Conveyor system having an alerting means}

According to the present invention, visual means such as lamps or auditory notification means such as sound are provided outside the conveyor system to indicate whether the conveyor belt is operating or not, and provide a switch operator located far away from the conveyor line as well as a worker located near the conveyor line. It is an invention related to a conveyor system that can

And, without interference with the side cover, the invention relates to a conveyor system having a side cover installation structure capable of electrically connecting the generator provided inside the return conveyor line and the notification means installed outside the conveyor system. .

A conveyor system is a device for continuously transporting various objects, raw materials, and the like, and FIG. 1 schematically shows the configuration of a general conveyor system.

Referring to FIG. 1, the conveyor system includes a carrier roll 11a for driving a belt loaded with transported goods 1 and a return roll 11b for conveying (returning) the belt B. (10) is provided. This belt conveyor 10 has a configuration supported by a frame 20 .

According to the conveyor system of this configuration, cover devices such as an upper cover and a side cover are provided to prevent transported goods transported through the belt conveyor 10 from being blown away or exposed to the external environment.

As shown in FIG. 2 , the upper cover 14 refers to a cover installed on the frames 11 and 20 to shield the upper region of the belt conveyor 10 . The upper cover 14 serves to prevent transport transported on the belt conveyor 10 from scattering or from getting wet due to snow, rain, or the like. The upper cover 14 may have a shape having a semicircular cross section, as shown in the example shown in FIG. 2, and in this case, both ends may have a configuration coupled to left and right side frames, respectively.

And, as shown in the example shown in FIG. 2, the side cover 12 shields both side portions of the return roll 11b to prevent falling coals, fallen powder, or transported goods piled up in the return unit from scattering. These side covers are usually installed detachably to the frame 20 in the form of a steel plate or rubber plate. When servicing the belt conveyor 10 or replacing rolls, the side cover 12 is separated from the frame 20 and the side of the return conveyor line is opened to perform maintenance or replacement work. By attaching the side cover again, the side of the return conveyor line is shielded again.

By the way, the conveyor system is an industrial machine with a very high risk of safety accidents, and industrial accidents such as being caught, trapped, and falling frequently occur until recently. As a safety device to reduce the risk of such a conveyor safety accident, there is a full code switch to stop the operation of the conveyor system in case of an emergency, but a clear signal is transmitted between the 'switch operator' and the operator before operating the operation switch. this is absolutely required

Analyzing the types of recent industrial accidents, accidents that occur due to the lack of clear signal transmission between switch operators and workers account for a large proportion.

In particular, in the case of a conveyor system having cover devices such as an upper cover 14 and a side cover 12 as shown in FIG. 2, it is not easy to visually check the operating state of the conveyor system, especially the conveyor system. In many cases, it is not possible to accurately check the operating state of the conveyor system at the location of the switch operator far away from the switch operator, and inaccurate signal transmission between the switch operator and the worker is highly likely to cause fatal industrial accidents.

Therefore, there is a need for a safety device that can provide a switch operator located far away from the conveyor system as well as a worker located near the conveyor system by using a visual notification such as a lamp or an auditory notification means such as sound to determine whether the conveyor system is operating or not. It is becoming.

Furthermore, the conventionally known side cover made of a steel plate is very heavy, so it is difficult to attach and detach, and this causes an increase in maintenance time and risk factors.

Korean Patent Registration No. 10-2210540 (registered on January 26, 2021) (hereinafter referred to as 'prior art 1') discloses a side cover made of an elastomer material, but the side cover has wind pressure resistance (ie, no deformation even in drafts). , the ability to firmly shield the side of the return conveyor line), one or more weights are provided inside the side cover. For this reason, since the weight of one side cover made of rubber plate material disclosed in Prior Art 1 exceeds almost kg, the possibility of industrial accidents in the musculoskeletal system of workers during the attaching and detaching operation of the side cover is very high.

In addition, in the case of visually checking the return conveyor line, it is preferable to perform inspection work in a state in which the side cover 12 is only half-opened without completely flipping it open. ) is a structure in which it is impossible to open only half.
