Description

{System for preventing scatter contamination}

The present invention relates to a device for preventing contamination by flying substances, and more specifically, to a device for preventing contamination by flying substances that can prevent the deterioration of sensing of a heat detection sensor due to the scattering of contaminants generated when forming a forged product by a forming machine.

As shown in (a) of Fig. 1, a forged product can be processed and formed using a forming machine to form it as shown in (b) of Fig. 1. The forming machine forms the product by processing one side after fixing the forged product so that it can rotate. However, many contaminants are generated during the forming process of the product. In addition, the temperature of the forged product increases during the forming process, which may cause a problem of deteriorating the material properties of the forged product.

Meanwhile, there is a thermal imaging camera that can measure temperature changes, etc. more precisely. It is expected that a thermal imaging camera can measure the temperature of a forged product that changes when forming a forged product, but since it cannot simply measure the temperature change of a forged product, a system that senses the temperature change of a forged product through a thermal imaging camera and operates the forming machine more efficiently based on this is required.

Meanwhile, when operating a workpiece such as a forging using a forming machine, the generation of flying objects is unavoidable. Since there is a concern that these flying objects may cause a problem of lowering the sensing function of a thermal imaging camera when detecting temperature changes in the forming machine using the thermal imaging camera, there is a need for a device that can effectively handle flying objects and appropriately detect temperature changes through the forming machine.

The purpose of the present invention is to provide a system for preventing contamination by flying contaminants that can prevent the deterioration of sensing of a heat detection sensor due to flying contaminants generated when forming a forged product by a forming machine.

The purpose of the present invention is not limited to the purposes mentioned above, and other purposes not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above purpose, a device for preventing contamination by flying contaminants, which prevents a decrease in sensing due to scattering of contaminants when forming a forged product with a forming machine according to an embodiment of the present invention, includes: a sensing unit for sensing a temperature generated in a forged product during processing; and an air injection unit for injecting air to the sensing unit so that flying contaminants generated when forming a forged product by introducing outside air into the room do not interfere with the sensing of the sensing unit.

Here, the sensing unit may include a receiving body forming an receiving space inside; a thermal imaging camera, a laser pointer, and an infrared thermometer provided in the receiving body, the thermal detection sensor sensing or photographing a thermal image; and a support unit rotatably coupled to the receiving body and supporting the receiving body.

Here, the air injection unit comprises an air compression unit that forcibly sucks in outside air and compresses it; a filter that is arranged on the discharge side of the air compression unit and removes foreign substances contained in the compressed air; a flow pipe that connects the air compression unit and the receiving body and guides the movement of the compressed air; and an injection nozzle that is connected to the end of the flow pipe and is arranged inside the receiving body and injects compressed air to the heat detection sensor.

The device for preventing contamination by non-materials according to the present invention can effectively remove contaminants through compressed air when sensing a forged product through a heat detection sensor, even if contaminants flow into the interior of a receiving body accommodating the heat detection sensor, thereby preventing a decrease in the sensitivity of the heat detection sensor and increasing the reliability of the sensing results.

The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description below.

Figures 3 and 4 are conceptual diagrams of a non-product contamination prevention system according to an embodiment of the present invention.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. At this time, it should be noted that the same components in the attached drawings are indicated by the same symbols as much as possible. In addition, detailed descriptions of well-known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically illustrated.

Also, throughout the specification, when a part is said to “include” a component, this does not mean that other components are excluded, unless otherwise specifically stated, but rather that other components may be included. Also, throughout the specification, “on” means located above or below the target part, and does not necessarily mean located above in the direction of gravity.

FIG. 2 is a block diagram of a non-product contamination prevention device according to an embodiment of the present invention, and FIGS. 3 and 4 are conceptual diagrams of a non-product contamination prevention device according to an embodiment of the present invention.

Referring to FIGS. 2 to 4, a device for preventing contamination by flying pollutants according to an embodiment of the present invention is configured to remove a sensing unit using compressed air or the like in order to prevent a decrease in sensing caused by scattering of pollutants generated when forming a forged product using a forming machine (1), and includes a sensing unit (110), a control unit (120), and an air injection unit (130). Hereinafter, since the forming machine (1) can use a conventional technology, a detailed description of the water injection unit (11) and the drive motor (12) will be omitted. However, the drive motor (12) applied to the present invention may be formed as a servo motor in order to control the processing speed.

When forming a forging (P) using a forming machine (1), heat is generated while the forming machine (1) processes the forging (P), and various non-products from the forging (P) diffuse into the interior. In addition, since the forming machine (1) can rise to a high temperature, appropriate operation control for the mechanical operation of the forming machine (1) is required.

