In this embodiment, the lever 37, the engraving blade a, etc. are formed into an annular shape and are attached to the circular plate 12. There are eight of them, and the movable plate 8 is moved downward and upward by the rod 5 at a cycle of about 5 to 10 seconds. repeat.

In this embodiment, the following operations occur.

Due to the previous rise of the movable plate 8, the elevating shaft 9 and the flanged plate 21 rise to the highest point of elevation.After locking the donut-shaped plate 27 so that it cannot be lowered by the locking plate 31 and the support tube 34 (see Figure #1), As shown in FIG. 3, the lifting shaft 9 descends to near the lowest point of descent, and just before the engagement piece 35 of the support tube 34 is pushed down by the lever 420, the shaft 41 supported by the support surface 29 does not come down as shown in the figure. , roller 45 on the tsuba 20
Since only the blade 42 and 43 are lowered, the parallel links 42 and 43 are swung in the direction away from the lifting shaft 9 by the protruding piece 44 and the tension spring 43a, and the engraving blade a is moved to the operating opening point I above the outside of the sloping periphery of the plate base. shall be.

If the lifting shaft 9 continues to go down, the collar 20 of the flanged plate 21 hits the engaging part 35, and as shown in FIG. The lock plate 31 is pushed and made into an inclined shape as shown by the chain line in Fig. 4, and the lock is released. Therefore, the Dounara cedar plate 27 is lowered by the pongee 41 on which the bullet 38 is acting, and the weak spring 3
3, slide the lock plate 31 down on the guide shaft 22,
At the lowest point of descent of the lifting shaft 9, move the Dounara cedar board 27 a7 as shown in the figure.

A protrusion 44 and a roller 45 are parallel to the tension spring 43.
At the same time, the Lenoy 37 is also pushed down by the bullet R38, and the protruding piece 44 starts to be in a straight line with the lever 37 and hits the stopper 46. Due to one or more movements, the engraving blade a is pressed down to the sloped periphery of the dish dough. External carving starting point II
It swings and descends. Since the lever 37 contacts the supporting surface 29 of the Dounara cedar board 27 with the lever 41 at an angle that is in a straight line with the protruding piece 44 as shown in FIG. 8, it cannot be pushed down any further by the bullet 1fi38.

Subsequently, when the elevating shaft 9 begins to rise together with the movable plate 8, the roller 45 is lifted by the collar 20 of the flanged plate 21, and the protruding piece 44 swings together with the parallel links 42 and 43. On the other hand, the pressing of the engagement piece 35 by the collar 20 is released, but the locking of the donut-shaped plate 27 in the lowered position by the locking plate 31 is not released.

However, the roller 50 at the lower end of the parallel link 43 slides on the guiding piece 26 due to the elasticity of the bullet 38, and the roller 50 at the lower end of the parallel link 43
Since the rocking is returned as 5 rises, the pongee 41 is on the support surface 29
The engraving blade a carves C on the dish dough while floating slightly from the base, and the engraving blade a finishes the engraving and moves to the mount 1 [Ia (Fig. 9). At that time, the tsuba 20 hits the donut-shaped plate 27, Since the lock plate 31 is tilted as shown by the dashed line in FIG. 4 by turning the lock plate 3° to release the lock, the donut-shaped plate 27 follows the axis 41, and the engraving blade a reaches the second engraving end point (■). Move to Figure 10).

Subsequently, when the lifting shaft 9 reaches the uppermost point of elevation as shown in FIG. , the locking plate 31, which tends to release the lock as the donut-shaped plate 27 rises, returns to the horizontal position to produce the locking described at the beginning of this embodiment.

When the elevating shaft 9 moves from the uppermost point of elevation to the downward direction shown in FIG.
is moved to the activation point I.

(Already mentioned) In the engraving device in which the cam 16 equipped with the cam groove 52 illustrated in FIGS. 7A-C is mounted as shown in FIG.
, as the lifting shaft 9 and the flanged plate 21 move up and down, the contact pin 17 moves upward in the cam groove 52 and reversibly rotates the circular plate 12, especially from the engraving starting point (■) to the engraving ending point (■). When the engraving blade a moves (see Figure 8.9.10), the circular plate 12 and the engraving blade a rotate during the engraving operation of the engraving blade a caused by the lifting of the lifting shaft 9, resulting in the oblique angle shown in Figure 13B. When the circular plate 12 on which the shape is engraved does not rotate, the engraving becomes a straight line as shown in FIG. 13A.

In either case, since only eight sides of the plate cloth are engraved by the eight engraving blades a, the support plate 51 is rotated by a small angle together with the plate plate every time one engraving is completed. to arrange the sculptures in a circular direction.

(Function) The first method of the present invention is to move a plurality of engraving blades a from an operating opening point (2) at the upper part of the ring-shaped inclined circumferential surface of the dish dough.
Engraving starting point■, engraving ending point■, rising point■, operation opening point■
This creates a cyclical movement, and by simultaneously operating multiple engraving blades, engraves several places at the same time, which is not possible with manual engraving.

Further, the second invention device performs the first invention method by continuous lifting and lowering operations of the lifting shaft 9.

Further, in the third device of the present invention, the engraving blade is reversibly rotated by a cam device in conjunction with the vertical movement of the vertical axis, thereby changing the lateral shape of the engraving.

(Effects) The first method of the present invention is to simultaneously engrave multiple locations on the ring-shaped inclined surface of plate dough using a plurality of engraving blades. Since it follows the slope of the surface, it is possible to engrave very efficiently.

Furthermore, the second invention device has the effect of controlling the engraving operation by the engraving blade a of the first invention method.

Further, the third device of the invention has the effect of being able to perform deformed engraving based on the device of the second invention at the same speed as the $2 invention.
