Description

The present invention relates to a cleaning device or a device and a method for cleaning, rinsing and / or disinfecting containers and in particular plastic preforms. Such methods and devices have been known for a long time from the prior art. The plastic preforms are usually heated and then expanded in a heated state to plastic bottles. In many cases, it is necessary to clean the plastic preforms before the heating process and, for example, to rinse. The plastic preforms are isolated from a cleaning device, which is usually a rinser, fed and flushed or blown out with a flowable medium such as a liquid or gaseous medium.

It is known from the prior art that dipping the preforms with the flowable medium for cleaning in the preforms for such a rinsing process, so as to achieve a better cleaning result. This immersion movement or immersion depth of the nozzles is accomplished by a stroke based on a cam. The stroke is particularly constant.

In the case of the cleaning devices known from the prior art, therefore, a cleaning of preforms with different lengths can be carried out only with great difficulty, since no adjustability of the individual nozzle stroke is possible. The cleaning of another preform type, in particular of shorter length, thus leads to a risk of collision between nozzle and preform, which in turn leads to increased costs and reject rates. On the other hand, when cleaning preforms of greater length, complete cleaning of the preform interior may not be guaranteed because the nozzles can not penetrate far enough into the preform. Accordingly, if another type of preform is to be cleaned in the prior art, no ideal cleaning performance can be ensured. No preform change is therefore possible without additional purchase. Rather, it is necessary to replace, for example, the nozzles which dip into the preforms.

The present invention is therefore based on the object to provide a cleaning device and a method with which / with which a cleaning of different plastic preform types and in particular different plastic preform lengths is made possible. 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.

A cleaning device according to the invention for cleaning, rinsing and / or disinfecting containers and in particular plastic preforms has a nozzle device which has a plurality of loading devices, which can be inserted into an opening of the plastic containers for cleaning and a lifting unit, which a lifting element and a particular stationary arranged Having guide curve device. The plunging movement of the loading devices into the plastic containers is furthermore predetermined by a constant stroke movement.

According to the invention, the cleaning device has an adjusting unit, which is arranged such that a height of the nozzle device and / or an immersion depth of the loading devices is adjustable as a function of a length of the plastic containers to be cleaned. A cleaning of the plastic preforms is understood in particular to mean a cleaning of the inner wall or of the inner region of the plastic preforms.

The loading devices are preferably nozzles and, in particular, rinsing nozzles which dip into an opening of the plastic preforms. The nozzle device is preferably a nozzle device, such as a nozzle box, on which the plurality of loading devices is arranged.

It is therefore proposed in this embodiment that an entering into the plastic containers loading device, which may be advantageous to Rinsdüsen, can be set for different preform sizes or lengths quickly and easily in each ideal height. This setting can preferably be done mechanically via, for example, a linear guide or the like, but also electrically.

The cleaning device described can be used both for cleaning plastic preforms and converted containers. Furthermore, the invention will be described herein with reference to plastic containers or preforms, but it will be understood that application to other containers such as glass containers may also be considered.

The cleaning device according to the invention and also the method according to the invention have in particular the advantages that a collision risk can be significantly reduced by such adjustment and in particular can be avoided. Furthermore, with a preform change no additional purchases are necessary. Due to the possibility of an ideal height adjustment of the loading device and in particular of the nozzle tip to the respective preform tip an improved cleaning performance is also ensured.

The containers are preferably transported during cleaning with a transport device along a transport path. For this purpose, the transport device has a plurality of holding devices for holding a respective container. These holding devices are usually known from the prior art brackets for fixing a container. When changing to another type of preform, in particular other diameters, it is necessary to replace these brackets. It is necessary for this purpose in the prior art to remove the brackets individually from the transport device or replace.

By this single replacement of the brackets, however, the time required for replacement, due to the large number of arranged on the transport device brackets is very high and also increases with the number of arranged brackets, which in turn leads to long service life of the machine.

A further object of the invention is therefore to provide a device and a method with which the changeover times for the holding devices for holding the containers can be considerably shortened.

The present invention is therefore also directed to an apparatus for cleaning, rinsing and / or disinfecting containers and in particular plastic preforms, with a transport device which transports the plastic containers to be cleaned along a predetermined transport path, wherein a plurality of holding devices is arranged on the transport device, which each have a changing device, are arranged on the plurality of holding elements for holding the plastic containers. The holding devices are pivotable such that the plastic containers are pivotable about a longitudinal direction by a pivoting of the holding device. Furthermore, the device for cleaning plastic containers is in particular a rinser. The transport path is preferably a circular and / or linear transport path. It would be conceivable also a chain system, which leads the preforms through the oven.

