More specifically, the present invention relates to an abdominal fat peeling device that enables abdominal fat to be easily and safely peeled or stripped from carcasses of livestock meat, particularly pork carcasses. [Background technology]

[0002] Traditionally, the butchering of livestock such as cows and pigs involves bleeding, skinning, and then removing the internal organs, head, and limbs. The animal is then cut in half along the spine at the center to produce a half-cut block (carcass), and the abdominal fat (the fatty part on the inside of the carcass) is then removed as a preparatory step for the deboning process.

[0003] Such removal of abdominal fat is accomplished by grasping the ends of the abdominal fat with the hands and pulling or peeling it away. However, the task of removing abdominal fat requires a strong force and is hard work, as there is a risk of the fat in the abdominal fat causing the hands to slip.

[0004] Thus, an example of a device that enables abdominal fat to be easily removed from carcasses is disclosed in Patent Document 1.

[0005] Japanese Patent Application Publication No. 2005-006634 (Patent Document 1) proposes an abdominal fat removal device that makes it easy to remove abdominal fat adhering to the ribs of a carcass after the back splitting process performed in the meat processing step.

(b) Attach a wire fixing bracket (4) to the top of the air cylinder (2) and attach a pulley (5) to the bottom. (c) The suspension wire (6) attached to the wire fixing bracket (4) is passed through the wire guide roller (1) and the pulley (5), and a suspension bracket (7) is attached to the end of the wire. (d) Attach air cylinders (10) and (11) with upper and lower clamping plates (8) and (9) to both ends of the hanging bracket (7). (e) A foot switch (12) for operating the air cylinder (10), a foot switch (13) for operating the air cylinder (11), and a foot switch (14) for operating the air cylinder (2) are installed at the feet. It is structured as follows. [Prior art documents] [Patent documents]

The present invention is characterized by the following: Effect of the Invention

[0016] The abdominal fat scraping device of this invention is used to peel or strip abdominal fat adhering to the carcass of livestock meat, particularly pork carcass, and comprises a device main body, a clamping means for clamping the abdominal fat, and a lifting means for raising and lowering the clamping means, the clamping means having a pair of clamping pieces consisting of an upper clamping piece and a lower clamping piece, the upper clamping piece having an upper claw portion consisting of a rib-like protrusion of a required height rising from the edge on the tip side, and the lower clamping piece having a lower claw portion consisting of a rib-like protrusion of a required height rising from the edge on the tip side, the upper clamping piece and the lower clamping piece being arranged so that their respective claw portions face each other, and are configured so that the claw portions abut or move away from each other. Therefore, with this abdominal fat scraping device, abdominal fat can be easily scraped or peeled off in an upward or downward direction by raising or lowering the clamping means. Therefore, this abdominal fat scraping device makes it possible to easily and safely scrape or remove abdominal fat. In this case, in the abdominal fat scraping device, in order to abut or separate the claw portions from each other, for example, the upper clamping piece and the lower clamping piece can be configured so that their respective base ends are connected by a support shaft and at least one of the clamping pieces is capable of rotating in the vertical direction around the support shaft. In addition, in this invention, the abdominal fat peeling device further includes a control means for controlling the lifting means and the clamping means, and the clamping means is configured so that one left-right end of the clamping means can swing or rotate freely up and down, and when peeling or stripping abdominal fat, the left-right end of the clamping means swings or rotates up and down simultaneously with the raising or lowering of the clamping means.

[0017] In the abdominal fat scraping device, the upper clamping piece and the lower clamping piece can both be configured so that their front edges bulge outward in an arc shape. With this configuration, it is possible to easily grab (hold or grasp) the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached.

[0018] In the abdominal fat scraping device, the clamping means can be disposed with one end in the left-right direction inclined downward at a predetermined angle with respect to the horizontal line. With this configuration, the clamping means is able to firmly grasp (hold or grip) the abdominal fat.

