Description

  The present invention relates to a device for anesthesia treatment of slaughter animals.

  Traditionally, as the method of slaughtering meat animals, the electric shock method has been used, but the anesthesia method is overwhelming for various problems such as blood release and blood collection methods, work efficiency, work load, and carcass finish quality. Is excellent.

  As an anesthesia method, an anesthesia apparatus as shown in FIG. 10 was used. The anesthesia apparatus is provided with an anesthesia tank provided with an entrance of an animal, a drive source attached to the anesthesia tank, a rotation source configured to rotate within the anesthesia tank, and a plurality of the anesthesia apparatus having a required interval. And a plurality of guide members that mesh with the rope member, and a support device that is provided near the entrance of the anesthesia tank and temporarily holds an animal entering the anesthesia tank. Further, the guide member is composed of an up / down guide member and a down / up guide member provided in parallel with the up / down guide member. Since this anesthesia apparatus can move a plurality of animals into the anesthesia tank, it has an advantage of high anesthesia processing capability.

  However, in this anesthesia apparatus, the animal placed on the gondola from the entrance immediately descends to the bottom of the anesthesia tank, causing a problem that the animal is deficient in oxygen and dyspnea. An animal that has fallen into this state has broken capillaries in the body, leading to congestion in the carcass, liver, heart, and the like. As a result, there has been a problem that the taste of the meat has fallen or the quality has deteriorated. In meat distribution, transactions are basically made in the raw state, so if congested conditions occur in the carcass, liver, heart, etc., the product value will be significantly impaired, and the food safety and the reliability of the traders will be reduced. There was also a risk of adversely affecting the product.

In order to solve this problem, in the invention described in Japanese Patent Publication No. 1-20841, in a carbon dioxide gas anesthesia tank, a plurality of gondola fixedly supporting an animal rotate in a gondola shape to An anesthesia method for slaughter animals is disclosed. According to the present invention, a gondola that fixedly supports an animal is lowered in stages through a plurality of lowering guide members. As a result, it is possible to gradually anesthetize the animal and to prevent the animal from lacking oxygen, difficulty breathing, and the like.

  However, the anesthesia apparatus described in Japanese Examined Patent Publication No. 1-20841 has a structure in which a gondola moves laterally in the anesthetic tank. Since a plurality of gondola are provided in the anesthesia tank, the state where the gondola is positioned up and down in the anesthesia tank occurs. For this reason, there has been a problem that the excrement of the animal in the upper gondola is contaminated by the lower gondola and the animal. In particular, since it relates to food, it is not preferable that filth adheres to animals from the viewpoint of hygiene. For this reason, the contaminated animal has to be washed before and after blood collection and exsanguination, resulting in a problem of poor work efficiency. In addition, the gondola covered with filth had to be cleaned, which had the problem that the work was difficult.

  In addition, since the gondola moves laterally in the anesthetic tank as described above, the anesthetic tank spreads sideways and tends to have a large capacity. As a result, there is a problem that the amount of gas necessary for filling the anesthesia tank increases and the maintenance cost tends to increase. In addition, a large-scale anesthesia apparatus has a high installation cost and has a problem that it cannot be easily installed.

  In addition, since a conventional gondola has an open entrance for animals, for example, when anesthesia is performed with two animals guided in the gondola, the animals in the front and back struggle with each other and the animals in the back are pushed out. There was a risk of falling off the gondola. In addition, when an animal falls off from the gondola, the anesthesia apparatus has to be temporarily stopped, and there is a problem that productivity is very poor.

  From the above, it is possible to prevent the animal from deficient oxygen / dyspnea, without impairing the anesthesia treatment ability, and even if the animal is excreted in the anesthesia tank, other gondola and animals are not contaminated. Therefore, there has been a demand for the development of an anesthesia apparatus that can reduce the installation cost, manufacturing cost, and maintenance cost of the anesthesia apparatus.

