    description
    The invention relates to sealing strip holder for suction rolls.
    A suction roll, which is used for dewatering web material, for example in paper machines, has a roll jacket provided with openings and at least one suction box inside. The suction box is fixedly mounted inside the suction roll with the perforated roll shell rotating around the suction box. In order to seal the suction box against the roll shell, the latter has laterally sealing strips which seal the interior of the suction box from the remaining volume of the suction roll, specifically in the longitudinal direction of the suction roll. In the circumferential direction of the suction roll, the suction box is delimited at both ends by a format limiter and sealed against the roll shell.
    A particular challenge in the construction or operation of suction rolls is the supply of lubricating water for the reduction of heat generation and wear on the sealing strip.
    From WO 2013167656 Al it is known to install a spray tube in front of each sealing strip used in the suction roll, wherein each spray tube has its own supply line. The same is already known from DE 1005825 B of 1957. A disadvantage of the introduction in front of the sealing strip by means of additional spray pipes is the additional space requirement in the suction roll and the increased installation effort. A disadvantage of the known suction pipes within the suction zone is that they reduce the suction zone on the one hand and thus reduce the efficiency of the suction roll and on the other hand the vacuum prevailing in the suction zone sucks off a considerable amount of the lubricating water before it reaches the sealing strip.
    From WO 2013167656 Al it is further known to provide the supply of the lubricant in the sealing strip, which can also be found in WO2014026913 (A1). The supply of the lubricating water in the sealing strip is nach¬teilig for several reasons. Firstly, the friction surface of the sealing strip is reduced by the openings of the lubricating water supply, secondly wear the openings of the lubricating water supply zuse¬hends, third, designed as a wear part sealing strip in the production consuming and thus more expensive, fourth, the holder itself is more complicated, fifth is in the sealing strip holder movable sealing strips, as is common in the prior art, the transition from the sealing strip holder in the sealing strip difficult, whereby the assembly and sealing of the lubricating water system is complicated, sixth can the lubrication or the openings in the sealing strip by Ver Contaminants, fibers or chemicals, which would cause a local increase in wear and temperature, which in turn can lead to damage to the sealing strip or roller.
    The object underlying the invention is to make the introduction of the lubricating water in a simple, space-saving and targeted.
    According to the invention, it is provided as an improvement over the prior art to integrate the lubricant supply in the Dichtleis¬ holder.
    As a result, the lubricating water can be very close to the friction surface, so that surface with which rubs the sealing strip on the roll shell, introduced and the space required compared to a mounted in front of the Dicht¬leistenhalter spray tube can be reduced. In addition, the amount of lubricant can be reduced by the targeted introduction close to the sealing strip, whereby advantageously the otherwise enormous water consumption of the sealing strip is lowered. Compared with a lubricating-water system which is integrated into the sealing bar, there are inter alia the advantages that the friction surface is not reduced by the openings of the lubricating-water supply and that the sealing strip has a simpler construction.
    The device according to the invention thus consists of a Saug¬walze, inside which a suction box is mounted, which is laterally bounded by sealing strips. At least one sealing strip is associated with a lubricating water supply, which, viewed in the running direction, introduces lubricating liquid in the direction of the inside of the perforated jacket of the suction roll in front of the sealing strip, the lubricating water supply being integrated into the sealing strip holder. Each sealing strip preferably has an actuator, by way of which the setting pressure of the sealing strip on the inner lateral surface of the suction roll can be changed. The view in the direction of the second, rear sealing strip preferably additionally has a second actuator on which the opening angle of the gap between the sealing strip and Saugwalzenmantel is changeable. The second, rear sealing strip, viewed in the direction of travel, preferably has an electroacoustic transducer which is preferably integrated in the holder of the sealing strip and thus protected from moisture. In the sealing strips, temperature sensors are preferably provided which, in addition to the temperature measurement, preferably also serve for wear measurement. It is preferable to process the data of the sensors in a miniserver and to drive the actuators through the miniserver. A mini server is a miniaturized data processing system with input and output modules and possibilities for digital communication, in particular for wireless communication with input and output devices and other data processing systems of a network.
    Preferably, there is a flow sensor in the lubricant supply or in the lubricant feed line which is in data communication with the mini server to monitor, in real time, the amount of spray water used. to eat. The flow rate is preferably controlled or controlled by the Miniser¬ver, for example by adjusting at least one valve.
