A pair of guide plates 36 (not shown one guide plate, each of which has a guide groove 36A, vertically mounted on a pair of support bases 35 (not shown one support Foundation), which is attached to the two edges along the width of the bottom surface of the colorful box 32. To the side surface of each wall 34 colorful box attached to the movable element 37, which is engaged with the guide groove 36A of the guide plate 36. The wall 34 of colorful drawer is supported by the guide plate 36, which drives the movable element 37 when the movement of the directions of the arrows a and b to the outer surface doktorova shaft 26 and from it). Between the movable element 37 and the guide plate 36 is resiliently mounted helical compression spring 38 (the first tool offset). Under the force of helical compression springs 38 corresponding wall 34 colorful mailbox tightened in the direction of the arrow (to move toward the outer surface of doktorova shaft 26). Therefore, curved front end surface 34a of the walls 34 colorful box are in close contact with the outer surfaces at the two ends doktorova shaft 26.

Two eccentric bearing 40, which is rotatably supported by two shaft ends doktorova shaft 26 that is rotatable supported by a pair of frames (not shown). At this time, the axis G2 doktorova shaft 26 is eccentric relative to the centers of rotation G1 eccentricity supports 40. The moving direction (direction along arrow a) wall 34 colorful box, which moves under the action clamped efforts helical compression springs 38, essentially perpendicular to line L, which connects the center of rotation of the G1 eccentrically support 40 and the axis G2 doktorova shaft 26, as shown in figure 4.

Supporting element 41 of the eccentric bearing 40, which is open to the outside of the frame has a protrusion 41A extending from the peripheral part of the support element 41. On the protrusion 41A of the rotary mounted extendable rod 48 mechanisms is 45 to move doktorova shaft (vehicles doktorova shaft). From part of the periphery of the support element 41 is a Cam portion 41b. The Cam portion 41b has a curved curved surface 41b, which has the axis G2 doktorova shaft as the center of rotation.

The device 45 to move doktorova shaft contains rod drive mechanism. Drive mechanism, which forms a device 45 for movement doktorova shaft comprises a drive shaft 47 and extendable rod 48. The drive shaft 47 at its one end has a handle 47A, and at its other end - portion with an internal thread (not shown). Extendable rod 48 at its one end has a threaded portion 48A, which is thread connected with a part of the drive shaft 47 having an internal thread. The other end of the extendable thrust 48 is connected to the protrusion 41A of the support element 41. The drive shaft 47 rotatably supported on the frame by means of the support element 46, so that it is possible to regulate the movement of the extendable traction 46 in the axial direction.

The support element 50, which is rotatable supported coaxially with raschetnym cylinder with axial movement of 28, on part of its periphery has a lever 50 which rotatably supports the transfer roller 27 by means of a device 55 for regulating the pressure between the rollers. Side essentially opposite the lever 50A, from the support element 50 the environment, which leads to a protrusion 50b. With the tab 50b swivel connected to the piston rod of the pneumatic cylinder 52 (second means of displacement in the claims), and the end of the rotary cylinder supported by the frame. Directed forward bias force of the piston rod 52a of the cylinder 52 through the support element 50 moves the intermediate roller 27 by moving it towards doctorname shaft 26.

The device 55 for regulating the pressure between the rollers includes an adjusting screw which is rotatable supported by the arm 50A of the support element 50, the lever which rotates with the movement of the adjusting screw forward/backward, eccentric bearing, which rotates with the rotation of the lever, etc. Device 55 for regulating the pressure between shaft regulates the pressure of the intermediate roller 27 relative to doktorova shaft 26. Such a device 55 for regulating the pressure between the rollers is a known device described, for example, in U.S. patent No. 5062359.

The intermediate roller 27 has a Cam 56, which is in contact with the curved surface 41p eccentric bearing 40. Curved surface 41p and the Cam 56 form a first Cam device 57. The purpose of a Cam device 57 is maintaining a constant pressure between doctorum shaft 26 and the intermediate roller 27, which is adjusted by the device 55 for regulating the pressure is between the shafts, even when the eccentric bearing 40 turn device 45 to move doktorova shaft.

Now you will learn how to control the amount of ink supplied from colorful box 30 to doctorname shaft 26. Initially, the device 55 for regulating the pressure between the rollers adjust to achieve a proper value of intermediate pressure roller 27 relative to doktorova shaft 26. Then, by controlling individually the many adjustment screws 33a, adjust the gap between the distal edges of the doctor blades 33 and the outer surface doktorova shaft 26.

During start-up of the printing machine, when it has not reached the predetermined speed, the amount of ink supplied from a gap between the distal edges of the doctor blades 33 and the outer surface doktorova shaft 26 to doctorname shaft 26 becomes greater or less than the normal quantity. Consequently, increase the waste of paper while printing machine reaches a predetermined speed. To solve this problem in the case when the amount of ink supplied from a gap between the distal edges of the doctor blades 33 and the outer surface doktorova shaft 26 to doctorname shaft 26, is less than the normal quantity, the drive shaft 47 of the device 45 to move doktorova rotate the shaft to rotate the eccentric bearing 40 in a clockwise direction (figure 3). That is Yes axis G2 doktorova shaft 26 is rotated clockwise around the center of rotation G1 eccentric bearing 40 as the center of rotation.

