Description

本発明は、軍艦巻きの製造に使用される海苔巻き付け装置に関するものである。ここで、軍艦巻きとは、舎利玉の周りを海苔で巻き、ウニやイクラなどのすし種をのせてつくられる巻きずしである。 The present invention relates to a laver wrapping device used for manufacturing warship winding. Here, the warship roll is a roll made from seaweed wrapped with seaweed and topped with sushi seeds such as sea urchin and salmon roe.

従来、舎利玉に海苔を巻き付ける複数の接触片と、それぞれが各接触片の回転中心となる複数の回転軸とを具備する海苔巻き付け装置が知られている。
しかしながら、例えば、特開２００２−３２０４５７号公報に開示された海苔巻き付け装置では、接触片が４つあり、各接触片に所定の動作をさせるための構造が複雑で部品点数も多いという問題がある。また、左右に配置された接触片同士を互いに近接又は離間させる方向へスライドさせる構成であるため、１個の舎利玉に海苔を巻き付けるために要する時間として、実際に海苔を巻き付ける時間に、接触片をスライドさせる時間も加わることになり、その結果、生産速度が遅くなるという問題もある。 2. Description of the Related Art Conventionally, a laver wrapping apparatus is known that includes a plurality of contact pieces that wrap seaweed around a rice ball and a plurality of rotation shafts that are the rotation centers of the contact pieces.
However, for example, in the laver wrapping device disclosed in Japanese Patent Application Laid-Open No. 2002-320457, there are four contact pieces, and there is a problem that the structure for causing each contact piece to perform a predetermined operation is complicated and has a large number of parts. . In addition, since the contact pieces arranged on the left and right sides are slid in the direction to approach or separate from each other, the contact pieces are actually taken as the time required to wind the seaweed around one piece of rice. There is also a problem that the production speed becomes slow as a result of adding time for sliding.

一方、特開２００２−３３５８８７号公報には、接触片を２つとし、各接触片を回転させながら移動させて、舎利玉に海苔を巻き付ける構成が開示されている。
しかしながら、この構成では、各接触片の回転中心となる軸も移動させなければならず、そのような動作を実現するための構造が複雑であり、かつ多くの部品を必要とするという問題がある。また、この構成でも、接触片同士を互いに近接又は離間させる方向へスライドさせるため、生産速度が遅くなるという問題がある。 On the other hand, Japanese Patent Application Laid-Open No. 2002-335887 discloses a configuration in which there are two contact pieces, each contact piece is moved while being rotated, and nori is wrapped around the rice cake.
However, with this configuration, there is a problem in that the axis serving as the rotation center of each contact piece must also be moved, the structure for realizing such an operation is complicated, and many parts are required. . In addition, even in this configuration, the contact pieces are slid in a direction to approach or separate from each other, so that there is a problem that the production speed is slow.

また、特開平１０−３０４８３４号公報には、軍艦巻きの品質を高めるために、すなわち、海苔の剥離を防止するために、所定の形状の接触片により、海苔同士が重なる部分を強く押圧することができる構成が開示されている。
しかしながら、舎利玉の周りに海苔が巻き付くのは、米飯の粘着性によるものであり、海苔同士では貼り付かないため、海苔同士が重なる部分を強く押圧しても、海苔の剥離は生じるし、そのような構成を採用していないものと比較しても、海苔の剥離し易さという点において大差がない。 Japanese Patent Laid-Open No. 10-304834 discloses that, in order to improve the quality of warship winding, that is, to prevent peeling of seaweed, a portion having a predetermined shape is pressed strongly with a contact piece of seaweed. The structure which can do is disclosed.
However, it is due to the stickiness of the cooked rice that the seaweed wraps around the sushi balls, and it does not stick between the seaweeds, so even if you press strongly the part where the seaweeds overlap, the seaweed will peel off, Even when compared with those that do not employ such a configuration, there is no significant difference in the ease of peeling of seaweed.

It becomes possible to rotate around the basin balls around each rotation axis without hindering the transfer of the. Therefore, it is not necessary to have a configuration for moving each rotary shaft, and a configuration for applying a rotational force to each rotary shaft is sufficient, so that the structure is greatly simplified as compared with conventional devices. Is possible.
Moreover, since each contact piece has the 1st and 2nd contact surface, and performs the said predetermined | prescribed operation | movement, when laver is wrapped around the sardine ball, the sardine ball does not fall down and laver is It can be wound quickly. Therefore, compared with the conventional apparatus, the operation of winding nori is simple, and the production speed can be significantly increased.

以下、本発明の実施の形態を図面に示した実施例に従って説明する。 Hereinafter, embodiments of the present invention will be described with reference to examples shown in the drawings.

図１は、本発明の実施例１に係る海苔巻き付け装置を示す概略平面図である。この図に示したように、本実施例に係る海苔巻き付け装置は、相互に対向して配置される２つの接触片１，２と、それぞれが各接触片１，２の回転中心となる２つの回転軸３，４とを有して構成される。 FIG. 1 is a schematic plan view showing a laver wrapping apparatus according to Embodiment 1 of the present invention. As shown in this figure, the laver wrapping apparatus according to the present embodiment includes two contact pieces 1 and 2 that are arranged to face each other, and two contact pieces 1 and 2 that are the rotation centers of the contact pieces 1 and 2, respectively. The rotary shafts 3 and 4 are included.

各接触片１，２は、それぞれ接続部１ａ，２ａを介して各回転軸３，４に取り付けられている（図２参照）。各接触片１，２は、洗浄を行うために、取り外し可能であることが好ましい。本実施例では、各接触片１，２と各接続部１ａ，２ａがそれぞれ一体に成形されており、各接続部１ａ，２ａに形成された孔に差し込まれて各回転軸３，４に係合する係合ピン５ａ，５ｂと各回転軸３，４との係合状態を解除することで、各接触片１，２を取り外すことができるようになっている。 The contact pieces 1 and 2 are attached to the rotary shafts 3 and 4 via connection portions 1a and 2a, respectively (see FIG. 2). Each contact piece 1, 2 is preferably removable for cleaning. In the present embodiment, the contact pieces 1 and 2 and the connection portions 1a and 2a are integrally formed, and are inserted into holes formed in the connection portions 1a and 2a to be connected to the rotary shafts 3 and 4, respectively. The contact pieces 1 and 2 can be removed by releasing the engaged state between the mating engagement pins 5a and 5b and the rotary shafts 3 and 4.

各接触片１，２は、第１接触面１ｂ，２ｂと第２接触面１ｃ，２ｃとを有する（図４（ａ）参照）。第１接触面１ｂ，２ｂは、舎利玉１０の進行方向前側の平坦面１０ａに海苔１１を介して接触する面であり、第２接触面１ｃ，２ｃは、舎利玉１０の進行方向後側の平坦面１０ｂに海苔１１を介して接触する面である。 Each contact piece 1 and 2 has 1st contact surface 1b, 2b and 2nd contact surface 1c, 2c (refer Fig.4 (a)). The first contact surfaces 1b and 2b are surfaces that come into contact with the flat surface 10a on the front side in the direction of travel of the rice cake 10 through the laver 11, and the second contact surfaces 1c and 2c are on the rear side in the direction of travel of the rice cake ball 10. It is a surface which contacts the flat surface 10b through the laver 11.

