The above-described comb blade configuration in which a large number of blades are arranged side by side at a constant pitch is not only troublesome to manufacture but also involves the risk of cutting fingers.
The problem to be solved by the present invention is to provide a comb blade assembling jig for a tab cutter that wipes out the above-mentioned conventional drawbacks.

  In order to solve the above-mentioned problems, the invention described in claim 1 is characterized in that a plurality of inner upper guide grooves ending from an opening on one end side to a terminal end before the end surface facing the opening, and each inner upper guide A parallelogram blade is formed in the case of a flat box-shaped comb blade that forms a large number of inner lower guide grooves that are connected to the insertion holes of the end face from the opening portion so as to face the groove. A comb blade assembling jig for a hook cutter that abuts against a terminal portion and protrudes the blade tip from the insertion hole, a set portion that can hold the case for the comb blade firmly, and A guide groove drilling portion that can be correctly connected to the inner lower guide groove of the set case, and the depth of the guide groove drilling portion is such that the blade fitted in the groove can stand on its own. It is characterized by .

  The jig for assembling the comb cutter of the present invention is self-supporting if a large number of blades are inserted into the grooves at the guide groove drilling locations, and after being self-supported in this way, the blades can be pushed all at once. Since the blade can be smoothly inserted into the case, it is effective in improving workability, and efficient work can be performed.

  First, the outline | summary of the tab cutter used for this invention is demonstrated with FIG. 1 (A) and (B). The base 1 is composed of a first member 1a and a second member 1b. The first member 1a is an elongated rack 2 in which teeth 2a are continuously formed on one side surface of the end portion 5 on the side end surface. And two guide bars 3 and 4 arranged on both sides of the rack 2 are formed. The second member 1b forms a fixed wall 6 at the top.

  In order to assemble the base 1, the movable casing 20 is slidably fitted into the guide bars 3 and 4 of the first member 1a, and then the rack 2 and the guide bars 3 and 4 of the first member 1a are inserted. The second member 1b is fitted on the free end side so that the movable casing 20 does not fall off the base 1.

  A large opening 6 'is formed in the fixed wall 6 of the second member 1b (see FIG. 2), and the tool post 12 attached to the opening 6' is shown in FIGS. 3 (A) and 3 (B). As described above, the side plates 15 and 15 having the engaging projections 14 that can be fitted into the openings 6 ′ are opposed to each other, and the overhanging portions 16 and 16 formed integrally with the side plates 15 and 15 are formed as gaps 17 and 17. The engaging projections 14 of the tool rest 12 are opened to the opening 6 ′ by fitting the side plates 15 and 15 of the tool rest 12 into the opening 6 ′ of the fixed wall 6. The turret 12 can be removed by displacing the projections 14 and 14 for pushing and engaging inward with the protruding portions 16 and 16 facing inward. Reference numeral 19 denotes a mounting bolt for the comb blade 10.

  The center pipe 8 attached to the center pipe attachment portion 8a shown in FIG. 1B protrudes from a concave portion 13 formed in the tool post 12. As shown in FIG. 1 (A) and FIG. 11, the tip of the center pipe 8 has a notch circle shape. Therefore, when attaching the flat blade 11, the cutting edge is spaced from the notch circle tip of the center pipe 8 at an appropriate distance. Therefore, the flat blade 11 can be easily and easily attached, and there is little possibility of the blade edge of the flat blade 11 hitting the center pipe 8 when the tool post 12 is attached or removed.

  Since the conventional center pipe 8 has a perfect circle shape including the tip as shown by a two-dot chain line in FIG. 11, the corner of the flat blade 11 'is made to coincide with the intersection a between the outer shape of the center pipe 8 and the center line. Therefore, there is a great risk that the edge of the flat blade 11 ′ will hit the center pipe 8 when the attachment is removed.

  The tool post 12 is formed with a product delivery opening 9 extending in the radial direction from the vicinity of the concave portion 13, and skewer blades 10 and flat blades 11 are disposed on both side edges of the opening 9 to cut the hook. The blade portion 7 is configured (see FIG. 2).

  The radish, which is the workpiece, has one end surface pierced into the projecting piece 21 of the holder 22 and the other end surface pierced into the center pipe 8, and the radish thus held is rotated by turning the handle 23 as will be described later. Since the feed is applied to the movable casing 20, the end face of the rotating radish is pressed against the hook cutting portion 7 to cut the hook.

  In general, since the cross section of a sashimi knob is approximately 1 mm square, it is desirable to feed approximately 1 mm by one rotation of the handle 23. Therefore, in the fixed amount feeding means 30 shown in FIG. 4, a rotary shaft 32 having a holder 22 at the front end and a handwheel handle 23 at the rear end is rotatably provided on the movable casing 20, and a gear box 33 is provided on the rotary shaft 32. The gear box 33 is provided with a worm 31 fixed to the rotary shaft 32 and a worm wheel 34 that meshes with the worm 31, and the worm wheel shaft 35 is rotatably supported by the gear box 33. The pinion 36 is attached to the shaft end so as to be able to mesh with the teeth 2a of the rack 2 described above.

