BACKGROUND OF THE INVENTION
The present invention relates to the operability of a centrifuge that operates and operates a plurality of rotating bodies under operating conditions desired by a user.
[0002]
[Prior art]
Currently, some centrifuges have several thousand revolutions per minute to hundreds of thousands revolutions per minute depending on the sample to be separated. Recently, a microcomputer has been adopted, and the operability is improved compared to the conventional one. For example, in the Hitachi separation microcentrifuge CS150GX, the operation speed shown in FIG. 3 and the liquid crystal display shown in FIG. 7 are used to set and display the rotational speed, operating time, temperature of the rotating body, and the like. . Fig. 7 shows an example of the basic screen as an example of a liquid crystal screen. In the figure, the set value is displayed in the lower numeric display area of the SPEED, TIME, and TEMP display fields, and the status value is displayed in the upper numeric display area. The When a normal user uses, the operation conditions are set with the operation switch of FIG. The operating conditions set for daily routine work are as follows. When the cursor is moved to the PROG section of the OPTION column in FIG. 7 with the operation switch, the display will eventually display “MEMORY” as shown in FIGS. The screen switches to a screen, where operating conditions such as SPEED, TIME, and TEMP are input and set, and a dedicated number “MEMORY” is assigned and stored in the storage device inside the centrifuge.
[0003]
[Problems to be solved by the invention]
In the above centrifuge, the next time operation, move the cursor to the PROG section in Fig. 7 and enter the "MEMORY" dedicated number on the program dedicated screen to call up the operating conditions stored in Fig. 7 "Basic screen". It is a mechanism to set. Moreover, when using temporarily, it does not memorize | store in "MEMORY", but will set and drive every time on the "basic screen" of FIG. 7, and the troublesome operation that an individual user sets an operating condition each time will be carried out. It was necessary. In addition, when storing in “MEMORY”, there is a problem that the operation is complicated and the usability is poor.
[0004]
An object of the present invention is to provide means for solving the above problems and improving reproducibility while improving operability and simplification.
[0005]
[Means for Solving the Problems]
The above purpose is to store and store information on driving conditions, rotating bodies, etc. as driving history in a storage device for each operation, display the history according to the user's purpose of use, select desired information from the history, This is achieved by setting a value.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
1, 2, 10, and 11 mainly show an embodiment according to the present invention. In FIG. 1 and FIG. 2, a rotating body 1 in which a sample is placed is rotationally driven by a driving device 3 in a rotating chamber 2. The user operates the operation switch 7 as shown in FIG. 3 as an example to rotate the rotating body 1 or the driving device 3, the operation time, the temperature of the rotating body 1 or the rotating chamber 2, or the rotating body 1 or the driving device 3. Control items relating to acceleration gradient or deceleration gradient up to a predetermined speed and other operations are set, and the control device 5 receives the information. In FIG. 1, the rotating body information input device 4 identifies the presence or absence of the rotating body 1 such as a sensor for RLM (automatic rotor life management system) used in the Hitachi separation ultracentrifuge CP100α type. At the same time, information on the rotating body 1, for example, the rotating body type, serial number, number of operations, accumulated rotation speed, and the like is taken from the rotating body 1 and the data is transferred to the control device 5.
[0007]
In FIG. 2, it is assumed that the user manually inputs information on the rotating body to be operated and used to the rotating body information input device 4 outside the rotating chamber 2, and the after-input rotating body information input device 4 is a control device. The information is transferred to 5. After receiving the information from the operation switch 7 and / or the rotating body information input device 4, the control device 5 stores the information in the storage device 8 as a list as shown in Table 1, for example. At that time, the control device 5 also takes in information from the time measuring device 9 that measures the operation time and date / time (year / month / day, time) of the centrifuge, and similarly stores the information in the storage device 8. Further, the control device 5 displays all or a part of them on the display 6 as operation condition setting values, or the values of the operation state (actual rotational speed, operation time, temperature, etc.) of the centrifuge as state values. To do. Display examples are shown in FIGS. The operation will be described with reference to the flowchart of FIG. When the power of the centrifuge is turned on, the “basic screen” of FIG. 4 is displayed on the display 6, and when the user operates the cursor key of the operation switch of FIG. 3 (for example, when the upward cursor key is pressed) ), The display 6 switches to the “used rotor list” screen of FIG. The “used rotor list” in FIG. 5 displays the operation history of the rotor (rotor) used in the past. In this example, the rotor type and the last use date and time of each rotor are displayed. If the rotor that the user wants to use is present in the “used rotor list”, the rotor is selected by operating the cursor key. When “1” is selected, the display 6 returns to the “basic screen” of FIG. 4 and sets and displays the operating conditions at the time of final use of the selected rotor as set values. In the “basic screen” of FIG. 4, the set value is displayed in the lower numeric display section of the SPEED, TIME, and TEMP display fields, and the status value is displayed in the upper numeric display section. If the rotor to be used is not in the “used rotor list” in FIG. 5, the display returns to the “basic screen” in FIG. Once the operating conditions are set, start the operation. The control device 5 takes in the date and time (year / month / day / time) data at the start from the time measuring device 9. The rotor is automatically identified by the rotating body information input device 4, and the control device 5 receives the rotating body (rotor) information. When the rotor cannot be automatically identified, the rotating body information can be manually input to the rotating body information input device 4 as shown in the flowchart of FIG.
[0008]
The control device 5 stores and saves the rotating body (rotor) information, operation conditions, and date and time (year / month / day / time) data at the start in the storage device 8. Thereafter, the centrifuge operates for a set predetermined operation time, and decelerates and stops. The control device 5 can also fetch and store date / time (year / month / day / time) data at the time of deceleration / stop from the timing device 9 in the storage device 8. After the operation, the control device 5 registers or updates the rotor information stored in the storage device 8, the operating conditions, and the date data at the time of start or stop in the “used rotor list” in the form of adding to the rotor format. . In the next operation, the used rotor can be selected based on the registered or updated “used rotor list”, and the operating conditions and the like can be easily set. Examples of data stored and saved in the storage device 8 are shown in Table 1 below.
[0009]
[Table 1]

[0010]
Here, the data in Table 1 is the rotor type, serial number or dedicated code, rotation speed, operating time, operating temperature, acceleration gradient (ACCEL), deceleration gradient (DECEL), tube or bottle used, dedicated adapter, sample , Solution / solvent / additive, operation date / time, user name, and other user special instructions.
[0011]
Based on these data, for example, the “use rotor list” in FIG. 5 can display the operating conditions such as SPEED, TIME, TEMP, etc. together with the rotor type as shown in FIG. Display various data for each operation date / time or each sample used, or display all usage data for each user's request item depending on the size and capacity of the display 6 and operate from those data It is also possible to select data to be set and set it on the display 6. In addition, when displaying the history for each user, it can be realized by inputting a code unique to the user with the operation switch 7 and storing the input code in the storage device 8 as one of the operating conditions.
[0012]
【The invention's effect】
According to the present invention, the rotating body or operating conditions that have already been used can be easily displayed and searched, and the user can select the content to be driven next from the displayed information content and set it as a set value. The improvement of reproducibility can be aimed at with improvement of simplicity and simplification.
