【発明の詳細な説明】
（産業上の利用分野）
化学、薬品、醸造などの業界において、材料を攪拌する
場合とか、家庭用や職業用の洗濯機で洗濯物を攪拌する
場合には、攪拌機の翼を自動的に短時間の正転と短時間
の逆転をくシかえず攪拌機が使用される。本発明は、こ
の撹拌機用自動逆転装置に関するものである。[Detailed Description of the Invention] (Industrial Application Fields) In the chemical, pharmaceutical, and brewing industries, agitators are used to agitate materials, or to agitate laundry in household or professional washing machines. The stirrer is used without changing its blades automatically for short periods of time in forward rotation and short periods of reverse rotation. The present invention relates to this automatic reversing device for a stirrer.
（従来例の構成と問題点）
自動逆転装置には、その方法として原動機、例えば電動
機を正逆転する方法と、機械装置で行う方法とがある。(Structure and Problems of Conventional Example) There are two methods for automatic reversing devices: a method in which a prime mover, for example, an electric motor, is reversely reversed, and a method in which a mechanical device is used.
前者の方法は、正転、又は逆転運動の時間をかなシ長く
とらないと、通常の電動機では焼損又は寿命の低下を惹
起することが多い。The former method often causes burnout or shortened lifespan of ordinary electric motors unless the time for forward or reverse rotation is long enough.
回転子の慣性を小にしたいわゆるサーボモータなどを採
用すれば可能であるが、高価である。又電動機の制御に
も工夫を必要とする。後者の機械的に行う方法では電動
機は常時一方向のみに回転させ、機械的な工夫で正転と
逆転を行わせる方法であり、一般的であるが、例えば、
機構が複雑であったシ、入力軸と出力軸とが同−中上・
線になく、いわゆるオフセットがあるため、機械全体の
バランスが悪くなって振動が多いという問題がある。It is possible to use a so-called servo motor with a small rotor inertia, but it is expensive. Also, the control of the electric motor requires some ingenuity. In the latter mechanical method, the electric motor is always rotated in one direction, and the motor is mechanically devised to perform forward and reverse rotation, and is common.
The mechanism was complicated, and the input shaft and output shaft were the same.
Since the machine is not aligned with the line and has a so-called offset, there is a problem that the balance of the entire machine becomes poor and there is a lot of vibration.
又正転と逆転と回転数が変ったシ、正転から逆転に移る
際、慣性力によって、切替が阻害され、機構に無理がか
かり、破損し易いという欠点等がある。Moreover, when the rotational speed changes between normal rotation and reverse rotation, switching from normal rotation to reverse rotation is inhibited by inertia force, which puts stress on the mechanism and causes it to be easily damaged.
第１図は従来の自動逆転機構の構造を示すもので、扇形
歯車０１の溝０２にクランク円盤０３のピン０４を係合
させた構造で、クランク円盤ｏ３の回転によって扇形歯
車は早戻りの運動をする。Figure 1 shows the structure of a conventional automatic reversing mechanism, in which a pin 04 of a crank disk 03 is engaged with a groove 02 of a sector gear 01, and the sector gear moves in a quick return motion by the rotation of the crank disk o3. do.
従って歯車部０５と出力歯車０６を噛合せれば、出力軸
０７は、原動機につながるクランク円盤０３の一定速度
の回転に対し、扇形歯車０１を介して早戻りの正逆回転
をする。Therefore, when the gear portion 05 and the output gear 06 are meshed, the output shaft 07 rotates quickly in forward and reverse directions via the sector gear 01 in response to the constant speed rotation of the crank disk 03 connected to the prime mover.
この装置にあっては、（１）入力側の軸、すなわちクラ
ンク円盤の駆動軸は、出力軸０７と同一中心軸線中にな
いので、全体の構造バランスがとれていない。従って他
の装置例えば入力側につなぐ減速機等と連結するときと
か、この逆転機構を入力軸を中心にして全体を回転させ
たいときなど、取付けが複雑になったシ、振動上のアン
バランスが生ずる。（２）、次に、構造上、ピン０４が
ａ −ｍ〜ｂ間を移動する時間とｂ −ｎ −ａ間を移
動する時間が異なるので出力軸の正逆回転は速度が異な
り、回転角と時間との関係は、第３図のへ曲線が示すご
とくなり、８曲線のような正り玄曲線にならない。In this device, (1) the shaft on the input side, that is, the drive shaft of the crank disk is not on the same central axis as the output shaft 07, so the overall structure is not balanced. Therefore, when connecting to other devices such as a reducer connected to the input side, or when you want to rotate this reversing mechanism as a whole around the input shaft, installation becomes complicated and vibration imbalance occurs. arise. (2) Next, due to the structure, the time for the pin 04 to move between a - m and b and the time for it to move between b - n - a are different, so the forward and reverse rotations of the output shaft have different speeds, and the rotation angle The relationship between and time is as shown by the curve shown in Figure 3, and it is not a straight curve like the 8 curve.
従って、出力軸０７につながる負荷の影響で、歯車部及
びピンに早戻υ時（ピン０４がａ −ｍ −ｂの間）に
無理がかかシ易いという問題がある。Therefore, due to the influence of the load connected to the output shaft 07, there is a problem in that strain is easily applied to the gear portion and the pin during early return υ (when the pin 04 is between a-m-b).
このように、従来の方式による自動逆転機構は、入力軸
と出力軸とが同一中心線上に並ばないものや、入力軸を
中心とする装置全体の・ぐランスがとれていないものが
あシ、正転と逆転との回転速度が異なシ、正転から逆転
に移るときとか、どちらか一方の回転のときに歯車等に
無理がかかり易い等の欠点がある。As described above, in conventional automatic reversing mechanisms, the input shaft and output shaft are not aligned on the same center line, or the entire device is not balanced around the input shaft. There are disadvantages such as the rotation speeds are different between normal rotation and reverse rotation, and gears are likely to be strained when changing from normal rotation to reverse rotation or when rotating in either direction.

