The present invention will be described in more detail below with reference to the accompanying drawings which exemplify the embodiments of the present invention.

1 to 8 of the accompanying drawings, in their entirety,
1 illustrates an essential part of an apparatus for carrying out the method according to the invention, i.e., but not limited to, an apparatus for producing corrugated sheet bodies, for example fiber reinforced cement corrugated sheets. That is, the running type rail 2 of the vehicle 1 provided in front of and on the side of the press type exchange vehicle 1 and the plate press machine 3 and the chain transmission arranged between the rail 2 and the front portion of the plate press machine 3. Member 4 is visible (see mainly Figures 1 and 2). The chain transmission member 4 is often understood as a term encompassing a belt transmission member and similar transmission members. From FIGS. 1 and 2 it can be seen that the press-type exchange vehicle 1 has a lifting device 5 with a hydraulic drive 6. This can be thought of as a so-called piston cylinder device. The hydraulic drive device 6 of the lifting device 5 is
It may be connected to a hydraulic drive system for a plate press not shown. Of course, it may be configured as a separate hydraulic device. Press tool interchanging vehicle 1 is provided with a device for the precise position for receiving a press-type packets to its being found, the press lower mold 8 and the upper mold 9 in this packet 7 is positionally accurate Is bound to. Such an arrangement, the press tool interchanging vehicle 1, the chain transmission member 4, the further connecting rod 10 optionally also position
An arrangement means, for example, a strike belonging to the plate press machine 3.
In the plate press machine 3 in the open state,
The press lower mold 8 and the upper mold 9 are adjustable so that they can be accurately attached and detached . This position or state is shown in FIGS. Depending on other arrangements and configurations of the chain transmission member 4, it is not absolutely necessary, but in the present invention, it is preferable to provide the connecting rod 10 for mutual connection. This connecting rod 10 has a length adjusting device 11.

Referring to FIGS. 1 to 8, a lower die 8 and an upper die 9 are further provided, which are provided with pressing surfaces which complement each other in a wavy shape and mutually engage with each other, and which can abut against a pressing die packet. It is recognized that the processing for combining and dismantling the press-type aggregates is performed independently. First, the press-type exchange vehicle 1 described above having a suitable hydraulic driving device 6, the plate press before lateral departure stations in an open state 12
It is necessary to be able to start from and return to here. The press type exchange vehicle 1 extends from this departure station to the front of the plate press machine 3 and travels by the above-mentioned chain transmission member 4 connected to the surface opposite to the plate press machine 3. In order to assemble and combine the press-type aggregates, the corresponding press-type packets 7 are
At the departure station 12, it is accurately placed on the press-type exchange vehicle 1. The standby vehicle 1 accurately enters the plate press machine 3 in an open state. This position is shown in Figure 1.
1 and 2, the press-type packet 7 is not shown in the positions occupied by the type-changing vehicle 1 shown in FIGS. The hydraulic drive device 6 of the lifting device 5 in the mold exchange vehicle 1 is connected to the hydraulic drive system of the plate press machine, and the mold exchange vehicle 1 together with the press die packet is opened by the lifting device 5 in the press machine 3 It is Agekyo the inner, contacting the pulp-less upper mold 9 put to work crossbeam 13.
The press-type packet 7 should be placed on the side of the work at that time or thereafter.
Combined with digit 13. This point will be described later in detail.
The mold exchange vehicle 1 is separated from the press-type packet 7 and is lowered by the lifting device 5. As a result, the model exchange vehicle 1 can return to the departure station 12. This is followed, press-type packet, work crossbeam 13
Is lowered until it comes into contact with the lower press die 8 on the press disk 14. Lower press die 8, the press disk and are combined and freed Ri good working crossbeam 1 3. The upper press die 9 is left connected to the work cross beam 13.
The plate press 3 is thus ready for operation.

With such a structure of the press type aggregates 8 and 9, finally, the reverse process of the above process is performed. In the illustrated embodiment, when the mold change vehicle 1 enters the plate press machine 3 in an open state, the press mold packet 7 is first connected to the chain transmission member 4.
The chain transmission member 4 is thus inserted in the open plate press 3 into a floor recess which cannot be directly acted upon by the chain transmission member 4. Therefore, the above-mentioned connecting rod 10 is now inserted between the mold changing vehicle 1 and the chain transmission member 4, and thus the floor surface recessed portion is inserted by the chain transmission member 4 through the interposing portion of the connecting rod 10. Can be acted on jointly. When dismantling or removing the press-type aggregate, the reverse process described above is performed.

The press die packet 7 in this embodiment is joined to the work crossbeam in various ways after the die exchange vehicle has entered the plate press 3 in the open state. To this end, it can be guided, for example, by means of a cylinder piston device with a hammerhead piston rod 15 into the corresponding receiving recess 16 of the upper die 9 or the lower die 8 . This configuration can be recognized from FIG. That is, FIG. 7 shows a press bottom fixed on the press disk 14 by an appropriate fixing member 17.
The mold 8 is shown, and further the press upper mold 9 fixed to the work cross beam 13 is shown. In the left side of FIG. 7, the hammer head piston rod 15 is extended to lower the press.
It can be immediately recognized that the hammerhead can enter into the hammerhead receiving recess 16 provided in the die 8 and be received by the recess by corresponding actuation of the cylinder piston device and stick to the upper press die 9. A large number of such engagement devices, which can take the form of hammerhead piston rods 15, are provided over the entire length of the plate pressing machine 3, and thus over the entire length of the lower die 8 and the upper die 9, and perform the above-mentioned operations.

In FIG. 8, the structure on both sides of the plate pressing machine 3 is shown in a plan view. The plate press machine 3 then performs the original pressing process, and can understand FIG. 8 for each of the above-described components without re-explaining with reference to the preceding drawings.
