PLANT AND METHOD FOR LAYING BOTTLES IN A TÊTE-BÊCHE ARRANGEMENT

Description

Application field

[0001] The object of the present invention is a plant and a method for laying bottles in a tête-bêche (head-to-tail) arrangement.

[0002] "Bottle" means in particular a container for liquids, mostly made of glass, of any shape, in particular of a cylindrical shape which narrows upwards into the so-called neck.

[0003] Generally speaking, "plant for laying bottles in a tête-bêche arrangement" means a plant suitable to lay bottles within a container. Such a container may be destined for packing bottles, and be constituted for example by a box or crate, or be a container for the temporary storage of bottles, intended to be subsequently transferred.

[0004] In particular, the plant and the method according to the invention are applicable to laying bottles containing wine or sparkling wine, but may be applied to laying bottles containing any type of liquid, food and non-food.

State of the art

[0005] In the wine sector in particular, there is a need to lay in a container (for packing or temporary) some types of wine in a horizontal position. Thus, in order to optimize the space within the packing box/crate or also to make the product more visible at the point of sale or to keep the content in an optimal state (i.e. to avoid the so-called cork taste in the case of wine), the bottles must be positioned with an arrangement called in jargon "tête-bêche".

[0006] A "tête-bêche" (head-to-tail) arrangement is generally understood to mean the arrangement of two things of the same kind, so that the upper part of one is facing or alongside the lower part of the other. In other words, arranging bottles in a "tête-bêche" manner means arranging the bottles side by side to each other horizontally, alternately reversing the neck-bottom orientation, as shown in Figure 1 where some bottles B are shown arranged inside a box S.

[0007] Generally, for laying bottles in a tête-bêche manner, laying systems with a gripper device mounted on a Cartesian axis movement structure are used. Such a movable gripper device is in turn equipped with a plurality of mechanical clamps suitable to grip the bottles by the neck. These mechanical clamps, placed side by side to each other, are rotatable in parallel planes. Operatively, the movable gripper device is carried on a bottle conveyor line to receive the bottles in a vertical position. Each mechanical clamp grips a bottle arranged vertically by the neck. The movable gripper device lifts the mechanical clamp with the attached bottles. During lifting, each mechanical clamp is rotated so that the relative bottle is brought into a horizontal position. Each clamp is configured to impart on the relative bottle a movement of rotation in the direction opposite to the adjacent clamps. In this way, once the rotation is complete, the bottles are arranged horizontally in a tête-bêche arrangement. At this point, the movable gripper device may transport the bottles in a laying line into containers and lay in one or more containers (e.g. boxes/packing crates) the bottles already in the tête-bêche arrangement.

[0008] An example of a bottle laying plant described above is shown in Figure 2, where A indicates the movable gripper device, E the single, orientable mechanical clamp, C the bottle transport line and D the line for laying in containers.

[0009] The laying plant described above, while fully performing its function, nevertheless has a number of limitations.

[0010] A first limitation is linked to the constructive complexity of the movable gripper device. Such device must, in effect, be able to carry out all the steps of handling and laying the bottles: from gripping the bottles to laying them in the box. Such mechanical complexity increases the cost and weight of the same movable device.

[0011] A second limitation is linked to the fact that, in the interest of containing the construction complexity, each movable gripper device is configured to act specifically on only one specific bottle format. One of the main parameters that identify a bottle format for the purpose of handling a bottle is the cross section of the bottle body, identifiable by its maximum dimension, which in particular corresponds to the maximum bottle diameter in the case of a substantially circular cross section. The fact that the movable gripper device is configured for a specific bottle format has a negative effect on the operative flexibility of the laying plant. In effect, when changing the bottle format, it is necessary to replace the movable gripper device, resulting in machine stops and operator interventions. The creation of a gripper device capable of adapting to bottle format changes would, in effect, impart further constructive complications, which would be excessively onerous in terms of increasing the cost and weight of the movable device.

[0012] From an operative point of view, the weight of the gripper device complicates replacement operations if this becomes necessary, for example, for changing the bottle format or for maintenance.

[0013] Finally, the use of the aforesaid gripper device extends the operating cycle times of the laying plant. The laying plant remains in effect in stand-by during the execution of each single cycle of operations of gripping, rotating and laying the bottles. This leads to the introduction of long downtimes.

[0014] There is, therefore, a need for a bottle laying plant with a tête-bêche arrangement that overcomes all or at least part of the limitations set out above in the solutions of the prior art (s. e.g. US 3 878 665), and in particular that allows flexible management of bottle format changes, significantly reducing the need to replace the movable gripper device, without, however, increasing the mechanical complexity of the movable gripper device.

