The present invention relates to a packaged food such as rice balls, a packaging method thereof, a packaging device, and a packaging sheet.

In the packaging form of the "rice ball" sold at a convenience store, as shown in FIG. 38, the rice ball 401 was wrapped in the shape by the packaging sheet 200 (refer to Japanese Patent Laid-Open No. 2003-192075). And the rice ball 401 are accommodated in the packaging bag 300 as shown in FIG.

As for the former packaging form, as shown in FIGS. 40-42, the sheet | seat-shaped seaweed 206 is sandwiched between the outer film 201 and the inner film 205, and the packaging sheet 200 is formed, and this The packing sheet 200 is used to block the sheet-shaped seaweed 206 from the rice balls 401 and the outside air. Accordingly, the laver 206 is kept in a dry state so as not to impair the flavor or texture of the laver. In addition, the rice balls can be simply unpacked by applying a cut tape 203 to the outer film 201 to form the dividable portion 202. When the cut tape 203 is pulled up and unpacked, the sheet-shaped seaweed 206 is naturally covered with the rice balls, which is convenient to eat.

The packaging sheet 200 sandwiches a rectangular sheet-shaped laver 206 between the transparent outer film 201 and the translucent inner film 205, and forms an outer circumference of the outer film 201 and the inner film 205. It is formed by welding 208.

The sheet-like seaweed 206 is smaller than the outer film 201 and is about the size of being covered by the onigiri 401. The inner film 205 is formed by stacking two narrow rectangular pieces of film pieces 205a and 205a in a width overlapping with inner edges of 5 mm to 10 mm along the lengthwise direction.

The margin which both edges pushed out from the rice ball 401 along the longitudinal direction of the packaging sheet 200 is called an edge part.

In the packaging form shown in FIG. 38, the rice ball can be packed with high efficiency by the automatic packaging device, and the packaging cost can be reduced.

The packaging form of FIG. 39 has arisen from the recent high-end orientation, and has the effect of showing a rice ball large compared with the former which the shape of a rice ball appears as a packaging form as it is.

However, the packaging bag 300 is formed of one sheet, and the seaweed directly touches the onigiri. For this reason, the seaweed becomes damp until it is eaten, and the reputation is bad for a prisoner who wants to taste the dry seaweed flavor and texture.

In addition, in the packaging form of FIG. 39, since rice balls are manually put into the packaging bag 300, the efficiency of filling the bags does not increase, resulting in a problem of high cost.

In addition, in the packaging form of FIG. 39, when unpacking, the bag-shaped cutout 306 applied to the opening sealing part 303 of the bag is sandwiched, and the sealing part 303 of the bag is held by the thumbs f1 and f2. ) And tear off the packaging bag from the notch 306. Since the rice ball is not pressed by hand, the rice ball 401 falls from the bag when the packaging bag 300 is torn into two pieces. As a result, the onigiri 401 is crushed to the extent that it cannot maintain its original shape, and it becomes impossible to eat.

Operation from rice ball molding to discharge

Next, the operation | movement until the rice ball is shape | molded by the rice, and the rice ball is packaged by the packaging sheet 200, and discharged are demonstrated.

Operation of rice ball forming device

As shown in FIG. 1, the rice of the amount of 1/2 of the triangle rice ball to be shape | molded is supplied to the die | hole hole 21 of the 1st turntable 2 by the 1st rice supply part 11. The first pressing member 15 is lowered to the mold hole 21 stopped at the preforming station S2, and the rice is molded into a rice lump having a thickness of 1/2 of a triangle rice ball (see FIGS. 3 and 4). ).

When the die hole 21 stops at the speed | rate injection station S3, the inside of a rice lump is thrown in by hand or an automatic speed feeder (not shown).

During the above operation, the second rice supply part 12 is also supplied with the amount of 1/2 of the amount of triangle rice balls to be molded into the mold hole 31 of the second turntable 3. In the preforming station S5, the third pressing member 35 is lowered, and the rice is molded into a rice lump having a thickness of 1/2 of the triangle rice balls (Fig. 2).

