Cam mechanism, long strip conveying method, coil winding method and device

Abstract

The invention provides a cam mechanism, a long strip conveying method, a coil winding method and a device, allowing a press part to move at a high speed and enabling conveying of a long strip or winding of a coil at a high speed without the need of enlarging a cam part or a motor which enables the cam part to rotate. A first speed-increasing / reducing range with a constant radius from a rotating center, a second speed-increasing / reducing range with different radiuses and a movement range which is located between the above two ranges and has a radius that is changed smoothly are formed at the outer periphery of a cam part, so that the cam part speeds up and then starts forward rotation. When or after the rotating speed of the cam part reaches a predetermined rotating speed, a press part is moved to the movement range to make reciprocating movement, and then the rotating speed is reduced so as to stop the cam part. When there are multiple cam mechanisms which are acting successively, before the cam part of one cam mechanism completely stops rotating, the cam parts of the other cam mechanisms start rotating, so as to convey a long strip or wind a coil at a high speed.

Description

technical field [0001] The present invention relates to a cam mechanism and its operating method, a long object conveying method and device using the cam mechanism, and a coil winding method and device, wherein the cam mechanism can freely set the operating timing and can miniaturize the cam member , and the pressing member that moves due to contact with the outer periphery of the cam member can be moved at high speed. Background technique [0002] Conventionally, the following cam mechanism is known, and the cam mechanism is provided with: a rotatable cam member; a pressing member, the pressing member is in contact with the outer periphery of the above-mentioned cam member; The pressing member with which the outer periphery of the member contacts moves back and forth. For the cam member of the cam mechanism, the shape of the cam is determined in such a way that its moving locus is formed into an expected moving locus, and the cam member is continuously rotated at a constan...

AI Technical Summary

Problems solved by technology

Therefore, there is a disadvantage that if it becomes difficult to perform forward rotation and reverse rotation of the cam member in a relatively short period of time, it becomes significantly difficult to carry out the conveyance of a long object or the winding of a coil at a relatively high speed.