As described above, line L, which connects the center of rotation G1 eccentric bearing 40 and the axis G2 doktorova shaft 26 is essentially perpendicular to the direction of the arrow A. When the axis G2 is rotated clockwise around the center of rotation G1 as the center of rotation, ductory shaft 26 moves essentially in the direction of the arrow A. In this case, the gaps between the distal edges of the knives 33 and the outer surface doktorova shaft 26 is simultaneously increased by the same amount, so the amount of paint supplied from a gap between the distal edges of the doctor blades 33 and the outer surface doktorova shaft 26 to doctorname the shaft 26 is regulated to a normal number. In the result, you can reduce the waste of paper.

This adjustment is not required, driving separately adjusting screws 33a, and can be done at the same time, the driving device 45 to move doktorova shaft. Thus, it is possible to easily carry out the adjustment in a short period of time. Direction (direction along arrow a) doktorova shaft 26 equally with the direction of movement of the wall 34 colorful box, which moves under the action of elastic efforts helical compression springs 38. Despite the movement doktorova shaft 26 all front end surface 34a of the wall 34 crasac the CSO box is always in close contact with the outer surface doktorova shaft 26. Thus, it can be prevented leakage of paint from the colorful box 30.

The transfer roller 27, which is in contact with doctorum shaft 26, is displaced under the action of bias, the efforts of the pneumatic cylinder 52 moves toward doctorname shaft 26. When moving doktorova shaft 26 intermediate roller 27 should doctorname shaft 26 moves into contact with doctorum shaft 26. The Cam device 57 is located between doctorum shaft 26 and the intermediate roller 27. The Cam device 57 maintains a constant pressure between doctorum shaft 26 and the intermediate roller 27 in spite of the movement doktorova shaft 26. Thus, the pressure between doctorum shaft 26 and the transfer roller 27 is regulated by the device 55 for regulating the pressure between the rollers and is always maintained constant.

When the amount of ink supplied from a gap between the distal edges of the doctor blades 33 and the outer surface doktorova shaft 26 increases so that it becomes more normal amount, result in rotation of the drive shaft 47 to rotate the eccentric bearing 40 counterclockwise (figure 3). In this case, the amount of ink supplied from a gap between the distal edges of the knives 33 and the outer surface doktorova shaft 26 to doctorname shaft 26, is adjusted until the normal to the number.

The second variant implementation of the present invention will be described with reference to figure 5-7. Figure 5-7 items, similar or identical to those elements that were described above in the first embodiment of the present invention and shown in Fig. 1-4, indicated similar positions, and, where appropriate, will be omitted in their description.

The lever a rotatably supports the pressure roller 111 through the device 55 for regulating the pressure between the rollers. Stock a pneumatic cylinder 122 (the second tool offset in paragraph 4 of the claims) of the swivel is connected to the protrusion 121b, while the end of the rotary cylinder supported by the frame 110. Rolling roller 111 is shifted forward (in the direction of rotation of the support element 121 clockwise) bias force of the rod 122b of the pneumatic cylinder 122 for entering into contact with the rolling cylinder 16.

As shown in Fig.7, the supporting element 124 in the axial direction is supported by having a small diameter part 40A eccentric bearing 40 about the axis G2 doktorova shaft 26 as the center of rotation. Supporting element 124 at its peripheral part has a lever 124A beaches and a protrusion (not shown). The lever 124A beaches rotatably supports the pressure roller 112. The rod 125 of the pneumatic cylinder 125 (second means of displacement in paragraph 4 of the claims) of the swivel is connected to the protrusion of the support element 124, while the end of the rotary cylinder supported by the frame 110. Rolling the roller 112 is displaced under the action of directional ago (the direction of rotation of the support element 124 counterclockwise) bias thrust 125 a of the pneumatic cylinder 125 to enter into contact with the rolling of the cylinder is 16.

Supporting element 127 in the axial direction is supported by having a small diameter part 40A eccentric bearing 40 about the axis G2 doktorova shaft 26 as the center of rotation. As shown in Fig.6, a basic element 127 at its peripheral part has a lever a, which rotatably supports raskatny cylinder 114 (body rotation in paragraph 6 of the claims). On the frame 110 for clamping lever a support element 127 vertically extend two rods 128 (guide members), which determine the direction of movement Raskatov cylinder 114.

Rolling the cylinder 16 provided with Cams 130 and 133, which are in contact with the Cams 131 and 134 rolling rollers 111 and 112. The Cam 130 forms a Cam device 132, which maintains a constant pressure between the rolling cylinder 16 and the rolling roller 111, when the eccentric bearing 40 turn device 45 to move doktorova shaft. The Cam 133 forms a camming device 135, which maintains a constant pressure between the rolling cylinder 16 and the pressure roller 112, when the eccentric bearing 40 turn device 45 to move doktorova shaft.

In this design in order to simultaneously adjust the clearance between the outer surface doktorova shaft 26 and the distal edges of the doctor blades 33, handle 47A during playback is with the drive shaft 47 in a clockwise or counterclockwise in the same manner, as with the first embodiment of the invention. By means of the drive shaft 47 and extending thrust 48 rotate the eccentric bearing 40 clockwise or counterclockwise to move doktorova shaft 26 in the direction along arrow a or B.
