For example, each component can be individually driven by a cylinder or the like, and the entire operation timing is sequentially controlled by a control device such as a sequencer. You may comprise so that it may do.

  The operation of the present invention will be described below. It is assumed that the seaweed storage film F with the seal S adhered to the tip is placed on the conveyor 1 as shown in FIG. 1 and is carried to the position X2.

  The drive motor M2 is driven to intermittently drive the intermittent rotation disk 3. Then, the intermittent rotation disk 3 rotates intermittently in the direction of arrow B by 45 degrees. The operator stores the cylindrical rice R in the rice storage hole 4 at the position X3 when the disk 3 is stopped. In addition, a tool is inserted in the cylinder of the cylindrical rice R in advance. When the sensor 80 detects that the cylindrical rice R is stored in the rice storage hole 4, the drive motor M1 is intermittently driven, the conveyor 1 is driven by a certain distance, and the laver storage film F reaches the packaging position X1. It is transferred and stops once. When the sensor 80 does not detect the presence of the cylindrical rice R, the conveyor 1 is not driven. Moreover, since the rice receiving members 6a and 6b are closed at the bottom of the rice storage hole 4 of the intermittent rotating disk 3, the cylindrical rice R is placed on the rice receiving members 6a and 6b. Yes. For this reason, the bottom part of the cylindrical rice R does not contact the upper surface of the fixed disk (lower surface) 5, and the rice grains at the bottom part of the cylindrical rice R are not cut or crushed by the rotation of the intermittent rotation disk 3.

  After the film F is transferred to the packaging position X1, the slide blocks 9a and 9b are opened in the directions of arrows C and C ′ by the forward movement of the operating rod 67, thereby opening the rice receiving members 6a and 6b (see FIG. 2 to FIG. 3), the cylindrical rice R in the rice storage hole 4 is placed on the rice push-up block 11 (state of FIG. 3).

  Next, the rice push-up block 11 is raised by the raising operation of the operating rods 65 and 66. The rice push-up block 11 passes through the rice storage hole 4 while lifting the cylindrical rice R and reaches between the belts 1a and 1b of the conveyor 1, and at this time, the upper portion of the cylindrical rice R is the belt 1a. , 1b abuts on the rear portion F4 of the laver storage film F from the lower side (state shown in FIG. 4).

  When the rice push-up block 11 further rises, the cylindrical rice R rises in the laver folding passage 17, but before entering the passage 17, the pressing plate 17 d contacts the upper surface side of the laver storage film F. The contact between the laver storage film F and the cylindrical rice R is ensured by the weight of the presser plate 17d.

  The rice push-up block 11 ascends the laver folding passage 17, and in the ascending process, the rear edge of the rear portion F4 of the laver storage film F is bent downward by contacting the rear folding block 17b, Further, the upper surface of the belt-shaped peripheral surface covering portion F3 is bent downward by coming into contact with the front bent block 17a, and the left and right side surface extension portions F2, F2 of the laver storage film F are formed on the side bent plates 17c, 17c ′. By abutting, it is bent downward along the side surface of the cylindrical rice R, whereby the laver storage film F is bent so as to cover the front, rear, left and right of the cylindrical rice R (FIG. 20B). At this time, the side surface extensions F2 and F2 of the film F are reliably bent downward by coming into contact with the pressing plates 18 and 18 ′ at the lower ends of the side surface bent plates 17c and 17c ′ (FIGS. 5 and 7). reference).

  The rice push-up block 11 passes through the laver folding passage 17 and further rises, and rises to a position where the upper part of the folded laver storage film F comes into contact with the winding belt 40 to stop the raising operation (FIG. 6). State). At this time, as shown in FIG. 20B, the laver storing film F is bent downward on the front and rear sides and the left and right side surfaces of the cylindrical rice R.

