Then, a plurality of scraper units 10 are swingingly mounted to a support shaft 4 disposed widthwise on the conveying surface 21, and a push-pressing mechanism 5 is supported on a bracket 6 fixed to the support shaft 4 on the back surface of an arm 12 having the scraper tips 11 attached to its one end and extending to the other end. The push-pressing mechanism 5 consists of a hollow elastic body 51 and pressurized fluid is supplied thereto from a pressure supply system 53. Pressure is added to a part of the tip 11 where belt 2 is worn and push-pressing force is reduced and a uniform push-pressing force as the whole is given. Thus, the adjustment of the push-pressing force for the belt 2 is not required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing deposits on a conveyor belt, which removes deposits such as transported articles adhering to the transport surface of the conveyor belt.

[0002]

2. Description of the Related Art A conveyor belt is not only a cause of belt meandering, damage, etc., but also falls over the entire length of the conveyor belt as the material adheres to the conveyor surface and is caught on the retan side and adheres to the retan roller. However, the processing work requires a great deal of labor.

Therefore, it is necessary to automatically remove the deposits on the conveyor belt.

Conventionally, as an adhering material removing device for adhering material such as an adhering material adhered to a conveyor belt conveying surface, a scraper chip (scraping blade) is pressed against the belt conveying surface to scrape off the adhering material.

Since the conveyor belt is worn during conveyance, the scraper chips are divided into a plurality of pieces in the width direction of the belt conveying surface in order to press the scraper chips tightly against the belt conveying surface according to the abrasion amount. It has a mechanism of pressing with an elastic material such as.

For example, as shown in FIGS. 13 and 14, the scraper chip 1 is divided into a plurality of pieces in the width direction of the conveyor belt 2 and is supported by the support shaft 4 through the rubber 3 (actually developed sho 60-). 85522 publication). A similar mechanism is disclosed in Japanese Utility Model Laid-Open No. 61-52619 (FIGS. 15 and 16),
Japanese Utility Model Publication No. 61-132313, Japanese Utility Model Publication No. 62-171.
519, Japanese Utility Model Publication 57-51219, Japanese Patent Application Laid-Open No. 62-215416, Japanese Utility Model Publication No. 1-174323.

Further, as a means for utilizing elasticity of a spring for a pressing mechanism, Japanese Utility Model Publication No. 61-122221 and Japanese Utility Model Publication No.
Japanese Patent Application Laid-Open No. 4-1415 / 1992 discloses a hollow elastic body instead of a spring.
No. 82212 is disclosed.

However, in the pressing mechanism using the elasticity of rubber or spring, when the abrasion of the belt progresses and the amount of displacement of the elastic body of rubber or spring increases, the pressing force of the scraper tip on the belt becomes weak. However, a residue of scraping off the adhered matter occurs. On the contrary, if the initial elastic force is increased according to the maximum amount of wear of the belt, the pressing force on the belt is increased and the belt is damaged.

Generally, the central portion of the conveyor belt in the width direction is more worn than the left and right side edge portions. Therefore, it is not possible to obtain a uniform pressing force in the belt width direction with the above-mentioned pressing mechanism using rubber or spring, and the worker regularly inspects it.
The pressing force of each scraper chip had to be adjusted by adjusting bolts based on experience and intuition.
Since the working environment is bad in a conveying line involving dust, an adhesion removing device that does not require adjustment work is required.

A device has also been proposed in which a piston supporting a scraper chip is erected vertically to a belt conveying surface and a lower end of the piston is supported by a hollow elastic body (Japanese Patent Laid-Open No. 18221/1992).
No. 2). This device can follow the change in the amount of wear in the belt width direction, but when the scraper tip gets caught on the belt seam or the damaged part of the belt, it cannot absorb the impact and the belt or adhered matter removing device May cause damage.

[0011]

SUMMARY OF THE INVENTION The present invention provides an adhering matter removing device which can stably hold scraper chips for a long period of time by following the amount of abrasion in the width direction of a conveyor belt, and does not require adjustment work during that period. Especially.

[0012]

An apparatus for removing deposits on a conveyor belt according to the present invention supports a scraper chip which is divided into a plurality of pieces so as to face each other in the width direction of the conveying surface of the conveyor belt so as to be elastically displaceable. Adhesive substances such as conveyed substances adhering to the conveying surface of the conveyor belt are removed. This device has a support shaft arranged in the width direction of the convey surface of the conveyor belt, a central portion swingably attached to the support shaft, a scraper chip mounted on one end, and a free end on the other end. A plurality of scraper units consisting of arms extending as ends, and a pressing mechanism arranged on the rear surface of the scraper unit for elastically displacing the units,
A bracket fixed to the support shaft so as to extend along the width direction of the transport surface and supporting the pressing mechanism;
The above-mentioned problem is solved by means including an adjusting mechanism that adjusts the rotational angular position of the support shaft about the axis.

The arm of the scraper unit may be V-shaped or I-shaped. The arm of the scraper unit may be I-shaped and the other end may penetrate the support shaft in a diametrical direction.

The pressing mechanism may be an elastic hollow body supplied with pressurized air. The elastic hollow body may be a continuous elastic tube or an elastic material bellows provided for each scraper unit.

The pressing mechanism may be a ram member provided for each scraper unit and supplied with pressure fluid.

[0016]

In the apparatus of the present invention, since the scraper units divided into a plurality in the width direction of the conveyor belt are attached to the support shaft independently of each other, the units can swing independently of each other. Since the pressing mechanism uses a pressurized fluid such as air or liquid, the pressure is evenly distributed, and when the belt is worn, pressure is added to the scraper unit in the part where the pressing force decreases, and finally Even pressure will be applied to the entire unit. Therefore, it is not necessary to adjust the pressing force of each scraper unit.
