Description

Anal incision and sacral cutting device of the carcass

[0001] The present invention relates to a device for anal incision and sacral cutting of a tube, and more specifically, to a device for anal incision and sacral cutting of a tube configured to automatically incise the anus of a tube and cut the sacrum.

[0002] One of the main processes in a slaughterhouse is the removal of the anus from the carcass (slaughtered animal).

[0003] The anal removal operation of such a carcass is usually performed by two workers using a manual anal removal device.

[0004] However, when workers directly remove the carcass's anus, there is a problem in that the results vary depending on the worker's skill level. For example, if an inexperienced worker causes the internal organs to rupture while removing the anus, foreign matter inside the organs may leak out and spread into the meat. If such foreign matter spreads into the meat, the marketability of the carcass is significantly reduced.

[0005] In addition, since workers must incise the anal area using a manual anal excision instrument for every operation, they may suffer musculoskeletal disorders and may be seriously injured during the process of incising the anal area using the instrument.

[0006] In addition, the sacrum of the carcass must be cut as a preliminary step for the abdominal incision and splitting of the carcass, and if this process is also performed manually, there are difficulties in the work.

[0007] Therefore, various research and development are needed for automated devices designed to automatically cut the anus of a carcass and sever the sacrum, rather than manually.

[0008] The technical objective of the present invention to solve the above-mentioned problems is to provide a device for anal incision and sacral cutting of a carcass configured to automatically incise the carcass's anus and cut the sacrum.

[0009] To achieve the above technical objective, one embodiment of the present invention provides an anal incision and sacral cutting device for a carcass, comprising: an anal incision tool having a guide rod inserted into the anus of a carcass and an anal incision blade having a hollow hole formed inside and cutting the carcass surrounding the anus; a sacral cutting tool provided on the upper part of the anal incision tool and moving in the forward and backward directions from the anal incision tool to cut the sacral bone of the carcass; and a sacral avoidance tool provided on the lower part of the anal incision tool to prevent the tailbone of the carcass from covering the anus; wherein the anal incision tool, the sacral cutting tool, and the sacral avoidance tool are provided in the form of a single tool module.

[0010] In one embodiment of the present invention, the anal incision tool comprises: a body casing having a driving unit provided in a receiving space formed therein; an anal incision blade having a cylindrical shape to form the hollow hole, which rotates by power provided from the driving unit and cuts out the carcass surrounding the anus in a circular manner; a guide rod inserted through the hollow hole and inserted into the anus of the carcass to prevent the internal organs from bursting due to the anal incision blade during the process of the anal incision blade cutting the carcass surrounding the anus; and a power transmission shaft connecting the driving unit and the anal incision blade and transmitting rotational force provided from the driving unit to the anal incision blade; wherein the front end of the guide rod may be positioned ahead of the front end of the anal incision blade.

[0011] In one embodiment of the present invention, the guide rod comprises: an insertion part that is inserted into the anus of a conductor and maintains an internal organ connected to the rectum parallel to the direction of entry of the anal incision blade; a connecting bar disposed within the hollow hole and having one end connected to the insertion part; and a fastening part coupled to the other end of the connecting bar and coupled to the power transmission shaft; wherein a plurality of air passage holes may be formed along the circumference of the fastening part.

[0012] In one embodiment of the present invention, the apparatus further comprises: a connecting casing coupled to the body casing and protecting the power transmission shaft disposed inside from the outside; and an air control valve coupled to the connecting casing and supplying air into the connecting casing or sucking in air inside the connecting casing and discharging it to the outside; wherein when air is supplied into the connecting casing through the air control valve, the air supplied into the connecting casing is supplied to a first air passage hole formed inside the power transmission shaft through an opening hole formed in the power transmission shaft, the air supplied to the first air passage hole is supplied to a second air passage hole formed inside the fastening part communicating with the first air passage hole, and the air supplied to the second air passage hole can be discharged to the hollow hole through the air movement hole formed in the fastening part.

[0013] In one embodiment of the present invention, during the process in which the anal cutting blade cuts the anus of the conductor in a circular manner, the air control valve is configured to suck air into the connecting casing, and when the anal cutting blade has completed the anal cutting of the conductor, the air control valve is configured to supply air into the connecting casing.

[0014] In one embodiment of the present invention, the tailbone avoidance tool may include: a lower casing coupled to the lower part of the body casing; a first cylinder part provided within the lower casing; a pair of rod parts spaced apart at a predetermined interval and extending or retracting by the operation of the first cylinder part; and a tailbone fixing part, each having its end portion coupled to the end portion of the spaced-apart rod part to prevent the tailbone of the conductor from covering the anus.