In the rice ball forming station S6, the die hole 21 of the first turntable 2 and the die hole 31 of the second turntable 3 coincide with each other at a timing coinciding with each other, as shown in FIG. 4. The member 23 rises and pushes the rice lump in the mold hole 21 to the mold hole 31 of the 2nd turntable 3. On the other hand, the 2nd pressing member 16 descend | falls and presses two rice lumps together by the pushing-up member 23 and the 2nd pressing member 16 in this hole 31. As shown in FIG.

The second pressing member 16 is urged downward by the spring 17, and the rice cake is shaped into a triangular rice ball 401 of moderate strength. As described above, each time the first turntable 2 and the second turntable 3 rotate one pitch, a triangle rice ball is formed.

In the onigiri pushing station S7 of the 2nd turntable 3, the pushing member 33 raises in accordance with the stop timing of the 1st, 2nd turntable 2 and 3, and the inside of the mold hole 31 is carried out. The rice ball 401 is pushed up to empty the mold hole 31.

Putting the packing sheet on the rice ball (process of Figs. 21A to 21C)

The pushing member 33 shown in FIG. 4 rises through the belts 42 and 42 of the packaging sheet supply apparatus 4. As shown in FIG. As a result, the rice balls 401 touch the lower surface of the wrapping sheet 200 waiting on the belts 42 and 42 to lift the sheet 200.

As shown in FIG. 3, on the belt 42, the packaging sheet 200 is waiting so that one end may face the rice ball forming station S6 side, and the other end may face the 3rd turntable 7 side. Therefore, the upstream side of the packing sheet 200 is covered on the upper surface of the rice ball 401 by the rise of the rice ball 401 by the pushing member 33. The downstream side of the packaging sheet hangs down from one side toward the third turntable 7 side of the rice ball (Figs. 4, 8A and 21B).

In the embodiment, as shown in Fig. 4, once the lifting member 33 rises higher than the guide plate 61 of the sheet edge stacking device 6, the lower surface of the rice ball 401 is guide plate 61. Descend to a position that matches the height of). Thereby, the edge part by the side of the extrusion block 5 of the packaging sheet 200 is reliably covered by the upper surface of the extrusion block 5. The lowering of the rice ball 401 to a position corresponding to the height of the guide plate 61 is detected by a sensor or the like (not shown) provided on the base 10.

When the rice ball 401 has risen to the maximum, the rice ball 401 once pushes up the pressing member 59. The packing sheet 200 covered with the onigiri 401 is pressed downward by the elasticity of the pressing member 59, and prevents the packing sheet 200 from lifting. Thereafter, the lower surface of the rice ball 401 is lowered until it matches the height of the upper surface of the guide plate 61.

When the lower surface of the rice ball 401 coincides with the upper surface height of the guide plate 61, the rotary arm lever 56 rotates, and the pushing block 5 moves forward to the third turntable 7 side (downstream side).

By the advancing of the extrusion block 5, the onigiri 401 is fitted to the receiving portion 51 of the extrusion block 5, and in the state, the onigiri 401 slides the guide plate 61 to the downstream side. Is returned. The part which hangs down from the onigiri 401 of the packing sheet 200 touches the edge 61a of the guide plate 61, and is sandwiched between the onigiri 401 and the guide plate 61 (FIG. 4, FIG. 8b). Accordingly, the packaging sheet 200 is also covered on the lower surface of the rice ball 401.

That is, the onigiri 401 is sandwiched between the packaging sheets 200 which are bent in a substantially U-shape toward both the upstream sides (see FIGS. 8B and 21C).

Fold over the wrapping sheet edges (process of FIGS. 21D-21F)

In addition, when the onigiri 401 is pressed against the pushing block 5 and advanced to the downstream side, the center portions 200e of both edge portions of the packing sheet 200 touch the pin-shaped obstruction members 60, so that It is folded to the side surface of the extrusion block 5 (FIG. 8C, FIG. 10A, FIG. 21D).

