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 above object has been attained by providing an apparatus for processing a weakening line, wherein the weakening line is formed on a tape which seals a butt portion of the plurality of flaps. Things.

It is preferable that a plurality of needles are arranged offset in the width direction of the tape.

Further, it is preferable to provide a suction means having a peripheral portion of the needle as a suction port.

[0010]

Embodiments of the present invention will be described below.

FIG. 1 is a side view showing a main part of an embodiment of a weakening line processing apparatus according to the present invention, which is partially sectioned. 2 is an XX view of FIG. 1, FIGS. 3 to 5 are XX views corresponding to FIG. 2 of another embodiment of the weakening line processing apparatus of the present invention, and FIG. 6 is a weakening line of the present invention. It is a perspective view of the box body which processes a line of weakness by a processing device.

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).

The needle 1 is provided with a needle body 11 and a needle holder 12, and the longitudinal direction of the needle body 11 is perpendicular to the side surface P of the box B. 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 weak line processing apparatus of the above embodiment will be described. The box B is conveyed on the roller conveyor so 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.

Further, in the embodiment shown in FIGS. 1 and 2, the tape T is formed by perforating a plurality of needle bodies 11 in close proximity to the needle holder 12 using the needle 1 mounted horizontally. 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 embodiments of the present invention have been described above.
The weakening line processing apparatus of the present invention is not limited to these. 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.
