EP1407882A2 - Method for adjusting a roller in a printing machine - Google Patents

Abstract

The method involves moving an abutment (32) to limit a stroke (95) of a holder (03) for an axle or pin (06) of an adjustable cylinder at a space (43) from a counter bearing formed as a base plate (31,42) directly or indirectly supported at a machine frame (08). The adjusted cylinder is pressed against the first cylinder (01) by a variable adjustment force over its axle holder (03) and is held there. The abutment is moved to contact the base plate. A holding force is applied to the axle holder and is larger than the adjustment force or applied as well as it. The actions of the forces are in the cylinder adjustment direction, to hold the abutment and the base plate against each other.

The US 51 81 468 A describes a device for adjusting two rotating Cylinder, a stop limiting the travel of a cylinder against the Recording the cylinder is turned on.

The invention has for its object a method for adjusting a roller To create printing press.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention consist in particular in the compact Construction of the device. The diameter of each device is the same or preferably smaller than the diameter of the cylindrical shell of the color or Pan roll. Accordingly, when using several such devices side by side, e.g. B. on two adjacent inking rollers with attached rider roller as third roller - whereby all rollers are adjustable - no obstructions to one another to fear through these devices.

By a preselectable force, e.g. B. generated by a linear motion actuator - such as B. a motor for linear movements (cylinder with piston); Piezoelectric actuators, Electrochemical actuators etc. - gaseous, liquid medium or electric current, a preselectable contact pressure of the inking or dampening roller to neighboring ones Allows rolling safely. This setting is reproducible, i. H. Flattening one Rubber coverings of a dampening or inking roller (roller strips). I.e. the so-called "color or Dampening roller strips "can be kept constantly wide (flattening one Rubber covering of a dampening or inking roller).

Influencing by a so-called "channel runout" when the ink or dampening roller of a gap is rolled over on other rollers is not possible because the locking pressure P _F , and thus the locking force F _F with which the roller pin of the inking or dampening roller is held, can only be set several times larger than the contact pressure P _A and thus the contact force F _A with which the roller with its coating is pressed against a jacket of an immediately adjacent cylinder or roller.

It is a quick presetting of the rollers, also to compensate for Changes in diameter during production and / or changes in shore hardness of the rollers possible. As a result, the set-up times are practically negligible. Your remote setting is e.g. B. possible centrally from a machine control center.

The roller (s) can be held as "clamped" during the entire running time. This ensures that the rollers run very smoothly even while the printing machine is running, since an application of a pinching effect (blocking effect) means that vibrations in the roller journals / axes are not "rocking". By applying a holding pressure P _F or a locking force F _F to the directional cylinder that is several times greater than the setting pressure P _A or adjusting force F _A , the result is that a stop that follows the adjustment is so strong against a frame-mounted counter bearing is pressed that in the prevailing operating state of the roll adjustment, an unintentional movement of the set roll in and against the roll adjustment direction E is not possible.

A first roller or cylinder 01 of an inking or printing unit of a printing press is pivoted or fixed in side frames.

On it is a second roller 02 with a jacket 05 made of elastic (rubber-elastic or elastomeric) plastic, e.g. B. rubber or other rubber-like material a movable, e.g. B. bowl-shaped pin receptacle 03 or axis receptacle (in others also called "recording" for short).

The roller 02 is on both ends on a bearing axis 06 by means of sliding or Rolling bearing rotatably. Each bearing axis 06 is on a pin receptacle 03, for. B. attached by means of a screw 04 so that it cannot rotate. This happens e.g. B. by Screw in the screw 04 through a hole in the pin holder 03 and in a threaded hole in the pin 06. Of course, instead of Bearing on axes 06 A bearing on materially attached to roller 02 Pin 06 may be provided. However, there would then have to be storage on reception 03 to be ordered.

The bearing journals 06 of the roller 02 are cup-shaped in the respectively associated one Pin holder 03 attached.

