Definitions

  • the invention relates to a method for transporting in particular light objects, in particular empty or full PET bottles, and a device therefor.
  • the present invention relates to all objects, in particular those having an opening, of whatever kind, and a neck ring, of whatever configuration. It mainly refers to PET containers.
  • the PET industry is a high technology manufacturing area of the packaging industry and is experiencing tremendous growth as the benefits of PET containers are evident.
  • PET bottles in all shapes, sizes and colors.
  • preforms are produced for this purpose, which are then optionally supplied by cooling and / or heating sections of a stretch blow molding machine. In this stretch blow molding machine, the preforms are then given the shape of the PET bottle.
  • this PET bottle must be transported on for labeling, filling and sealing and for packaging or palletizing.
  • the transport of empty bottles takes place predominantly by means of air flow.
  • the bottles are placed with the neck ring on slides and transported with the help of accelerated air.
  • This process is very energy intensive and causes high operating costs.
  • a large consumption of filtered air is necessary.
  • Another disadvantage is the flexibility of the system, since the change from one bottle type to another (format change due to different head diameter) can only be completed with a great deal of time or automation effort. Often, for this reason, two parallel transport routes must be installed several hundred meters long.
  • the objects namely PET bottles are gripped by a gripping device on her neck and transported in most horizontal position.
  • the gripping devices are located on a chain consisting of firmly connected members. Enormous forces act on the system, which is also subject to great wear. The speed of the system is limited, there is no storage space.
  • Object of the present invention is to substantially simplify the transport of empty and full objects with an opening and a neck ring, in particular the transport of PET bottles, cheaper, traceable and secure design and to develop a device with which a handling of to be transported objects is made very flexible.
  • a two-part gripping device wherein a gripper, namely the inner gripper, lowers at the bottle transfer into the bottle opening, while a second gripper, namely the outer gripper, from below attacks below the neck ring the object and thus the article after closing the gripping device is secured against vertical slipping.
  • the gripper vehicle is constructed substantially soupschklig as a pair of scissors.
  • Both gripping arms are connected to each other in a scissor-like manner via an axis of rotation, wherein a closing spring fastened to a gripping arm can still optionally be provided, which supports the object against the other
  • Transport lock ensures that the gripping device does not open.
  • the object to be transported is kept secure. Furthermore, the
  • Object in any position in space, d. H. can also be transported horizontally or overhead. This means considerable flexibility in guiding the article from one processing station to another.
  • both gripping arms are substantially designed as leg-like flat pieces, so that the one gripping arm which forms the entire rear wall of the gripper vehicle can also be referred to as a base leg and the other gripping arm as a scissor leg.
  • the outer gripper is located on the base leg and the inner gripper on Scissor legs.
  • an externally actuable gripper can be arranged on a rigid gripper vehicle.
  • a special focus of the invention is dedicated to the automation of taking over the objects.
  • elements on the gripper vehicle interact with the rail.
  • the rail preferably consists of a simple, flat strip of material having a certain height. If this height is changed, then it should come to an opening movement of the two gripping arms. In a preferred embodiment of the invention, this is done by three rollers are arranged on the gripper vehicle.
  • a roller which runs off the upper edge of the rail, essentially sits on the axis of rotation of the base leg and scissor leg.
  • Another roller, which is connected to the base leg runs off a lower edge of the rail, a third roller, which also runs off the lower edge of the rail, is connected to the scissor leg.
  • the axes of rotation of the three rollers form a triangle with each other.
  • the gripper vehicle should still be assigned a transport safety device, ie, a safety device that ensures that the gripping arms do not allow any unwanted opening movement during normal transport of the object.
  • a transport safety device ie, a safety device that ensures that the gripping arms do not allow any unwanted opening movement during normal transport of the object.
  • the above-mentioned closing spring already ensures very well that the objects are held between the grippers. However, accelerations caused by speed changes or centrifugal forces, it is especially for long items, such as PET bottles, possible that the gripping device can open, that is, that the force of the closing spring is not sufficient to absorb the moments occurring. But if the two movable legs, namely base legs and scissor legs, fixed while driving, this fixation (locking) takes over the moments that occur, and the object can not detach from the gripping device.
  • the fixation of the base leg and the scissor limb is effected by a ball.
  • the ball is pressed on one side by a leaf spring through an opening in the base leg against a seat in the scissor leg.
  • the seat circumscribes a diameter that is less than the diameter of the ball.
  • the opening in the base leg has a slightly larger diameter than that of the ball.
  • the gripping arms In order to open the gripper now, the gripping arms must be released. This means that the ball has to be moved out of its locked position. This is done by, for example, provided on the rail shift gate, which presses the ball against the spring force of the leaf spring to the outside. Since the opening of the scissor leg is occupied by a tangential edge by forming a chamfer, which also forms the above-mentioned seat, now slides at an opening movement of the gripping arms against each other this tangential edge along the ball and presses the ball entirely out of the opening of the scissor leg. So both legs are released and can perform the necessary opening and closing movements. This type of locking is very efficient and causes virtually no friction forces during unlocking.
