Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for automatically welding a reinforcing bar made of a steel rod or wire, and automatically aligning and ordering a steel bar or a wire used as a reinforcing bar. It is an object of the present invention to provide a method and an apparatus which can supply the above-mentioned materials and can weld the reinforcing bar with high efficiency by using the material, and further can respond to the production of the multi-kind reinforcing bar immediately.

[0002]

2. Description of the Related Art Regarding various architectural or civil engineering works themselves and precast products used for them, wire rods such as steel bars are widely used for reinforcing and reinforcing concrete and the like. Other steel wire rods are supplied to each purpose of use by being made to meet the respective conditions of use for construction and cut into a predetermined length, and then joined by welding or the like at intersections of vertical and horizontal lines.

By the way, such a steel wire rod such as a steel bar has conventionally been generally supplied to a welding machine or the like by hand work. That is, the steel wire rods such as the different diameter steel bars as described above have a considerable length, and since the unevenness is formed on the peripheral surface, a large number of deposited wires bend in the length direction, and In the case of a steel bar with a different diameter, it is caught by the unevenness of the peripheral surface, so the worker pulls out each one, lifts it up, and supplies it to a welding machine, a cutting machine, or the like.

As a means for supplying such wire rods or rods, a chain having a feed claw appropriately arranged at the bottom of a stock table for stocking a large number of the materials is driven in a suspended manner to be mounted on the stock table. It is possible to sequentially pull out the charged wire rods or rods from the bottom portion, and appropriately rotate or move the material deposited on the upper portion in association with the pulling operation from the bottom portion to arrange the direction. In addition, the above-mentioned supply is performed by dropping using a slope or by using a reciprocating mechanism or a mechanism similar thereto.

In addition, the applicant of the present invention, as a device for efficiently ordering and supplying steel bars and the like to the above-mentioned prior art, in Utility Model No. 3-102515, automatically operates a large number of steel bars stored in a stock table. In such a configuration that the components are aligned and are supplied to a processing mechanism such as a welding machine through an order supply unit, a tilt table is provided in the order supply unit and a plurality of operation rods attached to the tilt table and the above Receiving members for holding steel bars descending along the tilt table are alternately arranged in the length direction of the tilt table and pivotally attached to the tilt table.
Moreover, it is proposed to provide an operating mechanism for operating each of the operating rods individually and alternately.

[0006]

With regard to the welding of the steel bars as described above, the operation of taking out and supplying the conventional general steel bars one by one must be manually performed by the operator. That is, a relatively short wire can be sequentially taken out from the stock base by a chain having a feed claw and sent out, but as a steel bar, it may have a length of 7 to 8 m or more, Moreover, in the case of steel bars that have irregularities on the peripheral surface for binding with concrete, etc., the steel bars are engaged with each other due to the irregularities even when the chain with the feed claw is driven, and the length is large and heavy. Since it bends and the order is not properly obtained, it is unavoidable to manually insert one. As for the wire rod, if the wire rod has a length of 2 to 3 m or more, it is inevitable that only one wire is loaded.

[0007] Moreover, since the charging by the operator is long and heavy as described above, it is hard work and difficult, and a long and heavy steel bar is naturally bent. Therefore, it is impossible to achieve a preferable efficiency in supplying the steel bar that bends in this way. Of course, labor costs are also high. In the case of a wire rod, even if it is light in weight, the flexibility is more remarkable, and there is a similar disadvantage.

When a slope is used for the above-mentioned supply, if the slope angle of the slope is slow, as described above, the length is large, and rolling occurs in the case of a steel bar having unevenness on the peripheral surface. It does not always slide smoothly, and when it starts to slide, a large number of slides slide at once, making it difficult to supply it accurately. On the other hand, if the slope angle becomes steeper than a certain level, the weight of the upper steel bar exerts a large overlapping effect on the lower steel bar as a pushing force. Or, it becomes easy to extrude multiple wires at the same time, and any one of them can be accurately supplied to one wire like a welding machine, and can quickly respond to processing work conditions such as pressing electricity between electrodes for processing. A stable supply cannot be achieved.

[0009] The above-mentioned actual Kaihei 3-102515 can solve the problems of the conventional ones described above to some extent and can efficiently rearrange and supply, but by a reciprocating operation which takes a considerable stroke and alternately operates. Since each bar or wire is supplied, the speed is not always sufficient, and there are disadvantages such that the equipment must have a high attitude and must be upsized.

[0010]

As described above with reference to FIG. 3, in welding the reinforcing bar, one longitudinal bar, which is a bar, is inserted and placed on the welding workbench. That is, one of the reinforcing bar members 19 as the vertical bars may be loaded by any conventionally known method, but as a preferred method, the slant supply base and the rotary transfer means are shown in detail in FIG. It is advantageous to employ and implement.

Further, according to the present invention, the welding timer is processed by the microcomputer, and the welding current, the welding time, the air pressure, etc., which are adapted to the diameter of the wire to be welded, are selected by the memorizing button operation, and all are adjusted within a short time. In fact, even when changing the set, it is possible to easily take out the residual linear material in the device and to perform the conversion operation quickly by the configuration using the inclined supply table and the rotation operation mechanism as described above. it is obvious.

FIG. 1 described above as a concrete operation example,

Supplied from and welded. The condition is that the planar distance between the charging position by the first guide 16 and the rotary transfer means 8 shown in FIG. 2 and the interelectrode charging position by the positioning means 12 is 35 mm, and the electrode distance is 15 mm. It was inserted between both electrodes 6 and 6, and the welding current was supplied, but the result of the repetition test conducted 10 times was that the tact (welding speed) was an average of 77.5 times /
min (71 to 83 times / min).

That is, the welding speed as described above is generally 35 to 40 times / min of the welding speed in the welding apparatus according to the conventional Applicant's Japanese Utility Model Laid-Open No. 105-2515 / min. It is understood that the welding speed known in the prior art is significantly improved, and that at least one equipment can achieve work efficiency equal to or higher than that of the two conventional equipment.

The inventors of the present invention have made various adjustments to the test by adjusting the distance between the charging position of the bar arrangement material by the first guide 16 and the rotary transfer means 8 and the charging position between the electrodes by the positioning means 12 as described above. However, it was possible to perform welding at a welding speed of 60 times / min or more up to an interval of about 52 mm, but if this interval is more than the above, the welding speed gradually decreases, and if it is 200 mm or more, the welding speed is generally. It was known that it was about 35 times / min.

[0049]

According to the present invention as described above, the unidirectional loading method is adopted, and the reinforcing bar material is loaded from the charging position close to the welding position. It is clear that the productivity can be significantly improved and a bar that is preferable for high efficiency can be obtained.Furthermore, it is possible to easily follow the wide variety of products that can be obtained to secure the high efficiency as described above. It is an invention that has a great effect industrially.
