Abstract

PURPOSE:To operate smoothly and more automatically a fish body picture input apparatus by detecting automatically the clogging of fish to close a path and thereby prevent the succeeding fish from being transferred therein. CONSTITUTION:When a weight roller is choked with fish, the output of a light receiving sensor is left as L, and electric pulse does not enter the input terminal B of a counting circuit 82 so that subtraction by the counting of said circuit 82 is not carried out. On the other hand, every time a spike drum is rotated by one revolution, fish is sent into a tray while electric pulses are applied from a rotary encoder to the terminal A of the circuit 82 and adding is carried out by the counter so that the accumulated value in the counter exceeds value N0 preset in the circuit 82. Thus the output terminal C of the circuit 82 is held at 1, the output of the light receiving sensor is left as L and the input terminal I and output terminal J of the circuit 85 become L and 1 so that air valves 51, 53 permit a shutter to close a fish path with an air cylinder.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a fish body image input device, and more particularly to a fish body image input device having functions of automatically detecting and automatically removing clogged fish.

(b) Conventional technology Regarding devices for processing input fish body images, there has already been a fish processing system (Japanese Patent Application No. 57-229480), a fish direction identification device (Japanese Patent Application No. 57-104745), and a fish direction identification device (Japanese Patent Application No. 57-104745). No. 57-167380) has been proposed.

However, in any of these devices (a)
Concerning the input of a fish image, a specific means for stopping the fish, positioning it, capturing the image with the photoelectric conversion unit, and then restarting the fish in order to prevent image blurring of the photoelectric conversion unit.

(b) Even if photoelectric conversion is performed while the fish is moving, there is no notice regarding means for preventing image blur or specific means for detecting when the fish has arrived at the imaging range.

Therefore, the inventor of the present application proposed a fish body image input device (Japanese Patent Application No. 1983-1983) that includes the above-mentioned specific means.

(c) Problems that the invention aims to solve Unlike standardized industrial products, fish that live in the natural world have a body length of 1 body, width of 2 bodies, and thickness of 2 bodies, even if they are of the same species.

There is a wide distribution in terms of weight, overall shape, etc. (i) The device described by the inventor in the previous application separates the fish layer by layer using a weight roller and a spike drum, which will be described later, and supplies it to the l.ray, but since the distribution of the fish itself is wide,
Some of them may become stuck between the weight roller and the spike drum, preventing fish from being fed into the tray.

Furthermore, (ii) the device described in the previous application uses a weight roller and a spike drum to intermittently take out fish from the tray, but because the distribution of fish is wide, some fish cannot be taken out from the tray and the fish are stuck in the tray. Sometimes it stays.

Due to the conditions (i) and (ii) above, the fish may not enter the tray or the fish may accumulate inside the tray.

The present invention solves the problems of the prior art described above.

(d) Means for Solving the Problems To achieve this, the present invention provides a means for separating and supplying fish by separating the fish one by one and supplying the fish to the fish imaging position, and a means for performing an imaging operation on the fish at the fish imaging position. A fish body image input device comprising a fish body imaging means for obtaining an image of the fish body, and an intermittent feeding means for intermittently discharging the fish body at the fish body imaging position, a passage detection means for detecting passage of the fish body via the fish body imaging position. , an operation number detection means for detecting the number of times of separation and supply of fish bodies by the fish body separation and supply means, and outputs of the passage detection means and the operation number detection means.

(E) Function The present invention relates to an input device that captures images of fish. ■) Means for automatically detecting and displaying clogged fish or means for removing clogged fish; and 2) Means for automatically detecting and displaying clogged fish; By providing a means for closing the passage to prevent fish from entering, a fish body image input device is realized that enables smooth operation of the device and further automation.

(F) Embodiment FIG. 1 shows an embodiment of the fish body image input device of the present invention. 1 is a vibration trough. The vibrating trough 1 is supported by a leaf spring 2, and when the eccentric crank 3 rotates, the vibrating trough 1 reciprocates left and right.

The vibrating trough 1 is attached with a punched plate 4 with the burr side facing up. When the vibrating trough 1 reciprocates, a frictional force acts between the scales of the fish 5 and the punching plate 4, causing the fish 5 to move in the direction of its head (
In Figure 1, the direction is from left to right). On the scales of fish 5,
Since it has directionality, fish 5 does not move in the direction of its tail. Therefore, when the fish 5 is put into the vibrating trough 1, the fish 5 moves toward the weight rollers described later.

