BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a continuous pallet rack guard device that can prevent cargo from falling off a shelf.

In the industrial rack (JIS Z 0620), the structure and configuration of a pallet rack is such that two supports are connected with upper and lower beams to form a support frame, two sets of support frames are placed on the front and back, the front and back supports are connected with horizontal members and braces, and the front and back upper and lower beams are connected with sub-beams to form a shelf.

Multiple sets of these pallet racks can be linked in the row direction to form a double-row pallet rack, and linked in the row direction to form a linked pallet rack. In the case of a linked pallet rack, the middle support acts as a common support for the rows, and two upper beams and two lower beams are connected to one middle support. Double-row pallet racks and linked pallet racks come in fixed and mobile types.

In such a pallet rack, a pallet loaded with cargo is loaded onto a shelf formed by a beam and a sub-beam through the frontage (opening on the front side of the support frame), but how to operate a pallet rack is There is a flat method in which the front surface of the pallet is approximately aligned with the front surface of the shelf beam, and an overhang method in which the front surface of the pallet is allowed to protrude within 50 mm from the front surface of the shelf beam.

Pallet racks, particularly those operated using the overhanging method, use a guard device that stretches a belt across the width between two posts in an X-shape to prevent stored goods and pallets from falling off the shelves or protruding from the shelves in the event of an earthquake or other disaster. Patent Document 1 discloses a fastener for connecting the belt to the posts.

The fixture of Patent Document 1 is a fixture that is fixed to a shelf support that supports a storage shelf and that fits and connects a connecting fitting at the end of a fall prevention belt, and the fixture is a fixture that is fixed to a shelf support that is fixed to the shelf support. , a pin member that stands upright from the fixed base and into which the connecting fitting fits, and a locking member that is fixed to the distal end side of the pin member to prevent the connecting fitting from coming off; has a base fixed to the fixing base, and a fitting pin part having a smaller diameter than the base and into which the connecting fitting is fitted, and a reinforcing part is provided between the outer periphery of the base and the surface of the fixing base ( Claim 1).

The length of the mating pin portion of the pin member is set to allow multiple connecting fittings to be rotatably mated together (Claim 3).

JP 2022-91515 A

The above-mentioned conventional technology has a base where the pin member is fixed to the fixed base, and a mating pin portion with a smaller diameter than the base into which the connecting fitting fits, and the mating pin portion is set to a length that allows multiple connecting fittings to be rotatably fitted, so that for overhanging pallet racks, the fall prevention belt can be positioned away from the front of the shelf support and beam, and for linked pallet racks, the connecting fittings of the multiple-link fall prevention belt can be doubly connected to the intermediate support.

However, doubly fitting two connecting fittings to one pin member of a fixture is a troublesome work in a narrow space, and an excessive load is placed on one pin member. .

An object of the present invention is to provide a continuous pallet rack guard device that can solve the problems of the prior art.

Embodiments of the present invention will be described below based on the drawings.

FIGS. 1, 7 to 9 show a continuous pallet rack guard device 1 that is applied when double-row continuous pallet racks 3 are fixed in place and operated in an overhanging manner.

The pallet rack forms a support frame by connecting two posts 4 with upper and lower beams 21, and two sets of support frames are arranged on the front and back. The front and back posts 4 are connected with horizontal members 24 and braces 25, and the front and back upper and lower beams 21 are connected with sub-beams 22 to form a shelf.

A plurality of sets of these pallet racks are connected in the row direction to form a double-row pallet rack, and are connected in the continuous direction to form a continuous pallet rack 3. In the case of this continuous pallet rack 3, the intermediate support 4 serves as a common support, and two upper beams 21 and two lower beams 21 are connected to one intermediate support 4.

