Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rolled sushi cutting machine, and more particularly, a cutting machine capable of quickly cutting a bar-shaped rolled sushi rolled mechanically or manually into a bite-sized width and beautifully without losing its shape. It is about.
[0002]
[Prior art]
Conventionally, there are various apparatuses for automatically producing stick-shaped sushi rolls, and these apparatuses can be mass-produced. Such bar-shaped sushi rolls are cut into bite-sized widths when they are actually eaten. Therefore, at sites where sushi rolls are produced and sold, they are usually sold in a bite-sized width.
In this case, a lot of skill and craftsmanship are necessary to separate the stick-shaped roll sushi. If such a technique is insufficient, the seaweed portion may not cut well, and the rice and ingredients may be crushed. As a result, the shape is lost, the appearance is not only poor, but the texture is also deteriorated, and the commercial value is lowered.
Therefore, if an expert performs carving for stick-shaped sushi rolls, there should be no risk of the above-mentioned problems, but since it is a monotonous work, it is difficult to continue for a long time and the carving is unnatural due to fatigue. Or not in time for the production speed of stick-shaped roll sushi. Therefore, at the site where sushi rolls are manufactured and sold, there is a great demand for a cutting machine that can quickly and beautifully sort stick-shaped roll sushi.
In particular, in foreign countries with little familiarity with cooked rice, there is a strong demand for cutting machines such as those described above, because it is difficult to seek skilled people in carving and, in fact, the purchaser cannot perform carving well.
[0003]
Conventionally, as a sushi cutting machine, there are those described in Japanese Patent No. 2582317 and Japanese Patent Laid-Open No. 8-103233.
All of these conventional examples relate to the invention of the present inventor, and among these, the cutting machine described in Japanese Patent No. 2582317 has a direction parallel to the conveying direction of stick-shaped sushi such as pressed sushi on a conveyor. A single rotating blade that crosses the conveying direction at the confronting point of the conveyor, specifically, a rotating blade with a blade extending in a spiral shape, and gradually increasing the mouthful width from the end. It is something that is carved out.
In addition, the one described in JP-A-8-103233 first produces a long roll sushi which is a continuous body of stick-shaped roll sushi, and this long roll sushi is rotated in the same manner as described above. With a blade, it is cut into stick-shaped roll sushi that is about the length of one laver.
[0004]
[Problems to be solved by the invention]
As mentioned above, all conventional cutting machines cut sushi rolls or pressed sushi with a single rotary blade, but with a rotary blade to cut soft and easily squeezed items such as sushi rolls. There are not a few problems.
Because, in the cooking field, as you can see if you cut the fish fillet with a long knife like a willow blade knife and make it sashimi, you can cut a soft and easy-to-deform thing sharply, This is because it is considered that a cutting blade having a long blade portion is preferably cut or pushed by acting in one direction.
On the other hand, the rotary blade has a relatively short blade portion, and naturally there is a limit to lengthening the blade portion. In this way, if the rotary blade with a short blade part is applied in one direction to cut the sushi roll, the length of the blade part will be insufficient and the blade part will inevitably be pushed from the cut end of the sushi roll to the back. Therefore, there is a risk that the sharpness becomes worse and the cut end is not beautiful.
[0005]
In addition, as in the above-described conventional cutting machine, if the sushi roll is cut into a bite-sized width with a single rotary blade, the rotary blade will act on a single roll sushi many times. In the meantime, it takes a considerable amount of time, and quick carving is not easy, and when used together with a sushi roll manufacturing device, the speed of carving becomes a bottleneck and it is difficult to increase the overall production speed. is there.
Moreover, since the rotary blade acts many times on a single sushi roll, the blade tip of the rotary blade wears out early and the sharpness is lost, making it difficult to separate it beautifully, and it is often necessary to replace the blade. Therefore, it takes time for maintenance.
On the other hand, it is conceivable to increase the number of rotating blades and perform several cuttings at a time. However, if this is done, the resistance acting on the entire rotating blade is significantly increased and the load on the driving means is increased. Therefore, it is necessary to use a large and powerful drive means, which is not practical.
In view of the conventional problems as described above, the present invention can cut a stick-shaped rolled sushi swiftly and beautifully into a bite-sized width, and requires less maintenance such as blade replacement. An object is to provide a rolled sushi cutting machine.