    In a preferred method according to the invention, it is proposed to measure the temperature of the sealing strip in order to optimize the use of lubricating fluid, and to measure the lubricating water consumption. to control or regulate the amount of lubricating water as a function of the measured temperature. For this purpose, the temperature can be measured at one or more points of the sealing strip and the amount of lubricating water introduced over the length of the sealing strip can be uniformly high in each region of the sealing strip.
    If the temperature of the sealing strip is measured in several areas of the sealing strip, a local temperature profile in the sealing strip can also be detected. Advantageously, the amount of lubricant introduced can be controlled or regulated separately at individual regions of the longitudinal flow of the sealing strip, so that in the case of local heat generation in the sealing strip, lubricating water is introduced in the affected area. As a result, the introduction of lubricating water is also washed away on the Dichtleisteanhaftendes material can be reacted to caused by such impurities temperature increasesausem the adhering material is washed away by increasing the lubricating water flow.
    Since the heat in the sealing strip is formed by friction on the inner circumferential surface of the suction roll and the lubricating water reduces this friction, so exactly the required Schmierwassermen¬ge be introduced, which is necessary to keep the friction and thus the wear low. For the method just described, it is necessary to detect the temperature of the sealing strip, as close as possible to the surface with which the sealing strip rubs against the inner circumferential surface of the suction roll. For this purpose, it is advantageous to mount the temperature sensor in the interior of the sealing strip, as known from DE 102007027688 A1. The distance of the temperature sensor DE 102007027688 A1 to said surface must be so high that they are still integrated in the material of the sealing strip until the maximum permissible wear is reached.
    As an improvement according to the invention, it is proposed to integrate a plurality of temperature sensors into the sealing strip, the temperature sensors being inserted or integrated into the sealing strip at different depths. It is particularly advantageous that the temperature sensors can also be used for wear monitoring or measurement. This is done by breaking the temperature sensors as soon as they are no longer protected by the material of the sealing strip and wear on the suction roll.
    Preferably, a plurality of such temperature sensors, which are offset in depth, are always combined in a sensor unit, wherein a plurality of such sensor units are preferably mounted over the longitudinal direction of the sealing strip. As a result, the local temperature profile in the sealing strip and the local wear in the sealing strip can be monitored or these data can be transmitted to a controller or regulator. The lubricating water or the lubricant can actually be water or another liquid, in particular re may be added to the water other liquids or additives.
    The invention is illustrated by means of drawings:

    In Fig. 1, the sealing strip 1.1, 2.1 according to the invention with in¬ integrated temperature sensors 6.1 is shown. In this particularly preferred embodiment, sensor units 6 are integrated in the sealing strip 1.1, 2.1, with each sensor unit 6 having four temperature sensors 6.1. With regard to the upper surfaces, ie the friction or friction surface of the sealing strip 1.1, 2.1, the temperature sensors 6.1 have different distances. The distance between two consecutive temperature sensors 6.1 is for example 2 mm. The sensor units consist of a printed circuit board 6.4, temperature sensors 6.1, a microchip 6.2 with integrated radio module and a power supply by means of battery 6.3. The employment of the sealing strip 1.1, 2.1 on the rotating roll shell 3 causes friction and thereby a rise in temperature on the sealing strip 1.1, 2.1. This temperature change brings about a change in resistance to the temperature sensor 6.1 positioned on the printed circuit board 6.4, the temperature being determined from the voltage change caused thereby by the programmed microchip 6.2. If a temperature sensor 6.1 is ground through, ie destroyed, a signal interruption occurs. As a result, the microchip 6.2 is able to calculate the exact sealing strip wear due to the signal interruption of the individual temperature sensors 6.1.
    Outside the suction roll, a mini server with radio module is positi¬oniert, the data from the sensor units 6 via radio emp¬fängt. The mini server is preferably connected to a network and the data can be visualized via an output device such as, for example, a computer, tablet computer, laptop or mobile telephone.
    The sealing strip 1.1, 2.1 has at least one sensor unit 6, the sealing strip 1.1, 2.1 preferably has a plurality of sensor units 6 in order to be able to measure the temperature at a plurality of points of the sealing strip 1.1, 2.1.
