- Each of the first gripping members 161 includes a pair of first chuck members 163 that are disposed on both the left and right outer sides of the preform 200 and have a chuck portion 163a for gripping the preform 200 at the tip portion.
- Each first chuck member 163 is supported by the support member 164 so as to be linearly movable.
- a rail portion 165 protrudes from the upper surface of each first chuck member 163, and a guide groove 166 is provided at the bottom surface of the support member 164.
- the rail portion 165 is engaged with the guide groove 166, whereby the first chuck member 163 is supported by the support member 164 so as to be linearly movable.
- These first chuck members 163 are configured to be movable by an air cylinder or the like (not shown), and a pair of first chuck members is obtained by linearly moving each first chuck member 163 toward the preform 200.
- Each preform 200 is pinched (gripped) by 163 (see FIGS. 5 and 6). *
- the second gripping member 162 is composed of a pair of second chuck members 167 having a chuck portion 167a for gripping the container handle at the tip end portion thereof.
- the pair of second gripping members 162 are respectively supported by the first chuck members 163 constituting the first gripping member 161.
- the second chuck member 167 is fixed to the side surface of the first chuck member 163 so that the second chuck member 167 is rotatable in the vertical direction on the side surface opposite to the chuck portion 167a. . *

From this state, when the first chuck member 163 is linearly moved and the preform 200 is gripped, the position of the support shaft 168 moves as the first chuck member 163 is driven to close. A force in the direction opposite to the moving direction of the first chuck member 163 acts from the arm portion 164a. As a result, the second chuck member 167 rotates downward by approximately 90 degrees with the linear movement of the first chuck member 163 to grip the container handle 20 (see FIGS. 5 and 6). . *
- the second chuck member 167 constituting the second gripping member 162 is used for linear movement of the first chuck member 163 constituting the first gripping member 161. It rotates in conjunction.
- the preform 200 and the container handle 20 can be simultaneously held by the first holding member 161 and the second holding member 162.
- a plurality of preforms 200 and a plurality of container handles 20 can be gripped simultaneously. Thereby, a molding cycle time can be shortened and manufacturing cost can be reduced.
- the second chuck member 167 is linked to the operation of the first chuck member 163 by a link mechanism. For this reason, compared with controlling the 1st chuck member 163 and the 2nd chuck member 167 separately, a structure can be simplified. *
- the gripping mechanism 160a having such a configuration at the preform receiving position P1
- the preforms 200 and the container handles 20 are gripped.
- the gripping mechanism portion 160a is slid to the blow molding position P2
- the preform 200 and the container handle are conveyed to the blow cavity mold 141 of the blow molding portion 140.
- a known mechanism may be adopted as a mechanism for sliding the first gripping member 161 and the second gripping member 162, and thus description thereof is omitted here.

As a result, the preform 200 and the container handle 20 are accommodated in the blow cavity mold 141. After that, as shown in FIG. 8, the first gripping member 161 and the second gripping member 162 are driven to open.
- each first chuck member 163 constituting the first gripping member 161 moves linearly to release the preform 200, and each second chuck member 167 constituting the second gripping member 162
- the container handle 20 is opened by rotating upward in conjunction with the linear movement of the one chuck member 163.
- the preform 200 is blow-molded by the blow cavity mold 141, whereby the container 1 with a handle (see FIG. 1) is formed.
- the molded container 1 with a handle is gripped by the gripping mechanism portion 160a as described above, and the gripped mechanism portion 160a is transported to the take-out position P3, whereby the container 1 with a handle is unloaded from the blow molding portion 140.
- grip mechanism conveyance part 160 is provided with two sets of holding
- the gripping mechanism 160a is configured to be able to change the pitch between the preforms 200 when the preform 200 and the container handle 20 are carried into the blow molding unit 140. That is, the gripping mechanism 160a grips the preforms 200 and the container handle 20 arranged at a relatively short pitch at the preform receiving position P1, but during the transport to the blow molding position P2, a predetermined blow is performed. The pitch of each preform 200 is adjusted so as to be the pitch. Further, when the molded container 1 with a handle is carried out, the gripping mechanism 160a moves without changing the pitch between the containers 1 with a handle.
