Definitions
- the present invention relates to a device for separating a Material web with one of the material web adjacent rotatably mounted Carrier, the transversely to the direction of the web with a predetermined Distance to the material web is arranged, and one on the carrier arranged separating element.
- a device for separating a material web is necessary, for example, in order to produce smaller roll units in the production of continuous webs of the web-shaped material, which is then further processed and can be transported. Also become separation devices used in order to prevent production faults undamaged parts of the material web to separate from faulty locations of the material web.
- From DE 195 29 581 C2 is a device for cross cutting a running Material web known.
- a serrated knife that goes against the Web direction in the web or in the web direction in the web is retracted, under a strong angle of inclination of maximum 45 ° pivoted into the material web.
- DE 692 03 913 T2 discloses a device for separating a material web described, equipped with a pair of perforating rollers is.
- a knife or one or more counter knife used to generate transverse perforations in the material web .
- the perforations define tear lines of the web, through the interaction cut by separating means on a main roll and a separating cylinder transversely become.
- the material webs By increasing production speeds with running speeds the material webs, for example, of 2,000 m / min, be increased demands on the separation of a material web made. required is the separation of a material web without slowing down or even stopping the material web. Ideally, the web is added Production speeds separated, so that production by the Disconnecting is not affected. In consequence of the high running speeds The material webs are short reaction times and high speeds of movement the separating elements required. The separation process must happen so fast that the running web during the Do not accumulate separation process behind the separator.
- the invention is based on the problem of interference when disconnecting to reduce running material webs.
- the contact surface of the Acceleration element has a frictional contact with the material web.
- the accelerating element has an increasing Radius at least on a partial circumference of the carrier.
- the friction force increases with increasing radius.
- the separating element which together with the Carrier to a high speed with the help of the accelerator element is brought. Due to the increasing radius the acceleration element is the frictional contact to the material web first low and then continues to grow. Due to this increase in Frictional action is not abruptly intervened on the web, which is advantageous to avoid interference possibilities.
- the wearer may already be at its circumference have an increasing radius, so that the carrier the function of the acceleration element with takes over, without a separate Acceleration element is attached to this.
- the separating element has interruptions on. With wide material webs can over the length the carrier may require several bearings, thus sagging the wearer is avoided. At the interruptions of the Separating element can thus attack bearing elements that the carrier support.
- the device according to the invention has a drive on the carrier.
- the drive can be a movement of the wearer be initiated.
- An embodiment of the invention provides that the carrier by the Drive is rotationally movable. This allows the acceleration element also engage with the web as soon as the increasing Radius of the acceleration element touches the web.
- the carrier is brakable.
- the carrier is after a radial or rotational movement can be brought into its initial position. Further cutting through subsequent sections of the material web is thus avoided.
- the carrier is braked by means of the drive.
- One Electric braking has the advantage that mechanical wear is avoided becomes.
- mechanical Rotational energy is converted back into electrical energy become.
- a mechanical brakes or a combination of electric braking and mechanical braking respectively.
- the carrier designed as a tube.
- a tube is a body of revolution that serves as a carrier is particularly suitable because this has a lower moment of inertia compared to a massive cylinder.
- a small one Weight of the carrier advantageous for the acceleration process.
- a further embodiment provides a displacement device, with which the material web is movable to the acceleration element.
- the contact surface of the accelerating element can engage with the web.
- the Displacement device can be on existing guide elements be attached to the web, so that a short-term lowering and subsequent lifting or vice versa can be realized. Also a separate displacement device is one way to move the material web in the direction of accelerating element.
- At least one counter-holder is on the separating element arranged opposite side of the web.
- the backstops are rotatably mounted and can the running speed of the material web to follow synchronously as a rotational movement.
- the counterholds can, for example be designed as a cylinder, pipe or roller. The backstops act during the separation process to avoid the material web counteracted, caused by the force of the accelerator element and the separating element.
- the material web tensioned and is smoothable Due to the increasing radius of the acceleration element and the counterforce of the backstop, the web is stretched and smoothed at the same time, so that optimal for the separation process Conditions exist.
- a carrier 1 On the circumference of a carrier 1, designed here as a tube, is an acceleration element 2, which encloses a partial circumference of the carrier 1 and having an increasing radius.
- a separating element 3 In the place of the largest Radius of the acceleration element 2 is a separating element 3, which is a knife, for example.
- the carrier 1 with the acceleration element 2 and the separating element 3 is rotatably mounted and arranged at a certain distance from a material web 4.
- two Counterholder 5 On the opposite side of the web 4 are two Counterholder 5. In further embodiments, more or even less counter-holders are used.
- a first possibility is that with a drive 6 a rotational movement of the carrier 1 is initiated. Due to the increasing radius of the Acceleration element 2, the distance between the carrier 1 and web 4 is reduced and there is a contact between the accelerator element 2 and the web 4. From this point becomes due to the frictional contact, the acceleration element 2 through the web accelerated and this is also smoothed out and at the same time curious; excited. As soon as the separating element 3 hits the material web 4, becomes these separated.
- a second way to initiate the separation is that with the help of Drive 6 of the carrier 1 in a rectilinear movement to the material web 4 is moved. Once the acceleration element 2 with the material web 4 comes into contact, the carrier 1 by the frictional contact in Rotation offset and the separator 2 on the circumference of the carrier. 1 separates the web 4.
- the carrier 1 is possible, which is caused by the drive 6.
- the carrier 1 at a predetermined distance from the material web 4 are rotated by means of the drive 6 in rotation, without that the acceleration element 2 or the separating element 3 the Contact material web.
- the rotating support 1 by means of the drive 6 can be moved in the direction of the web, until between accelerator element 2 and web 4, a contact is made.
- the separation of the material web 4 takes place with the Separating element 3.
- the carrier 1 rotates before the frictional contact begins with an approximately same speed as the running speed the web 4. It is also intended that the time the first contact between acceleration element 2 and material web 4 is chosen so that the duration of the frictional contact possible takes a long time, i. that the contact at the smallest possible radius of the acceleration element 2 is used.
- Another way to initiate the separation is to apply a displacement device 7. This acts in at least one place the web 4 and moves the web 4 in the direction of the carrier 1.
- the carrier 1 is located between two lowering devices 7.
- the counter-holder 5 are corresponding carry along the movement of the web so that they continue strained and smoothed.
- to initiate the separation of the Material web further combinations of the mentioned possibilities conceivable. After separating the material web, the rotational movement the carrier 1 by means of the drive 6 or with an additional mechanical brake 8 are slowed down or stopped, that the subsequent web remains undamaged. A combination of Mechanical and electrical braking is also possible.
