Description

The present invention relates to a packing how to pack the object to be packed, which is accommodated in the box body.

  2. Description of the Related Art In order to prevent an article from being damaged or damaged in a transportation stage, an object to be packed is subjected to a buffering process in a packaging stage and packed in a packaging container. In such a packaging container, the heat-shrinkable film is charged into the box, and the heat-shrinkable film is adhered to the inner surface of the box. And heat-shrinks the heat-shrinkable film in this state (see, for example, Patent Document 1). According to this, the object to be packaged is held by the heat-shrinkable heat-shrinkable film so as not to move relative to the box body. The cushioning effect is enhanced by the space provided between the periphery of the package and the inner surface of the box.

JP 2008-30777 A (Page 3, FIG. 2)

  By the way, in the packing line for packing articles in this way, each step is performed by transporting a box body on a conveyor, and an article inspection step is performed after a step of storing an article to be packed in the box body. Generally done. This inspection process is often performed by recognizing the image of the surface of the object to be packed in the box by the imaging device. However, when the packing method as in Patent Document 1 is adopted, the heat shrinkable film is not subjected to heat shrinkage. At this stage, the movement of the packaged goods is not regulated. Therefore, for example, when the object to be packed has a cylindrical shape, the object to be packed may roll, and predetermined information formed on the surface of the object to be packed cannot be accurately read by the imaging device, and the inspection is performed. Cannot be performed reliably.

The present invention has been made in view of such problems, and an object thereof is to provide a packing method that can be inspected reliably be packed accommodated in the box body.

In order to solve the above problems, the packing method of the present invention is:
A packing method for packing an article to be packed contained in a substantially rectangular box,
The packaged object is disposed on a packaging member fixed to the inner surface of the box, and the packaged object is formed by using an adhesive on at least one of inner surfaces of a pair of opposing side surfaces of the box. Temporary fixing step of temporarily fixing
After the temporary fixing step, an inspection step of inspecting the article to be packed,
After the inspection step, the packaging member is heated in a state where both ends of the packaging member are overlapped, and a packaging step of packaging the temporarily fixed object to be packed by the packaging member,
It is characterized by having.
According to this feature, when the object to be packed is accommodated in the box body from above the packaging member, the object to be packed is temporarily fixed to the box body with the adhesive, thereby preventing the movement of the object to be packed when the box body is transported. it can. Therefore, at the time of the inspection process performed before the packaging member is thermally contracted, the imaging device can accurately read predetermined information formed on the surface of the packaged object in the box, and reliably perform the inspection. Can be.

In the packaging step, the packaging member moves the packaged object and releases the temporary fixation between the packaged object and the box.
According to this feature, after the inspection process, the packaged object is moved in accordance with the heat shrinkage of the packaging member in the packaging process, so that the temporary fixation between the packaged object and the box body is released. The trouble of releasing the temporary fixation by the receiving side of the device can be saved.

In the temporary fixing step, the object to be packaged is temporarily fixed by shifting the inner surface of the box toward the widthwise end of the inner surface.
According to this feature, it is possible to secure a moving margin of the packaged object due to the heat shrinkage of the packaging member, and it is possible to reliably release the temporary fixation between the packaged object and the box.

  Embodiments for implementing a packing container, an inspection method, and a packing method according to the present invention will be described below based on examples.

  A packing container, an inspection method, and a packing method according to an embodiment will be described with reference to FIGS.

  Reference numeral 1 shown in FIG. 1 is a packing line for packing an article 2 (object to be packed). The packing line 1 is a state in which the correctly inspected article 2 is stored in the box 3 in a buffered state.

  The packing line 1 includes an adhesive application step (not shown) of applying the adhesive 4 to the bottom surface portion 6 of the box 3, and packaging for fixing the heat-shrinkable film 5 (heat-shrinkable packaging member) to the adhesive 4. A preparation step A, an article storage step B in which the article 2 is placed in the box 3 by disposing the article 2 on the heat-shrinkable film 5, and an inspection of the article 2 stored in the box 3 are performed. The box body 3 is closed through an inspection process C to be performed and a packaging process D in which the heat-shrinkable film 5 is heated and the article 2 is wrapped by the heat-shrinkable film 5. The packing line 1 transports the box 3 to a place where each step is performed by a conveyor (not shown). Reference numeral 10 denotes a packaging container configured by fixing the heat-shrinkable film 5 to the box 3 to which the adhesive member 11 is adhered after the packaging preparation step A.

  The box body 3 is made of cardboard or the like as a base material. As shown in FIG. 2, the box body 3 has a substantially rectangular bottom portion 6 and the same height 4 vertically rising from each side of the bottom portion 6. Each of the side surfaces 7A, 7B, 7C, 7D and the upper surface 8A, 8B, 8C, 8D extending from each of the side surfaces 7A, 7B, 7C, 7D and covering the upper part, form a substantially rectangular parallelepiped.

