Description

The present invention relates to a carrier and a pallet with a carrier.

Patent Document 1 discloses a cart for carrying luggage that is equipped with casters.

Japanese Patent Application Publication No. 2018-161922

The trolley disclosed in Patent Document 1 has a plurality of casters directly attached to the lower surface of a resin platform whose original purpose is to load and store cargo on the upper surface or to transport it with a forklift. It was modified to be used for transporting cargo in the same way as a commercial trolley, and was used as a trolley or used as a substitute. In this way, the trolley with casters attached to the lower surface of the base can be easily moved on the running surface by human power. In addition, in the trolley described in Patent Document 1, the part of the platform on which the cargo is mounted is generally also called a pallet (hereinafter referred to as a pallet in this specification).

In a conventional trolley in which casters are attached to a pallet as shown in Patent Document 1, the casters are generally attached directly to the pallet directly above the caster or with a mounting plate in between. For this reason, shocks and vibrations that occur due to the reaction force from the casters supporting the load of the pallet, the casters colliding with unevenness on the running surface while the trolley is running, and the casters moving up and down depending on the unevenness, are The stress is transmitted to the pallet's caster mounting part without being attenuated, and the stress generated inside the pallet's caster mounting part due to such static loads and the shearing force accompanied by twisting and vibration that is applied to the interface of the caster mounting part are sustained over a long period of time. If it is repeatedly applied, it causes deterioration and damage to the pallet caster attachment parts, impairing the durability of the trolley.
Further, in such a cart, for example, the casters may be removed from the pallet and only the pallet may be cleaned using a cleaning device or the like, or the pallet may be used as the original pallet. However, in the cart of the prior art as shown in Patent Document 1, the casters are independently attached to each of the four corners of the bottom of the pallet, which is formed into a rectangular shape in plan view. The work of removing the casters and attaching the removed casters to the pallet is complicated.

Furthermore, if the casters are attached to the bottom of the pallet, the top surface of the casters will be raised by the height of the casters, and the center of gravity of the cargo to be loaded on the pallet will be raised. From the standpoint of stability when moving the trolley manually, it is preferable that the center of gravity of the load be lower.

The present invention provides a carrier that can improve the durability of a pallet of a cart that uses pallets, facilitates the work of attaching and detaching casters, and improves stability during movement, and a pallet with a carrier. The purpose is to provide

The carrier according to claim 1 includes a long plate-shaped mounting plate that is attached to the bottom of a pallet on which cargo is loaded, and at least two or more casters that are attached along the longitudinal direction of the mounting plate. , the mounting plate is formed between a support part that contacts the bottom of the pallet and is fixed by a fixing means and supports the pallet; and a wall surface that is bent upward and rises above the support part. and a flat part connecting the upper end of the wall part and to which the caster is attached.

The carrier according to claim 1 is used by being placed between a pallet and a running surface. Since the carrier is equipped with casters, it can be easily moved on a running surface.

In the carrier according to claim 1, the transmission of force from the casters to the pallet supported by the support section is first transmitted from the casters to the flat part of the caster attachment part, and from the flat part to the wall part via the bent part, It is transmitted from the wall portion through the bent portion to the support portion, and from the support portion to the pallet through the contact portion between the support portion and the pallet. In this way, the force transmitted from the casters to the pallet is first a reaction force of a magnitude equal to the load that pushes the casters back from the ground when the weight of the cargo loaded on the pallet and the weight of the pallet themselves press the casters against the ground. In addition, when the cart runs, there is an impact force caused by the casters colliding with unevenness on the running surface, and an impact force caused by the acceleration movement caused by moving up and down according to the unevenness, and furthermore, such impact force is generated repeatedly. It is applied and accompanied by vibration, and includes not only a force that pushes the caster upward, but also a torque component that pushes the caster laterally. In a conventional trolley as shown in Patent Document 1, the line of action of the force transmitted from the casters is substantially straight to the pallet, and therefore the force transmitted from the casters is directly applied to the pallet without being subjected to a buffering effect. The reaction force from the caster due to the load generated by the caster creates stress inside the pallet material, and the torque component from the caster acts as a force that peels off the joint surface between the caster and the pallet, and this effect can last for a long time. If this is repeated over a period of time, the pallet will deteriorate or break, and its durability will be impaired. On the other hand, if the carrier according to claim 1 is used, the force from the casters is transmitted through the plane part and the wall part, and is further transmitted to the support part extending in the lateral direction, and then acts on the pallet. By arranging the flat part and the wall part so that they do not touch the pallet, the entire caster mounting part is given room to move laterally due to the elasticity of the material, and the torque component transmitted from the caster is caused by this movement. The vertical movement that is absorbed to some extent and transmitted to the wall surface is not fixed with screws etc. near the bending part of the support part, so the support part near the bending part still acts as a spring due to the elasticity of the material, and the vertical movement is transmitted to the wall surface part. By absorbing the movement to some extent and further increasing the area of the support portion appropriately, it becomes possible to disperse the reaction force from the casters due to the load, and the durability of the pallet is improved.