Presentation of the invention

[0015] Therefore, the object of the present invention is to eliminate all or part of the drawbacks of the prior art mentioned above, by providing a plant for laying bottles in a tête-bêche arrangement which allows bottle format changes to be flexibly managed, significantly reducing the need to replace the movable gripper device, without however leading to an increase in the mechanical complexity of the movable gripper device.

[0016] A further object of the present invention is to provide a plant for laying bottles in a tête-bêche arrangement that is easily manageable from an operative point of view.

[0017] A further object of the present invention is to provide a plant for laying bottles in a tête-bêche arrangement that is simple and economical to implement.

Detailed description

[0019] With reference to the accompanying drawings a plant for laying bottles according to the invention has been collectively indicated at 1.

[0020] For sake of simplicity, the laying method according to the invention will be described after the laying plant 1, making reference in particular to the latter.

[0021] Here and in the description and claims that follow, reference will be made to the laying plant 1 in the condition of use. It is in this sense that any references to a lower or upper position, or to a horizontal or vertical orientation, are therefore to be understood.

[0022] The plant 1 for laying bottles in a tête-bêche arrangement according to the invention is generally suitable to lay bottles inside a container. Such a container may be destined for packing bottles, and be constituted for example by a box or crate, or be a container for the temporary storage of bottles, intended to be subsequently transferred.

[0023] According to a general embodiment of the invention, the plant for laying bottles in a tête-bêche arrangement 1 comprises:

• a device 10 for receiving bottles in input in vertical position, connectible to a bottle transport line;
• a line for laying bottles 20 in containers;
• a system 30 for positioning in tête-bêche configuration one or more groups of bottles received by the aforesaid receiving device 10; and
• a device 40 for transferring one or more groups of bottles in the tête-bêche configuration from the aforesaid positioning system to the aforesaid laying line 20.

[0024] As shown in the accompanying Figures, the bottle positioning system 30 is structurally and functionally distinct from the bottle transferring device 40.

[0025] In other words, according to the present invention, the movable device for gripping bottles present in the solutions of the prior art has been divided into two distinct systems/devices, i.e. the bottle positioning system 30 and the bottle transferring device 40.

[0026] Due to the invention, the bottle handling operations necessary to lay the bottles in a tête-bêche configuration are completely separate and distinct from the operations of transferring the bottles into the laying line. Handling operations and transfer operations are in effect carried out by operatively separate and autonomous systems/devices.

[0027] More specifically, the bottle positioning system 30 may thus be structured and sized in such a way as to carry out only the operations aimed at laying the bottles in a tête-bêche configuration, since the execution of the operations of transferring these bottles to the laying line 20 is completely entrusted to the bottle transferring device 40. Conversely, the bottle transferring device 40 may be structured and sized in such a way as to perform only the operations of transferring bottles (already in the tête-bêche configuration) to the laying line 20, since the execution of the operations aimed at laying bottles in the tête-bêche configuration is completely entrusted to the aforementioned positioning system 30.

[0028] A first advantage of such an operative separation is that it is possible to simplify the mechanical structure of the bottle transferring device 40, since it is no longer required for this device to impart the relative rotation movements among the bottles handled thereby. In effect, the bottle transferring device 40 is called to engage in gripping groups of bottles already arranged in the tête-bêche configuration. Once the bottles have been engaged, the bottle transferring device 40 may be limited to transferring them in bulk to the laying line 20 in containers. At most, the transfer device 40 may be configured to separate (divide) two distinct groups of bottles by means of a simple relative movement of translation.

[0029] Moreover, due to the fact that the transfer device 40 does not have to impart relative rotation movements among the bottles, it is possible to structure this device 40 in such a way that it may be adapted to different bottle formats (in particular, according to the maximum size/diameter of the bottle), for example by equipping it with means suitable to vary the distance provided between the components for gripping the bottles. It is also possible to use - as bottle grippers - vacuum suction cups instead of more complex mechanical clamps.

[0030] Finally, again due to the fact that the bottle transferring device 40 is not required to change the relative orientation of the bottles in order to lay them in a tête-bêche configuration, but rather only to transfer bottles already arranged in this configuration from one point of the plant 1 to another, it is possible to significantly simplify the relative support and movement structure. In particular, as will be seen later, as a support and movement structure, it is possible to adopt a robotic arm, instead of a more cumbersome system of Cartesian axes.