FIG. 1 is an explanatory view showing an anesthesia apparatus 2 according to the present invention, and FIG. 2 is a plan view showing the anesthesia apparatus 2 according to the present invention. In FIG. 2, the elevator 12 is omitted for explanation. 3 is a partial cross-sectional view showing from the carry-in port 30 side in FIG. 2, and FIG. 4 is a partial cross-sectional view showing from the carry-out port 34 side in FIG. 3 and 4 use one gondola 6 for convenience of explanation. Further, these drawings are only for explaining the present invention and do not limit the present invention. Moreover, although the animal used in this text mainly refers to pigs, it may be other livestock animals such as cows.

  The animal anesthesia apparatus 2 according to the present invention includes a cylindrical anesthesia tank 4 and a moving apparatus for moving the animal in the anesthesia tank 4. Since the anesthesia apparatus 2 according to the present invention has a structure in which the gondola 6 is rotated about the column 24, as shown in FIG. Omitting and trying to miniaturize the anesthesia apparatus 2. Further, by saving the space of the anesthetic tank 4, the amount of gas used can be reduced, which can greatly contribute to cost reduction. In FIG. 1, the bottom of the anesthesia tank 4 is shown flat, but an appropriate slope may be provided for draining the washing water and the like. An exhaust pipe for discharging gas, a water distribution pipe for discharging washing water that has washed the anesthesia tank 4, the gondola 6, and other devices may be appropriately installed.

  Next, the moving device includes a gondola 6 that fixes and supports an animal, and moving means that moves the gondola 6 according to a predetermined route in the anesthesia tank 4. The gondola 6 according to the present invention includes an inner gondola 10 that supports and fixes an animal, and an outer gondola 8 that loads and holds the inner gondola 10. The loading and holding of the inner gondola 10 refers to a state in which the inner gondola 10 is removable from the outer gondola 8 or a state in which the inner gondola 10 is movable while being connected to a part of the outer gondola 8. It is further preferable that the outer gondola 8 holds the inner gondola 10 so as not to move when the animal is anesthetized, and the inner gondola 10 can move when the animal is carried out. As a method of moving the inner gondola 10, for example, a connecting portion between the inner gondola 10 and the outer gondola 8 may be used as a rotation axis, and the inner gondola 10 may be rotated around the rotation axis. It is further preferable that the hook provided on the outer gondola 8 is engaged with the end of the inner gondola 10 and the hook is removed only when the gondola 6 reaches a predetermined position. The moving method of the inner gondola 10 may be other than these methods, and may be set as appropriate in consideration of the loading method, loading structure, etc. of the outer gondola 8.

  The shape of the inner gondola 10 is not particularly limited as long as the animal can be fixedly supported. However, in consideration of conditions such as the efficiency of guiding the animal to the gondola 6 and the fixation and holding of the animal, the shape of the inner gondola 10 is substantially cylindrical or saddle-shaped. Is good. The inner gondola 10 according to the present invention is a substantially cylindrical body having an opening for entering an animal, a pair of holding side surfaces provided orthogonal to the opening, and a connecting member for connecting the holding side surfaces. Yes. Moreover, the bottom part of the inner gondola 10 is formed in a bottomed shape. The bottom of the inner gondola 10 has a width that prevents the animal from falling, and the leg of the animal protrudes from the bottom of the bottom, and the edge of the holding side surface is further locked to the animal's trunk. Further, the pair of holding side surfaces are provided to face each other, and are preferably formed in a curved shape toward the bottom side of the inner gondola 10 so as to easily hold the animal torso. The reason why the inner gondola 10 is in the bottom shape is that if there is an animal scaffold when the animal is transported or anesthetized with the gondola 6, it may jump out of the gondola 6 or drop, so the animal scaffold is lost. By holding the animal's torso and putting it in a suspended state, it is intended to prevent the animal from jumping out or falling from the gondola 6 even if the animal goes wild. Furthermore, during the movement of the gondola 6 or during anesthesia, the animal may be excited or the muscle may be loosened and excreted by anesthesia. At this time, if the gondola 6 is in a bottom shape, there is an advantage that excrement falls from the gondola 6 and the inside of the gondola 6 does not become dirty. Further, the outer gondola 8 may have any shape and structure as long as the inner gondola 10 can be loaded and held. For example, a plurality of pipes may be combined in a lattice shape or a box shape. It may be set as appropriate in consideration of conditions such as the loading method and the loading structure.

