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 abattoirs, the main method is to kill cattle using the beating method, while pigs are brought to a state of unconsciousness by electrocution or gas slaughter, and are left lying on their backs by stabbing their throats with a stab blade to die of natural exsanguination.

At that time, ``Blood discharged onto the floor etc. is introduced into a septic tank as slaughter wastewater along with washing water, and 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 problem of pollution around slaughterhouses is 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 circumstances, the present invention is designed to hygienically collect blood from an animal by directly collecting blood from the animal's body using a blood sampling knife tool that communicates with the blood collection section.
To improve the environment of the slaughterhouse, to make effective use of blood, and thereby to reduce the load on the slaughterhouse wastewater purification facility, and to provide a device that automatically adds an anticoagulant to the blood at the same time as blood collection. Accordingly, it is an object of the present invention to provide an animal blood sampling device that allows an operator to omit the work of manually adding an anticoagulant for each blood sampling operation, and improves workability.

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.
The hose nozzle 10 is arranged so that when it comes to a predetermined position by the rotation of the rotary pole, 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.

Also, 23D branches from the pipe 23A and connects to the cleaning liquid tank 2.

In other words, the cleaning liquid in the cleaning liquid tank 21 is transported by the hose nozzle 10 together with the rotating pole. When the hose nozzle 10 rotates and comes to face the nozzle 23B, the solenoid valve 23C opens, and the pump 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, 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 flows from the receiving tray 17 through the pipe 21A. The cleaning liquid is circulated back to the cleaning liquid tank 21 by gravity or a pump (not shown). The slip ring 26 is for supplying power to each solenoid valve 12 that rotates together with the rotating ball, and each in-machine wiring 28 from this slip ring 26 connects the shaft IA and the center of the rotating pole turtle to the in-machine piping. 27, and penetrates the outer peripheral wall of the rotary pole in front of the chamber 1, and is connected to each electromagnetic valve 12.

Reference numeral 29 is a foot switch for operating the above-mentioned machine body, and is used when the machine is operated in 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, automatic stoppers 31' and 32 are automatic stoppers No. 2, and their purpose is to stop the trolley 40 on which livestock 39 is suspended at a predetermined position on the blood collection rail 30," Automatically opens and closes based on signals from the sequence control device.

Here, "automatic stopper No. 131
is used to store the trolley 40 (livestock 39) at a predetermined position and send the trolley 40 (livestock 39) one by one to the blood sampling site, and the automatic stopper No. 232 is used to stop the livestock 39 at the blood sampling site.

33 to 36 are sensor numbers each composed of a phototube or a limit switch, etc. 1~No. At step 4, the position of the trolley 40 that is sent onto the blood sampling wheel 30 is detected and a signal is output.

And sensor NO. 133 is automatic stopper No. 13
1 and outputs a signal to close sensor NO. 234 outputs a signal to operate an anticoagulant timer and a livestock feeding timer that control the opening and closing of the anticoagulant solution electromagnetic valve 12, which will be described later, and the sensor N
O. 335 outputs a signal to start the electric motor 24, and sensor No. 335 outputs a signal to start the electric motor 24. 436 outputs a signal to stop the electric motor 24 and a signal to open and close the cleaning liquid electromagnetic valve 23C.

Here, rotating pole 1 is "by rotating"
Feeding 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 1
1. All of the solenoid valve 12, control valve 13, and hose 14 are rotated.

That is, the rotary pole 1 in the blood sampling knife support and movement device suspends the blood sampling knife and the anticoagulant supply device from the hanging device via the feeding arm 2, which serves as a blood sampling conveyor that moves the hanging device. The blood sampling knife 5 is stabbed into the livestock 39 from the time the livestock 39 comes to the blood collection position to a position corresponding to the position of the lowered and supported livestock 39, and is moved almost synchronously until the blood collection is completed.

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

At the x position in FIG. 5, the operator connects the pond end of the hanging chain 53 shown in FIG.
0 to the hook 54 on the trolley 401.

Next, when the trolley 40 with the livestock 39 coupled thereto is lifted up and transferred to the blood collection rail 30B located at a higher position than the blood collection rail 30A by operating the trolley lift 50, the trolley 401 is moved because the blood collection rail 30B is on a downward slope. The automatic stopper NO. 131 to stop. This automatic stopper No. A plurality of trolleys 40 with livestock 39 coupled thereto remain in front of the trolley 131 through the above-described operation.
Automatic stopper No. 1 is activated by the start signal from the sequence control device. 131 is opened, one trolley 40 moves to automatic stopper No. 131. 131 and automatic stopper No.
.

Move towards 232.

And sensor No. 133 detects the trolley 40, the automatic stopper No. 131 is closed. As described above, only one trolley 40 is sent out. Next, the trolley 40 moves and picks up the sensor No. 234
When detected, the anticoagulant timer and livestock feed timer of the sequence control device are activated, and the anticoagulant timer opens the anticoagulant solution electromagnetic 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 is moved to the automatic stopper No.
．． It stops at 232.

