に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for sealing the ends of unvulcanized rubber hoses, and more specifically, the present invention relates to a method and apparatus for sealing the ends of unvulcanized rubber hoses, and more specifically, by dry heat vulcanizing only the ends before vulcanizing the entire rubber hose, hose reinforcement is achieved. The present invention relates to a method and apparatus for sealing an end of an unvulcanized rubber hose, in which a yarn layer is wrapped in vulcanized rubber to prevent moisture and heat deterioration during vulcanization of the entire hose.

等を発生させる原因となつていた。 In order to manufacture rubber hoses, a method is used in which an unvulcanized rubber hose is manufactured and then heated and vulcanized. However, since this heat vulcanization is usually performed using pressurized steam or hot water, the steam or hot water penetrates into the reinforcing thread layer at the end of the hose, degrading the reinforcing thread layer. In order to prevent moisture and heat deterioration of this reinforcing thread layer, it is conventional to apply adhesive evenly to the end of an unvulcanized rubber hose with a spatula, and then to prevent the adhesive from staining the outside surface of other hoses, cover the applied area with a cloth. The end of the hose was sealed. However, such operations are manual, labor-intensive, and variations can result in incomplete seals and the possibility that steam or hot water may leak into the hose end during vulcanization. The reinforcing thread layer penetrates into the reinforcing thread layer, causing moisture-heat deterioration of the reinforcing thread layer and peeling of the cover rubber from the inner tube of the hose.

本発明はこのような従来技術の欠点を解消する
ため検討された結果、得られたものである。 The present invention was obtained as a result of studies to eliminate such drawbacks of the prior art.

A method for sealing the end of an unvulcanized rubber hose, characterized by a core rod for inserting the end of the unvulcanized rubber hose and heating the end, and a method for heating the end of the rubber hose by pressurizing it from the outside. The gist is a sealing device for the end of an unvulcanized rubber hose consisting of a mold and a mold.

The sealing device of the present invention includes a core rod 2 standing upright in the center of a sealing stand 17, a pair of formworks 3 and 4 having semi-cylindrical recesses around the core rod 2, and the formworks 3 and 4.
a pneumatic cylinder 7 that opens and closes via a fulcrum 5;
It is comprised of a solenoid valve 6 and a timer 14 for operating this.

を防止する事が出来る。 A core rod 2 is inserted into the center hole of the unvulcanized rubber hose end 1, and both sides thereof are attached to the unvulcanized rubber hose end 1.
Formworks 3 and 4 having semi-cylindrical recesses slightly smaller than the outer diameter of the molds are pressurized facing each other by a solenoid valve 6 and a pneumatic cylinder 7 with a fulcrum 5 as the center. The formworks 3, 4 and the core rod 2 are heated by heaters 8, 9, 10 built into them, and their temperatures are controlled by temperature sensors 11, 12, 13, respectively, and the unvulcanized rubber hose is kept in this state for a certain period of time. After dry heat vulcanizing the end portion 1, formworks 3 and 4
is automatically opened by a timer 14, a solenoid valve 6 and a pneumatic cylinder 7. When the unvulcanized rubber hose end 1 is pulled out, as shown in FIG. 3, the reinforcing thread layer 15 is completely wrapped in the vulcanized rubber 16 at the tip of the unvulcanized rubber hose end 1, and moisture and heat deterioration occurs during vulcanization. can be prevented.

る。 In other words, this sealing process is performed prior to the wet heat vulcanization process of the entire unvulcanized rubber hose, and this end sealing process is completely cured by the heat of the heater built into the formwork and core rod. The process is carried out by dry heat without steam or hot water coming into contact with the reinforcing yarn layer. the result,
The reinforcing thread layer at the end is wrapped in thick rubber and is completely isolated from the outside air. After that, the entire rubber hose is vulcanized using steam or hot water, but at that time, the end of the rubber hose is completely sealed as shown in Figure 3, so steam or hot water will not penetrate into the reinforcing yarn layer. This prevents moisture and heat deterioration or separation of the inner tube from the cover rubber.

効果はより完全なものとなる。 Moreover, if adhesive is applied to the end of the rubber hose before inserting it into the core rod of the sealing device, the sealing effect will be more complete.

め、次のようなすぐれた利点を有する。 As explained above, the method of the present invention is a sealing method in which only the ends of the unvulcanized rubber hose are dry heat vulcanized before the entirety of the unvulcanized rubber hose is vulcanized, and the apparatus of the present invention This sealing device has a heatable core rod into which the rubber hose is inserted, and a heatable formwork that vulcanizes the end of the rubber hose from the outside, so it has the following advantages.

(1) 加硫時に接着剤をゴムホース端部へ塗布する
必要がなく、作業量が削減される。(1) There is no need to apply adhesive to the end of the rubber hose during vulcanization, reducing the amount of work.

(2) 端部の乾熱加硫を自動的に行なうため、手作

カバーゴム剥離が完全に阻止される。(2) Because the dry heat vulcanization of the ends is performed automatically, the sealing accuracy is better than manual adhesive application, and there is no need to worry about wet heat deterioration of the reinforcing thread layer and the inner tube of the hose.
Cover rubber peeling is completely prevented.

(3) 芯棒と型枠とを主とした装置であるため、比
