Definitions

  • Forming machine for forming preforms into containers and operating method thereof
  • the present invention relates to a forming machine for forming preforms into containers by introducing a forming fluid under pressure into the preforms.
  • the present invention relates to a method for operating a forming machine for forming preforms into containers by introducing a forming fluid under pressure into the preforms.
  • a blow molding machine has a heating device for tempering or thermally conditioning the preforms and a blowing device with at least one blowing station, in the area of which the previously temperature-conditioned preform is expanded into a container.
  • the expansion takes place with the help of a compressed gas (compressed air) as a pressure medium, which is introduced into the preform to be expanded using a molding pressure.
  • a compressed gas compressed air
  • tempering the preforms DE 23 52 926 A1 explains.
  • Tempering or thermal conditioning means that the preform is heated to a temperature suitable for blow forming and, if necessary, a temperature profile is impressed on the preform.
  • the blow molding of containers from preforms with the additional use of a stretch rod is also known.
  • the containers produced by blow molding are fed to a subsequent filling device and filled here with the intended product or filling material. So a separate blow molding machine and a separate filling machine are used. It is also known to form the separate blow molding machine and the separate filling machine into one machine block, i.e. H. to form an interlocked blow-filling device, with the blow-molding and filling continuing to take place on separate machine components and one after the other.
  • each of the forming stations has a mold receptacle which holds a detachably attached, multi-part outer mold, against the inner contour of which the preforms are expanded.
  • the inner contour of the outer mold thus determines the contour of the expanded preform.
  • a heated preform is fed into the outer mold of the forming station.
  • the preform is then formed into a container by introducing a forming fluid under pressure into the preforms.
  • the preform expands in the outer mold and presses against the outer mold.
  • the inner contour of the outer shape therefore determines the shape of the containers produced.
  • This conversion of the molding machine can take a relatively long time, for example a few hours, due to the large number of forming stations.
  • the time required to change over the forming machine is also called changeover time or changeover time. Since modern forming machines are designed to produce several thousand containers per hour, such long downtimes or changeover times are generally undesirable. It is desirable to keep downtime or changeover times as short as possible.
  • the forming machine and in particular the forming stations have, for example, hydraulically pivotable components, which pose a risk of jamming or shearing for the machine operator (m, w, d) during changeover if a manual mold change is carried out.
  • the outer shape is a solid metal block that can tip or fall down when changing. This can either damage the mold holder or parts of the forming station or, in the worst case, personal injury can occur if the external mold comes loose in the mold holder in an uncontrolled manner.
  • the object of the present invention is therefore to address one of the above-mentioned problems, to improve the general state of the art or to provide an alternative to what was previously known.
  • a solution is to be provided with which the changeover time of the forming machine can be reduced and at the same time the forming machine can be changed over safely.
  • the forming machine is set up for forming preforms into containers by introducing a forming fluid under pressure into the preforms.
  • the forming machine can, for example, be designed as is generally known from the prior art, for example as a blow molding machine in which the preforms are formed with a gas or directly with a filling material.
  • the forming machine is therefore set up to form the preforms into a container.
  • the forming takes place with a forming fluid.
  • a forming fluid is a fluid that is used to form the preform, for example a gas or filling material, as is known in the prior art, for example. This fluid is introduced into the preform under pressure to expand the preform.
  • a forming machine is therefore understood to be a machine in which the forming and filling of the produced containers takes place simultaneously in one production step, also called hydraulic forming, or a machine in which the forming and filling of the produced containers takes place in two separate production steps, i.e. e.g. B. a blow molding machine with a downstream filling machine.
  • the preforms are also known as preforms or PET blanks.
  • the preforms can be formed from different thermoplastic materials, such as polyethylene terephthalate (PET), polyethylene (PE), polyethylene naphthalate (PEN) or polypropylene (PP) or the like.
  • the preforms have, for example, a closure thread and a mouth section.
  • the containers into which the preforms are formed are, for example, bottles, canisters or the like.
  • the forming machine has a rotationally driven forming wheel, i.e. a forming wheel that can be set in rotation with a drive device.
  • the drive device is, for example, a controllable electric motor that is controlled by a control device of the forming machine. It goes without saying that the forming wheel is rotatably mounted for this purpose.
  • each forming station has a mold receptacle which holds a detachably attached, multi-part outer mold against the inner contour of which the preforms are expanded.
  • the mold holder thus forms a holder and holder for the external shape. It is therefore proposed that one preform is introduced into a multi-part outer mold of a molding station and expanded therein.
  • the preform By introducing the forming fluid under pressure, the preform expands in the outer mold and presses against the inner contour of the outer mold, which is accommodated in the mold holder. It is understood that the outer mold is closed when the preform is expanded and the outer mold is opened when the preform is automatically inserted into the outer mold in a transfer area.
  • the mold holder is opened and closed in the transfer area, i.e. the area on the forming wheel where the preforms are introduced into the forming stations, for example by means of a cam control, for example cam rollers coupled to the forming station run along an external control cam.
  • the outer shape is, for example, an aluminum shape that is made up of three parts, namely two side shells and a base part.
  • the external shape can also be referred to as a multi-part mold.
  • the side shell is also synonymously referred to as a side part.
