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 killed by the hammering method, and pigs are left unconscious by electrocution or gas slaughtering, and then left lying on their back by being stabbed in the throat with a stabbing blade 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 that relies entirely on natural exsanguination during slaughter is unhygienic as the blood drips onto the floor, etc., and now that pollution problems around slaughterhouses are increasing, It'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 to be 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, fertilizer, food additives, medicines, etc. This was a far cry from the current trend towards achieving this goal.

Therefore, in view of the above-mentioned conventional circumstances, the present invention is designed to hygienically collect blood from animals by directly collecting blood from the animal's body using a blood sampling knife tool that communicates with the blood collection section. The environment of the slaughterhouse can be improved, blood can be used effectively, and the burden on the slaughterhouse wastewater purification facility can be reduced.Furthermore, by installing a cleaning device for the blood sampling knife tool, workers can use the blood by hand. To provide an animal blood sampling device that can omit the work of cleaning a blood sampling knife and improves workability.

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. 5, 31 is the automatic stopper number.
1 and 32 are automatic stoppers No. 2, and livestock 3 respectively.
The purpose is to stop the trolley 40 on which the blood sample 9 is suspended at a predetermined position on the blood collection rail 30, and the trolley 40 is automatically opened and closed by a signal from the sequence control device.

Here, the automatic stopper No. 1 31 is used for the purpose of storing a predetermined number of livestock 39 at a predetermined position and sending out the trolleys 40 (livestock 39) to the blood collection site one by one, and the automatic stopper No. 2 32 is used for the purpose of storing a predetermined number of livestock 39 at a predetermined position and delivering the trolley 40 (livestock 39) to the blood collection location one by one. It is used to stop the livestock 39.

Numerals 33 to 36 are sensors No. 1 to No. 4 each composed of a phototube or a limit switch, etc., which detect the position of the trolley 40 sent onto the blood collection rail 30 and output a signal.

Sensor No. 1 33 is automatic stopper No. 1.
31, sensor No. 2 34 outputs a signal to operate an anticoagulant timer and a livestock feeding timer that control the opening and closing of the anticoagulant solution solenoid valve 12, which will be described later, and sensor No. 3 35 outputs a signal to operate an electric motor. Sensor No. 4 36 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 feed arm 2, pulleys 3A, 3B, hanging arm 4, blood sampling knife 5, balance weight 6, wire 7, blood sampling hose 8, protective cover 9, hose nozzle 10 , chamber 11, solenoid valve 12,
The control valve 13 and hose 14 are all rotated.

That is, the rotating pole 1 in the blood sampling knife support and movement device functions as a blood sampling conveyor that moves the blood sampling knife to the position of the livestock 39 suspended and supported by the hanging device via the feed arm 2. The livestock 39 is placed in a position corresponding to
When the blood sampling knife 5 reaches the blood sampling position, the blood sampling knife 5 is moved to the livestock 3.
9 and move almost synchronously 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 suspension chain 53 shown in FIG.
The point is engaged with the hook 54 on the trolley 40 on the trolley lift 50. 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 automatic stopper No. 1 31 in the closed state. In front of this automatic stopper No. 1 31, a plurality of trolleys 40 to which livestock 39 are connected by the above-mentioned operation remain.

When automatic stopper No. 1 31 is opened in response to a start signal from the sequence control device, one trolley 40 passes through automatic stopper No. 1 31 and moves toward automatic stopper No. 2 32. When the sensor No. 1 33 detects the trolley 40, the automatic stopper No. 1 31 immediately closes. As described above, only one trolley 40 is sent out. Next, the trolley 40 moves, and when sensor No. 2 34 detects this, the anticoagulant timer and the livestock feed timer of the sequence control device operate, and the anticoagulant timer operates the solenoid valve for the anticoagulant solution. 1
Let's open 2.

In addition, the anticoagulant timer is the solenoid valve 1 for anticoagulant solution.
The activated anticoagulant timer controls the electromagnetic valve 12 corresponding to the blood sampling knife 5 at position Z in FIG. 5.

Almost at the same time, the trolley 40 is stopped by automatic stopper No. 2 32.

Therefore, the operator pierces the livestock 39 with the blood sampling knife 5 at the Z position on the front side of the trolley 40 on which the livestock 39 is suspended. 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, the automatic stopper No. 2 32 is opened.

As described above, when the automatic stopper No. 2 32 is opened, the trolley 40 moves by its own weight to the position of the sensor No. 3 35 due to the downward slope of the blood collection rail 30B. This sensor No. 3 35 is the trolley 40
When this is detected, the automatic stopper No. 2 32 is closed, and the electric motor 24 shown in FIG. 2 is activated, the rotary pole 1 is driven to rotate, and the feed arm 2 is rotated as shown by the arrow in the figure.

