Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a packaging method in which a bulb such as a light bulb or a compact fluorescent lamp is inserted obliquely into a packaging box.

[Conventional technology]

Conventionally, there has been a packaging box for tubes as shown in Japanese Patent Publication No. 57-2590. This packaging box will be explained with reference to Figure 6. In this figure, (1) is a tube, and (9) is a tube (1).
(2) is the outer box in which the bottom wall and the top cover member are connected to the side wall aDK, a2 is the tube (1)
This is a shock absorbing fixture for fixing the spherical part of.

A conventional packaging box for tubes is equipped with the above-mentioned parts.

Bend the buffer fixture α into a star shape with four protrusions (12a), insert this fixture into the outer box (2) and support it on the bottom wall of the outer box (2). The tip of each protruding part of the fixing tool (9) is elastically brought into contact with the part, and the spherical part of the tube (11) is held on the concave part formed in the star-shaped center part, and the fixing member (9) is Fitted into the base of the tube (1), these are housed in the outer box (2), and the fixture a and the fixing member (9) provide a buffering effect to the tube (1). .

The conventional packaging box for tubes as mentioned above is a tube (outer box).
2) Since the outer box (2) is stored vertically inside, the volume of the outer box (2) becomes large, and the fixing member (9) for the cap and the buffer fixture for the spherical part are separate from the outer box (2). is necessary,
There are problems of poor packaging efficiency and high cost of packaging materials, and as a means of solving these problems, there is a tube packaging box shown in FIG. 5. In this figure, (1) is the tube, (2) is the outer box, (
5) is the bottom wall, (6) is the extension piece that extends the side wall, (7
a), (7b), (8a), (8b) are extension pieces (
6) is bent and formed inside the outer box (2).

A tube packaging box equipped with the above-mentioned parts is constructed by bending the extension pieces (6) extending from the upper ends of a pair of opposing side walls into the outer box (2) to form a buffer section (7a) inside the outer box (2). , (7b
).

(8a) and (8b), and furthermore, by storing the tube (1) diagonally inside the box along the diagonal line connecting the - corner of the bottom wall (5) and the other corner of the top surface, Tube (
1) No need for buffering and fixing, reducing the number of parts.

Packaging work efficiency can be improved, packaging material costs can be saved, and the packaging volume can be reduced by storing the tube diagonally.

[Problem that the invention seeks to solve]

When the above-mentioned packaging box for tubes is mechanically completed.

When inserting the tube (1) diagonally at a predetermined angle.

For example, as shown in FIG. 3, a suction plate (4) made of an elastic material such as rubber holds the top surface of the tube 110 by suction.

When the tube (1) is tilted at a predetermined angle, the suction plate (4) deforms for tubes with a low center of gravity, making it difficult to obtain the predetermined angle.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method that solves the above-mentioned problems, allows packaging items to be reliably stored at a predetermined angle in a packaging box, and further improves work suitability.

[Means for solving problems]

In the tube packaging method according to the present invention, a packaging box with an open top is placed on a conveyor with the other side end at a predetermined angle in the vertical direction with respect to one side end of the conveyor. The direction of the packaging box is controlled so that the diagonal line on the top surface of the packaging box is perpendicular to the direction of travel, and the packaging box is moved by a conveyor at this angle, and the top surface of the packaging box is oriented at a predetermined angle in the left and right direction.

A tube is inserted into the packaging box, and the tube is stored obliquely along a diagonal line connecting one corner of the bottom of the packaging box and the other corner of the opposing top surface.

[Effect]

In the tube packaging method of this invention, the packaging box itself is tilted at a predetermined angle in the left-right direction so that the tube can be inserted vertically, so that the suction plate that suctions and holds the top surface of the tube is deformed. It is possible to reliably store the product in the packaging box at a predetermined angle without any distortion, and to further improve the suitability of the work.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a side view of a tube packaging process according to an embodiment of the present invention. In Figure 1, (1) is a tube that is the object to be packaged, (2) is a packaging box made of thick paperboard with an open top, and (3) is one side end of the conveyor and the other side end. is a conveyor with a predetermined angle in the vertical direction, and (4) is a suction plate made of an elastic material such as rubber that suctions and holds the top surface of the tube (1).The packaging box (2) is a conveyor ( 3), B is in good condition with the direction of the packaging box (2) being controlled so that the diagonal line of the top surface of the packaging box (2) is perpendicular to the direction of travel, and C is in good condition when the packaging box (2) is placed on the conveyor ( D
11 is a state in which the top surface of the tube (1) is held by suction with a suction plate.
1 shows a state in which the tube (1) is housed diagonally inside the packaging box (2) along a diagonal line connecting one corner of the bottom of the packaging box and the other corner of the top surface.

Next, the packaging process according to the packaging method of this embodiment will be explained. A packaging box (2) with an open top surface is placed on a conveyor (3) whose other side end has a predetermined angle θ in the vertical direction with respect to one side end of the conveyor. , the direction of the packaging box (2) is controlled so that the diagonal line of the packaging box (2) placed thereon is parallel to the traveling direction (state B in the figure). In this state B, the packaging box (2) is placed on the conveyor (
3), the angle θ of the conveyor (3) is given to the packaging box (state shown in figure C), and the tube +11 is suctioned and held by the suction plate (4) (state shown in the figure).
Insert vertically into the opening of the packaging box (2) in state D, release the suction hold of the tube (1) with the suction plate (4) at the specified position, and place the tube (1) in the specified position inside the packaging box (2). Tube with angle θ (1)
(state shown in figure B).

In addition, in this invention, the conveyor is not limited to a series of conveyors, but as long as it can obtain the states of two people, B, C, and E,
Similar packaging methods are possible.

〔Effect of the invention〕

As explained above, in the tube packaging method of the present invention, the packaging box itself has a predetermined angle so that the tube can be inserted vertically. This has the effect that the board can be reliably stored in the packaging box at a predetermined angle without being deformed, and the workability is further improved.
