Description

本発明は、握飯をシート状フィルムによって自動包装する握飯包装装置に関するものである。   The present invention relates to a rice cracking packaging device for automatically packaging rice by a sheet-like film.

従来、三角形握飯の自動包装装置は、飯塊を三角形状の型に挿入することで三角形状握飯を成形し、その後海苔を内包したシート状フィルムによって三角形握飯を自動包装する装置が開発されている（特許文献１等）。   Conventionally, an automatic packaging device for triangular rice cracking has been developed in which a triangular rice cake is formed by inserting a lump of rice into a triangular mold, and then the triangular rice cooking is automatically packaged with a sheet-like film containing laver. (Patent Document 1 etc.).

この種の自動包装装置において包装される握飯は、包装の過程で三角形状の雌型に押込まれるため、三角形状握飯の上下左右の各縁部が比較的鋭角的な形状となる。   In this type of automatic wrapping apparatus, the rice grinds to be packaged are pushed into a triangular female mold during the packaging process, so that the upper, lower, left and right edges of the triangular rice grind have a relatively acute shape.

特許第３３９６１９２号公報Japanese Patent No. 3396192

ところで、近年の握飯の多品種化の流れ、市場の要望等によると、自動包装装置によって形成される握飯に対して、より手作りに近い形状の握飯とすることが望まれている。   By the way, according to the recent trend of increasing the variety of handmade rice, market demands, etc., it is desired to make the handmade rice closer to a handmade shape than the rice produced by the automatic packaging device.

しかしながら、従来の自動包装装置では三角形状成形型に押込まれる段階を経るため、握飯の縁部等を丸めたような手作り感覚に近い形状を維持したままでの包装が難しいという課題がある。   However, since the conventional automatic packaging apparatus passes through the step of being pushed into the triangular mold, there is a problem that it is difficult to perform packaging while maintaining a shape close to a handmade feeling such as a rounded edge of a rice ball.

そこで、本発明は、より手作り感覚に近い形状の三角形握飯を当該形状を保持したまま自動包装し得る握飯包装装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a rice sachet packaging device that can automatically wrap a triangular rice cooker having a shape closer to a handmade feeling while maintaining the shape.

Then, the grooves 37a and 37b move outward in the radial direction, and accordingly, the two rice catching plates 23 and 23 (the rice catching plates 23f and 23g in FIG. 9) at the fifth stop position Z ″ are also intermittently wound. In order to move outward in the radial direction with respect to the moving plate 16, the two concave arc-shaped receiving portions 26 a and 26 a that protrude into the packaging female mold 17 positioned at the fifth stop position Z ″ are thereby each radiused. It slides outward in the direction, and the concave arc-shaped receiving portions 26a, 26a are retracted and accommodated below the intermittent rotation disk 16 (state of FIGS. 2 and 10). At this time, the taper portions 26b and 26b slightly protrude inside the packaging female mold 17 (see FIG. 10).

これにより、包装用雌型内１７内の握飯１は下方の支持を略失った状態となる。尚、このときの上記嵌合溝部３７の半径方向外方への摺動距離は、上記握飯受板２３の外周面２３ｄが上記間歇回動円盤１６の外周面に略一致する位置までの範囲とする。   Thereby, the rice cooker 1 in the female mold 17 for packaging is in a state where the lower support is substantially lost. The sliding distance of the fitting groove portion 37 in the radial direction at this time is a range from the outer peripheral surface 23d of the rice catching plate 23 to a position where it substantially coincides with the outer peripheral surface of the intermittent rotation disk 16. To do.

そして、上記凹弧状受部２６ａ，２６ａが引き込み収容されたタイミングで（図１０）、直立中心線ｅを通る上下方向昇降軸２２ａに設けた水平腕４１の先端下向きに設けた取卸用スタンプ４０（図２、図１９）を下降させることにより、上記包装された握飯１は上記取卸用透孔３５から下方に取卸される（図２、図１０）。   Then, at the timing when the concave arc-shaped receiving portions 26a, 26a are retracted and accommodated (FIG. 10), the unloading stamp 40 provided downward on the tip of the horizontal arm 41 provided on the vertical elevating shaft 22a passing through the upright center line e. By lowering (FIGS. 2 and 19), the wrapped rice ball 1 is unloaded downward from the unloading through-hole 35 (FIGS. 2 and 10).

