Definitions

  • the invention relates to a paint chamber comprising two doctoring strips on which in each case a squeegee sheet is fastened, wherein between the edges of the squeegee plates an opening is formed by the color from the ink chamber to a Ink transfer roller is transferable.
  • the object of the invention is an improved ink chamber of the generic type To provide a type that allows a quick and easy exchange, without any, remaining in the ink chamber quantities of paint in the Printing machine can drain.
  • This object is achieved in that the opening in the Color chamber is formed between the edges of the doctor plates, by a relative movement of the doctor blades is closed to each other.
  • the two doctoring strips relative are movable relative to each other, either both doctoring strips simultaneously be movable or even a doctor blade is fixed and the other Doctor bar is movable relative to this.
  • This relative mobility to each other is achieved that the attached to the squeegee Squeegee plates follow this movement immediately.
  • by a suitable choice of movement can be achieved that the two edges the squeegee plates are moved towards each other on the respective squeegee bars, so that at the relative movement first the opening between the edges the squeegee plates are reduced until this opening is completely closed, when the doctor blades touch.
  • the opening between the edges of the doctor plates by a rotational and / or translational Movement of at least one doctor bar is closed.
  • This simultaneous rotation of at least one doctor bar and the lowering of the Color chamber may preferably be realized by a mechanism übe r the both movements are executed synchronized, so that the tightness of the Color chamber opposite the ink transfer roller for the entire Daue r the Movement of the squeegee is guaranteed until the opening between the n Doctor blade is completely closed.
  • This mechanism may e.g. by Be realized lever and / or a transmission.
  • a particularly simple construction of a color chamber according to the invention Enabling such a translatory movement, e.g. one movable arranged doctor bar against a fixed doctor bar results for example, in that one ink chamber has two side elements, between which the respective doctor strips are arranged, wherein a Rakelmann firmly and another squeegee slidably with the Page elements is connected.
  • a color chamber substantially results in the manner of a frame-shaped element, the two doctoring strips two in the Substantially parallel to each other long frame members and the form two short frame elements both side elements.
  • Such a displaceable arrangement can be realized, for example be that between the ends of the sliding squeegee and the Side elements each have a guide mechanism is formed.
  • a guide mechanism can accordingly the movable Rakel bar translationally be moved to the fixed doctor bar, which is the corresponding edges of each attached to the squeegee Move the doctor blades towards each other until the opening between them Edges is completely closed and a paint chamber of one Ink transfer roller of a printing press can be lifted without that Color drips into the printing press.
  • the guide slot has a course deviating from a straight course, in particular represents a curved curve, e.g. the course of the Lateral surface curvature of the ink transfer roller simulates.
  • the guide slots in the side elements so be formed such that upon displacement of the sliding doctor bar itself Either the edge of the moved doctor blade exactly on the edge of the fixed squeegee plates or in a rather preferred Execute the edge of a doctor blade, in particular the shifted Doctor blade on the surface of the other doctor blade, in particular the stationary doctor blade, hangs up.
  • This will be a particularly good Tightness of the ink chamber achieved since the front side of the edge of the slidable doctor blade with a sufficient force on the surface of the other doctor blade can be pressed.
  • a corresponding sealing device e.g. in Form of a final element, which the paint chamber laterally against leaking paint seals, in particular in a final element a Seal may be provided, which on the one hand to the lateral surface of the Ink transfer roller applies and on the other to the upper surface at least a doctor blade preferably applies both doctor blades.
  • the seal in conjunction with the closing element can be a lateral, form a sealing wall area, which prevents the paint from being sideways Color chamber emerges.
  • this can Seal be formed such that it the movement of a doctor blade sealingly yields, allowing the contact of the gasket with the upper surface of the gasket moving doctor blade during the entire, in particular translational Movement of the doctor blade is maintained.
  • FIG. 1 shows a perspective view of a color chamber according to the invention 1, which in the present construction is substantially formed of two Side elements 2, between which two doctor strips 3 and 4 extend, the are arranged substantially parallel to each other.
  • trimmed ends of the two doctor strips 3 and 4 are by means of appropriate Terminal strips 3a and 4a on the doctoring strips 3 and 4 doctor plates 6 and 5 such attached that in a known manner between the two doctor blades a large, is formed obtuse angle.
  • FIG. 3 shows a side sectional view of the arrangement of a End element 9 on a side member 2, in which the lateral ends the doctor plates 5 and 6 eino.
  • a seal 10 is arranged, which has a stationary part 10 a and a approximately finger-shaped extending therefrom part 10b has.
  • This seal 10 is located with its lateral region on the rear wall 9 a of the End element 9 and at the same time with their lower areas on both the upper surfaces of the respective doctor plates 5 and 6 as well as on the Lateral surface of the ink transfer roller, not shown. That's how it turns out Overall, a lateral tightness of the ink chamber system.
  • the training of the End element 9 and in particular also of the side element 2 is in the Figure 4 shown in more detail.
  • the doctor bar 3 with the associated doctor blade 6 stationary and immovable, e.g. by screwing, is attached. Accordingly forms the overall arrangement of the two side elements 2 and the squeegee. 3 a rigid, essentially U-shaped profile, in which the two in the Color chamber 1 facing surfaces of the side elements, the two legs form, between which the movable doctor bar 4 with the associated Doctor blade 5 is slidably disposed.
  • the guide slot 11 is designed to be slightly bent, this bend at least in part the course of the lateral surface of the not shown Color transfer roller traced so that the edge of the doctor blade 5 in the translation of the squeegee 4 in the guide slot 11 not from this Lateral surface lifts off or an impermissible force on the Color transfer roller exerts, and thus the tightness of the ink chamber to the ink transfer roller during the closing operation of the opening. 8 remains guaranteed.
  • the opening 8 of the ink chamber 1 between must close the two edges of the doctor plates 5 and 6, a must First operator to move the locking pin 13 in the holder 12 so that one end of the locking pin 13 is disengaged from the retaining element 14 device, so that then the squeegee 4 are moved to the doctor bar 3 can.
  • the distance between the two doctor strips 3 and 4 is preferably perpendicular chosen to the longitudinal direction of the ink chamber such that the two doctor strips. 3 and 4 are overlapped with the fingers of the hand of a serving person can, so by closing a hand in the direction of a fist the two doctoring bars are pushed towards each other.
  • this movement by a suitable Mechanism which a parallel displacement of the doctor bar 4 in the direction of Doctor blade 3 ensures, by means of a lever by hand, pneumatic or motorized, which additionally has the advantage of an eventual Canting the sliding squeegee in the side channels too prevent.
  • pneumatic or motorized which additionally has the advantage of an eventual Canting the sliding squeegee in the side channels too prevent.
  • Such a recess 16 can, for example, by a longitudinal direction the ink chamber 1 in one or both blade strips 3.4 extending groove 16th be educated.
  • this groove 16 in those squeegee. 3 be arranged, which is the so-called closing squeegee of the ink chamber. 1 is assigned, so that the rotating paint roller during operation of the ink chamber. 1 rolls on the opposite doctor bar 4.
  • a reverse Arrangement possible.
  • the inventive design of the ink chamber shown is a simple way of creating color chambers on printing presses during to replace the operation, as by a displaceability of the doctor blades closing the color passage opening between the edges of each other Doctor blades is possible.