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 operation is completed, the automatic stopper No. 232 is opened. When the trolley 40 is opened, the trolley 40 moves by its own weight due to the downward slope of the blood collection rail 30B to the position of the sensor No. 335. When this sensor No. 335 detects the trolley 40, the automatic stopper No. 232 closes and the second The electric motor 24 shown in the figure is activated, the rotary pole is rotated, and the feed arm 2 is rotated as shown by the arrow in the figure.
It is moved on the blood sampling rail 30B against the gradient B. The trolley 40 is placed on the blood collection rail 30B with sensor No. When detected by 436, the electric motor 24 is turned off.
The operation will stop.

One cycle of blood collection is completed as described above, but from then on, when automatic startup is performed, the next trolley 40 is set to the automatic stopper No. 1
31 is opened, the above cycle is automatically repeated.

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 is set to the time required for blood collection depending on 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.
Since the blood sampling knife 5 tries to move along the blood sampling rail 30B with a downward slope after the point ○, it pierces the livestock 39, and the blood sampling knife 5 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 600 in the traveling direction from point D in FIG. 5), this is detected by sensor No. 436. Then, the solenoid valve 23C is opened, and the cleaning liquid rises to the hose nozzle 10, blood sampling hose 8, and blood sampling knife 5 to wash them.In this case, the cleaning liquid that has risen to the hose nozzle 10, blood sampling hose 8, and blood sampling knife 5 is It passes through these and returns to the receiving tray 17, and from here the nozzle 201 is guided by the guide plate 17A and returns to the cleaning liquid tank 21 through the piping 21A.
Set the supply pressure of the cleaning liquid to a high level and use the blood sampling knife 5 to collect the cleaning liquid.
Cleaning performance is better if the cleaning liquid is spouted from the tip, and in this case, a container 55 is provided to receive the cleaning liquid spouted from the blood sampling knife 5, as shown in FIG. And sensor No. 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 collection from the livestock 39 is carried out. 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, passes through the nozzle 18 and reaches the blood tank 19 through the piping 19A, where it is stocked.

On the other hand, the trolley 4, which has descended by its own weight along the downward slope of the blood collection rail 30B from point D to point B in Figure 5, is at point E.

The sample is moved by the Lee lift 51 to the blood collection rail 30A located at a lower position than the blood collection rail 30B. Here, the worker
At the Y position, the chain 53 connected to the livestock 39 is removed from the hook 54 of the trolley 40, and the livestock 39 is lowered. The empty trolley 4 moves by its own weight along the blood sampling rail 30A, which has a downward slope, and is loaded with livestock 3 again.
This leads to point A, where 9 should be connected. In the embodiment described above, the blood sampling knife device according to the present invention is constituted by the blood sampling knife 5 and the blood sampling hose 8. The anticoagulant supply device according to the present invention is constituted by the electromagnetic valve 12, the hose 14, and the flow control valve 13 for the anticoagulant solution. The blood sampling knife supporting and moving device according to the present invention is constituted by the hose nozzle 10 and the blood sampling knife supporting and moving device according to the present invention. When the worker suspends the livestock 39, the blood sampling knife 5 is raised to a predetermined height.
The blood collection work can be carried out extremely efficiently, smoothly and quickly by simply piercing the animal and lowering the livestock 39. In addition, the blood collection can be performed by simply letting the livestock 39 bleed naturally as in the past. In other words, since blood is received from the blood collection knife 5 through the blood collection hose 8 into the designated collection tray 6 without dripping, blood does not flow out onto the floor of the slaughterhouse like in the case of a secondary tank. Without,
It is possible to improve the sanitary aspect of the slaughterhouse, and also to prevent the occurrence of pollution caused by blood dripping.

Furthermore, by removing blood hygienically, "other impurities are not mixed into the blood, so blood can be used effectively, and 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. This reduces costs and eliminates the previous situation where the number of animals slaughtered was restricted due to the scale of the purification facility.In addition, a device was installed that automatically added an anticoagulant solution to the blood at the same time as blood collection. It is not necessary for the operator to manually add an anticoagulant solution for each blood collection operation, and from this point of view, the efficiency of the blood collection operation can be improved.

Furthermore, according to this embodiment, a device for supplying a cleaning liquid to the blood sampling knife used for blood sampling and cleaning it is incorporated into the blood sampling knife supporting and moving device, and the blood sampling after blood sampling is performed. Since the cleaning liquid is automatically supplied to the knife tool in sequence, the operator also has to do it manually.
The work of cleaning the blood sampling knife can be omitted, and workability 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 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, It is made to move at the rotational movement speed of the feed arm 2.

Then, by setting the blood sampling position to point C' in the figure,
That is, since the trolley 40 can be locked at point ○, automatic stopper No. 232 can be omitted, which allows sensor NO. 2
34 can also be omitted. In this case, sensor NO. When the trolley 335 detects the trolley 40, it outputs a signal to activate the anticoagulant timer and the livestock feeding timer, and when the trolley 40 is latched to the feeding arm 2 located ahead of this at point ○, blood is collected from the livestock 39. All that is required is for the livestock feeding timer to output a signal to start the electric motor 24 when the knife 5 is stabbed and the operation is completed.