その後は、上記駆動腕３９を持って上記摺動腕３６と嵌合溝部３７を復動させ（矢印ｍ方向）、これにより上記嵌合溝部３７の溝部３７ａ，３７ｂを上記円形溝２７ａに連通させ上記凹弧状受部２６ａ，２６ａを上記臨出状態に戻し（図９の状態）、その後のタイミングで間歇回動円盤１６を間歇回動させる。   Thereafter, holding the drive arm 39, the sliding arm 36 and the fitting groove 37 are moved backward (in the direction of the arrow m), thereby causing the grooves 37a and 37b of the fitting groove 37 to communicate with the circular groove 27a. The concave arc receiving portions 26a, 26a are returned to the projecting state (the state shown in FIG. 9), and the intermittent rotation disk 16 is intermittently rotated at the subsequent timing.

An upright support pipe 50 is provided on the upper part of the machine frame F, a fixed support board 27 is supported on the support pipe 50, and the rotating and rotating disk 16 is supported thereon. The rotation drive shaft 22b of the intermittent rotation disk 16 is provided with an intermediate rotation cam 52 having a plurality of U-shaped notches 52a formed at the lower end thereof through the central through hole of the fixed support disk 27 and inserted into the bearing 51. The upward pin 54 provided on the upright continuous rotation shaft 53 continuously rotates and sequentially enters the U-shaped notch 52a, and intermittently rotates the intermittent rotation cam 52 every 60 degrees, so that the intermediate portion of the adjacent U-shaped notch 52a The operation of rotating the cam 52 to stop the cam 52 is repeated, whereby the disk 16 is intermittently rotated every 60 degrees. The raising / lowering operation of the push stamps 18 and 40 is performed by extending the raising / lowering shaft 22a downward through the upright support pipe 50 and connecting it to a crank mechanism 56 provided on the horizontal continuous rotating shaft 55. The raising / lowering operation can be realized by the rotation of 55. By transmitting the rotation of the horizontal continuous rotation shaft 55 to the upright continuous rotation shaft 53 through the bevel gear 57, the intermittent rotation and the lifting operation can be linked. M is a drive motor for the rotary shaft 55.

上記摺動腕３６及び嵌合溝部３７の半径方向の摺動動作は、図１８に示すように上記昇降軸２２ａの昇降動作に連動して昇降する他の昇降軸２２ａ’を設け、かつ該昇降軸２２ａ’の昇降に応じて昇降する昇降杆６０、該昇降杆６０端部に一端を軸支され中心軸６２を中心とする回動運動を行う回動腕６３、該回動腕６３にピン６４で接続され水平杆６５の一端に軸着されて該水平杆６５を駆動する駆動腕６６、機枠Ｆの水平アングルＦ’に軸支６５’され上記駆動腕６６の駆動により上記軸６５’を中心とする水平回動運動を行う水平杆６５を設け、これらの部材により上記昇降軸２２ａ’の昇降運動を上記水平杆６５の水平回動運動に変換するリンク機構を構成し、上記水平杆６５の他端に上記駆動腕３９の他端３９’を軸支する。かかる構成により、上記昇降軸２２ａ’の昇降動作を上記摺動腕３６及び嵌合溝部３７の半径方向の往復摺動動作に変換することができる。そして、上記取卸スタンプ４０が下降するタイミングで上記嵌合溝部３７を半径方向（矢印ｋ方向）に摺動させ、上記凹弧状受部２６ａ，２６ａを上記第５停止位置Ｚ”に停止した上記雌型１７下部に臨出した状態から引き込み状態とし、上記スタンプ４０の押込みにより取卸し可能とし、上記取卸スタンプ４０が上昇するタイミングで上記嵌合溝部３７を半径方向に復動させ（矢印ｍ方向）、上記溝部３７ａ，３７ｂを上記円形溝部２７ａの切欠部２７ａ’，２７ａ“に嵌合させるように構成すれば良い。   The sliding movement in the radial direction of the sliding arm 36 and the fitting groove 37 is provided with another lifting shaft 22a 'that moves up and down in conjunction with the lifting operation of the lifting shaft 22a as shown in FIG. A lifting rod 60 that moves up and down in accordance with the lifting and lowering of the shaft 22 a ′, a rotating arm 63 that is pivotally supported around one end of the lifting rod 60 and pivoting about the central shaft 62, and a pin 64, connected to one end of a horizontal rod 65 to drive the horizontal rod 65, and is supported by a horizontal angle F ′ of the machine frame F. The shaft 65 ′ is driven by the drive arm 66. A horizontal rod 65 that performs a horizontal rotation movement around the horizontal rod 65 is provided, and by these members, a link mechanism that converts the vertical movement of the lifting shaft 22a ′ into a horizontal rotation motion of the horizontal rod 65 is configured. The other end 39 ′ of the drive arm 39 is pivotally supported on the other end of 65. With this configuration, the lifting operation of the lifting shaft 22 a ′ can be converted into a reciprocating sliding operation in the radial direction of the sliding arm 36 and the fitting groove portion 37. Then, when the unloading stamp 40 descends, the fitting groove 37 is slid in the radial direction (arrow k direction), and the concave arc receiving portions 26a and 26a are stopped at the fifth stop position Z ″. The state where the female mold 17 protrudes is changed to the retracted state and can be unloaded by pushing the stamp 40, and the fitting groove 37 is moved back in the radial direction at the timing when the unloading stamp 40 is raised (arrow m). Direction), the groove portions 37a and 37b may be configured to fit into the cutout portions 27a 'and 27a "of the circular groove portion 27a.

