Next, the operation will be explained.

Workpieces 3, 3 made of heated fiber-reinforced plastic are sent in parallel from a heating furnace 1 onto each conveyor 2, 2. At this time, the elevating table 6 is lowered, so that the elevating table 6 comes into contact with the stopper 12 and, together with the movable table 7, is in an inclined position in which the conveyor 2 side is higher.

The above-mentioned workpiece 3 carried out by conveyors 2, 2,
3 is guided by shooters 5, 5 and placed on a lifting table 6 and a moving table 7. At this time,
Since the elevating table 6 and the moving table 7 are inclined so that the conveyor 2, 2 side is higher, even if the workpieces 3, 3 are made of stiff and soft fiber-reinforced plastic, there is no space between the conveyor 2, 2 and each table 6, 7. The works 3, 3 are smoothly placed on the respective tables 6, 7 without being deformed by being pinched or bent between the two.

At this time, the end position of each workpiece 3 in the transport direction is adjusted by the stopper 8. When stacking two works 3, 3, the cylinder device 9 is operated to position the movable table 7 on the lifting table 6. At this time, the workpiece 3 on the moving table 7 reverses the movable stopper 42 of the stopper mechanism 10. When the cylinder device 9 is operated in the reverse direction to return the movable table 7 to its original position, the workpiece 3 hits the movable stopper 42 and remains unmoved, overlapping the workpiece 3 on the lifting table 6.

Next, the lifting cylinder 11 is actuated to raise and lower the lifting table 6, and the lifting table 6 is moved away from the stopper 12, becomes horizontal by the spring 49, and stops at the upper limit position.

Next, the cable cylinder 16 is actuated to move the fork 15, and this fork 15 is moved to the table 6.
Transport the upper workpiece 3. Due to this movement of the fork 15, the guide 40 is pushed by the fork 15 and becomes horizontal, and the workpiece 3 is inserted between the upper and lower dies 22 and 17 of the press apparatus B together with the fork 15.
In this case, the movable stopper 52 is pushed by the workpiece 3 and escapes upward to allow the workpiece 3 to pass. After passing, the movable stopper 52 rotates due to its own weight and comes into contact with the left end surface of the workpiece 3.

Next, when the cable cylinder 16 is operated in reverse and the fork 15 is moved to the left, the workpiece 3 is left between the upper and lower dies 22 and 17 by the movable stopper 52, and at the same time the guide 40 is moved by the weight 21 to the two points shown in FIG. Rotate as shown by the chain line. Then upper mold 22
descends and forms the workpiece 3.

Note that in order to install the workpiece 3 in the mold, the stopper mechanism E is not limited to the above-described stopper mechanism. After being retracted, the stopper may be retracted from inside the mold.

7 to 10 are other embodiments of the present invention. In this case, in front of the lifting table 6,
Moving tables 7' and 7 are arranged on the rear side.
That is, cylinder devices 9', 9 are arranged in front and rear sides of the lifting table 6, the first moving table 7' is attached to the rod 33' of the cylinder device 9' on the front side, and the first moving table 7' is attached to the rod 33' of the cylinder device 9' on the front side. A second moving table 7 is attached to the rod 33 of the cylinder device 9.

A stopper mechanism 10' similar to the stopper mechanism 10 described above is provided at the front and rear sides of the lifting table 6.
10 are arranged.

The elevating table 6 is raised and lowered by an elevating cylinder 11 as in the above-described embodiment.

Then, from the state where the workpiece 3 is placed on each table 6, 7, 7', the rear cylinder device 9 is extended and the second fixed table 7 is placed above the lifting table 6, and the stopper mechanism The rear end of the workpiece 3 of the second movable table 7 is applied to the ten movable stoppers 42. In this state, the cylinder device 9 is contracted and the moving table 7 is moved backward,
The workpiece 3 is stacked on the workpiece 3 on the lifting table 6.

Next, the front cylinder device 9' is extended and the first movable table 7' is placed above the lifting table 6, and the movable stopper 42' of the stopper mechanism 10' is placed at the rear end of the workpiece 3 on the movable table 7'. Can be guessed. In this state, the cylinder device 9' is contracted, the moving table 7' is moved rearward, and the work 3 is stacked on top of the work 3.

As described in detail above, the present invention has a structure in which a workpiece 3 made of fiber-reinforced plastic heated in a heating furnace 1 is conveyed in parallel on the side of one of the conveyors 2 out of the plurality of conveyors 2, 2. Elevating table 6
can be raised and lowered from a workpiece receiving position lower than the conveyor 2 to a workpiece delivery position above the conveyor 2, and can be rotated freely from a horizontal position to an inclined position where the conveyor 2 side is higher, and in a horizontal position. Since the conveyor 2 is provided with a stopper 12 that contacts the lifting table 6 in the lowered state and tilts the lifting table 6 so that the conveyor 2 side is higher, the lifting table 6 in the lowered state The workpiece discharge height of the heating furnace 1 can be set to be sufficiently lower than the workpiece discharge height, and the workpiece 3 can be tilted so as to be connected to the shutter 5. As a result, the workpiece 3 discharged from the conveyor 2 corresponding to the elevating table 6 is not stiff. Even though it is a soft fiber-reinforced plastic, it can be smoothly placed on the lifting table 6 without being caught between the conveyor 2 and the lifting table 6, or bent and deformed between them.

Also, a moving table 7 is placed on the side of the lifting table 6 in the lowered state and on the side of the conveyance side of the other conveyor 2.
is movably provided in the same attitude as the lifting table 6 in the lowered state and above the lifting table 6 in the lowered state, and furthermore, between the lifting table 6 and the moving table 7, the moving table 7 is placed above the lifting table 6. Since the stopper mechanism 10 is provided to hold the workpiece 3 after moving to and to leave the workpiece 3 on the lifting table 6 when the moving table 7 moves out of the lifting table 6, the workpiece 3 is transferred from the conveyor 2 corresponding to the moving table 7. The workpiece 3 to be removed is transported to the conveyor 2 in the same way as the workpiece 3 corresponding to the lifting table 6.
The table 7 can be placed on the moving table 7 smoothly without being pinched between the moving table 7 or bent or deformed between them, and the table 7 can be moved onto the table 6 by actuating the cylinder device 9. Then, operate the cylinder device again to remove table 7.
By moving outward, the stopper mechanism 10
As a result, the workpiece 3 remains and the workpiece 3 on the table 6 is overlapped with the workpiece 3, so that the workpieces 3 can be reliably overlapped during transportation.
