Description

DETAILED DESCRIPTION OF THE INVENTION This invention aims to reduce the variation in the weight of a packaged mochi made by packaging a certain number of mochi pieces together by reducing the variation in the weight of each mochi piece. This invention relates to a cutting method and a cutting machine.

Traditionally, noshi mochi is cut into pieces of appropriate size,
There is a method of packaging and selling several pieces of noshi mochi, but the currently sold packaged mochi are cut to a uniform width and length, so if the thickness of the noshi mochi varies, only one piece will be sold. The variation in the grain size of the mochi pieces increases. Therefore, it is not uncommon for the total weight of several rice cake pieces packed together to vary by 10% or more. This is because, for example, one piece of mochi weighs 45g.
In the case of a package of 10 rice cakes, it is displayed as 450g, but if the actual weight is 448g, it is less than the indicated weight, so it is necessary to add one extra piece. It will increase by 10%. Similarly, if 10 pieces weigh 480g, then 1 piece (48g
If removed, the weight becomes 432g, so it cannot be removed as long as it is sold as 450g.

Therefore, if you make the thickness of the rice cakes accurate, there will be less variation in the weight per piece, but if it were 44g, you would have to add one extra piece to make it 484g.
In other words, as a seller, you must always make the weight larger than the indicated weight. For example, if the average is 47g
10 pieces weighs 470g, which is still quite a lot.
If it is 46g, it becomes 460g, which improves the accuracy considerably.
Shimochi, on the other hand, usually has its peripheral wall and bottom constrained, so the dimensions of these parts are fairly accurate, but it is extremely difficult to make the top surface highly accurate, and even if you try to make it to the exact thickness while it is still soft. However, it is extremely difficult to achieve the same level of precision as industrial products, as variations in thickness may occur during curing. On the other hand, width cutting can be done accurately, so if you detect the thickness, calculate the length based on this detected value, and cut according to this calculated length, the variation in the weight of one mochi will be extremely small. .

This invention is based on the above-mentioned theory and has enabled industrialization thereof. That is, the method of the present invention involves cutting both width edges of Noshimochi 1, which has been hardened to a thickness of 15 mm, width of 380 mm, and length of 850 mm, to a length of 5 mm, and cutting a width of 27/3 to a width of 27/3.
Cut into 10 strips of mochi 1a (thickness 15 mm, width 37 mm, length 850 mm) of 7 mm each. Next, line them up with the thicker sides up and down and tighten them into one bundle. This bunch mochi 1
b has a thickness of 37 mm, a width of 150 mm, and a length of 850 mm. Therefore, the width of the bundle mochi is continuously measured from the tip side, and the measured value is stored in the calculator. The width of the bundle mochi in the above is 150 mm, but this is a calculated value based on the thickness of 15 rice cakes, assuming that the thickness of the rice cake is 15 mm.

However, even if the noshi mochi is placed in a container and cured to a thickness of 15 mm, it is extremely difficult to make the thickness of the rice cake exactly 15 mm. This is because the bottom surface of Noshimochi is flat, but the top surface is open, so the thickness is usually 14.8 mm or 15.1 mm depending on the location. Therefore, we measure the bundle mochi in bulk, and if the thickness of 10 pieces becomes 155 mm or 148 mm, we take into account the length cutting and make the weight of 1 piece of mochi 1 c to approximately 45 g. It is. Incidentally, a 45g mochi piece is 15mm thick, 37mm wide, and 70mm long. In the above, the width of 37 mm is cut to a constant width, so the thickness
Measure the 15mm variation, adjust the length to 70mm (for example, 69mm or 72mm), and make a piece of mochi weighing 45g. As mentioned above, if the weight of one packaged rice cake is 450g, it is good to have more than 450g, but 450g is better.
Since it is not possible to sell products weighing less than 100g, they are always cut to the calculated length on the tenth side. According to the conventional example, the variation in one package of 450 g of rice cake was usually about 10%, but according to the present invention, the variation could be reduced to 2.5% or less. Therefore, the weight of a fixed amount of 450g of packaged mochi had a variation of about 45g (one piece of 10-piece packaging), but by the method of this invention, it was possible to suppress the variation to about 12g. It can be seen that it has been significantly streamlined.

Next, an embodiment of the present invention will be explained based on the drawings.