The flat part of the caster attachment part is located above the support part fixed to the bottom of the pallet, so when the carrier is attached to the pallet, the casters protrude downward from the bottom of the pallet. dimensions become shorter. As a result, compared to when casters are attached directly to the bottom of the pallet, the position of the pallet is lowered and the center of gravity of the cargo loaded on the pallet is also lowered, improving stability when moving the pallet. Can be done.

According to a second aspect of the invention, in the carrier according to the first aspect , the caster attachment portion enters a recess formed in the bottom of the pallet or a through hole vertically penetrating the pallet.

In the carrying device according to claim 2, when the support portion of the mounting plate is attached to the bottom of the pallet, the caster attachment portion enters the recess formed in the bottom of the pallet or the through hole passing through the pallet vertically. The position of the carrier relative to the pallet is determined, and lateral displacement between the pallet and the carrier can be suppressed.

According to a third aspect of the present invention, in the carrier according to the second aspect, the wall portion is inclined and does not come into contact with the inner wall of the recess or the hole wall of the through hole.

The invention according to claim 4 is the transportation tool according to any one of claims 1 to 3, in which the total area of the portion of the support portion in contact with the bottom portion of the pallet in the mounting plate is: It is larger than the total area of the mounting seat plate provided on the caster.

In the carrier according to claim 4, since the total area of the portion of the support portion of the mounting plate that contacts the bottom of the pallet is larger than the total area of the mounting seat plate provided on the caster, the bottom of the pallet The reaction force from the caster that acts on the caster can be dispersed over a wide range. Therefore, the reaction force per unit area acting on the bottom of the pallet is reduced, and the durability of the pallet can be improved.

The invention according to claim 5 is the transportation tool according to any one of claims 1 to 4, wherein the mounting plate is formed in a length that crosses the bottom of the pallet.

In the carrier according to claim 5, since the mounting plate is formed in a length that crosses the bottom of the pallet, the support that comes into contact with the bottom of the pallet is larger than when the mounting plate is not formed in a length that crosses the bottom of the pallet. The area of the pallet can be made wider, and the reaction force from the casters acting on the bottom of the pallet can be easily dispersed.
The invention according to claim 6 is the transportation tool according to any one of claims 1 to 5, wherein the pallet has an insertion hole into which a fork of a forklift is inserted.

The pallet with a carrier according to claim 7 is provided with a recess formed in the bottom or a through hole penetrating vertically, and is attached to the pallet on which cargo is loaded and the bottom of the pallet. It is equipped with the transportation device described in any one of the above .

The pallet with a carrier according to claim 7 has the carrier according to any one of claims 1 to 5 attached to the bottom of the pallet, so that it can be easily moved on a running surface. This also lowers the center of gravity of the loaded cargo, resulting in better stability when moving the pallet. Furthermore, compared to the case where a plurality of casters are individually attached to the four corners of the pallet, removal and attachment operations are easier.

According to the carrier and the pallet with carrier according to the present invention, the durability of the pallet can be improved, the casters can be easily attached and detached from the pallet, and the stability during movement can be improved. You can get excellent results.

