[0057] Hereinafter, a first embodiment will be described with reference to the drawings.
[0058] (Hot pressing device)
[0059] First, the configuration of the heat press apparatus 10 according to the first embodiment will be described. Such as figure 1 As shown, the hot pressing device 10 includes a workbench 12 , a heating furnace 14 , a delivery workbench 16 , a first press 18 , a second press 20 and a controller 22 .
[0060] The first press 18 and the second press 20 are arranged away from each other in the horizontal direction, and the transfer table 16 is arranged between the first press 18 and the second press 20 . The first end of the conveyance table 16 is connected to the inlet and outlet 14A of the heating furnace 14 , and the table 12 is disposed on the second end side of the conveyance table 16 . The blank 24 before being press-worked is placed on the table 12 .
[0061] The heat press apparatus 10 executes a first heating step, a first pressing step, a seco...

[0189] Figure 12 and Figure 13 It is a figure which shows 2nd Embodiment. In the second embodiment, the same reference numerals are assigned to the same or equivalent parts as those in the first embodiment to omit description, and only the parts different from the first embodiment will be described.
[0190] In 2nd Embodiment, the conveyance table 16 of 1st Embodiment is changed into the conveyance stage 140 which does not have the roller 26. As shown in FIG. The transport table 140 is connected to the entrance and exit of the heating furnace 14 . The top plate surface 142 of the conveyance table 140 is formed flat, and on the top plate surface 142, the groove 16B of the conveyance table 16 of the first embodiment (refer to figure 2 , image 3 ) is formed with grooves 144 at corresponding positions.
[0191] The width 146 of each slot 144 is wider than the width 78 of the pair of arms 70 of the workpiece transport tool 46 . That is, the width 78 of the rotational shaf...

[0196] Figure 14 and Figure 15 It is a figure which shows 3rd Embodiment. In the third embodiment, the same reference numerals are assigned to the same or equivalent parts as those in the first embodiment to omit description, and only the parts different from the first embodiment will be described.
[0197] In the third embodiment, a shape sensor 150 and a temperature sensor 152 are provided on the base frame 48 . In addition, the pair of first claws 100 and the pair of second claws 102 are provided with positioning guides 154 for positioning the holding position of the workpiece.
[0198] The shape sensor 150 provided on the edge side of the base frame 48 is a sensor for determining the shape of the workpiece, and an example thereof is a distance sensor for measuring the distance to the workpiece. The distance sensor determines that the workpiece is a blank 24 when the distance to the workpiece is short, and determines that the workpiece is a molded product (eg, primary ...
