Description

The present invention relates to an automatic machine for placing plugs on bottles, in particular glass plugs packaged in packaging plates, this machine comprising at least one device for feeding plugs, a device for placing a plug cap on a bottle and a device for feeding and evacuating bottles.

With the increased risk of cork taste encountered by the use of traditional cork stoppers for wine, it seeks to replace the cork stopper with plugs made of various materials and varied. One of the solutions is to use caps made of glass, which is a totally chemically neutral material and therefore has no influence on the quality of the wine. These plugs generally comprise a slightly frustoconical foot adapted to be housed in the neck of the bottle, surmounted by a cylindrical head of a diameter greater than that of the foot adapted to bear on the neck of the bottle. The seal is provided by a seal in the form of an annular ring having an L-shaped section housed in a groove provided between the head and the foot and covering at least the top of the foot and the underside of the head, namely the parts of the stopper in contact with the end zone of the neck of the bottle. These caps are generally packaged upside down, upside down and foot up, in individual housings provided in flexible thermoformed plates to prevent contact between them and any risk of breakage. They are notably aligned in rows and columns.

The major difficulty inherent in this type of stoppers lies in its fragility and its breaking power that make handling and placing it on the bottle delicate especially by an automatic process. To date, the implementation of this type of caps uses traditional machines, in which the caps are removed from their packaging by a vacuum gripper to power the machine by means of a vibrator, the glass bottles are also brought by a motorized conveyor belt and the cap is introduced in force in the neck of the bottle by a jack. This traditional process is not at all suitable for glass stoppers that crack, break and leave in the wine shards of glass, because of the shocks they experience on the one hand between them caused by vibrations vibrator and secondly between the cap and the neck of the bottle during its introduction, either in case of misalignment, or in case of vibrations transmitted to the bottle by the motorization of the conveyor belt.

The object of the invention is to overcome these disadvantages by proposing a new automatic machine capable of closing a bottle with a glass stopper without damaging the cap or the neck of the bottle so as to avoid the accidental presence of chips of glass in the wine. This machine thus allows a support of the caps without vibration, an automatic setting up of the stopper in the bottle without contact glass-glass and an insulation of the bottle with respect to the conveyor belt during the installation of the stopper thus removing all the risks of shocks and therefore of breakage.

For this purpose, the machine according to the invention, as defined in the preamble, is characterized in that the feed device comprises a feed ramp adapted to receive the plug packaging plates, turning means adapted to return at the plugs per row, pushing means adapted to push said row of plugs in a feed chute towards the device for placing the plug and in that the device for placing the plug comprises a introduction head arranged to introduce the plug into the neck of the bottle without contact between them. Thus, it avoids the contact between the two glass parts, source of cracks and breaks of the glass.

In a preferred embodiment of the invention, the turning means comprise at least one turning drum coupled to drive means and provided with axial grooves regularly distributed on its periphery and able to receive each a row of plugs, two consecutive grooves being separated by an angle whose rope corresponds to the pitch separating two rows of consecutive plugs. Thus, the caps are handled without any vibration, avoiding shocks and the risk of breakage.

The turning means may also comprise at least one substantially cylindrical deflector disposed in extension of the supply ramp outside said overturning drum arranged to hold the plugs and guide the conditioning plate.

Advantageously, the thrust means comprise at least one actuator disposed substantially parallel to the axis of the overturning drum in the upper part and aligned with the upper groove oriented vertically and carrying the plugs at the place.

In the preferred embodiment, the feed chute extends from a high point of the overturning drum facing said upper groove at a low point of the plug placement device to allow movement of the plugs. by gravity.

The device for feeding and evacuating the bottles advantageously comprises at least one conveyor belt coupled to drive means, arranged under the device for placing the stopper and arranged to receive the bottles in a standing position, and a immobilization station arranged to position the bottle in the axis of the device for placing the stopper and to separate it from the conveyor belt.

In the preferred embodiment, the immobilization station comprises at least one pair of fixed rollers and a pair of movable rollers coupled to drive means and arranged to immobilize said bottle therebetween, and at least one fixed inclined plane provided at the edge of the conveyor belt and on which said bottle is pushed at least partially and take off from the conveyor belt during its immobilization by said rollers. Thus, the bottle does not undergo vibration due to the conveyor belt and its drive means.