The rotating feed arm 2 pushes the trolley 40 and moves it on the blood sampling rail 30B against the slope of the blood sampling rail 30B.

When the trolley 40 is detected by the sensor No. 4 36 on the blood collection rail 30B, the electric motor 24
turns OFF and stops operation.

One cycle of blood collection is completed in the above manner, but from now on, when the trolley 40 is automatically started, the above cycle is automatically repeated when the automatic stopper No. 1 31 of the next trolley 40 is opened.

In addition, when using single acting, a foot switch 29 is used, and 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 livestock 39 that has been subjected to the blood sampling process moves to point D shown in FIG. Since the blood sampling knife 5 that had been stuck into the livestock 39 tries to move along the rail 30B, the livestock 3
It naturally deviates from 9.

The detached blood sampling knife 5 is attached to the wire 7 shown in FIG.
It is supported in a lifted state by the holder, and then proceeds to the cleaning process.

And a hose nozzle 10 of the blood collection hose 8
is in contact with the cleaning liquid nozzle 23B (the fifth position)
When the position W is set at 60 degrees in the direction of movement from point D in the figure, this is detected by sensor No. 4 36, the solenoid valve 23C is opened, and the cleaning liquid is supplied to the hose nozzle 10, the blood collection hose 8, and the blood collection hose. Go up to knives 5 and clean them. In this case, the cleaning liquid that has risen to the hose nozzle 10, blood sampling hose 8, and blood sampling knife 5 passes through these and returns to the receiving tray 17, from where it is guided to the nozzle 20 by the guide plate 17A, and the cleaning liquid passes through the piping 21A. Return to tank 21. 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. And the sensor
When No. 4 36 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. The blood flows down into the tray 16, from where it passes through the nozzle 18 and into the blood tank 19 through the pipe 19A, where it is stored.

On the other hand, the blood collection rail 3 from point D to point E in Figure 5
The trolley 40, which has descended due to its own weight along the downward slope of 0B, lifts the trolley lift 51 at point E.
The sample is transferred to blood sampling rail 30A located at a lower position than blood sampling rail 30B. Here, the worker is Y
livestock 3 from the hook 54 of this trolley 40 at the position
The chain 53 connected to the farm animal 39 is removed 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 the livestock 39 is to be connected again.

In the embodiment described above, the blood sampling knife 5 and the blood sampling hose 8 constitute the blood sampling knife device according to the present invention, the cleaning liquid tank 21, the piping 23F, the pump 2
2. Piping 23A, solenoid valve 23C, nozzle 23B,
The receiving tray 17, the nozzle 20, the piping 21A, the minimum flow piping 23D, and the orifice 23E constitute the blood sampling knife cleaning device according to the present invention, and blood can be collected simply from the livestock 39 as in the conventional method.
In other words, the blood is received from the blood collection knife 5 through the blood collection hose 8 into the designated blood collection tray 16 instead of being allowed to naturally exsanguinate from the body, that is, the blood is received from the blood collection knife 5 through the blood collection hose 8 into a predetermined blood collection tray 16 without being allowed to drip out. There is no blood leakage, and the sanitary aspect of the slaughterhouse can be greatly improved, and the occurrence of pollution due to blood dripping can be prevented. Furthermore, by taking out the blood hygienically, other impurities are not mixed in with the blood, so the blood can be used effectively, and blood, which is an effective protein resource, can be used as feed, fertilizer, food additives, and medicines. This fully satisfies the recent desire for widespread use, and since the effective use of blood eliminates the need to discharge blood as slaughter wastewater, the load on blood purification facilities is reduced. This eliminates the previous situation where the number of slaughtered animals was limited due to cost reduction and the scale of the purification facility.

In addition, since a device is provided to supply and clean the blood sampling knife used for blood sampling, the blood sampling knife used for blood sampling can be made sanitary, and the blood sampling knife can be automatically sequentially removed. Can be washed cleanly,
It is possible to omit the work of manually cleaning the blood sampling knife by the operator, and it is possible to improve work efficiency.

According to this embodiment, as described above, the blood collection conveyor according to the present invention is connected by the feeding arm 2, the hanging device is connected by the blood collection rail 30 and the trolley 40, and the rotating pole 1 and the pulleys 3A, 3B are connected to each other. The hanging arm 4, the balance weight 6, the wire 7, and the hose nozzle 10 constitute a blood sampling knife supporting and moving device, and the livestock 3 to be blood sampled is
9 is suspended on the trolley 40 by the worker, it 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 blood sample 9 is suspended on the trolley 40. livestock 3
Since blood is continuously collected using the blood sampling knife tool that moves in synchronization with the movement of the blood sampling knife 9, the worker has to suspend the livestock 39 and lift the blood sampling knife 5 to a predetermined height. The piercing work and
There is an advantage that the blood collection work can be carried out extremely efficiently, smoothly and quickly just by carrying out the work of unloading the livestock 39.

