In the following description of the present embodiment, the vertical direction may be referred to as the up-down direction, and the horizontal direction may be referred to as the left-right direction.

  The cutter device of the present embodiment has two rotating shafts 11 and 12 that are rotatably supported by the base body 10A. The rotary shafts 11 and 12 are on one horizontal line. In other words, as shown in FIG. 3, the central axis C11 of the rotary shaft 11 and the central axis C12 of the rotary shaft 12 are at the same height position. is there.

  Eccentric disks 13 and 14 are fixed to the rotary shafts 11 and 12, respectively. As shown in FIG. 4, the centers Ce of the eccentric disks 13 and 14 are eccentric by the same eccentric amount E with respect to the rotation centers Cd of the rotary shafts 11 and 12. The eccentric amount E of the eccentric disk 13 and the eccentric amount E of the eccentric disk 14 are equal to each other.

  A plate-like member 15 is engaged with the eccentric disks 13 and 14. The plate-like member 15 is a circular locus motion member and has circular fitting holes 16 and 17. The fitting holes 16 and 17 are fitted to the outer circumferences of the eccentric disks 13 and 14 via the rolling bearings 18 and 19 so as to be capable of rotational displacement.

  As a result, the plate-like member 15 has a circular locus motion in which the rotation shafts 11 and 12 maintain a parallel posture (horizontal posture in the present embodiment) by synchronous rotation in the same direction at the same speed. The movement diameter (diameter) of the circular locus movement of the member 15 is twice the eccentric amount E of the eccentric disks 13 and 14.

  Linear guide members (straight guide members) 20 and 21 are fixedly attached to the left and right portions of the plate-like member 15. The linear guide members 20 and 21 are provided in a horizontal posture at the same height position. A strip-like slider 22 that is long in the horizontal direction is engaged with the linear guide members 20 and 21 so as to be linearly movable in the horizontal direction. In other words, the slider 22 is guided by the linear guide members 20 and 21 and supported by the plate-like member 15 so as to be able to reciprocate in the left-right direction.

  The base body 10A supports the crank central shaft 23 in a rotatable manner. One end of a crank arm member 24 is fixedly attached to the crank central shaft 23. One end of the link member 26 is pivotally connected to the tip end (the other end portion) of the crank arm member 24 by a connecting pin 25 so as to be pivotable (rotatable). The other end of the link member 26 is connected to the right end portion of the slider 22 by a connecting pin 27 so as to be pivotable (rotatable). The crank center shaft 23 is arranged at a height position where the center axis C23 of the crank center shaft 23 is different in the vertical direction by a deviation amount D with respect to the center axes C11 and C12 of the rotary shafts 11 and 12.

  A crank mechanism including the crank central shaft 23, the crank arm member 24, and the link member 26 is connected to the slider 22 to form a sliding crank device 28. The sliding crank device 28 reciprocates the slider 22 in the horizontal direction when the crank central shaft 23 is rotationally driven.

  The crank central shaft 23 is drivingly connected to an electric motor 29 that is a driving means, and is rotated by the electric motor 29. Timing belt pulleys 30, 31, and 32 are attached to the crank central shaft 23 and the rotary shafts 11 and 12, respectively. The timing belt pulleys 30, 31 and 32 have the same diameter, and an endless timing belt 33 is stretched around the pulleys 30, 31 and 32. As a result, the crank central shaft 23 and the rotary shafts 11 and 12 are synchronously driven to rotate in the same direction and at the same speed.

  A blade attachment plate 34 is fixedly attached to the slider 22. A plate-like blade 35 is suspended and attached to the blade attachment plate 34 in a replaceable manner. The blade 35 has a substantially horizontal lower edge as a cutting blade 36 equivalent to a Japanese knife. The blade attachment plate 34 passes through a slit opening 37 formed in the base body 10A and a guide member 38 with a slit attached to the base body 10A, and is prevented from shaking in the front-rear direction (left-right direction as viewed in FIG. 2). Yes.

