Definitions

  • the invention relates to a device for the continuous winding of a web of sheet material, in particular a paper web, according to the preamble of claim 1.
  • Such a winding device is known from US-A-47 44 526. It is also known as a pop roller. With such a pop roller a continuous winding of a paper web is possible. The paper web is deflected around a carrying drum and then wound onto a carrier axis, a so-called reel. The winding drive takes place in that the aforementioned carrier drum is driven and rests on the outer circumference of the winding being created.
  • a pivot arm is arranged approximately concentrically to the carrying drum, with which an empty carrier axis can be brought into the winding position when the previous carrier axis has been fully wound with the paper web.
  • the empty carrier axis is rotated by the supporting drum acting on its circumference.
  • a winding device for winding pressure-sensitive paper uses a first pressure roller, which is kept at a distance from the winding.
  • a second pressure roller with a soft pressure surface is provided in the feed direction of the paper web behind this first pressure roller. Due to the distance between the first pressure roller and the winding, air is drawn into the winding, particularly at high machine speeds. The second pressure roller prevents this air from being drawn in.
  • the second pressure roller with a soft surface lies against the surface of the roll with slight pressure.
  • DE-A-15 60 039 proposes another solution for achieving even pressure with the aid of a take-off and a pressure roller. A further winding during the roll change is also not provided here.
  • the carrier drum used per se for driving the winding and the carrier axis is converted into a guide drum during the winding operation following the change of the carrier axis, in order to guide the paper web into the gap between the pressure roller and the winding without any air in the Wrapping is included.
  • the known Poperoller system must be modified to provide its own winding drive for the carrier axis and to add a separate sensor-controlled pressure roller, which lies gently on the winding, prevents air inclusion and by sensor control and the corresponding advance of the carrier axis with the Wrap allows a soft wrap in connection with the advantageous pop roller system.
  • the surface of the guide drum is roughened, so that a particularly good guiding function of the carrier drum converted into a guide drum is ensured, while avoiding axial displacements of the web to be wound up.
  • the single figure shows a schematic side view of a device for the continuous soft winding of a paper web on a carrier axis.
  • a paper web P is fed from the left in the drawing and, after a first deflection around a roller 10, runs over a guide drum 12 and then passes into the winding 14 that can already be seen in the drawing.
  • the guide drum 12 rotates about an axis 16.
  • a pivot arm 20 with a receiving fork 22 is pivotably arranged about an axis 18 that is slightly offset from it, as is indicated by the dash-dotted circular arc 24.
  • An empty carrier axis 26 is inserted into the fork 22 in order to pivot it from the receiving position A shown in the drawing into an operating position B, which will be explained later.
  • a cylinder 28 is arranged on the swivel arm 20, with which a holding arm 30 can be actuated in order to hold the support axis 26 in the fork 22 when the swivel arm 20 is pivoted in the manner described above.
  • a pressure roller 32 which is attached via an auxiliary lever 34 to a pivot lever 36 which can be pivoted back and forth via a cylinder 38.
  • the auxiliary lever 34 is connected to the pivot lever 36 via a pivot axis 40 and carries the pressure roller 32 at one end and interacts with an inductive transmitter (sensor) 42 at its other end.
  • the pressure roller 32 is resiliently mounted on the auxiliary lever, so that the pressure on the winding can be adjusted.
  • a horizontally movable guide carriage 44 is provided on the carrier axis side facing the guide drum 12, which is driven by a spindle drive 46 parallel on both sides and an associated motor 48.
  • a transport lever 52 driven by a cylinder 50. The guide carriage 44 effects the drive axis propulsion, and the transport lever 52 causes the fully wound support axis to be carried out from position D to position E.
  • the transport lever is provided with holding rollers 54 arranged on opposite sides.
  • the carriage 44 has a transport roller 56 on the left side of the carrier axis in the drawings.
  • the transport lever 52 is pivotally mounted about a pivot axis 58.
  • the swivel arm 20 is provided in its lower region with a toothed segment 60 which is connected to a drive pinion 62.
  • the carrier axis in the operating position can be coupled with its own drive, so that the drive does not have to take place on the circumference of the winding.
  • a membrane cylinder 64 is arranged on the swivel lever 36 at the level of the pressure roller 32, which ensures a pneumatically sensitive pressing of the pressure roller on the winding.
  • the surface of the guide drum 12 is preferably roughened and thus prevents axial displacements of the web, since the guide drum 12 ensures the precise insertion of the web P between the pressure roller 32 and the winding 14.
  • the fully wound carrier axis lies, guided between the guide carriage 44 and the transport lever 52 at point D.
  • the carrier axis is still coupled to the winding drive, and the pressure roller 32 lies against the winding.
  • the inductive displacement sensor 42 controls the actuator 48. The greater the deviation from the target position, the higher the speed of the actuator.
  • An empty carrier axis 26 is already in the fork 22 of the swivel arm 20 and is ready for a transfer operation.
  • the swiveling process of the swivel arm 20 is carried out in order to transfer an empty carrier axis 26 from the receiving position A to the operating position B. Due to the slightly eccentric arrangement of the axes 16 and 18, the peripheral surface of the empty carrier axis reaches the periphery of the guide drum 12 and is driven by it. Then the drive of the wound carrier axis is braked in the position D, so that a loop is blown between the guide drum 12 and the finished winding 14 and the paper web is severed in this area, with the result that the leading end of the paper web P about the empty carrier axis 26 is laid and wrapped.
  • the pressure roller 32 is then in the pivoted-away state, as shown by dash-dotted lines in the figure.
  • the carrier axis with the winding 14 at point D is braked and the drive disengaged.
  • the guide carriage 44 and the winding drive move together from position D to B, and the finished winding is pushed out from D to E by means of the transport lever 52.
  • the transport lever 52 is then pivoted back empty from E to B.
  • the new carrier axis swivels to B, driven by the system on the guide drum.
  • the guide carriage 44 lies together with the winding drive at point B to the carrier axis 26, wherein the transport lever 52 presses the carrier axis against the guide carriage 44.
  • the winding drive then accelerates to the synchronous speed and is coupled.
  • the pressure roller 32 is placed on the winding and swivels into the operating position, while the carrier axis is simultaneously transferred by the actuator together with the winding drive to position C, which is the initial operating position.
  • the guide carriage 44 is then driven synchronously and thus the winding 14 is synchronously transported further with the associated carrier axis 26.

Abstract

Un dispositif d'enroulement en continu d'une bande, notamment d'une bande de papier, sur un axe porteur entraîné par un moteur, peut continuer à fonctionner même pendant le remplacement de l'axe porteur. Le tambour porteur est utilisé pendant le remplacement des axes de support de l'axe porteur vide à monter et sert de tambour de guidage (12) de la bande (P). Ce tambour est toujours maintenu à une certaine distance par rapport à la bobine (14). Un rouleau de serrage (32) presse la bande sur la bobine. Un signal de réglage de l'entraînement (48) du dispositif (44) de transport de la bobine est dérivé de la position du rouleau de serrage (32), qui se modifie à mesure que la bobine se remplit.