[0019] In the abdominal fat scraping device, the clamping means can be constructed so that one end in the left-right direction is capable of swinging or rotating up and down. With this configuration, the abdominal fat can be easily grasped, and the abdominal fat can be easily peeled or stripped off regardless of whether the carcass is the left or right side. Furthermore, when peeling or stripping abdominal fat, a twist can be added by swinging or rotating one end of the clamping means in the up and down direction at the same time as the clamping means is raised or lowered, thereby making it possible to peel or strip the abdominal fat more neatly. In the present invention, the clamping means is constructed so that one end in the left-right direction can swing or rotate up and down.

[0020] In the abdominal fat scraping device, each of the claw portions can be configured to increase in diameter from the base end toward the tip end, thereby inclining outward at a predetermined angle. With this configuration, slippage is more reliably prevented when the abdominal fat is clamped, making it possible to firmly grasp the abdominal fat.

[0021] Furthermore, in the abdominal fat scraping device, the claw portions can be configured so that their thickness gradually increases from the center toward each end. With this configuration, it is possible to easily grab (hold) the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached.

[0022] Furthermore, in the abdominal fat scraping device, the rear end side of the upper surface (the surface on which the claw portion is formed) of the clamping piece main body constituting the lower clamping piece can be configured to be inclined downward. With this configuration, fat and grease particles from abdominal fat adhering to the claw portion, etc., flow rearward along the inclined surface formed on the upper surface and are discharged to the outside, making it possible to suppress or with an extremely high probability prevent the accumulation of abdominal fat in the clamping means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, an embodiment of the abdominal fat scraping device according to the present invention will be specifically described with reference to the accompanying drawings. It should be noted that the present invention is not limited to the disclosed embodiments, and various improvements can be made without departing from the spirit and scope of the present invention.

[0025] In this invention, the abdominal fat removing device 1 is used to remove or strip abdominal fat from the carcass of a livestock carcass for meat, and as can be seen in Figure 1, is composed of a device main body 2, a clamping means 3 for clamping (or gripping) the abdominal fat, and a lifting means 4 for raising and lowering the clamping means 3.

[0026] In Figs. 1 and 2, the device main body 2 is configured as a vertically long cylindrical body having a required size, and the device main body 2 itself is also configured to be movable in the vertical direction. In this embodiment, the device main body 2 is provided with a fixed chuck (not shown) on its upper part, so that the device can be prevented from moving due to recoil when the abdominal fat removal device 1 is started (driven).

[0027] The device main body 2 can be disposed, for example, by attaching its upper end to a ceiling. In this embodiment, a rail (not shown) extending in the left-right direction is laid on the ceiling, and the device main body 2 is attached to a moving body (not shown) that moves on this rail. Therefore, since the device main body 2 is configured to be movable in the left-right direction, it is possible to efficiently peel or strip the abdominal fat from a plurality of lined up carcasses.

[0028] The moving body includes a cylindrical shaft member extending in the left-right direction, and an upper end of the device main body 2 is supported by the shaft member so as to be swingable in the front-rear direction. Therefore, the device body 2 is capable of swinging in the front-rear direction around the axis of the shaft member.

[0029] The abdominal fat scraping device 1 is provided with a lifting means 4 for lifting the clamping means 3 as shown in Figs. There are no particular limitations on the location of the lifting means 4, so long as it does not make it difficult to peel or strip the abdominal fat, and the lifting means 4 can be appropriately disposed at a predetermined position on the device main body 2.

[0030] The lifting means 4, as shown in FIG. 2, enables the clamping means 3 to move (lift) up and down along the longitudinal direction (height direction) of the device main body 2. The clamping means 3, which is configured so as to be able to rise and fall by the lifting means 4, can easily peel or tear off the abdominal fat by rising or lowering while clamping the abdominal fat. For example, when the clamping means 3 is in a state of clamping the vicinity of the lower end of the abdominal fat, the abdominal fat can be peeled or stripped upward (particularly, peeled up) by raising the clamping means 3. As a result, the burden on the worker in peeling or stripping off the abdominal fat is reduced. Therefore, there is no particular limitation on the lifting means 4 as long as the clamping means 3 is configured to be able to rise and fall, and a known lifting means such as an air cylinder can be selected.