6 is a shutter, 7 is an air cylinder, and 51 is an air valve that switches the flow of high-pressure air. When the air valve 51 determines the direction in which high-pressure air flows according to an electric signal, the air cylinder shaft 7-1 comes out (extends) from the case, or when the air valve 51 changes the direction in which high-pressure air flows in the opposite direction to the above-mentioned direction. The air cylinder shaft 7-1 that had been protruding from the case enters (shrinks) the case.

The shutter 6 is driven by an air cylinder 7-1, and the shutter 6 is driven by an air cylinder 7-1.
It rotates by 0° and closes or opens the passage for the fish 5 on the vibrating trough 1. FIG. 1 shows a state in which the air cylinder 7-1 is extended, that is, when the shutter 6 is open. When the air cylinder shaft 7-1 is retracted, the shark 6 rotates approximately 90 degrees counterclockwise, making the passage for the fish 5 cold.

8 is a spike drum, and a plurality of pins 8-1 are implanted in the circumferential surface. The shaft of the spike drum 8 is coupled to the rotation shaft of the rotary encoder 52 using coupling means (not shown). The rotary encoder 52 is used as a means for detecting the number of rotations, and generates one electric pulse when it rotates once.

In the case of this embodiment, the shaft of the spike drum 8 and the shaft of the rotary encoder 52 are coupled at a rotational speed ratio of 1:1, so that the spike drum 8 rotates and the pin 8-1 is located almost directly above the shaft. When the position is reached (the position where the catfish is hooked), the rotary encoder 52 sends out one electric pulse whose potential level changes from +12V to OV.

A weight roller 9 is supported by a shaft 9-1.

The hole 9-2 of the weight roller 9 is set larger than the shaft 9-1, so if you push the weight roller 9 from bottom to top with a force that overcomes its own weight, the weight roller 9 will close the hole 9-2 and the shaft 9-1. It can be lifted by a gap of 1. 10 is a plate. The receiver has a groove 10-1 cut into the center of the plate 10, and when the spike drum 8 rotates, the pin 8-1
moves between the grooves 10-1. The pin 8-1 is arranged so that the receiver protrudes above the bottom of the plate 10.

The position of the shaft 9-1 is set so that the gap formed between the weight roller 9 and the tray 10 is smaller than the thickness of the fish 5 when the weight roller 9 is sagging due to its own weight.

The fish 5 that has advanced from the vibrating trough 1 is moved to the weight roller 9.
The receiver is stuck between the plate 10 and the plate 10, and cannot move forward. When the spike drum 8 rotates and the pin 8-1 comes close to directly above, the pin 8-1 hooks the crocodile of the fish 5 and moves the fish 5 forward. The fish 5 pushes up the weight roller 9 and moves forward.

Since the weight of the weight roller 9 is applied to the fish 5 from above, a single fish 5 passes through the weight roller 9 only when the pin 8-1 is caught by the crocodile. - The weight roller 9 and the spike drum 8 feed the fish 5 at a rate of approximately one fish per second.

1) is a tray with a concave center. A feather brush 12 rotates counterclockwise and accelerates the fish 5-1 coming out of the weight roller 9. 19 blows out water into the tray 1) with a shower pipe. The water coming out of the shower pipe 19 flows inside the tray 1) and acts as a lubricant, and serves to wash away the fish 5-1. 15 is an air cylinder. 53 is an air valve that switches the flow of high-pressure air. When the air valve 53 determines the flow direction of high-pressure air according to the electric signal, the air cylinder shaft 15-
1 comes out (extends) from the case or air valve 5
3 changes the flow direction of the high-pressure air to the opposite direction to the above-mentioned direction, the air cylinder shaft 15-1 that had come out of the case enters (shrinks) the case. The tray 1) and the cylinder shaft 15-1 are connected via a link. Driven by the air cylinder shaft 15-1, the tray 1) becomes almost horizontal (the state shown in FIG. 1) and changes from the state shown in FIG.
Rotates downward in an arc around axis 1)-1. In the illustrated example, when the air cylinder shaft 15-1 is retracted, the tray 1
) indicates a nearly horizontal state. When the air cylinder shaft 15-1 is extended, the tray 1) rotates clockwise by a predetermined angle and then stops. Therefore, when viewed in the direction in which the fish 5-1 moves, the tray 1) is downward facing. When returning 1 to 1) to almost horizontal, use the air cylinder shaft 15.
Just shorten -1.

