Description

The present invention relates to a device for cleaning plastic containers and in particular plastic preforms and to a method for operating a device for cleaning plastic preforms. Such devices and methods for cleaning hollow bodies and in particular plastic preforms have long been known from the prior art. Usually, the preforms are thereby blown out for cleaning by means of a gaseous medium, so that in particular dusts and other impurities contained in the preform are removed from the interior of the preforms in order to avoid contamination of the product during the subsequent filling process.

The preforms are usually transported by means of a transport device to the cleaning device, which is preferably a rinser. Furthermore, these devices comprise at least one and preferably a plurality of Rinsdüsen which clean the plastic preforms and in particular blow out a cavity of the preforms with a gas stream.

However, it is disadvantageous in the prior art that only a predetermined design of the rinser is available, so that can not be flexibly addressed to specific customer requirements. Furthermore, so far no "modular principle" is possible with which, even with changing requirements, existing cleaning devices can be extended or changed.

The present invention is therefore based on the object to provide a flexible device and a flexible method with which / with which a situation-dependent adaptation of the device can be made in a simple manner. These objects are achieved according to the invention by the subject matters of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.

According to the invention, the device for cleaning plastic preforms is constructed in modular construction.

In this case, a modular construction is understood in particular to mean that the device has a number of standardized mechanical and control-side connection and interfaces to which any devices and / or elements can be attached and also removed, these devices and / or elements also being standardized have mechanical and control-side connection and interfaces, which are compatible with the connection and interfaces of the device. In particular, the device consists of a basic or basic module, which can be supplemented arbitrarily, and in particular even after the installation of the base module, by further devices, functions, elements and / or components without that thereby the function or operation of the Basic module is limited or endangered.

In a modular design or a so-called modular principle, therefore, an entire system is divided into several parts, so-called modules, wherein the individual parts / modules fulfill different functions or perform different treatment steps on a product. It should be connected to a basic module in particular depending on wishes and / or requirements any modules connectable and removable. In order to make this possible, mechanical and / or electrical interfaces corresponding to one another are arranged both on the basic module and on the individual parts.

For example, therefore, the basic module of the device for cleaning plastic preforms has a first interface, and a module, which may be a holding device, a turning station or a control unit, as will be explained in greater detail below, has a second interface. The first interface and the second interface allow both a mechanical connection and an electrical connection between the modules connected by these interfaces, for example between cleaning device and holding device, such that both the holding devices can be arranged on the cleaning device, as well as between the cleaning device and the holding means at least one further module, such as a turning station can be integrated.

It is therefore proposed according to the invention to build the device for cleaning plastic preforms as a modular or modular principle to provide high flexibility in the To achieve equipment and the desire for a higher cleaning performance even after the fact by installing or remodeling the machine to ensure. The individual embodiments can also be realized later, because the basic structure is always the same. The basic structure has uniform connection points and is therefore compatible with any extension packages. As a result of the various embodiments of the cleaning device according to the module principle, it is also possible to achieve a wide variety of cleaning levels, for example, by exchanging any cleaning devices, depending on the customer's wishes.

The device according to the invention and the method according to the invention accordingly have the particular advantages that, as a result of the modular principle, a high degree of flexibility in customer requirements is made possible, whereby even later wishes arising after the purchase can be met. In particular, a simple exchange or a simple addition of components is made possible by the modular construction according to the invention as well as an optimal adaptation of the required cleaning functions to the required different cleaning requirements. Further advantages are that a significant reduction in costs for production can be achieved by a single base frame for all variants.

The device for cleaning plastic preforms is preferably a so-called rinser or a rinser unit. Preferably, the device for cleaning the plastic preforms or the rinser upstream with respect to a blow molding machine, which transforms the plastic preforms into plastic containers, is arranged. The gaseous medium is preferably compressed air. It is also conceivable that the gaseous medium is a sterile gaseous medium, so that no further contamination is caused on the preforms. The transport device is preferably a sawtooth star or a pocket star. The holding devices are preferably gripping devices or clamps which grip or hold the preforms in an opening region and preferably below a support ring.

The rinsing unit is preferably designed as a stand-alone machine, that is to say that the rinsing unit is not coupled to or synchronized with subsequent or preceding machines. Preferably, however, the rinsing unit has a connection system for integration into a machine block. The connection system is preferably mechanical, electrical and / or control technology interfaces.

In a preferred embodiment, the at least one loading device is a rinsing nozzle and preferably a static or stationary nozzle. With a static arrangement of the loading device, the preforms are preferably moved away under the loading device and thus cleaned. In such a stationary rinsing nozzle, the plastic preforms are preferably in an upright position, i. with their mouths up, transported.

In a further preferred embodiment, the at least one loading device or the rinsing nozzle is at least temporarily movable during the transport of the plastic preforms with the plastic preforms. By a moving nozzle, compared to a stationary nozzle, significantly longer process or Rinserzeiten possible, resulting in an overall better rinser results.

