Abstract

PURPOSE:To make it possible to pack a long size article with a long size continuous packing material having the same width even if those are different from each other in the length, by applying an adhesive at both side edges of the long size continuous packing material fed to the packing position and by loading the long size article on the packing material cut in a necessary length and bonding the both sides of the packing material. CONSTITUTION:A card board 1 is fed to the position where the front end reaches a catcher 14 and cut off by a cutter 10 operation at the place where it is fed so long enough as to pack a long size article. During said operation, an adhesive is applied by an adhesive applier 11 on the front surface of one side edge of the card board 1 and on the rear surface (margin for paste (a)) of another side edge and four ruled lines (b) are marked at the rear surface of the card board 1 by a roll 12 for marking ruled lines. When a long size article 8 is loaded on the card board 1 to be parallel to the longitudinal direction, the card board 1 is folded at the right and left parts as shown by dotted lines by means of a folder 5 to pack the long size article 8 and bond the part folded together with both edges.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an efficient method for automatically packaging the entire length of pipe rods, shapes, and other long items made of metal or synthetic resin. .

[Conventional technology]

The entire length of the above-mentioned long items is wrapped in cardboard, kraft paper, or other packaging material to prevent the surface from becoming dirty or damaged during transportation or storage, and to prevent rust if the item is made of metal.

The above-mentioned packaging materials generally use a long continuous material wound into a roll, and the packaging material is rolled out from the roll and wrapped around a long object placed parallel to the core of the roll. , and then tape it down or tie it together.

[Problem that the invention seeks to solve]

However, there are standards for roll packaging materials, and the width does not always match the length of the long item to be wrapped.

In addition, since there is a limit to the width of the above-mentioned roll wrapping material, if the length of the long object to be wrapped is larger than the maximum width of the roll wrapping material, the entire length of the long object should be divided into multiple parts. It's packaged. Alternatively, narrow wrapping material is wrapped in a spiral.

Therefore, it takes a lot of time and effort to package ultra-long items, and even if automatic packaging is used, the equipment becomes complicated and inefficient. In addition, the roll packaging material needs to be at least as wide as the length of the long item to be wrapped, so one roll of the packaging material is quite heavy and difficult to handle.

In view of the above-mentioned problems, an object of the present invention is to provide an efficient automatic packaging method that can use long continuous packaging materials of the same width even if the lengths of long items to be packaged are different. shall be.

[Means for solving problems]

In order to achieve the above-mentioned object and solve the conventional problems, the present invention has been made in an automatic packaging method for long articles, in which a long continuous packaging material is fed out toward a packaging position, and during the feeding, the packaging material is removed. At the same time as applying glue to both side edges, if necessary, the packaging material is formed with a fold in the direction perpendicular to the longitudinal direction, and when the packaging material has been fed out to the required length, it is cut at the position corresponding to the rear end and sent to the packaging position. A long object to be packaged is placed parallel to the longitudinal direction of the packaging material on the packaging material at the packaging position, the long object is wrapped in the packaging material over its entire length, and at the same time, both edges of the packaging material are glued together. Then, an automatic tying machine installed at the packaging position is activated to hang the tape or string.

[For production]

The long continuous packaging material fed out to the packaging position is coated with glue on both side edges during the feeding, and has a crease in a direction perpendicular to the longitudinal direction as necessary.

When a long object to be packaged is placed on the packaging material cut to the required length parallel to the longitudinal direction of the packaging material, the entire length of the long object is wrapped in the packaging material and both edges of the packaging material are wrapped. They adhere to each other.

Next, the tape or string is hung around the elongated object wrapped in the packaging material by the operation of the automatic packaging machine.

〔Example〕

Next, the method of the present invention will be explained step by step with reference to drawings showing an example of an apparatus for carrying out the automatic packaging method of the present invention.

In this embodiment, rolled single-sided corrugated cardboard is used as a long continuous packaging material, and packaging is carried out with the core inside. Long items to be packaged include rods, tubes, shapes, etc. Thick items are packaged individually, and thin items are packaged in several pieces.

In FIG. 1, reference numeral 1 is a corrugated board having a width sufficient to wrap around the outer periphery of a long object, and the core has been removed in advance by the width of the glue allowance a along one side edge in the length direction. The corrugated cardboard roll IA is supported by a shaft 2.

A packaging position 3 is set in front of the corrugated cardboard 1 in the direction of unwinding, and a plurality of arch opening/closing automatic binding machines 4 which also serve as packaging stands are lined up at the position in the forward direction of the unwinding of the corrugated cardboard. Furthermore, a cardboard folding machine 5 having a non-slip member such as rubber attached to the portion in contact with the cardboard 1 is arranged between the adjacent automatic binding machines 4 .

An end face folding packaging processing machine 6 is arranged before and after the packaging position 3.

