2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 52-96479 discloses a fixed lower blade for cutting a steel plate and an arc-shaped upper blade mounted on an upper blade base that swings by rotation of a crankshaft. The fulcrum for guiding the upper knives provided on the upper knives is connected to the shear frame via a connecting rod, and the position of the fulcrum is selected to be a portion corresponding to the central portion in the longitudinal direction of the upper blades, and is also connected. There is described a rolling cut type shearing machine capable of cutting while rolling the upper blade with a simple mechanism by rolling the rod substantially parallel to the longitudinal direction of the upper blade without slipping on the steel plate.

Japanese Unexamined Patent Publication No. 1-264712 discloses a hoop member provided with a fixed blade, a moving blade which comes in contact with and separates from the fixed blade, a ram for mounting the moving blade, and an eccentric drive means for driving the ram. In the cutter, a hoop material cutter is described which is provided with a means for converting into the sliding motion of the ram, withstands a heavy load with little wear damage, and is capable of high-speed and high-load without vibration during high-speed operation. .

In Japanese Unexamined Patent Publication No. 10-309620, moving cutting blades and fixed cutting blades are arranged on one side and multiple sides of a corrugated fin conveying path, and the moving cutting blade is guided by guide means to the conveying path. In a corrugated fin cutting device which is movably guided in a direction orthogonal to each other, one end of a link member is connected to the moving cutting blade, and the other end of the link member is connected to a rotating member rotated by a drive motor. By doing so, a corrugated fin cutting device is described, which is simple and small in size, but can significantly reduce the cutting time as compared with the prior art.

On the other hand, when the object to be cut is a food log, for example, a ham log, a slicing device for producing sliced ham, bacon, etc. has been well known. These slicing devices are disclosed in JP-A-5-50394 and JP-A-10-
As described in Japanese Patent No. 29195, etc., 1-2 m
Using the columnar ham log, the ham log is supplied to the rotating disk blade, which is equipped with a disk blade that sequentially cuts from the tip to produce sliced ham, etc. Since the disc blade is moved while revolving, and is cut by rotation, the disc blade has a wide moving range but a narrow cutting range, and there is a problem in cutting efficiency.

[0006]

Recently, automation and speeding up have been attempted in the manufacturing process of sliced ham and the like in which raw wood-like solid food is sliced. Especially, in the automatic weight control process and the automatic alignment process, the product is automatically controlled and speeded up by devising the conveyor of the transportation means, but the speed of the slicing device is already 25 sheets / sec. The practical limit has been reached, and if the speed is further increased, there is a problem in that not only the spoilage rate of slices further increases, but also non-standard products that are nonstandard in weight and the like occur.

An object of the present invention is to provide a wide range of cutting, which is small in a compact movement, has a wide range of cutting efficiency, is excellent in cutting efficiency, has a small resistance at the time of cutting, has less tissue damage at the cutting site, and controls cutting. Accordingly, it is an object of the present invention to provide a cutting device capable of half-cutting a cutting object such as a food log without leaving it and making a cut on the surface of the cutting object.

[0008]

[Means for Solving the Problems] The inventors of the present invention have been improving and improving the ham slicer from the past, and have come to the conclusion that all the problems of the current ham slicer cannot be solved individually. , All functions and performance required in ham slice equipment, such as productivity improvement such as high-speed production and automation, device miniaturization and cost reduction, yield improvement, diversified consumer needs including visual and taste We worked on the development of a device that can meet all of the above requirements again and simultaneously and comprehensively, and can handle multiple ham logs with different lengths, such as individual weight control, individual thickness control, individual number of ham logs. A food log slicing device capable of slicing simultaneously while controlling individually such as control has already been developed (Japanese Patent Laid-Open No. 2000-2888983).

This food log slicing device is a ham slice device capable of simultaneously slicing three ham logs having different lengths while individually controlling, for example, individual weight control, individual thickness control, and individual number control. Yes, the problem of the conventional slicing device, that is, in order to match the speeding up packaging machine or conveyor, when trying to speed up the slicing process, from the damage of the slice due to the high speed slicing and the predetermined weight range. It can be said that it is an extremely excellent slicing device that solved the problem of yield reduction such as the occurrence of out-of-specification products, but the cutting unit itself is
The rotating shaft of the disc-shaped cutting blade is rotatably supported on one side of the cutting blade mounting rotary member with a predetermined distance from the axis, and is revolved while rotating the disc blade using the drive means. The conventional structure of slicing ham logs was thus adopted.

The present inventors have earnestly studied a slicing device capable of slicing three ham logs at the same time and at high speed while individually controlling three ham logs, and a linear long blade is used for slicing at the same time and at a high speed. We reached the conclusion that it was indispensable, and worked on the development of a slicing device with the basic concept of adopting a straight long blade. When cutting with a straight long blade at the same time, the cutting resistance increases as seen in press cutting, and when cutting at high speed, cutting characteristics such as tissue damage at the cutting site became a problem. Then, by chance,
Long blade movement similar to that of a kitchen knife used by a kitchen knife to cut sashimi, thick wraps, and other foods that tend to break during cutting, that is, the long blade is pushed down and pulled toward you to change the speed at which the blades move vertically and horizontally. It was thought that three ham logs could be sliced simultaneously and at high speed without tissue damage at the cut site. And
After much trial and error, in order to embody such a long blade movement in a concrete slicing device, a straight line is formed between a pair of rotating members arranged at a predetermined interval that rotate on the same plane. The present invention has been completed by discovering that it is sufficient to connect with a long blade.

