Abstract

The invention relates to a system (30) for changing a nozzle pipe (25) of an application device (20) with a replacement nozzle pipe (25’). The changing system (30) comprises a lever mechanism (32) and a locking system (33).

Description

The invention relates to a system for changing a nozzle pipe of an application device of a fiber web production line. More especially the invention relates to a system 5 according to the preamble part of claim 1.
As known from the prior art in fiber web producing processes typically comprise an assembly formed by a number of apparatuses arranged consecutively in the process line. Atypical production and treatment line comprises a head box, a wire section and a press section as well as a subsequent drying section and a reel-up. The 10 production and treatment line can further comprise other devices and sections for finishing the fiber web, for example, a sizer, a calender, a coating section. The production and treatment line also comprises at least one winder for forming customer rolls as well as a roll packaging apparatus. In this description and the following claims by fiber webs are meant for example paper and board webs.
In production of fiber webs, for example of paper or board webs, sizing is used to alter the properties of a fiber web by adding sizing agents (sizing medium), for example glue chemicals. Sizing can be divided to internal sizing and surface sizing. In internal sizing the sizing agent is added to pulp in the wet end of the fiber web machine before forming. In surface sizing the sizing agent is added onto the surface of 20 the fiber web directly or via a roll at the dry end of the fiber web machine at the dry end of the fiber web machine. The sizing of paper and board web typically utilize a separate sizer. In connection with sizers different kinds of sizing technology are employed in prior art arrangements, for example pond sizing technology or film-transfer technology or spray sizing technology.
In production of fiber webs, for example of paper or board webs, coating, especially the surface of a fiber web is formed with a layer of coating paste (coating medium) at a coating station followed by drying. The formation of a coating paste can be divided in supplying the coating paste onto the web surface, which is called the application of the coating paste, as well as in the adjustment of final amount of coat30 ing paste. The coating of paper and board web typically utilize a coating device - a coater. In connection with coaters different kinds of coating technology are employed in prior art arrangements, for example for example pond technology or filmtransfer technology or spray technology.
20176138 prh 14-10-2019
In WO publication 2006/058961 A1 is disclosed a method and system for processing a paper or board web or similar fiber web. In this method, a processing mixture is spread on the surface of the web with spray nozzles. In WO publication 02/072953 is disclosed an assembly for treating a moving web of paper of board with web treat5 ment substance which assembly comprises an application chamber located in at close vicinity of the moving web and facing the web and at least one linear nozzle array incorporating at least one nozzle for spraying the web treatment substance on the web. In Fl utility model registration 9401 is disclosed a device for treating a fiber web, which comprises an application device, in particular a spraying device, for ap10 plying treatment substance on a moving fiber wed.
In EP patent publication 1696075 is disclosed a coating machine for applying coating medium directly on the surface of a paper, paperboard or other fiber web or indirectly on the surface of a transfer element, for example applicator roll, which transfers the coating medium onto the surface of the fiber web. The machine has an 15 apparatus for pivoting and adjusting a functional unit, a hydraulic cylinder for pivoting the functional unit into an operating or readiness position and a service position. It is possible to set the operating or readiness position in the extended state of the hydraulic cylinder and the service position in the retracted state. One disadvantage in this kind of known system is that maintenance and cleaning of the functional unit 20 is difficult, especially during times when the web is running and it may also create a safety risk, especially if the machine is running due to the unsafe location of the functional unit in the service position.
In US patent publication 7029532 is disclosed a coating station which is intended for coating a web with a coating material. The station includes a load-bearing and 25 cross-directional frame extending substantially across the entire width of the web and applicator elements supported to the frame. The frame is arranged by at least one cross component formed out of sheet metal into a box-type structure, the cross component extending substantially across the entire width of the web and the cross component is attached to the end components by its end parts. This station further 30 comprises two nozzle units that have determined operating and maintenance positions. The maintenance position is located in machine direction further away from the web than the operating position. The nozzle unit in the maintenance position can also be serviced from the walkway even if the coating station is in use. One disadvantage of this known system is that maintenance maybe complicated as the nozzle 35 units even in the maintenance position are located above the machine and it is also disadvantageous that the nozzle pipe of the nozzle units cannot be replaced in this
20176138 prh 14-10-2019 maintenance position. Also, the walkways create further costs and in some cases, there is no room for a safe location of a walkaway near the nozzle units.
In EP publication 2784217 A1 is disclosed an arrangement in a fiber web production line comprising a nozzle pipe of sizing I coating equipment for applying coating or 5 sizing medium onto the fiber web, in which the nozzle pipe with the sizing I coating equipment is movable in cross-direction of the main running direction of the fiber web from operating position, in which it extends in cross-direction over the width of the fiber web, to the maintenance position at front or back side of the fiber web production line.
