Definitions

  • the invention relates to a device for cutting Etikettierhülsen of a film tube, a device for applying a Etikettierhülse and a method for applying a Etikettierhülse.
  • shrink labels are used, which are cut from an endless tube to the correct length and then passed over the bottle. Subsequently, the bottle can be passed through a shrink tunnel, in which the labeling sleeve is then shrunk.
  • Other labeling sleeves such as flexible Etikettierhülsen, may be present on film tubes and used in the field of beverage bottling.
  • the object of the invention is to provide an improved device for cutting Etikettierhülsen.
  • a device comprises a knife actuating ring and a knife carrier, wherein the knives are rotatably mounted on the knife carrier and are mechanically coupled via the knife actuating ring.
  • Knife carrier and knife actuating ring are usually arranged coaxially. If the knife carrier and knife actuating ring are displaced in the direction of rotation in relation to each other in one direction, then the knives fold inwards due to the mechanical coupling via the knife actuating ring into the cutting position. Knife carrier and knife operating ring can both be referred to as a cutting wheel below. To fold back the knives, knife carrier and knife operating ring brought back to its original relative position.
  • inward in particular, in a substantially radial direction towards the center of the substantially understood annular contact carrier, ie in the direction of the label material to be cut.
  • the knife actuating ring and / or the knife carrier are rotatably mounted according to the invention.
  • the knife carrier and knife actuating ring run synchronously for this process.
  • a speed difference between the running speeds is generated in each case for a short time so that the knife carrier and knife actuating ring move in the direction of rotation.
  • the knife actuating ring or the knife carrier can be braked compared to the other cutting wheel.
  • the blades fold into the cutting position.
  • the cutting ring and knife carrier run synchronously, so that the position of the knife does not change. In order to fold the knives back out of the cutting position, this relative displacement must be canceled again after the cut.
  • the previously braked blade actuating ring or knife carrier can be accelerated in the direction of rotation for a short time compared to the other cutting wheel.
  • Speed in the direction of rotation is used in the text to increase the speed in the direction of rotation.
  • the device may also be designed so that first a cutting wheel, ie knife carrier or knife actuating ring accelerated in the direction of rotation and thus the relative position between the two cutting wheels is changed to unfold the cutting blade. For example, following a cut, the cutting blades can be brought back into the original relative position by braking the respective cutting wheel.
  • a cutting wheel is accelerated in the direction of rotation and the second cutting wheel braked at the same time to move the cutting wheels against each other. In order to restore the original relative position, then, for example, after cutting the previously accelerated in the direction of rotation cutting wheel braked again and the second, previously braked cutting wheel can be accelerated simultaneously in the direction of rotation.
  • Knife actuating ring and / or knife carrier are driven directly in a device according to the invention.
  • directly driven means that the knife carrier and / or the knife actuating ring, which is directly driven, is driven by a motor without a toothed belt transfer.
  • This may for example be the case when the knife carrier is connected and / or the knife actuating ring is directly and / or fixedly connected to a drivable component, wherein the movable components move the knife carrier and / or knife actuator ring.
  • a direct drive can be dispensed with a toothed belt.
  • such a device may be designed so that a cutting wheel is driven with a toothed belt and the second cutting wheel, which brakes for folding and folding the knife and accelerated in the direction of rotation, or is accelerated and decelerated in the direction of rotation, is directly driven.
  • knife actuating ring and knife carrier can be driven directly.
  • This can be advantageous, for example, since the space required for the device can thereby be reduced, since, for example, the motor can be integrated into an aggregate base plate. Also, for example, the blade unit can be pre-assembled and tested.
  • the direct drive for a cutting wheel by an electric motor in particular, for example, a torque motor done.
  • an electric motor can be present for each directly driven cutting wheel, which can drive the respective directly drivable cutting wheel.
  • one or two rotors of one or two electric motors drive the rotating parts.
  • each rotor is part of exactly one electric motor and usually each electric motor comprises exactly one rotor.
  • each directly driven cutting wheel can be connected to a rotor of an electric motor or comprise a rotor of an electric motor or be part of the rotor, wherein this connection is preferably not detachable.
  • knife actuating ring and / or knife carrier can each be connected to a rotor of an electric motor, wherein the connection is preferably not solvable.
  • Non-releasable in this context means a solid connection, which is not held by releasable means such as screws, but by solid compounds, such as glue, nails or welds.
  • the connection between a directly driven cutting wheel and an associated rotor of an electric motor can also be made detachable.
  • the rotors of the electric motors may be coaxial with each other and / or coaxial with the knife actuating ring and the knife carrier and / or its axis (s) parallel to the axis of rotation of the cutting knife or blades.
