[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a food cutting shutter device that cuts a rod-shaped food that is covered with an inner packaging material such as a bean paste by a skin material such as bread dough, and more specifically, a plurality of shutter pieces provided in the shutter device. The present invention relates to a food cutting shutter device that can accurately perform the synchronous rotation.
[0002]
[Prior art]
As a prior example according to the present invention, there is, for example, Japanese Patent No. 2754178. In the preceding example, an enclosed space centered on the center position is formed on four rotation shafts arranged at equal intervals on the same circumference centered on a predetermined center position, and passes through the enclosed space. Provided with a plurality of shutter pieces for cutting food, and pivotally connecting the tip and one end of a lever provided in a motor provided to open and close the surrounding space by rotating each shutter piece. 1 link and the eccentric portion of the first and second rotating shafts are pivotally connected, and the eccentric portion of the second rotating shaft and the third rotating shaft are pivotally connected to the second link, and The eccentric part of the third rotating shaft and the eccentric part of the fourth rotating shaft are pivotally connected to the third link.
[0003]
[Problems to be solved by the invention]
In the conventional configuration as described above, the lever of the motor and the first link are pivotally connected, and the first link and the eccentric portions of the first and second rotating shafts are pivotally connected. Further, since the second, third, and fourth rotating shafts are interlocked and connected via the second and third links, the first, second, and third links are connected to the first, second, and second links. In this configuration, the rotation is sequentially transmitted via a pivotal connection portion with the eccentric portion of the third and fourth rotating shafts.
[0004]
Therefore, if a slight clearance occurs in the pivot connecting portion between each link and each rotation shaft, the clearance is accumulated, and it becomes difficult to rotate the four shutter pieces in synchronization with each other. Occasionally, a slight gap is created between any shutter pieces, and a portion of the food may leak out as dough residue from this gap and may remain attached to the shutter pieces. Furthermore, in individual shutter pieces, there is a problem that excessive contact pressure is generated at the contact portion and local wear may occur. The above-described problems are important in reliably operating each shutter mechanism in a configuration in which a plurality of shutter mechanisms including a plurality of shutter pieces are synchronized and interlocked.
[0005]
By the way, for example, gears can be provided on four rotating shafts, and the gears can be meshed with ring-shaped internal gears to rotate the four rotating shafts synchronously. When the backlash between the internal gears is large, the same problem may occur, and further improvement is desired.
[0006]
[Means for Solving the Problems]
The present invention has been made in view of the conventional problems as described above, and the invention according to claim 1 includes three or more rotating shafts arranged at equal intervals on the same circumference centered on a predetermined center position. A shutter piece is provided on one end side of the rotary shaft, and a shutter piece capable of cutting food passing through the surrounding space is formed at an eccentric position on the other end side of each rotary shaft. In the food cutting shutter device configured to open and close the surrounding space by rotating the rotating shafts through the engaging portions and rotating the shutter pieces, the rotating shafts. Each of the engaging portions is engaged with an engaged portion provided on a common rotating link member that rotates eccentrically while always maintaining a constant direction to rotate each rotating shaft.
[0007]
According to a second aspect of the present invention, in the food cutting shutter device according to the first aspect, each of the shutter pieces is formed in a symmetric shape about each rotation axis.
[0008]
According to a third aspect of the present invention, in the food cutting shutter device according to the second aspect, the shutter device includes a plurality of adjacent shutter mechanisms, and the shutter piece positioned between the adjacent shutter mechanisms is adjacent to the shutter. This is a configuration shared by the mechanism.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2, the shutter device 1 according to the present embodiment forms a hollow portion 9 by separating the first plate 3 and the second plate 5 by a separation member 7 such as a column or a side plate. The box-shaped casing 11 is provided. A sub-plate 13 is provided on the outer surface side (the lower surface side in FIG. 1) of the second plate 5, and the second plate 5 and the sub-plate 13 are provided with a plurality of rotating shafts 15, 17, 19,. 21, 23, 25, 27 are rotatably supported.
[0010]
The rotating shafts 15, 17, 19, and 21 are arranged at equal intervals on the same circumference centered on a predetermined center position P1, and the rotating shafts 15, 23, 25, and 27 are Centering on the axial center, it arrange | positions at equal intervals on the same periphery centering on the said center position P1 and the center position P2 of a symmetrical position. Shutter pieces 15A, 17A, 19A, 21A, 23A, 25A, and 27A are integrally attached to outer end portions of the rotary shafts 15, 17, 19, 21, 23, 25, 27, and 29, respectively. .
[0011]
Each of the shutter pieces 15A,... 27A has the same shape and is formed in a symmetrical shape with the rotation shafts 15,. The plurality of shutter pieces 15A, 17A, 19A and 21A constitute one shutter mechanism 29A, and the plurality of shutter pieces 15A, 23A, 25A and 27A constitute another adjacent shutter mechanism 29B. The shutter piece 15A located between the shutter mechanisms 29A and 29B is shared by the adjacent shutter mechanisms 29A and 29B.
[0012]
The shutter pieces 15A, 17A, 19A, and 21A in the shutter mechanism 29A rotate in synchronization with the direction of arrow A, so that the distal ends of the shutter pieces 15A, 17A, 19A, and 21A are at the center position P1. The adjacent shutter pieces 15A, 17A, 19A, and 21A are always in contact with each other from the contacted state (the state shown in FIG. 2), and the space surrounding the center position P1 is gradually enlarged.
[0013]
When the rotation in the direction of the arrow A continues, the opposite portions of the shutter pieces 15A, 17A, 19A, and 21A that have been in contact with each other come into contact with each other, and the surrounding space that surrounds the central position P1 is gradually reduced. When the shutter pieces 15A, 17A, 19A, and 21A are reversed (rotated 180 °), the surrounding space is closed as shown in FIG. 2, and is in the same state as the initial state.
