Abstract

PROBLEM TO BE SOLVED: To provide a cleaner device capable of sufficiently removing deposition sticking to a flat belt with crosspieces. SOLUTION: At a scratching location A, a scratching member 18 of a scraper main body 23 comes into contact with the surface of a flat belt 4 and deposition of the flat belt 4 is scratched by the scratching member 18. Subsequently, crosspieces 10 are abutted on the scratching member 18, thereby the scratching member 18 is pressed down and the scraper main body 23 oscillates from the scratching location A to a retreating location B. When the crosspiece 10 passes and is away from the scratching member 18 just after the oscillation, the scraper main body 23 returns from the retreating location B to the scratching location A by a weight 21. Thus, deposition on the surface of the flat belt 4 is continuously scratched by the scratching member 18 because the scratching member 18 comes into contact with the surface of the flat belt 4 again.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner device for removing extraneous matter adhering to a belt of a belt conveyor with horizontal rails.

[0002]

2. Description of the Related Art A cleaner device 50 shown in FIG. 10 is of a scraping type conventionally used for a belt conveyor 52 which conveys by a flat belt 51. FIG. That is, the reversing section 5 is formed by the head pulley 53 of the belt conveyor 52 and the flat belt 51 wound around the head pulley 53.
4, and the cleaner device 50 is provided to face the reversing portion 54. The cleaner device 50 includes a main body frame 55 and a scraping chip 56 provided at the tip of the main body frame 55 and in contact (sliding contact) with the surface of the flat belt 51 to scrape off the adhered substance. The main body frame 55 is supported by a support shaft 57 parallel to the rotation axis of the head pulley 53.

According to this, when the head pulley 53 rotates, the flat belt 51 rotates in the direction of arrow M,
Thus, the transported object is transported. In the reversing section 54, since the chip 56 is in contact (sliding contact) with the surface of the flat belt 51, the adhering matter adhering to the surface of the flat belt 51 is scraped off by the chip 56. The surface of 51 is cleaned.

However, the cleaner device 50 is effective for the flat belt 51. However, when the flat belt 51 is provided with a horizontal rail 58 as shown by an imaginary line, the tip 56 has a horizontal rail. Therefore, the cleaner device 50 was not suitable for use because the interference with the cleaner device 58 interfered with the rotation of the flat belt 51.

On the other hand, as shown in FIG. 11, it is conceivable to use a vibration-type cleaner device 63. That is, the cleaner device 63 includes a polygonal cleaner rod 65 that is pressed against the flat belt 51 of the return path 64 inverted from the reversing portion 54 from the back side and is rotatable, and a support shaft 66 that supports the cleaner rod 65. It is configured.

According to this, when the flat belt 51 rotates, the cleaner rod 65 also rotates, and the flat belt 5 rotates.
The flat belt 51 is beaten and vibrated by the restoring action due to the tension of 1 and the surface deformation (irregularities of the surface) of the cleaner rod 65. Due to this vibration, the adhered matter adhering to the surface of the flat belt 51 is peeled off, so that the adhered matter can be also peeled off to the flat belt 51 provided with the horizontal rail 58.

[0007]

However, in the case of using the vibratory cleaner 63 as described above, if the conveyed object is once adhered to the flat belt 51 when the conveyed object is adhered. However, there is a problem that the film is not peeled sufficiently even when vibration is applied.

In addition, although not shown, there are a method of blowing air onto the flat belt 51 to remove the deposits from the flat belt 51 and a method of washing the flat belt 51 with washing water to wash away the deposits. However, in the method of blowing the air, the problem that the equipment cost is high, the problem that the separated adhered substance is scattered around, and furthermore, when a conveyed object having a bad smell is conveyed, the bad smell spreads widely. There is a problem. Further, in the method of cleaning with the above-mentioned cleaning water, there is a problem that the running cost is increased and a problem that the moisture content of the transferred object is changed.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaner device that can sufficiently remove the deposits attached to a flat belt with a crosspiece.

[0010]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a cleaner device for a belt conveyor with a horizontal rail according to the first invention is a cleaner device used for a belt conveyor with a horizontal rail in which a horizontal rail is provided on a flat belt. A scraper body is provided to face the reversing portion of the flat belt, and the scraper body includes a main body frame, and a scraping member attached to the main body frame and scraping off the adhered matter attached to the surface of the flat belt. And the scraper body includes:
The scraper swings between a scraping position at which the scraping member scrapes off the deposits on the surface of the flat belt and a retracting position at which the scraping member is pushed away by the horizontal rail of the inverted flat belt to allow passage of the horizontal rail. There is provided a return means which is freely supported and returns the scraper body from the retracted position to the scraping position.

According to this, when an object to be conveyed is conveyed by the belt conveyor with horizontal rails, the scraper body is located at the scraping position, and the tip of the scraping member comes into contact with the surface of the rotating flat belt, and Deposits adhering to the surface of the belt are scraped off at the tip of the scraping member and removed from the flat belt.