[0006]
The present invention has been made in order to achieve the above-described object, and the roll sushi cutting machine according to claim 1 holds the stick-shaped roll sushi to be cut in a laterally horizontal posture toward the cutting position. The carry-in means for feeding this along a substantially arcuate path from high to low, and a small angle toward the carry-in means at a position intersecting the front portion of the feed path of this carry-in means, leaving a predetermined left and right interval. A plurality of vertically arranged cutting blades that descend in synchronization with the feeding operation of the carrying-in means, a carry-out conveyor that carries the rolled sushi cut behind the cutting blades in a substantially aligned state, and the carrying-in means And an intermittent rotation mechanism for intermittently rotating the loading rotary body, and a structure in which a gap is formed in the peripheral portion of the loading means so that the cutting blades can freely move in accordance with the arrangement interval of the cutting blades. It has become.
In the rolled sushi cutting machine according to claim 1, the carry-in means may be a belt conveyor having a required holding portion for rolled sushi on the belt surface, but in the rolled sushi cutting machine according to claim 2, the carrying-in means is The rotating body is formed by stacking a plurality of plate-shaped elements having substantially the same side shape and the same shape and size.
In the rolled sushi cutting machine according to claim 1 or 2, the cutting blade may be cantilevered. However, in the rolled sushi cutting machine according to claim 3, both ends of the cutting blade are fixedly attached to upper and lower frames. ing.
[0007]
[Action]
In the rolled sushi cutting machine according to claim 1, since the stick-shaped rolled sushi is fed in a lateral orientation by the loading means with respect to the plurality of cutting blades arranged on the left and right sides, The cutting blade will act at once, and the whole sushi roll will be cut into a bite-wide width at once.
In this case, while the rolled sushi is being fed, the slanted leading edge of the cutting blade in the forward tilted position first cuts into the rolled sushi to make a cut, and the blade of the cutting blade enters there to act on the rolled sushi for a long distance. Therefore, sushi rolls can be cut into pieces by cutting or pressing, just like cutting a sashimi with a long knife.
In addition, sushi rolls are moved along a substantially arc-shaped path, so that the cutting blades are pushed in while changing the rotation angle so that they roll, and the cutting blades act on a wide angular range of the outer periphery of the sushi rolls. . Therefore, the cutting blade cuts into the cross-section of the rolled sushi while concentrating the cutting force on one part of the outer periphery of the rolled sushi while changing the working angle to the rolled sushi.
In the rolled sushi cutting machine including the configuration according to claim 2, since the carrying-in means is a rotating body made up of a plurality of plate-shaped elements, the operation can be easily synchronized with the operation of the cutting blade. Besides, it is easy to disassemble and assemble.
In the rolled sushi cutting machine including the configuration according to claim 3, since both ends of the cutting blade are fixed to the upper and lower frames, it is possible to use a thin blade.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a rolled sushi cutting machine according to an embodiment of the present invention, and FIG. 2 is a partially broken front view of the rolled sushi cutting machine, and shows a state in which the upper cover is removed in any figure. ing. FIG. 3 is an enlarged side view of a part including a carry-in rotating body and a cutting blade which are the main parts of the rolled sushi cutting machine, (A) is a state when supplying rolled sushi, and (B) is a state during cutting. Respectively. FIG. 4 is an exploded perspective view of the carry-in rotating body and the cutting blade.
As shown in FIG. 1 and FIG. 2, the rolled sushi cutting machine according to the present embodiment is a rotating body (hereinafter referred to as a carry-in means) that feeds a bar-shaped rolled sushi to be cut to the cutting position at the upper part of the main body housing 1. (Referred to as a rotating body) 2, a plurality of vertically long cutting blades 3, and a carry-out conveyor 4. In addition to this, an upper cover 5 that covers the carry-in rotating body 2 and the cutting blade 3 is attached to the upper portion of the main body housing 1, but only the outer shape is indicated by a chain line in the drawing. The upper cover 5 is provided with a window hole on the carry-in side of the carry-in rotating body 2 and is opened on the carry-out conveyor 4 so that the carry-out surface is exposed.
[0009]
The main body housing 1 can be moved by a wheel 6 provided in the lower part, and includes a motor 7, a transmission shaft 9 for inputting the power of the motor 7 through the chain 8, and the transmission shaft 9 and the chain 10. An intermittent rotation mechanism 11 such as a Geneva Stove mechanism that is interlocked with each other is provided. A transmission case 12 that receives intermittent rotation output from the intermittent rotation mechanism 11 is attached to the upper side surface of the main body housing 1. From the upper end output side of the transmission case 12, the drive shaft 13 protrudes in a cantilevered manner above the main body housing 1, and the carry-in rotating body 2 is attached to the drive shaft 13.
