DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cake cutting apparatus for cutting a rice cake in a vertical direction while intermittently feeding it with a conveyor belt.

[0002]

2. Description of the Related Art Conventionally, there has been a cutting device for intermittently feeding a stick-shaped rice cake with a conveyor belt and cutting the rice cake vertically in a front portion of the conveyor when the belt is stopped. Correspondingly, a rice cake holding device is provided to prevent slippage between the rice cake and the conveyor belt so that the rice cake has a certain thickness.

[0003] The above-mentioned rice cake pressing device is configured such that a roller formed by winding a sponge around one metal shaft is placed on the upper surface of the rice cake and pulled downward by a tension spring.

Therefore, if the stick-shaped rice cake has a certain height, the rice cake is pressed against the conveyor belt with a constant pressure, and slippage between the rice cake and the conveyor belt can be avoided.

[0005] However, since the upper surface of the actually manufactured rice cake is uneven and its height is not constant, the tension of the tension spring of the above rice cake holding roller changes, and the rice cake and the conveyor belt are changed. The pressure contact force with the pressure is not constant. Therefore, when the pressing force between the cake and the conveyor belt is small (when the roller is at a position where the height of the cake is low)
In this case, slippage occurs between the rice cake and the belt, and the thickness of the rice cake becomes larger than desired. In other words, the conventional cutting device has a problem that the thickness of the rice cake varies.

In recent years, in this type of industry, there has been a demand for the development of a rice cake cutting apparatus capable of cutting a rice cake with a constant thickness even if the height of the rice cake is not constant.

[0007]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a rice cake cutting apparatus which can cut a rice cake with a constant thickness even if the height of the rice cake is not constant.

[0008]

The present invention relates to a stick-shaped rice cake M
Conveyor 1 that intermittently feeds, cutting blade 2 that cuts the cake M vertically in front of the belt conveyor 1 when the belt is stopped, and presses the cake M against the conveyor belt 10 to prevent slippage between them. A rice cake cutting device comprising a rice cake pressing device 3, wherein the rice cake pressing device 3 is mounted on a roller support arm 30 swingably supported above the belt conveyor 1 and at one end of the roller support arm 30. Rotatingly mounted rice cake holding roller 31
And an air cylinder 32 that pushes down the roller support arm 30.

It is desirable that the forward part of the conveyor belt 10 is received by a number of carrier rollers 11 below the forward part.

When air at a constant pressure is supplied to the air cylinder 32, the roller support arm 30 is pushed down with a constant force regardless of the length of the output shaft of the air cylinder 32. Therefore, even if the height of the stick-shaped rice cake M is not constant, the rice cake M can be kept at a constant force by the rice cake pressing roller 31.
To the conveyor belt 10. As a result, slippage between the cake M and the conveyor belt 10 can be eliminated, and the cake can be cut to a certain thickness.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

This rice cake cutting device has four lines. Each line is, as shown in FIG. 1, a belt conveyor 1 for intermittently feeding a rod-shaped rice cake M, and a front portion of the belt conveyor 1 when the belt is stopped. A cutting blade 2 for cutting the rice cake M in the vertical direction, a rice cake pressing device 3 for pressing the rice cake M against the conveyor belt 10 to prevent slippage therebetween, and a rice cake holder for pressing the rice cake M near the cutting blade 2 And an apparatus 4.

[0013] As shown in FIG.
The conveyor belt 10 having a loop shape is rotated by driving a motor, and the forward path portion of the conveyor belt 10 is received by a number of carrier rollers 11 below the conveyor belt 10. In this apparatus, a so-called cam clutch is used to intermittently feed the conveyor belt 10 by the thickness of the cut rice cake. Here, the means for intermittently feeding the conveyor belt 10 may not be mechanical but may electrically control the rotation of the motor.

As the conveyor belt 10, a belt having a V-shaped projection on the back side of both edges is used. On the other hand, a pulley having a V-shaped cross section is used as a pulley constituting the conveyor. Then, the conveyor belt 10 is stretched between a pair of pulleys in such a manner that the protrusions are fitted into the concave portions. Therefore, meandering of the conveyor belt 10 is prevented.

As shown in FIG. 1, the cutting blade 2 has a blade formed at the lower end, and can be moved up and down by a mechanism shown in FIG.

2, reference numeral 20 denotes a motor, reference numerals 21 to 26 denote power transmission sprockets, reference numeral 27 denotes a crank, reference numeral 28 denotes a crank arm, and reference numeral 29 denotes a guide frame. The power is transmitted as the vertical motion of the cutting blade 2 through the path of the power transmission sprocket 21 → the power transmission sprocket 22 to 26 → the crank 27 → the crank arm 28.

As shown in FIG. 1, the cake holding device 3 includes a roller support arm 30 swingably supported above the belt conveyor 1 and the roller support arm 30.
Holding roller 31 rotatably attached to one end of the
A ring body 33 slidably mounted on the roller support arm 30; and an air cylinder 32 for pushing down the roller support arm 30 through the ring body 33. The shaft end and the ring body 33 are connected so as to be rotatably supported. In FIG. 1, the roller support arm 30
In addition, the air cylinder 32 is supported by a support member f that is erected and fixed to the gantry F.

As shown in FIG. 1, the rice cake pressing device 4 includes an upper and lower support member 41 attached to the guide frame 29 and a bar member 42 attached to the support members 41, 41 so as to be vertically movable. A roller support 45 fixed to the lower end of the rod 42 and having four small-diameter pressing rollers 43 and 44; and a compression coil spring 46 for urging the roller support 45 downward. I have. In this apparatus 4, four small-diameter pressing rollers 4 are provided.
The rice cake M is pressed by 3, 44 in order to press the rice cake M as close as possible to the cutting position.

Here, in this rice cake cutting device, when the belt conveyor 1 is in a driving state, the cutting blade 2 is raised to a non-cutting position of the rice cake M, and when the belt conveyor 1 is in a stopped state, the cutting blade 2 is not moved. It has descended to the cutting position of the cake M.

Since the rice cake cutting device has the above-described structure, even if the upper surface of the stick-shaped rice cake M has irregularities, the rice cake M is cut one after another at a constant thickness in four lines.

[0021]

According to the contents of the operation described in the section of the means for solving the problems, it is possible to provide a rice cake cutting apparatus which can cut a rice cake with a constant thickness even if the height of the rice cake is not constant. Was.
