【The invention's effect】
As described above, the present invention provides a pouring mechanism including a pouring pipe, a first motor that oscillates the pipe in the X-axis direction, and a second motor that oscillates the pipe in the Y-axis direction. Since the motor and the second motor are operated by a plurality of predetermined coordinate points to perform the pouring of "no", when pouring from the pouring pipe, the position automatically determined. In order to perform the pouring of `` no '', there can be a time lag between the initial pouring part and the pouring end part. Rich coffee can be extracted.
[0026]
In particular, since the pouring pipe performs "no" pouring by a combination of swinging in the X-axis direction and the Y-axis direction, the locus of the "no" character can be easily obtained simply by changing the operation time of one motor. The size of the filter can be increased or decreased, so that the "no" pouring that matches the size of the filter can be performed.
[0027]
Further, since the second motor is fixed to the rotating shaft of the first motor and the pouring pipe is fixed to the rotating shaft of the second motor in the vertical direction, the first motor and the second motor are integrated. The pouring mechanism can be unitized, and the trajectory management of the "" can be performed before assembling to the main body. Moreover, since the pouring pipe is fixed to the rotating shaft of the second motor, the operating state of the second motor can be accurately transmitted to the pouring pipe, and the accuracy of the pouring locus can be improved.
[0028]
Furthermore, since the rotation axis of the first motor and the rotation axis of the second motor are orthogonal to each other, and the fixing position of the pouring pipe is arranged adjacent to the rotation axis of the first motor, the orthogonality of the rotation axis is When performing the pouring of "no", it is possible to select a numerical value of an accurate coordinate when setting the coordinate points of the X axis and the Y axis.
