In general, various disposable chopstick manufacturing apparatuses have been proposed as manufacturing apparatuses for chopsticks (see, for example, Patent Documents 1 and 2).
JP-A-2-20304 (page 1-5, FIGS. 1 to 9) JP-A-6-114807 (page 1-5, FIGS. 1-16)

  However, since the above manufacturing apparatus manufactures split chopsticks with a constant thickness by forming split grooves and chamfering on the split chopstick material, it is not possible to manufacture two chopsticks that are not split chopsticks. Even if the manufacturing apparatus for two chopsticks is configured by applying the above manufacturing apparatus, it becomes a complicated and expensive apparatus using a rotary cutter or a feeding device.

  In addition, the above-mentioned conventional device is used as a device / apparatus where children and general amateurs can experience making chopsticks by hand at accommodations such as forest schools and hotels in locations close to wood production areas such as firewood. With such a power automatic processing device, the experience of processing wood manually is not possible at all.

  This invention was made in view of the above points, and square chopsticks with a square cross section, which is a two chopsticks, can be manufactured reliably and easily even by children and ordinary amateurs, and the experience of shaving wood by hand is provided. After that, the object is to provide a handmade chopsticks manufacturing tool that can obtain handmade chopsticks with a natural feel.

  In order to achieve the above object, a handmade chopstick manufacturing tool according to claim 1 is provided with a flat plate provided with a pressing member for pressing a work material by elastic force at a position in the vicinity of a blade edge on the lower surface of the table, and a longitudinal direction. A first fitting groove having a bottom surface in which a rectangular bar-shaped chopstick material cut into a fixed length projects upward and is inclined slightly forward and downward is provided on the upper surface extending to the left and right sides of the upper surface. And a first shaving table provided with a guide surface for guiding the left and right corners on the lower surface side of the flat plate, and two side surfaces adjacent to the upper surface portion extending in the front-rear direction in the first shaving table portion. The bottom surface of the chopped material that has been machined is protruded from the unprocessed side upward and is accommodated with second fitting grooves that are inclined slightly downwardly downward. A second cutting surface provided with a guide surface for guiding the left and right corners on the lower surface side of the base. A chamfering with the edge of the blade facing the top corner of the V-groove formed by the base and the orthogonal inclined surface, and a guide fitted to the V-shaped groove of the chamfer Inserted into the top ridge line portion of the holding table having a cross-sectional mountain shape with a face, the chopsticks material, which has been machined on the unprocessed side surface in the second shaving table unit, with the corners on the two adjacent sides facing upward And a chamfering table provided with a third fitting groove having a V-shaped cross section.

  In the present invention, the “front” side refers to the front side as viewed from the worker who performs the cutting process using the scissors, and the “rear” side refers to the opposite side (the front side of the worker). “Left and right” refers to the left and right direction relative to the front and rear direction from the rear side toward the front side.

  According to the first aspect of the present invention, the rectangular bar-shaped chopstick material is inserted into the first insertion groove of the first shaving table, and the two adjacent side surfaces of the chopstick material are sequentially shaved with a flat plate, If the other two side surfaces are sequentially cut with a flat blade after being inserted into the second insertion groove of the No. 2 shaving table, a semi-finished product (side processed product) with a tapered square chopsticks with a square cross section is obtained. Chamfered chamfered chamfered products can be obtained by chamfering the four corners with a chamfering rod by inserting it into the third insertion groove of the chamfering stand. In response, chamfer the four sides of the top of the chopsticks with a paper file to obtain a square chopstick product that is a finished product of handmade chopsticks.