In such a continuous pallet rack 3, a pallet R carrying a load W is carried in and placed on a shelf formed by a beam 21 and a sub-beam 22 through a frontage M (opening on the front side of the support frame). The baggage W and pallet R are allowed to protrude within a range of 50 mm from the front surface of the shelf beam 21, and the belt B that prevents the baggage W and pallet R from protruding greatly from the shelf or falling is , is stretched forward about 50 mm from the front surface of the pillar 4 and the beam 21. This belt B is stretched across the frontage M in an X-shape between the two pillars 4.

1 to 9, the continuous pallet rack guard device 1 has a plurality of belts B and belt connectors A fixed to the upper and lower parts of each support 4 of the continuous pallet rack 3.

Each of the upper and lower belt connectors A includes a mounting bracket 7 having a U-shaped cross section, a pair of upper and lower engagement pins 5 implanted in the front surface of the mounting bracket 7, and a mounting bracket 7 fixed to the front surface of the support column 4. It has a hang fitting 8 for attaching the holder, and a backing plate 9 which is disposed inside the support post 4 and sandwiches the support post 4 together with the hang fitting 8.

As shown in FIGS. 1, 4, and 6, each support column 4 is a long steel with a U-shaped cross section, and has a large number of front engagement holes 4a formed in the vertical direction on its front surface, and also has vertical engagement holes 4a on its side surface. Numerous side engagement holes 4 on the side
b is formed. The side surface engagement holes 4b are used for passing fasteners for connecting the horizontal members 24 and braces 25.

The hang fitting 8 is formed by bending a band plate into a substantially crank shape when viewed from the side, and the central portion 8a, upper portion 8b, and lower portion 8c are parallel to each other, but are separated by a horizontal portion, and the central portion 8a is parallel to the upper portion 8b and lower portion 8c. The hang fitting 8, which is separated from the upper part 8b and the lower part 8c by 20 to 40 mm, applies the upper part 8b and the lower part 8c to the front surface of the column 4, and attaches the column 4 together with the backing plate 9 with a fastening member 12 that passes through the front engagement hole 4a. is fixed to.

The mounting bracket 7 is made of plate material formed into a U-shaped cross section to increase its strength, and has a main wall 7a that is parallel to the front surface of the support 4, and left and right side walls 7b that bend from the main wall 7a and are spaced apart the width of the support 4. The mounting bracket 7 is formed so that the back surface of the main wall 7a can abut against the front surface of the support 4, and the left and right side walls 7b can abut against the left and right side surfaces of the support 4.

For example, when the dimensions of the front width α1 and side width β1 of the support 4 are 75*75 (mm), the front width of the main wall 7a of the mounting bracket 7 is 85 mm, and the back width α2 of the main wall 7a (left and right side walls 7b distance) is 75 to 76 mm.

The mounting bracket 7 is fixed by a fastening member 11 with the back side of the main wall 7a against the center portion 8a of the hanger 8, and the hanger 8 is interposed between the mounting bracket 7 and the support 4. The main wall 7a of the mounting bracket 7 will be placed 20 to 40 mm away from the front surface of the support column 4.

The mounting bracket 7 has a pair of upper and lower engagement pins 5 implanted (welded) at a distance (center-to-center distance γ) on the front surface of the main wall 7a. The head 5a of the engaging pin 5 has a larger diameter than the body 5b, and engages the engaging body Ba provided at both ends of the belt B with the body 5b, and prevents the engaging body Ba from coming off with the head 5a. It has a shape.

The center distance γ of the upper and lower engagement pins 5 is 80 to 120 mm, which is larger than the front width α1 of the support 4. Because they are positioned above and below in the center of the front of the support 4, the front width of the mounting bracket 7 can be made approximately the same as the front width α1 of the support 4.

If the two engagement pins 5 are spaced apart horizontally, the front width of the mounting bracket 7 will be significantly larger than the front width α1 of the support 4, and will protrude from the support 4, obstructing the loading of cargo W and pallets R onto the shelf.

