  In each figure which showed the whole of the stirrer A of FIGS. 1-3, the structure of this stirrer A is comprised with the following components.

  The machine base A1 of the stirrer A includes a square base 1 and a support column 2 having a flat columnar shape standing at a substantially center 1b (center) of a rear portion 1a of the base 1, and includes equipment (stirring). It is made of an aluminum material that reduces the weight of the device (including the machine A) and reduces liquid adhesion.

  A support arm for loosely fitting a pair of holes 300 provided on the base end side 3b of the pair of lifting guides 200 provided on the support column 2 of the machine base A1 with an interval on the front side 2a of the support column 2 3 is mounted on a cantilever type (an example. The same applies to each component hereinafter). The support arm 3 is always in a horizontal state with respect to the plane of the base 1 using the hole 300 and the depth of the hole 300 and the like with respect to the support column 2 via lifting means described later. , Provided to be movable up and down. A rotating shaft 6 of the stirring blade 5 is suspended from the free end side 3 a of the support arm 3, and a base end side 6 b of the rotating shaft 6 is jointed to the output shaft 7 a of the second drive unit 7. ing. Therefore, the rotational speed of the rotary shaft 6 is freely changed by the control of the inverter motor of the second drive unit 7. As shown in FIGS. 4 to 6, a stirring body 501 provided with stirring blades 500 is mounted on the free end side 6 a of the rotating shaft 6. As a result, the free end side of the rotating shaft 6 is supported. A stirring blade 5 is mounted on 6a. The plate-like stirring blade 500 of the stirring blade 5 is intermittently bent substantially vertically at the upper and lower sides with respect to the plate-like stirring body 501 and is biased 502 in the rotational direction (clockwise). In this example, the inner side 500a in the circumferential direction is biased 502 in the inner diameter direction, and the outer side 500b is biased 502 in the outer diameter direction. Further, the stirring blade 500 has a shape in which the inner side 500a in the circumferential direction is high in the rotational direction on the upper and lower sides, and the outer side 500b is lower in the rotational direction. By rotating clockwise, the three-component liquid mixture is cut with the stirring blade 500 on the high inner side 500a, and the three-component liquid mixture is sequentially rotated to ensure rapid mixing of three components and quality stability. it can. In addition, it is thought that it is useful for the resistance reduction with respect to this stirring blade 500 by forming the space | interval X between these stirring blades 500, and making the said high inner side 500a and the low outer side 500b into an interchange type (alternate type). It is done.

Is a structure that moves up and down. The gear and the screw shaft 13 constitute the lifting / lowering means for the support arm 3, but other structures such as a hydraulic mechanism and a link mechanism are also possible. In this example, the first driving unit 10 rotates, the gear rotates, and the support arm 3 moves up and down by raising or lowering the screw shaft 13. The upper and lower limits are controlled by a button operation in the manual operation described later, or automatically by a switch mechanism such as a sensor. In the figure, 11a is the base of the support base 11, and 11b is a leg.

  In the figure, reference numeral 15 denotes an inverted L-shaped restricting plate provided at one end 1d of the front portion 1c of the base 1, and has a triangular notch 1500 in the middle of the upper side of the restricting plate 15.

The sliding plate 16 includes a sliding piece portion 1600 having a bent shape at both ends and a sliding piece portion 1600. The fixed plate 1601 that is loosely fitted and the spring 1602 that biases the sliding plate 16 are configured. Therefore, when the bucket 20 (container) is inserted into the gap between the regulating plate 15 and the sliding plate 16, the sliding plate 16 is pressed outwardly on the side surface of the bucket 20 (fixed plate). 1601 is used as a guide, and the sliding piece 1600 moves, whereby the sliding plate 16 moves). At this time, the spring 1602 is simultaneously compressed. When the bucket 20 is further inserted and reaches the notch 1500 of the regulating plate 15, the spring 1602 is repelled by releasing the pressure on the sliding plate 16 by the amount of the notch depth. Due to the repulsive force of the spring 1602, the sliding plate 16 returns to the one end 1d side by an amount corresponding to the notch depth (moves to the left in FIG. 1). With the return of the sliding plate 16 and the movement of the bucket 20 toward the one end 1d, the substantially center of the bucket 20 is set at the center 5a of the stirring blade 5, and the regulating plate 15 and the sliding plate 16 and the reaction force of the spring 1602. The restriction plate 15 has a guide cut portion 15a on the insertion side and a restriction stop portion 15b on the rear side. Further, the sliding plate 16 has a guide cut portion 16a on the insertion side.