  The side cutting with the flat plate of the chopsticks is only necessary to move the flat plate back and forth (reciprocate back and forth) a plurality of times along the flat surface portion of the first and second cutting tables. Therefore, the work is easy, and the flat bed is guided by the guide surface of each shaving table and moves back and forth in a stable state, and the chopsticks have their side surfaces protruding from the insertion grooves in the front-rear direction of each insertion groove. The taper is cut off with a thickness corresponding to the inclination, and a tapered chopstick with a predetermined dimension can be obtained with certainty. In addition, even when chamfering is performed by the chamfering described above, the chamfering is only required to be moved back and forth multiple times by fitting the V-shaped groove to the guide surface of the holding stand, and the work is easy. The scissors are guided by the guide surface of the holding table and can be moved back and forth without tilting to the left or right to form chamfered portions with a predetermined chamfer width at the four corners of a semi-finished product of chopsticks (side processed product). It is.

  In the present invention, the first shaving table, the second shaving table, and the chamfering table may be independent from each other, or the first shaving table and the second shaving table may be integrated. According to a second aspect of the present invention, the first shaving table, the second shaving table, and the chamfering table are fixedly mounted on a single substrate in a state where their longitudinal directions are arranged in parallel. If this is the case, the first shaving table, the second shaving table, and the chamfering table are integrated with a large substrate on the left and right sides, and the overall weight becomes large. At the time of chamfering by the method, rattling and falling of each shaving table and chamfering table are prevented, and work can be performed in a stable state, which is preferable.

  Further, in the present invention, when the chopstick material after side cutting on the first shaving table and the second shaving table is taken out from each fitting groove, one longitudinal end portion of the chopstick material fitted into each fitting groove The other end protruding upward by reaction and pressing with a finger or the like may be taken out by gripping with another finger, but as in the invention according to claim 3, A chopstick material push-up device comprising a push-up member that can freely protrude into the first fitting groove and a push-up drive mechanism that drives the push-up member upward by manual operation is provided. Driven upward by manual operation if the chopstick material push-up device comprises a push-up member that can protrude into the second fitting groove and a push-up drive mechanism that drives the push-up member upward by manual operation. The chopsticks are pushed up by the lifted member so that the chopsticks can be It can be removed from the fitting groove and gripped by the fingers.

  Further, in the invention described in claim 3, the chopstick material lifting device may be provided separately for the first shaving table and the second shaving table. However, as in the invention described in claim 4, the first and second devices If the scraper is integrally formed with the longitudinal direction parallel to each other, and the push-up members of both scrapers are driven upward by a common push-up drive mechanism, the common lift drive mechanism This simplifies the configuration of the chopstick material push-up device and unifies the push-up operation, making it easier to work.

  In the present invention, a chamfering rod dedicated to chamfering may be used separately from the flat plate, but as in the invention according to claim 5, a pair of bar members each having an inclined surface portion on one side, A guide tool in which the inclined surface portions are opposed to each other and are connected to each other with a predetermined interval between the tip edge portions to form a V-shaped groove between the both inclined surface portions, and the upper surfaces of the both bar members are flattened. A chamfer dedicated to chamfering is constructed by detachably attaching to the base in a state of being superimposed on the bottom surface of the base of the coffin and using the flat plate with the guide attached as the chamfering base. It eliminates the need for a scissors blade and a support base that supports it, and can be used for chamfering at low cost. Also, it is easy to maintain and sharpen a scissors blade for a single scissors. The storage space in the chamfering area is just one chamfer and does not take up much space.

  In the present invention, the top surface portion of the chopsticks after chamfering may be chamfered with a paper file or the like held on the fingertip portion. However, as in the invention according to claim 6, at least the upper surface side of the plate piece is made of paper. If the filed plate is formed by attaching a file as a chamfering tool for the top surface of the chopstick material after chamfering in the chamfering table, the filed plate is placed on a workbench or the like. The top surface portion can be easily chamfered by holding it at the top or attaching it to the substrate of claim 2 and rubbing the top surface of the chopsticks material against the top surface at an angle. A chamfered portion having a good appearance with little unevenness in width can be formed.

