Abstract
Description
[Technical Field]
[0001] The present invention relates to a fish treatment device in which a fluid is forced into the vascular system of a fish through a tubular device inserted into said vascular system. [Background technology]
[0002] Conventionally, some fish processing devices as described above include a pressure pump that applies pressure to a liquid in a container so that the liquid is forced into the vascular system of a fish through a tubular device (a syringe needle). To bleed a fish using this fish processing device, for example, an operator inserts the tubular device into the vascular system of the fish and then activates the pressure pump to force the bleeding liquid into the vascular system of the fish and expel the fish's blood from the body. While the bleeding liquid is being injected, the operator determines whether a sufficient amount of bleeding liquid has been injected by observing the color of the fish's gills and the color of the liquid flowing out of the fish. When the operator determines that a sufficient amount of bleeding liquid has been injected, the operator stops the operation of the pressure pump to terminate the bleeding. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2023-044743 Summary of the Invention [Problem to be solved by the invention]
[0004] However, if the amount of bleeding liquid injected during the bleeding of fish is too small, the effects of bleeding, such as preventing putrefaction, cannot be fully achieved, and conversely, if the amount of bleeding liquid injected is too large, the amount of liquid consumed increases and the time required for bleeding increases, resulting in a decrease in productivity. Furthermore, sufficient experience and intuition are required to accurately judge whether the appropriate amount of bleeding liquid has been injected, and since the size of fish varies widely, workers who perform bleeding properly must be skilled.
[0005] The present invention has been made in consideration of the above-mentioned problems of the prior art. The object of the present invention is to provide a fish processing device that enables even an unskilled person to pressurize an appropriate amount of fluid required for processing fish, such as bleeding, into the vascular system of the fish.
[0006] According to a first aspect of the present invention, a fish processing device pressurizes a fluid into the vascular system of a fish through a tubular instrument inserted into the vascular system, and comprises: a valve provided in a fluid supply line connected to the tubular instrument; a control device that opens and closes the valve so that the amount of fluid injected is the required amount; and a weighing device that measures the size of the fish, wherein the control device comprises a control circuit configured to set the duration of the opening operation of the valve equal to a delay time set in a timer, and a delay time input unit that inputs the delay time to the timer, and the delay time input unit comprises a function memory unit that stores an approximation function in which the size of the fish is an independent variable and the required time for injecting the fluid into the fish is a dependent variable, and the required time for injecting the fluid into the fish can be calculated as the delay time based on the measurement value of the size of the fish obtained by the weighing device and the approximation function.
[0007] With this configuration, it is possible to inject an appropriate amount of fluid into the vascular system of the fish by pressure, eliminating the need for an operator to stop injecting the fluid, and even an unskilled person can efficiently and accurately process the fish, such as by bleeding it. In addition, it is economical because the fluid is not consumed unnecessarily.
[0008] According to a second aspect of the present invention, a fish processing device for injecting fluids into the vascular system of a fish through a tubular instrument inserted into the vascular system includes a plurality of fluid supply paths branching from a single pipe connected to the tubular instrument for individually supplying a plurality of fluids different in type or composition from each other, a plurality of valves provided in each of the plurality of fluid supply paths, a measuring device for measuring the size of the fish, and a control device for selecting two fluids from the plurality of fluids based on the fish size measured by the measuring device and individually operating the plurality of valves so that the amount of each fluid injected becomes a required amount in sequence, and when two fluids from the plurality of fluids are selected, the control device operates a valve provided in the supply path for one of the two fluids. and a control circuit configured to operate a valve provided in a supply line for another fluid after operating the selected valve, and to set the duration of each open operation of the valves in the supply lines for the two selected fluids equal to the delay times set in the timers for each of the two fluids; and a delay time input unit for each of the plurality of fluids that inputs each delay time to the timers for each of the plurality of fluids provided in the control circuit, wherein each of the delay time input units for each of the plurality of fluids has a function memory unit that stores an approximation function with the size of the fish as an independent variable and the required time for injecting the fluid into the fish as a dependent variable, and can be configured to calculate the required time for injecting the fluid into the fish as the delay time based on the measurement value of the size of the fish obtained by the weighing device and the approximation function.
[0009] With the above-mentioned configuration, multiple fluids of different types or components can be automatically injected sequentially in appropriate amounts into the vascular system of a fish, and even when multiple fluids are being injected, after the first fluid has been injected, there is no need for the operator to start and stop the fluid injection, and there is no need to reinsert the tubular instrument each time a multiple fluid of different types or components is injected, so even an unskilled person can accurately and efficiently perform processes such as bleeding the fish.In addition, there is no unnecessary consumption of fluids, making it economical.
[0010] According to the fish processing device of the third aspect of the present invention, the approximation function can be configured to be generated based on injection data including the measured values of the size of each fish when the fluid was injected in the past to ensure an appropriate amount of fluid was injected into a large number of fish, as well as the measured value of the actual injection time.
[0011] With the above configuration, if an expert operates the fish processing device to obtain press-in data, an approximation function can be obtained relatively easily based on the press-in data.
[0012] According to the receiving plate attachment device of the fourth aspect of the present invention, the device can be configured to include a trained model that generates training data by machine learning, including information on the condition of the fish before and after processing, information on the processing device, information on the person who performed the processing, and information on the climate, and outputs output data that is data on a correction time that corrects the delay time, based on input data that includes information on the condition of the fish before processing, information on the processing device, information on the person who performed the processing, and information on the climate.
[0013] With the above configuration, the fish processing device is equipped with a trained model, which makes it possible to output a correction time that takes into account, for example, individual differences between fish and processing devices, differences in the person performing the processing (operating habits), differences in climate, etc., which are difficult to judge mechanically, and reflect this in the delay time.
