Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blood sampling device for collecting blood from animals such as livestock such as cows and pigs during slaughter, and more particularly to a support device for a blood sampling knife.

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 the blood that is dripped in this way 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 a purification facility. 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.

For this reason, a method has been considered in which blood is directly collected from the animal's body by piercing the animal with a blood sampling knife having a blade at the tip of a pipe body leading to a blood collection section.

In a blood sampling device equipped with such a blood sampling knife, if the blood sampling knife is simply suspended from above or is held in a state where it hangs down on the floor, The following disadvantages arise.

That is, at times other than when blood is being collected, blood and the like adhering to the blood collecting knife drips onto the floor, staining the floor, which is undesirable from a sanitary standpoint.

In addition, in a structure in which a blood sampling knife is pierced into an animal that is suspended and supported, if the blood sampling knife is pierced into the animal and then released, the blood sampling knife may fall off from the animal. If the blood sampling knife is held hanging on the floor, the tedious work of unrolling the blood sampling knife from the floor and lifting it to the level of the suspended animal is required. It could not be said that it was good in terms of use and work.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional circumstances, the present invention provides a blood sampling apparatus equipped with a blood sampling knife, which is configured to hold the blood sampling knife in an upwardly pulled state at all times, so that the blood sampling knife can be removed at times other than blood sampling. This eliminates the above-mentioned drawbacks of the conventional method, such as preventing blood etc. attached to the device from dripping onto the floor, and preventing the blood sampling knife device from falling out of the animal when it is pierced into a suspended animal. The present invention provides a blood sampling knife support device that is advantageous in terms of use and work, and furthermore, the position at which the blood sampling knife is inserted can be changed according to the size of the suspended and supported animal. be.

It penetrates the outer peripheral wall of the rotating pole 1 and is connected to each electromagnetic valve 12.

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 an automatic stopper.
No. 1 and 32 are automatic stopper No. 2, and each trolley 40 with livestock 39 suspended thereon is moved to the blood collection rail 3.
Its purpose is to stop at a predetermined position above zero, and it opens and closes automatically according to a signal from the sequence control device.

Here, the automatic stopper No. 1 is the predetermined number of livestock 3.
Automatic stopper No. 2 32 is used to stop the livestock 39 at the blood sampling location.

Sensors No. 1 to No. 4 33 to 36 each include a phototube or a limit switch, and 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 and sends a signal to close sensor No. 2 34.
Sensor No. 3 35 outputs a signal to start the electric motor 24, and sensor No. 4 36 outputs a signal to start the electric motor 24. A signal to stop the conductor 24 and a signal to open and close the cleaning electromagnetic valve 23C are issued.

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, a rotary pole 1 serving as a blood sampling knife moving device suspends the blood sampling knife supporting device and the blood sampling knife on a hanging device via a feed arm 2 serving as a blood sampling conveyor that moves the hanging device. The blood sampling knife 5 is moved almost synchronously to a position corresponding to the position of the livestock 39 supported by the lowered animal from when the livestock 39 comes to the blood collection position until the blood collection is completed by piercing the livestock 39 into the livestock 39.

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

At position X in FIG. 5, the operator attaches 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 the 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. Then, as soon as sensor No. 1 33 detects the trolley 40, automatic stopper No. 1 3
1 is closed. With the 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 feeding timer of the sequence control device are activated, and the anticoagulant timer is activated by the solenoid valve for the anticoagulant solution. Let's open 12.

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 feed 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. When this sensor No. 3 35 detects the trolley 40, the automatic stopper No. 2 32 closes and the electric motor 24 shown in FIG.
rotates as shown by the arrow.

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 sensor No. 4 36 on the blood collection rail 30B, the electric motor 2
4 turns OFF and stops operation.

One cycle of blood collection is completed in the above manner, but thereafter, 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 supported in a lifted state by the wire 7 shown in FIG. 1, and proceeds to the cleaning step.