The introduction head advantageously comprises at least one hollow body provided with a lateral orifice adapted to receive a stopper at the place, a central lower orifice adapted to allow the outlet of said stopper towards the bottle and a inner housing adapted to maintain said cap during its introduction into said neck and to release it at the end of its introduction.

In the preferred embodiment, the introduction head comprises at least two fingers movable radially between a rest position in which they delimit said inner housing, the head of the cap being carried by the inner edge of said fingers, and a position in which they are spaced and delimit between them a passage for the head of said cap, said fingers being biased in their rest position by return members.

Preferably, these movable fingers each comprise a cam ramp arranged to cooperate with the neck of the bottle so as to automatically cause the progressive movement of said fingers from their rest position to their working position during axial approximation of the plug with respect to the bottle or vice versa.

The profile of the cam ramp is preferably determined so that the movable fingers hold the cap at least until the seal of said cap comes into contact with said neck of the bottle. This cam ramp has in particular a concave profile variable radius arranged to accelerate the recoil of the movable fingers at the end of the plug introduction.

In the preferred embodiment, the introduction head has three movable fingers arranged relative to each other at right angles and delimiting a lateral opening facing the lateral orifice to allow the entry of said plug. These movable fingers are advantageously guided radially in said hollow body and may include means for adjusting their spacing.

The insertion head may be coupled to drive means arranged to move it between a high position in which the bottle can freely circulate and a low position on the neck of the bottle, the setting up of the cap being made between these two positions. In this case, the feed chute may have an S shape arranged to follow the movement of the feed head.

The plug feeding device and the device for placing a plug may comprise adjustment means, particularly in height, to adapt to different bottle heights.

At the immobilization station, at least the rolls of the fixed pair can be interchangeable and the stroke of the drive means can be adjustable according to the diameter of said bottle so as to align the axis of the bottle with the axis of the introductory head.

The device for setting up the stopper 2 comprises, with reference to FIGS. 1 and 5 to 7:

• An insertion head 60 formed of a hollow body provided with a substantially T-shaped lateral orifice 61 in communication with the low point of the feed chute 55 of the plugs 2, of a cylindrical axial lower orifice 62; of a diameter at least equal to that of the head 21 of the plug 2 and an inner housing 63 adapted to receive the plug 2 at the place before its introduction, this inner housing 63 having a damping pad 64 provided in part above the head 21 of the cap 2 to protect it from shocks during the placing operation,
• ◆ thrust means coupled to the introduction head 60, for example of the jack type 65, arranged to move the introduction head 60 between an upper position in which it is remote from the neck of the bottle 3 and a low position in which it covers the neck of the bottle 3, the cap 2 being introduced into the neck of the bottle 3 between these two positions without there being a contact between the foot 20 of the cap 2 and the neck of the bottle 3.

To do this, the introduction head 60 comprises at least two movable fingers and in the example shown three movable fingers 70 arranged to delimit between them the inner housing 63 adapted to receive the plug 2. These movable fingers 70 are illustrated in detail Figures 6A and 6B. They are arranged at right angles to one another and delimit between them the partially cylindrical inner housing 63 of a diameter slightly greater than the diameter of the foot 20 of the plug 2 taken under its head 21, the head 21 of the plug 2 resting on an inner shoulder 71 of the fingers 70. These three movable fingers 70 define a lateral opening 72 disposed opposite the lateral orifice 61 of the introduction head 60 to allow the plug 2 to enter. They are guided in the introduction head 60 for sliding in radial translation in their axis and are biased by a return spring 73. They are therefore movable between a rest position shown in Figures 5 and 6A in which they hold the cap 2 and the return springs 73 are relaxed, and a working position shown in Figures 7A-C in which they still hold the plug 2 but the return springs 73 are compressed, the movable fingers 70 have been pushed by the neck of the bottle 3 sliding on a cam ramp 74 provided on the movable fingers 70 under their inner shoulder 71. Figures 7A to 7C illustrate three phases of introduction of the cap 2 in the neck of a bottle 3 to visualize the sliding contact between the neck of the bottle 3 and the movable fingers 70 causing, as and when the descent of the head introduction 60, the progressive retraction of the movable fingers 70 against their return spring 73 to increase the diameter of the inner housing 63 to reach that of the head 21 of the plug 2 allowing the release of the plug 2 and its forced placement in the neck of the bottle 3 by crushing the seal 22. Figure 7C shows that the cap 2 is held by the movable fingers 70 until the seal 22 comes into contact with the neck of the bottle 2. Therefore, at no time, the foot 20 of the cap 2 does not touch the neck of the bottle 3, thus avoiding any risk of cracking or breakage of the glass of the cap 2 and the bottle 3. This cam ramp 74 preferably has a concave profile of variable radius making it possible to accelerate the recoil of the movable fingers 70 at the end of insertion of the plug 2.

