  When the temperature and humidity of the environment where the molding machine is installed change, the color of the resin molded product manufactured by the molding machine changes. In addition, since a sufficient amount of pulverized material is not stored in the raw material hopper, the blending ratio according to the recipe cannot be obtained, and the color of the resin molded product manufactured by the molding machine may change. . In these cases, the recipe is finely adjusted in order to restore the color of the resin molded product.

  Every time the color of the resin molded product changes, the fine adjustment of the recipe is repeated. Over time, the operator may want to return the contents of the recipe to the contents after the previous fine adjustment. However, the content after the previous fine adjustment is different from the content of the recipe stored in the memory. Therefore, unless the operator remembers the contents after the previous fine adjustment, the contents of the recipe cannot be returned to the contents.

  An object of the present invention is to provide a metering and mixing device capable of returning the content of a recipe to the content after the previous change when the content of the recipe is repeatedly changed.

  In order to achieve the above object, a measuring and mixing apparatus according to the present invention includes a recipe storage unit that stores a plurality of recipes that define conditions of a measuring and mixing operation for measuring and mixing a plurality of types of raw materials, and temporarily stores the recipe.

  The recipe storage means stores a plurality of recipes that define the conditions of the metering and mixing operation in which a plurality of types of raw materials are weighed and mixed. In the weighing and mixing operation, the recipe is selectively read from the recipe storage unit, and the recipe is temporarily held in the recipe holding unit. Then, the contents of the recipe held in the recipe holding means are not changed, or after the contents of the recipe held in the recipe holding means are changed, the weighing and mixing operation is controlled according to the contents.

  When the control of the metering / mixing operation is executed, the contents of the recipe used for the control are held in the history holding means as a history. The contents of the recipe held in the history holding means can be read later from the history holding means and held in the recipe holding means. Therefore, when the change of the content of the recipe is repeated, the content of the recipe held in the recipe holding means can be returned to the content after the previous change.

  The recipe whose contents have been changed is held in the history holding unit and may be overwritten or newly written in the recipe storage unit, or only stored in the history holding unit and not written in the recipe storage unit. Also good.

  When the recipe whose contents are changed is configured to be writable in the recipe storage means, it is preferable to provide means for inputting whether or not to write the recipe in the recipe storage means. This prevents the contents of the recipe stored in the recipe storage means from being automatically rewritten or a new recipe being automatically added to the recipe storage means against the operator's will.

  It is preferable that a history display unit is provided in the weighing and mixing apparatus, and the history held in the history holding unit is displayed on the history display unit side by side in time series. Thereby, it is possible to quickly find out the contents of the recipe to be used for the weighing and mixing operation from the history displayed on the history display means. As a result, the labor of the operator can be reduced.

  Each recipe stored in the recipe storage unit is given a different number, and the history display unit displays the contents of each recipe in the history stored in the history storage unit together with the number corresponding to the recipe. Preferably it is displayed. Thereby, when the content of the recipe in the history held in the history holding unit is changed from the content of the recipe stored in the recipe storage unit, based on the number displayed together with the content of the changed recipe Thus, the recipe before the change can be easily specified.

  The raw material may contain a pulverized material. When the remaining amount of the pulverized material is not sufficient, the color of the resin molded product manufactured using the raw material containing the pulverized material may change. In such a case, a change in the color of the resin molded product can be suppressed by changing the content of the recipe. And whenever the content of a recipe changes, whenever the color of a resin molded product changes, the content of a recipe can be immediately returned to the content after a previous change as needed.

  The weighing and mixing apparatus may be provided with operation means operated by an operator. In this case, the recipe stored in the recipe storage unit may be selectively read based on the operation of the operation unit, and the recipe may be held in the recipe holding unit. Further, the contents of the recipe held in the recipe holding means may be changed based on the operation of the operation means. Furthermore, the contents of the recipe in the history held in the history holding means may be selectively read based on the operation of the operation means, and the recipe having the contents may be held in the recipe holding means.

  According to the present invention, the contents of the recipe held in the recipe holding means are not changed, or after the contents of the recipe held in the recipe holding means are changed, the weighing and mixing operation is performed according to the contents. Be controlled. When the control of the metering / mixing operation is executed, the contents of the recipe used for the control are held in the history holding means as a history. The contents of the recipe held in the history holding means can be read later from the history holding means and held in the recipe holding means. Therefore, when the change of the content of the recipe is repeated, the content of the recipe held in the recipe holding means can be immediately returned to the content after the previous change.