To this end, the sensing unit (110) is installed in a room where the forming machine (1) is installed to check in real time whether the temperature of the forming machine (1) is appropriate, and may be equipped with a receiving body (111), a heat detection sensor (112), a support unit (113), and a wireless communication module (114). In the present invention, the sensing unit (110) is described as being installed on the upper side of the forming machine (1), but the sensing unit (110) may be equipped in multiple numbers and installed in various locations in consideration of the shape of the forming machine (1) and indoor conditions, and the location and number thereof are not limited thereto.

The receiving body (111) is formed with a receiving space to accommodate a heat detection sensor (112). The receiving body (111) can be formed roughly in a box shape. As an example of a case in which it is formed in a box shape, an inlet hole connected to a flow path (133) of an air injection unit (130) described later is formed on the upper side, and a plurality of discharge holes capable of discharging contaminants are formed on the bottom surface. In this way, since the inlet holes and discharge holes are formed symmetrically to face each other, contaminants flowing into the interior can be effectively removed. In addition, an imaging hole is formed on the surface facing the forming machine (1) to correspond to the size of the heat detection sensor (112) so as to prevent the inflow of contaminants generated during processing as much as possible.

The thermal detection sensor (112) is capable of detecting the heat of a target object, such as a thermal imaging camera, a laser pointer, and an infrared thermometer, and senses or captures a thermal image. The thermal detection sensor (112) is fixed to the floor of the receiving space of the receiving body (111).

In addition, a general video camera can be additionally provided. When an abnormality in temperature change is detected in the forged product (P) through the thermal detection sensor (112), the general video camera captures the forming machine (1) as a general video. Then, the two images are mapped through the control unit (130) described below, so that it is possible to more accurately confirm at which location in the forming machine (1) the abnormality in temperature change occurred. In other words, since the location cannot be accurately confirmed with the naked eye, the location where the problem is located can be confirmed more precisely by mapping the thermal image on the general video, thereby making product management safer.

The support member (113) is rotatably connected to the receiving body (111), and can be connected in various ways, such as at a position adjacent to the forming machine (1), while supporting the receiving body (111). At this time, since the support member (113) forms a rotatably structure, its position toward the forming machine (1) can be easily adjusted.

The wireless communication module (114) is connected to the control unit (120) via wireless communication to transmit values sensed by the thermal detection sensor (112) and various data captured by a general video camera. Accordingly, a more effective operating system can be built by connecting without wiring in a complex indoor work environment.

The air injection unit (130) is configured to inject air so that flying materials generated when forming a forged product by introducing outside air into the room do not interfere with the sensing of the sensing unit (110), and includes an air compression unit (131), a filter (132), a flow pipe (133), and an injection nozzle (134).

The air compression unit (131) forcibly sucks in outside air and compresses it. The filter (132) is arranged on the discharge side of the air compression unit (131) to remove foreign substances contained in the compressed air. The filter (132) is composed of a plurality of filter layers, and initially filters large dust, etc., and then filters fine dust in stages, thereby preventing physical damage to workers inside due to the inflowing air. The flow pipe (133) connects the air compression unit (131) and the receiving body (111) to guide the movement of the compressed air. The injection nozzle (134) is connected to the end of the flow pipe (133) and arranged on the inside of the receiving body (111) to spray compressed air onto the heat detection sensor (112) to remove foreign substances, etc. attached to the heat detection sensor (112).

In addition, when compressed air moves along the duct (133), condensation may occur on the surface of the inlet pipe due to a temperature difference. At this time, a water droplet removal valve may be additionally provided to collect and remove the condensed water droplets, and the water droplet removal valve may be automatically turned on/off through the control unit (120).

Accordingly, when sensing a forged product using a thermal sensor, even if contaminants flow into the housing body housing the thermal sensor, the contaminants can be effectively removed using compressed air, thereby preventing a decrease in the sensitivity of the thermal sensor and increasing the reliability of the sensing results.

In addition, if the control unit (120) described above detects an abnormality in the temperature of the forged product (P) through the thermal detection sensor (112), it additionally captures an image of the forming machine (1) using a general video camera, maps the thermal image through the thermal detection sensor and the general image, and stores the history of the location where the temperature abnormality occurred. In addition, by requesting an additional precision inspection of the forming machine (1) for this part from the manager, the quality control of the forming machine (1) can be performed more effectively.

Meanwhile, the embodiments of the present invention disclosed in this specification and drawings are only specific examples presented to easily explain the technical contents of the present invention and to help understand the present invention, and are not intended to limit the scope of the present invention. It is obvious to those skilled in the art that other modified examples based on the technical idea of the present invention can be implemented in addition to the embodiments disclosed herein.
