DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically cutting a streak attached to a bird's bamboo meat.

[0002]

2. Description of the Related Art Chicken bamboo meat has a relatively large streak at one end, so that it is not necessary to cut the above streak when the meat is distributed as meat. Conventionally, as described above, the streaks attached to the bird's bamboo meat have been cut out one by one manually using a kitchen knife, but the work was very troublesome and time-consuming.

[0003]

As described above, since the cutting of the streak on the bamboo meat of birds is a very time-consuming operation, the development of an apparatus capable of automatically removing the streak on the bamboo meat is developed. However, it was difficult to cut the streaks attached to bamboo meat with a machine cleanly, and it was never put to practical use. SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus capable of beautifully cutting a streak on a bamboo meat of a bird with a reasonable structure.

[0004]

In order to achieve the above-mentioned object, a bamboo cutting device for bamboo meat according to the present invention is constructed such that a plurality of tray bodies on which bamboo meat is placed are connected endlessly and are rotatably driven. Transport path, and a slitting mechanism installed in a fixed state at a position directly above the transport path, and a recess for placing bamboo meat in an unfolded state is provided on each tray body of the transport path. At the same time, a streak receiving portion for placing a streak attached to the end of bamboo meat on one end side of the placing recess is formed so as to substantially match the upper surface level of the placing recess, and the streak placed on the streak receiving portion is attached and detached. A plate-like cutting blade that holds a holding member that can be pressed as possible on the tray body and that holds the holding member horizontally at the position corresponding to one end of the tray body mounting recess toward the start end of the transport path. At a level slightly lower than the upper surface of the mounting recess. At the same time, a press roller is disposed directly above the gap with a gap corresponding to the thickness of the streak, and a rotary blade is vertically arranged at the other end of the parting blade, and the cutting edge is at the level of the parting blade. They are joined.

[0005] Further, it is preferable that a guide groove is formed in one end of the mounting recess of each of the tray bodies so that the one edge of the parting blade can be horizontally inserted.

[0006]

According to the above-mentioned means, a straightening mechanism is fixedly provided immediately above a transport path formed by connecting a number of tray bodies and having an endless shape. The scoring mechanism includes a cutting blade for separating the muscle from the bamboo meat, a rotary blade for cutting the base of the separated muscle, and a pressing roller for pressing the bamboo meat from above during the cutting of the muscle.

[0007] Bamboo meat is placed in an unfolded state in the placement recess of each tray body in the transport path, and a streak attached to an end of the meat is stretched and placed on the streak receiving portion. The presser piece provided on the tray presses the streak placed on the streak receiving portion from above as described above. Due to the rotation drive of the transport path, the tray body on which the bamboo meat is placed moves on the transport path, and when passing through the above-described slitting mechanism, the pressing roller rides on the end of the bamboo meat placed on the tray body. Press down into the mounting recess.

At the same time, the tip of the parting blade is inserted between the streaked meat and the streaked meat, which is raised to a level substantially matching the upper surface level of the mounting recess of the tray body, thereby separating the streaked meat. Further, the rotary blade rotating at the other end of the parting blade cuts the base of the streaks separated from the bamboo meat by the cutting edge joined to the parting blade level.

Also, in the tray body in which a guide groove into which one edge of a parting blade is horizontally inserted is formed at one end side of the mounting recess of the tray body, the tray body on which bamboo meat is placed is provided with a slitting mechanism. When passing through, the one edge of the parting-off blade is inserted and guided in the guide groove of the moving tray body, and the blade is prevented from running when cutting the streaks.

[0010]

Since the present invention is constructed as described above, bamboo meat is placed in an unfolded state on a tray body of a transporting path which is driven to rotate, and a streak attached to the end of the meat is formed at the streak receiving portion. By simply placing the tray on top, it is possible to separate the streaks from the bamboo meat on the tray body and then cut the streaks from the base of the streaks while the tray body is moving, and remove the streaks as well as the manual work. Therefore, it is possible to automate the cumbersome work of removing bamboo streaks, which has conventionally been performed manually, thereby saving labor.

