In order to manufacture a concrete product using the concrete product manufacturing apparatus 60 having the above configuration, first, on the conveyor line 1, the formwork 2 is conveyed by the roller conveyor 4 while being assembled, oiled, and concrete is poured into the mold. The frames 2 are sequentially transferred by the conveyor 11 to the form delivery end 11a. The formworks 2 are lifted up one by one by the formwork multi-stage stacking device 50 and stacked on the formwork cart 17 on the pre-curing formwork cart support section 41. At this time, the spacing between the molds 2 can be set to a desired small spacing. When a predetermined number of formworks 2 (nine in this embodiment) are placed on the formwork cart 17, the chain 44 of the roller conveyor 40 moves the empty formwork cart 17 on the formwork return conveyor 43 in the direction of arrow Z. By driving, the formwork cart 17 loaded with the formwork 2 on the pre-curing formwork cart support section 41 is pushed out and transferred to the front part of the pusher 45, and the lifting table 46 is raised and pushed by the pusher 45. , and transferred onto the traversing truck 20 on the end of the track 21. Traversing trolley 20
travels to the front of a predetermined curing chamber 15 while fixing and holding the formwork cart 17 with a stopper or the like (not shown), and pushes the formwork cart 17 into the curing chamber 15 with the push/pull tool 26 of the carry-in/out device 27. By repeating the above steps, one curing chamber 15 is filled with a predetermined plurality of formwork carts 17. At this time, since the adjacent formwork carts 17 come into contact with each other, the connecting device 34 connects the formwork carts 17. On the other hand, formwork carts 17 loaded with formwork 2 are transferred one by one from the curing chamber 15 where curing has been completed onto the transverse cart 20 parked in front of the entrance/exit 16. This transfer is carried out by engaging the push/pull tool 26 of the loading/unloading device 27 with the rear end 17a of the formwork cart 17 from the inside and pulling it out. When one formwork cart 17 is placed on the transverse cart 20, , the subsequent (inside the curing room) formwork cart 17 that has been pulled out in a connected state by the connection device 34.
Since the hook 32 is rotated upward by the cam plate 35, the connection is released, and the hook 32 is stopped at a position close to the entrance/exit 16 and remains in the curing chamber 15. In this way, one formwork cart 17 is placed on the traversing cart 20, and the puller 47
Formwork cart 1 is transferred to the front of
7 is then transferred onto the cured formwork cart support section 42 by the pushing machine 49, and the formwork 2 is transferred by the formwork lifting device 58.
are lifted up one by one and lowered onto the form receiving end 12a of the conveyor 12. This formwork 2 is transferred onto the roller conveyor 4 by the conveyor 12, and the formwork is disassembled and
After demolding and cleaning, it is used for the next concrete injection. Further, the empty formwork cart 17 from which the formwork 2 has been removed in the cured formwork cart support section 42 is circulated and supplied onto the uncured formwork cart support section 41 by the formwork cart return conveyor 43. On the other hand, the transverse carriage 20 that has unloaded the formwork carriage 17 onto the roller conveyor 40 moves to the entrance/exit 16 of the predetermined curing chamber 15 and pulls out the next formwork carriage 17, or the pusher 4
5 to the front position to receive the formwork truck 17 loaded with the formwork 2 filled with concrete and charge it into a new curing chamber 15.

In this way, the formwork 2 is disassembled and demolded separately from the formwork cart 17, so during curing, it is packed at small intervals on the formwork cart 17 and stacked in multiple stages. Therefore, a large number of formworks 2 can be loaded on the formwork cart 17, and therefore the curing room 15 requires only a small space, and only one relatively slow-speed traversing cart 20 is used to load the formwork cart 17. It can be used for both supplying to the curing chamber 15 and taking it out from the curing chamber 15.

In the above embodiment, the return of the empty formwork cart 17 from the cured formwork cart support section 42 to the uncured formwork cart support section 41 is carried out by the formwork cart return conveyor 43. 20 has the advantage that it only needs to transport the formwork cart 17 loaded with the formwork 2, so it can be operated at a lower speed, and there is also a greater degree of freedom in the operation program of the traversing cart 20. The installation of the formwork carriage return conveyor 43 may be omitted, and the empty formwork carriage 17 may be returned by the traversing carriage 20. However, in this case, the puller 47 should also have the function of a pusher, and the pusher 4 should also function as a pusher.
5 also has the function of a puller, or the loading/unloading device 27 of the transverse cart 20 is provided with the functions of the puller 47 and the pusher 45, etc. It is necessary to additionally install a device for transferring the formwork cart 17 and a device for transferring the empty formwork cart 17 from the traversing cart 20 onto the pre-curing formwork cart support 41.

This invention is not limited to the above embodiments; for example, the pusher 45, puller 47, etc.
It may be provided at the position of the uncured formwork cart support section 41 or the cured formwork cart support section 42, or may be loaded and installed on the traversing cart 20. In addition, the conveyors 11 and 12 for horizontally feeding the formwork are omitted, and a formwork sending end is provided at one end of the roller conveyor 4, a formwork receiving end is provided at the other end, and the formwork is placed above each end of the roller conveyor 4. It may be arranged in a part of the multi-tiered stacking device 50 and the formwork hanging device 58. Furthermore, the formwork multi-level stacking device 50 and the formwork hanging device 58 may have other configurations.
Further, instead of using the coupling device 34, the formwork cart 17 may be pulled out from the curing chamber 15 by a loading/unloading device that deeply enters the curing chamber 15, such as a parent-child type traverser.

In addition, the case where the formwork cart 17 is used as a formwork holder has been described above, but when a pallet is used as a formwork holder, the rails 18, 23, 46a,
A guide such as a free roller may be used instead of the guide 48a.

(Effects of the Invention) As explained above, according to the present invention, the space of the curing room is small, only one traversing cart is required, which reduces equipment costs, and enables continuous production of concrete products with high efficiency. can be installed within a small site area.
