Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a three-dimensional hermetic packaging device for clothing.

(Prior art) Generally, in three-dimensional packaging, clothes 2 suspended from a hanger 1 as shown in FIG. It is designed to protrude from the upper opening 3a, and is mainly used to prevent dust.

However, in this three-dimensional package, since the opening 3a and hem 3b of the packaging bag are open, air enters and exits the packaging bag through these openings, which can sometimes cause mold to grow on the clothes or insects. Sometimes it stuck.

Recently, in order to prevent this, so-called gas replacement, in which the air inside the bag is removed and an inert gas such as nitrogen is introduced, is carried out to remove the air from the packaging bag.
Packaging that seals the opening 3a and the hem 3b (that is, three-dimensional sealed packaging) is performed.

This type of packaging has the effect that mold does not form because the packaging bag is filled with inert gas, and since the packaging bag is sealed, insects do not get attached. be.

Currently, such three-dimensional sealed packaging is carried out as follows.

That is, as shown in FIG. 2a, first, two films are overlapped and the peripheral edge 4c other than the opening 4a and the hem 4b is heat-sealed to form a packaging bag 4.
As shown in FIG. 2b, a suspension member 7 is prepared by integrally connecting two hooks 6 and 6' to the welded piece 5, and this suspension member 7 is attached to the welded piece 5. 2
Opening 4a of packaging bag 4 as shown by imaginary line in figure a
The welding piece 5 of the hanging member 7 is inserted into the welding piece 5 so that the front and back sides of the band 5a shown by the imaginary lines are sandwiched between the inner surface of the opening 4a of the packaging bag 4, and the opening 4a is simultaneously welded to the packaging bag 4 and sealed. I'll keep it.

On the other hand, as shown in FIG. 2c, the clothes 2 are hung on the hanger 1, put into the packaging bag 4 through the hem 4b, and the hook 1a of the hanger 1 is attached to the hook of the hanging member 7. 6', set the three-dimensional package A on the base plate 8a of the vacuum packaging machine 8 as shown in FIG. The packaging bag hem 4b is sealed by heat sealing.

In addition, Japanese Patent Application Laid-Open No. 53-89592 discloses that a packaging tube is sent from the bottom to the top with an assembly frame to package the item to be packaged, and then it is sent to the side to perform vacuum packaging. Packaging equipment is described.

(Problem to be solved by the invention) However, in the currently used three-dimensional sealed packaging as described above, the clothes 2 hung on the hanger 1 are placed in the packaging bag 4, and the hook part 1a of the hanger 1 is suspended. It is difficult to hang the clothes 2 on the hooks 6' of the hanging member 7, especially when the clothes 2 are long, such as coats, and the packaging bag 4 is also long. Since it is difficult to insert the bag up to 6', we currently use a stick of an appropriate length, hang the hook part 1a of the hanger 1 on the end of the stick, put it in the bag, and hang the hook part 1a. In reality, it is hung on the hook 6' of the hanging member 7.

When setting the three-dimensional package A thus obtained on the base plate 8a of the vacuum packaging machine 8, it is necessary to smooth out the wrinkles of the packaging bag 4 and the clothes 2 inside the packaging bag 4, which is troublesome. It's inefficient.

Furthermore, in the case described in the above-mentioned publication, the packaging tube is sent upward from the bottom, so the various devices including this are extremely complicated as an assembly for feeding the tube is required. It had to become something.

In order to solve the above-mentioned problems, the present invention makes it possible to obtain a three-dimensional package of clothes using a relatively simple device, and also provides gas replacement and gas replacement for this three-dimensional package of clothes. The purpose is to make sealed packaging extremely efficient.

