Definitions

  • the invention relates to a device for automatically adjusting the deceleration of the notebook before folding in the square folds of printing press folders.
  • the angle fold system is well known to manufacturers of folding presses for web printing presses.
  • the object of the present invention is to make automatic adjustment of the devices for slowing down the notebook before folding.
  • the notebook (1) to be folded is brought to the folding station between two sets of conveyor belts (2) and (3).
  • This stop (4) is notched in line with the belts (2) and (3) to allow them to pass.
  • the notebook (1) on the other hand stops on the bûté (4), which it cannot cross.
  • Two folding rollers (5), rotating in opposite directions, are placed under the table (6) which is notched in its center to allow passage to the notebook (1) during folding.
  • a reciprocating knife (7) mounted oscillating above the folding rollers (5) and arranged so that its edge is parallel to the contact generators of the rollers (5), makes it possible to introduce the notebook between the rollers (5 ).
  • the knife is articulated around an axis (8), parallel to that of the rollers (5) and receives a movement of a connecting rod and crank mechanism (9) and (10).
  • the rotation of this connecting rod and crank system is ensured by the following kinematic chain: bevel gear (11 and 12), helical gears (13 and 14), (15 and 16).
  • the gear (16) is rotated by the shaft (17), linked to the control of the folder, so that each book produced, the shaft (17) makes a turn.
  • crank pin (9) The locking of a crank pin (9) on its shaft is carried out so that the knife (7) touches the bending book (1), substantially at the moment when the latter reaches the fixed stop (4).
  • the axial position of the helical gears (14) and (15), integral with each other, is determined by a screw nut system.
  • the screw (18) is stopped in translation to the frame, but free to rotate. It is screwed into the nut (19), stopped in rotation but free axially and which therefore, by means of a ball bearing (20) axially displaces the train of helical gears (14) and (15).
  • the screw is linked by gears (21) and (22) to an electric motor (23).
  • the nut (19) is further provided with limit switch contacts (24) and (25) which limit the travel of this nut and the axial movement of the gears (14) and (15).
  • the motor (23) is electrically controlled by a control box (26), to which are also connected the limit switches (24) and (25).
  • This cell is also connected to the control box (26) which receives, in addition by a conductor (28), a signal during the whole time when the press conductor presses the "+ fast" button at press control console to increase press speed.
  • the whole system of axial displacement of the pair of helical intermediate gears (14) and (15) makes it possible to vary the phase of the folding knife (7) relative to the time of arrival of the notebook (1) on the stop (4).
  • the adjustment of the phase of the knife (7) relative to the abutment of the notebook (1) makes it possible, precisely, to make the knife (7) touch the notebook, at a distance from the stop (4) more or less and this while the folder is running.
  • the present invention relates to an automatic mechanism which makes it possible to adjust the advance of the knife so that the notebook to be folded reaches "just" the stop (4) whatever the grammage of the notebook, the pagination or the various braking forces which are can apply to it: brushes, vacuum and whatever the speed of the machine.
  • This relay is reset each time if the pulses follow one another with a period less than its setting time "t". It delivers, in this case, a permanent signal "notebook in abutment".
  • phase adjustment motor ( 23) turns in the "more advance” direction until the notebook is no longer in abutment.
  • the phase adjustment motor starts again in the "less advance” direction to bring the notebook just in abutment.
  • the device according to the invention further comprises two different chains for controlling the phase adjustment motor (23).
  • a control chain in the "more advance” direction comprising a relay (K 1) and said contact (30).
  • a control chain in the "less advance” direction comprising a relay (K 2) and said contact (31).
  • an indicator light (42) allows the operator to appreciate the fact that the notebook comes or does not come into abutment.
  • the relay (K 1) phase motor control will go up and self-power through its contact (36), making more advance until the cell, no longer seeing the notebook, opens the contact (30) and closes the contact (31).
  • the stop arrival detector can be a photoelectric cell as described above, whether of the transmission type or of the reflection type, or even of the pneumatic pneumatic type or even a simple electrical contact or a piezoelectric or capacitive detector or any other kind of contact.
  • the mechanism of the square fold can be of the well-known type known as a "reel", in which the knife or blade describes a hypocycloid with two cusps.
  • phase shift can also be done by epicyclic gear or by harmonic differential reducer, instead of the system with axial displacement of chevron gears, without departing from the scope of the present invention.
  • Figures 4 and 5 show a method of slowing down the notebook produced by action on a suction force acting on the notebook, as described in French patent 8309350 of June 6, 1983 in the name of the Applicant.
  • a fan (45) produces a vacuum in two boxes (46) located under the square fold table (6) and applying to the notebook (1) by a series of holes (47) drilled in the table.
  • the throttle valve (43) mounted in “by pass” and controlled by a motor (44) is under the control of the automation (26) according to an action by "more vacuum” and by "less vacuum".
  • the advance control is manual. It is also possible to control the notebook's braking brushes, brushes which are usually mounted near the stop, in contact with the notebook, for controlling the automation (26).
  • the invention also relates to any combination of these various complementary slowdown modes.
