Definitions
- the invention relates to a printing press, preferably rotogravure web press, with a printing cylinder immersed in an ink pan and a squeegee that can be attached to this.
- the object of the invention is therefore a printing press of the type specified To create a way in which a lateral, outward spraying of Color is prevented.
- this object is achieved in that on the shaft journal of the impression cylinder freely rotatable but axially immovable rings are placed, the support arms, which in the area between the paint tray and keep the doctor blade in contact with the edge areas of the printing cylinder, and that the rings by torque arms relative to the machine frame are kept non-rotatable.
- the wipers are expediently still arranged in the area of the paint tray, so that paint stripped from the edge areas over a short distance into the Ink tray can be traced.
- the wipers according to the invention are direct due to the rings that support them connected to the pressure cylinder, so that this also with an axial displacement the printing cylinder, for example a reciprocating displacement, always held unchanged in contact with the edge area of the printing cylinder without the need for tracking.
- the Torque support ensures that the wiper removes the paint from the edge areas always wipes in the same areas in relation to the paint tray.
- the wipers are expediently designed such that they are angular one leg on the jacket and the other leg on one end face of the pressure roller.
- Wipers are arranged on the doctor blade holder adjustable below the doctor blade to the end areas of the printing cylinder. These wipers ensure that even in the area the doctor blade cannot spray paint from the side of the printing cylinder.
- the wipers expediently protrude beyond the edges of the printing cylinder outside. This ensures that even with an axial displacement of the Pressure cylinder, the wipers do not leave the edge area.
- the wipers expediently consist of elastomeric material.
- the area between the upper and lower wipers is covered by a spray hood, which in the Paint tray opens. Through this spray hood is radial from the pressure cylinder splashing paint is collected and returned directly to the paint tray.
- a device with the features of the printing press can also be used for application use of glue or other coating materials on a material web.
- the pressure cylinder 1 is in the usual way by its shaft journal 3rd stored.
- the pressure cylinder 1 can in the side parts 2 in the direction of the double arrow 4 back and forth slidably, with a shift to this reversing drive can be provided.
- An ink tray 5 is held in the machine frame below the printing roller 1, which is filled to a predetermined height with ink 6, into which the printing roller 1 immersed.
- the ink tray 5 frames the lower area of the printing roller 1, so that this catches from the printing roller 1 running or spraying ink.
- a ring 6 is freely rotatable, which between the Shaft journal 3 and the jacket of the pressure roller 1 formed annular end face the pressure roller 1 and one screwed radially into the shaft journal 3 Pin 7 is held immovably in the axial direction.
- a radial Arm 8 attached to a wiper 9 made of a suitable material, for example Plastic or elastomeric material.
- This scraper is angled and lies with one leg on the end region of the jacket of the pressure roller 1 and with the other leg on the annular end face of the pressure roller.
- the stripper 9 is fastened in a groove of an angle piece 10, one of which Legs in a groove of the holding arm 8 radially displaceable to the pressure roller 1 is led.
- the holding arm 8 is provided in its web part with an elongated hole 12, which passes through a retaining screw 13 which in a threaded hole in the groove of the holding arm slidably guided leg of the elbow 10 screwed is so that the angular wiper 9 to adapt to different Move the pressure roller diameter in the radial direction and in the set one Positions can be fixed.
- the holding arm can also be adjusted in the axial direction be attached to the ring 6.
- the scraper 9 is in the direction shown in FIG. 1 in the direction of rotation A Printing roller 1 above the level of the ink 6 between the ink tray 5 and the doctor blade 15 arranged.
- the scraper 9 is expediently still in the Area of the ink tray 5 arranged to be stripped from the edges of the printing roller 1 Color traced with a short path.
- the side parts 2 with 16 consisting of projecting arms Provide torque supports on which the rings are screwed into them support radial pins 17.
- the doctor blade 15 On a doctor bar 18 extending between the side parts 2, the pivoted and lockable in the side parts 2 by end pins 19 or is held, the doctor blade 15 is attached via conventional doctor holder 20, that can be turned on the pressure roller 1 in the manner shown.
- the type of attachment of the doctor blade 15 by clamping pieces and eccentric Clamping elements are known and are therefore not described in detail.
- scrapers 22 made of a suitable material, such as plastic or elastomeric plastic, attached. These wipers 22 protrude from FIG. 3 evident way, the edges of the pressure roller 1, so that they even with an axial displacement the print roller 1 do not leave the edge area.
- the wipers 22 prevent ink from splashing sideways in the area below the doctor blade 15.
- a spray hood 24 is attached by the pressure roller splashing paint catches and leads back into the paint pan 5.
- the spray hood 24 is open at its lower end so that the color captured by it in the ink tray 5 can flow back.
