Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings and embodiments.

1 is a view schematically showing an egg sorting apparatus according to an embodiment of the present invention, Figure 2 is a view showing a load cell shown in FIG.

1 and 2, the egg sorting apparatus according to an embodiment of the present invention measures the weight of the egg supplied from the egg supply unit 10 and the egg supply unit 10 for supplying eggs not shown from the outside The load cell 20, the load cell support 6 supporting the load cell 20, the dustproof rubber 4 attached to the load cell support 6, and the transfer device 30 for transferring eggs via the load cell 20. ), A proximity sensor 54 installed in the transfer device 30 to detect the transfer of eggs, a plurality of solenoids 50 for sorting the eggs transferred by the transfer device 30 according to the weight, and each A sorting table 70 for aligning the plurality of eggs sorted and released by the solenoid 50 and a weighing signal WS from the load cell 20 are converted into digital measurement data and each solenoid is converted according to the converted measurement data. Control 50 to sort eggs by weight And it is as well provided with a controller 40, a display for displaying the measurement data from the controller 40, device 60 for outputting the measured data.

The egg supply unit 10 arranges the eggs collected at the poultry farm and supplies the sorted eggs to the load cell 20 one by one.

The load cell 20 is a weight (weight) sensor for measuring the weight of the egg and supplies measurement data corresponding to the weight of the egg supplied from the egg supply unit 10 to the controller 40. To this end, the load cell 20 is a measuring unit for measuring the weight of the egg placed in the egg measuring basket 22 and the egg measuring basket 22 to which the egg supplied from the egg supply unit 10 is placed several to several tens of times. (24).

The measuring unit 24 weighs the eggs at high speed through several to several tens of times while the eggs are placed in the egg measuring basket 22 through the measuring unit 24 from the moment when the transfer signal is supplied from the proximity sensor 54. Is measured and supplied to the controller 40.

Accordingly, the load cell 20 is instantaneously measured by measuring the weight of the egg several to several tens of times the error of the weight of the egg is measured to be less than 0.1g to improve the reliability of the weighing of the eggs being transferred.

On the other hand, the weight measurement signal (WS) measured by the load cell 20 is a load cell 20 due to a long time use and when the temperature is large, such as summer / winter when the temperature is large, and when the load cell 20 is contaminated by foreign matter on the eggs The zero point should be corrected periodically or non-periodically because it depends on at least one of the modified cases.

As a method for correcting the zero point of the load cell 20, first, the load cell 20 is manually corrected in the system. Then, if the value within ± 5g of the manually corrected load cell 20 value is automatically corrected to the set value without the need for manual reset. However, if more than ± 5g of the corrected load cell value, the user notifies the user of a message such as an alarm that manual zero calibration is required without performing automatic calibration to the set value. Accordingly, the user inputs the value of the load cell to correct the zero point of the load cell 20.

The anti-vibration rubber 4 is installed between the load cell support 6 supporting the load cell 20 and the body of the sorting device so that vibration generated by the drive of the transfer device 30 by the electric motor is applied to the load cell 20. It is blocked from being transmitted to the measuring unit 24. That is, since the load cell 20 generates a measurement error of about 2g due to mechanical vibration, the anti-vibration rubber 4 blocks electrical vibration and mechanical vibration from being transmitted to the load cell 20 at the same time. Accordingly, the load cell 20 more accurately measures the weight of the egg placed in the egg measuring basket 22 to supply the weight measurement signal WS to the controller 40.

The transfer device 30 is a conveyor rotating by an electric motor, and rotating gears are installed at both ends, and a transfer chain is installed between both rotary gears to transfer eggs via the load cell 20.

This, proximity sensor 54 is initially installed on one side of the transfer device 30 through a test method to set the position. In the test method of the proximity sensor 54, first, two eggs having a weight difference of 10 g or more are supplied to the load cell 20 to measure the weight of the eggs. That is, the weights are measured while moving the small eggs and the large eggs side by side, and the weights are measured after changing the order of the large eggs and the small eggs. This process is repeated at least three times while moving the position of the proximity sensor 54. Thereafter, the number 1 to 10 is ignored and the number 11 to 20 are checked, and the proximity sensor 54 is installed at one side of the transfer device 30 corresponding to the place where the error is small even when the order of eggs is changed. Through the test method of the proximity sensor, by installing the proximity sensor 54 where the error is small, it is possible to minimize the error in the selection of eggs.

On the other hand, one side of the transfer device 30 is provided with a voltage regulator 52 for adjusting the magnitude of the voltage applied to the plurality of solenoids (50). Since the voltage regulator 52 has to operate the solenoid 50 in order to sort eggs at a desired position, the voltage can be variably adjusted so that the eggs can be sorted without hesitation.

Each of the plurality of solenoids 50 is placed in the egg transfer basket 32 of the transfer device 30 in accordance with the selection signal from the controller 40 to sort the eggs being transferred. That is, each solenoid 50 is released from the egg transfer basket 32 to the egg being transported to be discharged to the sorting table (70). At this time, each of the solenoids 50 is set by the voltage regulator 52, the force to release the egg from the egg transfer basket (32).