Also, in the case where a guide groove into which one edge of a parting blade is horizontally inserted is formed at one end of the mounting concave portion of the tray body, when cutting a streak of bamboo meat, the parting is performed. One edge of the blade is inserted into the guide groove of the tray body that moves relatively, and the blade edge can be guided to a level slightly lower than the upper surface level of the mounting recess. And accurately prevent insertion of the blade at the time of cutting, thereby making it possible to more reliably cut and separate the streaks.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. The bamboo cutting device shown in FIG. 1 to FIG.

The tray body 11 is a plate-like body on which bamboo meat is placed in an unfolded state. The tray body 11 is formed in a rectangular shape having a length substantially equal to the width of the transport path 1, and two rollers 15 are provided at both ends thereof. Installed. In the forward path and the return path of the transport path 1, the positions where the rollers 15 at both ends of each tray body 11 pass are:
Guide rails 25 on which the rollers 15 ride and run are provided vertically parallel, and attached and fixed to both sides of the base frame 20. As a result, the rollers 15 provided at both ends of each tray body 11 travel along the guide rails 25 while the transport path 1 is rotating, so that each tray body 11 is horizontal and return on the forward path and the return path of the transport path 1. It is configured to move linearly.

A sprocket 26a is attached to one end of the rotating shaft 22b at the end of the conveying path 1. The sprocket 26a is connected via a chain 26c to a sprocket 26b attached to an output shaft of a drive motor 27 installed below the base frame 20. Therefore, when the drive motor 27 is driven, the rotation shaft 22b of the transport path 1 rotates, and each tray body 11 connected endlessly by the chain name 26 rotates and moves along the elliptical orbit.

As shown in FIGS. 4 to 8 and 9, the tray body 11 includes a tray plate 12 on which bamboo meat is placed and a substrate 13 for mounting and supporting the tray plate 12. The tray body 1 is formed of, for example, a synthetic resin material, and has a mounting concave portion 12a on the upper surface thereof for unfolding and mounting bamboo meat. The mounting recess 12a is formed at a depth corresponding to the average thickness of the bamboo meat, and a streak receiving portion 14 is formed at one end thereof. The streak receiving portion 14 is a portion on which a streak attached to one end of the bamboo meat placed on the placing recess 12a is placed, and the tray plate 1
2 is formed as a groove at one end, and the level of the concave surface receiving the streaks is made substantially coincident with the upper surface level of the mounting concave portion 12a. Accordingly, the streaks of bamboo meat placed in a state of being deployed in the placement recess 12a maintain a state of being stretched horizontally at the upper surface level of the recess 12a.

The substrate 13 for mounting and supporting the above-mentioned tray plate 12 is a rectangular plate formed to be slightly larger than the tray plate 12, and is provided with two rollers 15 at both ends so as to project the rollers 15 described above. At the same time, both chains 24 described above are fixed to the lower surface. The tray plate 12 is mounted and supported on the upper surface of the substrate 13, and a pressing piece 16 is provided at one end.
Is provided. The presser piece 16 presses the streaks of bamboo meat placed on the streak receiving portion 14 of the tray plate 12 from above as described above. The holding piece 16 is formed in a substantially square rod shape, and is supported at the upper end of a support 16a fixed to one end of the substrate 13 substantially at the center, and swings like a seesaw with the shaft support as a fulcrum. It is supported by. The holding piece 16
Of the tray plate 12 project downward, and come into contact with the streak receiving portion 14 of the tray plate 12 in a lowered state.
A roller 16a is pivotally supported at the rear end of the pressing piece 16. Therefore, the rear end of the presser piece 16 is lowered by the weight of the roller 16 to maintain the inclined state.