That is, according to the present invention, a pair of rotating members arranged at a predetermined interval so as to rotate in the same direction on the same plane, and rotate substantially on the same plane as the plane on which the pair of rotating members rotate. The cutting device according to claim 1, further comprising a connecting blade for connecting between the rotating members, and the connecting blade is an elongated quadrangular connecting blade.

BEST MODE FOR CARRYING OUT THE INVENTION As a cutting device of the present invention, a set of rotating members arranged at predetermined intervals for rotating in the same direction on the same plane, and a plane on which the set of rotating members rotate. Half-cut or full-cut (cutting) with a connecting blade that connects rotating members that rotate on substantially the same plane
It is not particularly limited as long as it is a cutting device that can be performed, the shape of the connecting blade is not particularly limited, such as a long rectangular shape, a long rectangular shape such as a trapezoid, and a square shape where only the cutting edge has an arc shape, but a linear cutting edge. A linear long blade made of a plate-shaped elongated rectangle having a can be preferably exemplified. The length of the connecting blade is not particularly limited as long as it is longer than the width of the object to be cut in the width direction, but normally, it is substantially equal to or greater than the distance (length) between the rotation centers of the pair of rotating members. Also, a slightly long length can be preferably exemplified. The thickness of the connecting blade may vary depending on the physical properties of the object to be cut, but the thickness of the cutting blade normally used for the object to be cut can be adopted. The plane on which the set of rotating members rotates and the plane on which the connecting blades rotate are displaced in parallel by the thickness of the connecting blades. Therefore, the above-mentioned "rotating on substantially the same plane as the plane on which the pair of rotating members rotates" means that the plane on which the pair of rotating members rotates and the plane displaced in parallel by the thickness of the connecting blade are It means to rotate.

The rotating member may be any disc-shaped rotating body that is rotatably supported by a rotating shaft that is rotatably driven by a known driving means such as a motor, and is on the same plane. Examples of the pair of rotating members arranged at a predetermined interval for rotating with a pair of rotating members having a radius of the same length, and a pair of rotating members having slightly different radii. The pair of rotating members are usually arranged to rotate in synchronism, ie at the same rotational speed, but in some cases they can also rotate at different speeds. In order to rotate in synchronization, two drive sources capable of rotating in synchronization may be used, but it is also possible to use a sprocket and a chain or the like to use one of the rotation shafts as a drive shaft and the other as a driven shaft. it can. The rotation speed of the rotating member is 200 to 1200 rpm, preferably 400 to 10 rpm.
00 rpm can be illustrated. The interval between the pair of rotating members is larger than the sum of their radii, and is not particularly limited as long as it is an interval at which a cutting object can be cut by the connecting blade, and the diameter of the rotating member is, for example, When the cutting object is a ham log having a diameter of 9 to 10 cm, it is preferably set to 3 to 4 times that.

A connecting blade is attached to the rotating member to connect the rotating members. Different types of cutting devices can be used depending on the connection state between the rotating members. Hereinafter, various aspects of the cutting device of the present invention will be described with reference to the drawings. In addition, a ham log is illustrated as an object to be cut in the drawings. In the figure, 1 and 1'are a pair of rotary members, 2 are rotary shafts, 3 are connecting blades, 4 are bearing parts, 5 are loose parts, 6 are loose grooves, 7 are free pins, and M is ham log. , S represents the support lane.

In FIG. 1, an elongated rectangular connecting blade 3 is provided at the same position in the vicinity of the outer edges of the pair of rotating members 1 and 1'which rotate in synchronization with each other. The cutting device according to the invention is pivotally mounted in the bearing part 4 parallel to the line connecting 2).
Further, FIG. 2 shows a state in which the connecting blade 3 of the cutting device shown in FIG. 1 makes one rotation from the initial position and returns to the initial position again with time. Ham log M
The case where the sliced ham is manufactured by cutting the slices will be described below with this basic type of cutting device.
The cutting device shown in FIG. 1 has a pair of rotating members 1 and 1'having a diameter approximately four times the diameter of the ham log M, and the cutting edge is located on the surface of the support lane S at the lowermost position of the cutting edge. Since the lower ends are in contact with each other, when the rotary members 1, 1 ′ rotate 270 degrees from the initial position, the cutting edge contacts the ham log M. When this contact is made, the blade edge moves only in the vertical direction and does not move in the horizontal direction. Next, from the initial stage of cutting to the middle stage of cutting of the ham log M, the cutting edge of the connecting blade 3 descends while drawing an arc, while the moving speed of the cutting edge is greater than the lateral speed in the vertical direction, In the middle cutting period, the vertical and horizontal velocities become equal,
Even from the middle stage of cutting to the latter stage of cutting, the blade edge of the connecting blade 3 descends while drawing an arc, and during that time, the moving speed of the blade edge becomes faster than the vertical speed in the horizontal direction, and the moving direction of the blade edge at the completion of cutting is There is no movement in the vertical direction only in the horizontal direction. Thus, by cutting while changing the moving speed of the cutting edge in the vertical direction and the horizontal direction, it is possible to slice three ham logs at the same time and at high speed without damaging the tissue at the cutting site.