When the tray 1) is descending first, the fish 5-1 that came out from the weight roller 9 moves along the slope of the tray 1), and the fish 5-1 in the tray 1) slides down from the tray 1). , the fish 5-1 in tray 1) can be removed.

13 and 14 are a pair of optical sensors, 13 being a light emitting sensor and 14 being a light receiving sensor. A light beam is irradiated from the light emitting sensor 13 to the light receiving sensor 14 through holes 13-1 and 14-1 formed in the tray 1). sensor pair 13
The installation height of the sensor pair is set so that when the fish 5-1 is placed between the sensor and 14, the fish 5-1 blocks the light beam.

The light receiving sensor 14 sends out an electrical output of +12 cm when receiving the light beam from the light projecting sensor 13, and 0 cm when the light beam is interrupted.

The fish 5-1 that has passed through the weight roller 9 is transferred to the feather brush 1.
2), and when it runs through the tray 1) and passes between the opposing pair of sensors, it blocks the light beam, so the passage of the fish 5-1 is detected from the change in the electrical output of the light receiving sensor 14, and the fish 5 -1 detects the position of the fish that has reached the imaging range of the television camera.

16 is a television camera. The television camera 16 is attached to the holder 18 with its lens facing downward.

17 is a strobe, which is placed in holder 1 with the light emitting window facing downward.
8 is number one.

Sensor pairs 13 and 14 detect the position of the fish 5-1, and through a control circuit (not shown) give instructions to the strobe 17 to emit light and to the television camera 16 to take pictures.

Since the strobe light emission time is as short as several tens of microseconds, even if the fish 5-1 is running inside the tray 1), the posture of the fish can be captured without image blur t,b, ::,=i
<ras・ Recognition processing unit (predecoy,
Patent application No. 57-229480.57-104745.57
-267380) uses the video output of the television camera 16 to perform dorsal/ventral discrimination, head/tail discrimination.

108 is a spike drum, 108-1 is a pin.

109 is a weight roller, 109-1 is a shaft, and 1) 0 is a plate. 108,108-1.109゜109-1
The role of is to temporarily stop the fish 5-1 running in the tray 1) at the weight roller 109, and after waiting time has passed, move the fish 5-1 again and take in the video output of 16 to examine the back, abdomen, and head.・It takes some time (hereinafter referred to as recognition time) to judge the tail. Furthermore, as shown in Japanese Patent Application No. 57-229480, it takes some time (hereinafter referred to as setting time) to set the selection gates in a specified direction based on the judgment result of the recognition process. Therefore, waiting time is required.

108 and 108-1.109, 109i, 109-2
．． 'llO settings are 8.8-1.9.9-1.9-2
．． 10, but the distance between the sensor pair 13.14 and the weight roller 109 is shorter than the length of the fish body, that is, when the weight roller 109 is clogged with a fish, the clogged fish blocks the light beam. Set the interval.

The fish 5-1 running in the tray 1) and crossing the center pair 13.14 is caught between the weight roller 109 and the catch plate 1) 0 and stops once. The fish 5-1 remains stationary until the spike drum 108 rotates and the pin 108-1 hooks the cod of the fish 5-1, allowing a waiting time.

That is, the fish 5-1 is intermittently taken out from the tray 1).

In this embodiment, a spike drum 8 and a spike drum 10 are used.
8 have the same diameter, are driven at the same rotation period, and pin 8-1
and the phase angle of pin 108-1 are appropriately set to obtain the required waiting time.

Figure 2 shows the controls for the operation of the shutter 6 and tray 1).
Removes chattering components contained in the electrical output of the light receiving sensor.

82 and 83 are counting circuits having a counter and two input terminals. When a pulse of 1 (IliI is added to one of the input terminals 82 ■ (■ in 83, same order hereafter), the counter becomes +
Addition of 1 is performed, and the other input terminal, in this figure, @ < (i
When one pulse is added to :)>, the counter subtracts -1.