次に、本発明に係る握飯成形装置の動作を説明する。   Next, the operation of the rice cracking forming apparatus according to the present invention will be described.

間歇回動円盤２の間歇回動により、三角形雌型２’内の握飯１が固定円盤３の透孔３’に位置すると（図３（イ）のタイミング）、間歇押上雄型５が中心線ｎ上を上昇し握飯１を固定雌型９の上方まで押し上げる（図３（ロ）の位置）。このとき、コンベヤ７，７の上記雌型２’上に長方形包装用シート状フィルム６が位置しているため、上記上昇により握飯１にはその上面から上記フィルム６が被覆された状態（図５（ロ）の状態）となる。   When the handle 1 in the triangular female mold 2 ′ is positioned in the through hole 3 ′ of the fixed disk 3 by the intermittent rotation of the intermittent rotation disk 2 (timing in FIG. 3 (a)), the intermittent push-up male mold 5 is the center line. n is raised and the rice grind 1 is pushed up above the fixed female die 9 (position (b) in FIG. 3). At this time, since the rectangular packaging sheet-like film 6 is positioned on the female mold 2 'of the conveyors 7 and 7, the rice 6 is covered with the film 6 from the upper surface by the ascent (FIG. 5). (B) state).

次に、上記水平腕１３が水平回動することにより外端Ｖ字溝形押板１１が矢印ｂ方向に摺動し、これにより上記握飯１は対称中心線ｒを移動して間歇回動円盤１６の包装用雌型１７の上方位置まで移動する（図３（ハ）の位置）。このとき、上記押形１１のＶ字溝が上記握飯１の側面１ｅ，１ｅに当接した状態で握飯１を移動させるため、上記フィルム６は上記側面１ｅ，１ｅに接触すると共に、上記握飯１の下面１ｄ側にフィルム６が折り込まれて図５（ハ）に示す状態となる（第１の停止位置Ｘ）。   Next, when the horizontal arm 13 rotates horizontally, the outer end V-shaped grooved pressing plate 11 slides in the direction of the arrow b, whereby the rice grinder 1 moves along the symmetrical center line r, thereby causing an intermittent rotation disk. It moves to the upper position of 16 packaging female molds 17 (position of FIG. 3 (c)). At this time, since the rice grind 1 is moved in a state in which the V-shaped groove of the pressing shape 11 is in contact with the side surfaces 1e, 1e of the rice grind 1, the film 6 is in contact with the side surfaces 1e, 1e and the rice grab 1 The film 6 is folded on the lower surface 1d side of the film to be in the state shown in FIG. 5C (first stop position X).

