Definitions

  • the present invention relates to a rotary cutting apparatus which can be used more particularly in printing and shaping lines for folding cardboard boxes and self-adhesive labels.
  • These devices are generally based on the principle of rolling, one on top of the other, of two superimposed cylinders, of parallel axes, one of which, namely the cutting cylinder proper, carries cutting knives, obtained by etching, while the other cylinder or “anvil” cylinder is smooth.
  • the two cylinders may have complementary engraved cutting knives.
  • the drive in rotation of the two cylinders, at the same peripheral speed but in opposite directions to each other, is ensured by connecting gears of the same pitch diameter chosen so that it remains, between the two cutting cylinders, a constant distance, as small as possible, which is necessary to ensure a good cut of the sheet of cardboard or paper passing between them, without there being any contact between the metal parts ensuring the cut .
  • rollers or raceways which are fixed to the ends of the two cylinders while being perfectly concentric with them, and which roll over one another.
  • the diameter of each of these rollers or raceways is equal to the pitch diameter of the connecting gear. It is then possible to apply, on the raceways, the external cutting pressure, which is necessary and sufficient to compensate for the reaction which appears during the cutting of cardboard. It is obvious that the original spacing will be greater the greater the elastic deformation of the cylinders.
  • the present invention relates to improvements made to a rotary cutting device of the aforementioned type making it possible to very significantly reduce the bending or deflection suffered. by the cutting cylinder during a cutting operation and to keep the spindles of the upper cutting cylinder perfectly embedded, even after heating resulting from a certain working period of the device.
  • this rotary cutting apparatus comprising a frame supporting, between two parallel vertical uprights, two superimposed cutting cylinders, with parallel axes, namely an upper cutting cylinder and a lower cutting cylinder respectively integral with rolling raceways on each other, each cutting cylinder comprising, at each end, a coaxial spindle mounted for rotation in a bearing block which can slide vertically on the two respective uprights, each of the upper bearing blocks being extended at its upper part, towards the inside of the device, by a cantilevered part subjected to the action, downwards, of a vertical pressurizing cylinder mounted at the top of the device, while each of the bearing blocks lower part is extended, at its lower part, towards the inside of the apparatus, by a cantilever part extending above a stop carried by the mount corresponding ant and with which it is in contact, is characterized in that it comprises, between each pair of upper and lower bearing blocks, a counter-pressure stop integral with the upper bearing block and bearing on the lower bearing block by l intermediary of an elastic means working in compression
  • Figure 1 is a partial vertical sectional view of a rotary cutting apparatus according to the invention, in the position in which it is stopped, before a work period.
  • Figure 2 is a vertical sectional view taken along line II-II of Figure 1.
  • Figure 3 is a partial sectional view, on a larger scale, of an embodiment of an elastic pressure backpressure stop, in the position it occupies after a certain period of work of the apparatus .
  • the rotary cutting device which is partially shown in Figure 1, comprises a frame consisting of two parallel lateral uprights 1, interconnected by horizontal crosspieces not shown. Only one side of the device is shown in Figure 1, the other side being symmetrical to the previous one.
  • Each upright 1 is notched, in its upper part, with an opening 3 extending vertically, of rectangular shape and opening into the upper horizontal face of the upright.
  • an interchangeable cutting device essentially consisting of two upper 4 and lower 5 cutting cylinders, with parallel horizontal axes, between which a sheet of paper or cardboard to be cut must pass.
  • the upper cutting cylinder 4 is extended, at each of its ends, by a coaxial spindle 4a, and it is integral with two raceways 4b located at a distance from the two end faces of the cutting cylinder 4 and between which is the engraved part of the cylinder 4.
  • the lower cutting cylinder 5 is extended, at each of its ends, by a coaxial rocket 5a.
  • the upper raceways 4b having the same diameter which is slightly greater than that of the upper cutting cylinder 4, roll on the periphery of the lower cylinder 5 if the latter is smooth, thus constituting an "anvil” cylinder, or else on raceways 5b of the lower cylinder if the latter is also engraved.
  • the diameter of the upper raceways 4b is equal to that of the lower raceways 5b and the pitch diameter of the connecting gears 7, 8, respectively secured to the spindles 4a, 5a of the cutting cylinders 4, 5, outside amount 1.
  • These connecting gears 7, 8 are engaged with each other and are rotated from the general control of the device.
  • the spindles 4a and 5a of the cutting cylinders 4, 5 are respectively rotatably mounted in superimposed blocks forming bearings, namely upper and lower bearing blocks 9 and 10, engaged closely in the openings 3 and able to slide vertically therein.
  • Each upper bearing block 9 is extended, at its upper part, towards the interior of the apparatus, by a cantilever part 9a extending above the end part of the upper cutting cylinder 4.
  • each lower bearing block 10 is extended, at its lower part, towards the interior of the apparatus by a cantilever part 10a which extends below the end part of the lower cutting cylinder 5 and above a fixed insert stop 11.
