Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for forming rice into a rod shape while simultaneously packaging the rice.

[0002]

2. Description of the Related Art Conventionally, an apparatus for automatically forming rice into a rod shape and an apparatus for automatically packaging rice in a rod shape have been put into practical use. However, the automatic forming of the stick-shaped rice and the packaging of the stick-shaped rice are performed separately, and it is necessary to form the stick-shaped rice into a stick shape and package the stick-shaped rice once. There was a problem that the bar-shaped rice lost its shape during the packaging process, impairing the commercial value. The present invention clarifies an apparatus that can efficiently produce a packaged stick-shaped rice without breaking the shape by supplying the rice on a packaging sheet in a mold and forming the rice into a rod-like shape.

[0003]

According to the present invention, a rice feeding device (1) for feeding a fixed amount of rice R stored in a hopper (11) and a lower part of the downstream end of the rice feeding device (1) on a base. A mold (2) that is slidably arranged on the upper and lower sides and the lower opening is closed by a base (9), and a mold (2) above the mold (2) at the standby position. A packaging sheet feeding device (3) that approaches each other and feeds the packaging sheets (100) one by one, and is arranged so as to be able to move up and down above the formwork at the standby position and from inside the formwork (2) from above the packaging sheet (100). The pressing plate (41) for pressing the rice R supplied to the mold and both ends (101a) (101b) of the packaging sheet (100) that is placed near the mold (2) and protrudes from the mold (2). A folding device (7) for folding inwardly so that they overlap each other, and a joining device for joining the overlapping part of the packaging sheet, which is provided above the first advance position of the form (2).
(5) and a punching-out device (6) which is arranged so as to be able to move up and down above the second forward position in the mold (2) and which pushes the packing stick-shaped rice W of the mold (2) from the lower surface opening of the mold (2). ) And.

[0004]

[Operation and effect] The packaging sheet feeding device (3) feeds the packaging sheet (100) above the formwork (2) at the standby position.
(Figure 2) (Figure 9). The packaging sheet (10
A fixed amount of rice R is supplied into the mold (2) from above (0) (FIG. 3). The presser plate (41) descends to press the rice R in the mold (2) to form the rice into a rod shape corresponding to the mold (2) (FIG. 4). The both ends of the packaging sheet (100) protruding from the mold (2) are folded inward by the folding device (7) so that they overlap each other (Fig. 6). The mold (2) advances to the first advance position. After stopping, the joining device (5) joins the overlapping portions of the ends of the packaging sheet (100) (FIG. 7). When the formwork (2) further advances to reach the second advance position, the wrapping bar-shaped rice W is pushed down from the lower surface opening of the formwork (2) by the piercing device (6). By repeating the above steps, the packaged stick-shaped rice can be efficiently produced.

As shown in FIG. 4, the wrapping sheet (10
Since the central portion of 0) and the rice R are accommodated and the rice is pressed in the mold (2) for molding and packaging, the stick-shaped rice W is not likely to lose its shape. From the feeding of rice R into the formwork (2), the packing rod-shaped rice W
It is hygienic and does not come into contact with human hands until it is discharged.

Move to the form (2) side at the standby position by 4), and
Position (100) on the form (2) (Fig. 2). Rice feeding device
The belt conveyor (14) of (1) is stopped at the timing when the rice R leveled by the leveling roller (12) reaches the downstream end of the belt conveyor (14). At the same time, the scraping plate (15) descends and further advances to scrape the rice R on the belt conveyor (14) downward from the downstream end of the belt conveyor (14).

The rice R scraped off from the belt conveyer (14) passes through the elevating frame (24) and the packaging sheet (1) on the form (2).
00) and drop the center of the packaging sheet (100) into the formwork (2).
(Fig. 3). As shown in FIG. 11, both ends of the rectangular bag body (101) of the packaging sheet (100) and both ends of the band film (102) are slightly tilted outward from the upper opening edge of the formwork (2) to protrude.
The elevating frame (24) descends, and lightly presses the base end of the protruding portion of the packaging sheet (100).

The pressing plate (41) of the rice pressing device (4) descends,
The rice R is pressed into the mold (2), and the rice R is formed into a rod shape corresponding to the mold (2) (FIG. 4). Simultaneously with the formation of the bar-shaped rice, both ends of the bar-shaped rice are wrapped with the band film (102) of the packaging sheet (100), and the lower surface and the front and back surfaces of the bar-shaped rice are rectangular bags (10).
2) Wrapped by. When the rice R is pressed while the protruding portion of the packaging sheet (100) from the formwork (2) is lightly pressed by the elevating frame (24), the rice can be spread to every corner of the formwork (2). At the same time, in order to stretch the packaging sheet (100) inside the formwork (2),
The wrapping sheet (100) can be prevented from wrinkling, and the sheet can be wound around the stick-shaped rice in a tensioned state.

The holding plate (41) rises, the hopper (81) of the sprinkling device (8) moves to the rice feeding device (1) side, and the shutter lid (84) of the sprinkling device (8) momentarily opens. , Hopper (8
The sprinkled food in 1) is sprinkled on the stick-shaped rice in the formwork (2).

The elevating frame (24) rises, and the folding device (7) operates at this timing. First, the left and right claw plates (71) (71) of the folding device (7) approach each other by scratching the ends (102a) (102a) of the strip film (102) of the packaging sheet (100), Fold the film ends (102a) (102a) on the stick-shaped rice. Next, the rear claw plate (72) is the rear end of the rectangular bag body (101).
(101a) is moved forward by scratching, and the rear end portion (101a) is covered on the stick-shaped rice from above the folded film end portions (102a) (102a). Next, the front nail plate (73) is the front end portion (101b) of the rectangular bag body (101).
After scratching, move to the rear claw plate (72) side, and the front end (101b)
The rectangular bag (101) on the folded back end (101a)
(Figure 6). In this state, the entire outer peripheral surface of the bar-shaped rice in the mold (2) is wrapped with the packaging sheet (100).

The mold (2) advances and stops at the first advance position. The front claw plate (73) is covered above the transition path of the mold (2), and since the claw plate (73) extends to the vicinity of the first forward movement position, the packaging sheet (100) is wound. It is possible to prevent the rear end portion (101a) from standing up. The elevating plate (51) of the joining device (5) descends at the timing when the mold (2) stops at the second forward position, and the heating pieces (53) (53) on the lower surface are moved to the rear end portion of the film ( 101
Press on a) and heat weld to join.

The elevating plate (51) rises and the mold (2) moves to the second forward position. The punching plate (61) of the punching device (6) descends at the timing when the formwork (2) stops, and the packing rod-shaped rice W is discharged from the opening (92) of the base (9) to the discharge conveyor ( 9
3) Drop it up. By repeating the above steps, the packaged stick-shaped rice W can be efficiently produced.

In practicing the present invention, the sprinkling device (8) may be omitted. Also, the packaging sheet (100) is a strip film (10
2) can be omitted. The joining device (5) is not limited to the above-mentioned heat welding, but may be a device that automatically attaches a seal piece to the end of the sheet. The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the claims.
