Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a triangular rice ball packaging machine.

``Prior Art'' Conventionally, a rectangular seaweed sheet 33 is housed in a packaging sheet 23 made of a synthetic resin double film as shown in FIG. A product packaged using the procedure shown in the figure has been developed. However, since this packaging procedure is performed manually, there are problems in that it is difficult to improve work efficiency and it is difficult to mass-produce.

``Problems to be Solved by the Invention'' An object of the present invention is to carry out the above-mentioned packaging procedure for triangular rice grips using mechanical force, and to mass-produce packaged rice grips.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides a packaging sheet supply stand 28 in the machine frame 1, forms an approximately triangular rice-handling supply port 2 on the supply stand 28, and 2 is connected to the upper end of a substantially triangular cylinder 4 for lowering rice grips to form the same cylinder 4, and the upper surface of the rice gripper that goes in and out of the vertical inner plates 3, 3 adjacent to each other and descends inside the cylinder 4. A packaging sheet folding tool 6 that reciprocates toward the
6 is provided, a rice-grip-thickness gap 〓t is opened at the lower end of the cylinder 4, and a rice-grip cross-feeding guide plate 5 is provided to connect to the rice-grip thickness 〓t, and the rice-grip passes through the cylinder 4 through the above-mentioned gap 〓t. A rice grip lateral extrusion device 7 is provided, and a rice grip erecting device 8 for lateral extrusion rice grip is provided following the lateral conveying guide plate 5, and a rice grip storage pit 9 corresponding to the erecting device 8 is fitted into which the standing rice grip is inserted. An upright intermittent sliding plate 10 having
The rice grip packaging machine is provided with a movable folding plate 12 and a fixed folding plate 13 for the packaging sheet facing the bottom surface of the rice shaker on the outside of the entrance of the pit 9.

"Function" Therefore, the packaging sheet 23 is placed on the supply table 28, the triangular rice ball 11 is placed thereon, and the triangular tube 4 is fed from the supply port 2 by the cylinder 25.
When the inside is lowered, the sheet 23 is bent 90 degrees by the straight inner plates 3, 3, 3' of the cylinder 4, and covers three sides of the rice ball 11 (this state is shown in Fig. 12). ), and is placed on the cross-feeding guide plate 5. In this state, the sheet folding tools 6, 6 alternately go in and out, and the triangular piece 24 stands upright on two sides.
24 is folded onto the flat surface (upper surface) of the rice ball 11 as shown in FIG. After that, the lateral extrusion device 7
When the rice grip 11 slides in the direction of the arrow a in FIG.
Lay down on the 1st plane (upper surface). In this state, the rice bowl 11 is turned 90 degrees by the rice bowl raising device 8, and when it is inserted into the rice bowl storage pit 9, the triangular pieces 42, 42 at both corners of the upright piece 41 are bent into two directions as shown in FIG. It is bent along the side and protrudes from the bottom of the rice ball 11. In this state, the packaging sheet folding plate 12 reciprocates to fold one of the protruding triangular pieces 42 onto the bottom surface (this state is shown in FIG. 16). Then, when the sliding plate 10 rotates 90 degrees around the support shaft 14, the next empty pit 9 rotates to that position, and the rice ball 11
rotates in the direction of arrow b in Fig. 7, contacts the fixed folding plate 13, and the other protruding triangular piece 42 is also folded onto the bottom surface as shown in Fig. 17, further rotates 90 degrees and stops. Then, the labeler 37 operates to attach the bottom folded triangular pieces 42, 42 to the label 43 as shown in FIG.
When the packaged rice ball 11' is further rotated 90 degrees and stopped, the packaged rice ball 11' is pushed onto the unloading chute 38, and the unloading operation is repeated.

"Embodiment" The upright intermittent sliding plate 10 may be a disc that rotates intermittently around the support shaft 14 as shown in FIG.
A plurality of the pits 9 are formed at equal intervals. In the rice-handling stand-up device 8, a push plate 16 moves the arc arm 1 from a horizontal position to an upright position inside an arc-shaped guide tube 15 with an opening angle of 90 degrees.
7, and the cross section of the guide cylinder 15 is approximately 3
formed into a square shape. The arc arm 17 is connected to the support shaft 18 with spokes 19, and the arm 17 is connected with the cylinder 20.
Can be raised and lowered 90 degrees. The lateral extrusion device 7 is reciprocated by a cylinder 21, and its tip is formed into a V shape and comes into contact with two sides of the triangular rice grip 11 (see FIG. 6). The rice ball flat packaging sheet folding tools 6, 6 move in and out of the guide plates 3, 3 through the cylinder 22, and the triangular pieces 2 of the packaging sheet 23 standing upright from the two sides of the rice ball 11.
4 and 24 (Figures 12 and 13). A rice-gripping plane (upper surface) lowering cylinder 25 is provided above the rice-gripping supply port 2 along the center line of the triangular tube 4, and a rice-gripping bottom surface is provided below the through-hole 26 of the traverse guide plate 5 along the same center line. (Bottom surface) A descending guide cylinder 27 is provided. In addition, what is shown by 29 in FIGS. 1 to 3 is a rice grip supply table that slides back and forth on the above-mentioned supply table 28;
30 is a nearly triangular supply hole drilled in the same base 29;
31 in FIG. 4 is a light source that illuminates the through hole 30 from below;
2 is a flange for fixing the packaging sheet, 33 is a seaweed sheet housed in the same sheet 23, 34 in FIG. 5 is a front receiving plate for rice balls provided in the pit 9, 35 is a spring for extruding rice balls, 36 in FIG. 9 1 is a rice ball extrusion cylinder, 37 in FIG. 1 is a labeler for folding the rice ball bottom folding packaging sheet, 38 is a chute for taking out the packaged rice ball, 39 is a cylinder for reciprocating sliding of the movable folding plate 12,
40 in Fig. 5 is the support spring for the cross-feeding guide plate 5.
can be raised and lowered slightly.

"Effects of the Invention" Since the present invention is configured as described above, the packaging sheet 23 is supplied onto the supply table 28, and the triangular rice ball 11 is placed on the supply port 2 of the table 28 via the sheet 23.
This has the advantage of being able to supply and easily package the same with the packaging sheet 23, thereby enabling mass production of packaged rice balls.
