Description

The present invention relates to a device for forming plastic preforms into plastic containers, wherein the device has a collecting station, which receives ejected plastic preforms or discharged plastic containers.

Such devices for forming plastic preforms into plastic containers have long been known from the prior art. It is also known to switch such devices, for example, to a heating device, so that the plastic preforms are received in a heated state of the device for forming, wherein plastic preforms or finished blown plastic containers, which may be damaged, can be discarded.

In the applicant's internal state of the art, damaged plastic preforms and plastic containers are discharged in a stretch blow molding machine at the inlet or outlet star via an ejection device into a receiving device. In the internal state of the art of the Applicant this receiving device is divided into two areas, namely one area for the plastic preforms and another area for the plastic containers. The ejected plastic preforms or plastic containers usually fall into boxes where they are collected. In most cases, such a receiving device is equipped with rollers, whereby it is possible to drive the receiving device with the machine housing open from the machine, whereby access to the machine elements arranged behind it is made possible. During ongoing operation of the stretch blow molding machine, it is possible to remove the boxes which receive the discharged plastic preforms or plastic containers via cutouts in the doors of the machine housing. Thus, it is possible to empty the receiving device without having to interrupt the operation of the forming device. However, such prior art devices known to the Applicant have some disadvantages. For example, some adjustments are necessary to properly position the pick-up in height and the necessary circuit breakers. It is also difficult to push the receiving device into the machine, since a connection to the circuit breaker has to be established by pushing it in. The present invention is therefore based on the object to overcome the known from the prior art disadvantages and to provide an apparatus for forming plastic preforms to plastic containers available in the ejected plastic preforms and / or plastic containers are included in a novel catcher, said Not only catcher can be easily attached to the device, but also adheres to all safety issues and intervention or getting into the machine during a operation is also theoretically no longer possible, with emptying of the collection containers during ongoing operation is still possible.

These objects are achieved by the subject matter of the independent claims. Advantageous embodiments and further developments are the subject of the dependent claims.

An inventive device for forming plastic preforms into plastic containers has a transport device which transports the plastic preforms along a predetermined transport path. In this case, this transport device has a movable carrier on which a plurality of forming stations is arranged. These conversion stations are each suitable and determined to reshape the plastic preforms to the plastic containers. In addition, the device has a feed device, which supplies the device, the plastic preforms and a discharge device, which discharges the plastic containers from the device. Furthermore, a discharge device is arranged on the device, which in particular discharges selected plastic preforms or selected plastic containers out of the transport stream, in particular during a running operation. In particular, the selected containers may be damaged containers

Preferably, the selected plastic preforms or selected plastic containers are such plastic preforms or plastic containers which have recognizable quality defects. However, it would be quite conceivable that plastic preforms or plastic containers are discharged due to other conditions, these conditions can be determined or determined for example by an operator of the device. For example, a test run of the feed would be conceivable, with all plastic preforms being discharged here.

The device for forming plastic preforms into plastic containers is preferably a blow molding machine. This means that the plastic preforms initially thermally conditioned in a heating section and then by applying a liquid or gaseous medium to be expanded. The flowable medium is preferably under pressure. For the supply of the pressurized medium, the device has a blowing nozzle, which is sealingly engageable with an orifice of the plastic preforms to expand the plastic preforms so with liquid or gaseous medium. In addition, a valve arrangement is preferably provided which controls the supply of the blowing air to the plastic preforms.

The blow molding devices are preferably transported within the clean room. The clean room is preferably limited by several walls. In this case, the clean room is preferably delimited by at least one stationary wall and a wall which moves relative to this wall. The clean room delimits the blow molds in particular from an unsterile environment. Advantageously, the clean room is annular or toroidal formed around the blowing stations or forming stations and / or the transport path of the plastic containers. An expansion of the plastic preforms with a liquid would also be conceivable.

According to the invention, the device has a collecting station for ejected plastic preforms and for discharged plastic containers.

