る。 Currently, film capacitors are becoming more layered and smaller. This multilayer capacitor is manufactured by winding dielectric material and electrode foil alternately around the outer circumference of a large-diameter winding drum, then removing the ring-shaped multilayer capacitor body from the winding drum and cutting it into a predetermined size. It is something to do. However, in order to achieve the above-mentioned purpose, extremely thin films and narrow films are used in this winding process, and when winding such films, it is necessary to apply a certain tension to the film and carry out the winding process accurately. Ultra-thin films and narrow-width films have limitations in controlling the tension applied to the film and the meandering of the film as it travels, and this greatly affects the characteristics of the wound capacitor base material. Therefore, when winding the dielectric material, it is necessary to wind it accurately and with a constant tension.

下図示の実施例に基づいて説明する。 The present invention has been made in view of this, and in a method for winding film capacitors in the manufacturing process of multilayer capacitors, a roll containing materials such as dielectric material and electrode foil is directly wound onto the outer peripheral surface of the core shaft. The gist is that the film is brought into contact with a predetermined pressure and wound up while dispersing the tension applied to the film, and will be explained below based on the illustrated embodiment.

製造することができる等の利点がある。 In the figure, 1 is a winding shaft (winding shaft) that winds and forms the base material of a multilayer capacitor. It is designed to rotate. A dielectric roll 2 on which a dielectric film is wound on a part of the outer peripheral surface of the core shaft 1 and an electrode foil roll 3 on which an electrode foil is wound.
The rolls are arranged opposite each other at a constant interval, and each roll and the outer circumferential surface of the core shaft are brought into pressure contact with each other at a set pressure. Various methods can be used for this, but in the illustrated embodiment, each of the rolls is rotatably supported at the tip of a swinging frame 4, the other end of the swinging frame is engaged with a rod of a cylinder 5, By operating the cylinder, the roll is brought into contact with the outer peripheral surface of the winding core shaft under constant pressure. When the dielectric material and the electrode foil are wound around the winding core shaft and the capacitor base material 6 is formed, its thickness changes. The cylinder is oscillated according to the pressure, but the pressure contact with the winding core shaft is always kept constant. By bringing a shaft to which a roll of dielectric material or electrode foil is attached to the core shaft into contact with a predetermined pressure, the tension applied to the ultra-thin film can be dispersed, and it can be wound in this state. Therefore, it is possible to arbitrarily change the winding hardness of the capacitor base material 6. Furthermore, since the roll on which the material is wound is brought into direct contact with the outer periphery of the core shaft without using a guide roller or tension roller between the core shaft and the roll mounting shaft, there is no running resistance meandering of the film, and the characteristics are improved. It has advantages such as being able to produce a stable capacitor base material.

Furthermore, it is also possible to use a film in which the electrode foil is deposited on the dielectric material, without having to wind up the dielectric material and the electrode foil separately.