A rinser is understood in particular to mean a cleaning machine which removes dust particles and other residues from the containers by rinsing and / or blowing out containers, the containers being filled with a pressurizing device, which preferably dips into the mouth of the plastic containers, with a flowable medium be charged.

According to the invention, the changing device and the plurality of holding elements can be removed together from the transport device and / or can be arranged on the transport device. Particularly preferably, at least two holding elements are arranged on the changing device, which preferably hold the plastic containers, and which are removable from the transport device together. Advantageously, the at least two retaining elements are arranged on a common changing device, wherein preferably the holding elements with the changing device to which they are arranged, are removable from the transport device.

It would also be conceivable, however, that only the holding elements arranged on the holding device can be removed together from the transport device and the changing device remains on the device. Accordingly, the entirety of the holding device can be understood as meaning both the holding elements arranged on the holding device and the holding elements arranged on the holding device plus additional further elements.

In a preferred embodiment, the changing device is further arranged on a carrier. In a change of the holding elements and the changing device while this carrier remains on the holding device. However, it would also be conceivable that the holding elements, the changing device and the carrier are removed together from the holding device.

The invention therefore proposes that not every retaining element has to be removed individually from the transporting device, but rather a holding / fixing package is provided which is equipped with at least two fixing units or holding elements or also three or more fixing units and is exchangeable.

As a result, in particular, the downtime or downtime of the machine can be significantly shortened, which also saves costs due to the reduced working time Change process can be enabled. In addition, the replacement of a whole holding package is much easier to handle, as the replacement of a plurality of individual holding elements.

It should be noted that the two variants described here can also be combined with one another, ie. the arrangement of a plurality of mutually changeable arranged holding elements and the adjustability of the nozzle devices. In particular, a faster exchange of the respective system can be achieved in this way.

In the above-mentioned changing device may also be advantageous to an exchange robot, which advantageously performs the replacement of the holding devices automatically or semi-automatically. In this case, the holding elements are understood in particular to be those elements which hold the plastic preforms, such as gripping clamps. The holding devices are understood to mean devices which have the holding elements, but also other components, such as changing device, carriers, actuators and the like.

The above-mentioned pivotal movement of the holding device is preferably carried out in a plane which is perpendicular to the transport path of the plastic preforms. The holding device is therefore preferably also a pivoting unit for plastic preforms, which performs a pivotal movement about a predetermined axis and in particular a horizontal axis, in particular in order to guide the plastic preforms with the mouth opening in the bottom direction and thus preferably to be able to remove dirt.

The plastic preforms are advantageously pivoted from a first position in which the mouth projects upwards into a second position in which the mouth projects at least substantially downwards. Preferably, the plastic preforms lie before and after the pivoting with respect to the positions substantially substantially on the same axis. Preference is given to a cleaning and in particular a rinsing or rinsing of the plastic preforms in the said second position, in which the mouth of the plastic preforms protrudes downwards. The pivoting movement itself preferably takes place via guide cams arranged on the transport device. However, it would also be conceivable to control the pivoting via a motor control.

The transport device is preferably a carrier which can be rotated about a predetermined axis of rotation and on which the individual holding devices are arranged. Advantageously, the holding devices are provided on an outer periphery of this rotatable support.

In a preferred embodiment of the cleaning device, the adjusting unit is a mechanically, electrically, manually, pneumatically and / or hydraulically driven adjusting unit. The adjustment can also be done automatically by entering the new preform parameters in a control terminal. Advantageously, a plurality of different preform parameters can already be stored in an operator terminal and selected accordingly.

In a further preferred embodiment of the cleaning device, the nozzle device and / or the loading devices are adjustable in a linear direction and in particular in a vertical direction. Particularly preferably, the nozzle device and / or the loading device are adjustable in a longitudinal direction of the plastic preforms. By adjusting in the direction of the longitudinal direction of the plastic preforms can be achieved in particular a precise adjustment of the depth of immersion of the loading devices in the preforms.

In a further preferred embodiment of the cleaning device, the nozzle device and / or the loading devices are adjustable along a guide rail or a linear guide. Preferably, the guide rail or linear guide is arranged parallel to the longitudinal direction of the plastic preforms. In a further preferred embodiment, the linear guide is arranged on the lifting unit. Particularly preferably, the lifting unit and the nozzle device are therefore arranged on opposite sides of a retaining rail.