    In Fig. 2, an inventive sealing power system 1 is shown, which is preferably seen in the direction of movement of the roll shell 3 as the first sealing strip system 1 of a suction box 4 is used. The sealing strip system 1 consists of a sealing strip 1.1 which is movably received in the groove of the sealing strip holder 1.2. In the groove is located below the sealing strip 1.1 designed as a pressure hose Anstell¬ hose 1.3. Prior to the sealing strip 1.1, the sealing strip holder 1.2 is provided with a lubricating-water system which has spray nozzles 1.4, via which the lubricating water is introduced by a spray tube 1.5 preferably integrated in the sealing strip holder 1.2. At least one sensor unit 6 is preferably integrated or inserted into the sealing strip 1.1. By means of the pressure in the adjustment hose 1.3, the contact pressure with which the sealing strip 1.1 is pressed against the inside of the roll shell 3 can be changed.
    In Fig. 3, a sealing system according to the invention is shown ge 2, which preferably in the direction of movement of the suction roll ge as a second sealing strip system 2 of a suction box 4 is used. The sealing strip system 2 consists of a sealing strip 2.1 which has a web along the lower front edge, which is movably received in the groove of the sealing strip holder 2.2. In the groove is below the slope of the sealing strip 2.1 Anstellschlauch 2.3. In front of the sealing strip 2.1, the sealing strip holder 2.2 is provided with a lubricating water system which has spray nozzles 2.4, via which the lubricating water is introduced through a spray tube 2.5 preferably integrated in the sealing strip holder 2.2. Preferably, at least one sensor unit 6 is integrated into the sealing strip 2.1 used. About the pressure in Anstell¬ hose 2.3, the Anstelldruck with which the sealing strip 2.1 is pressed in the front region against the inside of the roll shell 3, can be changed. The sealing strip 2.1 has a curved upper surface, so that the upper surface rests in its front region on the roll shell 3 and forms a gradually increasing gap in the rear area with the roll shell 3. The width of this gap can be adjusted by means of a height-adjustable bar 2.7, which can move the rear end of the sealing strip 2.1 closer to or away from the roll shell 3. The height-adjustable bar 2.7is guided along an obliquely upwardly extending groove in a longitudinal direction of the sealing strip 2.1 sliding bar 2.6. The displaceable strip 2.6 can be designed as a slide, which is displaced by a motor driven Stellspin¬del in the groove of the sealing strip holder 2.2. A longitudinal displacement of the displaceable bar 2.6 causes the height-adjustable bar 2.7 to be pushed upwards along the groove. It is also conceivable to carry out the bar 2.6 in a fixed manner and to adjust it by longitudinal displacement of the height-adjustable bar 2.7 along the groove in height. Daviele possibilities exist to convert the rotational movement of a stepping motor into a linear movement of an actuator, it is generally stated that the distance of the rear end of the sealing strip 2.1 to the roll shell 3 can be changed by a motor and held in the respective position.
    In the sealing strip holder 2.2, a symbolically illustrated sound sensor 7 or a pickup is preferably mounted, which serves to measure the noise level at or after the sealing strip 2.1. The control method according to the invention provides that the opening angle of the gap between the sealing strip 2.1 and roll shell 3 is controlled such that the noise level is reduced to a minimum.
    As a generalization, it can be stated that, instead of the pressure hoses 1.3, 2.3, other adjusting devices known from the prior art can also be used on the sealing strip 1.1 and the front region of the sealing strip 2.1. Thus, for example, in addition to the pressure hoses, clamping devices may be provided to temporarily fix the sealing strip in position after achieving a stable, optimum operating condition. In addition, as known from EP 0943729 B1, an additional pressure hose may be present which acts in the opposite direction to the first pressure hose (positioning hose) on the sealing strip in order to "pull away" from the roll shell. to be able to.
    According to the invention it is also possible to provide a Verstellmechanismus for adjusting the sealing strip 1.1 and the front portion of the sealing strip 2.1, as it is used at the rear of the sealing strip 2.1. It can be dispensed with the use of a Anstellschlauches. Since, in contrast to the rearward region of the sealing strip 2.1, whose front region and the sealing strip 1.1 can be brought into contact with the roll shell 3, it is necessary to design the adjustment pressure in a controllable or controllable manner. The contact pressure can be regulated by a controllable holding torque of the motor, or be controlled indirectly by a fe¬derelastisches element, which is located between the actuating element and the sealing strip. If the sealant is already in contact with the roll shell, over a further adjustment of the actuator via the resilient elements, a force can be exerted with increasing deformation of the resilient element which presses the sealant against the roll shell. It is advantageous that the actuator can also be positioned so that there is a narrow gap between the sealing strip and roll shell.