ここで、舎利玉１０は、米飯（すし飯）の塊であり、その周面は、略平行な２つの平坦面１０ａ，１０ｂと、両側に存する２つの曲面１０ｃ，１０ｄとを有する（図３参照）。舎利玉１０は、人の手により握られたものであってもよいし、機械を用いて成形されたものであってもよい。 Here, the rice 10 is a lump of cooked rice (sushi rice), and its peripheral surface has two substantially parallel flat surfaces 10a and 10b and two curved surfaces 10c and 10d existing on both sides (see FIG. 3). ). The rice ball 10 may be held by a human hand, or may be molded using a machine.

各接触片１，２の好ましい形態としては、図４（ａ）に示したように、各接触片１，２の回転中心Ａ，Ａが、平面視で舎利玉１０の両側に存する２つの円弧の中心Ｂ，Ｂよりもそれぞれ外側であって、各円弧Ｂ，Ｂの中心を結ぶ仮想線Ｃよりもそれぞれ前方に位置するように設定され、かつ各接触片１，２が、第１接触面１ｂ，２ｂと第２接触面１ｃ，２ｃとの間であって、前記仮想線Ｃよりも前方の位置に、第１接触面１ｂ，２ｂ及び第２接触面１ｃ，２ｃよりも内側に突出する押圧部１ｄ，２ｄを有することである。 As a preferred form of each contact piece 1, as shown in FIG. 4A, the rotation centers A and A of each contact piece 1 and 2 are two arcs that exist on both sides of the building ball 10 in plan view. Are set so as to be located respectively outside the virtual lines C connecting the centers of the arcs B and B, respectively, and the contact pieces 1 and 2 are respectively connected to the first contact surface. 1b, 2b and the second contact surfaces 1c, 2c, projecting inward of the first contact surfaces 1b, 2b and the second contact surfaces 1c, 2c at positions ahead of the virtual line C It has press parts 1d and 2d.

舎利玉１０に巻き付けられる海苔１１の全長は、舎利玉１０の周囲よりも長く設定されるのが一般であり、そのため、舎利玉１０に海苔１１を巻き付けたときには、海苔１１の端部１１ａ，１１ｂ同士が重なり合うことになる（図３参照）。この際、海苔１１の一方の端部１１ａは、舎利玉１０に接して、舎利玉１０に貼り付くが、一方の端部１１ａに重なる海苔１１の他方の端部１１ｂは、海苔１１同士では貼り付かないため、どこにも貼り付かない状態となる。その結果、特に海苔１１の他方の端部１１ｂ側が舎利玉１０から剥離し易くなる。 Generally, the total length of the seaweed 11 wound around the sardine ball 10 is set to be longer than the periphery of the sardine ball 10, so that when the seaweed 11 is wrapped around the sardine ball 10, the end portions 11 a and 11 b of the seaweed 11 are arranged. They overlap each other (see FIG. 3). At this time, one end 11a of the laver 11 is in contact with the sardine ball 10 and sticks to the sardine ball 10, but the other end 11b of the laver 11 that overlaps the one end 11a is pasted between the laver 11s. Since it does not stick, it will not stick anywhere. As a result, in particular, the other end 11 b side of the laver 11 is easily peeled off from the bowl 10.

そこで、海苔１１の剥離を防ぐには、どの部分を強く押圧するのが効果的であるのか鋭意検討するとともに、その検討内容に基づいて幾度も実験を行った結果、舎利玉１０の進行方向後側における平坦面１０ｂと曲面１０ｃ，１０ｄとの境界部分Ｄ（図３参照）を強く押圧すれば、海苔１１の剥離が生じ難くなることを見出した。上記した各接触片１，２の好ましい形態によれば、図４（ｂ）に示したように、各接触片１，２の押圧部１ｄ，２ｄにより、舎利玉１０の進行方向後側における平坦面１０ｂと曲面１０ｃ，１０ｄとの境界部分Ｄを強く押圧することができる。なお、各接触片１，２の形態が、上記した形態に限定されるものではないことは勿論である。 Therefore, in order to prevent the laver 11 from being peeled off, it has been intensively investigated which part is effective to press strongly, and as a result of repeated experiments based on the examination content, It has been found that if the boundary portion D (see FIG. 3) between the flat surface 10b and the curved surfaces 10c and 10d on the side is strongly pressed, the laver 11 is less likely to be peeled off. According to the preferable form of each contact piece 1 and 2 described above, as shown in FIG. 4 (b), the pressing portion 1d and 2d of each contact piece 1 and 2 is flat on the rear side in the traveling direction of the building ball 10. The boundary portion D between the surface 10b and the curved surfaces 10c and 10d can be strongly pressed. Of course, the form of each contact piece 1, 2 is not limited to the form described above.

各回転軸３，４は、海苔１１を巻き付ける位置に停止した舎利玉１０の上に配置される。従来の装置では、いずれも回転軸が舎利玉の周りに配置され、また、各接触片が海苔の巻き付け終了後に舎利玉の移送の妨げとなるため、回転軸自体を移動させるための構成が必要であった。 Each rotating shaft 3 and 4 is arrange | positioned on the rice ball 10 stopped in the position where the laver 11 is wound. In all the conventional devices, the rotating shaft is arranged around the bowl and each contact piece hinders the transfer of the bowl after the laver has been wound. Therefore, a configuration for moving the shaft itself is necessary. Met.

この点、本実施例では、各回転軸３，４を舎利玉１０の上に配置したことにより、各接触片１，２が海苔１１の巻き付け開始時はもとより終了後においても舎利玉１０の移送の妨げとなることなく、各回転軸３，４を中心として舎利玉１０の周りで回転動作することが可能となる。従って、各回転軸３，４を移動させるための構成が不要であり、各回転軸３，４に回転力を付与するための構成があれば足りるので、従来の装置と比較して、構造を格段に簡素にすることが可能となる。 In this respect, in the present embodiment, the rotary shafts 3 and 4 are arranged on the rice ball 10, so that the contact pieces 1 and 2 are transferred not only at the start of winding the laver 11 but also after the end. Without being obstructed, it is possible to rotate around the staving ball 10 around the rotary shafts 3 and 4. Therefore, a configuration for moving the rotary shafts 3 and 4 is not necessary, and a configuration for applying a rotational force to the rotary shafts 3 and 4 is sufficient. It can be greatly simplified.

