Abstract

PURPOSE:To obtain an enclosing method with which unsealing or disassembling of a box sealed with an adhesive tape is facilitated, by forming perforations on the adhesive tape along the extending direction of joints after the adhesive tape is sticked to cover the joint on the sealing part on the box. CONSTITUTION:When a box like a cardboard box is packed, the box 50 is transferred to the specified spot by a transfer means 9 and an adhesive tape 15 is fed to the box by a tape feeder 16. And the adhesive tape is applied by a tape adhesion means 21 from the front gable face to the rear gable face along the joints of a cover. After completion of adhesion, the final end of the tape is cut at an appropriate length by a tape cutter 41. After that, perforations 51 are provided along the extending direction of the joint on the adhesive tape sticked on the joint. In this case, even if the center of the adhesive tape deviates from the joint, since the perforations can be made along the joint, such a positional shifting problem can be solved.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a method and apparatus for sealing a box with a lid (herein simply referred to as a box), such as a cardboard box or a box.

[Conventional technology]

Conventionally, when storing the contents in this type of box and packaging it for transport, the lids are butted together using packing adhesive tape such as cloth tape, craft tape, or gummed tape to prevent opening during transport. In general, in order to seal the eyes using the so-called I-stick method, or to integrate two or more boxes into one for convenient loading and unloading onto a truck, the joints of both adjacent boxes are sealed. , It is generally practiced to attach an adhesive tape using the method described in (1) above. In this case, when opening, separating, or disassembling the boxes packed or joined as described above, if no measures have been taken for the adhesive tape, do not hook the ends of the adhesive tape with your nails, etc. The problem is that the joints must be peeled off or broken by strongly hitting the joints with a fist, which is time-consuming and increases worker fatigue. In order to solve this problem, for example, Utility Model Application No. 61-4704
No. 8 and Utility Model Application Publication No. 62-83840 (hereinafter referred to as the first conventional example), perforations are made in advance during production of the adhesive tape, and the adhesive tape is attached to the seam of the box. At the same time, the adhesive tape has two or more rows of perforations in the longitudinal direction of the adhesive tape, which facilitates opening by breaking the perforations, as disclosed in Japanese Utility Model Application Publication No. 57-3642 (hereinafter referred to as the second conventional example). and peel off the part between the rows of perforations when opening the package, making it easier to open the package.
In the conventional example, a part where no adhesive is applied is provided in the center of the tape width, and perforations are made at both ends of the non-adhesive part, and the tape in the non-adhesive part is cut. It is disclosed that the package can be easily opened by peeling it off.

[Problem to be solved by the invention]

However, in the configuration of the first conventional example, the perforation of the adhesive tape was done before the box was packed, so the center of the tape when pasting the tape was at the seam (multiple boxes When the body is integrated, it is easy to shift from the direction (including the joint), and it is difficult to ensure easy opening at all times. Further, in the configuration of the second conventional example, when the box is opened, a large amount of residue of the peeled tape is left behind, which is troublesome to clean up. Furthermore, in the third conventional example, it is necessary to use a special adhesive tape in which adhesive is applied and non-applied areas are formed, resulting in high costs. In order to solve the above-mentioned problems of the prior art, the present invention provides a sealing method and a sealing device that can greatly facilitate opening or dismantling a box sealed with an adhesive tape by adding a simple configuration. The purpose is to

[Means to solve the problem]

In order to achieve the above object, the invention of claim 1 provides that after pasting an adhesive tape to the sealing part of the box so as to cover the seam,
The invention according to claim 2, characterized in that perforations are formed in the adhesive tape along the extending direction of the seam, and a transporting means for transporting the box body in the extending direction of the seam of the sealing part; , a tape feeding means for feeding the adhesive tape toward the box body; a tape sticking means for sticking the adhesive tape from one end to the other end in the extending direction so as to cover the seam; and a tape cutting means for cutting the adhesive tape into a predetermined length, the box sealing device comprising: a tape cutting means for cutting the adhesive tape into a predetermined length; The invention is characterized in that it is provided with perforation processing means.

