Definitions

  • the invention relates to a method for precise alignment of a product to be stapled with respect to a stapling device in a saddle stitcher and a suitably designed saddle stitcher.
  • Saddle stitchers are paper-processing machines with which a product, for example a booklet, is assembled and stapled from several folded sheets.
  • a product for example a booklet
  • printed folded sheets of stacks are occasionally fed, opened and placed on a gathering chain.
  • the stapled number of signatures is collected and aligned on the gathering chain by drivers.
  • the gathering chain transports the collected signatures to a stapler where stapling heads staple them with staples.
  • trimmer is usually provided after ejection, from which the end products are transported to a display on.
  • Saddle stitchers are divided into two types of stapling: stapling at a standstill and stapling in motion.
  • the stapler consisting of stitching carriage and Hefthub issued, with the stapled product must be moved and at least temporarily adjusted to its movement.
  • the vote of the movement of the stapler is carried out to move the gathering chain that transports the product to be stapled.
  • the position of the product is determined by the nature of the gathering chain, in particular by the nature of the driver of the gathering chain. Deviations occur in this type of stapling the actual clamp position from the desired clamp position, the deviation may vary from product to product.
  • the deviation of the staple position results inter alia from the fact that the movement of the stapling device is matched to the movement of the gathering chain and it is assumed that the product to be stapled is accurately guided by the collecting chain.
  • the saddle stitcher for folded sheets disclosed therein has a stitching station and at least one folded sheet feeder, a gathering chain and a drive.
  • the drive consists of individual drive units, one of each of the stitching station, each folded sheet feeder and the gathering chain is assigned, each individual drive unit has at least one electric motor and a control unit associated therewith. Furthermore, a connection for exchanging data and / or control signals between the control units is provided.
  • a saddle stitcher has at least two separate drives for the stapler and for the saddle chain. Furthermore, there is a sensor for detecting the position of the product to be stapled in an advantageous manner in the running direction of the gathering chain immediately in front of the stapler. With this sensor will The actual position of the product in the running direction is exactly recorded and compared in an evaluation unit with the expected position of the product. A positional deviation determined in this case is supplied to the drive unit via a control unit as a controlled variable. In the drive unit, the drive of the gathering chain and / or the drive of the stapling device is controlled so that the determined at the time of measurement position deviation of the product is compensated until the beginning of the stapling process for this product. This means that the actual position and the target position of the product match. As a result, the clip is formed exactly at the predetermined location of the product.
  • the compensating movement is reversed again until the next machine cycle or taken into account in the compensating movement for the next product accordingly. This ensures that the position of the staple of the subsequent product is not affected.
  • FIG. 1 A representative example of a saddle stitcher according to the invention is described in FIG. 1 shown.
  • a drive motor M1 drives by means of a crank 1 and the connecting rod 2 to the stapling carriage 3, which is mounted on a straight line 4.
  • the drive motor M2 is provided for the gathering chain.
  • the toothed belt wheel 9 By means of the toothed belt 10, the toothed belt wheel 11 and the sprocket 12, the gathering chain 13 is driven. It is envisaged to control these two motors M1 and M2 such that the Movements of the stitching carriage B1 and the collecting chain B2, which in the Figures 2 and 3 are shown, can be coordinated.
  • the motion is adjusted in such a way that a sensor 14 is provided for detecting the position of the product to be stapled.
  • this sensor 14 is located in the running direction of the gathering chain immediately in front of the stapler. Through this sensor, it is now possible to accurately detect the actual position of the product in the running direction.
  • the determined values are forwarded to an evaluation unit (not shown) and compared therewith to the expected position of the product.
  • a positional deviation determined in this comparison is fed to the drive unit via a control unit, not shown, as a controlled variable.
  • This controlled variable it is now possible to control the drive of the gathering chain and / or the drive of the stapler so that a possibly determined at the time of measurement position deviation of the product is compensated until the beginning of the stapling process for this product.
  • This regulation ensures that the clamp is always set exactly to the predetermined position of the product.
  • FIG. 2 the essential elements of the drive of the stitching carriage B1 are shown.
  • the motor M1 drives the crank 1, which realizes, by means of the connecting rod 2, the horizontal movement of the stitching carriage 3 along the sliding straight line 4.
  • the drive motor M1 moves a crank which is concealed in this view and which, with the connecting rod 6, realizes the horizontal movement of the sword carriage 7 along the sliding straight line 8.
  • FIG. 3 the drive of the collecting chain B2 is shown.
  • the motor M2 moves a toothed belt wheel 9, which transmits the rotary motion to the toothed belt wheel 11 by means of the toothed belt 10.
  • the downstream sprocket 12 thus the gathering chain 13 is driven.