The pin receptacle 03 is attached to a positioning plate 09 (e.g. welded on). This has a plurality of guide bores 11. In addition, there is a drive 24 (actuator) provided that is attached to it via its housing 05.

The drive 24 (actuator 24) can be used as a motor for rotary movements, such as. B. electrical, Pneumatic or hydraulic motor - but also as a motor for straight-line movements - like z. B. working cylinder with piston, linear motor, DC magnet, piezo actuator, electrochemical actuator.

It is important here that the actuator 24 can be set in terms of torque or power or output power is.

In the exemplary embodiment, the drive 24 is designed as a motor for linear movement. A double-acting working cylinder 27, to which gaseous gas can be applied, is used for this purpose or liquid medium (e.g. air or oil). The housing 05 of the drive 24 (actuator), z. B. a working cylinder 27, with its piston rod side 50 pointing down, on a top 20 of the plate 09 attached.

A piston rod 29 of a piston 28 of the working cylinder 27 protrudes through a bore 10 of the plate 09 downwards. Its end 15 is on a horizontal leg 25 (= Base plate 25) of a bracket 14 rigid or articulated.

A vertical leg 16, i.e. a base plate 25 of the bracket 14 is in each case an inside of a machine frame 08 of a printing unit or inking unit adjustable in and against vertical direction and fixable attached.

However, the device referred to collectively as "device for setting 26" can also be arranged within an opening (hole) in the side frame 08 and in itself support him.

For vertical adjustment of the device 26 is used in the machine frame 08 and Lockable eccentric bushing 23 with the eccentricity "e". The eccentric bush 23 has an external hexagonal adjustment head 22 via which a rotary movement is initiated on the eccentric bushing 23 by means of a key.

In addition, a device for fixing 17 the eccentric bushing 23 is provided. You can e.g. B. from ratchet screw 18 with a smooth shaft 30 and threaded part 19th consist. Threaded part 19 is with an internal thread 21 of a bore of the eccentric 23 engaged. The locking toothed screw 18 can be securely tightened in such a way that not the set position of the leg 16 and thus the position of the device 26 can change more. The (fastening) leg 16 is on its on the Diameter of the shaft 30 matched bore threaded onto the shaft 30. to For additional security, a locking tooth screw 76 can be provided, a slot in the machine frame 08 through in a threaded hole in Side frame 08 adjacent (fastening) leg 16 is screwed. hereby the leg 16 can be secured against the inner surface of the machine frame 08 be pressed.

On a top 42 of the base plate 25 are a plurality of vertical aligned guide rods 12 attached, for. B. welded. The Guide rods 12 have the task of interacting with on their cross section closely matched guide bores 11 of the positioning plate 09 along the guide rods 12 to enable and thus a change in the distance 35 between the base plate 25 and Reaching plate 09.

On the underside of the positioning plate 09 is at a right angle with its upper end downward rod 33, e.g. B. welded with external winch 44. His lower free end 45 projects freely downward through a bore 40 in base plate 25 (= Mounting leg) of the bracket 14, z. B. 20 mm.

On the free end 45 of the rod 33 is a stop 32, for. B. in the form of a disc threaded. This stop 32 is in relation to the underside 31 of the base plate 25 along the rod 33, e.g. B. threaded rod, distance adjustable. This can e.g. B. How shown in the embodiment, by the design of the stop 32 as one drivable adjusting nut 32 happen on the thread of the free end 45 of Rod 33 can be rotated clockwise and counterclockwise.

However, other solutions would also be conceivable. Instead of the stop 32 along the Free end 45 to move, the stop 32 at the free end 45 of the rod 33 be attached in a rotationally fixed manner and the rod 33 can be moved back and forth and locked be arranged. This could e.g. B. happen in such a way that the rod 33 with an external thread 44 is provided with a thread in a bore in the Position plate 09 is engaged. One end of the Rod 33 is reversible with a clockwise, counterclockwise drive, z. B. one Electric motor or pneumatic motor, e.g. B. connected stepper motor, but also the use a servo valve would be conceivable.