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 collection hose 8, and blood collection knife 5 passes through these and returns to the receiving tray 17, from where it is directed to the nozzle 20 by 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 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.

According to the blood sampling knife support device in the blood sampling apparatus configured as above, a string material for hanging the blood sampling knife, such as the wire 7, whose one end is connected to the blood sampling knife, and a pulley 3A for hooking the string material; A blood sampling knife hanging body such as a hanging arm 4 having a hanging part such as 3B is connected to the other end of the string material to constantly pull the blood sampling knife upward and to the upper and lower positions of the blood sampling knife. Since the structure is equipped with a balance weight 6 that can be balanced and moved up and down depending on the situation, the blood sampling knife tool can be lifted and supported while always being positioned at a predetermined height, and the blood sampling knife 5 can be suspended and supported on the animal. Even if I let go of my hand after stabbing it,
The blood sampling knife 5 does not fall out from the animal, and the blood sampling knife is always kept hanging down on the floor, so that the blood sampling knife 5 cannot be picked up from the floor when blood is collected. There is no need to carry the blood sampling knife 5 to the animal position, and since the blood sampling knife 5 is not placed on the floor when it is not used for blood sampling, blood etc. adhering to the blood sampling knife 5 can be removed from the floor. It does not stain the surface, which is advantageous in terms of work surface and hygiene.

Furthermore, since the blood sampling knife tool is not only suspended upward, but can also be balanced with the balance weight 6 to adjust its height as appropriate, it is possible to adjust the height of the blood sampling knife according to the size of the suspended animal, that is, the state in which the animal is suspended. It has the advantage that it can easily accommodate different lengths.

In the embodiment described above, as described above, the feeding arm 2 serves as a blood collection conveyor, the blood collection rail 30 and trolley 40 provide a hanging device, and the blood collection knife 5 and blood collection hose 8 provide a blood collection knife tool. The rotating pole 1 constitutes a blood sampling knife moving device, and the livestock 3 whose blood is to be 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
The blood collection work can be carried out extremely efficiently, smoothly and quickly just by unloading the livestock 39, and blood collection is not simply done by letting the livestock 39 naturally exsanguinate as in the past, that is, Since the blood is received from the blood collection knife 5 through the blood collection hose 8 into the designated blood collection tray 16 without dripping, blood does not flow out onto the floor of the slaughterhouse as in the past, which improves the hygiene of the slaughterhouse. It is possible to greatly improve the quality of the blood, and also to prevent the occurrence of pollution due to blood dripping. Furthermore, by taking out the blood hygienically, other impurities in the blood are not mixed in, so the blood can be used effectively, and the blood can be used as an effective protein resource for feed, fertilizer, food additives, and medicine. 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 method has the advantage of cost reduction and the fact that the number of animals to be slaughtered is not limited by the scale of the purification facility.

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 and cleaning the blood sampling knife used for blood collection with a cleaning liquid is incorporated into the blood sampling knife moving device, and the cleaning liquid is automatically supplied to the blood sampling knife used to collect blood one after another. This also has the advantage that the operator does not have to manually clean the blood sampling knife, thereby improving work efficiency.

Fixedly attached to 05. A pinion gear 106 is connected to the tip of this support shaft 105, and when this pinion gear 106 meshes with a rack (not shown) located at the blood collection tray 104 position within its movement range, it is rotated and supported. Place the blood receiving cup 103 above the blood collection tray 104 via the shaft 105.
Flip 180.

Therefore, the blood in the blood receiving cup 103 is drained into the blood collection tray 104. At a position where the blood receiving cup 103 has passed a washing liquid receiving tray 110 after the washing liquid has been supplied, which will be described later, the pinion gear 106 is rotated by a rack (not shown), so that the blood receiving cup 103 is turned back to its original position.

The blood collection tray 104 is led to a blood collection tank (not shown) via a pipe 123.

