A tool hole forming method that can be prevented can be easily provided.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. Reference numeral 1 shown in the figure denotes a rice P filled in a rice ball forming mold on a turntable Q in the rice ball forming apparatus. A tool hole forming device for forming a tool hole S with respect to the tool hole forming device 1. The tool hole forming device 1 includes an elevating block 2 that is movable in the vertical direction above the tool hole forming die V of the turntable Q, and an elevator. A lifting rod 3 that is biased downward with respect to the block 2 and that can be pressed and moved upward while rotating against this biasing force, and provided at the lower side of the lifting rod 3 and rotated at an arbitrary angle. It is generally composed of a rotating mechanism portion R in which a tool hole punching plate 4 that can be provided is arranged on the lower side.

  As shown in FIG. 1, the elevating block 2 is fixed to an elevating member 15 that can be moved up and down by an unillustrated elevating device, and is moved up and down while being guided by a pair of guide rods 5 fixed to a rotating mechanism portion R described later. It is formed by the cylinder which enabled. In addition, a pair of spiral grooves 6 opened on the lower end side of the lifting block 2 are formed in the lower left and right symmetrical places on the lower surface of the lifting block 2 in order to engage guide pins 7 of the lifting rod 3 described later. Has been.

  The elevating rod 3 is inserted into the cylinder of the elevating block 2, and the upper end of the elevating rod 3 is locked on the upper surface side of the elevating block 2 by fitting a large diameter washer member 8. Further, a guide pin 7 projects from the inner side of the outer peripheral surface of the lifting / lowering rod 3 so as to correspond to the spiral groove 6 and engages with the spiral groove 6 from the inside. And the spring 9 wound by the raising / lowering rod 3 is provided so that each of the raising / lowering block 2 and the rotation mechanism part R may be urged | biased in the expansion direction.

  That is, a spring 9 is wound around a lifting rod 3 that extends below the lifting block 2, and the lower end side of the lifting rod 3 is placed through the spring 9 at the center of the upper plate 12 in the rotation mechanism portion R described later. It is inserted through the insertion hole. At this time, since the upper end portion of the lifting rod 3 is locked to the upper surface side of the lifting member 15 above the lifting block 2 by the washer member 8, the upper plate 12 itself is attached to the lower side along the lifting rod 3 by the spring 9. The upper plate 12 itself is prevented from being detached by being locked by the upper surface of a main driving gear 10 (described later) attached to the lower end portion of the elevating rod 3.

  The rotating mechanism R is connected via a pair of guide rods 5 so that the upper plate 12 inserted into the lower end of the lifting rod 3 can slide up and down together with the lifting rod 3 with respect to the lifting block 2 side. Further, a substantially triangular lower plate 13 is spaced from the upper plate 12 via a support column 17, and three rotary shafts 16 each having a driven gear 11 are rotatably pivoted between them. It is worn. Between the upper plate 12 and the lower plate 13, the driven gear 11 is meshed at intervals of 60 degrees around the main driving gear 10 fixed to the tip of the lifting rod 3. Moreover, the lower end of each rotating shaft 16 is protruded below the lower plate 13, and the tool hole punching plate 4 is attached thereto with the flat portion sideways.

  In addition, each of the triangular vertex positions of the lower plate 13 is provided with a stopper portion 14 by screwing a screw material or the like so that the rotating mechanism R is locked onto the turntable Q as the elevating block 2 is lowered. The tool hole punching plate 4 to be inserted into P is stopped at a predetermined insertion position.

  Thus, as the elevating block 2 is lowered, the three tool hole punching plates 4 below the rotation mechanism R are inserted into the rice P in the tool hole forming die V from one end side, and after the insertion, these tool hole punching plates are inserted. A tool hole S is formed by horizontally rotating 4 and retracting the rice P by 4 degrees. In the present embodiment, the number of the perforated plates 4 is three. However, the number is not limited to this, and may be one or two, or even four or more. The tool hole punching plate 4 is formed in a thin plate shape. Specifically, a thickness of about 1 to 3 mm is suitable.

  Next, the use and operation in this configuration will be described. When the turntable Q rotates intermittently and the tool hole forming die V moves below the tool hole forming device 1, the lifting member 15 is moved by the lifting device (not shown). The raising / lowering block 2, the raising / lowering rod 3, and the rotation mechanism part R each descend | fall integrally. Then, as shown in FIG. 2, the lower end of the stopper portion 14 abuts on the turntable Q, and the three tool hole punching plates 4 are inserted into the upper surface of the rice P in the tool hole forming die V.

  Next, as shown in FIGS. 3 and 4, when the elevating member 15 and the elevating block 2 are pushed down against the pressure expansion elastic force of the spring 9 by the elevating device, the spring 9 is compressed and the guide pin of the elevating rod 3 is pressed. 7 moves to the upper side of the lifting block 2 along the spiral groove 6, the lifting rod 3 rotates, and the peripheral driven gear 11 rotates simultaneously with the rotation of the main driving gear 10 in the rotating mechanism R. As a result, as shown in FIG. 5, the three perforated plates 4 horizontally rotate 60 degrees in the same rotational direction about the rotation shaft 16 of the driven gear 11 to bring the central rice P to the surroundings. Thereafter, when the elevating member 15 and the elevating block 2 are raised, the three plate holes 4 return to their original positions before the rotation, and as shown in FIG. S is formed.

7 and 8 show other examples of the present embodiment.
In addition, the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol to the same part as the structure in above-described form. In the present embodiment, instead of the gear rotation type rotation mechanism R, a cam rotation type rotation mechanism R is provided. That is, instead of the main driving gear 10, a rotating block 22 having locking pins 21 fixed at intervals of 60 degrees is attached to the lower end of the elevating rod 3, and a grooved cam is installed on the rotating shaft 16 instead of the driven gear 11. A block 23 is attached. At this time, one end of the grooved cam block 23 is fixed to the rotating shaft 16, and the locking pin 21 is engaged with the groove portion 24 formed at the other end of the grooved cam block 23. The grooved cam block 23 is rotated by the locking pin 21 rotating together with the rotation block 22 in this manner, whereby the three tool hole punching plates 4 are horizontally rotated by 60 degrees to retract the rice P, thereby forming the tool hole S. It is like that.

9 and 10 show still another example in the present embodiment.
In addition, the detailed description is abbreviate | omitted by attaching | subjecting the same code | symbol to the same part as the structure in above-described form. In the present embodiment, the rotary block 22 can be moved up and down in the linear direction with respect to the upper plate 12 of the rotary mechanism R without using the elevating block 2 having the spiral groove 6. Then, three locking pins 21 are fixed to the outer peripheral surface of the lower end of the lifting rod 3 in place of the main driving gear 10 at intervals of 60 degrees around the periphery, and the rotary shaft 16 is replaced with the driven gear 11. The rotary blocks 22 each having a spiral groove 6 are attached, and the locking pin 21 is engaged with each spiral groove 6. In this way, as the lower end of the stopper portion 14 abuts on the turntable Q, the locking pin 21 descending together with the elevating rod 3 moves relative to the lower side from the upper end of the spiral groove 6, whereby the rotary block 22 itself is moved. All are rotated by 60 degrees in the same rotation direction, whereby the three plate holes 4 are horizontally rotated by 60 degrees and the rice P is retracted to form the plate holes S.