The collecting station is preferably arranged below the feed device and the discharge device. Under below is to be understood that the collecting stations has a lower level so the feeder, discharge device and / or as the transformation stations. Thus, the catching station has a lower level than the transport path. In other words, the reception station is closer to the ground than the transport path. Particularly preferably, the collecting station is arranged below and between the feed device and the discharge device. Thus, the catchment station is positioned so that it can accommodate both the ejected plastic preforms and the discharged plastic containers. The feed device is preferably designed as an infeed star and the discharge device preferably as a discharge star. However, other embodiments of the supply and the discharge devices would be conceivable.

The collecting station preferably has a first container catching device and a second container catching device. Preferably, the first container receiving device is assigned or assigned a first opening. Preferably, the second container receiving device is assigned to a second opening. In a preferred embodiment, both the first and the second container catcher each have a collecting container. These collecting containers are preferably arranged within the container receiving devices. The collecting containers can be removed from the container receiving devices via the respective openings. These collecting containers can preferably be removed during ongoing operation of the device without this having to interrupt its operation.

Preferably, several variants are conceivable, such as the collecting containers are arranged within the collecting station. It would be conceivable that the collecting containers are set in the sanctuary. It would also be conceivable that the collecting containers are hung in the rescue station. Both in the variant of setting and the hanging, the collection containers are in a lower area of the rescue station. In this case, the lower area is preferably the area that is meant for the floor on which the entire device is built closer is. In addition, it would also be conceivable that the collection containers are parked directly on the floor within the catcher.

In a preferred embodiment, the collecting containers are formed as a cuboid, so to speak as a kind of box. However, other shapes such as a cube shape are not excluded. In addition, other forms are conceivable. Preferably, the plastic preforms and plastic containers, which were discharged from a discharge device from the actual transport stream, fall into this collecting container. In a preferred embodiment, in particular selected plastic preforms or selected plastic containers are recognized by the discharge device. For this purpose, the device preferably has at least one identification device. In this case, it would be possible for the device to have a recognition device which is suitable and intended to recognize selected plastic preforms and has a further recognition device which is suitable and intended to recognize selected plastic containers. By this is to be understood that a detection device is suitable and intended to recognize plastic preforms or plastic containers, which are to be selected, that is, for example, which have recognizable quality defects. It should be noted that a detection device also plastic preforms or plastic containers also selects on the basis of other requirements, which are for example given by an operator and, for example, differ from a quality defect. The detection can preferably be accomplished via one or more sensor devices. The discharge of the plastic preforms or the plastic containers is preferably carried out during operation of the device and the ejected plastic preforms or plastic containers fall into the collecting station. For this purpose, the collecting station is preferably formed in two parts and can thus be divided into two areas. A first area is assigned to the ejected plastic preforms, a second area is assigned to the discharged plastic containers.

In a preferred embodiment, the catching station has at least one safety device which prevents entry or intervention in the device during operation. Preferably, the at least one safety device is designed such that entry into or intervention in the device during a production process (also theoretically) is no longer possible.

Preferably, a machine housing is present on the device. Particularly preferably, the entire device is surrounded by a machine housing. Thus, preferably both the transport devices such as, feeder, discharge device, rotatable support, etc., and the forming device are within the machine housing. In a preferred embodiment, doors are arranged on the machine housing in the region of the supply and discharge device, which can be opened when the machine is at a standstill. Preferably, the device has a safety device which is suitable and intended to prevent opening of the doors during a production process, that is, in particular has means that actively hold the doors. This active locking of the doors means that no door can be opened during a production process. At a standstill of the device, the doors can be opened, whereby, for example, a machine operator can get into the interior of the device to perform, for example, maintenance.

