  By the way, in general, in order to ensure the stability during transportation (conveyance) of a loaded product mounted on a pallet, for example, as shown in FIG. 7 of Patent Document 1, a binding band, a stretch film, a string It is necessary to fix the goods to be shipped by using a bundling member such as. However, in the cardboard pallet, since the material itself is basically soft, there is a problem that when the binding band or the like is tightened strongly for strong fixation, the band or the like bites into the cardboard and the binding is easily loosened.

  In particular, in the case of heavy loads, cardboard pallets are difficult to fix with a binding band or the like, so it is inevitably necessary to use wooden pallets in the past, resulting in cost and disposal after use. There was a current situation that there was a problem.

  The present invention has been made in view of the above-described problems of the prior art, and a high-strength industrial waste paper tube is used as a reinforcing member that reinforces the strength of the pallet and a binding member such as a binding band. By using (combining), the load on the pallet can be firmly fixed, and the cardboard pallet with high load resistance and conveyance stability that enables stable transportation of heavy objects can be constructed with a simple configuration. The purpose is to provide it at low cost.

  In order to achieve the above object, a corrugated cardboard pallet with a paper tube according to the present invention includes a top plate that forms a mounting surface on which articles are stacked, a bottom plate that is disposed opposite to the top plate and forms a bottom surface, and the top plate. A girder member interposed between the plate and the bottom plate, and the girder member interposed between the top plate and the four corners of the bottom plate, which are opposed to each other, are a laminated block and paper in which cardboard sheets are laminated. The tube is integrally formed.

  When configured in this way, it is generally easy to obtain as industrial waste, and by appropriately diverting a recyclable thick paper tube, stable transportation of heavy objects and improved load resistance A corrugated cardboard pallet that can be realized at a low cost with a simple configuration.

  ADVANTAGE OF THE INVENTION According to this invention, the corrugated cardboard pallet which makes it possible to divert the highly-recyclable industrial waste paper tube and to stably transport heavy objects and improve the load resistance can be realized with a simple configuration at low cost.

It is a typical perspective view showing composition of a corrugated cardboard pallet with a paper tube concerning the present invention. It is a schematic diagram which shows the structure of the laminated girder with a paper tube which concerns on this invention. It is a schematic diagram which shows the structure of the laminated beam which concerns on this invention. It is a schematic diagram which shows the state which mounted the heavy article on the corrugated cardboard pallet with this invention.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. Here, FIG. 1 is a schematic diagram showing the overall configuration, FIGS. 2 and 3 are schematic diagrams showing the components, and FIG. 4 is a schematic diagram showing a state in which a heavy object is mounted.

  As schematically shown in FIG. 1, a corrugated cardboard pallet 1 according to the present embodiment includes a top plate 10 on which articles are stacked, a bottom plate 30 that forms a bottom surface, and a top plate 10 and a bottom plate 30. A plurality of columnar girder members 20 are provided which form spaces for inserting blades such as forklifts.

  In the present embodiment, the top plate 10 and the bottom plate 30 are, for example, thick board shapes in which two to three reinforced cardboard sheets (double type double-sided cardboard) that have been cut to a predetermined size are laminated and bonded together. Is formed.

  On the other hand, the girder member 20 includes a laminated girder 20A with a paper tube in which a laminated block 20a having a substantially square cross section in which a plurality of cardboard sheets are laminated and a hollow cylindrical paper tube 20b are integrally formed, and a plurality of cardboard sheets. It consists of two types of girder members with a laminated girder 20B formed only of laminated laminated blocks 20a having a substantially square cross section.

  As best shown in FIG. 2, the laminated girder with paper tubes 20A according to the present embodiment is formed on a substantially rectangular parallelepiped laminated block 20a and two adjacent (orthogonal) sides (surfaces) of the laminated block 20a. The bonded paper tube 20b is integrally accommodated in the cover member 20c.

  Specifically, the laminated block 20a is a laminated sheet in which a number of corrugated cardboard sheets are bonded together, and a cut paper tube with a thick wall is integrally formed on two sides (two sides) perpendicular to each other at the periphery. Are adjacently arranged (adhesive arrangement).

  In addition, as the paper tube 20b, it is generally easy to obtain as industrial waste, and a recyclable thick paper tube (for example, a 3 inch paper tube having a thickness of 15 mm) is appropriately used (utilized). be able to.