[0031] In this embodiment, an air cylinder is selected as the lifting means 4. That is, the lifting means 4 is configured to be driven by air, but a known driving method other than air driving can be selected.

[0032] As shown in Figure 3, the clamping means 3 is composed of a clamping means main body 31 that is freely movable up and down along the height direction of the device main body 2 by the lifting means 4, and a pair of clamping pieces 32 that clamp (or grip) the abdominal fat.

[0033] 1 and 2, the clamping means 3 is attached to the lifting means 4, in this embodiment, to the front side of the lifting means 4, via a mounting member 7 formed in a rectangular parallelepiped shape. Therefore, the clamping means 3 rises and falls in conjunction with the rise and fall of the mounting member 7, so that by raising and lowering the clamping means 3 while clamping the abdominal fat, it is possible to peel or strip the abdominal fat upward or downward.

[0034] As shown in FIG. 3, the pair of clamping pieces 32 is composed of an upper clamping piece 321 and a lower clamping piece 322. In this embodiment, the shapes of the clamping piece main body 321a constituting the upper clamping piece 321 and the clamping piece main body 322a constituting the lower clamping piece 322 are both approximately semi-elliptical or semi-circular in plan view, but as described below, shapes other than these may be selected as long as the claw portion 321c of the upper clamping piece 321 and the claw portion 322c of the lower clamping piece 322 are configured to be able to abut against each other. Preferably, the clamping piece main body 321a and the clamping piece main body 322a are both formed so that the front edge portion bulges outward in an arc shape. With this configuration, it is possible to easily grab (hold) the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached.

[0035] In Figure 3, the upper clamping piece 321 and the lower clamping piece 322 are connected at the base end by a cylindrical support shaft 323, and at least one of the upper clamping piece 321 and the lower clamping piece 322 is configured to be rotatable (swingable), so that the clamping means 3 is configured to be able to come into contact with and separate from each other at the tip end (free end).

[0036] In this embodiment, the clamping means 3 has the lower clamping piece 322 fixed to the lower end of the clamping means body 31, and the upper clamping piece 321 supported so as to be freely swingable on a support shaft 323 journalled on the bearing portion 322b of the clamping means body 31. The upper clamping piece 321 is connected to a protrusion 321d protruding from its upper portion and is configured to swing in conjunction with the movement in the forward and backward directions of a rod main body 33 of a required length which is arranged so as to be movable in the forward and backward directions. More specifically, the protrusion 321d has a through hole formed at its tip in a direction (left-right direction) perpendicular to the direction in which the rod main body 33 moves, and the rod main body 33 is rotatably attached to a cylindrical rod-shaped shaft member 324 whose tip is inserted into this through hole, while the base end is connected to a power member 34 that enables the rod main body 33 to move in the forward and backward directions. Therefore, the upper clamping piece 321 swings, that is, opens and closes, in accordance with the movement of the rod main body 33 in the front-rear direction.

[0037] In this embodiment, the upper clamping piece 321 and the lower clamping piece 322 are configured so that when spaced apart from each other, the angle (opening angle) between their respective contact surfaces is approximately 17°; however, the size of the separation can be selected according to the size of the abdominal fat, etc., and there is no particular limitation on it.

[0038] As shown in FIGS. 4 and 5, the upper clamping piece 321 is configured with a clamping piece main body 321a made of a plate-like body having a required thickness and a substantially semi-elliptical or semi-circular shape in plan view. As described above, the shape of the plate-like body constituting the clamping piece main body 321a may be a shape other than approximately semi-elliptical or semi-circular when viewed in a plane, but preferably, the front edge portion is formed so as to bulge in an arc shape toward the outside. This configuration makes it possible to easily grasp the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached.

