A gap formed between the workbench 5 and the rotating plate 6 is used as an outlet 12 through which the strip film 4 is drawn out.

Reference numeral 13 denotes an electric heating blade located between the rising portions 8 and 9 and disposed within the rotating plate 6, and is exposed to the outside through the gap 11 when the rotating plate 6 rotates downward. There is.

14 is a molded cloth fixed to the rear surface of the rising portion 10 of the rotating plate 6 (see FIG. 4), and 15 is a roller rotatably pivoted below the outlet 12. In the state shown in FIG. 1, it is in contact with the cloth 14.

Now, reference numerals 16 and 16 are support arms whose respective proximal ends are rotatably supported on the left and right side walls 1a and lb of the main body case 1 via fulcrum shafts 17 and 17. They are connected by a connecting arm 18 to form a generally U-shape as a whole.

Reference numeral 19 denotes an article mounting table formed by bending an iron plate into an L-shape, for example, and the lower end of the base plate 19a is connected to the connecting arm 1.
The fulcrum shaft 17 is fixed to the central part of the
It is provided so that it can rotate in the vertical direction using the fulcrum as a fulcrum.

The housing is 20° 20, and each proximal end is connected to the support arm 16.1.
It is a plate-shaped support arm that is rotatably supported at the middle part of 6, for example, via a pole 21. A roller receiving portion 20b is bent outward at a lower part of the intermediate portion.

Reference numeral 22 denotes an electric heating panel having a heater (not shown) disposed on its back surface, for example, and has a concave portion 22a slightly wider than the article mounting table 19 formed in a central portion thereof facing the article mounting table 19 from below. There is.

Thus, the electric heating plate 22 is mounted and fixed between the mounting parts 20a of each of the support arms 20, and the roller receiving part 20b of the support arm 20 is mounted on the row 223 pivotally mounted at the lower part of the main body case 1. It is supported by contact.

Also, the portion of the support arm 20 located between the roller 23 and the electric heating plate 22 and the left and right sides i1a and lb of the main body case 1
A tension coil spring 24 is stretched between the lower end of the lower end of the lower end of the lower end of the lower end of the row 223 and the front side (left side in FIG. 1).

Therefore, in the above configuration, when the article mounting table 19 is pressed downward, it is rotated downward about the fulcrum shaft 11,
In conjunction with this, the base end of the support arm 20 is rotated downward via the bolt 21, and as a result, the support arm 20 is rotated about the roller 23 as a fulcrum while slightly sliding on the roller 23, thereby generating electric heat. The board 22 rotates upward, and the article mounting table 19 comes to be recessed into the recessed part 22a of the electric heating board 22.

When the pressure on the article mounting table 19 is released in the taut state, the electric heating plate 22 is rotated downwardly by the spring force of the tension coil spring 24, and the article mounting table 19 is rotated upward again.

Next, the function and usage of the above structure will be described.

First, the winding end of the strip film 4 is inserted between the roller 15 and the cloth 14 and led out from the outlet 12.

Further, a switch device (not shown) is turned on to heat the electric heating blade 13 and the electric heating plate 22.

Then, the article A to be packaged is placed on the workbench 5, and the band-shaped film 4 is pulled out to an appropriate length and placed on the upper surface of the article A, and the leading end of the film 4 is moved from the rear end of the article A. Make sure to wrap it around the bottom.

Then, when the article A is lifted and moved forward together with the film 4 and the film 4 is strongly pulled forward, the strip-shaped film 4 comes into close contact with the upper surface of the rising portion 10, and due to this adhesion force, the strip-shaped film 4 is moved to the film cylinder 2. As well as being in a state of tension with further withdrawals being prevented,
The rotating plate 6 rotates downward about the pivot axis γ, and this rotation exposes the electric heating blade 13 from the gap 11.

In this state, as shown in FIG. 4, the strip-shaped film 4 is wound in the front-rear direction of the article A, the winding start end and the winding end of the film 4 are overlapped at the bottom of the article A, and then the article A is wrapped around the article A. Move it further down.

Then, the band-shaped film 4 comes into contact with the electric heating blade 13 and is cut by melting.

After this, the article A is placed on the article mounting table 19, and in this state, the article A is placed on the belt-shaped film 4 surrounding the article A.
Fold into the bottom of part A while pulling the protruding parts from both left and right sides to the left and right to create tension.

Then, when the article A is placed on the article mounting table 19 and pushed down, the article work table 19 rotates downward, and in conjunction with this, the electric heating panel 22 is rotated upward 1, and the bottom surface of the article A is placed on the electric heating plate 22.
A strip-shaped film 4 on the lower surface of the article A in pressure contact with the upper surface
The polymerized portion of is welded, and packaging of article A is thus completed.

When the packaged article A is removed from the article workbench 19, the article workbench 19 is released from its pressure and rotates upward again, and at the same time, the electric heating plate 22 rotates downwardly again.

According to this embodiment configured in this way, when the article A is placed on the article placement table 19, the portions of the strip film 4 wound around the article A that protrude from both left and right sides of the article A are removed. The work of folding into the bottom of the article A and the work of welding the overlapping part of the strip film 4 at the bottom of the article A can be done consistently and easily, and it goes without saying that the packaging speed can be improved compared to the conventional method. It is possible to dramatically improve the efficiency of the packaging operation, such as by reducing the fatigue caused by the operation, and it is even more convenient when the article A is heavy or has a shape that is difficult to hold.

In particular, according to this embodiment, since the electric heating plate 22 is rotated upward in conjunction with the downward rotation of the article placement table 19, the rotation stroke of the article placement table 19 during packaging work can be reduced. This is very convenient as it can also improve the packaging speed.

In the above embodiment, the article mounting table 19 and the electric heating plate 22 are configured to be moved up and down by rotation, but they are not limited to this and may be moved in parallel up and down by sliding or the like, and may be arranged in six positions.

The thin ice device is not limited to the embodiments described above and shown in the drawings, but can be modified and implemented as appropriate without departing from the gist of the invention.

As described above, the present invention can significantly improve the packaging work efficiency and provide a packaging device that is extremely convenient in practice.
