Description

Online bottling plant.

The present invention relates to improvements to online bottling facilities compre¬ essentially ing a container manufacturing unit, in particular bottles, made of thermoplastic material, a filling unit of the aforementioned containers and a conveying unit for containers coming from be manufactured interposed between the output of the said unit making tainers réci¬ and the inlet of the aforesaid containers filling unit.

To feed the bottling plants in containers to be filled, it is known to manufacture said containers in a geographic manufacturing unit ent remote from the bottling unit, with a transportation and / or containers from railway unit making up the manufacturing unit to the filling unit.

To avoid the difficulties inherent in long-range transport of containers from the production unit to the filling unit, it is also known to install the manufacturing unit near the unit and transfer wise remplis¬ the containers of the first to the second by means of a conveying device.

However, it was then found necessary to provide a buffer between the manufacturing unit and the filling unit, so as to mitigate the impact on one of the units, the pause of the other unit due to a short-term incident. To this end, the con¬ trip device has been designed as a conveyor of very Gran- of developed length, up to 500 m or more, which may correspond to a volume of several thousands of containers.

Now, such a conveyor device occupies considerable space. It is therefore doubly costly, both in hardware and area occupied, and all the more so that its length is important. Although we knew the match tif provi- conveying at least part of air way to free up floor space, but the advantage obtained is minimal.

In addition, maintaining a conveyor device of such great length in reliable operating condition is difficult and expensive, the difficulty and cost again being even higher than the conveyor device is long.

the length of the conveyor was attempted certainly reduced and the area occupied by the conveyor device by making compact devices for temporary storage of empty containers, which are managed so as to regularize containers of the flow between the affinity of manufacture and filling unit. However, these storage devices have insufficient storage capacity for the establishment and economy entre¬ yours the conveying device takes place feel significantly. In addition, these storage devices are themselves expensive to produce and require mainte- nance, so they were not provided, finally, the expected benefits.

Another drawback of conveyors used lies in the possibility of damage to at least some of the transported container. Indeed, it is widely used in the installations considered, conveyors pneumati¬ c which implement a succession of air jets acting on the container, in particular on the collar thereof guided between two rails, which container, being empty and light, is then propelled at high speed. However, the empty container is easily deformable and, if it comes to hit an obstacle (e.g. a preceding container stopped or moved less rapidly), it may undergo itself and / or cause the previous container damage, e.g. deformation such as a depression at the level of the shoulder; it can result in a loss of symmetry of the vessel which may result in its inclination relative to the vertical for example, and such a container is no longer able to be properly grasped in the filling unit, which causes an operating incident thereof. Unacceptable deformation of the same kind can also affect containers transported over great distance between geographically remote units.

Also, consider that some damage to vessels led to a significant financial loss. The individual cost of a container is admittedly low, but the impact of the presence of a faulty container which requires even stop short of installa¬ tion, or at least of the filling unit, then put implementation of a restarting process, resulting in a substantial deficit in the number of filled containers collected trailing, and therefore a shortfall which, in total, appears sensible.

Another disadvantage which affects the containers regardless of the type of installation lies in the risk of internal pollution of the containers which are moved unclosed between the manufacturing unit and the filling unit and that remain closed during a duration which can be very long in the case of a storage intermé¬ intermediary of finished containers between manufacture and filling. To avoid the risks posed by such pollution, it is customary to provide a container of rinsing unit immediately upstream of the filling unit. Such flushing unit proves, again, expensive to purchase, maintain and use and requires also a place for his installa¬ tion.

Given the difficulties and disadvantages attached to the current facility, there is a pressing demand for a more economical system both technically and financially, that is to say an installation that is less demanding in place and equipment, which means less damage réci¬ tainers brought to the entrance of the filling unit and thus lower losses during production, and which generally is more economical than facili- ties current.

To this end, the invention provides a line bottling plant as mentioned in the preamble which, being arranged according to the invention are caracté¬ rise essentially in that the container manufacturing unit and the unit filling of the containers are arranged at as short a distance as possible from one 1'autre and the conveying unit has a short length and is arranged to move following the containers from one another without the containers being subjected to serious impacts especially against each other.

