In this case, as shown in FIG. 3, the scallop A is conveyed with its ears C facing downward and the shell D facing upward (vertical), and the side surface of the ear C of the scallop A is the receiving surface 16 of the aligner 4 (FIG. 3). ), The intersection E between the ear C and shell D of the scallop A is raised substantially above the positioning portion 17 of the aligner 4, and the perforated portion H is in a certain (substantially constant) direction (position). ).

(Guide)
The guide tool 3 (FIGS. 2A, 2B, and 3) guides (sends) the scallops A that have been manually put into the receiving portion 8 of the longitudinally rotating belt 1 one by one to the alignment tool 4 side. ), And the scallop A put in the receiving portion 8 slides down along the downwardly inclined feeding portion 18 and automatically approaches the alignment tool 4 side.

  As shown in FIG. 2 (b), the guide 3 is composed of an L-shaped support plate 19 and a guide member 20 attached to the front surface thereof. The support plate 19 has a fixed plate portion 21 and a guide material mounting portion 22 formed in an L-shape, and the fixed plate portion 21 has a bolt (not shown) inserted into its stop hole 23 (round hole), and It is fixed to the side surface of the protrusion 11 of the vertical rotating belt 1 by a nut (not shown) screwed to the bolt, and the guide material mounting portion 22 is not fixed to the vertical rotating belt 1 and is free. Is superimposed on the longitudinally rotating belt 1.

  As shown in FIG. 2B, the guide member 20 includes a horizontal upper surface 24, a downward slope 18 continuing to the upper surface 24, a bottom plate 27 continuing to the downward slope 18, and a back plate 28. The back plate 28 is provided inside the upper surface 24, the down slope 18, the side surface 26, and the bottom plate 27. The back plate 28 is overlapped in front of the guide material mounting portion 22 of the support plate 19, and from the stop hole 29 (FIG. 2B) opened in the guide material mounting portion 22, the horizontally long hole 31 ( 2 (a)), a stopper (screw or bolt) 30 (FIG. 2 (a)) is inserted, and a guide member is attached with a nut 32 (FIG. 2 (a)) screwed into the stopper (bolt) 30. It is fixed to the part 22.

  When the nut 32 of FIG. 2A is loosened, the back plate 28 (FIG. 2B) is laterally slid in the longitudinal direction of the laterally long hole 31, and the guide 3 is moved closer to or away from the alignment tool 4. I can do it. By making it approach, the space | interval with the alignment tool 4 becomes narrow, the front opening (horizontal width) of the insertion port 14 of the receiving part 8 becomes narrow, and it comes to be suitable for throwing in the scallop A with the small shell D. By separating, the interval with the alignment tool 4 is widened, and the opening (width) of the insertion port 14 is widened, which makes it suitable for loading the scallop A having a large shell D (FIG. 3).

  By using the support plate 19 and the guide member 20 as the mounting structure, the protrusion 11 of the vertical rotating belt 1 reaches the outside (direction changing portion) of the vertical rotating drum 12 as the vertical rotating belt 1 rotates. As shown in FIG. 2A, the guide member mounting portion 22 of the support plate 19 protrudes outward from the longitudinal rotating belt 1, and the longitudinal rotating belt 1 rotates outside the longitudinal rotating drum 12. I can do it. When the rotation of the vertical rotating belt 1 proceeds and the protrusion 11 finishes turning outside the vertical rotating drum 12 (after passing through the direction changing portion), the guide material mounting portion 22 overlaps the vertical rotating belt 1. It is.

(Alignment tool)
As shown in FIG. 2 (c), the aligning tool 4 includes a positioning portion 17 having a gentle angle, and the ear C and shell D of the scallop A that is loaded into the receiving portion 8 of the longitudinal rotation belt 1 and conveyed. The crossing portion E (FIG. 3) is positioned on and substantially aligned with the positioning portion 17 so that the scallop A is automatically aligned in a fixed (substantially constant) direction.

