DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for casting concrete products.

[0002]

2. Description of the Related Art Conventionally, in order to continuously perform cast molding of a concrete product, a free roller with a brim is mounted on both sides of a line and a movable form stand is provided. A method of transferring the formwork is adopted. In this method, a free roller with a brim protrudes from the floor on the line, which poses a danger to the operator. Also, it is not possible to provide a working floor on the chain conveyor, but in the case of manufacturing medium-sized and large-sized products, it is necessary to enter the center of the conveyor when the equipment is stopped, which is also dangerous. . Furthermore, the direction of the form stand is changed using table lifters at both ends of the conveyor for carrying in and out of the curing room. However, there is a great danger in this process.

[0003]

SUMMARY OF THE INVENTION The present invention is to provide an apparatus which has an extremely small risk even if it is an apparatus for automatically casting a large-sized concrete product. Also, when changing the direction of the formwork in order to send the product from the molding line to the curing room, a lift is not used, thereby eliminating the danger.

[0004]

According to the present invention, the steps of opening the mold, removing the mold, cleaning the mold, applying oil, assembling the mold, arranging the reinforcing bars, and casting the concrete are carried out by sequentially feeding the mold on a series of conveyors. In the molding apparatus to be performed, a rail device for transferring a formwork is provided on both sides of a vertically movable frame, a forward / backward moving cylinder is attached to the frame, and a single brim type free roller for sliding is further provided. Place the floorboard on the
The floor plate is supported in the form of a floating island by the free rollers, the form-conveying rail device is placed on wheels mounted on the holding gantry to be movable, and the rail device is moved up and down via the holding gantry and the wheels. A cast concrete product forming apparatus characterized in that a cylinder is provided at an appropriate position below a holding frame.

This molding apparatus is provided integrally with a curing room, and a turntable having the same floor is provided before and after the molding apparatus to form a passage for carrying a mold into and out of the curing room.

According to the present invention, after each mold has completed the expected process, the rail device is lifted to project the rail device from the floor surface, and is advanced one frame by the forward / backward moving cylinder to proceed to the next process. Next, the rail device is lowered to the floor surface, and the forward / backward moving cylinder is moved backward to prepare for the next formwork advance. When the rail device is moved, the floor plate is supported by the slide single-branch free rollers, so it is supported in a floating island shape, and the floor plate does not move even if the rail device moves. Therefore, a hole is not formed on the floor surface where a worker falls carelessly, and the stability is high. In addition, since the transfer of the formwork to and from the curing room is performed by a turntable at the same floor level as the molding line, there is no danger here and the handling is easy.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a conceptual plan view of a concrete product forming apparatus to which the present invention is applied. A to J indicate molds at each molding stage. For example, A and B indicate a mold opening process,
C and D indicate a demolding process, E indicates a mold cleaning process, F indicates a mold oiling process, G indicates a mold assembly process, H indicates a reinforcing bar reinforcing process, I indicates a concrete pouring process, and J indicates a finishing process. Each process is shifted by a forward / backward moving cylinder 12 provided at various places. The finished concrete product is transferred to the turntable L while being stored in the formwork 1 where it is 90 °
The traverser 3 changes the direction and moves on the carry-in path 2, and is sequentially carried into each spot of the curing room 4 by the traverser 3. The cured product is taken out by the traverser 3 while remaining in the formwork 1 and reaches the turntable K via the unloading path 5. Turn A to turn 90 ° and turn to A
Steps J to J are repeated. The mold bases 1, 1,... Move from the turntable K to the turntable L through each of the molding steps A to J. However, if the transfer means is exposed on the floor, an accident may occur. Become. In particular, the formwork base 1 has recently become larger, and it is necessary to enter the line for repairs and the like more often, and the chances of accidents are increasing.

FIG. 1 shows a main part of the present invention.
It is I sectional drawing. In the drawing, reference numeral 1 denotes a mold frame which is moved on a molding line, and the movement is performed by the following mechanism.
Reference numeral 6 denotes an elevating cylinder, which is provided everywhere on the moving line. Although the right side is shown in a cross section different from the left side for convenience, a guide shaft 7 is provided between the lifting cylinders 6 to stably guide the lifting and lowering by the lifting cylinder 6. Reference numeral 8 denotes a holding base that is raised and lowered by the lifting cylinder 6, and wheels 9 and 9 are rotatably mounted on both sides. 10
Is a rail device attached to both ends of the frame 11. A forward / backward moving cylinder 12 is attached to the frame 11, and controls the forward movement of the form stand 1 and the backward movement for returning to the previous process. The frame 11 is provided with a sliding single-branch free roller 13 near both sides, and the free roller 13 supports the floor plate 14 by mounting its legs 15 thereon. This floor plate 14 is just a free roller 1
The support is a so-called floating island just by being placed on 3.

The operation of the apparatus will be described.
In FIG. 1, after a predetermined process operation is performed, and after the operation is completed, since the case of FIG. 1 corresponds to the II section of FIG. 2, the mold base 1 is transferred to the turntable L. First, when the holding cradle 8 is raised by operating the lifting cylinder 6, the wheels 9
At the same time, the rail device 10 resting on the wheels 9
, So that the upper end of the rail device 10 reaches the lower surface of the formwork base 1 and further lifts it. Next, when the frame 11 is moved forward by operating the forward / backward moving cylinder 12, the rail device 10 moves on the wheels 9. During this movement, the floorboard 1
4 is mounted on the free roller 13 by its legs 15 and held in a floating island shape, so that the rail device 10 and the
Following the movement of, stop at the original position. The form base 1 moved to the turntable L is placed on the form carriage 17 on the rail 16 of the turntable L, is turned 90 °, passes through the loading path 2, and is carried to the curing room 4. It is stored in a predetermined curing room by the traverser 3. The cured product is carried out of the curing room 4, passes through the right carry-out path in FIG. 2, reaches the turntable K, changes its direction by 90 °, and enters the process A position again. Hereinafter, predetermined steps are repeated.

[0011]

The concrete molding apparatus according to the present invention is a system in which the movement of the form base is simultaneously moved for each process, and the rail device is sequentially sent in an ascending, advancing, descending and retreating order. Therefore, the working floor is kept the same as the floor surface in the apparatus, so that the transfer device and the like are not exposed, there is no gap where the workers fall, and the working floor does not protrude from the working floor. Therefore, the worker does not have a sense of anxiety such as stumbling, dropping, etc., and can perform work with a sense of security, thereby improving work efficiency.