[0014]
That is, when the shutter pieces 15A, 17A, 19A, and 21A are rotated in the direction of the arrow A in synchronization, the opening and closing of the surrounding space that surrounds the central position P1 is repeated. Therefore, the food that passes through the surrounding space is cut by opening and closing the shutter pieces 15A, 17A, 19A, and 21A.
[0015]
In addition, when opening and closing the enclosed space surrounded by the plurality of shutter pieces 15A, 17A, 19A, and 21A that are in contact with each other, each shutter piece is replaced with a case where the shutter pieces 15A, 17A, 19A, and 21A are rotated synchronously. A configuration in which 15A, 17A, 19A, and 21A are synchronized to repeat reciprocating rotation may be used.
[0016]
Each of the shutter pieces 15A, 23A, 25A, and 27A in the shutter mechanism 29B having the shutter pieces 15A, 23A, 25A, and 27A is simultaneously rotated or reciprocated synchronously, and the shutter mechanism 29B has the center position P2. The enclosed Go space is opened and closed simultaneously, and the food that passes through the Go space is simultaneously cut.
[0017]
Each of the first and second plates 3 and 5 is formed with a hole (not shown) through which food passing through the surrounding space can pass.
[0018]
As described above, in order to simultaneously rotate or rotate the shutter pieces, the inner ends of the rotary shafts 15,... Each of the eccentric portions 31 is provided, and an engaging portion 33 such as a pin is provided at the same eccentric position in the same direction of each of the eccentric portions 31 of the rotary shafts 15. Each engaging portion 33 is rotatably engaged with each engaged portion 37 provided at a plurality of positions of a plate-like rotary link member 35 provided rotatably in the hollow portion 9 via a bearing or the like. Yes. The engaging portions 33 and the engaged portions 37 are engaged in a zero clearance state. The rotary link member 35 has a hole 35H through which food can pass.
[0019]
In order to keep the directionality of the rotary link member 35 constant at all times, the linear guides in the X direction (direction perpendicular to the paper surface in FIG. 1) are provided at a plurality of locations on the inner surface of the first plate 3. 39, and a plurality of sliders 41 are movably supported by the linear guide 39. Each slider 41 supports a linear guide 43 in the Y-axis direction provided on the rotary link member 35 so as to be movable in the Y-axis direction.
[0020]
Furthermore, a drive motor 45 such as a servo motor as an example of an actuator is mounted on the first plate 3, and a rotary shaft 47 of the drive motor 45 is connected to the rotary shafts 15, 17,. An eccentric piece 49 having an eccentric amount equal to the eccentric amount of each engaging portion 33 is integrally attached. The eccentric piece 49 is engaged with a cylindrical member 51 as an example of an engaged portion provided on one end side of the rotary link member 35 so as to be relatively rotatable in a zero clearance state via a bearing. is there.
[0021]
Accordingly, when the eccentric piece 49 is rotated by driving the drive motor 45, the rotary link member 35 is moved in the X-axis and Y-axis directions corresponding to the eccentric amount of the eccentric piece 49, and the rotary link member 35 has a directivity. It is always kept constant and rotated eccentrically.
[0022]
It should be noted that a parallelogram is formed by connecting the centers of adjacent rotating shafts (for example, 15 and 17) and the center of the eccentric portion 31, and the relationship between the rotating shafts and the rotating link members is a parallel link mechanism. It rotates while holding.
[0023]
When the rotation link member 35 is eccentrically rotated as described above, each rotation is caused by the engagement relationship between the engaged portion 37 of the rotation link member 35 and the engagement portion 33 provided on each of the rotation shafts 15, 17,. The shafts 15, 17, ... 27 are rotated synchronously in the same direction. Therefore, the shutter pieces 15A, 17A,... 27A provided on the rotary shafts 15, 17,... 27A are synchronously rotated to perform the opening / closing operation of the surrounding space as described above.
[0024]
In the above-described configuration, the rotating shafts 15,... 27 are synchronized and rotated simultaneously in the same direction by the common rotating link member 35. Therefore, the plurality of shutter pieces 15A,. Is something that can be done.
[0025]
Here, for example, even if a slight clearance is generated between the engaging portion 33 of one rotating shaft 17 and the engaged portion 37 of the rotating link member 35 and the synchronization tends to be slightly delayed, this clearance Does not affect the synchronous rotation of other rotating shafts, and the shutter pieces 15A, 17A, 19A, and 21A are in contact with each other in the shutter mechanism and are in a restricted state. Thus, the shutter pieces 15A, 17A, 19A, and 21A can be rotated synchronously.
[0026]
Further, as described above, since the synchronous rotation of the shutter pieces 15A,... 27A can be performed accurately, even if the shutter pieces 15A are shared by the adjacent shutter mechanisms 29A, 29B, any problem occurs. The shutter mechanisms 29A and 29B can be opened and closed synchronously.
[0027]
The present invention is not limited to the above-described embodiments, and can be implemented in other modes by making appropriate changes. That is, the shutter mechanism may be one instead of a plurality of rows. Further, the rotary link member is not necessarily limited to a plate shape, and may be an integral structure such as a cross-girder structure. Further, since the rotary link member is rotated by the parallel link mechanism, the linear guides in the X and Y directions can be omitted.
[0028]
【The invention's effect】
As can be understood from the above description, in the present invention, a plurality of rotating shafts are synchronously rotated by a common rotating link member to simultaneously open and close a plurality of shutter pieces. Even if a minute clearance is generated between the rotary shaft provided with the piece and the rotating link member, the minute clearance is not accumulated, and the conventional problems as described above can be solved. .
