【考案の詳細な説明】
本考案は、複数の作業者が同時に溶接作業が可
能なよう単一発電機内に複数の発電機要素を形成
した溶接機の改良に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a welding machine in which a plurality of generator elements are formed within a single generator so that a plurality of operators can perform welding operations at the same time.
従来、野外において複数の作業者が同時に溶接
作業を行なう場合は、作業者数と同数のエンジン
駆動型溶接機を用いているが、複数台の溶接機を
同時に稼働させるので、騒音、振動、排気ガスが
多く公害源となりやすい。 Conventionally, when multiple workers perform welding work outdoors at the same time, the same number of engine-driven welding machines as the number of workers are used, but since multiple welding machines are operated at the same time, noise, vibration, and exhaust emissions are reduced. It contains a lot of gas and can be a source of pollution.

つて、移動に困難を伴ない、野外作業では可搬性
に劣るばかりか、複数の発電機を同一筐体に収納
すれば複雑な構造になり、修理、維持、管理が困
難となる。 On the other hand, in recent years, models have been proposed that are coaxially coupled to an engine or drive multiple generators using a belt, but in the former case, the axial direction is longer, whereas in the latter case, the width direction is longer. , the equipment is large and difficult to move, making it less portable for outdoor work, and housing multiple generators in the same housing results in a complex structure that is difficult to repair, maintain, and manage. becomes.
このため、本出願人は先に実願昭52−179260号

した。 For this reason, in Utility Application No. 52-179260 (Utility Patent Application No. 54-101308), the present applicant previously proposed that a single yoke be divided into radial widths at equal positions so that the magnetic resistance becomes essentially infinite. narrow the field and armature windings to n
We proposed a device based on an inductor-type generator for welding, which is wound around each equally divided yoke and rotated by an engine using a rotor (inductor) with gear-shaped unevenness.
しかしながら、上記の方式では円筒状鉄心をｎ
等分位置で径方向幅を狭くする故に、機械的強度

４〜６組の界磁巻線が必要で、該界磁巻線収納溝

いばかりか、径方向幅を狭くしたため機械的強度
が小さくエンジンの振動や溶接時に発生する短絡
に伴なう電磁力によつて、継鉄部分に力が作用す
るため、変形を防ぐべく措置をとらねばならぬ等
の問題があつた。 However, in the above method, the cylindrical iron core is
Because the radial width is narrowed at equal positions, the mechanical strength decreases, and because the yoke is magnetically divided, multiple field windings are required, and two independent outputs (two people can use it at the same time). ), two sets of field windings are required, and if about 4 to 5 people are using it at the same time,
4 to 6 sets of field windings are required, and the ratio occupied by the field winding storage groove increases, and the ratio of the effective use area of the yoke drastically decreases. Due to the narrow width, the mechanical strength is small, and force is applied to the yoke due to engine vibration and electromagnetic force due to short circuits that occur during welding, so measures must be taken to prevent deformation. There was a problem.

ことになる。 Embodiments of a welding machine having multiple outputs according to the present invention will be described below with reference to the drawings. 1 and 2 show an example of a single core inductor type generator. First, the internal structure of the inductor type generator 1 according to the present invention will be explained. The stator 3 is an inductor having an appropriate number of salient poles 4 (inductor teeth).

して便利である。 The field windings 7 and 8 are connected to a DC power source 20 such as a battery or an exciter via a variable resistor 19 for adjusting the field current, as shown in FIG. in this case,
Of course, instead of using the DC power supply 20 provided separately from the inductor type generator 1, a self-excitation method using a built-in excitation winding (not shown) or the like may be used.
On the other hand, each armature winding 13, 14 is connected to a rectifier 27, 28 through a load winding 23, 24 of a saturable reactor 21, 22, respectively, as a welding current adjusting means. Welding rods 29 and 30 are connected to welding base materials 31 and 32, respectively. Each saturable reactor 21, 22
Control windings 25 and 26 are connected to both ends of the series-connected variable resistor 19 and field windings 7 and 8 via variable resistors 33 and 34 for saturation adjustment, respectively. Further, the anodes and cathodes of each rectifying device 27, 28 are connected to each other via switches 35, 36 as output number selection means, respectively. It is convenient to use the switches 35 and 36 in an interlocking manner.

3, 14 output terminals 15, 16 and 17, 18
It is now possible to take out the output from each rectifier 2.
Welding is possible through 7 and 28.

作し得ることはもとよりである。 By the way, in the case where a plurality of welding operations are performed individually and simultaneously using the outputs of the rectifying devices 27 and 28, one of the welding rods 29, for example, is used with a larger diameter than the other. When a large current is required due to welding conditions such as when welding, the variable resistor 33 is set in advance to adjust the saturation degree of the saturable reactor 21 corresponding to the welding rod 29 to the maximum value that can be adjusted. In this state, the variable resistor 19 is operated to adjust the welding current I 1 to be output from the rectifier 27 to a desired value. On the other hand, the welding current I 2 to be output from the rectifier 28
is set to a desired value by operating the variable resistor 34 and varying the control current flowing through the control winding 26 of the saturable reactor 22 to adjust the degree of saturation. Next, the welding current output from each rectifier 27, 28
A plurality of welding operations can be performed individually and simultaneously at I 1 and I 2 without causing mutual interference between the welding current circuits including each armature winding 7 and 8.
It goes without saying that the above adjustment method allows the field circuit to operate efficiently.

Of course, the degree of droop can be adjusted freely. In this case, the variable resistor 19 is adjusted to match the required maximum welding current value, and the variable resistors 33 and 34 are adjusted to obtain the respective desired welding current values. In addition,
In the embodiment, two independent armature windings 1
3 and 14, so that welding work could be performed at two locations at the same time, but this armature winding 1
3 and 14 are further divided into an appropriate number of equal parts, such as by dividing them into two at the center, and each is made electrically independent, and a saturable reactor, a variable resistor, a rectifier, and an output number selection means are interposed, respectively, and the above is achieved. The circuit is formed identically,
It is possible to simultaneously perform a number of welding operations corresponding to this equal number.

極めて有利となり実用上重要な効果を奏する。 In summary, the present invention is such that a plurality of independent armature windings are wound around the stator of a single core inductor type generator, and the output current of each armature winding can be varied by a saturable reactor. Because of this configuration, each individual output of this generator allows welding work to be performed simultaneously at a plurality of locations using not only coated welding rods of the same diameter but also different diameters.
Furthermore, the output number selection means allows the output to be used without waste. Moreover, since the current supplied to the field winding is passed through the control winding of the saturable reactor, thereby controlling the current flowing through the load winding, drooping characteristics suitable for welding can be obtained. Conventionally, separate welding machines were required for each of the above-mentioned welding operations, but the present invention is extremely advantageous in reducing the cost of welding machines and the space required for the operations, and has important practical effects. play.
