BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bead take-out aligning / storing device, and more particularly to a bead take-out aligning / storing device for taking out completed beads sequentially conveyed and automatically aligning and storing them with a separator interposed. It is about.

[0002]

2. Description of the Related Art Conventionally, when a completed bead is taken out and stored, a method of taking out the bead and stacking the bead, or hanging it on a rack or the like and suspending the bead is used. Is unvulcanized, so stacking the beads or hanging them in close contact with each other will cause the beads to come into close contact with each other and to be peeled off in a later operation.
Conventionally, the work is generally performed while interposing an adhesion preventing member called a resin separator.

[0003]

However, it takes a lot of time and labor to perform the above work manually, the work efficiency is extremely poor, and the workability and the productivity are improved. There was a problem that I couldn't. The present invention was devised in view of such conventional problems, and by taking out the completed bead that is sequentially conveyed and automatically aligning and storing it while interposing a separator,
It is an object of the present invention to provide a bead take-out aligning / storing device which can be automatically carried out without human intervention and which remarkably improves workability and productivity.

[0004]
