Definitions

  • the present invention relates to a method for rubbing a book cover on the glued outer surfaces of a book block according to the features of the preamble of claim 1 and an apparatus having the features of the preamble of claim 5 for carrying out the method.
  • Hanging machines or book streets are known. These have a oriented in a vertical plane conveyor in the manner of a continuously rotating paternoster with saddle plates as transport elements.
  • a book block is opened in the middle with the back up pointing astride one of these saddle plates pushed and transported by this in a first conveyor section.
  • the book block is guided along a gluing unit with applicator rollers arranged on both sides of the transport path, the applicator rollers applying the adhesive to the outer surfaces of the book block, which are usually formed by so-called attachments.
  • this gluing unit there is a support plane formed of bars, on each of which a book cover is provided with the outside pointing upwards and aligned with its back region to the book block back.
  • the book block glued to the side surfaces plunges with its back into the back area of the book cover and lifts it from its provision position, wherein the cover of the book cover at the back region starting at the side surfaces of the book block fold.
  • a grater with a pair of gripping rollers.
  • the grater is vertically movable and comprises such a drive that it moves vertically starting in a lower starting position and thereby synchronized in a section with the fifth wheels of the circulating conveyor the back region of the Book cover supports before reversing its direction of movement in an upper end position.
  • the Anreibewalzen roll on the outer surfaces of the book cover, while rubbing it against the book block and finally reach their lower starting position.
  • the Anreibewalzen are stored horizontally positioned in the grinder.
  • the adjustment is carried out via spindles symmetrical to the plane spanned by the fifth wheel plates of the circulating conveyor plane.
  • a controllable drive of this thickness adjustment allows automated setup. Without operator intervention, the selected thickness setting is maintained throughout the production. Since the book thickness can vary slightly from book to book as well as within a book, the Anreibewalzen are spring-loaded, whereby damage to the grater when misadjustment can be avoided.
  • the gripping force is determined by the spring rate and the degree of deflection. Since the variations in thickness actually occurring during the grinding are not exactly predictable, the acting rubbing force is only exactly known on average.
  • the object of the present invention is therefore to provide a method and a device for the grinding of a book cover on the glued outer surfaces of a book block available, which are exempt from the disadvantages mentioned.
  • the invention provides a method according to the characterizing features of claim 1 and a device according to the characterizing features of claim 5.
  • the features of the dependent claims describe advantageous embodiments of the invention.
  • the known feed motion of the feed rollers is regulated, wherein different control variables are used in different sections of the vertical movement of the grinder.
  • the feed movement of the Anreibewalzen is position-controlled, so that the horizontal position of the Anreibewalzen, i. the position regarding the book thickness controlled variable.
  • the gripping rollers can be positioned so accurately that the back portion of the book cover, as long as it is between them, positioned in the lateral direction exactly to the book block back and during the synchronized to the movement of the saddle plates upward movement of the grater is performed. A breaking of the reinforced by a Schränz back portion of the book cover from this guided position can be prevented.
  • the feeding device of the Anreibewalzen includes as feedback a sensor system for determining the current horizontal position of the Anreibewalzen, which is connected via a corresponding data line to the same control of the device, which also controls the adjustment of the feed device.
  • the required encoder can be integrated in the adjustment itself.
  • the feed movement of the gripping rollers is controlled by controlled force is used as a control variable applied by the gripping rollers on the book force. In this way, the force exerted during the grinding can be predetermined and precisely maintained.
  • the feed device as feedback comprises a sensor system for determining the momentarily acting on the Anreibewalzen reaction force, which is connected via a corresponding data line with the mentioned control of the device.
  • a sensor system and the adjustment itself can be used, so that no additional encoder is required.
  • the change takes place between position control of the feed device on the one hand and its force control on the other hand and vice versa based on the relative position of the Anreibewalzen to the respective fifth wheel plate in the vertical direction and / or their temporal change.
  • the circulation conveyor is equipped with a transmitter, in a particularly simple manner a rotary encoder, which is connected to the adjusting drive of the delivery device-driving control.
  • the position control and / or the force control of the feed movement takes place on the basis of desired value curves, so that a non-uniform course of the feed movement is made possible. In this way, vibrations in the feed movement and, in particular, in the case of the laterally projecting back region of the book cover, a hard impact of the feed rollers on the book covers can be avoided.
  • the drive of the feed device by a servo motor which is suitable for both a position control and for a force control, so that the actuator does not need to be divided into two differently operating systems needs.
  • servomotors provide their control units with data that can be interpreted as a position, as well as those that can be interpreted as moment or force, so that separate encoders can be dispensed with. In this way, the drive of the delivery device can be kept extremely compact.
