Description

Device of cutting to a predetermined depth for meat and method therefor}

The present invention relates to a device for cutting the meat to a certain depth, more specifically, using a plurality of blades that move in the opposite direction at the same time, more specifically, a cut device for molding a plurality of sheaths of a predetermined depth on the upper surface of the meat It is about.

In meats such as beef or pork, they are cut in a certain direction for various purposes. In fact, if you make a rib in a restaurant on the market to provide to customers, it can be seen that the cut portion of the rib portion of the meat is made of a certain interval. Referring to FIG. 1, for example, cuts Ca and Cb having a shape intersecting with each other are formed in the meat M on the upper and lower surfaces of the meat M, respectively. Such a sheath is usually molded to a certain depth with respect to the thickness t of the meat.

This cut of meat is advantageous in two major ways. For example, in the case of cooking ribs, by forming a plurality of cuts as described above to a certain depth intersecting each other, there is an advantage that the rib seasoning is evenly cut in the meat. In addition, this sheathing is very effective in softening the meat. To cut meat and make meat softer means to cut the tendon or chewy parts of the meat into thin pieces, making the meat lighter.

However, the work to cut the meat in this way is currently dependent on the manual work of skilled workers. Cutting by hand is annoying, including not only having to rely on the skill of the operator to do all the work, but also the time problem that all meat must be performed by the hand of the worker.

Typically, meat is provided to a home in a state of being cut with a constant thickness t, as shown in FIG. 1, or to a restaurant. Since it is quite annoying to cut these meats manually by hand, there has been a demand for automating these cuts.

An object of the present invention is to provide an apparatus for inserting a sheath into meat having a certain thickness.

And another object of the present invention is to provide a device that can work uniformly in the most desirable form, such as spacing and depth of the sheath when the sheath into the meat.

According to the present invention, it will be possible to process a lot of meat in a very short time to cut the uniform and most desirable form of sheath.

Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

First, Figure 2 is an exemplary plan view for explaining the basic concept of the cut device according to the present invention.

As shown, the apparatus according to the present invention includes a plurality of blades (10a, 10b, ..., 10d) is connected to the connecting member 12, the first blade portion 10 and a plurality of blades ( 20a,..., 20d includes a second blade portion 20 configured to be connected to the connecting member 22. The plurality of blades 10a, 10b, ... 10e of the first blade portion 10 are arranged horizontally and have the same height as each other and are arranged at regular intervals. The plurality of blades 20a, ..., 20d of the second blade portion 20 also have the same height as the blades of the first blade portion and between the plurality of blades of the first blade portion 10. It is arranged to have a regular interval.

The plurality of blades provided on the first blade portion 10 and the second blade portion 20, respectively, have a sharp cutting edge at the lower end in order to cut the meat M actually placed on the lower surface thereof. And since the space | interval between each blade | wing of the said 1st blade | wing part 10 and the 2nd blade | wing part 20 becomes a space | interval of the sheath made in meat M, the spacing of the said blade is adjusted By doing so, it becomes possible to adjust the spacing of the sheaths formed on the meat.

Since the plurality of blades 10a, 10b, ... 10e of the first blade portion 10 are connected by the connecting member 12, the plurality of blades 10a, 10b, ... 10e are moved in the same direction. For example, when the connecting member 12 of the first blade portion 10 is repeatedly moved from side to side in the drawing, the plurality of blades 10a, 10b, ... 10e also have the same distance from side to side. It will move back and forth. In addition, since the plurality of blades 20a, ..., 20d of the second blade portion 20 are also connected by the connecting member 22, they move in the same direction. That is, when the connecting member 22 of the second blade portion 20 repeatedly moves at a predetermined interval from side to side in the drawing, the plurality of blades 20a,..., 20d also reciprocate from side to side with the same interval. Done.