In a further preferred embodiment of the cleaning device, the nozzle device can be fixed after the adjustment with a fixing element. By this fixing is thereby prevented that the nozzle device unintentionally adjusted by itself after setting the correct position and, for example, causes a collision of the loading device with the containers or the containers are not sufficiently cleaned. The fixing of the nozzle device takes place for example by jamming via a clamping system. To re-adjustment of the nozzle device, only the clamping device must be solved and the nozzle device can be moved back to any position.

In a further preferred embodiment of the cleaning device, the adjusting unit is a group of adjusting units selected, which includes a clampable carriage, a toothed belt system, a linear spindle table, a rack, a guided in a groove screw connection, a connector, a clamp connection and the like. As already mentioned above, the adjustment of the adjusting unit can be effected mechanically, electrically, manually, pneumatically and / or hydraulically or also automatically.

In the height adjustment of the nozzle device via a clampable carriage, the carriage is pressed by tension on an associated rail or the like, and thus prevented from slipping or held. By releasing the voltage of the carriage and thus also arranged on this slide nozzle device is free to move and can be adjusted accordingly. The detailed description of the adjustment of the nozzle device via the carriage will be made with reference to the figures and in particular 3 explained in more detail.

In a height adjustment by, for example, a toothed belt system or a rack, the nozzle device is locked in the desired height. Also a groove-guided screw or a detachable connector, or similar systems can be used for height adjustment. Likewise, it is conceivable to adjust the individual nozzles automatically, for example via a carousel rotation. The detailed description of the adjustment of the nozzle device will be made with reference to the figures, and in particular Figs 4-7 explained in more detail.

In a preferred embodiment of a device for cleaning containers, the holding elements are holding clips which hold the plastic containers at a neck area and, in particular, engage. Particularly preferably, these retaining clips hold the plastic containers above a support ring. As mentioned above, the holding device is pivotable in such a way that the plastic containers are pivoted about a longitudinal direction. In the mentioned holding device is therefore preferably also a pivoting device for pivoting the containers.

In a further advantageous embodiment, the pivoting device has an actuator, which is movable for pivoting the holding device or the pivoting device. It is conceivable, for example, that this actuator is linearly movable, in particular by using a guide curve.

In a further preferred embodiment, at least two and more preferably at least three holding elements are arranged on the changing device. Accordingly, preferably at least two and more preferably at least three retaining clips are exchangeable together or removable from the device. Particularly preferably, any number of retaining elements may be arranged on the changing device, which are exchangeable together. The changing device fixes the brackets preferably at a predetermined distance from each other.

The holding elements, which are preferably designed as clamps or similar holding systems, are used in container treatment machines, preferably cleaning systems and in particular in concentric rinses for preforms. The holding device, which is preferably designed with three retaining clips, can be attached to the treatment unit with the aid of a changing system.

In a further advantageous embodiment, therefore, at least one holding device for holding at least two containers is suitable and determined. At least one holding device is preferably suitable and intended for holding at least three containers. It is advantageous at least one holding device for holding between two and ten containers, preferably from between two and eight containers, preferably from between two and six containers, preferably from between two and five containers and more preferably from three to five containers, and more preferably from exactly three containers suitable. In this case, these containers are preferably pivoted together. Accordingly, between two and eight, preferably between two and six, preferably between two and five and particularly preferably between three and five retaining clips are particularly preferably arranged on the holding device, which are particularly preferably jointly exchangeable.

By arranging a plurality of holding elements on a holding device or a changing device, it is also possible to minimize the drive units. In addition, a faster format change is possible because the retaining elements can not be changed individually but in terms of packet. In addition, the number of wear parts is reduced by reducing the pivot units.

In a further preferred embodiment, the holding elements are active, that is, can be opened and closed to hold or release plastic containers. In this case, this opening and closing of the holding elements preferably takes place via a drive device. This drive device particularly preferably has a guide curve and / or guide rollers. It would also be conceivable, however, beyond electric, pneumatic, hydraulic drive or the like.

In a further advantageous embodiment, the changing device is mechanically, electrically, pneumatically, hydraulically, magnetically, manually or similarly activated. Particularly preferred for this purpose each holding device is assigned a drive device.

In a further preferred embodiment, the changing device on a quick-change system, which allows a quick changeover to other holding elements. The quick-change system preferably includes a movable connection part, which allows the opening and closing of the exchange mechanism and which is preferably arranged on the transport device. The connection part is preferably mechanically, electrically, pneumatically, hydraulically, magnetically or manually operable. A counterpart to this connection part is preferably integrated in the holding device and preferably makes it possible to fix the holding device to the transport device. The quick-change system or the changing device is preferably designed such that it is easily accessible and operable. The quick-change system advantageously allows, in particular, short changeover times of the holding elements and rapid conversion to the new preforms.