  A bracket 39 is fixed to the base body 10B, and the bracket 39 rotatably supports an intermediate portion of the swing lever 41 by a horizontal pivot 40. The swing lever 41 supports the rotation receiving roll 43 rotatably by a roll shaft 42 at one end. The rotation receiving roll 43 is a workpiece placing member, corresponds to a cutting board, and is located immediately below the blade 35. The rotation receiving roll 43 is made of polyethylene, polypropylene, synthetic rubber or the like.

  The roll shaft 42 is drivingly connected to a servo motor 44. The servo motor 44 intermittently rotates (intermittently feeds) the rotation receiving roll 43 in synchronization with the synchronous rotation drive of the rotary shafts 11 and 12 and the crank central shaft 23 by the electric motor 29 as an intermittent feed mechanism. Thereby, the rotation receiving roll 43 can be intermittently rotated at a required cutting feed pitch in synchronization with the cutting operation by the blade 35.

  The rotation receiving roll 43 changes its arrangement position in the substantially same direction as the cutting direction (vertical direction) of the blade 35 by the cutting blade 36 as the swing lever 41 rotates around the pivot 40.

  The other end of the swing lever 41 is drivingly connected to an operating rod 46 of an electromagnetic actuator 45 attached to the base body 10B by a connecting pin 47. The electromagnetic actuator 45 rotates the swing lever 41 about the pivot 40 of the swing lever 41 to change and set the arrangement position of the rotation receiving roll 43. If the electromagnetic actuator 45 performs an on / off operation like an electromagnetic solenoid device, the arrangement position of the rotation receiving roll 43 can be changed in two steps, upper and lower. If the electromagnetic actuator 45 is linearly operated like a linear actuator, the arrangement position of the rotation receiving roll 43 can be changed steplessly up and down.

  The swing lever 41 is urged in the clockwise direction as viewed in FIG. 2 by a compression coil spring 49 provided between the head of the stud bolt 48 fixedly attached to the base body 10B and the swing lever 41. . An adjustment screw 50 that contacts the other end of the swing lever 41 at the tip is attached to the base body 10B. The adjusting screw 50 finely adjusts the rotational position of the swing lever 41 and finely adjusts the vertical position of the rotation receiving roll 43. Since the arm length between the pivot 40 of the swing lever 41 and the contact portion of the adjustment screw 50 is several times longer than the arm length of the pivot 40 and the roll shaft 42, the rotation receiving roll 43 is arranged in the vertical direction by the adjustment screw 50. The position can be finely adjusted to a minimum.

  The plate-like member 15 is integrally provided with an upper extension 15A. The upper end of the upper extension 15 </ b> A is rotatably connected to the upper end of a strip-like hanging member 53 by a connecting pin 52. A holder member 55 is rotatably connected to the lower end of the hanging member 53 by a connecting pin 54. The holder member 55 has a horizontal portion 55A, and supports the clamp bar 56 in a vertical posture at the left and right ends of the horizontal portion 55A so as to be movable up and down.

  The clamp bar 56 is prevented from falling off the holder member 55 when the fixing ring 57 fixed to the clamp bar 56 contacts the upper surface of the holder member 55. The clamp bar 56 is urged downward by a compression coil spring 59 provided between a fixed spring receiving ring 58 fixed to the clamp bar 56 and the holder member 55.

  The clamp bar 56 can be displaced upward relative to the holder member 55 against the spring force of the compression coil spring 59. A movable spring receiving ring 60 and a sleeve member 61 are sandwiched between the compression coil spring 59 and the holder member 55.

  Since these mechanisms are located in front of the plate-like member 15, these portions are not shown in FIG. 1 so that the configuration of the plate-like member 15 can be clearly understood.

  The clamp bar 56 passes through a through hole 62 formed in the base body 10A and a guide sleeve member 63 attached to the base body 10A, and is held so as to be movable up and down. A pressing member 64 that holds a workpiece such as fish meat against the upper outer peripheral surface of the rotation receiving roll 43 is attached to the lower end portion of the clamp bar 56. The holding member 64 has a bowl-shaped cross-sectional shape so as to hold the workpiece as close as possible to the cutting position of the cutting tool 35 by the cutting blade 36.

