  Next, the attachment / detachment mechanism of the screw rod advance / retreat mechanism 13 will be described with reference to FIGS. FIG. 9 is a perspective view showing the food spiral cutting device according to the first embodiment, and FIG. 10 is an exploded perspective view showing a detachable state of the screw rod advancing / retreating mechanism of FIG.

  As shown in FIGS. 9 and 10, the screw rod advance / retreat mechanism 13 is configured to be detachable from the support base 11. Specifically, in the width direction on the other side of the support base 11, as shown in FIG. 10, two bolts 27, 27 are planted at regular intervals. Further, the cover frame 14 of the screw rod advance / retreat mechanism 13 has a seat plate 28 fixed to the bottom surface thereof as shown in FIG. At both ends of the seat plate 28, extension portions 28a are formed so as to extend from the cover frame 14 in the width direction of the support base 11 when the cover frame 14 is attached to the support base 11, respectively. The extension portions 28a are formed with insertion holes 28b and 28b through which the bolts 27 and 27 are inserted, respectively. Therefore, the cover frame 14 is fixed by inserting the insertion holes 28b, 28b into the bolts 27, 27 and tightening the nuts 29, 29 with knobs.

  And in order to attach the cover frame 14 to the support stand 11, after inserting the insertion holes 28b and 28b formed in the extension part 28a of the seat board 28 in the volt | bolts 27 and 27 currently planted in the support stand 11, the bolt 27 , 27 by tightening nuts 29, 29 with knobs, respectively. On the other hand, in order to remove the cover frame 14 from the support base 11, the nuts 29 and 29 with knobs are loosened and removed, and then the cover frame 14 is lifted upward to form an extension 28 a of the seat plate 28 from the bolts 27 and 27. This is done by removing the inserted insertion holes 28b, 28b. Since the cover frame 14 is configured to be detachable from the support base 11 in this manner, it can be easily replaced with another screw rod advance / retreat mechanism 13 to which the screw rods 23 having different screw pitches are attached.

  On the other hand, the blade 12 includes a washer 30, a support protrusion 31, a cutting blade 32, and a long rod-shaped body 33 as a support member formed integrally with the support protrusion 31, as shown in FIGS. .

  The washer 30 is formed in a rectangular plate as shown in FIGS. 9 to 11, and a corner of the washer 30 extends to form a circular mounting hole 30a. The support protrusion 31 is a solid round bar that is formed in a pointed shape and has a length of, for example, 11 mm. The support protrusion 31 protrudes from the holding plate 25 so that the axis of the screw bar 23 coincides with the axis. The support protrusion 31 and the rod-shaped body 33 are inserted into the mounting hole 30a, and are fixed to the opening edge of the mounting hole 30a by welding. The support protrusion 31 pierces the other end portion of the potato P and sandwiches the potato P with the holding plate 25.

  The washer 30 is fixed to the blade 12 with screws. A thin plate-like cutting blade 32 is fixed to the washer 30 at a position where a part of the blade edge 34 contacts the outer peripheral surface of the support protrusion 31 by welding. As shown in FIGS. 11 and 12, the cutting blade 32 is formed in a sine wave shape in a side view by forming a plurality of concave and convex portions 35 on the blade tip 34 along the length direction. These uneven portions 35 are sequentially formed in an arc shape in a direction away from the support protrusion 31, and are formed concentrically with respect to the support protrusion 31.

  The cutting blade 32 is formed on the side opposite to the direction in which the support protrusion 31 protrudes, and the potato P is cut in a spiral shape along the axial direction while leaving the central portion from the outer peripheral direction toward the center. Cut in a sine wave cross section in the radial direction.

  As shown in FIGS. 4 and 9, the rod-shaped body 33 is a solid round bar having a length of 135 mm and a diameter of 3 mm, for example. The rod 33 protrudes from the vicinity of the cutting blade 32 on the side opposite to the direction in which the support protrusion 31 protrudes, and supports the potatoes P that are spirally cut and fed through the opening 36 that opens around the cutting blade 32. . Here, since the rod-shaped body 33 is formed integrally with the support protrusion 31, the rod-shaped body 33 protrudes from the support protrusion 31 so that the screw rod 23 and the shaft center coincide with each other.