According to this configuration, as described above, the automatic stopper NO.
232 and sensor NO. 234 can be omitted, and the structure of the sequence control device can be simplified.

Furthermore, in the above embodiment, the rotating feed arm 2
A blood collection rail 30 is disposed in a three-dimensional movement range, and a trolley 40 on the blood collection rail 30 is pushed and moved by the feed arm 2, but the trolley is directly locked to this feed arm. It may be moved, and this embodiment is shown in FIGS. 8 to 12.

That is, in FIG. 8, the feed arm 56 as a blood collection conveyor in this embodiment is configured to directly move the trolley 58 (see FIG. 11) from the blood collection rail 57A.

This configuration includes a support rail 64 that extends and projects. Note that the support rail 64 is a rotating pole 59.
It is slanted downward in the direction. The blood collection rail 57 shown in FIG. 8 is formed as a rail from point A at the tip of one feed arm 56, passing through point B and ending at point C at an angle of 450 degrees clockwise from the feed arm 56, as shown in the figure. and A
The blood collection rail 57B from point B to point B has a downward slope, and the blood collection rail 57A going from the trolley lift 65 provided at point B to point C descends from a position higher than the point A at point B to point C. A slope is attached. Here, "point C" is the point at which a large number of empty trolleys 58 suspended and supported between the point B and the point C on the blood collection rail 57 are supported by the trolley support part 61 at the tip of the feeding arm 56, and the automatic stopper 66 This automatic stopper 66G stores a predetermined number of empty trolleys 58 at a predetermined position, and sends out the trolleys 68 one by one to the trolley support portion 61 at the tip of the feed arm 56. Automatically opens and closes depending on the signal from the sequence control device.Sensor 6
7 outputs a signal for closing the automatic stopper 66 and a signal for activating the livestock feeding timer for starting the electric motor for driving the rotary pole. Point D is a place where the livestock is suspended from the trolley 58 at the tip of the feeding arm 56, and is provided with a chute 68 through which the livestock is fed from a high position.

Point E is the place where blood sampling work is performed.

At point A, the trolley 58 on which the livestock is suspended, which is supported at the tip of the feed arm 56, is pulled out from the trolley support section 61 at the tip of the feed arm 56 and transferred to the blood collection rail 57B.
This is the place where the trolley 58 is moved, and is equipped with a pull-out device 69 for pulling out the trolley 58.

This pull-out device 69 is composed of a cylinder device 701 having an engagement portion at the tip of a piston rod 70A that can be freely engaged with and detached from the foot portion 58A of the trolley 58 shown in FIGS. 11 and 12. Point B is a place where the livestock is removed from the trolley 58 that has been pulled out from point A onto the blood collection rail 57B and has descended to a low position along the blood collection rail 57B, and is equipped with a roller conveyor 71 and the like. Also, ``At this point B, the empty trolley 58 from which livestock has been removed is moved to the trolley lift 65.
This is also the place where blood is placed on the blood collection rail 57A located on the higher floor using the blood collection rail 57A.

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. It is a device that issues a signal for actuation, 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 has a downward slope, the empty trolley 58 on the blood collection rail 57A moves in the direction of the arrow in the figure, descends along the rail 57A, and reaches several points in front of the automatic stopper 66 in the closed state. It's accumulating.

On the other hand, the rotating pole 59 has the feed arm 56 connected to the sensor 72.
Since the operation is intermittently stopped by reaching the position, the tip of each feed arm 56 is at the D position, E position, A position,
When reaching the C position, the feed arm 56 stops, and at the C position, the tip of the blood collection rail 57A and the trolley support 6
The support rail 64 of No. 1 is in alignment with the support rail 64 of No. 1. Therefore, when the automatic stopper 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 61', the sensor 67 detects the trolley 58, and immediately When the automatic 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.

After a predetermined period of 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 tip of the blood collection rail 578 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 In response to the signal, the engaging portion at the tip of the piston rod 78A of the cylinder device 70 is engaged with the foot portion 58A of the trolley 58, and the piston rod 70A is actuated to pull the trolley 58 toward you,
As the trolley 58 is moved from the rail 64 of the trolley support section 61 to the blood sampling rail 57B side, the blood sampling knife 5 that was shaving the livestock comes off naturally. Trolley 5 descending along the downhill blood collection rail 57B
8 is placed on the blood collection rail 57A again by the trolley lift 65 after the livestock is removed at the B position. 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, 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. Take the trouble to lift it to a high position,
There is no need to feed the blood onto the blood collection rail, the trolley lifter that performs this operation can be omitted, and the hanging device consisting of the blood collection rail and trolley can be simplified, which is advantageous in terms of 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. 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 kept hanging down 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, it is easy for the blood sampling knife to fall out, so it is recommended that the blood sampling knife be configured with a protrusion, for example, as shown in Figure 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 include only a rotating pole and a hose/spool (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. It is convenient if this receiving tray also serves as a container 55 for receiving the cleaning liquid shown in FIG. 13 and 14 show still another embodiment of the present invention.
