Technical Field

The present disclosure relates to the roller mill machine used for grinding grains, which provides ease of use through several detection operations, and stops working when a dangerous situation is detected.

Prior Art

Grain (cereals) is the generic name given to products such as wheat, barley, oats, rye, corn, millet, rice, and so on, and to the seeds of these products. More than 60% of people's daily diet consists of grains and foods made from grains. The majority of these nutrients consist of bread, pasta, biscuits, and the like, which are obtained by mixing the grains made into the flour with various substances.

The process of turning grains into flour is called grinding. The grinding of grains is a method that has been used since antiquity. The first models of roller mill machines were stone mills, which are still in use today. However, grinding in stone mills requires a lot of workforce and time. For this reason, roller mill machines are used particularly in industrial production processes where grains are used as intermediate products in the form of flour.

The roller mill machines used today consist of units that provide grinding of products. Sensors such as bearing temperature sensor and piston position sensor are used in these machines, but these sensors are not able to provide sufficient data. Therefore, the roller mill machines used today require different sensor configurations used for different purposes.

In the literature, the patent application document no. TR2017/19494 describes a device and method for the production of flour and/or semolina. The device in the related document is characterized in comprising at least one grinder designed as a high-pressure roller mill. The grinder has at least one feeding orifice and at least one discharge orifice. The grinding arrangement comprises both at least one separation process for separating the milled products into the finer milled product and the coarser milled product, as well as a feedback arrangement for feeding back at least a portion of the coarser milled product to the feeding orifice of the grinder. However, the device described in this document does not contain enough sensors that offer ease of use to the user.

As a result, due to the above - mentioned drawbacks and the inadequacy of the existing solutions, an improvement in the technical field has been required.

The Purpose of Invention

The invention is inspired by the existing circumstances and aims to solve the above-mentioned drawbacks.

The main purpose of the invention is to provide ease of use through the many sensation processes it has performed.

Another purpose of the invention is to stop operation when a dangerous situation is detected.

In addition to the use of few number of data acquisition methods in the prior art, such as detection of current bearing temperature and piston position, the roller mill machine of the invention comprises sensors that measure the vibration value, pressure value, blockage of inlet bunker, power measurement of main motor, positioning of main roller, belt temperature value, main roller rotation control, feed roller rotation control and environmental factors.

The structural and characteristic features and all advantages of the invention outlined in the drawings below and in the detailed description made by referring these figures will be understood clearly, therefore the evaluation should be made by taking these figures and detailed explanation into consideration.

Detailed Description of the Invention

In this detailed description, the preferred structures of the roller mill machine (1 ) of the invention are described only for a better understanding of the subject-matter.

The present invention relates to the roller mill machine (1 ) used for grinding grains, which provides ease of use through performing several detection operations.

As shown in Figure 1 , the roller mill machine (1 ) has a body (2) which surrounds all elements. The input of ready-to-process grain into the body (2) is made from the inlet bunker (3). Whether the inlet bunker (3) is blocked or not is measured by the blockage sensor. If the blockage sensor detects that there is a blockage in the inlet bunker (3), it produces the signal to stop the roller mill machine (1 ).

The grinding group (4) performs the grinding of grain transmitted from the inlet bunker (3). Whether compressed air is sufficient to open and close the rollers in the grinding group (4) is measured by the air pressure sensor.

The operation performed in the roller mill machine (1 ) is controlled and commanded instantly by the operator through the control board (5). The automation group (6) ensures that the operations performed by the operator through the control board (5) are carried out in a certain order. Automation group (6) includes PLC, printed-circuit cards and such electronic elements.

As shown in Figure 2, the belt pulley system (A) assists in the rotation of the grinding group (4). The position of the main roller in the belt pulley system (A) is provided by the position sensor (7) shown in Figure 3 and Figure 8. The rotational operations of the grinding group (4) are also carried out with the help of the main motor. The amp ratings of the said main motor are measured through the power sensor. Abnormal conditions such as high currents or so are detected by the power sensor, and the power sensor produces a signal to stop the roller mill machine (1 ) in such circumstances.

In the roller mill machine (1 ) the operator is automatically detected. The human recognition sensor (8) shown in Figure 10 enables the control board (5) to be activated when the operator approaches the body (2).

As shown in Figure 4, the roller mill machine (1 ) comprises an environment sensor (9) that measures environmental factors such as temperature, humidity, atmospheric pressure.

The rotation of the feeding roller in the belt pulley system (A) is controlled by the primary control sensor (10) shown in Figure 5. Through this control process, any belt breakage that may occur in the belt pulley system (A) can be detected.

The rotation of the main roller in the belt pulley system (A) is controlled by the secondary control sensor (1 1 ) shown in Figure 6. Through this control process, any breakage or skidding that may occur in the timing belt of the belt pulley system (A) can be detected.

The temperature change experienced in the timing belt of the belt pulley system (A) is monitored by the temperature sensor (12) shown in Figure 7. When the related temperature value reaches the critical level, the temperature sensor (12) produces the signal to stop the roller mill machine (1 ).

The vibration sensor (13) shown in Figure 9 is used for predetermining any damage to the bearing roller assembly in the belt pulley system (A). In this way, predictive maintenance operations are provided for the said bearing roller assembly.
