Description

DETAILED DESCRIPTION OF THE INVENTION The present invention compresses and compresses a laminate of printed materials such as newspapers. Even if the settlement height of the laminate changes, the whole scene of the film is always at the center of the height of the OJ'1 print. The packaging film is sealed with one thread.

The newspaper tC's 4-book printed matter was sent by the newspaper company to the newsagent's store, but the bundle cost 2,400 yen per bundle.
Page and -J-2, (j'Fbef・In addition to the bundles, there are 1.l, iAi several bundles, and what is called an additional bundle.RablThe height of this laminate is constant and 7'x <normal 100-4.OOm,
There are various things between m and a/).

Like this fQ God's j! How is it possible to wrap a bundle of -1.1 length in one machine without 1% of the weight?

The way the first package is made is that it hangs down in late autumn and is on a T-film? 1. Press the laminate against this while compressing the pu, apply the earthwork film on the back side - 2 upper and lower rear sealers, then 1H11 sear 1, cut it, and then seal both sides of it with the upper and lower parts (1i11 side / - Seal laterally with sea.

However, as mentioned above, there are various high caves,
To do this in the same place [1 HIK seal C wear], the specific VLC is that in any J It is best to seal at the center of the reed, and in some cases, it is common to seal from below the height of 1 cld, or from above Cd.

If this happens, the upper and lower fissiles will not fit together accurately, and one of them will be in the wrong position, and if the height of the laminated proboscis is high, it will be impossible to seal.

Saitata Aki 1 rule seal (1 river force/-ru 3 easy combination,

In Fig. 4, the part that is likely to break when the force is applied is part a, but especially the height of Rin (1 river sea ν) and (nl

I,) /).

As mentioned above, if the laminate cannot be sealed when the 1cfi'iJ is high, if the film 11 is widened, the unreasonableness in part a will become thicker.

Therefore, conventionally, the high laminated body of a high official was combined with the rear side seal at the same time.

The invented method addresses the shortcomings of the conventional method in the following way: it is capable of simultaneously performing the rear seal and the side seal, which were previously impossible to perform. It can also be done at the high speed of one packaging machine.
This will lead to increased capacity of 5 units and a reduction in size and weight.

The invented method tracks the movement of the first compression device, and when the device descends, the upper rear sealer follows and descends.
and 1.1 pressure λ When the unit 1 has finished compressing the laminate,
The same sealer is applied to the IF machine at a distance fN such that the distance between the rear side sealer surface of the soil part and the top surface of the laminate is equal to the distance between the lower rear side sealer surface and the lower surface of the counterfeit material, and,
The second compression device fully compresses the 2'i'i layer and moves it forward. Wait until the rear end of the layer passes between the upper and lower rear solar panels, and then raise and lower the 11Ill sealer at the top and bottom, respectively. This invention relates to (2) a method of sealing packaging films for laminates of different heights, in which the main feature of the invention is to always seal the finished film at the center of the height of the laminate.

This will be explained in detail in Figure 1.

In 2i'E l lzu, (2)vi is the first conveyor, above which is installed the 11tev (3) which can be raised and lowered freely, and the laminated 1IA(S) is the 1^1 compression device. (5

If it's history J-11, it's good.

After the Hani 1 compression device (3) finishes compressing the laminate (S), it stops, and at the same time, the previous compound sealer (

The present invention tracks the descent of the first E compression device and
11 sealer follows this, and brush 1 compression device compresses the laminate? When sealing the film, it is placed on standby so that the distance between the upper rear sealer surface and the bottom surface of the laminate is exactly the same, so when the film is rear sealed with the upper and lower rear sealers, It can be done at the center of the height.

However, this is also important; it depends on the stacking height for each item.
] 17 = You can do sea 1 at the center without any problem.

Therefore, the seal can be made with a hole that matches the regular Jill without causing the edge of the film to shift, so it is not unreasonable to perform a one-way seal with V on this rear side seam 2. This allows the film to be sealed without damaging the film packaging.

Similarly to the rear sealer, the side sealer is also transferred using the first compression device to create a rear seal (!
: (+!!l side sealing can be done simultaneously on p;'r, two conveyors, so the equipment can be made smaller and lighter. I can do it.