[0014] According to a fifth aspect of the present invention, the control circuit comprises an operation switching operation unit capable of appropriately switching between an automatic stop operation in which the valve is automatically closed and a manual stop operation in which the valve is manually closed, a start operation unit capable of issuing a start signal during the automatic stop operation, a press-in start operation unit capable of issuing a start signal during the manual stop operation, and a press-in stop operation unit capable of issuing a stop signal during the manual stop operation, and the control circuit is configured so that during the automatic stop operation, the valve is opened by the start signal from the start operation unit, and the duration of the open operation of the valve is equal to the delay time set in a timer. and a delay time input unit configured to receive a start signal from the injection start operation unit to command the valve to open, and to receive a stop signal from the injection stop operation unit to command the valve to open, and the delay time input unit can further be configured to include an injection data creation unit that measures, during the manual stop operation, the elapsed time from receiving the start signal from the injection start operation unit to receiving the stop signal from the injection stop operation unit as an actual injection time, and creates and stores injection data including the measured value of the actual injection time and the measurement value of the fish size obtained by the weighing device, and a function generation unit that generates the approximation function based on the large number of injection data stored in the injection data creation unit and stores the approximation function in the function memory unit.
[0015] With the above configuration, an experienced person can operate the fish processing device to inject fluid, thereby obtaining injection data within the fish processing device, and an approximate function can be generated within the fish processing device based on the injection data, which is convenient.
[0016] According to the fish processing device of the sixth aspect of the present invention, the delay time input unit can be configured to calculate the required delay time based on the species of fish to be processed and an approximation function for each fish species generated according to the fish species.
[0017] With this configuration, even when different kinds of fish are supplied to the fish processing position, an appropriate amount of fluid can be pressurized according to the fish kind.
[0018] According to a seventh aspect of the present invention, there is provided a fish processing device for injecting a fluid used for processing fish into the vascular system of a fish through a tubular instrument inserted into the vascular system, the device comprising: a valve provided in a supply path for the fluid connected to the tubular instrument; a control device for opening and closing the valve so that the amount of fluid injected is a required amount; and a measuring device for measuring the size of the fish, the control device comprising: a required injection amount setting unit for setting a required injection amount of the fluid; an integrating flow meter for measuring an integrated flow rate of the fluid passing through the supply path; and a required injection amount calculation unit for calculating the required injection amount and the integrating flow meter. the required injection amount setting unit is provided with a function memory unit that stores an approximation function in which the measurement value of the fish size is an independent variable and the required injection amount of the fluid for the fish is a dependent variable, and is configured to calculate the required injection amount of the fluid for the fish based on the measurement value of the fish size obtained by the measuring device and the approximation function.

[0021] The following describes embodiments of the present invention with reference to the drawings. However, the embodiments described below are merely examples of fish processing devices embodying the technical concepts of the present invention, and the present invention is not limited to these. Furthermore, this specification in no way specifies the components set forth in the claims as components of the embodiments. The dimensions, materials, shapes, and relative locations of components described in the embodiments are not intended to limit the scope of the present invention, and are merely illustrative unless otherwise specified. The size and relative positions of components shown in the drawings may be exaggerated for clarity. Furthermore, in the following description, identical names and symbols indicate identical or similar components, and detailed descriptions will be omitted as appropriate. Furthermore, the elements constituting the present invention may be configured with the same components, with one component serving multiple functions, or the functions of one component may be shared among multiple components. (First embodiment)
[0022] As shown in Figure 1, a fish processing device 1 according to a first embodiment of the present invention pressurizes a fluid F into the vascular system of a fish through a tubular instrument 2 inserted into the vascular system, and is equipped with a valve 4 provided in a supply path 3 for the fluid F connected to the tubular instrument 2, a control device 5 that operates the valve 4 so that the amount of fluid F pressed in is the required amount, and a weighing device 6 that measures the size of the fish.
[0023] According to this embodiment, the fish processing involves bleeding one type of fish by forcing a bleeding fluid F into the vascular system of the fish to expel the blood from the body. The bleeding fluid F is saline containing fine bubbles. Depending on the need, fresh water, simple saline, freshness-preserving gas, or the like may be used as the bleeding fluid F. The size of the fish is determined by its weight.
[0024] The tubular device 2 has a flexible conduit 2a made of a flexible tube, and the rear end of this flexible conduit 2a is connected to the front end of the supply channel 3. The supply channel 3 may be a tube or a block having a through hole for the fluid F formed therein.
[0025] Valve 4 is a solenoid valve that is normally closed to prevent the passage of fluid F, and when its solenoid SV is excited, it opens to allow the passage of fluid F. When valve 4 is opened, fluid F at a predetermined pressure from a supply source 7 of fluid F can be supplied to supply path 3. If necessary, a pilot valve that receives a pressure signal from fluid F to drive a valve element may be used instead of the solenoid valve.
[0026] The fluid F supply source 7 includes a pump 7a that delivers fluid F from a container 7b. The fluid F delivered from the pump 7a passes through a pressure reducing valve 7c and an accumulator 7d that stores fluid F to suppress pressure fluctuations, then passes through a pressure regulating valve 7e and a delivery pipeline 7f that extends to multiple processing locations, and is then supplied to valve 4 via a pipeline 7g that branches off from delivery pipeline 7f. Pump 7a stops operating when it detects an upper limit of the pressure set by pressure switch 7h, and stops operating again when it detects a lower limit. The pressure of the fluid F supplied to valve 4 is regulated to a predetermined value by pressure regulating valve 7e. (Measuring device)
[0027] Weighing device 6 is a weighing scale that measures the weight of fish and is installed near the fish processing location. When a fish is placed on the weighing pan of weighing device 6, a load cell is activated to measure the weight of the fish, and immediately thereafter, for a fixed short period of time, weighing signal Sw including the measured weight value Wm is output to control device 5. (Control device)
[0028] The control device 5 includes a control circuit 9 configured to set the duration of the opening operation of the valve 4 equal to the delay time set in the timer T, and a delay time input unit 10 that inputs the delay time into the timer T. (Control circuit)
[0029] As shown in Figures 2 and 3, the control circuit 9 includes switch SS0, pushbutton switches PB1, PB2, PB3, and PB4, as well as electromagnetic relays R0 and R1, all located on the control panel 8. Figure 2 is a sequence circuit diagram based primarily on the symbols specified in JSIA 118. The operation switch SS0 is a control unit that can switch between automatic stop operation, which automatically closes valve 4 to ensure the required amount of fluid F is injected into the fish's vascular system, and manual stop operation, which manually closes valve 4. Switching to manual stop operation with the operation switch SS0 energizes the electromagnetic coil of electromagnetic relay R0, closing its contact a. The start pushbutton switch PB1 is a control unit that issues a start signal during automatic stop operation. The pushbutton switch PB2 is used to emergency stop the injection of fluid F during automatic stop operation. Push button switch PB3 is a press-fit start operation unit that can output a start signal during manual stop operation. Push button switch PB4 is a press-fit stop operation unit that can output a stop signal during manual stop operation. The a-contact is a contact that opens when the electromagnetic coil of the electromagnetic relay is not excited and closes when the electromagnetic coil is excited, while the b-contact is a contact that closes when the electromagnetic coil of the electromagnetic relay is not excited and opens when the electromagnetic coil is excited.