In addition, when the onigiri 401 moves forward, as shown in FIG. 9A, the upper and lower edge portions 200a and 200b of the packing sheet 200 are disposed at upper and lower gaps x1 and x1 of the first regular plate 63. Enter

Next, the upper edge portion 200a of the upper packing sheet 200 touches the inclined edge 64a of the second normal plate 64 and folds downward while moving forward. The folded edge portion 200a passes through the gap x4 between the first normal plate 63 and the second normal plate 64 as shown in FIG. 10B.

Next, as shown in FIG. 9B, the lower edge portion 200b of the packing sheet 200 passes through the gap x2 between the second normal plate 64 and the guide plate 61 to be the third normal. It touches the inclined edge 65a of the board 65, and it is folded upward. The lower edge portion 200b is covered by the second normal plate 64.

The folded edge portion 200b passes through the gap x5 between the second normal plate 64 and the third normal plate 65, as shown in FIG. 10C.

When the onigiri 401 passes through the second normal plate 64, the edge portions 200a and 200b are overlapped on the side surfaces of the pushing block 5. The packing sheet 200 shows the sealing shape which makes the overlap part of this film edge part 200a and 200b the bar part 302. As shown in FIG.

The rice ball 401 and the extrusion block 5 are covered with the packing sheet 200 in the shape of a bag, and then exchanged with the rice lump support frame 71 waiting at the welding station S8 of the third turntable 7. Lose.

Welding operation of both edges of the bag (process of FIG. 21F)

As shown in FIG. 12, the platform 81 descends, and the heater blocks 87 and 87 on the left and right sides of the welding apparatus 8 are both side plates 72 and 72 of the rice lump support frame 71. Located outside of.

The pinion gear 85 rotates so that both heater blocks 87 and 87 approach each other, and the T-shaped heater face 88 on the heater block 87 is the side plate 72 of the rice lump support frame 71. Intrudes into the recess hole 52 of the groove hole 73 and the pushing block 5. The heater face 88 heats and welds the overlapping portions of the package sheet edge portions 200a and 200b.

Both edge portions 200a and 200b are welded, so that the package sheet 200 is formed in the bag 300 having an outer end 301 (FIG. 21F).

Since the bag 300 is formed in the state which covered the packing sheet 200 on the extrusion block 5, the thickness Y1 of both sides of the rice ball accommodating part 51 of the extrusion block 5 shown in FIG. As shown in FIG. 18, it corresponds to the left and right margin Y2 of the bag 300 with respect to the onigiri 401. As shown in FIG.

After welding for a certain time, the pinion gear 85 of the welding apparatus 8 rotates in the opposite direction to the above, and the heater blocks 87 and 87 are separated from the rice lump support frame 71. The welding apparatus 8 rises to the position higher than the rice lump support frame 71 by the lifting of the lifting platform 81. Thus, the third turntable 7 is rotated so that the rice lump support frame 71 can move to the next sealing station S9.

As the lifting platform 81 ascends, the rotary arm lever 56 of FIG. 5 rotates to retract the pushing block 5. The extrusion block 5 exits from the opening 301 of the bag 300 and returns to the standby position on the upstream side.

The rice lump support frame 71 is supported with the onigiri 401 accommodated in the bag 300, and the opening edge 301 of the bag 300 protrudes outward from the outward opening of the rice lump support frame 71. (FIG. 14).

Sealing operation of the sealing opening (process of FIG. 21G)

As shown in FIG. 13, when the rice lump support frame 71 stops at the sealing station S9 by the rotation of the 3rd turntable 7, the press-fit member located in the left and right both sides of this sealing station S9. (Member 98, 98) advances to the rice lump support frame 71 side. The press-fitting members 98 and 98 penetrate through the groove opening 73 of the rice lump support frame 71 and press the bag opening side of the bag portion 302 inward to dent the bag portion 302.

As it is, the lower press plate 91 of the sealing device 9 shown in FIG. 14 raises, and the upper press plate 93 descends. As shown in FIG. 15, the opening edge 301 of the bag 300 is sandwiched by both pressing plates 91 and 93.

