DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhering substance such as paper dust adhering to the surface of an endless belt-like body that circulates and runs on a loop-like path, such as a canvas used in a dryer part of a paper machine. And a strip-shaped scraper device for continuously removing the same during operation.

[0002]

2. Description of the Related Art FIG. 7 shows a general configuration of a dryer part 40 of a paper machine.

In FIG. 7, a dryer part 40 is composed of a group of dryers 41 which are divided into upper and lower tiers and are arranged in the traveling direction of the paper. The number of dryers 41 is determined depending on the type. Also, recent high-speed paper machines are composed of several groups of dryer parts.

The dryer 41 is composed of a cylindrical member having a length corresponding to the width of the paper to be produced. Since the inside of the dryer 41 is heated by pressurized steam or the like, the surface of the dryer 41 is kept at a uniform and appropriate high temperature. ing.

[0005] Each of the upper and lower dryers 41 has a plurality of guide rolls 42 appropriately arranged for each group.
The endless belt-shaped canvas 43 keeps a constant tension and circulates at the same speed as the rotating peripheral speed of the dryer 41 via a and 42b.

On the other hand, as shown by a broken line in the drawing, the continuously running paper 44 is continuously dewatered by a press part after a continuous paper layer is formed in a pre-process not shown, and is then dried by a dryer part as shown. 40 is introduced.

[0007] Paper 44 introduced into the dryer part 40
The dryer contacts the surface of each dryer 41, is covered with a canvas 43 above, receives a pressing force, and is dried while sequentially traveling through each dryer 41 at the same rotational speed as the rotational speed of the dryer 41.

[0008] The paper 44 sufficiently dried in the dryer part 40 is smoothed and polished on the surface of the paper 44 in a calendar 45, wound up in a specified amount as a roll paper 50 by a winder 46, and carried out for the next process. Is done.

During the above-mentioned series of steps, in the illustrated dryer part 40, the canvas 43 travels while keeping a strong pressing force while contacting the paper 44 in the drying process, and thus the canvas 43 is mixed in the papermaking material peeled off from the surface of the paper 44. It is inevitable that the pitch and tar or paper dust and the like generated from the surface of the paper 44 during the drying process (hereinafter collectively referred to as adhered matter) adhere to
In addition, since the canvas 43 is circulating, the amount of deposits increases with the passage of time, and is deposited on the surface of the canvas 43.

[0010]

As described above, the deposits deposited on the canvas 43 in the dryer part 40 are:
Occasionally, it adheres to the paper 44 in the process of being dried, thereby deteriorating the quality of the paper 44 and causing a large amount of adverse effects such as causing paper breakage.

Therefore, in order to use the canvas 43 continuously, it is necessary to periodically remove the adhered matter from the surface in contact with the paper 44 during operation or to take measures to prevent the adhered matter. As one of the adhesion preventing methods used, the surface of the canvas 43 during operation is
For example, there is a method in which a liquid release agent such as a silicon base is sprayed to make the transfer and adhesion of deposits from the surface of the paper 44 to the surface of the canvas 43 in a drying process surface-chemically difficult.

However, in this method, the release agent such as the above-mentioned silicon base has a high chemical cost, and a strong adhesive force of the adhered substance is often superior, and the effect is insufficient.

As another method, for example, at a position P in FIG. 7, a girder 47 is provided at right angles to the traveling direction of the canvas 43 as shown in FIGS. In some cases, a flexible string-shaped rope 48 is attached, and a wire mesh scraper 49 is connected to the rope 48 so that its free end flies along the running direction of the canvas 43.

The wire mesh scraper 49 is made of metal and has a flexible wire mesh shape. The wire mesh scraper 49 is brought into contact with the surface of the running canvas 43 and is attached to the surface of the canvas 43 by applying a pressing force by its own weight. The adhering substances are scraped off and trapped in the mesh of the wire mesh scraper 49.

However, in this type, when a substantially predetermined amount of deposits is captured on the mesh of the wire mesh scraper 49, the operation of the paper machine is stopped, the wire mesh scraper 49 is removed, cleaned, and then attached again. It is necessary, and this requires a great deal of time and labor. Further, the adhered matter is firmly adhered to and deposited on the used wire mesh scraper 49, and cleaning of this also requires much labor. Therefore, these operations lead to a decrease in the operating rate of the paper machine.

Further, when this wire mesh scraper 49 is incorporated in a mechanical arrangement as shown in FIG. 7, it cannot be installed on the canvas 43 corresponding to the lower-stage dryer 41 because it is arranged upward. There are drawbacks.

The present invention solves the above-mentioned disadvantages in the conventional example, and automatically and reliably removes deposits adhering to an endless belt that circulates and travels like a canvas during operation. It is an object of the present invention to provide a strip-shaped scraper device which can be effectively removed.

An adjusting bolt 36 is provided at the upper end of the arm 33, and the spring tension of an adjusting spring 37 attached between the tip of the adjusting bolt 36 and the lower end of the slide frame 12 can be adjusted.

That is, when tension is applied to the adjusting spring 37 by the adjusting bolt 36, the arm 33 rotates clockwise in the figure around the pin 24, that is, in a direction against running of the canvas 43. With the fixed stopper 38, the arm 33 is supported from the lower rear surface and positioned.

