Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coating method for coating at least the upper part of an article with a film.

For example, when packing a refrigerator or washing machine in a cardboard box, Styrofoam is inserted as a cushioning material. In this case, if Styrofoam is welded to the surface of a refrigerator or the like, this will have an adverse effect on the surface. Furthermore, products such as refrigerators must be dustproof and waterproof. For this purpose, as shown in Fig. 1, at least the upper part of the article (1) is covered with a film (2), a polystyrene foam is inserted into this film (2), and then the film (2) is used to prevent dust. , to make it waterproof.

Conventional wrapping method (as shown in Figure 1g2), a film (2) fed by rollers (4) is placed on top of the article (1) coming up the conveyor (3) from above, and then the article (1) The sealing device (5) seals the 10 film (2) above the upper surface of the cutting device N (6
) is cut. According to such a conventional method, since the film (2) is supplied from above, the vertical height of the equipment is extremely restricted, and as a result, the installation location is restricted and maintenance and inspection cannot be easily performed.

As shown in Fig. 8, a cylindrical film (2) is used as the film (2).
) becomes larger in plan view, the film (2
) cannot be covered. In other words, it is possible to cover almost only one type of article (1) with the Yuzujiku film (2), and therefore, articles (1) of various shapes can be coated on the flowing sea.
This means that it cannot be adopted in the

The purpose of this investigation is to reduce the height of the equipment,
A further object of the present invention is to provide a method for handling articles of various shapes.

In order to achieve the above item 1, the covering power method in the present invention covers at least the upper part of the article with a film.
Fold each side of the film into a double shape using the N method and cut the film in the center of one side, with the cut facing downward and supply it to the public. , then,
The film with its tip sealed is spread out with both sides hanging down against a horizontal curved surface, and then the article is fed into the film so that the front surface is in contact with the sealed part, and The front packing film is sealed and cut from the left and right directions on the rear side of the article.

According to this decimal method, the following effects can be expected. 1. In other words, since the film is fed horizontally, the height of the equipment can be reduced to just a little higher than the maximum height of the product, which allows for a compact overall structure. In addition, since the articles are supplied and sealed within a long film spread out in a portal shape, even if the articles have different shapes in plan view, the upper part of these articles can be covered with the film. Therefore, it can be easily adopted even in lines where articles of various shapes flow.

An embodiment of the present invention will be described below based on FIGS. 4 to 8. QQ is a film, both sides (10a) (10a
) Fold 1 and make a double shape, and put 2 (
It is preliminarily wound up into a roll in a state having the lth (11). A roll-shaped film 01 is disposed on the side of the conveyor α that supports and conveys the article (6), and is guided above the conveyor θ through a plurality of guide rollers α and tension rollers. From there, the paper is fed in the longitudinal direction along the conveyor with the cut line downwardly positioned, and reaches a pair of upper and lower supply rollers. A box frame-shaped guide frame (B) is provided at the door of the feed roller θ4, and this guide frame 0'I)
The conveyor (g) passes through the lower part of the inside. The guide 71
There are bins (18A) (18B) at the top of the rear end of the gnome 0η.
Left and right lever (19A
) (19B) is extended rearward, and a similar left-right lever (20A) is installed at the lower rear end of the guide frame θη.
(20B) is attached via the bottles (21A) and (21B). Each left and right lever (19A) (19B) (
The vertically opposing free ends of 2OA) (20B) are integrated by cylindrical connecting members (22A) (22B), thereby forming a pair of left and right swing frames (28A) (28B). There is. ⑼ is a drive device that swings both swing frames (28A) (28B) toward and away from each other (swings open and close), and an operating lever (25A) (25A) ( 25B) and these operating levers (
! 5A) (to a cylinder device connected between the free ends of 25B). The swing frame (,28A>623B)
Interval 1. A membrane Q* (a stretching device for stretching the D sea/L/ section in the vertical direction) is provided.

In other words, the connecting member (22A) (2
Lifting lever (29A) attached to the upper end of 2B) so as to be able to swing up and down via the front and back bins (28A) (28B)
(29B) and these lifting levers (29AJ (2
9B) and a pulling body 00 attached to the connecting bottle 9B).

Seal the bottom of the swing frame (28A) (28B,).
(in the cutting device) is provided. In other words, the seal/cut device (2) consists of a receiver provided on the - side (on the stand) and a hot blade (2) provided on the other side, and these cll (2) are grooved so that they can approach and separate from each other. .

The film OI, which is wound into a roll with both sides (10a) (10a) folded into a double shape and with a cut 0υ in the center of one side, is guided by each roller α◆0→ while being pulled out. , and above the conveyor (2), the cut 0υ is positioned downward, and the feed is fed along the length of the conveyor α, and the supply roller OQ
leading to. This film θQ has both sides (10a)
(16a-) is transported while being guided by the side surface of the guide frame 025, and therefore the film θQ
From the position exiting the supply roller OQ, both sides (IQa) (10a) on the negative surface side are automatically expanded in a hanging shape with respect to the other upper horizontal surface. Before carrying out the loading work, as shown in Fig. 5, the tip of the IIJ (this is the seal part (A) produced in the previous process) is formed. Also, the operation of the drive device (C) The two working frames (28A) and (28B) are opened and moved, and the lifting levers (29A and 29B) are stretched horizontally, and the pulling body C++> is in the lowered position. The front end of the ``C film θ() is in a state where its front side is closed so that the sealing part (A) is located in the center in the vertical direction.In this state, the conveyor 0
1 transports the article θ'4, this article 0'4 passes through the guide frame a',
) C28B), and its front surface contacts the seal '4(A) side.

Then, as the article is further conveyed, the film θQ is pulled out in a hooked state. @
As shown by the solid lines in Figures 6 to 8, when the rear surface of the article passes the seal/cut device), the conveyor (
13 is stopped. Then the drive device (c) is activated,
As shown in the imaginary lines in FIGS. 6 and 7, the connecting member (22A
) (22B) close the l1IiI swing frames (28A) (2flB) so that they approach each other. As a result, both the lifting levers (29A) (29B) move upward around the bins (28A) (28B) in the longitudinal direction, and the lifting body rises as shown in the phantom lines in FIGS. 6 and 8. C(
◇ pull up the center of the upper horizontal part of the film trowel and expand the part corresponding to the seal cut device (to) in the vertical direction. Next is the seal cutting device I! ), and the above-mentioned f extension parts are moved closer to each other.
and heat (b) to seal and cut as shown in the imaginary line in FIG. This creates a new seal (A). Sealing in the expanded state like this means
The sealing surface can be cleaned and a sacrificial seal can be made possible. By the above operations, the film (19) can be coated on the upper part of the article 0'4, and this article (roll) is conveyed backwards.Then, the receiver separates the table (c) and the thermal power (2),
Then, by opening both swing frames (28A) (28B), the state returns to the state before the work shown in figure m5.

In the examples (drawings), a transparent film is used, but it can be translucent or opaque.Also, a cylindrical film can be used as a roll. Then, at the top of the supply roller 0, the center part of the lower layer may be cut with a cutter to form a cut Qυ.
It is also possible to cover almost the lower part of the side surface of No. 4.
