In some cases, the lower surface of the lower lower girder 12 is further mounted on the upper surface 22u of the lower plate 22 of the pallet 20, and adjacent to the two lower waists 10 adjacent in the left-right direction. The matching two lower lower girders 12 are mounted on the pallet 20 in a state of being accommodated between the outer side surface 28Lo of the pallet bar 28L and the outer side surface 28Ro of the pallet bar 28R. At this time, the pallet bar 28L and the pallet bar 28R exhibit a function of restricting the movement of the lower waist 10 (the lower waist beam 12) in the left-right direction.

  Further, as shown in FIG. 4 (the right half), between the outer side surface 25o of the pallet girder 25 and the inner side surface 12i of the lower waist girder 12 on the left and right sides of the respective fork receiving portions 24 of the pallet 20 (left-right direction). The distance L2 and the distance H2 (in the vertical direction) between the upper surface 28u of the pallet bar 28 and the lower surface 14d of the lower waist upper plate 14 are used for transporting articles using the article transporting apparatus 1, respectively.

  Note that the center-to-center distance YS1 (see FIG. 4) in the left-right direction of the first fork receiving space S1 formed in each of the pair of fork receiving portions 24 of the pallet 20 and one or more lower waists 10 are the pallet. 20, the center-to-center distance YS2 (see FIG. 4) in the left-right direction of the second fork receiving space S2 formed on both sides of each fork receiving portion 24 in the state of being mounted on each of the fork receiving portions 24 1 is set within a variable range of the distance between the centers of two forks of a transporter used when transporting an article.

  As a result, in the state where the distance between the two forks F (the center-to-center distance) of the transporter is narrowed so as to be substantially equal to the above-described distance YS2, each fork F is connected to the lower waist upper plate 14 of the lower waist 10. 5A, an article to be transported (not shown) carries the lower back 10 on which the article to be transported is placed alone, or the lower lower 10 is placed on the pallet 20 as shown in FIG. Can be mounted on or removed from the pallet 20. At this time, if the distance between the outer side surfaces of the two forks is made slightly smaller than the distance Y1 described above, when the lower back 10 is mounted on the pallet 20 in the state shown in FIG. Each fork is securely accommodated in the second fork receiving space S2, and interference with each member constituting the fork receiving portion 24 can be prevented.

  Further, when the fork F is inserted into the first fork receiving space S1 in a state where the distance between the two forks F of the transporter (distance between the centers) is widened to be substantially equal to the above-described distance YS1, As shown in FIG. 5B, the pallet 20 can be transported together with one or a plurality of lower backs 10 mounted thereon.

  By being configured as described above, the article transporting apparatus 1 of the present invention is applied to transporting the lower back 10 alone or transporting the pallet 20 on which one or more lower backs 10 are mounted. be able to.

  Further, as shown in FIG. 4, the lower back 10 is placed on the lower plate 22 of the pallet 20 so as to straddle the fork receiving portion 24 of the pallet 20. The increase in the total height due to the mounting is only the thickness of the lower waist upper plate 14 and the support plate 16 in the lower waist 10, and the height of the lower waist beam 12 in the lower waist 10 does not cause an increase in the total height. . Therefore, according to the article transporting apparatus 1 of the present invention, the overall height of an object to be transported by a transporter such as a forklift can be kept low. For example, when stacking in two upper and lower stages and storing in a container for improving transport efficiency. Sufficient space can be secured near the ceiling in the container.

  In addition, as shown in FIG. 6, chamfered portions 12Co and 12Ci may be provided at the lower end portions of the outer side surface and the inner side surface of the pair of lower waist girders 12, respectively. Thereby, when the lower back 10 is mounted on the pallet 20, the chamfered portion provided on the inner side surface of the lower back girder 12 even when the lower back 10 is shifted to either the left or right side. Since 12Ci is guided by the upper edge of the outside of the pallet bar 28, it is easy to mount the lower waist 10 at the correct position on the pallet 20. Further, when a new lower waist 10 ′ is mounted on the pallet 20 with the adjacent lower waist 10 already mounted on the pallet 20, the lower waist 10 ′ is already mounted. Even if it is shifted to the 10 side, the chamfered portion 12Co provided on the outer side surface of the lower waist girder 12 (on the already mounted waist 10 side) Since it is guided by the upper edge of the outside of the ten support plates 16, it becomes easy to mount the lower waist 10 ′ at the correct position on the pallet 20.

  In addition, in the above, in order to carry one or several waists simultaneously, although the example which mounts these one or several waists on one pallet was demonstrated, several waists are mutually fixed. By doing so, it is possible to omit the use of the pallet.

  That is, in this embodiment, as shown in FIG. 7, a plurality (four in the illustrated embodiment) of the lower waist 110 are arranged so that the lower waist girders 112 are adjacent to each other in the left-right direction or the front-rear direction. In the state of being aligned, the lower waist girder 112 adjacent to the two lower waists 110 adjacent in the left-right direction is the clip 118Y, and the lower waist beam 112 adjacent to the two lower waists 110 adjacent in the front-rear direction is the clip 118X, respectively. Fixed. Therefore, holes 112a are provided in the vicinity of the front end portion and the rear end portion of each lower girder 112, and adjacent to each other by, for example, folding clips 118X and 118Y made of a band-shaped metal and passing through the holes 112a. Two lower lower girders 112 can be connected.

  In this way, by connecting the lower waists 110 in an aligned state using the clips 118X and 118Y, a plurality of lower waists 110 can be simultaneously transported without using a pallet. That is, as shown in FIG. 7, a plurality of lower waists 110 can be transported simultaneously by inserting the two forks F of the transporter under the lower waist upper plate 114 of two adjacent lower waists 110, respectively. it can.