  • each gripper vehicle should still be assigned an identification feature.
  • This may be, for example, a barcode attached or attached to the vehicle, or possibly a data matrix code.
  • Read stations installed in the system allow conclusions about the position of each vehicle or object. Since, according to the present invention, each article is transported individually with its own gripper vehicle, it is also possible to identify each individual article over the coded carriage. With this identification, it is possible, for example, to remove faulty items from the market somewhere in the system. But it could also, for example, different bottle types are transported or stored on the same system and then, thanks to the vehicle identification, at a suitable location again separated from each other. This vehicle identification also makes it possible to carry out the individual travel time-term identification of each individual car, which in turn allows conclusions about the wear. This is a prerequisite for preventative maintenance. The use of a single identification is completely new in the PET packaging industry.
  • Another feature of the present invention refers to the fact that multiple gripper vehicles can be coupled together. Especially in curves, in which, for example, no drive through a belt od. For cost reasons. Like., It is of great benefit to couple individual vehicles together, and thus the vehicles to push through the curves or pull, not the belt drive be recorded. In an unpowered corner, the still driven rearmost vehicles of a composition push the front vehicles through the curve until the foremost vehicles pass through again The drive is detected and driven so that they pull the rear vehicles by itself through the curve.
  • the coupling is effected by means of a magnet, which cooperates with a spring of the front vehicle.
  • a spring also has the advantage that when driving on a vehicle to the next shocks and bumps are substantially cushioned.
  • a lid is provided on the gripper vehicle, which takes over the cover of the opening of the object to be transported and absorbs the accumulating dirt.
  • an item for special items in the so-called aseptic area, it may even be necessary to seal an item (bottle) absolutely tight during transport. This can be done with a plug which is assigned to the inner hook. When receiving the bottle, this plug is lowered into the opening, so that the opening is completely closed and the inside of the bottle is protected from external influences.
  • the lid is preferably supported against a coil spring.
  • the rail is a conventional rectangular profile.
  • This profile offers many advantages.
  • the production of the profile is very simple and inexpensive, which is very worthwhile for distances of several hundred meters.
  • the rectangular profile can be bent with little effort into the desired shape, so that bows or spirals easy to realize. Thanks to the shape of the profile, the position of the vehicles is clearly defined, even torques that occur through the system or the vehicles can be recorded on the profile.
  • switches are preferably required in the system, which allow separations. If there are points in a system, this opens up the possibility of opening the system, that is, it does not necessarily have to be a closed circuit.
  • a particular advantage of the present invention is the simple design of a switch, which is possible thanks to the above-mentioned profile. Of great importance are fast switching times of the switches to achieve the most efficient, highly dynamic and energy-saving system. Switching times are directly linked to the switching path to be overcome, so small switching distances are particularly important.
  • the vehicle according to the present invention is built as lean as possible in the area where interaction with the switch can take place in order to minimize the necessary shift travel.
  • the switch only consists of a rail strip, which is connected to the actual rail.
  • the switch is moved from one to the other rail guide. This can be done by a simple pneumatic drive or with a solenoid.
  • only one stop can be provided.
  • the switch does not consist of one piece, but of a plurality of leaf springs, which are stacked on each other.
  • the flexible rail strip which makes up the switch, softens in the desired direction of movement, which allows faster switching times.
  • the switching forces are thereby considerably smaller. Thanks to this structure in layers, it is also possible to layer different materials on each other, which allows a lot of flexibility in terms of stiffness, forces, minimal friction, etc. Possible materials besides spring steel and plastics, fiberglass, composites and carbon fiber materials in question.
  • the rail strip is constructed in one piece.
  • it may consist of composite materials, carbon fiber materials or fiberglass.
  • the pressure piece is preferably assigned to the outer gripper a counter-holding spring, which the opening area of the bottle against the pressure piece suppressed. This ensures a secure mounting of the object on the gripper vehicle.
  • each vehicle has a drive pin which can be received in slots of a drive wheel.
  • the vehicles eintakten or singulate, on the other hand, but they can also be moved.
  • the rotating drive wheel which has the slots at fixed intervals, can be a variety of vehicles poke.
  • Another possibility is the design of the drive with a friction wheel. Thanks to the intentionally flat rear wall and head portion of the inventive gripper vehicles, it is possible to use such friction wheels as a drive, which can move the vehicles along the rails. Especially in places where the friction is greater than normal, for example, where the transport lock is unlocked, this can be of great importance.
  • the use of the friction wheel also opens the possibility to push many vehicles and thus bridge sections without their own drive. Furthermore, there is some storage space available.
  • the guide means protrude from the guide means protrusions, which at least partially rest against the object.
  • the guide means is a round belt, wherein this has an inner, fixed tensile strand, which is surrounded for example by a plastic jacket. On and / or in this plastic casing are then the projections.
  • this may be a coil spring made of steel.
  • This round belt has the outstanding advantage that it can follow any course of the rail in the room. He can follow every spatial curve.