  In addition, the length of the rod-shaped body 33 can be appropriately changed depending on the length of the workpiece in the axial direction. Moreover, the diameter of the rod-shaped body 33 is set in order to make the hole formed at the center of the potato P cut into the strength and the spiral cut as much as possible.

  Furthermore, as shown in FIGS. 9 and 10, the blade 12 is fixed to the upper part of the outer periphery and both sides of the outer periphery so that the reinforcing angle 37 protrudes to the front side. In addition, the blade 12 is provided with a hood portion 38 on the rear side. Thus, by fixing the reinforcing angle 37 to the blade 12 and providing the hood portion 38, the mechanical strength of the blade 12 can be greatly increased. The hood portion 38 prevents the potato P cutting juice and the like from being scattered around when the potato P is cut.

  Further, on the back side of the washer 30 near the cutting edge 34 of the cutting blade 32, an arc portion 30b is formed as shown in FIG. The arcuate portion 30b is formed with an inclined surface portion 30c so as to incline toward the cutting blade 32, and the inclined surface portion 30c extends substantially parallel to the cutting edge 34 of the cutting blade 32.

  On the other hand, as shown in FIGS. 9 and 10, the support base 11 has an opening 40 formed in the vicinity of the bottom of the blade 12. That is, the opening 40 is formed in a rectangular shape on the support base 11 below the cutting blade 32. A drawer portion 41 is disposed directly below the opening 40 as shown in FIG. The drawer portion 41 is configured to be detachable from the horizontal direction with respect to the support rail 42 fixed to the support base 11.

  Therefore, the cutting juice generated when the potato P is spirally cut by the cutting blade 32 is accumulated in the drawer 41 from the blade 12 through the opening 40. When a certain amount of cut soup accumulates, the drawer 41 is pulled out from the support rail 42 of the support base 11 in the horizontal direction to discard the cut soup, and the drawer 41 is mounted on the support rail 42 again. Thereby, the support base 11 can always be kept clean without being contaminated with the cutting juice.

  Furthermore, a rod-shaped body cover 43 that can surround the tip of the rod-shaped body 33 is attached to one end of the support base 11 as shown in FIGS. The entire rod-shaped body cover 43 is formed in an approximately L shape, and a long hole 43a is formed at the center of one side. The rod-like body cover 43 is fixed by inserting the screw portion of the thumbscrew 44 through the elongated hole 43 a and screwing this screw portion into one end of the support base 11. Further, a bent portion 43b that bends is formed on the other side of the rod-shaped body cover 43.

  Therefore, when transporting the food spiral cutting device 10 of the present embodiment, the thumbscrew 44 is loosened and rotated so that the rod-shaped body cover 43 is in the vertical direction, and the bent portion 43b of the rod-shaped body cover 43 is the rod-shaped body 33. After extending vertically upward so as to be higher, by tightening the thumbscrew 44, the rod-shaped body cover 43 is positioned so as to surround the tip of the rod-shaped body 33 as shown in FIG. Thereby, at the time of transportation of the food spiral cutting device 10 of the present embodiment, it is possible to prevent a problem that the rod-shaped body 33 is unexpectedly brought into contact with the tip of the rod-shaped body 33 and bent. When the food spiral cutting device 10 is used, the thumbscrew 44 is loosened and rotated so that the rod-shaped body cover 43 is in the horizontal direction, and the bent portion 43b is formed on the support base 11 as shown in FIGS. The thumbscrew 44 is tightened by positioning so as to contact the front side.

  Further, in the food spiral cutting device 10 of the present embodiment, the support plate 16, the guide portion 18, the operation knob 22 and the handle 24 are formed of synthetic resin, but the other members are all formed of stainless steel. ing.

  Next, the spiral cutting operation by the food spiral cutting apparatus 10 of this embodiment is demonstrated. 13 is a perspective view showing a use state of the food spiral cutting device of FIG. 9, and FIG. 14 is a perspective view showing the use state of the food spiral cutting device of FIG. 9 as seen from another direction.

  When the food spiral cutting device 10 is used, the thumbscrew 44 is loosened and rotated so that the rod-shaped body cover 43 is in the horizontal direction as described above, and the bent portion 43b is a support base as shown in FIGS. 11 so as to be in contact with the front surface side of the head 11 and tighten the wing screw 44 so that the rod-shaped body cover 43 does not interfere with the cutting operation.

