Description

  The present invention relates to a protective cap for a rack suitable for use in a rack on which a load is placed, and more particularly, to a component used in a rack in which a tip end portion of a support protrudes above the uppermost load placement surface. .

  In storage of grain such as brown rice, a packaging material called a ton bag or the like that can store about 1 ton of grain is often used. Conventionally, a tonback containing rice grains was sometimes stacked and stored like a stone wall, but a curing work such as laying a rope to prevent collapse of the cargo occurred, which was complicated and dangerous.

  Therefore, in recent years, steel racks that can individually and independently arrange luggage accommodated in packaging materials such as tonbags have become widespread (see, for example, Patent Document 1). An example of such a steel rack is shown in FIG. The steel rack 20 includes a column 21 erected on a flat base, a beam 22 that connects the columns 21 to each other, and a deck channel 23 that spans between the beams 22. On the deck channel 23, a pallet P that forms a luggage placement surface F is disposed. The pallet P is disposed at a predetermined position of the steel rack 20 by manipulating the forklift in a state where the load B is placed on the load placement surface F. Since the packages B are individually stored in the rack, they can be managed individually according to the loading / unloading date and storage period, and cleaning is also easy.

  The steel rack 20 accommodates a plurality of loads over multiple stages and has a height at regular intervals along the longitudinal direction of the columns 21 so that the height position of the load placement surface F of each stage can be adjusted. A plurality of adjustment holes 24 are formed, and the height position of each stage of the beam 22 can be adjusted by using a lock pin 27 attached to the hole 24. For this reason, the tip end portion of the column 21 may protrude upward from the uppermost load placement surface F (see FIG. 10 and FIG. 12 of Patent Document 1).

JP 2002-2910 A

  In the steel rack 20, the base end portion of the support column 21 is fixed on the base, and when the roll occurs due to a large earthquake, the steel rack 20 easily swings to the left and right as the upper stage side. The support column 21 is formed by bending a steel plate or the like, and has a corner portion that is relatively sharp with respect to a large-capacity load accommodated in a tonback or the like. Therefore, as shown in FIG. 10, when the tip of the support column 21 protrudes upward from the uppermost load placement surface F, the swinging load B pierces the tip of the support column 21 and breaks the packaging material. There is a risk that the contents such as will leak from the tear. If the uppermost package is damaged, the contents are scattered around and it is troublesome to clean up. Further, since the packaging material is opened when the packaging material is torn, there is a problem in that the value of the product is lost for the grain that has been subjected to a predetermined inspection and enclosed.

  In addition, when unloading a package to the top, it is an operation that looks up from the bottom, so it is not noticed that the package protrudes from the outer edge of the pallet, and the package is stuck at the tip of the column, and the package is wrapped. There is a risk of damaging the material.

  An object of the present invention is to solve the above-mentioned problems, for a rack that can safely store a load placed on a rack in which a tip end portion of a support protrudes above the uppermost load placement surface. The object is to provide a protective cap.

  EXAMPLES Hereinafter, although this invention is demonstrated concretely using an Example, this invention is not limited to an Example.

  FIG. 1 is a perspective view showing an example of a steel rack 10 to which the present invention is applied. Similar to the steel rack 10 shown in FIG. 10, the steel rack 10 is the same as the pillars 11 erected at a predetermined interval on a flat base and the beam 12 arranged in the horizontal direction and connecting the pillars 11 to each other. And a deck channel 13 spanning between the beams 12 having a height of 5 mm. A space for placing a load is defined by the column 11, the beam 12, and the deck channel 13, and a pallet P as a loading platform is placed on the deck channel 13 by a cargo handling device such as a forklift.