The engaging body Ba of the belt B has a potbelly hole Bb that connects a large hole through which the head 5a passes and a small hole with a smaller diameter than the head 5a that fits into the body 5b. The length between the engaging bodies Ba at both ends of the belt B can be adjusted by a length adjuster 28.

The length L of the body 5b of the engagement pin 5 is 15 to 25 mm, and the engagement body Ba of the belt B fitted to the body 5b is positioned 35 to 65 mm away from the front surface of the support 4. The height of the center 8a of the hanging fitting 8 and the length of the body 5b of the engagement pin 5 are each set appropriately so that the engagement body Ba of the belt B can be positioned 50 mm away from the front surface of the support 4.

In the continuous pallet rack 3 shown in FIG. 7, the continuous pallet rack guard device 1 fixes the upper and lower belt connectors A to three supports 4, and stretches two belts B in an X shape in each frontage M. There is.

The upper engagement body Ba of the belt B is engaged with the upper engagement pin 5 of the upper belt connector A of the middle support 4, and the lower engagement body Ba of this belt B is engaged with the upper engagement pin 5 of the lower belt connector A of the support 4 adjacent to the middle support 4 in one direction.

At the same time, the upper engaging member Ba of the belt B in the other direction is engaged with the lower engaging pin 5 of the upper belt connector A of the intermediate support 4, and the lower engaging member Ba of the belt B in the other direction is engaged with the lower engaging pin 5 of the upper belt connector A of the intermediate support 4. It is engaged with the lower engagement pin 5 of the lower belt connector A of the column 4 adjacent to the column 4 in the other direction.

The upper and lower engagement pins 5 of the belt connector A of the intermediate support 4 engage with the belts B in one direction and the other direction separately and at a distance. Because they are spaced apart, they can be easily attached and detached, and because they are spaced apart vertically, they do not protrude horizontally from the support 4 and do not impede the loading of the cargo W and pallets R. Even if the cargo W and pallets R are about to fall off the shelf and the belt B is pulled, it can be confirmed that the strength is sufficient to withstand the load.

In addition, each belt B is stretched between the upper engagement pin 5 of the upper belt connector A and the upper engagement pin 5 of the lower belt connector A, and the lower belt of the upper belt connector A. Since the length of the pin tensioned between the dowel pin 5 and the lower engagement pin 5 of the lower belt connector A is approximately the same, preliminary belt length setting in preparation before tensioning work is facilitated.

Each of the upper and lower belt connectors A does not have a hanging bracket 8, but has a mounting bracket 7 with a U-shaped cross section, a pair of upper and lower engagement pins 5 implanted in this mounting bracket 7, and a backing plate 9 that is disposed inside the support 4 and clamps the support 4 together with the mounting bracket 7 and the support 4.

The mounting bracket 7 is the same as the overhanging embodiment, and is made of a sturdy plate material bent into a U-shape. It has a main wall 7a that is parallel to the front surface of the support 4, and left and right side walls 7b that bend from the main wall 7a and are spaced apart by the front width α1 of the support 4. The back surface of the main wall 7a of the mounting bracket 7 is formed so that it can abut against the front surface of the support 4, and the left and right side walls 7b are formed so that they can abut against the left and right side surfaces of the support 4.

For example, when the dimensions of the front width α1 and side width β1 of the support 4 are 75*75 (mm), the front width of the main wall 7a of the mounting bracket 7 is 85 mm, and the back width α2 of the main wall 7a (left and right side walls 7b distance) is 75 to 76 mm.

Therefore, the main wall 7a of the mounting bracket 7 abuts against the front surface of the support 4, and the left and right side walls 7b abut against the left and right side surfaces of the support 4, and a pair of upper and lower engagement pins 5 are positioned close to the front surface of the support 4.

The two belts B stretched from both the left and right sides are separately connected to the pair of upper and lower engagement pins 5 of the belt connector A, and the two belts B are connected in a flat manner. It can be placed in a position corresponding to
