Description
本発明は3角形握飯をシート状包装フィルムによって包装する分野に関するものである。 The present invention relates to the field of packaging triangular rice bran with a sheet-like packaging film.
従来、3角形包装握飯は長方形シート状包装フィルムで直立底辺上下面を被覆し、さらに直立両側面に沿って起立したフィルム片を上面のフィルム上に倒伏させて加熱棒で溶着した。 Conventionally, a triangular package rice bran has been coated with a rectangular sheet-like packaging film on the upper and lower surfaces of the upright base, and further, the film pieces erected along the both sides of the upright are laid down on the upper film and welded with a heating rod.
このように形成した3角形包装握飯は直立底辺の両端部分及び頂部にシート状包装フィルムによる嘴状突起が3方に折曲形成された。 The triangular package rice cooker formed in this way was formed with ridge-like projections formed by sheet-like packaging films in three directions at both ends and the top of the upright bottom.
上記3方の嘴状突起を溶着密封するため、包装機から3角形包装握飯を機外に取卸した後、包装機外に設けた密封機によって3方の嘴状突起を溶着密封する工程を必要とした(例えば特許文献1)。 In order to weld and seal the above-mentioned three-side hook-shaped projections, a process of welding and sealing the three-side hook-shaped projections with a sealing machine provided outside the packaging machine after unloading the triangular packaging rice from the packaging machine. Necessary (for example, Patent Document 1).
その後本願の発明書によって直立底辺の両端部の上記嘴状突起は上記包装機内において密着状態に折曲形成され溶着密封の必要がなくなった。 After that, according to the invention of the present application, the hook-like protrusions at both ends of the upright bottom are bent in a close contact state in the packaging machine, and the need for welding and sealing is eliminated.
しかし、頂部の嘴状突起は包装機外において狭圧加熱具によって、やはり加熱溶着する工程を必要とした(特許文献2)。 However, the ridge-like projections at the top part also required a process of heat welding with a narrow pressure heating tool outside the packaging machine (Patent Document 2).
本発明は握飯包装装置による3角形握飯包装工程において、
中心軸線の回りに間歇回動する包装用雌型の間歇停止時に頂部の嘴状突起を狭圧加熱溶着し、包装機外の上記加熱溶着工程を省略することを目的とする。
The present invention is a triangular rice cracking packaging process using a rice cracking packaging device,
An object of the present invention is to heat-weld the top ridge-like projections at the time of intermittent stop of the packaging female mold that rotates intermittently around the central axis, and to omit the above-described heat-welding step outside the packaging machine.
上記の目的を達成するため本発明は
第1に3角形握飯の包装用雌型を間歇回動自在に支持板上に設け、上記包装用雌型の対称中心線が間歇回動のラジアル方向線であって、上記包装用雌型の底辺の両端及び頂部に包装フィルムによる嘴状突起挿入溝を設けてなる握飯包装機において、上記包装用雌型を間歇回動円板の外周に沿って均等開き角上に複数個穿設し、上記頂部が上記中心線に沿って該円板の外周に向い、上記円板と同心円で該円板の上面より低い外周部上面よりなる低段縁を頂部の上記挿入溝部に形成し、上記円板の間歇停止状態において上記円板の外側から上記低段縁上にある頂部の上記挿入溝内に保持される上記フィルムの嘴状突起に向って両側から対向方向に正逆回動する加熱具を設けてなる握飯包装機における頂部シール装置、
第2に上記対称中心線の両側対称位置にそれぞれ屈曲平行リンクを機枠に遊支し、上記リンクの外端を接続する平行杆のそれぞれ先端部に互に対向する加熱具を設けた上記第1発明記載の握飯包装機における頂部シール装置、
第3に上記屈曲平行リンクの内端を接続する動作用平行杆を長孔連杆で接続し、該連杆をエアシリンダーで往復動作し、それにより上記加熱具を対向方向に正逆回動させる上記第2発明記載の握飯包装機における頂部シール装置、
によって構成される。
In order to achieve the above object, the present invention firstly provides a female mold for packaging a triangular rice bran on a support plate so that it can rotate intermittently, and the symmetrical center line of the female mold for packaging is a radial direction line of intermittent rotation. In the rice grinder packaging machine in which the ridge-like protrusion insertion grooves by the wrapping film are provided at both ends and the top of the bottom of the wrapping female mold, the wrapping female mold is evenly distributed along the outer periphery of the intermittent rotation disk. A plurality of holes are formed on the opening angle, the top is directed to the outer periphery of the disk along the center line, and the lower step edge formed by the upper surface of the outer periphery that is concentric with the disk and lower than the upper surface of the disk is the top. In the insertion groove portion of the disk, in the intermittent stop state of the disk, from both sides toward the hook-shaped protrusion of the film held in the insertion groove on the top portion on the low step edge from the outside of the disk Top seal in a rice grinder packaging machine provided with a heating tool that rotates forward and backward in the opposite direction apparatus,
Secondly, the bending parallel links are freely supported on the machine frame at the symmetrical positions on both sides of the center line of symmetry, and the heating tools are provided which are opposed to the respective leading ends of the parallel rods connecting the outer ends of the links. 1 A top seal device in a rice cracking packaging machine according to the invention;
Thirdly, an operating parallel rod connecting the inner ends of the bent parallel links is connected by a long hole linkage, and the linkage is reciprocated by an air cylinder, thereby rotating the heating tool forward and backward in the opposite direction. top seal device in rice ball packaging machine above Symbol second invention according to,
Consists of.
従って間歇回動円板が間歇停止し、停止した上記雌型内の3角形包装握飯の頂部の包装フィルムによる嘴状突起は低段縁上に露出した状態である。 Therefore, the intermittent rotation disk stops intermittently, and the ridge-like projections by the packaging film at the top of the triangular packaging rice grind in the female mold stopped are exposed on the low step edge.
この露出状態の嘴状突起に向ってその両側から加熱具が対向圧着し、該突起を溶着した後、両加熱具は上記円板の外側に回動して間歇停止し、その状態で上記円板は次の停止位置に間歇回動し、上記包装握飯は機外に取卸される。 The heating tool is oppositely crimped from both sides toward the exposed hook-shaped protrusion, and the protrusions are welded. Then, both the heating tools rotate outwardly from the disk and stop intermittently. The board is intermittently rotated to the next stop position, and the packaged rice is taken out of the machine.
両加熱具はエアシリンダーの往復動作によって動作する対称位置の屈曲平行リンクによって、上記円板の外側から上記低段縁上に正逆回動することができる。 Both heating tools can be rotated forward and backward from the outer side of the disk onto the lower edge by a symmetrical parallel bent link that is operated by reciprocation of the air cylinder.
本発明は上述のように構成したので、
間歇回動円板の外周に沿って均等開き角上に穿設された3角形握飯包装用雌型内の包装フィルムによる既包装握飯の頂部の挿入溝内に形成された嘴状突起を、上記円板の間歇停止時に両側から加熱溶着した後さらに間歇回動してスタンプ等で上記包装握飯製品を機外に取卸し、機外において上記嘴状突起の加熱溶着工程を要しない効果がある。
Since the present invention is configured as described above,
The hook-shaped protrusion formed in the insertion groove at the top of the pre-packaged rice cooker by the packaging film in the female mold for triangular rice-cooking packaging, which is perforated on the uniform opening angle along the outer periphery of the intermittent rotation disc, After the disk is intermittently stopped, it is heated and welded from both sides, and is further rotated intermittently to take out the packaged rice products with a stamp or the like from the outside of the machine.
