がでるという問題点があった。The problem that Akira is trying to explain is that in the supply material LLj of the heat treatment equipment, it is possible to continuously supply the strip 1w as described above, and in particular, it is possible to weld multiple individual coils to form a large coil. Although it can be supplied in a rolled-up state, it is possible to supply steel strips W with the same width and thickness.
In order to speed up multiple coils at the same time, a fractional number of individual coils is always generated in the final stage due to the product rond. For example, as shown in Fig. 4, 18 individual coils W' are arranged in 4 rows and the uncoilers 2a, 2b are used. When spooling the coil, two fractional coils were generated at the final stage of spooling. In such a case, conventionally, a method has been adopted in which the fractional coils are stored as they are and supplied to the uncoilers 2a and 2b. However, with this feeding method, the mandrel uncoiler 12
Compared to the supply capacity from the mandrel uncoiler 12 side, which could originally supply four rows at a time from the mandrel uncoiler 12 to the spool uncoilers 2a and 2b without leaving any rows empty, the supply capacity was only 50%, and the supply capacity was only 50%. There is a problem in that the number of supplied coils varies from row to row, which causes problems in welding and other operations that are performed to start supplying the next coil.

を提供することを目的とする。Therefore, the present invention solves the problems of the conventional material feeding device, and when a single fractional coil occurs, it is divided equally among the number of rows to be wound, and the number of single fractional coils is made equal for each row. It is an object of the present invention to provide a material feeding method and a material feeding device that can draw out 100% of the feeding capacity from the mandrel uncoiler side.

As shown in the figure, when a plurality of individual coils supplied from the mandrel uncoiler 12 are simultaneously coiled in multiple rows by the coil uncoiler, if a fraction occurs in the coils to be coiled, this fraction A single coil is supplied from the mandrel uncoiler 12 to the equalizing uncoiler 17.
The feature is that the coils are equally divided into the number corresponding to the number of coiling rows of the coiling uncoiler.

When a plurality of individual coils supplied from 12 are simultaneously rolled in multiple rows by the spooling and uncoiler, if a fraction of the coils to be spooled into one turn occurs, the fractional coils are collected and the uncoiler winds the coils. It is characterized by being equipped with an equal distribution uncoiler 17 which can wind the coils so as to equally divide them into the number corresponding to the number of reservoir rows, and which has the function of supplying the coils to the former reporter reservoir uncoiler after winding. .

2b, a fraction 1, for example, the 4th
When two fractional coils are produced as shown in the figure, the fractional coils are transferred from the mandrel uncoiler 12 to an equal portion uncoiler having both winding and supply functions, as shown in FIG. In the illustrated case, the equal distribution uncoiler 17 is supplied to the uncoiler 17 via the deflation roll 19 and the tensimin wiper 20, and is equally divided into the number corresponding to the number of winding rows of the winding uncoilers 2a and 2b. When the length of the steel strip W, which is a single fractional coil, is equal to the length of the strip W4W remaining on the mandrel uncoiler 12, it is cut with a cutter 18 or the like. With this, for example, the mandrel uncoiler 12 has the 1st and 2nd rows of fractional coils W, and the equalizing uncoiler 17 has the 3rd and 4th rows of fractional coils of steel strip W wound equally, and the 1-turn sump uncoiler. -2a and 2b, following the third coil in Figure 4, weld the outer ends of the fractional coils wound around these uncoilers 12 and 17 to the inner end of the third coil. supply.

イル単体の場合も基本的には前記と同様である。In the example shown in Fig. 1, there are two fractional coils, each of which has an equal length of 1/2.
When a single fractional coil of a book occurs, two of the three fractional coils are each 1/2 the length, and the remaining one is each 1/4 the length, and these are Weld them to equal lengths, and if a single fractional coil occurs, make it 1/4 of each length to equal length, then attach the 1st and 2nd rows to mandrel anchors in the same way as above. 6-turn reservoir uncoiler 2a that winds the 3rd and 4th rows around the equal distribution uncoiler 17 on the coiler 12
, 2b, the case of a single fractional coil, which occurs when there are four or more winding rows, is basically the same as described above.

By equally dividing the coils into the number corresponding to the number of winding rows 2a and 2b, the number of coils to be supplied can be uniformly distributed for each winding row, and the coils of equal length can be supplied. According to the material feeding method according to the present invention, fractional coils are fed from the mandrel uncoiler to the equal portion uncoiler as described above, and the uncoiled coils are collected in the uncoiler. Since it is possible to divide the steel strip equally into the number of strips corresponding to the number of rows, the length of the strip steel for each fractional coil can be made equal for each number of rows, and therefore the supply capacity from the mandrel uncoiler can be increased to % can be extracted and supplied, and work such as welding when supplying the next single coil can be carried out smoothly without any problems.
