Definitions

  • the invention relates to a device for separating and again Creation of an incoming material web on winding machines on a winding tube, which is driven by a rotating shaft is, the incoming material web by means of a deflection roller partially wrapped by the material web is pressed against the winding tube and the running material web after leaving the winding tube by means of a the path of the material web movable and through an energy store drivable forth extending to the course of the path Cutting knife and the new path start with a firmly connected with the cutting knife across the web extending brush is applied, the separating knife accelerated compared to the running material web becomes that its speed is greater than the running speed the material web.
  • the cutting knife is opened held on both sides by guide bands, which over rotatable pulleys run and being an electric motor over an axis drives a flywheel, which is flanged over a Coupling the associated roles in accelerated Offset and the guide belts Cutting knife on the cutting point in accelerated motion feeds.
  • a corresponding device is described in DE-OS 22 32 338, the separating element with a pneumatic or hydraulic drive via a rack and a toothed segment is driven, the running path between empty Separates the winding tube and a deflecting element, the separating element is pivoted coaxially to the winding tube and then an air box connected to the separating element presses the beginning of the web against the winding tube.
  • the Cut separators on the winding tube and special Require winding cores with cutting grooves on the core Here however occur through the cutting process over time Core damage along with the grooves in the core Cause deformations in the material web in the winding.
  • the invention was based on the object of a device to create the generic type mentioned above, which Reliable cutting even at high web speeds a running material web and a crease-free application of the new start of the path on the winding tube and in particular also for driving the cutting knife and the brushes required aggregates compared to the above State of the art as wear-free as possible with a minimum of moving parts and light weight of these parts work.
  • the device according to the invention is based on the example of a so-called Wendewicklers explained in more detail, the invention however, in no way limited to this special winding device is, but to all possible from the state of the Technology known winding and separating devices applicable is.
  • Figure 1 shows the separation and application device at the moment of the separation process.
  • a preferably coated web (1) runs over a deflection roller (2), a so-called outer one Contact roller (3) on the winding tube (4) and wraps around about a quarter of their size.
  • After leaving the web is the winding tube over further deflection rollers (5, 6, 7) wound on a further winding tube (8).
  • the entire device is rotatable in the direction of the arrow with the Pivot point (11).
  • the cylinder (22) can be pivoted in via a lever (23) Separating and applying device (9) to be described in more detail.
  • the desired diameter is on the winding tube (8) of the winding (24) is reached, the separation and application device (9) swung in, the material web (1), as is further described in more detail below, approximately at the Where she leaves the still empty winding tube (4), across separated and by means of a firmly connected to the cutting knife Applying brush to the winding tube (4) so that the newly created beginning of the web wound on this winding tube becomes.
  • the remaining web is wound on the winding tube (8), this winding tube is braked, the full one The winding is removed and a new one is placed on the winding axis Empty winding sleeve (not shown) placed.
  • the separation and application device (9) again pivoted so that it is in the position as indicated in Figure 2 remains.
  • the inner contact roller (10) is pivoted about the pivot point (21), that they are indicated as the inner contact roller as in Figure 2 lies against the circumference of the winding tube (4) and so smooth winding of the web favors.
  • the knife (12) for cross cutting the web is rotatable Shaft (16) firmly connected.
  • the length of the knife is slightly larger than the width of the material web (1).
  • the shaft is over lever (15) with the knife (12) connected via a fastening device (26), the knife at a certain angle to the material web (1) is aligned. This angle is preferably approximately 90 °.
  • the contact brush (13) which has a slightly larger radius than the knife (12) describes.
  • the shaft (16) with the knife (12) rotates in the direction of the arrow in the same direction as the direction of web travel; is the peripheral speed of the knife (12) greater than the web speed of the material web (1), they is at least 1.5 times. This overtakes the separating and Application device during the rotation of the shaft the material web, so that the contact brush the material web on the Can touch the surface of the winding tube (4).
  • Like the figure 4 shows the ratio of the radii of knife (12) and brush (13) and their respective distance from the winding tube (4) dimensioned so that the free end of the knife is straight is still spaced from the surface of the winding tube (4) and the free end of the contact brush the new one Start of web at an angle between 40 ° and 90 ° at the Specifies the winding tube.
  • the brush is lying in the moment of cross cutting on the material web at about the point where it leaves the winding tube.
  • the surface of the winding tube cannot be closer by means of a shown spray device (27) with glue or water can be applied to make it easier to glue the web.
  • the winding tube (4) to be made from a plastic material with adhesive adhesion.
  • the shaft (16) with the knife (12) is through a hydraulic torque booster (17) with which it is directly connected.
  • Motor and shaft are direct, So without coupling links, connected to each other, for example by pressing appropriately shaped conical Parts of motor shaft and shaft (16) or by others Measures known from the prior art.
  • the wave (16) is mounted on both sides (28, 29).
  • the hydraulic motor operates at an operating pressure of around 160 bar operated, the hydraulic motor is controlled by an electric stepper motor (corresponds to 1000 steps 360 °). Manufacturers of such engines are, for example SIG (Swiss Industry Company).
  • the whole The arrangement of the motor shaft knife is designed to be low-mass, among other things by using light metal for shaft and Lever that the cutting knife, as shown in Figure 5, for Reaching the full speed only by an angle of is rotated about 130 °, then this speed becomes about maintained for a rotation angle of 130 °, while during the separation process takes place at this time, and then the knife speed again over an angle of about 90 ° decelerated to zero.
  • the separating device (9) is pivoted and during this time the swivel arm will slowly return to its original position, for example by a fork light barrier is marked, turned back so that the separating and Application device prepared for the next separation process is.
  • Knife (12) To compensate for the enormous acceleration forces caused by the Knife sits on the shaft (16) also via the levers (15) connected a balance shaft (18) opposite the Knife (12).
  • This shaft (18) serves as a counterweight to Knife (12) and can by intermediate washers (19) arranged adjacent a connecting arm to the shaft (18) are balanced so that during the rotation of the Knife the shaft (16) is not deformed and thus that Knife (12) a linear section through the material web accomplished.