The counting circuit calculates ■ (■) in the counter when an appropriate nosorse number set in advance is No (N'o).
When the difference between the pulse train applied to the terminal and the pulse train applied to the ■ (■) terminal becomes more than No (No'), an output is output to the terminal ◎ (O). For example, if the difference between the pulse train of the Kuno terminal and the pulse train of the ■ (■) terminal becomes more than No (No'), @<(5
The terminal becomes state ``1'' and remains as it is.The ■(■) terminal of the counting circuit is a clear terminal, and when the signal from the ■(■) terminal G is applied, the contents of the counter are forcibly changed. becomes zero, and at the same time the ◎ (◎) terminal also returns to the “0” state.

In the present invention, the logic state is "1".

The following will explain the relationship between "0", the high signal level (H'), and the low signal level (L'') as follows.

Then, only when the input terminal ■ is “H”, “1” is sent to the output terminal O.
” is output.

85, 86, and 87 are matching circuits, and the input terminal ■ is "1" and the input terminal (input terminal in 86) is "1".
7, H" is 1" or lower (same order) and other input terminals
When is “L” (ω is “H”) (■ is “L”), °bi (■ is “1”) is sent to the output terminal ■.

Reference numeral 88 denotes a driver circuit, which supplies a driving power source of AC 100 V to the air valves 51 and 53 when the input terminal (2) is "1".

Reference numeral 89 denotes a driver circuit, which supplies a driving power supply AC 100 V to the indicator light 54 when the input terminal (2) is at 1" to turn on the indicator light.

The operation will be explained using the configurations shown in FIGS. 1 and 2 described above.

1) In normal operation, the shutter 6 is normally set in an open state, and when the vibration trough 1 is vibrated, the fish 5 moves toward the weight roller 9 so as to be pushed toward it. The spike drum 8 rotates at a speed of about 60 revolutions per minute, and the weight roller 9 and pin 8
With the cooperation of -1, about one fish per second can be caught in the tray1).
send to.

In synchronization with the rotation of the spike drum 8, the rotary encoder 52 sends out an electric pulse when the pin 8-1 is almost directly above it.

The fish 5-1 fed into the tray 1) is accelerated by the feather brush 12 and advances, blocking the light beam.

Therefore, during normal operation, when the rotary encoder 52 sends out one electric pulse, one electric pulse is sent out from the light receiving sensor 1a after a certain amount of time has elapsed.

108.109.1) Fish 5 by means of intermittent feeding consisting of 0
-1 is taken out from the tray 1), so the light beam reaches the light receiving sensor 14 from the light emitting sensor 13 again. Therefore, as one fish passes by, the electric path output of the light receiving sensor 14 changes from "H" to "L" to "H". If the counters of the counting circuits 82 and 83 have previously entered NO or a value smaller than NO, such as zero, they maintain that value.

The operation at the time of boiling down will be explained below.

2) - In the case of fish clogging in the means of tail separation feeding, as mentioned above, there are two types of fish that live in nature: long and short, large and small.
Some fish are not fed into the tray 1) by the pin 8-1 of the spike drum 8 and get stuck at the weight roller 9. If this is left unchecked, the equipment will be running dry, so it is necessary to immediately display the clog and let the operator know.

If the weight roller 9 is clogged with fish, the fish will not move to the tray 1.
), the light beam is not blocked by the fish, and the output of the light receiving sensor 14 remains at "H".

Therefore, no electric pulse is applied to the ■ terminal of the counting circuit 83, and no subtraction is performed.

On the other hand, since the spike drum 8 rotates at a constant rotational speed, each time the spike drum 8 rotates once, an electric pulse is applied from the rotary encoder 52 to the six registers of the counting circuit 83 and added to the counter.

Therefore, since the counting circuit 83 only performs addition without subtraction, if the spike drum 8 continues to rotate, the cumulative value in the counter will be equal to the value N preset in the counting circuit 83.
'o will be exceeded. When NO is exceeded, the counting circuit 83
Since the output terminal °C remains in the state of "B, and the electrical output of the light receiving sensor 14 remains as I]", - several circuits 86
The driver circuit 89 turns on the indicator light 54 to indicate that the weight roller 9 is clogged with fish.