  In FIG. 2, reference numeral 70 denotes a feeding belt conveyor, 71 denotes a fixed guide member that delivers a workpiece from the feeding belt conveyor 70 onto the rotation receiving roll 43, 72 and 73 denote feeding rollers, and 74 denotes a feeding belt conveyor. Are shown respectively.

  The feed belt conveyor 70, the feed rollers 72 and 73, and the feed belt conveyor 74 may be operated continuously, depending on the feed speed of the workpiece. The feed belt conveyor 70 and the feed rollers 72 and 73 It may be driven intermittently in synchronization with the cutting operation by the blade 36.

  In the present embodiment, a workpiece such as fish meat is fed to the upper outer peripheral surface of the rotation receiving roll 43 by the feed belt conveyor 70 and the feed rollers 72 and 73.

  When the crank shaft 23 and the rotary shafts 11 and 12 are synchronously driven in the clockwise direction by the electric motor 29 from the cutter ascending position shown by the solid line in FIG. The member 15 descends while drawing a circular locus motion. At the same time, due to the rotation of the crank central shaft 23, the slider 22 moves down to the right side and then moves to the left side while moving downward slightly as the plate-like member 15 moves down. As a result, the blade 35 moves to the left while descending, and moves to the cutter descend shown by the phantom line in FIG. 1 while drawing a gentle arc.

  As a result, the crank central shaft 23 and the rotary shafts 11 and 12 are synchronously driven in the same direction, so that the plate-like member 15 rises while drawing a circular locus motion. At the same time, the slider 22 moves horizontally to the right while moving up as the plate-like member 15 moves up. As a result, the cutter 35 moves upward while moving upward, and returns to the original cutter rising position indicated by the solid line in FIG. 1 while drawing a gentle arc.

  As described above, the blade 35 moves by combining the circular locus motion and the sliding crank motion, and the movement of the blade 35 is an ellipse or an ellipse obtained by extending the circular locus motion laterally by the sliding crank motion. It becomes an exercise that draws a similar trajectory. The cutting edge 36 of the blade 35 is cut by cutting a workpiece such as fish fed to the upper outer peripheral surface of the rotation receiving roll 43 by a movement locus on the long axis side of a locus similar to an ellipse or an ellipse. A cut similar to that of a kitchen knife will be made.

  By cutting, cut cooking of fish meat sashimi and the like is carried out electrically without crushed fish cells, with a beautiful cut surface, and without requiring manpower and skill.

  The movement trajectory of the cutter 35 is the vertical direction between the eccentric amount E of the eccentric disks 13 and 14, the arm length of the crank arm member 24, the central axis C23 of the crank central shaft 23 and the central axes C11 and C12 of the rotary shafts 11 and 12. By setting the amount of deviation D and the relative rotational phase difference between the eccentric disks 13 and 14 and the crank arm member 24, a desired movement locus or a movement locus approximate thereto can be obtained.

  Further, by rotating and rotating the rotating shafts 11 and 12 of the eccentric disks 13 and 14 and the crank central shaft 23 individually by individual servo motors or the like, the motion locus of the blade 35 can be set with a high degree of freedom. .

  Further, when cutting the fish 35 by the cutting blade 36 of the blade 35, the workpiece 64 such as fish meat is cut into a cutting board equivalent at the position where the holding member 64 is very close to the cutting position by the cutting blade 36 in synchronization with the cutting operation. Since the workpiece is pressed against the upper outer peripheral surface of the rotation receiving roll 43, the workpiece is not moved in the cutting with the cutting edge 36, and straight in the moving direction of the cutting edge 36 (the same direction as the axial direction of the rotation receiving roll 43). It cuts cleanly.

  In addition, fine circumferential grooves may be provided on the outer peripheral surface of the rotation receiving roll 43 with a predetermined pitch in the roll axis direction, so that fish or the like may be difficult to slide in the axial direction of the rotation receiving roll 43. Moreover, the outer peripheral surface of the rotation receiving roll 43 may be a rough surface due to fine irregularities.

