Definitions

  • the invention relates to a device for the peripheral drive of a winding roll made of sheet material according to the preamble of patent claim 1.
  • the invention has for its object a device for the peripheral drive of a winding roll made of web-like material, especially in unwinding devices of rotary printing presses, with a drive belt pivotable by a working cylinder articulated on the frame via a belt arm mounted in the frame, on the pivot axis of which a driven one and on the other end of which is arranged on a pivotally connected to the belt arm coupling a non-driven belt reel, so that with low technical means both the contact pressure of the drive belt on the winding roller and its pretension in the running direction can be regulated according to the required operating conditions.
  • the push rod of the working cylinder is connected in an articulated manner to the belt arm via a coupling and this coupling is movably supported against the coupling carrying the belt roller via a rocker.
  • the gearbox equipped according to the invention enables the use of only one working cylinder for regulating the contact pressure of the drive belt and its pretension in the direction of travel, an optimal relation between the two force components which can be achieved by appropriately dimensioning the gearbox remaining largely constant.
  • the simple, unrestricted the individual operating conditions such as. B. sudden braking of the winding roll during an emergency stop, acceleration of a new winding roll for the gluing process and maintenance of the web tension during the normal processing process, adequate controllability through the use of only one working cylinder is particularly noticeable.
  • various transmission elements can also be constructed in several parts, e.g. B. are each formed as a pair of elements. This applies in particular to the belt arm. Also, without changing the solution principle, further belt rollers supporting the drive belt can be arranged in its running direction.
  • a tension spring which is connected to the belt arm and which is connected to the push rod of the working cylinder, counteracts a slackening of the drive belt in its position raised from the winding roller.
  • the tension spring is dimensioned so that its spring force merely prevents the belt roller arranged on the coupling from swiveling inwards when the drive belt is lifted from the winding roller and thus prevents its sags on the winding roller and only appears slightly to regulate the pretensioning of the drive belt during operation .
  • a stop limiting the pivoting movement of the coupling articulated to the push rod of the working cylinder is connected to the belt arm.
  • the gear for the pivoting of the drive belt 3 consists of a pivotally mounted in the frame 4, double-sided via separate connections 5; 6 with a pressure medium can be acted upon by a working cylinder 7, which is connected in an articulated manner via a coupling 8 to a belt arm 9 pivotably mounted in the frame 4.
  • a belt pulley 13 for the drive belt 3 which is driven by a motor 11 fastened to the frame 4 via a toothed belt 12, is mounted.
  • a further coupling 16 which supports itself via a rocker 14 against the coupling 8 connected to the push rod 15 of the working cylinder 7, articulates, on the opposite end of which a further belt reel 17 for the drive belt 3 is mounted.
  • a tension spring 18 connected to the belt arm 9 engages the coupling 8 connected to the push rod 15 of the working cylinder 7.
  • a stop 20 fixed to the frame limits the swiveling of the belt arm 9 upward from the winding roll 1.
  • each operating state occurring such as e.g. B. a stop braking or acceleration of the winding roll 1 can be regulated to the required extent with little technical effort.

Claims (4)

  1. Dispositif pour entraîner, au niveau de sa périphérie, un rouleau d'enroulement (1) formé d'un matériau en forme de bande, notamment dans des dispositifs de déroulement de presses rotatives à imprimer, comportant une courroie d'entraînement (3), que peut faire basculer un vérin de travail (7), qui est articulé sur le châssis (4), par l'intermédiaire d'un bras porte-courroie (9), et dans lequel un galet de circulation de courroie entraîné (17) peut être disposé sur l'axe de basculement (10), qui est disposé dans le châssis (4), dudit bras porte-courroie, tandis qu'un autre galet de circulation de courroie non entraîné (17) est disposé sur l'autre extrémité dudit bras, sur une bielle (16) reliée de manière à pouvoir basculer au bras porte-courroie (9), caractérisé en ce que la tige de poussée (15) du vérin de travail (7) est relié de façon articulée par l'intermédiaire d'une bielle (8) au bras porte-courroie (9) et que cette bielle (8) prend appui, de manière à être déplaçable au moyen d'un bras basculant (14), contre la bielle (16) portant le galet de circulation de courroie (17).
  2. Dispositif selon la revendication 1, caractérisé en ce qu'un ressort de traction (18), qui est relié au bras porte-courroie (9), d'un dispositif de tension de la courroie d'entraînement (3) attaque la bielle (8) reliée à la tige de poussée (15) du vérin de travail (7), en s'opposant à une détente de la courroie d'entraînement (3), dans sa position dans laquelle elle est écartée du rouleau d'enroulement (1).
  3. Dispositif selon la revendication 1, caractérisé en ce qu'au bras porte-courroie (9) est reliée une butée (19) qui limite le mouvement de basculement de la bielle (8), articulée à la tige de poussée (15) du vérin de travail (7), dans la direction de ce vérin.
  4. Dispositif selon la revendication 1, caractérisé en ce qu'une butée (20), qui limite l'écartement du bras porte-courroie (9) par basculement à partir du rouleau d'enroulement (1), est reliée au châssis (4).