[First embodiment]
Hereinafter, a first embodiment of a pallet with a carrier according to the present invention will be described based on the drawings.
As shown in FIGS. 1 and 2, the pallet with carrier 8 according to the present embodiment includes a carrier 10. As shown in FIGS. The carrier 10 has a mounting plate 12 and casters 14. This carrier 10 is attached and used when, for example, a pallet 18 for carrying a cargo 16 on which it is placed is moved manually.

(Palette composition)
The pallet 18 is formed into a substantially square shape when viewed from above, and four recesses 20 are formed in two rows and two columns on the bottom 18A side. The pallet 18 has a bottom portion 18A and an upper portion 18B parallel to each other, and is formed to have a constant thickness. As the pallet 18 of this embodiment, a generally available flat pallet can be used. Further, although the pallet 18 of this embodiment is made of resin, it may be made of other materials.

A rectangular insertion hole 22 is formed in each side of the pallet 18, passing through the opposite side. The insertion hole 22 and the recess 20 intersect and communicate with each other. A fork 26 such as a forklift (not shown) can be inserted into the insertion hole 22 .

(Composition of transportation equipment)
The mounting plate 12 is formed of a rectangular metal plate such as a steel plate. The mounting plate 12 of this embodiment is formed of a steel plate with a thickness of 4.5 mm, as an example, but may be made of other metal plates such as a stainless steel plate or any other material having the required strength (for example, FRP , fiber-reinforced plastic such as GFRP), and the thickness can be changed as necessary.

The mounting plate 12 of this embodiment is formed in a length extending from one side of the pallet 18 to the other side, and traverses the pallet 18. The mounting plate 12 includes a flat support portion 12A that supports the bottom portion 18A of the pallet 18, and two convex bent portions 12B that protrude upward and enter the recess 20. The support portion 12A can be brought into close contact with the bottom portion 18A of the pallet 18.

The convex bent portion 12B is formed by forming a wall portion 12Bs that is bent upward from the support portion 12A and stands up from the support portion 12A, and is bent from the upper end of the wall portion 12Bs in a direction parallel to the support portion 12A. It has a top portion 12Bt as a flat surface portion, and is formed in a trapezoidal shape when viewed from the side, but may be formed in a rectangular shape.

Note that the mounting plate 12 does not necessarily have to be disposed in the horizontal direction (horizontal direction in the paper plane of FIG. 1), but may be in the vertical direction (vertical direction in the paper plane in FIG. 1), diagonal direction, or any other arbitrary direction. The support portions 12A do not necessarily have to extend linearly across the convex bent portion 12B, and may extend radially in plurality, or may spread out in a fan shape or a circular shape. The support portion 12A and the convex bent portion 12B need to be continuous, but the shape of the continuous portion may be any shape.

The convex bent portion 12B of the mounting plate 12 can be easily formed using a press, a bender, or the like.

As shown in FIG. 2, the height of the top portion 12Bt of the convex bent portion 12B is determined so as not to protrude above the bottom surface 22A of the insertion hole 22. This prevents the fork 26 from hitting the convex bent portion 12B when the fork 26 is inserted into the insertion hole 22.

The top portion 12Bt of the convex bent portion 12B is formed flat so as to be parallel to the support portion 12A, and the caster 14 is attached to the lower surface of the top portion 12Bt. In this embodiment, the convex bent portion 12B corresponds to the caster attachment portion of the present invention.

A commercially available product can be used for the casters 14, and a caster mounting seat plate (also called a washer, mounting seat, or top plate; hereinafter referred to as a mounting seat plate in this specification) 14A is attached to the top portion 12Bt with a screw or the like. Fixed. The wheels 14B of the caster 14 of this embodiment are fixed in direction so that the pallet 18 can move in the direction of arrow A in the drawing (referred to as a fixed wheel whose running direction is fixed). As the wheel 14B, a wheel whose outer periphery is coated with resin, elastomer, rubber, etc. can be used.

