DETAILED DESCRIPTION OF THE INVENTION

[0001]

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 which takes out finished beads which are sequentially conveyed, and automatically aligns and stores them with a separator interposed therebetween. It is about.

[0002]

2. Description of the Related Art Conventionally, when a completed bead is to be taken out and stored, a method of removing the bead by an operator and stacking it or suspending it by hanging it on a rack or the like has been used. Because it is in an unvulcanized state, if the beads are stacked or hung closely, it is necessary to work to separate the beads in a later work because the beads are in close contact with each other,
Conventionally, the work is generally performed while interposing an adhesion preventing member called a resin separator.

[0003]

However, performing the above-mentioned work manually requires a lot of labor and time, the work efficiency is extremely poor, and it is necessary to improve workability and productivity. There was a problem that I could not do it. The present invention has been devised in view of such a conventional problem, and by taking out completed beads that are sequentially conveyed and automatically aligning and storing them while interposing a separator,
It is an object of the present invention to provide a bead take-out / alignment / storage device which can be automatically performed without manual operation and significantly improves workability and productivity.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a completed product swivel shaft which can be swiveled and indexed, and a separator swivel shaft which are vertically erected at a predetermined interval. A plurality of finished product storage arms are horizontally stretched on the finished product turning shaft, and a separator storage arm is horizontally stretched on the separator turning shaft. At the top, a separator transfer means for transferring the separator hung on the separator storage arm to the finished product storage arm and a bead transfer means for transferring the completed bead to the completed product storage arm are installed and completed. The gist is that the finished beads are arranged and stored by alternately interposing separators in the article storage arm.

[0005]

According to the present invention, a completed bead formed as described above and continuously and automatically formed is taken out by a bead transfer means and automatically transferred to a finished product storage arm. Between each finished bead, separators are alternately interposed by the separator transfer means and aligned and stored, so that the operation can be performed automatically without manual operation, and workability and productivity can be significantly improved. Things.
