Description

A firing container transfer device for an inversion device with a cooling function and an inversion machine including the same The present invention relates to a firing vessel transfer device for a counterweight having a cooling function and a counterweight including the same. More specifically, the invention relates to a firing vessel transfer device for a counterweight having a cooling function and a counterweight including the same, which can effectively cool sensors including a rotary motor embedded in the motor roller by supplying cooling air to a motor roller that is self-rotating to transfer a firing vessel equipped in the counterweight, thereby preventing heat dissipation and preventing malfunction due to overheating. Cathode materials are a key component responsible for battery capacity and output. The manufacturing process of cathode materials consists of the following main steps. Raw materials such as lithium, nickel, cobalt, and manganese are precisely weighed and mixed (raw material mixing), the mixed raw materials are heat-treated at a high temperature to produce a positive electrode active material (calcination), and the calcined active material is ground to a uniform size. Subsequently, a coating layer is formed on the surface of the ground active material to improve performance (coating), the coated active material is dried to remove moisture (drying), and the dried active material is classified by particle size (classification). Among these, a kiln is used in the above firing step. The above-described kiln stably forms a high-temperature atmosphere inside, and raw materials can be fed in and transported by the operation of a pusher or roller. At this time, the raw materials are transported in a firing vessel referred to as saggar, refractory case, or refractory container, and are sintered through the firing process. The product contained in the firing vessel can then be discharged to the outside of the firing vessel through a process of inverting the vessel. Here, an inverter is used to invert the firing vessel containing the product by turning it 180 degrees. Here, the inverter comprises an inversion frame on which a firing vessel is placed, and a rotating device that rotates the inversion frame to invert the firing vessel. Typically, the rotating device is equipped with a rotary motor having a rotating shaft. The rotating shaft is connected to an end of the inversion frame. The rotary motor rotates the rotating shaft under the control of a controller, and the inversion frame can be inverted by the operation of the rotating shaft. In addition, a transfer device is installed on the inner lower part of the inversion frame to transfer the firing vessel to the inner side of the inversion frame. Conventionally, the above-mentioned moving device uses a power roller because it has the advantages of high power transmission efficiency, low energy loss, precise torque control, and efficient use of space as it does not require an external drive unit, as the motor is built into the roller itself. That is, the above-mentioned transfer device is composed of power molters and movable rollers installed on the outer circumference of the power molters. The power molter includes a cylindrical housing and a motor embedded inside the housing to rotate the housing. Accordingly, the power molter itself, including the housing, can rotate by the rotational force of the motor. Therefore, the movable rollers rotate in conjunction with the rotation of the power molter. Accordingly, the bottom of the firing vessel is placed on the movable rollers, and the firing vessel is moved to the inside of the inversion frame by the movable rollers that rotate simultaneously with the rotation of the power molter. Then, the moved firing vessel is fixed by fixed members formed on the inversion frame, and the rotating device rotates the inversion frame to invert it, thereby inverting the firing vessel to turn it upside down. These power rollers are used in conveying systems because they have the advantages of high power transmission efficiency, low energy loss, precise torque control, and efficient space utilization as they do not require external drive units, as the motor is built into the roller itself. Typically, a power roller is composed of a motor, a roller, a sensor, a controller, and a housing. The motor, roller, sensor, and controller are housed inside the housing. If these power rollers are exposed to high temperatures near the kiln and high temperatures from the firing vessel containing the product, the following problems may occur. In high-temperature environments, the lubricating oil inside the motor may evaporate or deteriorate, increasing friction and degrading the insulation performance of the windings, which can lead to reduced efficiency, overheating, and burnout of the motor. Sensors sensitive to temperature changes may malfunction or experience reduced measurement accuracy in high-temperature environments, which
