Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blood sampling device for hygienically and efficiently collecting blood from animals such as livestock such as cows and pigs when the animals are slaughtered.

Currently, when slaughtering at slaughterhouses, cows are slaughtered using the beating method, and pigs are left unconscious by electrocution or gas and killed by natural exsanguination by being stabbed in the throat with a knife while lying down. .

At this time, the blood discharged onto the floor etc. is introduced into a septic tank together with washing water and as wastewater from the funeral home, and is discharged after treatment.

However, as mentioned above, the method that relies entirely on natural exsanguination during slaughter is unhygienic as the blood drips onto the floor, etc., and now that the pollution problem around Odaiba is becoming more and more serious. That's not an effective method. or,
Since such dripping blood is contaminated, it must be treated as funeral home wastewater, as described above, and a large amount of money is required to construct and operate and maintain a purification facility. The reality is that the number of animals slaughtered is limited by the scale of the purification equipment.Furthermore, the blood, which is an effective protein resource, is dried and powdered and widely used as feed, fertilizer, food additives, medicines, etc. This was a far cry from the current trend towards achieving this goal.

In view of the above-mentioned conventional circumstances, the present invention has been developed to collect blood directly from the animal's body, and to automatically perform this blood collection process to shorten the blood collection time, thereby achieving a sanitary and efficient method. An animal blood sampling device that collects blood, thereby improving the sound field environment, making effective use of blood, and thereby reducing the load on slaughter wastewater purification facilities in the sound field. It provides:

The six blood sampling hoses 8 are supported by the outer circumferential walls of the blood sampling hoses 8, and are connected to nozzles provided on the pipe body 5a of the blood sampling knife 5.

Reference numeral 18 denotes a blood discharge nozzle (11) connected to the lower part of the blood collecting tray 16, which is connected to a blood tank 19 disposed underground via a pipe 19A.

The blood tank 19 temporarily stores collected blood until it is sent to the next process.

Next, referring to FIGS. 6 and 7 as well, the explanation will be as follows:
20 is a cleaning liquid discharge nozzle connected to the lower part of the receiving tray 17; 21 is a cleaning liquid tank connected to the nozzle 20 through piping 21A; and 22 is a cleaning liquid discharge nozzle for pressure-feeding the cleaning liquid in the cleaning liquid tank 21 into the blood collection hose 8. This is a cleaning liquid feed pump.

A pipe 23A connected to the discharge side of the pump 22 is connected to the hose nozzle 1 through a nozzle 23B in the receiving tray 17.
0 comes to a predetermined position by rotating the rotary pole 10 times, so that it faces the hose nozzle 10 with a slight distance therebetween. Reference numeral 23C is a solenoid valve installed in the pipe 23A, and is opened and closed by a sequence control device to be described later. Further, 23D is a minimum flow pipe that branches from the pipe 23A and returns the cleaning liquid to the cleaning liquid tank 21 via an orifice 23E, and 23F is a minimum flow pipe that branches from the pipe 23A and returns the cleaning liquid to the cleaning liquid tank 21.
(12) This is piping that connects the pump 22.

Then, when the hose nozzle 10 rotates together with the rotating pole 1 and comes to face either the hose nozzle 10 or the nozzle 23B, the solenoid valve 23C is opened and the cleaning liquid in the cleaning liquid tank 21 is pumped 22. It ascends into the blood sampling hose 8 and blood sampling knife 5 via the piping 23A and the nozzle 23B. Furthermore, when the hose nozzle 10 rotates and the nozzle 23B no longer faces the hose nozzle 10, the solenoid valve 23C closes and the cleaning liquid in the blood collection hose 8 and blood collection knife 5 returns to the receiving tray 17, and the receiving tray 17 is removed. Piping 2
It is designed to be returned to the cleaning liquid tank 21 via Gravity or a pump (not shown) through 1A.

The slip ring 26 is for supplying power to each electromagnetic valve 12 that rotates together with the rotary pole 1.
It passes through the center of IA and the rotating pole 1 together with the in-machine piping 27, passes through the outer circumferential wall of the rotating ball 1 in front of the chamber 11, and is connected to each electromagnetic valve 12.

