To provide an egg checker that can check eggs and (3) greatly streamline egg checking work.

Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. 1 in the diagram
1 is the egg checker main body, and a guide frame 3 for guiding the tray 2 shown in FIG. 5 is erected on both sides of the top surface in the longitudinal direction. A transparent glass plate 4 is disposed on the upper surface, and the tray 2 is inserted from the entrance side 5 and moves on the glass plate 4 while being guided by the guide frame 3.

As shown in FIG. 5, the tray 2 has six egg storage sections H formed in one row, making a total of 22 rows. The first row, the third row...the 21st row, odd numbered rows, all have egg storage sections H formed on the same line with respect to the longitudinal direction of the tray 2, and the egg storage sections H are formed on the same line in the longitudinal direction of the tray 2. The 22nd even-numbered rows are arranged at positions shifted by half the size of the egg storage section H from the above-mentioned odd-numbered rows, and are all formed on the same line in the longitudinal direction of the tray 2. ing. An egg checking section 6 is provided near the entrance side 5 of the main body 1 in order to check the eggs E set on the tray 2 in which the egg storage section H is formed in the manner described above. . Various sensors can be considered as the egg checking section 6, but in this embodiment, an infrared projector Sa and an infrared receiver Sb are combined into one set, and a plurality of sets are arranged. The manner of arrangement thereof is determined in accordance with the manner of the egg storage section H formed in the tray 2.

That is, since the tray 2 in this embodiment is the tray 2 shown in FIG. By setting the eggs E on the tray 2 and moving it along the longitudinal direction of the inspection area of the infrared sensor S, all the eggs E set on the tray 2 can be checked. . In order to check eggs in this way, a mounting plate 7 is installed on the upper part of the entrance side 5 of the main body 1, and six infrared receivers Sb corresponding to the egg storage areas H in the first row are arranged on the mounting plate 7. At the same time, an infrared projector Sa forming a pair with the infrared receiver Sb is provided on the lower side of the glass plate 4 inside the main body located directly below the infrared receiver Sb.
Arrange six pieces in the same way. In the same way, six infrared receivers Sb corresponding to the second row of egg storage sections H are arranged on the mounting plate 7, and a pair of infrared projectors Sa are arranged inside the main body 1.

Next, the signal switching section 8 is arranged on the guide frame 3 erected on both sides of the main body 1. This signal switching unit 8 is a micro switch 10 that presses a contact 9 in response to insertion and removal of the tray 2.
are arranged at predetermined intervals, and are used to switch the detection signal sent by the egg checking unit 6 to be sent to the operation circuit 11 corresponding to the egg being checked by the egg checking unit 6. It is.

In this embodiment, a first
Micro-switches 10 are sequentially arranged in the row, third row, .

That is, when the front end Ha of the egg storage section H in the first row reaches the inspection area of the infrared sensor S disposed near the entrance side of the main body 1 in order to check eggs in odd rows, the above-mentioned The six sets of infrared sensors S that are checking the eggs E in the first row and the six operating circuits 10 arranged corresponding to the eggs E in the first row are each closed circuits. A micro switch 10a like this is provided. Then tray 2 moves and
Immediately before the rear end Hb of the egg storage section H in the row passes through the inspection area of the infrared sensor S for checking eggs in the first row, the first row is connected to the closed circuit. A micro switch 10b is provided to open the circuit between the corresponding operating circuit 11 and the infrared sensor S. That is, the distance between the micro switches 10a and 10b arranged on the guide frame 3 is 5.
As shown in the figure, the distance t is approximately the same as the distance between the front end Ha and the rear end Hb. Next, when the front end Ha of the egg storage section H in the third row also moves to the inspection area of the infrared sensor S, it is arranged in correspondence with the infrared sensor S and the eggs E stored in the third row. A micro switch 10a is provided to close the operating circuit 11. The distance between the micro switch 10a and the previous stage micro switch 10b is the same as the rear end Hb of the egg storage section in the first row and the front end Ha of the egg storage section H in the third row. 5
They are indicated at intervals t' in the figure.