When using a disc-shaped stop 32 (FIG. 1), which has a Thread connection back and forth along the free end 45 of the (threaded) rod 33 can be moved, the stop 32 is driven.

For this purpose, the stop 32 z. B. even with a first ring gear 36 or Gear 36 provided. The toothing of the ring gear or gear 36 is also available a toothing of a drive gear 37, which, like the stop 32 also, is arranged below the base plate 25. The tooth width of the drive gear 37 is a multiple of the tooth width of the teeth of the ring gear 36.

This ensures that the stop 32 as a hub with the ring gear or as a part Gear 36 of gear 36 is formed along an intended travel path can be moved without the tooth engagement of the teeth of the gear 36 and Drive gear 37 is canceled.

The drive gear 37 is equipped with a drive 39 (actuator) which can be reversed in the direction of rotation, z. B. Motor for rotary motion (electric, step, hydraulic, pneumatic motor) over whose drive shaft 38 is connected non-rotatably.

The drive 39 is z. B. on the top 42 of the base plate 25 - that is in the space between the base plate 09 and base plate 25 - the base plate 25 or attached to the underside 31 thereof. The drive shaft 38 with the drive gear 39 protrudes a hole in the base plate 25 down out of it.

1, the stop 32 - in this case as the hub of the Gear 36 are rotated by the drive gear 37. Depending on the direction of rotation of the Gear 36 and thus the adjusting nut 32, it moves along the thread 44 of the Rod 32 on the bottom 31 of the base plate 25 or away from it. He can in any distance from the bottom 31 on the rod 33 on and held, but also the bottom 31 are stopped touching.

Depending on the arrangement, the stop 32 can not only on the base plate 25, but also support on the positioning plate 09.

1 and 2, a practically infinitely variable contact pressure-dependent contact pressure of two immediately adjacent rollers 01 and 02 is possible, depending on the contact pressure F _A applied to the receptacle 09. In this case, the roller 02 to be adjusted - and thus the receptacle 06 - covers at least one adjustment path up to a final adjustment position 69 of the roller 02. A measure of the contact pressure-dependent contact pressure is e.g. B. the indentation 07, in z. B. highly elastic or rubber-elastic or elastomeric jacket 13 one of the two rollers 01; 02 or the width of the so-called roller strip of the rollers 01; 02. At least one of the two rollers 01; 02 must have a rubber-elastic or highly elastic or elastomeric cover (jacket 13).

To the pressure between the two rollers 01; 02, at least one of the two rollers 01; 02, the other roller 02; 02 can be arranged on and off, that is to say can carry out a stroke 95 which is greater than the maximum achievable depth of the indentation in the casing 13 (minimum adjustment path). When rollers 02 and 01 are engaged, the jacket 13 is compressed between them by the dimension (r _B -r _A ), is equal to the indentation depth 07 and results in the partially pressed-in jacket 96.

The roller 02 is adjusted via its two bearing axles 06 (only one ) Shown. Flying storage would also be possible, so that one per roller 02 would only have one bearing axis or journal 06.

Therefore, a device for setting 26 an inking or dampening roller 01; 02 with a pin receptacle 03 with an available stroke 95 and a pre-adjustable positioning force F _A and holding force F _{F is} an advantage.

The limitation of the stroke 95 of the roller 02 to be adjusted is infinitely adjustable. This is done by changing the position of the stop 32 in the longitudinal axis direction on the rod 33. In other words, the position of the stop 32 of the setting plate 09 in relation to the base plate 25 fixed to the frame can be set and locked.

Before the roller 02 can be placed against the roller 01 with a preselected pressure P _A or force F _A , the stop 32 (adjusting nut) must be at a sufficient distance 43 from a stop surface 31 fixed on the side frame - in this case the underside 31 of the base plate 25 - brought (see dashed gear 36 and stop 32 in Fig. 1). For this purpose, the gear 36 with the stop 32 from the drive 39; 37 driven so that it has moved along the thread 44 of the rod 33 from the stop surface 31 to a preselectable distance 43, which in this case would correspond to the maximum achievable stroke 95.

