Description

Manufacturing line and method for operating such

production line

The invention relates to a production line for containers according to the preamble of claim 1. The present invention further relates to a method for operating such a production line according to the preamble of claim 13.

Such production lines for containers include i.a. at least one

Molding device for molding containers made of a thermoplastic material. For example, stretch blow molding machines or stretch blow molding machines, which are also referred to as blowing devices, have become known from the prior art, which are used in particular for the production of PET bottles.

In such a blowing device, the containers of a particular

Container shape of preforms, which are also referred to as PET blanks or preforms and which are in particular made of PET (polyethylene terephthalate), produced by blowing pressure. Typically, such a blower for the thermal pre-treatment of the preforms one

Heating device and a blowing device, in the region of the previously tempered preform is expanded by biaxial orientation to a container. In particular, such blowing devices have, for example, a blowing wheel rotating about a vertical machine axis with a multiplicity of blow molding stations for forming the containers from the thermally pretreated preforms. The expansion takes place with the aid of compressed air, which is introduced into the preform to be expanded. The procedural sequence in such an expansion of the preform is explained in DE-OS 43 40 291. The mentioned introduction of the pressurized gas also includes the introduction of compressed gas into the developing container bubble and the introduction of compressed gas into the preform at the beginning of the blowing process.

The basic structure of a blowing station for container molding is described in DE-OS 42 12 583. Possibilities for temperature control of the preforms are described in DE-OS 23 52 926. Within the blow molding apparatus, the preforms as well as the blown containers can be transported by means of different handling devices. Has proven particularly the use of

Transport thorns on which the preforms are attached. The preforms can also be handled with other support devices. The

Use of tongs for handling preforms and the

Use of expanding mandrels, which are insertable for mounting in a mouth region of the preform, are also among the available constructions.

A handling of containers using transfer wheels is described, for example, in DE-OS 199 06 438 in an arrangement of the transfer wheel between a blowing wheel and a discharge path.

The already described handling of the preforms takes place firstly in the so-called two-stage process, in which the preforms are first produced in an injection molding process, then temporarily stored and later conditioned with respect to their temperature and inflated to a container. On the other hand, an application in the so-called

One-step process in which the preforms immediately after their

Injection molding production and sufficient solidification suitable tempered and then inflated.

Furthermore, for example, from the document DE 603 14 627 T2, a so-called "FormFiH" method has become known in which the production of the PET bottle does not take place with compressed air, but at the in the thermally pretreated preform for forming the container a not In particular, it can be considered as not

compressible fluid, the liquid to be used to contain this bottle so as to avoid a later filling process. According to the document DE 603 14 627 T2 this is known from the prior art

Blower changed such that the fan nozzles, which are associated with the various blowing stations of the conventional blowing machine, to means for Injection of liquid and are not shot to the supply of gaseous fluid. As a result, during the expansion step, the

corresponding preform not compressed air, but introduced a non-compressible fluid.

Regardless of whether it is a stretch blow molder or an apparatus for a "FormFiir" process, each of the plurality of mold stations provided on the forming wheel for forming the actual container form from the thermally pretreated Vorfornnlingen on several form elements, each having a group of mold elements and thus the specific negative form of the

form the corresponding container shape. Here are the groups of form elements, so the respective negative forms, all provided on the form wheel

Forming stations constructed identically, so that a single bottle shape can be produced on the forming wheel with this an identical group of mold elements. Frequently, in form stations which are arranged on a rotating forming wheel, a book-like unfoldability of the form elements can be found. But it is also possible to use relatively displaceable or differently guided shape elements. In fixed molding stations, which are particularly suitable for receiving a plurality of cavities for container molding, plates arranged parallel to one another are typically used as mold elements.

Against the background of an increasing number of different bottle shapes are therefore often high performance machines that are formed in very high work cycles of tens of thousands units per hour for the production of 1000 to 2000 containers per hour and per molding station, only partially suitable because of the molding stations during operation only a single container shape can be produced. For a variation, ie modification, of the container shape, such a high-performance machine must be stopped, i. H. taken out of service, and time-consuming and costly to be converted at all forming stations of the form wheel.