(Means for Solving the Problems) In order to achieve this purpose, the present invention provides a cylindrical bag that wraps clothes to be packaged in a suspended state and is pulled down from above. , a heat sealing part for forming the shoulder part adjacent to the cutting perforation blade with the suspension support part of the packaged object in between, and a heat sealing part for sealing the welded piece of the suspension member and the opening of the forming shoulder part. a three-dimensional packaging machine in which the parts and parts are provided at intervals equal to the length of the article to be packaged plus the length of the hanging member;
Adjacent to this, a gas exchange chamber is provided in which the three-dimensional package of the object to be packaged can be stored without losing its suspended posture, and the hem of the three-dimensional package is sealed within this gas exchange chamber. It has a configuration in which it is also equipped with a vacuum packaging machine equipped with a heat sealing section.

As shown in FIGS. 4 and 6, the vacuum packaging machine C consists of a main body 31 and a lid 32 that seals the main body 31, thereby forming a gas exchange chamber D. 32 can be opened and closed by a hinge 33.

The main body 31 is connected at its upper part to the lower part of the machine frame 10 of the three-dimensional packaging machine B.

Therefore, this machine frame 10 is supported by the main body 31 of the vacuum packaging machine C. The main body 31 is provided with a vacuum pump 34 and a nitrogen cylinder 35, and 36 and 37 are their piping. A hook 38 for hanging the three-dimensional package A' is provided in the upper part of the gas exchange chamber D, and a hook 38 for hanging the three-dimensional package A' is provided in the lower part.

7 and 47 are operated by a control device (not shown).

The operation of the three-dimensional sealing packaging apparatus for clothes of the present invention as described above will be explained.

First, to explain the operation of the three-dimensional packaging machine B, the cylindrical bag 15 is rolled up on the winding roll 1 as described above.
4, guided by guide rollers 13, 13, spread by guide rollers 11, 11 and press rollers 16, 16, and hung down, the lower edge 15a of which is first placed in a heat sealing machine as shown in FIG. It is located at position 19. Therefore, the worker attaches the hook 6' of the suspension member 7 similar to the conventional one described above.
The clothes 2 are hung on the hanger 1, and the hook 6 on the hanging member 7 is hung on the hanging hook 18 (FIG. 5).

Next, the operator pulls down the lever holding the cylindrical bag 15 to cover the clothes 2 as shown by the imaginary line, and then activates the heat sealing machine 19. At this time, the welded piece 5 of the suspension member 7 is attached to the heat sealing machine 19.
It is in a position where it is just sandwiched between the hot plate 20 and the receiving plate 21, so when the heat sealing machine 19 operates, the cylindrical bag 15 and the hot plate 20 and the receiving plate 21 are held together. It becomes caught (Figure 4),
As a result, the suspension member 7 is welded to the cylindrical bag 15, and at the same time, the packaging bag 3' for the three-dimensional package is formed.
Furthermore, the opening 3a' of the packaging bag 3' is sealed (see FIG. 8).

At the same time as the heat sealing machine 19 operates, the shoulder forming heat sealing machine 23 and the perforation device 27 located in the head are operated, and as a pre-process for welding by the heat sealing machine 19, the shoulder 3d of the packaging bag 3' is ' is welded and formed, and a perforation 3e' is made above the opening 3a' of the packaging bag 3'.

Therefore, when the opening 3a' is sealed by the heat sealing machine 19, the shoulder 3a' has already been sealed.
d' and perforations 3e' are formed, so that the three-dimensional package A' can be separated from the cylindrical bag 15 when the heat sealing machine 19 finishes sealing the opening 3a'.

Next, the operator separates the three-dimensional package A' obtained by the three-dimensional packaging machine B and which can be separated from the cylindrical bag 15 in a suspended state from the cylindrical bag 15, and holds it and closes the lid. The body 32 is hung from a hook 38 in the gas exchange chamber D of the open vacuum packaging machine C. This work can be carried out efficiently because the three-dimensional packaging machine B and the vacuum packaging machine C are adjacent to each other, and the three-dimensional package A' is separated while being suspended.
This is stored as is in the gas exchange chamber D, so
The suspended posture will not collapse.

Note that the separation work is performed by placing the three-dimensional packaging machine B at the appropriate location [for example, the heat sealing machine 19 and the guide roller 1].
1 and 11] is provided to clamp the cylindrical bag 15, and this can be easily done by clamping the cylindrical bag and pulling down the three-dimensional package A'.

