Abstract

PURPOSE:To unpack a corrugated board case without damaging the case and contents by a method wherein the periphery of a lengthwise joint of an outer lid is sucked, a tape lengthwise is cut the outer lid lengthwise with shallow depth, one of the peripheries of the outer lids lengthwise is sucked, the tape of one of the outer lids widthwise directions is cut and further the other tape is cut. CONSTITUTION:With a corrugated board case 1 interposed by a supporting jig 9 from both sides of lengthwise direction 1, the periphery of the lengthwise direction L of outer lids 2, 2' is sucked by a suction device 8 to provide a slit between inner lids and contents. By inserting a cutter into a joint 7 of the lengthwise direction L of the outer lids 2, 2' vertically and sliding it, a tape in the lengthwise direction 1 is cut. With the periphery of the joint of one of the outer lids 2 sucked by the suction device 8, a slit is made between the outer lid 2 and an inner lid 3, a cutter 12 is horizontally inserted into the slit and slid in a widthwise direction S to have the tape in the widthwise direction S of the outer lid 2 cut. The tape in the widthwise direction S of the other outer lid 2' is cut in a similar manner.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for opening an H-bonded cardboard case in which the longitudinal and transverse directions of the outer cover are faced with tape.

[Prior Art J] In the prior art, there have been many methods for opening H-lined cardboard cases that are not reused because the cardboard case may be damaged during opening.

However, at present, there is still no good method for opening the H-covered cardboard case so that it can be used several times after opening, such as when the case is used on a regular basis.

[Problems to be Solved by the Present Invention] Therefore, the present invention seeks to provide a method for cutting and opening only the tape without damaging the H-covered cardboard case and without damaging the contents. It is.

[Means for Solving the Problems] The gist of the present invention is to provide a method for opening an H-bonded cardboard case in which the longitudinal direction and the transverse direction of the outer cover are faced to each other with tape. After sucking up the peripheral edge of the direction seam with a suction device and creating a gap between the inner lid and the contents, the cutter is vertically moved along the longitudinal seam of the outer lid at a depth shallower than the gap. The first step is to cut the tape in the longitudinal direction by inserting the tape and sliding the cutter. Next, the longitudinal periphery of one outer cover is sucked up using a suction device to create a gap between the outer cover and the inner cover. After that, a second step of cutting the tape in the short direction of the one outer lid by horizontally inserting and sliding a cutter through the gap, and further cutting the tape in the short direction of the other outer lid. The third step is to cut using the same method as the second step.
This is a method for opening an H-lined cardboard case, which is characterized by the following steps.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below based on embodiments shown in the accompanying drawings.

Fig. 1 shows an H-labeled cardboard case to be opened according to the present invention, with the outer lids (2) and (2') facing each other in the longitudinal direction (L) and transverse direction (S) with tape (4). There is.

Fig. 2 is an explanatory diagram showing a method of cutting the tape applied in the longitudinal direction (L), Fig. 3 is an explanatory diagram showing the cutting method of the tape applied in the transverse direction (S), and Fig. 4-a. Fig. 4-e is an explanatory diagram showing the unsealing method according to the present invention, and Fig. 4-f=j is an explanatory diagram showing the method of opening the unsealed cardboard case.

(First Step) The cardboard case (1) is first held by the supports (9) from both sides in the longitudinal direction (L) as shown in Fig. 4-a.

Next, as shown in Figure 4-b, the outer cover (2) is removed by the suction device (8).
), (2'') and curve it upward in the longitudinal direction (L) to create a gap between the inner lid and the contents. In this state, cutter (6) as shown in Figure 4-c. the outer lid (2
), (2') by inserting and sliding vertically into the longitudinal direction (L) seam (7), the longitudinal direction (
Cut only the tape L). Here, cutter (6)
The depth of insertion into the seam (7) must be shallower than the gap, so that only the tape can be easily and reliably cut without damaging the inner lid and contents. It can be done. In addition, in the present invention, if the peripheral corner of the outer cover of the cardboard case is cut out in advance as shown in Fig. 2, the tip of the cutter (6) can be rotated in the horizontal direction. The upper end of the cutter is pivotally supported as shown in FIG.
), by inserting the cutter (6) into the notch (5), all you have to do is slide it along the seam (7), and the cutter (6) Insert into seam (7) and tape (4)
can be cut more easily and reliably.

(Steps 2 and 3) Next, as shown in Figures 4-d and 3, one outer lid (2
) is sucked up by the suction device (8) to create a gap between the outer cover (2) and the inner cover (3), and the cutter (12) is inserted horizontally into the gap to cut the short length. Slide it in the hand direction (S) and cut the tape in the short direction (S) of one outer lid (2). Furthermore, the tape in the transverse direction (S) of the other outer cover (2') is also cut in the same manner as in the case of the outer cover (2), as shown in Fig. 4-e.

By the above operations, the longitudinal direction (
The H-attached cardboard case, which is faced with tape in the L) and transverse directions (S), is opened by cutting only the tape.

Further, the H-lined cardboard case opened in the first to third steps above is opened in the following steps.

(4th step) As shown in Figure 4-f, the outer lids (2) and (2') are attached to the suction device (
8) After sucking it up and opening it upward, move the cardboard case so that the guide rod (lO) is inserted below the outer cover as shown in Figure 4-g, open the outer cover, and fold it back downward. .

Similar to the outer lids (2) and (2'), the inner lid (3) is sucked up by the suction device (8) and opened upward.

(5th step) As shown in Figure 4-h, when the contents are stored in a plastic bag (11), the suction device (8) is removed from the plastic bag (11).
), and by adjusting the suction force of the suction device, the peripheral edge of the plastic bag (11) is pulled up and opened as shown in Figure 4-4 while sliding the bag while it is suctioned to the plastic bag. Raise the suction device until Next, as shown in Fig. 4-j, the L-shaped frame (13) is inserted into the polygonal inner side of the upper part of the plastic bag (11), moved horizontally to the outside diagonally of the opening of the cardboard case, and then lowered. Insert the upper part of the plastic bag (11) into the inner lid (3).
Fold outward and downward.

[Effects] As described above, according to the present invention, only the tape can be cut and opened without damaging the H-attached cardboard case, so that the cardboard case can be reused after opening. Moreover, the contents inside the cardboard case will not be damaged.

Fig. 1 is a perspective view showing an example of an H-bound cardboard case to be opened according to the present invention, Fig. 2 is an explanatory diagram showing the first step in an embodiment of the present invention, and Fig. 3 is an embodiment of the present invention. Explanatory drawings showing the second step in the example, and Figures 4-a''j are explanatory drawings showing one embodiment of the present invention.
