のを待機する。Next, the operation will be described with reference to FIG. First, the determination controller 38 sets the standard value of the sorting object, measures the weight of the container 26 in advance, and
The air cylinders 18, 18 are controlled so that the two lifting arms 22, 22 are at the raised position, and the container 26 is brought to a position near the lower end of the charging duct 32 (position X in FIG. 4) (step). In this state, the input duct 32
When the start-up switch 42 is operated (step), the air cylinders 18 and 18 are controlled so that the two elevating arms 22 and 22 are lowered, and the container is placed on the container 26. 26 is placed on the weighing dish of the electronic balance 12 (Y position in FIG. 4, step). Then, the total weight of the object to be sorted and the container 26 is measured by the electronic balance 12, the weight of the object to be sorted is calculated, and it is determined from the calculation result whether or not the weight is appropriate (step). Further, in accordance with the determination, for example, if it is appropriate, one of the lifting / lowering arms 22 is raised, and the other lifting / lowering arm 22 is kept at the lowered position to have an inclined posture as shown in FIG. Of the container 26 into one of the separation ducts 34 (step). If the determination is inappropriate, the lifting arms 22, 22, which are kept at the raising and lowering positions, are controlled in reverse, so that the container 26 is set to the inclined posture in the opposite direction, and the objects to be sorted are transferred to the other separation duct 34. throw into. Then, the lifting arm 22 at the lower position is raised to set the container 26 to the X position in FIG. 4 (step), and the apparatus waits until the next object to be sorted is input and the start switch 42 is operated.

Therefore, it is possible to replace the electronic balance 12 with an optimal weight measurement range according to the total weight of the sorting object and the container 26. Reference numeral 50 shown in FIG. 2 denotes fixing means for fixing the electronic balance 12 to the base 10 so as to be easily separable. Although the structure of the fixing means 50 may be any structure, one example is as follows. That is,
A dovetail projecting from the rear surface of the electronic balance 12 is provided.
It is easily fixed to 0 with a screw.

You may do it. Further, the position and the inclination posture of the container 26 are controlled using the air cylinders 18, 18.
The invention is not limited thereto, and a hydraulic cylinder or the like may be used, or a configuration using a motor or the like may be used. And cover 3
The door 36 of 0 is not limited to one-sided opening, and may be a double door or the like. Further, if the cover 30 can be relatively easily separated from the base 10, the door 36 is not required. Here, if the object to be sorted is light, the cover 30 is effective to eliminate the influence of wind and the like at the time of weight measurement. However, if the object to be sorted is medium-sized, the influence of wind and the like is very small. It is small and does not necessarily require the cover 30. Further, instead of starting the operation by operating the start switch 42, it is also possible to detect by the appropriate means that the sorting object has been inserted into the input duct 32, and to start the operation in accordance with this detection signal. In addition, if the objects to be sorted are regularly supplied, the operation of the apparatus of the present invention may be periodically repeated so as to be synchronized with the operation.
