FIG. 9 is a perspective view showing an example of a rack for roll products according to an embodiment of the present invention, and is a partially enlarged view of a rack for roll products to which a brace member is attached.

As shown in FIGS. 1 to 9, the roll product rack (hereinafter, simply referred to as a rack) 1 in the present embodiment is roughly composed of a pallet 11, a corner metal fitting 21, a base frame 31, and a brace member 41. .. Hereinafter, the above components and other detailed components will be described.

The configuration of the pallet 11 will be described.

The pallet 11 is a base of the rack 1 and is a transport stand capable of cargo handling work by a forklift or the like. The material of the pallet 11 is not particularly limited, but for example, resin, steel, or the like can be used, and particularly when it is assumed that a heavy product is stored in the rack 1, high-strength steel is used. Is preferably used. In the present embodiment, the pallet 11 is composed of four side member 12 defining the outer frame of the pallet 11 and a plurality of reinforcing members 13a and 13b connected to the inside of the side member 12 by welding or the like. However, there is no limitation on this configuration. Further, the rack 1 in the present embodiment is configured to accommodate a long roll product in the axial direction, and the outer frame of the pallet 11 defined by the four side member 12 is a roll product to be accommodated. It has a long rectangular shape in the axial direction of.

The structure of the legs of the pallet 11 is arbitrary, but in the present embodiment, the pallet 11 has a predetermined height, and lift openings 14 into which the fork lift claws (forks) are inserted are formed on the four side surfaces thereof. Has been done.

The configuration of the upper surface of the pallet 11 formed by connecting the plurality of reinforcing members 13a and 13b will be described.

The upper surface of the pallet 11 is a surface facing the roll product 100 housed in the rack 1, and is configured to have different heights depending on the position of the pallet 11 in the width direction (short direction). In the present embodiment, the reinforcing members 13a and 13b forming the upper surface of the pallet 11 are composed of square members, and the thickness of the reinforcing member 13b located at the center in the width direction is located at both ends in the width direction. It is set smaller than the thickness of 13a. That is, in the present embodiment, the height of the upper surface of the pallet 11 from the mounting surface of the rack 1 at the center in the width direction is larger than the height of the upper surface of the pallet 11 from the mounting surface of the rack 1 at both ends in the width direction. It is set low. With this configuration, the upper surface of the pallet 11 at the center in the width direction can be made lower than the upper surface at both ends in the width direction while maintaining the strength of the pallet 11, and the shape of the upper surface of the pallet 11 in the width direction is concave in cross section. Can be.

The roll product 100 has a circular cross section, and when the roll product 100 is housed in the rack 1, the branch pipe fixing portion 51 supports and fixes the branch pipe end portion 101 of the roll product 100 as described later. The roll product 100 is in a state of floating in the air without contacting the upper surface of the pallet 11. At this time, the upper surface of the pallet 11 is closer to the axis of the roll product 100 at the center in the width direction than at both ends in the width direction, and is more likely to come into contact with the outer peripheral surface at the lower end of the roll product 100 at the center in the width direction. It becomes a state. In consideration of this state, the central portion in the width direction of the upper surface of the pallet 11 is made lower than both ends in the width direction, so that the outer peripheral surface of the lower end of the roll product 100 is inserted into the recessed portion having a concave cross section on the upper surface of the pallet 11. The roll product 100 can be arranged so as to be recessed so that the roll product 100 can be supported at a lower position in the rack 1. As a result, the ratio of the volume of the roll product 100 that can be accommodated to the volume of the article accommodating space in the rack 1 (accommodation efficiency) is improved, and the height of the rack 1 is lowered to reduce the size of the rack 1. Can be done.

As an example, with respect to the width direction dimension of the upper surface of the pallet 11 (for example, L1 in FIG. 7), the width direction end portions of the pallet 11 (for example, L2 in FIG. 7) and the width direction center portion of the pallet 11 (For example, L3 in FIG. 7) may be set to L2 = (1/4) L1 and L3 = (1/2) L1. As a result, as shown in FIG. 7, the position of the lower end outer peripheral surface of the roll product 100 is set with respect to the upper surfaces of both ends in the width direction of the pallet 11 without bringing the lower end outer peripheral surface of the roll product 100 into contact with the pallet 11. It can be lowered and the storage efficiency of the roll product 100 can be improved. However, the above dimensions are merely an example, and the present invention is not limited thereto.

In the present embodiment, the height of the upper surface of the pallet 11 is set to two levels (two steps) of the height at the central portion in the width direction and the height at both ends in the width direction, but more levels (3 steps). It may be set to (step or higher). Further, if necessary, a floor plate may be placed on the upper surface of the pallet 11. At this time, the floor plate is divided, for example, in the configuration of the present embodiment, one floor plate is placed in the region of the central portion in the width direction in which the upper surface of the pallet 11 is low, and the upper surface of the pallet 11 is formed. By placing one floor plate in each region of both ends in the width direction, which is higher, the floor plate can be placed while maintaining the concave cross-sectional shape of the upper surface of the pallet 11.

The configuration of the corner metal fitting 21 will be described.

Corner metal fittings 21 are installed at each of the four corners of the pallet 11. The corner metal fitting 21 is formed by bending, for example, a steel flat plate member into an L-shaped cross section, and is fixed by welding or the like along the side surfaces of the four corners of the pallet 11.