  For the convenience of illustration, only the lower portion of the gear box 33 is shown, but the upper portion is actually attached in an overlapping manner (see FIG. 5). The module of the gear train comprising the worm 31, the worm wheel 34, the pinion 36 and the teeth 2a of the rack 2 is 1, the number of teeth of the worm wheel 34 meshing with the worm 31 is 36T, and the number of teeth of the pinion 36 meshing with the rack 3 is 12T. When the handwheel 23 and thus the worm 31 are rotated once, the worm wheel 34 is rotated by 10 ° and the pinion 36 is also rotated by the same angle. Therefore, the moving length of the movable casing 20 is π due to the engagement of the pinion 36 and the rack 2. / 3, that is, a feed of about 1 mm can be achieved.

  A fixed amount of feed is achieved by meshing the teeth 2a of the rack 2 and the pinion 36. Further, by releasing the meshing, it is possible to move forward and backward by hand pushing, but the switching means 40 is shown by a one-dot chain line in FIG. Thus, a switching operation plate 41 having a small hole 42 through which the worm wheel shaft 35 penetrates is provided. On the other hand, as shown in FIGS. Is provided with a horizontal guide groove 24, and the switching operation plate 41 is slidably inserted into the horizontal guide groove 24, and the switching operation plate 41 is moved along the horizontal guide groove 24 by an external force. Is made by

  In the example of FIG. 5, the knob 45 that is elastically pressed upward by the interior spring 44 is provided in the movable casing 20, but an inclined tip portion 47 is formed on the operating rod 46 attached to the knob 45, and the inclined tip is provided. When the portion 47 is inserted into the engagement hole 43 formed in the switching operation plate 41 and the operation rod 46 is lifted by the internal spring 44 as shown in FIG. 5A, the switching operation plate 41 is operated. The worm wheel shaft 35, which is pushed by the inclined tip portion 47 of the flange 46 and penetrates the small hole 42 of the switching operation plate 41, is separated from the rack 2, and the engagement between the pinion 36 and the teeth 2 a of the rack 2 is released.

  However, as indicated by the arrow in FIG. 5B, when the knob 45 is pushed down against the internal spring 44 and the operation rod 46 is lowered, the switching operation plate 41 engaged with the inclined tip portion 47 is moved to the teeth 2a of the rack 2. The worm wheel shaft 35 is rotated about the horizontal shaft 32, and the pinion 36 and the teeth 2a of the rack 2 are engaged.

  In a different example of the switching means 40 in FIGS. 6A and 6B, a switching operation plate is formed by drilling an opening 25 in the movable casing 20 where the above-described horizontal guide groove 24 is connected to the outside and revealing from the opening 25. The portion 41 can be directly pushed by hand in the direction of the arrow or pushed from the opposite side, but it may be of such a simple structure.

  Next, the comb blade 10 will be described. As shown in FIGS. 7A and 7B, the upper inner surface and lower inner surface of the case 50, which has a flat box shape with one end side as an opening, have, for example, a large number of upper guide grooves 51 at a pitch of 1 mm. A lower guide groove 52 is formed to face each other, and an insertion hole 53 connected to the lower guide groove 52 is formed in the end surface 54 opposite to the opening.

  As shown in FIG. 7C, the upper guide groove 51 ends before the end surface 54 of the case 50, and forms a terminal step portion 55. When the blade 58 having the communication hole 59 as shown by the alternate long and short dash line is inserted between the upper and lower guide grooves 51, 52 from the opening side of the case 50, it contacts the end point 55 of the upper guide groove 51. After contact, it cannot be inserted any more, but at that time, the tip of the blade 58 protrudes from the insertion hole 53 of the case 50 for a certain length.

  When the blades 58 are inserted, next, as shown in FIG. 9, hot melt or molten resin 56 is poured from the opening of the case 50 and the gaps between the blades 58 are filled through the communication holes 59 of the blades 58. To do. Finally, the back cover 57 is pressed against the case opening and solidified and integrated, thus completing the blade 10. FIGS. 10A, 10B, and 10C are perspective views of the comb blade 10 with the blade pitches set to 1 mm, 2 mm, and 3 mm. If the arrangement pitch of the blades is appropriately changed without making it constant, a handle close to hand cutting is obtained.

FIG. 8 shows a jig 60 that is convenient for efficiently inserting the blade 58 between the upper guide groove 51 and the lower guide groove 52 of the case 50 described above, which is an embodiment of the present invention.
The jig 60 includes a set portion 61 where the case 50 can be firmly set, and a guide groove drilling portion 62 which can be properly connected to the lower guide groove 52 of the case 50 set in the set portion 61.
