Japanese Unexamined Patent Publication No. 2005-111614

In the conventional knot cutting device, since a slit is formed in the side wall that separates the accommodation chamber and the transfer chamber, the knot shavings generated in the transfer chamber enter the accommodation chamber through the slit. There is a problem that it may adhere to the transmitter in the containment chamber and it takes time for maintenance such as cleaning.

The problem to be solved by the present invention is to use an actuator that has never been used in a knot cutting device instead of using a transmission body such as a belt or a chain and a transmission body drive motor that drives the transmission body. It is an object of the present invention to provide a knot cutting device that is easier to maintain such as cleaning than a kind cutting device.

The knot cutting device of the present invention is a device for cutting knots with a rotary blade to produce shavings, and includes a main body having a cutting chamber and a motor chamber, which is partitioned by a partition body having no opening such as a slit. ing.

In the following, the front and back are represented with reference to the moving direction of the node F, and the front in the moving direction at the time of cutting is referred to as the front and the rear is referred to as the back.

As an example, the main body 1 shown in FIG. 1 includes an upper cutting chamber 1a and a lower motor chamber 1b. The cutting chamber 1a and the motor chamber 1b are partitioned by a partition body (bottom plate of the cutting chamber 1a) 1c having no openings such as slits and holes. A wiring chamber 1d is provided below the motor chamber 1b. The cutting chamber 1a is provided with an upper surface opening, and the main body 1 is provided with a lid 11 for opening and closing the upper surface opening rotatably. The lid 11 is provided with a handle 11a used when opening and closing.

The knot cutting device of the present invention is set so as not to operate when the lid 11 is open. In this embodiment, a lid detection sensor 12 for detecting that the lid 11 is closed is provided on the peripheral wall on the upper end side of the cutting chamber 1a, and a corner portion of the lid 11 (the lid detection sensor 12 when the lid 11 is closed) is provided. A covering portion 11b is provided on the portion (the portion that covers the portion). On the contrary, the cover portion 11b may be provided on the cutting chamber 1a side, and the lid detection sensor 12 may be provided on the lid 11 side. In this embodiment, a transparent window 11c such as a glass plate or an acrylic plate is provided in a part of the lid 11 so that the inside of the cutting chamber 1a can be visually recognized from the outside. The main body 1 may be provided with an adjuster 1e for height adjustment as shown in FIG. 1, if necessary. The main body 1 described here is an example, and a structure other than this can be adopted.

The linear base 2 is a rail member for moving the slider 3. As the linear base 2 and the slider 3, commercially available actuators (for example, IS series actuators of IAI Co., Ltd.) can be used. In this embodiment, the slider 3 is moved by air supplied from a compressor (not shown). The linear base 2 and the slider 3 referred to here are the slide mechanisms described in the claims.

The slider 3 is provided with a detected body 3a (FIGS. 3A and 3B). The detected body 3a is the upper surface of the partition body 1c and passes above the detection unit of the detection sensor 21 (FIG. 3A) provided between the linear base 2 and the moving passage 6. .. When the object to be detected 3a reaches above the detection sensor 21 with the forward movement of the slider 3, the forward movement of the slider 3 is stopped and switched to the backward movement. The detected body 3a can also be provided on the attachment 4 or the node holder 5. In either case, the detected body 3a is provided at a position that covers the upper side of the detection unit of the detection sensor 21. In the present invention, by providing the detection sensor 21, it is possible to reliably prevent the node F from being overcut and the node holder 5 from coming into contact with the rotary blade 7. The slider 3 has a speed of backward movement (hereinafter referred to as "return speed") faster than that of forward movement during cutting so as not to cause a loss of time.

The linear base 2 and the slider 3 described here are examples, and those having other structures may be adopted. Although not shown, an air ejection means (not shown) is connected to the linear base 2, and the air ejected from the air ejection means causes shavings in the cutting chamber 1a to be removed from the linear base 2 by the slider 3. It is designed to prevent it from adhering to such things.

An attachment 4 is attached to the upper surface of the slider 3. The attachment 4 is a member for fixing the knot holder 5. As an example, the attachment 4 shown in FIG. 1 has a plan-viewing clove shape, and two mounting pieces 4a are projected downward on the bottom surface. One knot holder 5 is attached to each attachment piece 4a. The attachment 4 and the node holder 5 move in the same direction as the slider 3 moves in the front-rear direction. The attachment 4 described here is an example, and an attachment 4 having a structure other than this can be adopted.