  The force with which the pressing member 64 presses the workpiece against the upper outer peripheral surface of the rotation receiving roll 43 can be set to an optimum value according to the hardness of the workpiece by the spring force of the compression coil spring 59. By bending the compression coil spring 59, it is possible to avoid an excessive pressing force from acting on the workpiece. For example, in cut cooking of fish meat and the like, it can be set to an optimum value such that the fish meat is pressed by human hands.

  The depth of cutting of fish or the like by the cutting blade 36 of the blade 35 can be changed to an appropriate value by adjusting the height position of the rotary receiving roll 43 relative to the cutting blade 36 by the electromagnetic actuator 45 and the adjusting screw 50.

  For example, in cut cooking for cutting off sashimi or the like, a sufficient cutting depth may be set by moving the rotary receiving roll 43 to the raised position by the electromagnetic actuator 45. On the other hand, in cut cooking that leaves one skin, such as cutting bones, the electromagnetic actuator 45 moves the rotation receiving roll 43 to the lowered position, and the adjustment screw 50 finely adjusts the lowering position of the rotation receiving roll 43. Then, it is only necessary to set a delicate cut depth to leave a skin. This delicate adjustment of the cut depth can be performed by the adjusting screw 50 while performing the cutting operation and watching the state.

  The cut pitch of the cut cooking that leaves the skin like bone cutting can be freely set to an appropriate value and a desired value according to the rotation speed and intermittent feed speed of the rotation receiving roll 43 synchronized with the cutting operation by the blade 35. In such cut cooking, the rotation receiving roll 43, the feeding rollers 72 and 73, and the feeding belt conveyor 70 are all intermittently operated in synchronization with the cutting operation by the blade 35. Desirable in obtaining.

  In the cut cooking that leaves the skin, the rotation receiving roll 43 is moved to the raised position by the electromagnetic actuator 45, so that it can be cut to a certain length.

  As described above, the cutting tool 35 moves in a manner equivalent to the slicing, so that the sashimi such as fish and cuts can be cut well, and delicate cuts such as cutting the bones of the sword can also be performed by the chef. It becomes possible to do appropriately without depending.

  In the above-described embodiment, two parallel eccentric disks 13 and 14 are used as the mechanism for performing the circular locus motion while maintaining the parallel posture, but the mechanism for performing the circular locus motion is as shown in FIG. A four-bar linkage mechanism using two parallel link members 81 and 82 can also be used.

  In FIG. 5, parts corresponding to those in FIG. 1 are denoted by the same reference numerals as those in FIG.

  Other embodiments of the cutting device according to the present invention include the following.

  (1) The deviation D in the vertical direction between the central axis C23 of the crank central shaft 23 and the central axes C11 and C12 of the rotary shafts 11 and 12 is set to zero. In this case, as shown in FIG. 6, the center axis C23 of the crank center shaft 23 and the center axes C11 and C12 of the rotary shafts 11 and 12 are aligned in a straight line at the same height position. In this case, an idle / tension timing belt pulley 65 may be provided, and the timing belt pulleys 31, 32, 33 and the idle / tension timing pulley 65 may be stretched over the timing belt 33.

  (2) The rotation receiving roll 43 is moved up and down by a feed screw mechanism in the vertical axis direction, a linear actuator or the like.

  (3) As shown in FIG. 7, the cutting position of the blade 35 relative to the outer peripheral surface of the rotation receiving roller 43 is perpendicular to the cutting direction by the cutting blade 36 with respect to the rotation center C43 of the rotation receiving roller 43. In addition, the rotation receiving roller is biased by a predetermined amount (bias amount) e in the radial direction.

  As described above, when the cutting position of the blade 35 is deviated, the cutting blade 36 is inclined at an inclination angle θ (FIG. 8) with respect to the cut piece (workpiece) such as a ridge carried along the outer peripheral surface of the rotation receiving roller 43. (Refer to) and go into the slant and cut off. The degree of cutting can be set by the amount of deviation e.

