この自動計量装置には、その用途や計量する粉粒
体の性質によつて種々の計量・排出方式（計量動
作モード）が設定されるが、ここで、計量・排出
方式の一例を以下に述べる。 Automatic weighing equipment automatically measures, blends, and supplies powder and granular raw materials, etc., and occupies an important position in the production line of factories that handle many types of powder and granular raw materials. There is. by the way,
Various weighing/discharging methods (measuring operation modes) can be set for this automatic weighing device depending on its purpose and the properties of the powder or granular material to be measured. .

式。 Type 1 weighing method: First, multiple material feeders are placed in one automatic weighing device. Then, only a certain material feeding machine starts feeding material into the weighing hopper of the automatic weighing device, and when this feeding amount reaches the set amount, the material in the weighing hopper is discharged, and after the weighing hopper is empty, the next material is fed into the weighing hopper. A method in which the material feeding machine starts feeding materials, and the same operation is performed sequentially thereafter.

このコントローラと自動計量装置との組合わせで
所望の方式による自動計量システムを構成する。 By the way, since the operation of an automatic weighing device is controlled by a controller, when configuring a weighing system using a desired weighing and discharging method, a controller that stores the operation of the weighing and discharging method is manufactured,
A combination of this controller and an automatic weighing device constitutes an automatic weighing system according to a desired method.
しかしながら、上述した従来のコントローラを

た。 However, in the weighing system using the conventional controller described above, the controller that controls the automatic weighing device is a dedicated controller that stores only the operation of one weighing/discharging method. When changing the discharge method, there is a drawback that the controller itself must be replaced or the settings changed, and in factories where multiple automatic weighing devices with various weighing and discharging methods coexist, it is necessary to change the controller for each weighing and discharging method. Since a dedicated controller must be manufactured for each, this is disadvantageous in terms of time and cost.

に基づいて自動計量装置を制御するものである。 In view of the above-mentioned circumstances, the present invention provides a controller for an automatic weighing device that can support a plurality of weighing and discharging methods, and has a plurality of mode-specific memories each storing control programs for different weighing operation modes (weighing/discharging methods). One of the storage areas for each mode is selected, and the automatic weighing device is controlled based on the control program in the selected storage area for each mode.

る。 As explained above, according to the present invention, a plurality of mode-specific storage areas are provided for storing control programs for different weighing operation modes (metering/discharge methods), and any one of the mode-specific storage areas is Since the automatic weighing device is controlled based on the control program in the selected mode storage area, it has the advantage of being able to support multiple weighing and discharging methods. Even when creating a weighing system that includes multiple automatic weighing devices using the discharge method, it is extremely simple because you can prepare the same controller for the number of automatic weighing devices and select the desired operation mode for each at the site. A weighing system can be created. In addition, when an automatic weighing device wants to switch to a different weighing/discharging method on a trial basis, or when it is necessary to change the weighing/discharging method due to a change in material (powder or granular material), it can operate instantly. Since the modes can be switched, the desired weighing and discharging method can be changed without interrupting the operation of the weighing system.
