Reel for band plate, band plate feed device with reel, and band plate feed method

Abstract

The invention provides a reel for a band plate, a band plate feed device with a reel, and a band plate feed method which makes the winded band plate rotate as an integral body to prevent loosening or tightening, and provides a band plate in an expected length relative to the supply requirement at an expected speed. The reel for a band plate comprises core materials which are raw materials with band plates formed by winded magnetic materials, and a magnet which is disposed at any one of two sides of the raw material or at both sides of the raw material. The movement of the band plate with respect to the core materials in the winding direction is prohibited by using the magnetic force to adsorb the band plate. A pair of side plates is disposed on the core materials. The movement of the raw material in the width direction is limited due to the fact that the raw material is clamped by the side plate from two sides. A magnet is disposed at one side or both sides of the side plate. The feeddevice comprises a reel for a band plate, a conveying motor which makes the reel for a band plate to rotate and feeds the band plate which is unfastened from the periphery along a radial direction tothe outside, and a controller which controls the conveying motor based on the information related to the band plate feeding.

Description

technical field [0001] The present invention relates to improvement of a strip reel for storing a strip as a raw material supplied to a strip winding device and the like in a winding manner, and a strip supply device having the reel. Background technique [0002] For example, a toroidal coil used as an inductor such as a power line filter is composed of a toroidal core and a conductive wire wound around the toroidal core via an insulating material. Conventionally, as a toroidal core constituting such a toroidal coil, a magnetic strip is wound several tens of times around a rotating core, and the core is pulled out from the wound magnetic strip to obtain a toroidal core. Furthermore, there is provided a winding device for a wound core in which, in order to obtain the ring-shaped toroidal core, a reel in which a magnetic strip plate as a raw material is wound is prepared, and the coil is passed by using a roller. The reel is rotated to be guided by the rewound strip, and the ...

Problems solved by technology

In this way, the inertial force near the outer periphery of the raw material composed of the wound strip is further increased. Even if the rotational acceleration of the central part of the raw material can be made to match the rotational acceleration of the reel, it is difficult to make the raw material with the increased inertial force The rotational acceleration of the strip plate near the outer periphery of the

Therefore, it becomes more and more difficult to rotate the entirety of the raw material including the strip to be wound integrally with the reel
