DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for assembling an annular mold for a V-belt. More specifically, the present invention relates to an annular mold (ring mold) on which a V-belt is mounted, and the V-belt is taken out. The present invention also relates to an apparatus and a method for assembling an annular mold for a V-belt capable of continuously performing a process of applying a release agent to an annular mold and a series of steps of installing the annular mold on a lifter.

[0002]

2. Description of the Related Art In a step of vulcanizing a V-belt, a plurality of annular dies having an unvulcanized V-belt mounted on a lower lid are stacked by hand, and the upper lid is installed. The group was assembled and placed in a vulcanizer for vulcanization. And after vulcanization, after removing the bolts fixing the annular mold by the operator, remove the top lid with a hoist,
Thereafter, the V-belt and the annular mold were successively and alternately taken out by hand. However, since several tens of annular molds, which are heavy, are disassembled continuously, this causes low back pain to the operator, and also causes the productivity per unit time to fluctuate greatly within a day. There were problems such as becoming.

[0003] For this reason, an apparatus for automatically disassembling and assembling an annular mold has been conventionally improved. For example, Japanese Patent Publication No. 5-11010 discloses that a vulcanized V-belt located at an upper position in a plurality of annular dies is replaced with an unvulcanized V-belt, and then the vulcanized V-belt is moved toward a lower position. There has been proposed an apparatus for automatically disassembling and assembling an annular mold so that a belt is repeatedly replaced with an unvulcanized V-belt.

[0004]

By the way, in the conventional apparatus, a vertically moving mold can be automatically disassembled or assembled by an assembling claw or a separation claw. However, the V-belt is set so as to be taken out. Process,
No consideration is given to a series of steps such as a step of applying a release agent or a step of stacking dies.

The present invention has been made in order to solve such a problem. The annular mold is set so that the V-belt can be taken out, and the process is continuously shifted to the next step to automatically and sequentially form the annular mold. An object of the present invention is to provide an apparatus and a method for assembling an annular mold for a V-belt that can be stacked.

[0006]

That is, the invention according to claim 1 of the present application is directed to an apparatus for assembling an annular mold for a V-belt, which takes out a V-belt from an annular mold and sequentially stacks the annular molds. After setting the annular mold in a horizontal state and taking out the V-belt, a mold setting / conveying means for conveying the V-belt to the next step, a release agent applying device for applying the mold release agent to the annular mold, and conveying the same.

It is set on the lifter 9. At this time, the lifter 9 descends.

Subsequently, the annular mold 12 is rolled out, and the transfer section 64 of the mold setting transfer means 6 accommodates the transfer section 64 in an inclined state, and is turned around the rotary shaft 67 by the operation of the cylinder 68 to be in a horizontal state. Change your position. After clamping the annular mold 12 between the pair of mold fixing rods 65, 65, the operator removes the V-belt 11. The inclined conveying section 64 is turned around the rotating shaft 67 by the operation of the cylinder 68 to change the posture to a horizontal state, and the annular mold 12 is moved to the pair of mold fixing rods 65, 65.
After that, the operator takes out the V-belt 11.

While the annular mold 12 is moved by the driving roller 71 of the release agent applying device 7, the release agent in the tank 74 is supplied from the upper and lower spray nozzles 77 by the pump 75 to the application chamber 7.
The upper and lower surfaces of the annular mold 12 that has entered the mold 8 are simultaneously sprayed and applied.

Then, as shown in FIGS. 7 and 8, the annular mold 12 is transported by the drive roller 81 of the self-propelled transport means 8, and the transport portion 82 is completely covered by the lifter 9 and advanced to a position where it overlaps. The drive roller 81 is driven only when the annular mold 12 is conveyed and stacked, but is stopped when it overlaps the lifter 9. Thereafter, as shown in FIGS. 9, 10 and 11, the annular mold 12 is placed on the lower cover 13 while the tip of the annular mold 12 is grounded to the lower cover 13 and retreated. At this time, the fall buffer 87 alleviates the collision sound when the annular mold 12 falls. When the annular mold 12 is installed, an unvulcanized V-belt is attached.

The above operation is repeated until the last annular mold 12 is set on the lifter 9. When this is completed, FIG.
Then, the upper lid 14 is set by the hoist 97, and bolts are inserted to finish the mold assembly 10 as shown in FIG.