各回転軸３，４に回転力を付与するための構成としては、例えば、図５に示したように、各回転軸３，４に設けられる２つの小歯車６ａ’，６ｂ’と、それぞれが各小歯車６ａ’，６ｂ’に噛み合う２つの大歯車６ｃ’，６ｄ’と、各大歯車６ｃ’，６ｄ’をそれぞれ回転させる２つのモータ６ｅ’，６ｆ’とを具備する駆動機構６’を採用することができる。 For example, as shown in FIG. 5, two small gears 6 a ′ and 6 b ′ provided on each of the rotary shafts 3 and 4 are configured to apply a rotational force to each of the rotary shafts 3 and 4. A drive mechanism 6 ′ having two large gears 6c ′ and 6d ′ meshing with the small gears 6a ′ and 6b ′ and two motors 6e ′ and 6f ′ for rotating the large gears 6c ′ and 6d ′, respectively. Can be adopted.

もっとも、かかる駆動機構６’では、大歯車６ｃ’，６ｄ’及びモータ６ｅ’，６ｆ’がそれぞれ２つずつ必要となり、部品点数が多くなる。また、１個の舎利玉１０に海苔１１を巻き付ける間に、モータ６ｅ’，６ｆ’の回転方向を変換しなければならないため、その分、生産速度が低下する。 However, in the drive mechanism 6 ', two large gears 6c' and 6d 'and two motors 6e' and 6f 'are required, and the number of parts increases. Further, since the direction of rotation of the motors 6e 'and 6f' must be changed while the laver 11 is wound around the single rice ball 10, the production speed is reduced accordingly.

なお、かかる駆動機構６’によっても、従来の装置と比較したときには、構造が簡素で、海苔１１を巻き付ける動作も単純であって、生産速度を速くすることができる。因みに、舎利玉１０に海苔１１を巻き付けることができる１時間当たりの個数は、従来の装置では、約１８００〜２０００個（約３０〜３３個／分）であるのに対して、上記駆動機構６’を採用した装置では、約３０００個（約５０個／分、従来比：約１．５培）である。 Note that this drive mechanism 6 'also has a simple structure and a simple operation for winding the laver 11 as compared with the conventional apparatus, and can increase the production speed. Incidentally, the number of hourly seaweed 11 that can be wound around the rice ball 10 is about 1800 to 2000 (about 30 to 33 pieces / minute) in the conventional apparatus, whereas the drive mechanism 6 In the apparatus adopting ', about 3000 pieces (about 50 pieces / minute, conventional ratio: about 1.5 cultivation).

また、他の構成としては、図６に示したように、各回転軸３，４に設けられる２つの小歯車６ａ”，６ｂ”の双方に噛み合う１つの大歯車６ｃ”と、該大歯車６ｃ”を回転させる１つのモータ６ｄ”とを具備する駆動機構６”を採用することもできる。かかる駆動機構６”によれば、大歯車６ｃ”及びモータ６ｄ”がそれぞれ１つずつあれば足りるため、部品点数を少なくすることができる。 As another configuration, as shown in FIG. 6, one large gear 6c "meshing with both of the two small gears 6a" and 6b "provided on the rotary shafts 3 and 4, and the large gear 6c It is also possible to employ a drive mechanism 6 ″ having one motor 6d ″ for rotating “. According to the drive mechanism 6 ″, only one large gear 6c ″ and one motor 6d ″ are required, so that the number of components can be reduced.

もっとも、かかる駆動機構６”でも、上記した駆動機構６’と同様に、１個の舎利玉１０に海苔１１を巻き付ける間に、モータ６ｄ”の回転方向を変換しなければならないため、その分、生産速度が低下する。 However, even in such a drive mechanism 6 ″, the direction of rotation of the motor 6d ″ must be changed while the laver 11 is wound around the single rice ball 10 similarly to the drive mechanism 6 ′ described above. Production speed decreases.

なお、かかる駆動機構６”によっても、従来の装置と比較したときには、構造が簡素で、海苔１１を巻き付ける動作も単純であって、生産速度を速くすることができる。因みに、上記駆動機構６”を採用した装置によって舎利玉１０に海苔１１を巻き付けることができる１時間当たりの個数は、約３０００個（約５０個／分、従来比：約１．５培）である。 Even with such a drive mechanism 6 ″, the structure is simple and the operation of winding the laver 11 is simple as compared with the conventional device, and the production speed can be increased. The number of laver 11 that can be wound around the sardine balls 10 by the apparatus employing the above is about 3000 (about 50 pieces / minute, conventional ratio: about 1.5 cultivation).

本実施例では、各回転軸３，４に回転力を付与するための構成として、図１に示したように、各回転軸３，４に設けられる２つの小歯車６ａ，６ｂの双方に噛み合う１つの大歯車６ｃと、該大歯車６ｃとモータ６ｄとの間に介在して、モータ６ｄの軸が一回転する間に大歯車６ｃを往復回転させるリンク機構７とを具備する駆動機構６が採用される。 In the present embodiment, as shown in FIG. 1, as a configuration for applying a rotational force to each rotary shaft 3, 4, the two small gears 6 a, 6 b provided on each rotary shaft 3, 4 are engaged with each other. A drive mechanism 6 including one large gear 6c and a link mechanism 7 interposed between the large gear 6c and the motor 6d to reciprocately rotate the large gear 6c while the shaft of the motor 6d rotates once. Adopted.

リンク機構７は、さらに、モータ６ｄの軸に連結されるロータ７ａと、該ロータ７ａに一端が回転自在に連結されるアーム７ｂと、該アーム７ｂの他端に回転自在に連結されるとともに、アーム７ｂと大歯車６ｃとの間に介在して、アーム７ｂとの連結部における回転中心Ｅと大歯車６ｃの回転中心Ｆとの間の距離Ｌ（図７参照）を調節可能な調節機構８とを有して構成される（図１参照）。 The link mechanism 7 is further connected to a rotor 7a connected to the shaft of the motor 6d, an arm 7b whose one end is rotatably connected to the rotor 7a, and a rotor 7a that is rotatably connected to the other end of the arm 7b. An adjustment mechanism 8 that is interposed between the arm 7b and the large gear 6c and can adjust the distance L (see FIG. 7) between the rotation center E and the rotation center F of the large gear 6c at the connecting portion with the arm 7b. (See FIG. 1).

ここで、調節機構８は、各回転中心Ｅ，Ｆ間の距離Ｌを調節可能なものであれば、どのような構造のものであってもよい。本実施例で採用した調節機構８は、図７に示したように、大歯車６ｃに形成されたねじ穴に結合するねじ部８ａを有する調節部材８ｂを回転させ、該ねじ部８ａを上記ねじ穴内で進退動作させることにより、各回転中心Ｅ，Ｆ間の距離Ｌを調節することができるようになっている。なお、図７において、８ｃは、アーム７ｂの他端に形成された孔及び調節部材８ｂに形成された孔に挿通されるピンである。また、８ｄは、ピン８ｃの端部に結合して、ピン８ｃの移動を防ぐ止め輪である。 Here, the adjustment mechanism 8 may have any structure as long as the distance L between the rotation centers E and F can be adjusted. As shown in FIG. 7, the adjusting mechanism 8 employed in the present embodiment rotates an adjusting member 8b having a screw portion 8a coupled to a screw hole formed in the large gear 6c, and the screw portion 8a is rotated by the screw screw 8a. The distance L between the rotation centers E and F can be adjusted by moving forward and backward in the hole. In addition, in FIG. 7, 8c is a pin inserted in the hole formed in the other end of the arm 7b, and the hole formed in the adjustment member 8b. Reference numeral 8d denotes a retaining ring that is coupled to the end of the pin 8c to prevent the pin 8c from moving.