The knot holder 5 is a chuck member that holds the knot F to be cut. As an example, the node holders 5 shown in FIGS. 3 (a) and 3 (b) are provided on the lower holding body 5a fixed to the mounting piece 4a of the attachment 4 and on the upper side of the lower holding body 5a. The upper holding body 5b is provided. The lower holding body 5a and the upper holding body 5b are configured so that the tip side approaches and separates from each other. The tip end side of the upper holding body 5b is in contact with the tip end side of the lower holding body 5a when the node F is not held. A handle bar 5c is provided on the upper holding body 5b, and by tilting the handle bar 5c to the rear side, the tip end side of the upper holding body 5b is separated from the tip end side of the lower holding body 5a (on the tip side of both). The interval is widened). The knot holder 5 may be fixed directly to the slider 3. In this case, the attachment 4 can be omitted. The knot holder 5 described here is an example, and one having a structure other than this can be adopted.

The movement passage 6 is a passage through which the node F held by the node holder 5 moves. The moving passages 6 are provided in one row on each side of the linear base 2 in the width direction (two rows in total). The moving passages 6 may be in one row or in three or more rows. As an example, the moving passage 6 shown in FIGS. 3A and 3B is a recess of a gutter-shaped member having two side walls 6a and 6b and a grounding surface 6c, specifically, the side walls 6a and 6b and a grounding surface. It is provided in the portion surrounded by 6c. The side wall (hereinafter referred to as "inner side wall") 6a on the linear base 2 side of the gutter-shaped member is erected vertically or substantially perpendicular to the ground contact surface 6c, and the other side wall (hereinafter referred to as "outer wall surface") 6b is the ground contact surface. It stands diagonally outward with respect to 6c. The inner side wall 6a and the outer wall 6b are configured to have a V shape in which the lower side is narrow and the upper side is wide when viewed from the rotary blade 7 side. Since at least two points of the node F are supported by the V-shape in this way, there is an advantage that the node F is more likely to be stable than when it is placed on a flat surface. The gutter-shaped member constituting the moving passage 6 is attached to the partition body 1c so as to move in the front-rear direction and adjust the position. The moving passage 6 may be made of a member other than the gutter-shaped member. The moving passage 6 can also be configured without using a member.

A flat plate-shaped mounting body 6d (FIG. 3A) is provided on the outside of the inner side wall 6a (on the linear base 2 side). The mounting body 6d is provided with an elongated hole (not shown) in the front-rear direction. A gap adjusting member 6e for adjusting a gap with the rotary blade 7 is attached to the mounting body 6d. The gap adjusting member 6e is attached to the mounting body 6d by a stopper (not shown) inserted into the long hole of the mounting body 6d, and is moved back and forth within the range of the long hole to move the position in the front-rear direction. It can be adjusted. By moving the gap adjusting member 6e, the gap between the gap adjusting member 6e and the rotary cutting tool 7 is adjusted. Since the rotary blade 7 is a consumable item and wears due to use, it is necessary to adjust the gap as appropriate. Further, when replacing the rotary blade 7 with one having a larger diameter or a smaller diameter than the one in use, it is necessary to adjust the gap.

As shown in FIGS. 3A and 4A, a holding piece 13 for suppressing the lifting of the node F in contact with the rotary cutting tool 7 is provided at a position closer to the tip of the outer wall 6b. In this embodiment, the knots F are supported at three points by the side walls 6a and 6b and the holding piece 13, and can be moved in a stable state. The holding piece 13 is provided on a rotating shaft 14 rotatably fixed to the outer wall 6b. An urging spring 16 is provided on the outer periphery of the rotating shaft 14. One end of the urging spring 16 is addressed to the surface of the holding piece 13 on the rotary blade 7 side. As a result, the holding piece 13 is urged to the knot holder 5 side when the knot F is not touching.

An arm 15 is provided so as to project from the outer periphery of the upper side of the rotating shaft 14. As an example, the arm 15 shown in FIGS. 1 to 5 includes a base piece 15a parallel to the rotation axis 14 and a curved piece 15b erected perpendicularly to the base piece 15a. The curved piece 15b is formed by bending the outer end portion of the base piece 15a. In this embodiment, a speed switching sensor 17 (FIGS. 5A and 5B) is provided on the outer surface of the outer wall 6b, the arm 15 rotates with the rotation of the rotating shaft 14, and the curved piece 15b thereof is the speed switching sensor. When it overlaps with the detection unit of 17, the moving speed of the slider 3 is switched (slowed down).

Specifically, the slider 3 has a moving speed (hereinafter referred to as "initial speed") from the initial position (position shown in FIGS. 1 and 3A) until the curved piece 15b overlaps the detection unit of the speed switching sensor 17. ) Is fast, and the speed is slower than the initial speed (hereinafter referred to as "cutting speed") from the time when the curved piece 15b overlaps the detection unit of the speed switching sensor 17 until the speed is switched to the backward movement after the cutting is completed. .. By doing so, it is possible to eliminate the loss of the moving time until the cutting is started and to prevent the overload on the rotary cutting tool 7 at the time of cutting.