    In Fig. 4, the structure of a suction box 4 mitzwei with two sealing strip systems 1, 2 according to the invention is shown schematically. The direction of movement of the roll mantle 3 is indicated by an arrow. The front first sealing strip system 1 seen in the direction of movement is designed according to FIG. 2, the rear second sealing strip system 2, as seen in the direction of movement, is shown in FIG. 3 executed. As can be seen in FIG. 4, the two sealing strip systems 1, 2 form the lateral boundary of the suction box 4. In the interior of the suction box 4, this results in a region 4.1 sealed off from the remaining interior of the suction roll.
    As symbolically represented, a pressure sensor 5 for measuring the negative pressure or vacuum in the sealed area 4.1 is located in the interior of the suction box 4. Alternatively, the determination of the negative pressure in the suction box 4 can also take place in or through the vacuum pump, which serves to generate the vacuum in the sealed area 4.1.
    The first sealing strip system 1 has a temperature sensor 16 for determining the temperature of the sealing strip 1.1, which is preferably embodied as a plurality of sensor units 6 integrated in the sealing strip 1.1 according to FIG.
    The second sealing strip system 2 has a temperature sensor 26 for determining the temperature of the sealing strip 2.1, which is preferably designed as a plurality of sensor units 6 integrated in the sealing strip 2.1 according to FIG. The second sealing strip system 2 also has a sensor for detecting noise, which is preferably designed as a sound sensor 7 integrated in the sealing strip holder 2.2.
    The first sealing strip system 1 has an adjusting mechanism for changing the position of the sealing strip 1.1, which preferably comprises a positioning hose 1.3. About the adjustment of the contact pressure of the sealing strip 1.1 and / or the distance between the sealing strip 1.1 and roll shell 3 is controllable and / or adjustable. The first sealing strip system 1 has a Schmierwas¬serzuführung, wherein the amount of introduced lubricating water controllable and or is controllable. The lubricating water supply is preferably designed as a spray pipe 1.5 integrated in the sealing strip holder 1.2.
    The second sealing strip system 2 has an adjusting mechanism for changing the position of the front region of the sealing strip 2.1, which preferably comprises a positioning hose 2.3. About the adjusting mechanism of the contact pressure of the front Be¬reichs the sealing strip 2.1 and / or the distance between the front region of the sealing strip 2.1 and roll shell 3 are controllable and / or adjustable. The second sealing strip system 2 has a second adjusting mechanism for changing the position of the rearward region of the sealing strip 2.1, which preferably comprises a stepping motor. The opening angle between the rear area of the sealing strip 2.1 and the roll shell 3 can be controlled and / or regulated via the second adjusting mechanism.
    The second sealing strip system 2 has a Schmierwasserzufüh- tion, wherein the amount of introduced lubricating water is controllable and / or controllable. The lubricating water supply is preferably designed as a spray pipe 2.5 integrated in the sealing strip holder 2.2.
    The control method according to the invention consists in a first variant in the detection of the negative pressure or vacuum in Saug¬kasten 4, wherein the contact pressure or the distance to Walzenman¬tel 3 of the first sealing strip 1.1 and the contact pressure or the distance to the roll shell 3 of the front region of Second sealing strip 2.1 are regulated so that sets that minimum An¬stelldruck or that maximum distance, which is zuläs¬sig to keep the vacuum in the desired thickness in the interior of the suction box 4 upright. The contact pressure or the distance can be varied in common for both sealing strips 1.1, 2.1, for example by the pressure hoses 1.3, 2.3 being subjected to the same pressure.
    A particularly advantageous feature of this control method according to the invention is that the energy requirement of the roller is minimized so that the vacuum is maintained at a minimum setting pressure, resulting in a high saving.
    It is also conceivable to regulate the setting pressure or the distance, if necessary, using fixable additional control provisions for both sealing strips 1.1, 2.1 separately, for example by pressing the more heavily worn bar less strongly than the even less worn bar.