上記のように構成される海苔巻き付け装置は、以下のように動作する。すなわち、まず、舎利玉１０が海苔１１を巻き付ける位置に停止したときには、各接触片１，２の長手方向と舎利玉１０の進行方向とが略平行になるように、各接触片１，２が存する（図８（ａ）及び図８（ｂ）参照）。 The laver wrapping apparatus configured as described above operates as follows. That is, first, when the rice cake 10 stops at the position where the laver 11 is wound, the contact pieces 1, 2 are arranged so that the longitudinal direction of each contact piece 1, 2 is substantially parallel to the traveling direction of the rice cake 10. Exist (see FIGS. 8A and 8B).

ここで、舎利玉１０は、移送手段としての回転テーブル９上に載置され、該回転テーブル９が回転することにより、海苔１１を巻き付ける位置まで移送される。海苔１１は、図９に示したように、海苔１１を巻き付ける位置Ｐの手前で供給され、舎利玉１０が海苔１１を巻き付ける位置Ｐに至る前に、舎利玉１０の進行方向前側の平坦面１０ａに貼り付くようになっている。従って、舎利玉１０が海苔１１を巻き付ける位置Ｐに停止したときには、舎利玉１０の進行方向前側の平坦面１０ａに海苔１１が貼り付いている。 Here, the bowl 10 is placed on a rotary table 9 as a transfer means, and is transferred to a position where the laver 11 is wound as the rotary table 9 rotates. As shown in FIG. 9, the laver 11 is supplied in front of the position P where the laver 11 is wound, and the flat surface 10 a on the front side in the traveling direction of the laver 10 before the laver 10 reaches the position P where the laver 11 is wound. It comes to stick to. Therefore, when the sardine ball 10 stops at the position P around which the nori 11 is wound, the nori 11 is stuck on the flat surface 10a on the front side in the traveling direction of the sardine ball 10.

舎利玉１０は、上記のように海苔１１が貼り付いた状態で、各接触片１，２同士の間に移送されるが、この際、海苔１１の両端１１ａ，１１ｂは舎利玉１０に貼り付いていないため、各接触片１，２と舎利玉１０との間に形成される隙間が小さすぎると、舎利玉１０の進入が困難となったり、海苔１１に亀裂が生じたりする。一方、各接触片１，２と舎利玉１０との間に形成される隙間を大きくすると、舎利玉１０の両側に存する２つの曲面１０ｃ，１０ｄに対する海苔１１を介した各接触片１，２の接触の度合いが弱くなり、各曲面１０ｃ，１０ｄへの海苔１１の貼り付き具合が不十分になる。そこで、各接触片１，２と舎利玉１０との間に形成される隙間が小さく、舎利玉１０の進入が円滑に行え、さらに海苔１１に損傷を与えないことが望まれる。 The rice cake 10 is transferred between the contact pieces 1 and 2 with the seaweed 11 attached as described above. At this time, both ends 11a and 11b of the seaweed 11 are attached to the rice cake 10. Therefore, if the gap formed between the contact pieces 1 and 2 and the rice ball 10 is too small, it is difficult for the rice ball 10 to enter, or the laver 11 is cracked. On the other hand, when the gap formed between each contact piece 1, 2 and the styling ball 10 is increased, each contact piece 1, 2 through the laver 11 with respect to the two curved surfaces 10 c, 10 d existing on both sides of the styling ball 10. The degree of contact becomes weak, and the laver 11 sticks to the curved surfaces 10c and 10d. Therefore, it is desired that the gap formed between the contact pieces 1 and 2 and the rice ball 10 is small so that the rice ball 10 can enter smoothly and the laver 11 is not damaged.

この点、本実施例では、各接触片１，２の押圧部１ｄ，２ｄが第２接触面１ｃ，２ｃよりも内側、すなわち、舎利玉１０に近接する方向に突出しているため、各押圧部１ｄ，２ｄと舎利玉１０との間に形成される隙間を小さくしても、各第２接触面１ｃ，２ｃと舎利玉１０との間に形成される隙間は大きくなる。従って、舎利玉１０の進入が円滑に行え、かつ海苔１１に損傷を与えることがない。また、各接触片１，２の回転中心Ａ，Ａが上記所定の位置に設定されるため、舎利玉１０の両側に存する２つの曲面１０ｃ，１０ｄに対する海苔１１を介した各接触片１，２の接触の度合いを強くすることができ、各曲面１０ｃ，１０ｄに対する海苔１１の貼り付き具合を良好なものとすることができる。 In this regard, in this embodiment, the pressing portions 1d and 2d of the contact pieces 1 and 2 protrude inward from the second contact surfaces 1c and 2c, that is, in the direction of approaching the ledge ball 10, so that each pressing portion Even if the gap formed between 1d, 2d and the ledge ball 10 is reduced, the gap formed between each second contact surface 1c, 2c and the ledge ball 10 is increased. Therefore, the entrance of the rice cake 10 can be performed smoothly and the laver 11 is not damaged. Further, since the rotation centers A and A of the contact pieces 1 and 2 are set at the predetermined positions, the contact pieces 1 and 2 through the laver 11 with respect to the two curved surfaces 10c and 10d existing on both sides of the steak ball 10 are provided. The degree of contact of the seaweed 11 can be made good with respect to the curved surfaces 10c and 10d.

次に、モータ６ｄが初期状態（回転角度が０°の状態）から反時計回り方向へ４５°回転したときには、モータ６ｄにリンク機構７を介して連結された大歯車６ｃが初期の位置から反時計回り方向へ２５°回転し、それに伴い各接触片１，２が初期の位置から時計回り方向へ６７°回転する（図１０（ｂ）参照）。 Next, when the motor 6d is rotated 45 ° counterclockwise from the initial state (rotation angle is 0 °), the large gear 6c connected to the motor 6d via the link mechanism 7 is rotated from the initial position. The contact pieces 1 and 2 are rotated by 25 ° in the clockwise direction, and accordingly, the contact pieces 1 and 2 are rotated by 67 ° in the clockwise direction from the initial position (see FIG. 10B).

このとき、一方の接触片１は、押圧部１ｄ付近が舎利玉１０の進行方向後側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動し、また、他方の接触片２は、押圧部２ｄ付近が舎利玉１０の進行方向前側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動する（図１０（ａ）参照）。 At this time, one contact piece 1 moves while contacting the curved surface via the laver 11 so that the vicinity of the pressing portion 1d traces the curved surface on the rear side in the direction of travel of the rice ball 10, and the other contact piece 2 moves while contacting the curved surface through the laver 11 so that the vicinity of the pressing portion 2d follows the curved surface on the front side in the traveling direction of the bowl 10 (see FIG. 10A).