[0039] The clamping piece main body 321a has a pair of bearing portions 321b, 321b on one end (rear end) side which are protruded downward at a required angle so as to be roughly V-shaped when viewed from the side, and which are supported rotatably around a support shaft 323 provided on the clamping means main body 31, and has a claw portion (upper claw portion) 321c on the other end side which consists of a rib-shaped protrusion that abuts or separates from the claw portion 322c of the lower clamping piece 322.

[0040] The claw portion (upper claw portion) 321c has a roughly horseshoe shape (U-shape) when viewed from above and has the required height, and is formed on the front edge portion (edge ​​portion on the tip side) of the clamping piece main body 321a, protruding downward along the shape of this front edge portion.

[0041] There is no particular limit to the inclination angle of the pair of bearing portions 321b, 321b, but for example, the angle is about 20° to 30° with respect to the upper surface (contact surface) of the upper claw portion 321c of the upper clamping piece 321. In this embodiment, the angle is set to about 25°. The inclination angle of the pair of bearing portions 321b, 321b is usually set to the same angle as the inclination angle of a bearing portion 322b of the lower clamping piece 322, which will be described later.

[0042] As shown in Figures 6 and 7, the lower clamping piece 322 is configured to correspond to the upper clamping piece 321, and is composed of a clamping piece main body 322a consisting of a plate-like body having a roughly semi-elliptical or semi-circular shape in a plan view and a required thickness. As described above, the shape of the plate-like body constituting the clamping piece main body 322a may be a shape other than an approximately semi-elliptical or semi-circular shape when viewed from above, but preferably, the front edge portion is formed so as to bulge in an arc shape toward the outside. With this configuration, it is possible to easily grab (hold) the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached.

[0043] The clamping piece main body 322a has a bearing portion 322b on one end (rear end) side which is protruded upward at a required angle so as to be roughly inverted L-shaped when viewed from the side, and is held by a support shaft 323 provided on the clamping means main body 31, and has a claw portion (lower claw portion) 322c on the other end side which consists of a rib-shaped protrusion that abuts or separates from the claw portion 321c of the upper clamping piece 321.

[0044] The claw portion (lower claw portion) 322c has a roughly horseshoe shape (U-shape) in a planar view with the required height, and is formed to protrude upward along the shape of the front edge portion (edge ​​portion on the tip side) of the clamping piece main body 322a so as to face the claw portion (upper claw portion) 321c.

[0045] There is no particular limit to the inclination angle of the bearing portion 322b, but for example, it is about 20° to 30° with respect to the upper surface (contact surface) of the lower claw portion 322c of the lower clamping piece 322. In this embodiment, the angle is set to about 25°. The inclination angle of the bearing portion 322b is usually set to the same angle as the inclination angle of the pair of bearing portions 321b, 321b.

[0046] In this embodiment, the lower clamping piece 322 is configured so that the rear end side of the upper surface (the surface on which the claw portion 322c is formed) of the clamping piece main body 322a constituting it forms an inclined surface 322d that slopes downward at a predetermined angle toward the outside (rear end side). With this configuration, even if abdominal fat or grease particles adhere to the claw portions 321c, 322c, the adhered fat flows backward along the inclined surface 322d and is discharged to the outside. Therefore, accumulation of abdominal fat and grease in the clamping means 3 is suppressed or prevented with an extremely high probability.

[0047] In a pair of clamping pieces 32 having such a configuration, the upper clamping piece 321 and the lower clamping piece 322 are arranged so that the claw portions 321c, 322c face each other, and at least one of the clamping pieces 321, 322 is configured to be able to swing up and down with the support shaft 323 as a fulcrum so that the claw portions 321c, 322c abut or move away from each other. With this configuration, when the abdominal fat is pinched or gripped, the pair of claw portions 321c, 322c firmly pinch or grip the abdominal fat, so slipping due to the fat in the abdominal fat is suppressed or highly likely prevented.

