Description

Detailed Description of the Invention The present invention loads ready-mixed concrete that has been formed into forms into multi-stage moving racks, cures each rank, and circulates the concrete while producing a variety of completely solidified concrete products and demolding the concrete. This device transports the finished product to a stockyard, automatically transfers the formwork as it is to the formwork return line, and automatically performs cleaning of the formwork, spraying of release agent, and assembly of the formwork.

With conventional poured concrete blocks, after filling the formwork with ready-mixed concrete, the labor of compacting the fresh concrete filled in the formwork, transporting it to the curing room, and removing the formwork is mostly done manually. This required a large number of workers and a large amount of formwork, making it unsuitable for mass production.

This invention was developed in view of the above-mentioned circumstances, and it continuously automates most of the processes from pouring fresh concrete into formwork, curing and fully setting concrete products, to demolding to mold setting, thereby reducing labor costs. Medium savings, speeding up the production process,
As a result, production costs are significantly lowered, making it suitable for mass production.

Next, one embodiment of the present invention will be described with reference to the drawings. Fresh concrete mixed with cement, sand, gravel, and water is fed into the mobile kerato (■) using the mixer (2), then fed into the feeding machine (2), and then placed on the molding table. ■It is put into the upper formwork■, where it is compacted by vibration and the density is made uniform, and then it is sent to the chain conveyor■ by a special transfer device■. Load it onto the formwork loading machine ■t trowel and multi-stage moving rack ■. After passing through the outgoing line by automatic rack transfer equipment M@,
A special automatic rack transfer device ■ sends it to the curing room [phase], where it becomes a fully solidified concrete product, and once it leaves the curing room, it is continuously returned to the outgoing line by a special automatic rack transfer device @. Multi-stage mobile rack circulation curing system.

The solidified concrete products and formwork loaded on the multi-stage mobile rack are lowered onto the chain conveyor @ by the formwork unloader, and sent to the formwork return line where they are transferred to the formwork automatic transfer device [phase]. The concrete product is then sent to the form opening machine @, where the form is opened and then sent to the demolding device [phase].The concrete product is unloaded onto the stock conveyor◎, the form is automatically transferred as it is, and the form is vacuumed. It is cleaned with [phase], and the release agent is sprayed by a machine @ number. The mold is automatically transferred, and the formwork is assembled by the formwork assembling machine [phase], which is automatically transferred, and then lowered to the chain conveyor ■ of the molding line by the formwork transfer device [phase], and then transferred to the roller conveyor [phase] by the chain conveyor. The products are stocked at the special transfer device (■) and sent to the molding table (■) and the chain conveyor (■).

The above steps are automatically repeated.

In short, this invention has automated and continuous the entire process from curing after loading the ready-mixed concrete to demolding and assembling the formwork, whereas conventionally the operation was done manually except for adding the ready-mixed concrete into the formwork. It is something. Therefore, it is possible to exhibit technical and economical effects that significantly improve work efficiency and save labor.

Claims (1)

[Claims] tl+ Ready-mixed concrete placed in a formwork is automatically transferred and loaded onto a multi-stage moving rack by a formwork loading machine. The moving rack is transferred to the outbound line by an automatic rack transfer device.
A special automatic rack transfer device moves it to the return line. This line is a curing room, where the product is cured while being transported to a completely solidified concrete product. Once it exits the return line, it is continuously returned to the outbound line using a special automatic rack transfer device. A multi-stage moving rack circulation curing system. (2) The solidified concrete products and formwork loaded on the multi-stage mobile rack are unloaded from the rack by a formwork unloading machine, placed on the formwork return line, and then automatically transferred to open the formwork. After passing through the machine, only the product is taken out from the line by a demolding device, transported to the stockyard, and the formwork is automatically transferred to the formwork return line, where the formwork is cleaned, sprayed with release agent, etc., and the mold is removed. After passing through the frame assembly machine, the fresh concrete is placed on the molding line again, and while being automatically transferred, the fresh concrete is introduced into the formwork using a shaking table and loading machine, and then continuously loaded onto a multi-stage mobile rack. This is a formwork circulation system that uses a combination of