次に、モータ６ｄが初期状態から反時計回り方向へ９４°回転したときには、大歯車６ｃが初期の位置から反時計回り方向へ３７°回転し、それに伴い各接触片１，２が初期の位置から時計回り方向へ９９°回転する（図１１（ｂ）参照）。 Next, when the motor 6d rotates 94 ° counterclockwise from the initial state, the large gear 6c rotates 37 ° counterclockwise from the initial position, and accordingly, the contact pieces 1 and 2 move to the initial positions. Rotate by 99 ° clockwise (see FIG. 11B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄに食い込んで当該部分Ｄを強く押圧し、また、第２接触面１ｃが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１１（ａ）参照）。また、他方の接触片２は、押圧部２ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分に食い込んで当該部分を強く押圧し、また、第１接触面２ｂが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１１（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1d bites into the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building ball 10, and strongly presses the portion D, and the second contact surface 1c. However, the nori 11 is brought into contact with the flat surface of the rice ball 10 via the nori 11 and the nori 11 is pressed against the surface (see FIG. 11A). In the other contact piece 2, the pressing portion 2 d bites into the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building ball 10 and strongly presses the portion, and the first contact surface 2 b has the building block 10. Is brought into contact with the flat surface through the laver 11 and the laver 11 is pressed against the surface (see FIG. 11A).

また、リンク機構７により、各接触片１，２が最大回転角度付近に至るときは、各接触片１，２の回転動作が緩慢になる。すなわち、図１０（ｂ）に示した状態から図１１（ｂ）に示した状態に至るまでの間に、モータ６ｄが回転する角度は４９°であるのに対して、各接触片１，２が回転する角度は３２°であり、そうすると、モータ６ｄが１°回転する毎に各接触片１，２が約０．６５°回転していることになる。一方、図８（ｂ）に示した状態から図１０（ｂ）に示した状態に至るまでの間に、モータ６ｄが回転する角度は４５°であるのに対して、各接触片１，２が回転する角度は６７°であり、そうすると、モータ６ｄが１°回転する毎に各接触片１，２が約１．４９°回転していることになる。モータ６ｄは一定の速度で回転しているから、上記のように各接触片１，２の回転角度が前者と後者で相違するということは、リンク機構７により、各接触片１，２の回転動作が、各接触片１，２の最大回転角度付近で、すなわち、舎利玉１０に海苔１１を確実に巻き付ける上で重要な部分で、他の部分よりも緩慢になるということであり、また、他の部分では、各接触片１，２が素早く回転動作するということである。従って、舎利玉１０に巻き付けられた海苔１１の剥離を生じ難くすることが可能になるとともに、生産速度の低下を抑制することができる。 Further, when the contact pieces 1 and 2 reach the vicinity of the maximum rotation angle by the link mechanism 7, the rotation operation of the contact pieces 1 and 2 becomes slow. That is, the angle of rotation of the motor 6d from the state shown in FIG. 10B to the state shown in FIG. The rotation angle is 32 °. Then, each time the motor 6d rotates 1 °, the contact pieces 1 and 2 rotate about 0.65 °. On the other hand, the angle at which the motor 6d rotates between the state shown in FIG. 8B and the state shown in FIG. The rotation angle is 67 °. Then, each time the motor 6d rotates 1 °, the contact pieces 1 and 2 rotate about 1.49 °. Since the motor 6d rotates at a constant speed, the rotation angle of the contact pieces 1 and 2 is different between the former and the latter as described above. The operation is near the maximum rotation angle of each contact piece 1, 2, that is, an important part for surely winding the laver 11 around the rice ball 10, and is slower than the other parts, In other parts, the contact pieces 1 and 2 rotate quickly. Therefore, it is possible to make it difficult for the laver 11 wound around the rice ball 10 to be peeled off, and to suppress a decrease in production speed.

次に、モータ６ｄが初期状態から反時計回り方向へ１３９°回転したときには、大歯車６ｃが時計回り方向へ回転し、つまり逆転して、初期の位置から反時計回り方向への回転角度が２８°となり、それに伴い各接触片１，２が反時計回り方向へ回転し、つまり逆転して、初期の位置から時計回り方向への回転角度が７５°になる（図１２（ｂ）参照）。 Next, when the motor 6d rotates 139 ° in the counterclockwise direction from the initial state, the large gear 6c rotates in the clockwise direction, that is, reverses, and the rotation angle from the initial position to the counterclockwise direction is 28. Accordingly, the contact pieces 1 and 2 rotate counterclockwise, that is, reversely rotate, and the rotation angle from the initial position to the clockwise direction becomes 75 ° (see FIG. 12B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄを押圧しているが、第２接触面１ｃは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図１２（ａ）参照）。また、他方の接触片２も、押圧部２ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分を押圧しているが、第１接触面２ｂは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図１２（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d presses the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building stone 10, but the second contact surface 1 c is the flat surface of the building glass 10. It leaves | separates from the seaweed 11 stuck on the surface (refer Fig.12 (a)). Further, in the other contact piece 2, the pressing portion 2 d presses the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building stone 10, but the first contact surface 2 b is attached to the flat surface of the building ball 10. It leaves | separates from the attached seaweed 11 (refer Fig.12 (a)).

次に、モータ６ｄが初期状態から反時計回り方向へ１９５°回転したときには、大歯車６ｃが時計回り方向へ回転して、ほぼ初期の位置に復帰し、それに伴い各接触片１，２が反時計回り方向へ回転して、ほぼ初期の位置に復帰する（図１３（ａ）及び図１３（ｂ）参照）。 Next, when the motor 6d rotates 195 ° in the counterclockwise direction from the initial state, the large gear 6c rotates in the clockwise direction and returns to the almost initial position. It rotates clockwise and returns to an almost initial position (see FIGS. 13 (a) and 13 (b)).

次に、モータ６ｄが初期状態から反時計回り方向へ２４０°回転したときには、大歯車６ｃが初期の位置から時計回り方向へ２８°回転し、それに伴い各接触片１，２が初期の位置から反時計回り方向へ７５°回転する（図１４（ｂ）参照）。 Next, when the motor 6d rotates 240 ° counterclockwise from the initial state, the large gear 6c rotates 28 ° clockwise from the initial position, and accordingly, the contact pieces 1 and 2 move from the initial position. It rotates 75 ° counterclockwise (see FIG. 14B).

このとき、一方の接触片１は、押圧部１ｄ付近が舎利玉１０の進行方向前側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動し、また、他方の接触片２は、押圧部２ｄ付近が舎利玉１０の進行方向後側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動する（図１４（ａ）参照）。 At this time, one contact piece 1 moves while contacting the curved surface via the laver 11 so that the vicinity of the pressing portion 1d follows the curved surface on the front side in the traveling direction of the rice ball 10, and the other contact piece 2 Moves while contacting the curved surface through the laver 11 so that the vicinity of the pressing portion 2d traces the curved surface on the rear side in the traveling direction of the rice ball 10 (see FIG. 14A).