  According to the present invention, the shaving processing of the chopsticks material fitted into the fitting grooves of the first and second shaving bases by the flat surface and the chamfering of the chopsticks material fitted into the fitting grooves of the chamfering table. By the chamfering process, a tapered square chopstick with a predetermined shape can be obtained. The shaving process using the flat plate can be performed by moving the flat plate back and forth along the plane portions of the first and second cutting tables. Since the chamfering process with the scissors only needs to move the chamfering tool back and forth along the guide surface of the chamfering table, both work are easy. Even ordinary amateurs can manufacture it reliably and easily, and through hand-crafted wood shaving experience, you can get handmade chopsticks with a natural feel.

  In addition to the above effects, according to the invention described in claim 2, rattling and falling of each shaving table and chamfering table can be prevented at the time of shaving with a flat surface and when chamfering with a chamfering surface. Work in a stable state.

  In addition to the above effects, according to the invention described in claim 3, the chopstick material is pushed up by a push-up member driven upward by manual operation, and the chopstick material is securely and easily gripped by fingers. Can be removed from the groove.

  In addition to the above effect, according to the invention described in claim 4, the structure of the chopstick material lifting device is simplified due to the common use of the lifting drive mechanism, and the lifting operation is unified so that the work can be easily performed.

  In addition to the above effects, according to the invention described in claim 5, chamfering can be obtained at low cost, and it is easy to maintain the sharpening of the scissors blade, and storage space when not in use is also taken up. Absent.

  In addition to the above effects, according to the invention described in claim 6, the top surface portion of the chopstick material can be easily chamfered, and a chamfered portion having a good appearance can be formed.

It is selected according to the chamfer width, and this point will be described later.

  The chamfering table 4, the first shaving table 2, and the second shaving table 3 integrated with the chamfering table 4 are fixedly mounted on a wooden substrate 6 in a state where the longitudinal directions are arranged in parallel.

  Reference numeral 40 denotes a chopstick material push-up device provided on the first shaving table 2 and the second shaving table 3, and the bottoms of the first fitting grooves 12, 12 and the second fitting grooves 22, 22 are provided. The four pin-like push-up members 41 fitted in the through-holes so as to be movable up and down are driven upward by manual operation by a push-up drive mechanism 42 common to both of the shaving bases.

  The push-up drive mechanism 42 fixes the bases of the four drive pins 44 that engage with the lower ends of the push-up members 41 to the drive shaft 43 that is rotatably supported by penetrating both shaving bases in the left-right direction. A wooden lever 45 for operation is fixed to the end of the drive shaft 43 protruding to the side of the second shaving table 3. Reference numeral 46 denotes a retaining pin fixed to the lower part of each push-up member 41. As a space for accommodating the pin 46 and the drive pin 44, each shaving base has four grooves 47 that open downward. It has been cut.

  2 and 3, the file base 5 is formed by covering a rectangular plate-like piece of wood 5 a with a paper file 5 b except for a part of the front and rear end surfaces and the bottom surface, and connecting the two with pegs. In this example, this is fixedly mounted on the substrate 6 by screwing at a side position of the second shaving table 3.

  On the other hand, as shown in FIGS. 8 to 13, the flat rod 7 is formed on the mounting plate 53 attached to the inclined surface on the top side of the substantially V-shaped upper hole 52 formed on the upper surface 51 a side of the rod base 51. Is fastened with a screw 55, and a back plate 56 is fastened with a screw 57, and 58 is screwed into a support wall 59 fixed to the mounting plate 53, and the front end abuts against the rear end surface of the back plate 56 It is the made back metal position adjustment screw. Reference numeral 61 denotes a wooden handle attached to the upper surface 51a of the base 51d on the top 51d side, and 62 denotes a protrusion projecting from the end surface of the base 51e of the base 51. A small-diameter steel ball protrudes partly from the base 51 It is made by bonding and fixing to.

  As shown in FIGS. 10 to 11, the left and right edges on both sides of the blade edge 60 on the lower surface 51 b of the rod base 51 are stepped surfaces 51 c that protrude a little from the opening surface portion of the blade edge 60. The amount of cutting edge is adjusted so that the cutting edge 54a of 54 comes to a position between the stepped surface 51c and the opening surface portion of the blade edge 60. In addition, in FIG. 10, illustration of the below-mentioned pressing member 65 is abbreviate | omitted.

