[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cake cutting machine that cuts rice cake into edible size.

[0002]

2. Description of the Related Art Conventionally, in a rice cake cutting device according to Japanese Patent No. 2741357, as shown in the drawing of the same publication, a stretched rice cake M placed on a belt conveyor 1 is pressed from above by a rice cake pressing roller 31. While being conveyed, it is intermittently conveyed by the set distance and sequentially cut by the cutting blade 2.

[0003]

In general, since the rice cake M is sprinkled with powder, slippage is likely to occur between the conveyor belt 10 and the rice cake M even though the rice cake pressing roller 31 is provided. . Because of the slippage, the intermittent conveying distance of the rice cake M tends to vary, so the rice cake M
It becomes difficult to keep the cutting size constant.

An object of the present invention is to make it easier to keep the cut size of rice cake constant.

It is in the holding position for pressing 2.

When the drive motor 29 of the pushing and driving mechanism 28 is driven from the initial state of the cutting, the contact plate 26 of the pushing and feeding body 24 is moved in the conveying direction XF by the set distance as shown in FIG. 4B. Move intermittently. With the intermittent movement, each feeding stop position R between the feeding standby position P and the feeding movement end position Q.
Then, the rice cake 32 is pressed by the flexible pressing roller 15a, and the cutting blade 13 reaches the cutting completion position while being supported by the pressing body 14a, and the rice cake 32 is sequentially cut from the transport head 33 side. After that, as shown in FIG. 4B, the contact plate 26 of the pushing body 24 is moved to the pushing movement end position Q.
At this point, the conveyance tail portion 34 of the rice cake 32 is removed from the detection position by the sensor (not shown), and the contact plate 26 of the pushing body 24 returns from the pushing movement end position Q to the pushing standby position P. Next, when both of the stoppers 4 and 5 are moved from the conveyance blocking position to the conveyance allowing position, the intermediate rice cake 32 is conveyed from the intermediate conveyor 2b to the terminal side conveyor 2c, and the trailing rice cake 32 is started. It is conveyed from the side conveyance section 2a toward the intermediate conveyance section 2b. During the transportation, the intermediate rice cake 32 pushes up the contact plate 26 of the pushing body 24 from the pushable position D to the non-pushable position U, and then the preceding rice cake 3 at the trailing end side transport unit 2c.
The operation is stopped as 2, and the cutting is in the initial state. Further, in this initial cutting state, the succeeding spread rice cake 32 comes into contact with the stopper 4 which has returned to the transport blocking position and stops as the intermediate spread rice cake 32 at the intermediate transport section 2b. The next mochi rice cake 32 is placed on the leading end side transport unit 2a as a succeeding mochi rice cake 32. This operation is repeated and the mochi rice cake 32 is continuously cut.
