Definitions

  • Can tapes for example as a result of the manufacturing process used or as a result of being provided via a reel, only be provided in a limited length and it is desired in a processing process for the tape that this processing process is carried out with a tape strand that is longer than the length that can be provided Band, it is necessary that an end section of a first band is connected to a starting section of a second band, with which a longer band strand formed from both bands is produced. It is quite possible that a large number of bands are connected to one another in this way, with the result that the length of the band can be further increased.
  • the invention relates to a method that can be used in this context for connecting an end section of a first band to an initial section of a second band.
  • the invention also relates to a ribbon splicer, a processing system, and a new use.
  • a possible field of application of the method and the tape connecting device includes tapes in the form of strip-shaped security tapes for security documents such as bank notes or entry tickets.
  • security tapes are intended to make forgery of the security document difficult or impossible as copies of the security tape are difficult to imitate, making an unauthorized copy easily recognizable as such.
  • the security tape can be embedded in a carrier material, in particular paper.
  • the security tape can be a plastic tape which is equipped with security features such as holograms.
  • the security tape is provided on a reel, unrolled from this and fed to the processing process, which here consists of the production of the security document. In the manufacturing process, the security tape is embedded in the carrier material.
  • connection section of the two security tapes must then be used in the further processing process (possibly together with the security document in which this connecting section is then arranged) are discarded.
  • DE 35 40 324 A1 shows a method for connecting two textile threads by means of compressed air.
  • two textile threads consisting of many individual twisted fibers are initially twisted at the ends. The two ends are then spliced together by twisting. After splicing, the two textile threads are held together due to the frictional force between the individual fibers and the self-locking that occurs under tensile load.
  • EP 1 209 115 A2 proposes for a splicing connection of a winding material in connection with the production of a cross winding to heat the winding material in the area of a splice head, the heating being said to be advantageous for the splicing connection of different types of yarn.
  • DE 33 36 202 A1 it is described as known to join two ribbons formed by filament yarns via machines with automatic knotters, air splicers or mechanical splicers, the disadvantage being described here that the known joining methods require the ribbons to rest during the production of the joint, which involves stopping and Restarting the processing process to which the filament yarn is fed is conditional.
  • DE 33 36 202 A1 suggests feeding a first yarn thread from a first bobbin via a thread eyelet, a slotted thread guide and a first splice chamber with a downstream thread guide eyelet to a testing device.
  • a stationary second thread of thread which has been taken from a second bobbin, extends.
  • the loose end section of the second yarn thread is held by a clamping point below the first yarn thread and in front of the first splice chamber.
  • a carriage is moved vertically upwards.
  • the carriage carries an electrically operated cutting device, a pull-down device and a second splicing chamber arranged between two slit thread guides.
  • the second yarn thread enters the slotted thread guide carried by the carriage and the upwardly open second splice chamber from above.
  • the second splice chamber is pressed against a frame-mounted counter plate that is not moved with the slide, with the result that the splice chamber is closed at the top.
  • the first, continuously conveyed yarn thread and the second, still resting yarn thread extend parallel to one another at a small distance in the second splice chamber.
  • the second yarn thread is then released by loosening the clamping point and the second splice chamber is acted upon pneumatically, with which the two yarn threads are swirled and spliced together.
  • the first thread can take the second thread with it.
  • the not yet spliced free end region of the second thread with the first thread also enters the first splice chamber, which means that this end region of the second thread can be entangled with the first thread.
  • DE 2 119 410 A1 discloses a connection of ends of glass fiber multifilaments by sewing the overlapping ends with an elastic thread which presses the two ends together, with which they are frictionally connected to one another.
  • JP S 60-61452 A discloses the interlocking connection of two ends of strips.
  • a rectangular through recess is made in a first end of a first band.
  • a second end of the second band is provided with groove-like recesses such that the cross section of the second end remaining in the area of the recesses corresponds to the cross section of the rectangular through recess of the first end.
  • the second end is guided through the through recess of the first end in such a way that the second end is received in the region of its recesses in a form-fitting manner in the through recess of the first end.
  • the document discloses a pair of pliers that can be used to produce the connection.
  • the invention relates to a method with which an end section of a first (in particular elongated) band can be connected to an initial section of a second (in particular elongated) band.
  • a ribbon strand is created that has at least the first ribbon and the second ribbon and the length of which is the sum of the lengths of the first ribbon and the second ribbon (minus the length of the connecting section of the same or minus the sum of the lengths of the starting section of the second belt and the end portion of the first band).
  • an "elongated band” refers in particular to a band whose length corresponds to at least 1,000 times, 10,000 times, 100,000 times or 1,000,000 times the greatest transverse extension of the band and / or which is at least 100 m long , 1 km or 10 km.
  • the ribbon strand is fed to a processing process in which an end product having at least one further component is produced with the ribbon strand and / or the ribbon strand is processed.
  • the tape strand is fed to a processing process in which the security tape is embedded in the base material of the bank note, in particular an aqueous suspension or mash of the paper or cotton paper of the bank note.
  • the end section of the first band is connected to the starting section of the second band via a liquid arranged in between.
  • the liquid connects the end section of the first band and the starting section of the second band via an adhesion, thus forming a band strand comprising the first band and the second band.
  • water can be used as the liquid, with water also being used as a liquid in the pulp of the paper or cotton paper.
  • the feed should not change during the change from the first belt to the second belt (apart from the fact that the overlapping two belts are fed to the processing process in the connecting section of the two belts).
  • the first band is conveyed at a distance from the starting section of the second band, with the second band preferably not being moved or not being conveyed in its longitudinal direction.
  • a wetting from the aforementioned liquid is applied to the end section of the first tape.