次に、モータ６ｄが初期状態から反時計回り方向へ２７３°回転したときには、大歯車６ｃが初期の位置から時計回り方向へ３６°回転し、それに伴い各接触片１，２が初期の位置から反時計回り方向へ９８°回転する（図１５（ｂ）参照）。 Next, when the motor 6d rotates 273 ° in the counterclockwise direction from the initial state, the large gear 6c rotates 36 ° in the clockwise direction from the initial position, and accordingly, the contact pieces 1 and 2 move from the initial position. It rotates 98 ° counterclockwise (see FIG. 15B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分に食い込んで当該部分を強く押圧し、また、第１接触面１ｂが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１５（ａ）参照）。また、他方の接触片２は、押圧部２ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄに食い込んで当該部分Ｄを強く押圧し、また、第２接触面２ｃが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１５（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d bites into the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building stone 10 and strongly presses the portion, and the first contact surface 1 b is formed on the building plate. The laver 11 is brought into contact with the 10 flat surface through the laver 11 and pressed against the surface (see FIG. 15A). In the other contact piece 2, the pressing portion 2d bites into the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building ball 10, and strongly presses the portion D, and the second contact surface 2c The laver 11 is brought into contact with the flat surface of the rice ball 10 via the nori 11 and pressed against the surface (see FIG. 15A).

次に、モータ６ｄが初期状態から反時計回り方向へ３１８°回転したときには、大歯車６ｃが反時計回り方向へ回転し、つまり再び逆転して、初期の位置から時計回り方向への回転角度が２４°となり、それに伴い各接触片１，２が時計回り方向へ回転し、つまり再び逆転して、初期の位置から反時計回り方向への回転角度が６４°になる（図１６（ｂ）参照）。 Next, when the motor 6d rotates 318 ° in the counterclockwise direction from the initial state, the large gear 6c rotates in the counterclockwise direction, that is, reversely rotates again, and the rotation angle from the initial position to the clockwise direction is increased. Accordingly, the contact pieces 1 and 2 rotate clockwise, that is, reversely rotate again, and the rotation angle from the initial position to the counterclockwise direction becomes 64 ° (see FIG. 16B). ).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分を押圧しているが、第１接触面１ｂは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図１６（ａ）参照）。また、他方の接触片２も、押圧部２ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄを押圧しているが、第２接触面２ｃは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図１６（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d presses the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building stone 10, but the first contact surface 1 b is on the flat surface of the building glass 10. It leaves | separates from the pasted seaweed 11 (refer Fig.16 (a)). Further, in the other contact piece 2, the pressing portion 2 d presses the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building stone 10, but the second contact surface 2 c is the flat surface of the building glass 10. It leaves | separates from the seaweed 11 affixed on (refer Fig.16 (a)).

本実施例では、上記したように、海苔１１の剥離を防止する上で重要な部分、すなわち、舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄを、押圧部１ｄ，２ｄにより、強く押圧することができるため、海苔１１の剥離をさらに生じ難くすることができ、さらに、該押圧部１ｄ，２ｄにより、当該部分Ｄを、比較的長時間強く押圧し続けることができるため、海苔１１の剥離をより生じ難くすることができる。 In the present embodiment, as described above, an important portion for preventing the laver 11 from peeling, that is, a boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the rice ball 10 is defined as the pressing portions 1d and 2d. Since the laver 11 can be strongly pressed, it is possible to further prevent the laver 11 from peeling off, and further, the pressing portion 1d, 2d can keep pressing the portion D strongly for a relatively long time. Further, peeling of the seaweed 11 can be made more difficult to occur.

次に、モータ６ｄが初期状態から反時計回り方向へ３６０°回転したときには、大歯車６ｃが反時計回り方向へ回転して、初期の位置に復帰し、それに伴い各接触片１，２が時計回り方向へ回転して、初期の位置に復帰する。そして、以上の動作により、舎利玉１０に対する海苔１１の巻き付けが終了し、海苔１１が巻き付けられた舎利玉１０は次工程へ移送される。このとき、各接触片１，２と海苔１１が巻き付けられた舎利玉１０との間には隙間が存在するため、各接触片１，２を左右にスライドさせなくても、各接触片１，２が舎利玉１０の移送の妨げとなることがない。 Next, when the motor 6d rotates 360 ° counterclockwise from the initial state, the large gear 6c rotates counterclockwise and returns to the initial position. Rotate in the turning direction and return to the initial position. And by the above operation | movement, the winding of the laver 11 around the rice cake 10 is completed, and the rice cake 10 around which the seaweed 11 is wound is transferred to the next process. At this time, since there is a gap between the contact pieces 1 and 2 and the bowl 10 around which the laver 11 is wound, the contact pieces 1 and 1 can be obtained without sliding the contact pieces 1 and 2 left and right. 2 does not hinder the transfer of the rice 10.

また、本実施例によれば、上記したように構造が簡素で、かつ海苔１１を巻き付ける動作が単純であり、さらに、上記したように、１個の舎利玉１０に海苔１１を巻き付ける間に、モータ６ｄは一方向にのみ回転すればよく、モータ６ｄを逆転させる必要がないため、従来の装置と比較して、生産速度を格段に速くすることが可能である。また、各接触片１，２が、上記所定の動作を行うため、舎利玉１０に海苔１１を巻き付けているときに舎利玉１０が倒れることがなく、舎利玉１０に対して海苔１１を素早く巻き付けることができる。 Further, according to the present embodiment, the structure is simple as described above, and the operation of winding the seaweed 11 is simple. Further, as described above, while the seaweed 11 is wound around the single rice ball 10, Since the motor 6d only needs to rotate in one direction and it is not necessary to reverse the motor 6d, the production speed can be remarkably increased as compared with the conventional apparatus. Moreover, since each contact piece 1 and 2 performs the said predetermined | prescribed operation | movement, when the laver 11 is wound around the sardine ball 10, the sardine ball 10 does not fall down, and the laver 11 is quickly wound around the sardine ball 10. be able to.

因みに、本実施例に係る海苔巻き付け装置によれば、舎利玉１０に海苔１１を巻き付けることができる１時間当たりの個数を、約４０００個（約６６個／分、従来比：約２培）にすることが可能である。 By the way, according to the laver wrapping apparatus according to the present embodiment, the number of hourly laver 11 that can be wound around the shrimp ball 10 is about 4000 pieces (about 66 pieces / minute, conventional ratio: about 2 cultures). Is possible.

