Problems solved by technology

[0009] Therefore, when an attempt is made to prevent the horizontal rotation of the conveying member during conveyance by applying tension to the conveyer chain, the conveyer chain is worn and the life of the conveyer chain is shortened.
[0010] Furthermore, when the conveyor chain becomes longer due to wear and tear, the position of the conveyor components will also be misaligned, making it difficult to locate the conveyor components
Therefore, the management of the tension of the conveyor chain will become an important daily inspection item, increasing the workload of the forming operation manager

Abstract

A blow molding device comprising: a plurality of conveying parts holding a preform; a conveying chain for driving the conveying parts, fixing the plural conveying parts at predetermined intervals; ) to guide rails in the direction of the blow molding section (20). Each conveying member has a covering member or a posture restricting member that can contact each other to cover the space between the conveying members or to prevent the horizontal rotation of each conveying member during conveying. Alternatively, it is possible to prevent horizontal rotation of the conveying member while conveying without applying tension to the conveying chain.

Description

[0001] This application is a divisional application of the application number 99103682 filed by the applicant on March 12, 1999. 4. The application titled "Blow Molding Device". technical field [0002] The present invention relates to a blow molding device, in particular to a blow molding device for conveying molded products by a conveying member fixed on a conveying chain. Background technique [0003] As a blow molding machine that heats a preform made of synthetic resin and then blows molds it into a predetermined container shape, in "JP-A-8-132517" and "JP-A-8-224775" previously proposed by the applicant, It was shown in the Bulletin. [0004] On the blow molding machine, the conveying path of the preform is formed into a square shape, and the heating part and the blow molding part are arranged on the straight part, and the preform is conveyed to the heating part and the blow molding part along the conveying path by the conveying device. On the blow molding part. [0...
