Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a ready-mixed concrete batch plant,
In other words, the aim is to modernize the management and improve the structure of ready-mixed concrete factories equipped with ready-mixed concrete production equipment, and in particular, to compare the number of measurements of cement weighing scales in ready-mixed concrete production equipment with the shipping output data reported to cooperatives. This relates to a shipping management method that allows managers to clarify cause-and-effect relationships at a later date.

[Conventional technology]

In general, a ready-mixed concrete batch plant, i.e., a ready-mixed concrete factory equipped with ready-mixed concrete manufacturing equipment, handles tasks such as measuring and mixing various materials, loading ready-mixed concrete into ready-mixed concrete trucks, etc. in response to orders from distributors or construction sites. working on it. By the way, the shipping management at this ready-mixed concrete factory is as follows.
The work is complicated because the mixing ratio and shipping amount of concrete are different for each construction site, and the shipping amount often changes depending on the weather at the construction site and the progress of the work. For this reason, in the past, shipping personnel have been in contact with each construction site over the phone and manually decided on process changes and managed shipping. It was also bad. Although these are the key points in the business management of a ready-mixed concrete factory, these constitutional shortcomings still persist. In addition, in recent years, cooperatives have been formed and operated on a cooperative basis to improve the quality of ready-mixed concrete and stabilize prices, with the aim of jointly ordering and selling concrete. When orders and sales are made on a cooperative basis in this way, each ready-mixed concrete factory must accurately report the quantities produced and sold to the cooperative.

Conventionally, shipping management for each cooperative's ready-mixed concrete factory was automatically carried out based on the shipping schedule determined by the cooperative, and errors in the shipping output data sent from the ready-mixed concrete factory to the cooperative were avoided. No device had been developed to eliminate the omission of reports due to such reasons.

In addition, conventionally, in ready-mixed concrete factories,
Like the idea described in Publication No. 49-37946, a system is used that gives commands such as the mix of ready-mixed concrete, the load per vehicle, and the number of continuous shipments to the ready-mixed concrete production equipment while checking it with a display. ing. However, this device is nothing more than a shipping command device that sends the data input in order by operating the switches and buttons to the ready-mixed concrete production equipment in the order in which they are input.

[Purpose of the Invention] The present invention efficiently handles complex shipping management at a ready-mixed concrete factory using a device incorporating a microcomputer, and also allows operator operations to be applied to shipping output data reported to a cooperative. To automatically record the number of measurements of a cement weighing scale in a ready-mixed concrete factory, which is accurately detected without being changed by mistake or manipulation.

[Structure of the invention]

The first invention of the present invention is to provide a microcomputer 1 comprising a CPU 2, ROM 3, and RAM 4 to a ready-mixed concrete factory, and data such as customer name, mix number, shipping amount, arrival time, etc. written on a shipping schedule tape 106. A series of data corresponding to one construction site is read from the file memory by inputting a key code and a tape reader 15 that reads the shipping schedule plan by scheduled shipping date to be stored in the film memory in the RAM. , modify the shipping schedule such as changing the shipping amount, and then enter the above key code to send data 1 command corresponding to the control device of the ready-mixed concrete manufacturing equipment according to the above shipping schedule. A shipping management device 1 consisting of an operation console 5 for printing, a printer 9 for issuing delivery notes, daily shipping reports, etc.
05, and a control device 11 for the ready-mixed concrete manufacturing equipment that controls operations such as measuring and kneading various materials, and the control device 1 for the ready-mixed concrete manufacturing equipment is installed.
1 is provided with an outlet for a cement measurement start signal and an outlet for a cement discharge signal, and the condition is that a valid cement measurement start signal and a cement discharge signal that led to the cement to flow out occur in this order. The number of times of weighing by the cement weighing scale is detected by the logical product, and the number of times of weighing and the number of continuous accumulations for one shipment are calculated at each shipment. The shipping output data, which is added to the end of the output data and further includes the number of measurements for one shipment and the number of continuous accumulations, is recorded on a recording medium such as a delivery tape using a recording device such as a tape puncher. A second invention of the present invention is a shipping control method for improving ready-mixed concrete. The day before ready-mixed concrete is shipped, a terminal is added that receives shipping schedule data based on the shipping quota of each factory and association management information, and transmits shipping output data to the computer center, and the above delivery tape etc. By sending the data recorded on a recording medium to the computer center via the terminal at the ready-mixed concrete factory, the printer at the ready-mixed concrete cooperative's terminal will print out a factory shipment management table with the above-mentioned shipping output data printed out. This is a shipping management method for improving ready-mixed concrete, which makes it possible to easily establish a causal relationship between the number of times of measurement using a cement weighing scale and the shipping output data.

