Definitions

  • the invention relates essentially to a device for changing bobbins comprising a holder for a first bobbin, a holder for a second Bobine, a device for connecting one running from the first Bobine Material web with a material web running in from the second bobbin and means for collection and disposal not for processing suitable strips of material both material webs.
  • the invention further relates to a method for changing Bobbin comprising the steps: feeding a running material web from a old, almost completely expired bobbin and an incoming material web from a new, full bobbin to a device for connecting the material webs, Joining both material webs and disposing of them are not suitable for processing Strips of material, namely a leader of the new bobbin and a residual material the old bobbin.
  • Cigarettes It is common in the tobacco processing industry to manufacture e.g. of Cigarettes are the webs of cigarette paper, filter paper or the like are wound up on so-called bobbins, to connect automatically so that one continuous production can take place. This can be done by knurling, embossing, gluing or other common connection techniques. This will be an expiring Material web of an already largely developed bobbin with a tapered one Material web connected to a new, full bobbin.
  • the leader or the residual material is separated Separating elements, e.g. Knives separated from the core of the Venturi principle Bobbins loosened by unwinding and vacuuming and into a pipe system Receiving container, the so-called shot box, promoted. There it will be The leader and residual material formed shot material compressed by the separated Strips of material are compressed with a tamper or the like. Once the Shot box has reached a certain level, it is manually emptied and cleaned.
  • Separating elements e.g. Knives separated from the core of the Venturi principle Bobbins loosened by unwinding and vacuuming and into a pipe system Receiving container, the so-called shot box, promoted. There it will be The leader and residual material formed shot material compressed by the separated Strips of material are compressed with a tamper or the like. Once the Shot box has reached a certain level, it is manually emptied and cleaned.
  • the known devices and methods have the disadvantage that due to the complex structure, they have a large variety of parts, which is too high Manufacturing and maintenance costs. Furthermore, the devices and the process - due to the Venturi nozzles - very noise-intensive. Is too disposal, in particular emptying the firing box, or cleaning the same as well as the environment very expensive. Furthermore, the disposed Residual material has a very large volume on what handling and disposal overall difficult.
  • the means at least one winding device for receiving and for disposing of a strip of material not suitable for processing.
  • the wrapping device can be a compacted, so compressed bale Form shot material that are easily passed into the shot container can.
  • This defined recording of the shot material ensures easy Handling as well as a simple and clean, especially dust-avoiding Disposal of the shot material. Noise reduction is also particularly advantageous by providing the winder for the shot material.
  • the winding device is advantageously for receiving and disposing of one Leader of the new, full bobbin in the direction of transport of the material web behind the Device for connecting and the other winding device for receiving and for Dispose of residual material from the old, almost completely expired bobbin in Transport direction of the material webs arranged in front of the device for connecting. This saves and takes up the whole in a space-saving manner Shot material guaranteed that can also be easily removed without the Contaminate the environment.
  • At least one winding device additionally designed as a release agent.
  • this allows individual parts can be saved, which reduces costs and maintenance.
  • the handling is particularly simplified, since the separation by the anyway rotating winding devices or coils can take place.
  • the task is accomplished by a method with the aforementioned Steps solved in that at least one strip of material is wound up and is disposed of automatically. This means that compressed bales cannot be removed from the Processing suitable material strips form a much simplified and enable improved, dust-free disposal.
  • both the leader and the residual material are wound up and thereby compressed, whereby the volume of the weft material overall further reduced.
  • the devices shown in the figures are used for changing bobbins, in particular for connecting two material webs when changing bobbins ongoing splicing in a reel machine.
  • the device 10 for changing or connecting bobbins comprises a first one Recording 11.
  • a first bobbin 12 is arranged on this recording 11.
  • the bobbin 12 is formed from a core 13 on which a material web 14 is wound.
  • the device 10 has a further receptacle 15 for receiving a second bobbin 16.
  • the bobbin 16 also has a core 17 on which one Material web 18 is wound.
  • Both bobbins 12, 16 each have their own Drive 19 or 20 can be driven.
  • the two bobbins 12, 16 follow in Transport direction of the material webs 14, 18, a device 21 for connecting the Material webs 14, 18.
