DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cake cutting machine for cutting rice cake extruded from an extruder with a cutter.

[0002]

2. Description of the Related Art As the above-mentioned mochi-cutting machine, for example, the one shown in FIG. 12 is known. This mochi cutting machine includes an extruding mechanism 100 for extruding rice cake before cutting, and an extruding mechanism 100
And a cutting mechanism 110 for cutting the rice cake extruded from the rice cake. The extruding mechanism 100 includes an extruder 1 having a screw 102 therein for cutting the rice cake before cutting into the hopper 101.
It is configured to extrude from the nozzle 104 at 03. On the other hand, as shown in FIG. 13, the cutting mechanism 110 has a cutter 112 whose base end is fixed to the rotation shaft 111,
While the cutter 112 is rotating, the extruder 10
The rice cake extruded from 3 before cutting is cut.

[0003]

However, in the case of the conventional mochi-cutting machine, since the cutter 112 rotates, the falling position of the mochi after cutting varies depending on how the cutter 112 is cut. In some cases, it was difficult to drop it at a certain position. In addition, because of the quality of the product, the cut end of the rice cake is desired to be dropped on a conveying means such as a turntable, for example, but the cut end of the rice cake may be upward or sideways depending on the cutting condition of the cutter 112 as described above. And the quality was degraded.

[0004] Further, even when the extruding of the rice cake by the extruder 103 was completed, a phenomenon that some rice cake adhered and stayed in the nozzle 104 of the extruder 103 was confirmed. That is, in the case of the conventional nozzle 104, it was impossible to completely extrude all the rice cakes. Therefore, when the color of the rice cake is changed from white to red or vice versa, the rice cake of the previous color remains inside the nozzle 104 of the extruder 103, and the rice cake of the next color is replaced with the previous rice cake. There is a problem that colors are mixed and many defective products are generated after the color change.

An object of the present invention is to solve such a problem of the prior art, and an object of the present invention is to provide a rice cake cutting machine which can drop a cut rice cake at a predetermined position. Another object is to provide a rice cake cutter that can completely extrude all of the rice cake inside the extruder.

[0006]

SUMMARY OF THE INVENTION According to the present invention, there is provided a mochi-cutting machine comprising: an extruder for extruding mochi before cutting from a nozzle; a cutter for cutting the mochi extruded from a nozzle of the extruder; And a cutter driving means for driving, the cutter driving means being based on a first support shaft.
An end-supported first crank; and a first crank of the first crank.
A proximal end is connected to the second support shaft at the distal end, and the cutter is attached to the distal end.
A second crank on which the rotor is mounted, a rotating plate,
Between the outer periphery of the plate and the middle of the second crank in the longitudinal direction.
A connecting member to be connected, and by rotation of the rotating plate,
The cutter passes in front of the nozzle and during the passage the cutter moves in a direction substantially parallel to the blade of the cutter, thereby achieving the above object.

[0007]

[0008]

The rice cake cutting machine according to the present invention is arranged such that the cutter driving means moves the cutter in front of the nozzle of the extruder in a direction substantially parallel to the blade of the cutter during the passage of the cutter. Drive. Thereby, the cutter cuts the rice cake extruded from the nozzle by an operation obtained by adding an operation of pulling and cutting to an operation of cutting by pressing. For this reason, the rice cake is reliably cut at the point where the operation of pulling and cutting is added. In addition, since the cutter driving means is constituted by a crank mechanism having two or more cranks, and the cutter is attached to one of the cranks, the crank mechanism moves near the bottom dead center of the cutter trajectory to the speed up to that point. Can be designed to slow down rapidly. For this reason, even if the cutting condition of the cutter is poor, it is possible to drop the cut rice cake at a fixed position almost directly below the nozzle.

In addition, the rice cake is rotated and falls by the pushing and cutting operation acting on the rice cake at the time of the cutting. At this time, assuming that the falling distance is a predetermined value, the rice cake can be received on a turntable or the like with the cut portion of the rice cake facing downward.

On the other hand, when a nozzle having a shape in which the inside of the nozzle becomes narrower in the vicinity of the extruding port so as not to cause stagnation of the mochi and the mochi passage is used, the mochi is formed inside the extruder. All rice cakes can be discharged from the extruder without stagnation.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below.

FIG. 1 is a front view showing a rice cake cutting machine (excluding a cutting mechanism) according to the present embodiment, and FIG. 2 is a front view showing a cutting mechanism of the rice cake cutting machine according to the present embodiment. This rice cake cutting machine includes an extrusion mechanism 1 for extruding rice cake before cutting, and a cutting mechanism 10 for cutting the rice cake extruded from the extrusion mechanism 1. The extruding mechanism 1 is configured to extrude the rice cake before being cut into the hopper 4 from the nozzle 3 by an extruder 2 having a screw therein.

On the other hand, as shown in FIG. 2, the cutting mechanism 10 includes a first crank 12 having a base end fixed to a first support shaft 11 and a second support 12 at a distal end of the first crank 12. A second crank 14 having a base end supported by a shaft 13 and a cutter 20 for cutting rice cake at a distal end thereof, and a rotating shaft 16 which rotates in one direction by receiving a force from a motor (not shown).
A rotating plate 18 coaxially fixed to the
Cutter driving means including a connecting member 19 for connecting a portion near the outer periphery of the rotating plate 18 and the middle of the second crank 14 is provided. As shown in FIG. 3, the connecting member 19 has a configuration in which a bolt and a nut have a flat spring 19a between the rotary plate 18 and the second crank 14.