The two surfaces forming the L-shaped cross section of the corner metal fitting 21 project upward from the upper surface of the pallet 11, so that the surfaces of the corner metal fittings 21 provided at the adjacent corners of the pallet 11 face each other. Have been placed. In the present embodiment, the base frame 31 is erected along the side side of the pallet 11 in the width direction (short direction), and protrudes above the corner metal fittings 21 arranged at both ends in the width direction of the pallet 11. The inside of the two surfaces forming the L-shaped cross section abuts on the support column member 32 of the base frame 31 to support the upright base frame 31. The surface of the corner metal fitting 21 extending in the width direction of the pallet 11 has a role of restricting the support column member 32 of the base frame 31 from moving outward from the state where it is erected substantially vertically. As a result, the base frame 31 is prevented from falling outward.

Further, the corner metal fitting 21 and the base frame 31 are provided with a rotation mechanism that allows the base frame 31 to rotate with respect to the corner metal fitting 21 with the width direction of the pallet 11 as the rotation axis direction. Specifically, in the present embodiment, for example, a vertical hole 22 for a rotating pin is formed on the surface of the corner fitting 21 extending in the longitudinal direction of the pallet 11, while the base frame 31 is described later. The support column member 32 is provided with a rotation pin 35 at a position corresponding to the vertical hole 22 for the rotation pin. By rotating the base frame 31 with respect to the pallet 11 with the rotation pin 35 inserted through the vertical hole 22 for the rotation pin as the rotation axis, the shape of the rack 1 can be changed to an upright form in which the base frame 31 is erected, or The base frame 31 can be folded and housed in a folded form. In the folded form, as shown in FIG. 3, the base frame 31 is housed so as to overlap the upper surface of the pallet 11, and the removed brace member 41 can also be housed on the upper surface of the pallet 11.

The support column member 32 is erected substantially perpendicular to the upper surface of the pallet 11 in a state where the base frame 31 is erected. At this time, the insides of the two surfaces protruding upward from the corner metal fittings 21 come into contact with the support columns 32 of the base frame 31 to support the upright base frame 31.

The strut connecting member 33 is a member that connects a pair of left and right strut members 32. The longitudinal end of the strut connecting member 33 is joined to each of the pair of strut members 32 substantially perpendicularly, and the pair of strut members 32 are integrated via the joining by the strut connecting member 33. The dimension in the width direction of the base frame 31 defined by the dimension of the strut connecting member 33 is such that each of the pair of strut members 32 abuts on the two surfaces of the substantially L-shaped corner metal fitting 21. That is, when the base frame 31 is erected on the upper side of the side surface in the width direction of the pallet 11, the side surfaces of the support columns 32 arranged at both ends of the base frame 31 are in contact with the inner surface of the corner fitting 21. It can be erected at.

The connecting member 34 is joined to the strut member 32 and the strut connecting member 33, and has a role of reinforcing the frame of the base frame 31. In the present embodiment, in the frame composed of the column connecting member 33 and the connecting member 34, a space for providing the branch pipe fixing portion 51 is formed in the vicinity of the central portion of the base frame 31. Specifically, as shown in the figure, a pair of substantially L-shaped connecting members 34 are provided. The ends of the substantially L-shaped connecting member 34 are joined to the strut member 32 and the strut connecting member 33, and the members substantially parallel to the strut member 32 are arranged so as to be separated in the width direction. A space having a concave cross section is formed surrounded by the 33 and the connecting member 34. The branch pipe fixing portion 51 is arranged in the space having a concave cross section.

Further, the corner metal fitting 21 and the base frame 31 are provided with a rotation mechanism that allows the base frame 31 to rotate with respect to the corner metal fitting 21 with the width direction of the pallet 11 as the rotation axis direction. Specifically, the support column member 32 constituting the base frame 31 is provided with a rotation pin 35, while, as described above, the surface of the corner metal fitting 21 extending in the longitudinal direction of the pallet 11 is rotated. A vertical hole 22 for a rotating pin is formed at a position corresponding to the pin 35.

The rotation pin 35 is provided so as to project from the outer surface of the support column member 32 in the width direction of the pallet 11. The rotation pin 35 is fitted so as to be inserted into the rotation pin vertical hole 22 of the corner metal fitting 21. The rotary pin 35 can move in the vertical direction and can rotate in the vertical hole 22 for the rotary pin in a state of being fitted in the vertical hole 22 for the rotary pin.

Further, the corner metal fitting 21 and the base frame 31 are provided with a fixing mechanism that enables the base frame 31 to be fixed to the corner metal fitting 21. Specifically, in the present embodiment, a stopper pin 36 for fixing the support member 32 to the corner metal fitting 21 is provided on the outer surface of the support member 32 when the base frame 31 is erected. As described above, the notch portion 23 is provided on the upper side of the corner metal fitting 21.

The stopper pin 36 is, for example, a substantially L-shaped member that is provided at a predetermined position of the support column member 32, is connected to the support column member 32 at the upper side, and is released at the lower side to form a gap. When the erected support column member 32 is moved downward, the stopper pin 36 is fitted into the notch 23 on the upper side of the corner metal fitting 21, and the support column member 32 and the corner metal fitting 21 are fixed. As a result, the standing form in which the base frame 31 is erected is maintained.
