Description

Residual image inspection apparatus and the image inspection system using the same in ready-mixed mixer truck edge data drums {IMAGING DEVICES AND INSPECTION SYSTEM FOR REMAINDER INSIDE A DRUM MIXER OR REMICON AGITATOR TRUCK}

The present invention relates to a residual image inspection apparatus and an image inspection system using the same in the ready-mixed mixer truck edge data drum, and more specifically, to the presence of the residue (residual water) in the ready-mixed mixer truck edge data drum using an optical camera The present invention relates to a residual image inspection system in a ready-mixed mixer truck edge data drum which can reduce the occurrence of ready-mixed concrete defects due to changes in the ready-mixed mixture amount.

In general, concrete used in construction is formed by loading the ready-mixed concrete prepared in the ready-mixed concrete manufacturing plant on the ready-mixed mixer truck (edge data truck) and transported to the construction site by loading and hardening it.

When the ready-mixed concrete mixer truck spills the ready-mixed concrete at the construction site, concrete residue remains inside the vehicle's hopper or edge-tatter drum, so it is sprayed with water to remove it, and the counter-tatter drum is reversed to drain the washing water. When the residues such as concrete residues or washing residues remain in the mixer, the mixing amount of the ready-mixed concrete is changed to cause the quality problems of the ready-mixed concrete. If it is, the physical properties such as slump, air volume, compressive strength, and durability change due to the variation of the unit quantity planned in the concrete mix design, which causes the fatal problem of deterioration of the quality of the constructed concrete structure.

Therefore, it is necessary to check whether there is any residue in the ready-mixed concrete mixer at the time of shipment of ready-mixed concrete. For this purpose, it was generally determined by visual identification through a hopper installed on the top of the mixer truck edge data drum.

However, the method of visually identifying residues is not only difficult to identify the presence of residues due to the small hole in the hopper and the dark inside of the mixer. Although it needs to be examined quickly, the identification method using the naked eye requires a lot of manpower and time during the inspection, which causes problems such as delay in dispatching or inadequate inspection.

The present invention is to solve the problem of the residue inspection method in the conventional mixer truck edge data drum, while observing the interior of the mixer truck of a ready-mixed concrete truck using a low-quality high-definition camera, the interior of the mixer with a high brightness light source In addition to being brightly lit, the residuals of ready-mixed mixer truck edge data drums allow the camera and light source to be inserted into the housing at all times (without observation), protected and released only during inspection to observe the inside of the mixer. An object of the present invention is to provide a water image inspection device and an image inspection system using the same.

In order to achieve the above object, the present invention has an image acquisition device for inspection, which can generally be applied to a camera, thereby obtaining a moving image and a still image.

The present invention is also equipped with a light source to illuminate the interior of the dark and deep mixer.

In addition, the present invention is provided with a housing for controlling the camera by inserting the camera at all times after the emission observation by adjusting the camera in the mixer structure.

The method of adjusting the camera may include a slide or other method or a general mechanical device.

In addition, it may include any device for interlocking the plant and the management control room for the inspection of the residue, the inspection image and the camera control device of the camera can store and manage the management control room adjustment and image, for this purpose the image in the management control room Storage and monitors are installed and have a device to control the camera.

According to the present invention, since the inside of the mixer is photographed in high quality while illuminating the inside of the mixer with a high-brightness light source, not only accurate inspection is possible, but also inspection in a short time can be quickly dealt with even when there are a large number of dispatches, thereby eliminating problems such as delays. It is possible to reduce and shorten the manpower and time required for the full inspection of the vehicle.

In addition, since the camera and the light source are set in and out of the housing, they are inserted into the housing and protected at all times, so that dust and antifouling are possible, thereby improving durability of the device itself.
