Accordingly, the hook 162 of the mold conveyance bushing 158 is movable up to the extension guide rail 404.

As a result, the mold transport bushing 158 serves as a means for transporting the mold M into or out of the horizontal injection molding machine 15, and the mold transport bushing 158 is used to transport the horizontal injection molding machine 15 and the setup cart 10. The mold M is exchanged between the two.

A setup change signal is output from the mold setup change centralized control panel G4 to the preliminary temperature control control panel and the trolley control panel, and a series of setup operations are started.

First, the first setup truck IO moves to the stocker 6 that stores the mold M (hereinafter referred to as the wage mold) to be newly set for the molding machine 15, and is loaded onto the setup truck IO. The wage type M is transferred from the stocker 6 to the table 106 of the setup cart 10 by the hooker 108. In addition, a conveyance roller (not shown) is rotatably disposed on the floor of the stocker 6, and when transferring the mold M between the setup cart 10 and the stocker 6, The mold M is made movable on the conveyance roller.

Next, the setup truck 10 transports the wage mold M to the preliminary temperature control station 4, and here too, the wage mold M is set in the preliminary temperature control station 4 by the hooker 108 mounted on the setup truck IO. This preliminary temperature control station 4
Preheating is performed.

When the preheating of the wage mold M is completed, the wage mold M is again transferred from the pre-temperature control station 4 to the setup vehicle 10 by the hooker 108 mounted on the setup truck 10 and transported to the molding machine 15. be done.

When the setup trolley IO arrives at the molding machine 15, the mold M in the molding machine 15 (hereinafter referred to as the old mold) is moved to the setup trolley 1 by a hook 162 attached to the molding machine 15.
0 is pushed out to the empty table 106.

After this old mold is loaded on the table 106, the table 106 moves on the setup trolley 10 and molds the wage mold M a1.
Preparations are made to set it to 5. Then table lO
The cutting die M loaded on the mold fi 15 is pulled into the mold alS by the hook 162 attached to the mold fi 15 and set in the molding machine 15, thereby completing a series of setup changes.

The old mold M loaded on setup trolley lO is
O and stored in an empty stocker 6, or if maintenance is required, it is transported from the molding machine automatic operation area C to the mold tool maintenance area A.

In the molding machine automatic operation area C, when maintenance of the old mold is required, the old mold M is transported to the reversing machine 30 by the setup cart 10.

The transfer of the old mold M from the setup truck IO to the reversing machine 30 is carried out by the cooperation of the hooker 108 mounted on the setup truck 10 and the rotational drive of the long roller 318 of the reversing machine 30. It will be done. At this time, the reversing machine 30 determines whether the mold requiring maintenance is the fixed mold M-a or the movable mold M-a.
Mold support surface 3 that takes the old mold M depending on whether
14 is selected in advance, and before the old mold M is received, the mold support surface 314 is set.

The reversing machine 30 inverts the old mold M, which has been picked up side by side from the setup cart 10, by 90 degrees, so that the fixed mold M-a and the movable mold M-b are in a vertical position. A conversion is made. In the old mold M after the attitude change, those requiring maintenance will be located on top.

After the attitude is changed by the reversing machine 30 in this way, the old mold M is transferred from the reversing Wt30 to the transport vehicle 20 by rotating the long roller 318 of the reversing @30 and the roller 201 of the transport vehicle 20. done by. Transport trolley 20
The old mold M placed thereon is transported to the crane yard D by the transport vehicle 20, where necessary maintenance is performed.

Mold M after maintenance is completed in molding machine automatic operation area C
Since the case of conveying to the above case is the reverse of the above case, the explanation thereof will be omitted.

On the other hand, in the molding machine automatic operation area C', when maintenance of the old mold is required, the old mold M is transported by the setup trolley 10' to the connection part between the rails 12 and 22, and then At the connection part, the old mold M is transferred from the setup truck 10' to the transfer truck 20. This transfer is.

This is carried out by a predetermined mechanism of the transport vehicle 20 and the setup vehicle 10'.

When the old mold M is transferred to the transport vehicle 20, the old mold M
The old mold M is transported to the reversing machine 30 by the transport vehicle 20, and the old mold M is transferred to the reversing machine 30 by the rotation drive of the roller 201 of the transport vehicle 20 and the long roller 318 of the reversing machine 30. 30, as described above, there is a 0-reversing machine that changes the posture of the fixed mold M-a and the movable mold M-b so that they are placed in the upper and lower positions so that the part that requires maintenance is located at the top. After completing the posture change of the old mold M at 30, the old mold M is moved again to the long roller 31 of the reversing machine 30.
8 and the rollers 201 of the transport vehicle 20 are rotated to transfer it to the transport vehicle 20. Thereafter, the old mold M is transported to the crane yard D by the transport vehicle 20, and is subjected to necessary maintenance.

After the maintenance is completed, mold M will move to molding machine automatic operation area C.
', but since this case is the opposite of the above case, its explanation will be omitted.

In this way, even if two molding machine automatic operation areas c and c' are provided, the attitude of the mold M can be changed with one reversing machine.

When a molded product is molded in each horizontal injection molding machine 15.15', each molded product is transferred to the molded product take-out line N,
The molded products are taken out from the molding machine 15, 15' by the molding machine 15, 15' and supplied to the molded product delivery line L, which sequentially transports each molded product to the stockyard 504.

Even if there are a pair of molding machine lines 15 and 15' in this way, each molded product is carried out by one molded product discharge line L.

(Effects of the Invention) As described above, the present invention allows molded products to be supplied from each molding machine to the molded product delivery line via the molded product take-out line, and one molded product delivery line is sufficient. The space required by the I& shaped product delivery line can be minimized, and the configuration related to molded product delivery can be made as simple as possible.