[0015] In one embodiment of the present invention, the sacral cutting tool comprises: an upper casing provided on the upper part of the body casing and having a moving guide provided on the lower part; a power unit provided within the upper casing; a rotational force transmission unit having one end coupled to the power unit and the other end having a first gear; a rotary saw blade unit having a second gear meshing with the first gear and cutting the sacral bone of a conductor; a protective cover protecting the rotational force transmission unit from the outside and supporting the rotary saw blade unit; and a second cylinder unit controlling the forward and backward movement of the upper casing from the body casing; wherein, when the second cylinder unit is operated, the moving guide can move along the longitudinal direction of a moving rail provided on the upper part of the body casing.

[0016] The effects of the anal incision and sacral bone cutting device of a conductor according to the present invention described above are as follows.

[0017] According to the present invention, based on scan data of a carcass scanned by a scanning unit, a guide rod provided in an anal incision tool is inserted into the anus of the carcass, and the anal incision blade rotates to cut out the carcass surrounding the anus into the required circular shape. Since this anal incision operation is performed automatically through the anal incision tool, the operation can be carried out simply and accurately.

[0018] Here, the anal incision tool is operated in a state where the tailbone of the carcass is prevented from covering the anus by the tailbone avoidance tool, thereby preventing operational defects or malfunctions caused by the tailbone during the anal incision process.

[0019] According to the present invention, the sacral cutting tool is configured to automatically cut the sacrum of a carrier while it is moved to a required position of the carrier by an automatic robot. Accordingly, the sacrum cutting operation of the carrier can be performed easily.

[0020] As such, the anal incision and sacral cutting device of a conductor according to the present invention can easily perform various operations on the conductor as the anal incision tool, the sacral cutting tool, and the coccyx avoidance tool are provided in the form of a single tool module.

[0021] The effects of the present invention are not limited to the effects described above, and should be understood to include all effects that can be inferred from the configuration of the invention described in the detailed description of the invention or the claims.

[0038] As shown in FIGS. 1 to 11, the anal incision and sacral cutting device (1000) of a carcass is configured to automatically cut the anal incision and sacral bone of a carcass (P). The anal incision and sacral cutting device (1000) of a carcass equipped with such an anal incision tool (100), a sacral cutting tool (200), and a tailbone avoidance tool (300) is described as a tool module, which is a brief term, and the content of the invention is to be explained. Subsequently, the anal incision and sacral cutting device (1000) of a carcass is described as a tool module.

[0039] In the present invention, the example is that the carcass (P) hanging on the hanger (10) is a pig. Here, the carcass (P) that is worked on through the tool module (1000) is not necessarily limited to a pig, and may be various carcasses (P) other than a pig, such as a cow.

[0040] In this way, the conductor (P) moves along the length direction of the main conveyor (20) with the ankle portion of the hind leg of the conductor (P) hanging on the hanger (10).

[0041] Meanwhile, the scanning unit (30) is configured to scan a conductor (P) that is moved by the main conveyor (20).

[0042] Scan data scanned through this scanning unit (30) is transmitted to an automatic robot (40) to which a tool module unit (1000) to be described later is combined, and based on the scan data provided from the scanning unit (30), the automatic robot (40) can perform anal incision and sacral bone cutting operations of the conductor (P) while moving the tool module unit (1000) to a required position.

[0043] Here, the scan data obtained through the scanning unit (30) can also generate a 3D image of the conductor (P) through an image conversion operation.

[0044] This scanning unit (30) may be composed of, for example, a 2D Lidar. Alternatively, the scanning unit (30) may be composed of a 3D scanner, and any device that can acquire more accurate scan data of the conductor (P) may be used.

[0045] Meanwhile, the tool module (1000) moves to the required position by the automatic robot (40) and performs an anal incision and sacral bone cutting operations on the conductor (P).

[0046] Such a tool module (1000) may include an anal incision tool (100), a sacral cutting tool (200), and a coccyx avoidance tool (300).

[0047] Here, based on the anal incision tool (100), the sacral cutting tool (200) is provided on the upper part of the anal incision tool (100), and the tailbone avoidance tool (300) is provided on the lower part of the anal incision tool (100).

[0048] In this way, the tool module part (1000) is formed such that the anal incision tool (100), the sacral cutting tool (200), and the coccyx avoidance tool (300) are formed as a single tool module, so that the anal incision and sacral cutting operations of the carcass (P) can be performed continuously and accurately.

[0049] Here, the anal incision tool (100) may include a body casing (110), an anal incision blade (120), a guide rod (130), a power transmission shaft (140), a connecting casing (150), and an air control valve (160).

[0050] A receiving space (not shown) is formed inside the body casing (110). A driving unit (170) may be provided in this receiving space. Rotational power generated from such a driving unit (170) is provided to an anal incision blade (120) and a guide rod (130), so that the anal incision blade (120) and the guide rod (130) can be rotated.