  Moreover, the anesthesia apparatus 2 according to the present invention may be provided with an auxiliary bottom portion 42 that closes the bottom missing portion of the inner gondola 10. Further, the auxiliary bottom portion 42 may be movable as shown in FIG. In the gondola 6 according to the present invention, as described above, the inner gondola 10 has a bottomed shape. Therefore, when the animal is guided into the gondola 6, the animal is unlikely to enter the inner gondola 10 because there is no animal scaffolding. The problem will arise. Therefore, the bottom of the inner gondola 10 is closed by the auxiliary bottom portion 42, and an animal scaffolding is temporarily provided to improve guidance efficiency. However, if there is an animal scaffold during movement of the gondola 6 or during anesthesia, the animal may run wild or jump out of the gondola 6. Therefore, the auxiliary bottom 42 is made movable, and the inner gondola is moved when the gondola 6 is moved or anesthetized. It is intended to make 10 a bottom-out shape. About the installation location of this auxiliary | assistant bottom part 42, you may provide in the gondola 6 and may provide in the gondola 6 outside. In FIG. 1, the auxiliary bottom 42 is shown in the air. However, this is for convenience of explanation, and in the present invention, a rotating shaft is connected and fixed to a side surface of a casing 28 described later, and the auxiliary bottom 42 is held. Yes. If the auxiliary bottom portion 42 is provided so as to be able to block the bottom missing portion of the inner gondola 10 when the animal is loaded with the gondola 6 and to be moved to a location that does not contact the gondola 6 when the gondola 6 is moved and lifted, What is necessary is just to set suitably about an installation location, a structure, a form, etc.

  The moving means according to the present invention includes a support column 24 provided at the center of the anesthesia tank 4, an elevator 12 that moves the gondola 6 up and down in the anesthesia tank 4, and a rotating machine 26 that rotates the support column 24. . For convenience of explanation, the support 24 is used. However, a member or a part that is located in the center of the anesthetic tank 4 and is provided with the elevator 12 and rotated by the rotating machine 26 is referred to as a support 24. Although a columnar or prismatic member may be used as the support 24, for example, a part of the elevator 12 may be used as the support 24, and a part of the rotating machine 26 may be used as the support 24. Further, a combination of these or a plurality of members may be used as the support column 24. Regarding the form, structure, shape, and the like of the support column 24, the structure and means of the rotating machine 26, the rotation method of the support column 24, the structure and means of the elevator 12 It may be set as appropriate in consideration of various conditions such as the above.

  Further, the rotating machine 26 according to the present invention may have any structure / means as long as the column 24 can be rotated. The rotating machine 26 shown in FIGS. 1 to 4 is provided with a rotating table at the bottom of the anesthesia tank 4, a column 24 is provided on the rotating table, and the rotating means and the column 24 are connected to each other. The support 24 is rotated by moving the rotating means on the step. The structure of the rotating machine 26 according to the present invention is such that the elevator 12 according to the present invention suspends and raises the gondola 6 as will be described later. Sometimes the support 24 may vibrate. In view of this, the support that connects the rotating means and the support column 24 supports the middle portion of the support column 24 to prevent vibration of the support column 24. In addition to this structure, for example, a rotating machine 26 may be provided on the bottom or top side of the support 24 to rotate the support 24, and the structure and means of the rotating machine 26, the structure and means of the elevator 12, etc. Set it.