It is possible that the entire pivoting device or holding device is modularly removable from the transport device. It would also be possible and preferred that only one module containing the individual holding elements, i. the changing device and the holding elements arranged thereon, but not the drive, which causes the pivoting movement, is changed.

In a further preferred embodiment, the plastic containers on the holding device have a constant distance from each other, so that a simple cleaning of the plastic containers can be made and the loading devices do not interfere with each other during cleaning. Furthermore, this can also be prevented that the loading device damaged during retraction and extension from the plastic container adjacent containers.

In a further preferred embodiment, the device for cleaning the plastic containers is preferably arranged upstream of a forming device for forming plastic preforms into plastic containers. A cleaning of the plastic preforms is therefore carried out immediately before forming.

The present invention is therefore also directed to a system for treating containers and in particular plastic containers, which has at least a first and a second treatment device, wherein the plastic containers are transportable from the first treatment device to the second treatment device. According to the invention, the first treatment device is the device according to the invention for cleaning plastic containers and the second treatment device is a forming device for converting plastic preforms into plastic containers.

In a further preferred embodiment, the device has a loading device, which acts on an interior of the plastic containers with a flowable medium and in particular a gaseous or liquid medium. The loading devices are preferably nozzles and, in particular, rinsing nozzles which dip into an opening of the plastic preforms. By means of a gaseous medium, for example compressed air, the plastic preforms can be advantageously blown out and with a liquid medium, the preforms could be rinsed.

In addition or in addition, however, a sterilization of the plastic preforms would be conceivable, for example, an application of a gaseous or liquid sterilant. In addition, combinations of these approaches are conceivable. Thus, for example, an initial blowing out of the plastic preform with air and then an admission with a gaseous or liquid sterilizing agent. Preferably, this loading device is oriented such that it directs a flow of the loading means in the direction of the plastic preforms.

The present invention is further directed to a method for cleaning, rinsing and / or disinfecting containers and in particular plastic preforms, comprising a nozzle device having a plurality of loading devices, which are inserted for cleaning the plastic containers in an orifice of the plastic containers and with a lifting unit , Which has a lifting element and a guide cam device arranged in a stationary manner, and the plunging movement of the loading devices into the plastic containers is predetermined by a constant lifting movement.

According to the invention, a height of the nozzle device and / or an immersion depth of the loading devices are dependent on a Adjusted length of plastic containers to be cleaned.

Accordingly, it is also proposed on the method side to provide a loading device which can be adjusted quickly and easily in the respectively ideal height for different preform sizes or lengths.

In a preferred method, the nozzle device and / or the loading devices are adjusted in a linear direction and in particular in a vertical direction. An adjustment in a linear and in particular a vertical direction is preferably understood in general to mean, in particular, an adjustment in the longitudinal direction of the plastic preforms.

In a further preferred method, the nozzle device is fixed after the adjustment with a fixing element in order to prevent an unwanted adjustment or release of the nozzle device from the set position.

The present invention is also directed to a method for cleaning, rinsing and / or disinfecting containers and in particular plastic preforms, comprising a transport device which transports the plastic containers to be cleaned along a predetermined transport path, wherein a plurality of holding devices is arranged on the transport device, which each have a changing device, are arranged on the plurality of holding elements for holding the plastic containers, wherein the holding devices are pivoted such that by pivoting the holding device, the plastic containers are pivoted about a longitudinal direction.

According to the invention, the changing device and the holding elements are removed together from the transport device and / or arranged on the transport device. In such a method, it is proposed not to remove each holding element individually from the transport device, but rather to provide a holding / Fixierpaket, which is equipped with at least two fixing units or holding elements or three or more fixing units, which are exchangeable together.

In a preferred method, the changing device is arranged on a carrier. This carrier preferably remains in a replacement of the holding elements on the holding device. However, it would also be conceivable that the changing device, the holding elements and the carrier are removed together from the holding device and / or arranged on the holding device.

In a further preferred method hold and in particular the holding elements grip the plastic containers at a neck area and preferably above a support ring of the containers.

The inventions described here or the inventive aspects described here are each based on the common concept of enabling a cleaning of plastic containers in a particularly simple and efficient manner, in particular preventing damage and downtimes of the system or considerably shortening them.
