  Hereinafter, the cutting machine 10 according to the present invention will be described in detail with reference to the drawings.

  First, the structure of the cutting machine 10 is demonstrated using FIGS. In the cutting machine 10, food is disposed on a cutting board 12 installed on a housing 21. The blade 13 of the knife 14 is disposed above so as to face the placement surface 11 of the cutting board 12. The knife 14 reciprocates around the rotating shaft 15. The rotating shaft 15 is driven by a motor 60 in the housing 21. The motor 60 transmits the power to the rotary shaft 15 via the gear box 61.

  The knife 14 is fixed to a rotation shaft 15 and a slide shaft 16 parallel to the rotation shaft 15. The knife 14 can slide in the axial direction with respect to both the rotation shaft 15 and the slide shaft 16. The slide shaft 16 and the rotation shaft 15 are connected to a fixed plate 18 with each other. The stopper 20 is provided along the edge (side edge) of one end portion of the placement surface 11. The food material is pressed against the pressing surface 19 of the stopper 20 to position the food material before cutting.

  A total of four legs 22 and 23 are provided at the lower portion of the housing 21. The pair of legs 22 has a fixed length, and the other pair of legs 23 is variable in length (expandable). On the upper surface of the housing 21, a control box 25 is provided for overall control of the entire machine. A safety glove 26 for preventing the operator's hand from being cut is connected to the control box 25 by a conductive wire. The knife 14 is provided with an operating device 27 for manual operation.

  The chopping board 12 includes a chopping board main body 31 that constitutes the food placement surface 11, and a long elongated piece 32 that protrudes upward along the front edge of the board main body 31. The long piece 32 prevents the food material from dropping to the near side. The knife 14 includes a blade body 33 having a rectangular plate shape, a mounting plate 34 for fixing the blade body 33 with bolts, and sliding bearings 35 and 36 provided on the mounting plate 34. A blade 13 is formed on the lower edge of the blade body 33.

  Sliding bearings 35 and 36 are provided on the mounting plate 34, and the rotating shaft 15 or the slide shaft 16 is inserted into the mounting plate 34, respectively. The slide bearing 36 on the slide shaft 16 side is provided with a fixing screw 17 that fixes itself to the slide shaft 16. When the fixing screw 17 is screwed in, the knife 14 itself is fixed to the slide shaft 16. When the fixing screw 17 is loosened, as shown in FIGS. 3A and 3B, the knife 14 slides along the rotation shaft 15 and the slide shaft 16, and the interval (d1, d2), that is, the cutting width of the food can be adjusted.

  When the rotation shaft 15 rotates in one direction, as shown in FIG. 2B, the knife blade 13 moves in a direction away from the placement surface 11 of the cutting board 12 (this is referred to as “separation”). Called "position"). When the rotation shaft 15 further rotates in the other direction, the blade 13 of the knife 12 abuts against the placement surface 11 of the cutting board 12 as shown in FIG. 2A (this is referred to as “cutting position”). ).

  The rotation shaft 15 passes through the fixed plate 18. The rotating shaft 15 and the fixed plate 18 are fixed by welding or the like. The fixed plate 18 holds the slide shaft 16 so as to be parallel to the rotation shaft 15. Therefore, when the fixed plate 18 swings with respect to the rotation shaft 15, the slide shaft 16 also swings about the rotation shaft 15.

  The stopper 20 is a stainless steel plate shaped like a fan, and is fixed to the fixed plate 18 by welding. The stopper 20 is arranged in parallel to the blade 13 of the knife 14. When the rotation shaft 15 rotates in one direction, the stopper 20 moves upward and protrudes above the cutting board 12 as shown in FIG. As a result, the pressing surface 19 of the stopper 20 is positioned higher than the placement surface 11 and the food can be pressed (this is referred to as a “pressable position”). When the rotation shaft 15 rotates in the other direction, the stopper 20 moves downward and is hidden under the cutting board 12 as shown in FIG. As a result, the pressing surface 19 of the stopper 20 is retracted to a position lower than the placement surface 11 of the cutting board 12 (this is referred to as “retreat position”). The upper end edge of the stopper 20 at the retracted position is slightly lower than the placement surface 11 of the cutting board 12.

  In this way, the knife 14 and the stopper 20 are held together on the rotating shaft 15, the slide shaft 16 and the fixed plate 18, and the stopper 20 and the knife 14 are interlocked. When the knife 14 is in the “separation position”, the stopper 20 is in the “pushable position” (see FIG. 2B), and when the knife 14 is in the “cutting position”, the stopper 20 is in the “retracted position” ( (See FIG. 2A).

  A pair of elongated holes 37 extending in the vertical direction are formed in the side surface of the housing 21, and the pair of adjusting screws 24 slide up and down in the pair. The fixed leg portion 22 is a pair of rubber legs, and is fixed to the lower portion of the housing 21. As shown in FIG. 4, the extendable leg portion 23 includes an L-shaped plate 38 formed in an L-shape and a pair of rubber legs 39 fixed to the lower bottom surface of the L-shaped plate 38. A pair of adjustment screws 24 are fastened to the side surface of the L-side plate 38. The L-shaped plate 38 is fixed to the side surface of the housing 21 by the adjusting screw 24. When the adjustment screw 24 is loosened and slid in the vertical direction along the long hole 37 of the housing 21, the L-shaped plate 38 slides relative to the housing 21, and the leg portion 23 expands and contracts. If the adjustment screw 24 is tightened at an appropriate position, the casing 21 and the L-shaped plate 38 are fixed, and the length of the leg portion 23 is fixed. As a result, a “horizontal position” (see FIG. 4A) where the mounting surface 11 of the cutting board 12 is horizontal (see FIG. 4A) and an “inclined position” where the mounting surface 11 of the cutting board 12 tilts (FIG. 4B). Can be adjusted freely. At this inclined position, the stopper 20 (pressing surface 19) side is the lower side.