  Each column 11 is provided with a plurality of height adjusting holes 14 at regular intervals (for example, 50 mm intervals) along the longitudinal direction. The height adjusting holes 14 are formed at two positions in the width direction at the same height position of the support column 11, that is, in two rows along the longitudinal direction. At both ends of the beam 12, a gusset plate 15 having a connecting hole 16 is provided. The mounting height of the beam 12 can be adjusted by aligning the arbitrarily selected height adjusting hole 14 and the connecting hole 16 and mounting the lock pin 17. In the present embodiment, the beam 12 is connected to the upper stage, the middle stage, and the lower stage to form a space in which the pallet P can be arranged in three stages in the height direction. Depending on the mounting height of the beam 12, as shown in FIG. 1, the tip end portion of each column 11 may protrude upward from the load placement surface F of the pallet P disposed at the uppermost stage.

  A rack protective cap 1 according to an embodiment is detachably attached to the front end portions of these columns 11. Next, the configuration of the rack protective cap 1 will be described in detail.

  2 is a plan view of the rack protective cap 1 according to an embodiment, FIG. 3 is a bottom view of the rack protective cap 1 shown in FIG. 2, and FIG. 4 is a diagram of the rack protective cap 1 shown in FIG. FIG. 5 is a cross-sectional view taken along the line XX ′, and FIG. 5 is a perspective view of the rack protective cap 1 shown in FIG. FIG. 6 is a perspective view of the rack protection cap 1 shown in FIG. 2 as viewed from the upper surface side, and the mounting direction of the support column 11 with respect to the tip end portion is indicated by an arrow in the drawing.

  The rack protection cap 1 is a component attached to the rack 10 in which the tip end portion of the support column 11 protrudes above the uppermost load placement surface F, and is disposed above the tip end portion of the support column 11. The cover surface portion 4 that covers the upper surface of the cover surface portion, and the rectangular tube-shaped tubular portion 4 that is provided on the back surface side of the cover surface portion 4 and that is inserted into the distal end portion of the support column 11 and is in sliding contact with the outer peripheral side surface of the support column 11 It has the cap main body 2 formed in the cross-sectional reverse U shape which a bottom face side opens.

  The cap main body 2 is formed of a resin such as plastic, and the cover surface portion 4 and the cylindrical portion 4 are provided integrally. The cylindrical portion 4 includes a front surface portion 4a, a right side surface portion 4b, a left side surface portion 4b, and a back surface portion 4d. The front surface portion 4a and the back surface portion 4d are arranged to face each other in parallel. The surface portion 4c is arranged to face each other in parallel. The cap body is formed of a resin such as plastic or rubber, or a flexible material. The flexible material may be any material that can be bent and deformed, such as plastic or rubber, and it does not matter whether it can be bent.

  The shape and dimensions of the cover surface portion 4 and the cylindrical portion 4 are determined in accordance with the outer shape of the tip end portion of the column 11 to be attached. For example, as in the present embodiment, when the shape of the column 11 is a substantially quadrangular shape when viewed from above, the cylindrical part 4 can be inserted into the tip of the column 11, and the cylindrical part when inserted 4 has a rectangular cylindrical shape with an inner diameter dimension such that the inner peripheral surface is in sliding contact with the outer peripheral side surface of the column 11, and the shape of the cover surface portion 4 is a square shape corresponding to the shape of one open end of the cylindrical portion 4. It shall be plate-shaped. The inner diameter dimension of the cylindrical portion 4 of the present embodiment is slightly larger than the width dimension of the column 11 (for example, about 1 mm), and when the cylindrical portion 4 is fitted to the tip end portion of the column 11, the inner circumferential surface thereof is the outer circumferential side surface of the column 11. It is set to the extent that it slides on. In addition, when a support | pillar is columnar shape, a cylindrical part is formed in a cylindrical shape and the cover surface part 4 is formed circularly by the top view.

  As shown in FIGS. 4 and 6, the outer edge of the cover surface portion 4, that is, the joint portion between the cover surface portion 4 and the cylindrical portion 4 is formed in a smooth rounded arc shape. The cover surface portion 4 has a flat plate shape, and its outer edge is rounded to have an inverted U-shaped cross section, thereby making it difficult to pierce the contacted luggage. The cover surface portion may not be a flat plate shape, but may have a shape that gently bulges into a dome shape.