  As shown in FIG. 3, the heat-shrinkable film 5 used in the packaging preparation step A is a substantially rectangular shape whose shorter direction is slightly shorter than the inner dimension of the box 3 in the shorter direction. In the heat-shrinkable film 5, in the packaging preparation step A, the longitudinal direction thereof is parallel to the longitudinal direction of the box 3, and both ends 5 a and 5 a in the longitudinal direction face the longitudinal direction of the box 3. The lower surface of the central portion 5b in the longitudinal direction is fixed to the bottom surface 6 of the box 3 with, for example, hot-melt adhesives 4, 4 in a state of being located on the side of the pair of side surfaces 7A, 7C.

  Both end portions 5a in the longitudinal direction are hung on the upper surface portions 8A, 8C which are spread outward, and the state where the upper part of the central portion 5b in the longitudinal direction is opened is held, and the box body 3 is placed on the packing line 1. Conveyed.

  As shown in FIGS. 2 and 3, an adhesive member 11 is provided on one inner side surface 9 of a pair of side surfaces 7 </ b> B and 7 </ b> D facing each other in the lateral direction of the box 3. The adhesive member 11 is provided so as to be offset from the center of the inner side surface 9 toward the widthwise end.

  The adhesive member 11 is composed of an adhesive layer 12 (adhesive layer and adhesive of the present invention) having a back surface fixed to the inner side surface 9 and a release material 13 adhered to the surface of the adhesive layer 12. In addition, the adhesive layer 12 is colored with a color having a hue different from the color of the inner side surface 9 of the box 3, has a relatively low adhesive strength, and has a relatively large thickness.

  Further, as shown in FIG. 3, the adhesive layer 12 is formed in a substantially rectangular shape, and is provided such that the short side direction is directed to the width direction of the inner side surface 9 of the box 3.

  In the article storage step B, when the article 2 is stored in the box 3, as shown in FIG. 4A, the release material 13 of the adhesive member 11 is peeled off to expose the surface of the adhesive layer 12. Then, as shown in FIG. 4B, the article 2 is arranged on the longitudinal center portion 5b of the heat-shrinkable film 5 with the article 2 adhered to the adhesive layer 12 (temporary fixing step B1). . Here, description will be made by taking a substantially cylindrical article 2 as an example.

  In the temporary fixing step B1, the article 2 is attached to the adhesive layer 12 by a worker's hand such that predetermined information (the product name described on the label 2a) formed on the surface of the article 2 faces upward. The short side direction is bonded.

  By this bonding, the article 2 is temporarily fixed to the box 3. According to this, the movement and rolling of the article 2 when the box 3 is transported from the article storage step B to the inspection step C on the packing line 1 can be prevented.

  Therefore, in the inspection step C performed in a state before the heat-shrinkable film 5 is thermally contracted as illustrated in FIG. 5, the film is accommodated in the box 3 by the imaging device 20 that photographs from above the box 3. The product name described on the label 2a attached to the surface of the article 2 can be accurately read, and the inspection can be performed reliably.

  Further, as described above, since the adhesive layer 12 is formed to have a relatively large thickness, the adhesive area can be secured even when the article 2 having irregularities on the surface is temporarily fixed, and the box 3 There is little possibility that the temporary fixation will be released when is transported from the article storage process B to the inspection process C on the packing line 1.

  As shown in FIG. 6A, in the packaging step D, both ends 5a, 5a of the heat-shrinkable film 5 are placed in an overlapped state, and the both ends 5a, 5a, which have been superimposed by a bonding means (not shown), are bonded to each other. . Then, the heat-shrinkable film 5 is heated by a hot-air heating device (not shown) in a state where the polymerized both end portions 5a are adhered to each other, and the heat-shrinkable film 5 is thermally contracted. At this time, since there is a space on the side where the article 2 is not located (the right side in FIG. 6A), the article 2 is moved in the direction of the space due to the heat shrinkage (see FIG. 6B).

  As shown in FIG. 6 (b), the article 2 is moved to and held at substantially the center of the box 3 by the heat-shrinkable heat-shrinkable film 5, and the article 2 is stored in the box 3 at the transportation stage. 2 is prevented from moving, and the cushioning action is enhanced by the space provided between the periphery of the article 2 and the inner surface of the box 3.

  As shown in FIGS. 6B and 7, in the packaging step D, the article 2 is moved to the substantially center side of the box 3 with the heat shrinkage of the heat-shrinkable film 5, and this movement causes the article 2 to move. Is peeled off from the adhesive layer 12, and the temporary fixation between the article 2 and the box 3 is released. Therefore, the receiving side of the box body 3 in which the packaging has been completed does not need to release the temporary fixing of the article 2.

  Further, as described above, since the adhesive layer 12 is provided so that the short side direction is oriented in the width direction of the inner side surface 9 of the box body 3, while ensuring the adhesion area between the article 2 and the adhesive layer 12, In the moving direction of the article 2 when the article 2 is moved to the substantially center side of the box 3 by the heat-shrinkable heat-shrinkable film 5, the adhesive force between the article 2 and the adhesive layer 12 is weak, The article 2 is easily peeled off from the box 3.

