Definitions

  • the present invention relates to a device for applying adhesive to book blocks or the like, in particular for applying adhesive to the book block back, according to the preamble of claim 1.
  • Adhesive application devices of the type mentioned are also known as Walzenleimwerke.
  • Page 284 f shows such a gluing plant schematically. It has two successively arranged, immersed in an adhesive tank application rollers, which roll through the block conveying direction concurrent rotation on the book block back while transferring the adhesive to the back.
  • the respective applicator roll is assigned to the roll thickness adjustable squeegee for metering the order thickness.
  • the adhesive application length can be varied by actuating the doctor blade by controlling the doctor blade between a zero application position for scraping and the adjustable application position.
  • DE 197 14 598 A1 discloses an adhesive application device for back adhesive strips with narrow side scrapes which can be adjusted separately from a main scraper and which are arranged upstream immediately upstream of a main scraper which can be adjusted with respect to an application thickness.
  • the soschabem is on the applicator roll produces reduced application of adhesive to the main scraper, so that different application strengths are formed on the applicator roll with the subsequent action of the main scraper.
  • the generation of a defined adhesive application length is effected by appropriate control of the main doctor.
  • the present invention has for its object to provide a device for applying adhesive to book block or the like., In particular for adhesive application to the book block back, according to the preamble of claim 1, which allows for high clock rates an exact and uniformly strong adhesive application and through a relatively simple and inexpensive construction distinguishes.
  • the idea of the invention is to place the adhesive coat thickness and adhesive application length functions in two separate doctor blades, with a setting device for the first (metering) doctor blade and a separate control device for the second (on / off) doctor blade. Characterized that in the order position, the distance of the on / off squeegee to the applicator roll is greater than that of the dosing doctor blade, the adhesive force is determined solely by the dosing doctor. A spring element in the control device of the on / off squeegee is not required, whereby the squeegee is much stiffer and their movement is superimposed by substantially less vibration.
  • the on / off squeegee has a fixed stroke.
  • Simple actuators such as solenoid, pneumatic cylinder and the like., Can be used to generate this digital control movement.
  • a simple cam gear is used, wherein the stroke of the on / off squeegee is firmly impressed in the control cam and the cam roller remains in constant contact with the curve.
  • this stroke is about twice as large or larger than the maximum distance to be set in the metering doctor.
  • the metering blade is arranged upstream and the on / off blade of the metering blade is arranged downstream.
  • a preferred embodiment of the invention provides that the effective doctor blade edges of the two doctor blade a small distance from Have a few millimeters to each other, so that immediately after opening the on / off squeegee determined by the dosing doctor job thickness is formed on the applicator roll.
  • the adhesive scraped off by the on / off doctor blade without forming encrustations, flows back away from the applicator roll into the adhesive basin.
  • an enlarged clearance is formed away from the doctor blade edges between the doctor blades and the upstream doctor blade has a small extent in the radial direction of the applicator roller.
  • the roller gluing unit 1 for applying an adhesive 4 to the back of a book block 2 is located under a transport device in which the book blocks 2, clamped by block clamps 3, with downwardly facing back and in a defined mutual distance continuously in the direction of arrow over the Walzenleimwerk 1 away be guided.
  • the roll sizing unit 1 consists essentially of an adhesive tank 5 for storing the adhesive 4 and a co-rotating to the block conveying direction and partially immersed in the adhesive tank 5 applicator roll 6, which transfers the recorded adhesive 4 by rolling on the book block 2 on the back.
  • the sizing unit 1 has two separate squeegees 7, 8, a first metering squeegee 7, adjustable in the distance from the application roller 6, for metering the application thickness and a second, controllable on / off squeegee 8 for producing a defined adhesive application length.
  • the metering blade 7 is disposed upstream of the on / off squeegee 8. It is fastened to holders 13, which are guided linearly via guide shafts 16 in guide blocks 17. About an in grooves of the holder 13 cross and mounted in bearing blocks 15 eccentric shaft 14, the position of the Dosierrakel 7 and thus a certain order strength adjustable.
  • the adjustment V A of the job thickness is effected by rotation of the eccentric shaft 14, which is shown symbolically in FIG. 2 by the dashed double arrow.
  • side scraper 7 a are formed at the ends of the metering doctor.
  • the on / off squeegee 8 At the other end of the double lever lever cam lever 10 is the on / off squeegee 8. It is attached via a block 9 to a boom of the cam lever 10.
  • the control curve consists of two adjacent control cams 12 a, b, wherein by rotation of the two cams to each other sets a change in the order length. The rotation can be done at standstill by hand or with the drive running via a superposition gear.
  • the stroke of the on / off squeegee 8 is dimensioned such that their distance in the order position is approximately equal to twice the distance of the metering blade 7, whereby in the order position, the application rate is determined solely by the metering blade 7. As stated above, resulting from the increased distance fast switching times for switching on and off of the adhesive application.
  • simple drive elements generating a digital control movement such as a lifting magnet, pneumatic cylinder and the like, can be used for controlling the on / off squeegee 8.
  • the effective doctor blade edges of the two doctor blades 7, 8 have a small distance of a few millimeters to each other.
