TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic iron core supply device for automatically supplying a laminated iron core used in a medium-to-large capacity transformer to an assembly worker.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, middle- and large-capacity transformers use a stacked iron core to improve the space factor. FIG. 9 shows a state of assembling the stacked iron cores.
Lifters 4 and 5 are installed on both sides of a transformer 3 in the middle of assembling in which the coil 2 is inserted into the leg core 1. After being placed on the lifter 4 of the first worker 7, the first worker 7 peels off two to four core materials 6a at a time from the iron core 6 for the upper yoke, and then the core material group 6b is handed to the second worker 8 in a state of being aligned. The second worker 8 inserts the handed iron core material group 6b into the leg iron core 1 with a gap of about 1 mm from above the transformer 3 with more accurate alignment. By repeating this operation several hundred times, the core stacking operation is completed. All of this work is performed manually by a plurality of people, and the weight of the two to four iron core material groups 6b to be peeled off in one work is as heavy as 1 to 10 kg, and this work is repeated several hundred times. In addition, the operator requires a considerable amount of labor and is a laborious operation.
[0003]
[Problems to be solved by the invention]
In order to solve this manual work, one core material 6a is automatically peeled off from the core 6 for the upper yoke laminated in the state of FIG. 9 and is automatically transported to the hand of the second worker 8. However, it is difficult to take out the iron core material 6a one by one because the iron core 6 in which many iron core materials 6a are laminated has good adhesiveness. There is a problem that the iron core material groups 6b tend to be irregular. Further, since the number of core materials 6a to be conveyed varies depending on the width of the core material 6a, it is necessary to measure the width when the core material 6a is peeled off one by one from the core 6 for the upper yoke.
[0004]
The present invention has been made in view of the above circumstances, and reliably separates an iron core material from an iron core, takes out a different number of sheets for each width, and prepares a core sheet material group with a predetermined number of iron core members in hand. It is an object of the present invention to provide an automatic supply device for an iron core to be conveyed to a ship.