  The alignment tool 4 fixes only the fixing plate portion 33 (FIG. 2C) to the protrusion 11 of the vertical rotation belt 1 and the receiving plate portion 34 that overlaps the outside of the vertical rotation belt 1 is attached to the vertical rotation belt 1. It is in a free state without being fixed. With this mounting structure, when the protrusion 11 of the vertical rotating belt 1 reaches the outside of the vertical rotating drum 12 (direction changing portion) as the vertical rotating belt 1 rotates (FIG. 2A). As shown in FIG. 2, the back support portion 34 protrudes to the outside of the vertical rotation belt 1, and the scallop A (FIG. 2A) after drilling in front of the receiving plate portion 34 is discharged from the back support portion 34. It is made to do. Thereafter, when the vertical rotating belt 1 further rotates and smoothly passes the outside of the vertical rotating drum 12 and the protrusion 11 finishes rotating outside the vertical rotating drum 12 (after passing through the direction changing portion), the back support is performed. The portion 34 is returned to the vertical rotating belt 1 side so as to overlap the vertical rotating belt 1.

  Two long holes (long grooves) 35 (FIG. 2C) are opened in the fixing plate portion 33 of the alignment tool 4, and the fixing plate portion 33 is moved up and down in the longitudinal direction of the long holes 35. The attachment position (height) of the vertical rotating belt 1 to the protrusion 11 can be adjusted. When the mounting position is increased, the position of the positioning portion 17 (FIG. 2 (a)) is increased, so that the position of the positioning portion 17 and the intersection E (FIG. 4) of the large scallop A can be easily aligned. Suitable for alignment, when the mounting position is lowered, the position of the positioning portion 17 is lowered, the position of the positioning portion 17 and the intersection E (FIG. 3) of the small scallop A is easily aligned, and the small scallop A is aligned. Suitable for

(Electric drill and holder)
In the electric drill 5, a drill (drill blade) 9 is attached to the tip of the drill motor M1 by a chuck or other coupling tool, and the drill blade 9 is rotated by the rotation of the drill motor M1. This rotation can make a hole in the scallop A. The holder 6 is provided to prevent the scallop A from being displaced when a hole is made in the scallop A with the electric drill 5. So that it can be held in an aligned orientation. The holder 6 is made of rubber or resin and has a shape, structure, and material that can be easily pressed against the shell D of the scallop A. The electric drill 5 and the holder 6 are attached to the drive mechanism 7 with a common support and are driven together by the drive mechanism 7. In this case, as shown in FIG. 7A, when the holder 6 is protruded further forward than the electric drill 5 and the electric drill 5 and the holder 6 are moved forward together by the drive mechanism 7, The holder 6 is surely pressed against the scallop A before the electric drill 5. The electric drill 5 and the holder 6 are disposed to face the longitudinally rotating belt 1 as shown in FIG. A spring S is disposed behind the holder 6 (FIGS. 6A, 6 </ b> B, and 7 </ b> A).

(Drive mechanism)
The drive mechanism 7 (FIG. 1) uses the rotational force of the drive motor M2 (drive source: FIG. 1) as a power source to rotate the vertical rotation belt 1 in the direction of the arrow X (FIG. 2 (a)), thereby generating a lateral rotation belt. 2 can be rotated in the direction of the arrow Y (FIG. 2A). Further, as shown in FIGS. 7B and 7C, the electric drill 5 and the holding tool 6 are moved forward in the vertical rotation belt 1 side, moved in the rotational direction of the vertical rotation belt 1 and moved vertically. It is configured to move backward (in FIG. 7 (d)) and move (return) to the original position before the advance as shown by the phantom line in FIG. 7. The lateral movement is synchronized with the rotational speed of the longitudinal rotating belt 1 so that holes can be continuously drilled by the electric drill 5 in the scallop A being conveyed.

  The drive mechanism 7 rotates the pulley P2 (FIG. 1) connected to the drive mechanism 7 with the timing belt T hung on the pulley P1 (FIG. 1) of the drive motor M2 by the rotation of the drive motor M2, and the pulley P2 The front gear (gear) G (FIG. 1) is rotated, the gear (not shown) of the rotating shaft of the vertical rotating drum 12 (FIG. 2) meshed with the gear G is rotated, and the vertical rotating belt 1 is rotated. Rotate.

  The drive mechanism 7 transmits the rotation of the pulley P2 to a gear (not shown) of the rotating shaft of the horizontal rotating drum 15 (FIG. 2) by a power transmission mechanism (for example, gear: not shown) to transmit the horizontal rotating drum 15 to the horizontal rotating drum 15. Rotate the sideways rotating belt 2 to rotate.

