The scraper scraping body 39 is provided with opposing surfaces respectively opposed to the peripheral surface 27a-1 of the rotating cylindrical body 27a, the side surface 27b-1 of the side edge flange 27b, and the side surface 27c-1 of the intermediate flange 27c. The body 27a is configured to scrape off the sticking to the surface of the peripheral surface 27a-1, the side surface 27b-1 of the side edge flange 27b, and the side surface 27c-1 of the intermediate flange 27c.
[0058]
The division unit 29 is configured as described above. Hereinafter, the guide rollers 35a, 35b, 35c, 35d, 35e, 35a ′, 35b ′, 35c ′, 35d ′, and 35e ′, which are the gist of the present invention, will be described in detail.
[0059]
As described above, the guide rollers 35a, 35b, 35c, 35d, 35e are provided on the front wall 24 and the rear wall 25, and the guide rollers 35a ', 35b', 35c ', 35d', 35e 'are provided on the dividing plate 26. Therefore, the divided band-shaped shavings are guided rollers 35a, 35b, 35c, 35d, 35e on the front wall 24 and the rear wall 25, and guide rollers 35a ', 35b', 35c ', 35d', 35e on the divided plate 26. It is configured to be conveyed downward while being pinched by '.
[0060]
Here, the first guide roller 35a on the front wall 24 and the rear wall 25 and the first guide roller 35a 'on the dividing plate 26, the second guide roller 35b on the front wall 24 and the rear wall 25 and the second guide roller on the dividing plate 26. 35b ', the third guide roller 35c of the front wall 24 and the rear wall 25 and the third guide roller 35c' of the dividing plate 26, the fourth guide roller 35d of the front wall 24 and the rear wall 25 and the fourth guide roller of the dividing plate 26 35d ′, the fifth guide roller 35e on the front wall 24 and the rear wall 25, and the fifth guide roller 35e ′ on the divided plate 26 are opposed to each other with the divided band-shaped chatter therebetween.
[0061]
As described above, by providing the guide rollers 35a to 35e ′, the guide rollers 35a to 35e ′ are provided even when the sticky sticky sticks to the guide rollers 35a to 35e ′ when the divided belt-like chatter is fed. Since the rotation of itself does not cause the chatter to stop, it is possible to prevent the feeding of the split belt-shaped chatter due to the stopped chatter and to perform the smooth feeding of the split belt-shaped chatter.
[0062]
In particular, in the chatter ball forming machine A, instead of continuously feeding the divided band-shaped chatter, since feeding is intermittently repeated feeding and stopping, When the feeding is stopped, it becomes very easy to stick when the divided belt-like chatter dries. However, the chatter sticking to the guide roller is adjacent to the downstream side in the transport direction of the guide roller when the guide roller rotates. It is handed over by adhering to the guide roller that has been provided, and can be smoothly fed together with the divided band-shaped shackle.
[0063]
Therefore, even if it is a divided band-shaped chatter that tends to be thin and difficult to maintain its shape by being divided by the dividing unit, it can be fed without causing deformation due to feeding. When a predetermined amount of chatter is divided from the split belt-shaped chatter to form a ball, it is always possible to divide the chatter almost evenly and form a substantially uniform ball.
[0064]
Further, the above-described guide rollers 35a to 35e 'have a diameter dimension equal to or less than the length dimension of the cooked rice constituting the shaving. In particular, in the present embodiment, a cylindrical body is used in which the diameter dimensions of the guide rollers 35a to 35e ′ are the same as the length dimension of the cooked rice constituting the shaving, that is, about 6 mm.
[0065]
Thus, by making the diameter dimension of the guide rollers 35a to 35e ′ equal to or less than the length dimension of the cooked rice constituting the shaving, a sufficient contact area between the guiding rollers 35a to 35e ′ and the shaving is obtained. Since the guide rollers 35a to 35e 'can be easily rotated following the feeding of the divided band-shaped shawls, it is necessary to provide a drive mechanism for rotating the guide rollers 35a to 35e'. Therefore, the cost can be reduced.
[0066]
On the other hand, the contact time between the guide rollers 35a to 35e ′ and the chatter can be made relatively short, and the chatter can be prevented from sticking firmly to the guide rollers 35a to 35e ′.
[0067]
In addition, since the concave shape of the concave portion formed between the guide rollers 35a to 35e ′ and the guide rollers 35a to 35e ′ can be reduced, it is possible to prevent the shading from stopping in the concave portion and It is possible to prevent the rotation of the guide rollers 35a to 35e ′ from being hindered by the chattering at the portion.
