DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for continuously measuring the volume, weight and specific weight of an object to be measured such as fruits and root vegetables, continuously determining the state of cavities and quality, and discharging the waste according to the determination result. The present invention relates to a continuous measurement device that can be used.

[0002]

2. Description of the Related Art Conventionally, when measuring or discriminating a hollow state of a fruit such as a watermelon without destroying the fruit, there are known methods of discriminating by hitting sound or sound waves, and detecting and measuring electric resistance. However, there is a problem that sufficient discrimination accuracy cannot be obtained in any case. Therefore, the weight and volume of the DUT are first determined, and the specific weight of the DUT is determined from the weight and the volume. We proposed a measuring device that measures without performing. (Japanese Patent Application 2-1
No. 39060) This measuring device measures the weight of an object to be measured by a weight sensor using a strain gauge, and uses a capacitance measuring cover large enough to cover the object to be measured. A high-frequency voltage is applied between the cover and a conductor on which an object to be measured is interposed in the cover by interposing an object, and a capacitance of a gap between the cover and the object to be measured is applied. Is measured by a capacitance meter, the volume of the object to be measured is measured based on the capacitance, the specific weight is calculated by the weight and the volume, and the cavity state of the object to be measured is measured. It is like that.

[0003]

However, in the embodiment of the measuring device proposed above, the objects to be measured are individually carried in, the hollow state thereof is measured, and after the measurement, the objects are individually carried out. Therefore, loading and unloading becomes troublesome, and there is a problem that the workability is poor. In addition, when loading and unloading are performed mechanically by a robot or the like, there is a problem that the structure becomes complicated. . On the other hand, the object to be measured is vacuum-adsorbed by a suction cup, or pressed by a robot arm and conveyed, and the measuring device is provided in this conveying process,
A proposal to measure the cavity state is also proposed (Japanese Patent Application Hei 2-
No. 407252), when the object to be measured is adsorbed or pressed and transported, there is no problem if the object to be measured is relatively hard, such as an apple, and relatively light in weight. It is heavy, and it is difficult to control the suction or pressure bonding for those that are relatively fragile, and there are some difficulties in practicality.In addition, a complicated device for transporting by suction or pressure bonding is required, There was a problem that the cost increased as a whole.

[0004] It is an object of the present invention to determine the hollow state and quality of an object to be measured, such that the object to be measured is large, such as a watermelon, and
Even if the object is heavy, it can be measured continuously, and the structure can be simplified while the object to be measured can be transported more stably than when it is transported by suction or pressure bonding. It is an object of the present invention to provide a measuring device capable of discharging an object well.

[0005]

According to the present invention, a plurality of trays each having a mounting body on which an object to be measured is mounted, a transporting body for transporting the tray, and an object mounted on the mounting body described above are provided. In a continuous measurement device for an object to be measured comprising a cavity state measuring device for measuring a cavity state of the object to be measured and a discharge unit for discharging the object to be measured from the mounting body, the cavity state measuring device includes: A volume measuring unit having a contact portion that comes into contact with the measurement object, a conductor that can move up and down with respect to the tray, and a capacitance measurement cover that faces the conductor, and a weight of the measurement object And a specific weight calculation unit that calculates a specific weight based on the weight information measured by the weight measurement unit and the volume information measured by the volume measurement unit. .

[0006]

Since the object to be measured is transported by driving the carrier while being placed on the mounting body of the tray, even if the object to be measured is a heavy object such as a watermelon, it can be transported stably. At the same time, it is possible to perform quality measurement and discharge from the mounting body described above, and when measuring the volume of the object to be measured mounted on the mounting body of the tray, raise the conductor with respect to the tray. The conductor can be brought into contact with an object placed on the mounting body, and the volume of the object can be measured by applying a high-frequency voltage to the conductor in this contact state. Therefore, the volume measurement in the volume measurement unit can be performed with high accuracy, and the accuracy of measuring the quality of the measured object can be improved.

Therefore, even if the object to be measured is a heavy object such as a watermelon, it can be stably conveyed and its cavity state can be continuously measured, and the object to be measured after the measurement is continuously discharged.
In addition, it can be made easily and its workability can be improved.
