Definitions

  • the subject of the present invention is a sleeve sleeve holder spacer for machine in particular flexographic and the arrangement of a printing cylinder full.
  • Flexographic printing machines include several successive groups of impressions depending on the number of colors, each group having the role of printing, in the given color assigned to it, an image in sort of get the graphical representation in color such than desired.
  • Such machines have very printing capabilities important so that they produce at high rates images of great graphic quality. Also, the operators are regularly required to change the cylinders carrying the plates.
  • the pictures are prepared, that is to say assembled and wedged then fixed on the sleeve, then the plate or engraved sleeves are mounted on additional cylinders while a first game is in place and running on the machine.
  • the park must be doubled, otherwise, it must stop the machine, remove the clichés used, position the new ones on the sleeves, which is impossible from the point of profitability.
  • a sleeve made of material composite can be worn by one person, without break labor laws, regardless of diameter, in the current range. This avoids all handling with the hoist with all the drawbacks therein attached. As a result, it becomes not only unnecessary to have a set of metal support cylinders covering each development and developments immediately but we also remove the second set of cylinders in the same development.
  • the object of the present invention is therefore to propose spacer sleeves which solve this problem of double series in the same development and which, more general, allow to use cliché sleeves or trimmed and laser engraved of small thickness, this for all developments, while requiring a reduced fleet of metal support cylinders. Thin sleeves are renewed for each shot because they cannot be refilled with rubber, or they may be damaged when removing the photo.
  • the present invention relates to a arrangement of a complete cylinder of flexographic printing, comprising a hollow support cylinder of a given diameter, designed to be rotated and equipped with a internal compressed air supply with nozzles through, arranged in an angular distribution given, at the periphery substantially along a circle to in the immediate vicinity of the insertion end, and which characterized in that it comprises at least one sleeve interlayer with an internal diameter compatible with the outside diameter of the support cylinder for tight mounting radially, and an outside diameter compatible with the inside diameter of a thin sleeve bearing the image for mounting tightened radially with an outside diameter equal to that of the development sought, said intermediate sleeve comprising nozzles substantially along a circle, having the same angular distribution as that of the cylinder support and means for closing off these nozzles so as to allow the mounting of this intermediate sleeve on the support cylinder.
  • the means shutter include a ring mounted fixed in translation, in particular thanks to a fixed ring, along the axis longitudinal of the intermediate sleeve and movable in rotation between two positions, open and closed, in a projection arranged in line with the nozzles of the intermediate sleeve, said ring itself being provided with nozzles having the same angular distribution than that of the cylinder nozzles support and spacer sleeve with open position corresponding to the coincidence of the nozzles of the sleeve interlayer with the ring nozzles and a position closed in which the nozzles of the ring are offset compared to those of the sleeve.
  • the movable ring includes seals, to prevent air leakage compressed between the ring and the sleeve and the ring is mounted in a projection formed from the inner periphery.
  • the means shutter include fixed hollow through inserts the thickness of the intermediate sleeve, said inserts having an angular distribution identical to that of the nozzles of the support cylinder, said inserts being tapped for receive removable threaded plugs.
  • these sleeves include indexes so as to allow the alignment of the different nozzles according to radial directions.
  • the invention also relates to the sleeve insert for the implementation of the indicated arrangement above.
  • the central tap 20 for introducing compressed air is generally arranged coaxially to one of the axes of the cylinder metal support.
  • the support cylinder is made of metal and the intermediate sleeve just like the thin sleeve are made of material polymer.
  • the intermediate sleeve is produced according to the teaching of the French patent application No. 94 06417 (corresponding to document EP-A-0 683 040, published on November 22, 95).
  • the metal support cylinder 10 comprises nozzles 22 distributed evenly, along an opening circle, at the periphery of said cylinder in order to put in communication the inside of this cylinder with the outside, the path of air being symbolized by arrows 26.