As shown in FIGS. 1 and 3(B), each support portion 12A is provided with a plurality of holes 30 through which bolts 28 used for attaching the carrier 10 to the pallet 18 are inserted. As shown in FIG. 1, eight holes 30 are formed in the mounting plate 12 of this embodiment, but it is sufficient if there are at least two holes. Further, the type of the bolt 28 is not particularly limited, and any known bolt such as a hexagonal bolt, a hexagon socket flat head bolt, or a butterfly bolt can be used. Note that, depending on the application, the carrier 10 and the pallet 18 do not necessarily have to be fixed with a fixing device such as a bolt, and the convex bent portion 12B of the mounting plate 12 may be simply fitted into the recessed portion of the pallet 18. good.

As shown in FIG. 3(A), the pallet 18 of this embodiment includes a plurality of plate-shaped ribs 32 (not shown in FIG. 1) that intersect with each other. As shown, a plurality of voids 34 are provided that are surrounded by ribs 32 and pass through in the vertical direction. Thereby, the strength of the pallet 18 is ensured, and the weight of the pallet 18 is reduced.

A rectangular block 36 made of a metal material or the like is inserted into the gap 34 facing the hole 30 of the mounting plate 12 of the pallet 18, and a female screw 38 into which the bolt 28 is screwed is formed in the block 36. There is. Block 36 can be fixed to pallet 18 with adhesive or the like.

The carrier 10 can be attached to the pallet 18 by screwing the male thread of the bolt 28 inserted through the hole 30 of the mounting plate 12 into the female thread 38 of the block 36.

In the mounting plate 12 of this embodiment, the total area of the mounting seat plates 14A of all the casters 14 provided per mounting plate 12 is A, and the total area of the mounting seats 14A of all the casters 14 provided per mounting plate 12 is A. More specifically, A<B, where B is the area of the supporting portion 12A, more specifically, the total area of the parts that contact the bottom 18A of the pallet 18.

(action, effect)
Next, the functions and effects of the pallet with carrier 8 of this embodiment will be explained.
The load of the pallet 18 and the cargo 16 (see FIG. 2) placed on the pallet 18 is transferred through the support portion 12A of the mounting plate 12, the convex bent portion 12B, the mounting seat plate 14A of the caster 14, and the wheels 14B. It is supported by a running surface (floor, road, etc.) 42.

In other words, the reaction force from the running surface 42 (force acting in the opposite direction to the load of the luggage 16) is applied to the wheels 14B of the caster 14, the mounting seat plate 14A, the convex bent portion 12B of the mounting plate 12, and the support It is transmitted to the bottom portion 18A of the pallet 18 via the portion 12A.

The mounting plate 12 of this embodiment has a total area of A, which is the sum of the areas of the mounting seat plates 14A of all the casters 14 provided on each mounting plate 12, and all of the areas provided on each mounting plate 12. More specifically, A<B, where B is the area of the supporting portion 12A, more specifically, the total area of the parts that contact the bottom 18A of the pallet 18.

Therefore, the reaction force from the casters 14 acting on the bottom 18A of the pallet 18 can be dispersed over a wide range, and the reaction force acting on the bottom 18A of the pallet 18 can be dispersed over a wide range, compared to when the casters 14 are directly attached to the bottom 18A of the pallet 18. The reaction force per unit area is reduced, and the durability of the pallet 18 can be improved.

In other words, the reaction force (force in the opposite direction of the load) from the running surface 42 transmitted to the bottom 18A of the pallet 18 is not concentrated locally but is dispersed over a wide range, so that the resin pallet 18 has a long lifespan. can improve sexual performance.

Furthermore, in the pallet with carrier 8 of the present embodiment, since the convex bent portion 12B of the mounting plate 12 is apart from the bottom of the recess 20 of the pallet 18, the bottom of the recess 20 of the pallet 18 (compared to other parts) Since the reaction force from the running surface 42 does not act on the thick portion of the pallet 18 (which is thin), the durability of the resin pallet 18 can be improved.