Next, the operator closes the lid 32 and then turns on the start switch (not shown) of the vacuum packaging machine C. This start switch can also be configured to be automatically turned on by closing the lid 32. When the start switch is turned on, a control device that controls the vacuum pump 34 and the solenoid valve is activated.

When the vacuum pump is in operation, solenoid valves 37a and 43a are open, and all other solenoid valves are closed. Therefore, the air in the gas exchange chamber D is exhausted through the piping 37 as shown by the arrow a, and the air is discharged through the actuating device 42 of the heat sealing machine 39.
The hot plate 40 is also located at the rear (on the right side in FIG. 6) because the diaphragm chamber located at the front is sucked through the pipe 43 and the diaphragm is sucked to the rear. After a certain period of time, the solenoid valves 37a, 43a
When the solenoid valve 36a closes, the solenoid valve 36a opens, whereby nitrogen gas flows from the gas cylinder 35 into the gas replacement chamber D through the piping 36. Nitrogen gas fills the gas exchange chamber D, which causes the three-dimensional packaging to
After the packaging bag 3′ of A′ is also filled with nitrogen gas,
Operating section 47 of hem tensioning device 45 for three-dimensional package A'
is activated and the hem 3f' is tightened, and at the same time the solenoid valve 44a opens, thereby allowing nitrogen gas to flow into the diaphragm chamber in the actuating device 42 of the heat sealing machine 39 through the pipes 44 and 43. Due to the inflow of nitrogen gas, the diaphragm protrudes forward, which causes the hot plate 40 to also move forward, causing the hem 3f' of the three-dimensional package A' to touch the receiving plate 4.
1 and the hot plate 40, and are welded and sealed.

Thereafter, the solenoid valve 44a closes and the solenoid valve 48a opens, thereby bringing the gas exchange chamber D to atmospheric pressure. Then, the operator opens the lid 32 and removes the three-dimensional package with nitrogen gas sealed inside the packaging bag 3'.
Take out A′. In addition, while the vacuum packaging machine C performs the gas replacement work and hem heat sealing work as described above, the worker performs the same work as described above using the three-dimensional packaging machine B, and performs the following work in advance. An effective method of using the device of the present invention is to form a three-dimensional package in advance, so that the operator can take out the previous three-dimensional package from the vacuum packaging machine C and insert the next three-dimensional package. , and then repeat the same operation.

(Effects of the invention) As explained above, according to the three-dimensional hermetic packaging device for clothes of the present invention, the three-dimensional packaging machine is a device that manually pulls down the cylindrical bag that covers the garment to be packaged. The configuration is simple, and since the vacuum packaging machine is adjacent to this three-dimensional packaging machine, the operator can stand in front of this machine and between the three-dimensional packaging machine and the vacuum packaging machine to handle the packaging. Three-dimensional packaging of objects and gas exchange sealed packaging can be carried out extremely easily and efficiently, and in order to obtain three-dimensional packages, there is no need to insert clothing from the hem of the packaging bag as in the past. The clothes suspended in the three-dimensional packaging machine can be wrapped by pulling down the cylindrical bag, and the hanging part can be heat-sealed, resulting in a three-dimensional package and the packaged items inside. Since the suspended position is maintained throughout, the product does not lose its shape and there is no need to smooth out wrinkles.Furthermore, the vacuum packaging machine has been changed from the conventional horizontal type to a vertical type, and is installed adjacent to the three-dimensional packaging machine. Because it requires less installation space, it is valuable for small and medium-sized cleaning companies in terms of equipment costs.

In three-dimensional packaging, after the shoulder molding is heat-sealed, the hanging part of this part is heat-sealed, and the difference between the heat-sealed part of the shoulder molding and the heat-sealed part of the hanging part is Since nitrogen gas does not enter between the sealing and packaging operations for gas replacement, the amount of nitrogen gas used can be reduced accordingly. By cutting off the outer part from the removed part, the excess part is eliminated and the overall appearance can be improved.