また、本実施例で採用したリンク機構７は、調節機構８を有するため、該調節機構８により、アーム７ｂとの連結部における回転中心Ｅと大歯車６ｃの回転中心Ｆとの間の距離Ｌを調節することによって、各接触片１，２が回転し得る角度範囲を変化させることができる。すなわち、調節機構８により、各回転中心Ｅ，Ｆ間の距離Ｌを小さくすれば、各接触片１，２の最大回転角度を大きくすることができ、逆に、各回転中心Ｅ，Ｆ間の距離Ｌを大きくすれば、各接触片１，２の最大回転角度を小さくすることができる。従って、各接触片１，２の最大回転角度付近において、各接触片１，２が海苔１１を押圧する強さを調節することが可能となり、また、舎利玉１０の寸法変更に対応して各接触片１，２の回転角度を変更することも可能となる。 Further, since the link mechanism 7 employed in the present embodiment has the adjusting mechanism 8, the distance L between the rotation center E and the rotation center F of the large gear 6c at the connecting portion with the arm 7b is adjusted by the adjusting mechanism 8. By adjusting the angle, the angle range in which the contact pieces 1 and 2 can rotate can be changed. That is, if the distance L between the rotation centers E and F is reduced by the adjusting mechanism 8, the maximum rotation angle of the contact pieces 1 and 2 can be increased, and conversely between the rotation centers E and F. If the distance L is increased, the maximum rotation angle of each contact piece 1, 2 can be reduced. Therefore, it is possible to adjust the strength with which each contact piece 1, 2 presses the laver 11 in the vicinity of the maximum rotation angle of each contact piece 1, 2. It is also possible to change the rotation angle of the contact pieces 1 and 2.

本実施例に係る海苔巻き付け装置は、図１７（ｂ）に示したように、大歯車６ｃに代えてラック６ｅを用いる点で、実施例１に係る海苔巻き付け装置と異なる。 The laver wrapping apparatus according to the present embodiment is different from the laver wrapping apparatus according to the first embodiment in that a rack 6e is used instead of the large gear 6c, as shown in FIG.

ラック６ｅは、各回転軸３，４に設けられる２つの小歯車６ａ，６ｂの双方に噛み合うように設けられる。ラック６ｅとモータ６ｄとの間には、モータ６ｄの軸が一回転する間にラック６ｅを往復運動させるリンク機構７が設けられており、該リンク機構７は、モータ６ｄの軸に連結されるロータ７ａと、一端がロータ７ａに回転自在に連結され、他端がラック６ｅに回転自在に連結されるアーム７ｂとを有して構成される。 The rack 6e is provided so as to mesh with both of the two small gears 6a and 6b provided on the rotary shafts 3 and 4, respectively. A link mechanism 7 is provided between the rack 6e and the motor 6d to reciprocate the rack 6e while the shaft of the motor 6d rotates once. The link mechanism 7 is connected to the shaft of the motor 6d. The rotor 7a and an arm 7b having one end rotatably connected to the rotor 7a and the other end rotatably connected to the rack 6e are configured.

上記のように構成される海苔巻き付け装置は、以下のように動作する。すなわち、まず、舎利玉１０が海苔１１を巻き付ける位置に停止したときには、各接触片１，２の長手方向と舎利玉１０の進行方向とが略平行になるように、各接触片１，２が存する（図１７（ａ）及び図１７（ｂ）参照）。 The laver wrapping apparatus configured as described above operates as follows. That is, first, when the steak ball 10 stops at the position where the laver 11 is wound, the contact pieces 1, 2 are arranged so that the longitudinal direction of the contact pieces 1, 2 and the traveling direction of the steak ball 10 are substantially parallel. (See FIG. 17 (a) and FIG. 17 (b)).

次に、モータ６ｄが初期状態（回転角度が０°の状態）から反時計回り方向へ４２°回転したときには、モータ６ｄにリンク機構７を介して連結されたラック６ｅが初期の位置から一方向へ１６ｍｍ移動し、それに伴い各接触片１，２が初期の位置から時計回り方向へ７１°回転する（図１８（ｂ）参照）。 Next, when the motor 6d rotates 42 ° counterclockwise from the initial state (rotation angle is 0 °), the rack 6e connected to the motor 6d via the link mechanism 7 is unidirectional from the initial position. Accordingly, the contact pieces 1 and 2 rotate 71 ° clockwise from the initial position (see FIG. 18B).

このとき、一方の接触片１は、押圧部１ｄ付近が舎利玉１０の進行方向後側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動し、また、他方の接触片２は、押圧部２ｄ付近が舎利玉１０の進行方向前側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動する（図１８（ａ）参照）。 At this time, one contact piece 1 moves while contacting the curved surface via the laver 11 so that the vicinity of the pressing portion 1d traces the curved surface on the rear side in the direction of travel of the rice ball 10, and the other contact piece 2 moves while contacting the curved surface through the laver 11 so that the vicinity of the pressing portion 2d follows the curved surface on the front side in the traveling direction of the bowl 10 (see FIG. 18A).

次に、モータ６ｄが初期状態から反時計回り方向へ７９°回転したときには、ラック６ｅが初期の位置から一方向へ２２ｍｍ移動し、それに伴い各接触片１，２が初期の位置から時計回り方向へ９９°回転する（図１９（ｂ）参照）。 Next, when the motor 6d rotates 79 ° counterclockwise from the initial state, the rack 6e moves 22 mm in one direction from the initial position, and accordingly, the contact pieces 1 and 2 move clockwise from the initial position. Rotate 99 ° (see FIG. 19B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄに食い込んで当該部分Ｄを強く押圧し、また、第２接触面１ｃが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１９（ａ）参照）。また、他方の接触片２は、押圧部２ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分に食い込んで当該部分を強く押圧し、また、第１接触面２ｂが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図１９（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1d bites into the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building ball 10, and strongly presses the portion D, and the second contact surface 1c. However, the nori 11 is brought into contact with the flat surface of the rice ball 10 via the nori 11 and the nori 11 is pressed against the surface (see FIG. 19A). In the other contact piece 2, the pressing portion 2 d bites into the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building ball 10 and strongly presses the portion, and the first contact surface 2 b has the building block 10. The nori 11 is brought into contact with the flat surface through the laver 11 and pressed against the surface (see FIG. 19A).

次に、モータ６ｄが初期状態から反時計回り方向へ１０９°回転したときには、ラック６ｅが逆方向へ移動し、初期の位置から一方向への移動距離が１８ｍｍとなり、それに伴い各接触片１，２が反時計回り方向へ回転し、つまり逆転して、初期の位置から時計回り方向への回転角度が８０°になる（図２０（ｂ）参照）。 Next, when the motor 6d rotates counterclockwise by 109 ° from the initial state, the rack 6e moves in the reverse direction, and the moving distance in one direction from the initial position becomes 18 mm. 2 rotates counterclockwise, that is, reverses, and the rotation angle in the clockwise direction from the initial position becomes 80 ° (see FIG. 20B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄを押圧しているが、第２接触面１ｃは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図２０（ａ）参照）。また、他方の接触片２も、押圧部２ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分を押圧しているが、第１接触面２ｂは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図２０（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d presses the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building stone 10, but the second contact surface 1 c is the flat surface of the building glass 10. It leaves | separates from the seaweed 11 affixed on the surface (refer Fig.20 (a)). Further, in the other contact piece 2, the pressing portion 2 d presses the boundary portion between the curved surface and the flat surface on the front side in the direction of travel of the building stone 10, but the first contact surface 2 b is attached to the flat surface of the building glass 10. It leaves | separates from the attached nori 11 (refer Fig.20 (a)).