With this arrangement, the area occupied by conveyor 1'unité is reduced so considéra¬ ble; the cost of the constituent material of the conveyor unit and the cost of implementing this system are therefore also considerably reduced. Similarly, the risks of operating incident of this conveyor unit and the maintenance costs are lower. Generally speaking, installation and running costs of the conveying unit are made to decrease as the distance between the outlet of the container forming unit and the input of the unit filling is less.

The short distance transportation of the containers also makes it possible to arrange the conveyor in any desired manner. It is then possible to maintain an air jet conveyor structure which can, given the small distance, be set to move the containers with a rate corresponding to the operation of the manufacturing unit speeds and of the filling unit, and in any case this rate is considerably less than that practiced in very long conveyors used actuelle¬ lying. Under these conditions, even if the containers collide, the shocks do not have a clean violence engen¬ drer deformation. Thus away because of a disfonc- tioning of the filling unit.

Always because of the short length of the conveyor unit, the duration of the transfer of containers from the outlet of the manufacturing unit to the inlet of the filling unit is low: thus considerably reduces the risk of an internal pollution of the containers prior to entry into the filling unit and it becomes possible to dispense with the pre-rinsing machine which was necessary until now. The result, again, a substantial saving in material, in place, washing liquid and maintenance, and therefore a significant financial saving.

But the low transport distance also makes it possible to implement, in conditions of installation cost and acceptable operation, a clean mechanical tor transported to move the containers mainte¬ ing them to no predetermined spacing, for example an endless chain conveyor and gripper; it is easy to ensure that the containers are gripped at the outlet of the manufacturing unit and discharged with a substantially identical velocity to the speed at which the manufacturing unit delivers the finished containers, and so it is easy to ensure that the containers are presented to the input of the filling unit with a substantially identical speed to that of operation of the filling unit. It is therefore advantageous to provide synchronizing means adapted to synchronize the respective operating speeds of the manufacturing unit, of the conveying unit and the filling unit. It is also advantageous that the pitch of the containers at the outlet of the manufacturing unit, during displacement in the conveying unit and the filling unit input are substantially equal.

The short length of conveying of the containers, if it has many advantages as explained above, however, may cause a drawback in case of malfunction of even short duration of the filling unit (whether of a problem in the filling unit itself or, more commonly, from an incident occurring downstream thereof, for example the position of éti- ging or packaging station). Indeed, the absence of a temporary storage of containers "between the manufacturing unit and the filling unit while committing should result in stopping the process unit. This would result in the loss of production of containers being who would be blocked in the heating furnaces and would be irretrievably lost because the constituent thermoplastic material being processed then suffer uncontrolled overheating; financial loss due to the destruction of the containers contained simultaneously in the manufacturing unit (which can reach several hundred units in installa¬ largest tions) is not negligible and should therefore be avoided. Especially it would also result in an alteration of certain components or parts of the heating means or their damage, which must be avoided at all costs.

It is therefore desirable that the installation is arranged such that, during a stoppage of the filling unit, the manufacturing unit can temporarily continue to function so that, before the production unit to be shut down turn the oven (or ovens) heating is emptied to avoid the aforementioned drawbacks and / or a reserve of finished containers to be made to facilitate the re-operation of the plant, as explained below.

To this end, it is expected that the installation according to the invention may further comprise a temporary retention unit containers which is selectively connectable to the conveying unit and which is arranged to receive and retain a number of containers. It is interesting that the retaining unit is also arranged so that the displacement of the containers one after another takes place without said containers being subjected to serious impacts.

To avoid, as mentioned above, any risk of damage or heating furnaces and a significant loss of containers can then be advantageous if:

- if the manufacturing unit comprises at least one furnace for heating preforms situated upstream of a molding device of hot preforms, then the retaining unit retaining capacity is approximately equal to the number of containers simultaneously present in the heating furnace, so that, in case of stoppage of the filling unit, the manufacturing unit can be kept in operation until the heating furnace has been emptied,

- if the manufacturing unit comprises a plurality of heating furnaces situated upstream of respective molding devices, then the retaining capacity of the retaining means is approximately equal to the number of tainers réci¬ present simultaneously in the manufacturing unit between the input of the first furnace and the outlet of the last oven, so that in the event of stoppage of the filling unit, the manufacturing unit can be kept in operation until all the heating furnaces have been emptied.