[0031] A second advantage of the aforesaid operative separation is that it is also possible to simplify the mechanical structure of the system 30 for positioning bottles in a tête-bêche configuration.

[0032] In effect, unlike prior art solutions, the bottle positioning system 30 is no longer required to orient bottles in a tête-bêche configuration operating suspended in the air and in movement, but rather it may carry out such manipulations operating in a "static" configuration, i.e. without requiring the system 30 as a whole to move with respect to the relative support structure. This makes it possible to structure this system 30 in such a way that it may be adapted to different bottle formats, for example by equipping it with means suitable to vary the distance provided between the components for handling the bottles. The fact that the handling of the bottles in the tête-bêche configuration is not linked to transferring also makes it possible to use - as bottle gripping elements - vacuum suction cups instead of more complex mechanical clamps. Finally, it is possible to significantly simplify also the support structure of the bottle positioning system 30.

[0033] Due to the invention, the laying plant 1 may be structured to flexibly manage bottle format changes, significantly reducing the need to replace the movable device for gripping and handling bottles, without, however, increasing the mechanical complexity of the bottle transferring device.

[0034] A third advantage of the aforesaid operative separation is that it is possible to reduce downtime in the operative cycle of the laying plant. In effect, as will be explained below, the operations of positioning bottles in tête-bêche configuration may continue even at the same time as transferring bottles into the laying line.

[0035] In general, the line 20 for laying in containers is suitable for presenting in sequence the containers within which the bottles are to be laid in a tête-bêche arrangement. As already mentioned, the containers may be packing containers (such as boxes or crates) or temporary containers. In this sense, the laying line 20 in the plant 1 may be completely traditional and is therefore well known to a person skilled in the art. It will therefore not be described in detail.

[0036] In particular, in the accompanying figures, the line 20 for laying in containers has been illustrated as a bottle packaging line. This illustration should be understood as purely illustrative and non-limiting.

[0037] According to a preferred embodiment of the invention illustrated in the accompanying figures, the aforesaid system 30 for positioning bottles in a tête-bêche configuration is associated to the device 10 for receiving bottles.

[0038] The aforesaid bottle transferring device 40 comprises:

• a movable bottle gripper head 41; and
• means 45 for moving the aforesaid movable bottle gripper head 41 in space.

[0039] Preferably, the aforesaid movement means consist of a robotic arm 45. Alternatively, it is possible to provide that the aforesaid movement means are made up of a system of Cartesian axes.

[0040] Advantageously, as illustrated in particular in Figures 5 to 11, the aforesaid system 30 for positioning bottles in a tête-bêche configuration may be structurally integrated into the bottle receiving device 10.

[0041] As already mentioned above, the bottle positioning system 30 - since it does not perform the function of transferring bottles to the laying line - does not require a dedicated support structure, which is sized to withstand the vibrations and stresses generated by the movement of large weights suspended in the air. Therefore, the bottle positioning system 30 may use the support structure of other parts of the plant, in particular of the bottle receiving device 10.

[0042] In particular, as illustrated in Figure 5, this support structure may be constituted by a support frame (such as a framework with a plurality of support legs on the ground) that defines a horizontal support surface on the top thereof.

[0043] According to the preferred embodiment of the invention illustrated in particular in Figures 12, 13 and 14, the aforesaid device 10 for receiving bottles comprises:

• two separate bottle storage lanes 11; 12, which extend parallel to each other along a bottle feed direction X and are transversely separated from each other to define a free space 17; and
• a bottle diverter 13 suitable to distribute the bottles between the two storage lanes 11, 12.

[0044] The aforesaid system 30 for positioning bottles in the tête-bêche configuration is positioned in the free space 17 between the aforesaid two bottle storage lanes 11, 12 and is suitable to act on bottles in said two storage lanes 11, 12.

[0045] Due to this configuration, the bottles arrive in the proximity of the positioning system 30, already arranged so as to be able to be picked up. This avoids therefore the need to move the bottle positioning system towards the bottles.

[0046] More specifically, the bottle receiving device 10 comprises upstream of the diverter 13 a conveyor belt 14 (or another equivalent device) suitable to impart on the bottles a translational movement along the aforesaid feed direction X from an inlet portion 15 to the diverter 13.

[0047] Operatively, the aforesaid bottle receiving device 10 is fed by a traditional bottle transport line (not illustrated) that connects the laying plant 1 to a bottling plant (not illustrated).