[0048] 3 to 7, the rib-like protrusions constituting the claw portions 321c, 322c are each formed so as to increase in diameter from the base end side to the tip end side, and are configured to be inclined outward at a predetermined angle α. With regard to the rib-like protrusions constituting the claw portions 321c, 322c, at least one of them can be configured to be inclined outward at a predetermined angle α, but preferably both are configured to be inclined outward at a predetermined angle α. With this configuration, slippage is more reliably prevented when the abdominal fat is clamped, making it possible to firmly grasp the abdominal fat. In Figures 3 to 7, the protrusions are configured so that their tips are inclined outward at an angle of approximately 25° from the vertical direction, but the inclination angle of the protrusions can be set, for example, to be inclined outward at an angle of 10° to 40° from the vertical direction.

[0049] Carcasses of livestock meat products, particularly pork carcasses, are typically hung head-side up with the end of the belly fat (usually the lower end) attached to the carcass at an angle. Therefore, in this invention, it is preferable that the clamping means 3 is attached with either the left or right end inclined downward at a predetermined angle β with respect to the horizontal line, corresponding to the inclination angle of the end of the abdominal fat adhering to the carcass. With this configuration, the holding means 3 can hold or grasp the abdominal fat firmly. In Figures 8 and 9, the clamping means 3 is attached with its right end inclined downward at a predetermined angle β with respect to the horizontal line, corresponding to the inclination angle of the end of the abdominal fat adhering to the carcass.

[0050] The inclination angle β of the clamping means 3 may be appropriately selected so as to be approximately the same as the inclination angle of the end (lower end) of the abdominal fat adhering to the carcass (specifically, its inside), and there is no particular limitation. For example, when peeling or stripping abdominal fat adhering to the carcass on the right side, the right end of the abutment surface formed when the claw portions 321c, 322c of each clamping piece 321, 322 abut against each other can be configured to be inclined downward at an angle of 20° to 60° with respect to the horizontal plane H, as shown in Figure 8, and when peeling or stripping abdominal fat adhering to the carcass on the left side, the left end of the abutment surface formed when the claw portions 321c, 322c of each clamping piece 321, 322 abut against each other can be configured to be inclined downward at an angle of 20° to 60° with respect to the horizontal plane H, as shown in Figure 9. In this embodiment, the right end of the contact surface formed when the claw portions 321c, 322c of the clamping pieces 321, 322 come into contact with each other is configured to be inclined downward at an angle of about 33° with respect to the horizontal plane H.

[0051] Furthermore, the clamping means 3 can be attached so that one end in the left-right direction can swing or rotate up and down. With this configuration, the inclination angle of the clamping means 3 can be appropriately changed according to the angle of the end of the abdominal fat, so that the abdominal fat can be easily grasped and can be easily peeled or stripped off regardless of whether the carcass is on the left or right side. Furthermore, when peeling or stripping abdominal fat, a twist can be added by swinging or rotating one end of the clamping means 3 in the up and down direction at the same time as the clamping means 3 is raised or lowered, so that the abdominal fat can be peeled or stripped more neatly.

[0052] 8 and 9, the clamping means 3 is attached to a mounting member 7 via a mounting plate 8 made of a plate-like body having a substantially L-shape when viewed from the front. The means (swinging or rotating means) 5 for swinging or rotating one end of the clamping means 3 in the left-right direction up and down is composed of a headed, cylindrical swinging or rotating means main body 5a with an open bottom, and a long rod-shaped body 5b that is engaged with the inside of the swinging or rotating means main body 5a so as to be able to move up and down freely and not to be separated. The mounting plate 8 has one end (upper end) equipped with a support shaft 323 on which the upper clamping piece 321 is supported so as to be freely swingable, and the other end (lower end) is connected to the lower end of the rod-shaped body 5b of the swinging or rotating means 5 and to a support shaft 5c so as to be swingable up and down around the center. Furthermore, a cylindrical oscillating shaft 9 that protrudes forward from the front surface of the mounting member 7 is inserted into an insertion hole 8a formed through the mounting plate 8 near a corner portion thereof, so that the mounting plate 8 is attached so as to be freely oscillating or rotatable in the vertical direction around the axis of the oscillating shaft 9. Therefore, the clamping means 3 swings in conjunction with the vertical swing of the mounting plate 8.