In either case, it is also envisa¬ ger that the retaining means holding capacity is approximately equal to the number of containers simultaneously present in the whole of the manufacturing unit, so that, event of stoppage of the filling unit, θ the manufacturing unit can be kept in fonctionne¬ ment until it is emptied in full screen.

In combination with the above or independently, the presence of a reci- tainers holding unit within the installation may also be desirable to facilitate the functioning of the installation. Indeed, when the installation was stopped only for a short period of time, for example due to some serious incident, the oven (or ovens) for heating the manufacturing unit did not have the time to cool significantly and container manufacturing unit can then restart substantially instantané¬ ment, together with the filling unit. Against by, after a period of relatively long or very long, the heating furnace has substantially cooled and a preheating time must be allowed before the manufacturing unit can be capable of producing finished containers again while the filling unit is, for its part, ready for use immediately. In this context, it is interesting to bring in the containers holding unit and to provide that the ability of the latter is at least equal to the number of containers required for the operation of the filling unit, upon delivery in operation of the installation, for a period required to put into operation (reheating time) of the manufacturing unit.

In a preferred embodiment, the retaining unit comprises a conveyor connectable open loop sélecti¬ vely by its inlet end and / or via its outlet end to the conveying unit and having a length making it suitable for receive the above containers arranged one after the other one. A well arranged holding unit can be compact enough not entraî¬ ner excessive cost. The selective connection of the aforementioned conveyor with the conveyor unit can be carried out using switching means interposed between the conveying unit and the inlet end of the retaining unit and between the unit conveyor and the outlet end of the retaining unit. Since these switching means are not functionally active during the time of their switching from one position to the other-that is to say that they are then not able to ensure the guiding, to the appropriate destination , containers which would arise during this time commutation- can be provided advantageously to avoid any incident of operation, the containers surve¬ ing during this switching time of the circuit are ejected with ejection means containers associated with said switching means.

It is also possible ejection means and / or stop situated upstream of the oven to eject and / or stop the containers (preforms or intermediate containers) which are supplied to the furnace or furnaces while the unit filling is no longer in operation. This avoids, during the emptying phase of the oven as a result of a stoppage of the filling unit, to continue to feed the production unit at the time when it will be stopped in turn.

Finally, it is noted that the short length of the conveyor unit may cause difficulty for the cooled dissement containers newly manufactured which leave the manufacturing unit still being significantly hot. Up to now, containers cooling intervened between the output of the unit of manufacture and their introduction into the filling unit, is due to intermediate storage, or because of the length size of the intermediate conveyor. For against, in the installation of the invention, the short length required for the conveying unit that the containers may be brought still hot in the filling unit, which does not qualify for the retained ¬ qualities of the filling liquid or the mechanical strength of the containers (deterioration, deformation, ...). It is then very desirable that the conveyor unit are associated means of cooling at least a portion, including at least the bottom (usually thicker part thus naturally cools more slowly), outgoing containers of the manufacturing unit. The implementation of such cooling means, which may be reduced to a single blower may not result in a significant additional cost of installation and maintenance. Finally, a system arranged in accordance with the invention differs, by virtue of its compactness, the many drawbacks of previous systems and is particularly interesting in terms finan¬ cer whether for materials used for its implantation, for its operation and maintenance. The invention will be better understood from reading the following detailed description of certain réalisa¬ tion modes given solely by way of examples limita¬ tif. In this description, we refer to the accompanying drawings, wherein:

- Figure 1 illustrates very schematically an installation structure arranged according to the invention;

- Figure 2 illustrates another embodiment wherein of the Figure 1 installation is completed by a container holding unit; and

- Figure 3 illustrates another embodiment wherein the plant of Figure 2 is completed by a number of ancillary devices.

The installation shown in Figure 1 essentially comprises a unit 1 for manufacturing containers, such as bottles, made of thermoplastic material, a unit 2 for filling said containers, and a unit 3 for conveying containers made from the output 4 of the unit 1 to manufacture the inlet 5 of the filling unit.

