A folding device (75) that folds the exposed sheet ear pieces S4 so as to overlap with the rice ball, a heat welding device (77) that heat-welds the folded sheet ear pieces S4, and the downstream side of the first table (1). A discharging device (8) for opening and closing a closing plate (81) that closes the triangular hole (12) of the sheet and opening the closing plate (81) after the sheets are heat-sealed to discharge the rice ball W. Or Ranaru.

3 to 7 show an operation sequence of the apparatus, and FIG. 8 shows a packaging procedure corresponding to the operation of the apparatus. Place the rice ball W on the push-up plate (31) that closes the triangular hole (11) on the upstream side of the first table (1) (Fig. 3).

The lowermost packaging sheet S of the bundle of packaging sheets stacked on the stocker (44) is adsorbed by the moving frame (41) of the sheet conveying device (4) and conveyed above the rice ball W. When the rice ball W is pushed up, the packaging sheet S waits in a state of being shifted forward so as to hit the rear portion of the packaging sheet S (Fig. 4).

The rice ball W is pushed up by the push-up device (3) and passed through the triangular hole (21) of the second table (2) together with the packaging sheet S, and the rice ball feeder (5) waiting is fed. Fit into the triangular hole (52) of the frame (51) (Fig. 5). At this time, the sheet is folded downward along the three sides of the rice ball W by the edge of the hole (FIG. 8b). The upper surface and the three sides of the rice ball are wrapped together by the sheet folding pieces S1 and S2.

The rice ball is horizontally moved by the rice ball feeder (5) toward the triangular hole (22) on the downstream side of the second table (2) as shown by an arrow P (FIG. 6). A guide plate (53) is provided above the moving path of the rice ball. When the rice ball W advances, the folded piece S2 hanging from the bottom is hooked on the hole edge of the triangular hole (21) and folded back to the lower surface side of the triangular rice ball (Fig. 8c).

The rice ball W is forcedly pushed down from the triangular hole (22) by the thrusting device (6) and is placed on the closing plate (81) that closes the triangular hole (12) on the downstream side of the first table (1). (Fig. 7). At this time, the quadrangular piece S2 is folded upward along the two sides of the rice ball (4) by the edge of the triangular hole (22) (FIGS. 8c and 8d).

The folding device (75) for the seat ear piece S4 is composed of a pair of arms (76) and (76) that rotate in a horizontal plane. The arms (76) and (76) rotate with a time shift, The tabs S4 and S4 of the sheet protruding above the upper surface of the rice ball (4) are folded on top of the rice ball, and the heating piece (78) of the heat welding device (77) is lowered while keeping this state. Then, the overlapping portion of the sheet ear piece S4 is heat-welded (FIG. 8e). The rice balls are packaged by the above process. The closing plate (81) is opened by the cylinder (82) and the packaging rice ball is discharged.

[0009]

[Problems to be solved by the device]

 In the above packaging device, the device (75) for stacking and folding the rising ear piece S4 of the sheet on the rice ball W and the device (77) for heat-welding the overlapping portion of the sheet ear piece S4 are separate. The heating piece (78) must be lowered while the sheet selvage piece S4 is held on the rice ball W by the folding device (75). Since the ascending / descending path of the heating piece (78) is also the ascending / descending path of the falling plate (61) of the protruding device (6), it is possible to move the falling plate (61) up and down on the falling plate (61). However, there is a problem that the mechanism is complicated because the heating piece (78) must be installed so that it can be moved up and down independently, or the heating piece (78) must be pushed down and retracted from the transition path of the plate (61). It was The present invention discloses a rice ball wrapping device that can simplify the mechanism by making the sheet ear piece folding device (7) also serve as a heat welding device.

[0010]

[Means for solving the problem]

 In the conventional sheet wrapping device, the sheet ear piece folding device (7) includes a pair of push plates (71) (71) which move forward so as to incline the rising ear piece S4 of the packaging sheet S from the outside to the inside. A heating piece (70) is provided on the lower surface, and a cam (73) is connected to the pressing plate (71) so that the pressing plate (71) descends near the forward end.

[0011]

[Operation and Effect] When the pair of push plates (71) (71) move forward with a time shift, the sheet ear piece S4 rising from the side edge of the rice ball W is folded and pushed so as to overlap with the upper surface of the rice ball W. The plate (71) descends at the forward end, and the heating piece (70) on the lower surface strongly presses the sheet ear piece S4 to heat-weld the sheet ear piece S4. As described above, the heating piece (70) for heat welding is provided on the lower surface of the pressing plate (71) for folding the sheet ear piece S4, and the sheet ear piece folding device (7) also serves as the heat welding device. The mechanism is simplified.