[0053] Furthermore, as shown in Figures 5 and 7, the rib-shaped protrusions constituting the claw portions 321c, 322c are each configured so that their thickness (wall thickness) gradually increases from the center C toward both left and right ends. With regard to the rib-like protrusions constituting the claw portions 321c, 322c, at least one of them can be configured so that its thickness (wall thickness) gradually increases from the center C toward both the left and right ends, but preferably both are configured so that their thickness (wall thickness) gradually increases from the center C toward both the left and right ends (for example, approximately 1.1 to 3 times that of the center C, more preferably approximately 1.5 to 3 times, and even more preferably approximately 2 to 3 times). With this configuration, it is possible to easily grab (hold) the abdominal fat while preventing damage to the inside of the carcass on which the abdominal fat is attached. In this embodiment, the rib-like protrusions constituting the claws 321c, 322c are each configured so that the thickness of both left and right end edges is approximately three times the thickness of the central portion C.

[0054] In the present invention, the device body 2 may be provided with a control means for controlling the lifting means 4 and the clamping means 3 . By utilizing this control means, for example, the clamping means 3 and the lifting means 4 can be controlled.

[0055] In this embodiment, the abdominal fat scraping device 1 further includes a device operating section 6 for performing an operation of peeling or scraping abdominal fat. 1 and 2, the device operation unit 6 is provided on the rear side of the device main body 2, and includes a handle 6a and a drive switch (not shown) for driving the abdominal fat scraping device 1. There are no particular limitations on the configuration or mounting position of the device operation unit, and an appropriately configured unit can be mounted in an appropriate position on the device body 2.

[0056] In this embodiment, the handle 6a has a pair of handles, one on the left and one on the right, each of which is provided with a drive switch (not shown), and is configured to be driven when these drive switches are pressed simultaneously. Therefore, the abdominal fat scraping device 1 is extremely safe.

[0057] An example of the abdominal fat scraping operation using the abdominal fat scraping device 1 according to the present invention will now be described in detail.

[0058] First, hold the handle 6a of the device operation part 6 and align the clamping piece 32 so that it touches the tip (lower end) of the abdominal fat adhering to the carcass (specifically, its inside).

[0059] Next, the drive switches provided on both the left and right ends of the handle 6a are simultaneously pressed to drive the abdominal fat scraping device.

[0060] That is, by driving the abdominal fat peeling device, the clamping piece 32 clamps the tip (lower end) of the abdominal fat with the upper clamping piece 321 and the lower clamping piece 322, and then, while maintaining that state, the swinging means 5 is used to swing or rotate either the left or right end of the clamping piece 32 upward, and in sync with this, the lifting means 4 is used to raise the clamping means 3. As a result, abdominal fat is peeled or stripped upwards. Therefore, peeling or stripping the abdominal fat is extremely easy and safe.

[0061] In this embodiment, by simply pressing and holding the drive switch, the clamping piece 32 clamps the abdominal fat, and the clamping means 3 swings or rotates and rises simultaneously. On the other hand, when the drive switch is not pressed, the clamping is released (i.e., the clamping pieces 321, 322 move apart), and the clamping means 3 descends and returns to its original position.

[0062] The abdominal fat removing device of this invention can be used to remove or strip abdominal fat from pig carcasses, but it can also be used to remove or strip abdominal fat from the carcasses of livestock other than pigs, such as beef carcasses. [Industrial Applicability]

[0063] The abdominal fat removal device of this invention makes it possible to easily and safely peel or strip the abdominal fat from the carcass of a livestock carcass for meat, in particular a pork carcass, by simply clamping the abdominal fat with its clamping means and then raising the clamping means, and is likely to be used in the industry that processes livestock carcasses for meat.