In the embodiments shown in FIGS. 1 and 2, an indicator light is displayed, but a circuit equivalent to the driver circuit 89 is arranged in parallel to enable (1) to sound a buzzer or (2) to control the eccentric crank 3 of the vibration trough 1. Needless to say, the present invention can be applied to automatically cutting off and stopping a drive source (not shown) or (3) automatically cutting off and stopping a drive source (not shown) of the spike drum 8.

4, that is, the clearing operation of the counting circuit 83 will be described.

By lighting the indicator light 54, either the fish stuck in the F troller 9 is removed and the fish 1 is sent to the tray 1), or the fish that is stuck is pushed by the following fish and removed. When the tilt changes and the light beam is sent to the tray 1) by the bin 8-1 and blocked, the input terminal of the - number circuit 86 (i <"L" becomes, so ■ becomes "0" and the indicator light 5
4 goes out.

In addition, the input terminal [present] of the -number circuit 87 remains '1', and as for ■, the sensor output 14 is "'L" as described above, so the output ■ of the -number circuit 87 becomes "1". The counter contents of the counting circuit 83 are forcibly set to zero. Therefore, the output terminal @ of the counting circuit 83 becomes "0" and is cleared.

3) When the intermittent feeding means 6 is clogged with fish If the weight roller 109 is clogged with fish, the weight roller 9. Each time the spike drum 8 rotates, fish are fed into the tray 1) from the single fish separating and feeding means consisting of the spike drum 8, so that fish accumulate in the tray 1) and may even overflow from the tray 1). It turns out. Therefore, fish are blocked from entering tray 1), and tray 1)
It is necessary to remove accumulated fish.

When the weight roller 109 is clogged with fish, the clogged fish continues to block the light beam, so the output of the light receiving sensor 14 remains at L". Therefore, the input terminal (2) of the counting circuit 82 receives an electric pulse. is not entered, and the counter of the counting circuit does not perform subtraction.

On the other hand, since the spike drum 8 rotates at a constant number of revolutions, at the same time as feeding the fish into the tray 1) each time it rotates, an electric pulse is applied from the rotary encoder 52 to the ■ terminal of the counting circuit 82, and is added up by the counter. Ru. Therefore, since the counting circuit 82 performs only addition without subtraction, if the spike drum 8 continues to rotate, the cumulative value in the counter will exceed the value No. set in advance in the counting circuit 82. When NO is exceeded, the output terminal @ of the counting circuit 82 is held in the state of "'1", and the output of the light receiving sensor 14 remains "L", so 1, - number circuit 8
5's input terminal ■ becomes "L" and the output terminal becomes "'1"
Then, via the driver circuit 88, the air valve 51
．． 53 works to switch the flow direction of high-pressure air. When the air valves 51 and 53 change the flow direction of the high pressure air, the direction of the high pressure air flowing into the air cylinder 7 and the air cylinder 15 changes, and the shaft 7-1 of the air cylinder 7 contracts, and the shutter 6 cools the fish passage. . At the same time, air cylinder 1
The shaft 15-1 of the tray 1) is extended, and the tray 1) is rotated clockwise and held in a downward facing position.

When tray 1) is turned downward, the fish stored in tray 1) will move along the slope of tray 1), and
) to be excluded outside. As mentioned above, since the shutter 6 is closed, no new fish enters the tray, and the tray 1) becomes empty.

When the tray 1) is empty, the light beam is directed to the light projection sensor 1.
3 reaches the light receiving sensor 14, so the light receiving sensor 14
The output of the -number circuit 85 becomes "H". Therefore, the @ terminal of the -number circuit 85 is in the "1" state, but since the first child becomes "H", the output terminal ■ of the -number circuit 85 becomes "0P". Become. Since the input terminal (2) of the driver 88 becomes "0", the driver 88 switches the air valves 51 and 53 in the return direction, so the shack 6 opens and the tray II returns to a substantially horizontal position.

By the way, the output terminal O of the counting circuit 82 is still held at "'1".Therefore, the input terminal (■) of the comparison circuit 84 is in the state of "'1", but the ■ terminal becomes "L". Therefore, the output terminal (2) becomes "'1" and the counter of the counting circuit 82 is forced to zero and is cleared.

(G) Effects of the Invention According to the present invention, a fish body image input device can automatically detect a fish blockage, display a fish blockage,
Since it can be automatically removed, it is possible not only to improve the operation of the device, but also to facilitate the operation of the device, and at the same time to contribute to labor saving of the device.