  Then, the laminated block 20a and the paper tube 20b are once accommodated and bonded in a box-shaped container (not shown) formed of cardboard sheets, and the corresponding box-shaped storage is made so that the end of the paper tube 20b is exposed. A cover member 20c is formed by cutting off the end of the body. In the present embodiment, the cover member 20c can be formed of a cardboard sheet.

  Moreover, in this Embodiment, the magnitude | size of 20 A of lamination | stacking girders with a paper tube is the substantially rectangular parallelepiped shape of each side 150-200 mm by planar view, The height is formed in 90-120 mm.

  In the present embodiment, taking into account the adhesiveness between the laminated block 20b and the cover member 20c, the form of the laminated block 20a in which the corrugated cardboard sheets are horizontally arranged and laminated is illustrated. Corrugated cardboard sheets may be arranged vertically and stacked in order to increase the load bearing performance when mounting (see FIG. 4).

  Thus, by integrating the laminated block 20a and the paper tube 20b into the cover member 20c and integrating them, the integrity of the laminated block 20a and the paper tube 20b as the reinforcing member is improved, and the cardboard pallet 1 is resistant to damage. In addition to contributing to an increase in loadability, the paper tube 20b can also be used as a guide member for inserting a binding band when fixing a load. That is, as schematically shown in FIG. 4, the paper tube 20b can be used both as a guide hole through which the binding band FB is inserted and the function of the reinforcing member, thereby contributing to the cost reduction accompanying the reduction in the number of parts. it can. FIG. 4 schematically shows a state in which a large roll RL having a diameter of 800 mm and 800 to 1,000 kg / piece is fixed by a binding band FB and mounted on the cardboard pallet 1.

  Since the cover member 20c is integrally housed and formed, the stacking direction of the corrugated cardboard sheets constituting the stacked block 20a can be arbitrarily arbitrarily adopted according to the load, application, etc. (for example, as shown in FIG. 1). Such a horizontal arrangement of cardboard sheets, or a vertical arrangement of cardboard sheets in the case of a heavy load product (approximately 800 kg) as shown in FIG. Furthermore, the adhesiveness between the laminated girders with paper tubes 20A, the top plate 10, and the bottom plate 30 can be improved regardless of the laminating direction of the laminated block 20a.

  In the present embodiment, the laminated girder 20B can have a simple configuration in which the paper tube 20b and the cover member 20c of the laminated girder with paper tube 20A are omitted.

  As best shown in FIG. 1, a predetermined portion between the top plate 10 and the bottom plate 30 (in this example, three in each of the end portions in the depth direction and the width direction, and three portions in the center portion, 3 × 3 in total. = 9 places), a plurality of girder members 20 are provided, and the top plate 10, the girder member 20, and the bottom plate 30 are integrally joined using a double-sided joining device or the like.

  More specifically, the laminated girders with paper tubes 20A are arranged at the four corners (four corners) of the top plate 10 and the bottom plate 30 arranged opposite to each other, whereas the laminated girders 20B are arranged with the top plate 10 It is arranged at a total of five locations in the middle (four locations) and the central portion of the (bottom plate 30).

  Note that the size and load resistance of the pallet can be appropriately selected according to the size and weight of the equipment to be loaded.

  As described above, according to the corrugated cardboard pallet 1 with a paper tube according to the present invention, it is generally easy to obtain as industrial waste, and a recyclable wall paper tube (for example, a 3 inch paper tube with a wall thickness of 15 mm). The corrugated cardboard pallet that can stably transport heavy objects and improve the load resistance can be realized at a low cost with a simple configuration.

  Further, the laminated block 20a and the paper tube 20b are accommodated and integrated in the cover member 20c, thereby improving the integrity of the laminated block 20a and the paper tube 20b and increasing the load resistance and bonding of the corrugated cardboard pallet 1. Not only can the workability be improved, but the paper tube 20b can also be used as a guide member through which the bundling member is inserted, thereby contributing to downsizing and cost reduction associated with a reduction in the number of parts.

  The technical scope of the present invention is not limited to the above-described embodiment, and various changes or improvements can be added without departing from the scope of the present invention. For example, the laminated girders with paper tubes 20A exemplified in the embodiment can be applied not only to a cardboard pallet but also to an arbitrary pallet such as a wooden pallet, a resin pallet, and a steel pallet.
