Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cake cutting device for cutting a rice cake in a vertical direction while intermittently feeding a stick-shaped rice cake on a belt conveyor.

[0002]

2. Description of the Related Art Conventionally, this kind of rice cake cutting apparatus is disclosed, for example, in Japanese Patent Application Laid-Open No. 9-65842 (A23Ll / 10). This rice cake cutting device is provided with a belt conveyor that intermittently moves a stick-shaped rice cake, and a cutting blade that operates in a vertical direction is provided at the front of the belt conveyor. The rice cake holding device is provided in the rice cake pressing device when the belt conveyor is stopped, and rice cakes placed in a plurality of rows at predetermined intervals on the belt conveyor are pressed against the belt conveyor by rice cake pressing rollers having substantially the same width as the belt conveyor, and the rice cake and the belt are pressed. Sliding between conveyors was prevented.

[0003] In a state where the rod-shaped rice cake is moved by a predetermined distance on the belt conveyor and stopped, the vicinity of the cut portion of the rice cake is pressed by a plurality of small-diameter pressing rollers which are reciprocated in the longitudinal direction of the rod-shaped rice cake. The rod was cut by a predetermined dimension from one end of the stick-shaped rice cake by dropping the blade. In this case, if the cut rice cake and the cut rice cake are not surely cut, each of the cut rice cakes will continue in uncut portions. For this reason, the cutting blade is slightly bitten into the belt conveyor so that the cut mochi does not connect with the mochi.

[0004] When setting the thickness of the cut rice cake,
The intermittent feed amount of the belt conveyor has been adjusted by shifting the position of the eccentric cam fixed to the rice cake cutting device with a bolt. The intermittent feed amount of the belt conveyor determines the moving amount of the rice cake placed on the belt conveyor, and thereby determines the thickness of the rice cake to be cut. When determining the thickness of this mochi, the thickness of one piece of mochi was determined by the average value of the measured thicknesses of a plurality of cut mochi.

[0005]

However, while the bar-shaped rice cake to be cut to a predetermined thickness is moved by the belt conveyor and the bar-shaped rice cake is cut on the belt conveyor, if the belt conveyor is thin, the cutting blade is cut. As a result, the belt conveyor is cut to a certain extent so that the belt conveyor can be used for a predetermined period of time even if the rod-shaped rice cake is cut. For this reason, the belt conveyor becomes heavy, and if the cutting blade cuts and breaks by cutting the rice cake for a predetermined period of time, it can not be lifted and replaced alone, and if the belt conveyor is heavy, maintenance is easy. There was a problem that could not be performed.

Further, when cutting a stick-shaped rice cake on a belt conveyor, a plurality of small-diameter pressing rollers are used to hold the vicinity of the cut portion of the rice cake, and then the cutting blade is lowered to cut the rice cake. No stopper was provided on the plurality of pressing rollers. When the bar-shaped rice cake is shortened by cutting,
The small-diameter holding roller holding the shortened rice cake rotates. For this reason, the shortened rice cake will collapse,
There is a problem that the rice cake cannot be cut to a predetermined thickness, and rice cakes resulting from poor cutting are wasted.

A plurality of rows of bar-shaped rice cakes are placed on a belt conveyor, and a plurality of bar-shaped rice cakes are provided so as to be orthogonal to each other in the longitudinal direction of the bar-shaped rice cakes. The vicinity of the cut portions of the rice cakes in a plurality of rows on the conveyor was pressed. As a result, the rod-shaped rice cake was cut into a predetermined thickness, but the rod-shaped rice cakes placed in a plurality of rows on the belt conveyor were not all the same thickness. For this reason, a thick stick-shaped rice cake can be reliably pressed by the rice cake pressing roller, but a thin stick-shaped rice cake cannot be reliably pressed because the rice cake pressing roller floats, and the rod-shaped rice cake is cut at the time of cutting. There is a problem that the rear end portion may fall down.

Further, when setting the thickness of the rice cake to be cut,
After adjusting the eccentric cam, a plurality of cut rice cakes were measured, and the average value was calculated to determine the thickness of one rice cake. For this reason, there has been a problem that setting the thickness of the rice cake to be cut is complicated and takes a lot of trouble.

The present invention has been made in order to solve the problems of the prior art, and can surely cut a plurality of rod-shaped rice cakes having different thicknesses at a constant thickness. It is an object of the present invention to provide a rice cake cutting device capable of easily and easily setting the thickness dimension of rice cake.