Thereafter, the horizontal rail passing through the reversing portion abuts on the scraping member by further rotation of the flat belt, whereby the scraping member is pushed away, and the scraper body swings from the scraping position to the retracted position. Immediately thereafter, when the horizontal rail passes and separates from the scraping member, the scraper body returns from the retracted position to the scraping position by the return means. As a result, the tip of the scraping member comes into contact with the surface of the flat belt again, and subsequently, the adhered substance attached to the surface of the flat belt is scraped off by the tip of the scraping member and removed from the flat belt.

As described above, even with a flat belt provided with a horizontal beam, the scraper body swings and the scraping member temporarily retreats from the horizontal beam to allow the horizontal beam to pass therethrough. Thereby, the deposit can be sufficiently removed from the flat belt.

In the cleaner device for a belt conveyor with horizontal rails according to the second invention, the scraping member is formed of an elastic body having a restoring force. According to this, when the horizontal rail passing through the reversing portion abuts on the scraping member and the scraping member is pushed away by the horizontal rail, the scraping member is elastically deformed and curved according to the pressing force of the horizontal rail. As a result, even when an excessive pressing force is applied to the scraping member, the scraping member is not damaged, and the scraping member is restored to the original posture when the pressing force is released by passing the horizontal rail. To contact the surface of the flat belt.

[0015]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. As shown in FIGS. 2 and 3,
The belt conveyor 1 with horizontal rails includes a head pulley 2, a tail pulley (not shown), a rubber flat belt 4 wound between the head pulley 2 and the tail pulley, and a rotational drive of the head pulley 2. A driving device (not shown), a plurality of carrier rollers 6 disposed between the head pulley 2 and the tail pulley and supporting the flat belt 4 on the transport path 5 side, and the carrier rollers 6 on the return path 7 side. It comprises a plurality of return rollers (not shown) that support the belt 4.

At both ends of the flat belt 4, a wavy flange 9 made of rubber is provided over the entire circumference. Further, the flat belt 4 is located between the two flanges 9 and made of rubber. A plurality of horizontal rails 10 are provided. Thereby, on the flat belt 4, both flanges 9 and each cross rail 1
A plurality of transport spaces 11 surrounded by 0 are formed.
The horizontal rail 10 is provided in a forwardly inclined posture in which the upper part is inclined toward the traveling direction M of the flat belt 4. Openings 13 are formed at predetermined intervals between the flange 9 and the horizontal rail 10.

The conveyor 1 is supported by a support frame 12, and the support frame 12 is provided with a scraping type cleaner device 14 and a vibration type cleaner device 15.

As shown in FIGS. 1 and 3, the scraper-type cleaner device 14 has a scraper main body 23 facing the reversing portion 16 of the flat belt 4, and the scraper main body 23 And a scraping member 18 attached to the main body frame 17 and in contact (sliding contact) with the surface of the flat belt 4 to scrape off the attached matter.

The main body frame 17 is formed in a rectangular frame shape and is supported between a pair of left and right support brackets 20 via a pair of left and right support shafts 19 so as to be vertically swingable. The two support brackets 20 are erected on the support frame 12.

The scraping member 18 is a rectangular flat plate made of nylon, which is an example of an elastic body having a restoring force.
It is detachably attached to one end of the main body frame 17 via bolts and nuts 24. The width of the scraping member 18 is substantially the same as the width of the horizontal rail 10.

The scraper body 23 has a scraping position A at which the scraping member 18 comes into contact (sliding contact) with the surface of the flat belt 4 at a substantially right angle as shown by a solid line in FIG. As shown in the drawing, the scraping member 18 is pushed down by the horizontal rail 10 of the inverted flat belt 4 and swings up and down between a retracted position B allowing the horizontal rail 10 to pass therethrough. In the horizontal position, and the inclined position at the retreat position B.

At the other end of the body frame 17, there is provided a weight 21 (an example of a return means) for returning the scraper body 23 from the retracted position B to the scraping position A by a downward biasing force due to weight. The support bracket 20 is provided with a stopper 22 that prevents the scraper main body 23 from swinging upward from the scraping position A when the other end of the main body frame 17 contacts the upper side from above.

As shown in FIGS. 2 and 3, the vibration-type cleaner device 15 is a polygonal cleaner which is rotatable by being pressed against the flat belt 4 of the return path 7 inverted from the reversing portion 16 from the back side. Rod 25 and this cleaner rod 2
5 is supported on the support frame 12 side.

The operation of the above configuration will be described below.
For example, when the sewage sludge or the like is conveyed by the belt conveyor 1 with horizontal rails, as shown in FIG. 2, the scraper body 23 of the cleaner device 14 is located at the scraping position A, and the tip of the scraping member 18 is moved at a predetermined speed. Since the surface of the flat belt 4 that rotates in the traveling direction M comes into contact (sliding contact) with the surface of the flat belt 4 from the horizontal direction, the adhering matter (for example, sewage sludge mixed into sewage sludge) adheres to the surface of the flat belt 4. It is scraped off at the tip of 18 and removed from the flat belt 4.

After that, as shown in FIG.
Abuts against the scraping member 18 from above, whereby the scraping member 18 is pushed and bent downward from the horizontal posture, and further, as shown in FIG. And swings from the scraping position A to the retracted position B.