It is therefore an object of the present invention to provide a production line and a method for operating such a production line for containers to provide at least one molding device for containers made of a thermoplastic material, wherein in particular the molding device as

Embodiment of the production line for containers according to the invention.

For identical or equivalent elements of the invention, identical reference numerals are used in the figures. Furthermore, for clarity, only reference numerals in the individual figures are shown, which are required for the description of the respective figure. In the figures, the invention is shown and described by way of example with reference to a production line HL for container 2, in which the molding apparatus 100 is designed to form containers 2 of a thermoplastic material as Hochleitungsblas- or Hochleistungsstreckblasmaschine and thus for the production of several tens of units per hour , So from 1000 to 2000 containers 2 per hour and per forming station 3.1, 3.2, is suitable. Likewise, however, it is also possible to design the shaping device 100 as a high-performance "FormFill" device, as shown and described, for example, in DE 603 14 627 T2.

Figures 1 and 2 show the basic structure of an exemplary first forming station 3.1 or 3.2 of a molding apparatus 100 for molding containers 2 made of a thermoplastic material by forming preforms 1 in container 2. In their respective structure, the two forming stations differ 3.1, 3.2 essentially in the form of styling of their respective form elements 5.1, 6.1, 7.1 or 5.2, 6.2, 7.2, ie the negative forms 4.1 or 4.2 formed therewith, which are only stylized in the figures.

In this case, the molding apparatus 100 for molding the container 2 more

Form stations 3.1, 3.2 for forming the container 2 from the thermal

pretreated preforms 1, which at one to a vertical

Machine axis MA rotating forming wheel 25 are arranged, as shown in more detail in Figure 3 and described. In particular, at least one first forming station 3.1 of the molding apparatus 100 has at least one first group of mold elements 5.1, 6.1, 7.1 for molding a first container mold BF1 from one of the thermally pretreated preforms 1. According to the invention, the molding apparatus 100 of the production line HL furthermore has at least one second molding station 3.2 a second group of molding elements 5.2, 6.2, 7.2 for molding a second container mold BF2 from one of the thermally pretreated preforms 1. Thus, the molding stations 3.1, 3.2 differ at least by the shape design of their corresponding mold elements 5.1, 6.1, 7.1 or 5.2, 6.2, 7.2, each having a negative mold 4.1 or Form 4.2 for the associated container shape BF1, BF2. In other words, therefore form the form elements 5.1, 6.1, 7.1 a first group of mold elements and thus a first negative mold 4.1 for a first container form BF1, while the mold elements 5.2, 6.2, 7.2 a second group of mold elements and thus a second negative mold 4.2 for form a second container shape BF2.

In this case, a thermally pretreated preform 1 can be used in the associated negative mold 4.1, 4.2 of the corresponding forming station 3.1, 3.2. Of the

Preform 1 may be an injection molded part of polyethylene terephthalate. To enable insertion of the preform 1 into the corresponding one

Negativform 4.1, 4.2 and to allow removal of the finished container 2 includes the respective negative mold 4.1, 4.2 the associated

Form elements 5.1, 6.1 and 5.2, 6.2, which may be formed as a mold halves, and the further mold element 7.1 or 7.2, each forming a bottom part and can be positioned by a corresponding lifting device 8. The preform 1 may be held in the region of the corresponding forming station 3.1 or 3.2 by a transport mandrel 9, which together with the preform 1 a plurality of

Passes through treatment stations within the device. But it is also possible, for example, the preform 1 via pliers or other

Handling means directly into the corresponding negative mold 4.1 or 4.2

use.

To enable a compressed air supply line, a corresponding connecting piston 10 is arranged below the transport mandrel 9, which supplies compressed air to the preform 1 and at the same time performs a sealing relative to the transport mandrel 9. In a modified construction, it is basically also conceivable to use solid compressed air supply lines.