In a preferred embodiment, the catching station is arranged on the doors of the machine housing. Preferably, both the doors of the machine housing and the receiving station are designed such that in a closed position of the doors, the collecting stations is at least partially disposed below the supply and discharge device. Particularly preferably, the first container catcher is at least partially disposed below the feeder and the second container catcher is at least partially disposed below the discharge means.

Preferably, the door on which the container collecting device is arranged, which is assigned to the plastic preforms, in the lower region, that is, in the region in which the collecting container is a recess, so that the collecting container of the container catcher can be removed. Preferably, the door on which the container collecting device is arranged, which is associated with the plastic containers, in the lower region, that is in the region in which the collecting container is a sliding gate, which can be pushed up during a production process, whereby the collecting container removed can be. Advantageously, the doors each have a viewing window. Thus, for example, can be seen through the window in the respective collection container and checked to see if a collection container must be emptied or not.

Advantageously, the two sides of the collecting station have different safety devices (in the process, different concepts), which prevent entry or intervention in the device during operation. More specifically, the first container catcher has a different safety device than the second container catcher. Thus, the container receiving device which is assigned to the plastic preforms has a different safety device than the container receiving device which is assigned to the plastic containers.

In a preferred embodiment, a plurality of transverse struts are disposed above the collecting receptacle of the receptacle receiving device, which is assigned to the plastic preforms. The individual cross struts have such a distance from one another that a step into the device during a production process is theoretically no longer possible. However, the distance between the individual transverse struts is large enough that the ejected plastic preforms can fall through. The cross struts can be made for example of metal or plastic. Preferably, the transverse struts are mounted rotatably mounted on a side wall of the container catcher and can preferably be pivoted downwards, so that access to the device is made possible at their stoppage. However, it would also be conceivable that the cross struts are not laterally but for example arranged on the front side of the container catcher and can be pivoted upwards. In addition, other embodiments are conceivable.

The rear area of the container catching device, that is to say the area opposite the door of the machine housing, is preferably designed such that it remains on the device, preferably as well as part of the guide plates which catch the discharged plastic preforms and pass them on to the collecting receptacle. Another part of the baffles for collecting and forwarding the plastic preforms acts preferably at the same time as a side wall of the container catcher and is advantageously attached to this.

Preferably, the plates remaining on the machine are arranged in such a way that they can be removed from the device without tools, which enables particularly easy access to the device when it is at a standstill. In addition, however, it would also be conceivable that all elements of the container catcher are arranged on the machine door.

Preferably, the door can only be closed and thus the device can be put into operation when the cross struts are in the, according to the embodiment in which the cross braces are arranged laterally, the upper position in the. Advantageously, only fits such a locking device such as a cam or a bolt in a designated cutout. Due to this safety device can be ensured that the struts are always up or in a closed position during operation of the device and thus the safety device is active. During a production process, the struts are held in the upper or lower position via a latching function.

In a further embodiment, the container receiving device has a deflecting plate. This deflector can preferably be suspended in the container catcher and is preferably used to divert the discharged plastic preforms, for example, ausschleiten from the blow molding machine. By such a deflector, a commissioning time of a blow molding machine can preferably be shortened, since the plastic preforms are led directly to the outside. As a result, a longer continuous test run of the supply of the plastic preforms is possible without causing plastic containers to be blown. Therefore, it may be preferred to set up a supply of the plastic preforms, wherein subsequent machines of the blow molding machine are not yet in operation. In this operating state, the safety distances against intervention and / or full body access are preferably also given.

Advantageously, another safety device is used in the other container catcher. As already mentioned above, the machine door on which the container receiving device, which is assigned to the plastic containers, has a sliding gate in the region of the collecting container. On the inside of the sliding gate is preferably a guide element and in particular a sheet metal bracket attached. The container receiving device, which is assigned to the plastic containers, is preferably mounted on the machine door and advantageously runs obliquely in the direction of the door.