  This deviation amount e may be adjustable because the rotation receiving roller 43 is provided so that its arrangement position can be changed in a direction orthogonal to the cutting direction by the cutting blade 36. Further, the blade 35 may be provided so that the arrangement position thereof can be changed in a direction orthogonal to the cutting direction by the cutting blade 36 with respect to the rotation receiving roller 43.

  The sawing can also be realized by the cutting direction of the cutting blade 36 with respect to the rotation receiving roller 43 being inclined with respect to the normal to the roller outer peripheral surface.

The worm 83 is drivingly connected to the cutter tilting electric motor 87 by the timing belt pulley 84, the timing belt 85, and the timing belt pulley 86, and is rotationally driven by the cutter tilting electric motor 87.

  As a result, the support housing 80 is driven to rotate about the cutting bottom dead center position A of the cutting tool 35 by the cutting tool electric motor 87, and is arbitrarily rotated by the engagement between the worm wheel 82 and the worm 83. It is held (fixed) at the position (tilted position).

A plate-shaped cutting plate member 90 which is a workpiece mounting member is provided at a position below the blade 35. The chopping plate member 90 is engaged with the upper and lower elongated holes 93 of the elevating support member 92 with pins 91 and can be displaced up and down. One end of a pivot arm member 95 having a pivot 94 as a pivot center is pivotally connected to the pin 91. A nut 96 is attached to the other end of the rotating arm member 95,
An adjusting screw 97 is threadedly engaged with the nut 96. Thereby, the arrangement position of the cutting board member 90 in the vertical direction can be adjusted by the adjusting screw 97, and the cutting depth can be variably set.

  A transport conveyor device 110 is disposed on the base 100. The transport conveyor device 110 has endless belts 116 made of rubber that are stretched over end rollers 111 and 112, a driving roller 113, and guide rollers 114 and 115. The drive roller 113 is drivingly connected to the conveyor electric motor 120 by the timing belt pulley 117, the timing belt 118, and the timing belt pulley 119, and is driven to rotate counterclockwise in FIGS. 9 and 10 by the conveyor electric motor 120. The As a result, the upper path portion between the end rollers 111 and 112 of the endless belt 116 travels from the right to the left in FIGS.

  The end roller 111 is on the front side (right side in FIGS. 9 and 10) of the cutter 35 when viewed in the traveling direction of the upper path portion of the endless belt 116, and the other end roller 112 is on the other side of the cutter 35 ( 9 and 10 on the left side). As a result, the transfer conveyor device 110 extends across the cutting position (cutting bottom dead center position A) by the cutting tool 35, and is directed to the cutting position by the cutting tool 35 between the end roller 111 and the cutting position by the cutting tool 35. 110 A of infeed conveyance parts which convey a work piece in this way, and send out conveyance which conveys a work piece from the incision position by a blade 35 to a sending belt conveyor 74 between a cut position by a blade 35 and an end roller 112 Part 110B is configured.

  The end roller 111 is located at a lower position than the cutting board member 90, whereby the infeed conveyance unit 110A is an inclined conveyance surface (upper surface upper surface) inclined upward toward the cutting position by the cutter 35. The end roller 111 may be provided so that its arrangement position can be changed in the vertical arc direction. Thereby, the infeed conveyance unit 110A can variably set the inclination angle of the upward gradient.

  A rubber pressing endless belt 130 is provided between the large and small rollers 131 and 132 on the workpiece feeding side of the cutting position by the blade 35. The roller 131 is rotationally driven by the electric motor 133 in the clockwise direction as viewed in FIGS. As a result, the underpass portion of the endless belt 130 moves at substantially the same traveling speed in the same direction as the upper pass portion of the endless belt 116.

  The roller 132 is smaller in diameter than the roller 131 and is in a position very close to the cutting position by the blade 35. Furthermore, the arrangement position of the roller 132 can be displaced up and down, and the roller 132 is urged downward (underpass portion side of the endless belt 130) by a spring means (not shown). This spring force becomes an elastic pressing force of the workpiece by the pressing endless belt 130.