(13) Reference numeral 29 is a foot switch for operating the above-mentioned aircraft body, which is used when the machine is single-acting. In this embodiment, continuous automatic operation can be performed by turning on an automatic start switch on a separately provided operation panel.

On the other hand, in FIG.
An automatic stopper NQ2 has the purpose of stopping the trolley 40 on which the livestock 39 is suspended at a predetermined position on the blood collection rail 30, and is automatically opened and closed by a signal from the sequence control device.

Here, the automatic stopper Nnl 31 stops a predetermined number of livestock 39.
The automatic stopper N11232 is used to stop the livestock 39 at the blood collection location.

33 to 36 are sensor holes 1 to 4, each of which is constituted by a phototube or a limit switch, and detects the position of the trolley 40 sent onto the blood collection rail 30 and outputs a signal.

And the sensor hole 133 is an automatic stopper I'I! 113
1 (14), the sensor 1V1k1234 outputs a signal to activate the anticoagulant timer and the livestock feed timer that control the opening and closing of the anticoagulant solution solenoid valve 12, which will be described later, and the sensor M335 starts the electric motor 24. Gives a signal to the sensor%
436 outputs a signal to stop the electric motor 24 and a signal to open and close the cleaning liquid electromagnetic valve 23C.

Here, as the rotating ball 1 rotates,
Feed arm 2, pulleys 3A, 3B, hanging arm 4, blood sampling knife 5, balance weight rotor.

Wire 7, blood collection hose 8. Purulent cover 9, hose nozzle 10, chamber 11. Solenoid valve 12. The E-section valve 13 and hose 14 are all rotated.

That is, this rotary ball 1 transports the blood sampling knife support device and the blood sampling knife to a livestock animal suspended and supported by the hanging device via a feed arm 2 serving as a blood sampling conveyor that moves the hanging device. The blood sampling knife 5 is pierced into the livestock 39 at a position corresponding to the position 39 from when the livestock 39 comes to the blood collection position until the blood collection is completed.

Next, the operation of this embodiment device will be explained.

At position X in FIG. 5, the operator attaches the other end of the hanging chain 53 shown in FIG.
hook 54 on trolley 40 on 0.

Next, when the trolley 40 with the livestock 39 coupled thereto is operated by the trolley lift 50 and thereby lifted and transferred to the blood collection rail 30B located at a higher position than the blood collection rail 30A, the trolley 40 is moved because the blood collection rail 30B is on a downward slope. It descends along the blood collection rail 30B in the direction of the arrow in the figure and is stopped by the automatic stopper NQ131 in the closed state.

A plurality of trolleys 40 with livestock 39 coupled thereto remain in front of this automatic stopper 131 through the above-described operation.

When the automatic stopper I'k131 is opened in response to a start signal from the sequence control device, one trolley 40 passes through the automatic stopper I'%131 and moves toward the automatic stopper I'k131 and the automatic stopper I'k131. And sensor 1
33 detects the trolley 40, the automatic stopper 111kL131 closes immediately. As described above, only one trolley 40 is sent out. Next, when the trolley 40 moves and the sensor block 234 detects this, the anticoagulant timer and livestock feed timer of the sequence control device are activated, and the anticoagulant timer opens the solenoid valve 12 for anticoagulant solution. shall be.

Incidentally, anticoagulant timers are provided corresponding to the number of anticoagulant solution electromagnetic valves 12, and the activated anticoagulant timer is connected to the electromagnetic valve 12 corresponding to the blood sampling knife 5 at position Z in FIG. control.

Almost at the same time, the trolley 40 stops at the automatic stopper 2.
Stops at 32.

Therefore, the worker uses the trolley 40 from which the livestock 39 is suspended.
The work of stabbing the blood sampling knife 5 at the Z position on the nearer side into the livestock 39 is performed. The livestock feed timer is set to the time required to pierce the livestock 39 with the blood sampling knife 5, and when the work is completed, the automatic stopper 1VIkL23
2 & open.

(As mentioned above, when the automatic stopper 232 is opened, the trolley 40 moves to the position of the sensor 335 due to its own weight due to the downward slope of the blood collection rail 30B.
Automatic stopper 232 when detecting trolley 35 or 40
is closed and the electric motor 24 shown in FIG. 2 is started.
The rotary pole 1 is driven to rotate, and the feed arm 2 rotates as shown by the arrow in the figure.

