Definitions

  • the present invention relates to a device for adjusting the position of a cylinder in printing machines, particularly for scoring units.
  • a cylinder particularly a scoring cylinder in printing machines
  • the position of a cylinder is adjusted so as to place the scoring cylinder in contact with a cylinder located below it, so that the scoring cylinder applies pressure to the underlying cylinder, with paper or another medium to be scored passing between the two cylinders.
  • Conventional scoring units in printing machines are generally provided with a system for adjusting the position of the scoring cylinder with respect to the underlying cylinder.
  • Said adjustment device is provided with presser elements which are moved so as to apply pressure to the upper surface of the scoring cylinder, so as to keep it in a stable position with respect to the cylinder located below it.
  • These presser elements are generally constituted by a frame which is arranged above the scoring cylinder and is moved so as to make contact with the scoring cylinder.
  • the aim of the present invention is to provide a device for adjusting the position of the cylinder in printing machines, particularly for scoring units, in which the stroke for the adjustment of the adjustment device is considerably shorter than currently provided in conventional devices.
  • an object of the present invention is to provide a device for adjusting the position of a cylinder in printing machines, particularly for scoring units, in which the time required for adjustment is considerably shorter than in conventional adjustment devices.
  • Another object of the present invention is to provide a device for adjusting the position of a cylinder in printing machines, particularly for scoring units, in which the presence of the presser elements arranged above the scoring cylinder is substantially eliminated, improving the overall dimensions of the scoring unit.
  • Another object of the present invention is to provide a device for adjusting the position of a cylinder in printing machines, particularly for scoring units, which is highly reliable, relatively easy to manufacture and at competitive costs.
  • a device for adjusting the position of a cylinder in printing machines, particularly for scoring units which comprises a presser element which is meant to apply pressure to a cylinder of said printing machine, characterized in that said presser element comprises a box-like body which is provided with engagement means for arranging it in seats formed in two shoulders which are suitable to support said cylinder, said box-like body being provided with fine adjustment means in order to precisely adjust its position with respect to said cylinder on which said box-like body is meant to apply pressure.
  • the device for adjusting a cylinder in a printing machine comprises, for example in the case of a scoring unit, in which the reference numeral 2 designates a shoulder for supporting a first scoring cylinder 3 and a second contact cylinder 4, a presser element 5 which is meant to apply pressure to the upper surface of the scoring cylinder 3.
  • the presser element comprises a box-like body 6 which is shaped substantially like a parallelepiped and with whose ends two conveniently L-shaped brackets 7 and 8 are associable; each one of said brackets is provided with at least one contact wheel 9. Conveniently, at least one of the ends of the box-like body is beveled.
  • the box-like body 6 has at its ends, in a position which is adjacent to the connecting point of the brackets 7 and 8, two respective pairs of wings 10 and 11 which protrude laterally with respect to the longitudinal extension of the box-like body 6.
  • Each one of the wings 10 and 11 is provided with a protruding tooth 12 which is suitable to engage the shoulder 2 and the opposite shoulder, designated by the reference numeral 15, which form the supports for the scoring cylinder 3 and for the contact cylinder 4.
  • each one of the shoulders 2 and 15 is provided with a guiding seat for positioning the presser element 5.
  • each shoulder 2 and 15 is provided with a slot 16 arranged vertically with respect to the longitudinal axis of the cylinders 3 and 4.
  • the sides of the slot 16 are shaped so as to accommodate the presser element 5.
  • at least one side of the slot 16 is shaped so as to have a recess 17 with teeth 18 formed therein which are arranged mutually opposite to teeth 19 formed at the opposite edge of the slot 16.
  • Figure 2 illustrates the engagement of the teeth 12 of the pairs of wings 10 and 11 at slots 20 and 21 formed respectively between the teeth 18 and 19 arranged laterally to the slot 16.
  • brackets 7 and 8 The coupling of the brackets 7 and 8 to the lower surface of the box-like body 6 occurs by means of a threaded pin 24 which engages a female thread accommodated in the body of the bracket 7, and the screwing or unscrewing of the pivots 24 allows to vary the position of the brackets 7 and 8 with respect to the box-like body 6.
  • the user first of all inserts the box-like body 6, with its pairs of wings 10 and 11 and the teeth 12, in the mutually opposite slots 16 formed in each one of the shoulders 2 and 15 and places the box-like body 6 as close as possible to the scoring cylinder 3, accordingly engaging the teeth 12 in the slots 20 and 21 formed between the teeth 18 and 19 of the sides of the slots 16 and 17.
  • the user then performs fine adjustment by acting on the threaded pins 24 so as to move the brackets 7 and 8, so that they make abutment contact against the upper surface of the scoring cylinder 3, at its central region, so that the wheels 9 rest at a lateral region of the scoring cylinder 3, so as to keep the cylinder locked in position.
  • the insertion of the box-like body 6 in the slot 16 occurs by placing the box-like body so that the wings 10 and 11 are in contact with the side 28 of the cavity 17, and once the suitable position of the box-like body 6 with respect to the scoring cylinder 3 has been found, the teeth 12 are engaged in the corresponding cavities 20 and 21 of the sides of the slot 16 by way of a translatory motion, i.e., a motion toward the opposite side of the slot 16, thus locking the box-like body 6 in position.
  • the adjustment device according to the invention allows to fully achieve the intended aim and objects, since the adjustment stroke to which the presser element must be subjected is reduced to a fine adjustment performed by means of the adjustment screws that move the brackets, since coarse adjustment of the position of the presser element is performed manually by directly placing the presser element at the chosen height.
  • the adjustment device allows to reduce the dimensions of the presser element to those of the box-like body, accordingly reducing the dimensions of the scoring unit and facilitating access to the corresponding cylinders.
  • the materials employed may be any according to requirements and to the state of the art.