A stretching of the respective preform 1 takes place in this embodiment by means of a corresponding stretching rod 1 1, which is positioned by a cylinder 12. In particular, the stretching is carried out specifically controlled for the respective first or second forming station 3.1, 3.2, which will be explained in more detail in the description of FIG. According to another embodiment, a mechanical positioning of the stretch rod 1 1 carried out over curve segments, which are acted upon by Abgriffrollen. The use of curve segments is particularly useful when a plurality of forming stations 3.1, 3.2 are arranged on a rotating forming wheel 25.

In the embodiment shown in FIG. 1, the stretching system of the respective forming station 3.1 or 3.2 of the forming device 100 is designed such that a tandem arrangement of two cylinders 12 is provided. Of a

corresponding primary cylinder 13, the associated stretch rod 1 1 is first driven to the area of a bottom 14 of the preform 1 before the beginning of the actual stretching process. During the actual stretching process, the corresponding primary cylinder 13 is positioned with extended stretching rod 1 1 together with a carriage 15 carrying the primary cylinder 13 of a secondary cylinder 16 or via a cam control. In particular, it is thought to use the respective secondary cylinder 16 such a cam-controlled that of a corresponding guide roller 17, which during the implementation of the

Stretching process slides along a curved path, a current stretching position is specified. The guide roller 17 is pressed by the secondary cylinder 16 against the guideway. The associated carriage 15 slides along two guide elements 18th

After closing in the region of corresponding carriers 19, 20

arranged mold elements 5.1, 6.1 and 5.2, 6.2 takes place a locking of the associated carrier 19, 20 relative to each other by means of a corresponding locking device VE. To adapt to different shapes of a mouth portion 21 of the preform 1, the use of separate threaded inserts 22 in the region of the corresponding negative mold 4.1, 4.2 are provided as shown in FIG. FIG. 2 additionally shows, in addition to the blown container 2, the preform 1, drawn in dashed lines, and schematically a developing container bladder 23. FIG. 3 shows a schematic block diagram of an embodiment variant of a production line HL according to the invention for containers 2 comprising at least one forming device 100 for containers 2 made of a thermoplastic material. The containers 2 are hereby produced from thermally pretreated preforms 1. For this purpose, the production line according to the invention HL have a heating section 24, the molding apparatus 100, in particular the forming wheel 25, in

Transport direction TR seen provided upstream, or arranged. The supply of identical or approximately identically formed

Preforms 1 to the heating section 24 may for example by means of a

Transfer wheels 26 take place, which conveys the preforms 1 in the transport direction TR to the heater 24, in particular passes. Along the heating section 24, a plurality of radiant heaters 30 and at least one fan 31 may be provided in order to temper the preforms 1, ie to pretreat them thermally.

By way of example, the heating section 24 for transporting the preforms 1 can have a multiplicity of circulating transport elements which are like a chain

strung together and, for example, by means of deflecting wheels are guided endlessly circulating.

After a sufficient temperature of the preforms 1, these become

For example, by means of at least one further input wheel 27 in the region of a Formradeiniaufs 25.1 passed to the forming wheel 25 of the molding apparatus 100. In the illustrated embodiment variant, the production line HL for inputting or transferring the preforms 1 to the forming wheel 25 of the forming device 100 has three input wheels 27, which convey the preforms 1 in the transport direction TR to the forming wheel 25, in particular transfer. At least one input wheel 27 can also have a schematically indicated inspection and / or

Be assigned to discharge device 28, which is adapted to detect defective preforms 1 and / or auszuschleusen, so weed out from the conveyed preform stream. For example, the inspection device 28 for detecting the preforms 1 can be designed as an optical detection device, in particular an image detection device. Furthermore, the inspection and / or Ausschleuseinrichtung 28 may also be designed to detect gaps, as defects, in the preform flow. By means of a control unit 50, with the individual Form stations 3.1, 3.2 cooperates via a respective control line 51, the corresponding forming station 3.1, 3.2, to which no preform 1 is then transported in the further course of transport, can be selectively switched off. This is what the

Control unit 50 via a control line 51 also with the inspection and / or Ausschleuseinrichtung 28 together and is for controlling and / or regulating the inspection and / or Ausschleuseinrichtung 28 and / or the forming stations 3.1, 3.2 formed.