The rotating feed arm 2 presses against the Toro IJ-40k and moves on the blood sampling rail 30B against the slope of the blood sampling rail 30B.

When the trolley 40 is on the blood collection rail 30B, the sensor N[
When detected by 1436, the electric motor 24 is turned off and stops operating.

If one cycle of blood collection is completed by the above, or if automatic start-up is performed thereafter, move to the next trolley 40 or automatic stopper N113.
1 is open and 1. By doing this, the above cycle is automatically repeated.

Also, when using single action, use the foot switch 29,
By turning on this switch 29 (18), only the next cycle is operated.

The anticoagulant timer has a time required for blood collection set according to the 390 types of livestock to be blood sampled, the amount of blood sampled, etc., and closes the anticoagulant solution electromagnetic valve 12 when the blood sampling operation is completed.

Then, when the trolley 40 suspending the livestock 39 from which blood has been collected moves to point D shown in FIG.
Since the blood sampling knife 5 that has been stuck into the livestock 39 attempts to move along the blood sampling rail 30B with a downward slope after point D, the blood sampling knife 5 that has been stuck into the livestock 39 naturally comes off from the livestock 39.

The detached blood sampling knife 5 is supported in a lifted state by the wire 7 shown in FIG. 1, and proceeds to the cleaning step.

When the hose nozzle 10 of the blood collection hose 8 comes into contact with the washing liquid nozzle 23B (set at a position W at 60 degrees in the direction of movement from the fifth sampling point), this is detected by the sensor depression 436. The solenoid valve 23C is opened, and the cleaning liquid rises to the hose nozzle 10, (19) blood collection hose 8, and blood collection knife 5 to clean them. In this case, the hose nozzle 10. The cleaning liquid that has risen to the blood sampling hose 8 and blood sampling knife 5 passes through them and returns to the receiving tray 17, and from there is guided to the nozzle 20 by the guide plate 17A, passes through the piping 21, and enters the cleaning liquid tank 21.
Go back inside. Note that cleaning performance is better if the supply pressure of the cleaning liquid is set high so that the cleaning liquid is spouted from the tip of the blood sampling knife 5. In this case, as shown in FIG. A container 55 for receiving the water is provided. Then, when the sensor Nn436 no longer detects the trolley 40, the cleaning liquid electromagnetic valve 23C is closed and the cleaning liquid supply is stopped.

As described above, blood collection from the livestock 39 is performed. When the blood sampling knife 5 is pierced into the livestock 39, the blood of the livestock 39 is collected through the blood sampling knife 5 and the blood sampling hose 8 due to gravity. The blood flows down into the tray 16, from where it passes through the nozzle 18 and from the pipe 19A to the blood tank 19.
It reaches inside and is stocked here.

(20) On the other hand, the trolley 40, which has descended by its own weight along the downward slope of the blood collection rail 30B from point D to point E in FIG.
The blood sample is transferred to the blood collection rail 30A located at a lower position than B. Here, the worker places the hook 5 of this trolley 40 at the Y position.
The chain 53 connected to the livestock 39 is removed from 4 and the livestock 39 is lowered. The empty trolley 40 moves by its own weight along the blood collection rail 30A, which has a downward slope, and reaches point A where it should be connected to the livestock 39 again.

