Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a box sheet for enclosing and protecting packaging bags such as fertilizer bags that are stacked on a pallet in the stacked state.

[0002]

[Prior art]

 Conventionally, when many packaging bags such as fertilizer bags are transferred and stored, the packaging bags are stacked on a pallet via a slip sheet so as to have a predetermined three-dimensional shape (or directly on the pallet. They sometimes pile up packaging bags) and transfer and store them with pallets. By the way, depending on the contents of the packaging such as fertilizer, there are some that do not require indoor storage management such as in the warehouse. In that case, these wrapping bags are piled up in an open field, and the stacked wrapping bags are covered with a sheet to prevent dirt due to dust and the like, and to prevent wetness due to rain, snow, etc. ing.

Explaining this, as shown in FIGS. 4 and 5, a slip sheet b having excellent slipperiness is laid on the pallet a at the bottom, and a packaging bag c is formed on the pallet a to have a substantially square planar shape. Such a three-dimensional shape is stacked, and a box sheet d, which is a bag whose bottom surface is open, is covered so as to cover the slip sheet b and the slip sheet b. In the box sheet d, elastic bands f that extend and contract are hooked on each of a pair of side faces e facing each other so as to narrow down, and a through hole h opened at the center of the lower edge of the other side face g. In addition, the rubber band f passed under the slip sheet is hooked (note that only one side is shown in FIG. 4).

[0004]

[Problems to be solved by the device]

 However, with the above method of stopping the box sheet, the lower edge may be rolled up, and dust or water may enter inside from that part.If the slip sheet is used as shown in the figure, this slip There is a problem that the box sheet that hangs on the sheet swells and water easily collects here. There was also the problem that the work of fastening this box sheet would be complicated.

In view of this, in the present invention, it is an object of the present invention to ensure that the box sheets cover the stacked wrapping bags and that the work of fastening the box sheets can be easily performed. The purpose is to ensure protection.

[0006]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above problems, and has a top surface and four side surfaces corresponding to the stacking shape of a plurality of packaging bags stacked in a predetermined three-dimensional shape on a pallet, and the lower surface is opened. Each of the lower edges of the four side surfaces is provided with a highly smooth rope guide along the lower edge skirt portion excluding the lower edge corners of the side surfaces and has ring portions at both ends. A highly smooth rope that passes through the rope guide is provided so that the bag body can be narrowed around the bag body around the four sides, and one rope part of the rope is folded back by inserting the other ring part. The above-mentioned problem is solved by providing a box sheet characterized in that the one ring portion is provided so as to be able to be fastened to the bag body in a tensioned state via an extensible pulling member. It is a thing.

[0007]

[Action]

 In the present invention, by tightening the rope, each rope guide portion through which this rope passes can be narrowed down. Also, since there is no rope guide at the corner portion where the side faces are connected, this corner portion can also be narrowed down easily. Like Further, since the rope guide portion above the lower edge skirt portion is squeezed, when the box sheet covers the packaging bags stacked on the pallet, the lower edge skirt portion will hang on the pallet, Increases air tightness.

[0008]

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in FIGS. In the figure, reference numeral 1 is a box sheet, and the box sheet 1 is a top surface 2 and four sides corresponding to the stacking shape of a plurality of packaging bags c stacked on a pallet a with slip sheets b in a predetermined three-dimensional shape. The side surface 3 is formed, and the lower surface is formed as a waterproof flexible bag body.

Then, as shown in FIG. 2 (FIG. 2 shows a developed state of four side surfaces), the box sheet 1 is arranged so as to extend along the lower edge skirt portion 4 on each of the side surfaces 3. A rope guide 5 which is flexible and has high smoothness is provided above it except for the lower edge corner 6 side of the side surface 3, that is, except for the corner portion. Further, 7 is a rope having a high smoothness, and as shown in FIG. 1, it passes through each of the rope guides 5 and goes around the lower edge. Both ends of this rope 7 have ring portions 8, and the rope 7 is folded back so that the other ring portion 8 is passed through the ring portion 8 located at the corner portion and the other corner portion The loop portion 8 at the tip of the rope is fixed to the through hole 10 of the provided tongue piece 9 through the stretchable pulling member 11.

In use, as shown in FIG. 3, the packaging sheets c stacked with the box sheets 1 are put on the lowermost pallet a so as to hang it, and the rope 7 passed through one ring portion 8 is put on the rope 7. Tighten and squeeze the rope guide 5 of the box sheet 1 so as to wrap the bag c and the slip sheet b. At this time, the corner portion between the rope guides 5 is easily narrowed down because there is no rope guide. Moreover, the lower edge skirt portion 4 is hooked on the peripheral edge of the pallet a so that the airtightness is enhanced. As shown in FIG. 1, for example, the pulling member 11 is composed of a rubber ring 12 and a pair of hooks 13, and is stretched over the ring portion 8 of the rope 7 and the through hole 10 of the tongue piece 9, The rope 7 is kept in a tensioned state.

It should be noted that, in the use of the above-described embodiment, an example is shown in which a pallet covers the packaging bags stacked via slip sheets. Of course, the box sheet of the present invention does not use slip sheets. It can also be used to cover stacked pouches.

[0012]

[Effect of device]

 As described above, according to the present invention, the box sheet is provided with the top surface and the four side surfaces corresponding to the stacking shape of a plurality of packaging bags stacked in a predetermined three-dimensional shape on the pallet, and the lower surface is opened. Each of the lower edges of the four side surfaces is provided with a highly-slip rope guide along the lower edge skirt portion except for the lower edge corners of the side surfaces, and a loop is provided at both ends. A rope with a high smoothness that passes through the rope guide is provided around the bag body around the four sides so that the bag body can be narrowed down, and one loop portion of the rope is inserted through the other loop portion. Then, the one ring portion is provided so as to be able to be fixed to the bag body in a tensioned state via an extendable pulling member. As a result, if the rope is squeezed over the bag, the rope guide is narrowed, and the corner portion is not bulky because the rope guide is not provided. Further, since the rope that has been squeezed is stopped through the pulling member, the operation of attaching and removing the box sheet becomes extremely simple because the stop portion is one place. When the lower edge skirt of the box sheet is hung on the pallet when the rope is squeezed, the airtightness inside the box sheet is increased, and a better condition can be obtained. It is effective.