[0010]
The carry-in rotating body 2 is a rotating body having a substantially star-shaped or windmill-shaped side surface, and receives the power of the motor 7 through the intermittent rotating mechanism 11, thereby counterclockwise in FIG. ) Intermittent rotation. Specifically, the intermittent rotation is a rotation that stops every 90 ° rotation. At four locations on the outer periphery of the carry-in rotating body 2, holding portions 14 each having a flat mounting surface along the tangential direction and a pressing surface rising from a position behind the rotation direction of this surface are formed. These holding portions 14 hold the stick-shaped rolled sushi in a horizontal and horizontal orientation with respect to the cutting blade 3, and with the rotation in the direction of arrow A, the rolled sushi is circled from a high level to a forward low level. The cutting blade 3 is fed along an arcuate path.
The entire carrying-in rotating body 2 may be integrally formed. However, in this embodiment, as shown in FIGS. 2 and 4, a plurality of plate-like element bodies 2a having the same shape and the same size are angled with respect to each other. By aligning and superimposing, it is a substantially star-shaped rotating body. And the clearance gap 15 is formed between the adjacent element bodies 2a in the outer peripheral part of each element body 2a. As will be described later, these gaps 15 are for allowing the cutting blade 3 to enter freely moving up and down.
[0011]
The cutting blade 3 is a vertically long blade having a linear blade portion, and a large number of blades are arranged in the horizontal direction at regular intervals and attached between the upper frame 16 and the lower frame 17; The left and right rods 16a of the upper frame 16 are inserted into a cylindrical slide guide 18 which is inclined and erected on the main body housing 1, thereby moving up and down in a posture inclined by a small angle θ toward the loading rotary body 2 side. It is supported freely. Here, as shown in FIG. 4, the arrangement interval p of the cutting blades 3 is set corresponding to the thickness q of each element body 2a of the carrying-in rotating body 2, and each cutting blade 3 is a carrying-in rotating body. It is possible to enter the gap 15 between the two element bodies 2a so as to freely move up and down. The cutting blade 3 intersects the front portion of the feeding path of the loading rotator 2 by causing the cutting blade 3 to enter the clearance 15 on the outer periphery of the loading rotator 2 in the forward direction of the loading rotator 2.
[0012]
A drive frame 19 is integrally provided inside the main body housing 1 at the lower ends of the left and right rods 16 a of the upper frame 16, and this drive frame 19 is connected to the tip of the swing arm 21 via a pin 20. Linked together. The pin 20 has a non-circular cross section like a cam in order to finely adjust the vertical movement speed of the drive frame 19 and the like. The swing arm 21 is provided with a cam follower 22 attached in the middle. The cam follower 22 is in contact with a cam 23 made of an eccentric ring attached to the transmission shaft 9. The swing arm 21 swings up and down around the support shaft 24 at the base end. In this way, the drive frame 19, the upper and lower frames 16, 17 provided on the upper portion thereof, and the cutting blade 3 integrally move up and down in conjunction with the swing arm 21. In this case, the vertical movement of the cutting blade 3 and the like is synchronized with the intermittent rotation of the carry-in rotator 2, and when the carry-in rotator 2 is fed and rotated, the cutting blade 3 is lowered and the rotation of the carry-in rotator 2 is stopped. Sometimes, the cutting blade 3 rises and returns to the original high position.
[0013]
The carry-out conveyor 4 is for carrying out the cut rolled sushi discharged to the back of the cutting blade 3, and includes a roller 25, a belt guide 26 extending in the vicinity of the back of the cutting blade 3, the rollers 25 and Although not shown, the belt 27 is driven around the belt guide 26 and is driven by the motor 7 in conjunction with the transmission shaft 9 and a transmission mechanism such as a chain.
[0014]
The operation of the above configuration will be described with reference to FIG. 3. When the carry-in rotating body 2 stops intermittent rotation, as shown in FIG. The installation surface is upward and almost horizontal. The bar-shaped rolled sushi M to be cut is placed on the corner of the holding portion 14 by hand or mechanically. Thereafter, the carry-in rotating body 2 starts feeding rotation, and the rolled sushi M is conveyed along a circular path to the lower front.
On the other hand, the cutting blade 3 is in the raised position when the carry-in rotating body 2 is stopped, and descends in synchronization with the feed-in rotation of the carry-in rotating body 2.
