置が変らない製品に限られていた。<Problem to be solved by the invention> In order to increase the production efficiency of mesh reinforcing bars using a wire mesh welding machine, short sub-reinforcements, which become horizontal reinforcements, are welded orthogonally to long main reinforcements, which become vertical reinforcements, at a required uneven pitch. It is clear that the sub-reinforcements on both sides of the product boundary can be welded at a particularly small pitch and then separated at the boundary. For this reason, the above-mentioned dividing technology and pitch variable technology have been developed only for products in which the arrangement of the translating main bars does not change.

する。<Means for Solving the Problems> The continuous manufacturing method of reticulated reinforcing bars of the present invention involves translating several main reinforcing bars into a wire mesh welding machine, and resistance-welding sub-reinforcing bars one by one perpendicularly thereto to form a mesh with the same shape at the front and rear ends. In the method of manufacturing reinforcing bars, the tips of the main bars pulled out from the reinforcing bar coil and placed in each of the main bar supply paths for products of various sizes of a wire mesh welding machine are cut side by side and aligned at each shearing position a certain distance before the welding position. Then, only the required main reinforcements are fed intermittently to weld the sub-reinforcements one after another, and while the main reinforcements are stopped to weld the sub-reinforcements located in front of the rear end of the product by the specified distance, Cut only the main reinforcement that has been used or will not be used in the subsequent product. 1: Cut the trailing tail at each shearing position and remove it from the rear feeding mechanism, and at the same time remove the main reinforcement that is not used in the preceding product but is waiting to be used in the subsequent product. The main reinforcement of both the front and rear products is advanced by the feeding mechanism, and after welding the sub-reinforcements on both sides sandwiching the boundary between the two products, the common main reinforcement of both the front and rear products is sheared at the boundary of the products.

ことを特徴とする。In addition, the device has the same shape at the front and rear ends, in which several main reinforcements are translated into a wire mesh welding machine, and sub-reinforcements are resistance welded one by one at right angles to the main reinforcements.
In a reticulated reinforcing bar manufacturing device, the main reinforcing bars pulled out from the reinforcing bar coils are placed on standby in the main reinforcing bars for the products of various sizes to be manufactured, and the main bars pulled out from the reinforcing bar coils are placed in each of the above supply channels, and the main reinforcing bars are placed in each piece and wire mesh welded. A main reinforcement feeding mechanism that intermittently feeds the main reinforcement to the machine, an individual shearing device installed on the supply path at a position to cut each main reinforcement at a certain distance before the welding position, and a sub-reinforcement located at the specified distance in front of the rear end of the product. During the welding stop time, if a command is received that there is a main reinforcement in the preceding product that is not in the succeeding product, the respective shearing devices and main reinforcement feeding mechanism are ordered to cut the trailing part of that main reinforcement and stop feeding. When a command is received that there is a main reinforcement that will not be used in the preceding product but will be used in the subsequent product, the control device will instruct the main reinforcement feeding mechanism to pick up the standby main reinforcement at that position, and the boundary between the preceding and subsequent products. The present invention is characterized by being equipped with a full-width shearing device for shearing the common main reinforcing bars of the previous and subsequent products between the sub-reinforcements on both sides at the place where the sandwiched sub-reinforcements come out of the welding machine.

、直ちに他のコイルに切換えて送給を続けられる。Function> Is the separate reinforcing bar that is the product of this invention mainly used for concrete plates? In that case, according to the standard, the arrangement of vertical bars should be the densest one or sparse by eliminating some. This invention takes advantage of the fact that you are only allowed to do it. In other words, by having the main reinforcing bars pulled out from the reinforcing steel coil stand by in each of the main reinforcing bars for customer-sized products of the wire mesh welding machine, the main reinforcing bars can be moved straight from each standby position without having to move laterally due to dimensional changes. I made it. Since it is pulled out from the coil, after continuously feeding several dozen vertical bars in the same arrangement, it is possible to immediately switch to another coil and continue feeding.
この発明は各主筋供給路に、主筋をくわえたり離したり
する送給機構を設けたのは当然として、さらに各個剪断
装置を加え、溶接位置より定距離手前の所で各主筋先端
を切り揃えて待機させるほか、後述の主演後尾切断用と
しても使う。In this invention, each main reinforcement supply path is naturally equipped with a feeding mechanism for gripping and releasing the main reinforcement, and a shearing device is also added to each main reinforcement, and the tips of each main reinforcement are trimmed at a certain distance before the welding position. In addition to being kept on standby, it is also used for cutting the leading man's tail, which will be described later.

、その先行製品の主筋後尾か待機中の残りの全部の主筋
先端に揃えられるのである。In other words, while welding the sub-reinforcement of the preceding product, and while the main reinforcing bar is stopped in order to weld the sub-reinforcement located the above-mentioned fixed distance ahead of the rear end of the product, the trailing cut of the main bar that is unnecessary for the succeeding product is cut on the supply path. Not only can each individual shearing device be easily operated, but it can also be aligned with the tail of the main bar of its predecessor or the tip of all the remaining main bars in standby.

たま\進む。At the same time as the above-mentioned trail cutting, a feeding mechanism is added to the waiting main reinforcement at the shearing position of each individual shearing device, which is not used in the preceding product but is necessary for the succeeding product, and by intermittent feeding thereafter, the main reinforcement is connected to the trailing reinforcement of the preceding product. The tips of the main bars of subsequent products will advance in a horizontal line. Incidentally, the common main reinforcing bars used in both the preceding product and the succeeding product are not cut by each individual shearing device and proceed as they are connected.
これにより上記先後両製品境界をはさむ両側副筋を溶接
し、それらか溶接機から出て来た所で。This welds the sub-reinforcements on both sides that sandwich the boundary between the front and rear products, where they come out of the welding machine.

切にして、先行製品と後続製品に共通な共通主筋だけを
製品境界線で全幅剪断装置で切断するだけでもよい。When each main reinforcement is sheared along the product boundary line with a full-width shearing device between the sub-reinforcements on both sides, the preceding product and the following product are separated, and the protrusion amounts from the sub-reinforcement at the ends of both the front and rear main reinforcements are all equal. In order to prevent the length from becoming longer than the standard size even if the length is equal, the excess length can be cut off using both cutting blades. Of course, it is also possible to make the relevant dimensions appropriate and to simply cut only the common main bars common to the preceding and succeeding products at the product boundary line with a full-width shearing device.

。At the same time as the above-mentioned trailing cut, as a main reinforcement in the subsequent product but not in the preceding product, the waiting main reinforcement in the corresponding arrangement is held in the feeding device, so intermittent feeding for primary sub-reinforcement welding is performed on the preceding product. The trailing cut end and the tip of the main bar of the succeeding product line up in a horizontal line. As a result, if the spacing between the sub-reinforcements on both sides sandwiching the boundary between the leading and succeeding products is appropriately selected and welded, and all the main reinforcements at the center of the boundary are cut with a shear blade of an appropriate blade width, the front and rear ends of both products can be welded. This allows the main reinforcement protrusion amount to be adjusted to the standard value.