  • the device 21 is off two rollers 22, 23 are formed, each with its own drive 24 or 25 feature.
  • the peripheral surface 26 of the roller 22 forms a smooth knurled surface 27.
  • Die Roller 23 has a segment 28 which on its side facing away from roller 23 Surface 29 has a structured knurled surface 30.
  • the distance between the rollers 22, 23 or their axes of rotation 31, 32 is variably adjustable and depending on the Material thickness of the material webs 14, 18 to be connected selected such that the Material webs 14, 18 by pinching between the roller 22 and the segment 28 connect. Other means of connection, for example gluing devices or the like can also be used.
  • the material webs 14, 18 in front of the Device 21 is arranged a first winding device 34.
  • the winding device 34 is arranged virtually within the material web 14 in such a way that the material web 14 runs through the winding device 34 or is threaded therein.
  • the winding device 34 has a coil 35.
  • the coil 35 can be driven to rotate, specifically by a drive 36.
  • a second one Winding device 37 arranged, which is also a rotatingly driven coil 38th having.
  • the coil 38 is connected to a drive 39.
  • the coil 38 is arranged within the material web 18 such that a free end 40 of the Material web 18 runs through the winding device 37 or is threaded therein.
  • the coils 35, 38 which are also replaced by other conventional winding elements can have recordings for receiving the material webs 14, 18.
  • the Recordings can e.g. be formed by a slot 41 (see Figure 3).
  • a another possibility is e.g. therein, several around the circumference of a disk 42 to provide distributed pins 43.
  • the pins 43 are spaced apart from one another and evenly distributed over the circumference, so that a slot 41 is also formed (see Figures 2a to 2c).
  • All drives 19, 20, 24, 25, 36, 39 are on a common control 51 connected.
  • the controller 51 controls the times and the rotation speeds of the individual bobbins 12, 16 or rollers 22, 23 or spools 35, 38.
  • the times and the rotational speeds of the bobbins 12, 16, the Rollers 22, 23 and the coils 35, 38 can be individually controlled or regulated.
  • the means that acts as a suction bar 60 is preferably above the material web 14 is formed, arranged adjustable.
  • the squeegee 60 acts as soon as it engages with the material web 14 is that a tensile force is applied to the material web, which acts opposite to the direction of transport according to arrow 33.
  • the suction bar 60 can but can also be replaced by other conventional means of fixation.
  • This Means has a so-called dancer device 62, which consists of several roles or Rolling is formed. At least one of the rollers is spring loaded and in the direction of the Arrow 62 movable. The material web 14 is threaded into this dancer device 62. In the event that the subsequent machine needs more material than actually from the bobbin 12 is delivered, this is pulled from the memory or buffer so that Speed differences during the transport of the material web 14 can be compensated. The principle also works accordingly for other material webs.
  • strip-shaped material webs 14, 18, such as cigarette paper are processed continuously.
  • the cigarette paper is unwound from a so-called bobbin.
  • the running material web 14 of the old bobbin 12 must be connected to an incoming material web 18 of a new, still full bobbin 16.
  • a first one Strip of material 53 which must be disposed of, is the so-called leader, which at Opening a new, full bobbin 16 is created.
  • a second strip of material 52 is that on the core 13 of the bobbin 12 remaining material of the old, almost empty Bobine 12
  • the cigarette paper is unwound from a bobbin 12.
  • the cigarette paper that is to say the material web 14 or a material strip 52, is threaded into the spool 35 and passed through the device 21 for connecting the material webs 14, 18.
  • the material web 14 is drawn off via rollers 45, 46 in the direction of further processing (see arrow 47) at a predetermined transport speed v 1 .
  • the material web 14 Before the material web 14 is completely unwound from the bobbin 12, it must be connected to the material web 18 of the new full bobbin 16 during operation, that is to say with continuously conveyed material webs 14, 18.
  • the material web 18 is already threaded into the device 21 before the connection, so that the material webs 14, 18 run approximately parallel to one another in the area of the device 21.
  • the free end 40 or the material strip 53 of the material web 18 is threaded behind the device 21 in the spool 38.