  • the wetting can be applied from the liquid to the starting section of the second band.
  • the starting section of the second band and / or the end section of the first band is moved via a combining device in such a way that the distance between them is reduced.
  • the invention encompasses both embodiments in which the combining device actively moves a band and embodiments in which the combining device merely releases the band, with which it can be moved and for example, by its own weight in the direction of the other belt as a result of its own weight can "fall down".
  • the starting section of the second band and the end section of the first band come to rest against one another in a connecting section, which can also be done with the generation of a pressing force.
  • an adhesive connection is produced between the bands. With or after the adhesive connection is established, the first band and the second band move together to the processing process.
  • the first belt is moved at its conveying speed while the connection is being established, while the second belt is initially not subjected to any conveying movement (apart from the movement to approach the first belt), for the joint movement of the first belt and the second belt to the processing process, the second belt can be accelerated to the conveying speed of the first belt.
  • the connection provided by the adhesion is already sufficient to ensure a force to accelerate the second belt, so that the second belt is moved along with the first belt (which in some circumstances also results in increasingly decreasing slip in the adhesively connected connecting section can be done).
  • the adhesive connection only provides a portion of the force required to accelerate the second band via the liquid, this portion for example less than 50%, less than 40%, less than 30%, less than 20% or even less than 10% of the total force acting to accelerate the second belt can be.
  • the force to accelerate the second belt to produce the common movement of the first belt and the second belt is partly caused by a drive, that is, not only by the force that is generated in the area of the adhesive connection.
  • a conveyor roller can be driven via a separate drive, the separate drive being set in motion by the uniting device before or when the second belt is pressed against the first belt.
  • Such a drive can be arranged in the working area of the combining device or in front of or behind the same and, for example, drive the belt which at least partially wraps around the conveyor roller via friction with the driven conveyor roller.
  • the starting section of the second belt lies against a first conveyor roller. If the starting section of the second belt is then moved by the uniting device in such a way that the distance between the two belts is reduced until they come into contact with one another, the first conveyor roller, which can be part of the uniting device, will move in the direction of the (preferably uninterrupted conveyor) ) first volume. At the end of this movement, the first conveyor roller then interacts with a second conveyor roller, the jacket surface of the first conveyor roller preferably forming frictional contact with the jacket surface of the second conveyor roller. The second conveyor roller rotates in accordance with the movement of the uninterrupted first belt.
  • the second conveyor roller can be designed as a motor-driven conveyor roller via which the uninterrupted conveyance of the first belt is caused or supported.
  • the second conveyor roller is wrapped around by the first belt and, as a result of the conveying movement of the first belt, the belt sets the second conveyor roller in rotation.
  • an acceleration force is exerted on the first conveyor roller which, as a result of the second belt wrapping around the first conveyor roller, leads to a drive force.
  • This driving force accelerates the starting section of the second band for the common movement of the end section of the first band and the starting section of the second band after the adhesive connection has been established.
  • the two bands are connected via the adhesive connection, which means that part of the accelerating force or only that the two bands are held together can be ensured. At least part of the force for the acceleration of the second belt is thus taken from the conveying movement of the first belt or an associated conveying roller.
  • Another aspect of the method according to the invention is dedicated to the requirement that the first belt must be guided by at least one stationary guide device with regard to the position, the conveying direction and the alignment of the belt around its longitudinal axis.
  • Two slide rods or guide rollers can be used as possible stationary guide devices.
  • the two slide rods or guide rollers can extend parallel to one another. It is possible that a gap is formed between the slide rods or guide rollers through which the first band can pass, whereby horizontal guidance can be ensured when the slide rods or guide rollers are oriented vertically. It is also possible, however, for the first band to be deflected in opposite directions on the outer surfaces of the slide rods or guide rollers.
  • an alignment roller is used as a guide device, via which the alignment of the cross section of the first strip around its longitudinal axis can be changed.
  • at least one deflecting roller is used as the stationary guide device, via which a change in the conveying direction of the first belt is possible in accordance with the wrap angle of the deflecting roller.
  • the guide device is an exit guide, via which the location and the orientation with which and at which the tape strand leaves the tape connecting device used can be specified.
  • the merging guide can be designed as a plate with a slot in which the two belts are arranged and guided one above the other and in which the two belts are laterally guided so that the belts lie on top of one another when the merging device moves into the active operating position becomes.
  • the aforementioned guide devices can have an adjusting device by means of which their position and orientation can be adjusted.
  • the invention proposes that an electronic control unit be used in the method.
  • the components involved can be controlled by means of the electronic control unit (and an associated control logic), with a "control" also being intended to include regulation within the scope of the invention.
  • a holding device can be actuated via the control by the control unit, via which an end of the second band can be held and fixed.
  • the control of the control unit it is possible for the control of the control unit to actuate a wetting device by means of which the first band and / or the second band are wetted with the liquid.
  • the control of the control unit controls a cutting device. Any control philosophy can be used here.
  • the holding device and / or the clamping device in an operating position not energetically charged by the control unit, is in a position holding or clamping the second band (in particular as a result of the action of a spring), while the holding device or the clamping device is released energetic loading of the same by the control unit takes place (in particular against the effect of the aforementioned spring).

It is possible that several pneumatic actuators are used for the aforementioned devices. It is also possible, however, for a pneumatic actuator to be used in a multifunctional manner, in that it actuates both the clamping device and the cutting device.
  • the clamping device in a first partial stroke of the pneumatic actuator, can be transferred from the clamping position to a release position that releases the second band, in which the second band can be moved in its longitudinal direction, but is guided transversely to the longitudinal direction by the clamping device at a distance from the first band is.