[0030] During automatic stop operation, when the start push button switch PB1 is pressed, the electromagnetic coil of the electromagnetic relay R1 is excited, its contact a closes, and the excited state of the electromagnetic coil is self-maintained. An excitation current flows through the contact a to the solenoid SV of the valve 4, opening the valve 4. At the same time, the timer T begins measuring the elapsed time. When the momentarily measured value tm of the elapsed time measured by the timer T reaches the set delay time Ts, the contact b of the timer T opens, stopping the excitation of the electromagnetic coil of the electromagnetic relay R1 and opening the contact a, cutting off the excitation current to the solenoid SV of the valve 4, closing the valve 4. Therefore, the control circuit 9 is configured so that the duration of the open operation of the valve 4 during automatic stop operation is equal to the delay time set in the timer T.
[0031] When the operation selector switch SS0 is operated to switch to manual stop operation, pressing the press-fit start push button switch PB3 sends out a start signal just as in automatic stop operation, exciting the electromagnetic coil of the electromagnetic relay R1, closing its a-contact and self-maintaining the excited state of the electromagnetic coil, and an excitation current flows through the a-contact to the solenoid SV of valve 4, opening valve 4. When the press-fit stop push button switch PB4 is pressed, its b-contact opens, stopping the excitation of the electromagnetic coil of the electromagnetic relay R1, opening its a-contact, cutting off the excitation current to the solenoid SV of valve 4, and closing valve 4. (Computer input / output unit)
[0032] The delay time input unit 10 and timer T are configured using a computer C shown in Figure 4. The weighing device 6 is connected to the input interface unit Ci of the computer C via lead wires, and is further connected to the a-contacts of electromagnetic relays R0 and R1 of the control circuit 9. The output interface unit Co is connected to an electromagnetic relay Tr. The electromagnetic coil of this electromagnetic relay Tr is excited by an output signal that is output when the set time of the timer T has elapsed. The b-contact of the timer T in Figure 2 is the b-contact of this electromagnetic relay Tr. (Delay time input section)
[0033] As shown in Figure 5, the delay time input unit 10 includes a fish size memory unit 11 that stores the fish size measurement value Wm obtained by the weighing device 6, a function memory unit 12 that stores an approximation function ft with the fish size w as the independent variable and the required injection time t of fluid F into the fish as the dependent variable, a required delay time calculation unit 13 that calculates the required injection time of fluid F into the fish as a delay time Ts based on the approximation function ft stored in the function memory unit 12 and the fish size measurement value Wm stored in the fish size memory unit 11, and an output unit 14 that sets the delay time Ts calculated by the required delay time calculation unit 13 in a timer T. (timer)
[0034] The timer T measures the elapsed time since receiving the start signal by counting pulse signals from a clock generator using an elapsed time measuring section 15, and compares the measured value tm of the elapsed time measured from moment to moment with the delay time Ts set in the delay time setting section 16 using a comparing section 17. When the measured elapsed time tm reaches the delay time Ts set in the delay time setting section 16, the delay time setting section 16 outputs an output signal from its output section 18. When the delay time setting section 16 receives the output signal of the delay time Ts from the output section 14 of the delay time input section 10, it can store the delay time Ts. (approximation function)
[0035] The approximation function ft stored in the function memory unit 12 is generated based on injection data Dm, which includes the measurement values Wm of the size of each fish and the actual injection time Tm, when the amount of fluid F injected into a large number of fish in the past was appropriate.
[0036] Figure 6 shows an example of injection data Dm. This injection data Dm consists of a collection of numerous individual data D0m, each of which includes common parameters for fish processing: fish species, fluid F pressure, and fluid F composition; and for each fish, a fish number, a fish weight measurement Wm, and the actual measurement of the time required to inject fluid F into the fish (i.e., the actual injection time Tm). The injection data Dm is obtained by an expert who can determine whether the amount of fluid F injected is appropriate. Simple regression analysis is used to generate the approximate function ft from the obtained injection data Dm. When a scatter diagram is created based on the injection data Dm, it can be empirically determined that there is no significant error when the relationship between the fish weight w and the injection time t of fluid F is expressed as a linear function t = αw + β. Therefore, the approximate function ft is expressed as a regression equation of t = αw + β, with the coefficients α and β calculated using the least squares method based on the injection data Dm. Therefore, the function storage unit 12 stores t=αw+β as the approximate function ft.