  • This can be advantageous since, for example, when the two cutting wheels are displaced relative to one another, the knives coupled to the knife actuating ring pass through the shift can be moved quite easily.
  • a space-saving arrangement of the device parts can be achieved thereby.
  • the device for cutting off labeling sleeves (also referred to as device in the text) is designed in such a way that the one or more electric motors belonging to the one or more rotors of the electric motor (s) are fastened to the stationary part of the device.
  • a fixed part of the device is hereby designated the part which is not moved during operation of the device.
  • a movement of the whole device is not taken into account.
  • Such stators of the electric motor or motors can also be coaxial with one another and / or with one or both rotors be arranged of the electric motors or the device.
  • the knife carrier and / or the knife actuating ring may be individually controllable.
  • the control can take place, for example, by a central control unit, which can take into account, for example, the control and / or position of the respective other cutting wheel.
  • the optional position detection of knife actuating ring and / or knife carrier can be incorporated.
  • the knife carrier and / or knife actuating ring may be mounted on the stationary part of the device via one, two or more ball bearings.
  • the knife carrier can be mounted on the stationary part via a first ball bearing and the knife actuating ring can be mounted on the knife carrier via a second ball bearing.
  • the blade actuating ring may be mounted on the stationary part via a first ball bearing and the blade actuating ring may be mounted on the blade carrier via a second ball bearing.
  • both the knife actuating ring and the knife carrier may be mounted on the stationary part of the device via a respective ball bearing.
  • the device may include a sensor that can detect the position of the blade carrier.
  • a sensor that can detect the position of the blade carrier.
  • the position relative to the stationary part of the device can be detected.
  • a sensor may include, for example, a scanning head, for example, a hollow shaft encoder.
  • the device may detect a sensor that can detect the position of the blade actuating ring.
  • a sensor that can detect the position of the blade actuating ring.
  • the position relative to the stationary part of the device can be detected.
  • a sensor may include, for example, a scanning head, for example, a hollow shaft encoder.
  • a sensor that can detect the position of the blade carrier and / or a sensor that can detect the position of the blade actuating ring can detect the position, for example, by means attached to the stationary part of the device or by the stationary part of the device.
  • a position detection can be carried out on the basis of a hollow shaft encoder, so an aid may be formed, for example, as a donor wheel of a hollow shaft encoder.
  • the position detection may be based on one or two optical sensors that may detect, for example, measurement scales attached to the stationary part of the device.
  • the senor for detecting the position of the blade actuating ring and / or the sensor for detecting the position of the blade carrier may be attached to or included in the stationary part of the device. At the same time, aids for detecting the position on the knife actuating ring and / or the knife carrier can also be attached to or covered by this or these.
  • the fixed part of the device comprises a hollow shaft, in particular, it may be formed as a hollow shaft.
  • the device may include four individual cutting blades on the knife carrier. Such blades are referred to in this text as a knife.
  • the device may alternatively comprise only one or two or three cutting blades on the knife carrier.
  • a significantly faster cut can be achieved because each knife only has to cut a portion of the circumference of the film tube.
  • the knives are arranged at equidistant intervals on the knife carrier. With such a device, for example, a cut can be carried out within less than 100 ms, in particular less than 60 ms, in particular less than 40 ms.
  • the direct drive can also have a positive effect, since in some cases, the cutting speed can be increased.
  • the invention also includes a device for applying a labeling sleeve, which comprises a previously described device for cutting labeling sleeves of a film tube (which is also referred to as a device).
  • the invention also encompasses a method for applying a labeling sleeve according to claim 13 with a device for cutting labeling sleeves from a film tube (which also called device).
  • the method comprises synchronously driving knife carrier and knife actuating ring.
  • the knife carrier and / or the knife actuating ring is driven directly.

  • the knife actuating ring or the knife carrier can be braked compared to the other cutting wheel. As a result, the blades fold into the cutting position. During the cut, the two cutting wheels can then run synchronously again.
  • this relative displacement In order to fold the knives out of the cutting position, this relative displacement must be canceled again. This is usually done by again briefly generating a speed difference between the running speeds until the relative displacement is canceled again, ie the two cutting wheels are in particular again in the original relative position and can continue to be driven synchronously.
  • the previously generated speed difference for the same duration with the opposite sign can be applied to the cutting wheel whose speed has previously been changed.
  • the previously braked blade actuating ring or knife carrier can be accelerated in the direction of rotation for a short time compared to the other cutting wheel.
  • a speed difference and thereby induced displacement of the cutting wheels to each other can also be generated by the fact that at the same time a cutting wheel braked and the other is accelerated in the direction of rotation. For returning to the original relative position then the operations can be reversed, so for example, the previously braked cutting wheel accelerated in the direction of rotation and the previously accelerated in the direction of rotation cutting wheel are decelerated.