[Effect]

When packing a box such as a cardboard box, the box is transported to a predetermined location by a transport means, an adhesive tape is sent out toward the box by a tape sending means, and then the adhesive tape is applied by a tape pasting means. Paste from the front gable side of the box body along the seam of the lid to the rear gable side.
After the adhesion is completed, the rear end of the adhesive tape is cut to an appropriate length by a tape cutting means. Thereafter, perforations are made on the adhesive tape stuck on the seam along the extending direction of the seam using a perforation processing means. In this case, even if the center of the adhesive tape is displaced from the seam, the perforations can be formed along the seam, so the problem of such positional deviation can be solved.

Next, the operation of the box sealing device of the present invention constructed as described above will be explained. First, to attach the adhesive tape 15, as shown in FIG. 2, the core of the wound adhesive tape 15 is pushed into the adhesive tape reel 16 and attached. in this case,
The adhesive tape 15 is attached so that when it is pulled out downward from the tape reel 16, its adhesive surface is located on the right side in FIG. 2, that is, its back surface is in contact with the guide roll 19. Ru. Next, pull out the end of the adhesive tape 15 in the drawing direction downward, and then press the warping tool 25 with your finger in the direction of the sticking tool 21 against the return spring 28 to stick the warping tool 25. The warping tool 25 and the holding claws 29a, 2 are rotated clockwise about the shaft 24 until they come into contact with the tool 21.
9b. Next, the drawn-out adhesive tape 15 is inserted into the gap from its tip so that the tip is at the same position as the lower end of the adhesive tape 21. After inserting the adhesive tape 15 into the gap, when the pressing state of the finger against the warping tool 25 is released, the warping tool 25 uses the return force of the return spring 28 to force the rear surface of the central part of the adhesive tape 15 into the holding tab. 29a,
Press it in the direction of 29b. Since the warping tool 25 is formed to have a shorter distance along the width direction of the adhesive tape 15 than the width of the adhesive tape 150, the warping tool 25 is pressed from the back toward the holding claws 29a and 29b. The adhesive tape 15 is held in an arc shape with a concave back side. As shown in FIG. 1, the I-sticking mechanism 12 adjusted in this way is attached to the pillars 11 according to the height of the box to be sealed.
a, llb at an appropriate height position, and adjust the interval between the two guide rails 10 using a guide rail receiver (not shown) etc. according to the width of the traveling box body. . In this adjusted state, unscrew the nut 48 at the end of the shaft 46 to which the cutter 47 is attached, align the shaft 46 to the seam of the lid of the box to be sealed, and tighten the nut. 48 is fixed. Next, when the motor 3, which is the means for transporting the box, is started, the endless rubber belt 9 runs in the direction of the arrow in FIG. 1 via the power transmission chain 6. Therefore, the box placed on the right transfer table 2 is manually moved until a part of the box is placed on the rubber belt 9. Thereafter, when the box moves in the direction of the arrow (from right to left) in FIG. sent to. 4 to 9 specifically explain the subsequent operations. When the top lid is folded, the box body 50 is attached to the side plates 17a, 17.
When sent to the lower part of the front end of the box body 50, the adhesive tape 15 is applied to the front end surface of the abutting part of the upper lid of the box body 50 as shown in FIG.
Since the leading end of the adhesive tape 15 is affixed to the box body 50, the leading end of the adhesive tape 15 is fed out from the adhesive tape reel 16. At this time, the adhesive tape 15 is pressed against the holding claws 29a and 29b in its initial state, that is, before the adhesion is performed, but after the adhesion has started, it warps. Since the tool 25 acts to press against the adhesive tool 21, the holding claws 29a, 29
It becomes possible to easily pull it out from between b. In addition, in this case, the adhesive tape 15 to be attached to the front gable surface
