DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called unvulcanized V-belt having a trapezoidal cross section and covered with a cover canvas, and a plurality of such V-belts are suspended between a pair of V-pulley wheels, and the circumference thereof is increased. The present invention relates to a press vulcanizing apparatus and a press vulcanizing method, in which a part is narrow-pressure vulcanized by a mold and the position is shifted a plurality of times to repeatedly vulcanize the entire circumference, and then stretched and cooled. Specifically, in this cooling treatment process, the cooling temperature of the cooling belt, in which the residual temperature difference is distributed stepwise according to the vulcanization order immediately after full-circle vulcanization, shortens the cooling time, eliminates the scattering of cooling water droplets, and improves the working environment. It is intended to improve maintainability and the like.

2. Description of the Related Art A conventional v-belt press vulcanizing apparatus is disclosed and proposed in Japanese Patent Publication No. 45-34694. According to this, a V-belt using a polyester core wire is annealed to control elongation and shrinkage of the belt.

In this belt processing apparatus, an annealing process is performed as a dedicated process after the belt is manufactured, and the belt is processed. On the other hand, as in the present embodiment, an embodiment in which the cooling treatment step is combined with the cooling treatment step during press vulcanization to constitute an integrated step and the treatment is carried out similarly is also used. The above belt processing apparatus heats the belt, stretches the belt in the longitudinal direction, and subsequently cools the belt to maintain the stretched state. In this cooling, a plurality of V-belts are stretched between a pair of V-pulley vehicles, and water is cooled from a pore of a cooling water pipe onto a belt running at a constant speed to a predetermined temperature. (See FIG. 9). In this way, a V-belt having excellent dimensional stability after removal is manufactured.

[0004]

However, in the conventional V-belt press vulcanizing apparatus as described above, the belt temperature immediately after vulcanization has a step-like temperature distribution in all circumferential directions, The part immediately after is the highest, and the part that has been vulcanized first is the lowest. In other words, the temperature of the belt at the start of cooling varies over the entire circumference of the belt in each vulcanization order, and the subsequent cooling time is different, and the remaining temperature is different. However, in the cooling, since the high-temperature portion and the relatively low-temperature portion are conventionally cooled equally, the cooling of the high-temperature portion is particularly insufficient, and a total cooling time is required. For this reason, the cycle time for manufacturing the belt is long, which hinders the productivity, and because the cooling water is showered, the work environment is poor due to the scattering of water droplets and the integrity of peripheral devices is hindered.

An object of the present invention is to improve the above problems and shorten the belt cooling treatment time after vulcanization to improve productivity, and at the same time, improve the cooling means to suppress the generation of water droplets. It is an object of the present invention to provide a V-belt press vulcanizing apparatus and a press vulcanizing method capable of improving the environment and preventing equipment rust and reducing maintenance costs.

[0006]

According to a first aspect of the present invention, there is provided a V-belt press vulcanizing apparatus which includes a tension applying means and a traveling means, and which moves forward and backward between a cooling zone and a vulcanizing zone by a moving means. A press vulcanizing unit including a pair of V pulley wheels, a hot platen for pressing upper and lower rows of a plurality of belts suspended between the pair of V pulley wheels with a hot mold, and a belt cooling unit including booth means. And a part. This allows the cooling space to be isolated from the surroundings, so that the cool air can be used effectively. At the same time, scattering of water droplets can be prevented, and an exhaust system can be easily installed locally.

According to a second aspect of the present invention, there is provided an apparatus for press-vulcanizing and molding a V-belt according to the first aspect, wherein the traveling means of the pair of V-pulley wheels is capable of constantly detecting the temperature of the belt and providing an adjusting means so as to be able to travel freely. It is. This makes it possible to detect the belt temperature distribution realistically and adjust the running speed of the belt passing through the cooling unit. In other words, the high temperature part of the belt can be cooled locally and intensively based on the belt temperature, so that the cooling of the vulcanized belt whose temperature varies stepwise on the circumference of the belt according to the vulcanization order is differentially adjusted. Thus, cooling to a uniform temperature can be performed easily, accurately and quickly without controlling the performance capacity of the cooling source.

According to a third aspect of the present invention, in the V-belt press vulcanization molding apparatus according to the first aspect, the belt cooling unit provided with the booth means is provided with at least mist water spray and cool air introduction. As a result, the fog water that has touched the high-temperature portion evaporates and evaporates instantly, and there is no scattering of water. At the same time, since the upper spray can be easily performed without scattering, cooling can be suitably performed from the back of the belt. Therefore, excessive cooling water can be prevented and running loss is small.

In a V-belt press vulcanization molding apparatus according to a fourth aspect, a plurality of unvulcanized V-belts are suspended between a pair of V-pulley vehicles, and the V-belts in respective upper and lower rows are sandwiched between hot dies. Press vulcanizing and shift the position multiple times in order to vulcanize the entire circumference,
Subsequently, the belt is stretched between a pair of V-pulley vehicles, and while traveling between the V-pulley vehicles, a cooling booth is used to simultaneously cool the belt from the front and back. As a result, the cooling contact area can be cooled not only on the belt upper surface but also on the trapezoidal bottom surface side, and the cooling capacity can be covered.

According to a fifth aspect of the present invention, there is provided a V-belt press vulcanization molding method according to the fourth aspect, wherein the belt traveling speed is controlled by constantly detecting the temperature of the belt that is stretched between the pair of V-pulley wheels and runs while cooling. It is what we did. This allows
The cooling step of the belt together with the apparatus of the first aspect can perform cooling based on the temperature of the belt. That is, since the high-temperature portion of the belt can be locally and intensively cooled, the cooling time can be shortened, and the belt can be optimally adapted to each size, and can be accurately cooled to a uniform temperature.

This is performed by pushing and pulling the longitudinal movement table 21.

Each axle of the V-pulley wheel 5 is connected to a beam member 34 and both ends are supported by bearings so as to withstand belt tension. However, the bearing on the near side is the loading / unloading side of the V-belt 2, and can be opened by pushing and pulling and swinging the connecting arm 36.

As shown in FIG. 9, the temperature distribution of
A step-like temperature configuration is set between 40 ° C. and 40 ° C. at the completion of cooling, depending on the vulcanization order.

The V-belt 2 having such a stepwise temperature distribution is set to a predetermined distance between the axes and cooled in a short time to a take-out temperature (40 ° C. uniform). Is made longer at higher temperature locations, that is, the running speed of the V-belt 2 is reduced, and the total cooling time is shortened.

A method for adjusting the running speed of the belt by detecting the temperature of the belt in real time will be described with reference to FIG. For example, FIG. 9 shows a press platen temperature of 148 ° C.
The figure shows a case where the surface temperature of the belt is measured when vulcanizing is performed for one round with a vulcanizing interval of 20 minutes and the vulcanizing position is shifted four times in total and moved to the cooling zone z1.

When b is equal to or greater than T1, the vehicle travels at the traveling speed Vb of V1 m / min (a traveling command is given to the driver of the rotary motor). When Tb is equal to or less than T1, the traveling speed Vb is selected from V2, V3, and V4 based on the determination values of T2, T3, and T4, and the traveling speed Vb is adjusted so as to be able to travel freely. When the predetermined cooling temperature approaches 40 ° C. and Tb becomes T4 or less, the traveling speed Vb is reduced to Vf.