  Further, in the temporary fixing step B1, since the short direction of the article 2 is adhered to the adhesive layer 12, the article 2 moved by the heat shrinkage of the heat-shrinkable film 5 is peeled off from the adhesive layer 12, and then the adhesive layer 12 is removed. 12 can be prevented from re-adhering.

  Further, as described above, since the adhesive layer 12 is colored in a color having a hue different from the color of the inner side surface 9 of the box 3, the worker accommodating the article 2 can easily recognize the adhesive layer 12. Thus, the article 2 can be securely adhered to the adhesive layer 12.

  Further, as described above, since the adhesive member 11 is provided so as to be shifted from the center of the inner surface 9 to the end in the width direction, the article 2 is formed by the heat-shrinkable heat-shrinkable film 5. 9 is moved from the end in the width direction to the center. Therefore, the allowance for the movement of the article 2 by the heat-shrinkable heat-shrinkable film 5 can be secured, and the temporary fixation between the article 2 and the box 3 can be reliably released.

  Further, as described above, since the surface of the adhesive layer 12 is covered with the release material 13, for example, when the article 2 has a shape that is difficult to roll and does not need to be temporarily fixed, the release material 13 is left attached. Accordingly, it is possible to prevent the article 2 from being unnecessarily adhered to the adhesive layer 12. Therefore, this packing container 10 can be used regardless of the necessity of temporary fixing.

  In the above-described embodiment, for convenience of explanation, the number of the articles 2 accommodated in the box 3 is described as one. However, a plurality of articles are generally accommodated in one box 3. It is a target. In this case, of the plurality of articles, the article that needs to be temporarily fixed is adhered to the adhesive layer 12, and the other articles are accommodated in the box 3 without being temporarily fixed, and are heat-shrinkable by the heat-shrinkable film 5. All articles are packaged together.

  In addition, assuming that there are a plurality of articles that need to be temporarily fixed among a plurality of articles housed in the box body 3, for example, a pair of side surface sections 7 </ b> B opposed in the short direction of the box body 3. , 7D may be provided with a packaging container provided with a plurality of adhesive layers 12 respectively.

  As described above, the embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention, they are included in the present invention. It is.

  For example, in the above-described embodiment, the mounting of the adhesive member 11 is performed before the packing line 1 and after the assembly of the box body 3 in another place, and is not included in the packing line 1. 1 and may be performed before the packaging preparation step A, or may be performed after the packaging preparation step A and between the temporary fixing step B1.

  Further, a configuration in which the packaging preparation step is not included in the packaging line 1 may be performed. For example, the packaging preparation step may be performed at another location together with the attachment of the adhesive member 11.

  Further, the adhesive member 11 in the above-described embodiment is constituted by the adhesive layer 12 and the release material 13, and the surface of the adhesive layer 12 has a constant adhesive force. However, the present invention is not limited to this. May be constituted by a pressure-sensitive adhesive layer so that the article is adhered only when the article is strongly pressed, so that a release material is not required.

  Prior to the article storing step B, the box 3 is not provided with the adhesive member 11, and in the article storing step B, the worker applies an adhesive having a relatively low adhesive force to the inner surface 9 of the box 3 or the article 2. A mode in which the article 2 is applied and the article 2 is temporarily fixed to the box 3 may be used.

  Further, the adhesive member 11 is not limited to the configuration in which the adhesive member 11 is provided to be offset from the center of the inner side surface 9 to the width direction end side. In step B, the worker may attach the article 2 from the center of the inner side surface 9 toward the widthwise end.

  Further, the box body 3 is made of cardboard as a material, but may be made of, for example, a plastic having excellent durability.

  Moreover, in the said Example, although the heat-shrinkable film 5 demonstrated the aspect arrange | positioned so that the longitudinal direction might become parallel to the longitudinal direction of the box 3, it is not restricted to this, The heat-shrinkable film 5 You may arrange | position so that a longitudinal direction may become parallel to the short direction of the box body 3. FIG.

  Further, the box 3 is not limited to a substantially rectangular shape in a top view, and may be a substantially square in a top view. In this case, the short direction of the heat-shrinkable film 5 is slightly shorter than the inner dimension in the width direction of the box. It is formed.

  In the inspection process C in the above-described embodiment, the article 2 is specified by reading the product name described on the label 2a with the imaging device 20, but the present invention is not limited to this. For example, the article is identified by the contour or pattern of the article. The item may be specified, or a barcode reader may be provided instead of the imaging device, and the item may be specified by reading a barcode written on the item.

  In the above embodiment, as shown in FIG. 6, the adhesive 4 for fixing the heat-shrinkable film 5 to the box 3 is located vertically above the adhesive layer 12. 4 may be arranged on the center side of the inner side surface 9 with respect to the adhesive layer 12. According to this, since the article 2 moved by the heat-shrinkable heat-shrinkable film 5 moves to the center side from the adhesive 4, the article 2 moves to the width direction end side of the inner side surface 9 from the adhesive 4. The article 2 is easily peeled from the located adhesive layer 12.
