DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically packing seaweed rolled rice.

[0002]

2. Description of the Related Art In order to automate the production of so-called "straw-rolled rice balls" in which rice balls are directly rolled with laver in a bag, the rice balls are rolled with laver. Positioning → Opening the bag → Put the rice balls deep into the bag so that the seaweed does not become damp and difficult to enter the bag → Fold the bag for no looseness → Apply a label etc. Since it is difficult to automate bagging such as high-speed feeding and accurate positioning, production is currently performed with a large number of people.

BEST MODE FOR CARRYING OUT THE INVENTION A center c "of a rice-shed accommodation through-hole 3 formed at equal intervals on the outer periphery of a first disk 1 and a rice-shed storage notch 4 formed at equal intervals on the outer periphery of a second disk 1 '. When the center line d was intermittently stopped on a straight line L connecting the centers c and c 'of the disks 1, 1', the packaging bag was placed on the horizontal supply intermittent conveyor 5 at the interval w between the disks 1, 1 '. The synthetic resin transparent packaging bag 6 is stopped, and the opening 7 of the packaging bag 6 is straightened L toward the through hole 3.
The center c ″ and the center line d of the through hole 3 are stopped on the straight line L.
To match. Instead of the intermittent conveyor 5, a continuous conveyor may be used and the packaging bag 6 may be stopped by the stopper 5 '.

In this operation, positioning is performed by stopping the intermittent pulley motor 13 of the conveyor 5 (see FIG. 2), and the stopping of the motor 13 is performed by the first and second disks 1, 1 '.
The operation can be performed by a limit switch linked to the rotation of the switch, the operation of the switch, a stop operation cam, and the like (not shown).

When the lowermost bag 6 'is sandwiched and lowered by the air suction opening and closing suction cups 18, 18 which are opened and closed by the rotation of the pinions 20 ", 20" meshing on both sides of the lowermost bag, the lowermost bag 6' becomes two belts 15, 15 And the first and second disks 1, 1 'interlock with the operation of the conveyor 5 intermittently moving and stopping the center line of the lowermost bag 6' at the position of the center line d. You can do it.

As shown in FIG. 2, the center c ″ of the through hole 3 is
It stops in the state where the center line of the lowermost bag 6 'and the center line d of the notch 4 coincide with the straight line L. In this state, the lower layer 7 'of the opening of the packaging bag 6 (the lowermost layer bag 6') protrudes leftward in FIG. 2 from the upper layer 7 ", and the protruding portion is stopped by being pressed from above by the lifting presser foot 21. In this state, the nozzle 8
Air is blown into the opening 7 from above, and the upper layer 7 ″ is lifted by the suction cup device 22 for opening, so that the opening 7 is opened as shown in FIG.
Open.

In this state, as shown in FIG. 5, the seaweed-coated rice cake 10 pushed up from the through hole 3 of the first disk 1 onto the disk 1 by the cylinder 23 is put into the opening packaging bag 6 by the pushing tool 11. It is transferred to the stopper 24 above the notch 4 of the second disk 1 '. In this state, when the elevating stamp 12 provided on the elevating machine frame 25 is lowered with the lowering of the machine frame 25, the packaged rice-grinding rice 10 is pushed into the notch 4 by the stamp 12. At this time, while being pressed by the stamp 12, the receiver 30 ′ shown in FIG. 7A is lowered into the through hole 2 ″ formed in the fixed base plate 2 ′, and is pressed into the notch 4 neatly.

The elevating guide shaft 12 'of the stamp 12 is slidably supported in an upright guide tube 26 provided in an elevating machine frame 25, and the stamp 12 is urged downward by the small-diameter coil spring 12 "or its own weight. At the lower end of the upright guide tube 26, the top of a bent horizontal rod having an operating arm 27 and an operating arm 28 orthogonal to one body is pivotally supported by a horizontal axis 29, and the operating arm 27 is descended by a large diameter spline 26 '. The working arm 28 is provided with a pressing plate 28 ′ that presses the upper layer 7 ″ of the opening portion of the rice-shrink wrapping bag 6 against the outer surface of the rice-shoulder 10.

The bent horizontal rod descends with the elevator frame 25,
The tip of the operating arm 27 is in contact with the upper surface of the transfer stop stopper 24, and the bent horizontal rod is lowered against the ridge 26 'and rotated about the horizontal axis 29, and the pressing plate 28' is moved to the upper layer 7 of the opening. A reciprocating sliding fastener 30 is provided which closes the lower portion of the package 7 and contacts the upper layer 7 "to the rice-grinding side, and presses the upper opening lower layer 7 'of the packaging bag 6 to the outside of the upper layer 7" in this state. Notch 4
Are provided in the openings.

Thereafter, the first and second disks 1 and 1 'are simultaneously rotated to the next position of the through hole 3 and the position of the notch 4 to stop, and the conveyor 5 is rotated to stop the next packaging bag. 6 is repeated on the straight line L.
