ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an automatic feeder for beads with bead fillers. In particular it relates to an automatic feeder for beads with bead fillers which automatically supplies stocked beads with bead fillers to a bead setter within a tire forming machine.
2. Description of the Related Art
Conventionally, in the tire forming operation, when beads with bead fillers are supplied to a bead setter within a tire forming machine, an operator manually removes beads required for one tire, i.e., two beads, from a plurality of beads with bead fillers stocked in a stock means such as a stand or the like, and thereafter supplies the beads to the bead setter within the tire forming machine directly or via an intermediate device such as a conveyor or the like.
However, this operation, i.e., where the operator manually removing the beads required for one tire from the plurality of beads stocked in the stock means and supplying the beads to the bead setter within the tire forming machine, is complicated and burdensome for an operator and is less productive.
SUMMARY OF THE INVENTION
With the aforementioned in view, an object of the present invention is to provide an automatic feeder for beads with bead fillers which enables automatic feeding of beads with bead fillers to a bead setter within a tire forming machine and which enables reduction of an operator's burden and improvement of productivity.
In accordance with the present invention, the automatic feeder for beads with bead fillers, comprises: bead stock means which has two or more stock portions, each stock portion having an automatic conveying-in function (stocking function) and an automatic conveying-out function and being able to hold a plurality of beads with bead fillers; bead removal means which removes the beads with bead fillers one by one from the stock portions of the bead stock means; a bead chuck which has a pair of bead holding portions and which receives two beads with bead fillers from the bead removal means; and bead conveyance means for conveying the bead chuck from a position at which the beads with bead fillers are received from the bead removal means to a position at which the beads with bead fillers are delivered to a bead setter within a tire forming machine.
Therefore, in the bead stock means, the plurality of beads with bead fillers are held at the stock portion due to the automatic conveying-in function, and the plurality of beads with bead fillers held at the stock portion are successively conveyed out due to the automatic conveying-out function. The bead removal means removes the beads with bead fillers one by one from the stock portion of the bead stock means due to, for example, the magnetic force of the magnets of the pair of bead holding portions. The bead conveyance means conveys the bead chuck from the position at which the beads are received from the bead removal means to the position at which the beads are delivered to the bead setter within the tire forming machine. Thus, the beads with bead fillers held at the bead stock means can be automatically supplied to the bead setter within the tire forming machine. As a result, a reduction of an operator's burden and improvement of productivity can be realized. When the beads with bead fillers are removed by the bead removal means and received by the bead chuck, a known chuck mechanism may be used.
In the automatic feeder for beads with bead fillers of the present invention, in the bead stock means, while the beads with bead fillers are conveyed out of one stock portion to the bead removal means, other beads with bead fillers may be stocked at another stock portion.
Because the bead conveying-out operation and the bead conveying-in operation (stocking operation) can be effected simultaneously by the bead stock means, operational efficiency is good and productivity further improves.
In the automatic feeder for beads with bead fillers of the present invention, the bead removal means has a slide mechanism and a reversing mechanism, and the bead removal means is slid so that a first bead with a bead filler is delivered to one bead holding portion of the bead chuck, and is slid and reversed so that a second bead with a bead filler is delivered to the other bead holding portion of the bead chuck.
Therefore, the bead removal means can efficiently deliver the two beads with bead fillers to the pair of bead holding portions of the bead chuck in a short time, and productivity further improves.
In the automatic feeder for beads with bead fil lers of the present invention, the bead conveyance means has a raising/lowering mechanism and a slide mechanism, and the bead conveyance means is raised and lowered so that interference between the bead chuck and the bead removal means is prevented, and the bead chuck is conveyed from a position at which the beads with bead fillers are received from the bead removal means to a position at which the beads with bead fillers are delivered to the bead setter within the tire forming machine by bead conveyance means raising, sliding, and lowering.
Therefore, the bead conveyance means can prevent interference between the bead chuck and the bead removal means and can deliver the bead chuck efficiently from the position at which the beads are received to the position at which the beads are delivered in a short time. Productivity further improves.
