DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weakening line processing apparatus, and more particularly to a weakening line processing apparatus for processing a weakening line on a tape which seals a butt portion of a flap of a box body. It is.

[0002]

2. Description of the Related Art As a conventional technique relating to a step-opening apparatus for a corrugated ball related to a weakening wire processing apparatus, there is Japanese Utility Model Publication No. 7-1657.
No. 8 is known.

The prior art described in the above publication is described in Japanese Utility Model Publication No. Hei 7-16578, in which the cutting peripheral portion of a corrugated ball box is pulled outward by a suction device. There is described a step-ball opening apparatus in which a step-ball box is cut vertically by a (rotation) blade.

[0004]

However, the above-mentioned prior art has the following problems.

That is, in the corrugated ball opening device disclosed in Japanese Utility Model Publication No. Hei 7-16578, a weakening line is formed on a tape which seals a butt portion of a flap of a box body. Can not.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a weakening line processing apparatus for processing a weakening line on a tape which seals a butt portion of a flap of a box body.

[0007]

SUMMARY OF THE INVENTION The present invention provides a transporting means for transporting a box, a needle which is advanced and retracted with respect to a surface formed by a plurality of flaps of the box which are abutted, and a needle which is advanced and retracted. The width of a tape on which the needle seals over the butted portion of the plurality of flaps.
The above object has been achieved by providing a weakening line processing device, which is provided with a plurality of staggered lines, and processes weakening lines on the tape .

[0008]

[0009] It is preferable that the peripheral portion of the needle and a suction means for the suction port.

[0010]

Embodiments of the present invention will be described below.

[0011] Figure 1 is a side view showing an important part of an Example of weakening beam machining apparatus of the present invention is shown partially sectioned. 2 is an XX view of FIG. 1, FIGS. 3 to 5 are XX views corresponding to FIG. 2 of another embodiment and an embodiment of the weakening line processing apparatus of the present invention, and FIG. It is a perspective view of the box body which processes a weak line by the weak line processing apparatus of the invention.

In these drawings, reference numeral 1 denotes a needle which advances and retreats with respect to a (side) surface P formed by a plurality of butted flaps F of a box B conveyed by conveying means (not shown); This is suction means having a suction port 21 at a peripheral portion of the needle 1, and a weakening line (perforation) is formed on a tape T which seals a butt portion G of a plurality of flaps F. . The needle 1 is advanced and retracted at right angles to the side surface P by an advance and retreat means (not shown).

[0013] With reference to each part of the reference example, the needle 1 comprises a needle body 11 and needle holder 12, with the direction perpendicular to the side surface P in the longitudinal direction of the box B of the needle body 11, The distal end of the needle main body 11 is arranged so as to have the same height as the height of the abutting portion G of the plurality of flaps F, and the needle holder 12 is moved in the direction perpendicular to the side surface P of the box B by the reciprocating means. The needle body 11 is moved forward and backward.
Are moved forward and backward at right angles to the side surface P of the box B. The advancing / retracting means, not shown, can be achieved by a known technique such as, for example, a solenoid or mechanical reciprocation of the needle holder 12. Further, an elevating device for the needle main body 11 and the needle holding body 12 may be provided so that the distal end of the needle main body 11 can be moved up and down according to the height of the butted portion G.

The suction means 2 is provided with a vacuum box 22 having a suction port (vacuum pad) 21 around the needle 1 and a vacuum pump (not shown) for exhausting air in the vacuum box 22. The air in the vacuum box 22 is exhausted by a vacuum pump in the direction of the arrow in FIG.

The transport means not shown may be configured so as to be able to transport the box B in a direction along the side surface P of the box B, and can be achieved by a known technique such as a roller conveyor. can do.

Next, the operation of the weakening wire processing apparatus of the above-described reference example will be described. The box body B is conveyed on the roller conveyor such that the surface P formed by the two butted flaps (upper flap and lower flap) F is a side surface in the traveling direction, and the two butted flaps are brought together. Butt G of two flaps (upper flap and lower flap) F
When the front end of the needle body 11 in the traveling direction reaches the position of the tip of the needle body 11, the box B is conveyed while the tip of the needle body 11 is advanced and retracted at a high speed in a direction perpendicular to the side surface P of the box B. (The tape T is moved), so that the tape T sealing above the butted portion G of the two butted flaps (the upper flap and the lower flap) F has a weakened line (the cut line). A fine perforation having such a pitch is processed.

Since the tape T located at the peripheral portion of the needle body 11 is sucked toward the needle holder 12 by the suction means 2, the tape T enters the inside of the butting portion G. Even if it is deformed so that it escapes, the perforation can be reliably processed.

In the reference example shown in FIGS. 1 and 2, a plurality of needle bodies 11 are closely perforated using a needle 1 in which a plurality of needle bodies 11 are mounted in close proximity to a needle holder 12 to form a tape T. Can be substantially cut. When the box B reaches the position of the tip of the needle body 11 by the transport means, the needle 1 is moved in the horizontal direction while moving the needle 1 in the horizontal direction without moving the box B. It may be. Further, the needle 1 may be made to reciprocate obliquely with respect to the side surface P instead of at right angles.

If a weakening line (perforation) is formed on the tape T sealing the upper part of the butted portion G, Patent 2
The box B can be unpacked by a box unpacking device described in 596844.

The reference embodiment of the present invention has been described above.
In the apparatus for processing a line of weakness according to the present invention, for example, as shown in FIG. 3, the suction port (vacuum pad) 21 of the suction means 2 may be formed in an oblong shape in the vertical direction.

As shown in FIG. 4, a plurality of (three) needles 1 are provided in the horizontal direction, and a suction port (vacuum pad) 21 of the suction means 2 is formed in an oblong shape in the horizontal direction. Is also good.

As shown in FIG. 5, a plurality (3) of the needles 1 are displaced in the width direction (vertical direction) of the tape T, and each of the needles 1 is attracted to each of the needles 1. The mouth (vacuum pad) 21 may be formed in an oblong shape in the vertical direction. By disposing the plurality of needles 1 in the width direction of the tape T, even if the position of the butting portion G is shifted due to deformation of the box B or the like, any one of the needles 1 is displaced. By using 1, the weakening line (perforation) can be reliably processed at the position above the butted portion G of the tape T.

[0023]

As described above, the apparatus for processing a line of weakness according to the present invention is capable of processing a line of weakness on a tape which seals on a butt portion of a flap of a box.