Reference numeral 107 denotes a receiving cup for an anticoagulant solution, and when each blood collection unit 89 enters the blood collection process, a predetermined amount of anticoagulant solution is supplied via a piping 108 that is pumped by a pump (not shown). The solution from 107 passes through the flow rate control valve 109A and the hose 109B so that an appropriate amount of the solution is delivered to the blood sampling knife 8 during blood collection.
8A.

The washing liquid receiving tray 110 is arranged at a position behind the blood collecting tray 104 through which the blood collecting unit 89 passes. 111 is a cleaning liquid supply pipe led from a cleaning liquid tank (not shown) via a cleaning liquid supply pump, and is branched just before the cleaning liquid receiving tray 110, and one branched cleaning liquid supply pipe 111A
When the hose nozzle 112 of each blood sampling unit 89 is located above the receiving tray 110, it faces the opening at the tip of the hose nozzle 112 and squirts cleaning liquid from the hose nozzle 112 to the blood sampling knife 88A. I'm starting to do that. The other branched cleaning liquid supply pipe 111B is
When the inverted blood receiving cup 103 of each blood collecting unit 89 comes to the upper position in the washing liquid receiving tray 110, it faces the opening of the blood receiving cup 103 and the washing liquid is spouted into the blood receiving cup 103. ing. Reference numerals 111C and 111D indicate electromagnetic valves installed in the cleaning liquid supply pipes 111A and 111B, respectively, which are opened when the blood collection unit 89 comes to the cleaning position by a sensor (not shown).

A cleaning liquid recovery pipe 113 is connected to the other side of the receiving tray 110, and collects the cleaning liquid received in the receiving tray 110 into the cleaning liquid tank.

In this configuration, each blood sampling unit 89 moves synchronously to a position corresponding to each hanging position of the livestock moved by the chain conveyor 73,
Blood is collected between C and D in the figure. This synchronous movement is performed by the rotational drive shaft 11 of the chain conveyor 73.
2 and the rotational drive shaft 78 of the blood sampling knife moving device 74.
This can be achieved by mechanical synchronization means that interlocks the blood collection knife and the like with a chain or the like, or by providing a new drive source in the chain conveyor 73 and providing an electrical means such as a rotation control device between it and the drive source of the blood sampling knife moving device 74. Ru.

The position where the operator pierces the livestock 77 with the blood sampling knife 88A is point E in the figure.

In the blood sampling knife support device having such a structure, as in the previous embodiment, it is possible to improve the working surface and the sanitary aspect in the process of piercing the blood sampling knife into the animal.

Further, in this embodiment, the worker who stabs the blood sampling knife 88A into the livestock 77 as described above is located at the position where the blood sampling knife 88A is moving, but the hanging arm 94 falls upward. ,
As a result of the configuration in which the blood sampling knife 88A moves close to the blood sampling unit main body 90, the blood sampling knife 88
There is no danger of A hitting the worker, and there is an advantage that the chain conveyor 73 and the blood sampling knife moving device can be operated synchronously at a constant speed without the need to temporarily stop the chain conveyor 73 and the blood sampling knife moving device for blood sampling work.

As explained above, the present invention provides a blood sampling knife hanging body comprising a string material for hanging a blood sampling knife whose one end is connected to a blood sampling knife, a hanging portion for attracting the string material, and a blood sampling knife hanging body that includes a string material for hanging a blood sampling knife whose one end is connected to a blood sampling knife. By providing a blood sampling knife support device including a balance weight connected to an end of the blood sampling knife to constantly pull the blood sampling knife upward and change the vertical position in a balanced manner according to the vertical position of the blood sampling knife. Since the blood sampling knife can be pulled up at all times and the vertical position of the blood sampling knife can be adjusted, it is effective in preventing the blood sampling knife from falling off from the animal during blood sampling, improves workability in operating the blood sampling knife, and improves the ability to remove blood from the blood sampling knife. Hygiene can be improved by preventing blood etc. from falling, and usability can be improved by being able to change the piercing position of the blood sampling knife depending on the size of the animal.