During the process just described or after its end, the drive plate 24 with the preset setting force F _A moves the setting plate 09 with the pin receptacle 03 away from the base plate 25 which is fixed directly or indirectly in the machine frame 08. Of course, this movement also follows the roller 02 with its z. B. rubber-elastic jacket 13 in the direction of the roller 01. Roller 02 with jacket 13 is moved with the preselected positioning force F _A until the jacket of the roller 01 is in contact until it is in balance with the reaction force (= positioning force-dependent adjustment).

The gearwheel 36 is then driven and the stop 32 is thus moved in the opposite direction of rotation until it finally strikes against the stop surface 31 with a torque or force that can be preset via the drive 39 and is slightly tightened. The drive 39 is immediately stopped and the setting pressure P _A or the setting force F _{A is increased} by the drive 24 by a multiple of F _A (z. B. quadruple), and thus a preset holding force F _F or holding pressure P _{F is} reached. The stop 32 is pressed or pulled even more against the stop surface 31 by the increased holding force F _F , because the drive 24 acts in such a way that the adjusting plate 09 and base plate 25 move towards one another. In this operating state it is practically no longer possible to change the center distance on the rollers 01 and 02 in the direction of the roller 01. The recording 06 is therefore blocked in its ability to move.

When the setting force F _{A is} readjusted or the roller 02 is switched off from the roller 01, the setting pressure / force P _A / F _{A is brought} to zero. Subsequently or simultaneously, the stop 32 is brought and stopped at a preselectable distance 45 to the stop surface 31 via the gear 36 now driven backwards by the drive 39; the contact pressure / force P _A / F _F or holding pressure / force P _F / F _F reversed in their direction. By this measure, the stop 32 finally reaches a sufficient distance 43 from the stop surface 31 and thus the roller 02 is turned off from the roller 01.

Another setting option would be "distance-dependent" employment. For this would first stop 32 at a preselected distance 43 to stop surface 31st brought.

Then the setting plate 09 with threaded rod 37, stop 32 and gear 36 by means of the drive 24 with preset force, for. B. holding pressure / force P _F / F _F until the base plate 25 fixed to the frame until finally the stop 32 strikes the stop surface 31. This holding pressure / force P _F / F _F is present during the entire operating time. If the roller 02 is to be switched off, the direction of the holding pressure or the holding force is reversed and the setting plate 09 is pulled in the direction of the base plate 25.

However, the version is also possible in which the stop 32 on parts - e.g. B. the Guide rod 12 - the base plate 25 is fastened movably and fixably, namely between the base plate 09 and base plate 25 or at one through the Guide bore 11 leading free end of the guide rod 12th

While the position of the stop 32 can be adjusted via the drive 39 (actuator), the Moving the positioning plate 09, the drive 24 (actuator) is provided. The drive 24 is in the Embodiment z. B. as a double-acting pneumatic or hydraulic cylinder 24 (Actuating cylinder 24) with the piston chamber connection 24 (4) and the piston rod chamber connection 24 (2) executed.

Port 24 (2) is connected to a by means of a pneumatic or hydraulic line 47 first branch connection 51 (2) of a first pneumatic or hydraulic Distributor 51 connected. A second branch connection 51 (FIG. 3) is either with a Piston rod chamber connection of another actuating cylinder connected or locked.

A supply connection 51 (1) of the first distributor 51 is by means of a pneumatic one or hydraulic line 34 with a connection 48 (4) of a first, the 5/2-way valve 48 connected, which serves as a "pressure" or "turn on" valve. A connection 48 (5) of the directional control valve 48 is by means of a pneumatic or hydraulic Intermediate line 60 via a connection 57 with a first ventilation line 65 connected.

Piston chamber connection 24 (4) of the actuating cylinder 24 is by means of a pneumatic or hydraulic line 62 with a first branch connection 49 (2) of a second pneumatic or hydraulic distributor 49 connected. A second Branch connector 49 (3) is either with a piston chamber connector connected to another actuator cylinder or closed.