The manufacturing unit 1 may be of any type suitable for the manufacture of containers, such as bottles, made of thermoplastic material such as polyé- thylènetherephtalate PET, polyethylene naphthalate PEN or other. It receives, at its input, preforms amorphous material from a unit 7 for supplying the preforms. The unit 7 may consist of a hopper 8 receiving bulk preforms made by molding prélablement and in another location, which hopper is connected to the inlet 6 via a sorter 9 which isolates and positions the preforms on a slide 10 connected to the inlet 6 of the manufacturing unit (cold preform feed) as shown in Figure 1. the unit 7 may also consist of the molding unit of the preforms itself which delivers the preforms to be molded from and still hot directly to the inlet 6 of the manufacturing unit (hot preform feed).

The treatment of the preforms within the manufacturing unit may be any and for the type of containers to be produced (single or double blowing single or multiple heat treatment, ...). Figure 1 is reproduced, for reasons of simplicity and clarity, a simple treatment of the preforms which are mounted at 11 in a transfer line 12 and then heated to show in a tunnel oven 13 before being taken up in 14 to be introduced hot into a device 15 for blowing or stretch-blow molding multiple molds on a carousel. After controlled cooling, the containers which have just been made are presented at the output 4 of the manufacturing unit 1. The containers received at the input 5 of the filling unit 2 are arranged on a drum filling device rotating 16 from which, once filled, they are extracted and presented to a closure device 17. the filled containers are then stoppered and evacuated through the outlet 18 of the filling unit 2, to a labeling station and a wrapping station (not shown). The container manufacturing unit 1 and the filling unit 2 are arranged as close as possible to each other so that the distance between the outlet 4 of the first and the inlet 5 of the second is also low as possible. The conveying unit 3 which extends from the aforesaid outlet 4 at the aforesaid inlet 5 is short and 1'introduction containers from the conveying unit 3 in the filling unit 2 is carried out directly without through a washing device useless because of the risk now very small inner containers pollution. Given its low lon¬ LATIONS, the conveying unit 3 can certainly be of the air jets such as very long employed carriers devices in existing facilities, but can also be performed in economically acceptable conditions in the form of an endless chain conveyor device, for example clamps which is able to transport the containers with no constant deviates ent. The operating speed of the conveying unit

3 can easily be adjusted in correspondence with the containers of the feeding rate at the outlet 4 of the manufacturing unit 1 to the intake speed of the containers at the inlet 5 of the filling unit. Here, note that improvements can be made to the filler units conferring a filling capacity which has become the same order of magnitude as the manufacturing capacity of the blower units. Thus, a filling unit can now be supplied with containers to be filled from a single unit fabrica¬ tion vessel, so that a single conveyor unit is expected to meet to each other . This results in a considerable simplification of the General for concep¬ installation and greater compactness for a given producrion rate.

also it will be noted in this connection that the means implemented in an installation according to the invention condui¬ feels less of operating incidents risk and therefore allow very high production rates. The invention therefore is a privileged field of application in systems able to produce and fill tens of thousands of containers per hour.

Given the levels of identical quantities of the operating speeds of the container manufacturing unit 1 and the filling unit 2, it is possible to envisage an operation timing of these two units and further the operation of the 'conveyor unit 3, so that the flow of containers leaving the manufacturing unit coincides perfectly with the flow of containers admitted into the filling unit, which prevents any container catch-up phenomenon being transferred. a cause of damaging the containers thus deviates and thus also a cause of incident and possible stoppage of the filling unit.

Preferably, as shown in Figure 2, is provided to add to the conveying unit 3 a temporary retaining unit 19 that is arranged for receiving, temporarily retaining and returning a number of containers. It is desirable that the holding unit is, also, arranged so that in the movement of the containers one after another takes place without said containers being subjected to serious impacts.

