Definitions

  • the invention concerns a cutting device for a web winder, said device comprising a frame construction and a cutting blade, by means of which cutting blade the web in the reel formed on support of the carrier drums can be cut off before new winding is started.
  • This prior-art carrier-drum winder comprises a rear and a front carrier drum, web cutting means, pushing means for the transfer of a complete reel from the carrier drums, and means for feeding a new reeling spool.
  • the cutting means and the feeding means are operationally connected with the pushing means so as to be displaced to their operation positions by means of a common support arm.
  • the carrier-drum winder includes a backup holder, which is pushed to project from between the carrier drums and which holds the web against the rear carrier drum.
  • the cutting means include a member for cutting off the web by means of a stroke-like movement of the cutting blade, said movement being directed at the area of the tip of the backup holder, towards the web portion placed between, and held tight by, said tip and the pushing means.
  • a cutting device for a web winder comprising a frame construction and a cutting blade, by means of which cutting blade the web in the reel formed on support of the carrier drums can be cut off before new winding is started, the cutting blade being fitted to move along a curved path of movement where said curved movement of rotation has been chosen so that the centre of rotation of the cutting blade is separate from the centre of rotation of the carrier drum to the effect that the position of the cutting blade in the lower position is substantially more distant from the carrier drum than in the upper position.
  • the object of the present invention is to provide an improvement over the prior-art web cutting devices.
  • a further object of the invention is to provide a cutting device which can be attached to the frame of any carrier-drum winder whatsoever.
  • the cutting device in accordance with the invention, a number of remarkable advantages are obtained.
  • the cutting device can be attached to the frame of any carrier-drum winder whatsoever.
  • the cutting blade of the cutting device can be passed into the gap between the carrier rolls either from below, from the front, from the rear, or from above.
  • auxiliary devices are, for example, a blow device for holding the end of the cut-off web, a web holding device, and a threading member, etc.
  • Figure 1 is a side view of a preferred embodiment of a cutting device in accordance with the invention.
  • Figure 2 is a side view of a second preferred embodiment of a cutting device in accordance with the invention.
  • Figure 3 is a side view of a third preferred embodiment of a cutting device in accordance with the invention.
  • Figure 4 is a side view of a fourth preferred embodiment of a cutting device in accordance with the invention.
  • Figure 5 is a side view of a fifth preferred embodiment of a cutting device in accordance with the invention.
  • the cutting device in accordance with the invention is denoted generally with the reference numeral 10.
  • the cutting device 10 comprises a frame 11, a synchronization tube 12, first arms 13 that are fitted pivotally, second arms 14 that are fitted pivotally, a cutting-blade frame 15 and a cutting blade 16, as well as a actuator 17.
  • the frame tube which is a part of the frame 11, is denoted with the reference numeral 11a.
  • the frame tube 11a passes in the transverse direction through the carrier-drum winder to the other side.
  • the cutting device 10 is applied in a carrier-drum winder which comprises a conventional carrier drum 18 as well as a carrier drum 19 consisting of a roll 19a and of another roll, not shown, and of a belt 19b.
  • the reel is denoted with the reference numeral 20.
  • the cutting blade 16 of the cutting device 10 is passed into the gap between the carrier drums 18 and 19 from below.
  • the cutting device 10 is attached to the frame construction.
  • the cutting device 10 shown in Fig. 1 operates as follows.
  • the movement of the actuator 17, e.g. a hydraulic cylinder, acts upon the first arms 13, which are linked with the second arms 14.
  • the pivoting movement of the arms 13 is synchronized by means of the synchronization tube 12.
  • the frame 15 of the cutting blade 16 is linked with the second arms 14.
  • the movement of the actuator 17 is transferred to the frame 15 by the intermediate of the arms 13 and 14, whereby the frame 15 of the cutting blade 16 and the blade 16, which is attached to said frame, obtain a curved movement of rotation in relation to the face of the carrier drum 18.
  • This curved movement of rotation has been chosen so that the centre of rotation of the cutting blade 16 is separate from the centre of rotation of the carrier drum 18.
  • the centre of rotation of the blade 16 can be chosen fully freely, provided that the centre of rotation of the blade 16 does not coincide with the centre of rotation of the carrier drum 18.
  • the dashed lines indicate the lower position of the cutting blade 16 and, in a corresponding way, the full lines indicate the upper position. From Fig. 1, it comes out clearly that in the lower position the cutting blade 16 is placed at a certain distance from the face of the carrier drum 18, and in the upper position the cutting blade 16 is placed very close to the face of the carrier drum 18.
  • the cutting proper of the web takes place either merely because the blade 16 is sharp enough to pass through the web that is placed tensioned on the reel 20.
  • the cutting of the web placed on the reel 20 may also take place so that the reel 20 is pushed by means of a pushing device in itself known, in which case the tensioned web forms a sufficient angle in relation to the cutting blade 16, whereby the web is cut off.
  • FIG. 2 illustrates the passing of the cutting device 10 in accordance with the invention into the gap between the carrier drums 18 and 19 from the side, i.e., in the present case, from the rear.
  • the carrier-drum winder comprises conventional carrier drums 18 and 19.
  • the passing of the cutting device 10 takes place similarly to Fig. 1, from below.
  • the carrier-drum winder is composed of conventional carrier drums 18 and 19. Further, in this embodiment, the cutting device 10 is provided with a blow device 21.
  • the embodiment shown in Fig. 4 is in the other respects similar to the embodiment shown in Fig. 1, but the cutting device 10 shown in Fig. 4 is provided both with a blow device 21 and with a web holder 22.
  • Fig. 5 shows a embodiment which is in the other respects similar to the embodiment shown in Fig. 1 except that, in the embodiment shown in Fig. 5, the cutting device 10 is provided both with a blow device 21 and with a web threading member 23.
  • the cutting device 10 in accordance with the invention operates during normal winding and during reel exchange as follows.
  • the blade 16 has been run down so that there is a sufficient space underneath the carrier drum 18.
  • the threading member 23 is placed underneath the carrier drum 18, and the cutting blade 16 of the cutting device 10 has been run to its extreme upper position.
  • the cutting blade 16 has moved to its extreme upper position through the gap between the carrier drums 18 and 19, in which case it is possible to carry out conventional cutting-off of the web.
  • the cut-off end of the web can be held in its position, e.g., by means of a blow device 21 shown in Figs. 3 and 4.
  • the cutting blade 16 is moved slightly down to permit fitting of a new spool into the gap between the carrier drums 18 and 19.
  • the reel exchange constitutes prior art, it will not be described in further detail in connection with the invention disclosed in the present application.
  • the cutting device 10 in accordance with the invention permits a very smooth and fluent exchange of reel.