On the side of the end roller 111 of the base 100, a water absorbent sheet roll 150 around which a long belt-shaped water absorbent sheet 151 is wound is disposed so as to be replaceable by a bracket 152. The water-absorbing sheet 151 is, for example, a multiple sheet in which a water candy component, which is a high osmotic pressure food, and a seaweed component (glue) that holds the absorbed water are sandwiched between two polyvinyl alcohol films. , And a separation perforation 153 extending in the width direction at a predetermined interval in the longitudinal direction. The water absorbent sheet 151 is fed out from the water absorbent sheet roll 150 and laid (placed) on the upper path portion of the endless belt 116 from the end roller 111 side along the conveying direction.
In addition, the water absorbing sheet 151 is not limited to the above-described multiple sheet, and may be a paper having excellent water absorption.

  Work pieces, for example, fish of small fish such as salmon, are placed on the water-absorbing sheet 151 in the feeding / conveying section 110A in a state of being arranged in a plurality of pieces, and directed to the cutting position by the blade 35 by the endless belt 116. Sent in. The fish meat on the water absorbing sheet 151 is combined with the circular locus motion and the sliding crank motion in the same manner as in the first embodiment in a state where the fish meat is elastically pressed toward the upper surface of the upper path portion of the endless belt 116 by the pressing endless belt 130. The blade is cut by the cutting edge 36 at the lower edge of the cutting tool 35 that moves, and cut into a size corresponding to sashimi (sashimi cutting).

  The fish meat on the water-absorbing sheet 151 that has been cut into sashimi is continuously fed toward the feed belt conveyor 74 by the endless belt 116.

  Here, since the belt traveling speed of the delivery belt conveyor 74 is higher than the traveling speed of the endless belt 116, the water absorbent sheet 151 transferred to the delivery belt conveyor 74 from the endless belt 116 is pulled in the belt traveling direction. Thereby, the water absorption sheet 151 is cut off with the cut perforation 153. The separated water absorbent sheet 151 may have a size corresponding to the size of the sales tray, and can be used as it is as an underlay sheet for the sales tray.

  In this way, the processed water-absorbing sheet 151 on which the sashimi-cut fish meat is placed is used as it is as an underlay sheet for a sales tray, so that the trouble of rearrangement can be saved, and at the same time, the rearrangement of the fillet becomes “ It does not become loose, and can be put into a distribution sales tray in a sashimi-cut appearance. This saves the labor of rearrangement and also prevents the freshness of sashimi from being rearranged.

  In sashimi cutting as described above, the support casing 80 is rotated about the cutting bottom dead center position A of the blade 35 by the electric motor 87 for blade inclination, so that the blade is in accordance with the rotation angle. The cutting direction of 35 is inclined with respect to the vertical plane (vertical plane), and cutting is performed.

  Such chopping increases the flat area of each slice of sashimi, such as salmon, and increases the added value of small fish as a sashimi dish. By these things, it can be expected that the bottleneck of the distribution of small fish sashimi will be eliminated and the distribution of small fish sashimi will become popular.

  As shown in FIG. 11, in this cutting, the cutting angle θa (the angle with respect to the horizontal plane) where the blade 35 enters the fish meat is determined by the rotation angle θd of the support housing 80 by the blade tilting electric motor 87, and θa = (90−θd). The degree of sawing is stronger when the sawing angle θa is smaller. The degree of sawing is increased by the upward slope of the infeed conveyance unit 110A. As shown in FIG. 11, when the inclination angle of the ascending slope of the feeding conveyance unit 110A is θb, the sawing angle θc at this time is (θa−θb).

  Since the rotation center axis C103 of the support housing 80 is at the cut bottom dead center position A of the blade 35, the cut bottom dead center position of the blade 35 is changed even if the rotation angle θd of the support housing 80 changes. There is no change, and even if the rotation angle θd of the support housing 80 is changed, there is no need to adjust the cutting depth of the blade 35.
