Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to cement and aggregate (sand,
The present invention relates to an apparatus for producing an empty-kneaded concrete (hereinafter referred to as an empty-kneaded concrete) in which gravel or the like is mixed and water is not added.

[0002]

2. Description of the Related Art Concrete in Japan, so-called ready-mixed concrete (JIS ready-mixed concrete),
It is made by adding cement, aggregate (sand, gravel, etc.) and water and kneading. It is produced in a concrete plant, transported to the site by a special agitator car, and cast. For this reason, it is used in large quantities for large-scale building construction and the like, or for parts requiring strength. However, a concrete plant is usually operated only in the daytime. For example, when the ready-mixed concrete is required at night, it is necessary to knead cement, aggregate, and water to produce the ready-mixed concrete on site. In addition, for example, when 0.2 m ³ of ready-mixed concrete is required, a normal concrete plant often only adheres to the mixer and cannot be kneaded because the kneading amount is too small. Concrete must be kneaded. They are,
In any case, ready-mixed concrete cannot be built and placed,
The casting must be done within 2 hours after production, and the concrete plant is a facility for mass production.
This is because the structure is not suitable for small-volume production.

[0003] On the other hand, dry-mixed concrete is a mixture of cement and aggregate, and since it is not added with water, it can be transported by ordinary trucks or the like. Also, depending on the water content of the aggregate, it can be stored for several days, and when ready-mixed concrete is needed, it can be used by adding only water, so that its convenience has been recognized. However, JIS standard concrete is only the above-mentioned ready-mixed concrete, and empty-mixed concrete is not standardized. In addition, the purpose of the concrete plant is to produce ready-mixed concrete. Since it requires extra work such as cleaning and drying, it takes time and the operation is poor, so it is not handled and is difficult to obtain in concrete plants.

[0004]

SUMMARY OF THE INVENTION According to the present invention, the convenience of empty kneaded concrete can be fully utilized by adding the above-mentioned point that the empty kneaded concrete does not add water and the means corresponding to unmanned operation. It is an object of the present invention to provide a manufacturing apparatus capable of obtaining empty concrete.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a measuring device for measuring the weight of cement and aggregate (sand, gravel, etc.) as materials, and a mixer for mixing the measured materials. An apparatus for manufacturing a ready-mixed concrete comprising a storage unit for storing a mixing ratio and an input unit for selecting a mix and setting a mixing amount, wherein a settlement process for managing the manufacture and sale of the ready-mixed concrete Means.

[0006]

FIG. 1 is a block diagram showing an apparatus for producing a compacted concrete according to the present invention. First, the outline will be described. As in the ready-mixed concrete plant, the apparatus for producing a ready-mixed concrete according to the present embodiment includes a weighing device 1 above a mixer 2 and further carries a material above a weighing device by a belt conveyor. The ready-mixed concrete can be obtained by measuring the required amounts of cement, sand, and gravel, which are materials, by a measuring device 1, charging the measured materials into a mixer, and kneading with a mixer 2. The measuring device 1 and the mixer 2 may have the same structure as the device used for the production of ready-mixed concrete. However, empty-mixed concrete is in a subordinate state to the master of ready-mixed concrete, and it is difficult to imagine a large demand at one time. Therefore, the mixing capacity of the mixer is 1.0 m ³ . The mixing instructing means 4 having the support portion 3 for instructing these devices to perform measurement, mixing, and the like, includes a storage portion 5 for storing several kinds of mixing ratios of the empty concrete to be mixed in advance, and a mixing and mixing amount required by the customer. The input unit 6 is provided for inputting the input of the input unit 6. The input unit 6 is used to select the mixing ratio of the storage unit 5 and set the mixing amount in accordance with the signal from the input unit 6, or to directly input the mixing ratio arbitrarily from the input unit 6. . After the completion of the measurement, the measured value of the material by the measuring device 1 can be output from the output unit 7 provided in the mixing instruction means 4. Further, it is possible to output a receipt in which necessary items of the settlement processing means 8 are entered based on the data from the mixing processing means 4.

[0007] Next, the procedure for producing the empty concrete will be described in detail. The user of the empty concrete mixes the name of the user, the mixing amount, and the combination from the input section 6 of the mixing instruction means 4. At this time, the customer name is input by passing a registration card, which is registered and supplied in advance, through a card reader. The mixing amount is equally divided into five stages from a minimum of 0.2 m ³ to a maximum of 1.0 m ³ , and is selected from a touch panel type screen. The mixing ratio is stored in the personal computer which is the storage unit 5, and is determined to be 15N, 16N, 18N depending on the concrete strength.
・ Five types of 21N (when adjusted to slump 18) and one type of one-to-three mortar are prepared. A necessary composition is input from the composition on the same screen of the touch panel system in accordance with the above-mentioned mixing amount. As a matter of course, an arbitrary mixing ratio may be directly input from the input section.

In accordance with these inputs, the indicating unit 3 operates the measuring device 1
, The measured value is indicated, and the measured material is put into the mixer 2 and mixed. At this time, the actual measurement value actually measured for the weight of the material instructed to be weighed is fed back from the weighing device 1 to the instruction unit 3 and output from the output unit 7. Note that the instruction unit 3 is constituted by a sequencer.

When the mixing of the mixer 2 is completed, the data input from the input unit 6 is sent from the instruction unit 3 to the settlement processing means 8, and the production date / time / mixing ratio /
A receipt with the mixing amount and the name of the customer is output.
Further, the data sent to the settlement processing means 8 includes
The billing amount is calculated based on the mixed amount and is collected for each customer at the end of each month, so that billing can be easily performed.

In this embodiment, the input to the input unit is
Although the example using the card reader or the touch panel method has been described, a keyboard input is also possible. Further, a personal computer may be used instead of the sequencer used for the instruction unit.

[0011]

According to the first aspect of the present invention, since the mixing processing means and the settlement processing means are provided, it is possible to manufacture and sell the empty kneaded concrete regardless of day and night, and to meet the urgent demand. Can respond. According to the second aspect, since the mixing unit is provided with the output unit that outputs the actual measurement value, the actual mixing ratio can be confirmed, and the strength can be confirmed. According to the third aspect, since the input unit is provided with the card reader, if the user does not have a registration card, the manufacturing apparatus cannot be operated, and the customer who is used is identified. Helps to prevent
