Definitions

  • the invention relates to a bookbinding machine for back rounding of book blocks with a conveyor device that clamps the book block and with a back round device that acts on the book block after the book block has been released by the conveyor device, the conveyor device consisting of book block clamps that can be moved continuously in a closed orbit and the back round device synchronously with the book block clamps can be driven along a defined section of the orbit.
  • Such a bookbinding machine is known from FR-A-1439825.
  • the back-round device is formed by a counterpressure plate concave in the transverse direction and by a stamp above the counterpressure plate which is convexly shaped in the transverse direction in accordance with the front section of the book block.
  • a bookbinding machine can be found in US-A-1959656 with a round device operating according to the roll round principle and with a device for shaping the book block spines.
  • the book blocks are placed between two round rollers on a support under contact with a stop and are grasped by the round rollers. These act on the two sides of the book block to carry out the rounding process and at the same time convey the book block downwards after the edition has been removed.
  • the round rollers are automatically moved in the longitudinal direction on their bearing shafts and, after the book block has been picked up, are released again by the round rollers by clamping the pressing device in order to return to their starting position.
  • the object of the invention is seen in creating a bookbinding machine for the back rounding of book blocks of the generic type, with which a high-quality back rounding can be achieved at high working speed.
  • the object is achieved by the characterizing features of claim 1.
  • the bookbinding machine according to the invention offers the technical advantage of a substantial increase in working speed while achieving optimal round results.
  • the round rollers can be moved vertically in the recesses of the clamping jaws and the vertical movement is superimposed on the rotary movement of the round rollers in such a way that the vertical movement of the book block which is produced as a result of the rotary movement is compensated for, the outer sheets or printed sheets preferably being at a constant level being held.
  • the holding of the book block in the clamp of the book block transport system in a defined position caused by the compensation movement is important for the subsequent work process.
  • a further increase in the working speed can be achieved in that at least one further back rounding device is arranged in the bookbinding machine for the simultaneous back rounding of several book blocks.
  • the device for back rounding of book blocks 1 is, according to the invention, assigned to a book block transport system of a book binding machine with a multiplicity of book block clamps 2, which are located at the same mutual distance from one another, each with a pair of clamping jaws 3 and 4, which can be set at a variable distance from one another and which exert a contact pressure on the pages to apply a holding force exercise a book block 1 with your back facing down.
  • the inner clamping jaw 4 of the book block clamp 2 is fixed in place on a support frame 6 running in guides 5 of a machine frame, which is connected to a transport chain by means of a drive, and the outer clamping jaw 3 for the inner clamping jaw 4 via actuating means (not shown) in the sense of closing and opening for receiving or Release of a book block 1 can be moved in parallel.
  • the book block clamp 2 with the book blocks 1 held clamped are continuously driven along a closed orbit by the transport chain guided around deflection chain wheels.
  • the device for back rounding of book blocks is located essentially below the book block transport system and in a straight line section and is synchronized by a drive arrangement, the detailed description of which is provided elsewhere, with the continuously running book block clamps 2 along the movement path over a defined distance then moved back to the starting position, reversing their direction of movement.
  • Printed sheets by simultaneously rolling corrugated round rollers over a defined angle of rotation and under pressure, the sheets or printed sheets being increasingly advanced as the book block passes through the round rollers towards the center of the book block, thus giving the book block its desired rounded back shape and front cut shape.
  • recesses 3a, 4a are provided in the inner and outer clamping jaws 4, 3 according to the invention, through which the round rollers 7, 8 during their synchronous operation with the book block clamp 2 Book block pages are movable back and forth.
  • This transverse movement of the two round rollers must inevitably be timed to the opening and closing movement of the clamping jaws 3, 4 in such a way that the book block 1 is only released by the clamping jaws 3, 4 after being taken over by the round rollers 7, 8, whereupon immediately the rounding process begins by the rotating round rollers 7, 8 rolling on the sides of the book block 1.
  • the two round rollers 7, 8 are simultaneously lifted from their lower position into an upper position shown in dash-dotted lines in the recesses 3a, 4a of the clamping jaws 3, 4 with their rotational movement in the direction of the arrow, as a result of which the round rollers roll as a result 7, 8 on the sides of the book block 1 occurring downward vertical movement of the book block 1 is compensated and thus the fold edge on the edge of the book block in the book block clamp 2 is kept at a constant level.
  • the device for back-rounding book blocks 1, which is driven back and forth along the movement path of the book block clamps 2, has a frame 10 which is composed of a base plate 10a and a support plate 10b, which is movable on vertical guides 17 of the base plate 10a in the vertical plane.
  • Swivel levers 14, 15, in which the two round rollers 7, 8 are each freely rotatably supported at the ends, are received by the height-adjustable support plate 10b on both sides of the book block movement plane in a diametrical arrangement.
  • the vertical movement of the two round rollers 7, 8 in the recesses 3a, 4a of the clamping jaws 3, 4 and the simultaneous rotary movement of the two round rollers 7, 8 for executing the rounding process take place in time with the transverse movement towards the book block pages and with the continuously running one Book block clamp 2 is actuated from a common drive source, not shown, starting from a drive lever 20, through which parallel lever arrangements 21, again lying on both sides of the book block movement plane and connected to one another, are actuated.
  • the parallel lever arrangements each engage at two points on the support plate 10b which are at a distance from one another in order to move it, guided on vertical guides 17, between a lower and an upper end position.
  • the two round rollers 7, 8 perform a defined rotary movement to complete the rounding process on the book block, in that stationary racks 22 and 22a set the pinion 23 on the bearing shafts 13 in rotary motion.
  • the transmission of the rotary movement to the round rollers 7, 8 takes place from the toothed pinion 23 via a toothed belt 29 between a toothed wheel 24 on the bearing shaft 13 and a toothed wheel 25 on an intermediate shaft 26 mounted in the pivoting lever 14, 15.
  • a toothed wheel 27 is located thereon , which is in engagement with a gear 28 on the axis of the round rollers 7, 8.
  • the device for back-rounding book blocks 1 with the continuously running book block clamps 2 of the book block transport system is moved back and forth synchronously along the movement path over a defined distance.
  • the base plate 10a carries vertical and horizontal rollers 35 which run on tracks 34 of the machine frame.
  • a drive lever 30 engages, which is articulated on a chain 33 running around deflection sprockets 31 and 32 and moves the base plate 10a back and forth when the chain rotates.
  • more than one device for rounding the back can be arranged in a row in the bookbinding machine in order to simultaneously round the back on several book blocks.