And a plurality of blades (10a, 10b, ..., 10e) are provided in parallel to the first blade portion 10, and a plurality of blades (20a) are provided in parallel to the second blade portion (20) 20d) operates in opposite directions, as shown by thick black arrows A and B in FIG. For example, while the first blade portion 10 moves to the left as shown by arrow A in the drawing, the second blade portion 20 moves to the right as shown by arrow B in the drawing. On the contrary, while the first blade portion 10 moves to the right in the drawing, the second blade portion 20 moves to the left in the drawing.

In this way, the first blade portion 10 and the second blade portion 20 to move in the opposite direction to each other, since the meat in the frozen or thawed state is actually smooth, so that the blade in one direction to cut If only pushed, the meat is pushed along the direction. Accordingly, when the first blade portion 10 and the second blade portion 20 are cut while moving in the opposite direction in contact with the meat, the meat does not push in any direction, as shown in FIG. The same sheath can be made.

Therefore, when the first blade portion 10 and the second blade portion 20 reciprocate within each of the connecting members 12 and 22 within a predetermined distance a and b, the respective blades also reciprocate linearly. You exercise. In Figure 2, it can be seen that the movement of each of these blades is shown by the arrow. As can be seen in the portion shown in black in the lower arrow of Figure 2, when performing the reciprocating motion in a certain section (a, b), the blade and the second blade portion of the first blade portion 10 Each blade of 20 has a linear movement in the opposite direction, and all the blades have the same height, so that the meat M positioned below the blades is shaped as shown in FIG. will be.

Next, a device according to an embodiment embodying the above-described basic technical concept based on FIGS. 3 and 4 will be described.

The cutting device according to the present invention includes a fixed block 50 and a movable block 60 moving up and down at a predetermined interval with respect to the fixed block 50. The support shafts 52a and 52b are fixed to four corner portions of the fixing block 50 so as to stand upright. The upper portions of the support shafts 52a and 52b penetrate the moving block 60. Therefore, the movable block 60 is guided by the support shafts 52a and 52b, and is configured to be capable of descending and lifting within a predetermined range.

Elastic members such as coil springs 54a and 54b are installed on the outer circumferential surfaces of the support shafts 52a and 52b, and upper ends of the coil springs 54a and 54b are in contact with the bottom surface of the movable block 60. It is supported in a state. Therefore, when the moving block 60 is pressed downward, the coring springs 54a and 54b are compressed, and the moving block 60 is lowered.

Next, a configuration for lowering the mobile block 60 will be described. A pair of support brackets 56 are fixed to the right end portion of the fixed block 50 in the drawing. The support shaft 56 is provided with a handle shaft 58 rotatably around the hinge shaft 56a.

The handle shaft 58 is installed in a state extending along the upper portion of the moving block 50, and a handle portion 58b for holding by the user is installed at an end thereof. And the middle part of the handle shaft 58 is provided with a pressing member 58a made of, for example, a bolt and extending downward from the handle shaft 58. When the user rotates the handle shaft 58 clockwise about the hinge shaft 56a, the pressing member 58a presses the upper surface of the moving block 50. Therefore, the movable block 50 is lowered along the support shafts 52a and 52b penetrating at each corner. Of course, at this time the spring (54a, 54b) will be compressed by the moving interval of the moving block 50.

When the user releases the handle shaft 58, the movable block 50 moves upward by the elastic restoring force of the springs 54a and 54b to return to the original position.

The movement of the moving block 50 downward by the operation of the handle shaft 58, as described later, the first blade portion 10 and the second blade portion mounted on the lower surface of the moving block 50 As the operation 20 is performed, the operation for forming a sheath in the meat (M). This will be described later.

And, in order to control the bottom dead center of the moving block 60 to move downward by the operation of the handle shaft 58, the adjustment member 68 as shown in Figure 4 on the upper portion of the fixed block 50 It is installed. The adjusting member 68 is composed of a bolt member 68a, the outer peripheral surface of which is screwed, and a fixing member 68b of which the inner circumference of the bolt member 68a is screwed, as shown. Therefore, by adjusting the height by rotating the bolt member 68a it is possible to adjust the height of the bolt member 68 substantially.