  Further, as the elevator 12 according to the present invention, any means and device can be used as long as the gondola 6 can be moved up and down in the anesthetic tank 4 and the gondola 6 can be stopped and held at an arbitrary height position. It may be. The elevator 12 shown in FIG. 1 includes an upper pulley 14 provided in the vicinity of the top of the support 24, a lower pulley 16 provided in the vicinity of the support bottom, and a top 24 of the support 24 via the upper pulley 14 and the lower pulley 16. It comprises a suspension chain 18 for raising and lowering the gondola 6 and a drive source (not shown) for sliding the suspension chain 18. The elevator 12 may be provided with an auxiliary member for preventing the gondola 6 from shaking and vibrating. The auxiliary member shown in FIG. 1 is provided with a guide rail 20 on the side surface of the column 24 and a guide wheel 22 that moves along the guide rail 20 on the side surface of the gondola 6. In addition to this, for example, a protrusion may be provided on the side surface of the gondola 6, a groove may be provided on the side surface of the support column 24, and the protrusion and the groove may be fitted and engaged to serve as an auxiliary member. What is necessary is just to set suitably considering conditions, such as the shape and structure of the gondola 6, the elevator 12, and the support | pillar 24, the form and structure of the elevator 12, and the raising / lowering method.

  Further, as shown in FIG. 1, the elevator 12 and the gondola 6 are preferably provided in a pair. It should be noted that the elevator 12 and the gondola 6 are provided in a pair as one means or device for moving the gondola 6 up and down with respect to one gondola 6 is provided without being linked to other gondola 6. It refers to the state that can move independently.

  Further, as shown in FIG. 2, the anesthesia tank 4 is provided with a carry-in port 30 for carrying the animal into the gondola 6 and a carry-out port 34 for carrying the animal out of the gondola 6. With regard to the carry-in entrance 30 and the carry-out exit 34, the place where the animal is simply carried into the gondola 6 may be the carry-in entrance 30 and the place where the animal is carried out from the gondola 6 may be the carry-out exit 34. It may be provided. For example, a loading door 32 that can guide a plurality of animals into the gondola for every predetermined number of animals may be provided at the carry-in entrance 30. This is because when an animal is carried into the gondola 6, the animal may be rampant or disliked, so that it may not be carried in smoothly. Therefore, an additional door 32 is provided at the carry-in entrance 30 and is guided into the gondola 6 every predetermined number of heads to improve the guidance efficiency. The specific shape and structure of the additional door 32 are not particularly limited. For example, a passage having a width that allows only one animal to pass therethrough is provided, and a gate that prevents the animal from running backward is provided in the passage. Also good.

  Further, as shown in FIGS. 1 to 3, the carry-out port 34 may be provided with a carry-out stand 36 for carrying out the animals in the gondola 6. The carry-out table 36 includes a low friction surface having a smooth surface. As shown in FIG. 1 or FIG. 3, the low-friction surface is inclined at a predetermined angle so that the animal can easily slide on the surface. Further, a stopper may be provided to prevent the animal that has moved on the low friction surface from jumping out from the carry-out table 36. In FIG. 1, the low friction surface is curved and the end is used as a stopper. Further, a reversing member may be provided on the low friction surface. The reversing member is a member for reversing the animal posture on the low friction surface. This is because when the animal carried out from the gondola 6 is carried out with the back facing the operator, the next work becomes very troublesome. After the anesthesia treatment, the animal must be transported from the anesthesia apparatus 2 to the next work place for blood collection / bleeding work. At this time, the animal's legs are hooked and transported. However, if the animal's back faces the operator, the animal's body is difficult to hook the legs. Therefore, when the animal carried out from the inner gondola 10 faces the back side, the posture of the animal is reversed on the carry-out stand 36 so that the animal's feet are directed toward the worker side. The reversing member is preferably made of a material such as rubber, urethane, or the like, which has high friction and does not damage animals. The position and shape of the reversing member may be appropriately set in consideration of the position to be reversed, the shape of the carry-out table, and the like.