In the state of maintaining the above state, the elevating plate 95 is lowered, and the plate-shaped heater 96 on the elevating plate 95 penetrates through the groove hole 93a of the upper pressing plate 93 so that The edge of the opening is heat welded to the cut tape 301 to seal it.

After a certain time of thermal welding, the press-in members 98 and 98 return to their original positions. The elevating plate 95 is raised, the upper and lower press plates 91 and 93 are also returned to their original positions, and the third turntable 7 is allowed to rotate to the next labeling station S10.

Labeling Process

While the rice loaf support frame 71 is stopped at the labeling station S10, the quality indication label printed on the date of manufacture of the rice ball is attached onto the bag 300 by an automatic labeling device (not shown). .

Rice ball discharge process

Next, when the third turntable 7 rotates and the rice lump support frame 71 stops at the discharge station S11, the cylinder 103 of the discharge device 100 shown in FIG. 16 operates to push it. The intake member 101 is pushed outward. The tip end of the pushing member 101 enters from the notch 75 of the rice lump support frame 71, and pushes the onigiri from the outside of the rice lump support frame 71 to the outside.

That is, for every one pitch rotation of the third turntable 7, the rice balls are discharged from the rice lump support frame 71 on the discharge station S11.

In addition, when the third turntable 7 rotates while the pushing member 101 pushes out the packing rice ball 401 to return to the original position, the pushing member 101 is returned when the pushing member 101 returns. 101 collides with the rice ball in the rice lump support frame 71. This causes damage to the rice balls.

Therefore, as a countermeasure, the entire discharge device 100 is elevated by a cylinder (not shown) or the like, and when the rice ball 401 is pushed out, the discharge device 100 is lowered, and at the time of return of the pushing member 101. To raise the discharge device (100). Thereby, collision with the pushing member 101, the rice lump support frame 71, or the rice ball in the said frame 71 can be avoided.

Packaging rice balls

Next, the packaged rice balls are explained.

Since the rice ball is packaged as described above, the cut tape 203 of the outer film 201 of the packing sheet 200 passes from the top of the rice ball 401 to the center of the stool and returns to the back of the rice ball, It returns to the top again (see FIG. 18, FIG. 22A).

In the state where the rice ball 401 is packaged, the sheet-shaped seaweed 206 of the packing sheet 200 is blocked from the rice ball 401 by the inner film 205, and furthermore, by the outer film 201. Is blocked. For this reason, the taste and texture of the laver 206 can be maintained, without being influenced by the moisture from the rice ball 401 or the external air dampness.

When eating rice balls

To unpack the rice balls, one side of the packaging bag 300 is held by one hand, and the rice balls 401 are lightly held on the bag 300. With the other hand, the front end of the cut tape 203 is gripped and pulled to the other end side along the longitudinal direction of the cut tape 203 (see Fig. 22A). The cut tape 203 is separated from the packaging bag 300, and the packaging bag 300 is divided into two.

With the hand torn off the cut tape 203, the other side (opposite side of the holding side) of the bag 300 is pulled out.

Half of the outer film 201 and one film piece 205a welded to the outer film 201 by this half are pulled out, and half of the sheet-shaped laver 206 is exposed (FIG. 23B).

With one hand pulling on one side of the packaging bag 300, the rice ball 401 is supported on the exposed sheet-shaped laver 206, and the other hand is held by the half edge of the bag 300 left by the other hand, Pull it to the side.

The packaging bag 300 is completely removed from the rice ball 401, and only the sheet-shaped laver 206 is covered with the rice ball 401. The onigiri 401 covered with fresh sheet-shaped laver 206 can be eaten.

Since the rice ball can tear off the center part of the width direction of the packaging bag 300 by the cut tape 203, when unwrapping as mentioned above, the rice ball 401 can always be supported by hand. Therefore, as in the prior art, the onigiri 401 can be prevented from falling off from the bag when the packaging bag 300 is torn in two.