[0037] 5, the approximate function ft can be input to the function storage unit 12 by a function input unit 19 provided in the delay time input unit 10 when the contact a of the electromagnetic relay R1 shown in FIG. 4 is open, that is, when the injection of the fluid F is stopped. The function input unit 19 can read the approximate function ft recorded in advance in a storage medium using an input device such as a keyboard (not shown), and store it in the function storage unit 12. (Fish size memory section)
[0038] The fish size memory unit 11 stores the fish size measurement value Wm when it receives the weighing signal Sw from the weighing device 6, and thereafter updates the stored value every time it receives a weighing completion signal Sw. (Delay time input section operation)
[0039] When the a-contact of the electromagnetic relay R1 closes, the delay time input unit 10 calculates the required press-in time Ts based on the fish size measurement value Wm from the fish size memory unit 11 and the approximation function ft stored in the function memory unit 12, and outputs the calculated required press-in time Ts from the output unit 14 to the delay time setting unit 16 of the timer T as the delay time setting value Ts. Upon receiving the delay time setting value Ts, the timer T immediately begins measuring the elapsed time using the elapsed time measurement unit 15. The output signal from the output unit 18 of the timer T excites the electromagnetic coil of the electromagnetic relay Tr shown in FIG. 4 and opens its b-contact (the b-contact of the timer T shown in FIG. 2). This stops the excitation of the electromagnetic coil of the electromagnetic relay R1, and resets the delay time set in the timer T. The timer T then stops until the next a-contact of the electromagnetic relay R1 closes. (Function generation function)
[0040] Furthermore, in order to give the delay time input unit 10 itself an approximate function generation function, it is equipped with a press-in time measurement unit 21 that measures, during manual stop operation, the elapsed time from receiving a start signal from push button switch PB3 to receiving a stop signal from push button switch PB4, that is, the time during which the electromagnetic coil of electromagnetic relay R1 is excited and the a-contact is closed, as the actual press-in time; an actual press-in time memory unit 22 that stores the actual press-in time Tm measured by the press-in time measurement unit 21; a press-in data memory unit 23 that, during manual stop operation, receives the fish size measurement value Wm from the fish size memory unit 11 for each fish processed and the actual press-in time Tm from the actual press-in time memory unit 22, and creates and stores press-in data Dm including the fish size measurement value Wm and the actual press-in time Tm; and a function generation unit 24 that generates an approximate function ft based on the large number of press-in data Dm stored in this press-in data memory unit 23 and stores it in the function memory unit 12. (operation panel) The control panel 8 shown in Fig. 3 further includes selector switches SS1, SS2, and SS3, which can be operated when the injection of fluid F is stopped, push button switches PB5 and PB6, a weight display unit 6a that displays the weight of the fish measured by the weighing device 6, and a fish size setting unit 6b for manually inputting the weight of the fish, all of which are connected via lead wires to the input interface unit Ci of the computer C shown in Fig. 4. The fish size setting unit 6b is, for example, a variable resistor with a knob. The delay time input unit 10 shown in Figure 5 further includes a function input unit 19 for inputting and storing an approximate function ft generated in advance externally into the function memory unit 12, a press-in data input unit 25 for inputting and storing press-in data Dm created in advance externally into the press-in data memory unit 23, and a measurement value input unit 26 for inputting the fish weight setting value set by the fish size setting unit 6b into the fish size memory unit 11 as a measurement value of the fish weight.
[0041] The selector switch SS1 is used to select whether the approximation function ft is input to the function memory unit 12 from the internal function generator 24 or from the function input unit 19. The push button switch PB5 is used to command the function generator 24 to generate a function when the approximation function ft is input from the internal function generator 24 to the function memory unit 12. The selector switch SS2 is used to select whether the input of the press-fit data Dm to the press-fit data memory unit 23 is performed automatically from the fish size memory unit 11 and the measured press-fit time memory unit 22, or manually from the press-fit data input unit 25. The selector switch SS3 is used to select whether the input of the fish size measurement value Wm to the fish size memory unit 11 is performed manually from the measurement value input unit 26 or automatically from the weighing device 6. When manually inputting the fish size measurement value Wm, the user can determine the fish weight measurement value Wm by looking at the display on the measurement value display section 6a of the operation panel 8, then align the knob of the measurement value input section 26 with the scale corresponding to the determined weight, and press the push button switch PB6 to input the fish size measurement value Wm into the fish size memory section 11. (Press-fit time measurement unit)
[0042] In Figure 5, the pressing time measurement unit 21 is configured in the same way as the elapsed time measurement unit 15 of the timer T, and when the pressing data Dm is automatically input into the pressing data memory unit 23 from the fish size memory unit 11 and the measured pressing time memory unit 22, measurement of the elapsed time starts when the a contact of the electromagnetic relay R1 closes, and stops when the a contact of the electromagnetic relay R1 opens, and stores the measured value of the elapsed time as the measured pressing time Tm in the measured pressing time leg 22. (Press-fit data storage unit)
[0043] In order to create the injection data Dm as shown in Figure 6, the injection data memory unit 23 has a memory unit that stores a large number of unit injection data D0m for a large number of fish, each unit consisting of an input number k indicating the order in which the unit injection data D0m for each fish was input, a measured value Wm of the fish weight, and an actual injection time Tm, and a memory unit that respectively stores the type of fish, i.e., fish species, pressure of fluid F, and components of fluid F, and the fish species, pressure of fluid F, components of fluid F, etc. are input into each memory unit in advance.
[0044] After the start of pressing, when the a contact of the electromagnetic relay R1 opens and a predetermined short time has elapsed, the pressing data memory unit 23 adds 1 to the largest input number among the input numbers stored in the pressing data memory unit 23 to create a new input number, and creates unit pressing data D0m from this input number, the measured value Wm of the fish size stored in the fish size memory unit 11, and the actual pressing time Tm stored in the actual pressing time memory unit 22, and stores it in the new individual data memory unit. (Function generator 24)
[0045] The function generating unit 24 stores an equation for calculating the coefficients α and β of the approximate function ft (t=αw+β) by the least squares method based on the press-fit data Dm stored in the press-fit data storage unit 23. When the press-fit data Dm is press-fit data A shown in Fig. 6, the coefficients α and β can be calculated by the following equations 1 and 2.

[0046] To process fish using the fish processing device 1 configured as described above, first, the injection data Dm is acquired, then an approximation function ft is generated based on the injection data Dm, and the approximation function ft is input and stored in the function memory unit 12. The fish processing method using the fish processing device 1 comprises an insertion process, a weighing process, and a manual injection process or an automatic injection process. In the manual injection process, the operator manually starts and stops the injection of the fluid F and acquires the injection data Dm. In the automatic injection process, after the approximation function ft is stored in the function memory unit 12, the operator manually starts the injection of the fluid F, and the injection of the fluid F is stopped automatically.
[0047] The injection data Dm may be data that has already been acquired outside the fish processing device 1, but since the fish processing device 1 is designed to acquire injection data Dm internally, we will explain how to process fish using this function.
[0048] To obtain the injection data Dm inside this fish processing device 1, the selector switch SS0 is operated in advance to set the device to manual stop operation. The pressure of the fluid F is also adjusted to a predetermined value. Furthermore, the fish processing device 1 is operated by an experienced person who can accurately judge whether the injection amount of the fluid F is appropriate by observing the color of the gills and the color of the discharged fluid F.
[0049] In the insertion process, the operator inserts the tubular instrument 2 into the vascular system of the fish that has been killed alive. In the next weighing process, the size of the fish is measured. To do this, the fish is placed on the weighing tray of the weighing device 6 with the tubular instrument 2 inserted into its vascular system, and the size of the fish, in this embodiment the weight w of the fish, is measured. Immediately after the weighing by the weighing device 6 is completed, the weighing device 6 outputs a weighing signal Sw including the measured value Wm of the size of the fish.