[0010]

That is, the rice cake cutting device according to the first aspect of the present invention comprises a first belt conveyor for intermittently feeding a rod-shaped rice cake, and the first belt conveyor when the first belt conveyor is stopped. A cutting blade that cuts the rice cake vertically in the forward direction of the belt conveyor, a first rice cake presser that presses the rice cake against the first belt conveyor and prevents the first belt conveyor and the rice cake from slipping, A second belt conveyor that is continuously provided on the rear side with respect to the traveling direction of the first belt conveyor and constantly moves, and a rice cake placed on the second belt conveyor is pressed by the second belt conveyor. And a second mochi holding device to be attached.

According to a second aspect of the present invention, in addition to the above, the first rice cake pressing device comprises a roller support member, and a large diameter rice cake holder rotatably attached to the roller support member. A roller and a small-diameter rice cake press roller which is located on the side of the first belt conveyor in the traveling direction from the large-diameter rice cake press roller and is rotatably attached to the roller support member;
It is provided with an interlocking belt stretched between these two rollers and interlocking the two rollers, and an air cylinder for pushing down the roller support member in a direction of the first belt conveyor so as to be able to be separated and brought into contact therewith.

Further, the rice cake cutting device according to the third aspect of the present invention is the same as the first or second aspect, wherein the first rice cake pressing device is
A plurality of the first belt conveyors are arranged side by side in the width direction.

Further, the rice cake cutting device according to the invention of claim 4 is the same as claim 1, 2 or 3, and further comprises a servomotor for driving the first belt conveyor and a cutting device for vertically moving the cutting blade. A blade driving device, a control device for controlling the servomotor and the cutting blade driving device, and a numerical input device for inputting numerical data relating to the thickness of the rice cake to the control device. Based on the numerical data input in step (1), the distance by which the first belt conveyor is moved by the servomotor during the cutting operation by the cutting blade is determined.

The control device 35 has a numerical value input device 36.
The numerical value input device 36 is configured to input numerical value data relating to the thickness of the rice cake 40. The control device 35 controls the rotation of the servomotor 14 to move the first belt conveyor 11 by a predetermined amount based on the numerical data input by the numerical input device 36, and the first belt conveyor 11 stops. In this state, the cutting blade driving device 34 is controlled to cut the rice cake 40 with the cutting blade 32. When cutting the rice cake 40, the cutting blade 32
Is made to bite into the first belt conveyor 11 so that even a somewhat soft rice cake 40 can be reliably cut.

The control device 35 is configured to move the first belt conveyor 11 by a size corresponding to the numerical value of the numerical data input by the numerical value input device 36.
That is, based on the numerical data input by the numerical value input device 36, the control device 35 sets the first belt conveyor 11 by the servo motor 14 after the cutting operation by the cutting blade 32 is completed. It is configured to be moved.

The numerals input by the numerical value input device 36 correspond to the movement amount of the first belt conveyor 11, and the first belt conveyor 11 moves by the numerical size input by the numerical value input device 36. It is configured to be. The numbers that can be input with the numerical value input device 36 can be input from 0.1 to 99.9, and numbers from 1 to 99 are usually used. In such a case, if the number input by the numerical value input device 36 is 5.0, the first belt conveyor 11 moves 5.0 mm by the drive of the servo motor 14 and

In addition, the thickness of the minute amount of rice cake 40 below the decimal point can be adjusted by the number below the decimal point so that the thickness variation in the drying process after cutting can be adjusted due to the variation in the moisture content of the raw material of the rice cake 40 and the variation in the moisture content during the production of the rice cake 40. It is configured to be adjustable.

That is, the first belt conveyor 11 moves by the number of the numerical data input by the numerical value input device 36, and the amount of the movement becomes the thickness of the cut rice cake 40. 40 thickness up to 100m
It can be cut to a thickness of from 0.1 m to a minimum of 0.1 mm.
The thickness of the actual rice cake is preferably about 1.5 mm to 5.0 mm.

On the second belt conveyor 18, a second mochi holding device 31 is provided. The second mochi pressing devices 31 are provided at the rear of the first mochi pressing devices 22 at a predetermined distance from each other. In this case, the second rice cake pressing device 31 is provided above the vicinity of the roller 19C around which the second belt conveyor 18 is stretched. The second mochi-holding device 31 is provided with a mochi-holding roller 31A having a diameter larger than that of the large-diameter mochi-holding roller 27.
The rice cake 40 is configured to be securely pressed down on the second belt conveyor 18 without slipping.

