Description

[0001] THE DEVICE FOR MEASURING THE VOLUME OF BARRELS

[0002] Technical field

[0003] The invention relates to the device for measuring the volume of barrels by non-contact method.

[0004] Background

[0005] Currently, the method used to measure the internal volume of hollow bodies was by filling the internal volume of body with liquid, which was then measured. The result was given in litres, which could be converted into other units, such as cubic metres. Another method included determining the internal volume by calculation. In this method, the exact internal dimensions of the body must be known and the internal volume is calculated from these dimensions. In this method, the volume is obtained, for example, in cubic metres, which can be converted again into litres. Both of these above mentioned examples have their shortcomings, when calculating the internal volume it is necessary to measure all the internal dimensions, which is complicated and considerably inaccurate with curved surfaces. When filling the internal space with liquid to find the volume, the shortcoming is that the internal surfaces will be contaminated with liquid or remain wet, eventually not all the liquid will flow out and the measurement will be inaccurate. For closed containers with a small outlet opening, the measurement of the internal volume is complicated or inaccurate, as existing lidar-based or other technology device has not been able to reach the inside of barrel due to its physical size.

[0006] Essence of the invention

[0007] The shortcomings described in the prior art are eliminated by the invention defined in the patent claims, the essence of which is that for measuring a volume mainly of barrels, the device is used which has frame mounted on the base equipped with arresting legs, on which the electrical cabinet with electronics and computer technology is situated. The height adjustable arm on which is installed the extendable elongated measuring probe, which is connected via movement mechanism with manually rotatable wheel for withdrawal and insertion of the probe, is mounted on the frame. The measuring probe is inserted through the hole into the barrel, where its automatic rotation is subsequently performed and the sensors record the measured distances (values) from the axis of rotation of the arm in point-by-point manner. The measured values form the point cloud, which is then used to create 3D model of the internal shape of barrel. Based on the generated 3D model, the internal volume of barrel is calculated.

[0008] The measuring probe contains at least one sensor along its length. The sensors are interconnected with the electronics and computer technology in the electrical cabinet.

Figure 3 shows the arm with the elongated measuring probe and the arresting leg with the base. Figure 4 shows the rotary wheel for withdrawal and insertion of the measuring probe. Figure 5 shows the arm with the elongated measuring probe inserted into the barrel.

[0011] Examples of embodiment

[0012] The device for measuring the volume of barrels has the frame 3 mounted on the base 1, equipped with arresting legs 2, on which the electrical cabinet 7, with electronics and computer technology, is situated. On the frame 3, there is a height-adjustable arm 4, on which is installed an extendable elongated measuring probe 5, which is connected via the movement mechanism with manually rotatable wheel 6, for withdrawal and insertion of the measuring probe 5. The measuring probe 5, along its length, comprises the sensors. The sensors are interconnected with electronics and computer technology in the electrical cabinet 7. Before measuring the volume of barrel, the barrel volume measuring device will be placed on flat and solid floor and then fixed by means of the arresting legs 2, in the equilibrium position. The correct horizontal position is checked by means of the circular levelling gauge installed on the device. The measurement of barrel is performed by the set of sensors placed in series on the extendable measuring probe 5. The measuring probe 5 comprises at least one of the sensors 8. When the main switch and the device disabling switch are switched on, several red dots appear in a line on the floor below the measuring probe 5, depending on the number of sensors. The measured barrel is placed on the wheeled base and then the barrel is moved to the extendable measuring probe 5 with the filling opening of the barrel directing parallel to the measuring probe 5. The height of the measuring probe 5 is adjusted by means of the control panel included in the electrical cabinet 7. The measuring probe 7 is inserted manually or automatically by means of the rotary wheel 6, up to the contact with the wall of the measured barrel. Subsequently, the measuring probe 5 is inserted back by 1 / 4 turn of the rotary wheel 6, so that the measuring probe 5 does not stick against the wall of barrel during the measuring process. When the measuring probe 5 is loosely inserted into the barrel to be measured, starting the measurement, the measuring probe 5 is rotated to the initial position and then its automatic rotation is performed, whereby the sensors record the measured distances (values) from the axis of rotation of the arm in point-by-point manner. The measured values form the point cloud on the basis of which 3D model of the internal shape of barrel is subsequently created. Based on the generated 3D model, the internal volume of barrel is calculated.