  • This stop 11 is fixed, by means of screws, to the internal face of the corresponding upright 1 so that its upper horizontal face is situated at a level slightly higher than that where the lower edge of the opening 3 is located.
  • a pressurizing frame 12 which comprises a central cross member 13 carrying, at each of its ends, a vertical pressurizing cylinder 14.
  • the rod of this cylinder s' extends downward, and its lower end is located just above the cantilever portion 9a of the upper bearing block 9 and in contact therewith.
  • Each vertical pressurizing cylinder 14 is mounted on the cross member 13 of the pressurizing frame 12, so that the vertical axis of the jack 14 is contained in a vertical and transverse plane P passing through the lower stop 11 and located between the vertical and transverse median plane P1 of the neighboring upper raceway 4b and the neighboring upper bearing block 9.
  • At least one counterpressure stop 15, integral with the upper bearing block 9, of adjustable height, is interposed between each pair of upper 9 and lower bearing blocks 10.
  • This counterpressure stop 15 is located substantially in the vertical plane and transverse median P2 common to the two upper 9 and lower 10 bearing blocks of the same pair of blocks.
  • Means are provided for adjusting, at will, the height of the adjustable back pressure stop (s) 15.
  • These means may include, for example, two vertical rods 16, passing from top to bottom each upper bearing block 9, on the one hand and on the other side of the spindle 4a of the upper cutting cylinder 4, and of which at least the lower parts 16a are threaded and screwed into corresponding tapped holes provided in the lower part of the upper block 9.
  • the two lower parts 16a of the rods 16 constitute the back-pressure abutment 15 by bearing, by their lower front faces, on the upper face of the lower bearing block 10.
  • the two rods 16 are integral with respective pinions 17 engaged with a common central pinion 18 integral with a vernier 19. It is thus possible, by rotating this vernier 19, to adjust the height whose lower parts 16a of the rods 16 protrude below of the bearing block 9 and therefore the spacing between the two blocks 9 and 10.
  • the pressurizing frame 12 When the rotary cutting device according to the invention is set in pressure, the pressurizing frame 12 extends horizontally and when each jack 14 is put under pressure, its rod is pushed back down against the upper bearing block 9.
  • the force F produced by the jack 14 is exerted downward in the vertical and transverse plane P passing through the axis of the corresponding jack 14 and it is collected by the fixed stop 11.
  • the external pressure force F directed downwards, opposes a first reaction force F1, directed upwards, acting between the raceways 4b and 5b and a second reaction or back-pressure force F2, directed upwards, acting between the two rockets 4a and 5a and tending to separate them from one another.
  • Such a rocket embedding device 4a functions satisfactorily at the start of a work period but after a certain time, the cutting cylinder 4 and the anvil cylinder 5 heat up and the expansion which results therefrom resulting causes the axes of these two cylinders 4 and 5 to be spaced apart.
  • This spacing is absorbed without problem by the vertical cylinder 14, the rod of which retracts somewhat, but because the axis of the upper cutting cylinder 4 moves upwards relative to the axis of the lower anvil cylinder 5 kept fixed, each upper bearing 9 moves upwards relative to the lower bearing 10 remaining fixed and the lower front face of the back-pressure abutment 15 moves away from the face upper support of the lower bearing block 10, so that this backpressure stop no longer plays its role and that the backpressure force F2 decreases.
  • This elastic means 21 which can be composed, for example, Belleville washers or an elastomer block, is housed in a recess 22 formed in the upper face of the lower bearing block 10.
  • the elastic means 21 bears on the bottom 23 of the recess 22, the bottom to which is normally applied the lower front face 16b of each rod 26.
  • the threaded lower part 16a of each rod 16 is extended downwards by an end portion of smaller diameter 16c which extends to the lower front face 16b of the rod 16.
  • the elastic means 21 (Belleville washers or annular elastomer block) surrounds the end portion of small diameter 16c and it abuts upwards against the annular shoulder 24 formed between the threaded lower part 16a of the rod 16 and the end part 16b of small diameter.
  • each rod 16 When the rotary cutting device is at a standstill, its constituent elements therefore being relatively cold, and when it is pressurized, each rod 16 is adjusted so that its lower front face 16b is in contact with the bottom 23 of the recess 22, as shown in Figures 1 and 2. In this position the elastic means 21 is strongly crushed. After a certain working time, the cutting cylinders 4 and 5 have heated up and expanded and the axis of rotation of the upper cylinder 4 has moved upwards, thus moving the lower front face 16b away from the counter stop. pressure 15 of the bottom 23 of the recess 22, as shown in FIG. 3.
  • the characteristics of the elastic means 21 are chosen such that this elastic element 21 continues to exert upward a reaction or counter force pressure F2 which makes it possible to retain the embedding of the spindle 4a of the upper cutting cylinder 4. Therefore the initial setting is found to be kept practically constant whatever the temperature of the cutting cylinders.