Next, since the operating rod 65 starts to descend, only the side block 11b of the rice push-up block 11 starts to descend (see FIG. 8). At this time, the cylindrical rice R is still placed on the central block 11 a of the rice push-up block 11.
When the side block 11b is lowered, the central shaft 24b is rotationally driven in the direction of the arrow H ′ by the backward movement of the operating rod 68 (FIG. 19A), whereby the rotating arms 23a and 23b are moved in the proximity direction (arrow). H, H ′), and the rice press rollers 14a, 14b move to positions where they contact the side surface extensions F2, F2 of the film F of the cylindrical rice R (see the directions of arrows E, E ′, FIG. 8). ).

  Next, due to the backward movement of the operating rod 69, the central shaft 30a is rotationally driven in the direction of arrow H (FIG. 19B), whereby the rotating arms 29a and 29b are moved in the proximity direction (arrows H and H ′). The folding pieces 15a, 15b are driven in the proximity direction (arrow E, E ′ direction). Thereby, the said folding pieces 15a and 15b enter into the lower surface side from the left-right side surface direction of the said cylindrical rice R. FIG. Then, the folding protrusions 15 ′ and 15 ′ at the tips of the folding pieces 15a and 15b enter the lower side of the cylindrical rice R while abutting against the side surface extensions F2 and F2 of the laver storage film F (FIG. 9). By this operation, the side surface extensions F2 and F2 are folded into the lower side of the cylindrical rice R (FIG. 20C).

  When the folding pieces 15a and 15b are driven close to each other and the side surface extensions F2 and F2 are folded inward, immediately after that, the operating rod 66 descends and the central block 11a of the rice push-up block 11 descends. Therefore, the cylindrical rice R which has been placed on the central block 11a until then is placed on the plate surfaces of the folding pieces 15a and 15b (the state shown in FIGS. 8 to 9). At this time, the side surface extensions F2 and F2 of the seaweed storage film F are folded downward from the left and right sides of the cylindrical rice R (state shown in FIG. 20C).

  The central block 11a is lowered to the lowermost end together with the side block 11b, and then the operating rod 67 is moved rearward, whereby the rice receiving members 6a and 6b of the intermittent rotation disk 3 are closed.

  Next, when the folding operation of the left and right side surface extensions F2 and F2 is completed, the central shaft 30a is rotationally driven in the direction of arrow I by the forward movement of the operating rod 69 (see FIG. 19B). As a result, the folding pieces 15a and 15b are driven in directions away from each other (in the directions of arrows G and G ′), and the folding pieces 15a and 15b return to the initial positions (positions in FIG. 8).

  At substantially the same time as this operation, the vertical shaft 75 is rotationally driven by the backward movement of the operating rod 70 (FIG. 11), whereby the receiving plate 16 slides forward from the rear of the cylindrical rice R, and the receiving plate 16 It moves to the lower surface side of the cylindrical rice R, and the said cylindrical rice R will be in the state mounted on this receiving plate 16 (state of FIG. 11). At this time, the rear portion F4 of the laver storage film F on the rear side of the cylindrical rice R is folded forward and forward on the lower surface side of the cylindrical rice R by the front edge of the receiving plate 16, and the rear portion F is the cylindrical rice R. It will be in the state folded into back from the back side (state of FIG.20 (c)).

  Thereafter, the drive rod 44 is raised by the upward movement of the operating rod 72, whereby the gears 41 and 41 'are rotationally driven, whereby the belt opening and closing arms 33 and 33' are closed via the belt opening and closing drive shafts 32 and 32 '. Driven in the direction (arrow L, L ′ direction), as shown in FIG. 13, the connecting rollers 34, 34 ′ move to a position where they contact the front and rear circumferential surfaces of the cylindrical rice R, The entire cylindrical rice R is covered together with the laver wrapping film F (state shown in FIGS. 11 to 13).