In Figures 2 and 3, Noshimochi 1 is on the right side.
A roller stand 2 on which the mochi is placed is installed, a roller conveyor 3 is connected to the roller stand 2, and a disk-shaped rotary blade 4 is connected to a rotating shaft 5 installed between the roller conveyors 3 at right angles to the direction of movement of the rice cakes. A width cutting device A fixed to the width cutting device A, and a primary alignment roller B fixed to the rotating shafts 6 and 7 installed perpendicular to the direction of movement of the noshi mochi and vertically parallel to each other and rollers 8 and 9 having annular irregularities with a serrated cross section fixed thereto.
(Fig. 7), and a secondary alignment roller C (Fig. 8) in which disks 12 and 13 are fixed at a predetermined interval to rotating shafts 10 and 11 installed above and below the rotating shaft 6 at a predetermined interval and in parallel with each other. ) and will be installed in sequence. The primary alignment roller B raises and aligns the strips of rice cakes at an angle of about 45 degrees from the horizontal, and the secondary alignment roller raises the strips of rice cakes at an angle of about 85 degrees. The disks of the secondary alignment rollers C are fixed in parallel to the rotating shaft 10 via bosses 18 at regular intervals. Further, the disks 13 are fixed in parallel to the rotating shaft 11 at regular intervals via bosses 19, and the disks 13 are made up of two disks a and b, and are fixed so that the bosses 19 face each other. The opposing surface of the disc 13 is gently sloped inward. The circumferential edge of the front disk 12 is exposed to the middle part of the pair of disks a and b, and the disk 12 is gradually inclined from the circumferential edge toward the boss to increase its thickness. The inclination angles of the side walls of the disks 12 and 13 are made almost equal (FIG. 8), so that both disks 12,
A strip-shaped mochi 1b is inserted between the peripheral parts of 13,
The strip-shaped mochi is then raised on the primary alignment roller B. This rising angle is determined by the inclination of the side walls of the disks 12, 13, and is approximately 80 to 85 degrees with respect to the horizontal. After doing this, it is further advanced and sent between the guide plates 14 and 14a. Next, the guide plates 14 and 14a ensure that the wide sides of the strip-shaped rice cakes are vertical, and the strips of rice cake are moved toward each other. The guide plates 14, 14a are shaped like eight characters (Fig. 3) in plan view, with the entrance side of the rectangular rice cake widened.
The strip-shaped rice cakes are brought together in progress (arrow 15 in Fig. 3). As shown in FIG. 1, the rice cakes are vertically cut in the width direction, and when they are stood up, gaps are created between them due to the difference in width and thickness, so they are brought together by the guide plate. A conveyor 16 is laid horizontally in the lower part between the guide plates 14 and 14a,
The strip-shaped rice cakes move toward each other as shown by the arrow 15, and then move onto the conveyor 17 of the measuring section. Measuring part D is a guide plate 2 with strips of mochi arranged in parallel.
It is composed of a retaining device 21 that presses and fixes the mochi to the 0 side, and a sensor device 22 that measures the total thickness of the retained mochi (for example, the thickness of 10 pieces). Guide rods 23, 23a installed parallel to the traveling direction, a screw rod 24, and a detection device 25 are placed on the guide rods 23, 23a.
23a (FIGS. 9 and 11). By starting the stepping motor 27 connected to one end of the screw rod 24, the sliding table 2
6 can be slid to the right or left as indicated by arrow 28 in FIG. In this way, the thickness of the strip-shaped rice cake in the direction perpendicular to the traveling direction is measured in correspondence with the distance from the traveling direction, and the measured value is stored in the detection section of the sensor. At the advancing end of the measurement section D, there is a tip cutting device E for cutting the tip of the strip-shaped rice cake.
There is. A cutting device F is installed in parallel to the measuring section D at a predetermined interval, and the measuring section D and the cutting device F
and are connected by a conveying device G.

Next, in FIG. 4, when the motor 30 is started, the sprocket wheel 35 of the receiving roll 34 is rotated via the reducer 31, the sprocket wheel 32 fixed to its output shaft, and the chain 33. The rotary blade 4 is rotated by movement with the axis of the rotary blade 4 (coupled with gears, not shown), and the rice cake is cut into strips as described above. Also, a sprocket wheel 36 fixed to the shaft of the receiving roll and a sprocket wheel 3 on the intermediate shaft
7. The receiving roll 39 is rotated by the chain 38, the end rice cakes 40 are cut by the rotary blade 41, and the scraps are conveyed to one side by the waste receiving conveyor 42. The waste conveyor 42 is driven via a motor 43 and sprockets 44, 45. Also, from the motor 46, the reducer 47,
Sprocket wheel 48, chain 49, sprocket wheels 50, 51, chain 52, sprocket wheel 53, gears 54, 55, 5
6, 57, etc., the primary alignment roller B and the secondary alignment roller C are rotated, respectively.