  • the equipment of the grinder with a delivery device with its own drive and its own control loop per Anreibewalze is particularly advantageous.
  • the grater also intended asymmetric hooking or one-sided rubbing.
  • the block next to pages of paper also contain covers for digital data carriers, whereby the focus of the block is outside its center plane and the block advantageous in Area of the center of gravity instead of the geometric center of the fifth wheel plate is worn to avoid lateral slippage.
  • FIG. 1 shows schematically a device for hanging books with a working according to the principle of a paternoster circulation conveyor 23, the fifth wheel plates 9 are continuously moved by a common traction means in a vertical plane without changing their spatial orientation in a transport direction d.
  • the previously supplied to the circulation conveyor 23, opened in the region of its center of gravity book block 1 is astride detected by a fifth wheel plate 9.
  • the in Fig. 1 Book block 1 has almost completely passed through the gluing unit 24 and emerges with its back 2 straight into the back area of the book cover 5 which has been stretched out and aligned on a support 22. Above this support 22 is a pair of gripping rollers 10 a trimmer.
  • the book cover 5 is raised by the book block back 2 from its provision position on the support 22, so that the cover book cover 6 completely abut the glued side surfaces 3 of the book block 1. Meanwhile, the rubbing device moves synchronously with the saddle plate 9, so that the back portion of the book cover 5 is held and guided in alignment by the rubbing rollers positioned on both sides.
  • the grater as in Fig. 3 shown constructed in a frame 11 which is mounted vertically movable on a bearing mounted in the machine frame not shown guide column 12 and secured by also not shown guide surfaces rolling rollers 13 against rotation about the guide column 12.
  • the Movement of the grinder along this guide column 12 is generated by a drive, not shown, which is designed in a familiar to the expert.
  • Both gripping rollers 10 are adjustable by a correction device 20 in its vertical position to the frame 11 and also to each other.
  • a correction device 20 in its vertical position to the frame 11 and also to each other.
  • the position of the Anreibewalzen 10 can be corrected to the back region of the book cover 5 during the synchronous movement section.
  • manufacturing tolerances of the device as well as in the production of the book blocks 1 and the book covers 5 occurring systemic shape errors of the back areas can be compensated.
  • the Anreibewalzen 10 are mounted on linear guides 14 in a horizontal plane at a distance movable, and their feed motion b via a feed device 21 from the linear guides 14 parallel spindle drives 15.
  • Linear guide 14 and spindle drive 15 are each on both sides of each Anreibewalze 10, wherein the same Anreibewalze 10 associated spindle drives 15 are operated synchronously via a drive connection 16.
  • the feed device 21 is driven by an electric motor 19.
  • a servo motor is used, which forms a control loop with the controller 26 of the device, which is closed by data lines 25.
  • the data transmitted by the motor 19 to the controller 26 includes information interpreted by the controller 26 as the instantaneous position of the gripper rollers 10 with respect to their feed motion b and as applied by the Anreibewalzen 10 on the book cover 5 rubbing force and so as actual values for the control the delivery movement b are used.
  • Each dressing roller 10 is assigned its own feed device 21, each with its own drive and control circuit, in order to allow in a particularly simple manner an off-center transport through the saddle plates 9 in asymmetric products.
  • a combination of a position-adjustable first and a force-controllable second drive can be used as the drive of the feed device, such as, for example, a simple electric motor positioning drive superimposed with a pneumatic cylinder.
  • a simple electric motor positioning drive superimposed with a pneumatic cylinder.
  • Such a drive combination can be constructed event-controlled and therefore requires a less complex control 26, as required by the use of substantially variable usable servomotors 19.
  • FIG. 2 An exemplary sequence of motion of the Anreibewalzen 10 is in Fig. 2 shown schematically.

  • the in the in Fig. 2 shown left Anreibewalze 10 arrows show the direction of the feed movement b of the gripper roller, each of which runs horizontally to the fifth wheel plate 9 pointing, and Anreibefar a the grater, which is the transport movement d counter-directed vertically downwards.
  • Anreibewalze 10 shown extending their trajectory c is shown relative to the book block 1. This can be broken down into the gripping movement a and the infeed movement b .
  • the movement path is subdivided into areas A, B in which the feed movement b of the gripping rollers 10 is alternately position-regulated and force-controlled.
  • Section A indicates the area with the delivery position as a control variable, which in turn can be subdivided into sections with constant setpoint input A 2 , A 5 and transition areas A 1, A 3 , A 4 , where changes in the setpoint occur.
  • Section B shows the force-controlled region of the movement path c of the Anreibewalze 10, in which changes in the delivery position occur only with changes in the cross section or the rigidity of the book, as long as the target value is kept constant.