  Moreover, the anesthesia apparatus 2 which concerns on this invention may have the auxiliary | assistant channel | path 38, as FIG. 3 or FIG. 4 showed. The auxiliary passage 38 refers to a passage or a member that closes the gap from the end of the entrance 30 to the opening of the gondola 6 when an animal is carried into the gondola 6. Since the anesthetic tank 4 according to the present invention is cylindrical, there is a gap between the opening of the gondola 6 and the edge of the anesthetic tank 4. Therefore, a passage or member for closing the gap is required. The auxiliary passage 38 may be provided by extending the passage from the end of the carry-in entrance 30, but the anesthesia apparatus 2 according to the present invention rotates the support column 24 and the gondola 6, so If the member is protruded, the gondola 6 and the elevator 12 may come into contact with each other. Therefore, the auxiliary passage 38 according to the present invention is preferably provided with the auxiliary passage 38 on the opening side of the gondola 6, connected to the support column 24, and fixed and held at the same height position as the carry-in entrance 30. As a result, the auxiliary passage 38 can also rotate together with the gondola 6 and the column 24.

  Moreover, the anesthesia apparatus 2 which concerns on this invention may have the shielding member 40 which plugs up the gondola opening part. The shielding member 40 is a member for closing the opening so that the animal does not jump out of the gondola 6 during anesthesia especially when the gondola is moved. As shown in FIG. 3 or FIG. 4, the shielding member 40 may be provided with a plate member in parallel with the elevating orbit of the gondola from the bottom of the auxiliary passage 38 toward the bottom of the anesthetic tank 4. In the present invention, as the shielding member 40, a plate member having a length equal to or longer than the raising / lowering range of the gondola 6 is used. However, a plurality of poles may be provided. What is necessary is just to set suitably about the form of the shielding member 40, and a structure, if the opening part can be block | closed. Further, the shielding member 40 may be provided on the gondola 6.

  Moreover, the anesthesia apparatus 2 which concerns on this invention may provide the casing 28 which coat | covers the opening part and movement apparatus of the anesthesia tank 4, as FIG.1, FIG.3 or FIG.4 showed. When the casing 28 is not provided, the gas filled in the anesthetic tank 4 is affected by the wind, and the gas concentration in the anesthetic tank 4 changes. Therefore, a casing 28 that covers the anesthesia tank 4 is provided to keep the gas concentration in the anesthesia tank 4 stable. Moreover, the fall of the operator or others to the anesthesia tank 4 can be prevented. In the present invention, as shown in FIG. 1, a stainless steel cylindrical body is assembled along the edge of the anesthetic tank 4 to form the casing 28. However, other materials and shapes may be used.

  Moreover, although the anesthesia apparatus 2 which concerns on this invention is not shown in figure, various control apparatuses are provided. This control device refers to a device that controls all the appliances and devices related to the anesthetic device 2 of the present invention, such as the elevator 12, the rotating machine 26, and a control device that controls the amount of carbon dioxide in the anesthetic tank 4. This control device may be provided for each of the various appliances and apparatuses related to the elevator 12, the rotating machine 26, and the anesthesia apparatus 2, or all the apparatus instruments and apparatuses related to the anesthesia apparatus 2 may be integrated.

  Next, the operation of the anesthesia apparatus 2 according to the present invention will be described. 5-8 is explanatory drawing which showed the operation | movement condition of the anesthesia apparatus 2 which concerns on this invention. In the figure, for convenience of explanation, the number of gondola 6 is three, and devices and means other than the anesthetic tank 4 and the gondola 6 are omitted. In addition, in order to identify the three gondola 6, the gondola A, the gondola B, and the gondola C are respectively designated. In addition, animals are stored in advance in the gondola B and the gondola C, and it will be described as one cycle from when an animal is carried into the gondola A until it is carried out at the carry-out port 34 and returned to the carry-in port 30.