FIG. 6 shows the details of the blade 35 in a front view and a cross section. The blade 35 is adapted to move in a direction in which the scraper device 30 moves along the rails 3a and 3b on the contact surface with the canvas 43. It has a curved shape with a large curvature.

The details of the operation and the like in the present embodiment configured as described above will be described. First, the scraper device 30 is set so as to always wait on the drive device 25 side before operation.

In order to operate the scraper device 30, first, in a controller (not shown), the operating speed (the speed at which the scraper device 30 travels across the canvas 43) and the standby time (the scraper device 30 makes one reciprocation, Next, the time until one reciprocation) is set.

Next, when the start switch is turned on, the scraper device 30 moves toward the frame 1b while scraping off the deposits on the surface of the canvas 43 running at a predetermined operation speed.

When the scraper device 30 moves to the side end of the canvas 43, the cam follower 26 provided at the lower end thereof comes into contact with the cam 28b, and then the cam 28b pushes up the slide frame 12 via the cam follower 26, The blade 35 is positioned higher than the surface of the canvas 43.

Then, the standby position detection switch 32b operates to drive the drive device 25 in reverse, and the scraper device 30
Starts moving toward the start position.

At this time, the cam follower 26 is disengaged from the cam 28b at the side end of the canvas 43, and the tip of the blade 35 comes into contact with the surface of the canvas 43 with a predetermined pressing force, moves while scraping off the attached matter, and reaches the start position. Then, the standby position detection switch 32a operates and stops. After that, the operation is suspended for the previously set standby time, and the same operation is automatically performed again after the elapse of the standby time.

The cam follower 26 and the cam 28
a, 28b, the slide frame 1
Since the slide bearing 39 is inserted in the sliding surface of the guide shaft 8a and the guide shaft 8a, 8b,
Functions to enable smooth operation.

Each of the standby position detection switches 32a, 32a
The overrun detection switch 31 provided outside of the switch 2b is a switch for safety. If the standby position detection switch does not function, the overrun detection switch 31 is stopped by the operation of the overrun detection switch 31.

Next, the adjustment of the pressing force of the blade 35 on the canvas 43 will be described. First, the handle 11 shown in FIG. 3 is turned clockwise or counterclockwise so that the tip of the blade 35 contacts the surface of the canvas 43. As shown in FIG. 4, the gap (C) between the lower end and the slide frame 12 of the movable plate 7 is set to be a reference value (usually about 15 mm).

Normally, an appropriate tension is applied to the spring 16 in this state, and the tip of the blade 35 is set so as to contact the canvas 43 while maintaining an appropriate pressing force. In such a case, the handle 11 is operated in a direction in which the gap (C) increases. Conversely, when it is desired to reduce the pressing force, the handle 11 is operated so as to reduce the gap (C).

Further, beyond the range of the steering wheel operation,
When it is desired to change the pressing force, the adjusting screw 15 is adjusted to change the pressing force by adjusting the tension of the spring 16.

That is, the tip of the blade 35 is always in contact with the surface of the canvas 43 via the spring 16, and smoothly responds to irregularities and vibrations of the canvas 43 running at high speed, and always applies a constant pressing force. Deposits can be scraped off.

As shown in FIG. 4, since a rotational force acts on the tip of the blade 35 in the traveling direction of the canvas 43 due to the frictional force from the traveling canvas 43, the reaction force that overcomes this is adjusted by an adjusting bolt. At 36, the tension of the adjusting spring 37 is adjusted.

When an extraordinary force is applied to the tip of the blade 35 due to a large foreign matter entering the contact engagement portion between the canvas 43 and the blade 35, the arm 33 is moved by a curved arrow in the drawing. Attempts to rotate counterclockwise, which is the direction shown, causes the adjusting spring 37 to expand, and a restoring force acts.

However, this abnormal load is large,
When the rotational force is larger, the adjusting spring 37 gradually expands, and when the maximum extension point, that is, the upper support point of the adjustment spring 37 exceeds the line connecting the lower support point and the center of the pin 24, the spring of the adjustment spring 37 is released. On the contrary, the length is shortened, and acts in a direction to promote the rotation of the arm 33.

That is, the blade 35 automatically jumps up against an abnormal acting force exceeding a certain value from the canvas 43, and the arm 33 rotates and stops at the position shown by the dashed line in FIG. 43 and other devices will not be damaged.

The blade 35 is, as shown in FIG.
The blade 35 contacts the canvas 43, and the rails 3a, 3
Since the curvature is provided in the direction of movement along b, it is possible to move smoothly without being caught.

In addition, as a result of providing this curvature, the close contact portion between the blade 35 and the canvas 43 is shortened, and the adhered material peeled off from the surface of the canvas 43 travels on the canvas 43 from both sides of the contact portion of the blade 35. As a result, the water smoothly flows to the downstream side, and is captured in the saveall 23 arranged immediately downstream of the downstream side.

That is, by maintaining an appropriate curvature at the tip of the blade 35, no deposits are deposited on the back side of the blade 35, and the deposits can be easily and reliably collected and processed downstream. it can.

The present device is used not only for the upper canvas 43 but also for the lower canvas 43.
6 can be changed to a compression spring, for example, with a slight change in specification. In that case, the saveall 23 is usually unnecessary.

Although the present invention has been described with reference to the illustrated embodiments, the present invention is not limited to such embodiments.
It goes without saying that various changes may be made to the specific structure within the scope of the present invention.