[0051] For example, such a drive unit (170) may be equipped with an air wing (not shown) inside. When air is introduced from the outside into the interior of such a drive unit (170), the air wing rotates and may provide rotational power to the power transmission shaft (140) connected to the drive unit (170). Alternatively, the drive unit (170) may be made of a general motor, and the drive unit (170) for rotating the power transmission shaft (140) may be made in various forms.

[0052] And the connecting casing (150) is connected to the front side, which is the front part of the body casing (110). This connecting casing (150) is configured to protect the power transmission shaft (140) placed inside from the outside.

[0053] And the air control valve (160) is coupled to the connecting casing (150) and is configured to supply air into the connecting casing (150) or to draw in air from the connecting casing (150) and discharge it to the outside. The operation of such an air control valve (160) will be explained in detail later.

[0054] And the anal cutting blade (120) is coupled to a power transmission shaft (140) coupled to a driving unit (170), and through the rotational force transmitted from the power transmission shaft (140), the carcass around the anus of the carcass (P) is cut out in a circular shape.

[0055] This anal incision blade (120) is formed in a cylindrical shape with a hollow hole (121) formed inside, and the blade portion provided at the front end of the anal incision blade (120) cuts out the flesh around the anus in a circular shape through rotation.

[0056] And the guide rod (130) is inserted into the anus of the carcass (P) during the process of anal incision of the carcass (P) to prevent the internal organs connected to the anus from bursting while the anal incision blade (120) cuts the carcass meat around the anus. This guide rod (130) is configured to be directly inserted into the anus of the carcass (P) to guide the incision location of the anal incision blade (120) so that the anal incision blade (120) accurately cuts the required carcass meat around the anus. Here, the front end of the guide rod (130) is positioned ahead of the front end of the anal incision blade (120) to prevent the internal organs connected to the anus from bursting due to the anal incision blade (120).

[0057] These guide rods (130) may include an insertion part (131), a connecting bar (132), and a fastening part (133).

[0058] Here, the insertion part (131) is positioned at the front end of the guide rod (130) and is configured to be inserted into the anus of the carcass (P). This insertion part (131) is formed with an overall rounded shape so that it is inserted smoothly without any obstruction occurring during the process of inserting it into the rectum through the anus. This insertion part (131) is configured to keep the internal organs connected to the rectum parallel to the direction of entry of the anal incision blade (120) during the process of the anal incision blade (120) cutting the carcass around the anus, thereby preventing the internal organs connected to the rectum from bursting due to the anal incision blade (120).

[0059] And the connecting bar (132) is placed within the hollow hole (121) formed in the anal incision blade (120). One end of the connecting bar (132) is connected to the insertion part (131), and the other end is connected to the fastening part (133), so that the insertion part (131) can be supported by the connecting bar (132).

[0060] And the connecting part (133) is coupled with the power transmission shaft (140). In such a connecting part (133), a plurality of air passage holes (134) are spaced apart along the circumference of the connecting part (133). These air passage holes (134) are configured to communicate with a second air passage hole (135) formed inside the connecting part (133). Accordingly, for example, when air is supplied into the connecting casing (150) through the operation of the air control valve (160), the air supplied to the second air passage hole (135) can be discharged into the hollow hole (121) through the air passage hole (134). Conversely, when air is sucked into the connecting casing (150) through the operation of the air control valve (160), the air in the hollow hole (121) can be moved to the second air passage hole (135) through the air passage hole (134).

[0061] This air control valve (160) is configured to suck air into the connecting casing (150) during the process in which the anal cutting blade (120) cuts the anus of the carcass (P). This is to prevent the anal cutting blade (120) from rotating smoothly because the carcass around the anus detaches during the process in which the anal cutting blade (120) cuts the anus of the carcass (P) and jams occur on the blade portion of the anal cutting blade (120). That is, small pieces of carcass detached from the carcass during the process in which the anal cutting blade (120) cuts the anus of the carcass (P) can be moved toward the connecting part (133) by the air suction force provided into the interior of the hollow hole (121) through the air transfer hole (134). Therefore, during the process of the anal incision blade (120) cutting the carcass around the anus, the carcass detached from the carcass can be prevented from getting stuck in the blade portion of the anal incision blade (120).

[0062] And the air control valve (160) is configured to supply air into the interior of the connecting casing (150) after, for example, the anal incision of the conductor (P) is completed through the anal incision blade (120). This is to make it easier to separate the anal portion of the circularly incised conductor (P) from the anal incision blade (120) as the air supplied through the second air flow hole (135) is discharged into the hollow hole (121) through the air transfer hole (134).

[0063] Meanwhile, the power transmission shaft (140) is configured to connect the driving unit (170) and the anal incision blade (120). The rotational power transmitted from the driving unit (170) through the power transmission shaft (140) is provided to the anal incision blade (120), so that the anal incision blade (120) can cut the flesh around the anus.