The tooth portion of the sector gear is configured to be loosely engaged with a groove provided in a central radial direction portion of the sector gear and mesh with an output gear having an output shaft on the same center line as the input shaft,
The electric motor rotates in a fixed direction, but the output shaft provides forward and reverse rotation output.

ている出力歯車５は、当初右回転であったものが、途中
から左回転に変る０つ′ｉ′シ、遊星歯車２，２′の１
回転で出力歯車５は右回転と左回転とを各１回行なう。Assuming that a clockwise rotational force at a constant speed is applied from the input shaft, the sun gear 1 directly connected to the input shaft applies a counterclockwise rotational force to both the planetary gears 2 and 2' that mesh with the sun gear 1. Since the pins 3 and 3' are attached to the planetary gears 2 and 2' near their tooth roots in a symmetrical position with respect to the center of the sun gear l, the planet gears 2 and 2' and pins 3 and 3' are attached to the crankshaft. Acting as a disk, the sector gears 4, 4' are swung in alternating directions left and right about the fulcrum shafts 6, 6' via the grooves 41, 41' of the sector gear 44'. Of course, these fulcrum shafts 6, 6' have planetary gears 2, 2' located symmetrically with respect to the input and output axes.
It is installed in such a way that it does not interfere with the movement of the person. Sector gear 4, 4
The motions of ′ appear to be in opposite directions. That is, initially, both claw gears 4 and 4' rotate to the left, apparently swinging in opposite directions, and after passing the maximum amplitude (Fig. 2 shows this moment), they now turn to the left. Changes to rotation. Therefore, the output gear 5, which meshes with the sector gears 4 and 4' and is arranged on the same line as the input axis, rotates clockwise at first, but then rotates counterclockwise midway through the 0'i' series. , 1 of planetary gear 2, 2'
During the rotation, the output gear 5 performs one clockwise rotation and one counterclockwise rotation.
しかし、右回転と左回転とは回転速度が異り、ビン３，
３′が支点軸６，６′側に来た場合の方が、出力側に来
た場合に比べて速度が早い。However, the rotation speeds are different between right rotation and left rotation, and bin 3,
When 3' comes to the fulcrum shaft 6, 6' side, the speed is faster than when it comes to the output side.

In the case shown in the figure, 1l-1:Tx>Tz, and the result looks like curve A.

れば差はゼロとなり、右回転と左回転の速度は同一とな
って８曲線のような正弦曲線となる。なお、Ｃ曲線につ
いては後述する。This difference between the left and right rotational speeds decreases as the pinch circle (R) of the sector gears 4, 4' becomes larger. Therefore, if R-ω, the difference becomes zero, and the speeds of clockwise and counterclockwise rotations are the same, forming a sinusoidal curve like the 8-curve. Note that the C curve will be described later.

形となる。As in the case of FIG. 2, the power is transmitted to the input sun gear 11.
The pins 13 and 13' of the planetary gears 12 and 12' alternately give reciprocating motion to the racks 14 and 14', and the output gear (binion) 15 is
Repeat rotation and counterclockwise rotation. Ranks 14, 14' are supported by sliders 16-1, 16-2, 16-1', 1
6-2'. Now, when a rotational force at a constant speed is applied to the input sun gear 11, the relationship between the rotation angle of the output gear 15 and time takes the form of a sine function, as shown by the 8 curve in FIG.
すなわち、右回転と左回転の時間は同一である。That is, the time for right rotation and left rotation is the same.
この点が第２図の方式と異なシ、機構的にはスライダー
の部分が必要となる。This point is different from the method shown in FIG. 2, and mechanically a slider part is required.

車２，２′と扇形歯車４，４′とを連結すればよい。As mentioned above, in both the systems shown in Fig. 2 and Fig. 4, the sector gear 4
Although the bins 3 and 13 mounted on the planetary gears 2 and 12 are used to drive the racks 14, they can also be driven by connecting rods. Especially in the case of sector gear system,
When the load on 3 approaches the fulcrum axis, it increases considerably compared to when it moves away from it, but this phenomenon does not occur when connecting with a connecting rod. That is, as shown in FIG. 5, the planetary gears 2, 2' and the sector gears 4, 4' may be connected by connecting rods 42, 42'.

, 42' are farther away from the center of the planetary gears 2, 2', and the required time is different for the half cycle of α shown in the figure and the next half cycle of β, which is in the relationship shown by curve C in FIG. 3.

動機にかかる負荷が軽減される。As mentioned above, the automatic reversing function can be fully demonstrated with the methods shown in Figures 2, 4, and 5, but there are some problems when actually applying it, and the important one is that the gears, etc. Loss 1
The problem is how to reduce the risk. Now, when the stirring blades are about to shift from normal rotation to reverse rotation, the kinetic energy of the water flow and laundry is transferred to the automatic reversing device via the stirring blades, and the rotational energy of the stirring blades themselves is also added, causing normal rotation. Try to continue. If a spring 21 is provided to absorb this inertial energy and facilitate reverse rotation, the energy absorbed by the spring will be released during reverse rotation, thereby reducing the load on gears and the electric motor.

As described above, since the automatic reversing device 37 alternately rotates clockwise and counterclockwise, the stirring blade 32 connected to its output shaft 34 also periodically rotates clockwise and counterclockwise. Therefore, the laundry in the washing tub 3 is effectively washed. With an agitating washing machine like this one, there is less damage to the laundry.
A jet washing machine is unique in that it can wash a large amount of laundry.