On the other hand, an engagement rail 17 is provided on one side of the forward path of the transport path 1 so as to extend along a guide rail 24. The engagement rail 17 is a member that constitutes a rail surface on which the roller 16a of the pressing piece 16 rides, and is provided in parallel with the transport path 1 in an area where the slitting mechanism 5 on the transport path 1 is provided.
It is mounted and supported on a member on the base frame 20 side. That is, when the roller 16a of the presser piece 16 that moves horizontally together with the tray body 11 moves to a range on the transport path 1 where the scoring mechanism 5 is provided, the roller 16a rides on the engagement rail 17 and moves to a position one step higher. It travels along with this, and the tip of the presser piece 16 descends on the streak receiving portion 14 to press down the streaks of the bamboo meat placed on the streak receiving portion 14 from above. Further, when the tray body 11 passes through the range of the above-described crease mechanism 5, the rollers 16
7 and descends again to the original height, and the pressing by the pressing piece 16 is released.

The scoring mechanism 5 installed on the transport path 1
The transport path 1 includes a belt roller 53 that presses the end of bamboo meat placed on the tray body 11, a cutting blade 51 that cuts a streak from the bamboo meat, and a rotary blade 52 that cuts the base of the streak. Arranged in the latter half on the outbound route,
It is attached and supported. The parting blade 51 is moved from the support member 51 b fixed on the base frame 20 to the transport path 1.
The blade is integrally attached to the front end of a support plate 51a extending toward the center, and the cutting edge protrudes toward the start end of the transport path 1.

The parting blade 51 is provided at one end of the mounting recess 12a of the tray body 11, that is, at a position corresponding to a streak portion of bamboo meat placed in the mounting recess 12 described above. The body 11 is held horizontally at a level slightly lower than the upper surface level of the mounting recess 12a (FIG. 7).
That is, when the tray body 11 of the feed path 1 moves horizontally, the parting blade 51 is inserted between the streak and the bamboo meat to cut both. The cutting edge of the cutting edge 51 is cut diagonally so that one end side protrudes. According to this,
As described above, when the parting blade 51 is inserted between the streak pressed on the streak receiving portion 14 and the bamboo meat, the streak is cut from the end of the bamboo meat toward the center,
The movement of the cutting edge can be performed in the same manner as in the manual operation, so that the streaks can be separated clearly.

Further, a guide groove 18 into which the edge of one end of the cutting blade 51 is inserted is horizontally formed in the end face of the mounting recess 12a of the tray body 11. According to the provision of the guide grooves 18 in the tray body 11 as described above, the tray body 11 on which one end edge of the parting blade 51 moves when the tray body 11 on which the bamboo meat is placed passes through the slitting mechanism 5. And is guided by being fitted in the guide groove 18 of the first embodiment. Therefore, the cutting edge of the parting blade 51 during cutting is held at a predetermined level so as not to be shaken, and the cutting edge can be accurately inserted between the meat and the streak, so that the streak can be reliably separated. .

When the streak blade 51 cuts the streak from the bamboo meat as described above, the belt roller 53 presses the bamboo meat placed in the placing recess 12a of the tray body 11 from the entire surface. The endless belt 53c is stretched between two rollers 53a and 53b provided at an interval in the front and rear to prevent the displacement of the meat. The rollers 53a, 53b are supported by shafts 54a, 54 extending horizontally from the upper portion of the base frame 20 toward the center of the transport path 1.
4b. The support shafts 54 a and 54 b are rotatably supported on a bearing plate 55 installed on the base frame 20, and are transported in the transport path 1 by a gear mechanism 56 that receives a driving force from the rotating shaft 22 b of the transport path 1. It is driven to rotate at the same speed as.

The belt roller 53 has a parting blade 51.
The tip is positioned somewhat forward of the cutting edge of the parting blade 51. Further, a gap corresponding to the thickness of the streak of the bamboo meat is provided between the lower surface of the belt roller 53 and the cutting edge 51 as shown in FIG. The cutting edge 51 is configured to cut under the above-mentioned streaks while holding the end of the cutting edge from above.