A supply connection 49 (1) of the second distributor 49 is connected to a connection 48 (2) of the 5/2-way valve 48 by means of a pneumatic or hydraulic line 46 connected. A connection 48 (1) of the 5/2-way valve 48 is by means of a pneumatic or hydraulic line 70 via a connection 58 of a second pneumatic or hydraulic pressure feed line 64 (pipe or hose line) connected.

A first (access) connection 48 (3) is by means of a pneumatic or hydraulic Line 75 (pipe or hose line) via a connection 59 with a second Exhaust line 66 (pipe or hose line) connected.

An electropneumatic or electrohydraulic pressure control valve 78 is provided to supply the pneumatic (or hydraulic) cylinder 24 with compressed air or a hydraulic fluid for generating the contact pressure P _A , hereinafter referred to as "E / P pressure control valve" for short. This E / P pressure control valve 78 controls a z. B. him proportional pressure P _A.

The integrated electronics of the E / P pressure control valve 78 make a comparison between the set target pressure value and the actual target pressure P _{A of} the working line 73 (actual pressure value), which is detected by means of a piezoresistive pressure sensor 86.

A controller 87 generates a manipulated variable that controls a 3/3-way valve 90 via a clocked U / I converter 88 and a proportional solenoid 89, so that the preset "contact pressure" P _A at port 90 (A) of the 3/3 Directional control valve 90 is available. The working line 73 (pipe or hose) is connected at its first end to the connection 90 (A) of the directional control valve 90.

A second end of the working line 73 (pipe or hose) is connected to a connection 55 (4) a second 5/2-way valve 55 connected.

A gaseous or liquid fluid (from a fluid pressure source 79, via an inlet 92 (1) of a distributor 92) receives an operating system pressure P _B , which can also be the holding pressure P _F (e.g. 6-12 bar) (e.g. Air or hydraulic oil) via the first outlet 92 (3) of the distributor 92 to a connection 90 (P1) of the 3/3-way valve 90 of the electropneumatic (or hydraulic) pressure control valve 78. A second outlet 92 (2) of the distributor 92 is over a working line 72 (pipe or hose) with a connection 55 (2) of the second 5/2-way valve 55 (with two flow positions connections, two switching positions, actuation by proportional solenoid and return spring and detent position) connected.

A connection 55 (1) of the second 5/2-way valve 55 is connected via an intermediate line 84 the pressure feed line 64 connected. The connections 55 (5) and 55 (1) of the Directional control valve 55 are closed by means of closures 69 and 71.

At the connection 48 (1) is in the first switching position, the "holding position" (shown in Figure 2) of the second directional valve 55, a higher pressure, the "holding pressure" P _F , z. B. the system operating pressure of 10 bar. In the second switching position, the "setting position", of the second directional valve 55, the "setting pressure P _A " is present at the connection 48 (1). This is generally lower than the "holding pressure P _F ". "The setting pressure P _A " is can be adjusted to, for example, 0.1 to 8.0 bar and kept constant by means of the pressure control valve 78.

In a first position, the "holding position" of the 5/2-way valve 55, there is a flow made between terminals 55 (2) and 55 (1).

The higher "holding pressure P _F " now prevails in the feed line 64.

In a second position, the "setting position" of the second 5/2-way valve 55, flow is established between the connections 55 (4) and the connection 55 (1).
The lower "set pressure P _A " now prevails in the feed line 64.

The directional control valve 48 also has two positions. A second position, the so-called "Position" and the first position, the so-called "position" (shown in Figure 2).

In the "setting position" of the directional control valve 48, its connections 48 (4) and 48 (1) are switched to flow; likewise connections 48 (2) and 48 (3). The piston rod space of the actuating cylinder 24 is then, depending on the switching position of the directional control valve 55, either with the lower contact pressure P _A or the higher holding pressure P _F via the path 24 (2), 47, 51 (2), 51 (1), 34, 48 (4), 48 (1) and feed line 64 applied.

