FIG. 5 is a sectional view of a plate-shaped cooked rice cutting mechanism.
[0009]
As shown in FIGS. 1 and 3, between a pair of front and rear frames 1 and 2, a pair of cooked rice compression / intermittent transfer mechanisms 3 and 4 are vertically arranged so as to be opposed to each other at a constant interval a in the left-right direction. It is allowed.
Of the pair of intermittent rice transfer and compression mechanisms 3 and 4, one of the mechanisms 4 is rotatably fixed to the frames 1 and 2, but the other mechanism 3 is disposed outside the frames 1 and 2. By pivotally supporting the upper end portion on the side surface, it is pivotally supported by a pair of rotating plates 5 arranged so as to be rotatable in the left-right direction, that is, in a direction contacting / separating from one mechanism 4. Can be adjusted arbitrarily.
[0010]
In the embodiment shown in the drawings, the pair of intermittent rice transfer mechanisms 3 and 4 that serve as a combination of cooked rice are provided with a total of three rollers 3 a, 3 b, 3 c, 4 a, 4 b, 4 c from the top to the bottom. An array is formed at regular intervals. In addition to this, an endless belt (not shown) can be wound around two rollers (not shown) that are pivotally supported on the upper and lower parts.
[0011]
In the illustrated embodiment, one of the cooked rice compression / intermittent transfer mechanism 4 rotates three rollers 4a, 4b, and 4c in total, large, medium, and small, to frames 1 and 2 by roller shafts 4d, 4e, and 4f. The shaft is freely fixed and formed.
The other rice-compression-compressing intermittent transfer mechanism 3 fixes the uppermost large roller 3a and the upper end of the rotating plate 5 to the frames 1 and 2 by a roller shaft 3d so as to be rotatable. The intermediate roller 3b and the roller 3c having a small lower end are formed by inserting into a long hole (not shown) penetrating the frames 1 and 2 and rotatably supporting the rotating plate 5 with a shaft.
[0012]
Further, the interval a between the pair of cooked rice compression / intermittent transfer mechanisms 3 and 4 is formed so that the upper part is widened and gradually becomes narrower as it comes to the lower end. As shown in FIG. The cooked rice b fed from the cooked rice hopper 6 to the upper portion of the interval a by the conveyer belt 7 is gradually compressed by a pair of counter-rotating pairs of cooked rice intermittent transfer mechanisms 3 and 4 and formed downward in a plate shape. It is transferred to.
[0013]
As shown in FIG. 4, pulleys 8, 9, 10, 11, 12, and 13 are fixed to the roller shafts 3d, 3e, 3f, 4d, 4e, and 4f described above. Motors 15 and 16 are fixed to the frame 14, pulleys 17 and 18 are fixed to the respective shafts 15a and 16a, pulleys 17 fixed to one motor shaft 15a, and idlers to the pulleys 8, 9, 11, and 12 described above. A drive belt 20 is wound around a pulley and a tension pulley 19.
A drive belt 23 is wound around pulleys 10 and 13 fixed to the lowermost roller shafts 3f and 4f and a pulley 18 fixed to the other motor shaft 16a via idler pulleys 21 and 21 and a tension pulley 22. is there.
As a result, the rollers 3a, 3b, 3c, 4a, 4b, 4c are opposed to each other at the same rotational speed by the motors 15, 16.
[0014]
As shown in FIGS. 1 and 4, the intermediate portion of the swing arm 24 is placed on the outer surface of the frames 1 and 2 by a support shaft 25 such as a bolt or a step screw, and the horizontal direction indicated by the arrow in FIG. The lower end of the rotary plate 5 is pivotally connected to the lower end of the rotary plate 5 by a link 26, and is horizontal to a screw hole (not shown) formed through the upper end. The feed screw rod 27 is screwed so as to be able to advance and retract.
[0015]
As shown in FIG. 3, the upper end portion of the swing arm 24 is bifurcated and both lengths are formed so as to be opposed to each other in the length direction of the swing arm 24. By inserting the short shafts 28a and 28b that project symmetrically from both ends of the rotary block 28 into the holes 24c and 24d, the rotary block 28 is rotatably supported between the branch plates 24a and 24b. The screw hole 29 of the feed screw rod 27 is formed to penetrate in the diameter direction of the rotary block 28.
[0016]
Accordingly, when the feed screw rod 27 is rotated forward and backward at a fixed position, the upper end portion and the lower end portion of the swing arm 24 are rotationally displaced symmetrically about the support shaft 25, thereby via the link 26. In FIG. 1, the rotating plate 5 is rotated about the roller shaft 3d leftward or rightward in FIG. 1, and moves one of the cooked rice compression / intermittent transfer mechanism 3 in the left-right direction, and the other cooked rice compression / intermittent transfer mechanism 4 The interval at the lower end of the can be arbitrarily adjusted to the small interval a ₁ or the large interval a ₂ .
[0017]
Next, the control mechanism 30 for adjusting the above-described distance a will be described.
As shown in FIGS. 1, 2, and 4, the motor 31 that is started by operating a thick-winding pushbutton switch and a thin-winding pushbutton switch (not shown) is installed in the housing 31 fixed to the frame 14. 32, a reversible motor 33, and a sensor 34 are fixedly mounted, and the above-described feed screw rod 27 is rotatably supported.
[0018]
As shown in FIG. 2, a signal cam 35 having steps 35 a and 35 b provided at intervals of 180 ° is fixed to the shaft 32 a of the motor 32. The steps 35 a and 35 b are detected by the sensor 34. It is configured to
Further, the shaft 33a of the reversible motor 33 and the feed screw rod 27 are linked to each other by a gear transmission mechanism 36, and a dial 37 is fixed to the reversible motor shaft 33a as shown in FIG. .
[0019]
According to the control mechanism 30, when a thick winding pushbutton switch (not shown) is turned ON, the motor 32 is started, the signal cam 35 is rotated, the sensor 34 is detected, and the detection signal is reversible via an inverter (not shown). The rotation direction and rotation speed of the motor 33 are controlled. As a result, the feed screw rod 27 is rotated a predetermined number of times in a predetermined method, so that one of the cooked rice compression / intermittent transfer mechanism 3 is moved from the position shown by the solid line in FIG. 1 is moved to the left and stopped at the position indicated by a two-dot chain line in FIG. 1, and the small interval a ₁ is adjusted to the large interval a ₂ . Accordingly, the cooked rice b is formed into a thick plate-shaped cooked rice for thick winding.
[0020]
Further, when a thin winding push button switch (not shown) is turned on, it operates in the opposite direction to adjust the small winding small interval a ₁ .
[0021]
FIG. 5 illustrates the cutting mechanism 38. A shutter 38c is disposed between the shutter guides 38a and 38b so as to be movable forward and backward, and the plate-shaped cooked rice b ₁ is cut into a fixed amount (length) by the shutter 38c. A certain amount of cooked rice is supplied onto the laver winding forming mechanism 40 shown in FIG.
[0022]
【The invention's effect】
Since the present invention is configured as described above, it is set in advance so that the plate-shaped cooked rice is formed in a thickness for thick winding or thin winding, and the switching is performed by a switch operation. By doing so, the thickness of the plate-shaped cooked rice can be switched easily and easily and accurately without any erroneous operation, so that the fixed-sized cooked rice having a desired thickness can be stably supplied to the next step.
