It is being vulcanized. Then, the vulcanized slab sheet is punched into a dumbbell shape or the like defined by JIS with a blade die to prepare a test piece. However, the vulcanization die for this slab sheet has a heavy weight of about 30 kg on one side (4 sheets are taken) and is further heated to a vulcanization temperature of several hundreds of degrees, so the vulcanization die is pressed by a press machine. The work of the vulcanization process of putting in and out all day was extremely heavy work of handling heavy objects while being exposed to high temperatures. Therefore, automation of the slab sheet vulcanization process has been desired.

[0003]

However, the conventional vulcanization molds for slab sheet vulcanization are not considered at all for the automation of the vulcanization process. There has been a problem in that in order to peel it from the mold, it must be peeled one by one manually.

In view of the above problems, an object of the present invention is to provide a peeling device for peeling a vulcanized slab sheet from a vulcanization mold,

A rubber conveying device for supplying and discharging the vulcanized rubber, a peeling device for peeling the vulcanized rubber from the vulcanization mold, and a stocker device for supplying the unvulcanized rubber to the predetermined position and accommodating the vulcanized rubber And a process control mechanism for uniformly controlling all of the above-mentioned devices, which is a peeling device used in a fully automatic rubber vulcanizing device, in which a handle formed on the vulcanized rubber is gripped for vulcanization. The peeling device is provided with an opening / closing gripping means for peeling rubber from a vulcanization mold.

[0007]

Next, how the peeling device peels the vulcanized slab sheet from the vulcanizing mold having the above-described structure will be described.
One side of the vulcanization mold is, for example, 150 mm × 150 mm ×
In order to obtain four 2.0 mm slab sheets at the same time, the lower part of the mold has four cavities for slab vulcanization arranged in 2 × 2, and the upper part of the mold is a lid. In the lower part of the mold, for example, four substantially square bank-shaped protrusions that define each cavity are provided, and each side of each substantially square bank-shaped protrusion is respectively Shallow grooves are provided at two locations so as to cross the bank, and further, for example, four recesses are provided on one side of the lower part of the mold for connecting the shallow grooves and forming a handle on the vulcanized rubber. In the upper part of the mold, for example, a flat part facing the four cavity parts in the lower part of the mold, and an outer edge facing the mold end part of the handle facing the concave part for forming the grip in the lower part of the mold, A convex portion that forms an acute angle is provided together with the portion.

When unvulcanized rubber is carried into this vulcanization mold and heated and pressurized by an automatic press machine to be vulcanized, the rubber once increases its fluidity and fills the mold cavity portion, and then surplus. Rubber overflows from a bank-shaped convex portion that defines the cavity portion, enters the overflow region between the cavity portions, and enters the concave portion for forming the handle. When the upper part of the mold and the lower part of the mold have been separated from each other after a predetermined vulcanization time has elapsed, the inclined surface of the convex part on the upper part of the mold lifts the outer edge of the rubber grip portion and cures it from the mold. Makes rubber vulcanizate easy to peel off. Further, when the gripping means of the peeling device grips the grip portion of the vulcanized rubber and peels it from the mold, four slab sheets for one surface of the mold are formed in the groove portion that crosses the bank forming each cavity. It is connected and peeled off.