  The drive mechanism 7 transmits the rotation of the drive motor M2 to the electric drill 5 and the holder 6 by a power transmission mechanism (not shown), and moves them forward, laterally, retracted, and returned.

(Side wall)
As shown in FIGS. 1, 5, and 11 (a), the shell punching device is provided with a side wall 40 at a position opposite to the outer side of the vertical rotation belt 1 and above the horizontal rotation belt 2. The scallop A in the receiving portion 8 of the orientation rotating belt 1 can be prevented from falling outside the longitudinal orientation rotating belt 1. In the side wall 40, thin plates are arranged to face each other in the vertical direction. The side wall 40 is provided in the region L of FIG. 1 and is rotated in the vertical direction until the scallop A is discharged to the outside of the vertical rotating belt 1 after the drilling of the scallop A introduced into the receiving portion 8 is completed. It is possible to prevent the belt 1 from falling outside.

(Usage example of shell drilling device)
The case where a hole is made in the ear of a scallop using the shell punching device of the present invention will be described below.
(1) The shell drilling device of the present invention is installed in the work place. In this case, as shown in FIGS. 8 and 9, the upper end side of the vertical rotating belt 1 is inclined (backward inclined) toward the worker 50 side. The vertical rotation belt 1 has a perforated region that passes through the case of the drive mechanism 7 and continuously rotates, but the other portions are out of the case.
(2) The operator 50 holds the scallops A by hand as shown in FIG. 1 and puts them one by one vertically into the receiving portion 8 from the insertion port 14 of the rotating vertical rotating belt 1.
(3) The scallop A introduced into the receiving portion 8 slides down along the descending slope (feeding portion) 18 of the guide 3 (FIG. 2A), and the shell D of the scallop A is shown in FIG. As shown in FIGS. 6 (a) and 6 (b), the hinge B side is supported on the laterally rotating belt 2 as shown in FIGS.
(4) The scallop A is conveyed in the direction of the arrow X in FIG. 1 by the vertical rotation belt 1 and the horizontal rotation belt 2. At this time, since the rotation speed of the horizontal rotation belt 2 is slightly higher than the rotation speed of the vertical rotation belt 1 (about 10%: adjustable), the scallop A is conveyed while being maintained in the vertical direction. The side faces the receiving surface 16 of the aligning tool 4 (FIG. 3), the crossing portion E of the scallop A is positioned by the positioning portion 17 of the aligning tool, and the ears C of the scallop A are aligned in a certain direction.
(5) When the conveyance of the scallop A progresses, as shown in FIG. 7A, both the electric drill 5 and the holder 6 in front of the longitudinal rotating belt 1 move forward to the scallop A side, and FIG. In this manner, the holding tool 6 presses the scallop A against the vertical rotation belt 1 to hold the scallop A between the vertical rotation belt 1. At this time, the holding tool 6 is pushed to the scallop A side by the spring S (FIGS. 6A and 6B) and presses the scallop A securely.
(6) When the electric drill 5 and the holder 6 are further advanced by the drive mechanism 7, the electric drill 5 presses against the ear C of the scallop A and opens a hole in the ear C (FIG. 7 (c)). At this time, since the spring S is compressed, the holder 6 does not press the scallop A more than necessary and the scallop A is not damaged.
(7) While the scallop A is drilled with the electric drill 5 and the holder 6, the scallop A moves in the conveying direction of the scallop A in synchronization with the scallop A and continues to be pushed by the holder 6. While continuing to drill holes with the electric drill 5.
(8) After drilling is completed, the holder 6 and the electric drill 5 are both retracted from the scallop A side, and the holder 6 is released from the scallop A as shown in FIG. , Return to the original position before the advance and enter the next drilling.
(9) By repeating the operations (2) to (8), holes can be sequentially formed in the scallop A that is conveyed by the vertical rotation belt 1 and the horizontal rotation belt 2.
(10) The drilling time for one scallop A (the time shown in FIGS. 7 (a) to (d)) can be adjusted, and the longitudinally rotating belt 1 can be drilled at about 100 holes per minute. The rotational speed of the lateral rotation belt 2 can be set. This rotational speed is adjustable.
(11) The scallop A after being drilled continues to be conveyed by the vertical rotation belt 1 and the horizontal rotation belt 2, and when the vertical rotation belt 1 reaches the rotation direction changing portion (the outer periphery of the rotation drum), FIG. As described above, the back support portion 34 of the aligning tool 4 protrudes outward from the longitudinal rotation belt 1 and discharges the scallop A to the outside. 2A, the scallop A discharged from the back support portion 34 of the aligner 4 is supported by the lateral rotation belt 2 because the rotation direction of the lateral rotation belt 2 is changed before the longitudinal rotation drum 12 as shown in FIG. It disappears and falls (collected).