    Preferably, in the first variant of the control method, a temperature sensor 16, 26 is also provided for detecting the sealing strip temperature of each sealing strip 1.1, 2.1. The amount of lubricating water used for sealing strip 1.1 is thereby controlled or regulated as a function of the measured values of the temperature sensor 16 and the amount of lubricating water used for sealing strip 2.1 is controlled or regulated as a function of the measured values of the temperature sensor 26. The regulation of
    Quantity of lubricant depending on the temperature of Dichtleis¬te 1.1, 2.1 is also without the aforementioned regulation of An¬stelldrucks used or advantageous.
    Particularly advantageous in this invention control or. Control method is that the water requirement is minimized and thus significantly less water is consumed than with conventional spray pipes.
    As an extension of the first variant, the noise level according to the invention is also measured in the second variant of the control according to the second sealing strip system 2 and, depending on the measured value, the distance of the rear region of the sealing strip 2.1 to the roll shell 3 and thus the opening angle of the gap zwi¬ sealing strip 2.1 and Roll shell 3 regulated so that there is a minimal noise level. This method can also be used separately from the methods described above, since the noise development on conventional sealing strips can amount to up to 110 dBA and can thus be hazardous to health.
    According to the invention, all measured values of all sensors are to be transmitted to a mini server, preferably wirelessly, in which the control and regulation rules are stored, which if necessary can be modified by a program or a user. The Miniserver determines from the measured values the manipulated variables required to control the actuators. Preferably, the miniserver is connected to a display and input device, in particular wirelessly, in order to display the operating parameters, or to display the operating parameters. to allow manual changes.
    Particularly advantageous in the subject invention is that the intelligent system for controlling all essential parameters within a suction roll, which are centrally monitored preferably by a mini server and can be changed either by the system or by the user in dependence on each other, ensures the most energy-efficient and quiet operation and one preventive maintenance. The
    System is based on sensors equipped with components such as particular sealing strip, pressure hose, sealing strip holder and spray pipe, which preferably via radio / WLAN constantly Informa¬tionen on the externally not visible and / or kontrollierba¬ren process and thus provide information in a unique form over the operating condition of the suction roll.

    If the two parts 1.2, 11 are fastened sufficiently tightly to one another, the feed channel 12, 13 resulting from the two recesses can also serve to supply the lubricating liquid.
    The supply part 11 can be designed with hollow chambers, wherein the supply of the lubricant to the spray nozzles 1.4, 2.4 or the openings 10 can take place exclusively in the feed part 11, as shown in FIG.

The sealing strip holder 1.2, 2.2 may advantageously also be designed as a hollow profile (for example extruded or extruded), wherein at least one chamber of the hollow profile serves to supply lubricating water, for which purpose this chamber is preferably closed at one end of the hollow profile and amanderen end to a supply line 14 is connected and the hollow profile is provided with openings 10 which lead into at least one used as a feed chamber of the hollow profile. The chamber may also extend only over a portion of the length of the opening of the hollow profile, for example by restricting the chamber on both sides by partitions inserted into the opening. The connection of the feed line 14 can be made through an opening in one of the partitions or through an opening from the jacket surface of the hollow profile into the chamber.
    Particularly preferably, the hollow profile in the pultrusion method (also called pultrusion or pultrusion called) manufactured, and is thus a fiber-reinforced plastic profile.
    As shown in FIGS. 5, 6 and 7, the sealing strip holder 1.2, 2.2 on its side facing the roll shell 3 preferably has a region running down to the sealing strip 1.1, 2.1, which joins together with the sealing strip 1.1, 2.1 forms a groove over which excess lubricating water can flow off in a controlled manner laterally in the longitudinal direction of the sealing strip holder 1.2, 2.2.
    As shown in the left part of the figure, an opening 10 can be supplied via its own feed channel 13, wherein each feed channel 13 has its own feed line 14, the flow rate of which is preferably controlled by a valve 15. can be regulated. The openings 10 can be widened in a slot shape in the longitudinal direction of the sealing strip holder 1.2, 2.2, so that the fluid jet emerging from the openings 10 covers a larger length region of the sealing strip 1.1, 2.1.
    As shown in the right-hand part of the figure, a plurality of openings 10 can be fed from a common feed channel 12, wherein the common feed channel 12 has a feed line 14 whose flow rate can be controlled or regulated preferably by a valve 15.
