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

First, the setup carriage 10 moves to the stocker 6 which stores the mold M (hereinafter referred to as a new mold) that is newly set in the molding machine 15, and is mounted on the setup carriage 10. Hooker
By 108, the new mold M is transferred from the stocker 6 to the table 106 of the setup carriage 10. In addition, the stocker 6
A transfer roller (not shown) is rotatably arranged on the floor surface, and when the mold M is transferred between the setup carriage 10 and the stocker 6, the mold M moves above the transfer roller. It is supposed to be movable.

Next, the setup carriage 10 conveys the new mold M to the preliminary temperature control station 4, and again, the new mold M is moved to the preliminary temperature control station 4 by the hooker 108 mounted on the setup carriage 10.
It is set inside and preheated at this preliminary temperature control station 4.

When the preheating of the new mold M is completed, the new mold M is transferred from the preliminary temperature control station 4 to the set-up car 10 again by the hooker 108 on which the set-up car 10 is mounted, and the molding machine 15 is reached. Be transported.

When the setup carriage 10 arrives at the molding machine 15, this time, the molding machine 15
A mold M (hereinafter, referred to as an old mold) in the molding machine 15 is pushed out to the vacant table 106 of the setup carriage 10 by a hook 162 attached to the. After the old mold is loaded on the table 106, the table 106 moves on the setup carriage 10 to prepare for setting the new mold M on the molding machine 15. After that, the new mold M loaded on the table 106
Is drawn into the molding machine 15 by a hook 162 attached to the molding machine 15 and set in the molding machine 15, whereby a series of setup changes is completed.

The old mold M loaded on the setup carriage 10 is transported by the setup carriage 10 and stored in the vacant stocker 6,
Alternatively, when maintenance is required, the molding machine automatic operation area C is conveyed to the mold tool maintenance area A.

Transfer of dies between mold tool maintenance area A and molding machine automatic operation area C, C'In the molding machine automatic operation area C, when maintenance of the old mold is required, the old mold M is set up. It is conveyed to the reversing machine 30 by the carriage 10.

The transfer of the old mold M from the setup carriage 10 to the reversing machine 30 is performed by the cooperation of the hooker 108 mounted on the setup carriage 10 and the rotation of the long roller 318 of the reversing machine 30. It
At this time, the reversing machine 30 receives the old mold M according to whether the mold requiring maintenance is the fixed mold Ma or the movable mold Mb, and the mold supporting surface 314. Is preselected and before the old die M is received, the die support surface 314
Is set.

In the reversing machine 30, the old mold M received from the setup carriage 10 in a side-by-side state is reversed by 90 degrees, and the posture change in which the fixed mold Ma and the movable mold Mb are placed in the upper and lower states is performed. Done. After the posture is changed, the old mold M, which requires maintenance, is positioned above.

After the posture is changed by the reversing machine 30 as described above, the old die M is transferred from the reversing machine 30 to the carrier vehicle 20 by the reversing machine.
This is performed by rotationally driving the long roller 318 of 30 and the roller 201 of the carriage 20. Old mold M placed on the carrier 20
Is transported to the crane yard D by the transport carriage 20 and subjected to necessary maintenance.

Mold M after maintenance is completed
The case of transporting to is the reverse of the above case, and therefore its description is 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 conveyed by the setup carriage 10' to the connecting portion between the rail 12 and the rail 22, and At the connecting part, the old mold M is a setup truck 1
It can be transferred from 0'to the carriage 20. This transfer is performed by a predetermined mechanism of the transport carriage 20 and the setup carriage 10 '.

When the old mold M is transferred to the carriage 20, the old mold M
Is transported by the transport carriage 20 to the reversing machine 30, and the old mold M is the roller 201 of the transport carriage 20 and the long roller 3 of the reversing machine 30.
It is transferred to the reversing machine 30 by rotational drive with 18. In the reversing machine 30, as described above, the fixed mold Ma and the movable mold M are placed so that the one requiring maintenance is positioned above.
Attitude conversion is performed such that −b and the upper and lower sides are in the upper and lower states. Reversing machine
After the attitude change of the old die M in 30 is completed, the old die M is again in the long roller 318 of the reversing machine 30 and the roller 201 of the carrier 20.
It can be transferred to the carriage 20 by the rotation drive of and. Then, after that, the old mold M is transported to the crane yard D by the transport carriage 20 and subjected to necessary maintenance.

After the maintenance is completed, the mold M is conveyed again to the molding machine automatic operation area C ', but in this case, the description is omitted because it is the opposite of the above case.

As described above, even if two molding machine automatic operation areas C and C ′ are provided, the posture of the mold M can be changed by one reversing machine.

Carrying out the molded product When the molded product is molded in each horizontal injection molding machine 15, 15 ', each molded product is taken out from the molding machine 15, 15' by the above-mentioned molded product take-out line N, N ', and molded. Product unloading line L
The molded product unloading line L sequentially conveys each molded product to the stockyard 504.

Even if there is a pair of molding machine lines 15 and 15 'as described above, each molded product is carried out by one molded product carry-out line L.

(Effect of the invention) As described above, the present invention can supply the molded product from each molding machine to the molded product unloading line through the molded product unloading line, and since only one molded product unloading line is required, It is possible to reduce the space required for the molded product unloading line as much as possible, and to simplify the configuration related to the unloading of the molded product as much as possible.
