。Currently, the most popular type of belt conveyor is one that uses a rubber belt. Rubber belts are often used because they are cheap, and because they are easily elastically deformed and can constantly apply a certain amount of tension, they are less likely to loosen and reduce power transmission losses compared to other metal belts. For example, there are few people. In particular, for continuous long-distance transport over vast areas, rubber products are economically advantageous in terms of cost and maintenance, but they have the disadvantage of being fragile when transporting objects with sharp shapes. I was disappointed. For example, if a foreign object with a pointed foreign object of 8 sizes is dropped from a chute onto a belt comperator, the sharp part of the foreign object will pierce the belt or part of it will fall to ash. ) There is a claw.And when this foreign object is drawn to the lower part of the chute or the carrier roller that comes into contact with the elongated part of the belt, the belt will release the -a: from the JIL. As a result, the belt is torn by Kaede.Therefore, there is a gold X+ inside.
Rubber belts with embedded R-coats, etc. are also used in some cases, but as mentioned earlier, these special belts are extremely convex and curved, so they are replaced with existing belt conveyor belts. Alternatively, there is a drawback that replacing the entire belt comparator Y will result in a significant increase in equipment costs.

。On the back side of the rubber bell (14) located directly below the hopper 12, there are a plurality of foreign object detection members 15 (to be described later) (bell) 14t-
They are arranged to cross at right angles, and the supply 1Qi16 connects them in series.
As shown in FIG. 2(a), FIG. 2(b) showing its planar shape, and FIG. 3 showing its side profile, the foreign object detection member 15 is made of glass, ceramics, asbestos, hard plastics, etc., which are brittle and easily damaged. It is formed of a thin plate of material, and a conductive portion 17 is provided on its surface by forming a conductive metal film, pasting a metal foil, or applying a conductive paint. Further, the front side of the carrier roller 18 (w
Each foreign matter detection member 15 is supported by a pair of support columns 19 (in this embodiment, a bell) 14 so that the foreign matter detection member 15 is located close to the upstream side with respect to the feeding direction. The foreign object detecting member 15 is connected to the support column via a regular spring 21 so that even if the bell) 14 is bent by the weight of the conveyed object 20 above, the foreign object detecting member 15 can follow this and displace downward. Teru. A control device 22 having a built-in power source (not shown) is connected to the power supply IVJ16 via a sensor 23, and the power source for the front 1d drive motor 13 is also taken out from this control device [22]. The sensor 23 detects a change in resistance of < jjV, 9 based on damage to the foreign object detection member 15 as a change in current in this embodiment.
This detection signal is transmitted to the control device 23.The sensor 23 may be one that directly detects the change in resistance, or it may be interpreted as a change in the applied voltage. The control device 22 may be
It controls the operation of the υ motor 23, and the sensor 23

In order to break the current p1c during JIP, the electric power 11+Ij is cut off and the sensor 23 detects it (Li is connected to the control device 2).
2, the operation of the drive motor 13 is immediately transmitted to the control device 2.
Stop by 2. Therefore, the belt 14 does not continue to move until the conveyed object 20 is caught on the carrier roller 18 or the like, and tearing of the belt 14 is therefore completely prevented. In addition, since the foreign object detection member 15 can be displaced in the vertical direction, the shoe) x2. There is no risk of damage due to the impact of the conveyed object 20 falling from $, and malfunctions can be prevented.