[0050] In the manual injection process, first, the valve 4 is opened to start injecting the fluid F. To do this, the operator presses the push button switch PB3, which energizes the solenoid SV of the valve 4, opening the valve 4 and injecting the fluid F into the vascular system of the fish through the tubular device 2.
[0051] Next, the worker continues to monitor the condition of the fish, etc., and when he determines that the amount of fluid F injected has reached an appropriate value, he stops injecting the fluid F. To do this, the worker presses the push button switch PB4. This stops the excitation of the solenoid SV of the valve 4, closes the valve 4, and stops the injection of the fluid F. The worker then removes the tubular device 2 from the vascular system of the fish and sends the fish to the next process. Then, when a large number of fish are processed sequentially using this processing method, the injection data Dm is stored and accumulated in the injection data memory unit 23 each time. (Input of approximate function to function memory)
[0052] When a large amount of press-fit data Dm is collected to generate an accurate approximation function ft, the operator causes the function generation unit 24 to generate the approximation function ft. To do this, the operator presses the push button switch PB5 for starting automatic function input, with the selector switch SS1 selected to input the approximation function ft to the function storage unit 12 from the internal function generation unit 24. This causes the function generation unit 24 to calculate the coefficients α and β of the approximation function ft based on the press-fit data Dm in the press-fit data storage unit 23, and inputs and stores them in the function storage unit 12.
[0053] Furthermore, when the operator selects with the selector switch SS1 to input the approximation function ft to the function memory unit 12 from the function input unit 19 and then presses the push button switch PB5 for starting automatic function input, the externally generated approximation function ft is input to the function memory unit 12 via the function input unit 19 and stored therein.
[0054] To process fish after storing the approximate function ft in the function memory unit 12, in the automatic injection process, the operator switches the operation mode to automatic stop operation using the selector switch SS0, and then presses the push button switch PB1 to start injection of the fluid F. Then, when the required injection time has elapsed, the injection of the fluid F automatically stops. Second Embodiment
[0055] Next, a second embodiment of the present invention will be described with reference to FIGS.
[0056] As shown in Figure 7, the processing device 1 of the second embodiment of the present invention selectively pressurizes fluids F1, F2, and F3, each of which is different in type or contains different components, into the vascular system of a fish via a tubular instrument 2 inserted into the vascular system of the fish.
[0057] This fish processing device 1 includes supply paths 31, 32, and 33 for fluids F1, F2, and F3 branching from a single supply path 3 connected to a tubular device 2 via a flexible conduit 2a, valves 41, 42, and 43 provided on the supply paths 31, 32, and 33 for fluids F1, F2, and F3, a control device 5 for individually operating valves 41 and 42 or valves 41 and 43 to select only fluid F1 from the three fluids F1, F2, and F3 and inject a required amount of fluid F1, or to select two of the three fluids F1, F2, and F3 and inject the selected fluids F1 and F2 or F1 and F3 sequentially to the required amounts, and a measuring device 6 for measuring the size of fish. The fish processing device 1 also includes a fish species detection device 27 for detecting in advance the species of fish sent to a processing position by the fish processing device 1. (Fish species detection device)
[0058] The fish species detection device 27 uses a camera to capture an image of a fish placed on the weighing device 6 or a workbench, etc., and automatically determines the fish species by performing AI image recognition on the captured image.It is configured to output a fish species detection completion signal Sk, which includes an identification code KF corresponding to the fish species, to the control device 5 for a certain short period of time immediately after determining the fish species. (Control device)
[0059] The valves 41, 42, and 43 are each an electromagnetic valve, and the control device 5 includes a control circuit 9 and delay time input units 101, 102, and 103 for fluids F1, F2, and F3, which input individual delay times to timers T1, T2, and T3 for fluids F1, F2, and F3 provided in the control circuit 9.
[0060] In this embodiment, fluid F1 is a liquid for draining blood, such as physiological saline containing fine bubbles, fluid F2 is a liquid for modifying or improving the quality of fish meat, such as an aqueous solution of a flavor extracted from citrus fruits such as Ainan Gold (a registered trademark of the Ainan Town Chamber of Commerce and Industry), and fluid F3 is a gas for preserving the freshness of fish, such as a mixture of nitrogen and hydrogen. Furthermore, supply paths 31, 32, and 33 have check valves 3a near their respective ends to prevent the fluids F1, F2, and F3 in supply paths 31, 32, and 33 from mixing with each other. (Control circuit)
[0061] 8, the control circuit 9 is provided with electromagnetic relays R1, R2, R3 equivalent to the electromagnetic relay R1 in the first embodiment, timers T1, T2, T3 equivalent to the timer T, push button switches PB31, PB32, PB33 equivalent to the push button switch PB3, and PB41, PB42, PB43 equivalent to the push button switch PB4, for each of the fluids F1, F2, F3. Also provided is a three-notch changeover switch SS6 for selecting whether to inject only the fluid F1 during processing, or to inject both the fluids F1 and F2, or both the fluids F1 and F3.
[0062] If the operator operates selector switch SS6 to select the process of pressurizing fluids F1 and F2, during automatic stop operation, a start signal from push button switch PB1 energizes the electromagnetic coil of electromagnetic relay R1 and closes its contact a. When the time elapsed since timer T1 started operating reaches the set delay time, the contact b of timer T1 opens and the contact a closes, thereby deenergizing the electromagnetic coil of electromagnetic relay R1, its contact a opens and deenergizing solenoid SV1, and the electromagnetic coil of electromagnetic relay R2 is energized and its contact a closes, energizing solenoid SV2. When the contact a of timer T1 closes, timer T2 starts operating, and when the time elapsed since timer T2 started operating reaches the set delay time for timer T2, the contact b of timer T1 opens, thereby deenergizing the electromagnetic coil of electromagnetic relay R2 and its contact a opens and deenergizing solenoid SV2.
[0063] Furthermore, when the operator operates the selector switch SS6 to select the process of injecting fluids F1 and F3, the timers T1 and T3, the electromagnetic relays R1 and R3, and the solenoids SV1 and SV3 operate in the same manner as the timers T1 and T2, the electromagnetic relays R1 and R2, and the solenoids SV1 and SV2 when the operator selects the process of injecting fluids F1 and F2.
