JPS5824330B2 - Mochi vacuum packaging method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for vacuum packaging two rice cakes at the same time.

From the point of view of packaging efficiency, it is most preferable to package a large number of mochi in one bag at the same time, but there is a drawback that uneaten mochi may spoil once the package is opened.

However, wrapping one mochi in one bag is inefficient.

In view of the above points, the present invention is designed to package two pieces of mochi in one bag at the same time in an isolated manner, so that even if one side of the mochi is opened, the other side of the mochi remains sealed, thereby increasing packaging efficiency. To provide a method for constructing a packaging form that is easy to use and does not cause leftover mochi to spoil.

The invention may be implemented in an apparatus such as the embodiment shown in FIG.

In this apparatus, a cylinder making process A, a cutting process B, and a sealing process C are performed.

In the above-mentioned tube-making process A, the thermoplastic synthetic resin film F supported in the form of a roll on the shaft 1 is unwound while the tube-making mold 2
The overlapping portions of both side edges of this film F are welded together using a heater 3 to form a tube 4.

In this case, by supplying the cutters at regular intervals from the tip opening 5 of the cylinder-making mold 2, each cutter 6 is removed as shown in FIG.
, 6 . . . are arranged within the tube 4 at regular intervals.

Next, in the cutting process, a pair of bases 7.
Rods 9 and 10 with one end fixed to 8 are connected to a flexible sleeve 11
．． 12, and the flexible sleeve 1
1 and 12 are appropriately pivoted to a frame via pins 13 and 14, so that the base 7.8 moves in a trajectory as shown by an arrow.The specific structure of these bases 7.8 is shown in FIGS. As shown in FIG.

That is, as shown in these drawings, hot plates 15 and 16 are fixed to the front and rear ends of the upper base 7, respectively, and hot plates 17 and 1B fixed to the front and rear ends of the lower base 8 are connected to the hot plates 15 and 16.
I am facing it.

In addition, a cutting blade 19 is installed in the front heating plate 15 at the top.
Perforation blades 20 are buried downward in the hot plate 16 at the same rear position.

As shown in FIG. 3, both bases 7.8 have cam grooves 24°, 25°,
... and each of the cam grooves 24, 25...
One free end of a lever 28, 28, 29, 29 fixed to each drive shaft 26, 26, 27° 27 disposed at the center of the roller is brought into contact with each roller 22, 22, 23, 23.

As shown in FIG. 2, the upper and lower cam grooves 24 and 25 have straight portions of a predetermined length formed on opposite sides thereof, and the other portions are approximately arcuate.

Therefore, when the levers 28 and 29 are rotated in opposite directions by the drive shafts 26 and 27, and the rollers 22 and 23 are rotated along the cam grooves 24 and 25, the upper and lower bases 7.8
moves along a substantially circular trajectory corresponding to the shape of the cam groove 24.25, and at the closest position, the front hot plate 15.17
The tube 4 is moved in a straight line by a predetermined distance while the tube 4 is held between the hot plate 16 and the rear hot plate 16 and 18.

Then, the tube 4 is welded and cut between the cutting edges 6, 6....

However, since the front cutting blade 19 cuts the tube 4 as shown at point X in FIG. 5, the rear perforation blade 20
Form a perforation 30 in the tube 4 as shown at point Y in the figure,
Don't go as far as cutting it.

On the other hand, since the rear heating plates 16 and 18 have a length larger than the width of the tube 4, the perforations 3 as shown at point Y in FIG.
The entire area before and after 0 is sealed 31, 31, but the front hot plate 15
．． 17 is shorter than the width of tube 4, so the fifth
Partial welding 32, 32 is performed before and after the point X in the figure.

Such partial welding 32 is caused by the cutting edge 6 while the tube 4 is being transported.
This has the effect of preventing water from jumping out.

In FIG. 1, the upper and lower bases 7.8 move away from each other after welding and cutting the tube 4, and then repeat the movement of holding the tube again.

As a result, as shown in FIG. 4, a seal 31, 31L and a perforation 30 are formed between the two front and rear grips 6.6, while a temporary seal 32.32 is formed partially at both ends of the tube 4. A bag is formed.

As shown in FIG. 1, in the sealing process C, a conveyor 34 supports a large number of vacuum tanks 35 and rotates.

The tank 35 has a pair of upper and lower parts 35 a that can be opened and closed,
35b, each of which is provided with a pair of hot plates 36, 37 inside.

Then, the bag carried from the cutting process B is placed in the upper and lower members 35a and 35b and sealed, and the air in the tank 35 is sucked through the hole 38 as shown in FIG. The air inside is discharged, and then the hot plate 36,
By squeezing both ends of the bag 4' at 36, 37, and 37, both ends of the bag 4' are sealed.

As shown above, the present invention provides a tube 4 between the front mochi and the rear mochi with a hot plate 15 shorter than the width of the tube 4,
17, and at the same time cut the middle of the weld with the cutting blade 19, the tube 4 between the rear mop and the further rear moiety is longer than the width of the tube 4. Welding is carried out using a large hot plate 16.
A bag 4' is sequentially formed in which two mochi are housed in the front and rear, and the middle is welded 31 through the perforation 30, and both ends are partially welded 32, 32. Since the air in the four bags was exhausted in the vacuum tank 35 in the sealing step C and then sealed, the mochi packaged in this way is similar to the conventional packaging of a large number of mochi in a single bag. Second, it does not allow uneaten mochi to spoil, and it also allows two mochi mochi to be packaged in one bag at the same time, which is more efficient than packaging one mochi in one bag. There is.
