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 cattle at slaughterhouses, pigs are mainly killed by the hammering method, and pigs are left unconscious by electrocution or gas slaughter, then left lying on their back and stabbed in the throat with a stab knife to die of natural exsanguination.

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

However, as mentioned above, the method in which exsanguination during slaughter relies entirely on natural exsanguination is unhygienic as the exsanguinated blood drips onto the floor, etc., and the problem of pollution around funeral halls is increasing. That's not an effective method.

In addition, since such dripping blood is contaminated, it must be treated as slaughterhouse wastewater as mentioned above, which requires a large amount of money to construct and operate and maintain purification facilities. The reality is that the number of animals slaughtered is limited by the size of the purification equipment.Furthermore, the blood, which is an effective protein resource, is dried and turned into powder, which is widely used as feed, fertilizer9, 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. To provide an animal blood sampling device that can collect blood, thereby improving the environment of a slaughterhouse, making effective use of blood, and thereby reducing the load on a slaughterhouse wastewater purification facility. be.

Reference numeral 29 is a foot switch for operating the above-mentioned aircraft body, which is used in the case of single action.

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. 5, 31 is the automatic stopper shadow 1.32
is an automatic stopper I6.2 whose purpose is to stop 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 A131 is used for the purpose of storing a predetermined number of livestock 39 at a predetermined position and sending out the trolley 40 (livestock 39) one by one to the blood collection location, and the automatic stopper plate 232 is used to collect the livestock 39 at the blood collection location. Used to stop.

33 to 36 are sensors A1 to A1 and A4, each of which is composed of 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.

Then, the sensor A 133 outputs a signal to close the automatic stopper washer 131, and the sensor washer 234 outputs a signal to operate an anticoagulant timer and a livestock feeding timer that control the opening and closing of an anticoagulant solution solenoid valve 12, which will be described later. A335 outputs a signal to start the electric motor 24, and a sensor A436 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 pole 1 rotates, the sending arm 2, pulleys 3A, 3B, hanging arm 4,
Blood collection knife 5, balance weight roller, wire 7, blood collection hose 8, protective cover 9, hose nozzle 10, chamber 11. The solenoid valve 12, control valve 13, and hose 14 are all rotated.

That is, the rotary pole 1 in the blood sampling knife support and movement device moves the blood sampling knife to the livestock 39 suspended and supported by the hanging device via the feed arm 2, which serves as a blood sampling conveyor that moves the hanging device. The blood sampling knife 5 is moved to a position corresponding to the position from when the domestic animal 39 comes to the blood sampling position until the blood sampling is completed when the blood sampling knife 5 is stabbed into the domestic animal 39.

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.
Engage the hook 54 on the upper trolley 40.

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 A; , 1 31 in the closed state.

In front of this automatic stopper A131, a plurality of trolleys 40 with livestock 39 coupled thereto remain in front of the automatic stopper A131.

When the automatic stopper A131 is opened in response to a start signal from the sequence control device, one trolley 40 passes through the automatic stopper A131 and moves toward the automatic stopper A232.

Then, as soon as the sensor A 133 detects the trolley 40, the automatic stopper foot 131 closes.

As described above, only one trolley 40 is sent out.

Next, the trolley 40 moves and carries the sensor A2.
34 activates the anticoagulant timer and livestock feed timer of the sequence controller, and the anticoagulant timer opens the anticoagulant solution solenoid valve 12.

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. It controls the

Almost at the same time, the trolley 40 moves to the automatic stopper A2.
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 feeding timer is set to the time required to pierce the livestock 39 with the blood sampling knife 5, and when the operation is completed, an automatic stopper is activated. , 2 32 is opened.

When the automatic stopper A232 is opened as described above, the trolley 40 moves to the position of the sensor A335 due to its own weight due to the downward slope of the blood collection rail 30B.

When this sensor A335 detects the trolley 40, the automatic stopper A232 closes and the electric motor 24 shown in FIG. 2 is started, the rotary pole 1 is driven to rotate and the feed arm 2 is rotated as shown by the arrow in the figure.