[0064] Therefore, the control circuit 9 can open and close the valves 41, 42, 43 at the appropriate time by individually energizing or de-energizing the solenoids SV1, SV2, SV3 of the valves 41, 42, 43. Furthermore, when two of the fluids F1, F2, F3, namely, the fluids F1 and F2 or the fluids F1 and F3, are selected, the control circuit 9 operates the valve 41 provided in the supply path 31 for one of the fluids F1 and F2 or the fluids F1 and F3, and then operates the valve 41 provided in the supply path 31 for the other fluid F2 or F3. The valves 42 and 43 provided in the supply paths 31 and 32 or 33 are operated, and the duration of the individual opening operations of the valves 41 and 42 or 41 and 43 in the supply paths 31 and 32 or 31 and 33 for the selected two fluids F1 and F2 or F1 and F3 is configured to be equal to the delay times Ts1 and Ts2 or Ts1 and Ts3 set in the timers T1 and T2 or T1 and T3 for the two fluids, respectively. (operation panel)
[0065] 9 is provided with not only the above-mentioned push button switches PB31, PB41, PB32, PB42, PB33, and PB43, but also a selector switch SS4 and a selector switch SS5. In this respect, the control panel 8 of the second embodiment differs from the control panel 8 of the first embodiment.
[0066] The selector switch SS4 is used to select whether the fish species to be input into the delay time input units 101, 102, and 103 will be input automatically from the fish species detection device 27 or manually by the operator. Furthermore, the selector switch SS5 is used to manually set the fish species determined by the operator to be processed when the selector switch SS4 is used to select whether the fish species will be input manually by the operator. In this embodiment, the fish processed by the fish processing device 1 are two types of fish, red sea bream and yellowtail, but the number of fish species to be processed is not limited to two, and more types of fish may be processed. (Computer input / output section)
[0067] 10 is a block diagram showing the input / output section of a computer C that constitutes the delay time input device 101. The fish species detection device 27 is connected to the input interface section Ci of the computer C, and a fish species detection signal Sk including the identification code KF of the fish species detected by the fish species detection device 27 can be input. Also different from the first embodiment, the a contacts of electromagnetic relays R1, R2, R3, R20, and R30 of the control circuit 9, which correspond to the electromagnetic relay R1 of the first embodiment, are connected, and the output interface section Co is connected to electromagnetic relays Tr1, Tr2, and Tr3, which correspond to the electromagnetic relay Tr of the first embodiment and output the output signals of timers T1, T2, and T3. (Delay time input section)
[0068] 7 have the same configuration and function as the timer T in the first embodiment. Furthermore, delay time input units 101, 102, and 103 have the same configuration and function as each other. Therefore, the delay time input unit 101 will be described as a representative example.
[0069] As shown in Figure 11, the delay time input unit 101 differs from the delay time input unit 10 of the first embodiment mainly in that it is equipped with a fish species memory unit 28 and a fish species input unit 29, that the function memory unit 12 has approximation functions ft1, ft2, etc. for each of a plurality of fish species as shown in Figure 12, and that the function memory unit 12 selects one of the approximation functions ft1, ft2, etc. that corresponds to the fish species stored in the fish species memory unit 28 from among the approximation functions ft1, ft2, etc. that it stores, and prepares it so that it can be used by the required delay time calculation unit 13. (Fish species memory)
[0070] When automatic input of fish species is selected by the selector switch SS4, the fish species memory unit 28 stores the fish species identification code KF when it receives a fish species detection completion signal Sk and a fish species identification code KF from the fish species detection device 27, and can thereafter update the stored fish species identification code KF each time it receives a fish species detection completion signal Sk and a fish species identification code KF.Furthermore, when automatic input of fish species is selected by the selector switch SS4, the fish species memory unit 28 stores the fish species identification code KF when it receives a fish species identification code KF and a fish species setting completion signal Sk0 from the fish species input unit 29, and can thereafter update the stored fish species identification code KF each time it receives a fish species detection completion signal Sk and a fish species identification code KF. (Fish species input section)
[0071] The fish species input unit 29 converts the contact signal from the changeover switch SS5 into the fish species identification code KF, and outputs the fish species identification code KF and a setting completion signal Sk0. (Function memory section)
[0072] 12, the function storage unit 12 includes fish species-specific function storage units 121, 122, 123, etc. that store approximation functions ft1, ft2, ft3, etc. generated for each fish species, a sorting unit 12s, and a selection unit 12c. When the sorting unit 12s receives an approximation function ft from the function input unit 19 or the function generation unit 24, it receives from the fish species storage unit 28 the stored fish species identification code KF and the approximation function ft from the function input unit 19 or the function generation unit 24, and selects one of the fish species-specific function storage units 121, 122, 123, etc. that corresponds to the received identification code KF and stores the received approximation function ft in that unit. When the required delay time calculation unit 13 calculates the required delay time Ts, the selection unit 12c receives the fish species identification code KF stored in the fish species memory unit 28, selects one of the function memory units 121, 122, 123, ... for each fish species that corresponds to the received identification code KF, and stores it as an approximate function ft to be used by the required delay time calculation unit 13.
[0073] In this embodiment, there are two types of fish species to be processed: red sea bream and yellowtail. For example, if the identification code for red sea bream is "1" and the identification code for yellowtail is "2," the sorting unit 12s stores the approximation function ft in the function storage unit 121 for the first fish species as approximation function ft1 when the identification code KF from the fish species storage unit 28 is "1," and stores the approximation function ft in the function storage unit 122 for the second fish species as approximation function ft2 when the identification code KF from the fish species storage unit 28 is "1." Furthermore, the selection unit 12c prepares the approximation function ft1 stored in the function storage unit 121 for the first fish species as the approximation function ft to be used in the required delay time calculation unit 13 when the identification code KF from the fish species storage unit 28 is "1," and stores the approximation function ft2 stored in the function storage unit 122 for the second fish species as the approximation function ft to be used in the required delay time calculation unit 13 when the identification code KF from the fish species storage unit 28 is "1." (Press-fit data storage unit)
[0074] 13, the press-in data storage unit 23 differs from the press-in data storage unit 23 of the first embodiment in that it includes fish species-specific press-in data storage units 231, 232, 233, etc. that store press-in data Dm1, Dm2, Dm3, etc. for each fish species generated according to the fish species, as well as a sorting unit 23s and a selection unit 23c. The sorting unit 23s and the selection unit 23c have the same sorting and selection functions as the sorting unit 12s and the selection unit 12c described above.
