Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a cutting device with an auxiliary blade that cuts an object placed on a cutting board with a rotating circular blade to form a fillet.

[Prior Art] Conventionally, in order to obtain a large amount of fillets from cut objects such as fish and livestock, the cut objects are placed on a cutting board, and a rotating round blade moves relative to the cut objects. There have been proposed those which cut an object to be cut (JP-A-63-99194 and JP-A-62-119729).

[Problems to be solved by the invention] Such a conventional cutting device is
The circular blade is adjusted to move in contact with the cutting board.
However, in particular, when the object to be cut is hard such as semi-thawed fish, meat, etc., a large cutting reaction force is generated on the round blade and the cutting board. Therefore, if it is used many times, the round blade warps, the device body and the cutting board are deformed, and a gap is created between the round blade and the cutting board. Further, since the round blade and the cutting board move in contact with each other, the round blade may wear due to contact with the cutting board, or the cutting board may wear due to contact with the round blade to form a kerf. Further, the round blade is worn by cutting the object to be cut. Even in such a case, a gap is created between the round blade and the cutting board. Then, since there is a gap, an uncut portion corresponding to the gap is left in the cut object, and there is a problem that the fillet cannot be completely separated from the cut object.

Then, this invention aims at solving the above-mentioned problem, and there exists a cutting device which cuts off a fillet completely, without leaving an uncut part of a to-be-cut object.

[Means for Solving Problems] In order to achieve this object, the present invention has the following configuration as means for solving the problems. That is, a rotating round blade moves along a cutting board, cuts an object to be cut placed on the cutting board, and in a cutting device that forms a fillet, in contact with the round blade side surface on the fillet side, An auxiliary blade that moves together with the round blade and that cuts the uncut portion of the fillet by the round blade is swingably supported, and a spring that biases the blade edge of the auxiliary blade in the direction of contacting the cutting board is provided; This is the configuration of a cutting device with an auxiliary blade that cuts the uncut residue.

[Operation] The rotating circular blade moves along the cutting board and cuts the object to be cut placed on the cutting board. The auxiliary blade, which is in contact with the side surface of the round blade on the side of the fillet, is swingably supported and moves together with the round blade. At that time, the blade tip of the auxiliary blade, which is biased by the spring in the direction of coming into contact with the cutting board, moves while coming into contact with the cutting board, and cuts the uncut portion of the object cut by the round blade.

Next, the operation of the cutting device with an auxiliary blade of this embodiment will be described.

First, the fish F is placed on the cutting board 21, and the tip of the fish F is moved in the direction of arrow A in FIG. 4 by a distance corresponding to the width of the fillet Fa cut from the cutting edge 1a of the round blade 1. Next, when the chain 56 driven by a drive device (not shown) is moved in the direction of arrow B, the main stepped shaft 8 moves the rail 55 and the V groove rail 52.
Guided by the ball-inserted wheels 32 and 40 and the V-shaped wheel 36 which are brought into contact with and roll, they move in the arrow B direction. With this,
Secondary stepped shaft connected to the main stepped shaft 8 by the connecting members 30 and 38
45 is guided by ball-inserted wheels 47, 49 and V-shaped wheel 48 which also roll in contact with the rail 55 and the V-groove rail 52, and moves in the direction of arrow B. Further, the gear 43 is mounted on the rack 50.
And rotates in the direction of arrow C. Further, the gear 2 rotates in the direction of arrow D, and thus the round blade 1 also rotates in the direction of arrow D. Therefore, the circular blade 1 rotates in the arrow D direction while moving in the arrow B direction.

On the other hand, the main stepped shaft 8 and the sub-stepped shaft 45 have flat portions 8c and 45b, respectively.
The rotation is prevented by the connecting member convex portion 30a of the connecting member 30, and the auxiliary blade 18 moves together with the main stepped shaft 8, that is, the round blade 1 in the arrow B direction but does not rotate.

The cutting edge 1a of the circular blade 1 that moves while rotating contacts the fish F at the cutting edge position E to cut the fish F. Edge of round blade 1
At the time of assembling, 1a of the round blade 1 is assembled so that the cutting edge 1a of the round blade 1 contacts the cutting board 21, so that the fish Fa is completely cut into the fillet Fa. However, during repeated cutting, the round blade 1 warps, the device body (not shown) and the cutting board 21 are deformed, and are worn, so that a gap is created between the cutting edge 1a and the cutting board 21. At this time, the blade edge of the plate 21 and the round blade 1 only with the round blade 1
A portion of the fish F can be left uncut depending on the gap formed between the fish F and 1a.

Therefore, when the round blade 1 moves along the cutting board 21 to cut the fish F, the spring 15 urges the cutting edge 18a of the auxiliary blade 18 to contact the cutting board 21 via the frame 12. Then, in the state of the chain double-dashed line in FIG. 1 so that the cutting edge 18a of the auxiliary blade 18 contacts the cutting board 21, the auxiliary blade 18 moves while contacting on the cutting board 21 to completely cut the uncut portion.

The round blade 1 and the auxiliary blade 18 that have completely cut the fish F and moved in the direction of the arrow B in FIG. 4 move along the rail 55 and the V-groove rail 52, draw an elliptical locus, and then return to the original shape. Return to the position. At this time, when the blade edge 18a of the auxiliary blade 18 is separated from the cutting board 21, the urging force of the spring 15 causes the auxiliary blade 18 and the frame 12 to swing in the clockwise direction of FIG. The swing is restricted, and the state is shown by the solid line in FIG.

By the time the round blade 1 and the auxiliary blade 18 return, the fish F is moved in the direction of arrow A in FIG. , Again cut into fillets Fa. The above operation is repeated and fish F is a fillet.
It is completely cut off by Fa one after another. Also, during cutting,
Since the auxiliary blade 18 is in contact with the side surface of the round blade 1, the cut fillet Fa is separated from the side surface of the round blade 1, and the fillet Fa is attached to the side surface of the round blade 1 by the fat content or the like attached to the side surface of the round blade 1. It prevents the round blade 1 from being cut off by the centrifugal force of the round blade 1 when it is adhered and pulled.

As described above, as described above, in the cutting device with the auxiliary blade of the present embodiment, the circular blade 1 moves along the cutting board 21 while rotating, and the auxiliary blade 18 abutting the fillet Fa side of the circular blade 1 cuts the cutting board. Move to 21.

Therefore, according to the cutting device with an auxiliary blade of the present embodiment,
The round blade 1 cuts the fish F, and the uncut portion of the fish F by the round blade 1 cuts by the auxiliary blade 18 that contacts the cutting board 21, so even if there is a gap between the cutting board 21 and the round blade 1, the fish F will be cut into pieces. The Fa is completely cut off, and the fish F is surely cut into the fillet Fa. Also,
It is possible to prevent the fillet Fa from being cut off by the centrifugal force of the round blade 1.

The object to be cut is not limited to the fish F as in the present embodiment,
For example, it can be used for meat such as meat and ham.

The embodiment of the present invention has been described above.
It is needless to say that the present invention is not limited to such an embodiment, and can be implemented in various modes without departing from the gist of the present invention.

[Advantage of the Invention] As described in detail above, according to the cutting device with an auxiliary blade of the present invention, the auxiliary blade completely cuts the uncut object of the round blade to form a fillet, and after cutting with the circular blade.