The rotary blade 52 cuts the base of the muscle separated from the bamboo meat by the parting blade 51 while being pressed by the belt roller 53 as described above, and completely cuts the muscle from the meat. Transfer path 1 from the top of frame 20
It is attached to the tip of a rotating shaft 63a that is supported by a bearing cylinder 63 that extends horizontally toward the center. In addition, the rotary blade 5
2 is directly connected to the output shaft of a drive motor 62 installed on the base frame 20 via a mount 61, and is rotated by the drive of the drive motor 62.

The rotary blade 52 is installed substantially at the center between the two rollers 53a and 53b of the belt roller 53 and at a position slightly behind the parting blade 51 in a vertical state. FIG.
As shown by, the lower end of the rotary blade 52, which is a blade edge position for cutting bamboo meat, is close to the other end side edge of the parting edge 51, and the level of the edge is the level of the parting edge 51. According to this, the streaks separated from the bamboo meat are cut from the base portion by the cutting edge of the rotary blade 52.

Next, the operation of the bamboo meat cutting apparatus constructed as described above will be described. The operator places the bamboo meat in a state where the bamboo meat is unfolded in the mounting concave portion 12a of the tray body 11 that is moved to the forward end of the forward path of the transport path 1 by the rotation drive of the transport path 1, and strikes one end of the bamboo meat. The muscle is stretched and placed on the muscle receiving portion 14. At this time, the tip of the holding piece 16 is
6, the muscle placed on the muscle receiving portion 14 has not been pressed yet (FIG. 9). The tray body 11 on which the bamboo meat is placed moves along the outward path by the rotation of the transport path 1. Then, when the tray body 11 approaches the breaking mechanism 5, the roller 16 a of the holding piece 16 runs on the engagement rail 17. As a result, the tip of the holding piece 16 descends, and holds down the streaks placed on the streak receiving portion 14 (FIG. 10).

When the tray body 11 on which the bamboo meat is placed moves on the transport path and engages the streaking mechanism 5, a belt roller 53 rides on the end of the bamboo body placed on the tray body, and the bamboo meat with a streak is formed. Press down on the end from above. At the same time, one edge of the parting blade 51 is inserted into the guide groove 18 of the tray body 11. Immediately thereafter, a sharp cutting edge is inserted between the streak and the bamboo meat in a state where the tip of the parting blade 51 is pulled up to the upper surface level of the mounting recess 12a, and the streak is separated from the meat. Further, the cutting edge of the rotary blade 52 rotating at the other end of the parting blade 51 cuts the base of the streaks separated from the bamboo meat. The cutting of the above-mentioned streaks is performed on the tray body 11 on which
Is carried out every time the sheet passes through the slitting mechanism 5.

When the tray body 11 obtained by cutting the streaks of the bamboo meat passes through the streaking mechanism 5, the roller 16a of the pressing piece 16 comes off from above the engaging rail 17, and the tip rises by its own weight to press the streaks. Is released. Since the streaks cut as described above remain on the streak receiving portion 14 of the tray body 11 or attached to the outer periphery of the belt roller 53, the operator removes the cut bamboo meat from the tray body 11 from the tray body 11. At the same time as picking up, collect the cut muscle. In the above embodiment, the cut streaks are manually collected. However, the cut streaks may be collected mechanically by blowing compressed air or using an air suction nozzle. .

In the above-described embodiment, the belt roller 53 is used as a pressing roller for pressing the bamboo meat when cutting the streak. However, the pressing roller is not limited to the above-mentioned one, and the pressing roller is not limited to the one described above. Any structure may be used as long as the bamboo meat can be pressed without shifting. Further, the presser piece 16 of the above embodiment presses the streaks on the streak receiving portion 14 only while the tray body 11 passes between the streak cutting mechanisms 5 by the rollers 16a riding on the engagement rails 17. It was configured to attach.
However, the operation mechanism of the holding piece is not limited to the above-described configuration.For example, the tip of the holding piece is always urged by a spring or the like in a descending direction, and the worker presses the holding piece at the start end of the transport path. May be lifted to hold the streak, and after cutting the streak, the holding piece is released at the end of the transport path to remove the streak.
