Definitions

  • the invention relates to a bookbinding machine for back rounding of book blocks with a conveying device which clamps the book block and with a back rounding device consisting of round rollers which act on both sides of the book block by a defined rotary movement and by pressure after the book block has been released by the conveying device.
  • the back rounding of book blocks a work step in book production, through which the book block receives the desired rounded shape of the spine and at the same time the pre-cut, is carried out in today's book block processing machines predominantly according to the roller round principle.
  • a smooth relative displacement of the individual sheets or printed sheets takes place by simultaneously rolling corrugated round rollers on the sides of the book block over a defined angle of rotation and under pressure, the sheets or printed sheets being increasingly advanced towards the center of the book block as the book block passes through the round rollers.
  • a bookbinding machine for rounding and at the same time for forming book block spines is known with a conveyor device, which intermittently conveys the book blocks in the longitudinal direction through processing stations, in that groups of mutually opposite clamping jaws lie against the sides of the book block in order to grasp them and to transport them into the round rollers or into the forming station.
  • the book block comes into the working area of two corrugated round rollers, which act on the book block and form the spine by moving the sheets or printed sheets after the clamping jaws have detached from the pages of the book block.
  • the rounding and forming machine according to DE-OS 15 36 507 can only be used in a limited performance range.
  • the object of the invention is to provide a bookbinding machine for the back rounding of book blocks of the generic type, with which a substantial increase in the working speed can be achieved.
  • the object of the invention solved by a conveyor with book block clamps which can be moved continuously in a closed orbit and by round rollers which can be driven synchronously with the book block clamps along a movement path and by recesses in clamping jaws of the book block clamps for execution of the round process can be moved back and forth to the pages of the book block.
  • 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 for simultaneous back rounding of several book blocks is arranged in the bookbinding machine.
  • the device for back rounding of book blocks 1 is, according to the invention, assigned to a book block transport system of a bookbinding machine with a plurality of book block clamps 2 lying at the same mutual distance from one another, each with a pair of clamping jaws 3 and 4 opposite one another with variable spacing, which exert a contact pressure on the pages for applying a holding force exercise one of the book blocks 1 with the back facing down.
  • the inner jaw 4 of the clamp 2 is fixed in place on a support frame 6 which runs in guides 5 of a machine frame and is connected to a transport chain by a drive chain, and the outer jaw 3 to the inner 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 clamps with the book blocks 1 held clamped are continuously driven along a closed orbit by the transport chain guided around deflection sprockets.
  • 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 supported by a drive arrangement, the detailed description of which is given elsewhere the continuously running brackets 2 along the path of movement over a defined distance in a synchronous manner and then moved back to the starting position, reversing their direction of movement.
  • recesses 3a, 4a are provided in the inner and outer clamping jaws 3, 4, through which the round rollers 7, 8 during their synchronous operation with the 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 rolling the rotary drives 7, 8 on the sides of the book block 1.
  • the two round rollers 7, 8 are simultaneously raised with their rotary movement according to the direction of the arrow in the recesses 3a, 4a of the clamping jaws 3, 4 from a lower position to an upper position shown in broken lines, as a result of which the round rollers roll off 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 bracket 2 is kept at a constant level.
  • the device for back-rounding book blocks 1, which is driven back and forth along the path of movement of the clamps 2, has a frame 10 which is composed of a base plate 10a and a support plate 10b which can be moved in a vertical plane on guide rods 17 of the base plate 10a.
  • the vertically movable support plate 10b receives on both sides of the book block movement plane in a diametrical arrangement pivotally mounted pairs of pivot levers 14, 15, in which the two round rollers 7, 8 are each freely rotatably supported at the ends.
  • the two pairs of pivot levers 14, 15 are pivoted with the round rollers 7, 8 by extending the piston rod 16b about their central pivot points toward the pages of the book block.
  • the pivoting takes place by pulling back the piston rod 16 until the pair of pivot levers 14, 15 abut against stops 18.
  • the lifting 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 starting from a common drive source, not shown on a drive lever 20, by means of the parallel lever arrangements 21, again lying on both sides of the book block movement plane and connected to one another.
  • 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 rods 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 toothed racks 22 and 22a set toothed pinions 23 on the bearing shafts 13 in rotary movement. From the pinion 23, the rotary movement is transmitted to the round rollers 7, 8 via a toothed belt 29 between a gear 24 on the bearing shaft 13 and a gear 25 on an intermediate shaft 26 mounted in the pair of pivot levers 14, 15. A gear 27 is located on this , 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 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 on the base plate 10a, 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 one behind the other in the bookbinding machine in order to carry out the back rounding simultaneously on a plurality of book blocks.
