[Means for solving problems]
In order to achieve the above object, the preform heating transfer mechanism of the present invention includes a transfer member that holds a plurality of preforms side by side in the longitudinal direction.
A transport path for circulating and transporting the transport member and
In preform heating transport mechanism for chromatic heating means for heating the preforms held by the conveying member while transporting the transport path,
The transport path includes a linear outward path for transporting a plurality of transport members side by side in a direction orthogonal to the longitudinal direction of the transport member.
A linear return path that is arranged in parallel adjacent to the outward path and transports a plurality of transport members side by side in the direction opposite to the outward path .
Have,
The heating means is provided on both the outward path and the return path.

本発明においては、前記往路及び復路には、前記プリフォームを自転させるための自転用チェーンが配設され、
前記各搬送部材には、前記各プリフォームを保持して自転可能にされたプリフォーム保持部材が設けられ、
前記各プリフォーム保持部材は、連動手段により連動可能に連結され、かつ、前記搬送部材の長手方向両端部のプリフォーム保持部材には、前記自転用チェーンと噛合する自転用スプロケットが設けられていることが好ましい。 In the present invention, a rotation chain for rotating the preform is provided on the outward path and the return path.
Wherein the respective conveyance members, preform holding member which is in capable of rotating while holding the respective preform is provided,
The preform holding members are interlocked with each other by interlocking means, and the preform holding members at both ends in the longitudinal direction of the transport member are provided with a rotation sprocket that meshes with the rotation chain. Is preferable.

このような構成とすることで、各プリフォーム保持部材を自転させるための機構を搬送路側に設ける必要が無く、その分搬送路側のスペースを狭めることができ、省スペース化が可能となる。 With such a configuration, it is not necessary to provide a conveyance path side of the mechanism for rotating the respective preform holding member, it is possible to narrow the space of that amount conveyance path side, it is possible to save space ..
