Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a packaging device for short cylindrical seaweed-wrapped rice balls.

``Prior Art'' Previously, a device was devised to automatically cover both ends of a short cylindrical rice ball before wrapping it in a rectangular plastic thin-film flat bag holding seaweed, but it has not been possible to ensure a smooth and reliable covering operation. Lacking sex (patent application 1986-200810)
issue).

``Problems to be solved by the invention'' The purpose of this invention is to obtain a packaging device that can smoothly and reliably cover both ends of a short cylindrical rice ball before rolling it into a rectangular plastic thin film flat bag holding seaweed. It is something.

``Means for solving the problem'' This proposal stores rectangular dried seaweed in a rectangular plastic thin film flat bag, and uses a packaging sheet with covering pieces protruding from both longitudinal edges of the flat bag. In a packaging method in which both ends of a short cylindrical rice ball placed on a flat bag are covered with the above-mentioned both-side covering pieces, and in that state the rice ball is rolled into the flat bag and covered in a cylindrical shape, an intermittent rotating circular shape is attached to the machine frame. A stand is provided, openings for lowering the rice grip are bored at equal intervals along the outer circumference of the stand, and upright support plates of the both-side covering pieces are connected to the outside of both ends of the opening. The nori-wrapped rice grip packaging device is arranged with a space between the supporting plates and supports the supporting plate so as to be able to be folded down above the opening, and is provided with a device that links the folding down with the rotation of the circular table. be done.

``Operation'' Therefore, the intermittent rotating circular table 2 repeats the intermittent operation in which it rotates and stops at intervals of the openings 4, and in the stopped state, the rectangular plastic thin film flat bag 5' is placed on the openings 4. When placed, both side covering pieces 5,
Reference numeral 5 denotes the above-mentioned upright support plates 6, 6 on the outside of both ends of the opening 4.
In this state, the short cylindrical rice ball 3 is placed on the flat bag 5' on the opening 4.
When the opening 4 rotates by the above-mentioned distance on the lower winding device (not shown) and stops, the rotation causes the interlocking device 7 to operate and move the upright support plates 6, 6 together. Lay it down on top of rice ball 3. Therefore, the covering pieces 5, 5 on both sides, which were supported upright by the supporting plates 6, 6, lie down on the upper surfaces of both ends of the rice ball 3, and cover both end surfaces and the upper surface of both ends. In this state, it is supplied from the opening 4 to the winding device below.

``Example'' A circular table 2 that rotates intermittently every 60 degrees is provided on the outer periphery of a central fixed cylinder 8 on a machine frame 1. Six rectangular openings 4 are bored along the outer periphery of the circular table 2 at intervals of 60 degrees. On the outside of both ends of this opening 4 are low steps 4',
4', and the upright supporting plates 6, 6 of the covering pieces 5, 5 on both sides of the rice ball 3 are arranged on the upper part of the low stage 4', 4' with a gap between them and both ends of the opening 4. . The support plates 6, 6 are supported on the reciprocating rotation shaft 9 so that they can be laid down horizontally above the opening 4. An upright weight 10 is provided at one end of the rotating shaft 9, and a horizontal arm 11 for operation is protruded from the upper end of the weight 10.
As it rotates in the direction of arrow a, the upright weight 10 and the upright support plate 6 are brought down horizontally by hitting the stopper 12 provided on the fixed cylinder 8, and the reciprocating rotation axis 9 of the other upright support plate 6 is lowered horizontally. An upright weight 10 is also provided at the tip,
An operating upright arm 11' is provided at the upper end of the weight 10,
The pin 13 protruding from the circular base 2 rotates the short transverse arm 15 protruding from the lower end of the upright floating shaft 14 provided on the fixed cylinder 8 in the direction of arrow a. The long horizontal arm 16 provided on the upper part of the shaft 14 is rotated in the direction of arrow b, and the above-mentioned upright arm 1 is rotated by the rotation.
1', the upright weight 10 and the other upright support plate 6 can be laid down horizontally. The interlocking device 7 is formed by arranging the stopper 12, the short lateral arm 15, and the long lateral arm 16 so that the left and right support plates 6, 6 are simultaneously collapsed from the solid line position to the imaginary line position in FIG. In the drawing, 17 indicates a weight for maintaining the support plate 6 in the upright position, and 18 indicates a suction cup that moves up and down the opening 4 to erect the support plates 6, 6 which are in a collapsed state. ' can be suctioned and supplied onto the opening 4. 5'' is the rectangular dried seaweed in the flat bag 5', 19 is an adhesive tape, 20 is a pasting device for the adhesive tape 19, 21 is an air suction port, and 22 in FIG. The lowering plate pushed into the opening 4, 23 in FIG. 2 is a traction spring for the long horizontal arm 16.

``Effect'' Since the present invention is constructed as described above, simply by supplying the rectangular plastic thin film flat bag 5' onto the opening 4, the covering pieces 5, 5 provided on both sides of the bag will stand up, and there will be a short section in the middle. By simply supplying the cylindrical rice ball 3 and rotating the circular table 2 at a predetermined interval, both ends of the rice ball 3 can be automatically covered with the covering pieces 5 , 5 smoothly, reliably, and easily for the next rolling. It can be sent to the process.