  • the entire system is stowable, i.e., vehicles may stall while the round belt is moving.
  • the belt simply slides along the object, i.e., the entire drive section need not be shut off when the vehicles need to be stowed.
  • This is energy-related and of overall time management ago of great importance, since only the jammed objects must be accelerated again, but not the entire drive section.
  • the possibility of jamming also offers great advantages in the places where the articles have to be clocked in, as this allows the necessary dynamic pressure to be generated without additional devices. The same is true when stopping, for example, in front of a switch, also here does not have to be shut down the entire drive section.
  • This round belt with or without low-expansion core has a very hard, but also highly flexible outer skin, which allows a three-dimensional belt guide in the room with tight bending radii and minimal bending work. This results in a very good efficiency. If, for example, an object is clamped between two round belts, it can be moved.
  • the coil spring prevents excessive abrasion and thus increases the life of the entire transport unit, since the abrasion can be reduced to a minimum thanks to the coil spring, the associated pollution is smaller, which is crucial especially for transport goods in the packaging industry of food.
  • a magnetic connection is made between the article and the guide means.
  • the object can be connected directly to the guide means, or it can also be a transport vehicle od. Like. Switched for the object in between.
  • the guide means is not coupled directly to the vehicle, but preferably via a force generated by magnetism.
  • the transport of vehicles is designed very flexible, in particular, the vehicles can also jam, which is urgently required for larger facilities. If, for example, a processing station fails at short notice, the objects must be stopped in front of this processing station. In the systems known hitherto, only the entire system can be shut down here, so that the objects which are still in intact processing stations are not treated further. This is undesirable.
  • a permanent magnet cooperates, which is arranged in or on the vehicle or vice versa.
  • a flat toothed belt is provided instead of a round belt.
  • this has the advantage that a higher level ferromagnetic density than the round belt is generated and thus, for example, the transport of the vehicles is improved vertically upwards and the braking behavior is more favorable, but the belt has the disadvantage that he a rail only in one Level can follow, but not by spatial curves. Thus, the transport is not possible in three dimensions. The same applies to a steel belt as a drive option.

  • the vehicles 2 are assigned a friction wheel 48. This friction wheel 48 is occupied by a ring 49 of frictional material.
  • a rail 52 is illustrated, along which a gripper vehicle 53 runs.
  • This gripper vehicle 53 has two gripper arms 54.1 and 54.2, which are connected to each other via a rotation axis 55.
  • the gripper arms 54.1 and 54.2 open like a scissor, with an outer gripper 56 separates from an inner gripper 57.
  • a roller 58 On the axis of rotation 55 sits a roller 58, which runs off an upper edge 59 of the rail 52. This roller 58 cooperates with two further rollers 16 and 17, each of which runs a lower edge 62 of the rail 52.
  • an axis of rotation 63 of the roller 60 sits in the gripping arm 3.1, while a rotation axis 64 of the roller 61 is connected to the gripping arm 3.2.
  • the gripper arms 54.1 and 54.2 can be opened or closed.
  • a permanent magnet 66 which cooperates with a round belt 67 for driving the gripper vehicle 2.
  • a section of this round belt 51 is shown enlarged in FIG.
  • the round belt 67 is constructed in three parts. Inside there is a string of tension 68 as a soul, for example made of metal or kevlar. To this pull string 68 around a plastic sheath 69 is provided, which is looped by a coil spring 70 made of a ferromagnetic material. This coil spring can either be slipped over the plastic sheath or poured into it.
  • FIG. 1 The operation is also clearly visible in FIG. There, a plurality of gripper drivers 53 are arranged on a rail 52, which leads upwards. They transport objects 23, namely PET bottles.
  • the course of the rail 52 is also followed by the round belt 67, wherein it can be seen that the PET bottles 23 can accumulate on the rail 52 before and after the curvature.
  • the round belt 67 Through the round belt 67, the entrainment of gripper vehicles 2 in any spatial arrangement of the rail 52 is possible.
  • the round belt 67 is replaced by a toothed belt 71.
  • this toothed belt are not shown in detail, ferromagnetic elements through which a higher ferromagnetic density than the round belt can be generated. This has advantages when transporting gripper vehicles vertically upwards or when braking, but with a toothed belt 71 no spatial curves can be driven. The same applies to a steel strip 72, as indicated in FIG.
  • preforms 65.1 are moved along guide rails 73.1 and 73.2.
  • the round belt 67.1 or 67.2 does not act magnetically, but positively.
  • Both round belts 67.1 and 67.2 attack the preforms 65.1 in their neck area.
  • a force-fit entrainment of the preforms 65.1 takes place along the guide rails 73.1 and 73.2.
  • a plurality of carriages 75 are to be moved on a base 74. This is also done by the round belts 67.1 and 67.2, which are guided in corresponding grooves 76 in the base 74.
  • 75 corresponding insertion grooves 77 are formed in the bottom of the carriage. If the round belts 67.1 and 67.2 are moved along the double arrows, they take the carriages 75 with them. In this case, this happens rather form-fitting.