次に、モータ６ｄが初期状態から反時計回り方向へ１５９°回転したときには、ラック６ｅが逆方向へ移動して、ほぼ初期の位置に復帰し、それに伴い各接触片１，２が反時計回り方向へ回転して、ほぼ初期の位置に復帰する（図２１（ａ）及び図２１（ｂ）参照）。 Next, when the motor 6d rotates 159 ° counterclockwise from the initial state, the rack 6e moves in the reverse direction and returns to the almost initial position, and the contact pieces 1 and 2 are rotated counterclockwise accordingly. Rotate in the direction and return to the almost initial position (see FIGS. 21A and 21B).

次に、モータ６ｄが初期状態から反時計回り方向へ１８０°回転した後さらに同じ方向へ３５°回転したときには、ラック６ｅが初期の位置から逆方向へ１８ｍｍ移動し、それに伴い各接触片１，２が初期の位置から反時計回り方向へ７９°回転する（図２２（ｂ）参照）。 Next, when the motor 6d rotates 180 ° counterclockwise from the initial state and then further rotates 35 ° in the same direction, the rack 6e moves 18 mm in the reverse direction from the initial position, and accordingly, each contact piece 1, 2 rotates 79 ° counterclockwise from the initial position (see FIG. 22B).

このとき、一方の接触片１は、押圧部１ｄ付近が舎利玉１０の進行方向前側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動し、また、他方の接触片２は、押圧部２ｄ付近が舎利玉１０の進行方向後側の曲面をなぞるように、該曲面に海苔１１を介して接触しつつ移動する（図２２（ａ）参照）。 At this time, one contact piece 1 moves while contacting the curved surface via the laver 11 so that the vicinity of the pressing portion 1d follows the curved surface on the front side in the traveling direction of the rice ball 10, and the other contact piece 2 Moves while contacting the curved surface via the laver 11 so that the vicinity of the pressing portion 2d traces the curved surface on the rear side in the traveling direction of the bowl 10 (see FIG. 22A).

次に、モータ６ｄが初期状態から反時計回り方向へ１８０°回転した後さらに同じ方向へ７９°回転したときには、ラック６ｅが初期の位置から逆方向へ２２ｍｍ移動し、それに伴い各接触片１，２が初期の位置から反時計回り方向へ９８°回転する（図２３（ｂ）参照）。 Next, when the motor 6d is rotated 180 ° counterclockwise from the initial state and then further rotated 79 ° in the same direction, the rack 6e is moved 22 mm from the initial position in the reverse direction. 2 rotates 98 ° counterclockwise from the initial position (see FIG. 23B).

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分に食い込んで当該部分を強く押圧し、また、第１接触面１ｂが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図２３（ａ）参照）。また、他方の接触片２は、押圧部２ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄに食い込んで当該部分Ｄを強く押圧し、また、第２接触面２ｃが舎利玉１０の平坦面に海苔１１を介して接触して当該面に海苔１１を押し付ける（図２３（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d bites into the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building stone 10 and strongly presses the portion, and the first contact surface 1 b is formed on the building plate. The laver 11 is brought into contact with the flat surface 10 through the laver 11 and pressed against the surface (see FIG. 23A). In the other contact piece 2, the pressing portion 2d bites into the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building ball 10, and strongly presses the portion D, and the second contact surface 2c The laver 11 is brought into contact with the flat surface of the rice ball 10 via the nori 11 and pressed against the surface (see FIG. 23A).

次に、モータ６ｄが初期状態から反時計回り方向へ１８０°回転した後さらに同じ方向へ１３２°回転したときには、ラック６ｅが一方向へ移動して、初期の位置から逆方向への移動距離が１６ｍｍとなり、それに伴い各接触片１，２が時計回り方向へ回転し、つまり再び逆転して、初期の位置から反時計回り方向への回転角度が７２°になる（図２４（ｂ）参照）。 Next, when the motor 6d rotates 180 ° counterclockwise from the initial state and then further rotates 132 ° in the same direction, the rack 6e moves in one direction, and the moving distance in the reverse direction from the initial position is increased. Accordingly, the contact pieces 1 and 2 rotate in the clockwise direction, that is, reversely rotate again, and the rotation angle from the initial position to the counterclockwise direction becomes 72 ° (see FIG. 24B). .

このとき、一方の接触片１は、押圧部１ｄが舎利玉１０の進行方向前側における曲面と平坦面との境界部分を押圧しているが、第１接触面１ｂは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図２４（ａ）参照）。また、他方の接触片２も、押圧部２ｄが舎利玉１０の進行方向後側における曲面と平坦面との境界部分Ｄを押圧しているが、第２接触面２ｃは舎利玉１０の平坦面に貼り付けられた海苔１１から離れる（図２４（ａ）参照）。 At this time, in the one contact piece 1, the pressing portion 1 d presses the boundary portion between the curved surface and the flat surface on the front side in the traveling direction of the building stone 10, but the first contact surface 1 b is on the flat surface of the building glass 10. It leaves | separates from the pasted seaweed 11 (refer Fig.24 (a)). Further, in the other contact piece 2, the pressing portion 2 d presses the boundary portion D between the curved surface and the flat surface on the rear side in the traveling direction of the building stone 10, but the second contact surface 2 c is the flat surface of the building glass 10. It leaves | separates from the nori 11 stuck on (refer Fig.24 (a)).

次に、モータ６ｄが初期状態から反時計回り方向へ３６０°回転したときには、ラック６ｅが一方向へ移動して、初期の位置に復帰し、それに伴い各接触片１，２が時計回り方向へ回転して、初期の位置に復帰する。そして、以上の動作により、舎利玉１０に対する海苔１１の巻き付けが終了する。 Next, when the motor 6d rotates 360 ° counterclockwise from the initial state, the rack 6e moves in one direction and returns to the initial position, and accordingly, the contact pieces 1 and 2 move in the clockwise direction. Rotates and returns to the initial position. And the winding of the laver 11 to the rice cake 10 is complete | finished by the above operation | movement.

以上説明したように、本実施例に係る海苔巻き付け装置も、実施例１に係る海苔巻き付け装置と同様に、構造が簡素で、かつ海苔１１を巻き付ける動作が単純であり、さらに、上記したように、１個の舎利玉１０に海苔１１を巻き付ける間に、モータ６ｄは一方向にのみ回転すればよく、モータ６ｄを逆転させる必要がないため、従来の装置と比較して、生産速度を格段に速くすることが可能である。 As described above, the laver wrapping apparatus according to the present embodiment also has a simple structure and a simple operation of winding the laver 11 as in the laver wrapping apparatus according to the first embodiment. While the laver 11 is wound around the single rice ball 10, the motor 6 d only needs to rotate in one direction, and it is not necessary to reverse the motor 6 d, so that the production speed is significantly higher than that of the conventional apparatus. It can be fast.