When the moving block 60 descends by the above-described operation, and reaches a bottom dead center, the bottom surface of the moving block 50 hits the bolt member 68a, and the lowering stops. In this way, the lowering of the lowering means that the bottom dead center of the blade parts 10 and 20 provided on the lower side of the moving block 60 is determined. Therefore, the depth of the sheath of the meat formed by the blade portion (10, 20) can be adjusted. By using the adjusting member 68 in this way, it becomes possible to adjust the depth of the sheath made on the meat (M) placed on the top of the cutting board (64) at will.

And the upper side of the fixed block 50, the slide block 62 is installed to enable the sliding movement in the horizontal direction. The slide block 62 is provided with a cutting board 64 on the upper surface thereof, and meat M to be processed is placed on the upper surface of the cutting board 64. As the slide block 62 is shown by a dashed-dotted line, the slide block 62 can slide out of one side of the fixed block 50. Therefore, in the use of the apparatus according to the present invention, the meat M is placed on the upper surface of the cutting board 64 while the slide block 62 is pulled out to one side. In the state where the meat M is placed, the slide block 62 is pushed back into the position where the meat M can be processed, as shown by the solid line.

3, a plurality of needles Mh are provided on the upper surface of the cutting board 64. This needle (Mh), when the meat is placed on the cutting board 64, is a portion that performs the function of holding the meat so as not to move.

Here, it can be seen that the cutting board 64 is configured to be mounted on an upper portion of the slide block 62. However, it is also possible to actually configure the slide block 62 itself with a cutting board.

In summary, the meat M mounted on the slide block 62 installed on the upper side of the fixed block is mounted on the lower surface of the movable block 60 by the downward movement of the movable block 60. It will be appreciated that sheaths of a predetermined depth are made by the first and second blade portions 10 and 20.

Next, an embodiment for driving the first and second blades 10 and 20 when the moving block 60 descends will be described with reference to FIGS. 3 and 5.

In Fig. 5, reference numerals 12 and 22 denote connection members described with reference to Fig. 2. As described above, the connection member 12 includes the first blade portion 10, and the connection member 22 includes the second blade portion 20. As shown in FIG. 2, a plurality of blades 10a, 10b,..., 10e are connected to the connection member 12 of the first blade unit 10, as shown in FIG. A plurality of blades (20a, ... 20d) are also connected to the connecting member 22 of the portion 20, the function and operation of each blade is as described in FIG. In FIG. 5, for convenience of illustration, the illustration of the blades connected to each connection member in a horizontal state is omitted.

The connecting member 12 is connected to a pair of rods 86a, and the pair of rods 86a are connected to a piston 86b. In addition, the connecting member 22 is also connected to the rod 85a through a pair of connecting brackets B, and the rod 85a is connected to the piston 85b. Each of the pistons 85b and 86b is provided inside the cylinder block 81 and is elastically supported forward by springs 85c and 86c, respectively.

The pistons 85b and 86b are configured to be in contact with the cams 85 and 86 from the front, respectively. Accordingly, it will be appreciated that the pistons 85b and 86b are elastically supported by the springs 85c and 86c and are configured to maintain contact with the cams 85 and 86 at all times.

The cams 85 and 86 are fitted to the rotating shaft 80 to maintain a fixed state. In summary, the pair of cams 85 are configured to interlock with the first connecting member 12 via the pair of rods 86a, and the other pair of cams 86 are formed of the rods 85a and It can be seen that it is configured to interlock with the connecting member 22 through the connecting bracket (B).