[0048] On the bottle receiving device 10 it is possible to define a center line M-M, substantially parallel to or corresponding to the bottle feed direction X set by the aforesaid conveyor belt 1. The two bottle storage lanes 11 and 12 extend parallel to this bottle feed direction X on opposite sides relative to this center line M-M so as to define the aforesaid free space 17, wherein is arranged the aforesaid bottle positioning system 30.

[0049] In particular, each bottle storage lane 11 and 12 is supported by a longitudinal appendage 11a and 12a of a main support structure 14a of the conveyor belt 14.

[0050] Advantageously, each storage lane 11, 12 is equipped on the outside with a longitudinal bottle containment barrier 11b, 12b, while there are no barriers on the inside facing the free space 17, to allow the bottle positioning system 30 to freely access the bottles stored therein.

[0051] Advantageously, each storage lane 11, 12 is equipped with limit stop means 16, which are suitable to limit the bottle storage area within a predefined longitudinal segment of the lane. These limit stop means 16 are adjustable. As will be clear from the description below, the longitudinal extension of the bottle storage area is chosen according to how much the operating area of intervention of the bottle positioning system 30 extends longitudinally within the aforesaid free space 17.

[0052] Operatively, the bottles B moved by the conveyor belt 14 reach the diverter 13 which directs them by sorting them into the two storage lanes 11, 12. Advantageously, the bottles move along the storage lanes 11, 12 by the pushing imparted by the bottles that progressively enter the lanes. For this purpose, preferably, the storage lanes 11, 12 are equipped with a smooth bottom (to avoid friction) or rollers.

[0053] Specifically, the diverter 13 is defined by:

• a fixed V-shaped sorter element 13a, with vertex 13b aligned with the center line M-M, and
• two adjustable walls 13c and 13d, which are placed side by side (at variable distance) to the two branches of the fixed sorter 13a to define two conveying lanes 13e, 13f of the bottles to the two storage lanes 11, 12. The position of the adjustable walls 13c, 13d is chosen according to the bottle format.

[0054] Preferably, as shown in Figures 5 to 11, the aforesaid system 30 for positioning bottles in a tête-bêche configuration comprises a plurality of bottle handling devices 31, 32.

[0055] Each bottle handling device 31, 32 is suitable to pick up a single bottle vertically from one of the two storage lanes 11, 12 of the bottle receiving device 10 (see figures 5 to 8) and position it horizontally in the space between the two storage lanes 11, 12 with the bottom-neck extension axis Y arranged transversely to the aforesaid bottle feed direction X and with neck-bottom orientation reversed relative to the orientation received by the bottles positioned by the two handling devices 32 adjacent thereto (see figures 9 to 11). In this way, the set of aforesaid handling devices 31, 32 arranges horizontally one or more groups of bottles placed side by side to each other in a tête-bêche configuration.

[0056] Advantageously, as illustrated in particular in Figures 6, 7 and 8, the aforesaid handling devices 31, 32 are organized into two distinct operating groups.

[0057] More specifically, the handling devices 31 of a first group are suitable to take bottles from a first 11 of the aforesaid two storage lanes 11 and lay them horizontally with a first neck-bottom orientation, while the handling devices 32 of a second group are suitable to take bottles from the other storage lane 12 and lay them horizontally with a second neck-bottom orientation, inverted relative to the first.

[0058] The handling devices 31, 32 of the two operating groups are arranged in alternating sequence in a direction parallel to the aforesaid bottle feed direction X.

[0059] Preferably, each handling device 31, 32 may be positioned adjustably relative to the other handling devices 31, 32 in the longitudinal direction (parallel to the feed direction X) and/or in the transverse direction (orthogonally to the feed direction X) relative to the feed direction X in order to adapt the positioning of the bottles in tête-bêche configuration to the different formats of the bottles that may be handled by the plant 1.

[0060] Advantageously, each handling device 31, 32 is movable transversely relative to the feed direction X in order to adjust the gripping distance on the bottles B arranged in the relative storage lane 11, 12.

[0061] Preferably, as provided in the embodiment illustrated in the accompanying Figures, the handling devices 31 or 32 belonging to the same operating group are movable all together transversely.

[0062] According to the preferred embodiment illustrated in particular in Figures 6, 8, 10, 11, 15 and 16, the aforesaid handling devices 31 and 32 are aligned on two separate rows F1 and F2, parallel to the aforesaid feed direction X, one for each operating group.

[0063] Advantageously, the number of handling devices 31 and 32 in each row F1 and F2 may be chosen at the design stage according to the working time of the plant 1.