  By attaching the rack protective cap 1 having the cap body 2 to the tip of each column 11 (see FIG. 1), the tip of each column 11 is covered. As a result, the load placed on the uppermost load placement surface F does not come into direct contact with the tip of the steel post 11 having a corner and is relatively sharp, and the cap body 2 itself is Since the shape is difficult to pierce the luggage B, the luggage B placed on the uppermost stage can be safely stored.

  Since the rack protection cap 1 is detachably attached to the support column 11, the steel rack 10 can be assembled and disassembled by removing it as necessary, and the beam, shelf, etc. disposed on the uppermost stage. There will be no hindrance to the adjustment of the height position.

  In the present embodiment, the rack protective cap 1 has an engaging protrusion 5. The engagement protrusion 5 is a protrusion that protrudes from the inner surface side of the cylindrical portion 4 and enters the hole 14 formed in the tip end portion of the column 11. The engagement protrusion 5 is provided on a surface of the inner surface of the cylindrical portion 4 that is disposed to face the hole 14 when inserted into the tip end portion of the column 11. Note that the engagement protrusions 5 are arbitrarily provided to prevent the protrusions 5 from falling off the support columns, and the number and shape of the engagement protrusions 5 are arbitrarily set corresponding to the shape of the holes 14. Next, the configuration and operation of the engagement protrusion 5 will be described in detail.

  The engaging protrusion 5 is hemispherical or dome-shaped, and corresponds to the position of the hole 14 covered by the cap body 2 when the cap body 2 is inserted into the tip end portion of the support column. Is projected. The engagement protrusion 5 of the present embodiment corresponds to the position of the hole 14 covered by the cap body 2 when the cap body 2 is inserted into the tip end of the support column, and the inner surface of the cylindrical portion 4 (the back surface of the right side surface portion 4b). Are protruded in two places at intervals in the width direction at the same height position. The cap body 2 of this embodiment is made of a plastic resin and can be slightly elastically deformed in the direction in which the opening end (opening dimension) on the bottom side of the cylindrical portion 4 is widened.

  7 is a side view showing a state in which the rack protection cap 1 shown in FIG. 2 is attached to the tip end portion of the column 11, and FIG. 8 is a cross-sectional view of the rack protection cap 1 shown in FIG. FIG. 9 is an explanatory diagram of the internal state of the rack protection cap 1 attached to the tip of the column 11. As shown in FIG. 7 to FIG. 9, by providing such an engaging protrusion 5, when the cap body 2 is inserted into the distal end portion of the column 11, the engaging projection 5 enters the hole 14, and from the distal end portion of the column Dropping is prevented. Although the engagement protrusion 5 can be easily inserted into and removed from the hole 14 by making the shape of the engagement protrusion 5 into a hemisphere or dome shape as in the present embodiment, the shape of the engagement protrusion 5 is not limited to this. May be good

  In addition, by providing the engagement protrusions 5, there is no risk of dropping even if the length of the cylindrical portion 4 in the longitudinal (height) direction is relatively short. Although the protrusion amount of the column tip portion from the uppermost load placement surface F varies depending on the mounting position of the beam 12, the protrusion amount is small by forming the longitudinal dimension of the cylindrical portion 4 relatively short. Can be attached even if.

  The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. In the above embodiment, the upper surface of the pallet P is used as a load placement surface. However, the present invention can be applied to a rack for storing a load using the upper surface of a shelf board or a net shelf as a load placement surface. Further, the rack is not limited to a fixed type, and may be a movable type in which the entire rack moves. The cap body 2 may be painted to improve visibility. When the cargo is unloaded to the uppermost stage, the colored cap body 2 serves as a mark, and it becomes easier to place the luggage and workability is improved.

  The present invention can be used for a rack in which a support protrudes above the uppermost load placement surface.