It can be arbitrarily set so that the perforated portion H of the scallop A hits the alignment tool 4 of the belt 1 and is positioned at a predetermined position.

  In the second to sixth embodiments, the shape, material, configuration, etc. common to the first embodiment can be the same as those of the first embodiment.

  The punching device of the above embodiment is an example of an embodiment of the present invention, and other structures, shapes, mechanisms, and the like can be used as long as the object of the present invention can be achieved. For example, the electric drill 5 and the holder 6 can be moved separately.

  The above description is a case where the members necessary for drilling, such as the shell carrier 60, the electric drill 5, the holder 6, the drive mechanism 7, etc. are one set for convenience, but the shell drilling device of the present invention has two of them. This is the case of a pair. As an example of two sets, what is shown in FIG. 12 uses two sets of the same configuration as members necessary for drilling the shell carrier 60, the electric drill 5, the holder 6, the drive mechanism 7, and the like. The shell carrier 60 of the pair of drilling devices is arranged in parallel. Among the members necessary for the drilling, those that can be shared by two sets, for example, the drive device 7 can be shared (shared). When using the drilling device of FIG. 12, the two shell carriers 60 are rotated in the same direction on the same side, and one worker puts the scallop A on the two shell carriers 60 during the rotation. Two workers can place the scallop A on one of the shell carriers 60, or can place the scallop A on the vacant receiving portion 8 of both shell carriers 60. . The two shell transporters 60 may not necessarily have the same rotational direction and rotational speed.

  As an example of two sets, what is shown in FIG. 13 is one in which the shell carrier 60 is doubled inside and outside. Also in this case, necessary members that can be shared by two sets can be shared (shared). In the case of using the drilling device of FIG. 13, one worker can place the scallop A on the inner and outer shell carriers 60, but the two workers can use either the inner shell or the outer shell. The scallop A can be placed on the carrier 60, or the scallop A can be placed on the vacant receiving portions 8 of the inner and outer shell carriers 60.

  The example shown in FIG. 14 as an example of two sets uses two sets of the same configuration as members necessary for drilling, and at least of the two sets of required members, the shell carrier 60 is arranged in the upper and lower stages. It is a thing. Also in this case, necessary members that can be shared by two sets can be shared (shared). When the drilling device of FIG. 14 is used, it is suitable for one worker to place the scallop A on the lower shell carrier 60 and for another one worker to put the scallop A on the upper shell carrier 60. . In this case, when the receiving portion 8 of the lower shell carrier 60 is disposed so as to protrude slightly laterally from the upper shell carrier 60, the operator places the scallop A on the receiving portion 8 of the lower shell carrier 60. The upper shell carrier 60 does not get in the way, and the operator can easily place the scallop A on the receiving portion 8 of the lower shell carrier 60. In the case of FIG. 14, if the tip 60 a of the lower shell carrier is pulled outside the tip 60 b of the upper shell carrier, the operator receives the tip 60 b of the lower shell carrier 60 on the side. When the scallop A is placed on the portion 8, the upper shell carrier 60 does not get in the way, and the operator can easily place the scallop A on the receiving portion 8 on the distal end portion 60 b side of the lower shell carrier 60.

  The members necessary for drilling such as the shell carrier 60, the electric drill 5, the holder 6, and the drive mechanism 7 in FIGS. 12 to 14 have the same configuration and operation as those shown in FIGS. be able to. 12 to 14 are arranged so that one or two workers can easily place the scallop A on the two shell carriers 60.

  Although the two shellfish transport bodies 60 shown in FIG. 12 are formed separately, the two shellfish transport bodies 60 may be accommodated in one housing.