The about a vertical machine axis MA rotating forming wheel 25 of

Shaping device 100 has on its outer circumference in preferably equal or approximately equal angular intervals, the plurality of forming stations 3.1, 3.2 for forming the container 2 from the thermally pretreated preforms 1, which may be formed, for example, according to the description of Figures 1 and 2. In particular, at least one first forming station 3.1 is schematically indicated on the forming wheel 25 with a cross-shaped symbol, which has at least a first group of mold elements 5.1, 6.1 and 7.1 for forming a first container form BF1 from one of the thermally pretreated preforms 1, while with a Hexagon symbol, the at least one second forming station 3.2 is indicated schematically, which has at least a second group of mold elements 5.2, 6.2 and 7.2 for forming a second container shape BF2 from one of the thermally pretreated preforms 1.

In particular, in each case a plurality of first and a plurality of second

Form stations 3.1 and 3.2 may be provided on the forming wheel 25 of the molding apparatus 100. Also preferred are an equal number of at least first and / or second forming stations 3.1 and 3.2 on the forming wheel 25 of

Forming device 100 is arranged. Further preferably, the first and second forming stations 3.1 and 3.2 are provided alternately, ie alternately, on the forming wheel 25 of the molding apparatus 100.

In order to be able to transform a preform 1 into a corresponding container 2 of a first and / or second container form BF1, BF2 such that the respective containers 2 of the first and / or second container form BF1, BF2 are their respective having specific matehy properties, which is a long usefulness of foods filled within the corresponding container 2,

In particular of beverages, special process steps or process step parameters must be complied with in the heating and orientation of the preforms 1 at the first and / or second forming stations 3.1, 3.2, which are formed differently, in particular at the respective first and / or second forming stations 3.1, 3.2 could be. In addition, can be advantageous

Effects can be achieved by complying with specific dimensioning rules. As a thermoplastic material different plastics can be used. For example, PET, PEN or PP can be used.

The expansion of a preform 1 during the orientation process is carried out by compressed air supply. The compressed air supply is in a Vorblasphase in which gas, for example, compressed air, is supplied at a low pressure level and divided into a subsequent Hauptblasphase in which gas is supplied at a higher pressure level. During the pre-blowing phase becomes typical

Compressed air is used with a pressure in the interval of 10 bar to 25 bar and during the main blowing phase compressed air is supplied with a pressure in the interval from 25 bar to 40 bar. Depending on the desired container shape BF1, BF2, these process parameters can be designed differently on the at least one first and the at least one second forming station 3.1, 3.2.

For this purpose, provision may be made for the at least one first and / or at least one second forming station 3.1 and 3.2 to be designed to be controllable from one another independently of stations, that is, in each case in stations.

In particular, the process parameters for shaping the

corresponding container 2 having a first and / or second container shape BF1, BF2 at each of the first and / or second forming station 3.1 and 3.2

station independent, i. station wise, adjustable trained. This is especially true for the Prozessparamater the stretching speed and the

Force curve of the stretch rod 1 1 during stretching, so for example the Station-independent control of the servo drives or electromagnetic drives for the stretch rod 1 1.

Furthermore, this also applies in particular to the station-independent, i.

stationwise, regulation and / or control of the blowing pressure and / or the

Blasvolumens and / or the blowing duration at the respective first and / or second forming station 3.1, 3.2 by means of controllable station valves and / or throttles.

For this purpose, each forming station 3.1 and 3.2 of the shaping device 100 is connected to the control unit 50 via a control line 51 shown only by way of example

Operatively connected. The control unit 50 is station independent, i.

stations, control of each forming station 3.1, 3.2 formed.