In this way, the microswitch for closing the circuit between the infrared sensor S and the operating circuit 11 corresponding to the row in which the infrared sensor S is checking the eggs, and the microswitch for opening the circuit are alternately operated. It is placed on the guide frame 3 on the right side.

Similarly, on the left guide frame 3, there is an infrared sensor S for checking the eggs E stored in the even-numbered egg storage sections.
A micro switch 1 for closing the operation circuits 11 arranged corresponding to the number of rows of eggs being checked.
0a and a micro switch 10b for opening the circuit are arranged alternately.

Now, as for the operation circuit 11, the same number of them are arranged corresponding to the egg storage sections H formed on the tray 2, and the same number of the operation circuits 11 are arranged to correspond to the egg storage sections H formed on the tray 2. egg E,
This is a circuit for notifying the lighting indicator lamp 12 by lighting it. Various circuits can be considered as operating circuits for achieving this purpose. For example, when the signal output of the egg-checking sensor S is input to a computer via an input/output device and an input/output interface, and is stored in the memory (RAM) in the computer, and the tray 2 is moved to the final position. , the information in the above memory is sent to the CPU
The lighting indicator lamp 12 may be displayed based on the information.

In this embodiment, an example using a thyristor 13 will be shown. That is, as shown in FIG. 8, the anode A of the thyristor 13
Connect the side to the ■ side of the power supply V, and connect the gate G side to the relay 14,
15 normally open contacts 14a, 15a, diode D, resistor R
Similarly, connect to the ■ side of the power supply V via. On the other hand, the cathode K side is the normally open contact 16a of the relay 16, and the lighting indicator lamp 1.
Connect to the ■ side of the power supply E via 2.

In order to operate the operating circuit 11, the output circuit of the infrared sensor S is connected to the relays 14 of the operating circuit 11 corresponding to all the egg storage sections H passing through the inspection area of the infrared sensor S.

That is, 12 infrared sensors S are connected to 11 relays 14, respectively. Next, the micro switch 10 is connected to the relay 15. The above connection is 1 of egg storage part H.
Do this with one piece per column.

The relays 16 of all the operating circuits 11 are connected to a reset device 17 provided on the entrance side 5 and approximately in the center of the guide frame 3 of the main body 1. Next, reference numeral 18 is a tube arranged to irradiate the light of the lighting indicator lamp directly upward.

Next, the operation will be explained based on the above configuration.

First, the tray 2 with eggs E set thereon is inserted into the egg storage section H from the entrance side 5 of the main body 1 along the guide frame 3. This tray 2
As a result, the contact 9 of the reset device 17, which is disposed on the entrance side and then approximately in the center, is pressed. As a result, the normally open contacts 16a of the relays 16 of all operating circuits 11 are closed. Next, as the tray 2 is moved in the direction of the arrow X, the front end Ha of the egg storage section H in the first row comes into the inspection area of the infrared sensor S. At this time, the tip of the tray 2 presses the contact 9 of the micro switch 10a arranged on the right guide frame 3. As a result, relay 1 of operating circuit 11
The normally open contact 15a of No. 5 is closed.

For this reason, the operating circuit 11 enters a standby state.

At this time, the egg E passing between the infrared emitter Sa and the infrared receiver Sb is a hatched egg, so when the infrared rays are blocked, the signal is sent to the relay 14 and the normally open contact 14a.
closes momentarily. As a result, a closed circuit is formed in the gate circuit of the thyristor 13, so the thyristor 13 is turned on, and current flows between the power supply V, the thyristor 13, the normally open contact 16a of the relay 16, and the lighting indicator lamp 12. For this reason, the lighting indicator lamp 12 remains lit until it is reset. The signal from the above infrared sensor is sent to another operating circuit 1.
The signal is also transmitted to relay 14 of No. 1, but the other operating circuits 11 do not operate because they are not in standby mode. Since the lighting indicator lamp 12 is housed in the tube 18, its light is emitted directly upwards, and when the tray 2 is inserted all the way, the eggs E that caused this lighting are individually irradiated from directly below. It is notified that the egg E is irradiated and the infrared rays are shielded, that is, the egg is a hatched egg.