And the cam 85 and the cam 86 are being fixed to the said rotating shaft 80 so that each may have a 180 degree phase difference. Therefore, when the rotating shaft 80 rotates, the rod 85a in contact with the cam 85 and the rod 86a in contact with the cam 86 are linearly moved in different directions, respectively. That is, since the cam 85 and the cam 86 for converting the rotational movement of the rotary shaft 80 into linear motion have a phase difference of 180 degrees, respectively, the piston 85b, which is in contact with the cams 85 and 86, In the linear motion of 86b), the direction is reversed. For example, when the piston 85b moves forward when the cams 85 and 86 rotate by the rotation of the rotary shaft 80, the piston 86b moves backward. Since the respective pistons 85b and 86b are configured to be in close contact with the cams 85 and 86 by springs 85c and 86c inside the cylinder block 81, the respective pistons 85b and 86b. ) Is linear movement by the rotational motion of the cam is as described above.

Therefore, when the pistons 85b and 86b have different movement directions, respectively, and make linear reciprocating motions, the linear reciprocating motions are formed through the rods 85a and 85b, and thus, the first connection member 12 and the second connection member. Is passed to 22. Therefore, as a result, it can be seen that the first connecting member 12 and the second connecting member 22 perform a linear reciprocating motion having different movement directions.

The fact that the first connecting member 12 and the second connecting member 22 is a linear reciprocating motion with different movement directions, as shown in Figure 2, the blade (10a, 10b, ..., 10e) and the blade (20a, ..., 20d) means that the linear reciprocating motion to be staggered with each other. Therefore, the meat on the lower surface of each blade as described above in Figure 2 is not pushed to either side by the staggered movement of each blade, the sheath is made.

According to the above-described embodiment, cams 85 and 86 are used to linearly reciprocate the first connection member 12 and the second connection member 22 at regular intervals in a staggered direction. Able to know. However, it is obvious that many other modifications are possible in the configuration for linearly reciprocating the first connection member 12 and the second connection member 22 for a predetermined period. Instead of the cams 85 and 86, it is also possible to use a crankshaft which is eccentrically connected to portions of different phases on the rotating plate rotated by the drive source.

In addition, it is obvious that other modifications are possible for a person skilled in the art with respect to the technical components configuring the connecting members 12 and 22 to have a different direction of movement and to linearly reciprocate.

The transmission of power for the rotation of the rotary shaft 80 may use a chain driving method or a belt driving method for connecting the driving shaft Ms of the driving motor Ma and the rotating shaft 80. In the illustrated embodiment, the spline 84 provided at the end of the rotation shaft 80 and the spline 82 provided at the end of the drive shaft Ms are connected to each other in a chain to drive the Ma in the drive motor Ma. An example of transmitting power to the rotary shaft 80 is shown. In addition, many other modifications are also possible in the manner of transmitting power from the drive motor (Ma) to the rotary shaft (80). In addition to the chain driving method or the belt driving method described above, power transmission using a mechanical element such as a gear is also possible.

Next, another embodiment for linearly reciprocating the first blade portion 10 and the second blade portion 20 in a different section in a different direction will be described with reference to FIGS. 7 and 8.

As shown in the drawing, the present embodiment is for linearly reciprocating the first connection member 12 and the second connection member 22 in a predetermined section, and shows an embodiment using a crank shaft.

The cam member 90 is connected to the output shaft Ms of the drive motor Ma. Since the cam shaft Sa protruding outward from the cam member 90 is eccentric with the output shaft Ms, the cam shaft Sa rotates the output shaft Ms when the driving motor Ma is rotated. It will rotate around the center. The crankshaft 91 is connected to the camshaft Sa via a bearing 92. The other end of the crankshaft 91 is connected to the shaft 93 of the swinging member 94 through a bearing 95.

The swinging member 94 is rotatably supported through a hinge shaft 94a of the center portion, and is connected to a pair of rods 96a and 96b above and below the hinge shaft 94a. The rods 96a and 96b are coupled to the long holes 94b formed in the swinging member 94 through pins 94p, respectively. The rods 96a and 96b are supported in the horizontal direction by guide holes 95a and 95b formed in the horizontal direction in the rod guide block 95.