  Then, during the cutting operation, the operation knob 22 is operated, and as shown by a two-dot chain line in FIG. 5, the rotation arm 19 is rotated about the rotation shaft 19a to rotate the screwing member 21 forward and upward. The joint member 21 is separated from the screw rod 23, and the screw rod 23 is separated from the support protrusion 31 side to the interval matching the length of the potato P as the object to be cut. , 18a, and at that position, the potato P is sandwiched between the support protrusion 31 and the locking protrusion 26 of the holding plate 25.

  Next, when the operation knob 22 is operated again and the screwing member 21 is turned downward about the rotation shaft 19a as shown by the solid line in FIG. 5, the screwing portions 21a and 21a are rotated. Is self-weighted and bites into the valley between the thread of the screw rod 23 and is screwed, and the weight of the operation knob 22, the rotating arm 19 and the screwing member 21 is loaded on the screw rod 23. It becomes a state.

  When the handle 24 is turned from this state, the screw rod 23 advances in a direction approaching the blade 12 according to the pitch. Then, when the screw rod 23 approaches the blade board 12 and is pressed against the cutting blade 32 of the blade board 12 while rotating the potato P by the locking projection 26 of the holding plate 25, the cutting blade 32 is shown in FIG. As shown in FIG. 14, the potato P is cut in a spiral shape along the axial direction while leaving the central portion from the outer peripheral direction toward the center, and is cut in a cross-sectional sinusoidal shape in the radial direction. Then, the potato P cut into a spiral shape and a cross-sectional sine wave shape is partially sent out from the opening 36 gradually and entangled with the rod-shaped body 33 in order, and is supported by the rod-shaped body 33 as a single body. The Rukoto. In addition, a small hole is formed in the center portion of the potato P cut into a spiral shape and a sinusoidal cross section by the support protrusion 31. The potato P thus spirally cut is fried and eaten with, for example, cooking oil.

  Here, since the circular arc part 12a and the slope part 12b are formed in the site | part in which the cutting blade 32 in the back side of the tool board 12 was installed, the level | step-difference part is lose | eliminated. As a result, the potato P that has been spirally cut is sent out along the circular arc portion 12a and the slope portion 12b, so that it can be sent out smoothly. Further, cutting juice generated when the potato P is cut in a spiral and sine wave shape by the cutting blade 32 is accumulated in the drawer 41 through the opening 40 from the front side of the blade 12.

  Note that when the potato P spiral cutting operation is completed and the locking projection 26 of the holding plate 25 approaches the cutting blade 32, the sliding surface portion 23a of the screw rod 23 faces the screwing portion 23a of the screwing member 21. Thus, even if the handle 24 is rotated, it only rotates idly and the locking projection 26 of the holding plate 25 does not approach the cutting blade 32 side.

  In addition, when trouble occurs during the work or when the end state is shifted to the next spiral cutting work, the operation knob 22 is operated, and the turning arm 19 is turned as shown by a two-dot chain line in FIG. When the screwing member 21 is rotated upward and forward about the shaft 19a so that the screwing member 21 is separated from the screw rod 23, the screw rod 23 is simply slid into the shaft holes 18a and 18a of the guide portion 18. Can move.

  Further, when replacing with another screw rod advancing / retracting mechanism 13 to which a screw rod 23 having a different screw pitch is attached, the nuts 29 and 29 with knobs in the existing screw rod advancing / retreating mechanism 13 are loosened and removed, and then the cover is removed. The frame 14 is pulled upward to disengage the insertion holes 28b, 28b formed in the extension 28a of the seat plate 28 from the bolts 27, 27.

  Next, after inserting the insertion holes 28b and 28b formed in the extension part 28a of the seat plate 28 in the other screw rod advancing / retreating mechanism 13 into the bolts 27 and 27 installed in the support base 11, the bolts 27 and 27 are knobs. By tightening the attached nuts 29, 29, it is possible to replace the other screw rod advance / retreat mechanism 13.

  As described above, according to the present embodiment, since the screw rod advance / retreat mechanism 13 is configured to be detachable from the support base 11, it can be easily compared with other screw rod advance / retreat mechanisms 13 to which the screw rods 23 having different screw pitches are attached. It is possible to exchange it. Further, the potato P is held between the support projection 31 of the cutter board 12 and the holding plate 25, the handle 24 is rotated to rotate the holding plate 25, and the screw is fed close to the cutter board 12 to cut the cutting blade. By cutting the potato P in a spiral shape and a sine wave shape in section 32 and supporting the potato P cut in a spiral shape and a sine wave shape in cross section with the rod-shaped body 33, the usability is greatly improved and the potato P is also easy. And can be cut into spiral and cross-sectional sinusoidal shapes.