The then finally blown containers 2 of a first container form BF1 and / or a second container form BF2 are led out or removed from the respective first and / or second forming station 3.1, 3.2 in the region of a forming wheel outlet 25.2 of the forming device 100 by at least one removal wheel 29 of the production line HL and by means of the removal wheel 29 to a switch device 35, which may also be part of the production line HL passed. The switch device 35 is designed to the incoming

Container flow of the blown container 2 consisting of containers 2 at least a first and a second container form BF1, BF2 to be separated, in such a way that all containers 2 a first container form BF1 of

Switch device 35 downstream in the transport direction TR a first

Container flow BS1 and all containers 2 a second container shape BF2 of the switch device 35 downstream in the transport direction TR a second

Tray stream BS2 form. For this purpose, the diverter device 35 can interact with a first and a second transfer device 36 and 37 of the production line HL, such that the first transfer device 36 all

Container 2 a first container form BF1 and all containers 2 a second container form BF2 the second transfer device 37 is supplied, or be passed to the respective transfer device 36, 37. For example, the respective transfer device 36, 37 as a transfer wheel or transport star be educated. Switch devices for separating or dividing a container stream are well known to the skilled person. By way of example, the switch device 35 may be designed in accordance with one of the publications DEJ0007104, DEJ0008015, DE964847B, DE2801387A1, DE3007104A1 or EP191 158A2.

Consequently, after passing through the switch device 35, the containers 2 of a first container form BF1 thus form a first container stream BS1 and the containers 2 of a second container form BF2 form a second container stream BS2, wherein the two container streams BS1 and BS2 are each by means of a transporter 38.1 or 38.2 in FIG Transport direction TR are transported on. For example, the respective transporter 38.1, 38.2 of the production line HL can be designed as a conveyor belt.

It can be provided that the respective conveyor 38.1, 38.2 of the production line HL is associated with an only schematically indicated inspection and / or Ausschleuseinrichtung 39.1, 39.2, which is each adapted to detect faulty and / or wrong container 2 and / or auszuschleusen, so weed out from the promoted respective first and / or second container stream BS1, BS2. In particular, containers 2 of a first and / or second container form BF1, BF2 which have a different container shape than the remaining containers 2 of the respective container stream BS1, BS2 are understood to be "incorrect" containers 2.

For example, a container 2 with the second container shape BF2 is to be regarded as a "wrong" container 2 in the first container stream BS1, which itself only depends on

Containers 2 is formed with the first container shape BF1. For example, the respective inspection device 39.1, 39.2 for detecting the containers 2 can be designed as an optical detection device, in particular an image detection device. In this case, the control unit 50 via a control line 51 with the respective

Inspection and / or Ausschleuseinrichtung 39.1, 39.2 cooperate and be designed for the control and / or regulation of the inspection and / or Ausschleuseinrichtung 39.1, 39.2.

In the further course of the transport route, the respective containers 2 of the at least first and second container form BF1, BF2 are replaced by means of the respective Transporters 38.1, 38.2 promoted to a first and second filling machine 40, and 60 for filling the container 2 with a liquid product, which may also be part of the production line HL. In this case, the containers 2 conveyed to the first filling machine 40 can be filled with a different liquid filling material 2 to the containers 2 conveyed to the second filling machine 50. In particular, the containers 2 of the first container form BF1 are conveyed to a first container inlet 40.1 of the first filling machine 40 and the containers 2 of the second container form BF2 to a container inlet 60.1 of the second filling machine 60. The respective filling machine 40, or 60 can be designed as such a circumferential design, each with a rotor 41, 61 which is driven in rotation during the filling operation to a vertical Füllmaschineachse FMA and at its respective

Each having a plurality of filling positions 42, 62, which are supplied to the container 2 to be filled via the respective container inlet 40.1, 60.1 and the filled containers 2 are removed via a respective container outlet 40.2, 60.2 again. In this case, the control unit 50 via a control line 51 with the respective filling machine 40, 60 cooperate and for controlling and / or regulating the respective filling machine 40, 60 may be formed.

Subsequently, the filled with the same or different contents container 2 of the first and / or second container form BF1, BF2 one of
