the pantograph type, designated as a whole by PA, consisting of bars in parallelogram and whose function is to allow a displacement in height of the capping device TC while retaining its axial orientation.
  • This support device PA is itself articulated on the gantry 14 so as to be able to pivot relative to the latter, it is provided with a counterweight P intended to ensure its balancing and it also carries on the one hand means adapting the height of the line of action of the capping device to the height of the nose 8 of the bottle tap and on the other hand means of transverse adaptation of the position of the capping head to the spatial position of the valve nose, in order to compensate for an excessive eccentricity of the collar relative to the dome of the bottle, possible twisting of the valve and faults of the bottle base.
  • the transfer distance between the blocking vise EC 2 and the mediator plane TC of the capping device has been intentionally increased in order to better show the different phases.
  • position B 1 of the gas bottle which corresponds to the locking vise EC 2
  • the transfer mechanism TF begins to move to the left, looking at FIG. 2, and it brings the bottle B into contact with the flange 10 at the point designated by a.
  • the transfer mechanism continuing its movement, the bottle raises the flange 10, and consequently all of the support PA and of the capping device TC in correspondence with the curve drawn in ab on the bottle dome.
  • the support function of the support PA is provided by the plate 11 which bears by its lower face against the aforementioned reference surface formed by the upper face of the collar 6 of bcuteille.
  • This process corresponds to an approach guide but it is however necessary to place the plate 11 in the appropriate zone and allow it to engage between the flange and the tap nose.
  • the leading edge is given. of the collar, considering the line XX of advancement of the bottles, a tapered profile, highlighted in FIG. 2 and the thickness of the wafer is kept below 4 mm.
  • the plate 11 is now applied by its upper face against the lower generatrix of the surface 9 of the tap nose, it must be immobilized to maintain the capping device TC at the height thus adjusted.
  • This blocking is ensured by means of a brake shown diagrammatically at 15 and acting on one of the bars of the PA support.
  • the position of the capping device on the pantograph is obviously adjusted in height in correspondence with the height position of the plate 11 of the flange 10 so that the application of this plate against the tap nose necessarily places the axis of the capping device at the level of the axis of the tap nose, defined by the line AA in FIG. 2.
  • the height 0 h the capping device of which is raised in the last phase, has also been highlighted in this figure. height adjustment, corresponding to position B 3 of the bottle.
  • this lifting system with plate and jack could be replaced by a system with slides inclined upwards and acting so as to bring the capping device gradually to the level of the tap nose.
  • these means consist of a chassis 43 essentially in the form of a frame, which is articulated on the four bars PAl, PA2, PA3, P A 4 of the support device P A, of the pantograph type, in the following manner.
  • Two trees 46, 47 are provided, oriented horizontally and constituting the axes of articulation of the respective bars PA1, PA3 and PA2, PA4 of the parallelogram, the connection between said shafts 46, 47 and the bars of the parallelogram being ensured by means of ball bearings indicated diagrammatically at 54.
  • sliding bearings 48, 49, 50, 51 are fixed externally, in particular ball bearings, by means of which the chassis 43 can slide on the shafts 46, 47, the interval of cculatorium being designated by j in Figure 3A.
  • This interval is chosen at the design so as to take into account the maximum deviations that can be created by bottle defects, these deviations can reach + 15 mm, that is to say that the interval j is given a value 30 mm.
  • the capping head TC is fixed lower on a plate 52 placed at the bottom of the chassis 43. In addition, this plate 52 carries above the control apparatus, indicated schematically at 28, of the capping head.
  • this transverse adaptation system of the capping head is not limiting of the invention and that any other system can be adopted which makes it possible to obtain said transverse deflection interval of the capping head.
  • the entire capping head can be mounted like a pendulum by suspending it from a horizontal pivot axis, placed in the vertical mediating plane of the bottle conveyor line and located above the capping at a sufficient height for the movement of the latter to be substantially horizontal. It is also possible to suspend the entire capping head from a vertical upper pivot centered in the mediating plane of the conveyor line.
  • the capping device Before carrying out the actual capping operation, the capping device must be centered in the mediating plane of the capping station, defined by the vertical axis ZZ in FIG. 3 and the axis YY in the figures. 4 and 6.
  • This capping device is shown in detailed plan view in FIG. 4. It comprises a crimping head comprising a punch 20 provided with a front recess 21 which engages, under the action of the drive device shown diagrammatically at 22, on the capsule C placed on the nose 8 of the tap.
  • a clamp designated as a whole by PS in Figure 4 and whose line of action is centered on the axis of the crimping head TS.