  Moreover, according to this embodiment, since the potato P is only held between the support projection 31 of the blade 12 and the holding plate 25, the potato P can be easily attached. Furthermore, since the potato P is spirally cut by rotating the holding plate 25 and screw-feeding it, it becomes possible to make the thickness of the potato P that is helically cut and cut into a sinusoidal cross section uniform. Since the potato P cut into a spiral cut and a cross-sectional sine wave is supported by the rod-shaped body 33, the potato P cut into a spiral cut and a cross-sectional sine wave is always separated without being interrupted. Since the shape as a thing can be maintained, it becomes possible to raise commercial value.

  Furthermore, according to the present embodiment, since the rod-shaped body cover 43 that can surround the rod-shaped body 33 is attached to the support base 11, the rod-shaped body 33 is surrounded by the rod-shaped body cover 43 at the time of transportation. It is possible to prevent a problem that the rod-shaped body 33 is bent unexpectedly by contacting the tip. In this embodiment, the tip of the rod-shaped body 33 is surrounded by the rod-shaped body cover 43. However, the present invention is not limited to this, and the entire rod-shaped body 33 is used by using a rod-shaped body cover having a size that surrounds the entire rod-shaped body 33. May be surrounded.

  And according to the present embodiment, the opening 40 is formed in the vicinity of the attachment portion of the blade 12 of the support base 11, and the drawer portion 41 that is detachable from the horizontal direction is disposed below the opening 40. Cutting juice generated when the potato P is cut using the cutting blade 32 of the blade 12 is accumulated in the drawer from the blade 12 through the opening 40. Thereby, the support base 11 can always be kept clean without being contaminated with the cutting juice.

  Further, according to the present embodiment, the potato P that has been spirally cut has a small hole formed by the support protrusion 31 at the center thereof, and a stick such as a bamboo skewer or a resin skewer is inserted into the hole and stored. By doing so, it is possible to always maintain the shape as a continuous integral body. Here, the shape of the potato P spirally cut is unstable because the potato P is cut in a spiral shape along the axial direction while leaving the central portion from the outer peripheral direction toward the center. Therefore, by sticking and storing sticks such as bamboo skewers and resin skewers as described above, it is possible to always maintain the shape as a continuous unit even if vibration is applied by transfer and conveyance.

  Various modifications can be made to the above embodiment. For example, in the above embodiment, the support protrusion 31 and the long rod-shaped body 33 are integrally formed and fixed to the mounting hole 30a by welding, but in addition to this, the support protrusion 31 and a part of the rod-shaped body 33 are externally threaded. On the other hand, a female screw may be formed in the mounting hole 30a so that both are screwed together.

  Thus, by forming the support protrusion 31 and the long rod-shaped body 33 integrally and detachably attaching them to the mounting hole 30a, the rod-shaped body 33 according to the length of the object to be cut and the number to be supported. It is possible to exchange for a different length. Specifically, in the above embodiment, the rod-shaped body 33 supports one potato P that is cut in a spiral shape and a sinusoidal cross section. However, if the rod-shaped body 33 is formed to be longer, a plurality of potatoes P are supported. It becomes possible to support the potato P that has been spirally cut.

  Moreover, in the said embodiment, although the cutting blade 32 was fixed to the blade board 12 with the washer 30 so that the blade edge | tip 32a might contact the support protrusion 31, not only this but the cutting blade 32 is set with respect to the support protrusion 31, for example. The cutting blade 32 may be configured to be movable so as to come into contact with and away from it, and the cutting blade 32 may be moved so that the blade tip 32a contacts the support protrusion 31 only during a cutting operation.

  Furthermore, in the said embodiment, although the attachment hole 30a was formed in the washer 30, you may make it form the attachment hole 30a directly in the blade board 12. FIG. Thereby, the number of parts can be reduced. In addition, the attachment hole 30a may be formed directly in the cutting blade 32. In this case, it is necessary to arrange so that the outer periphery of the support protrusion 31 is in contact with the cutting edge 32a of the cutting blade 32 as described above.