Next, the operation of the rice cake cutting apparatus 10 having the above configuration will be described. The rice cake 40 has a width of about 90 mm and a thickness of about 40.
mm (semi-elliptical upper side), about 900 in length
mm. In addition, rice cake 40
Is pressed against the first belt conveyor 11 by the first mochi holding device 22 and the second mochi holding device 3
1 is pressed against the second belt conveyor 18. The cutting blade 32 is configured to move up and down at a position substantially in contact with the small diameter rice cake pressing roller 29 (FIG. 8).

First, when the rice cake cutting device 10 operates, the second belt conveyor 18 is moved by the rotation of the motor 21. In this case, the rice cake 40 on the second belt conveyor 18 is moved by the second rice cake pressing device 31 to the second belt conveyor 1.
8 and the first belt conveyor 11
The rear end of the upper rice cake 40 is the rice cake 4 on the second belt conveyor 18.
It is always pushed at the tip of 0 and adheres closely.

Each rice cake 40 placed on the first belt conveyor 11 is pressed against the first belt conveyor 11 by the first rice cake pressing device 22. In this case, as shown in FIG. 6 and FIG. 7, even when there is a thick rice cake 40H or a thin rice cake 40L, since the first rice cake pressing device 22 is provided corresponding to each rice cake 40, the first belt conveyor is provided. The thick mochi 40H or the thin mochi 40L placed in parallel on the plurality 11 are surely pressed against the first belt conveyor 11.

The control device 35 drives the servomotor 14 to intermittently move the first belt conveyor 11 based on the numerical data of the numerical data input by the numerical input device 36. Then, in a state where the first belt conveyor 11 is stopped by the intermittent movement, the control device 35 controls the cutting blade driving device 34 to lower the cutting blade 32 to cut the rice cake 40, and then raise the cutting blade 32 ( 9 and 10).

At this time, the control device 35 lowers the cutting blade 32 before the first belt conveyor 11 stops. That is, the cutting edge 32 is 20 mm to 30 m on the upper surface of the rice cake 40.
m, the first belt conveyor 11 is stopped. Further, the control device 35 operates the first belt conveyor 11 before the cutting blade 32 moves up to the uppermost end. That is, the cutting edge 32 is 20 mm to 3 mm above the upper surface of the rice cake 40.
The first belt conveyor 11 is moved at the time when the distance is 0 mm. Thereby, the waste of the cutting speed of the rice cake 40 due to the movement of the cutting blade 32 outside the cutting range is reduced.

If one piece of the mochi 40 (in this case, a plurality of pieces is acceptable), the thickness of the mochi 40 is measured, and if it matches the set dimensions, the cutting of the mochi 40 is continued. . When the measured thickness of the rice cake 40 is thinner or thicker than the set dimension, the lower one digit (in this case, the number after the decimal point) of the numerical value input device 36 is adjusted to set the thickness of the rice cake 40 within the set dimension. Put in.

The first belt conveyor 11 intermittently moves to intermittently feed the rice cake 40, and the second belt conveyor 1
8 is constantly moving, so the first belt conveyor 11
When the first rice cake 40 is placed on the top, and the next rice cake 40 is placed on the second belt conveyor 18, the rear end of the first rice cake 40 and the front end of the next rice cake 40 are brought into close contact with a predetermined pressure without any gap. You. When the rice cake 40 is cut, the first rice cake pressing device 22 is provided with a small-diameter rice cake pressing roller 29 on the cutting blade 32 side, and the small-diameter rice cake pressing roller 29 and the large-diameter rice cake pressing rollers 27, 28 are provided. An interlock belt 30 is stretched.

When the end of the rice cake 40 placed first is cut, the tip of the next rice cake 40 is cut. In this case, when approaching the vicinity of the end of the first rice cake 40, the rice cake 4
0 is thin and easy to fall, but the first mochi holding device 2
Since the rice cake 40 is pressed against the small diameter rice cake pressing roller 29 provided in 2, the rice cake 40 can be cut without falling down even in the vicinity of the end of the rice cake 40 (FIG. 11).