[0064] An opening hole (141) is formed in the power transmission shaft (140). This opening hole (141) is configured to communicate with a first air flow hole (142) formed inside the power transmission shaft (140). Accordingly, when air is supplied into the connecting casing (150) through the air control valve (160), the air supplied into the connecting casing (150) can move to the first air flow hole (142) through the opening hole (141).

[0065] In this way, the air supplied to the first air flow hole (142) is moved to the second air flow hole (135) formed inside the connecting part (133) which is in communication with the first air flow hole (142), and the air moved to the second air flow hole (135) can be moved to the hollow hole (121) through the air moving hole (134) formed in the connecting part (133).

[0066] Conversely, when air is sucked in and discharged from the connection casing (150) through the air control valve (160), the air in the hollow hole (121) can be discharged via the air transfer hole (134), the second air flow hole (135), the first air flow hole (142), and the opening hole (141).

[0067] Meanwhile, the tailbone avoidance tool (300) is configured to prevent the tailbone of the carcass (P) from covering the anus during the process in which the anal incision tool (100) incisions the anus of the carcass (P), thereby preventing operational failure or malfunction of the anal incision tool (100) caused by the tailbone.

[0068] This tailbone avoidance tool (300) may include a lower casing (310), a first cylinder part (320), a rod part (330), and a tailbone fixing part (340).

[0069] Here, the lower casing (310) is connected to the lower part of the body casing (110). A first cylinder part (320) is provided within this lower casing (310) to move the tailbone fixing part (340) to a required position. Here, the tailbone fixing part (340) prevents the tailbone of the body (P) from covering the anus.

[0070] Both ends of such a tailbone fixation part (340) are each connected to a pair of rod parts (330) spaced apart at a predetermined interval. Here, the rod parts (330) are extended and retracted by the operation of the first cylinder part (320), thereby moving the tailbone fixation part (340) to a required position.

[0071] This tailbone fixation part (340) is formed in a U-shape, for example, and prevents the tailbone of the body (P) from bending and covering the anus of the body (P).

[0072] Meanwhile, a sacral cutting tool (200) is provided on the upper part of the anal incision tool (100). This sacral cutting tool (200) is moved forward and backward from the anal incision tool (100) and is configured to cut the sacral bone of the carcass (P).

[0073] Such a sacral cutting tool (200) may include an upper casing (210), a power unit (220), a rotational force transmission unit (230), a rotating saw blade unit (240), a protective cover (250), and a second cylinder unit (260).

[0074] Here, the upper casing (210) is provided on the upper part of the body casing (110). A moving guide (211) is provided on the lower part of the upper casing (210) and coupled to a moving rail (111) provided on the upper part of the body casing (110). Accordingly, the upper casing (210) can be moved forward and backward from the body casing (110) by the operation of the second cylinder part (260). That is, the upper casing (210) can be moved forward and backward along the longitudinal direction of the moving rail (111).

[0075] A power unit (220) is provided within the upper casing (210) as described above. This power unit (220) provides rotational power to a rotating saw blade (240) that cuts the sacrum of the conductor (P).

[0076] Here, the rotational power of the power unit (220) can be supplied to the rotating saw blade unit (240) through the rotational power transmission unit (230). One end of the rotational power transmission unit (230) is connected to the power unit (220), and the other end of the rotational power transmission unit (230) is connected to the rotating saw blade unit (240). Specifically, the first gear (231) provided at the other end of the rotational power transmission unit (230) meshes with the second gear (241) provided at the rotating saw blade unit (240), so that the rotational power of the power unit (220) can be supplied to the rotating saw blade unit (240). Here, the gear coupling structure of the first gear (231) and the second gear (241) can be formed, for example, in the form of a bevel gear.

[0077] And the protective covers (250) form a pair and are configured to support the rotating saw blade section (240) on both sides. Here, a rotational power transmission section (230) is disposed in one of the two protective covers (250) to transmit rotational power generated from the power section (220) to the rotating saw blade section (240). These protective covers (250) protect the rotational power transmission section (230) from the outside.

[0078] And the second cylinder part (260) moves the rotating saw blade part (240) to the required position while the rotating saw blade part (240) rotates, and cuts the sacrum of the body (P).

[0079] In this way, the tool module part (1000) is equipped with an anal incision tool (100), a sacral cutting tool (200), and a coccyx avoidance tool (300) in the form of a single tool module, so that the anal incision and sacral cutting operations of the carcass can be easily performed.

[0080] However, this is merely a preferred embodiment of the present invention, and the scope of the rights of the present invention is not limited by the scope of description of such embodiment.

[0081] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical spirit or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.