The rotationally moving feed arm 2 pushes the trolley 40 against the slope of the blood collection rail 30B and moves the blood collection rail 30B against the slope of the blood collection rail 30B.
Move on B.

When the trolley 40 is on the blood collection rail 30B, the sensor A4
36, the electric motor 24 is turned off and stops operating.

One cycle of blood collection is completed as described above, but from now on, when automatic startup is performed, the next trolley 40 will be moved to the automatic stopper A131.
The above cycle is automatically repeated by opening.

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

The anticoagulant timer has a time required for blood collection set according to the type of livestock 39 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 blood-collected livestock 39 moves to point D shown in FIG.
While attempting to move along the downwardly sloped blood sampling rail 30B after point D, the blood sampling knife 5 that had 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 of 60° in the direction of movement from the fifth sampling point), this is detected by the sensor A436 and electromagnetic The valve 23C is opened, and the cleaning liquid rises to the hose nozzle 10, blood collection hose 8, and blood collection knife 5 to clean them.

In this case, the cleaning liquid that has risen to the hose nozzle 10, blood collection hose 8, and blood collection knife 5 passes through these and is placed in the receiving tray 1.
Return to the inside of the nozzle 20 from here using the guide plate 17A.
The liquid is guided back into the cleaning liquid tank 21 through the pipe 21A.

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 plate 436 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 sampling 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 via the blood sampling knife 5 and the blood sampling hose 8 due to gravity. Blood flows down into the tray 16, from where it flows through the nozzle 18 and from the pipe 19A to the blood tank 19.
It reaches inside and is stocked here.

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 operator removes the chain 53 connected to the livestock 39 from the hook 54 of the trolley 40 at the Y position and lowers the livestock 39.

The empty trolley 40 moves by its own weight along the downwardly sloping blood collection rail 3OA and reaches point A where the livestock 39 is to be connected 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
A blood sampling knife supporting and moving device is constituted by a hanging arm 4, a balance weight trolley, a wire 7, a hose nozzle 10, and a rotating pole 1. After the blood is suspended from the trolley 40, the blood is sent to the line dynamically according to the blood collection rail 30 configured on a predetermined rail until the blood collection is completed, and the blood is moved in synchronization with the movement of the livestock 39 suspended from the trolley 40. Since blood sampling is performed continuously using a blood sampling knife tool, the worker can easily complete the blood sampling process by simply hanging the livestock 39, stabbing the blood sampling knife 5, and lowering the livestock 39. It can be carried out efficiently, smoothly and quickly, and blood collection is not simply performed naturally from the livestock 39 as in the past.
That is, since the blood is collected from the blood collection knife 5 via the blood collection hose 8 into a predetermined blood collection tray 16 without dripping, blood does not flow out onto the floor of the slaughterhouse as in the conventional case. The sanitary aspect of the slaughterhouse can be greatly improved, and the occurrence of pollution caused by dripping of blood can be prevented.

Furthermore, by taking out the blood hygienically, other impurities are not mixed into the blood, making it possible to use the blood more effectively.Blood, which is an effective protein resource, can be widely used as feed, fertilizer, food additives, and medicines. In addition, since the effective use of blood eliminates the need to discharge blood as slaughter wastewater, the load on blood purification facilities can be reduced. The cost reduction involved and the scale of the purification facility will eliminate the previous situation where there was a restriction on the number of slaughtered animals.

Further, 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 does not have to manually add the anticoagulant solution each time the blood is collected. This is not necessary, and from this point of view as well, the efficiency of blood sampling work can be improved.

Furthermore, a device for supplying cleaning liquid to the blood sampling knife used for blood sampling and cleaning it is built into the blood sampling knife supporting and moving device, and automatically transfers the blood sampling knife to the blood sampling knife after blood sampling. Because the cleaning solution was supplied regularly,
This also eliminates the need for the operator to manually clean the blood sampling knife, thereby improving work efficiency.