That is, since the large diameter rice cake pressing rollers 27 and 28 press the next rice cake 40, the small diameter rice cake pressing roller 29 is fixed without rotating. In this case, since the interlocking belt 30 is stretched between the large diameter rice cake pressing rollers 27, 28 and the small diameter rice cake pressing roller 29, the large diameter rice cake pressing rollers 27, 28, which cannot fix and rotate the rice cake 40, are fixed by the small diameter rice cake pressing roller. 29 is fixed. This allows
The small-diameter rice cake pressing roller 29 rotates near the end of the rice cake 40, so that the rice cake 40 is securely pressed down without falling down, and the cutting failure due to the rice cake 40 falling down can be minimized.

Further, by cutting the rice cake 40, the rice cake 40 on the second belt conveyor 18 moves to the first belt conveyor 11 side, and the rice cake 40 is placed on the second belt conveyor 18. Since there is a space available, the next rice cake 40 is newly placed there. In this case, if a new rice cake 40 is placed substantially in contact with the rear end of the rice cake 40 placed first, the rice cake 40 placed on the second belt conveyor 18 will be placed on the first belt conveyor 11. It is possible to continuously cut the rice cake 40 into a predetermined thickness, and this is repeated.

As described above, the first belt conveyor 11 for intermittently feeding the rod-shaped rice cake 40, and when the first belt conveyor 11 is stopped, the rice cake 40 is moved up and down at the front of the first belt conveyor 11 in the traveling direction. A cutting blade 32 for cutting in the direction is provided. Further, a first rice cake holding device 22 for pressing the rice cake 40 against the first belt conveyor 11 to prevent slippage between the first belt conveyor 11 and the rice cake 40 is provided, and in the traveling direction of the first belt conveyor 11. On the other hand, a second belt conveyor 18 that constantly moves to the rear side is connected.

Also, since there is provided a second rice cake pressing device 31 for pressing the rice cake 40 placed on the second belt conveyor 18 against the second belt conveyor 18, the rice cake 40 is placed on the second belt conveyor 18. Can be always pressed against the rice cake 40 on the first belt conveyor 11. That is, since the second belt conveyor 18 is connected to the first belt conveyor 11, the first belt conveyor 11 can be shortened, thereby reducing the weight of the first belt conveyor 11. Becomes possible.

The large-diameter mochi pressing rollers 27, 28 are rotatably mounted on the roller support member 24 of the second mochi pressing device 31.
A small-sized rice cake pressing roller 29 is rotatably mounted on the roller support member 24 at a position closer to the traveling direction of the first belt conveyor 11 than the large-diameter rice cake pressing rollers 27 and 28. And these large diameter rice cake holding roller 2
7, 28, and an air cylinder 23 that stretches the interlocking belt 30 across the small-diameter rice cake pressing roller 29 and presses down the roller support member 24 in a direction of the first belt conveyor 11 so that the roller cylinder 24 can be freely separated and contacted. Stretched interlocking belt 3
With 0, the large-diameter mochi pressing rollers 27 and 28 and the small-diameter mochi pressing roller 29 can be rotated in conjunction with each other.

Thus, even if the rice cake 40 on the first belt conveyor 11 is pressed by the small-diameter rice cake pressing roller 29 by lowering the air cylinder 23, the small-diameter rice cake pressing roller 29
Can be prevented from rotating, and the stick-shaped rice cake 40 can be cut by cutting.
Is shorter, the rice cake 40 on the first belt conveyor 11 can be securely fixed by the small-diameter rice cake pressing roller 29, and the cut and shortened rice cake 40 can be prevented from falling down.

Further, a plurality of first rice cake pressing devices 22 are juxtaposed in the width direction of the first belt conveyor 11, and a plurality of rows of rod-like rice cakes 40 placed on the first belt conveyor 11 are provided. Can be made to correspond to the rice cake pressing devices 22 respectively. Thereby, it becomes possible to press each bar-shaped rice cake 40 on the first belt conveyor 11 alone by each first rice cake pressing device 22, and the thick bar-shaped rice cake 40 and the thin bar-shaped rice cake 40 are formed. Even when mixed, the mochi holding device hits the thick rod-shaped mochi 40 as in the past,
The inconvenience that the thin stick-shaped rice cake 40 cannot be pressed can be prevented.