To avoid the loss of the corresponding containers overheated standing still in front of the heating means and also to prevent alteration or damage of said heating means, it is desirable that the manufacturing unit still fonction¬ ner after a filling unit stop so as to complete at least a current heating cycle. Thus, when the manufacturing unit comprises at least one furnace for heating preforms situated upstream of a hot preform molding device, it is expected that the retaining unit retaining capacity is approximately equal to the number of containers simultaneously present in the heating furnace, so that, in case of stoppage of the filling unit, the manufacturing unit can be kept in operation until the heating furnace has been emptied. Similarly, when the manufacturing unit comprises a plurality of heating furnaces situated upstream of respective molding devices, it is expected that the retaining unit retaining capacity is approximately equal to the number of containers simultaneously present in the unit production between the inlet of the first furnace and the outlet of the final furnace, so that, in case of stoppage of the filling unit, the manufacturing unit can be kept in operation until all the ovens heating are emptied.

Moreover, particularly in the case where the manufacturing unit implements a multiple molding process, for example a double-blowing process and / or stretch blow involving several heating steps, it is then simpler to consider completely emptying the manufacturing unit of all containers being processed are simultaneously present there at the time of filling 1'unité stop: the retaining unit must be arranged to be able to accept this number of containers can be relatively high. To fix ideas, high capacity production unit contains an order of magnitude of about 500 containers being processed at various stages; the body of a completed container having a diameter of about 10 cm, the queue of such containers side by side against each other has a length of approximately 50 meters. It will therefore be necessary to provide a holding unit having a length of about 50-60 meters, which, from the viewpoint of orders of magnitude, corresponds to a developed length ten times less than that of the conveying means buffer function used in previous installations. The holding unit 19 may comprise a carrier 20 extending in an open loop between an inlet 21 and an outlet 22 that are selectively switchable on the conveying unit 3. The open loop formed by the conveyor 20 has a developed length own receiving the aforementioned number of containers, which can reach several hundred for larger production units. Under these conditions if stoppage of the filling unit 2, it can complete emptying the manufacturing unit 1 (in its interrupt the running preform feed) so that all the containers during manufacture, which are present in the manufacturing unit 1 at the time of stoppage of the filling unit 2, can be retrieved completed and ready to be used at the restart of the plant. This prevents the waste of a considerable number of containers and especially avoids fouling or damage to the manufacturing unit that could occur when stopping of it still filled containers being manufactured. Furthermore, as a result of a too long cooling stop driving the heating means, the manufacturing unit can not start producing containers after a warm-up period. To overcome the disadvantage of such a delay with respect to the filling unit, which itself may be restarted instantaneously, it is conceivable that the retaining unit has sufficient capacity to be able to powering the filling unit back into operation first, pending completion of the preheating. To ensure the passage of the containers from the conveying unit 3 of the retaining unit 19 and vice versa, it is expected to have the switching means between the conveyor unit 3 and the inlet end 21 of the holding unit 19 and / or between the conveying unit 3 and the outlet end 22 of the holding unit 19. However, these switching means has a response time and are not capable of guiding the containers safely during switching phase. To avoid problems in case of arrival of containers during this switching phase, is provided, as shown in Figure 3, to associate containers ejection means to these switching means, at least those located the inlet 21 of the retaining unit as referenced 23 in Figure 3, so that the containers are ejected occurring during the switching phase. Similarly, it may be advantageous to provide ejection means or stop means (e.g., a cleat across the feed passage), designated 24 in Figure 3, upstream of the oven heating the manufacturing unit to eject or stop the containers (preforms, intermediate containers) which are supplied to the (x) furnace (s) while the filling unit is no longer in operation. The manufacturing unit then being still kept in service to complete the containers during manufacture as mentioned above, and it is ensured that no new preform or intermediate container is again introduced into the (s) furnace (s).

Finally, for the containers (still warm out of the manufacturing unit) are introduced cold into the filling unit in spite of the length as small as possible to the conveying unit 3, can be associated with the latter means 25 of all or part cooling, and especially the bottom of the containers leaving the manufacturing unit. The cooling means 25 may be located at the outlet of the manufacturing unit, and even extend to the entrance of the unit wise remplis- if necessary. These cooling means can be made in any suitable manner, from a single cross-flow fan to the conveyor, inexpensive, to a tunnel type equipment with blowing cold air or cold gas countercurrent to the movement of containers , more effective but more expensive.

As is evident and as it already follows from the foregoing, the invention is not limited to those of its modes of application and embodiments which have been specifically considered; it encompasses all variants.
