Description

Brick molding method and apparatus {Brick molding method and it's molding machine}

The present invention relates to a brick forming method and apparatus, and more particularly, to provide a sufficient strength by varying the method of supplying materials for forming bricks, as well as a brick forming method for producing a brick of excellent quality and Relates to the provision of a device.

Brick forming apparatus is composed of a molding machine for forming a brick (block) of the desired shape and a brick forming system consisting of a plurality of transfer lines and curing lines, discharge and masonry line.

In the brick forming system, a molding machine receives a mortar mixed with an appropriate amount of cement, sand, and water, and supplies a predetermined amount on the mold to complete molding by vibration and compression.

Conventionally, such a brick forming system and a molding machine associated with the same have been developed and used, and a representative molding machine thereof is shown in FIG. 1.

Looking at it;

The molding machine 1 is supported by a frame 4 with a storage tank 3 which receives mortar mixed with cement, sand and water by the conveyor 2.

Below the reservoir 3 is provided a feed tank 7 for supplying mortar to the mold 6 provided with the vibrator 5 in front of the frame 4, above the mold 6. A press 8 for pressing the mortar supplied into the mold 6 to form a brick (block) is provided.

Below the molding machine 1 is a configuration in which a pallet for laying the bricks to be molded and a transfer line 9 for transferring the bricks formed on the pallet to the curing line are located.

The feed tank (7) has an impeller (11) rotated by the motor (10) so that the supplied mortar can be evenly introduced into the mold (6), the press (8) is connected to the frame (4) , The cylinder 12 and the pressing plate 13 to operate by pneumatic, etc., the operation of the molding machine 1 is a configuration that is controlled by a controller 15 provided separately.

The conventional molding machine 1 is configured as described above;

By operating the controller, the pallet supplied through the transfer line is located under the mold, the press is in an elevated state, and the conveyor supplies mortar to the storage tank.

When the mortar is filled into the supply tank by the supply of mortar, the supply tank moves in the mold direction to supply the mortar. In the process of supplying the mortar into the mold, the impeller installed in the supply tank rotates so that the mortar is evenly inserted into the mold.

The supply tank, which has finished supplying mortar, retracts and at the same time the mold vibrates by the vibrator and the press descends to press the mortar in the mold to form a brick.

After the molding of the brick is completed, the press is further extended to lower the molded brick and supply it to the transfer line, and then return to the initial state.

The brick is formed by repetition of the above operation. In the related art, the mortar is not smoothly supplied to any one of the upper surfaces of the mold because the mold is finished by supplying the mortar once.

In this state, the brick is formed by pressing together with the vibration, and thus the finished brick is treated as a defect, and the brick in a position where the mortar supply is not smooth is often molded into a substandard brick in strength and density.

In particular, when the same pressure is applied by the press because it is molded in a state that the mortar supply is not smooth, it is due to the difference between the normal supply and the other;

Since the mold vibrates in a state in which a large amount of mortar is concentrated at a time, the mortar is formed without being sufficiently compacted in the mold, thereby providing a cause such as uneven density of the molded brick.

In order to solve this problem, in order to increase the viscosity by increasing the moisture content of mortar or increase the supply time of mortar, various industrial standards, such as failure due to breakage due to expansion of bricks, are also failed. There were problems.

Accordingly, the present invention is to solve the problems as described above to improve the molding machine and to improve the supply method of mortar to uniform the density of the brick to be formed to obtain sufficient strength to produce a good quality brick and block It aims to be able to contribute to.

2 is a schematic front view of a brick forming apparatus to which the technique of the present invention is applied, and FIG. 3 is a schematic cross-sectional view of a brick forming apparatus to which the technique of the present invention is applied.

The molding machine 50 is applied to the brick forming system consisting of a transfer line, a curing line, a discharge and a masonry line to form a brick (block);

A storage tank 3 supported by the frame 51 and supplied with mortar by the belt conveyor 52 is provided, and a mold 55 having the vibrator 54 integrally provided at a lower front side of the storage tank 53. do.

Below the reservoir 53 is provided a supply tank 58 having an impeller 57 rotating therein by a motor 56 as a means for supplying mortar to the mold 55.

Above the mold 55, a press 61 having a cylinder 59 and a pressing plate 60 is provided as a means for pressing the mortar supplied into the mold 55 to form bricks. Operation of the configuration is controlled by the controller 70 is provided separately.

In the present invention, the supply tank 58 has a mold 55 so as to further have a logic circuit for supplying the supply tank 58 in the mold 55 direction to the storage tank 53 and the controller 70 of the molding machine. The mortar supply of the furnace is divided into two times so that high density and high strength bricks can be formed.

If you look at it,

The controller 70 is further improved so as to further have a logic circuit for supplying the supply tank 58 for supplying the mortar from the storage tank 53 to the mold 55 twice, thereby supplying the supply tank 58 to the mold 55. Control the drive means such as motor or cylinder to move forward and backward in the direction of).

By supplying the supply tank 58 twice in the direction of the mold 55, an inclined partition wall is formed inside the storage tank 53 so as to appropriately adjust the amount of mortar supplied from the storage tank 53 to the supply tank 58. 80) install.

An auxiliary impeller 81 is further installed between the partition wall 80 and the outer wall (left side of the drawing) of the storage tank 53 so that mortar can be smoothly supplied to the supply tank 58.

The auxiliary impeller 81 may be driven by a separate motor that operates in conjunction with a sensor that detects a supply state of mortar or may be operated in conjunction with another driving source of the molding machine 50.

Looking at the operation of the present invention as described above, the mortar is supplied to the storage tank 53 by the belt conveyor 52, the mortar in the storage tank 53 is filled into the supply tank 58 of the lower.

When the mortar is filled in the supply tank 58, the supply tank 58 moves in the direction of the mold 55 to supply the mortar on the malt 55, and then retreats. The mortar in the mold 55 is transferred to the mold 55. The operation of repeating one cycle in which brick forming is completed by vibratingly compacted by the vibrator 54 and simultaneously pressing the upper press 61 downward and compression molding is the same as in the prior art.

In the present invention, the supply tank 58, which is supplied with mortar from the storage tank 53 by the logic circuit of the controller 70 so that the supply tank 58 can be supplied twice in the mold 55 direction, molds mortar at once. The small density of the mortar in the mold 55 is improved by supplying a small amount twice in two times without supplying a large amount to the 55 so that a high density high strength brick is formed.

In particular, since the appropriate amount is supplied to the inside of the storage tank 53 by the bulkhead 80 and the auxiliary impeller 81 which are installed to prevent a large amount of mortar from being supplied to the supply tank 58 at once, the supply tank 58 is provided. There is no problem caused by excess mortar even if the mold 55 is repeatedly moved back and forth over the second time.

As described above, even if the supply tank 58 is supplied twice in the mold 55 direction, the cycle of the entire molding machine 50 is not delayed, which is about 3 to 4 after the conventional supply tank enters the mold. In the present invention, 0.5 to 0.7 seconds is required for one-time supply and the overall time is rather shortened because it waits for one second after the retreat.

The present invention as described above;

Since the mortar required for brick forming is divided into two times, the mortar with high moisture content is used to obtain high strength and high density brick.

In addition, since the mortar is supplied to the mold twice, the mortar is evenly supplied throughout the malt, and even if the aggregate quality is a little poor, sufficient compacting effect can be obtained, so that the specification, strength, and water absorption rate exceed the industrial standards. It has the advantage of producing

The present invention as described above has the effect that it can contribute to the production of bricks and blocks of good quality by improving the molding machine and improving the mortar supply method to make the density of the brick to be uniform to obtain sufficient strength. .