(Step 1)
First, an animal is guided to gondola A. At this time, the auxiliary bottom portion 42 blocks the bottom portion of the inner gondola 10. After the animal has moved into the gondola A, if the auxiliary bottom 42 is swung to make the inner gondola 10 into a bottomed state, the animal is in a state of dropping out, the trunk is locked to the holding side surface of the inner gondola 10, and Become. After the auxiliary bottom 42 has moved completely, the gondola A can be lowered. The gondola A is lowered to a predetermined height position and stopped. At this time, the gondola B and the gondola C are stopped at the illustrated positions.
The reason for stopping the gondola 6 at a predetermined height position in the anesthesia tank 4 is that the anesthesia treatment according to the present invention performs preliminary anesthesia before the main anesthesia. In order to prevent oxygen deficiency and difficulty in breathing caused by sudden ingestion of high-concentration gas, preliminary anesthesia is to inhale animals with low concentration and gradually increase the gas concentration to ensure that the animal is safe and secure. It is intended to be anesthetized. And in order to perform preliminary anesthesia using the anesthesia apparatus 2 according to the present invention, the animal is kept waiting at a relatively low gas concentration in the anesthesia tank 4 and then moved to the bottom of the anesthesia tank 4 where the gas concentration is high. You can do it. FIG. 9 is an explanatory diagram showing the depth and gas concentration of the anesthesia tank. The x-axis in the figure indicates the gas concentration, and the y-axis indicates the depth of the anesthetic tank. The black area in the figure is the effective range of anesthesia. Therefore, if the gondola 6 is stopped at a height suitable for preliminary anesthesia within the effective range shown in FIG. 9, the animal can be pre-anesthetized.
(Step 2)
Next, the rotating machine 26 is rotated to stop the gondola B under the carry-out port 34. In the drawing, since there are three gondolas 6, the angle for rotating the rotating machine 26 is 120 °, but the angle for rotating the rotating machine 26 differs depending on the number of gondola 6.
(Step 3)
After the rotation of the rotating machine 26 stops, the gondola B is raised and the gondola C is lowered.
(Step 4)
The gondola B is raised, and the animal is carried out of the gondola 6 at the carry-out port 34. The gondola 6 according to the present invention has a structure in which an inner gondola 10 loaded and held on an outer gondola 8 rotates, and an animal can be carried out by the inner gondola 10 rotating as shown in the figure. . After the animal is carried out from the gondola 6, when the gondola B descends, the inner gondola 10 returns to its original position. The gondola A and the gondola C are stopped at the illustrated height position.
(Step 5)
Next, the gondola B descends and stops at the carry-in port 30. At this time, the auxiliary bottom part 42 swings and stops at a position where the bottom part of the inner gondola 10 is closed. Then, after the animal is guided to the gondola B and the animal has moved into the gondola B, the auxiliary bottom 42 is swung to make the inner gondola 10 into a bottom shape. After the auxiliary bottom part 42 has moved completely, the gondola B can be lowered to a predetermined height position and stopped. At this time, the gondola A and the gondola C are stopped at the illustrated positions. In addition, as a movement opportunity which the auxiliary | assistant bottom part 42 in waiting moves to the position which blocks the bottom missing part of the inner gondola 10, after carrying out an animal from the inside of the gondola 6, it may be when moving to the entrance 30 (Step 3). The gondola 6 may move to the carry-out port 34 and move after passing through the waiting auxiliary bottom 42 and may be set as appropriate.
(Step 6)
Next, the rotating machine 26 is rotated to stop the gondola C under the carry-out port 34.
(Step 7)
After the rotation of the rotating machine 26 stops, the gondola C is raised and the gondola A is lowered.
(Step 8)
Next, the gondola C is raised and the animal is carried out of the gondola 6 at the carry-out port 34. After carrying out the animal from the gondola 6, the gondola C descends. The gondola A and the gondola B are stopped at the illustrated height position.
(Step 9)
Next, the gondola C descends and stops at the entrance 30. At this time, the auxiliary bottom part 42 swings and stops at a position where the bottom part of the inner gondola 10 is closed. Thereafter, the animal is guided to the gondola C, and after the animal is stored in the gondola C, the auxiliary bottom 42 is swung to make the inner gondola 10 into a bottom shape. After the auxiliary bottom part 42 has moved completely, the gondola C can be lowered to a predetermined height position and stopped. At this time, the gondola A and the gondola B are stopped at the illustrated positions.
(Step 10)
Next, the rotating machine 26 is rotated to stop the gondola A under the carry-out port 34.
(Step 11)
After the rotation of the rotating machine 26 stops, the gondola A is raised and the gondola B is lowered.
(Step12)