0 is a weighing hopper of a weighing scale installed at the bottom of each of the above-mentioned hoppers. 21' to 30' are the gates of the respective hoppers mentioned above. 31 to 35 are chute, 36 is a mixer, and 37 is a ready-mixed concrete truck.

The outlet 18a for the cement measurement start signal f and the outlet 18b for the cement discharge signal g are included in the control device 11 of the ready-mixed concrete production equipment, and the signals f and g from the control device 11 control the cement storage hopper. The gate 21' of the weighing hopper 21 and the gate 26' of the weighing hopper 26 are controlled respectively. In addition,
The gates 21' to 25' are closed by a measurement completion signal when the weighing scale weighs a set amount. The outflow status of cement from the gate 21' of the cement storage hopper 21 is monitored, for example, visually by an operator or by a computer. Therefore, if cement is clogged and does not flow out, The operator manually outputs the cement measurement start signal g several times and opens and closes the gate several times until the cement flows out. If the cement does not flow out even when the gate is opened and closed manually, the operator will hit the gate with a hammer to clear the cement blockage at the gate, and then output the cement measurement start signal g again. .

Even if the gate 26' of the weighing hopper 26 of the weighing scale becomes clogged, the cement blockage is cleared by the same operation as described above. After discharging the cement, the gate 26' of the weighing hopper 26 may be closed by the zero weighing signal of the weighing scale, or may be closed by the next cement weighing start signal g.

In short, the cement measurement start signal f, and
The cement discharge signal g is not necessarily output only once. Therefore, the effective cement measurement start signal f that led to the cement flowing out, and
On the condition that the cement discharge signals g are output in this order, this is counted as one measuring operation as a logical product. In addition, the gates 22' to 25' of the other storage hoppers 22 to 25 are simultaneously controlled by the cement measurement start signal f, and the gates 2 of the weighing hoppers 27 to 30 are controlled by the cement discharge signal g.
7' to 30' are also controlled at the same time.

As shown in FIG. 2, the cooperative D of the ready-mixed concrete factory is equipped with a terminal device 120 connected to the computer center 101.
20, as shown in FIG. 4, an operation console 120a consisting of various keyboards and a paper tape reader 120;
b, a paper tape punch 120c, and a printer 120d.

In the operation of the cooperative D of the ready-mixed concrete factory with the above configuration, orders for ready-mixed concrete from each construction company are received by the ready-mixed concrete cooperative in bulk, and the orders are entered into the cooperative's terminal 120, and the orders are sent to the operator's console shown in FIG. 120a, the order data is input to the computer center 101, and the computer center 1
01 memory file (not shown).
The day before shipment of ready-mixed concrete, the cooperative makes shipment allocations for each factory, and sends data from the computer center 101 to the terminals 104 of each factory, that is, ready-mixed concrete factories A, B, and C. A shipping schedule table 107 and a shipping schedule tape 106 are printed out.