  • the spool 38 is permanently driven, so that the material web 18 wound on the bobbin 16 is biased, since the bobbin 16 is initially stationary. Therefore, the material web 18 is in a stationary state.
  • the coil 38 which acts like an endless spring, therefore holds the material web 18 or the material strip 53 under tension.
  • the coil 38 is designed with an inertial mass such that the coil 38 cannot follow rapid changes in speed.
  • the bobbin 16 is first accelerated by knurling before the actual connection process is initiated, specifically to a speed v 2 that is greater than the original transport speed v 1 the material web 14 during processing.
  • a speed v 2 that is greater than the original transport speed v 1 the material web 14 during processing.
  • the material web 14 which is initially conveyed at the transport speed v 1 during processing, is braked to a speed v 3 , where v 2 > v 1 > v 3 .
  • the braking of the material web 14 takes place essentially via the drive 19 of the bobbin 12.
  • the suction bar 60 is preferably switched on shortly before the actual connection process, which virtually holds the material web 14 or the material strip 52 or a tensile force on the material web 14 against the applied by the arrow 33 indicated transport direction. As soon as the suction bar 60 is in engagement with the material web 14, the tension of the material web 14 between the device 21 and the suction bar 60 rises further without changing the speed.
  • the material difference resulting from the braking of the material web 14 - due to the drive 19 - is compensated for by the dancer device 62, which is designed as a buffer or memory, in the case of continuously ongoing processing behind the device 21 at the speed v 1 .
  • the tension of the web that is to say of the material strip 53 behind the device 21, increases.
  • the increase in tension is primarily a result of the speed difference between the material web 18 being conveyed at the speed v 2 prior to the contact of the segment 28 with the roller 22 and the speed of the material web 18 during the contact between the segment 28 and the roller 22, which is preferably corresponds approximately to the speed v 1 , but in any case is less than v 2 . Due to the inertia of the coil 38, this cannot follow the abrupt speed difference v 2 v 1 .
  • the material web 18 is braked from v 2 to v 1 when the segment 28 comes into contact with the roller 22, while the bobbin 38 continues to rotate with v 2 .
  • the material web 18 or the material strip 53 is placed under tension between the winding device 37 and the device 21 for connecting, which leads to the material strip 53 being separated behind the device 21 under a certain load.
  • the material strip 53 usually tears at the point weakened by the edge 49.
  • the spool 38 is then driven in rotation until the torn end of the material web 18, namely the material strip 53, is completely wound up and thereby compressed.
  • the compressed, wound leader is then automatically disposed of by being pushed off the spool 38.
  • either the coil 38 itself or an auxiliary device such as the stripper disk 44 is moved axially.
  • the compressed shot material falls into a container (not shown) that can be easily lifted and emptied.
  • connection process is continued by rotating the rollers 22, 23 in the opposite direction, in that the segment 28 rolls on the peripheral surface 26 of the roller 22.
  • segment 28 and the roller 22 are driven at a speed of preferably about v 1 , but in any case at a speed which is greater than the speed v 3 , but the material web 14 by the drive 19 to the speed v 3 has been braked, a speed difference is generated which leads to an increase in the tension of the material web 14 or the material strip 52 between the device 21 and the bobbin 12.
  • the device 21 now connects the material webs 14 and 18, specifically at the speed v 1 of the pulling-off machine, which is arranged behind the changing device in the transport direction, the additional tensile force exerted on the material web 14 by the suction bar 60, or the resultant force increased web tension between the device 21 and the suction bar 60 cause the material web 14 to tear in the area of the device 21.
  • the spool 35 Shortly before a rear edge 50 of the segment 28 is in contact with the roller 22 or immediately after the connection process has ended, the spool 35 is driven so that the material web 14 or the material strip 52 is wound up. The spool 35 is driven in rotation until the material strip 52 is completely unwound from the bobbin 12 and wound on the spool 35.
  • the suction bar 60 acts as a catching device which holds the severed end of the material web 52 until the weft material is completely wound up. The remaining material is then automatically disposed of in the same way as the header.
  • the reusable core 13 can now be removed from the bobbin 12. A new, full bobbin is then placed on the receptacle 11, which in turn can be connected to the material web 18 of the bobbin 16 now running.