[0068]
In this embodiment, the lengths of the first guide rollers 35a and 35a ′ and the second guide rollers 35b and 35b ′ are shorter than the third to fourth guide rollers 35c to 35e ′.
[0069]
This not only allows the first guide rollers 35a and 35a 'to be closer to the communication portion 33, but also shortens the length of the first guide rollers 35a and 35a' located on the upstream side in the feeding of the divided band-shaped chatter. This makes it easier to rotate the first guide rollers 35a and 35a '.
[0070]
That is, the divided band-shaped chatter tends to have a relatively high density of chatter in the central portion as it is divided by the dividing plate 26. Accordingly, the first guide rollers 35a, 35a 'strongly abuts against the divided band-shaped chatter only in the vicinity of the central portion of the first guide rollers 35a, 35a'. Therefore, the first guide rollers 35a and 35a ′ are likely to bend due to the pressure from the divided band-shaped shackle, and the smooth rotation of the first guide rollers 35a and 35a ′ may be hindered by the deflection.
[0071]
Therefore, by shortening the length of the first guide rollers 35a, 35a ′, the structural rigidity of the first guide rollers 35a, 35a ′ is increased, and the occurrence of bending is suppressed, so that the first guide rollers 35a, 35a ′ It is configured to always rotate smoothly.
[0072]
On the other hand, the first guide rollers 35a and 35a 'resist the pressure that causes the first guide rollers 35a and 35a' to bend, so that the first guide rollers 35a and 35a 'form the divided band-shaped shackles. Can do. In other words, the divided band-shaped chatter is pressed by the first guide rollers 35a, 35a ′ that are in contact with the central part of the divided band-shaped chatter, so that the central band is bent in the side edge direction. The density of the central portion, which is relatively high in density, can be lowered to form a divided band-shaped chatter having a uniform density as a whole.
[0073]
For the same reason, in this embodiment, the second guide rollers 35b and 35b ′ are shorter than the third to fourth guide rollers 35c to 35e ′. The length of the guide roller may be gradually increased from the first guide roller 35a, 35a ′ to the fifth guide roller 35e, 35e ′.
[0074]
In the above-described embodiment, five guide rollers 35a to 35e ′ are provided on each guide surface 34, 34 ′, but the number is not limited to five, and may be five or more. It may be 5 or less.
[0075]
Further, in the above-described embodiment, in order to prevent density variation from occurring in the divided strip-shaped chatter that has become thin due to the stoppage of the chatter, the guide surfaces 34, 34 ′ below the communication portion 33 are provided on the guide surfaces 34, 34 ′. Although only the guide rollers 35a to 35e ′ are provided, the guide roller may be provided on the guide surface 34 above the communication portion 33.

【The invention's effect】
According to the first aspect of the present invention, a band-shaped chatter having a predetermined thickness is fed and the band-shaped chatter is fed. Is divided into multiple strips by a split unit, and the strips are split In the squirrel ball forming machine that separates the shave by a predetermined amount from The dividing unit is positioned between the front wall, the rear wall, a pair of molding rollers laid between the front wall and the rear wall, and between the front wall and the rear wall and below the molding roller. It is composed of the divided plates and is in sliding contact with the belt-shaped chatter, and guides the feeding of the belt-shaped chatter on each of the guide surfaces of the front wall, the rear wall, and the split plate, By arranging a plurality of guide rollers in a rotatable manner and guiding the belt-shaped chatter with this guide roller, even if sticky chatter sticks to the guide roller, it can feed the chatter. Along with the rotation of the guide roller, the chatter adhered to the guide roller is also conveyed, and the chatter adheres to the guide roller adjacent to the adhered guide roller, so that the chatter does not stop. Can be sent. Therefore, it is possible to smoothly feed the belt-shaped chatter, and to prevent density fluctuations from occurring in the belt-shaped chatter during feeding. It can be formed uniformly.
[0077]
Also, It is possible to feed the belt-shaped shaver without causing a shape loss to the thin-shaped shaver due to the division by the dividing unit. When dividing the shaving, it can be divided almost evenly.
[0078]
Claim 2 According to the described invention, the guide roller can be easily and reliably made to follow the feeding of the belt-shaped shaving by making the diameter of the guide roller less than or equal to the length of the cooked rice. On the other hand, the contact time between the guide roller and the chatter can be shortened, and the chatter can be prevented from sticking firmly to the guide roller. In addition, the concave shape of the concave portion formed between the guide roller and the guide roller can be reduced, and chatter can be prevented from stopping in the concave portion, and the chatter can be stopped in the concave portion. It can prevent obstructing rotation of a guide roller.