In addition, the rice ball 401 may be eaten in the state which half of the packaging bag 300 was covered with the rice ball 401, as shown in FIG. 22B, without removing the packaging bag 300 completely. When the rice ball is eaten on the half of the packaging bag 300, the rice balls 401 are not directly touched and sanitary.

Another embodiment

Description of the said Example is for demonstrating this invention, and does not limit the invention described in a claim. Specifically, another embodiment is shown below.

(Push block)

In this case, as shown in FIG. 20, the onigiri 401 cannot afford to move left and right in the bag 300. Accordingly, the packaging bag 300 serves as a protective member for maintaining the shape of the onigiri 401, thereby preventing the onigiri 401 from being crushed in the packaging bag 300.

In addition, when the packaging bag 300 accommodates the onigiri 401 in such a state that there is almost no room for movement, it is possible to minimize the volume increase of the onigiri. The rice ball 401 is generally displayed on a display case (not shown) when it is commercially available. By making the volume increase of a packaged rice ball small, the number of packaging rice balls displayed on the rice ball display case can be increased.

(Outer film)

23 and 24 illustrate another embodiment of the segmentable portion 202 of the outer film 201 of the packaging sheet 200.

FIG. 23 shows an embodiment in which two cut tapes 203 and 203 are used. The notch 204 is shortly given to the outer side of both cut tapes 203. FIG. Pulling between the ends of the cut tapes 203 and 203 causes the outer film 201 to be torn from the cutouts 204 and 204, thereby dividing the outer film 201.

FIG. 24 forms the outer film 201 into the directional film which is easy to tear in the longitudinal direction, and small notches 204 and 204 are given to the edge part of this film 201. FIG.

Pulling the end 204a between the cutouts 204 and 204 can tear the film apart by the width between the cutouts 204 and 204.

In addition to the above, the dividable portion 202 of the outer film 201 bisects the outer film 201 by hand, using a thread instead of a cut tape, or intermittently notching the so-called cut line on the outer film. It does not matter if it can be configured.

(Interference absence)

25A and 25B show another embodiment in which two obstacle members 59a and 59a with respect to the packaging sheet 200 are provided on both left and right sides of the pushing member 33 in the pushing transition path.

When the pushing member 33 pushes the rice ball 401 in the die | hole 31 and covers the packaging sheet 200 on the upper surface of the rice ball 401, as shown in FIG. 25B, the packaging sheet 200 The left and right edges of the contact portions are pressed against the interfering members 59a and 59a. For this reason, the position can be prevented from being pushed on the onigiri 401 until the packaging sheet 200 reaches the rising end.

In this invention, the food accommodated in the packaging bag 300 is not limited to the said triangle rice ball 401, It may be a rice loaf of another shape, such as a rod-shaped rice. Moreover, it is not limited to a rice lump, Food of various shapes, such as a flat circular shape and a flat square, may be sufficient. The shape of the accommodating part 51 of the extrusion block 5 and the size of the sheet body 2 are suitably determined according to the shape of a foodstuff.

The sheet-like food 207 in the packaging sheet 200 is not limited to the sheet-shaped steaming 206. For example, what is necessary is just a sheet-like food which is satisfactory to fold the packaging sheet 200, such as a seaweed, in the bag 300.

In addition, in the Example, the rice | bowl lump shaping | molding apparatus 1 was linked to the sheet | seat edge overlapping apparatus 6. However, instead of this, the food to be packaged, such as rice ball 401, is manufactured separately, and the food is supplied to the packaging sheet 200, and the process after the food is pushed out by the extrusion block 5 By doing this, food packaging can be efficiently performed. In this case, the food to be packaged to the packaging sheet 200 may be supplied from above the packaging sheet 200.

(Sheet edge first folding device)

In addition, when the edges of the packaging sheet 200 are folded and overlapped by the sheet edge overlapping device 6, the upper edge 200a is downwardly folded after folding the lower edge 200b upward. Can be folded In this case, the clearance relationship between the 2nd normal plate 64 of the sheet | seat edge overlapping apparatus 6, and the guide plate 61 and the auxiliary guide plate 62 is reversed to the above, and the 2nd normal plate 64 of the What is necessary is just to reverse the inclination direction of the inclination edge 64a and the inclination edge 65a of the 3rd normal board 65 from the above.