  • This PS clamp comprises two branches 23, 23 a which can pivot around axes designated respectively by 44 and 44a.
  • the branches end with jaws 24, 24a and they are actuated by a double-acting jack 25 which is articulated on the branches by means of axes designated by 26 and 26a.
  • a cylinder 27 is provided, the axis of which is placed in the extension of the axis of the cylinder 22 of the crimping head, and which serves to bring the PS clamp closer or further away from the path followed by the bottle taps .
  • This mode of actuation has no limiting effect on the invention, the only condition being that the clamp fulfills its function.
  • the jack 22 of the TS crimping head is installed in a fixed position on the frame 43 so as to make the punch 20 go out or come in while the structure, constituted by the clamp PS, its clamping jack 25 and its transfer jack 27, is mounted on slides integral with the chassis 43, and not shown, in order to be able to execute an alternating movement of translation in the direction YY.
  • the jack 25 is then actuated so as to bring the two jaws 24, 24 ⁇ to corresponding parallel faces of the square 3, as shown diagrammatically at 24 ', 24'a in FIG. 4. It should be noted that thus the chassis transverse movement 43 has been moved according to the spatial position of the valve, to bring the capping head TC in the correct position relative to the existing bottle.
  • the jack 22 of the crimping head TS is actuated so as to release the punch 20 which comes to crimp the capsule on the external thread 9 of the nose of the tap.
  • this capsule C is on the corresponding nose and the capping machine has a system for automatically performing this positioning.
  • This system comprises a capsule supply chute, which has been designated by 16 in FIGS. 3 and 4 and which is connected at its upper end to a capsule reservoir, provided with a vibrator of known type used to engage the capsules. always in the same orientation in the chute 16.
  • This chute is connected at its lower end to a distributor, designated by 18 and shown in more detail in FIG. 5.
  • the distributor 18 comprises at its mouth a small valve designated by 45 and allowing the capsules C to pass one by one, which are provided with a tearing tab L, in order to keep them in the trajectory, materialized by the line SS parallel to the axis XX of the conveyor line.
  • the first capsule is immobilized by said valve 45, with its opening directed towards the nose 8, so that the latter, during the transfer movement of the gas bottle, penetrates by its front edge into said opening of the capsule which rocks, supported by its rear surface on the axis of the valve, while being retained by the latter, so that it finally engages as indicated in C ', on the tap nose by which it is held in place until in the crimping station.
  • the longitudinal axis of the dispenser is oriented relative to the mediating plane YY of the capping station at a well determined angle, designated by a in FIGS. 4 and 5 and forming the subject of an initial setting.
  • this distributor is fixed to the support and vertical guide device PA so that it follows its movements.
  • the chute 16 must have a certain flexibility to absorb the relative movement between the dispenser and the capsule reservoir. This problem is solved by using an appropriate plastic material and by giving an appropriate curvature to its longitudinal axis.
  • the TC capping device is thus placed level with the y-y axis of the valve nose.
  • the transfer mechanism TF continues its movement towards the mediator plane Z-O-Y of the capping station, where it is stopped under the action of the presence indicator 34, then releasing the bottle.
  • the frame 43 with slides 48, 49, 50, 51 brought the capping head in correspondence with the spatial position of the bottle valve.
  • the centering of the capping device on the axis yy of the tap nose is then carried out by means of the PS clamp, the jaws 24, 24 a of which are applied against the corresponding faces of the square 3 of the tap, which establishes a coincidence between the axis of the crimping punch 20, 21 and the axis yy of the tap nose. It should be noted that this entrained, during its transfer, a capsule C made available at the end of the distributor 18.
  • the capping device is now ready to carry out the crimping operation, which is triggered by another indicator 19 for checking the correct orientation of the tap nose.
  • the punch engages by its recess 21 on the capsule C and it actuates an inner crimping ring, formed of an elastic material which comes to clamp the capsule and compress its peripheral surface to engage it between the threads of the thread of the nose 8.
  • valve of the bottle is held by the pliers PS which thus plays the role of anvil for the crimping head and that on the other hand the body of the bottle is retained by peripheral stops, shown diagrammatically at 41, 41a, these stops being actuated by jacks 42, 42a.
  • a pressure switch intervening in the apparatus indicated diagrammatically at 28 and reacting to the final crimping pressure causes the cylinders to be withdrawn from the capping head TC so that the bottle, finished crimping, can be freely driven by the conveyor T, by actuating in passing an element of control, indicated schematically at 35, which ensures the return to the initial state of the machine components.