On the other hand, in order to manage shipping of ready-mixed concrete plants, that is, plants A, B, and C using a device having the above-mentioned circuit configuration, first, the shipping schedule tape 106 is prepared by a computer service network using a communication line. is set in the tape reader 15 of the shipping control device 105 of the ready-mixed concrete factory, and the shipping plan for the day is stored in the file memory in the RAM 4 of the microcomputer 1. Furthermore, at this time,
A key code is set at the beginning of a series of data corresponding to one construction site among various data stored in RAM 4, such as customer name, compounding number, shipping amount, arrival time, etc., and that key code is shipped. Management device 1
All the necessary data regarding ready-mixed concrete to be delivered to one construction site can be output by simply inputting it into the microcomputer 1 from the operation console 5 of 05. The above key code is assigned to the ready-mixed concrete cooperative D, and sent from the computer center 101 to the ready-mixed concrete factory, that is, A, B,
Shipping schedule 107 by terminal 104 of factory C
When typing the key code, the series of data called up by the key code is printed in an easy-to-understand manner at the beginning. When the ready-mixed concrete truck for transporting ready-mixed concrete to each construction site arrives at the ready-mixed concrete factory, the operator of the ready-mixed concrete factory looks at the shipping schedule 107 mentioned earlier and enters the key code corresponding to each construction site from the operation console 5. The data is input to the microcomputer 1. Then microcomputer 1
From there, a series of data corresponding to the key code is sent via the interface 12 to the control device 11 of the ready-mixed concrete manufacturing equipment, and after measuring and kneading various materials based on this data, the ready-mixed concrete is Load into ready-mixed concrete truck. In addition, when measuring and kneading the various materials, the microcomputer 1 controls the control device 11 of the ready-mixed concrete manufacturing equipment, as shown in the flowchart of FIG.
Cement measurement start signal output port 18a included in
The number of measurements of the cement weighing scale is detected by the logical product of the effective cement measurement start signal f and the cement discharge signal g, which caused the cement obtained to flow out from the cement discharge signal outlet 18b, respectively. Calculate the number of weighing times for one shipment and the number of continuous accumulations. The reason why the number of measurements of the cement weighing scale is detected by the logical product of the effective cement measurement start signal f and the cement discharge signal g is that the cement storage hopper 2 is opened by the cement measurement start signal f.
The gate 21' of No. 1 and the gate 26' of the weighing scale 26, which are opened in response to the cement discharge signal g, always discharge cement when opened by a single signal due to a clogging phenomenon near the cement discharge port. However, each signal may be output several times during one measurement, and if the number of measurements is detected only by one signal, for example, the cement measurement start signal f, it will be extremely inaccurate. This is because the data will become boring. In other words, as in the device of the present invention, the logical product, that is, the fact that the effective cement measurement start signal f that caused the cement to flow out and the cement discharge signal g that is output thereafter are generated together in this order is one. The above problem can be solved by detecting the measurement of times. Furthermore, in the present invention, one shipment of ready-mixed concrete is detected by one measuring operation of the cement weighing scale, which means that even though ready-mixed concrete without gravel etc. may be produced, ready-mixed concrete without cement is produced. It focuses on the fact that this will never happen. If a key code is set for each set of data corresponding to each construction site in this way, when a ready-mixed concrete truck arrives, the operator at the ready-mixed concrete factory can input the key code corresponding to the construction site to which the ready-mixed concrete truck is being transported. is shipping control device 1
All the data necessary for the construction site can be called up by simply inputting it into the microcomputer 1 of the 05. Also, when the shipping amount changes due to the weather or the progress of work at each construction site, the key code corresponding to that construction site is input into the microcomputer 1 to call up various data regarding that construction site, and then the It is only necessary to change only the necessary portions of the data by operating the console 5. When shipping to each construction site is completed, a delivery note a, a daily shipping report, etc. may be produced by the printer 9 as necessary.

In addition, once the shipment to each construction site is completed, the shipping output data with the number of measurements for one shipment and the number of continuous accumulations added as described above is sent to the ready-mixed concrete factory's shipping management, as shown in the flowchart in Figure 5. A recording device such as a tape puncher of the device 105 is used to punch out the tape e to be delivered to the cooperative. Then, the delivery tape e is inputted from the tape reader 104b of the terminal 104 at each factory, and
If the data is transmitted to the computer center 101 via the
From there, daily shipping reports 108, accounts receivable management tables, invoices, and other various management information 109 are output. On the other hand, the shipping information of ready-mixed concrete sent from the delivery tape e for same-day shipping at each factory is sent to computer center 1.
01 organized by factory and cooperative terminals 1
The 20 printers 120d print out a factory-specific shipping management table 121, a factory-specific backlog management table 122, and other information for association management.

〔Effect of the invention〕

This invention stores a shipping schedule at a ready-mixed concrete factory in a memory in a microcomputer, and sets a key code for each series of data corresponding to each shipping destination among the stored data. The operator of the ready-mixed concrete factory can perform complex shipping management such as changing the quantity of shipments at the time of shipment by simply inputting a key code through the operation console 5 connected to the microcomputer 1 of the shipping control device 105. This allows for easy and accurate shipping management.

In addition, the measuring operation of the cement weighing machine, which is absolutely essential for shipping ready-mixed concrete, which is a feature of this invention, is captured and included as additional data in the delivery tape e (shipping tape) to the cooperative. As a result, the following effects can be obtained.

In other words, even if a ready-mixed concrete factory independently sells orders to a certain construction site and cannot obtain accurate information because the data is not entered into the system of the present invention, it is still possible to actually ship the ready-mixed concrete. The actual value (shipment sales data) can be tracked at a later date by measuring the number of times the cement weighing machine is used.
Cooperative managers can easily clarify the cause and effect relationship between shipment sales data and actual ready-mixed concrete shipment data based on the number of measurements by the cement weighing machine, and learn about the fraud and improve the effectiveness of cooperative management. You can aim and achieve your goals.

Furthermore, since the shipping management device of the present invention is linked to a computer service network using a communication line, it is possible to accurately and efficiently save labor in the operation of a ready-mixed concrete cooperative, and to modernize the ready-mixed concrete cooperative. It can contribute to the development and improvement of constitution.
