  Here, operations of the punching device M and the punching cutter C configured as described above will be described.

  First, the operator operates the automatic / manual selection button of the operation box 43 of the punching device M to select whether to perform automatic operation or manual operation.

  Here, the case of operating in automatic operation will be described.

  When the automatic operation is started, the operator operates the emergency stop button 44a of the emergency operation box 45 to release the emergency stop state. At this time, the inside of the apparatus M is visually inspected, and if foreign matter, shavings, or the like remain, they may be removed.

  Note that when the cutting cutter C is not at the origin position, the origin return button of the operation box 43 is operated.

  Next, an object 100 (for example, a peeled onion or a jaguar) 100 to be cut is placed on the holder mechanism H.

  Here, when the operator presses the start button with both hands, the operation of the punching device M is started.

  First, the rotation motor 32 is activated, and the blade body 50 of the cutting cutter C starts to rotate forward. Next, the elevating motor 20 is activated and the elevating frame F starts to descend. Thereby, the cutting cutter C continues to descend while the blade 51 cut in the axial direction cuts the object 100 downward.

  When the operating position of the hollow blade mechanism K is detected by the first sensor SE1, the air cylinder device 30 is activated by the control of the control device 200 based on the detection signal, and the hollow blade mechanism K operates.

  More specifically, the rod 300 of the air cylinder device 30 protrudes downward, and the operating rod 53 connected to the tip of the rod 300 moves downward against the biasing force of the spring 56 ((A in FIG. 6 ) In the direction of arrow A). As a result, the link mechanism L is activated, and the hollow blade main body 54 has advanced outward from the communicating opening 55 from the housed state in the hollow portion 52 (the state of FIG. 6A) (FIG. 6). (B) state).

  Then, by continuing the rotation and lowering of the blade body 50 in a state in which the cut-out blade body 54 is projected from the blade body 50, a cut-out portion 500 is formed in the object 100 as shown in FIG. .

  At this time, shavings such as pulp by the blade body 50 and the cut-off blade body 54 are guided upward by a spiral groove 57 formed on the peripheral surface of the blade body 50 and discharged to the outside. Processing is performed efficiently.

  Next, when the lower limit position of the cutting cutter C is detected by the third sensor SE3, the rod 300 of the air cylinder device 30 is retracted by the control of the control device 200 based on the detection signal, and the operating rod 53 is The spring 56 is raised by the urging force of the spring 56 and returns to the original position. Thereby, the hollow blade main body 54 is accommodated in the hollow portion 52 of the blade main body 50 by the action of the link mechanism L.

  Further, under the control of the control device 200, the elevating motor 20 rotates in the reverse direction, the punching cutter C rises, and the cutter C retracts from the object 100.

  Through the above-described operation, the target object 100 such as a peeled onion or a jaguar that forms the cut-out portion 500 as shown in FIG. 9 can be obtained accurately and efficiently.

  Next, when the position at which the holder mechanism H operates is detected by the fourth sensor SE4, the open / close motor 43 is activated by the control of the control device 200 based on the detection signal, and the hand members 42a and 42b are opened downward. Is done. Thereby, the object 100 is released downward, flows down through the inclined plate 60, and is collected on the rear side of the apparatus M.

  When the rising limit position of the hollow cutter C is detected by the third sensor SE3, the lifting motor 20 and the rotary motor 32 are stopped by the control of the control device 200 based on the detection signal, and the hollow machining is performed. All processes are completed.

  If the same punching process is subsequently performed on the plurality of objects 100, the above-described operation is repeated.

  Further, when any abnormality such as clogging is generated in the middle of the cutting process, the operator operates the emergency stop button 44a of the emergency operation box 45 so that the control device 200 immediately All of the lifting motor 20, the rotating motor 32, etc. are urgently stopped, a buzzer is sounded, and the abnormality notification lamp 44b is turned on to notify the occurrence of an abnormality to the surroundings. Thereby, the safety | security in a hollow process can be ensured.

  Note that, although not particularly limited, the object 100 (such as onions, vegetables or fruits including potatoes) that has been subjected to the hollowing process by the hollowing apparatus M according to the present embodiment 100 is cut out ( It can be set as the processed food which stuffed ingredients, such as a gratin ingredient | tool ingredient | tool or jam, in FIG.

  Furthermore, the processed food can be repackaged by predetermined packaging or the like, or can be cooled to be frozen food or chilled food.