  In FIGS. 11 to 13, reference numeral 65 denotes a pressing member made of an elastic material (in this example, a stainless steel thin plate), which is screwed into a fitting hole 66 provided in the vicinity of the blade edge 60, and has an intermediate curved portion 65 a. Are protruded from the lower surface 51 b, and the two pressing members 65, 65 are fitted into the two fitting grooves 12, 22 of the first shaving base 2 and the second shaving base 3, respectively. It is provided in the left and right positions where the work material can be pressed.

  Next, as shown in FIGS. 14 to 15, the guide 8 includes a pair of rods 71 and 71 having a substantially horizontal trapezoidal cross section with an inclined surface portion 71 a on one side, and the inclined surface portions 71 a and 71 a. It is made to oppose and it arrange | positions with the predetermined | prescribed small space | interval T between the front-end | tip edge parts, screwing connection metal fittings 72 and 73 to the both ends, and connecting integrally, between the orthogonal inclined surface parts 71a and 71a V-shaped groove 74 is formed on the surface. A stepped portion 71c deeper than the projecting height of the stepped surface 51c portion, into which the stepped surface 51c portion of the lower surface of the base 51 of the flat rod 7 is fitted, is formed on the upper surface 71b of the both bars 71, 71 in the connected state. Thus, the cutting edge 54a of the scissors blade 54 comes to a position in the vicinity of the upper surface 71b of the bar 71 in an attached state to the flat scissors 7 described later.

  The connection fitting 72 is made of a metal plate, has a notch portion slightly larger than the V-shaped groove 74 in the lower portion, and has a fitting portion 75 that fits the top 51d portion of the base 51 of the flat rod 7 in the upper portion. The connection fitting 73 is also made of a metal plate, and has a cutout portion similar to the connection fitting 72 at the lower portion, and a round hole 76 into which the projection 62 provided on the base 51e of the base 51 of the flat rod 7 is fitted. It is drilled in.

  FIGS. 16 to 17 show a state in which the guide 8 is attached to the base 51 of the flat rod 7 to form a chamfered rod 78. The guide 8 first sets the fitting portion 75 of the connecting bracket 72 on the front end side to the base. After being hooked on the head 51d portion of 51, as shown in FIG. 16, the rear end side is rotated as shown by the arrow R toward the base 51e of the base 51 and connected to the protrusion 62 of the base 51e. If the round hole 76 of the metal fitting 73 is fitted, the upper surface 71b of the bar 71, 71 is brought into contact with the lower surface 51b of the base 51 after the round hole 76 is fitted to the projection 62 by the elastic force of both the coupling metal 72, 73. They are connected and held together in an overlapping state (via a small amount of clearance because of the separation force by the pressing member 65). The guide 8 may be removed from the flat rod 7 in the reverse procedure.

  In order to manufacture handmade chopsticks using each apparatus and instrument having the above-described configuration, the substrate 6 in which the first shaving table 2, the second shaving table 3, the chamfering table 4, and the file plate 5 are fixedly attached to the upper surface side. Is placed on a stable table such as a work table. Then, as shown in FIGS. 18 to 19, first, two rectangular bar-shaped chopsticks materials 80 cut into a standard material, which are raw materials, are prepared, and the numbers 1 to 4 consecutive on the four side surfaces of each chopstick material 80 are adjacent to each other. Write sequentially on the matching side with a pencil. Then, the two chopsticks 80 are inserted into the first insertion groove 12 of the first shaving table 2 with the first side surface with the numeral 1 facing upward. The protruding first side surface portion is shaved. The shaving work may be performed by moving the flat plate 7 holding the table 51 by hand back and forth a plurality of times along the guide surface 15 while pressing downward, whereby the chopstick material 90 is moved by the pressing member 65 to the first. While being pressed against the bottom surface 12 a of the fitting groove 12, the first side surface portion is cut by a taper cutting allowance 91 shown by hatching in FIG. 19B. In addition, FIG. 19 is a schematic diagram showing the chopsticks material in the longitudinal direction shortened, and the machining allowance and the tapered inclination of the processed product are exaggerated, and each end view is shown on each side. The entered numbers 1 to 4 are appended.