In a further particularly preferred embodiment, the at least one loading device or the rinsing nozzle with the plastic preforms is mitbewegbar and is introduced into a mouth region of the plastic preforms. By means of such a moving and immersing rinsing nozzle, the highest cleaning results can be achieved, in particular with very fine and light particles. The nozzle position during insertion of the rinsing nozzle into the plastic preform is preferably controlled via a mechanical, hydraulic, pneumatic or similar device suitable for this purpose. In particular, the height of the nozzle head during the process start, before the actual process and during the process, is preferably detected. Preference is given to the immersion depth of the nozzles in the preform and preferably the mouth of the preform is set to selectively, depending on Vorformlingtyp to achieve an optimal cleaning result and to be able to guarantee.

Compared to static rinsing nozzles, the degree of cleaning of the preforms can therefore be increased enormously when the nozzles are moving, since a preform is cleaned there for a longer time through a nozzle. Both when using a static nozzle and when using a moving nozzle, the preforms are preferably cleaned during the transport of the preforms.

Preferably, the plastic preforms, if it is a traveling nozzle or a moving and submerged nozzle, overhead, i. transported with the mouth down.

In a further preferred embodiment, the device has at least one Turning station, wherein the holding devices are arranged at this turning station and the plastic preforms by means of this turning station tiltable by 180 ° and / or are rotatable about a longitudinal direction of the plastic preforms. Particularly preferably, the device has a plurality of such turning stations. In this case, the turning station is preferably a module according to the invention, which can be arranged on the device as required.

By the turning stations is thereby made possible that the preforms can be cleaned in an inverted position and preferably from all sides, which in particular a better cleaning result can be achieved. In particular, this allows a full cleaning of the plastic preforms. By turning active, in particular heavy particles can be removed safely, which in turn leads to better rinser results.

As will be explained in more detail in the figures, the above-mentioned components or modules can arbitrarily be added to a base module, removed, expanded and replaced. The base module or the uniform base frame of the rinser preferably comprises a platform for the rinser, the rotatable carousel, the holding devices and brackets for the holding devices, the transport device and at least one and preferably a plurality of rinsing nozzles. It is therefore preferred for all embodiments uses a single base frame, whereby the series production is simplified and based on the module design all variants can be executed and even combined.

Preferably, the rinser is designed such that, depending on the module, which is subsequently changed and exchanged, suitable connection points are provided. Thus, the reconstruction measures are simplified and made suitable for mass production. Preferably, the rinser also has uniform connection points in the area of the media connections and other structures. In order to allow the fastest possible installation and / or removal of the individual modules, the connection points preferably have a quick-change system, which is preferably a simple clamp system consisting of preferably three clamps, via which the installation and / or removal the modules takes place. As a result, the failure or downtime of the rinser be significantly reduced.

Accordingly, at least in the case of the brackets, the holding devices, the turning stations and the rinsing nozzles, it is particularly preferable to have modules by which the rinser can be widened, changed and / or adjusted and / or which can be arranged at another point of the rinser.

In a further preferred embodiment, the device has at least one control unit and preferably a plurality of control units for monitoring a preform length and / or a nozzle position. These control units may preferably likewise be modules, by means of which the rinser can be extended, changed and / or adapted and / or which can be arranged at a different location of the rinser. However, the control unit may also preferably be an independent device, which is merely associated with the device for cleaning the plastic preforms, but is not connected to it via cutting or connection points. In addition, such a control unit may also be dispensed with a turning station or a turning of the plastic preforms on the cleaning device.

The present invention is therefore also directed to a control unit for a device for cleaning plastic preforms, which has at least one loading device, by means of which an interior of the plastic preforms can be acted upon for their purification with a gaseous medium, wherein the loading device is a nozzle which is stationary or during cleaning with the plastic preforms mitfährt or mitfährt during cleaning with the plastic preforms and immersed in this, wherein the control unit according to the invention prior to the application of the plastic preforms with the gaseous medium, a nozzle position of the nozzle and / or a length of the preforms detected.

In particular, when a change of cloth, it may happen that, for example, a small number of preforms, the previously driven size is still in the device and therefore not compatible with the new nozzles. In the worst case, this can lead to a collision of the nozzle head with the preform. Also, for example, a system error may occur in which the starting time of the nozzle is not set correctly, which also exists the risk of a collision between the nozzle and preform. Therefore, the control unit preferably checks the preform depth and / or the preform length and the start time of the nozzles prior to dipping the nozzles in the preforms to avoid such a collision.

In this case, the control unit preferably transmits a signal to a control device in order to avoid a risk of collision in relation to a large one To enter immersion depth of the nozzles in the preform opening. The control device can then preferentially refuse to start the machine if the nozzle positions are not set correctly and / or drive the machine into the secured emergency stop during an unintentional adjustment during operation.

The position of the nozzles can then preferably be corrected manually manually by an operator or automatically in order to avoid a collision and thus not to disturb the production by a failure of the machine. The preferred combination of monitoring the nozzle position, as well as the preform lengths results in a double hedging, as it may happen that in a grade change, if necessary, a smaller preform remains in the feed line or the device, resulting in a collision between the nozzle and the preform to failure could lead to a treatment unit in the rinser.