A long object chute 7 is disposed on one side of the packaging position 3, onto which long objects 8 are successively fed in the number of pieces to be wrapped at a time, and are stopped by a stopper 9 to wait.

Between the support position of the cardboard roll IA and the packaging position 3, a cutter 10, a glue applicator 11, and a ruled roll 12 are arranged in this order from the cardboard roll IA side.

A pair of left and right glue applicators 11 are installed so as to simultaneously apply glue to the front side of one side edge of the cardboard 1 and the back side of the other side edge. In the case of the illustrated example, the lined rolls 12 are arranged in four pieces because the cardboard 1 is folded lengthwise into four pieces and packaged in a cylindrical shape with a rectangular cross section.

From the cutter 10 to the front end of the packaging position 3, a pair of guide rails 13 and 1 are located on both left and right sides of the packaging position W3.
3 extends, and a pair of catchers 14, 14, which grip both sides of the tip of the cardboard 1, are attached to the guide rails 13, 14,
13, each of which is movably supported.

1st Step (FIG. 2) The cardboard box is first fed out to a position where its leading end reaches the catcher 14 (see the chain line in FIG. 1). Then, the catcher 1414 pinches the left and right ends of the cardboard 1, and the catcher 1414 grips the guide rail 1313.
along the direction toward the packaging position 3.

Then, when the cardboard 1 is unrolled by a required length A sufficient to wrap the long object 8, the cutter 10 is activated and the cardboard 1 is cut.

While the cardboard 1 is being fed out toward the packaging position 3 as described above, glue is applied by the glue applicator 11 to the front side of one side edge of the cardboard 1 and the back side (glue margin a) of the other side edge. Ru. In addition, four ruled lines are added in the longitudinal direction on the back surface of the corrugated board 1, that is, on the core, by the roll 12.

2nd process (Figures 3 and 4) When the cardboard 1 cut to the required length A comes to the wrapping position 3 and is placed on the automatic binding machine 4, the catcher 14 moves the cardboard 1
is released and returns to the original position (in front of the cutter 10), and the front end and rear end of the corrugated cardboard 1 are gripped by the end face folding packaging processing machine 6.

Third step (FIGS. 5 and 6) When the stopper 9 is lowered, a predetermined number of long sheets Th8 that have been kept on standby are guided to the chute 7 and transferred onto the cardboard 1. When the elongated object on the chute 7 is exhausted, the stopper 9 is raised by -h, and the next elongated object is fed onto the chute 7.

” 2, the long object 8 is placed in the cardboard 1.
When the folding machine 5 is placed parallel to the longitudinal direction of the cardboard (orthogonal to the direction of the creases in the center of the cardboard), the left and right anti-arc shaped arms of the folding machine 5 move to wrap around the cardboard 1 by the rotation of the rollers 5A. The left and right sides of the corrugated pole 1 are bent and raised as shown by the chain lines, and finally the elongated object 8 is wrapped around and the edges of both sides are overlapped and glued together, so that the corrugated pole 1 becomes a rectangular cylinder.

4th culm (Fig. 7) Next, the end face folding packaging processing machine 6 that grips the front end and rear end of the corrugated cardboard 1 is operated, and the end face of the corrugated cardboard 1, which has become a rectangular tube shape, is The folding process is performed as shown below. A label 1 is attached to the end surface, which also serves as a release prevention seal if necessary.
Put on 5.

At the end of the fifth step, the automatic binding machine 4 is activated to wrap tape or string around the prismatic cylindrical package, thereby completing the packaging.

In the above embodiment, a plurality of long objects were packaged separately, but the long objects may be bundled in advance and fed onto a cardboard. In the case of thick and long items, they may be wrapped individually.

The cross-sectional shape of the package may be outside the square shown, hexagonal, or triangular.
It can be any shape such as a square.

Further, instead of cardboard, cardboard, kraft paper or other strong paper, synthetic resin film, etc. can also be used.

In the case of cardboard, it is necessary to use a roller to create ruled lines similar to corrugated cardboard, or a machine to create other creases, but thin paper, synthetic resin film, etc. do not require creases.

=8- If the packaging machine is thick, it is best to glue the two side edges together, but if the packaging machine is thin, the two side edges may be glued together and the glued edges bent.

〔Effect of the invention〕

Since the automatic long article packaging method of the present invention wraps the entire length of the long article according to the above-mentioned process order, the long article continuous packaging machine with the same width can be used regardless of the length of the long article to be packaged. This eliminates the need to prepare in advance continuous packaging materials of various widths that match the length of each long object in preparation for long objects of different lengths, unlike in the past.

Even in the method of the present invention, it is necessary to prepare several types of long continuous packaging materials with different widths depending on the diameter of the long items to be wrapped or the number of long items to be wrapped at a time. Since a common packaging material can be used for long items of different lengths, there is no wastage of packaging materials, and efficient packaging is possible, which is new and useful as an automatic packaging method for long items. .