Therefore, when the swinging member 94 swings within a predetermined angle range around the hinge shaft 94a, the rods 96a and 96b reciprocate in a horizontal section for a predetermined period. This reciprocating motion will cause the first reciprocating member 12 and the second connecting member 22 to be linearly reciprocated, respectively, connected to the rods 96a and 96b.

The drive motor Ma is supported by the motor bracket Mb at the top of the moving block 60. One side of the hinge shaft 94a of the rocking member 94 is rotatably supported by the motor bracket Mb and the other side by a separate support bracket B. FIG.

Next, a driving state according to the present embodiment will be described. First, when the driving motor Ma is driven, the output shaft Ms rotates. By the rotation of the output shaft Ms, the cam shaft Sa of the cam member 90 makes a rotational movement about the output shaft Ms. Therefore, the crankshaft 91 connected to the camshaft Sa performs a reciprocating motion for a certain section. Then, the swinging member 94 connected to the other end of the crankshaft 91 is oscillated at a predetermined interval about the hinge shaft 94a. That is, the swinging member 94 is to perform a circular arc motion that is repeated within a certain angle range around the hinge axis (94a).

When the swinging member 94 swings about the hinge shaft 94a, the rods 96a and 96b respectively connected to the upper and lower portions of the hinge shaft 94a perform reciprocating motions in a predetermined section in opposite directions. It can be seen that the movement of the rod can be transmitted to the first connection member 12 and the second connection member 22 as it is. In this way, the driving after the first connection member 12 and the second connection member 22 is performed in the same manner as in the above-described embodiment, so that a predetermined sheath can be made to the meat M.

And blades 10a, 10b, ... 10e horizontally connected to the first connecting member 12 and blades 20a, ..., 20d horizontally connected to the second connecting member 22 It is as mentioned above that it is most preferable to have the same height mutually. It looks at the auxiliary configuration for supporting the blade in a horizontal state.

As can be seen with reference to Figure 6a, the blades (10a, ... 10e and 20a, ..., 20d) to perform a linear reciprocating movement on the lower surface of the moving block 60 moving up and down a certain interval It is preferable that guide members 92 and 94 for guiding are installed. The guide member 92 supports the end portions of the blades connected to the connecting members 12 and 22, and the guide member 94 is for guiding the middle portion of the blades.

As shown in FIG. 6B, when the guide member 92 is viewed from the front, a plurality of slits 92a are formed in the middle portion. The slit 92a is a plurality of blades are accommodated, and performs a linear reciprocating motion in a state supported therein. By the guide member 92, the ends of the plurality of blades are supported in a stable state, so that the linear reciprocating motion may be more stably performed.

6C shows a front view of the guide member 94. As shown in the figure, the guide member 94 formed in the intermediate portion of the movable block 60 is formed with a plurality of slits 94a in a state of opening downward. Therefore, since the plurality of blades are linearly reciprocated in a state in which a portion of the upper portion is accommodated in the slit 94a, the cutting operation of cutting the meat to a predetermined depth may be smoothly performed on the upper surface of the meat (M).

As described above, according to the present invention, the plurality of blades 10a, .., 10e of the first blade portion 10 and the plurality of blades of the second blade portion 20 alternately arranged on the blade ( It can be seen that the basic technical idea is that 20a, ..., 20d) are configured to perform a linear reciprocating motion in opposite directions.

Within the scope of the basic technical idea according to the present invention, of course, many other modifications are possible to those skilled in the art.

According to the present invention constituted as described above, it is possible to provide a device that is easy to mold the sheath having a constant interval to the meat at a constant depth. The use of the device according to the invention therefore makes it possible to mold the sheath of the desired shape to a large amount of meat in a relatively fast time. In addition, the depth of the sheath can be adjusted at will, and the convenience of being able to arbitrarily adjust the spacing of the sheath can be expected.