Accordingly, the control unit in particular prevents damage to the machine and the resulting loss of production. In addition, a possible collision can be detected early by such a unit, whereby in particular the machine and operating safety is increased. The preferred self-reaction and correction of the program can also be responded to errors as quickly as possible and they can be eliminated as quickly as possible without an operator must intervene manually, so even when the operator is paused or if they are doing other work damage the machine and production losses can be prevented.

In a further preferred embodiment, the control unit is arranged on an inlet star and / or an outlet star. In a further advantageous embodiment, the control unit is selected from a group of control units comprising light barriers, cameras or other suitable sensors.

In this case, further control and monitoring devices are also conceivable. If, for example, ionized compressed air is used to clean the preforms, it would preferably be possible to provide a switchable measuring device which measures the ions in the air stream. By an ionizing gas flow in particular the electrostatic charges are neutralized in the hollow body, whereby dirt particles can be easily solved.

It would also be possible to provide a measuring device or a sensor which controls and / or monitors the compressed air required during the cleaning process in order to detect and remedy a failure of the nozzles and / or the delivery system at an early stage. Preferably, a cleaning control can be provided via a camera, which checks a degree of purification of the preforms after the process run. To avoid a collision between nozzles and preforms, for example, a position control can also take place, whereby preferably a turning process of the preforms carried out with the turning device is controlled by a monitoring unit of the turning angle. Due to a position-accurate turning angle, a higher degree of cleaning can be ensured for certain preform designs.

The device for cleaning plastic preforms preferably has a first discharge device, which is preferably arranged in the inlet of the rinser, so that a recognized with a wrong length preform is ausschleusbar. Preferably, the discharge device is a further transport device, such as a transport star. Furthermore, it is also possible to provide a second discharge device which discharges the preforms identified as being contaminated after cleaning. These preforms are preferably fed again to the rinser and cleaned once more. The inlet and / or the outlet of the rinser is therefore preferably designed such that when a transfer to the rinser or from the rinser a resulting gap between the preforms can be compensated if a faulty preform was discharged. In this way, a desired spacing between the preforms can also be generated relative to one another and in particular matched to a division of the next machine.

Furthermore, it would preferably also be conceivable that a control device is provided for monitoring the preform position in the holding device. In this case, it is preferably checked whether the holding device grips the preform correctly, so that no damage occurs in the further process due to a malposition of the preforms.

It would also be useful to monitor and / or targeted control of the gaseous medium and in particular the compressed air. It would therefore be conceivable, for example, to control the start and end point of the compressed air, depending on the preform embodiment or preform type, whereby the compressed air consumption can be regulated and optimized for each preform by this targeted switching of the injection process. It would also be possible, based on a sensor unit, to check the air flow, which is required for cleaning the preforms, in order to detect deviations of the flow rate and failures of nozzles. The flow of compressed air is preferably based on controlled suitable valves, wherein the cleaning process preferably also to the necessary parameters, which are defined by the desired degree of purification and the preforms to be treated, can be adjusted.

For all monitoring and control units and sensor units described here, an error that has occurred can preferably be corrected manually by an operator or automatically by a control device.

The present invention is also directed to a method of operating a device for cleaning plastic preforms, wherein the plastic preforms are transported along a predetermined transport path with a transport device and a plurality of holding devices for holding the plastic preforms is arranged on a rotatable carousel, wherein the transport device the plastic preforms passes to the holding means of the carousel and an interior of the plastic preforms is acted upon by means of at least one loading device for their purification with a gaseous medium.

According to the invention, the device for cleaning plastic preforms is constructed in modular construction.

It is therefore also proposed on the procedural side to build a cleaning device for plastic preforms as a modular or modular principle to achieve high flexibility in the equipment so that even after the construction of the machine can be responded to the most diverse customer requirements, since the basic structure of the machine can be supplemented, extended and / or changed by individual modules at any time.

In a preferred method, the at least one impinging device is a static nozzle or the at least one impinging device is moved along with the plastic preforms. Compared to a static loading device, an overall better cleaning result can be achieved with a co-moving or moving loading device. Advantageously, the loading device moves with the plastic preforms and is introduced into this. Particularly preferably, the loading device is a rinsing nozzle.

In a further preferred embodiment, at least one turning station is provided, which tilts the plastic preforms by 180 ° and / or rotates about a longitudinal direction. As a result, preferably a complete and in particular complete cleaning of the preforms can be achieved. Particularly preferably, a plurality of such turning stations is provided.

In a further preferred method, at least one control unit is provided, which monitors a preform length and / or a nozzle position, the control unit being arranged on an inlet star and / or an outlet star. Particularly preferably, several control units can also be provided on the method side, which check several and in particular different devices and functions of the rinser for errors, as has already been explained in detail above.

In a further preferred embodiment, the control unit sends a signal to a control device in the case of at least one faulty monitoring result, wherein the control device preferably prevents the device from starting up if the result is erroneous.