The operation of the cutter driving means is as follows. When the rotating plate 18 rotates around the rotating shaft 16 by receiving the force from the rotating shaft 16, the intermediate portion of the second crank 14 rotates via the connecting member 19. At this time, the base end side of the second crank 14 is
Through the first crank 12, and further connected to the first crank 12.
Since the base end side of the crank 12 is connected to the first support shaft 11, the cutter 20 is, as shown in FIG.
Move on the locus that is repeated in the steps of →→→→→→. In the middle of this trajectory, the cutter 20 crosses the front of the nozzle 3 of the extruder 2 with a predetermined clearance.

FIGS. 5 to 10 are exploded views of each step of FIG. 3 for easy understanding. FIG.
-1 indicates a step between and -1 in FIG.
Indicates a step between and, -2 indicates a step between and -3, and -3 indicates a step between and -2.

Here, the moving locus of the cutter 20 is shown in FIG.
As shown in (2), when traversing the front of the nozzle 3, the cutter 20 is gradually moving in the horizontal direction during a period from approaching the upper side of the nozzle 3 to passing from the lower side.

Therefore, the cutter 20 moving along such a locus cuts the rice cake before cutting extruded from the extruder 2. At this time, it is natural that the cutter 20 moves the rice cake before cutting from the upper side to the lower side.
Moves toward the rotating shaft 11 side. Therefore,
Unlike the conventional case in which the cutter simply rotates in a circular motion, the cutter has a function of moving like a pull, so that it is possible to surely cut the rice cake. In addition, since the cutter 20 cuts the rice cake from the upper side to the lower side as described above, the position where the rice cake falls can be made constant regardless of the cutting condition of the cutter 20. Further, when the rice cake is cut by the cutter 20, the force of the moving cutter 20 acts on the rice cake, and a rotational force acts on the cut rice cake. Therefore, by adjusting the height of the turntable (not shown) provided below the nozzle 3, it is possible to drop the rice cake on the turntable with the cut end of the rice cake always down.

Further, the locus passes through the bottom dead center when one of the two substantially arc-shaped curves changes from one to the other. That is, after descending rapidly from top to bottom, it stops once and then rises. Therefore, since the cutter 20 stops after the rapid decrease, the cutting quality of the cutter 20 is poor, and the rice cake attached to the cutter 20 is shaken off. Also at this time, the moving direction of the cutter 20
Does not greatly differ from the cutting direction, and can be easily dropped on the turntable.

FIG. 11A is a longitudinal sectional view of a nozzle 3 provided in the extruder 2 constituting the rice cake cutting machine of the present embodiment,
(B) is a longitudinal sectional view showing the conventional nozzle 104. The conventional nozzle 104 has an inner surface formed so as to have a constant thickness with respect to the outer surface, and has an internal shape in which the inner diameter rapidly increases from the extrusion opening 104a to the inner part. On the other hand, the nozzle 3 of this embodiment has an inner shape formed so that the inner diameter gradually increases from the extrusion port 3a to the inner part, and has a thick portion 3b near the extrusion port 3a. .

In this embodiment, the inner shape of the nozzle 3 is set as described above because the extruder 2 is not provided unless the thick portion 3b is provided.
This is because the mochi pushed out by the stagnation stays in that part. That is, in the conventional nozzle without the thick portion 3b, the mochi stays. On the other hand, in the case of the nozzle 3 of the present embodiment, cake does not stay in the nozzle. In addition, the internal shape of the nozzle 3 in the present embodiment is based on the outer surface of the rice cake remaining in the nozzle 3 at the time when all of the rice cake before cutting cut into the hopper 4 is extruded by the extruder 2. I have decided. However, the inner shape of the nozzle 3 does not need to completely match the outer surface of the remaining rice cake as described above, but the inner surface of the nozzle 3 is located inside the outer surface of the remaining rice cake. Preferably, it is in a state.

Therefore, in the case of the nozzle 3 having such a configuration, even if the color of the rice cake is changed from white to red, or vice versa, the previous color is mixed into the rice cake of the next color. The occurrence of defective products after color change can be prevented.
Further, there is an advantage that the work efficiency can be improved without the need to remove the rice cake of the previous color from the inside of the nozzle, and the rice cake can be cut continuously. In addition, the above is
The same applies not only to the case where the color of the mochi is white and red, but also to other colors, and furthermore to the mochi using other materials. For example, a case in which a white rice cake and a rice cake are exchanged is applicable.

In the above embodiment, a crank mechanism having two cranks is used as the cutter driving means. However, the present invention is not limited to this, and a clang mechanism having three or more cranks may be used.

[0023]

As described above in detail, in the case of the present invention, the cutter driven by the cutter driving means cuts the rice cake extruded from the nozzle by the operation of adding the operation of pulling and cutting. Therefore, the rice cake can be reliably cut. In addition, if the crank mechanism is designed so that the speed near the bottom dead center of the cutter trajectory is suddenly reduced from the speed up to that point, the cut rice cake will fall almost directly below the nozzle even if the cutter is not sharp enough. It is possible to do.

In addition, since the rice cake falls while rotating, due to the pushing and cutting operation acting on the rice cake at the time of the cutting, the cut portion of the rice cake faces downward when the falling distance is a predetermined value. It is possible to receive it on a turntable or the like while it is in the position.

On the other hand, if a nozzle having a shape in which the inside of the nozzle becomes narrower in the vicinity of the extrusion port so as not to cause the retention of the rice cake and the rice cake passage is used, the rice cake is formed inside the extruder. All rice cakes can be discharged from the extruder without stagnation.