At this time, as shown in FIG. 6, the horizontal rail 10 is in contact with the scraping member 18 and warps like a bow. Immediately thereafter, as shown in FIG. The recoil when the horizontal rail 10 passes between the scraping member 18 and the head pulley 2 and separates from the scraping member 18 rapidly restores the warped horizontal rail 10 to the original forwardly inclined posture. At this time, the adhering matter adhering to the horizontal rail 10 is separated from the horizontal rail 10 by the impact due to the repulsive force, and the scraper main body 23 swings from the retreat position B to the scraping position A by the biasing force of the weight 21. As shown by the solid line in FIG. 1, the stopper 22 comes into contact with the stopper 22 and stops at the scraping position A. As a result, the tip of the scraping member 18 comes into contact (sliding contact) with the surface of the flat belt 4 from the horizontal direction, and subsequently, the adhered substance attached to the surface of the flat belt 4 is scraped by the tip of the scraping member 18. It is removed from the flat belt 4.

The conveyed material such as sewage sludge conveyed to the reversing unit 16 is separated from the scraping member 18 when the horizontal rail 10 passes between the scraping member 18 and the head pulley 2 and moves away. It is discharged downward from between the horizontal rail 10 and the scraping member 18, and further discharged from the opening 13 (see FIG. 3).

As described above, the flat belt 4 having the cross rail 10
However, the scraper body 23 swings and the scraping member 18 is temporarily retracted with respect to the horizontal rail 10 to allow the horizontal rail 10 to pass therethrough. It can be sufficiently removed from the belt 4 and the cross rail 10.

Further, since the scraping member 18 is made of nylon, which is an elastic body having a restoring force,
As shown by the imaginary line in FIG.
When it is pushed down at 0, the scraping member 18 is elastically deformed and curved according to the pressing force of the horizontal rail 10. Thus, even when an excessive pressing force is applied to the scraping member 18, the scraping member 18 is not damaged, and when the pressing force is eliminated by passing the horizontal rail 10, the scraping member 18 returns to its original state. And makes contact (sliding contact) with the surface of the flat belt 4.

Further, with the rotation of the flat belt 4, the cleaner rod 25 of the vibrating cleaner device 15 is rotated, and the restoring action due to the tension of the flat belt 4 and the surface deformation (irregularities of the surface) of the cleaner rod 25 are caused. The flat belt 4 is beaten and vibrated, and the vibration adheres to the surface of the flat belt 4 so that the adhered substance is separated. Therefore, by using the scraper-type cleaner device 14 and the vibration-type cleaner device 15 together, In addition, it is possible to more reliably remove the deposits.

If the tip of the scraping member 18 is worn, the bolts and nuts 24 are removed, the scraping member 18 is removed from the main body frame 17, and the scraping member 18 may be replaced with a new one.

Hereinafter, another embodiment of the present invention will be described with reference to FIGS. The scraping member 18 is attached to one end of the main body frame 17 via a hinge 31 and is vertically swingable between a scraping position A and a reverse retreating position C obliquely above the scraping position A. ing. The hinge 31 is detachably fastened to the body frame 17 and the scraping member 18 via a bolt 32.

According to this, as shown in FIG. 9, when the flat belt 4 rotates in the reverse direction R, the main body frame 17 comes into contact with the stopper 22 and remains in the direction of the scraping position A. On the other hand, the scraping member 18 is pushed up from below by the horizontal rail 10 moving in the reverse direction R, and swings from the scraping position A to the reverse retreat position C via the hinge 31. Thus, the horizontal rail 10 smoothly passes between the scraping member 18 and the head pulley 2 smoothly.

As described above, when the conveyor 1 is reversely driven,
The scraper 18 is temporarily retracted to the reverse retreat position C with respect to the horizontal rail 10 to allow the horizontal rail 10 to pass therethrough.
Does not exert excessive force on the cleaner device 14 or the horizontal rail 10.

In each of the above embodiments, as shown in FIG. 1, the weight 21 is used as an example of the return means for returning the scraper body 23 from the retracted position B to the scraping position A, but a spring may be used. Good.

In each of the above embodiments, the scraping member 18 made of nylon is used, but it may be made of rubber. In each of the above embodiments, the tip of the scraping member 18 is brought into contact with the surface of the flat belt 4 at the scraping position A, but a minute gap is formed between the tip of the scraping member 18 and the surface of the flat belt 4. A gap may be provided so that the tip of the scraping member 18 does not contact the surface of the flat belt 4.

In each of the above-described embodiments, as shown in FIG.
Although it is provided in a forwardly inclined posture inclined toward (forward drive direction), the present invention is not limited to the forwardly inclined posture, and may be provided in a vertical posture.

In the above embodiments, as shown in FIG. 3, the main body frame 17 is supported between the pair of left and right support brackets 20 via the pair of left and right support shafts 19, but the pair of right and left The support bracket 20 is not limited to the shaft 19, and may be supported between a pair of left and right support brackets 20 via one support shaft that is long in the left-right direction (width direction).