[0064] Advantageously, the handling devices 31 and 32 may be divided into modular sets, which are arranged in series along the feed axis X and are suitable to act on the bottles present in the two storage lanes independently. Each modular set comprises handling devices arranged on the two rows F1 and F2, and therefore suitable to act on both storage lanes 11, 12.

[0065] More specifically, the handling devices 31 or 32 of each row F1 or F2 are associated with a relative support frame 310a, 320a, which is movable transversely to the feed direction X within the space between the two storage lanes 11, 12. In particular, each support frame 310a, 320a may be constituted by a carriage which is guided slidably by guides 340 arranged transversely to the feed direction X.

[0066] According to the embodiment shown in the accompanying Figures, the handling devices 31 or 32 in each row are kinematically associated to a worm screw 310 or 320, which is in turn associated to the respective support frame 310a or 320a and extends parallel to said feed direction X.

[0067] Operatively, the rotation of the worm screw 310 or 320 (for example by means of the relative electronically controlled motors M1 and M2) determines the axial sliding of the devices 31 or 32 associated thereto and thus their axial distribution along the worm screw 310 or 320, so as to vary the axial (longitudinal) pitch of the bottles in tête-bêche configuration.

[0068] The worm screws may be replaced by any other device suitable for the purpose, such as a rack and pinion system or a lever system.

[0069] Preferably, the handling devices 31 or 32 of each row F1 or F2 are kinematically interconnected to each other also by spacing means 311 or 312 suitable to ensure a regular spacing between the devices 31 or 32 of a same row as their axial positioning varies along the relative worm screw 310 or 320.

[0070] Preferably, as illustrated in particular in Figures 15 to 19, the aforesaid spacing means 311 and 312 consist of a kinematic chain with articulated rods, which connects the handling devices 31 or 32 of a same row F1 or F2 in sequence to each other and to some reference points.

[0071] Advantageously, the two support frames 310a, 320a of the two operating groups of handling devices 31, 32 are movable transversely to the feed direction X within the free space 17 between the two storage lanes 11, 12 in a coordinated manner using common handling means 331, 332.

[0072] Operatively, this transverse sliding may be aimed both at adjusting the gripping distance on the bottles B placed in the relative storage lane 11, 12, and at varying the transverse pitch of the bottles in tête-bêche configuration.

[0073] In particular, as illustrated in the accompanying Figures, and in particular in Figures 15 to 19, each worm screw 310 or 320 is associated to a respective support frame 310a or 320a, slidably guided by guides 340 arranged transversely to the feed direction X. In turn, each of the two support frames 310a and 320a is kinematically associated to a worm screw 331 and 332, arranged with its axis transverse to the feed direction X. The two worm screws 331 and 332 have opposite threads (one clockwise and the other counterclockwise) and are joined together centrally. Operatively, the rotation of one of the two worm screws 332 (e.g. by means of the associated electronically controlled motor M3) is transmitted to the other worm screw 331 and collectively determines the axial sliding of the two support frames 310a and 320a in opposite directions (due to the inverted threading of the two screws), thus allowing the two support frames 310a and 320a to be brought closer together or further apart in a coordinated manner in a transverse direction.

[0074] Preferably, as illustrated in particular in Figures 20 to 23, each bottle handling device 31, 32 of the aforesaid bottle positioning system 30 comprises a bottle gripper element 33, which is movable, preferably by rotation, between:

• a bottle pick-up position, wherein the gripper element 33 is positioned vertically near the relative bottle storage lane 11, 12 to pick up a bottle by gripping it (see Figures 5, 8, 20, 21), and
• a bottle orientation position, wherein the gripper element 33 is positioned horizontally to position a bottle taken from its storage lane 11, 12 horizontally in the space between the two storage lanes 11, 12 (see Figures 9, 11, 22, 23).

[0075] According to the embodiment shown in the accompanying Figures, each bottle handling device 31, 32 comprises:

• a support frame 35, to which the gripper element 33 is rotationally associated;
• a kinematic coupling base 36 to the respective worm screw 310 or 320, to which the support frame 35 is attached; and
• an actuator 37, suitable to push the gripper element 33 to cause the rotation thereof relative to the frame 35.

[0076] In particular, the support frame 35 consists of an L-profile with a first horizontal portion 35a for fixing to the base 36 and a second vertical portion 35b for pivoting the gripper element 33. The frame 35 is associated to the actuator 37 (preferably consisting of a pneumatic cylinder).