  • the intermediate sleeve 12 includes a fixed ring 28 in rotation relative to the body of the intermediate sleeve and a movable ring 29, free to rotate on the fixed ring 28.
  • the fixed ring has an outside diameter equal to that of the outer diameter of the sleeve, and an equal inner diameter the diameter of a projection 30 formed at the end of the body intermediate.
  • This fixed ring has a reduced diameter over part of its length, equal, apart from play, to the inside diameter of the movable ring.
  • the movable ring 29 has an outside diameter equal to outside diameter of the body of the intermediate sleeve and at outer diameter of the fixed ring in its diameter part not reduced.
  • Nozzles 36, 34 are machined respectively through the thickness of the reduced diameter part of the fixed ring 28 and through the thickness of the movable ring 29.
  • the sleeve body also carries nozzles 38 in the part located at the right of the projection.
  • this intermediate sleeve is carried out according to steps 2A to 2C.
  • a means of fixing such as a cyanoacrylate type adhesive sold under the name "loctite" taking the precaution of making coincide the nozzles 36 of the fixed ring with the nozzles 38 of the projection 30 of the intermediate sleeve.
  • the movable ring 29 can rotate relative to the reduced diameter portion of the fixed ring while this same fixed ring is immobilized in translation thus retaining the movable ring.
  • FIG. 3A it can be seen that the nozzles 22, 34, 36 and 38 are distributed according to angular sectors identical so that in a given position they can be aligned.
  • the assembly of such an assembly is carried out by introducing pressurized air through the nozzle 20 which passes through the nozzles 22 of the support cylinder 10.
  • the operator puts on the intermediate sleeve 12 by the end of the cylinder provided with these nozzles 22.
  • the film air allows easy insertion of this sleeve interlayer.
  • the ring 29 is in the position shown in the Figure 3B, i.e. a position in which the nozzles 36 and 38 are coincidental by manufacture but in which the nozzles 34 are not coincident with nozzles 36 and 38.
  • the intermediate sleeve once threaded to the maximum and correctly positioned on the metal support cylinder, is blocked on this support cylinder by rotation of the ring mobile 29 in order to bring the nozzles 36 and 38 into coincidence with the nozzles 34, i.e. in the position of the Figure 3A.
  • the thin sleeve 14 is then threaded in turn on the spacer sleeve 12 because the air that escapes through the four sets of nozzles form an air film which allows a very easy assembly.
  • the operator can then mount a new sleeve thin.
  • FIG. 4 shows a variant of the sleeve insert in which the ring has been removed and replaced by 40 threaded cylindrical inserts in which threaded plugs 42 can be screwed.
  • the threaded plugs play the same role as the ring and if they are a little less flexible to use, their price of returns is lower.
  • a printer wishes to fulfill an order for 10 models printing in four colors, with the same print development, for example 820 mm.
  • This printer has only one set of metal support cylinders of 680 mm, i.e. fifteen developments lower than that of the ordered. So there are 40 engraved pictures and 10 changes in machine then it has the opportunity to make the solutions following.
  • the printer must stop his machine after each print, remove the cylinders, remove the shots from these cylinders, reposition the new printing shots following. Stop from 5 am to 6 am depending on the operator skill.
  • the ring is formed in a projection machined from the inner periphery of the intermediate sleeve but such projection can be made from the periphery outside.
  • the intermediate sleeves are produced according to the teaching of patent application FR-A-94 06417 (corresponding to the document EP-A-0 683 040, published on 22.11.95).
  • Each sleeve includes a succession of layers of honeycomb material preferably embedded in a resin matrix.
  • the manufacturing support is a cylinder metal rectified to the diameter of the subsequent support cylinder.
  • the inner peripheral surface is of appearance polished.
  • the outer surface is adjusted to the exact diameter allowing tight fitting of the thin sleeve.
  • composition of the resin is adapted to give the sleeve a calculated shrinkage which ensures a tight fitting radially.
  • a mechanical machining known and within the reach of the man of art.