The cutting object to which the cutting apparatus of the present invention can be applied is not particularly limited, and in addition to the above-mentioned ham logs, various food materials such as vegetables, fish, cheese, baked dough, noodle dough and the like, thick rolls, etc. The following foods can be preferably exemplified. Then, as described above, when the cutting device of the basic type shown in FIG. 1 is used, the moving direction near the lower limit position of the cutting edge of the connecting blade 3 is exclusively the horizontal direction, and the vertical movement is almost eliminated. Therefore, at the lowest position of the cutting edge, the initial setting is performed so that the surface of the support lane S of the cutting target object and the lowermost edge of the cutting edge have a predetermined distance, so that a half cut is left with a predetermined distance. It becomes possible to do. For example, if the initial setting is made so that there is a slight gap between the surface of the support lane S and the lowermost edge of the cutting edge, it is possible to even cut with one piece of fish skin left. On the contrary, if the initial setting is made so that the bottom edge of the cutting edge is located slightly below the surface of the cutting object such as konjac that is placed on the support lane S and has a constant height, the cutting object such as konjac Countless cuts can be made on the surface of an object at high speed. Therefore,
For the sake of convenience, the cutting method of the food or food material of the present invention includes not only half-cutting but also cutting.

FIGS. 3 and 4 show another embodiment of the cutting device of the present invention. In the cutting device of the present invention shown in FIG. 3, the elongated rectangular connecting blade 3 has its spine at the same position from the outer edges of the pair of rotating members 1 and 1 ′ that rotate synchronously, a little from the center. It is rotatably supported at the supporting portion 4 in parallel with a straight line connecting the rotation centers of the pair of rotating members 1, 1 ′ so that the cutting edge intersects the straight line connecting the rotation centers of the pair of rotating members. The cutting operation and operation by this type of cutting device are basically the same as those of the above-mentioned basic type cutting device, but the physical properties of the cutting object are soft, and the movement speed of the cutting edge in the horizontal direction is larger than that in the vertical direction from the beginning of cutting. It can be particularly advantageously used when desired, when making a cut into a cutting object having an inclined surface, or when changing the depth of the cut into the cutting object depending on the site.

In the cutting device of the present invention shown in FIG. 4, a long and narrow rectangular connecting blade 3 connects the rotation centers of the pair of rotating members near the outer edges of the pair of rotating members 1 and 1'which rotate synchronously. One rotating member 1 so that it intersects with a straight line (in FIG. 4, slightly upwards at the initial position).
Is rotatably supported at a bearing portion 4 and is loosely attached to the other rotary member 1'at a loosening portion 5. As shown in FIG. 5, the loose attachment to the rotating member 1'is performed by vertically fixing the rotating member 1'to the idle groove 6 provided at one end of the connecting blade 3. This is performed by loosely fitting the pin 7, but there is no particular limitation as long as it is a known loosening means. According to this type of cutting device, when the pair of rotating members 1, 1 ′ start to rotate synchronously, the distance between the bearing portion 4 and the standing fixing position of the free-wearing pin 7 changes, and the change in the change occurs. The length of the play groove 6 is set so as to be substantially the same as or slightly longer than the width. The cutting operation and operation by this type of cutting device are basically the same as those of the above-mentioned basic type cutting device, but the physical properties of the cutting object are soft, and the speed of movement of the cutting edge in the horizontal direction is larger than that in the vertical direction from the beginning of cutting. It can be particularly advantageously used when desired, when making a cut into a cutting object having an inclined surface, or when changing the depth of the cut into the cutting object depending on the site.

As a cutting device of the present invention in another aspect, although not shown, a pair of elongated rectangular connecting blades are provided in the vicinity of the outer edges of a pair of rotating members having different radii that rotate in synchronization. A cutting device that is rotatably supported by one rotating member and is loosely attached to the other rotating member so as to intersect with a straight line connecting the rotation centers of the rotating members, or a pair of rotating devices that rotate at different rotational speeds. In the vicinity of the outer edge of the rotating member (or one rotating member that rotates at a constant speed and the other rotating member that rotates at a momentarily variable speed), in parallel with the straight line connecting the rotation centers of the pair of rotating members, One example is a cutting device that is rotatably supported by one rotating member (a rotating member that rotates at a constant speed) and is loosely attached to the other rotating member (a rotating member that rotates at an instantaneously variable speed). it can.