このタイミングで昇降軸２２ａの下降動作により押込スタンプ１８が下降して、上記握飯１を間歇回動円盤１６の第１の停止位置Ｘに位置する包装用雌型１７内に押込む。このとき、上記押込スタンプ１８下面は凹状湾曲面１８ｂとなっているので、握飯１の上面の凸状湾曲面を押しつぶすこともない。さらに、当該包装用雌型１７の下面側には握飯受板２３，２３の凹弧状受面２６ａ，２６ａが臨出しているので（図２参照）、上記押込まれた握飯１の下側左右縁部１ｂ，１ｂもその湾曲状態を維持し得るし、さらに握飯１の下面１ｄの凸状湾曲面も押し潰されることはない（図１１参照）。この時点において、握飯１のフィルム６は上記包装用雌型１７に押込まれることにより起立フィルム６ｂ、６ｂ’の形成された図５（ニ）の状態となる。   At this timing, the pushing stamp 18 is lowered by the lowering operation of the elevating shaft 22a, and the rice cooker 1 is pushed into the packaging female die 17 located at the first stop position X of the intermittent rotation disk 16. At this time, since the lower surface of the pressing stamp 18 is a concave curved surface 18b, the convex curved surface on the upper surface of the rice cooker 1 is not crushed. Furthermore, since the concave receiving surfaces 26a, 26a of the rice catching plates 23, 23 are exposed on the lower surface side of the packaging female die 17 (see FIG. 2), the lower left and right edges of the pushed rice catching rice 1 The portions 1b and 1b can also maintain the curved state, and the convex curved surface of the lower surface 1d of the rice grind 1 is not crushed (see FIG. 11). At this point of time, the film 6 of the rice bran 1 is pushed into the packaging female die 17 so that the upright films 6b and 6b 'are formed as shown in FIG.

その後上記押込スタンプ１８が上昇した後のタイミングで、上記間歇回動円盤１６は矢印ｄ方向に回動して第２停止位置Ｙに停止する。そして、往復回動腕２８が矢印ｉ方向に往動すると共にローラ３４が押込まれて摺動案内板３１が矢印ｊ方向に回動することにより、上記往復回動腕２８の往動により一方の起立フィルム６ｂが折り畳まれ、その後加熱棒によって熱溶着６’される（図５（ホ）の位置）。そして、上記往復回動腕２８の復動によって発条３３により上記摺動案内板３１が復動することにより、他方の起立フィルム６ｂ’が折り畳まれる（図５（へ）の位置）。   Thereafter, at the timing after the pushing stamp 18 is raised, the intermittent rotation disk 16 rotates in the direction of the arrow d and stops at the second stop position Y. Then, the reciprocating arm 28 moves forward in the direction of the arrow i and the roller 34 is pushed and the sliding guide plate 31 rotates in the direction of the arrow j. The upright film 6b is folded and then heat-welded 6 'by a heating rod (position in FIG. 5 (e)). Then, when the reciprocating arm 28 is moved backward, the sliding guide plate 31 is moved back by the ridge 33, whereby the other upright film 6b 'is folded (position shown in FIG. 5).

そして、上記摺動案内板３１の復動後のタイミングで上記間歇回動円盤１６が第３の停止位置Ｚまで回動し、当該位置において折り畳まれたフィルム６が加熱棒によって熱溶着６’されて折込状態で固定される。   Then, the intermittent rotation disk 16 rotates to the third stop position Z at the timing after the backward movement of the sliding guide plate 31, and the film 6 folded at the position is heat-welded 6 'by the heating rod. And fixed in the folded state.