[0075] That is, when the sorting unit 23s inputs the fish size measurement value Wm from the fish size memory unit 11 or the actual pressure-fitting time Tm from the actual pressure-fitting time memory unit 22, it receives the fish species identification code KF stored in the fish species memory unit 28 and the fish size measurement value Wm and the actual pressure-fitting time Tm from the fish size memory unit 11 and the actual pressure-fitting time memory unit 22, and selects one of the pressure-fitting data memories 231, 232, 233, etc. that corresponds to the received identification code KF and stores the received fish size measurement value Wm and actual pressure-fitting time Tm in that memory. When the required delay time calculation unit 13 calculates the required delay time Ts, the selection unit 23c receives the fish species identification code KF stored in the fish species memory unit 28, selects one of the injection data 231, 232, 233, ... for each fish species that corresponds to the received identification code KF, and stores it as injection data Dm to be used in the function generation unit 24.
[0076] This method of processing fish using the fish processing device 1 differs from the method of processing fish using the fish processing device 1 of the first embodiment in that, when processing fish, the identification code KF of the fish species to be processed is stored in the fish species memory unit 28 before the automatic pressing process or the manual pressing process.
[0077] To store the identification code KF in the fish species memory unit 28, the operator selects automatic detection of the fish species with the selector switch SS4 and inputs it from the fish species detection device 27, or the operator selects manual setting with the selector switch SS4 and then selects the fish species of the fish to be processed that the operator has identified with the selector switch SS5 and inputs it from the fish species input unit 29.
[0078] FIG. 14 shows another example of a data table related to the injection data Dm. The injection data Dm in this data table is used when inputting the injection data Dm from the injection data input unit 25 shown in FIG. 5 or 11 to the injection data storage unit 23 or from the function input unit 19 to the function storage unit 12. The data table includes the fish size measurement value Wm, the measurement value of the time required to inject the fluid F into the fish (i.e., the actual injection time Tm), and the K value measured after a predetermined period of time for the fish. This injection data Dm generates an approximation function based on an objective K value rather than on the experience and intuition of a skilled person, allowing for a more appropriate amount of fluid to be injected. Furthermore, it is preferable to create a data table by extracting individual data with a K value below a certain level from the data table shown in FIG. 14, and then create the injection data Dm for that data table.
[0079] Fish muscles contain a substance called adenosine triphosphate (ATP), which serves as an energy source for movement. After a fish dies, adenosine triphosphate (ATP) is broken down into adenosine diphosphate (ADP), adenylic acid (AMP), inosinic acid (IMP), inosine (HxR), and hypoxanthine (Hx). The K value is an objective index of fish freshness. The K value can be calculated as K(%) = (Hxr + Hx) / (ATP + ADP + AMP + IMP + HxR + Hx) x 100, and the smaller the value, the fresher the fish. (Third embodiment)
[0080] The fish processing device 1 according to the third embodiment of the present invention is further provided with a trained model that outputs a correction time for correcting the delay time Ts.
[0081] Specifically, the trained model is a trained model generated by machine learning training data, and the training data may include information related to the condition of the fish before and after processing, information about the processing device, information about the person who performed the processing, information about the climate, etc. The trained model generated in this manner uses information related to the condition of the fish before processing, information about the processing device, information about the person who performed the processing, information about the climate, etc. as input data, and outputs output data that is data related to a correction time for correcting the delay time.
[0082] The output data is data in the form of, for example, "+xx seconds" or "-xx seconds", and by adding this to the delay time Ts, the delay time Ts can be corrected.
[0083] In other words, the fish processing device 1 of the third embodiment of the present invention is equipped with a trained model, and can output a correction time that takes into account, for example, individual differences in fish and processing devices, differences in the person performing the processing (operating habits), differences in climate, etc., which are difficult to judge mechanically, and can be reflected in the delay time Ts.
[0084] Information relating to the condition of the fish before processing may include information relating to the size of the fish, such as total length, head size, fin size, weight, and volume, as well as the color of the fish and whether it is alive or not. Information relating to the condition of the fish after processing may include information relating to the size of the fish, color of the fish flesh, time until decay, smell, firmness of the flesh, taste, etc.
[0085] Furthermore, the methods for acquiring and inputting the training data and input data are not particularly limited. For example, this can be achieved by recording information on previous fish processing using the fish processing device 1 and manually inputting this information. Information regarding fish size may be acquired using the weighing device 6 and automatically input. For example, the fish processing device 1 may be equipped with an imaging unit, and information regarding fish size, color, liveliness, flesh color, and time until decay may be acquired from images (videos and still images). Information such as time until decay, odor, flesh firmness, and taste can be acquired, for example, by sensory testing. In this case, if data related to the tester is also included in the training data, the influence of variations in tester judgment can be reduced. (Fourth embodiment)
[0086] 15 shows a fish treatment device according to a fourth embodiment of the present invention. This fourth embodiment differs from the first to third embodiments in that the amount of fluid F injected into the vascular system of the fish is determined by the cumulative flow rate of the fluid F passing through the supply path 3 to the annular device 2, whereas the amount of fluid F injected into the vascular system of the fish is determined by the injection time. In the fish processing device 1, the control device 5 includes a required injection amount setting unit 10A that sets a required injection amount of the fluid F, an integrating flow meter 5a that measures the integrated flow rate of the fluid F passing through the supply path 3 from moment to moment, a comparison unit 17A that compares the calculated value Vs of the required injection amount of the fluid F by the required injection amount setting unit 10A with the measured value vm of the integrated flow rate of the fluid F from moment to moment by the integrating flow meter 5a, and issues a stop signal when the measured value vm of the integrated flow rate of the fluid F from moment to moment reaches the calculated value Vs of the required injection amount of the fluid F, and a comparison unit 17B that outputs a stop signal when the valve 4 starts to open, that is, from the time when the start signal for fluid injection is issued until the stop signal is issued by the comparison unit 17A. 17, in place of the function memory unit 12 and required delay time calculation unit 13 shown in FIG. 5, the required injection amount setting unit 10A is equipped with a function memory unit 12A that stores an approximation function fv in which the measurement value w of the fish size is an independent variable and the required injection amount v of fluid for the fish is a dependent variable, as shown in FIG. 17, and a required delay time calculation unit 13A that calculates the required injection amount Vs of fluid F for the fish based on the measurement value Vm of the actual injection amount of fish size measured by the weighing device 6 and the approximation function fv.