In the embodiment described above, as described above, the blood collection conveyor according to the present invention is provided by the feed arm 2, the hanging device is provided by the blood collection rail 30 and the trolley 40, the blood collection knife tool is provided by the blood collection knife 5 and the blood collection hose 8, and the blood collection knife device is provided by the pulley 3A. ,3B
The hanging arm 4, the balance weight rod, the wire 7, and the hose nozzle 10 constitute a blood sampling knife support device, and the rotary pole 1 constitutes a blood sampling knife moving device. is (2
1) After being suspended from the -H trolley 40, the livestock 39 that is suspended from the trolley 40 is automatically sent to the line according to the blood collection rail 30 configured on a predetermined rail until the blood collection work is completed, and the livestock 39 that is suspended from the trolley 40 is moved. Since blood is collected continuously using a blood sampling knife that moves in synchronization with the movement of the blood sampling knife, the operator has to perform two tasks: suspending the livestock 39, stabbing the blood sampling knife 5 raised to a predetermined height, and The blood collection work can be carried out extremely efficiently, smoothly and quickly by simply removing the blood from the livestock 39. The blood is collected into the designated blood collection tray 16 through the blood collection knife 5 or the blood collection hose 8 without dripping, so there is no need for blood to spill onto the floor of the funeral hall as in the past. It is possible to greatly improve the hygiene of the funeral home and prevent pollution caused by blood dripping.Furthermore, by taking out the blood hygienically, other impurities will not be mixed in with the blood. It is possible to fully satisfy the recent trend of using blood as an effective protein resource (22) as feed, fertilizer, food additives, and medicines. The use of this method eliminates the need to discharge blood as slaughter wastewater, which reduces the burden on blood purification facilities, reducing costs and reducing the number of animals slaughtered due to the size of purification facilities. The actual situation can be resolved.

In addition, in the above structure, one end of the string material for hanging the blood sampling knife, such as the wire 7, is connected to the other end of the string material, so that the blood sampling knife is always held upward. By providing a blood sampling knife support device equipped with a balance weight roller that can be pulled up to the position of the blood sampling knife and changed to the vertical position in a balanced manner according to the vertical position of the blood sampling knife, the blood sampling knife can be always positioned at a predetermined height. Since the blood sampling knife 5 can be moved in a fixed state, the blood sampling knife 5 will not fall off from the animal even if it is removed even after stabbing the animal with the blood sampling knife 5, and the blood sampling knife tool can be kept hanging on the floor at all times. This eliminates the need to hold the blood sampling knife in a lowered position (as in the 2-way configuration, where the blood sampling knife tool has to be raised on the floor and brought to the animal position). The blood sampling knife 5 is not dragged on the floor when not in operation.
This is advantageous in terms of work and hygiene since the floor surface will not be soiled by blood deposits on the floor. Incidentally, in a configuration in which the blood sampling knife moves while being dragged along the floor, there is a disadvantage that the configuration is complicated, such as the need to provide a receiving tray for the blood sampling knife in the area where the blood sampling knife moves. Furthermore, the blood sampling knife tool is not simply suspended upward, but its height can be adjusted as appropriate by balancing it with a balance weight trolley, so it is possible to adjust the height of the blood sampling knife as appropriate by adjusting the height of the hanging animal. This has the advantage that even if the lengths of the two sides are different, it can be easily accommodated.

According to this embodiment, since a device is provided that automatically adds an anticoagulant solution to blood at the same time as blood is collected, the operator can perform anticoagulation (addition of anticoagulant solution) manually or the like every time blood is collected. There is no need to perform additional work, and from this aspect as well, blood collection work can be made more efficient.Furthermore, a device for supplying cleaning liquid to the blood sampling knife used for blood sampling and cleaning it can be added to the blood sampling knife supporting and moving device. The built-in structure automatically supplies cleaning fluid to the blood sampling knife tool after blood collection, so the operator still has to do this manually.

The work of cleaning the blood sampling knife can be omitted, and workability can be improved.

In the above-mentioned embodiment, the blood sampling rail 30 shown in FIG. The rail may be constructed as a completely downward slope.

In this case, the original music 39 moves from the suspended trolley 40 to point 0 at point A, and further movement is prevented by locking the front end of the trolley 40 with the feed arm 2 in front of the trolley 40. , the feed arm is moved at a speed of 20 rotations.

Then, by setting the blood sampling position to point 07 in the figure (2
Since the trolley 40 can be locked at the 07 point, the automatic stopper 232 can be omitted.
4 can also be omitted.

In this case, when the sensor arm 335 detects the trolley 40, it outputs a signal to activate the anticoagulant timer and the livestock feed timer, and the trolley 40 is locked to the feed arm 2 located ahead of it at point 07. At this point, urine volume is 39 and blood sampling knife is 5? : Piercing.

When the work is completed, the livestock feed timer is set to the electric motor 2.
All you have to do is issue a signal to activate 4.