The rotary blade 7 cuts the node F. As the rotary blade 7, an existing one (for example, the one shown in Patent Document 1) can be used. The rotary blade 7 is rotatably mounted on the blade mounting shaft 18. The rotary blade 7 is designed to be replaced. The rotary blade 7 is arranged on the front side of the moving passage 6 so that the node F that has moved forward in the moving passage 6 can be cut.

The transmission mechanism 8 is a mechanism for transmitting the power of the rotary blade motor M to the rotary blade 7. As an example, the transmission mechanism 8 shown in FIG. 1 includes a first pulley 8a attached to an output shaft S of a rotary blade motor M, a second pulley 8b attached to a blade mounting shaft 18, a first pulley 8a, and a second pulley. A transmission belt 8c is provided around the outer periphery of the 8b. An existing timing belt or the like can be used for the first pulley 8a and the second pulley 8b, and an existing timing belt or the like can be used for the transmission belt 8c. A bearing 19 is provided in the middle stage of the blade mounting shaft 18 so that the blade mounting shaft 18 rotates smoothly. Two or more bearings 19 may be provided on each blade mounting shaft 18. Bearing 19 can be omitted if it is not needed. The tip end side of the blade mounting shaft 18 penetrates the partition body 1c and projects toward the cutting chamber 1a, and the rotary blade 7 is rotatably attached to the protruding portion. Although not shown, a spacer for height adjustment is provided on the lower side of the rotary cutting tool 7.

The recovery case 9 is a case for recovering the cut bonito flakes. As an example, what is shown in FIG. 1 is a cube with an upper surface opening (not shown). The inside of the storage case 9 is vertically divided by a single perforated plate 20. The upper space (hereinafter referred to as "upper collection chamber") 9a is the part where shavings are housed, and the lower space (hereinafter referred to as "lower collection chamber") 9b is the part where cutting pieces and shavings finer than the set size are collected. be. Although not shown, the lower collection chamber 9b is provided with a drawer so that cutting pieces and the like can be collected in the drawer. The collection case 9 can be placed on a case mounting portion (not shown) provided on the main body.

In this embodiment, the recovery case 9 is made of a transparent material (acrylic plate or glass plate) so that the state in which the shavings are recovered can be visually recognized from the outside. By doing so, it can be used as a device for demonstration in a store or the like. The recovery case 9 can also be made of an opaque material.

The introduction hood 10 is a member for introducing the cut bonito into the recovery case 9. As an example, the introduction hood 10 shown in FIG. 1 has a cylindrical shape having an inlet on one end side and an outlet on the other end side. By arranging the inlet on the cutting chamber 1a side and the outlet on the upper surface opening side of the recovery case 9, the passage from the cutting chamber 1a to the recovery case 9 is communicated. The shavings cut in the cutting chamber 1a reach the recovery case 9 through the introduction hood 10. Of the opening on the upper surface of the recovery case 9, the portion without the introduction hood 10 is closed with an upper lid (not shown) so that the bonito flakes do not scatter outside the recovery case 9.

The controller C sets the rotation speed of the rotary blade 7 and the movement speed (initial speed, cutting speed, return speed) of the slider 3. No two clauses F are the same, and there are individual differences. Therefore, even if a certain knot F can produce a kezuri-bushi of an appropriate size, another knot F may not have a kezuri-bushi of an appropriate size. This is a problem caused by the difference in the amount of water and the hardness contained in the node F.

In the present invention, the rotation speed of the rotary blade 7 and the movement speed of the slider 3 can be set to a speed suitable for each node F by the controller C. The bonito flakes become thinner when the rotation speed (rotation speed per unit time) of the rotary blade 7 is increased, and become thicker when the rotation speed is decreased. Further, the kezuri-bushi becomes thicker when the cutting speed of the slider 3 is increased, and becomes thinner when the cutting speed is decreased. In this embodiment, the rotation speed of the rotary cutting tool 7 can be set in the range of 0 to 2800 rpm, and the cutting speed can be set in the range of 0.1 to 2.0 m / sec. The numerical values shown here are examples, and other numerical values are not excluded.

Although not shown, the controller C of this embodiment is provided with a display screen, a power button, an abnormality release button, a feed (forward / backward) button, an operation button, and a stop button. The power button, abnormality release button, feed (forward / backward) button, operation button, and stop button are provided at the bottom of the display screen. The design of the controller C may be other than this.

The configuration shown in the embodiment is merely an example, and the knot cutting apparatus of the present invention is not limited to the configuration shown in the embodiment. Further, the configuration of the above-described embodiment can be appropriately changed or omitted as long as the operation and effect of the knot cutting device of the present invention are exhibited.

The knot cutting device of the present invention can be widely used for cutting various katsuobushi F such as dried bonito, mackerel katsuobushi, and processed katsuobushi.