[0077] Preferably, as illustrated in the accompanying Figures, each bottle gripping element 33 is suitable to grip a bottle with at least one vacuum suction cup 34.

[0078] The use of vacuum suction cups as gripping elements is made possible in that the handling devices 31 and 32 are called upon to orient the bottles in a static operating condition, i.e. in an operating condition not associated with a simultaneous movement of the entire handling device.

[0079] As already mentioned above, according to a preferred embodiment illustrated in the accompanying figures, the device for transferring bottles 40 comprises:

• a movable bottle gripper head 41; and
• means 45 for moving in space the aforesaid movable bottle gripper head 41.

[0080] Advantageously, as illustrated in particular in Figures 24, 25 and 26, the aforesaid movable bottle gripper head 41 comprises a plurality of gripper elements 42, each of which is suitable to grip a bottle B.

[0081] More specifically, the aforesaid gripper elements 42 are distributed on two parallel rows L1 and L2 to grip one or more groups of bottles B already arranged in tête-bêche configuration.

[0082] Advantageously, each bottle gripping element 42 is suitable to grip a bottle by means of at least one vacuum suction cup 43.

[0083] The use of vacuum suction cups as gripper elements in the movable bottle gripper head 41 is made possible in that this movable head 41 is not required to change the relative orientation of the bottles to arrange them in tête-bêche configuration, but only to transfer bottles already arranged in such configuration from one point to another of the plant 1.

[0084] Advantageously, the gripper elements 42 of each row L1 and L2 are movable in relation to each other so as to adjust the pitch and thus adapt them to the bottle format. This may be achieved in a constructively simple way due to the fact that vacuum suction cups, and not mechanical clamps, may be used as gripper elements.

[0085] Preferably, as shown schematically in Figure 4, the laying plant 1 is automated and comprises an electronic control unit 100 which is programmed to control at least the bottle positioning system 30 and the bottle transferring device 40 so that, while the bottle transferring device 40 is transferring one or more groups of bottles B in the tête-bêche configuration towards the laying line 20 picked up by the bottle positioning system 30, the bottle positioning system 30 is preparing one or more groups of bottles in the tête-bêche configuration.

[0086] As shown above, this reduces downtime in the operating cycle of plant 1.

[0087] The method of laying bottles in a tête-bêche arrangement according to the invention will now be described.

[0088] This laying method is implemented by means of a laying plant 1 comprising:

• a line for laying bottles 20 in containers.

[0089] Preferably, the laying method is implemented by means of a laying plant 1 according to the present invention, and in particular as described above.

[0090] More specifically, the method according to the invention comprises the following operative steps:

• a) positioning in the tête-bêche configuration one or more groups of bottles B received by the aforesaid receiving device 10; and
• b) transferring one or more groups of bottles in the tête-bêche configuration in the bottle laying line 20,

[0091] According to the invention, the aforesaid step a) of positioning bottles is implemented by a system 30 to position one or more groups of bottles in tête-bêche configuration, while the aforesaid step b) is implemented by a device 40 to transfer one or more groups of bottles in tête-bêche configuration into the line for laying in containers.

[0092] The bottle positioning system 30 is structurally and functionally separate from the bottle transferring device 40.

[0093] Preferably, the bottle positioning step a) is carried out at the same time as the execution of the transferring step b) on at least one group of bottles different from that on which said transferring step b) is being performed.

[0094] The advantages offered by the invention already highlighted above when describing the laying plant 1 also apply to the laying method and will not be repeated here for brevity of description.

[0095] The invention allows many advantages already partly described to be obtained.

[0096] The plant for laying bottles in a tête-bêche arrangement according to the invention allows flexible management of bottle format changes, significantly reducing the need to replace the bottle transferring device in the laying line, without, however, increasing the mechanical complexity of such bottle transferring device.

[0097] The bottle laying system according to the invention is moreover easy to manage from an operative point of view.

[0098] Finally, the bottle laying plant according to the invention is simple and economical to implement.

[0099] The laying plant 1 may be structured to flexibly manage bottle format changes, significantly reducing the need to replace the movable device for gripping and handling bottles, without, however, increasing the mechanical complexity of the bottle transferring device.

[0100] The invention thus conceived therefore achieves the foregoing objects.

[0101] Obviously, in its practical implementation, it may also be assumed to take on embodiments and configurations other than those described above without departing from the present scope of protection.

[0102] Moreover, all details may be replaced by technically equivalent elements, and the dimensions, shapes and materials used may be of any kind according to the needs.