The length of can be changed by adjusting the length of the adhesive tool 21. Next, as the box body 7 is transferred by the running of the rubber belt 9, the adhesive tape 15 affixed to the front end surface is moved to the adhesive tape 21 by the adhesive tape 15.
Since it is pressed to the side, the adhesive tool 21 rotates clockwise about the rotation shaft 22 and tilts as shown in FIG. Thereby, the adhesive tape 15 is pasted along the seam of the lid of the box body 21. Note that the adhesive tape 15 is subsequently rolled up as the box body 7 is transferred, but since the warping tool 25 is pressed against the pasting tool 21 side and squeezed, the adhesive surface of the adhesive tape 15 is pressed against the holding tab. It is impossible for it to adhere to the tools 29a, 29b. On the other hand, as shown in FIG.
When the connecting rod 32 rotates clockwise around , the rotational movement is transmitted to the upper end of the rotational holding member 34 via the pins 31 and 34a, so that the rotational holding member 3
4 rotates counterclockwise around the rotation shaft 35. Therefore, the presser roll 33 at the lower end of the rotary holding member 34 reaches a position corresponding to the top surface of the box body 50, and at the same time, the bow 1 bow length spring 37 is lengthened. Due to the length of the bow, the restoring force of the tension spring 37 is transmitted to the presser roll 33, thereby making the adhesion of the adhesive tape 15 more reliable. After that, when the box body 5o is further transferred, as shown in FIG. 15. Carve a perforation on top. Note that the perforation is continued until the box 50 is further transferred and the contact with the cutter 47 is completed. On the other hand, as shown in FIG. 2, the clipper blade 41 is attached at a position slightly above the lowermost end of the cam 38, so when the adhesive tape 15 is attached to the box body 50, When the top end of the box body 50 is pushing up the bottom end of the cam 38, it does not come into contact with the adhesive tape 15. Note that the clipper blade 41 relative to the cam 38
When the installation position is adjusted, the length of the adhesive tape 15 that is fed out from the rear end of the box body 50, that is, the length of the adhesive tape 15
The length of the adhesive tape 102 affixed to the rear gable surface of the can be changed as appropriate. As shown in FIG. 6, when the cam 38 to which the clipper blade 41 is attached is removed from the rear of the box 50, the clipper blade 41 moves in the direction of the arrow due to the spring force of the second tension spring 44, and the adhesive tape 15 cut. When the adhesive tape 5 is cut by the clipper blade 47, as shown in FIG. The rotation holding member 34 is rotated clockwise by the spring force of the tension spring 37 through the presser roll 33, and the rear end of the adhesive tape 15 is stuck to the rear end surface of the box body 5o. wear. FIG. 9 shows the box 5o on which the adhesive tape 15 has been attached and the perforations 51 have been formed. In this way, when the sealing process to the box body, which consists of one cycle of pasting the self-adhesive tape 15 and carving perforations, is completed,
Subsequently, the same sealing process as described above is repeated for other transported boxes. In the above embodiment, a rotary saw blade-shaped cutter 47 is used as the perforation means, but a needle that moves up and down periodically may also be used. In addition, in the above embodiment, in order to make the drawings easier to read, the pasting mechanism 12 is provided only on the top side of the box body, but it is generally provided on the bottom side of the box body as well. . In addition, in the above embodiment, the box body was a single one, but the first
As shown in Figure 0, the present invention can also be applied to a case where a plurality of box bodies 5o are joined to facilitate loading and unloading onto a truck, for example. In this case, the concept of the sealing part of the seam of the upper cover also includes the joint part of the box body. A cardboard box sealed with I affixed by the box sealing device according to the present invention and a cardboard box sealed with I affixed without the perforation 51 are prepared, and each IKg is sealed from 30 cm above.
As a result of a test in which a weight was dropped onto the I seal seal, it was found that the cardboard box with perforation 51 was opened as planned at the joint opening of the lid, but the box with perforation 51
The cardboard box that was not engraved was not opened.