  The control box 25 includes an internal control unit, a keyhole 42 for inserting a start key, an operation button 43, a stop button 44, an emergency stop button 45, a power indicator 46, and a speed adjustment dial 47. Yes. When the starting key is inserted into the keyhole 42, the power indicator 46 is lit and the power is turned on. When the operation button 43 is pressed in this state, the automatic cutting operation starts. When the stop button 44 is pressed, the automatic cutting operation stops. When the emergency stop button 45 is pressed, the operation is completely stopped and the power indicator 46 is turned off. The cutting machine 10 that has completely stopped cannot resume operation unless the starting key is reinserted into the keyhole 42. The operation speed can be adjusted by the speed adjustment dial 47.

  The safety glove 26 is formed of a wire mesh that cannot be cut even by the knife 14, and is connected to the control box 25 via a conductive wire. The safety gloves 26 are worn by the operator. When the safety gloves 26 touch the knife 14, the control box 25 is energized and the cutting machine 10 is forcibly stopped.

  The operating device 27 used in the manual cutting operation is disposed on the upper edge of the attachment plate 34 of the knife 14. As shown in FIG. 5A, the operating device 27 includes a case 51 having a long shape, first and second sensors 52 and 53 disposed in the case 51, and a tip (work) of the case 51. A handle 54 attached to the person side). The first and second sensors 52 and 53 are connected to the control box 25 via signal lines.

  The handle 54 includes a handle main body 55, a support shaft 56, a pair of coil springs 57, and a pair of sponge pieces 58. The handle body 55 is formed with a pair of upper and lower grooves, and a pair of coil springs 57 are fitted therein. The support shaft 56 is fixed to the inner surface of the case 51 in the horizontal direction. As a result, the handle 54 swings in the vertical direction with the support shaft 56 as a fulcrum. The pair of sponge pieces 58 are interposed in the upper and lower gaps of the case 51 of the handle body 55. When the handle body 55 is swung by the elastic force of the sponge piece 58 and the pair of coil springs 57, an appropriate reaction force (restoring force) that returns to the neutral side is generated. When the operator pulls the front side of the handle 54 upward, the inside of the case 51 of the handle 54 swings downward and contacts the first sensor 52 (see FIG. 5B). As a result, the first sensor 52 detects that the handle 54 swings upward. The signal from the first sensor 52 is a signal for moving the knife 14 upward. On the other hand, when the operator pushes the front side of the handle 54 downward, the inside of the case 51 of the handle 54 swings upward and comes into contact with the second sensor 53 (see FIG. 5C). As a result, the second sensor 53 detects that the handle 54 swings downward. The signal from the second sensor 53 is a signal for moving the knife 14 downward.

  As described above, when the handle 54 of the operating device 27 is pushed downward, the knife 14 moves downward and cuts the food only during the pushing. If the handle 54 of the operating device 27 is pulled up, the knife 14 moves upward only during that time to release the food (manual cutting function). Even during the automatic cutting described later, if the operation device 27 is touched, the manual cutting function can be automatically switched.

  Next, an automatic cutting procedure of the cutting machine 10 will be described. In the initial state, the knife 14 is in the “cutting position” and the stopper 20 is in the “retracting position” (see FIG. 6A). The operator wears the safety gloves 26 and operates the speed adjustment dial 47 to adjust the driving speed. Further, the tray YA1 is placed on the upper surface of the casing 21, and the food material XA1 is placed on the placement surface 11 of the cutting board 12 (see FIG. 6B). Thereafter, when the operator inserts a starting key into the keyhole 42 and presses the operation button 43, the knife 14 starts to reciprocate. The operator presses the food material XA1 against the pressing surface 19 of the stopper 20 in view of the timing (see FIG. 7A) when the knife 14 is in the “separation position” and the stopper 20 is in the “pushable position” (see FIG. 7A). 7 (B)). Thereafter, the knife 14 moves to the “cutting position” to cut the food material XA1 (see FIG. 8A). In conjunction with this cutting operation, the stopper 20 moves to the “retracted position”. As a result, the cut food material XA1 is released from the stopper 20 and discharged in a direction away from the kitchen knife 14 by its own weight (see FIG. 8B). Thereafter, the knife 14 moves to the “separation position” and the stopper 20 moves to the “pushable position” (see FIG. 9). By repeating these operation procedures, the food material XA1 is continuously cut.

  According to this cutting machine 10, the food material XA1 is cut so that the blade 13 of the knife 14 abuts the cutting board 12. As a result, the cutting force can be stably applied to the food material XA1 from the start of cutting to the end of cutting. As a result, it is possible to prevent the corner of the food material XA1 from being cut off at the end of cutting. Further, since the food material XA1 can be positioned and cut on the pressing surface 19, the posture of the food material XA1 being cut becomes stable and a beautiful cut surface. Since the stopper 20 is automatically retracted almost simultaneously with the cutting of the food material XA1, the food material XA1 after cutting can be quickly discharged. Furthermore, since the knife 14 is rotated (oscillated) by the rotation shaft 15, the blade 13 can be inserted obliquely with respect to the food material XA1, so that the force applied to the blade 13 can be reduced and the food material XA1 can be cut smoothly. .

  Furthermore, since the leg part 23 can be extended and the cutting board 12 can be tilted, the cut food material XA1 can be discharged away from the knife 14 by its own weight. Further, since the operation device 27 is provided, even an unskilled worker can operate the cutting machine 10 as if using a normal knife. The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit and technical idea of the present invention.