In the above-mentioned embodiment, as shown in FIG. 5, the slope from point C to point D of the blood collection rail 30 is uphill, but instead of this, the annular shape of the blood collection rail 30 returning from point A to point A is All rails may be constructed with a downward slope.

In this case, the trolley 40 on which the livestock 39 is suspended at point A moves to point C, and further movement is restricted by locking the front end of the trolley 40 with the feed arm 2 in front of the trolley 40. Then, the feed arm 2 is moved at the rotational speed of the feed arm 2.

By setting the blood sampling position to point C' in the figure, the mortuary trolley 40 can be locked at point C', so the automatic stopper A232 can be omitted.
can also be omitted.

In this case, when the sensor A, 3 35 detects the trolley 40, it outputs a signal to activate the anticoagulant timer and the livestock feed timer, and the trolley 40 comes into contact with the forward feeding arm 2 at point C'. Livestock 3 at the time of locking
The blood sampling knife 5 is inserted into the animal 9, and when the work is completed, the livestock feed timer issues a signal to start the electric motor 24.

According to this configuration, as described above, the automatic stopper A2
There is an advantage that the structure of the sequence control device can be simplified, such as that 32 and the sensor shop 234 can be omitted.

7 In addition, in the above embodiment, the blood collection rail 30 is arranged in the three-dimensional movement range of the rotationally moving feed arm 2, and the trolley 40 on the blood collection rail 30 is pressed and moved by the feed arm 2. However, it is also possible to move the trolley by directly locking it to the feed arm, and this embodiment is shown in FIGS. 8 to 12.

Therefore, when the automatic stopper 66 is opened in response to a start signal from the sequence control device, 11 empty trolleys 58 pass through the automatic stopper 66 and reach the sensor 67, which sensor 67 detects the trolley 58 and immediately automatically When the stopper 66 closes, the sensor 67 activates the livestock feed timer.

As a result, 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.

Then, after a predetermined time, the livestock feeding timer starts the rotary pole electric motor, and the feeding arm 56 is moved to 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 piston rod 70A is actuated to pull the trolley 58 toward the front side, 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, the blood sampling knife 5 that had been stabbed into the livestock comes off like the old one.

The trolley 58 that has descended along the downwardly inclined blood collection rail 57B is loaded onto the blood collection rail 57A again by the trolley lift 65 after the livestock is removed at position B.

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.

Further, the anticoagulant solution supply device and the cleaning liquid 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 embodiment, there is no need to lift livestock suspended from a trolley to a high position and send it onto the blood collection rail, and the trolley lifter that performs this operation can be omitted. This has the advantage that it can be simplified and the manufacturing cost of the device can be reduced.

In each of the above-described embodiments, the blood sampling knife supporting and moving device is configured such that the blood sampling knife can be moved upwardly and downwardly using a pulley and a balance weight, but the pulley and balance weight are omitted. A structure in which a wire is simply connected to a hanging arm may be used, or the above-mentioned pulley, balance weight, and hanging arm may be omitted, and the blood sampling knife may be left hanging at all times.

In this case, the length of the wire must be set long enough to allow the blood sampling knife to be inserted into the livestock.

In addition, when a blood sampling knife is stuck in a livestock animal, the blood sampling knife is likely to fall out. Therefore, the blood sampling knife may be configured with a protrusion as shown in FIG. 15, for example, to prevent it from easily falling out from the livestock. Good.

Furthermore, the pulley, balance weight, wire, and hanging arm may be omitted, and the device for supporting and moving the blood sampling knife may simply include a rotating pole and a hose nozzle (protective cover).

However, in such a configuration, the blood sampling knife is not lifted up and held, and therefore moves along the floor surface when not in a blood sampling operation.

Therefore, since there is a risk of staining the floor surface with blood adhering to the blood sampling knife, a receiving tray for the blood sampling knife is provided in the area where the blood sampling knife moves, and the blood sampling knife is held on the tray and moved. It is better to do so.
