However, holding the cylindrical parison 2 has a complicated holding mechanism, and wrinkles and the like are generated in the parison 2 when transported.

In addition, as shown in FIG. 12, two sheet-like parisons 2 are extruded from two slit-shaped dies and conveyed to the blow molding die 240 by the parison holding member 230 of the parison conveying device 210. And there exists a thing which introduce | transduces the parison 2 between the two division | segmentation molds 241 and the intermediate mold 242 of the blow molding mold 240, respectively, and shape | molds a hollow molded object (for example, refer patent document 2).

However, in this case, since the two sheet-like parisons 2 are extruded from the two slit-shaped dies, the structure of the parison extruder is complicated.
Moreover, there exists what divides | segments so that the cylindrical parison 2 may be extruded and it may be made into the two semi-cylindrical parison 2 while extruding. Immediately after the extrusion, the semicylindrical parison 2 is cut into a flat sheet using a pulling roller, and is then conveyed by a parison conveying device. In this case, when the two semicylindrical parisons 2 are formed into flat sheets using the pulling rollers, the parisons 2 from the cutting of the parison 2 to the pulling rollers contribute to the formation of the hollow body.

As shown in FIG. 2, a robot attachment portion 38 is formed on the central holding frame 37. The parison coupling member 20 is coupled to the robot mounting portion 38, and the parison holding member 30 is moved by the robot arm 13 so that the parison 2 can be conveyed, and the upper parison adsorption member 31 and the lower parison adsorption member 33 are driven. Can be made.

Next, the cutting and conveyance of the parison 2 will be described.
As shown in FIG. 1, the parison 2 extruded from the extrusion head 1 is held by a parison holding member 30, cut by a parison cutting member 32, held by a parison holding member 30, and then hollowed by a robot 15. It is conveyed to a molding die (not shown). Hereinafter, the cutting and conveyance will be described in detail.

The parison 2 extruded cylindrically from the extrusion head 1 is separated into two semicylindrical shapes immediately after extrusion. The two semi-cylindrical parisons 2 are opened by a roller or the like and opened in a flat plate shape, and then sandwiched by two upper parison adsorption bars 31a provided on each upper parison adsorption member 31 shown in FIG. . 3 shows the upper parison adsorbing member 31 on the right side of the parison holding member 30 shown in FIG. 2, but the same applies to the upper parison adsorbing member 31 on the left side.
The upper parison suction bar 31a is attached to the upper parison suction bar attachment portion 31c.

One end of the upper parison suction bar mounting portion 31c to which the upper parison suction bar 31a is attached is rotatably held by the upper parison suction member rotating shaft 31e, and the other tip of the upper parison suction bar 31a is opened and closed. Since the two upper parison adsorbing bars 31a are opened, the upper part of the parison 2 extruded from the extrusion head 1 can be held.

Since two upper parison adsorbing members 31 are attached to the left and right of the upper portion of the parison holding member 30, the two parisons 2 separated are held by the left and right upper parison adsorbing members 31, respectively.
As shown in FIG. 5, a parison cutting member 32 is attached to each of the left and right upper parison adsorbing members 31. After being held by the left and right upper parison suction members 31, the parison slide cutting blade 32 a of the parison cutting member 32 slides along the upper parison suction bar mounting portion 31 c to cut the parison 2.

The cut parison 2 is adsorbed by upper parison adsorbing pads 31b provided on the upper parison adsorbing bar 31a. The upper parison adsorbing pad 31b is provided with an upper parison adsorbing hole 31f in the center. Air is sucked from the upper parison adsorbing hole 31 f of the upper parison adsorbing pad 31 b to hold the parison 2. The upper parison suction hole 31 f is connected to an air tank 11 that sucks air with the air hose 12.

When the parison 2 is held by the upper parison adsorption pad 31b, the parison 2 held between the two upper parison adsorption bars 31a slightly opens the two upper parison adsorption bars 31a and holds the parison 2 by the upper parison adsorption bar 31a. Is released. The parison 2 is sucked by the plurality of upper parison adsorbing pads 31b and does not shift. Further, when the parison 2 is sandwiched and transported by the upper parison adsorption bar 31a, the parison 2 may be wrinkled or waved, but the wrinkle or wave can be prevented by being adsorbed by the upper parison adsorption pad 31b. .

If the upper parison adsorbing pad 31b adsorbs without holding the parison 2, the portion where the parison 2 is held does not become thin. When the portion where the parison 2 is sandwiched becomes thin, the portion where the parison 2 is sandwiched cannot be used for molding at the time of molding in the hollow body molding die, but is held by the upper parison adsorption pad 31b. Since the parison 2 does not become thin, it can be used for molding in the cavity of the hollow body molding die, and waste of the material of the parison 2 is reduced.

The two parisons 2 held by the upper parison adsorbing pad 31b of the upper parison adsorbing member 31 can be provided with lower parison adsorbing members 33 at the lower portions corresponding to the two upper parison adsorbing members 31, respectively. In this case, as shown in FIG. 6, the two parisons 2 can be transported to the hollow body mold by holding the upper and lower parison adsorbing members 31 and the lower parison adsorbing member 33 on the upper and lower sides, respectively. The parison 2 does not become wrinkles or deforms during conveyance, and can be reliably conveyed to a position facing the cavity of the hollow body molding die.

Similarly to the upper parison adsorbing member 31, the lower parison adsorbing member 33 can be provided with a lower parison adsorbing bar 33a. The lower parison suction bar 33a is attached to the lower parison suction bar attachment portion 33c. The lower parison adsorption bar 33a can be provided with a lower parison adsorption pad 33b.

The tip of the robot arm 13 is attached to the robot attachment portion 38 of the parison holding member 30 by the parison connecting member 20. For this reason, the parison holding member 30 holding the two parisons 2 is inserted between the two split molds in which the hollow body molding die is opened to the left and right by the robot arm 13 until the position facing the cavity. Be transported.
The parison connecting member 20 is integrally attached with a connecting member for supplying signals and energy for driving various members attached to the parison holding member 30.

An air hose 12 for sending air for driving the upper parison adsorbing member 31 and an air hose 12 for sucking air from the upper parison adsorbing hole 31f are attached to the robot arm 13. The air hose 12 is supplied with air from the air tank 11 or sucks air and is connected to a valve plate 14 attached to the robot arm 13. The air hose 12 is further extended from the valve plate 14 and reaches the upper parison adsorbing pad 31 b of the upper parison adsorbing member 31.

The parison holding member 30 inserted between the two split molds rotates the rotating rail 37c to bring the upper parison adsorbing member 31 and the lower parison adsorbing member 33 attached to the upper slide rail 34 close to or away from each other. The parison 2 is moved so as to be close to the two split cavities.
Thereafter, the parison 2 is sucked and adsorbed and held in the split cavity.

When the parison 2 is adsorbed in the split cavity, the upper parison adsorbing pad 31b of the upper parison adsorbing bar 31a is sucked and the holding of the parison 2 is released. At this time, air can be blown out from the upper parison adsorption hole 31f. In this case, the parison 2 can be reliably and quickly separated from the upper parison adsorption pad 31b.
The split mold is closed together with the parison 2 adsorbed in the split mold cavity to form a hollow body.