  This tapered cutting allowance 91 is the inclination of the bottom surface 12a of the first fitting groove 12 and the vertical position of the blade edge 54a of the blade shown in FIG. 20 (however, the state where the blade 51 is pressed against the upper surface 11 of the blade) These are selected according to the shape of the final product of chopsticks, and the same applies to the second shaving table 3. Further, as shown in FIG. 20, the formation of the stepped surface 51c on the lower surface of the gantry 51 causes the blade edge 54a of the ridge blade to be at a position slightly above the upper surface portion 11 of the shaving table. This also applies to the second shaving table 3. FIG. 20 shows a state in which a gap is opened vertically between the upper surface portion 11 of the shaving table and the base 51 (a state before pressing), and this point is the same as in FIG. 23 described later.

  After machining the first side, take out the two processed products from the first fitting groove 12, rotate 90 degrees around the axis, and turn the second side with the number 2 up. Then, after reinserting into the first insertion groove 12, the second side surface portion is similarly cut using the flat plate 7, and after removing the cutting allowance 92 minutes, the first insertion is performed as the primary processed product 81. Take out from the groove 12.

  When taking out the first side processed product and the second side processed product (primary processed product 81) from the first fitting groove 12, the lever 45 of the chopstick material push-up device 40 is lifted with one hand. If the turning operation is performed in the direction, the drive pin 44 drives the push-up member 41 upward by turning the drive shaft 43, and the first fitting groove is projected by the push-up member 41 protruding into the first fitting groove 12. Since the chopstick material in 12 (specifically, each processed product described above) is lifted upward, it can be easily taken out with the other hand. If the lever 45 is rotated to the original position after taking out, the push-up member 41 is lowered by its own weight, and the tip surface returns to the original state below the upper surface portion 11. The removal from the second shaving table 3 can also be performed by a similar operation.

  Next, the above-mentioned two primary processed products 81 are moved to the second shaving table 3 side, and are fitted into the second fitting groove 22 with the third side surface with the number 3 attached upward. After the third side surface portion is cut and the cutting allowance 93 shown in FIG. 19 (c) is cut off, the second side is taken out from the second fitting groove 22, and the second side surface with the numeral 4 is then placed on the second side. If the fourth side surface portion is cut again by the flat plate 7 and the cutting allowance 94 is cut and taken out from the second fitting groove 22, the taper shown in FIG. A square chopstick-shaped side processed product 82 is obtained.

  Therefore, as shown in FIG. 21, the side processed product 82 is fitted into the third fitting groove 33 of the chamfering table 4 with the corners 82 a on the two adjacent side faces facing upward, and the guide 8 is fitted to the flat plate 7. The corner portion 82a is chamfered by using the chamfering rod 78 obtained by the mounting, and then the third chamfering portion is taken out from the third fitting groove 33 and rotated by 90 degrees around the axial center. If the process of chamfering by reinserting into the fitting groove 33 is repeated, a chamfered product 83 having chamfered corners as shown in FIG. 19C is obtained.

  In the above chamfering process, the top of the chamfering table 4 is fitted into the V-shaped groove 74 of the guide tool 8 part of the chamfering bar 78, and the chamfering bar 78 which is gripped by the hand 51 part by hand can be moved back and forth several times. The chamfering rod 78 is guided by the guide surfaces 31 and 31 of the chamfering table and can be moved back and forth in a stable state without being greatly shaken. A chamfer 83a having a chamfer width is formed.