According to this configuration, as described above, the automatic stopper I'!
1232 and sensor hole 234 can be omitted, and the structure of the sequence control device can be simplified.

Further, in the above embodiment, the feed arm 2 that rotates
A blood collection rail 30 is disposed in a three-dimensional movement range, and a trolley 40 on the blood collection rail 30 is pressed and moved by the feed arm 2, but the trolley is not directly locked to this feed arm. This (26) embodiment is shown in FIGS. 8 to 12.

This is the place where livestock are removed from roller conveyor 11.
etc. are equipped.

This point B is also a place where livestock is loaded onto the elevated blood collection rail 57A using the empty trolley 58 or trolley lift 65 from which the livestock has been removed.

The sensor indicated by 72 in the figure serves as a signal to stop the rotary ball drive motor, a signal to open and close the cleaning liquid electromagnetic valve, and an anticoagulant timer to open and close the extraction device 69 and the anticoagulant solution electromagnetic valve. This signal is used to issue an activation signal, and may be provided at a position corresponding to the position of the tip of one of the feed arms 56 when the tips of the three feed arms 56 are located at point A, point 0, or point D.

Next, the operation of this embodiment device will be explained.

In FIG. 8, the empty trolley 58 on the blood collection rail 57A descends along the rail 57A in the direction of the arrow in the figure because the rail 57A has a downward slope (30).
There are multiple parts in front of the automatic stopper 66 in the closed state. On the other hand, since the operation of the rotating ball 59 is intermittently stopped when the feed arm 56 comes to the sensor foot position,
When the tip of each feed arm 56 reaches the D position, E position, A position, or C position, the feed arm 56 stops, and at the C position, the tip of the blood collection rail 57A and the support rail 64 of the trolley support section 61 are aligned. It is in a state where

Therefore, when the automatic strainer 66 is opened in response to a start signal from the sequence control device, one empty trolley 58 passes through the automatic stopper 66 and reaches the sensor 67.
The sensor 67 detects the trolley 58, and immediately the automatic stopper 66 closes and the sensor 6T activates the livestock feeding timer.

As described above, only one trolley 58 is sent out, and the trolley 58 rides on the support rail 64 as shown in the figure and is held in the trolley storage space 62 (31). Then, after a predetermined time, the livestock feeding timer starts the rotating ball electric motor, and the feed arm 56 is in the D position and the E position.
It advances intermittently to position and A position.

At the D position, the work of hanging the livestock onto the trolley is carried out, and at the E position, the anticoagulant is sent to the blood sampling knife that has moved in synchronization with the feed arm (the anticoagulant timer is activated), The operation of stabbing the blood sampling knife into the livestock is performed.

At the A position, the trolley support part 6 holds the livestock whose blood collection work has been completed while moving from the E position to the A position.
The support rail 64 of No. 1 and the tip of the blood collection rail 57B match, and at this point, the cylinder device 7 is activated by the signal from the sensor 72.
The retaining part at the tip of the piston door 0A is the trolley 58.
The piston door 0A is activated to pull the trolley 58 toward the front, and the trolley 5
8 from the rail 64 of the trolley support part 61 to the blood collection rail 5
At the same time as the movement to the 7B side is performed, the blood sampling knife 5 that had been stuck in the livestock comes off naturally.

It descends along the downward slope blood collection rail 57B (32
) After the livestock is removed from the trolley 58 at position B, it is placed on the blood collection rail 57A again by the trolley lift 65.

In this embodiment, the livestock feeding timer is at position A;
It is set to the maximum time required for each operation at the B position, C position, D position, and E position. The anticoagulant solution supply device and the cleaning fluid supply device are constructed in the same manner as in the previous embodiment.

According to the configuration of the above embodiment, since the livestock is directly moved by the feed arm 56, there is no need to arrange a blood collection rail in the three-dimensional movement range of the feed arm as in the previous embodiment. The construction work of the blood collection rail becomes simple, and if the livestock is hung on the trolley 58, the feed arm 56 transports the livestock to the line at that position.
Unlike the previous example, there is no need to lift livestock suspended from a trolley to a high position and send them onto the blood collection rail, and the trolley lifter that performs this operation can be omitted. There are advantages in terms of simplification and manufacturing cost of the device (33).