Next, in FIG. 5, when the motor 58 is started, the sprocket wheel 61 is rotated via the sprocket wheel 59 and the chain 60, and one end of the arm 63 is attached eccentrically to a disk 62 coaxial with the sprocket wheel 61, and the other end of the arm 63 is attached eccentrically to a disc 62 coaxial with the sprocket wheel 61. is attached to the lifting body 65 for attaching the cutting blade 64. Therefore, when the disk 62 is rotated, the cutting blade 64 moves up and down as shown by the arrow 66, and can cut off the tip of the sticky rice cake. Also, the motor 92
The belt conveyor 17 can be moved as shown by the arrow 97 via the pulley 93, the timing belt 94, and the pulley 95, and the bundle mochi can be moved to a predetermined position.

Further, in FIG. 6, when the motor 67 is started, the belt conveyor is moved via a pulley 68, a timing belt 69, and a pulley 70. This motor 67 moves intermittently in the direction of an arrow 72 by a distance calculated based on the detected thickness of the sticky rice cake measured by the sensor. Further, it rotates a pulley 74, which is a driven shaft of a belt conveyor 71, via a pulley coaxial with the pulley 70 and a pulley 73, which is an intermediate shaft, and via timing belts 75 and 76.
In other words, both ends of the belt conveyor 71 are driven. Also, by starting the motor 77, the pulley 78, timing belt 79, pulley 80, clutch 81, pulley 82, timing belt 83, pulley 84, transmission 85, pulley 86, timing belt 87, pulley 8
8, the eccentric wheel 89 is rotated, and the cutting blade 91 is raised and lowered via the connecting rod 90, and while the belt conveyor 71 is moved intermittently as described above, when the belt conveyor 71 is stopped, the cutting blade 91 is lowered to cut the bundle mochi. disconnect. Therefore, the cutting length of the rice cake pieces varies depending on the amount of intermittent movement, and as a result, variations in the weight of the rice cake pieces can be made extremely small.

Next, FIGS. 14 and 15 show a device for aligning the tips of bundle mochi that have been advanced side by side. That is, the bundle rice cakes transported by the belt conveyor 17 are placed on the guide plate 20.
14, and are held closely together by the pressing piece 21 as shown in FIG. In this case, when pressurized fluid is supplied to the lower part of the fluid pressure cylinder 99, the shaft 102 is rotated via the piston rod and the arm 101 connected thereto, and the fixed plate 102 fixed to the shaft 102 is rotated.
is rotated so that it comes into contact with the end surface of the bundle mochi 1b, and its tip is aligned at a fixed position. Then, as described above, the cutting blade 6
4 and cut off a little width at the tip, the unstable part of the thickness will be removed, and the subsequent weight accuracy can be maintained at a high level.

Next, FIG. 12 shows a device for tightening and holding the bundle mochi while transporting the bundle mochi from the cutting device E to the cutting device F. That is, the holding body 104 (there are two on the left and right)
A fixed clamping plate 105 is vertically protruded from one side of the lower part of the
The base end of the hydraulic cylinder 106 is fixed horizontally to the fixed clamping plate 105, and the movable clamping piece 107 is attached to the end of the piston rod 109 of the hydraulic cylinder 106. Then, move the piston rod to arrow 1 in Figure 15.
When retracted as shown in 08, the movable clamping piece 107 and the fixed clamping plate can firmly hold the bundle mochi.

That is, according to the present invention, a rice cake is cut into strips having the same width, the width side thereof is set vertically, a predetermined number of strips of rice cake are set as one set, and the total thickness of the set is detected, and the total thickness of the set is detected based on the detected value. Since the rice cake pieces are cut into lengths that have a set weight, even if the rice cakes have different thicknesses, the variation in weight of the cut rice cake pieces is extremely small. Therefore, the variation in the total weight when a certain number (for example, 10 pieces) is packaged becomes relatively small, which has the effect of streamlining. Further, according to the device of the present invention, a width cutting device,
Since the aligning device, the width measuring device, and the length cutting device are connected in sequence, there is an effect that the rice cake can be automatically cut into pieces of constant weight according to the thickness of the rice cake.