Due to this geometric shape creates a bottleneck above the collecting container. Preferably, the bottleneck is opened wide enough in a closed position of the sliding gate, that even a large number of discharged plastic containers that fall at short intervals in succession in the container catcher can be forwarded into the collection container.

In a preferred embodiment, the sheet metal angle is mounted on the inside of the sliding gate, that when this is opened to a collecting container of the container catcher to Also, the metal bracket on the inside with high is performed. Preferably, the bottleneck is reduced to such a degree by the change in position of the inner sheet metal angle that an intervention or boarding in the device is also theoretically no longer possible.

Preferably, the sliding gate is locked by a latching function at different positions. In a preferred embodiment, these locking functions must be operated from the outside, thus, a bypass of the safety device can be prevented.

In a preferred embodiment, the entire container catcher swings when the machine door is open when the device is at a standstill. Preferably, this Mitausschwenken allows access to the stationary device. This access is achieved in a particularly simple manner, since only one door must be opened and no other facilities or panels must be dismantled.

The present invention further relates to a collecting station for collecting discharged plastic preforms and / or plastic containers. The collecting station preferably has a first container catching device and a second container catching device. These container receiving devices are advantageously arranged next to one another, wherein the first container catching device has a first opening and the second container catching device has a second opening. Preferably, a collecting container, which is located within the container receiving devices, can be removed via these openings.

The container receiving devices preferably have different safety devices which are suitable and intended to prevent intervention or entry into a machine during ongoing operation.

Advantageously, the respective safety devices are designed in such a way that they also theoretically no longer make it possible to intervene or get into the machine. In a preferred embodiment, the catching station is arranged on the doors of the machine housing. Preferably, both the doors of the machine housing and the receiving station are designed such that in a closed position of the doors, the collecting stations is at least partially disposed below the supply and discharge device. Particularly preferably, the first container catcher are at least partially below the feeder and the second container catcher at least partially disposed below the discharge device.

In a preferred embodiment, the container receiving devices have a retractable or adjustable collecting container. This collecting container can be parked for example on a bottom of the container catcher or on the ground. In the latter case, the container catcher is bottomless. It would also be conceivable that the collecting container is hung in the container catcher. In a further embodiment, it would be conceivable that the collecting containers are pushed or pulled over a rail construction in the container catcher.

Preferably, the sliding gate is locked by a latching function at different positions. In a preferred embodiment, these locking functions must be operated from the outside. In a preferred embodiment, the entire container catcher swings when the machine door is open when the machine is at a standstill. Preferably, this Mitausschwenken allows access to the stationary machine.

The exact configuration of the collecting device has already been described in detail above.

The present invention further relates to a method for forming plastic preforms into plastic containers with a transport device, with which the plastic preforms are transported along a predetermined transport path. Preferably, the transport device in this case has a movable carrier, on which a plurality of forming stations are arranged. These conversion stations are suitable and determined to transform the plastic preforms to plastic containers. For this purpose, the plastic preforms are fed via a feed device and the plastic containers are removed via a discharge device. In particular, selected plastic preforms or selected plastic containers are preferably removed by means of a discharge device from the transport stream during a running operation.

The discharged plastic preforms and the plastic containers are preferably received by a collecting station.

The present invention offers several advantages over Applicants' internal prior art. A removal of the collecting container and access to the inside of the machine can be achieved by simply swinging the machine doors. An exact setting of The height and position of the safety switch is no longer necessary because the height is already determined by a screwing on the door and a safety switch is eliminated. In addition, the device according to the invention provides protection against boarding or intervention in a running machine. Furthermore, it is possible by means of a device according to the invention to shorten the start-up times of, for example, a blow molding machine, since, for example, a further device can be suspended, whereby the plastic preforms are guided directly to the outside. This allows a longer continuous test run the supply of plastic preforms, without causing plastic containers are blown. Thus, the setting of the supply can already be done when the successor of the blow molding machine are not yet in operation, which are given in this operating state of the machine, the safety distances against intervention and full body access.