In EP publication 1011876 B1 a nozzle device with replaceable nozzle pieces comprising at least a nozzle device body with a nozzle orifice located therein, in which easy replacement of the nozzle pieces is attained by mounting them, e.g., on a band or plate and the nozzle device is provided with elements serving to retain the nozzle piece in place and elements sealing the nozzle piece against the nozzle device body 15 and with dedicated nozzle piece changeover means. In the publication is also disclosed a method for replacing a nozzle piece in the nozzle device of a spray coating station, which method comprises the steps of removing the nozzle piece from a nozzle device body and of replacing the removed nozzle piece with a new nozzle piece and wherein compression at the nozzle piece, which is being pushed against 20 the nozzle device body by the clamp member, is released by virtue of moving apart from each other the surfaces of the members that are adapted to compressively mate with those of the nozzle piece, the nozzle piece is transferred away from the gap between the device body and the clamp member and a second nozzle piece is transferred to the gap by virtue of transfer means, and the second nozzle piece is 25 locked to the nozzle device body by compressing the nozzle piece against the nozzle device body by means of the clamp member. One disadvantage of this known arrangement is that the assembly needs a large space and thus it might be difficult to find a suitable location for it in connection with the application system.
As the nozzles or nozzle units of spray coating or sizing units are as known attached 30 to pipes or corresponding frame parts that extend in cross direction over the width of the fiber web. The coating and sizing units can be located in different positions in the fiber web production line, for example at a belt-calender, or at a press section, or at a drying section comprising drying cylinders, or at a wire section, in many cases the moving of the nozzle pipe from the operating position to the maintenance posi35 tion for cleaning or for changing of the nozzles/nozzle units is difficult due to safety
20176138 prh 14-10-2019 reasons or due to space problems. Typically for example blockages of nozzle pipes or of nozzles, or for example deviations and I or mistakes in sprays of the nozzles cause long interruptions to productions due to need of washing pipes and/or changing nozzles and due to need of move part or parts of the system to a suitable location 5 for the operations needed and back to production setting. Often a larger assembly must be moved as hole to a maintenance location and thus heavy duty transfer equipment, for example cranes are needed.
An object of the invention is to create and system for changing a nozzle pipe of an application device of a fiber web production line for changing a nozzle pipe of an 10 application device of a fiber web production line in which the disadvantages of known systems in the art are eliminated or at least minimized.
An object of the invention is to provide a system for changing a nozzle pipe of an application device of a fiber web production line and in which the disadvantages of known systems and methods causing long interruptions in production due to mainte15 nance, repair and/or cleaning word of a part or parts of the application device are eliminated or at least minimized.
In order to achieve the above objects, the system according to the invention is mainly characterized by the features of claim 1. In dependent claims advantageous features are presented.
In this description by term operating position is meant the position of the nozzle pipe in which the nozzles/nozzle units are applying coating or sizing medium onto the fiber web or onto the roll, via which roll the coating or sizing medium is guided onto the fiber web, or in which position the nozzles/nozzle units are ready to apply i.e. the nozzle pipe is located over the fiber web or over the roll and extending in cross25 direction in relation to the main running direction of the fiber web. By term maintenance position is meant the position of the nozzle pipe in which its nozzles/nozzle units are cleaned or replaced or other maintenance work is directed to the nozzle pipe, to its nozzles or nozzle units to its other equipment etc. The nozzle pipe may naturally be located at the maintenance position even no active maintenance work is directed to it when it is not needed for operation i.e. for applying coating or sizing medium onto the fiber web or onto the roll. The maintenance position may comprise at least one position outside the production line area but it can also comprise more different positions for example for different kinds of maintenance work, for example a position for cleaning, a position for replacing or repairing of damaged or worn parts or components of the nozzle pipe or the nozzle pipe. In this description and claim
20176138 prh 14-10-2019 as pressing means for the treatment nips are referred as rolls but instead of rolls other type pressing means for forming the treatment nip known as such can also be used. By the term waiting position is meant position of a nozzle pipe or a replacement nozzle pipe, into which the nozzle pipe is moved from the operation position 5 to be moved to a maintenance position. The waiting position and the maintenance position can be the same position. The waiting position for a replacement nozzle pipe is the position, where the replacement nozzle pipe is located, while waiting to be moved to the operating position.
According to an advantageous aspect of the invention the system for changing a 10 nozzle pipe of an application device comprises with two main parts for changing the nozzle pipe with a replacement nozzle pipe, the main parts being a lever mechanism and a locking system, which provide for accurate positioning and for easy and fast replacement operation. Advantageously, the changing system comprises one lever mechanism at least for each end of the replacement nozzle pipe in longitudinal di15 rection. Advantageously the system further comprises at least two locking systems located in longitudinal direction of the nozzle pipe space apart.
According to an advantageous feature of the invention the system also comprises actuators for the lever mechanism for moving the nozzle pipes and the replacement nozzle pipes by the lever mechanism.
According to an advantageous feature of the invention the nozzle pipe in need of repair work in a repair shop or other location away from the production line can be detached and be replaced with another spare nozzle pipe thus avoiding further production losses due to the extended time needed for repair.
According to an advantageous feature of the invention the guide I relief rails of the 25 lever mechanism ease the mounting and carrying the load and provide for guidance of the nozzle pipe to the correct waiting position on the levers. The lever mechanism is advantageously automated for transferring the nozzle pipe from the waiting position to the operating position during the change. When the nozzle pipe has reached the operating position it is locked to its place by the locking system.