  In such a state, the connecting rollers 34 and 34 ′ are in parallel with the front and rear circumferential surfaces of the cylindrical rice R, and a part of the winding belt 40 is in close contact with the circumferential surface of the cylindrical rice R. Contact. The winding belt 40 is wider than the horizontal widths of the cylindrical rice R and the laver storage film F and has a horizontal width that covers the front half of the left and right rice press rollers 14a and 14b (see FIG. 9). ) In such a covering state, the cylindrical rice R and the laver storage film F and the front half of the left and right pressing rollers 14a and 14b are covered. Accordingly, the seaweed storage film F is in close contact with the substantially entire peripheral surface, leaving a part of the lower surface of the cylindrical rice R, and the belt-shaped peripheral surface covering portion F3 of the seaweed storage film F is suspended from the rollers 34 and 34 '. It will be in the state (state of FIG. 13).

  Thereafter, the drive motor M3 is driven for a certain period of time, whereby the winding belt 40 is rotationally driven in the direction of arrow J. Then, the cylindrical rice R covered with the winding belt 40 rotates in the direction of the arrow K, whereby the belt-shaped peripheral surface covering portion F3 is wound by the winding belt 40, and the covering portion F3 is rotated around the cylindrical rice R. The entire surface is covered. At this time, the seal S at the end of the belt-shaped peripheral surface covering portion F3 is adhered to the film F surface, and peeling of the end of the belt-shaped peripheral surface covering portion F3 is prevented (state shown in FIG. 20 (d)).

  When the driving of the driving motor M3 for the predetermined time is completed, the operating rod 72 is lowered, so that the belt opening / closing arms 33, 33 ′ are closed from the closed state via the belt opening / closing driving shafts 32, 32 ′ to FIG. Driven to the open state shown. Accordingly, the cylindrical rice R covered with the seaweed storage film F (hereinafter, the cylindrical rice R in the packaged state is referred to as “wrapping rolled sushi R ′”) is placed on the receiving plate 16. .

  Thereafter, when the operating rod 70 moves forward, the operating rod 73 moves in the front-rear direction substantially simultaneously. Then, due to the movement of the operating rod 70, the receiving plate 16 moves rearward and the unloading arm 48 rotates in the direction of the arrow T, so that the contact plate 48a contacts the packaged sushi roll R ′. After the rolled sushi R ′ is moved rearward and the wrapped sushi R ′ is dropped downward from the discharge port 20d, the arm 48 is rotated in the direction of the arrow T ′ to return to the initial position (FIG. 15). reference).

The wrapping sushi roll R ′ dropped from the outlet 20d falls on the conveyor 50 below the outlet 20d, and is conveyed in the direction of arrow U by the conveyor 50 and unloaded.
The intermittent rotating disk 3 rotates intermittently so that the cylindrical rice R stored in the next rice storage hole 4 is positioned at the packaging position X1 and the next laver storage film F is wrapped by the intermittent drive of the conveyor 1. Located at position X1.

  Thereafter, the series of operations are repeated by the subsequent rotational drive of the drive motor M4, and the wrapped sushi roll R 'is sequentially formed.

  Moreover, the whole packaging apparatus can be comprised compactly by using the intermittent rotation disk 3 as a conveyance means of a cylindrical food.

  Moreover, a packaging film can be folded with respect to a cylindrical food only by making a cylindrical food pass up in the laver folding channel | path 17, and the structure which concerns on folding of a packaging film can be comprised simply.

  In addition, since the cylindrical food such as the cylindrical rice R is supported by the rice pressing rollers 14a and 14b on the left and right sides and the presser roller is rotated by the winding belt 40, stable rotation can be realized and packaging can be performed appropriately. Films can be rolled in and the cylindrical food can be packaged neatly.

  In addition, since the lower surface of the cylindrical food is placed on the rice receiving member that is closed while being transported by the intermittent rotary disk 3, the lower part of the cylindrical food may be brought into sliding contact with the fixed plate by the rotation of the disk. In addition, the cylindrical food can be conveyed in a clean state.