When the pallet 8 with a carrier of this embodiment is seen from the side, a part of the caster 14 enters the recess 20 of the pallet 18, so the height of the pallet 8 with a carrier from the running surface 42 is suppressed. Center of gravity becomes lower. Therefore, the stability during movement of the pallet 8 with a carrier can be improved. Similarly, since the height of the pallet 8 with a carrier is suppressed, space efficiency during storage can be improved.

The carrier 10 can be easily removed from the pallet 18 by removing the bolts 28. As an example, it becomes easy to remove the carrier 10 from the pallet 18 and clean only the pallet 18. Note that the pallet 18 to which the carrier 10 is attached, that is, the pallet with carrier 8 may be cleaned.

Since two casters 14 are attached to the carrier 10, just by attaching and detaching one carrier 10 to and from the pallet 18, two casters 14 are attached and detached from the pallet 18. The attachment/detachment work becomes easier compared to the case where they are individually attached to the pallet 18.

In this embodiment, a resin pallet is used as the pallet 18, but the material of the pallet 18 is not limited to this, and may be made of wood, paper, etc., for example.

In the above embodiment, the casters 14 whose running direction is fixed are attached to the mounting plate 12, but as shown in FIG. A caster 44 called a ball caster 44 may be attached, and as shown in FIG. 5, a ball caster 46 whose movement direction is not limited to a specific direction may be attached. Thereby, the direction of movement of the pallet 18 during movement can be easily changed. Note that the casters 14 attached to the mounting plate 12 are not limited to those of the above embodiment, and may be of other types.

[Second embodiment]
Next, a second embodiment of a pallet with a carrier according to the present invention will be described based on the drawings. Note that the same components as in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 6, the pallet with carrier 50 of this embodiment uses a carrier 52 having a different shape from that of the first embodiment.

The carrier 52 of this embodiment includes a mounting plate 54 made of a steel plate, similar to the first embodiment.
The mounting plate 54 includes a support portion 56 that crosses the bottom portion 18A of the pallet 18, and has L-shaped convex bent portions 58 at both longitudinal ends of the support portion 56.

The support portion 56 is formed flat so as to contact the flat bottom portion 18A of the pallet 18.

The convex bent portion 58 includes a vertical wall 58A extending upward from the end of the support portion 56, an overhang portion 58B extending laterally from the upper end of the vertical wall 58A on the side opposite to the pallet 18, and a side of the vertical wall 58A. It is configured to include a triangular reinforcing wall 58C that connects the end portion and the side end portion of the overhang portion 58B. Note that the triangular reinforcing wall 58C may be provided as needed, and may not be provided. The rigidity (springiness) of the convex bent portion 58 can be adjusted depending on the presence or absence of the reinforcing wall 58C.

Note that the support portion 56, the vertical wall 58A, and the overhang portion 58B are formed of one continuous steel plate, and the vertical wall 58A and the overhang portion 58B are formed by bending the steel plate using a bender, press work, etc. are doing. The reinforcing wall 58C is formed of a triangular steel plate and is welded to the vertical wall 58A and the overhang 58B.
In this embodiment, the convex bent portion 58 corresponds to the caster attachment portion of the present invention.

In this embodiment, casters 14 similar to those in the first embodiment are fixed to the lower surface of the projecting portion 58B with screws or the like (not shown). Note that instead of the casters 14, casters 44 called swivel wheels or ball casters 46 may be attached to the projecting portion 58B.

As shown in FIG. 6, a plurality of holes 30 are appropriately formed in the support portion 56 through which bolts 28 are inserted when attached to the pallet 18. 28, and the pallet 18 may simply be mounted on the support portion 56 of the carrier 52.

In the pallet with carrier 50 of the present embodiment, when the pallet 18 is attached, the upper surface of the projecting portion 58B does not protrude above the bottom surface 22A of the insertion hole 22 (in the present embodiment, The top surface of the overhanging portion 58B and the bottom surface 22A of the insertion hole 22 are flush with each other.)

