Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention mainly relates to a method of stapling (or stapling) for closing the opening of a cardboard packaging box. This invention relates to a stapling method that uses a cardboard box and can close openings at both ends of the box at the same time after accommodating items to be packed.

[Conventional Apparatus] Conventionally, a cardboard box for packaging is made by cutting paper material and stapling it into a cylindrical rectangle with openings at both ends as shown in Fig. 4 (bl), and then this is shown in Fig. 4 (fa). They are crushed and flattened, bundled in large numbers, and sent to customers. Therefore, when packing a large number of items to be packed, prepare a large number of box-shaped boxes by restoring them and stapling only the bottoms in advance, and after placing the items in them, open the only open upper part. The most efficient method is to staple the lid shut.

(Problem to be solved by the invention) However, when adopting such a packaging method,
It is necessary to assemble a large number of packaging boxes prior to packaging, and a large floor space is required for the assembly and storage of empty boxes, resulting in low space utilization efficiency and increased worker movement, reducing work efficiency. There is a problem that causes

[Means to solve the problem]

This invention has been made to solve the above-mentioned problems, and aims to provide a device that assembles a folded cardboard box, simultaneously stores an item to be packed therein, and then staples the box to close it. The item to be packed is placed in a square cylindrical packaging box with openings at both ends, the openings are closed by folding the tongues at both ends, and the packaging box is placed on a moving table with the closed portion facing up and down. It is characterized in that it is supported by a movable table and passes between stapling guns provided at the top and bottom of the movable table, and staples the tongue pieces on both the upper and lower surfaces at the same time.

[Effect]

Immediately before assembling the items to be packed, the folded cardboard box materials that are bundled are returned to their original rectangular shape, and the items to be packed are placed on a moving table with the openings on both sides facing up and down, and the upper and lower stapling guns are used. Finish stapling on both the top and bottom while passing through the gap.

[Example] The present invention will be explained below with reference to the illustrated example. In Fig. 1, numeral 1 is a stapling machine used to carry out the present invention, and the stapling machine is a horizontal stapling machine supported by a plurality of supporting legs 1a, 1b, etc. It consists of a roller conveyor 2 and a pair of upper and lower staple guns 3a and 3b attached to the roller conveyor 2. 4 is a packaging box placed on the roller conveyor 2; 3C13C is a sensor for detecting the moving position of the packaging box 4 attached to the roller conveyor 2; provided.

FIG. 2 shows a control circuit of this stapling machine 1. As shown in FIG. That is, a signal emitted from the relay switch type moving position detection sensor 3c opens and closes the air valve 6 via the microprocessor 5, and supplies the pressurized air stored in the compressor 7 to the upper and lower stapling guns 3a and 3b. and make it work. The staple guns 3a, 3b have generally known structures, and U-shaped staples 8 are driven into the packaging box 4 as shown in FIG. That is, Fig. 3 (a
As shown by l, the staple 8 consists of a thin body part 8a and legs 8b and 8c formed by bending both ends of the body part 8a. It is driven through the eggplant tongue piece 4b.

The hammered legs 8b and 8c are shown in the same figure),
The tip of the push blade 3d is pierced from the side and the staple 8
The leg of the man is bent and the withdrawal is stopped.

Figure 4 shows the order in which the packaging box 4 is used. The material for the packaging box 4 is first made into a square tube with both ends open, as shown in the figure (bl), then As shown in the figure, the box is crushed and bundled and sent to the factory, so after it is restored to its three-dimensional shape and the items to be packed are placed inside, both openings are closed at the same time. 4a is the part that forms the main body of the packaging box. 4b is a lid piece bendably attached to the end thereof.

Next, to explain the stapling method according to the present invention, first, the crushed cardboard box material shown in FIG. 4(a) is restored to a rectangular shape as shown in FIG. The object to be packaged, such as an electronic musical instrument, is housed in the lid piece 4.
b is bent and overlapped with the main body 4a, and then placed on the roller conveyor 2, which is a moving table, with the tongue piece 4b facing up and down.

The packaging box 4 moves on the roller conveyor 2 between the stapling guns 3a and 3b provided above and below, and when it reaches the first position where staples are to be applied, the sensor 3c detects this and operates the air valve 6. , the staples are driven into place by air pressure. In this way, the packaging box 4 is sequentially stapled and reaches the end of the roller conveyor 2.

〔Effect of the invention〕

As described above, in the stapling method according to the present invention, the packaging box 4 is supported on a movable table with the opening facing up and down, and is passed between the stapling guns provided at the top and bottom of the movable table. Since the tongue pieces are stapled at the same time, even though folded packaging box material is used, there is no need to assemble the cardboard box until just before use.
The use of space is highly efficient, and the amount of movement of workers is small, so work efficiency is significantly improved. Furthermore, since the cardboard box is moved on the moving platform with its opening up and down, it has the effect of preventing the lid piece from opening during movement due to its own weight.