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.

In the above-described embodiment, the slope from point C to point D of the blood collection rail 30 shown in FIG. may be constructed as all downward slopes.

In this case, the trolley 40 on which livestock 39 is suspended at point A moves to point C, and the feed arm 2 in front of the trolley 40 moves further.
The front end of the trolley 40 is locked and regulated, and the trolley 40 is moved at the rotational speed of the feed arm 2. By setting the blood sampling position at point C' in the figure, that is, because the trolley 40 can be locked at point C', the automatic stopper No. 2 32 can be omitted, and thereby the sensor No. 2 34 can also be omitted. .

In this case, when sensor No. 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 feed arm 2 located ahead of it at point C'. When the livestock 39 is stopped, the blood sampling knife 5 is stabbed into the livestock 39, and when the operation is completed, the livestock feed timer issues a signal to start the electric motor 24.

This configuration has the advantage that the structure of the sequence control device can be simplified, such as the automatic stopper No. 2 32 and sensor No. 2 34 being omitted as described above.

Further, in the above embodiment, the blood collection rail 30 is disposed within the three-dimensional movement range of the rotationally moving feed arm 2, and the trolley 40 on the blood collection rail 30 is pushed and moved by the feed arm 2.

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

The sensor indicated by 72 in the figure sends a signal to stop the rotary pole driving motor, a signal to open and close the cleaning liquid electromagnetic valve, a pull-out device 69, and an anticoagulant timer to open and close 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 C, or point D.

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

In FIG. 8, since the rail 57A is on a downward slope, the empty trolley 58 on the blood collection rail 57A descends along the rail 57A in the direction of the arrow in the figure, and reaches a plurality of reservoirs before the automatic stopper 66 in the closed state. It's on. On the other hand, since the rotary pole 59 is intermittently stopped from operating when the feed arm 56 comes to the sensor 72 position, each feed arm 56
When the tip reaches the D position, E position, A position, or C position, the feeding arm 56 stops, and at the C position, the tip of the blood collection rail 57A and the trolley support 61
The support rails 64 are in alignment with each other.

Therefore, when the automatic stopper 66 is opened by a start signal from the sequence control device, one empty trolley 58 passes through the automatic stopper 66 and reaches the sensor 67, and the sensor 67 detects the trolley 58. Immediately the automatic stopper 66 closes and the sensor 67 activates the livestock feed timer.

As a result, only one trolley 58 is sent out, and as shown in the figure, the trolley 58 rides on the support rail 64 and is held in the trolley storage space 62.

Then, after a predetermined time, the livestock feeding timer starts the electric motor for the rotary pole, and the feeding arm 5
6 moves intermittently to the D position, E 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 tip of the blood collection rail 57B matches the support rail 64 of the trolley support section 61 holding the livestock whose blood collection work has been completed while moving from the E position to the A position, and at this point the sensor 72
This signal causes the engagement portion at the tip of the piston rod 70A of the cylinder device 70 to engage the foot portion 58A of the trolley 58.
is engaged with the piston rod 70A to pull the trolley 58 toward you.
At the same time, the blood sampling knife 5 that has been stuck in the livestock is automatically removed.

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 set to the maximum time required for each operation at the A position, 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, the feed arm 56
Since the livestock are directly moved by the feed arm, there is no need to arrange the blood collection rail in the three-dimensional movement range of the feed arm as in the previous embodiment, and the construction work of the blood collection rail is simplified. At the same time, if the livestock is suspended on the trolley 58, the feed arm 56 will transport the livestock to the line at that position. Therefore, as in the previous embodiment, the livestock suspended on the trolley must be lifted to a high position and placed on the blood collection rail. There are advantages in that the hanging device consisting of the blood collection rail and the trolley can be simplified, such as the need to send the blood to the blood collection rail and the trolley, and the trolley lifter that performs this operation can be omitted, which is advantageous in terms of the manufacturing cost of the device.

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. However, the configuration may be such that the wire is simply connected to the hanging arm, 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. good. 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 into a livestock animal, the blood sampling knife tends to fall out. Therefore, it is preferable that the blood sampling knife is provided with a protrusion as shown in FIG. 15 to prevent it from easily falling out from the livestock. .

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 ball and a hose nozzle (protective cover). However, with this configuration, the blood sampling knife is not lifted and held;
When not collecting blood, move across the floor. 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. It is better to move it by moving it. It is convenient if this receiving tray also serves as a container 55 for receiving the cleaning liquid shown in FIG.

In addition, in the blood sampling knife cleaning device in each embodiment, the supply of cleaning liquid to the blood sampling knife is turned ON and OFF using a solenoid valve, but the electromagnetic valve can be omitted and the rotating pole can be directly controlled, such as by controlling the electric motor of the rotating pole. Of course, the electric motor of the pump may be turned on and off.