  This chamfer width is determined by the front / rear inclination of the third fitting groove 33 and the vertical position of the blade edge 54a of the scissors blade in FIG. 17, and these are selected according to the desired chamfer width. For example, in FIG. 21, the exposed two side surfaces 82b and 82b of the side processed product 82 fitted in the third fitting groove 33 are substantially the same as the guide surfaces 31 and 31 of the chamfering table 4 over the entire length of the groove. By setting the groove depth to be uniform, chamfering can be performed with a uniform chamfering width over the entire length of the chopstick material. The two side surfaces 82b and 82b may protrude from the guide surfaces 31 and 31 in a small amount. In this case, the V-shaped groove 74 of the chamfering rod 78 is directly guided by the two side surfaces 82b and 82b. Further, a range portion (a front portion and a rear portion of the third fitting groove 33) in which the third fitting groove 33 of the top ridge line portion 32 of the chamfering table 4 is not provided is a cutting edge 54 a of the scissors blade of the chamfering rod 78. So as not to interfere with each other, it may be appropriately chamfered in advance according to the position of the blade edge or the like.

  The chamfered product 83 obtained by the above chamfering process may be a finished product of handmade chopsticks as it is when the wood is soft, or the chamfered product 83 by hand when the wood is hard. By gripping in an inclined state and pressing the four sides of the top surface portion 83b against the upper surface of the file plate 5 in order and moving back and forth, the handmade chopsticks having an excellent appearance with a chamfered portion 83c on the top portion shown in FIG. A finished product 84 is obtained. Note that the chamfered portion 83c may have a rounded cross-sectional shape. When the file plate 5 is not fixed on the substrate 6, the chamfering of the top surface portion 83b is performed by the file plate 5 held by hand, or when the file plate 5 is not present, by a paper file held by hand. You may do.

  As described above, the shaving processing by the flat plate 7 on the side surface of the chopstick material (including processed products of chopstick material) inserted into the respective insertion grooves of the first shaving table 2 and the second shaving table 3, and the surface By chamfering the chopsticks material (specifically, the side processed product 82) fitted in the fitting groove of the take-up table 4 with the chamfering rod 78, a square chopstick product having a predetermined shape can be reliably obtained, and the above processing work is performed. Sometimes the flat plate 7 only needs to be moved back and forth along the upper and lower surface portions 11 and 21 of the first and second cutting tables, and the chamfering plate 78 is also moved back and forth along the guide surface 31 of the chamfered table 4. Therefore, both are easy to work, and children and general amateurs can easily make square chopsticks.

  The present invention is not limited to the above example. For example, the stepped surface 51c of the lower surface of the flat basket 51 in the above example is omitted, and the lower surface 51b of the rack 51 is planar as shown in FIG. And a stepped portion 17 (this upper surface functions as a guide surface 15) that protrudes a small amount upward is formed on the left and right edges of the upper surface portion 11 of the first shaving table 2, and the upper surface is formed by the blade edge 54a of the scissors blade. The part 11 may be prevented from being scraped. In this case, the second scraper 3 may be configured similarly.

  In the above example, since the first shaving table 2, the second shaving table 3, and the chamfering table 4 are fixedly mounted on one substrate 6, the overall weight and the lateral width are large, and the flat Although the work can be performed in a stable state during the chamfering process with the chamfer 7 and the chamfering process with the chamfering bar 78, each of the chamfering table 4 and the chamfering table 4 are separated from each other without using the substrate 6. Alternatively, as in the above example, the first shaving table 2 and the second shaving table 3 may be integrated (no substrate).

  Further, in the above example, the first insertion groove 12 and the second insertion groove 22 each contain one piece of chopstick material (including a processed product of chopstick material) in each upper surface portion 11, 21. Although each of the fitting grooves is arranged side by side, the fitting grooves may be wide enough to accommodate two chopsticks, and one wide fitting groove may be provided on each of the upper surface portions 11 and 21.

  In addition, as shown in FIG. 24, the chopstick material pushing-up device has a base end portion of an arm-like push-up member 48 whose front end portion can freely protrude into the fitting groove, and is fixed to the drive shaft 43.
