Description

Description: TECHNICAL FIELD The present invention relates to a centrifuge which is operated by calling operating conditions stored in a storage device.

[Conventional technology]

In the operation operation of the centrifuge, it is uncomfortable if the operation time ends at midnight or when the client for the centrifugation sample is absent, so adjust the operation time in such cases. There is a need.

Further, in the centrifugation by the sedimentation equilibrium method, first, a high-speed rotation improves the rise of the velocity gradient, then a low-speed rotation is performed, and the velocity gradient is returned, so that the separation layer can be widened in a short time and the separation efficiency can be improved. Can be improved.

In order to automatically control such operating conditions, in the conventional operation control device for a centrifuge, a plurality of operating conditions are stored in advance in a storage device, and these operating conditions are stored individually or continuously. I try to call and drive.

Fig. 6 shows the operation procedure for the conventional memory operation. To perform the memory operation, set the operating conditions by the same operation as the above-mentioned normal operation, then specify the record switch 9 and the memory number with the numeric keypad 14 and enter. The operating conditions are stored in the RAM 22 of the storage device by the switch 15. To recall the stored operating conditions, press the call switch 8 and enter the memory number on the numeric keypad.
Specify with 14, call with enter switch 15, and start operation with start switch 10.

FIG. 7 is an operation procedure for continuously calling a plurality of conventional operating conditions from a storage device, and FIG. 8 is a flowchart of the operation program of FIG. 7. The operation procedure will be described below with reference to FIGS. 7 and 8. To explain, first, the continuous switch 16 is pressed to issue an instruction of continuous operation to the control unit, and then the same operation as the above memory operation is performed. In the operation example shown in FIG. 7, in order to continuously use memory number 1 and memory number 2, each operating condition is registered in the memory section. Meanwhile, ROM1
The program shown in Fig. 8 is installed in 9 so that the operating conditions can be continuously called.

[Problems to be solved by the invention]

In the conventional centrifuge operation control method, a continuous switch 16 is provided to determine whether to operate continuously under a single condition or to sequentially call a plurality of operating conditions. Since it had to be operated, there was a problem in terms of operability.

The present invention solves the drawbacks of the prior art and allows a plurality of operating conditions automatically stored in a storage device to be sequentially called and operated without operating an operation switch for continuous operation. The purpose is to provide.

[Means for solving problems]

In the present invention, a specific memory number different from the preset memory number is provided for continuous operation, the operating conditions are registered in the storage device in the order of the specific memory numbers, and the first registered operating condition is the first memory number. Is called to operate the centrifuge, and when the operation is completed, the operating condition registered with the next memory number is automatically called, and the operation is sequentially continued.

[Action]

In the present invention, when a plurality of operating conditions are continuously called to operate the centrifuge, a specific memory number is used. For example, the first operating condition is stored in the memory number “0” and the next operating condition is stored in the memory. Register to the number "9" and call the specific memory number "0" with the call switch to start operation.
When the operation is completed, the operation condition registered in the next memory number "9" is automatically called and the operation is continued sequentially. Therefore, the conventional operation switch for continuous operation is It becomes unnecessary and the operability of driving improves.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the present embodiment, an operation procedure when a plurality of operating conditions are continuously called from a storage device, and FIG. 2 is a flow chart of the operation program of FIG. 1. The operation procedure will be described.

First, set specific memory numbers "0" and "9" for continuous operation, register the first operating condition in memory number "0", and the next operating condition in "9". Then, the call switch 9 is turned "on" to call "0". When the memory number "0" is called for the first time, the operation program is configured to call the contents of the memory number "9" at the end of the first operating condition. The next operating condition is automatically called and the operation continues.

It should be noted that, by using the LED memory indicator 7 of the segment structure shown in FIG. And when operating under the following operating conditions: The state of continuous operation can be displayed.

As described above, according to the present embodiment, it is possible to sequentially call up a plurality of operating conditions from the storage device and operate the centrifuge without using an operation switch for continuous operation. Operability can be improved. Further, since the operation switch is unnecessary, the cost can be reduced.

〔The invention's effect〕

The method according to the invention eliminates the drawbacks of the prior art,
Even if the operation switch for continuous operation is not operated, a plurality of operating conditions stored in the storage device can be automatically called in sequence to control the operation of the centrifuge.