The piston chamber of the actuating cylinder 24 is here 24 (4), 46, 49 (2), 49 (1), 62, 48 (2), 48 (3) and exhaust line 66 are vented.

In the "setting position" it is achieved that the roller 02 via the setting plate 09 with preselectable and constant pressure P _A - z. B. 2 bar - is pressed onto a second roller 01. A flattening of measurable width or indentation depth 07 of or in the cover (es) of / in the elastomeric jacket 13 cylinder 02 is achieved. This can be changed, ie adjusted, depending on the applied pressure P _A.

In the "parking position", roller 02 is stopped by roller 01. Here, the second directional valve 55 is switched - flow between connections 55 (2) and 55 (1) - that the high operating pressure P _B , which can be the same as the locking pressure P _F , is on the feed line 64.

The directional control valve 48 is in the "shut-off position" (shown in FIG. 2). The connections 48 (2) and 48 (1) on the one hand and the connections 48 (4) and 48 (5) on the other hand are switched to flow. It follows from this that the full pressure P _F or P _B prevails in the piston chamber of the cylinder 24 and the setting plate 09 with the cylinder 02 attached to it is moved away from the cylinder 01 to a predetermined distance. The connections 48 (4) and 48 (5) are used for venting via line 60 and first vent line 65.

After completing this process, cylinder 01 is in the “roller down position”.

All drives and actuators such as drives 24, 39 and also 94 can be controlled from a central machine control station via a central electronic control device 52 (eg computer). In addition, the setpoints for the presettable pressures P _a and P _{F can be} set. The directional control valves 48, 55 are reversed in accordance with the specification of the "set" command from "set pressure P _A " to "set pressure P _F ". For this purpose, the electromagnets of the directional control valves 48; 55 connected via connections 52 (68) and 52 (67) and electrical control lines 67 and 68, respectively. Actual value output 81 is connected to control device 52 via an electrical connection line 81 and connection 52 (81) and setpoint input 82 is connected via an electrical connection line 54 and connection 52 (82). The voltage supply 56 to the control unit 52 takes place via its connection 52 (56). A sufficient number of displays of the set target pressure and the actual pressure are provided at the central machine control center.

In addition, before the locking pressure P _F is automatically applied, the drive 39 is acted on in such a way that the stop 32 bears against the stop surface 31 or 42 or 20 assigned to it and switches off when a preselected torque or motor current is reached, for example. The drive 39 can be controlled by the control device 52 via the electrical feed line 41 in clockwise and anti-clockwise rotation. In this way, the blocking of the base plate 09 can be released when the adjusting force F _{A is} adjusted or when the command “roll down” is carried out.

It is within the scope of this invention that the generation of the setting force F _{A is} not limited to pneumatic and hydraulic drives 24. Piezoelectric and electrochemical actuators are also suitable. As shown in FIG. 3, the upper side 42 of the base plate 25 serves as an abutment and the lower side 83 of the positioning plate 09 serves as a force application for the actuator 94. The actuator 94 is connected to the control device 52 for its control via an electrical connecting line 61.
For the purpose of measuring the positioning force F _A actually exerted by the actuator 94 on the roller 02, a pressure measuring device 84 with its electrical connection 85 is arranged on the setting plate 09. It is used to measure the actual F _A value. The pressure measuring device 84 can consist, for example, of strain gauges in Wheatstone bridge circuit. Your bridge branches are then applied to the top 20 and the bottom 83 of the positioning plate 09 in the vicinity of the axis mount 03. The setting plate 09 is blocked and unblocked via a stop 32 as described above in the other exemplary embodiments.

It should be repeated that a device 26 for adjusting the contact pressure F _A or locking force F _F per bearing journal or bearing axis 06 is provided for the roller 02 to be adjusted in the case of on-the-fly storage. In the case of an adjustable roller 02 which is not mounted on the fly, two devices 26 are provided which can be preset and / or switched on individually or jointly, so that they act on one or both axle receptacles 06 per roller 02.