According to an advantageous example of the invention the lever mechanism of the system comprises two lever mechanisms with actuators, advantageously with pneumatic cylinders. One lever mechanism is located at each end of the nozzle pipe. As the nozzle pipe is supported from each end during the movement to the operating position, the nozzle pipes are advantageously pre-bent to compensate possible
20176138 prh 14-10-2019 deflection. Additionally, for each end of the nozzle pipe rotary connections are provided for decreasing the movements of the filling hoses of the spraying chamber and for preventing torsion of the change mechanism.
According to an advantageous example of the invention the locking system of the system comprises one plain bar with plungers and at least one actuator, for example a hydraulic cylinder. Advantageously each plunger is provided with adjustment means, for example adjustment screws to adjust the pressing force of pressing the nozzle pipe against the spraying chamber.
By the invention and its advantageous features several advantages are achieved: 10 one nozzle pipe is replaceable for maintenance, repair and/or wash, while another nozzle pipe is in operation and thus the production can continue almost without interruption despite the need of the maintenance, repair and/or wash operation/-s. When the spare nozzle pipe is taken to operation, the change time is less than 55 seconds by using the automatic change made possible by the invention. The change 15 can be done even without interruption in production. Advantageously the change is timed with the process to the stage when the fiber web running is from the bottom layers of the parent roll, which would be most likely rejected and thus minimum loss of production is achieved.
In connection with the invention size and weight of the nozzle pipe, which is to be 20 replaced, for which replacement pipes are provided, is minimized such, that material used for component is selected from lightweight materials, for example a composite material is advantageous. Advantageously the replacement nozzle pipes are manually carried and mounted, as each pipe advantageously weighs less than 50 kg and thus for handling the pipe manually only two persons are needed.
In the following the invention is explained in more detail with reference to the accompanying drawing in which
Figure 1 shows schematically an example of an application arrangement of a fiber web production line,
Figure 2 shows schematically an example of application device of the application 30 arrangement according to figure 1 as a cross-section view,

In the figures the corresponding parts and part components of the system are denoted by same reference signs unless otherwise mentioned. Some repetitive reference signs may have been omitted for clarity reasons.
In the example of figure 1 the application arrangement for a fiber web W comprises two treatment rolls 11,12 between of which a treatment nip is formed. The treatment rolls 11,12 are advantageously coating or sizing rolls 11,12 and the treatment nip is advantageously a coating or sizing nip. The system further comprises application devices 20 for applying the treatment substance via the treatments rolls 11,12 onto the surfaces of the fiber web W. The device 20 for applying the treatment substance comprises a changing system 30 for changing the nozzle pipe of the application device 20.
As shown in the example of figure 2 the changing system 30 comprises two main parts for changing the nozzle pipe 25 with a replacement nozzle pipe 25’: a lever mechanism 32 and a locking system 33. Two replacement nozzle pipes 25’ are provided and mounted onto a guide I relief rail 38 connected to the lever mechanism 32. The replacement nozzle pipes 25’ are located on the guide I relief rail 38, which eases the mounting and carrying the load and provide for guidance of the replacement nozzle pipes 25’ to the correct waiting position. The changing system 30 also comprises the lever mechanism 32 for transferring the replacement nozzle pipe 25’ from the waiting position to the operating position of the nozzle pipe 25 during the change. The movement paths of the nozzle pipe 25 and the replacement nozzle pipes 25’ are indicated in figure 2 by arrows.
The locking system 33 of the changing system 30 comprises one plain bar 39 with plungers 34 and an actuator 36, for example a hydraulic cylinder. Advantageously each plunger 34 is provided with adjustment means, for example adjustment screws to adjust the pressing force of pressing the nozzle pipe 25 against a corresponding contact surface 21 of a spraying chamber. The plunger 34 is turned by the actuator 36 to lock the nozzle pipe 25 to the operating position, as shown in the figure by corresponding arrow.
As can be seen from figures 2-4 the changing system 30 comprises two lever mechanisms 32 with actuators 37, advantageously with pneumatic cylinders 37. One lever mechanism 32 is located at each end of the nozzle pipe 25. As the nozzle pipe 25 is supported from each end during the movement to the operating position, the nozzle pipes 25 are pre-bent to compensate possible deflection. Additionally, for each end of the nozzle pipe 25 rotary connections 28, 29 are provided for decreasing the movements of the filling hoses for the spraying chamber and for preventing torsion of the lever mechanism 32. The changing system 30 comprises at least two locking systems with the plungers 34 located in longitudinal direction of the nozzle pipe spaced apart from each other. In the figures 2 and 4 the plungers 34 are in 5 opened position.
Advantageously the replacement pipes 25’ are manually carried onto support of the guide I relief rail 38 of the lever mechanism 32, as each pipe advantageously weighs less than 50 kg and thus for handling the pipe manually only two persons are needed.
Above only an advantageous example of the invention has been described to which examples the invention is not to be narrowly limited and many modifications and alterations are possible within the scope of the following claims.