  • the bottom part is also synonymously referred to as the bottom shape.
  • the outer shape is releasably fastened in the mold receptacle and is fastened in the mold receptacle for example with a fixing means and/or a holding means.
  • the fixing means is a zero tension system and the holding means is a bar gripper.
  • the mold holder has a controllable fixing means for holding the external mold.
  • the fixing means is therefore a means that is provided for fixing the outer shape in the mold holder of the forming station.
  • the fixing means is designed to be controllable and can be moved into a fixing position and into a by means of control Release position can be brought.
  • the control device therefore controls the fixing means in such a way that the release position or the fixing position are set.
  • the fixing position is a position of the fixing means in which the outer shape is fixed in the mold holder by the fixing means.
  • the fixing position can also be understood as a locked or unlocked position. In the fixing position, the outer form cannot be separated from the form holder.
  • the release position is a position of the fixing means in which the outer form is no longer held fixed in the mold holder by the fixing means.
  • the release position can also be understood as an unlocked or released position. In the release position, the outer mold can be separated from the mold holder.
  • a pneumatically, hydraulically, electrically and/or mechanically driven fixing means can be provided as a controllable fixing means.
  • the fixing means is a zero tension system.
  • the forming machine has a detection means for detecting a rotational position of the forming wheel.
  • the detection means is therefore a means that detects the rotational position of the forming wheel using sensors.
  • the detection means can also be understood as a position sensor and is, for example, a rotary encoder or a rotary encoder device.
  • preforms are fed to the forming machine in a transfer area.
  • the preforms are fed, for example, with a transfer wheel that receives thermally preconditioned preforms from a heating device.
  • the transfer area The area where the preforms are introduced or removed into the forming station or into the external mold during normal operation is referred to as the transfer area. Normal operation is also known as production mode.
  • the forming machine also has a control device which controls the operation of the forming machine and to which the detection means is connected.
  • the control device is designed, for example, with a bus system and a master control and additionally or alternatively has control devices to control a heating device, to control a drive device of the forming wheel, to control safety components of the forming wheel, or in order to To control components of the forming wheel or the like.
  • This control device can also be referred to synonymously as an electronic control device.
  • the control device controls the forming machine in a first operating mode, a production mode, for the production of containers from preforms.
  • the control device is therefore set up to control the forming machine or its controllable components in the production mode.
  • the production mode can also be understood as standard operation, normal operation, production operation or ongoing operation.
  • the molding machine is set up to produce the containers and containers are produced with the forming machine and output to an output line.
  • the electronic control device also controls the forming machine in a second operating mode that is different from the first operating mode, a conversion mode, for changing the multi-part outer shape for another multi-part shape.
  • the control device is also set up to control the forming machine or its controllable components in the conversion mode.
  • the conversion mode can also be understood as service operation, conversion operation or interrupted operation.
  • the conversion mode the forming machine is converted to produce the containers and no containers are produced with the forming machine and output to an output line.
  • the multi-part external shape is changed to another multi-part shape.
  • the control device is designed to control the fixing means of a forming station into the release position when this forming station reaches a predetermined first position relative to the transfer area, and/or to control the fixing means of the same forming station into the fixing position when this forming station has a predetermined second position relative to the transfer area is reached. It is therefore proposed that the electronic control device unlock the fixing means that holds the outer mold in the mold receptacle when the forming station reaches the first position and/or lock the fixing means when the forming station has reached the second position.
  • the first and second positions can also be understood as rotation angle positions. For example, if the transfer area is set to 0° as a reference point, the first position can be set as 250° and the second rotation position as 290°.
  • the control device controls the fixing means so that the release position of the fixing means is set. If the same forming station then reaches the second position, the control device controls the fixing means so that the fixing position of the fixing means is set. Since the forming stations are arranged around the circumference of the forming wheel, the individual positions of the forming stations on the forming wheel are known. For example, if 16 forming stations are arranged on the forming wheel, the forming stations can be arranged circumferentially distributed on the forming wheel in 24 degree increments. Since the local position of the forming stations is known, the current location of each forming station can be deduced from the detected rotational angle position of the forming wheel.
  • the first and second positions can thus be stored in the control device as threshold values for the rotational position of the forming wheel in order to automatically control the fixing means.
  • a lock-up table or a program code can be stored in the control, which, when the forming wheel reaches a predetermined rotational position, controls a predetermined forming station and controls its fixing means.
  • the control device is therefore set up to automatically control the fixing means of the mold holders of the forming stations.
  • the first position and the second position define a release area which extends in the circumferential direction of the forming wheel from the first position to the second position, with the fixing means being in the release position in the release area.
  • a predetermined local area is therefore proposed, which exists between the first position and the second position. In this local area, the fixing agents that hold the outer mold in the mold holder are loosened and released.
  • the release area can also be understood as a fixed angular area.
  • the fixing means are located outside the release area in the fixing position. It is therefore proposed that the fixing means are only loosened within the release area and are tightened outside the release area.
  • the release area is preferably an area that lies outside the transfer area. It is therefore proposed that the transfer area and the release area are geographically different.
  • the release area can, for example, be arranged next to the transfer area or opposite the transfer area.