If the pallet 18 is simply mounted on the support part 56, an anti-slip sheet or the like can be pasted on the support part 56 to prevent the pallet 18 and the carrier 52 from moving in the lateral direction (in this embodiment, as shown in FIG. 6). It is possible to suppress the deviation in B) from the front to the back of the paper.
Furthermore, by providing a protrusion (not shown) on the upper surface of the support part 56 and inserting this protrusion into the gap 34 (see FIG. 3 as an example) surrounded by the ribs 32 of the pallet 18, the pallet 18 and the carrier 52 may be suppressed in the lateral direction.

The carrier 10 of the first embodiment was used for a pallet 18 having a recess 20 formed in the bottom 18A, but the pallet 18 to which the carrier 52 of the present embodiment is attached has a recess 20 in the bottom 18A. It does not have to be provided. Therefore, it can be said that the carrier 52 of the second embodiment has higher versatility than the carrier 10 of the first embodiment.

Furthermore, in the pallet with a carrier 50 of the present embodiment, the height in the height direction from the bottom 18A of the pallet 18 to the lower end of the wheels 14B of the casters 14 is the same as the height from the top 18B of the pallet 18 to the upper surface of the overhang 58B. Since it can be made smaller than the size, multiple sheets can be stacked vertically, and the wheels 14B of the casters 14 of the upper pallet with a carrier 50 will not hit the protrusion 58B of the lower pallet with a carrier 50. . In this embodiment, as in the first embodiment, the height of the pallet 8 with a carrier is suppressed, so that space efficiency during storage can be improved.

[Third embodiment]
Next, a third embodiment of a pallet with a carrier according to the present invention will be described based on the drawings. Note that the same components as in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
As shown in FIGS. 7 and 8, the pallet with a carrier 8 of this embodiment is the pallet with a carrier 8 of the first embodiment with a brake 60 attached thereto.
The brake 60 of this embodiment utilizes, for example, a known clamp that is generally available on the market and is used for fixing articles.

The clamp used in the brake 60 of this embodiment includes a bearing block 62, a link 64, an L-shaped link with a handle 66, and a slide shaft 68 slidably supported by the bearing block 62. These are connected to each other with pins. Note that a brake shoe 70 made of rubber or the like is attached to the lower end of the slide shaft 68.

When the L-shaped link 66 with a handle is tilted in the direction of arrow A in FIG. 7, the slide shaft 68 is lowered and the brake shoe 70 is pressed against the running surface. is configured so that the brake shoes 70 are moved away from the running surface as the brake shoes 70 rise.

The bearing block 62 is formed with a male screw (not shown) through which the slide shaft 68 passes.The male screw is passed through a hole (not shown) in the mounting plate 74, and the hexagonal nut 76 is inserted into the male screw. By tightening, the bearing block 62 is fixed to the mounting plate 74.
Further, this mounting plate 74 is screwed to a rectangular nut plate 76 made of a steel plate and arranged on the bottom surface 22A of the insertion hole 22.

The nut plate 76 is formed with a female screw (not shown), and by screwing the bolt 28 that passes through the pallet 18 into the female screw, the pallet 18 is fixed between the nut plate 76 and the mounting plate 12. The nut plate 76, the mounting plate 12, and the pallet 18 are fixed to each other by being sandwiched therebetween. With this fixing method, since resin pallets usually have gaps between the ribs, by passing the bolts 28 through the gaps in the pallet 18, the mounting plate can be attached without any processing that would impair the pallet's durability. 12 can be fixed to the bottom of the pallet 18. In addition, instead of using the bolt 28 as a through bolt and using the nut plate 76 as a mere patch plate or washer that has a width extending across the gap between the pallet ribs through which the bolt is passed, the mounting plate 12 and its patch plate or washer can be used. Fix the mounting plate 12 to the bottom of the pallet 18 by drilling a hole or a long hole, passing a through bolt through the hole in the mounting plate, the gap in the pallet, and the hole in the backing plate or washer, and screwing a nut onto the tip of the bolt and tightening it. You can also. When using a nut, it is desirable to insert a spring washer in order to maintain stable tightening.

Since the pallet 8 with a carrier 8 of this embodiment is provided with the brake 60, unnecessary movement of the pallet 8 with a carrier 8 can be suppressed by applying the brake shoes 70 to the running surface.
