Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to a concrete charging table used for pouring concrete into a formwork for forming concrete blocks, and is particularly effective for automating the production of concrete blocks. It is.

<Prior art> Concrete blocks are formed by pouring concrete into molds. Concrete is poured into the formwork using a screw conveyor, etc. In this case, it is necessary to add an appropriate amount of concrete, but conventionally this amount has been manually checked by a worker visually. If there is a lot of concrete, it is necessary to remove the concrete that has risen on top of the formwork, and if there is a small amount, it is necessary to replenish the concrete.

The top surface of the formwork is leveled using a core. In addition, a table vibrator is used to ensure that the concrete is spread throughout the formwork at the time of injection.

<Problems to be solved by the invention> Since the above-mentioned work is required to pour concrete into the formwork, it must be done manually by workers at the factory, so it is necessary to mechanize and automate the work. It is difficult to do so, and mass production is not possible because it requires relying on human labor.

In other words, in order to automatically manufacture concrete blocks using mechanical power, the first step is to automate the process of putting concrete into formwork.

Means for Solving the Problems> Therefore, in the concrete charging table according to the present invention, a table having a charging port formed above the table vibrator can be moved up and down with respect to the table vibrator and can be fixed at any position. At the same time, a leveling core that reciprocates on the table is arranged, and the pouring formwork is placed on the table vibrator so that the inlet of the pouring form coincides with the inlet of the table, and the table vibrator and the table are connected to each other. Fix the formwork by sandwiching it in place, put the concrete into the formwork while operating the vibrator, level the concrete that has risen on the table, move the core back and forth on the table, scrape it off and level it, and remove the concrete from the formwork. This system is designed to automate everything from the placement of concrete to the pouring of concrete into the formwork and leveling of the formwork.

Embodiment Next, an embodiment of the concrete charging table according to the present invention will be described based on FIGS. 1 to 3. 1 is a table vibrator on which a vibrator 2 is disposed;
The part placed on the formwork is a belt conveyor 3, and is installed on a base 5 via seismic rubber 4. Reference numeral 6 denotes a table on which a charging lower is formed, and is connected to the table vibrator 1 by a hydraulic cylinder 8.

The table 6 is constructed in a box shape with an upper plate 9 and a lower plate 10, and a guide plate 11 is arranged in parallel in a space inside the table 6 with the input lower sandwiched therebetween. Reference numeral 12 denotes a leveling core connected to a hydraulic cylinder 13, and is adapted to reciprocate above the input lower along the guide plate 11. 14 is a hopper for charging concrete, and 15 is a screw conveyor. 16 is a discharge chute for discharging excess concrete on the table 6 through the leveling core 12.

Further, the table 6 may be formed by folding a single flat plate as shown in FIG. As shown in FIG. 5, a regulating plate 17 may be disposed on the lower surface of the table 6 so as to sandwich the input lower, or may be disposed on three sides or on the entire circumference.

Function> The hydraulic cylinder 8 is expanded to widen the space between the table vibrator 1 and the table 6, and the belt conveyor 3
is operated to set the formwork K in a position that coincides with the charging lower of the table 6. Next, the hydraulic cylinder 8 is retracted and the formwork K is fixed on the table 6. At this time, if a regulating plate 17 as shown in FIG. 5 is provided, the formwork 17 is automatically set in the correct position by lowering the table 6. Then, the screw conveyor 15 is operated to charge the concrete in the hopper 14 into the formwork.

At this time, depending on the capacity of the formwork, the screw conveyor 1
By setting the operating time in step 5, concrete can be poured automatically. In this case, the amount of poured concrete is set so that a small amount of concrete rises on the table 6. For example, if the capacity of the formwork is 18 or more, the input amount should be about 18.1 or 18.2 fL. Further, when carrying out this charging operation, the vibrator 2 is operated to give vibration to the formwork K so that the concrete is well spread to every corner of the formwork. Since the table vibrator 1 and the table 6 are sandwiched and fixed to the formwork, its position will not move even if vibration is applied. Next, when the prescribed amount of concrete has been poured and the concrete has been spread to every corner of the formwork, the hydraulic cylinder 13 is activated to reciprocate the leveling core 12 and remove excess concrete on the table 6. is discharged from the discharge chute 16. Then, the leveling core 1z is reciprocated several times to discharge excess concrete and level the concrete surface of the formwork. Then, the hydraulic cylinder 8 is extended to raise the table 6, release the fixation to the formwork, operate the belt conveyor 3, and move the formwork K.
Move to the next process.

The operating time and timing of the screw conveyor 15, the operating timing of the hydraulic cylinder 8, the operating timing of the vibrator 2,
If the operating timing and operating time of the hydraulic cylinder 13 and the operating timing of the belt conveyor 3 are set in advance, these operations can be performed automatically.

<Effects of the Invention> As described above, according to the concrete charging table according to the present invention, the position of the formwork is regulated and fixed using the table vibrator and the table, so that the setting of the formwork is automatically performed. Moreover, since a reciprocating leveling core is disposed on the table, processing after concrete is poured can be performed automatically, and the concrete pouring work can be completely automated.
