Description

[Detailed Description of the Invention] (Industrial field of application) The present invention detachably supports each column of a pair of gate-shaped guards arranged in a cross shape along a diagonal line of a flat pallet at four corners of the flat pallet. It relates to a pallet with guards that is made up of at most.

(Prior art and its problems) In this type of guarded pallet, roll-shaped objects loaded on the flat pallet can be prevented from falling from the flat pallet by each column of the gate-shaped guard. Along with it, it has a feature that similar flat pallets etc. can be stacked on the gate type guard, but since the column parts of the gate type guard are arranged only at the four corners of the flat pallet,
Among the loaded roll-like objects, the roll-like objects adjacent to the pillar portions of the gate-shaped guard come into contact with the pillar portions only in the vicinity of both ends thereof. There is a possibility that the central portion may be deformed so that the central portion in the lengthwise direction projects outward due to the load received from another roll-shaped material.

In order to solve such a problem, for example, Jikho Sho 56
As described in JP-A-28924, it has been considered that auxiliary guards are erected in the central regions of both left and right sides parallel to the fork insertion direction of the flat pallet. However, with such an auxiliary guard, in order to receive the central area of the roll-shaped material loaded on the flat pallet, the roll-shaped material is loaded on the flat pallet in the front-back direction parallel to the fork insertion direction. It must be.

As a result, the roll-like object protrudes from the front and rear ends of the flat pallet in the fork insertion direction, and the insertion amount of the fork into the flat pallet becomes shallow,
In particular, for a long roll-shaped object whose protrusion amount from the flat pallet is large, it is not possible to safely lift and convey it with a fork. In a situation where the number of stacked rolls is small and the rolls roll on a flat pallet, the rolls roll in the left and right lateral directions of the fork that lifts the flat pallet. The lifted state of the is very unstable and safe transportation is not possible.

Furthermore, in the conventional example described in the above publication, both ends of the upper end horizontal portion of the auxiliary guard are locked to the upper ends of the pillar-shaped guard posts located at the front and rear ends of the left and right sides of the flat pallet. The length of the upper horizontal part is almost the same as the side length of the flat pallet, which makes the auxiliary guard large.
Not only was it difficult to handle, but the cost was high.

Further, since the upper end level of the auxiliary guard is lower than the upper end level of the gate-shaped guard, it is not possible to stably stack other flat pallets and the like by using the gate-shaped guard and the auxiliary guard, and in the end, Since the other flat pallets are supported only by the gate guard, the auxiliary guard cannot improve the load bearing performance of the gate guard, and there is a drawback that only lightweight items can be stacked.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned conventional problems, and its features are denoted by reference numerals of embodiments described later in parentheses.

(Operation and Effect of Device) As described above, the guarded pallet of the present invention is loaded on a flat pallet by a pair of gate-shaped guard columns and auxiliary guard columns whose upper horizontal portions intersect in a cross shape. It is possible to receive the rolled roll-shaped material at three positions in the longitudinal direction at both ends and the central portion, and it is possible to prevent deformation of the loaded roll-shaped material and to enhance the fall prevention effect. However, in particular, according to the configuration of the present invention, the supporting column of the auxiliary guard is erected at the center positions of the front and rear ends in the fork insertion direction, not on the left and right sides parallel to the fork insertion direction of the flat pallet. Therefore, the roll-shaped objects can be loaded on the flat pallet with the length direction thereof being orthogonal to the fork insertion direction.

Thus, as described above, the roll-shaped objects can be loaded on the flat pallet in a direction in which the length direction thereof is orthogonal to the fork insertion direction, so that the length protruding from the flat pallet becomes long. Even if it is a roll, the fork insertion depth does not become shallow and the fork can be lifted and conveyed stably. Even when the roll-like object rolls on the flat pallet, the roll-like object rolls only to move in the fork length direction at the position of the center of gravity of the entire load and is orthogonal to the fork. The stability is improved as compared with the case of moving in the lateral direction.

In other words, in this way, the roll-shaped objects are stacked on the flat pallet in a direction in which the length direction is orthogonal to the fork insertion direction, and the support part of the auxiliary guard is used while obtaining the above-described operation effects. It is possible to receive the central portion in the longitudinal direction of the loaded roll-shaped material.

Further, according to the structure of the present invention, each auxiliary guard can be constructed by bending one rod-shaped body into an L-shape, and the end of the upper end horizontal part is the center of the gate-shaped guard. Since it is locked by the fitted member provided on the side surface of the intersecting part, the length of the horizontal part is about half of the side length of the flat pallet, and the entire auxiliary guard is small. It can be made lightweight. Therefore, the auxiliary guard can be handled easily and can be implemented at low cost.

Moreover, since the upper surfaces of the horizontal part of each auxiliary guard and the horizontal part of each gate-shaped guard are located on substantially the same horizontal plane, even when stacking other flat pallets etc., a pair of gates can be stacked. Both the shape guard and a pair of auxiliary guards can horizontally and stably support the upper flat pallet, etc., so the load resistance of the guard as a whole is significantly improved, and even heavy objects can be safely stacked. I can.