Thus, when the rolled sushi M supplied to the carry-in rotator 2 is fed to the cutting blade 3 side, the cutting blade 3 descends, so that the leading edge of the cutting blade 3 cuts into the rolled sushi M first. A cut edge is made, and a vertically long blade portion enters deeply and acts over a long distance in the vertical direction. Just like when cutting a fish fillet with a willow blade knife, it is cut at once. Thus, the entire stick-shaped sushi roll M is cut into a large number of bite-sized sushi at once.
In this case, the stick-shaped sushi roll M is sent while changing the rotation angle so as to roll with respect to the cutting blade 3 as shown in FIG. The cutting blade 3 acts on a wide angular range of the outer periphery of the rolled sushi M. Thus, the cutting blade 3 cuts and cuts into the cross-section of the rolled sushi M while changing the angular position continuously acting without concentrating the cutting force at one place on the outer periphery of the rolled sushi M. To. Therefore, the cut end is beautiful and carving is performed without loss of shape.
[0015]
When the holding part 14 of the carrying-in rotating body 2 is turned downward, the leading edge of the blade part of the cutting blade 3 passes through the holding part 14 and enters the back of the gap 15 between the element bodies 2a and 2a. Sushi M is completely divided. What is cut into a bite-sized width passes through the interval between the cutting blades 3 and falls onto the carry-out conveyor 4 below. At this time, since the cut pieces fall in a state where they are lined up almost without any gap, they are also held on the carry-out conveyor 4 and are conveyed to the end of the carry-out conveyor 4 in an aligned state.
When the rolled sushi M supplied on one of the holding portions 14 of the carry-in rotating body 2 is cut and released, the rotation of the carry-in rotating body 2 is stopped. At this time, the subsequent holding of the carry-in rotating body 2 is stopped. The part 14 is in a position to receive the rolled sushi M, and the cutting blade 3 has returned from the lowered position to the raised position before cutting. Thus, the cutting machine returns to its original state, and the series of operations described above are repeated, and the stick-shaped sushi rolls are cut one after another.
[0016]
As described above, the rolled sushi cutting machine according to claim 1 holds the stick-shaped rolled sushi to be cut in a laterally horizontal posture toward the cutting position, and holds this in a substantially arc shape from a high position to a front low position. Loading means for feeding along the path, and a plurality of sheets arranged at a predetermined angle on the right and left sides at a predetermined angle to the loading means side at a position intersecting the front portion of the feeding path of the loading means. A vertically long cutting blade that descends synchronously, a carry-out conveyor that carries the cut sushi cut behind the cutting blade in a substantially aligned state, and an intermittent for rotating the carry-in rotating body that is the carry-in means intermittently A rolling mechanism is included, and the circumferential portion of the carry-in means has a structure in which each cutting blade is vertically movable according to the arrangement interval of the cutting blades. With a vertically long cutting blade It works for a long distance in the vertical direction after being cut in a state, and it will be drawn at a stretch just like cutting a fish fillet with a willow blade knife, and sushi rolls are sent along an arcuate path Because the rotation angle is changed so that it rolls against the cutting blade, the cutting blade acts on a wide angular range of the outer periphery of the rolled sushi, and the cutting force of the cutting blade is concentrated at one place on the outer peripheral portion of the rolled sushi There is nothing to do. Therefore, it is possible to make a beautiful carving without any shape loss. In addition, since many cutting blades act on a stick-shaped sushi roll at once, it can be cut quickly, and when used in combination with an automatic sushi roll manufacturing device, the production efficiency of sushi rolls can be greatly increased. Can do. In addition, when cutting the whole sushi roll, each cutting blade only acts once on the stick-shaped sushi roll, so the degree of wear is extremely low, and cutting can be done for a long time without replacing the cutting blade. It can be done and does not require much maintenance.
[0017]
In the rolled sushi cutting machine including the configuration according to claim 2, since the carrying-in means is a rotating body, the operation can be easily synchronized with the operation of the cutting blade, and the rotating body includes a plurality of rotating bodies. Because it consists of a plate-shaped body, it is easy to disassemble and assemble, and it is easy to remove the dirt by disassembling and cleaning up to details, and keep the rotating body to which chips are easy to adhere clean. be able to.
In the rolled sushi cutting machine including the configuration according to claim 3, since both ends of the cutting blade are fixed to the upper and lower frames, a thin blade can be used, and the thin blade is slightly worn. Since the leading edge is kept sharp, it can be used for a long period of time, and since the degree to which the cut sushi is pushed is small, the cut sushi is not scattered and can be sent out in an aligned form. And it doesn't take much time to handle afterwards.