Next, when the tray 2 moves in the direction of the arrow X and the rear end Hb of the egg storage section H in the first row approaches the inspection area of the infrared sensor S, the tip of the tray 2 touches the micro switch 1.
0b to open the normally open contact 15b of the relay 15. As a result, even if the output signal of the infrared sensor is transmitted to the relay 14 next time, the operation circuit 11 in the first column does not operate.

(Of course, at this time, all other operating circuits 11 are not in standby state, so they do not operate.) Then, the front end Ha of the egg storage section H formed in the third row enters the inspection area of the infrared sensor S. When the contact 9 of the micro switch 10a is pressed, the normally open contact 1 of the relay 15 of the six operating circuits 11 corresponding to the third row egg storage section H is pressed.
5a is closed and this operating circuit 11 enters a standby state. That is, since the operating circuit 11 is not put into a standby state between the first and third rows, the operating circuit 11 will not operate even if the frame of the tray 2 passes between the infrared sensors and blocks light.

In the same manner as above, the eggs E stored in the even-numbered egg storage sections of the tray 2 are checked by a micro switch placed on the left guide frame 3, corresponding to the even-numbered rows. This is carried out with the operating circuit 11 disposed in a standby state.

When all of the eggs from the 1st row to the 22nd row have been sampled in this way, the results will be shown by the lighting indicator light located at the bottom of the egg storage compartment H when tray 2 is inserted all the way. 1
Notification is made by lighting up 2. The above-mentioned lighting occurs because when the tray 2 is removed, the pressure on the contact 9 of the reset device 17 is released, and as a result, the normally open contact 1 of the relay 16 is released.
6a is opened, so it is stopped. Then, they will be offered at the next Torei egg check.

In this embodiment, the infrared sensor is used to irradiate the shielded egg E, but one more relay is interposed between the relay 16 and the power supply V, and a lighting indicator lamp is connected through the relay. However, it is also possible to display the eggs E that do not block the infrared sensor S by lighting up. Furthermore, regarding the arrangement of the infrared emitter Sa and the infrared receiver Sb, in this embodiment, the infrared emitter is on the upper side and the receiver S is on the lower side.
b was installed, but in order to prevent the influence of the adjacent floodlight,
Once the light emitter Sa is placed on the upper side and the light receiver Sb is placed on the lower side, the light receiver Sb may be placed on the upper side and the light emitter Sa may be alternately placed next to it.

As described in detail above, the present invention includes an egg checking section consisting of an egg checking sensor arranged on the entrance side of the main body, a signal switching device arranged on the tray guide frame provided on both sides of the upper surface of the main body, The above-mentioned signal switching device puts the machine into a standby state, and when it receives a detection signal from the egg checking section, it becomes an operating state, and the operating circuit for lighting the lighting indicator lamps in the next stage until it is reset; It consists of a lighting indicator lamp that connects to the operating circuit and illuminates the eggs set on the tray individually from below, and detects the eggs on the tray when the tray with eggs set is inserted from the entrance side of the main body. This is an egg checker characterized in that the eggs are checked in the egg section and the results are notified by lighting up a lighting indicator lamp located at the bottom of the eggs that should be displayed when the tray is inserted all the way. (1) To provide an egg checker that can check the hatching status of eggs by simply inserting a tray with eggs set therein, since light blocking by the frame body is not detected, but only light blocking by the eggs is detected. As a result, (2) anyone can easily check eggs without requiring any special skill, and (3)
The present invention has various advantages such as providing an egg checker that can greatly streamline egg checking work.