[0087] The control circuit 9A shown in FIG. 16 has a b-contact of an electromagnetic relay Rs instead of the b-contact of the timer T shown in FIG. 2. When the comparison unit 17A outputs a stop signal, the electromagnetic coil of this electromagnetic relay Rs is excited to open the b-contact, and this electromagnetic relay Rs is provided in place of the electromagnetic relay Tr shown in FIG. 4.
[0088] The required injection amount setting unit 10A shown in FIG. 17 includes an injection amount measurement unit 21A and an actual injection amount storage unit 22A. The injection amount measurement unit 21A continuously receives measurement signals from the integrating flow meter 5a and outputs to the comparison unit 17A the measured value vm of the integrated flow rate of the fluid F passing through the supply path 3 from the time a start signal is issued until a stop signal is issued. When the comparison unit 17A issues a stop signal, the measured value vm of the integrated flow rate at that time is input to and stored in the actual injection amount storage unit 22A as the actual injection amount Vm.
[0089] The integrating flow meter 5a outputs a pulse signal each time a predetermined amount of fluid F passes through the supply path 3, and the injection amount measuring unit 21A is able to calculate the integrated flow rate vm by counting the pulse signals from the integrating flow meter 5a using a counter circuit.
[0090] The required press-in amount setting unit 10A is equipped with a function input unit 19A, a press-in amount measurement unit 21A, a measured press-in amount storage unit 22A, a press-in data storage unit 23A, a function generation unit 24A, and a pressure data input unit 25A, in which the measured press-in time Tm, which is one of the components of the press-in data storage unit 23, the function generation unit 24, and the pressure data input unit 25 shown in Fig. 5, is replaced with the measured press-in amount Vm. The function generation unit 24A stores an equation for calculating the coefficients α and β of the approximate function fv (v = αw + β) by the least squares method based on the press-in data Dm stored in the press-in data storage unit 23A. When the press-fit data Dm stored in the press-fit data storage unit 23A is obtained by replacing the individual measured press-fit times t1, t2, t3...tk...tn in the press-fit data A shown in FIG. 6 with the individual measured press-fit amounts v1, v2v3...vk...vn, the coefficients α and β can be calculated by the following Equations 3 and 4.

number
[0091] The control device 5 of the fish processing apparatus 1 according to the fourth embodiment can be applied to the control device 5 of the fish processing apparatus 1 according to the second embodiment. To this end, the input time measurement unit 21, the measured injection time memory unit 22, the output unit 14, and the timer T in the delay time input unit 101 shown in FIG. 11 are replaced with an injection amount measurement unit 21A that receives a measurement signal from an integrating flow meter 5a, an actual injection amount memory unit 22A, an output unit 14A, and a comparison unit 17A shown in FIG. 17. Furthermore, the function memory units 121, 122, 123, etc. for each fish species in the function memory unit 12 shown in FIGS. 11 and 12 are each replaced with the function memory unit 12A shown in FIG. 17. Furthermore, the injection data memory units 231, 232, 233, etc. for each fish species in the injection data memory unit 23 shown in FIGS. 11 and 13 are each replaced with the injection data memory unit 23A shown in FIG. 17. 11 are replaced with a function generator 24A, a required delay time calculator 13A, an injection data input unit 25A, and a function input unit 19A. This allows the amount of fluid F injected into the fish to be determined by the integrated flow rate of fluid F passing through the supply path 3 to the annular device 2, and the valve 3 to be closed when the actual injection rate Vm, which is the measurement value of the integrated flow rate, reaches the required injection rate Vs, making it possible to inject an appropriate amount of fluid F into the vascular system of the fish depending on the species of fish. Fifth Embodiment
[0092] Figure 18 shows a fish processing device according to a fifth embodiment of the present invention, in which this fish processing device 1 is provided with a pump 7b that discharges fluid F from a container 7a into a supply path 3 for supplying fluid F connected to a tubular device 2, and differs from the fish processing device 1 according to the first to fourth embodiments of the present invention in that the control device 5 controls the start and stop operation of a motor 7j that drives the pump 7a so that the amount of fluid F pressed in is the required amount.
[0093] According to the present invention, for example, in the press-fit data shown in Fig. 14, individual data having a K value equal to or less than a certain value can be extracted to create new press-fit data, and this new press-fit data can be input into press-fit data storage unit 23 or press-fit data storage unit 23A via press-fit data input unit 25 instead of the press-fit data shown in Fig. 6, thereby enabling a more appropriate amount of fluid to be pressed in than by an expert. Also, for example, selector switch SS1, selector switch SS2, selector switch SS3, measurement value display unit 6a, measurement value input unit 26, push button switch PB6, push button switch PB4, measurement value input unit 26, press-fit data input units 25, 25A, and function input units 19, 19A may be omitted. The control circuits 9 and 9A shown in Figures 2, 8, and 16 are examples of control circuits. In the control circuit 9 shown in Figure 2, pushbutton switch PB1 can be operated to issue a start signal and PB2 can be operated to issue a forced stop signal during automatic stop operation. During manual stop operation, pushbutton switch PB3 can be operated to issue a start signal and pushbutton switch PB4 can be operated to issue a stop signal. However, pushbutton switches PB3 and PB4 may be omitted by configuring the circuit so that a common pushbutton switch PB1 can be operated to issue a start signal and pushbutton switch PB2 can be operated to issue a stop signal during both manual and automatic stop operation. The same can be said for the control circuits 9 and 9A shown in Figures 8 and 16. The control circuit 9 shown in Figures 2, 8, and 16 may be configured inside the computer C, and a contactless relay may be used instead of an electromagnetic relay. Furthermore, instead of a linear function of fish size, a quadratic function or a higher-order function of fish size can be used as the approximation function stored in function storage unit 13, if necessary. Furthermore, if a problematic error occurs between the calculated required press-in time and the delay time that should actually be set, output unit 14 or output unit 14A of delay time input unit 10 may be provided with a function to correct the error.