This automatic machine 1 also comprises means for adjusting the position of the various devices with respect to a frame 100. With reference to FIG. 1, the feed devices 4 of the plugs 2 and of the plug positioning device 6 are mounted on trolleys 90 movable vertically along guide columns 91 by means of a screw wheel 92 for adjusting the height of the feeder 4 to the height of the delivery device 6, which itself is adjusted in depending on the height of the bottle 3 to be closed. In the positioning device 6 of the plug 2, the spacing of the movable fingers 70 is adjustable according to the diameter of the plug 2, by means of a threaded rod 75 and nuts provided on each movable finger 70, with reference in FIG. 5. The rollers 81 'of the fixed pair 81 provided at the immobilization station of the feed and discharge device 8 of the bottles 3 are interchangeable to adapt their diameter to the diameter of the bottle 3. Likewise, the the stroke of the cylinder 83 moving the movable pair of rollers 82 is adjustable according to the diameter of the cylinder 3. The radial positioning of the fixed roller pair 81 with respect to the inclined plane 84 and to the axis of the introduction head 60 is also adjustable, by screws in oblong holes for example, to be able to accurately align the axis of the bottle 3 on the axis of the introduction head 60.

This automatic machine 1 comprises a control unit 110 which can be computerized and programmable, the various devices being equipped with sensors, detectors, limit switches or any other means able to control the automatic operation of this machine.

In addition, this automatic machine 1 can be completely or partially covered according to the needs. In particular, it may comprise a closed and sealed cover covering at least the feed device 4 to the introduction head 60, in order to sterilize the plugs 2 before their introduction by spraying alcohol for example.

The operation of the machine 1 according to the invention is described below. This machine is fed into plugs 2 by directly depositing the conditioning plates 25 as they appear on the supply ramp 40 of the feed device 4. In parallel, this machine 1 is fed into bottles 3 by the conveyor belt 80 of the machine. In automatic operation, the turning drum 50 rotates step by step, each groove 51 fitting on a row of plugs 2, advancing the conditioning plate 25. The plugs 2 are maintained in their groove 51 by the deflector 41 and the conditioning plate 25 is discharged automatically at the outlet of the deflector 41. After a half-turn, the first row of plugs 2 arrives at the top of the drum 50 where it is at the place . The jack 54 of the thrust means is actuated on a stroke substantially corresponding to the length of the row of plugs 2 to send it into the feed chute 55 along which they descend by gravity to the inner housing 63 provided in the insertion head 60. As soon as the presence of a plug 2 is detected and if, in parallel, the presence of a bottle 3 is immobilized between the pairs of fixed roller 81 and mobile 82, the cylinder 65 means of thrust of the introduction head 60 is activated to move from its high position to its low position and cause the introduction of the cap 2 in the neck of the bottle 3 as explained with reference to Figures 5 to 7. After this operation, the cylinder 65 back the introduction head 60 in the high position, the movable fingers 70 return to the rest position to receive a new cap 2, the bottle 3 clogged is released from the immobilization station and the conveyor belt 80 is activated to position the next bottle 3. The cycle can continue like this continuously.

This description makes it possible to demonstrate that the machine 1 according to the invention achieves the goals set in particular that it allows the introduction of a glass stopper 2 in a glass bottle 3 automatically avoiding any risk of breakage of the glass .

The present invention is not limited to the embodiment described but extends to any modification and variation obvious to a person skilled in the art while remaining within the scope of protection defined in the appended claims.