Further, a servo motor 14 for driving the first belt conveyor 11 and a cutting blade driving device 34 for vertically moving the cutting blade 32 are provided, and a control device 35 for controlling the servo motor 14 and the cutting blade driving device 34 is provided. Provided. Further, since the control device 35 is provided with a numerical value input device 36 for inputting numerical value data relating to the thickness of the rice cake 40, the control device 35 uses the numerical data input by the numerical value input device 36 to cut the cutting blade 32. , The distance by which the first belt conveyor 11 is moved by the servo motor 14 during the cutting operation can be determined. If the numerical value input by the numerical value input device 36 is made to correspond to the thickness of the rice cake 40 to be cut, the numerical value input device 36 simply inputs the number that becomes the thickness of the rice cake 40 to obtain a predetermined thickness. Can be cut.

On the other hand, FIGS. 12 and 13 show another rice cake pressing device 37. The rice cake pressing device 37 is a roller 3 having a width capable of pressing two rows of rice cakes 40 placed on the second belt conveyor 18 to universal joints 38A, 38A attached to a pair of cylinders 38, 38.
9 is attached. In this case, the roller 39 is configured to be able to move up and down on one side with respect to one side by the universal joint 38. That is, the roller 39 is configured by the universal joint 38 so that the roller 39 can be moved toward or away from the second belt conveyor 18 on the other side with respect to the second belt conveyor 18 in parallel or on one side.

A small-diameter mochi pressing roller which is positioned on the side of the first belt conveyor in the traveling direction of the large-diameter mochi pressing roller and is rotatably attached to a roller support member; Since it has an interlocking belt that interlocks the rollers and an air cylinder that pushes down the roller support member in a detachable manner in the direction of the first belt conveyor, the interlocking belt that is stretched makes the large-diameter mochi pressing roller and the small-diameter mochi pressing roller possible. Can be rotated in conjunction with each other. Accordingly, even if the rice cake on the first belt conveyor is pressed by the small diameter rice cake pressing roller by the lowering of the air cylinder, the rotation of the small diameter rice cake pressing roller can be prevented. Therefore, even when the bar-shaped rice cake is shortened by cutting, the small-diameter rice cake pressing roller can be securely fixed to the large-diameter rice cake pressing roller by the interlocking belt, and the convenience of the rice cake cutting device can be greatly improved. It is something that will be.

In particular, since the small-diameter mochi pressing roller is securely fixed to the large-diameter mochi pressing roller by the interlocking belt, short mochi can be surely pressed without falling down. Thereby, even if the rod-shaped rice cake is shortened by the cutting, the rod-shaped rice cake can be cut to a substantially predetermined size to the end without falling down. Therefore, it is possible to prevent a problem that the rice cake is cut to a size other than the predetermined size, and it is possible to reduce waste caused by poor cutting of the rice cake, thereby increasing the practical effect of the rice cake cutting device.

According to the invention of claim 3, according to claim 1,
Alternatively, in addition to the second aspect, the first mochi holding device is arranged in a plurality in the width direction of the first belt conveyor, so that a plurality of rows of rod-shaped mochi and the first mochi are placed on the belt conveyor. It is possible to make the pressing devices correspond to each other. This makes it possible for each of the first rice cake pressing devices to independently press the respective bar-shaped rice cakes on the belt conveyor. Therefore, even if a plurality of rows of bar-shaped rice cakes are placed on the belt conveyor, if there is a thick bar-shaped rice cake and a thin bar-shaped rice cake, the mochi holding device hits the thick bar-shaped rice cake as in the related art and becomes thin. It is possible to reliably prevent the inconvenience that the stick-shaped rice cake is not pressed down.

According to a fourth aspect of the present invention, in addition to the first, second, or third aspect, a servo motor for driving the first belt conveyor and a cutting blade drive for vertically moving the cutting blade. Device, a control device for controlling these servomotors and the cutting blade driving device, and a numerical input device for inputting numerical data relating to the thickness of the rice cake to the control device, wherein the control device is a numerical input device. Based on the input numerical data, since the distance to move the first belt conveyor by the servo motor during the cutting operation by the cutting blade is determined, for example, a numerical value input by a numerical value input device,
If the thickness of the rice cake to be cut is made to correspond, it is possible to cut the rice cake to a predetermined thickness simply by inputting a number which is the thickness of the rice cake with the numerical value input device. As a result, the troublesome work of measuring the thickness after cutting the rice cake as in the related art can be omitted. Therefore, since the thickness of the rice cake to be cut can be easily input, the operation rate of the rice cake cutting device is also improved, and the profit can be significantly improved.
