Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete product manufacturing apparatus for manufacturing a comparatively large concrete product while vibrating a molding frame or the like with a variable vibrator.

[0002]

2. Description of the Related Art Generally, when manufacturing concrete products, in order to manufacture better concrete products, the mold should be uniformly filled with concrete, and the concrete filled in the mold should be deaerated and degassed. Need to bubble. In this way, the mold is uniformly filled with concrete, and in order to deaerate and defoam the concrete, the vibration of a vibration having a predetermined amplitude is applied to the mold and the concrete filled in the mold using a vibrator. It is necessary to give a vibration force.

Here, a plurality of, for example, two, which can change appropriate vibrations and intersecting angles corresponding to the weight of the molding die and the weight of the concrete filled in the molding die, and the like.
An appropriate vibration force due to a combined eccentric load of two eccentric weights will be described. First, let m be the synthetic mass of the eccentric weight,
The combined eccentric distance of the eccentric weight is r, the number of revolutions of the vibrator, that is, the rotating shaft is N, the angular velocity of the rotating shaft is ω (radian), the product weight is W, and the system weight of the molding form and pallet is When w, the exciting force F is

[Equation 3] Becomes

Further, the vibration acceleration n received by a system such as concrete (concrete product) or a molding form is

[Equation 4] Becomes Furthermore, the amplitude S is

[Equation 5] Becomes

From the above equations (4) and (5), in order to keep the vibration acceleration n constant, the product weight W and the system weight w
It is understood that the exciting force F may be increased or decreased according to the sum of the above, and that the rotational speed N may be increased or decreased to increase or decrease the exciting force F. Therefore, although the product weight W and the system weight w are changed due to the change of the type of concrete product, if the exciting force F is kept constant, the vibration acceleration n and the amplitude S applied to the concrete are changed, and the concrete Since the excitation force F, vibration acceleration n, and amplitude S that are suitable for the product are lost, the number of revolutions N and the eccentric weight intersect so that the excitation force F, vibration acceleration n, and amplitude S that are suitable for the concrete product are obtained. That is, it is necessary to change the variable angle.

The higher the height of the concrete product and the higher the frequency of vibration, the greater the amount of vibration attenuation. Therefore, the vibration frequency (rotation speed N) is reduced to reduce the vibration. While reducing the effect, synthetic mass m
And the combined eccentric distance r is increased to make the vibration acceleration n constant. Also, considering the type of concrete, including the state of slump of concrete (slump value), one type or multiple types of concrete, the vibration force F, vibration acceleration n and amplitude suitable for the concrete product are considered. It is necessary to change the rotation speed N and the variable angle so that S becomes S.

As described above, the variable vibrator capable of changing the exciting force F and the like changes the variable angle of the shaft rotated by the power of the motor, for example, a pair of eccentric weights attached to the rotary shaft, to change the composite mass. m and the combined eccentric distance r are changed. Then, the one in which the combined eccentric load can be changed without stopping the motor to change the exciting force F and the like, for example, the one described in Japanese Patent Publication No. 4-1826, and the motor can be stopped. It has been proposed to change the combined eccentric load to change the exciting force F and the like.

Therefore, when manufacturing each concrete product, the number of rotations at the time of manufacturing each concrete product,
The variable angle, the slump value, and the like are manually changed each time based on the vibration force table shown in FIG.
By setting the variable angle θ to an appropriate value and setting the exciting force F, the vibration acceleration n, and the amplitude S suitable for each concrete product, a better concrete product is manufactured.

[0009]

When manufacturing each concrete product, the conventional concrete product manufacturing apparatus manually rotates each concrete product on the basis of the number of revolutions, the variable angle, the slump value, etc. at the time of manufacturing each concrete product. Each concrete product is manufactured by setting the number and variable angle. Therefore, multiple concrete products
For example, in the case of cyclic manufacturing, the number of rotations and the variable angle must be manually set again each time the concrete product changes, which makes the operation troublesome.

If the rotational speed and the variable angle are set incorrectly, the concrete product will be defective. Although various variable vibrators that can change the exciting force by changing the combined eccentric load have been proposed, such variable vibrators can be used to easily operate the rotation speed and the variable angle. No concrete product manufacturing apparatus has been proposed so far, which is capable of setting a concrete product and capable of manufacturing a concrete product of uniform quality.

The present invention has been made in order to meet the above-mentioned demands, and provides a concrete product manufacturing apparatus which is easy to operate and is capable of manufacturing a concrete product of uniform quality with good yield. Is.