その後、上記間歇回動円盤１６が第４停止位置Ｚ’を経て第５停止位置Ｚ”に停止する。このとき、当該位置Ｚ”に位置する包装用雌型１７に臨出する握飯受板２３，２３の凹弧状受部２６ａ，２６ａのローラ２５，２５は各々嵌合溝部３７の溝部３７ａ，３７ｂ上に各々位置している（図９）。上記回動円盤１６が第５停止位置Ｚ”に停止したタイミングで、上記嵌合溝部３７を半径方向外方（矢印方向）に摺動し、これにより上記第５停止位置Ｚ”の上記握飯受板２３，２３が当該円盤１６の外方に移動する（図９から図１０の状態）。   Thereafter, the intermittent rotation disk 16 stops at the fifth stop position Z ″ through the fourth stop position Z ′. At this time, the rice catching plate 23 that protrudes to the female die 17 for packaging located at the position Z ″. , 23 are respectively positioned on the groove portions 37a, 37b of the fitting groove portion 37 (FIG. 9). At the timing when the rotating disk 16 stops at the fifth stop position Z ″, the fitting groove portion 37 is slid radially outward (in the direction of the arrow), whereby the rice catcher at the fifth stop position Z ″ is received. The plates 23 and 23 are moved outward from the disk 16 (states shown in FIGS. 9 to 10).

そして、上記受板２３，２３の凹弧状受部２６ａ，２６ａが第５停止位置Ｚ“にある包装用雌型１７内から円盤１６下面に引き込まれた状態で（図１０の状態）、昇降軸２２ａを下降させて取卸スタンプ４０を下降させ、上記包装用雌型１７内の握飯１を上記取卸用透孔３５を介して下方側に落下させ、当該包装された握飯１を取り卸すことができる。   In the state where the concave arc receiving portions 26a, 26a of the receiving plates 23, 23 are drawn into the lower surface of the disk 16 from the inside of the packaging female die 17 at the fifth stop position Z "(state of FIG. 10), the lifting shaft 22a is lowered, the unloading stamp 40 is lowered, and the rice cooker 1 in the packaging female die 17 is dropped to the lower side through the unloading through-hole 35, and the packaged rice noodle 1 is unloaded. Can do.

その後、上記嵌合溝部３７を矢印ｍ方向に摺動させて上記溝部３７ａ，３７ｂを上記円形溝２７ａに連通させる。これにより、上記２つの握飯受板２３，２３は上記回動円盤１６の半径方向内側に収納され、上記凹弧状受部２６ａ，２６ａが上記包装用雌型１７の下側に臨出した状態で、上記間歇回動円盤１６が矢印ｄ方向に間歇回動する。よって、当該包装用雌型１７が上記第１停止位置Ｘに到来したときは、当該位置の包装用雌型１７内には上記凹弧状受部２６ａ，２６ａが臨出しており（図２）、上記と同様の動作により握飯１の包装動作を行うことができる。   Thereafter, the fitting groove 37 is slid in the direction of the arrow m so that the grooves 37a and 37b communicate with the circular groove 27a. Thus, the two rice catching plates 23 and 23 are accommodated inside the rotating disk 16 in the radial direction, and the concave arc receiving portions 26a and 26a are exposed to the lower side of the female die 17 for packaging. The intermittent rotation disk 16 is intermittently rotated in the direction of the arrow d. Therefore, when the packaging female mold 17 arrives at the first stop position X, the concave arc-shaped receiving portions 26a, 26a protrude in the packaging female mold 17 at the position (FIG. 2). The packaging operation of the rice ball 1 can be performed by the same operation as described above.

以上のように本発明の握飯包装装置によれば、手作りに近い丸みのある形状の握飯１を、当該丸みのある形状を維持しながら自動的に包装することができる。また、握飯１の下方左右縁部１ｂ，１ｂや上方及び下方湾曲面１ｃ、１ｄ、さらに上方左右縁部１ａ，１ａも自動包装の過程で押し潰されること無く、丸みのある形状のまま、自動的に包装を行うことができるという効果がある。   As described above, according to the rice shaking packaging apparatus of the present invention, it is possible to automatically package the rice cooking 1 having a round shape that is close to handmade while maintaining the round shape. Further, the lower left and right edge portions 1b, 1b, the upper and lower curved surfaces 1c, 1d, and the upper left and right edge portions 1a, 1a of the rice ball 1 are automatically crushed without being crushed during the automatic packaging process. There is an effect that the packaging can be performed in an effective manner.