That is, as shown in FIG. 26A, the second normal plate 64 has a gap through which the upper edge portion 200a of the packing sheet 200 can pass between the upper edge and the auxiliary guide plate 62. x2) is formed, and the upstream portion is overlapped with the outer side of the first normal plate 63. In this overlapping portion, as shown in FIG. 26B, a gap x4 through which the lower edge portion of the packing sheet 200 is bent upward is formed.

The third normal plate 65 has an upstream side overlapping the outer side of the second normal plate 64, and the overlapping portion passes through the overlapping edge 200a of the upper side of the packing sheet 200. A gap x5 is formed. The upstream end of the second normal plate 64 is formed at the inclined edge 64a inclined in the direction in which the upstream side approaches the guide plate 61 gradually, and the upstream end of the third normal plate 65 is gradually upstream. It is formed in the inclined edge 65a inclined in the direction approaching the auxiliary guide plate 62. The operation of folding the edge portions 200a and 200b is the reverse of the above, and the description is omitted.

(Seat edge second folding device)

FIG. 27 is a perspective view showing another embodiment of the guide plate 61 and the auxiliary guide plate 62 of the sheet edge stacking device 6.

(Packing sheet)

35-37 illustrate a packaging sheet 200 of another embodiment. It was developed for detainees who like a slightly damp steamed rice ball.

The sheet-like food 207, such as sheet-like laver 206, is sandwiched between the outer film 201 and the inner film 205 in the same manner as the above-mentioned packaging sheet.

The outer film 201 has a dividable portion 202 composed of two cut tapes 203 and 203 and the like.

The inner film 205 consists of two strip | belt-shaped film pieces 205a and 205a mutually spaced apart. Both film pieces 205a and 205a gather the outer side edges in the longitudinal direction at the side edges in the longitudinal direction of the outer film 201, respectively, and the sheet-like food 207 between the two film pieces 205a and 205a. The strip | belt-shaped opening 209 exposed is formed, and the outer side edge of the outer film 201 and the inner film 205 is welded 208.

The inner end 208a (black portion in FIG. 35) of the welded portion 208 is in contact with the side edge of the sheet-shaped steaming 206. Accordingly, the sheet-shaped laver 206 can support the sheet-shaped laver 206 at the correct position without being pushed in the films 201 and 205.

In the packaging sheet 200 illustrated in FIGS. 35 to 37, the sheet-like lamination 206 is exposed from the strip-shaped opening 209 between the strip-shaped film pieces 205a and 205a of the inner film 205. . For this reason, when the rice ball 401 is packaged in the above-described order, a part of the sheet-like laver 206 exposed from the strip-shaped opening 209 due to the moisture of the rice ball 401 becomes damp.

Therefore, when the package is unpacked, the damp sheet-shaped laver 206 is covered with the rice ball 401.

Conventionally, the on-board rice ball which wrapped the sheet-shaped laver directly on the rice ball was also performed (refer FIG. 39). In this case, however, a step of rolling the sheet-shaped laver into the rice ball and a step of putting the rice ball into the bag with the sheet-shaped laver are required, and the number of steps increases and a dedicated device required for this step is required.

By using the packaging sheet shown in FIGS. 35 to 37 as the packaging apparatus, automatic packaging of the rice ball 401 can be efficiently and hygienically performed.

In addition, the packing sheet 200 shown in FIGS. 35-37 can fold the packing sheet 200 corresponding to the shape of the rice ball 401, and can pack rice ball as shown in FIG. Even in this case, you can eat a rice ball covered with damp sheet-shaped laver.

 Since the packaging device can automatically package food such as rice balls, the packaging efficiency can be improved and the productivity of the packaged food can be improved.

In addition, the packaging of the packaged food can be supported by hand at all times, and the fear of the food falling from the bag can be prevented at the moment when two packaging bags are torn as in the prior art.
